The host\n\tnegotiates file contracts with remote renters to earn money for storing\n\tother users' files.\n\tThe host requires the consensus set, transaction pool, and wallet.\n\tExample:\n\t\tsiad -M gctwh\nMiner (m):\n\tThe miner provides a basic CPU mining implementation as well as an API\n\tfor external miners to use.\n\tThe miner requires the consensus set, transaction pool, and wallet.\n\tExample:\n\t\tsiad -M gctwm\nExplorer (e):\n\tThe explorer provides statistics about the blockchain and can be\n\tqueried for information about specific transactions or other objects on\n\tthe blockchain.\n\tThe explorer requires the consenus set.\n\tExample:\n\t\tsiad -M gce`)\n}\n\n\/\/ main establishes a set of commands and flags using the cobra package.\nfunc main() {\n\tif build.DEBUG {\n\t\tfmt.Println(\"Running with debugging enabled\")\n\t}\n\troot := &cobra.Command{\n\t\tUse:   os.Args[0],\n\t\tShort: \"Sia Daemon v\" + build.Version,\n\t\tLong:  \"Sia Daemon v\" + build.Version,\n\t\tRun:   startDaemonCmd,\n\t}\n\n\troot.AddCommand(&cobra.Command{\n\t\tUse:   \"version\",\n\t\tShort: \"Print version information\",\n\t\tLong:  \"Print version information about the Sia Daemon\",\n\t\tRun:   versionCmd,\n\t})\n\n\troot.AddCommand(&cobra.Command{\n\t\tUse:   \"modules\",\n\t\tShort: \"List available modules for use with -M, --modules flag\",\n\t\tLong:  \"List available modules for use with -M, --modules flag and their uses\",\n\t\tRun:   modulesCmd,\n\t})\n\n\t\/\/ Set default values, which have the lowest priority.\n\troot.Flags().StringVarP(&globalConfig.Siad.RequiredUserAgent, \"agent\", \"\", \"Sia-Agent\", \"required substring for the user agent\")\n\troot.Flags().StringVarP(&globalConfig.Siad.HostAddr, \"host-addr\", \"\", \":9982\", \"which port the host listens on\")\n\troot.Flags().StringVarP(&globalConfig.Siad.ProfileDir, \"profile-directory\", \"\", \"profiles\", \"location of the profiling directory\")\n\troot.Flags().StringVarP(&globalConfig.Siad.APIaddr, \"api-addr\", \"\", \"localhost:9980\", \"which host:port the API server listens on\")\n\troot.Flags().StringVarP(&globalConfig.Siad.SiaDir, \"sia-directory\", \"d\", \"\", \"location of the sia directory\")\n\troot.Flags().BoolVarP(&globalConfig.Siad.NoBootstrap, \"no-bootstrap\", \"\", false, \"disable bootstrapping on this run\")\n\troot.Flags().BoolVarP(&globalConfig.Siad.Profile, \"profile\", \"\", false, \"enable profiling\")\n\troot.Flags().StringVarP(&globalConfig.Siad.RPCaddr, \"rpc-addr\", \"\", \":9981\", \"which port the gateway listens on\")\n\troot.Flags().StringVarP(&globalConfig.Siad.Modules, \"modules\", \"M\", \"cghrtw\", \"enabled modules, see 'siad modules' for more info\")\n\troot.Flags().BoolVarP(&globalConfig.Siad.AuthenticateAPI, \"authenticate-api\", \"\", false, \"enable API password protection\")\n\troot.Flags().BoolVarP(&globalConfig.Siad.AllowAPIBind, \"disable-api-security\", \"\", false, \"allow siad to listen on a non-localhost address (DANGEROUS)\")\n\n\t\/\/ Parse cmdline flags, overwriting both the default values and the config\n\t\/\/ file values.\n\tif err := root.Execute(); err != nil {\n\t\t\/\/ Since no commands return errors (all commands set Command.Run instead of\n\t\t\/\/ Command.RunE), Command.Execute() should only return an error on an\n\t\t\/\/ invalid command or flag.

The only required property that a user-\ndefined theme must have is a theme name.\n\nTheme file is a simple text file that has similar to INI file format:\n1. Every line started with '#' or '\/' is a comment line.\n2. Invalid lines - lines that do not contain symbol '=' - are skipped.\n3. Valid lines are splitted in two parts:\n    key - the text before the first '=' in the line\n    value - the text after the first '=' in the line (so, values can\n        include '=')\n    key and value are trimmed - spaces are removed from both ends.\n    If line starts and ends with quote or double quote symbol then\n    these symbols are removed, too. It is done to be able to start\n    or finish the object with a space rune\n4. There is no mandatory keys - all of them are optional\n5. Avaiable system keys that used to describe the theme:\n    'title' - the theme title\n    'author' - theme author\n    'version' - theme version\n    'parent' - name of the parent theme. If it is not set then the\n        'default' is used as a parent\n6. Non-system keys are divided into two groups: Colors and Objects\n    Colors are the keys that end with 'Back' or 'Text' - background\n        and text color, respectively. If theme manager cannot\n        value to color it panics. See Color*Back * Color*Text constants,\n        just drop 'Color' at the beginning of key name.\n        Rules of converting text to color:\n        1. If the value does not end neither with 'Back' nor with 'Text'\n            it is considered as raw attribute value(e.g, 'green bold')\n        2. If the value ends with 'Back' or 'Text' it means that one\n            of earlier defined attribute must be used. If the current\n            scheme does not have that attribute defined (e.g, it is\n            defined later in file) then parent theme attribute with\n            the same name is used. One can force using parent theme\n            colors - just add prefix 'parent.' to color name. This\n            may be useful if one wants some parent colors reversed.\n            Example:\n                ViewBack=ViewText\n                ViewText=ViewBack\n            this makes both colors the same because ViewBack is defined\n            before ViewText. Only ViewBack value is loaded from parent theme.\n            Better way is:\n                Viewback=parent.ViewText\n                ViewText=parent.ViewBack\n        Converting text to real color panics if a) the string does not look\n            like real color(e.g, typo as in 'grean bold'), b) parent theme\n            has not loaded yet, c) parent theme does not have the color\n            with the same name\n    Other keys are considered as objects - see Obj* constants, just drop\n        'Obj' at the beginning of the key name\n    One is not limited with only predefined color and object names.\n    The theme can inroduce its own objects, e.g. to provide a runes or\n        colors for new control that is not in standard library\nTo see the real world example of full featured theme, please see\n    included theme 'turbovision'\n*\/\ntype ThemeManager struct {\n\t\/\/ available theme list\n\tthemes map[string]theme\n\t\/\/ name of the current theme\n\tcurrent   string\n\tthemePath string\n\tversion   string\n}\n\nconst defaultTheme = \"default\"\nconst themeSuffix = \".theme\"\n\n\/\/ ThemeInfo is a detailed information about theme:\n\/\/ title, author, version number\ntype ThemeInfo struct {\n\tparent  string\n\ttitle   string\n\tauthor  string\n\tversion string\n}\n\n\/*\nA theme structure.

The only required property that a user-\ndefined theme must have is a theme name.\n\nTheme file is a simple text file that has similar to INI file format:\n1. Every line started with '#' or '\/' is a comment line.\n2. Invalid lines - lines that do not contain symbol '=' - are skipped.\n3. Valid lines are splitted in two parts:\n    key - the text before the first '=' in the line\n    value - the text after the first '=' in the line (so, values can\n        include '=')\n    key and value are trimmed - spaces are removed from both ends.\n    If line starts and ends with quote or double quote symbol then\n    these symbols are removed, too. It is done to be able to start\n    or finish the object with a space rune\n4. There is no mandatory keys - all of them are optional\n5. Avaiable system keys that used to describe the theme:\n    'title' - the theme title\n    'author' - theme author\n    'version' - theme version\n    'parent' - name of the parent theme. If it is not set then the\n        'default' is used as a parent\n6. Non-system keys are divided into two groups: Colors and Objects\n    Colors are the keys that end with 'Back' or 'Text' - background\n        and text color, respectively. If theme manager cannot\n        value to color it panics. See Color*Back * Color*Text constants,\n        just drop 'Color' at the beginning of key name.\n        Rules of converting text to color:\n        1. If the value does not end neither with 'Back' nor with 'Text'\n            it is considered as raw attribute value(e.g, 'green bold')\n        2. If the value ends with 'Back' or 'Text' it means that one\n            of earlier defined attribute must be used. If the current\n            scheme does not have that attribute defined (e.g, it is\n            defined later in file) then parent theme attribute with\n            the same name is used. One can force using parent theme\n            colors - just add prefix 'parent.' to color name. This\n            may be useful if one wants some parent colors reversed.\n            Example:\n                ViewBack=ViewText\n                ViewText=ViewBack\n            this makes both colors the same because ViewBack is defined\n            before ViewText. Only ViewBack value is loaded from parent theme.\n            Better way is:\n                Viewback=parent.ViewText\n                ViewText=parent.ViewBack\n        Converting text to real color panics if a) the string does not look\n            like real color(e.g, typo as in 'grean bold'), b) parent theme\n            has not loaded yet, c) parent theme does not have the color\n            with the same name\n    Other keys are considered as objects - see Obj* constants, just drop\n        'Obj' at the beginning of the key name\n    One is not limited with only predefined color and object names.\n    The theme can inroduce its own objects, e.g. to provide a runes or\n        colors for new control that is not in standard library\nTo see the real world example of full featured theme, please see\n    included theme 'turbovision'\n*\/\ntype ThemeManager struct {\n\t\/\/ available theme list\n\tthemes map[string]theme\n\t\/\/ name of the current theme\n\tcurrent   string\n\tthemePath string\n\tversion   string\n}\n\nconst defaultTheme = \"default\"\nconst themeSuffix = \".theme\"\n\n\/\/ ThemeInfo is a detailed information about theme:\n\/\/ title, author, version number\ntype ThemeInfo struct {\n\tparent  string\n\ttitle   string\n\tauthor  string\n\tversion string\n}\n\n\/*\nA theme structure.

That is, the build constraints:\n\/\/\n\/\/\t\/\/ +build linux darwin\n\/\/\t\/\/ +build 386\n\/\/\n\/\/ corresponds to the boolean formula:\n\/\/\n\/\/\t(linux OR darwin) AND 386\n\/\/\n\/\/ During a particular build, the following words are satisfied:\n\/\/\n\/\/\t- the target operating system, as spelled by runtime.GOOS\n\/\/\t- the target architecture, as spelled by runtime.GOARCH\n\/\/\t- the compiler being used, currently either \"gc\" or \"gccgo\"\n\/\/\t- \"cgo\", if ctxt.CgoEnabled is true\n\/\/\t- any additional words listed in ctxt.BuildTags\n\/\/\n\/\/ If a file's name, after stripping the extension and a possible _test suffix,\n\/\/ matches *_GOOS, *_GOARCH, or *_GOOS_GOARCH for any known operating\n\/\/ system and architecture values, then the file is considered to have an implicit\n\/\/ build constraint requiring those terms.\n\/\/\n\/\/ To keep a file from being considered for the build:\n\/\/\n\/\/\t\/\/ +build ignore\n\/\/\n\/\/ (any other unsatisfied word will work as well, but ``ignore'' is conventional.)\n\/\/\n\/\/ To build a file only when using cgo, and only on Linux and OS X:\n\/\/\n\/\/\t\/\/ +build linux,cgo darwin,cgo\n\/\/\n\/\/ Such a file is usually paired with another file implementing the\n\/\/ default functionality for other systems, which in this case would\n\/\/ carry the constraint:\n\/\/\n\/\/\t\/\/ +build !linux,!darwin !cgo\n\/\/\n\/\/ Naming a file dns_windows.go will cause it to be included only when\n\/\/ building the package for Windows; similarly, math_386.s will be included\n\/\/ only when building the package for 32-bit x86.\n\/\/\npackage build\n<|endoftext|>"}

