The uses and syntax of these files are described in the config and ioc packages respectively.\n\nComponents and configuration\n\nA Granitic application needs two things to start:\n\n1. A list of components to host in its IoC container.\n\n2. One or more JSON configuration files containing environment-specific settings for your application (passwords, hostnames etc.)\n\nConfiguration files\n\nFolders and files containing configuration are by default expected to be stored in\n\n\tresource\/config\n\nThis folder can contain any number of files or sub-directories. This location can be overridden by using the -c argument\nwhen starting your application from the command line. This argument is expected to be a comma separated list of file paths,\ndirectories or HTTP URLs to JSON files or any mixture of the above.\n\nCommand line arguments\n\nWhen starting your application from the command, Granitic takes control of processing command line arguments. By\ndefault your application will support the following arguments.\n\n\t-c A comma separated list of files, directories or HTTP URIs in any combination (default resource\/config)\n\t-l The level of messages that will be logged by the framework while bootstrapping (before logging configuration is loaded; default INFO)\n\t-i An optional string that can be used to uniquely identify this instance of your application\n\nIf your application needs to perform command line processing and you want to prevent Granitic from attempting to parse command line arguments,\nyou should start Granitic using the alternative:\n\n\tStartGraniticWithSettings(cs *ioc.ProtoComponents, is *config.InitialSettings)\n\nwhere you are expected to programmatically define the initial settings.\n\n*\/\npackage granitic\n\nimport (\n\t\"bytes\"\n\t\"encoding\/base64\"\n\t\"encoding\/gob\"\n\t\"github.com\/graniticio\/granitic\/v2\/config\"\n\t\"github.com\/graniticio\/granitic\/v2\/facility\"\n\t\"github.com\/graniticio\/granitic\/v2\/instance\"\n\t\"github.com\/graniticio\/granitic\/v2\/ioc\"\n\t\"github.com\/graniticio\/granitic\/v2\/logging\"\n\t\"os\"\n\t\"os\/signal\"\n\t\"runtime\"\n\t\"syscall\"\n\t\"time\"\n)\n\nconst (\n\t\/\/Version is the semantic version number for this version of Granitic\n\tVersion = \"2.0.3\"\n\tinitiatorComponentName string = instance.FrameworkPrefix + \"Init\"\n\tsystemPath = \"System\"\n\tconfigAccessorComponentName string = instance.FrameworkPrefix + \"Accessor\"\n\tinstanceIDDecoratorName = instance.FrameworkPrefix + \"InstanceIDDecorator\"\n)\n\n\/\/ StartGranitic starts the IoC container and populates it with the supplied list of prototype components.

behavior.<\/li>\n <li><b>Name collision detection is overly conservative.<\/b> If renaming\n will introduce shadowing, this is reported as an error, even if it will not\n change the program's

Registerisation of eligible locals and φ-node insertion\n\/\/ using dominance and dataflow are then performed as a second pass\n\/\/ called \"lifting\" to improve the accuracy and performance of\n\/\/ subsequent analyses; this pass can be skipped by setting the\n\/\/ NaiveForm builder flag.\n\/\/\n\/\/ The primary interfaces of this package are:\n\/\/\n\/\/ - Member: a named member of a Go package.\n\/\/ - Value: an expression that yields a value.\n\/\/ - Instruction: a statement that consumes values and performs computation.\n\/\/ - Node: a Value or Instruction (emphasizing its membership in the SSA value graph)\n\/\/\n\/\/ A computation that yields a result implements both the Value and\n\/\/ Instruction interfaces. The following table shows for each\n\/\/ concrete type which of these interfaces it implements.\n\/\/\n\/\/ Value? Instruction? Member?\n\/\/ *Alloc ✔ ✔\n\/\/ *BinOp ✔ ✔\n\/\/ *Builtin ✔\n\/\/ *Call ✔ ✔\n\/\/ *ChangeInterface ✔ ✔\n\/\/ *ChangeType ✔ ✔\n\/\/ *Const ✔\n\/\/ *Convert ✔ ✔\n\/\/ *DebugRef ✔\n\/\/ *Defer ✔\n\/\/ *Extract ✔ ✔\n\/\/ *Field ✔ ✔\n\/\/ *FieldAddr ✔ ✔\n\/\/ *FreeVar ✔\n\/\/ *Function ✔ ✔ (func)\n\/\/ *Global ✔ ✔ (var)\n\/\/ *Go ✔\n\/\/ *If ✔\n\/\/ *Index ✔ ✔\n\/\/ *IndexAddr ✔ ✔\n\/\/ *Jump ✔\n\/\/ *Lookup ✔ ✔\n\/\/ *MakeChan ✔ ✔\n\/\/ *MakeClosure ✔ ✔\n\/\/ *MakeInterface ✔ ✔\n\/\/ *MakeMap ✔ ✔\n\/\/ *MakeSlice ✔ ✔\n\/\/ *MapUpdate ✔\n\/\/ *NamedConst ✔ (const)\n\/\/ *Next ✔ ✔\n\/\/ *Panic ✔\n\/\/ *Parameter ✔\n\/\/ *Phi ✔ ✔\n\/\/ *Range ✔ ✔\n\/\/ *Return ✔\n\/\/ *RunDefers ✔\n\/\/ *Select ✔ ✔\n\/\/ *Send ✔\n\/\/ *Slice ✔ ✔\n\/\/ *SliceToArrayPointer ✔ ✔\n\/\/ *Store ✔\n\/\/ *Type ✔ (type)\n\/\/ *TypeAssert ✔ ✔\n\/\/ *UnOp ✔ ✔\n\/\/\n\/\/ Other key types in this package include: Program, Package, Function\n\/\/ and BasicBlock.\n\/\/\n\/\/ The program representation constructed by this package is fully\n\/\/ resolved internally, i.e. it does not rely on the names of Values,\n\/\/ Packages, Functions, Types or BasicBlocks for the correct\n\/\/ interpretation of the program. Only the identities of objects and\n\/\/ the topology of the SSA and type graphs are semantically\n\/\/ significant. (There is one exception: Ids, used to identify field\n\/\/ and method names, contain strings.) Avoidance of name-based\n\/\/ operations simplifies the implementation of subsequent passes and\n\/\/ can make them very efficient. Many objects are nonetheless named\n\/\/ to aid in debugging, but it is not essential that the names be\n\/\/ either accurate or unambiguous. The public API exposes a number of\n\/\/ name-based maps for client convenience.\n\/\/\n\/\/ The ssa\/ssautil package provides various utilities that depend only\n\/\/ on the public API of this package.\n\/\/\n\/\/ TODO(adonovan): Consider the exceptional control-flow implications\n\/\/ of defer and recover().\n\/\/\n\/\/ TODO(adonovan): write a how-to document for all the various cases\n\/\/ of trying to determine corresponding elements across the four\n\/\/ domains of source locations, ast.Nodes, types.Objects,\n\/\/ ssa.Values\/Instructions.\n\/\/\npackage ssa \/\/ import

An example\ncan be found in gonew.json.example The configuration file specifies\nenvironments, projects, and the locations of externally defined templates. An\nenvironment holds information used in template rendering like user metadata and\nimport paths for created projects. A project configuration describes the files\ncontained in a project and script hooks to execute on file creation.\nEnvironments can inherit\/override other environments and projects can\ninherit\/override from other projects.\n\nCustom Templates\n\nUsers can define their own set of custom templates. This is done by adding\nentries to the ExternalTemplates array in the configuration file. Templates\ncan make use of the standard gonew templates (in the \"templates\" directory).\nTemplates must have the .t2 file extension to be recognized by Gonew.\n\nTemplate Functions\n\nTemplates in Gonew have acces to a small library of helper functions Here is\nlist of all available template functions.\n\n\tname: the user's name specified in the environment\n\temail: the user's email specified

The plain docker\n\/\/ build is somewhat limiting due to the resulting image that is a superset composition of\n\/\/ the build-time and run-time environments.

The gossip rate is tunable, and can be disabled.\n\nA Push\/Pull mechanism is also included because it allows new nodes to\nget an almost complete member list upon joining.

It is loosely\nbased on the SWIM paper (Scalable Weakly-consistent Infection-style\nprocess group Membership protocol). There are a few notable differences,\nincluding the uses of additional gossip (instead of purely piggybacking on\nfailure detection) and the addition of a state push\/pull mechanism.\n\nAn independent gossip mechanism is used because it allows for changes to be propogated\nmore quickly, and also enables us to gossip at a different interval that we perform\nfailure checks. The gossip rate is tunable, and can be disabled.\n\nA Push\/Pull mechanism is also included because it allows new nodes to\nget an almost complete member list upon joining. It also is used as\na periodic anti-entropy mechanism to ensure very high convergence rates.\nThe frequency of this can be adjusted to change the overhead, or disabled\nentirely.\n\n*\/\npackage memberlist\n\nimport (\n\t\"fmt\"\n\t\"log\"\n\t\"net\"\n\t\"os\"\n\t\"sync\"\n\t\"time\"\n)\n\ntype Delegate interface {\n\t\/\/ NodeMeta is used to retrieve meta-data about the current node\n\t\/\/ when broadcasting an alive message.

authenticate with Vault without\nhaving to store passwords outside of Vault. It is a single method of\nsolving the chicken-and-egg problem of setting up Vault access on a machine.\nWith this provider, nobody except the machine itself has access to both\npieces of information necessary to authenticate. For example:\nconfiguration management will have the app IDs, but the machine itself\nwill detect its user ID based on some unique machine property such as a\nMAC address (or a hash of it with some salt).\n\nAn example, real world process for using this provider:\n\n 1. Create unique app IDs (UUIDs work well) and map them to policies.\n (Path: map\/app-id\/<app-id>)\n\n 2. Store the app IDs within configuration management systems.\n\n 3. An out-of-band process run by security operators map unique user IDs\n to these app IDs.

