Revision history for libev, a high-performance and full-featured event loop.
-TODO: ev_loop_wakeup
-
-4.10
+ - ANDROID => __ANDROID__ (reported by enh@google.com).
+ - disable epoll_create1 on android because it has broken header files
+ and google is unwilling to fix them (reported by enh@google.com).
+
+4.24 Wed Dec 28 05:19:55 CET 2016
+ - bump version to 4.24, as the release tarball inexplicably
+ didn't have the right version in ev.h, even though the cvs-tagged
+ version did have the right one (reported by Ales Teska).
+
+4.23 Wed Nov 16 18:23:41 CET 2016
+ - move some declarations at the beginning to help certain retarded
+ microsoft compilers, even though their documentation claims
+ otherwise (reported by Ruslan Osmanov).
+
+4.22 Sun Dec 20 22:11:50 CET 2015
+ - when epoll detects unremovable fds in the fd set, rebuild
+ only the epoll descriptor, not the signal pipe, to avoid
+ SIGPIPE in ev_async_send. This doesn't solve it on fork,
+ so document what needs to be done in ev_loop_fork
+ (analyzed by Benjamin Mahler).
+ - remove superfluous sys/timeb.h include on win32
+ (analyzed by Jason Madden).
+ - updated libecb.
+
+4.20 Sat Jun 20 13:01:43 CEST 2015
+ - prefer noexcept over throw () with C++ 11.
+ - update ecb.h due to incompatibilities with c11.
+ - fix a potential aliasing issue when reading and writing
+ watcher callbacks.
+
+4.19 Thu Sep 25 08:18:25 CEST 2014
+ - ev.h wasn't valid C++ anymore, which tripped compilers other than
+ clang, msvc or gcc (analyzed by Raphael 'kena' Poss). Unfortunately,
+ C++ doesn't support typedefs for function pointers fully, so the affected
+ declarations have to spell out the types each time.
+ - when not using autoconf, tighten the check for clock_gettime and related
+ functionality.
+
+4.18 Fri Sep 5 17:55:26 CEST 2014
+ - events on files were not always generated properly with the
+ epoll backend (testcase by Assaf Inbal).
+ - mark event pipe fd as cloexec after a fork (analyzed by Sami Farin).
+ - (ecb) support m68k, m88k and sh (patch by Miod Vallat).
+ - use a reasonable fallback for EV_NSIG instead of erroring out
+ when we can't detect the signal set size.
+ - in the absence of autoconf, do not use the clock syscall
+ on glibc >= 2.17 (avoids the syscall AND -lrt on systems
+ doing clock_gettime in userspace).
+ - ensure extern "C" function pointers are used for externally-visible
+ loop callbacks (not watcher callbacks yet).
+ - (ecb) work around memory barriers and volatile apparently both being
+ broken in visual studio 2008 and later (analysed and patch by Nicolas Noble).
+
+4.15 Fri Mar 1 12:04:50 CET 2013
+ - destroying a non-default loop would stop the global waitpid
+ watcher (Denis Bilenko).
+ - queueing pending watchers of higher priority from a watcher now invokes
+ them in a timely fashion (reported by Denis Bilenko).
+ - add throw() to all libev functions that cannot throw exceptions, for
+ further code size decrease when compiling for C++.
+ - add throw () to callbacks that must not throw exceptions (allocator,
+ syserr, loop acquire/release, periodic reschedule cbs).
+ - fix event_base_loop return code, add event_get_callback, event_base_new,
+ event_base_get_method calls to improve libevent 1.x emulation and add
+ some libevent 2.x functionality (based on a patch by Jeff Davey).
+ - add more memory fences to fix a bug reported by Jeff Davey. Better
+ be overfenced than underprotected.
+ - ev_run now returns a boolean status (true meaning watchers are
+ still active).
+ - ev_once: undef EV_ERROR in ev_kqueue.c, to avoid clashing with
+ libev's EV_ERROR (reported by 191919).