The Stop method\nproduces similar behavior, closing the HTTP listener then permitting existing connections to wind down.\n\nTarantula provides a simple interface, tarantula.ResponderToHttp, that indicates a value that knows how to write \nitself to a http.ResponseWriter.

bound functions are expected to return values that\ncan be converted to JSON, and when they do, they will be provided to the browser.  Errors will override returned data\nand will be provded instead if they are present.\n\nTarantula is also somewhat clever about watching for SIGUSR1; it regards this as an indication that the service should\nenter a controlled shutdown, finishing any pending requests before permitting the Run method to return.  The Stop method\nproduces similar behavior, closing the HTTP listener then permitting existing connections to wind down.\n\nTarantula provides a simple interface, tarantula.ResponderToHttp, that indicates a value that knows how to write \nitself to a http.ResponseWriter.  A number of convenient wrappers can be found in Tarantula that implement this interface,\nincluding HttpError, ForwardToURL and WithTemplate.\n\nRefer to https:\/\/github.com\/swdunlop\/livefire-go for a more involved example for Tarantula.\n*\/\npackage tarantula\n\nimport (\n\t\"encoding\/json\"\n\t\"html\/template\"\n\t\"io\"\n\t\"net\"\n\t\"net\/http\"\n\t\"os\"\n\t\"os\/signal\"\n\t\"sync\"\n\t\"syscall\"\n)\n\n\/\/ NewService creates a new tarantula.Service that will (eventually) listen to the supplied TCP address.\nfunc NewService(addr string) *Service {\n\tsvc := new(Service)\n\tsvc.addr = addr\n\tsvc.mux = http.NewServeMux()\n\tsvc.server.Handler = svc\n\treturn svc\n}\n\n\/\/ Service collects trivia about a Tarantula HTTP service and maintains state.\ntype Service struct {\n\taddr     string\n\tpending  sync.WaitGroup\n\tmux      *http.ServeMux\n\tstarted  bool\n\tserver   http.Server\n\tlistener net.Listener\n}\n\n\/\/ ServeHTTP is an implementation of the http.ServeHTTP interface.\nfunc (svc *Service) ServeHTTP(rw http.ResponseWriter, req *http.Request) {\n\tsvc.pending.Add(1)\n\tdefer svc.pending.Done()\n\t\/\/TODO: recoverError here.\n\tsvc.mux.ServeHTTP(rw, req)\n}\n\nfunc (svc *Service) waitPending() {\n\tif svc.started {\n\t\tsvc.pending.Wait()\n\t}\n}\n\nfunc (svc *Service) handleSignals() {\n\tdefer svc.Stop()\n\tdone := make(chan os.Signal)\n\tsignal.Notify(done, syscall.SIGUSR1)\n\t<-done\n}\n\n\/\/ Initiates an eventual stop of the service by closing its listener.\nfunc (svc *Service) Stop() {\n\tsvc.listener.Close()\n}\n\n\/\/ Performs all configuration and preparation for the service, but does not\n\/\/ accept requests, see Run() for that.\nfunc (svc *Service) Start() error {\n\tvar err error\n\tif svc.started {\n\t\treturn nil\n\t}\n\tsvc.listener, err = net.Listen(\"tcp\", svc.addr)\n\tif err != nil {\n\t\treturn err\n\t}\n\tsvc.started = true\n\tgo svc.handleSignals()\n\treturn nil\n}\n\n\/\/ Serves requests in a loop until the service is Stopped.

See the packages under admin for clients that operate on databases\nand instances.\n\nSee https:\/\/cloud.google.com\/spanner\/docs\/getting-started\/go\/ for an\nintroduction to Cloud Spanner and additional help on using this API.\n\nSee https:\/\/godoc.org\/cloud.google.com\/go for authentication, timeouts,\nconnection pooling and similar aspects of this package.\n\n\nCreating a Client\n\nTo start working with this package, create a client that refers to the database\nof interest:\n\n    ctx := context.Background()\n    client, err := spanner.NewClient(ctx, \"projects\/P\/instances\/I\/databases\/D\")\n    if err != nil {\n        \/\/ TODO: Handle error.\n    }\n    defer client.Close()\n\nRemember to close the client after use to free up the sessions in the session\npool.\n\n\nSimple Reads and Writes\n\nTwo Client methods, Apply and Single, work well for simple reads and writes. As\na quick introduction, here we write a new row to the database and read it back:\n\n    _, err := client.Apply(ctx, []*spanner.Mutation{\n        spanner.Insert(\"Users\",\n            []string{\"name\", \"email\"},\n            []interface{}{\"alice\", \"a@example.com\"})})\n    if err != nil {\n        \/\/ TODO: Handle error.\n    }\n    row, err := client.Single().ReadRow(ctx, \"Users\",\n        spanner.Key{\"alice\"}, []string{\"email\"})\n    if err != nil {\n        \/\/ TODO: Handle error.\n    }\n\nAll the methods used above are discussed in more detail below.\n\n\nKeys\n\nEvery Cloud Spanner row has a unique key, composed of one or more columns.\nConstruct keys with a literal of type Key:\n\n   key1 := spanner.Key{\"alice\"}\n\n\nKeyRanges\n\nThe keys of a Cloud Spanner table are ordered. You can specify ranges of keys\nusing the KeyRange type:\n\n    kr1 := spanner.KeyRange{Start: key1, End: key2}\n\nBy default, a KeyRange includes its start key but not its end key. Use\nthe Kind field to specify other boundary conditions:\n\n    \/\/ include both keys\n    kr2 := spanner.KeyRange{Start: key1, End: key2, Kind: spanner.ClosedClosed}\n\n\nKeySets\n\nA KeySet represents a set of keys. A single Key or KeyRange can act as a KeySet.\nUse the KeySets function to build the union of several KeySets:\n\n    ks1 := spanner.KeySets(key1, key2, kr1, kr2)\n\nAllKeys returns a KeySet that refers to all the keys in a table:\n\n    ks2 := spanner.AllKeys()\n\n\nTransactions\n\nAll Cloud Spanner reads and writes occur inside transactions. There are two\ntypes of transactions, read-only and read-write. Read-only transactions cannot\nchange the database, do not acquire locks, and may access either the current\ndatabase state or states in the past. Read-write transactions can read the\ndatabase before writing to it, and always apply to the most recent database\nstate.\n\n\nSingle Reads\n\nThe simplest and fastest transaction is a ReadOnlyTransaction that supports a\nsingle read operation. Use Client.Single to create such a transaction. You can\nchain the call to Single with a call to a Read method.\n\nWhen you only want one row whose key you know, use ReadRow. Provide the table\nname, key, and the columns you want to read:\n\n    row, err := client.Single().ReadRow(ctx, \"Accounts\", spanner.Key{\"alice\"}, []string{\"balance\"})\n\nRead multiple rows with the Read method. It takes a table name, KeySet, and list\nof columns:\n\n    iter := client.Single().Read(ctx, \"Accounts\", keyset1, columns)\n\nRead returns a RowIterator. You can call the Do method on the iterator and pass\na callback:\n\n    err := iter.Do(func(row *Row) error {\n       \/\/ TODO: use row\n       return nil\n    })\n\nRowIterator also follows the standard pattern for the Google\nCloud Client Libraries:\n\n    defer iter.Stop()\n    for {\n        row, err := iter.Next()\n        if err == iterator.Done {\n            break\n        }\n        if err != nil {\n            \/\/ TODO: Handle error.\n        }\n        \/\/ TODO: use row\n    }\n\nAlways call Stop when you finish using an iterator this way, whether or not you\niterate to the end. (Failing to call Stop could lead you to exhaust the\ndatabase's session quota.)\n\nTo read rows with an index, use ReadUsingIndex.\n\nStatements\n\nThe most general form of reading uses SQL statements. Construct a Statement\nwith NewStatement, setting any parameters using the Statement's Params map:\n\n    stmt := spanner.NewStatement(\"SELECT First, Last FROM SINGERS WHERE Last >= @start\")\n    stmt.Params[\"start\"] = \"Dylan\"\n\nYou can also construct a Statement directly with a struct literal, providing\nyour own map of parameters.\n\nUse the Query method to run the statement and obtain an iterator:\n\n    iter := client.Single().Query(ctx, stmt)\n\n\nRows\n\nOnce you have a Row, via an iterator or a call to ReadRow, you can extract\ncolumn values in several ways. Pass in a pointer to a Go variable of the\nappropriate type when you extract a value.\n\nYou can extract by column position or name:\n\n   err := row.Column(0, &name)\n   err = row.ColumnByName(\"balance\", &balance)\n\nYou can extract all the columns at once:\n\n   err = row.Columns(&name, &balance)\n\nOr you can define a Go struct that corresponds to your columns, and extract\ninto that:\n\n   var s struct { Name string; Balance int64 }\n   err = row.ToStruct(&s)\n\n\nFor Cloud Spanner columns that may contain NULL, use one of the NullXXX types,\nlike NullString:\n\n    var ns spanner.NullString\n    if err := row.Column(0, &ns); err != nil {\n        \/\/ TODO: Handle error.\n    }\n    if ns.Valid {\n        fmt.Println(ns.StringVal)\n    } else {\n        fmt.Println(\"column is NULL\")\n    }\n\n\nMultiple Reads\n\nTo perform more than one read in a transaction, use ReadOnlyTransaction:\n\n    txn := client.ReadOnlyTransaction()\n    defer txn.Close()\n    iter := txn.Query(ctx, stmt1)\n    \/\/ ...\n    iter =  txn.Query(ctx, stmt2)\n    \/\/ ...\n\nYou must call Close when you are done with the transaction.\n\n\nTimestamps and Timestamp Bounds\n\nCloud Spanner read-only transactions conceptually perform all their reads at a\nsingle moment in time, called the transaction's read timestamp. Once a read has\nstarted, you can call ReadOnlyTransaction's Timestamp method to obtain the read\ntimestamp.\n\nBy default, a transaction will pick the most recent time (a time where all\npreviously committed transactions are visible) for its reads. This provides the\nfreshest data, but may involve some delay. You can often get a quicker response\nif you are willing to tolerate \"stale\" data. You can control the read timestamp\nselected by a transaction by calling the WithTimestampBound method on the\ntransaction before using it. For example, to perform a query on data that is at\nmost one minute stale, use\n\n    client.Single().\n        WithTimestampBound(spanner.MaxStaleness(1*time.Minute)).\n        Query(ctx, stmt)\n\nSee the documentation of TimestampBound for more details.\n\n\nMutations\n\nTo write values to a Cloud Spanner database, construct a Mutation. The spanner\npackage has functions for inserting, updating and deleting rows. Except for the\nDelete methods, which take a Key or KeyRange, each mutation-building function\ncomes in three varieties.\n\nOne takes lists of columns and values along with the table name:\n\n    m1 := spanner.Insert(\"Users\",\n        []string{\"name\", \"email\"},\n        []interface{}{\"alice\", \"a@example.com\"})\n\nOne takes a map from column names to values:\n\n    m2 := spanner.InsertMap(\"Users\", map[string]interface{}{\n        \"name\":  \"alice\",\n        \"email\": \"a@example.com\",\n    })\n\nAnd the third accepts a struct value, and determines the columns from the\nstruct field names:\n\n    type User struct { Name, Email string }\n    u := User{Name: \"alice\", Email: \"a@example.com\"}\n    m3, err := spanner.InsertStruct(\"Users\", u)\n\n\nWrites\n\nTo apply a list of mutations to the database, use Apply:\n\n    _, err := client.Apply(ctx, []*spanner.Mutation{m1, m2, m3})\n\nIf you need to read before writing in a single transaction, use a\nReadWriteTransaction. ReadWriteTransactions may be aborted automatically by the\nbackend and need to be retried. You pass in a function to ReadWriteTransaction,\nand the client will handle the retries automatically. Use the transaction's\nBufferWrite method to buffer mutations, which will all be executed at the end\nof the transaction:\n\n    _, err := client.ReadWriteTransaction(ctx, func(ctx context.Context, txn *spanner.ReadWriteTransaction) error {\n        var balance int64\n        row, err := txn.ReadRow(ctx, \"Accounts\", spanner.Key{\"alice\"}, []string{\"balance\"})\n        if err != nil {\n            \/\/ The transaction function will be called again if the error code\n            \/\/ of this error is Aborted. The backend may automatically abort\n            \/\/ any read\/write transaction if it detects a deadlock or other\n            \/\/ problems.\n            return err\n        }\n        if err := row.Column(0, &balance); err != nil {\n            return err\n        }\n\n        if balance <= 10 {\n            return errors.New(\"insufficient funds in account\")\n        }\n        balance -= 10\n        m := spanner.Update(\"Accounts\", []string{\"user\", \"balance\"}, []interface{}{\"alice\", balance})\n        \/\/ The buffered mutation will be committed.  If the commit\n        \/\/ fails with an Aborted error, this function will be called\n        \/\/ again.\n        return txn.BufferWrite([]*spanner.Mutation{m})\n    })\n\n\nStructs\n\nCloud Spanner STRUCT (aka STRUCT) values\n(https:\/\/cloud.google.com\/spanner\/docs\/data-types#struct-type) can be\nrepresented by a Go struct value.\n\nA proto StructType is built from the field types and field tag information of\nthe Go struct. If a field in the struct type definition has a\n\"spanner:<field_name>\" tag, then the value of the \"spanner\" key in the tag is\nused as the name for that field in the built StructType, otherwise the field\nname in the struct definition is used. To specify a field with an empty field\nname in a Cloud Spanner STRUCT type, use the `spanner:\"\"` tag annotation against\nthe corresponding field in the Go struct's type definition.\n\nA STRUCT value can contain STRUCT-typed and Array-of-STRUCT typed fields and\nthese can be specified using named struct-typed and []struct-typed fields inside\na Go struct. However, embedded struct fields are not allowed. Unexported struct\nfields are ignored.\n\nNULL STRUCT values in Cloud Spanner are typed. A nil pointer to a Go struct\nvalue can be used to specify a NULL STRUCT value of the corresponding\nStructType.  Nil and empty slices of a Go STRUCT type can be used to specify\nNULL and empty array values respectively of the corresponding StructType. A\nslice of pointers to a Go struct type can be used to specify an array of\nNULL-able STRUCT values.\n\n\nDML and Partitioned DML\n\nSpanner supports DML statements like INSERT, UPDATE and DELETE. Use\nReadWriteTransaction.Update to run DML statements. It returns the number of rows\naffected. (You can call use ReadWriteTransaction.Query with a DML statement. The\nfirst call to Next on the resulting RowIterator will return iterator.Done, and\nthe RowCount field of the iterator will hold the number of affected rows.)\n\nFor large databases, it may be more efficient to partition the DML statement.\nUse client.PartitionedUpdate to run a DML statement in this way. Not all DML\nstatements can be partitioned.\n\n\nTracing\n\nThis client has been instrumented to use OpenCensus tracing\n(http:\/\/opencensus.io). To enable tracing, see \"Enabling Tracing for a Program\"\nat https:\/\/godoc.org\/go.opencensus.io\/trace. OpenCensus tracing requires Go 1.8\nor higher.\n*\/\npackage spanner \/\/ import \"cloud.google.com\/go\/spanner\"\n\n\/\/ clientUserAgent identifies the version of this package.\n\/\/ It should be the same as https:\/\/pkg.go.dev\/cloud.google.com\/go\/spanner.\n\/\/ TODO: We will want to automate the version with a bash script.\nconst clientUserAgent = \"spanner-go\/v1.12.0\"\n<commit_msg>docs(spanner): add example for using SPANNER_EMULATOR_HOST (#4723)<commit_after>\/*\nCopyright 2017 Google LLC\n\nLicensed under the Apache License, Version 2.0 (the \"License\");\nyou may not use this file except in compliance with the License.\nYou may obtain a copy of the License at\n\n    http:\/\/www.apache.org\/licenses\/LICENSE-2.0\n\nUnless required by applicable law or agreed to in writing, software\ndistributed under the License is distributed on an \"AS IS\" BASIS,\nWITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied.\nSee the License for the specific language governing permissions and\nlimitations under the License.\n*\/\n\n\/*\nPackage spanner provides a client for reading and writing to Cloud Spanner\ndatabases.

