By default, the bootstrap runs a plugin phase which\n   sets up any plugins specified, then a checkout phase which pulls down your code and then a\n   command phase that executes the specified command in the created environment.\n\n   You can run only specific phases with the --phases flag.\n\n   The bootstrap is also responsible for executing hooks around the phases.\n   See https:\/\/buildkite.com\/docs\/agent\/v3\/hooks for more details.\n\nExample:\n\n   $ eval $(curl -s -H \"Authorization: Bearer xxx\" \\\n

By default, the bootstrap runs a plugin phase which\n   sets up any plugins specified, then a checkout phase which pulls down your code and then a\n   command phase that executes the specified command in the created environment.\n\n   You can run only specific phases with the --phases flag.\n\n   The bootstrap is also responsible for executing hooks around the phases.\n   See https:\/\/buildkite.com\/docs\/agent\/v3\/hooks for more details.\n\nExample:\n\n   $ eval $(curl -s -H \"Authorization: Bearer xxx\" \\\n

Setting cgocheck=2 enables\n\texpensive checks that should not miss any errors, but will\n\tcause your program to run slower.\n\n\tefence: setting efence=1 causes the allocator to run in a mode\n\twhere each object is allocated on a unique page and addresses are\n\tnever recycled.\n\n\tgccheckmark: setting gccheckmark=1 enables verification of the\n\tgarbage collector's concurrent mark phase by performing a\n\tsecond mark pass while the world is stopped.  If the second\n\tpass finds a reachable object that was not found by concurrent\n\tmark, the garbage collector will panic.\n\n\tgcpacertrace: setting gcpacertrace=1 causes the garbage collector to\n\tprint information about the internal state of the concurrent pacer.\n\n\tgcshrinkstackoff: setting gcshrinkstackoff=1 disables moving goroutines\n\tonto smaller stacks.

Setting gcstoptheworld=2\n\talso disables concurrent sweeping after the garbage collection finishes.\n\n\tgctrace: setting gctrace=1 causes the garbage collector to emit a single line to standard\n\terror at each collection, summarizing the amount of memory collected and the\n\tlength of the pause. Setting gctrace=2 emits the same summary but also\n\trepeats each collection. The format of this line is subject to change.\n\tCurrently, it is:\n\t\tgc # @#s #%: #+#+# ms clock, #+#\/#\/#+# ms cpu, #->#-># MB, # MB goal, # P\n\twhere the fields are as follows:\n\t\tgc #        the GC number, incremented at each GC\n\t\t@#s         time in seconds since program start\n\t\t#%          percentage of time spent in GC since program start\n\t\t#+...+#     wall-clock\/CPU times for the phases of the GC\n\t\t#->#-># MB  heap size at GC start, at GC end, and live heap\n\t\t# MB goal   goal heap size\n\t\t# P         number of processors used\n\tThe phases are stop-the-world (STW) sweep termination, concurrent\n\tmark and scan, and STW mark termination.

Refer to the description of\n\tMemProfileRate for the default value.\n\n\tinvalidptr: defaults to invalidptr=1, causing the garbage collector and stack\n\tcopier to crash the program if an invalid pointer value (for example, 1)\n\tis found in a pointer-typed location. Setting invalidptr=0 disables this check.\n\tThis should only be used as a temporary workaround to diagnose buggy code.\n\tThe real fix is to not store integers in pointer-typed locations.\n\n\tsbrk: setting sbrk=1 replaces the memory allocator and garbage collector\n\twith a trivial allocator that obtains memory from the operating system and\n\tnever reclaims any memory.\n\n\tscavenge: scavenge=1 enables debugging mode of heap scavenger.\n\n\tscheddetail: setting schedtrace=X and scheddetail=1 causes the scheduler to emit\n\tdetailed multiline info every X milliseconds, describing state of the scheduler,\n\tprocessors, threads and goroutines.\n\n\tschedtrace: setting schedtrace=X causes the scheduler to emit a single line to standard\n\terror every X milliseconds, summarizing the scheduler state.\n\nThe net and net\/http packages also refer to debugging variables in GODEBUG.\nSee the documentation for those packages for details.\n\nThe GOMAXPROCS variable limits the number of operating system threads that\ncan execute user-level Go code simultaneously. There is no limit to the number of threads\nthat can be blocked in system calls on behalf of Go code; those do not count against\nthe GOMAXPROCS limit. This package's GOMAXPROCS function queries and changes\nthe limit.\n\nThe GOTRACEBACK variable controls the amount of output generated when a Go\nprogram fails due to an unrecovered panic or an unexpected runtime condition.\nBy default, a failure prints a stack trace for the current goroutine,\neliding functions internal to the run-time system, and then exits with exit code 2.\nThe failure prints stack traces for all goroutines if there is no current goroutine\nor the failure is internal to the run-time.\nGOTRACEBACK=none omits the goroutine stack traces entirely.\nGOTRACEBACK=single (the default) behaves as described above.\nGOTRACEBACK=all adds stack traces for all user-created goroutines.\nGOTRACEBACK=system is like ``all'' but adds stack frames for run-time functions\nand shows goroutines created internally by the run-time.\nGOTRACEBACK=crash is like ``system'' but crashes in an operating system-specific\nmanner instead of exiting. For example, on Unix systems, the crash raises\nSIGABRT to trigger a core dump.\nFor historical reasons, the GOTRACEBACK settings 0, 1, and 2 are synonyms for\nnone, all, and system, respectively.\nThe runtime\/debug package's SetTraceback function allows increasing the\namount of output at run time, but it cannot reduce the amount below that\nspecified by the environment variable.\nSee https:\/\/golang.org\/pkg\/runtime\/debug\/#SetTraceback.\n\nThe GOARCH, GOOS, GOPATH, and GOROOT environment variables complete\nthe set of Go environment variables.

It is designed with the following goals:\n\n* Provide a simple convention for managing encryption & decryption keys. An\nencryption key is a PEM encoded NaCl box public key with title \"LOCKBOX PUBLIC\nENCRYPTION KEY\", stored with the file extension \".ekey\". A decryption key is a\nPEM encoded NaCl box private key with title \"LOCKBOX SECRET DECRYPTION KEY\",\nstored with the file extension \".dkey\".\n\n* Provide a simplified API for setup & encryption\/decryption. The Encryptor &\nDecryptor types are constructed with their corresponding key. The types have a\nsingle Encrypt\/Decrypt method that take a cleartext\/ciphertext byte slice\nparameter and returns a ciphertext\/cleartext byte slice.\n\n* Design the Encryptor so that it cannot decrypt the output of Encrypt once the\nfunction has returned.

A Pipeline has a series of\nPipelineStages, which will each perform some type of data processing, and\nthen send new data on to the next stage. Each PipelineStage consists of one\nor more DataProcessors, which are responsible for receiving, processing, and\nthen sending data on to the next stage of processing. DataProcessors each\nrun in their own goroutine, and therefore all data processing can be executing\nconcurrently.\n\nHere is a conceptual drawing of a fairly simple Pipeline:\n\n        +--Pipeline------------------------------------------------------------------------------------------+\n        |                                                                       PipelineStage 3              |\n        |                                                                      +---------------------------+ |\n        |  PipelineStage 1                 PipelineStage 2          +-JSON---> |  CSVWriter                | |\n        | +------------------+           +-----------------------+  |          +---------------------------+ |\n        | |  SQLReader       +-JSON----> | Custom DataProcessor  +--+                                        |\n        | +------------------+           +-----------------------+  |          +---------------------------+ |\n        |                                                           +-JSON---> |  SQLWriter                | |\n        |                                                                      +---------------------------+ |\n        +----------------------------------------------------------------------------------------------------+\n\nIn this example, we have a Pipeline consisting of 3 PipelineStages. The first stage has a DataProcessor that\nruns queries on a SQL database, the second is doing custom transformation\nwork on that data, and the third stage branches into 2 DataProcessors, one\nwriting the resulting data to a CSV file, and the other inserting into another\nSQL database.\n\nIn the example above, Stage 1 and Stage 3 are using built-in DataProcessors\n(see the \"processors\" package\/subdirectory). However, Stage 2 is using a custom\nimplementation of DataProcessor. By using a combination of built-in processors,\nand supporting the writing of any Go code to process data, Ratchet makes\nit possible to write very custom and fast data pipeline systems. See the\nDataProcessor documentation to learn more.\n\nSince each DataProcessor is running in it's own goroutine, SQLReader can continue pulling and sending\ndata while each subsequent stage is also processing data. Optimally-designed pipelines\nhave processors that can each run in an isolated fashion, processing data without having\nto worry about what's coming next down the pipeline.\n\nAll data payloads sent between DataProcessors are of type data.JSON ([]byte). This provides\na good balance of consistency and flexibility. See the \"data\" package for details\nand helper functions for dealing with data.JSON. Another good read for handling\nJSON data in Go is http:\/\/blog.golang.org\/json-and-go.\n\nNote that many of the concepts in Ratchet were taken from the Golang blog's post on\npipelines (http:\/\/blog.golang.org\/pipelines). While the details discussed in that\nblog post are largely abstracted away by Ratchet, it is still an interesting read and\nwill help explain the general concepts being applied.\n\nCreating and Running a Basic Pipeline\n\nThere are two ways to construct and run a Pipeline. The first is a basic, non-branching\nPipeline. For example:\n\n        +------------+   +-------------------+   +---------------+\n        | SQLReader  +---> CustomTransformer +---> SQLWriter     |\n        +------------+   +-------------------+   +---------------+\n\nThis is a 3-stage Pipeline that queries some SQL data in stage 1, does some custom data\ntransformation in stage 2, and then writes the resulting data to a SQL table in stage 3.\nThe code to create and run this basic Pipeline would look something like:\n\n        \/\/ First initalize the DataProcessors\n        read := processors.NewSQLReader(db1, \"SELECT * FROM source_table\")\n        transform := NewCustomTransformer() \/\/ (This would your own custom DataProcessor implementation)\n        write := processors.NewSQLWriter(db2, \"destination_table\")\n\n        \/\/ Then create a new Pipeline using them\n        pipeline := ratchet.NewPipeline(read, transform, write)\n\n        \/\/ Finally, run the Pipeline and wait for either an error or nil to be returned\n        err := <-pipeline.Run()\n\nCreating and Running a Branching Pipeline\n\nThe second way to construct a Pipeline is using a PipelineLayout. This method allows\nfor more complex Pipeline configurations that support branching between stages that\nare running multiple DataProcessors. Here is a (fairly complex) example:\n\n                                                                   +----------------------+\n                                                            +------> SQLReader (Dynamic)  +--+\n                                                            |      +----------------------+  |\n                                                            |                                |\n                         +---------------------------+      |      +----------------------+  |    +-----------+\n                   +-----> SQLReader (Dynamic Query) +------+   +--> Custom DataProcessor +-------> CSVWriter |\n    +-----------+  |     +---------------------------+      |   |  +----------------------+  |    +-----------+\n    | SQLReader +--+                                     +------+                            |\n    +-----------+  |     +---------------------------+   |  |      +----------------------+  |    +-----------+\n                   +-----> Custom DataProcessor      +------+------> Custom DataProcessor +--+  +-> SQLWriter |\n                         +---------------------------+   |         +----------------------+     | +-----------+\n                                                         |                                      |\n                                                         |         +----------------------+     |\n                                                         +---------> Passthrough          +-----+\n                                                                   +----------------------+\n\nThis Pipeline consists of 4 stages where each DataProcessor is choosing which DataProcessors\nin the subsequent stage should receive the data it sends. The SQLReader in stage 2, for example,\nis sending data to only 2 processors in the next stage, while the Custom DataProcessor in\nstage 2 is sending it's data to 3. The code for constructing and running a Pipeline like this\nwould look like:\n\n        \/\/ First, initialize all the DataProcessors that will be used in the Pipeline\n        query1 := processors.NewSQLReader(db1, \"SELECT * FROM source_table\")\n        query2 := processors.NewSQLReader(db1, sqlGenerator1) \/\/ sqlGenerator1 would be a function that generates the query at run-time.

