This document will guide you through the process. ### FORK Fork the project [on GitHub](https://github.com/libuv/libuv) and check out your copy. ``` $ git clone https://github.com/username/libuv.git $ cd libuv $ git remote add upstream https://github.com/libuv/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/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.

Export your public key: $ gpg --armor --export saghul@gmail.com > saghul.asc Store it as a blob on the repo: $ git hash-object -w saghul.asc The previous command returns a hash, copy it. For the sake of this explanation, we'll assume it's 'abcd1234'. Storing the blob in git is not enough, it could be garbage collected since nothing references it, so we'll create a tag for it: $ git tag -s pubkey-saghul abcd1234 Commit the changes and push: $ git push origin pubkey-saghul libuv-v1.8.0/Makefile.am000066400000000000000000000322271263361716600151040ustar00rootroot00000000000000# Copyright (c) 2013, Ben Noordhuis # # Permission to use, copy, modify, and/or distribute this software for any # purpose with or without fee is hereby granted, provided that the above # copyright notice and this permission notice appear in all copies. # # THE SOFTWARE IS PROVIDED "AS IS" AND THE AUTHOR DISCLAIMS ALL WARRANTIES # WITH REGARD TO THIS SOFTWARE INCLUDING ALL IMPLIED WARRANTIES OF # MERCHANTABILITY AND FITNESS.

It was primarily developed for use by [Node.js](http://nodejs.org), but it's also used by [Luvit](http://luvit.io/), [Julia](http://julialang.org/), [pyuv](https://github.com/saghul/pyuv), and [others](https://github.com/libuv/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 ## Versioning Starting with version 1.0.0 libuv follows the [semantic versioning](http://semver.org/) scheme. The API change and backwards compatibility rules are those indicated by SemVer. libuv will keep a stable ABI across major releases. ## Community * [Mailing list](http://groups.google.com/group/libuv) * [IRC chatroom (#libuv@irc.freenode.org)](http://webchat.freenode.net?channels=libuv&uio=d4) ## Documentation ### Official API documentation Located in the docs/ subdirectory. It uses the [Sphinx](http://sphinx-doc.org/) framework, which makes it possible to build the documentation in multiple formats. Show different supported building options: $ make help Build documentation as HTML: $ make html Build documentation as man pages: $ make man Build documentation as ePub: $ make epub NOTE: Windows users need to use make.bat instead of plain 'make'. Documentation can be browsed online [here](http://docs.libuv.org). The [tests and benchmarks](https://github.com/libuv/libuv/tree/master/test) also serve as API specification and usage examples. ### Other resources * [An Introduction to libuv](http://nikhilm.github.com/uvbook/) — An overview of libuv with tutorials. * [LXJS 2012 talk](http://www.youtube.com/watch?v=nGn60vDSxQ4) — High-level introductory talk about libuv. * [libuv-dox](https://github.com/thlorenz/libuv-dox) — Documenting types and methods of libuv, mostly by reading uv.h. * [learnuv](https://github.com/thlorenz/learnuv) — Learn uv for fun and profit, a self guided workshop to libuv. These resources are not handled by libuv maintainers and might be out of date. Please verify it before opening new issues. ## Downloading libuv can be downloaded either from the [GitHub repository](https://github.com/libuv/libuv) or from the [downloads site](http://dist.libuv.org/dist/). Starting with libuv 1.7.0, binaries for Windows are also provided. This is to be considered EXPERIMENTAL. Before verifying the git tags or signature files, importing the relevant keys is necessary. Key IDs are listed in the [MAINTAINERS](https://github.com/libuv/libuv/blob/master/MAINTAINERS.md) file, but are also available as git blob objects for easier use. Importing a key the usual way: $ gpg --keyserver pool.sks-keyservers.net \ --recv-keys AE9BC059 Importing a key from a git blob object: $ git show pubkey-saghul | gpg --import ### Verifying releases Git tags are signed with the developer's key, they can be verified as follows: $ git verify-tag v1.6.1 Starting with libuv 1.7.0, the tarballs stored in the [downloads site](http://dist.libuv.org/dist/) are signed and an accompanying signature file sit alongside each. Once both the release tarball and the signature file are downloaded, the file can be verified as follows: $ gpg --verify libuv-1.7.0.tar.gz.sign ## Build Instructions For GCC there are two build methods: 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: $ 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. This package provides the AIX Event Infrastructure that is detected by `autoconf`. [IBM documentation](http://www.ibm.com/developerworks/aix/library/au-aix_event_infrastructure/) describes the package in more detail. AIX support for filesystem events is not compiled when building with `gyp`. ## Patches See the [guidelines for contributing][].

A NULL callback is allowed. .. note:: Unlike other handle initialization functions, it immediately starts the handle. .. c:function:: int uv_async_send(uv_async_t* async) Wakeup the event loop and call the async handle's callback. .. note:: It's safe to call this function from any thread. The callback will be called on the loop thread. .. warning:: libuv will coalesce calls to :c:func:`uv_async_send`, that is, not every call to it will yield an execution of the callback.

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. libuv-v1.8.0/docs/src/dll.rst000066400000000000000000000017031263361716600160670ustar00rootroot00000000000000 .. _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. The filename is in utf-8. Returns 0 on success and -1 on error. Call :c:func:`uv_dlerror` to get the error message. .. c:function:: void uv_dlclose(uv_lib_t* lib) Close the shared library. .. c:function:: int uv_dlsym(uv_lib_t* lib, const char* name, void** ptr) Retrieves a data pointer from a dynamic library. It is legal for a symbol to map to NULL. Returns 0 on success and -1 if the symbol was not found. .. c:function:: const char* uv_dlerror(const uv_lib_t* lib) Returns the last uv_dlopen() or uv_dlsym() error message. libuv-v1.8.0/docs/src/dns.rst000066400000000000000000000067661263361716600161160ustar00rootroot00000000000000 .. _dns: DNS utility functions ===================== libuv provides asynchronous variants of `getaddrinfo` and `getnameinfo`. Data types ---------- .. c:type:: uv_getaddrinfo_t `getaddrinfo` request type. .. c:type:: void (*uv_getaddrinfo_cb)(uv_getaddrinfo_t* req, int status, struct addrinfo* res) Callback which will be called with the getaddrinfo request result once complete.

API --- .. c:function:: int uv_getaddrinfo(uv_loop_t* loop, uv_getaddrinfo_t* req, uv_getaddrinfo_cb getaddrinfo_cb, const char* node, const char* service, const struct addrinfo* hints) Asynchronous :man:`getaddrinfo(3)`. Either node or service may be NULL but not both. `hints` is a pointer to a struct addrinfo with additional address type constraints, or NULL. Consult `man -s 3 getaddrinfo` for more details. Returns 0 on success or an error code < 0 on failure. If successful, the callback will get called sometime in the future with the lookup result, which is either: * status == 0, the res argument points to a valid `struct addrinfo`, or * status < 0, the res argument is NULL. See the UV_EAI_* constants. Call :c:func:`uv_freeaddrinfo` to free the addrinfo structure. .. versionchanged:: 1.3.0 the callback parameter is now allowed to be NULL, in which case the request will run **synchronously**. .. c:function:: void uv_freeaddrinfo(struct addrinfo* ai) Free the struct addrinfo. Passing NULL is allowed and is a no-op. .. c:function:: int uv_getnameinfo(uv_loop_t* loop, uv_getnameinfo_t* req, uv_getnameinfo_cb getnameinfo_cb, const struct sockaddr* addr, int flags) Asynchronous :man:`getnameinfo(3)`. Returns 0 on success or an error code < 0 on failure. If successful, the callback will get called sometime in the future with the lookup result. Consult `man -s 3 getnameinfo` for more details. .. versionchanged:: 1.3.0 the callback parameter is now allowed to be NULL, in which case the request will run **synchronously**. .. seealso:: The :c:type:`uv_req_t` API functions also apply. libuv-v1.8.0/docs/src/errors.rst000066400000000000000000000113701263361716600166310ustar00rootroot00000000000000 .. _errors: Error handling ============== In libuv errors are negative numbered constants. As a rule of thumb, whenever there is a status parameter, or an API functions returns an integer, a negative number will imply an error. .. note:: Implementation detail: on Unix error codes are the negated `errno` (or `-errno`), while on Windows they are defined by libuv to arbitrary negative numbers.

Data types ---------- .. c:type:: uv_fs_event_t FS Event handle type. .. c:type:: void (*uv_fs_event_cb)(uv_fs_event_t* handle, const char* filename, int events, int status) Callback passed to :c:func:`uv_fs_event_start` which will be called repeatedly after the handle is started. If the handle was started with a directory the `filename` parameter will be a relative path to a file contained in the directory. The `events` parameter is an ORed mask of :c:type:`uv_fs_event` elements. .. c:type:: uv_fs_event Event types that :c:type:`uv_fs_event_t` handles monitor. :: enum uv_fs_event { UV_RENAME = 1, UV_CHANGE = 2 }; .. c:type:: uv_fs_event_flags Flags that can be passed to :c:func:`uv_fs_event_start` to control its behavior. :: enum uv_fs_event_flags { /* * By default, if the fs event watcher is given a directory name, we will * watch for all events in that directory.

