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][] 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. Each new test needs to be registered in `test/test-list.h`. If you add a new test file, it needs to be registered in two places: +- `Makefile.am`: add the file's name to the `test_run_tests_SOURCES` list. +- `uv.gyp`: add the file's name to the `sources` list in the `run-tests` target. + +Look at other tests to see how they should be structured (license boilerplate, +the way entry points are declared, etc.). + +Check README.md file to find out how to run the test suite and make sure that +there are no test regressions. + +### PUSH + +``` +$ git push origin my-feature-branch +``` + +Go to https://github.com/username/libuv and select your feature branch. Click +the 'Pull Request' button and fill out the form. + +Pull requests are usually reviewed within a few days. If there are comments +to address, apply your changes in a separate commit and push that to your +feature branch. Post a comment in the pull request afterwards; GitHub does +not send out notifications when you add commits. + + +[issue tracker]: https://github.com/libuv/libuv/issues +[libuv mailing list]:

The new platform +will need to implement some of the functions, the prototypes are in +``src/unix/internal.h``. + +If the new platform requires extra fields for any handle structure, create a +new include file in ``include/`` with the name ``uv-theplatform.h`` and add +the appropriate defines there. + +All functionality related to the new platform must be implemented in its own +file inside ``src/unix/`` unless it's already done in a common file, in which +case adding an `ifdef` is fine. + +Two build systems are supported: autotools and GYP. Ideally both need to be +supported, but if GYP does not support the new platform it can be left out. + +### Windows + +Windows is treated as a single platform, so adding support for a new platform +would mean adding support for a new version. + +Compilation and runtime must succeed for the minimum supported version. If a +new API is to be used, it must be done optionally, only in supported versions. + +### Common + +Some common notes when adding support for new platforms: + +* Generally libuv tries to avoid compile time checks. Do not add any to the + autotools based build system or use version checking macros. + Dynamically load functions and symbols if they are not supported by the + minimum supported version. diff --git a/3rd/libuv-1.19.2/android-configure b/3rd/libuv-1.19.2/android-configure new file mode 100644 index 00000000..b5c11cd4 --- /dev/null +++ b/3rd/libuv-1.19.2/android-configure @@ -0,0 +1,23 @@ +#!/bin/bash + +export TOOLCHAIN=$PWD/android-toolchain +mkdir -p $TOOLCHAIN +API=${3:-24} +$1/build/tools/make-standalone-toolchain.sh \ + --toolchain=arm-linux-androideabi-4.9 \ + --arch=arm \ + --install-dir=$TOOLCHAIN \ + --platform=android-$API \ + --force +export PATH=$TOOLCHAIN/bin:$PATH +export AR=arm-linux-androideabi-ar +export CC=arm-linux-androideabi-gcc +export CXX=arm-linux-androideabi-g++ +export LINK=arm-linux-androideabi-g++ +export PLATFORM=android +export CFLAGS="-D__ANDROID_API__=$API" + +if [[ $2 == 'gyp' ]] + then + ./gyp_uv.py -Dtarget_arch=arm -DOS=android -f make-android +fi diff --git a/3rd/libuv-1.19.2/appveyor.yml b/3rd/libuv-1.19.2/appveyor.yml new file mode 100644 index 00000000..1b018a59 --- /dev/null +++ b/3rd/libuv-1.19.2/appveyor.yml @@ -0,0 +1,32 @@ +version: v1.18.0.build{build} + +init: + - git config --global core.autocrlf true + +install: + - cinst -y nsis + +matrix: + fast_finish: true + allow_failures: + - platform: x86 + configuration: Release + - platform: x64 + configuration: Release + +platform: + - x86 + - x64 + +configuration: + - Release + +build_script: + # Fixed tag version number if using a tag. + - cmd: if "%APPVEYOR_REPO_TAG%" == "true" set APPVEYOR_BUILD_VERSION=%APPVEYOR_REPO_TAG_NAME% + # vcbuild overwrites the platform variable. + - cmd: set ARCH=%platform% + - cmd: vcbuild.bat release %ARCH% shared + +cache: + - C:\projects\libuv\build\gyp diff --git a/3rd/libuv-1.19.2/autogen.sh b/3rd/libuv-1.19.2/autogen.sh new file mode 100644 index 00000000..271c2ee8 --- /dev/null +++ b/3rd/libuv-1.19.2/autogen.sh @@ -0,0 +1,46 @@ +#!/bin/sh + +# 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's designed +around the event-driven asynchronous I/O model. + +The library provides much more than a simple 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. +- A TCP server handle that gets 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 matches, 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 duration calculated + in 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 ends 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: + + * File system operations + * DNS functions (getaddrinfo and getnameinfo) + * User specified code via :c:func:`uv_queue_work` + +.. warning:: + See the :c:ref:`threadpool` section for more details, but keep in mind the thread pool size + is quite limited. diff --git a/3rd/libuv-1.19.2/docs/src/dll.rst b/3rd/libuv-1.19.2/docs/src/dll.rst new file mode 100644 index 00000000..fb13f908 --- /dev/null +++ b/3rd/libuv-1.19.2/docs/src/dll.rst @@ -0,0 +1,44 @@ + +.. _dll: + +Shared library handling +======================= + +libuv provides cross platform utilities for loading shared libraries and +retrieving symbols from them, using the following API. + + +Data types +---------- + +.. c:type:: uv_lib_t + + Shared library data type. + + +Public members +^^^^^^^^^^^^^^ + +N/A + + +API +--- + +.. c:function:: int uv_dlopen(const char* filename, uv_lib_t* lib) + + Opens a shared library.

Its +core job is to provide an event loop and callback based notifications of I/O +and other activities. libuv offers core utilities like timers, non-blocking +networking support, asynchronous file system access, child processes and more. + +Event loops +----------- + +In event-driven programming, an application expresses interest in certain events +and respond to them when they occur. The responsibility of gathering events +from the operating system or monitoring other sources of events is handled by +libuv, and the user can register callbacks to be invoked when an event occurs. +The event-loop usually keeps running *forever*. In pseudocode: + +.. code-block:: python + + while there are still events to process: + e = get the next event + if there is a callback associated with e: + call the callback + +Some examples of events are: + +* File is ready for writing +* A socket has data ready to be read +* A timer has timed out + +This event loop is encapsulated by ``uv_run()`` -- the end-all function when using +libuv. + +The most common activity of systems programs is to deal with input and output, +rather than a lot of number-crunching. The problem with using conventional +input/output functions (``read``, ``fprintf``, etc.) is that they are +**blocking**. The actual write to a hard disk or reading from a network, takes +a disproportionately long time compared to the speed of the processor. The +functions don't return until the task is done, so that your program is doing +nothing. For programs which require high performance this is a major roadblock +as other activities and other I/O operations are kept waiting. + +One of the standard solutions is to use threads. Each blocking I/O operation is +started in a separate thread (or in a thread pool). When the blocking function +gets invoked in the thread, the processor can schedule another thread to run, +which actually needs the CPU. + +The approach followed by libuv uses another style, which is the **asynchronous, +non-blocking** style. Most modern operating systems provide event notification +subsystems. For example, a normal ``read`` call on a socket would block until +the sender actually sent something. Instead, the application can request the +operating system to watch the socket and put an event notification in the +queue. The application can inspect the events at its convenience (perhaps doing +some number crunching before to use the processor to the maximum) and grab the +data. It is **asynchronous** because the application expressed interest at one +point, then used the data at another point (in time and space). It is +**non-blocking** because the application process was free to do other tasks. +This fits in well with libuv's event-loop approach, since the operating system +events can be treated as just another libuv event. The non-blocking ensures +that other events can continue to be handled as fast as they come in [#]_. + +.. NOTE:: + + How the I/O is run in the background is not of our concern, but due to the + way our computer hardware works, with the thread as the basic unit of the + processor, libuv and OSes will usually run background/worker threads and/or + polling to perform tasks in a non-blocking manner. + +Bert Belder, one of the libuv core developers has a small video explaining the +architecture of libuv and its background. If you have no prior experience with +either libuv or libev, it is a quick, useful watch. + +libuv's event loop is explained in more detail in the `documentation +`_. + +.. raw:: html + + + +Hello World +----------- + +With the basics out of the way, lets write our first libuv program. It does +nothing, except start a loop which will exit immediately. + +.. rubric:: helloworld/main.c +.. literalinclude:: ../../code/helloworld/main.c + :linenos: + +This program quits immediately because it has no events to process. A libuv +event loop has to be told to watch out for events using the various API +functions. + +Starting with libuv v1.0, users should allocate the memory for the loops before +initializing it with ``uv_loop_init(uv_loop_t *)``. This allows you to plug in +custom memory management. Remember to de-initialize the loop using +``uv_loop_close(uv_loop_t *)`` and then delete the storage. The examples never +close loops since the program quits after the loop ends and the system will +reclaim memory. Production grade projects, especially long running systems +programs, should take care to release correctly. + +Default loop +++++++++++++ + +A default loop is provided by libuv and can be accessed using +``uv_default_loop()``. You should use this loop if you only want a single +loop. + +.. note:: + + node.js uses the default loop as its main loop. If you are writing bindings + you should be aware of this. + +.. _libuv-error-handling: + +Error handling +-------------- + +Initialization functions or synchronous functions which may fail return a negative number on error. Async functions that may fail will pass a status parameter to their callbacks. The error messages are defined as ``UV_E*`` `constants`_. + +.. _constants: http://docs.libuv.org/en/v1.x/errors.html#error-constants + +You can use the ``uv_strerror(int)`` and ``uv_err_name(int)`` functions +to get a ``const char *`` describing the error or the error name respectively. + +I/O read callbacks (such as for files and sockets) are passed a parameter ``nread``. If ``nread`` is less than 0, there was an error (UV_EOF is the end of file error, which you may want to handle differently). + +Handles and Requests +-------------------- + +libuv works by the user expressing interest in particular events. This is +usually done by creating a **handle** to an I/O device, timer or process. +Handles are opaque structs named as ``uv_TYPE_t`` where type signifies what the +handle is used for. + +.. rubric:: libuv watchers +.. literalinclude:: ../../../include/uv.h + :lines: 197-230 + +Handles represent long-lived objects. Async operations on such handles are +identified using **requests**. A request is short-lived (usually used across +only one callback) and usually indicates one I/O operation on a handle. +Requests are used to preserve context between the initiation and the callback +of individual actions. For example, an UDP socket is represented by +a ``uv_udp_t``, while individual writes to the socket use a ``uv_udp_send_t`` +structure that is passed to the callback after the write is done. + +Handles are setup by a corresponding:: + + uv_TYPE_init(uv_loop_t *, uv_TYPE_t *) + +function. + +Callbacks are functions which are called by libuv whenever an event the watcher +is interested in has taken place. Application specific logic will usually be +implemented in the callback. For example, an IO watcher's callback will receive +the data read from a file, a timer callback will be triggered on timeout and so +on. + +Idling +++++++ + +Here is an example of using an idle handle. The callback is called once on +every turn of the event loop. A use case for idle handles is discussed in +:doc:`utilities`. Let us use an idle watcher to look at the watcher life cycle +and see how ``uv_run()`` will now block because a watcher is present. The idle +watcher is stopped when the count is reached and ``uv_run()`` exits since no +event watchers are active. + +.. rubric:: idle-basic/main.c +.. literalinclude:: ../../code/idle-basic/main.c + :emphasize-lines: 6,10,14-17 + +Storing context ++++++++++++++++ + +In callback based programming style you'll often want to pass some 'context' -- +application specific information -- between the call site and the callback. All +handles and requests have a ``void* data`` member which you can set to the +context and cast back in the callback. This is a common pattern used throughout +the C library ecosystem. In addition ``uv_loop_t`` also has a similar data +member. + +---- + +..

