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.

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-jones-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.

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. + +## 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/dgrijalva/jwt-go/VERSION_HISTORY.md b/vendor/github.com/dgrijalva/jwt-go/VERSION_HISTORY.md new file mode 100644 index 000000000..637029831 --- /dev/null +++ b/vendor/github.com/dgrijalva/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`.

Go](https://github.com/grpc/grpc-go) Middleware: interceptors, helpers, utilities. + +## Middleware + +[gRPC Go](https://github.com/grpc/grpc-go) recently acquired support for +Interceptors, i.e. [middleware](https://medium.com/@matryer/writing-middleware-in-golang-and-how-go-makes-it-so-much-fun-4375c1246e81#.gv7tdlghs) +that is executed either on the gRPC Server before the request is passed onto the user's application logic, or on the gRPC client either around the user call. It is a perfect way to implement +common patterns: auth, logging, message, validation, retries or monitoring. + +These are generic building blocks that make it easy to build multiple microservices easily. +The purpose of this repository is to act as a go-to point for such reusable functionality. It contains +some of them itself, but also will link to useful external repos. + +`grpc_middleware` itself provides support for chaining interceptors, here's an example: + +```go +import "github.com/grpc-ecosystem/go-grpc-middleware" + +myServer := grpc.NewServer( + grpc.StreamInterceptor(grpc_middleware.ChainStreamServer( + grpc_ctxtags.StreamServerInterceptor(), + grpc_opentracing.StreamServerInterceptor(), + grpc_prometheus.StreamServerInterceptor, + grpc_zap.StreamServerInterceptor(zapLogger), + grpc_auth.StreamServerInterceptor(myAuthFunction), + grpc_recovery.StreamServerInterceptor(), + )), + grpc.UnaryInterceptor(grpc_middleware.ChainUnaryServer( + grpc_ctxtags.UnaryServerInterceptor(), + grpc_opentracing.UnaryServerInterceptor(), + grpc_prometheus.UnaryServerInterceptor, + grpc_zap.UnaryServerInterceptor(zapLogger), + grpc_auth.UnaryServerInterceptor(myAuthFunction), + grpc_recovery.UnaryServerInterceptor(), + )), +) +``` + +## Interceptors + +*Please send a PR to add new interceptors or middleware to this list* + +#### Auth + * [`grpc_auth`](auth) - a customizable (via `AuthFunc`) piece of auth middleware + +#### Logging + * [`grpc_ctxtags`](tags/) - a library that adds a `Tag` map to context, with data populated from request body + * [`grpc_zap`](logging/zap/) - integration of [zap](https://github.com/uber-go/zap) logging library into gRPC handlers. + * [`grpc_logrus`](logging/logrus/) - integration of [logrus](https://github.com/sirupsen/logrus) logging library into gRPC handlers. + + +#### Monitoring + * [`grpc_prometheus`⚡](https://github.com/grpc-ecosystem/go-grpc-prometheus) - Prometheus client-side and server-side monitoring middleware + * [`otgrpc`⚡](https://github.com/grpc-ecosystem/grpc-opentracing/tree/master/go/otgrpc) - [OpenTracing](http://opentracing.io/) client-side and server-side interceptors + * [`grpc_opentracing`](tracing/opentracing) - [OpenTracing](http://opentracing.io/) client-side and server-side interceptors with support for streaming and handler-returned tags + +#### Client + * [`grpc_retry`](retry/) - a generic gRPC response code retry mechanism, client-side middleware + +#### Server + * [`grpc_validator`](validator/) - codegen inbound message validation from `.proto` options + * [`grpc_recovery`](recovery/) - turn panics into gRPC errors + + +## Status + +This code has been running in *production* since May 2016 as the basis of the gRPC micro services stack at [Improbable](https://improbable.io). + +Additional tooling will be added, and contributions are welcome. + +## License + +`go-grpc-middleware` is released under the Apache 2.0 license.

This package provides monitoring Interceptors for both. + +### Server-side + +```go +import "github.com/grpc-ecosystem/go-grpc-prometheus" +... + // Initialize your gRPC server's interceptor. + myServer := grpc.NewServer( + grpc.StreamInterceptor(grpc_prometheus.StreamServerInterceptor), + grpc.UnaryInterceptor(grpc_prometheus.UnaryServerInterceptor), + ) + // Register your gRPC service implementations. + myservice.RegisterMyServiceServer(s.server, &myServiceImpl{}) + // After all your registrations, make sure all of the Prometheus metrics are initialized. + grpc_prometheus.Register(myServer) + // Register Prometheus metrics handler. + http.Handle("/metrics", promhttp.Handler()) +... +``` + +### Client-side + +```go +import "github.com/grpc-ecosystem/go-grpc-prometheus" +... + clientConn, err = grpc.Dial( + address, + grpc.WithUnaryInterceptor(grpc_prometheus.UnaryClientInterceptor), + grpc.WithStreamInterceptor(grpc_prometheus.StreamClientInterceptor) + ) + client = pb_testproto.NewTestServiceClient(clientConn) + resp, err := client.PingEmpty(s.ctx, &myservice.Request{Msg: "hello"}) +... +``` + +# Metrics + +## Labels + +All server-side metrics start with `grpc_server` as Prometheus subsystem name. 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. Please note +how the `grpc_method` is being omitted here: all methods of a given gRPC service will be summed together. + +### unary request error rate +```jsoniq +sum(rate(grpc_server_handled_total{job="foo",grpc_type="unary",grpc_code!="OK"}[1m])) by (grpc_service) +``` +For `job="foo"`, calculate the per-`grpc_service` rate of `unary` (1:1) RPCs that failed, i.e. the +ones that didn't finish with `OK` code. + +### unary request error percentage +```jsoniq +sum(rate(grpc_server_handled_total{job="foo",grpc_type="unary",grpc_code!="OK"}[1m])) by (grpc_service) + / +sum(rate(grpc_server_started_total{job="foo",grpc_type="unary"}[1m])) by (grpc_service) + * 100.0 +``` +For `job="foo"`, calculate the percentage of failed requests by service. It's easy to notice that +this is a combination of the two above examples. This is an example of a query you would like to +[alert on](https://prometheus.io/docs/alerting/rules/) in your system for SLA violations, e.g. +"no more than 1% requests should fail". + +### average response stream size +```jsoniq +sum(rate(grpc_server_msg_sent_total{job="foo",grpc_type="server_stream"}[10m])) by (grpc_service) + / +sum(rate(grpc_server_started_total{job="foo",grpc_type="server_stream"}[10m])) by (grpc_service) +``` +For `job="foo"` what is the `grpc_service`-wide `10m` average of messages returned for all ` +server_stream` RPCs. This allows you to track the stream sizes returned by your system, e.g. allows +you to track when clients started to send "wide" queries that ret +Note the divisor is the number of started RPCs, in order to account for in-flight requests. + +### 99%-tile latency of unary requests +```jsoniq +histogram_quantile(0.99, + sum(rate(grpc_server_handling_seconds_bucket{job="foo",grpc_type="unary"}[5m])) by (grpc_service,le) +) +``` +For `job="foo"`, returns an 99%-tile [quantile estimation](https://prometheus.io/docs/practices/histograms/#quantiles) +of the handling time of RPCs per service. Please note the `5m` rate, this means that the quantile +estimation will take samples in a rolling `5m` window. When combined with other quantiles +(e.g. 50%, 90%), this query gives you tremendous insight into the responsiveness of your system +(e.g. impact of caching). + +### percentage of slow unary queries (>250ms) +```jsoniq +100.0 - ( +sum(rate(grpc_server_handling_seconds_bucket{job="foo",grpc_type="unary",le="0.25"}[5m])) by (grpc_service) + / +sum(rate(grpc_server_handling_seconds_count{job="foo",grpc_type="unary"}[5m])) by (grpc_service) +) * 100.0 +``` +For `job="foo"` calculate the by-`grpc_service` fraction of slow requests that took longer than `0.25` +seconds. This query is relatively complex, since the Prometheus aggregations use `le` (less or equal) +buckets, meaning that counting "fast" requests fractions is easier. However, simple maths helps. +This is an example of a query you would like to alert on in your system for SLA violations, +e.g. "less than 1% of requests are slower than 250ms". + + +## Status + +This code has been used since August 2015 as the basis for monitoring of *production* gRPC micro services at [Improbable](https://improbable.io). + +## License + +`go-grpc-prometheus` is released under the Apache 2.0 license.

Use it at your own risk. + +[![GoDoc](https://godoc.org/github.com/prometheus/procfs?status.png)](https://godoc.org/github.com/prometheus/procfs) +[![Build Status](https://travis-ci.org/prometheus/procfs.svg?branch=master)](https://travis-ci.org/prometheus/procfs) +[![Go Report Card](https://goreportcard.com/badge/github.com/prometheus/procfs)](https://goreportcard.com/report/github.com/prometheus/procfs) + +## Usage + +The procfs library is organized by packages based on whether the gathered data is coming from +/proc, /sys, or both. Each package contains an `FS` type which represents the path to either /proc, /sys, or both. For example, current 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() +``` + +## Building and Testing + +The procfs library is normally built as part of another application. However, when making +changes to the library, the `make test` command can be used to run the API test suite. + +### 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/fixtures.ttar b/vendor/github.com/prometheus/procfs/fixtures.ttar new file mode 100644 index 000000000..951d909af --- /dev/null +++ b/vendor/github.com/prometheus/procfs/fixtures.ttar @@ -0,0 +1,1808 @@ +# Archive created by ttar -c -f fixtures.ttar fixtures/ +Directory: fixtures +Mode: 775 +# ttar -

