See the +sections below for further details on formatting and configuration options. + +To dump a variable with full newlines, indentation, type, and pointer +information use Dump, Fdump, or Sdump: + spew.Dump(myVar1, myVar2, ...) + spew.Fdump(someWriter, myVar1, myVar2, ...) + str := spew.Sdump(myVar1, myVar2, ...) + +Alternatively, if you would prefer to use format strings with a compacted inline +printing style, use the convenience wrappers Printf, Fprintf, etc with +%v (most compact), %+v (adds pointer addresses), %#v (adds types), or +%#+v (adds types and pointer addresses): + spew.Printf("myVar1: %v -- myVar2: %+v", myVar1, myVar2) + spew.Printf("myVar3: %#v -- myVar4: %#+v", myVar3, myVar4) + spew.Fprintf(someWriter, "myVar1: %v -- myVar2: %+v", myVar1, myVar2) + spew.Fprintf(someWriter, "myVar3: %#v -- myVar4: %#+v", myVar3, myVar4) + +Configuration Options + +Configuration of spew is handled by fields in the ConfigState type. For +convenience, all of the top-level functions use a global state available +via the spew.Config global. + +It is also possible to create a ConfigState instance that provides methods +equivalent to the top-level functions. This allows concurrent configuration +options. See the ConfigState documentation for more details. + +The following configuration options are available: + * Indent + String to use for each indentation level for Dump functions. + It is a single space by default. A popular alternative is "\t". + + * MaxDepth + Maximum number of levels to descend into nested data structures. + There is no limit by default. + + * DisableMethods + Disables invocation of error and Stringer interface methods. + Method invocation is enabled by default. + + * DisablePointerMethods + Disables invocation of error and Stringer interface methods on types + which only accept pointer receivers from non-pointer variables. + Pointer method invocation is enabled by default. + + * DisablePointerAddresses + DisablePointerAddresses specifies whether to disable the printing of + pointer addresses. This is useful when diffing data structures in tests. + + * DisableCapacities + DisableCapacities specifies whether to disable the printing of + capacities for arrays, slices, maps and channels. This is useful when + diffing data structures in tests. + + * ContinueOnMethod + Enables recursion into types after invoking error and Stringer interface + methods. Recursion after method invocation is disabled by default. + + * SortKeys + Specifies map keys should be sorted before being printed. Use + this to have a more deterministic, diffable output. Note that + only native types (bool, int, uint, floats, uintptr and string) + and types which implement error or Stringer interfaces are + supported with other types sorted according to the + reflect.Value.String() output which guarantees display + stability. Natural map order is used by default. + + * SpewKeys + Specifies that, as a last resort attempt, map keys should be + spewed to strings and sorted by those strings. This is only + considered if SortKeys is true. + +Dump Usage + +Simply call spew.Dump with a list of variables you want to dump: + + spew.Dump(myVar1, myVar2, ...) + +You may also call spew.Fdump if you would prefer to output to an arbitrary +io.Writer. For example, to dump to standard error: + + spew.Fdump(os.Stderr, myVar1, myVar2, ...) + +A third option is to call spew.Sdump to get the formatted output as a string: + + str := spew.Sdump(myVar1, myVar2, ...) + +Sample Dump Output + +See the Dump example for details on the setup of the types and variables being +shown here. + + (main.Foo) { + unexportedField: (*main.Bar)(0xf84002e210)({ + flag: (main.Flag) flagTwo, + data: (uintptr) + }), + ExportedField: (map[interface {}]interface {}) (len=1) { + (string) (len=3) "one": (bool) true + } + } + +Byte (and uint8) arrays and slices are displayed uniquely like the hexdump -C +command as shown. + ([]uint8) (len=32 cap=32) { + 00000000 11 12 13 14 15 16 17 18 19 1a 1b 1c 1d 1e 1f 20 |............... | + 00000010 21 22 23 24 25 26 27 28 29 2a 2b 2c 2d 2e 2f 30 |!"#$%&'()*+,-./0| + 00000020 31 32 |12| + } + +Custom Formatter + +Spew provides a custom formatter that implements the fmt.Formatter interface +so that it integrates cleanly with standard fmt package printing functions. The +formatter is useful for inline printing of smaller data types similar to the +standard %v format specifier. + +The custom formatter only responds to the %v (most compact), %+v (adds pointer +addresses), %#v (adds types), or %#+v (adds types and pointer addresses) verb +combinations. Any other verbs such as %x and %q will be sent to the the +standard fmt package for formatting. In addition, the custom formatter ignores +the width and precision arguments (however they will still work on the format +specifiers not handled by the custom formatter). + +Custom Formatter Usage + +The simplest way to make use of the spew custom formatter is to call one of the +convenience functions such as spew.Printf, spew.Println, or spew.Printf. The +functions have syntax you are most likely already familiar with: + + spew.Printf("myVar1: %v -- myVar2: %+v", myVar1, myVar2) + spew.Printf("myVar3: %#v -- myVar4: %#+v", myVar3, myVar4) + spew.Println(myVar, myVar2) + spew.Fprintf(os.Stderr, "myVar1: %v -- myVar2: %+v", myVar1, myVar2) + spew.Fprintf(os.Stderr, "myVar3: %#v -- myVar4: %#+v", myVar3, myVar4) + +See the Index for the full list convenience functions. + +Sample Formatter Output + +Double pointer to a uint8: + %v: <**>5 + %+v: <**>(0xf8400420d0->0xf8400420c8)5 + %#v: (**uint8)5 + %#+v: (**uint8)(0xf8400420d0->0xf8400420c8)5 + +Pointer to circular struct with a uint8 field and a pointer to itself: + %v: <*>{1 <*>} + %+v: <*>(0xf84003e260){ui8:1 c:<*>(0xf84003e260)} + %#v: (*main.circular){ui8:(uint8)1 c:(*main.circular)} + %#+v: (*main.circular)(0xf84003e260){ui8:(uint8)1 c:(*main.circular)(0xf84003e260)} + +See the Printf example for details on the setup of variables being shown +here. + +Errors + +Since it is possible for custom Stringer/error interfaces to panic, spew +detects them and handles them internally by printing the panic information +inline with the output.

