If we don't mess up, this will more or less guarantee binaries linked against old versions of libevent continue working when we make changes to libevent that do not break backward compatibility. + o Fix evhttp.h compilation when TAILQ_ENTRY is not defined. + o Small code cleanups in epoll_dispatch(). + o Increase the maximum number of addresses read from a packet in evdns to 32. + o Remove support for the rtsig method: it hasn't compiled for a while, and nobody seems to miss it very much. Let us know if there's a good reason to put it back in. + o Rename the "class" field in evdns_server_request to dns_question_class, so that it won't break compilation under C++. Use a macro so that old code won't break. Mark the macro as deprecated. + o Fix DNS unit tests so that having a DNS server with broken IPv6 support is no longer cause for aborting the unit tests. + o Make event_base_free() succeed even if there are pending non-internal events on a base. This may still leak memory and fds, but at least it no longer crashes. + o Post-process the config.h file into a new, installed event-config.h file that we can install, and whose macros will be safe to include in header files. + o Remove the long-deprecated acconfig.h file. + o Do not require #include <sys/types.h> before #include <event.h>. + o Add new evutil_timer* functions to wrap (or replace) the regular timeval manipulation functions. + o Fix many build issues when using the Microsoft C compiler. + o Remove a bash-ism in autogen.sh + o When calling event_del on a signal, restore the signal handler's previous value rather than setting it to SIG_DFL.

mechanism to execute a function when a specific event +on a file descriptor occurs or after a given time has passed. +.Pp +The +.Nm event +API needs to be initialized with +.Fn event_init +before it can be used. +.Pp +In order to process events, an application needs to call +.Fn event_dispatch . +This function only returns on error, and should replace the event core +of the application program. +.Pp +The function +.Fn event_set +prepares the event structure +.Fa ev +to be used in future calls to +.Fn event_add +and +.Fn event_del . +The event will be prepared to call the function specified by the +.Fa fn +argument with an +.Fa int +argument indicating the file descriptor, a +.Fa short +argument indicating the type of event, and a +.Fa void * +argument given in the +.Fa arg +argument. +The +.Fa fd +indicates the file descriptor that should be monitored for events. +The events can be either +.Va EV_READ , +.Va EV_WRITE , +or both, +indicating that an application can read or write from the file descriptor +respectively without blocking. +.Pp +The function +.Fa fn +will be called with the file descriptor that triggered the event and +the type of event which will be either +.Va EV_TIMEOUT , +.Va EV_SIGNAL , +.Va EV_READ , +or +.Va EV_WRITE . +Additionally, an event which has registered interest in more than one of the +preceeding events, via bitwise-OR to +.Fn event_set , +can provide its callback function with a bitwise-OR of more than one triggered +event. +The additional flag +.Va EV_PERSIST +makes an +.Fn event_add +persistent until +.Fn event_del +has been called. +.Pp +Once initialized, the +.Fa ev +structure can be used repeatedly with +.Fn event_add +and +.Fn event_del +and does not need to be reinitialized unless the function called and/or +the argument to it are to be changed. +However, when an +.Fa ev +structure has been added to libevent using +.Fn event_add +the structure must persist until the event occurs (assuming +.Fa EV_PERSIST +is not set) or is removed +using +.Fn event_del . +You may not reuse the same +.Fa ev +structure for multiple monitored descriptors; each descriptor +needs its own +.Fa ev . +.Pp +The function +.Fn event_add +schedules the execution of the +.Fa ev +event when the event specified in +.Fn event_set +occurs or in at least the time specified in the +.Fa tv . +If +.Fa tv +is +.Dv NULL , +no timeout occurs and the function will only be called +if a matching event occurs on the file descriptor. +The event in the +.Fa ev +argument must be already initialized by +.Fn event_set +and may not be used in calls to +.Fn event_set +until it has timed out or been removed with +.Fn event_del . +If the event in the +.Fa ev +argument already has a scheduled timeout, the old timeout will be +replaced by the new one. +.Pp +The function +.Fn event_del +will cancel the event in the argument +.Fa ev . +If the event has already executed or has never been added +the call will have no effect. +.Pp +The functions +.Fn evtimer_set , +.Fn evtimer_add , +.Fn evtimer_del , +.Fn evtimer_initialized , +and +.Fn evtimer_pending +are abbreviations for common situations where only a timeout is required. +The file descriptor passed will be \-1, and the event type will be +.Va EV_TIMEOUT . +.Pp +The functions +.Fn signal_set , +.Fn signal_add , +.Fn signal_del , +.Fn signal_initialized , +and +.Fn signal_pending +are abbreviations. +The event type will be a persistent +.Va EV_SIGNAL . +That means +.Fn signal_set +adds +.Va EV_PERSIST . +.Pp +In order to avoid races in signal handlers, the +.Nm event +API provides two variables: +.Va event_sigcb +and +.Va event_gotsig . +A signal handler +sets +.Va event_gotsig +to indicate that a signal has been received. +The application sets +.Va event_sigcb +to a callback function. +After the signal handler sets +.Va event_gotsig , +.Nm event_dispatch +will execute the callback function to process received signals. +The callback returns 1 when no events are registered any more. +It can return \-1 to indicate an error to the +.Nm event +library, causing +.Fn event_dispatch +to terminate with +.Va errno +set to +.Er EINTR . +.Pp +The function +.Fn event_once +is similar to +.Fn event_set . +However, it schedules a callback to be called exactly once and does not +require the caller to prepare an +.Fa event +structure. +This function supports +.Fa EV_TIMEOUT , +.Fa EV_READ , +and +.Fa EV_WRITE . +.Pp +The +.Fn event_pending +function can be used to check if the event specified by +.Fa event +is pending to run. +If +.Va EV_TIMEOUT +was specified and +.Fa tv +is not +.Dv NULL , +the expiration time of the event will be returned in +.Fa tv . +.Pp +The +.Fn event_initialized +macro can be used to check if an event has been initialized. +.Pp +The +.Nm event_loop +function provides an interface for single pass execution of pending +events. +The flags +.Va EVLOOP_ONCE +and +.Va EVLOOP_NONBLOCK +are recognized. +The +.Nm event_loopexit +function exits from the event loop. The next +.Fn event_loop +iteration after the +given timer expires will complete normally (handling all queued events) then +exit without blocking for events again. Subsequent invocations of +.Fn event_loop +will proceed normally. +The +.Nm event_loopbreak +function exits from the event loop immediately. +.Fn event_loop +will abort after the next event is completed; +.Fn event_loopbreak +is typically invoked from this event's callback. This behavior is analogous +to the "break;" statement. Subsequent invocations of +.Fn event_loop +will proceed normally. +.Pp +It is the responsibility of the caller to provide these functions with +pre-allocated event structures. +.Pp +.Sh EVENT PRIORITIES +By default +.Nm libevent +schedules all active events with the same priority. +However, sometimes it is desirable to process some events with a higher +priority than others. +For that reason, +.Nm libevent +supports strict priority queues. +Active events with a lower priority are always processed before events +with a higher priority. +.Pp +The number of different priorities can be set initially with the +.Fn event_priority_init +function. +This function should be called before the first call to +.Fn event_dispatch . +The +.Fn event_priority_set +function can be used to assign a priority to an event. +By default, +.Nm libevent +assigns the middle priority to all events unless their priority +is explicitly set. +.Sh THREAD SAFE EVENTS +.Nm Libevent +has experimental support for thread-safe events. +When initializing the library via +.Fn event_init , +an event base is returned. +This event base can be used in conjunction with calls to +.Fn event_base_set , +.Fn event_base_dispatch , +.Fn event_base_loop , +.Fn event_base_loopexit , +.Fn bufferevent_base_set +and +.Fn event_base_free . +.Fn event_base_set +should be called after preparing an event with +.Fn event_set , +as +.Fn event_set +assigns the provided event to the most recently created event base. +.Fn bufferevent_base_set +should be called after preparing a bufferevent with +.Fn bufferevent_new . +.Fn event_base_free +should be used to free memory associated with the event base +when it is no longer needed. +.Sh BUFFERED EVENTS +.Nm libevent +provides an abstraction