Libraries are silent until main lets them speak. - -##### All log options are runtime-configurable. - -Still the job of `main` to expose these configurations. `main` may delegate this to, say, a configuration webhook, but does so explicitly. - -##### There is one log object per package. It is registered under its repository and package name. - -`main` activates logging for its repository and any dependency repositories it would also like to have output in its logstream. `main` also dictates at which level each subpackage logs. - -##### There is *one* output stream, and it is an `io.Writer` composed with a formatter. - -Splitting streams is probably not the job of your program, but rather, your log aggregation framework. If you must split output streams, again, `main` configures this and you can write a very simple two-output struct that satisfies io.Writer. - -Fancy colorful formatting and JSON output are beyond the scope of a basic logging framework -- they're application/log-collector dependent. These are, at best, provided as options, but more likely, provided by your application. - -##### Log objects are an interface - -An object knows best how to print itself. Log objects can collect more interesting metadata if they wish, however, because text isn't going away anytime soon, they must all be marshalable to text. The simplest log object is a string, which returns itself. If you wish to do more fancy tricks for printing your log objects, see also JSON output -- introspect and write a formatter which can handle your advanced log interface. Making strings is the only thing guaranteed. - -##### Log levels have specific meanings: - - * Critical: Unrecoverable. Must fail. - * Error: Data has been lost, a request has failed for a bad reason, or a required resource has been lost - * Warning: (Hopefully) Temporary conditions that may cause errors, but may work fine. A replica disappearing (that may reconnect) is a warning. - * Notice: Normal, but important (uncommon) log information. - * Info: Normal, working log information, everything is fine, but helpful notices for auditing or common operations. - * Debug: Everything is still fine, but even common operations may be logged, and less helpful but more quantity of notices. - * Trace: Anything goes, from logging every function call as part of a common operation, to tracing execution of a query. - diff --git a/vendor/github.com/coreos/pkg/capnslog/formatters.go b/vendor/github.com/coreos/pkg/capnslog/formatters.go deleted file mode 100644 index b305a845f..000000000 --- a/vendor/github.com/coreos/pkg/capnslog/formatters.go +++ /dev/null @@ -1,157 +0,0 @@ -// Copyright 2015 CoreOS, Inc. -// -// Licensed under the Apache License, Version 2.0 (the "License"); -// you may not use this file except in compliance with the License. -// You may obtain a copy of the License at -// -// http://www.apache.org/licenses/LICENSE-2.0 -// -// Unless required by applicable law or agreed to in writing, software -// distributed under the License is distributed on an "AS IS" BASIS, -// WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. -// See the License for the specific language governing permissions and -// limitations under the License. - -package capnslog - -import ( - "bufio" - "fmt" - "io" - "log" - "runtime" - "strings" - "time" -) - -type Formatter interface { - Format(pkg string, level LogLevel, depth int, entries ...interface{}) - Flush() -} - -func NewStringFormatter(w io.Writer) Formatter { - return &StringFormatter{ - w: bufio.NewWriter(w), - } -} - -type StringFormatter struct { - w *bufio.Writer -} - -func (s *StringFormatter) Format(pkg string, l LogLevel, i int, entries ...interface{}) { - now := time.Now().UTC() - s.w.WriteString(now.Format(time.RFC3339)) - s.w.WriteByte(' ') - writeEntries(s.w, pkg, l, i, entries...) - s.Flush() -} - -func writeEntries(w *bufio.Writer, pkg string, _ LogLevel, _ int, entries ...interface{}) { - if pkg != "" { - w.WriteString(pkg + ": ") - } - str := fmt.Sprint(entries...) - endsInNL := strings.HasSuffix(str, "\n") - w.WriteString(str) - if !endsInNL { - w.WriteString("\n") - } -} - -func (s *StringFormatter) Flush() { - s.w.Flush() -} - -func NewPrettyFormatter(w io.Writer, debug bool) Formatter { - return &PrettyFormatter{ - w: bufio.NewWriter(w), - debug: debug, - } -} - -type PrettyFormatter struct { - w *bufio.Writer - debug bool -} - -func (c *PrettyFormatter) Format(pkg string, l LogLevel, depth int, entries ...interface{}) { - now := time.Now() - ts := now.Format("2006-01-02 15:04:05") - c.w.WriteString(ts) - ms := now.Nanosecond() / 1000 - c.w.WriteString(fmt.Sprintf(".%06d", ms)) - if c.debug { - _, file, line, ok := runtime.Caller(depth) // It's always the same number of frames to the user's call. - if !ok { - file = "???" - line = 1 - } else { - slash := strings.LastIndex(file, "/") - if slash >= 0 { - file = file[slash+1:] - } - } - if line < 0 { - line = 0 // not a real line number - } - c.w.WriteString(fmt.Sprintf(" [%s:%d]", file, line)) - } - c.w.WriteString(fmt.Sprint(" ", l.Char(), " | ")) - writeEntries(c.w, pkg, l, depth, entries...) - c.Flush() -} - -func (c *PrettyFormatter) Flush() { - c.w.Flush() -} - -// LogFormatter emulates the form of the traditional built-in logger. -type LogFormatter struct { - logger *log.Logger - prefix string -} - -// NewLogFormatter is a helper to produce a new LogFormatter struct.

To do so, it introduces a few breaking changes. We've worked to keep these as minimal as possible. This guide explains the breaking changes and how you can quickly update your code. + +### `Token.Claims` is now an interface type + +The most requested feature from the 2.0 verison of this library was the ability to provide a custom type to the JSON parser for claims. This was implemented by introducing a new interface, `Claims`, to replace `map[string]interface{}`. We also included two concrete implementations of `Claims`: `MapClaims` and `StandardClaims`. + +`MapClaims` is an alias for `map[string]interface{}` with built in validation behavior. It is the default claims type when using `Parse`. The usage is unchanged except you must type cast the claims property. + +The old example for parsing a token looked like this.. + +```go + if token, err := jwt.Parse(tokenString, keyLookupFunc); err == nil { + fmt.Printf("Token for user %v expires %v", token.Claims["user"], token.Claims["exp"]) + } +``` + +is now directly mapped to... + +```go + if token, err := jwt.Parse(tokenString, keyLookupFunc); err == nil { + claims := token.Claims.(jwt.MapClaims) + fmt.Printf("Token for user %v expires %v", claims["user"], claims["exp"]) + } +``` + +`StandardClaims` is designed to be embedded in your custom type. You can supply a custom claims type with the new `ParseWithClaims` function. Here's an example of using a custom claims type. + +```go + type MyCustomClaims struct { + User string + *StandardClaims + } + + if token, err := jwt.ParseWithClaims(tokenString, &MyCustomClaims{}, keyLookupFunc); err == nil { + claims := token.Claims.(*MyCustomClaims) + fmt.Printf("Token for user %v expires %v", claims.User, claims.StandardClaims.ExpiresAt) + } +``` + +### `ParseFromRequest` has been moved + +To keep this library focused on the tokens without becoming overburdened with complex request processing logic, `ParseFromRequest` and its new companion `ParseFromRequestWithClaims` have been moved to a subpackage, `request`. The method signatues have also been augmented to receive a new argument: `Extractor`. + +`Extractors` do the work of picking the token string out of a request. The interface is simple and composable. + +This simple parsing example: + +```go + if token, err := jwt.ParseFromRequest(tokenString, req, keyLookupFunc); err == nil { + fmt.Printf("Token for user %v expires %v", token.Claims["user"], token.Claims["exp"]) + } +``` + +is directly mapped to: + +```go + if token, err := request.ParseFromRequest(req, request.OAuth2Extractor, keyLookupFunc); err == nil { + claims := token.Claims.(jwt.MapClaims) + fmt.Printf("Token for user %v expires %v", claims["user"], claims["exp"]) + } +``` + +There are several concrete `Extractor` types provided for your convenience: + +* `HeaderExtractor` will search a list of headers until one contains content. +* `ArgumentExtractor` will search a list of keys in request query and form arguments until one contains content. +* `MultiExtractor` will try a list of `Extractors` in order until one returns content. +* `AuthorizationHeaderExtractor` will look in the `Authorization` header for a `Bearer` token. +* `OAuth2Extractor` searches the places an OAuth2 token would be specified (per the spec): `Authorization` header and `access_token` argument +* `PostExtractionFilter` wraps an `Extractor`, allowing you to process the content before it's parsed. A simple example is stripping the `Bearer ` text from a header + + +### RSA signing methods no longer accept `[]byte` keys + +Due to a [critical vulnerability](https://auth0.com/blog/2015/03/31/critical-vulnerabilities-in-json-web-token-libraries/), we've decided the convenience of accepting `[]byte` instead of `rsa.PublicKey` or `rsa.PrivateKey` isn't worth the risk of misuse. + +To replace this behavior, we've added two helper methods: `ParseRSAPrivateKeyFromPEM(key []byte) (*rsa.PrivateKey, error)` and `ParseRSAPublicKeyFromPEM(key []byte) (*rsa.PublicKey, error)`. These are just simple helpers for unpacking PEM encoded PKCS1 and PKCS8 keys. If your keys are encoded any other way, all you need to do is convert them to the `crypto/rsa` package's types. + +```go + func keyLookupFunc(*Token) (interface{}, error) { + // Don't forget to validate the alg is what you expect: + if _, ok := token.Method.(*jwt.SigningMethodRSA); !ok { + return nil, fmt.Errorf("Unexpected signing method: %v", token.Header["alg"]) + } + + // Look up key + key, err := lookupPublicKey(token.Header["kid"]) + if err != nil { + return nil, err + } + + // Unpack key from PEM encoded PKCS8 + return jwt.ParseRSAPublicKeyFromPEM(key) + } +``` diff --git a/vendor/github.com/form3tech-oss/jwt-go/README.md b/vendor/github.com/form3tech-oss/jwt-go/README.md new file mode 100644 index 000000000..d7749077f --- /dev/null +++ b/vendor/github.com/form3tech-oss/jwt-go/README.md @@ -0,0 +1,104 @@ +# jwt-go + +[![Build Status](https://travis-ci.org/dgrijalva/jwt-go.svg?branch=master)](https://travis-ci.org/dgrijalva/jwt-go) +[![GoDoc](https://godoc.org/github.com/dgrijalva/jwt-go?status.svg)](https://godoc.org/github.com/dgrijalva/jwt-go) + +A [go](http://www.golang.org) (or 'golang' for search engine friendliness) implementation of [JSON Web Tokens](http://self-issued.info/docs/draft-ietf-oauth-json-web-token.html) + +**NEW VERSION COMING:** There have been a lot of improvements suggested since the version 3.0.0 released in 2016.

See the examples provided. + +## What the heck is a JWT? + +JWT.io has [a great introduction](https://jwt.io/introduction) to JSON Web Tokens. + +In short, it's a signed JSON object that does something useful (for example, authentication). It's commonly used for `Bearer` tokens in Oauth 2. A token is made of three parts, separated by `.`'s. The first two parts are JSON objects, that have been [base64url](http://tools.ietf.org/html/rfc4648) encoded. The last part is the signature, encoded the same way. + +The first part is called the header. It contains the necessary information for verifying the last part, the signature. For example, which encryption method was used for signing and what key was used. + +The part in the middle is the interesting bit. It's called the Claims and contains the actual stuff you care about. Refer to [the RFC](http://self-issued.info/docs/draft-ietf-oauth-json-web-token.html) for information about reserved keys and the proper way to add your own. + +## What's in the box? + +This library supports the parsing and verification as well as the generation and signing of JWTs. Current supported signing algorithms are HMAC SHA, RSA, RSA-PSS, and ECDSA, though hooks are present for adding your own. + +## Examples + +See [the project documentation](https://godoc.org/github.com/dgrijalva/jwt-go) for examples of usage: + +* [Simple example of parsing and validating a token](https://godoc.org/github.com/dgrijalva/jwt-go#example-Parse--Hmac) +* [Simple example of building and signing a token](https://godoc.org/github.com/dgrijalva/jwt-go#example-New--Hmac) +* [Directory of Examples](https://godoc.org/github.com/dgrijalva/jwt-go#pkg-examples) + +## Extensions + +This library publishes all the necessary components for adding your own signing methods. Simply implement the `SigningMethod` interface and register a factory method using `RegisterSigningMethod`. + +Here's an example of an extension that integrates with multiple Google Cloud Platform signing tools (AppEngine, IAM API, Cloud KMS): https://github.com/someone1/gcp-jwt-go + +## Compliance + +This library was last reviewed to comply with [RTF 7519](http://www.rfc-editor.org/info/rfc7519) dated May 2015 with a few notable differences: + +* In order to protect against accidental use of [Unsecured JWTs](http://self-issued.info/docs/draft-ietf-oauth-json-web-token.html#UnsecuredJWT), tokens using `alg=none` will only be accepted if the constant `jwt.UnsafeAllowNoneSignatureType` is provided as the key. + +## Project Status & Versioning + +This library is considered production ready. Feedback and feature requests are appreciated. The API should be considered stable. There should be very few backwards-incompatible changes outside of major version updates (and only with good reason). + +This project uses [Semantic Versioning 2.0.0](http://semver.org). Accepted pull requests will land on `master`. Periodically, versions will be tagged from `master`. You can find all the releases on [the project releases page](https://github.com/dgrijalva/jwt-go/releases). + +While we try to make it obvious when we make breaking changes, there isn't a great mechanism for pushing announcements out to users. You may want to use this alternative package include: `gopkg.in/dgrijalva/jwt-go.v3`. It will do the right thing WRT semantic versioning. + +**BREAKING CHANGES:*** +* Version 3.0.0 includes _a lot_ of changes from the 2.x line, including a few that break the API. We've tried to break as few things as possible, so there should just be a few type signature changes. A full list of breaking changes is available in `VERSION_HISTORY.md`. See `MIGRATION_GUIDE.md` for more information on updating your code. + +## Usage Tips + +### Signing vs Encryption + +A token is simply a JSON object that is signed by its author. this tells you exactly two things about the data: + +* The author of the token was in the possession of the signing secret +* The data has not been modified since it was signed + +It's important to know that JWT does not provide encryption, which means anyone who has access to the token can read its contents. If you need to protect (encrypt) the data, there is a companion spec, `JWE`, that provides this functionality. JWE is currently outside the scope of this library. + +### Choosing a Signing Method + +There are several signing methods available, and you should probably take the time to learn about the various options before choosing one. The principal design decision is most likely going to be symmetric vs asymmetric. + +Symmetric signing methods, such as HSA, use only a single secret. This is probably the simplest signing method to use since any `[]byte` can be used as a valid secret. They are also slightly computationally faster to use, though this rarely is enough to matter. Symmetric signing methods work the best when both producers and consumers of tokens are trusted, or even the same system. Since the same secret is used to both sign and validate tokens, you can't easily distribute the key for validation. + +Asymmetric signing methods, such as RSA, use different keys for signing and verifying tokens. This makes it possible to produce tokens with a private key, and allow any consumer to access the public key for verification. + +### Signing Methods and Key Types + +Each signing method expects a different object type for its signing keys. See the package documentation for details. Here are the most common ones: + +* The [HMAC signing method](https://godoc.org/github.com/dgrijalva/jwt-go#SigningMethodHMAC) (`HS256`,`HS384`,`HS512`) expect `[]byte` values for signing and validation +* The [RSA signing method](https://godoc.org/github.com/dgrijalva/jwt-go#SigningMethodRSA) (`RS256`,`RS384`,`RS512`) expect `*rsa.PrivateKey` for signing and `*rsa.PublicKey` for validation +* The [ECDSA signing method](https://godoc.org/github.com/dgrijalva/jwt-go#SigningMethodECDSA) (`ES256`,`ES384`,`ES512`) expect `*ecdsa.PrivateKey` for signing and `*ecdsa.PublicKey` for validation + +### JWT and OAuth + +It's worth mentioning that OAuth and JWT are not the same thing. A JWT token is simply a signed JSON object. It can be used anywhere such a thing is useful. There is some confusion, though, as JWT is the most common type of bearer token used in OAuth2 authentication. + +Without going too far down the rabbit hole, here's a description of the interaction of these technologies: + +* OAuth is a protocol for allowing an identity provider to be separate from the service a user is logging in to. For example, whenever you use Facebook to log into a different service (Yelp, Spotify, etc), you are using OAuth. +* OAuth defines several options for passing around authentication data. One popular method is called a "bearer token". A bearer token is simply a string that _should_ only be held by an authenticated user. Thus, simply presenting this token proves your identity. You can probably derive from here why a JWT might make a good bearer token. +* Because bearer tokens are used for authentication, it's important they're kept secret. This is why transactions that use bearer tokens typically happen over SSL. + +### Troubleshooting + +This library uses descriptive error messages whenever possible. If you are not getting the expected result, have a look at the errors. The most common place people get stuck is providing the correct type of key to the parser. See the above section on signing methods and key types. + +## More + +Documentation can be found [on godoc.org](http://godoc.org/github.com/dgrijalva/jwt-go). + +The command line utility included in this project (cmd/jwt) provides a straightforward example of token creation and parsing as well as a useful tool for debugging your own integration. You'll also find several implementation examples in the documentation. diff --git a/vendor/github.com/form3tech-oss/jwt-go/VERSION_HISTORY.md b/vendor/github.com/form3tech-oss/jwt-go/VERSION_HISTORY.md new file mode 100644 index 000000000..637029831 --- /dev/null +++ b/vendor/github.com/form3tech-oss/jwt-go/VERSION_HISTORY.md @@ -0,0 +1,118 @@ +## `jwt-go` Version History + +#### 3.2.0 + +* Added method `ParseUnverified` to allow users to split up the tasks of parsing and validation +* HMAC signing method returns `ErrInvalidKeyType` instead of `ErrInvalidKey` where appropriate +* Added options to `request.ParseFromRequest`, which allows for an arbitrary list of modifiers to parsing behavior.

The first was a refactor required to expand the width of the RSA and HMAC-SHA signing implementations. There will likely be no required code changes to support this change. + +The second update, while unfortunately requiring a small change in integration, is required to open up this library to other signing methods. Not all keys used for all signing methods have a single standard on-disk representation. Requiring `[]byte` as the type for all keys proved too limiting. Additionally, this implementation allows for pre-parsed tokens to be reused, which might matter in an application that parses a high volume of tokens with a small set of keys. Backwards compatibilty has been maintained for passing `[]byte` to the RSA signing methods, but they will also accept `*rsa.PublicKey` and `*rsa.PrivateKey`. + +It is likely the only integration change required here will be to change `func(t *jwt.Token) ([]byte, error)` to `func(t *jwt.Token) (interface{}, error)` when calling `Parse`. + +* **Compatibility Breaking Changes** + * `SigningMethodHS256` is now `*SigningMethodHMAC` instead of `type struct` + * `SigningMethodRS256` is now `*SigningMethodRSA` instead of `type struct` + * `KeyFunc` now returns `interface{}` instead of `[]byte` + * `SigningMethod.Sign` now takes `interface{}` instead of `[]byte` for the key + * `SigningMethod.Verify` now takes `interface{}` instead of `[]byte` for the key +* Renamed type `SigningMethodHS256` to `SigningMethodHMAC`.

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.

