A simple approach could be a cron job that\n\/\/ wipes out all cached data if it hasn't been accessed in the past 24 hours:\n\/\/\n\/\/     find \/var\/cache\/rais-s3 -type f -atime +1 -exec rm {} \\;\n\/\/\n\/\/ Depending how fast the cache grows, how much disk space you have available,\n\/\/ and how much variety you have in S3, you may want to monitor the cache\n\/\/ closely and tweak this cron job example as needed, or come up with something\n\/\/ more sophisticated.\n\npackage main\n\nimport (\n\t\"errors\"\n\t\"hash\/fnv\"\n\t\"path\/filepath\"\n\t\"rais\/src\/iiif\"\n\t\"rais\/src\/plugins\"\n\t\"strconv\"\n\t\"sync\"\n\t\"time\"\n\n\t\"github.com\/spf13\/viper\"\n\t\"github.com\/uoregon-libraries\/gopkg\/fileutil\"\n\t\"github.com\/uoregon-libraries\/gopkg\/logger\"\n)\n\nvar downloading = make(map[string]bool)\nvar m sync.RWMutex\n\nvar l *logger.Logger\n\nvar s3cache, s3zone, s3bucket string\n\n\/\/ Disabled lets the plugin manager know not to add this plugin's functions to\n\/\/ the global list unless sanity checks in Initialize() pass\nvar Disabled = true\n\n\/\/ Initialize sets up package variables for the s3 pulls and verifies sanity of\n\/\/ some of the configuration\nfunc Initialize() {\n\tviper.SetDefault(\"S3Cache\", \"\/var\/local\/rais-s3\")\n\ts3cache = viper.GetString(\"S3Cache\")\n\ts3zone = viper.GetString(\"S3Zone\")\n\ts3bucket = viper.GetString(\"S3Bucket\")\n\n\tif s3zone == \"\" {\n\t\tl.Infof(\"S3 plugin will not be enabled: S3Zone must be set in rais.toml or RAIS_S3ZONE must be set in the environment\")\n\t\treturn\n\t}\n\n\tif s3bucket == \"\" {\n\t\tl.Infof(\"S3 plugin will not be enabled: S3Bucket must be set in rais.toml or RAIS_S3BUCKET must be set in the environment\")\n\t\treturn\n\t}\n\n\tl.Debugf(\"Setting S3 cache location to %q\", s3cache)\n\tl.Debugf(\"Setting S3 zone to %q\", s3zone)\n\tl.Debugf(\"Setting S3 bucket to %q\", s3bucket)\n\tDisabled = false\n\n\tif fileutil.IsDir(s3cache) {\n\t\treturn\n\t}\n\tif !fileutil.MustNotExist(s3cache) {\n\t\tl.Fatalf(\"S3 plugin failure: %q must not exist or else must be a directory\", s3cache)\n\t}\n}\n\n\/\/ SetLogger is called by the RAIS server's plugin manager to let plugins use\n\/\/ the central logger\nfunc SetLogger(raisLogger *logger.Logger) {\n\tl = raisLogger\n}\n\nfunc buckets(s3ID string) (string, string) {\n\tvar h = fnv.New32()\n\th.Write([]byte(s3ID))\n\tvar val = int(h.Sum32() \/ 10000)\n\treturn strconv.Itoa(val % 100), strconv.Itoa((val \/ 100) % 100)\n}\n\n\/\/ IDToPath implements the auto-download logic when a IIIF ID\n\/\/ starts with \"s3:\"\nfunc IDToPath(id iiif.ID) (path string, err error) {\n\tvar ids = string(id)\n\tif len(ids) < 4 {\n\t\treturn \"\", plugins.ErrSkipped\n\t}\n\n\tif ids[:3] != \"s3:\" {\n\t\treturn \"\", plugins.ErrSkipped\n\t}\n\n\t\/\/ Check cache - don't re-download\n\tvar s3ID = ids[3:]\n\tvar bucket1, bucket2 = buckets(s3ID)\n\tpath = filepath.Join(s3cache, bucket1, bucket2, s3ID)\n\n\t\/\/ See if this file is currently being downloaded; if so we need to wait\n\tvar timeout = time.Now().Add(time.Second * 10)\n\tfor isDownloading(s3ID) {\n\t\ttime.Sleep(time.Millisecond * 250)\n\t\tif time.Now().After(timeout) {\n\t\t\treturn \"\", errors.New(\"timed out waiting for s3 download\")\n\t\t}\n\t}\n\n\tif fileutil.MustNotExist(path) {\n\t\tl.Debugf(\"s3-images plugin: no cached file at %q; downloading from S3\", path)\n\t\terr = pullImage(s3ID, path)\n\t}\n\n\treturn path, err\n}\n\nfunc pullImage(s3ID, path string) error {\n\tsetIsDownloading(s3ID)\n\tdefer clearIsDownloading(s3ID)\n\treturn s3download(s3ID, path)\n}\n\nfunc isDownloading(s3ID string) bool {\n\tm.RLock()\n\tdefer m.RUnlock()\n\treturn downloading[s3ID]\n}\n\nfunc setIsDownloading(s3ID string) {\n\tm.Lock()\n\tdefer m.Unlock()\n\tdownloading[s3ID] = true\n}\n\nfunc clearIsDownloading(s3ID string) {\n\tm.Lock()\n\tdefer m.Unlock()\n\tdelete(downloading, s3ID)\n}\n<|endoftext|>"}

It can be a\n\/\/ machine learning model, a data structure for aggregation (like a histgram),\n\/\/ a configuration information for specific Boxes, and so on.\n\/\/\n\/\/ SharedState doesn't have methods to read it's internal data because internal\n\/\/ data representation heavily depends on each SharedState implementation. The\n\/\/ easiest way to use SharedState from a component is to obtain the actual\n\/\/ data type via the type assertion. See examples to learn more about how to\n\/\/ use it.\n\/\/\n\/\/ If a SharedState also implements Writer interface, it can be updated via\n\/\/ SharedStateSink. Write method in it writes a tuple to the state. How tuples\n\/\/ are processed depends on each SharedState. For example, a machine learning\n\/\/ model might use a tuple as a training data, and another state could compute\n\/\/ the average of a specific field. Write may return fatal or temporary errors\n\/\/ as Box.Process does. See the documentation of Box.Process for details.\n\/\/\n\/\/ Write method might be called after Terminate method is called. When it\n\/\/ occurs, Write should return an error. Also, Write and Terminate can be\n\/\/ called concurrently.\ntype SharedState interface {\n\t\/\/ Terminate finalizes the state.

The incoming request\n\t\/\/   rate is dictated by the task queue, and ultimately the handler\n\t\/\/   must reject 10% of the incoming requests.

For NDT, the 100MB tasks require about 35 concurrent tasks\n\t\/\/   to process 60 tasks\/min, indicating that they require about 35\n\t\/\/   seconds per task.  There are about 70 tests\/task, so this is about\n\t\/\/   7 buffer flushes per second (of 10 tests each), or on average, about\n\t\/\/   one buffer flush every 5 seconds for each task.\n\t\/\/  The batch job might have 50 instances, and process 900 tasks\n\t\/\/   concurrently.  If this had to be scaled back to 50%, the tasks\n\t\/\/   would have to spend 50% of their time sleeping between Put requests.\n\t\/\/   Since each task typically takes about 35 seconds, each task would\n\t\/\/   on average experience just over one 'Quota exceeded' error in order\n\t\/\/   to slow the pipeline down by 50%.\n\t\/\/  Note that a secondary effect is to reduce the CPU utilization, which\n\t\/\/   will likely trigger a reduction in the number of instances running.\n\t\/\/   Under these conditions, AppEngine would reduce the number of instances\n\t\/\/   until the target utilization is reaches, reducing the number of\n\t\/\/   concurrent tasks, and thus the frequency at which the tasks would\n\t\/\/   experience 'Quota error' events.\n\n\tvar err error\n\tfor i := 0; i < 10; i++ {\n\t\t\/\/ This is heavyweight, and may run forever without a context deadline.\n\t\tctx, _ := context.WithTimeout(context.Background(), in.timeout)\n\t\terr = in.uploader.Put(ctx, in.rows)\n\t\tif err == nil || !strings.Contains(err.Error(), \"Quota exceeded:\") {\n\t\t\tbreak\n\t\t}\n\t\tmetrics.WarningCount.WithLabelValues(in.TableBase(), \"\", \"Quota Exceeded\").Inc()\n\t\t\/\/ Use some randomness to reduce risk of synchronization across tasks.\n\t\tt := in.params.RetryDelay.Seconds() * (0.5 + rand.Float64()) \/\/ between 0.5 and 1.5 * RetryDelay\n\t\ttime.Sleep(time.Duration(1000000*t) * time.Microsecond)\n\t}\n\n\t\/\/ If there is still an error, then handle it.\n\tif err == nil {\n\t\tin.inserted += len(in.rows)\n\t} else {\n\t\t\/\/ This adjusts the inserted count, failure count, and updates in.rows.\n\t\terr = in.HandleInsertErrors(err)\n\t}\n\t\/\/ Allocate new slice of rows.

If this had to be scaled back to 50%, the tasks\n\t\/\/   would have to spend 50% of their time sleeping between Put requests.\n\t\/\/   Since each task typically takes about 35 seconds, each task would\n\t\/\/   on average experience just over one 'Quota exceeded' error in order\n\t\/\/   to slow the pipeline down by 50%.\n\t\/\/  Note that a secondary effect is to reduce the CPU utilization, which\n\t\/\/   will likely trigger a reduction in the number of instances running.\n\t\/\/   Under these conditions, AppEngine would reduce the number of instances\n\t\/\/   until the target utilization is reaches, reducing the number of\n\t\/\/   concurrent tasks, and thus the frequency at which the tasks would\n\t\/\/   experience 'Quota error' events.\n\n\tvar err error\n\tfor i := 0; i < 10; i++ {\n\t\t\/\/ This is heavyweight, and may run forever without a context deadline.\n\t\tctx, _ := context.WithTimeout(context.Background(), in.timeout)\n\t\terr = in.uploader.Put(ctx, in.rows)\n\t\tif err == nil || !strings.Contains(err.Error(), \"Quota exceeded:\") {\n\t\t\tbreak\n\t\t}\n\t\tmetrics.WarningCount.WithLabelValues(in.TableBase(), \"\", \"Quota Exceeded\").Inc()\n\t\t\/\/ Use some randomness to reduce risk of synchronization across tasks.\n\t\tt := in.params.RetryDelay.Seconds() * (0.5 + rand.Float64()) \/\/ between 0.5 and 1.5 * RetryDelay\n\t\ttime.Sleep(time.Duration(1000000*t) * time.Microsecond)\n\t}\n\n\t\/\/ If there is still an error, then handle it.\n\tif err == nil {\n\t\tin.inserted += len(in.rows)\n\t} else {\n\t\t\/\/ This adjusts the inserted count, failure count, and updates in.rows.\n\t\terr = in.HandleInsertErrors(err)\n\t}\n\t\/\/ Allocate new slice of rows.

Cards, dice, meeples,\n\/\/resource tokens, etc are all components. Values is a struct that stores the\n\/\/specific values for the component. Components are the same across all games\n\/\/of this type. Component references should not be compared directly for\n\/\/equality, as sometimes different underlying objects will represent the same\n\/\/notional component (in order to satisfy both the Component and\n\/\/ComponentInstance interfaces simultaneously). Instead, use Equivalent() to\n\/\/test that two Components refer to the same conceptual Component.\ntype Component interface {\n\tValues() ComponentValues\n\tDeck() *Deck\n\tDeckIndex() int\n\t\/\/Equivalent checks whether two components are equivalent--that is,\n\t\/\/whether they represent the same index in the same deck.\n\tEquivalent(other Component) bool\n\n\t\/\/Instance returns a ComponentInstance representing this component in the\n\t\/\/given state.\n\tInstance(st State) ComponentInstance\n\n\t\/\/ptr() is used for when the component itself is used as a key into\n\t\/\/an index and equality is important.\n\tptr() *component\n}\n\n\/\/ComponentInstance is a specific instantiation of a component as it exists in\n\/\/the particular State it is associated with. ComponentInstances also\n\/\/implement all of the Component information, as a convenience you often need\n\/\/both bits of inforamation.  The downside of this is that two Component\n\/\/values can't be compared directly for equality because they may be different\n\/\/underlying objects and wrappers. If you want to see if two Components that\n\/\/might be from different states refer to the same underlying conceptual\n\/\/Component, use Equivalent(). However, ComponentInstances compared with\n\/\/another ComponentInstance for the same component in the same state will be\n\/\/equal.\ntype ComponentInstance interface {\n\t\/\/ComponentInstances have all of the information of a base Component, as\n\t\/\/often that's the information you most need.\n\tComponent\n\n\t\/\/ID returns a semi-stable ID for this component within this game and the\n\t\/\/current state this component instance is associated with.

Across games the Id for the \"same\" component will be different,\n\t\/\/in a way that cannot be guessed without access to game.SecretSalt.

You generally get these from a MutableStack that contains them. The\n\/\/instance contains many methods to move the component to other stacks or\n\/\/locations.\ntype MutableComponentInstance interface {\n\tComponentInstance\n\n\t\/\/MoveTo moves the specified component in its current stack to the\n\t\/\/specified slot in the destination stack.

In destination, slotIndex\n\t\/\/must point to a valid \"slot\" to put a component, such that after\n\t\/\/insertion, using that index on the destination will return that\n\t\/\/component. In defaults Stacks, slots are any index from 0 up to and\n\t\/\/including stack.Len(), because the stack will grow to insert the\n\t\/\/component between existing components if necessary. For SizedStacks,\n\t\/\/slotIndex must point to a currently empty slot.\n\t\/\/MoveTo{First,Last,Next}Slot methods are useful if you want to move to\n\t\/\/those locations.

Cards, dice, meeples,\n\/\/resource tokens, etc are all components. Values is a struct that stores the\n\/\/specific values for the component. Components are the same across all games\n\/\/of this type. Component references should not be compared directly for\n\/\/equality, as sometimes different underlying objects will represent the same\n\/\/notional component (in order to satisfy both the Component and\n\/\/ComponentInstance interfaces simultaneously). Instead, use Equivalent() to\n\/\/test that two Components refer to the same conceptual Component.\ntype Component interface {\n\tValues() ComponentValues\n\tDeck() *Deck\n\tDeckIndex() int\n\t\/\/Equivalent checks whether two components are equivalent--that is,\n\t\/\/whether they represent the same index in the same deck.\n\tEquivalent(other Component) bool\n\n\t\/\/Instance returns a ComponentInstance representing this component in the\n\t\/\/given state.\n\tInstance(st State) ComponentInstance\n\n\t\/\/Generic returns true if this Component is the generic component for this\n\t\/\/deck.

This method is a convenience method equivalent to\n\t\/\/checking for equivalency to Deck().GenericComponent().\n\tGeneric() bool\n\n\t\/\/ptr() is used for when the component itself is used as a key into\n\t\/\/an index and equality is important.\n\tptr() *component\n}\n\n\/\/ComponentInstance is a specific instantiation of a component as it exists in\n\/\/the particular State it is associated with. ComponentInstances also\n\/\/implement all of the Component information, as a convenience you often need\n\/\/both bits of inforamation.  The downside of this is that two Component\n\/\/values can't be compared directly for equality because they may be different\n\/\/underlying objects and wrappers. If you want to see if two Components that\n\/\/might be from different states refer to the same underlying conceptual\n\/\/Component, use Equivalent(). However, ComponentInstances compared with\n\/\/another ComponentInstance for the same component in the same state will be\n\/\/equal.\ntype ComponentInstance interface {\n\t\/\/ComponentInstances have all of the information of a base Component, as\n\t\/\/often that's the information you most need.\n\tComponent\n\n\t\/\/ID returns a semi-stable ID for this component within this game and the\n\t\/\/current state this component instance is associated with.

Across games the Id for the \"same\" component will be different,\n\t\/\/in a way that cannot be guessed without access to game.SecretSalt.

Similarly, each time a timeseriesinfo is accessed, it is also marked.\n\/\/\n\/\/ At the end of each JobsMap.get(), if the last time the JobsMap was gc'd exceeds the 'gcInterval',\n\/\/ the JobsMap is locked and any timeseriesMaps that are unmarked are removed from the JobsMap\n\/\/ otherwise the timeseriesMap is gc'd\n\/\/\n\/\/ The gc for the timeseriesMap is straightforward - the map is locked and, for each timeseriesinfo\n\/\/ in the map, if it has not been marked, it is removed otherwise it is unmarked.\n\/\/\n\/\/ Alternative Strategies\n\/\/ 1. If the job-level gc doesn't run often enough, or runs too often, a separate go routine can\n\/\/    be spawned at JobMap creation time that gc's at periodic intervals. This approach potentially\n\/\/    adds more contention and latency to each scrape so the current approach is used. Note that\n\/\/    the go routine will need to be cancelled upon Shutdown().\n\/\/ 2. If the gc of each timeseriesMap during the gc of the JobsMap causes too much contention,\n\/\/    the gc of timeseriesMaps can be moved to the end of MetricsAdjuster().AdjustMetricSlice(). This\n\/\/    approach requires adding 'lastGC' Time and (potentially) a gcInterval duration to\n\/\/    timeseriesMap so the current approach is used instead.\n\n\/\/ timeseriesinfo contains the information necessary to adjust from the initial point and to detect resets.\ntype timeseriesinfo struct {\n\tmark bool\n\n\tnumber    numberInfo\n\thistogram histogramInfo\n\tsummary   summaryInfo\n}\n\ntype numberInfo struct {\n\tstartTime     pcommon.Timestamp\n\tpreviousValue float64\n}\n\ntype histogramInfo struct {\n\tstartTime     pcommon.Timestamp\n\tpreviousCount uint64\n\tpreviousSum   float64\n}\n\ntype summaryInfo struct {\n\tstartTime     pcommon.Timestamp\n\tpreviousCount uint64\n\tpreviousSum   float64\n}\n\n\/\/ timeseriesMap maps from a timeseries instance (metric * label values) to the timeseries info for\n\/\/ the instance.\ntype timeseriesMap struct {\n\tsync.RWMutex\n\t\/\/ The mutex is used to protect access to the member fields.

For example:\n\/\/ ```bash\n\/\/ go run .\/pilot\/tools\/debug\/pilot_cli.go --type eds --proxytag httpbin \\\n\/\/ --res \"inbound|http||sleep.default.svc.cluster.local,outbound|http||httpbin.default.svc.cluster.local\"\n\/\/ ```\n\/\/\n\/\/ Script requires kube config in order to connect to k8s registry to get pod information (for LDS and CDS type). The default\n\/\/ value for kubeconfig path is .kube\/config in home folder (works for Linux only). It can be changed via -kubeconfig flag.\n\/\/ ```bash\n\/\/ go run .\/pilot\/debug\/pilot_cli.go --type lds --proxytag httpbin --kubeconfig path\/to\/kube\/config\n\/\/ ```\n\npackage main\n\nimport (\n\t\"context\"\n\t\"flag\"\n\t\"fmt\"\n\t\"io\/ioutil\"\n\t\"math\/rand\"\n\t\"net\"\n\t\"os\"\n\t\"os\/exec\"\n\t\"path\/filepath\"\n\t\"strings\"\n\t\"time\"\n\n\tcore \"github.com\/envoyproxy\/go-control-plane\/envoy\/config\/core\/v3\"\n\tdiscovery \"github.com\/envoyproxy\/go-control-plane\/envoy\/service\/discovery\/v3\"\n\t\"google.golang.org\/grpc\"\n\tv1 \"k8s.io\/api\/core\/v1\"\n\tmeta_v1 \"k8s.io\/apimachinery\/pkg\/apis\/meta\/v1\"\n\t\"k8s.io\/client-go\/kubernetes\"\n\t_ \"k8s.io\/client-go\/plugin\/pkg\/client\/auth\/gcp\"\n\t\"k8s.io\/client-go\/tools\/clientcmd\"\n\n\tv3 \"istio.io\/istio\/pilot\/pkg\/xds\/v3\"\n\t\"istio.io\/istio\/pkg\/util\/gogoprotomarshal\"\n\t\"istio.io\/pkg\/env\"\n\t\"istio.io\/pkg\/log\"\n)\n\nconst (\n\tLocalPortStart = 50000\n\tLocalPortEnd   = 60000\n)\n\n\/\/ PodInfo holds information to identify pod.\ntype PodInfo struct {\n\tName      string\n\tNamespace string\n\tIP        string\n\tProxyType string\n}\n\nfunc getAllPods(kubeconfig string) (*v1.PodList, error) {\n\tcfg, err := clientcmd.BuildConfigFromFlags(\"\", kubeconfig)\n\tif err != nil {\n\t\treturn nil, err\n\t}\n\tclientset, err := kubernetes.NewForConfig(cfg)\n\tif err != nil {\n\t\treturn nil, err\n\t}\n\treturn clientset.CoreV1().Pods(meta_v1.NamespaceAll).List(context.TODO(), meta_v1.ListOptions{})\n}\n\nfunc NewPodInfo(nameOrAppLabel string, kubeconfig string, proxyType string) *PodInfo {\n\tlog.Infof(\"Using kube config at %s\", kubeconfig)\n\tpods, err := getAllPods(kubeconfig)\n\tif err != nil {\n\t\tlog.Errorf(err.Error())\n\t\treturn nil\n\t}\n\n\tfor _, pod := range pods.Items {\n\t\tlog.Infof(\"pod %q\", pod.Name)\n\t\tif pod.Name == nameOrAppLabel {\n\t\t\tlog.Infof(\"Found pod %s.%s~%s matching name %q\", pod.Name, pod.Namespace, pod.Status.PodIP, nameOrAppLabel)\n\t\t\treturn &PodInfo{\n\t\t\t\tName:      pod.Name,\n\t\t\t\tNamespace: pod.Namespace,\n\t\t\t\tIP:        pod.Status.PodIP,\n\t\t\t\tProxyType: proxyType,\n\t\t\t}\n\t\t}\n\t\tif app, ok := pod.ObjectMeta.Labels[\"app\"];

subject to change.\n\/\/\n\/\/ The syntax is based on that used by git config:\n\/\/ http:\/\/git-scm.com\/docs\/git-config#_syntax .\n\/\/ There are some (planned) differences compared to the git config format:\n\/\/  - improve data portability:\n\/\/    - must be encoded in UTF-8 (for now) and must not contain the 0 byte\n\/\/    - include and \"path\" type is not supported\n\/\/      (path type may be implementable as a user-defined type)\n\/\/  - disallow potentially ambiguous or misleading definitions:\n\/\/    - `[sec.sub]` format is not allowed (deprecated in gitconfig)\n\/\/    - `[sec \"\"]` is not allowed\n\/\/      - use `[sec]` for section name \"sec\" and empty subsection name\n\/\/    - within a single file, definitions must be consecutive for each:\n\/\/      - section: '[secA]' -> '[secB]' -> '[secA]' is an error\n\/\/      - subsection: '[sec \"A\"]' -> '[sec \"B\"]' -> '[sec \"A\"]' is an error\n\/\/      - multivalued variable: 'multi=a' -> 'other=x' -> 'multi=b' is an error\n\/\/\n\/\/ The package may be usable for handling some of the various \"INI file\" formats\n\/\/ used by some programs and libraries, but achieving or maintaining\n\/\/ compatibility with any of those is not a primary concern.\n\/\/\n\/\/ TODO:\n\/\/  - format\n\/\/    - explain \"why gcfg\"\n\/\/    - define valid section and variable names\n\/\/    - define handling of default value\n\/\/    - complete syntax documentation\n\/\/  - reading\n\/\/    - define internal representation structure\n\/\/    - support multi-value variables\n\/\/    - non-regexp based parser\n\/\/    - support partially quoted strings\n\/\/    - support escaping in strings\n\/\/    - support multiple inputs (readers, strings, files)\n\/\/    - support declaring encoding (?)\n\/\/    - support pointer fields\n\/\/    - support varying fields sets for subsections (?)\n\/\/  - scanEnum\n\/\/    - should use longest match (?)\n\/\/    - support matching on unique prefix (?)\n\/\/  - writing gcfg files\n\/\/  - error handling\n\/\/    - include error context\n\/\/    - avoid reflection-related panics\n\/\/    - more helpful error messages\n\/\/    - error types \/ codes?\n\/\/    - limit input size?\n\/\/  - move TODOs to issue tracker (eventually)\n\/\/\npackage gcfg\n\nimport

must be a pointer to a struct.\n\/\/ Each section corresponds to a struct field in config, and each variable in a\n\/\/ section corresponds to a data field in the section struct.\n\/\/ The name of the field must match the name of the section or variable,\n\/\/ ignoring case.\n\/\/ Hyphens in variable names correspond to underscores in section or field\n\/\/ names.\n\/\/\n\/\/ For sections with subsections, the corresponding field in config must be a\n\/\/ map, rather than a struct, with string keys and pointer-to-struct values.\n\/\/ Values for subsection variables are stored in the map with the subsection\n\/\/ name used as the map key.\n\/\/ (Note that unlike section and variable names, subsection names are case\n\/\/ sensitive.)\n\/\/ When using a map, and there is a section with the same section name but\n\/\/ without a subsection name, its values are stored with the empty string used\n\/\/ as the key.\n\/\/\n\/\/ The section structs in the config struct may contain arbitrary types.\n\/\/ For string fields, the (unquoted and unescaped) value string is assigned to\n\/\/ the field.\n\/\/ For bool fields, the field is set to true if the value is \"true\", \"yes\", \"on\"\n\/\/ or \"1\", and set to false if the value is \"false\", \"no\", \"off\" or \"0\",\n\/\/ ignoring case.\n\/\/ For all other types, fmt.Sscanf is used to parse the value and set it to the\n\/\/ field.\n\/\/ This means that built-in Go types are parseable using the standard format,\n\/\/ and any user-defined type is parseable if it implements the fmt.Scanner\n\/\/ interface.\n\/\/

All rights reserved.\n\/\/ Use of this source code is governed by a BSD-style\n\/\/ license that can be found in the LICENSE file.\n\n\/\/ This file provides tests for all refactorings.