Status](https://travis-ci.org/sirupsen/logrus.svg?branch=master)](https://travis-ci.org/sirupsen/logrus) [![GoDoc](https://godoc.org/github.com/sirupsen/logrus?status.svg)](https://godoc.org/github.com/sirupsen/logrus) + +Logrus is a structured logger for Go (golang), completely API compatible with +the standard library logger. + +**Seeing weird case-sensitive problems?** It's in the past been possible to +import Logrus as both upper- and lower-case. Due to the Go package environment, +this caused issues in the community and we needed a standard. Some environments +experienced problems with the upper-case variant, so the lower-case was decided. +Everything using `logrus` will need to use the lower-case: +`github.com/sirupsen/logrus`. Any package that isn't, should be changed. + +To fix Glide, see [these +comments](https://github.com/sirupsen/logrus/issues/553#issuecomment-306591437). +For an in-depth explanation of the casing issue, see [this +comment](https://github.com/sirupsen/logrus/issues/570#issuecomment-313933276). + +**Are you interested in assisting in maintaining Logrus?** Currently I have a +lot of obligations, and I am unable to provide Logrus with the maintainership it +needs. If you'd like to help, please reach out to me at `simon at author's +username dot com`. + +Nicely color-coded in development (when a TTY is attached, otherwise just +plain text): + +![Colored](http://i.imgur.com/PY7qMwd.png) + +With `log.SetFormatter(&log.JSONFormatter{})`, for easy parsing by logstash +or Splunk: + +```json +{"animal":"walrus","level":"info","msg":"A group of walrus emerges from the +ocean","size":10,"time":"2014-03-10 19:57:38.562264131 -0400 EDT"} + +{"level":"warning","msg":"The group's number increased tremendously!", +"number":122,"omg":true,"time":"2014-03-10 19:57:38.562471297 -0400 EDT"} + +{"animal":"walrus","level":"info","msg":"A giant walrus appears!", +"size":10,"time":"2014-03-10 19:57:38.562500591 -0400 EDT"} + +{"animal":"walrus","level":"info","msg":"Tremendously sized cow enters the ocean.", +"size":9,"time":"2014-03-10 19:57:38.562527896 -0400 EDT"} + +{"level":"fatal","msg":"The ice breaks!","number":100,"omg":true, +"time":"2014-03-10 19:57:38.562543128 -0400 EDT"} +``` + +With the default `log.SetFormatter(&log.TextFormatter{})` when a TTY is not +attached, the output is compatible with the +[logfmt](http://godoc.org/github.com/kr/logfmt) format: + +```text +time="2015-03-26T01:27:38-04:00" level=debug msg="Started observing beach" animal=walrus number=8 +time="2015-03-26T01:27:38-04:00" level=info msg="A group of walrus emerges from the ocean" animal=walrus size=10 +time="2015-03-26T01:27:38-04:00" level=warning msg="The group's number increased tremendously!" number=122 omg=true +time="2015-03-26T01:27:38-04:00" level=debug msg="Temperature changes" temperature=-4 +time="2015-03-26T01:27:38-04:00" level=panic msg="It's over 9000!" animal=orca size=9009 +time="2015-03-26T01:27:38-04:00" level=fatal msg="The ice breaks!" err=&{0x2082280c0 map[animal:orca size:9009] 2015-03-26 01:27:38.441574009 -0400 EDT panic It's over 9000!} number=100 omg=true +``` +To ensure this behaviour even if a TTY is attached, set your formatter as follows: + +```go + log.SetFormatter(&log.TextFormatter{ + DisableColors: true, + FullTimestamp: true, + }) +``` + +#### Logging Method Name + +If you wish to add the calling method as a field, instruct the logger via: +```go +log.SetReportCaller(true) +``` +This adds the caller as 'method' like so: + +```json +{"animal":"penguin","level":"fatal","method":"github.com/sirupsen/arcticcreatures.migrate","msg":"a penguin swims by", +"time":"2014-03-10 19:57:38.562543129 -0400 EDT"} +``` + +```text +time="2015-03-26T01:27:38-04:00" level=fatal method=github.com/sirupsen/arcticcreatures.migrate msg="a penguin swims by" animal=penguin +``` +Note that this does add measurable overhead - the cost will depend on the version of Go, but is +between 20 and 40% in recent tests with 1.6 and 1.7. You can validate this in your +environment via benchmarks: +``` +go test -bench=.*CallerTracing +``` + + +#### Case-sensitivity + +The organization's name was changed to lower-case--and this will not be changed +back. If you are getting import conflicts due to case sensitivity, please use +the lower-case import: `github.com/sirupsen/logrus`. + +#### Example + +The simplest way to use Logrus is simply the package-level exported logger: + +```go +package main + +import ( + log "github.com/sirupsen/logrus" +) + +func main() { + log.WithFields(log.Fields{ + "animal": "walrus", + }).Info("A walrus appears") +} +``` + +Note that it's completely api-compatible with the stdlib logger, so you can +replace your `log` imports everywhere with `log "github.com/sirupsen/logrus"` +and you'll now have the flexibility of Logrus. You can customize it all you +want: + +```go +package main + +import ( + "os" + log "github.com/sirupsen/logrus" +) + +func init() { + // Log as JSON instead of the default ASCII formatter. + log.SetFormatter(&log.JSONFormatter{}) + + // Output to stdout instead of the default stderr + // Can be any io.Writer, see below for File example + log.SetOutput(os.Stdout) + + // Only log the warning severity or above. + log.SetLevel(log.WarnLevel) +} + +func main() { + log.WithFields(log.Fields{ + "animal": "walrus", + "size": 10, + }).Info("A group of walrus emerges from the ocean") + + log.WithFields(log.Fields{ + "omg": true, + "number": 122, + }).Warn("The group's number increased tremendously!") + + log.WithFields(log.Fields{ + "omg": true, + "number": 100, + }).Fatal("The ice breaks!") + + // A common pattern is to re-use fields between logging statements by re-using + // the logrus.Entry returned from WithFields() + contextLogger := log.WithFields(log.Fields{ + "common": "this is a common field", + "other": "I also should be logged always", + }) + + contextLogger.Info("I'll be logged with common and other field") + contextLogger.Info("Me too") +} +``` + +For more advanced usage such as logging to multiple locations from the same +application, you can also create an instance of the `logrus` Logger: + +```go +package main + +import ( + "os" + "github.com/sirupsen/logrus" +) + +// Create a new instance of the logger. You can have any number of instances. +var log = logrus.New() + +func main() { + // The API for setting attributes is a little different than the package level + // exported logger. See Godoc. + log.Out = os.Stdout + + // You could set this to any `io.Writer` such as a file + // file, err := os.OpenFile("logrus.log", os.O_CREATE|os.O_WRONLY, 0666) + // if err == nil { + // log.Out = file + // } else { + // log.Info("Failed to log to file, using default stderr") + // } + + log.WithFields(logrus.Fields{ + "animal": "walrus", + "size": 10, + }).Info("A group of walrus emerges from the ocean") +} +``` + +#### Fields + +Logrus encourages careful, structured logging through logging fields instead of +long, unparseable error messages. For example, instead of: `log.Fatalf("Failed +to send event %s to topic %s with key %d")`, you should log the much more +discoverable: + +```go +log.WithFields(log.Fields{ + "event": event, + "topic": topic, + "key": key, +}).Fatal("Failed to send event") +``` + +We've found this API forces you to think about logging in a way that produces +much more useful logging messages. We've been in countless situations where just +a single added field to a log statement that was already there would've saved us +hours. The `WithFields` call is optional. + +In general, with Logrus using any of the `printf`-family functions should be +seen as a hint you should add a field, however, you can still use the +`printf`-family functions with Logrus. + +#### Default Fields + +Often it's helpful to have fields _always_ attached to log statements in an +application or parts of one. For example, you may want to always log the +`request_id` and `user_ip` in the context of a request. Instead of writing +`log.WithFields(log.Fields{"request_id": request_id, "user_ip": user_ip})` on +every line, you can create a `logrus.Entry` to pass around instead: + +```go +requestLogger := log.WithFields(log.Fields{"request_id": request_id, "user_ip": user_ip}) +requestLogger.Info("something happened on that request") # will log request_id and user_ip +requestLogger.Warn("something not great happened") +``` + +#### Hooks + +You can add hooks for logging levels. For example to send errors to an exception +tracking service on `Error`, `Fatal` and `Panic`, info to StatsD or log to +multiple places simultaneously, e.g. syslog. + +Logrus comes with [built-in hooks](hooks/). Add those, or your custom hook, in +`init`: + +```go +import ( + log "github.com/sirupsen/logrus" + "gopkg.in/gemnasium/logrus-airbrake-hook.v2" // the package is named "airbrake" + logrus_syslog "github.com/sirupsen/logrus/hooks/syslog" + "log/syslog" +) + +func init() { + + // Use the Airbrake hook to report errors that have Error severity or above to + // an exception tracker. You can create custom hooks, see the Hooks section. + log.AddHook(airbrake.NewHook(123, "xyz", "production")) + + hook, err := logrus_syslog.NewSyslogHook("udp", "localhost:514", syslog.LOG_INFO, "") + if err != nil { + log.Error("Unable to connect to local syslog daemon") + } else { + log.AddHook(hook) + } +} +``` +Note: Syslog hook also support connecting to local syslog (Ex. "/dev/log" or "/var/run/syslog" or "/var/run/log"). For the detail, please check the [syslog hook README](hooks/syslog/README.md). + +A list of currently known of service hook can be found in this wiki [page](https://github.com/sirupsen/logrus/wiki/Hooks) + + +#### Level logging + +Logrus has seven logging levels: Trace, Debug, Info, Warning, Error, Fatal and Panic. + +```go +log.Trace("Something very low level.") +log.Debug("Useful debugging information.") +log.Info("Something noteworthy happened!") +log.Warn("You should probably take a look at this.") +log.Error("Something failed but I'm not quitting.") +// Calls os.Exit(1) after logging +log.Fatal("Bye.") +// Calls panic() after logging +log.Panic("I'm bailing.") +``` + +You can set the logging level on a `Logger`, then it will only log entries with +that severity or anything above it: + +```go +// Will log anything that is info or above (warn, error, fatal, panic). Default. +log.SetLevel(log.InfoLevel) +``` + +It may be useful to set `log.Level = logrus.DebugLevel` in a debug or verbose +environment if your application has that. + +#### Entries + +Besides the fields added with `WithField` or `WithFields` some fields are +automatically added to all logging events: + +1. `time`. The timestamp when the entry was created. +2. `msg`. The logging message passed to `{Info,Warn,Error,Fatal,Panic}` after + the `AddFields` call. E.g. `Failed to send event.` +3. `level`. The logging level. E.g. `info`. + +#### Environments + +Logrus has no notion of environment. + +If you wish for hooks and formatters to only be used in specific environments, +you should handle that yourself. For example, if your application has a global +variable `Environment`, which is a string representation of the environment you +could do: + +```go +import ( + log "github.com/sirupsen/logrus" +) + +init() { + // do something here to set environment depending on an environment variable + // or command-line flag + if Environment == "production" { + log.SetFormatter(&log.JSONFormatter{}) + } else { + // The TextFormatter is default, you don't actually have to do this. + log.SetFormatter(&log.TextFormatter{}) + } +} +``` + +This configuration is how `logrus` was intended to be used, but JSON in +production is mostly only useful if you do log aggregation with tools like +Splunk or Logstash. + +#### Formatters + +The built-in logging formatters are: + +* `logrus.TextFormatter`. Logs the event in colors if stdout is a tty, otherwise + without colors. + * *Note:* to force colored output when there is no TTY, set the `ForceColors` + field to `true`. To force no colored output even if there is a TTY set the + `DisableColors` field to `true`. For Windows, see + [github.com/mattn/go-colorable](https://github.com/mattn/go-colorable). + * When colors are enabled, levels are truncated to 4 characters by default. To disable + truncation set the `DisableLevelTruncation` field to `true`. + * All options are listed in the [generated docs](https://godoc.org/github.com/sirupsen/logrus#TextFormatter). +* `logrus.JSONFormatter`. Logs fields as JSON. + * All options are listed in the [generated docs](https://godoc.org/github.com/sirupsen/logrus#JSONFormatter). + +Third party logging formatters: + +* [`FluentdFormatter`](https://github.com/joonix/log). Formats entries that can be parsed by Kubernetes and Google Container Engine. +* [`GELF`](https://github.com/fabienm/go-logrus-formatters). Formats entries so they comply to Graylog's [GELF 1.1 specification](http://docs.graylog.org/en/2.4/pages/gelf.html). +* [`logstash`](https://github.com/bshuster-repo/logrus-logstash-hook). Logs fields as [Logstash](http://logstash.net) Events. +* [`prefixed`](https://github.com/x-cray/logrus-prefixed-formatter). Displays log entry source along with alternative layout. +* [`zalgo`](https://github.com/aybabtme/logzalgo). Invoking the P͉̫o̳̼̊w̖͈̰͎e̬͔̭͂r͚̼̹̲ ̫͓͉̳͈ō̠͕͖̚f̝͍̠ ͕̲̞͖͑Z̖̫̤̫ͪa͉̬͈̗l͖͎g̳̥o̰̥̅!̣͔̲̻͊̄ ̙̘̦̹̦. +* [`nested-logrus-formatter`](https://github.com/antonfisher/nested-logrus-formatter). Converts logrus fields to a nested structure. + +You can define your formatter by implementing the `Formatter` interface, +requiring a `Format` method. `Format` takes an `*Entry`. `entry.Data` is a +`Fields` type (`map[string]interface{}`) with all your fields as well as the +default ones (see Entries section above): + +```go +type MyJSONFormatter struct { +} + +log.SetFormatter(new(MyJSONFormatter)) + +func (f *MyJSONFormatter) Format(entry *Entry) ([]byte, error) { + // Note this doesn't include Time, Level and Message which are available on + // the Entry. Consult `godoc` on information about those fields or read the + // source of the official loggers. + serialized, err := json.Marshal(entry.Data) + if err != nil { + return nil, fmt.Errorf("Failed to marshal fields to JSON, %v", err) + } + return append(serialized, '\n'), nil +} +``` + +#### Logger as an `io.Writer` + +Logrus can be transformed into an `io.Writer`. That writer is the end of an `io.Pipe` and it is your responsibility to close it. + +```go +w := logger.Writer() +defer w.Close() + +srv := http.Server{ + // create a stdlib log.Logger that writes to + // logrus.Logger. + ErrorLog: log.New(w, "", 0), +} +``` + +Each line written to that writer will be printed the usual way, using formatters +and hooks. The level for those entries is `info`. + +This means that we can override the standard library logger easily: + +```go +logger := logrus.New() +logger.Formatter = &logrus.JSONFormatter{} + +// Use logrus for standard log output +// Note that `log` here references stdlib's log +// Not logrus imported under the name `log`. +log.SetOutput(logger.Writer()) +``` + +#### Rotation + +Log rotation is not provided with Logrus. Log rotation should be done by an +external program (like `logrotate(8)`) that can compress and delete old log +entries. It should not be a feature of the application-level logger. + +#### Tools + +| Tool | Description | +| ---- | ----------- | +|[Logrus Mate](https://github.com/gogap/logrus_mate)|Logrus mate is a tool for Logrus to manage loggers, you can initial logger's level, hook and formatter by config file, the logger will generated with different config at different environment.| +|[Logrus Viper Helper](https://github.com/heirko/go-contrib/tree/master/logrusHelper)|An Helper around Logrus to wrap with spf13/Viper to load configuration with fangs!