The\nwidgets provided with this package are useful for data exploration and data\nentry.\n\nWidgets\n\nThe package implements the following widgets:\n\n  - TextView: A scrollable window that display multi-colored text. Text may also\n    be highlighted.\n  - Table: A scrollable display of tabular data. Table cells, rows, or columns\n    may also be highlighted.\n  - TreeView: A scrollable display for hierarchical data. Tree nodes can be\n    highlighted, collapsed, expanded, and more.\n  - List: A navigable text list with optional keyboard shortcuts.\n  - InputField: One-line input fields to enter text.\n  - DropDown: Drop-down selection fields.\n  - Checkbox: Selectable checkbox for boolean values.\n  - Button: Buttons which get activated when the user selects them.\n  - Form: Forms composed of input fields, drop down selections, checkboxes, and\n    buttons.\n  - Modal: A centered window with a text message and one or more buttons.\n  - Flex: A Flexbox based layout manager.\n  - Pages: A page based layout manager.\n\nThe package also provides Application which is used to poll the event queue and\ndraw widgets on screen.\n\nHello World\n\nThe following is a very basic example showing a box with the title \"Hello,\nworld!\":\n\n  package main\n\n  import (\n  \t\"github.com\/rivo\/tview\"\n  )\n\n  func main() {\n  \tbox := tview.NewBox().SetBorder(true).SetTitle(\"Hello, world!\")\n  \tif err := tview.NewApplication().SetRoot(box, true).Run(); err != nil {\n  \t\tpanic(err)\n  \t}\n  }\n\nFirst, we create a box primitive with a border and a title. Then we create an\napplication, set the box as its root primitive, and run the event loop. The\napplication exits when the application's Stop() function is called or when\nCtrl-C is pressed.\n\nIf we have a primitive which consumes key presses, we call the application's\nSetFocus() function to redirect all key presses to that primitive. Most\nprimitives then offer ways to install handlers that allow you to react to any\nactions performed on them.\n\nMore Demos\n\nYou will find more demos in the \"demos\" subdirectory. It also contains a\npresentation (written using tview) which gives an overview of the different\nwidgets and how they can be used.\n\nColors\n\nThroughout this package, colors are specified using the tcell.Color type.\nFunctions such as tcell.GetColor(), tcell.NewHexColor(), and tcell.NewRGBColor()\ncan be used to create colors from W3C color names or RGB values.\n\nAlmost all strings which are displayed can contain color tags. Color tags are\nW3C color names or six hexadecimal digits following a hash tag, wrapped in\nsquare brackets. Examples:\n\n  This is a [red]warning[white]!\n  The sky is [#8080ff]blue[#ffffff].\n\nA color tag changes the color of the characters following that color tag. This\napplies to almost everything from box titles, list text, form item labels, to\ntable cells. In a TextView, this functionality has to be switched on explicitly.\nSee the TextView documentation for more information.\n\nColor tags may contain not just the foreground (text) color but also the\nbackground color and additional flags. In fact, the full definition of a color\ntag is as follows:\n\n  [<foreground>:<background>:<flags>]\n\nEach of the three fields can be left blank and trailing fields can be omitted.\n(Empty square brackets \"[]\", however, are not considered color tags.) Colors\nthat are not specified will be left unchanged. A field with just a dash (\"-\")\nmeans \"reset to default\".\n\nYou can specify the following flags (some flags may not be supported by your\nterminal):\n\n  l: blink\n  b: bold\n  d: dim\n  r: reverse (switch foreground and background color)\n  u: underline\n\nExamples:\n\n  [yellow]Yellow text\n  [yellow:red]Yellow text on red background\n  [:red]Red background, text color unchanged\n  [yellow::u]Yellow text underlined\n  [::bl]Bold, blinking text\n  [::-]Colors unchanged, flags reset\n  [-]Reset foreground color\n  [-:-:-]Reset everything\n  [:]No effect\n  []Not a valid color tag, will print square brackets as they are\n\nIn the rare event that you want to display a string such as \"[red]\" or\n\"[#00ff1a]\" without applying its effect, you need to put an opening square\nbracket before the closing square bracket. Note that the text inside the\nbrackets will be matched less strictly than region or colors tags. I.e. any\ncharacter that may be used in color or region tags will be recognized. Examples:\n\n  [red[]      will be output as [red]\n  [\"123\"[]    will be output as [\"123\"]\n  [#6aff00[[] will be output as [#6aff00[]\n  [a#\"[[[]    will be output as [a#\"[[]\n  []          will be output as [] (see color tags above)\n  [[]         will be output as [[] (not an escaped tag)\n\nYou can use the Escape() function to insert brackets automatically where needed.\n\nStyles\n\nWhen primitives are instantiated, they are initialized with colors taken from\nthe global Styles variable. You may change this variable to adapt the look and\nfeel of the primitives to your preferred style.\n\nUnicode Support\n\nThis package supports unicode characters including wide characters.\n\nConcurrency\n\nMany functions in this package are not thread-safe. For many applications, this\nmay not be an issue: If your code makes changes in response to key events, it\nwill execute in the main goroutine and thus will not cause any race conditions.\n\nIf you access your primitives from other goroutines, however, you will need to\nsynchronize execution. The easiest way to do this is to call\nApplication.QueueUpdate() or Application.QueueUpdateDraw() (see the function\ndocumentation for details):\n\n  go func() {\n    app.QueueUpdateDraw(func() {\n      table.SetCellSimple(0, 0, \"Foo bar\")\n    })\n  }()\n\nOne exception to this is the io.Writer interface implemented by TextView. You\ncan safely write to a TextView from any goroutine. See the TextView\ndocumentation for details.\n\nType Hierarchy\n\nAll widgets listed above contain the Box type. All of Box's functions are\ntherefore available for all widgets, too.\n\nAll widgets also implement the Primitive interface. There is also the Focusable\ninterface which is used to override functions in subclassing types.\n\nThe tview package is based on https:\/\/github.com\/gdamore\/tcell.

{"text":"<commit_before>\/*\nPackage forget provides an in-memory cache for arbitrary, binary data.\n\nCaching\n\nThe cache identifies cached items by their key. Items to be stored are provided with their key, individually\nselected expiration time (TTL), and binary data. Storing an item with the same key, overrides the TTL and the\nprevious one. A cached item can be retrieved or deleted with its key. As a special use case, it is possible to\nstore only keys, where the useful information is whether a key exists, and whether it has expired. If a new item\ndoesn't fit in the free space, the least recently used item is evicted (LRU).\n\nKeyspaces\n\nKeyspaces, when used (see NewCacheSpaces()), allow the optimization for the LRU eviction mechanism. Items that\nare more expensive to produce but less frequently accessed than others, can be stored in different keyspaces.\nWhen eviction is required, the cache tries to evict enough items from the same keyspace as the one currently\nbeing filled. When using keyspaces, the same key can appear in different keyspaces pointing to different items.\n\nMemory\n\nThe cache allocates all the used memory on start. To support parallel access, it splits the allocated memory\ninto segments. There are typically as many segments as the maximum of NumCPU() and GOMAXPROCS(). The maximum\nsize of a stored item is the total cache size divided by the number of segments.\n\nThe segments are split into chunks. One cached item can span over multiple chunks, but the chunks cannot be\nshared between the items. This means that the cache is almost never fully utilized. The chunk size is an\ninitialization option, it typically should be a 'couple of times' smaller than the expected size of the 'bulk'\nof the cached items.\n\nThe cache counts the size of the item keys in the used space, but there is some lookup metadata that is not\ncounted: ~24 bytes for each chunk and ~120 bytes for each item.\n\nIO\n\nThe associated data of the keys can be accessed for read, seek and write through the standard Go interfaces. As\na shortcut, the data can be retrieved or set as a single byte slice, too. When using the IO interfaces, the item\ndata can be accessed concurrently, and reading from an item can be started before the write has finished. When\nthe reader reaches a point that was not yet filled by the writer, it blocks, and continues only when more data\nwas written, or returns with EOF once the write was finished.\n\nWhile writing an item, chunks are continuously assigned to the item from the free range of allocated memory. If\nthere are no free chunks, the cache evicts enough of the least recently used items. The cache doesn't evict\nthose items that are currently being read by an unclosed reader. Similarly, when deleting an item or overwriting\none, while it has active readers associated with it, the item is only marked for delete, but the active readers\ncan finish reading from it.\n\nMonitoring\n\nThe cache provides statistics about its internal state, including metrics like item count, effective and used\nsize, active readers and writers. When configured, it also provides change notifications. Depending on the\nconfigured notification mask, it can send events about: cache hit\/miss, evictions, allocation failures, etc.\n*\/\npackage forget\n<commit_msg>fix docs<commit_after>\/*\nPackage forget provides an in-memory cache for arbitrary, binary data.\n\nCaching\n\nThe cache identifies items by their keys.

{"text":"<commit_before>\/*\nPackage merkleTree is a generic Merkle Tree implementation, for provably publishing lots\nof data under one succinct tree root.\n\nInstall:\n\n   go get github.com\/keybase\/go-merkle-tree\n\nDesign:\n\nThis package outputs a MerkleTree with two types of nodes: interior index\nnodes, or iNodes, and exterior data nodes, of Leaf nodes. The inodes\nconsist of tables that map prefixes to child pointers.  The leafs map a full\nhash to a \"value\".\n\nThis is best demonstrated with a simple example. Let's say you are storing\nthe key-value pair (`0123456789abcdef`, {\"name\" : \"max\"}) in the Merkle tree.\nLet's say that the shape of the tree is to have 256 children per inode.\nThen this key-value pair might be stored under the path\n\n\tat root     node: 01 → aabbccdd\n\tat aabbccdd node: 23 → eeff5588\n\tat eeff5588 node: 34 → 99331122\n\tat 99331122 node: 0123456789abcdef → {\"name\" : \"max\" }\n\nMeaning at the root node, we take the first 256-bits of the needed\nkey to get a prefix `01`, and look that up in the node's pointer table\nto get a child pointer, which is `aabbccdd`.  This is a hash of an\niNode, which we can fetch from storage, verify it matches the hash,\nand then recursively apply the same algorithm to find the next\nstep in the path. The leaf node has a sparse table of long-hashes\n(which are the keys) that map to the values actually stored in the\ntree.\n\nImplementation:\n\nAll nodes are encoded with msgpack before being hashed or written to\nstore. See `types.go` for the exactly layout of the msgpack objects.\n\nUsage:\n\nTo construct a new Tree from scratch, you need to specify three parameters:\n\n\t- A Config, which specifies the shape of the Tree. That is,\n\t  how many children per interior Node, and how big leaves\n\t  can get before a new level of the tree is introduced.

Let's say you are storing\nthe key-value pair (`0123456789abcdef`, {\"name\" : \"max\"}) in the Merkle tree.\nLet's say that the shape of the tree is to have 256 children per inode.\nThen this key-value pair might be stored under the path\n\n\tat root     node: 01 → aabbccdd\n\tat aabbccdd node: 23 → eeff5588\n\tat eeff5588 node: 34 → 99331122\n\tat 99331122 node: 0123456789abcdef → {\"name\" : \"max\" }\n\nMeaning at the root node, we take the first 256-bits of the needed\nkey to get a prefix `01`, and look that up in the node's pointer table\nto get a child pointer, which is `aabbccdd`.  This is a hash of an\niNode, which we can fetch from storage, verify it matches the hash,\nand then recursively apply the same algorithm to find the next\nstep in the path. The leaf node has a sparse table of long-hashes\n(which are the keys) that map to the values actually stored in the\ntree.\n\nImplementation:\n\nAll nodes are encoded with msgpack before being hashed or written to\nstore. See `types.go` for the exactly layout of the msgpack objects.\n\nUsage:\n\nTo construct a new Tree from scratch, you need to specify three parameters:\n\n\t- A Config, which specifies the shape of the Tree. That is,\n\t  how many children per interior Node, and how big leaves\n\t  can get before a new level of the tree is introduced. Also,\n\t  the hash function to use for hashing nodes into pointers.\n\n\t- A StorageEngine, which determines how to load and store tree Nodes\n\t  from storage, and how to load and store the root hash of the Merkle tree.\n\n\t- An array of KeyValuePairs, the things actually stored in the Merkle tree.\n\n*\/\npackage merkleTree\n<|endoftext|>"}

{"text":"<commit_before>\/*\nPackage dbus implements bindings to the DBus message bus system, as well as the\ncorresponding encoding format.\n\nFor the message bus API, you first need to connect to a bus (usually the Session\nor System bus). Then, you can call methods with Call() and receive signals over\nthe channel returned by Signals(). Handling method calls is even easier; using\nExport(), you can arrange DBus message calls to be directly translated to method\ncalls on a Go value.\n\nDecoder and Encoder provide direct access to the DBus wire format. You usually\ndon't need to use them directly. While you may use them directly on the socket\nas they accept the standard io interfaces, it is not advised to do so as this\nwould generate many small reads \/ writes that could limit performance.\n\nRules for encoding are as follows:\n\n1. Any primitive Go type that has a direct equivalent in the wire format\nis directly converted. This includes all fixed size integers\nexcept for int8, as well as float64, bool and string.\n\n2. Slices and maps are converted to arrays and dicts, respectively.\n\n3. Most structs are converted to the expected DBus struct (all exported members\nare marshalled as a DBus struct). The exceptions are all types and structs\ndefined in this package that have a custom wire format. These are ObjectPath,\nSignature and Variant.