E.g.::\n\/\/     go test -filter=rename              # Only run rename tests\n\/\/     go test -filter=shortassign\/003     # Only run shortassign test #3\n\/\/\n\/\/ Refactorings are run on the files in each test directory; special comments\n\/\/ in the .go files indicate what refactoring(s) to run and whether the\n\/\/ refactorings are expected to succeed or fail.  Specifically, test files are\n\/\/ annotated with markers of the form\n\/\/     \/\/<<<<<name,startline,startcol,endline,endcol,arg1,arg2,...,argn,pass\n\/\/ The name indicates the refactoring to run.  The next four fields specify a\n\/\/ text selection on which to invoke the refactoring.  The arguments\n\/\/ arg1,arg2,...,argn are passed as arguments to the refactoring (see\n\/\/ Config.Args).  The last field is either \"pass\" or \"fail\", indicating whether\n\/\/ the refactoring is expected to complete successfully or raise an error.  If\n\/\/ the refactoring is expected to succeed, the resulting file is compared\n\/\/ against a .golden file with the same name in the same directory.\n\/\/\n\/\/ Each test directory (001-test-name, 002-test-name, etc.) is treated as the\n\/\/ root of a Go workspace when its tests are run; i.e., the GOPATH is set to\n\/\/ the test directory.  This allows it to define its own packages.  In such\n\/\/ cases, the test directory is usually structured as follows:\n\/\/\n\/\/     testdata\/\n\/\/         refactoring-name\/\n\/\/             001-test-name\/\n\/\/                 src\/\n\/\/                     main.go\n\/\/                     main.golden\n\/\/                     package-name\/\n\/\/                         package-file.go\n\/\/                         package-file.golden\n\/\/\n\/\/ To additional options are available and are currently used only to test the\n\/\/ Debug refactoring.  When it does not make sense to compare against a .golden\n\/\/ file, include an empty file named filename.golden.ignoreOutput instead.  If\n\/\/ the output will contain absolute paths to files in the test folder, include\n\/\/ a file named filename.go.stripPaths, and the refactoring's output will be\n\/\/ stripped of all occurrences of the absolute path to the .go file.\n\npackage refactoring_test\n\nimport

2014 The Go Authors. All rights reserved.\n\/\/ Use of this source code is governed by a BSD-style\n\/\/ license that can be found in the LICENSE file.\n\n\/\/ This file provides tests for all refactorings.  The testdata directory is\n\/\/ structured as such:\n\/\/\n\/\/     testdata\/\n\/\/         refactoring-name\/\n\/\/             001-test-name\/\n\/\/             002-test-name\/\n\/\/\n\/\/ To filter which refactorings are tested, run\n\/\/     go test -filter=something\n\/\/ Then, only tests in directories containing \"something\" are run.  E.g.::\n\/\/     go test -filter=rename              # Only run rename tests\n\/\/     go test -filter=shortassign\/003     # Only run shortassign test #3\n\/\/\n\/\/ Refactorings are run on the files in each test directory; special comments\n\/\/ in the .go files indicate what refactoring(s) to run and whether the\n\/\/ refactorings are expected to succeed or fail.  Specifically, test files are\n\/\/ annotated with markers of the form\n\/\/     \/\/<<<<<name,startline,startcol,endline,endcol,arg1,arg2,...,argn,pass\n\/\/ The name indicates the refactoring to run.  The next four fields specify a\n\/\/ text selection on which to invoke the refactoring.  The arguments\n\/\/ arg1,arg2,...,argn are passed as arguments to the refactoring (see\n\/\/ Config.Args).  The last field is either \"pass\" or \"fail\", indicating whether\n\/\/ the refactoring is expected to complete successfully or raise an error.  If\n\/\/ the refactoring is expected to succeed, the resulting file is compared\n\/\/ against a .golden file with the same name in the same directory.\n\/\/\n\/\/ Each test directory (001-test-name, 002-test-name, etc.) is treated as the\n\/\/ root of a Go workspace when its tests are run; i.e., the GOPATH is set to\n\/\/ the test directory.  This allows it to define its own packages.  In such\n\/\/ cases, the test directory is usually structured as follows:\n\/\/\n\/\/     testdata\/\n\/\/         refactoring-name\/\n\/\/             001-test-name\/\n\/\/                 src\/\n\/\/                     main.go\n\/\/                     main.golden\n\/\/                     package-name\/\n\/\/                         package-file.go\n\/\/                         package-file.golden\n\/\/\n\/\/ To additional options are available and are currently used only to test the\n\/\/ Debug refactoring.  When it does not make sense to compare against a .golden\n\/\/ file, include an empty file named filename.golden.ignoreOutput instead.  If\n\/\/ the output will contain absolute paths to files in the test folder, include\n\/\/ a file named filename.go.stripPaths, and the refactoring's output will be\n\/\/ stripped of all occurrences of the absolute path to the .go file.\n\npackage refactoring_test\n\nimport

Where:\n\/\/\n\/\/   protocol   - driver name or alias (see below)\n\/\/   transport  - the transport protocol [tcp, udp, unix] (only mysql for now)\n\/\/   user       - the username to connect

(see the respective SQL driver for available options)\n\/\/\n\/\/ Example URLs for Open or Parse\n\/\/\n\/\/ The following are URLs that can be processed using Parse or Open:\n\/\/\n\/\/

documentation<commit_after>\/\/ Package dburl provides a standard, URL style mechanism for of parsing, and\n\/\/ opening database connection strings (in the form of a URL).\n\/\/\n\/\/ Database URL Connection Strings\n\/\/\n\/\/ Supported database URLs are of the form:\n\/\/\n\/\/   protocol+transport:\/\/user:pass@host\/dbname?opt1=a&opt2=b\n\/\/   protocol:\/path\/to\/file\n\/\/\n\/\/ Where:\n\/\/\n\/\/   protocol  - driver name or alias (see below)\n\/\/   transport - the transport protocol [tcp, udp, unix] (only mysql for now)\n\/\/   user      - the username to connect as\n\/\/   pass      - the password to use\n\/\/   host      - the remote host\n\/\/   dbname    - the database or service name to connect to\n\/\/   ?opt1=... - additional database driver options\n\/\/                 (see respective SQL driver for available options)\n\/\/\n\/\/ Example URLs for Open or Parse\n\/\/\n\/\/ The following are URLs that can be processed using Parse or Open:\n\/\/\n\/\/   postgres:\/\/user:pass@localhost\/dbname\n\/\/   pg:\/\/user:pass@localhost\/dbname?sslmode=disable\n\/\/   mysql:\/\/user:pass@localhost\/dbname\n\/\/   mysql:\/var\/run\/mysqld\/mysqld.sock\n\/\/

file:myfile.sqlite3?loc=auto\n\/\/\n\/\/ Parsing Rules\n\/\/\n\/\/ Parse relies heavily on the standard net\/url\/URL type, as such it has the\n\/\/ same parsing conventions\/semantics as any URL parsed by the standard\n\/\/ library's net\/url\/Parse.\n\/\/\n\/\/ SQL Driver Aliases\n\/\/\n\/\/ The following protocol aliases are available, and any URL passed to Open or\n\/\/ Parse will be processed the same as their respective driver:\n\/\/\n\/\/   Database (driver)            | Aliases\n\/\/   ------------------------------------------------------------------\n\/\/   Microsoft SQL

Workers will try to get a new work item\n\/\/ only if they have a working\/active connection. Workers without active connection\n\/\/ do not participate until a connection has been re-established.\n\/\/ Due to the pull based nature the algorithm will load-balance events by random\n\/\/ with workers having less latencies\/turn-around times potentially getting more\n\/\/ work items then other workers with higher latencies. Thusly the algorithm\n\/\/ dynamically adapts to resource availability of server events are forwarded to.\n\/\/\n\/\/ Workers not participating in the load-balancing will continuously try to reconnect\n\/\/ to their configured endpoints. Once a new connection has been established,\n\/\/ these workers will participate in in load-balancing again.\n\/\/\n\/\/ If a connection becomes unavailable, the events are rescheduled for another\n\/\/ connection to pick up. Rescheduling events is limited to a maximum number of\n\/\/ send attempts. If events have not been send after maximum number of allowed\n\/\/ attemps has been passed, they will be dropped.\n\/\/\n\/\/ Distributing events to workers is subject to timeout.

Workers will try to get a new work item\n\/\/ only if they have a working\/active connection. Workers without active connection\n\/\/ do not participate until a connection has been re-established.\n\/\/ Due to the pull based nature the algorithm will load-balance events by random\n\/\/ with workers having less latencies\/turn-around times potentially getting more\n\/\/ work items then other workers with higher latencies. Thusly the algorithm\n\/\/ dynamically adapts to resource availability of server events are forwarded to.\n\/\/\n\/\/ Workers not participating in the load-balancing will continuously try to reconnect\n\/\/ to their configured endpoints. Once a new connection has been established,\n\/\/ these workers will participate in in load-balancing again.\n\/\/\n\/\/ If a connection becomes unavailable, the events are rescheduled for another\n\/\/ connection to pick up. Rescheduling events is limited to a maximum number of\n\/\/ send attempts. If events have not been send after maximum number of allowed\n\/\/ attemps has been passed, they will be dropped.\n\/\/\n\/\/ Distributing events to workers is subject to timeout. If no worker is available to\n\/\/ pickup a message for sending, the message will be dropped internally.\ntype LoadBalancerMode struct {\n\ttimeout      time.Duration \/\/ Send\/retry timeout.

An Index can be created\n\/\/ using the New() and Open() methods.\n\/\/\n\/\/ Index() takes an input value, deduces a DocumentMapping for its type,\n\/\/ assigns string paths to its fields or values then applies field mappings on\n\/\/ them.\n\/\/\n\/\/ If the value is a []byte, the indexer attempts to convert it to something\n\/\/ else using the ByteArrayConverter registered as\n\/\/ IndexMapping.ByteArrayConverter. By default, it interprets the value as a\n\/\/ JSON payload and unmarshals it to map[string]interface{}.\n\/\/\n\/\/ The DocumentMapping used to index a value is deduced by the following rules:\n\/\/ 1) If value implements Classifier interface, resolve the mapping from Type().\n\/\/ 2) If value has a string field or value at IndexMapping.TypeField.\n\/\/ (defaulting to \"_type\"), use it to resolve the mapping. Fields addressing\n\/\/ is described below.\n\/\/ 3) If IndexMapping.DefaultType is registered, return it.\n\/\/ 4) Return IndexMapping.DefaultMapping.\n\/\/\n\/\/ Each field or nested field of the value is identified by a string path, then\n\/\/ mapped to one or several FieldMappings which extract the result for analysis.\n\/\/\n\/\/ Struct values fields are identified by their \"json:\" tag, or by their name.\n\/\/ Nested fields are identified by prefixing with their parent identifier,\n\/\/ separated by a dot.\n\/\/\n\/\/ Map values entries are identified by their string key. Entries not indexed\n\/\/ by strings are ignored. Entry values are identified recursively like struct\n\/\/ fields.\n\/\/\n\/\/ Slice and array values are identified by their field name. Their elements\n\/\/ are processed sequentially with the same FieldMapping.\n\/\/\n\/\/ String, float64 and time.Time values are identified by their field name.\n\/\/ Other types are ignored.\n\/\/\n\/\/ Each value identifier is decomposed in its parts and recursively address\n\/\/ SubDocumentMappings in the tree starting at the root DocumentMapping.  If a\n\/\/ mapping is found, all its FieldMappings are applied to the value. If no\n\/\/ mapping is found and the root DocumentMapping is dynamic, default mappings\n\/\/ are used based on value type and IndexMapping default configurations.\n\/\/\n\/\/ Finally, mapped values are analyzed, indexed or stored. Examples:\n\/\/\n\/\/  type Date struct {\n\/\/    Day string `json:\"day\"`\n\/\/    Month string\n\/\/    Year string\n\/\/  }\n\/\/\n\/\/  type Person struct {\n\/\/    FirstName string `json:\"first_name\"`\n\/\/    LastName string\n\/\/    BirthDate Date `json:\"birth_date\"`\n\/\/  }\n\/\/\n\/\/ A Person value FirstName is mapped by the SubDocumentMapping at\n\/\/ \"first_name\". Its LastName is mapped by the one at \"LastName\". The day of\n\/\/ BirthDate is mapped to the SubDocumentMapping \"day\" of the root\n\/\/ SubDocumentMapping \"birth_date\". It will appear as the \"birth_date.day\"\n\/\/ field in the index. The month is mapped to \"birth_date.Month\".\ntype Index interface {\n\t\/\/ Index analyzes, indexes or stores mapped data fields.

The other is\ncalled by the parser. These APIs are called the scanner and the parser APIs\nhere.\n\nThe parser API\n\nThe only function the parser calls on the lexer is Next to retreive the next\ntoken from the input stream.  Eventually an item with type ItemEOF is returned\nat which point there are no more tokens in the stream.\n\nThe scanner API\n\nThe lexer uses Emit to construct complete lexemes to return from\nfuture\/concurrent calls to Next by the parser.  The scanner uses a combination\nof methods to manipulate its position and and prepare lexemes to be emitted.\nLexer errors are emitted to the parser using the Errorf method which keeps the\nscanner-parser interface uniform.\n\nCommon lexer methods used in a scanner are the Accept[Run][Range] family of\nmethods.  Accept* methods take a set and advance the lexer if incoming runes\nare in the set. The AcceptRun* subfamily advance the lexer as far as possible.\n\nFor scanning known sequences of bytes (e.g. keywords) the AcceptString method\navoids a lot of branching that would be incurred using methods that match\ncharacter classes.\n\nThe remaining methods provide low level functionality that can be combined to\naddress corner cases.\n*\/\npackage lexer\n\nimport (\n\t\"container\/list\"\n\t\"fmt\"\n\t\"math\"\n\t\"strings\"\n\t\"unicode\"\n\t\"unicode\/utf8\"\n)\n\nconst EOF rune = 0x04\n\n\/\/ IsEOF returns true if n is zero.\nfunc IsEOF(c rune, n int) bool {\n\treturn n == 0\n}\n\n\/\/ IsInvalid returns true if c is utf8.RuneError and n is 1.\nfunc IsInvalid(c rune, n int) bool {\n\treturn c == utf8.RuneError && n == 1\n}\n\n\/\/ StateFn functions scan runes from the lexer's input and emit items.

Next has been renamed\nAdvance to be more idiomatic with Backup. Next is used by the parser to\nretrieve items from the lexer.\n\nTwo APIs\n\nThe Lexer type has two APIs, one is used byte StateFn types.  The other is\ncalled by the parser. These APIs are called the scanner and the parser APIs\nhere.\n\nThe parser API\n\nThe only function the parser calls on the lexer is Next to retreive the next\ntoken from the input stream.  Eventually an item with type ItemEOF is returned\nat which point there are no more tokens in the stream.\n\nThe scanner API\n\nThe lexer uses Emit to construct complete lexemes to return from\nfuture\/concurrent calls to Next by the parser.  The scanner uses a combination\nof methods to manipulate its position and and prepare lexemes to be emitted.\nLexer errors are emitted to the parser using the Errorf method which keeps the\nscanner-parser interface uniform.\n\nCommon lexer methods used in a scanner are the Accept[Run][Range] family of\nmethods.  Accept* methods take a set and advance the lexer if incoming runes\nare in the set. The AcceptRun* subfamily advance the lexer as far as possible.\n\nFor scanning known sequences of bytes (e.g. keywords) the AcceptString method\navoids a lot of branching that would be incurred using methods that match\ncharacter classes.\n\nThe remaining methods provide low level functionality that can be combined to\naddress corner cases.\n*\/\npackage lexer\n\nimport (\n\t\"container\/list\"\n\t\"fmt\"\n\t\"math\"\n\t\"strings\"\n\t\"unicode\"\n\t\"unicode\/utf8\"\n)\n\nconst EOF rune = 0x04\n\n\/\/ IsEOF returns true if n is zero.\nfunc IsEOF(c rune, n int) bool {\n\treturn n == 0\n}\n\n\/\/ IsInvalid returns true if c is utf8.RuneError and n is 1.\nfunc IsInvalid(c rune, n int) bool {\n\treturn c == utf8.RuneError && n == 1\n}\n\n\/\/ StateFn functions scan runes from the lexer's input and emit items.

It\ncan be used to read values from moon files, evaluate moon files to remove\nvariables, convert moon files to json where possible, and verify that a given\nmoon file is syntactically valid.\n\nThe following is taken to be the contents of a file named ex.moon:\n\n  # the whole document is implicitly a namespace, so you can set key value pairs\n  # at the top level.\n  first_name: \"jordan\"\n  last_name: \"orelli\"\n\n  # lists of things should be supported\n  items: [\n      \"one\"\n      2\n      3.4\n      [\"five\" 6 7.8]\n  ]\n\n  # objects should be supported\n  hash: {key: \"value\" other_key: \"other_value\"}\n\n  other_hash: {\n      key_1: \"one\"\n      key_2: 2\n      key_3: 3.4\n      key_4: [\"five\" 6 7.8]\n  }\n\n  # we may reference an item that was defined earlier\n  repeat_hash: hash\n\n  # items can be hidden.  i.e., they're only valid in the parse and eval stage as\n  # intermediate values internal to the config file; they are *not* visible to\n  # the host program.  This is generally useful for composing larger, more\n  # complicated things.\n  .hidden_item: \"it has a value\"\n\n  visible_item: .hidden_item\n\n  .person_one: {\n      name: \"the first name here\"\n      age: 28\n      hometown: \"crooklyn\"\n  }\n\n  .person_two: {\n      name: \"the second name here\"\n      age: 30\n      hometown: \"tha bronx\"\n  }\n\n  people: [.person_one .person_two]\n\n\nSubcommands\n\ncheck:  used to syntax check a given file.  To check a given file, in this case ex.moon, to see if it is syntactically valid, one would invoke the following command:\n\n  moon check ex.moon\n\nIf the file is syntactically valid, moon will print nothing and exit with a\nstatus of 0.  If the file is invalid, moon will print a cryptic error message\nthat won't help you fix the file and exit with a status of 1.\n\neval:  evaluates a given moon file.  The file is parsed and evaluated, and its result is printed on stdout, itself in the moon format.  Invoking the following command:\n\n  moon eval ex.moon\n\nwould produce the following output:\n\n  first_name: \"jordan\"\n  items: [\"one\" 2 3.4 [\"five\" 6 7.8]]\n  other_hash: {key_3: 3.4 key_4: [\"five\" 6 7.8] key_1: \"one\" key_2: 2}\n  repeat_hash: {key: \"value\" other_key: \"other_value\"}\n  people: [{age: 28 hometown: \"crooklyn\" name: \"the first name here\"} {hometown: \"tha bronx\" name: \"the second name here\" age: 30}]\n  last_name: \"orelli\"\n  hash: {key: \"value\" other_key: \"other_value\"}\n  visible_item: \"it has a value\"\n\nto:  used to convert moon files to other formats.  Right now, the only\nsupported format is json.  To convert a given moon file to json, one would invoke the following command:\n\n  moon to json ex.moon\n\nIf the file is valid and can be converted to json (i.e., only involves types\nthat are also supported by json or readily convertible to json types), the\nfile's json representation will be printed on stdout.\n\nThe \"to\" subcommand can also take its input from stdin by omitting a file name, as in one of the following invocations:\n\n  cat ex.moon | moon to json\n  moon to json < ex.moon\n\nEither invocation would have the same effect.\n\nget:  evaluates a moon file and retrieves a value, printing it on stdout out.\nThe file is parsed and evaluated, meaning that get will fail if executed\nagainst an invalid moon file; this is a search on an evaluated moon document,\nnot a textual search.  The general format of invocation is as follows:\n\n  moon get $search_term $file\n\nWhere $search_term refers to a key or a path, and $file refers to the name of a\nfile to be searched.

{"text":"<commit_before>\/*\nPackage bloom provides data structures and methods for creating Bloom filters.\n\nA Bloom filter is a representation of a set of _n_ items, where the main\nrequirement is to make membership queries; _i.e._, whether an item is a\nmember of a set.\n\nA Bloom filter has two parameters: _m_, a maximum size (typically a reasonably large\nmultiple of the cardinality of the set to represent) and _k_, the number of hashing\nfunctions on elements of the set. (The actual hashing functions are important, too,\nbut this is not a parameter for this implementation). A Bloom filter is backed by\na BitSet; a key is represented in the filter by setting the bits at each value of the\nhashing functions (modulo _m_). Set membership is done by _testing_ whether the\nbits at each value of the hashing functions (again, modulo _m_) are set. If so,\nthe item is in the set. If the item is actually in the set, a Bloom filter will\nnever fail (the true positive rate is 1.0); but it is susceptible to false\npositives. The art is to choose _k_ and _m_ correctly.\n\nIn this implementation, the hashing functions used is a local version of FNV,\na non-cryptographic hashing function, seeded with the index number of\nthe kth hashing function.\n\nThis implementation accepts keys for setting as testing as []byte. Thus, to\nadd a string item, \"Love\":\n\n    uint n = 1000\n    filter := bloom.New(20*n, 5) \/\/ load of 20, 5 keys\n    filter.Add([]byte(\"Love\"))\n\nSimilarly, to test if \"Love\" is in bloom:\n\n    if filter.Test([]byte(\"Love\"))\n\nFor numeric data, I recommend that you look into the binary\/encoding library. But,\nfor example, to add a uint32 to the filter:\n\n    i := uint32(100)\n    n1 := make([]byte,4)\n    binary.BigEndian.PutUint32(n1,i)\n    f.Add(n1)\n\nFinally, there is a method to estimate the false positive rate of a particular\nBloom filter for a set of size _n_:\n\n    if filter.EstimateFalsePositiveRate(1000) > 0.001\n\nGiven the particular hashing scheme, it's best to be empirical about this.

Thus, to\nadd a string item, \"Love\":\n\n    uint n = 1000\n    filter := bloom.New(20*n, 5) \/\/ load of 20, 5 keys\n    filter.Add([]byte(\"Love\"))\n\nSimilarly, to test if \"Love\" is in bloom:\n\n    if filter.Test([]byte(\"Love\"))\n\nFor numeric data, I recommend that you look into the binary\/encoding library. But,\nfor example, to add a uint32 to the filter:\n\n    i := uint32(100)\n    n1 := make([]byte,4)\n    binary.BigEndian.PutUint32(n1,i)\n    f.Add(n1)\n\nFinally, there is a method to estimate the false positive rate of a particular\nBloom filter for a set of size _n_:\n\n    if filter.EstimateFalsePositiveRate(1000) > 0.001\n\nGiven the particular hashing scheme, it's best to be empirical about this. Note\nthat estimating the FP rate will clear the Bloom filter.\n*\/\npackage bloom\n\nimport (\n\t\"bytes\"\n\t\"encoding\/binary\"\n\t\"encoding\/json\"\n\t\"fmt\"\n\t\"io\"\n\t\"math\"\n\n\t\"github.com\/spaolacci\/murmur3\"\n\t\"github.com\/willf\/bitset\"\n)\n\n\/\/ A BloomFilter is a representation of a set of _n_ items, where the main\n\/\/ requirement is to make membership queries; _i.e._, whether an item is a\n\/\/ member of a set.\ntype BloomFilter struct {\n\tm uint\n\tk uint\n\tb *bitset.BitSet\n}\n\n\/\/ New creates a new Bloom filter with _m_ bits and _k_ hashing functions\nfunc New(m uint, k uint) *BloomFilter {\n\treturn &BloomFilter{m, k, bitset.New(m)}\n}\n\n\/\/ From creates a new Bloom filter with len(_data_) * 64 bits and _k_ hashing\n\/\/ functions.

