# libuv
libuv is a new platform layer for Node. Its purpose is to abstract IOCP on
Windows and epoll/kqueue/event ports/etc. on Unix systems. We intend to
eventually contain all platform differences in this library.
http://nodejs.org/
## Features
* Non-blocking TCP sockets
* Non-blocking named pipes
* UDP
* Timers
* Child process spawning
* Asynchronous DNS via `uv_getaddrinfo`.
* Asynchronous file system APIs `uv_fs_*`
* High resolution time `uv_hrtime`
* Current executable path look up `uv_exepath`
* Thread pool scheduling `uv_queue_work`
* ANSI escape code controlled TTY `uv_tty_t`
* File system events Currently supports inotify, `ReadDirectoryChangesW`
and kqueue. Event ports in the near future.
`uv_fs_event_t`
* IPC and socket sharing between processes `uv_write2`
## Community
* [Mailing list](http://groups.google.com/group/libuv)
## Documentation
* [include/uv.h](https://github.com/joyent/libuv/blob/master/include/uv.h)
&mdash; API documentation in the form of detailed header comments.
* [An Introduction to libuv](http://nikhilm.github.com/uvbook/) &mdash; An
overview of libuv with tutorials.
* [LXJS 2012 talk](http://www.youtube.com/watch?v=nGn60vDSxQ4) - High-level
introductory talk about libuv.
* [Tests and benchmarks](https://github.com/joyent/libuv/tree/master/test) -
API specification and usage examples.
## Build Instructions
For GCC (including MinGW) there are two methods building: via normal
makefiles or via GYP. GYP is a meta-build system which can generate MSVS,
Makefile, and XCode backends. It is best used for integration into other
projects. The old system is using plain GNU Makefiles.
To build via Makefile simply execute:
make
MinGW users should run this instead:
make PLATFORM=mingw
Out-of-tree builds are supported:
make builddir_name=/path/to/builddir
To build with Visual Studio run the vcbuild.bat file which will
checkout the GYP code into build/gyp and generate the uv.sln and
related files.
Windows users can also build from cmd-line using msbuild. This is
done by running vcbuild.bat from Visual Studio command prompt.
To have GYP generate build script for another system, make sure that
you have Python 2.6 or 2.7 installed, then checkout GYP into the
project tree manually:
mkdir -p build
svn co http://gyp.googlecode.com/svn/trunk build/gyp
Or:
mkdir -p build
git clone https://git.chromium.org/external/gyp.git build/gyp
Unix users run
./gyp_uv.py -f make
make -C out
Macintosh users run
./gyp_uv.py -f xcode
xcodebuild -project uv.xcodeproj -configuration Release -target All
Note for UNIX users: compile your project with `-D_LARGEFILE_SOURCE` and
`-D_FILE_OFFSET_BITS=64`. GYP builds take care of that automatically.
Note for Linux users: compile your project with `-D_GNU_SOURCE` when you
include `uv.h`. GYP builds take care of that automatically. If you use
autotools, add a `AC_GNU_SOURCE` declaration to your `configure.ac`.
## Supported Platforms
Microsoft Windows operating systems since Windows XP SP2. It can be built
with either Visual Studio or MinGW.
Linux 2.6 using the GCC toolchain.
MacOS using the GCC or XCode toolchain.
Solaris 121 and later using GCC toolchain.

# CONTRIBUTING
The libuv project welcomes new contributors. This document will guide you
through the process.
### FORK
Fork the project [on GitHub](https://github.com/joyent/libuv) and check out
your copy.
```
$ git clone https://github.com/username/libuv.git
$ cd libuv
$ git remote add upstream https://github.com/joyent/libuv.git
```
Now decide if you want your feature or bug fix to go into the master branch
or the stable branch. As a rule of thumb, bug fixes go into the stable branch
while new features go into the master branch.
The stable branch is effectively frozen; patches that change the libuv
API/ABI or affect the run-time behavior of applications get rejected.
In case of doubt, open an issue in the [issue tracker][], post your question
to the [libuv mailing list], or contact one of project maintainers
(@bnoordhuis, @piscisaureus, @indutny or @saghul) on [IRC][].
Especially do so if you plan to work on something big. Nothing is more
frustrating than seeing your hard work go to waste because your vision
does not align with that of a project maintainers.
