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/v1.x +``` + +(Where v1.x 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 `include/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/v1.x # 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. + + +[issue tracker]: https://github.com/libuv/libuv/issues +[libuv mailing list]:

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: + + $ git clone https://chromium.googlesource.com/external/gyp.git build/gyp + +### Unix + +Run: + + $ ./gyp_uv.py -f make + $ make -C out + +Run `./gyp_uv.py -f make -Dtarget_arch=x32` to build [x32][] binaries. + +### OS X + +Run: + + $ ./gyp_uv.py -f xcode + $ xcodebuild -ARCHS="x86_64" -project uv.xcodeproj \ + -configuration Release -target All + +Using Homebrew: + + $ brew install --HEAD libuv + +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. + +### Using Ninja + +To use ninja for build on ninja supported platforms, run: + + $ ./gyp_uv.py -f ninja + $ ninja -C out/Debug #for debug build OR + $ ninja -C out/Release + + +### 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. + +AIX 6 and later using GCC toolchain (see notes). + +### AIX Notes + +AIX support for filesystem events requires the non-default IBM `bos.ahafs` +package to be installed.

It's designed +around the event-driven asynchronous I/O model. + +The library provides much more than simply abstraction over different I/O polling mechanisms: +'handles' and 'streams' provide a high level abstraction for sockets and other entities; +cross-platform file I/O and threading functionality is also provided, amongst other things. + +Here is a diagram illustrating the different parts that compose libuv and what subsystem they +relate to: + +.. image:: static/architecture.png + :scale: 75% + :align: center + + +Handles and requests +^^^^^^^^^^^^^^^^^^^^ + +libuv provides users with 2 abstractions to work with, in combination with the event loop: +handles and requests. + +Handles represent long-lived objects capable of performing certain operations while active. Some +examples: a prepare handle gets its callback called once every loop iteration when active, and +a TCP server handle get its connection callback called every time there is a new connection. + +Requests represent (typically) short-lived operations. These operations can be performed over a +handle: write requests are used to write data on a handle; or standalone: getaddrinfo requests +don't need a handle they run directly on the loop. + + +The I/O loop +^^^^^^^^^^^^ + +The I/O (or event) loop is the central part of libuv. It establishes the content for all I/O +operations, and it's meant to be tied to a single thread. One can run multiple event loops +as long as each runs in a different thread. The libuv event loop (or any other API involving +the loop or handles, for that matter) **is not thread-safe** except where stated otherwise. + +The event loop follows the rather usual single threaded asynchronous I/O approach: all (network) +I/O is performed on non-blocking sockets which are polled using the best mechanism available +on the given platform: epoll on Linux, kqueue on OSX and other BSDs, event ports on SunOS and IOCP +on Windows. As part of a loop iteration the loop will block waiting for I/O activity on sockets +which have been added to the poller and callbacks will be fired indicating socket conditions +(readable, writable hangup) so handles can read, write or perform the desired I/O operation. + +In order to better understand how the event loop operates, the following diagram illustrates all +stages of a loop iteration: + +.. image:: static/loop_iteration.png + :scale: 75% + :align: center + + +#. The loop concept of 'now' is updated. The event loop caches the current time at the start of + the event loop tick in order to reduce the number of time-related system calls. + +#. If the loop is *alive* an iteration is started, otherwise the loop will exit immediately. So, + when is a loop considered to be *alive*? If a loop has active and ref'd handles, active + requests or closing handles it's considered to be *alive*. + +#. Due timers are run. All active timers scheduled for a time before the loop's concept of *now* + get their callbacks called. + +#. Pending callbacks are called. All I/O callbacks are called right after polling for I/O, for the + most part. There are cases, however, in which calling such a callback is deferred for the next + loop iteration. If the previous iteration deferred any I/O callback it will be run at this point. + +#. Idle handle callbacks are called. Despite the unfortunate name, idle handles are run on every + loop iteration, if they are active. + +#. Prepare handle callbacks are called. Prepare handles get their callbacks called right before + the loop will block for I/O. + +#. Poll timeout is calculated. Before