The messageType argument to the +// WriteMessage and NextWriter methods specifies the type of a sent message. +// +// It is the application's responsibility to ensure that text messages are +// valid UTF-8 encoded text. +// +// Control Messages +// +// The WebSocket protocol defines three types of control messages: close, ping +// and pong. Call the connection WriteControl, WriteMessage or NextWriter +// methods to send a control message to the peer. +// +// Connections handle received close messages by calling the handler function +// set with the SetCloseHandler method and by returning a *CloseError from the +// NextReader, ReadMessage or the message Read method. The default close +// handler sends a close message to the peer. +// +// Connections handle received ping messages by calling the handler function +// set with the SetPingHandler method. The default ping handler sends a pong +// message to the peer. +// +// Connections handle received pong messages by calling the handler function +// set with the SetPongHandler method. The default pong handler does nothing. +// If an application sends ping messages, then the application should set a +// pong handler to receive the corresponding pong. +// +// The control message handler functions are called from the NextReader, +// ReadMessage and message reader Read methods. The default close and ping +// handlers can block these methods for a short time when the handler writes to +// the connection. +// +// The application must read the connection to process close, ping and pong +// messages sent from the peer. If the application is not otherwise interested +// in messages from the peer, then the application should start a goroutine to +// read and discard messages from the peer. A simple example is: +// +// func readLoop(c *websocket.Conn) { +// for { +// if _, _, err := c.NextReader(); err != nil { +// c.Close() +// break +// } +// } +// } +// +// Concurrency +// +// Connections support one concurrent reader and one concurrent writer. +// +// Applications are responsible for ensuring that no more than one goroutine +// calls the write methods (NextWriter, SetWriteDeadline, WriteMessage, +// WriteJSON, EnableWriteCompression, SetCompressionLevel) concurrently and +// that no more than one goroutine calls the read methods (NextReader, +// SetReadDeadline, ReadMessage, ReadJSON, SetPongHandler, SetPingHandler) +// concurrently. +// +// The Close and WriteControl methods can be called concurrently with all other +// methods. +// +// Origin Considerations +// +// Web browsers allow Javascript applications to open a WebSocket connection to +// any host. It's up to the server to enforce an origin policy using the Origin +// request header sent by the browser. +// +// The Upgrader calls the function specified in the CheckOrigin field to check +// the origin. If the CheckOrigin function returns false, then the Upgrade +// method fails the WebSocket handshake with HTTP status 403. +// +// If the CheckOrigin field is nil, then the Upgrader uses a safe default: fail +// the handshake if the Origin request header is present and the Origin host is +// not equal to the Host request header. +// +// The deprecated package-level Upgrade function does not perform origin +// checking. The application is responsible for checking the Origin header +// before calling the Upgrade function. +// +// Buffers +// +// Connections buffer network input and output to reduce the number +// of system calls when reading or writing messages. +// +// Write buffers are also used for constructing WebSocket frames. See RFC 6455, +// Section 5 for a discussion of message framing. A WebSocket frame header is +// written to the network each time a write buffer is flushed to the network. +// Decreasing the size of the write buffer can increase the amount of framing +// overhead on the connection. +// +// The buffer sizes in bytes are specified by the ReadBufferSize and +// WriteBufferSize fields in the Dialer and Upgrader. The Dialer uses a default +// size of 4096 when a buffer size field is set to zero. The Upgrader reuses +// buffers created by the HTTP server when a buffer size field is set to zero. +// The HTTP server buffers have a size of 4096 at the time of this writing. +// +// The buffer sizes do not limit the size of a message that can be read or +// written by a connection. +// +// Buffers are held for the lifetime of the connection by default. If the +// Dialer or Upgrader WriteBufferPool field is set, then a connection holds the +// write buffer only when writing a message. +// +// Applications should tune the buffer sizes to balance memory use and +// performance. Increasing the buffer size uses more memory, but can reduce the +// number of system calls to read or write the network. In the case of writing, +// increasing the buffer size can reduce the number of frame headers written to +// the network. +// +// Some guidelines for setting buffer parameters are: +// +// Limit the buffer sizes to the maximum expected message size. Buffers larger +// than the largest message do not provide any benefit. +// +// Depending on the distribution of message sizes, setting the buffer size to +// a value less than the maximum expected message size can greatly