You can call the Do method on the iterator and pass\na callback:\n\n    err := iter.Do(func(row *Row) error {\n       \/\/ TODO: use row\n       return nil\n    })\n\nRowIterator also follows the standard pattern for the Google\nCloud Client Libraries:\n\n    defer iter.Stop()\n    for {\n        row, err := iter.Next()\n        if err == iterator.Done {\n            break\n        }\n        if err != nil {\n            \/\/ TODO: Handle error.\n        }\n        \/\/ TODO: use row\n    }\n\nAlways call Stop when you finish using an iterator this way, whether or not you\niterate to the end. (Failing to call Stop could lead you to exhaust the\ndatabase's session quota.)\n\nTo read rows with an index, use ReadUsingIndex.\n\nStatements\n\nThe most general form of reading uses SQL statements. Construct a Statement\nwith NewStatement, setting any parameters using the Statement's Params map:\n\n    stmt := spanner.NewStatement(\"SELECT First, Last FROM SINGERS WHERE Last >= @start\")\n    stmt.Params[\"start\"] = \"Dylan\"\n\nYou can also construct a Statement directly with a struct literal, providing\nyour own map of parameters.\n\nUse the Query method to run the statement and obtain an iterator:\n\n    iter := client.Single().Query(ctx, stmt)\n\n\nRows\n\nOnce you have a Row, via an iterator or a call to ReadRow, you can extract\ncolumn values in several ways. Pass in a pointer to a Go variable of the\nappropriate type when you extract a value.\n\nYou can extract by column position or name:\n\n   err := row.Column(0, &name)\n   err = row.ColumnByName(\"balance\", &balance)\n\nYou can extract all the columns at once:\n\n   err = row.Columns(&name, &balance)\n\nOr you can define a Go struct that corresponds to your columns, and extract\ninto that:\n\n   var s struct { Name string; Balance int64 }\n   err = row.ToStruct(&s)\n\n\nFor Cloud Spanner columns that may contain NULL, use one of the NullXXX types,\nlike NullString:\n\n    var ns spanner.NullString\n    if err := row.Column(0, &ns); err != nil {\n        \/\/ TODO: Handle error.\n    }\n    if ns.Valid {\n        fmt.Println(ns.StringVal)\n    } else {\n        fmt.Println(\"column is NULL\")\n    }\n\n\nMultiple Reads\n\nTo perform more than one read in a transaction, use ReadOnlyTransaction:\n\n    txn := client.ReadOnlyTransaction()\n    defer txn.Close()\n    iter := txn.Query(ctx, stmt1)\n    \/\/ ...\n    iter =  txn.Query(ctx, stmt2)\n    \/\/ ...\n\nYou must call Close when you are done with the transaction.\n\n\nTimestamps and Timestamp Bounds\n\nCloud Spanner read-only transactions conceptually perform all their reads at a\nsingle moment in time, called the transaction's read timestamp. Once a read has\nstarted, you can call ReadOnlyTransaction's Timestamp method to obtain the read\ntimestamp.\n\nBy default, a transaction will pick the most recent time (a time where all\npreviously committed transactions are visible) for its reads. This provides the\nfreshest data, but may involve some delay. You can often get a quicker response\nif you are willing to tolerate \"stale\" data. You can control the read timestamp\nselected by a transaction by calling the WithTimestampBound method on the\ntransaction before using it. For example, to perform a query on data that is at\nmost one minute stale, use\n\n    client.Single().\n        WithTimestampBound(spanner.MaxStaleness(1*time.Minute)).\n        Query(ctx, stmt)\n\nSee the documentation of TimestampBound for more details.\n\n\nMutations\n\nTo write values to a Cloud Spanner database, construct a Mutation. The spanner\npackage has functions for inserting, updating and deleting rows. Except for the\nDelete methods, which take a Key or KeyRange, each mutation-building function\ncomes in three varieties.\n\nOne takes lists of columns and values along with the table name:\n\n    m1 := spanner.Insert(\"Users\",\n        []string{\"name\", \"email\"},\n        []interface{}{\"alice\", \"a@example.com\"})\n\nOne takes a map from column names to values:\n\n    m2 := spanner.InsertMap(\"Users\", map[string]interface{}{\n        \"name\":  \"alice\",\n        \"email\": \"a@example.com\",\n    })\n\nAnd the third accepts a struct value, and determines the columns from the\nstruct field names:\n\n    type User struct { Name, Email string }\n    u := User{Name: \"alice\", Email: \"a@example.com\"}\n    m3, err := spanner.InsertStruct(\"Users\", u)\n\n\nWrites\n\nTo apply a list of mutations to the database, use Apply:\n\n    _, err := client.Apply(ctx, []*spanner.Mutation{m1, m2, m3})\n\nIf you need to read before writing in a single transaction, use a\nReadWriteTransaction. ReadWriteTransactions may be aborted automatically by the\nbackend and need to be retried. You pass in a function to ReadWriteTransaction,\nand the client will handle the retries automatically. Use the transaction's\nBufferWrite method to buffer mutations, which will all be executed at the end\nof the transaction:\n\n    _, err := client.ReadWriteTransaction(ctx, func(ctx context.Context, txn *spanner.ReadWriteTransaction) error {\n        var balance int64\n        row, err := txn.ReadRow(ctx, \"Accounts\", spanner.Key{\"alice\"}, []string{\"balance\"})\n        if err != nil {\n            \/\/ The transaction function will be called again if the error code\n            \/\/ of this error is Aborted. The backend may automatically abort\n            \/\/ any read\/write transaction if it detects a deadlock or other\n            \/\/ problems.\n            return err\n        }\n        if err := row.Column(0, &balance); err != nil {\n            return err\n        }\n\n        if balance <= 10 {\n            return errors.New(\"insufficient funds in account\")\n        }\n        balance -= 10\n        m := spanner.Update(\"Accounts\", []string{\"user\", \"balance\"}, []interface{}{\"alice\", balance})\n        \/\/ The buffered mutation will be committed.  If the commit\n        \/\/ fails with an Aborted error, this function will be called\n        \/\/ again.\n        return txn.BufferWrite([]*spanner.Mutation{m})\n    })\n\n\nStructs\n\nCloud Spanner STRUCT (aka STRUCT) values\n(https:\/\/cloud.google.com\/spanner\/docs\/data-types#struct-type) can be\nrepresented by a Go struct value.\n\nA proto StructType is built from the field types and field tag information of\nthe Go struct. If a field in the struct type definition has a\n\"spanner:<field_name>\" tag, then the value of the \"spanner\" key in the tag is\nused as the name for that field in the built StructType, otherwise the field\nname in the struct definition is used. To specify a field with an empty field\nname in a Cloud Spanner STRUCT type, use the `spanner:\"\"` tag annotation against\nthe corresponding field in the Go struct's type definition.\n\nA STRUCT value can contain STRUCT-typed and Array-of-STRUCT typed fields and\nthese can be specified using named struct-typed and []struct-typed fields inside\na Go struct. However, embedded struct fields are not allowed. Unexported struct\nfields are ignored.\n\nNULL STRUCT values in Cloud Spanner are typed. A nil pointer to a Go struct\nvalue can be used to specify a NULL STRUCT value of the corresponding\nStructType.  Nil and empty slices of a Go STRUCT type can be used to specify\nNULL and empty array values respectively of the corresponding StructType. A\nslice of pointers to a Go struct type can be used to specify an array of\nNULL-able STRUCT values.\n\n\nDML and Partitioned DML\n\nSpanner supports DML statements like INSERT, UPDATE and DELETE. Use\nReadWriteTransaction.Update to run DML statements. It returns the number of rows\naffected. (You can call use ReadWriteTransaction.Query with a DML statement. The\nfirst call to Next on the resulting RowIterator will return iterator.Done, and\nthe RowCount field of the iterator will hold the number of affected rows.)\n\nFor large databases, it may be more efficient to partition the DML statement.\nUse client.PartitionedUpdate to run a DML statement in this way. Not all DML\nstatements can be partitioned.\n\n\nTracing\n\nThis client has been instrumented to use OpenCensus tracing\n(http:\/\/opencensus.io). To enable tracing, see \"Enabling Tracing for a Program\"\nat https:\/\/godoc.org\/go.opencensus.io\/trace. OpenCensus tracing requires Go 1.8\nor higher.\n*\/\npackage spanner \/\/ import \"cloud.google.com\/go\/spanner\"\n\n\/\/ clientUserAgent identifies the version of this package.\n\/\/ It should be the same as https:\/\/pkg.go.dev\/cloud.google.com\/go\/spanner.\n\/\/ TODO: We will want to automate the version with a bash script.\nconst clientUserAgent = \"spanner-go\/v1.12.0\"\n<|endoftext|>"}

