This puts backups in an odd position,\nparticularly with regard to the storage of backup metadata and\narchives.  As a result, here are a couple concerns worth mentioning.\n\nFirst, as noted above backup is about state but not a part of state.\nSo exposing backup-related methods on State would imply the wrong\nthing.  Thus the backup functionality here in the state package (not\nstate\/backups) is exposed as functions to which you pass a state\nobject.\n\nSecond, backup creates an archive file containing a dump of state's\nmongo DB.  Storing backup metadata\/archives in mongo is thus a\nsomewhat circular proposition that has the potential to cause\nproblems.  That may need further attention.\n\nNote that state (and juju as a whole) currently does not have a\npersistence layer abstraction to facilitate separating different\npersistence needs and implementations.  As a consequence, state's\ndata, whether about how an environment should look or about existing\nresources within an environment, is dumped essentially straight into\nState's mongo connection.  The code in the state package does not\nmake any distinction between the two (nor does the package clearly\ndistinguish between state-related abstractions and state-related\ndata).\n\nBackup adds yet another category, merely taking advantage of\nState's DB.  In the interest of making the distinction clear, the\ncode that directly interacts with State (and its DB) lives in this\nfile.  As mentioned previously, the functionality here is exposed\nthrough functions that take State, rather than as methods on State.\nFurthermore, the bulk of the backup-related code, which does not need\ndirect interaction with State, lives in the state\/backups package.\n*\/\n\n\/\/ NewBackupsOrigin returns a snapshot of where backup was run.\nfunc NewBackupsOrigin(st *State, machine string)

This puts backups in an odd position,\nparticularly with regard to the storage of backup metadata and\narchives.  As a result, here are a couple concerns worth mentioning.\n\nFirst, as noted above backup is about state but not a part of state.\nSo exposing backup-related methods on State would imply the wrong\nthing.  Thus the backup functionality here in the state package (not\nstate\/backups) is exposed as functions to which you pass a state\nobject.\n\nSecond, backup creates an archive file containing a dump of state's\nmongo DB.  Storing backup metadata\/archives in mongo is thus a\nsomewhat circular proposition that has the potential to cause\nproblems.  That may need further attention.\n\nNote that state (and juju as a whole) currently does not have a\npersistence layer abstraction to facilitate separating different\npersistence needs and implementations.  As a consequence, state's\ndata, whether about how an environment should look or about existing\nresources within an environment, is dumped essentially straight into\nState's mongo connection.  The code in the state package does not\nmake any distinction between the two (nor does the package clearly\ndistinguish between state-related abstractions and state-related\ndata).\n\nBackup adds yet another category, merely taking advantage of\nState's DB.  In the interest of making the distinction clear, the\ncode that directly interacts with State (and its DB) lives in this\nfile.  As mentioned previously, the functionality here is exposed\nthrough functions that take State, rather than as methods on State.\nFurthermore, the bulk of the backup-related code, which does not need\ndirect interaction with State, lives in the state\/backups package.\n*\/\n\n\/\/ backupMetadataDoc is a mirror of metadata.Metadata, used just for DB storage.\ntype backupMetadataDoc struct {\n\tID             string `bson:\"_id\"`\n\tStarted        int64  `bson:\"started,minsize\"`\n\tFinished       int64  `bson:\"finished,minsize\"`\n\tChecksum       string `bson:\"checksum\"`\n\tChecksumFormat string `bson:\"checksumformat\"`\n\tSize           int64  `bson:\"size,minsize\"`\n\tStored         bool   `bson:\"stored\"`\n\tNotes          string `bson:\"notes,omitempty\"`\n\n\t\/\/ origin\n\tEnvironment string         `bson:\"environment\"`\n\tMachine     string         `bson:\"machine\"`\n\tHostname    string         `bson:\"hostname\"`\n\tVersion     version.Number `bson:\"version\"`\n}\n\nfunc (doc *backupMetadataDoc) validate() error {\n\tif doc.ID == \"\" {\n\t\treturn errors.New(\"missing ID\")\n\t}\n\tif doc.Started == 0 {\n\t\treturn errors.New(\"missing Started\")\n\t}\n\tif doc.Environment == \"\" {\n\t\treturn errors.New(\"missing Environment\")\n\t}\n\tif doc.Machine == \"\" {\n\t\treturn errors.New(\"missing Machine\")\n\t}\n\tif doc.Hostname == \"\" {\n\t\treturn errors.New(\"missing Hostname\")\n\t}\n\tif doc.Version.Major == 0 {\n\t\treturn errors.New(\"missing Version\")\n\t}\n\n\t\/\/ Check the \"finished\" fields.\n\tif doc.Finished == 0 {\n\t\tif doc.Checksum == \"\" {\n\t\t\tif doc.ChecksumFormat == \"\" {\n\t\t\t\tif doc.Size == 0 {\n\t\t\t\t\tif doc.Stored {\n\t\t\t\t\t\treturn errors.New(\"Stored unexpected set\")\n\t\t\t\t\t}\n\t\t\t\t\treturn nil\n\t\t\t\t}\n\t\t\t}\n\t\t}\n\t\treturn errors.New(\"missing finished\")\n\t}\n\tif doc.Checksum == \"\" {\n\t\treturn errors.New(\"missing finished\")\n\t}\n\tif doc.ChecksumFormat == \"\" {\n\t\treturn errors.New(\"missing finished\")\n\t}\n\tif doc.Size == 0 {\n\t\treturn errors.New(\"missing finished\")\n\t}\n\n\treturn nil\n}\n\n\/\/ asMetadata returns a new backups.Metadata based on the backupMetadataDoc.\nfunc (doc *backupMetadataDoc) asMetadata() *metadata.Metadata {\n\t\/\/ Create a new Metadata.\n\torigin := metadata.NewOrigin(\n\t\tdoc.Environment,\n\t\tdoc.Machine,\n\t\tdoc.Hostname,\n\t\tdoc.Version,\n\t)\n\n\tstarted := time.Unix(doc.Started, 0).UTC()\n\tmeta := metadata.NewMetadata(\n\t\t*origin,\n\t\tdoc.Notes,\n\t\t&started,\n\t)\n\n\t\/\/ The ID is already set.\n\tmeta.SetID(doc.ID)\n\n\t\/\/ Set the \"finished\" fields.\n\tif doc.Finished == 0 {\n\t\tif doc.Checksum == \"\" {\n\t\t\tif doc.ChecksumFormat == \"\" {\n\t\t\t\tif doc.Size == 0 {\n\t\t\t\t\t\/\/ Not finished so exit early.\n\t\t\t\t\treturn meta\n\t\t\t\t}\n\t\t\t}\n\t\t}\n\t}\n\tvar finished *time.Time\n\tif doc.Finished != 0 {\n\t\tval := time.Unix(doc.Finished, 0).UTC()\n\t\tfinished = &val\n\t}\n\terr := meta.Finish(doc.Size, doc.Checksum, doc.ChecksumFormat, finished)\n\tif err != nil {\n\t\tpanic(\"invalid metadata doc\")\n\t}\n\tif doc.Stored {\n\t\tmeta.SetStored()\n\t}\n\treturn meta\n}\n\n\/\/ updateFromMetadata copies the corresponding data from the metadata.Metadata\n\/\/ into the backupMetadataDoc.\nfunc (doc *backupMetadataDoc) updateFromMetadata(metadata *metadata.Metadata) {\n\tfinished := metadata.Finished()\n\t\/\/ Ignore metadata.ID.\n\tdoc.Started = metadata.Started().Unix()\n\tif finished != nil {\n\t\tdoc.Finished = finished.Unix()\n\t}\n\tdoc.Checksum = metadata.Checksum()\n\tdoc.ChecksumFormat = metadata.ChecksumFormat()\n\tdoc.Size = metadata.Size()\n\tdoc.Stored = metadata.Stored()\n\tdoc.Notes = metadata.Notes()\n\n\torigin := metadata.Origin()\n\tdoc.Environment = origin.Environment()\n\tdoc.Machine = origin.Machine()\n\tdoc.Hostname = origin.Hostname()\n\tdoc.Version = origin.Version()\n}\n\n\/\/---------------------------\n\/\/ DB operations\n\n\/\/ getBackupMetadata returns the backup metadata associated with \"id\".\n\/\/ If \"id\" does not match any stored records, an error satisfying\n\/\/ juju\/errors.IsNotFound() is returned.\nfunc getBackupMetadata(st *State, id string) (*metadata.Metadata, error) {\n\tcollection, closer := st.getCollection(backupsMetaC)\n\tdefer closer()\n\n\tvar doc backupMetadataDoc\n\t\/\/ There can only be one!\n\terr := collection.FindId(id).One(&doc)\n\tif err == mgo.ErrNotFound {\n\t\treturn nil, errors.NotFoundf(\"backup metadata %q\", id)\n\t} else if err != nil {\n\t\treturn nil, errors.Annotate(err, \"error getting backup metadata\")\n\t}\n\n\tif err := doc.validate(); err != nil {\n\t\treturn nil, errors.Trace(err)\n\t}\n\treturn doc.asMetadata(), nil\n}\n\n\/\/ addBackupMetadata stores metadata for a backup where it can be\n\/\/ accessed later.

This is the time to install moves onto the manager by\n\t\/\/returning a list of moves to install. Typically you use moves.Combine\n\t\/\/and friends to organize your list of moves to install. If the moves you\n\t\/\/add are illegal for any reason, NewGameManager will fail with an error.\n\t\/\/By the time this is called. delegate.SetManager will already have been\n\t\/\/called, so you'll have access to the manager via Manager().\n\tConfigureMoves() []MoveConfig\n\n\t\/\/ConfigureAgents will be called when creating a new GameManager. Emit the\n\t\/\/agents you want to install.\n\tConfigureAgents() []Agent\n\n\t\/\/ConfigureDecks will be called when the GameManager is being booted up.\n\t\/\/Each entry in the return value will be configured on the ComponentChest\n\t\/\/that is being created.\n\tConfigureDecks() map[string]*Deck\n\n\t\/\/ConfigureEnums is called during set up of a new GameManager. Return the\n\t\/\/set of enums you want to be associated with this GameManagaer's Chest.\n\tConfigureEnums() *enum.Set\n\n\t\/\/ConfigureConstants is called during set-up of a new GameManager. Return\n\t\/\/the map of constants you want to create, which will be configured onto\n\t\/\/the newly created chest via AddConstant. If any of the AddConstant calls\n\t\/\/errors, the GameManager will fail to be set up. Constants are primarily\n\t\/\/useful in two cases: first, when you want to have access to a constant\n\t\/\/value client-side, and second, when you want to be able to use a\n\t\/\/constant value in a tag-based struct inflater.\n\tConfigureConstants() PropertyCollection\n\n\t\/\/GameStateConstructor and PlayerStateConstructor are called to get an\n\t\/\/instantiation of the concrete game\/player structs that your package\n\t\/\/defines. This is used both to create the initial state, but also to\n\t\/\/inflate states from the database. These methods should always return the\n\t\/\/underlying same type of struct when called. This means that if different\n\t\/\/players have very different roles in a game, there might be many\n\t\/\/properties that are not in use for any given player. The simple\n\t\/\/properties (ints, bools, strings) should all be their zero-value.\n\t\/\/Importantly, all Stacks, Timers, and Enums should be non- nil, because\n\t\/\/an initialized struct contains information about things like MaxSize,\n\t\/\/Size, and a reference to the deck they are affiliated with. GameManger\n\t\/\/will automatically create and use StructInflaters for these types of\n\t\/\/objects, allowing you to use tag-based configuration to automatically\n\t\/\/inflate these properties. See the documentation for StructInflater for\n\t\/\/more. Since these two methods are always required and always specific to\n\t\/\/each game type, defaultGameDelegate does not implement them, as an extra\n\t\/\/reminder that you must implement them yourself.\n\tGameStateConstructor() ConfigurableSubState\n\t\/\/PlayerStateConstructor is similar to GameStateConstructor, but\n\t\/\/playerIndex is the value that this PlayerState must return when its\n\t\/\/PlayerIndex() is called.\n\tPlayerStateConstructor(player PlayerIndex) ConfigurablePlayerState\n\n\t\/\/DynamicComponentValuesConstructor returns an empty\n\t\/\/DynamicComponentValues for the given deck. If nil is returned, then the\n\t\/\/components in that deck don't have any dynamic component state. This\n\t\/\/method must always return the same underlying type of struct for the\n\t\/\/same deck. Like GameStateConstructor and PlayerStateConstructor, the\n\t\/\/engine will automatically create StructInflaters for these objects,\n\t\/\/allowing you to use tag-based inflation of properties. See StructInflate\n\t\/\/for more. If the returned object also implements the ComponentValues\n\t\/\/interface, then SetContainingComponent will be called on the\n\t\/\/DynamicComponent whenever one is created, with a reference back to the\n\t\/\/component it's associated with.\n\tDynamicComponentValuesConstructor(deck *Deck) ConfigurableSubState\n\n\t\/\/DistributeComponentToStarterStack is called during set up to establish\n\t\/\/the Deck\/Stack invariant that every component in the chest is placed in\n\t\/\/precisely one Stack. Game will call this on each component in the Chest\n\t\/\/in order. This is where the logic goes to make sure each Component goes\n\t\/\/into its correct starter stack. You must return a non-nil Stack for each\n\t\/\/call, after which the given Component will be inserted into\n\t\/\/NextSlotIndex of that stack. If that is not the ordering you desire, you\n\t\/\/can fix it up in FinishSetUp by using SwapComponents. If any errors are\n\t\/\/returned, any nil Stacks are returned, or any returned stacks don't have\n\t\/\/space for another component, NewGame will fail and return an error.\n\t\/\/State and Component are only provided for reference; do not modify them.\n\tDistributeComponentToStarterStack(state ImmutableState, c Component) (ImmutableStack, error)\n\n\t\/\/BeginSetup is a chance to modify the initial state object *before* the\n\t\/\/components are distributed to it. It is also where the variant\n\t\/\/configuration for your gametype will be passed (it will already have\n\t\/\/been checked for legality and had all configure defaults set), although\n\t\/\/you can also retrieve that at any time via game.Variant(). This is a\n\t\/\/good place to configure state that will be necessary for you to make the\n\t\/\/right decisions in DistributeComponentToStarterStack, or to transcribe\n\t\/\/config information you were passed into properties on your gameState as\n\t\/\/appropriate. If error is non-nil, Game setup will be aborted, with the\n\t\/\/reasoning including the error message provided.\n\tBeginSetUp(state State, variant Variant) error\n\n\t\/\/FinishSetUp is called during NewGame, *after* components have been\n\t\/\/distributed to their StarterStack. This is the last chance to modify the\n\t\/\/state before the game's initial state is considered final. For example,\n\t\/\/if you have a card game this is where you'd make sure the starter draw\n\t\/\/stacks are shuffled. If your game has multiple rounds, or if you don't\n\t\/\/want the game to start with it already set-up (e.g. you want to show\n\t\/\/animations of starter cards being dealt) then it's probably best to do\n\t\/\/most of the logic in a SetUp phase. See the README for more. If error is\n\t\/\/non-nil, Game setup will be aborted, with the reasoning including the\n\t\/\/error message provided.\n\tFinishSetUp(state State) error\n\n\t\/\/CheckGameFinished should return true if the game is finished, and who\n\t\/\/the winners are. Called after every move is applied.\n\tCheckGameFinished(state ImmutableState) (finished bool, winners []PlayerIndex)\n\n\t\/\/ProposeFixUpMove is called after a move has been applied. It may return\n\t\/\/a FixUp move, which will be applied before any other moves are applied.\n\t\/\/If it returns nil, we may take the next move off of the queue. FixUp\n\t\/\/moves are useful for things like shuffling a discard deck back into a\n\t\/\/draw deck, or other moves that are necessary to get the GameState back\n\t\/\/into reasonable shape.\n\tProposeFixUpMove(state ImmutableState) 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\/\/manager.NewGame(), we wil use this value instead.\n\tDefaultNumPlayers() int\n\n\t\/\/Min\/MaxNumPlayers should return the min and max number of players,\n\t\/\/respectively. The engine doesn't use this directly, instead looking at\n\t\/\/LegalNumPlayers. Typically your LegalNumPlayers will check the given\n\t\/\/number of players is between these two extremes.\n\tMinNumPlayers() int\n\tMaxNumPlayers() int\n\n\t\/\/LegalNumPlayers will be consulted when a new game is created. It should\n\t\/\/return true if the given number of players is legal, and false\n\t\/\/otherwise. If this returns false, the NewGame will fail with an error.\n\t\/\/Game creation will automatically reject a numPlayers that does not\n\t\/\/result in at least one player existing. Generally this is simply\n\t\/\/checking to make sure the number of players is between Min and Max\n\t\/\/(inclusive), although some games could only allow, for example, even\n\t\/\/numbers of players.\n\tLegalNumPlayers(numPlayers int) bool\n\n\t\/\/Variants returns a VariantConfig, which describes the different\n\t\/\/categories of configuration values and the legal values they may take\n\t\/\/on. Ultimately your LegalVariant is the final arbiter of which variants\n\t\/\/are legal; this method is mainly used so that user interfaces know which\n\t\/\/variants to show to the user. In general you shouldn't call this, but\n\t\/\/instead call gameManager.Variants() which will ensure your VariantConfig\n\t\/\/is initalized and memoize the return result.\n\tVariants() VariantConfig\n\n\t\/\/CurrentPlayerIndex returns the index of the \"current\" player--a notion\n\t\/\/that is game specific (and sometimes inapplicable). If CurrentPlayer\n\t\/\/doesn't make sense (perhaps the game never has a notion of current\n\t\/\/player, or the type of round that we're in has no current player), this\n\t\/\/should return ObserverPlayerIndex. The result of this method is used to\n\t\/\/power state.CurrentPlayer.\n\tCurrentPlayerIndex(state ImmutableState) PlayerIndex\n\n\t\/\/CurrentPhase returns the phase that the game state is currently in.\n\t\/\/Phase is a formalized convention used in moves.Base to make it easier to\n\t\/\/write fix-up moves that only apply in certain phases, like SetUp. The\n\t\/\/return result is primarily used in moves.Base to check whether it is one\n\t\/\/of the phases in a give Move's LegalPhases. See moves.Base for more\n\t\/\/information.\n\tCurrentPhase(state ImmutableState) int\n\n\t\/\/PhaseEnum returns the enum for game phases (the return values of\n\t\/\/CurrentPhase are expected to be valid enums within that enum). If this\n\t\/\/returns a non-nil enums.TreeEnum, then the state will not be able to be\n\t\/\/saved if CurrentPhase() returns a value that is not a leaf-node.\n\tPhaseEnum() enum.Enum\n\n\t\/\/SanitizationPolicy is consulted when sanitizing states. It is called for\n\t\/\/each prop in the state, including the set of groups that this player is\n\t\/\/a mamber of. In practice the default behavior of defaultGameDelegate,\n\t\/\/which uses struct tags to figure out the policy, is sufficient and you\n\t\/\/do not need to override this. For more on how sanitization works, see\n\t\/\/the package doc. The statePropetyRef passed will always have the Index\n\t\/\/properties set to -1, signifying that the returned policy applies to all\n\t\/\/items in the Stack\/Board.\n\tSanitizationPolicy(prop StatePropertyRef, groupMembership map[int]bool) Policy\n\n\t\/\/If you have computed properties that you want to be included in your\n\t\/\/JSON (for example, for use clientside), export them here by creating a\n\t\/\/dictionary with their values.\n\tComputedGlobalProperties(state ImmutableState) PropertyCollection\n\tComputedPlayerProperties(player ImmutablePlayerState) PropertyCollection\n\n\t\/\/Diagram should return a basic debug rendering of state in multi-line\n\t\/\/ascii art.

