1ac5b230	2010-11-09 15:18:59	Only clear underlying callbacks when the user hasn't reset them.
fc7b1b00	2010-11-09 11:43:47	When closing a filtering bufferevent, clear callbacks on the underlying bufferevent Previously, if BEV_OPT_CLOSE_ON_FREE wasn't set on a bufferevent_filter or a filtering bufferevent_openssl, when we went to free the filtering bufferevent, we'd leave the underlying bufferevent unchanged. That's not so good, since the callbacks are set to activate stuff in the filtering bufferevent that we're about to free. Instead, set all the callbacks to NULL.
ac27eb82	2010-10-08 00:59:02	Correct logic on disabling underlying bufferevents when disabling a filter Previously, whenever writing was disabled on a bufferevent_filter (or a filtering SSL bufferevent), we would stop writing on the underlying bufferevent. This would make for trouble, though, since if you implemented common patterns like "stop writing once data X has been flushed", your bufferevent filter would disable the underlying bufferevent after the data was flushed to the underlying bufferevent, but before actually having it written to the network. Now, we have filters leave their underlying bufferevents enabled for reading and writing for reading and writing immediately. They are not disabled, unless the user wants to disable them, which is now allowed. To handle the case where we want to choke reading on the underlying bufferevent because the filter no longer wants to read, we use bufferevent_suspend_read(). This is analogous to the way that we use bufferevent_suspend_write() to suspend writing on a filtering bufferevent when the underlying bufferevent's output buffer has hit its high watermark.
ec347b92	2010-07-07 16:45:03	Move event-config.h to include/event2 This change means that all required include files are in event2, and all files not in event2/* are optional.
657d1b6d	2010-03-13 01:06:57	Set mem_offset for every bufferevent type
f1bc125e	2010-03-12 23:00:49	Improve robustness for refcounting Document that we do intend to double-decref underlying bufferevents under some circumstances. Check to make sure that we don't decref past 0.
17efc1cd	2010-03-04 01:25:51	Update all our copyright notices to say "2010"
d3288293	2010-02-20 18:44:35	Provide consistent, tested semantics for bufferevent timeouts The different bufferevent implementations had different behavior for their timeouts. Some of them kept re-triggering the timeouts indefinitely; some disabled the event immediately the first time a timeout triggered. Some of them made the timeouts only count when the bufferevent was actively trying to read or write; some did not. The new behavior is modeled after old socket bufferevents, since they were here first and their behavior is relatively sane. Basically, each timeout disables the bufferevent's corresponding read or write operation when it fires. Timeouts are stopped whenever we suspend writing or reading, and reset whenever we unsuspend writing or reading. Calling bufferevent_enable resets a timeout, as does changing the timeout value.
4faeaea9	2010-02-19 03:39:50	Clean up formatting: function/keyword spacing consistency. - Keywords always have a space before a paren. Functions never do. - No more than 3 blank lines in a row.
e5bbd40a	2010-02-18 17:41:15	Clean up formatting: use tabs, not 8-spaces, to indent.
8fdf09c0	2010-02-18 17:08:50	Clean up formatting: Disallow space-before-tab.
2e8eeea3	2009-12-29 19:50:03	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.
a773df54	2009-12-18 16:24:41	Fix a segfault when freeing SSL bufferevents in an unusual order Have container bufferevents hold a reference to their underlying bufferevents. (Commit message and minor revisions by nickm.)
784b8773	2009-11-06 21:46:57	We do not work any more without an event-config.h; stop pretending that it is meaningful to check for HAVE_CONFIG_H svn:r1516
2e36dbe1	2009-10-26 20:00:43	Use EVUTIL_ASSERT() consistently instead of assert. svn:r1464
b73ad7bc	2009-10-21 18:48:22	Treat the bitwise OR of two enum values as an int. This makes our interfaces usable from C++, which doesn't believe you can say "bufferevent_socket_nase(base, -1, BEV_OPT_CLOSE_ON_FREE\|BEV_OPT_DEFER_CALLBACKS)" but which instead would demand "static_cast<bufferevent_options>(BEV_OPT_CLOSE_ON_FREE\| BEV_OPT_DEFER_CALLBACKS))" for the last argument. Diagnosis and patch from Chris Davis. svn:r1456
e3fd294a	2009-10-16 13:19:57	Spelling fixes in comments and strings. svn:r1445
709c21c4	2009-07-28 04:03:57	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
a62283a9	2009-07-17 17:46:17	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
5232cfa3	2009-05-25 23:11:20	Consistently say "eventcb" instead of "errorcb" svn:r1316
34574db0	2009-05-25 23:10:23	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
0b22ca19	2009-05-22 19:11:48	Use ev_ssize_t in place of ssize_t everywhere. svn:r1309
31d89f27	2009-05-13 20:37:21	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
5a3eddf0	2009-05-02 16:24:05	Use fewer _compat.h headers in our own code. svn:r1268
eda27f95	2009-04-19 20:54:12	Update copyright notices, add some missing license statements svn:r1208
a98a512b	2009-04-17 23:12:34	Add a generic way for any bufferevent to make its callback deferred svn:r1197
a8f6d961	2009-04-17 06:56:09	Actually stop using EVBUFFER_LENGTH/DATA, and move them to buffer_compat.h svn:r1183
915193e7	2009-04-13 03:17:19	Locking support for bufferevents. svn:r1170
1becc4c4	2009-04-13 03:08:11	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
23085c92	2009-04-10 15:01:31	Add a linked-pair abstraction to bufferevents. The new bufferevent_pair abstraction works like a set of buferevent_sockets connected by a socketpair, except that it doesn't require a socketpair, and therefore doesn't need to get the kernel involved. It's also a good way to make sure that deferred callbacks work. It's a good use case for deferred callbacks: before I implemented them, the recursive relationship between the evbuffer callback and the read callback would make the unit tests overflow the stack. svn:r1152
f1b1bad4	2009-04-03 14:27:03	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
ac36f404	2009-02-11 05:17:27	oops; coding too quickly on nil-filter patch. Caught by niels. svn:r1115
20f809ce	2009-02-10 19:39:12	Make default (nil) filter use evbuffer_remove_buffer to respect the high-water mark of the target buffer. svn:r1109
3502a472	2009-02-02 21:24:04	convert new bufferevent_*.c files to event-config.h only. svn:r1097
ea4b8724	2009-02-02 19:22:13	checkpoint work on big bufferevent refactoring svn:r1095
