See the -sections below for further details on formatting and configuration options. - -To dump a variable with full newlines, indentation, type, and pointer -information use Dump, Fdump, or Sdump: - spew.Dump(myVar1, myVar2, ...) - spew.Fdump(someWriter, myVar1, myVar2, ...) - str := spew.Sdump(myVar1, myVar2, ...) - -Alternatively, if you would prefer to use format strings with a compacted inline -printing style, use the convenience wrappers Printf, Fprintf, etc with -%v (most compact), %+v (adds pointer addresses), %#v (adds types), or -%#+v (adds types and pointer addresses): - spew.Printf("myVar1: %v -- myVar2: %+v", myVar1, myVar2) - spew.Printf("myVar3: %#v -- myVar4: %#+v", myVar3, myVar4) - spew.Fprintf(someWriter, "myVar1: %v -- myVar2: %+v", myVar1, myVar2) - spew.Fprintf(someWriter, "myVar3: %#v -- myVar4: %#+v", myVar3, myVar4) - -Configuration Options - -Configuration of spew is handled by fields in the ConfigState type. For -convenience, all of the top-level functions use a global state available -via the spew.Config global. - -It is also possible to create a ConfigState instance that provides methods -equivalent to the top-level functions. This allows concurrent configuration -options. See the ConfigState documentation for more details. - -The following configuration options are available: - * Indent - String to use for each indentation level for Dump functions. - It is a single space by default. A popular alternative is "\t". - - * MaxDepth - Maximum number of levels to descend into nested data structures. - There is no limit by default. - - * DisableMethods - Disables invocation of error and Stringer interface methods. - Method invocation is enabled by default. - - * DisablePointerMethods - Disables invocation of error and Stringer interface methods on types - which only accept pointer receivers from non-pointer variables. - Pointer method invocation is enabled by default. - - * DisablePointerAddresses - DisablePointerAddresses specifies whether to disable the printing of - pointer addresses. This is useful when diffing data structures in tests. - - * DisableCapacities - DisableCapacities specifies whether to disable the printing of - capacities for arrays, slices, maps and channels. This is useful when - diffing data structures in tests. - - * ContinueOnMethod - Enables recursion into types after invoking error and Stringer interface - methods. Recursion after method invocation is disabled by default. - - * SortKeys - Specifies map keys should be sorted before being printed. Use - this to have a more deterministic, diffable output. Note that - only native types (bool, int, uint, floats, uintptr and string) - and types which implement error or Stringer interfaces are - supported with other types sorted according to the - reflect.Value.String() output which guarantees display - stability. Natural map order is used by default. - - * SpewKeys - Specifies that, as a last resort attempt, map keys should be - spewed to strings and sorted by those strings. This is only - considered if SortKeys is true. - -Dump Usage - -Simply call spew.Dump with a list of variables you want to dump: - - spew.Dump(myVar1, myVar2, ...) - -You may also call spew.Fdump if you would prefer to output to an arbitrary -io.Writer.

The data added to the message adds "context" about the log event that can be critical for debugging as well as myriad other purposes. An example of this is below: - -```go -package main - -import ( - "github.com/rs/zerolog" - "github.com/rs/zerolog/log" -) - -func main() { - zerolog.TimeFieldFormat = "" - - log.Debug(). - Str("Scale", "833 cents"). - Float64("Interval", 833.09). - Msg("Fibonacci is everywhere") -} - -// Output: {"time":1524104936,"level":"debug","Scale":"833 cents","Interval":833.09,"message":"Fibonacci is everywhere"} -``` - -> You'll note in the above example that when adding contextual fields, the fields are strongly typed. You can find the full list of supported fields [here](#standard-types) - -### Leveled Logging - -#### Simple Leveled Logging Example - -```go -package main - -import ( - "github.com/rs/zerolog" - "github.com/rs/zerolog/log" -) - -func main() { - zerolog.TimeFieldFormat = "" - - log.Info().Msg("hello world") -} - -// Output: {"time":1516134303,"level":"info","message":"hello world"} -``` - -> It is very important to note that when using the **zerolog** chaining API, as shown above (`log.Info().Msg("hello world"`), the chain must have either the `Msg` or `Msgf` method call. If you forget to add either of these, the log will not occur and there is no compile time error to alert you of this. - -**zerolog** allows for logging at the following levels (from highest to lowest): - -* panic (`zerolog.PanicLevel`, 5) -* fatal (`zerolog.FatalLevel`, 4) -* error (`zerolog.ErrorLevel`, 3) -* warn (`zerolog.WarnLevel`, 2) -* info (`zerolog.InfoLevel`, 1) -* debug (`zerolog.DebugLevel`, 0) - -You can set the Global logging level to any of these options using the `SetGlobalLevel` function in the zerolog package, passing in one of the given constants above, e.g. `zerolog.InfoLevel` would be the "info" level. Whichever level is chosen, all logs with a level greater than or equal to that level will be written. To turn off logging entirely, pass the `zerolog.Disabled` constant. - -#### Setting Global Log Level - -This example uses command-line flags to demonstrate various outputs depending on the chosen log level. - -```go -package main - -import ( - "flag" - - "github.com/rs/zerolog" - "github.com/rs/zerolog/log" -) - -func main() { - zerolog.TimeFieldFormat = "" - debug := flag.Bool("debug", false, "sets log level to debug") - - flag.Parse() - - // Default level for this example is info, unless debug flag is present - zerolog.SetGlobalLevel(zerolog.InfoLevel) - if *debug { - zerolog.SetGlobalLevel(zerolog.DebugLevel) - } - - log.Debug().Msg("This message appears only when log level set to Debug") - log.Info().Msg("This message appears when log level set to Debug or Info") - - if e := log.Debug(); e.Enabled() { - // Compute log output only if enabled. - value := "bar" - e.Str("foo", value).Msg("some debug message") - } -} -``` - -Info Output (no flag) - -```bash -$ ./logLevelExample -{"time":1516387492,"level":"info","message":"This message appears when log level set to Debug or Info"} -``` - -Debug Output (debug flag set) - -```bash -$ ./logLevelExample -debug -{"time":1516387573,"level":"debug","message":"This message appears only when log level set to Debug"} -{"time":1516387573,"level":"info","message":"This message appears when log level set to Debug or Info"} -{"time":1516387573,"level":"debug","foo":"bar","message":"some debug message"} -``` - -#### Logging without Level or Message - -You may choose to log without a specific level by using the `Log` method. You may also write without a message by setting an empty string in the `msg string` parameter of the `Msg` method. Both are demonstrated in the example below. - -```go -package main - -import ( - "github.com/rs/zerolog" - "github.com/rs/zerolog/log" -) - -func main() { - zerolog.TimeFieldFormat = "" - - log.Log(). - Str("foo", "bar"). - Msg("") -} - -// Output: {"time":1494567715,"foo":"bar"} -``` - -#### Logging Fatal Messages - -```go -package main - -import ( - "errors" - - "github.com/rs/zerolog" - "github.com/rs/zerolog/log" -) - -func main() { - err := errors.New("A repo man spends his life getting into tense situations") - service := "myservice" - - zerolog.TimeFieldFormat = "" - - log.Fatal(). - Err(err). - Str("service", service). - Msgf("Cannot start %s", service) -} - -// Output: {"time":1516133263,"level":"fatal","error":"A repo man spends his life getting into tense situations","service":"myservice","message":"Cannot start myservice"} -// exit status 1 -``` - -> NOTE: Using `Msgf` generates one allocation even when the logger is disabled. - -### Create logger instance to manage different outputs - -```go -logger := zerolog.New(os.Stderr).With().Timestamp().Logger() - -logger.Info().Str("foo", "bar").Msg("hello world") - -// Output: {"level":"info","time":1494567715,"message":"hello world","foo":"bar"} -``` - -### Sub-loggers let you chain loggers with additional context - -```go -sublogger := log.With(). - Str("component", "foo"). - Logger() -sublogger.Info().Msg("hello world") - -// Output: {"level":"info","time":1494567715,"message":"hello world","component":"foo"} -``` - -### Pretty logging - -To log a human-friendly, colorized output, use `zerolog.ConsoleWriter`: - -```go -log.Logger = log.Output(zerolog.ConsoleWriter{Out: os.Stderr}) - -log.Info().Str("foo", "bar").Msg("Hello world") - -// Output: 3:04PM INF Hello World foo=bar -``` - -To customize the configuration and formatting: - -```go -output := zerolog.ConsoleWriter{Out: os.Stdout, TimeFormat: time.RFC3339} -output.FormatLevel = func(i interface{}) string { - return strings.ToUpper(fmt.Sprintf("| %-6s|", i)) -} -output.FormatMessage = func(i interface{}) string { - return fmt.Sprintf("***%s****", i) -} -output.FormatFieldName = func(i interface{}) string { - return fmt.Sprintf("%s:", i) -} -output.FormatFieldValue = func(i interface{}) string { - return strings.ToUpper(fmt.Sprintf("%s", i)) -} - -log := zerolog.New(output).With().Timestamp().Logger() - -log.Info().Str("foo", "bar").Msg("Hello World") - -// Output: 2006-01-02T15:04:05Z07:00 | INFO | ***Hello World**** foo:BAR -``` - -### Sub dictionary - -```go -log.Info(). - Str("foo", "bar"). - Dict("dict", zerolog.Dict(). - Str("bar", "baz"). - Int("n", 1), - ).Msg("hello world") - -// Output: {"level":"info","time":1494567715,"foo":"bar","dict":{"bar":"baz","n":1},"message":"hello