Also changes the test to make sure node is indeed ready after Kubelet restart. The previous readiness check may use old API state but didn't run into the issue due to the delay of waiting for pod restart.<commit_after>\/*\nCopyright 2017 The Kubernetes Authors.\n\nLicensed under

You can rollback to any previous deployment, or even scale multiple\ndeployments up at the same time.\n\nThere are several deployment strategies defined:\n\n* Rolling (default) - scales up the new deployment in stages, gradually reducing the number\n  of old deployments. If one of the new deployed pods never becomes \"ready\", the new deployment\n  will be rolled back (scaled down to zero). Use when your application can tolerate two versions\n  of code running at the same time (many web applications, scalable databases)\n* Recreate - scales the old deployment down to zero, then scales the new deployment up to full.\n  Use when your application cannot tolerate two versions of code running at the same time\n* Custom - run your own deployment process inside a Docker container using your own scripts.\n\nIf a deployment fails, you may opt to retry it (if the error was transient). Some deployments may\nnever successfully complete - in which case you can use the '--latest' flag to force a redeployment.\nWhen rolling back to a previous deployment, a new deployment will be created with an identical copy\nof your config at the latest position.\n\nIf you want to cancel a running deployment, use '--cancel' but keep in mind that this is a best-effort\noperation and may take some time to complete. It’s possible the deployment will partially or totally\ncomplete before the cancellation is effective.

Each individual deployment is exposed\nas a new replication controller, and the deployment process manages scaling down old deployments\nand scaling up new ones. Use '%[1]s rollback' to rollback to any previous deployment.\n\nThere are several deployment strategies defined:\n\n* Rolling (default) - scales up the new deployment in stages, gradually reducing the number\n  of old deployments. If one of the new deployed pods never becomes \"ready\", the new deployment\n  will be rolled back (scaled down to zero). Use when your application can tolerate two versions\n  of code running at the same time (many web applications, scalable databases)\n* Recreate - scales the old deployment down to zero, then scales the new deployment up to full.\n  Use when your application cannot tolerate two versions of code running at the same time\n* Custom - run your own deployment process inside a Docker container using your own scripts.\n\nIf a deployment fails, you may opt to retry it (if the error was transient). Some deployments may\nnever successfully complete - in which case you can use the '--latest' flag to force a redeployment.\nIf a deployment config has completed deploying successfully at least once in the past, it would be\nautomatically rolled back in the event of a new failed deployment. Note that you would still need\nto update the erroneous deployment config in order to have its template persisted across your\napplication.\n\nIf you want to cancel a running deployment, use '--cancel' but keep in mind that this is a best-effort\noperation and may take some time to complete. It’s possible the deployment will partially or totally\ncomplete before the cancellation is effective.

Event\n\/\/ ports are level-triggered, unlike epoll and kqueue which\n\/\/ can be configured in both level-triggered and edge-triggered\n\/\/ mode. Level triggering means we have to keep track of a few things\n\/\/ ourselves. After we receive an event for a file descriptor,\n\/\/ it's our responsibility to ask again to be notified for future\n\/\/ events for that descriptor. When doing this we must keep track of\n\/\/ what kind of events the goroutines are currently interested in,\n\/\/ for example a fd may be open both for reading and writing.\n\/\/\n\/\/ A description of the high level operation of this code\n\/\/ follows. Networking code will get a file descriptor by some means\n\/\/ and will register it with the netpolling mechanism by a code path\n\/\/ that eventually calls runtime·netpollopen. runtime·netpollopen\n\/\/ calls port_associate with an empty event set. That means that we\n\/\/ will not receive any events at this point. The association needs\n\/\/ to be done at this early point because we need to process the I\/O\n\/\/ readiness notification at some point in the future. If I\/O becomes\n\/\/ ready when nobody is listening, when we finally care about it,\n\/\/ nobody will tell us anymore.\n\/\/\n\/\/ Beside calling runtime·netpollopen, the networking code paths\n\/\/ will call runtime·netpollarm each time goroutines are interested\n\/\/ in doing network I\/O. Because now we know what kind of I\/O we\n\/\/ are interested in (reading\/writing), we can call port_associate\n\/\/ passing the correct type of event set (POLLIN\/POLLOUT). As we made\n\/\/ sure to have already associated the file descriptor with the port,\n\/\/ when we now call port_associate, we will unblock the main poller\n\/\/ loop (in runtime·netpoll) right away if the socket is actually\n\/\/ ready for I\/O.\n\/\/\n\/\/ The main poller loop runs in its own thread waiting for events\n\/\/ using port_getn. When an event happens, it will tell the scheduler\n\/\/ about it using runtime·netpollready. Besides doing this, it must\n\/\/ also re-associate the events that were not part of this current\n\/\/ notification with the file descriptor. Failing to do this would\n\/\/ mean each notification will prevent concurrent code using the\n\/\/ same file descriptor in parallel.\n\/\/\n\/\/ The logic dealing with re-associations is encapsulated in\n\/\/ runtime·netpollupdate. This function takes care to associate the\n\/\/ descriptor only with the subset of events that were previously\n\/\/ part of the association, except the one that just happened. We\n\/\/ can't re-associate with that right away, because event ports\n\/\/ are level triggered so it would cause a busy loop. Instead, that\n\/\/ association is effected only by the runtime·netpollarm code path,\n\/\/ when Go code actually asks for I\/O.\n\/\/\n\/\/ The open and arming mechanisms are serialized using the lock\n\/\/ inside PollDesc. This is required because the netpoll loop runs\n\/\/ asynchronously in respect to other Go code and by the time we get\n\/\/ to call port_associate to update the association in the loop, the\n\/\/ file descriptor might have been closed and reopened already. The\n\/\/ lock allows runtime·netpollupdate to be called synchronously from\n\/\/ the loop thread while preventing other threads operating to the\n\/\/ same PollDesc, so once we unblock in the main loop, until we loop\n\/\/ again we know for sure we are always talking about the same file\n\/\/ descriptor and can safely access the data we want (the event set).\n\n\/\/go:cgo_import_dynamic libc_port_create port_create \"libc.so\"\n\/\/go:cgo_import_dynamic libc_port_associate port_associate \"libc.so\"\n\/\/go:cgo_import_dynamic libc_port_dissociate port_dissociate \"libc.so\"\n\/\/go:cgo_import_dynamic libc_port_getn port_getn \"libc.so\"\n\/\/go:cgo_import_dynamic libc_port_alert port_alert \"libc.so\"\n\n\/\/go:linkname libc_port_create libc_port_create\n\/\/go:linkname libc_port_associate libc_port_associate\n\/\/go:linkname libc_port_dissociate libc_port_dissociate\n\/\/go:linkname libc_port_getn libc_port_getn\n\/\/go:linkname libc_port_alert libc_port_alert\n\nvar (\n\tlibc_port_create,\n\tlibc_port_associate,\n\tlibc_port_dissociate,\n\tlibc_port_getn,\n\tlibc_port_alert libcFunc\n)\n\nfunc errno() int32 {\n\treturn *getg().m.perrno\n}\n\nfunc fcntl(fd, cmd, arg int32) int32 {\n\treturn int32(sysvicall3(&libc_fcntl, uintptr(fd), uintptr(cmd), uintptr(arg)))\n}\n\nfunc port_create() int32 {\n\treturn int32(sysvicall0(&libc_port_create))\n}\n\nfunc port_associate(port, source int32, object uintptr, events uint32, user uintptr) int32 {\n\treturn int32(sysvicall5(&libc_port_associate, uintptr(port), uintptr(source), object, uintptr(events), user))\n}\n\nfunc port_dissociate(port, source int32, object uintptr) int32 {\n\treturn int32(sysvicall3(&libc_port_dissociate, uintptr(port), uintptr(source), object))\n}\n\nfunc port_getn(port int32, evs *portevent, max uint32, nget *uint32, timeout *timespec) int32 {\n\treturn int32(sysvicall5(&libc_port_getn, uintptr(port), uintptr(unsafe.Pointer(evs)), uintptr(max), uintptr(unsafe.Pointer(nget)), uintptr(unsafe.Pointer(timeout))))\n}\n\nfunc port_alert(port int32, flags, events uint32, user uintptr) int32 {\n\treturn int32(sysvicall4(&libc_port_alert, uintptr(port), uintptr(flags), uintptr(events), user))\n}\n\nvar portfd int32 = -1\n\nfunc netpollinit() {\n\tportfd = port_create()\n\tif portfd >= 0 {\n\t\tfcntl(portfd, _F_SETFD, _FD_CLOEXEC)\n\t\treturn\n\t}\n\n\tprint(\"runtime: port_create failed (errno=\", errno(), \")\\n\")\n\tthrow(\"runtime: netpollinit failed\")\n}\n\nfunc netpollIsPollDescriptor(fd uintptr) bool {\n\treturn fd == uintptr(portfd)\n}\n\nfunc netpollopen(fd uintptr, pd *pollDesc) int32 {\n\tlock(&pd.lock)\n\t\/\/ We don't register for any specific type of events yet, that's\n\t\/\/ netpollarm's job.

Because now we know what kind of I\/O we\n\/\/ are interested in (reading\/writing), we can call port_associate\n\/\/ passing the correct type of event set (POLLIN\/POLLOUT). As we made\n\/\/ sure to have already associated the file descriptor with the port,\n\/\/ when we now call port_associate, we will unblock the main poller\n\/\/ loop (in runtime·netpoll) right away if the socket is actually\n\/\/ ready for I\/O.\n\/\/\n\/\/ The main poller loop runs in its own thread waiting for events\n\/\/ using port_getn. When an event happens, it will tell the scheduler\n\/\/ about it using runtime·netpollready. Besides doing this, it must\n\/\/ also re-associate the events that were not part of this current\n\/\/ notification with the file descriptor. Failing to do this would\n\/\/ mean each notification will prevent concurrent code using the\n\/\/ same file descriptor in parallel.\n\/\/\n\/\/ The logic dealing with re-associations is encapsulated in\n\/\/ runtime·netpollupdate. This function takes care to associate the\n\/\/ descriptor only with the subset of events that were previously\n\/\/ part of the association, except the one that just happened. We\n\/\/ can't re-associate with that right away, because event ports\n\/\/ are level triggered so it would cause a busy loop. Instead, that\n\/\/ association is effected only by the runtime·netpollarm code path,\n\/\/ when Go code actually asks for I\/O.\n\/\/\n\/\/ The open and arming mechanisms are serialized using the lock\n\/\/ inside PollDesc. This is required because the netpoll loop runs\n\/\/ asynchronously in respect to other Go code and by the time we get\n\/\/ to call port_associate to update the association in the loop, the\n\/\/ file descriptor might have been closed and reopened already. The\n\/\/ lock allows runtime·netpollupdate to be called synchronously from\n\/\/ the loop thread while preventing other threads operating to the\n\/\/ same PollDesc, so once we unblock in the main loop, until we loop\n\/\/ again we know for sure we are always talking about the same file\n\/\/ descriptor and can safely access the data we want (the event set).\n\n\/\/go:cgo_import_dynamic libc_port_create port_create \"libc.so\"\n\/\/go:cgo_import_dynamic libc_port_associate port_associate \"libc.so\"\n\/\/go:cgo_import_dynamic libc_port_dissociate port_dissociate \"libc.so\"\n\/\/go:cgo_import_dynamic libc_port_getn port_getn \"libc.so\"\n\/\/go:cgo_import_dynamic libc_port_alert port_alert \"libc.so\"\n\n\/\/go:linkname libc_port_create libc_port_create\n\/\/go:linkname libc_port_associate libc_port_associate\n\/\/go:linkname libc_port_dissociate libc_port_dissociate\n\/\/go:linkname libc_port_getn libc_port_getn\n\/\/go:linkname libc_port_alert libc_port_alert\n\nvar (\n\tlibc_port_create,\n\tlibc_port_associate,\n\tlibc_port_dissociate,\n\tlibc_port_getn,\n\tlibc_port_alert libcFunc\n)\n\nfunc errno() int32 {\n\treturn *getg().m.perrno\n}\n\nfunc fcntl(fd, cmd, arg int32) int32 {\n\treturn int32(sysvicall3(&libc_fcntl, uintptr(fd), uintptr(cmd), uintptr(arg)))\n}\n\nfunc port_create() int32 {\n\treturn int32(sysvicall0(&libc_port_create))\n}\n\nfunc port_associate(port, source int32, object uintptr, events uint32, user uintptr) int32 {\n\treturn int32(sysvicall5(&libc_port_associate, uintptr(port), uintptr(source), object, uintptr(events), user))\n}\n\nfunc port_dissociate(port, source int32, object uintptr) int32 {\n\treturn int32(sysvicall3(&libc_port_dissociate, uintptr(port), uintptr(source), object))\n}\n\nfunc port_getn(port int32, evs *portevent, max uint32, nget *uint32, timeout *timespec) int32 {\n\treturn int32(sysvicall5(&libc_port_getn, uintptr(port), uintptr(unsafe.Pointer(evs)), uintptr(max), uintptr(unsafe.Pointer(nget)), uintptr(unsafe.Pointer(timeout))))\n}\n\nfunc port_alert(port int32, flags, events uint32, user uintptr) int32 {\n\treturn int32(sysvicall4(&libc_port_alert, uintptr(port), uintptr(flags), uintptr(events), user))\n}\n\nvar portfd int32 = -1\n\nfunc netpollinit() {\n\tportfd = port_create()\n\tif portfd >= 0 {\n\t\tfcntl(portfd, _F_SETFD, _FD_CLOEXEC)\n\t\treturn\n\t}\n\n\tprint(\"runtime: port_create failed (errno=\", errno(), \")\\n\")\n\tthrow(\"runtime: netpollinit failed\")\n}\n\nfunc netpollIsPollDescriptor(fd uintptr) bool {\n\treturn fd == uintptr(portfd)\n}\n\nfunc netpollopen(fd uintptr, pd *pollDesc) int32 {\n\tlock(&pd.lock)\n\t\/\/ We don't register for any specific type of events yet, that's\n\t\/\/ netpollarm's job.

Think of it is as the brain that is inserted into the\n\/\/robot shell of GameManager to imbue it with life. Typically your package\n\/\/that defines your game will have one public entrypoint, which is to return a\n\/\/GameDelegate for that packge. All logic specific to your game is configured\n\/\/via the return values of various methods in your GameDelegate. Your\n\/\/GameDelegate defines configuration for the type of game in general (via\n\/\/Configure* methods), as well as lifecycle methods for specific games (e.g.\n\/\/DistributeComponentToStarterStack). base.GameDelegate is a useful base\n\/\/struct to embed in your own GameDelegate, providing reasonable default\n\/\/behavior for nearly every method in GameDelegate.\ntype GameDelegate interface {\n\n\t\/\/Name is a string that defines the type of game this is. This must return\n\t\/\/the package name that contains the game (e.g.\n\t\/\/\"github.com\/jkomoros\/mygame\" should return \"mygame\"), since the package\n\t\/\/name and the delegate.Name() are both used at different times in the\n\t\/\/system, since one can be determined statically and the other only at\n\t\/\/run-time. NewGameManager will fail if that is not true.The name should\n\t\/\/be unique and compact since it will sometimes be used in a URL path.\n\t\/\/Good examples are \"tictactoe\", \"blackjack\". Once configured, names\n\t\/\/should never change over the lifetime of the gametype, since it will be\n\t\/\/persisted in storage.\n\tName() string\n\n\t\/\/DisplayName is a string that defines the type of game this is in a way\n\t\/\/appropriate for humans. The name should be unique but human readable. It\n\t\/\/is purely for human consumption, and may change over time with no\n\t\/\/adverse effects. Good examples are \"Tic Tac Toe\", \"Blackjack\".\n\t\/\/Subclasses should override this.\n\tDisplayName() string\n\n\t\/\/Description is a string that describes the game type in a descriptive\n\t\/\/sentence, for use in showing to end users. A reasonable value for\n\t\/\/\"tictactoe\" is \"A classic game where players compete to get three in a\n\t\/\/row\"\n\tDescription() string\n\n\t\/\/ConfigureMoves will be called during creation of a GameManager in\n\t\/\/NewGameManager. This is the time to install moves onto the manager by\n\t\/\/returning a list of moves to install. This is the single most important\n\t\/\/configuration point for your game logic, as the collection of moves for\n\t\/\/the game--and the logic of when they apply--is the bedrock of your game\n\t\/\/logic. Typically you use moves.Combine and friends to organize your list\n\t\/\/of moves to install. If the moves you add are illegal for any reason,\n\t\/\/NewGameManager will fail with an error. By the time this is called.\n\t\/\/delegate.SetManager will already have been called, so you'll have access\n\t\/\/to the manager via Manager().\n\tConfigureMoves() []MoveConfig\n\n\t\/\/ConfigureAgents will be called when creating a new GameManager. Emit the\n\t\/\/agents you want to install.\n\tConfigureAgents() []Agent\n\n\t\/\/ConfigureDecks will be called when the GameManager is being booted up.\n\t\/\/Each entry in the return value will be added to the ComponentChest that\n\t\/\/is being created for this game type. This method is where you create\n\t\/\/individual decks via NewDeck and associate the right underlying\n\t\/\/ComponentValues with each component via AddComponent.\n\tConfigureDecks() map[string]*Deck\n\n\t\/\/ConfigureEnums is called during set up of a new GameManager. Return the\n\t\/\/set of enums you want to be associated with this GameManagaer's Chest.\n\t\/\/`boardgame-util codegen` will often generate this automatically for you.\n\tConfigureEnums() *enum.Set\n\n\t\/\/ConfigureConstants is called during set-up of a new GameManager. Return\n\t\/\/the map of constants you want to create, which will be configured onto\n\t\/\/the newly created chest. If any of the constants cannot be added to the\n\t\/\/ComponentChest, errors, the GameManager will fail to be set up.\n\t\/\/Constants are primarily useful in two cases: first, when you want to\n\t\/\/have access to a constant value client-side, and second, when you want\n\t\/\/to be able to use a constant value in a struct tag provided as an\n\t\/\/instruction for a StructInflater.\n\tConfigureConstants() PropertyCollection\n\n\t\/\/GameStateConstructor and PlayerStateConstructor are called to get an\n\t\/\/instantiation of the concrete game\/player structs that your package\n\t\/\/defines. This is used both to create the initial state, but also to\n\t\/\/inflate states from the database. These methods should always return the\n\t\/\/underlying same type of struct when called. This means that if different\n\t\/\/players have very different roles in a game, there might be many\n\t\/\/properties that are not in use for any given player. The simple\n\t\/\/properties (ints, bools, strings) should all be their zero-value.\n\t\/\/Importantly, all Stacks, Timers, and Enums should be non- nil, because\n\t\/\/an initialized struct contains information about things like MaxSize,\n\t\/\/Size, and a reference to the deck they are affiliated with. GameManger\n\t\/\/will automatically create and use StructInflaters for these types of\n\t\/\/objects, allowing you to use tag-based configuration to automatically\n\t\/\/inflate these properties. See the documentation for StructInflater for\n\t\/\/more.\n\tGameStateConstructor() ConfigurableSubState\n\t\/\/PlayerStateConstructor is similar to GameStateConstructor, but\n\t\/\/playerIndex is the value that this PlayerState must return when its\n\t\/\/PlayerIndex() is called.\n\tPlayerStateConstructor(player PlayerIndex) ConfigurablePlayerState\n\n\t\/\/DynamicComponentValuesConstructor returns an empty\n\t\/\/DynamicComponentValues for the given deck. DynamicComponentValues are\n\t\/\/useful for representing when a given component has mutable properties\n\t\/\/associated with it--for example, if a given card could have a stack of\n\t\/\/tokens on top, the stack of tokens would be a property on a\n\t\/\/DynamicComponentValues associated with that card component. If nil is\n\t\/\/returned, then the components in that deck don't have any dynamic\n\t\/\/component state. This method must always return the same underlying type\n\t\/\/of struct for the same deck. Like GameStateConstructor and\n\t\/\/PlayerStateConstructor, the engine will automatically create\n\t\/\/StructInflaters for these objects, allowing you to use tag-based\n\t\/\/inflation of properties. See StructInflate for more. If the returned\n\t\/\/object also implements the ComponentValues interface, then\n\t\/\/SetContainingComponent will be called on the DynamicComponent whenever\n\t\/\/one is created, with a reference back to the component it's associated\n\t\/\/with.\n\tDynamicComponentValuesConstructor(deck *Deck) ConfigurableSubState\n\n\t\/\/DistributeComponentToStarterStack is called during set up of a given\n\t\/\/Game to establish the Deck\/Stack invariant that every component in the\n\t\/\/chest is placed in precisely one Stack. Game will call this on each\n\t\/\/component in the Chest in order. This is where the logic goes to make\n\t\/\/sure each Component goes into its correct starter stack. You must return\n\t\/\/a non-nil Stack for each call, after which the given Component will be\n\t\/\/inserted into NextSlotIndex of that stack. If that is not the ordering\n\t\/\/you desire, you can fix it up in FinishSetUp by using SwapComponents. If\n\t\/\/any errors are returned, any nil Stacks are returned, or any returned\n\t\/\/stacks don't have space for another component, NewGame will fail and\n\t\/\/return an error. State and Component are only provided for reference; do\n\t\/\/not modify them.\n\tDistributeComponentToStarterStack(state ImmutableState, c Component) (ImmutableStack, error)\n\n\t\/\/BeginSetup is called on a newly created Game before components are\n\t\/\/distributed via DistributeComponentToStarterStack. If you need to modify\n\t\/\/your state before components are distributed, do it here. It is also\n\t\/\/where the variant configuration for your gametype will be passed (it\n\t\/\/will already have been checked for legality and had all configure\n\t\/\/defaults set), although you can also retrieve that at any time via\n\t\/\/game.Variant(). This is a good place to configure state that will be\n\t\/\/necessary for you to make the right decisions in\n\t\/\/DistributeComponentToStarterStack, or to transcribe config information\n\t\/\/you were passed into properties on your gameState as appropriate. If\n\t\/\/error is non-nil, Game setup will be aborted, with the reasoning\n\t\/\/including the error message provided.\n\tBeginSetUp(state State, variant Variant) error\n\n\t\/\/FinishSetUp is called during NewGame, *after* components have been\n\t\/\/distributed to their StarterStack. This is the last chance to modify the\n\t\/\/state before the game's initial state is considered final. For example,\n\t\/\/if you have a card game this is where you'd make sure the starter draw\n\t\/\/stacks are shuffled. If your game has multiple rounds, or if you don't\n\t\/\/want the game to start with it already set-up (e.g. you want to show\n\t\/\/animations of starter cards being dealt) then it's probably best to do\n\t\/\/most of the logic in a SetUp phase. See the README for more. If error is\n\t\/\/non-nil, Game setup will be aborted, with the reasoning including the\n\t\/\/error message provided.\n\tFinishSetUp(state State) error\n\n\t\/\/CheckGameFinished should return true if the game is finished, and who\n\t\/\/the winners are. Called after every move is applied.\n\tCheckGameFinished(state ImmutableState) (finished bool, winners []PlayerIndex)\n\n\t\/\/ProposeFixUpMove is called after a move has been applied. It may return\n\t\/\/a FixUp move, which will be applied before any other moves are applied.\n\t\/\/If it returns nil, we may take the next move off of the queue. FixUp\n\t\/\/moves are useful for things like shuffling a discard deck back into a\n\t\/\/draw deck, or other moves that are necessary to get the GameState back\n\t\/\/into reasonable shape. base.GameDelegate's defintion is almost always\n\t\/\/suficient.\n\tProposeFixUpMove(state ImmutableState) Move\n\n\t\/\/DefaultNumPlayers returns the number of users that new games of this\n\t\/\/type default to. For example, for tictactoe, it will be 2. If 0 is\n\t\/\/provided to manager.NewGame(), we wil use this value instead.\n\tDefaultNumPlayers() int\n\n\t\/\/Min\/MaxNumPlayers should return the min and max number of players,\n\t\/\/respectively. The engine doesn't use this directly, instead looking at\n\t\/\/LegalNumPlayers. Typically your LegalNumPlayers will check the given\n\t\/\/number of players is between these two extremes.\n\tMinNumPlayers() int\n\tMaxNumPlayers() int\n\n\t\/\/LegalNumPlayers will be consulted when a new game is created. It should\n\t\/\/return true if the given number of players is legal, and false\n\t\/\/otherwise. If this returns false, the NewGame will fail with an error.\n\t\/\/Game creation will automatically reject a numPlayers that does not\n\t\/\/result in at least one player existing. Generally this is simply\n\t\/\/checking to make sure the number of players is between Min and Max\n\t\/\/(inclusive), although some games could only allow, for example, even\n\t\/\/numbers of players.\n\tLegalNumPlayers(numPlayers int) bool\n\n\t\/\/Variants returns a VariantConfig, which describes the different\n\t\/\/categories of configuration values and the legal values they may take on\n\t\/\/when a new game is created. In general if you want to inspect legal\n\t\/\/variants in your own game logic you shouldn't call this, but instead\n\t\/\/call gameManager.Variants() which will ensure your VariantConfig is\n\t\/\/initalized and memoize the return result.\n\tVariants() VariantConfig\n\n\t\/\/CurrentPlayerIndex returns the index of the \"current\" player for the\n\t\/\/given game state--a notion that is game specific (and sometimes\n\t\/\/inapplicable). If CurrentPlayer doesn't make sense (perhaps the game\n\t\/\/never has a notion of current player, or the type of round that we're in\n\t\/\/has no current player), this should return ObserverPlayerIndex. The\n\t\/\/result of this method is used to power state.CurrentPlayer.\n\tCurrentPlayerIndex(state ImmutableState) PlayerIndex\n\n\t\/\/CurrentPhase returns the phase that the game state is currently in.\n\t\/\/Phase is a formalized convention used in moves.Default to make it easier\n\t\/\/to write fix-up moves that only apply in certain phases, like SetUp. The\n\t\/\/return result is primarily used in moves.Default to check whether it is\n\t\/\/one of the phases in a give Move's LegalPhases. See moves.Default for\n\t\/\/more information. The only use of this method in the main library is\n\t\/\/when generating a MoveStorageRecord.\n\tCurrentPhase(state ImmutableState) int\n\n\t\/\/PhaseEnum returns the enum for game phases (the return values of\n\t\/\/CurrentPhase are expected to be valid enums within that enum). If this\n\t\/\/returns a non-nil enums.TreeEnum, then the state will not be able to be\n\t\/\/saved if CurrentPhase() returns a value that is not a leaf-node. The\n\t\/\/core package doesn't rely on this method directly.\n\tPhaseEnum() enum.Enum\n\n\t\/\/SanitizationPolicy is consulted when sanitizing states. It is called for\n\t\/\/each prop in the state, including the set of groups that this player is\n\t\/\/a mamber of. In practice the default behavior of base.GameDelegate,\n\t\/\/which uses struct tags to figure out the policy, is sufficient and you\n\t\/\/do not need to override this. For more on how sanitization works, see\n\t\/\/the documenation for Policy. The statePropetyRef passed will always have\n\t\/\/the Index properties set to -1, signifying that the returned policy\n\t\/\/applies to all items in the Stack\/Board.\n\tSanitizationPolicy(prop StatePropertyRef, groupMembership map[int]bool) Policy\n\n\t\/\/If you have computed properties that you want to be included in your\n\t\/\/JSON (for example, for use clientside), export them here by creating a\n\t\/\/dictionary with their values.\n\tComputedGlobalProperties(state ImmutableState) PropertyCollection\n\tComputedPlayerProperties(player ImmutablePlayerState) PropertyCollection\n\n\t\/\/Diagram should return a basic debug rendering of state in multi-line\n\t\/\/ascii art.