This means that if different\n\t\/\/players have very different roles in a game, there might be many\n\t\/\/properties that are not in use for any given player. The simple\n\t\/\/properties (ints, bools, strings) should all be their zero-value.\n\t\/\/Importantly, all Stacks, Timers, and Enums should be non- nil, because\n\t\/\/an initialized struct contains information about things like MaxSize,\n\t\/\/Size, and a reference to the deck they are affiliated with. GameManger\n\t\/\/will automatically create and use StructInflaters for these types of\n\t\/\/objects, allowing you to use tag-based configuration to automatically\n\t\/\/inflate these properties. See the documentation for StructInflater for\n\t\/\/more. Since these two methods are always required and always specific to\n\t\/\/each game type, defaultGameDelegate does not implement them, as an extra\n\t\/\/reminder that you must implement them yourself.\n\tGameStateConstructor() ConfigurableSubState\n\t\/\/PlayerStateConstructor is similar to GameStateConstructor, but\n\t\/\/playerIndex is the value that this PlayerState must return when its\n\t\/\/PlayerIndex() is called.\n\tPlayerStateConstructor(player PlayerIndex) ConfigurablePlayerState\n\n\t\/\/DynamicComponentValuesConstructor returns an empty\n\t\/\/DynamicComponentValues for the given deck. If nil is returned, then the\n\t\/\/components in that deck don't have any dynamic component state. This\n\t\/\/method must always return the same underlying type of struct for the\n\t\/\/same deck. Like GameStateConstructor and PlayerStateConstructor, the\n\t\/\/engine will automatically create StructInflaters for these objects,\n\t\/\/allowing you to use tag-based inflation of properties. See StructInflate\n\t\/\/for more. If the returned object also implements the ComponentValues\n\t\/\/interface, then SetContainingComponent will be called on the\n\t\/\/DynamicComponent whenever one is created, with a reference back to the\n\t\/\/component it's associated with.\n\tDynamicComponentValuesConstructor(deck *Deck) ConfigurableSubState\n\n\t\/\/DistributeComponentToStarterStack is called during set up to establish\n\t\/\/the Deck\/Stack invariant that every component in the chest is placed in\n\t\/\/precisely one Stack. Game will call this on each component in the Chest\n\t\/\/in order. This is where the logic goes to make sure each Component goes\n\t\/\/into its correct starter stack. You must return a non-nil Stack for each\n\t\/\/call, after which the given Component will be inserted into\n\t\/\/NextSlotIndex of that stack. If that is not the ordering you desire, you\n\t\/\/can fix it up in FinishSetUp by using SwapComponents. If any errors are\n\t\/\/returned, any nil Stacks are returned, or any returned stacks don't have\n\t\/\/space for another component, NewGame will fail and return an error.\n\t\/\/State and Component are only provided for reference; do not modify them.\n\tDistributeComponentToStarterStack(state ImmutableState, c Component) (ImmutableStack, error)\n\n\t\/\/BeginSetup is a chance to modify the initial state object *before* the\n\t\/\/components are distributed to it. It is also where the variant\n\t\/\/configuration for your gametype will be passed (it will already have\n\t\/\/been checked for legality and had all configure defaults set), although\n\t\/\/you can also retrieve that at any time via game.Variant(). This is a\n\t\/\/good place to configure state that will be necessary for you to make the\n\t\/\/right decisions in DistributeComponentToStarterStack, or to transcribe\n\t\/\/config information you were passed into properties on your gameState as\n\t\/\/appropriate. If error is non-nil, Game setup will be aborted, with the\n\t\/\/reasoning including the error message provided.\n\tBeginSetUp(state State, variant Variant) error\n\n\t\/\/FinishSetUp is called during NewGame, *after* components have been\n\t\/\/distributed to their StarterStack. This is the last chance to modify the\n\t\/\/state before the game's initial state is considered final. For example,\n\t\/\/if you have a card game this is where you'd make sure the starter draw\n\t\/\/stacks are shuffled. If your game has multiple rounds, or if you don't\n\t\/\/want the game to start with it already set-up (e.g. you want to show\n\t\/\/animations of starter cards being dealt) then it's probably best to do\n\t\/\/most of the logic in a SetUp phase. See the README for more. If error is\n\t\/\/non-nil, Game setup will be aborted, with the reasoning including the\n\t\/\/error message provided.\n\tFinishSetUp(state State) error\n\n\t\/\/CheckGameFinished should return true if the game is finished, and who\n\t\/\/the winners are. Called after every move is applied.\n\tCheckGameFinished(state ImmutableState) (finished bool, winners []PlayerIndex)\n\n\t\/\/ProposeFixUpMove is called after a move has been applied. It may return\n\t\/\/a FixUp move, which will be applied before any other moves are applied.\n\t\/\/If it returns nil, we may take the next move off of the queue. FixUp\n\t\/\/moves are useful for things like shuffling a discard deck back into a\n\t\/\/draw deck, or other moves that are necessary to get the GameState back\n\t\/\/into reasonable shape.\n\tProposeFixUpMove(state ImmutableState) 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\/\/manager.NewGame(), we wil use this value instead.\n\tDefaultNumPlayers() int\n\n\t\/\/Min\/MaxNumPlayers should return the min and max number of players,\n\t\/\/respectively. The engine doesn't use this directly, instead looking at\n\t\/\/LegalNumPlayers. Typically your LegalNumPlayers will check the given\n\t\/\/number of players is between these two extremes.\n\tMinNumPlayers() int\n\tMaxNumPlayers() int\n\n\t\/\/LegalNumPlayers will be consulted when a new game is created. It should\n\t\/\/return true if the given number of players is legal, and false\n\t\/\/otherwise. If this returns false, the NewGame will fail with an error.\n\t\/\/Game creation will automatically reject a numPlayers that does not\n\t\/\/result in at least one player existing. Generally this is simply\n\t\/\/checking to make sure the number of players is between Min and Max\n\t\/\/(inclusive), although some games could only allow, for example, even\n\t\/\/numbers of players.\n\tLegalNumPlayers(numPlayers int) bool\n\n\t\/\/Variants returns a VariantConfig, which describes the different\n\t\/\/categories of configuration values and the legal values they may take\n\t\/\/on. Ultimately your LegalVariant is the final arbiter of which variants\n\t\/\/are legal; this method is mainly used so that user interfaces know which\n\t\/\/variants to show to the user. In general you shouldn't call this, but\n\t\/\/instead call gameManager.Variants() which will ensure your VariantConfig\n\t\/\/is initalized and memoize the return result.\n\tVariants() VariantConfig\n\n\t\/\/CurrentPlayerIndex returns the index of the \"current\" player--a notion\n\t\/\/that is game specific (and sometimes inapplicable). If CurrentPlayer\n\t\/\/doesn't make sense (perhaps the game never has a notion of current\n\t\/\/player, or the type of round that we're in has no current player), this\n\t\/\/should return ObserverPlayerIndex. The result of this method is used to\n\t\/\/power state.CurrentPlayer.\n\tCurrentPlayerIndex(state ImmutableState) PlayerIndex\n\n\t\/\/CurrentPhase returns the phase that the game state is currently in.\n\t\/\/Phase is a formalized convention used in moves.Base to make it easier to\n\t\/\/write fix-up moves that only apply in certain phases, like SetUp. The\n\t\/\/return result is primarily used in moves.Base to check whether it is one\n\t\/\/of the phases in a give Move's LegalPhases. See moves.Base for more\n\t\/\/information.\n\tCurrentPhase(state ImmutableState) int\n\n\t\/\/PhaseEnum returns the enum for game phases (the return values of\n\t\/\/CurrentPhase are expected to be valid enums within that enum). If this\n\t\/\/returns a non-nil enums.TreeEnum, then the state will not be able to be\n\t\/\/saved if CurrentPhase() returns a value that is not a leaf-node.\n\tPhaseEnum() enum.Enum\n\n\t\/\/SanitizationPolicy is consulted when sanitizing states. It is called for\n\t\/\/each prop in the state, including the set of groups that this player is\n\t\/\/a mamber of. In practice the default behavior of defaultGameDelegate,\n\t\/\/which uses struct tags to figure out the policy, is sufficient and you\n\t\/\/do not need to override this. For more on how sanitization works, see\n\t\/\/the package doc. The statePropetyRef passed will always have the Index\n\t\/\/properties set to -1, signifying that the returned policy applies to all\n\t\/\/items in the Stack\/Board.\n\tSanitizationPolicy(prop StatePropertyRef, groupMembership map[int]bool) Policy\n\n\t\/\/If you have computed properties that you want to be included in your\n\t\/\/JSON (for example, for use clientside), export them here by creating a\n\t\/\/dictionary with their values.\n\tComputedGlobalProperties(state ImmutableState) PropertyCollection\n\tComputedPlayerProperties(player ImmutablePlayerState) PropertyCollection\n\n\t\/\/Diagram should return a basic debug rendering of state in multi-line\n\t\/\/ascii art. Useful for debugging. State.Diagram() will reach out to this\n\t\/\/method.\n\tDiagram(s ImmutableState) string\n\n\t\/\/SetManager configures which manager this delegate is in use with. A\n\t\/\/given delegate can only be used by a single manager at a time.\n\tSetManager(manager *GameManager)\n\n\t\/\/Manager returns the Manager that was set on this delegate.\n\tManager() *GameManager\n}\n\n\/\/PropertyCollection is just an alias for map[string]interface{}\ntype PropertyCollection map[string]interface{}\n\n\/\/Copy returns a shallow copy of PropertyCollection\nfunc (p PropertyCollection) Copy() PropertyCollection {\n\tresult := make(PropertyCollection, len(p))\n\tfor key, val := range result {\n\t\tresult[key] = val\n\t}\n\treturn result\n}\n<|endoftext|>"}

{"text":"<commit_before>\/*\nPackage mangle is a sanitization \/ data masking library for Go (golang).\n\n\nPurpose\n\nThis library provides functionality to sanitize text and HTML data. This can be integrated into tools that export or manipulate databases\/files so that confidential data is not exposed to staging, development or testing systems.\n\nGetting Started\n\nInstall mangle:\n\n\t\tgo get github.com\/grugnog\/mangle\n\nTry the command line tool:\n\n\t\tgo get github.com\/grugnog\/mangle\/manglefile\n\n\t\t# Generate a list of words using your system dictionary and download \"War and Peace\" for testing.\n\t\taspell -d en dump master | aspell -l en expand > corpus.txt\n\t\twget http:\/\/www.gutenberg.org\/cache\/epub\/2600\/pg2600.txt\n\n\t\t# Run the sample text through manglefile via stdin and stdout.\n\t\tcat pg2600.txt | manglefile -corpus=corpus.txt -secret=replace-with-a-secure-passphrase | less\n\nFor basic usage of mangle as a Go library for strings, see the Example below.  For usage using io.Reader\/io.Writer for text and html, see the manglefile source code.\n\nDescription\n\nSecure - every non-punctuation, non-tag word is replaced, with no reuse of source words.\n\nFast - around 350,000 words\/sec (\"War and Peace\" mangled in < 2s).\n\nDeterministic - words are selected from a corpus deterministically - subsequent runs will result in the same word replacements as long as the user secret is not changed.

