glog
====
Leveled execution logs for Go.
This is an efficient pure Go implementation of leveled logs in the
manner of the open source C++ package
http://code.google.com/p/google-glog
By binding methods to booleans it is possible to use the log package
without paying the expense of evaluating the arguments to the log.
Through the -vmodule flag, the package also provides fine-grained
control over logging at the file level.
The comment from glog.go introduces the ideas:
Package glog implements logging analogous to the Google-internal
C++ INFO/ERROR/V setup. It provides functions Info, Warning,
Error, Fatal, plus formatting variants such as Infof. It
also provides V-style logging controlled by the -v and
-vmodule=file=2 flags.
Basic examples:
glog.Info("Prepare to repel boarders")
glog.Fatalf("Initialization failed: %s", err)
See the documentation for the V function for an explanation
of these examples:
if glog.V(2) {
glog.Info("Starting transaction...")
}
glog.V(2).Infoln("Processed", nItems, "elements")
The repository contains an open source version of the log package
used inside Google. The master copy of the source lives inside
Google, not here. The code in this repo is for export only and is not itself
under development. Feature requests will be ignored.
Send bug reports to golang-nuts@googlegroups.com.

# HttpRouter [![Build Status](https://travis-ci.org/julienschmidt/httprouter.png?branch=master)](https://travis-ci.org/julienschmidt/httprouter) [![Coverage](http://gocover.io/_badge/github.com/julienschmidt/httprouter?0)](http://gocover.io/github.com/julienschmidt/httprouter) [![GoDoc](http://godoc.org/github.com/julienschmidt/httprouter?status.png)](http://godoc.org/github.com/julienschmidt/httprouter)
HttpRouter is a lightweight high performance HTTP request router
(also called *multiplexer* or just *mux* for short) for [Go](http://golang.org/).
In contrast to the [default mux](http://golang.org/pkg/net/http/#ServeMux) of Go's net/http package, this router supports
variables in the routing pattern and matches against the request method.
It also scales better.
The router is optimized for high performance and a small memory footprint.
It scales well even with very long paths and a large number of routes.
A compressing dynamic trie (radix tree) structure is used for efficient matching.
## Features
**Only explicit matches:** With other routers, like [http.ServeMux](http://golang.org/pkg/net/http/#ServeMux),
a requested URL path could match multiple patterns. Therefore they have some
awkward pattern priority rules, like *longest match* or *first registered,
first matched*. By design of this router, a request can only match exactly one
or no route. As a result, there are also no unintended matches, which makes it
great for SEO and improves the user experience.
**Stop caring about trailing slashes:** Choose the URL style you like, the
router automatically redirects the client if a trailing slash is missing or if
there is one extra. Of course it only does so, if the new path has a handler.
If you don't like it, you can [turn off this behavior](http://godoc.org/github.com/julienschmidt/httprouter#Router.RedirectTrailingSlash).
**Path auto-correction:** Besides detecting the missing or additional trailing
slash at no extra cost, the router can also fix wrong cases and remove
superfluous path elements (like `../` or `//`).
Is [CAPTAIN CAPS LOCK](http://www.urbandictionary.com/define.php?term=Captain+Caps+Lock) one of your users?
HttpRouter can help him by making a case-insensitive look-up and redirecting him
to the correct URL.
**Parameters in your routing pattern:** Stop parsing the requested URL path,
just give the path segment a name and the router delivers the dynamic value to
you. Because of the design of the router, path parameters are very cheap.
**Zero Garbage:** The matching and dispatching process generates zero bytes of
garbage. In fact, the only heap allocations that are made, is by building the
slice of the key-value pairs for path parameters. If the request path contains
no parameters, not a single heap allocation is necessary.
**Best Performance:** [Benchmarks speak for themselves](https://github.com/julienschmidt/go-http-routing-benchmark).
See below for technical details of the implementation.
**No more server crashes:** You can set a [Panic handler](http://godoc.org/github.com/julienschmidt/httprouter#Router.PanicHandler) to deal with panics
occurring during handling a HTTP request. The router then recovers and lets the
PanicHandler log what happened and deliver a nice error page.
Of course you can also set **custom [NotFound](http://godoc.org/github.com/julienschmidt/httprouter#Router.NotFound) and [MethodNotAllowed](http://godoc.org/github.com/julienschmidt/httprouter#Router.MethodNotAllowed) handlers** and [**serve static files**](http://godoc.org/github.com/julienschmidt/httprouter#Router.ServeFiles).
