Each time a client sends a request for one or\n\/\/ more metrics backed by variables within a particular region, tricorder\n\/\/ calls that region’s update function one time before reading any of the\n\/\/ variables in that region to to respond to the client.

{"text":"<commit_before>\/\/ Package goawk is an implementation of AWK written in Go.\n\/\/\n\/\/ You can use the command-line \"goawk\" command or run AWK from your\n\/\/ Go programs using the \"interp\" package. The command-line program\n\/\/ has the same interface as regular awk:\n\/\/\n\/\/     goawk [-F fs] [-v var=value] [-f progfile | 'prog'] [file ...]\n\/\/\n\/\/ The -F flag specifies the field separator (the default is to split\n\/\/ on whitespace). The -v flag allows you to set a variable to a\n\/\/ given value (multiple -v flags allowed).

Tracker may be nil.\n\/\/ The 'pkg' is the full package name, in which the Namer is used - all\n\/\/ types from that package will be referenced by just type name without\n\/\/ referencing the package.\n\/\/\n\/\/ For example, if the type is map[string]int, a raw namer will literally\n\/\/ return \"map[string]int\".\n\/\/\n\/\/ Or if the type, in package foo, is \"type Bar struct { ... }\", then the raw\n\/\/ namer will return \"foo.Bar\" as the name of the type, and if 'tracker' was\n\/\/ not nil, will record that package foo needs to be imported.\nfunc NewRawNamer(pkg string, tracker ImportTracker) *rawNamer {\n\treturn &rawNamer{pkg: pkg, tracker: tracker}\n}\n\n\/\/ Names is a map from Type to name, as defined by some Namer.\ntype Names map[*types.Type]string\n\n\/\/ Namer takes a type, and assigns a name.\n\/\/\n\/\/ The purpose of this complexity is so that you can assign coherent\n\/\/ side-by-side systems of names for the types. For example, you might want a\n\/\/ public interface, a private implementation struct, and also to reference\n\/\/ literally the type name.\n\/\/\n\/\/ Note that it is safe to call your own Name() function recursively to find\n\/\/ the names of keys, elements, etc. This is because anonymous types can't have\n\/\/ cycles in their names, and named types don't require the sort of recursion\n\/\/ that would be problematic.\ntype Namer interface {\n\tName(*types.Type) string\n}\n\n\/\/ NameSystems is a map of a system name to a namer for that system.\ntype NameSystems map[string]Namer\n\n\/\/ NameStrategy is a general Namer. The easiest way to use it is to copy the\n\/\/ Public\/PrivateNamer variables, and modify the members you wish to change.\n\/\/\n\/\/ The Name method produces a name for the given type, of the forms:\n\/\/ Anonymous types: <Prefix><Type description><Suffix>\n\/\/ Named types: <Prefix><Optional Prepended Package name(s)><Original name><Suffix>\n\/\/\n\/\/ In all cases, every part of the name is run through the capitalization\n\/\/ functions.\n\/\/\n\/\/ The IgnoreWords map can be set if you have directory names that are\n\/\/ semantically meaningless for naming purposes, e.g. \"proto\".\n\/\/\n\/\/ Prefix and Suffix can be used to disambiguate parallel systems of type\n\/\/ names. For example, if you want to generate an interface and an\n\/\/ implementation, you might want to suffix one with \"Interface\" and the other\n\/\/ with \"Implementation\". Another common use-- if you want to generate private\n\/\/ types, and one of your source types could be \"string\", you can't use the\n\/\/ default lowercase private namer. You'll have to add a suffix or prefix.\ntype NameStrategy struct {\n\tPrefix, Suffix string\n\tJoin           func(pre string, parts []string, post string) string\n\n\t\/\/ Add non-meaningful package directory names here (e.g. \"proto\") and\n\t\/\/ they will be ignored.\n\tIgnoreWords map[string]bool\n\n\t\/\/ If > 0, prepend exactly that many package directory names (or as\n\t\/\/ many as there are).

{"text":"<commit_before>\/\/ Package circuit implements the Circuit Breaker pattern. It will wrap\n\/\/ a function call (typically one which uses remote services) and monitors for\n\/\/ failures and\/or time outs. When a threshold of failures or time outs has been\n\/\/ reached, future calls to the function will not run. During this state, the\n\/\/ breaker will periodically allow the function to run and, if it is successful,\n\/\/ will start running the function again.\n\/\/\n\/\/ Circuit includes three types of circuit breakers:\n\/\/\n\/\/ A Threshold Breaker will trip when the failure count reaches a given threshold.\n\/\/ It does not matter how long it takes to reach the threshold and the failures do\n\/\/ not need to be consecutive.\n\/\/\n\/\/ A Consecutive Breaker will trip when the consecutive failure count reaches a given\n\/\/ threshold. It does not matter how long it takes to reach the threshold, but the\n\/\/ failures do need to be consecutive.\n\/\/\n\/\/\n\/\/ When wrapping blocks of code with a Breaker's Call() function, a time out can be\n\/\/ specified.

It will wrap\n\/\/ a function call (typically one which uses remote services) and monitors for\n\/\/ failures and\/or time outs. When a threshold of failures or time outs has been\n\/\/ reached, future calls to the function will not run. During this state, the\n\/\/ breaker will periodically allow the function to run and, if it is successful,\n\/\/ will start running the function again.\n\/\/\n\/\/ Circuit includes three types of circuit breakers:\n\/\/\n\/\/ A Threshold Breaker will trip when the failure count reaches a given threshold.\n\/\/ It does not matter how long it takes to reach the threshold and the failures do\n\/\/ not need to be consecutive.\n\/\/\n\/\/ A Consecutive Breaker will trip when the consecutive failure count reaches a given\n\/\/ threshold. It does not matter how long it takes to reach the threshold, but the\n\/\/ failures do need to be consecutive.\n\/\/\n\/\/\n\/\/ When wrapping blocks of code with a Breaker's Call() function, a time out can be\n\/\/ specified. If the time out is reached, the breaker's Fail() function will be called.\n\/\/\n\/\/\n\/\/ Other types of circuit breakers can be easily built by creating a Breaker and\n\/\/ adding a custom TripFunc. A TripFunc is called when a Breaker Fail()s and receives\n\/\/ the breaker as an argument. It then returns true or false to indicate whether the\n\/\/ breaker should trip.\n\/\/\n\/\/ The package also provides a wrapper around an http.Client that wraps all of\n\/\/ the http.Client functions with a Breaker.\n\/\/\npackage circuit\n\nimport (\n\t\"errors\"\n\t\"sync\"\n\t\"sync\/atomic\"\n\t\"time\"\n\n\t\"github.com\/cenk\/backoff\"\n\t\"github.com\/facebookgo\/clock\"\n)\n\n\/\/ BreakerEvent indicates the type of event received over an event channel\ntype BreakerEvent int\n\nconst (\n\t\/\/ BreakerTripped is sent when a breaker trips\n\tBreakerTripped BreakerEvent = iota\n\n\t\/\/ BreakerReset is sent when a breaker resets\n\tBreakerReset BreakerEvent = iota\n\n\t\/\/ BreakerFail is sent when Fail() is called\n\tBreakerFail BreakerEvent = iota\n\n\t\/\/ BreakerReady is sent when the breaker enters the half open state and is ready to retry\n\tBreakerReady BreakerEvent = iota\n)\n\n\/\/ ListenerEvent includes a reference to the circuit breaker and the event.\ntype ListenerEvent struct {\n\tCB    *Breaker\n\tEvent BreakerEvent\n}\n\ntype state int\n\nconst (\n\topen     state = iota\n\thalfopen state = iota\n\tclosed   state = iota\n)\n\nvar (\n\tdefaultInitialBackOffInterval = 500 * time.Millisecond\n\tdefaultBackoffMaxElapsedTime  = 0 * time.Second\n)\n\n\/\/ Error codes returned by Call\nvar (\n\tErrBreakerOpen    = errors.New(\"breaker open\")\n\tErrBreakerTimeout = errors.New(\"breaker time out\")\n)\n\n\/\/ TripFunc is a function called by a Breaker's Fail() function and determines whether\n\/\/ the breaker should trip.

