You can set a custom timeout duration via the `SetWriteTimeout` method. + +The default mode is to pass write errors from the socket to the caller. This includes write errors the library will +automatically recover from (DogStatsD server not ready yet or is restarting). You can drop these errors and emulate +the UDP behaviour by setting the `SkipErrors` property to `true`. Please note that packets will be dropped in both modes. + +## Development + +Run the tests with: + + $ go test + +## Documentation + +Please see: http://godoc.org/github.com/DataDog/datadog-go/statsd + +## License + +go-dogstatsd is released under the [MIT license](http://www.opensource.org/licenses/mit-license.php). + +## Credits + +Original code by [ooyala](https://github.com/ooyala/go-dogstatsd). diff --git a/vendor/github.com/DataDog/datadog-go/statsd/statsd.go b/vendor/github.com/DataDog/datadog-go/statsd/statsd.go new file mode 100644 index 0000000..0ae4dac --- /dev/null +++ b/vendor/github.com/DataDog/datadog-go/statsd/statsd.go @@ -0,0 +1,680 @@ +// Copyright 2013 Ooyala, Inc. + +/* +Package statsd provides a Go dogstatsd client.

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

One poster was interested in being +able to log an HTTP request context id in every log line in the same goroutine +as the incoming HTTP request, without having to change every library and +function call he was interested in logging. + +This would be pretty useful. Provided that you could get some kind of +goroutine-local-storage, you could call +[log.SetOutput](http://golang.org/pkg/log/#SetOutput) with your own logging +writer that checks goroutine-local-storage for some context information and +adds that context to your log lines. + +But alas, Andrew Gerrand's typically diplomatic answer to the question of +goroutine-local variables was: + +> We wouldn't even be having this discussion if thread local storage wasn't +> useful. But every feature comes at a cost, and in my opinion the cost of +> threadlocals far outweighs their benefits. They're just not a good fit for +> Go. + +So, yeah, that makes sense. That's a pretty good reason for why the language +won't support a specific and (relatively) unuseful feature that requires some +runtime changes, just for the sake of a little bit of log improvement. + +But does Go require runtime changes? + +### How it works ### + +Go has pretty fantastic introspective and reflective features, but one thing Go +doesn't give you is any kind of access to the stack pointer, or frame pointer, +or goroutine id, or anything contextual about your current stack. It gives you +access to your list of callers, but only along with program counters, which are +fixed at compile time. + +But it does give you the stack. + +So, we define 16 special functions and embed base-16 tags into the stack using +the call order of those 16 functions. Then, we can read our tags back out of +the stack looking at the callers list. + +We then use these tags as an index into a traditional map for implementing +this library. + +### What are people saying? ### + +"Wow, that's horrifying." + +"This is the most terrible thing I have seen in a very long time." + +"Where is it getting a context from? Is this serializing all the requests? +What the heck is the client being bound to? What are these tags? Why does he +need callers? Oh god no. No no no." + +### Docs ### + +Please see the docs at http://godoc.org/github.com/jtolds/gls + +### Related ### + +If you're okay relying on the string format of the current runtime stacktrace +including a unique goroutine id (not guaranteed by the spec or anything, but +very unlikely to change within a Go release), you might be able to squeeze +out a bit more performance by using this similar library, inspired by some +code Brad Fitzpatrick wrote for debugging his HTTP/2 library: +https://github.com/tylerb/gls (in contrast, jtolds/gls doesn't require +any knowledge of the string format of the runtime stacktrace, which +probably adds unnecessary overhead). diff --git a/vendor/github.com/jtolds/gls/context.go b/vendor/github.com/jtolds/gls/context.go new file mode 100644 index 0000000..618a171 --- /dev/null +++ b/vendor/github.com/jtolds/gls/context.go @@ -0,0 +1,153 @@ +// Package gls implements goroutine-local storage. +package gls + +import ( + "sync" +) + +var ( + mgrRegistry = make(map[*ContextManager]bool) + mgrRegistryMtx sync.RWMutex +) + +// Values is simply a map of key types to value types.

The package is used by the +[ogletest][ogletest] testing framework and [oglemock][oglemock] mocking +framework, which may be more directly useful to you, but can be generically used +elsewhere as well. + +A "matcher" is simply an object with a `Matches` method defining a set of golang +values matched by the matcher, and a `Description` method describing that set. +For example, here are some matchers: + +```go +// Numbers +Equals(17.13) +LessThan(19) + +// Strings +Equals("taco") +HasSubstr("burrito") +MatchesRegex("t.*o") + +// Combining matchers +AnyOf(LessThan(17), GreaterThan(19)) +``` + +There are lots more; see [here][reference] for a reference.
