It parses both requests and +responses. The parser is designed to be used in performance HTTP +applications. It does not make any syscalls nor allocations, it does not +buffer data, it can be interrupted at anytime. Depending on your +architecture, it only requires about 40 bytes of data per message +stream (in a web server that is per connection). + +Features: + + * No dependencies + * Handles persistent streams (keep-alive). + * Decodes chunked encoding. + * Upgrade support + * Defends against buffer overflow attacks. + +The parser extracts the following information from HTTP messages: + + * Header fields and values + * Content-Length + * Request method + * Response status code + * Transfer-Encoding + * HTTP version + * Request URL + * Message body + + +Usage +----- + +One `http_parser` object is used per TCP connection. Initialize the struct +using `http_parser_init()` and set the callbacks. That might look something +like this for a request parser: +```c +http_parser_settings settings; +settings.on_url = my_url_callback; +settings.on_header_field = my_header_field_callback; +/* ... */ + +http_parser *parser = malloc(sizeof(http_parser)); +http_parser_init(parser, HTTP_REQUEST); +parser->data = my_socket; +``` + +When data is received on the socket execute the parser and check for errors. + +```c +size_t len = 80*1024, nparsed; +char buf[len]; +ssize_t recved; + +recved = recv(fd, buf, len, 0); + +if (recved < 0) { + /* Handle error. */ +} + +/* Start up / continue the parser. + * Note we pass recved==0 to signal that EOF has been received. + */ +nparsed = http_parser_execute(parser, &settings, buf, recved); + +if (parser->upgrade) { + /* handle new protocol */ +} else if (nparsed != recved) { + /* Handle error. Usually just close the connection. */ +} +``` + +HTTP needs to know where the end of the stream is. For example, sometimes +servers send responses without Content-Length and expect the client to +consume input (for the body) until EOF. To tell http_parser about EOF, give +`0` as the fourth parameter to `http_parser_execute()`. Callbacks and errors +can still be encountered during an EOF, so one must still be prepared +to receive them. + +Scalar valued message information such as `status_code`, `method`, and the +HTTP version are stored in the parser structure. This data is only +temporally stored in `http_parser` and gets reset on each new message. If +this information is needed later, copy it out of the structure during the +`headers_complete` callback. + +The parser decodes the transfer-encoding for both requests and responses +transparently. That is, a chunked encoding is decoded before being sent to +the on_body callback. + + +The Special Problem of Upgrade +------------------------------ + +HTTP supports upgrading the connection to a different protocol. An +increasingly common example of this is the WebSocket protocol which sends +a request like + + GET /demo HTTP/1.1 + Upgrade: WebSocket + Connection: Upgrade + Host: example.com + Origin: http://example.com + WebSocket-Protocol: sample + +followed by non-HTTP data. + +(See [RFC6455](https://tools.ietf.org/html/rfc6455) for more information the +WebSocket protocol.) + +To support this, the parser will treat this as a normal HTTP message without a +body, issuing both on_headers_complete and on_message_complete callbacks. However +http_parser_execute() will stop parsing at the end of the headers and return. + +The user is expected to check if `parser->upgrade` has been set to 1 after +`http_parser_execute()` returns. Non-HTTP data begins at the buffer supplied +offset by the return value of `http_parser_execute()`. + + +Callbacks +--------- + +During the `http_parser_execute()` call, the callbacks set in +`http_parser_settings` will be executed. The parser maintains state and +never looks behind, so buffering the data is not necessary. If you need to +save certain data for later usage, you can do that from the callbacks. + +There are two types of callbacks: + +* notification `typedef int (*http_cb) (http_parser*);` + Callbacks: on_message_begin, on_headers_complete, on_message_complete. +* data `typedef int (*http_data_cb) (http_parser*, const char *at, size_t length);` + Callbacks: (requests only) on_url, + (common) on_header_field, on_header_value, on_body; + +Callbacks must return 0 on success. Returning a non-zero value indicates +error to the parser, making it exit immediately. + +For cases where it is necessary to pass local information to/from a callback, +the `http_parser` object's `data` field can be used. +An example of such a case is when using threads to handle a socket connection, +parse a request, and then give a response over that socket. By instantiation +of a thread-local struct containing relevant data (e.g. accepted socket, +allocated memory for callbacks to write into, etc), a parser's callbacks are +able to communicate data between the scope of the thread and the scope of the +callback in a threadsafe manner. This allows http-parser to be used in +multi-threaded contexts. + +Example: +```c + typedef struct { + socket_t sock; + void* buffer; + int buf_len; + } custom_data_t; + + +int my_url_callback(http_parser* parser, const char *at, size_t length) { + /* access to thread local custom_data_t struct. + Use this access save parsed data for later use into thread local + buffer, or communicate over socket + */ + parser->data; + ... + return 0; +} + +... + +void http_parser_thread(socket_t sock) { + int nparsed = 0; + /* allocate memory for user data */ + custom_data_t *my_data = malloc(sizeof(custom_data_t)); + + /* some information for use by callbacks. + * achieves thread -> callback information flow */ + my_data->sock = sock; + + /* instantiate a thread-local parser */ + http_parser *parser = malloc(sizeof(http_parser)); + http_parser_init(parser, HTTP_REQUEST); /* initialise parser */ + /* this custom data reference is accessible through the reference to the + parser supplied to callback functions */ + parser->data = my_data; + + http_parser_settings settings; /* set up callbacks */ + settings.on_url = my_url_callback; + + /* execute parser */ + nparsed = http_parser_execute(parser, &settings, buf, recved); + + ... + /* parsed information copied from callback. + can now perform action on data copied into thread-local memory from callbacks. + achieves callback -> thread information flow */ + my_data->buffer; + ... +} + +``` + +In case you parse HTTP message in chunks (i.e. `read()` request line +from socket, parse, read half headers, parse, etc) your data callbacks +may be called more than once. Http-parser guarantees that data pointer is only +valid for the lifetime of callback. You can also `read()` into a heap allocated +buffer to avoid copying memory around if this fits your application. + +Reading headers may be a tricky task if you read/parse headers partially. +Basically, you need to remember whether last header callback was field or value +and apply the following logic: + + (on_header_field and on_header_value shortened to on_h_*) + ------------------------ ------------ -------------------------------------------- + | State (prev. callback) | Callback | Description/action | + ------------------------ ------------ -------------------------------------------- + | nothing (first call) | on_h_field | Allocate new buffer and copy callback data | + | | | into it | + ------------------------ ------------ -------------------------------------------- + | value | on_h_field | New header started. | + | | | Copy current name,value buffers to headers | + | | | list and allocate new buffer for new name | + ------------------------ ------------ -------------------------------------------- + | field | on_h_field | Previous name continues.

Better + be overfenced than underprotected. + - ev_run now returns a boolean status (true meaning watchers are + still active). + - ev_once: undef EV_ERROR in ev_kqueue.c, to avoid clashing with + libev's EV_ERROR (reported by 191919). + - (ecb) add memory fence support for xlC (Darin McBride). + - (ecb) add memory fence support for gcc-mips (Anton Kirilov). + - (ecb) add memory fence support for gcc-alpha (Christian Weisgerber). + - work around some kernels losing file descriptors by leaking + the kqueue descriptor in the child. + - work around linux inotify not reporting IN_ATTRIB changes for directories + in many cases. + - include sys/syscall.h instead of plain syscall.h. + - check for io watcher loops in ev_verify, check for the most + common reported usage bug in ev_io_start. + - choose socket vs. WSASocket at compiletime using EV_USE_WSASOCKET. + - always use WSASend/WSARecv directly on windows, hoping that this + works in all cases (unlike read/write/send/recv...). + - try to detect signals around a fork faster (test program by + Denis Bilenko). + - work around recent glibc versions that leak memory in realloc. + - rename ev::embed::set to ev::embed::set_embed to avoid clashing + the watcher base set (loop) method. + - rewrite the async/signal pipe logic to always keep a valid fd, which + simplifies (and hopefully correctifies :) the race checking + on fork, at the cost of one extra fd. + - add fat, msdos, jffs2, ramfs, ntfs and btrfs to the list of + inotify-supporting filesystems. + - move orig_CFLAGS assignment to after AC_INIT, as newer autoconf + versions ignore it before + (https://bugzilla.redhat.com/show_bug.cgi?id=908096). + - add some untested android support. + - enum expressions must be of type int (reported by Juan Pablo L). + +4.11 Sat Feb 4 19:52:39 CET 2012 + - INCOMPATIBLE CHANGE: ev_timer_again now clears the pending status, as + was documented already, but not implemented in the repeating case. + - new compiletime symbols: EV_NO_SMP and EV_NO_THREADS. + - fix a race where the workaround against the epoll fork bugs + caused signals to not be handled anymore. + - correct backend_fudge for most backends, and implement a windows + specific workaround to avoid looping because we call both + select and Sleep, both with different time resolutions. + - document range and guarantees of ev_sleep. + - document reasonable ranges for periodics interval and offset. + - rename backend_fudge to backend_mintime to avoid future confusion :) + - change the default periodic reschedule function to hopefully be more + exact and correct even in corner cases or in the far future. + - do not rely on -lm anymore: use it when available but use our + own floor () if it is missing. This should make it easier to embed, + as no external libraries are required. + - strategically import macros from libecb and mark rarely-used functions + as cache-cold (saving almost 2k code size on typical amd64 setups). + - add Symbols.ev and Symbols.event files, that were missing. + - fix backend_mintime value for epoll (was 1/1024, is 1/1000 now). + - fix #3 "be smart about timeouts" to not "deadlock" when + timeout == now, also improve the section overall. + - avoid "AVOIDING FINISHING BEFORE RETURNING" idiom. + - support new EV_API_STATIC mode to make all libev symbols + static. + - supply default CFLAGS of -g -O3 with gcc when original CFLAGS + were empty. + +4.04 Wed Feb 16 09:01:51 CET 2011 + - fix two problems in the native win32 backend, where reuse of fd's + with different underlying handles caused handles not to be removed + or added to the select set (analyzed and tested by Bert Belder). + - do no rely on ceil() in ev_e?poll.c. + - backport libev to HP-UX versions before 11 v3. + - configure did not detect nanosleep and clock_gettime properly when + they are available in the libc (as opposed to -lrt). + +4.03 Tue Jan 11 14:37:25 CET 2011 + - officially support polling files with all backends. + - support files, /dev/zero etc. the same way as select in the epoll + backend, by generating events on our own. + - ports backend: work around solaris bug 6874410 and many related ones + (EINTR, maybe more), with no performance loss (note that the solaris + bug report is actually wrong, reality is far more bizarre and broken + than that). + - define EV_READ/EV_WRITE as macros in event.h, as some programs use + #ifdef to test for them. + - new (experimental) function: ev_feed_signal. + - new (to become default) EVFLAG_NOSIGMASK