{"text":"<commit_before>\/\/ A quick and easy way to setup a RESTful JSON API\n\/\/\n\/\/ Go-Json-Rest is a thin layer on top of net\/http that helps building RESTful JSON APIs easily.\n\/\/ It provides fast URL routing using a Trie based implementation, and helpers to deal\n\/\/ with JSON requests and responses. It is not a high-level REST framework that transparently maps\n\/\/ HTTP requests to procedure calls, on the opposite, you constantly have access to the underlying\n\/\/ net\/http objects.\n\/\/\n\/\/ Example:\n\/\/\n\/\/      package main\n\/\/\n\/\/      import (\n\/\/              \"github.com\/ant0ine\/go-json-rest\"\n\/\/              \"net\/http\"\n\/\/      )\n\/\/\n\/\/      type User struct {\n\/\/              Id   string\n\/\/              Name string\n\/\/      }\n\/\/\n\/\/      func GetUser(w rest.ResponseWriter, req *rest.Request) {\n\/\/              user := User{\n\/\/                      Id:   req.PathParam(\"id\"),\n\/\/                      Name: \"Antoine\",\n\/\/              }\n\/\/              w.WriteJson(&user)\n\/\/      }\n\/\/\n\/\/      func main() {\n\/\/              handler := rest.ResourceHandler{}\n\/\/              handler.SetRoutes(\n\/\/                      rest.Route{\"GET\", \"\/users\/:id\", GetUser},\n\/\/              )\n\/\/              http.ListenAndServe(\":8080\", &handler)\n\/\/      }\n\/\/\n\/\/\n\/\/ Note about the URL routing: Instead of using the usual\n\/\/ \"evaluate all the routes and return the first regexp that matches\" strategy,\n\/\/ it uses a Trie data structure to perform the routing.

The goagen tool\nconsumes the metadata produced from executing the design language to generate service specific code\nthat glues the underlying HTTP server with action specific code and data structures.\n\nThe goa package contains supporting functionality for the generated code including basic request\nand response state management through the Context data structure, error handling via the\nservice and controller ErrorHandler field, middleware support via the Middleware data structure as\nwell as input (and output) format validation algorithms.\n\nRequest Context\n\nThe Context data structure provides access to both the request and response state. It implements\nthe golang.org\/x\/net\/Context interface so that deadlines and cancelation signals may also be\nimplemented with it.\n\nThe request state is accessible through the Get, GetMany and Payload methods which return the values\nof the request parameters, query strings and request body. Action specific contexts wrap Context and\nexpose properly typed fields corresponding to the request parameters and body data structure\ndescriptions appearing in the design.\n\nThe response state can be accessed through the ResponseStatus, ResponseLength and Header methods.\nThe Context type implements the http.ResponseWriter interface and thus action contexts can be used\nin places http.ResponseWriter can. Action contexts provide action specific helper methods that write\nthe responses as described in the design optionally taking an instance of the media type for\nresponses that contain a body.\n\nHere is an example showing an \"update\" action corresponding to following design (extract):\n\n\tResource(\"bottle\", func() {\n\t\tDefaultMedia(Bottle)\n\t\tAction(\"update\", func() {\n\t\t\tParams(func() {\n\t\t\t\tParam(\"bottleID\", Integer)\n\t\t\t})\n\t\t\tPayload(UpdateBottlePayload)\n\t\t\tResponse(OK)\n\t\t\tResponse(NotFound)\n\t\t})\n\t})\n\nThe action signature generated by goagen is:\n\n\ttype BottleController interface {\n\t\tgoa.Controller\n\t\tUpdate(*UpdateBottleContext) error\n\t}\n\nwhere UpdateBottleContext is:\n\n\ttype UpdateBottleContext struct {\n        \t*goa.Context\n        \tBottleID  int\n        \tPayload   *UpdateBottlePayload\n\t}\n\nand implements:\n\n\tfunc (ctx *UpdateBottleContext) OK(resp *Bottle) error\n\tfunc (ctx *UpdateBottleContext) NotFound() error\n\nThe definitions of the Bottle and UpdateBottlePayload data structures are ommitted for brievity.\n\nControllers\n\nThere is one controller interface generated per resource defined via the design language. The\ninterface exposes the controller actions as well as methods to set controller specific middleware\nand error handlers (see below). User code must provide data structures that implement these\ninterfaces when mounting a controller onto a service. The controller data structure should include\nan anonymous field of type *goa.ApplicationController which takes care of implementing the\nmiddleware and error handler handling.\n\nError Handling\n\nThe controller action methods generated by goagen such as the Update method of the BottleController\ninterface shown above all return an error value. The controller or service-wide error handler (if no\ncontroller specific error handler) function is invoked whenever the value returned by a controller\naction is not nil. The handler gets both the request context and the error as argument.\n\nThe default handler implementation returns a response with status code 500 containing the error\nmessage in the body. A different error handler can be specificied using the SetErrorHandler\nfunction on either a controller or service wide. goa comes with an alternative error handler - the\nTerseErrorHandler - which also returns a response with status 500 but does not write the error\nmessage to the body of the response.\n\nMiddleware\n\nA goa middleware is a function that takes and returns a Handler. A Handler is a the low level\nfunction which handles incoming HTTP requests. goagen generates the handlers code so each handler\ncreates the action specific context and calls the controller action with it.\n\nMiddleware can be added to a goa service or a specific controller using the Service type Use method.\ngoa comes with a few stock middleware that handle common needs such as logging, panic recovery or\nusing the RequestID header to trace requests across multiple services.\n\nValidation\n\nThe goa design language documented in the dsl package makes it possible to attach validations to\ndata structure definitions. One specific type of validation consists of defining the format that a\ndata structure string field must follow. Example of formats include email, data time, hostnames etc.\nThe ValidateFormat function provides the implementation for the format validation invoked from the\ncode generated by goagen.\n*\/\npackage goa\n<commit_msg>Update docs<commit_after>\/*\nPackage goa provides the runtime support for goa web services.\n\nCode Generation\n\ngoa service development begins with writing the *design* of a service.