Use ``uv_unref()`` if you want to be more *fire-and-forget*. + +Sending signals to processes +---------------------------- + +libuv wraps the standard ``kill(2)`` system call on Unix and implements one +with similar semantics on Windows, with *one caveat*: all of ``SIGTERM``, +``SIGINT`` and ``SIGKILL``, lead to termination of the process. The signature +of ``uv_kill`` is:: + + uv_err_t uv_kill(int pid, int signum); + +For processes started using libuv, you may use ``uv_process_kill`` instead, +which accepts the ``uv_process_t`` watcher as the first argument, rather than +the pid. In this case, **remember to call** ``uv_close`` on the watcher. + +Signals +------- + +libuv provides wrappers around Unix signals with `some Windows support +`_ as well. + +Use ``uv_signal_init()`` to initialize +a handle and associate it with a loop. To listen for particular signals on +that handler, use ``uv_signal_start()`` with the handler function. Each handler +can only be associated with one signal number, with subsequent calls to +``uv_signal_start()`` overwriting earlier associations. Use ``uv_signal_stop()`` to +stop watching. Here is a small example demonstrating the various possibilities: + +.. rubric:: signal/main.c +.. literalinclude:: ../../code/signal/main.c + :linenos: + :emphasize-lines: 17-18,27-28 + +.. NOTE:: + + ``uv_run(loop, UV_RUN_NOWAIT)`` is similar to ``uv_run(loop, UV_RUN_ONCE)`` + in that it will process only one event. UV_RUN_ONCE blocks if there are no + pending events, while UV_RUN_NOWAIT will return immediately. We use NOWAIT + so that one of the loops isn't starved because the other one has no pending + activity. + +Send ``SIGUSR1`` to the process, and you'll find the handler being invoked +4 times, one for each ``uv_signal_t``. The handler just stops each handle, +so that the program exits. This sort of dispatch to all handlers is very +useful. A server using multiple event loops could ensure that all data was +safely saved before termination, simply by every loop adding a watcher for +``SIGINT``. + +Child Process I/O +----------------- + +A normal, newly spawned process has its own set of file descriptors, with 0, +1 and 2 being ``stdin``, ``stdout`` and ``stderr`` respectively. Sometimes you +may want to share file descriptors with the child. For example, perhaps your +applications launches a sub-command and you want any errors to go in the log +file, but ignore ``stdout``. For this you'd like to have ``stderr`` of the +child be the same as the stderr of the parent. In this case, libuv supports +*inheriting* file descriptors. In this sample, we invoke the test program, +which is: + +.. rubric:: proc-streams/test.c +.. literalinclude:: ../../code/proc-streams/test.c + +The actual program ``proc-streams`` runs this while sharing only ``stderr``. +The file descriptors of the child process are set using the ``stdio`` field in +``uv_process_options_t``.

Use ``UV_IGNORE`` if it isn't going to be +used. If the first three ``stdio`` fields are marked as ``UV_IGNORE`` they'll +redirect to ``/dev/null``. + +Since we want to pass on an existing descriptor, we'll use ``UV_INHERIT_FD``. +Then we set the ``fd`` to ``stderr``. + +.. rubric:: proc-streams/main.c +.. literalinclude:: ../../code/proc-streams/main.c + :linenos: + :lines: 15-17,27- + :emphasize-lines: 6,10,11,12 + +If you run ``proc-stream`` you'll see that only the line "This is stderr" will +be displayed.

By setting ``flags`` +to ``UV_INHERIT_STREAM`` and setting ``data.stream`` to the stream in the +parent process, the child process can treat that stream as standard I/O. This +can be used to implement something like CGI_. + +.. _CGI: http://en.wikipedia.org/wiki/Common_Gateway_Interface + +A sample CGI script/executable is: + +.. rubric:: cgi/tick.c +.. literalinclude:: ../../code/cgi/tick.c + +The CGI server combines the concepts from this chapter and :doc:`networking` so +that every client is sent ten ticks after which that connection is closed. + +.. rubric:: cgi/main.c +.. literalinclude:: ../../code/cgi/main.c + :linenos: + :lines: 49-63 + :emphasize-lines: 10 + +Here we simply accept the TCP connection and pass on the socket (*stream*) to +``invoke_cgi_script``. + +.. rubric:: cgi/main.c +.. literalinclude:: ../../code/cgi/main.c + :linenos: + :lines: 16, 25-45 + :emphasize-lines: 8-9,18,20 + +The ``stdout`` of the CGI script is set to the socket so that whatever our tick +script prints, gets sent to the client.

The MySQL server also runs a domain socket on +which clients can interact with it. + +.. _D-BUS: http://www.freedesktop.org/wiki/Software/dbus + +When using domain sockets, a client-server pattern is usually followed with the +creator/owner of the socket acting as the server.

You can test this server using `socat`_:: + + $ socat - /path/to/socket + +A client which wants to connect to a domain socket will use:: + + void uv_pipe_connect(uv_connect_t *req, uv_pipe_t *handle, const char *name, uv_connect_cb cb); + +where ``name`` will be ``echo.sock`` or similar. + +.. _socat: http://www.dest-unreach.org/socat/ + +Sending file descriptors over pipes ++++++++++++++++++++++++++++++++++++ + +The cool thing about domain sockets is that file descriptors can be exchanged +between processes by sending them over a domain socket. This allows processes +to hand off their I/O to other processes. Applications include load-balancing +servers, worker processes and other ways to make optimum use of CPU. libuv only +supports sending **TCP sockets or other pipes** over pipes for now. + +To demonstrate, we will look at a echo server implementation that hands of +clients to worker processes in a round-robin fashion.

It is important to set the ``ipc`` +argument of ``uv_pipe_init`` to 1 to indicate this pipe will be used for +inter-process communication! Since the master will write the file handle to the +standard input of the worker, we connect the pipe to ``stdin`` using +``uv_pipe_open``. + +.. rubric:: multi-echo-server/worker.c +.. literalinclude:: ../../code/multi-echo-server/worker.c + :linenos: + :lines: 51-79 + :emphasize-lines: 10,15,20 + +First we call ``uv_pipe_pending_count()`` to ensure that a handle is available +to read out. If your program could deal with different types of handles, +``uv_pipe_pending_type()`` can be used to determine the type. +Although ``accept`` seems odd in this code, it actually makes sense. What +``accept`` traditionally does is get a file descriptor (the client) from +another file descriptor (The listening socket). Which is exactly what we do +here. Fetch the file descriptor (``client``) from ``queue``. From this point +the worker does standard echo server stuff. + +Turning now to the master, let's take a look at how the workers are launched to +allow load balancing. + +.. rubric:: multi-echo-server/main.c +.. literalinclude:: ../../code/multi-echo-server/main.c + :linenos: + :lines: 9-13 + +The ``child_worker`` structure wraps the process, and the pipe between the +master and the individual process. + +.. rubric:: multi-echo-server/main.c +.. literalinclude:: ../../code/multi-echo-server/main.c + :linenos: + :lines: 51,61-95 + :emphasize-lines: 17,20-21 + +In setting up the workers, we use the nifty libuv function ``uv_cpu_info`` to +get the number of CPUs so we can launch an equal number of workers.