world"} -``` - -### Customize automatic field names - -```go -zerolog.TimestampFieldName = "t" -zerolog.LevelFieldName = "l" -zerolog.MessageFieldName = "m" - -log.Info().Msg("hello world") - -// Output: {"l":"info","t":1494567715,"m":"hello world"} -``` - -### Add contextual fields to the global logger - -```go -log.Logger = log.With().Str("foo", "bar").Logger() -``` - -### Add file and line number to log - -```go -log.Logger = log.With().Caller().Logger() -log.Info().Msg("hello world") - -// Output: {"level": "info", "message": "hello world", "caller": "/go/src/your_project/some_file:21"} -``` - - -### Thread-safe, lock-free, non-blocking writer - -If your writer might be slow or not thread-safe and you need your log producers to never get slowed down by a slow writer, you can use a `diode.Writer` as follow: - -```go -wr := diode.NewWriter(os.Stdout, 1000, 10*time.Millisecond, func(missed int) { - fmt.Printf("Logger Dropped %d messages", missed) - }) -log := zerolog.New(w) -log.Print("test") -``` - -You will need to install `code.cloudfoundry.org/go-diodes` to use this feature. - -### Log Sampling - -```go -sampled := log.Sample(&zerolog.BasicSampler{N: 10}) -sampled.Info().Msg("will be logged every 10 messages") - -// Output: {"time":1494567715,"level":"info","message":"will be logged every 10 messages"} -``` - -More advanced sampling: - -```go -// Will let 5 debug messages per period of 1 second. -// Over 5 debug message, 1 every 100 debug messages are logged. -// Other levels are not sampled. -sampled := log.Sample(zerolog.LevelSampler{ - DebugSampler: &zerolog.BurstSampler{ - Burst: 5, - Period: 1*time.Second, - NextSampler: &zerolog.BasicSampler{N: 100}, - }, -}) -sampled.Debug().Msg("hello world") - -// Output: {"time":1494567715,"level":"debug","message":"hello world"} -``` - -### Hooks - -```go -type SeverityHook struct{} - -func (h SeverityHook) Run(e *zerolog.Event, level zerolog.Level, msg string) { - if level != zerolog.NoLevel { - e.Str("severity", level.String()) - } -} - -hooked := log.Hook(SeverityHook{}) -hooked.Warn().Msg("") - -// Output: {"level":"warn","severity":"warn"} -``` - -### Pass a sub-logger by context - -```go -ctx := log.With().Str("component", "module").Logger().WithContext(ctx) - -log.Ctx(ctx).Info().Msg("hello world") - -// Output: {"component":"module","level":"info","message":"hello world"} -``` - -### Set as standard logger output - -```go -log := zerolog.New(os.Stdout).With(). - Str("foo", "bar"). - Logger() - -stdlog.SetFlags(0) -stdlog.SetOutput(log) - -stdlog.Print("hello world") - -// Output: {"foo":"bar","message":"hello world"} -``` - -### Integration with `net/http` - -The `github.com/rs/zerolog/hlog` package provides some helpers to integrate zerolog with `http.Handler`. - -In this example we use [alice](https://github.com/justinas/alice) to install logger for better readability. - -```go -log := zerolog.New(os.Stdout).With(). - Timestamp(). - Str("role", "my-service"). - Str("host", host). - Logger() - -c := alice.New() - -// Install the logger handler with default output on the console -c = c.Append(hlog.NewHandler(log)) - -// Install some provided extra handler to set some request's context fields. -// Thanks to those handler, all our logs will come with some pre-populated fields. -c = c.Append(hlog.AccessHandler(func(r *http.Request, status, size int, duration time.Duration) { - hlog.FromRequest(r).Info(). - Str("method", r.Method). - Str("url", r.URL.String()). - Int("status", status). - Int("size", size). - Dur("duration", duration). - Msg("") -})) -c = c.Append(hlog.RemoteAddrHandler("ip")) -c = c.Append(hlog.UserAgentHandler("user_agent")) -c = c.Append(hlog.RefererHandler("referer")) -c = c.Append(hlog.RequestIDHandler("req_id", "Request-Id")) - -// Here is your final handler -h := c.Then(http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) { - // Get the logger from the request's context. You can safely assume it - // will be always there: if the handler is removed, hlog.FromRequest - // will return a no-op logger. - hlog.FromRequest(r).Info(). - Str("user", "current user"). - Str("status", "ok"). - Msg("Something happened") - - // Output: {"level":"info","time":"2001-02-03T04:05:06Z","role":"my-service","host":"local-hostname","req_id":"b4g0l5t6tfid6dtrapu0","user":"current user","status":"ok","message":"Something happened"} -})) -http.Handle("/", h) - -if err := http.ListenAndServe(":8080", nil); err != nil { - log.Fatal().Err(err).Msg("Startup failed") -} -``` - -## Global Settings - -Some settings can be changed and will by applied to all loggers: - -* `log.Logger`: You can set this value to customize the global logger (the one used by package level methods). -* `zerolog.SetGlobalLevel`: Can raise the minimum level of