This can be integrated into tools that export or manipulate databases\/files so that confidential data is not exposed to staging, development or testing systems.\n\nGetting Started\n\nInstall mangle:\n\n\t\tgo get github.com\/grugnog\/mangle\n\nTry the command line tool:\n\n\t\tgo get github.com\/grugnog\/mangle\/manglefile\n\n\t\t# Generate a list of words using your system dictionary and download \"War and Peace\" for testing.\n\t\taspell -d en dump master | aspell -l en expand > corpus.txt\n\t\twget http:\/\/www.gutenberg.org\/cache\/epub\/2600\/pg2600.txt\n\n\t\t# Run the sample text through manglefile via stdin and stdout.\n\t\tcat pg2600.txt | manglefile -corpus=corpus.txt -secret=replace-with-a-secure-passphrase | less\n\nFor basic usage of mangle as a Go library for strings, see the Example below.  For usage using io.Reader\/io.Writer for text and html, see the manglefile source code.\n\nDescription\n\nSecure - every non-punctuation, non-tag word is replaced, with no reuse of source words.\n\nFast - around 350,000 words\/sec (\"War and Peace\" mangled in < 2s).\n\nDeterministic - words are selected from a corpus deterministically - subsequent runs will result in the same word replacements as long as the user secret is not changed. This allows automated tests to run against the sanitized data, as well as for efficient rsync's of mangled versions of large slowly changing data sets.\n\nAccurate - maintains a high level of resemblance to the source text, to allow for realistic testing of search indexes, page layout etc. Replacement words are all natural words from a user defined corpus.

Please use \"extraArgs\" in \"apiServer\" to configure this feature instead.\n\/\/ - \"unifiedControlPlaneImage\" in ClusterConfiguration was changed to a boolean field called \"useHyperKubeImage\".\n\/\/ - ClusterConfiguration now has a \"dns\" field which can be used to select and configure the cluster DNS addon.\n\/\/ - Both \"localEtcd\" and \"dns\" configurations now support custom image repositories.\n\/\/ - the \"controlPlane*\" related fields in JoinConfiguration were refactored into a sub structure.\n\/\/ - \"clusterName\" was removed from JoinConfiguration and the name is now fetched from the existing cluster.\n\/\/\n\/\/ Migration from old kubeadm config versions\n\/\/\n\/\/ Please convert your v1alpha3 configuration files to v1beta1 using the \"kubeadm config migrate\" command of kubeadm v1.13.x\n\/\/ (conversion from older releases of kubeadm config files requires older release of kubeadm as well e.g.\n\/\/\tkubeadm v1.11 should be used to migrate v1alpha1 to v1alpha2; kubeadm v1.12 should be used to translate v1alpha2 to v1alpha3)\n\/\/\n\/\/ Nevertheless, kubeadm v1.13.x will support reading from v1alpha3 version of the kubeadm config file format, but this support\n\/\/ will be dropped in the v1.14 release.\n\/\/\n\/\/ Basics\n\/\/\n\/\/ The preferred way to configure kubeadm is to pass an YAML configuration file with the --config option.

Please use \"extraArgs\" in \"apiServer\" to configure this feature instead.\n\/\/\t- \"unifiedControlPlaneImage\" in ClusterConfiguration was changed to a boolean field called \"useHyperKubeImage\".\n\/\/\t- ClusterConfiguration now has a \"dns\" field which can be used to select and configure the cluster DNS addon.\n\/\/\t- \"featureGates\" still exists under ClusterConfiguration, but there are no supported feature gates in 1.13.\n\/\/\tSee the Kubernetes 1.13 changelog for further details.\n\/\/\t- Both \"localEtcd\" and \"dns\" configurations now support custom image repositories.\n\/\/\t- the \"controlPlane*\" related fields in JoinConfiguration were refactored into a sub structure.\n\/\/\t- \"clusterName\" was removed from JoinConfiguration and the name is now fetched from the existing cluster.\n\/\/\n\/\/ Migration from old kubeadm config versions\n\/\/\n\/\/ Please convert your v1alpha3 configuration files to v1beta1 using the \"kubeadm config migrate\" command of kubeadm v1.13.x\n\/\/ (conversion from older releases of kubeadm config files requires older release of kubeadm as well e.g.\n\/\/\tkubeadm v1.11 should be used to migrate v1alpha1 to v1alpha2; kubeadm v1.12 should be used to translate v1alpha2 to v1alpha3)\n\/\/\n\/\/ Nevertheless, kubeadm v1.13.x will support reading from v1alpha3 version of the kubeadm config file format, but this support\n\/\/ will be dropped in the v1.14 release.\n\/\/\n\/\/ Basics\n\/\/\n\/\/ The preferred way to configure kubeadm is to pass an YAML configuration file with the --config option.

Some of the\n\/\/ configuration options defined in the kubeadm config file are also available as command line flags, but only\n\/\/ the most common\/simple use case are supported with this approach.\n\/\/\n\/\/ A kubeadm config file could contain multiple configuration types separated using three dashes (“---”).\n\/\/\n\/\/ kubeadm supports the following configuration types:\n\/\/\n\/\/     apiVersion: kubeadm.k8s.io\/v1beta3\n\/\/     kind: InitConfiguration\n\/\/\n\/\/     apiVersion: kubeadm.k8s.io\/v1beta3\n\/\/     kind: ClusterConfiguration\n\/\/\n\/\/     apiVersion: kubelet.config.k8s.io\/v1beta1\n\/\/     kind: KubeletConfiguration\n\/\/\n\/\/     apiVersion: kubeproxy.config.k8s.io\/v1alpha1\n\/\/     kind: KubeProxyConfiguration\n\/\/\n\/\/     apiVersion: kubeadm.k8s.io\/v1beta3\n\/\/     kind: JoinConfiguration\n\/\/\n\/\/ To print the defaults for \"init\" and \"join\" actions use the following commands:\n\/\/  kubeadm config print init-defaults\n\/\/  kubeadm config print join-defaults\n\/\/\n\/\/ The list of configuration types that must be included in a configuration file depends by the action you are\n\/\/ performing (init or join) and by the configuration options you are going to use (defaults or advanced customization).\n\/\/\n\/\/ If some configuration types are not provided, or provided only partially, kubeadm will use default values; defaults\n\/\/ provided by kubeadm includes also enforcing consistency of values across components when required (e.g.\n\/\/ cluster-cidr flag on controller manager and clusterCIDR on kube-proxy).\n\/\/\n\/\/ Users are always allowed to override default values, with the only exception of a small subset of setting with\n\/\/ relevance for security (e.g. enforce authorization-mode Node and RBAC on api server)\n\/\/\n\/\/ If the user provides a configuration types that is not expected for the action you are performing, kubeadm will\n\/\/ ignore those types and print a warning.\n\/\/\n\/\/ Kubeadm init configuration types\n\/\/\n\/\/ When executing kubeadm init with the --config option, the following configuration types could be used:\n\/\/ InitConfiguration, ClusterConfiguration, KubeProxyConfiguration, KubeletConfiguration, but only one\n\/\/ between InitConfiguration and ClusterConfiguration is mandatory.\n\/\/\n\/\/     apiVersion: kubeadm.k8s.io\/v1beta3\n\/\/     kind: InitConfiguration\n\/\/     bootstrapTokens:\n\/\/         ...\n\/\/     nodeRegistration:\n\/\/         ...\n\/\/\n\/\/ The InitConfiguration type should be used to configure runtime settings, that in case of kubeadm init\n\/\/ are the configuration of the bootstrap token and all the setting which are specific to the node where kubeadm\n\/\/ is executed, including:\n\/\/\n\/\/ - NodeRegistration, that holds fields that relate to registering the new node to the cluster;\n\/\/ use it to customize the node name, the CRI socket to use or any other settings that should apply to this\n\/\/ node only (e.g. the node ip).\n\/\/\n\/\/ - LocalAPIEndpoint, that represents the endpoint of the instance of the API server to be deployed on this node;\n\/\/ use it e.g. to customize the API server advertise address.\n\/\/\n\/\/     apiVersion: kubeadm.k8s.io\/v1beta3\n\/\/     kind: ClusterConfiguration\n\/\/     networking:\n\/\/         ...\n\/\/     etcd:\n\/\/         ...\n\/\/     apiServer:\n\/\/       extraArgs:\n\/\/         ...\n\/\/       extraVolumes:\n\/\/         ...\n\/\/     ...\n\/\/\n\/\/ The ClusterConfiguration type should be used to configure cluster-wide settings,\n\/\/ including settings for:\n\/\/\n\/\/ - Networking, that holds configuration for the networking topology of the cluster; use it e.g. to customize\n\/\/ pod subnet or services subnet.\n\/\/\n\/\/ - Etcd configurations; use it e.g. to customize the local etcd or to configure the API server\n\/\/ for using an external etcd cluster.\n\/\/\n\/\/ - kube-apiserver, kube-scheduler, kube-controller-manager configurations; use it to customize control-plane\n\/\/ components by adding customized setting or overriding kubeadm default settings.\n\/\/\n\/\/    apiVersion: kubeproxy.config.k8s.io\/v1alpha1\n\/\/    kind: KubeProxyConfiguration\n\/\/       ...\n\/\/\n\/\/ The KubeProxyConfiguration type should be used to change the configuration passed to kube-proxy instances deployed\n\/\/ in the cluster.

The package\n\/\/ API follows the less-is-more principle, by presenting a small, clean interface.\n\/\/\n\/\/ The package dns supports (asynchronous) querying\/replying, incoming\/outgoing AXFR\/IXFR,\n\/\/ TSIG, EDNS0, dynamic updates, notifies and DNSSEC validation\/signing.\n\/\/ Note that domain names MUST be fully qualified, before sending them, unqualified\n\/\/ names in a message will result in a packing failure.\n\/\/\n\/\/ Resource records are native types. They are not stored in wire format.\n\/\/ Basic usage pattern for creating a new resource record:\n\/\/\n\/\/      r := new(dns.MX)\n\/\/      r.Hdr = dns.RR_Header{Name: \"miek.nl.\", Rrtype: dns.TypeMX, Class: dns.ClassINET, Ttl: 3600}\n\/\/      r.Pref = 10\n\/\/      r.Mx = \"mx.miek.nl.\"\n\/\/\n\/\/ Or directly from a string:\n\/\/\n\/\/      mx, err := dns.NewRR(\"miek.nl. 3600 IN MX 10 mx.miek.nl.\")\n\/\/\n\/\/ Or when the default TTL (3600) and class (IN) suit you:\n\/\/\n\/\/      mx, err := dns.NewRR(\"miek.nl. MX 10 mx.miek.nl.\")\n\/\/\n\/\/ Or even:\n\/\/\n\/\/      mx, err := dns.NewRR(\"$ORIGIN nl.\\nmiek 1H IN MX 10 mx.miek\")\n\/\/\n\/\/ In the DNS messages are exchanged, these messages contain resource\n\/\/ records (sets).

Either or both of the flags may be replaced with the\n\tcharacter '*', causing their values to be obtained from the next\n\toperand, which must be of type int.\n\n\tFor numeric values, width sets the minimum width of the field and\n\tprecision sets the number of places after the decimal, if appropriate,\n\texcept that for %g\/%G it sets the total number of digits. For example,\n\tgiven 123.45 the format %6.2f prints 123.45 while %.4g prints 123.5.\n\tThe default precision for %e and %f is 6; for %g it is the smallest\n\tnumber of digits necessary to identify the value uniquely.\n\n\tFor most values, width is the minimum number of characters to output,\n\tpadding the formatted form with spaces if necessary.\n\tFor strings, precision is the maximum number of characters to output,\n\ttruncating if necessary.\n\n\tOther flags:\n\t\t+\talways print a sign for numeric values;\n\t\t\tguarantee ASCII-only output for %q (%+q)\n\t\t-\tpad with spaces on the right rather than the left (left-justify the field)\n\t\t#\talternate format: add leading 0 for octal (%#o), 0x for hex (%#x);\n\t\t\t0X for hex (%#X); suppress 0x for %p (%#p);\n\t\t\tfor %q, print a raw (backquoted) string if strconv.CanBackquote\n\t\t\treturns true;\n\t\t\twrite e.g. U+0078 'x' if the character is printable for %U (%#U).\n\t\t' '\t(space) leave a space for elided sign in numbers (% d);\n\t\t\tput spaces between bytes printing strings or slices in hex (% x, % X)\n\t\t0\tpad with leading zeros rather than spaces;\n\t\t\tfor numbers, this moves the padding after the sign\n\n\tFlags are ignored by verbs that do not expect them.\n\tFor example there is no alternate decimal format, so %#d and %d\n\tbehave identically.\n\n\tFor each Printf-like function, there is also a Print function\n\tthat takes no format and is equivalent to saying %v for every\n\toperand.  Another variant Println inserts blanks between\n\toperands and appends a newline.\n\n\tRegardless of the verb, if an operand is an interface value,\n\tthe internal concrete value is used, not the interface itself.\n\tThus:\n\t\tvar i interface{} = 23\n\t\tfmt.Printf(\"%v\\n\", i)\n\twill print 23.\n\n\tIf an operand implements interface Formatter, that interface\n\tcan be used for fine control of formatting.\n\n\tIf the format (which is implicitly %v for Println etc.) is valid\n\tfor a string (%s %q %v %x %X), the following two rules also apply:\n\n\t1. If an operand implements the error interface, the Error method\n\twill be used to convert the object to a string, which will then\n\tbe formatted as required by the verb (if any).\n\n\t2. If an operand implements method String() string, that method\n\twill be used to convert the object to a string, which will then\n\tbe formatted as required by the verb (if any).\n\n\tTo avoid recursion in cases such as\n\t\ttype X string\n\t\tfunc (x X) String() string { return Sprintf(\"<%s>\", x) }\n\tconvert the value before recurring:\n\t\tfunc (x X) String() string { return Sprintf(\"<%s>\", string(x)) }\n\n\tExplicit argument indexes:\n\n\tIn Printf, Sprintf, and Fprintf, the default behavior is for each\n\tformatting verb to format successive arguments passed in the call.\n\tHowever, the notation [n] immediately before the verb indicates that the\n\tnth one-indexed argument is to be formatted instead. The same notation\n\tbefore a '*' for a width or precision selects the argument index holding\n\tthe value. After processing a bracketed expression [n], arguments n+1,\n\tn+2, etc. will be processed unless otherwise directed.\n\n\tFor example,\n\t\tfmt.Sprintf(\"%[2]d %[1]d\\n\", 11, 22)\n\twill yield \"22, 11\", while\n\t\tfmt.Sprintf(\"%[3]*.[2]*[1]f\", 12.0, 2, 6),\n\tequivalent to\n\t\tfmt.Sprintf(\"%6.2f\", 12.0),\n\twill yield \" 12.00\". Because an explicit index affects subsequent verbs,\n\tthis notation can be used to print the same values multiple times\n\tby resetting the index for the first argument to be repeated:\n\t\tfmt.Sprintf(\"%d %d %#[1]x %#x\", 16, 17)\n\twill yield \"16 17 0x10 0x11\".\n\n\tFormat errors:\n\n\tIf an invalid argument is given for a verb, such as providing\n\ta string to %d, the generated string will contain a\n\tdescription of the problem, as in these examples:\n\n\t\tWrong type or unknown verb: %!verb(type=value)\n\t\t\tPrintf(\"%d\", hi):          %!d(string=hi)\n\t\tToo many arguments: %!(EXTRA type=value)\n\t\t\tPrintf(\"hi\", \"guys\"):      hi%!(EXTRA string=guys)\n\t\tToo few arguments: %!verb(MISSING)\n\t\t\tPrintf(\"hi%d\"):            hi %!d(MISSING)\n\t\tNon-int for width or precision: %!(BADWIDTH) or %!(BADPREC)\n\t\t\tPrintf(\"%*s\", 4.5, \"hi\"):  %!(BADWIDTH)hi\n\t\t\tPrintf(\"%.*s\", 4.5, \"hi\"): %!(BADPREC)hi\n\t\tInvalid or invalid use of argument index: %!(BADINDEX)\n\t\t\tPrintf(\"%*[2]d\", 7):       %!d(BADINDEX)\n\t\t\tPrintf(\"%.[2]d\", 7):       %!d(BADINDEX)\n\n\tAll errors begin with the string \"%!\" followed sometimes\n\tby a single character (the verb) and end with a parenthesized\n\tdescription.\n\n\tIf an Error or String method triggers a panic when called by a\n\tprint routine, the fmt package reformats the error message\n\tfrom the panic, decorating it with an indication that it came\n\tthrough the fmt package.  For example, if a String method\n\tcalls panic(\"bad\"), the resulting formatted message will look\n\tlike\n\t\t%!s(PANIC=bad)\n\n\tThe %!s just shows the print verb in use when the failure\n\toccurred.\n\n\tScanning\n\n\tAn analogous set of functions scans formatted text to yield\n\tvalues.  Scan, Scanf and Scanln read from os.Stdin; Fscan,\n\tFscanf and Fscanln read from a specified io.Reader; Sscan,\n\tSscanf and Sscanln read from an argument string.  Scanln,\n\tFscanln and Sscanln stop scanning at a newline and require that\n\tthe items be followed by one; Scanf, Fscanf and Sscanf require\n\tnewlines in the input to match newlines in the format; the other\n\troutines treat newlines as spaces.\n\n\tScanf, Fscanf, and Sscanf parse the arguments according to a\n\tformat string, analogous to that of Printf.  For example, %x\n\twill scan an integer as a hexadecimal number, and %v will scan\n\tthe default representation format for the value.\n\n\tThe formats behave analogously to those of Printf with the\n\tfollowing exceptions:\n\n\t\t%p is not implemented\n\t\t%T is not implemented\n\t\t%e %E %f %F %g %G are all equivalent and scan any floating point or complex value\n\t\t%s and %v on strings scan a space-delimited token\n\t\tFlags # and + are not implemented.\n\n\tThe familiar base-setting prefixes 0 (octal) and 0x\n\t(hexadecimal) are accepted when scanning integers without a\n\tformat or with the %v verb.\n\n\tWidth is interpreted in the input text (%5s means at most\n\tfive runes of input will be read to scan a string) but there\n\tis no syntax for scanning with a precision (no %5.2f, just\n\t%5f).\n\n\tWhen scanning with a format, all non-empty runs of space\n\tcharacters (except newline) are equivalent to a single\n\tspace in both the format and the input.  With that proviso,\n\ttext in the format string must match the input text; scanning\n\tstops if it does not, with the return value of the function\n\tindicating the number of arguments scanned.\n\n\tIn all the scanning functions, a carriage return followed\n\timmediately by a newline is treated as a plain newline\n\t(\\r\\n means the same as \\n).\n\n\tIn all the scanning functions, if an operand implements method\n\tScan (that is, it implements the Scanner interface) that\n\tmethod will be used to scan the text for that operand.  Also,\n\tif the number of arguments scanned is less than the number of\n\targuments provided, an error is returned.\n\n\tAll arguments to be scanned must be either pointers to basic\n\ttypes or implementations of the Scanner interface.\n\n\tNote: Fscan etc. can read one character (rune) past the input\n\tthey return, which means that a loop calling a scan routine\n\tmay skip some of the input.  This is usually a problem only\n\twhen there is no space between input values.  If the reader\n\tprovided to Fscan implements ReadRune, that method will be used\n\tto read characters.  If the reader also implements UnreadRune,\n\tthat method will be used to save the character and successive\n\tcalls will not lose data.  To attach ReadRune and UnreadRune\n\tmethods to a reader without that capability, use\n\tbufio.NewReader.\n*\/\npackage fmt\n<commit_msg>fmt: improve documentation for width and precision Fixes issue 7048.<commit_after>\/\/ Copyright 2009 The Go Authors.