Then, you can call methods with Call() and receive signals over\nthe channel returned by Signals(). Handling method calls is even easier; using\nExport(), you can arrange DBus message calls to be directly translated to method\ncalls on a Go value.\n\nDecoder and Encoder provide direct access to the DBus wire format. You usually\ndon't need to use them directly. While you may use them directly on the socket\nas they accept the standard io interfaces, it is not advised to do so as this\nwould generate many small reads \/ writes that could limit performance.\n\nRules for encoding are as follows:\n\n1. Any primitive Go type that has a direct equivalent in the wire format\nis directly converted. This includes all fixed size integers\nexcept for int8, as well as float64, bool and string.\n\n2. Slices and maps are converted to arrays and dicts, respectively.\n\n3. Most structs are converted to the expected DBus struct (all exported members\nare marshalled as a DBus struct). The exceptions are all types and structs\ndefined in this package that have a custom wire format. These are ObjectPath,\nSignature and Variant. Also, fields whose tag contains dbus:\"-\" will be skipped.\n\n4. Trying to encode any other type (including int and uint!) will result\nin a panic. This applies to all functions that call (*Encoder).Encode somewhere.\n\nThe rules for decoding are mostly just the reverse of the encoding rules,\nexcept for the handling of variants. If a struct is wrapped in a variant,\nits decoded value will be a slice of interfaces which contain the struct\nfields in the correct order.\n\nBecause encoding and decoding of messages need special handling, they are also\nimplemented here.\n\n*\/\npackage dbus\n\n\/\/ BUG(guelfey): This package needs new reflection features that are only\n\/\/ availabe from the hg tip until Go 1.1 is released.\n<|endoftext|>"}

A client observes timestamps captured locally to\n\/\/ infer the state of the leader election. Thus the implementation is tolerant\n\/\/ to arbitrary clock skew, but is not tolerant to arbitrary clock skew rate.\n\/\/\n\/\/ However the level of tolerance to skew rate can be configured by setting\n\/\/ RenewDeadline and LeaseDuration appropriately. The tolerance expressed as a\n\/\/ maximum tolerated ratio of time passed on the fastest node to time passed on\n\/\/ the slowest node can be approximately achieved with a configuration that sets\n\/\/ the same ratio of LeaseDuration to RenewDeadline. For example if a user wanted\n\/\/ to tolerate some nodes progressing forward in time twice as fast as other nodes,\n\/\/ the user could set LeaseDuration to 60 seconds and RenewDeadline to 30 seconds.\n\/\/\n\/\/ While not required, some method of clock synchronization between nodes in the\n\/\/ cluster is highly recommended. It's important to keep in mind when configuring\n\/\/ this client that the tolerance to skew rate varies inversely to master\n\/\/ availability.\n\/\/\n\/\/ Larger clusters often have a more lenient SLA for API latency. This should be\n\/\/ taken into account when configuring the client. The rate of leader transitions\n\/\/ should be monitored and RetryPeriod and LeaseDuration should be increased\n\/\/ until the rate is stable and acceptably low.

This implementation does not guarantee that only one\n\/\/ client is acting as a leader (a.k.a. fencing).\n\/\/\n\/\/ A client observes timestamps captured locally to infer the state of the\n\/\/ leader election. Thus the implementation is tolerant to arbitrary clock\n\/\/ skew, but is not tolerant to arbitrary clock skew rate. Timestamp(renew time)\n\/\/ is not meaningful if it was collected on another machine. The implementation\n\/\/ of this client only acts on locally collected timestamps and cannot rely on\n\/\/ the accuracy of timestamp in the record for correctness.\n\/\/\n\/\/ However the level of tolerance to skew rate can be configured by setting\n\/\/ RenewDeadline and LeaseDuration appropriately. The tolerance expressed as a\n\/\/ maximum tolerated ratio of time passed on the fastest node to time passed on\n\/\/ the slowest node can be approximately achieved with a configuration that sets\n\/\/ the same ratio of LeaseDuration to RenewDeadline. For example if a user wanted\n\/\/ to tolerate some nodes progressing forward in time twice as fast as other nodes,\n\/\/ the user could set LeaseDuration to 60 seconds and RenewDeadline to 30 seconds.\n\/\/\n\/\/ While not required, some method of clock synchronization between nodes in the\n\/\/ cluster is highly recommended. It's important to keep in mind when configuring\n\/\/ this client that the tolerance to skew rate varies inversely to master\n\/\/ availability.\n\/\/\n\/\/ Larger clusters often have a more lenient SLA for API latency. This should be\n\/\/ taken into account when configuring the client. The rate of leader transitions\n\/\/ should be monitored and RetryPeriod and LeaseDuration should be increased\n\/\/ until the rate is stable and acceptably low. It's important to keep in mind\n\/\/ when configuring this client that the tolerance to API latency varies inversely\n\/\/ to master availability.\n\/\/\n\/\/ DISCLAIMER: this is an alpha API.

not result in\n\/\/ identify calls and just display the list of favorite names,\n\/\/ then when you `cd \/keybase\/private\/alice,bob` or `cp x.tar.gz\n\/\/ \/keybase\/private\/alice,bob,charlie` any

{"text":"<commit_before>\/\/ The `s3` plugin for SHIELD is intended to be a back-end storage\n\/\/ plugin, wrapping Amazon's Simple Storage Service (S3). It should\n\/\/ be compatible with other services which emulate the S3 API, offering\n\/\/ similar storage solutions for private cloud offerings (such as OpenStack\n\/\/ Swift). However, this plugin has only been tested with Amazon S3.\n\/\/\n\/\/ PLUGIN FEATURES\n\/\/\n\/\/ This plugin implements functionality suitable for use with the following\n\/\/ SHIELD Job components:\n\/\/\n\/\/  Target: no\n\/\/  Store:  yes\n\/\/\n\/\/ PLUGIN CONFIGURATION\n\/\/\n\/\/ The endpoint configuration passed to this plugin is used to determine\n\/\/ how to connect to S3, and where to place\/retrieve the data once connected.\n\/\/ your endpoint JSON should look something like this:\n\/\/\n\/\/    {\n\/\/        \"s3_host\":             \"s3.amazonaws.com\", # default\n\/\/        \"access_key_id\":       \"your-access-key-id\",\n\/\/        \"secret_access_key\":   \"your-secret-access-key\",\n\/\/        \"skip_ssl_validation\":  false,\n\/\/        \"bucket\":              \"bucket-name\",\n\/\/        \"prefix\":              \"\/path\/inside\/bucket\/to\/place\/backup\/data\",\n\/\/        \"signature_version\":   \"4\",  # should be 2 or 4. Defaults to 4\n\/\/        \"socks5_proxy\":        \"\"    # optionally defined SOCKS5 proxy to use for the s3 communications\n\/\/    }\n\/\/\n\/\/ `prefix` will default to the empty string, and backups will be placed in the\n\/\/ root of the bucket.\n\/\/\n\/\/ STORE DETAILS\n\/\/\n\/\/ When storing data, this plugin connects to the S3 service, and uploads the data\n\/\/ into the specified bucket, using a path\/filename with the following format:\n\/\/\n\/\/    <prefix>\/<YYYY>\/<MM>\/<DD>\/<HH-mm-SS>-<UUID>\n\/\/\n\/\/ Upon successful storage, the plugin then returns this filename to SHIELD to use\n\/\/ as the `store_key` when the data needs to be retrieved, or purged.\n\/\/\n\/\/ RETRIEVE DETAILS\n\/\/\n\/\/ When retrieving data, this plugin connects to the S3 service, and retrieves the data\n\/\/ located in the specified bucket, identified by the `store_key` provided by SHIELD.\n\/\/\n\/\/ PURGE DETAILS\n\/\/\n\/\/ When purging data, this plugin connects to the S3 service, and deletes the data\n\/\/ located in the specified bucket, identified by the `store_key` provided by SHIELD.\n\/\/\n\/\/ DEPENDENCIES\n\/\/\n\/\/ None.\n\/\/\npackage main\n\nimport

It should\n\/\/ be compatible with other services which emulate the S3 API, offering\n\/\/ similar storage solutions for private cloud offerings (such as OpenStack\n\/\/ Swift). However, this plugin has only been tested with Amazon S3.\n\/\/\n\/\/ PLUGIN FEATURES\n\/\/\n\/\/ This plugin implements functionality suitable for use with the following\n\/\/ SHIELD Job components:\n\/\/\n\/\/  Target: no\n\/\/  Store:  yes\n\/\/\n\/\/ PLUGIN CONFIGURATION\n\/\/\n\/\/ The endpoint configuration passed to this plugin is used to determine\n\/\/ how to connect to S3, and where to place\/retrieve the data once connected.\n\/\/ your endpoint JSON should look something like this:\n\/\/\n\/\/    {\n\/\/        \"s3_host\":             \"s3.amazonaws.com\", # default\n\/\/        \"access_key_id\":       \"your-access-key-id\",\n\/\/        \"secret_access_key\":   \"your-secret-access-key\",\n\/\/        \"skip_ssl_validation\":  false,\n\/\/        \"bucket\":              \"bucket-name\",\n\/\/        \"prefix\":              \"\/path\/inside\/bucket\/to\/place\/backup\/data\",\n\/\/        \"signature_version\":   \"4\",  # should be 2 or 4. Defaults to 4\n\/\/        \"socks5_proxy\":        \"\"    # optionally defined SOCKS5 proxy to use for the s3 communications\n\/\/    }\n\/\/\n\/\/ `prefix` will default to the empty string, and backups will be placed in the\n\/\/ root of the bucket.\n\/\/\n\/\/ STORE DETAILS\n\/\/\n\/\/ When storing data, this plugin connects to the S3 service, and uploads the data\n\/\/ into the specified bucket, using a path\/filename with the following format:\n\/\/\n\/\/    <prefix>\/<YYYY>\/<MM>\/<DD>\/<HH-mm-SS>-<UUID>\n\/\/\n\/\/ Upon successful storage, the plugin then returns this filename to SHIELD to use\n\/\/ as the `store_key` when the data needs to be retrieved, or purged.\n\/\/\n\/\/ RETRIEVE DETAILS\n\/\/\n\/\/ When retrieving data, this plugin connects to the S3 service, and retrieves the data\n\/\/ located in the specified bucket, identified by the `store_key` provided by SHIELD.\n\/\/\n\/\/ PURGE DETAILS\n\/\/\n\/\/ When purging data, this plugin connects to the S3 service, and deletes the data\n\/\/ located in the specified bucket, identified by the `store_key` provided by SHIELD.\n\/\/\n\/\/ DEPENDENCIES\n\/\/\n\/\/ None.\n\/\/\npackage main\n\nimport

Its goals are to help us fill out our test\n\/\/ pyramid by making it super easy to create unit-like tests directly from the snapshots, bug\n\/\/ reports, and other inputs provided by users who find regressions and\/or encounter other problems\n\/\/ in the field. Since we have no shortage of these reports, if we make it easy to create tests from\n\/\/ them, we will fill out our test pyramid quickly and hopefully reduce our rate of\n\/\/ regressions. This also means the tests produced this way need to scale well both in terms of\n\/\/ execution time\/parallelism as well as flakiness since we will quickly have a large number of\n\/\/ these tests.\n\/\/\n\/\/ The way this works is by isolating via dependency injection the key portions of the control plane\n\/\/ where the bulk of our business logic is implemented. The Fake utilities directly feed this\n\/\/ lightweight control plane its input as specified by the test code without passing the resources\n\/\/ all the way through a real kubernetes API server and\/or a real consul deployment. This is not\n\/\/ only significantly more efficient than spinning up real kubernetes and\/or consul deployments, but\n\/\/ it also lets us precisely control the order of events thereby a) removing the nondeterminism that\n\/\/ leads to flaky tests, and b) also allowing us to deliberately create\/recreate the sort of low\n\/\/ probability sequence of events that are often at the root of heisenbugs.\n\/\/\n\/\/ The key to being able to build tests this way is expressing our business logic as \"hermetically\n\/\/ sealed\" libraries, i.e. libraries with no\/few hardcoded dependencies. This doesn't have to be\n\/\/ done in a fancy\/elegant way, it is well worth practicing \"stupidly mechanical dependency\n\/\/ injection\" in order to quickly excise some business logic of its hardcoded dependencies and\n\/\/ enable this sort of testing.\n\/\/\n\/\/ See TestFakeHello, TestFakeHelloWithEnvoyConfig, and TestFakeHelloConsul for examples of how to\n\/\/ get started using this struct to write tests.\ntype Fake struct {\n\t\/\/ These are all read only fields.