All client-side metrics start with `grpc_client`. Both of them have mirror-concepts. Similarly all methods +contain the same rich labels: + + * `grpc_service` - the [gRPC service](http://www.grpc.io/docs/#defining-a-service) name, which is the combination of protobuf `package` and + the `grpc_service` section name. E.g. for `package = mwitkow.testproto` and + `service TestService` the label will be `grpc_service="mwitkow.testproto.TestService"` + * `grpc_method` - the name of the method called on the gRPC service. E.g. + `grpc_method="Ping"` + * `grpc_type` - the gRPC [type of request](http://www.grpc.io/docs/guides/concepts.html#rpc-life-cycle). + Differentiating between the two is important especially for latency measurements. + + - `unary` is single request, single response RPC + - `client_stream` is a multi-request, single response RPC + - `server_stream` is a single request, multi-response RPC + - `bidi_stream` is a multi-request, multi-response RPC + + +Additionally for completed RPCs, the following labels are used: + + * `grpc_code` - the human-readable [gRPC status code](https://github.com/grpc/grpc-go/blob/master/codes/codes.go). + The list of all statuses is to long, but here are some common ones: + + - `OK` - means the RPC was successful + - `IllegalArgument` - RPC contained bad values + - `Internal` - server-side error not disclosed to the clients + +## Counters + +The counters and their up to date documentation is in [server_reporter.go](server_reporter.go) and [client_reporter.go](client_reporter.go) +the respective Prometheus handler (usually `/metrics`). + +For the purpose of this documentation we will only discuss `grpc_server` metrics. The `grpc_client` ones contain mirror concepts. + +For simplicity, let's assume we're tracking a single server-side RPC call of [`mwitkow.testproto.TestService`](examples/testproto/test.proto), +calling the method `PingList`. The call succeeds and returns 20 messages in the stream. + +First, immediately after the server receives the call it will increment the +`grpc_server_started_total` and start the handling time clock (if histograms are enabled). + +```jsoniq +grpc_server_started_total{grpc_method="PingList",grpc_service="mwitkow.testproto.TestService",grpc_type="server_stream"} 1 +``` + +Then the user logic gets invoked. It receives one message from the client containing the request +(it's a `server_stream`): + +```jsoniq +grpc_server_msg_received_total{grpc_method="PingList",grpc_service="mwitkow.testproto.TestService",grpc_type="server_stream"} 1 +``` + +The user logic may return an error, or send multiple messages back to the client. In this case, on +each of the 20 messages sent back, a counter will be incremented: + +```jsoniq +grpc_server_msg_sent_total{grpc_method="PingList",grpc_service="mwitkow.testproto.TestService",grpc_type="server_stream"} 20 +``` + +After the call completes, its status (`OK` or other [gRPC status code](https://github.com/grpc/grpc-go/blob/master/codes/codes.go)) +and the relevant call labels increment the `grpc_server_handled_total` counter. + +```jsoniq +grpc_server_handled_total{grpc_code="OK",grpc_method="PingList",grpc_service="mwitkow.testproto.TestService",grpc_type="server_stream"} 1 +``` + +## Histograms + +[Prometheus histograms](https://prometheus.io/docs/concepts/metric_types/#histogram) are a great way +to measure latency distributions of your RPCs. However, since it is bad practice to have metrics +of [high cardinality](https://prometheus.io/docs/practices/instrumentation/#do-not-overuse-labels) +the latency monitoring metrics are disabled by default. To enable them please call the following +in your server initialization code: + +```jsoniq +grpc_prometheus.EnableHandlingTimeHistogram() +``` + +After the call completes, its handling time will be recorded in a [Prometheus histogram](https://prometheus.io/docs/concepts/metric_types/#histogram) +variable `grpc_server_handling_seconds`. The histogram variable contains three sub-metrics: + + * `grpc_server_handling_seconds_count` - the count of all completed RPCs by status and method + * `grpc_server_handling_seconds_sum` - cumulative time of RPCs by status and method, useful for + calculating average handling times + * `grpc_server_handling_seconds_bucket` - contains the counts of RPCs by status and method in respective + handling-time buckets. These buckets can be used by Prometheus to estimate SLAs (see [here](https://prometheus.io/docs/practices/histograms/)) + +The counter values will look as follows: + +```jsoniq +grpc_server_handling_seconds_bucket{grpc_code="OK",grpc_method="PingList",grpc_service="mwitkow.testproto.TestService",grpc_type="server_stream",le="0.005"} 1 +grpc_server_handling_seconds_bucket{grpc_code="OK",grpc_method="PingList",grpc_service="mwitkow.testproto.TestService",grpc_type="server_stream",le="0.01"} 1 +grpc_server_handling_seconds_bucket{grpc_code="OK",grpc_method="PingList",grpc_service="mwitkow.testproto.TestService",grpc_type="server_stream",le="0.025"} 1 +grpc_server_handling_seconds_bucket{grpc_code="OK",grpc_method="PingList",grpc_service="mwitkow.testproto.TestService",grpc_type="server_stream",le="0.05"} 1 +grpc_server_handling_seconds_bucket{grpc_code="OK",grpc_method="PingList",grpc_service="mwitkow.testproto.TestService",grpc_type="server_stream",le="0.1"} 1 +grpc_server_handling_seconds_bucket{grpc_code="OK",grpc_method="PingList",grpc_service="mwitkow.testproto.TestService",grpc_type="server_stream",le="0.25"} 1 +grpc_server_handling_seconds_bucket{grpc_code="OK",grpc_method="PingList",grpc_service="mwitkow.testproto.TestService",grpc_type="server_stream",le="0.5"} 1 +grpc_server_handling_seconds_bucket{grpc_code="OK",grpc_method="PingList",grpc_service="mwitkow.testproto.TestService",grpc_type="server_stream",le="1"} 1 +grpc_server_handling_seconds_bucket{grpc_code="OK",grpc_method="PingList",grpc_service="mwitkow.testproto.TestService",grpc_type="server_stream",le="2.5"} 1 +grpc_server_handling_seconds_bucket{grpc_code="OK",grpc_method="PingList",grpc_service="mwitkow.testproto.TestService",grpc_type="server_stream",le="5"} 1 +grpc_server_handling_seconds_bucket{grpc_code="OK",grpc_method="PingList",grpc_service="mwitkow.testproto.TestService",grpc_type="server_stream",le="10"} 1 +grpc_server_handling_seconds_bucket{grpc_code="OK",grpc_method="PingList",grpc_service="mwitkow.testproto.TestService",grpc_type="server_stream",le="+Inf"} 1 +grpc_server_handling_seconds_sum{grpc_code="OK",grpc_method="PingList",grpc_service="mwitkow.testproto.TestService",grpc_type="server_stream"} 0.0003866430000000001 +grpc_server_handling_seconds_count{grpc_code="OK",grpc_method="PingList",grpc_service="mwitkow.testproto.TestService",grpc_type="server_stream"} 1 +``` + + +## Useful query examples + +Prometheus philosophy is to provide raw metrics to the monitoring system, and +let the aggregations be handled there. The verbosity of above metrics make it possible to have that +flexibility. Here's a couple of useful monitoring queries: + + +### request inbound rate +```jsoniq +sum(rate(grpc_server_started_total{job="foo"}[1m])) by (grpc_service) +``` +For `job="foo"` (common label to differentiate between Prometheus monitoring targets), calculate the +rate of requests per second (1 minute window) for each gRPC `grpc_service` that the job has.

Furthermore, if you are not concerned with +// fine-grained control of when and how to register metrics with the registry, +// have a look at the promauto package, which will effectively allow you to +// ignore registration altogether in simple cases. +// +// Above, you have already touched the Counter and the Gauge. There are two more +// advanced metric types: the Summary and Histogram. A more thorough description +// of those four metric types can be found in the Prometheus docs: +// https://prometheus.io/docs/concepts/metric_types/ +// +// In addition to the fundamental metric types Gauge, Counter, Summary, and +// Histogram, a very important part of the Prometheus data model is the +// partitioning of samples along dimensions called labels, which results in +// metric vectors. The fundamental types are GaugeVec, CounterVec, SummaryVec, +// and HistogramVec. +// +// While only the fundamental metric types implement the Metric interface, both +// the metrics and their vector versions implement the Collector interface. A +// Collector manages the collection of a number of Metrics, but for convenience, +// a Metric can also “collect itself”. Note that Gauge, Counter, Summary, and +// Histogram are interfaces themselves while GaugeVec, CounterVec, SummaryVec, +// and HistogramVec are not. +// +// To create instances of Metrics and their vector versions, you need a suitable +// …Opts struct, i.e. GaugeOpts, CounterOpts, SummaryOpts, or HistogramOpts. +// +// Custom Collectors and constant Metrics +// +// While you could create your own implementations of Metric, most likely you +// will only ever implement the Collector interface on your own. At a first +// glance, a custom Collector seems handy to bundle Metrics for common +// registration (with the prime example of the different metric vectors above, +// which bundle all the metrics of the same name but with different labels). +// +// There is a more involved use case, too: If you already have metrics +// available, created outside of the Prometheus context, you don't need the +// interface of the various Metric types. You essentially want to mirror the +// existing numbers into Prometheus Metrics during collection. An own +// implementation of the Collector interface is perfect for that. You can create +// Metric instances “on the fly” using NewConstMetric, NewConstHistogram, and +// NewConstSummary (and their respective Must… versions). NewConstMetric is used +// for all metric types with just a float64 as their value: Counter, Gauge, and +// a special “type” called Untyped. Use the latter if you are not sure if the +// mirrored metric is a Counter or a Gauge. Creation of the Metric instance +// happens in the Collect method. The Describe method has to return separate +// Desc instances, representative of the “throw-away” metrics to be created +// later. NewDesc comes in handy to create those Desc instances. Alternatively, +// you could return no Desc at all, which will mark the Collector “unchecked”. +// No checks are performed at registration time, but metric consistency will +// still be ensured at scrape time, i.e. any inconsistencies will lead to scrape +// errors. Thus, with unchecked Collectors, the responsibility to not collect +// metrics that lead to inconsistencies in the total scrape result lies with the +// implementer of the Collector. While this is not a desirable state, it is +// sometimes necessary. The typical use case is a situation where the exact +// metrics to be returned by a Collector cannot be predicted at registration +// time, but the implementer has sufficient knowledge of the whole system to +// guarantee metric consistency. +// +// The Collector example illustrates the use case. You can also look at the +// source code of the processCollector (mirroring process metrics), the +// goCollector (mirroring Go metrics), or the expvarCollector (mirroring expvar +// metrics) as examples that are used in this package itself. +// +// If you just need to call a function to get a single float value to collect as +// a metric, GaugeFunc, CounterFunc, or UntypedFunc might be interesting +// shortcuts. +// +// Advanced Uses of the Registry +// +// While MustRegister is the by far most common way of registering a Collector, +// sometimes you might want to handle the errors the registration might cause. +// As suggested by the name, MustRegister panics if an error occurs. With the +// Register function, the error is returned and can be handled. +// +// An error is returned if the registered Collector is incompatible or +// inconsistent with already registered metrics. The registry aims for +// consistency of the collected metrics according to the Prometheus data model. +// Inconsistencies are ideally detected at registration time, not at collect +// time. The former will usually be detected at start-up time of a program, +// while the latter will only happen at scrape time, possibly not even on the +// first scrape if the inconsistency only becomes relevant later. That is the +// main reason why a Collector and a Metric have to describe themselves to the +// registry. +// +// So far, everything we did operated on the so-called default registry, as it +// can be found in the global DefaultRegisterer variable. With NewRegistry, you +// can create a custom registry, or you can even implement the Registerer or +// Gatherer interfaces yourself. The methods Register and Unregister work in the +// same way on a custom registry as the global functions Register and Unregister +// on the default registry. +// +// There are a number of uses for custom registries: You can use registries with +// special properties, see NewPedanticRegistry. You can avoid global state, as +// it is imposed by the DefaultRegisterer. You can use multiple registries at +// the same time to expose different metrics in different ways. You can use +// separate registries for testing purposes. +// +// Also note that the DefaultRegisterer comes registered with a Collector for Go +// runtime metrics (via NewGoCollector) and a Collector for process metrics (via +// NewProcessCollector). With a custom registry, you are in control and decide +// yourself about the Collectors to register. +// +// HTTP Exposition +// +// The Registry implements the Gatherer interface. The caller of the Gather +// method can then expose the gathered metrics in some way. Usually, the metrics +// are served via HTTP on the /metrics endpoint. That's happening in the example +// above. The tools to expose metrics via HTTP are in the promhttp sub-package. +// +// Pushing to the Pushgateway +// +// Function for pushing to the Pushgateway can be found in the push sub-package. +// +// Graphite Bridge +// +// Functions and examples to push metrics from a Gatherer to Graphite can be +// found in the graphite sub-package. +// +// Other Means of Exposition +// +// More ways of exposing metrics can easily be added by following the approaches +// of the existing implementations. +package prometheus diff --git a/vendor/github.com/prometheus/client_golang/prometheus/expvar_collector.go b/vendor/github.com/prometheus/client_golang/prometheus/expvar_collector.go new file mode 100644 index 000000000..c41ab37f3 --- /dev/null +++ b/vendor/github.com/prometheus/client_golang/prometheus/expvar_collector.go @@ -0,0 +1,86 @@ +// Copyright 2014 The Prometheus Authors +// Licensed under the Apache License, Version 2.0 (the "License");

This requires a working Go environment with version 1.12 or greater installed. + +All dependencies are vendored in the `vendor/` directory. + +To add or update a new dependency, use the `go get` command: + +```bash +# Pick the latest tagged release. +go get example.com/some/module/pkg + +# Pick a specific version. +go get example.com/some/module/pkg@vX.Y.Z +``` + +Tidy up the `go.mod` and `go.sum` files and copy the new/updated dependency to the `vendor/` directory: + + +```bash +# The GO111MODULE variable can be omitted when the code isn't located in GOPATH. +GO111MODULE=on go mod tidy + +GO111MODULE=on go mod vendor +``` + +You have to commit the changes to `go.mod`, `go.sum` and the `vendor/` directory before submitting the pull request. + + +## API Implementation Guidelines + +### Naming and Documentation + +Public functions and structs should normally be named according to the file(s) being read and parsed. For example, +the `fs.BuddyInfo()` function reads the file `/proc/buddyinfo`. In addition, the godoc for each public function +should contain the path to the file(s) being read and a URL of the linux kernel documentation describing the file(s). + +### Reading vs. Parsing + +Most functionality in this library consists of reading files and then parsing the text into structured data. In most +cases reading and parsing should be separated into different functions/methods with a public `fs.Thing()` method and +a private `parseThing(r Reader)` function. This provides a logical separation and allows parsing to be tested +directly without the need to read from the filesystem. Using a `Reader` argument is preferred over other data types +such as `string` or `*File` because it provides the most flexibility regarding the data source. When a set of files +in a directory needs to be parsed, then a `path` string parameter to the parse function can be used instead. + +### /proc and /sys filesystem I/O + +The `proc` and `sys` filesystems are pseudo file systems and work a bit differently from standard disk I/O. +Many of the files are changing continuously and the data being read can in some cases change between subsequent +reads in the same file. Also, most of the files are relatively small (less than a few KBs), and system calls +to the `stat` function will often return the wrong size. Therefore, for most files it's recommended to read the +full file in a single operation using an internal utility function called `util.ReadFileNoStat`. +This function is similar to `ioutil.ReadFile`, but it avoids the system call to `stat` to get the current size of +the file. + +Note that parsing the file's contents can still be performed one line at a time. This is done by first reading +the full file, and then using a scanner on the `[]byte` or `string` containing the data. + +``` + data, err := util.ReadFileNoStat("/proc/cpuinfo") + if err != nil { + return err + } + reader := bytes.NewReader(data) + scanner := bufio.NewScanner(reader) +``` + +The `/sys` filesystem contains many very small files which contain only a single numeric or text value. These files +can be read using an internal function called `util.SysReadFile` which is similar to `ioutil.ReadFile` but does +not bother to check the size of the file before reading. +``` + data, err := util.SysReadFile("/sys/class/power_supply/BAT0/capacity") +``` + diff --git a/vendor/github.com/prometheus/procfs/LICENSE b/vendor/github.com/prometheus/procfs/LICENSE new file mode 100644 index 000000000..261eeb9e9 --- /dev/null +++ b/vendor/github.com/prometheus/procfs/LICENSE @@ -0,0 +1,201 @@ + Apache License + Version 2.0, January 2004 + http://www.apache.org/licenses/ + + TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION + + 1.

Each package contains an `FS` type which represents the path to either /proc, +/sys, or both. For example, cpu statistics are gathered from +`/proc/stat` and are available via the root procfs package. First, the proc filesystem mount +point is initialized, and then the stat information is read. + +```go +fs, err := procfs.NewFS("/proc") +stats, err := fs.Stat() +``` + +Some sub-packages such as `blockdevice`, require access to both the proc and sys filesystems. + +```go + fs, err := blockdevice.NewFS("/proc", "/sys") + stats, err := fs.ProcDiskstats() +``` + +## Package Organization + +The packages in this project are organized according to (1) whether the data comes from the `/proc` or +`/sys` filesystem and (2) the type of information being retrieved. For example, most process information +can be gathered from the functions in the root `procfs` package. Information about block devices such as disk drives +is available in the `blockdevices` sub-package. + +## Building and Testing + +The procfs library is intended to be built as part of another application, so there are no distributable binaries. +However, most of the API includes unit tests which can be run with `make test`. + +### Updating Test Fixtures + +The procfs library includes a set of test fixtures which include many example files from +the `/proc` and `/sys` filesystems. These fixtures are included as a [ttar](https://github.com/ideaship/ttar) file +which is extracted automatically during testing. To add/update the test fixtures, first +ensure the `fixtures` directory is up to date by removing the existing directory and then +extracting the ttar file using `make fixtures/.unpacked` or just `make test`. + +```bash +rm -rf fixtures +make test +``` + +Next, make the required changes to the extracted files in the `fixtures` directory. When +the changes are complete, run `make update_fixtures` to create a new `fixtures.ttar` file +based on the updated `fixtures` directory. And finally, verify the changes using +`git diff fixtures.ttar`. diff --git a/vendor/github.com/prometheus/procfs/SECURITY.md b/vendor/github.com/prometheus/procfs/SECURITY.md new file mode

Using cmux, you can serve gRPC, SSH, HTTPS, HTTP, +Go RPC, and pretty much any other protocol on the same TCP listener. + +## How-To +Simply create your main listener, create a cmux for that listener, +and then match connections: +```go +// Create the main listener. +l, err := net.Listen("tcp", ":23456") +if err != nil { + log.Fatal(err) +} + +// Create a cmux. +m := cmux.New(l) + +// Match connections in order: +// First grpc, then HTTP, and otherwise Go RPC/TCP. +grpcL := m.Match(cmux.HTTP2HeaderField("content-type", "application/grpc")) +httpL := m.Match(cmux.HTTP1Fast()) +trpcL := m.Match(cmux.Any()) // Any means anything that is not yet matched. + +// Create your protocol servers. +grpcS := grpc.NewServer() +grpchello.RegisterGreeterServer(grpcS, &server{}) + +httpS := &http.Server{ + Handler: &helloHTTP1Handler{}, +} + +trpcS := rpc.NewServer() +trpcS.Register(&ExampleRPCRcvr{}) + +// Use the muxed listeners for your servers. +go grpcS.Serve(grpcL) +go httpS.Serve(httpL) +go trpcS.Accept(trpcL) + +// Start serving! +m.Serve() +``` + +Take a look at [other examples in the GoDoc](http://godoc.org/github.com/soheilhy/cmux/#pkg-examples). + +## Docs +* [GoDocs](https://godoc.org/github.com/soheilhy/cmux) + +## Performance +There is room for improvment but, since we are only matching +the very first bytes of a connection, the performance overheads on +long-lived connections (i.e., RPCs and pipelined HTTP streams) +is negligible. + +*TODO(soheil)*: Add benchmarks. + +## Limitations +* *TLS*: `net/http` uses a type assertion to identify TLS connections; since +cmux's lookahead-implementing connection wraps the underlying TLS connection, +this type assertion fails. +Because of that, you can serve HTTPS using cmux but `http.Request.TLS` +would not be set in your handlers. + +* *Different Protocols on The Same Connection*: `cmux` matches the connection +when it's accepted. For example, one connection can be either gRPC or REST, but +not both. That is, we assume that a client connection is either used for gRPC +or REST. + +* *Java gRPC Clients*: Java gRPC client blocks until it receives a SETTINGS +frame from the server. If you are using the Java client to connect to a cmux'ed +gRPC server please match with writers: +```go +grpcl := m.MatchWithWriters(cmux.HTTP2MatchHeaderFieldSendSettings("content-type", "application/grpc")) +``` + +# Copyright and License +Copyright 2016 The CMux Authors.