When a valid {app ID, user ID} tuple is given to the\n\"login\" path, then the user is authenticated with the configured app\nID policies.\n\nThe user ID can be any value (just like the app ID), however it is\ngenerally a value unique to a machine, such as a MAC address or instance ID,\nor a value hashed from these unique values.\n\nIt is possible to authorize multiple app IDs with each\nuser ID by writing them as comma-separated values to the map\/user-id\/<user-id>\npath.\n\nIt is also possible to renew the auth tokens with 'vault token-renew <token>' command.\nBefore the token is renewed, the validity of app ID, user ID and the associated\npolicies are checked again.\n`\n<commit_msg>Fix instantiation of salt funcs in app-id structs<commit_after>package appId\n\nimport (\n\t\"sync\"\n\n\t\"github.com\/hashicorp\/vault\/helper\/salt\"\n\t\"github.com\/hashicorp\/vault\/logical\"\n\t\"github.com\/hashicorp\/vault\/logical\/framework\"\n)\n\nfunc Factory(conf *logical.BackendConfig) (logical.Backend, error) {\n\tb, err := Backend(conf)\n\tif err != nil {\n\t\treturn nil, err\n\t}\n\treturn b.Setup(conf)\n}\n\nfunc Backend(conf *logical.BackendConfig) (*framework.Backend, error) {\n\tvar b backend\n\tb.MapAppId = &framework.PolicyMap{\n\t\tPathMap: framework.PathMap{\n\t\t\tName: \"app-id\",\n\t\t\tSchema: map[string]*framework.FieldSchema{\n\t\t\t\t\"display_name\": &framework.FieldSchema{\n\t\t\t\t\tType: framework.TypeString,\n\t\t\t\t\tDescription: \"A name to map to this app ID for logs.\",\n\t\t\t\t},\n\n\t\t\t\t\"value\": &framework.FieldSchema{\n\t\t\t\t\tType: framework.TypeString,\n\t\t\t\t\tDescription: \"Policies for the app ID.\",\n\t\t\t\t},\n\t\t\t},\n\t\t},\n\t\tDefaultKey: \"default\",\n\t}\n\n\tb.MapUserId = &framework.PathMap{\n\t\tName: \"user-id\",\n\t\tSchema: map[string]*framework.FieldSchema{\n\t\t\t\"cidr_block\": &framework.FieldSchema{\n\t\t\t\tType: framework.TypeString,\n\t\t\t\tDescription: \"If not blank, restricts auth by this CIDR block\",\n\t\t\t},\n\n\t\t\t\"value\": &framework.FieldSchema{\n\t\t\t\tType: framework.TypeString,\n\t\t\t\tDescription: \"App IDs that this user associates with.\",\n\t\t\t},\n\t\t},\n\t}\n\n\tb.Backend = &framework.Backend{\n\t\tHelp: backendHelp,\n\n\t\tPathsSpecial: &logical.Paths{\n\t\t\tUnauthenticated: []string{\n\t\t\t\t\"login\",\n\t\t\t\t\"login\/*\",\n\t\t\t},\n\t\t},\n\n\t\tPaths: framework.PathAppend([]*framework.Path{\n\t\t\tpathLogin(&b),\n\t\t\tpathLoginWithAppIDPath(&b),\n\t\t},\n\t\t\tb.MapAppId.Paths(),\n\t\t\tb.MapUserId.Paths(),\n\t\t),\n\n\t\tAuthRenew: b.pathLoginRenew,\n\n\t\tInvalidate: b.invalidate,\n\t}\n\n\tb.view = conf.StorageView\n\n\tb.MapAppId.SaltFunc = b.Salt\n\tb.MapUserId.SaltFunc = b.Salt\n\n\treturn b.Backend, nil\n}\n\ntype backend struct {\n\t*framework.Backend\n\n\tsalt *salt.Salt\n\tSaltMutex sync.RWMutex\n\tview logical.Storage\n\tMapAppId *framework.PolicyMap\n\tMapUserId *framework.PathMap\n}\n\nfunc (b *backend) Salt() (*salt.Salt, error) {\n\tb.SaltMutex.RLock()\n\tif b.salt != nil {\n\t\tdefer b.SaltMutex.RUnlock()\n\t\treturn b.salt, nil\n\t}\n\tb.SaltMutex.RUnlock()\n\tb.SaltMutex.Lock()\n\tdefer b.SaltMutex.Unlock()\n\tif b.salt != nil {\n\t\treturn b.salt, nil\n\t}\n\tsalt, err := salt.NewSalt(b.view, &salt.Config{\n\t\tHashFunc: salt.SHA1Hash,\n\t\tLocation: salt.DefaultLocation,\n\t})\n\tif err != nil {\n\t\treturn nil, err\n\t}\n\tb.salt = salt\n\treturn salt, nil\n}\n\nfunc (b *backend) invalidate(key string) {\n\tswitch key {\n\tcase salt.DefaultLocation:\n\t\tb.SaltMutex.Lock()\n\t\tdefer b.SaltMutex.Unlock()\n\t\tb.salt = nil\n\t}\n}\n\nconst backendHelp = `\nThe App ID credential provider is used to perform authentication from\nwithin applications or machine by pairing together two hard-to-guess\nunique pieces of information: a unique app ID, and a unique user ID.\n\nThe goal of this credential provider is to allow elastic users\n(dynamic machines, containers, etc.) to authenticate with Vault without\nhaving to store passwords outside of Vault.

allows for easy validation of passed in json.\nVal does not intend to be a robust solution but does seek to cover 95% of use cases.\nVal requires a structure to use pointers for validation. This may seem odd but if a pointer is\nnot used you will run into some strange issues since json.Decode() will pass an int type back \nset as 0 giving no way to tell if a 0 was actually passed in or not.

chrom-sweep.\n\/\/ broad design is covered in design.md in the irelate package directory.\n\/\/ In actual fact, there are a number of complexities; most of them relate to\n\/\/ maintaining intervals in sorted order (and keeping chunks in sorted order)\n\/\/ while allowing a good level of parallelism.\n\n\/\/ more detailed explanations are provided whenever a channel is initialized\n\/\/ as channels are our main means of keeping order.\n\/\/ For example\n\/\/ tochannels := make(chan chan chan []interfaces.Relatable, 2+nprocs\/2)\n\/\/ Seems to have excessive use of channels, but we actually do need this since\n\/\/ we have 2 levels of parallelization.\n\/\/ One level is by chunk of query intervals.\n\/\/ The next is by sub-chunk within the query chunks.\n\/\/ The 3rd chan is a place-holder so that the work() function, which calls\n\/\/ the user-defined fn() can be done concurrently (in a go routine).\n\n\/\/ The broad pattern used throughout is to send a channel (K) into another\n\/\/ channel (PARENT) to keep order and then send K into a worker goroutine\n\/\/ that sends intervals or []intervals into K.\n\n\/\/ I have done much tuning; the areas that affect performance are how the work()\n\/\/ is parallelized (see the code-block that calls work()). And how the query\n\/\/ chunks are determined. If the query chunks are too small (< 100 intervals),\n\/\/ we have a lot of overhead in tracking that chunk that only requires a little\n\/\/ computation. Unless the databases are very dense, then having the query chunks\n\/\/ quite large helps parallelization. This is an area of potential optimization,\n\/\/ though no obvious candidates have emerged.\n\nimport

Things like ruby, perl, gcc,\n python, php, go, node are preinstalled on your VM. You can start\n writing code right away without the need for new installs!\n\n Here are a few additional commonly asked questions. For more, head\n over to Koding University at http:\/\/learn.koding.com\n\n Some things to note:\n - The default web server root is linked to \/home\/{{ .Username }}\/Web\n so any file placed inside that directory will automatically\n be visible from this URL:\n http:\/\/{{.UserDomain}}\n\n - You can access this VM using any sub-domains that you may have\n set up. To learn more about sub-domains and how to set them up,\n please read this article on Koding University:\n http:\/\/learn.koding.com\/domains\n\n - To run a command as the ` + \"`\" + `root` + \"`\" + ` user, prefix any command with\n ` + \"`\" + `sudo <command>` + \"`\" + `. Remember, with great power, comes great\n responsibility! :)\n\n Common questions:\n ================\n # How can I find out which packages are installed on my VM?\n\n Run the command: ` + \"`\" + `dpkg --get-selections | grep -v deinstall` + \"`\" + ` to get\n a list of all installed packages. If a particular package is not\n installed, go ahead and install it using ` + \"`\" + `sudo apt-get install\n <package name>` + \"`\" + `. Using this command you can install databases like\n postgres, MySQL, Mongo, etc.\n\n # What is my sudo password?\n\n By default, you sudo password is blank. Most people like it that\n way but if you prefer, you can use the ` + \"`\" + `sudo passwd` + \"`\" + ` command and\n change the default (blank) password to something more secure.\n\n # How do I poweroff my VM?\n For our free acccounts, the VMs will power off automatically after\n 60 minutes of inactivity. However, if you wish to poweroff your\n VM manually, please use the VM settings panel to achieve that.\n\n\n For more questions and FAQ, head over to http:\/\/learn.koding.com\n or send us an email at support@koding.com\n path: \/home\/{{.Username}}\/README.md\n\n\n{{if .ShouldMigrate }}\n # User migration script (~\/migrate.sh)\n - content: |\n #!\/bin\/bash\n username={{.Username}}\n credentials=({{.Passwords}})\n vm_names=({{.VmNames}})\n vm_ids=({{.VmIds}})\n count=$((${#credentials[@]} - 1))\n counter=0\n clear\n if [ -f \/etc\/koding\/.kodingart.txt ]; then\n cat \/etc\/koding\/.kodingart.txt\n fi\n echo\n echo 'This migration assistant will help you move your VMs from the old Koding'\n echo 'environment to the new one.

