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/ChangeLog b/3rd/libuv/ChangeLog deleted file mode 100644 index 53ebd01d..00000000 --- a/3rd/libuv/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/docs/src/dll.rst b/3rd/libuv/docs/src/dll.rst deleted file mode 100644 index fb13f908..00000000 --- a/3rd/libuv/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.

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.

(4faeaea) + + + +Changes in 2.0.3-alpha (20 Nov 2009): + o Add a new code to support SSL/TLS on bufferevents, using the OpenSSL library (where available). + o Fix a bug where we didn't allocate enough memory in event_get_supported_methods(). + o Avoid segfault during failed allocation of locked evdns_base. (Found by Rocco Carbone.) + o Export new evutil_ascii_* functions to perform locale-independent character type operations. + o Try to compile better with MSVC: patches from Brodie Thiesfield + o New evconnlistener_get_fd function to expose a listener's associated socket. + o Expose an ev_socklen_t type for consistent use across platforms. + o Make bufferevent_socket_connect() work when the original fd was -1. + o Fix a bug in bufferevent_socket_connect() when the connection succeeds too quickly. + o Export an evutil_sockaddr_cmp() to compare to sockaddr objects for equality. + o Add a bufferevent_get_enabled() to tell what a bufferevent has been configured to do. + o Add an evbuffer_search_eol() function to locate the end of a line nondestructively. + o Add an evbuffer_search_range() function to search a bounded range of a buffer. + o Fix a rare crash bug in evdns. + o Have bufferevent_socket_connect() with no arguments put a bufferevent into connecting mode. + o Support sendfile on Solaris: patch from Caitlin Mercer. + o New functions to explicitly reference a socket used by an evhttp object. Patches from David Reiss. + o When we send a BEV_EVENT_CONNECTED to indicate connected status, we no longer invoke the write callback as well unless we actually wrote data too. + o If the kernel tells us that there are a negative number of bytes to read from a socket, do not believe it. Fixes bug 2841177; found by Alexander Pronchenkov. + o Do not detect whether we have monotonic clock support every time a new event base is created: instead do it only once. Patch taken from Chromium. + o Do not allocate the maximum event queue for the epoll backend at startup. Instead, start out accepting 32 events at a time, and double the queue's size when it seems that the OS is generating events faster than we're requesting them. Saves up to 374K per epoll-based event_base. Resolves bug 2839240. + o Treat an event with a negative fd as valid but untriggerable by Libevent. This is useful for applications that want to manually activate events. + o Fix compilation on Android, which forgot to define fd_mask in its sys/select.h + o Do not drop data from evbuffer when out of memory; reported by Jacek Masiulaniec + o New event_base_got_exit() and event_base_got_break() functions to tell whether an event loop exited because of an event_base_loopexit() or an event_base_loopbreak(). Patch from Ka-Hing Cheung. + o When adding or deleting an event from a non-main thread, only wake up the main thread when its behavior actually needs to change. + o Fix some bugs when using the old evdns interfaces to initialize the evdns module. + o Detect errors during bufferevent_connect(). Patch from Christopher Davis. + o Fix compilation for listener.h for C++ - missing extern "C". Patch from Ferenc Szalai. + o Make the event_base_loop() family of functions respect thread-safety better. This should clear up a few hard-to-debug race conditions. + o Fix a bug when using a specialized memory allocator on win32. + o Have the win32 select() backend label TCP-socket-connected events as EV_WRITE, not EV_READ. This should bring it in line with the other backends, and improve portability. Patch from Christopher Davis. + o Stop using enums as arguments or return values when what we mean is a bitfield of enum values. C++ doesn't believe that you can OR two enum values together and get another enum, and C++ takes its typing seriously. Patch from Christopher Davis. + o Add an API to replace all fatal calls to exit() with a user-provided panic function. + o Replace all assert() calls with a variant that is aware of the user-provided logging and panic functions. + o Add a return value to event_assign so that it can fail rather than asserting when the user gives it bad input. event_set still dies on bad input. + o The event_base_new() and event_base_new_with_config() functions now never call exit() on failure. For backward "compatibility", event_init() still does, but more consistently. + o Remove compat/sys/_time.h. It interfered with system headers on HPUX, and its functionality has been subsumed by event2/util.h and util-internal.h. + o Add a new bufferevent_socket_connect_hostname() to encapsulate the resolve-then-connect operation. + o Build kqueue.c correctly on GNU/kFreeBSD platforms. Patch pulled upstream from Debian. + o Alternative queue-based timeout algorithm for programs that use a large number of timeouts with the same value. + o New event_base_config option to disable the timeval cache entirely. + o Make EV_PERSIST timeouts more accurate: schedule the next event based on the scheduled time of the previous event, not based on the current time. + o Allow http.c to handle cases where getaddrinfo returns an IPv6 address. Patch from Ryan Phillips. + o Fix a problem with excessive memory allocation when using multiple event priorities. + o Default to using arc4random for DNS transaction IDs on systems that have it; from OpenBSD. + o Never check the environment when we're running setuid or setgid; from OpenBSD. + o Options passed to evdns_set_option() no longer need to end with a colon. + o Add an evutil_getaddrinfo() function to clone getaddrinfo on platforms that don't have it. + o Add an evdns_getaddrinfo() function to provide a nonblocking getaddrinfo using evdns, so programs can perform useful hostname lookup. + o Finally expose the IOCP-based bufferevent backend. It passes its unit tests, but probably still has some bugs remaining. Code by Nick Mathewson and Christopher Davis. + o Numerous other bugfixes. + o On FreeBSD and other OSes, connect can return ECONREFUSED immediately; instead of failing the function call, pretend with faileld in the callback. + o Fix a race condition in the pthreads test case; found by Nick Mathewson + o Remove most calls to event_err() in http and deal with memory errors instead + + + +Changes in 2.0.2-alpha (25 Jul 2009): + o Add a new flag to bufferevents to make all callbacks automatically deferred. + o Make evdns functionality locked, and automatically defer dns callbacks. + o Fix a possible free(NULL) when freeing an event_base with no signals. + o Add a flag to disable checking environment varibles when making an event_base + o Disallow setting less than 1 priority. + o Fix a bug when removing a timeout from the heap. [Patch from Marko Kreen] + o Use signal.h, not sys/signal.h. [Patch from mmadia] + o Try harder to build with certain older c99 compilers. + o Make sure that an event_config's flags field is always initialized to 0. [Bug report from Victor Goya] + o Avoid data corruption when reading data entirely into the second-to-last chain of an evbuffer. [Bug report from Victor Goya] + o