### BRANCH
Okay, so you have decided on the proper branch. Create a feature branch
and start hacking:
```
$ git checkout -b my-feature-branch -t origin/v0.10
```
(Where v0.10 is the latest stable branch as of this writing.)
### CODE
Please adhere to libuv's code style. In general it follows the conventions from
the [Google C/C++ style guide]. Some of the key points, as well as some
additional guidelines, are enumerated below.
* Code that is specific to unix-y platforms should be placed in `src/unix`, and
declarations go into `src/uv-unix.h`.
* Source code that is Windows-specific goes into `src/win`, and related
publicly exported types, functions and macro declarations should generally
be declared in `include/uv-win.h`.
* Names should be descriptive and concise.
* All the symbols and types that libuv makes available publicly should be
prefixed with `uv_` (or `UV_` in case of macros).
* Internal, non-static functions should be prefixed with `uv__`.
* Use two spaces and no tabs.
* Lines should be wrapped at 80 characters.
* Ensure that lines have no trailing whitespace, and use unix-style (LF) line
endings.
* Use C89-compliant syntax. In other words, variables can only be declared at
the top of a scope (function, if/for/while-block).
* When writing comments, use properly constructed sentences, including
punctuation.
* When documenting APIs and/or source code, don't make assumptions or make
implications about race, gender, religion, political orientation or anything
else that isn't relevant to the project.
* Remember that source code usually gets written once and read often: ensure
the reader doesn't have to make guesses. Make sure that the purpose and inner
logic are either obvious to a reasonably skilled professional, or add a
comment that explains it.
### COMMIT
Make sure git knows your name and email address:
```
$ git config --global user.name "J. Random User"
$ git config --global user.email "j.random.user@example.com"
```
Writing good commit logs is important. A commit log should describe what
changed and why. Follow these guidelines when writing one:
1. The first line should be 50 characters or less and contain a short
description of the change prefixed with the name of the changed
subsystem (e.g. "net: add localAddress and localPort to Socket").
2. Keep the second line blank.
3. Wrap all other lines at 72 columns.
A good commit log looks like this:
```
subsystem: explaining the commit in one line
Body of commit message is a few lines of text, explaining things
in more detail, possibly giving some background about the issue
being fixed, etc etc.
The body of the commit message can be several paragraphs, and
please do proper word-wrap and keep columns shorter than about
72 characters or so. That way `git log` will show things
nicely even when it is indented.
```
The header line should be meaningful; it is what other people see when they
run `git shortlog` or `git log --oneline`.
Check the output of `git log --oneline files_that_you_changed` to find out
what subsystem (or subsystems) your changes touch.
### REBASE
Use `git rebase` (not `git merge`) to sync your work from time to time.
```
$ git fetch upstream
$ git rebase upstream/v0.10 # or upstream/master
```
### TEST
Bug fixes and features should come with tests. Add your tests in the
`test/` directory. Tests also need to be registered in `test/test-list.h`.
Look at other tests to see how they should be structured (license boilerplate,
the way entry points are declared, etc.).
Check README.md file to find out how to run the test suite and make sure that
there are no test regressions.
### PUSH
```
$ git push origin my-feature-branch
```
Go to https://github.com/username/libuv and select your feature branch. Click
the 'Pull Request' button and fill out the form.
Pull requests are usually reviewed within a few days. If there are comments
to address, apply your changes in a separate commit and push that to your
feature branch. Post a comment in the pull request afterwards; GitHub does
not send out notifications when you add commits.

![libuv][libuv_banner]
## Overview
libuv is a multi-platform support library with a focus on asynchronous I/O. It
was primarily developed for use by [Node.js](http://nodejs.org), but it's also
used by Mozilla's [Rust language](http://www.rust-lang.org/),
[Luvit](http://luvit.io/), [Julia](http://julialang.org/),
[pyuv](https://github.com/saghul/pyuv), and [others](https://github.com/joyent/libuv/wiki/Projects-that-use-libuv).
## Feature highlights
* Full-featured event loop backed by epoll, kqueue, IOCP, event ports.