This must return\n\t\/\/the package name that contains the game (e.g.\n\t\/\/\"github.com\/jkomoros\/mygame\" should return \"mygame\"), since the package\n\t\/\/name and the delegate.Name() are both used at different times in the\n\t\/\/system, since one can be determined statically and the other only at\n\t\/\/run-time. NewGameManager will fail if that is not true.The name should\n\t\/\/be unique and compact since it will sometimes be used in a URL path.\n\t\/\/Good examples are \"tictactoe\", \"blackjack\". Once configured, names\n\t\/\/should never change over the lifetime of the gametype, since it will be\n\t\/\/persisted in storage.\n\tName() string\n\n\t\/\/DisplayName is a string that defines the type of game this is in a way\n\t\/\/appropriate for humans. The name should be unique but human readable. It\n\t\/\/is purely for human consumption, and may change over time with no\n\t\/\/adverse effects. Good examples are \"Tic Tac Toe\", \"Blackjack\".\n\t\/\/Subclasses should override this.\n\tDisplayName() string\n\n\t\/\/Description is a string that describes the game type in a descriptive\n\t\/\/sentence, for use in showing to end users. A reasonable value for\n\t\/\/\"tictactoe\" is \"A classic game where players compete to get three in a\n\t\/\/row\"\n\tDescription() string\n\n\t\/\/ConfigureMoves will be called during creation of a GameManager in\n\t\/\/NewGameManager. This is the time to install moves onto the manager by\n\t\/\/returning a list of moves to install. This is the single most important\n\t\/\/configuration point for your game logic, as the collection of moves for\n\t\/\/the game--and the logic of when they apply--is the bedrock of your game\n\t\/\/logic. Typically you use moves.Combine and friends to organize your list\n\t\/\/of moves to install. If the moves you add are illegal for any reason,\n\t\/\/NewGameManager will fail with an error. By the time this is called.\n\t\/\/delegate.SetManager will already have been called, so you'll have access\n\t\/\/to the manager via Manager().\n\tConfigureMoves() []MoveConfig\n\n\t\/\/ConfigureAgents will be called when creating a new GameManager. Emit the\n\t\/\/agents you want to install.\n\tConfigureAgents() []Agent\n\n\t\/\/ConfigureDecks will be called when the GameManager is being booted up.\n\t\/\/Each entry in the return value will be added to the ComponentChest that\n\t\/\/is being created for this game type. This method is where you create\n\t\/\/individual decks via NewDeck and associate the right underlying\n\t\/\/ComponentValues with each component via AddComponent.\n\tConfigureDecks() map[string]*Deck\n\n\t\/\/ConfigureEnums is called during set up of a new GameManager. Return the\n\t\/\/set of enums you want to be associated with this GameManagaer's Chest.\n\t\/\/`boardgame-util codegen` will often generate this automatically for you.\n\tConfigureEnums() *enum.Set\n\n\t\/\/ConfigureConstants is called during set-up of a new GameManager. Return\n\t\/\/the map of constants you want to create, which will be configured onto\n\t\/\/the newly created chest. If any of the constants cannot be added to the\n\t\/\/ComponentChest, errors, the GameManager will fail to be set up.\n\t\/\/Constants are primarily useful in two cases: first, when you want to\n\t\/\/have access to a constant value client-side, and second, when you want\n\t\/\/to be able to use a constant value in a struct tag provided as an\n\t\/\/instruction for a StructInflater.\n\tConfigureConstants() PropertyCollection\n\n\t\/\/GameStateConstructor and PlayerStateConstructor are called to get an\n\t\/\/instantiation of the concrete game\/player structs that your package\n\t\/\/defines. This is used both to create the initial state, but also to\n\t\/\/inflate states from the database. These methods should always return the\n\t\/\/underlying same type of struct when called. This means that if different\n\t\/\/players have very different roles in a game, there might be many\n\t\/\/properties that are not in use for any given player. The simple\n\t\/\/properties (ints, bools, strings) should all be their zero-value.\n\t\/\/Importantly, all Stacks, Timers, and Enums should be non- nil, because\n\t\/\/an initialized struct contains information about things like MaxSize,\n\t\/\/Size, and a reference to the deck they are affiliated with. GameManger\n\t\/\/will automatically create and use StructInflaters for these types of\n\t\/\/objects, allowing you to use tag-based configuration to automatically\n\t\/\/inflate these properties. See the documentation for StructInflater for\n\t\/\/more.\n\tGameStateConstructor() ConfigurableSubState\n\t\/\/PlayerStateConstructor is similar to GameStateConstructor, but\n\t\/\/playerIndex is the value that this PlayerState must return when its\n\t\/\/PlayerIndex() is called.\n\tPlayerStateConstructor(player PlayerIndex) ConfigurablePlayerState\n\n\t\/\/DynamicComponentValuesConstructor returns an empty\n\t\/\/DynamicComponentValues for the given deck. DynamicComponentValues are\n\t\/\/useful for representing when a given component has mutable properties\n\t\/\/associated with it--for example, if a given card could have a stack of\n\t\/\/tokens on top, the stack of tokens would be a property on a\n\t\/\/DynamicComponentValues associated with that card component. If nil is\n\t\/\/returned, then the components in that deck don't have any dynamic\n\t\/\/component state. This method must always return the same underlying type\n\t\/\/of struct for the same deck. Like GameStateConstructor and\n\t\/\/PlayerStateConstructor, the engine will automatically create\n\t\/\/StructInflaters for these objects, allowing you to use tag-based\n\t\/\/inflation of properties. See StructInflate for more. If the returned\n\t\/\/object also implements the ComponentValues interface, then\n\t\/\/SetContainingComponent will be called on the DynamicComponent whenever\n\t\/\/one is created, with a reference back to the component it's associated\n\t\/\/with.\n\tDynamicComponentValuesConstructor(deck *Deck) ConfigurableSubState\n\n\t\/\/DistributeComponentToStarterStack is called during set up of a given\n\t\/\/Game to establish the Deck\/Stack invariant that every component in the\n\t\/\/chest is placed in precisely one Stack. Game will call this on each\n\t\/\/component in the Chest in order. This is where the logic goes to make\n\t\/\/sure each Component goes into its correct starter stack. You must return\n\t\/\/a non-nil Stack for each call, after which the given Component will be\n\t\/\/inserted into NextSlotIndex of that stack. If that is not the ordering\n\t\/\/you desire, you can fix it up in FinishSetUp by using SwapComponents. If\n\t\/\/any errors are returned, any nil Stacks are returned, or any returned\n\t\/\/stacks don't have space for another component, NewGame will fail and\n\t\/\/return an error. State and Component are only provided for reference; do\n\t\/\/not modify them.\n\tDistributeComponentToStarterStack(state ImmutableState, c Component) (ImmutableStack, error)\n\n\t\/\/BeginSetup is called on a newly created Game before components are\n\t\/\/distributed via DistributeComponentToStarterStack. If you need to modify\n\t\/\/your state before components are distributed, do it here. It is also\n\t\/\/where the variant configuration for your gametype will be passed (it\n\t\/\/will already have been checked for legality and had all configure\n\t\/\/defaults set), although you can also retrieve that at any time via\n\t\/\/game.Variant(). This is a good place to configure state that will be\n\t\/\/necessary for you to make the right decisions in\n\t\/\/DistributeComponentToStarterStack, or to transcribe config information\n\t\/\/you were passed into properties on your gameState as appropriate. If\n\t\/\/error is non-nil, Game setup will be aborted, with the reasoning\n\t\/\/including the error message provided.\n\tBeginSetUp(state State, variant Variant) error\n\n\t\/\/FinishSetUp is called during NewGame, *after* components have been\n\t\/\/distributed to their StarterStack. This is the last chance to modify the\n\t\/\/state before the game's initial state is considered final. For example,\n\t\/\/if you have a card game this is where you'd make sure the starter draw\n\t\/\/stacks are shuffled. If your game has multiple rounds, or if you don't\n\t\/\/want the game to start with it already set-up (e.g. you want to show\n\t\/\/animations of starter cards being dealt) then it's probably best to do\n\t\/\/most of the logic in a SetUp phase. See the README for more. If error is\n\t\/\/non-nil, Game setup will be aborted, with the reasoning including the\n\t\/\/error message provided.\n\tFinishSetUp(state State) error\n\n\t\/\/CheckGameFinished should return true if the game is finished, and who\n\t\/\/the winners are. Called after every move is applied.\n\tCheckGameFinished(state ImmutableState) (finished bool, winners []PlayerIndex)\n\n\t\/\/ProposeFixUpMove is called after a move has been applied. It may return\n\t\/\/a FixUp move, which will be applied before any other moves are applied.\n\t\/\/If it returns nil, we may take the next move off of the queue. FixUp\n\t\/\/moves are useful for things like shuffling a discard deck back into a\n\t\/\/draw deck, or other moves that are necessary to get the GameState back\n\t\/\/into reasonable shape. base.GameDelegate's defintion is almost always\n\t\/\/suficient.\n\tProposeFixUpMove(state ImmutableState) Move\n\n\t\/\/DefaultNumPlayers returns the number of users that new games of this\n\t\/\/type default to. For example, for tictactoe, it will be 2. If 0 is\n\t\/\/provided to manager.NewGame(), we wil use this value instead.\n\tDefaultNumPlayers() int\n\n\t\/\/Min\/MaxNumPlayers should return the min and max number of players,\n\t\/\/respectively. The engine doesn't use this directly, instead looking at\n\t\/\/LegalNumPlayers. Typically your LegalNumPlayers will check the given\n\t\/\/number of players is between these two extremes.\n\tMinNumPlayers() int\n\tMaxNumPlayers() int\n\n\t\/\/LegalNumPlayers will be consulted when a new game is created. It should\n\t\/\/return true if the given number of players is legal, and false\n\t\/\/otherwise. If this returns false, the NewGame will fail with an error.\n\t\/\/Game creation will automatically reject a numPlayers that does not\n\t\/\/result in at least one player existing. Generally this is simply\n\t\/\/checking to make sure the number of players is between Min and Max\n\t\/\/(inclusive), although some games could only allow, for example, even\n\t\/\/numbers of players.\n\tLegalNumPlayers(numPlayers int) bool\n\n\t\/\/Variants returns a VariantConfig, which describes the different\n\t\/\/categories of configuration values and the legal values they may take on\n\t\/\/when a new game is created. In general if you want to inspect legal\n\t\/\/variants in your own game logic you shouldn't call this, but instead\n\t\/\/call gameManager.Variants() which will ensure your VariantConfig is\n\t\/\/initalized and memoize the return result.\n\tVariants() VariantConfig\n\n\t\/\/CurrentPlayerIndex returns the index of the \"current\" player for the\n\t\/\/given game state--a notion that is game specific (and sometimes\n\t\/\/inapplicable). If CurrentPlayer doesn't make sense (perhaps the game\n\t\/\/never has a notion of current player, or the type of round that we're in\n\t\/\/has no current player), this should return ObserverPlayerIndex. The\n\t\/\/result of this method is used to power state.CurrentPlayer.\n\tCurrentPlayerIndex(state ImmutableState) PlayerIndex\n\n\t\/\/CurrentPhase returns the phase that the game state is currently in.\n\t\/\/Phase is a formalized convention used in moves.Default to make it easier\n\t\/\/to write fix-up moves that only apply in certain phases, like SetUp. The\n\t\/\/return result is primarily used in moves.Default to check whether it is\n\t\/\/one of the phases in a give Move's LegalPhases. See moves.Default for\n\t\/\/more information. The only use of this method in the main library is\n\t\/\/when generating a MoveStorageRecord.\n\tCurrentPhase(state ImmutableState) int\n\n\t\/\/PhaseEnum returns the enum for game phases (the return values of\n\t\/\/CurrentPhase are expected to be valid enums within that enum). If this\n\t\/\/returns a non-nil enums.TreeEnum, then the state will not be able to be\n\t\/\/saved if CurrentPhase() returns a value that is not a leaf-node. The\n\t\/\/core package doesn't rely on this method directly.\n\tPhaseEnum() enum.Enum\n\n\t\/\/SanitizationPolicy is consulted when sanitizing states. It is called for\n\t\/\/each prop in the state, including the set of groups that this player is\n\t\/\/a mamber of. In practice the default behavior of base.GameDelegate,\n\t\/\/which uses struct tags to figure out the policy, is sufficient and you\n\t\/\/do not need to override this. For more on how sanitization works, see\n\t\/\/the documenation for Policy. The statePropetyRef passed will always have\n\t\/\/the Index properties set to -1, signifying that the returned policy\n\t\/\/applies to all items in the Stack\/Board.\n\tSanitizationPolicy(prop StatePropertyRef, groupMembership map[int]bool) Policy\n\n\t\/\/If you have computed properties that you want to be included in your\n\t\/\/JSON (for example, for use clientside), export them here by creating a\n\t\/\/dictionary with their values.\n\tComputedGlobalProperties(state ImmutableState) PropertyCollection\n\tComputedPlayerProperties(player ImmutablePlayerState) PropertyCollection\n\n\t\/\/Diagram should return a basic debug rendering of state in multi-line\n\t\/\/ascii art. Useful for debugging. State.Diagram() will reach out to this\n\t\/\/method.\n\tDiagram(s ImmutableState) string\n\n\t\/\/SetManager configures which manager this delegate is in use with. A\n\t\/\/given delegate can only be used by a single manager at a time.\n\tSetManager(manager *GameManager)\n\n\t\/\/Manager returns the Manager that was set on this delegate.\n\tManager() *GameManager\n}\n\n\/\/PropertyCollection is just an alias for map[string]interface{}. It is used\n\/\/as the return value for a number of things, including\n\/\/GameDelegate.ConfigureConstants, and MoveConfig.CustomConfigration.\ntype PropertyCollection map[string]interface{}\n\n\/\/Copy returns a shallow copy of PropertyCollection\nfunc (p PropertyCollection) Copy() PropertyCollection {\n\tresult := make(PropertyCollection, len(p))\n\tfor key, val := range result {\n\t\tresult[key] = val\n\t}\n\treturn result\n}\n<|endoftext|>"}

{"text":"<commit_before>\/*\nGoat Latin is a made-up language based off of English, sort of like Pig Latin.\nThe rules of Goat Latin are as follows:\n\n1. If a word begins with a consonant (i.e. not a vowel), remove the first\nletter and append it to the end, then add 'ma'.\nFor example, the word 'goat' becomes 'oatgma'.\n\n2. If a word begins with a vowel, append 'ma' to the end of the word.\nFor example, the word 'I' becomes 'Ima'.\n\n3.

{"text":"<commit_before>\/\/ The `postgres` plugin for SHIELD is intended to be a generic\n\/\/ backup\/restore plugin for a postgres server. It can be used against\n\/\/ any postgres server compatible with the `psql` and `pg_dumpall` tools\n\/\/ installed on the system where this plugin is run.\n\/\/\n\/\/ PLUGIN FEATURES\n\/\/\n\/\/ This plugin implements functionality suitable for use with the following\n\/\/ SHIELD Job components:\n\/\/\n\/\/   Target: yes\n\/\/   Store:  no\n\/\/\n\/\/ PLUGIN CONFIGURATION\n\/\/\n\/\/ The endpoint configuration passed to this plugin is used to identify\n\/\/ what postgres instance to back up, and how to connect to it. Your\n\/\/ endpoint JSON should look something like this:\n\/\/\n\/\/    {\n\/\/        \"pg_user\":\"username-for-postgres\",\n\/\/        \"pg_password\":\"password-for-above-user\",\n\/\/        \"pg_host\":\"hostname-or-ip-of-pg-server\",\n\/\/        \"pg_port\":\"port-above-pg-server-listens-on\",   # optional, defaults to '5432'\n\/\/        \"pg_database\": \"name-of-db-to-backup\"          # optional, defaults to 'all'\n\/\/        \"pg_bindir\": \"PostgreSQL binaries directory\"   # optional, defaults to '\/var\/vcap\/packages\/postgres\/bin'\n\/\/    }\n\/\/\n\/\/ The `pg_port` field is optional. If specified, the plugin will connect to the\n\/\/ given port to perform backups. If not specified plugin will connect to\n\/\/ default postgres port 5432.\n\/\/\n\/\/ The `pg_database` field is optional.  If specified, the plugin will only\n\/\/ perform backups of the named database.  If not specified (the default), all\n\/\/ databases will be backed up.\n\/\/\n\/\/ The `pg_bindir` field is optional. It specifies where to find the PostgreSQL\n\/\/ binaries such as pg_dump \/ pg_dumpall \/ pg_restore. If specified, the plugin\n\/\/ will attempt to use binaries from within the given directory. If not specified\n\/\/ the plugin will default to trying to use binaries in\n\/\/ '\/var\/vcap\/packages\/postgres\/bin'.\n\/\/\n\/\/ BACKUP DETAILS\n\/\/\n\/\/ The `postgres` plugin makes use of `pg_dumpall -c` to back up all databases\n\/\/ on the postgres server it connects to. There is currently no filtering of\n\/\/ individual databases to back up, unless that is done via the postgres users\n\/\/ and roles. The dumps generated include SQL to clean up existing databses\/tables,\n\/\/ so that the restore will go smoothly.\n\/\/\n\/\/ Backing up with the `postgres` plugin will not drop any existing connections to the\n\/\/ database, or restart the service.\n\/\/\n\/\/ RESTORE DETAILS\n\/\/\n\/\/ To restore, the `postgres` plugin connects to the postgres server using the `psql`\n\/\/ command. It then feeds in the backup data (`pg_dumpall` output). To work around\n\/\/ cases where the databases being restored cannot be recreated due to existing connections,\n\/\/ the plugin disallows incoming connections for each database, and disconnects the existing\n\/\/ connections, prior to dropping the database. Once the database is recreated, connections\n\/\/ are once again allowed into the database.\n\/\/\n\/\/ Restoring with the `postgres` plugin will terminate existing connections to the database,\n\/\/ but does not need to restart the postgres service.\n\/\/\n\/\/ DEPENDENCIES\n\/\/\n\/\/ This plugin relies on the `pg_dumpall` and `psql` commands. Please ensure that they\n\/\/ are present on the system that will be running the backups + restores for postgres.\n\/\/ If you are using shield-boshrelease to deploy SHIELD, these tools are provided, if you\n\/\/ include the `agent-pgtools` job template along side your `shield-agent`.\n\/\/\npackage main\n\nimport

It also supports Graph API 2.0 using the same methods.\n\/\/\n\/\/ Library design is highly influenced by facebook official PHP\/JS SDK.\n\/\/ If you have used PHP\/JS SDK before, it should look quite familiar.\n\/\/\n\/\/ Here is a list of common scenarios to help you to get started.\n\/\/\n\/\/ Scenario 1: Read a graph `user` object without access token.\n\/\/     res, _ := facebook.Get(\"\/huandu\", nil)\n\/\/     fmt.Println(\"my facebook id is\", res[\"id\"])\n\/\/\n\/\/ Scenario 2: Read a graph `user` object with a valid access token.\n\/\/     res, _ := facebook.Get(\"\/me\/feed\", facebook.Params{\n\/\/          \"access_token\": \"a-valid-access-token\",\n\/\/     })\n\/\/\n\/\/     \/\/ read my last feed.\n\/\/     fmt.Println(\"my latest feed story is:\", res.Get(\"data.0.story\"))\n\/\/\n\/\/ Scenario 3: Use App and Session struct.