## Usage
This is just a quick introduction, view the [GoDoc](http://godoc.org/github.com/julienschmidt/httprouter) for details.
Let's start with a trivial example:
```go
package main
import (
"fmt"
"github.com/julienschmidt/httprouter"
"net/http"
"log"
)
func Index(w http.ResponseWriter, r *http.Request, _ httprouter.Params) {
fmt.Fprint(w, "Welcome!\n")
}
func Hello(w http.ResponseWriter, r *http.Request, ps httprouter.Params) {
fmt.Fprintf(w, "hello, %s!\n", ps.ByName("name"))
}
func main() {
router := httprouter.New()
router.GET("/", Index)
router.GET("/hello/:name", Hello)
log.Fatal(http.ListenAndServe(":8080", router))
}
```
### Named parameters
As you can see, `:name` is a *named parameter*.
The values are accessible via `httprouter.Params`, which is just a slice of `httprouter.Param`s.
You can get the value of a parameter either by its index in the slice, or by using the `ByName(name)` method:
`:name` can be retrived by `ByName("name")`.
Named parameters only match a single path segment:
```
Pattern: /user/:user
/user/gordon match
/user/you match
/user/gordon/profile no match
/user/ no match
```
**Note:** Since this router has only explicit matches, you can not register static routes and parameters for the same path segment. For example you can not register the patterns `/user/new` and `/user/:user` for the same request method at the same time. The routing of different request methods is independent from each other.
### Catch-All parameters
The second type are *catch-all* parameters and have the form `*name`.
Like the name suggests, they match everything.
Therefore they must always be at the **end** of the pattern:
```
Pattern: /src/*filepath
/src/ match
/src/somefile.go match
/src/subdir/somefile.go match
```
## How does it work?
The router relies on a tree structure which makes heavy use of *common prefixes*,
it is basically a *compact* [*prefix tree*](http://en.wikipedia.org/wiki/Trie)
(or just [*Radix tree*](http://en.wikipedia.org/wiki/Radix_tree)).
Nodes with a common prefix also share a common parent. Here is a short example
what the routing tree for the `GET` request method could look like:
```
Priority Path Handle
9 \ *<1>
3 ├s nil
2 |├earch\ *<2>
1 |└upport\ *<3>
2 ├blog\ *<4>
1 | └:post nil
1 | └\ *<5>
2 ├about-us\ *<6>
1 | └team\ *<7>
1 └contact\ *<8>
```
Every `*<num>` represents the memory address of a handler function (a pointer).
If you follow a path trough the tree from the root to the leaf, you get the
complete route path, e.g `\blog\:post\`, where `:post` is just a placeholder
([*parameter*](#named-parameters)) for an actual post name. Unlike hash-maps, a
tree structure also allows us to use dynamic parts like the `:post` parameter,
since we actually match against the routing patterns instead of just comparing
hashes. [As benchmarks show](https://github.com/julienschmidt/go-http-routing-benchmark),
this works very well and efficient.
Since URL paths have a hierarchical structure and make use only of a limited set
of characters (byte values), it is very likely that there are a lot of common
prefixes. This allows us to easily reduce the routing into ever smaller problems.
Moreover the router manages a separate tree for every request method.
For one thing it is more space efficient than holding a method->handle map in
every single node, for another thing is also allows us to greatly reduce the
routing problem before even starting the look-up in the prefix-tree.
For even better scalability, the child nodes on each tree level are ordered by
priority, where the priority is just the number of handles registered in sub
nodes (children, grandchildren, and so on..).
This helps in two ways:
1. Nodes which are part of the most routing paths are evaluated first. This
helps to make as much routes as possible to be reachable as fast as possible.
2. It is some sort of cost compensation. The longest reachable path (highest
cost) can always be evaluated first. The following scheme visualizes the tree
structure. Nodes are evaluated from top to bottom and from left to right.
```

```
## Why doesn't this work with http.Handler?
**It does!** The router itself implements the http.Handler interface.
Moreover the router provides convenient [adapters for http.Handler](http://godoc.org/github.com/julienschmidt/httprouter#Router.Handler)s and [http.HandlerFunc](http://godoc.org/github.com/julienschmidt/httprouter#Router.HandlerFunc)s
which allows them to be used as a [httprouter.Handle](http://godoc.org/github.com/julienschmidt/httprouter#Router.Handle) when registering a route.
The only disadvantage is, that no parameter values can be retrieved when a
http.Handler or http.HandlerFunc is used, since there is no efficient way to
pass the values with the existing function parameters.