Make sendfile work on FreeBSD + o Do not use vararg macros for accessing evrpc structures; this is not backwards compatible, but we did not promise any backwards compatibility for the rpc code. + o Actually define the event_config_set_flag() function. + o Try harder to compile with Visual C++. + o Move event_set() and its allies to event2/event_compat.h where they belong. + o Remove the event_gotsig code, which has long been deprecated and unused. + o Add an event_get_base() function to return the base assigned to an event. + o New function to automate connecting on a socket-based bufferevent. + o New functions to automate listening for incoming TCP connections. + o Do case-insensitive checks with a locale-independent comparison function. + o Rename the evbuffercb and everrorcb callbacks to bufferevent_data_cb and bufferevent_event_cb respectively. The old names are available in bufferevent_compat.h. + o Rename the EVBUFFER_* codes used by bufferevent event callbacks to BEV_EVENT_*, to avoid namespace collision with evbuffer flags. The old names are available in bufferevent_compat.h. + o Move the EVBUFFER_INPUT and EVBUFFER_OUTPUT macros to bufferevent_compat.h + o Add a bufferevent_getfd() function to mirror bufferevent_setfd() + o Make bufferevent_setfd() return an error code if the operation is not successful. + o Shave 22 bytes off struct event on 32-bit platforms by shrinking and re-ordering fields. The savings on 64-bit platforms is likely higher. + o Cap the maximum number of priorities at 256. + o Change the semantics of evbuffer_cb_set_flags() to be set-flag only; add a new evbuffer_cb_clear_flags() to remove set flags. + o Change the interface of evbuffer_add_reference so that the cleanup callback gets more information + o Revise the new evbuffer_reserve_space/evbuffer_commit_space() interfaces so that you can use them without causing extraneous copies or leaving gaps in the evbuffer. + o Add a new evbuffer_peek() interface to inspect data in an evbuffer without removing it. + o Fix a deadlock when suspending reads in a bufferevent due to a full buffer. (Spotted by Joachim Bauch.) + o Fix a memory error when freeing a thread-enabled event base with registered events. (Spotted by Joachim Bauch.) + o Try to contain degree of failure when running on a win32 version so heavily firewalled that we can't fake a socketpair. + o Activate fd events in a pseudorandom order with O(N) backends, so that we don't systematically favor low fds (select) or earlier-added fds (poll, win32). + o Replace some read()/write() instances with send()/recv() to work properly on win32. + o Set truncated flag correctly in evdns server replies. + o Raise RpcGenError in event_rpcgen.py; from jmanison and Zack Weinberg + o Fix preamble of rpcgen-generated files to rely on event2 includes; based on work by jmansion; patch from Zack Weinberg. + o Allow specifying the output filename for rpcgen; based on work by jmansion; patch from Zack Weinberg. + o Allow C identifiers as struct names; allow multiple comments in .rpc files; from Zack Weinberg + o Mitigate a race condition when using socket bufferevents in multiple threads. + o Use AC_SEARCH_LIBS, not AC_CHECK_LIB to avoid needless library use. + o Do not allow event_del(ev) to return while that event's callback is executing in another thread. This fixes a nasty race condition. + o event_get_supported_methods() now lists methods that have been disabled with the EVENT_NO* environment options. + o Rename encode_int[64] to evtag_encode_int[64] to avoid polluting the global namespace. The old method names are still available as macros in event2/tag_compat.h. + + + +Changes in 2.0.1-alpha (17 Apr 2009): + o free minheap on event_base_free(); from Christopher Layne + o debug cleanups in signal.c; from Christopher Layne + o provide event_base_new() that does not set the current_base global + o bufferevent_write now uses a const source argument; report from Charles Kerr + o improve documentation on event_base_loopexit; patch from Scott Lamb + o New function, event_{base_}loopbreak. Like event_loopexit, it makes an event loop stop executing and return. Unlike event_loopexit, it keeps subsequent pending events from getting executed. Patch from Scott Lamb + o Check return value of event_add in signal.c + o provide event_reinit() to reintialize an event_base after fork + o New function event_set_mem_functinons. It allows the user to give libevent replacement functions to use for memory management in place of malloc(), free(), etc. This should be generally useful for memory instrumentation, specialized allocators, and so on. + o The kqueue implementation now catches signals that are raised after event_add() is called but before the event_loop() call. This makes it match the other implementations. + o The kqueue implementation now restores original signal handlers correctly when its signal events are removed. + o Check return value of event_add in signal.c + o Add a more powerful evbuffer_readln as a replacement for evbuffer_readline. The new function handles more newline styles, and is more useful with buffers that may contain a nul characters. + o Do not mangle socket handles on 64-bit windows. + o The configure script now takes an --enable-gcc-warnigns option that turns on many optional gcc warnings. (Nick has been building with these for a while, but they might be useful to other developers.) + o move EV_PERSIST handling out of the event backends + o small improvements to evhttp documentation + o always generate Date and Content-Length headers for HTTP/1.1 replies + o set the correct event base for HTTP close events + o When building with GCC, use the "format" attribute to verify type correctness of calls to printf-like functions. + o Rewrite win32.c backend to be O(n lg n) rather than O(n^2). + o Removed obsoleted recalc code + o support for 32-bit tag numbers in rpc structures; this is wire compatible, but changes the API slightly. + o pull setters/getters out of RPC structures into a base class to which we just need to store a pointer; this reduces the memory footprint of these structures. + o prefix {encode,decode}_tag functions with evtag to avoid collisions + o fix a bug with event_rpcgen for integers + o Correctly handle DNS replies with no answers set (Fixes bug 1846282) + o add -Wstrict-aliasing to warnings and more cleanup + o removed linger from http server socket; reported by Ilya Martynov + o event_rpcgen now allows creating integer arrays + o support string arrays in event_rpcgen + o change evrpc hooking to allow pausing of RPCs; this will make it possible for the hook to do some meaning ful work; this is not backwards compatible. + o allow an http request callback to take ownership of a request structure + o allow association of meta data with RPC requests for hook processing + o associate more context for hooks to query such as the connection object + o remove pending timeouts on event_base_free() + o also check EAGAIN for Solaris' event ports; from W.C.A. Wijngaards + o devpoll and evport need reinit; tested by W.C.A Wijngaards + o event_base_get_method; from Springande Ulv + o Send CRLF after each chunk in HTTP output, for compliance with RFC2626. Patch from "propanbutan". Fixes bug 1894184. + o Add a int64_t parsing function, with unit tests, so we can apply Scott Lamb's fix to allow large HTTP values. + o Use a 64-bit field to hold HTTP content-lengths.