Its goals are to help us fill out our test\n\/\/ pyramid by making it super easy to create unit-like tests directly from the snapshots, bug\n\/\/ reports, and other inputs provided by users who find regressions and\/or encounter other problems\n\/\/ in the field. Since we have no shortage of these reports, if we make it easy to create tests from\n\/\/ them, we will fill out our test pyramid quickly and hopefully reduce our rate of\n\/\/ regressions. This also means the tests produced this way need to scale well both in terms of\n\/\/ execution time\/parallelism as well as flakiness since we will quickly have a large number of\n\/\/ these tests.\n\/\/\n\/\/ The way this works is by isolating via dependency injection the key portions of the control plane\n\/\/ where the bulk of our business logic is implemented. The Fake utilities directly feed this\n\/\/ lightweight control plane its input as specified by the test code without passing the resources\n\/\/ all the way through a real kubernetes API server and\/or a real consul deployment. This is not\n\/\/ only significantly more efficient than spinning up real kubernetes and\/or consul deployments, but\n\/\/ it also lets us precisely control the order of events thereby a) removing the nondeterminism that\n\/\/ leads to flaky tests, and b) also allowing us to deliberately create\/recreate the sort of low\n\/\/ probability sequence of events that are often at the root of heisenbugs.\n\/\/\n\/\/ The key to being able to build tests this way is expressing our business logic as \"hermetically\n\/\/ sealed\" libraries, i.e. libraries with no\/few hardcoded dependencies. This doesn't have to be\n\/\/ done in a fancy\/elegant way, it is well worth practicing \"stupidly mechanical dependency\n\/\/ injection\" in order to quickly excise some business logic of its hardcoded dependencies and\n\/\/ enable this sort of testing.\n\/\/\n\/\/ See TestFakeHello, TestFakeHelloWithEnvoyConfig, and TestFakeHelloConsul for examples of how to\n\/\/ get started using this struct to write tests.\ntype Fake struct {\n\t\/\/ These are all read only fields.

Therefore, if we just\n\t\/\/ give up execution for a moment to let the other goroutines close\n\t\/\/ everything before calling server.Shutdown, we don't get punished by\n\t\/\/ having to wait 0.5s every time we try to shut down.\n\truntime.Gosched()\n\treturn resp[:n], server.Shutdown(ctx)\n}\n<commit_msg>Use a forceful shutdown instead of a graceful now in requesttesting.MakeRequest.<commit_after>\/\/ Copyright 2020 Google LLC\n\/\/\n\/\/ Licensed under the Apache License, Version 2.0 (the \"License\");\n\/\/ you may not use this file except in compliance with the License.\n\/\/ You may obtain a copy of the License at\n\/\/\n\/\/ \thttps:\/\/www.apache.org\/licenses\/LICENSE-2.0\n\/\/\n\/\/ Unless required by applicable law or agreed to in writing, software\n\/\/ distributed under the License is distributed on an \"AS IS\" BASIS,\n\/\/ WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied.\n\/\/ See the License for the specific language governing permissions and\n\/\/ limitations under the License.\n\n\/\/ Package requesttesting provides a harness and other test utilities for\n\/\/ verifying the behaviour of the net\/http package in Go's standard library.\npackage requesttesting\n\nimport (\n\t\"context\"\n\t\"errors\"\n\t\"io\"\n\t\"net\"\n\t\"net\/http\"\n\t\"sync\"\n)\n\n\/\/ AssertHandler is used to assert properties about the http.Request that it receives in using a callback function.\ntype AssertHandler struct {\n\tcallback func(*http.Request)\n}\n\nfunc (h *AssertHandler) ServeHTTP(w http.ResponseWriter, r *http.Request) {\n\th.callback(r)\n\tif _, err := io.WriteString(w, \"Hello world!\"); err != nil {\n\t\tpanic(err)\n\t}\n}\n\n\/\/ FakeListener creates a custom listener that avoids opening a socket in order\n\/\/ to establish communication between an HTTP client and server\ntype FakeListener struct {\n\tcloseOnce      sync.Once\n\tchannel        chan net.Conn\n\tserverEndpoint io.Closer\n\tclientEndpoint net.Conn\n}\n\n\/\/ NewFakeListener creates an instance of fakeListener.\nfunc NewFakeListener() *FakeListener {\n\ts2c, c2s := net.Pipe()\n\tc := make(chan net.Conn, 1)\n\tc <- s2c\n\treturn &FakeListener{\n\t\tchannel:        c,\n\t\tserverEndpoint: s2c,\n\t\tclientEndpoint: c2s,\n\t}\n}\n\n\/\/ Accept passes a network connection to the HTTP server to enable bidirectional communication with the client.\n\/\/ It will return an error if Accept is called after the listener was closed.\nfunc (l *FakeListener) Accept() (net.Conn, error) {\n\tch, ok := <-l.channel\n\tif !ok {\n\t\treturn nil, errors.New(\"Listener closed\")\n\t}\n\treturn ch, nil\n}\n\n\/\/ Close will close the two network connections and the listener.\nfunc (l *FakeListener) Close() error {\n\tl.closeOnce.Do(func() {\n\t\tclose(l.channel)\n\t})\n\terr := l.serverEndpoint.Close()\n\terr2 := l.clientEndpoint.Close()\n\tif err2 != nil {\n\t\treturn err2\n\t}\n\treturn err\n}\n\n\/\/ Addr returns the network address of the client endpoint.\nfunc (l *FakeListener) Addr() net.Addr {\n\treturn l.clientEndpoint.LocalAddr()\n}\n\n\/\/ SendRequest writes a request to the client endpoint connection.

It matches the URL of each incoming\n\/\/ request against a list of registered patterns and calls the handler for\n\/\/ the pattern that most closely matches the URL.\n\/\/\n\/\/ Patterns names are fixed, rooted paths, like \"\/favicon.ico\", or rooted\n\/\/ subtrees like \"\/images\/\" (note the trailing slash). Longer patterns take\n\/\/ precedence over shorter ones, so that if there are handlers registered for\n\/\/ both \"\/images\/\" and \"\/images\/thumbnails\/\", the latter handler will be called\n\/\/ for paths beginning \"\/images\/thumbnails\/\" and the former will receive\n\/\/ requests for any other paths in the \"\/images\/\" subtree.\n\/\/\n\/\/ Note that since a pattern ending in a slash names a rooted subtree, the\n\/\/ pattern \"\/\" matches all paths not matched by other registered patterns,\n\/\/ not just the URL with Path == \"\/\".\n\/\/\n\/\/ If a subtree has been registered and a request is received naming the subtree\n\/\/ root without its trailing slash, ServeMux redirects that request to\n\/\/ the subtree root (adding the trailing slash). This behavior can be overridden\n\/\/ with a separate registration for the path without the trailing slash. For\n\/\/ example, registering \"\/images\/\" causes ServeMux to redirect a request for\n\/\/ \"\/images\" to \"\/images\/\", unless \"\/images\" has been registered separately.\n\/\/\n\/\/ Patterns may optionally begin with a host name, restricting matches to URLs\n\/\/ on that host only.  Host-specific patterns take precedence over general\n\/\/ patterns, so that a handler might register for the two patterns \"\/codesearch\"\n\/\/ and \"codesearch.google.com\/\" without also taking over requests for\n\/\/ \"http:\/\/www.google.com\/\".\n\/\/\n\/\/ ServeMux also takes care of sanitizing the URL request path and the Host\n\/\/ header, stripping the port number and redirecting any request containing . or\n\/\/ .. elements or repeated slashes to an equivalent, cleaner URL.\n\/\/\n\/\/ Multiple handlers can be registered for a single pattern, as long as they\n\/\/ handle different HTTP methods.\ntype ServeMux struct {\n\tmux      *http.ServeMux\n\thandlers map[string]*registeredHandler\n\n\tdispatcher       Dispatcher\n\tinterceptors     []Interceptor\n\tmethodNotAllowed handlerConfig\n}\n\n\/\/ ServeHTTP dispatches the request to the handler whose method matches the\n\/\/ incoming request and whose pattern most closely matches the request URL.\n\/\/\n\/\/  For each incoming request:\n\/\/  - [Before Phase] Interceptor.Before methods are called for every installed\n\/\/    interceptor, until an interceptor writes to a ResponseWriter (including\n\/\/    errors) or panics,\n\/\/  - the handler is called after a [Before Phase] if no writes or panics occured,\n\/\/  - the handler triggers the [Commit Phase] by writing to the ResponseWriter,\n\/\/  - [Commit Phase] Interceptor.Commit methods run for every interceptor whose\n\/\/    Before method was called,\n\/\/  - [Dispatcher Phase] after the [Commit Phase], the Dispatcher's appropriate\n\/\/    write method is called; the Dispatcher is responsible for determining whether\n\/\/    the response is indeed safe and writing it,\n\/\/  - if the handler attempts to write more than once, it is treated as an\n\/\/    unrecoverable error; the request processing ends abrubptly with a panic and\n\/\/    nothing else happens (note: this will change as soon as [After Phase] is\n\/\/    introduced)\n\/\/\n\/\/ Interceptors should NOT rely on the order they're run.\nfunc (m *ServeMux) ServeHTTP(w http.ResponseWriter, r *http.Request) {\n\tm.mux.ServeHTTP(w, r)\n}\n\n\/\/ Handle registers a handler for the given pattern and method.

It matches the URL of each incoming\n\/\/ request against a list of registered patterns and calls the handler for\n\/\/ the pattern that most closely matches the URL.\n\/\/\n\/\/ Patterns names are fixed, rooted paths, like \"\/favicon.ico\", or rooted\n\/\/ subtrees like \"\/images\/\" (note the trailing slash). Longer patterns take\n\/\/ precedence over shorter ones, so that if there are handlers registered for\n\/\/ both \"\/images\/\" and \"\/images\/thumbnails\/\", the latter handler will be called\n\/\/ for paths beginning \"\/images\/thumbnails\/\" and the former will receive\n\/\/ requests for any other paths in the \"\/images\/\" subtree.\n\/\/\n\/\/ Note that since a pattern ending in a slash names a rooted subtree, the\n\/\/ pattern \"\/\" matches all paths not matched by other registered patterns,\n\/\/ not just the URL with Path == \"\/\".\n\/\/\n\/\/ If a subtree has been registered and a request is received naming the subtree\n\/\/ root without its trailing slash, ServeMux redirects that request to\n\/\/ the subtree root (adding the trailing slash). This behavior can be overridden\n\/\/ with a separate registration for the path without the trailing slash. For\n\/\/ example, registering \"\/images\/\" causes ServeMux to redirect a request for\n\/\/ \"\/images\" to \"\/images\/\", unless \"\/images\" has been registered separately.\n\/\/\n\/\/ Patterns may optionally begin with a host name, restricting matches to URLs\n\/\/ on that host only.  Host-specific patterns take precedence over general\n\/\/ patterns, so that a handler might register for the two patterns \"\/codesearch\"\n\/\/ and \"codesearch.google.com\/\" without also taking over requests for\n\/\/ \"http:\/\/www.google.com\/\".\n\/\/\n\/\/ ServeMux also takes care of sanitizing the URL request path and the Host\n\/\/ header, stripping the port number and redirecting any request containing . or\n\/\/ .. elements or repeated slashes to an equivalent, cleaner URL.\n\/\/\n\/\/ Multiple handlers can be registered for a single pattern, as long as they\n\/\/ handle different HTTP methods.\ntype ServeMux struct {\n\tmux      *http.ServeMux\n\thandlers map[string]*registeredHandler\n\n\tdispatcher       Dispatcher\n\tinterceptors     []Interceptor\n\tmethodNotAllowed handlerConfig\n}\n\n\/\/ ServeHTTP dispatches the request to the handler whose method matches the\n\/\/ incoming request and whose pattern most closely matches the request URL.\n\/\/\n\/\/  For each incoming request:\n\/\/  - [Before Phase] Interceptor.Before methods are called for every installed\n\/\/    interceptor, until an interceptor writes to a ResponseWriter (including\n\/\/    errors) or panics,\n\/\/  - the handler is called after a [Before Phase] if no writes or panics occured,\n\/\/  - the handler triggers the [Commit Phase] by writing to the ResponseWriter,\n\/\/  - [Commit Phase] Interceptor.Commit methods run for every interceptor whose\n\/\/    Before method was called,\n\/\/  - [Dispatcher Phase] after the [Commit Phase], the Dispatcher's appropriate\n\/\/    write method is called; the Dispatcher is responsible for determining whether\n\/\/    the response is indeed safe and writing it,\n\/\/  - if the handler attempts to write more than once, it is treated as an\n\/\/    unrecoverable error; the request processing ends abrubptly with a panic and\n\/\/    nothing else happens (note: this will change as soon as [After Phase] is\n\/\/    introduced)\n\/\/\n\/\/ Interceptors should NOT rely on the order they're run.\nfunc (m *ServeMux) ServeHTTP(w http.ResponseWriter, r *http.Request) {\n\tm.mux.ServeHTTP(w, r)\n}\n\n\/\/ Handle registers a handler for the given pattern and method.