For example, if a String method\n\tcalls panic(\"bad\"), the resulting formatted message will look\n\tlike\n\t\t%!s(PANIC=bad)\n\n\tThe %!s just shows the print verb in use when the failure\n\toccurred.\n\n\tScanning\n\n\tAn analogous set of functions scans formatted text to yield\n\tvalues.  Scan, Scanf and Scanln read from os.Stdin; Fscan,\n\tFscanf and Fscanln read from a specified io.Reader; Sscan,\n\tSscanf and Sscanln read from an argument string.  Scanln,\n\tFscanln and Sscanln stop scanning at a newline and require that\n\tthe items be followed by one; Scanf, Fscanf and Sscanf require\n\tnewlines in the input to match newlines in the format; the other\n\troutines treat newlines as spaces.\n\n\tScanf, Fscanf, and Sscanf parse the arguments according to a\n\tformat string, analogous to that of Printf.  For example, %x\n\twill scan an integer as a hexadecimal number, and %v will scan\n\tthe default representation format for the value.\n\n\tThe formats behave analogously to those of Printf with the\n\tfollowing exceptions:\n\n\t\t%p is not implemented\n\t\t%T is not implemented\n\t\t%e %E %f %F %g %G are all equivalent and scan any floating point or complex value\n\t\t%s and %v on strings scan a space-delimited token\n\t\tFlags # and + are not implemented.\n\n\tThe familiar base-setting prefixes 0 (octal) and 0x\n\t(hexadecimal) are accepted when scanning integers without a\n\tformat or with the %v verb.\n\n\tWidth is interpreted in the input text (%5s means at most\n\tfive runes of input will be read to scan a string) but there\n\tis no syntax for scanning with a precision (no %5.2f, just\n\t%5f).\n\n\tWhen scanning with a format, all non-empty runs of space\n\tcharacters (except newline) are equivalent to a single\n\tspace in both the format and the input.  With that proviso,\n\ttext in the format string must match the input text; scanning\n\tstops if it does not, with the return value of the function\n\tindicating the number of arguments scanned.\n\n\tIn all the scanning functions, a carriage return followed\n\timmediately by a newline is treated as a plain newline\n\t(\\r\\n means the same as \\n).\n\n\tIn all the scanning functions, if an operand implements method\n\tScan (that is, it implements the Scanner interface) that\n\tmethod will be used to scan the text for that operand.  Also,\n\tif the number of arguments scanned is less than the number of\n\targuments provided, an error is returned.\n\n\tAll arguments to be scanned must be either pointers to basic\n\ttypes or implementations of the Scanner interface.\n\n\tNote: Fscan etc. can read one character (rune) past the input\n\tthey return, which means that a loop calling a scan routine\n\tmay skip some of the input.  This is usually a problem only\n\twhen there is no space between input values.  If the reader\n\tprovided to Fscan implements ReadRune, that method will be used\n\tto read characters.  If the reader also implements UnreadRune,\n\tthat method will be used to save the character and successive\n\tcalls will not lose data.  To attach ReadRune and UnreadRune\n\tmethods to a reader without that capability, use\n\tbufio.NewReader.\n*\/\npackage fmt\n<|endoftext|>"}

There is no int8, int16 etc.\ndiscrimination in the gob format; there are only signed and unsigned integers.  As\ndescribed below, the transmitter sends the value in a variable-length encoding;\nthe receiver accepts the value and stores it in the destination variable.\nFloating-point numbers are always sent using IEEE-754 64-bit precision (see\nbelow).\n\nSigned integers may be received into any signed integer variable: int, int16, etc.;\nunsigned integers may be received into any unsigned integer variable; and floating\npoint values may be received into any floating point variable.

Attempting\nto encode a value that contains one will fail.\n\nThe rest of this comment documents the encoding, details that are not important\nfor most users.  Details are presented bottom-up.\n\nAn unsigned integer is sent one of two ways.  If it is less than 128, it is sent\nas a byte with that value.  Otherwise it is sent as a minimal-length big-endian\n(high byte first) byte stream holding the value, preceded by one byte holding the\nbyte count, negated.  Thus 0 is transmitted as (00), 7 is transmitted as (07) and\n256 is transmitted as (FE 01 00).\n\nA boolean is encoded within an unsigned integer: 0 for false, 1 for true.\n\nA signed integer, i, is encoded within an unsigned integer, u.  Within u, bits 1\nupward contain the value; bit 0 says whether they should be complemented upon\nreceipt.  The encode algorithm looks like this:\n\n\tuint u;\n\tif i < 0 {\n\t\tu = (^i << 1) | 1\t\/\/ complement i, bit 0 is 1\n\t} else {\n\t\tu = (i << 1)\t\/\/ do not complement i, bit 0 is 0\n\t}\n\tencodeUnsigned(u)\n\nThe low bit is therefore analogous to a sign bit, but making it the complement bit\ninstead guarantees that the largest negative integer is not a special case.  For\nexample, -129=^128=(^256>>1) encodes as (FE 01 01).\n\nFloating-point numbers are always sent as a representation of a float64 value.\nThat value is converted to a uint64 using math.Float64bits.  The uint64 is then\nbyte-reversed and sent as a regular unsigned integer.  The byte-reversal means the\nexponent and high-precision part of the mantissa go first.  Since the low bits are\noften zero, this can save encoding bytes.  For instance, 17.0 is encoded in only\nthree bytes (FE 31 40).\n\nStrings and slices of bytes are sent as an unsigned count followed by that many\nuninterpreted bytes of the value.\n\nAll other slices and arrays are sent as an unsigned count followed by that many\nelements using the standard gob encoding for their type, recursively.\n\nStructs are sent as a sequence of (field number, field value) pairs.  The field\nvalue is sent using the standard gob encoding for its type, recursively.  If a\nfield has the zero value for its type, it is omitted from the transmission.  The\nfield number is defined by the type of the encoded struct: the first field of the\nencoded type is field 0, the second is field 1, etc.  When encoding a value, the\nfield numbers are delta encoded for efficiency and the fields are always sent in\norder of increasing field number; the deltas are therefore unsigned.  The\ninitialization for the delta encoding sets the field number to -1, so an unsigned\ninteger field 0 with value 7 is transmitted as unsigned delta = 1, unsigned value\n= 7 or (01 0E).  Finally, after all the fields have been sent a terminating mark\ndenotes the end of the struct.  That mark is a delta=0 value, which has\nrepresentation (00).\n\nInterface types are not checked for compatibility; all interface types are\ntreated, for transmission, as members of a single \"interface\" type, analogous to\nint or []byte - in effect they're all treated as interface{}.  Interface values\nare transmitted as a string identifying the concrete type being sent (a name\nthat must be pre-defined by calling Register()), followed by the usual encoding\nof concrete (dynamic) value stored in the interface value.  (A nil interface\nvalue is identified by the empty string and transmits no value.) Upon receipt,\nthe decoder verifies that the unpacked concrete item satisfies the interface of\nthe receiving variable.\n\nThe representation of types is described below.  When a type is defined on a given\nconnection between an Encoder and Decoder, it is assigned a signed integer type\nid.  When Encoder.Encode(v) is called, it makes sure there is an id assigned for\nthe type of v and all its elements and then it sends the pair (typeid, encoded-v)\nwhere typeid is the type id of the encoded type of v and encoded-v is the gob\nencoding of the value v.\n\nTo define a type, the encoder chooses an unused, positive type id and sends the\npair (-type id, encoded-type) where encoded-type is the gob encoding of a wireType\ndescription, constructed from these types:\n\n\ttype wireType struct {\n\t\ts\tstructType;\n\t}\n\ttype arrayType struct {\n\t\tcommonType\n\t\tElem typeId\n\t\tLen  int\n\t}\n\ttype commonType {\n\t\tname\tstring;\t\/\/ the name of the struct type\n\t\tid\tint;\t\/\/ the id of the type, repeated for so it's inside the type\n\t}\n\ttype sliceType struct {\n\t\tcommonType\n\t\tElem typeId\n\t}\n\ttype structType struct {\n\t\tcommonType;\n\t\tfield\t[]fieldType;\t\/\/ the fields of the struct.\n\t}\n\ttype fieldType struct {\n\t\tname\tstring;\t\/\/ the name of the field.\n\t\tid\tint;\t\/\/ the type id of the field, which must be already defined\n\t}\n\ttype mapType struct {\n\t\tcommonType\n\t\tKey  typeId\n\t\tElem typeId\n\t}\n\nIf there are nested type ids, the types for all inner type ids must be defined\nbefore the top-level type id is used to describe an encoded-v.\n\nFor simplicity in setup, the connection is defined to understand these types a\npriori, as well as the basic gob types int, uint, etc.  Their ids are:\n\n\tbool        1\n\tint         2\n\tuint        3\n\tfloat       4\n\t[]byte      5\n\tstring      6\n\tcomplex     7\n\tinterface   8\n\t\/\/ gap for reserved ids.\n\twireType    16\n\tarrayType  17\n\tcommonType 18\n\tsliceType   19\n\tstructType  20\n\tfieldType   21\n\t\/\/ 22 is slice of fieldType.\n\tmapType     23\n\nIn summary, a gob stream looks like\n\n\t((-type id, encoding of a wireType)* (type id, encoding of a value))*\n\nwhere * signifies zero or more repetitions and the type id of a value must\nbe predefined or be defined before the value in the stream.\n*\/\npackage gob\n\n\/*\nFor implementers and the curious, here is an encoded example.  Given\n\ttype Point {x, y int}\nand the value\n\tp := Point{22, 33}\nthe bytes transmitted that encode p will be:\n\t1f ff 81 03 01 01 05 50 6f 69 6e 74 01 ff 82 00 01 02 01 01 78\n\t01 04 00 01 01 79 01 04 00 00 00 07 ff 82 01 2c 01 42 00 07 ff\n\t82 01 2c 01 42 00\nThey are determined as follows.\n\nSince this is the first transmission of type Point, the type descriptor\nfor Point itself must be sent before the value.

When Encoder.Encode(v) is called, it makes sure there is an id assigned for\nthe type of v and all its elements and then it sends the pair (typeid, encoded-v)\nwhere typeid is the type id of the encoded type of v and encoded-v is the gob\nencoding of the value v.\n\nTo define a type, the encoder chooses an unused, positive type id and sends the\npair (-type id, encoded-type) where encoded-type is the gob encoding of a wireType\ndescription, constructed from these types:\n\n\ttype wireType struct {\n\t\ts structType\n\t}\n\ttype arrayType struct {\n\t\tcommonType\n\t\tElem typeId\n\t\tLen  int\n\t}\n\ttype commonType {\n\t\tname string \/\/ the name of the struct type\n\t\t_id  int    \/\/ the id of the type, repeated for so it's inside the type\n\t}\n\ttype sliceType struct {\n\t\tcommonType\n\t\tElem typeId\n\t}\n\ttype structType struct {\n\t\tcommonType\n\t\tfield []*fieldType \/\/ the fields of the struct.\n\t}\n\ttype fieldType struct {\n\t\tname string \/\/ the name of the field.\n\t\tid   int    \/\/ the type id of the field, which must be already defined\n\t}\n\ttype mapType struct {\n\t\tcommonType\n\t\tKey  typeId\n\t\tElem typeId\n\t}\n\nIf there are nested type ids, the types for all inner type ids must be defined\nbefore the top-level type id is used to describe an encoded-v.\n\nFor simplicity in setup, the connection is defined to understand these types a\npriori, as well as the basic gob types int, uint, etc.  Their ids are:\n\n\tbool        1\n\tint         2\n\tuint        3\n\tfloat       4\n\t[]byte      5\n\tstring      6\n\tcomplex     7\n\tinterface   8\n\t\/\/ gap for reserved ids.\n\twireType    16\n\tarrayType   17\n\tcommonType  18\n\tsliceType   19\n\tstructType  20\n\tfieldType   21\n\t\/\/ 22 is slice of fieldType.\n\tmapType     23\n\nIn summary, a gob stream looks like\n\n\t((-type id, encoding of a wireType)* (type id, encoding of a value))*\n\nwhere * signifies zero or more repetitions and the type id of a value must\nbe predefined or be defined before the value in the stream.\n*\/\npackage gob\n\n\/*\nFor implementers and the curious, here is an encoded example.