flag. + - new EVBACKEND_MASK symbol. + - updated COMMON IDIOMS SECTION. + +4.01 Fri Nov 5 21:51:29 CET 2010 + - automake fucked it up, apparently, --add-missing -f is not quite enough + to make it update its files, so 4.00 didn't install ev++.h and + event.h on make install. grrr. + - ev_loop(count|depth) didn't return anything (Robin Haberkorn). + - change EV_UNDEF to 0xffffffff to silence some overzealous compilers. + - use "(libev) " prefix for all libev error messages now. + +4.00 Mon Oct 25 12:32:12 CEST 2010 + - "PORTING FROM LIBEV 3.X TO 4.X" (in ev.pod) is recommended reading. + - ev_embed_stop did not correctly stop the watcher (very good + testcase by Vladimir Timofeev). + - ev_run will now always update the current loop time - it erroneously + didn't when idle watchers were active, causing timers not to fire. + - fix a bug where a timeout of zero caused the timer not to fire + in the libevent emulation (testcase by Péter Szabó). + - applied win32 fixes by Michael Lenaghan (also James Mansion). + - replace EV_MINIMAL by EV_FEATURES. + - prefer EPOLL_CTL_ADD over EPOLL_CTL_MOD in some more cases, as it + seems the former is *much* faster than the latter. + - linux kernel version detection (for inotify bug workarounds) + did not work properly. + - reduce the number of spurious wake-ups with the ports backend. + - remove dependency on sys/queue.h on freebsd (patch by Vanilla Hsu). + - do async init within ev_async_start, not ev_async_set, which avoids + an API quirk where the set function must be called in the C++ API + even when there is nothing to set. + - add (undocumented) EV_ENABLE when adding events with kqueue, + this might help with OS X, which seems to need it despite documenting + not to need it (helpfully pointed out by Tilghman Lesher). + - do not use poll by default on freebsd, it's broken (what isn't + on freebsd...). + - allow to embed epoll on kernels >= 2.6.32. + - configure now prepends -O3, not appends it, so one can still + override it. + - ev.pod: greatly expanded the portability section, added a porting + section, a description of watcher states and made lots of minor fixes. + - disable poll backend on AIX, the poll header spams the namespace + and it's not worth working around dead platforms (reported + and analyzed by Aivars Kalvans). + - improve header file compatibility of the standalone eventfd code + in an obscure case. + - implement EV_AVOID_STDIO option. + - do not use sscanf to parse linux version number (smaller, faster, + no sscanf dependency). + - new EV_CHILD_ENABLE and EV_SIGNAL_ENABLE configurable settings. + - update libev.m4 HAVE_CLOCK_SYSCALL test for newer glibcs. + - add section on accept() problems to the manpage. + - rename EV_TIMEOUT to EV_TIMER. + - rename ev_loop_count/depth/verify/loop/unloop. + - remove ev_default_destroy and ev_default_fork. + - switch to two-digit minor version. + - work around an apparent gentoo compiler bug. + - define _DARWIN_UNLIMITED_SELECT. just so. + - use enum instead of #define for most constants. + - improve compatibility to older C++ compilers. + - (experimental) ev_run/ev_default_loop/ev_break/ev_loop_new have now + default arguments when compiled as C++. + - enable automake dependency tracking. + - ev_loop_new no longer leaks memory when loop creation failed. + - new ev_cleanup watcher type. + +3.9 Thu Dec 31 07:59:59 CET 2009 + - signalfd is no longer used by default and has to be requested + explicitly - this means that easy to catch bugs become hard to + catch race conditions, but the users have spoken. + - point out the unspecified signal mask in the documentation, and + that this is a race condition regardless of EV_SIGNALFD. + - backport inotify code to C89. + - inotify file descriptors could leak into child processes. + - ev_stat watchers could keep an erroneous extra ref on the loop, + preventing exit when unregistering all watchers (testcases + provided by ry@tinyclouds.org). + - implement EV_WIN32_HANDLE_TO_FD and EV_WIN32_CLOSE_FD configuration + symbols to make it easier for apps to do their own fd management. + - support EV_IDLE_ENABLE being disabled in ev++.h + (patch by Didier Spezia). + - take advantage of inotify_init1, if available, to set cloexec/nonblock + on fd creation, to avoid races. + - the signal handling pipe wasn't always initialised under windows + (analysed by lekma). + - changed minimum glibc requirement from glibc 2.9 to 2.7, for + signalfd. + - add missing string.h include (Denis F. Latypoff). + - only replace ev_stat.prev when we detect an actual difference, + so prev is (almost) always different to attr. this might + have caused the problems with 04_stat.t. + - add ev::timer->remaining () method to C++ API. + +3.8 Sun Aug 9 14:30:45 CEST 2009 + - incompatible change: do not necessarily reset signal handler + to SIG_DFL when a sighandler is stopped. + - ev_default_destroy did not properly free or zero some members, + potentially causing crashes and memory corruption on repeated + ev_default_destroy/ev_default_loop calls. + - take advantage of signalfd on GNU/Linux systems. + - document that the signal mask might be in an unspecified + state when using libev's signal handling. + - take advantage of some GNU/Linux calls to set cloexec/nonblock + on fd creation, to avoid race conditions. + +3.7 Fri Jul 17 16:36:32 CEST 2009 + - ev_unloop and ev_loop wrongly used a global variable to exit loops, + instead of using a per-loop variable (bug caught by accident...). + - the ev_set_io_collect_interval interpretation has changed. + - add new functionality: ev_set_userdata, ev_userdata, + ev_set_invoke_pending_cb, ev_set_loop_release_cb, + ev_invoke_pending, ev_pending_count, together with a long example + about thread locking. + - add ev_timer_remaining (as requested by Denis F. Latypoff). + - add ev_loop_depth. + - calling ev_unloop in fork/prepare watchers will no longer poll + for new events. + - Denis F. Latypoff corrected many typos in example code snippets. + - honor autoconf detection of EV_USE_CLOCK_SYSCALL, also double- + check that the syscall number is available before trying to + use it (reported by ry@tinyclouds). + - use GetSystemTimeAsFileTime instead of _timeb on windows, for + slightly higher accuracy. + - properly declare ev_loop_verify and ev_now_update even when + !EV_MULTIPLICITY. + - do not compile in any priority code when EV_MAXPRI == EV_MINPRI. + - support EV_MINIMAL==2 for a reduced API. + - actually 0-initialise struct sigaction when installing signals. + - add section on hibernate and stopped processes to ev_timer docs. + +3.6 Tue Apr 28 02:49:30 CEST 2009 + - multiple timers becoming ready within an event loop iteration + will be invoked in the "correct" order now. + - do not leave the event loop early just because we have no active + watchers, fixing a problem when embedding a kqueue loop + that has active kernel events but no registered watchers + (reported by blacksand blacksand). + - correctly zero the idx values for arrays, so destroying and + reinitialising the default loop actually works (patch by + Malek Hadj-Ali). + - implement ev_suspend and ev_resume. + - new EV_CUSTOM revents flag for use by applications. + - add documentation section about priorities. + - add a glossary to the documentation. + - extend the ev_fork description slightly. + - optimize a jump out of call_pending. + +3.53 Sun Feb 15 02:38:20 CET 2009 + - fix a bug in event pipe creation on win32 that would cause a + failed assertion on event loop creation (patch by Malek Hadj-Ali). + - probe for CLOCK_REALTIME support at runtime as well and fall + back to gettimeofday if there is an error, to support older + operating systems with newer header files/libraries. + - prefer gettimeofday over clock_gettime with USE_CLOCK_SYSCALL + (default most everywhere), otherwise not. + +3.52 Wed Jan 7 21:43:02 CET 2009 + - fix compilation of select backend in fd_set mode when NFDBITS is + missing (to get it to compile on QNX, reported by Rodrigo Campos). + - better select-nfds handling when select backend is in fd_set mode. + - diagnose fd_set overruns when select backend is in fd_set mode. + - due to a thinko, instead of disabling everything but + select on the borked OS X platform, everything but select was + allowed (reported by Emanuele Giaquinta). + - actually verify that local and remote port are matching in + libev's socketpair emulation, which makes denial-of-service + attacks harder (but not impossible - it's windows). Make sure + it even works under vista, which thinks that getpeer/sockname + should return fantasy port numbers. + - include "libev" in all assertion messages for potentially + clearer diagnostics. + - event_get_version (libevent compatibility) returned + a useless string instead of the expected version string + (patch by W.C.A.

The biggest issue is fork races, however \- if a program +forks then \fIboth\fR parent and child process have to recreate the epoll +set, which can take considerable time (one syscall per file descriptor) +and is of course hard to detect. +.Sp +Epoll is also notoriously buggy \- embedding epoll fds \fIshould\fR work, +but of course \fIdoesn't\fR, and epoll just loves to report events for +totally \fIdifferent\fR file descriptors (even already closed ones, so +one cannot even remove them from the set) than registered in the set +(especially on \s-1SMP\s0 systems). Libev tries to counter these spurious +notifications by employing an additional generation counter and comparing +that against the events to filter out spurious ones, recreating the set +when required. Epoll also erroneously rounds down timeouts, but gives you +no way to know when and by how much, so sometimes you have to busy-wait +because epoll returns immediately despite a nonzero timeout. And last +not least, it also refuses to work with some file descriptors which work +perfectly fine with \f(CW\*(C`select\*(C'\fR (files, many character devices...). +.Sp +Epoll is truly the train wreck among event poll mechanisms, a frankenpoll, +cobbled together in a hurry, no thought to design or interaction with +others.

Also, \f(CW\*(C`dup ()\*(C'\fR'ed +file descriptors might not work very well if you register events for both +file descriptors. +.Sp +Best performance from this backend is achieved by not unregistering all +watchers for a file descriptor until it has been closed, if possible, +i.e. keep at least one watcher active per fd at all times. Stopping and +starting a watcher (without re-setting it) also usually doesn't cause +extra overhead. A fork can both result in spurious notifications as well +as in libev having to destroy and recreate the epoll object, which can +take considerable time and thus should be avoided. +.Sp +All this means that, in practice, \f(CW\*(C`EVBACKEND_SELECT\*(C'\fR can be as fast or +faster than epoll for maybe up to a hundred file descriptors, depending on +the usage.

While this makes the +program responsive, it also wastes a lot of \s-1CPU\s0 time to poll for new +events, especially with backends like \f(CW\*(C`select ()\*(C'\fR which have a high +overhead for the actual polling but can deliver many events at once. +.Sp +By setting a higher \fIio collect interval\fR you allow libev to spend more +time collecting I/O events, so you can handle more events per iteration, +at the cost of increasing latency.

One way around this is to wake up the event +loop via \f(CW\*(C`ev_break\*(C'\fR and \f(CW\*(C`ev_async_send\*(C'\fR, another way is to set these +\&\fIrelease\fR and \fIacquire\fR callbacks on the loop. +.Sp +When set, then \f(CW\*(C`release\*(C'\fR will be called just before the thread is +suspended waiting for new events, and \f(CW\*(C`acquire\*(C'\fR is called just +afterwards. +.Sp +Ideally, \f(CW\*(C`release\*(C'\fR will just call your mutex_unlock function, and +\&\f(CW\*(C`acquire\*(C'\fR will just call the mutex_lock function again. +.Sp +While event loop modifications are allowed between invocations of +\&\f(CW\*(C`release\*(C'\fR and \f(CW\*(C`acquire\*(C'\fR (that's their only purpose after all), no +modifications done will affect the event loop, i.e. adding watchers will +have no effect on the set of file descriptors being watched, or the time +waited.