We need to use Unwrap\n\t\/\/   in these cases to traverse those errors and dig down to the next\n\t\/\/   merry error.\n\t\/\/ - Some error packages, including our own, do funky stuff with Unwrap(),\n\t\/\/   returning shims types to control the unwrapping order, rather than\n\t\/\/   the actual, raw wrapped error.  Typically, these shims implement\n\t\/\/   Is\/As to delegate to the raw error they encapsulate, but implement\n\t\/\/   Unwrap by encapsulating the raw error in another shim.  So if we're looking\n\t\/\/   for a raw error type, we can't just use Unwrap() and do type assertions\n\t\/\/   against the result.  We have to use errors.As(), to allow the shims to delegate\n\t\/\/   the type assertion to the raw error correctly.\n\t\/\/\n\t\/\/ Based on all these constraints, we use errors.As() with an internal interface\n\t\/\/ that can only be implemented by our internal error types.  When one is found,\n\t\/\/ we handle each of our internal types as a special case.

It's tricky:\n\t\/\/\n\t\/\/ - Lookup should only search the current error, but not causes.  errWithCause's\n\t\/\/   Unwrap() will eventually unwrap to the cause, so we don't want to just\n\t\/\/   search the entire stream of errors returned by Unwrap.\n\t\/\/ - We need to handle cases where error implementations created outside\n\t\/\/   this package are in the middle of the chain.  We need to use Unwrap\n\t\/\/   in these cases to traverse those errors and dig down to the next\n\t\/\/   merry error.\n\t\/\/ - Some error packages, including our own, do funky stuff with Unwrap(),\n\t\/\/   returning shims types to control the unwrapping order, rather than\n\t\/\/   the actual, raw wrapped error.  Typically, these shims implement\n\t\/\/   Is\/As to delegate to the raw error they encapsulate, but implement\n\t\/\/   Unwrap by encapsulating the raw error in another shim.  So if we're looking\n\t\/\/   for a raw error type, we can't just use Unwrap() and do type assertions\n\t\/\/   against the result.  We have to use errors.As(), to allow the shims to delegate\n\t\/\/   the type assertion to the raw error correctly.\n\t\/\/\n\t\/\/ Based on all these constraints, we use errors.As() with an internal interface\n\t\/\/ that can only be implemented by our internal error types.  When one is found,\n\t\/\/ we handle each of our internal types as a special case.  For errWithCause, we\n\t\/\/ traverse to the wrapped error, ignoring the cause and the funky Unwrap logic.\n\t\/\/ We could have just used errors.As(err, *errWithValue), but that would have\n\t\/\/ traversed into the causes.\n\n\tfor {\n\t\tswitch t := err.(type) {\n\t\tcase *errWithValue:\n\t\t\tif t.key == key {\n\t\t\t\treturn t.value, true\n\t\t\t}\n\t\t\terr = t.err\n\t\tcase *errWithCause:\n\t\t\terr = t.err\n\t\tdefault:\n\t\t\tif internal.As(err, &merr) {\n\t\t\t\terr = merr\n\t\t\t} else {\n\t\t\t\treturn nil, false\n\t\t\t}\n\t\t}\n\t}\n}\n\n\/\/ Values returns a map of all values attached to the error\n\/\/ If a key has been attached multiple times, the map will\n\/\/ contain the last value mapped\n\/\/ If e is nil, returns nil.\nfunc Values(err error) map[interface{}]interface{} {\n\tvar values map[interface{}]interface{}\n\n\tvar merr interface {\n\t\terror\n\t\tisMerryError()\n\t}\n\n\tfor {\n\t\tswitch t := err.(type) {\n\t\tcase *errWithValue:\n\t\t\tif _, ok := values[t.key]; !ok {\n\t\t\t\tif values == nil {\n\t\t\t\t\tvalues = map[interface{}]interface{}{}\n\t\t\t\t}\n\t\t\t\tvalues[t.key] = t.value\n\t\t\t}\n\t\t\terr = t.err\n\t\tcase *errWithCause:\n\t\t\terr = t.err\n\t\tdefault:\n\t\t\tif internal.As(err, &merr) {\n\t\t\t\terr = merr\n\t\t\t} else {\n\t\t\t\treturn values\n\t\t\t}\n\t\t}\n\t}\n\n\tfor err != nil {\n\t\tif e, ok := err.(*errWithValue); ok {\n\t\t\tif _, ok := values[e.key]; !ok {\n\t\t\t\tif values == nil {\n\t\t\t\t\tvalues = map[interface{}]interface{}{}\n\t\t\t\t}\n\t\t\t\tvalues[e.key] = e.value\n\t\t\t}\n\t\t}\n\t\terr = internal.Unwrap(err)\n\t}\n\n\treturn values\n}\n\n\/\/ Stack returns the stack attached to an error, or nil if one is not attached\n\/\/ If e is nil, returns nil.\nfunc Stack(err error) []uintptr {\n\tstack, _ := Value(err, errKeyStack).([]uintptr)\n\treturn stack\n}\n\n\/\/ HTTPCode converts an error to an http status code.

It is a thin wrapper over the\n\/\/ standard net\/http client library and exposes nearly the same public API.\n\/\/ This makes retryablehttp very easy to drop into existing programs.\n\/\/\n\/\/ retryablehttp performs automatic retries under certain conditions. Mainly, if\n\/\/ an error is returned by the client (connection errors etc), or if a 500-range\n\/\/ response is received, then a retry is invoked. Otherwise, the response is\n\/\/ returned and left to the caller to interpret.\n\/\/\n\/\/ The main difference from net\/http is that requests which take a request body\n\/\/ (POST\/PUT et. al) require an io.ReadSeeker to be provided. This enables the\n\/\/ request body to be \"rewound\" if the initial request fails so that the full\n\/\/ request can be attempted again.\npackage retryablehttp\n\nimport (\n\t\"fmt\"\n\t\"io\"\n\t\"io\/ioutil\"\n\t\"log\"\n\t\"math\"\n\t\"net\/http\"\n\t\"net\/url\"\n\t\"os\"\n\t\"strings\"\n\t\"time\"\n\n\t\"github.com\/hashicorp\/go-cleanhttp\"\n)\n\nvar (\n\t\/\/ Default retry configuration\n\tdefaultRetryWaitMin = 1 * time.Second\n\tdefaultRetryWaitMax = 5 * time.Minute\n\tdefaultRetryMax     = 32\n\n\t\/\/ defaultClient is used for performing requests without explicitly making\n\t\/\/ a new client.

Note\n\/\/ that as soon as one peer contacts another via waddell, the 2nd peer will have\n\/\/ the 1st peer's address and be able to reply using it.\n\/\/\n\/\/ Peers can obtain new ids simply by reconnecting to waddell, and depending on\n\/\/ security requirements it may be a good idea to do so periodically.\n\/\/\n\/\/\n\/\/ Here is an example exchange between two peers:\n\/\/\n\/\/   peer 1 -> waddell server : connect\n\/\/\n\/\/   waddell server -> peer 1 : send newly assigned peer id\n\/\/\n\/\/   peer 2 -> waddell server : connect\n\/\/\n\/\/   waddell server -> peer 2 : send newly assigned peer id\n\/\/\n\/\/   (out of band)            : peer 1 lets peer 2 know about its id\n\/\/\n\/\/   peer 2 -> waddell server : send message to peer 1\n\/\/\n\/\/   waddell server -> peer 1 : deliver message from peer 2 (includes peer 2's id)\n\/\/\n\/\/   peer 1 -> waddell server : send message to peer 2\n\/\/\n\/\/   etc ..\n\/\/\n\/\/\n\/\/ Message structure on the wire (bits):\n\/\/\n\/\/   0-15    Frame Length    - waddell uses github.com\/getlantern\/framed to\n\/\/                             frame messages. framed uses the first 16 bits of\n\/\/                             the message to indicate the length of the frame\n\/\/                             (Little Endian).\n\/\/\n\/\/   16-79   Address Part 1  - 64-bit integer in Little Endian byte order for\n\/\/                             first half of peer id identifying recipient (on\n\/\/                             messages to waddell) or sender (on messages from\n\/\/                             waddell).\n\/\/\n\/\/   80-143  Address Part 2  - 64-bit integer in Little Endian byte order for\n\/\/                             second half of peer id\n\/\/\n\/\/   144+    Message Body    - whatever data the client sent\n\/\/\npackage waddell\n\nimport (\n\t\"github.com\/getlantern\/buuid\"\n\t\"github.com\/getlantern\/golog\"\n)\n\nconst (\n\tPEER_ID_LENGTH   = buuid.EncodedLength\n\tWADDELL_OVERHEAD = 18 \/\/ bytes of overhead imposed by waddell\n)\n\nvar (\n\tlog = golog.LoggerFor(\"waddell.client\")\n\n\tkeepAlive = []byte{'k'}\n)\n\n\/\/ PeerId is an identifier for a waddell peer\ntype PeerId buuid.ID\n\n\/\/ PeerIdFromString constructs a PeerId from the string-encoded version of a\n\/\/ uuid.UUID.\nfunc PeerIdFromString(s string) (PeerId, error) {\n\tid, err := buuid.FromString(s)\n\treturn PeerId(id), err\n}\n\nfunc (id PeerId) String() string {\n\treturn buuid.ID(id).String()\n}\n\nfunc readPeerId(b []byte) (PeerId, error) {\n\tid, err := buuid.Read(b)\n\treturn PeerId(id), err\n}\n\nfunc randomPeerId() PeerId {\n\treturn PeerId(buuid.Random())\n}\n\nfunc (id PeerId) write(b []byte) error {\n\treturn buuid.ID(id).Write(b)\n}\n\nfunc (id PeerId) toBytes() []byte {\n\treturn buuid.ID(id).ToBytes()\n}\n<|endoftext|>"}