all loggers. Set this to `zerolog.Disabled` to disable logging altogether (quiet mode). -* `zerolog.DisableSampling`: If argument is `true`, all sampled loggers will stop sampling and issue 100% of their log events. -* `zerolog.TimestampFieldName`: Can be set to customize `Timestamp` field name. -* `zerolog.LevelFieldName`: Can be set to customize level field name. -* `zerolog.MessageFieldName`: Can be set to customize message field name. -* `zerolog.ErrorFieldName`: Can be set to customize `Err` field name. -* `zerolog.TimeFieldFormat`: Can be set to customize `Time` field value formatting. If set with an empty string, times are formated as UNIX timestamp. - // DurationFieldUnit defines the unit for time.Duration type fields added - // using the Dur method. -* `DurationFieldUnit`: Sets the unit of the fields added by `Dur` (default: `time.Millisecond`). -* `DurationFieldInteger`: If set to true, `Dur` fields are formatted as integers instead of floats. -* `ErrorHandler`: Called whenever zerolog fails to write an event on its output. If not set, an error is printed on the stderr. This handler must be thread safe and non-blocking. - -## Field Types - -### Standard Types - -* `Str` -* `Bool` -* `Int`, `Int8`, `Int16`, `Int32`, `Int64` -* `Uint`, `Uint8`, `Uint16`, `Uint32`, `Uint64` -* `Float32`, `Float64` - -### Advanced Fields - -* `Err`: Takes an `error` and render it as a string using the `zerolog.ErrorFieldName` field name. -* `Timestamp`: Insert a timestamp field with `zerolog.TimestampFieldName` field name and formatted using `zerolog.TimeFieldFormat`. -* `Time`: Adds a field with the time formated with the `zerolog.TimeFieldFormat`. -* `Dur`: Adds a field with a `time.Duration`. -* `Dict`: Adds a sub-key/value as a field of the event. -* `Interface`: Uses reflection to marshal the type. - -## Binary Encoding - -In addition to the default JSON encoding, `zerolog` can produce binary logs using [CBOR](http://cbor.io) encoding. The choice of encoding can be decided at compile time using the build tag `binary_log` as follows: - -```bash -go build -tags binary_log . -``` - -To Decode binary encoded log files you can use any CBOR decoder.

-Important points: - -* Fasthttp works with [RequestHandler functions](https://godoc.org/github.com/valyala/fasthttp#RequestHandler) -instead of objects implementing [Handler interface](https://golang.org/pkg/net/http/#Handler). -Fortunately, it is easy to pass bound struct methods to fasthttp: - - ```go - type MyHandler struct { - foobar string - } - - // request handler in net/http style, i.e. method bound to MyHandler struct. - func (h *MyHandler) HandleFastHTTP(ctx *fasthttp.RequestCtx) { - // notice that we may access MyHandler properties here - see h.foobar. - fmt.Fprintf(ctx, "Hello, world! Requested path is %q. Foobar is %q", - ctx.Path(), h.foobar) - } - - // request handler in fasthttp style, i.e. just plain function. - func fastHTTPHandler(ctx *fasthttp.RequestCtx) { - fmt.Fprintf(ctx, "Hi there! RequestURI is %q", ctx.RequestURI()) - } - - // pass bound struct method to fasthttp - myHandler := &MyHandler{ - foobar: "foobar", - } - fasthttp.ListenAndServe(":8080", myHandler.HandleFastHTTP) - - // pass plain function to fasthttp - fasthttp.ListenAndServe(":8081", fastHTTPHandler) - ``` - -* The [RequestHandler](https://godoc.org/github.com/valyala/fasthttp#RequestHandler) -accepts only one argument - [RequestCtx](https://godoc.org/github.com/valyala/fasthttp#RequestCtx). -It contains all the functionality required for http request processing -and response writing. Below is an example of a simple request handler conversion -from net/http to fasthttp. - - ```go - // net/http request handler - requestHandler := func(w http.ResponseWriter, r *http.Request) { - switch r.URL.Path { - case "/foo": - fooHandler(w, r) - case "/bar": - barHandler(w, r) - default: - http.Error(w, "Unsupported path", http.StatusNotFound) - } - } - ``` - - ```go - // the corresponding fasthttp request handler - requestHandler := func(ctx *fasthttp.RequestCtx) { - switch string(ctx.Path()) { - case "/foo": - fooHandler(ctx) - case "/bar": - barHandler(ctx) - default: - ctx.Error("Unsupported path", fasthttp.StatusNotFound) - } - } - ``` - -* Fasthttp allows setting response headers and writing response body -in an arbitrary order. There is no 'headers first, then body' restriction -like in net/http. The following code is valid for fasthttp: - - ```go - requestHandler := func(ctx *fasthttp.RequestCtx) { - // set some headers and status code first - ctx.SetContentType("foo/bar") - ctx.SetStatusCode(fasthttp.StatusOK) - - // then write the first part of body - fmt.Fprintf(ctx, "this is the first part of body\n") - - // then set more headers - ctx.Response.Header.Set("Foo-Bar", "baz") - - // then write more body - fmt.Fprintf(ctx, "this is the second part of body\n") - - // then override already written body - ctx.SetBody([]byte("this is completely new body contents")) - - // then update status code - ctx.SetStatusCode(fasthttp.StatusNotFound) - - // basically, anything may be updated many times before - // returning from RequestHandler. - // - // Unlike net/http fasthttp doesn't put response to the wire until - // returning from RequestHandler. - } - ``` - -* Fasthttp doesn't provide [ServeMux](https://golang.org/pkg/net/http/#ServeMux), -but there are more powerful third-party routers and web frameworks -with fasthttp support: - - * [Iris](https://github.com/kataras/iris) - * [fasthttp-routing](https://github.com/qiangxue/fasthttp-routing) - * [fasthttprouter](https://github.com/buaazp/fasthttprouter) - * [lu](https://github.com/vincentLiuxiang/lu) - - Net/http code with simple ServeMux is trivially converted to fasthttp code: - - ```go - // net/http code - - m := &http.ServeMux{} - m.HandleFunc("/foo", fooHandlerFunc) - m.HandleFunc("/bar", barHandlerFunc) - m.Handle("/baz", bazHandler) - - http.ListenAndServe(":80", m) - ``` - - ```go - // the corresponding fasthttp code - m := func(ctx *fasthttp.RequestCtx) { - switch string(ctx.Path()) { - case "/foo": - fooHandlerFunc(ctx) - case "/bar": - barHandlerFunc(ctx) - case "/baz": - bazHandler.HandlerFunc(ctx) - default: - ctx.Error("not found", fasthttp.StatusNotFound) - } - } - - fasthttp.ListenAndServe(":80", m) -

- * Wrap RequestHandler into [TimeoutHandler](https://godoc.org/github.com/valyala/fasthttp#TimeoutHandler). - * Call [TimeoutError](https://godoc.org/github.com/valyala/fasthttp#RequestCtx.TimeoutError) - before returning from RequestHandler if there are references to RequestCtx or to its' members. - See [the example](https://godoc.org/github.com/valyala/fasthttp#example-RequestCtx-TimeoutError) - for more details. - -Use this brilliant tool - [race detector](http://blog.golang.org/race-detector) - -for detecting and eliminating data races in your program. If you detected -data race related to fasthttp in your program, then there is high probability -you forgot calling [TimeoutError](https://godoc.org/github.com/valyala/fasthttp#RequestCtx.TimeoutError) -before returning from [RequestHandler](https://godoc.org/github.com/valyala/fasthttp#RequestHandler). - -* Blind switching from net/http to fasthttp won't give you performance boost. -While fasthttp is optimized for speed, its' performance may be easily saturated -by slow [RequestHandler](https://godoc.org/github.com/valyala/fasthttp#RequestHandler). -So [profile](http://blog.golang.org/profiling-go-programs) and optimize your -code after switching to fasthttp. For instance, use [quicktemplate](https://github.com/valyala/quicktemplate) -instead of [html/template](https://golang.org/pkg/html/template/). - -* See also [fasthttputil](https://godoc.org/github.com/valyala/fasthttp/fasthttputil), -[fasthttpadaptor](https://godoc.org/github.com/valyala/fasthttp/fasthttpadaptor) and -[expvarhandler](https://godoc.org/github.com/valyala/fasthttp/expvarhandler). - - -# Performance optimization tips for multi-core systems - -* Use [reuseport](https://godoc.org/github.com/valyala/fasthttp/reuseport) listener. -* Run a separate server instance per CPU core with GOMAXPROCS=1. -* Pin each server instance to a separate CPU core using [taskset](http://linux.die.net/man/1/taskset). -* Ensure the interrupts of multiqueue network card are evenly distributed between CPU cores. - See [this article](https://blog.cloudflare.com/how-to-achieve-low-latency/) for details. -* Use Go 1.6 as it provides some considerable performance improvements. - - -# Fasthttp best practices - -* Do not allocate objects and `[]byte` buffers - just reuse them as much - as possible. Fasthttp API design encourages this. -* [sync.Pool](https://golang.org/pkg/sync/#Pool) is your best friend. -* [Profile your program](http://blog.golang.org/profiling-go-programs) - in production. - `go tool pprof --alloc_objects your-program mem.pprof` usually gives better - insights for optimization opportunities than `go tool pprof your-program cpu.pprof`. -* Write [tests and benchmarks](https://golang.org/pkg/testing/) for hot paths. -* Avoid conversion between `[]byte` and `string`, since this may result in memory - allocation+copy. Fasthttp API provides functions for both `[]byte` and `string` - - use these functions instead of converting manually between `[]byte` and `string`. - There are some exceptions - see [this wiki page](https://github.com/golang/go/wiki/CompilerOptimizations#string-and-byte) - for more details. -* Verify your tests and production code under - [race detector](https://golang.org/doc/articles/race_detector.html) on a regular basis. -* Prefer [quicktemplate](https://github.com/valyala/quicktemplate) instead