It is represented as a single file on +your disk and represents a consistent snapshot of your data. + +To open your database, simply use the `bolt.Open()` function: + +```go +package main + +import ( + "log" + + bolt "go.etcd.io/bbolt" +) + +func main() { + // Open the my.db data file in your current directory. + // It will be created if it doesn't exist. + db, err := bolt.Open("my.db", 0600, nil) + if err != nil { + log.Fatal(err) + } + defer db.Close() + + ... +} +``` + +Please note that Bolt obtains a file lock on the data file so multiple processes +cannot open the same database at the same time. Opening an already open Bolt +database will cause it to hang until the other process closes it. To prevent +an indefinite wait you can pass a timeout option to the `Open()` function: + +```go +db, err := bolt.Open("my.db", 0600, &bolt.Options{Timeout: 1 * time.Second}) +``` + + +### Transactions + +Bolt allows only one read-write transaction at a time but allows as many +read-only transactions as you want at a time. Each transaction has a consistent +view of the data as it existed when the transaction started. + +Individual transactions and all objects created from them (e.g. buckets, keys) +are not thread safe. To work with data in multiple goroutines you must start +a transaction for each one or use locking to ensure only one goroutine accesses +a transaction at a time. Creating transaction from the `DB` is thread safe. + +Transactions should not depend on one another and generally shouldn't be opened +simultaneously in the same goroutine. This can cause a deadlock as the read-write +transaction needs to periodically re-map the data file but it cannot do so while +any read-only transaction is open. Even a nested read-only transaction can cause +a deadlock, as the child transaction can block the parent transaction from releasing +its resources. + +#### Read-write transactions + +To start a read-write transaction, you can use the `DB.Update()` function: + +```go +err := db.Update(func(tx *bolt.Tx) error { + ... + return nil +}) +``` + +Inside the closure, you have a consistent view of the database. You commit the +transaction by returning `nil` at the end. You can also rollback the transaction +at any point by returning an error. All database operations are allowed inside +a read-write transaction. + +Always check the return error as it will report any disk failures that can cause +your transaction to not complete. If you return an error within your closure +it will be passed through. + + +#### Read-only transactions + +To start a read-only transaction, you can use the `DB.View()` function: + +```go +err := db.View(func(tx *bolt.Tx) error { + ... + return nil +}) +``` + +You also get a consistent view of the database within this closure, however, +no mutating operations are allowed within a read-only transaction. You can only +retrieve buckets, retrieve values, and copy the database within a read-only +transaction. + + +#### Batch read-write transactions + +Each `DB.Update()` waits for disk to commit the writes. This overhead +can be minimized by combining multiple updates with the `DB.Batch()` +function: + +```go +err := db.Batch(func(tx *bolt.Tx) error { + ... + return nil +}) +``` + +Concurrent Batch calls are opportunistically combined into larger +transactions. Batch is only useful when there are multiple goroutines +calling it. + +The trade-off is that `Batch` can call the given +function multiple times, if parts of the transaction fail. The +function must be idempotent and side effects must take effect only +after a successful return from `DB.Batch()`. + +For example: don't display messages from inside the function, instead +set variables in the enclosing scope: + +```go +var id uint64 +err := db.Batch(func(tx *bolt.Tx) error { + // Find last key in bucket, decode as bigendian uint64, increment + // by one, encode back to []byte, and add new key. + ... + id = newValue + return nil +}) +if err != nil { + return ... +} +fmt.Println("Allocated ID %d", id) +``` + + +#### Managing transactions manually + +The `DB.View()` and `DB.Update()` functions are wrappers around the `DB.Begin()` +function. These helper functions will start the transaction, execute a function, +and then safely close your transaction if an error is returned. This is the +recommended way to use Bolt transactions. + +However, sometimes you may want to manually start and end your transactions. +You can use the `DB.Begin()` function directly but **please** be sure to close +the transaction. + +```go +// Start a writable transaction. +tx, err := db.Begin(true) +if err != nil { + return err +} +defer tx.Rollback() + +// Use the transaction... +_, err := tx.CreateBucket([]byte("MyBucket")) +if err != nil { + return err +} + +// Commit the transaction and check for error. +if err := tx.Commit(); err != nil { + return err +} +``` + +The first argument to `DB.Begin()` is a boolean stating if the transaction +should be writable. + + +### Using buckets + +Buckets are collections of key/value pairs within the database. All keys in a +bucket must be unique. You can create a bucket using the `Tx.CreateBucket()` +function: + +```go +db.Update(func(tx *bolt.Tx) error { + b, err := tx.CreateBucket([]byte("MyBucket")) + if err != nil { + return fmt.Errorf("create bucket: %s", err) + } + return nil +}) +``` + +You can also create a bucket only if it doesn't exist by using the +`Tx.CreateBucketIfNotExists()` function. It's a common pattern to call this +function for all your top-level buckets after you open your database so you can +guarantee that they exist for future transactions. + +To delete a bucket, simply call the `Tx.DeleteBucket()` function. + + +### Using key/value pairs + +To save a key/value pair to a bucket, use the `Bucket.Put()` function: + +```go +db.Update(func(tx *bolt.Tx) error { + b := tx.Bucket([]byte("MyBucket")) + err := b.Put([]byte("answer"), []byte("42")) + return err +}) +``` + +This will set the value of the `"answer"` key to `"42"` in the `MyBucket` +bucket. To retrieve this value, we can use the `Bucket.Get()` function: + +```go +db.View(func(tx *bolt.Tx) error { + b := tx.Bucket([]byte("MyBucket")) + v := b.Get([]byte("answer")) + fmt.Printf("The answer is: %s\n", v) + return nil +}) +``` + +The `Get()` function does not return an error because its operation is +guaranteed to work (unless there is some kind of system failure). If the key +exists then it will return its byte slice value. If it doesn't exist then it +will return `nil`. It's important to note that you can have a zero-length value +set to a key which is different than the key not existing. + +Use the `Bucket.Delete()` function to delete a key from the bucket. + +Please note that values returned from `Get()` are only valid while the +transaction is open. If you need to use a value outside of the transaction +then you must use `copy()` to copy it to another byte slice. + + +### Autoincrementing integer for the bucket +By using the `NextSequence()` function, you can let Bolt determine a sequence +which can be used as the unique identifier for your key/value pairs. See the +example below. + +```go +// CreateUser saves u to the store. The new user ID is set on u once the data is persisted. +func (s *Store) CreateUser(u *User) error { + return s.db.Update(func(tx *bolt.Tx) error { + // Retrieve the users bucket. + // This should be created when the DB is first opened. + b := tx.Bucket([]byte("users")) + + // Generate ID for the user. + // This returns an error only if the Tx is closed or not writeable. + // That can't happen in an Update() call so I ignore the error check. + id, _ := b.NextSequence() + u.ID = int(id) + + // Marshal user data into bytes. + buf, err := json.Marshal(u) + if err != nil { + return err + } + + // Persist bytes to users bucket. + return b.Put(itob(u.ID), buf) + }) +} + +// itob returns an 8-byte big endian representation of v. +func itob(v int) []byte { + b := make([]byte, 8) + binary.BigEndian.PutUint64(b, uint64(v)) + return b +} + +type User struct { + ID int + ... +} +``` + +### Iterating over keys + +Bolt stores its keys in byte-sorted order within a bucket. This makes sequential +iteration over these keys extremely fast. To iterate over keys we'll use a +`Cursor`: + +```go +db.View(func(tx *bolt.Tx) error { + // Assume bucket exists and has keys + b := tx.Bucket([]byte("MyBucket")) + + c := b.Cursor() + + for k, v := c.First(); k != nil; k, v = c.Next() { + fmt.Printf("key=%s, value=%s\n", k, v) + } + + return nil +}) +``` + +The cursor allows you to move to a specific point in the list of keys and move +forward or backward through the keys one at a time. + +The following functions are available on the cursor: + +``` +First() Move to the first key. +Last() Move to the last key. +Seek() Move to a specific key. +Next() Move to the next key. +Prev() Move to the previous key. +``` + +Each of those functions has a return signature of `(key []byte, value []byte)`. +When you have iterated to the end of the cursor then `Next()` will return a +`nil` key. You must seek to a position using `First()`, `Last()`, or `Seek()` +before calling `Next()` or `Prev()`. If you do not seek to a position then +these functions will return a `nil` key. + +During iteration, if the key is non-`nil` but the value is `nil`, that means +the key refers to a bucket rather than a value. Use `Bucket.Bucket()` to +access the sub-bucket. + + +#### Prefix scans + +To iterate over a key prefix, you can combine `Seek()` and `bytes.HasPrefix()`: + +```go +db.View(func(tx *bolt.Tx) error { + // Assume bucket exists and has keys + c := tx.Bucket([]byte("MyBucket")).Cursor() + + prefix := []byte("1234") + for k, v := c.Seek(prefix); k != nil && bytes.HasPrefix(k, prefix); k, v = c.Next() { + fmt.Printf("key=%s, value=%s\n", k, v) + } + + return nil +}) +``` + +#### Range scans + +Another common use case is scanning over a range such as a time range. If you +use a sortable time encoding such as RFC3339 then you can query a specific +date range like this: + +```go +db.View(func(tx *bolt.Tx) error { + // Assume our events bucket exists and has RFC3339 encoded time keys. + c := tx.Bucket([]byte("Events")).Cursor() + + // Our time range spans the 90's decade. + min := []byte("1990-01-01T00:00:00Z") + max := []byte("2000-01-01T00:00:00Z") + + // Iterate over the 90's. + for k, v := c.Seek(min); k != nil && bytes.Compare(k, max) <= 0; k, v = c.Next() { + fmt.Printf("%s: %s\n", k, v) + } + + return nil +}) +``` + +Note that, while RFC3339 is sortable, the Golang implementation of RFC3339Nano does not use a fixed number of digits after the decimal point and is therefore not sortable. + + +#### ForEach() + +You can also use the function `ForEach()` if you know you'll be iterating over +all the keys in a bucket: + +```go +db.View(func(tx *bolt.Tx) error { + // Assume bucket exists and has keys + b := tx.Bucket([]byte("MyBucket")) + + b.ForEach(func(k, v []byte) error { + fmt.Printf("key=%s, value=%s\n", k, v) + return nil + }) + return nil +}) +``` + +Please note that keys and values in `ForEach()` are only valid while +the transaction is open. If you need to use a key or value outside of +the transaction, you must use `copy()` to copy it to another byte +slice. + +### Nested buckets + +You can also store a bucket in a key to create nested buckets. The API is the +same as the bucket management API on the `DB` object: + +```go +func (*Bucket) CreateBucket(key []byte) (*Bucket, error) +func (*Bucket) CreateBucketIfNotExists(key []byte) (*Bucket, error) +func (*Bucket) DeleteBucket(key []byte) error +``` + +Say you had a multi-tenant application where the root level bucket was the account bucket. Inside of this bucket was a sequence of accounts which themselves are buckets. And inside the sequence bucket you could have many buckets pertaining to the Account itself (Users, Notes, etc) isolating the information into logical groupings. + +```go + +// createUser creates a new user in the given account. +func createUser(accountID int, u *User) error { + // Start the transaction. + tx, err := db.Begin(true) + if err != nil { + return err + } + defer tx.Rollback() + + // Retrieve the root bucket for the account. + // Assume this has already been created when the account was set up. + root := tx.Bucket([]byte(strconv.FormatUint(accountID, 10))) + + // Setup the users bucket. + bkt, err := root.CreateBucketIfNotExists([]byte("USERS")) + if err != nil { + return err + } + + // Generate an ID for the new user. + userID, err := bkt.NextSequence() + if err != nil { + return err + } + u.ID = userID + + // Marshal and save the encoded user. + if buf, err := json.Marshal(u); err != nil { + return err + } else if err := bkt.Put([]byte(strconv.FormatUint(u.ID, 10)), buf); err != nil { + return err + } + + // Commit the transaction. + if err := tx.Commit(); err != nil { + return err + } + + return nil +} + +``` + + + + +### Database backups + +Bolt is a single file so it's easy to backup. You can use the `Tx.WriteTo()` +function to write a consistent view of the database to a writer. If you call +this from a read-only transaction, it will perform a hot backup and not block +your other database reads and writes. + +By default, it will use a regular file handle which will utilize the operating +system's page cache. See the [`Tx`](https://godoc.org/go.etcd.io/bbolt#Tx) +documentation for information about optimizing for larger-than-RAM datasets. + +One common use case is to backup over HTTP so you can use tools like `cURL` to +do database backups: + +```go +func BackupHandleFunc(w http.ResponseWriter, req *http.Request) { + err := db.View(func(tx *bolt.Tx) error { + w.Header().Set("Content-Type", "application/octet-stream") + w.Header().Set("Content-Disposition", `attachment; filename="my.db"`) + w.Header().Set("Content-Length", strconv.Itoa(int(tx.Size()))) + _, err := tx.WriteTo(w) + return err + }) + if err != nil { + http.Error(w, err.Error(), http.StatusInternalServerError) + } +} +``` + +Then you can backup using this command: + +```sh +$ curl http://localhost/backup > my.db +``` + +Or you can open your browser to `http://localhost/backup` and it will download +automatically. + +If you want to backup to another file you can use the `Tx.CopyFile()` helper +function. + + +### Statistics + +The database keeps a running count of many of the internal operations it +performs so you can better understand what's going on. By grabbing a snapshot +of these stats at two points in time we can see what operations were performed +in that time range. + +For example, we could start a goroutine to log stats every 10 seconds: + +```go +go func() { + // Grab the initial stats. + prev := db.Stats() + + for { + // Wait for 10s. + time.Sleep(10 * time.Second) + + // Grab the current stats and diff them. + stats := db.Stats() + diff := stats.Sub(&prev) + + // Encode stats to JSON and print to STDERR. + json.NewEncoder(os.Stderr).Encode(diff) + + // Save stats for the next loop. + prev = stats + } +}() +``` + +It's also useful to pipe these stats to a service such as statsd for monitoring +or to provide an HTTP endpoint that will perform a fixed-length sample. + + +### Read-Only Mode + +Sometimes it is useful to create a shared, read-only Bolt database. To this, +set the `Options.ReadOnly` flag when opening your database.

This approach provides flexibility in how you store and query +your data but also incurs overhead in parsing and planning SQL statements. Bolt +accesses all data by a byte slice key. This makes Bolt fast to read and write +data by key but provides no built-in support for joining values together. + +Most relational databases (with the exception of SQLite) are standalone servers +that run separately from your application. This gives your systems +flexibility to connect multiple application servers to a single database +server but also adds overhead in serializing and transporting data over the +network. Bolt runs as a library included in your application so all data access +has to go through your application's process. This brings data closer to your +application but limits multi-process access to the data. + + +### LevelDB, RocksDB + +LevelDB and its derivatives (RocksDB, HyperLevelDB) are similar to Bolt in that +they are libraries bundled into the application, however, their underlying +structure is a log-structured merge-tree (LSM tree). An LSM tree optimizes +random writes by using a write ahead log and multi-tiered, sorted files called +SSTables. Bolt uses a B+tree internally and only a single file. Both approaches +have trade-offs. + +If you require a high random write throughput (>10,000 w/sec) or you need to use +spinning disks then LevelDB could be a good choice. If your application is +read-heavy or does a lot of range scans then Bolt could be a good choice. + +One other important consideration is that LevelDB does not have transactions. +It supports batch writing of key/values pairs and it supports read snapshots +but it will not give you the ability to do a compare-and-swap operation safely. +Bolt supports fully serializable ACID transactions. + + +### LMDB + +Bolt was originally a port of LMDB so it is architecturally similar. Both use +a B+tree, have ACID semantics with fully serializable transactions, and support +lock-free MVCC using a single writer and multiple readers. + +The two projects have somewhat diverged. LMDB heavily focuses on raw performance +while Bolt has focused on simplicity and ease of use. For example, LMDB allows +several unsafe actions such as direct writes for the sake of performance. Bolt +opts to disallow actions which can leave the database in a corrupted state. The +only exception to this in Bolt is `DB.NoSync`. + +There are also a few differences in API. LMDB requires a maximum mmap size when +opening an `mdb_env` whereas Bolt will handle incremental mmap resizing +automatically. LMDB overloads the getter and setter functions with multiple +flags whereas Bolt splits these specialized cases into their own functions. + + +## Caveats & Limitations + +It's important to pick the right tool for the job and Bolt is no exception. +Here are a few things to note when evaluating and using Bolt: + +* Bolt is good for read intensive workloads. Sequential write performance is + also fast but random writes can be slow. You can use `DB.Batch()` or add a + write-ahead log to help mitigate this issue. + +* Bolt uses a B+tree internally so there can be a lot of random page access. + SSDs provide a significant performance boost over spinning disks. + +* Try to avoid long running read transactions. Bolt uses copy-on-write so + old pages cannot be reclaimed while an old transaction is using them. + +* Byte slices returned from Bolt are only valid during a transaction. Once the + transaction has been committed or rolled back then the memory they point to + can be reused by a new page or can be unmapped from virtual memory and you'll + see an `unexpected fault address` panic when accessing it. + +* Bolt uses an exclusive write lock on the database file so it cannot be + shared by multiple processes. + +* Be careful when using `Bucket.FillPercent`. Setting a high fill percent for + buckets that have random inserts will cause your database to have very poor + page utilization. + +* Use larger buckets in general. Smaller buckets causes poor page utilization + once they become larger than the page size (typically 4KB). + +* Bulk loading a lot of random writes into a new bucket can be slow as the + page will not split until the transaction is committed. Randomly inserting + more than 100,000 key/value pairs into a single new bucket in a single + transaction is not advised. + +* Bolt uses a memory-mapped file so the underlying operating system handles the + caching of the data. Typically, the OS will cache as much of the file as it + can in memory and will release memory as needed to other processes. This means + that Bolt can show very high memory usage when working with large databases. + However, this is expected and the OS will release memory as needed. Bolt can + handle databases much larger than the available physical RAM, provided its + memory-map fits in the process virtual address space. It may be problematic + on 32-bits systems. + +* The data structures in the Bolt database are memory mapped so the data file + will be endian specific. This means that you cannot copy a Bolt file from a + little endian machine to a big endian machine and have it work. For most + users this is not a concern since most modern CPUs are little endian. + +* Because of the way pages are laid out on disk, Bolt cannot truncate data files + and return free pages back to the disk. Instead, Bolt maintains a free list + of unused pages within its data file. These free pages can be reused by later + transactions. This works well for many use cases as databases generally tend + to grow. However, it's important to note that deleting large chunks of data + will not allow you to reclaim that space on disk. + + For more information on page allocation, [see this comment][page-allocation]. + +[page-allocation]: https://github.com/boltdb/bolt/issues/308#issuecomment-74811638 + + +## Reading the Source + +Bolt is a relatively small code base (<5KLOC) for an embedded, serializable, +transactional key/value database so it can be a good starting point for people +interested in how databases work. + +The best places to start are the main entry points into Bolt: + +- `Open()` - Initializes the reference to the database. It's responsible for + creating the database if it doesn't exist, obtaining an exclusive lock on the + file, reading the meta pages, & memory-mapping the file. + +- `DB.Begin()` - Starts a read-only or read-write transaction depending on the + value of the `writable` argument. This requires briefly obtaining the "meta" + lock to keep track of open transactions. Only one read-write transaction can + exist at a time so the "rwlock" is acquired during the life of a read-write + transaction. + +- `Bucket.Put()` - Writes a key/value pair into a bucket. After validating the + arguments, a cursor is used to traverse the B+tree to the page and position + where they key & value will be written. Once the position is found, the bucket + materializes the underlying page and the page's parent pages into memory as + "nodes". These nodes are where mutations occur during read-write transactions. + These changes get flushed to disk during commit. + +- `Bucket.Get()` - Retrieves a key/value pair from a bucket. This uses a cursor + to move to the page & position of a key/value pair. During a read-only + transaction, the key and value data is returned as a direct reference to the + underlying mmap file so there's no allocation overhead. For read-write + transactions, this data may reference the mmap file or one of the in-memory + node values. + +- `Cursor` - This object is simply for traversing the B+tree of on-disk pages + or in-memory nodes. It can seek to a specific key, move to the first or last + value, or it can move forward or backward. The cursor handles the movement up + and down the B+tree transparently to the end user. + +- `Tx.Commit()` - Converts the in-memory dirty nodes and the list of free pages + into pages to be written to disk. Writing to disk then occurs in two phases. + First, the dirty pages are written to disk and an `fsync()` occurs. Second, a + new meta page with an incremented transaction ID is written and another + `fsync()` occurs. This two phase write ensures that partially written data + pages are ignored in the event of a crash since the meta page pointing to them + is never written. Partially written meta pages are invalidated because they + are written with a checksum. + +If you have additional notes that could be helpful for others, please submit +them via pull request. + + +## Other Projects Using Bolt + +Below is a list of public, open source projects that use Bolt: + +* [Algernon](https://github.com/xyproto/algernon) - A HTTP/2 web server with built-in support for Lua.