The focus of this package is not to provide the most fully featured\n\/\/ MsgPack implementation out there, but rather support the main data types that I\n\/\/ use in my work (most of the basic types, also []interface{} and map[string]interface{}).\n\/\/ You'll notice that I don't use the `reflect` package at all, and that's because I\n\/\/ wanted to see what code looked like when you just did a switch on types instead of\n\/\/ using runtime reflection to figure out the types. This of course comes at the cost\n\/\/ of not being able to extend this MsgPack implementation to arbitrary data types.\n\/\/ Implementing a new type on your own is not difficult, though.\n\/\/\n\/\/ Coming up next are some more convenience methods for doing decoding and encoding\n\/\/ through writer\/reader\/buffer interfaces\npackage msgpack\n\nimport (\n\t\"sync\"\n)\n\nconst DEFAULT_ARR_SIZE = 15\n\nvar arrpool = sync.Pool{\n\tNew: func() interface{} {\n\t\treturn make([]interface{}, DEFAULT_ARR_SIZE)\n\t},\n}\n\nfunc getNewArray(length int) []interface{} {\n\tif length <= 15 {\n\t\treturn arrpool.Get().([]interface{})[:length]\n\t} else {\n\t\treturn make([]interface{}, length)\n\t}\n}\n\n\/** Each of these functions should take 3 arguments: the buffer to add into, an\n * offset into that buffer (where our writes start), and the value to encode.\n * After encoding the value and placing the byte sequence in the buffer\n * starting at the given offset, the function should return the next available\n * place to place bytes (the next offset to use)\n *\/\n\nfunc encodeNil(buf []byte, offset int) int {\n\tbuf[offset] = byte(0xc0)\n\treturn offset + 1\n}\n\nfunc encodeBool(buf []byte, offset int, val bool) int {\n\tif val {\n\t\tbuf[offset] = byte(0xc3)\n\t} else {\n\t\tbuf[offset] = byte(0xc2)\n\t}\n\treturn offset + 1\n}\n\nfunc encodeInt(buf []byte, offset, val int) int {\n\tif val < 128 && val >= 0 {\n\t\tbuf[offset] = byte(0x7f & val)\n\t\toffset += 1\n\t} else if val < 0 && val > -32 {\n\t\tbuf[offset] = byte(0xe0 | (0x1f & -val))\n\t\toffset += 1\n\t} else { \/\/ go to int64\n\t\t\/\/ find the smallest mask we can use\n\t\tswitch val {\n\t\tcase val & 0xff: \/\/ maybe 8 bit\n\t\t\toffset = encodeInt8(buf, offset, int64(val))\n\t\tcase val & 0xffff: \/\/ maybe 16 bit\n\t\t\toffset = encodeInt16(buf, offset, int64(val))\n\t\tcase val & 0xffffffff: \/\/ maybe 32 bit\n\t\t\toffset = encodeInt32(buf, offset, int64(val))\n\t\tdefault:\n\t\t\toffset = encodeInt64(buf, offset, int64(val))\n\t\t}\n\t}\n\treturn offset\n}\n\nfunc encodeInt8(buf []byte, offset int, val int64) int {\n\tif val > 0x7f {\n\t\treturn encodeInt16(buf, offset, val)\n\t}\n\tbuf[offset] = byte(0xd0)\n\tbuf[offset+1] = byte(val)\n\treturn offset + 2\n}\n\nfunc encodeInt16(buf []byte, offset int, val int64) int {\n\tif val > 0x7fff {\n\t\treturn encodeInt32(buf, offset, val)\n\t}\n\tbuf[offset] = byte(0xd1)\n\tbuf[offset+1] = byte(val >> 8)\n\tbuf[offset+2] = byte(val & 0xff)\n\treturn offset + 3\n}\n\nfunc encodeInt32(buf []byte, offset int, val int64) int {\n\tif val > 0x7fffffff {\n\t\treturn encodeInt64(buf, offset, val)\n\t}\n\tbuf[offset] = byte(0xd2)\n\tbuf[offset+1] = byte(val >> 24)\n\tbuf[offset+2] = byte(val >> 16)\n\tbuf[offset+3] = byte(val >> 8)\n\tbuf[offset+4] = byte(val & 0xff)\n\treturn offset + 5\n}\n\nfunc encodeInt64(buf []byte, offset int, val int64) int {\n\tbuf[offset] = byte(0xd3)\n\tbuf[offset+1] = byte(val >> 56)\n\tbuf[offset+2] = byte(val >> 48)\n\tbuf[offset+3] = byte(val >> 40)\n\tbuf[offset+4] = byte(val >> 32)\n\tbuf[offset+5] = byte(val >> 24)\n\tbuf[offset+6] = byte(val >> 16)\n\tbuf[offset+7] = byte(val >> 8)\n\tbuf[offset+8] = byte(val & 0xff)\n\treturn offset + 9\n}\n\nfunc encodeUint(buf []byte, offset int, val uint) int {\n\tswitch val {\n\tcase val & 0xff: \/\/ uint8\n\t\tbuf[offset] = byte(0xcc)\n\t\tbuf[offset+1] = byte(val)\n\t\toffset += 2\n\tcase val & 0xffff: \/\/ uint16\n\t\tbuf[offset] = byte(0xcd)\n\t\tbuf[offset+1] = byte(val >> 8)\n\t\tbuf[offset+2] = byte(val & 0xff)\n\t\toffset += 3\n\tcase val & 0xffffffff: \/\/ uint32\n\t\tbuf[offset] = byte(0xce)\n\t\tbuf[offset+1] = byte(val >> 24)\n\t\tbuf[offset+2] = byte(val >> 16)\n\t\tbuf[offset+3] = byte(val >> 8)\n\t\tbuf[offset+4] = byte(val & 0xff)\n\t\toffset += 5\n\tdefault: \/\/ uint64\n\t\tbuf[offset] = byte(0xcf)\n\t\tbuf[offset+1] = byte(val >> 56)\n\t\tbuf[offset+2] = byte(val >> 48)\n\t\tbuf[offset+3] = byte(val >> 40)\n\t\tbuf[offset+4] = byte(val >> 32)\n\t\tbuf[offset+5] = byte(val >> 24)\n\t\tbuf[offset+6] = byte(val >> 16)\n\t\tbuf[offset+7] = byte(val >> 8)\n\t\tbuf[offset+8] = byte(val & 0xff)\n\t\toffset += 9\n\t}\n\treturn offset\n}\n\n\/\/ Encodes @val as a bigendian unsigned integer in buffer @buf\n\/\/ starting at offset @offset.

In this case images and metadata are not exported.\nWhen writing to a directory, existing files will be overwritten.\n\nThe program exits with non-zero code if at least one src could not be exported.\n\n## Serve command\n\nServe provides a simple web server for viewing exported codelabs.\nIt takes no arguments and presents the current directory contents.\nClicking on a directory representing an exported codelab will load\nall the required dependencies and render the generated codelab as\nit would appear in production.\n\nThe serve command takes a -addr host:port option, to specify the\ndesired hostname or IP address and port number to bind to.\n\n## Update command\n\nUpdate scans one or more 'src' local directories for codelab.json metadata\nfiles, recursively. A directory containing the metadata file is expected\nto be a codelab previously created with the export command.\n\nCurrent directory is assumed if no 'src' argument is given.\n\nEach found codelab is then re-exported using parameters from the metadata file.\nUnused codelab assets will be deleted, as well as the entire codelab directory,\nif codelab ID has changed since last update or export.\n\nIn the latter case, where codelab ID has changed, the new directory\nwill be placed alongside the old one. In other words, it will have the same ancestor\nas the old one.\n\nWhile -prefix and -ga can override existing codelab metadata, the other\narguments have no effect during update.\n\nThe program does not follow symbolic links and exits with non-zero code\nif no metadata found or at least one src could not be updated.\n\n## Flags\n\n`\n<commit_msg>Add claat main command doc comment<commit_after>\/\/ Copyright 2018 Google Inc.

In this case images and metadata are not exported.\nWhen writing to a directory, existing files will be overwritten.\n\nThe program exits with non-zero code if at least one src could not be exported.\n\n## Serve command\n\nServe provides a simple web server for viewing exported codelabs.\nIt takes no arguments and presents the current directory contents.\nClicking on a directory representing an exported codelab will load\nall the required dependencies and render the generated codelab as\nit would appear in production.\n\nThe serve command takes a -addr host:port option, to specify the\ndesired hostname or IP address and port number to bind to.\n\n## Update command\n\nUpdate scans one or more 'src' local directories for codelab.json metadata\nfiles, recursively. A directory containing the metadata file is expected\nto be a codelab previously created with the export command.\n\nCurrent directory is assumed if no 'src' argument is given.\n\nEach found codelab is then re-exported using parameters from the metadata file.\nUnused codelab assets will be deleted, as well as the entire codelab directory,\nif codelab ID has changed since last update or export.\n\nIn the latter case, where codelab ID has changed, the new directory\nwill be placed alongside the old one. In other words, it will have the same ancestor\nas the old one.\n\nWhile -prefix and -ga can override existing codelab metadata, the other\narguments have no effect during update.\n\nThe program does not follow symbolic links and exits with non-zero code\nif no metadata found or at least one src could not be updated.\n\n## Flags\n\n`\n<|endoftext|>"}

The following\n\/\/ sections provide more in depth commentary.\n\/\/\n{{.Overview}}\n\/\/{{end}}\n{{define \"interfaces\"}}\/\/ The Matrix Interfaces\n\/\/\n\/\/ The Matrix interface is the common link between the concrete types. The Matrix\n\/\/ interface is defined by three functions: Dims, which returns the dimensions\n\/\/ of the Matrix, At, which returns the element in the specified location, and\n\/\/ T for returning a Transpose (discussed later). All of the concrete types can\n\/\/ perform these behaviors and so implement the interface. Methods and functions\n\/\/ are designed to use this interface, so in particular the method\n\/\/  func (m *Dense) Mul(a, b Matrix)\n\/\/ constructs a *Dense from the result of a multiplication with any Matrix types,\n\/\/ not just *Dense. Where more restrictive requirements must be met, there are also the\n\/\/ Symmetric and Triangular interfaces. For example, in\n\/\/  func (s *SymDense) AddSym(a, b Symmetric)\n\/\/ the Symmetric interface guarantees a symmetric result.\n\/\/\n\/\/ Transposes\n\/\/\n\/\/ The T method is used for transposition. For example, c.Mul(a.T(), b) computes\n\/\/ c = a^T * b. The {{if .ExamplePackage}}{{.ExamplePackage}}{{else}}{{.Name}}{{end}} types implement this method using an implicit transpose —\n\/\/ see the Transpose type for more details. Note that some operations have a\n\/\/ transpose as part of their definition, as in *SymDense.SymOuterK.\n\/\/{{end}}\n{{define \"factorization\"}}\/\/ Matrix Factorization\n\/\/\n\/\/ Matrix factorizations, such as the LU decomposition, typically have their own\n\/\/ specific data storage, and so are each implemented as a specific type. The\n\/\/ factorization can be computed through a call to Factorize\n\/\/  var lu {{if .ExamplePackage}}{{.ExamplePackage}}{{else}}{{.Name}}{{end}}.LU\n\/\/  lu.Factorize(a)\n\/\/ The elements of the factorization can be extracted through methods on the\n\/\/ appropriate type, i.e. *TriDense.LFromLU and *TriDense.UFromLU. Alternatively,\n\/\/ they can be used directly, as in *Dense.SolveLU. Some factorizations can be\n\/\/ updated directly, without needing to update the original matrix and refactorize,\n\/\/ as in *LU.RankOne.\n\/\/{{end}}\n{{define \"blas\"}}\/\/ BLAS and LAPACK\n\/\/\n\/\/ BLAS and LAPACK are the standard APIs for linear algebra routines. Many\n\/\/ operations in {{if .Description}}{{.Description}}{{else}}{{.Name}}{{end}} are implemented using calls to the wrapper functions\n\/\/ in gonum\/blas\/{{.BLAS|alts}} and gonum\/lapack\/{{.LAPACK|alts}}. By default, {{.BLAS|join \"\/\"}} and\n\/\/ {{.LAPACK|join \"\/\"}} call the native Go implementations of the routines. Alternatively,\n\/\/ it is possible to use C-based implementations of the APIs through the respective\n\/\/ cgo packages and \"Use\" functions. The Go implementation of LAPACK makes calls\n\/\/ through {{.BLAS|join \"\/\"}}, so if a cgo BLAS implementation is registered, the {{.LAPACK|join \"\/\"}}\n\/\/ calls will be partially executed in Go and partially executed in C.\n\/\/{{end}}\n{{define \"switching\"}}\/\/ Type Switching\n\/\/\n\/\/ The Matrix abstraction enables efficiency as well as interoperability. Go's\n\/\/ type reflection capabilities are used to choose the most efficient routine\n\/\/ given the specific concrete types. For example, in\n\/\/  c.Mul(a, b)\n\/\/ if a and b both implement RawMatrixer, that is, they can be represented as a\n\/\/ {{.BLAS|alts}}.General, {{.BLAS|alts}}.Gemm (general matrix multiplication) is called, while\n\/\/ instead if b is a RawSymmetricer {{.BLAS|alts}}.Symm is used (general-symmetric\n\/\/ multiplication), and if b is a *Vector {{.BLAS|alts}}.Gemv is used.\n\/\/\n\/\/ There are many possible type combinations and special cases. No specific guarantees\n\/\/ are made about the performance of any method, and in particular, note that an\n\/\/ abstract matrix type may be copied into a concrete type of the corresponding\n\/\/ value. If there are specific special cases that are needed, please submit a\n\/\/ pull-request or file an issue.\n\/\/{{end}}\n{{define \"invariants\"}}\/\/ Invariants\n\/\/\n\/\/ Matrix input arguments to functions are never directly modified. If an operation\n\/\/ changes Matrix data, the mutated matrix will be the receiver of a function.\n\/\/\n\/\/ For convenience, a matrix may be used as both a receiver and as an input, e.g.\n\/\/  a.Pow(a, 6)\n\/\/  v.SolveVec(a.T(), v)\n\/\/ though in many cases this will cause an allocation (see Element Aliasing).\n\/\/ An exception to this rule is Copy, which does not allow a.Copy(a.T()).\n\/\/{{end}}\n{{define \"aliasing\"}}\/\/ Element Aliasing\n\/\/\n\/\/ Most methods in {{if .Description}}{{.Description}}{{else}}{{.Name}}{{end}} modify receiver data. It is forbidden for the modified\n\/\/ data region of the receiver to overlap the used data area of the input\n\/\/ arguments. The exception to this rule is when the method receiver is equal to one\n\/\/ of the input arguments, as in the a.Pow(a, 6) call above, or its implicit transpose.\n\/\/\n\/\/ This prohibition is to help avoid subtle mistakes when the method needs to read\n\/\/ from and write to the same data region. There are ways to make mistakes using the\n\/\/ {{.Name}} API, and {{.Name}} functions will detect and complain about those.\n\/\/ There are many ways to make mistakes by excursion from the {{.Name}} API via\n\/\/ interaction with raw matrix values.\n\/\/\n\/\/ If you need to read the rest of this section to understand the behavior of\n\/\/ your program, you are being clever. Don't be clever. If you must be clever,\n\/\/ {{.BLAS|join \"\/\"}} and {{.LAPACK|join \"\/\"}} may be used to call the behavior directly.\n\/\/\n\/\/ {{if .Description}}{{.Description|sentence}}{{else}}{{.Name}}{{end}} will use the following rules to detect overlap between the receiver and one\n\/\/ of the inputs:\n\/\/  - the input implements one of the Raw methods, and\n\/\/  - the Raw type matches that of the receiver, and\n\/\/  - the address ranges of the backing data slices overlap, and\n\/\/  - the strides differ or there is an overlap in the used data elements.\n\/\/ If such an overlap is detected, the method will panic.\n\/\/\n\/\/ The following cases will not panic:\n\/\/  - the data slices do not overlap,\n\/\/  - there is pointer identity between the receiver and input values after\n\/\/    the value has been untransposed if necessary.\n\/\/\n\/\/ {{if .Description}}{{.Description|sentence}}{{else}}{{.Name}}{{end}} will not attempt to detect element overlap if the input does not implement a\n\/\/ Raw method, or if the Raw method differs from that of the receiver except when a\n\/\/ conversion has occurred through a {{.Name}} API function.