The chart argument can be one of:\n - a chart reference('stable\/mariadb'); use '--version' and '--devel' flags for versions other than latest,\n - a path to a chart directory,\n - a packaged chart,\n - a fully qualified URL.\n\nTo customize the chart values, use any of\n - '--values'\/'-f' to pass in a yaml file holding settings,\n - '--set' to provide one or more key=val pairs directly,\n - '--set-string' to provide key=val forcing val to be stored as a string,\n - '--set-file' to provide key=path to read a single large value from a file at path.\n\nTo edit or append to the existing customized values, add the\n '--reuse-values' flag, otherwise any existing customized values are ignored.\n\nIf no chart value arguments are provided on the command line, any existing customized values are carried\nforward. If you want to revert to just the values provided in the chart, use the '--reset-values' flag.\n\nYou can specify any of the chart value flags multiple times. The priority will be given to the last\n(right-most) value specified. For example, if both myvalues.yaml and override.yaml contained a key\ncalled 'Test', the value set in override.yaml would take precedence:\n\n\t$ helm upgrade -f myvalues.yaml -f override.yaml redis .\/redis\n\nNote that the key name provided to the '--set', '--set-string' and '--set-file' flags can reference\nstructure elements. Examples:\n  - mybool=TRUE\n  - livenessProbe.timeoutSeconds=10\n  - metrics.annotations[0]=hey,metrics.annotations[1]=ho\n\nwhich sets the top level key mybool to true, the nested timeoutSeconds to 10, and two array values, respectively.\n\nNote that the value side of the key=val provided to '--set' and '--set-string' flags will pass through\nshell evaluation followed by yaml type parsing to produce the final value. This may alter inputs with\nspecial characters in unexpected ways, for example\n\n\t$ helm upgrade --set pwd=3jk$o2,z=f\\30.e redis .\/redis\n\nresults in \"pwd: 3jk\" and \"z: f30.e\". Use single quotes to avoid shell evaluation and argument delimiters,\nand use backslash to escape yaml special characters:\n\n\t$ helm upgrade --set pwd='3jk$o2z=f\\\\30.e' redis .\/redis\n\nwhich results in the expected \"pwd: 3jk$o2z=f\\30.e\". If a single quote occurs in your value then follow\nyour shell convention for escaping it; for example in bash:\n\n\t$ helm upgrade --set pwd='3jk$o2z=f\\\\30with'\\''quote'\n\nwhich results in \"pwd: 3jk$o2z=f\\30with'quote\".\n`\n\ntype upgradeCmd struct {\n\trelease      string\n\tchart        string\n\tout          io.Writer\n\tclient       helm.Interface\n\tdryRun       bool\n\trecreate     bool\n\tforce        bool\n\tdisableHooks bool\n\tvalueFiles   valueFiles\n\tvalues       []string\n\tstringValues []string\n\tfileValues   []string\n\tverify       bool\n\tkeyring      string\n\tinstall      bool\n\tnamespace    string\n\tversion      string\n\ttimeout      int64\n\tresetValues  bool\n\treuseValues  bool\n\twait         bool\n\tatomic       bool\n\trepoURL      string\n\tusername     string\n\tpassword     string\n\tdevel        bool\n\tsubNotes     bool\n\tdescription  string\n\n\tcertFile string\n\tkeyFile  string\n\tcaFile   string\n}\n\nfunc newUpgradeCmd(client helm.Interface, out io.Writer) *cobra.Command {\n\n\tupgrade := &upgradeCmd{\n\t\tout:    out,\n\t\tclient: client,\n\t}\n\n\tcmd := &cobra.Command{\n\t\tUse:     \"upgrade [RELEASE] [CHART]\",\n\t\tShort:   \"upgrade a release\",\n\t\tLong:    upgradeDesc,\n\t\tPreRunE: func(_ *cobra.Command, _ []string) error { return setupConnection() },\n\t\tRunE: func(cmd *cobra.Command, args []string) error {\n\t\t\tif err := checkArgsLength(len(args), \"release name\", \"chart path\"); err != nil {\n\t\t\t\treturn err\n\t\t\t}\n\n\t\t\tif upgrade.version == \"\" && upgrade.devel {\n\t\t\t\tdebug(\"setting version to >0.0.0-0\")\n\t\t\t\tupgrade.version = \">0.0.0-0\"\n\t\t\t}\n\n\t\t\tupgrade.release = args[0]\n\t\t\tupgrade.chart = args[1]\n\t\t\tupgrade.client = ensureHelmClient(upgrade.client)\n\t\t\tupgrade.wait = upgrade.wait || upgrade.atomic\n\n\t\t\treturn upgrade.run()\n\t\t},\n\t}\n\n\tf := cmd.Flags()\n\tsettings.AddFlagsTLS(f)\n\tf.VarP(&upgrade.valueFiles, \"values\", \"f\", \"specify values in a YAML file or a URL(can specify multiple)\")\n\tf.BoolVar(&upgrade.dryRun, \"dry-run\", false, \"simulate an upgrade\")\n\tf.BoolVar(&upgrade.recreate, \"recreate-pods\", false, \"performs pods restart for the resource if applicable\")\n\tf.BoolVar(&upgrade.force, \"force\", false, \"force resource update through delete\/recreate if needed\")\n\tf.StringArrayVar(&upgrade.values, \"set\", []string{}, \"set values on the command line (can specify multiple or separate values with commas: key1=val1,key2=val2)\")\n\tf.StringArrayVar(&upgrade.stringValues, \"set-string\", []string{}, \"set STRING values on the command line (can specify multiple or separate values with commas: key1=val1,key2=val2)\")\n\tf.StringArrayVar(&upgrade.fileValues, \"set-file\", []string{}, \"set values from respective files specified via the command line (can specify multiple or separate values with commas: key1=path1,key2=path2)\")\n\tf.BoolVar(&upgrade.disableHooks, \"disable-hooks\", false, \"disable pre\/post upgrade hooks.

The two most significant bits of this length byte correspond\n\/\/ to bit 5 and 4 of qcInfo (see below).  The byte sequence itself starts at v+1.\n\/\/ The byte sequence is followed by a trailing and leading CCC if the values\n\/\/ for these are not zero.  The value of v determines which ccc are appended\n\/\/ to the sequences.  For v < firstCCC, there are none, for v >= firstCCC,\n\/\/ the sequence is followed by a trailing ccc, and for v >= firstLeadingCC\n\/\/ there is an additional leading ccc. The value of tccc itself is the\n\/\/ trailing CCC shifted left 2 bits.

{"text":"<commit_before>\/*\n\n\tstatic is a library that helps automate creating the static directory of\n\tfiles for the webapp to function. It, along with lib\/build\/api, is one\n\thalf of the build process to produce a functioning webapp given a\n\tconfig.json\n\n\tAll of the steps it does could be done by hand, but they are finicky and\n\terror prone, so this library helps take the guess work out of them.\n\n\tBuild() is the primary entrypoint for this package, which composes all of\n\tthe build steps, which are themselves exposed as public methods int his\n\tpackage, in the right order.\n\n\tAll build methods in this package take a dir parameter. This is the\n\tdirectory to produce the build into. In particular, these methods will\n\tcreate a `static` subdirectory in dir and work inside of that. dir may be\n\t\"\", which will create the static sub-folder within the current directory.\n\tTools like `boardgame-util serve` create a temporary directory and use\n\tthat, so it's easy to clean up later.\n\n\tThe steps of the build process, at a high level, are as follows:\n\n\tFirst, create the `static` sub directory, if it doesn't already exist. All\n\tfollowing steps create files and directories within that static subfolder.\n\n\tNext, it copies over all of the static resources (no directories) from\n\t`github.com\/jkomoros\/boardgame\/server\/static`, skipping a handful of files\n\tthat will be generated later. These files are symlinked by default, but\n\tcan also be copied. This step is encapsulated by CopyStaticResources.\n\n\tNext, it creates a node_modules folder that contains up to date\n\tdependencies given the contents of\n\t`github.com\/jkomoros\/boardgame\/server\/static\/package.json`. Checking out\n\tthis whole directory is expensive, so this package creates a node_modules\n\tin a central cache, re-upping it each time this command is run, and then\n\tsymlinks it into the static directory. This step is encapsulated by\n\tLinkNodeModules.\n\n\tNext, it generates a `client_config.js`, which encodes the global\n\tconfiguration for the client webapp. It calls config.Client(false) and\n\tsaves the result to static\/client-config.js, which index.html will look\n\tfor when booting up. This step is encapsulated by CreateClientConfigJs.\n\n\tNext, it copies in the client folders (containing boardgame-render-game-\n\tGAMENAME.js, and optionally boardgame-render-player-info-GAMENAME.js) into\n\tstatic\/game-src. It does this by locating the on-disk location of each\n\tgameImport given by gameImports (typically this is configMode.Games), then\n\tsymlinking its client folder into `static\/game-src\/GAMENAME`. In a modules\n\tcontext, game packages that do not yet exist on disk will be downloaded\n\tautomatically; if you are not using modules and you have not yet `go get`\n\tthe given game imports or a containg package, it will error. This step is\n\tencapsulated by LinkGameClientFolders.\n\n\tNext, it generates a `static\/polymer.json`, which contains fragments\n\tentries for each dynamic import--specifically, the `game-src\/GAMENAME\n\t\/boardgame-render-game-GAMENAME.js` and `game-src\/GAMENAME\/boardgame-\n\trender-player-info-GAMENAME.js`, if it exists. It identifes the fragments\n\tto include by walking through all of the game directories in `game-src`,\n\tmeaning it relies on the output of the previous step. It then saves this\n\tgenerated file to `static\/polymer.json`. This step is encapsulated by\n\tCreatePolymerJson.\n\n\tThe static build is not mostly complete. Optionally, BuildPolymer can be\n\tcalled to run `polymer build` on the generated static dir. This step is\n\tencapsulated by BuildPolymer.\n\n\tTypically direct users of this package use Build(), which automatically\n\truns these steps in the proper order.\n\n\tTypically you don't use this package directly, but use `boardgame-util\n\tbuild static` or `boardgame-util serve`.\n\n*\/\npackage static\n\nimport (\n\t\"errors\"\n\t\"fmt\"\n\t\"github.com\/jkomoros\/boardgame\/boardgame-util\/lib\/config\"\n\t\"os\"\n\t\"os\/exec\"\n\t\"path\/filepath\"\n)\n\nvar filesToExclude map[string]bool = map[string]bool{\n\t\".gitignore\":      true,\n\t\"README.md\":       true,\n\tpolymerConfig:     true,\n\tnodeModulesFolder: true,\n\t\/\/Don't copy over because we'll generate our own; if we copy over and\n\t\/\/generate our own we'll overwrite original.\n\tclientConfigJsFileName: true,\n\t\".DS_Store\":            true,\n}\n\n\/\/Server runs a static server. directory is the folder that the `static`\n\/\/folder is contained within.