The +latter will clear any pending state the watcher might be in, regardless +of whether it was active or not, so stopping a watcher explicitly before +freeing it is often a good idea. +.Sp +While stopped (and not pending) the watcher is essentially in the +initialised state, that is, it can be reused, moved, modified in any way +you wish (but when you trash the memory block, you need to \f(CW\*(C`ev_TYPE_init\*(C'\fR +it again). +.SS "\s-1WATCHER PRIORITY MODELS\s0" +.IX Subsection "WATCHER PRIORITY MODELS" +Many event loops support \fIwatcher priorities\fR, which are usually small +integers that influence the ordering of event callback invocation +between watchers in some way, all else being equal. +.PP +In libev, watcher priorities can be set using \f(CW\*(C`ev_set_priority\*(C'\fR. See its +description for the more technical details such as the actual priority +range. +.PP +There are two common ways how these these priorities are being interpreted +by event loops: +.PP +In the more common lock-out model, higher priorities \*(L"lock out\*(R" invocation +of lower priority watchers, which means as long as higher priority +watchers receive events, lower priority watchers are not being invoked. +.PP +The less common only-for-ordering model uses priorities solely to order +callback invocation within a single event loop iteration: Higher priority +watchers are invoked before lower priority ones, but they all get invoked +before polling for new events. +.PP +Libev uses the second (only-for-ordering) model for all its watchers +except for idle watchers (which use the lock-out model). +.PP +The rationale behind this is that implementing the lock-out model for +watchers is not well supported by most kernel interfaces, and most event +libraries will just poll for the same events again and again as long as +their callbacks have not been executed, which is very inefficient in the +common case of one high-priority watcher locking out a mass of lower +priority ones. +.PP +Static (ordering) priorities are most useful when you have two or more +watchers handling the same resource: a typical usage example is having an +\&\f(CW\*(C`ev_io\*(C'\fR watcher to receive data, and an associated \f(CW\*(C`ev_timer\*(C'\fR to handle +timeouts. Under load, data might be received while the program handles +other jobs, but since timers normally get invoked first, the timeout +handler will be executed before checking for data. In that case, giving +the timer a lower priority than the I/O watcher ensures that I/O will be +handled first even under adverse conditions (which is usually, but not +always, what you want). +.PP +Since idle watchers use the \*(L"lock-out\*(R" model, meaning that idle watchers +will only be executed when no same or higher priority watchers have +received events, they can be used to implement the \*(L"lock-out\*(R" model when +required. +.PP +For example, to emulate how many other event libraries handle priorities, +you can associate an \f(CW\*(C`ev_idle\*(C'\fR watcher to each such watcher, and in +the normal watcher callback, you just start the idle watcher. The real +processing is done in the idle watcher callback. This causes libev to +continuously poll and process kernel event data for the watcher, but when +the lock-out case is known to be rare (which in turn is rare :), this is +workable. +.PP +Usually, however, the lock-out model implemented that way will perform +miserably under the type of load it was designed to handle. In that case, +it might be preferable to stop the real watcher before starting the +idle watcher, so the kernel will not have to process the event in case +the actual processing will be delayed for considerable time. +.PP +Here is an example of an I/O watcher that should run at a strictly lower +priority than the default, and which should only process data when no +other events are pending: +.PP +.Vb 2 +\& ev_idle idle; // actual processing watcher +\& ev_io io; // actual event watcher +\& +\& static void +\& io_cb (EV_P_ ev_io *w, int revents) +\& { +\& // stop the I/O watcher, we received the event, but +\& // are not yet ready to handle it. +\& ev_io_stop (EV_A_ w); +\& +\& // start the idle watcher to handle the actual event. +\& // it will not be executed as long as other watchers +\& // with the default priority are receiving events. +\& ev_idle_start (EV_A_ &idle); +\& } +\& +\& static void +\& idle_cb (EV_P_ ev_idle *w, int revents) +\& { +\& // actual processing +\& read (STDIN_FILENO, ...); +\& +\& // have to start the I/O watcher again, as +\& // we have handled the event +\& ev_io_start (EV_P_ &io); +\& } +\& +\& // initialisation +\& ev_idle_init (&idle, idle_cb); +\& ev_io_init (&io, io_cb, STDIN_FILENO, EV_READ); +\& ev_io_start (EV_DEFAULT_ &io); +.Ve +.PP +In the \*(L"real\*(R" world, it might also be beneficial to start a timer, so that +low-priority connections can not be locked out forever under load. This +enables your program to keep a lower latency for important connections +during short periods of high load, while not completely locking out less +important ones. +.SH "WATCHER TYPES" +.IX Header "WATCHER TYPES" +This section describes each watcher in detail, but will not repeat +information given in the last section. Any initialisation/set macros, +functions and members specific to the watcher type are explained. +.PP +Most members are additionally marked with either \fI[read\-only]\fR, meaning +that, while the watcher is active, you can look at the member and expect +some sensible content, but you must not modify it (you can modify it while +the watcher is stopped to your hearts content), or \fI[read\-write]\fR, which +means you can expect it to have some sensible content while the watcher is +active, but you can also modify it (within the same thread as the event +loop, i.e. without creating data races). Modifying it may not do something +sensible or take immediate effect (or do anything at all), but libev will +not crash or malfunction in any way. +.PP +In any case, the documentation for each member will explain what the +effects are, and if there are any additional access restrictions. +.ie n .SS """ev_io"" \- is this file descriptor readable or writable?" +.el .SS "\f(CWev_io\fP \- is this file descriptor readable or writable?" +.IX Subsection "ev_io - is this file descriptor readable or writable?" +I/O watchers check whether a file descriptor is readable or writable +in each iteration of the event loop, or, more precisely, when reading +would not block the process and writing would at least be able to write +some data. This behaviour is called level-triggering because you keep +receiving events as long as the condition persists. Remember you can stop +the watcher if you don't want to act on the event and neither want to +receive future events. +.PP +In general you can register as many read and/or write event watchers per +fd as you want (as long as you don't confuse yourself). Setting all file +descriptors to non-blocking mode is also usually a good idea (but not +required if you know what you are doing). +.PP +Another thing you have to watch out for is that it is quite easy to +receive \*(L"spurious\*(R" readiness notifications, that is, your callback might +be called with \f(CW\*(C`EV_READ\*(C'\fR but a subsequent \f(CW\*(C`read\*(C'\fR(2) will actually block +because there is no data. It is very easy to get into this situation even +with a relatively standard program structure. Thus it is best to always +use non-blocking I/O: An extra \f(CW\*(C`read\*(C'\fR(2) returning \f(CW\*(C`EAGAIN\*(C'\fR is far +preferable to a program hanging until some data arrives. +.PP +If you cannot run the fd in non-blocking mode (for example you should +not play around with an Xlib connection), then you have to separately +re-test whether a file descriptor is really ready with a known-to-be good +interface such as poll (fortunately in the case of Xlib, it already does +this on its own, so its quite safe to use). Some people additionally +use \f(CW\*(C`SIGALRM\*(C'\fR and an interval timer, just to be sure you won't block +indefinitely. +.PP +But really, best use non-blocking mode. +.PP +\fIThe special problem of disappearing file descriptors\fR +.IX Subsection "The special problem of disappearing file descriptors" +.PP +Some backends (e.g. kqueue, epoll, linuxaio) need to be told about closing +a file descriptor (either due to calling \f(CW\*(C`close\*(C'\fR explicitly or any other +means, such as \f(CW\*(C`dup2\*(C'\fR). The reason is that you register interest in some +file descriptor, but when it goes away, the operating system will silently +drop this interest. If another file descriptor with the same number then +is registered with libev, there is no efficient way to see that this is, +in fact, a different file descriptor. +.PP +To avoid having to explicitly tell libev about such cases, libev follows +the following policy: Each time \f(CW\*(C`ev_io_set\*(C'\fR is being called, libev +will assume that this is potentially a new file descriptor, otherwise +it is assumed that the file descriptor stays the same. That means that +you \fIhave\fR to call \f(CW\*(C`ev_io_set\*(C'\fR (or \f(CW\*(C`ev_io_init\*(C'\fR) when you change the +descriptor even if the file descriptor number itself did not change. +.PP +This is how one would do it normally anyway, the important point is that +the libev application should not optimise around libev but should leave +optimisations to libev. +.PP +\fIThe special problem of dup'ed file descriptors\fR +.IX Subsection "The special problem of dup'ed file descriptors" +.PP +Some backends (e.g. epoll), cannot register events for file descriptors, +but only events for the underlying file descriptions. That means when you +have \f(CW\*(C`dup ()\*(C'\fR'ed file descriptors or weirder constellations, and register +events for them, only one file descriptor might actually receive events. +.PP +There is no workaround possible except not registering events +for potentially \f(CW\*(C`dup ()\*(C'\fR'ed file descriptors, or to resort to +\&\f(CW\*(C`EVBACKEND_SELECT\*(C'\fR or \f(CW\*(C`EVBACKEND_POLL\*(C'\fR. +.PP +\fIThe special problem of files\fR +.IX Subsection "The special problem of files" +.PP +Many people try to use \f(CW\*(C`select\*(C'\fR (or libev) on file descriptors +representing files, and expect it to become ready when their program +doesn't block on disk accesses (which can take a long time on their own). +.PP +However, this cannot ever work in the \*(L"expected\*(R" way \- you get a readiness +notification as soon as the kernel knows whether and how much data is +there, and in the case of open files, that's always the case, so you +always get a readiness notification instantly, and your read (or possibly +write) will still block on the disk I/O. +.PP +Another way to view it is that in the case of sockets, pipes, character +devices and so on, there is another party (the sender) that delivers data +on its own, but in the case of files, there is no such thing: the disk +will not send data on its own, simply because it doesn't know what you +wish to read \- you would first have to request some data. +.PP +Since files are typically not-so-well supported by advanced notification +mechanism, libev tries hard to emulate \s-1POSIX\s0 behaviour with respect +to files, even though you should not use it. The reason for this is +convenience: sometimes you want to watch \s-1STDIN\s0 or \s-1STDOUT,\s0 which is +usually a tty, often a pipe, but also sometimes files or special devices +(for example, \f(CW\*(C`epoll\*(C'\fR on Linux works with \fI/dev/random\fR but not with +\&\fI/dev/urandom\fR), and even though the file might better be served with +asynchronous I/O instead of with non-blocking I/O, it is still useful when +it \*(L"just works\*(R" instead of freezing. +.PP +So avoid file descriptors pointing to files when you know it (e.g. use +libeio), but use them when it is convenient, e.g. for \s-1STDIN/STDOUT,\s0 or +when you rarely read from a file instead of from a socket, and want to +reuse the same code path. +.PP +\fIThe special problem of fork\fR +.IX Subsection "The special problem of fork" +.PP +Some backends (epoll, kqueue, linuxaio, iouring) do not support \f(CW\*(C`fork ()\*(C'\fR +at all or exhibit useless behaviour. Libev fully supports fork, but needs +to be told about it in the child if you want to continue to use it in the +child. +.PP +To support fork in your child processes, you have to call \f(CW\*(C`ev_loop_fork +()\*(C'\fR after a fork in the child, enable \f(CW\*(C`EVFLAG_FORKCHECK\*(C'\fR, or resort to +\&\f(CW\*(C`EVBACKEND_SELECT\*(C'\fR or \f(CW\*(C`EVBACKEND_POLL\*(C'\fR. +.PP +\fIThe special problem of \s-1SIGPIPE\s0\fR +.IX Subsection "The special problem of SIGPIPE" +.PP +While not really specific to libev, it is easy to forget about \f(CW\*(C`SIGPIPE\*(C'\fR: +when writing to a pipe whose other end has been closed, your program gets +sent a \s-1SIGPIPE,\s0 which, by default, aborts your program. For most programs +this is sensible behaviour, for daemons, this is usually undesirable. +.PP +So when you encounter spurious, unexplained daemon exits, make sure you +ignore \s-1SIGPIPE\s0 (and maybe make sure you log the exit status of your daemon +somewhere, as that would have given you a big clue). +.PP +\fIThe special problem of \f(BIaccept()\fIing when you can't\fR +.IX Subsection "The special problem of accept()ing when you can't" +.PP +Many implementations of the \s-1POSIX\s0 \f(CW\*(C`accept\*(C'\fR function (for example, +found in post\-2004 Linux) have the peculiar behaviour of not removing a +connection from the pending queue in all error cases. +.PP +For example, larger servers often run out of file descriptors (because +of resource limits), causing \f(CW\*(C`accept\*(C'\fR to fail with \f(CW\*(C`ENFILE\*(C'\fR but not +rejecting the connection, leading to libev signalling readiness on +the next iteration again (the connection still exists after all), and +typically causing the program to loop at 100% \s-1CPU\s0 usage. +.PP +Unfortunately, the set of errors that cause this issue differs between +operating systems, there is usually little the app can do to remedy the +situation, and no known thread-safe method of removing the connection to +cope with overload is known (to me). +.PP +One of the easiest ways to handle this situation is to just ignore it +\&\- when the program encounters an overload, it will just loop until the +situation is over. While this is a form of busy waiting, no \s-1OS\s0 offers an +event-based way to handle this situation, so it's the best one can do. +.PP +A better way to handle the situation is to log any errors other than +\&\f(CW\*(C`EAGAIN\*(C'\fR and \f(CW\*(C`EWOULDBLOCK\*(C'\fR, making sure not to flood the log with such +messages, and continue as usual, which at least gives the user an idea of +what could be wrong (\*(L"raise the ulimit!\*(R"). For extra points one could stop +the \f(CW\*(C`ev_io\*(C'\fR watcher on the listening fd \*(L"for a while\*(R", which reduces \s-1CPU\s0 +usage. +.PP +If your program is single-threaded, then you could also keep a dummy file +descriptor for overload situations (e.g. by opening \fI/dev/null\fR), and +when you run into \f(CW\*(C`ENFILE\*(C'\fR or \f(CW\*(C`EMFILE\*(C'\fR, close it, run \f(CW\*(C`accept\*(C'\fR, +close that fd, and create a new dummy fd. This will gracefully refuse +clients under typical overload conditions. +.PP +The last way to handle it is to simply log the error and \f(CW\*(C`exit\*(C'\fR, as +is often done with \f(CW\*(C`malloc\*(C'\fR failures, but this results in an easy +opportunity for a DoS attack. +.PP +\fIWatcher-Specific Functions\fR +.IX Subsection "Watcher-Specific Functions" +.IP "ev_io_init (ev_io *, callback, int fd, int events)" 4 +.IX Item "ev_io_init (ev_io *, callback, int fd, int events)" +.PD 0 +.IP "ev_io_set (ev_io *, int fd, int events)" 4 +.IX Item "ev_io_set (ev_io *, int fd, int events)" +.PD +Configures an \f(CW\*(C`ev_io\*(C'\fR watcher.

