17 root 1.287
18 root 1.295 - events on files were not always generated properly with the
19     epoll backend (testcase by Assaf Inbal).
20 root 1.288 - mark event pipe fd as cloexec after a fork (analyzed by Sami Farin).
21 root 1.289 - (ecb) support m68k, m88k and sh (patch by Miod Vallat).
22 root 1.291 - use a reasonable fallback for EV_NSIG instead of erroring out
23     when we can't detect the signal set size.
24 root 1.292 - in the absence of autoconf, do not use the clock syscall
25     on glibc >= 2.17 (avoids the syscall AND -lrt on systems
26     doing clock_gettime in userspace).
27 root 1.293 - ensure extern "C" function pointers are used for externally-visible
28     loop callbacks (not watcher callbacks yet).
29 root 1.294 - (ecb) work around memory barriers and volatile apparently both being
30     broken in visual studio 2008 and later (analysed and patch by Nicolas Noble).
31 root 1.288
32 root 1.287 4.15 Fri Mar 1 12:04:50 CET 2013
33 root 1.271 - destroying a non-default loop would stop the global waitpid
34     watcher (Denis Bilenko).
35 root 1.266 - queueing pending watchers of higher priority from a watcher now invokes
36     them in a timely fashion (reported by Denis Bilenko).
37 root 1.261 - add throw() to all libev functions that cannot throw exceptions, for
38     further code size decrease when compiling for C++.
39     - add throw () to callbacks that must not throw exceptions (allocator,
40     syserr, loop acquire/release, periodic reschedule cbs).
41 root 1.256 - fix event_base_loop return code, add event_get_callback, event_base_new,
42     event_base_get_method calls to improve libevent 1.x emulation and add
43 root 1.273 some libevent 2.x functionality (based on a patch by Jeff Davey).
44 root 1.263 - add more memory fences to fix a bug reported by Jeff Davey. Better
45     be overfenced than underprotected.
46 root 1.256 - ev_run now returns a boolean status (true meaning watchers are
47     still active).
48 root 1.252 - ev_once: undef EV_ERROR in ev_kqueue.c, to avoid clashing with
49     libev's EV_ERROR (reported by 191919).
50 root 1.253 - (ecb) add memory fence support for xlC (Darin McBride).
51     - (ecb) add memory fence support for gcc-mips (Anton Kirilov).
52 root 1.259 - (ecb) add memory fence support for gcc-alpha (Christian Weisgerber).
53 root 1.254 - work around some kernels losing file descriptors by leaking
54     the kqueue descriptor in the child.
55 root 1.282 - work around linux inotify not reporting IN_ATTRIB changes for directories
56     in many cases.
57 root 1.262 - include sys/syscall.h instead of plain syscall.h.
58 root 1.268 - check for io watcher loops in ev_verify, check for the most
59     common reported usage bug in ev_io_start.
60 sf-exg 1.286 - choose socket vs. WSASocket at compiletime using EV_USE_WSASOCKET.
61 root 1.270 - always use WSASend/WSARecv directly on windows, hoping that this
62     works in all cases (unlike read/write/send/recv...).
63 root 1.274 - try to detect signals around a fork faster (test program by
64     Denis Bilenko).
65 root 1.275 - work around recent glibc versions that leak memory in realloc.
66 root 1.276 - rename ev::embed::set to ev::embed::set_embed to avoid clashing
67     the watcher base set (loop) method.
68 root 1.278 - rewrite the async/signal pipe logic to always keep a valid fd, which
69 sf-exg 1.286 simplifies (and hopefully correctifies :) the race checking
70 root 1.278 on fork, at the cost of one extra fd.
71 root 1.282 - add fat, msdos, jffs2, ramfs, ntfs and btrfs to the list of
72     inotify-supporting filesystems.
73 root 1.283 - move orig_CFLAGS assignment to after AC_INIT, as newer autoconf
74     versions ignore it before
75     (https://bugzilla.redhat.com/show_bug.cgi?id=908096).