The same model abstraction and data validation is\nused for HTML forms and for databases. So a model can be loaded from a database,\ndisplayed as an HTML form and saved back to the database after submit.\nThis is not always a good practice, but it shows how easy things can be.\n\nA model is a simple Go struct that uses gostart\/model types as struct members.\nCustom model wide validation is done by adding a Validate() method to the\nstruct type:\n\n\ttype SignupFormModel struct {\n\t\tEmail     model.Email    `gostart:\"required\"`\n\t\tPassword1 model.Password `gostart:\"required|label=Password|minlen=6\"`\n\t\tPassword2 model.Password `gostart:\"label=Repeat password\"`\n\t}\n\n\tfunc (self *SignupFormModel) Validate(metaData *model.MetaData) []*model.ValidationError {\n\t\tif self.Password1 != self.Password2 {\n\t\t\treturn model.NewValidationErrors(os.NewError(\"Passwords don't match\"), metaData)\n\t\t}\n\terrors := NoValidationErrors\n\t\treturn model.NoValidationErrors\n\t}\n\n\nHere is how a HTML form is created that displays input fields for the SignupFormModel:\n\n\tform := &Form{\n\t\tButtonText: \"Signup\",\n\t\tFormID:     \"user_signup\",\n\t\tGetModel: func(form *Form, context *Context) (interface{}, error) {\n\t\t\treturn &SignupFormModel{}, nil\n\t\t},\n\t\tOnSubmit: func(form *Form, formModel interface{}, context *Context) (err error) {\n\t\t\tm := formModel.(*SignupFormModel)\n\t\t\t\/\/ ... create user in db and send confirmation email ...\n\t\t\treturn err\n\t\t},\n\t}\n\n\nMongoDB is the default database of go-start utilizing Gustavo Niemeyer's\ngreat lib mgo (http:\/\/labix.org\/mgo).\n\nMongo collections and queries are encapsulated to make them compatible with the\ngo-start data model concept, and a little bit easier to use.\n\nExample of a collection and document struct:\n\n\tvar ExampleDocs *mongo.Collection = mongo.NewCollection(\"exampledocs\", (*ExampleDoc)(nil))\n\n\ttype ExampleDoc struct {\n\t\tmongo.DocumentBase `bson:\",inline\"`                 \/\/ Give it a Mongo ID\n\t\tPerson             mongo.Ref  `gostart:\"to=people\"` \/\/ Mongo ID ref to a document in \"people\" collection\n\t\tLongerText         model.Text `gostart:\"rows=5|cols=80|maxlen=400\"`\n\t\tInteger            model.Int  `gostart:\"min=1|max=100\"`\n\t\tEmail              model.Email    \/\/ Normalization + special treament in forms\n\t\tPhoneNumber        model.Phone    \/\/ Normalization + special treament in forms\n\t\tPassword           model.Password \/\/ Hashed + special treament in forms\n\t\tSubDoc             struct {\n\t\t\tDay       model.Date\n\t\t\tDrinks    []mongo.Choice `gostart:\"options=Beer,Wine,Water\"` \/\/ Mongo array of strings\n\t\t\tRealFloat model.Float    `gostart:\"valid\" \/\/ Must be a real float value, not NaN or Inf\n\t\t}\n\t}\n\nExample query:\n\n\ti := models.Users.Filter(\"Name.Last\", \"Smith\").Sort(\"Name.First\").Iterator();\n\tfor doc := i.Next(); doc != nil; doc = i.Next() {\n\t\tuser := doc.(*models.User)\n\t\t\/\/ ...\n\t}\n\t\/\/ Err() returns any error after Next() returned nil:\n\tif i.Err() != nil {\n\t\tpanic(i.Err())\n\t}\n\nA new mongo.Document is always created by the corresponding collection object\nto initialize it with meta information about its collection.\nThis way it is possible to implement Save() or Remove() methods for the document.\n\nExample for creating, modifying and saving a document:\n\n\tuser := models.Users.NewDocument().(*models.User)\n\n\tuser.Name.First.Set(\"Erik\")\n\tuser.Name.Last.Set(\"Unger\")\n\n\terr := user.Save()\n\n\n\n*\/\npackage gostart\n\n\/\/ Include all packages for build and install\nimport (\n\t_ \"github.com\/ungerik\/go-amiando\"\n\t_ \"github.com\/ungerik\/go-gravatar\"\n\t_ \"github.com\/ungerik\/go-mail\"\n\t_ \"github.com\/ungerik\/go-rss\"\n\t_ \"github.com\/ungerik\/goconfig\"\n\t_ \"github.com\/ungerik\/mustache.go\"\n\t_ \"github.com\/ungerik\/web.go\"\n\t_ \"launchpad.net\/mgo\"\n\n\t_ \"github.com\/ungerik\/go-start\/debug\"\n\t_ \"github.com\/ungerik\/go-start\/errs\"\n\t_ \"github.com\/ungerik\/go-start\/i18n\"\n\t_ \"github.com\/ungerik\/go-start\/media\"\n\t_ \"github.com\/ungerik\/go-start\/model\"\n\t_ \"github.com\/ungerik\/go-start\/modelext\"\n\t_ \"github.com\/ungerik\/go-start\/mongo\"\n\t_ \"github.com\/ungerik\/go-start\/mongomedia\"\n\t_ \"github.com\/ungerik\/go-start\/templatesystem\"\n\t_ \"github.com\/ungerik\/go-start\/user\"\n\t_ \"github.com\/ungerik\/go-start\/utils\"\n\t_ \"github.com\/ungerik\/go-start\/view\"\n)\n<commit_msg>doc update<commit_after>\/*\ngo-start is a high level web-framework for Go,\nlike Django for Python or Rails for Ruby.\n\nSource: https:\/\/github.com\/ungerik\/go-start\/\n\nDocumentation: http:\/\/go-start.org\/pkg\/go-start\/gostart\/\n\nNote: Don't use Go on 32 bit systems in production, it has severe memory leaks.\n(If the documentation URL above doesn't work, then godoc -html has has crashed because of that issue)\n\n## Intro:\n\nFeatures:\n\n* HTML views can be defined in Go syntax\n* Optional template system\n* HTML5 Boilerplate page template (Mustache template, will be changed to Go v1 template)\n* Unified data model for forms and databases\n* Data models are simple Go structs\n* MongoDB as default database\n* User management\/authentication out of the box\n* Additional packages for\n\t* Email (Google Mail defaults): http:\/\/github.com\/ungerik\/go-mail\n\t* Gravatar: http:\/\/github.com\/ungerik\/go-gravatar\n\t* RSS parsing: http:\/\/github.com\/ungerik\/go-rss\n\t* Amiando event management: http:\/\/github.com\/ungerik\/go-amiando\n\t\t(used by http:\/\/startuplive.in)\n\n\n## Views:\n\nThe philosophy for creating HTML views is (unlike Rails\/Django) that you should\nnot have to learn yet another language to be able to write templates.\nThere are several very simple template languages out there that reduce program\ncode like logic within the template, but it’s still yet another syntax to learn.\n\nIn go-start the HTML structure of a page is represented by a structure of\ntype safe Go objects.\nIt should feel like writing HTML but using the syntax of Go.\nAnd no, it has nothing to do with the mess of intertwined markup and code in PHP.\n\nExample of a static view:\n\n\tview := Views{\n\t\tDIV(\"myclass\",\n\t\t\tH1(\"Example HTML structure\"),\n\t\t\tP(\"This is a paragraph\"),\n\t\t\tP(\n\t\t\t\tHTML(\"Some unescaped HTML:<br\/>\"),\n\t\t\t\tPrintf(\"The number of the beast: %d\", 666),\n\t\t\t\tEscape(\"Will be escaped: 666 < 999\"),\n\t\t\t),\n\t\t\tA_blank(\"http:\/\/go-lang.org\", \"A very simple link\"),\n\t\t),\n\t\tHR(),\n\t\tPRE(\"\t<- pre formated text, followed by a list:\"),\n\t\tUL(\"red\", \"green\", \"blue\"),\n\t\t&Template{\n\t\t\tFilename: \"mytemplate.html\",\n\t\t\tGetContext: func(requestContext *Context) (interface{}, error) {\n\t\t\t\treturn map[string]string{\"Key\": \"Value\"}, nil\n\t\t\t},\n\t\t},\n\t}\n\nExample of a dynamic view:\n\n\tview := DynamicView(\n\t\tfunc(context *Context) (view View, err error) {\n\t\t\tvar names []string\n\t\t\ti := models.Users.Sort(\"Name.First\").Sort(\"Name.Last\").Iterator();\n\t\t\tfor doc := i.Next();

So a model can be loaded from a database,\ndisplayed as an HTML form and saved back to the database after submit.\nThis is not always a good practice, but it shows how easy things can be.\n\nA model is a simple Go struct that uses gostart\/model types as struct members.\nCustom model wide validation is done by adding a Validate() method to the\nstruct type:\n\n\ttype SignupFormModel struct {\n\t\tEmail     model.Email    `gostart:\"required\"`\n\t\tPassword1 model.Password `gostart:\"required|label=Password|minlen=6\"`\n\t\tPassword2 model.Password `gostart:\"label=Repeat password\"`\n\t}\n\n\tfunc (self *SignupFormModel) Validate(metaData *model.MetaData) []*model.ValidationError {\n\t\tif self.Password1 != self.Password2 {\n\t\t\treturn model.NewValidationErrors(os.NewError(\"Passwords don't match\"), metaData)\n\t\t}\n\terrors := NoValidationErrors\n\t\treturn model.NoValidationErrors\n\t}\n\n\nHere is how a HTML form is created that displays input fields for the SignupFormModel:\n\n\tform := &Form{\n\t\tButtonText: \"Signup\",\n\t\tFormID:     \"user_signup\",\n\t\tGetModel: func(form *Form, context *Context) (interface{}, error) {\n\t\t\treturn &SignupFormModel{}, nil\n\t\t},\n\t\tOnSubmit: func(form *Form, formModel interface{}, context *Context) (err error) {\n\t\t\tm := formModel.(*SignupFormModel)\n\t\t\t\/\/ ... create user in db and send confirmation email ...\n\t\t\treturn err\n\t\t},\n\t}\n\n\nMongoDB is the default database of go-start utilizing Gustavo Niemeyer's\ngreat lib mgo (http:\/\/labix.org\/mgo).\n\nMongo collections and queries are encapsulated to make them compatible with the\ngo-start data model concept, and a little bit easier to use.\n\nExample of a collection and document struct:\n\n\tvar ExampleDocs *mongo.Collection = mongo.NewCollection(\"exampledocs\", (*ExampleDoc)(nil))\n\n\ttype ExampleDoc struct {\n\t\tmongo.DocumentBase `bson:\",inline\"`                 \/\/ Give it a Mongo ID\n\t\tPerson             mongo.Ref  `gostart:\"to=people\"` \/\/ Mongo ID ref to a document in \"people\" collection\n\t\tLongerText         model.Text `gostart:\"rows=5|cols=80|maxlen=400\"`\n\t\tInteger            model.Int  `gostart:\"min=1|max=100\"`\n\t\tEmail              model.Email    \/\/ Normalization + special treament in forms\n\t\tPhoneNumber        model.Phone    \/\/ Normalization + special treament in forms\n\t\tPassword           model.Password \/\/ Hashed + special treament in forms\n\t\tSubDoc             struct {\n\t\t\tDay       model.Date\n\t\t\tDrinks    []mongo.Choice `gostart:\"options=Beer,Wine,Water\"` \/\/ Mongo array of strings\n\t\t\tRealFloat model.Float    `gostart:\"valid\" \/\/ Must be a real float value, not NaN or Inf\n\t\t}\n\t}\n\nExample query:\n\n\ti := models.Users.Filter(\"Name.Last\", \"Smith\").Sort(\"Name.First\").Iterator();\n\tfor doc := i.Next(); doc != nil; doc = i.Next() {\n\t\tuser := doc.(*models.User)\n\t\t\/\/ ...\n\t}\n\t\/\/ Err() returns any error after Next() returned nil:\n\tif i.Err() != nil {\n\t\tpanic(i.Err())\n\t}\n\nA new mongo.Document is always created by the corresponding collection object\nto initialize it with meta information about its collection.\nThis way it is possible to implement Save() or Remove() methods for the document.\n\nExample for creating, modifying and saving a document:\n\n\tuser := models.Users.NewDocument().(*models.User)\n\n\tuser.Name.First.Set(\"Erik\")\n\tuser.Name.Last.Set(\"Unger\")\n\n\terr := user.Save()\n\n\n\n*\/\npackage gostart\n\n\/\/ Include all packages for build and install\nimport (\n\t_ \"github.com\/ungerik\/go-amiando\"\n\t_ \"github.com\/ungerik\/go-gravatar\"\n\t_ \"github.com\/ungerik\/go-mail\"\n\t_ \"github.com\/ungerik\/go-rss\"\n\t_ \"github.com\/ungerik\/goconfig\"\n\t_ \"github.com\/ungerik\/mustache.go\"\n\t_ \"github.com\/ungerik\/web.go\"\n\t_ \"launchpad.net\/mgo\"\n\n\t_ \"github.com\/ungerik\/go-start\/debug\"\n\t_ \"github.com\/ungerik\/go-start\/errs\"\n\t_ \"github.com\/ungerik\/go-start\/i18n\"\n\t_ \"github.com\/ungerik\/go-start\/media\"\n\t_ \"github.com\/ungerik\/go-start\/model\"\n\t_ \"github.com\/ungerik\/go-start\/modelext\"\n\t_ \"github.com\/ungerik\/go-start\/mongo\"\n\t_ \"github.com\/ungerik\/go-start\/mongomedia\"\n\t_ \"github.com\/ungerik\/go-start\/templatesystem\"\n\t_ \"github.com\/ungerik\/go-start\/user\"\n\t_ \"github.com\/ungerik\/go-start\/utils\"\n\t_ \"github.com\/ungerik\/go-start\/view\"\n)\n<|endoftext|>"}