All rights reserved.\n\/\/ Use of this source code is governed by a MIT-style\n\/\/ license that can be found in the LICENSE file.\n\n\/\/ Package goserv provides a fast, easy and minimalistic framework for\n\/\/ web applications in Go.\n\/\/\n\/\/ Getting Started\n\/\/\n\/\/ Every goserv application starts with a single instance of goserv.Server. This\n\/\/ instance is the entry point for all incoming requests.\n\/\/\n\/\/      server := goserv.NewServer()\n\/\/\n\/\/ To start handling paths you must register handlers to paths using one of the Server's\n\/\/ embedded Router functions, like Get.\n\/\/\n\/\/      server.Get(\"\/\", homeHandler)\n\/\/\n\/\/ The first argument in the Get() call is the path for which the\n\/\/ handler gets registered. To learn more about paths take a look at the Path section.\n\/\/ As the name of the function suggests the requests are only getting dispatched to the handler\n\/\/ if the request method is \"GET\". There are a lot more methods like this one available, just take\n\/\/ a look at the documentation of the Router.\n\/\/\n\/\/ At this point it is worth noting that goserv provides it's own Handler type using the\n\/\/ goserv.ResponseWriter and goserv.Request. This means that all http.Handlers cannot\n\/\/ be used with goserv without wrapping them in a goserv.Handler. To make this more convenient\n\/\/ a function called WrapHTTPHandler exists.\n\/\/\n\/\/      server.Get(\"\/\", WrapHTTPHandler(httpHomeHandler))\n\/\/\n\/\/ Sometimes it is useful to have handlers that are invoked all the time, also known as middleware.\n\/\/ To register middleware use the Use() function.\n\/\/\n\/\/      server.Use(accessLogger)\n\/\/\n\/\/ Path Syntax\n\/\/\n\/\/ All Routes and Routers are registered under a path. This path is matched against the path\n\/\/ of incoming requests.\n\/\/\n\/\/ A Route created from \"\/mypath\" will only match the request path if it is exactly\n\/\/ \"\/mypath\".\n\/\/\n\/\/ In case that the Route should match everything starting with \"\/mypath\" a wildcard\n\/\/ can be appended to the path, i.e.\n\/\/\t\/mypath*\n\/\/\n\/\/ The wildcard can be at any position in the path. It also possible to just use the wildcard\n\/\/ as path.\n\/\/\n\/\/ Sometimes it is necessary to capture values from parts of the request path, so called parameters.\n\/\/ To include parameters in a Route the path must contain a named parameter, e.g.\n\/\/\t\/users\/:user_id\n\/\/\n\/\/ Parameters always start with a \":\" after a \"\/\". The name (without the leading \":\") can contain\n\/\/ alphanumeric symbols as well as \"_\" and \"-\". The number of parameters in a Route is not limited, but\n\/\/ they must be separated by at least a single \"\/\".\n\/\/\t\/:value1\/:value2\n\/\/\n\/\/ Routers allow you to register handlers for each parameter in a Route. Each handler gets invoked\n\/\/ once per parameter and request. That means even though a Router may invoked multiple Routes the\n\/\/ parameter handlers are invoked only once.\n\/\/\n\/\/      router.Get(\"\/users\/:user_id\", handler)\n\/\/      router.Param(\"user_id\", userIDHandler)\n\/\/\n\/\/ When a Route processes a Request it automatically extracts the captured parameter values from the path\n\/\/ and stores the values under their name in the .Param field of the Request.\n\/\/\n\/\/ Strict vs non-strict Slash\n\/\/\n\/\/ A Route can have either strict slash or non-strict slash behavior. In non-strict mode paths with or\n\/\/ without a trailing slash are considered to be the same, i.e. a Route registered with \"\/mypath\" in\n\/\/ non-strict mode matches both \"\/mypath\" and \"\/mypath\/\". In strict mode both\n\/\/ paths are considered to be different.\n\/\/\n\/\/ Order matters\n\/\/\n\/\/ The order in which Handlers are registered does matter. An incoming request goes through in the\n\/\/ exact same order. After each handler the Router checks wether an error was set on the\n\/\/ ResponseWriter or if a response was written and ends the processing if necessary. In case of an error\n\/\/ the Router forwards the request along with the error to its ErrorHandler, but only if one is available.\n\/\/ All sub Routers have no ErrorHandler by default, so all errors are handled by the top level Server. It\n\/\/ is possible though to handle errors in a sub Router by setting a custom ErrorHandler.\n\/\/\n\/\/ A small example shows how requests are processed in a Router:\n\/\/\n\/\/      server.Use(A)\n\/\/      server.Get(\"\/\", B)\n\/\/      server.Use(C)\n\/\/      server.SubRouter(\"\/sub\", D)\n\/\/\n\/\/ All incoming request will follow the order \"ABCD\".

{"text":"<commit_before>\/\/ Licensed under the MIT license, see LICENCE file for details.\n\n\/*\nPackage quicktest provides a collection of Go helpers for writing tests.\n\nQuicktest helpers can be easily integrated inside regular Go tests, for\ninstance:\n\n    import qt \"github.com\/frankban\/quicktest\"\n\n    func TestFoo(t *testing.T) {\n        t.Run(\"numbers\", func(t *testing.T) {\n            c := qt.New(t)\n            numbers, err := somepackage.Numbers()\n            c.Assert(numbers, qt.DeepEquals, []int{42, 47})\n            c.Assert(err, qt.ErrorMatches, \"bad wolf\")\n        })\n        t.Run(\"nil\", func(t *testing.T) {\n            c := qt.New(t)\n            got := somepackage.MaybeNil()\n            c.Assert(got, qt.IsNil, qt.Commentf(\"value: %v\", somepackage.Value))\n        })\n    }\n\nDeferred execution\n\nQuicktest provides the ability to defer the execution of functions that will be\nrun when the test completes. This is often useful for creating OS-level\nresources such as temporary directories (see c.Mkdir). The functions will be\nrun in last-in, first-out order.\n\n    func (c *C) Defer(f func())\n\nTo trigger the deferred behavior, call c.Done:\n\n    func (c *C) Done()\n\nIf you create a *C instance at the top level, you’ll have to add a defer to\ntrigger the cleanups at the end of the test:\n\n    defer c.Done()\n\nHowever, if you use quicktest to create a subtest, Done will be called\nautomatically at the end of that subtest. For example:\n\n    func TestFoo(t *testing.T) {\n        c := qt.New(t)\n        c.Run(\"subtest\", func(c *qt.C) {\n            c.Setenv(\"HOME\", c.Mkdir())\n            \/\/ Here $HOME is set the path to a newly created directory.\n            \/\/ At the end of the test the directory will be removed\n            \/\/ and HOME set back to its original value.\n        })\n    }\n\nAssertions\n\nAn assertion looks like this, where qt.Equals could be replaced by any\navailable checker. If the assertion fails, the underlying Fatal method is\ncalled to describe the error and abort the test.\n\n    c.Assert(someValue, qt.Equals, wantValue)\n\nIf you don’t want to abort on failure, use Check instead, which calls Error\ninstead of Fatal:\n\n    c.Check(someValue, qt.Equals, wantValue)\n\nThe library provides some base checkers like Equals, DeepEquals, Matches,\nErrorMatches, IsNil and others. More can be added by implementing the Checker\ninterface. Below, we list the checkers implemented by the package in alphabetical\norder.\n\nAll\n\nAll returns a Checker that uses the given checker to check elements of slice or\narray or the values of a map. It succeeds if all elements pass the check.\nOn failure it prints the error from the first index that failed.\n\nFor example:\n\n\tc.Assert([]int{3, 5, 8}, qt.All(qt.Not(qt.Equals)), 0)\n\tc.Assert([][]string{{\"a\", \"b\"}, {\"a\", \"b\"}}, qt.All(qt.DeepEquals), []string{\"c\", \"d\"})\n\nSee also Any and Contains.\n\nAny\n\nAny returns a Checker that uses the given checker to check elements of a slice\nor array or the values from a map. It succeeds if any element passes the check.\n\nFor example:\n\n\tc.Assert([]int{3,5,7,99}, qt.Any(qt.Equals), 7)\n\tc.Assert([][]string{{\"a\", \"b\"}, {\"c\", \"d\"}}, qt.Any(qt.DeepEquals), []string{\"c\", \"d\"})\n\nSee also All and Contains.\n\nCmpEquals\n\nCmpEquals checks equality of two arbitrary values according to the provided\ncompare options. DeepEquals is more commonly used when no compare options are\nrequired.\n\nExample calls:\n\n    c.Assert(list, qt.CmpEquals(cmpopts.SortSlices), []int{42, 47})\n    c.Assert(got, qt.CmpEquals(), []int{42, 47}) \/\/ Same as qt.DeepEquals.\n\nCodecEquals\n\nCodecEquals returns a checker that checks for codec value equivalence.\n\n    func CodecEquals(\n        marshal func(interface{}) ([]byte, error),\n        unmarshal func([]byte, interface{}) error,\n        opts ...cmp.Option,\n    ) Checker\n\nIt expects two arguments: a byte slice or a string containing some\ncodec-marshaled data, and a Go value.\n\nIt uses unmarshal to unmarshal the data into an interface{} value.\nIt marshals the Go value using marshal, then unmarshals the result into\nan interface{} value.\n\nIt then checks that the two interface{} values are deep-equal to one another,\nusing CmpEquals(opts) to perform the check.\n\nSee JSONEquals for an example of this in use.\n\nContains\n\nContains checks that a map, slice, array or string contains a value. It's the\nsame as using Any(Equals), except that it has a special case for strings - if\nthe first argument is a string, the second argument must also be a string and\nstrings.Contains will be used.\n\nFor example:\n\n\tc.Assert(\"hello world\", qt.Contains, \"world\")\n\tc.Assert([]int{3,5,7,99}, qt.Contains, 7)\n\nContentEquals\n\nContentEquals is is like DeepEquals but any slices in the compared values will be sorted before being compared.\n\nFor example:\n\n\tc.Assert([]string{\"c\", \"a\", \"b\"}, qt.ContentEquals, []string{\"a\", \"b\", \"c\"})\n\nDeepEquals\n\nDeepEquals checks that two arbitrary values are deeply equal.\nThe comparison is done using the github.com\/google\/go-cmp\/cmp package.\nWhen comparing structs, by default no exported fields are allowed.\nIf a more sophisticated comparison is required, use CmpEquals (see below).\n\nExample call:\n\n    c.Assert(got, qt.DeepEquals, []int{42, 47})\n\nEquals\n\nEquals checks that two values are equal, as compared with Go's == operator.\n\nFor instance:\n\n    c.Assert(answer, qt.Equals, 42)\n\nNote that the following will fail:\n\n    c.Assert((*sometype)(nil), qt.Equals, nil)\n\nUse the IsNil checker below for this kind of nil check.\n\nErrorMatches\n\nErrorMatches checks that the provided value is an error whose message matches\nthe provided regular expression.\n\nFor instance:\n\n    c.Assert(err, qt.ErrorMatches, `bad wolf .*`)\n\nHasLen\n\nHasLen checks that the provided value has the given length.\n\nFor instance:\n\n    c.Assert([]int{42, 47}, qt.HasLen, 2)\n    c.Assert(myMap, qt.HasLen, 42)\n\nIsNil\n\nIsNil checks that the provided value is nil.\n\nFor instance:\n\n    c.Assert(got, qt.IsNil)\n\nAs a special case, if the value is nil but implements the\nerror interface, it is still considered to be non-nil.\nThis means that IsNil will fail on an error value that happens\nto have an underlying nil value, because that's\ninvariably a mistake. See https:\/\/golang.org\/doc\/faq#nil_error.\n\nSo it's just fine to check an error like this:\n\n    c.Assert(err, qt.IsNil)\n\nJSONEquals\n\nJSONEquals checks whether a byte slice or string is JSON-equivalent to a Go\nvalue. See CodecEquals for more information.\n\nIt uses DeepEquals to do the comparison. If a more sophisticated comparison is\nrequired, use CodecEquals directly.\n\nFor instance:\n\n    c.Assert(`{\"First\": 47.11}`, qt.JSONEquals, &MyStruct{First: 47.11})\n\nMatches\n\nMatches checks that a string or result of calling the String method\n(if the value implements fmt.Stringer) matches the provided regular expression.\n\nFor instance:\n\n    c.Assert(\"these are the voyages\", qt.Matches, `these are .*`)\n    c.Assert(net.ParseIP(\"1.2.3.4\"), qt.Matches, `1.*`)\n\nNot\n\nNot returns a Checker negating the given Checker.\n\nFor instance:\n\n    c.Assert(got, qt.Not(qt.IsNil))\n    c.Assert(answer, qt.Not(qt.Equals), 42)\n\nPanicMatches\n\nPanicMatches checks that the provided function panics with a message matching\nthe provided regular expression.\n\nFor instance:\n\n    c.Assert(func() {panic(\"bad wolf ...\")}, qt.PanicMatches, `bad wolf .*`)\n\nSatisfies\n\nSatisfies checks that the provided value, when used as argument of the provided\npredicate function, causes the function to return true. The function must be of\ntype func(T) bool, having got assignable to T.\n\nFor instance:\n\n    \/\/ Check that an error from os.Open satisfies os.IsNotExist.\n    c.Assert(err, qt.Satisfies, os.IsNotExist)\n\n    \/\/ Check that a floating point number is a not-a-number.\n    c.Assert(f, qt.Satisfies, math.IsNaN)\n*\/\npackage quicktest\n<commit_msg>Add IsTrue and IsFalse to doc.go<commit_after>\/\/ Licensed under the MIT license, see LICENCE file for details.\n\n\/*\nPackage quicktest provides a collection of Go helpers for writing tests.\n\nQuicktest helpers can be easily integrated inside regular Go tests, for\ninstance:\n\n    import qt \"github.com\/frankban\/quicktest\"\n\n    func TestFoo(t *testing.T) {\n        t.Run(\"numbers\", func(t *testing.T) {\n            c := qt.New(t)\n            numbers, err := somepackage.Numbers()\n            c.Assert(numbers, qt.DeepEquals, []int{42, 47})\n            c.Assert(err, qt.ErrorMatches, \"bad wolf\")\n        })\n        t.Run(\"nil\", func(t *testing.T) {\n            c := qt.New(t)\n            got := somepackage.MaybeNil()\n            c.Assert(got, qt.IsNil, qt.Commentf(\"value: %v\", somepackage.Value))\n        })\n    }\n\nDeferred execution\n\nQuicktest provides the ability to defer the execution of functions that will be\nrun when the test completes. This is often useful for creating OS-level\nresources such as temporary directories (see c.Mkdir). The functions will be\nrun in last-in, first-out order.\n\n    func (c *C) Defer(f func())\n\nTo trigger the deferred behavior, call c.Done:\n\n    func (c *C) Done()\n\nIf you create a *C instance at the top level, you’ll have to add a defer to\ntrigger the cleanups at the end of the test:\n\n    defer c.Done()\n\nHowever, if you use quicktest to create a subtest, Done will be called\nautomatically at the end of that subtest. For example:\n\n    func TestFoo(t *testing.T) {\n        c := qt.New(t)\n        c.Run(\"subtest\", func(c *qt.C) {\n            c.Setenv(\"HOME\", c.Mkdir())\n            \/\/ Here $HOME is set the path to a newly created directory.\n            \/\/ At the end of the test the directory will be removed\n            \/\/ and HOME set back to its original value.\n        })\n    }\n\nAssertions\n\nAn assertion looks like this, where qt.Equals could be replaced by any\navailable checker. If the assertion fails, the underlying Fatal method is\ncalled to describe the error and abort the test.\n\n    c.Assert(someValue, qt.Equals, wantValue)\n\nIf you don’t want to abort on failure, use Check instead, which calls Error\ninstead of Fatal:\n\n    c.Check(someValue, qt.Equals, wantValue)\n\nThe library provides some base checkers like Equals, DeepEquals, Matches,\nErrorMatches, IsNil and others. More can be added by implementing the Checker\ninterface. Below, we list the checkers implemented by the package in alphabetical\norder.\n\nAll\n\nAll returns a Checker that uses the given checker to check elements of slice or\narray or the values of a map. It succeeds if all elements pass the check.\nOn failure it prints the error from the first index that failed.\n\nFor example:\n\n\tc.Assert([]int{3, 5, 8}, qt.All(qt.Not(qt.Equals)), 0)\n\tc.Assert([][]string{{\"a\", \"b\"}, {\"a\", \"b\"}}, qt.All(qt.DeepEquals), []string{\"c\", \"d\"})\n\nSee also Any and Contains.\n\nAny\n\nAny returns a Checker that uses the given checker to check elements of a slice\nor array or the values from a map. It succeeds if any element passes the check.\n\nFor example:\n\n\tc.Assert([]int{3,5,7,99}, qt.Any(qt.Equals), 7)\n\tc.Assert([][]string{{\"a\", \"b\"}, {\"c\", \"d\"}}, qt.Any(qt.DeepEquals), []string{\"c\", \"d\"})\n\nSee also All and Contains.\n\nCmpEquals\n\nCmpEquals checks equality of two arbitrary values according to the provided\ncompare options. DeepEquals is more commonly used when no compare options are\nrequired.\n\nExample calls:\n\n    c.Assert(list, qt.CmpEquals(cmpopts.SortSlices), []int{42, 47})\n    c.Assert(got, qt.CmpEquals(), []int{42, 47}) \/\/ Same as qt.DeepEquals.\n\nCodecEquals\n\nCodecEquals returns a checker that checks for codec value equivalence.\n\n    func CodecEquals(\n        marshal func(interface{}) ([]byte, error),\n        unmarshal func([]byte, interface{}) error,\n        opts ...cmp.Option,\n    ) Checker\n\nIt expects two arguments: a byte slice or a string containing some\ncodec-marshaled data, and a Go value.\n\nIt uses unmarshal to unmarshal the data into an interface{} value.\nIt marshals the Go value using marshal, then unmarshals the result into\nan interface{} value.\n\nIt then checks that the two interface{} values are deep-equal to one another,\nusing CmpEquals(opts) to perform the check.\n\nSee JSONEquals for an example of this in use.\n\nContains\n\nContains checks that a map, slice, array or string contains a value. It's the\nsame as using Any(Equals), except that it has a special case for strings - if\nthe first argument is a string, the second argument must also be a string and\nstrings.Contains will be used.\n\nFor example:\n\n\tc.Assert(\"hello world\", qt.Contains, \"world\")\n\tc.Assert([]int{3,5,7,99}, qt.Contains, 7)\n\nContentEquals\n\nContentEquals is is like DeepEquals but any slices in the compared values will be sorted before being compared.\n\nFor example:\n\n\tc.Assert([]string{\"c\", \"a\", \"b\"}, qt.ContentEquals, []string{\"a\", \"b\", \"c\"})\n\nDeepEquals\n\nDeepEquals checks that two arbitrary values are deeply equal.\nThe comparison is done using the github.com\/google\/go-cmp\/cmp package.\nWhen comparing structs, by default no exported fields are allowed.\nIf a more sophisticated comparison is required, use CmpEquals (see below).\n\nExample call:\n\n    c.Assert(got, qt.DeepEquals, []int{42, 47})\n\nEquals\n\nEquals checks that two values are equal, as compared with Go's == operator.\n\nFor instance:\n\n    c.Assert(answer, qt.Equals, 42)\n\nNote that the following will fail:\n\n    c.Assert((*sometype)(nil), qt.Equals, nil)\n\nUse the IsNil checker below for this kind of nil check.\n\nErrorMatches\n\nErrorMatches checks that the provided value is an error whose message matches\nthe provided regular expression.\n\nFor instance:\n\n    c.Assert(err, qt.ErrorMatches, `bad wolf .*`)\n\nHasLen\n\nHasLen checks that the provided value has the given length.\n\nFor instance:\n\n    c.Assert([]int{42, 47}, qt.HasLen, 2)\n    c.Assert(myMap, qt.HasLen, 42)\n\nIsFalse\n\nIsFalse checks that the provided value is false.\nThe value must have a boolean underlying type.\n\nFor instance:\n\n    c.Assert(false, qt.IsFalse)\n    c.Assert(IsValid(), qt.IsFalse)\n\nIsNil\n\nIsNil checks that the provided value is nil.\n\nFor instance:\n\n    c.Assert(got, qt.IsNil)\n\nAs a special case, if the value is nil but implements the\nerror interface, it is still considered to be non-nil.\nThis means that IsNil will fail on an error value that happens\nto have an underlying nil value, because that's\ninvariably a mistake. See https:\/\/golang.org\/doc\/faq#nil_error.\n\nSo it's just fine to check an error like this:\n\n    c.Assert(err, qt.IsNil)\n\nIsTrue\n\nIsTrue checks that the provided value is true.\nThe value must have a boolean underlying type.\n\nFor instance:\n\n    c.Assert(true, qt.IsTrue)\n    c.Assert(myBoolean(false), qt.IsTrue)\n\nJSONEquals\n\nJSONEquals checks whether a byte slice or string is JSON-equivalent to a Go\nvalue. See CodecEquals for more information.\n\nIt uses DeepEquals to do the comparison. If a more sophisticated comparison is\nrequired, use CodecEquals directly.\n\nFor instance:\n\n    c.Assert(`{\"First\": 47.11}`, qt.JSONEquals, &MyStruct{First: 47.11})\n\nMatches\n\nMatches checks that a string or result of calling the String method\n(if the value implements fmt.Stringer) matches the provided regular expression.\n\nFor instance:\n\n    c.Assert(\"these are the voyages\", qt.Matches, `these are .*`)\n    c.Assert(net.ParseIP(\"1.2.3.4\"), qt.Matches, `1.*`)\n\nNot\n\nNot returns a Checker negating the given Checker.\n\nFor instance:\n\n    c.Assert(got, qt.Not(qt.IsNil))\n    c.Assert(answer, qt.Not(qt.Equals), 42)\n\nPanicMatches\n\nPanicMatches checks that the provided function panics with a message matching\nthe provided regular expression.\n\nFor instance:\n\n    c.Assert(func() {panic(\"bad wolf ...\")}, qt.PanicMatches, `bad wolf .*`)\n\nSatisfies\n\nSatisfies checks that the provided value, when used as argument of the provided\npredicate function, causes the function to return true.