We hope that cmake will +still be supported in future versions of Libevent, and will try to +make sure that happens.) + +First of all install . + +To build libevent using Microsoft Visual studio open the "Visual Studio Command prompt" and type: + +``` +$ cd +$ mkdir build && cd build +$ cmake -G "Visual Studio 10" .. # Or whatever generator you want to use cmake --help for a list. +$ start libevent.sln +``` + +In the above, the ".." refers to the dir containing the Libevent source code. +You can build multiple versions (with different compile time settings) from the same source tree +by creating other build directories. + +It is highly recommended to build "out of source" when using +CMake instead of "in source" like the normal behaviour of autoconf for this reason. + +The "NMake Makefiles" CMake generator can be used to build entirely via the command line. + +To get a list of settings available for the project you can type: + +``` +$ cmake -LH .. +``` + +### GUI + +CMake also provides a GUI that lets you specify the source directory and output (binary) directory +that the build should be placed in. + +### OpenSSL support + +To build Libevent with OpenSSL support you will need to have OpenSSL binaries available when building, +these can be found here: + +# 2.

Before you use this library you should see if libc +can do the job for you with the modern async call getaddrinfo_a +(see http://www.imperialviolet.org/page25.html#e498). Otherwise, +please continue. +.Pp +This code is based on libevent and you must call event_init before +any of the APIs in this file. You must also seed the OpenSSL random +source if you are using OpenSSL for ids (see below). +.Pp +This library is designed to be included and shipped with your source +code. You statically link with it. You should also test for the +existence of strtok_r and define HAVE_STRTOK_R if you have it. +.Pp +The DNS protocol requires a good source of id numbers and these +numbers should be unpredictable for spoofing reasons. There are +three methods for generating them here and you must define exactly +one of them. In increasing order of preference: +.Pp +.Bl -tag -width "DNS_USE_GETTIMEOFDAY_FOR_ID" -compact -offset indent +.It DNS_USE_GETTIMEOFDAY_FOR_ID +Using the bottom 16 bits of the usec result from gettimeofday. This +is a pretty poor solution but should work anywhere. +.It DNS_USE_CPU_CLOCK_FOR_ID +Using the bottom 16 bits of the nsec result from the CPU's time +counter. This is better, but may not work everywhere. Requires +POSIX realtime support and you'll need to link against -lrt on +glibc systems at least. +.It DNS_USE_OPENSSL_FOR_ID +Uses the OpenSSL RAND_bytes call to generate the data. You must +have seeded the pool before making any calls to this library. +.El +.Pp +The library keeps track of the state of nameservers and will avoid +them when they go down. Otherwise it will round robin between them. +.Pp +Quick start guide: + #include "evdns.h" + void callback(int result, char type, int count, int ttl, + void *addresses, void *arg); + evdns_resolv_conf_parse(DNS_OPTIONS_ALL, "/etc/resolv.conf"); + evdns_resolve("www.hostname.com", 0, callback, NULL); +.Pp +When the lookup is complete the callback function is called. The +first argument will be one of the DNS_ERR_* defines in evdns.h. +Hopefully it will be DNS_ERR_NONE, in which case type will be +DNS_IPv4_A, count will be the number of IP addresses, ttl is the time +which the data can be cached for (in seconds), addresses will point +to an array of uint32_t's and arg will be whatever you passed to +evdns_resolve. +.Pp +Searching: +.Pp +In order for this library to be a good replacement for glibc's resolver it +supports searching. This involves setting a list of default domains, in +which names will be queried for. The number of dots in the query name +determines the order in which this list is used. +.Pp +Searching appears to be a single lookup from the point of view of the API, +although many DNS queries may be generated from a single call to +evdns_resolve. Searching can also drastically slow down the resolution +of names. +.Pp +To disable searching: +.Bl -enum -compact -offset indent +.It +Never set it up. If you never call +.Fn evdns_resolv_conf_parse, +.Fn evdns_init, +or +.Fn evdns_search_add +then no searching will occur. +.It +If you do call +.Fn evdns_resolv_conf_parse +then don't pass +.Va DNS_OPTION_SEARCH +(or +.Va DNS_OPTIONS_ALL, +which implies it). +.It +When calling +.Fn evdns_resolve, +pass the +.Va DNS_QUERY_NO_SEARCH +flag. +.El +.Pp +The order of searches depends on the number of dots in the name. If the +number is greater than the ndots setting then the names is first tried +globally. Otherwise each search domain is appended in turn. +.Pp +The ndots setting can either be set from a resolv.conf, or by calling +evdns_search_ndots_set. +.Pp +For example, with ndots set to 1 (the default) and a search domain list of +["myhome.net"]: + Query: www + Order: www.myhome.net, www. +.Pp + Query: www.abc + Order: www.abc., www.abc.myhome.net +.Pp +.Sh API reference +.Pp +.Bl -tag -width 0123456 +.It Ft int Fn evdns_init +Initializes support for non-blocking name resolution by calling +.Fn evdns_resolv_conf_parse +on UNIX and +.Fn evdns_config_windows_nameservers +on Windows. +.It Ft int Fn evdns_nameserver_add "unsigned long int address" +Add a nameserver.

The name parameter should be a DNS name. +The flags parameter should be 0, or DNS_QUERY_NO_SEARCH +which disables searching for this query.