API --- .. c:function:: int uv_fs_event_init(uv_loop_t* loop, uv_fs_event_t* handle) Initialize the handle. .. c:function:: int uv_fs_event_start(uv_fs_event_t* handle, uv_fs_event_cb cb, const char* path, unsigned int flags) Start the handle with the given callback, which will watch the specified `path` for changes. `flags` can be an ORed mask of :c:type:`uv_fs_event_flags`. .. note:: Currently the only supported flag is ``UV_FS_EVENT_RECURSIVE`` and only on OSX and Windows. .. c:function:: int uv_fs_event_stop(uv_fs_event_t* handle) Stop the handle, the callback will no longer be called. .. c:function:: int uv_fs_event_getpath(uv_fs_event_t* handle, char* buffer, size_t* size) Get the path being monitored by the handle. The buffer must be preallocated by the user. Returns 0 on success or an error code < 0 in case of failure. On success, `buffer` will contain the path and `size` its length. If the buffer is not big enough UV_ENOBUFS will be returned and len will be set to the required size. .. versionchanged:: 1.3.0 the returned length no longer includes the terminating null byte, and the buffer is not null terminated. .. seealso:: The :c:type:`uv_handle_t` API functions also apply. libuv-v1.8.0/docs/src/fs_poll.rst000066400000000000000000000046071263361716600167600ustar00rootroot00000000000000 .. _fs_poll: :c:type:`uv_fs_poll_t` --- FS Poll handle ========================================= FS Poll handles allow the user to monitor a given path for changes. Unlike :c:type:`uv_fs_event_t`, fs poll handles use `stat` to detect when a file has changed so they can work on file systems where fs event handles can't. Data types ---------- .. c:type:: uv_fs_poll_t FS Poll handle type. .. c:type:: void (*uv_fs_poll_cb)(uv_fs_poll_t* handle, int status, const uv_stat_t* prev, const uv_stat_t* curr) Callback passed to :c:func:`uv_fs_poll_start` which will be called repeatedly after the handle is started, when any change happens to the monitored path. The callback is invoked with `status < 0` if `path` does not exist or is inaccessible. The watcher is *not* stopped but your callback is not called again until something changes (e.g. when the file is created or the error reason changes). When `status == 0`, the callback receives pointers to the old and new :c:type:`uv_stat_t` structs. They are valid for the duration of the callback only. Public members ^^^^^^^^^^^^^^ N/A .. seealso:: The :c:type:`uv_handle_t` members also apply. API --- .. c:function:: int uv_fs_poll_init(uv_loop_t* loop, uv_fs_poll_t* handle) Initialize the handle. .. c:function:: int uv_fs_poll_start(uv_fs_poll_t* handle, uv_fs_poll_cb poll_cb, const char* path, unsigned int interval) Check the file at `path` for changes every `interval` milliseconds. .. note:: For maximum portability, use multi-second intervals. Sub-second intervals will not detect all changes on many file systems. .. c:function:: int uv_fs_poll_stop(uv_fs_poll_t* handle) Stop the handle, the callback will no longer be called. .. c:function:: int uv_fs_poll_getpath(uv_fs_poll_t* handle, char* buffer, size_t* size) Get the path being monitored by the handle. The buffer must be preallocated by the user. Returns 0 on success or an error code < 0 in case of failure. On success, `buffer` will contain the path and `size` its length. If the buffer is not big enough UV_ENOBUFS will be returned and len will be set to the required size. .. versionchanged:: 1.3.0 the returned length no longer includes the terminating null byte, and the buffer is not null terminated. .. seealso:: The :c:type:`uv_handle_t` API functions also apply. libuv-v1.8.0/docs/src/handle.rst000066400000000000000000000143301263361716600165470ustar00rootroot00000000000000 .. _handle: :c:type:`uv_handle_t` --- Base handle ===================================== `uv_handle_t` is the base type for all libuv handle types. Structures are aligned so that any libuv handle can be cast to `uv_handle_t`. All API functions defined here work with any handle type. Data types ---------- .. c:type:: uv_handle_t The base libuv handle type. .. c:type:: uv_any_handle Union of all handle types. .. c:type:: void (*uv_alloc_cb)(uv_handle_t* handle, size_t suggested_size, uv_buf_t* buf) Type definition for callback passed to :c:func:`uv_read_start` and :c:func:`uv_udp_recv_start`. The user must fill the supplied :c:type:`uv_buf_t` structure with whatever size, as long as it's > 0. A suggested size (65536 at the moment) is provided, but it doesn't need to be honored. Setting the buffer's length to 0 will trigger a ``UV_ENOBUFS`` error in the :c:type:`uv_udp_recv_cb` or :c:type:`uv_read_cb` callback. .. c:type:: void (*uv_close_cb)(uv_handle_t* handle) Type definition for callback passed to :c:func:`uv_close`. Public members ^^^^^^^^^^^^^^ .. c:member:: uv_loop_t* uv_handle_t.loop Pointer to the :c:type:`uv_loop_t` where the handle is running on. Readonly. .. c:member:: void* uv_handle_t.data Space for user-defined arbitrary data. libuv does not use this field. API --- .. c:function:: int uv_is_active(const uv_handle_t* handle) Returns non-zero if the handle is active, zero if it's inactive. What "active" means depends on the type of handle: - A uv_async_t handle is always active and cannot be deactivated, except by closing it with uv_close(). - A uv_pipe_t, uv_tcp_t, uv_udp_t, etc. handle - basically any handle that deals with i/o - is active when it is doing something that involves i/o, like reading, writing, connecting, accepting new connections, etc. - A uv_check_t, uv_idle_t, uv_timer_t, etc. handle is active when it has been started with a call to uv_check_start(), uv_idle_start(), etc. Rule of thumb: if a handle of type `uv_foo_t` has a `uv_foo_start()` function, then it's active from the moment that function is called. Likewise, `uv_foo_stop()` deactivates the handle again. .. c:function:: int uv_is_closing(const uv_handle_t* handle) Returns non-zero if the handle is closing or closed, zero otherwise. .. note:: This function should only be used between the initialization of the handle and the arrival of the close callback. .. c:function:: void uv_close(uv_handle_t* handle, uv_close_cb close_cb) Request handle to be closed. `close_cb` will be called asynchronously after this call. This MUST be called on each handle before memory is released. Handles that wrap file descriptors are closed immediately but `close_cb` will still be deferred to the next iteration of the event loop. It gives you a chance to free up any resources associated with the handle. In-progress requests, like uv_connect_t or uv_write_t, are cancelled and have their callbacks called asynchronously with status=UV_ECANCELED. .. c:function:: void uv_ref(uv_handle_t* handle) Reference the given handle. References are idempotent, that is, if a handle is already referenced calling this function again will have no effect. See :ref:`refcount`. .. c:function:: void uv_unref(uv_handle_t* handle) Un-reference the given handle. References are idempotent, that is, if a handle is not referenced calling this function again will have no effect. See :ref:`refcount`. .. c:function:: int uv_has_ref(const uv_handle_t* handle) Returns non-zero if the handle referenced, zero otherwise. See :ref:`refcount`. .. c:function:: size_t uv_handle_size(uv_handle_type type) Returns the size of the given handle type. Useful for FFI binding writers who don't want to know the structure layout. Miscellaneous API functions --------------------------- The following API functions take a :c:type:`uv_handle_t` argument but they work just for some handle types. .. c:function:: int uv_send_buffer_size(uv_handle_t* handle, int* value) Gets or sets the size of the send buffer that the operating system uses for the socket. If `*value` == 0, it will return the current send buffer size, otherwise it will use `*value` to set the new send buffer size. This function works for TCP, pipe and UDP handles on Unix and for TCP and UDP handles on Windows. .. note:: Linux will set double the size and return double the size of the original set value. .. c:function:: int uv_recv_buffer_size(uv_handle_t* handle, int* value) Gets or sets the size of the receive buffer that the operating system uses for the socket. If `*value` == 0, it will return the current receive buffer size, otherwise it will use `*value` to set the new receive buffer size. This function works for TCP, pipe and UDP handles on Unix and for TCP and UDP handles on Windows. .. note:: Linux will set double the size and return double the size of the original set value. .. c:function:: int uv_fileno(const uv_handle_t* handle, uv_os_fd_t* fd) Gets the platform dependent file descriptor equivalent. The following handles are supported: TCP, pipes, TTY, UDP and poll. Passing any other handle type will fail with `UV_EINVAL`. If a handle doesn't have an attached file descriptor yet or the handle itself has been closed, this function will return `UV_EBADF`. .. warning:: Be very careful when using this function. libuv assumes it's in control of the file descriptor so any change to it may lead to malfunction. .. _refcount: Reference counting ------------------ The libuv event loop (if run in the default mode) will run until there are no active `and` referenced handles left. The user can force the loop to exit early by unreferencing handles which are active, for example by calling :c:func:`uv_unref` after calling :c:func:`uv_timer_start`. A handle can be referenced or unreferenced, the refcounting scheme doesn't use a counter, so both operations are idempotent. All handles are referenced when active by default, see :c:func:`uv_is_active` for a more detailed explanation on what being `active` involves. libuv-v1.8.0/docs/src/idle.rst000066400000000000000000000022731263361716600162340ustar00rootroot00000000000000 .. _idle: :c:type:`uv_idle_t` --- Idle handle =================================== Idle handles will run the given callback once per loop iteration, right before the :c:type:`uv_prepare_t` handles. .. note:: The notable difference with prepare handles is that when there are active idle handles, the loop will perform a zero timeout poll instead of blocking for i/o. .. warning:: Despite the name, idle handles will get their callbacks called on every loop iteration, not when the loop is actually "idle".