This is implemented through the `test` hook and provides: + +* decorators for existing logger (`test.NewLocal` and `test.NewGlobal`) which basically just add the `test` hook +* a test logger (`test.NewNullLogger`) that just records log messages (and does not output any): + +```go +import( + "github.com/sirupsen/logrus" + "github.com/sirupsen/logrus/hooks/test" + "github.com/stretchr/testify/assert" + "testing" +) + +func TestSomething(t*testing.T){ + logger, hook := test.NewNullLogger() + logger.Error("Helloerror") + + assert.Equal(t, 1, len(hook.Entries)) + assert.Equal(t, logrus.ErrorLevel, hook.LastEntry().Level) + assert.Equal(t, "Helloerror", hook.LastEntry().Message) + + hook.Reset() + assert.Nil(t, hook.LastEntry()) +} +``` + +#### Fatal handlers + +Logrus can register one or more functions that will be called when any `fatal` +level message is logged. The registered handlers will be executed before +logrus performs a `os.Exit(1)`. This behavior may be helpful if callers need +to gracefully shutdown. Unlike a `panic("Something went wrong...")` call which can be intercepted with a deferred `recover` a call to `os.Exit(1)` can not be intercepted. + +``` +... +handler := func() { + // gracefully shutdown something... +} +logrus.RegisterExitHandler(handler) +... +``` + +#### Thread safety + +By default, Logger is protected by a mutex for concurrent writes. The mutex is held when calling hooks and writing logs. +If you are sure such locking is not needed, you can call logger.SetNoLock() to disable the locking. + +Situation when locking is not needed includes: + +* You have no hooks registered, or hooks calling is already thread-safe. + +* Writing to logger.Out is already thread-safe, for example: + + 1) logger.Out is protected by locks. + + 2) logger.Out is a os.File handler opened with `O_APPEND` flag, and every write is smaller than 4k. (This allow multi-thread/multi-process writing) + + (Refer to http://www.notthewizard.com/2014/06/17/are-files-appends-really-atomic/) diff --git a/vendor/github.com/sirupsen/logrus/appveyor.yml b/vendor/github.com/sirupsen/logrus/appveyor.yml new file mode 100644 index 000000000..96c2ce15f --- /dev/null +++ b/vendor/github.com/sirupsen/logrus/appveyor.yml @@ -0,0 +1,14 @@ +version: "{build}" +platform: x64 +clone_folder: c:\gopath\src\github.com\sirupsen\logrus +environment: + GOPATH: c:\gopath +branches: + only: + - master +install: + - set PATH=%GOPATH%\bin;c:\go\bin;%PATH% + - go version +build_script: + - go get -t + - go test diff --git a/vendor/github.com/sirupsen/logrus/go.mod b/vendor/github.com/sirupsen/logrus/go.mod new file mode 100644 index 000000000..12fdf9898 --- /dev/null +++ b/vendor/github.com/sirupsen/logrus/go.mod @@ -0,0 +1,10 @@ +module github.com/sirupsen/logrus + +require ( + github.com/davecgh/go-spew v1.1.1 // indirect + github.com/konsorten/go-windows-terminal-sequences v1.0.1 + github.com/pmezard/go-difflib v1.0.0 // indirect + github.com/stretchr/objx v0.1.1 // indirect + github.com/stretchr/testify v1.2.2 + golang.org/x/sys v0.0.0-20190422165155-953cdadca894 +) diff --git a/vendor/github.com/sirupsen/logrus/go.sum b/vendor/github.com/sirupsen/logrus/go.sum new file mode 100644 index 000000000..596c318b9 --- /dev/null +++ b/vendor/github.com/sirupsen/logrus/go.sum @@ -0,0 +1,16 @@ +github.com/davecgh/go-spew v1.1.1 h1:vj9j/u1bqnvCEfJOwUhtlOARqs3+rkHYY13jYWTU97c= +github.com/davecgh/go-spew v1.1.1/go.mod h1:J7Y8YcW2NihsgmVo/mv3lAwl/skON4iLHjSsI+c5H38= +github.com/konsorten/go-windows-terminal-sequences v0.0.0-20180402223658-b729f2633dfe h1:CHRGQ8V7OlCYtwaKPJi3iA7J+YdNKdo8j7nG5IgDhjs= +github.com/konsorten/go-windows-terminal-sequences v0.0.0-20180402223658-b729f2633dfe/go.mod h1:T0+1ngSBFLxvqU3pZ+m/2kptfBszLMUkC4ZK/EgS/cQ= +github.com/konsorten/go-windows-terminal-sequences v1.0.1 h1:mweAR1A6xJ3oS2pRaGiHgQ4OO8tzTaLawm8vnODuwDk= +github.com/konsorten/go-windows-terminal-sequences v1.0.1/go.mod h1:T0+1ngSBFLxvqU3pZ+m/2kptfBszLMUkC4ZK/EgS/cQ= +github.com/pmezard/go-difflib v1.0.0 h1:4DBwDE0NGyQoBHbLQYPwSUPoCMWR5BEzIk/f1lZbAQM= +github.com/pmezard/go-difflib v1.0.0/go.mod h1:iKH77koFhYxTK1pcRnkKkqfTogsbg7gZNVY4sRDYZ/4= +github.com/stretchr/objx v0.1.1 h1:2vfRuCMp5sSVIDSqO8oNnWJq7mPa6KVP3iPIwFBuy8A= +github.com/stretchr/objx v0.1.1/go.mod h1:HFkY916IF+rwdDfMAkV7OtwuqBVzrE8GR6GFx+wExME= +github.com/stretchr/testify v1.2.2 h1:bSDNvY7ZPG5RlJ8otE/7V6gMiyenm9RtJ7IUVIAoJ1w= +github.com/stretchr/testify v1.2.2/go.mod h1:a8OnRcib4nhh0OaRAV+Yts87kKdq0PP7pXfy6kDkUVs= +golang.org/x/sys v0.0.0-20180905080454-ebe1bf3edb33 h1:I6FyU15t786LL7oL/hn43zqTuEGr4PN7F4XJ1p4E3Y8= +golang.org/x/sys v0.0.0-20180905080454-ebe1bf3edb33/go.mod h1:STP8DvDyc/dI5b8T5hshtkjS+E42TnysNCUPdjciGhY= +golang.org/x/sys v0.0.0-20190422165155-953cdadca894 h1:Cz4ceDQGXuKRnVBDTS23GTn/pU5OE2C0WrNTOYK1Uuc= +golang.org/x/sys v0.0.0-20190422165155-953cdadca894/go.mod h1:h1NjWce9XRLGQEsW7wpKNCjG9DtNlClVuFLEZdDNbEs= diff --git a/vendor/github.com/soheilhy/cmux/.gitignore b/vendor/github.com/soheilhy/cmux/.gitignore new file mode 100644 index 000000000..daf913b1b --- /dev/null +++ b/vendor/github.com/soheilhy/cmux/.gitignore @@ -0,0 +1,24 @@ +# Compiled Object files, Static and Dynamic libs (Shared Objects) +*.o +*.a +*.so + +# Folders +_obj +_test + +# Architecture specific extensions/prefixes +*.[568vq] +[568vq].out + +*.cgo1.go +*.cgo2.c +_cgo_defun.c +_cgo_gotypes.go +_cgo_export.* + +_testmain.go + +*.exe +*.test +*.prof diff --git a/vendor/github.com/soheilhy/cmux/.travis.yml b/vendor/github.com/soheilhy/cmux/.travis.yml new file mode 100644 index 000000000..4bc48e066 --- /dev/null +++ b/vendor/github.com/soheilhy/cmux/.travis.yml @@ -0,0 +1,29 @@ +language: go + +go: + - 1.6 + - 1.7 + - 1.8 + - tip + +matrix: + allow_failures: + - go: tip + +gobuild_args: -race + +before_install: + - if [[ $TRAVIS_GO_VERSION == 1.6* ]]; then go get -u github.com/kisielk/errcheck; fi + - if [[ $TRAVIS_GO_VERSION == 1.6* ]]; then go get -u github.com/golang/lint/golint; fi + +before_script: + - '!

Simply create your commands. + +Ideally you place this in app/cmd/root.go: + +```go +var rootCmd = &cobra.Command{ + Use: "hugo", + Short: "Hugo is a very fast static site generator", + Long: `A Fast and Flexible Static Site Generator built with + love by spf13 and friends in Go. + Complete documentation is available at http://hugo.spf13.com`, + Run: func(cmd *cobra.Command, args []string) { + // Do Stuff Here + }, +} + +func Execute() { + if err := rootCmd.Execute(); err != nil { + fmt.Println(err) + os.Exit(1) + } +} +``` + +You will additionally define flags and handle configuration in your init() function. + +For example cmd/root.go: + +```go +import ( + "fmt" + "os" + + homedir "github.com/mitchellh/go-homedir" + "github.com/spf13/cobra" + "github.com/spf13/viper" +) + +func init() { + cobra.OnInitialize(initConfig) + rootCmd.PersistentFlags().StringVar(&cfgFile, "config", "", "config file (default is $HOME/.cobra.yaml)") + rootCmd.PersistentFlags().StringVarP(&projectBase, "projectbase", "b", "", "base project directory eg. github.com/spf13/") + rootCmd.PersistentFlags().StringP("author", "a", "YOUR NAME", "Author name for copyright attribution") + rootCmd.PersistentFlags().StringVarP(&userLicense, "license", "l", "", "Name of license for the project (can provide `licensetext` in config)") + rootCmd.PersistentFlags().Bool("viper", true, "Use Viper for configuration") + viper.BindPFlag("author", rootCmd.PersistentFlags().Lookup("author")) + viper.BindPFlag("projectbase", rootCmd.PersistentFlags().Lookup("projectbase")) + viper.BindPFlag("useViper", rootCmd.PersistentFlags().Lookup("viper")) + viper.SetDefault("author", "NAME HERE ") + viper.SetDefault("license", "apache") +} + +func initConfig() { + // Don't forget to read config either from cfgFile or from home directory! + if cfgFile != "" { + // Use config file from the flag. + viper.SetConfigFile(cfgFile) + } else { + // Find home directory. + home, err := homedir.Dir() + if err != nil { + fmt.Println(err) + os.Exit(1) + } + + // Search config in home directory with name ".cobra" (without extension). + viper.AddConfigPath(home) + viper.SetConfigName(".cobra") + } + + if err := viper.ReadInConfig(); err != nil { + fmt.Println("Can't read config:", err) + os.Exit(1) + } +} +``` + +### Create your main.go + +With the root command you need to have your main function execute it. +Execute should be run on the root for clarity, though it can be called on any command. + +In a Cobra app, typically the main.go file is very bare.