The first is package pgtype provides types that have a data field and a status field.\nThey work in a similar fashion to database\/sql. The second is to use a pointer to a pointer.\n\n    var foo pgtype.Varchar\n    var bar *string\n    err := conn.QueryRow(\"select foo, bar from widgets where id=$1\", 42).Scan(&foo, &bar)\n    if err != nil {\n        return err\n    }\n\nArray Mapping\n\npgx maps between int16, int32, int64, float32, float64, and string Go slices and the equivalent PostgreSQL array type.\nGo slices of native types do not support nulls, so if a PostgreSQL array that contains a null is read into a native Go\nslice an error will occur. The pgtype package includes many more array types for PostgreSQL types that do not directly\nmap to native Go types.\n\nJSON and JSONB Mapping\n\npgx includes built-in support to marshal and unmarshal between Go types and the PostgreSQL JSON and JSONB.\n\nInet and CIDR Mapping\n\npgx encodes from net.IPNet to and from inet and cidr PostgreSQL types. In addition, as a convenience pgx will encode\nfrom a net.IP; it will assume a \/32 netmask for IPv4 and a \/128 for IPv6.\n\nCustom Type Support\n\npgx includes support for the common data types like integers, floats, strings, dates, and times that have direct\nmappings between Go and SQL. In addition, pgx uses the github.com\/jackc\/pgx\/pgtype library to support more types. See\ndocumention for that library for instructions on how to implement custom types.\n\nSee example_custom_type_test.go for an example of a custom type for the PostgreSQL point type.\n\npgx also includes support for custom types implementing the database\/sql.Scanner and database\/sql\/driver.Valuer\ninterfaces.\n\nIf pgx does cannot natively encode a type and that type is a renamed type (e.g. type MyTime time.Time) pgx will attempt\nto encode the underlying type. While this is usually desired behavior it can produce surprising behavior if one the\nunderlying type and the renamed type each implement database\/sql interfaces and the other implements pgx interfaces. It\nis recommended that this situation be avoided by implementing pgx interfaces on the renamed type.\n\nComposite types and row values\n\nRow values and composite types are represented as pgtype.Record (https:\/\/pkg.go.dev\/github.com\/jackc\/pgtype?tab=doc#Record).\nIt is possible to get values of your custom type by implementing DecodeBinary interface. Decoding into\npgtype.Record first can simplify process by avoiding dealing with raw protocol directly.\n\nFor example:\n\n    type MyType struct {\n        a int      \/\/ NULL will cause decoding error\n        b *string  \/\/ there can be NULL in this position in SQL\n    }\n\n    func (t *MyType) DecodeBinary(ci *pgtype.ConnInfo, src []byte) error {\n        r := pgtype.Record{\n            Fields: []pgtype.Value{&pgtype.Int4{}, &pgtype.Text{}},\n        }\n\n        if err := r.DecodeBinary(ci, src); err != nil {\n            return err\n        }\n\n        if r.Status != pgtype.Present {\n            return errors.New(\"BUG: decoding should not be called on NULL value\")\n        }\n\n        a := r.Fields[0].(*pgtype.Int4)\n        b := r.Fields[1].(*pgtype.Text)\n\n        \/\/ type compatibility is checked by AssignTo\n        \/\/ only lossless assignments will succeed\n        if err := a.AssignTo(&t.a); err != nil {\n            return err\n        }\n\n        \/\/ AssignTo also deals with null value handling\n        if err := b.AssignTo(&t.b); err != nil {\n            return err\n        }\n        return nil\n    }\n\n    result := MyType{}\n    err := conn.QueryRow(context.Background(), \"select row(1, 'foo'::text)\", pgx.QueryResultFormats{pgx.BinaryFormatCode}).Scan(&r)\n\nRaw Bytes Mapping\n\n[]byte passed as arguments to Query, QueryRow, and Exec are passed unmodified to PostgreSQL.\n\nTransactions\n\nTransactions are started by calling Begin.\n\n    tx, err := conn.Begin(context.Background())\n    if err != nil {\n        return err\n    }\n    \/\/ Rollback is safe to call even if the tx is already closed, so if\n    \/\/ the tx commits successfully, this is a no-op\n    defer tx.Rollback(context.Background())\n\n    _, err = tx.Exec(context.Background(), \"insert into foo(id) values (1)\")\n    if err != nil {\n        return err\n    }\n\n    err = tx.Commit(context.Background())\n    if err != nil {\n        return err\n    }\n\nThe Tx returned from Begin also implements the Begin method. This can be used to implement pseudo nested transactions.\nThese are internally implemented with savepoints.\n\nUse BeginTx to control the transaction mode.\n\nPrepared Statements\n\nPrepared statements can be manually created with the Prepare method. However, this is rarely necessary because pgx\nincludes an automatic statement cache by default. Queries run through the normal Query, QueryRow, and Exec functions are\nautomatically prepared on first execution and the prepared statement is reused on subsequent executions. See ParseConfig\nfor information on how to customize or disable the statement cache.\n\nCopy Protocol\n\nUse CopyFrom to efficiently insert multiple rows at a time using the PostgreSQL copy protocol. CopyFrom accepts a\nCopyFromSource interface. If the data is already in a [][]interface{} use CopyFromRows to wrap it in a CopyFromSource\ninterface. Or implement CopyFromSource to avoid buffering the entire data set in memory.\n\n    rows := [][]interface{}{\n        {\"John\", \"Smith\", int32(36)},\n        {\"Jane\", \"Doe\", int32(29)},\n    }\n\n    copyCount, err := conn.CopyFrom(\n        context.Background(),\n        pgx.Identifier{\"people\"},\n        []string{\"first_name\", \"last_name\", \"age\"},\n        pgx.CopyFromRows(rows),\n    )\n\nCopyFrom can be faster than an insert with as few as 5 rows.\n\nListen and Notify\n\npgx can listen to the PostgreSQL notification system with the `Conn.WaitForNotification` method. It blocks until a\ncontext is received or the context is canceled.\n\n    _, err := conn.Exec(context.Background(), \"listen channelname\")\n    if err != nil {\n        return nil\n    }\n\n    if notification, err := conn.WaitForNotification(context.Background()); err != nil {\n        \/\/ do something with notification\n    }\n\n\nLogging\n\npgx defines a simple logger interface. Connections optionally accept a logger that satisfies this interface. Set\nLogLevel to control logging verbosity. Adapters for github.com\/inconshreveable\/log15, github.com\/sirupsen\/logrus,\ngo.uber.org\/zap, github.com\/rs\/zerolog, and the testing log are provided in the log directory.\n\nLower Level PostgreSQL Functionality\n\npgx is implemented on top of github.com\/jackc\/pgconn a lower level PostgreSQL driver. The Conn.PgConn() method can be\nused to access this lower layer.\n\nPgBouncer\n\npgx is compatible with PgBouncer in two modes. One is when the connection has a statement cache in \"describe\" mode. The\nother is when the connection is using the simple protocol. This can be set with the PreferSimpleProtocol config option.\n*\/\npackage pgx\n<commit_msg>Tweak docs to make conn \/ conn pool distinction clearer<commit_after>\/\/ Package pgx is a PostgreSQL database driver.\n\/*\npgx provides lower level access to PostgreSQL than the standard database\/sql. It remains as similar to the database\/sql\ninterface as possible while providing better speed and access to PostgreSQL specific features. Import\ngithub.com\/jackc\/pgx\/v4\/stdlib to use pgx as a database\/sql compatible driver.\n\nEstablishing a Connection\n\nThe primary way of establishing a connection is with `pgx.Connect`.\n\n    conn, err := pgx.Connect(context.Background(), os.Getenv(\"DATABASE_URL\"))\n\nThe database connection string can be in URL or DSN format. Both PostgreSQL settings and pgx settings can be specified\nhere. In addition, a config struct can be created by `ParseConfig` and modified before establishing the connection with\n`ConnectConfig`.\n\n    config, err := pgx.ParseConfig(os.Getenv(\"DATABASE_URL\"))\n    if err != nil {\n        \/\/ ...\n    }\n    config.Logger = log15adapter.NewLogger(log.New(\"module\", \"pgx\"))\n\n    conn, err := pgx.ConnectConfig(context.Background(), config)\n\nConnection Pool\n\n`*pgx.Conn` represents a single connection to the database and is not concurrency safe. Use sub-package pgxpool for a\nconcurrency safe connection pool.\n\nQuery Interface\n\npgx implements Query and Scan in the familiar database\/sql style.\n\n    var sum int32\n\n    \/\/ Send the query to the server. The returned rows MUST be closed\n    \/\/ before conn can be used again.\n    rows, err := conn.Query(context.Background(), \"select generate_series(1,$1)\", 10)\n    if err != nil {\n        return err\n    }\n\n    \/\/ rows.Close is called by rows.Next when all rows are read\n    \/\/ or an error occurs in Next or Scan. So it may optionally be\n    \/\/ omitted if nothing in the rows.Next loop can panic. It is\n    \/\/ safe to close rows multiple times.\n    defer rows.Close()\n\n    \/\/ Iterate through the result set\n    for rows.Next() {\n        var n int32\n        err = rows.Scan(&n)\n        if err != nil {\n            return err\n        }\n        sum += n\n    }\n\n    \/\/ Any errors encountered by rows.Next or rows.Scan will be returned here\n    if rows.Err() != nil {\n        return rows.Err()\n    }\n\n    \/\/ No errors found - do something with sum\n\npgx also implements QueryRow in the same style as database\/sql.\n\n    var name string\n    var weight int64\n    err := conn.QueryRow(context.Background(), \"select name, weight from widgets where id=$1\", 42).Scan(&name, &weight)\n    if err != nil {\n        return err\n    }\n\nUse Exec to execute a query that does not return a result set.\n\n    commandTag, err := conn.Exec(context.Background(), \"delete from widgets where id=$1\", 42)\n    if err != nil {\n        return err\n    }\n    if commandTag.RowsAffected() != 1 {\n        return errors.New(\"No row found to delete\")\n    }\n\nBase Type Mapping\n\npgx maps between all common base types directly between Go and PostgreSQL. In particular:\n\n    Go           PostgreSQL\n    -----------------------\n    string       varchar\n                 text\n\n    \/\/ Integers are automatically be converted to any other integer type if\n    \/\/ it can be done without overflow or underflow.\n    int8\n    int16        smallint\n    int32        int\n    int64        bigint\n    int\n    uint8\n    uint16\n    uint32\n    uint64\n    uint\n\n    \/\/ Floats are strict and do not automatically convert like integers.\n    float32      float4\n    float64      float8\n\n    time.Time   date\n                timestamp\n                timestamptz\n\n    []byte      bytea\n\n\nNull Mapping\n\npgx can map nulls in two ways. The first is package pgtype provides types that have a data field and a status field.\nThey work in a similar fashion to database\/sql. The second is to use a pointer to a pointer.\n\n    var foo pgtype.Varchar\n    var bar *string\n    err := conn.QueryRow(\"select foo, bar from widgets where id=$1\", 42).Scan(&foo, &bar)\n    if err != nil {\n        return err\n    }\n\nArray Mapping\n\npgx maps between int16, int32, int64, float32, float64, and string Go slices and the equivalent PostgreSQL array type.\nGo slices of native types do not support nulls, so if a PostgreSQL array that contains a null is read into a native Go\nslice an error will occur. The pgtype package includes many more array types for PostgreSQL types that do not directly\nmap to native Go types.\n\nJSON and JSONB Mapping\n\npgx includes built-in support to marshal and unmarshal between Go types and the PostgreSQL JSON and JSONB.\n\nInet and CIDR Mapping\n\npgx encodes from net.IPNet to and from inet and cidr PostgreSQL types. In addition, as a convenience pgx will encode\nfrom a net.IP; it will assume a \/32 netmask for IPv4 and a \/128 for IPv6.\n\nCustom Type Support\n\npgx includes support for the common data types like integers, floats, strings, dates, and times that have direct\nmappings between Go and SQL. In addition, pgx uses the github.com\/jackc\/pgx\/pgtype library to support more types. See\ndocumention for that library for instructions on how to implement custom types.\n\nSee example_custom_type_test.go for an example of a custom type for the PostgreSQL point type.\n\npgx also includes support for custom types implementing the database\/sql.Scanner and database\/sql\/driver.Valuer\ninterfaces.\n\nIf pgx does cannot natively encode a type and that type is a renamed type (e.g. type MyTime time.Time) pgx will attempt\nto encode the underlying type. While this is usually desired behavior it can produce surprising behavior if one the\nunderlying type and the renamed type each implement database\/sql interfaces and the other implements pgx interfaces.

{"text":"<commit_before>\/*\nCommand pigeon generates parsers in Go from a PEG grammar.\n\nFrom Wikipedia [0]:\n\n\tA parsing expression grammar is a type of analytic formal grammar, i.e.\n\tit describes a formal language in terms of a set of rules for recognizing\n\tstrings in the language.\n\nIts features and syntax are inspired by the PEG.js project [1], while\nthe implementation is loosely based on [2]. Formal presentation of the\nPEG theory by Bryan Ford is also an important reference [3].\n\n\t[0]: http:\/\/en.wikipedia.org\/wiki\/Parsing_expression_grammar\n\t[1]: http:\/\/pegjs.org\/\n\t[2]: http:\/\/www.codeproject.com\/Articles\/29713\/Parsing-Expression-Grammar-Support-for-C-Part\n\t[3]: http:\/\/pdos.csail.mit.edu\/~baford\/packrat\/popl04\/peg-popl04.pdf\n\nCommand-line usage\n\nThe pigeon tool must be called with a PEG grammar file as defined\nby the accepted PEG syntax below. The grammar may be provided by a\nfile or read from stdin. The generated parser is written to stdout\nby default.\n\n\tpigeon [options] [GRAMMAR_FILE]\n\nThe following options can be specified:\n\n\t-cache : cache parser results to avoid exponential parsing time in\n\tpathological cases. Can make the parsing slower for typical\n\tcases and uses more memory (default: false).\n\n\t-debug : boolean, print debugging info to stdout (default: false).\n\n\t-o=FILE : string, output file where the generated parser will be\n\twritten (default: stdout).\n\n\t-x : boolean, if set, do not build the parser, just parse the input grammar\n\t(default: false).\n\n\t-receiver-name=NAME : string, name of the receiver variable for the generated\n\tcode blocks. Non-initializer code blocks in the grammar end up as methods on the\n\t*current type, and this option sets the name of the receiver (default: c).\n\nThe tool makes no attempt to format the code, nor to detect the\nrequired imports. It is recommended to use goimports to properly generate\nthe output code:\n\tpigeon GRAMMAR_FILE | goimports > output_file.go\n\nThe goimports tool can be installed with:\n\tgo get golang.org\/x\/tools\/cmd\/goimports\n\nIf the code blocks in the grammar are golint- and go vet-compliant, then\nthe resulting generated code will also be golint- and go vet-compliant.\n\nThe generated code doesn't use any third-party dependency unless code blocks\nin the grammar require such a dependency.\n\nPEG syntax\n\nThe accepted syntax for the grammar is formally defined in the\ngrammar\/pigeon.peg file, using the PEG syntax. What follows is an informal\ndescription of this syntax.\n\nIdentifiers, whitespace, comments and literals follow the same\nnotation as the Go language, as defined in the language specification\n(http:\/\/golang.org\/ref\/spec#Source_code_representation):\n\n\t\/\/ single line comment*\/\n\/\/\t\/* multi-line comment *\/\n\/*\t'x' (single quotes for single char literal)\n\t\"double quotes for string literal\"\n\t`backtick quotes for raw string literal`\n\tRuleName (a valid identifier)\n\nThe grammar must be Unicode text encoded in UTF-8. New lines are identified\nby the \\n character (U+000A). Space (U+0020), horizontal tabs (U+0009) and\ncarriage returns (U+000D) are considered whitespace and are ignored except\nto separate tokens.\n\nRules\n\nA PEG grammar consists of a set of rules. A rule is an identifier followed\nby a rule definition operator and an expression. An optional display name -\na string literal used in error messages instead of the rule identifier - can\nbe specified after the rule identifier. E.g.:\n\tRuleA \"friendly name\" = 'a'+ \/\/ RuleA is one or more lowercase 'a's\n\nThe rule definition operator can be any one of those:\n\t=, <-, ← (U+2190), ⟵ (U+27F5)\n\nExpressions\n\nA rule is defined by an expression. The following sections describe the\nvarious expression types. Expressions can be grouped by using parentheses,\nand a rule can be referenced by its identifier in place of an expression.\n\nChoice expression\n\nThe choice expression is a list of expressions that will be tested in the\norder they are defined. The first one that matches will be used. Expressions\nare separated by the forward slash character \"\/\". E.g.:\n\tChoiceExpr = A \/ B \/ C \/\/ A, B and C should be rules declared in the grammar\n\nBecause the first match is used, it is important to think about the order\nof expressions. For example, in this rule, \"<=\" would never be used because\nthe \"<\" expression comes first:\n\tBadChoiceExpr = \"<\" \/ \"<=\"\n\nSequence expression\n\nThe sequence expression is a list of expressions that must all match in\nthat same order for the sequence expression to be considered a match.\nExpressions are separated by whitespace. E.g.:\n\tSeqExpr = \"A\" \"b\" \"c\" \/\/ matches \"Abc\", but not \"Acb\"\n\nLabeled expression\n\nA labeled expression consists of an identifier followed by a colon \":\"\nand an expression. A labeled expression introduces a variable named with\nthe label that can be referenced in the expression's code block.\nThe variable will have the value of the expression that follows the colon.\nE.g.:\n\tLabeledExpr = value:[a-z]+ {\n\t\tfmt.Println(value)\n\t\treturn value, nil\n\t}\n\nAnd and not expressions\n\nAn expression prefixed with the ampersand \"&\" is the \"and\" predicate\nexpression: it is considered a match if the following expression is a match,\nbut it does not consume any input.\n\nAn expression prefixed with the exclamation point \"!\" is the \"not\" predicate\nexpression: it is considered a match if the following expression is not\na match, but it does not consume any input. E.g.:\n\tAndExpr = \"A\" &\"B\" \/\/ matches \"A\" if followed by a \"B\" (does not consume \"B\")\n\tNotExpr = \"A\" !\"B\" \/\/ matches \"A\" if not followed by a \"B\" (does not consume \"B\")\n\nThe expression following the & and ! operators can be a code block. In that\ncase, the code block must return a bool and an error. The operator's semantic\nis the same, & is a match if the code block returns true, ! is a match if the\ncode block returns false. The code block has access to any labeled value\ndefined in its scope. E.g.:\n\tCodeAndExpr = value:[a-z] &{\n\t\t\/\/ can access the value local variable...\n\t\treturn true, nil\n\t}\n\nRepeating expressions\n\nAn expression followed by \"*\", \"?\" or \"+\" is a match if the expression\noccurs zero or more times (\"*\"), zero or one time \"?\" or one or more times\n(\"+\") respectively. The match is greedy, it will match as many times as\npossible. E.g.\n\tZeroOrMoreAs = \"A\"*\n\nLiteral matcher\n\nA literal matcher tries to match the input against a single character or a\nstring literal. The literal may be a single-quoted single character, a\ndouble-quoted string or a backtick-quoted raw string. The same rules as in Go\napply regarding the allowed characters and escapes.\n\nThe literal may be followed by a lowercase \"i\" (outside the ending quote)\nto indicate that the match is case-insensitive. E.g.:\n\tLiteralMatch = \"Awesome\\n\"i \/\/ matches \"awesome\" followed by a newline\n\nCharacter class matcher\n\nA character class matcher tries to match the input against a class of characters\ninside square brackets \"[...]\". Inside the brackets, characters represent\nthemselves and the same escapes as in string literals are available, except\nthat the single- and double-quote escape is not valid, instead the closing\nsquare bracket \"]\" must be escaped to be used.\n\nCharacter ranges can be specified using the \"[a-z]\" notation. Unicode\nclasses can be specified using the \"[\\pL]\" notation, where L is a\nsingle-letter Unicode class of characters, or using the \"[\\p{Class}]\"\nnotation where Class is a valid Unicode class (e.g. \"Latin\").\n\nAs for string literals, a lowercase \"i\" may follow the matcher (outside\nthe ending square bracket) to indicate that the match is case-insensitive.\nA \"^\" as first character inside the square brackets indicates that the match\nis inverted (it is a match if the input does not match the character class\nmatcher). E.g.:\n\tNotAZ = [^a-z]i\n\nAny matcher\n\nThe any matcher is represented by the dot \".\". It matches any character\nexcept the end of file, thus the \"!.\" expression is used to indicate \"match\nthe end of file\". E.g.:\n\tAnyChar = . \/\/ match a single character\n\tEOF = !.\n\nCode block\n\nCode blocks can be added to generate custom Go code. There are three kinds\nof code blocks: the initializer, the action and the predicate. All code blocks\nappear inside curly braces \"{...}\".\n\nThe initializer must appear first in the grammar, before any rule. It is\ncopied as-is (minus the wrapping curly braces) at the top of the generated\nparser. It may contain function declarations, types, variables, etc. just\nlike any Go file. Every symbol declared here will be available to all other\ncode blocks.  Although the initializer is optional in a valid grammar, it is\nusually required to generate a valid Go source code file (for the package\nclause). E.g.:\n\t{\n\t\tpackage main\n\n\t\tfunc someHelper() {\n\t\t\t\/\/ ...\n\t\t}\n\t}\n\nAction code blocks are code blocks declared after an expression in a rule.\nThose code blocks are turned into a method on the \"*current\" type in the\ngenerated source code. The method receives any labeled expression's value\nas argument (as interface{}) and must return two values, the first being\nthe value of the expression (an interface{}), and the second an error.\nIf a non-nil error is returned, it is added to the list of errors that the\nparser will return. E.g.:\n\tRuleA = \"A\"+ {\n\t\t\/\/ return the matched string, \"c\" is the default name for\n\t\t\/\/ the *current receiver variable.\n\t\treturn string(c.text), nil\n\t}\n\nPredicate code blocks are code blocks declared immediately after the and \"&\"\nor the not \"!\" operators. Like action code blocks, predicate code blocks\nare turned into a method on the \"*current\" type in the generated source code.\nThe method receives any labeled expression's value as argument (as interface{})\nand must return two values, the first being a bool and the second an error.\nIf a non-nil error is returned, it is added to the list of errors that the\nparser will return. E.g.:\n\tRuleAB = [ab]i+ &{\n\t\treturn true, nil\n\t}\n\nThe current type is a struct that provides two useful fields that can be\naccessed in action and predicate code blocks: \"pos\" and \"text\".\n\nThe \"pos\" field indicates the current position of the parser in the source\ninput. It is itself a struct with three fields: \"line\", \"col\" and \"offset\".\nLine is a 1-based line number, col is a 1-based column number that counts\nrunes from the start of the line, and offset is a 0-based byte offset.\n\nThe \"text\" field is the slice of bytes of the current match. It is empty\nin a predicate code block.\n\nUsing the generated parser\n\nThe parser generated by pigeon exports a few symbols so that it can be used\nas a package with public functions to parse input text. The exported API is:\n\t- Parse(string, []byte) (interface{}, error)\n\t- ParseFile(string) (interface{}, error)\n\t- ParseReader(string, io.Reader) (interface{}, error)\n\nSee the godoc page of the generated parser for the test\/predicates grammar\nfor an example documentation page of the exported API:\nhttp:\/\/godoc.org\/github.com\/PuerkitoBio\/pigeon\/test\/predicates.\n\nLike the grammar used to generate the parser, the input text must be\nUTF-8-encoded Unicode.\n\nThe start rule of the parser is the first rule in the PEG grammar used\nto generate the parser. A call to any of the Parse* functions returns\nthe value generated by executing the grammar on the provided input text,\nand an optional error.\n\nTypically, the grammar should generate some kind of abstract syntax tree (AST),\nbut for simple grammars it may evaluate the result immediately, such as in\nthe examples\/calculator example. There are no constraints imposed on the\nauthor of the grammar, it can return whatever is needed.\n\nError reporting\n\nWhen the parser returns a non-nil error, the error is always of type errList,\nwhich is defined as a slice of errors ([]error). Each error in the list is\nof type *parserError. This is a struct that has an \"Inner\" field that can be\nused to access the original error.\n\nSo if a code block returns some well-known error like:\n\t{\n\t\treturn nil, io.EOF\n\t}\n\nThe original error can be accessed this way:\n\t_, err := ParseFile(\"some_file\")\n\tif err != nil {\n\t\tlist := err.(errList)\n\t\tfor _, err := range list {\n\t\t\tpe := err.(*parserError)\n\t\t\tif pe.Inner == io.EOF {\n\t\t\t\t\/\/ ...\n\t\t\t}\n\t\t}\n\t}\n\nBy defaut the parser will continue after an error is returned and will\ncumulate all errors found during parsing. If the grammar reaches a point\nwhere it shouldn't continue, a panic statement can be used to terminate\nparsing. The panic will be caught at the top-level of the Parse* call\nand will be converted into a *parserError like any error, and an errList\nwill still be returned to the caller.\n\nThe divide by zero error in the examples\/calculator grammar leverages this\nfeature (no special code is needed to handle division by zero, if it\nhappens, the runtime panics and it is recovered and returned as a parsing\nerror).\n\nProviding good error reporting in a parser is not a trivial task. Part\nof it is provided by the pigeon tool, by offering features such as\nfilename, position and rule name in the error message, but an\nimportant part of good error reporting needs to be done by the grammar\nauthor.\n\nFor example, many programming languages use double-quotes for string literals.\nUsually, if the opening quote is found, the closing quote is expected, and if\nnone is found, there won't be any other rule that will match, there's no need\nto backtrack and try other choices, an error should be added to the list\nand the match should be consumed.\n\nIn order to do this, the grammar can look something like this:\n\n\tStringLiteral = '\"' ValidStringChar* '\"' {\n\t\t\/\/ this is the valid case, build string literal node\n\t\t\/\/ node = ...\n\t\treturn node, nil\n\t} \/ '\"'  ValidStringChar* !'\"' {\n\t\t\/\/ invalid case, build a replacement string literal node or build a BadNode\n\t\t\/\/ node = ...\n\t\treturn node, errors.New(\"string literal not terminated\")\n\t}\n\nThis is just one example, but it illustrates the idea that error reporting\nneeds to be thought out when designing the grammar.\n\n*\/\npackage main\n<commit_msg>doc: document new Option API<commit_after>\/*\nCommand pigeon generates parsers in Go from a PEG grammar.\n\nFrom Wikipedia [0]:\n\n\tA parsing expression grammar is a type of analytic formal grammar, i.e.\n\tit describes a formal language in terms of a set of rules for recognizing\n\tstrings in the language.\n\nIts features and syntax are inspired by the PEG.js project [1], while\nthe implementation is loosely based on [2]. Formal presentation of the\nPEG theory by Bryan Ford is also an important reference [3].\n\n\t[0]: http:\/\/en.wikipedia.org\/wiki\/Parsing_expression_grammar\n\t[1]: http:\/\/pegjs.org\/\n\t[2]: http:\/\/www.codeproject.com\/Articles\/29713\/Parsing-Expression-Grammar-Support-for-C-Part\n\t[3]: http:\/\/pdos.csail.mit.edu\/~baford\/packrat\/popl04\/peg-popl04.pdf\n\nCommand-line usage\n\nThe pigeon tool must be called with a PEG grammar file as defined\nby the accepted PEG syntax below. The grammar may be provided by a\nfile or read from stdin. The generated parser is written to stdout\nby default.\n\n\tpigeon [options] [GRAMMAR_FILE]\n\nThe following options can be specified:\n\n\t-cache : cache parser results to avoid exponential parsing time in\n\tpathological cases. Can make the parsing slower for typical\n\tcases and uses more memory (default: false).\n\n\t-debug : boolean, print debugging info to stdout (default: false).\n\n\t-o=FILE : string, output file where the generated parser will be\n\twritten (default: stdout).\n\n\t-x : boolean, if set, do not build the parser, just parse the input grammar\n\t(default: false).\n\n\t-receiver-name=NAME : string, name of the receiver variable for the generated\n\tcode blocks. Non-initializer code blocks in the grammar end up as methods on the\n\t*current type, and this option sets the name of the receiver (default: c).\n\nThe tool makes no attempt to format the code, nor to detect the\nrequired imports. It is recommended to use goimports to properly generate\nthe output code:\n\tpigeon GRAMMAR_FILE | goimports > output_file.go\n\nThe goimports tool can be installed with:\n\tgo get golang.org\/x\/tools\/cmd\/goimports\n\nIf the code blocks in the grammar are golint- and go vet-compliant, then\nthe resulting generated code will also be golint- and go vet-compliant.\n\nThe generated code doesn't use any third-party dependency unless code blocks\nin the grammar require such a dependency.\n\nPEG syntax\n\nThe accepted syntax for the grammar is formally defined in the\ngrammar\/pigeon.peg file, using the PEG syntax. What follows is an informal\ndescription of this syntax.\n\nIdentifiers, whitespace, comments and literals follow the same\nnotation as the Go language, as defined in the language specification\n(http:\/\/golang.org\/ref\/spec#Source_code_representation):\n\n\t\/\/ single line comment*\/\n\/\/\t\/* multi-line comment *\/\n\/*\t'x' (single quotes for single char literal)\n\t\"double quotes for string literal\"\n\t`backtick quotes for raw string literal`\n\tRuleName (a valid identifier)\n\nThe grammar must be Unicode text encoded in UTF-8. New lines are identified\nby the \\n character (U+000A). Space (U+0020), horizontal tabs (U+0009) and\ncarriage returns (U+000D) are considered whitespace and are ignored except\nto separate tokens.\n\nRules\n\nA PEG grammar consists of a set of rules. A rule is an identifier followed\nby a rule definition operator and an expression. An optional display name -\na string literal used in error messages instead of the rule identifier - can\nbe specified after the rule identifier. E.g.:\n\tRuleA \"friendly name\" = 'a'+ \/\/ RuleA is one or more lowercase 'a's\n\nThe rule definition operator can be any one of those:\n\t=, <-, ← (U+2190), ⟵ (U+27F5)\n\nExpressions\n\nA rule is defined by an expression. The following sections describe the\nvarious expression types. Expressions can be grouped by using parentheses,\nand a rule can be referenced by its identifier in place of an expression.\n\nChoice expression\n\nThe choice expression is a list of expressions that will be tested in the\norder they are defined. The first one that matches will be used. Expressions\nare separated by the forward slash character \"\/\". E.g.:\n\tChoiceExpr = A \/ B \/ C \/\/ A, B and C should be rules declared in the grammar\n\nBecause the first match is used, it is important to think about the order\nof expressions. For example, in this rule, \"<=\" would never be used because\nthe \"<\" expression comes first:\n\tBadChoiceExpr = \"<\" \/ \"<=\"\n\nSequence expression\n\nThe sequence expression is a list of expressions that must all match in\nthat same order for the sequence expression to be considered a match.\nExpressions are separated by whitespace. E.g.:\n\tSeqExpr = \"A\" \"b\" \"c\" \/\/ matches \"Abc\", but not \"Acb\"\n\nLabeled expression\n\nA labeled expression consists of an identifier followed by a colon \":\"\nand an expression. A labeled expression introduces a variable named with\nthe label that can be referenced in the expression's code block.\nThe variable will have the value of the expression that follows the colon.\nE.g.:\n\tLabeledExpr = value:[a-z]+ {\n\t\tfmt.Println(value)\n\t\treturn value, nil\n\t}\n\nAnd and not expressions\n\nAn expression prefixed with the ampersand \"&\" is the \"and\" predicate\nexpression: it is considered a match if the following expression is a match,\nbut it does not consume any input.\n\nAn expression prefixed with the exclamation point \"!\" is the \"not\" predicate\nexpression: it is considered a match if the following expression is not\na match, but it does not consume any input. E.g.:\n\tAndExpr = \"A\" &\"B\" \/\/ matches \"A\" if followed by a \"B\" (does not consume \"B\")\n\tNotExpr = \"A\" !\"B\" \/\/ matches \"A\" if not followed by a \"B\" (does not consume \"B\")\n\nThe expression following the & and ! operators can be a code block. In that\ncase, the code block must return a bool and an error. The operator's semantic\nis the same, & is a match if the code block returns true, ! is a match if the\ncode block returns false. The code block has access to any labeled value\ndefined in its scope. E.g.:\n\tCodeAndExpr = value:[a-z] &{\n\t\t\/\/ can access the value local variable...\n\t\treturn true, nil\n\t}\n\nRepeating expressions\n\nAn expression followed by \"*\", \"?\" or \"+\" is a match if the expression\noccurs zero or more times (\"*\"), zero or one time \"?\" or one or more times\n(\"+\") respectively. The match is greedy, it will match as many times as\npossible. E.g.\n\tZeroOrMoreAs = \"A\"*\n\nLiteral matcher\n\nA literal matcher tries to match the input against a single character or a\nstring literal. The literal may be a single-quoted single character, a\ndouble-quoted string or a backtick-quoted raw string. The same rules as in Go\napply regarding the allowed characters and escapes.\n\nThe literal may be followed by a lowercase \"i\" (outside the ending quote)\nto indicate that the match is case-insensitive. E.g.:\n\tLiteralMatch = \"Awesome\\n\"i \/\/ matches \"awesome\" followed by a newline\n\nCharacter class matcher\n\nA character class matcher tries to match the input against a class of characters\ninside square brackets \"[...]\". Inside the brackets, characters represent\nthemselves and the same escapes as in string literals are available, except\nthat the single- and double-quote escape is not valid, instead the closing\nsquare bracket \"]\" must be escaped to be used.\n\nCharacter ranges can be specified using the \"[a-z]\" notation. Unicode\nclasses can be specified using the \"[\\pL]\" notation, where L is a\nsingle-letter Unicode class of characters, or using the \"[\\p{Class}]\"\nnotation where Class is a valid Unicode class (e.g. \"Latin\").\n\nAs for string literals, a lowercase \"i\" may follow the matcher (outside\nthe ending square bracket) to indicate that the match is case-insensitive.\nA \"^\" as first character inside the square brackets indicates that the match\nis inverted (it is a match if the input does not match the character class\nmatcher). E.g.:\n\tNotAZ = [^a-z]i\n\nAny matcher\n\nThe any matcher is represented by the dot \".\". It matches any character\nexcept the end of file, thus the \"!.\" expression is used to indicate \"match\nthe end of file\". E.g.:\n\tAnyChar = . \/\/ match a single character\n\tEOF = !.\n\nCode block\n\nCode blocks can be added to generate custom Go code. There are three kinds\nof code blocks: the initializer, the action and the predicate. All code blocks\nappear inside curly braces \"{...}\".\n\nThe initializer must appear first in the grammar, before any rule. It is\ncopied as-is (minus the wrapping curly braces) at the top of the generated\nparser. It may contain function declarations, types, variables, etc. just\nlike any Go file. Every symbol declared here will be available to all other\ncode blocks.  Although the initializer is optional in a valid grammar, it is\nusually required to generate a valid Go source code file (for the package\nclause). E.g.:\n\t{\n\t\tpackage main\n\n\t\tfunc someHelper() {\n\t\t\t\/\/ ...\n\t\t}\n\t}\n\nAction code blocks are code blocks declared after an expression in a rule.\nThose code blocks are turned into a method on the \"*current\" type in the\ngenerated source code. The method receives any labeled expression's value\nas argument (as interface{}) and must return two values, the first being\nthe value of the expression (an interface{}), and the second an error.\nIf a non-nil error is returned, it is added to the list of errors that the\nparser will return. E.g.:\n\tRuleA = \"A\"+ {\n\t\t\/\/ return the matched string, \"c\" is the default name for\n\t\t\/\/ the *current receiver variable.\n\t\treturn string(c.text), nil\n\t}\n\nPredicate code blocks are code blocks declared immediately after the and \"&\"\nor the not \"!\" operators. Like action code blocks, predicate code blocks\nare turned into a method on the \"*current\" type in the generated source code.\nThe method receives any labeled expression's value as argument (as interface{})\nand must return two values, the first being a bool and the second an error.\nIf a non-nil error is returned, it is added to the list of errors that the\nparser will return.