76 root 1.284 - add some untested android support.
77 root 1.285 - enum expressions must be of type int (reported by Juan Pablo L).
78 root 1.253
79 root 1.250 4.11 Sat Feb 4 19:52:39 CET 2012
80 root 1.248 - INCOMPATIBLE CHANGE: ev_timer_again now clears the pending status, as
81     was documented already, but not implemented in the repeating case.
82 root 1.249 - new compiletime symbols: EV_NO_SMP and EV_NO_THREADS.
83 root 1.234 - fix a race where the workaround against the epoll fork bugs
84     caused signals to not be handled anymore.
85 root 1.229 - correct backend_fudge for most backends, and implement a windows
86     specific workaround to avoid looping because we call both
87     select and Sleep, both with different time resolutions.
88 root 1.230 - document range and guarantees of ev_sleep.
89 root 1.231 - document reasonable ranges for periodics interval and offset.
90     - rename backend_fudge to backend_mintime to avoid future confusion :)
91 root 1.225 - change the default periodic reschedule function to hopefully be more
92 root 1.226 exact and correct even in corner cases or in the far future.
93 root 1.225 - do not rely on -lm anymore: use it when available but use our
94 root 1.230 own floor () if it is missing. This should make it easier to embed,
95     as no external libraries are required.
96 root 1.232 - strategically import macros from libecb and mark rarely-used functions
97 sf-exg 1.239 as cache-cold (saving almost 2k code size on typical amd64 setups).
98 root 1.237 - add Symbols.ev and Symbols.event files, that were missing.
99 root 1.242 - fix backend_mintime value for epoll (was 1/1024, is 1/1000 now).
100 root 1.244 - fix #3 "be smart about timeouts" to not "deadlock" when
101     timeout == now, also improve the section overall.
102     - avoid "AVOIDING FINISHING BEFORE RETURNING" idiom.
103 root 1.245 - support new EV_API_STATIC mode to make all libev symbols
104     static.
105 root 1.251 - supply default CFLAGS of -g -O3 with gcc when original CFLAGS
106     were empty.
107 root 1.225
108 root 1.224 4.04 Wed Feb 16 09:01:51 CET 2011
109     - fix two problems in the native win32 backend, where reuse of fd's
110     with different underlying handles caused handles not to be removed
111     or added to the select set (analyzed and tested by Bert Belder).
112 root 1.221 - do no rely on ceil() in ev_e?poll.c.
113 root 1.222 - backport libev to HP-UX versions before 11 v3.
114 root 1.223 - configure did not detect nanosleep and clock_gettime properly when
115     they are available in the libc (as opposed to -lrt).
116 root 1.221
117 root 1.219 4.03 Tue Jan 11 14:37:25 CET 2011
118 root 1.217 - officially support polling files with all backends.
119 root 1.212 - support files, /dev/zero etc. the same way as select in the epoll
120     backend, by generating events on our own.
121 root 1.217 - ports backend: work around solaris bug 6874410 and many related ones
122     (EINTR, maybe more), with no performance loss (note that the solaris
123     bug report is actually wrong, reality is far more bizarre and broken
124     than that).
125 root 1.209 - define EV_READ/EV_WRITE as macros in event.h, as some programs use
126     #ifdef to test for them.
127 root 1.213 - new (experimental) function: ev_feed_signal.
128     - new (to become default) EVFLAG_NOSIGMASK flag.
129     - new EVBACKEND_MASK symbol.
130 root 1.220 - updated COMMON IDIOMS SECTION.
131 root 1.209
132 root 1.207 4.01 Fri Nov 5 21:51:29 CET 2010
133 root 1.205 - automake fucked it up, apparently, --add-missing -f is not quite enough
134 root 1.206 to make it update its files, so 4.00 didn't install ev++.h and
135     event.h on make install. grrr.
136     - ev_loop(count|depth) didn't return anything (Robin Haberkorn).