This is Hugo's`, + Run: func(cmd *cobra.Command, args []string) { + fmt.Println("Hugo Static Site Generator v0.9 -- HEAD") + }, +} +``` + +## Working with Flags + +Flags provide modifiers to control how the action command operates. + +### Assign flags to a command + +Since the flags are defined and used in different locations, we need to +define a variable outside with the correct scope to assign the flag to +work with. + +```go +var Verbose bool +var Source string +``` + +There are two different approaches to assign a flag. + +### Persistent Flags + +A flag can be 'persistent' meaning that this flag will be available to the +command it's assigned to as well as every command under that command. For +global flags, assign a flag as a persistent flag on the root. + +```go +rootCmd.PersistentFlags().BoolVarP(&Verbose, "verbose", "v", false, "verbose output") +``` + +### Local Flags + +A flag can also be assigned locally which will only apply to that specific command. + +```go +rootCmd.Flags().StringVarP(&Source, "source", "s", "", "Source directory to read from") +``` + +### Local Flag on Parent Commands + +By default Cobra only parses local flags on the target command, any local flags on +parent commands are ignored. By enabling `Command.TraverseChildren` Cobra will +parse local flags on each command before executing the target command. + +```go +command := cobra.Command{ + Use: "print [OPTIONS] [COMMANDS]", + TraverseChildren: true, +} +``` + +### Bind Flags with Config + +You can also bind your flags with [viper](https://github.com/spf13/viper): +```go +var author string + +func init() { + rootCmd.PersistentFlags().StringVar(&author, "author", "YOUR NAME", "Author name for copyright attribution") + viper.BindPFlag("author", rootCmd.PersistentFlags().Lookup("author")) +} +``` + +In this example the persistent flag `author` is bound with `viper`. +**Note**, that the variable `author` will not be set to the value from config, +when the `--author` flag is not provided by user. + +More in [viper documentation](https://github.com/spf13/viper#working-with-flags). + +### Required flags + +Flags are optional by default. If instead you wish your command to report an error +when a flag has not been set, mark it as required: +```go +rootCmd.Flags().StringVarP(&Region, "region", "r", "", "AWS region (required)") +rootCmd.MarkFlagRequired("region") +``` + +## Positional and Custom Arguments + +Validation of positional arguments can be specified using the `Args` field +of `Command`. + +The following validators are built in: + +- `NoArgs` - the command will report an error if there are any positional args. +- `ArbitraryArgs` - the command will accept any args. +- `OnlyValidArgs` - the command will report an error if there are any positional args that are not in the `ValidArgs` field of `Command`. +- `MinimumNArgs(int)` - the command will report an error if there are not at least N positional args. +- `MaximumNArgs(int)` - the command will report an error if there are more than N positional args. +- `ExactArgs(int)` - the command will report an error if there are not exactly N positional args. +- `RangeArgs(min, max)` - the command will report an error if the number of args is not between the minimum and maximum number of expected args. + +An example of setting the custom validator: + +```go +var cmd = &cobra.Command{ + Short: "hello", + Args: func(cmd *cobra.Command, args []string) error { + if len(args) < 1 { + return errors.New("requires at least one arg") + } + if myapp.IsValidColor(args[0]) { + return nil + } + return fmt.Errorf("invalid color specified: %s", args[0]) + }, + Run: func(cmd *cobra.Command, args []string) { + fmt.Println("Hello, World!") + }, +} +``` + +## Example + +In the example below, we have defined three commands. Two are at the top level +and one (cmdTimes) is a child of one of the top commands. In this case the root +is not executable meaning that a subcommand is required. This is accomplished +by not providing a 'Run' for the 'rootCmd'. + +We have only defined one flag for a single command. + +More documentation about flags is available at https://github.com/spf13/pflag + +```go +package main + +import ( + "fmt" + "strings" + + "github.com/spf13/cobra" +) + +func main() { + var echoTimes int + + var cmdPrint = &cobra.Command{ + Use: "print [string to print]", + Short: "Print anything to the screen", + Long: `print is for printing anything back to the screen. +For many years people have printed back to the screen.`, + Args: cobra.MinimumNArgs(1), + Run: func(cmd *cobra.Command, args []string) { + fmt.Println("Print: " + strings.Join(args, " ")) + }, + } + + var cmdEcho = &cobra.Command{ + Use: "echo [string to echo]", + Short: "Echo anything to the screen", + Long: `echo is for echoing anything back. +Echo works a lot like print, except it has a child command.`, + Args: cobra.MinimumNArgs(1), + Run: func(cmd *cobra.Command, args []string) { + fmt.Println("Print: " + strings.Join(args, " ")) + }, + } + + var cmdTimes = &cobra.Command{ + Use: "times [# times] [string to echo]", + Short: "Echo anything to the screen more times", + Long: `echo things multiple times back to the user by providing +a count and a string.`, + Args: cobra.MinimumNArgs(1), + Run: func(cmd *cobra.Command, args []string) { + for i := 0; i < echoTimes; i++ { + fmt.Println("Echo: " + strings.Join(args, " ")) + } + }, + } + + cmdTimes.Flags().IntVarP(&echoTimes, "times", "t", 1, "times to echo the input") + + var rootCmd = &cobra.Command{Use: "app"} + rootCmd.AddCommand(cmdPrint, cmdEcho) + cmdEcho.AddCommand(cmdTimes) + rootCmd.Execute() +} +``` + +For a more complete example of a larger application, please checkout [Hugo](http://gohugo.io/). + +## Help Command + +Cobra automatically adds a help command to your application when you have subcommands. +This will be called when a user runs 'app help'. Additionally, help will also +support all other commands as input. Say, for instance, you have a command called +'create' without any additional configuration; Cobra will work when 'app help +create' is called. Every command will automatically have the '--help' flag added. + +### Example + +The following output is automatically generated by Cobra. Nothing beyond the +command and flag definitions are needed. + + $ cobra help + + Cobra is a CLI library for Go that empowers applications. + This application is a tool to generate the needed files + to quickly create a Cobra application. + + Usage: + cobra [command] + + Available Commands: + add Add a command to a Cobra Application + help Help about any command + init Initialize a Cobra Application + + Flags: + -a, --author string author name for copyright attribution (default "YOUR NAME") + --config string config file (default is $HOME/.cobra.yaml) + -h, --help help for cobra + -l, --license string name of license for the project + --viper use Viper for configuration (default true) + + Use "cobra [command] --help" for more information about a command. + + +Help is just a command like any other.

The template can be customized using the +`cmd.SetVersionTemplate(s string)` function. + +## PreRun and PostRun Hooks + +It is possible to run functions before or after the main `Run` function of your command. The `PersistentPreRun` and `PreRun` functions will be executed before `Run`. `PersistentPostRun` and `PostRun` will be executed after `Run`. The `Persistent*Run` functions will be inherited by children if they do not declare their own. These functions are run in the following order: + +- `PersistentPreRun` +- `PreRun` +- `Run` +- `PostRun` +- `PersistentPostRun` + +An example of two commands which use all of these features is below. When the subcommand is executed, it will run the root command's `PersistentPreRun` but not the root command's `PersistentPostRun`: + +```go +package main + +import ( + "fmt" + + "github.com/spf13/cobra" +) + +func main() { + + var rootCmd = &cobra.Command{ + Use: "root [sub]", + Short: "My root command", + PersistentPreRun: func(cmd *cobra.Command, args []string) { + fmt.Printf("Inside rootCmd PersistentPreRun with args: %v\n", args) + }, + PreRun: func(cmd *cobra.Command, args []string) { + fmt.Printf("Inside rootCmd PreRun with args: %v\n", args) + }, + Run: func(cmd *cobra.Command, args []string) { + fmt.Printf("Inside rootCmd Run with args: %v\n", args) + }, + PostRun: func(cmd *cobra.Command, args []string) { + fmt.Printf("Inside rootCmd PostRun with args: %v\n", args) + }, + PersistentPostRun: func(cmd *cobra.Command, args []string) { + fmt.Printf("Inside rootCmd PersistentPostRun with args: %v\n", args) + }, + } + + var subCmd = &cobra.Command{ + Use: "sub [no options!]", + Short: "My subcommand", + PreRun: func(cmd *cobra.Command, args []string) { + fmt.Printf("Inside subCmd PreRun with args: %v\n", args) + }, + Run: func(cmd *cobra.Command, args []string) { + fmt.Printf("Inside subCmd Run with args: %v\n", args) + }, + PostRun: func(cmd *cobra.Command, args []string) { + fmt.Printf("Inside subCmd PostRun with args: %v\n", args) + }, + PersistentPostRun: func(cmd *cobra.Command, args []string) { + fmt.Printf("Inside subCmd PersistentPostRun with args: %v\n", args) + }, + } + + rootCmd.AddCommand(subCmd) + + rootCmd.SetArgs([]string{""}) + rootCmd.Execute() + fmt.Println() + rootCmd.SetArgs([]string{"sub", "arg1", "arg2"}) + rootCmd.Execute() +} +``` + +Output: +``` +Inside rootCmd PersistentPreRun with args: [] +Inside rootCmd PreRun with args: [] +Inside rootCmd Run with args: [] +Inside rootCmd PostRun with args: [] +Inside rootCmd PersistentPostRun with args: [] + +Inside rootCmd PersistentPreRun with args: [arg1 arg2] +Inside subCmd PreRun with args: [arg1 arg2] +Inside subCmd Run with args: [arg1 arg2] +Inside subCmd PostRun with args: [arg1 arg2] +Inside subCmd PersistentPostRun with args: [arg1 arg2] +``` + +## Suggestions when "unknown command" happens + +Cobra will print automatic suggestions when "unknown command" errors happen. This allows Cobra to behave similarly to the `git` command when a typo happens. For example: + +``` +$ hugo srever +Error: unknown command "srever" for "hugo" + +Did you mean this? + server + +Run 'hugo --help' for usage. +``` + +Suggestions are automatic based on every subcommand registered and use an implementation of [Levenshtein distance](http://en.wikipedia.org/wiki/Levenshtein_distance). Every registered command that matches a minimum distance of 2 (ignoring case) will be displayed as a suggestion. + +If you need to disable suggestions or tweak the string distance in your command, use: + +```go +command.DisableSuggestions = true +``` + +or + +```go +command.SuggestionsMinimumDistance = 1 +``` + +You can also explicitly set names for which a given command will be suggested using the `SuggestFor` attribute. This allows suggestions for strings that are not close in terms of string distance, but makes sense in your set of commands and for some which you don't want aliases. Example: + +``` +$ kubectl remove +Error: unknown command "remove" for "kubectl" + +Did you mean this? + delete + +Run 'kubectl help' for usage. +``` + +## Generating documentation for your command + +Cobra can generate documentation based on subcommands, flags, etc. in the following formats: + +- [Markdown](doc/md_docs.md) +- [ReStructured Text](doc/rest_docs.md) +- [Man Page](doc/man_docs.md) + +## Generating bash completions + +Cobra can generate a bash-completion file.

Doing the above will cause `__custom_func()` to be called when the built in processor was unable to find a solution. In the case of kubernetes a valid command might look something like `kubectl get pod [mypod]`. If you type `kubectl get pod [tab][tab]` the `__customc_func()` will run because the cobra.Command only understood "kubectl" and "get." `__custom_func()` will see that the cobra.Command is "kubectl_get" and will thus call another helper `__kubectl_get_resource()`. `__kubectl_get_resource` will look at the 'nouns' collected. In our example the only noun will be `pod`. So it will call `__kubectl_parse_get pod`. `__kubectl_parse_get` will actually call out to kubernetes and get any pods. It will then set `COMPREPLY` to valid pods! + +## Have the completions code complete your 'nouns' + +In the above example "pod" was assumed to already be typed. But if you want `kubectl get [tab][tab]` to show a list of valid "nouns" you have to set them.

Doing so will give results like + +```bash +# kubectl get [tab][tab] +node pod replicationcontroller service +``` + +## Plural form and shortcuts for nouns + +If your nouns have a number of aliases, you can define them alongside `ValidArgs` using `ArgAliases`: + +```go +argAliases []string = { "pods", "nodes", "services", "svc", "replicationcontrollers", "rc" } + +cmd := &cobra.Command{ + ... + ValidArgs: validArgs, + ArgAliases: argAliases +} +``` + +The aliases are not shown to the user on tab completion, but they are accepted as valid nouns by +the completion algorithm if entered manually, e.g. in: + +```bash +# kubectl get rc [tab][tab] +backend frontend database +``` + +Note that without declaring `rc` as an alias, the completion algorithm would show the list of nouns +in this example again instead of the replication controllers. + +## Mark flags as required + +Most of the time completions will only show subcommands. But if a flag is required to make a subcommand work, you probably want it to show up when the user types [tab][tab]. Marking a flag as 'Required' is incredibly easy. + +```go +cmd.MarkFlagRequired("pod") +cmd.MarkFlagRequired("container") +``` + +and you'll get something like + +```bash +# kubectl exec [tab][tab][tab] +-c --container= -p --pod= +``` + +# Specify valid filename extensions for flags that take a filename + +In this example we use --filename= and expect to get a json or yaml file as the argument.