connect to it: one input channel stays for the entire session lifetime. the ws is only stored in the connection context (Session#Handle), as is the closing channel. added an atomic counter that stops the server from throwing out sessions just because ONE of the connections disconnected. added a log message for when the server fails to listen. NOTE: there is still no SUPPORT for multiple sockets to the same session, just a sort of graceful error state (the connections will likely share the messages among themselves).<commit_after>package

{"text":"<commit_before>\/\/ update_go_deps modifies the go.mod and go.sum files to sync to the most\n\/\/ recent versions of all listed dependencies.\n\/\/\n\/\/ If the go.mod file is not being updated, check the recent runs of this Task\n\/\/ Driver to verify that:\n\/\/\n\/\/ 1. It is running at all. If not, there may be a bot capacity problem, or a\n\/\/    problem with the Task Scheduler.\n\/\/ 2. It is succeeding. There are a number of reasons why it might fail, but the\n\/\/    most common is that a change has landed in one of the dependencies which\n\/\/    is not compatible with the current version of our code. Check the logs for\n\/\/    the failing step(s).\n\/\/ 3. The CL uploaded by this task driver is passing the commit queue and\n\/\/    landing. This task driver does not run all of the tests and so the CL it\n\/\/    uploads may fail the commit queue for legitimate reasons. Look into the\n\/\/    failures and determine what actions to take.\n\/\/\n\/\/ If update_go_deps itself is failing, or if the CL it uploads is failing to\n\/\/ land, you may need to take one of the following actions:\n\/\/\n\/\/ 1. If possible, update call sites in our repo(s) to match the upstream\n\/\/    changes. Include the update to go.mod in the same CL. This is only\n\/\/    possible if our repo is the only user of the modified dependency, or if\n\/\/    all other users have already updated to account for the change.\n\/\/ 2. Add an \"exclude\" directive in go.mod. Ideally, this is temporary and can\n\/\/    be removed, eg. when all of our dependencies have updated to account for\n\/\/    a breaking change in a shared dependency. If you expect the exclude to be\n\/\/    temporary, file a bug and add a comment next to the exclude. Note that\n\/\/    only specific versions can be excluded, so we may need to exclude\n\/\/    additional versions for the same breaking change as versions are released.\n\/\/ 3. If the breaking change is intentional and we never expect to be able to\n\/\/    update to a newer version of the dependency (eg. a required feature was\n\/\/    removed), fork the broken dependency. Update all references in our repo(s)\n\/\/    to use the fork, or add a \"replace\" directive in go.mod. Generally we\n\/\/    should file a bug against the dependency first to verify that the breaking\n\/\/    change is both intentional and not going to be reversed.

It is running at all. If not, there may be a bot capacity problem, or a\n\/\/    problem with the Task Scheduler.\n\/\/ 2. It is succeeding. There are a number of reasons why it might fail, but the\n\/\/    most common is that a change has landed in one of the dependencies which\n\/\/    is not compatible with the current version of our code. Check the logs for\n\/\/    the failing step(s).\n\/\/ 3. The CL uploaded by this task driver is passing the commit queue and\n\/\/    landing. This task driver does not run all of the tests and so the CL it\n\/\/    uploads may fail the commit queue for legitimate reasons. Look into the\n\/\/    failures and determine what actions to take.\n\/\/\n\/\/ If update_go_deps itself is failing, or if the CL it uploads is failing to\n\/\/ land, you may need to take one of the following actions:\n\/\/\n\/\/ 1. If possible, update call sites in our repo(s) to match the upstream\n\/\/    changes. Include the update to go.mod in the same CL. This is only\n\/\/    possible if our repo is the only user of the modified dependency, or if\n\/\/    all other users have already updated to account for the change.\n\/\/ 2. Add an \"exclude\" directive in go.mod. Ideally, this is temporary and can\n\/\/    be removed, eg. when all of our dependencies have updated to account for\n\/\/    a breaking change in a shared dependency. If you expect the exclude to be\n\/\/    temporary, file a bug and add a comment next to the exclude. Note that\n\/\/    only specific versions can be excluded, so we may need to exclude\n\/\/    additional versions for the same breaking change as versions are released.\n\/\/ 3. If the breaking change is intentional and we never expect to be able to\n\/\/    update to a newer version of the dependency (eg. a required feature was\n\/\/    removed), fork the broken dependency. Update all references in our repo(s)\n\/\/    to use the fork, or add a \"replace\" directive in go.mod. Generally we\n\/\/    should file a bug against the dependency first to verify that the breaking\n\/\/    change is both intentional and not going to be reversed. Forking implies\n\/\/    some amount of maintenance headache (eg. what if the dependency is shared\n\/\/    by others which assume they're using the most recent version?), so this\n\/\/    should be a last resort.\npackage main\n\nimport (\n\t\"bytes\"\n\t\"context\"\n\t\"flag\"\n\t\"fmt\"\n\t\"path\"\n\t\"path\/filepath\"\n\t\"strconv\"\n\t\"strings\"\n\n\t\"go.skia.org\/infra\/go\/auth\"\n\t\"go.skia.org\/infra\/go\/common\"\n\t\"go.skia.org\/infra\/go\/exec\"\n\t\"go.skia.org\/infra\/go\/util\"\n\t\"go.skia.org\/infra\/task_driver\/go\/lib\/auth_steps\"\n\t\"go.skia.org\/infra\/task_driver\/go\/lib\/checkout\"\n\t\"go.skia.org\/infra\/task_driver\/go\/lib\/gerrit_steps\"\n\t\"go.skia.org\/infra\/task_driver\/go\/lib\/golang\"\n\t\"go.skia.org\/infra\/task_driver\/go\/lib\/os_steps\"\n\t\"go.skia.org\/infra\/task_driver\/go\/lib\/rotations\"\n\t\"go.skia.org\/infra\/task_driver\/go\/td\"\n)\n\nvar (\n\t\/\/ Required properties for this task.\n\tgerritProject = flag.String(\"gerrit_project\", \"\", \"Gerrit project name.\")\n\tgerritUrl     = flag.String(\"gerrit_url\", \"\", \"URL of the Gerrit server.\")\n\tprojectId     = flag.String(\"project_id\", \"\", \"ID of the Google Cloud project.\")\n\ttaskId        = flag.String(\"task_id\", \"\", \"ID of this task.\")\n\ttaskName      = flag.String(\"task_name\", \"\", \"Name of the task.\")\n\tworkdir       = flag.String(\"workdir\", \".\", \"Working directory\")\n\n\tcheckoutFlags = checkout.SetupFlags(nil)\n\n\t\/\/ Optional flags.\n\tlocal  = flag.Bool(\"local\", false, \"True if running locally (as opposed to on the bots)\")\n\toutput = flag.String(\"o\", \"\", \"If provided, dump a JSON blob of step data to the given file.