Therefore [httprouter.Handle](http://godoc.org/github.com/julienschmidt/httprouter#Router.Handle) has a third function parameter.
Just try it out for yourself, the usage of HttpRouter is very straightforward. The package is compact and minimalistic, but also probably one of the easiest routers to set up.
## Where can I find Middleware *X*?
This package just provides a very efficient request router with a few extra
features. The router is just a [http.Handler](http://golang.org/pkg/net/http/#Handler),
you can chain any http.Handler compatible middleware before the router,
for example the [Gorilla handlers](http://www.gorillatoolkit.org/pkg/handlers).
Or you could [just write your own](http://justinas.org/writing-http-middleware-in-go/),
it's very easy!
Alternatively, you could try [a web framework based on HttpRouter](#web-frameworks-based-on-httprouter).
### Multi-domain / Sub-domains
Here is a quick example: Does your server serve multiple domains / hosts?
You want to use sub-domains?
Define a router per host!
```go
// We need an object that implements the http.Handler interface.
// Therefore we need a type for which we implement the ServeHTTP method.
// We just use a map here, in which we map host names (with port) to http.Handlers
type HostSwitch map[string]http.Handler
// Implement the ServerHTTP method on our new type
func (hs HostSwitch) ServeHTTP(w http.ResponseWriter, r *http.Request) {
// Check if a http.Handler is registered for the given host.
// If yes, use it to handle the request.
if handler := hs[r.Host]; handler != nil {
handler.ServeHTTP(w, r)
} else {
// Handle host names for wich no handler is registered
http.Error(w, "Forbidden", 403) // Or Redirect?
}
}
func main() {
// Initialize a router as usual
router := httprouter.New()
router.GET("/", Index)
router.GET("/hello/:name", Hello)
// Make a new HostSwitch and insert the router (our http handler)
// for example.com and port 12345
hs := make(HostSwitch)
hs["example.com:12345"] = router
// Use the HostSwitch to listen and serve on port 12345
log.Fatal(http.ListenAndServe(":12345", hs))
}
```
### Basic Authentication
Another quick example: Basic Authentification (RFC 2617) for handles:
```go
package main
import (
"bytes"
"encoding/base64"
"fmt"
"github.com/julienschmidt/httprouter"
"net/http"
"log"
"strings"
)
func BasicAuth(h httprouter.Handle, user, pass []byte) httprouter.Handle {
return func(w http.ResponseWriter, r *http.Request, ps httprouter.Params) {
const basicAuthPrefix string = "Basic "
// Get the Basic Authentication credentials
auth := r.Header.Get("Authorization")
if strings.HasPrefix(auth, basicAuthPrefix) {
// Check credentials
payload, err := base64.StdEncoding.DecodeString(auth[len(basicAuthPrefix):])
if err == nil {
pair := bytes.SplitN(payload, []byte(":"), 2)
if len(pair) == 2 &&
bytes.Equal(pair[0], user) &&
bytes.Equal(pair[1], pass) {
// Delegate request to the given handle
h(w, r, ps)
return
}
}
}
// Request Basic Authentication otherwise
w.Header().Set("WWW-Authenticate", "Basic realm=Restricted")
http.Error(w, http.StatusText(http.StatusUnauthorized), http.StatusUnauthorized)
}
}
func Index(w http.ResponseWriter, r *http.Request, _ httprouter.Params) {
fmt.Fprint(w, "Not protected!\n")
}
func Protected(w http.ResponseWriter, r *http.Request, _ httprouter.Params) {
fmt.Fprint(w, "Protected!\n")
}
func main() {
user := []byte("gordon")
pass := []byte("secret!")
router := httprouter.New()
router.GET("/", Index)
router.GET("/protected/", BasicAuth(Protected, user, pass))
log.Fatal(http.ListenAndServe(":8080", router))
}
```
## Chaining with the NotFound handler
**NOTE: It might be required to set [Router.HandleMethodNotAllowed](http://godoc.org/github.com/julienschmidt/httprouter#Router.HandleMethodNotAllowed) to `false` to avoid problems.**
You can use another [http.HandlerFunc](http://golang.org/pkg/net/http/#HandlerFunc), for example another router, to handle requests which could not be matched by this router by using the [Router.NotFound](http://godoc.org/github.com/julienschmidt/httprouter#Router.NotFound) handler. This allows chaining.
