Changes in version 2.1.3-alpha (1 May 2013)
|
|
|
|
Libevent 2.1.3-alpha fixes various bugs, adds new unit tests, and cleans
|
|
up the code in a couple of places. It has a new callback in evhttp for
|
|
reporting errors during a request, a new feature for allowing evdns to
|
|
not keep the event_base looping when there are no requests inflight, and
|
|
example code for writing an https client.
|
|
|
|
Libevent 2.1.3-alpha also has an important new (experimental) event
|
|
finalization feature to allow safe event teardown in multithreaded
|
|
programs. This ought to fix the longstanding bug with deadlocks in
|
|
multithreaded use of SSL-based bufferevents that some people have been
|
|
experiencing since Libevent 2.0.

Changes in version 2.1.2-alpha (18 Nov 2012)
|
|
|
|
Libevent 2.1.2-alpha includes more portable for monotonic timers,
|
|
refactors much of Libevent's internal and external infrastructure,
|
|
closes some longstanding gaps in the interface, makde other
|
|
improvements. Ths log below tries to organize features by rough area of
|
|
effect. It omits a few commits which were pure bugfixes on other commits
|
|
listed below. For more detail, see the git changelogs. For more
|
|
insight, see the "whatsnew-2.1.txt" document included in the Libevent
|
|
2.1.2-alpha distribution.
|
|
|
|
Libevent 2.1.2-alpha also includes all changes made in 2.0.19-stable
|
|
through 2.0.21-stable inclusive.
|
|
|
|
Performance (core):
|
|
o Replace pipe-based notification with EVFILT_USER where possible. This
|
|
should make multithreaded programs on OSX and *BSD alert the main thread a
|
|
little faster. (53a07fe)
|
|
o Make th_base_lock nonrecursive. (9cd5acb)
|
|
|
|
New/Changed API Functions:
|
|
o New event_get_priority() function to return an event's priority (f90e255)
|
|
o Add a bufferevent_get_priority() function (bd39554)
|
|
o Add an event_base_loopcontinue() to tell Libevent to rescan for more
|
|
events right away (7d6aa5e)
|
|
o Add a new callback to get called on evbuffer_file_segment free
|
|
(e9f8feb yangacer, 64051b9)
|
|
o Expose event_base_foreach_event() as a public API. (84fd6d7 Roman
|
|
Puls, 232055e, ffe1643)
|
|
o Add an event_remove_timer() to remove timer on an event without
|
|
deleting it (e3b2e08)
|
|
o Make bufferevent_set_timeouts(bev, NULL, NULL) have plausible
|
|
semantics (9dee36b)
|
|
o Rename event_enable_lock_debuging() to ..._debugging(). (The old name
|
|
should still work.) (07e132e)
|
|
o Add missing implementation for event_enable_debug_logging (3b3e21d)
|
|
|
|
PORTABLE MONOTONIC TIMERS:
|
|
|
|
Libevent 2.1.2 includes internal support for monotonic timers on
|
|
(nearly) all supported platforms, including Windows, and OSX. Libevent
|
|
applications should now be more resilient to jumps forwards or backwards
|
|
in the system clock. Also, on Linux systems with epoll, we now
|
|
optionally support microsecond-level timeouts (whereas epoll only
|
|
supports millisecond-precision timeouts).
|
|
|
|
o Use mach_absolute_time() for monotonic clock support on OSX. (b8fd6f9)
|
|
o Do not track use_monotonic field when is no monotonic clock (cb653a0)
|
|
o EVENT_BASE_FLAG_PRECISE_TIMER indicates we want fine timer precision
|
|
(ddd69d3)
|
|
o On Linux, use CLOCK_MONOTONIC_COARSE by default (55780a7)
|
|
o Implement a GetTickCount-based monotonic timer for Windows (d5e1d5a)
|
|
o Refactor monotonic timer handling into a new type and set of
|
|
functions; add a gettimeofday-based ratcheting implementation (f5e4eb0)
|
|
o Add EVENT_PRECISE_TIMER environment var for selecting precise-but-slow
|
|
timer (a2598ec)
|
|
o Implement fast/precise monotonic clocks on Windows (2c47045)
|
|
o Simple unit tests for monotonic timers (630f077)
|
|
o Improve the monotonic-time unit test: make it check the step size (7428c78)
|
|
o When PRECISE_TIMERS is set with epoll, use timerfd for microsecond
|
|
precision (26c7582)
|
|
o Split out time-related evutil functions into a new evutil_time.c (c419485)
|
|
o Split out time-related prototypes into time-internal.h (71bca50)
|
|
o Add evutil_time.obj to Makefile.nmake (0ba0683)
|
|
o Avoid giving a spurious warning when timerfd support is unavailable
|
|
(1aaf9f0 Dave Hart)
|
|
o Make test_evutil_monotonic a little more tolerant (def3b83)
|
|
o Avoid unused-var warning on systems with clock_gettime but without
|
|
CLOCK_MONOTONIC_COARSE (9be5468)
|
|
|
|
EVENT_BASE_ONCE LEAKS:
|
|
If a callback added by event_base_once() is never invoked, Libevent no
|
|
longer leaks internal memory.
|
|
|
|
o Free dangling event_once objects on event_base_free() (c17dd59)
|
|
o Add a unit test in which an event is created with event_base_once()
|
|
but never fires (4343edf)
|
|
|
|
TESTING SUPPORT, FIXES AND IMPROVEMENTS:
|
|
|
|
Libevent now disables by default its unit tests that would touch the
|
|
network, or that tend to fail on heavily-loaded systems. To re-enable
|
|
them, invoke the ./test/regress program with the @all alias.
|
|
|
|
o Simplify test.sh code significantly. (9b856fd Ross Lagerwall)
|
|
o Make all tests that hit the network disabled by default (f2cea87)
|
|
o Avoid a resource leak on error in http client benchmark (ea92fba)
|
|
o Update to latest tinytest (911b4f0349377) (ef7c4f7)
|
|
o Avoid (unlikely) overflow in bench_httpclient.c (5671033)
|
|
o Shave 700 msec off the persistent_timeout_jump test (21205b8)
|
|
o Check return value of write() in regress.c (c8009d2)
|
|
o Make load-dependent monotonic timer tests off-by-default (2b6fe8b)
|
|
o Add deferred_cb_skew to list of timing-dependent tests (34c8f31)
|
|
o Avoid test -e; older shs don't have one. (f1bd938)
|
|
o Fix renegotiation test to work around openssl 1.0.1 bug (c2f3086)
|
|
o Fix a couple of compile warnings in the unit tests (5a9a014)
|
|
|
|
MISC:
|
|
o Change evutil_weakrand_() to avoid platform random() (e86af4b Nicholas
|
|
Marriott, 3aa4415)
|
|
|
|
INFRASTRUCTURE (Active-later events):
|
|
As a simplification and optimization to Libevent's "deferred callback"
|
|
logic (introduced in 2.0 to avoid callback recursion), Libevent now
|
|
treats all of its deferrable callback types using the same logic it uses
|
|
for active events. Now deferred events no longer cause priority
|
|
inversion, no longer require special code to cancel them, and so on.
|
|
|
|
o Refactor the callback part of an event into its own event_callback
|
|
type (cba59e5)
|
|
o Add "active later" event_callbacks to supersede deferred (745a63d)
|
|
o event_base_assert_ok: check value of event_active_count for
|
|
correctness (fec8bae)
|
|
o Replace deferred_cbs with event_callback-based implementation. (ae2b84b)
|
|
o Replace more deferred_cb names with event_callback (a4079aa)
|
|
o Give event_base_process_active a single exit path (581b5be)
|
|
o Restore our priority-inversion-prevention code with deferreds (c0e425a)
|
|
o Refactor event_persist_closure: raise and extract some common logic
|
|
(bec22b4)
|
|
o Remove the unused bits from EVLIST_ALL (9889a3d)