Use Merge() if  you want to change the\n\/\/ underlying set s.\nfunc (s *set) Union(t Interface) Interface {\n\tu := s.Copy()\n\tu.Merge(t)\n\treturn u\n}\n\n\/\/ Merge is like Union, however it modifies the current set it's applied on\n\/\/ with the given t set.\nfunc (s *Set) Merge(t Interface) {\n\ts.l.Lock()\n\tdefer s.l.Unlock()\n\n\tt.Each(func(item interface{}) bool {\n\t\ts.m[item] = keyExists\n\t\treturn true\n\t})\n}\n\n\/\/ Merge is like Union, however it modifies the current set it's applied on\n\/\/ with the given t set.\nfunc (s *set) Merge(t Interface) {\n\tt.Each(func(item interface{}) bool {\n\t\ts.m[item] = keyExists\n\t\treturn true\n\t})\n}\n\n\/\/ it's not the opposite of Merge.\n\/\/ Separate removes the set items containing in t from set s. Please aware that\nfunc (s *set) Separate(t Interface) {\n\ts.Remove(t.List()...)\n}\n\n\/\/ Intersection returns a new set which contains items which is in both s and t.\nfunc (s *set) Intersection(t Interface) Interface {\n\tu := s.Copy()\n\tu.Separate(u.Difference(t))\n\treturn u\n}\n\n\/\/ Difference returns a new set which contains items which are in s but not in t.\nfunc (s *set) Difference(t Interface) Interface {\n\tu := s.Copy()\n\tu.Separate(t)\n\treturn u\n}\n\n\/\/ SymmetricDifference returns a new set which s is the difference of items which are in\n\/\/ one of either, but not in both.\nfunc (s *set) SymmetricDifference(t Interface) Interface {\n\tu := s.Difference(t)\n\tv := t.Difference(s)\n\treturn u.Union(v)\n}\n\n\/\/ StringSlice is a helper function that returns a slice of strings of s. If\n\/\/ the set contains mixed types of items only items of type string are returned.\nfunc (s *set) StringSlice() []string {\n\tslice := make([]string, 0)\n\tfor _, item := range s.List() {\n\t\tv, ok := item.(string)\n\t\tif !ok {\n\t\t\tcontinue\n\t\t}\n\n\t\tslice = append(slice, v)\n\t}\n\treturn slice\n}\n\n\/\/ IntSlice is a helper function that returns a slice of ints of s. If\n\/\/ the set contains mixed types of items only items of type int are returned.\nfunc (s *set) IntSlice() []int {\n\tslice := make([]int, 0)\n\tfor _, item := range s.List() {\n\t\tv, ok := item.(int)\n\t\tif !ok {\n\t\t\tcontinue\n\t\t}\n\n\t\tslice = append(slice, v)\n\t}\n\treturn slice\n}\n\n\/\/ Union is the merger of multiple sets. It returns a new set with the\n\/\/ element in combined in all sets that are passed. Unlike the Union() method\n\/\/ you can use this function seperatly with multiple sets. If no items are\n\/\/ passed an empty set is returned.\nfunc Union(sets ...Interface) Interface {\n\tu := New()\n\tfor _, set := range sets {\n\t\tset.Each(func(item interface{}) bool {\n\t\t\tu.m[item] = keyExists\n\t\t\treturn true\n\t\t})\n\t}\n\n\treturn u\n}\n\n\/\/ Difference returns a new set which contains items which are in in the first\n\/\/ set but not in the others. Unlike the Difference() method you can use this\n\/\/ function seperatly with multiple sets. If no items are passed an empty set\n\/\/ is returned.\nfunc Difference(sets ...Interface) Interface {\n\tif len(sets) == 0 {\n\t\treturn New()\n\t}\n\n\ts := sets[0].Copy()\n\tfor _, set := range sets[1:] {\n\t\ts.Separate(set) \/\/ seperate is thread safe\n\t}\n\treturn s\n}\n<|endoftext|>"}

