It has a new callback in evhttp for<br/> reporting errors during a request, a new feature for allowing evdns to<br/> not keep the event_base looping when there are no requests inflight, and<br/> example code for writing an https client.<br/><br/> Libevent 2.1.3-alpha also has an important new (experimental) event<br/> finalization feature to allow safe event teardown in multithreaded<br/> programs.

Ths log below tries to organize features by rough area of<br/> effect. It omits a few commits which were pure bugfixes on other commits<br/> listed below. For more detail, see the git changelogs. For more<br/> insight, see the "whatsnew-2.1.txt" document included in the Libevent<br/> 2.1.2-alpha distribution.<br/><br/> Libevent 2.1.2-alpha also includes all changes made in 2.0.19-stable<br/> through 2.0.21-stable inclusive.<br/><br/> Performance (core):<br/> o Replace pipe-based notification with EVFILT_USER where possible. This<br/> should make multithreaded programs on OSX and *BSD alert the main thread a<br/> little faster. (53a07fe)<br/> o Make th_base_lock nonrecursive. (9cd5acb)<br/><br/> New/Changed API Functions:<br/> o New event_get_priority() function to return an event's priority (f90e255)<br/> o Add a bufferevent_get_priority() function (bd39554)<br/> o Add an event_base_loopcontinue() to tell Libevent to rescan for more<br/> events right away (7d6aa5e)<br/> o Add a new callback to get called on evbuffer_file_segment free<br/> (e9f8feb yangacer, 64051b9)<br/> o Expose event_base_foreach_event() as a public API.

(The old name<br/> should still work.) (07e132e)<br/> o Add missing implementation for event_enable_debug_logging (3b3e21d)<br/><br/> PORTABLE MONOTONIC TIMERS:<br/><br/> Libevent 2.1.2 includes internal support for monotonic timers on<br/> (nearly) all supported platforms, including Windows, and OSX. Libevent<br/> applications should now be more resilient to jumps forwards or backwards<br/> in the system clock. Also, on Linux systems with epoll, we now<br/> optionally support microsecond-level timeouts (whereas epoll only<br/> supports millisecond-precision timeouts).<br/><br/> o Use mach_absolute_time() for monotonic clock support on OSX. (b8fd6f9)<br/> o Do not track use_monotonic field when is no monotonic clock (cb653a0)<br/> o EVENT_BASE_FLAG_PRECISE_TIMER indicates we want fine timer precision<br/> (ddd69d3)<br/> o On Linux, use CLOCK_MONOTONIC_COARSE by default (55780a7)<br/> o Implement a GetTickCount-based monotonic timer for Windows (d5e1d5a)<br/> o Refactor monotonic timer handling into a new type and set of<br/> functions; add a gettimeofday-based ratcheting implementation (f5e4eb0)<br/> o Add EVENT_PRECISE_TIMER environment var for selecting precise-but-slow<br/> timer (a2598ec)<br/> o Implement fast/precise monotonic clocks on Windows (2c47045)<br/> o Simple unit tests for monotonic timers (630f077)<br/> o Improve the monotonic-time unit test: make it check the step size (7428c78)<br/> o When PRECISE_TIMERS is set with epoll, use timerfd for microsecond<br/> precision (26c7582)<br/> o Split out time-related evutil functions into a new evutil_time.c (c419485)<br/> o Split out time-related prototypes into time-internal.h (71bca50)<br/> o Add evutil_time.obj to Makefile.nmake (0ba0683)<br/> o Avoid giving a spurious warning when timerfd support is unavailable<br/> (1aaf9f0 Dave Hart)<br/> o Make test_evutil_monotonic a little more tolerant (def3b83)<br/> o Avoid unused-var warning on systems with clock_gettime but without<br/> CLOCK_MONOTONIC_COARSE (9be5468)<br/><br/>EVENT_BASE_ONCE LEAKS:<br/> If a callback added by event_base_once() is never invoked, Libevent no<br/> longer leaks internal memory.<br/><br/> o Free dangling event_once objects on event_base_free() (c17dd59)<br/> o Add a unit test in which an event is created with event_base_once()<br/> but never fires (4343edf)<br/><br/>TESTING SUPPORT, FIXES AND IMPROVEMENTS:<br/><br/> Libevent now disables by default its unit tests that would touch the<br/> network, or that tend to fail on heavily-loaded systems. To re-enable<br/> them, invoke the ./test/regress program with the @all alias.<br/><br/> o Simplify test.sh code significantly.