+ - (ecb) add memory fence support for xlC (Darin McBride).
+ - (ecb) add memory fence support for gcc-mips (Anton Kirilov).
+ - (ecb) add memory fence support for gcc-alpha (Christian Weisgerber).
+ - work around some kernels losing file descriptors by leaking
+ the kqueue descriptor in the child.
+ - work around linux inotify not reporting IN_ATTRIB changes for directories
+ in many cases.
+ - include sys/syscall.h instead of plain syscall.h.
+ - check for io watcher loops in ev_verify, check for the most
+ common reported usage bug in ev_io_start.
+ - choose socket vs. WSASocket at compiletime using EV_USE_WSASOCKET.
+ - always use WSASend/WSARecv directly on windows, hoping that this
+ works in all cases (unlike read/write/send/recv...).
+ - try to detect signals around a fork faster (test program by
+ Denis Bilenko).
+ - work around recent glibc versions that leak memory in realloc.
+ - rename ev::embed::set to ev::embed::set_embed to avoid clashing
+ the watcher base set (loop) method.
+ - rewrite the async/signal pipe logic to always keep a valid fd, which
+ simplifies (and hopefully correctifies :) the race checking
+ on fork, at the cost of one extra fd.
+ - add fat, msdos, jffs2, ramfs, ntfs and btrfs to the list of
+ inotify-supporting filesystems.
+ - move orig_CFLAGS assignment to after AC_INIT, as newer autoconf
+ versions ignore it before
+ (https://bugzilla.redhat.com/show_bug.cgi?id=908096).
+ - add some untested android support.
+ - enum expressions must be of type int (reported by Juan Pablo L).
+
+4.11 Sat Feb 4 19:52:39 CET 2012
+ - INCOMPATIBLE CHANGE: ev_timer_again now clears the pending status, as
+ was documented already, but not implemented in the repeating case.
+ - new compiletime symbols: EV_NO_SMP and EV_NO_THREADS.
+ - fix a race where the workaround against the epoll fork bugs
+ caused signals to not be handled anymore.
- correct backend_fudge for most backends, and implement a windows
specific workaround to avoid looping because we call both
select and Sleep, both with different time resolutions.
own floor () if it is missing. This should make it easier to embed,
as no external libraries are required.
- strategically import macros from libecb and mark rarely-used functions
- as cache-chold (saving almost 2k code size on typical amd64 setups).
+ as cache-cold (saving almost 2k code size on typical amd64 setups).
+ - add Symbols.ev and Symbols.event files, that were missing.
+ - fix backend_mintime value for epoll (was 1/1024, is 1/1000 now).
+ - fix #3 "be smart about timeouts" to not "deadlock" when
+ timeout == now, also improve the section overall.
+ - avoid "AVOIDING FINISHING BEFORE RETURNING" idiom.
+ - support new EV_API_STATIC mode to make all libev symbols
+ static.
+ - supply default CFLAGS of -g -O3 with gcc when original CFLAGS
+ were empty.
4.04 Wed Feb 16 09:01:51 CET 2011
- fix two problems in the native win32 backend, where reuse of fd's
that this is a race condition regardless of EV_SIGNALFD.
- backport inotify code to C89.
- inotify file descriptors could leak into child processes.
- - ev_stat watchers could keep an errornous extra ref on the loop,
+ - ev_stat watchers could keep an erroneous extra ref on the loop,
preventing exit when unregistering all watchers (testcases
provided by ry@tinyclouds.org).
- implement EV_WIN32_HANDLE_TO_FD and EV_WIN32_CLOSE_FD configuration
Malek Hadj-Ali).
- implement ev_suspend and ev_resume.
- new EV_CUSTOM revents flag for use by applications.
- - add documentation section about priorites.
- - add a glossary to the dcoumentation.
+ - add documentation section about priorities.
+ - add a glossary to the documentation.
- extend the ev_fork description slightly.
- optimize a jump out of call_pending.