It takes care of polling for i/o and scheduling callbacks to be run based on different sources of events. Data types ---------- .. c:type:: uv_loop_t Loop data type. .. c:type:: uv_run_mode Mode used to run the loop with :c:func:`uv_run`. :: typedef enum { UV_RUN_DEFAULT = 0, UV_RUN_ONCE, UV_RUN_NOWAIT } uv_run_mode; .. c:type:: void (*uv_walk_cb)(uv_handle_t* handle, void* arg) Type definition for callback passed to :c:func:`uv_walk`. Public members ^^^^^^^^^^^^^^ .. c:member:: void* uv_loop_t.data Space for user-defined arbitrary data. libuv does not use this field. libuv does, however, initialize it to NULL in :c:func:`uv_loop_init`, and it poisons the value (on debug builds) on :c:func:`uv_loop_close`. API --- .. c:function:: int uv_loop_init(uv_loop_t* loop) Initializes the given `uv_loop_t` structure. .. c:function:: int uv_loop_configure(uv_loop_t* loop, uv_loop_option option, ...) .. versionadded:: 1.0.2 Set additional loop options. You should normally call this before the first call to :c:func:`uv_run` unless mentioned otherwise. Returns 0 on success or a UV_E* error code on failure. Be prepared to handle UV_ENOSYS; it means the loop option is not supported by the platform. Supported options: - UV_LOOP_BLOCK_SIGNAL: Block a signal when polling for new events. The second argument to :c:func:`uv_loop_configure` is the signal number. This operation is currently only implemented for SIGPROF signals, to suppress unnecessary wakeups when using a sampling profiler. Requesting other signals will fail with UV_EINVAL. .. c:function:: int uv_loop_close(uv_loop_t* loop) Closes all internal loop resources. This function must only be called once the loop has finished its execution or it will return UV_EBUSY. After this function returns the user shall free the memory allocated for the loop. .. c:function:: uv_loop_t* uv_default_loop(void) Returns the initialized default loop. It may return NULL in case of allocation failure. This function is just a convenient way for having a global loop throughout an application, the default loop is in no way different than the ones initialized with :c:func:`uv_loop_init`. As such, the default loop can (and should) be closed with :c:func:`uv_loop_close` so the resources associated with it are freed. .. c:function:: int uv_run(uv_loop_t* loop, uv_run_mode mode) This function runs the event loop. It will act differently depending on the specified mode: - UV_RUN_DEFAULT: Runs the event loop until there are no more active and referenced handles or requests. Returns non-zero if :c:func:`uv_stop` was called and there are still active handles or requests. Returns zero in all other cases. - UV_RUN_ONCE: Poll for i/o once. Note that this function blocks if there are no pending callbacks. Returns zero when done (no active handles or requests left), or non-zero if more callbacks are expected (meaning you should run the event loop again sometime in the future). - UV_RUN_NOWAIT: Poll for i/o once but don't block if there are no pending callbacks. Returns zero if done (no active handles or requests left), or non-zero if more callbacks are expected (meaning you should run the event loop again sometime in the future). .. c:function:: int uv_loop_alive(const uv_loop_t* loop) Returns non-zero if there are active handles or request in the loop. .. c:function:: void uv_stop(uv_loop_t* loop) Stop the event loop, causing :c:func:`uv_run` to end as soon as possible. This will happen not sooner than the next loop iteration. If this function was called before blocking for i/o, the loop won't block for i/o on this iteration. .. c:function:: size_t uv_loop_size(void) Returns the size of the `uv_loop_t` structure. Useful for FFI binding writers who don't want to know the structure layout. .. c:function:: int uv_backend_fd(const uv_loop_t* loop) Get backend file descriptor. Only kqueue, epoll and event ports are supported. This can be used in conjunction with `uv_run(loop, UV_RUN_NOWAIT)` to poll in one thread and run the event loop's callbacks in another see test/test-embed.c for an example. .. note:: Embedding a kqueue fd in another kqueue pollset doesn't work on all platforms. It's not an error to add the fd but it never generates events. .. c:function:: int uv_backend_timeout(const uv_loop_t* loop) Get the poll timeout. The return value is in milliseconds, or -1 for no timeout. .. c:function:: uint64_t uv_now(const uv_loop_t* loop) Return the current timestamp in milliseconds. The timestamp is cached at the start of the event loop tick, see :c:func:`uv_update_time` for details and rationale. The timestamp increases monotonically from some arbitrary point in time. Don't make assumptions about the starting point, you will only get disappointed. .. note:: Use :c:func:`uv_hrtime` if you need sub-millisecond granularity. .. c:function:: void uv_update_time(uv_loop_t* loop) Update the event loop's concept of "now". Libuv caches the current time at the start of the event loop tick in order to reduce the number of time-related system calls. You won't normally need to call this function unless you have callbacks that block the event loop for longer periods of time, where "longer" is somewhat subjective but probably on the order of a millisecond or more. .. c:function:: void uv_walk(uv_loop_t* loop, uv_walk_cb walk_cb, void* arg) Walk the list of handles: `walk_cb` will be executed with the given `arg`. libuv-v1.8.0/docs/src/migration_010_100.rst000066400000000000000000000147501263361716600202530ustar00rootroot00000000000000 .. _migration_010_100: libuv 0.10 -> 1.0.0 migration guide =================================== Some APIs changed quite a bit throughout the 1.0.0 development process. Here is a migration guide for the most significant changes that happened after 0.10 was released. Loop initialization and closing ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ In libuv 0.10 (and previous versions), loops were created with `uv_loop_new`, which allocated memory for a new loop and initialized it; and destroyed with `uv_loop_delete`, which destroyed the loop and freed the memory. Starting with 1.0, those are deprecated and the user is responsible for allocating the memory and then initializing the loop. libuv 0.10 :: uv_loop_t* loop = uv_loop_new(); ... uv_loop_delete(loop); libuv 1.0 :: uv_loop_t* loop = malloc(sizeof *loop); uv_loop_init(loop); ... uv_loop_close(loop); free(loop); .. note:: Error handling was omitted for brevity. Check the documentation for :c:func:`uv_loop_init` and :c:func:`uv_loop_close`. Error handling ~~~~~~~~~~~~~~ Error handling had a major overhaul in libuv 1.0. In general, functions and status parameters would get 0 for success and -1 for failure on libuv 0.10, and the user had to use `uv_last_error` to fetch the error code, which was a positive number. In 1.0, functions and status parameters contain the actual error code, which is 0 for success, or a negative number in case of error. libuv 0.10 :: ... assume 'server' is a TCP server which is already listening r = uv_listen((uv_stream_t*) server, 511, NULL); if (r == -1) { uv_err_t err = uv_last_error(uv_default_loop()); /* err.code contains UV_EADDRINUSE */ } libuv 1.0 :: ... assume 'server' is a TCP server which is already listening r = uv_listen((uv_stream_t*) server, 511, NULL); if (r < 0) { /* r contains UV_EADDRINUSE */ } Threadpool changes ~~~~~~~~~~~~~~~~~~ In libuv 0.10 Unix used a threadpool which defaulted to 4 threads, while Windows used the `QueueUserWorkItem` API, which uses a Windows internal threadpool, which defaults to 512 threads per process. In 1.0, we unified both implementations, so Windows now uses the same implementation Unix does. The threadpool size can be set by exporting the ``UV_THREADPOOL_SIZE`` environment variable. See :c:ref:`threadpool`. Allocation callback API change ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ In libuv 0.10 the callback had to return a filled :c:type:`uv_buf_t` by value: :: uv_buf_t alloc_cb(uv_handle_t* handle, size_t size) { return uv_buf_init(malloc(size), size); } In libuv 1.0 a pointer to a buffer is passed to the callback, which the user needs to fill: :: void alloc_cb(uv_handle_t* handle, size_t size, uv_buf_t* buf) { buf->base = malloc(size); buf->len = size; } Unification of IPv4 / IPv6 APIs ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ libuv 1.0 unified the IPv4 and IPv6 APIS. There is no longer a `uv_tcp_bind` and `uv_tcp_bind6` duality, there is only :c:func:`uv_tcp_bind` now. IPv4 functions took ``struct sockaddr_in`` structures by value, and IPv6 functions took ``struct sockaddr_in6``. Now functions take a ``struct sockaddr*`` (note it's a pointer). It can be stack allocated. libuv 0.10 :: struct sockaddr_in addr = uv_ip4_addr("0.0.0.0", 1234); ... uv_tcp_bind(&server, addr) libuv 1.0 :: struct sockaddr_in addr; uv_ip4_addr("0.0.0.0", 1234, &addr) ... uv_tcp_bind(&server, (const struct sockaddr*) &addr, 0); The IPv4 and IPv6 struct creating functions (:c:func:`uv_ip4_addr` and :c:func:`uv_ip6_addr`) have also changed, make sure you check the documentation. ..note:: This change applies to all functions that made a distinction between IPv4 and IPv6 addresses. Streams / UDP data receive callback API change ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The streams and UDP data receive callbacks now get a pointer to a :c:type:`uv_buf_t` buffer, not a structure by value. libuv 0.10 :: void on_read(uv_stream_t* handle, ssize_t nread, uv_buf_t buf) { ... } void recv_cb(uv_udp_t* handle, ssize_t nread, uv_buf_t buf, struct sockaddr* addr, unsigned flags) { ... } libuv 1.0 :: void on_read(uv_stream_t* handle, ssize_t nread, const uv_buf_t* buf) { ... } void recv_cb(uv_udp_t* handle, ssize_t nread, const uv_buf_t* buf, const struct sockaddr* addr, unsigned flags) { ... } Receiving handles over pipes API change ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ In libuv 0.10 (and earlier versions) the `uv_read2_start` function was used to start reading data on a pipe, which could also result in the reception of handles over it. The callback for such function looked like this: :: void on_read(uv_pipe_t* pipe, ssize_t nread, uv_buf_t buf, uv_handle_type pending) { ... } In libuv 1.0, `uv_read2_start` was removed, and the user needs to check if there are pending handles using :c:func:`uv_pipe_pending_count` and :c:func:`uv_pipe_pending_type` while in the read callback: :: void on_read(uv_stream_t* handle, ssize_t nread, const uv_buf_t* buf) { ... while (uv_pipe_pending_count((uv_pipe_t*) handle) != 0) { pending = uv_pipe_pending_type((uv_pipe_t*) handle); ... } ... } Extracting the file descriptor out of a handle ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ While it wasn't supported by the API, users often accessed the libuv internals in order to get access to the file descriptor of a TCP handle, for example. :: fd = handle->io_watcher.fd; This is now properly exposed through the :c:func:`uv_fileno` function. uv_fs_readdir rename and API change ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ `uv_fs_readdir` returned a list of strings in the `req->ptr` field upon completion in libuv 0.10. In 1.0, this function got renamed to :c:func:`uv_fs_scandir`, since it's actually implemented using ``scandir(3)``. In addition, instead of allocating a full list strings, the user is able to get one result at a time by using the :c:func:`uv_fs_scandir_next` function. This function does not need to make a roundtrip to the threadpool, because libuv will keep the list of *dents* returned by ``scandir(3)`` around. libuv-v1.8.0/docs/src/misc.rst000066400000000000000000000250061263361716600162510ustar00rootroot00000000000000 .. _misc: Miscellaneous utilities ======================= This section contains miscellaneous functions that don't really belong in any other section.