A list of tests called guard. Each test in guard checks a single entry in the database. It may check +// for the absence or presence of a value, or compare with a given value. Two different tests in the guard +// may apply to the same or different entries in the database. All tests in the guard are applied and +// MultiOp returns the results. If all tests are true, MultiOp executes t op (see item 2 below), otherwise +// it executes f op (see item 3 below). +// 2. A list of database operations called t op. Each operation in the list is either an insert, delete, or +// lookup operation, and applies to a single database entry. Two different operations in the list may apply +// to the same or different entries in the database. These operations are executed +// if guard evaluates to +// true. +// 3.

As of 2016, it is **the most widely used** Raft library in production, serving tens of thousands clusters each day. It powers distributed systems such as etcd, Kubernetes, Docker Swarm, Cloud Foundry Diego, CockroachDB, TiDB, Project Calico, Flannel, Hyperledger and more. + +Most Raft implementations have a monolithic design, including storage handling, messaging serialization, and network transport. This library instead follows a minimalistic design philosophy by only implementing the core raft algorithm. This minimalism buys flexibility, determinism, and performance. + +To keep the codebase small as well as provide flexibility, the library only implements the Raft algorithm; both network and disk IO are left to the user. Library users must implement their own transportation layer for message passing between Raft peers over the wire. Similarly, users must implement their own storage layer to persist the Raft log and state. + +In order to easily test the Raft library, its behavior should be deterministic. To achieve this determinism, the library models Raft as a state machine. The state machine takes a `Message` as input. A message can either be a local timer update or a network message sent from a remote peer. The state machine's output is a 3-tuple `{[]Messages, []LogEntries, NextState}` consisting of an array of `Messages`, `log entries`, and `Raft state changes`. For state machines with the same state, the same state machine input should always generate the same state machine output. + +A simple example application, _raftexample_, is also available to help illustrate how to use this package in practice: https://github.com/etcd-io/etcd/tree/main/contrib/raftexample + +# Features + +This raft implementation is a full feature implementation of Raft protocol. Features includes: + +- Leader election +- Log replication +- Log compaction +- Membership changes +- Leadership transfer extension +- Efficient linearizable read-only queries served by both the leader and followers + - leader checks with quorum and bypasses Raft log before processing read-only queries + - followers asks leader to get a safe read index before processing read-only queries +- More efficient lease-based linearizable read-only queries served by both the leader and followers + - leader bypasses Raft log and processing read-only queries locally + - followers asks leader to get a safe read index before processing read-only queries + - this approach relies on the clock of the all the machines in raft group + +This raft implementation also includes a few optional enhancements: + +- Optimistic pipelining to reduce log replication latency +- Flow control for log replication +- Batching Raft messages to reduce synchronized network I/O calls +- Batching log entries to reduce disk synchronized I/O +- Writing to leader's disk in parallel +- Internal proposal redirection from followers to leader +- Automatic stepping down when the leader loses quorum +- Protection against unbounded log growth when quorum is lost + +## Notable Users + +- [cockroachdb](https://github.com/cockroachdb/cockroach) A Scalable, Survivable, Strongly-Consistent SQL Database +- [dgraph](https://github.com/dgraph-io/dgraph) A Scalable, Distributed, Low Latency, High Throughput Graph Database +- [etcd](https://github.com/etcd-io/etcd) A distributed reliable key-value store +- [tikv](https://github.com/pingcap/tikv) A Distributed transactional key value database powered by Rust and Raft +- [swarmkit](https://github.com/docker/swarmkit) A toolkit for orchestrating distributed systems at any scale. +- [chain core](https://github.com/chain/chain) Software for operating permissioned, multi-asset blockchain networks + +## Usage + +The primary object in raft is a Node. Either start a Node from scratch using raft.StartNode or start a Node from some initial state using raft.RestartNode. + +To start a three-node cluster +```go + storage := raft.NewMemoryStorage() + c := &raft.Config{ + ID: 0x01, + ElectionTick: 10, + HeartbeatTick: 1, + Storage: storage, + MaxSizePerMsg: 4096, + MaxInflightMsgs: 256, + } + // Set peer list to the other nodes in the cluster. + // Note that they need to be started separately as well. + n := raft.StartNode(c, []raft.Peer{{ID: 0x02}, {ID: 0x03}}) +``` + +Start a single node cluster, like so: +```go + // Create storage and config as shown above. + // Set peer list to itself, so this node can become the leader of this single-node cluster. + peers := []raft.Peer{{ID: 0x01}} + n := raft.StartNode(c, peers) +``` + +To allow a new node to join this cluster, do not pass in any peers. First, add the node to the existing cluster by calling `ProposeConfChange` on any existing node inside the cluster. Then, start the node with an empty peer list, like so: +```go + // Create storage and config as shown above. + n := raft.StartNode(c, nil) +``` + +To restart a node from previous state: +```go + storage := raft.NewMemoryStorage() + + // Recover the in-memory storage from persistent snapshot, state and entries. + storage.ApplySnapshot(snapshot) + storage.SetHardState(state) + storage.Append(entries) + + c := &raft.Config{ + ID: 0x01, + ElectionTick: 10, + HeartbeatTick: 1, + Storage: storage, + MaxSizePerMsg: 4096, + MaxInflightMsgs: 256, + } + + // Restart raft without peer information. + // Peer information is already included in the storage. + n := raft.RestartNode(c) +``` + +After creating a Node, the user has a few responsibilities: + +First, read from the Node.Ready() channel and process the updates it contains. These steps may be performed in parallel, except as noted in step 2. + +1. Write Entries, HardState and Snapshot to persistent storage in order, i.e. Entries first, then HardState and Snapshot if they are not empty. If persistent storage supports atomic writes then all of them can be written together. Note that when writing an Entry with Index i, any previously-persisted entries with Index >= i must be discarded. + +2. Send all Messages to the nodes named in the To field. It is important that no messages be sent until the latest HardState has been persisted to disk, and all Entries written by any previous Ready batch (Messages may be sent while entries from the same batch are being persisted). To reduce the I/O latency, an optimization can be applied to make leader write to disk in parallel with its followers (as explained at section 10.2.1 in Raft thesis). If any Message has type MsgSnap, call Node.ReportSnapshot() after it has been sent (these messages may be large). Note: Marshalling messages is not thread-safe; it is important to make sure that no new entries are persisted while marshalling. The easiest way to achieve this is to serialise the messages directly inside the main raft loop. + +3. Apply Snapshot (if any) and CommittedEntries to the state machine. If any committed Entry has Type EntryConfChange, call Node.ApplyConfChange() to apply it to the node. The configuration change may be cancelled at this point by setting the NodeID field to zero before calling ApplyConfChange (but ApplyConfChange must be called one way or the other, and the decision to cancel must be based solely on the state machine and not external information such as the observed health of the node). + +4. Call Node.Advance() to signal readiness for the next batch of updates. This may be done at any time after step 1, although all updates must be processed in the order they were returned by Ready. + +Second, all persisted log entries must be made available via an implementation of the Storage interface. The provided MemoryStorage type can be used for this (if repopulating its state upon a restart), or a custom disk-backed implementation can be supplied. + +Third, after receiving a message from another node, pass it to Node.Step: + +```go + func recvRaftRPC(ctx context.Context, m raftpb.Message) { + n.Step(ctx, m) + } +``` + +Finally, call `Node.Tick()` at regular intervals (probably via a `time.Ticker`). Raft has two important timeouts: heartbeat and the election timeout. However, internally to the raft package time is represented by an abstract "tick". + +The total state machine handling loop will look something like this: + +```go + for { + select { + case <-s.Ticker: + n.Tick() + case rd := <-s.Node.Ready(): + saveToStorage(rd.HardState, rd.Entries, rd.Snapshot) + send(rd.Messages) + if !raft.IsEmptySnap(rd.Snapshot) { + processSnapshot(rd.Snapshot) + } + for _, entry := range rd.CommittedEntries { + process(entry) + if entry.Type == raftpb.EntryConfChange { + var cc raftpb.ConfChange + cc.Unmarshal(entry.Data) + s.Node.ApplyConfChange(cc) + } + } + s.Node.Advance() + case <-s.done: + return + } + } +``` + +To propose changes to the state machine from the node to take application data, serialize it into a byte slice and call: + +```go + n.Propose(ctx, data) +``` + +If the proposal is committed, data will appear in committed entries with type raftpb.EntryNormal. There is no guarantee that a proposed command will be committed; the command may have to be reproposed after a timeout. + +To add or remove node in a cluster, build ConfChange struct 'cc' and call: + +```go + n.ProposeConfChange(ctx, cc) +``` + +After config change is committed, some committed entry with type raftpb.EntryConfChange will be returned. This must be applied to node through: + +```go + var cc raftpb.ConfChange + cc.Unmarshal(data) + n.ApplyConfChange(cc) +``` + +Note: An ID represents a unique node in a cluster for all time. A +given ID MUST be used only once even if the old node has been removed. +This means that for example IP addresses make poor node IDs since they +may be reused. Node IDs must be non-zero. + +## Implementation notes + +This implementation is up to date with the final Raft thesis (https://github.com/ongardie/dissertation/blob/master/stanford.pdf), although this implementation of the membership change protocol differs somewhat from that described in chapter 4. The key invariant that membership changes happen one node at a time is preserved, but in our implementation the membership change takes effect when its entry is applied, not when it is added to the log (so the entry is committed under the old membership instead of the new). This is equivalent in terms of safety, since the old and new configurations are guaranteed to overlap. + +To ensure there is no attempt to commit two membership changes at once by matching log positions (which would be unsafe since they should have different quorum requirements), any proposed membership change is simply disallowed while any uncommitted change appears in the leader's log. + +This approach introduces a problem when removing a member from a two-member cluster: If one of the members dies before the other one receives the commit of the confchange entry, then the member cannot be removed any more since the cluster cannot make progress. For this reason it is highly recommended to use three or more nodes in every cluster. + +## Go docs + +More detailed development documentation can be found in go docs: https://pkg.go.dev/go.etcd.io/etcd/raft/v3. \ No newline at end of file diff --git a/vendor/go.etcd.io/etcd/raft/v3/bootstrap.go b/vendor/go.etcd.io/etcd/raft/v3/bootstrap.go new file mode 100644 index 000000000..824bd5f51 --- /dev/null +++ b/vendor/go.etcd.io/etcd/raft/v3/bootstrap.go @@ -0,0 +1,80 @@ +// Copyright 2015 The etcd Authors +// +// Licensed under the Apache License, Version 2.0 (the "License"); +// you may not use this file except in compliance with the License. +// You may obtain a copy of the License at +// +// http://www.apache.org/licenses/LICENSE-2.0 +// +// Unless required by applicable law or agreed to in writing, software +// distributed under the License is distributed on an "AS IS" BASIS, +// WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. +// See the License for the specific language governing permissions and +// limitations under the License. + +package raft + +import ( + "errors" + + pb "go.etcd.io/etcd/raft/v3/raftpb" +) + +// Bootstrap initializes the RawNode for first use by appending configuration +// changes for the supplied peers.