(+ regexp-free parser)\n\/\/ - modifying files\n\/\/ - exporting files (+ metadata handling) (?)\n\/\/ - declare encoding (?)\n\/\/\npackage gcfg\n\nimport (\n\t\"bufio\"\n\t\"errors\"\n\t\"fmt\"\n\t\"io\"\n\t\"os\"\n\t\"reflect\"\n\t\"regexp\"\n\t\"strings\"\n)\n\nvar (\n\treCmnt = regexp.MustCompile(`^([^;#\"]*)[;#].*$`)\n\treCmntQ = regexp.MustCompile(`^([^;#\"]*\"[^\"]*\"[^;#\"]*)[;#].*$`)\n\treBlank = regexp.MustCompile(`^\\s*$`)\n\treSect = regexp.MustCompile(`^\\s*\\[\\s*([^\\s]*)\\s*\\]\\s*$`)\n\treVar = regexp.MustCompile(`^\\s*([^\"=\\s]+)\\s*=\\s*([^\"\\s]*)\\s*$`)\n\treVarQ = regexp.MustCompile(`^\\s*([^\"=\\s]+)\\s*=\\s*\"([^\"\\n\\\\]*)\"\\s*$`)\n\treVarDflt = regexp.MustCompile(`^\\s*\\b(.*)\\b\\s*$`)\n)\n\nconst (\n\t\/\/ Default value in case a value for a variable isn't provided.\n\tDefaultValue = \"true\"\n)\n\ntype Bool bool\n\nvar boolValues = map[string]interface{}{\n\t\"true\": true, \"yes\": true, \"on\": true, \"1\": true,\n\t\"false\": false, \"no\": false, \"off\": false, \"0\": false}\n\nfunc scan(state fmt.ScanState, values map[string]interface{}) (interface{}, error) {\n\tvar rd []rune\n\tvar r rune\n\tvar err error\n\tfor r, _, err = state.ReadRune(); err == nil; r, _, err = state.ReadRune() {\n\t\trd = append(rd, r)\n\t\tpart := false\n\t\tfor s, v := range values {\n\t\t\tif strings.EqualFold(string(rd), s) {\n\t\t\t\treturn v, err\n\t\t\t}\n\t\t\tif len(rd) < len(s) && strings.EqualFold(string(rd), s[:len(rd)]) {\n\t\t\t\tpart = true\n\t\t\t}\n\t\t}\n\t\tif part == false {\n\t\t\tstate.UnreadRune()\n\t\t\treturn nil, errors.New(\"unsupported value \" + string(rd))\n\t\t}\n\t}\n\treturn nil, err\n}\n\nfunc (b *Bool) Scan(state fmt.ScanState, verb rune) error {\n\tv, err := scan(state, boolValues)\n\tswitch bb := v.(type) {\n\tcase bool:\n\t\t*b = Bool(bb)\n\t\treturn err\n\t}\n\treturn err\n}\n\nfunc fieldFold(v reflect.Value, name string) reflect.Value {\n\tn := strings.Replace(name, \"-\", \"_\", -1)\n\treturn v.FieldByNameFunc(func(fieldName string) bool {\n\t\treturn strings.EqualFold(n, fieldName)\n\t})\n}\n\nfunc set(cfg interface{}, sect, name, value string) error {\n\tvDest := reflect.ValueOf(cfg).Elem()\n\tvSect := fieldFold(vDest, sect)\n\tvName := fieldFold(vSect, name)\n\tvAddr := vName.Addr().Interface()\n\tswitch v := vAddr.(type) {\n\tcase *string:\n\t\t*v = value\n\t\treturn nil\n\tcase *bool:\n\t\tvAddr = (*Bool)(v)\n\t}\n\t\/\/ attempt to read an extra rune to make sure the value is consumed \n\tvar r rune\n\tn, err := fmt.Sscanf(value, \"%v%c\", vAddr, &r)\n\tswitch {\n\tcase n < 1 || n == 1 && err != io.EOF:\n\t\treturn fmt.Errorf(\"failed to parse %q as %#v: parse error %v\", value,\n\t\t\tvName.Type(), err)\n\tcase n > 1:\n\t\treturn fmt.Errorf(\"failed to parse %q as %#v: extra characters\", value,\n\t\t\tvName.Type())\n\tcase n == 1 && err == io.EOF:\n\t\treturn nil\n\t}\n\tpanic(\"never reached\")\n}\n\n\/\/ Parse reads gcfg formatted data from reader and sets the values into the\n\/\/ corresponding fields in config.

You\n\t\/\/ should register an application for your bot, and set the ID before\n\t\/\/ creating a client to authenticate with Github.\n\tClientID string\n\t\/\/ ClientSecret is the secret key used to verify your registered\n\t\/\/ application. You should set the secret before creating a client to\n\t\/\/ authenticate with Github.\n\tClientSecret string\n\t\/\/ AccessToken is an OAuth token for the user you want your Github\n\t\/\/ interactions to be performed as. The bot will be commenting, opening\n\t\/\/ issues, etc as the user who owns this token. You should set an access\n\t\/\/ token before creating a client to authenticate with Github.\n\tAccessToken string\n\t\/\/ RedirectURL is the URL that Github should redirect to after a successful\n\t\/\/ web authentication. Since the bot does not perform web-based\n\t\/\/ authentication, this is likely a useless field. More information can be\n\t\/\/ found at https:\/\/developer.github.com\/v3\/oauth\/#redirect-urls.\n\tRedirectURL string\n\t\/\/ Scopes is the list of scopes that the OAuth token should be limited\n\t\/\/ to. Since the user that created the token can specify the scopes\n\t\/\/ available to the token when they create it, this field is probably also\n\t\/\/ useless.\n\tScopes []string\n\t\/\/ SharedClient is a variable for sharing a single OAuth client among\n\t\/\/ various handlers. For example, when a call to OpenIssue is made, you may\n\t\/\/ pass in a client of your own, if you want the issue hook to be handled\n\t\/\/ by a different Github user. If you do not pass in a client, then the\n\t\/\/ various hook methods will fall back to using this shared client.\n\tSharedClient *github.Client\n)\n\n\/\/ DefaultClient constructs a Github client based on the variables set in this\n\/\/ package (ClientID, ClientSecret, AccessToken). This can be used to quickly\n\/\/ create a client when you don't need any customization to the underlying\n\/\/ oauth client. It uses the NoContext context from the oauth2 package. See the\n\/\/ Token function for the Token it will use.\nfunc DefaultClient() *github.Client {\n\treturn github.NewClient(Config().Client(oauth2.NoContext, Token()))\n}\n\n\/\/ Config returns an oauth config object that can be used to generate a client\n\/\/ for communicating with Github.\nfunc Config() *oauth2.Config {\n\treturn &oauth2.Config{\n\t\tClientID: ClientID,\n\t\tClientSecret: ClientSecret,\n\t\tEndpoint: ghAuth.Endpoint,\n\t\tRedirectURL: RedirectURL,\n\t\tScopes: Scopes,\n\t}\n}\n\n\/\/ Token constructs a basic token, with the bare minimum amount of information\n\/\/ necessary to authenticate with Github. It uses the package-wide AccessToken,\n\/\/ and sets the token to never expire. \"TokenType\" and \"RefreshToken\" fields\n\/\/ are left blank.\nfunc Token() *oauth2.Token {\n\tvar noExpire time.Time \/\/ this sets noExpire to the zero Time value\n\treturn &oauth2.Token{\n\t\tAccessToken: AccessToken,\n\t\tTokenType: \"\", \/\/ uhhh\n\t\tRefreshToken: \"\",\n\t\tExpiry: noExpire,\n\t}\n}\n\n\/\/ OpenIssue registers a handler that will cause the bot to open a github issue\n\/\/ based on the event text.\n\/\/\n\/\/ The handler is registered as a \"Respond\", not a \"Listen\" (see the docs for\n\/\/ github.com\/ajm188\/slack for the difference). The pattern which will cause\n\/\/ the handler to fire has the form 'issue me \/\/ <owner>\/<repo> \"<title>\"\n\/\/ (\"<body>\" (\"<assignee>\")?)?'.\n\/\/\n\/\/ The function takes as arguments the bot to which it should register the\n\/\/ handler, and a reference to a client that can authenticate with Github. If\n\/\/ no client is provided, then OpenIssue will fall back to using the\n\/\/ package-wide SharedClient.\n\/\/\n\/\/ Users should note that an attempt to assign an issue to a Github user that\n\/\/ is not a \"contributor\" on the repository will result in a 422 returned by\n\/\/ the Github API. This will prevent the issue from being created.\n\/\/\n\/\/ When an issue has successfully been created, the bot will reply to the user\n\/\/ which triggered the handler with a link to the issue.\nfunc OpenIssue(bot *slack.Bot, client *github.Client) {\n\trepoRe := regexp.MustCompile(\"issue me ([^\/ ]+)\/([^\/ ]+)\")\n\targsRe := regexp.MustCompile(\"(\\\".*?[^\\\\\\\\]\\\")\")\n\tif client == nil {\n\t\tclient = SharedClient\n\t}\n\tissues := client.Issues\n\n\thandler := func(b *slack.Bot, event map[string]interface{}) (*slack.Message, slack.Status) {\n\t\ttext := event[\"text\"].(string)\n\t\towner, repo, err := extractOwnerAndRepo(text, repoRe)\n\t\tif err != nil {\n\t\t\treturn nil, slack.Continue\n\t\t}\n\t\tissueRequest, err := extractIssueArgs(text, argsRe)\n\t\tif err != nil {\n\t\t\treturn nil, slack.Continue\n\t\t}\n\t\tissue, _, err := issues.Create(owner, repo, issueRequest)\n\t\tuser := event[\"user\"].(string)\n\t\tchannel := event[\"channel\"].(string)\n\t\tif err != nil {\n\t\t\tmessage := fmt.Sprintf(\n\t\t\t\t\"I had some trouble opening an issue.