137 root 1.203 - change EV_UNDEF to 0xffffffff to silence some overzealous compilers.
138 root 1.204 - use "(libev) " prefix for all libev error messages now.
139 root 1.203
140 root 1.202 4.00 Mon Oct 25 12:32:12 CEST 2010
141 root 1.171 - "PORTING FROM LIBEV 3.X TO 4.X" (in ev.pod) is recommended reading.
142 root 1.161 - ev_embed_stop did not correctly stop the watcher (very good
143     testcase by Vladimir Timofeev).
144 sf-exg 1.191 - ev_run will now always update the current loop time - it erroneously
145 root 1.187 didn't when idle watchers were active, causing timers not to fire.
146 root 1.179 - fix a bug where a timeout of zero caused the timer not to fire
147     in the libevent emulation (testcase by Péter Szabó).
148 root 1.164 - applied win32 fixes by Michael Lenaghan (also James Mansion).
149 root 1.166 - replace EV_MINIMAL by EV_FEATURES.
150 root 1.178 - prefer EPOLL_CTL_ADD over EPOLL_CTL_MOD in some more cases, as it
151     seems the former is *much* faster than the latter.
152 root 1.197 - linux kernel version detection (for inotify bug workarounds)
153     did not work properly.
154 root 1.185 - reduce the number of spurious wake-ups with the ports backend.
155 root 1.158 - remove dependency on sys/queue.h on freebsd (patch by Vanilla Hsu).
156 root 1.186 - do async init within ev_async_start, not ev_async_set, which avoids
157     an API quirk where the set function must be called in the C++ API
158     even when there is nothing to set.
159 root 1.174 - add (undocumented) EV_ENABLE when adding events with kqueue,
160 root 1.175 this might help with OS X, which seems to need it despite documenting
161     not to need it (helpfully pointed out by Tilghman Lesher).
162 root 1.176 - do not use poll by default on freebsd, it's broken (what isn't
163     on freebsd...).
164 root 1.195 - allow to embed epoll on kernels >= 2.6.32.
165 root 1.159 - configure now prepends -O3, not appends it, so one can still
166     override it.
167 root 1.190 - ev.pod: greatly expanded the portability section, added a porting
168     section, a description of watcher states and made lots of minor fixes.
169 root 1.160 - disable poll backend on AIX, the poll header spams the namespace
170     and it's not worth working around dead platforms (reported
171     and analyzed by Aivars Kalvans).
172 root 1.162 - improve header file compatibility of the standalone eventfd code
173     in an obscure case.
174 root 1.163 - implement EV_AVOID_STDIO option.
175     - do not use sscanf to parse linux version number (smaller, faster,
176     no sscanf dependency).
177 root 1.164 - new EV_CHILD_ENABLE and EV_SIGNAL_ENABLE configurable settings.
178 sf-exg 1.172 - update libev.m4 HAVE_CLOCK_SYSCALL test for newer glibcs.
179 root 1.165 - add section on accept() problems to the manpage.
180 root 1.168 - rename EV_TIMEOUT to EV_TIMER.
181 root 1.190 - rename ev_loop_count/depth/verify/loop/unloop.
182 root 1.197 - remove ev_default_destroy and ev_default_fork.
183 root 1.168 - switch to two-digit minor version.
184 root 1.180 - work around an apparent gentoo compiler bug.
185 root 1.181 - define _DARWIN_UNLIMITED_SELECT. just so.
186 root 1.188 - use enum instead of #define for most constants.
187     - improve compatibility to older C++ compilers.
188 root 1.193 - (experimental) ev_run/ev_default_loop/ev_break/ev_loop_new have now
189     default arguments when compiled as C++.
190 root 1.196 - enable automake dependency tracking.
191 root 1.197 - ev_loop_new no longer leaks memory when loop creation failed.
192 root 1.198 - new ev_cleanup watcher type.