This function must be called before any other libuv function is called or after all resources have been freed and thus libuv doesn't reference any allocated memory chunk. On success, it returns 0, if any of the function pointers is NULL it returns UV_EINVAL. .. warning:: There is no protection against changing the allocator multiple times. If the user changes it they are responsible for making sure the allocator is changed while no memory was allocated with the previous allocator, or that they are compatible. .. c:function:: uv_buf_t uv_buf_init(char* base, unsigned int len) Constructor for :c:type:`uv_buf_t`. Due to platform differences the user cannot rely on the ordering of the `base` and `len` members of the uv_buf_t struct. The user is responsible for freeing `base` after the uv_buf_t is done. Return struct passed by value. .. c:function:: char** uv_setup_args(int argc, char** argv) Store the program arguments. Required for getting / setting the process title. .. c:function:: int uv_get_process_title(char* buffer, size_t size) Gets the title of the current process. .. c:function:: int uv_set_process_title(const char* title) Sets the current process title. .. c:function:: int uv_resident_set_memory(size_t* rss) Gets the resident set size (RSS) for the current process. .. c:function:: int uv_uptime(double* uptime) Gets the current system uptime. .. c:function:: int uv_getrusage(uv_rusage_t* rusage) Gets the resource usage measures for the current process. .. note:: On Windows not all fields are set, the unsupported fields are filled with zeroes. .. c:function:: int uv_cpu_info(uv_cpu_info_t** cpu_infos, int* count) Gets information about the CPUs on the system. The `cpu_infos` array will have `count` elements and needs to be freed with :c:func:`uv_free_cpu_info`. .. c:function:: void uv_free_cpu_info(uv_cpu_info_t* cpu_infos, int count) Frees the `cpu_infos` array previously allocated with :c:func:`uv_cpu_info`. .. c:function:: int uv_interface_addresses(uv_interface_address_t** addresses, int* count) Gets address information about the network interfaces on the system. An array of `count` elements is allocated and returned in `addresses`. It must be freed by the user, calling :c:func:`uv_free_interface_addresses`. .. c:function:: void uv_free_interface_addresses(uv_interface_address_t* addresses, int count) Free an array of :c:type:`uv_interface_address_t` which was returned by :c:func:`uv_interface_addresses`. .. c:function:: void uv_loadavg(double avg[3]) Gets the load average.

On success they return 0. In case of error the target `dst` pointer is unmodified. .. c:function:: int uv_exepath(char* buffer, size_t* size) Gets the executable path. .. c:function:: int uv_cwd(char* buffer, size_t* size) Gets the current working directory. .. versionchanged:: 1.1.0 On Unix the path no longer ends in a slash. .. c:function:: int uv_chdir(const char* dir) Changes the current working directory. .. c:function:: int uv_os_homedir(char* buffer, size_t* size) Gets the current user's home directory. On Windows, `uv_os_homedir()` first checks the `USERPROFILE` environment variable using `GetEnvironmentVariableW()`. If `USERPROFILE` is not set, `GetUserProfileDirectoryW()` is called. On all other operating systems, `uv_os_homedir()` first checks the `HOME` environment variable using :man:`getenv(3)`. If `HOME` is not set, :man:`getpwuid_r(3)` is called. The user's home directory is stored in `buffer`. When `uv_os_homedir()` is called, `size` indicates the maximum size of `buffer`. On success or `UV_ENOBUFS` failure, `size` is set to the string length of `buffer`. .. warning:: `uv_os_homedir()` is not thread safe. .. versionadded:: 1.6.0 .. uint64_t uv_get_free_memory(void) .. c:function:: uint64_t uv_get_total_memory(void) Gets memory information (in bytes). .. c:function:: uint64_t uv_hrtime(void) Returns the current high-resolution real time. This is expressed in nanoseconds. It is relative to an arbitrary time in the past. It is not related to the time of day and therefore not subject to clock drift. The primary use is for measuring performance between intervals. .. note:: Not every platform can support nanosecond resolution; however, this value will always be in nanoseconds. .. c:function:: void uv_print_all_handles(uv_loop_t* loop, FILE* stream) Prints all handles associated with the given `loop` to the given `stream`. Example: :: uv_print_all_handles(uv_default_loop(), stderr); /* [--I] signal 0x1a25ea8 [-AI] async 0x1a25cf0 [R--] idle 0x1a7a8c8 */ The format is `[flags] handle-type handle-address`. For `flags`: - `R` is printed for a handle that is referenced - `A` is printed for a handle that is active - `I` is printed for a handle that is internal .. warning:: This function is meant for ad hoc debugging, there is no API/ABI stability guarantees. .. versionadded:: 1.8.0 .. c:function:: void uv_print_active_handles(uv_loop_t* loop, FILE* stream) This is the same as :c:func:`uv_print_all_handles` except only active handles are printed. .. warning:: This function is meant for ad hoc debugging, there is no API/ABI stability guarantees. .. versionadded:: 1.8.0 libuv-v1.8.0/docs/src/pipe.rst000066400000000000000000000064451263361716600162610ustar00rootroot00000000000000 .. _pipe: :c:type:`uv_pipe_t` --- Pipe handle =================================== Pipe handles provide an abstraction over local domain sockets on Unix and named pipes on Windows. :c:type:`uv_pipe_t` is a 'subclass' of :c:type:`uv_stream_t`. Data types ---------- .. c:type:: uv_pipe_t Pipe handle type. Public members ^^^^^^^^^^^^^^ N/A .. seealso:: The :c:type:`uv_stream_t` members also apply. API --- .. c:function:: int uv_pipe_init(uv_loop_t* loop, uv_pipe_t* handle, int ipc) Initialize a pipe handle. The `ipc` argument is a boolean to indicate if this pipe will be used for handle passing between processes. .. c:function:: int uv_pipe_open(uv_pipe_t* handle, uv_file file) Open an existing file descriptor or HANDLE as a pipe. .. versionchanged:: 1.2.1 the file descriptor is set to non-blocking mode. .. note:: The passed file descriptor or HANDLE is not checked for its type, but it's required that it represents a valid pipe. .. c:function:: int uv_pipe_bind(uv_pipe_t* handle, const char* name) Bind the pipe to a file path (Unix) or a name (Windows). .. note:: Paths on Unix get truncated to ``sizeof(sockaddr_un.sun_path)`` bytes, typically between 92 and 108 bytes. .. c:function:: void uv_pipe_connect(uv_connect_t* req, uv_pipe_t* handle, const char* name, uv_connect_cb cb) Connect to the Unix domain socket or the named pipe. .. note:: Paths on Unix get truncated to ``sizeof(sockaddr_un.sun_path)`` bytes, typically between 92 and 108 bytes. .. c:function:: int uv_pipe_getsockname(const uv_pipe_t* handle, char* buffer, size_t* size) Get the name of the Unix domain socket or the named pipe. A preallocated buffer must be provided. The size parameter holds the length of the buffer and it's set to the number of bytes written to the buffer on output. If the buffer is not big enough ``UV_ENOBUFS`` will be returned and len will contain the required size. .. versionchanged:: 1.3.0 the returned length no longer includes the terminating null byte, and the buffer is not null terminated. .. c:function:: int uv_pipe_getpeername(const uv_pipe_t* handle, char* buffer, size_t* size) Get the name of the Unix domain socket or the named pipe to which the handle is connected. A preallocated buffer must be provided. The size parameter holds the length of the buffer and it's set to the number of bytes written to the buffer on output. If the buffer is not big enough ``UV_ENOBUFS`` will be returned and len will contain the required size. .. versionadded:: 1.3.0 .. c:function:: void uv_pipe_pending_instances(uv_pipe_t* handle, int count) Set the number of pending pipe instance handles when the pipe server is waiting for connections. .. note:: This setting applies to Windows only. .. c:function:: int uv_pipe_pending_count(uv_pipe_t* handle) .. c:function:: uv_handle_type uv_pipe_pending_type(uv_pipe_t* handle) Used to receive handles over IPC pipes. First - call :c:func:`uv_pipe_pending_count`, if it's > 0 then initialize a handle of the given `type`, returned by :c:func:`uv_pipe_pending_type` and call ``uv_accept(pipe, handle)``. .. seealso:: The :c:type:`uv_stream_t` API functions also apply. libuv-v1.8.0/docs/src/poll.rst000066400000000000000000000066501263361716600162700ustar00rootroot00000000000000 .. _poll: :c:type:`uv_poll_t` --- Poll handle =================================== Poll handles are used to watch file descriptors for readability and writability, similar to the purpose of :man:`poll(2)`. The purpose of poll handles is to enable integrating external libraries that rely on the event loop to signal it about the socket status changes, like c-ares or libssh2. Using uv_poll_t for any other purpose is not recommended; :c:type:`uv_tcp_t`, :c:type:`uv_udp_t`, etc. provide an implementation that is faster and more scalable than what can be achieved with :c:type:`uv_poll_t`, especially on Windows. It is possible that poll handles occasionally signal that a file descriptor is readable or writable even when it isn't. The user should therefore always be prepared to handle EAGAIN or equivalent when it attempts to read from or write to the fd. It is not okay to have multiple active poll handles for the same socket, this can cause libuv to busyloop or otherwise malfunction. The user should not close a file descriptor while it is being polled by an active poll handle. This can cause the handle to report an error, but it might also start polling another socket. However the fd can be safely closed immediately after a call to :c:func:`uv_poll_stop` or :c:func:`uv_close`. .. note:: On windows only sockets can be polled with poll handles. On Unix any file descriptor that would be accepted by :man:`poll(2)` can be used. Data types ---------- .. c:type:: uv_poll_t Poll handle type. .. c:type:: void (*uv_poll_cb)(uv_poll_t* handle, int status, int events) Type definition for callback passed to :c:func:`uv_poll_start`. .. c:type:: uv_poll_event Poll event types :: enum uv_poll_event { UV_READABLE = 1, UV_WRITABLE = 2 }; Public members ^^^^^^^^^^^^^^ N/A .. seealso:: The :c:type:`uv_handle_t` members also apply. API --- .. c:function:: int uv_poll_init(uv_loop_t* loop, uv_poll_t* handle, int fd) Initialize the handle using a file descriptor. .. versionchanged:: 1.2.2 the file descriptor is set to non-blocking mode. .. c:function:: int uv_poll_init_socket(uv_loop_t* loop, uv_poll_t* handle, uv_os_sock_t socket) Initialize the handle using a socket descriptor. On Unix this is identical to :c:func:`uv_poll_init`. On windows it takes a SOCKET handle. .. versionchanged:: 1.2.2 the socket is set to non-blocking mode. .. c:function:: int uv_poll_start(uv_poll_t* handle, int events, uv_poll_cb cb) Starts polling the file descriptor. `events` is a bitmask consisting made up of UV_READABLE and UV_WRITABLE. As soon as an event is detected the callback will be called with `status` set to 0, and the detected events set on the `events` field. If an error happens while polling, `status` will be < 0 and corresponds with one of the UV_E* error codes (see :ref:`errors`). The user should not close the socket while the handle is active. If the user does that anyway, the callback *may* be called reporting an error status, but this is **not** guaranteed. .. note:: Calling :c:func:`uv_poll_start` on a handle that is already active is fine. Doing so will update the events mask that is being watched for. .. c:function:: int uv_poll_stop(uv_poll_t* poll) Stop polling the file descriptor, the callback will no longer be called. .. seealso:: The :c:type:`uv_handle_t` API functions also apply. libuv-v1.8.0/docs/src/prepare.rst000066400000000000000000000016411263361716600167530ustar00rootroot00000000000000 .. _prepare: :c:type:`uv_prepare_t` --- Prepare handle ========================================= Prepare handles will run the given callback once per loop iteration, right before polling for i/o. Data types ---------- .. c:type:: uv_prepare_t Prepare handle type. .. c:type:: void (*uv_prepare_cb)(uv_prepare_t* handle) Type definition for callback passed to :c:func:`uv_prepare_start`.