For example, it would be an error for the\nUser.ID field to have the type string.\n\n    users, err := db.BindModel(\"users\", User{})\n\nThe table definition is loaded from the database allowing custom\nchecks such as verifying the existence of indexes.\n\n    if users.GetKey(\"id\") == nil {\n        \/\/ The index (\"id\") does not exist!\n    }\n    if users.GetKey(\"id\", \"name\") == nil {\n        \/\/ The index (\"id\", \"name\") does not exist!\n    }\n\nCustom Types\n\nWhile fields are often primitive types such as int64 or string, it is\nsometimes desirable to use a custom type. This can be accomplished by\nhaving the type implement the sql.Scanner and driver.Valuer\ninterfaces. For example, you might create a GzippedText type which\nautomatically compresses the value when it is written to the database\nand uncompressed when it is read:\n\n    type GzippedText []byte\n    func (g GzippedText) Value() (driver.Value, error) {\n        buf := &bytes.Buffer{}\n        w := gzip.NewWriter(buf)\n        defer w.Close()\n        w.Write(g)\n        return buf.Bytes(), nil\n    }\n    func (g *GzippedText) Scan(src interface{}) error {\n        var source []byte\n        switch t := src.(type) {\n        case string:\n            source = []byte(t)\n        case []byte:\n            source = t\n        default:\n            return errors.New(\"Incompatible type for GzippedText\")\n        }\n        reader, err := gzip.NewReader(bytes.NewReader(source))\n        defer reader.Close()\n        b, err := ioutil.ReadAll(reader)\n        if err != nil {\n            return err\n        }\n        *g = GzippedText(b)\n        return nil\n    }\n\nInsert\n\nThe Insert method is used to insert one or more rows in a table.\n\n    err := db.Insert(User{ID:42, Name:\"Peter Mattis\"})\n\nYou can pass either a struct or a pointer to a struct.\n\n    err := db.Insert(&User{ID:43, Name:\"Spencer Kimball\"})\n\nMultiple rows can be inserted at once. Doing so offers convenience and\nperformance.\n\n    err := db.Insert(&User{ID:42, Name:\"Peter Mattis\"},\n        &User{ID:43, Name:\"Spencer Kimball\"})\n\nWhen multiple rows are batch inserted the returned error corresponds\nto the first SQL error encountered which may make it impossible to\ndetermine which row caused the error. If the rows correspond to\ndifferent tables the order of insertion into the tables is\nundefined. If you care about the order of insertion into multiple\ntables and determining which row is causing an insertion error,\nstructure your calls to Insert appropriately (i.e. insert into a\nsingle table or insert a single row).\n\nAfter a successful insert on a table with an auto increment primary\nkey, the auto increment will be set back in the corresponding field of\nthe object. For example, if the user table was defined as:\n\n    CREATE TABLE users (\n      id   bigint       PRIMARY KEY AUTO INCREMENT NOT NULL,\n      name varchar(767) NOT NULL,\n      INDEX (id, name)\n    )\n\nThen we could create a new user by doing:\n\n    u := &User{Name:\"Peter Mattis\"}\n    err := db.Insert(u)\n    if err != nil {\n        ...\n    }\n    \/\/ u.ID will be correctly populated at this point\n\nReplace\n\nThe Replace method replaces a row in table, either inserting the row\nif it doesn't exist, or deleting and then inserting the row. See the\nMySQL docs for the difference between REPLACE, UPDATE and INSERT ON\nDUPLICATE KEY UPDATE (Upsert).\n\n    err := db.Replace(&User{ID:42, Name:\"Peter Mattis\"})\n\nUpdate\n\nThe Update method updates a row in a table, returning the number of\nrows modified.\n\n    count, err := db.Update(&User{ID:42, Name:\"Peter Mattis\"})\n\nUpsert\n\nThe Upsert method inserts or updates a row.\n\n    err := db.Upsert(&User{ID:42, Name:\"Peter Mattis\"})\n\nGet\n\nThe Get method retrieves a single row by primary key and binds the\nresult columns to a struct.\n\n    user := &User{}\n    err := db.Get(user, 42)\n    \/\/ Returns an error if user 42 cannot be found.\n\nDelete\n\nThe delete method deletes rows by primary key.\n\n   err := db.Delete(&User{ID:42})\n\nSee the documentation for DB.Delete for performance limitations when\nbatch deleting multiple rows from a table with a primary key composed\nof multiple columns.\n\nProgrammatic SQL Construction\n\nProgrammatic construction of SQL queries prohibits SQL injection\nattacks while keeping query construction both readable and similar to\nSQL itself. Support is provided for most of the SQL DML (data\nmanipulation language), though the constructed queries are targetted\nto MySQL.\n\n    q := users.Select(\"*\").Where(users.C(\"id\").Eq(foo))\n    \/\/ q.String() == \"SELECT `users`.* FROM users WHERE `users`.`id` = 'foo'\"\n    var results []User\n    err := db.Select(&results, q)\n\nDB provides wrappers for the sql.Query and sql.QueryRow\ninterfaces. The Rows struct returned from Query has an additional\nStructScan method for binding the columns for a row result to a\nstruct.\n\n    rows, err := db.Query(q)\n    if err != nil {\n      return err\n    }\n    defer rows.Close()\n    for rows.Next() {\n      u := User{}\n      if err := rows.StructScan(&u); err != nil {\n        return err\n      }\n      \/\/ Process u\n    }\n\nQueryRow can be used to easily query and scan a single value:\n\n    var count int\n    err := db.QueryRow(users.Select(users.C(\"id\").Count())).Scan(&count)\n\nPerformance\n\nIn addition to the convenience of inserting, deleting and updating\ntable rows using a struct, attention has been paid to\nperformance. Since squalor is carefully constructing the SQL queries\nfor insertion, deletion and update, it eschews the use of placeholders\nin favor of properly escaping values in the query. With the Go MySQL\ndrivers, this saves a roundtrip to the database for each query because\nqueries with placeholders must be prepared before being executed.\n\nMarshalling and unmarshalling of data from structs utilizes\nreflection, but care is taken to minimize the use of reflection in\norder to improve performance.

For example, it would be an error for the\nUser.ID field to have the type string.\n\n    users, err := db.BindModel(\"users\", User{})\n\nThe table definition is loaded from the database allowing custom\nchecks such as verifying the existence of indexes.\n\n    if users.GetKey(\"id\") == nil {\n        \/\/ The index (\"id\") does not exist!\n    }\n    if users.GetKey(\"id\", \"name\") == nil {\n        \/\/ The index (\"id\", \"name\") does not exist!\n    }\n\nCustom Types\n\nWhile fields are often primitive types such as int64 or string, it is\nsometimes desirable to use a custom type. This can be accomplished by\nhaving the type implement the sql.Scanner and driver.Valuer\ninterfaces. For example, you might create a GzippedText type which\nautomatically compresses the value when it is written to the database\nand uncompressed when it is read:\n\n    type GzippedText []byte\n    func (g GzippedText) Value() (driver.Value, error) {\n        buf := &bytes.Buffer{}\n        w := gzip.NewWriter(buf)\n        defer w.Close()\n        w.Write(g)\n        return buf.Bytes(), nil\n    }\n    func (g *GzippedText) Scan(src interface{}) error {\n        var source []byte\n        switch t := src.(type) {\n        case string:\n            source = []byte(t)\n        case []byte:\n            source = t\n        default:\n            return errors.New(\"Incompatible type for GzippedText\")\n        }\n        reader, err := gzip.NewReader(bytes.NewReader(source))\n        defer reader.Close()\n        b, err := ioutil.ReadAll(reader)\n        if err != nil {\n            return err\n        }\n        *g = GzippedText(b)\n        return nil\n    }\n\nInsert\n\nThe Insert method is used to insert one or more rows in a table.\n\n    err := db.Insert(User{ID:42, Name:\"Peter Mattis\"})\n\nYou can pass either a struct or a pointer to a struct.\n\n    err := db.Insert(&User{ID:43, Name:\"Spencer Kimball\"})\n\nMultiple rows can be inserted at once. Doing so offers convenience and\nperformance.\n\n    err := db.Insert(&User{ID:42, Name:\"Peter Mattis\"},\n        &User{ID:43, Name:\"Spencer Kimball\"})\n\nWhen multiple rows are batch inserted the returned error corresponds\nto the first SQL error encountered which may make it impossible to\ndetermine which row caused the error. If the rows correspond to\ndifferent tables the order of insertion into the tables is\nundefined. If you care about the order of insertion into multiple\ntables and determining which row is causing an insertion error,\nstructure your calls to Insert appropriately (i.e. insert into a\nsingle table or insert a single row).\n\nAfter a successful insert on a table with an auto increment primary\nkey, the auto increment will be set back in the corresponding field of\nthe object. For example, if the user table was defined as:\n\n    CREATE TABLE users (\n      id   bigint       PRIMARY KEY AUTO INCREMENT NOT NULL,\n      name varchar(767) NOT NULL,\n      INDEX (id, name)\n    )\n\nThen we could create a new user by doing:\n\n    u := &User{Name:\"Peter Mattis\"}\n    err := db.Insert(u)\n    if err != nil {\n        ...\n    }\n    \/\/ u.ID will be correctly populated at this point\n\nReplace\n\nThe Replace method replaces a row in table, either inserting the row\nif it doesn't exist, or deleting and then inserting the row. See the\nMySQL docs for the difference between REPLACE, UPDATE and INSERT ON\nDUPLICATE KEY UPDATE (Upsert).\n\n    err := db.Replace(&User{ID:42, Name:\"Peter Mattis\"})\n\nUpdate\n\nThe Update method updates a row in a table, returning the number of\nrows modified.\n\n    count, err := db.Update(&User{ID:42, Name:\"Peter Mattis\"})\n\nUpsert\n\nThe Upsert method inserts or updates a row.\n\n    err := db.Upsert(&User{ID:42, Name:\"Peter Mattis\"})\n\nGet\n\nThe Get method retrieves a single row by primary key and binds the\nresult columns to a struct.\n\n    user := &User{}\n    err := db.Get(user, 42)\n    \/\/ Returns an error if user 42 cannot be found.\n\nDelete\n\nThe delete method deletes rows by primary key.\n\n   err := db.Delete(&User{ID:42})\n\nSee the documentation for DB.Delete for performance limitations when\nbatch deleting multiple rows from a table with a primary key composed\nof multiple columns.\n\nProgrammatic SQL Construction\n\nProgrammatic construction of SQL queries prohibits SQL injection\nattacks while keeping query construction both readable and similar to\nSQL itself. Support is provided for most of the SQL DML (data\nmanipulation language), though the constructed queries are targetted\nto MySQL.\n\n    q := users.Select(\"*\").Where(users.C(\"id\").Eq(foo))\n    \/\/ squalor.Serialize(q) == \"SELECT `users`.* FROM users WHERE `users`.`id` = 'foo'\", nil\n    var results []User\n    err := db.Select(&results, q)\n\nDB provides wrappers for the sql.Query and sql.QueryRow\ninterfaces. The Rows struct returned from Query has an additional\nStructScan method for binding the columns for a row result to a\nstruct.\n\n    rows, err := db.Query(q)\n    if err != nil {\n      return err\n    }\n    defer rows.Close()\n    for rows.Next() {\n      u := User{}\n      if err := rows.StructScan(&u); err != nil {\n        return err\n      }\n      \/\/ Process u\n    }\n\nQueryRow can be used to easily query and scan a single value:\n\n    var count int\n    err := db.QueryRow(users.Select(users.C(\"id\").Count())).Scan(&count)\n\nPerformance\n\nIn addition to the convenience of inserting, deleting and updating\ntable rows using a struct, attention has been paid to\nperformance. Since squalor is carefully constructing the SQL queries\nfor insertion, deletion and update, it eschews the use of placeholders\nin favor of properly escaping values in the query. With the Go MySQL\ndrivers, this saves a roundtrip to the database for each query because\nqueries with placeholders must be prepared before being executed.\n\nMarshalling and unmarshalling of data from structs utilizes\nreflection, but care is taken to minimize the use of reflection in\norder to improve performance. For example, reflection data for models\nis cached when the model is bound to a table.\n\nBatch operations are utilized when possible. The Delete, Insert,\nReplace, Update and Upsert operations will perform multiple operations\nper SQL statement. This can provide an order of magnitude speed\nimprovement over performing the mutations one row at a time due to\nminimizing the network overhead.\n*\/\npackage squalor\n<|endoftext|>"}

For example:\n\n\tg.Execute(func(g *gocui.Gui) error {\n\t\tv, err := g.View(\"viewname\")\n\t\tif err != nil {\n\t\t\t\/\/ handle error\n\t\t}\n\t\tv.Clear()\n\t\tfmt.Fprintln(v, \"Writing from different goroutines\")\n\t\treturn nil\n\t})\n\nBy default, gocui provides a basic edition mode. This mode can be extended\nand customized creating a new Editor and assigning it to *Gui.Editor:\n\n\ttype Editor interface {\n\t\tEdit(v *View, key Key, ch rune, mod Modifier)\n\t}\n\nDefaultEditor can be taken as example to create your own custom Editor:\n\n\tvar DefaultEditor Editor = EditorFunc(simpleEditor)\n\n\tfunc simpleEditor(v *View, key Key, ch rune, mod Modifier) {\n\t\tswitch {\n\t\tcase ch != 0 && mod == 0:\n\t\t\tv.EditWrite(ch)\n\t\tcase key == KeySpace:\n\t\t\tv.EditWrite(' ')\n\t\tcase key == KeyBackspace || key == KeyBackspace2:\n\t\t\tv.EditDelete(true)\n\t\t\/\/ ...\n\t\t}\n\t}\n\nFor more information, see the examples in folder \"_examples\/\".\n*\/\npackage gocui\n<|endoftext|>"}

