Nick Mathewson 76cd2b70 2009-11-27T16:44:47 Stop passing EVTHREAD_READ and EVTHREAD_WRITE to non-rw locks. Previously, our default lock model kind of assumed that every lock was potentially a read-write lock. This was a poor choice, since read-write locks are far more expensive than regular locks, and so the lock API should only use them when we can actually take advantage of them. Neither our pthreads or win32 lock implementation provided rw locks. Now that we have a way (not currently used!) to indicate that we really want a read-write lock, we shouldn't actually say "lock this for reading" or "lock this for writing" unless we mean it.
Nick Mathewson 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
Nick Mathewson ac633aeb 2009-11-05T21:22:23 Fix some build warnings on MSVC, mostly related to signed/unsigned comparisons. svn:r1510
Nick Mathewson 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
Nick Mathewson a84c87d7 2009-11-02T19:51:26 Refactor IOCP callback interface Chris Davis points out that GetQueuedCompletionStatus sometimes returns false not to report "No events for you!" but instead to report "An overlapped operation failed." Add a way to tell an event_overlapped that its operation failed. svn:r1490
Nick Mathewson 2e36dbe1 2009-10-26T20:00:43 Use EVUTIL_ASSERT() consistently instead of assert. svn:r1464
Nick Mathewson 5b5b880b 2009-07-28T19:41:39 Various MSVC cleanups from Brodie Thiesfield. svn:r1385
Nick Mathewson 0b22ca19 2009-05-22T19:11:48 Use ev_ssize_t in place of ssize_t *everywhere*. svn:r1309
Nick Mathewson 7a844735 2009-05-22T17:20:05 Fix some small win32 build issues on trunk. svn:r1306
Nick Mathewson 8997f234 2009-05-21T20:59:00 Use the native "struct iovec" as our "struct evbuffer_iovec" when available, so we do not need to copy more pointers than necessary. svn:r1299
Nick Mathewson 23243b8a 2009-05-19T21:39:35 Replace reserve/commit with new iovec-based interface. Add a new evbuffer_peek. svn:r1296
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 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
Nick Mathewson af8b8222 2009-05-05T15:30:58 Add missing include to buffer_iocp.c svn:r1275
Nick Mathewson 5a3eddf0 2009-05-02T16:24:05 Use fewer _compat.h headers in our own code. svn:r1268
Nick Mathewson e865eb93 2009-05-01T00:54:14 More msvc build tweaks. svn:r1262
Nick Mathewson efc24f7c 2009-04-30T20:47:38 Get launch_read and launch_write to (apparently) work. svn:r1258
Nick Mathewson 23121bfb 2009-04-30T19:56:23 Fix a reversed check in upcast_evbuffer svn:r1257
Nick Mathewson 838d0a81 2009-04-17T06:55:08 Document many internal functions and pieces of code. svn:r1181
Nick Mathewson 433e2339 2009-04-17T06:54:28 Remove long copy-and-paste section full of windows api notes. svn:r1180
Nick Mathewson 93d4f884 2009-04-14T20:11:10 Make buffer iocp stuff compile happily svn:r1174
Nick Mathewson ca737ff3 2009-04-13T18:29:31 Add draft (nonworking) versions of iocp code to hack on more. svn:r1172