We then indicate that the child process' ``stdin`` is to be +a readable pipe (from the point of view of the child). Everything is +straightforward till here. The workers are launched and waiting for file +descriptors to be written to their standard input. + +It is in ``on_new_connection`` (the TCP infrastructure is initialized in +``main()``), that we accept the client socket and pass it along to the next +worker in the round-robin. + +.. rubric:: multi-echo-server/main.c +.. literalinclude:: ../../code/multi-echo-server/main.c + :linenos: + :lines: 31-49 + :emphasize-lines: 9,12-13 + +The ``uv_write2`` call handles all the abstraction and it is simply a matter of +passing in the handle (``client``) as the right argument.

Threads are therefore mighty useful sometimes, even +though you might have to wade through various synchronization primitives. + +Threads are used internally to fake the asynchronous nature of all of the system +calls. libuv also uses threads to allow you, the application, to perform a task +asynchronously that is actually blocking, by spawning a thread and collecting +the result when it is done. + +Today there are two predominant thread libraries: the Windows threads +implementation and POSIX's `pthreads`_. libuv's thread API is analogous to +the pthreads API and often has similar semantics. + +A notable aspect of libuv's thread facilities is that it is a self contained +section within libuv.

If a task has *already started +executing, or it has finished executing*, ``uv_cancel()`` **will fail**. + +``uv_cancel()`` is useful to cleanup pending tasks if the user requests +termination. For example, a music player may queue up multiple directories to +be scanned for audio files. If the user terminates the program, it should quit +quickly and not wait until all pending requests are run. + +Let's modify the fibonacci example to demonstrate ``uv_cancel()``. We first set +up a signal handler for termination. + +.. rubric:: queue-cancel/main.c +.. literalinclude:: ../../code/queue-cancel/main.c + :linenos: + :lines: 43- + +When the user triggers the signal by pressing ``Ctrl+C`` we send +``uv_cancel()`` to all the workers. ``uv_cancel()`` will return ``0`` for those that are already executing or finished. + +.. rubric:: queue-cancel/main.c +.. literalinclude:: ../../code/queue-cancel/main.c + :linenos: + :lines: 33-41 + :emphasize-lines: 6 + +For tasks that do get cancelled successfully, the *after* function is called +with ``status`` set to ``UV_ECANCELED``. + +.. rubric:: queue-cancel/main.c +.. literalinclude:: ../../code/queue-cancel/main.c + :linenos: + :lines: 28-31 + :emphasize-lines: 2 + +``uv_cancel()`` can also be used with ``uv_fs_t`` and ``uv_getaddrinfo_t`` +requests.

TIP:: + + A well designed program would have a way to terminate long running workers + that have already started executing. Such a worker could periodically check + for a variable that only the main process sets to signal termination. + +.. _inter-thread-communication: + +Inter-thread communication +-------------------------- + +Sometimes you want various threads to actually send each other messages *while* +they are running. For example you might be running some long duration task in +a separate thread (perhaps using ``uv_queue_work``) but want to notify progress +to the main thread. This is a simple example of having a download manager +informing the user of the status of running downloads. + +.. rubric:: progress/main.c +.. literalinclude:: ../../code/progress/main.c + :linenos: + :lines: 7-8,34- + :emphasize-lines: 2,11 + +The async thread communication works *on loops* so although any thread can be +the message sender, only threads with libuv loops can be receivers (or rather +the loop is the receiver). libuv will invoke the callback (``print_progress``) +with the async watcher whenever it receives a message. + +.. warning:: + + It is important to realize that since the message send is *async*, the callback + may be invoked immediately after ``uv_async_send`` is called in another + thread, or it may be invoked after some time. libuv may also combine + multiple calls to ``uv_async_send`` and invoke your callback only once. The + only guarantee that libuv makes is -- The callback function is called *at + least once* after the call to ``uv_async_send``. If you have no pending + calls to ``uv_async_send``, the callback won't be called. If you make two + or more calls, and libuv hasn't had a chance to run the callback yet, it + *may* invoke your callback *only once* for the multiple invocations of + ``uv_async_send``. Your callback will never be called twice for just one + event. + +.. rubric:: progress/main.c +.. literalinclude:: ../../code/progress/main.c + :linenos: + :lines: 10-23 + :emphasize-lines: 7-8 + +In the download function, we modify the progress indicator and queue the message +for delivery with ``uv_async_send``.

Use +a mutex or rwlock to ensure accesses are performed in the right order. + +.. note:: + + mutexes and rwlocks **DO NOT** work inside a signal handler, whereas + ``uv_async_send`` does. + +One use case where ``uv_async_send`` is required is when interoperating with +libraries that require thread affinity for their functionality. For example in +node.js, a v8 engine instance, contexts and its objects are bound to the thread +that the v8 instance was started in. Interacting with v8 data structures from +another thread can lead to undefined results. Now consider some node.js module +which binds a third party library. It may go something like this: + +1. In node, the third party library is set up with a JavaScript callback to be + invoked for more information:: + + var lib = require('lib'); + lib.on_progress(function() { + console.log("Progress"); + }); + + lib.do(); + + // do other stuff + +2. ``lib.do`` is supposed to be non-blocking but the third party lib is + blocking, so the binding uses ``uv_queue_work``. + +3. The actual work being done in a separate thread wants to invoke the progress + callback, but cannot directly call into v8 to interact with JavaScript. So + it uses ``uv_async_send``. + +4. The async callback, invoked in the main loop thread, which is the v8 thread, + then interacts with v8 to invoke the JavaScript callback. + +.. _pthreads: http://man7.org/linux/man-pages/man7/pthreads.7.html + +---- + +.. _node.js is cancer: http://teddziuba.github.io/2011/10/node-js-is-cancer.html +.. _bnoordhuis: https://github.com/bnoordhuis diff --git a/3rd/libuv-1.19.2/docs/src/guide/utilities.rst b/3rd/libuv-1.19.2/docs/src/guide/utilities.rst new file mode 100644 index 00000000..abe6fa8d --- /dev/null +++ b/3rd/libuv-1.19.2/docs/src/guide/utilities.rst @@ -0,0 +1,433 @@ +Utilities +========= + +This chapter catalogues tools and techniques which are useful for common tasks. +The `libev man page`_ already covers some patterns which can be adopted to +libuv through simple API changes. It also covers parts of the libuv API that +don't require entire chapters dedicated to them. + +Timers +------ + +Timers invoke the callback after a certain time has elapsed since the timer was +started. libuv timers can also be set to invoke at regular intervals instead of +just once. + +Simple use is to init a watcher and start it with a ``timeout``, and optional ``repeat``. +Timers can be stopped at any time. + +.. code-block:: c + + uv_timer_t timer_req; + + uv_timer_init(loop, &timer_req); + uv_timer_start(&timer_req, callback, 5000, 2000); + +will start a repeating timer, which first starts 5 seconds (the ``timeout``) after the execution +of ``uv_timer_start``, then repeats every 2 seconds (the ``repeat``). Use: + +.. code-block:: c + + uv_timer_stop(&timer_req); + +to stop the timer. This can be used safely from within the callback as well. + +The repeat interval can be modified at any time with:: + + uv_timer_set_repeat(uv_timer_t *timer, int64_t repeat); + +which will take effect **when possible**. If this function is called from +a timer callback, it means: + +* If the timer was non-repeating, the timer has already been stopped. Use + ``uv_timer_start`` again. +* If the timer is repeating, the next timeout has already been scheduled, so + the old repeat interval will be used once more before the timer switches to + the new interval. + +The utility function:: + + int uv_timer_again(uv_timer_t *) + +applies **only to repeating timers** and is equivalent to stopping the timer +and then starting it with both initial ``timeout`` and ``repeat`` set to the +old ``repeat`` value. If the timer hasn't been started it fails (error code +``UV_EINVAL``) and returns -1. + +An actual timer example is in the :ref:`reference count section +`. + +.. _reference-count: + +Event loop reference count +-------------------------- + +The event loop only runs as long as there are active handles. This system +works by having every handle increase the reference count of the event loop +when it is started and decreasing the reference count when stopped. It is also +possible to manually change the reference count of handles using:: + + void uv_ref(uv_handle_t*); + void uv_unref(uv_handle_t*); + +These functions can be used to allow a loop to exit even when a watcher is +active or to use custom objects to keep the loop alive. + +The latter can be used with interval timers. You might have a garbage collector +which runs every X seconds, or your network service might send a heartbeat to +others periodically, but you don't want to have to stop them along all clean +exit paths or error scenarios. Or you want the program to exit when all your +other watchers are done. In that case just unref the timer immediately after +creation so that if it is the only watcher running then ``uv_run`` will still +exit. + +This is also used in node.js where some libuv methods are being bubbled up to +the JS API.

The idle +callback can be used to perform some very low priority activity. For example, +you could dispatch a summary of the daily application performance to the +developers for analysis during periods of idleness, or use the application's +CPU time to perform SETI calculations :) An idle watcher is also useful in +a GUI application. Say you are using an event loop for a file download.