You either start a Node from scratch +using raft.StartNode or start a Node from some initial state using raft.RestartNode. + +To start a node from scratch: + + storage := raft.NewMemoryStorage() + c := &Config{ + ID: 0x01, + ElectionTick: 10, + HeartbeatTick: 1, + Storage: storage, + MaxSizePerMsg: 4096, + MaxInflightMsgs: 256, + } + n := raft.StartNode(c, []raft.Peer{{ID: 0x02}, {ID: 0x03}}) + +To restart a node from previous state: + + storage := raft.NewMemoryStorage() + + // recover the in-memory storage from persistent + // snapshot, state and entries. + storage.ApplySnapshot(snapshot) + storage.SetHardState(state) + storage.Append(entries) + + c := &Config{ + ID: 0x01, + ElectionTick: 10, + HeartbeatTick: 1, + Storage: storage, + MaxSizePerMsg: 4096, + MaxInflightMsgs: 256, + } + + // restart raft without peer information. + // peer information is already included in the storage. + n := raft.RestartNode(c) + +Now that you are holding onto a Node you have a few responsibilities: + +First, you must read from the Node.Ready() channel and process the updates +it contains. These steps may be performed in parallel, except as noted in step +2. + +1. Write HardState, Entries, and Snapshot to persistent storage if they are +not empty. Note that when writing an Entry with Index i, any +previously-persisted entries with Index >= i must be discarded. + +2. Send all Messages to the nodes named in the To field. It is important that +no messages be sent until the latest HardState has been persisted to disk, +and all Entries written by any previous Ready batch (Messages may be sent while +entries from the same batch are being persisted). To reduce the I/O latency, an +optimization can be applied to make leader write to disk in parallel with its +followers (as explained at section 10.2.1 in Raft thesis). If any Message has type +MsgSnap, call Node.ReportSnapshot() after it has been sent (these messages may be +large). + +Note: Marshalling messages is not thread-safe; it is important that you +make sure that no new entries are persisted while marshalling. +The easiest way to achieve this is to serialize the messages directly inside +your main raft loop. + +3. Apply Snapshot (if any) and CommittedEntries to the state machine. +If any committed Entry has Type EntryConfChange, call Node.ApplyConfChange() +to apply it to the node. The configuration change may be cancelled at this point +by setting the NodeID field to zero before calling ApplyConfChange +(but ApplyConfChange must be called one way or the other, and the decision to cancel +must be based solely on the state machine and not external information such as +the observed health of the node). + +4. Call Node.Advance() to signal readiness for the next batch of updates. +This may be done at any time after step 1, although all updates must be processed +in the order they were returned by Ready. + +Second, all persisted log entries must be made available via an +implementation of the Storage interface. The provided MemoryStorage +type can be used for this (if you repopulate its state upon a +restart), or you can supply your own disk-backed implementation. + +Third, when you receive a message from another node, pass it to Node.Step: + + func recvRaftRPC(ctx context.Context, m raftpb.Message) { + n.Step(ctx, m) + } + +Finally, you need to call Node.Tick() at regular intervals (probably +via a time.Ticker). Raft has two important timeouts: heartbeat and the +election timeout. However, internally to the raft package time is +represented by an abstract "tick". + +The total state machine handling loop will look something like this: + + for { + select { + case <-s.Ticker: + n.Tick() + case rd := <-s.Node.Ready(): + saveToStorage(rd.State, rd.Entries, rd.Snapshot) + send(rd.Messages) + if !raft.IsEmptySnap(rd.Snapshot) { + processSnapshot(rd.Snapshot) + } + for _, entry := range rd.CommittedEntries { + process(entry) + if entry.Type == raftpb.EntryConfChange { + var cc raftpb.ConfChange + cc.Unmarshal(entry.Data) + s.Node.ApplyConfChange(cc) + } + } + s.Node.Advance() + case <-s.done: + return + } + } + +To propose changes to the state machine from your node take your application +data, serialize it into a byte slice and call: + + n.Propose(ctx, data) + +If the proposal is committed, data will appear in committed entries with type +raftpb.EntryNormal. There is no guarantee that a proposed command will be +committed; you may have to re-propose after a timeout. + +To add or remove a node in a cluster, build ConfChange struct 'cc' and call: + + n.ProposeConfChange(ctx, cc) + +After config change is committed, some committed entry with type +raftpb.EntryConfChange will be returned. You must apply it to node through: + + var cc raftpb.ConfChange + cc.Unmarshal(data) + n.ApplyConfChange(cc) + +Note: An ID represents a unique node in a cluster for all time. A +given ID MUST be used only once even if the old node has been removed. +This means that for example IP addresses make poor node IDs since they +may be reused. Node IDs must be non-zero. + +Implementation notes + +This implementation is up to date with the final Raft thesis +(https://github.com/ongardie/dissertation/blob/master/stanford.pdf), although our +implementation of the membership change protocol differs somewhat from +that described in chapter 4. The key invariant that membership changes +happen one node at a time is preserved, but in our implementation the +membership change takes effect when its entry is applied, not when it +is added to the log (so the entry is committed under the old +membership instead of the new). This is equivalent in terms of safety, +since the old and new configurations are guaranteed to overlap. + +To ensure that we do not attempt to commit two membership changes at +once by matching log positions (which would be unsafe since they +should have different quorum requirements), we simply disallow any +proposed membership change while any uncommitted change appears in +the leader's log. + +This approach introduces a problem when you try to remove a member +from a two-member cluster: If one of the members dies before the +other one receives the commit of the confchange entry, then the member +cannot be removed any more since the cluster cannot make progress. +For this reason it is highly recommended to use three or more nodes in +every cluster. + +MessageType + +Package raft sends and receives message in Protocol Buffer format (defined +in raftpb package). Each state (follower, candidate, leader) implements its +own 'step' method ('stepFollower', 'stepCandidate', 'stepLeader') when +advancing with the given raftpb.Message. Each step is determined by its +raftpb.MessageType. Note that every step is checked by one common method +'Step' that safety-checks the terms of node and incoming message to prevent +stale log entries: + + 'MsgHup' is used for election. If a node is a follower or candidate, the + 'tick' function in 'raft' struct is set as 'tickElection'. If a follower or + candidate has not received any heartbeat before the election timeout, it + passes 'MsgHup' to its Step method and becomes (or remains) a candidate to + start a new election. + + 'MsgBeat' is an internal type that signals the leader to send a heartbeat of + the 'MsgHeartbeat' type. If a node is a leader, the 'tick' function in + the 'raft' struct is set as 'tickHeartbeat', and triggers the leader to + send periodic 'MsgHeartbeat' messages to its followers. + + 'MsgProp' proposes to append data to its log entries. This is a special + type to redirect proposals to leader. Therefore, send method overwrites + raftpb.Message's term with its HardState's term to avoid attaching its + local term to 'MsgProp'. When 'MsgProp' is passed to the leader's 'Step' + method, the leader first calls the 'appendEntry' method to append entries + to its log, and then calls 'bcastAppend' method to send those entries to + its peers. When passed to candidate, 'MsgProp' is dropped. When passed to + follower, 'MsgProp' is stored in follower's mailbox(msgs) by the send + method. It is stored with sender's ID and later forwarded to leader by + rafthttp package. + + 'MsgApp' contains log entries to replicate. A leader calls bcastAppend, + which calls sendAppend, which sends soon-to-be-replicated logs in 'MsgApp' + type. When 'MsgApp' is passed to candidate's Step method, candidate reverts + back to follower, because it indicates that there is a valid leader sending + 'MsgApp' messages. Candidate and follower respond to this message in + 'MsgAppResp' type. + + 'MsgAppResp' is response to log replication request('MsgApp'). When + 'MsgApp' is passed to candidate or follower's Step method, it responds by + calling 'handleAppendEntries' method, which sends 'MsgAppResp' to raft + mailbox. + + 'MsgVote' requests votes for election. When a node is a follower or + candidate and 'MsgHup' is passed to its Step method, then the node calls + 'campaign' method to campaign itself to become a leader. Once 'campaign' + method is called, the node becomes candidate and sends 'MsgVote' to peers + in cluster to request votes. When passed to leader or candidate's Step + method and the message's Term is lower than leader's or candidate's, + 'MsgVote' will be rejected ('MsgVoteResp' is returned with Reject true). + If leader or candidate receives 'MsgVote' with higher term, it will revert + back to follower. When 'MsgVote' is passed to follower, it votes for the + sender only when sender's last term is greater than MsgVote's term or + sender's last term is equal to MsgVote's term but sender's last committed + index is greater than or equal to follower's. + + 'MsgVoteResp' contains responses from voting request. When 'MsgVoteResp' is + passed to candidate, the candidate calculates how many votes it has won. If + it's more than majority (quorum), it becomes leader and calls 'bcastAppend'. + If candidate receives majority of votes of denials, it reverts back to + follower. + + 'MsgPreVote' and 'MsgPreVoteResp' are used in an optional two-phase election + protocol. When Config.PreVote is true, a pre-election is carried out first + (using the same rules as a regular election), and no node increases its term + number unless the pre-election indicates that the campaigning node would win. + This minimizes disruption when a partitioned node rejoins the cluster. + + 'MsgSnap' requests to install a snapshot message. When a node has just + become a leader or the leader receives 'MsgProp' message, it calls + 'bcastAppend' method, which then calls 'sendAppend' method to each + follower. In 'sendAppend', if a leader fails to get term or entries, + the leader requests snapshot by sending 'MsgSnap' type message. + + 'MsgSnapStatus' tells the result of snapshot install message. When a + follower rejected 'MsgSnap', it indicates the snapshot request with + 'MsgSnap' had failed from network issues which causes the network layer + to fail to send out snapshots to its followers. Then leader considers + follower's progress as probe. When 'MsgSnap' were not rejected, it + indicates that the snapshot succeeded and the leader sets follower's + progress to probe and resumes its log replication. + + 'MsgHeartbeat' sends heartbeat from leader. When 'MsgHeartbeat' is passed + to candidate and message's term is higher than candidate's, the candidate + reverts back to follower and updates its committed index from the one in + this heartbeat. And it sends the message to its mailbox. When + 'MsgHeartbeat' is passed to follower's Step method and message's term is + higher than follower's, the follower updates its leaderID with the ID + from the message. + + 'MsgHeartbeatResp' is a response to 'MsgHeartbeat'.

Unless + the approver explicitly stated that their approval will persist across + changes it should be assumed that the PR needs their review again. Other + project members (e.g. approvers, maintainers) can help with this if there are + any questions or if you forget to clear reviews. +* It has been open for review for at least one working day. This gives + people reasonable time to review. +* Trivial change (typo, cosmetic, doc, etc.) doesn't have to wait for + one day. +* `CHANGELOG.md` has been updated to reflect what has been + added, changed, removed, or fixed. +* Urgent fix can take exception as long as it has been actively + communicated. + +Any Maintainer can merge the PR once it is **ready to merge**. + +## Style Guide + +* Make sure to run `make precommit` - this will find and fix the code + formatting. +* Check [opentelemetry-go Style Guide](https://github.com/open-telemetry/opentelemetry-go/blob/main/CONTRIBUTING.md#style-guide) + +## Adding a new Contrib package + +To add a new contrib package follow an existing one.

(#1373) +- Adds semantic conventions for exceptions. (#1492) +- Added Jaeger Environment variables: `OTEL_EXPORTER_JAEGER_AGENT_HOST`, `OTEL_EXPORTER_JAEGER_AGENT_PORT` + These environment variables can be used to override Jaeger agent hostname and port (#1752) +- Option `ExportTimeout` was added to batch span processor. (#1755) +- `trace.TraceFlags` is now a defined type over `byte` and `WithSampled(bool) TraceFlags` and `IsSampled() bool` methods have been added to it.

(#1771) +- The Jaeger exporter now reports dropped attributes for a Span event in the exported log. (#1771) +- Adds test to check BatchSpanProcessor ignores `OnEnd` and `ForceFlush` post `Shutdown`. (#1772) +- Extract resource attributes from the `OTEL_RESOURCE_ATTRIBUTES` environment variable and merge them with the `resource.Default` resource as well as resources provided to the `TracerProvider` and metric `Controller`. (#1785) +- Added `WithOSType` resource configuration option to set OS (Operating System) type resource attribute (`os.type`).

(#1821) + +### Fixed + +- The `Span.IsRecording` implementation from `go.opentelemetry.io/otel/sdk/trace` always returns false when not being sampled. (#1750) +- The Jaeger exporter now correctly sets tags for the Span status code and message. + This means it uses the correct tag keys (`"otel.status_code"`, `"otel.status_description"`) and does not set the status message as a tag unless it is set on the span. (#1761) +- The Jaeger exporter now correctly records Span event's names using the `"event"` key for a tag. + Additionally, this tag is overridden, as specified in the OTel specification, if the event contains an attribute with that key. (#1768) +- Zipkin Exporter: Ensure mapping between OTel and Zipkin span data complies with the specification. (#1688) +- Fixed typo for default service name in Jaeger Exporter. (#1797) +- Fix flaky OTLP for the reconnnection of the client connection. (#1527, #1814) + +### Changed + +- Span `RecordError` now records an `exception` event to comply with the semantic convention specification. (#1492) +- Jaeger exporter was updated to use thrift v0.14.1. (#1712) +- Migrate from using internally built and maintained version of the OTLP to the one hosted at `go.opentelemetry.io/proto/otlp`. (#1713) +- Migrate from using `github.com/gogo/protobuf` to `google.golang.org/protobuf` to match `go.opentelemetry.io/proto/otlp`. (#1713) +- The storage of a local or remote Span in a `context.Context` using its SpanContext is unified to store just the current Span. + The Span's SpanContext can now self-identify as being remote or not. + This means that `"go.opentelemetry.io/otel/trace".ContextWithRemoteSpanContext` will now overwrite any existing current Span, not just existing remote Spans, and make it the current Span in a `context.Context`. (#1731) +- Improve OTLP/gRPC exporter connection errors. (#1737) +- Information about a parent span context in a `"go.opentelemetry.io/otel/export/trace".SpanSnapshot` is unified in a new `Parent` field. + The existing `ParentSpanID` and `HasRemoteParent` fields are removed in favor of this. (#1748) +- The `ParentContext` field of the `"go.opentelemetry.io/otel/sdk/trace".SamplingParameters` is updated to hold a `context.Context` containing the parent span. + This changes it to make `SamplingParameters` conform with the OpenTelemetry specification. (#1749) +- Updated Jaeger Environment Variables: `JAEGER_ENDPOINT`, `JAEGER_USER`, `JAEGER_PASSWORD` + to `OTEL_EXPORTER_JAEGER_ENDPOINT`, `OTEL_EXPORTER_JAEGER_USER`, `OTEL_EXPORTER_JAEGER_PASSWORD` + in compliance with OTel spec (#1752) +- Modify `BatchSpanProcessor.ForceFlush` to abort after timeout/cancellation. (#1757) +- The `DroppedAttributeCount` field of the `Span` in the `go.opentelemetry.io/otel` package now only represents the number of attributes dropped for the span itself. + It no longer is a conglomerate of itself, events, and link attributes that have been dropped. (#1771) +- Make `ExportSpans` in Jaeger Exporter honor context deadline. (#1773) +- Modify Zipkin Exporter default service name, use default resouce's serviceName instead of empty. (#1777) +- The `go.opentelemetry.io/otel/sdk/export/trace` package is merged into the `go.opentelemetry.io/otel/sdk/trace` package. (#1778) +- The prometheus.InstallNewPipeline example is moved from comment to example test (#1796) +- The convenience functions for the stdout exporter have been updated to return the `TracerProvider` implementation and enable the shutdown of the exporter. (#1800) +- Replace the flush function returned from the Jaeger exporter's convenience creation functions (`InstallNewPipeline` and `NewExportPipeline`) with the `TracerProvider` implementation they create. + This enables the caller to shutdown and flush using the related `TracerProvider` methods. (#1822) +- Updated the Jaeger exporter to have a default enpoint, `http://localhost:14250`, for the collector. (#1824) +- Changed the function `WithCollectorEndpoint` in the Jaeger exporter to no longer accept an endpoint as an argument. + The endpoint can be passed with the `CollectorEndpointOption` using the `WithEndpoint` function or by setting the `OTEL_EXPORTER_JAEGER_ENDPOINT` environment variable value appropriately. (#1824) +- The Jaeger exporter no longer batches exported spans itself, instead it relies on the SDK's `BatchSpanProcessor` for this functionality. (#1830) +- The Jaeger exporter creation functions (`NewRawExporter`, `NewExportPipeline`, and `InstallNewPipeline`) no longer accept the removed `Option` type as a variadic argument. (#1830) + +### Removed + +- Removed Jaeger Environment variables: `JAEGER_SERVICE_NAME`, `JAEGER_DISABLED`, `JAEGER_TAGS` + These environment variables will no longer be used to override values of the Jaeger exporter (#1752) +- No longer set the links for a `Span` in `go.opentelemetry.io/otel/sdk/trace` that is configured to be a new root. + This is unspecified behavior that the OpenTelemetry community plans to standardize in the future. + To prevent backwards incompatible changes when it is specified, these links are removed. (#1726) +- Setting error status while recording error with Span from oteltest package. (#1729) +- The concept of a remote and local Span stored in a context is unified to just the current Span. + Because of this `"go.opentelemetry.io/otel/trace".RemoteSpanContextFromContext` is removed as it is no longer needed. + Instead, `"go.opentelemetry.io/otel/trace".SpanContextFromContex` can be used to return the current Span. + If needed, that Span's `SpanContext.IsRemote()` can then be used to determine if it is remote or not. (#1731) +- The `HasRemoteParent` field of the `"go.opentelemetry.io/otel/sdk/trace".SamplingParameters` is removed. + This field is redundant to the information returned from the `Remote` method of the `SpanContext` held in the `ParentContext` field. (#1749) +- The `trace.FlagsDebug` and `trace.FlagsDeferred` constants have been removed and will be localized to the B3 propagator. (#1770) +- Remove `Process` configuration, `WithProcessFromEnv` and `ProcessFromEnv`, and type from the Jaeger exporter package. + The information that could be configured in the `Process` struct should be configured in a `Resource` instead. (#1776, #1804) +- Remove the `WithDisabled` option from the Jaeger exporter. + To disable the exporter unregister it from the `TracerProvider` or use a no-operation `TracerProvider`. (#1806) +- Removed the functions `CollectorEndpointFromEnv` and `WithCollectorEndpointOptionFromEnv` from the Jaeger exporter. + These functions for retrieving specific environment variable values are redundant of other internal functions and + are not intended for end user use. (#1824) +- Removed the Jaeger exporter `WithSDKOptions` `Option`. + This option was used to set SDK options for the exporter creation convenience functions. + These functions are provided as a way to easily setup or install the exporter with what are deemed reasonable SDK settings for common use cases. + If the SDK needs to be configured differently, the `NewRawExporter` function and direct setup of the SDK with the desired settings should be used. (#1825) +- The `WithBufferMaxCount` and `WithBatchMaxCount` `Option`s from the Jaeger exporter are removed. + The exporter no longer batches exports, instead relying on the SDK's `BatchSpanProcessor` for this functionality. (#1830) +- The Jaeger exporter `Option` type is removed. + The type is no longer used by the exporter to configure anything. + All of the previous configuration these options provided were duplicates of SDK configuration. + They have all been removed in favor of using the SDK configuration and focuses the exporter configuration to be only about the endpoints it will send telemetry to. (#1830) + +## [0.19.0] - 2021-03-18 + +### Added + +- Added `Marshaler` config option to `otlphttp` to enable otlp over json or protobufs. (#1586) +- A `ForceFlush` method to the `"go.opentelemetry.io/otel/sdk/trace".TracerProvider` to flush all registered `SpanProcessor`s. (#1608) +- Added `WithSampler` and `WithSpanLimits` to tracer provider. (#1633, #1702) +- `"go.opentelemetry.io/otel/trace".SpanContext` now has a `remote` property, and `IsRemote()` predicate, that is true when the `SpanContext` has been extracted from remote context data. (#1701) +- A `Valid` method to the `"go.opentelemetry.io/otel/attribute".KeyValue` type. (#1703) + +### Changed + +- `trace.SpanContext` is now immutable and has no exported fields. (#1573) + - `trace.NewSpanContext()` can be used in conjunction with the `trace.SpanContextConfig` struct to initialize a new `SpanContext` where all values are known. +- Update the `ForceFlush` method signature to the `"go.opentelemetry.io/otel/sdk/trace".SpanProcessor` to accept a `context.Context` and return an error. (#1608) +- Update the `Shutdown` method to the `"go.opentelemetry.io/otel/sdk/trace".TracerProvider` return an error on shutdown failure. (#1608) +- The SimpleSpanProcessor will now shut down the enclosed `SpanExporter` and gracefully ignore subsequent calls to `OnEnd` after `Shutdown` is called. (#1612) +- `"go.opentelemetry.io/sdk/metric/controller.basic".WithPusher` is replaced with `WithExporter` to provide consistent naming across project. (#1656) +- Added non-empty string check for trace `Attribute` keys. (#1659) +- Add `description` to SpanStatus only when `StatusCode` is set to error. (#1662) +- Jaeger exporter falls back to `resource.Default`'s `service.name` if the exported Span does not have one. (#1673) +- Jaeger exporter populates Jaeger's Span Process from Resource. (#1673) +- Renamed the `LabelSet` method of `"go.opentelemetry.io/otel/sdk/resource".Resource` to `Set`. (#1692) +- Changed `WithSDK` to `WithSDKOptions` to accept variadic arguments of `TracerProviderOption` type in `go.opentelemetry.io/otel/exporters/trace/jaeger` package. (#1693) +- Changed `WithSDK` to `WithSDKOptions` to accept variadic arguments of `TracerProviderOption` type in `go.opentelemetry.io/otel/exporters/trace/zipkin` package. (#1693) + +### Removed + +- Removed `serviceName` parameter from Zipkin exporter and uses resource instead. (#1549) +- Removed `WithConfig` from tracer provider to avoid overriding configuration. (#1633) +- Removed the exported `SimpleSpanProcessor` and `BatchSpanProcessor` structs. + These are now returned as a SpanProcessor interface from their respective constructors. (#1638) +- Removed `WithRecord()` from `trace.SpanOption` when creating a span. (#1660) +- Removed setting status to `Error` while recording an error as a span event in `RecordError`. (#1663) +- Removed `jaeger.WithProcess` configuration option. (#1673) +- Removed `ApplyConfig` method from `"go.opentelemetry.io/otel/sdk/trace".TracerProvider` and the now unneeded `Config` struct. (#1693) + +### Fixed + +- Jaeger Exporter: Ensure mapping between OTEL and Jaeger span data complies with the specification. (#1626) +- `SamplingResult.TraceState` is correctly propagated to a newly created span's `SpanContext`. (#1655) +- The `otel-collector` example now correctly flushes metric events prior to shutting down the exporter. (#1678) +- Do not set span status message in `SpanStatusFromHTTPStatusCode` if it can be inferred from `http.status_code`. (#1681) +- Synchronization issues in global trace delegate implementation. (#1686) +- Reduced excess memory usage by global `TracerProvider`. (#1687) + +## [0.18.0] - 2021-03-03 + +### Added + +- Added `resource.Default()` for use with meter and tracer providers. (#1507) +- `AttributePerEventCountLimit` and `AttributePerLinkCountLimit` for `SpanLimits`. (#1535) +- Added `Keys()` method to `propagation.TextMapCarrier` and `propagation.HeaderCarrier` to adapt `http.Header` to this interface. (#1544) +- Added `code` attributes to `go.opentelemetry.io/otel/semconv` package. (#1558) +- Compatibility testing suite in the CI system for the following systems. (#1567) + | OS | Go Version | Architecture | + | ------- | ---------- | ------------ | + | Ubuntu | 1.15 | amd64 | + | Ubuntu | 1.14 | amd64 | + | Ubuntu | 1.15 | 386 | + | Ubuntu | 1.14 | 386 | + | MacOS | 1.15 | amd64 | + | MacOS | 1.14 | amd64 | + | Windows | 1.15 | amd64 | + | Windows | 1.14 | amd64 | + | Windows | 1.15 | 386 | + | Windows | 1.14 | 386 | + +### Changed + +- Replaced interface `oteltest.SpanRecorder` with its existing implementation + `StandardSpanRecorder`. (#1542) +- Default span limit values to 128. (#1535) +- Rename `MaxEventsPerSpan`, `MaxAttributesPerSpan` and `MaxLinksPerSpan` to `EventCountLimit`, `AttributeCountLimit` and `LinkCountLimit`, and move these fields into `SpanLimits`.