You may use apt_validate to make sure your bags\nare valid before uploading. The bags you upload will go into the\nreceiving bucket specified in your config file.\n\nExamples:\n    apt_upload -config=aptrust.conf archive1.tar archive2.tar\n    apt_upload -config=aptrust.conf ~\/my_data\/*.tar\n    apt_upload -config=aptrust.conf -v ~\/my_data\/*\n\nWhen using the * pattern, as in the second and third examples above,\napt_upload will not recurse into sub directories. It will upload\nfiles only, and will skip directories.\n\nYour config file should include the following name-value pairs,\nseparated by an equal sign. The file may also include comment lines,\nwhich begin with a hash mark. Here's an example config file:\n\n# Config for apt_upload and apt_download\nAwsAccessKeyId = 123456789XYZ\nAwsSecretAccessKey = THIS KEY INCLUDES SPACES AND DOES NOT NEED QUOTES\nReceivingBucket = 'aptrust.receive.test.edu'\nRestorationBucket = \"aptrust.restore.test.edu\"\n\nIf you prefer not to put your AWS keys in the config file, you can\nput them into environment variables called AWS_ACCESS_KEY_ID\nand AWS_SECRET_ACCESS_KEY.\n\nReceivingBucket is the name of the bucket into which you will upload\nbags for ingest. The RestorationBucket is the bucket from which you\nwill download bags that you have restored.\n\napt_upload prints all output to stdout.

You may use apt_validate to make sure your bags\nare valid before uploading. The bags you upload will go into the\nreceiving bucket specified in your config file.\n\nExamples:\n    apt_upload -config=aptrust.conf archive1.tar archive2.tar\n    apt_upload -config=aptrust.conf ~\/my_data\/*.tar\n    apt_upload -config=aptrust.conf -v ~\/my_data\/*\n\nWhen using the * pattern, as in the second and third examples above,\napt_upload will not recurse into sub directories. It will upload\nfiles only, and will skip directories.\n\nYour config file should include the following name-value pairs,\nseparated by an equal sign. The file may also include comment lines,\nwhich begin with a hash mark. Here's an example config file:\n\n# Config for apt_upload and apt_download\nAwsAccessKeyId = 123456789XYZ\nAwsSecretAccessKey = THIS KEY INCLUDES SPACES AND DOES NOT NEED QUOTES\nReceivingBucket = 'aptrust.receive.test.edu'\nRestorationBucket = \"aptrust.restore.test.edu\"\nDownloadDir = \"\/home\/josie\/downloads\"\n\nIf you prefer not to put your AWS keys in the config file, you can\nput them into environment variables called AWS_ACCESS_KEY_ID\nand AWS_SECRET_ACCESS_KEY.\n\nReceivingBucket is the name of the bucket into which you will upload\nbags for ingest. The RestorationBucket is the bucket from which you\nwill download bags that you have restored.\n\napt_upload prints all output to stdout. Typical output includes the\nresult of the file upload (OK or ERROR). Failed uploads should show\na description of the error.

While there will be many similarities in how the Fixity\n\/\/ blockchain uses immutability and history, there will also be many\n\/\/ differences from popular blockchains.\n\/\/\n\/\/ A blockchain in Fixity serves as a ledger for what content exists\n\/\/ on a distributed Fixity network. If a hash address cannot be found\n\/\/ within one of the Blocks on the blockchain, such as the hash of\n\/\/ a Content, Blob or Chunk, then it is considered available for\n\/\/ garbage collection and will be removed.\n\/\/\n\/\/ The Fixity blockchain consists of three main parts: The Block number,\n\/\/ the PreviousBlockHash and some data effectively giving the Block a\n\/\/ \"type\".\n\/\/\n\/\/ The Block number is an ever incrementing value and with the help of\n\/\/ PreviousBlockHash it provides a way for distributed nodes to achieve\n\/\/ eventual consensus.\n\/\/\n\/\/ The PreviousBlockHash provides a way to track the entire blockchain\n\/\/ from the Head() Block. It also provides a way for the blockchain itself\n\/\/ to be mutable, in an immutable environment. More on mutability soon.\n\/\/\n\/\/ The Block type is the reason why the block exists. It may have added\n\/\/ Content, removed Content, mutated the chain, etc.\n\/\/\n\/\/ Mutability of the blockchain is achieved by appending new blocks that\n\/\/ skip one or more blocks in their PreviousBlockHash. For example, with\n\/\/ a blockchain of 5 blocks, Block 6 could be written with a\n\/\/ PreviousBlockHash set to the hash of Block 4. Since Block 6 is the head,\n\/\/ traversing the blockchain would look like: Block 6 -> Block 4 -> Block 3\n\/\/ and so on. Note that Blocks start with 0 index, but for these examples\n\/\/ we're not using zero index.\n\/\/\n\/\/ To achieve mutability on blocks that aren't currently the Head()\n\/\/ as Block 5 was in the previous example, all Blocks from the target\n\/\/ Block to the Head() must be rewritten to the blockchain. In order.\n\/\/ This means that removing old blocks can be costly and slow.\n\/\/\n\/\/ Fixity strives to keep the ledger as a trustable and easy to verify\n\/\/ chain. An alternative to block skipping would be to write a content\n\/\/ deletion block, essentially writing to the ledger that content is\n\/\/ to be garbage collected. However, verifying the ever growing blockchain\n\/\/ would mean needing to reference these deletion blocks frequently to know\n\/\/ what content should and shouldn't be looked into. In otherwords,\n\/\/ content on the blockchain may have a deletion block for it further up\n\/\/ the chain, so verifying content of the ledger becomes difficult.\n\/\/\n\/\/ The chosen method of content skipping does most of the difficult work\n\/\/ up front and results in a very clean ledger. It does this at the cost\n\/\/ of needing to complicate the removal\/skipping process.\n\/\/\n\/\/ This interface focuses on all of the above functionality.\ntype Blockchain interface {\n\t\/\/ \/\/ AppendBlocks locks the store and writes the given blocks in order.\n\t\/\/ \/\/\n\t\/\/ \/\/ The field PreviousBlockHash's value of all blocks *must* be empty.\n\t\/\/ \/\/\n\t\/\/ \/\/ The returned Block array will contain the new hashes of the given\n\t\/\/ \/\/ blocks.\n\t\/\/ AppendBlocks(appendTo Block, blocks []Block) ([]Block, error)\n\n\t\/\/ AppendContent creates a new block with the given content.\n\t\/\/\n\t\/\/ If the block is the same as the current Head() the blockchain must\n\t\/\/ not be progressed.\n\tAppendContent(Content) (Block, error)\n\n\t\/\/ Head returns the latest block in the blockchain.\n\tHead() (Block, error)\n\n\t\/\/ \/\/ SkipBlock removes the given block from the blockchain.\n\t\/\/ SkipBlock(Block) ([]Block, error)\n}\n\n\/\/ Block serves as a ledger for mutations of the fixity datastore.\n\/\/\n\/\/ Each block stores an always incrementing Block number and a hash of\n\/\/ the previous block in the chain. These two fields allow a fixity\n\/\/ store to be iterated through the always appending history.\n\/\/\n\/\/ While the history is always appending, previous blocks may be skipped,\n\/\/ effectively removing them from the history of the blockchain.

In otherwords,\n\/\/ content on the blockchain may have a deletion block for it further up\n\/\/ the chain, so verifying content of the ledger becomes difficult.\n\/\/\n\/\/ The chosen method of content skipping does most of the difficult work\n\/\/ up front and results in a very clean ledger. It does this at the cost\n\/\/ of needing to complicate the removal\/skipping process.\n\/\/\n\/\/ This interface focuses on all of the above functionality.\ntype Blockchain interface {\n\t\/\/ \/\/ AppendBlocks locks the store and writes the given blocks in order.\n\t\/\/ \/\/\n\t\/\/ \/\/ The field PreviousBlockHash's value of all blocks *must* be empty.\n\t\/\/ \/\/\n\t\/\/ \/\/ The returned Block array will contain the new hashes of the given\n\t\/\/ \/\/ blocks.\n\t\/\/ AppendBlocks(appendTo Block, blocks []Block) ([]Block, error)\n\n\t\/\/ AppendContent creates a new block with the given content.\n\t\/\/\n\t\/\/ If the block is the same as the current Head() the blockchain must\n\t\/\/ not be progressed.\n\tAppendContent(Content) (Block, error)\n\n\t\/\/ Head returns the latest block in the blockchain.\n\tHead() (Block, error)\n\n\t\/\/ \/\/ SkipBlock removes the given block from the blockchain.\n\t\/\/ SkipBlock(Block) ([]Block, error)\n}\n\n\/\/ Block serves as a ledger for mutations of the fixity datastore.\n\/\/\n\/\/ Each block stores an always incrementing Block number and a hash of\n\/\/ the previous block in the chain. These two fields allow a fixity\n\/\/ store to be iterated through the always appending history.\n\/\/\n\/\/ While the history is always appending, previous blocks may be skipped,\n\/\/ effectively removing them from the history of the blockchain.