193 root 1.157
194 root 1.156 3.9 Thu Dec 31 07:59:59 CET 2009
195 root 1.155 - signalfd is no longer used by default and has to be requested
196     explicitly - this means that easy to catch bugs become hard to
197     catch race conditions, but the users have spoken.
198     - point out the unspecified signal mask in the documentation, and
199     that this is a race condition regardless of EV_SIGNALFD.
200 root 1.142 - backport inotify code to C89.
201 root 1.148 - inotify file descriptors could leak into child processes.
202 sf-exg 1.241 - ev_stat watchers could keep an erroneous extra ref on the loop,
203 root 1.151 preventing exit when unregistering all watchers (testcases
204 root 1.150 provided by ry@tinyclouds.org).
205 root 1.143 - implement EV_WIN32_HANDLE_TO_FD and EV_WIN32_CLOSE_FD configuration
206 root 1.145 symbols to make it easier for apps to do their own fd management.
207 root 1.144 - support EV_IDLE_ENABLE being disabled in ev++.h
208     (patch by Didier Spezia).
209 root 1.147 - take advantage of inotify_init1, if available, to set cloexec/nonblock
210     on fd creation, to avoid races.
211 root 1.150 - the signal handling pipe wasn't always initialised under windows
212     (analysed by lekma).
213 root 1.146 - changed minimum glibc requirement from glibc 2.9 to 2.7, for
214     signalfd.
215 root 1.152 - add missing string.h include (Denis F. Latypoff).
216 root 1.153 - only replace ev_stat.prev when we detect an actual difference,
217     so prev is (almost) always different to attr. this might
218 sf-exg 1.191 have caused the problems with 04_stat.t.
219 root 1.154 - add ev::timer->remaining () method to C++ API.
220 root 1.142
221 root 1.141 3.8 Sun Aug 9 14:30:45 CEST 2009
222 root 1.133 - incompatible change: do not necessarily reset signal handler
223     to SIG_DFL when a sighandler is stopped.
224 root 1.135 - ev_default_destroy did not properly free or zero some members,
225 sf-exg 1.191 potentially causing crashes and memory corruption on repeated
226 root 1.134 ev_default_destroy/ev_default_loop calls.
227 root 1.133 - take advantage of signalfd on GNU/Linux systems.
228     - document that the signal mask might be in an unspecified
229     state when using libev's signal handling.
230 root 1.136 - take advantage of some GNU/Linux calls to set cloexec/nonblock
231     on fd creation, to avoid race conditions.
232 root 1.132
233 root 1.131 3.7 Fri Jul 17 16:36:32 CEST 2009
234 root 1.128 - ev_unloop and ev_loop wrongly used a global variable to exit loops,
235     instead of using a per-loop variable (bug caught by accident...).
236     - the ev_set_io_collect_interval interpretation has changed.
237     - add new functionality: ev_set_userdata, ev_userdata,
238 root 1.126 ev_set_invoke_pending_cb, ev_set_loop_release_cb,
239 root 1.132 ev_invoke_pending, ev_pending_count, together with a long example
240     about thread locking.
241 root 1.128 - add ev_timer_remaining (as requested by Denis F. Latypoff).
242     - add ev_loop_depth.
243 root 1.124 - calling ev_unloop in fork/prepare watchers will no longer poll
244     for new events.
245 root 1.115 - Denis F. Latypoff corrected many typos in example code snippets.
246     - honor autoconf detection of EV_USE_CLOCK_SYSCALL, also double-
247     check that the syscall number is available before trying to
248     use it (reported by ry@tinyclouds).
249 root 1.117 - use GetSystemTimeAsFileTime instead of _timeb on windows, for
250 root 1.116 slightly higher accuracy.
251 root 1.122 - properly declare ev_loop_verify and ev_now_update even when
252     !EV_MULTIPLICITY.
253 root 1.121 - do not compile in any priority code when EV_MAXPRI == EV_MINPRI.
254 root 1.123 - support EV_MINIMAL==2 for a reduced API.