It's set after calling :c:func:`uv_spawn`. .. note:: The :c:type:`uv_handle_t` members also apply. .. c:member:: uv_process_options_t.exit_cb Callback called after the process exits. .. c:member:: uv_process_options_t.file Path pointing to the program to be executed. .. c:member:: uv_process_options_t.args Command line arguments. args[0] should be the path to the program. On Windows this uses `CreateProcess` which concatenates the arguments into a string this can cause some strange errors. See the ``UV_PROCESS_WINDOWS_VERBATIM_ARGUMENTS`` flag on :c:type:`uv_process_flags`. .. c:member:: uv_process_options_t.env Environment for the new process. If NULL the parents environment is used. .. c:member:: uv_process_options_t.cwd Current working directory for the subprocess. .. c:member:: uv_process_options_t.flags Various flags that control how :c:func:`uv_spawn` behaves. See :c:type:`uv_process_flags`. .. c:member:: uv_process_options_t.stdio_count .. c:member:: uv_process_options_t.stdio The `stdio` field points to an array of :c:type:`uv_stdio_container_t` structs that describe the file descriptors that will be made available to the child process. The convention is that stdio[0] points to stdin, fd 1 is used for stdout, and fd 2 is stderr. .. note:: On Windows file descriptors greater than 2 are available to the child process only if the child processes uses the MSVCRT runtime. .. c:member:: uv_process_options_t.uid .. c:member:: uv_process_options_t.gid Libuv can change the child process' user/group id. This happens only when the appropriate bits are set in the flags fields. .. note:: This is not supported on Windows, :c:func:`uv_spawn` will fail and set the error to ``UV_ENOTSUP``. .. c:member:: uv_stdio_container_t.flags Flags specifying how the stdio container should be passed to the child. See :c:type:`uv_stdio_flags`. .. c:member:: uv_stdio_container_t.data Union containing either the stream or fd to be passed on to the child process. API --- .. c:function:: void uv_disable_stdio_inheritance(void) Disables inheritance for file descriptors / handles that this process inherited from its parent. The effect is that child processes spawned by this process don't accidentally inherit these handles. It is recommended to call this function as early in your program as possible, before the inherited file descriptors can be closed or duplicated. .. note:: This function works on a best-effort basis: there is no guarantee that libuv can discover all file descriptors that were inherited. In general it does a better job on Windows than it does on Unix. .. c:function:: int uv_spawn(uv_loop_t* loop, uv_process_t* handle, const uv_process_options_t* options) Initializes the process handle and starts the process. If the process is successfully spawned, this function will return 0. Otherwise, the negative error code corresponding to the reason it couldn't spawn is returned. Possible reasons for failing to spawn would include (but not be limited to) the file to execute not existing, not having permissions to use the setuid or setgid specified, or not having enough memory to allocate for the new process. .. c:function:: int uv_process_kill(uv_process_t* handle, int signum) Sends the specified signal to the given process handle. Check the documentation on :c:ref:`signal` for signal support, specially on Windows. .. c:function:: int uv_kill(int pid, int signum) Sends the specified signal to the given PID. Check the documentation on :c:ref:`signal` for signal support, specially on Windows. .. seealso:: The :c:type:`uv_handle_t` API functions also apply. libuv-v1.8.0/docs/src/request.rst000066400000000000000000000040051263361716600170020ustar00rootroot00000000000000 .. _request: :c:type:`uv_req_t` --- Base request =================================== `uv_req_t` is the base type for all libuv request types. Structures are aligned so that any libuv request can be cast to `uv_req_t`. All API functions defined here work with any request type. Data types ---------- .. c:type:: uv_req_t The base libuv request structure. .. c:type:: uv_any_req Union of all request types. Public members ^^^^^^^^^^^^^^ .. c:member:: void* uv_req_t.data Space for user-defined arbitrary data. libuv does not use this field. .. c:member:: uv_req_type uv_req_t.type Indicated the type of request. Readonly. :: typedef enum { UV_UNKNOWN_REQ = 0, UV_REQ, UV_CONNECT, UV_WRITE, UV_SHUTDOWN, UV_UDP_SEND, UV_FS, UV_WORK, UV_GETADDRINFO, UV_GETNAMEINFO, UV_REQ_TYPE_PRIVATE, UV_REQ_TYPE_MAX, } uv_req_type; API --- .. c:function:: int uv_cancel(uv_req_t* req) Cancel a pending request. Fails if the request is executing or has finished executing. Returns 0 on success, or an error code < 0 on failure. Only cancellation of :c:type:`uv_fs_t`, :c:type:`uv_getaddrinfo_t`, :c:type:`uv_getnameinfo_t` and :c:type:`uv_work_t` requests is currently supported. Cancelled requests have their callbacks invoked some time in the future. It's **not** safe to free the memory associated with the request until the callback is called. Here is how cancellation is reported to the callback: * A :c:type:`uv_fs_t` request has its req->result field set to `UV_ECANCELED`. * A :c:type:`uv_work_t`, :c:type:`uv_getaddrinfo_t` or c:type:`uv_getnameinfo_t` request has its callback invoked with status == `UV_ECANCELED`. .. c:function:: size_t uv_req_size(uv_req_type type) Returns the size of the given request type. Useful for FFI binding writers who don't want to know the structure layout. libuv-v1.8.0/docs/src/signal.rst000066400000000000000000000047331263361716600165770ustar00rootroot00000000000000 .. _signal: :c:type:`uv_signal_t` --- Signal handle ======================================= Signal handles implement Unix style signal handling on a per-event loop bases. Reception of some signals is emulated on Windows: * SIGINT is normally delivered when the user presses CTRL+C. However, like on Unix, it is not generated when terminal raw mode is enabled. * SIGBREAK is delivered when the user pressed CTRL + BREAK. * SIGHUP is generated when the user closes the console window. On SIGHUP the program is given approximately 10 seconds to perform cleanup. After that Windows will unconditionally terminate it. * SIGWINCH is raised whenever libuv detects that the console has been resized. SIGWINCH is emulated by libuv when the program uses a :c:type:`uv_tty_t` handle to write to the console. SIGWINCH may not always be delivered in a timely manner; libuv will only detect size changes when the cursor is being moved. When a readable :c:type:`uv_tty_t` handle is used in raw mode, resizing the console buffer will also trigger a SIGWINCH signal. Watchers for other signals can be successfully created, but these signals are never received. These signals are: `SIGILL`, `SIGABRT`, `SIGFPE`, `SIGSEGV`, `SIGTERM` and `SIGKILL.` Calls to raise() or abort() to programmatically raise a signal are not detected by libuv; these will not trigger a signal watcher. .. note:: On Linux SIGRT0 and SIGRT1 (signals 32 and 33) are used by the NPTL pthreads library to manage threads. Installing watchers for those signals will lead to unpredictable behavior and is strongly discouraged. Future versions of libuv may simply reject them.