Less obviously, it cannot be +guaranteed to any precision by libev \- imagine somebody suspending the +process with a \s-1STOP\s0 signal for a few hours for example. +.PP +So, libev tries to invoke your callback as soon as possible \fIafter\fR the +delay has occurred, but cannot guarantee this. +.PP +A less obvious failure mode is calling your callback too early: many event +loops compare timestamps with a \*(L"elapsed delay >= requested delay\*(R", but +this can cause your callback to be invoked much earlier than you would +expect. +.PP +To see why, imagine a system with a clock that only offers full second +resolution (think windows if you can't come up with a broken enough \s-1OS\s0 +yourself). If you schedule a one-second timer at the time 500.9, then the +event loop will schedule your timeout to elapse at a system time of 500 +(500.9 truncated to the resolution) + 1, or 501. +.PP +If an event library looks at the timeout 0.1s later, it will see \*(L"501 >= +501\*(R" and invoke the callback 0.1s after it was started, even though a +one-second delay was requested \- this is being \*(L"too early\*(R", despite best +intentions. +.PP +This is the reason why libev will never invoke the callback if the elapsed +delay equals the requested delay, but only when the elapsed delay is +larger than the requested delay. In the example above, libev would only invoke +the callback at system time 502, or 1.1s after the timer was started. +.PP +So, while libev cannot guarantee that your callback will be invoked +exactly when requested, it \fIcan\fR and \fIdoes\fR guarantee that the requested +delay has actually elapsed, or in other words, it always errs on the \*(L"too +late\*(R" side of things. +.PP +\fIThe special problem of time updates\fR +.IX Subsection "The special problem of time updates" +.PP +Establishing the current time is a costly operation (it usually takes +at least one system call): \s-1EV\s0 therefore updates its idea of the current +time only before and after \f(CW\*(C`ev_run\*(C'\fR collects new events, which causes a +growing difference between \f(CW\*(C`ev_now ()\*(C'\fR and \f(CW\*(C`ev_time ()\*(C'\fR when handling +lots of events in one iteration. +.PP +The relative timeouts are calculated relative to the \f(CW\*(C`ev_now ()\*(C'\fR +time. This is usually the right thing as this timestamp refers to the time +of the event triggering whatever timeout you are modifying/starting.

On a GNU/Linux system, for example, +a call to \f(CW\*(C`gettimeofday\*(C'\fR might return a second count that is one higher +than a directly following call to \f(CW\*(C`time\*(C'\fR. +.PP +The moral of this is to only compare libev-related timestamps with +\&\f(CW\*(C`ev_time ()\*(C'\fR and \f(CW\*(C`ev_now ()\*(C'\fR, at least if you want better precision than +a second or so. +.PP +One more problem arises due to this lack of synchronisation: if libev uses +the system monotonic clock and you compare timestamps from \f(CW\*(C`ev_time\*(C'\fR +or \f(CW\*(C`ev_now\*(C'\fR from when you started your timer and when your callback is +invoked, you will find that sometimes the callback is a bit \*(L"early\*(R". +.PP +This is because \f(CW\*(C`ev_timer\*(C'\fRs work in real time, not wall clock time, so +libev makes sure your callback is not invoked before the delay happened, +\&\fImeasured according to the real time\fR, not the system clock. +.PP +If your timeouts are based on a physical timescale (e.g. \*(L"time out this +connection after 100 seconds\*(R") then this shouldn't bother you as it is +exactly the right behaviour. +.PP +If you want to compare wall clock/system timestamps to your timers, then +you need to use \f(CW\*(C`ev_periodic\*(C'\fRs, as these are based on the wall clock +time, where your comparisons will always generate correct results. +.PP +\fIThe special problems of suspended animation\fR +.IX Subsection "The special problems of suspended animation" +.PP +When you leave the server world it is quite customary to hit machines that +can suspend/hibernate \- what happens to the clocks during such a suspend? +.PP +Some quick tests made with a Linux 2.6.28 indicate that a suspend freezes +all processes, while the clocks (\f(CW\*(C`times\*(C'\fR, \f(CW\*(C`CLOCK_MONOTONIC\*(C'\fR) continue +to run until the system is suspended, but they will not advance while the +system is suspended. That means, on resume, it will be as if the program +was frozen for a few seconds, but the suspend time will not be counted +towards \f(CW\*(C`ev_timer\*(C'\fR when a monotonic clock source is used.

Libev still offers limited functionality on this platform in +the form of the \f(CW\*(C`EVBACKEND_SELECT\*(C'\fR backend, and only supports socket +descriptors. This only applies when using Win32 natively, not when using +e.g. cygwin. Actually, it only applies to the microsofts own compilers, +as every compiler comes with a slightly differently broken/incompatible +environment. +.PP +Lifting these limitations would basically require the full +re-implementation of the I/O system. If you are into this kind of thing, +then note that glib does exactly that for you in a very portable way (note +also that glib is the slowest event library known to man). +.PP +There is no supported compilation method available on windows except +embedding it into other applications. +.PP +Sensible signal handling is officially unsupported by Microsoft \- libev +tries its best, but under most conditions, signals will simply not work. +.PP +Not a libev limitation but worth mentioning: windows apparently doesn't +accept large writes: instead of resulting in a partial write, windows will +either accept everything or return \f(CW\*(C`ENOBUFS\*(C'\fR if the buffer is too large, +so make sure you only write small amounts into your sockets (less than a +megabyte seems safe, but this apparently depends on the amount of memory +available). +.PP +Due to the many, low, and arbitrary limits on the win32 platform and +the abysmal performance of winsockets, using a large number of sockets +is not recommended (and not reasonable). If your program needs to use +more than a hundred or so sockets, then likely it needs to use a totally +different implementation for windows, as libev offers the \s-1POSIX\s0 readiness +notification model, which cannot be implemented efficiently on windows +(due to Microsoft monopoly games). +.PP +A typical way to use libev under windows is to embed it (see the embedding +section for details) and use the following \fIevwrap.h\fR header file instead +of \fIev.h\fR: +.PP +.Vb 2 +\& #define EV_STANDALONE /* keeps ev from requiring config.h */ +\& #define EV_SELECT_IS_WINSOCKET 1 /* configure libev for windows select */ +\& +\& #include "ev.h" +.Ve +.PP +And compile the following \fIevwrap.c\fR file into your project (make sure +you do \fInot\fR compile the \fIev.c\fR or any other embedded source files!): +.PP +.Vb 2 +\& #include "evwrap.h" +\& #include "ev.c" +.Ve +.PP +\fIThe winsocket \f(CI\*(C`select\*(C'\fI function\fR +.IX Subsection "The winsocket select function" +.PP +The winsocket \f(CW\*(C`select\*(C'\fR function doesn't follow \s-1POSIX\s0 in that it +requires socket \fIhandles\fR and not socket \fIfile descriptors\fR (it is +also extremely buggy). This makes select very inefficient, and also +requires a mapping from file descriptors to socket handles (the Microsoft +C runtime provides the function \f(CW\*(C`_open_osfhandle\*(C'\fR for this).