The solution is to use a ``struct`` and set +``uv_work_t.data`` to point to it. A slight variation is to have the +``uv_work_t`` itself as the first member of this struct (called a baton [#]_). +This allows cleaning up the work request and all the data in one free call. + +.. code-block:: c + :linenos: + :emphasize-lines: 2 + + struct ftp_baton { + uv_work_t req; + char *host; + int port; + char *username; + char *password; + } + +.. code-block:: c + :linenos: + :emphasize-lines: 2 + + ftp_baton *baton = (ftp_baton*) malloc(sizeof(ftp_baton)); + baton->req.data = (void*) baton; + baton->host = strdup("my.webhost.com"); + baton->port = 21; + // ... + + uv_queue_work(loop, &baton->req, ftp_session, ftp_cleanup); + +Here we create the baton and queue the task. + +Now the task function can extract the data it needs: + +.. code-block:: c + :linenos: + :emphasize-lines: 2, 12 + + void ftp_session(uv_work_t *req) { + ftp_baton *baton = (ftp_baton*) req->data; + + fprintf(stderr, "Connecting to %s\n", baton->host); + } + + void ftp_cleanup(uv_work_t *req) { + ftp_baton *baton = (ftp_baton*) req->data; + + free(baton->host); + // ... + free(baton); + } + +We then free the baton which also frees the watcher. + +External I/O with polling +------------------------- + +Usually third-party libraries will handle their own I/O, and keep track of +their sockets and other files internally. In this case it isn't possible to use +the standard stream I/O operations, but the library can still be integrated +into the libuv event loop. All that is required is that the library allow you +to access the underlying file descriptors and provide functions that process +tasks in small increments as decided by your application. Some libraries though +will not allow such access, providing only a standard blocking function which +will perform the entire I/O transaction and only then return. It is unwise to +use these in the event loop thread, use the :ref:`libuv-work-queue` instead. Of +course, this will also mean losing granular control on the library. + +The ``uv_poll`` section of libuv simply watches file descriptors using the +operating system notification mechanism. In some sense, all the I/O operations +that libuv implements itself are also backed by ``uv_poll`` like code. Whenever +the OS notices a change of state in file descriptors being polled, libuv will +invoke the associated callback. + +Here we will walk through a simple download manager that will use libcurl_ to +download files. Rather than give all control to libcurl, we'll instead be +using the libuv event loop, and use the non-blocking, async multi_ interface to +progress with the download whenever libuv notifies of I/O readiness. + +.. _libcurl: http://curl.haxx.se/libcurl/ +.. _multi: http://curl.haxx.se/libcurl/c/libcurl-multi.html + +.. rubric:: uvwget/main.c - The setup +.. literalinclude:: ../../code/uvwget/main.c + :linenos: + :lines: 1-9,140- + :emphasize-lines: 7,21,24-25 + +The way each library is integrated with libuv will vary. In the case of +libcurl, we can register two callbacks. The socket callback ``handle_socket`` +is invoked whenever the state of a socket changes and we have to start polling +it. ``start_timeout`` is called by libcurl to notify us of the next timeout +interval, after which we should drive libcurl forward regardless of I/O status. +This is so that libcurl can handle errors or do whatever else is required to +get the download moving. + +Our downloader is to be invoked as:: + + $ ./uvwget [url1] [url2] ... + +So we add each argument as an URL + +.. rubric:: uvwget/main.c - Adding urls +.. literalinclude:: ../../code/uvwget/main.c + :linenos: + :lines: 39-56 + :emphasize-lines: 13-14 + +We let libcurl directly write the data to a file, but much more is possible if +you so desire. + +``start_timeout`` will be called immediately the first time by libcurl, so +things are set in motion. This simply starts a libuv `timer `_ which +drives ``curl_multi_socket_action`` with ``CURL_SOCKET_TIMEOUT`` whenever it +times out. ``curl_multi_socket_action`` is what drives libcurl, and what we +call whenever sockets change state. But before we go into that, we need to poll +on sockets whenever ``handle_socket`` is called. + +.. rubric:: uvwget/main.c - Setting up polling +.. literalinclude:: ../../code/uvwget/main.c + :linenos: + :lines: 102-140 + :emphasize-lines: 9,11,15,21,24 + +We are interested in the socket fd ``s``, and the ``action``. For every socket +we create a ``uv_poll_t`` handle if it doesn't exist, and associate it with the +socket using ``curl_multi_assign``. This way ``socketp`` points to it whenever +the callback is invoked. + +In the case that the download is done or fails, libcurl requests removal of the +poll. So we stop and free the poll handle. + +Depending on what events libcurl wishes to watch for, we start polling with +``UV_READABLE`` or ``UV_WRITABLE``. Now libuv will invoke the poll callback +whenever the socket is ready for reading or writing. Calling ``uv_poll_start`` +multiple times on the same handle is acceptable, it will just update the events +mask with the new value. ``curl_perform`` is the crux of this program. + +.. rubric:: uvwget/main.c - Driving libcurl. +.. literalinclude:: ../../code/uvwget/main.c + :linenos: + :lines: 81-95 + :emphasize-lines: 2,6-7,12 + +The first thing we do is to stop the timer, since there has been some progress +in the interval. Then depending on what event triggered the callback, we set +the correct flags. Then we call ``curl_multi_socket_action`` with the socket +that progressed and the flags informing about what events happened. At this +point libcurl does all of its internal tasks in small increments, and will +attempt to return as fast as possible, which is exactly what an evented program +wants in its main thread. libcurl keeps queueing messages into its own queue +about transfer progress. In our case we are only interested in transfers that +are completed.

The usage is +quite simple as long as your library exports the right symbols. Be careful with +sanity and security checks when loading third party code, otherwise your +program will behave unpredictably. This example implements a very simple +plugin system which does nothing except print the name of the plugin. + +Let us first look at the interface provided to plugin authors. + +.. rubric:: plugin/plugin.h +.. literalinclude:: ../../code/plugin/plugin.h + :linenos: + +You can similarly add more functions that plugin authors can use to do useful +things in your application [#]_. A sample plugin using this API is: + +.. rubric:: plugin/hello.c +.. literalinclude:: ../../code/plugin/hello.c + :linenos: + +Our interface defines that all plugins should have an ``initialize`` function +which will be called by the application. This plugin is compiled as a shared +library and can be loaded by running our application:: + + $ ./plugin libhello.dylib + Loading libhello.dylib + Registered plugin "Hello World!" + +.. NOTE:: + + The shared library filename will be different depending on platforms. On + Linux it is ``libhello.so``. + +This is done by using ``uv_dlopen`` to first load the shared library +``libhello.dylib``. Then we get access to the ``initialize`` function using +``uv_dlsym`` and invoke it. + +.. rubric:: plugin/main.c +.. literalinclude:: ../../code/plugin/main.c + :linenos: + :lines: 7- + :emphasize-lines: 15, 18, 24 + +``uv_dlopen`` expects a path to the shared library and sets the opaque +``uv_lib_t`` pointer. It returns 0 on success, -1 on error. Use ``uv_dlerror`` +to get the error message. + +``uv_dlsym`` stores a pointer to the symbol in the second argument in the third +argument. ``init_plugin_function`` is a function pointer to the sort of +function we are looking for in the application's plugins. + +.. _shared libraries: http://en.wikipedia.org/wiki/Shared_library#Shared_libraries + +TTY +--- + +Text terminals have supported basic formatting for a long time, with a `pretty +standardised`_ command set. This formatting is often used by programs to +improve the readability of terminal output. For example ``grep --colour``. +libuv provides the ``uv_tty_t`` abstraction (a stream) and related functions to +implement the ANSI escape codes across all platforms. By this I mean that libuv +converts ANSI codes to the Windows equivalent, and provides functions to get +terminal information. + +.. _pretty standardised: http://en.wikipedia.org/wiki/ANSI_escape_sequences + +The first thing to do is to initialize a ``uv_tty_t`` with the file descriptor +it reads/writes from. This is achieved with:: + + int uv_tty_init(uv_loop_t*, uv_tty_t*, uv_file fd, int readable) + +Set ``readable`` to true if you plan to use ``uv_read_start()`` on the stream. + +It is then best to use ``uv_tty_set_mode`` to set the mode to *normal* +which enables most TTY formatting, flow-control and other settings. Other_ modes +are also available. + +.. _Other: http://docs.libuv.org/en/v1.x/tty.html#c.uv_tty_mode_t + +Remember to call ``uv_tty_reset_mode`` when your program exits to restore the +state of the terminal. Just good manners. Another set of good manners is to be +aware of redirection. If the user redirects the output of your command to +a file, control sequences should not be written as they impede readability and +``grep``. To check if the file descriptor is indeed a TTY, call +``uv_guess_handle`` with the file descriptor and compare the return value with +``UV_TTY``. + +Here is a simple example which prints white text on a red background: + +.. rubric:: tty/main.c +.. literalinclude:: ../../code/tty/main.c + :linenos: + :emphasize-lines: 11-12,14,17,27 + +The final TTY helper is ``uv_tty_get_winsize()`` which is used to get the +width and height of the terminal and returns ``0`` on success.

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.