Attempting\nto encode a value that contains one will fail.\n\nThe rest of this comment documents the encoding, details that are not important\nfor most users.  Details are presented bottom-up.\n\nAn unsigned integer is sent one of two ways.  If it is less than 128, it is sent\nas a byte with that value.  Otherwise it is sent as a minimal-length big-endian\n(high byte first) byte stream holding the value, preceded by one byte holding the\nbyte count, negated.  Thus 0 is transmitted as (00), 7 is transmitted as (07) and\n256 is transmitted as (FE 01 00).\n\nA boolean is encoded within an unsigned integer: 0 for false, 1 for true.\n\nA signed integer, i, is encoded within an unsigned integer, u.  Within u, bits 1\nupward contain the value; bit 0 says whether they should be complemented upon\nreceipt.  The encode algorithm looks like this:\n\n\tuint u;\n\tif i < 0 {\n\t\tu = (^i << 1) | 1\t\/\/ complement i, bit 0 is 1\n\t} else {\n\t\tu = (i << 1)\t\/\/ do not complement i, bit 0 is 0\n\t}\n\tencodeUnsigned(u)\n\nThe low bit is therefore analogous to a sign bit, but making it the complement bit\ninstead guarantees that the largest negative integer is not a special case.  For\nexample, -129=^128=(^256>>1) encodes as (FE 01 01).\n\nFloating-point numbers are always sent as a representation of a float64 value.\nThat value is converted to a uint64 using math.Float64bits.  The uint64 is then\nbyte-reversed and sent as a regular unsigned integer.  The byte-reversal means the\nexponent and high-precision part of the mantissa go first.  Since the low bits are\noften zero, this can save encoding bytes.  For instance, 17.0 is encoded in only\nthree bytes (FE 31 40).\n\nStrings and slices of bytes are sent as an unsigned count followed by that many\nuninterpreted bytes of the value.\n\nAll other slices and arrays are sent as an unsigned count followed by that many\nelements using the standard gob encoding for their type, recursively.\n\nStructs are sent as a sequence of (field number, field value) pairs.  The field\nvalue is sent using the standard gob encoding for its type, recursively.  If a\nfield has the zero value for its type, it is omitted from the transmission.  The\nfield number is defined by the type of the encoded struct: the first field of the\nencoded type is field 0, the second is field 1, etc.  When encoding a value, the\nfield numbers are delta encoded for efficiency and the fields are always sent in\norder of increasing field number; the deltas are therefore unsigned.  The\ninitialization for the delta encoding sets the field number to -1, so an unsigned\ninteger field 0 with value 7 is transmitted as unsigned delta = 1, unsigned value\n= 7 or (01 07).  Finally, after all the fields have been sent a terminating mark\ndenotes the end of the struct.  That mark is a delta=0 value, which has\nrepresentation (00).\n\nInterface types are not checked for compatibility; all interface types are\ntreated, for transmission, as members of a single \"interface\" type, analogous to\nint or []byte - in effect they're all treated as interface{}.  Interface values\nare transmitted as a string identifying the concrete type being sent (a name\nthat must be pre-defined by calling Register()), followed by the usual encoding\nof concrete (dynamic) value stored in the interface value.  (A nil interface\nvalue is identified by the empty string and transmits no value.) Upon receipt,\nthe decoder verifies that the unpacked concrete item satisfies the interface of\nthe receiving variable.\n\nThe representation of types is described below.

The uint64 is then\nbyte-reversed and sent as a regular unsigned integer.  The byte-reversal means the\nexponent and high-precision part of the mantissa go first.  Since the low bits are\noften zero, this can save encoding bytes.  For instance, 17.0 is encoded in only\nthree bytes (FE 31 40).\n\nStrings and slices of bytes are sent as an unsigned count followed by that many\nuninterpreted bytes of the value.\n\nAll other slices and arrays are sent as an unsigned count followed by that many\nelements using the standard gob encoding for their type, recursively.\n\nStructs are sent as a sequence of (field number, field value) pairs.  The field\nvalue is sent using the standard gob encoding for its type, recursively.  If a\nfield has the zero value for its type, it is omitted from the transmission.  The\nfield number is defined by the type of the encoded struct: the first field of the\nencoded type is field 0, the second is field 1, etc.  When encoding a value, the\nfield numbers are delta encoded for efficiency and the fields are always sent in\norder of increasing field number; the deltas are therefore unsigned.  The\ninitialization for the delta encoding sets the field number to -1, so an unsigned\ninteger field 0 with value 7 is transmitted as unsigned delta = 1, unsigned value\n= 7 or (01 07).  Finally, after all the fields have been sent a terminating mark\ndenotes the end of the struct.  That mark is a delta=0 value, which has\nrepresentation (00).\n\nInterface types are not checked for compatibility; all interface types are\ntreated, for transmission, as members of a single \"interface\" type, analogous to\nint or []byte - in effect they're all treated as interface{}.  Interface values\nare transmitted as a string identifying the concrete type being sent (a name\nthat must be pre-defined by calling Register), followed by a byte count of the\nlength of the following data (so the value can be skipped if it cannot be\nstored), followed by the usual encoding of concrete (dynamic) value stored in\nthe interface value.  (A nil interface value is identified by the empty string\nand transmits a zero-length value.) Upon receipt, the decoder verifies that the\nunpacked concrete item satisfies the interface of the receiving variable.\n\nThe representation of types is described below.  When a type is defined on a given\nconnection between an Encoder and Decoder, it is assigned a signed integer type\nid.  When Encoder.Encode(v) is called, it makes sure there is an id assigned for\nthe type of v and all its elements and then it sends the pair (typeid, encoded-v)\nwhere typeid is the type id of the encoded type of v and encoded-v is the gob\nencoding of the value v.\n\nTo define a type, the encoder chooses an unused, positive type id and sends the\npair (-type id, encoded-type) where encoded-type is the gob encoding of a wireType\ndescription, constructed from these types:\n\n\ttype wireType struct {\n\t\ts structType\n\t}\n\ttype arrayType struct {\n\t\tcommonType\n\t\tElem typeId\n\t\tLen  int\n\t}\n\ttype commonType {\n\t\tname string \/\/ the name of the struct type\n\t\t_id  int    \/\/ the id of the type, repeated for so it's inside the type\n\t}\n\ttype sliceType struct {\n\t\tcommonType\n\t\tElem typeId\n\t}\n\ttype structType struct {\n\t\tcommonType\n\t\tfield []*fieldType \/\/ the fields of the struct.\n\t}\n\ttype fieldType struct {\n\t\tname string \/\/ the name of the field.\n\t\tid   int    \/\/ the type id of the field, which must be already defined\n\t}\n\ttype mapType struct {\n\t\tcommonType\n\t\tKey  typeId\n\t\tElem typeId\n\t}\n\nIf there are nested type ids, the types for all inner type ids must be defined\nbefore the top-level type id is used to describe an encoded-v.\n\nFor simplicity in setup, the connection is defined to understand these types a\npriori, as well as the basic gob types int, uint, etc.  Their ids are:\n\n\tbool        1\n\tint         2\n\tuint        3\n\tfloat       4\n\t[]byte      5\n\tstring      6\n\tcomplex     7\n\tinterface   8\n\t\/\/ gap for reserved ids.\n\twireType    16\n\tarrayType   17\n\tcommonType  18\n\tsliceType   19\n\tstructType  20\n\tfieldType   21\n\t\/\/ 22 is slice of fieldType.\n\tmapType     23\n\nIn summary, a gob stream looks like\n\n\t((-type id, encoding of a wireType)* (type id, encoding of a value))*\n\nwhere * signifies zero or more repetitions and the type id of a value must\nbe predefined or be defined before the value in the stream.\n*\/\npackage gob\n\n\/*\nFor implementers and the curious, here is an encoded example.  Given\n\ttype Point struct {x, y int}\nand the value\n\tp := Point{22, 33}\nthe bytes transmitted that encode p will be:\n\t1f ff 81 03 01 01 05 50 6f 69 6e 74 01 ff 82 00\n\t01 02 01 01 78 01 04 00 01 01 79 01 04 00 00 00\n\t07 ff 82 01 2c 01 42 00\nThey are determined as follows.\n\nSince this is the first transmission of type Point, the type descriptor\nfor Point itself must be sent before the value.  This is the first type\nwe've sent on this Encoder, so it has type id 65 (0 through 64 are\nreserved).\n\n\t1f\t\/\/ This item (a type descriptor) is 31 bytes long.\n\tff 81\t\/\/ The negative of the id for the type we're defining, -65.\n\t\t\/\/ This is one byte (indicated by FF = -1) followed by\n\t\t\/\/ ^-65<<1 | 1.  The low 1 bit signals to complement the\n\t\t\/\/ rest upon receipt.\n\n\t\/\/ Now we send a type descriptor, which is itself a struct (wireType).\n\t\/\/ The type of wireType itself is known (it's built in, as is the type of\n\t\/\/ all its components), so we just need to send a *value* of type wireType\n\t\/\/ that represents type \"Point\".\n\t\/\/ Here starts the encoding of that value.\n\t\/\/ Set the field number implicitly to -1; this is done at the beginning\n\t\/\/ of every struct, including nested structs.\n\t03\t\/\/ Add 3 to field number; now 2 (wireType.structType; this is a struct).\n\t\t\/\/ structType starts with an embedded commonType, which appears\n\t\t\/\/ as a regular structure here too.\n\t01\t\/\/ add 1 to field number (now 0); start of embedded commonType.\n\t01\t\/\/ add 1 to field number (now 0, the name of the type)\n\t05\t\/\/ string is (unsigned) 5 bytes long\n\t50 6f 69 6e 74\t\/\/ wireType.structType.commonType.name = \"Point\"\n\t01\t\/\/ add 1 to field number (now 1, the id of the type)\n\tff 82\t\/\/ wireType.structType.commonType._id = 65\n\t00\t\/\/ end of embedded wiretype.structType.commonType struct\n\t01\t\/\/ add 1 to field number (now 1, the field array in wireType.structType)\n\t02\t\/\/ There are two fields in the type (len(structType.field))\n\t01\t\/\/ Start of first field structure; add 1 to get field number 0: field[0].name\n\t01\t\/\/ 1 byte\n\t78\t\/\/ structType.field[0].name = \"x\"\n\t01\t\/\/ Add 1 to get field number 1: field[0].id\n\t04\t\/\/ structType.field[0].typeId is 2 (signed int).\n\t00\t\/\/ End of structType.field[0]; start structType.field[1]; set field number to -1.\n\t01\t\/\/ Add 1 to get field number 0: field[1].name\n\t01\t\/\/ 1 byte\n\t79\t\/\/ structType.field[1].name = \"y\"\n\t01\t\/\/ Add 1 to get field number 1: field[0].id\n\t04\t\/\/ struct.Type.field[1].typeId is 2 (signed int).\n\t00\t\/\/ End of structType.field[1]; end of structType.field.\n\t00\t\/\/ end of wireType.structType structure\n\t00\t\/\/ end of wireType structure\n\nNow we can send the Point value.  Again the field number resets to -1:\n\n\t07\t\/\/ this value is 7 bytes long\n\tff 82\t\/\/ the type number, 65 (1 byte (-FF) followed by 65<<1)\n\t01\t\/\/ add one to field number, yielding field 0\n\t2c\t\/\/ encoding of signed \"22\" (0x22 = 44 = 22<<1); Point.x = 22\n\t01\t\/\/ add one to field number, yielding field 1\n\t42\t\/\/ encoding of signed \"33\" (0x42 = 66 = 33<<1); Point.y = 33\n\t00\t\/\/ end of structure\n\nThe type encoding is long and fairly intricate but we send it only once.\nIf p is transmitted a second time, the type is already known so the\noutput will be just:\n\n\t07 ff 82 01 2c 01 42 00\n\nA single non-struct value at top level is transmitted like a field with\ndelta tag 0.  For instance, a signed integer with value 3 presented as\nthe argument to Encode will emit:\n\n\t03 04 00 06\n\nWhich represents:\n\n\t03\t\/\/ this value is 3 bytes long\n\t04\t\/\/ the type number, 2, represents an integer\n\t00\t\/\/ tag delta 0\n\t06\t\/\/ value 3\n\n*\/\n<|endoftext|>"}

If not, see <https:\/\/www.gnu.org\/licenses\/>.\n*\/\n\n\/\/ Package httpgzip implements an http.Handler wrapper adding gzip\n\/\/ compression for appropriate requests.\n\/\/\n\/\/ It attempts to properly parse the request's Accept-Encoding header\n\/\/ according to RFC 2616 and does not do a simple string search for\n\/\/ \"gzip\" (which will fail to do the correct thing for values such as\n\/\/ \"*\" or \"identity,gzip;q=0\"). It will serve either gzip or identity\n\/\/ content codings, or return 406 Not Acceptable status if it can do\n\/\/ neither.\n\/\/\n\/\/ It works correctly with handlers which honour Range request headers\n\/\/ (such as http.FileServer) by removing the Range header for requests\n\/\/ which prefer gzip encoding. This is necessary since Range requests\n\/\/ apply to the gzipped content but the wrapped handler is not aware\n\/\/ of the compression when it writes byte ranges. The Accept-Ranges\n\/\/ header is also stripped from corresponding responses.\n\/\/\n\/\/ A Content-Type header is set using http.DetectContentType if it is\n\/\/ not set by the wrapped handler.\npackage httpgzip \/\/ import \"xi2.org\/x\/httpgzip\"\n\nimport (\n\t\"bytes\"\n\t\"compress\/gzip\"\n\t\"mime\"\n\t\"net\/http\"\n\t\"strconv\"\n\t\"strings\"\n\t\"sync\"\n)\n\n\/\/ DefaultContentTypes is the default list of content types for which\n\/\/ a Handler considers gzip compression. This list originates from the\n\/\/ file compression.conf within the Apache configuration found at\n\/\/ https:\/\/html5boilerplate.com\/.\nvar DefaultContentTypes = []string{\n\t\"application\/atom+xml\",\n\t\"application\/javascript\",\n\t\"application\/json\",\n\t\"application\/ld+json\",\n\t\"application\/manifest+json\",\n\t\"application\/rdf+xml\",\n\t\"application\/rss+xml\",\n\t\"application\/schema+json\",\n\t\"application\/vnd.geo+json\",\n\t\"application\/vnd.ms-fontobject\",\n\t\"application\/x-font-ttf\",\n\t\"application\/x-javascript\",\n\t\"application\/x-web-app-manifest+json\",\n\t\"application\/xhtml+xml\",\n\t\"application\/xml\",\n\t\"font\/eot\",\n\t\"font\/opentype\",\n\t\"image\/bmp\",\n\t\"image\/svg+xml\",\n\t\"image\/vnd.microsoft.icon\",\n\t\"image\/x-icon\",\n\t\"text\/cache-manifest\",\n\t\"text\/css\",\n\t\"text\/html\",\n\t\"text\/javascript\",\n\t\"text\/plain\",\n\t\"text\/vcard\",\n\t\"text\/vnd.rim.location.xloc\",\n\t\"text\/vtt\",\n\t\"text\/x-component\",\n\t\"text\/x-cross-domain-policy\",\n\t\"text\/xml\",\n}\n\nvar gzipWriterPool = sync.Pool{\n\tNew: func() interface{} { return gzip.NewWriter(nil) },\n}\n\nvar gzipBufPool = sync.Pool{\n\tNew: func() interface{} { return new(bytes.Buffer) },\n}\n\n\/\/ A gzipResponseWriter is a modified http.ResponseWriter. It adds\n\/\/ gzip compression to certain responses, and there are two cases\n\/\/ where this is done. Case 1 is when encs only allows gzip encoding\n\/\/ and forbids identity.