blocking for I/O the loop calculates for how long it should + block. These are the rules when calculating the timeout: + + * If the loop was run with the ``UV_RUN_NOWAIT`` flag, the timeout is 0. + * If the loop is going to be stopped (:c:func:`uv_stop` was called), the timeout is 0. + * If there are no active handles or requests, the timeout is 0. + * If there are any idle handles active, the timeout is 0. + * If there are any handles pending to be closed, the timeout is 0. + * If none of the above cases was matched, the timeout of the closest timer is taken, or + if there are no active timers, infinity. + +#. The loop blocks for I/O. At this point the loop will block for I/O for the timeout calculated + on the previous step. All I/O related handles that were monitoring a given file descriptor + for a read or write operation get their callbacks called at this point. + +#. Check handle callbacks are called. Check handles get their callbacks called right after the + loop has blocked for I/O. Check handles are essentially the counterpart of prepare handles. + +#. Close callbacks are called. If a handle was closed by calling :c:func:`uv_close` it will + get the close callback called. + +#. Special case in case the loop was run with ``UV_RUN_ONCE``, as it implies forward progress. + It's possible that no I/O callbacks were fired after blocking for I/O, but some time has passed + so there might be timers which are due, those timers get their callbacks called. + +#. Iteration ends. If the loop was run with ``UV_RUN_NOWAIT`` or ``UV_RUN_ONCE`` modes the + iteration is ended and :c:func:`uv_run` will return. If the loop was run with ``UV_RUN_DEFAULT`` + it will continue from the start if it's still *alive*, otherwise it will also end. + + +.. important:: + libuv uses a thread pool to make asynchronous file I/O operations possible, but + network I/O is **always** performed in a single thread, each loop's thread. + +.. note:: + While the polling mechanism is different, libuv makes the execution model consistent + across Unix systems and Windows. + + +File I/O +^^^^^^^^ + +Unlike network I/O, there are no platform-specific file I/O primitives libuv could rely on, +so the current approach is to run blocking file I/O operations in a thread pool. + +For a thorough explanation of the cross-platform file I/O landscape, checkout +`this post `_. + +libuv currently uses a global thread pool on which all loops can queue work on. 3 types of +operations are currently run on this pool: + + * Filesystem operations + * DNS functions (getaddrinfo and getnameinfo) + * User specified code via :c:func:`uv_queue_work` + +.. warning:: + See the :c:ref:`threadpool` section for more details, but keep in mind the thread pool size + is quite limited. diff --git a/outside/libuv-v1.7.5/docs/src/dll.rst b/outside/libuv-v1.7.5/docs/src/dll.rst new file mode 100644 index 0000000000..fb13f90815 --- /dev/null +++ b/outside/libuv-v1.7.5/docs/src/dll.rst @@ -0,0 +1,44 @@ + +.. _dll: + +Shared library handling +======================= + +libuv provides cross platform utilities for loading shared libraries and +retrieving symbols from them, using the following API. + + +Data types +---------- + +.. c:type:: uv_lib_t + + Shared library data type. + + +Public members +^^^^^^^^^^^^^^ + +N/A + + +API +--- + +.. c:function:: int uv_dlopen(const char* filename, uv_lib_t* lib) + + Opens a shared library.

This is done repeatedly until all idle watchers are inactive. + * - If a watcher starts another watcher of the same type its callback is not + * immediately queued. For check and prepare watchers, that means that if + * a watcher makes another of the same type active, it'll not be called until + * the next event loop iteration. For idle. watchers this means that the + * newly activated idle watcher might not be queued immediately. + * - Prepare, check, idle watchers keep the event loop alive even when they're + * not active. + * + * This is what the test globally does: + * + * - prepare_1 is always active and counts event loop iterations. It also + * creates and starts prepare_2 every other iteration. Finally it verifies + * that no idle watchers are active before polling. + * - prepare_2 is started by prepare_1 every other iteration. It immediately + * stops itself. It verifies that a watcher is not queued immediately + * if created by another watcher of the same type. + * - There's a check watcher that stops the event loop after a certain number + * of iterations. It starts a varying number of idle_1 watchers. + * - Idle_1 watchers stop themselves after being called a few times. All idle_1 + * watchers try to start the idle_2 watcher if it is not already started or + * awaiting its close callback. + * - The idle_2 watcher always exists but immediately closes itself after + * being started by a check_1 watcher.