All rights reserved.\n\/\/ Use of this source code is governed by a BSD-style\n\/\/ license that can be found in the LICENSE file.\n\n\/*\nPackage packages loads Go packages for inspection and analysis.\n\nNOTE: THIS PACKAGE IS NOT YET READY FOR WIDESPREAD USE:\n - The interface is still being revised and minor changes are likely.\n - The implementation depends on the Go 1.11 go command;\n   support for earlier versions will be added soon.\n - We intend to finalize the API before Go 1.11 is released.\n\nThe Load function takes as input a list of patterns and return a list of Package\nstructs describing individual packages matched by those patterns.\nThe LoadMode controls the amount of detail in the loaded packages.\n\nLoad passes most patterns directly to the underlying build tool,\nbut all patterns with the prefix \"query=\", where query is a\nnon-empty string of letters from [a-z], are reserved and may be\ninterpreted as query operators.\n\nOnly two query operators are currently supported, \"file\" and \"pattern\".\n\nThe query \"file=path\/to\/file.go\" matches the package or packages enclosing\nthe Go source file path\/to\/file.go.  For example \"file=~\/go\/src\/fmt\/print.go\"\nmight returns the packages \"fmt\" and \"fmt [fmt.test]\".\n\nThe query \"pattern=string\" causes \"string\" to be passed directly to\nthe underlying build tool. In most cases this is unnecessary,\nbut an application can use Load(\"pattern=\" + x) as an escaping mechanism\nto ensure that x is not interpreted as a query operator if it contains '='.\n\nA third query \"name=identifier\" will be added soon.\nIt will match packages whose package declaration contains the specified identifier.\nFor example, \"name=rand\" would match the packages \"math\/rand\" and \"crypto\/rand\",\nand \"name=main\" would match all executables.\n\nAll other query operators are reserved for future use and currently\ncause Load to report an error.\n\nThe Package struct provides basic information about the package, including\n\n  - ID, a unique identifier for the package in the returned set;\n  - GoFiles, the names of the package's Go source files;\n  - Imports, a map from source import strings to the Packages they name;\n  - Types, the type information for the package's exported symbols;\n  - Syntax, the parsed syntax trees for the package's source code; and\n  - TypeInfo, the result of a complete type-check of the package syntax trees.\n\n(See the documentation for type Package for the complete list of fields\nand more detailed descriptions.)\n\nFor example,\n\n\tLoad(nil, \"bytes\", \"unicode...\")\n\nreturns four Package structs describing the standard library packages\nbytes, unicode, unicode\/utf16, and unicode\/utf8. Note that one pattern\ncan match multiple packages and that a package might be matched by\nmultiple patterns: in general it is not possible to determine which\npackages correspond to which patterns.\n\nNote that the list returned by Load contains only the packages matched\nby the patterns. Their dependencies can be found by walking the import\ngraph using the Imports fields.\n\nThe Load function can be configured by passing a pointer to a Config as\nthe first argument. A nil Config is equivalent to the zero Config, which\ncauses Load to run in LoadFiles mode, collecting minimal information.\nSee the documentation for type Config for details.\n\nAs noted earlier, the Config.Mode controls the amount of detail\nreported about the loaded packages, with each mode returning all the data of the\nprevious mode with some extra added. See the documentation for type LoadMode\nfor details.\n\nMost tools should pass their command-line arguments (after any flags)\nuninterpreted to the loader, so that the loader can interpret them\naccording to the conventions of the underlying build system.\nSee the Example function for typical usage.\n\n*\/\npackage packages \/\/ import \"golang.org\/x\/tools\/go\/packages\"\n\n\/*\n\nMotivation and design considerations\n\nThe new package's design solves problems addressed by two existing\npackages: go\/build, which locates and describes packages, and\ngolang.org\/x\/tools\/go\/loader, which loads, parses and type-checks them.\nThe go\/build.Package structure encodes too much of the 'go build' way\nof organizing projects, leaving us in need of a data type that describes a\npackage of Go source code independent of the underlying build system.\nWe wanted something that works equally well with go build and vgo, and\nalso other build systems such as Bazel and Blaze, making it possible to\nconstruct analysis tools that work in all these environments.\nTools such as errcheck and staticcheck were essentially unavailable to\nthe Go community at Google, and some of Google's internal tools for Go\nare unavailable externally.\nThis new package provides a uniform way to obtain package metadata by\nquerying each of these build systems, optionally supporting their\npreferred command-line notations for packages, so that tools integrate\nneatly with users' build environments. The Metadata query function\nexecutes an external query tool appropriate to the current workspace.\n\nLoading packages always returns the complete import graph \"all the way down\",\neven if all you want is information about a single package, because the query\nmechanisms of all the build systems we currently support ({go,vgo} list, and\nblaze\/bazel aspect-based query) cannot provide detailed information\nabout one package without visiting all its dependencies too, so there is\nno additional asymptotic cost to providing transitive information.\n(This property might not be true of a hypothetical 5th build system.)\n\nIn calls to TypeCheck, all initial packages, and any package that\ntransitively depends on one of them, must be loaded from source.\nConsider A->B->C->D->E: if A,C are initial, A,B,C must be loaded from\nsource; D may be loaded from export data, and E may not be loaded at all\n(though it's possible that D's export data mentions it, so a\ntypes.Package may be created for it and exposed.)\n\nThe old loader had a feature to suppress type-checking of function\nbodies on a per-package basis, primarily intended to reduce the work of\nobtaining type information for imported packages. Now that imports are\nsatisfied by export data, the optimization no longer seems necessary.\n\nDespite some early attempts, the old loader did not exploit export data,\ninstead always using the equivalent of WholeProgram mode. This was due\nto the complexity of mixing source and export data packages (now\nresolved by the upward traversal mentioned above), and because export data\nfiles were nearly always missing or stale. Now that 'go build' supports\ncaching, all the underlying build systems can guarantee to produce\nexport data in a reasonable (amortized) time.\n\nTest \"main\" packages synthesized by the build system are now reported as\nfirst-class packages, avoiding the need for clients (such as go\/ssa) to\nreinvent this generation logic.\n\nOne way in which go\/packages is simpler than the old loader is in its\ntreatment of in-package tests. In-package tests are packages that\nconsist of all the files of the library under test, plus the test files.\nThe old loader constructed in-package tests by a two-phase process of\nmutation called \"augmentation\": first it would construct and type check\nall the ordinary library packages and type-check the packages that\ndepend on them; then it would add more (test) files to the package and\ntype-check again. This two-phase approach had four major problems:\n1) in processing the tests, the loader modified the library package,\n   leaving no way for a client application to see both the test\n   package and the library package; one would mutate into the other.\n2) because test files can declare additional methods on types defined in\n   the library portion of the package, the dispatch of method calls in\n   the library portion was affected by the presence of the test files.\n   This should have been a clue that the packages were logically\n   different.\n3) this model of \"augmentation\" assumed at most one in-package test\n   per library package, which is true of projects using 'go build',\n   but not other build systems.\n4) because of the two-phase nature of test processing, all packages that\n   import the library package had to be processed before augmentation,\n   forcing a \"one-shot\" API and preventing the client from calling Load\n   in several times in sequence as is now possible in WholeProgram mode.\n   (TypeCheck mode has a similar one-shot restriction for a different reason.)\n\nEarly drafts of this package supported \"multi-shot\" operation.\nAlthough it allowed clients to make a sequence of calls (or concurrent\ncalls) to Load, building up the graph of Packages incrementally,\nit was of marginal value: it complicated the API\n(since it allowed some options to vary across calls but not others),\nit complicated the implementation,\nit cannot be made to work in Types mode, as explained above,\nand it was less efficient than making one combined call (when this is possible).\nAmong the clients we have inspected, none made multiple calls to load\nbut could not be easily and satisfactorily modified to make only a single call.\nHowever, applications changes may be required.\nFor example, the ssadump command loads the user-specified packages\nand in addition the runtime package.  It is tempting to simply append\n\"runtime\" to the user-provided list, but that does not work if the user\nspecified an ad-hoc package such as [a.go b.go].\nInstead, ssadump no longer requests the runtime package,\nbut seeks it among the dependencies of the user-specified packages,\nand emits an error if it is not found.\n\nOverlays: the ParseFile hook in the API permits clients to vary the way\nin which ASTs are obtained from filenames; the default implementation is\nbased on parser.ParseFile. This features enables editor-integrated tools\nthat analyze the contents of modified but unsaved buffers: rather than\nread from the file system, a tool can read from an archive of modified\nbuffers provided by the editor.\nThis approach has its limits. Because package metadata is obtained by\nfork\/execing an external query command for each build system, we can\nfake only the file contents seen by the parser, type-checker, and\napplication, but not by the metadata query, so, for example:\n- additional imports in the fake file will not be described by the\n  metadata, so the type checker will fail to load imports that create\n  new dependencies.\n- in TypeCheck mode, because export data is produced by the query\n  command, it will not reflect the fake file contents.\n- this mechanism cannot add files to a package without first saving them.\n\nQuestions & Tasks\n\n- Add GOARCH\/GOOS?\n  They are not portable concepts, but could be made portable.\n  Our goal has been to allow users to express themselves using the conventions\n  of the underlying build system: if the build system honors GOARCH\n  during a build and during a metadata query, then so should\n  applications built atop that query mechanism.\n  Conversely, if the target architecture of the build is determined by\n  command-line flags, the application can pass the relevant\n  flags through to the build system using a command such as:\n    myapp -query_flag=\"--cpu=amd64\" -query_flag=\"--os=darwin\"\n  However, this approach is low-level, unwieldy, and non-portable.\n  GOOS and GOARCH seem important enough to warrant a dedicated option.\n\n- How should we handle partial failures such as a mixture of good and\n  malformed patterns, existing and non-existent packages, successful and\n  failed builds, import failures, import cycles, and so on, in a call to\n  Load?\n\n- Support bazel, blaze, and go1.10 list, not just go1.11 list.\n\n- Handle (and test) various partial success cases, e.g.\n  a mixture of good packages and:\n  invalid patterns\n  nonexistent packages\n  empty packages\n  packages with malformed package or import declarations\n  unreadable files\n  import cycles\n  other parse errors\n  type errors\n  Make sure we record errors at the correct place in the graph.\n\n- Missing packages among initial arguments are not reported.\n  Return bogus packages for them, like golist does.\n\n- \"undeclared name\" errors (for example) are reported out of source file\n  order.