of - [html/template](https://golang.org/pkg/html/template/) in your webserver. - - -# Tricks with `[]byte` buffers - -The following tricks are used by fasthttp. Use them in your code too. - -* Standard Go functions accept nil buffers -```go -var ( - // both buffers are uninitialized - dst []byte - src []byte -) -dst = append(dst, src...) // is legal if dst is nil and/or src is nil -copy(dst, src) // is legal if dst is nil and/or src is nil -(string(src) == "") // is true if src is nil -(len(src) == 0) // is true if src is nil -src = src[:0] // works like a charm with nil src - -// this for loop doesn't panic if src is nil -for i, ch := range src { - doSomething(i, ch) -} -``` - -So throw away nil checks for `[]byte` buffers from you code. For example, -```go -srcLen := 0 -if src != nil { - srcLen = len(src) -} -``` - -becomes - -```go -srcLen := len(src) -``` - -* String may be appended to `[]byte` buffer with `append` -```go -dst = append(dst, "foobar"...) -``` - -* `[]byte` buffer may be extended to its' capacity. -```go -buf := make([]byte, 100) -a := buf[:10] // len(a) == 10, cap(a) == 100. -b := a[:100] // is valid, since cap(a) == 100. -``` - -* All fasthttp functions accept nil `[]byte` buffer -```go -statusCode, body, err := fasthttp.Get(nil, "http://google.com/") -uintBuf := fasthttp.AppendUint(nil, 1234) -``` - -# Related projects - - * [fasthttp-contrib](https://github.com/fasthttp-contrib) - various useful - helpers for projects based on fasthttp. - * [iris](https://github.com/kataras/iris) - web application framework built - on top of fasthttp.

So the server must create a new request object per each request instead - of reusing existing objects like fasthttp does. - * net/http headers are stored in a `map[string][]string`. So the server - must parse all the headers, convert them from `[]byte` to `string` and put - them into the map before calling user-provided request handler. - This all requires unnecessary memory allocations avoided by fasthttp. - * net/http client API requires creating a new response object per each request. - -* *Why fasthttp API is incompatible with net/http?* - - Because net/http API limits many optimization opportunities. See the answer - above for more details. Also certain net/http API parts are suboptimal - for use: - * Compare [net/http connection hijacking](https://golang.org/pkg/net/http/#Hijacker) - to [fasthttp connection hijacking](https://godoc.org/github.com/valyala/fasthttp#RequestCtx.Hijack). - * Compare [net/http Request.Body reading](https://golang.org/pkg/net/http/#Request) - to [fasthttp request body reading](https://godoc.org/github.com/valyala/fasthttp#RequestCtx.PostBody). - -* *Why fasthttp doesn't support HTTP/2.0 and WebSockets?* - - There are [plans](TODO) for adding HTTP/2.0 and WebSockets support - in the future. - In the mean time, third parties may use [RequestCtx.Hijack](https://godoc.org/github.com/valyala/fasthttp#RequestCtx.Hijack) - for implementing these goodies. See [the first third-party websocket implementation on the top of fasthttp](https://github.com/leavengood/websocket). - -* *Are there known net/http advantages comparing to fasthttp?* - - Yes: - * net/http supports [HTTP/2.0 starting from go1.6](https://http2.golang.org/). - * net/http API is stable, while fasthttp API constantly evolves. - * net/http handles more HTTP corner cases. - * net/http should contain less bugs, since it is used and tested by much - wider audience. - * net/http works on Go older than 1.5. - -* *Why fasthttp API prefers returning `[]byte` instead of `string`?* - - Because `[]byte` to `string` conversion isn't free - it requires memory - allocation and copy. Feel free wrapping returned `[]byte` result into - `string()` if you prefer working with strings instead of byte slices. - But be aware that this has non-zero overhead. - -* *Which GO versions are supported by fasthttp?* - - Go1.5+. Older versions won't be supported, since their standard package - [miss useful functions](https://github.com/valyala/fasthttp/issues/5). - -* *Please provide real benchmark data and sever information* - - See [this issue](https://github.com/valyala/fasthttp/issues/4). - -* *Are there plans to add request routing to fasthttp?* - - There are no plans to add request routing into fasthttp. - Use third-party routers and web frameworks with fasthttp support: - - * [Iris](https://github.com/kataras/iris) - * [fasthttp-routing](https://github.com/qiangxue/fasthttp-routing) - * [fasthttprouter](https://github.com/buaazp/fasthttprouter) - * [gramework](https://github.com/gramework/gramework) - * [lu](https://github.com/vincentLiuxiang/lu) - - See also [this issue](https://github.com/valyala/fasthttp/issues/9) for more info. - -* *I detected data race in fasthttp!* - - Cool!