Sounds great!). +.PP +Newer versions support more handles, but you need to define \f(CW\*(C`FD_SETSIZE\*(C'\fR +to some high number (e.g. \f(CW2048\fR) before compiling the winsocket select +call (which might be in libev or elsewhere, for example, perl and many +other interpreters do their own select emulation on windows). +.PP +Another limit is the number of file descriptors in the Microsoft runtime +libraries, which by default is \f(CW64\fR (there must be a hidden \fI64\fR +fetish or something like this inside Microsoft). You can increase this +by calling \f(CW\*(C`_setmaxstdio\*(C'\fR, which can increase this limit to \f(CW2048\fR +(another arbitrary limit), but is broken in many versions of the Microsoft +runtime libraries. This might get you to about \f(CW512\fR or \f(CW2048\fR sockets +(depending on windows version and/or the phase of the moon). To get more, +you need to wrap all I/O functions and provide your own fd management, but +the cost of calling select (O(nX)) will likely make this unworkable. +.SS "\s-1PORTABILITY REQUIREMENTS\s0" +.IX Subsection "PORTABILITY REQUIREMENTS" +In addition to a working ISO-C implementation and of course the +backend-specific APIs, libev relies on a few additional extensions: +.ie n .IP """void (*)(ev_watcher_type *, int revents)"" must have compatible calling conventions regardless of ""ev_watcher_type *""." 4 +.el .IP "\f(CWvoid (*)(ev_watcher_type *, int revents)\fR must have compatible calling conventions regardless of \f(CWev_watcher_type *\fR." 4 +.IX Item "void (*)(ev_watcher_type *, int revents) must have compatible calling conventions regardless of ev_watcher_type *." +Libev assumes not only that all watcher pointers have the same internal +structure (guaranteed by \s-1POSIX\s0 but not by \s-1ISO C\s0 for example), but it also +assumes that the same (machine) code can be used to call any watcher +callback: The watcher callbacks have different type signatures, but libev +calls them using an \f(CW\*(C`ev_watcher *\*(C'\fR internally. +.IP "null pointers and integer zero are represented by 0 bytes" 4 +.IX Item "null pointers and integer zero are represented by 0 bytes" +Libev uses \f(CW\*(C`memset\*(C'\fR to initialise structs and arrays to \f(CW0\fR bytes, and +relies on this setting pointers and integers to null. +.IP "pointer accesses must be thread-atomic" 4 +.IX Item "pointer accesses must be thread-atomic" +Accessing a pointer value must be atomic, it must both be readable and +writable in one piece \- this is the case on all current architectures. +.ie n .IP """sig_atomic_t volatile"" must be thread-atomic as well" 4 +.el .IP "\f(CWsig_atomic_t volatile\fR must be thread-atomic as well" 4 +.IX Item "sig_atomic_t volatile must be thread-atomic as well" +The type \f(CW\*(C`sig_atomic_t volatile\*(C'\fR (or whatever is defined as +\&\f(CW\*(C`EV_ATOMIC_T\*(C'\fR) must be atomic with respect to accesses from different +threads.

If you just want to know the basics of libev, I suggest +reading L, then the L above and +look up the missing functions in L and the C and +C sections in L. + +=head1 ABOUT LIBEV + +Libev is an event loop: you register interest in certain events (such as a +file descriptor being readable or a timeout occurring), and it will manage +these event sources and provide your program with events. + +To do this, it must take more or less complete control over your process +(or thread) by executing the I handler, and will then +communicate events via a callback mechanism. + +You register interest in certain events by registering so-called I, which are relatively small C structures you initialise with the +details of the event, and then hand it over to libev by I the +watcher. + +=head2 FEATURES + +Libev supports C (files, many character devices...). + +Epoll is truly the train wreck among event poll mechanisms, a frankenpoll, +cobbled together in a hurry, no thought to design or interaction with +others. Oh, the pain, will it ever stop... + +While stopping, setting and starting an I/O watcher in the same iteration +will result in some caching, there is still a system call per such +incident (because the same I could point to a different +I now), so its best to avoid that. Also, C'ed +file descriptors might not work very well if you register events for both +file descriptors. + +Best performance from this backend is achieved by not unregistering all +watchers for a file descriptor until it has been closed, if possible, +i.e. keep at least one watcher active per fd at all times. Stopping and +starting a watcher (without re-setting it) also usually doesn't cause +extra overhead. A fork can both result in spurious notifications as well +as in libev having to destroy and recreate the epoll object, which can +take considerable time and thus should be avoided. + +All this means that, in practice, C can be as fast or +faster than epoll for maybe up to a hundred file descriptors, depending on +the usage. So sad. + +While nominally embeddable in other event loops, this feature is broken in +a lot of kernel revisions, but probably(!) works in current versions. + +This backend maps C and C in the same way as +C. + +=item C (value 64, Linux) + +Use the Linux-specific Linux AIO (I C<< aio(7) >> but C<< +io_submit(2) >>) event interface available in post-4.18 kernels (but libev +only tries to use it in 4.19+). + +This is another Linux train wreck of an event interface. + +If this backend works for you (as of this writing, it was very +experimental), it is the best event interface available on Linux and might +be well worth enabling it - if it isn't available in your kernel this will +be detected and this backend will be skipped. + +This backend can batch oneshot requests and supports a user-space ring +buffer to receive events. It also doesn't suffer from most of the design +problems of epoll (such as not being able to remove event sources from +the epoll set), and generally sounds too good to be true. Because, this +being the Linux kernel, of course it suffers from a whole new set of +limitations, forcing you to fall back to epoll, inheriting all its design +issues. + +For one, it is not easily embeddable (but probably could be done using +an event fd at some extra overhead). It also is subject to a system wide +limit that can be configured in F. If no AIO +requests are left, this backend will be skipped during initialisation, and +will switch to epoll when the loop is active. + +Most problematic in practice, however, is that not all file descriptors +work with it. For example, in Linux 5.1, TCP sockets, pipes, event fds, +files, F and many others are supported, but ttys do not work +properly (a known bug that the kernel developers don't care about, see +L), so this is not +(yet?) a generic event polling interface. + +Overall, it seems the Linux developers just don't want it to have a +generic event handling mechanism other than C which have a high +overhead for the actual polling but can deliver many events at once. + +By setting a higher I you allow libev to spend more +time collecting I/O events, so you can handle more events per iteration, +at the cost of increasing latency. Timeouts (both C and +C) will not be affected. Setting this to a non-null value will +introduce an additional C call into most loop iterations. The +sleep time ensures that libev will not poll for I/O events more often then +once per this interval, on average (as long as the host time resolution is +good enough). + +Likewise, by setting a higher I you allow libev +to spend more time collecting timeouts, at the expense of increased +latency/jitter/inexactness (the watcher callback will be called +later). C watchers will not be affected. Setting this to a non-null +value will not introduce any overhead in libev. + +Many (busy) programs can usually benefit by setting the I/O collect +interval to a value near C<0.1> or so, which is often enough for +interactive servers (of course not for games), likewise for timeouts. It +usually doesn't make much sense to set it to a lower value than C<0.01>, +as this approaches the timing granularity of most systems. Note that if +you do transactions with the outside world and you can't increase the +parallelity, then this setting will limit your transaction rate (if you +need to poll once per transaction and the I/O collect interval is 0.01, +then you can't do more than 100 transactions per second). + +Setting the I can improve the opportunity for +saving power, as the program will "bundle" timer callback invocations that +are "near" in time together, by delaying some, thus reducing the number of +times the process sleeps and wakes up again. Another useful technique to +reduce iterations/wake-ups is to use C watchers and make sure +they fire on, say, one-second boundaries only. + +Example: we only need 0.1s timeout granularity, and we wish not to poll +more often than 100 times per second: + + ev_set_timeout_collect_interval (EV_DEFAULT_UC_ 0.1); + ev_set_io_collect_interval (EV_DEFAULT_UC_ 0.01); + +=item ev_invoke_pending (loop) + +This call will simply invoke all pending watchers while resetting their +pending state. Normally, C does this automatically when required, +but when overriding the invoke callback this call comes handy. This +function can be invoked from a watcher - this can be useful for example +when you want to do some lengthy calculation and want to pass further +event handling to another thread (you still have to make sure only one +thread executes within C or C of course). + +=item int ev_pending_count (loop) + +Returns the number of pending watchers - zero indicates that no watchers +are pending. + +=item ev_set_invoke_pending_cb (loop, void (*invoke_pending_cb)(EV_P)) + +This overrides the invoke pending functionality of the loop: Instead of +invoking all pending watchers when there are any, C will call +this callback instead. This is useful, for example, when you want to +invoke the actual watchers inside another context (another thread etc.). + +If you want to reset the callback, use C as new +callback. + +=item ev_set_loop_release_cb (loop, void (*release)(EV_P) throw (), void (*acquire)(EV_P) throw ()) + +Sometimes you want to share the same loop between multiple threads. This +can be done relatively simply by putting mutex_lock/unlock calls around +each call to a libev function. + +However, C can run an indefinite time, so it is not feasible +to wait for it to return. One way around this is to wake up the event +loop via C and C, another way is to set these +I and I callbacks on the loop. + +When set, then C will be called just before the thread is +suspended waiting for new events, and C is called just +afterwards. + +Ideally, C will just call your mutex_unlock function, and +C will just call the mutex_lock function again. + +While event loop modifications are allowed between invocations of +C and C (that's their only purpose after all), no +modifications done will affect the event loop, i.e. adding watchers will +have no effect on the set of file descriptors being watched, or the time +waited. Use an C watcher to wake up C when you want it +to take note of any changes you made. + +In theory, threads executing C will be async-cancel safe between +invocations of C and C. + +See also the locking example in the C section later in this +document. + +=item ev_set_userdata (loop, void *data) + +=item void *ev_userdata (loop) + +Set and retrieve a single C associated with a loop. When +C has never been called, then C returns +C<0>. + +These two functions can be used to associate arbitrary data with a loop, +and are intended solely for the C, C and +C callbacks described above, but of course can be (ab-)used for +any other purpose as well. + +=item ev_verify (loop) + +This function only does something when C support has been +compiled in, which is the default for non-minimal builds. It tries to go +through all internal structures and checks them for validity. If anything +is found to be inconsistent, it will print an error message to standard +error and call C. + +This can be used to catch bugs inside libev itself: under normal +circumstances, this function will never abort as of course libev keeps its +data structures consistent. + +=back + + +=head1 ANATOMY OF A WATCHER + +In the following description, uppercase C in names stands for the +watcher type, e.g. C can mean C for timer +watchers and C for I/O watchers. + +A watcher is an opaque structure that you allocate and register to record +your interest in some event. To make a concrete example, imagine you want +to wait for STDIN to become readable, you would create an C watcher +for that: + + static void my_cb (struct ev_loop *loop, ev_io *w, int revents) + { + ev_io_stop (w); + ev_break (loop, EVBREAK_ALL); + } + + struct ev_loop *loop = ev_default_loop (0); + + ev_io stdin_watcher; + + ev_init (&stdin_watcher, my_cb); + ev_io_set (&stdin_watcher, STDIN_FILENO, EV_READ); + ev_io_start (loop, &stdin_watcher); + + ev_run (loop, 0); + +As you can see, you are responsible for allocating the memory for your +watcher structures (and it is I a bad idea to do this on the +stack). + +Each watcher has an associated watcher structure (called C +or simply C, as typedefs are provided for all watcher structs). + +Each watcher structure must be initialised by a call to C, which expects a callback to be provided. This callback is +invoked each time the event occurs (or, in the case of I/O watchers, each +time the event loop detects that the file descriptor given is readable +and/or writable). + +Each watcher type further has its own C<< ev_TYPE_set (watcher *, ...) >> +macro to configure it, with arguments specific to the watcher type. There +is also a macro to combine initialisation and setting in one call: C<< +ev_TYPE_init (watcher *, callback, ...) >>. + +To make the watcher actually watch out for events, you have to start it +with a watcher-specific start function (C<< ev_TYPE_start (loop, watcher +*) >>), and you can stop watching for events at any