If you're using the flags themselves, +they are all pointers; if you bind to variables, they're values. + +``` go +fmt.Println("ip has value ", *ip) +fmt.Println("flagvar has value ", flagvar) +``` + +There are helpers function to get values later if you have the FlagSet but +it was difficult to keep up with all of the flag pointers in your code. +If you have a pflag.FlagSet with a flag called 'flagname' of type int you +can use GetInt() to get the int value. But notice that 'flagname' must exist +and it must be an int. GetString("flagname") will fail. + +``` go +i, err := flagset.GetInt("flagname") +``` + +After parsing, the arguments after the flag are available as the +slice flag.Args() or individually as flag.Arg(i). +The arguments are indexed from 0 through flag.NArg()-1. + +The pflag package also defines some new functions that are not in flag, +that give one-letter shorthands for flags. You can use these by appending +'P' to the name of any function that defines a flag. + +``` go +var ip = flag.IntP("flagname", "f", 1234, "help message") +var flagvar bool +func init() { + flag.BoolVarP(&flagvar, "boolname", "b", true, "help message") +} +flag.VarP(&flagVal, "varname", "v", "help message") +``` + +Shorthand letters can be used with single dashes on the command line. +Boolean shorthand flags can be combined with other shorthand flags. + +The default set of command-line flags is controlled by +top-level functions. The FlagSet type allows one to define +independent sets of flags, such as to implement subcommands +in a command-line interface. The methods of FlagSet are +analogous to the top-level functions for the command-line +flag set. + +## Setting no option default values for flags + +After you create a flag it is possible to set the pflag.NoOptDefVal for +the given flag. Doing this changes the meaning of the flag slightly. If +a flag has a NoOptDefVal and the flag is set on the command line without +an option the flag will be set to the NoOptDefVal. For example given: + +``` go +var ip = flag.IntP("flagname", "f", 1234, "help message") +flag.Lookup("flagname").NoOptDefVal = "4321" +``` + +Would result in something like + +| Parsed Arguments | Resulting Value | +| ------------- | ------------- | +| --flagname=1357 | ip=1357 | +| --flagname | ip=4321 | +| [nothing] | ip=1234 | + +## Command line flag syntax + +``` +--flag // boolean flags, or flags with no option default values +--flag x // only on flags without a default value +--flag=x +``` + +Unlike the flag package, a single dash before an option means something +different than a double dash. Single dashes signify a series of shorthand +letters for flags. All but the last shorthand letter must be boolean flags +or a flag with a default value + +``` +// boolean or flags where the 'no option default value' is set +-f +-f=true +-abc +but +-b true is INVALID + +// non-boolean and flags without a 'no option default value' +-n 1234 +-n=1234 +-n1234 + +// mixed +-abcs "hello" +-absd="hello" +-abcs1234 +``` + +Flag parsing stops after the terminator "--". Unlike the flag package, +flags can be interspersed with arguments anywhere on the command line +before this terminator. + +Integer flags accept 1234, 0664, 0x1234 and may be negative. +Boolean flags (in their long form) accept 1, 0, t, f, true, false, +TRUE, FALSE, True, False. +Duration flags accept any input valid for time.ParseDuration. + +## Mutating or "Normalizing" Flag names + +It is possible to set a custom flag name 'normalization function.'

Deprecating a flag/shorthand hides it from help text and prints a usage message when the deprecated flag/shorthand is used. + +**Example #1**: You want to deprecate a flag named "badflag" as well as inform the users what flag they should use instead. +```go +// deprecate a flag by specifying its name and a usage message +flags.MarkDeprecated("badflag", "please use --good-flag instead") +``` +This hides "badflag" from help text, and prints `Flag --badflag has been deprecated, please use --good-flag instead` when "badflag" is used. + +**Example #2**: You want to keep a flag name "noshorthandflag" but deprecate its shortname "n". +```go +// deprecate a flag shorthand by specifying its flag name and a usage message +flags.MarkShorthandDeprecated("noshorthandflag", "please use --noshorthandflag only") +``` +This hides the shortname "n" from help text, and prints `Flag shorthand -n has been deprecated, please use --noshorthandflag only` when the shorthand "n" is used. + +Note that usage message is essential here, and it should not be empty. + +## Hidden flags +It is possible to mark a flag as hidden, meaning it will still function as normal, however will not show up in usage/help text. + +**Example**: You have a flag named "secretFlag" that you need for internal use only and don't want it showing up in help text, or for its usage text to be available. +```go +// hide a flag by specifying its name +flags.MarkHidden("secretFlag") +``` + +## Disable sorting of flags +`pflag` allows you to disable sorting of flags for help and usage message. + +**Example**: +```go +flags.BoolP("verbose", "v", false, "verbose output") +flags.String("coolflag", "yeaah", "it's really cool flag") +flags.Int("usefulflag", 777, "sometimes it's very useful") +flags.SortFlags = false +flags.PrintDefaults() +``` +**Output**: +``` + -v, --verbose verbose output + --coolflag string it's really cool flag (default "yeaah") + --usefulflag int sometimes it's very useful (default 777) +``` + + +## Supporting Go flags when using pflag +In order to support flags defined using Go's `flag` package, they must be added to the `pflag` flagset. This is usually necessary +to support flags defined by third-party dependencies (e.g. `golang/glog`). + +**Example**: You want to add the Go flags to the `CommandLine` flagset +```go +import ( + goflag "flag" + flag "github.com/spf13/pflag" +) + +var ip *int = flag.Int("flagname", 1234, "help message for flagname") + +func main() { + flag.CommandLine.AddGoFlagSet(goflag.CommandLine) + flag.Parse() +} +``` + +## More info + +You can see the full reference documentation of the pflag package +[at godoc.org][3], or through go's standard documentation system by +running `godoc -http=:6060` and browsing to +[http://localhost:6060/pkg/github.com/spf13/pflag][2] after +installation. + +[2]: http://localhost:6060/pkg/github.com/spf13/pflag +[3]: http://godoc.org/github.com/spf13/pflag diff --git a/vendor/github.com/urfave/cli/.flake8 b/vendor/github.com/urfave/cli/.flake8 new file mode 100644 index 000000000..6deafc261 --- /dev/null +++ b/vendor/github.com/urfave/cli/.flake8 @@ -0,0 +1,2 @@ +[flake8] +max-line-length = 120 diff --git a/vendor/github.com/urfave/cli/.gitignore b/vendor/github.com/urfave/cli/.gitignore new file mode 100644 index 000000000..faf70c4c2 --- /dev/null +++ b/vendor/github.com/urfave/cli/.gitignore @@ -0,0 +1,2 @@ +*.coverprofile +node_modules/ diff --git a/vendor/github.com/urfave/cli/.travis.yml b/vendor/github.com/urfave/cli/.travis.yml new file mode 100644 index 000000000..cf8d0980d --- /dev/null +++ b/vendor/github.com/urfave/cli/.travis.yml @@ -0,0 +1,27 @@ +language: go +sudo: false +dist: trusty +osx_image: xcode8.3 +go: 1.8.x + +os: +- linux +- osx + +cache: + directories: + - node_modules + +before_script: +- go get github.com/urfave/gfmrun/... || true +- go get golang.org/x/tools/cmd/goimports +- if [ ! -f node_modules/.bin/markdown-toc ] ; then + npm install markdown-toc ; + fi + +script: +- ./runtests gen +- ./runtests vet +- ./runtests test +- ./runtests gfmrun +- ./runtests toc diff --git a/vendor/github.com/urfave/cli/CHANGELOG.md b/vendor/github.com/urfave/cli/CHANGELOG.md new file mode 100644 index 000000000..401eae5a2 --- /dev/null +++ b/vendor/github.com/urfave/cli/CHANGELOG.md @@ -0,0 +1,435 @@ +# Change Log + +**ATTN**: This project uses [semantic versioning](http://semver.org/). + +## [Unreleased] + +## 1.20.0 - 2017-08-10 + +### Fixed + +* `HandleExitCoder` is now correctly iterates over all errors in + a `MultiError`.

The current +`master` branch (mirrored as `v1`) is being manually merged into `v2` on +an irregular human-based schedule, but generally if one wants to "upgrade" to +`v2` *now* and accept the volatility (read: "awesomeness") that comes along with +that, please use whatever version pinning of your preference, such as via +`gopkg.in`: + +``` +$ go get gopkg.in/urfave/cli.v2 +``` + +``` go +... +import ( + "gopkg.in/urfave/cli.v2" // imports as package "cli" +) +... +``` + +### Pinning to the `v1` releases + +Similarly to the section above describing use of the `v2` branch, if one wants +to avoid any unexpected compatibility pains once `v2` becomes `master`, then +pinning to `v1` is an acceptable option, e.g.: + +``` +$ go get gopkg.in/urfave/cli.v1 +``` + +``` go +... +import ( + "gopkg.in/urfave/cli.v1" // imports as package "cli" +) +... +``` + +This will pull the latest tagged `v1` release (e.g. `v1.18.1` at the time of writing). + +## Getting Started + +One of the philosophies behind cli is that an API should be playful and full of +discovery. So a cli app can be as little as one line of code in `main()`. + + +``` go +package main + +import ( + "os" + + "github.com/urfave/cli" +) + +func main() { + cli.NewApp().Run(os.Args) +} +``` + +This app will run and show help text, but is not very useful. Let's give an +action to execute and some help documentation: + + +``` go +package main + +import ( + "fmt" + "os" + + "github.com/urfave/cli" +) + +func main() { + app := cli.NewApp() + app.Name = "boom" + app.Usage = "make an explosive entrance" + app.Action = func(c *cli.Context) error { + fmt.Println("boom! I say!") + return nil + } + + app.Run(os.Args) +} +``` + +Running this already gives you a ton of functionality, plus support for things +like subcommands and flags, which are covered below. + +## Examples + +Being a programmer can be a lonely job. Thankfully by the power of automation +that is not the case! Let's create a greeter app to fend off our demons of +loneliness! + +Start by creating a directory named `greet`, and within it, add a file, +`greet.go` with the following code in it: + + +``` go +package main + +import ( + "fmt" + "os" + + "github.com/urfave/cli" +) + +func main() { + app := cli.NewApp() + app.Name = "greet" + app.Usage = "fight the loneliness!" + app.Action = func(c *cli.Context) error { + fmt.Println("Hello friend!") + return nil + } + + app.Run(os.Args) +} +``` + +Install our command to the `$GOPATH/bin` directory: + +``` +$ go install +``` + +Finally run our new command: + +``` +$ greet +Hello friend! +``` + +cli also generates neat help text: + +``` +$ greet help +NAME: + greet - fight the loneliness! + +USAGE: + greet [global options] command [command options] [arguments...] + +VERSION: + 0.0.0 + +COMMANDS: + help, h Shows a list of commands or help for one command + +GLOBAL OPTIONS + --version Shows version information +``` + +### Arguments + +You can lookup arguments by calling the `Args` function on `cli.Context`, e.g.: + + +``` go +package main + +import ( + "fmt" + "os" + + "github.com/urfave/cli" +) + +func main() { + app := cli.NewApp() + + app.Action = func(c *cli.Context) error { + fmt.Printf("Hello %q", c.Args().Get(0)) + return nil + } + + app.Run(os.Args) +} +``` + +### Flags + +Setting and querying flags is simple. + + +``` go +package main + +import ( + "fmt" + "os" + + "github.com/urfave/cli" +) + +func main() { + app := cli.NewApp() + + app.Flags = []cli.Flag { + cli.StringFlag{ + Name: "lang", + Value: "english", + Usage: "language for the greeting", + }, + } + + app.Action = func(c *cli.Context) error { + name := "Nefertiti" + if c.NArg() > 0 { + name = c.Args().Get(0) + } + if c.String("lang") == "spanish" { + fmt.Println("Hola", name) + } else { + fmt.Println("Hello", name) + } + return nil + } + + app.Run(os.Args) +} +``` + +You can also set a destination variable for a flag, to which the content will be +scanned. + + +``` go +package main + +import ( + "os" + "fmt" + + "github.com/urfave/cli" +) + +func main() { + var language string + + app := cli.NewApp() + + app.Flags = []cli.Flag { + cli.StringFlag{ + Name: "lang", + Value: "english", + Usage: "language for the greeting", + Destination: &language, + }, + } + + app.Action = func(c *cli.Context) error { + name := "someone" + if c.NArg() > 0 { + name = c.Args()[0] + } + if language == "spanish" { + fmt.Println("Hola", name) + } else { + fmt.Println("Hello", name) + } + return nil + } + + app.Run(os.Args) +} +``` + +See full list of flags at http://godoc.org/github.com/urfave/cli + +#### Placeholder Values + +Sometimes it's useful to specify a flag's value within the usage string itself. +Such placeholders are indicated with back quotes. + +For example this: + + +```go +package main + +import ( + "os" + + "github.com/urfave/cli" +) + +func main() { + app := cli.NewApp() + + app.Flags = []cli.Flag{ + cli.StringFlag{ + Name: "config, c", + Usage: "Load configuration from `FILE`", + }, + } + + app.Run(os.Args) +} +``` + +Will result in help output like: + +``` +--config FILE, -c FILE Load configuration from FILE +``` + +Note that only the first placeholder is used. Subsequent back-quoted words will +be left as-is. + +#### Alternate Names + +You can set alternate (or short) names for flags by providing a comma-delimited +list for the `Name`. e.g. + + +``` go +package main + +import ( + "os" + + "github.com/urfave/cli" +) + +func main() { + app := cli.NewApp() + + app.Flags = []cli.Flag { + cli.StringFlag{ + Name: "lang, l", + Value: "english", + Usage: "language for the greeting", + }, + } + + app.Run(os.Args) +} +``` + +That flag can then be set with `--lang spanish` or `-l spanish`. Note that +giving two different forms of the same flag in the same command invocation is an +error. + +#### Ordering + +Flags for the application and commands are shown in the order they are defined. +However, it's possible to sort them from outside this library by using `FlagsByName` +or `CommandsByName` with `sort`. + +For example this: + + +``` go +package main + +import ( + "os" + "sort" + + "github.com/urfave/cli" +) + +func main() { + app := cli.NewApp() + + app.Flags = []cli.Flag { + cli.StringFlag{ + Name: "lang, l", + Value: "english", + Usage: "Language for the greeting", + }, + cli.StringFlag{ + Name: "config, c", + Usage: "Load configuration from `FILE`", + }, + } + + app.Commands = []cli.Command{ + { + Name: "complete", + Aliases: []string{"c"}, + Usage: "complete a task on the list", + Action: func(c *cli.Context) error { + return nil + }, + }, + { + Name: "add", + Aliases: []string{"a"}, + Usage: "add a task to the list", + Action: func(c *cli.Context) error { + return nil + }, + }, + } + + sort.Sort(cli.FlagsByName(app.Flags)) + sort.Sort(cli.CommandsByName(app.Commands)) + + app.Run(os.Args) +} +``` + +Will result in help output like: + +``` +--config FILE, -c FILE Load configuration from FILE +--lang value, -l value Language for the greeting (default: "english") +``` + +#### Values from the Environment + +You can also have the default value set from the environment via `EnvVar`. e.g. + + +``` go +package main + +import ( + "os" + + "github.com/urfave/cli" +) + +func main() { + app := cli.NewApp() + + app.Flags = []cli.Flag { + cli.StringFlag{ + Name: "lang, l", + Value: "english", + Usage: "language for the greeting", + EnvVar: "APP_LANG", + }, + } + + app.Run(os.Args) +} +``` + +The `EnvVar` may also be given as a comma-delimited "cascade", where the first +environment variable that resolves is used as the default. + + +``` go +package main + +import ( + "os" + + "github.com/urfave/cli" +) + +func main() { + app := cli.NewApp() + + app.Flags = []cli.Flag { + cli.StringFlag{ + Name: "lang, l", + Value: "english", + Usage: "language for the greeting", + EnvVar: "LEGACY_COMPAT_LANG,APP_LANG,LANG", + }, + } + + app.Run(os.Args) +} +``` + +#### Values from alternate input sources (YAML, TOML, and others) + +There is a separate package altsrc that adds support for getting flag values +from other file input sources. + +Currently supported input source formats: +* YAML +* TOML + +In order to get values for a flag from an alternate input source the following +code would be added to wrap an existing cli.Flag like below: + +``` go + altsrc.NewIntFlag(cli.IntFlag{Name: "test"}) +``` + +Initialization must also occur for these flags. Below is an example initializing +getting data from a yaml file below. + +``` go + command.Before = altsrc.InitInputSourceWithContext(command.Flags, NewYamlSourceFromFlagFunc("load")) +``` + +The code above will use the "load" string as a flag name to get the file name of +a yaml file from the cli.Context.