This is necessary since Range requests\n\/\/ apply to the gzipped content but the wrapped handler is not aware\n\/\/ of the compression when it writes byte ranges. The Accept-Ranges\n\/\/ header is also stripped from corresponding responses.\n\/\/\n\/\/ For requests which prefer gzip encoding a Content-Type header is\n\/\/ set using http.DetectContentType if it is not set by the wrapped\n\/\/ handler.\npackage httpgzip \/\/ import \"xi2.org\/x\/httpgzip\"\n\nimport (\n\t\"bytes\"\n\t\"compress\/gzip\"\n\t\"mime\"\n\t\"net\/http\"\n\t\"strconv\"\n\t\"strings\"\n\t\"sync\"\n)\n\n\/\/ DefaultContentTypes is the default list of content types for which\n\/\/ a Handler considers gzip compression.

A Propagate entry from A\n\/\/ (src) to B (dst) indicates that the type\/value of A propagates to B. In Tern,\n\/\/ this is indicated by A having a \"fwd\" property whose value is an array that\n\/\/ includes B.\n\/\/\n\/\/\n\/\/ ## Motivation & example\n\/\/\n\/\/ For example, consider the following JavaScript code:\n\/\/\n\/\/   var a = Foo;\n\/\/   var b = a;\n\/\/\n\/\/ Foo, a, and b are each their own symbol. We could resolve all of them to the\n\/\/ symbol of their original type (perhaps Foo), but there are occasions when you\n\/\/ do want to see only the definition of a or b and examples thereof. Therefore,\n\/\/ we need to represent them as distinct symbols.\n\/\/\n\/\/ Even though Foo, a, and b are distinct symbols, there are propagation\n\/\/ relationships between them that are important to represent. The type of Foo\n\/\/ propagates to both a and b, and the type of a propagates to b. In this case,\n\/\/ we would have 3 Propagates: Propagate{Src: \"Foo\", Dst: \"a\"}, Propagate{Src:\n\/\/ \"Foo\", Dst: \"b\"}, and Propagate{Src: \"a\", Dst: \"b\"}. (The propagation\n\/\/ relationships could be described by just the first and last Propagates, but\n\/\/ we explicitly include all paths as a denormalization optimization to avoid\n\/\/ requiring an unbounded number of DB queries to determine which symbols a type\n\/\/ propagates to or from.)\n\/\/\n\/\/\n\/\/ ## Directionality\n\/\/\n\/\/ Propagation is unidirectional, in the general case. In the example above, if\n\/\/ Foo referred to a JavaScript object and if the code were evaluated, any\n\/\/ *runtime* type changes (e.g., setting a property) on Foo, a, and b would be\n\/\/ reflected on all of the others.

A Propagate entry from A\n\/\/ (src) to B (dst) indicates that the type\/value of A propagates to B. In Tern,\n\/\/ this is indicated by A having a \"fwd\" property whose value is an array that\n\/\/ includes B.\n\/\/\n\/\/\n\/\/ ## Motivation & example\n\/\/\n\/\/ For example, consider the following JavaScript code:\n\/\/\n\/\/   var a = Foo;\n\/\/   var b = a;\n\/\/\n\/\/ Foo, a, and b are each their own symbol. We could resolve all of them to the\n\/\/ symbol of their original type (perhaps Foo), but there are occasions when you\n\/\/ do want to see only the definition of a or b and examples thereof. Therefore,\n\/\/ we need to represent them as distinct symbols.\n\/\/\n\/\/ Even though Foo, a, and b are distinct symbols, there are propagation\n\/\/ relationships between them that are important to represent. The type of Foo\n\/\/ propagates to both a and b, and the type of a propagates to b. In this case,\n\/\/ we would have 3 Propagates: Propagate{Src: \"Foo\", Dst: \"a\"}, Propagate{Src:\n\/\/ \"Foo\", Dst: \"b\"}, and Propagate{Src: \"a\", Dst: \"b\"}. (The propagation\n\/\/ relationships could be described by just the first and last Propagates, but\n\/\/ we explicitly include all paths as a denormalization optimization to avoid\n\/\/ requiring an unbounded number of DB queries to determine which symbols a type\n\/\/ propagates to or from.)\n\/\/\n\/\/\n\/\/ ## Directionality\n\/\/\n\/\/ Propagation is unidirectional, in the general case. In the example above, if\n\/\/ Foo referred to a JavaScript object and if the code were evaluated, any\n\/\/ *runtime* type changes (e.g., setting a property) on Foo, a, and b would be\n\/\/ reflected on all of the others. But this doesn't hold for static analysis;\n\/\/ it's not always true that if a property \"a.x\" or \"b.x\" exists, then \"Foo.x\"\n\/\/ exists. The simplest example is when Foo is an external definition. Perhaps\n\/\/ this example file (which uses Foo as a library) modifies Foo to add a new\n\/\/ property, but other libraries that use Foo would never see that property\n\/\/ because they wouldn't be executed in the same context as this example file.\n\/\/ So, in general, we cannot say that Foo receives all types applied to symbols\n\/\/ that Foo propagates to.\n\/\/\n\/\/\n\/\/ ## Hypothetical Python example\n\/\/\n\/\/ Consider the following 2 Python files:\n\/\/\n\/\/   \"\"\"file1.py\"\"\"\n\/\/   class Foo(object): end\n\/\/\n\/\/   \"\"\"file2.py\"\"\"\n\/\/   from .file1 import Foo\n\/\/   Foo2 = Foo\n\/\/\n\/\/ In this example, there would be one Propagate: Propagate{Src: \"file1\/Foo\",\n\/\/ Dst: \"file2\/Foo2}.\ntype Propagate struct {\n\t\/\/ Src is the symbol whose type\/value is being propagated to the dst symbol.\n\tSrcRepo     repo.URI\n\tSrcPath     SymbolPath\n\tSrcUnit     string\n\tSrcUnitType string\n\n\t\/\/ Dst is the symbol that is receiving a propagated type\/value from the src symbol.\n\tDstRepo     repo.URI\n\tDstPath     SymbolPath\n\tDstUnit     string\n\tDstUnitType string\n}\n\nconst (\n\tConst   SymbolKind = \"const\"\n\tField              = \"field\"\n\tFunc               = \"func\"\n\tModule             = \"module\"\n\tPackage            = \"package\"\n\tType               = \"type\"\n\tVar                = \"var\"\n)\n\nvar AllSymbolKinds = []SymbolKind{Const, Field, Func, Module, Package, Type, Var}\n\n\/\/ Returns true iff k is a known symbol kind.\nfunc (k SymbolKind) Valid() bool {\n\tfor _, kk := range AllSymbolKinds {\n\t\tif k == kk {\n\t\t\treturn true\n\t\t}\n\t}\n\treturn false\n}\n\nfunc KindName(k string) string {\n\tif strings.HasSuffix(k, \"_module\") {\n\t\treturn \"module\"\n\t}\n\treturn strings.Replace(k, \"_\", \" \", -1)\n}\n\ntype ConstData struct {\n\tConstValue string\n}\n\n\/\/ SQL\n\nfunc (x SID) Value() (driver.Value, error) {\n\treturn int64(x), nil\n}\n\nfunc (x *SID) Scan(v interface{}) error {\n\tif data, ok := v.(int64); ok {\n\t\t*x = SID(data)\n\t\treturn nil\n\t}\n\treturn fmt.Errorf(\"%T.Scan failed: %v\", x, v)\n}\n\nfunc (x SymbolPath) Value() (driver.Value, error) {\n\treturn string(x), nil\n}\n\nfunc (x *SymbolPath) Scan(v interface{}) error {\n\tif data, ok := v.([]byte); ok {\n\t\t*x = SymbolPath(data)\n\t\treturn nil\n\t}\n\treturn fmt.Errorf(\"%T.Scan failed: %v\", x, v)\n}\n\nfunc (x SymbolKind) Value() (driver.Value, error) {\n\treturn string(x), nil\n}\n\nfunc (x *SymbolKind) Scan(v interface{}) error {\n\tif data, ok := v.([]byte); ok {\n\t\t*x = SymbolKind(data)\n\t\treturn nil\n\t}\n\treturn fmt.Errorf(\"%T.Scan failed: %v\", x, v)\n}\n\nfunc (x *ConstData) Value() (driver.Value, error) {\n\tif x == nil {\n\t\treturn nil, nil\n\t}\n\treturn json.Marshal(x)\n}\n\nfunc (x *ConstData) Scan(v interface{}) error {\n\tif data, ok := v.([]byte); ok {\n\t\treturn json.Unmarshal(data, x)\n\t}\n\treturn fmt.Errorf(\"%T.Scan failed: %v\", x, v)\n}\n\n\/\/ Debugging\n\nfunc (x Symbol) String() string {\n\ts, _ := json.Marshal(x)\n\treturn string(s)\n}\n\n\/\/ Sorting\n\ntype Symbols []*Symbol\n\nfunc (vs Symbols) Len() int           { return len(vs) }\nfunc (vs Symbols) Swap(i, j int)      { vs[i], vs[j] = vs[j], vs[i] }\nfunc (vs Symbols) Less(i, j int) bool { return vs[i].sortKey() < vs[j].sortKey() }\n\nfunc (syms Symbols) Keys() (keys []SymbolKey) {\n\tkeys = make([]SymbolKey, len(syms))\n\tfor i, sym := range syms {\n\t\tkeys[i] = sym.SymbolKey\n\t}\n\treturn\n}\n\nfunc (syms Symbols) SIDs() (ids []SID) {\n\tids = make([]SID, len(syms))\n\tfor i, sym := range syms {\n\t\tids[i] = sym.SID\n\t}\n\treturn\n}\n\nfunc ParseSIDs(sidstrs []string) (sids []SID) {\n\tsids = make([]SID, len(sidstrs))\n\tfor i, sidstr := range sidstrs {\n\t\tsid, err := strconv.Atoi(sidstr)\n\t\tif err == nil {\n\t\t\tsids[i] = SID(sid)\n\t\t}\n\t}\n\treturn\n}\n<|endoftext|>"}

shared data (such as roles, issuers, keys, and configuration)\n * are always forwarded to the Primary cluster's active node to write and send the key\n * material\/config globally across all clusters. Reads should be handled locally, to give a\n * sense of where this cluster's replication state is at.\n *\n * CRL\/Revocation and Fetch Certificate APIs are handled by the active node within the cluster\n * they originate. This means, if a request comes into a performance secondary cluster, the writes\n * will be forwarded to that cluster's active node and not go all the way up to the performance primary's\n * active node.\n *\n * If a certificate issue request has a role in which no_store is set to true, that node itself\n * will issue the certificate and not forward the request to the active node, as this does not\n * need to write to storage.\n *\n * Following the same pattern, if a managed key is involved to sign an issued certificate request\n * and the local node does not have access for some reason to it, the request will be forwarded to\n * the active node within the cluster only.\n *\n * To make sense of what goes where the following bits need to be analyzed within the codebase.\n *\n * 1. The backend LocalStorage paths determine what storage paths will remain within a\n *    cluster and not be forwarded to a performance primary\n * 2. Within each path's OperationHandler definition, check to see if ForwardPerformanceStandby &\n *    ForwardPerformanceSecondary flags are set to short-circuit the request to a given active node\n * 3. Within the managed key util class in pki, an initialization failure could cause the request\n *    to be forwarded to an active node if not already on it.\n *\/\n\n\/\/ Factory creates a new backend