With the advent of services like\n\/\/ DropBox, Box, Google Drive and the like, this type of service is becoming more\n\/\/ commonplace EVH has some differentiating features that make it an especially\n\/\/ good tool for corporations and\/or home use.\n\/\/\n\/\/ EVH runs in two modes: server and client. Server hosts a web server interface for\n\/\/ uploading and downloading files. The Client is for uploading only and runs\n\/\/ in a terminal.

For instance, given the flag value:\n\n\tpath=\".:\/home\/bar:\/public\"\n\nfor a godoc started in \/home\/user\/godoc, absolute paths are mapped to package paths\nas follows:\n\n\t\/home\/user\/godoc\/x -> godoc\/x\n\t\/home\/bar\/x -> bar\/x\n\t\/public\/x -> public\/x\n\nPaths provided via -path may point to very large file systems that contain\nnon-Go files. Creating the subtree of directories with Go packages may take\na long amount of time. A file containing newline-separated directory paths\nmay be provided with the -filter flag; if it exists, only directories\non those paths are considered. If -filter_minutes is set, the filter_file is\nupdated regularly by walking the entire directory tree.\n\nWhen godoc runs as a web server and -index is set, a search index is maintained.\nThe index is created at startup and is automatically updated every time the\n-sync command terminates with exit status 0, indicating that files have changed.\n\nIf the sync exit status is 1, godoc assumes that it succeeded without errors\nbut that no files changed; the index is not updated in this case.\n\nIn all other cases, sync is assumed to have failed and godoc backs off running\nsync exponentially (up to 1 day). As soon as sync succeeds again (exit status 0\nor 1), the normal sync rhythm is re-established.\n\nThe index contains both identifier and full text search information (searchable\nvia regular expressions). The maximum number of full text search results shown\ncan be set with the -maxresults flag; if set to 0, no full text results are\nshown, and only an identifier index but no full text search index is created.\n\nThe presentation mode of web pages served by godoc can be controlled with the\n\"m\" URL parameter; it accepts a comma-separated list of flag names as value:\n\n\tall\tshow documentation for all declarations, not just the exported ones\n\tmethods\tshow all embedded methods, not just those of unexported anonymous fields\n\tsrc\tshow the original source code rather then the extracted documentation\n\ttext\tpresent the page in textual (command-line) form rather than HTML\n\tflat\tpresent flat (not indented) directory listings using full paths\n\nFor instance, http:\/\/golang.org\/pkg\/math\/big\/?m=all,text shows the documentation\nfor all (not just the exported) declarations of package big, in textual form (as\nit would appear when using godoc from the command line: \"godoc -src math\/big .*\").\n\nBy default, godoc serves files from the file system of the underlying OS.\nInstead, a .zip file may be provided via the -zip flag, which contains\nthe file system to serve. The file paths stored in the .zip file must use\nslash ('\/') as path separator; and they must be unrooted. $GOROOT (or -goroot)\nmust be set to the .zip file directory path containing the Go root directory.\nFor instance, for a .zip file created by the command:\n\n\tzip go.zip $HOME\/go\n\none may run godoc as follows:\n\n\tgodoc -http=:6060 -zip=go.zip -goroot=$HOME\/go\n\nSee \"Godoc: documenting Go code\" for how to write good comments for godoc:\nhttp:\/\/blog.golang.org\/2011\/03\/godoc-documenting-go-code.html\n*\/\npackage documentation\n<commit_msg>godoc: update documentation<commit_after>\/\/ Copyright 2009 The Go Authors.

The maximum number of full text search results shown\ncan be set with the -maxresults flag; if set to 0, no full text results are\nshown, and only an identifier index but no full text search index is created.\n\nThe presentation mode of web pages served by godoc can be controlled with the\n\"m\" URL parameter; it accepts a comma-separated list of flag names as value:\n\n\tall\tshow documentation for all declarations, not just the exported ones\n\tmethods\tshow all embedded methods, not just those of unexported anonymous fields\n\tsrc\tshow the original source code rather then the extracted documentation\n\ttext\tpresent the page in textual (command-line) form rather than HTML\n\tflat\tpresent flat (not indented) directory listings using full paths\n\nFor instance, http:\/\/golang.org\/pkg\/math\/big\/?m=all,text shows the documentation\nfor all (not just the exported) declarations of package big, in textual form (as\nit would appear when using godoc from the command line: \"godoc -src math\/big .*\").\n\nBy default, godoc serves files from the file system of the underlying OS.\nInstead, a .zip file may be provided via the -zip flag, which contains\nthe file system to serve. The file paths stored in the .zip file must use\nslash ('\/') as path separator; and they must be unrooted. $GOROOT (or -goroot)\nmust be set to the .zip file directory path containing the Go root directory.\nFor instance, for a .zip file created by the command:\n\n\tzip go.zip $HOME\/go\n\none may run godoc as follows:\n\n\tgodoc -http=:6060 -zip=go.zip -goroot=$HOME\/go\n\nSee \"Godoc: documenting Go code\" for how to write good comments for godoc:\nhttp:\/\/blog.golang.org\/2011\/03\/godoc-documenting-go-code.html\n\n*\/\npackage documentation\n<|endoftext|>"} {"text":"<commit_before>package main\n\nimport (\n\t\"fmt\"\n\t\"io\"\n\t\"log\"\n\t\"net\/http\"\n\t\"os\"\n\t\"path\"\n\t\"regexp\"\n\t\"strconv\"\n)\n\n\/\/ dataStoreSize limits the storage used by the data store.