Data types ---------- .. c:type:: uv_stream_t Stream handle type. .. c:type:: uv_connect_t Connect request type. .. c:type:: uv_shutdown_t Shutdown request type. .. c:type:: uv_write_t Write request type. .. c:type:: void (*uv_read_cb)(uv_stream_t* stream, ssize_t nread, const uv_buf_t* buf) Callback called when data was read on a stream. `nread` is > 0 if there is data available or < 0 on error. When we've reached EOF, `nread` will be set to ``UV_EOF``. When `nread` < 0, the `buf` parameter might not point to a valid buffer; in that case `buf.len` and `buf.base` are both set to 0. .. note:: `nread` might be 0, which does *not* indicate an error or EOF. This is equivalent to ``EAGAIN`` or ``EWOULDBLOCK`` under ``read(2)``. The callee is responsible for stopping closing the stream when an error happens by calling :c:func:`uv_read_stop` or :c:func:`uv_close`. Trying to read from the stream again is undefined. The callee is responsible for freeing the buffer, libuv does not reuse it. The buffer may be a null buffer (where buf->base=NULL and buf->len=0) on error. .. c:type:: void (*uv_write_cb)(uv_write_t* req, int status) Callback called after data was written on a stream. `status` will be 0 in case of success, < 0 otherwise. .. c:type:: void (*uv_connect_cb)(uv_connect_t* req, int status) Callback called after a connection started by :c:func:`uv_connect` is done. `status` will be 0 in case of success, < 0 otherwise. .. c:type:: void (*uv_shutdown_cb)(uv_shutdown_t* req, int status) Callback called after s shutdown request has been completed. `status` will be 0 in case of success, < 0 otherwise. .. c:type:: void (*uv_connection_cb)(uv_stream_t* server, int status) Callback called when a stream server has received an incoming connection. The user can accept the connection by calling :c:func:`uv_accept`. `status` will be 0 in case of success, < 0 otherwise. Public members ^^^^^^^^^^^^^^ .. c:member:: size_t uv_stream_t.write_queue_size Contains the amount of queued bytes waiting to be sent. Readonly. .. c:member:: uv_stream_t* uv_connect_t.handle Pointer to the stream where this connection request is running. .. c:member:: uv_stream_t* uv_shutdown_t.handle Pointer to the stream where this shutdown request is running. .. c:member:: uv_stream_t* uv_write_t.handle Pointer to the stream where this write request is running. .. c:member:: uv_stream_t* uv_write_t.send_handle Pointer to the stream being sent using this write request.. .. seealso:: The :c:type:`uv_handle_t` members also apply. API --- .. c:function:: int uv_shutdown(uv_shutdown_t* req, uv_stream_t* handle, uv_shutdown_cb cb) Shutdown the outgoing (write) side of a duplex stream. It waits for pending write requests to complete. The `handle` should refer to a initialized stream. `req` should be an uninitialized shutdown request struct. The `cb` is called after shutdown is complete. .. c:function:: int uv_listen(uv_stream_t* stream, int backlog, uv_connection_cb cb) Start listening for incoming connections. `backlog` indicates the number of connections the kernel might queue, same as :man:`listen(2)`. When a new incoming connection is received the :c:type:`uv_connection_cb` callback is called. .. c:function:: int uv_accept(uv_stream_t* server, uv_stream_t* client) This call is used in conjunction with :c:func:`uv_listen` to accept incoming connections. Call this function after receiving a :c:type:`uv_connection_cb` to accept the connection. Before calling this function the client handle must be initialized. < 0 return value indicates an error. When the :c:type:`uv_connection_cb` callback is called it is guaranteed that this function will complete successfully the first time. If you attempt to use it more than once, it may fail. It is suggested to only call this function once per :c:type:`uv_connection_cb` call. .. note:: `server` and `client` must be handles running on the same loop. .. c:function:: int uv_read_start(uv_stream_t* stream, uv_alloc_cb alloc_cb, uv_read_cb read_cb) Read data from an incoming stream. The :c:type:`uv_read_cb` callback will be made several times until there is no more data to read or :c:func:`uv_read_stop` is called. .. c:function:: int uv_read_stop(uv_stream_t*) Stop reading data from the stream. The :c:type:`uv_read_cb` callback will no longer be called. This function is idempotent and may be safely called on a stopped stream. .. c:function:: int uv_write(uv_write_t* req, uv_stream_t* handle, const uv_buf_t bufs[], unsigned int nbufs, uv_write_cb cb) Write data to stream. Buffers are written in order. Example: :: uv_buf_t a[] = { { .base = "1", .len = 1 }, { .base = "2", .len = 1 } }; uv_buf_t b[] = { { .base = "3", .len = 1 }, { .base = "4", .len = 1 } }; uv_write_t req1; uv_write_t req2; /* writes "1234" */ uv_write(&req1, stream, a, 2); uv_write(&req2, stream, b, 2); .. c:function:: int uv_write2(uv_write_t* req, uv_stream_t* handle, const uv_buf_t bufs[], unsigned int nbufs, uv_stream_t* send_handle, uv_write_cb cb) Extended write function for sending handles over a pipe. The pipe must be initialized with `ipc` == 1. .. note:: `send_handle` must be a TCP socket or pipe, which is a server or a connection (listening or connected state). Bound sockets or pipes will be assumed to be servers. .. c:function:: int uv_try_write(uv_stream_t* handle, const uv_buf_t bufs[], unsigned int nbufs) Same as :c:func:`uv_write`, but won't queue a write request if it can't be completed immediately. Will return either: * > 0: number of bytes written (can be less than the supplied buffer size). * < 0: negative error code (``UV_EAGAIN`` is returned if no data can be sent immediately). .. c:function:: int uv_is_readable(const uv_stream_t* handle) Returns 1 if the stream is readable, 0 otherwise. .. c:function:: int uv_is_writable(const uv_stream_t* handle) Returns 1 if the stream is writable, 0 otherwise. .. c:function:: int uv_stream_set_blocking(uv_stream_t* handle, int blocking) Enable or disable blocking mode for a stream. When blocking mode is enabled all writes complete synchronously. The interface remains unchanged otherwise, e.g. completion or failure of the operation will still be reported through a callback which is made asynchronously. .. warning:: Relying too much on this API is not recommended. It is likely to change significantly in the future. Currently only works on Windows for :c:type:`uv_pipe_t` handles. On UNIX platforms, all :c:type:`uv_stream_t` handles are supported. Also libuv currently makes no ordering guarantee when the blocking mode is changed after write requests have already been submitted. Therefore it is recommended to set the blocking mode immediately after opening or creating the stream. .. versionchanged:: 1.4.0 UNIX implementation added. .. seealso:: The :c:type:`uv_handle_t` API functions also apply. libuv-v1.8.0/docs/src/tcp.rst000066400000000000000000000075251263361716600161120ustar00rootroot00000000000000 .. _tcp: :c:type:`uv_tcp_t` --- TCP handle ================================= TCP handles are used to represent both TCP streams and servers. :c:type:`uv_tcp_t` is a 'subclass' of :c:type:`uv_stream_t`. Data types ---------- .. c:type:: uv_tcp_t TCP handle type. Public members ^^^^^^^^^^^^^^ N/A .. seealso:: The :c:type:`uv_stream_t` members also apply. API --- .. c:function:: int uv_tcp_init(uv_loop_t* loop, uv_tcp_t* handle) Initialize the handle. No socket is created as of yet. .. c:function:: int uv_tcp_init_ex(uv_loop_t* loop, uv_tcp_t* handle, unsigned int flags) Initialize the handle with the specified flags. At the moment only the lower 8 bits of the `flags` parameter are used as the socket domain. A socket will be created for the given domain. If the specified domain is ``AF_UNSPEC`` no socket is created, just like :c:func:`uv_tcp_init`. .. versionadded:: 1.7.0 .. c:function:: int uv_tcp_open(uv_tcp_t* handle, uv_os_sock_t sock) Open an existing file descriptor or SOCKET as a TCP handle. .. versionchanged:: 1.2.1 the file descriptor is set to non-blocking mode. .. note:: The passed file descriptor or SOCKET is not checked for its type, but it's required that it represents a valid stream socket. .. c:function:: int uv_tcp_nodelay(uv_tcp_t* handle, int enable) Enable / disable Nagle's algorithm. .. c:function:: int uv_tcp_keepalive(uv_tcp_t* handle, int enable, unsigned int delay) Enable / disable TCP keep-alive. `delay` is the initial delay in seconds, ignored when `enable` is zero. .. c:function:: int uv_tcp_simultaneous_accepts(uv_tcp_t* handle, int enable) Enable / disable simultaneous asynchronous accept requests that are queued by the operating system when listening for new TCP connections. This setting is used to tune a TCP server for the desired performance. Having simultaneous accepts can significantly improve the rate of accepting connections (which is why it is enabled by default) but may lead to uneven load distribution in multi-process setups. .. c:function:: int uv_tcp_bind(uv_tcp_t* handle, const struct sockaddr* addr, unsigned int flags) Bind the handle to an address and port. `addr` should point to an initialized ``struct sockaddr_in`` or ``struct sockaddr_in6``. When the port is already taken, you can expect to see an ``UV_EADDRINUSE`` error from either :c:func:`uv_tcp_bind`, :c:func:`uv_listen` or :c:func:`uv_tcp_connect`. That is, a successful call to this function does not guarantee that the call to :c:func:`uv_listen` or :c:func:`uv_tcp_connect` will succeed as well. `flags` can contain ``UV_TCP_IPV6ONLY``, in which case dual-stack support is disabled and only IPv6 is used. .. c:function:: int uv_tcp_getsockname(const uv_tcp_t* handle, struct sockaddr* name, int* namelen) Get the current address to which the handle is bound. `addr` must point to a valid and big enough chunk of memory, ``struct sockaddr_storage`` is recommended for IPv4 and IPv6 support. .. c:function:: int uv_tcp_getpeername(const uv_tcp_t* handle, struct sockaddr* name, int* namelen) Get the address of the peer connected to the handle. `addr` must point to a valid and big enough chunk of memory, ``struct sockaddr_storage`` is recommended for IPv4 and IPv6 support. .. c:function:: int uv_tcp_connect(uv_connect_t* req, uv_tcp_t* handle, const struct sockaddr* addr, uv_connect_cb cb) Establish an IPv4 or IPv6 TCP connection. Provide an initialized TCP handle and an uninitialized :c:type:`uv_connect_t`. `addr` should point to an initialized ``struct sockaddr_in`` or ``struct sockaddr_in6``. The callback is made when the connection has been established or when a connection error happened. .. seealso:: The :c:type:`uv_stream_t` API functions also apply. libuv-v1.8.0/docs/src/threading.rst000066400000000000000000000106771263361716600172730ustar00rootroot00000000000000 .. _threading: Threading and synchronization utilities ======================================= libuv provides cross-platform implementations for multiple threading and synchronization primitives. The API largely follows the pthreads API. Data types ---------- .. c:type:: uv_thread_t Thread data type. .. c:type:: void (*uv_thread_cb)(void* arg) Callback that is invoked to initialize thread execution. `arg` is the same value that was passed to :c:func:`uv_thread_create`. .. c:type:: uv_key_t Thread-local key data type. .. c:type:: uv_once_t Once-only initializer data type. .. c:type:: uv_mutex_t Mutex data type. .. c:type:: uv_rwlock_t Read-write lock data type. .. c:type:: uv_sem_t Semaphore data type. .. c:type:: uv_cond_t Condition data type. .. c:type:: uv_barrier_t Barrier data type. API --- Threads ^^^^^^^ .. c:function:: int uv_thread_create(uv_thread_t* tid, uv_thread_cb entry, void* arg) .. versionchanged:: 1.4.1 returns a UV_E* error code on failure .. c:function:: uv_thread_t uv_thread_self(void) .. c:function:: int uv_thread_join(uv_thread_t *tid) .. c:function:: int uv_thread_equal(const uv_thread_t* t1, const uv_thread_t* t2) Thread-local storage ^^^^^^^^^^^^^^^^^^^^ .. note:: The total thread-local storage size may be limited.