on top of the regular event callbacks. +This abstraction is called a +.Va "buffered event" . +A buffered event provides input and output buffers that get filled +and drained automatically. +The user of a buffered event no longer deals directly with the IO, +but instead is reading from input and writing to output buffers. +.Pp +A new bufferevent is created by +.Fn bufferevent_new . +The parameter +.Fa fd +specifies the file descriptor from which data is read and written to. +This file descriptor is not allowed to be a +.Xr pipe 2 . +The next three parameters are callbacks. +The read and write callback have the following form: +.Ft void +.Fn "(*cb)" "struct bufferevent *bufev" "void *arg" . +The error callback has the following form: +.Ft void +.Fn "(*cb)" "struct bufferevent *bufev" "short what" "void *arg" . +The argument is specified by the fourth parameter +.Fa "cbarg" . +A +.Fa bufferevent struct +pointer is returned on success, NULL on error. +Both the read and the write callback may be NULL. +The error callback has to be always provided. +.Pp +Once initialized, the bufferevent structure can be used repeatedly with +bufferevent_enable() and bufferevent_disable(). +The flags parameter can be a combination of +.Va EV_READ +and +.Va EV_WRITE . +When read enabled the bufferevent will try to read from the file +descriptor and call the read callback. +The write callback is executed +whenever the output buffer is drained below the write low watermark, +which is +.Va 0 +by default. +.Pp +The +.Fn bufferevent_write +function can be used to write data to the file descriptor. +The data is appended to the output buffer and written to the descriptor +automatically as it becomes available for writing. +.Fn bufferevent_write +returns 0 on success or \-1 on failure. +The +.Fn bufferevent_read +function is used to read data from the input buffer, +returning the amount of data read. +.Pp +If multiple bases are in use, bufferevent_base_set() must be called before +enabling the bufferevent for the first time. +.Sh NON-BLOCKING HTTP SUPPORT +.Nm libevent +provides a very thin HTTP layer that can be used both to host an HTTP +server and also to make HTTP requests. +An HTTP server can be created by calling +.Fn evhttp_new . +It can be bound to any port and address with the +.Fn evhttp_bind_socket +function. +When the HTTP server is no longer used, it can be freed via +.Fn evhttp_free . +.Pp +To be notified of HTTP requests, a user needs to register callbacks with the +HTTP server. +This can be done by calling +.Fn evhttp_set_cb . +The second argument is the URI for which a callback is being registered. +The corresponding callback will receive an +.Va struct evhttp_request +object that contains all information about the request. +.Pp +This section does not document all the possible function calls; please +check +.Va event.h +for the public interfaces. +.Sh ADDITIONAL NOTES +It is possible to disable support for +.Va epoll , kqueue , devpoll , poll +or +.Va select +by setting the environment variable +.Va EVENT_NOEPOLL , EVENT_NOKQUEUE , EVENT_NODEVPOLL , EVENT_NOPOLL +or +.Va EVENT_NOSELECT , +respectively. +By setting the environment variable +.Va EVENT_SHOW_METHOD , +.Nm libevent +displays the kernel notification method that it uses. +.Sh RETURN VALUES +Upon successful completion +.Fn event_add +and +.Fn event_del +return 0. +Otherwise, \-1 is returned and the global variable errno is +set to indicate the error. +.Sh SEE ALSO +.Xr kqueue 2 , +.Xr poll 2 , +.Xr select 2 , +.Xr evdns 3 , +.Xr timeout 9 +.Sh HISTORY +The +.Nm event +API manpage is based on the +.Xr timeout 9 +manpage by Artur Grabowski. +The port of +.Nm libevent +to Windows is due to Michael A. Davis. +Support for real-time signals is due to Taral. +.Sh AUTHORS +The +.Nm event +library was written by Niels Provos. +.Sh BUGS +This documentation is neither complete nor authoritative. +If you are in doubt about the usage of this API then +check the source code to find out how it works, write +up the missing piece of documentation and send it to +me for inclusion in this man page. diff --git a/libevent/event.c b/libevent/event.c new file mode 100644 index 0000000..826b7db --- /dev/null +++ b/libevent/event.c @@ -0,0 +1,977 @@ +/* + * Copyright (c) 2000-2004 Niels Provos <provos@citi.umich.edu> + * All rights reserved. + * + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions + * are met: + * 1.