driver.\n\/*\npgx provides lower level access to PostgreSQL than the standard database\/sql\nIt remains as similar to the database\/sql interface as possible while\nproviding better speed and access to PostgreSQL specific features. Import\ngithub.com\/jack\/pgx\/stdlib to use pgx as a database\/sql compatible driver.\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(\"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 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(\"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(\"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\nConnection Pool\n\nConnection pool usage is explicit and configurable. In pgx, a connection can\nbe created and managed directly, or a connection pool with a configurable\nmaximum connections can be used. Also, the connection pool offers an after\nconnect hook that allows every connection to be automatically setup before\nbeing made available in the connection pool. This is especially useful to\nensure all connections have the same prepared statements available or to\nchange any other connection settings.\n\nIt delegates Query, QueryRow, Exec, and Begin functions to an automatically\nchecked out and released connection so you can avoid manually acquiring and\nreleasing connections when you do not need that level of control.\n\n var name string\n var weight int64\n err := pool.QueryRow(\"select name, weight from widgets where id=$1\", 42).Scan(&name, &weight)\n if err != nil {\n return err\n }\n\nTransactions\n\nTransactions are started by calling Begin or BeginIso. The BeginIso variant\ncreates a transaction with a specified isolation level.\n\n tx, err := conn.Begin()\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()\n\n _, err = tx.Exec(\"insert into foo(id) values (1)\")\n if err != nil {\n return err\n }\n\n err = tx.Commit()\n if err != nil {\n return err\n }\n\nCopy Protocol\n\nUse CopyTo to efficiently insert multiple rows at a time using the PostgreSQL\ncopy protocol. CopyTo accepts a CopyToSource interface. If the data is already\nin a [][]interface{} use CopyToRows to wrap it in a CopyToSource interface. Or\nimplement CopyToSource 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.CopyTo(\n \"people\",\n []string{\"first_name\", \"last_name\", \"age\"},\n pgx.CopyToRows(rows),\n )\n\nCopyTo 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\nWaitForNotification function. It takes a maximum time to wait for a\nnotification.\n\n err := conn.Listen(\"channelname\")\n if err != nil {\n return nil\n }\n\n if notification, err := conn.WaitForNotification(time.Second); err != nil {\n \/\/ do something with notification\n }\n\nNull Mapping\n\npgx can map nulls in two ways. The first is Null* types that have a data field\nand a valid field. They work in a similar fashion to database\/sql. The second\nis to use a pointer to a pointer.\n\n var foo pgx.NullString\n var bar *string\n err := conn.QueryRow(\"select foo, bar from widgets where id=$1\", 42).Scan(&a, &b)\n if err != nil {\n return err\n }\n\nArray Mapping\n\npgx maps between int16, int32, int64, float32, float64, and string Go slices\nand the equivalent PostgreSQL array type. Go slices of native types do not\nsupport nulls, so if a PostgreSQL array that contains a null is read into a\nnative Go slice an error will occur.\n\nHstore Mapping\n\npgx includes an Hstore type and a NullHstore type. Hstore is simply a\nmap[string]string and is preferred when the hstore contains no nulls. NullHstore\nfollows the Null* pattern and supports null values.\n\nJSON and JSONB Mapping\n\npgx includes built-in support to marshal and unmarshal between Go types and\nthe PostgreSQL JSON and JSONB.\n\nInet and Cidr Mapping\n\npgx encodes from net.IPNet to and from inet and cidr PostgreSQL types. In\naddition, as a convenience pgx will encode from a net.IP; it will assume a \/32\nnetmask for IPv4 and a \/128 for IPv6.\n\nCustom Type Support\n\npgx includes support for the common data types like integers, floats, strings,\ndates, and times that have direct mappings between Go and SQL. Support can be\nadded for additional types like point, hstore, numeric, etc. that do not have\ndirect mappings in Go by the types implementing Scanner and Encoder.\n\nCustom types can support text or binary formats. Binary format can provide a\nlarge performance increase. The natural place for deciding the format for a\nvalue would be in Scanner as it is responsible for decoding the returned data.\nHowever, that is impossible as the query has already been sent by the time the\nScanner is invoked. The solution to this is the global DefaultTypeFormats. If a\ncustom type prefers binary format it should register it there.\n\n pgx.DefaultTypeFormats[\"point\"] = pgx.BinaryFormatCode\n\nNote that the type is referred to by name, not by OID. This is because custom\nPostgreSQL types like hstore will have different OIDs on different servers. When\npgx establishes a connection it queries the pg_type table for all types. It then\nmatches the names in DefaultTypeFormats with the returned OIDs and stores it in\nConn.PgTypes.\n\nSee example_custom_type_test.go for an example of a custom type for the\nPostgreSQL point type.\n\npgx also includes support for custom types implementing the database\/sql.Scanner\nand database\/sql\/driver.Valuer interfaces.\n\nRaw Bytes Mapping\n\n[]byte passed as arguments to Query, QueryRow, and Exec are passed unmodified\nto PostgreSQL. In like manner, a *[]byte passed to Scan will be filled with\nthe raw bytes returned by PostgreSQL. This can be especially useful for reading\nvarchar, text, json, and jsonb values directly into a []byte and avoiding the\ntype conversion from string.\n\nTLS\n\nThe pgx ConnConfig struct has a TLSConfig field. If this field is\nnil, then TLS will be disabled. If it is present, then it will be used to\nconfigure the TLS connection. This allows total configuration of the TLS\nconnection.\n\nLogging\n\npgx defines a simple logger interface. Connections optionally accept a logger\nthat satisfies this interface. The log15 package\n(http:\/\/gopkg.in\/inconshreveable\/log15.v2) satisfies this interface and it is\nsimple to define adapters for other loggers. Set LogLevel to control logging\nverbosity.\n*\/\npackage pgx\n<commit_msg>Add mapping information for core types.<commit_after>\/\/ Package pgx is a PostgreSQL database driver.\n\/*\npgx provides lower level access to PostgreSQL than the standard database\/sql\nIt remains as similar to the database\/sql interface as possible while\nproviding better speed and access to PostgreSQL specific features. Import\ngithub.com\/jack\/pgx\/stdlib to use pgx as a database\/sql compatible driver.\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(\"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 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(\"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(\"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\nConnection Pool\n\nConnection pool usage is explicit and configurable. In pgx, a connection can\nbe created and managed directly, or a connection pool with a configurable\nmaximum connections can be used. Also, the connection pool offers an after\nconnect hook that allows every connection to be automatically setup before\nbeing made available in the connection pool. This is especially useful to\nensure all connections have the same prepared statements available or to\nchange any other connection settings.\n\nIt delegates Query, QueryRow, Exec, and Begin functions to an automatically\nchecked out and released connection so you can avoid manually acquiring and\nreleasing connections when you do not need that level of control.\n\n var name string\n var weight int64\n err := pool.QueryRow(\"select name, weight from widgets where id=$1\", 42).Scan(&name, &weight)\n if err != nil {\n return err\n }\n\nBase Type Mapping\n\npgx maps between all common base types directly between Go and PostgreSQL. In\nparticular:\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 Null* types that have a data field\nand a valid field. They work in a similar fashion to database\/sql. The second\nis to use a pointer to a pointer.\n\n var foo pgx.NullString\n var bar *string\n err := conn.QueryRow(\"select foo, bar from widgets where id=$1\", 42).Scan(&a, &b)\n if err != nil {\n return err\n }\n\nArray Mapping\n\npgx maps between int16, int32, int64, float32, float64, and string Go slices\nand the equivalent PostgreSQL array type. Go slices of native types do not\nsupport nulls, so if a PostgreSQL array that contains a null is read into a\nnative Go slice an error will occur.\n\nHstore Mapping\n\npgx includes an Hstore type and a NullHstore type. Hstore is simply a\nmap[string]string and is preferred when the hstore contains no nulls. NullHstore\nfollows the Null* pattern and supports null values.\n\nJSON and JSONB Mapping\n\npgx includes built-in support to marshal and unmarshal between Go types and\nthe PostgreSQL JSON and JSONB.\n\nInet and Cidr Mapping\n\npgx encodes from net.IPNet to and from inet and cidr PostgreSQL types. In\naddition, as a convenience pgx will encode from a net.IP; it will assume a \/32\nnetmask for IPv4 and a \/128 for IPv6.\n\nCustom Type Support\n\npgx includes support for the common data types like integers, floats, strings,\ndates, and times that have direct mappings between Go and SQL. Support can be\nadded for additional types like point, hstore, numeric, etc. that do not have\ndirect mappings in Go by the types implementing Scanner and Encoder.\n\nCustom types can support text or binary formats. Binary format can provide a\nlarge performance increase. The natural place for deciding the format for a\nvalue would be in Scanner as it is responsible for decoding the returned data.\nHowever, that is impossible as the query has already been sent by the time the\nScanner is invoked. The solution to this is the global DefaultTypeFormats. If a\ncustom type prefers binary format it should register it there.\n\n pgx.DefaultTypeFormats[\"point\"] = pgx.BinaryFormatCode\n\nNote that the type is referred to by name, not by OID. This is because custom\nPostgreSQL types like hstore will have different OIDs on different servers. When\npgx establishes a connection it queries the pg_type table for all types. It then\nmatches the names in DefaultTypeFormats with the returned OIDs and stores it in\nConn.PgTypes.\n\nSee example_custom_type_test.go for an example of a custom type for the\nPostgreSQL point type.\n\npgx also includes support for custom types implementing the database\/sql.Scanner\nand database\/sql\/driver.Valuer interfaces.\n\nRaw Bytes Mapping\n\n[]byte passed as arguments to Query, QueryRow, and Exec are passed unmodified\nto PostgreSQL. In like manner, a *[]byte passed to Scan will be filled with\nthe raw bytes returned by PostgreSQL. This can be especially useful for reading\nvarchar, text, json, and jsonb values directly into a []byte and avoiding the\ntype conversion from string.\n\nTransactions\n\nTransactions are started by calling Begin or BeginIso. The BeginIso variant\ncreates a transaction with a specified isolation level.\n\n tx, err := conn.Begin()\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()\n\n _, err = tx.Exec(\"insert into foo(id) values (1)\")\n if err != nil {\n return err\n }\n\n err = tx.Commit()\n if err != nil {\n return err\n }\n\nCopy Protocol\n\nUse CopyTo to efficiently insert multiple rows at a time using the PostgreSQL\ncopy protocol. CopyTo accepts a CopyToSource interface. If the data is already\nin a [][]interface{} use CopyToRows to wrap it in a CopyToSource interface. Or\nimplement CopyToSource 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.CopyTo(\n \"people\",\n []string{\"first_name\", \"last_name\", \"age\"},\n pgx.CopyToRows(rows),\n )\n\nCopyTo 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\nWaitForNotification function. It takes a maximum time to wait for a\nnotification.\n\n err := conn.Listen(\"channelname\")\n if err != nil {\n return nil\n }\n\n if notification, err := conn.WaitForNotification(time.Second); err != nil {\n \/\/ do something with notification\n }\n\nTLS\n\nThe pgx ConnConfig struct has a TLSConfig field. If this field is\nnil, then TLS will be disabled. If it is present, then it will be used to\nconfigure the TLS connection. This allows total configuration of the TLS\nconnection.\n\nLogging\n\npgx defines a simple logger interface. Connections optionally accept a logger\nthat satisfies this interface. The log15 package\n(http:\/\/gopkg.in\/inconshreveable\/log15.v2) satisfies this interface and it is\nsimple to define adapters for other loggers.