Any such change will be\nannounced on golang-tools@ at least one week before it is committed. No\nmore breaking changes will be made after December 1, 2018.\n\nThe Load function takes as input a list of patterns and return a list of Package\nstructs describing individual packages matched by those patterns.\nThe LoadMode controls the amount of detail in the loaded packages.\n\nLoad passes most patterns directly to the underlying build tool,\nbut all patterns with the prefix \"query=\", where query is a\nnon-empty string of letters from [a-z], are reserved and may be\ninterpreted as query operators.\n\nOnly two query operators are currently supported, \"file\" and \"pattern\".\n\nThe query \"file=path\/to\/file.go\" matches the package or packages enclosing\nthe Go source file path\/to\/file.go.  For example \"file=~\/go\/src\/fmt\/print.go\"\nmight returns the packages \"fmt\" and \"fmt [fmt.test]\".\n\nThe query \"pattern=string\" causes \"string\" to be passed directly to\nthe underlying build tool. In most cases this is unnecessary,\nbut an application can use Load(\"pattern=\" + x) as an escaping mechanism\nto ensure that x is not interpreted as a query operator if it contains '='.\n\nA third query \"name=identifier\" will be added soon.\nIt will match packages whose package declaration contains the specified identifier.\nFor example, \"name=rand\" would match the packages \"math\/rand\" and \"crypto\/rand\",\nand \"name=main\" would match all executables.\n\nAll other query operators are reserved for future use and currently\ncause Load to report an error.\n\nThe Package struct provides basic information about the package, including\n\n  - ID, a unique identifier for the package in the returned set;\n  - GoFiles, the names of the package's Go source files;\n  - Imports, a map from source import strings to the Packages they name;\n  - Types, the type information for the package's exported symbols;\n  - Syntax, the parsed syntax trees for the package's source code; and\n  - TypeInfo, the result of a complete type-check of the package syntax trees.\n\n(See the documentation for type Package for the complete list of fields\nand more detailed descriptions.)\n\nFor example,\n\n\tLoad(nil, \"bytes\", \"unicode...\")\n\nreturns four Package structs describing the standard library packages\nbytes, unicode, unicode\/utf16, and unicode\/utf8. Note that one pattern\ncan match multiple packages and that a package might be matched by\nmultiple patterns: in general it is not possible to determine which\npackages correspond to which patterns.\n\nNote that the list returned by Load contains only the packages matched\nby the patterns. Their dependencies can be found by walking the import\ngraph using the Imports fields.\n\nThe Load function can be configured by passing a pointer to a Config as\nthe first argument. A nil Config is equivalent to the zero Config, which\ncauses Load to run in LoadFiles mode, collecting minimal information.\nSee the documentation for type Config for details.\n\nAs noted earlier, the Config.Mode controls the amount of detail\nreported about the loaded packages, with each mode returning all the data of the\nprevious mode with some extra added. See the documentation for type LoadMode\nfor details.\n\nMost tools should pass their command-line arguments (after any flags)\nuninterpreted to the loader, so that the loader can interpret them\naccording to the conventions of the underlying build system.\nSee the Example function for typical usage.\n\n*\/\npackage packages \/\/ import \"golang.org\/x\/tools\/go\/packages\"\n\n\/*\n\nMotivation and design considerations\n\nThe new package's design solves problems addressed by two existing\npackages: go\/build, which locates and describes packages, and\ngolang.org\/x\/tools\/go\/loader, which loads, parses and type-checks them.\nThe go\/build.Package structure encodes too much of the 'go build' way\nof organizing projects, leaving us in need of a data type that describes a\npackage of Go source code independent of the underlying build system.\nWe wanted something that works equally well with go build and vgo, and\nalso other build systems such as Bazel and Blaze, making it possible to\nconstruct analysis tools that work in all these environments.\nTools such as errcheck and staticcheck were essentially unavailable to\nthe Go community at Google, and some of Google's internal tools for Go\nare unavailable externally.\nThis new package provides a uniform way to obtain package metadata by\nquerying each of these build systems, optionally supporting their\npreferred command-line notations for packages, so that tools integrate\nneatly with users' build environments. The Metadata query function\nexecutes an external query tool appropriate to the current workspace.\n\nLoading packages always returns the complete import graph \"all the way down\",\neven if all you want is information about a single package, because the query\nmechanisms of all the build systems we currently support ({go,vgo} list, and\nblaze\/bazel aspect-based query) cannot provide detailed information\nabout one package without visiting all its dependencies too, so there is\nno additional asymptotic cost to providing transitive information.\n(This property might not be true of a hypothetical 5th build system.)\n\nIn calls to TypeCheck, all initial packages, and any package that\ntransitively depends on one of them, must be loaded from source.\nConsider A->B->C->D->E: if A,C are initial, A,B,C must be loaded from\nsource; D may be loaded from export data, and E may not be loaded at all\n(though it's possible that D's export data mentions it, so a\ntypes.Package may be created for it and exposed.)\n\nThe old loader had a feature to suppress type-checking of function\nbodies on a per-package basis, primarily intended to reduce the work of\nobtaining type information for imported packages. Now that imports are\nsatisfied by export data, the optimization no longer seems necessary.\n\nDespite some early attempts, the old loader did not exploit export data,\ninstead always using the equivalent of WholeProgram mode. This was due\nto the complexity of mixing source and export data packages (now\nresolved by the upward traversal mentioned above), and because export data\nfiles were nearly always missing or stale. Now that 'go build' supports\ncaching, all the underlying build systems can guarantee to produce\nexport data in a reasonable (amortized) time.\n\nTest \"main\" packages synthesized by the build system are now reported as\nfirst-class packages, avoiding the need for clients (such as go\/ssa) to\nreinvent this generation logic.\n\nOne way in which go\/packages is simpler than the old loader is in its\ntreatment of in-package tests.

We create a route for that host, then add a\n\"subrouter\" to that route:\n\n\tsubrouter := mux.Host(\"www.domain.com\").NewRouter()\n\nThen register routes for the host subrouter:\n\n\tsubrouter.HandleFunc(\"\/products\/\", ProductsHandler)\n\tsubrouter.HandleFunc(\"\/products\/{key}\", ProductHandler)\n\tsubrouter.HandleFunc(\"\/articles\/{category}\/{id:[0-9]+}\"), ArticleHandler)\n\nThe three URL paths we registered above will only be tested if the domain is\n\"www.domain.com\", because the subrouter is tested first.

It is organized as a\n\/\/ collection of edges that optionally defines an interior. All geometry\n\/\/ represented by a given Shape must have the same dimension, which means that\n\/\/ an Shape can represent either a set of points, a set of polylines, or a set\n\/\/ of polygons.\n\/\/\n\/\/ Shape is defined as an interface in order to give clients control over the\n\/\/ underlying data representation. Sometimes an Shape does not have any data of\n\/\/ its own, but instead wraps some other type.\n\/\/\n\/\/ Shape operations are typically defined on a ShapeIndex rather than\n\/\/ individual shapes. An ShapeIndex is simply a collection of Shapes,\n\/\/ possibly of different dimensions (e.g. 10 points and 3 polygons), organized\n\/\/ into a data structure for efficient edge access.\n\/\/\n\/\/ The edges of a Shape are indexed by a contiguous range of edge IDs\n\/\/ starting at 0. The edges are further subdivided into chains, where each\n\/\/ chain consists of a sequence of edges connected end-to-end (a polyline).\n\/\/ For example, a Shape representing two polylines AB and CDE would have\n\/\/ three edges (AB, CD, DE) grouped into two chains: (AB) and (CD, DE).\n\/\/ Similarly, an Shape representing 5 points would have 5 chains consisting\n\/\/ of one edge each.\n\/\/\n\/\/ Shape has methods that allow edges to be accessed either using the global\n\/\/ numbering (edge ID) or within a particular chain. The global numbering is\n\/\/ sufficient for most purposes, but the chain representation is useful for\n\/\/ certain algorithms such as intersection (see BooleanOperation).\ntype Shape interface {\n\t\/\/ NumEdges returns the number of edges in this shape.\n\tNumEdges() int\n\n\t\/\/ Edge returns the edge for the given edge index.\n\tEdge(i int) Edge\n\n\t\/\/ HasInterior reports whether this shape has an interior.\n\tHasInterior() bool\n\n\t\/\/ ReferencePoint returns an arbitrary reference point for the shape. (The\n\t\/\/ containment boolean value must be false for shapes that do not have an interior.)\n\t\/\/\n\t\/\/ This reference point may then be used to compute the containment of other\n\t\/\/ points by counting edge crossings.\n\tReferencePoint() ReferencePoint\n\n\t\/\/ NumChains reports the number of contiguous edge chains in the shape.\n\t\/\/ For example, a shape whose edges are [AB, BC, CD, AE, EF] would consist\n\t\/\/ of two chains (AB,BC,CD and AE,EF). Every chain is assigned a chain Id\n\t\/\/ numbered sequentially starting from zero.\n\t\/\/\n\t\/\/ Note that it is always acceptable to implement this method by returning\n\t\/\/ NumEdges, i.e. every chain consists of a single edge, but this may\n\t\/\/ reduce the efficiency of some algorithms.\n\tNumChains() int\n\n\t\/\/ Chain returns the range of edge IDs corresponding to the given edge chain.\n\t\/\/ Edge chains must form contiguous, non-overlapping ranges that cover\n\t\/\/ the entire range of edge IDs. This is spelled out more formally below:\n\t\/\/\n\t\/\/  0 <= i < NumChains()\n\t\/\/  Chain(i).length > 0, for all i\n\t\/\/  Chain(0).start == 0\n\t\/\/  Chain(i).start + Chain(i).length == Chain(i+1).start, for i < NumChains()-1\n\t\/\/  Chain(i).start + Chain(i).length == NumEdges(), for i == NumChains()-1\n\tChain(chainID int) Chain\n\n\t\/\/ ChainEdgeReturns the edge at offset \"offset\" within edge chain \"chainID\".\n\t\/\/ Equivalent to \"shape.Edge(shape.Chain(chainID).start + offset)\"\n\t\/\/ but more efficient.\n\tChainEdge(chainID, offset int) Edge\n\n\t\/\/ ChainPosition finds the chain containing the given edge, and returns the\n\t\/\/ position of that edge as a ChainPosition(chainID, offset) pair.\n\t\/\/\n\t\/\/  shape.Chain(pos.chainID).start + pos.offset == edgeID\n\t\/\/  shape.Chain(pos.chainID+1).start > edgeID\n\t\/\/\n\t\/\/ where pos == shape.ChainPosition(edgeID).\n\tChainPosition(edgeID int) ChainPosition\n\n\t\/\/ dimension returns the dimension of the geometry represented by this shape.\n\t\/\/\n\t\/\/  pointGeometry: Each point is represented as a degenerate edge.\n\t\/\/\n\t\/\/  polylineGeometry:  Polyline edges may be degenerate. A shape may\n\t\/\/      represent any number of polylines. Polylines edges may intersect.\n\t\/\/\n\t\/\/  polygonGeometry:  Edges should be oriented such that the polygon\n\t\/\/      interior is always on the left.