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][] 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. Each new test needs to be registered in `test/test-list.h`. If you add a new test file, it needs to be registered in two places: -- `Makefile.am`: add the file's name to the `test_run_tests_SOURCES` list. -- `uv.gyp`: add the file's name to the `sources` list in the `run-tests` target. - -Look at other tests to see how they should be structured (license boilerplate, -the way entry points are declared, etc.). - -Check README.md file to find out how to run the test suite and make sure that -there are no test regressions. - -### PUSH - -``` -$ git push origin my-feature-branch -``` - -Go to https://github.com/username/libuv and select your feature branch. Click -the 'Pull Request' button and fill out the form. - -Pull requests are usually reviewed within a few days. If there are comments -to address, apply your changes in a separate commit and push that to your -feature branch. Post a comment in the pull request afterwards; GitHub does -not send out notifications when you add commits. - - -[issue tracker]: https://github.com/libuv/libuv/issues -[libuv mailing list]: http://groups.google.com/group/libuv -[IRC]: http://webchat.freenode.net/?channels=libuv -[Google C/C++ style guide]: https://google.github.io/styleguide/cppguide.html -[project maintainers]: https://github.com/libuv/libuv/blob/master/MAINTAINERS.md diff --git a/3rd/libuv-1.19.2/ChangeLog b/3rd/libuv-1.19.2/ChangeLog deleted file mode 100644 index 53ebd01d..00000000 --- a/3rd/libuv-1.19.2/ChangeLog +++ /dev/null @@ -1,3531 +0,0 @@ -2018.02.22, Version 1.19.2 (Stable) -

It's designed -around the event-driven asynchronous I/O model. - -The library provides much more than a simple 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. -- A TCP server handle that gets 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 matches, 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 duration calculated - in 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 ends 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: - - * File system operations - * DNS functions (getaddrinfo and getnameinfo) - * User specified code via :c:func:`uv_queue_work` - -.. warning:: - See the :c:ref:`threadpool` section for more details, but keep in mind the thread pool size - is quite limited. diff --git a/3rd/libuv-1.19.2/docs/src/dll.rst b/3rd/libuv-1.19.2/docs/src/dll.rst deleted file mode 100644 index fb13f908..00000000 --- a/3rd/libuv-1.19.2/docs/src/dll.rst +++ /dev/null @@ -1,44 +0,0 @@ - -.. _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.

Its -core job is to provide an event loop and callback based notifications of I/O -and other activities. libuv offers core utilities like timers, non-blocking -networking support, asynchronous file system access, child processes and more. - -Event loops ------------ - -In event-driven programming, an application expresses interest in certain events -and respond to them when they occur. The responsibility of gathering events -from the operating system or monitoring other sources of events is handled by -libuv, and the user can register callbacks to be invoked when an event occurs. -The event-loop usually keeps running *forever*. In pseudocode: - -.. code-block:: python - - while there are still events to process: - e = get the next event - if there is a callback associated with e: - call the callback - -Some examples of events are: - -* File is ready for writing -* A socket has data ready to be read -* A timer has timed out - -This event loop is encapsulated by ``uv_run()`` -- the end-all function when using -libuv. - -The most common activity of systems programs is to deal with input and output, -rather than a lot of number-crunching. The problem with using conventional -input/output functions (``read``, ``fprintf``, etc.) is that they are -**blocking**. The actual write to a hard disk or reading from a network, takes -a disproportionately long time compared to the speed of the processor. The -functions don't return until the task is done, so that your program is doing -nothing. For programs which require high performance this is a major roadblock -as other activities and other I/O operations are kept waiting. - -One of the standard solutions is to use threads. Each blocking I/O operation is -started in a separate thread (or in a thread pool). When the blocking function -gets invoked in the thread, the processor can schedule another thread to run, -which actually needs the CPU. - -The approach followed by libuv uses another style, which is the **asynchronous, -non-blocking** style. Most modern operating systems provide event notification -subsystems. For example, a normal ``read`` call on a socket would block until -the sender actually sent something. Instead, the application can request the -operating system to watch the socket and put an event notification in the -queue. The application can inspect the events at its convenience (perhaps doing -some number crunching before to use the processor to the maximum) and grab the -data. It is **asynchronous** because the application expressed interest at one -point, then used the data at another point (in time and space). It is -**non-blocking** because the application process was free to do other tasks. -This fits in well with libuv's event-loop approach, since the operating system -events can be treated as just another libuv event. The non-blocking ensures -that other events can continue to be handled as fast as they come in [#]_. - -.. NOTE:: - - How the I/O is run in the background is not of our concern, but due to the - way our computer hardware works, with the thread as the basic unit of the - processor, libuv and OSes will usually run background/worker threads and/or - polling to perform tasks in a non-blocking manner. - -Bert Belder, one of the libuv core developers has a small video explaining the -architecture of libuv and its background.

A libuv -event loop has to be told to watch out for events using the various API -functions. - -Starting with libuv v1.0, users should allocate the memory for the loops before -initializing it with ``uv_loop_init(uv_loop_t *)``. This allows you to plug in -custom memory management. Remember to de-initialize the loop using -``uv_loop_close(uv_loop_t *)`` and then delete the storage. The examples never -close loops since the program quits after the loop ends and the system will -reclaim memory. Production grade projects, especially long running systems -programs, should take care to release correctly. - -Default loop -++++++++++++ - -A default loop is provided by libuv and can be accessed using -``uv_default_loop()``. You should use this loop if you only want a single -loop. - -.. note:: - - node.js uses the default loop as its main loop. If you are writing bindings - you should be aware of this. - -.. _libuv-error-handling: - -Error handling --------------- - -Initialization functions or synchronous functions which may fail return a negative number on error. Async functions that may fail will pass a status parameter to their callbacks. The error messages are defined as ``UV_E*`` `constants`_. - -.. _constants: http://docs.libuv.org/en/v1.x/errors.html#error-constants - -You can use the ``uv_strerror(int)`` and ``uv_err_name(int)`` functions -to get a ``const char *`` describing the error or the error name respectively. - -I/O read callbacks (such as for files and sockets) are passed a parameter ``nread``. If ``nread`` is less than 0, there was an error (UV_EOF is the end of file error, which you may want to handle differently). - -Handles and Requests --------------------- - -libuv works by the user expressing interest in particular events. This is -usually done by creating a **handle** to an I/O device, timer or process. -Handles are opaque structs named as ``uv_TYPE_t`` where type signifies what the -handle is used for. - -.. rubric:: libuv watchers -.. literalinclude:: ../../../include/uv.h - :lines: 197-230 - -Handles represent long-lived objects.

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][] 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. Each new test needs to be registered in `test/test-list.h`. If you add a new test file, it needs to be registered in two places: +- `Makefile.am`: add the file's name to the `test_run_tests_SOURCES` list. +- `uv.gyp`: add the file's name to the `sources` list in the `run-tests` target. + +Look at other tests to see how they should be structured (license boilerplate, +the way entry points are declared, etc.). + +Check README.md file to find out how to run the test suite and make sure that +there are no test regressions. + +### PUSH + +``` +$ git push origin my-feature-branch +``` + +Go to https://github.com/username/libuv and select your feature branch. Click +the 'Pull Request' button and fill out the form. + +Pull requests are usually reviewed within a few days. If there are comments +to address, apply your changes in a separate commit and push that to your +feature branch. Post a comment in the pull request afterwards; GitHub does +not send out notifications when you add commits. + + +[issue tracker]: https://github.com/libuv/libuv/issues +[libuv mailing list]:

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: + +```bash +$ gpg --keyserver pool.sks-keyservers.net --recv-keys AE9BC059 +``` + +Importing a key from a git blob object: + +```bash +$ git show pubkey-saghul | gpg --import +``` + +### Verifying releases + +Git tags are signed with the developer's key, they can be verified as follows: + +```bash +$ 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: + +```bash +$ 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: + +```bash +$ sh autogen.sh +$ ./configure +$ make +$ make check +$ make install +``` + +### Windows + +Prerequisites: + +* [Python 2.6 or 2.7][] as it is required + by [GYP][]. + If python is not in your path, set the environment variable `PYTHON` to its + location.