Functions with multiple\nreturn values are mapped to functions returning a struct.\nNot all Go types can be mapped to C types in a useful way.\n\nCgo transforms the input file into four output files: two Go source\nfiles, a C file for 6c (or 8c or 5c), and a C file for gcc.\n\nThe standard package makefile rules in Make.pkg automate the\nprocess of using cgo.  See $GOROOT\/misc\/cgo\/stdio and\n$GOROOT\/misc\/cgo\/gmp for examples.\n\nCgo does not yet work with gccgo.\n\nSee \"C? Go? Cgo!\" for an introduction to using cgo:\nhttp:\/\/blog.golang.org\/2011\/03\/c-go-cgo.html\n*\/\npackage documentation\n<|endoftext|>"}

At a high level, this package provides\nthe facilities to perform this task with a focus on security and also allows\nrecovery through the use of hierarchical deterministic keys (BIP0032) generated\nfrom a caller provided seed.  The specific structure used is as described in\nBIP0044.  This setup means as long as the user writes the seed down (even better\nis to use a mnemonic for the seed), all their addresses and private keys can be\nregenerated from the seed.\n\nThere are two master keys which are protected by two independent passphrases.\nOne is intended for public facing data, while the other is intended for private\ndata.  The public password can be hardcoded for callers who don't want the\nadditional public data protection or the same password can be used if a single\npassword is desired.  These choices provide a usability versus security\ntradeoff.  However, keep in mind that extended hd keys, as called out in BIP0032\nneed to be handled more carefully than normal EC public keys because they can be\nused to generate all future addresses.  While this is part of what makes them\nattractive, it also means an attacker getting access to your extended public key\nfor an account will allow them to know all addresses you will use and hence\nreduces privacy.  For this reason, it is highly recommended that you do not hard\ncode a password which allows any attacker who gets a copy of your address\nmanager database to access your effectively plain text extended public keys.\n\nEach master key in turn protects the three real encryption keys (called crypto\nkeys) for public, private, and script data.  Some examples include payment\naddresses, extended hd keys, and scripts associated with pay-to-script-hash\naddresses.  This scheme makes changing passphrases more efficient since only the\ncrypto keys need to be re-encrypted versus every single piece of information\n(which is what is needed for *rekeying*).  This results in a fully encrypted\ndatabase where access to it does not compromise address, key, or script privacy.\nThis differs from the handling by other wallets at the time of this writing in\nthat they divulge your addresses, and worse, some even expose the chain code\nwhich can be used by the attacker to know all future addresses that will be\nused.\n\nThe address manager is also hardened against memory scrapers.  This is\naccomplished by typically having the address manager locked meaning no private\nkeys or scripts are in memory.  Unlocking the address manager causes the crypto\nprivate and script keys to be decrypted and loaded in memory which in turn are\nused to decrypt private keys and scripts on demand.  Relocking the address\nmanager actively zeros all private material from memory.  In addition, temp\nprivate key material used internally is zeroed as soon as it's used.\n\nLocking and Unlocking\n\nAs previously mentioned, this package provide facilities for locking and\nunlocking the address manager to protect access to private material and remove\nit from memory when locked.  The Lock, Unlock, and IsLocked functions are used\nfor this purpose.\n\nCreating a New Address Manager\n\nA new address manager is created via the Create function.  This function accepts\nthe path to a database file to create, passphrases, network, and perhaps most\nimportantly, a cryptographically random seed which is used to generate the\nmaster node of the hierarchical deterministic keychain which allows all\naddresses and private keys to be recovered with only the seed.  The GenerateSeed\nfunction in the hdkeychain package can be used as a convenient way to create a\nrandom seed for use with this function.  The address manager is locked\nimmediately upon being created.\n\nOpening an Existing Address Manager\n\nAn existing address manager is opened via the Open function.  This function\naccepts the path to the existing database file, the public passphrase, and\nnetwork.  The address manager is opened locked as expected since the open\nfunction does not take the private passphrase to unlock it.\n\nClosing the Address Manager\n\nThe Close method should be called on the address manager when the caller is done\nwith it.  While it is not required, it is recommended because it sanely shuts\ndown the database and ensures all private and public key material is purged from\nmemory.\n\nManaged Addresses\n\nEach address returned by the address manager satisifies the ManagedAddress\ninterface as well as either the ManagedPubKeyAddress or ManagedScriptAddress\ninterfaces.  These interfaces provide the means to obtain relevant information\nabout the addresses such as their private keys and scripts.\n\nChained Addresses\n\nMost callers will make use of the chained addresses for normal operations.\nInternal addresses are intended for internal wallet uses such as change outputs,\nwhile external addresses are intended for uses such payment addresses that are\nshared.  The NextInternalAddresses and NextExternalAddresses functions provide\nthe means to acquire one or more of the next addresses that have not already\nbeen provided.  In addition, the LastInternalAddress and LastExternalAddress\nfunctions can be used to get the most recently provided internal and external\naddress, respectively.\n\nRequesting Existing Addresses\n\nIn addition to generating new addresses, access to old addresses is often\nrequired.  Most notably, to sign transactions in order to redeem them.  The\nAddress function provides this capability and returns a ManagedAddress.\n\nImporting Addresses\n\nWhile the recommended approach is to use the chained addresses discussed above\nbecause they can be deterministically regenerated to avoid losing funds as long\nas the user has the master seed, there are many addresses that already exist,\nand as a result, this package provides the ability to import existing private\nkeys in Wallet Import Format (WIF) and hence the associated public key and\naddress.\n\nImporting Scripts\n\nIn order to support pay-to-script-hash transactions, the script must be securely\nstored as it is needed to redeem the transaction.  This can be useful for a\nvariety of scenarios, however the most common use is currently multi-signature\ntransactions.\n\nSyncing\n\nThe address manager also supports storing and retrieving a block hash and height\nwhich the manager is known to have all addresses synced through.  The manager\nitself does not have any notion of which addresses are synced or not.  It only\nprovides the storage as a convenience for the caller.\n\nNetwork\n\nThe address manager must be associated with a given network in order to provide\nappropriate addresses and reject imported addresses and scripts which don't\napply to the associated network.\n\nErrors\n\nAll errors returned from this package are of type waddrmgr.ManagerError.  This\nallows the caller to programmatically ascertain the specific reasons for failure\nby examining the ErrorCode field of the type asserted ManagerError.  For certain\nerror codes, as documented the specific error codes, the underlying error will\nbe contained in the Err field.\n\nBitcoin Improvement Proposals\n\nThis package includes concepts outlined by the following BIPs:\n\n\t\tBIP0032 (https:\/\/github.com\/bitcoin\/bips\/blob\/master\/bip-0032.mediawiki)\n\t\tBIP0043 (https:\/\/github.com\/bitcoin\/bips\/blob\/master\/bip-0043.mediawiki)\n\t\tBIP0044 (https:\/\/github.com\/bitcoin\/bips\/blob\/master\/bip-0044.mediawiki)\n*\/\npackage waddrmgr\n<commit_msg>waddrmgr: Update documentation for walletdb.<commit_after>\/*\n * Copyright (c) 2014 Conformal Systems LLC <info@conformal.com>\n *\n * Permission to use, copy, modify, and distribute this software for any\n * purpose with or without fee is hereby granted, provided that the above\n * copyright notice and this permission notice appear in all copies.\n *\n * THE SOFTWARE IS PROVIDED \"AS IS\" AND THE AUTHOR DISCLAIMS ALL WARRANTIES\n * WITH REGARD TO THIS SOFTWARE INCLUDING ALL IMPLIED WARRANTIES OF\n * MERCHANTABILITY AND FITNESS.

At a high level, this package provides\nthe facilities to perform this task with a focus on security and also allows\nrecovery through the use of hierarchical deterministic keys (BIP0032) generated\nfrom a caller provided seed.  The specific structure used is as described in\nBIP0044.  This setup means as long as the user writes the seed down (even better\nis to use a mnemonic for the seed), all their addresses and private keys can be\nregenerated from the seed.\n\nThere are two master keys which are protected by two independent passphrases.\nOne is intended for public facing data, while the other is intended for private\ndata.  The public password can be hardcoded for callers who don't want the\nadditional public data protection or the same password can be used if a single\npassword is desired.  These choices provide a usability versus security\ntradeoff.  However, keep in mind that extended hd keys, as called out in BIP0032\nneed to be handled more carefully than normal EC public keys because they can be\nused to generate all future addresses.  While this is part of what makes them\nattractive, it also means an attacker getting access to your extended public key\nfor an account will allow them to know all derived addresses you will use and\nhence reduces privacy.  For this reason, it is highly recommended that you do\nnot hard code a password which allows any attacker who gets a copy of your\naddress manager database to access your effectively plain text extended public\nkeys.\n\nEach master key in turn protects the three real encryption keys (called crypto\nkeys) for public, private, and script data.  Some examples include payment\naddresses, extended hd keys, and scripts associated with pay-to-script-hash\naddresses.  This scheme makes changing passphrases more efficient since only the\ncrypto keys need to be re-encrypted versus every single piece of information\n(which is what is needed for *rekeying*).

If that second value is present and evaluates to\nnon-nil, execution terminates and the error is returned to the caller of\nExecute.\n\nVariables\n\nA pipeline inside an action may initialize a variable to capture the result.\nThe initialization has syntax\n\n\t$variable := pipeline\n\nwhere $variable is the name of the variable. An action that declares a\nvariable produces no output.\n\nIf a \"range\" action initializes a variable, the variable is set to the\nsuccessive elements of the iteration.  Also, a \"range\" may declare two\nvariables, separated by a comma:\n\n\t$index, $element := pipeline\n\nin which case $index and $element are set to the successive values of the\narray\/slice index or map key and element, respectively.  Note that if there is\nonly one variable, it is assigned the element; this is opposite to the\nconvention in Go range clauses.\n\nA variable's scope extends to the \"end\" action of the control structure (\"if\",\n\"with\", or \"range\") in which it is declared, or to the end of the template if\nthere is no such control structure.  A template invocation does not inherit\nvariables from the point of its invocation.\n\nWhen execution begins, $ is set to the data argument passed to Execute, that is,\nto the starting value of dot.\n\nExamples\n\nHere are some example one-line templates demonstrating pipelines and variables.\nAll produce the quoted word \"output\":\n\n\t{{\"\\\"output\\\"\"}}\n\t\tA string constant.\n\t{{`\"output\"`}}\n\t\tA raw string constant.\n\t{{printf \"%q\" \"output\"}}\n\t\tA function call.\n\t{{\"output\" | printf \"%q\"}}\n\t\tA function call whose final argument comes from the previous\n\t\tcommand.\n\t{{\"put\" | printf \"%s%s\" \"out\" | printf \"%q\"}}\n\t\tA more elaborate call.\n\t{{\"output\" | printf \"%s\" | printf \"%q\"}}\n\t\tA longer chain.\n\t{{with \"output\"}}{{printf \"%q\" .}}{{end}}\n\t\tA with action using dot.\n\t{{with $x := \"output\" | printf \"%q\"}}{{$x}}{{end}}\n\t\tA with action that creates and uses a variable.\n\t{{with $x := \"output\"}}{{printf \"%q\" $x}}{{end}}\n\t\tA with action that uses the variable in another action.\n\t{{with $x := \"output\"}}{{$x | printf \"%q\"}}{{end}}\n\t\tThe same, but pipelined.\n\nFunctions\n\nDuring execution functions are found in two function maps: first in the\ntemplate, then in the global function map. By default, no functions are defined\nin the template but the Funcs methods can be used to add them.\n\nPredefined global functions are named as follows.\n\n\tand\n\t\tReturns the boolean AND of its arguments by returning the\n\t\tfirst empty argument or the last argument, that is,\n\t\t\"and x y\" behaves as \"if x then y else x\".