It is organized as a\n\/\/ collection of edges that optionally defines an interior. All geometry\n\/\/ represented by a given Shape must have the same dimension, which means that\n\/\/ an Shape can represent either a set of points, a set of polylines, or a set\n\/\/ of polygons.\n\/\/\n\/\/ Shape is defined as an interface in order to give clients control over the\n\/\/ underlying data representation. Sometimes an Shape does not have any data of\n\/\/ its own, but instead wraps some other type.\n\/\/\n\/\/ Shape operations are typically defined on a ShapeIndex rather than\n\/\/ individual shapes. An ShapeIndex is simply a collection of Shapes,\n\/\/ possibly of different dimensions (e.g. 10 points and 3 polygons), organized\n\/\/ into a data structure for efficient edge access.\n\/\/\n\/\/ The edges of a Shape are indexed by a contiguous range of edge IDs\n\/\/ starting at 0. The edges are further subdivided into chains, where each\n\/\/ chain consists of a sequence of edges connected end-to-end (a polyline).\n\/\/ For example, a Shape representing two polylines AB and CDE would have\n\/\/ three edges (AB, CD, DE) grouped into two chains: (AB) and (CD, DE).\n\/\/ Similarly, an Shape representing 5 points would have 5 chains consisting\n\/\/ of one edge each.\n\/\/\n\/\/ Shape has methods that allow edges to be accessed either using the global\n\/\/ numbering (edge ID) or within a particular chain. The global numbering is\n\/\/ sufficient for most purposes, but the chain representation is useful for\n\/\/ certain algorithms such as intersection (see BooleanOperation).\ntype Shape interface {\n\t\/\/ NumEdges returns the number of edges in this shape.\n\tNumEdges() int\n\n\t\/\/ Edge returns the edge for the given edge index.\n\tEdge(i int) Edge\n\n\t\/\/ HasInterior reports whether this shape has an interior.\n\tHasInterior() bool\n\n\t\/\/ ReferencePoint returns an arbitrary reference point for the shape. (The\n\t\/\/ containment boolean value must be false for shapes that do not have an interior.)\n\t\/\/\n\t\/\/ This reference point may then be used to compute the containment of other\n\t\/\/ points by counting edge crossings.\n\tReferencePoint() ReferencePoint\n\n\t\/\/ NumChains reports the number of contiguous edge chains in the shape.\n\t\/\/ For example, a shape whose edges are [AB, BC, CD, AE, EF] would consist\n\t\/\/ of two chains (AB,BC,CD and AE,EF). Every chain is assigned a chain Id\n\t\/\/ numbered sequentially starting from zero.\n\t\/\/\n\t\/\/ Note that it is always acceptable to implement this method by returning\n\t\/\/ NumEdges, i.e. every chain consists of a single edge, but this may\n\t\/\/ reduce the efficiency of some algorithms.\n\tNumChains() int\n\n\t\/\/ Chain returns the range of edge IDs corresponding to the given edge chain.\n\t\/\/ Edge chains must form contiguous, non-overlapping ranges that cover\n\t\/\/ the entire range of edge IDs. This is spelled out more formally below:\n\t\/\/\n\t\/\/  0 <= i < NumChains()\n\t\/\/  Chain(i).length > 0, for all i\n\t\/\/  Chain(0).start == 0\n\t\/\/  Chain(i).start + Chain(i).length == Chain(i+1).start, for i < NumChains()-1\n\t\/\/  Chain(i).start + Chain(i).length == NumEdges(), for i == NumChains()-1\n\tChain(chainID int) Chain\n\n\t\/\/ ChainEdgeReturns the edge at offset \"offset\" within edge chain \"chainID\".\n\t\/\/ Equivalent to \"shape.Edge(shape.Chain(chainID).start + offset)\"\n\t\/\/ but more efficient.\n\tChainEdge(chainID, offset int) Edge\n\n\t\/\/ ChainPosition finds the chain containing the given edge, and returns the\n\t\/\/ position of that edge as a ChainPosition(chainID, offset) pair.\n\t\/\/\n\t\/\/  shape.Chain(pos.chainID).start + pos.offset == edgeID\n\t\/\/  shape.Chain(pos.chainID+1).start > edgeID\n\t\/\/\n\t\/\/ where pos == shape.ChainPosition(edgeID).\n\tChainPosition(edgeID int) ChainPosition\n\n\t\/\/ dimension returns the dimension of the geometry represented by this shape.\n\t\/\/\n\t\/\/  pointGeometry: Each point is represented as a degenerate edge.\n\t\/\/\n\t\/\/  polylineGeometry:  Polyline edges may be degenerate. A shape may\n\t\/\/      represent any number of polylines. Polylines edges may intersect.\n\t\/\/\n\t\/\/  polygonGeometry:  Edges should be oriented such that the polygon\n\t\/\/      interior is always on the left.

has a file position calculated as described below.\n\/\/   interface{} : will be passed any value\n\/\/\n\/\/ Position calculation\n\/\/\n\/\/ There is some extra handling when a parameter is being coerced into a\n\/\/ token.Pos, token.Position or Range type argument.\n\/\/\n\/\/ If the parameter is an identifier, it will be treated as the name of an\n\/\/ marker to look up (as if markers were global variables).\n\/\/\n\/\/ If it is a string or regular expression, then it will be passed to\n\/\/ expect.MatchBefore to look up a match in the line at which it was declared.\n\/\/\n\/\/ It is

The wrappedError details are not exported. If an error is\n\/\/ the kind of error a caller should need to investigate, an IsXError()\n\/\/ function is provided that tells the caller if the error is of that type.\n\/\/ There should only be a handfull of cases where a simple `error` is\n\/\/ insufficient.\n\/\/\n\/\/ The error behaviors can be nested when created.

avoid recomputing it every\n\t\/\/ time. Adding a new label to the object that the federation is\n\t\/\/ unaware of causes problems because federated controllers compare\n\t\/\/ the objects in federation and their equivalents in clusters and\n\t\/\/ try to reconcile them. This leads to a constant fight between the\n\t\/\/ federated daemonset controller and the cluster controllers, and\n\t\/\/ they never reach a stable state.\n\t\/\/\n\t\/\/ Ideally, cluster components should not update an object's spec or\n\t\/\/ metadata in a way federation cannot replicate. They can update an\n\t\/\/ object's status though. Therefore, this daemonset hash should\n\t\/\/ be a field in daemonset's status, not a label in object meta.\n\t\/\/ @janetkuo says that this label is only a short term solution. In\n\t\/\/ the near future, they are going to replace it with revision numbers\n\t\/\/ in daemonset status. We can then rip this bandaid out.\n\t\/\/\n\t\/\/ We are deleting the keys here and that should be fine since we are\n\t\/\/ working on object copies. Also, propagating the deleted labels\n\t\/\/ should also be fine because we don't support daemonset rolling\n\t\/\/ update in federation yet.\n\tdelete(daemonset1.ObjectMeta.Labels, extensionsv1.DefaultDaemonSetUniqueLabelKey)\n\tdelete(daemonset2.ObjectMeta.Labels, extensionsv1.DefaultDaemonSetUniqueLabelKey)\n\n\treturn util.ObjectMetaEquivalent(daemonset1.ObjectMeta, daemonset2.ObjectMeta) && reflect.DeepEqual(daemonset1.Spec, daemonset2.Spec)\n}\n\nfunc (a *DaemonSetAdapter) NamespacedName(obj pkgruntime.Object) types.NamespacedName {\n\tdaemonset := obj.(*extensionsv1.DaemonSet)\n\treturn types.NamespacedName{Namespace: daemonset.Namespace, Name: daemonset.Name}\n}\n\nfunc (a *DaemonSetAdapter) ObjectMeta(obj pkgruntime.Object) *metav1.ObjectMeta {\n\treturn &obj.(*extensionsv1.DaemonSet).ObjectMeta\n}\n\nfunc (a *DaemonSetAdapter) FedCreate(obj pkgruntime.Object) (pkgruntime.Object, error) {\n\tdaemonset := obj.(*extensionsv1.DaemonSet)\n\treturn a.client.Extensions().DaemonSets(daemonset.Namespace).Create(daemonset)\n}\n\nfunc (a *DaemonSetAdapter) FedDelete(namespacedName types.NamespacedName, options *metav1.DeleteOptions) error {\n\treturn a.client.Extensions().DaemonSets(namespacedName.Namespace).Delete(namespacedName.Name, options)\n}\n\nfunc (a *DaemonSetAdapter) FedGet(namespacedName types.NamespacedName) (pkgruntime.Object, error) {\n\treturn a.client.Extensions().DaemonSets(namespacedName.Namespace).Get(namespacedName.Name, metav1.GetOptions{})\n}\n\nfunc (a *DaemonSetAdapter) FedList(namespace string, options metav1.ListOptions) (pkgruntime.Object, error) {\n\treturn a.client.Extensions().DaemonSets(namespace).List(options)\n}\n\nfunc (a *DaemonSetAdapter) FedUpdate(obj pkgruntime.Object) (pkgruntime.Object, error) {\n\tdaemonset := obj.(*extensionsv1.DaemonSet)\n\treturn a.client.Extensions().DaemonSets(daemonset.Namespace).Update(daemonset)\n}\n\nfunc (a *DaemonSetAdapter) FedWatch(namespace string, options metav1.ListOptions) (watch.Interface, error) {\n\treturn a.client.Extensions().DaemonSets(namespace).Watch(options)\n}\n\nfunc (a *DaemonSetAdapter) ClusterCreate(client kubeclientset.Interface, obj pkgruntime.Object) (pkgruntime.Object, error) {\n\tdaemonset := obj.(*extensionsv1.DaemonSet)\n\treturn client.Extensions().DaemonSets(daemonset.Namespace).Create(daemonset)\n}\n\nfunc (a *DaemonSetAdapter) ClusterDelete(client kubeclientset.Interface, nsName types.NamespacedName, options *metav1.DeleteOptions) error {\n\treturn client.Extensions().DaemonSets(nsName.Namespace).Delete(nsName.Name, options)\n}\n\nfunc (a *DaemonSetAdapter) ClusterGet(client kubeclientset.Interface, namespacedName types.NamespacedName) (pkgruntime.Object, error) {\n\treturn client.Extensions().DaemonSets(namespacedName.Namespace).Get(namespacedName.Name, metav1.GetOptions{})\n}\n\nfunc (a *DaemonSetAdapter) ClusterList(client kubeclientset.Interface, namespace string, options metav1.ListOptions) (pkgruntime.Object, error) {\n\treturn client.Extensions().DaemonSets(namespace).List(options)\n}\n\nfunc (a *DaemonSetAdapter) ClusterUpdate(client kubeclientset.Interface, obj pkgruntime.Object) (pkgruntime.Object, error) {\n\tdaemonset := obj.(*extensionsv1.DaemonSet)\n\treturn client.Extensions().DaemonSets(daemonset.Namespace).Update(daemonset)\n}\n\nfunc (a *DaemonSetAdapter) ClusterWatch(client kubeclientset.Interface, namespace string, options metav1.ListOptions) (watch.Interface, error) {\n\treturn client.Extensions().DaemonSets(namespace).Watch(options)\n}\n\nfunc (a *DaemonSetAdapter) IsSchedulingAdapter() bool {\n\treturn false\n}\n\nfunc (a *DaemonSetAdapter) NewTestObject(namespace string) pkgruntime.Object {\n\treturn &extensionsv1.DaemonSet{\n\t\tObjectMeta: metav1.ObjectMeta{\n\t\t\tGenerateName: \"test-daemonset-\",\n\t\t\tNamespace:    namespace,\n\t\t\tLabels:       map[string]string{\"app\": \"test-daemonset\"},\n\t\t},\n\t\tSpec: extensionsv1.DaemonSetSpec{\n\t\t\tTemplate: v1.PodTemplateSpec{\n\t\t\t\tObjectMeta: metav1.ObjectMeta{\n\t\t\t\t\tLabels: map[string]string{\"name\": \"test-pod\"},\n\t\t\t\t},\n\t\t\t\tSpec: v1.PodSpec{\n\t\t\t\t\tContainers: []v1.Container{\n\t\t\t\t\t\t{\n\t\t\t\t\t\t\tName:  \"test-daemonset\",\n\t\t\t\t\t\t\tImage: \"images\/test-daemonset\",\n\t\t\t\t\t\t\tPorts: []v1.ContainerPort{{ContainerPort: 9376}},\n\t\t\t\t\t\t},\n\t\t\t\t\t},\n\t\t\t\t},\n\t\t\t},\n\t\t},\n\t}\n}\n<|endoftext|>"}