The new platform +will need to implement some of the functions, the prototypes are in +``src/unix/internal.h``. + +If the new platform requires extra fields for any handle structure, create a +new include file in ``include/`` with the name ``uv-theplatform.h`` and add +the appropriate defines there. + +All functionality related to the new platform must be implemented in its own +file inside ``src/unix/`` unless it's already done in a common file, in which +case adding an `ifdef` is fine. + +Two build systems are supported: autotools and GYP. Ideally both need to be +supported, but if GYP does not support the new platform it can be left out. + +### Windows + +Windows is treated as a single platform, so adding support for a new platform +would mean adding support for a new version. + +Compilation and runtime must succeed for the minimum supported version. If a +new API is to be used, it must be done optionally, only in supported versions. + +### Common + +Some common notes when adding support for new platforms: + +* Generally libuv tries to avoid compile time checks. Do not add any to the + autotools based build system or use version checking macros. + Dynamically load functions and symbols if they are not supported by the + minimum supported version. diff --git a/3rd/libuv-1.19.2/android-configure b/3rd/libuv-1.19.2/android-configure new file mode 100644 index 00000000..b5c11cd4 --- /dev/null +++ b/3rd/libuv-1.19.2/android-configure @@ -0,0 +1,23 @@ +#!/bin/bash + +export TOOLCHAIN=$PWD/android-toolchain +mkdir -p $TOOLCHAIN +API=${3:-24} +$1/build/tools/make-standalone-toolchain.sh \ + --toolchain=arm-linux-androideabi-4.9 \ + --arch=arm \ + --install-dir=$TOOLCHAIN \ + --platform=android-$API \ + --force +export PATH=$TOOLCHAIN/bin:$PATH +export AR=arm-linux-androideabi-ar +export CC=arm-linux-androideabi-gcc +export CXX=arm-linux-androideabi-g++ +export LINK=arm-linux-androideabi-g++ +export PLATFORM=android +export CFLAGS="-D__ANDROID_API__=$API" + +if [[ $2 == 'gyp' ]] + then + ./gyp_uv.py -Dtarget_arch=arm -DOS=android -f make-android +fi diff --git a/3rd/libuv-1.19.2/appveyor.yml b/3rd/libuv-1.19.2/appveyor.yml new file mode 100644 index 00000000..1b018a59 --- /dev/null +++ b/3rd/libuv-1.19.2/appveyor.yml @@ -0,0 +1,32 @@ +version: v1.18.0.build{build} + +init: + - git config --global core.autocrlf true + +install: + - cinst -y nsis + +matrix: + fast_finish: true + allow_failures: + - platform: x86 + configuration: Release + - platform: x64 + configuration: Release + +platform: + - x86 + - x64 + +configuration: + - Release + +build_script: + # Fixed tag version number if using a tag. + - cmd: if "%APPVEYOR_REPO_TAG%" == "true" set APPVEYOR_BUILD_VERSION=%APPVEYOR_REPO_TAG_NAME% + # vcbuild overwrites the platform variable. + - cmd: set ARCH=%platform% + - cmd: vcbuild.bat release %ARCH% shared + +cache: + - C:\projects\libuv\build\gyp diff --git a/3rd/libuv-1.19.2/autogen.sh b/3rd/libuv-1.19.2/autogen.sh new file mode 100644 index 00000000..271c2ee8 --- /dev/null +++ b/3rd/libuv-1.19.2/autogen.sh @@ -0,0 +1,46 @@ +#!/bin/sh + +# 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's designed +around the event-driven asynchronous I/O model. + +The library provides much more than a simple 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. +- A TCP server handle that gets 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 matches, 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 duration calculated + in 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 ends and :c:func:`uv_run` will return.

Its +core job is to provide an event loop and callback based notifications of I/O +and other activities. libuv offers core utilities like timers, non-blocking +networking support, asynchronous file system access, child processes and more. + +Event loops +----------- + +In event-driven programming, an application expresses interest in certain events +and respond to them when they occur. The responsibility of gathering events +from the operating system or monitoring other sources of events is handled by +libuv, and the user can register callbacks to be invoked when an event occurs. +The event-loop usually keeps running *forever*. In pseudocode: + +.. code-block:: python + + while there are still events to process: + e = get the next event + if there is a callback associated with e: + call the callback + +Some examples of events are: + +* File is ready for writing +* A socket has data ready to be read +* A timer has timed out + +This event loop is encapsulated by ``uv_run()`` -- the end-all function when using +libuv. + +The most common activity of systems programs is to deal with input and output, +rather than a lot of number-crunching. The problem with using conventional +input/output functions (``read``, ``fprintf``, etc.) is that they are +**blocking**. The actual write to a hard disk or reading from a network, takes +a disproportionately long time compared to the speed of the processor. The +functions don't return until the task is done, so that your program is doing +nothing. For programs which require high performance this is a major roadblock +as other activities and other I/O operations are kept waiting. + +One of the standard solutions is to use threads. Each blocking I/O operation is +started in a separate thread (or in a thread pool). When the blocking function +gets invoked in the thread, the processor can schedule another thread to run, +which actually needs the CPU. + +The approach followed by libuv uses another style, which is the **asynchronous, +non-blocking** style. Most modern operating systems provide event notification +subsystems. For example, a normal ``read`` call on a socket would block until +the sender actually sent something. Instead, the application can request the +operating system to watch the socket and put an event notification in the +queue. The application can inspect the events at its convenience (perhaps doing +some number crunching before to use the processor to the maximum) and grab the +data. It is **asynchronous** because the application expressed interest at one +point, then used the data at another point (in time and space). It is +**non-blocking** because the application process was free to do other tasks. +This fits in well with libuv's event-loop approach, since the operating system +events can be treated as just another libuv event. The non-blocking ensures +that other events can continue to be handled as fast as they come in [#]_. + +.. NOTE:: + + How the I/O is run in the background is not of our concern, but due to the + way our computer hardware works, with the thread as the basic unit of the + processor, libuv and OSes will usually run background/worker threads and/or + polling to perform tasks in a non-blocking manner. + +Bert Belder, one of the libuv core developers has a small video explaining the +architecture of libuv and its background. If you have no prior experience with +either libuv or libev, it is a quick, useful watch. + +libuv's event loop is explained in more detail in the `documentation +`_. + +.. raw:: html + + + +Hello World +----------- + +With the basics out of the way, lets write our first libuv program. It does +nothing, except start a loop which will exit immediately. + +.. rubric:: helloworld/main.c +.. literalinclude:: ../../code/helloworld/main.c + :linenos: + +This program quits immediately because it has no events to process. A libuv +event loop has to be told to watch out for events using the various API +functions. + +Starting with libuv v1.0, users should allocate the memory for the loops before +initializing it with ``uv_loop_init(uv_loop_t *)``. This allows you to plug in +custom memory management. Remember to de-initialize the loop using +``uv_loop_close(uv_loop_t *)`` and then delete the storage. The examples never +close loops since the program quits after the loop ends and the system will +reclaim memory. Production grade projects, especially long running systems +programs, should take care to release correctly. + +Default loop +++++++++++++ + +A default loop is provided by libuv and can be accessed using +``uv_default_loop()``. You should use this loop if you only want a single +loop. + +.. note:: + + node.js uses the default loop as its main loop. If you are writing bindings + you should be aware of this. + +.. _libuv-error-handling: + +Error handling +-------------- + +Initialization functions or synchronous functions which may fail return a negative number on error. Async functions that may fail will pass a status parameter to their callbacks. The error messages are defined as ``UV_E*`` `constants`_. + +.. _constants: http://docs.libuv.org/en/v1.x/errors.html#error-constants + +You can use the ``uv_strerror(int)`` and ``uv_err_name(int)`` functions +to get a ``const char *`` describing the error or the error name respectively. + +I/O read callbacks (such as for files and sockets) are passed a parameter ``nread``. If ``nread`` is less than 0, there was an error (UV_EOF is the end of file error, which you may want to handle differently). + +Handles and Requests +-------------------- + +libuv works by the user expressing interest in particular events. This is +usually done by creating a **handle** to an I/O device, timer or process. +Handles are opaque structs named as ``uv_TYPE_t`` where type signifies what the +handle is used for. + +.. rubric:: libuv watchers +.. literalinclude:: ../../../include/uv.h + :lines: 197-230 + +Handles represent long-lived objects. Async operations on such handles are +identified using **requests**. A request is short-lived (usually used across +only one callback) and usually indicates one I/O operation on a handle. +Requests are used to preserve context between the initiation and the callback +of individual actions. For example, an UDP socket is represented by +a ``uv_udp_t``, while individual writes to the socket use a ``uv_udp_send_t`` +structure that is passed to the callback after the write is done. + +Handles are setup by a corresponding:: + + uv_TYPE_init(uv_loop_t *, uv_TYPE_t *) + +function. + +Callbacks are functions which are called by libuv whenever an event the watcher +is interested in has taken place.

As +node.js grew in popularity, it was important to make it work on Windows, but +libev ran only on Unix. The Windows equivalent of kernel event notification +mechanisms like kqueue or (e)poll is IOCP. libuv was an abstraction around libev +or IOCP depending on the platform, providing users an API based on libev. +In the node-v0.9.0 version of libuv `libev was removed`_. + +Since then libuv has continued to mature and become a high quality standalone +library for system programming.

To listen for particular signals on +that handler, use ``uv_signal_start()`` with the handler function. Each handler +can only be associated with one signal number, with subsequent calls to +``uv_signal_start()`` overwriting earlier associations. Use ``uv_signal_stop()`` to +stop watching.

UV_RUN_ONCE blocks if there are no + pending events, while UV_RUN_NOWAIT will return immediately. We use NOWAIT + so that one of the loops isn't starved because the other one has no pending + activity. + +Send ``SIGUSR1`` to the process, and you'll find the handler being invoked +4 times, one for each ``uv_signal_t``. The handler just stops each handle, +so that the program exits. This sort of dispatch to all handlers is very +useful. A server using multiple event loops could ensure that all data was +safely saved before termination, simply by every loop adding a watcher for +``SIGINT``. + +Child Process I/O +----------------- + +A normal, newly spawned process has its own set of file descriptors, with 0, +1 and 2 being ``stdin``, ``stdout`` and ``stderr`` respectively. Sometimes you +may want to share file descriptors with the child. For example, perhaps your +applications launches a sub-command and you want any errors to go in the log +file, but ignore ``stdout``. For this you'd like to have ``stderr`` of the +child be the same as the stderr of the parent. In this case, libuv supports +*inheriting* file descriptors.