reduce memory +// use with a small impact on performance. Here's an example: If 99% of the +// messages are smaller than 256 bytes and the maximum message size is 512 +// bytes, then a buffer size of 256 bytes will result in 1.01 more system calls +// than a buffer size of 512 bytes. The memory savings is 50%. +// +// A write buffer pool is useful when the application has a modest number +// writes over a large number of connections. when buffers are pooled, a larger +// buffer size has a reduced impact on total memory use and has the benefit of +// reducing system calls and frame overhead. +// +// Compression EXPERIMENTAL +// +// Per message compression extensions (RFC 7692) are experimentally supported +// by this package in a limited capacity. Setting the EnableCompression option +// to true in Dialer or Upgrader will attempt to negotiate per message deflate +// support. +// +// var upgrader = websocket.Upgrader{ +// EnableCompression: true, +// } +// +// If compression was successfully negotiated with the connection's peer, any +// message received in compressed form will be automatically decompressed. +// All Read methods will return uncompressed bytes. +// +// Per message compression of messages written to a connection can be enabled +// or disabled by calling the corresponding Conn method: +// +// conn.EnableWriteCompression(false) +// +// Currently this package does not support compression with "context takeover". +// This means that messages must be compressed and decompressed in isolation, +// without retaining sliding window or dictionary state across messages. For +// more details refer to RFC 7692. +// +// Use of compression is experimental and may result in decreased performance. +package websocket diff --git a/vendor/github.com/gorilla/websocket/join.go b/vendor/github.com/gorilla/websocket/join.go new file mode 100644 index 00000000..c64f8c82 --- /dev/null +++ b/vendor/github.com/gorilla/websocket/join.go @@ -0,0 +1,42 @@ +// Copyright 2019 The Gorilla WebSocket Authors.

Consider +alternatives such as +[x/exp/rand](https://pkg.go.dev/golang.org/x/exp/rand#LockedSource). +Security-sensitive use cases should always use cryptographically secure entropy +provided by [crypto/rand](https://pkg.go.dev/crypto/rand). + +Performance-sensitive use cases should avoid synchronization when generating +IDs. One option is to use a unique source of entropy for each concurrent +goroutine, which results in no lock contention, but cannot provide strong +guarantees about the random data, and does not provide monotonicity within a +given millisecond. One common performance optimization is to pool sources of +entropy using a [sync.Pool](https://pkg.go.dev/sync#Pool). + +Monotonicity is a property that says each ULID is "bigger than" the previous +one. ULIDs are automatically monotonic, but only to millisecond precision. ULIDs +generated within the same millisecond are ordered by their random component, +which means they are by default un-ordered. You can use +[ulid.MonotonicEntropy](https://pkg.go.dev/oklog/ulid/v2#MonotonicEntropy) or +[ulid.LockedMonotonicEntropy](https://pkg.go.dev/oklog/ulid/v2#LockedMonotonicEntropy) +to create ULIDs that are monotonic within a given millisecond, with caveats. See +the documentation for details. + +If you don't care about time-based ordering of generated IDs, then there's no +reason to use ULIDs!

It was developed within [Canonical](https://www.canonical.com) as +part of the [juju](https://juju.ubuntu.com) project, and is based on a +pure Go port of the well-known [libyaml](http://pyyaml.org/wiki/LibYAML) +C library to parse and generate YAML data quickly and reliably. + +Compatibility +------------- + +The yaml package supports most of YAML 1.2, but preserves some behavior +from 1.1 for backwards compatibility. + +Specifically, as of v3 of the yaml package: + + - YAML 1.1 bools (_yes/no, on/off_) are supported as long as they are being + decoded into a typed bool value. Otherwise they behave as a string. Booleans + in YAML 1.2 are _true/false_ only. + - Octals encode and decode as _0777_ per YAML 1.1, rather than _0o777_ + as specified in YAML 1.2, because most parsers still use the old format. + Octals in the _0o777_ format are supported though, so new files work. + - Does not support base-60 floats. These are gone from YAML 1.2, and were + actually never supported by this package as it's clearly a poor choice. + +and offers backwards +compatibility with YAML 1.1 in some cases. +1.2, including support for +anchors, tags, map merging, etc. Multi-document unmarshalling is not yet +implemented, and base-60 floats from YAML 1.1 are purposefully not +supported since they're a poor design and are gone in YAML 1.2. + +Installation and usage +---------------------- + +The import path for the package is *gopkg.in/yaml.v3*. + +To install it, run: + + go get gopkg.in/yaml.v3 + +API documentation +----------------- + +If opened in a browser, the import path itself leads to the API documentation: + + - [https://gopkg.in/yaml.v3](https://gopkg.in/yaml.v3) + +API stability +------------- + +The package API for yaml v3 will remain stable as described in [gopkg.in](https://gopkg.in). + + +License +------- + +The yaml package is licensed under the MIT and