Changes in version 2.1.1-alpha (4 Apr 2012)
|
|
|
|
Libevent 2.1.1-alpha includes a number of new features and performance
|
|
improvements. The log below tries to organize them by rough area of
|
|
effect. It omits some commits which were pure bugfixes on other commits
|
|
listed below. For more detail, see the git changelogs. For more
|
|
insight, see the "whatsnew-2.1.txt" document included in the Libevent
|
|
2.1.1-alpha distribution.
|
|
|
|
Performance: Core
|
|
o Replace several TAILQ users with LIST. LIST can be a little faster than
|
|
TAILQ for cases where we don't need queue-like behavior. (f9db33d,
|
|
6494772, d313c29, 974d004)
|
|
o Disabled code to optimize the case where we reinsert an existing
|
|
timeout (e47042f, 09cbc3d)
|
|
o Remove a needless base-notify when rescheduling the first timeout (77a96fd)
|
|
o Save a needless comparison when removing/adjusting timeouts (dd5189b)
|
|
o Possible optimization: split event_queue_insert/remove into
|
|
separate functions. needs testing (efc4dc5)
|
|
o Make event_count maintenance branchless at the expense of an
|
|
extra shift. Needs benchmarking (d1cee3b)
|
|
o In the 2.1 branch, let's try out lazy gettimeofday/clock_gettime
|
|
comparison (2a83ecc)
|
|
o Optimization in event_process_active(): ignore maxcb & endtime
|
|
for highest priority events. (a9866aa Alexander Drozdov)
|
|
o Bypass event_add when using event_base_once() for a 0-sec timeout (35c5c95)
|
|
o Remove the eventqueue list and the ev_next pointers. (604569b 066775e)
|
|
|
|
Performance: Evbuffers
|
|
o Roughly 20% speed increase when line-draining a buffer using
|
|
EVBUFFER_EOL_CRLF (5dde0f0 Mina Naguib)
|
|
o Try to squeeze a little more speed out of EVBUFFER_EOL_CRLF (7b9d139)
|
|
o Fix a bug in the improved EOL_CRLF code (d927965)
|
|
o Remove a needless branch in evbuffer_drain() (d19a326)
|
|
|
|
Performance: Linux
|

|
|
sockets (a1c042b)
|
|
o Minimize syscalls during socket creation in listener.c (7e9e289)
|
|
o Use a wrapper function to create the notification
|
|
pipe/socketpair/eventfd (ca76cd9)

|
o Use pipes for telling signals to main thread when possible (a35f396)
|
|
o Save syscalls when constructing listener sockets for evhttp (af6c9d8)
|
|
o Save some syscalls when creating evdns sockets (713e570)
|
|
o Save some syscalls when constructing a socket for a bufferevent (33fca62)
|
|
o Prefer epoll_create1 on Linuxen that have it (bac906c)
|
|
|
|
Performance: Epoll backend
|
|
o Use current event set rather than current pending change when
|
|
deciding whether to no-op a del (04ba27e Mike Smellie)
|
|
o Replace big chain of if/thens in epoll.c with a table lookup (8c83eb6)
|
|
o Clean up error handling in epoll_apply_one_change() a little (2d55a19)
|
|
|
|
Performance: Evport backend
|
|
o evport: use evmap_io to track fdinfo status. Should save time and
|
|
RAM. (4687ce4)
|
|
o evport: Remove a linear search over recent events when
|
|
reactivating them (0f77efe)
|
|

|
|
|
|
Performance: Windows