Thus \"index x 1 2 3\" is, in Go syntax,\n\t\tx[1][2][3]. Each indexed item must be a map, slice, or array.\n\tjs\n\t\tReturns the escaped JavaScript equivalent of the textual\n\t\trepresentation of its arguments.\n\tlen\n\t\tReturns the integer length of its argument.\n\tnot\n\t\tReturns the boolean negation of its single argument.\n\tor\n\t\tReturns the boolean OR of its arguments by returning the\n\t\tfirst non-empty argument or the last argument, that is,\n\t\t\"or x y\" behaves as \"if x then x else y\". All the\n\t\targuments are evaluated.\n\tprint\n\t\tAn alias for fmt.Sprint\n\tprintf\n\t\tAn alias for fmt.Sprintf\n\tprintln\n\t\tAn alias for fmt.Sprintln\n\turlquery\n\t\tReturns the escaped value of the textual representation of\n\t\tits arguments in a form suitable for embedding in a URL query.\n\nThe boolean functions take any zero value to be false and a non-zero value to\nbe true.\n\nAssociated templates\n\nEach template is named by a string specified when it is created. Also, each\ntemplate is associated with zero or more other templates that it may invoke by\nname; such associations are transitive and form a name space of templates.\n\nA template may use a template invocation to instantiate another associated\ntemplate; see the explanation of the \"template\" action above. The name must be\nthat of a template associated with the template that contains the invocation.\n\nNested template definitions\n\nWhen parsing a template, another template may be defined and associated with the\ntemplate being parsed. Template definitions must appear at the top level of the\ntemplate, much like global variables in a Go program.\n\nThe syntax of such definitions is to surround each template declaration with a\n\"define\" and \"end\" action.\n\nThe define action names the template being created by providing a string\nconstant. Here is a simple example:\n\n\t`{{define \"T1\"}}ONE{{end}}\n\t{{define \"T2\"}}TWO{{end}}\n\t{{define \"T3\"}}{{template \"T1\"}} {{template \"T2\"}}{{end}}\n\t{{template \"T3\"}}`\n\nThis defines two templates, T1 and T2, and a third T3 that invokes the other two\nwhen it is executed. Finally it invokes T3. If executed this template will\nproduce the text\n\n\tONE TWO\n\nBy construction, a template may reside in only one association. If it's\nnecessary to have a template addressable from multiple associations, the\ntemplate definition must be parsed multiple times to create distinct *Template\nvalues.\n\nParse may be called multiple times to assemble the various associated templates;\nsee the ParseFiles and ParseGlob functions and methods for simple ways to parse\nrelated templates stored in files.\n\nA template may be executed directly or through ExecuteTemplate, which executes\nan associated template identified by name. To invoke our example above, we\nmight write,\n\n\terr := tmpl.Execute(os.Stdout, \"no data needed\")\n\tif err != nil {\n\t\tlog.Fatalf(\"execution failed: %s\", err)\n\t}\n\nor to invoke a particular template explicitly by name,\n\n\terr := tmpl.ExecuteTemplate(os.Stdout, \"T2\", \"no data needed\")\n\tif err != nil {\n\t\tlog.Fatalf(\"execution failed: %s\", err)\n\t}\n\n*\/\npackage template\n<commit_msg>template: refer HTML users to html\/template<commit_after>\/\/ Copyright 2011 The Go Authors.

image file, partitions it and formats the filesystems.\n\nYaml syntax:\n - action: image-partition\n   imagename: image_name\n   imagesize: size\n   partitiontype: gpt\n   gpt_gap: offset\n   partitions:\n     <list of partitions>\n   mountpoints:\n     <list of mount points>\n\nMandatory properties:\n\n- imagename -- the name of the image file.\n\n- imagesize -- generated image size in human-readable form, examples: 100MB, 1GB, etc.\n\n- partitiontype -- partition table type. Currently only 'gpt' and 'msdos'\npartition tables are supported.\n\n- gpt_gap -- shifting GPT allow to use this gap for bootloaders, for example if\nU-Boot intersects with original GPT placement.\nOnly works if parted supports an extra argument to mklabel to specify the gpt offset.\n\n- partitions -- list of partitions, at least one partition is needed.\nPartition properties are described below.\n\n- mountpoints -- list of mount points for partitions.\nProperties for mount points are described below.\n\nYaml syntax for partitions:\n\n   partitions:\n     - name: label\n\t   name: partition name\n\t   fs: filesystem\n\t   start: offset\n\t   end: offset\n\t   flags: list of flags\n\nMandatory properties:\n\n- name -- is used for referencing named partition for mount points\nconfiguration (below) and label the filesystem located on this partition.\n\n- fs -- filesystem type used for formatting.\n\n'none' fs type should be used for partition without filesystem.\n\n- start -- offset from beginning of the disk there the partition starts.\n\n- end -- offset from beginning of the disk there the partition ends.\n\nFor 'start' and 'end' properties offset can be written in human readable\nform -- '32MB', '1GB' or as disk percentage -- '100%'.\n\nOptional properties:\n\n- flags -- list of additional flags for partition compatible with parted(8)\n'set' command.\n\nYaml syntax for mount points:\n\n   mountpoints:\n     - mountpoint: path\n\t   partition: partition label\n\t   options: list of options\n\nMandatory properties:\n\n- partition -- partition name for mounting.\n\n- mountpoint -- path in the target root filesystem where the named partition\nshould be mounted.\n\nOptional properties:\n\n- options -- list of options to be added to appropriate entry in fstab file.\n\nLayout example for Raspberry PI 3:\n\n - action: image-partition\n   imagename: \"debian-rpi3.img\"\n   imagesize: 1GB\n   partitiontype: msdos\n   mountpoints:\n     - mountpoint: \/\n       partition: root\n     - mountpoint: \/boot\/firmware\n       partition: firmware\n       options: [ x-systemd.automount ]\n   partitions:\n     - name: firmware\n       fs: vfat\n       start: 0%\n       end: 64MB\n     - name: root\n       fs: ext4\n       start: 64MB\n       end: 100%\n       flags: [ boot ]\n*\/\npackage actions\n\nimport

On BSD\n\/\/ systems, doing this in a race-free manner is trivial, via O_EXLOCK in\n\/\/ an open(2) call, but this is generally unavailable on Unix-like\n\/\/ systems due to Linux's lack of support for this option.\n\/\/\n\/\/ Consider several processes' hypothetical sequences of open, lock,\n\/\/ close (thus implicitly removing the kernel advisory lock), and\n\/\/ unlink.\n\/\/\n\/\/\tA       B       C\n\/\/\topen\n\/\/\t        open\n\/\/\tlock\n\/\/\tclose\n\/\/\t        lock\n\/\/\tunlink\n\/\/\t                open\n\/\/\t                lock\n\/\/\n\/\/ Now B thinks it's got a lock, but its lock file has been removed.  C\n\/\/ has opened the same lock file name, thus creating a new file, and\n\/\/ locked it.  So now B and C both think they've got the lock.  Game\n\/\/ over.\n\/\/\n\/\/ You might attempt re-arranging the close and unlink calls, but the\n\/\/ problem remains.  In general, if B opens the same file as A, and B\n\/\/ locks after A closes, then B can have a lock on a dangling file\n\/\/ descriptor.\n\/\/\n\/\/ The general problem is that the close and unlink steps are not\n\/\/ atomic.\n\/\/\n\/\/ Removable Lock Files - A Solution\n\/\/\n\/\/ One solution is to guard the two halves of the removable lock file\n\/\/ operations, open and lock, and close and unlink, with another lock\n\/\/ file that is itself not removed.  This is the approach that this\n\/\/ package takes with LockRm.  Using this approach, removable lock files\n\/\/ may be implemented with in a race-free manner.\npackage lockfile\n\n\/\/ Close calls' errors are not handled explicitly.  The error conditions\n\/\/ all end up with the file descriptor being closed anyway, so there is\n\/\/ nothing special to handle.\n\nimport (\n\t\"os\"\n\n\t\"golang.org\/x\/sys\/unix\"\n)\n\nconst mode = 0666\n\n\/\/ Obtain a LockContext by calling Lock or LockNb.

{"text":"<commit_before>\/\/ Package platforms provides a toolkit for normalizing, matching and\n\/\/ specifying container platforms.\n\/\/\n\/\/ Centered around OCI platform specifications, we define a string-based\n\/\/ specifier syntax that can be used for user input. With a specifier, users\n\/\/ only need to specify the parts of the platform that are relevant to their\n\/\/ context, providing an operating system or architecture or both.\n\/\/\n\/\/ How do I use this package?\n\/\/\n\/\/ The vast majority of use cases should simply use the match function with\n\/\/ user input. The first step is to parse a specifier into a matcher:\n\/\/\n\/\/   m, err := Parse(\"linux\")\n\/\/   if err != nil { ... }\n\/\/\n\/\/ Once you have a matcher, use it to match against the platform declared by a\n\/\/ component, typically from an image or runtime. Since extracting an images\n\/\/ platform is a little more involved, we'll use an example against the\n\/\/ platform default:\n\/\/\n\/\/   if ok := m.Match(Default()); !ok { \/* doesn't match *\/ }\n\/\/\n\/\/ This can be composed in loops for resolving runtimes or used as a filter for\n\/\/ fetch and select images.\n\/\/\n\/\/ More details of the specifier syntax and platform spec follow.\n\/\/\n\/\/ Declaring Platform Support\n\/\/\n\/\/ Components that have strict platform requirements should use the OCI\n\/\/ platform specification to declare their support. Typically, this will be\n\/\/ images and runtimes that should make these declaring which platform they\n\/\/ support specifically. This looks roughly as follows:\n\/\/\n\/\/   type Platform struct {\n\/\/\t   Architecture string\n\/\/\t   OS           string\n\/\/\t   Variant      string\n\/\/   }\n\/\/\n\/\/ Most images and runtimes should at least set Architecture and OS, according\n\/\/ to their GOARCH and GOOS values, respectively (follow the OCI image\n\/\/ specification when in doubt). ARM should set variant under certain\n\/\/ discussions, which are outlined below.\n\/\/\n\/\/ Platform Specifiers\n\/\/\n\/\/ While the OCI platform specifications provide a tool for components to\n\/\/ specify structured information, user input typically doesn't need the full\n\/\/ context and much can be inferred. To solve this problem, we introduced\n\/\/ \"specifiers\". A specifier has the format `<os|arch>[\/<arch>[\/<variant>]]`.\n\/\/ The user can provide either the operating system or the architecture or both.\n\/\/\n\/\/ An example of a common specifier is `linux\/amd64`. If the host has a default\n\/\/ of runtime that matches this, the user can simply provide the component that\n\/\/ matters. For example, if a image provides amd64 and arm64 support, the\n\/\/ operating system, `linux` can be inferred, so they only have to provide\n\/\/ `arm64` or `amd64`. Similar behavior is implemented for operating systems,\n\/\/ where the architecture may be known but a runtime may support images from\n\/\/ different operating systems.\n\/\/\n\/\/ Normalization\n\/\/\n\/\/ Because not all users are familiar with the way the Go runtime represents\n\/\/ platforms, several normalizations have been provided to make this package\n\/\/ easier to user.\n\/\/\n\/\/ The following are performed for architectures:\n\/\/\n\/\/   Value    Normalized\n\/\/   aarch64  arm64\n\/\/   armhf    arm\n\/\/   armel    arm\/v6\n\/\/   i386     386\n\/\/   x86_64   amd64\n\/\/   x86-64   amd64\n\/\/\n\/\/ We also normalize the operating system `macos` to `darwin`.\n\/\/\n\/\/ ARM Support\n\/\/\n\/\/ To qualify ARM architecture, the Variant field is used to qualify the arm\n\/\/ version. The most common arm version, v7, is represented without the variant\n\/\/ unless it is explicitly provided. This is treated as equivalent to armhf. A\n\/\/ previous architecture, armel, will be normalized to arm\/v6.\n\/\/\n\/\/ While these normalizations are provided, their support on arm platforms has\n\/\/ not yet been fully implemented and tested.\npackage platforms\n\nimport (\n\t\"regexp\"\n\t\"runtime\"\n\t\"strings\"\n\n\t\"github.com\/containerd\/containerd\/errdefs\"\n\tspecs \"github.com\/opencontainers\/image-spec\/specs-go\/v1\"\n\t\"github.com\/pkg\/errors\"\n)\n\nvar (\n\tspecifierRe = regexp.MustCompile(`^[A-Za-z0-9_-]+$`)\n)\n\n\/\/ Matcher matches platforms specifications, provided by an image or runtime.\ntype Matcher interface {\n\tSpec() specs.Platform\n\tMatch(platform specs.Platform) bool\n}\n\ntype matcher struct {\n\tspecs.Platform\n}\n\nfunc (m *matcher) Spec() specs.Platform {\n\treturn m.Platform\n}\n\nfunc (m *matcher) Match(platform specs.Platform) bool {\n\tnormalized := Normalize(platform)\n\treturn m.OS == normalized.OS &&\n\t\tm.Architecture == normalized.Architecture &&\n\t\tm.Variant == normalized.Variant\n}\n\nfunc (m *matcher) String() string {\n\treturn Format(m.Platform)\n}\n\n\/\/ Parse parses the platform specifier syntax into a platform declaration.\n\/\/\n\/\/ Platform specifiers are in the format <os|arch>[\/<arch>[\/<variant>]].