STM makes it easy to perform arbitrarily complex operations in an\natomic fashion. One of its primary advantages over traditional locking is that\nSTM transactions are composable, whereas locking functions are not -- the\ncomposition will either deadlock or release the lock between functions (making\nit non-atomic).\n\nTo begin, create an STM object that wraps the data you want to access\nconcurrently.\n\n\tx := stm.NewVar(3)\n\nYou can then use the Atomically method to atomically read and\/or write the the\ndata. This code atomically decrements x:\n\n\tstm.Atomically(func(tx *stm.Tx) {\n\t\tcur := tx.Get(x).(int)\n\t\ttx.Set(x, cur-1)\n\t})\n\nAn important part of STM transactions is retrying. At any point during the\ntransaction, you can call tx.Retry(), which will abort the transaction, but\nnot cancel it entirely. The call to Atomically will block until another call\nto Atomically finishes, at which point the transaction will be rerun.\nSpecifically, one of the values read by the transaction (via tx.Get) must be\nupdated before the transaction will be rerun. As an example, this code will\ntry to decrement x, but will block as long as x is zero:\n\n\tstm.Atomically(func(tx *stm.Tx) {\n\t\tcur := tx.Get(x).(int)\n\t\tif cur == 0 {\n\t\t\ttx.Retry()\n\t\t}\n\t\ttx.Set(x, cur-1)\n\t})\n\nInternally, tx.Retry simply calls panic(stm.Retry). Panicking with any other\nvalue will cancel the transaction; no values will be changed. However, it is\nthe responsibility of the caller to catch such panics.\n\nMultiple transactions can be composed using Select. If the first transaction\ncalls Retry, the next transaction will be run, and so on. If all of the\ntransactions call Retry, the call will block and the entire selection will be\nretried. For example, this code implements the \"decrement-if-nonzero\"\ntransaction above, but for two values. It will first try to decrement x, then\ny, and block if both values are zero.\n\n\tfunc dec(v *stm.Var) {\n\t\treturn func(tx *stm.Tx) {\n\t\t\tcur := tx.Get(v).(int)\n\t\t\tif cur == 0 {\n\t\t\t\ttx.Retry()\n\t\t\t}\n\t\t\ttx.Set(v, cur-1)\n\t\t}\n\t}\n\n\t\/\/ Note that Select does not perform any work itself, but merely\n\t\/\/ returns a transaction function.\n\tstm.Atomically(stm.Select(dec(x), dec(y)))\n\nAn important caveat: transactions must be idempotent (they should have the\nsame effect every time they are invoked). This is because a transaction may be\nretried several times before successfully completing, meaning its side effects\nmay execute more than once. This will almost certainly cause incorrect\nbehavior. One common way to get around this is to build up a list of impure\noperations inside the transaction, and then perform them after the transaction\ncompletes.\n\nThe stm API tries to mimic that of Haskell's Control.Concurrent.STM, but this\nis not entirely possible due to Go's type system; we are forced to use\ninterface{} and type assertions.

Integers are printed unsigned if they have unsigned type.\n\tSimilarly, there is no need to specify the size of the operand (int8, int64).\n\n\tWidth is specified by an optional decimal number immediately following the verb.\n\tIf absent, the width is whatever is necessary to represent the value.\n\tPrecision is specified after the (optional) width by a period followed by a\n\tdecimal number. If no period is present, a default precision is used.\n\tA period with no following number specifies a precision of zero.\n\tExamples:\n\t\t%f:    default width, default precision\n\t\t%9f    width 9, default precision\n\t\t%.2f   default width, precision 2\n\t\t%9.2f  width 9, precision 2\n\t\t%9.f   width 9, precision 0\n\n\tWidth and precision are measured in units of Unicode code points.\n\t(This differs from C's printf where the units are numbers\n\tof bytes.) 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 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\tFor floating-point 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 complex numbers, the width and precision apply to the two\n\tcomponents independently and the result is parenthsized, so %f applied\n\tto 1.2+3.4i produces (1.200000+3.400000i).\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\tExcept when printed using the the verbs %T and %p, special\n\tformatting considerations apply for operands that implement\n\tcertain interfaces. In order of application:\n\n\t1. If an operand implements the Formatter interface, it will\n\tbe invoked. Formatter provides fine control of formatting.\n\n\t2. If the %v verb is used with the # flag (%#v) and the operand\n\timplements the GoStringer interface, that will be invoked.\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 apply:\n\n\t3.

If an operand implements method String() string, that method\n\twill be invoked to convert the object to a string, which will then\n\tbe formatted as required by the verb (if any).\n\n\tFor compound operands such as slices and structs, the format\n\tapplies to the elements of each operand, recursively, not to the\n\toperand as a whole. Thus %q will quote each element of a slice\n\tof strings, and %6.2f will control formatting for each element\n\tof a floating-point array.\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.

Integers are printed unsigned if they have unsigned type.\n\tSimilarly, there is no need to specify the size of the operand (int8, int64).\n\n\tWidth is specified by an optional decimal number immediately following the verb.\n\tIf absent, the width is whatever is necessary to represent the value.\n\tPrecision is specified after the (optional) width by a period followed by a\n\tdecimal number. If no period is present, a default precision is used.\n\tA period with no following number specifies a precision of zero.\n\tExamples:\n\t\t%f:    default width, default precision\n\t\t%9f    width 9, default precision\n\t\t%.2f   default width, precision 2\n\t\t%9.2f  width 9, precision 2\n\t\t%9.f   width 9, precision 0\n\n\tWidth and precision are measured in units of Unicode code points.\n\t(This differs from C's printf where the units are numbers\n\tof bytes.) 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 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\tFor floating-point 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 complex numbers, the width and precision apply to the two\n\tcomponents independently and the result is parenthsized, so %f applied\n\tto 1.2+3.4i produces (1.200000+3.400000i).\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\tExcept when printed using the verbs %T and %p, special\n\tformatting considerations apply for operands that implement\n\tcertain interfaces. In order of application:\n\n\t1. If an operand implements the Formatter interface, it will\n\tbe invoked. Formatter provides fine control of formatting.\n\n\t2. If the %v verb is used with the # flag (%#v) and the operand\n\timplements the GoStringer interface, that will be invoked.\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 apply:\n\n\t3. If an operand implements the error interface, the Error method\n\twill be invoked to convert the object to a string, which will then\n\tbe formatted as required by the verb (if any).\n\n\t4. If an operand implements method String() string, that method\n\twill be invoked to convert the object to a string, which will then\n\tbe formatted as required by the verb (if any).\n\n\tFor compound operands such as slices and structs, the format\n\tapplies to the elements of each operand, recursively, not to the\n\toperand as a whole. Thus %q will quote each element of a slice\n\tof strings, and %6.2f will control formatting for each element\n\tof a floating-point array.\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.

This program will get your\nAWS credentials from the config file, if it can find one. Otherwise,\nit will get your AWS credentials from the environment variables\n\"AWS_ACCESS_KEY_ID\" and \"AWS_SECRET_ACCESS_KEY\". If it can't find your\nAWS credentials, the upload will fail.\n\n-config is the optional path to your APTrust partner config file.\n\t\tIf you omit this, the uploader uses the config at\n\t\t~\/.aptrust_partner.conf (Mac\/Linux) or %HOMEPATH%\\.aptrust_partner.conf\n\t\t(Windows) if that file exists. The config file should contain\n\t\tyour AWS keys, and the locations of your receiving bucket.\n\t\tFor info about what should be in your config file, see\n\t\thttps:\/\/sites.google.com\/a\/aptrust.org\/member-wiki\/partner-tools\n\n-region is the S3 region to connect to. This defaults to us-east-1. You\n\t\tgenerally should not have to set this for APTrust uploads,\n\t\tbut you may set it on the command line to upload non-APTrust\n\t\tfiles from your own buckets.\n\n-bucket is the name of the S3 bucket to upload to. If this is not\n\t\tspecified on the command line, apt_upload will use the\n\t\trestoration bucket specified in your APTrust partner config file.\n\t\tSee the -config option for more info.\n\n-key    if you want your uploaded file to have a different name in S3,\n\t\tspecify that here. If you upload a file from \/home\/joy\/my_file.txt,\n\t\tit will be put into your S3 bucket with the name \"my_file.txt\".\n\t\tSetting the -key option allows you to override that. So if\n\t\t-key='file_001.txt', \/home\/joy\/my_file.txt will be saved to your\n\t\tS3 bucket with the name file_001.txt.\n\n-contentType is the optional content type of the file you're uploading.\n\t\tIf you choose to specify this, it should be in mime type format.\n\t\tFor example, \"image\/jpeg\" or \"text\/plain\". You typically don't\n\t\tneed to set this. If left unset, this usually defaults to something\n\t\tgeneric and unhelpful like \"application\/octet-stream\".\n\t\tIf you want to set it, you'll find a full list of mime types at\n\t\thttps:\/\/developer.mozilla.org\/en-US\/docs\/Web\/HTTP\/Basics_of_HTTP\/MIME_types\/Complete_list_of_MIME_types\n\n-format is the format of the output printed to STDOUT when the upload\n\t\tis complete. Options are 'text' and 'json', and the default is\n\t\t'text'.\n\n-metadata allows you to specify optional metadata, in json format, to be\n\t\tsaved in S3 with your file. A metadata json string should look\n\t\tlike this:\n\n\t\t-metadata='{\"Bag\":\"my_bag\",\"Bagpath\":\"data\/Image001.tif\",\"Institution\":\"virginia.edu\",\"Md5\":\"12345\",\"Sha256\":\"54321\"}'\n\nExamples:\n\n1.

This program will get your\nAWS credentials from the config file, if it can find one. Otherwise,\nit will get your AWS credentials from the environment variables\n\"AWS_ACCESS_KEY_ID\" and \"AWS_SECRET_ACCESS_KEY\". If it can't find your\nAWS credentials, the upload will fail.\n\n-config is the optional path to your APTrust partner config file.\n\t\tIf you omit this, the uploader uses the config at\n\t\t~\/.aptrust_partner.conf (Mac\/Linux) or %HOMEPATH%\\.aptrust_partner.conf\n\t\t(Windows) if that file exists. The config file should contain\n\t\tyour AWS keys, and the locations of your receiving bucket.\n\t\tFor info about what should be in your config file, see\n\t\thttps:\/\/sites.google.com\/a\/aptrust.org\/member-wiki\/partner-tools\n\n-region is the S3 region to connect to. This defaults to us-east-1. You\n\t\tgenerally should not have to set this for APTrust uploads,\n\t\tbut you may set it on the command line to upload non-APTrust\n\t\tfiles from your own buckets.\n\n-bucket is the name of the S3 bucket to upload to. If this is not\n\t\tspecified on the command line, apt_upload will use the\n\t\trestoration bucket specified in your APTrust partner config file.\n\t\tSee the -config option for more info.\n\n-key    if you want your uploaded file to have a different name in S3,\n\t\tspecify that here. If you upload a file from \/home\/joy\/my_file.txt,\n\t\tit will be put into your S3 bucket with the name \"my_file.txt\".\n\t\tSetting the -key option allows you to override that. So if\n\t\t-key='file_001.txt', \/home\/joy\/my_file.txt will be saved to your\n\t\tS3 bucket with the name file_001.txt.\n\n-contentType is the optional content type of the file you're uploading.\n\t\tIf you choose to specify this, it should be in mime type format.\n\t\tFor example, \"image\/jpeg\" or \"text\/plain\". You typically don't\n\t\tneed to set this. If left unset, this usually defaults to something\n\t\tgeneric and unhelpful like \"application\/octet-stream\".\n\t\tIf you want to set it, you'll find a full list of mime types at\n\t\thttps:\/\/developer.mozilla.org\/en-US\/docs\/Web\/HTTP\/Basics_of_HTTP\/MIME_types\/Complete_list_of_MIME_types\n\n-format is the format of the output printed to STDOUT when the upload\n\t\tis complete. Options are 'text' and 'json', and the default is\n\t\t'text'.\n\n-metadata allows you to specify optional metadata, in json format, to be\n\t\tsaved in S3 with your file. A metadata json string should look\n\t\tlike this:\n\n\t\t-metadata='{\"Bag\":\"my_bag\",\"Bagpath\":\"data\/Image001.tif\",\"Institution\":\"virginia.edu\",\"Md5\":\"12345\",\"Sha256\":\"54321\"}'\n\nExamples:\n\n1. Upload item \"\/home\/joy\/my_bag.tar\" to your receiving bucket, using your\n   default APTrust partner config file in ~\/.aptrust_partner.conf (Mac\/Linux)\n   or %HOMEPATH%\\.aptrust_partner.conf\n\n   apt_upload \/home\/joy\/my_bag.tar\n\n2. Upload item \"\/home\/joy\/my_bag.tar\" to your receiving bucket, using a\n   custom APTrust partner config file\n\n   apt_upload -config=\"\/home\/joy\/aptrust_config.txt\" \/home\/joy\/my_bag.tar\n\n3.