### Static files
The `NotFound` handler can for example be used to serve static files from the root path `/` (like an index.html file along with other assets):
```go
// Serve static files from the ./public directory
router.NotFound = http.FileServer(http.Dir("public")).ServeHTTP
```
But this approach sidesteps the strict core rules of this router to avoid routing problems. A cleaner approach is to use a distinct sub-path for serving files, like `/static/*filepath` or `/files/*filepath`.
## Web Frameworks based on HttpRouter
If the HttpRouter is a bit too minimalistic for you, you might try one of the following more high-level 3rd-party web frameworks building upon the HttpRouter package:
* [Ace](https://github.com/plimble/ace): Blazing fast Go Web Framework
* [api2go](https://github.com/univedo/api2go): A JSON API Implementation for Go
* [Gin](https://github.com/gin-gonic/gin): Features a martini-like API with much better performance
* [Goat](https://github.com/bahlo/goat): A minimalistic REST API server in Go
* [Hikaru](https://github.com/najeira/hikaru): Supports standalone and Google AppEngine
* [Hitch](https://github.com/nbio/hitch): Hitch ties httprouter, [httpcontext](https://github.com/nbio/httpcontext), and middleware up in a bow
* [kami](https://github.com/guregu/kami): A tiny web framework using x/net/context
* [Medeina](https://github.com/imdario/medeina): Inspired by Ruby's Roda and Cuba
* [Neko](https://github.com/rocwong/neko): A lightweight web application framework for Golang
* [Roxanna](https://github.com/iamthemuffinman/Roxanna): An amalgamation of httprouter, better logging, and hot reload
* [siesta](https://github.com/VividCortex/siesta): Composable HTTP handlers with contexts

// The router matches incoming requests by the request method and the path.
// If a handle is registered for this path and method, the router delegates the
// request to that function.
// For the methods GET, POST, PUT, PATCH and DELETE shortcut functions exist to
// register handles, for all other methods router.Handle can be used.
//
// The registered path, against which the router matches incoming requests, can
// contain two types of parameters:
// Syntax Type
// :name named parameter
// *name catch-all parameter
//
// Named parameters are dynamic path segments. They match anything until the
// next '/' or the path end:
// Path: /blog/:category/:post
//
// Requests:
// /blog/go/request-routers match: category="go", post="request-routers"
// /blog/go/request-routers/ no match, but the router would redirect
// /blog/go/ no match
// /blog/go/request-routers/comments no match
//
// Catch-all parameters match anything until the path end, including the
// directory index (the '/' before the catch-all). Since they match anything
// until the end, catch-all paramerters must always be the final path element.
// Path: /files/*filepath
//
// Requests:
// /files/ match: filepath="/"
// /files/LICENSE match: filepath="/LICENSE"
// /files/templates/article.html match: filepath="/templates/article.html"
// /files no match, but the router would redirect
//
// The value of parameters is saved as a slice of the Param struct, consisting
// each of a key and a value. The slice is passed to the Handle func as a third
// parameter.
// There are two ways to retrieve the value of a parameter:
// // by the name of the parameter
// user := ps.ByName("user") // defined by :user or *user
//
// // by the index of the parameter. This way you can also get the name (key)

# bufferpool [![Build Status](https://secure.travis-ci.org/pushrax/bufferpool.png)](http://travis-ci.org/pushrax/bufferpool)
The bufferpool package implements a thread-safe pool of reusable, equally sized `byte.Buffer`s.
If you're allocating `byte.Buffer`s very frequently, you can use this to speed up your
program and take strain off the garbage collector.

# faststats [![Build Status](https://api.travis-ci.org/pushrax/faststats.svg?branch=master)](https://travis-ci.org/pushrax/faststats)
faststats is a Go package for calculating various statistical measures in real time.
It is intended to be used in online networking applications, where significant overhead just for stats collection is undesirable.

# flatjson [![Build Status](https://api.travis-ci.org/pushrax/flatjson.svg?branch=master)](https://travis-ci.org/pushrax/flatjson)
flatjson is a Go package for collapsing structs into a flat map, which can then be JSON encoded.
The map values are pointers to the original struct fields, so it does not need to be regenerated when the values are updated.