To check the available platforms\/charms, check this\nURL: https:\/\/github.com\/timeredbull\/charms\/tree\/master\/centos.\n\nIn order to create an app, you need to be member of at least one team. All\nteams that you are member (see \"tsuru team-list\") will be able to access the\napp.\n\n\nRemove an app\n\nUsage:\n\n\t% tsuru app-remove <appname>\n\napp-remove removes an app. If the app is binded to any service instance, it\nwill be unbinded before be removed (see \"tsuru unbind\"). You need to be a\nmember of a team that has access to the app to be able to remove it (you are\nable to remove any app that you see in \"tsuru app-list\").\n\n\nList apps that the user has access to\n\nUsage:\n\n\t% tsuru app-list\n\napp-list will list all apps that you have access to. App access is controlled\nby teams. If your team has access to an app, then you have access to it.\n\n\nAllow a team to access an app\n\nUsage:\n\n\t% tsuru app-grant <appname> <teamname>\n\napp-grant will allow a team to access an app. You need to be a member of a team\nthat has access to the app to allow another team to access it.\n\n\nRevoke from a team access to an app\n\nUsage:\n\n\t% tsuru app-revoke <appname> <teamname>\n\napp-revoke will revoke the permission to access an app from a team. You need to\nhave access to the app to revoke access from a team.\n\nAn app cannot be orphaned, so it will always have at least one authorized team.\n\n\nSee app's logs\n\nUsage:\n\n\t% tsuru log <appname>\n\nLog will show log entries for an app. These logs are not related to the code of\nthe app itself, but to actions of the app in tsuru server (deployments,\nrestarts, etc.).\n\n\nRun an arbitrary command in the app machine\n\nUsage:\n\n\t% tsuru run <appname> <command> [commandarg1] [commandarg2] ... [commandargn]\n\nRun will run an arbitrary command in the app machine. Base directory for all\ncommands is the root of the app. For example, in a Django app, \"tsuru run\" may\nshow the following output:\n\n\n\t% tsuru run polls ls -l\n\tapp.conf\n\tbrogui\n\tdeploy\n\tfoo\n\t__init__.py\n\t__init__.pyc\n\tmain.go\n\tmanage.py\n\tsettings.py\n\tsettings.pyc\n\ttemplates\n\turls.py\n\turls.pyc\n\n\nRestart the app's application server\n\nUsage:\n\n\t% tsuru restart <appname>\n\nRestart will call the restart hook from the app platform (the \"restart\" hook\nfrom the Juju charm).\n*\/\npackage documentation\n<|endoftext|>"} {"text":"<commit_before>\/*\nPackage gorocksdb provides the ability to create and access RocksDB databases.\n\ngorocksdb.OpenDb opens and creates databases.\n\n\topts := gorocksdb.NewDefaultOptions()\n\topts.SetBlockCache(gorocksdb.NewLRUCache(3<<30))\n\topts.SetCreateIfMissing(true)\n\tdb, err := gorocksdb.OpenDb(opts, \"\/path\/to\/db\")\n\nThe DB struct returned by OpenDb provides DB.Get, DB.Put, DB.Merge and DB.Delete to modify\nand query the database.\n\n\tro := gorocksdb.NewDefaultReadOptions()\n\two := gorocksdb.NewDefaultWriteOptions()\n\t\/\/ if ro and wo are not used again, be sure to Close them.\n\terr = db.Put(wo, []byte(\"foo\"), []byte(\"bar\"))\n\t...\n\tvalue, err := db.Get(ro, []byte(\"foo\"))\n\tdefer value.Free()\n\t...\n\terr = db.Delete(wo, []byte(\"foo\"))\n\nFor bulk reads, use an Iterator.

Only one type of the arguments may be specified: filenames,\n\t\tresources and names, or resources and label selector.\n\n\t\tSome resources, such as pods, support graceful deletion. These resources define a default period\n\t\tbefore they are forcibly terminated (the grace period) but you may override that value with\n\t\tthe --grace-period flag, or pass --now to set a grace-period of 1. Because these resources often\n\t\trepresent entities in the cluster, deletion may not be acknowledged immediately. If the node\n\t\thosting a pod is down or cannot reach the API server, termination may take significantly longer\n\t\tthan the grace period. To force delete a resource, you must pass a grace period of 0 and specify\n\t\tthe --force flag.\n\n\t\tIMPORTANT: Force deleting pods does not wait for confirmation that the pod's processes have been\n\t\tterminated, which can leave those processes running until the node detects the deletion and\n\t\tcompletes graceful deletion. If your processes use shared storage or talk to a remote API and\n\t\tdepend on the name of the pod to identify themselves, force deleting those pods may result in\n\t\tmultiple processes running on different machines using the same identification which may lead\n\t\tto data corruption or inconsistency. Only force delete pods when you are sure the pod is\n\t\tterminated, or if your application can tolerate multiple copies of the same pod running at once.\n\t\tAlso, if you force delete pods the scheduler may place new pods on those nodes before the node\n\t\thas released those resources and causing those pods to be evicted immediately.\n\n\t\tNote that the delete command does NOT do resource version checks, so if someone submits an\n\t\tupdate to a resource right when you submit a delete, their update will be lost along with the\n\t\trest of the resource.`))\n\n\tdelete_example = templates.Examples(i18n.T(`\n\t\t# Delete a pod using the type and name specified in pod.json.\n\t\tkubectl delete -f .\/pod.json\n\n\t\t# Delete a pod based on the type and name in the JSON passed into stdin.\n\t\tcat pod.json | kubectl delete -f -\n\n\t\t# Delete pods and services with same names \"baz\" and \"foo\"\n\t\tkubectl delete pod,service baz foo\n\n\t\t# Delete pods and services with label name=myLabel.\n\t\tkubectl delete pods,services -l name=myLabel\n\n\t\t# Delete a pod with minimal delay\n\t\tkubectl delete pod foo --now\n\n\t\t# Force delete a pod on a dead node\n\t\tkubectl delete pod foo --grace-period=0 --force\n\n\t\t# Delete all pods\n\t\tkubectl delete pods --all`))\n)\n\ntype DeleteOptions struct {\n\tresource.FilenameOptions\n\n\tLabelSelector string\n\tFieldSelector string\n\tDeleteAll bool\n\tIgnoreNotFound bool\n\tCascade bool\n\tDeleteNow bool\n\tForceDeletion bool\n\tWaitForDeletion bool\n\n\tGracePeriod int\n\tTimeout time.Duration\n\n\tOutput string\n\n\tDynamicClient dynamic.Interface\n\tMapper meta.RESTMapper\n\tResult *resource.Result\n\n\tgenericclioptions.IOStreams\n}\n\nfunc NewCmdDelete(f cmdutil.Factory, streams genericclioptions.IOStreams) *cobra.Command {\n\tdeleteFlags := NewDeleteCommandFlags(\"containing the resource to delete.\")\n\n\tcmd := &cobra.Command{\n\t\tUse: \"delete ([-f FILENAME] | TYPE [(NAME | -l label | --all)])\",\n\t\tDisableFlagsInUseLine: true,\n\t\tShort: i18n.T(\"Delete resources by filenames, stdin, resources and names, or by resources and label selector\"),\n\t\tLong: delete_long,\n\t\tExample: delete_example,\n\t\tRun: func(cmd *cobra.Command, args []string) {\n\t\t\to := deleteFlags.ToOptions(nil, streams)\n\t\t\tcmdutil.CheckErr(o.Complete(f, args, cmd))\n\t\t\tcmdutil.CheckErr(o.Validate(cmd))\n\t\t\tcmdutil.CheckErr(o.RunDelete())\n\t\t},\n\t\tSuggestFor: []string{\"rm\"},\n\t}\n\n\tdeleteFlags.AddFlags(cmd)\n\n\tcmdutil.AddIncludeUninitializedFlag(cmd)\n\treturn cmd\n}\n\nfunc (o *DeleteOptions) Complete(f cmdutil.Factory, args []string, cmd *cobra.Command) error {\n\tcmdNamespace, enforceNamespace, err := f.ToRawKubeConfigLoader().Namespace()\n\tif err != nil {\n\t\treturn err\n\t}\n\n\tif o.DeleteAll || len(o.LabelSelector) > 0 || len(o.FieldSelector) > 0 {\n\t\tif f := cmd.Flags().Lookup(\"ignore-not-found\"); f != nil && !f.Changed {\n\t\t\t\/\/ If the user didn't explicitly set the option, default to ignoring NotFound errors when used with --all, -l, or --field-selector\n\t\t\to.IgnoreNotFound = true\n\t\t}\n\t}\n\tif o.DeleteNow {\n\t\tif o.GracePeriod != -1 {\n\t\t\treturn fmt.Errorf(\"--now and --grace-period cannot be specified together\")\n\t\t}\n\t\to.GracePeriod = 1\n\t}\n\tif o.GracePeriod == 0 && !o.ForceDeletion {\n\t\t\/\/ To preserve backwards compatibility, but prevent accidental data loss, we convert --grace-period=0\n\t\t\/\/ into --grace-period=1.