255 root 1.125 - actually 0-initialise struct sigaction when installing signals.
256 root 1.127 - add section on hibernate and stopped processes to ev_timer docs.
257 root 1.115
258 root 1.113 3.6 Tue Apr 28 02:49:30 CEST 2009
259 root 1.107 - multiple timers becoming ready within an event loop iteration
260     will be invoked in the "correct" order now.
261 root 1.105 - do not leave the event loop early just because we have no active
262     watchers, fixing a problem when embedding a kqueue loop
263     that has active kernel events but no registered watchers
264     (reported by blacksand blacksand).
265 root 1.102 - correctly zero the idx values for arrays, so destroying and
266     reinitialising the default loop actually works (patch by
267     Malek Hadj-Ali).
268 root 1.108 - implement ev_suspend and ev_resume.
269 root 1.106 - new EV_CUSTOM revents flag for use by applications.
270 sf-exg 1.241 - add documentation section about priorities.
271 sf-exg 1.286 - add a glossary to the documentation.
272 root 1.111 - extend the ev_fork description slightly.
273 root 1.112 - optimize a jump out of call_pending.
274 root 1.102
275 root 1.101 3.53 Sun Feb 15 02:38:20 CET 2009
276     - fix a bug in event pipe creation on win32 that would cause a
277     failed assertion on event loop creation (patch by Malek Hadj-Ali).
278 root 1.100 - probe for CLOCK_REALTIME support at runtime as well and fall
279     back to gettimeofday if there is an error, to support older
280     operating systems with newer header files/libraries.
281     - prefer gettimeofday over clock_gettime with USE_CLOCK_SYSCALL
282     (default most everywhere), otherwise not.
283    
284 root 1.99 3.52 Wed Jan 7 21:43:02 CET 2009
285 root 1.97 - fix compilation of select backend in fd_set mode when NFDBITS is
286     missing (to get it to compile on QNX, reported by Rodrigo Campos).
287     - better select-nfds handling when select backend is in fd_set mode.
288     - diagnose fd_set overruns when select backend is in fd_set mode.
289     - due to a thinko, instead of disabling everything but
290     select on the borked OS X platform, everything but select was
291     allowed (reported by Emanuele Giaquinta).
292 root 1.95 - actually verify that local and remote port are matching in
293     libev's socketpair emulation, which makes denial-of-service
294     attacks harder (but not impossible - it's windows). Make sure
295 root 1.96 it even works under vista, which thinks that getpeer/sockname
296     should return fantasy port numbers.
297 root 1.100 - include "libev" in all assertion messages for potentially
298 root 1.97 clearer diagnostics.
299 root 1.98 - event_get_version (libevent compatibility) returned
300     a useless string instead of the expected version string
301     (patch by W.C.A. Wijngaards).
302 root 1.95
303 root 1.94 3.51 Wed Dec 24 23:00:11 CET 2008
304 root 1.91 - fix a bug where an inotify watcher was added twice, causing
305 root 1.92 freezes on hash collisions (reported and analysed by Graham Leggett).
306 root 1.87 - new config symbol, EV_USE_CLOCK_SYSCALL, to make libev use
307     a direct syscall - slower, but no dependency on librt et al.
308 root 1.88 - assume negative return values != -1 signals success of port_getn
309     (http://cvs.epicsol.org/cgi/viewcvs.cgi/epic5/source/newio.c?rev=1.52)
310     (no known failure reports, but it doesn't hurt).
311 root 1.93 - fork detection in ev_embed now stops and restarts the watcher
312     automatically.
313 root 1.89 - EXPERIMENTAL: default the method to operator () in ev++.h,
314     to make it nicer to use functors (requested by Benedek László).
315     - fixed const object callbacks in ev++.h.
316 root 1.90 - replaced loop_ref argument of watcher.set (loop) by a direct
317     ev_loop * in ev++.h, to avoid clashes with functor patch.