All rights reserved.\n\/\/ Use of this source code is governed by a BSD-style\n\/\/ license that can be found in the LICENSE file.\n\n\/*\nPackage signal implements access to incoming signals.\n\nSignals are primarily used on Unix-like systems. For the use of this\npackage on Windows and Plan 9, see below.\n\nTypes of signals\n\nThe signals SIGKILL and SIGSTOP may not be caught by a program, and\ntherefore can not be affected by this package.\n\nSynchronous signals are signals triggered by errors in program\nexecution: SIGBUS, SIGFPE, and SIGSEGV. These are only considered\nsynchronous when caused by program execution, not when sent using\nos.Process.Kill or the kill program or some similar mechanism. In\ngeneral, except as discussed below, Go programs will convert a\nsynchronous signal into a run-time panic.\n\nThe remaining signals are asynchronous signals. They are not\ntriggered by program errors, but are instead sent from the kernel or\nfrom some other program.\n\nOf the asynchronous signals, the SIGHUP signal is sent when a program\nloses its controlling terminal. The SIGINT signal is sent when the\nuser at the controlling terminal presses the interrupt character,\nwhich by default is ^C (Control-C). The SIGQUIT signal is sent when\nthe user at the controlling terminal presses the quit character, which\nby default is ^\\ (Control-Backslash). In general you can cause a\nprogram to simply exit by pressing ^C, and you can cause it to exit\nwith a stack dump by pressing ^\\.\n\nDefault behavior of signals in Go programs\n\nBy default, a synchronous signal is converted into a run-time panic. A\nSIGHUP, SIGINT, or SIGTERM signal causes the program to exit. A\nSIGQUIT, SIGILL, SIGTRAP, SIGABRT, SIGSTKFLT, SIGEMT, or SIGSYS signal\ncauses the program to exit with a stack dump. A SIGTSTP, SIGTTIN, or\nSIGTTOU signal gets the system default behavior (these signals are\nused by the shell for job control). The SIGPROF signal is handled\ndirectly by the Go runtime to implement runtime.CPUProfile. Other\nsignals are ignored.\n\nIf the Go program is started with either SIGHUP or SIGINT ignored,\nthey will remain ignored. Go always registers a handler for the other\nsignals.\n\nIf the Go program is started with a non-empty signal mask, that will\ngenerally be honored. However, some signals are explicitly unblocked:\nthe synchronous signals, SIGILL, SIGTRAP, SIGSTKFLT, SIGCHLD, SIGPROF,\nand, on GNU\/Linux, signals 32 (SIGCANCEL) and 33 (SIGSETXID)\n(SIGCANCEL and SIGSETXID are used internally by glibc).\n\nChanging the behavior of signals in Go programs\n\nThe functions in this package allow a program to change the way Go\nprograms handle signals.\n\nNotify disables the default behavior for a given set of asynchronous\nsignals and instead delivers them over one or more registered\nchannels. Specifically, it applies to the signals SIGHUP, SIGINT,\nSIGQUIT, SIGABRT, and SIGTERM. It also applies to the job control\nsignals SIGTSTP, SIGTTIN, and SIGTTOU, in which case the system\ndefault behavior does not occur. It also applies to some signals that\nare otherwise ignored: SIGUSR1, SIGUSR2, SIGPIPE, SIGALRM, SIGCHLD,\nSIGURG, SIGXCPU, SIGXFSZ, SIGVTALRM, SIGWINCH, SIGIO, SIGPWR, SIGSYS,\nSIGINFO, SIGTHR, SIGWAITING, SIGLWP, SIGFREEZE, SIGTHAW, SIGLOST,\nSIGXRES, SIGJVM1, SIGJVM2, and any real time signals used on the\nsystem. Note that not all of these signals are available on all\nsystems.\n\nIf the program was started with SIGHUP or SIGINT ignored, and Notify\nis called for either signal, a signal handler will be installed for\nthat signal and it will no longer be ignored. If, later, Reset or\nIgnore is called for that signal, or Stop is called on all channels\npassed to Notify for that signal, the signal will once again be\nignored. Reset will restore the system default behavior for the\nsignal, while Ignore will cause the system to ignore the signal\nentirely.\n\nIf the program is started with a non-empty signal mask, some signals\nwill be explicitly unblocked as described above. If Notify is called\nfor a blocked signal, it will be unblocked. If, later, Reset is\ncalled for that signal, or Stop is called on all channels passed to\nNotify for that signal, the signal will once again be blocked.\n\nSIGPIPE\n\nWhen a Go program receives an EPIPE error from the kernel while\nwriting to file descriptors 1 or 2 (standard output or standard\nerror), it will raise a SIGPIPE signal.  If the program is not\ncurrently receiving SIGPIPE via a call to Notify, this will cause the\nprogram to exit with SIGPIPE.  On descriptors other than 1 or 2, the\nwrite will return the EPIPE error.  This means that, by default,\ncommand line programs will behave like typical Unix command line\nprograms, while other programs will not crash with SIGPIPE when\nwriting to a closed network connection.\n\nGo programs that use cgo or SWIG\n\nIn a Go program that includes non-Go code, typically C\/C++ code\naccessed using cgo or SWIG, Go's startup code normally runs first. It\nconfigures the signal handlers as expected by the Go runtime, before\nthe non-Go startup code runs. If the non-Go startup code wishes to\ninstall its own signal handlers, it must take certain steps to keep Go\nworking well. This section documents those steps and the overall\neffect changes to signal handler settings by the non-Go code can have\non Go programs. In rare cases, the non-Go code may run before the Go\ncode, in which case the next section also applies.\n\nIf the non-Go code called by the Go program does not change any signal\nhandlers or masks, then the behavior is the same as for a pure Go\nprogram.\n\nIf the non-Go code installs any signal handlers, it must use the\nSA_ONSTACK flag with sigaction. Failing to do so is likely to cause\nthe program to crash if the signal is received. Go programs routinely\nrun with a limited stack, and therefore set up an alternate signal\nstack. Also, the Go standard library expects that any signal handlers\nwill use the SA_RESTART flag. Failing to do so may cause some library\ncalls to return \"interrupted system call\" errors.\n\nIf the non-Go code installs a signal handler for any of the\nsynchronous signals (SIGBUS, SIGFPE, SIGSEGV), then it should record\nthe existing Go signal handler. If those signals occur while\nexecuting Go code, it should invoke the Go signal handler (whether the\nsignal occurs while executing Go code can be determined by looking at\nthe PC passed to the signal handler). Otherwise some Go run-time\npanics will not occur as expected.\n\nIf the non-Go code installs a signal handler for any of the\nasynchronous signals, it may invoke the Go signal handler or not as it\nchooses. Naturally, if it does not invoke the Go signal handler, the\nGo behavior described above will not occur. This can be an issue with\nthe SIGPROF signal in particular.\n\nThe non-Go code should not change the signal mask on any threads\ncreated by the Go runtime. If the non-Go code starts new threads of\nits own, it may set the signal mask as it pleases.\n\nIf the non-Go code starts a new thread, changes the signal mask, and\nthen invokes a Go function in that thread, the Go runtime will\nautomatically unblock certain signals: the synchronous signals,\nSIGILL, SIGTRAP, SIGSTKFLT, SIGCHLD, SIGPROF, SIGCANCEL, and\nSIGSETXID. When the Go function returns, the non-Go signal mask will\nbe restored.\n\nIf the Go signal handler is invoked on a non-Go thread not running Go\ncode, the handler generally forwards the signal to the non-Go code, as\nfollows. If the signal is SIGPROF, the Go handler does\nnothing. Otherwise, the Go handler removes itself, unblocks the\nsignal, and raises it again, to invoke any non-Go handler or default\nsystem handler. If the program does not exit, the Go handler then\nreinstalls itself and continues execution of the program.\n\nNon-Go programs that call Go code\n\nWhen Go code is built with options like -buildmode=c-shared, it will\nbe run as part of an existing non-Go program. The non-Go code may\nhave already installed signal handlers when the Go code starts (that\nmay also happen in unusual cases when using cgo or SWIG; in that case,\nthe discussion here applies).\n\nIf the Go runtime sees an existing signal handler for the SIGCANCEL or\nSIGSETXID signals (which are used only on GNU\/Linux), it will turn on\nthe SA_ONSTACK flag and otherwise keep the signal handler.\n\nFor the synchronous signals, the Go runtime will install a signal\nhandler. It will save any existing signal handler. If a synchronous\nsignal arrives while executing non-Go code, the Go runtime will invoke\nthe existing signal handler instead of the Go signal handler.\n\nGo code built with -buildmode=c-archive or -buildmode=c-shared will\nnot install any other signal handlers by default. If there is an\nexisting signal handler, the Go runtime will turn on the SA_ONSTACK\nflag and otherwise keep the signal handler. If Notify is called for an\nasynchronous signal, a Go signal handler will be installed for that\nsignal. If, later, Reset is called for that signal, the original\nhandling for that signal will be reinstalled, restoring the non-Go\nsignal handler if any.\n\nGo code built without -buildmode=c-archive or -buildmode=c-shared will\ninstall a signal handler for the asynchronous signals listed above,\nand save any existing signal handler. If a signal is delivered to a\nnon-Go thread, it will act as described above, except that if there is\nan existing non-Go signal handler, that handler will be installed\nbefore raising the signal.\n\nWindows\n\nOn Windows a ^C (Control-C) or ^BREAK (Control-Break) normally cause\nthe program to exit. If Notify is called for os.SIGINT, ^C or ^BREAK\nwill cause os.SIGINT to be sent on the channel, and the program will\nnot exit. If Reset is called, or Stop is called on all channels passed\nto Notify, then the default behavior will be restored.\n\nPlan 9\n\nOn Plan 9, signals have type syscall.Note, which is a string. Calling\nNotify with a syscall.Note will cause that value to be sent on the\nchannel when that string is posted as a note.\n\n*\/\npackage signal\n<commit_msg>os\/signal: clarify signal doc<commit_after>\/\/ Copyright 2015 The Go Authors.

Subprocesses\nstarted by os.Exec, or by the os\/exec package, will inherit the\nmodified signal mask.\n\nChanging the behavior of signals in Go programs\n\nThe functions in this package allow a program to change the way Go\nprograms handle signals.\n\nNotify disables the default behavior for a given set of asynchronous\nsignals and instead delivers them over one or more registered\nchannels. Specifically, it applies to the signals SIGHUP, SIGINT,\nSIGQUIT, SIGABRT, and SIGTERM. It also applies to the job control\nsignals SIGTSTP, SIGTTIN, and SIGTTOU, in which case the system\ndefault behavior does not occur. It also applies to some signals that\notherwise cause no action: SIGUSR1, SIGUSR2, SIGPIPE, SIGALRM,\nSIGCHLD, SIGCONT, SIGURG, SIGXCPU, SIGXFSZ, SIGVTALRM, SIGWINCH,\nSIGIO, SIGPWR, SIGSYS, SIGINFO, SIGTHR, SIGWAITING, SIGLWP, SIGFREEZE,\nSIGTHAW, SIGLOST, SIGXRES, SIGJVM1, SIGJVM2, and any real time signals\nused on the system. Note that not all of these signals are available\non all systems.\n\nIf the program was started with SIGHUP or SIGINT ignored, and Notify\nis called for either signal, a signal handler will be installed for\nthat signal and it will no longer be ignored. If, later, Reset or\nIgnore is called for that signal, or Stop is called on all channels\npassed to Notify for that signal, the signal will once again be\nignored. Reset will restore the system default behavior for the\nsignal, while Ignore will cause the system to ignore the signal\nentirely.\n\nIf the program is started with a non-empty signal mask, some signals\nwill be explicitly unblocked as described above. If Notify is called\nfor a blocked signal, it will be unblocked. If, later, Reset is\ncalled for that signal, or Stop is called on all channels passed to\nNotify for that signal, the signal will once again be blocked.\n\nSIGPIPE\n\nWhen a Go program writes to a broken pipe, the kernel will raise a\nSIGPIPE signal.\n\nIf the program has not called Notify to receive SIGPIPE signals, then\nthe behavior depends on the file descriptor number. A write to a\nbroken pipe on file descriptors 1 or 2 (standard output or standard\nerror) will cause the program to exit with a SIGPIPE signal. A write\nto a broken pipe on some other file descriptor will take no action on\nthe SIGPIPE signal, and the write will fail with an EPIPE error.\n\nIf the program has called Notify to receive SIGPIPE signals, the file\ndescriptor number does not matter. The SIGPIPE signal will be\ndelivered to the Notify channel, and the write will fail with an EPIPE\nerror.\n\nThis means that, by default, command line programs will behave like\ntypical Unix command line programs, while other programs will not\ncrash with SIGPIPE when writing to a closed network connection.\n\nGo programs that use cgo or SWIG\n\nIn a Go program that includes non-Go code, typically C\/C++ code\naccessed using cgo or SWIG, Go's startup code normally runs first. It\nconfigures the signal handlers as expected by the Go runtime, before\nthe non-Go startup code runs. If the non-Go startup code wishes to\ninstall its own signal handlers, it must take certain steps to keep Go\nworking well. This section documents those steps and the overall\neffect changes to signal handler settings by the non-Go code can have\non Go programs. In rare cases, the non-Go code may run before the Go\ncode, in which case the next section also applies.\n\nIf the non-Go code called by the Go program does not change any signal\nhandlers or masks, then the behavior is the same as for a pure Go\nprogram.\n\nIf the non-Go code installs any signal handlers, it must use the\nSA_ONSTACK flag with sigaction. Failing to do so is likely to cause\nthe program to crash if the signal is received. Go programs routinely\nrun with a limited stack, and therefore set up an alternate signal\nstack. Also, the Go standard library expects that any signal handlers\nwill use the SA_RESTART flag. Failing to do so may cause some library\ncalls to return \"interrupted system call\" errors.\n\nIf the non-Go code installs a signal handler for any of the\nsynchronous signals (SIGBUS, SIGFPE, SIGSEGV), then it should record\nthe existing Go signal handler. If those signals occur while\nexecuting Go code, it should invoke the Go signal handler (whether the\nsignal occurs while executing Go code can be determined by looking at\nthe PC passed to the signal handler). Otherwise some Go run-time\npanics will not occur as expected.\n\nIf the non-Go code installs a signal handler for any of the\nasynchronous signals, it may invoke the Go signal handler or not as it\nchooses. Naturally, if it does not invoke the Go signal handler, the\nGo behavior described above will not occur. This can be an issue with\nthe SIGPROF signal in particular.\n\nThe non-Go code should not change the signal mask on any threads\ncreated by the Go runtime. If the non-Go code starts new threads of\nits own, it may set the signal mask as it pleases.\n\nIf the non-Go code starts a new thread, changes the signal mask, and\nthen invokes a Go function in that thread, the Go runtime will\nautomatically unblock certain signals: the synchronous signals,\nSIGILL, SIGTRAP, SIGSTKFLT, SIGCHLD, SIGPROF, SIGCANCEL, and\nSIGSETXID. When the Go function returns, the non-Go signal mask will\nbe restored.\n\nIf the Go signal handler is invoked on a non-Go thread not running Go\ncode, the handler generally forwards the signal to the non-Go code, as\nfollows. If the signal is SIGPROF, the Go handler does\nnothing. Otherwise, the Go handler removes itself, unblocks the\nsignal, and raises it again, to invoke any non-Go handler or default\nsystem handler. If the program does not exit, the Go handler then\nreinstalls itself and continues execution of the program.\n\nNon-Go programs that call Go code\n\nWhen Go code is built with options like -buildmode=c-shared, it will\nbe run as part of an existing non-Go program. The non-Go code may\nhave already installed signal handlers when the Go code starts (that\nmay also happen in unusual cases when using cgo or SWIG; in that case,\nthe discussion here applies).\n\nIf the Go runtime sees an existing signal handler for the SIGCANCEL or\nSIGSETXID signals (which are used only on GNU\/Linux), it will turn on\nthe SA_ONSTACK flag and otherwise keep the signal handler.\n\nFor the synchronous signals, the Go runtime will install a signal\nhandler. It will save any existing signal handler. If a synchronous\nsignal arrives while executing non-Go code, the Go runtime will invoke\nthe existing signal handler instead of the Go signal handler.\n\nGo code built with -buildmode=c-archive or -buildmode=c-shared will\nnot install any other signal handlers by default. If there is an\nexisting signal handler, the Go runtime will turn on the SA_ONSTACK\nflag and otherwise keep the signal handler. If Notify is called for an\nasynchronous signal, a Go signal handler will be installed for that\nsignal. If, later, Reset is called for that signal, the original\nhandling for that signal will be reinstalled, restoring the non-Go\nsignal handler if any.\n\nGo code built without -buildmode=c-archive or -buildmode=c-shared will\ninstall a signal handler for the asynchronous signals listed above,\nand save any existing signal handler. If a signal is delivered to a\nnon-Go thread, it will act as described above, except that if there is\nan existing non-Go signal handler, that handler will be installed\nbefore raising the signal.\n\nWindows\n\nOn Windows a ^C (Control-C) or ^BREAK (Control-Break) normally cause\nthe program to exit. If Notify is called for os.SIGINT, ^C or ^BREAK\nwill cause os.SIGINT to be sent on the channel, and the program will\nnot exit. If Reset is called, or Stop is called on all channels passed\nto Notify, then the default behavior will be restored.\n\nPlan 9\n\nOn Plan 9, signals have type syscall.Note, which is a string. Calling\nNotify with a syscall.Note will cause that value to be sent on the\nchannel when that string is posted as a note.\n\n*\/\npackage signal\n<|endoftext|>"}

See the documentation for type LoadMode\nfor details.\n\nMost tools should pass their command-line arguments (after any flags)\nuninterpreted to the loader, so that the loader can interpret them\naccording to the conventions of the underlying build system.\nSee the Example function for typical usage.\n\n*\/\npackage packages \/\/ import \"golang.org\/x\/tools\/go\/packages\"\n\n\/*\n\nMotivation and design considerations\n\nThe new package's design solves problems addressed by two existing\npackages: go\/build, which locates and describes packages, and\ngolang.org\/x\/tools\/go\/loader, which loads, parses and type-checks them.\nThe go\/build.Package structure encodes too much of the 'go build' way\nof organizing projects, leaving us in need of a data type that describes a\npackage of Go source code independent of the underlying build system.\nWe wanted something that works equally well with go build and vgo, and\nalso other build systems such as Bazel and Blaze, making it possible to\nconstruct analysis tools that work in all these environments.\nTools such as errcheck and staticcheck were essentially unavailable to\nthe Go community at Google, and some of Google's internal tools for Go\nare unavailable externally.\nThis new package provides a uniform way to obtain package metadata by\nquerying each of these build systems, optionally supporting their\npreferred command-line notations for packages, so that tools integrate\nneatly with users' build environments. The Metadata query function\nexecutes an external query tool appropriate to the current workspace.\n\nLoading packages always returns the complete import graph \"all the way down\",\neven if all you want is information about a single package, because the query\nmechanisms of all the build systems we currently support ({go,vgo} list, and\nblaze\/bazel aspect-based query) cannot provide detailed information\nabout one package without visiting all its dependencies too, so there is\nno additional asymptotic cost to providing transitive information.\n(This property might not be true of a hypothetical 5th build system.)\n\nIn calls to TypeCheck, all initial packages, and any package that\ntransitively depends on one of them, must be loaded from source.\nConsider A->B->C->D->E: if A,C are initial, A,B,C must be loaded from\nsource; D may be loaded from export data, and E may not be loaded at all\n(though it's possible that D's export data mentions it, so a\ntypes.Package may be created for it and exposed.)\n\nThe old loader had a feature to suppress type-checking of function\nbodies on a per-package basis, primarily intended to reduce the work of\nobtaining type information for imported packages. Now that imports are\nsatisfied by export data, the optimization no longer seems necessary.\n\nDespite some early attempts, the old loader did not exploit export data,\ninstead always using the equivalent of WholeProgram mode. This was due\nto the complexity of mixing source and export data packages (now\nresolved by the upward traversal mentioned above), and because export data\nfiles were nearly always missing or stale. Now that 'go build' supports\ncaching, all the underlying build systems can guarantee to produce\nexport data in a reasonable (amortized) time.\n\nTest \"main\" packages synthesized by the build system are now reported as\nfirst-class packages, avoiding the need for clients (such as go\/ssa) to\nreinvent this generation logic.\n\nOne way in which go\/packages is simpler than the old loader is in its\ntreatment of in-package tests. In-package tests are packages that\nconsist of all the files of the library under test, plus the test files.\nThe old loader constructed in-package tests by a two-phase process of\nmutation called \"augmentation\": first it would construct and type check\nall the ordinary library packages and type-check the packages that\ndepend on them; then it would add more (test) files to the package and\ntype-check again. This two-phase approach had four major problems:\n1) in processing the tests, the loader modified the library package,\n   leaving no way for a client application to see both the test\n   package and the library package; one would mutate into the other.\n2) because test files can declare additional methods on types defined in\n   the library portion of the package, the dispatch of method calls in\n   the library portion was affected by the presence of the test files.\n   This should have been a clue that the packages were logically\n   different.\n3) this model of \"augmentation\" assumed at most one in-package test\n   per library package, which is true of projects using 'go build',\n   but not other build systems.\n4) because of the two-phase nature of test processing, all packages that\n   import the library package had to be processed before augmentation,\n   forcing a \"one-shot\" API and preventing the client from calling Load\n   in several times in sequence as is now possible in WholeProgram mode.\n   (TypeCheck mode has a similar one-shot restriction for a different reason.)\n\nEarly drafts of this package supported \"multi-shot\" operation.\nAlthough it allowed clients to make a sequence of calls (or concurrent\ncalls) to Load, building up the graph of Packages incrementally,\nit was of marginal value: it complicated the API\n(since it allowed some options to vary across calls but not others),\nit complicated the implementation,\nit cannot be made to work in Types mode, as explained above,\nand it was less efficient than making one combined call (when this is possible).\nAmong the clients we have inspected, none made multiple calls to load\nbut could not be easily and satisfactorily modified to make only a single call.\nHowever, applications changes may be required.\nFor example, the ssadump command loads the user-specified packages\nand in addition the runtime package.  It is tempting to simply append\n\"runtime\" to the user-provided list, but that does not work if the user\nspecified an ad-hoc package such as [a.go b.go].\nInstead, ssadump no longer requests the runtime package,\nbut seeks it among the dependencies of the user-specified packages,\nand emits an error if it is not found.\n\nOverlays: The Overlay field in the Config allows providing alternate contents\nfor Go source files, by providing a mapping from file path to contents.\ngo\/packages will pull in new imports added in overlay files when go\/packages\nis run in LoadImports mode or greater.\nOverlay support for the go list driver isn't complete yet: if the file doesn't\nexist on disk, it will only be recognized in an overlay if it is a non-test file\nand the package would be reported even without the overlay.\n\nQuestions & Tasks\n\n- Add GOARCH\/GOOS?\n  They are not portable concepts, but could be made portable.\n  Our goal has been to allow users to express themselves using the conventions\n  of the underlying build system: if the build system honors GOARCH\n  during a build and during a metadata query, then so should\n  applications built atop that query mechanism.\n  Conversely, if the target architecture of the build is determined by\n  command-line flags, the application can pass the relevant\n  flags through to the build system using a command such as:\n    myapp -query_flag=\"--cpu=amd64\" -query_flag=\"--os=darwin\"\n  However, this approach is low-level, unwieldy, and non-portable.\n  GOOS and GOARCH seem important enough to warrant a dedicated option.\n\n- How should we handle partial failures such as a mixture of good and\n  malformed patterns, existing and non-existent packages, successful and\n  failed builds, import failures, import cycles, and so on, in a call to\n  Load?\n\n- Support bazel, blaze, and go1.10 list, not just go1.11 list.\n\n- Handle (and test) various partial success cases, e.g.\n  a mixture of good packages and:\n  invalid patterns\n  nonexistent packages\n  empty packages\n  packages with malformed package or import declarations\n  unreadable files\n  import cycles\n  other parse errors\n  type errors\n  Make sure we record errors at the correct place in the graph.\n\n- Missing packages among initial arguments are not reported.\n  Return bogus packages for them, like golist does.\n\n- \"undeclared name\" errors (for example) are reported out of source file\n  order. I suspect this is due to the breadth-first resolution now used\n  by go\/types. Is that a bug?

This two-phase approach had four major problems:\n1) in processing the tests, the loader modified the library package,\n   leaving no way for a client application to see both the test\n   package and the library package; one would mutate into the other.\n2) because test files can declare additional methods on types defined in\n   the library portion of the package, the dispatch of method calls in\n   the library portion was affected by the presence of the test files.\n   This should have been a clue that the packages were logically\n   different.\n3) this model of \"augmentation\" assumed at most one in-package test\n   per library package, which is true of projects using 'go build',\n   but not other build systems.\n4) because of the two-phase nature of test processing, all packages that\n   import the library package had to be processed before augmentation,\n   forcing a \"one-shot\" API and preventing the client from calling Load\n   in several times in sequence as is now possible in WholeProgram mode.\n   (TypeCheck mode has a similar one-shot restriction for a different reason.)\n\nEarly drafts of this package supported \"multi-shot\" operation.\nAlthough it allowed clients to make a sequence of calls (or concurrent\ncalls) to Load, building up the graph of Packages incrementally,\nit was of marginal value: it complicated the API\n(since it allowed some options to vary across calls but not others),\nit complicated the implementation,\nit cannot be made to work in Types mode, as explained above,\nand it was less efficient than making one combined call (when this is possible).\nAmong the clients we have inspected, none made multiple calls to load\nbut could not be easily and satisfactorily modified to make only a single call.\nHowever, applications changes may be required.\nFor example, the ssadump command loads the user-specified packages\nand in addition the runtime package.  It is tempting to simply append\n\"runtime\" to the user-provided list, but that does not work if the user\nspecified an ad-hoc package such as [a.go b.go].\nInstead, ssadump no longer requests the runtime package,\nbut seeks it among the dependencies of the user-specified packages,\nand emits an error if it is not found.\n\nOverlays: The Overlay field in the Config allows providing alternate contents\nfor Go source files, by providing a mapping from file path to contents.\ngo\/packages will pull in new imports added in overlay files when go\/packages\nis run in LoadImports mode or greater.\nOverlay support for the go list driver isn't complete yet: if the file doesn't\nexist on disk, it will only be recognized in an overlay if it is a non-test file\nand the package would be reported even without the overlay.\n\nQuestions & Tasks\n\n- Add GOARCH\/GOOS?\n  They are not portable concepts, but could be made portable.\n  Our goal has been to allow users to express themselves using the conventions\n  of the underlying build system: if the build system honors GOARCH\n  during a build and during a metadata query, then so should\n  applications built atop that query mechanism.\n  Conversely, if the target architecture of the build is determined by\n  command-line flags, the application can pass the relevant\n  flags through to the build system using a command such as:\n    myapp -query_flag=\"--cpu=amd64\" -query_flag=\"--os=darwin\"\n  However, this approach is low-level, unwieldy, and non-portable.\n  GOOS and GOARCH seem important enough to warrant a dedicated option.\n\n- How should we handle partial failures such as a mixture of good and\n  malformed patterns, existing and non-existent packages, successful and\n  failed builds, import failures, import cycles, and so on, in a call to\n  Load?\n\n- Support bazel, blaze, and go1.10 list, not just go1.11 list.\n\n- Handle (and test) various partial success cases, e.g.\n  a mixture of good packages and:\n  invalid patterns\n  nonexistent packages\n  empty packages\n  packages with malformed package or import declarations\n  unreadable files\n  import cycles\n  other parse errors\n  type errors\n  Make sure we record errors at the correct place in the graph.\n\n- Missing packages among initial arguments are not reported.\n  Return bogus packages for them, like golist does.\n\n- \"undeclared name\" errors (for example) are reported out of source file\n  order. I suspect this is due to the breadth-first resolution now used\n  by go\/types. Is that a bug? Discuss with gri.\n\n*\/\n<|endoftext|>"}