{"text":"<commit_before>\/\/ Package lumberjack provides a rolling logger.\n\/\/\n\/\/ Lumberjack is intended to be one part of a logging infrastructure.\n\/\/ It is not an all-in-one solution, but instead is a pluggable\n\/\/ component at the bottom of the logging stack that simply controls the files\n\/\/ to which logs are written.\n\/\/\n\/\/ Lumberjack plays well with any logger that can write to an io.Writer,\n\/\/ including the standard library's log package.\n\/\/\n\/\/ Lumberjack assumes that only one process is writing to the output files.\n\/\/ Using the same lumberjack configuration from multiple processes on the same\n\/\/ machine will result in improper behavior.\npackage lumberjack\n\nimport (\n\t\"fmt\"\n\t\"io\"\n\t\"io\/ioutil\"\n\t\"os\"\n\t\"path\/filepath\"\n\t\"sort\"\n\t\"sync\"\n\t\"time\"\n)\n\nconst (\n\t\/\/ Some helper constants to make your declarations easier to read.\n\n\tMegabyte = 1024 * 1024\n\tGigabyte = 1024 * Megabyte\n\n\t\/\/ Note that lumberjack days and weeks may not exactly conform to calendar\n\t\/\/ days and weeks due to daylight savings, leap seconds, etc.\n\n\tDay  = 24 * time.Hour\n\tWeek = 7 * Day\n\n\tdefaultNameFormat = \"2006-01-02T15-04-05.000.log\"\n\tdefaultMaxSize    = 100 * Megabyte\n)\n\n\/\/ ensure we always implement io.WriteCloser\nvar _ io.WriteCloser = (*Logger)(nil)\n\n\/\/ Logger is an io.WriteCloser that writes to a log file in the given directory\n\/\/ with the given NameFormat.  NameFormat should include a time formatting\n\/\/ layout in it that produces a valid unique filename for the OS.  For more\n\/\/ about time formatting layouts, read http:\/\/golang.org\/pkg\/time\/#pkg-constants.\n\/\/\n\/\/ The date encoded in the filename by NameFormat is used to determine which log\n\/\/ files are most recent in several situations.\n\/\/\n\/\/ Logger opens or creates a logfile on first Write.  It looks for files in the\n\/\/ directory that match its name format, and if the one with the most recent\n\/\/ NameFormat date is less than MaxSize, it will open and append to that file.\n\/\/ If no such file exists, or the file is >= MaxSize, a new file is created\n\/\/ using the current time with NameFormat to generate the filename.\n\/\/\n\/\/ Whenever a write would cause the current log file exceed MaxSize, a new file\n\/\/ is created using the current time.\n\/\/\n\/\/ Cleaning Up Old Log Files\n\/\/\n\/\/ Whenever a new file gets created, old log files may be deleted.  The log file\n\/\/ directory is scanned for files that match NameFormat.  The most recent files\n\/\/ according to their NameFormat date will be retained, up to a number equal to\n\/\/ MaxBackups (or all of them if MaxBackups is 0).  Any files with a last\n\/\/ modified time (based on FileInfo.ModTime) older than MaxAge are deleted,\n\/\/ regardless of MaxBackups.\n\/\/\n\/\/ If MaxBackups and MaxAge are both 0, no old log files will be deleted.\ntype Logger struct {\n\t\/\/ Dir determines the directory in which to store log files.\n\t\/\/ It defaults to os.TempDir() if empty.\n\tDir string `json:\"dir\" yaml:\"dir\"`\n\n\t\/\/ NameFormat is the time formatting layout used to generate filenames.\n\t\/\/ It defaults to \"2006-01-02T15-04-05.000.log\".\n\tNameFormat string `json:\"nameformat\" yaml:\"nameformat\"`\n\n\t\/\/ MaxSize is the maximum size in bytes of the log file before it gets\n\t\/\/ rolled. It defaults to 100 megabytes.\n\tMaxSize int64 `json:\"maxsize\" yaml:\"maxsize\"`\n\n\t\/\/ MaxAge is the maximum time to retain old log files based on\n\t\/\/ FileInfo.ModTime.  The default is not to remove old log files based on\n\t\/\/ age.\n\tMaxAge time.Duration `json:\"maxage\" yaml:\"maxage\"`\n\n\t\/\/ MaxBackups is the maximum number of old log files to retain.  The default\n\t\/\/ is to retain all old log files (though MaxAge may still cause them to get\n\t\/\/ deleted.)\n\tMaxBackups int `json:\"maxbackups\" yaml:\"maxbackups\"`\n\n\t\/\/ LocalTime determines if the time used for formatting the filename is the\n\t\/\/ computer's local time.  The default is to use UTC time.\n\tLocalTime bool `json:\"localtime\" yaml:\"localtime\"`\n\n\tsize int64\n\tfile *os.File\n\tmu   sync.Mutex\n}\n\n\/\/ currentTime is only used for testing. Normally it's the time.Now() function.\nvar currentTime = time.Now\n\n\/\/ Write implements io.Writer.  If a write would cause the log file to be larger\n\/\/ than MaxSize, a new log file is created using the current time formatted with\n\/\/ PathFormat.

be one part of a logging infrastructure.\n\/\/ It is not an all-in-one solution, but instead is a pluggable\n\/\/ component at the bottom of the logging stack that simply controls the files\n\/\/ to which logs are written.\n\/\/\n\/\/ Lumberjack plays well with any logger that can write to an io.Writer,\n\/\/ including the standard library's log package.\n\/\/\n\/\/ Lumberjack assumes that only one process is writing to the output files.\n\/\/ Using the same lumberjack configuration from multiple processes on the same\n\/\/ machine will result in improper behavior.\npackage lumberjack\n\nimport (\n\t\"fmt\"\n\t\"io\"\n\t\"io\/ioutil\"\n\t\"os\"\n\t\"path\/filepath\"\n\t\"sort\"\n\t\"sync\"\n\t\"time\"\n)\n\nconst (\n\t\/\/ Some helper constants to make your declarations easier to read.\n\n\tMegabyte = 1024 * 1024\n\tGigabyte = 1024 * Megabyte\n\n\t\/\/ Note that lumberjack days and weeks may not exactly conform to calendar\n\t\/\/ days and weeks due to daylight

implement io.WriteCloser\nvar _ io.WriteCloser = (*Logger)(nil)\n\n\/\/ Logger is an io.WriteCloser that writes to a log file in the given directory\n\/\/ with the given NameFormat.  NameFormat should include a time formatting\n\/\/ layout in it that produces a valid unique filename for the OS.  For more\n\/\/ about time formatting layouts, read http:\/\/golang.org\/pkg\/time\/#pkg-constants.\n\/\/\n\/\/ The date encoded in the filename by NameFormat is used to determine which log\n\/\/ files are most recent in several situations.\n\/\/\n\/\/ Logger opens or creates a logfile on first Write.  It looks for files in the\n\/\/ directory that match its name format, and if the one with the most recent\n\/\/ NameFormat date is less than MaxSize, it will open and append to that file.\n\/\/ If no such file exists, or the file is >= MaxSize, a new file is created\n\/\/ using the current time with NameFormat to generate the filename.\n\/\/\n\/\/ Whenever a write would cause the current log file exceed MaxSize, a new file\n\/\/ is created using the current time.\n\/\/\n\/\/ Cleaning Up Old Log Files\n\/\/\n\/\/ Whenever a new file gets created, old log files may be deleted.  The log file\n\/\/ directory is scanned for files that match NameFormat.  The most recent files\n\/\/ according to their NameFormat date will be retained, up to a number equal to\n\/\/ MaxBackups (or all of them if MaxBackups is 0).  Any files with a last\n\/\/ modified time (based on FileInfo.ModTime) older than MaxAge are deleted,\n\/\/ regardless of MaxBackups.\n\/\/\n\/\/ If MaxBackups and MaxAge are both 0, no old log files will be deleted.\ntype Logger struct {\n\t\/\/ Dir determines the directory in which to store log files.\n\t\/\/ It defaults to os.TempDir() if empty.\n\tDir string `json:\"dir\" yaml:\"dir\"`\n\n\t\/\/ NameFormat is the time formatting layout used to generate filenames.\n\t\/\/ It defaults to \"2006-01-02T15-04-05.000.log\".\n\tNameFormat string `json:\"nameformat\" yaml:\"nameformat\"`\n\n\t\/\/ MaxSize is the maximum size in bytes of the log file before it gets\n\t\/\/ rolled. It defaults to 100 megabytes.\n\tMaxSize int64 `json:\"maxsize\" yaml:\"maxsize\"`\n\n\t\/\/ MaxAge is the maximum time to retain old log files based on\n\t\/\/ FileInfo.ModTime.  The default is not to remove old log files based on\n\t\/\/ age.\n\tMaxAge time.Duration `json:\"maxage\" yaml:\"maxage\"`\n\n\t\/\/ MaxBackups is the maximum number of old log files to retain.  The default\n\t\/\/ is to retain all old log files (though MaxAge may still cause them to get\n\t\/\/ deleted.)\n\tMaxBackups int `json:\"maxbackups\" yaml:\"maxbackups\"`\n\n\t\/\/ LocalTime determines if the time used for formatting the filename is the\n\t\/\/ computer's local time.