The first is the inflight queue. In +this queue requests have an allocated transaction id and nameserver. +They will soon be transmitted if they haven't already been. +.Pp +The second is the waiting queue. The size of the inflight ring is +limited and all other requests wait in waiting queue for space. This +bounds the number of concurrent requests so that we don't flood the +nameserver. Several algorithms require a full walk of the inflight +queue and so bounding its size keeps thing going nicely under huge +(many thousands of requests) loads. +.Pp +If a nameserver loses too many requests it is considered down and we +try not to use it. After a while we send a probe to that nameserver +(a lookup for google.com) and, if it replies, we consider it working +again. If the nameserver fails a probe we wait longer to try again +with the next probe. +.Sh SEE ALSO +.Xr event 3 , +.Xr gethostbyname 3 , +.Xr resolv.conf 5 +.Sh HISTORY +The +.Nm evdns +API was developed by Adam Langley on top of the +.Nm libevent +API. +The code was integrate into +.Nm Tor +by Nick Mathewson and finally put into +.Nm libevent +itself by Niels Provos. +.Sh AUTHORS +The +.Nm evdns +API and code was written by Adam Langley with significant +contributions by Nick Mathewson. +.Sh BUGS +This documentation is neither complete nor authoritative. +If you are in doubt about the usage of this API then +check the source code to find out how it works, write +up the missing piece of documentation and send it to +me for inclusion in this man page. diff --git a/3rd/libevent/evdns.c b/3rd/libevent/evdns.c new file mode 100644 index 00000000..e9dbc35c --- /dev/null +++ b/3rd/libevent/evdns.c @@ -0,0 +1,4767 @@ +/* Copyright 2006-2007 Niels Provos + * Copyright 2007-2012 Nick Mathewson and Niels Provos + * + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions + * are met: + * 1.

event +API provides a mechanism to execute a function when a specific event +on a file descriptor occurs or after a given time has passed. +.Pp +The +.Nm event +API needs to be initialized with +.Fn event_init +before it can be used. +.Pp +In order to process events, an application needs to call +.Fn event_dispatch . +This function only returns on error, and should replace the event core +of the application program. +.Pp +The function +.Fn event_set +prepares the event structure +.Fa ev +to be used in future calls to +.Fn event_add +and +.Fn event_del . +The event will be prepared to call the function specified by the +.Fa fn +argument with an +.Fa int +argument indicating the file descriptor, a +.Fa short +argument indicating the type of event, and a +.Fa void * +argument given in the +.Fa arg +argument. +The +.Fa fd +indicates the file descriptor that should be monitored for events. +The events can be either +.Va EV_READ , +.Va EV_WRITE , +or both, +indicating that an application can read or write from the file descriptor +respectively without blocking. +.Pp +The function +.Fa fn +will be called with the file descriptor that triggered the event and +the type of event which will be either +.Va EV_TIMEOUT , +.Va EV_SIGNAL , +.Va EV_READ , +or +.Va EV_WRITE . +Additionally, an event which has registered interest in more than one of the +preceeding events, via bitwise-OR to +.Fn event_set , +can provide its callback function with a bitwise-OR of more than one triggered +event. +The additional flag +.Va EV_PERSIST +makes an +.Fn event_add +persistent until +.Fn event_del +has been called. +.Pp +Once initialized, the +.Fa ev +structure can be used repeatedly with +.Fn event_add +and +.Fn event_del +and does not need to be reinitialized unless the function called and/or +the argument to it are to be changed. +However, when an +.Fa ev +structure has been added to libevent using +.Fn event_add +the structure must persist until the event occurs (assuming +.Fa EV_PERSIST +is not set) or is removed +using +.Fn event_del . +You may not reuse the same +.Fa ev +structure for multiple monitored descriptors; each descriptor +needs its own +.Fa ev . +.Pp +The function +.Fn event_add +schedules the execution of the +.Fa ev +event when the event specified in +.Fn event_set +occurs or in at least the time specified in the +.Fa tv . +If +.Fa tv +is +.Dv NULL , +no timeout occurs and the function will only be called +if a matching event occurs on the file descriptor. +The event in the +.Fa ev +argument must be already initialized by +.Fn event_set +and may not be used in calls to +.Fn event_set +until it has timed out or been removed with +.Fn event_del . +If the event in the +.Fa ev +argument already has a scheduled timeout, the old timeout will be +replaced by the new one. +.Pp +The function +.Fn event_del +will cancel the event in the argument +.Fa ev . +If the event has already executed or has never been added +the call will have no effect. +.Pp +The functions +.Fn evtimer_set , +.Fn evtimer_add , +.Fn evtimer_del , +.Fn evtimer_initialized , +and +.Fn evtimer_pending +are abbreviations for common situations where only a timeout is required. +The file descriptor passed will be \-1, and the event type will be +.Va EV_TIMEOUT . +.Pp +The functions +.Fn signal_set , +.Fn signal_add , +.Fn signal_del , +.Fn signal_initialized , +and +.Fn signal_pending +are abbreviations. +The event type will be a persistent +.Va EV_SIGNAL . +That means +.Fn signal_set +adds +.Va EV_PERSIST . +.Pp +In order to avoid races in signal handlers, the +.Nm event +API provides two variables: +.Va event_sigcb +and +.Va event_gotsig . +A signal handler +sets +.Va event_gotsig +to indicate that a signal has been received. +The application sets +.Va event_sigcb +to a callback function. +After the signal handler sets +.Va event_gotsig , +.Nm event_dispatch +will execute the callback function to process received signals. +The callback returns 1 when no events are registered any more. +It can return \-1 to indicate an error to the +.Nm event +library, causing +.Fn event_dispatch +to terminate with +.Va errno +set to +.Er EINTR . +.Pp +The function +.Fn event_once +is similar to +.Fn event_set . +However, it schedules a callback to be called exactly once and does not +require the caller to prepare an +.Fa event +structure. +This function supports +.Fa EV_TIMEOUT , +.Fa EV_READ , +and +.Fa EV_WRITE . +.Pp +The +.Fn event_pending +function can be used to check if the event specified by +.Fa event +is pending to run. +If +.Va EV_TIMEOUT +was specified and +.Fa tv +is not +.Dv NULL , +the expiration time of the event will be returned in +.Fa tv . +.Pp +The +.Fn event_initialized +macro can be used to check if an event has been initialized. +.Pp +The +.Nm event_loop +function provides an interface for single pass execution of pending +events. +The flags +.Va EVLOOP_ONCE +and +.Va