With a specifier, users\n\/\/ only need to specify the parts of the platform that are relevant to their\n\/\/ context, providing an operating system or architecture or both.\n\/\/\n\/\/ How do I use this package?\n\/\/\n\/\/ The vast majority of use cases should simply use the match function with\n\/\/ user input. The first step is to parse a specifier into a matcher:\n\/\/\n\/\/   m, err := Parse(\"linux\")\n\/\/   if err != nil { ... }\n\/\/\n\/\/ Once you have a matcher, use it to match against the platform declared by a\n\/\/ component, typically from an image or runtime. Since extracting an images\n\/\/ platform is a little more involved, we'll use an example against the\n\/\/ platform default:\n\/\/\n\/\/   if ok := m.Match(Default()); !ok { \/* doesn't match *\/ }\n\/\/\n\/\/ This can be composed in loops for resolving runtimes or used as a filter for\n\/\/ fetch and select images.\n\/\/\n\/\/ More details of the specifier syntax and platform spec follow.\n\/\/\n\/\/ Declaring Platform Support\n\/\/\n\/\/ Components that have strict platform requirements should use the OCI\n\/\/ platform specification to declare their support. Typically, this will be\n\/\/ images and runtimes that should make these declaring which platform they\n\/\/ support specifically. This looks roughly as follows:\n\/\/\n\/\/   type Platform struct {\n\/\/\t   Architecture string\n\/\/\t   OS           string\n\/\/\t   Variant      string\n\/\/   }\n\/\/\n\/\/ Most images and runtimes should at least set Architecture and OS, according\n\/\/ to their GOARCH and GOOS values, respectively (follow the OCI image\n\/\/ specification when in doubt). ARM should set variant under certain\n\/\/ discussions, which are outlined below.\n\/\/\n\/\/ Platform Specifiers\n\/\/\n\/\/ While the OCI platform specifications provide a tool for components to\n\/\/ specify structured information, user input typically doesn't need the full\n\/\/ context and much can be inferred. To solve this problem, we introduced\n\/\/ \"specifiers\". A specifier has the format\n\/\/ `<os>|<arch>|<os>\/<arch>[\/<variant>]`.  The user can provide either the\n\/\/ operating system or the architecture or both.\n\/\/\n\/\/ An example of a common specifier is `linux\/amd64`. If the host has a default\n\/\/ of runtime that matches this, the user can simply provide the component that\n\/\/ matters. For example, if a image provides amd64 and arm64 support, the\n\/\/ operating system, `linux` can be inferred, so they only have to provide\n\/\/ `arm64` or `amd64`. Similar behavior is implemented for operating systems,\n\/\/ where the architecture may be known but a runtime may support images from\n\/\/ different operating systems.\n\/\/\n\/\/ Normalization\n\/\/\n\/\/ Because not all users are familiar with the way the Go runtime represents\n\/\/ platforms, several normalizations have been provided to make this package\n\/\/ easier to user.\n\/\/\n\/\/ The following are performed for architectures:\n\/\/\n\/\/   Value    Normalized\n\/\/   aarch64  arm64\n\/\/   armhf    arm\n\/\/   armel    arm\/v6\n\/\/   i386     386\n\/\/   x86_64   amd64\n\/\/   x86-64   amd64\n\/\/\n\/\/ We also normalize the operating system `macos` to `darwin`.\n\/\/\n\/\/ ARM Support\n\/\/\n\/\/ To qualify ARM architecture, the Variant field is used to qualify the arm\n\/\/ version. The most common arm version, v7, is represented without the variant\n\/\/ unless it is explicitly provided. This is treated as equivalent to armhf. A\n\/\/ previous architecture, armel, will be normalized to arm\/v6.\n\/\/\n\/\/ While these normalizations are provided, their support on arm platforms has\n\/\/ not yet been fully implemented and tested.\npackage platforms\n\nimport (\n\t\"regexp\"\n\t\"runtime\"\n\t\"strings\"\n\n\t\"github.com\/containerd\/containerd\/errdefs\"\n\tspecs \"github.com\/opencontainers\/image-spec\/specs-go\/v1\"\n\t\"github.com\/pkg\/errors\"\n)\n\nvar (\n\tspecifierRe = regexp.MustCompile(`^[A-Za-z0-9_-]+$`)\n)\n\n\/\/ Matcher matches platforms specifications, provided by an image or runtime.\ntype Matcher interface {\n\tSpec() specs.Platform\n\tMatch(platform specs.Platform) bool\n}\n\ntype matcher struct {\n\tspecs.Platform\n}\n\nfunc (m *matcher) Spec() specs.Platform {\n\treturn m.Platform\n}\n\nfunc (m *matcher) Match(platform specs.Platform) bool {\n\tnormalized := Normalize(platform)\n\treturn m.OS == normalized.OS &&\n\t\tm.Architecture == normalized.Architecture &&\n\t\tm.Variant == normalized.Variant\n}\n\nfunc (m *matcher) String() string {\n\treturn Format(m.Platform)\n}\n\n\/\/ Parse parses the platform specifier syntax into a platform declaration.\n\/\/\n\/\/ Platform specifiers are in the format `<os>|<arch>|<os>\/<arch>[\/<variant>]`.\n\/\/ The minimum required information for a platform specifier is the operating\n\/\/ system or architecture.

You can find out more [in this document](\/docs\/guides\/gcp).\n\n### Batching\n\nIt's common to want to upload messages to Google Cloud Storage as batched\narchives, the easiest way to do this is to batch your messages at the output\nlevel and join the batch of messages with an\n`+\"[`archive`](\/docs\/components\/processors\/archive)\"+` and\/or\n`+\"[`compress`](\/docs\/components\/processors\/compress)\"+` processor.\n\nFor example, if we wished to upload messages as a .tar.gz archive of documents\nwe could achieve that with the following config:\n\n`+\"```yaml\"+`\noutput:\n  gcp_cloud_storage:\n    bucket: TODO\n    path: ${!count(\"files\")}-${!timestamp_unix_nano()}.tar.gz\n    batching:\n      count: 100\n      period: 10s\n      processors:\n        - archive:\n            format: tar\n        - compress:\n            algorithm: gzip\n`+\"```\"+`\n\nAlternatively, if we wished to upload JSON documents as a single large document\ncontaining an array of objects we can do that with:\n\n`+\"```yaml\"+`\noutput:\n  gcp_cloud_storage:\n    bucket: TODO\n    path: ${!count(\"files\")}-${!timestamp_unix_nano()}.json\n    batching:\n      count: 100\n      processors:\n        - archive:\n            format: json_array\n`+\"```\"+``),\n\t\tConfig: docs.FieldComponent().WithChildren(\n\t\t\tdocs.FieldCommon(\"bucket\", \"The bucket to upload messages to.\"),\n\t\t\tdocs.FieldCommon(\n\t\t\t\t\"path\", \"The path of each message to upload.\",\n\t\t\t\t`${!count(\"files\")}-${!timestamp_unix_nano()}.txt`,\n\t\t\t\t`${!meta(\"kafka_key\")}.json`,\n\t\t\t\t`${!json(\"doc.namespace\")}\/${!json(\"doc.id\")}.json`,\n\t\t\t).IsInterpolated(),\n\t\t\tdocs.FieldCommon(\"content_type\", \"The content type to set for each object.\").IsInterpolated(),\n\t\t\tdocs.FieldCommon(\"collision_mode\", `Determines how file path collisions should be dealt with.`).\n\t\t\t\tHasDefault(`overwrite`).\n\t\t\t\tHasAnnotatedOptions(\n\t\t\t\t\t\"overwrite\", \"Replace the existing file with the new one.\",\n\t\t\t\t\t\"append\", \"Append the message bytes to the original file.\",\n\t\t\t\t\t\"error-if-exists\", \"Return an error, this is the equivalent of a nack.\",\n\t\t\t\t\t\"ignore\", \"Do not modify the original file, the new data will be dropped.\",\n\t\t\t\t).AtVersion(\"3.53.0\"),\n\t\t\tdocs.FieldAdvanced(\"content_encoding\", \"An optional content encoding to set for each object.\").IsInterpolated(),\n\t\t\tdocs.FieldAdvanced(\"chunk_size\", \"An optional chunk size which controls the maximum number of bytes of the object that the Writer will attempt to send to the server in a single request.

A minimum of at least one policy statement is required for a signed URL.\n\/\/\n\/\/ Note: It is not safe to use Polices between multiple signers concurrently\n\/\/\n\/\/ Example:\n\/\/\n\/\/     \/\/ Sign URL to be valid for 30 minutes from now, expires one hour from now, and\n\/\/     \/\/ restricted to the 192.0.2.0\/24 IP address range.\n\/\/     policy := &sign.Policy{\n\/\/         Statements: []sign.Statement{\n\/\/             {\n\/\/                 Resource: rawURL,\n\/\/                 Condition: sign.Condition{\n\/\/                     \/\/ Optional IP source address range\n\/\/                     IPAddress: &sign.IPAddress{SourceIP: \"192.0.2.0\/24\"},\n\/\/                     \/\/ Optional date URL is not valid until\n\/\/                     DateGreaterThan: &sign.AWSEpochTime{time.Now().Add(30 * time.Minute)},\n\/\/                     \/\/ Required date the URL will expire after\n\/\/                     DateLessThan: &sign.AWSEpochTime{time.Now().Add(1 * time.Hour)},\n\/\/                 },\n\/\/             },\n\/\/         },\n\/\/     }\n\/\/\n\/\/     signer := sign.NewURLSigner(keyID, privKey)\n\/\/     signedURL, err := signer.SignWithPolicy(rawURL, policy)\n\/\/     if err != nil {\n\/\/         log.Fatalf(\"Failed to sign url, err: %s\\n\", err.Error())\n\/\/     }\n\/\/\nfunc (s URLSigner) SignWithPolicy(url string, p *Policy) (string, error) {\n\tscheme, cleanedURL, err := cleanURLScheme(url)\n\tif err != nil {\n\t\treturn \"\", err\n\t}\n\n\treturn signURL(scheme, cleanedURL, s.keyID, p, true, s.privKey)\n}\n\nfunc signURL(scheme, url, keyID string, p *Policy, customPolicy bool, privKey *rsa.PrivateKey) (string, error) {\n\t\/\/ Validation URL elements\n\tif err := validateURL(url); err != nil {\n\t\treturn \"\", err\n\t}\n\n\tb64Signature, b64Policy, err := p.Sign(privKey)\n\tif err != nil {\n\t\treturn \"\", err\n\t}\n\n\t\/\/ build and return signed URL\n\tbuiltURL := buildSignedURL(url, keyID, p, customPolicy, b64Policy, b64Signature)\n\tif scheme == \"rtmp\" {\n\t\treturn buildRTMPURL(builtURL)\n\t}\n\n\treturn builtURL, nil\n}\n\nfunc buildSignedURL(baseURL, keyID string, p *Policy, customPolicy bool, b64Policy, b64Signature []byte) string {\n\tpred := \"?\"\n\tif strings.Contains(baseURL, \"?\") {\n\t\tpred = \"&\"\n\t}\n\tsignedURL := baseURL + pred\n\n\tif customPolicy {\n\t\tsignedURL += \"Policy=\" + string(b64Policy)\n\t} else {\n\t\tsignedURL += fmt.Sprintf(\"Expires=%d\", p.Statements[0].Condition.DateLessThan.UTC().Unix())\n\t}\n\tsignedURL += fmt.Sprintf(\"&Signature=%s&Key-Pair-Id=%s\", string(b64Signature), keyID)\n\n\treturn signedURL\n}\n\nfunc buildRTMPURL(u string) (string, error) {\n\tparsed, err := url.Parse(u)\n\tif err != nil {\n\t\treturn \"\", fmt.Errorf(\"unable to parse rtmp signed URL, err: %s\", err)\n\t}\n\n\trtmpURL := strings.TrimLeft(parsed.Path, \"\/\")\n\tif parsed.RawQuery != \"\" {\n\t\trtmpURL = fmt.Sprintf(\"%s?%s\", rtmpURL, parsed.RawQuery)\n\t}\n\n\treturn rtmpURL, nil\n}\n\nfunc cleanURLScheme(u string) (scheme, cleanedURL string, err error) {\n\tparts := strings.SplitN(u, \":\/\/\", 2)\n\tif len(parts) != 2 {\n\t\treturn \"\", \"\", fmt.Errorf(\"invalid URL, missing scheme and domain\/path\")\n\t}\n\tscheme = strings.Replace(parts[0], \"*\", \"\", 1)\n\tcleanedURL = fmt.Sprintf(\"%s:\/\/%s\", scheme, parts[1])\n\n\treturn strings.ToLower(scheme), cleanedURL, nil\n}\n\nvar illegalQueryParms = []string{\"Expires\", \"Policy\", \"Signature\", \"Key-Pair-Id\"}\n\nfunc validateURL(u string) error {\n\tparsed, err := url.Parse(u)\n\tif err != nil {\n\t\treturn fmt.Errorf(\"unable to parse URL, err: %s\", err.Error())\n\t}\n\n\tif parsed.Scheme == \"\" {\n\t\treturn fmt.Errorf(\"URL missing valid scheme, %s\", u)\n\t}\n\n\tq := parsed.Query()\n\tfor _, p := range illegalQueryParms {\n\t\tif _, ok := q[p]; ok {\n\t\t\treturn fmt.Errorf(\"%s cannot be a query parameter for a signed URL\", p)\n\t\t}\n\t}\n\n\treturn nil\n}\n<|endoftext|>"}