time by calling the +corresponding stop function (C<< ev_TYPE_stop (loop, watcher *) >>. + +As long as your watcher is active (has been started but not stopped) you +must not touch the values stored in it except when explicitly documented +otherwise. Most specifically you must never reinitialise it or call its +C macro. + +Each and every callback receives the event loop pointer as first, the +registered watcher structure as second, and a bitset of received events as +third argument. + +The received events usually include a single bit per event type received +(you can receive multiple events at the same time). The possible bit masks +are: + +=over 4 + +=item C + +=item C + +The file descriptor in the C watcher has become readable and/or +writable. + +=item C + +The C watcher has timed out. + +=item C + +The C watcher has timed out. + +=item C + +The signal specified in the C watcher has been received by a thread. + +=item C + +The pid specified in the C watcher has received a status change. + +=item C + +The path specified in the C watcher changed its attributes somehow. + +=item C + +The C watcher has determined that you have nothing better to do. + +=item C + +=item C + +All C watchers are invoked just I C starts to +gather new events, and all C watchers are queued (not invoked) +just after C has gathered them, but before it queues any callbacks +for any received events. That means C watchers are the last +watchers invoked before the event loop sleeps or polls for new events, and +C watchers will be invoked before any other watchers of the same +or lower priority within an event loop iteration. + +Callbacks of both watcher types can start and stop as many watchers as +they want, and all of them will be taken into account (for example, a +C watcher might start an idle watcher to keep C from +blocking). + +=item C + +The embedded event loop specified in the C watcher needs attention. + +=item C + +The event loop has been resumed in the child process after fork (see +C). + +=item C + +The event loop is about to be destroyed (see C). + +=item C + +The given async watcher has been asynchronously notified (see C). + +=item C + +Not ever sent (or otherwise used) by libev itself, but can be freely used +by libev users to signal watchers (e.g. via C). + +=item C + +An unspecified error has occurred, the watcher has been stopped. This might +happen because the watcher could not be properly started because libev +ran out of memory, a file descriptor was found to be closed or any other +problem. Libev considers these application bugs. + +You best act on it by reporting the problem and somehow coping with the +watcher being stopped. Note that well-written programs should not receive +an error ever, so when your watcher receives it, this usually indicates a +bug in your program. + +Libev will usually signal a few "dummy" events together with an error, for +example it might indicate that a fd is readable or writable, and if your +callbacks is well-written it can just attempt the operation and cope with +the error from read() or write(). This will not work in multi-threaded +programs, though, as the fd could already be closed and reused for another +thing, so beware. + +=back + +=head2 GENERIC WATCHER FUNCTIONS + +=over 4 + +=item C (ev_TYPE *watcher, callback) + +This macro initialises the generic portion of a watcher. The contents +of the watcher object can be arbitrary (so C will do). Only +the generic parts of the watcher are initialised, you I to call +the type-specific C macro afterwards to initialise the +type-specific parts. For each type there is also a C macro +which rolls both calls into one. + +You can reinitialise a watcher at any time as long as it has been stopped +(or never started) and there are no pending events outstanding. + +The callback is always of type C. + +Example: Initialise an C watcher in two steps. + + ev_io w; + ev_init (&w, my_cb); + ev_io_set (&w, STDIN_FILENO, EV_READ); + +=item C (ev_TYPE *watcher, [args]) + +This macro initialises the type-specific parts of a watcher. You need to +call C at least once before you call this macro, but you can +call C any number of times. You must not, however, call this +macro on a watcher that is active (it can be pending, however, which is a +difference to the C macro). + +Although some watcher types do not have type-specific arguments +(e.g. C) you still need to call its C macro. + +See C, above, for an example. + +=item C (ev_TYPE *watcher, callback, [args]) + +This convenience macro rolls both C and C macro +calls into a single call. This is the most convenient method to initialise +a watcher. The same limitations apply, of course. + +Example: Initialise and set an C watcher in one step. + + ev_io_init (&w, my_cb, STDIN_FILENO, EV_READ); + +=item C (loop, ev_TYPE *watcher) + +Starts (activates) the given watcher. Only active watchers will receive +events. If the watcher is already active nothing will happen. + +Example: Start the C watcher that is being abused as example in this +whole section. + + ev_io_start (EV_DEFAULT_UC, &w); + +=item C (loop, ev_TYPE *watcher) + +Stops the given watcher if active, and clears the pending status (whether +the watcher was active or not). + +It is possible that stopped watchers are pending - for example, +non-repeating timers are being stopped when they become pending - but +calling C ensures that the watcher is neither active nor +pending. If you want to free or reuse the memory used by the watcher it is +therefore a good idea to always call its C function. + +=item bool ev_is_active (ev_TYPE *watcher) + +Returns a true value iff the watcher is active (i.e. it has been started +and not yet been stopped). As long as a watcher is active you must not modify +it. + +=item bool ev_is_pending (ev_TYPE *watcher) + +Returns a true value iff the watcher is pending, (i.e. it has outstanding +events but its callback has not yet been invoked). As long as a watcher +is pending (but not active) you must not call an init function on it (but +C is safe), you must not change its priority, and you must +make sure the watcher is available to libev (e.g. you cannot C +it). + +=item callback ev_cb (ev_TYPE *watcher) + +Returns the callback currently set on the watcher. + +=item ev_set_cb (ev_TYPE *watcher, callback) + +Change the callback. You can change the callback at virtually any time +(modulo threads). + +=item ev_set_priority (ev_TYPE *watcher, int priority) + +=item int ev_priority (ev_TYPE *watcher) + +Set and query the priority of the watcher. The priority is a small +integer between C (default: C<2>) and C +(default: C<-2>). Pending watchers with higher priority will be invoked +before watchers with lower priority, but priority will not keep watchers +from being executed (except for C watchers). + +If you need to suppress invocation when higher priority events are pending +you need to look at C watchers, which provide this functionality. + +You I change the priority of a watcher as long as it is active or +pending. + +Setting a priority outside the range of C to C is +fine, as long as you do not mind that the priority value you query might +or might not have been clamped to the valid range. + +The default priority used by watchers when no priority has been set is +always C<0>, which is supposed to not be too high and not be too low :). + +See L, below, for a more thorough treatment of +priorities. + +=item ev_invoke (loop, ev_TYPE *watcher, int revents) + +Invoke the C with the given C and C. Neither +C nor C need to be valid as long as the watcher callback +can deal with that fact, as both are simply passed through to the +callback. + +=item int ev_clear_pending (loop, ev_TYPE *watcher) + +If the watcher is pending, this function clears its pending status and +returns its C bitset (as if its callback was invoked). If the +watcher isn't pending it does nothing and returns C<0>. + +Sometimes it can be useful to "poll" a watcher instead of waiting for its +callback to be invoked, which can be accomplished with this function. + +=item ev_feed_event (loop, ev_TYPE *watcher, int revents) + +Feeds the given event set into the event loop, as if the specified event +had happened for the specified watcher (which must be a pointer to an +initialised but not necessarily started event watcher). Obviously you must +not free the watcher as long as it has pending events. + +Stopping the watcher, letting libev invoke it, or calling +C will clear the pending event, even if the watcher was +not started in the first place. + +See also C and C for related +functions that do not need a watcher. + +=back + +See also the L and L idioms. + +=head2 WATCHER STATES + +There are various watcher states mentioned throughout this manual - +active, pending and so on. In this section these states and the rules to +transition between them will be described in more detail - and while these +rules might look complicated, they usually do "the right thing". + +=over 4 + +=item initialised + +Before a watcher can be registered with the event loop it has to be +initialised. This can be done with a call to C, or calls to +C followed by the watcher-specific C function. + +In this state it is simply some block of memory that is suitable for +use in an event loop. It can be moved around, freed, reused etc. at +will - as long as you either keep the memory contents intact, or call +C again. + +=item started/running/active + +Once a watcher has been started with a call to C it becomes +property of the event loop, and is actively waiting for events. While in +this state it cannot be accessed (except in a few documented ways), moved, +freed or anything else - the only legal thing is to keep a pointer to it, +and call libev functions on it that are documented to work on active watchers. + +=item pending + +If a watcher is active and libev determines that an event it is interested +in has occurred (such as a timer expiring), it will become pending. It will +stay in this pending state until either it is stopped or its callback is +about to be invoked, so it is not normally pending inside the watcher +callback. + +The watcher might or might not be active while it is pending (for example, +an expired non-repeating timer can be pending but no longer active). If it +is stopped, it can be freely accessed (e.g. by calling C), +but it is still property of the event loop at this time, so cannot be +moved, freed or reused. And if it is active the rules described in the +previous item still apply. + +It is also possible to feed an event on a watcher that is not active (e.g. +via C), in which case it becomes pending without being +active. + +=item stopped + +A watcher can be stopped implicitly by libev (in which case it might still +be pending), or explicitly by calling its C function. The +latter will clear any pending state the watcher might be in, regardless +of whether it was active or not, so stopping a watcher explicitly before +freeing it is often a good idea. + +While stopped (and not pending) the watcher is essentially in the +initialised state, that is, it can be reused, moved, modified in any way +you wish (but when you trash the memory block, you need to C +it again). + +=back + +=head2 WATCHER PRIORITY MODELS + +Many event loops support I, which are usually small +integers that influence the ordering of event callback invocation +between watchers in some way, all else being equal. + +In libev, watcher priorities can be set using C. See its +description for the more technical details such as the actual priority +range. + +There are two common ways how these these priorities are being interpreted +by event loops: + +In the more common lock-out model, higher priorities "lock out" invocation +of lower priority watchers, which means as long as higher priority +watchers receive events, lower priority watchers are not being invoked. + +The less common only-for-ordering model uses priorities solely to order +callback invocation within a single event loop iteration: Higher priority +watchers are invoked before lower priority ones, but they all get invoked +before polling for new events. + +Libev uses the second (only-for-ordering) model for all its watchers +except for idle watchers (which use the lock-out model). + +The rationale behind this is that implementing the lock-out model for +watchers is not well supported by most kernel interfaces, and most event +libraries will just poll for the same events again and again as long as +their callbacks have not been executed, which is very inefficient in the +common case of one high-priority watcher locking out a mass of lower +priority ones. + +Static (ordering) priorities are most useful when you have two or more +watchers handling the same resource: a typical usage example is having an +C watcher to receive data, and an associated C to handle +timeouts. Under load, data might be received while the program handles +other jobs, but since timers normally get invoked first, the timeout +handler will be executed before checking for data. In that case, giving +the timer a lower priority than the I/O watcher ensures that I/O will be +handled first even under adverse conditions (which is usually, but not +always, what you want). + +Since idle watchers use the "lock-out" model, meaning that idle watchers +will only be executed when no same or higher priority watchers have +received events, they can be used to implement the "lock-out" model when +required. + +For example, to emulate how many other event libraries handle priorities, +you can associate an C watcher to each such watcher, and in +the normal watcher callback, you just start the idle watcher. The real +processing is done in the idle watcher callback. This causes libev to +continuously poll and process kernel event data for the watcher, but when +the lock-out case is known to be rare (which in turn is rare :), this is +workable. + +Usually, however, the lock-out model implemented that way will perform +miserably under the type of load it was designed to