Apache License 2.0 licenses. +Please see the LICENSE file for details. + + +Example +------- + +```Go +package main + +import ( + "fmt" + "log" + + "gopkg.in/yaml.v3" +) + +var data = ` +a: Easy! +b: + c: 2 + d: [3, 4] +` + +// Note: struct fields must be public in order for unmarshal to +// correctly populate the data. +type T struct { + A string + B struct { + RenamedC int `yaml:"c"` + D []int `yaml:",flow"` + } +} + +func main() { + t := T{} + + err := yaml.Unmarshal([]byte(data), &t) + if err != nil { + log.Fatalf("error: %v", err) + } + fmt.Printf("--- t:\n%v\n\n", t) + + d, err := yaml.Marshal(&t) + if err != nil { + log.Fatalf("error: %v", err) + } + fmt.Printf("--- t dump:\n%s\n\n", string(d)) + + m := make(map[interface{}]interface{}) + + err = yaml.Unmarshal([]byte(data), &m) + if err != nil { + log.Fatalf("error: %v", err) + } + fmt.Printf("--- m:\n%v\n\n", m) + + d, err = yaml.Marshal(&m) + if err != nil { + log.Fatalf("error: %v", err) + } + fmt.Printf("--- m dump:\n%s\n\n", string(d)) +} +``` + +This example will generate the following output: + +``` +--- t: +{Easy! {2 [3 4]}} + +--- t dump: +a: Easy! +b: + c: 2 + d: [3, 4] + + +--- m: +map[a:Easy! b:map[c:2 d:[3 4]]] + +--- m dump: +a: Easy! +b: + c: 2 + d: + - 3 + - 4 +``` + diff --git a/vendor/gopkg.in/yaml.v3/apic.go b/vendor/gopkg.in/yaml.v3/apic.go new file mode 100644 index 00000000..65846e67 --- /dev/null +++ b/vendor/gopkg.in/yaml.v3/apic.go @@ -0,0 +1,746 @@ +// +// Copyright (c) 2011-2019 Canonical Ltd +// Copyright (c) 2006-2010 Kirill Simonov +// +// Permission is hereby granted, free of charge, to any person obtaining a copy of +// this software and associated documentation files (the "Software"), to deal in +// the Software without restriction, including without limitation the rights to +// use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies +// of the Software, and to permit persons to whom the Software is furnished to do +// so, subject to the following conditions: +// +// The above copyright notice and this permission notice shall be included in all +// copies or substantial portions of the Software. +// +// THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR +// IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, +// FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

We mostly follow it, although in +// some cases we are less restrictive that it requires. +// +// The process of transforming a YAML stream into a sequence of events is +// divided on two steps: Scanning and Parsing. +// +// The Scanner transforms the input stream into a sequence of tokens, while the +// parser transform the sequence of tokens produced by the Scanner into a +// sequence of parsing events. +// +// The Scanner is rather clever and complicated. The Parser, on the contrary, +// is a straightforward implementation of a recursive-descendant parser (or, +// LL(1) parser, as it is usually called). +// +// Actually there are two issues of Scanning that might be called "clever", the +// rest is quite straightforward. The issues are "block collection start" and +// "simple keys". Both issues are explained below in details. +// +// Here the Scanning step is explained and implemented. We start with the list +// of all the tokens produced by the Scanner together with short descriptions. +// +// Now, tokens: +// +// STREAM-START(encoding) # The stream start. +// STREAM-END # The stream end. +// VERSION-DIRECTIVE(major,minor) # The '%YAML' directive. +// TAG-DIRECTIVE(handle,prefix) # The '%TAG' directive. +// DOCUMENT-START # '---' +// DOCUMENT-END # '...' +// BLOCK-SEQUENCE-START # Indentation increase denoting a block +// BLOCK-MAPPING-START # sequence or a block mapping. +// BLOCK-END # Indentation decrease. +// FLOW-SEQUENCE-START # '[' +// FLOW-SEQUENCE-END # ']' +// BLOCK-SEQUENCE-START # '{' +// BLOCK-SEQUENCE-END # '}' +// BLOCK-ENTRY # '-' +// FLOW-ENTRY # ',' +// KEY # '?' or nothing (simple keys). +// VALUE # ':' +// ALIAS(anchor) # '*anchor' +// ANCHOR(anchor) # '&anchor' +// TAG(handle,suffix) # '!handle!suffix' +// SCALAR(value,style) # A scalar. +// +// The following two tokens are "virtual" tokens denoting the beginning and the +// end of the stream: +// +// STREAM-START(encoding) +// STREAM-END +// +// We pass the information about the input stream encoding with the +// STREAM-START token. +// +// The next two tokens are responsible for tags: +// +// VERSION-DIRECTIVE(major,minor) +// TAG-DIRECTIVE(handle,prefix) +// +// Example: +// +// %YAML 1.1 +// %TAG ! !foo +// %TAG !yaml! tag:yaml.org,2002: +// --- +// +// The correspoding sequence of tokens: +// +// STREAM-START(utf-8) +// VERSION-DIRECTIVE(1,1) +// TAG-DIRECTIVE("!","!foo") +// TAG-DIRECTIVE("!yaml","tag:yaml.org,2002:") +// DOCUMENT-START +// STREAM-END +// +// Note that the VERSION-DIRECTIVE and TAG-DIRECTIVE tokens occupy a whole +// line. +// +// The document start and end indicators are represented by: +// +// DOCUMENT-START +// DOCUMENT-END +// +// Note that if a YAML stream contains an implicit document (without '---' +// and '...' indicators), no DOCUMENT-START and DOCUMENT-END tokens will be +// produced. +// +// In the following examples, we present whole documents together with the +// produced tokens. +// +// 1.

