2c470452 2012-04-23 13:33:25 Implement fast/precise monotonic clocks on Windows This uses code from libutp, which was released under the MIT license; see evutil_time.c and LICENSE changes.
a2598ec6 2012-04-23 13:56:00 Add EVENT_PRECISE_TIMER environment var for selecting precise-but-slow timer
f5e4eb05 2012-04-20 13:14:10 Refactor monotonic timer handling into a new type and set of functions; add a gettimeofday-based ratcheting implementation Now, event.c can always assume that we have a monotonic timer; this makes event.c easier to write.

dfd808cb 2012-04-19 00:25:12 If time has jumped so we'd reschedule a periodic event in the past, schedule it for the future instead Fixes an issue reported on libevent-users in the thread "a dead looping bug when changing system time backward". Previously, if time jumped forward 1 hour[*] and we had a one-second periodic timer event, that event would get invoked 3600 times. That's almost certainly not what anybody wants. In a future version of Libevent, we should expose the amount of time that the callbac kwould have been invoked somehow. [*] Forward time jumps can happen with nonmonotonic clocks, or with clocks that jump on suspend/resume. It can also happen from Libevent's point of view if the user exits from event_base_loop() and doesn't call it again for a while.

d5e1d5ad 2012-04-17 15:16:08 Implement a GetTickCount-based monotonic timer for Windows
55780a70 2012-04-17 13:09:49 On Linux, use CLOCK_MONOTONIC_COARSE by default You can make it use CLOCK_MONOTONIC again by setting the EVENT_BASE_FLAG_PRECISE_TIMER flag in the event_config.
ddd69d39 2012-04-17 13:04:02 EVENT_BASE_FLAG_PRECISE_TIMER indicates we want fine timer precision There are a bunch of backends that can give us a reasonably good monotonic timer quickly, or a very precise monotonic timer less quickly. For example, Linux has CLOCK_MONOTONIC_COARSE (1msec precision), which is over twice as fast as CLOCK_MONOTONIC. Since epoll only lets you wait with 1msec precision, CLOCK_MONOTONIC_COARSE is a clear win. On Windows, you've got GetTickCount{,64}() which is fast, and QueryPerformanceCounter, which is precise but slow. Note that even in the cases where the underlying timer claims to have nanosecond resolution, we're still not exposing that via Libevent. Note also that "Precision" isn't the same as "Resolution" or "Accuracy". A timer's precision is the smallest change that the clock will register; a timer's resolution is the fineness of its underlying representation; a timer's accuracy is how much it drifts with respect to "Real Time", whatever that means. (Terms and definitions from PEP 418.)
1fbef7d5 2012-04-17 12:44:39 Move use_monotonic and friends into event_base The use_monotonic field used to be a static field set up at library setup. Unfortunately, this makes it hard to give the user a way to make speed/accuracy tradeoffs about time. Moving it into event_base should let the clock implementation become configurable.
b62b31f1 2012-04-11 21:33:27 Work-around a stupid gcov-breaking bug in OSX 10.6 This only affects the unit tests. Fix found at http://rachelbythebay.com/w/2011/07/12/forkcrash/
53a07fe2 2010-09-17 00:34:13 Replace pipe-based notification with EVFILT_USER where possible Sufficiently recent kqueue implementations have an EVFILT_USER filter that we can use to wake up an event base from another thread. When it's supported, we now use this mechanism rather than our old (pipe-based) mechanism. This should save some time and complications on newer OSX and freebsds.

0af23d59 2012-04-09 11:33:08 Merge branch '21_weakrand'
3aa44159 2012-04-09 11:30:46 Tweak the new evutil_weakrand_() code Make its state actually get seeded. Document it more thoroughly. Turn its state into a structure. Fix a bug in evutil_weakrand_range_() where it could return the top of the range. Change its return type to ev_int32_t. Add a quick unit test to make sure that the value of evutil_weakrand_range_() is in range.
e86af4b7 2012-04-09 10:46:32 Change evutil_weakrand_() to avoid platform random() This change allows us to avoid perturbing the platform's random(), and to avoid hitting locks on random() in the platform's libc. evutil_weakrand_() is, well, weak, so we choose here an algorithm that favors speed over a number of other possibly desirable properties. We're using a linear congruential generator, and taking our parameters from those shared by the OpenBSD random() implementation, and Glibc's fastest random() implementation. The low bits of a LCG of modulus 2^32 are (notoriously) less random than the higher bits. So to generate a random value in a range, using the % operator is no good; we ought to divide. We add an evutil_weakrand_range_() function to do that. This code also changes the interface of evutil_weakrand_() so that it now manipulates an explicit seed, rather than having the seed in a static variable. This change enables us to use existing locks to achieve thread-safety, rather than having to rely on an additional lock. (Patch by Nicholas Marriott; commit message by Nick Mathewson.)

d1a03b2f 2012-04-03 18:31:08 Backport: provide EVENT_LOG_* names, and deprecate _EVENT_LOG_* This is a partial backport of cb9da0bf and a backport of c9635349. Because C doesn't like us to declare identifiers starting with an underscore, Libevent 2.1 has renamed every such identifier. The only change that affects a public API is that the _EVENT_LOG_* macros have been renamed to start with EVENT_LOG instead. The old names are still present, but deprecated. I'm doing this backport because it represents the deprecation of a Libevent 2.0 interface, and folks should have the opportunity to write code that isn't deprecated and works with both 2.0 and 2.1.

8c36acd0 2012-03-23 18:42:56 Fix a nasty bug in event_queue_reinsert_timeout() What was I thinking? The old function could handle heap-to-heap transitions, and transitions within the same common timeout queue, but it completely failed to handle heap/queue transitions, or transitions between timeout queues. Now, alas, it's complicated. I should look hard at the assembly here to see if it's actually better than the alternatives.
7afe48aa 2012-03-23 17:56:23 Add a unit test for event_base_dump_events() This function uses a C program to generate its output, and then uses a Python program to check it for correctness. On systems without Python, we just make sure that the C program doesn't crash. It's likely that we should be requiring some particular python version. This is an alpha, though: I'm sure somebody will tell us which.

041ca00c 2011-07-12 12:25:41 Add a new libevent_global_shutdown() to free all globals before exiting. Mark Ellzey added a function libevent_shutdown() which calls a set of private functions: * event_free_globals() * event_free_debug_globals() * event_free_debug_globals_locks() * event_free_evsig_globals() * evsig_free_globals() * evsig_free_globals_locks() * evutil_free_globals() * evutil_free_secure_rng_globals() * evutil_free_secure_rng_globals_lock() Nick tweaked this libevent global shutdown code: - rename the function to emphasize that it's for global resources - write more in the doxygen - make function brace style consistent - add a missing void in a function definition.