Example use case:
```json
{
"Connections": {
"Open": 2,
"Accepted": 4
},
"ResponseTime": {
"P50": 0.045775,
"P90": 0.074299,
"P95": 0.096207
},
"Peers.IPv6": {
"Current": 0,
"Joined": 0,
"Left": 0,
"Reaped": 0,
"Completed": 0,
"Seeds": {
"Current": 0,
"Joined": 0,
"Left": 0,
"Reaped": 0
}
},
"Memory": {
"Alloc": 682208,
"TotalAlloc": 1032488,
"Sys": 5441784,
"Lookups": 28,
"Mallocs": 3326,
"Frees": 2567
}
}
```
is instead serialized as:
```json
{
"Connections.Accepted": 4,
"Connections.Open": 2,
"Memory.Alloc": 682208,
"Memory.Frees": 2567,
"Memory.Lookups": 281,
"Memory.Mallocs": 3326,

"Peers.IPv6.Left": 0,
"Peers.IPv6.Reaped": 0,
"Peers.IPv6.Seeds.Current": 0,
"Peers.IPv6.Seeds.Joined": 0,
"Peers.IPv6.Seeds.Left": 0,
"Peers.IPv6.Seeds.Reaped": 0,
"ResponseTime.P50": 0.045775,
"ResponseTime.P90": 0.074299,

========
Graceful is a Go 1.3+ package enabling graceful shutdown of http.Handler servers.
## Installation
To install, simply execute:
```
go get gopkg.in/tylerb/graceful.v1
```
I am using [gopkg.in](http://http://labix.org/gopkg.in) to control releases.
## Usage
Using Graceful is easy. Simply create your http.Handler and pass it to the `Run` function:
```go
package main
import (
"gopkg.in/tylerb/graceful.v1"
"net/http"
"fmt"
"time"
)
func main() {
mux := http.NewServeMux()
mux.HandleFunc("/", func(w http.ResponseWriter, req *http.Request) {
fmt.Fprintf(w, "Welcome to the home page!")
})
graceful.Run(":3001",10*time.Second,mux)
}
```
Another example, using [Negroni](https://github.com/codegangsta/negroni), functions in much the same manner:
```go
package main
import (
"github.com/codegangsta/negroni"
"gopkg.in/tylerb/graceful.v1"
"net/http"
"fmt"
"time"
)
func main() {
mux := http.NewServeMux()
mux.HandleFunc("/", func(w http.ResponseWriter, req *http.Request) {
fmt.Fprintf(w, "Welcome to the home page!")
})
n := negroni.Classic()
n.UseHandler(mux)
//n.Run(":3000")
graceful.Run(":3001",10*time.Second,n)
}
```
In addition to Run there are the http.Server counterparts ListenAndServe, ListenAndServeTLS and Serve, which allow you to configure HTTPS, custom timeouts and error handling.
Graceful may also be used by instantiating its Server type directly, which embeds an http.Server:
```go
mux := // ...
srv := &graceful.Server{
Timeout: 10 * time.Second,
Server: &http.Server{
Addr: ":1234",
Handler: mux,
},
}
srv.ListenAndServe()
```
This form allows you to set the ConnState callback, which works in the same way as in http.Server:
```go
mux := // ...
srv := &graceful.Server{
Timeout: 10 * time.Second,
ConnState: func(conn net.Conn, state http.ConnState) {
// conn has a new state
},
Server: &http.Server{
Addr: ":1234",
Handler: mux,
},
}
srv.ListenAndServe()
```
## Behaviour
When Graceful is sent a SIGINT or SIGTERM (possibly from ^C or a kill command), it:
1. Disables keepalive connections.
2. Closes the listening socket, allowing another process to listen on that port immediately.
3. Starts a timer of `timeout` duration to give active requests a chance to finish.
4. When timeout expires, closes all active connections.
5. Closes the `stopChan`, waking up any blocking goroutines.
6. Returns from the function, allowing the server to terminate.
## Notes
If the `timeout` argument to `Run` is 0, the server never times out, allowing all active requests to complete.
If you wish to stop the server in some way other than an OS signal, you may call the `Stop()` function.
This function stops the server, gracefully, using the new timeout value you provide. The `StopChan()` function
returns a channel on which you can block while waiting for the server to stop. This channel will be closed when
the server is stopped, allowing your execution to proceed. Multiple goroutines can block on this channel at the
same time and all will be signalled when stopping is complete.
## Contributing
If you would like to contribute, please:
1. Create a GitHub issue regarding the contribution. Features and bugs should be discussed beforehand.
2. Fork the repository.
3. Create a pull request with your solution. This pull request should reference and close the issues (Fix #2).
All pull requests should:
1. Pass [gometalinter -t .](https://github.com/alecthomas/gometalinter) with no warnings.
2. Be `go fmt` formatted.