- -Notes: - -1. Large messages are fragmented in [Chrome's new WebSocket implementation](http://www.ietf.org/mail-archive/web/hybi/current/msg10503.html). -2. The application can get the type of a received data message by implementing - a [Codec marshal](http://godoc.org/golang.org/x/net/websocket#Codec.Marshal) - function. -3. The go.net io.Reader and io.Writer operate across WebSocket frame boundaries. - Read returns when the input buffer is full or a frame boundary is - encountered. Each call to Write sends a single frame message. The Gorilla - io.Reader and io.WriteCloser operate on a single WebSocket message. - diff --git a/vendor/github.com/gorilla/websocket/client.go b/vendor/github.com/gorilla/websocket/client.go deleted file mode 100644 index 962c06a3..00000000 --- a/vendor/github.com/gorilla/websocket/client.go +++ /dev/null @@ -1,395 +0,0 @@ -// Copyright 2013 The Gorilla WebSocket Authors.

The interpretation of -// binary messages is left to the application. -// -// This package uses the TextMessage and BinaryMessage integer constants to -// identify the two data message types. The ReadMessage and NextReader methods -// return the type of the received message. The messageType argument to the -// WriteMessage and NextWriter methods specifies the type of a sent message. -// -// It is the application's responsibility to ensure that text messages are -// valid UTF-8 encoded text. -// -// Control Messages -// -// The WebSocket protocol defines three types of control messages: close, ping -// and pong. Call the connection WriteControl, WriteMessage or NextWriter -// methods to send a control message to the peer. -// -// Connections handle received close messages by calling the handler function -// set with the SetCloseHandler method and by returning a *CloseError from the -// NextReader, ReadMessage or the message Read method. The default close -// handler sends a close message to the peer. -// -// Connections handle received ping messages by calling the handler function -// set with the SetPingHandler method. The default ping handler sends a pong -// message to the peer. -// -// Connections handle received pong messages by calling the handler function -// set with the SetPongHandler method. The default pong handler does nothing. -// If an application sends ping messages, then the application should set a -// pong handler to receive the corresponding pong. -// -// The control message handler functions are called from the NextReader, -// ReadMessage and message reader Read methods. The default close and ping -// handlers can block these methods for a short time when the handler writes to -// the connection. -// -// The application must read the connection to process close, ping and pong -// messages sent from the peer. If the application is not otherwise interested -// in messages from the peer, then the application should start a goroutine to -// read and discard messages from the peer. A simple example is: -// -// func readLoop(c *websocket.Conn) { -// for { -// if _, _, err := c.NextReader(); err != nil { -// c.Close() -// break -// } -// } -// } -// -// Concurrency -// -// Connections support one concurrent reader and one concurrent writer. -// -// Applications are responsible for ensuring that no more than one goroutine -// calls the write methods (NextWriter, SetWriteDeadline, WriteMessage, -// WriteJSON, EnableWriteCompression, SetCompressionLevel) concurrently and -// that no more than one goroutine calls the read methods (NextReader, -// SetReadDeadline, ReadMessage, ReadJSON, SetPongHandler, SetPingHandler) -// concurrently. -// -// The Close and WriteControl methods can be called concurrently with all other -// methods. -// -// Origin Considerations -// -// Web browsers allow Javascript applications to open a WebSocket connection to -// any host. It's up to the server to enforce an origin policy using the Origin -// request header sent by the browser. -// -// The Upgrader calls the function specified in the CheckOrigin field to check -// the origin. If the CheckOrigin function returns false, then the Upgrade -// method fails the WebSocket handshake with HTTP status 403. -// -// If the CheckOrigin field is nil, then the Upgrader uses a safe default: fail -// the handshake if the Origin request header is present and the Origin host is -// not equal to the Host request header. -// -// The deprecated package-level Upgrade function does not perform origin -// checking. The application is responsible for checking the Origin header -// before calling the Upgrade function. -// -// Buffers -// -// Connections buffer network input and output to reduce the number -// of system calls when reading or writing messages. -// -// Write buffers are also used for constructing WebSocket frames. See RFC 6455, -// Section 5 for a discussion of message framing. A WebSocket frame header is -// written to the network each time a write buffer is flushed to the network. -// Decreasing the size of the write buffer can increase the amount of framing -// overhead on the connection. -// -// The buffer sizes in bytes are specified by the ReadBufferSize and -// WriteBufferSize fields in the Dialer and Upgrader. The Dialer uses a default -// size of 4096 when a buffer size field is set to zero. The Upgrader reuses -// buffers created by the HTTP server when a buffer size field is set to zero. -// The HTTP server buffers have a size of 4096 at the time of this writing. -// -// The buffer sizes do not limit the size of a message that can be read or -// written by a connection. -// -// Buffers are held for the lifetime of the connection by default. If the -// Dialer or Upgrader WriteBufferPool field is set, then a connection holds the -// write buffer only when writing a message. -// -// Applications should tune the buffer sizes to balance memory use and -// performance. Increasing the buffer size uses more memory, but can reduce the -// number of system calls to read or write the network. In the case of writing, -// increasing the buffer size can reduce the number of frame headers written to -// the network. -// -// Some guidelines for setting buffer parameters are: -// -// Limit the buffer sizes to the maximum expected message size. Buffers larger -// than the largest message do not provide any benefit. -// -// Depending on the distribution of message sizes, setting the buffer size to -// a value less than the maximum expected message size can greatly reduce memory -// use with a small impact on performance. Here's an example: If 99% of the -// messages are smaller than 256 bytes and the maximum message size is 512 -// bytes, then a buffer size of 256 bytes will result in 1.01 more system calls -// than a buffer size of 512 bytes. The memory savings is 50%. -// -// A write buffer pool is useful when the application has a modest number -// writes over a large number of connections. when buffers are pooled, a larger -// buffer size has a reduced impact on total memory use and has the benefit of -// reducing system calls and frame overhead. -// -// Compression EXPERIMENTAL -// -// Per message compression extensions (RFC 7692) are experimentally supported -// by this package in a limited capacity. Setting the EnableCompression option -// to true in Dialer or Upgrader will attempt to negotiate per message deflate -// support. -// -// var upgrader = websocket.Upgrader{ -// EnableCompression: true, -// } -// -// If compression was successfully negotiated with the connection's peer, any -// message received in compressed form will be automatically decompressed. -// All Read methods will return uncompressed bytes. -// -// Per message compression of messages written to a connection can be enabled -// or disabled by calling the corresponding Conn method: -// -// conn.EnableWriteCompression(false) -// -// Currently this package does not support compression with "context takeover". -// This means that messages must be compressed and decompressed in isolation, -// without retaining sliding window or dictionary state across messages.

