ba2945f9	2010-01-06T17:59:44	Merge branch 'ratelimit' Conflicts: bufferevent_async.c
165d30e3	2009-12-30T14:29:56	Fix compilation of rate-limiting code on win32.
2e8eeea3	2009-12-29T19:50:03	Fix crash bugs when a bufferevent's eventcb is not set. In many places throughout the code, we called _bufferevent_run_eventcb without checking whether the eventcb was actually set. This would work fine when the bufferevent's callbacks were deferred, but otherwise the code would segfault. Strangely, we always remembered to check before calling the _bufferevent_run_{read,write}cb functions. To prevent similar errors in the future, all of _buferevent_run_{read,write,event}cb now check to make sure the callback is actually set before invoking or deferring the callback. This patch also removes the now-redundant checks for {read,write}cb.
737c9cd8	2009-11-27T13:16:54	Rate-limiting for bufferevents; group and individual limits are supported. The fairness algorithms are not the best, not every bufferevent type is supported, and some of the locking tricks here are simply absurd. Still, this code should be a good first step.
d7d1f1da	2009-11-17T20:31:09	Move responsibility for IOCP callback into bufferevent_async. This patch from Chris Davis saves some callback depth, and adds proper ref-counting to bufferevents when there's a deferred evbuffer callback inflight. It could use a couple more comments to really nail down what its invariants are. svn:r1543
86db1c85	2009-11-04T05:19:26	Commit ConnectEx code to get connect working with async bufferevents. This is code by Chris Davis, with changes to get the unit tests failing less aggressively. The unit tests for this code do not completely pass yet; Chris is looking into that. If they aren't passing by the next release, I'll turn off this code. svn:r1499
2e36dbe1	2009-10-26T20:00:43	Use EVUTIL_ASSERT() consistently instead of assert. svn:r1464
879420a7	2009-10-23T22:00:29	Expose a narrow window to the IOCP code. svn:r1459
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
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
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
a8bcbfd4	2009-05-06T02:33:37	Fix bufferevent_async to use lock/unlock, not unlock/unlock. You do NOT want to know what windows does when you unlock a lock that is already unlocked. svn:r1278
fe47003d	2009-05-05T16:52:37	Make unit tests for bufferevent_async compile and _almost_ work. Either I need to make the callbacks get deferred in a base with no events (doable), or I need to make it okay to call launch_read from inside the callback for read (tricky). svn:r1277
02801e5b	2009-05-05T15:36:28	Add a trival start of a be_async test. svn:r1276
b69d03b5	2009-05-05T14:18:14	Add a constructor for bufferevent_async. svn:r1274
5a3eddf0	2009-05-02T16:24:05	Use fewer _compat.h headers in our own code. svn:r1268
1aebcd50	2009-05-01T01:42:33	Initial core implementation of bufferevent_async.c svn:r1263