EVLOOP_NONBLOCK +are recognized. +The +.Nm event_loopexit +function exits from the event loop. The next +.Fn event_loop +iteration after the +given timer expires will complete normally (handling all queued events) then +exit without blocking for events again. Subsequent invocations of +.Fn event_loop +will proceed normally. +The +.Nm event_loopbreak +function exits from the event loop immediately. +.Fn event_loop +will abort after the next event is completed; +.Fn event_loopbreak +is typically invoked from this event's callback. This behavior is analogous +to the "break;" statement. Subsequent invocations of +.Fn event_loop +will proceed normally. +.Pp +It is the responsibility of the caller to provide these functions with +pre-allocated event structures. +.Pp +.Sh EVENT PRIORITIES +By default +.Nm libevent +schedules all active events with the same priority. +However, sometimes it is desirable to process some events with a higher +priority than others. +For that reason, +.Nm libevent +supports strict priority queues. +Active events with a lower priority are always processed before events +with a higher priority. +.Pp +The number of different priorities can be set initially with the +.Fn event_priority_init +function. +This function should be called before the first call to +.Fn event_dispatch . +The +.Fn event_priority_set +function can be used to assign a priority to an event. +By default, +.Nm libevent +assigns the middle priority to all events unless their priority +is explicitly set. +.Sh THREAD SAFE EVENTS +.Nm Libevent +has experimental support for thread-safe events. +When initializing the library via +.Fn event_init , +an event base is returned. +This event base can be used in conjunction with calls to +.Fn event_base_set , +.Fn event_base_dispatch , +.Fn event_base_loop , +.Fn event_base_loopexit , +.Fn bufferevent_base_set +and +.Fn event_base_free . +.Fn event_base_set +should be called after preparing an event with +.Fn event_set , +as +.Fn event_set +assigns the provided event to the most recently created event base. +.Fn bufferevent_base_set +should be called after preparing a bufferevent with +.Fn bufferevent_new . +.Fn event_base_free +should be used to free memory associated with the event base +when it is no longer needed. +.Sh BUFFERED EVENTS +.Nm libevent +provides an abstraction on top of the regular event callbacks. +This abstraction is called a +.Va "buffered event" . +A buffered event provides input and output buffers that get filled +and drained automatically. +The user of a buffered event no longer deals directly with the IO, +but instead is reading from input and writing to output buffers. +.Pp +A new bufferevent is created by +.Fn bufferevent_new . +The parameter +.Fa fd +specifies the file descriptor from which data is read and written to. +This file descriptor is not allowed to be a +.Xr pipe 2 . +The next three parameters are callbacks. +The read and write callback have the following form: +.Ft void +.Fn "(*cb)" "struct bufferevent *bufev" "void *arg" . +The error callback has the following form: +.Ft void +.Fn "(*cb)" "struct bufferevent *bufev" "short what" "void *arg" . +The argument is specified by the fourth parameter +.Fa "cbarg" . +A +.Fa bufferevent struct +pointer is returned on success, NULL on error. +Both the read and the write callback may be NULL. +The error callback has to be always provided. +.Pp +Once initialized, the bufferevent structure can be used repeatedly with +bufferevent_enable() and bufferevent_disable(). +The flags parameter can be a combination of +.Va EV_READ +and +.Va EV_WRITE . +When read enabled the bufferevent will try to read from the file +descriptor and call the read callback. +The write callback is executed +whenever the output buffer is drained below the write low watermark, +which is +.Va 0 +by default. +.Pp +The +.Fn bufferevent_write +function can be used to write data to the file descriptor. +The data is appended to the output buffer and written to the descriptor +automatically as it becomes available for writing. +.Fn bufferevent_write +returns 0 on success or \-1 on failure. +The +.Fn bufferevent_read +function is used to read data from the input buffer, +returning the amount of data read. +.Pp +If multiple bases are in use, bufferevent_base_set() must be called before +enabling the bufferevent for the first time. +.Sh NON-BLOCKING HTTP SUPPORT +.Nm libevent +provides a very thin HTTP layer that can be used both to host an HTTP +server and also to make HTTP requests. +An HTTP server can be created by calling +.Fn evhttp_new . +It can be bound to any port and address with the +.Fn evhttp_bind_socket +function. +When the HTTP server is no longer used, it can be freed via +.Fn evhttp_free . +.Pp +To be notified of HTTP requests, a user needs to register callbacks with the +HTTP server. +This can be done by calling +.Fn evhttp_set_cb . +The second argument is the URI for which a callback is being registered. +The corresponding callback will receive an +.Va struct evhttp_request +object that contains all information about the request. +.Pp +This section does not document all the possible function calls; please +check +.Va event.h +for the public interfaces. +.Sh ADDITIONAL NOTES +It is possible to disable support for +.Va epoll , kqueue , devpoll , poll +or +.Va select +by setting the environment variable +.Va EVENT_NOEPOLL , EVENT_NOKQUEUE , EVENT_NODEVPOLL , EVENT_NOPOLL +or +.Va EVENT_NOSELECT , +respectively. +By setting the environment variable +.Va EVENT_SHOW_METHOD , +.Nm libevent +displays the kernel notification method that it uses. +.Sh RETURN VALUES +Upon successful completion +.Fn event_add +and +.Fn event_del +return 0. +Otherwise, \-1 is returned and the global variable errno is +set to indicate the error. +.Sh SEE ALSO +.Xr kqueue 2 , +.Xr poll 2 , +.Xr select 2 , +.Xr evdns 3 , +.Xr timeout 9 +.Sh HISTORY +The +.Nm event +API manpage is based on the +.Xr timeout 9 +manpage by Artur Grabowski. +The port of +.Nm libevent +to Windows is due to Michael A. Davis. +Support for real-time signals is due to Taral. +.Sh AUTHORS +The +.Nm event +library was written by Niels Provos. +.Sh BUGS +This documentation is neither complete nor authoritative. +If you are in doubt about the usage of this API then +check the source code to find out how it works, write +up the missing piece of documentation and send it to +me for inclusion in this man page. diff --git a/3rd/libevent/event.c b/3rd/libevent/event.c new file mode 100644 index 00000000..503003e2 --- /dev/null +++ b/3rd/libevent/event.c @@ -0,0 +1,3940 @@ +/* + * Copyright (c) 2000-2007 Niels Provos + * Copyright (c) 2007-2012 Niels Provos and Nick Mathewson + * + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions + * are met: + * 1.