Consider -alternatives such as -[x/exp/rand](https://pkg.go.dev/golang.org/x/exp/rand#LockedSource). -Security-sensitive use cases should always use cryptographically secure entropy -provided by [crypto/rand](https://pkg.go.dev/crypto/rand). - -Performance-sensitive use cases should avoid synchronization when generating -IDs. One option is to use a unique source of entropy for each concurrent -goroutine, which results in no lock contention, but cannot provide strong -guarantees about the random data, and does not provide monotonicity within a -given millisecond. One common performance optimization is to pool sources of -entropy using a [sync.Pool](https://pkg.go.dev/sync#Pool). - -Monotonicity is a property that says each ULID is "bigger than" the previous -one. ULIDs are automatically monotonic, but only to millisecond precision. ULIDs -generated within the same millisecond are ordered by their random component, -which means they are by default un-ordered. You can use -[ulid.MonotonicEntropy](https://pkg.go.dev/oklog/ulid/v2#MonotonicEntropy) or -[ulid.LockedMonotonicEntropy](https://pkg.go.dev/oklog/ulid/v2#LockedMonotonicEntropy) -to create ULIDs that are monotonic within a given millisecond, with caveats. See -the documentation for details. - -If you don't care about time-based ordering of generated IDs, then there's no -reason to use ULIDs! There are many other kinds of IDs that are easier, faster, -smaller, etc. Consider UUIDs. - -## Commandline tool - -This repo also provides a tool to generate and parse ULIDs at the command line. -These commands should install the latest version of the tool at `bin/ulid`: - -```shell -cd $(mktemp -d) -env GOPATH=$(pwd) GO111MODULE=on go get -v github.com/oklog/ulid/v2/cmd/ulid -``` - -Usage: - -```shell -Usage: ulid [-hlqz] [-f ] [parameters ...] - -f, --format= when parsing, show times in this format: default, rfc3339, unix, ms - -h, --help print this help text - -l, --local when parsing, show local time instead of UTC - -q, --quick when generating, use non-crypto-grade entropy - -z, --zero when generating, fix entropy to all-zeroes -``` - -Examples: - -```shell -$ ulid -01D78XYFJ1PRM1WPBCBT3VHMNV -$ ulid -z -01D78XZ44G0000000000000000 -$ ulid 01D78XZ44G0000000000000000 -Sun Mar 31 03:51:23.536 UTC 2019 -$ ulid --format=rfc3339 --local 01D78XZ44G0000000000000000 -2019-03-31T05:51:23.536+02:00 -``` - -## Specification - -Below is the current specification of ULID as implemented in this repository. - -### Components - -**Timestamp** -- 48 bits -- UNIX-time in milliseconds -- Won't run out of space till the year 10889 AD - -**Entropy** -- 80 bits -- User defined entropy source. -- Monotonicity within the same millisecond with [`ulid.Monotonic`](https://godoc.org/github.com/oklog/ulid#Monotonic) - -### Encoding - -[Crockford's Base32](http://www.crockford.com/wrmg/base32.html) is used as shown. -This alphabet excludes the letters I, L, O, and U to avoid confusion and abuse. - -``` -0123456789ABCDEFGHJKMNPQRSTVWXYZ -``` - -### Binary Layout and Byte Order - -The components are encoded as 16 octets.

