Revision history for libev, a high-performance and full-featured event loop.
3.4
- work around an (undocumented) bug in winsocket select: if you
provide only empty fd sets then select returns WSAEINVAL. how sucky.
- improve timer scheduling stability and reduce use of time_epsilon.
- use 1-based 2-heap for EV_MINIMAL, simplifies code, reduces
codesize and makes for better cache-efficiency.
- use 3-based 4-heap for !EV_MINIMAL. this makes better use
of cpu cache lines and gives better growth behaviour than
2-based heaps.
- cache timestamp within heap for !EV_MINIMAL, to avoid random
memory accesses.
- document/add EV_USE_4HEAP and EV_HEAP_CACHE_AT.
- fix a potential aliasing issue in ev_timer_again.
- add/document ev_periodic_at, retract direct access to ->at.
- improve ev_stat docs.
- add portability requirements section.
- fix manpage headers etc.
- normalise WSA error codes to lower range on windows.
3.31 Wed Apr 16 20:45:04 CEST 2008
- added last minute fix for ev_poll.c by Brandon Black.
3.3 Wed Apr 16 19:04:10 CEST 2008
- event_base_loopexit should return 0 on success
(W.C.A. Wijngaards).
- added linux eventfd support.
- try to autodetect epoll and inotify support
by libc header version if not using autoconf.
- new symbols: EV_DEFAULT_UC and EV_DEFAULT_UC_.
- declare functions defined in ev.h as inline if
C99 or gcc are available.
- enable inlining with gcc versions 2 and 3.
- work around broken poll implementations potentially
not clearing revents field in ev_poll (Brandon Black)
(no such systems are known at this time).
- work around a bug in realloc on openbsd and darwin,
also makes the errornous valgrind complaints
go away (noted by various people).
- fix ev_async_pending, add c++ wrapper for ev_async
(based on patch sent by Johannes Deisenhofer.
- add sensible set method to ev::embed.
- made integer constants type int in ev.h.
3.2 Wed Apr 2 17:11:19 CEST 2008
- fix a 64 bit overflow issue in the select backend,
by using fd_mask instead of int for the mask.
- rename internal sighandler to avoid clash with very old perls.
- entering ev_loop will not clear the ONESHOT or NONBLOCKING
flags of any outer loops anymore.
- add ev_async_pending.
3.1 Thu Mar 13 13:45:22 CET 2008
- implement ev_async watchers.
- only initialise signal pipe on demand.
- make use of sig_atomic_t configurable.
- improved documentation.
3.0 Mon Jan 28 13:14:47 CET 2008
- API/ABI bump to version 3.0.
- ev++.h includes "ev.h" by default now, not <ev.h>.
- slightly improved documentation.
- speed up signal detection after a fork.
- only optionally return trace status changed in ev_child
watchers.
- experimental (and undocumented) loop wrappers for ev++.h.
2.01 Tue Dec 25 08:04:41 CET 2007
- separate Changes file.
- fix ev_path_set => ev_stat_set typo.
- remove event_compat.h from the libev tarball.
- change how include files are found.
- doc updates.
- update licenses, explicitly allow for GPL relicensing.
2.0 Sat Dec 22 17:47:03 CET 2007
- new ev_sleep, ev_set_(io|timeout)_collect_interval.
- removed epoll from embeddable fd set.
- fix embed watchers.
- renamed ev_embed.loop to other.
- added exported Symbol tables.
- undefine member wrapper macros at the end of ev.c.
- respect EV_H in ev++.h.
1.86 Tue Dec 18 02:36:57 CET 2007
- fix memleak on loop destroy (not relevant for perl).
1.85 Fri Dec 14 20:32:40 CET 2007
- fix some aliasing issues w.r.t. timers and periodics
(not relevant for perl).
(for historic versions refer to EV/Changes, found in the Perl interface)
0.1 Wed Oct 31 21:31:48 CET 2007
- original version; hacked together in <24h.