As a note +the "load" flag used would also have to be defined on the command flags in order +for this code snipped to work. + +Currently only the aboved specified formats are supported but developers can +add support for other input sources by implementing the +altsrc.InputSourceContext for their given sources. + +Here is a more complete sample of a command using YAML support: + + +``` go +package notmain + +import ( + "fmt" + "os" + + "github.com/urfave/cli" + "github.com/urfave/cli/altsrc" +) + +func main() { + app := cli.NewApp() + + flags := []cli.Flag{ + altsrc.NewIntFlag(cli.IntFlag{Name: "test"}), + cli.StringFlag{Name: "load"}, + } + + app.Action = func(c *cli.Context) error { + fmt.Println("yaml ist rad") + return nil + } + + app.Before = altsrc.InitInputSourceWithContext(flags, altsrc.NewYamlSourceFromFlagFunc("load")) + app.Flags = flags + + app.Run(os.Args) +} +``` + +### Subcommands + +Subcommands can be defined for a more git-like command line app. + + +```go +package main + +import ( + "fmt" + "os" + + "github.com/urfave/cli" +) + +func main() { + app := cli.NewApp() + + app.Commands = []cli.Command{ + { + Name: "add", + Aliases: []string{"a"}, + Usage: "add a task to the list", + Action: func(c *cli.Context) error { + fmt.Println("added task: ", c.Args().First()) + return nil + }, + }, + { + Name: "complete", + Aliases: []string{"c"}, + Usage: "complete a task on the list", + Action: func(c *cli.Context) error { + fmt.Println("completed task: ", c.Args().First()) + return nil + }, + }, + { + Name: "template", + Aliases: []string{"t"}, + Usage: "options for task templates", + Subcommands: []cli.Command{ + { + Name: "add", + Usage: "add a new template", + Action: func(c *cli.Context) error { + fmt.Println("new task template: ", c.Args().First()) + return nil + }, + }, + { + Name: "remove", + Usage: "remove an existing template", + Action: func(c *cli.Context) error { + fmt.Println("removed task template: ", c.Args().First()) + return nil + }, + }, + }, + }, + } + + app.Run(os.Args) +} +``` + +### Subcommands categories + +For additional organization in apps that have many subcommands, you can +associate a category for each command to group them together in the help +output. + +E.g. + +```go +package main + +import ( + "os" + + "github.com/urfave/cli" +) + +func main() { + app := cli.NewApp() + + app.Commands = []cli.Command{ + { + Name: "noop", + }, + { + Name: "add", + Category: "template", + }, + { + Name: "remove", + Category: "template", + }, + } + + app.Run(os.Args) +} +``` + +Will include: + +``` +COMMANDS: + noop + + Template actions: + add + remove +``` + +### Exit code + +Calling `App.Run` will not automatically call `os.Exit`, which means that by +default the exit code will "fall through" to being `0`.

I will +give it a code review and make sure that it does not break backwards +compatibility. If I or any other collaborators agree that it is in line with +the vision of the project, we will work with you to get the code into +a mergeable state and merge it into the master branch. + +If you have contributed something significant to the project, we will most +likely add you as a collaborator. As a collaborator you are given the ability +to merge others pull requests. It is very important that new code does not +break existing code, so be careful about what code you do choose to merge. + +If you feel like you have contributed to the project but have not yet been +added as a collaborator, we probably forgot to add you, please open an issue. diff --git a/vendor/github.com/urfave/cli/appveyor.yml b/vendor/github.com/urfave/cli/appveyor.yml new file mode 100644 index 000000000..1e1489c36 --- /dev/null +++ b/vendor/github.com/urfave/cli/appveyor.yml @@ -0,0 +1,26 @@ +version: "{build}" + +os: Windows Server 2016 + +image: Visual Studio 2017 + +clone_folder: c:\gopath\src\github.com\urfave\cli + +environment: + GOPATH: C:\gopath + GOVERSION: 1.8.x + PYTHON: C:\Python36-x64 + PYTHON_VERSION: 3.6.x + PYTHON_ARCH: 64 + +install: +- set PATH=%GOPATH%\bin;C:\go\bin;%PATH% +- go version +- go env +- go get github.com/urfave/gfmrun/... +- go get -v -t ./... + +build_script: +- python runtests vet +- python runtests test +- python runtests gfmrun diff --git a/vendor/github.com/urfave/cli/flag-types.json b/vendor/github.com/urfave/cli/flag-types.json new file mode 100644 index 000000000..122310785 --- /dev/null +++ b/vendor/github.com/urfave/cli/flag-types.json @@ -0,0 +1,93 @@ +[ + { + "name": "Bool", + "type": "bool", + "value": false, + "context_default": "false", + "parser": "strconv.ParseBool(f.Value.String())" + }, + { + "name": "BoolT", + "type": "bool", + "value": false, + "doctail": " that is true by default", + "context_default": "false", + "parser": "strconv.ParseBool(f.Value.String())" + }, + { + "name": "Duration", + "type": "time.Duration", + "doctail": " (see https://golang.org/pkg/time/#ParseDuration)", + "context_default": "0", + "parser": "time.ParseDuration(f.Value.String())" + }, + { + "name": "Float64", + "type": "float64", + "context_default": "0", + "parser": "strconv.ParseFloat(f.Value.String(), 64)" + }, + { + "name": "Generic", + "type": "Generic", + "dest": false, + "context_default": "nil", + "context_type": "interface{}" + }, + { + "name": "Int64", + "type": "int64", + "context_default": "0", + "parser": "strconv.ParseInt(f.Value.String(), 0, 64)" + }, + { + "name": "Int", + "type": "int", + "context_default": "0", + "parser": "strconv.ParseInt(f.Value.String(), 0, 64)", + "parser_cast": "int(parsed)" + }, + { + "name": "IntSlice", + "type": "*IntSlice", + "dest": false, + "context_default": "nil", + "context_type": "[]int", + "parser": "(f.Value.(*IntSlice)).Value(), error(nil)" + }, + { + "name": "Int64Slice", + "type": "*Int64Slice", + "dest": false, + "context_default": "nil", + "context_type": "[]int64", + "parser": "(f.Value.(*Int64Slice)).Value(), error(nil)" + }, + { + "name": "String", + "type": "string", + "context_default": "\"\"", + "parser": "f.Value.String(), error(nil)" + }, + { + "name": "StringSlice", + "type": "*StringSlice", + "dest": false, + "context_default": "nil", + "context_type": "[]string", + "parser": "(f.Value.(*StringSlice)).Value(), error(nil)" + }, + { + "name": "Uint64", + "type": "uint64", + "context_default": "0", + "parser": "strconv.ParseUint(f.Value.String(), 0, 64)" + }, + { + "name": "Uint", + "type": "uint", + "context_default": "0", + "parser": "strconv.ParseUint(f.Value.String(), 0, 64)", + "parser_cast": "uint(parsed)" + } +] diff --git a/vendor/github.com/urfave/cli/generate-flag-types b/vendor/github.com/urfave/cli/generate-flag-types new file mode 100644 index 000000000..7147381ce --- /dev/null +++ b/vendor/github.com/urfave/cli/generate-flag-types @@ -0,0 +1,255 @@ +#!/usr/bin/env python +""" +The flag types that ship with the cli library have many things in common, and +so we can take advantage of the `go generate` command to create much of the +source code from a list of definitions.