{"text":"<commit_before>\/*\n\nScollector is a metric collection agent for OpenTSDB 2.0 and Bosun.\n\ntcollector (https:\/\/github.com\/OpenTSDB\/tcollector) is OpenTSDB's data\ncollection framework built for OpenTSDB 1.0. scollector aims to be tcollector\nfor OpenTSDB 2.0 and is one method of sending data to Bosun (http:\/\/bosun.org\/)\nfor monitoring.\n\nUnlike tcollector, scollector is a single binary where all collectors are\ncompiled into scollector itself. scollector supports external collectors, but\nyour goal should be to use those temporarily until the go version is written or\nthe target system send data directly to OpenTSDB or Bosun. scollector has\nnative collectors for Linux, Darwin, and Windows and can pull data from other\nsystems such as AWS, SNMP, and vSphere.\n\nUsage:\n\tscollector [flag]\n\nThe flags are:\n\n\t-h=\"\"\n\t\tOpenTSDB or Bosun host. Overrides Host in conf file.\n\t-f=\"\"\n\t\tFilters collectors matching these terms, separated by\n\t\tcomma. Overrides Filter in conf file.\n\t-b=0\n\t\tOpenTSDB batch size. Default is 500.\n\t-conf=\"\"\n\t\tLocation of configuration file. Defaults to scollector.toml in directory of\n\t\tthe scollector executable.\n\t-l\n\t\tList available collectors (after Filter is applied).\n\t-m\n\t\tDisable sending of metadata.\n\t-version\n\t\tPrints the version and exits.\n\nAdditional flags on Windows:\n\t-winsvc=\"\"\n\t\tWindows Service management; can be: install, remove, start, stop\n\nDebug flags:\n\t-d\n\t\tenables debug output\n\t-p\n\t\tprint to screen instead of sending to a host\n\t-fake=0\n\t\tgenerates X fake data points per second on the test.fake metric\n\nThe only required paremeter is the host, which may be specified in the conf\nfile or with -h.\n\nWarning\n\nscollector has not been tested outside of the Stack Exchange environment, and\nthus may act incorrectly elsewhere.\n\nscollector requires the new HTTP API of OpenTSDB 2.1 with gzip support. Ensure\nthat is in use if not using the OpenTSDB docker image.\n\nLogs\n\nIf started with -p or -d, scollector logs to Stdout. Otherwise, on Unixes,\nscollector logs to syslog. On Windows when started as a service, the Event Log\nis used.\n\nExternal Collectors\n\nSee http:\/\/bosun.org\/scollector\/external-collectors for details about using\nexternal scripts or programs to collect metrics.\n\nConfiguration File\n\nIf scollector.toml exists in the same directory as the scollector\nexecutable or is specified via the -conf=\"\" flag, it's content\nwill be used to set configuration flags. The format is toml\n(https:\/\/github.com\/toml-lang\/toml\/blob\/master\/versions\/en\/toml-v0.2.0.md).\nAvailable keys are:\n\nHost (string): the OpenTSDB or Bosun host to send data, supports TLS and\nHTTP Basic Auth.\n\n\tHost = \"https:\/\/user:password@example.com\/\"\n\nFullHost (boolean): enables full hostnames: doesn't truncate to first \".\".\n\nColDir (string): is the external collectors directory.\n\nTags (table of strings): are added to every datapoint. If a collector specifies\nthe same tag key, this one will be overwritten. The host tag is not supported.\n\nHostname (string): overrides the system hostname.\n\nDisableSelf (boolean): disables sending of scollector self metrics.\n\nFreq (integer): is the default frequency in seconds for most collectors.\n\nBatchSize (integer): is the number of metrics that will be sent in each batch.\nDefault is 500.\n\nFilter (array of string): filters collectors matching these terms.\n\nPProf (string): optional IP:Port binding to be used for debugging with pprof.\nExamples: localhost:6060 for loopback or :6060 for all IP addresses.\n\nCollector configuration keys\n\nFollowing are configurations for collectors that do not autodetect.\n\nKeepalivedCommunity (string): if not empty, enables the Keepalived collector\nwith the specified community.\n\n\tKeepalivedCommunity = \"keepalivedcom\"\n\nHAProxy (array of table, keys are User, Password, Instances): HAProxy instances\nto poll.