PEP418 [1] has a nice roundup of the issues here. + + There's GetTickCount64() on Vista and later, which gives a number of 1-msec + ticks since startup. The accuracy here might be as bad as 10-20 msec, I + hear. There's an undocumented function (NtSetTimerResolution) that + allegedly increases the accuracy. Good luck! + + There's also GetTickCount(), which is only 32 bits, but seems to be + supported on pre-Vista versions of Windows. Apparently, you can coax + another 14 bits out of it, giving you 2231 years before rollover. + + The less said about timeGetTime() the better. + + "We don't care. We don't have to. We're the Phone Company." + -- Lily Tomlin, SNL + + Our strategy, if precise timers are turned off, is to just use the best + GetTickCount equivalent available. If we've been asked for precise timing, + then we mostly[2] assume that GetTickCount is monotonic, and correct + GetPerformanceCounter to approximate it. + + [1] http://www.python.org/dev/peps/pep-0418 + [2] Of course, we feed the Windows stuff into adjust_monotonic_time() + anyway, just in case it isn't. + + */ +/* + Parts of our logic in the win32 timer code here are closely based on + BitTorrent's libUTP library.

As a + result, evbuffers can be used to pass data around without actually + incurring the overhead of copying the data. + + A new evbuffer can be allocated with evbuffer_new(), and can be + freed with evbuffer_free(). Most users will be using evbuffers via + the bufferevent interface. To access a bufferevent's evbuffers, use + bufferevent_get_input() and bufferevent_get_output(). + + There are several guidelines for using evbuffers. + + - if you already know how much data you are going to add as a result + of calling evbuffer_add() multiple times, it makes sense to use + evbuffer_expand() first to make sure that enough memory is allocated + before hand. + + - evbuffer_add_buffer() adds the contents of one buffer to the other + without incurring any unnecessary memory copies. + + - evbuffer_add() and evbuffer_add_buffer() do not mix very well: + if you use them, you will wind up with fragmented memory in your + buffer. + + - For high-performance code, you may want to avoid copying data into and out + of buffers. You can skip the copy step by using + evbuffer_reserve_space()/evbuffer_commit_space() when writing into a + buffer, and evbuffer_peek() when reading. + + In Libevent 2.0 and later, evbuffers are represented using a linked + list of memory chunks, with pointers to the first and last chunk in + the chain. + + As the contents of an evbuffer can be stored in multiple different + memory blocks, it cannot be accessed directly. Instead, evbuffer_pullup() + can be used to force a specified number of bytes to be contiguous. This + will cause memory reallocation and memory copies if the data is split + across multiple blocks.

Before you use this library you should see if libc + * can do the job for you with the modern async call getaddrinfo_a + * (see http://www.imperialviolet.org/page25.html#e498). Otherwise, + * please continue. + * + * The library keeps track of the state of nameservers and will avoid + * them when they go down. Otherwise it will round robin between them. + * + * Quick start guide: + * #include "evdns.h" + * void callback(int result, char type, int count, int ttl, + * void *addresses, void *arg); + * evdns_resolv_conf_parse(DNS_OPTIONS_ALL, "/etc/resolv.conf"); + * evdns_resolve("www.hostname.com", 0, callback, NULL); + * + * When the lookup is complete the callback function is called. The + * first argument will be one of the DNS_ERR_* defines in evdns.h. + * Hopefully it will be DNS_ERR_NONE, in which case type will be + * DNS_IPv4_A, count will be the number of IP addresses, ttl is the time + * which the data can be cached for (in seconds), addresses will point + * to an array of uint32_t's and arg will be whatever you passed to + * evdns_resolve. + * + * Searching: + * + * In order for this library to be a good replacement for glibc's resolver it + * supports searching. This involves setting a list of default domains, in + * which names will be queried for. The number of dots in the query name + * determines the order in which this list is used. + * + * Searching appears to be a single lookup from the point of view of the API, + * although many DNS queries may be generated from a single call to + * evdns_resolve. Searching can also drastically slow down the resolution + * of names. + * + * To disable searching: + * 1. Never set it up. If you never call evdns_resolv_conf_parse or + * evdns_search_add then no searching will occur. + * + * 2. If you do call evdns_resolv_conf_parse then don't pass + * DNS_OPTION_SEARCH (or DNS_OPTIONS_ALL, which implies it). + * + * 3. When calling evdns_resolve, pass the DNS_QUERY_NO_SEARCH flag. + * + * The order of searches depends on the number of dots in the name. If the + * number is greater than the ndots setting then the names is first tried + * globally. Otherwise each search domain is appended in turn. + * + * The ndots setting can either be set from a resolv.conf, or by calling + * evdns_search_ndots_set. + * + * For example, with ndots set to 1 (the default) and a search domain list of + * ["myhome.net"]: + * Query: www + * Order: www.myhome.net, www. + * + * Query: www.abc + * Order: www.abc., www.abc.myhome.net + * + * Internals: + * + * Requests are kept in two queues. The first is the inflight queue. In + * this queue requests have an allocated transaction id and nameserver. + * They will soon be transmitted if they haven't already been. + * + * The second is the waiting queue. The size of the inflight ring is + * limited and all other requests wait in waiting queue for space. This + * bounds the number of concurrent requests so that we don't flood the + * nameserver. Several algorithms require a full walk of the inflight + * queue and so bounding its size keeps thing going nicely under huge + * (many thousands of requests) loads. + * + * If a nameserver loses too many requests it is considered down and we + * try not to use it. After a while we send a probe to that nameserver + * (a lookup for google.com) and, if it replies, we consider it working + * again. If the nameserver fails a probe we wait longer to try again + * with the next probe. + */ + +#ifndef EVENT2_DNS_H_INCLUDED_ +#define EVENT2_DNS_H_INCLUDED_ + +#include + +#ifdef __cplusplus +extern "C" { +#endif + +/* For integer types. */ +#include + +/** Error codes 0-5 are as described in RFC 1035. */ +#define DNS_ERR_NONE 0 +/** The name server was unable to interpret the query */ +#define DNS_ERR_FORMAT 1 +/** The name server was unable to process this query due to a problem with the + * name server */ +#define DNS_ERR_SERVERFAILED 2 +/** The domain name does not exist */ +#define DNS_ERR_NOTEXIST 3 +/** The name server does not support the requested kind of query */ +#define DNS_ERR_NOTIMPL 4 +/** The name server refuses to reform the specified operation for policy + * reasons */ +#define DNS_ERR_REFUSED 5 +/** The reply was truncated or ill-formatted */ +#define DNS_ERR_TRUNCATED 65 +/** An unknown error occurred */ +#define DNS_ERR_UNKNOWN 66 +/** Communication with the server timed out */ +#define DNS_ERR_TIMEOUT 67 +/** The request was canceled because the DNS subsystem was shut down. */ +#define DNS_ERR_SHUTDOWN 68 +/** The request was canceled via a call to evdns_cancel_request */ +#define DNS_ERR_CANCEL 69 +/** There were no answers and no error condition in the DNS packet. + * This can happen when you ask for an address that exists, but a record + * type that doesn't. */ +#define DNS_ERR_NODATA 70 + +#define DNS_IPv4_A 1 +#define DNS_PTR 2 +#define DNS_IPv6_AAAA 3 + +#define DNS_QUERY_NO_SEARCH 1 + +#define DNS_OPTION_SEARCH 1 +#define DNS_OPTION_NAMESERVERS 2 +#define DNS_OPTION_MISC 4 +#define DNS_OPTION_HOSTSFILE 8 +#define DNS_OPTIONS_ALL 15 + +/* Obsolete name for DNS_QUERY_NO_SEARCH */ +#define DNS_NO_SEARCH DNS_QUERY_NO_SEARCH + +/** + * The callback that contains the results from a lookup. + * - result is one of the DNS_ERR_* values (DNS_ERR_NONE for success) + * - type is either DNS_IPv4_A or DNS_PTR or DNS_IPv6_AAAA + * - count contains the number of addresses of form type + * - ttl is the number of seconds the resolution may be cached for. + * - addresses needs to be cast according to type.