Only one type of the arguments may be specified: filenames,\n\t\tresources and names, or resources and label selector.\n\n\t\tSome resources, such as pods, support graceful deletion. These resources define a default period\n\t\tbefore they are forcibly terminated (the grace period) but you may override that value with\n\t\tthe --grace-period flag, or pass --now to set a grace-period of 1. Because these resources often\n\t\trepresent entities in the cluster, deletion may not be acknowledged immediately. If the node\n\t\thosting a pod is down or cannot reach the API server, termination may take significantly longer\n\t\tthan the grace period. To force delete a resource, you must pass a grace period of 0 and specify\n\t\tthe --force flag.\n\n\t\tIMPORTANT: Force deleting pods does not wait for confirmation that the pod's processes have been\n\t\tterminated, which can leave those processes running until the node detects the deletion and\n\t\tcompletes graceful deletion. If your processes use shared storage or talk to a remote API and\n\t\tdepend on the name of the pod to identify themselves, force deleting those pods may result in\n\t\tmultiple processes running on different machines using the same identification which may lead\n\t\tto data corruption or inconsistency. Only force delete pods when you are sure the pod is\n\t\tterminated, or if your application can tolerate multiple copies of the same pod running at once.\n\t\tAlso, if you force delete pods the scheduler may place new pods on those nodes before the node\n\t\thas released those resources and causing those pods to be evicted immediately.\n\n\t\tNote that the delete command does NOT do resource version checks, so if someone submits an\n\t\tupdate to a resource right when you submit a delete, their update will be lost along with the\n\t\trest of the resource.`))\n\n\tdelete_example = templates.Examples(i18n.T(`\n\t\t# Delete a pod using the type and name specified in pod.json.\n\t\tkubectl delete -f .\/pod.json\n\n\t\t# Delete a pod based on the type and name in the JSON passed into stdin.\n\t\tcat pod.json | kubectl delete -f -\n\n\t\t# Delete pods and services with same names \"baz\" and \"foo\"\n\t\tkubectl delete pod,service baz foo\n\n\t\t# Delete pods and services with label name=myLabel.\n\t\tkubectl delete pods,services -l name=myLabel\n\n\t\t# Delete a pod with minimal delay\n\t\tkubectl delete pod foo --now\n\n\t\t# Force delete a pod on a dead node\n\t\tkubectl delete pod foo --grace-period=0 --force\n\n\t\t# Delete all pods\n\t\tkubectl delete pods --all`))\n)\n\ntype DeleteOptions struct {\n\tresource.FilenameOptions\n\n\tLabelSelector string\n\tFieldSelector string\n\tDeleteAll bool\n\tIgnoreNotFound bool\n\tCascade bool\n\tDeleteNow bool\n\tForceDeletion bool\n\tWaitForDeletion bool\n\n\tGracePeriod int\n\tTimeout time.Duration\n\n\tOutput string\n\n\tDynamicClient dynamic.Interface\n\tMapper meta.RESTMapper\n\tResult *resource.Result\n\n\tgenericclioptions.IOStreams\n}\n\nfunc NewCmdDelete(f cmdutil.Factory, streams genericclioptions.IOStreams) *cobra.Command {\n\tdeleteFlags := NewDeleteCommandFlags(\"containing the resource to delete.\")\n\n\tcmd := &cobra.Command{\n\t\tUse: \"delete ([-f FILENAME] | TYPE [(NAME | -l label | --all)])\",\n\t\tDisableFlagsInUseLine: true,\n\t\tShort: i18n.T(\"Delete resources by filenames, stdin, resources and names, or by resources and label selector\"),\n\t\tLong: delete_long,\n\t\tExample: delete_example,\n\t\tRun: func(cmd *cobra.Command, args []string) {\n\t\t\to := deleteFlags.ToOptions(nil, streams)\n\t\t\tcmdutil.CheckErr(o.Complete(f, args, cmd))\n\t\t\tcmdutil.CheckErr(o.Validate(cmd))\n\t\t\tcmdutil.CheckErr(o.RunDelete())\n\t\t},\n\t\tSuggestFor: []string{\"rm\"},\n\t}\n\n\tdeleteFlags.AddFlags(cmd)\n\n\tcmdutil.AddIncludeUninitializedFlag(cmd)\n\treturn cmd\n}\n\nfunc (o *DeleteOptions) Complete(f cmdutil.Factory, args []string, cmd *cobra.Command) error {\n\tcmdNamespace, enforceNamespace, err := f.ToRawKubeConfigLoader().Namespace()\n\tif err != nil {\n\t\treturn err\n\t}\n\n\tif o.DeleteAll || len(o.LabelSelector) > 0 || len(o.FieldSelector) > 0 {\n\t\tif f := cmd.Flags().Lookup(\"ignore-not-found\"); f != nil && !f.Changed {\n\t\t\t\/\/ If the user didn't explicitly set the option, default to ignoring NotFound errors when used with --all, -l, or --field-selector\n\t\t\to.IgnoreNotFound = true\n\t\t}\n\t}\n\tif o.DeleteNow {\n\t\tif o.GracePeriod != -1 {\n\t\t\treturn fmt.Errorf(\"--now and --grace-period cannot be specified together\")\n\t\t}\n\t\to.GracePeriod = 1\n\t}\n\tif o.GracePeriod == 0 && !o.ForceDeletion {\n\t\t\/\/ To preserve backwards compatibility, but prevent accidental data loss, we convert --grace-period=0\n\t\t\/\/ into --grace-period=1.

If successful, it will create a \ncorresponding process element and attach it to the anchor. <code>MakeProc<\/code> returns the \nnewly created process element (of type <code>Proc<\/code>) as well as an \n<a href=\"api.html#errors\">application error<\/a> (of type <code>error<\/code>), or it panics if a \n<a href=\"api.html#errors\">system error<\/a> occurs.\n\n<p>An application error can occur in one of two cases. Either the anchor already has another element\nattached to it, or the process execution was rejected by the host OS (due to a missing binary or\n\tinsufficient permissions, for example). \n\n<p><code>MakeProc<\/code> never blocks.\n\n<p>The command parameter, of type <code>Cmd<\/code>, specifies the standard POSIX-level execution\nparameters and an additional parameter called <code>Scrub<\/code>:\n<pre>\ntype Cmd struct {\n\tEnv []string\n\tDir string\n\tPath string\n\tArgs []string\n\tScrub bool\n}\n<\/pre>\n\n<p>If <code>Scrub<\/code> is set, the process element will automatically be detached from the anchor\nand discarded, as soon as the underlying OS process exits. If <code>Scrub<\/code> is not set,\nthe process element will remain attached to the anchor even after the underlying OS process dies.\nThe latter regime is useful when one wants to start a job and return at a later time to check if\nthe job has already completed and what was its exit status. Furthermore, removing process elements\nexplicitly (rather than automatically) is a way of explicit accounting on the user's side. Thus\nthis regime is particularly well suited for applications that control circuit processes \nprogrammatically (as opposed to manually).\n\n<p>Regardless of the setting of the <code>Scrub<\/code> parameter, the user can\nuse the <code>Scrub<\/code> method to discard the process element at any point:\n<pre>\n\tScrub()\n<\/pre>\n\n<p>A call to <code>Scrub<\/code> will detach the process element from its anchor\nand discard it, thereby freeing the anchor to attach other elements. \nIf the underlying OS process is still running, ‘scrubbing’ will not\nterminate the process. (If OS process termination is desired, the user\nmust explicitly send a kill signal to the process, using a <code>Signal<\/code>\nwhich is described later.)\n\n<h4>Example<\/h4>\n<p>For instance, the following code executes the GNU list command:\n<pre>\n\tproc, err := a.MakeProc(\n\t\tcli.Cmd{\n\t\t\tEnv: []string{\"TERM=xterm\"},\n\t\t\tDir: \"\/\",\n\t\t\tPath: \"\/bin\/ls\",\n\t\t\tArgs: []string{\"-l\", \"\/\"},\n\t\t\tScrub: true,\n\t\t},\n\t)\n<\/pre>\n\n<p>The following picture tries to illustrate the relationship between the\nprocess element and the underlying OS process itself.\n\n{{.FigMkProc}}\n\n<h3>Controlling the standard file descriptors of a process<\/h3>\n\n<p>After its invocation, <code>MakeProc<\/code> returns immediately,\nwhile the underlying OS process is executing on the host machine.\n\n<p>After a successful execution the user is obligated, by the POSIX \nstandard, to take care of the standard input, output and error\nstreams of the underlying process. (For instance, if the standard\n\tinput is not written to or closed, or if the output is not\n\tread from, some programs will pause in waiting.)\n\n<p>The standard streams of the executed process can be retrieved\nwith the following methods of the process element:\n<pre>\n\tStdin() io.WriteCloser\n\tStdout() io.ReadCloser\n\tStderr() io.ReadCloser\n<\/pre>\n\n<p>It is allowed to close the standard output and error at any point\ninto the stream. This will result in discarding all remaining data\nin the stream, without blocking the underlying process.\n\n<p>Eventually, the user is responsible for closing all standard streams\notherwise the underlying process will block and not exit.\n\n<h3>Sending signals and killing processes<\/h3>\n\n<p>You can send a POSIX signal to the underlying process\nat any point (asynchronously) using:\n<pre>\n\tSignal(sig string) error\n<\/pre>\n\n<p>The <code>sig<\/code> string must be one of the following recognized\nsignal names:\n\t<code>ABRT<\/code>,\n\t<code>ALRM<\/code>,\n\t<code>BUS<\/code>,\n\t<code>CHLD<\/code>,\n\t<code>CONT<\/code>,\n\t<code>FPE<\/code>,\n\t<code>HUP<\/code>,\n\t<code>ILL<\/code>,\n\t<code>INT<\/code>,\n\t<code>IO<\/code>,\n\t<code>IOT<\/code>,\n\t<code>KILL<\/code>,\n\t<code>PIPE<\/code>,\n\t<code>PROF<\/code>,\n\t<code>QUIT<\/code>,\n\t<code>SEGV<\/code>,\n\t<code>STOP<\/code>,\n\t<code>SYS<\/code>,\n\t<code>TERM<\/code>,\n\t<code>TRAP<\/code>,\n\t<code>TSTP<\/code>,\n\t<code>TTIN<\/code>,\n\t<code>TTOU<\/code>,\n\t<code>URG<\/code>,\n\t<code>USR1<\/code>,\n\t<code>USR2<\/code>,\n\t<code>VTALRM<\/code>,\n\t<code>WINCH<\/code>,\n\t<code>XCPU<\/code>,\n\t<code>XFSZ<\/code>.\n\n<h3>Querying the status of a process asynchronously<\/h3>\n\n<p>You can query the status of a process asynchronously, using:\n<pre>\n\tPeek() ProcStat\n<\/pre>\n\n<p>The returned structure includes the command that started the process, a phase string describing the state of the\nprocess and, in the event that the process has exited, an exit error value or <code>nil<\/code> on successful exit.\n<pre>\n\ttype ProcStat struct {\n\t\tCmd Cmd\n\t\tExit error\n\t\tPhase string\n\t}\n<\/pre>\n\n<p>The phase string takes on one of the following values:\n<code>running<\/code>, \n<code>exited<\/code>,\n<code>stopped<\/code>, \n<code>signaled<\/code>,\n <code>continued<\/code>.\n\n\n<h3>Waiting until a process exits<\/h3>\n\n<p>Finally, you can call <code>Wait<\/code> asynchronously to block until the process ends:\n<pre>\n\tWait() (ProcStat, error)\n<\/pre>\n\n<p>If you call <code>Wait<\/code> before the process has exited, the invocation will block\nuntil exit occurs.