Overrides Host in conf file.\n\t-f=\"\"\n\t\tFilters collectors matching these terms, separated by\n\t\tcomma. Overrides Filter in conf file.\n\t-b=0\n\t\tOpenTSDB batch size. Default is 500.\n\t-conf=\"\"\n\t\tLocation of configuration file. Defaults to scollector.toml in directory of\n\t\tthe scollector executable.\n\t-l\n\t\tList available collectors (after Filter is applied).\n\t-m\n\t\tDisable sending of metadata.\n\t-version\n\t\tPrints the version and exits.\n\nAdditional flags on Windows:\n\t-winsvc=\"\"\n\t\tWindows Service management; can be: install, remove, start, stop\n\nDebug flags:\n\t-d\n\t\tenables debug output\n\t-p\n\t\tprint to screen instead of sending to a host\n\t-fake=0\n\t\tgenerates X fake data points per second on the test.fake metric\n\nThe only required paremeter is the host, which may be specified in the conf\nfile or with -h.\n\nWarning\n\nscollector has not been tested outside of the Stack Exchange environment, and\nthus may act incorrectly elsewhere.\n\nscollector requires the new HTTP API of OpenTSDB 2.1 with gzip support. Ensure\nthat is in use if not using the OpenTSDB docker image.\n\nLogs\n\nIf started with -p or -d, scollector logs to Stdout. Otherwise, on Unixes,\nscollector logs to syslog. On Windows when started as a service, the Event Log\nis used.\n\nExternal Collectors\n\nSee http:\/\/bosun.org\/scollector\/external-collectors for details about using\nexternal scripts or programs to collect metrics.\n\nConfiguration File\n\nIf scollector.toml exists in the same directory as the scollector\nexecutable or is specified via the -conf=\"\" flag, it's content\nwill be used to set configuration flags. The format is toml\n(https:\/\/github.com\/toml-lang\/toml\/blob\/master\/versions\/en\/toml-v0.2.0.md).\nAvailable keys are:\n\nHost (string): the OpenTSDB or Bosun host to send data, supports TLS and\nHTTP Basic Auth.\n\n\tHost = \"https:\/\/user:password@example.com\/\"\n\nFullHost (boolean): enables full hostnames: doesn't truncate to first \".\".\n\nColDir (string): is the external collectors directory.\n\nTags (table of strings): are added to every datapoint. If a collector specifies\nthe same tag key, this one will be overwritten. The host tag is not supported.\n\nHostname (string): overrides the system hostname.\n\nDisableSelf (boolean): disables sending of scollector self metrics.\n\nFreq (integer): is the default frequency in seconds for most collectors.\n\nBatchSize (integer): is the number of metrics that will be sent in each batch.\nDefault is 500.\n\nFilter (array of string): filters collectors matching these terms.\n\nPProf (string): optional IP:Port binding to be used for debugging with pprof.\nExamples: localhost:6060 for loopback or :6060 for all IP addresses.\n\nCollector configuration keys\n\nFollowing are configurations for collectors that do not autodetect.\n\nKeepalivedCommunity (string): if not empty, enables the Keepalived collector\nwith the specified community.\n\n\tKeepalivedCommunity = \"keepalivedcom\"\n\nHAProxy (array of table, keys are User, Password, Instances): HAProxy instances\nto poll.

Includes are parsed first (before\nlayouts and regular templates). Includes should contain .tmpl files for things\nlike the <head> section, which are shared between different layouts, or other\ncomponents that are shared between different regular templates.

No .tmpl file in the\nlayouts directory can conflict with any other .tmpl file (e.g. they cannot\ndeclare sub-templates of the same name). If includes were also provided, all\nincludes will be added to the parse tree for each layout via the\ntemplate.AddParseTree method. Therefore a layout can reference any template in\nincludes.

All layouts and includes\n(if any) are added to the parse tree for each template via the\ntemplate.AddParseTree method. Therefore templates can reference both layouts and\nincludes.