RandomizationFactor, 1 + RandomizationFactor])\n\nIn other words NextBackOff() will range between the randomization factor\npercentage below and above the retry interval.\n\nFor example, given the following parameters:\n\n RetryInterval = 2\n RandomizationFactor = 0.5\n Multiplier = 2\n\nthe actual backoff period used in the next retry attempt will range between 1 and 3 seconds,\nmultiplied by the exponential, that is, between 2 and 6 seconds.\n\nNote: MaxInterval caps the RetryInterval and not the randomized interval.\n\nIf the time elapsed since an ExponentialBackOff instance is created goes past the\nMaxElapsedTime, then the method NextBackOff() starts returning backoff.Stop.\n\nThe elapsed time can be reset by calling Reset().\n\nExample: Given the following default arguments, for 10 tries the sequence will be,\nand assuming we go over the MaxElapsedTime on the 10th try:\n\n Request #  RetryInterval (seconds)  Randomized Interval (seconds)\n\n  1          0.5                     [0.25,   0.75]\n  2          0.75                    [0.375,  1.125]\n  3          1.125                   [0.562,  1.687]\n  4          1.687                   [0.8435, 2.53]\n  5          2.53                    [1.265,  3.795]\n  6          3.795                   [1.897,  5.692]\n  7          5.692                   [2.846,  8.538]\n  8          8.538                   [4.269, 12.807]\n  9         12.807                   [6.403, 19.210]\n 10         19.210                   backoff.Stop\n\nNote: Implementation is not thread-safe.\n*\/\ntype ExponentialBackOff struct {\n\tInitialInterval     time.Duration\n\tRandomizationFactor float64\n\tMultiplier          float64\n\tMaxInterval         time.Duration\n\t\/\/ After MaxElapsedTime the ExponentialBackOff stops.\n\t\/\/ It never stops if MaxElapsedTime == 0.\n\tMaxElapsedTime time.Duration\n\tClock          Clock\n\n\tcurrentInterval time.Duration\n\tstartTime       time.Time\n}\n\n\/\/ Clock is an interface that returns current time for BackOff.\ntype Clock interface {\n\tNow() time.Time\n}\n\n\/\/ Default values for ExponentialBackOff.\nconst (\n\tDefaultInitialInterval     = 500 * time.Millisecond\n\tDefaultRandomizationFactor = 0.5\n\tDefaultMultiplier          = 1.5\n\tDefaultMaxInterval         = 60 * time.Second\n\tDefaultMaxElapsedTime      = 15 * time.Minute\n)\n\n\/\/ withCanonicalRandomizationFactor is a utility function used by all\n\/\/ NewXYZBackoff functions to clamp b.RandomizationFactor to either 0 or 1\nfunc (b *ExponentialBackOff) withCanonicalRandomizationFactor() *ExponentialBackOff {\n\tif b.RandomizationFactor < 0 {\n\t\tb.RandomizationFactor = 0\n\t} else if b.RandomizationFactor > 1 {\n\t\tb.RandomizationFactor = 1\n\t}\n\treturn b\n}\n\n\/\/ withReset is a utility function that calls 'b.Reset()' and then returns it,\n\/\/ so that all NewXYZBackoff functions can reset their result and return it\n\/\/ inline\nfunc (b *ExponentialBackOff) withReset() *ExponentialBackOff {\n\tb.Reset()\n\treturn b\n}\n\n\/\/ NewExponentialBackOff creates an instance of ExponentialBackOff using default values.\nfunc NewExponentialBackOff() *ExponentialBackOff {\n\tb := &ExponentialBackOff{\n\t\tInitialInterval:     DefaultInitialInterval,\n\t\tRandomizationFactor: DefaultRandomizationFactor,\n\t\tMultiplier:          DefaultMultiplier,\n\t\tMaxInterval:         DefaultMaxInterval,\n\t\tMaxElapsedTime:      DefaultMaxElapsedTime,\n\t\tClock:               SystemClock,\n\t}\n\treturn b.withCanonicalRandomizationFactor().withReset()\n}\n\n\/\/ NewInfiniteBackOff creates an instance of ExponentialBackOff that never\n\/\/ ends.\nfunc NewInfiniteBackOff() *ExponentialBackOff {\n\tb := &ExponentialBackOff{\n\t\tInitialInterval:     DefaultInitialInterval,\n\t\tRandomizationFactor: DefaultRandomizationFactor,\n\t\tMultiplier:          DefaultMultiplier,\n\t\tMaxInterval:         15 * time.Second,\n\t\tMaxElapsedTime:      0,\n\t\tClock:               SystemClock,\n\t}\n\treturn b.withCanonicalRandomizationFactor().withReset()\n}\n\n\/\/ NewTestingBackOff returns a backoff tuned towards waiting for a Pachyderm\n\/\/ state change in a test\nfunc NewTestingBackOff() *ExponentialBackOff {\n\tb := &ExponentialBackOff{\n\t\tInitialInterval:     DefaultInitialInterval,\n\t\tRandomizationFactor: DefaultRandomizationFactor,\n\t\tMultiplier:          DefaultMultiplier,\n\t\tMaxInterval:         5 * time.Second,\n\t\tMaxElapsedTime:      60 * time.Second,\n\t\tClock:               SystemClock,\n\t}\n\treturn b.withCanonicalRandomizationFactor().withReset()\n}\n\n\/\/ New10sBackOff returns a backoff that's slightly more aggressive than\n\/\/ NewExponentialBackOff.

We want to follow redirects while still pipelining\n\/\/ requests, and we want to allow as many requests as possible to succeed\n\/\/ without retrying unnecessarily.\n\/\/\n\/\/ In particular, reads never need to redirect, and writes must always go to\n\/\/ the leader. So we want that read requests never retry, and write requests\n\/\/ retry if and only if necessary. Here's how it works:\n\/\/\n\/\/ In the proto.Conn, when we get a redirect response, we raise a flag noting\n\/\/ the new address. This flag only goes up, never down. This flag effectively\n\/\/ means the connection is deprecated. Any pending requests can go ahead, but\n\/\/ new requests should use the new address.\n\/\/\n\/\/ In the Client, when we notice that a redirect has occurred (i.e. the flag is\n\/\/ set), we establish a new connection to the new address.

So we want that read requests never retry, and write requests\n\/\/ retry if and only if necessary. Here's how it works:\n\/\/\n\/\/ In the proto.Conn, when we get a redirect response, we raise a flag noting\n\/\/ the new address. This flag only goes up, never down. This flag effectively\n\/\/ means the connection is deprecated. Any pending requests can go ahead, but\n\/\/ new requests should use the new address.\n\/\/\n\/\/ In the Client, when we notice that a redirect has occurred (i.e. the flag is\n\/\/ set), we establish a new connection to the new address. Calls in the future\n\/\/ will use the new connection. But we also allow the old connection to\n\/\/ continue functioning as it was.

Describe(\"Testing with ginkgo\"...)      \/\/ This is not a great description\n   It(\"TestDoesSoemthing\"...)              \/\/ This is a horrible description\n\n   Describe(\"create-user

The move\n\/\/CloseEmptySeats will automatically mark all currently unfilled seats as\n\/\/closed, so no new players will be accepted.\n\/\/\n\/\/It is NOT a FixUp move; it is a special move that is only every proposed by\n\/\/the server itself.\n\/\/\n\/\/boardgame:codegen\ntype SeatPlayer struct {\n\tDefault\n\tTargetPlayerIndex boardgame.PlayerIndex\n}\n\n\/\/DefaultsForState sets TargetPlayerIndex to the next player who is neither\n\/\/filled nor closed.\nfunc (s *SeatPlayer) DefaultsForState(state boardgame.ImmutableState) {\n\tvar index int\n\tfor index = 0; index < len(state.ImmutablePlayerStates()); index++ {\n\t\tplayer := state.ImmutablePlayerStates()[index]\n\t\tif seat, ok := player.(interfaces.Seater); ok {\n\t\t\tif seat.SeatIsClosed() || seat.SeatIsFilled() {\n\t\t\t\tcontinue\n\t\t\t}\n\t\t\ts.TargetPlayerIndex = boardgame.PlayerIndex(index)\n\t\t\treturn\n\t\t}\n\t}\n}\n\n\/\/Legal verifies that TargetPlayerIndex is set to a player who is both not\n\/\/filled and not closed, and that the proposer is the admin, since only server\n\/\/should propose this move.\nfunc (s *SeatPlayer) Legal(state boardgame.ImmutableState, proposer boardgame.PlayerIndex) error {\n\tif err := s.Default.Legal(state, proposer); err != nil {\n\t\treturn err\n\t}\n\tif proposer != boardgame.AdminPlayerIndex {\n\t\treturn errors.New(\"This move may only be proposed by an admin\")\n\t}\n\tif s.TargetPlayerIndex < 0 || int(s.TargetPlayerIndex) >= len(state.ImmutablePlayerStates()) {\n\t\treturn errors.New(\"TargetPlayerIndex is invalid\")\n\t}\n\tseat, ok := state.ImmutablePlayerStates()[s.TargetPlayerIndex].(interfaces.Seater)\n\tif !ok {\n\t\treturn errors.New(\"The selected player did not implement interfaces.Seater\")\n\t}\n\tif seat.SeatIsClosed() {\n\t\treturn errors.New(\"The selected seat was closed\")\n\t}\n\tif seat.SeatIsFilled() {\n\t\treturn errors.New(\"The selected seat was already filled\")\n\t}\n\treturn nil\n}\n\n\/\/Apply sets the targeted player to be Filled.

That means you are guaranteed that for a specific ID,\n\/\/\n\/\/ - The scheduler should, after creation, automatically call ExecutorFunc, when a task should run as defined by its Schedulable.\n\/\/\n\/\/ - the scheduler's should not be able to get into a state where blocks Release and Schedule indefinitely.\n\/\/\n\/\/ - Schedule should add a Schedulable to being scheduled, and Release should remove a task from being scheduled.\n\/\/\n\/\/ - Calling of ExecutorFunc should be serial in time on a per taskID basis. I.E.: the run at 12:00 will go before the run at 12:01.\n\/\/\n\/\/ Design:\n\/\/\n\/\/ The core of the scheduler is a btree keyed by time, a nonce, and a task ID, and a map keyed by task ID and containing a\n\/\/ nonce and a time (called a uniqueness index from now on).\n\/\/ The map is to ensure task uniqueness in the tree, so we can replace or delete tasks in the tree.\n\/\/\n\/\/ Scheduling in the tree consists of a main loop that feeds a fixed set of workers, each with their own communication channel.\n\/\/ Distribution is handled by hashing the TaskID (to ensure uniform distribution) and then distributing over those channels\n\/\/ evenly based on the hashed ID.  This is to ensure that all tasks of the same ID go to the same worker.\n\/\/\n\/\/The workers call ExecutorFunc handle any errors and update the LastScheduled time internally and also via the Checkpointer.\n\/\/\n\/\/ The main loop:\n\/\/\n\/\/ The main loop waits on a time.Timer to grab the task with the minimum time.  Once it successfully grabs a task ready\n\/\/ to trigger, it will start walking the btree from the item nearest\n\/\/\n\/\/ Putting a task into the scheduler:\n\/\/\n\/\/ Adding a task to the scheduler acquires a write lock, grabs the task from the uniqueness map, and replaces the item\n\/\/ in the uniqueness index and btree.