The scoring obfuscates the importance of -// the various factors considered, making the algorithm harder to understand. Using -// scoring also requires the full score to be computed for each pair of tags. -// -// We will use a different algorithm which aims to have the following properties: -// - clarity on the precedence of the various selection factors, and -// - improved performance by allowing early termination of a comparison. -// -// Matching algorithm (overview) -// Input: -// - supported: a set of supported tags -// - default: the default tag to return in case there is no match -// - desired: list of desired tags, ordered by preference, starting with -// the most-preferred. -// -// Algorithm: -// 1) Set the best match to the lowest confidence level -// 2) For each tag in "desired": -// a) For each tag in "supported": -// 1) compute the match between the two tags. -// 2) if the match is better than the previous best match, replace it -// with the new match. (see next section) -// b) if the current best match is Exact and pin is true the result will be -// frozen to the language found thusfar, although better matches may -// still be found for the same language. -// 3) If the best match so far is below a certain threshold, return "default". -// -// Ranking: -// We use two phases to determine whether one pair of tags are a better match -// than another pair of tags. First, we determine a rough confidence level. If the -// levels are different, the one with the highest confidence wins. -// Second, if the rough confidence levels are identical, we use a set of tie-breaker -// rules. -// -// The confidence level of matching a pair of tags is determined by finding the -// lowest confidence level of any matches of the corresponding subtags (the -// result is deemed as good as its weakest link). -// We define the following levels: -// Exact - An exact match of a subtag, before adding likely subtags. -// MaxExact - An exact match of a subtag, after adding likely subtags. -// [See Note 2]. -// High - High level of mutual intelligibility between different subtag -// variants. -// Low - Low level of mutual intelligibility between different subtag -// variants. -// No - No mutual intelligibility. -// -// The following levels can occur for each type of subtag: -// Base: Exact, MaxExact, High, Low, No -// Script: Exact, MaxExact [see Note 3], Low, No -// Region: Exact, MaxExact, High -// Variant: Exact, High -// Private: Exact, No -// -// Any result with a confidence level of Low or higher is deemed a possible match. -// Once a desired tag matches any of the supported tags with a level of MaxExact -// or higher, the next desired tag is not considered (see Step 2.b). -// Note that CLDR provides languageMatching data that defines close equivalence -// classes for base languages, scripts and regions. -// -// Tie-breaking -// If we get the same confidence level for two matches, we apply a sequence of -// tie-breaking rules. The first that succeeds defines the result. The rules are -// applied in the following order. -// 1) Original language was defined and was identical. -// 2) Original region was defined and was identical. -// 3) Distance between two maximized regions was the smallest. -// 4) Original script was defined and was identical. -// 5) Distance from want tag to have tag using the parent relation [see Note 5.] -// If there is still no winner after these rules are applied, the first match -// found wins. -// -// Notes: -// [2] In practice, as matching of Exact is done in a separate phase from -// matching the other levels, we reuse the Exact level to mean MaxExact in -// the second phase. As a consequence, we only need the levels defined by -// the Confidence type. The MaxExact confidence level is mapped to High in -// the public API. -// [3] We do not differentiate between maximized script values that were derived -// from suppressScript versus most likely tag data. We determined that in -// ranking the two, one ranks just after the other. Moreover, the two cannot -// occur concurrently. As a consequence, they are identical for practical -// purposes. -// [4] In case of deprecated, macro-equivalents and legacy mappings, we assign -// the MaxExact level to allow iw vs he to still be a closer match than -// en-AU vs en-US, for example. -// [5] In CLDR a locale inherits fields that are unspecified for this locale -// from its parent. Therefore, if a locale is a parent of another locale, -// it is a strong measure for closeness, especially when no other tie -// breaker rule applies. One could also argue it is inconsistent, for -// example, when pt-AO matches pt (which CLDR equates with pt-BR), even -// though its parent is pt-PT according to the inheritance rules. -// -// Implementation Details: -// There are several performance considerations worth pointing out. Most notably, -// we preprocess as much as possible (within reason) at the time of creation of a -// matcher. This includes: -// - creating a per-language map, which includes data for the raw base language -// and its canonicalized variant (if applicable), -// - expanding entries for the equivalence classes defined in CLDR's -// languageMatch data. -// The per-language map ensures that typically only a very small number of tags -// need to be considered. The pre-expansion of canonicalized subtags and -// equivalence classes reduces the amount of map lookups that need to be done at -// runtime. - -// matcher keeps a set of supported language tags, indexed by language. -type matcher struct { - default_ *haveTag - supported []*haveTag - index map[langID]*matchHeader - passSettings bool - preferSameScript bool -} - -// matchHeader has the lists of tags for exact matches and matches based on -// maximized and canonicalized tags for a given language. -type matchHeader struct { - haveTags []*haveTag - original bool -} - -// haveTag holds a supported Tag and its maximized script and region.