But the new\n\/\/ `sigs.k8s.io\/controller-tools\/controller-gen` command doesn't; it just\n\/\/ has a small number of \"+kubebuilder:\" magic comments (\"markers\") that we\n\/\/ can use to influence the schema it generates.\n\/\/\n\/\/ So, for example, we'd like to define the AmbassadorID schema as:\n\/\/\n\/\/    oneOf:\n\/\/    - type: \"string\"\n\/\/    - type: \"array\"\n\/\/    items:             # only matters if type=array\n\/\/      type: \"string\"\n\/\/\n\/\/ but if we're going to use just vanilla controller-gen, we're forced to\n\/\/ be dumb and say `+kubebuilder:validation:Type=\"\"`, to define its schema\n\/\/ as\n\/\/\n\/\/    # no `type:` setting because of the +kubebuilder marker\n\/\/    items:\n\/\/      type: \"string\"  # because of the raw type\n\/\/\n\/\/ and then kubectl and\/or the apiserver won't be able to validate\n\/\/ AmbassadorID, because it won't be validated until we actually go to\n\/\/ UnmarshalJSON it when it makes it to Ambassador.

If a hash address cannot be found\n\/\/ within one of the Blocks on the blockchain, such as the hash of\n\/\/ a Content, Blob or Chunk, then it is considered available for\n\/\/ garbage collection and will be removed.\n\/\/\n\/\/ The Fixity blockchain consists of three main parts: The Block number,\n\/\/ the PreviousBlockHash and some data effectively giving the Block a\n\/\/ \"type\".\n\/\/\n\/\/ The Block number is an ever incrementing value and with the help of\n\/\/ PreviousBlockHash it provides a way for distributed nodes to achieve\n\/\/ eventual consensus.\n\/\/\n\/\/ The PreviousBlockHash provides a way to track the entire blockchain\n\/\/ from the Head() Block. It also provides a way for the blockchain itself\n\/\/ to be mutable, in an immutable environment. More on mutability soon.\n\/\/\n\/\/ The Block type is the reason why the block exists. It may have added\n\/\/ Content, removed Content, mutated the chain, etc.\n\/\/\n\/\/ Mutability of the blockchain is achieved by appending new blocks that\n\/\/ skip one or more blocks in their PreviousBlockHash. For example, with\n\/\/ a blockchain of 5 blocks, Block 6 could be written with a\n\/\/ PreviousBlockHash set to the hash of Block 4. Since Block 6 is the head,\n\/\/ traversing the blockchain would look like: Block 6 -> Block 4 -> Block 3\n\/\/ and so on. Note that Blocks start with 0 index, but for these examples\n\/\/ we're not using zero index.\n\/\/\n\/\/ To achieve mutability on blocks that aren't currently the Head()\n\/\/ as Block 5 was in the previous example, all Blocks from the target\n\/\/ Block to the Head() must be rewritten to the blockchain. In order.\n\/\/ This means that removing old blocks can be costly and slow.\n\/\/\n\/\/ Fixity strives to keep the ledger as a trustable and easy to verify\n\/\/ chain. An alternative to block skipping would be to write a content\n\/\/ deletion block, essentially writing to the ledger that content is\n\/\/ to be garbage collected. However, verifying the ever growing blockchain\n\/\/ would mean needing to reference these deletion blocks frequently to know\n\/\/ what content should and shouldn't be looked into. In otherwords,\n\/\/ content on the blockchain may have a deletion block for it further up\n\/\/ the chain, so verifying content of the ledger becomes difficult.\n\/\/\n\/\/ The chosen method of content skipping does most of the difficult work\n\/\/ up front and results in a very clean ledger. It does this at the cost\n\/\/ of needing to complicate the removal\/skipping process.\n\/\/\n\/\/ This interface focuses on all of the above functionality.\ntype Blockchain interface {\n\t\/\/ AppendBlocks locks the store and writes the given blocks in order.\n\t\/\/\n\t\/\/ The field PreviousBlockHash's value of all blocks *must* be empty.\n\t\/\/\n\t\/\/ The returned Block array will contain the new hashes of the given\n\t\/\/ blocks.\n\tAppendBlocks(appendTo Block, blocks []Block) ([]Block, error)\n\n\t\/\/ Head returns the latest block in the blockchain.\n\tHead() (Block, error)\n\n\t\/\/ SkipBlock removes the given block from the blockchain.\n\tSkipBlock(Block) ([]Block, error)\n}\n\n\/\/ Block serves as a ledger for mutations of the fixity datastore.\n\/\/\n\/\/ Each block stores an always incrementing Block number and a hash of\n\/\/ the previous block in the chain. These two fields allow a fixity\n\/\/ store to be iterated through the always appending history.\n\/\/\n\/\/ While the history is always appending, previous blocks may be skipped,\n\/\/ effectively removing them from the history of the blockchain. This is\n\/\/ done by writing a new block whose PreviousBlockHash value skips one or\n\/\/ more previous blocks in the chain.\ntype Block struct {\n\t\/\/ Block is the ever incrementing block number for this block.\n\t\/\/\n\t\/\/ Each block will be incremented from the previous block.\n\tBlock int `json:\"block\"`\n\n\t\/\/ PreviousBlockHash is the hash of the block that came before this.\n\t\/\/\n\t\/\/ Note that the blockchain itself is mutable, such that the\n\t\/\/ PreviousBlockHash isn't guaranteed to have the block number of Block-1.\n\t\/\/ If a block was skipped, the block numbers may differ.\n\t\/\/\n\t\/\/ See FixityBlockchain.SkipBlock for more information on block skipping\n\t\/\/ and implications of that.\n\tPreviousBlockHash string `json:\"previousBlockHash\"`\n\n\t\/\/ Skip contains Skip data and makes this Block a Skip Block.\n\tSkip *Skip `json:\"skip,omitempty\"`\n\n\t\/\/ ContentHash contains the ContentHash and makes this block a Content block.\n\tContentHash string `json:\"cotentHash,omitempty\"`\n\n\t\/\/ BlockHash is the hash of the Block itself, provided by Fixity.\n\tBlockHash string `json:\"-\"`\n\n\t\/\/ Store allows block method(s) to load previous blocks and content.\n\tStore Store `json:\"-\"`\n}\n\n\/\/ Skip blocks provide information about the block that was skipped.\ntype Skip struct {\n\t\/\/ BlockHash of the block to be skipped.\n\tBlockHash string `json:\"blockHash\"`\n}\n\n\/\/ Content stores blob, index and history information for Fixity content.\ntype Content struct {\n\t\/\/ Id provides a user friendly way to reference a chain of Contents.\n\t\/\/\n\t\/\/ History of Content is tracked through the PreviousContentHash chain,\n\t\/\/ however that does not provide a clear single identity for users.\n\t\/\/ The id field allows this, can be indexed and assocoated and is\n\t\/\/ easy to conceptualize.\n\tId string `json:\"id,omitempty\"`\n\n\t\/\/ PreviousContentHash stores the previous Content for this Content.\n\t\/\/\n\t\/\/ This allows a single entity, such as a file or a database \"record\"\n\t\/\/ to be mutated through time.

It's broken up into 4 main sections:\n\/\/\n\/\/  * infrastructure: we really don't have any business touching these once\n\/\/    we've created them. They should have the rawAccess attribute set, so that\n\/\/    multiEnvRunner will consider them forbidden.\n\/\/\n\/\/  * global: these hold information external to environments. They may include\n\/\/    environment metadata, or references; but they're generally not relevant\n\/\/    from the perspective of a given environment.\n\/\/\n\/\/  * local (in opposition to global; and for want of a better term): these\n\/\/    hold information relevant *within* specific environments (machines,\n\/\/    services, relations, settings, bookkeeping, etc) and should generally be\n\/\/    read via an envStateCollection, and written via a multiEnvRunner. This is\n\/\/    the most common form of collection, and the above access should usually\n\/\/    be automatic via Database.Collection and Database.Runner.\n\/\/\n\/\/  * raw-access: there's certainly data that's a poor fit for mgo\/txn. Most\n\/\/    forms of logs, for example, will benefit both from the speedy insert and\n\/\/    worry-free bulk deletion; so raw-access collections are fine. Just don't\n\/\/    try to run transactions that reference them.\n\/\/\n\/\/ Please do not use collections not referenced here; and when adding new\n\/\/ collections, please document them, and make an effort to put them in an\n\/\/ appropriate section.\nfunc allCollections() collectionSchema {\n\treturn collectionSchema{\n\n\t\t\/\/ Infrastructure collections\n\t\t\/\/ ==========================\n\n\t\ttxnsC: {\n\t\t\t\/\/ This collection is used exclusively by mgo\/txn to record transactions.\n\t\t\tglobal:         true,\n\t\t\trawAccess:      true,\n\t\t\texplicitCreate: &mgo.CollectionInfo{},\n\t\t},\n\t\ttxnLogC: {\n\t\t\t\/\/ This collection is used by mgo\/txn to record the set of documents\n\t\t\t\/\/ affected by each successful transaction; and by state\/watcher to\n\t\t\t\/\/ generate a stream of document-resolution events that are delivered\n\t\t\t\/\/ to, and interpreted by, both state and state\/multiwatcher.\n\t\t\tglobal:    true,\n\t\t\trawAccess: true,\n\t\t\texplicitCreate: &mgo.CollectionInfo{\n\t\t\t\tCapped:   true,\n\t\t\t\tMaxBytes: txnLogSize,\n\t\t\t},\n\t\t},\n\n\t\t\/\/ ------------------\n\n\t\t\/\/ Global collections\n\t\t\/\/ ==================\n\n\t\t\/\/ This collection holds the details of the state servers hosting, well,\n\t\t\/\/ everything in state.\n\t\tstateServersC: {global: true},\n\n\t\t\/\/ This collection is used to track progress when restoring a\n\t\t\/\/ state server from backup.\n\t\trestoreInfoC: {global: true},\n\n\t\t\/\/ This collection is used by the state servers to coordinate binary\n\t\t\/\/ upgrades and schema migrations.\n\t\tupgradeInfoC: {global: true},\n\n\t\t\/\/ This collection holds a convenient representation of the content of\n\t\t\/\/ the simplestreams data source pointing to binaries required by juju.\n\t\ttoolsmetadataC: {global: true},\n\n\t\t\/\/ This collection holds environment information; in particular its\n\t\t\/\/ Life and its UUID.\n\t\tenvironmentsC: {global: true},\n\n\t\t\/\/ This collection holds user information that's not specific to any\n\t\t\/\/ one environment.\n\t\tusersC: {\n\t\t\tglobal: true,\n\t\t\tindexes: []mgo.Index{{\n\t\t\t\t\/\/ TODO(thumper): schema change to remove this index.\n\t\t\t\tKey: []string{\"name\"},\n\t\t\t}},\n\t\t},\n\n\t\t\/\/ This collection is used as a unique key restraint.