It is not returned\n\/\/ as an error by any function.\nvar SkipDir = errors.New(\"skip this directory\")\n\n\/\/ WalkDirFunc is the type of the function called by WalkDir to visit\n\/\/ each each file or directory.\n\/\/\n\/\/ The path argument contains the argument to Walk as a prefix.\n\/\/ That is, if Walk is called with root argument \"dir\" and finds a file\n\/\/ named \"a\" in that directory, the walk function will be called with\n\/\/ argument \"dir\/a\".\n\/\/\n\/\/ The directory and file are joined with Join, which may clean the\n\/\/ directory name: if Walk is called with the root argument \"x\/..\/dir\"\n\/\/ and finds a file named \"a\" in that directory, the walk function will\n\/\/ be called with argument \"dir\/a\", not \"x\/..\/dir\/a\".\n\/\/\n\/\/ The d argument is the fs.DirEntry for the named path.\n\/\/\n\/\/ The error result returned by the function controls how WalkDir\n\/\/ continues. If the function returns the special value SkipDir, WalkDir\n\/\/ skips the current directory (path if d.IsDir() is true, otherwise\n\/\/ path's parent directory). Otherwise, if the function returns a non-nil\n\/\/ error, WalkDir stops entirely and returns that error.\n\/\/\n\/\/ The err argument reports an error related to path, signaling that\n\/\/ WalkDir will not walk into that directory.

When an FD needs to wait,\n\/\/ send the fd on s.cr (for a read) or s.cw (for a write) to pass the\n\/\/ request to the poll server.  Then receive on fd.cr\/fd.cw.\n\/\/ When the pollServer finds that i\/o on FD should be possible\n\/\/ again, it will send fd on fd.cr\/fd.cw to wake any waiting processes.\n\/\/ This protocol is implemented as s.WaitRead() and s.WaitWrite().\n\/\/\n\/\/ There is one subtlety: when sending on s.cr\/s.cw, the\n\/\/ poll server is probably in a system call, waiting for an fd\n\/\/ to become ready.  It's not looking at the request channels.\n\/\/ To resolve this, the poll server waits not just on the FDs it has\n\/\/ been given but also its own pipe.  After sending on the\n\/\/ buffered channel s.cr\/s.cw, WaitRead\/WaitWrite writes a\n\/\/ byte to the pipe, causing the pollServer's poll system call to\n\/\/ return.  In response to the pipe being readable, the pollServer\n\/\/ re-polls its request channels.\n\/\/\n\/\/ Note that the ordering is \"send request\" and then \"wake up server\".\n\/\/ If the operations were reversed, there would be a race: the poll\n\/\/ server might wake up and look at the request channel, see that it\n\/\/ was empty, and go back to sleep, all before the requester managed\n\/\/ to send the request.  Because the send must complete before the wakeup,\n\/\/ the request channel must be buffered.  A buffer of size 1 is sufficient\n\/\/ for any request load.  If many processes are trying to submit requests,\n\/\/ one will succeed, the pollServer will read the request, and then the\n\/\/ channel will be empty for the next process's request.  A larger buffer\n\/\/ might help batch requests.\n\ntype pollServer struct {\n\tcr, cw chan *netFD;\t\/\/ buffered >= 1\n\tpr, pw *os.File;\n\tpending map[int64] *netFD;\n\tpoll *pollster;\t\/\/ low-level OS hooks\n\tdeadline int64;\t\/\/ next deadline (nsec since 1970)\n}\nfunc (s *pollServer) Run();\n\nfunc newPollServer() (s *pollServer, err *os.Error) {\n\ts = new(pollServer);\n\ts.cr = make(chan *netFD, 1);\n\ts.cw = make(chan *netFD, 1);\n\tif s.pr, s.pw, err = os.Pipe();