handle. In that case, +it might be preferable to stop the real watcher before starting the +idle watcher, so the kernel will not have to process the event in case +the actual processing will be delayed for considerable time. + +Here is an example of an I/O watcher that should run at a strictly lower +priority than the default, and which should only process data when no +other events are pending: + + ev_idle idle; // actual processing watcher + ev_io io; // actual event watcher + + static void + io_cb (EV_P_ ev_io *w, int revents) + { + // stop the I/O watcher, we received the event, but + // are not yet ready to handle it. + ev_io_stop (EV_A_ w); + + // start the idle watcher to handle the actual event. + // it will not be executed as long as other watchers + // with the default priority are receiving events. + ev_idle_start (EV_A_ &idle); + } + + static void + idle_cb (EV_P_ ev_idle *w, int revents) + { + // actual processing + read (STDIN_FILENO, ...); + + // have to start the I/O watcher again, as + // we have handled the event + ev_io_start (EV_P_ &io); + } + + // initialisation + ev_idle_init (&idle, idle_cb); + ev_io_init (&io, io_cb, STDIN_FILENO, EV_READ); + ev_io_start (EV_DEFAULT_ &io); + +In the "real" world, it might also be beneficial to start a timer, so that +low-priority connections can not be locked out forever under load. This +enables your program to keep a lower latency for important connections +during short periods of high load, while not completely locking out less +important ones. + + +=head1 WATCHER TYPES + +This section describes each watcher in detail, but will not repeat +information given in the last section. Any initialisation/set macros, +functions and members specific to the watcher type are explained. + +Most members are additionally marked with either I<[read-only]>, meaning +that, while the watcher is active, you can look at the member and expect +some sensible content, but you must not modify it (you can modify it while +the watcher is stopped to your hearts content), or I<[read-write]>, which +means you can expect it to have some sensible content while the watcher is +active, but you can also modify it (within the same thread as the event +loop, i.e. without creating data races). Modifying it may not do something +sensible or take immediate effect (or do anything at all), but libev will +not crash or malfunction in any way. + +In any case, the documentation for each member will explain what the +effects are, and if there are any additional access restrictions. + +=head2 C - is this file descriptor readable or writable? + +I/O watchers check whether a file descriptor is readable or writable +in each iteration of the event loop, or, more precisely, when reading +would not block the process and writing would at least be able to write +some data. This behaviour is called level-triggering because you keep +receiving events as long as the condition persists. Remember you can stop +the watcher if you don't want to act on the event and neither want to +receive future events. + +In general you can register as many read and/or write event watchers per +fd as you want (as long as you don't confuse yourself). Setting all file +descriptors to non-blocking mode is also usually a good idea (but not +required if you know what you are doing). + +Another thing you have to watch out for is that it is quite easy to +receive "spurious" readiness notifications, that is, your callback might +be called with C but a subsequent C(2) will actually block +because there is no data. It is very easy to get into this situation even +with a relatively standard program structure. Thus it is best to always +use non-blocking I/O: An extra C(2) returning C is far +preferable to a program hanging until some data arrives. + +If you cannot run the fd in non-blocking mode (for example you should +not play around with an Xlib connection), then you have to separately +re-test whether a file descriptor is really ready with a known-to-be good +interface such as poll (fortunately in the case of Xlib, it already does +this on its own, so its quite safe to use). Some people additionally +use C and an interval timer, just to be sure you won't block +indefinitely. + +But really, best use non-blocking mode. + +=head3 The special problem of disappearing file descriptors + +Some backends (e.g. kqueue, epoll, linuxaio) need to be told about closing +a file descriptor (either due to calling C explicitly or any other +means, such as C). The reason is that you register interest in some +file descriptor, but when it goes away, the operating system will silently +drop this interest. If another file descriptor with the same number then +is registered with libev, there is no efficient way to see that this is, +in fact, a different file descriptor. + +To avoid having to explicitly tell libev about such cases, libev follows +the following policy: Each time C is being called, libev +will assume that this is potentially a new file descriptor, otherwise +it is assumed that the file descriptor stays the same. That means that +you I to call C (or C) when you change the +descriptor even if the file descriptor number itself did not change. + +This is how one would do it normally anyway, the important point is that +the libev application should not optimise around libev but should leave +optimisations to libev. + +=head3 The special problem of dup'ed file descriptors + +Some backends (e.g. epoll), cannot register events for file descriptors, +but only events for the underlying file descriptions. That means when you +have C'ed file descriptors or weirder constellations, and register +events for them, only one file descriptor might actually receive events. + +There is no workaround possible except not registering events +for potentially C'ed file descriptors, or to resort to +C or C. + +=head3 The special problem of files + +Many people try to use C. + +=item EV_USE_EVENTFD + +If defined to be C<1>, then libev will assume that C is +available and will probe for kernel support at runtime. This will improve +C and C performance and reduce resource consumption. +If undefined, it will be enabled if the headers indicate GNU/Linux + Glibc +2.7 or newer, otherwise disabled. + +=item EV_USE_SIGNALFD + +If defined to be C<1>, then libev will assume that C is +available and will probe for kernel support at runtime. This enables +the use of EVFLAG_SIGNALFD for faster and simpler signal handling. If +undefined, it will be enabled if the headers indicate GNU/Linux + Glibc +2.7 or newer, otherwise disabled. + +=item EV_USE_TIMERFD + +If defined to be C<1>, then libev will assume that C is +available and will probe for kernel support at runtime. This allows +libev to detect time jumps accurately. If undefined, it will be enabled +if the headers indicate GNU/Linux + Glibc 2.8 or newer and define +C, otherwise disabled. + +=item EV_USE_EVENTFD + +If defined to be C<1>, then libev will assume that C is +available and will probe for kernel support at runtime. This will improve +C and C performance and reduce resource consumption. +If undefined, it will be enabled if the headers indicate GNU/Linux + Glibc +2.7 or newer, otherwise disabled. + +=item EV_USE_SELECT + +If undefined or defined to be C<1>, libev will compile in support for the +C is buggy + +All that's left is C actively limits the number of file +descriptors you can pass in to 1024 - your program suddenly crashes when +you use more. + +There is an undocumented "workaround" for this - defining +C<_DARWIN_UNLIMITED_SELECT>, which libev tries to use, so select I +work on OS/X. + +=head2 SOLARIS PROBLEMS AND WORKAROUNDS + +=head3 C reentrancy + +The default compile environment on Solaris is unfortunately so +thread-unsafe that you can't even use components/libraries compiled +without C<-D_REENTRANT> in a threaded program, which, of course, isn't +defined by default. A valid, if stupid, implementation choice. + +If you want to use libev in threaded environments you have to make sure +it's compiled with C<_REENTRANT> defined. + +=head3 Event port backend + +The scalable event interface for Solaris is called "event +ports". Unfortunately, this mechanism is very buggy in all major +releases. If you run into high CPU usage, your program freezes or you get +a large number of spurious wakeups, make sure you have all the relevant +and latest kernel patches applied. No, I don't know which ones, but there +are multiple ones to apply, and afterwards, event ports actually work +great. + +If you can't get it to work, you can try running the program by setting +the environment variable C to only allow C and +C works fine +with large bitsets on AIX, and AIX is dead anyway. + +=head2 WIN32 PLATFORM LIMITATIONS AND WORKAROUNDS + +=head3 General issues + +Win32 doesn't support any of the standards (e.g. POSIX) that libev +requires, and its I/O model is fundamentally incompatible with the POSIX +model. Libev still offers limited functionality on this platform in +the form of the C backend, and only supports socket +descriptors. This only applies when using Win32 natively, not when using +e.g. cygwin. Actually, it only applies to the microsofts own compilers, +as every compiler comes with a slightly differently broken/incompatible +environment. + +Lifting these limitations would basically require the full +re-implementation of the I/O system. If you are into this kind of thing, +then note that glib does exactly that for you in a very portable way (note +also that glib is the slowest event library known to man). + +There is no supported compilation method available on windows except +embedding it into other applications. + +Sensible signal handling is officially unsupported by Microsoft - libev +tries its best, but under most conditions, signals will simply not work. + +Not a libev limitation but worth mentioning: windows apparently doesn't +accept large writes: instead of resulting in a partial write, windows will +either accept everything or return C if the buffer is too large, +so make sure you only write small amounts into your sockets (less than a +megabyte seems safe, but this apparently depends on the amount of memory +available). + +Due to the many, low, and arbitrary limits on the win32 platform and +the abysmal performance of winsockets, using a large number of sockets +is not recommended (and not reasonable). If your program needs to use +more than a hundred or so sockets, then likely it needs to use a totally +different implementation for windows, as libev offers the POSIX readiness +notification model, which cannot be implemented efficiently on windows +(due to Microsoft monopoly games). + +A typical way to use libev under windows is to embed it (see the embedding +section for details) and use the following F header file instead +of F: + + #define EV_STANDALONE /* keeps ev from requiring config.h */ + #define EV_SELECT_IS_WINSOCKET 1 /* configure libev for windows select */ + + #include "ev.h" + +And compile the following F file into your project (make sure +you do I compile the F or any other embedded source files!): + + #include "evwrap.h" + #include "ev.c" + +=head3 The winsocket C function doesn't follow POSIX in that it +requires socket I and not socket I (it is +also extremely buggy). This makes select very inefficient, and also +requires a mapping from file descriptors to socket handles (the Microsoft +C runtime provides the function C<_open_osfhandle> for this). See the +discussion of the C, C and +C preprocessor symbols for more info. + +The configuration for a "naked" win32 using the Microsoft runtime +libraries and raw winsocket select is: + + #define EV_USE_SELECT 1 + #define EV_SELECT_IS_WINSOCKET 1 /* forces EV_SELECT_USE_FD_SET, too */ + +Note that winsockets handling of fd sets is O(n), so you can easily get a +complexity in the O(n²) range when using win32. + +=head3 Limited number of file descriptors + +Windows has numerous arbitrary (and low) limits on things. + +Early versions of winsocket's select only supported waiting for a maximum +of C<64> handles (probably owning to the fact that all windows kernels +can only wait for C<64> things at the same time internally; Microsoft +recommends spawning a chain of threads and wait for 63 handles and the +previous thread in each. Sounds great!). + +Newer versions support more handles, but you need to define C +to some high number (e.g. C<2048>) before compiling the winsocket select +call (which might be in libev or elsewhere, for example, perl and many +other interpreters do their own select emulation on windows). + +Another limit is the number of file descriptors in the Microsoft runtime +libraries, which by default is C<64> (there must be a hidden I<64> +fetish or something like this inside Microsoft). You can increase this +by calling C<_setmaxstdio>, which can increase this limit to C<2048> +(another arbitrary limit), but is broken in many versions of the Microsoft +runtime libraries. This might get you to about C<512> or C<2048> sockets +(depending on windows version and/or the phase of the moon). To get more, +you need to wrap all I/O functions and provide your own fd management, but +the cost of calling select (O(n²)) will likely make this unworkable. + +=head2 PORTABILITY REQUIREMENTS + +In addition to a working ISO-C implementation and of course the +backend-specific APIs, libev relies on a few additional extensions: + +=over 4 + +=item C must have compatible +calling conventions regardless of C. + +Libev assumes not only that all watcher pointers have the same internal +structure (guaranteed by POSIX but not by ISO C for example), but it also +assumes that the same (machine) code can be used to call any watcher +callback: The watcher callbacks have different type signatures, but libev +calls them using an C internally. + +=item null pointers and integer zero are represented by 0 bytes + +Libev uses C to initialise structs and arrays to C<0> bytes, and +relies on this setting pointers and integers to null. + +=item