[Bolt][bolt] key/value +store. The purpose of this fork is to provide the Go community with an active +maintenance and development target for Bolt; the goal is improved reliability +and stability. bbolt includes bug fixes, performance enhancements, and features +not found in Bolt while preserving backwards compatibility with the Bolt API. + +Bolt is a pure Go key/value store inspired by [Howard Chu's][hyc_symas] +[LMDB project][lmdb]. The goal of the project is to provide a simple, +fast, and reliable database for projects that don't require a full database +server such as Postgres or MySQL. + +Since Bolt is meant to be used as such a low-level piece of functionality, +simplicity is key. The API will be small and only focus on getting values +and setting values. That's it. + +[gh_ben]: https://github.com/benbjohnson +[bolt]: https://github.com/boltdb/bolt +[hyc_symas]: https://twitter.com/hyc_symas +[lmdb]: http://symas.com/mdb/ + +## Project Status + +Bolt is stable, the API is fixed, and the file format is fixed. Full unit +test coverage and randomized black box testing are used to ensure database +consistency and thread safety. Bolt is currently used in high-load production +environments serving databases as large as 1TB. Many companies such as +Shopify and Heroku use Bolt-backed services every day. + +## Project versioning + +bbolt uses [semantic versioning](http://semver.org). +API should not change between patch and minor releases. +New minor versions may add additional features to the API. + +## Table of Contents + + - [Getting Started](#getting-started) + - [Installing](#installing) + - [Opening a database](#opening-a-database) + - [Transactions](#transactions) + - [Read-write transactions](#read-write-transactions) + - [Read-only transactions](#read-only-transactions) + - [Batch read-write transactions](#batch-read-write-transactions) + - [Managing transactions manually](#managing-transactions-manually) + - [Using buckets](#using-buckets) + - [Using key/value pairs](#using-keyvalue-pairs) + - [Autoincrementing integer for the bucket](#autoincrementing-integer-for-the-bucket) + - [Iterating over keys](#iterating-over-keys) + - [Prefix scans](#prefix-scans) + - [Range scans](#range-scans) + - [ForEach()](#foreach) + - [Nested buckets](#nested-buckets) + - [Database backups](#database-backups) + - [Statistics](#statistics) + - [Read-Only Mode](#read-only-mode) + - [Mobile Use (iOS/Android)](#mobile-use-iosandroid) + - [Resources](#resources) + - [Comparison with other databases](#comparison-with-other-databases) + - [Postgres, MySQL, & other relational databases](#postgres-mysql--other-relational-databases) + - [LevelDB, RocksDB](#leveldb-rocksdb) + - [LMDB](#lmdb) + - [Caveats & Limitations](#caveats--limitations) + - [Reading the Source](#reading-the-source) + - [Other Projects Using Bolt](#other-projects-using-bolt) + +## Getting Started + +### Installing + +To start using Bolt, install Go and run `go get`: + +```sh +$ go get go.etcd.io/bbolt/... +``` + +This will retrieve the library and install the `bolt` command line utility into +your `$GOBIN` path. + + +### Importing bbolt + +To use bbolt as an embedded key-value store, import as: + +```go +import bolt "go.etcd.io/bbolt" + +db, err := bolt.Open(path, 0666, nil) +if err != nil { + return err +} +defer db.Close() +``` + + +### Opening a database + +The top-level object in Bolt is a `DB`. 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. + +Read-only transactions and read-write 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 a read-only transaction is open. + + +#### 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. Read-only mode +uses a shared lock to allow multiple processes to read from the database but +it will block any processes from opening the database in read-write mode. + +```go +db, err := bolt.Open("my.db", 0666, &bolt.Options{ReadOnly: true}) +if err != nil { + log.Fatal(err) +} +``` + +### Mobile Use (iOS/Android) + +Bolt is able to run on mobile devices by leveraging the binding feature of the +[gomobile](https://github.com/golang/mobile) tool. Create a struct that will +contain your database logic and a reference to a `*bolt.DB` with a initializing +constructor that takes in a filepath where the database file will be stored. +Neither Android nor iOS require extra permissions or cleanup from using this method. + +```go +func NewBoltDB(filepath string) *BoltDB { + db, err := bolt.Open(filepath+"/demo.db", 0600, nil) + if err != nil { + log.Fatal(err) + } + + return &BoltDB{db} +} + +type BoltDB struct { + db *bolt.DB + ... +} + +func (b *BoltDB) Path() string { + return b.db.Path() +} + +func (b *BoltDB) Close() { + b.db.Close() +} +``` + +Database logic should be defined as methods on this wrapper struct. + +To initialize this struct from the native language (both platforms now sync +their local storage to the cloud. These snippets disable that functionality for the +database file): + +#### Android + +```java +String path; +if (android.os.Build.VERSION.SDK_INT >=android.os.Build.VERSION_CODES.LOLLIPOP){ + path = getNoBackupFilesDir().getAbsolutePath(); +} else{ + path = getFilesDir().getAbsolutePath(); +} +Boltmobiledemo.BoltDB boltDB = Boltmobiledemo.NewBoltDB(path) +``` + +#### iOS + +```objc +- (void)demo { + NSString* path = [NSSearchPathForDirectoriesInDomains(NSLibraryDirectory, + NSUserDomainMask, + YES) objectAtIndex:0]; + GoBoltmobiledemoBoltDB * demo = GoBoltmobiledemoNewBoltDB(path); + [self addSkipBackupAttributeToItemAtPath:demo.path]; + //Some DB Logic would go here + [demo close]; +} + +- (BOOL)addSkipBackupAttributeToItemAtPath:(NSString *) filePathString +{ + NSURL* URL= [NSURL fileURLWithPath: filePathString]; + assert([[NSFileManager defaultManager] fileExistsAtPath: [URL path]]); + + NSError *error = nil; + BOOL success = [URL setResourceValue: [NSNumber numberWithBool: YES] + forKey: NSURLIsExcludedFromBackupKey error: &error]; + if(!success){ + NSLog(@"Error excluding %@ from backup %@", [URL lastPathComponent], error); + } + return success; +} + +``` + +## Resources + +For more information on getting started with Bolt, check out the following articles: + +* [Intro to BoltDB: Painless Performant Persistence](http://npf.io/2014/07/intro-to-boltdb-painless-performant-persistence/) by [Nate Finch](https://github.com/natefinch). +* [Bolt -- an embedded key/value database for Go](https://www.progville.com/go/bolt-embedded-db-golang/) by Progville + + +## Comparison with other databases + +### Postgres, MySQL, & other relational databases + +Relational databases structure data into rows and are only accessible through +the use of SQL. 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.

Put differently, using `encoding/json` and +`fmt.Fprintf` to log tons of `interface{}`s makes your application slow. + +Zap takes a different approach. It includes a reflection-free, zero-allocation +JSON encoder, and the base `Logger` strives to avoid serialization overhead +and allocations wherever possible. By building the high-level `SugaredLogger` +on that foundation, zap lets users *choose* when they need to count every +allocation and when they'd prefer a more familiar, loosely typed API. + +As measured by its own [benchmarking suite][], not only is zap more performant +than comparable structured logging packages — it's also faster than the +standard library.

Anyone using a +semver-aware dependency manager should now pin to `^1`. + +Breaking changes: + +* [#366][]: Add byte-oriented APIs to encoders to log UTF-8 encoded text without + casting from `[]byte` to `string`. +* [#364][]: To support buffering outputs, add `Sync` methods to `zapcore.Core`, + `zap.Logger`, and `zap.SugaredLogger`. +* [#371][]: Rename the `testutils` package to `zaptest`, which is less likely to + clash with other testing helpers. + +Bugfixes: + +* [#362][]: Make the ISO8601 time formatters fixed-width, which is friendlier + for tab-separated console output. +* [#369][]: Remove the automatic locks in `zapcore.NewCore`, which allows zap to + work with concurrency-safe `WriteSyncer` implementations. +* [#347][]: Stop reporting errors when trying to `fsync` standard out on Linux + systems. +* [#373][]: Report the correct caller from zap's standard library + interoperability wrappers. + +Enhancements: + +* [#348][]: Add a registry allowing third-party encodings to work with zap's + built-in `Config`. +* [#327][]: Make the representation of logger callers configurable (like times, + levels, and durations). +* [#376][]: Allow third-party encoders to use their own buffer pools, which + removes the last performance advantage that zap's encoders have over plugins. +* [#346][]: Add `CombineWriteSyncers`, a convenience function to tee multiple + `WriteSyncer`s and lock the result. +* [#365][]: Make zap's stacktraces compatible with mid-stack inlining (coming in + Go 1.9). +* [#372][]: Export zap's observing logger as `zaptest/observer`. This makes it + easier for particularly punctilious users to unit test their application's + logging. + +Thanks to @suyash, @htrendev, @flisky, @Ulexus, and @skipor for their +contributions to this release. + +## v1.0.0-rc.3 (7 Mar 2017) + +This is the third release candidate for zap's stable release. There are no +breaking changes. + +Bugfixes: + +* [#339][]: Byte slices passed to `zap.Any` are now correctly treated as binary blobs + rather than `[]uint8`. + +Enhancements: + +* [#307][]: Users can opt into colored output for log levels. +* [#353][]: In addition to hijacking the output of the standard library's + package-global logging functions, users can now construct a zap-backed + `log.Logger` instance. +* [#311][]: Frames from common runtime functions and some of zap's internal + machinery are now omitted from stacktraces. + +Thanks to @ansel1 and @suyash for their contributions to this release. + +## v1.0.0-rc.2 (21 Feb 2017) + +This is the second release candidate for zap's stable release. It includes two +breaking changes. + +Breaking changes: + +* [#316][]: Zap's global loggers are now fully concurrency-safe + (previously, users had to ensure that `ReplaceGlobals` was called before the + loggers were in use). However, they must now be accessed via the `L()` and + `S()` functions. Users can update their projects with + + ``` + gofmt -r "zap.L -> zap.L()" -w . + gofmt -r "zap.S -> zap.S()" -w . + ``` +* [#309][] and [#317][]: RC1 was mistakenly shipped with invalid + JSON and YAML struct tags on all config structs. This release fixes the tags + and adds static analysis to prevent similar bugs in the future. + +Bugfixes: + +* [#321][]: Redirecting the standard library's `log` output now + correctly reports the logger's caller. + +Enhancements: + +* [#325][] and [#333][]: Zap now transparently supports non-standard, rich + errors like those produced by `github.com/pkg/errors`. +* [#326][]: Though `New(nil)` continues to return a no-op logger, `NewNop()` is + now preferred. Users can update their projects with `gofmt -r 'zap.New(nil) -> + zap.NewNop()' -w .`. +* [#300][]: Incorrectly importing zap as `github.com/uber-go/zap` now returns a + more informative error. + +Thanks to @skipor and @chapsuk for their contributions to this release. + +## v1.0.0-rc.1 (14 Feb 2017) + +This is the first release candidate for zap's stable release. There are multiple +breaking changes and improvements from the pre-release version. Most notably: + +* **Zap's import path is now "go.uber.org/zap"** — all users will + need to update their code. +* User-facing types and functions remain in the `zap` package. Code relevant + largely to extension authors is now in the `zapcore` package. +* The `zapcore.Core` type makes it easy for third-party packages to use zap's + internals but provide a different user-facing API. +* `Logger` is now a concrete type instead of an interface. +* A less verbose (though slower) logging API is included by default. +* Package-global loggers `L` and `S` are included. +* A human-friendly console encoder is included. +* A declarative config struct allows common logger configurations to be managed + as configuration instead of code. +* Sampling is more accurate, and doesn't depend on the standard library's shared + timer heap. + +## v0.1.0-beta.1 (6 Feb 2017) + +This is a minor version, tagged to allow users to pin to the pre-1.0 APIs and +upgrade at their leisure. Since this is the first tagged release, there are no +backward compatibility concerns and all functionality is new. + +Early zap adopters should pin to the 0.1.x minor version until they're ready to +upgrade to the upcoming stable release. + +[#316]: https://github.com/uber-go/zap/pull/316 +[#309]: https://github.com/uber-go/zap/pull/309 +[#317]: https://github.com/uber-go/zap/pull/317 +[#321]:

The `SugaredLogger` +isn't any harder to use than other logging packages, and the `Logger` makes +structured logging possible in performance-sensitive contexts. Across a fleet +of Go microservices, making each application even slightly more efficient adds +up quickly. + +### Why aren't `Logger` and `SugaredLogger` interfaces? + +Unlike the familiar `io.Writer` and `http.Handler`, `Logger` and +`SugaredLogger` interfaces would include *many* methods. As [Rob Pike points +out][go-proverbs], "The bigger the interface, the weaker the abstraction." +Interfaces are also rigid — *any* change requires releasing a new major +version, since it breaks all third-party implementations. + +Making the `Logger` and `SugaredLogger` concrete types doesn't sacrifice much +abstraction, and it lets us add methods without introducing breaking changes. +Your applications should define and depend upon an interface that includes +just the methods you use. + +### Why sample application logs? + +Applications often experience runs of errors, either because of a bug or +because of a misbehaving user. Logging errors is usually a good idea, but it +can easily make this bad situation worse: not only is your application coping +with a flood of errors, it's also spending extra CPU cycles and I/O logging +those errors. Since writes are typically serialized, logging limits throughput +when you need it most. + +Sampling fixes this problem by dropping repetitive log entries. Under normal +conditions, your application writes out every entry. When similar entries are +logged hundreds or thousands of times each second, though, zap begins dropping +duplicates to preserve throughput. + +### Why do the structured logging APIs take a message in addition to fields? + +Subjectively, we find it helpful to accompany structured context with a brief +description. This isn't critical during development, but it makes debugging +and operating unfamiliar systems much easier. + +More concretely, zap's sampling algorithm uses the message to identify +duplicate entries. In our experience, this is a practical middle ground +between random sampling (which often drops the exact entry that you need while +debugging) and hashing the complete entry (which is prohibitively expensive). + +### Why include package-global loggers? + +Since so many other logging packages include a global logger, many +applications aren't designed to accept loggers as explicit parameters. +Changing function signatures is often a breaking change, so zap includes +global loggers to simplify migration. + +Avoid them where possible. + +### Why include dedicated Panic and Fatal log levels? + +In general, application code should handle errors gracefully instead of using +`panic` or `os.Exit`. However, every rule has exceptions, and it's common to +crash when an error is truly unrecoverable. To avoid losing any information +— especially the reason for the crash — the logger must flush any +buffered entries before the process exits. + +Zap makes this easy by offering `Panic` and `Fatal` logging methods that +automatically flush before exiting. Of course, this doesn't guarantee that +logs will never be lost, but it eliminates a common error. + +See the discussion in uber-go/zap#207 for more details. + +### What's `DPanic`? + +`DPanic` stands for "panic in development." In development, it logs at +`PanicLevel`; otherwise, it logs at `ErrorLevel`. `DPanic` makes it easier to +catch errors that are theoretically possible, but shouldn't actually happen, +*without* crashing in production. + +If you've ever written code like this, you need `DPanic`: + +```go +if err != nil { + panic(fmt.Sprintf("shouldn't ever get here: %v", err)) +} +``` + +## Installation + +### What does the error `expects import "go.uber.org/zap"` mean? + +Either zap was installed incorrectly or you're referencing the wrong package +name in your code. + +Zap's source code happens to be hosted on GitHub, but the [import +path][import-path] is `go.uber.org/zap`. This gives us, the project +maintainers, the freedom to move the source code if necessary. However, it +means that you need to take a little care when installing and using the +package. + +If you follow two simple rules, everything should work: install zap with `go +get -u go.uber.org/zap`, and always import it in your code with `import +"go.uber.org/zap"`. Your code shouldn't contain *any* references to +`github.com/uber-go/zap`. + +## Usage + +### Does zap support log rotation? + +Zap doesn't natively support rotating log files, since we prefer to leave this +to an external program like `logrotate`. + +However, it's easy to integrate a log rotation package like +[`gopkg.in/natefinch/lumberjack.v2`][lumberjack] as a `zapcore.WriteSyncer`. + +```go +// lumberjack.Logger is already safe for concurrent use, so we don't need to +// lock it. +w := zapcore.AddSync(&lumberjack.Logger{ + Filename: "/var/log/myapp/foo.log", + MaxSize: 500, // megabytes + MaxBackups: 3, + MaxAge: 28, // days +}) +core := zapcore.NewCore( + zapcore.NewJSONEncoder(zap.NewProductionEncoderConfig()), + w, + zap.InfoLevel, +) +logger := zap.New(core) +``` + +## Extensions + +We'd love to support every logging need within zap itself, but we're only +familiar with a handful of log ingestion systems, flag-parsing packages, and +the like.

This also means that the generated code can differ from system +to system, based on differences in the header files. + +To avoid this, if you are using the old build system, only generate the Go +files on an installation with unmodified header files. It is also important to +keep track of which version of the OS the files were generated from (ex. +Darwin 14 vs Darwin 15). This makes it easier to track the progress of changes +and have each OS upgrade correspond to a single change. + +To build the files for your current OS and architecture, make sure GOOS and +GOARCH are set correctly and run `mkall.sh`. This will generate the files for +your specific system. Running `mkall.sh -n` shows the commands that will be run. + +Requirements: bash, go + +### New Build System (currently for `GOOS == "linux"`) + +The new build system uses a Docker container to generate the go files directly +from source checkouts of the kernel and various system libraries. This means +that on any platform that supports Docker, all the files using the new build +system can be generated at once, and generated files will not change based on +what the person running the scripts has installed on their computer. + +The OS specific files for the new build system are located in the `${GOOS}` +directory, and the build is coordinated by the `${GOOS}/mkall.go` program. When +the kernel or system library updates, modify the Dockerfile at +`${GOOS}/Dockerfile` to checkout the new release of the source. + +To build all the files under the new build system, you must be on an amd64/Linux +system and have your GOOS and GOARCH set accordingly. Running `mkall.sh` will +then generate all of the files for all of the GOOS/GOARCH pairs in the new build +system. Running `mkall.sh -n` shows the commands that will be run. + +Requirements: bash, go, docker + +## Component files + +This section describes the various files used in the code generation process. +It also contains instructions on how to modify these files to add a new +architecture/OS or to add additional syscalls, types, or constants. Note that +if you are using the new build system, the scripts/programs cannot be called normally. +They must be called from within the docker container. + +### asm files + +The hand-written assembly file at `asm_${GOOS}_${GOARCH}.s` implements system +call dispatch. There are three entry points: +``` + func Syscall(trap, a1, a2, a3 uintptr) (r1, r2, err uintptr) + func Syscall6(trap, a1, a2, a3, a4, a5, a6 uintptr) (r1, r2, err uintptr) + func RawSyscall(trap, a1, a2, a3 uintptr) (r1, r2, err uintptr) +``` +The first and second are the standard ones; they differ only in how many +arguments can be passed to the kernel. The third is for low-level use by the +ForkExec wrapper. Unlike the first two, it does not call into the scheduler to +let it know that a system call is running. + +When porting Go to an new architecture/OS, this file must be implemented for +each GOOS/GOARCH pair. + +### mksysnum + +Mksysnum is a Go program located at `${GOOS}/mksysnum.go` (or `mksysnum_${GOOS}.go` +for the old system). This program takes in a list of header files containing the +syscall number declarations and parses them to produce the corresponding list of +Go numeric constants. See `zsysnum_${GOOS}_${GOARCH}.go` for the generated +constants. + +Adding new syscall numbers is mostly done by running the build on a sufficiently +new installation of the target OS (or updating the source checkouts for the +new build system). However, depending on the OS, you make need to update the +parsing in mksysnum. + +### mksyscall.go + +The `syscall.go`, `syscall_${GOOS}.go`, `syscall_${GOOS}_${GOARCH}.go` are +hand-written Go files which implement system calls (for unix, the specific OS, +or the specific OS/Architecture pair respectively) that need special handling +and list `//sys` comments giving prototypes for ones that can be generated. + +The mksyscall.go program takes the `//sys` and `//sysnb` comments and converts +them into syscalls. This requires the name of the prototype in the comment to +match a syscall number in the `zsysnum_${GOOS}_${GOARCH}.go` file. The function +prototype can be exported (capitalized) or not. + +Adding a new syscall often just requires adding a new `//sys` function prototype +with the desired arguments and a capitalized name so it is exported. However, if +you want the interface to the syscall to be different, often one will make an +unexported `//sys` prototype, an then write a custom wrapper in +`syscall_${GOOS}.go`. + +### types files + +For each OS, there is a hand-written Go file at `${GOOS}/types.go` (or +`types_${GOOS}.go` on the old system). This file includes standard C headers and +creates Go type aliases to the corresponding C types. The file is then fed +through godef to get the Go compatible definitions. Finally, the generated code +is fed though mkpost.go to format the code correctly and remove any hidden or +private identifiers. This cleaned-up code is written to +`ztypes_${GOOS}_${GOARCH}.go`. + +The hardest part about preparing this file is figuring out which headers to +include and which symbols need to be `#define`d to get the actual data +structures that pass through to the kernel system calls. Some C libraries +preset alternate versions for binary compatibility and translate them on the +way in and out of system calls, but there is almost always a `#define` that can +get the real ones. +See `types_darwin.go` and `linux/types.go` for examples. + +To add a new type, add in the necessary include statement at the top of the +file (if it is not already there) and add in a type alias line. Note that if +your type is significantly different on different architectures, you may need +some `#if/#elif` macros in your include statements. + +### mkerrors.sh + +This script is used to generate the system's various constants. This doesn't +just include the error numbers and error strings, but also the signal numbers +an a wide variety of miscellaneous constants. The constants come from the list +of include files in the `includes_${uname}` variable. A regex then picks out +the desired `#define` statements, and generates the corresponding Go constants. +The error numbers and strings are generated from `#include `, and the +signal numbers and strings are generated from `#include `. All of +these constants are written to `zerrors_${GOOS}_${GOARCH}.go` via a C program, +`_errors.c`, which prints out all the constants. + +To add a constant, add the header that includes it to the appropriate variable. +Then, edit the regex (if necessary) to match the desired constant. Avoid making +the regex too broad to avoid matching unintended constants. + + +## Generated files + +### `zerror_${GOOS}_${GOARCH}.go` + +A file containing all of the system's generated error numbers, error strings, +signal numbers, and constants. Generated by `mkerrors.sh` (see above). + +### `zsyscall_${GOOS}_${GOARCH}.go` + +A file containing all the generated syscalls for a specific GOOS and GOARCH. +Generated by `mksyscall.go` (see above). + +### `zsysnum_${GOOS}_${GOARCH}.go` + +A list of numeric constants for all the syscall number of the specific GOOS +and GOARCH. Generated by mksysnum (see above). + +### `ztypes_${GOOS}_${GOARCH}.go` + +A file containing Go types for passing into (or returning from) syscalls. +Generated by godefs and the types file (see above). diff --git a/vendor/golang.org/x/sys/unix/mkall.sh b/vendor/golang.org/x/sys/unix/mkall.sh new file mode 100644 index 000000000..fa0c69b9d --- /dev/null +++ b/vendor/golang.org/x/sys/unix/mkall.sh @@ -0,0 +1,229 @@ +#!/usr/bin/env bash +# Copyright 2009 The Go Authors.

This means that it effectively reuses the JSON struct tags as well as the custom JSON methods `MarshalJSON` and `UnmarshalJSON` unlike go-yaml. For a detailed overview of the rationale behind this method, [see this blog post](http://ghodss.com/2014/the-right-way-to-handle-yaml-in-golang/). + +## Compatibility + +This package uses [go-yaml](https://github.com/go-yaml/yaml) and therefore supports [everything go-yaml supports](https://github.com/go-yaml/yaml#compatibility). + +## Caveats + +**Caveat #1:** When using `yaml.Marshal` and `yaml.Unmarshal`, binary data should NOT be preceded with the `!!binary` YAML tag. If you do, go-yaml will convert the binary data from base64 to native binary data, which is not compatible with JSON. You can still use binary in your YAML files though - just store them without the `!!binary` tag and decode the base64 in your code (e.g. in the custom JSON methods `MarshalJSON` and `UnmarshalJSON`). This also has the benefit that your YAML and your JSON binary data will be decoded exactly the same way. As an example: + +``` +BAD: + exampleKey: !!binary gIGC + +GOOD: + exampleKey: gIGC +... and decode the base64 data in your code. +``` + +**Caveat #2:** When using `YAMLToJSON` directly, maps with keys that are maps will result in an error since this is not supported by JSON. This error will occur in `Unmarshal` as well since you can't unmarshal map keys anyways since struct fields can't be keys. + +## Installation and usage + +To install, run: + +``` +$ go get github.com/ghodss/yaml +``` + +And import using: + +``` +import "github.com/ghodss/yaml" +``` + +Usage is very similar to the JSON library: + +```go +package main + +import ( + "fmt" + + "github.com/ghodss/yaml" +) + +type Person struct { + Name string `json:"name"` // Affects YAML field names too. + Age int `json:"age"` +} + +func main() { + // Marshal a Person struct to YAML. + p := Person{"John", 30} + y, err := yaml.Marshal(p) + if err != nil { + fmt.Printf("err: %v\n", err) + return + } + fmt.Println(string(y)) + /* Output: + age: 30 + name: John + */ + + // Unmarshal the YAML back into a Person struct. + var p2 Person + err = yaml.Unmarshal(y, &p2) + if err != nil { + fmt.Printf("err: %v\n", err) + return + } + fmt.Println(p2) + /* Output: + {John 30} + */ +} +``` + +`yaml.YAMLToJSON` and `yaml.JSONToYAML` methods are also available: + +```go +package main + +import ( + "fmt" + + "github.com/ghodss/yaml" +) + +func main() { + j := []byte(`{"name": "John", "age": 30}`) + y, err := yaml.JSONToYAML(j) + if err != nil { + fmt.Printf("err: %v\n", err) + return + } + fmt.Println(string(y)) + /* Output: + name: John + age: 30 + */ + j2, err := yaml.YAMLToJSON(y) + if err != nil { + fmt.Printf("err: %v\n", err) + return + } + fmt.Println(string(j2)) + /* Output: + {"age":30,"name":"John"} + */ +} +``` diff --git a/vendor/sigs.k8s.io/yaml/RELEASE.md b/vendor/sigs.k8s.io/yaml/RELEASE.md new file mode 100644 index 000000000..6b642464e --- /dev/null +++ b/vendor/sigs.k8s.io/yaml/RELEASE.md @@ -0,0 +1,9 @@ +# Release Process + +The `yaml` Project is released on an as-needed basis.