Just be warned that creating processes is a costly task. + +.. _pipes: + +Pipes +----- + +libuv's ``uv_pipe_t`` structure is slightly confusing to Unix programmers, +because it immediately conjures up ``|`` and `pipe(7)`_. But ``uv_pipe_t`` is +not related to anonymous pipes, rather it is an IPC mechanism. ``uv_pipe_t`` +can be backed by a `Unix Domain Socket`_ or `Windows Named Pipe`_ to allow +multiple processes to communicate. This is discussed below. + +.. _pipe(7): http://www.kernel.org/doc/man-pages/online/pages/man7/pipe.7.html +.. _Unix Domain Socket: http://www.kernel.org/doc/man-pages/online/pages/man7/unix.7.html +.. _Windows Named Pipe: http://msdn.microsoft.com/en-us/library/windows/desktop/aa365590(v=vs.85).aspx + +Parent-child IPC +++++++++++++++++ + +A parent and child can have one or two way communication over a pipe created by +settings ``uv_stdio_container_t.flags`` to a bit-wise combination of +``UV_CREATE_PIPE`` and ``UV_READABLE_PIPE`` or ``UV_WRITABLE_PIPE``.

This allows processes +to hand off their I/O to other processes. Applications include load-balancing +servers, worker processes and other ways to make optimum use of CPU. libuv only +supports sending **TCP sockets or other pipes** over pipes for now. + +To demonstrate, we will look at a echo server implementation that hands of +clients to worker processes in a round-robin fashion. This program is a bit +involved, and while only snippets are included in the book, it is recommended +to read the full code to really understand it. + +The worker process is quite simple, since the file-descriptor is handed over to +it by the master. + +.. rubric:: multi-echo-server/worker.c +.. literalinclude:: ../../code/multi-echo-server/worker.c + :linenos: + :lines: 7-9,81- + :emphasize-lines: 6-8 + +``queue`` is the pipe connected to the master process on the other end, along +which new file descriptors get sent. It is important to set the ``ipc`` +argument of ``uv_pipe_init`` to 1 to indicate this pipe will be used for +inter-process communication! Since the master will write the file handle to the +standard input of the worker, we connect the pipe to ``stdin`` using +``uv_pipe_open``. + +.. rubric:: multi-echo-server/worker.c +.. literalinclude:: ../../code/multi-echo-server/worker.c + :linenos: + :lines: 51-79 + :emphasize-lines: 10,15,20 + +First we call ``uv_pipe_pending_count()`` to ensure that a handle is available +to read out. If your program could deal with different types of handles, +``uv_pipe_pending_type()`` can be used to determine the type. +Although ``accept`` seems odd in this code, it actually makes sense. What +``accept`` traditionally does is get a file descriptor (the client) from +another file descriptor (The listening socket). Which is exactly what we do +here. Fetch the file descriptor (``client``) from ``queue``. From this point +the worker does standard echo server stuff. + +Turning now to the master, let's take a look at how the workers are launched to +allow load balancing. + +.. rubric:: multi-echo-server/main.c +.. literalinclude:: ../../code/multi-echo-server/main.c + :linenos: + :lines: 9-13 + +The ``child_worker`` structure wraps the process, and the pipe between the +master and the individual process. + +.. rubric:: multi-echo-server/main.c +.. literalinclude:: ../../code/multi-echo-server/main.c + :linenos: + :lines: 51,61-95 + :emphasize-lines: 17,20-21 + +In setting up the workers, we use the nifty libuv function ``uv_cpu_info`` to +get the number of CPUs so we can launch an equal number of workers.

We then indicate that the child process' ``stdin`` is to be +a readable pipe (from the point of view of the child). Everything is +straightforward till here. The workers are launched and waiting for file +descriptors to be written to their standard input. + +It is in ``on_new_connection`` (the TCP infrastructure is initialized in +``main()``), that we accept the client socket and pass it along to the next +worker in the round-robin. + +.. rubric:: multi-echo-server/main.c +.. literalinclude:: ../../code/multi-echo-server/main.c + :linenos: + :lines: 31-49 + :emphasize-lines: 9,12-13 + +The ``uv_write2`` call handles all the abstraction and it is simply a matter of +passing in the handle (``client``) as the right argument.

Why are we on threads? Aren't event loops supposed to be **the +way** to do *web-scale programming*? Well... no. Threads are still the medium in +which processors do their jobs. Threads are therefore mighty useful sometimes, even +though you might have to wade through various synchronization primitives. + +Threads are used internally to fake the asynchronous nature of all of the system +calls. libuv also uses threads to allow you, the application, to perform a task +asynchronously that is actually blocking, by spawning a thread and collecting +the result when it is done. + +Today there are two predominant thread libraries: the Windows threads +implementation and POSIX's `pthreads`_. libuv's thread API is analogous to +the pthreads API and often has similar semantics. + +A notable aspect of libuv's thread facilities is that it is a self contained +section within libuv.

No other thread interacts +with the event loop (except using ``uv_async_send``). + +Core thread operations +---------------------- + +There isn't much here, you just start a thread using ``uv_thread_create()`` and +wait for it to close using ``uv_thread_join()``. + +.. _thread-create-example: + +.. rubric:: thread-create/main.c +.. literalinclude:: ../../code/thread-create/main.c + :linenos: + :lines: 26-36 + :emphasize-lines: 3-7 + +.. tip:: + + ``uv_thread_t`` is just an alias for ``pthread_t`` on Unix, but this is an + implementation detail, avoid depending on it to always be true. + +The second parameter is the function which will serve as the entry point for +the thread, the last parameter is a ``void *`` argument which can be used to pass +custom parameters to the thread.

Also, they +should not be used with ``uv_cond_t`` variables. + +The default BSD mutex implementation will raise an error if a thread which has +locked a mutex attempts to lock it again. For example, a construct like:: + + uv_mutex_init(a_mutex); + uv_mutex_lock(a_mutex); + uv_thread_create(thread_id, entry, (void *)a_mutex); + uv_mutex_lock(a_mutex); + // more things here + +can be used to wait until another thread initializes some stuff and then +unlocks ``a_mutex`` but will lead to your program crashing if in debug mode, or +return an error in the second call to ``uv_mutex_lock()``. + +.. note:: + + Mutexes on Windows are always recursive. + +Locks +~~~~~ + +Read-write locks are a more granular access mechanism.

A seemingly simple function, what makes ``uv_queue_work()`` +tempting is that it allows potentially any third-party libraries to be used +with the event-loop paradigm. When you use event loops, it is *imperative to +make sure that no function which runs periodically in the loop thread blocks +when performing I/O or is a serious CPU hog*, because this means that the loop +slows down and events are not being handled at full capacity. + +However, a lot of existing code out there features blocking functions (for example +a routine which performs I/O under the hood) to be used with threads if you +want responsiveness (the classic 'one thread per client' server model), and +getting them to play with an event loop library generally involves rolling your +own system of running the task in a separate thread. libuv just provides +a convenient abstraction for this. + +Here is a simple example inspired by `node.js is cancer`_. We are going to +calculate fibonacci numbers, sleeping a bit along the way, but run it in +a separate thread so that the blocking and CPU bound task does not prevent the +event loop from performing other activities. + +.. rubric:: queue-work/main.c - lazy fibonacci +.. literalinclude:: ../../code/queue-work/main.c + :linenos: + :lines: 17-29 + +The actual task function is simple, nothing to show that it is going to be +run in a separate thread. The ``uv_work_t`` structure is the clue. You can pass +arbitrary data through it using the ``void* data`` field and use it to +communicate to and from the thread. But be sure you are using proper locks if +you are changing things while both threads may be running. + +The trigger is ``uv_queue_work``: + +.. rubric:: queue-work/main.c +.. literalinclude:: ../../code/queue-work/main.c + :linenos: + :lines: 31-44 + :emphasize-lines: 10 + +The thread function will be launched in a separate thread, passed the +``uv_work_t`` structure and once the function returns, the *after* function +will be called on the thread the event loop is running in.

The + only guarantee that libuv makes is -- The callback function is called *at + least once* after the call to ``uv_async_send``. If you have no pending + calls to ``uv_async_send``, the callback won't be called. If you make two + or more calls, and libuv hasn't had a chance to run the callback yet, it + *may* invoke your callback *only once* for the multiple invocations of + ``uv_async_send``.

The actual work being done in a separate thread wants to invoke the progress + callback, but cannot directly call into v8 to interact with JavaScript. So + it uses ``uv_async_send``. + +4.