For more information on installing and running ciao-launcher\n\/\/ see https:\/\/github.com\/01org\/ciao\/blob\/master\/ciao-launcher\/README.md\n\/\/ for more information.\n\/\/\n\/\/ Introduction\n\/\/\n\/\/ ciao-launcher tries to take advantage of Go's concurrency support as much as\n\/\/ possible.  The intention here is that most of the work involved in launching\n\/\/ and manipulating VMs is mostly self contained and IO bound and so should in\n\/\/ theory lend itself well to a concurrent design.  As a consequence, ciao-launcher\n\/\/ is highly concurrent and performant.  The concurrent nature\n\/\/ of ciao-launcher can make it a little difficult to understand for new comers,\n\/\/ so here are a few notes on its design.  ciao-launcher can be thought of as a\n\/\/ collection of distinct go routines.  These notes explain what these go\n\/\/ routines are for and how they communicate.\n\/\/\n\/\/ Main\n\/\/\n\/\/ Main is the go routine that starts when ciao-launcher is itself launched.  The code\n\/\/ for this is in main.go.  It parses the command line parameters, initialises\n\/\/ networking, ensures that no other instance of ciao-launcher are running and then\n\/\/ starts the server go routine.  Having done all this, the main go routine waits\n\/\/ for a signal, e.g., SIGTERM, from the OS to quit.  When this signal is retrieved\n\/\/ it instructs all child go routines to quit and waits for their exit.  Note that\n\/\/ it only waits for 1 second.  If all child go routines have failed to exit in 1\n\/\/ second, ciao-launcher panics.  The panic is useful as it prints the stack trace of\n\/\/ all the running go routines, so you can see which ones are blocked.  At least\n\/\/ this was the intention.  The default behaviour of the go runtime has changed in\n\/\/ this regard in 1.6 so a small code change is required, but you get the idea, I\n\/\/ hope.\n\/\/\n\/\/ The Server go routine\n\/\/\n\/\/ Manages the connection to the SSNTP server and pre-processes all commands\n\/\/ received from this server. The code for this go routine is also in main.go, at\n\/\/ least for the time being.  ciao-Launcher\n\/\/ establishes a connection to the ssntp server via the ssntp.Dial command.  This\n\/\/ creates a separate go routine, managed by the ssntp library.  Any subsequent\n\/\/ ssntp events that occur are handled by the ciao-launcher function CommandNotify.\n\/\/ CommandNotify is called in the context of the ssntp go routine.  To avoid\n\/\/ blocking this go routine, ciao-launcher parses the YAML associated with the command,\n\/\/ sends a newly created internal command down a channel to the server go routine\n\/\/ and returns.  The command is then processed further in the server go routine.\n\/\/\n\/\/ Most commands are operations on instances, e.g., create a new instance, restart\n\/\/ an instance, and are ultimately processed by a go routine dedicated to the\n\/\/ particular instance to which they pertain.  These instance go routines are\n\/\/ managed by another go routine called the overseer which will be discussed in\n\/\/ more detail below.  Before the server go routine can forward a command to the\n\/\/ appropriate go routine it needs to ask the overseer for a channel which can be\n\/\/ used to communicate with the relevant instance go routine.  This is done by\n\/\/ sending an ovsAddCmd or an ovsGetCmd to the overseer via the overseer channel,\n\/\/ ovsCh.  ovsAddCmd is used when starting a new instance.  ovsGetCmd is used to\n\/\/ process all other commands.\n\/\/\n\/\/ The overseer go routine is started by the server go routine.  When the server\n\/\/ go routine is asked to exit by the main go routine, i.e., main go routine\n\/\/ closes the doneCh channel, the server go routine closes the channel it uses\n\/\/ to communicate with the overseer.  This instructs the overseer to close,\n\/\/ which it does after all the instance go routines it manages have in turn\n\/\/ exited.  The server go routine waits for the overseer to exit before\n\/\/ terminating.\n\/\/\n\/\/ The Overseer\n\/\/\n\/\/ The overseer is a go routine that serves three main purposes.\n\/\/\n\/\/  1.  It manages instance go routines that themselves manage individual vms.\n\/\/  2.  It collects statistics about the node and the VMs it hosts and\n\/\/      tranmits these periodically to the ssntp server via the STATS and\n\/\/      STATUS commands.\n\/\/  3.  It Rediscovers and reconnects to existing instances when ciao-launcher is started.\n\/\/ Overseer launches new instances via the startInstance function from instance.go.\n\/\/ This function starts a new go routine for that instance and returns a channel\n\/\/ through which commands can be sent to the instance.  The overseer itself does\n\/\/ not send commands down this channel.  It cannot as this would lead to deadlock.\n\/\/ Instead it makes this channel available to the server go routine when it is\n\/\/ requested via the ovsAddCmd or the ovsGetCmd commands.\n\/\/\n\/\/ The overseer passes each instance go routine a reference to the a single\n\/\/ channel, childDoneCh.  This channel is closed when the overseer starts shutting\n\/\/ down.  Closing this channel serves as a broadcast notification to each instance\n\/\/ go routine, indicating that they need to shutdown.  The overseer waits until all\n\/\/ instance go routines have shut down before exiting.  This is achieved via a wait\n\/\/ group called chilWg.\n\/\/\n\/\/ The overseer maintains a map of information about each instance called\n\/\/ instances.  The map is indexed by the uuid of instances.  It contains\n\/\/ information about the instances, namely their running state and their resource\n\/\/ usage.  This information is used when sending STATs and STATUS commands.\n\/\/\n\/\/ Information about the instances ultimately comes from the instance go routines.\n\/\/ However, these go routines cannot access the overseer's instance map directly.\n\/\/ To update it they send commands down a channel, which the overseer passes to\n\/\/ startInstance, for example, ovsStatsUpdateCmd or ovsStateChange.  The overseer\n\/\/ processes these commands in the processCommand function.\n\/\/\n\/\/ The Instance Go routines\n\/\/\n\/\/ ciao-launcher maintains one go routine per instance it manages.  These go routines\n\/\/ exist regardless of the state of the underlying instance, i.e., there is\n\/\/ generally one go routine running per instance, regardless of whether that\n\/\/ instance is pending, exited or running.\n\/\/\n\/\/ The instance go routines serve 3 main purposes:\n\/\/\n\/\/  1. They accept and process commands from the server go routine down their\n\/\/     command channel.  These commands typically come from the ssntp server,\n\/\/     although there are some occasions where the commands originate from inside\n\/\/     ciao-launcher itself.\n\/\/  2. They monitor the running state of VMs.\n\/\/  3. They manage the collection of instance statistics, which they report\n\/\/     to the overseer.\n\/\/\n\/\/ The nice thing about this design is that almost all instance related work can be\n\/\/ performed in parallel.  Stats can be computed for one instance at the same time\n\/\/ as a separate instance is being powered down.  ciao-Launcher can process any number\n\/\/ of commands to start new instances in parallel.  There is no locking required\n\/\/ apart from a synchronised access to the overseer map made by the server go\n\/\/ routine when the command is first received and a small check related to the\n\/\/ image from which the instance will be launched, in the case where instances are\n\/\/ being started.  An additional synchronisation point is required for docker\n\/\/ instances to ensure that the relevant docker network has been created\n\/\/ before the container.\n\/\/\n\/\/ Note that although commands submitted to different instances are in executed in\n\/\/ parallel, the instance go routines serialise commands issue against a single\n\/\/ instance.  This is necessary to avoid instance corruption.\n\/\/\n\/\/ Right now the command channels that the server go routine uses to send command\n\/\/ to instances are not buffered.  This might need to change as currently it could\n\/\/ be possible for a SSNTP server to kill ciao-launcher's parallelism by repetively\n\/\/ sending commands to the same instance over and over again.\n\/\/\n\/\/ The code for the instance go routines is in instance.go.  However, the code that\n\/\/ executes most of the commands has been placed in separate files named after the\n\/\/ commands themselves, e.g., start.go, delete.go, restart.go.  It should be noted\n\/\/ that the code in these files runs in the context of an instance go routine.\n\/\/ Finally, some of the code used to process instance commands is in payloads.go.\n\/\/ This is for legacy reasons and in the future this file will probably go away and\n\/\/ its contents will be redistributed.  It should not be assumed as of the time of\n\/\/ writing that all the code in payloads.go runs in an instance go routine.\n\/\/ payloads.go needs cleaning up (https:\/\/github.com\/01org\/ciao\/issues\/10).\n\/\/\n\/\/ The virtualizer\n\/\/\n\/\/ The instance go routines need to talk to qemu and docker to manage their VMs\n\/\/ and containers.  However, they do not do so directly.  Rather they do so via\n\/\/ a virtualizer interface.\n\/\/\n\/\/ The virtualizer interface is designed to isolate ciao-launcher, and in particular,\n\/\/ functions that run in the instance go routine, from the underlying virtualisation\n\/\/ technologies used to launch and manage VMs and containers.\n\/\/ All the methods on the virtualizer interface will be called serially by the instance\n\/\/ go routine.  Therefore there is no need to synchronised data between the virtualizers\n\/\/ methods.\n\/\/\n\/\/ qemu.go contains functions to start and stop a VM, to create a qcow2 image, to\n\/\/ collect statistics about the instance running in the hypervisor, such as its\n\/\/ memory and cpu usage, and to monitor the instance, i.e., to determine whether\n\/\/ the VM is actually running or not.\n\/\/\n\/\/ docker.go contains methods to manage docker containers.\n\/\/\n\/\/ For more information about the virtualizer API, please see the comments\n\/\/ in https:\/\/github.com\/01org\/ciao\/blob\/master\/ciao-launcher\/virtualizer.go\n\/\/\npackage main\n<commit_msg>ciao-launcher: doc grammar tweek<commit_after>\/*\n\/\/ Copyright (c) 2016 Intel Corporation\n\/\/\n\/\/ Licensed under the Apache License, Version 2.0 (the \"License\");\n\/\/ you may not use this file except in compliance with the License.\n\/\/ You may obtain a copy of the License at\n\/\/\n\/\/      http:\/\/www.apache.org\/licenses\/LICENSE-2.0\n\/\/\n\/\/ Unless required by applicable law or agreed to in writing, software\n\/\/ distributed under the License is distributed on an \"AS IS\" BASIS,\n\/\/ WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied.\n\/\/ See the License for the specific language governing permissions and\n\/\/ limitations under the License.\n*\/\n\n\/\/ ciao-launcher is an ssntp agent that runs on compute and network nodes.\n\/\/ Its primary purpose is to launch and manage containers and virtual\n\/\/ machines.

{"text":"<commit_before>\/*\nPackage sqlr is designed to reduce the effort required to implement\ncommon operations performed with SQL databases. It is intended for programmers\nwho are comfortable with writing SQL, but would like assistance with the\nsometimes tedious process of preparing SQL queries for tables that have a\nlarge number of columns, or have a variable number of input parameters.\n\nThis package is designed to work seamlessly with the standard library\n\"database\/sql\" package. It does not provide any layer on top of *sql.DB\nor *sql.Tx. If the calling program has a need to execute queries independently\nof this package, it can use \"database\/sql\" directly, or make use of any other\nthird party package that uses \"database\/sql\".\n\nThe following features are provided to simplify writing SQL database queries:\n - Prepare SQL from row structures\n - Autoincrement column values\n - Null columns\n - JSON columns\n - WHERE IN Clauses with multiple values\n - Code generation\n\nPrepare SQL from row structures\n\nPreparing SQL queries with many placeholder arguments is tedious and error-prone. The following\ninsert query has a dozen placeholders, and it is difficult to match up the columns with the\nplaceholders. It is not uncommon to have tables with many dozens of columns, at which point the\nprocess of preparing SQL queries using the standard library becomes extremely tiresome.\n insert into users(id,given_name,family_name,dob,ssn,street,locality,postcode,country,phone,mobile,fax)\n values(?,?,?,?,?,?,?,?,?,?,?,?)\nThis package uses reflection to simplify the construction of SQL statements for insert, update, delete\nand select queries. Supplementary information about each database column is stored as a structure tag\nin the associated field.\n type User struct {\n     ID          int       `sql:\"primary key\"`\n     GivenName   string\n     FamilyName  string\n     DOB         time.Time `sql:\"null\"`\n     SSN         string\n     Street      string\n     Locality    string\n     Postcode    string\n     Country     string\n     Phone       string    `sql:\"null\"`\n     Mobile      string    `sql:\"null\"`\n     Facsimile   string    `sql:\"fax null\"` \/\/ \"fax\" overrides the column name\n }\nThe calling program creates a schema, which describes rules for generating SQL statements. These\nrules include specifying the SQL dialect (eg MySQL, Posgres, SQLite) and the naming convention\nused to convert Go struct field names into column names (eg \"GivenName\" => \"given_name\"). The schema\nis usually created during program initialization.\n schema := NewSchema(\n   WithDialect(MySQL),\n   WithNamingConvention(SnakeCase),\n )\nOnce the schema has been defined and a database handle is available (eg *sql.DB, *sql.Tx), it is possible\nto create simple row insert\/update\/delete statements with minimal effort.\n var row User\n \/\/ ... populate row with data here and then ...\n\n \/\/ generates the correct SQL to insert a row into the users table\n rowsAffected, err := schema.Exec(db, row, \"insert into users({}) values({})\")\n\n \/\/ ... and then later on ...\n\n \/\/ generates the correct SQL to update a the matching row in the users table\n rowsAffected, err := schema.Exec(db, row, \"update users set {} where {}\")\nThe Exec method parses the SQL query and replaces occurrances of \"{}\" with the column names\nor placeholders that make sense for the SQL clause in which they occur.

If the schema had been setup for, say, a Postgres\ndialect, a generated query would look more like\n select \"id\",\"given_name\",\"family_name\",\"dob\",\"ssn\",\"street\",\"locality\",\"postcode\",\"country\",\n \"phone\",\"mobile\",\"fax\" from users where postcode=$1\nIt is an important point to note that this feature is not about writing the SQL for the programmer.\nRather it is \"filling in the blanks\" and allowing the programmer to specify as much of the\nSQL query as they want without having to write the tiresome bits.\n\nAutoincrement Column Values\n\nWhen inserting rows, if a column is defined as an autoincrement column, then the generated\nvalue will be retrieved from the database server, and the corresponding field in the row\nstructure will be updated.\n type Row {\n   ID   int    `sql:\"primary key autoincrement\"`\n   Name string\n }\n\n row := &Row{Name: \"some name\"}\n _, err := schema.Exec(db, row, \"insert into table_name({}) values({})\")\n if err != nil {\n   log.Fatal(err)\n }\n\n \/\/ row.ID will contain the auto-generated value\n fmt.Println(row.ID)\nThis feature only works with database drivers that support autoincrement columns. The Postgres\ndriver, in particular, does not support this feature.\n\nNull Columns\n\nMost SQL database tables have columns that are nullable, and it can be tiresome to always\nmap to pointer types of special nullable types such as sql.NullString. In many cases it is\nacceptable to map a database NULL value to the empty value for the corresponding Go struct\nfield. (NOTE: It is not always acceptable, but experience has shown that it is a common\nenough situation).\n\nWhere it is acceptable to map a NULL value to an empty value and vice-versa, the Go struct\nfield can be marked with the \"null\" keyword in the field's struct tag.\n type User struct {\n     ID       int     `sql:\"primary key\"`\n     Name     string\n     SpouseID int     `sql:\"null\"`\n     Phone    string  `sql:\"null\"`\n }\nIn the above example the `spouse_id` column can be null, but because all IDs are non-zero,\nit is unambiguous to map a database NULL to the zero value. Similarly, if the `phone` column\nis null it will be mapped to an empty string. An empty string in the Go struct field will\nbe mapped to NULL in the database.\n\nCare should be taken, because there are cases where an empty value and a database NULL are not\nthe same thing. There are many cases, however, where this feature can be applied, and result\nis simpler code that is easier to read.\n\nJSON Columns\n\nIt is not uncommon to serialize complex objects as JSON text for storage in an SQL database.\nNative support for JSON is available in some database servers: in partcular Postgres has\nexcellent support for JSON.\n\nIt is straightforward to use this package to serialize a structure field to JSON.\n type SomethingComplex struct {\n     Name       string\n     Values     []int\n     MoreValues map[string]float64\n     \/\/ ... and more fields here ...\n }\n\n type Row struct {\n     ID    int                `sql:\"primary key\"`\n     Name  string\n     Cmplx *SomethingComplex  `sql:\"json\"`\n }\nIn the example above the `Cmplx` field will be marshaled as JSON text when\nwriting to the database, and unmarshaled into the struct when reading from\nthe database.\n\nWHERE IN Clauses with Multiple Values\n\nWhile most SQL queries accept a fixed number of parameters, if the SQL query\ncontains a `WHERE IN` clause, it requires additional string manipulation to match\nthe number of placeholders in the query with args.\n\nThis package simplifies queries with a variable number of arguments. When processing\nan SQL query, it detects if any of the arguments are slices:\n \/\/ GetWidgets returns all the widgets associated with the supplied IDs.\n func GetWidgets(db *sql.DB, ids ...int) ([]*Widget, error) {\n     var rows []*Widget\n     _, err := schema.Select(db, &rows, `select {} from widgets where id in (?)`, ids)\n     if err != nil {\n       return nil, err\n     }\n     return widgets, nil\n }\nIn the above example, the number of placeholders (\"?\") in the query will be increased to\nmatch the number of values in the `ids` slice. The expansion logic can handle any mix of\nslice and scalar arguments.\n\nCode Generation\n\nThis package contains a code generation tool in the \".\/cmd\/sqlr-gen\" directory. It can\nbe quite useful to reduce the amount of code even further.\n\nPerformance and Caching\n\nThis package makes use of reflection in order to build the SQL that is sent\nto the database server, and this imposes a performance penalty. In order\nto reduce this overhead each schema instance caches queries generated.\nThe end result is that the performance of this package is close to the\nperformance of code that uses hand-constructed SQL queries to call\npackage \"database\/sql\" directly.\n\nSource Code\n\nMore information about this package can be found at https:\/\/github.com\/jjeffery\/sqlr.\n*\/\npackage sqlr\n<commit_msg>Minor doc changes<commit_after>\/*\nPackage sqlr is designed to reduce the effort required to implement\ncommon operations performed with SQL databases. It is intended for programmers\nwho are comfortable with writing SQL, but would like assistance with the\nsometimes tedious process of preparing SQL queries for tables that have a\nlarge number of columns, or have a variable number of input parameters.\n\nThis package is designed to work seamlessly with the standard library\n\"database\/sql\" package. It does not provide any layer on top of *sql.DB\nor *sql.Tx. If the calling program has a need to execute queries independently\nof this package, it can use \"database\/sql\" directly, or make use of any other\nthird party package that uses \"database\/sql\".\n\nThe following features are provided to simplify writing SQL database queries:\n - Prepare SQL from row structures\n - Autoincrement column values\n - Null columns\n - JSON columns\n - WHERE IN Clauses with multiple values\n - Code generation\n\nPrepare SQL from row structures\n\nPreparing SQL queries with many placeholder arguments is tedious and error-prone. The following\ninsert query has a dozen placeholders, and it is difficult to match up the columns with the\nplaceholders. It is not uncommon to have tables with many dozens of columns, at which point the\nprocess of preparing SQL queries using the standard library becomes extremely tiresome.\n insert into users(id,given_name,family_name,dob,ssn,street,locality,postcode,country,phone,mobile,fax)\n values(?,?,?,?,?,?,?,?,?,?,?,?)\nThis package uses reflection to simplify the construction of SQL statements for insert, update, delete\nand select queries.