The Libevent API provides a mechanism to execute a callback + function when a specific event occurs on a file descriptor or after a + timeout has been reached. Furthermore, Libevent also support callbacks due + to signals or regular timeouts. + + Libevent is meant to replace the event loop found in event driven network + servers. An application just needs to call event_base_dispatch() and then add or + remove events dynamically without having to change the event loop. + + + Currently, Libevent supports /dev/poll, kqueue(2), select(2), poll(2), + epoll(4), and evports. The internal event mechanism is completely + independent of the exposed event API, and a simple update of Libevent can + provide new functionality without having to redesign the applications. As a + result, Libevent allows for portable application development and provides + the most scalable event notification mechanism available on an operating + system. Libevent can also be used for multithreaded programs. Libevent + should compile on Linux, *BSD, Mac OS X, Solaris and, Windows. + + @section usage Standard usage + + Every program that uses Libevent must include the + header, and pass the -levent flag to the linker. (You can instead link + -levent_core if you only want the main event and buffered IO-based code, + and don't want to link any protocol code.) + + @section setup Library setup + + Before you call any other Libevent functions, you need to set up the + library. If you're going to use Libevent from multiple threads in a + multithreaded application, you need to initialize thread support -- + typically by using evthread_use_pthreads() or + evthread_use_windows_threads(). See for more + information. + + This is also the point where you can replace Libevent's memory + management functions with event_set_mem_functions, and enable debug mode + with event_enable_debug_mode(). + + @section base Creating an event base + + Next, you need to create an event_base structure, using event_base_new() + or event_base_new_with_config(). The event_base is responsible for + keeping track of which events are "pending" (that is to say, being + watched to see if they become active) and which events are "active". + Every event is associated with a single event_base. + + @section event Event notification + + For each file descriptor that you wish to monitor, you must create an + event structure with event_new(). (You may also declare an event + structure and call event_assign() to initialize the members of the + structure.) To enable notification, you add the structure to the list + of monitored events by calling event_add(). The event structure must + remain allocated as long as it is active, so it should generally be + allocated on the heap. + + @section loop Dispatching events. + + Finally, you call event_base_dispatch() to loop and dispatch events. + You can also use event_base_loop() for more fine-grained control. + + Currently, only one thread can be dispatching a given event_base at a + time. If you want to run events in multiple threads at once, you can + either have a single event_base whose events add work to a work queue, + or you can create multiple event_base objects. + + @section bufferevent I/O Buffers + + Libevent provides a buffered I/O abstraction on top of the regular event + callbacks. This abstraction is called a bufferevent. A bufferevent + provides input and output buffers that get filled and drained + automatically. The user of a buffered event no longer deals directly + with the I/O, but instead is reading from input and writing to output + buffers. + + Once initialized via bufferevent_socket_new(), the bufferevent structure + can be used repeatedly with bufferevent_enable() and + bufferevent_disable(). Instead of reading and writing directly to a + socket, you would call bufferevent_read() and bufferevent_write(). + + When read enabled the bufferevent will try to read from the file descriptor + and call the read callback. The write callback is executed whenever the + output buffer is drained below the write low watermark, which is 0 by + default. + + See for more information. + + @section timers Timers + + Libevent can also be used to create timers that invoke a callback after a + certain amount of time has expired. The evtimer_new() macro returns + an event struct to use as a timer. To activate the timer, call + evtimer_add(). Timers can be deactivated by calling evtimer_del(). + (These macros are thin wrappers around event_new(), event_add(), + and event_del(); you can also use those instead.) + + @section evdns Asynchronous DNS resolution + + Libevent provides an asynchronous DNS resolver that should be used instead + of the standard DNS resolver functions. See the + functions for more detail. + + @section evhttp Event-driven HTTP servers + + Libevent provides a very simple event-driven HTTP server that can be + embedded in your program and used to service HTTP requests. + + To use this capability, you need to include the header in your + program. See that header for more information. + + @section evrpc A framework for RPC servers and clients + + Libevent provides a framework for creating RPC servers and clients.

Events come into existence via + * event_assign() or event_new(), and are then neither active nor pending. + * + * To make an event pending, pass it to event_add().