This thread pool is internally used to run all filesystem operations, as well as getaddrinfo and getnameinfo requests. Its default size is 4, but it can be changed at startup time by setting the ``UV_THREADPOOL_SIZE`` environment variable to any value (the absolute maximum is 128). The threadpool is global and shared across all event loops. When a particular function makes use of the threadpool (i.e. when using :c:func:`uv_queue_work`) libuv preallocates and initializes the maximum number of threads allowed by ``UV_THREADPOOL_SIZE``. This causes a relatively minor memory overhead (~1MB for 128 threads) but increases the performance of threading at runtime. .. note:: Note that even though a global thread pool which is shared across all events loops is used, the functions are not thread safe. Data types ---------- .. c:type:: uv_work_t Work request type. .. c:type:: void (*uv_work_cb)(uv_work_t* req) Callback passed to :c:func:`uv_queue_work` which will be run on the thread pool. .. c:type:: void (*uv_after_work_cb)(uv_work_t* req, int status) Callback passed to :c:func:`uv_queue_work` which will be called on the loop thread after the work on the threadpool has been completed. If the work was cancelled using :c:func:`uv_cancel` `status` will be ``UV_ECANCELED``. Public members ^^^^^^^^^^^^^^ .. c:member:: uv_loop_t* uv_work_t.loop Loop that started this request and where completion will be reported. Readonly. .. seealso:: The :c:type:`uv_req_t` members also apply. API --- .. c:function:: int uv_queue_work(uv_loop_t* loop, uv_work_t* req, uv_work_cb work_cb, uv_after_work_cb after_work_cb) Initializes a work request which will run the given `work_cb` in a thread from the threadpool. Once `work_cb` is completed, `after_work_cb` will be called on the loop thread. This request can be cancelled with :c:func:`uv_cancel`. .. seealso:: The :c:type:`uv_req_t` API functions also apply. libuv-v1.8.0/docs/src/timer.rst000066400000000000000000000044261263361716600164410ustar00rootroot00000000000000 .. _timer: :c:type:`uv_timer_t` --- Timer handle ===================================== Timer handles are used to schedule callbacks to be called in the future. Data types ---------- .. c:type:: uv_timer_t Timer handle type. .. c:type:: void (*uv_timer_cb)(uv_timer_t* handle) Type definition for callback passed to :c:func:`uv_timer_start`. Public members ^^^^^^^^^^^^^^ N/A .. seealso:: The :c:type:`uv_handle_t` members also apply. API --- .. c:function:: int uv_timer_init(uv_loop_t* loop, uv_timer_t* handle) Initialize the handle. .. c:function:: int uv_timer_start(uv_timer_t* handle, uv_timer_cb cb, uint64_t timeout, uint64_t repeat) Start the timer. `timeout` and `repeat` are in milliseconds. If `timeout` is zero, the callback fires on the next event loop iteration. If `repeat` is non-zero, the callback fires first after `timeout` milliseconds and then repeatedly after `repeat` milliseconds. .. c:function:: int uv_timer_stop(uv_timer_t* handle) Stop the timer, the callback will not be called anymore. .. c:function:: int uv_timer_again(uv_timer_t* handle) Stop the timer, and if it is repeating restart it using the repeat value as the timeout. If the timer has never been started before it returns UV_EINVAL. .. c:function:: void uv_timer_set_repeat(uv_timer_t* handle, uint64_t repeat) Set the repeat interval value in milliseconds. The timer will be scheduled to run on the given interval, regardless of the callback execution duration, and will follow normal timer semantics in the case of a time-slice overrun. For example, if a 50ms repeating timer first runs for 17ms, it will be scheduled to run again 33ms later. If other tasks consume more than the 33ms following the first timer callback, then the callback will run as soon as possible. .. note:: If the repeat value is set from a timer callback it does not immediately take effect. If the timer was non-repeating before, it will have been stopped. If it was repeating, then the old repeat value will have been used to schedule the next timeout. .. c:function:: uint64_t uv_timer_get_repeat(const uv_timer_t* handle) Get the timer repeat value. .. seealso:: The :c:type:`uv_handle_t` API functions also apply. libuv-v1.8.0/docs/src/tty.rst000066400000000000000000000046501263361716600161400ustar00rootroot00000000000000 .. _tty: :c:type:`uv_tty_t` --- TTY handle ================================= TTY handles represent a stream for the console. :c:type:`uv_tty_t` is a 'subclass' of :c:type:`uv_stream_t`.

API --- .. c:function:: int uv_tty_init(uv_loop_t* loop, uv_tty_t* handle, uv_file fd, int readable) Initialize a new TTY stream with the given file descriptor. Usually the file descriptor will be: * 0 = stdin * 1 = stdout * 2 = stderr `readable`, specifies if you plan on calling :c:func:`uv_read_start` with this stream. stdin is readable, stdout is not. On Unix this function will try to open ``/dev/tty`` and use it if the passed file descriptor refers to a TTY. This lets libuv put the tty in non-blocking mode without affecting other processes that share the tty. .. note:: If opening ``/dev/tty`` fails, libuv falls back to blocking writes for non-readable TTY streams. .. versionchanged:: 1.5.0: trying to initialize a TTY stream with a file descriptor that refers to a file returns `UV_EINVAL` on UNIX. .. c:function:: int uv_tty_set_mode(uv_tty_t* handle, uv_tty_mode_t mode) .. versionchanged:: 1.2.0: the mode is specified as a :c:type:`uv_tty_mode_t` value. Set the TTY using the specified terminal mode. .. c:function:: int uv_tty_reset_mode(void) To be called when the program exits. Resets TTY settings to default values for the next process to take over. This function is async signal-safe on Unix platforms but can fail with error code ``UV_EBUSY`` if you call it when execution is inside :c:func:`uv_tty_set_mode`. .. c:function:: int uv_tty_get_winsize(uv_tty_t* handle, int* width, int* height) Gets the current Window size. On success it returns 0. .. seealso:: The :c:type:`uv_stream_t` API functions also apply. libuv-v1.8.0/docs/src/udp.rst000066400000000000000000000235171263361716600161130ustar00rootroot00000000000000 .. _udp: :c:type:`uv_udp_t` --- UDP handle ================================= UDP handles encapsulate UDP communication for both clients and servers.