A -// translation of a format string is represented by a Message. -// -// -// Catalogs -// -// A Catalog defines a programmatic interface for setting message translations. -// It maintains a set of per-language dictionaries with translations for a set -// of keys. For message translation to function properly, a translation should -// be defined for each key for each supported language. A dictionary may be -// underspecified, though, if there is a parent language that already defines -// the key. For example, a Dictionary for "en-GB" could leave out entries that -// are identical to those in a dictionary for "en". -// -// -// Messages -// -// A Message is a format string which varies on the value of substitution -// variables. For instance, to indicate the number of results one could want "no -// results" if there are none, "1 result" if there is 1, and "%d results" for -// any other number. Catalog is agnostic to the kind of format strings that are -// used: for instance, messages can follow either the printf-style substitution -// from package fmt or use templates. -// -// A Message does not substitute arguments in the format string. This job is -// reserved for packages that render strings, such as message, that use Catalogs -// to selected string. This separation of concerns allows Catalog to be used to -// store any kind of formatting strings. -// -// -// Selecting messages based on linguistic features of substitution arguments -// -// Messages may vary based on any linguistic features of the argument values. -// The most common one is plural form, but others exist. -// -// Selection messages are provided in packages that provide support for a -// specific linguistic feature. The following snippet uses plural.Select: -// -// catalog.Set(language.English, "You are %d minute(s) late.", -// plural.Select(1, -// "one", "You are 1 minute late.", -// "other", "You are %d minutes late.")) -// -// In this example, a message is stored in the Catalog where one of two messages -// is selected based on the first argument, a number. The first message is -// selected if the argument is singular (identified by the selector "one") and -// the second message is selected in all other cases. The selectors are defined -// by the plural rules defined in CLDR. The selector "other" is special and will -// always match. Each language always defines one of the linguistic categories -// to be "other." For English, singular is "one" and plural is "other". -// -// Selects can be nested. This allows selecting sentences based on features of -// multiple arguments or multiple linguistic properties of a single argument. -// -// -// String interpolation -// -// There is often a lot of commonality between the possible variants of a -// message. For instance, in the example above the word "minute" varies based on -// the plural catogory of the argument, but the rest of the sentence is -// identical. Using interpolation the above message can be rewritten as: -// -// catalog.Set(language.English, "You are %d minute(s) late.", -// catalog.Var("minutes", -// plural.Select(1, "one", "minute", "other", "minutes")), -// catalog.String("You are %[1]d ${minutes} late.")) -// -// Var is defined to return the variable name if the message does not yield a -// match. This allows us to further simplify this snippet to -// -// catalog.Set(language.English, "You are %d minute(s) late.", -// catalog.Var("minutes", plural.Select(1, "one", "minute")), -// catalog.String("You are %d ${minutes} late.")) -// -// Overall this is still only a minor improvement, but things can get a lot more -// unwieldy if more than one linguistic feature is used to determine a message -// variant. Consider the following example: -// -// // argument 1: list of hosts, argument 2: list of guests -// catalog.Set(language.English, "%[1]v invite(s) %[2]v to their party.", -// catalog.Var("their", -// plural.Select(1, -// "one", gender.Select(1, "female", "her", "other", "his"))), -// catalog.Var("invites", plural.Select(1, "one", "invite")) -// catalog.String("%[1]v ${invites} %[2]v to ${their} party.")), -// -// Without variable substitution, this would have to be written as -// -// // argument 1: list of hosts, argument 2: list of guests -// catalog.Set(language.English, "%[1]v invite(s) %[2]v to their party.", -// plural.Select(1, -// "one", gender.Select(1, -// "female", "%[1]v invites %[2]v to her party." -// "other", "%[1]v invites %[2]v to his party."), -// "other", "%[1]v invites %[2]v to their party.") -// -// Not necessarily shorter, but using variables there is less duplication and -// the messages are more maintenance friendly. Moreover, languages may have up -// to six plural forms. This makes the use of variables more welcome. -// -// Different messages using the same inflections can reuse variables by moving -// them to macros. Using macros we can rewrite the message as: -// -// // argument 1: list of hosts, argument 2: list of guests -// catalog.SetString(language.English, "%[1]v invite(s) %[2]v to their party.", -// "%[1]v ${invites(1)} %[2]v to ${their(1)} party.") -// -// Where the following macros were defined separately. -// -// catalog.SetMacro(language.English, "invites", plural.Select(1, "one", "invite")) -// catalog.SetMacro(language.English, "their", plural.Select(1, -// "one", gender.Select(1, "female", "her", "other", "his"))), -// -// Placeholders use parentheses and the arguments to invoke a macro. -// -// -// Looking up messages -// -// Message lookup using Catalogs is typically only done by specialized packages -// and is not something the user should be concerned with.