These\nrules include specifying the SQL dialect (eg MySQL, Posgres, SQLite) and the naming convention\nused to convert Go struct field names into column names (eg \"GivenName\" => \"given_name\"). The schema\nis usually created during program initialization.\n schema := NewSchema(\n   WithDialect(MySQL),\n   WithNamingConvention(SnakeCase),\n )\nOnce the schema has been defined and a database handle is available (eg *sql.DB, *sql.Tx), it is possible\nto create simple row insert\/update\/delete statements with minimal effort.\n var row User\n \/\/ ... populate row with data here and then ...\n\n \/\/ generates the correct SQL to insert a row into the users table\n rowsAffected, err := schema.Exec(db, row, \"insert into users({}) values({})\")\n\n \/\/ ... and then later on ...\n\n \/\/ generates the correct SQL to update a the matching row in the users table\n rowsAffected, err := schema.Exec(db, row, \"update users set {} where {}\")\nThe Exec method parses the SQL query and replaces occurrances of \"{}\" with the column names\nor placeholders that make sense for the SQL clause in which they occur.

These fields should all have their datastore field marked as \"-\".\n\nExample, with kind User:\n\ttype User struct {\n\t\tId    string `datastore:\"-\" goon:\"id\"`\n\t\tRead  time.Time\n\t}\n\nExample, with kind U if _kind is the empty string:\n\ttype User struct {\n\t\t_kind string `goon:\"kind,U\"`\n\t\tId    string `datastore:\"-\" goon:\"id\"`\n\t\tRead  time.Time\n\t}\n\nTo override kind of a single entity to UserKind:\n\tu := User{_kind: \"UserKind\"}\n\nAn example with both parent and kind:\n\ttype UserData struct {\n\t\tId     string         `datastore:\"-\" goon:\"id\"`\n\t\t_kind  string         `goon:\"kind,UD\"`\n\t\tParent *datastore.Key `datastore:\"-\" goon:\"parent\"`\n\t\tData   []byte\n\t}\n\nFeatures\n\nDatastore interaction with: Get, GetMulti, Put, PutMulti, Delete, DeleteMulti, Queries.\n\nAll key-based operations backed by memory and memcache.\n\nPer-request, in-memory cache: fetch the same key twice, the second request is served from local memory.\n\nIntelligent multi support: running GetMulti correctly fetches from memory, then memcache, then the datastore; each tier only sends keys off to the next one if they were missing.\n\nMemcache variance: Goon limits the length of the memcache requests to minimize outliers\n\nTransactions use a separate context, but locally cache any results on success.\n\nAutomatic kind naming: struct names are inferred by reflection, removing the need to manually specify key kinds.\n\nSimpler API than appengine\/datastore.\n\nAPI comparison between goon and datastore\n\nput with incomplete key\n\ndatastore:\n\n\ttype Group struct {\n\t\tName string\n\t}\n\tc := appengine.NewContext(r)\n\tg := &Group{Name: \"name\"}\n\tk := datastore.NewIncompleteKey(c, \"Group\", nil)\n\terr := datastore.Put(c, k, g)\n\ngoon:\n\n\ttype Group struct {\n\t\tId   int64 `datastore:\"-\" goon:\"id\"`\n\t\tName string\n\t}\n\tn := goon.NewGoon(r)\n\tg := &Group{Name: \"name\"}\n\terr := n.Put(g)\n\nget with known key\n\ndatastore:\n\n\ttype Group struct {\n\t\tName string\n\t}\n\tc := appengine.NewContext(r)\n\tg := &Group{}\n\tk := datastore.NewKey(c, \"Group\", \"\", 1, nil)\n\terr := datastore.Get(c, k, g)\n\ngoon:\n\n\ttype Group struct {\n\t\tId   int64 `datastore:\"-\" goon:\"id\"`\n\t\tName string\n\t}\n\tn := goon.NewGoon(r)\n\tg := &Group{Id: 1}\n\terr := n.Get(g)\n\nMemcache variance:\n\tPut:\n\t\tMemcachePutTimeoutThreshold is the number of bytes at which the memcache timeout uses the large setting.\n\t\tMemcachePutTimeoutSmall is the amount of time to wait during memcache Put operations before aborting them and using the datastore.\n\t\tMemcachePutTimeoutLarge is the amount of time to wait for large memcache Put requests.\n\n\tGet:\n\t\tMemcacheGetTimeout is the amount of time to wait for all memcache Get requests\n\n\tNotes:\n\t\tThe default settings are in effect and used by goon but if you are seeing too many memcache timeout errors in your logs, you may want to bump up the times.\n\t\tConversely, if you're using github.com\/mjibson\/appstats and are seeing Memcache requests finishing routinely before the default values you can bump them down.\n\t\tFinally, if these are not good default values as thought, please open an issue.\n\n\tTo change defaults:\n\t\tpackage myapp\n\n\t\timport (\n\t\t\t\"github.com\/mjibson\/goon\"\n\t\t\t\"time\"\n\t\t)\n\n\t\tfunc init() {\n\t\t\tgoon.MemcachePutTimeoutThreshold = 1024 * 50 \/\/ 50k\n\t\t\tgoon.MemcachePutTimeoutSmall = time.Millisecond * 10\n\t\t}\n*\/\npackage goon\n<|endoftext|>"}

It assumes\n\/\/ that the incoming bytes represent UTF-8 encoded text consisting of\n\/\/ lines of tab-terminated \"cells\". Cells in adjacent lines constitute\n\/\/ a column. Writer rewrites the incoming text such that all cells in\n\/\/ a column have the same width; thus it effectively aligns cells. It\n\/\/ does this by adding padding where necessary. All characters (ASCII\n\/\/ or not) are assumed to be of the same width - this may not be true\n\/\/ for arbitrary UTF-8 characters visualized on the screen.\n\/\/\n\/\/ Note that any text at the end of a line that is not tab-terminated\n\/\/ is not a cell and does not enforce alignment of cells in adjacent\n\/\/ rows. To make it a cell it needs to be tab-terminated.

It spins up the key portions of the edgestack\n\/\/ control plane that contain the bulk of its business logic, but instead of requiring tests to feed\n\/\/ the business logic inputs via a real kubernetes or real consul deployment, inputs can be fed\n\/\/ directly into the business logic via the harness APIs. This is not only several orders of\n\/\/ magnitute faster, this also provides the author of the test perfect control over the ordering of\n\/\/ events.\nfunc TestFakeHello(t *testing.T) {\n\t\/\/ Use RunFake() to spin up the ambassador control plane with its inputs wired up to the Fake\n\t\/\/ APIs. This will automatically invoke the Setup() method for the Fake and also register the\n\t\/\/ Teardown() method with the Cleanup() hook of the supplied testing.T object.\n\tf := entrypoint.RunFake(t, entrypoint.FakeConfig{})\n\n\t\/\/ The Fake harness has a store for both kubernetes resources and consul endpoint data. We can\n\t\/\/ use the UpsertFile() to method to load as many resources as we would like. This is much like\n\t\/\/ doing a `kubectl apply` to a real kubernetes API server, however apply uses fancy merge\n\t\/\/ logic, whereas UpsertFile() does a simple Upsert operation. The `testdata\/FakeHello.yaml`\n\t\/\/ file has a single mapping named \"hello\".\n\tf.UpsertFile(\"testdata\/FakeHello.yaml\")\n\t\/\/ Initially the Fake harness is paused. This means we can make as many method calls as we want\n\t\/\/ to in order to set up our initial conditions, and no inputs will be fed into the control\n\t\/\/ plane. To feed inputs to the control plane, we can choose to either manually invoke the\n\t\/\/ Flush() method whenever we want to send the control plane inputs, or for convenience we can\n\t\/\/ enable AutoFlush so that inputs are set whenever we modify data that the control plane is\n\t\/\/ watching.\n\tf.AutoFlush(true)\n\n\t\/\/ Once the control plane has started processing inputs, we need some way to observe its\n\t\/\/ computation. The Fake harness provides two ways to do this. The GetSnapshot() method allows\n\t\/\/ us to observe the snapshots assembled by the watchers for further processing. The\n\t\/\/ GetEnvoyConfig() method allows us to observe the envoy configuration produced from a\n\t\/\/ snapshot. Both these methods take a predicate so the can search for a snapshot that satisifes\n\t\/\/ whatever conditions are being tested. This allows the test to verify that the correct\n\t\/\/ computation is occurring without being overly prescriptive about the exact number of\n\t\/\/ snapshots and\/or envoy configs that are produce to achieve a certain result.\n\tsnap := f.GetSnapshot(func(snap *snapshot.Snapshot) bool {\n\t\treturn len(snap.Kubernetes.Mappings) > 0\n\t})\n\t\/\/ Check that the snapshot contains the mapping from the file.\n\tassert.Equal(t, \"hello\", snap.Kubernetes.Mappings[0].Name)\n}\n\n\/\/ By default the Fake struct only invokes the first part of the pipeline that forms the control\n\/\/ plane. If you use the EnvoyConfig option you can run the rest of the control plane. There is also\n\/\/ a Timeout option that controls how long the harness waits for the desired Snapshot and\/or\n\/\/ EnvoyConfig to come along.\n\/\/\n\/\/ Note that this test depends on diagd being in your path. If diagd is not available, the test will\n\/\/ be skipped.\nfunc TestFakeHelloWithEnvoyConfig(t *testing.T) {\n\t\/\/ Use the FakeConfig parameter to conigure the Fake harness.

Host-specific patterns take precedence over general\n\/\/ patterns, so that a handler might register for the two patterns \"\/codesearch\"\n\/\/ and \"codesearch.google.com\/\" without also taking over requests for\n\/\/ \"http:\/\/www.google.com\/\".\n\/\/\n\/\/ ServeMux also takes care of sanitizing the URL request path and the Host\n\/\/ header, stripping the port number and redirecting any request containing . or\n\/\/ .. elements or repeated slashes to an equivalent, cleaner URL.\n\/\/\n\/\/ Multiple handlers can be registered for a single pattern, as long as they\n\/\/ handle different HTTP methods.\ntype ServeMux struct {\n\tmux *http.ServeMux\n}\n\nfunc registerHandlers(mux *http.ServeMux, handlers map[string]map[string]handlerConfig, methodNotAllowed handlerConfig) {\n\tfor pattern, handlersPerMethod := range handlers {\n\t\thandlersPerMethod := handlersPerMethod\n\t\tmux.HandleFunc(pattern, func(w http.ResponseWriter, r *http.Request) {\n\t\t\tcfg, ok := handlersPerMethod[r.Method]\n\t\t\tif !ok {\n\t\t\t\tcfg = methodNotAllowed\n\t\t\t}\n\t\t\tprocessRequest(cfg, w, r)\n\t\t})\n\t}\n}\n\n\/\/ ServeHTTP dispatches the request to the handler whose method matches the\n\/\/ incoming request and whose pattern most closely matches the request URL.\n\/\/\n\/\/  For each incoming request:\n\/\/  - [Before Phase] Interceptor.Before methods are called for every installed\n\/\/    interceptor, until an interceptor writes to a ResponseWriter (including\n\/\/    errors) or panics,\n\/\/  - the handler is called after a [Before Phase] if no writes or panics occured,\n\/\/  - the handler triggers the [Commit Phase] by writing to the ResponseWriter,\n\/\/  - [Commit Phase] Interceptor.Commit methods run for every interceptor whose\n\/\/    Before method was called,\n\/\/  - [Dispatcher Phase] after the [Commit Phase], the Dispatcher's appropriate\n\/\/    write method is called; the Dispatcher is responsible for determining whether\n\/\/    the response is indeed safe and writing it,\n\/\/  - if the handler attempts to write more than once, it is treated as an\n\/\/    unrecoverable error; the request processing ends abrubptly with a panic and\n\/\/    nothing else happens (note: this will change as soon as [After Phase] is\n\/\/    introduced)\n\/\/\n\/\/ Interceptors should NOT rely on the order they're run.\nfunc (m *ServeMux) ServeHTTP(w http.ResponseWriter, r *http.Request) {\n\tm.mux.ServeHTTP(w, r)\n}\n\n\/\/ ServeMuxConfig is a builder for ServeMux.\ntype ServeMuxConfig struct {\n\tdispatcher              Dispatcher\n\thandlers                []handlerRegistration\n\tinterceptors            []Interceptor\n\tmethodNotAllowedHandler handlerRegistration\n}\n\n\/\/ NewServeMuxConfig crates a ServeMuxConfig with the provided Dispatcher.

In future we plan to extend the searching\ncapabilities to include the other fields in the definition.\n\nNote:\n\n* metrictank is a multi-tenant system where different orgs cannot see each\n  other's data\n\n* any given metric may appear multiple times, under different organisations\n\n* Each metric path can be mapped to multiple metricDefinitions in the case that\n  fields other then the Name vary.  The most common occurrence of this is when\n  the Interval at which the metric is being collected has changed.\n\nInterface\n\n* Init()\n  This is the initialization step performed at startup. This method should\n  block until the index is ready to handle searches.\n\n* Stop():\n This will be called when metrictank is shutting down.\n\n* AddOrUpdate(*schema.MetricData, int32) Archive:\n  Every metric received will result in a call to this method to ensure the\n  metric has been added to the index. The method is passed the metricData\n  payload and the partition id of the metric\n\n* Get(string) (Archive, bool):\n  This method should return the MetricDefintion with the passed Id.\n\n* GetPath(string) (Archive, bool) []Archive:\n  This method should return the archives under the given path\n\n* List(int) []Archive:\n  This method should return all MetricDefinitions for the passed OrgId.  If the\n  passed OrgId is \"-1\", then all metricDefinitions across all organisations\n  should be returned.\n\n* Find(int, string, int64) ([]Node, error):\n  This method provides searches.  The method is passed an OrgId, a query\n  pattern and a unix timestamp. Searches should return all nodes that match for\n  the given OrgId and OrgId -1.  The pattern should be handled in the same way\n  Graphite would. see https:\/\/graphite.readthedocs.io\/en\/latest\/render_api.html#paths-and-wildcards\n  And the unix stimestamp is used to ignore series that have been stale since\n  the timestamp.\n\n* Delete(int, string) ([]Archive, error):\n  This method is used for deleting items from the index. The method is passed\n  an OrgId and a query pattern.  If the pattern matches a branch node, then\n  all leaf nodes on that branch should also be deleted.