A slight variation is to have the +``uv_work_t`` itself as the first member of this struct (called a baton [#]_). +This allows cleaning up the work request and all the data in one free call. + +.. code-block:: c + :linenos: + :emphasize-lines: 2 + + struct ftp_baton { + uv_work_t req; + char *host; + int port; + char *username; + char *password; + } + +.. code-block:: c + :linenos: + :emphasize-lines: 2 + + ftp_baton *baton = (ftp_baton*) malloc(sizeof(ftp_baton)); + baton->req.data = (void*) baton; + baton->host = strdup("my.webhost.com"); + baton->port = 21; + // ... + + uv_queue_work(loop, &baton->req, ftp_session, ftp_cleanup); + +Here we create the baton and queue the task. + +Now the task function can extract the data it needs: + +.. code-block:: c + :linenos: + :emphasize-lines: 2, 12 + + void ftp_session(uv_work_t *req) { + ftp_baton *baton = (ftp_baton*) req->data; + + fprintf(stderr, "Connecting to %s\n", baton->host); + } + + void ftp_cleanup(uv_work_t *req) { + ftp_baton *baton = (ftp_baton*) req->data; + + free(baton->host); + // ... + free(baton); + } + +We then free the baton which also frees the watcher. + +External I/O with polling +------------------------- + +Usually third-party libraries will handle their own I/O, and keep track of +their sockets and other files internally. In this case it isn't possible to use +the standard stream I/O operations, but the library can still be integrated +into the libuv event loop. All that is required is that the library allow you +to access the underlying file descriptors and provide functions that process +tasks in small increments as decided by your application. Some libraries though +will not allow such access, providing only a standard blocking function which +will perform the entire I/O transaction and only then return. It is unwise to +use these in the event loop thread, use the :ref:`libuv-work-queue` instead. Of +course, this will also mean losing granular control on the library. + +The ``uv_poll`` section of libuv simply watches file descriptors using the +operating system notification mechanism. In some sense, all the I/O operations +that libuv implements itself are also backed by ``uv_poll`` like code. Whenever +the OS notices a change of state in file descriptors being polled, libuv will +invoke the associated callback. + +Here we will walk through a simple download manager that will use libcurl_ to +download files. Rather than give all control to libcurl, we'll instead be +using the libuv event loop, and use the non-blocking, async multi_ interface to +progress with the download whenever libuv notifies of I/O readiness. + +.. _libcurl: http://curl.haxx.se/libcurl/ +.. _multi: http://curl.haxx.se/libcurl/c/libcurl-multi.html + +.. rubric:: uvwget/main.c - The setup +.. literalinclude:: ../../code/uvwget/main.c + :linenos: + :lines: 1-9,140- + :emphasize-lines: 7,21,24-25 + +The way each library is integrated with libuv will vary. In the case of +libcurl, we can register two callbacks. The socket callback ``handle_socket`` +is invoked whenever the state of a socket changes and we have to start polling +it. ``start_timeout`` is called by libcurl to notify us of the next timeout +interval, after which we should drive libcurl forward regardless of I/O status. +This is so that libcurl can handle errors or do whatever else is required to +get the download moving. + +Our downloader is to be invoked as:: + + $ ./uvwget [url1] [url2] ... + +So we add each argument as an URL + +.. rubric:: uvwget/main.c - Adding urls +.. literalinclude:: ../../code/uvwget/main.c + :linenos: + :lines: 39-56 + :emphasize-lines: 13-14 + +We let libcurl directly write the data to a file, but much more is possible if +you so desire. + +``start_timeout`` will be called immediately the first time by libcurl, so +things are set in motion. This simply starts a libuv `timer `_ which +drives ``curl_multi_socket_action`` with ``CURL_SOCKET_TIMEOUT`` whenever it +times out. ``curl_multi_socket_action`` is what drives libcurl, and what we +call whenever sockets change state. But before we go into that, we need to poll +on sockets whenever ``handle_socket`` is called. + +.. rubric:: uvwget/main.c - Setting up polling +.. literalinclude:: ../../code/uvwget/main.c + :linenos: + :lines: 102-140 + :emphasize-lines: 9,11,15,21,24 + +We are interested in the socket fd ``s``, and the ``action``. For every socket +we create a ``uv_poll_t`` handle if it doesn't exist, and associate it with the +socket using ``curl_multi_assign``. This way ``socketp`` points to it whenever +the callback is invoked. + +In the case that the download is done or fails, libcurl requests removal of the +poll. So we stop and free the poll handle. + +Depending on what events libcurl wishes to watch for, we start polling with +``UV_READABLE`` or ``UV_WRITABLE``. Now libuv will invoke the poll callback +whenever the socket is ready for reading or writing. Calling ``uv_poll_start`` +multiple times on the same handle is acceptable, it will just update the events +mask with the new value. ``curl_perform`` is the crux of this program. + +.. rubric:: uvwget/main.c - Driving libcurl. +.. literalinclude:: ../../code/uvwget/main.c + :linenos: + :lines: 81-95 + :emphasize-lines: 2,6-7,12 + +The first thing we do is to stop the timer, since there has been some progress +in the interval. Then depending on what event triggered the callback, we set +the correct flags. Then we call ``curl_multi_socket_action`` with the socket +that progressed and the flags informing about what events happened. At this +point libcurl does all of its internal tasks in small increments, and will +attempt to return as fast as possible, which is exactly what an evented program +wants in its main thread. libcurl keeps queueing messages into its own queue +about transfer progress. In our case we are only interested in transfers that +are completed.

The usage is +quite simple as long as your library exports the right symbols. Be careful with +sanity and security checks when loading third party code, otherwise your +program will behave unpredictably. This example implements a very simple +plugin system which does nothing except print the name of the plugin. + +Let us first look at the interface provided to plugin authors. + +.. rubric:: plugin/plugin.h +.. literalinclude:: ../../code/plugin/plugin.h + :linenos: + +You can similarly add more functions that plugin authors can use to do useful +things in your application [#]_. A sample plugin using this API is: + +.. rubric:: plugin/hello.c +.. literalinclude:: ../../code/plugin/hello.c + :linenos: + +Our interface defines that all plugins should have an ``initialize`` function +which will be called by the application. This plugin is compiled as a shared +library and can be loaded by running our application:: + + $ ./plugin libhello.dylib + Loading libhello.dylib + Registered plugin "Hello World!" + +.. NOTE:: + + The shared library filename will be different depending on platforms. On + Linux it is ``libhello.so``. + +This is done by using ``uv_dlopen`` to first load the shared library +``libhello.dylib``. Then we get access to the ``initialize`` function using +``uv_dlsym`` and invoke it. + +.. rubric:: plugin/main.c +.. literalinclude:: ../../code/plugin/main.c + :linenos: + :lines: 7- + :emphasize-lines: 15, 18, 24 + +``uv_dlopen`` expects a path to the shared library and sets the opaque +``uv_lib_t`` pointer. It returns 0 on success, -1 on error. Use ``uv_dlerror`` +to get the error message. + +``uv_dlsym`` stores a pointer to the symbol in the second argument in the third +argument. ``init_plugin_function`` is a function pointer to the sort of +function we are looking for in the application's plugins. + +.. _shared libraries: http://en.wikipedia.org/wiki/Shared_library#Shared_libraries + +TTY +--- + +Text terminals have supported basic formatting for a long time, with a `pretty +standardised`_ command set. This formatting is often used by programs to +improve the readability of terminal output. For example ``grep --colour``. +libuv provides the ``uv_tty_t`` abstraction (a stream) and related functions to +implement the ANSI escape codes across all platforms. By this I mean that libuv +converts ANSI codes to the Windows equivalent, and provides functions to get +terminal information. + +.. _pretty standardised: http://en.wikipedia.org/wiki/ANSI_escape_sequences + +The first thing to do is to initialize a ``uv_tty_t`` with the file descriptor +it reads/writes from. This is achieved with:: + + int uv_tty_init(uv_loop_t*, uv_tty_t*, uv_file fd, int readable) + +Set ``readable`` to true if you plan to use ``uv_read_start()`` on the stream. + +It is then best to use ``uv_tty_set_mode`` to set the mode to *normal* +which enables most TTY formatting, flow-control and other settings. Other_ modes +are also available. + +.. _Other: http://docs.libuv.org/en/v1.x/tty.html#c.uv_tty_mode_t + +Remember to call ``uv_tty_reset_mode`` when your program exits to restore the +state of the terminal. Just good manners. Another set of good manners is to be +aware of redirection. If the user redirects the output of your command to +a file, control sequences should not be written as they impede readability and +``grep``. To check if the file descriptor is indeed a TTY, call +``uv_guess_handle`` with the file descriptor and compare the return value with +``UV_TTY``. + +Here is a simple example which prints white text on a red background: + +.. rubric:: tty/main.c +.. literalinclude:: ../../code/tty/main.c + :linenos: + :emphasize-lines: 11-12,14,17,27 + +The final TTY helper is ``uv_tty_get_winsize()`` which is used to get the +width and height of the terminal and returns ``0`` on success.

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.

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.

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`.

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 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.

E.g. for libuv 1.2.3 this would be 0x010203. - - .. versionadded:: 1.7.0 - - -Functions ---------- - -.. c:function:: unsigned int uv_version(void) - - Returns :c:macro:`UV_VERSION_HEX`. - -.. c:function:: const char* uv_version_string(void) - - Returns the libuv version number as a string. For non-release versions the - version suffix is included. diff --git a/3rd/libuv-1.19.2/gyp_uv.py b/3rd/libuv-1.19.2/gyp_uv.py deleted file mode 100644 index c2add5ca..00000000 --- a/3rd/libuv-1.19.2/gyp_uv.py +++ /dev/null @@ -1,73 +0,0 @@ -#!/usr/bin/env python - -import os -import platform -import sys - -try: - import multiprocessing.synchronize - gyp_parallel_support = True -except ImportError: - gyp_parallel_support = False - - -CC = os.environ.get('CC', 'cc') -script_dir = os.path.dirname(__file__) -uv_root = os.path.normpath(script_dir) -output_dir = os.path.join(os.path.abspath(uv_root), 'out') - -sys.path.insert(0, os.path.join(uv_root, 'build', 'gyp', 'pylib')) -try: - import gyp -except ImportError: - print('You need to install gyp in build/gyp first.