When an FD needs to wait,\n\/\/ send the fd on s.cr (for a read) or s.cw (for a write) to pass the\n\/\/ request to the poll server.  Then receive on fd.cr\/fd.cw.\n\/\/ When the pollServer finds that i\/o on FD should be possible\n\/\/ again, it will send fd on fd.cr\/fd.cw to wake any waiting processes.\n\/\/ This protocol is implemented as s.WaitRead() and s.WaitWrite().\n\/\/\n\/\/ There is one subtlety: when sending on s.cr\/s.cw, the\n\/\/ poll server is probably in a system call, waiting for an fd\n\/\/ to become ready.  It's not looking at the request channels.\n\/\/ To resolve this, the poll server waits not just on the FDs it has\n\/\/ been given but also its own pipe.  After sending on the\n\/\/ buffered channel s.cr\/s.cw, WaitRead\/WaitWrite writes a\n\/\/ byte to the pipe, causing the pollServer's poll system call to\n\/\/ return.  In response to the pipe being readable, the pollServer\n\/\/ re-polls its request channels.\n\/\/\n\/\/ Note that the ordering is \"send request\" and then \"wake up server\".\n\/\/ If the operations were reversed, there would be a race: the poll\n\/\/ server might wake up and look at the request channel, see that it\n\/\/ was empty, and go back to sleep, all before the requester managed\n\/\/ to send the request.  Because the send must complete before the wakeup,\n\/\/ the request channel must be buffered.  A buffer of size 1 is sufficient\n\/\/ for any request load.  If many processes are trying to submit requests,\n\/\/ one will succeed, the pollServer will read the request, and then the\n\/\/ channel will be empty for the next process's request.  A larger buffer\n\/\/ might help batch requests.\n\ntype pollServer struct {\n\tcr, cw chan *netFD;\t\/\/ buffered >= 1\n\tpr, pw *os.File;\n\tpending map[int64] *netFD;\n\tpoll *pollster;\t\/\/ low-level OS hooks\n\tdeadline int64;\t\/\/ next deadline (nsec since 1970)\n}\nfunc (s *pollServer) Run();\n\nfunc newPollServer() (s *pollServer, err *os.Error) {\n\ts = new(pollServer);\n\ts.cr = make(chan *netFD, 1);\n\ts.cw = make(chan *netFD, 1);\n\tif s.pr, s.pw, err = os.Pipe();

The main table will need to get a slightly different collation table as the one used by regtest, as the regtest is based on the standard UCA DUCET, while the locale-specific tables are all based on a CLDR root table. This change allows changing the table without affecting the regression test.<commit_after>\/\/ Copyright 2012 The Go Authors.

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.\n\tFinishSetUp(state *State)\n\n\t\/\/CheckGameFinished should return true if the game is finished, and who\n\t\/\/the winners are.

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.\n\tProposeFixUpMove(state *State) Move\n\n\t\/\/DefaultNumPlayers returns the number of users that this game defaults to.\n\t\/\/For example, for tictactoe, it will be 2.

This means that if different players have\n\t\/\/very different roles in a game, there might be many properties that are\n\t\/\/not in use for any given player. The simple properties (ints, bools,\n\t\/\/strings) should all be their zero-value. Importantly, all Stacks should\n\t\/\/be non- nil, because an initialized struct contains information about\n\t\/\/things like MaxSize, Size, and a reference to the deck they are\n\t\/\/affiliated with. Game methods that use these will fail if the State\n\t\/\/objects return have uninitialized stacks.