(#881) +- The B3 propagator `SingleHeader` field has been replaced with `InjectEncoding`. + This new field can be set to combinations of the `B3Encoding` bitmasks and will inject trace information in these encodings. + If no encoding is set, the propagator will default to `MultipleHeader` encoding. (#882) +- The B3 propagator now extracts from either HTTP encoding of B3 (Single Header or Multiple Header) based on what is contained in the header. + Preference is given to Single Header encoding with Multiple Header being the fallback if Single Header is not found or is invalid. + This behavior change is made to dynamically support all correctly encoded traces received instead of having to guess the expected encoding prior to receiving.

(#881) +- The B3 propagator now correctly supports sampling only values (`b3: 0`, `b3: 1`, or `b3: d`) for a Single B3 Header. (#882) +- The B3 propagator now propagates the debug flag. + This removes the behavior of changing the debug flag into a set sampling bit. + Instead, this now follow the B3 specification and omits the `X-B3-Sampling` header.

(#915) +- The `grpctrace` instrumentation uses a span name conforming to the OpenTelemetry semantic conventions (does not contain a leading slash (`/`)). (#922) +- The `grpctrace` instrumentation includes an `rpc.method` attribute now set to the gRPC method name. (#900, #922) +- The `grpctrace` instrumentation `rpc.service` attribute now contains the package name if one exists. + This is in accordance with OpenTelemetry semantic conventions. (#922) +- Correlation Context extractor will no longer insert an empty map into the returned context when no valid values are extracted.

(#840) +- The `Aggregator.Checkpoint` API is renamed to `SynchronizedCopy` and adds an argument, a different `Aggregator` into which the copy is stored. (#812) +- The `export.Aggregator` contract is that `Update()` and `SynchronizedCopy()` are synchronized with each other. + All the aggregation interfaces (`Sum`, `LastValue`, ...) are not meant to be synchronized, as the caller is expected to synchronize aggregators at a higher level after the `Accumulator`. + Some of the `Aggregators` used unnecessary locking and that has been cleaned up. (#812) +- Use of `metric.Number` was replaced by `int64` now that we use `sync.Mutex` in the `MinMaxSumCount` and `Histogram` `Aggregators`.

(#567) + +### Removed + +- The vendor specific Stackdriver. It is now hosted on 3rd party vendor infrastructure. (#452) +- The `Unregister` method for metric observers as it is not in the OpenTelemetry specification. (#560) +- `GetDescriptor` from the metric SDK. (#575) +- The `Gauge` instrument from the metric API. (#537) + +### Fixed + +- Make histogram aggregator checkpoint consistent. (#438) +- Update README with import instructions and how to build and test. (#505) +- The default label encoding was updated to be unique. (#508) +- Use `NewRoot` in the othttp plugin for public endpoints. (#513) +- Fix data race in `BatchedSpanProcessor`. (#518) +- Skip test-386 for Mac OS 10.15.x (Catalina and upwards). #521 +- Use a variable-size array to represent ordered labels in maps. (#523) +- Update the OTLP protobuf and update changed import path. (#532) +- Use `StateLocker` implementation in `MinMaxSumCount`. (#546) +- Eliminate goroutine leak in histogram stress test. (#547) +- Update OTLP exporter with latest protobuf. (#550) +- Add filters to the othttp plugin. (#556) +- Provide an implementation of the `Header*` filters that do not depend on Go 1.14. (#565) +- Encode labels once during checkpoint. + The checkpoint function is executed in a single thread so we can do the encoding lazily before passing the encoded version of labels to the exporter. + This is a cheap and quick way to avoid encoding the labels on every collection interval. (#572) +- Run coverage over all packages in `COVERAGE_MOD_DIR`. (#573) + +## [0.2.3] - 2020-03-04 + +### Added + +- `RecordError` method on `Span`s in the trace API to Simplify adding error events to spans. (#473) +- Configurable push frequency for exporters setup pipeline. (#504) + +### Changed + +- Rename the `exporter` directory to `exporters`. + The `go.opentelemetry.io/otel/exporter/trace/jaeger` package was mistakenly released with a `v1.0.0` tag instead of `v0.1.0`. + This resulted in all subsequent releases not becoming the default latest. + A consequence of this was that all `go get`s pulled in the incompatible `v0.1.0` release of that package when pulling in more recent packages from other otel packages. + Renaming the `exporter` directory to `exporters` fixes this issue by renaming the package and therefore clearing any existing dependency tags. + Consequentially, this action also renames *all* exporter packages. (#502) + +### Removed + +- The `CorrelationContextHeader` constant in the `correlation` package is no longer exported. (#503) + +## [0.2.2] - 2020-02-27 + +### Added + +- `HTTPSupplier` interface in the propagation API to specify methods to retrieve and store a single value for a key to be associated with a carrier. (#467) +- `HTTPExtractor` interface in the propagation API to extract information from an `HTTPSupplier` into a context. (#467) +- `HTTPInjector` interface in the propagation API to inject information into an `HTTPSupplier.` (#467) +- `Config` and configuring `Option` to the propagator API. (#467) +- `Propagators` interface in the propagation API to contain the set of injectors and extractors for all supported carrier formats. (#467) +- `HTTPPropagator` interface in the propagation API to inject and extract from an `HTTPSupplier.` (#467) +- `WithInjectors` and `WithExtractors` functions to the propagator API to configure injectors and extractors to use. (#467) +- `ExtractHTTP` and `InjectHTTP` functions to apply configured HTTP extractors and injectors to a passed context. (#467) +- Histogram aggregator. (#433) +- `DefaultPropagator` function and have it return `trace.TraceContext` as the default context propagator. (#456) +- `AlwaysParentSample` sampler to the trace API. (#455) +- `WithNewRoot` option function to the trace API to specify the created span should be considered a root span. (#451) + + +### Changed + +- Renamed `WithMap` to `ContextWithMap` in the correlation package. (#481) +- Renamed `FromContext` to `MapFromContext` in the correlation package. (#481) +- Move correlation context propagation to correlation package. (#479) +- Do not default to putting remote span context into links. (#480) +- Propagators extrac +- `Tracer.WithSpan` updated to accept `StartOptions`. (#472) +- Renamed `MetricKind` to `Kind` to not stutter in the type usage. (#432) +- Renamed the `export` package to `metric` to match directory structure. (#432) +- Rename the `api/distributedcontext` package to `api/correlation`. (#444) +- Rename the `api/propagators` package to `api/propagation`. (#444) +- Move the propagators from the `propagators` package into the `trace` API package. (#444) +- Update `Float64Gauge`, `Int64Gauge`, `Float64Counter`, `Int64Counter`, `Float64Measure`, and `Int64Measure` metric methods to use value receivers instead of pointers. (#462) +- Moved all dependencies of tools package to a tools directory. (#466) + +### Removed + +- Binary propagators. (#467) +- NOOP propagator. (#467) + +### Fixed + +- Upgraded `github.com/golangci/golangci-lint` from `v1.21.0` to `v1.23.6` in `tools/`. (#492) +- Fix a possible nil-dereference crash (#478) +- Correct comments for `InstallNewPipeline` in the stdout exporter. (#483) +- Correct comments for `InstallNewPipeline` in the dogstatsd exporter. (#484) +- Correct comments for `InstallNewPipeline` in the prometheus exporter. (#482) +- Initialize `onError` based on `Config` in prometheus exporter. (#486) +- Correct module name in prometheus exporter README. (#475) +- Removed tracer name prefix from span names. (#430) +- Fix `aggregator_test.go` import package comment. (#431) +- Improved detail in stdout exporter. (#436) +- Fix a dependency issue (generate target should depend on stringer, not lint target) in Makefile. (#442) +- Reorders the Makefile targets within `precommit` target so we generate files and build the code before doing linting, so we can get much nicer errors about syntax errors from the compiler. (#442) +- Reword function documentation in gRPC plugin. (#446) +- Send the `span.kind` tag to Jaeger from the jaeger exporter. (#441) +- Fix `metadataSupplier` in the jaeger exporter to overwrite the header if existing instead of appending to it. (#441) +- Upgraded to Go 1.13 in CI. (#465) +- Correct opentelemetry.io URL in trace SDK documentation. (#464) +- Refactored reference counting logic in SDK determination of stale records. (#468) +- Add call to `runtime.Gosched` in instrument `acquireHandle` logic to not block the collector. (#469) + +## [0.2.1.1] - 2020-01-13 + +### Fixed + +- Use stateful batcher on Prometheus exporter fixing regresion introduced in #395. (#428) + +## [0.2.1] - 2020-01-08 + +### Added + +- Global meter forwarding implementation. + This enables deferred initialization for metric instruments registered before the first Meter SDK is installed. (#392) +- Global trace forwarding implementation. + This enables deferred initialization for tracers registered before the first Trace SDK is installed. (#406) +- Standardize export pipeline creation in all exporters. (#395) +- A testing, organization, and comments for 64-bit field alignment. (#418) +- Script to tag all modules in the project. (#414) + +### Changed + +- Renamed `propagation` package to `propagators`. (#362) +- Renamed `B3Propagator` propagator to `B3`. (#362) +- Renamed `TextFormatPropagator` propagator to `TextFormat`.

(#400) +- Renamed the `File` option in the stdout exporter to `Writer`. (#404) +- Renamed all `Options` to `Config` for all metric exports where this wasn't already the case. + +### Fixed + +- Aggregator import path corrected. (#421) +- Correct links in README.

(#365) +- Lint make target now implements automatic fixes with `golangci-lint` before a second run to report the remaining issues. (#360) +- Drop `GO111MODULE` environment variable in Makefile as Go 1.13 is the project specified minimum version and this is environment variable is not needed for that version of Go. (#359) +- Run the race checker for all test. (#354) +- Redundant commands in the Makefile are removed. (#354) +- Split the `generate` and `lint` targets of the Makefile. (#354) +- Renames `circle-ci` target to more generic `ci` in Makefile. (#354) +- Add example Prometheus binary to gitignore. (#358) +- Support negative numbers with the `MaxSumCount`. (#335) +- Resolve race conditions in `push_test.go` identified in #339. (#340) +- Use `/usr/bin/env bash` as a shebang in scripts rather than `/bin/bash`. (#336) +- Trace benchmark now tests both `AlwaysSample` and `NeverSample`. + Previously it was testing `AlwaysSample` twice. (#325) +- Trace benchmark now uses a `[]byte` for `TraceID` to fix failing test. (#325) +- Added a trace benchmark to test variadic functions in `setAttribute` vs `setAttributes` (#325) +- The `defaultkeys` batcher was only using the encoded label set as its map key while building a checkpoint. + This allowed distinct label sets through, but any metrics sharing a label set could be overwritten or merged incorrectly. + This was corrected. (#333) + + +## [0.1.2] - 2019-11-18 + +### Fixed + +- Optimized the `simplelru` map for attributes to reduce the number of allocations. (#328) +- Removed unnecessary unslicing of parameters that are already a slice.

You +can alternatively use `git` directly with: + +```sh +$ git clone https://github.com/open-telemetry/opentelemetry-go +``` + +(Note that `git clone` is *not* using the `go.opentelemetry.io/otel` name - +that name is a kind of a redirector to GitHub that `go get` can +understand, but `git` does not.) + +This would put the project in the `opentelemetry-go` directory in +current working directory. + +Enter the newly created directory and add your fork as a new remote: + +```sh +$ git remote add git@github.com:/opentelemetry-go +``` + +Check out a new branch, make modifications, run linters and tests, update +`CHANGELOG.md`, and push the branch to your fork: + +```sh +$ git checkout -b +# edit files +# update changelog +$ make precommit +$ git add -p +$ git commit +$ git push +``` + +Open a pull request against the main `opentelemetry-go` repo. Be sure to add the pull +request ID to the entry you added to `CHANGELOG.md`. + +### How to Receive Comments + +* If the PR is not ready for review, please put `[WIP]` in the title, + tag it as `work-in-progress`, or mark it as + [`draft`](https://github.blog/2019-02-14-introducing-draft-pull-requests/). +* Make sure CLA is signed and CI is clear. + +### How to Get PRs Merged + +A PR is considered to be **ready to merge** when: + +* It has received two approvals from Collaborators/Maintainers (at + different companies). This is not enforced through technical means + and a PR may be **ready to merge** with a single approval if the change + and its approach have been discussed and consensus reached. +* Feedback has been addressed. +* Any substantive changes to your PR will require that you clear any prior + Approval reviews, this includes changes resulting from other feedback. Unless + the approver explicitly stated that their approval will persist across + changes it should be assumed that the PR needs their review again. Other + project members (e.g. approvers, maintainers) can help with this if there are + any questions or if you forget to clear reviews. +* It has been open for review for at least one working day. This gives + people reasonable time to review. +* Trivial changes (typo, cosmetic, doc, etc.) do not have to wait for + one day and may be merged with a single Maintainer's approval. +* `CHANGELOG.md` has been updated to reflect what has been + added, changed, removed, or fixed. +* Urgent fix can take exception as long as it has been actively + communicated. + +Any Maintainer can merge the PR once it is **ready to merge**. + +## Design Choices + +As with other OpenTelemetry clients, opentelemetry-go follows the +[opentelemetry-specification](https://github.com/open-telemetry/opentelemetry-specification). + +It's especially valuable to read through the [library +guidelines](https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/library-guidelines.md). + +### Focus on Capabilities, Not Structure Compliance + +OpenTelemetry is an evolving specification, one where the desires and +use cases are clear, but the method to satisfy those uses cases are +not. + +As such, Contributions should provide functionality and behavior that +conforms to the specification, but the interface and structure is +flexible. + +It is preferable to have contributions follow the idioms of the +language rather than conform to specific API names or argument +patterns in the spec. + +For a deeper discussion, see: +https://github.com/open-telemetry/opentelemetry-specification/issues/165 + +## Style Guide + +One of the primary goals of this project is that it is actually used by +developers. With this goal in mind the project strives to build +user-friendly and idiomatic Go code adhering to the Go community's best +practices. + +For a non-comprehensive but foundational overview of these best practices +the [Effective Go](https://golang.org/doc/effective_go.html) documentation +is an excellent starting place. + +As a convenience for developers building this project the `make precommit` +will format, lint, validate, and in some cases fix the changes you plan to +submit. This check will need to pass for your changes to be able to be +merged. + +In addition to idiomatic Go, the project has adopted certain standards for +implementations of common patterns. These standards should be followed as a +default, and if they are not followed documentation needs to be included as +to the reasons why. + +### Configuration + +When creating an instantiation function for a complex `struct` it is useful +to allow variable number of options to be applied. However, the strong type +system of Go restricts the function design options. There are a few ways to +solve this problem, but we have landed on the following design. + +#### `config` + +Configuration should be held in a `struct` named `config`, or prefixed with +specific type name this Configuration applies to if there are multiple +`config` in the package. This `struct` must contain configuration options. + +```go +// config contains configuration options for a thing. +type config struct { + // options ... +} +``` + +In general the `config` `struct` will not need to be used externally to the +package and should be unexported. If, however, it is expected that the user +will likely want to build custom options for the configuration, the `config` +should be exported. Please, include in the documentation for the `config` +how the user can extend the configuration. + +It is important that `config` are not shared across package boundaries. +Meaning a `config` from one package should not be directly used by another. + +Optionally, it is common to include a `newConfig` function (with the same +naming scheme). This function wraps any defaults setting and looping over +all options to create a configured `config`. + +```go +// newConfig returns an appropriately configured config. +func newConfig([]Option) config { + // Set default values for config. + config := config{/* […] */} + for _, option := range options { + option.Apply(&config) + } + // Preform any validation here. + return config +} +``` + +If validation of the `config` options is also preformed this can return an +error as well that is expected to be handled by the instantiation function +or propagated to the user. + +Given the design goal of not having the user need to work with the `config`, +the `newConfig` function should also be unexported. + +#### `Option` + +To set the value of the options a `config` contains, a corresponding +`Option` interface type should be used. + +```go +type Option interface { + Apply(*config) +} +``` + +The name of the interface should be prefixed in the same way the +corresponding `config` is (if at all). + +#### Options + +All user configurable options for a `config` must have a related unexported +implementation of the `Option` interface and an exported configuration +function that wraps this implementation. + +The wrapping function name should be prefixed with `With*` (or in the +special case of a boolean options `Without*`) and should have the following +function signature. + +```go +func With*(…) Option { … } +``` + +##### `bool` Options + +```go +type defaultFalseOption bool + +func (o defaultFalseOption) Apply(c *config) { + c.Bool = bool(o) +} + +// WithOption sets a T* to have an option included. +func WithOption() Option { + return defaultFalseOption(true) +} +``` + +```go +type defaultTrueOption bool + +func (o defaultTrueOption) Apply(c *config) { + c.Bool = bool(o) +} + +// WithoutOption sets a T* to have Bool option excluded. +func WithoutOption() Option { + return defaultTrueOption(false) +} +```` + +##### Declared Type Options + +```go +type myTypeOption struct { + MyType MyType +} + +func (o myTypeOption) Apply(c *config) { + c.MyType = o.MyType +} + +// WithMyType sets T* to have include MyType. +func WithMyType(t MyType) Option { + return myTypeOption{t} +} +``` + +#### Instantiation + +Using this configuration pattern to configure instantiation with a `New*` +function. + +```go +func NewT*(options ...Option) T* {…} +``` + +Any required parameters can be declared before the variadic `options`. + +#### Dealing with Overlap + +Sometimes there are multiple complex `struct` that share common +configuration and also have distinct configuration. To avoid repeated +portions of `config`s, a common `config` can be used with the union of +options being handled with the `Option` interface. + +For example. + +```go +// config holds options for all animals. +type config struct { + Weight float64 + Color string + MaxAltitude float64 +} + +// DogOption apply Dog specific options. +type DogOption interface { + ApplyDog(*config) +} + +// BirdOption apply Bird specific options. +type BirdOption interface { + ApplyBird(*config) +} + +// Option apply options for all animals. +type Option interface { + BirdOption + DogOption +} + +type weightOption float64 +func (o weightOption) ApplyDog(c *config) { c.Weight = float64(o) } +func (o weightOption) ApplyBird(c *config) { c.Weight = float64(o) } +func WithWeight(w float64) Option { return weightOption(w) } + +type furColorOption string +func (o furColorOption) ApplyDog(c *config) { c.Color = string(o) } +func WithFurColor(c string) DogOption { return furColorOption(c) } + +type maxAltitudeOption float64 +func (o maxAltitudeOption) ApplyBird(c *config) { c.MaxAltitude = float64(o) } +func WithMaxAltitude(a float64) BirdOption { return maxAltitudeOption(a) } + +func NewDog(name string, o ...DogOption) Dog {…} +func NewBird(name string, o ...BirdOption) Bird {…} +``` + +### Interface Type + +To allow other developers to better comprehend the code, it is important +to ensure it is sufficiently documented. One simple measure that contributes +to this aim is self-documenting by naming method parameters. Therefore, +where appropriate, methods of every exported interface type should have +their parameters appropriately named. + +## Approvers and Maintainers + +Approvers: + +- [Evan Torrie](https://github.com/evantorrie), Verizon Media +- [Josh MacDonald](https://github.com/jmacd), LightStep +- [Sam Xie](https://github.com/XSAM) +- [David Ashpole](https://github.com/dashpole), Google +- [Gustavo Silva Paiva](https://github.com/paivagustavo), LightStep + +Maintainers: + +- [Anthony Mirabella](https://github.com/Aneurysm9), AWS +- [Tyler Yahn](https://github.com/MrAlias), Splunk + +### Become an Approver or a Maintainer + +See the [community membership document in OpenTelemetry community +repo](https://github.com/open-telemetry/community/blob/main/community-membership.md). diff --git a/vendor/go.opentelemetry.io/otel/LICENSE b/vendor/go.opentelemetry.io/otel/LICENSE new file mode 100644 index 000000000..261eeb9e9 --- /dev/null +++ b/vendor/go.opentelemetry.io/otel/LICENSE @@ -0,0 +1,201 @@ + Apache License + Version 2.0, January 2004 + http://www.apache.org/licenses/ + + TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION + + 1.