Used in uv_udp_recv_cb. */ UV_UDP_PARTIAL = 2, /* * Indicates if SO_REUSEADDR will be set when binding the handle in * uv_udp_bind. * This sets the SO_REUSEPORT socket flag on the BSDs and OS X. On other * Unix platforms, it sets the SO_REUSEADDR flag. What that means is that * multiple threads or processes can bind to the same address without error * (provided they all set the flag) but only the last one to bind will receive * any traffic, in effect "stealing" the port from the previous listener. */ UV_UDP_REUSEADDR = 4 }; .. c:type:: void (*uv_udp_send_cb)(uv_udp_send_t* req, int status) Type definition for callback passed to :c:func:`uv_udp_send`, which is called after the data was sent. .. c:type:: void (*uv_udp_recv_cb)(uv_udp_t* handle, ssize_t nread, const uv_buf_t* buf, const struct sockaddr* addr, unsigned flags) Type definition for callback passed to :c:func:`uv_udp_recv_start`, which is called when the endpoint receives data. * `handle`: UDP handle * `nread`: Number of bytes that have been received. 0 if there is no more data to read. You may discard or repurpose the read buffer. Note that 0 may also mean that an empty datagram was received (in this case `addr` is not NULL). < 0 if a transmission error was detected. * `buf`: :c:type:`uv_buf_t` with the received data. * `addr`: ``struct sockaddr*`` containing the address of the sender. Can be NULL. Valid for the duration of the callback only. * `flags`: One or more or'ed UV_UDP_* constants. Right now only ``UV_UDP_PARTIAL`` is used. .. note:: The receive callback will be called with `nread` == 0 and `addr` == NULL when there is nothing to read, and with `nread` == 0 and `addr` != NULL when an empty UDP packet is received. .. c:type:: uv_membership Membership type for a multicast address. :: typedef enum { UV_LEAVE_GROUP = 0, UV_JOIN_GROUP } uv_membership; Public members ^^^^^^^^^^^^^^ .. c:member:: size_t uv_udp_t.send_queue_size Number of bytes queued for sending. This field strictly shows how much information is currently queued. .. c:member:: size_t uv_udp_t.send_queue_count Number of send requests currently in the queue awaiting to be processed. .. c:member:: uv_udp_t* uv_udp_send_t.handle UDP handle where this send request is taking place. .. seealso:: The :c:type:`uv_handle_t` members also apply. API --- .. c:function:: int uv_udp_init(uv_loop_t* loop, uv_udp_t* handle) Initialize a new UDP handle. The actual socket is created lazily. Returns 0 on success. .. c:function:: int uv_udp_init_ex(uv_loop_t* loop, uv_udp_t* handle, unsigned int flags) Initialize the handle with the specified flags. At the moment the lower 8 bits of the `flags` parameter are used as the socket domain. A socket will be created for the given domain. If the specified domain is ``AF_UNSPEC`` no socket is created, just like :c:func:`uv_udp_init`. .. versionadded:: 1.7.0 .. c:function:: int uv_udp_open(uv_udp_t* handle, uv_os_sock_t sock) Opens an existing file descriptor or Windows SOCKET as a UDP handle. Unix only: The only requirement of the `sock` argument is that it follows the datagram contract (works in unconnected mode, supports sendmsg()/recvmsg(), etc). In other words, other datagram-type sockets like raw sockets or netlink sockets can also be passed to this function. .. versionchanged:: 1.2.1 the file descriptor is set to non-blocking mode. .. note:: The passed file descriptor or SOCKET is not checked for its type, but it's required that it represents a valid datagram socket. .. c:function:: int uv_udp_bind(uv_udp_t* handle, const struct sockaddr* addr, unsigned int flags) Bind the UDP handle to an IP address and port. :param handle: UDP handle.

The * amortized cost for a sequence of m accesses to a splay tree is O(lg n); * * A red-black tree is a binary search tree with the node color as an * extra attribute. It fulfills a set of conditions: * - every search path from the root to a leaf consists of the * same number of black nodes, * - each red node (except for the root) has a black parent, * - each leaf node is black. * * Every operation on a red-black tree is bounded as O(lg n). * The maximum height of a red-black tree is 2lg (n+1). */ #define SPLAY_HEAD(name, type) \ struct name { \ struct type *sph_root;

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. */ enum conn_state { c_busy, /* Busy; waiting for incoming data or for a write to complete. */ c_done, /* Done; read incoming data or write finished. */ c_stop, /* Stopped. */ c_dead }; /* Session states. */ enum sess_state { s_handshake, /* Wait for client handshake. */ s_handshake_auth, /* Wait for client authentication data. */ s_req_start, /* Start waiting for request data. */ s_req_parse, /* Wait for request data. */ s_req_lookup, /* Wait for upstream hostname DNS lookup to complete. */ s_req_connect, /* Wait for uv_tcp_connect() to complete. */ s_proxy_start, /* Connected.

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. It verifies that a watcher is * implicitly stopped when closed, and that a watcher can close itself * safely. * - There is a repeating timer. It does not keep the event loop alive * (ev_unref) but makes sure that the loop keeps polling the system for * events. */ #include "uv.h" #include "task.h" #include #define IDLE_COUNT 7 #define ITERATIONS 21 #define TIMEOUT 100 static uv_prepare_t prepare_1_handle; static uv_prepare_t prepare_2_handle; static uv_check_t check_handle; static uv_idle_t idle_1_handles[IDLE_COUNT]; static uv_idle_t idle_2_handle; static uv_timer_t timer_handle; static int loop_iteration = 0; static int prepare_1_cb_called = 0; static int prepare_1_close_cb_called = 0; static int prepare_2_cb_called = 0; static int prepare_2_close_cb_called = 0; static int check_cb_called = 0; static int check_close_cb_called = 0; static int idle_1_cb_called = 0; static int idle_1_close_cb_called = 0; static int idles_1_active = 0; static int idle_2_cb_called = 0; static int idle_2_close_cb_called = 0; static int idle_2_cb_started = 0; static int idle_2_is_active = 0; static void timer_cb(uv_timer_t* handle) { ASSERT(handle == &timer_handle); } static void idle_2_close_cb(uv_handle_t* handle) { fprintf(stderr, "%s", "IDLE_2_CLOSE_CB\n"); fflush(stderr); ASSERT(handle == (uv_handle_t*)&idle_2_handle); ASSERT(idle_2_is_active); idle_2_close_cb_called++; idle_2_is_active = 0; } static void idle_2_cb(uv_idle_t* handle) { fprintf(stderr, "%s", "IDLE_2_CB\n"); fflush(stderr); ASSERT(handle == &idle_2_handle); idle_2_cb_called++; uv_close((uv_handle_t*)handle, idle_2_close_cb); } static void idle_1_cb(uv_idle_t* handle) { int r; fprintf(stderr, "%s", "IDLE_1_CB\n"); fflush(stderr); ASSERT(handle != NULL); ASSERT(idles_1_active > 0); /* Init idle_2 and make it active */ if (!idle_2_is_active && !uv_is_closing((uv_handle_t*)&idle_2_handle)) { r = uv_idle_init(uv_default_loop(), &idle_2_handle); ASSERT(r == 0); r = uv_idle_start(&idle_2_handle, idle_2_cb); ASSERT(r == 0); idle_2_is_active = 1; idle_2_cb_started++; } idle_1_cb_called++; if (idle_1_cb_called % 5 == 0) { r = uv_idle_stop((uv_idle_t*)handle); ASSERT(r == 0); idles_1_active--; } } static void idle_1_close_cb(uv_handle_t* handle) { fprintf(stderr, "%s", "IDLE_1_CLOSE_CB\n"); fflush(stderr); ASSERT(handle != NULL); idle_1_close_cb_called++; } static void prepare_1_close_cb(uv_handle_t* handle) { fprintf(stderr, "%s", "PREPARE_1_CLOSE_CB"); fflush(stderr); ASSERT(handle == (uv_handle_t*)&prepare_1_handle); prepare_1_close_cb_called++; } static void check_close_cb(uv_handle_t* handle) { fprintf(stderr, "%s", "CHECK_CLOSE_CB\n"); fflush(stderr); ASSERT(handle == (uv_handle_t*)&check_handle); check_close_cb_called++; } static void prepare_2_close_cb(uv_handle_t* handle) { fprintf(stderr, "%s", "PREPARE_2_CLOSE_CB\n"); fflush(stderr); ASSERT(handle == (uv_handle_t*)&prepare_2_handle); prepare_2_close_cb_called++; } static void check_cb(uv_check_t* handle) { int i, r; fprintf(stderr, "%s", "CHECK_CB\n"); fflush(stderr); ASSERT(handle == &check_handle); if (loop_iteration < ITERATIONS) { /* Make some idle watchers active */ for (i = 0; i < 1 + (loop_iteration % IDLE_COUNT); i++) { r = uv_idle_start(&idle_1_handles[i], idle_1_cb); ASSERT(r == 0); idles_1_active++; } } else { /* End of the test - close all handles */ uv_close((uv_handle_t*)&prepare_1_handle, prepare_1_close_cb); uv_close((uv_handle_t*)&check_handle, check_close_cb); uv_close((uv_handle_t*)&prepare_2_handle, prepare_2_close_cb); for (i = 0; i < IDLE_COUNT; i++) { uv_close((uv_handle_t*)&idle_1_handles[i], idle_1_close_cb); } /* This handle is closed/recreated every time, close it only if it is */ /* active.*/ if (idle_2_is_active) { uv_close((uv_handle_t*)&idle_2_handle, idle_2_close_cb); } } check_cb_called++; } static void prepare_2_cb(uv_prepare_t* handle) { int r; fprintf(stderr, "%s", "PREPARE_2_CB\n"); fflush(stderr); ASSERT(handle == &prepare_2_handle); /* prepare_2 gets started by prepare_1 when (loop_iteration % 2 == 0), */ /* and it stops itself immediately.
