Nick Mathewson bd26bace 2009-08-11T19:47:46 When running with deferred callbacks, always send the "connected" event before any read/write events, and send timeout/error/eof events after. svn:r1413
Nick Mathewson 7c688dd9 2009-07-31T14:41:45 New function to expose bufferevent.enabled svn:r1401
Nick Mathewson 709c21c4 2009-07-28T04:03:57 Bufferevent support for openssl. This code adds a new Bufferevent type that is only compiled when the openssl library is present. It supports using an SSL object and an event alert mechanism, which can either be an fd or an underlying bufferevent. There is still more work to do: the unit tests are incomplete, and we need to support flush and shutdown much better. Sometimes events are generated needlessly: this will hose performance. There's a new encrypting proxy in sample/le-proxy.c. This code has only been tested on OSX, and nowhere else. svn:r1382
Nick Mathewson b06b2649 2009-07-26T01:29:39 Make "deferred callback queue" independent of event_base. This way, we can more easily have an IOCP bufferevent implementation that does not need an event_base at all. Woot. svn:r1381
Nick Mathewson a62283a9 2009-07-17T17:46:17 Always hold a reference to a bufferevent when calling its callbacks. Rationale: we hold a lock on the bufferevent when its callbacks are executing, so we need to release the lock afterwards. But the callback might free the bufferevent, so unless we're holding a reference on the bufferevent, the lock might not be there for us to release. svn:r1347
Nick Mathewson a501d683 2009-07-10T19:34:00 Add a lock/unlock pair inside the event callbacks in bufferevents. This fixes part of bug 2800642, I believe, though there is still a general race condition in multithreaded use of events that we need to think about. svn:r1337
Nick Mathewson 5232cfa3 2009-05-25T23:11:20 Consistently say "eventcb" instead of "errorcb" svn:r1316
Nick Mathewson 34574db0 2009-05-25T23:10:23 Add a generic mechanism to implement timeouts in bufferevents. Paired and asynchronous bufferevents didn't do timeouts, and filtering bufferevents gave them funny semantics. Now they all should all work in a way consistent with what socket bufferevents do now: a [read/write] timeout triggers if [reading/writing] is enabled, and if the timeout is set, and the right amount of time passes without any data getting [added to the input buffer/drained from the output buffer]. svn:r1314
Nick Mathewson 59484297 2009-05-20T12:24:13 Fix a deadlock: there were some LOCKs that should have been UNLOCKs. Resolves bug 2794244 svn:r1298
Nick Mathewson bba69e03 2009-05-15T20:23:59 New semantics for evbuffer_cb_set_flags(). Previously, set_flags() would replace all previous user-visible flags. Now it just sets the flags, and there is a clear_flags() function to clear other flags. svn:r1293
Nick Mathewson 31d89f27 2009-05-13T20:37:21 Add a "ctrl" mechanism to bufferevents for property access. OpenSSL uses something like this to implement get/set access for properties on its BIOs, so that it doesn't need to add a pair of get/set functions to the vtable struct for every new abstract property it provides an accessor for. Doing this lets us make bufferevent_setfd abstract, and implement an abstract bufferevent_getfd. svn:r1284
Nick Mathewson 83f46e51 2009-05-13T20:36:56 Do not use the "evbuffer_" prefix to denote parts of bufferevents. This is a bit of an interface doozy, but it's really needed in order to be able to document this stuff without apologizing it. This patch does the following renamings: evbuffercb -> bufferevent_data_cb everrorcb -> bufferevent_event_cb EVBUFFER_(READ,WRITE,...) -> BEV_EVENT_(...) EVBUFFER_(INPUT,OUTPUT) -> bufferevent_get_(input,output) All the old names are available in event2/bufferevent_compat.h svn:r1283
Nick Mathewson b69d03b5 2009-05-05T14:18:14 Add a constructor for bufferevent_async. svn:r1274
Nick Mathewson 5a3eddf0 2009-05-02T16:24:05 Use fewer _compat.h headers in our own code. svn:r1268
Nick Mathewson 24607a39 2009-04-29T20:48:43 Note a place we might do better about lock releasing. svn:r1252
Nick Mathewson a98a512b 2009-04-17T23:12:34 Add a generic way for any bufferevent to make its callback deferred svn:r1197
Nick Mathewson 91039e4d 2009-04-17T06:57:38 Add reference counts to bufferevents. svn:r1189
Nick Mathewson a8f6d961 2009-04-17T06:56:09 Actually stop using EVBUFFER_LENGTH/DATA, and move them to buffer_compat.h svn:r1183
Nick Mathewson 915193e7 2009-04-13T03:17:19 Locking support for bufferevents. svn:r1170
Nick Mathewson 1becc4c4 2009-04-13T03:08:11 Refactor new elements of bufferevent into bufferevent_private structure This way we don't expose more of a bufferevent than we need to. One motivation is to make it easier to automatically get deferred callbacks with a bufferevent without exposing the deferred_cb structure. svn:r1169
Nick Mathewson 6a18f4b0 2009-04-05T04:15:01 Munge the read_suspended flag before re-enabling reads on the underlying bufferevent. This makes it so the enabled thing has some idea whether reads are supposed to be suspended or not. svn:r1136
Nick Mathewson f1b1bad4 2009-04-03T14:27:03 Make the new evbuffer callbacks use a new struct-based interface. The old interface would fail pretty hard when we had to batch up multiple adds and drains in a single call. svn:r1131
Nick Mathewson ea4b8724 2009-02-02T19:22:13 checkpoint work on big bufferevent refactoring svn:r1095
Nick Mathewson b85b710c 2009-01-27T22:34:36 Update copyright statements to reflect the facts that: a) this is 2009 b) niels and nick have been comaintainers for a while c) saying "all rights reserved" when you then go on to explicitly disclaim some rights is sheer cargo-cultism. svn:r1065
Nick Mathewson 8889a770 2009-01-27T22:30:46 Replace all use of config.h with event-config.h. svn:r1064
Nick Mathewson 9993137c 2009-01-27T21:10:31 Remove all trailing whitespace in all the source files. svn:r1063
Nick Mathewson ec2f4cbc 2009-01-23T01:35:57 Move obsolete evbuffer function into include/event2/buffer_compat.h svn:r1043
Nick Mathewson 20c20466 2009-01-22T17:48:27 Use EV_PERSIST in bufferevents for efficiency and simplicity. svn:r1038
Nick Mathewson 169321c9 2009-01-13T20:26:37 Rename four internal headers to follow the -internal.h convention. svn:r1000
Nick Mathewson 81ab45ad 2009-01-13T19:20:04 Use new EVUTIL_ERR_*_RETRIABLE macros when we're testing an errno for blocking. Previously, we used inconsistent and incompletely ported ifdefs. (We don't use these macros in platform-specific files like evpoll.c, since they don't need to work on win32.) svn:r995
Niels Provos 5e905c9d 2008-07-17T14:09:07 if we change the timeouts on bufferevents, we might have to readd pending events svn:r911
Nick Mathewson 8acb80b4 2008-05-08T22:51:39 r15551@tombo: nickm | 2008-05-08 14:49:20 -0400 Use _get_ convention for new accessor functions. (These are all new ones as of 2.0, I believe). svn:r799
Niels Provos 36d7ab50 2008-05-04T18:31:21 trust in naming: rename evbuffer.c to bufferevent.c svn:r767