This project allows you to do just that for applications written in +Go. There are two steps to this process: instrument your application, and +configure an exporter. + +### Instrumentation + +To start capturing distributed traces and metric events from your application +it first needs to be instrumented. The easiest way to do this is by using an +instrumentation library for your code. Be sure to check out [the officially +supported instrumentation +libraries](https://github.com/open-telemetry/opentelemetry-go-contrib/tree/main/instrumentation). + +If you need to extend the telemetry an instrumentation library provides or want +to build your own instrumentation for your application directly you will need +to use the +[go.opentelemetry.io/otel/api](https://pkg.go.dev/go.opentelemetry.io/otel/api) +package. The included [examples](./example/) are a good way to see some +practical uses of this process. + +### Export + +Now that your application is instrumented to collect telemetry, it needs an +export pipeline to send that telemetry to an observability platform. + +You can find officially supported exporters [here](./exporters/) and in the +companion [contrib +repository](https://github.com/open-telemetry/opentelemetry-go-contrib/tree/main/exporters/metric). +Additionally, there are many vendor specific or 3rd party exporters for +OpenTelemetry. These exporters are broken down by +[trace](https://pkg.go.dev/go.opentelemetry.io/otel/sdk/export/trace?tab=importedby) +and +[metric](https://pkg.go.dev/go.opentelemetry.io/otel/sdk/export/metric?tab=importedby) +support. + +## Contributing + +See the [contributing documentation](CONTRIBUTING.md). diff --git a/vendor/go.opentelemetry.io/otel/RELEASING.md b/vendor/go.opentelemetry.io/otel/RELEASING.md new file mode 100644 index 000000000..71d23b47a --- /dev/null +++ b/vendor/go.opentelemetry.io/otel/RELEASING.md @@ -0,0 +1,81 @@ +# Release Process + +## Pre-Release + +Update go.mod for submodules to depend on the new release which will happen in the next step. + +1.

Instead + the only change that will have been included is to have updated that + modules dependency on this project's stable APIs. + * When an experimental module in contrib becomes stable a new stable + module version will be released and will include this now stable + module. The new stable module version will be an increment of the minor + version number and will be applied to all existing stable contrib + modules, this project's modules, and the newly stable module being + released. + * Contrib modules will be kept up to date with this project's releases. + * Due to the dependency contrib modules will implicitly have on this + project's modules the release of stable contrib modules to match the + released version number will be staggered after this project's release. + There is no explicit time guarantee for how long after this projects + release the contrib release will be. Effort should be made to keep them + as close in time as possible. + * No additional stable release in this project can be made until the + contrib repository has a matching stable release. + * No release can be made in the contrib repository after this project's + stable release except for a stable release of the contrib repository. +* GitHub releases will be made for all releases. +* Go modules will be made available at Go package mirrors. + +## Example Versioning Lifecycle + +To better understand the implementation of the above policy the following +example is provided. This project is simplified to include only the following +modules and their versions: + +* `otel`: `v0.14.0` +* `otel/trace`: `v0.14.0` +* `otel/metric`: `v0.14.0` +* `otel/baggage`: `v0.14.0` +* `otel/sdk/trace`: `v0.14.0` +* `otel/sdk/metric`: `v0.14.0` + +These modules have been developed to a point where the `otel/trace`, +`otel/baggage`, and `otel/sdk/trace` modules have reached a point that they +should be considered for a stable release. The `otel/metric` and +`otel/sdk/metric` are still under active development and the `otel` module +depends on both `otel/trace` and `otel/metric`. + +The `otel` package is refactored to remove its dependencies on `otel/metric` so +it can be released as stable as well. With that done the following release +candidates are made: + +* `otel`: `v1.0.0-rc.1` +* `otel/trace`: `v1.0.0-rc.1` +* `otel/baggage`: `v1.0.0-rc.1` +* `otel/sdk/trace`: `v1.0.0-rc.1` + +The `otel/metric` and `otel/sdk/metric` modules remain at `v0.14.0`. + +A few minor issues are discovered in the `otel/trace` package. These issues are +resolved with some minor, but backwards incompatible, changes and are released +as a second release candidate: + +* `otel`: `v1.0.0-rc.2` +* `otel/trace`: `v1.0.0-rc.2` +* `otel/baggage`: `v1.0.0-rc.2` +* `otel/sdk/trace`: `v1.0.0-rc.2` + +Notice that all module version numbers are incremented to adhere to our +versioning policy. + +After these release candidates have been evaluated to satisfaction, they are +released as version `v1.0.0`. + +* `otel`: `v1.0.0` +* `otel/trace`: `v1.0.0` +* `otel/baggage`: `v1.0.0` +* `otel/sdk/trace`: `v1.0.0` + +Since both the `go` utility and the Go module system support [the semantic +versioning definition of +precedence](https://semver.org/spec/v2.0.0.html#spec-item-11), this release +will correctly be interpreted as the successor to the previous release +candidates. + +Active development of this project continues. The `otel/metric` module now has +backwards incompatible changes to its API that need to be released and the +`otel/baggage` module has a minor bug fix that needs to be released. The +following release is made: + +* `otel`: `v1.0.1` +* `otel/trace`: `v1.0.1` +* `otel/metric`: `v0.15.0` +* `otel/baggage`: `v1.0.1` +* `otel/sdk/trace`: `v1.0.1` +* `otel/sdk/metric`: `v0.15.0` + +Notice that, again, all stable module versions are incremented in unison and +the `otel/sdk/metric` package, which depends on the `otel/metric` package, also +bumped its version. This bump of the `otel/sdk/metric` package makes sense +given their coupling, though it is not explicitly required by our versioning +policy. + +As we progress, the `otel/metric` and `otel/sdk/metric` packages have reached a +point where they should be evaluated for stability. The `otel` module is +reintegrated with the `otel/metric` package and the following release is made: + +* `otel`: `v1.1.0-rc.1` +* `otel/trace`: `v1.1.0-rc.1` +* `otel/metric`: `v1.1.0-rc.1` +* `otel/baggage`: `v1.1.0-rc.1` +* `otel/sdk/trace`: `v1.1.0-rc.1` +* `otel/sdk/metric`: `v1.1.0-rc.1` + +All the modules are evaluated and determined to a viable stable release. They +are then released as version `v1.1.0` (the minor version is incremented to +indicate the addition of new signal). + +* `otel`: `v1.1.0` +* `otel/trace`: `v1.1.0` +* `otel/metric`: `v1.1.0` +* `otel/baggage`: `v1.1.0` +* `otel/sdk/trace`: `v1.1.0` +* `otel/sdk/metric`: `v1.1.0` diff --git a/vendor/go.opentelemetry.io/otel/attribute/doc.go b/vendor/go.opentelemetry.io/otel/attribute/doc.go new file mode 100644 index 000000000..44bc32c9e --- /dev/null +++ b/vendor/go.opentelemetry.io/otel/attribute/doc.go @@ -0,0 +1,20 @@ +// Copyright The OpenTelemetry Authors +// +// Licensed under the Apache License, Version 2.0 (the "License"); +// you may not use this file except in compliance with the License. +// You may obtain a copy of the License at +// +// http://www.apache.org/licenses/LICENSE-2.0 +// +// Unless required by applicable law or agreed to in writing, software +// distributed under the License is distributed on an "AS IS" BASIS, +// WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. +// See the License for the specific language governing permissions and +// limitations under the License. + +// package attribute provides key and value attributes. +// +// This package is currently in a pre-GA phase.

Backwards incompatible changes +may be introduced in subsequent minor version releases as we work to track the +evolving OpenTelemetry specification and user feedback. + +Measurements can be made about an operation being performed or the state of a +system in general. These measurements can be crucial to the reliable operation +of code and provide valuable insights about the inner workings of a system. + +Measurements are made using instruments provided by this package. The type of +instrument used will depend on the type of measurement being made and of what +part of a system is being measured. + +Instruments are categorized as Synchronous or Asynchronous and independently +as Adding or Grouping. Synchronous instruments are called by the user with a +Context. Asynchronous instruments are called by the SDK during collection. +Additive instruments are semantically intended for capturing a sum. Grouping +instruments are intended for capturing a distribution. + +Additive instruments may be monotonic, in which case they are non-decreasing +and naturally define a rate. + +The synchronous instrument names are: + + Counter: additive, monotonic + UpDownCounter: additive + ValueRecorder: grouping + +and the asynchronous instruments are: + + SumObserver: additive, monotonic + UpDownSumObserver: additive + ValueObserver: grouping + +All instruments are provided with support for either float64 or int64 input +values. + +An instrument is created using a Meter. Additionally, a Meter is used to +record batches of synchronous measurements or asynchronous observations. A +Meter is obtained using a MeterProvider. A Meter, like a Tracer, is unique to +the instrumentation it instruments and must be named and versioned when +created with a MeterProvider with the name and version of the instrumentation +library. + +Instrumentation should be designed to accept a MeterProvider from which it can +create its own unique Meter. Alternatively, the registered global +MeterProvider from the go.opentelemetry.io/otel package can be used as a +default. +*/ +package metric // import "go.opentelemetry.io/otel/metric" diff --git a/vendor/go.opentelemetry.io/otel/metric/instrumentkind_string.go b/vendor/go.opentelemetry.io/otel/metric/instrumentkind_string.go new file mode 100644 index 000000000..2805e2250 --- /dev/null +++ b/vendor/go.opentelemetry.io/otel/metric/instrumentkind_string.go @@ -0,0 +1,28 @@ +// Code generated by "stringer -type=InstrumentKind"; DO NOT EDIT. + +package metric + +import "strconv" + +func _() { + // An "invalid array index" compiler error signifies that the constant values have changed. + // Re-run the stringer command to generate them again. + var x [1]struct{} + _ = x[ValueRecorderInstrumentKind-0] + _ = x[ValueObserverInstrumentKind-1] + _ = x[CounterInstrumentKind-2] + _ = x[UpDownCounterInstrumentKind-3] + _ = x[SumObserverInstrumentKind-4] + _ = x[UpDownSumObserverInstrumentKind-5] +} + +const _InstrumentKind_name = "ValueRecorderInstrumentKindValueObserverInstrumentKindCounterInstrumentKindUpDownCounterInstrumentKindSumObserverInstrumentKindUpDownSumObserverInstrumentKind" + +var _InstrumentKind_index = [...]uint8{0, 27, 54, 75, 102, 127, 158} + +func (i InstrumentKind) String() string { + if i < 0 || i >= InstrumentKind(len(_InstrumentKind_index)-1) { + return "InstrumentKind(" + strconv.FormatInt(int64(i), 10) + ")" + } + return _InstrumentKind_name[_InstrumentKind_index[i]:_InstrumentKind_index[i+1]] +} diff --git a/vendor/go.opentelemetry.io/otel/metric/metric.go b/vendor/go.opentelemetry.io/otel/metric/metric.go new file mode 100644 index 000000000..b591985df --- /dev/null +++ b/vendor/go.opentelemetry.io/otel/metric/metric.go @@ -0,0 +1,577 @@ +// Copyright The OpenTelemetry Authors +// +// Licensed under the Apache License, Version 2.0 (the "License"); +// you may not use this file except in compliance with the License. +// You may obtain a copy of the License at +// +// http://www.apache.org/licenses/LICENSE-2.0 +// +// Unless required by applicable law or agreed to in writing, software +// distributed under the License is distributed on an "AS IS" BASIS, +// WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. +// See the License for the specific language governing permissions and +// limitations under the License. + +package metric // import "go.opentelemetry.io/otel/metric" + +import ( + "context" + + "go.opentelemetry.io/otel/attribute" + "go.opentelemetry.io/otel/metric/number" + "go.opentelemetry.io/otel/unit" +) + +// MeterProvider supports named Meter instances. +type MeterProvider interface { + // Meter creates an implementation of the Meter interface. + // The instrumentationName must be the name of the library providing + // instrumentation.

Backwards incompatible changes +may be introduced in subsequent minor version releases as we work to track the +evolving OpenTelemetry specification and user feedback. + +The Accumulator type supports configurable metrics export behavior through a +collection of export interfaces that support various export strategies, +described below. + +The OpenTelemetry metric API consists of methods for constructing synchronous +and asynchronous instruments. There are two constructors per instrument for +the two kinds of number (int64, float64). + +Synchronous instruments are managed by a sync.Map containing a *record +with the current state for each synchronous instrument. A bound +instrument encapsulates a direct pointer to the record, allowing +bound metric events to bypass a sync.Map lookup. A lock-free +algorithm is used to protect against races when adding and removing +items from the sync.Map. + +Asynchronous instruments are managed by an internal +AsyncInstrumentState, which coordinates calling batch and single +instrument callbacks. + +Internal Structure + +Each observer also has its own kind of record stored in the SDK. This +record contains a set of recorders for every specific label set used in the +callback. + +A sync.Map maintains the mapping of current instruments and label sets to +internal records. To create a new bound instrument, the SDK consults the Map to +locate an existing record, otherwise it constructs a new record. The SDK +maintains a count of the number of references to each record, ensuring +that records are not reclaimed from the Map while they are still active +from the user's perspective. + +Metric collection is performed via a single-threaded call to Collect that +sweeps through all records in the SDK, checkpointing their state. When a +record is discovered that has no references and has not been updated since +the prior collection pass, it is removed from the Map. + +Both synchronous and asynchronous instruments have an associated +aggregator, which maintains the current state resulting from all metric +events since its last checkpoint. Aggregators may be lock-free or they may +use locking, but they should expect to be called concurrently. Aggregators +must be capable of merging with another aggregator of the same type. + +Export Pipeline + +While the SDK serves to maintain a current set of records and +coordinate collection, the behavior of a metrics export pipeline is +configured through the export types in +go.opentelemetry.io/otel/sdk/export/metric. It is important to keep +in mind the context these interfaces are called from. There are two +contexts, instrumentation context, where a user-level goroutine that +enters the SDK resulting in a new record, and collection context, +where a system-level thread performs a collection pass through the +SDK. + +Descriptor is a struct that describes the metric instrument to the +export pipeline, containing the name, units, description, metric kind, +number kind (int64 or float64). A Descriptor accompanies metric data +as it passes through the export pipeline. + +The AggregatorSelector interface supports choosing the method of +aggregation to apply to a particular instrument, by delegating the +construction of an Aggregator to this interface. Given the Descriptor, +the AggregatorFor method returns an implementation of Aggregator. If this +interface returns nil, the metric will be disabled. The aggregator should +be matched to the capabilities of the exporter. Selecting the aggregator +for Adding instruments is relatively straightforward, but many options +are available for aggregating distributions from Grouping instruments. + +Aggregator is an interface which implements a concrete strategy for +aggregating metric updates. Several Aggregator implementations are +provided by the SDK. Aggregators may be lock-free or use locking, +depending on their structure and semantics. Aggregators implement an +Update method, called in instrumentation context, to receive a single +metric event. Aggregators implement a Checkpoint method, called in +collection context, to save a checkpoint of the current state. +Aggregators implement a Merge method, also called in collection +context, that combines state from two aggregators into one. Each SDK +record has an associated aggregator. + +Processor is an interface which sits between the SDK and an exporter. +The Processor embeds an AggregatorSelector, used by the SDK to assign +new Aggregators. The Processor supports a Process() API for submitting +checkpointed aggregators to the processor, and a CheckpointSet() API +for producing a complete checkpoint for the exporter. Two default +Processor implementations are provided, the "defaultkeys" Processor groups +aggregate metrics by their recommended Descriptor.Keys(), the +"simple" Processor aggregates metrics at full dimensionality. + +LabelEncoder is an optional optimization that allows an exporter to +provide the serialization logic for labels. This allows avoiding +duplicate serialization of labels, once as a unique key in the SDK (or +Processor) and once in the exporter. + +CheckpointSet is an interface between the Processor and the Exporter. +After completing a collection pass, the Processor.CheckpointSet() method +returns a CheckpointSet, which the Exporter uses to iterate over all +the updated metrics. + +Record is a struct containing the state of an individual exported +metric. This is the result of one collection interface for one +instrument and one label set. + +Labels is a struct containing an ordered set of labels, the +corresponding unique encoding, and the encoder that produced it. + +Exporter is the final stage of an export pipeline. It is called with +a CheckpointSet capable of enumerating all the updated metrics. + +Controller is not an export interface per se, but it orchestrates the +export pipeline. For example, a "push" controller will establish a +periodic timer to regularly collect and export metrics. A "pull" +controller will await a pull request before initiating metric +collection. Either way, the job of the controller is to call the SDK +Collect() method, then read the checkpoint, then invoke the exporter. +Controllers are expected to implement the public metric.MeterProvider +API, meaning they can be installed as the global Meter provider. + +*/ +package metric // import "go.opentelemetry.io/otel/sdk/metric" diff --git a/vendor/go.opentelemetry.io/otel/sdk/metric/processor/basic/basic.go b/vendor/go.opentelemetry.io/otel/sdk/metric/processor/basic/basic.go new file mode 100644 index 000000000..39d1972dc --- /dev/null +++ b/vendor/go.opentelemetry.io/otel/sdk/metric/processor/basic/basic.go @@ -0,0 +1,377 @@ +// Copyright The OpenTelemetry Authors +// +// Licensed under the Apache License, Version 2.0 (the "License"); +// you may not use this file except in compliance with the License. +// You may obtain a copy of the License at +// +// http://www.apache.org/licenses/LICENSE-2.0 +// +// Unless required by applicable law or agreed to in writing, software +// distributed under the License is distributed on an "AS IS" BASIS, +// WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. +// See the License for the specific language governing permissions and +// limitations under the License. + +package basic // import "go.opentelemetry.io/otel/sdk/metric/processor/basic" + +import ( + "errors" + "fmt" + "sync" + "time" + + "go.opentelemetry.io/otel/attribute" + "go.opentelemetry.io/otel/metric" + export "go.opentelemetry.io/otel/sdk/export/metric" + "go.opentelemetry.io/otel/sdk/export/metric/aggregation" + "go.opentelemetry.io/otel/sdk/resource" +) + +type ( + Processor struct { + export.ExportKindSelector + export.AggregatorSelector + + state + } + + stateKey struct { + // TODO: This code is organized to support multiple + // accumulators which could theoretically produce the + // data for the same instrument with the same + // resources, and this code has logic to combine data + // properly from multiple accumulators.