We start with the list -// of all the tokens produced by the Scanner together with short descriptions. -// -// Now, tokens: -// -// STREAM-START(encoding) # The stream start. -// STREAM-END # The stream end. -// VERSION-DIRECTIVE(major,minor) # The '%YAML' directive. -// TAG-DIRECTIVE(handle,prefix) # The '%TAG' directive. -// DOCUMENT-START # '---' -// DOCUMENT-END # '...' -// BLOCK-SEQUENCE-START # Indentation increase denoting a block -// BLOCK-MAPPING-START # sequence or a block mapping. -// BLOCK-END # Indentation decrease. -// FLOW-SEQUENCE-START # '[' -// FLOW-SEQUENCE-END # ']' -// BLOCK-SEQUENCE-START # '{' -// BLOCK-SEQUENCE-END # '}' -// BLOCK-ENTRY # '-' -// FLOW-ENTRY # ',' -// KEY # '?' or nothing (simple keys). -// VALUE # ':' -// ALIAS(anchor) # '*anchor' -// ANCHOR(anchor) # '&anchor' -// TAG(handle,suffix) # '!handle!suffix' -// SCALAR(value,style) # A scalar. -// -// The following two tokens are "virtual" tokens denoting the beginning and the -// end of the stream: -// -// STREAM-START(encoding) -// STREAM-END -// -// We pass the information about the input stream encoding with the -// STREAM-START token. -// -// The next two tokens are responsible for tags: -// -// VERSION-DIRECTIVE(major,minor) -// TAG-DIRECTIVE(handle,prefix) -// -// Example: -// -// %YAML 1.1 -// %TAG ! !foo -// %TAG !yaml! tag:yaml.org,2002: -// --- -// -// The correspoding sequence of tokens: -// -// STREAM-START(utf-8) -// VERSION-DIRECTIVE(1,1) -// TAG-DIRECTIVE("!","!foo") -// TAG-DIRECTIVE("!yaml","tag:yaml.org,2002:") -// DOCUMENT-START -// STREAM-END -// -// Note that the VERSION-DIRECTIVE and TAG-DIRECTIVE tokens occupy a whole -// line. -// -// The document start and end indicators are represented by: -// -// DOCUMENT-START -// DOCUMENT-END -// -// Note that if a YAML stream contains an implicit document (without '---' -// and '...' indicators), no DOCUMENT-START and DOCUMENT-END tokens will be -// produced. -// -// In the following examples, we present whole documents together with the -// produced tokens. -// -// 1. An implicit document: -// -// 'a scalar' -// -// Tokens: -// -// STREAM-START(utf-8) -// SCALAR("a scalar",single-quoted) -// STREAM-END -// -// 2. An explicit document: -// -// --- -// 'a scalar' -// ... -// -// Tokens: -// -// STREAM-START(utf-8) -// DOCUMENT-START -// SCALAR("a scalar",single-quoted) -// DOCUMENT-END -// STREAM-END -// -// 3. Several documents in a stream: -// -// 'a scalar' -// --- -// 'another scalar' -// --- -// 'yet another scalar' -// -// Tokens: -// -// STREAM-START(utf-8) -// SCALAR("a scalar",single-quoted) -// DOCUMENT-START -// SCALAR("another scalar",single-quoted) -// DOCUMENT-START -// SCALAR("yet another scalar",single-quoted) -// STREAM-END -// -// We have already introduced the SCALAR token above. The following tokens are -// used to describe aliases, anchors, tag, and scalars: -// -// ALIAS(anchor) -// ANCHOR(anchor) -// TAG(handle,suffix) -// SCALAR(value,style) -// -// The following series of examples illustrate the usage of these tokens: -// -// 1. A recursive sequence: -// -// &A [ *A ] -// -// Tokens: -// -// STREAM-START(utf-8) -// ANCHOR("A") -// FLOW-SEQUENCE-START -// ALIAS("A") -// FLOW-SEQUENCE-END -// STREAM-END -// -// 2. A tagged scalar: -// -// !!float "3.14" # A good approximation. -// -// Tokens: -// -// STREAM-START(utf-8) -// TAG("!!","float") -// SCALAR("3.14",double-quoted) -// STREAM-END -// -// 3. Various scalar styles: -// -// --- # Implicit empty plain scalars do not produce tokens. -// --- a plain scalar -// --- 'a single-quoted scalar' -// --- "a double-quoted scalar" -// --- |- -// a literal scalar -// --- >- -// a folded -// scalar -// -// Tokens: -// -// STREAM-START(utf-8) -// DOCUMENT-START -// DOCUMENT-START -// SCALAR("a plain scalar",plain) -// DOCUMENT-START -// SCALAR("a single-quoted scalar",single-quoted) -// DOCUMENT-START -// SCALAR("a double-quoted scalar",double-quoted) -// DOCUMENT-START -// SCALAR("a literal scalar",literal) -// DOCUMENT-START -// SCALAR("a folded scalar",folded) -// STREAM-END -// -// Now it's time to review collection-related tokens. We will start with -// flow collections: -// -// FLOW-SEQUENCE-START -// FLOW-SEQUENCE-END -// FLOW-MAPPING-START -// FLOW-MAPPING-END -// FLOW-ENTRY -// KEY -// VALUE -// -// The tokens FLOW-SEQUENCE-START, FLOW-SEQUENCE-END, FLOW-MAPPING-START, and -// FLOW-MAPPING-END represent the indicators '[', ']', '{', and '}' -// correspondingly. FLOW-ENTRY represent the ',' indicator. Finally the -// indicators '?' and ':', which are used for denoting mapping keys and values, -// are represented by the KEY and VALUE tokens. -// -// The following examples show flow collections: -// -// 1. A flow sequence: -// -// [item 1, item 2, item 3] -// -// Tokens: -// -// STREAM-START(utf-8) -// FLOW-SEQUENCE-START -// SCALAR("item 1",plain) -// FLOW-ENTRY -// SCALAR("item 2",plain) -// FLOW-ENTRY -// SCALAR("item 3",plain) -// FLOW-SEQUENCE-END -// STREAM-END -// -// 2. A flow mapping: -// -// { -// a simple key: a value, # Note that the KEY token is produced. -// ? a complex key: another value, -// } -// -// Tokens: -// -// STREAM-START(utf-8) -// FLOW-MAPPING-START -// KEY -// SCALAR("a simple key",plain) -// VALUE -// SCALAR("a value",plain) -// FLOW-ENTRY -// KEY -// SCALAR("a complex key",plain) -// VALUE -// SCALAR("another value",plain) -// FLOW-ENTRY -// FLOW-MAPPING-END -// STREAM-END -// -// A simple key is a key which is not denoted by the '?' indicator. Note that -// the Scanner still produce the KEY token whenever it encounters a simple key. -// -// For scanning block collections, the following tokens are used (note that we -// repeat KEY and VALUE here): -// -// BLOCK-SEQUENCE-START -// BLOCK-MAPPING-START -// BLOCK-END -// BLOCK-ENTRY -// KEY -// VALUE -// -// The tokens BLOCK-SEQUENCE-START and BLOCK-MAPPING-START denote indentation -// increase that precedes a block collection (cf. the INDENT token in Python). -// The token BLOCK-END denote indentation decrease that ends a block collection -// (cf. the DEDENT token in Python). However YAML has some syntax pecularities -// that makes detections of these tokens more complex. -// -// The tokens BLOCK-ENTRY, KEY, and VALUE are used to represent the indicators -// '-', '?', and ':' correspondingly. -// -// The following examples show how the tokens BLOCK-SEQUENCE-START, -// BLOCK-MAPPING-START, and BLOCK-END are emitted by the Scanner: -// -// 1. Block sequences: -// -// - item 1 -// - item 2 -// - -// - item 3.1 -// - item 3.2 -// - -// key 1: value 1 -// key 2: value 2 -// -// Tokens: -// -// STREAM-START(utf-8) -// BLOCK-SEQUENCE-START -// BLOCK-ENTRY -// SCALAR("item 1",plain) -// BLOCK-ENTRY -// SCALAR("item 2",plain) -// BLOCK-ENTRY -// BLOCK-SEQUENCE-START -// BLOCK-ENTRY -// SCALAR("item 3.1",plain) -// BLOCK-ENTRY -// SCALAR("item 3.2",plain) -// BLOCK-END -// BLOCK-ENTRY -// BLOCK-MAPPING-START -// KEY -// SCALAR("key 1",plain) -// VALUE -// SCALAR("value 1",plain) -// KEY -// SCALAR("key 2",plain) -// VALUE -// SCALAR("value 2",plain) -// BLOCK-END -// BLOCK-END -// STREAM-END -// -// 2. Block mappings: -// -// a simple key: a value # The KEY token is produced here. -// ? a complex key -// : another value -// a mapping: -// key 1: value 1 -// key 2: value 2 -// a sequence: -// - item 1 -// - item 2 -// -// Tokens: -// -// STREAM-START(utf-8) -// BLOCK-MAPPING-START -// KEY -// SCALAR("a simple key",plain) -// VALUE -// SCALAR("a value",plain) -// KEY -// SCALAR("a complex key",plain) -// VALUE -// SCALAR("another value",plain) -// KEY -// SCALAR("a mapping",plain) -// BLOCK-MAPPING-START -// KEY -// SCALAR("key 1",plain) -// VALUE -// SCALAR("value 1",plain) -// KEY -// SCALAR("key 2",plain) -// VALUE -// SCALAR("value 2",plain) -// BLOCK-END -// KEY -// SCALAR("a sequence",plain) -// VALUE -// BLOCK-SEQUENCE-START -// BLOCK-ENTRY -// SCALAR("item 1",plain) -// BLOCK-ENTRY -// SCALAR("item 2",plain) -// BLOCK-END -// BLOCK-END -// STREAM-END -// -// YAML does not always require to start a new block collection from a new -// line. If the current line contains only '-', '?', and ':' indicators, a new -// block collection may start at the current line. The following examples -// illustrate this case: -// -// 1. Collections in a sequence: -// -// - - item 1 -// - item 2 -// - key 1: value 1 -// key 2: value 2 -// - ? complex key -// : complex value -// -// Tokens: -// -// STREAM-START(utf-8) -// BLOCK-SEQUENCE-START -// BLOCK-ENTRY -// BLOCK-SEQUENCE-START -// BLOCK-ENTRY -// SCALAR("item 1",plain) -// BLOCK-ENTRY -// SCALAR("item 2",plain) -// BLOCK-END -// BLOCK-ENTRY -// BLOCK-MAPPING-START -// KEY -// SCALAR("key 1",plain) -// VALUE -// SCALAR("value 1",plain) -// KEY -// SCALAR("key 2",plain) -// VALUE -// SCALAR("value 2",plain) -// BLOCK-END -// BLOCK-ENTRY -// BLOCK-MAPPING-START -// KEY -// SCALAR("complex key") -// VALUE -// SCALAR("complex value") -// BLOCK-END -// BLOCK-END -// STREAM-END -// -// 2.