pointer accesses must be thread-atomic + +Accessing a pointer value must be atomic, it must both be readable and +writable in one piece - this is the case on all current architectures. + +=item C must be thread-atomic as well + +The type C (or whatever is defined as +C) must be atomic with respect to accesses from different +threads. This is not part of the specification for C, but is +believed to be sufficiently portable. + +=item C must work in a threaded environment + +Libev uses C to temporarily block signals. This is not +allowed in a threaded program (C has to be used). Typical +pthread implementations will either allow C in the "main +thread" or will block signals process-wide, both behaviours would +be compatible with libev. Interaction between C and +C could complicate things, however. + +The most portable way to handle signals is to block signals in all threads +except the initial one, and run the signal handling loop in the initial +thread as well. + +=item C must be large enough for common memory allocation sizes + +To improve portability and simplify its API, libev uses C internally +instead of C when allocating its data structures. On non-POSIX +systems (Microsoft...) this might be unexpectedly low, but is still at +least 31 bits everywhere, which is enough for hundreds of millions of +watchers. + +=item C must hold a time value in seconds with enough accuracy + +The type C is used to represent timestamps. It is required to +have at least 51 bits of mantissa (and 9 bits of exponent), which is +good enough for at least into the year 4000 with millisecond accuracy +(the design goal for libev). This requirement is overfulfilled by +implementations using IEEE 754, which is basically all existing ones. + +With IEEE 754 doubles, you get microsecond accuracy until at least the +year 2255 (and millisecond accuracy till the year 287396 - by then, libev +is either obsolete or somebody patched it to use C or +something like that, just kidding). + +=back + +If you know of other additional requirements drop me a note. + + +=head1 ALGORITHMIC COMPLEXITIES + +In this section the complexities of (many of) the algorithms used inside +libev will be documented. For complexity discussions about backends see +the documentation for C. + +All of the following are about amortised time: If an array needs to be +extended, libev needs to realloc and move the whole array, but this +happens asymptotically rarer with higher number of elements, so O(1) might +mean that libev does a lengthy realloc operation in rare cases, but on +average it is much faster and asymptotically approaches constant time. + +=over 4 + +=item Starting and stopping timer/periodic watchers: O(log skipped_other_timers) + +This means that, when you have a watcher that triggers in one hour and +there are 100 watchers that would trigger before that, then inserting will +have to skip roughly seven (C) of these watchers. + +=item Changing timer/periodic watchers (by autorepeat or calling again): O(log skipped_other_timers) + +That means that changing a timer costs less than removing/adding them, +as only the relative motion in the event queue has to be paid for. + +=item Starting io/check/prepare/idle/signal/child/fork/async watchers: O(1) + +These just add the watcher into an array or at the head of a list. + +=item Stopping check/prepare/idle/fork/async watchers: O(1) + +=item Stopping an io/signal/child watcher: O(number_of_watchers_for_this_(fd/signal/pid % EV_PID_HASHSIZE)) + +These watchers are stored in lists, so they need to be walked to find the +correct watcher to remove. The lists are usually short (you don't usually +have many watchers waiting for the same fd or signal: one is typical, two +is rare). + +=item Finding the next timer in each loop iteration: O(1) + +By virtue of using a binary or 4-heap, the next timer is always found at a +fixed position in the storage array. + +=item Each change on a file descriptor per loop iteration: O(number_of_watchers_for_this_fd) + +A change means an I/O watcher gets started or stopped, which requires +libev to recalculate its status (and possibly tell the kernel, depending +on backend and whether C was used). + +=item Activating one watcher (putting it into the pending state): O(1) + +=item Priority handling: O(number_of_priorities) + +Priorities are implemented by allocating some space for each +priority. When doing priority-based operations, libev usually has to +linearly search all the priorities, but starting/stopping and activating +watchers becomes O(1) with respect to priority handling. + +=item Sending an ev_async: O(1) + +=item Processing ev_async_send: O(number_of_async_watchers) + +=item Processing signals: O(max_signal_number) + +Sending involves a system call I there were no other C +calls in the current loop iteration and the loop is currently +blocked. Checking for async and signal events involves iterating over all +running async watchers or all signal numbers. + +=back + + +=head1 PORTING FROM LIBEV 3.X TO 4.X + +The major version 4 introduced some incompatible changes to the API. + +At the moment, the C header file provides compatibility definitions +for all changes, so most programs should still compile. The compatibility +layer might be removed in later versions of libev, so better update to the +new API early than late. + +=over 4 + +=item C backwards compatibility mechanism + +The backward compatibility mechanism can be controlled by +C.

+ * c) well, linux as usual: the documentation lies to you: io_submit + * sometimes returns EINVAL because the kernel doesn't feel like + * handling your poll mask - ttys can be polled for POLLOUT, + * POLLOUT|POLLIN, but polling for POLLIN fails. just great, + * so we have to fall back to something else (hello, epoll), + * but at least the fallback can be slow, because these are + * exceptional cases, right? + * d) hmm, you have to tell the kernel the maximum number of watchers + * you want to queue when initialising the aio context. but of + * course the real limit is magically calculated in the kernel, and + * is often higher then we asked for. so we just have to destroy + * the aio context and re-create it a bit larger if we hit the limit. + * (starts to remind you of epoll?

It parses both requests and +responses. The parser is designed to be used in performance HTTP +applications. It does not make any syscalls nor allocations, it does not +buffer data, it can be interrupted at anytime. Depending on your +architecture, it only requires about 40 bytes of data per message +stream (in a web server that is per connection). + +Features: + + * No dependencies + * Handles persistent streams (keep-alive). + * Decodes chunked encoding. + * Upgrade support + * Defends against buffer overflow attacks. + +The parser extracts the following information from HTTP messages: + + * Header fields and values + * Content-Length + * Request method + * Response status code + * Transfer-Encoding + * HTTP version + * Request URL + * Message body + + +Usage +----- + +One `http_parser` object is used per TCP connection. Initialize the struct +using `http_parser_init()` and set the callbacks. That might look something +like this for a request parser: +```c +http_parser_settings settings; +settings.on_url = my_url_callback; +settings.on_header_field = my_header_field_callback; +/* ... */ + +http_parser *parser = malloc(sizeof(http_parser)); +http_parser_init(parser, HTTP_REQUEST); +parser->data = my_socket; +``` + +When data is received on the socket execute the parser and check for errors. + +```c +size_t len = 80*1024, nparsed; +char buf[len]; +ssize_t recved; + +recved = recv(fd, buf, len, 0); + +if (recved < 0) { + /* Handle error. */ +} + +/* Start up / continue the parser. + * Note we pass recved==0 to signal that EOF has been received. + */ +nparsed = http_parser_execute(parser, &settings, buf, recved); + +if (parser->upgrade) { + /* handle new protocol */ +} else if (nparsed != recved) { + /* Handle error. Usually just close the connection. */ +} +``` + +`http_parser` needs to know where the end of the stream is. For example, sometimes +servers send responses without Content-Length and expect the client to +consume input (for the body) until EOF. To tell `http_parser` about EOF, give +`0` as the fourth parameter to `http_parser_execute()`. Callbacks and errors +can still be encountered during an EOF, so one must still be prepared +to receive them. + +Scalar valued message information such as `status_code`, `method`, and the +HTTP version are stored in the parser structure. This data is only +temporally stored in `http_parser` and gets reset on each new message. If +this information is needed later, copy it out of the structure during the +`headers_complete` callback. + +The parser decodes the transfer-encoding for both requests and responses +transparently. That is, a chunked encoding is decoded before being sent to +the on_body callback. + + +The Special Problem of Upgrade +------------------------------ + +`http_parser` supports upgrading the connection to a different protocol. An +increasingly common example of this is the WebSocket protocol which sends +a request like + + GET /demo HTTP/1.1 + Upgrade: WebSocket + Connection: Upgrade + Host: example.com + Origin: http://example.com + WebSocket-Protocol: sample + +followed by non-HTTP data. + +(See [RFC6455](https://tools.ietf.org/html/rfc6455) for more information the +WebSocket protocol.) + +To support this, the parser will treat this as a normal HTTP message without a +body, issuing both on_headers_complete and on_message_complete callbacks. However +http_parser_execute() will stop parsing at the end of the headers and return. + +The user is expected to check if `parser->upgrade` has been set to 1 after +`http_parser_execute()` returns. Non-HTTP data begins at the buffer supplied +offset by the return value of `http_parser_execute()`. + + +Callbacks +--------- + +During the `http_parser_execute()` call, the callbacks set in +`http_parser_settings` will be executed. The parser maintains state and +never looks behind, so buffering the data is not necessary. If you need to +save certain data for later usage, you can do that from the callbacks. + +There are two types of callbacks: + +* notification `typedef int (*http_cb) (http_parser*);` + Callbacks: on_message_begin, on_headers_complete, on_message_complete. +* data `typedef int (*http_data_cb) (http_parser*, const char *at, size_t length);` + Callbacks: (requests only) on_url, + (common) on_header_field, on_header_value, on_body; + +Callbacks must return 0 on success. Returning a non-zero value indicates +error to the parser, making it exit immediately. + +For cases where it is necessary to pass local information to/from a callback, +the `http_parser` object's `data` field can be used. +An example of such a case is when using threads to handle a socket connection, +parse a request, and then give a response over that socket. By instantiation +of a thread-local struct containing relevant data (e.g. accepted socket, +allocated memory for callbacks to write into, etc), a parser's callbacks are +able to communicate data between the scope of the thread and the scope of the +callback in a threadsafe manner. This allows `http_parser` to be used in +multi-threaded contexts. + +Example: +```c + typedef struct { + socket_t sock; + void* buffer; + int buf_len; + } custom_data_t; + + +int my_url_callback(http_parser* parser, const char *at, size_t length) { + /* access to thread local custom_data_t struct. + Use this access save parsed data for later use into thread local + buffer, or communicate over socket + */ + parser->data; + ... + return 0; +} + +... + +void http_parser_thread(socket_t sock) { + int nparsed = 0; + /* allocate memory for user data */ + custom_data_t *my_data = malloc(sizeof(custom_data_t)); + + /* some information for use by callbacks. + * achieves thread -> callback information flow */ + my_data->sock = sock; + + /* instantiate a thread-local parser */ + http_parser *parser = malloc(sizeof(http_parser)); + http_parser_init(parser, HTTP_REQUEST); /* initialise parser */ + /* this custom data reference is accessible through the reference to the + parser supplied to callback functions */ + parser->data = my_data; + + http_parser_settings settings; /* set up callbacks */ + settings.on_url = my_url_callback; + + /* execute parser */ + nparsed = http_parser_execute(parser, &settings, buf, recved); + + ... + /* parsed information copied from callback. + can now perform action on data copied into thread-local memory from callbacks. + achieves callback -> thread information flow */ + my_data->buffer; + ... +} + +``` + +In case you parse HTTP message in chunks (i.e. `read()` request line +from socket, parse, read half headers, parse, etc) your data callbacks +may be called more than once. `http_parser` guarantees that data pointer is only +valid for the lifetime of callback. You can also `read()` into a heap allocated +buffer to avoid copying memory around if this fits your application. + +Reading headers may be a tricky task if you read/parse headers partially. +Basically, you need to remember whether last header callback was field or value +and apply the following logic: + + (on_header_field and on_header_value shortened to on_h_*) + ------------------------ ------------ -------------------------------------------- + | State (prev. callback) | Callback | Description/action | + ------------------------ ------------ -------------------------------------------- + | nothing (first call) | on_h_field | Allocate new buffer and copy callback data | + | | | into it | + ------------------------ ------------ -------------------------------------------- + | value | on_h_field | New header started. | + | | | Copy current name,value buffers to headers | + | | | list and allocate new buffer for new name | + ------------------------ ------------ -------------------------------------------- + | field | on_h_field | Previous name continues.