It allows developers to build a single API service +// that supports both gRPC APIs and REST APIs. Many systems, including [Google +// APIs](https://github.com/googleapis/googleapis), +// [Cloud Endpoints](https://cloud.google.com/endpoints), [gRPC +// Gateway](https://github.com/grpc-ecosystem/grpc-gateway), +// and [Envoy](https://github.com/envoyproxy/envoy) proxy support this feature +// and use it for large scale production services. +// +// `HttpRule` defines the schema of the gRPC/REST mapping. The mapping specifies +// how different portions of the gRPC request message are mapped to the URL +// path, URL query parameters, and HTTP request body. It also controls how the +// gRPC response message is mapped to the HTTP response body. `HttpRule` is +// typically specified as an `google.api.http` annotation on the gRPC method. +// +// Each mapping specifies a URL path template and an HTTP method. The path +// template may refer to one or more fields in the gRPC request message, as long +// as each field is a non-repeated field with a primitive (non-message) type. +// The path template controls how fields of the request message are mapped to +// the URL path. +// +// Example: +// +// service Messaging { +// rpc GetMessage(GetMessageRequest) returns (Message) { +// option (google.api.http) = { +// get: "/v1/{name=messages/*}" +// }; +// } +// } +// message GetMessageRequest { +// string name = 1; // Mapped to URL path. +// } +// message Message { +// string text = 1; // The resource content. +// } +// +// This enables an HTTP REST to gRPC mapping as below: +// +// HTTP | gRPC +// -----|----- +// `GET /v1/messages/123456` | `GetMessage(name: "messages/123456")` +// +// Any fields in the request message which are not bound by the path template +// automatically become HTTP query parameters if there is no HTTP request body. +// For example: +// +// service Messaging { +// rpc GetMessage(GetMessageRequest) returns (Message) { +// option (google.api.http) = { +// get:"/v1/messages/{message_id}" +// }; +// } +// } +// message GetMessageRequest { +// message SubMessage { +// string subfield = 1; +// } +// string message_id = 1; // Mapped to URL path. +// int64 revision = 2; // Mapped to URL query parameter `revision`. +// SubMessage sub = 3; // Mapped to URL query parameter `sub.subfield`. +// } +// +// This enables a HTTP JSON to RPC mapping as below: +// +// HTTP | gRPC +// -----|----- +// `GET /v1/messages/123456?revision=2&sub.subfield=foo` | +// `GetMessage(message_id: "123456" revision: 2 sub: SubMessage(subfield: +// "foo"))` +// +// Note that fields which are mapped to URL query parameters must have a +// primitive type or a repeated primitive type or a non-repeated message type. +// In the case of a repeated type, the parameter can be repeated in the URL +// as `...?param=A¶m=B`. In the case of a message type, each field of the +// message is mapped to a separate parameter, such as +// `...?foo.a=A&foo.b=B&foo.c=C`. +// +// For HTTP methods that allow a request body, the `body` field +// specifies the mapping. Consider a REST update method on the +// message resource collection: +// +// service Messaging { +// rpc UpdateMessage(UpdateMessageRequest) returns (Message) { +// option (google.api.http) = { +// patch: "/v1/messages/{message_id}" +// body: "message" +// }; +// } +// } +// message UpdateMessageRequest { +// string message_id = 1; // mapped to the URL +// Message message = 2; // mapped to the body +// } +// +// The following HTTP JSON to RPC mapping is enabled, where the +// representation of the JSON in the request body is determined by +// protos JSON encoding: +// +// HTTP | gRPC +// -----|----- +// `PATCH /v1/messages/123456 { "text": "Hi!" }` | `UpdateMessage(message_id: +// "123456" message { text: "Hi!" })` +// +// The special name `*` can be used in the body mapping to define that +// every field not bound by the path template should be mapped to the +// request body. This enables the following alternative definition of +// the update method: +// +// service Messaging { +// rpc UpdateMessage(Message) returns (Message) { +// option (google.api.http) = { +// patch: "/v1/messages/{message_id}" +// body: "*" +// }; +// } +// } +// message Message { +// string message_id = 1; +// string text = 2; +// } +// +// +// The following HTTP JSON to RPC mapping is enabled: +// +// HTTP | gRPC +// -----|----- +// `PATCH /v1/messages/123456 { "text": "Hi!" }` | `UpdateMessage(message_id: +// "123456" text: "Hi!")` +// +// Note that when using `*` in the body mapping, it is not possible to +// have HTTP parameters, as all fields not bound by the path end in +// the body. This makes this option more rarely used in practice when +// defining REST APIs. The common usage of `*` is in custom methods +// which don't use the URL at all for transferring data. +// +// It is possible to define multiple HTTP methods for one RPC by using +// the `additional_bindings` option. Example: +// +// service Messaging { +// rpc GetMessage(GetMessageRequest) returns (Message) { +// option (google.api.http) = { +// get: "/v1/messages/{message_id}" +// additional_bindings { +// get: "/v1/users/{user_id}/messages/{message_id}" +// } +// }; +// } +// } +// message GetMessageRequest { +// string message_id = 1; +// string user_id = 2; +// } +// +// This enables the following two alternative HTTP JSON to RPC mappings: +// +// HTTP | gRPC +// -----|----- +// `GET /v1/messages/123456` | `GetMessage(message_id: "123456")` +// `GET /v1/users/me/messages/123456` | `GetMessage(user_id: "me" message_id: +// "123456")` +// +// ## Rules for HTTP mapping +// +// 1. Leaf request fields (recursive expansion nested messages in the request +// message) are classified into three categories: +// - Fields referred by the path template. They are passed via the URL path. +// - Fields referred by the [HttpRule.body][google.api.HttpRule.body]. They are passed via the HTTP +// request body. +// - All other fields are passed via the URL query parameters, and the +// parameter name is the field path in the request message. A repeated +// field can be represented as multiple query parameters under the same +// name. +// 2. If [HttpRule.body][google.api.HttpRule.body] is "*", there is no URL query parameter, all fields +// are passed via URL path and HTTP request body. +// 3. If [HttpRule.body][google.api.HttpRule.body] is omitted, there is no HTTP request body, all +// fields are passed via URL path and URL query parameters. +// +// ### Path template syntax +// +// Template = "/" Segments [ Verb ] ; +// Segments = Segment { "/" Segment } ; +// Segment = "*" | "**" | LITERAL | Variable ; +// Variable = "{" FieldPath [ "=" Segments ] "}" ; +// FieldPath = IDENT { "." IDENT } ; +// Verb = ":" LITERAL ; +// +// The syntax `*` matches a single URL path segment. The syntax `**` matches +// zero or more URL path segments, which must be the last part of the URL path +// except the `Verb`. +// +// The syntax `Variable` matches part of the URL path as specified by its +// template. A variable template must not contain other variables. If a variable +// matches a single path segment, its template may be omitted, e.g. `{var}` +// is equivalent to `{var=*}`. +// +// The syntax `LITERAL` matches literal text in the URL path. If the `LITERAL` +// contains any reserved character, such characters should be percent-encoded +// before the matching. +// +// If a variable contains exactly one path segment, such as `"{var}"` or +// `"{var=*}"`, when such a variable is expanded into a URL path on the client +// side, all characters except `[-_.~0-9a-zA-Z]` are percent-encoded. The +// server side does the reverse decoding. Such variables show up in the +// [Discovery +// Document](https://developers.google.com/discovery/v1/reference/apis) as +// `{var}`. +// +// If a variable contains multiple path segments, such as `"{var=foo/*}"` +// or `"{var=**}"`, when such a variable is expanded into a URL path on the +// client side, all characters except `[-_.~/0-9a-zA-Z]` are percent-encoded. +// The server side does the reverse decoding, except "%2F" and "%2f" are left +// unchanged. Such variables show up in the +// [Discovery +// Document](https://developers.google.com/discovery/v1/reference/apis) as +// `{+var}`. +// +// ## Using gRPC API Service Configuration +// +// gRPC API Service Configuration (service config) is a configuration language +// for configuring a gRPC service to become a user-facing product. The +// service config is simply the YAML representation of the `google.api.Service` +// proto message. +// +// As an alternative to annotating your proto file, you can configure gRPC +// transcoding in your service config YAML files. You do this by specifying a +// `HttpRule` that maps the gRPC method to a REST endpoint, achieving the same +// effect as the proto annotation. This can be particularly useful if you +// have a proto that is reused in multiple services. Note that any transcoding +// specified in the service config will override any matching transcoding +// configuration in the proto. +// +// Example: +// +// http: +// rules: +// # Selects a gRPC method and applies HttpRule to it. +// - selector: example.v1.Messaging.GetMessage +// get: /v1/messages/{message_id}/{sub.subfield} +// +// ## Special notes +// +// When gRPC Transcoding is used to map a gRPC to JSON REST endpoints, the +// proto to JSON conversion must follow the [proto3 +// specification](https://developers.google.com/protocol-buffers/docs/proto3#json). +// +// While the single segment variable follows the semantics of +// [RFC 6570](https://tools.ietf.org/html/rfc6570) Section 3.2.2 Simple String +// Expansion, the multi segment variable **does not** follow RFC 6570 Section +// 3.2.3 Reserved Expansion. The reason is that the Reserved Expansion +// does not expand special characters like `?` and `#`, which would lead +// to invalid URLs. As the result, gRPC Transcoding uses a custom encoding +// for multi segment variables. +// +// The path variables **must not** refer to any repeated or mapped field, +// because client libraries are not capable of handling such variable expansion. +// +// The path variables **must not** capture the leading "/" character. The reason +// is that the most common use case "{var}" does not capture the leading "/" +// character. For consistency, all path variables must share the same behavior. +// +// Repeated message fields must not be mapped to URL query parameters, because +// no client library can support such complicated mapping. +// +// If an API needs to use a JSON array for request or response body, it can map +// the request or response body to a repeated field. However, some gRPC +// Transcoding implementations may not support this feature. +type HttpRule struct { + state protoimpl.MessageState + sizeCache protoimpl.SizeCache + unknownFields protoimpl.UnknownFields + + // Selects a method to which this rule applies. + // + // Refer to [selector][google.api.DocumentationRule.selector] for syntax details. + Selector string `protobuf:"bytes,1,opt,name=selector,proto3" json:"selector,omitempty"` + // Determines the URL pattern is matched by this rules.

For example, if the mask in the previous +// example is applied to a response message as follows: +// +// f { +// a : 22 +// b { +// d : 1 +// x : 2 +// } +// y : 13 +// } +// z: 8 +// +// The result will not contain specific values for fields x,y and z +// (their value will be set to the default, and omitted in proto text +// output): +// +// +// f { +// a : 22 +// b { +// d : 1 +// } +// } +// +// A repeated field is not allowed except at the last position of a +// paths string. +// +// If a FieldMask object is not present in a get operation, the +// operation applies to all fields (as if a FieldMask of all fields +// had been specified). +// +// Note that a field mask does not necessarily apply to the +// top-level response message. In case of a REST get operation, the +// field mask applies directly to the response, but in case of a REST +// list operation, the mask instead applies to each individual message +// in the returned resource list. In case of a REST custom method, +// other definitions may be used. Where the mask applies will be +// clearly documented together with its declaration in the API. In +// any case, the effect on the returned resource/resources is required +// behavior for APIs. +// +// # Field Masks in Update Operations +// +// A field mask in update operations specifies which fields of the +// targeted resource are going to be updated. The API is required +// to only change the values of the fields as specified in the mask +// and leave the others untouched. If a resource is passed in to +// describe the updated values, the API ignores the values of all +// fields not covered by the mask. +// +// If a repeated field is specified for an update operation, new values will +// be appended to the existing repeated field in the target resource. Note that +// a repeated field is only allowed in the last position of a `paths` string. +// +// If a sub-message is specified in the last position of the field mask for an +// update operation, then new value will be merged into the existing sub-message +// in the target resource. +// +// For example, given the target message: +// +// f { +// b { +// d: 1 +// x: 2 +// } +// c: [1] +// } +// +// And an update message: +// +// f { +// b { +// d: 10 +// } +// c: [2] +// } +// +// then if the field mask is: +// +// paths: ["f.b", "f.c"] +// +// then the result will be: +// +// f { +// b { +// d: 10 +// x: 2 +// } +// c: [1, 2] +// } +// +// An implementation may provide options to override this default behavior for +// repeated and message fields. +// +// In order to reset a field's value to the default, the field must +// be in the mask and set to the default value in the provided resource. +// Hence, in order to reset all fields of a resource, provide a default +// instance of the resource and set all fields in the mask, or do +// not provide a mask as described below. +// +// If a field mask is not present on update, the operation applies to +// all fields (as if a field mask of all fields has been specified). +// Note that in the presence of schema evolution, this may mean that +// fields the client does not know and has therefore not filled into +// the request will be reset to their default. If this is unwanted +// behavior, a specific service may require a client to always specify +// a field mask, producing an error if not. +// +// As with get operations, the location of the resource which +// describes the updated values in the request message depends on the +// operation kind. In any case, the effect of the field mask is +// required to be honored by the API. +// +// ## Considerations for HTTP REST +// +// The HTTP kind of an update operation which uses a field mask must +// be set to PATCH instead of PUT in order to satisfy HTTP semantics +// (PUT must only be used for full updates). +// +// # JSON Encoding of Field Masks +// +// In JSON, a field mask is encoded as a single string where paths are +// separated by a comma. Fields name in each path are converted +// to/from lower-camel naming conventions. +// +// As an example, consider the following message declarations: +// +// message Profile { +// User user = 1; +// Photo photo = 2; +// } +// message User { +// string display_name = 1; +// string address = 2; +// } +// +// In proto a field mask for `Profile` may look as such: +// +// mask { +// paths: "user.display_name" +// paths: "photo" +// } +// +// In JSON, the same mask is represented as below: +// +// { +// mask: "user.displayName,photo" +// } +// +// # Field Masks and Oneof Fields +// +// Field masks treat fields in oneofs just as regular fields. Consider the +// following message: +// +// message SampleMessage { +// oneof test_oneof { +// string name = 4; +// SubMessage sub_message = 9; +// } +// } +// +// The field mask can be: +// +// mask { +// paths: "name" +// } +// +// Or: +// +// mask { +// paths: "sub_message" +// } +// +// Note that oneof type names ("test_oneof" in this case) cannot be used in +// paths. +// +// ## Field Mask Verification +// +// The implementation of any API method which has a FieldMask type field in the +// request should verify the included field paths, and return an +// `INVALID_ARGUMENT` error if any path is unmappable. +type FieldMask struct { + state protoimpl.MessageState + sizeCache protoimpl.SizeCache + unknownFields protoimpl.UnknownFields + + // The set of field mask paths. + Paths []string `protobuf:"bytes,1,rep,name=paths,proto3" json:"paths,omitempty"` +} + +// New constructs a field mask from a list of paths and verifies that +// each one is valid according to the specified message type. +func New(m proto.Message, paths ...string) (*FieldMask, error) { + x := new(FieldMask) + return x, x.Append(m, paths...) +} + +// Union returns the union of all the paths in the input field masks. +func Union(mx *FieldMask, my *FieldMask, ms ...*FieldMask) *FieldMask { + var out []string + out = append(out, mx.GetPaths()...) + out = append(out, my.GetPaths()...) + for _, m := range ms { + out = append(out, m.GetPaths()...) + } + return &FieldMask{Paths: normalizePaths(out)} +} + +// Intersect returns the intersection of all the paths in the input field masks. +func Intersect(mx *FieldMask, my *FieldMask, ms ...*FieldMask) *FieldMask { + var ss1, ss2 []string // reused buffers for performance + intersect := func(out, in []string) []string { + ss1 = normalizePaths(append(ss1[:0], in...)) + ss2 = normalizePaths(append(ss2[:0], out...)) + out = out[:0] + for i1, i2 := 0, 0;

Backup log files will be retained + // in the same directory. It uses -lumberjack.log in + // os.TempDir() if empty. + Filename string `json:"filename" yaml:"filename"` + + // MaxSize is the maximum size in megabytes of the log file before it gets + // rotated. It defaults to 100 megabytes. + MaxSize int `json:"maxsize" yaml:"maxsize"` + + // MaxAge is the maximum number of days to retain old log files based on the + // timestamp encoded in their filename. Note that a day is defined as 24 + // hours and may not exactly correspond to calendar days due to daylight + // savings, leap seconds, etc. The default is not to remove old log files + // based on age. + MaxAge int `json:"maxage" yaml:"maxage"` + + // MaxBackups is the maximum number of old log files to retain. The default + // is to retain all old log files (though MaxAge may still cause them to get + // deleted.) + MaxBackups int `json:"maxbackups" yaml:"maxbackups"` + + // LocalTime determines if the time used for formatting the timestamps in + // backup files is the computer's local time. The default is to use UTC + // time. + LocalTime bool `json:"localtime" yaml:"localtime"` + + // Compress determines if the rotated log files should be compressed + // using gzip. The default is not to perform compression. + Compress bool `json:"compress" yaml:"compress"` + // contains filtered or unexported fields +} +``` +Logger is an io.WriteCloser that writes to the specified filename. + +Logger opens or creates the logfile on first Write. If the file exists and +is less than MaxSize megabytes, lumberjack will open and append to that file. +If the file exists and its size is >= MaxSize megabytes, the file is renamed +by putting the current time in a timestamp in the name immediately before the +file's extension (or the end of the filename if there's no extension). A new +log file is then created using original filename. + +Whenever a write would cause the current log file exceed MaxSize megabytes, +the current file is closed, renamed, and a new log file created with the +original name. Thus, the filename you give Logger is always the "current" log +file. + +Backups use the log file name given to Logger, in the form `name-timestamp.ext` +where name is the filename without the extension, timestamp is the time at which +the log was rotated formatted with the time.Time format of +`2006-01-02T15-04-05.000` and the extension is the original extension. For +example, if your Logger.Filename is `/var/log/foo/server.log`, a backup created +at 6:30pm on Nov 11 2016 would use the filename +`/var/log/foo/server-2016-11-04T18-30-00.000.log` + +### Cleaning Up Old Log Files +Whenever a new logfile gets created, old log files may be deleted. The most +recent files according to the encoded timestamp will be retained, up to a +number equal to MaxBackups (or all of them if MaxBackups is 0). Any files +with an encoded timestamp older than MaxAge days are deleted, regardless of +MaxBackups. Note that the time encoded in the timestamp is the rotation +time, which may differ from the last time that file was written to. + +If MaxBackups and MaxAge are both 0, no old log files will be deleted. + + + + + + + + + + + +### func (\*Logger) Close +``` go +func (l *Logger) Close() error +``` +Close implements io.Closer, and closes the current logfile. + + + +### func (\*Logger) Rotate +``` go +func (l *Logger) Rotate() error +``` +Rotate causes Logger to close the existing log file and immediately create a +new one.