Another\n\t\/\/ European CA marked its signature keys as not being valid for\n\t\/\/ signatures. A different CA marked its own trusted root certificate\n\t\/\/ as being invalid for certificate signing. Another national CA\n\t\/\/ distributed a certificate to be used to encrypt data for the\n\t\/\/ country’s tax authority that was marked as only being usable for\n\t\/\/ digital signatures but not for encryption. Yet another CA reversed\n\t\/\/ the order of the bit flags in the keyUsage due to confusion over\n\t\/\/ encoding endianness, essentially setting a random keyUsage in\n\t\/\/ certificates that it issued. Another CA created a self-invalidating\n\t\/\/ certificate by adding a certificate policy statement stipulating\n\t\/\/ that the certificate had to be used strictly as specified in the\n\t\/\/ keyUsage, and a keyUsage containing a flag indicating that the RSA\n\t\/\/ encryption key could only be used for Diffie-Hellman key agreement.\n\n\tif certType == intermediateCertificate && (!c.BasicConstraintsValid || !c.IsCA) {\n\t\treturn CertificateInvalidError{c, NotAuthorizedToSign}\n\t}\n\n\tif c.BasicConstraintsValid && c.MaxPathLen >= 0 {\n\t\tnumIntermediates := len(currentChain) - 1\n\t\tif numIntermediates > c.MaxPathLen {\n\t\t\treturn CertificateInvalidError{c, TooManyIntermediates}\n\t\t}\n\t}\n\n\treturn nil\n}\n\n\/\/ Verify attempts to verify c by building one or more chains from c to a\n\/\/ certificate in opts.Roots, using certificates in opts.Intermediates if\n\/\/ needed.

Another\n\t\/\/ European CA marked its signature keys as not being valid for\n\t\/\/ signatures. A different CA marked its own trusted root certificate\n\t\/\/ as being invalid for certificate signing. Another national CA\n\t\/\/ distributed a certificate to be used to encrypt data for the\n\t\/\/ country’s tax authority that was marked as only being usable for\n\t\/\/ digital signatures but not for encryption. Yet another CA reversed\n\t\/\/ the order of the bit flags in the keyUsage due to confusion over\n\t\/\/ encoding endianness, essentially setting a random keyUsage in\n\t\/\/ certificates that it issued. Another CA created a self-invalidating\n\t\/\/ certificate by adding a certificate policy statement stipulating\n\t\/\/ that the certificate had to be used strictly as specified in the\n\t\/\/ keyUsage, and a keyUsage containing a flag indicating that the RSA\n\t\/\/ encryption key could only be used for Diffie-Hellman key agreement.\n\n\tif certType == intermediateCertificate && (!c.BasicConstraintsValid || !c.IsCA) {\n\t\treturn CertificateInvalidError{c, NotAuthorizedToSign}\n\t}\n\n\tif c.BasicConstraintsValid && c.MaxPathLen >= 0 {\n\t\tnumIntermediates := len(currentChain) - 1\n\t\tif numIntermediates > c.MaxPathLen {\n\t\t\treturn CertificateInvalidError{c, TooManyIntermediates}\n\t\t}\n\t}\n\n\treturn nil\n}\n\n\/\/ Verify attempts to verify c by building one or more chains from c to a\n\/\/ certificate in opts.Roots, using certificates in opts.Intermediates if\n\/\/ needed.

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\/\/

The result of unpickling\nthe above is map[interface{}]interface{} with a key \"a\" that contains\na reference to itself.\n\nAttempting to unpack the result of the above python code into a structure\nwith UnpackInto would either fail or recurse forever.\n\nProtocol Performance\n\nIf the version of Python you are using supports protocol version 1 or 2,\nyou should always specify that protocol version. By default the \"pickle\"\nand \"cPickle\" modules in Python write using protocol 0. Protocol 0\nrequires much more space to represent the same values and is much\nslower to parse.\n\nUnsupported Opcodes\n\nThe pickle format is incredibly flexible and as a result has some\nfeatures that are impractical or unimportant when implementing a reader in\nanother language.\n\nEach set of opcodes is listed below by protocol version with the impact.\n\nProtocol 0\n\n\tGLOBAL\n\nThis opcode is equivalent to calling \"import foo; foo.bar\" in python. It is\ngenerated whenever an object instance, class definition, or method definition\nis serialized. As long as the pickled data does not contain an instance\nof a python class or a reference to a python callable this opcode is not\nemitted by the \"pickle\" module.\n\nA few examples of what will definitely cause this opcode to be emitted\n\n\tpickle.dumps(range) #Pickling the range function\n\tpickle.dumps(Exception()) #Pickling an instance of a python class\n\nThis opcode will be partially supported in a future revision to this package\nthat allows the unpickling of instances of Python classes.\n\n\tREDUCE\n\tBUILD\n\tINST\n\nThese opcodes are used in recreating pickled python objects. That is currently\nnot supported by this package.\n\nThese opcodes will be supported in a future revision to this package\nthat allows the unpickling of instances of Python classes.\n\n\tPERSID\n\nThis opcode is used to reference concrete definitions of objects between\na pickler and an unpickler by an ID number. The pickle protocol doesn't define\nwhat a persistent ID means.\n\nThis opcode is unlikely to ever be supported by this package.\n\nProtocol 1\n\n\tOBJ\n\nThis opcodes is used in recreating pickled python objects.

The \"From\" receiver on the return value accepts\nthe result of \"Unpickle\" as its actual parameters.\n\nThe keys of the python dictionary are assigned to fields in a structure.\nStructures may specify the tag \"pickle\" on fields. The value of this tag is taken\nas the key name of the Python dictionary value to place in this field. If no\nfield has a matching \"pickle\" tag the fields are looked up by name. If\nthe first character of the key is not uppercase, it is uppercased. If a field\nmatching that name is found, the value in the python dictionary is unpacked\ninto the value of the field within the structure.\n\nA list of python dictionaries can be unpickled into a slice of structures in\nGo.\n\nA homogeneous list of python values can be unpickled into a slice in\nGo with the appropriate element type.\n\nA nested python dictionary is unpickled into nested structures in Go. If a\nfield is of type map[interface{}]interface{} it is of course unpacked into that\nas well.\n\nBy default UnpackInto skips any missing fields and fails if a field's\ntype is not compatible with the object's type.\n\nThis behavior can be changed by setting \"AllowMissingFields\" and\n\"AllowMismatchedFields\" on the return value of UnpackInto before calling\nFrom.\n\n*\/\nfunc Unpickle(reader io.Reader) (interface{}, error) {\n\tvar pm PickleMachine\n\tpm.buf = &bytes.Buffer{}\n\tpm.Reader = reader\n\n\terr := (&pm).execute()\n\tif err != nil {\n\t\treturn nil, err\n\t}\n\n\tif len(pm.Stack) == 0 {\n\t\treturn nil, ErrNoResult\n\t}\n\n\treturn pm.Stack[0], nil\n\n}\n\nvar jumpList = buildEmptyJumpList()\n\nfunc init() {\n\tpopulateJumpList(&jumpList)\n}\n\n\/*\nThis type is returned whenever Unpickle encounters an error in pickled data.\n*\/\ntype PickleMachineError struct {\n\tErr error\n\tStackSize int\n\tMemoSize int\n\tOpcode uint8\n}\n\n\/*\nThis struct is current exposed but not useful.