The libevent API provides a mechanism to execute a callback + function when a specific event occurs on a file descriptor or after a + timeout has been reached. Furthermore, libevent also support callbacks due + to signals or regular timeouts. + + libevent is meant to replace the event loop found in event driven network + servers. An application just needs to call event_dispatch() and then add or + remove events dynamically without having to change the event loop. + + Currently, libevent supports /dev/poll, kqueue(2), select(2), poll(2) and + epoll(4). It also has experimental support for real-time signals. The + internal event mechanism is completely independent of the exposed event API, + and a simple update of libevent can provide new functionality without having + to redesign the applications. As a result, Libevent allows for portable + application development and provides the most scalable event notification + mechanism available on an operating system. Libevent can also be used for + multi-threaded aplications; see Steven Grimm's explanation. Libevent should + compile on Linux, *BSD, Mac OS X, Solaris and Windows. + + @section usage Standard usage + + Every program that uses libevent must include the <event.h> header, and pass + the -levent flag to the linker. Before using any of the functions in the + library, you must call event_init() or event_base_new() to perform one-time + initialization of the libevent library. + + @section event Event notification + + For each file descriptor that you wish to monitor, you must declare an event + structure and call event_set() to initialize the members of the structure. + To enable notification, you add the structure to the list of monitored + events by calling event_add(). The event structure must remain allocated as + long as it is active, so it should be allocated on the heap. Finally, you + call event_dispatch() to loop and dispatch events. + + @section bufferevent I/O Buffers + + libevent provides an abstraction on top of the regular event callbacks. This + abstraction is called a buffered event. A buffered event provides input and + output buffers that get filled and drained automatically. The user of a + buffered event no longer deals directly with the I/O, but instead is reading + from input and writing to output buffers. + + Once initialized via bufferevent_new(), the bufferevent structure can be + used repeatedly with bufferevent_enable() and bufferevent_disable(). + Instead of reading and writing directly to a socket, you would call + bufferevent_read() and bufferevent_write(). + + When read enabled the bufferevent will try to read from the file descriptor + and call the read callback. The write callback is executed whenever the + output buffer is drained below the write low watermark, which is 0 by + default. + + @section timers Timers + + libevent can also be used to create timers that invoke a callback after a + certain amount of time has expired. The evtimer_set() function prepares an + event struct to be used as a timer. To activate the timer, call + evtimer_add(). Timers can be deactivated by calling evtimer_del(). + + @section timeouts Timeouts + + In addition to simple timers, libevent can assign timeout events to file + descriptors that are triggered whenever a certain amount of time has passed + with no activity on a file descriptor. The timeout_set() function + initializes an event struct for use as a timeout. Once initialized, the + event must be activated by using timeout_add(). To cancel the timeout, call + timeout_del(). + + @section evdns Asynchronous DNS resolution + + libevent provides an asynchronous DNS resolver that should be used instead + of the standard DNS resolver functions. These functions can be imported by + including the <evdns.h> header in your program. Before using any of the + resolver functions, you must call evdns_init() to initialize the library. To + convert a hostname to an IP address, you call the evdns_resolve_ipv4() + function. To perform a reverse lookup, you would call the + evdns_resolve_reverse() function. All of these functions use callbacks to + avoid blocking while the lookup is performed. + + @section evhttp Event-driven HTTP servers + + libevent provides a very simple event-driven HTTP server that can be + embedded in your program and used to service HTTP requests. + + To use this capability, you need to include the <evhttp.h> header in your + program. You create the server by calling evhttp_new(). Add addresses and + ports to listen on with evhttp_bind_socket(). You then register one or more + callbacks to handle incoming requests. Each URI can be assigned a callback + via the evhttp_set_cb() function. A generic callback function can also be + registered via evhttp_set_gencb(); this callback will be invoked if no other + callbacks have been registered for a given URI. + + @section evrpc A framework for RPC servers and clients + + libevents provides a framework for creating RPC servers and clients.