When we've - reached EOF, `nread` will be set to ``UV_EOF``. When `nread` < 0, - the `buf` parameter might not point to a valid buffer; in that case - `buf.len` and `buf.base` are both set to 0. - - .. note:: - `nread` might be 0, which does *not* indicate an error or EOF. This - is equivalent to ``EAGAIN`` or ``EWOULDBLOCK`` under ``read(2)``. - - The callee is responsible for stopping closing the stream when an error happens - by calling :c:func:`uv_read_stop` or :c:func:`uv_close`. Trying to read - from the stream again is undefined. - - The callee is responsible for freeing the buffer, libuv does not reuse it. - The buffer may be a null buffer (where buf->base=NULL and buf->len=0) on - error. - -.. c:type:: void (*uv_write_cb)(uv_write_t* req, int status) - - Callback called after data was written on a stream. `status` will be 0 in - case of success, < 0 otherwise. - -.. c:type:: void (*uv_connect_cb)(uv_connect_t* req, int status) - - Callback called after a connection started by :c:func:`uv_connect` is done. - `status` will be 0 in case of success, < 0 otherwise. - -.. c:type:: void (*uv_shutdown_cb)(uv_shutdown_t* req, int status) - - Callback called after a shutdown request has been completed. `status` will - be 0 in case of success, < 0 otherwise. - -.. c:type:: void (*uv_connection_cb)(uv_stream_t* server, int status) - - Callback called when a stream server has received an incoming connection. - The user can accept the connection by calling :c:func:`uv_accept`. - `status` will be 0 in case of success, < 0 otherwise. - - -Public members -^^^^^^^^^^^^^^ - -.. c:member:: size_t uv_stream_t.write_queue_size - - Contains the amount of queued bytes waiting to be sent. Readonly. - -.. c:member:: uv_stream_t* uv_connect_t.handle - - Pointer to the stream where this connection request is running. - -.. c:member:: uv_stream_t* uv_shutdown_t.handle - - Pointer to the stream where this shutdown request is running. - -.. c:member:: uv_stream_t* uv_write_t.handle - - Pointer to the stream where this write request is running. - -.. c:member:: uv_stream_t* uv_write_t.send_handle - - Pointer to the stream being sent using this write request. - -.. seealso:: The :c:type:`uv_handle_t` members also apply. - - -API ---- - -.. c:function:: int uv_shutdown(uv_shutdown_t* req, uv_stream_t* handle, uv_shutdown_cb cb) - - Shutdown the outgoing (write) side of a duplex stream. It waits for pending - write requests to complete. The `handle` should refer to a initialized stream. - `req` should be an uninitialized shutdown request struct. The `cb` is called - after shutdown is complete. - -.. c:function:: int uv_listen(uv_stream_t* stream, int backlog, uv_connection_cb cb) - - Start listening for incoming connections. `backlog` indicates the number of - connections the kernel might queue, same as :man:`listen(2)`. When a new - incoming connection is received the :c:type:`uv_connection_cb` callback is - called. - -.. c:function:: int uv_accept(uv_stream_t* server, uv_stream_t* client) - - This call is used in conjunction with :c:func:`uv_listen` to accept incoming - connections. Call this function after receiving a :c:type:`uv_connection_cb` - to accept the connection. Before calling this function the client handle must - be initialized. < 0 return value indicates an error. - - When the :c:type:`uv_connection_cb` callback is called it is guaranteed that - this function will complete successfully the first time. If you attempt to use - it more than once, it may fail. It is suggested to only call this function once - per :c:type:`uv_connection_cb` call. - - .. note:: - `server` and `client` must be handles running on the same loop. - -.. c:function:: int uv_read_start(uv_stream_t* stream, uv_alloc_cb alloc_cb, uv_read_cb read_cb) - - Read data from an incoming stream. The :c:type:`uv_read_cb` callback will - be made several times until there is no more data to read or - :c:func:`uv_read_stop` is called. - -.. c:function:: int uv_read_stop(uv_stream_t*) - - Stop reading data from the stream. The :c:type:`uv_read_cb` callback will - no longer be called. - - This function is idempotent and may be safely called on a stopped stream. - -.. c:function:: int uv_write(uv_write_t* req, uv_stream_t* handle, const uv_buf_t bufs[], unsigned int nbufs, uv_write_cb cb) - - Write data to stream. Buffers are written in order. Example: - - :: - - void cb(uv_write_t* req, int status) { - /* Logic which handles the write result */ - } - - uv_buf_t a[] = { - { .base = "1", .len = 1 }, - { .base = "2", .len = 1 } - }; - - uv_buf_t b[] = { - { .base = "3", .len = 1 }, - { .base = "4", .len = 1 } - }; - - uv_write_t req1; - uv_write_t req2; - - /* writes "1234" */ - uv_write(&req1, stream, a, 2, cb); - uv_write(&req2, stream, b, 2, cb); - - .. note:: - The memory pointed to by the buffers must remain valid until the callback gets called. - This also holds for :c:func:`uv_write2`. - -.. c:function:: int uv_write2(uv_write_t* req, uv_stream_t* handle, const uv_buf_t bufs[], unsigned int nbufs, uv_stream_t* send_handle, uv_write_cb cb) - - Extended write function for sending handles over a pipe. The pipe must be - initialized with `ipc` == 1. - - .. note:: - `send_handle` must be a TCP socket or pipe, which is a server or a connection (listening - or connected state). Bound sockets or pipes will be assumed to be servers. - -.. c:function:: int uv_try_write(uv_stream_t* handle, const uv_buf_t bufs[], unsigned int nbufs) - - Same as :c:func:`uv_write`, but won't queue a write request if it can't be - completed immediately. - - Will return either: - - * > 0: number of bytes written (can be less than the supplied buffer size). - * < 0: negative error code (``UV_EAGAIN`` is returned if no data can be sent - immediately). - -.. c:function:: int uv_is_readable(const uv_stream_t* handle) - - Returns 1 if the stream is readable, 0 otherwise. - -.. c:function:: int uv_is_writable(const uv_stream_t* handle) - - Returns 1 if the stream is writable, 0 otherwise. - -.. c:function:: int uv_stream_set_blocking(uv_stream_t* handle, int blocking) - - Enable or disable blocking mode for a stream. - - When blocking mode is enabled all writes complete synchronously. The - interface remains unchanged otherwise, e.g. completion or failure of the - operation will still be reported through a callback which is made - asynchronously. - - .. warning:: - Relying too much on this API is not recommended. It is likely to change - significantly in the future. - - Currently only works on Windows for :c:type:`uv_pipe_t` handles. - On UNIX platforms, all :c:type:`uv_stream_t` handles are supported. - - Also libuv currently makes no ordering guarantee when the blocking mode - is changed after write requests have already been submitted.