* Asynchronous TCP and UDP sockets
* Asynchronous DNS resolution
* Asynchronous file and file system operations
* File system events
* ANSI escape code controlled TTY
* IPC with socket sharing, using Unix domain sockets or named pipes (Windows)
* Child processes
* Thread pool
* Signal handling
* High resolution clock
* Threading and synchronization primitives
## Community
* [Mailing list](http://groups.google.com/group/libuv)
## Documentation
* [include/uv.h](https://github.com/joyent/libuv/blob/master/include/uv.h)
&mdash; API documentation in the form of detailed header comments.
* [An Introduction to libuv](http://nikhilm.github.com/uvbook/)
&mdash; An overview of libuv with tutorials.
* [LXJS 2012 talk](http://www.youtube.com/watch?v=nGn60vDSxQ4)
&mdash; High-level introductory talk about libuv.
* [Tests and benchmarks](https://github.com/joyent/libuv/tree/master/test)
&mdash; API specification and usage examples.
* [libuv-dox](https://github.com/thlorenz/libuv-dox)
&mdash; Documenting types and methods of libuv, mostly by reading uv.h.
## Build Instructions
For GCC there are two methods building: via autotools or via [GYP][].
GYP is a meta-build system which can generate MSVS, Makefile, and XCode
backends. It is best used for integration into other projects.
To build with autotools:
$ sh autogen.sh
$ ./configure
$ make
$ make check
$ make install
### Windows
First, [Python][] 2.6 or 2.7 must be installed as it is required by [GYP][].
If python is not in your path set the environment variable `PYTHON` to its
location. For example: `set PYTHON=C:\Python27\python.exe`
To build with Visual Studio, launch a git shell (e.g. Cmd or PowerShell)
and run vcbuild.bat which will checkout the GYP code into build/gyp and
generate uv.sln as well as related project files.
To have GYP generate build script for another system, checkout GYP into the
project tree manually:
$ mkdir -p build
$ git clone https://git.chromium.org/external/gyp.git build/gyp
### Unix
Run:
$ ./gyp_uv.py -f make
$ make -C out
### OS X
Run:
$ ./gyp_uv.py -f xcode
$ xcodebuild -ARCHS="x86_64" -project uv.xcodeproj \
-configuration Release -target All
Note to OS X users:
Make sure that you specify the architecture you wish to build for in the
"ARCHS" flag. You can specify more than one by delimiting with a space
(e.g. "x86_64 i386").
### Android
Run:
$ source ./android-configure NDK_PATH gyp
$ make -C out
Note for UNIX users: compile your project with `-D_LARGEFILE_SOURCE` and
`-D_FILE_OFFSET_BITS=64`. GYP builds take care of that automatically.
### Running tests
Run:
$ ./gyp_uv.py -f make
$ make -C out
$ ./out/Debug/run-tests
## Supported Platforms
Microsoft Windows operating systems since Windows XP SP2. It can be built
with either Visual Studio or MinGW. Consider using
[Visual Studio Express 2010][] or later if you do not have a full Visual
Studio license.
Linux using the GCC toolchain.
OS X using the GCC or XCode toolchain.
Solaris 121 and later using GCC toolchain.
## Patches

/* A connection is modeled as an abstraction on top of two simple state
* machines, one for reading and one for writing. Either state machine
* is, when active, in one of three states: busy, done or stop; the fourth
* and final state, dead, is an end state and only relevant when shutting
* down the connection. A short overview:
*
* busy done stop
* ----------|---------------------------|--------------------|------|
* readable | waiting for incoming data | have incoming data | idle |
* writable | busy writing out data | completed write | idle |
*
* We could remove the done state from the writable state machine. For our
* purposes, it's functionally equivalent to the stop state.
*
* When the connection with upstream has been established, the client_ctx
* moves into a state where incoming data from the client is sent upstream
* and vice versa, incoming data from upstream is sent to the client. In
* other words, we're just piping data back and forth. See conn_cycle()
* for details.
*
* An interesting deviation from libuv's I/O model is that reads are discrete
* rather than continuous events. In layman's terms, when a read operation
* completes, the connection stops reading until further notice.
*
* The rationale for this approach is that we have to wait until the data
* has been sent out again before we can reuse the read buffer.
*
* It also pleasingly unifies with the request model that libuv uses for
* writes and everything else; libuv may switch to a request model for
* reads in the future.