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.\n\tFinishSetUp(state *State)\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 *State) (finished bool, winners []int)\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.\n\tProposeFixUpMove(state *State) Move\n\n\t\/\/DefaultNumPlayers returns the number of users that this game defaults to.\n\t\/\/For example, for tictactoe, it will be 2. If 0 is provided to\n\t\/\/game.SetUp(), we wil use this value insteadp.\n\tDefaultNumPlayers() 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 game's SetUp will fail. Game.SetUp\n\t\/\/will automatically reject a numPlayers that does not result in at least\n\t\/\/one player existing.\n\tLegalNumPlayers(numPlayers int) bool\n\n\t\/\/EmptyGameState and EmptyPlayerState are called to get an instantiation\n\t\/\/of the concrete game\/player structs that your package defines. This is\n\t\/\/used both to create the initial state, but also to inflate states from\n\t\/\/the database. These methods should always return the underlying same\n\t\/\/type of struct when called. This means that if different players have\n\t\/\/very different roles in a game, there might be many properties that are\n\t\/\/not in use for any given player. The simple properties (ints, bools,\n\t\/\/strings) should all be their zero-value. Importantly, all Stacks should\n\t\/\/be non- nil, because an initialized struct contains information about\n\t\/\/things like MaxSize, Size, and a reference to the deck they are\n\t\/\/affiliated with. Game methods that use these will fail if the State\n\t\/\/objects return have uninitialized stacks. Since these two methods are\n\t\/\/always required and always specific to each game type,\n\t\/\/DefaultGameDelegate does not implement them, as an extra reminder that\n\t\/\/you must implement them yourself.\n\tEmptyGameState() GameState\n\t\/\/EmptyPlayerState is similar to EmptyGameState, but playerIndex is the\n\t\/\/value that this PlayerState must return when its PlayerIndex() is\n\t\/\/called.\n\tEmptyPlayerState(playerIndex int) PlayerState\n\n\t\/\/StateSanitizationPolicy returns the policy for sanitizing states in this\n\t\/\/game. The policy should not change over time. See StatePolicy for more\n\t\/\/on how sanitization policies are calculated and applied.\n\tStateSanitizationPolicy() *StatePolicy\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 *State) 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\/\/DefaultGameDelegate is a struct that implements stubs for all of\n\/\/GameDelegate's methods. This makes it easy to override just one or two\n\/\/methods by creating your own struct that anonymously embeds this one. You\n\/\/almost certainly want to override StartingState.\ntype DefaultGameDelegate struct {\n\tmanager *GameManager\n}\n\nfunc (d *DefaultGameDelegate) Diagram(state *State) string {\n\treturn \"This should be overriden to render a reasonable state here\"\n}\n\nfunc (d *DefaultGameDelegate) Name() string {\n\treturn \"default\"\n}\n\nfunc (d *DefaultGameDelegate) DisplayName() string {\n\treturn \"Default Game\"\n}\n\nfunc (d *DefaultGameDelegate) Manager() *GameManager {\n\treturn d.manager\n}\n\nfunc (d *DefaultGameDelegate) SetManager(manager *GameManager) {\n\td.manager = manager\n}\n\n\/\/The Default ProposeFixUpMove runs through all moves in FixUpMoves, in order,\n\/\/and returns the first one that is legal at the current state. In many cases,\n\/\/this behavior should be suficient and need not be overwritten. Be extra sure\n\/\/that your FixUpMoves have a conservative Legal function, otherwise you could\n\/\/get a panic from applying too many FixUp moves.\nfunc (d *DefaultGameDelegate) ProposeFixUpMove(state *State) Move {\n\tfor _, move := range d.Manager().FixUpMoves() {\n\t\tmove.DefaultsForState(state)\n\t\tif err := move.Legal(state); err == nil {\n\t\t\t\/\/Found it!\n\t\t\treturn move\n\t\t}\n\t}\n\t\/\/No moves apply now.\n\treturn nil\n}\n\nfunc (d *DefaultGameDelegate) DistributeComponentToStarterStack(state *State, c *Component) error {\n\t\/\/The stub returns an error, because if this is called that means there\n\t\/\/was a component in the deck.

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 is composed of a list 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 = '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 parent 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 (!) expression\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 a 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\nCharacter class matcher\n\nAny matcher\n\nCode block\n\nUsing the generated parser\n\nTODO: Start rule is the first rule. Example package to document the exported symbols.\n\nError reporting\n\nTODO: List of errors, ParserError type, grammar example to handle common error (like\nnon-terminated string literal), panic.\n\n*\/\npackage main\n<|endoftext|>"}

Callers must still Close the file handle\n\/\/ as usual.\ntype safeFile struct {\n\t*os.File\n\tfinalName string\n}\n\n\/\/ Commit syncs the file and then renames it to the intended final filename.\n\/\/ Writing to the file after calling Commit will succeed but will write to the\n\/\/ final file location (sf.Name() will deceptively still point to the old file\n\/\/ location).  Therefore it is recommended that the file handle be closed\n\/\/ immediately after calling Commit. Note that the file must not be closed\n\/\/ before calling commit as this will cause the sync to fail.\nfunc (sf *safeFile) Commit() error {\n\terr := sf.Sync()\n\tif err != nil {\n\t\treturn err\n\t}\n\terr = sf.Close()\n\tif err != nil {\n\t\treturn err\n\t}\n\treturn os.Rename(sf.finalName+\"_temp\", sf.finalName)\n}\n\n\/\/ NewSafeFile returns a file that can atomically be written to disk,\n\/\/ minimizing the risk of corruption.\nfunc NewSafeFile(filename string) (*safeFile, error) {\n\tfile, err := os.Create(filename + \"_temp\")\n\tif err != nil {\n\t\treturn nil, err\n\t}\n\n\t\/\/ Get the absolute path of the filename so that calling os.Chdir in\n\t\/\/ between calling NewSafeFile and calling safeFile.Commit does not change\n\t\/\/ the final file path.\n\tabsFilename, err := filepath.Abs(filename)\n\tif err != nil {\n\t\treturn nil, err\n\t}\n\n\treturn &safeFile{file, absFilename}, nil\n}\n<|endoftext|>"}

(2) Collection errors with\n\t\/\/ no effect on the HTTP status code because ErrorHandling is set to\n\t\/\/ ContinueOnError.\n\tRegistry prometheus.Registerer\n\t\/\/ If DisableCompression is true, the handler will never compress the\n\t\/\/ response, even if requested by the client.\n\tDisableCompression bool\n\t\/\/ The number of concurrent HTTP requests is limited to\n\t\/\/ MaxRequestsInFlight.

Note that with the current\n\t\/\/ implementation, reaching the timeout simply ends the HTTP requests as\n\t\/\/ described above (and even that only if sending of the body hasn't\n\t\/\/ started yet), while the bulk work of gathering all the metrics keeps\n\t\/\/ running in the background (with the eventual result to be thrown\n\t\/\/ away).

Note that the scrapes-in-flight gauge\n\/\/ will contain the scrape by which it is exposed, while the scrape counter will\n\/\/ only get incremented after the scrape is complete (as only then the status\n\/\/ code is known).

In this case, it is highly\n\t\/\/ recommended to provide other means of detecting errors: By setting an\n\t\/\/ ErrorLog in HandlerOpts, the errors are logged. By providing a\n\t\/\/ Registry in HandlerOpts, the exposed metrics include an error counter\n\t\/\/ \"promhttp_metric_handler_errors_total\", which can be used for\n\t\/\/ alerts.\n\tContinueOnError\n\t\/\/ Panic upon the first error encountered (useful for \"crash only\" apps).\n\tPanicOnError\n)\n\n\/\/ Logger is the minimal interface HandlerOpts needs for logging.

There are two typical cases:\n\t\/\/ (1) Encoding errors that only happen after streaming of the HTTP body\n\t\/\/ has already started (and the status code 200 has been sent). This\n\t\/\/ should only happen with custom collectors. (2) Collection errors with\n\t\/\/ no effect on the HTTP status code because ErrorHandling is set to\n\t\/\/ ContinueOnError.\n\tRegistry prometheus.Registerer\n\t\/\/ If DisableCompression is true, the handler will never compress the\n\t\/\/ response, even if requested by the client.\n\tDisableCompression bool\n\t\/\/ The number of concurrent HTTP requests is limited to\n\t\/\/ MaxRequestsInFlight.

Note that with the current\n\t\/\/ implementation, reaching the timeout simply ends the HTTP requests as\n\t\/\/ described above (and even that only if sending of the body hasn't\n\t\/\/ started yet), while the bulk work of gathering all the metrics keeps\n\t\/\/ running in the background (with the eventual result to be thrown\n\t\/\/ away). Until the implementation is improved, it is recommended to\n\t\/\/ implement a separate timeout in potentially slow Collectors.\n\tTimeout time.Duration\n\t\/\/ If true, the experimental OpenMetrics encoding is added to the\n\t\/\/ possible options during content negotiation. Note that Prometheus\n\t\/\/ 2.5.0+ will negotiate OpenMetrics as first priority. OpenMetrics is\n\t\/\/ the only way to transmit exemplars. However, the move to OpenMetrics\n\t\/\/ is not completely transparent. Most notably, the values of \"quantile\"\n\t\/\/ labels of Summaries and \"le\" labels of Histograms are formatted with\n\t\/\/ a trailing \".0\" if they would otherwise look like integer numbers\n\t\/\/ (which changes the identity of the resulting series on the Prometheus\n\t\/\/ server).\n\tEnableOpenMetrics bool\n}\n\n\/\/ gzipAccepted returns whether the client will accept gzip-encoded content.\nfunc gzipAccepted(header http.Header) bool {\n\ta := header.Get(acceptEncodingHeader)\n\tparts := strings.Split(a, \",\")\n\tfor _, part := range parts {\n\t\tpart = strings.TrimSpace(part)\n\t\tif part == \"gzip\" || strings.HasPrefix(part, \"gzip;\") {\n\t\t\treturn true\n\t\t}\n\t}\n\treturn false\n}\n\n\/\/ httpError removes any content-encoding header and then calls http.Error with\n\/\/ the provided error and http.StatusInternalServerError.

{"text":"<commit_before>\/\/ Package metrics provides a framework for application instrumentation.

one:\n\/\/    • > IAM and Admin > Service Accounts\n\/\/    • Under the needed Service Account > Actions > Manage Keys\n\/\/    • Add Key > Create New Key\n\/\/    • Select JSON, and the click Create\n\/\/ • Look for an available VM Instance, or create one- > Compute > Compute Engine > VM Instances\n\/\/ • On the VM Instance, click the SSH Button.  Then upload:\n\/\/    • Your Service Account Key File\n\/\/    • This script, along with setup.sh\n\/\/    • A copy of env.conf, containing the required environment variables (see existing skeleton)\/\n\/\/ • Set your environment variables (Usually this will be `source env.conf`)\n\/\/ • Ensure that your VM is properly set up to run the integration test e.g.\n\/\/    • wget -c