318 root 1.91 - do not try to watch the empty string via inotify.
319 root 1.92 - inotify watchers could be leaked under certain circumstances.
320     - OS X 10.5 is actually even more broken than earlier versions,
321     so fall back to select on that piece of garbage.
322 root 1.93 - fixed some weirdness in the ev_embed documentation.
323 root 1.87
324 root 1.86 3.49 Wed Nov 19 11:26:53 CET 2008
325 root 1.83 - ev_stat watchers will now use inotify as a mere hint on
326     kernels <2.6.25, or if the filesystem is not in the
327     "known to be good" list.
328 root 1.84 - better mingw32 compatibility (it's not as borked as native win32)
329     (analysed by Roger Pack).
330 root 1.85 - include stdio.h in the example program, as too many people are
331     confused by the weird C language otherwise. I guess the next thing
332     I get told is that the "..." ellipses in the examples don't compile
333     with their C compiler.
334 root 1.83
335 root 1.80 3.48 Thu Oct 30 09:02:37 CET 2008
336 root 1.71 - further optimise away the EPOLL_CTL_ADD/MOD combo in the epoll
337     backend by assuming the kernel event mask hasn't changed if
338     ADD fails with EEXIST.
339 root 1.75 - work around spurious event notification bugs in epoll by using
340 root 1.77 a 32-bit generation counter. recreate kernel state if we receive
341 root 1.78 spurious notifications or unwanted events. this is very costly,
342     but I didn't come up with this horrible design.
343 root 1.71 - use memset to initialise most arrays now and do away with the
344     init functions.
345 root 1.72 - expand time-out strategies into a "Be smart about timeouts" section.
346     - drop the "struct" from all ev_watcher declarations in the
347 root 1.73 documentation and did other clarifications (yeah, it was a mistake
348     to have a struct AND a function called ev_loop).
349 root 1.74 - fix a bug where ev_default would not initialise the default
350     loop again after it was destroyed with ev_default_destroy.
351 root 1.79 - rename syserr to ev_syserr to avoid name clashes when embedding,
352     do similar changes for event.c.
353 root 1.71
354 root 1.69 3.45 Tue Oct 21 21:59:26 CEST 2008
355 root 1.67 - disable inotify usage on linux <2.6.25, as it is broken
356     (reported by Yoann Vandoorselaere).
357 sf-exg 1.191 - ev_stat erroneously would try to add inotify watchers
358 root 1.68 even when inotify wasn't available (this should only
359 root 1.67 have a performance impact).
360 root 1.65 - ev_once now passes both timeout and io to the callback if both
361     occur concurrently, instead of giving timeouts precedence.
362 root 1.66 - disable EV_USE_INOTIFY when sys/inotify.h is too old.
363 root 1.65
364 root 1.62 3.44 Mon Sep 29 05:18:39 CEST 2008
365     - embed watchers now automatically invoke ev_loop_fork on the
366     embedded loop when the parent loop forks.
367 root 1.58 - new function: ev_now_update (loop).
368 root 1.57 - verify_watcher was not marked static.
369 root 1.59 - improve the "associating..." manpage section.
370 root 1.60 - documentation tweaks here and there.
371 root 1.57
372 root 1.56 3.43 Sun Jul 6 05:34:41 CEST 2008
373 root 1.54 - include more include files on windows to get struct _stati64
374 root 1.56 (reported by Chris Hulbert, but doesn't quite fix his issue).
375 root 1.53 - add missing #include <io.h> in ev.c on windows (reported by
376     Matt Tolton).
377    
378 root 1.52 3.42 Tue Jun 17 12:12:07 CEST 2008
379 root 1.50 - work around yet another windows bug: FD_SET actually adds fd's
380     multiple times to the fd_*SET*, despite official MSN docs claiming
381 root 1.51 otherwise. Reported and well-analysed by Matt Tolton.
382     - define NFDBITS to 0 when EV_SELECT_IS_WINSOCKET to make it compile
383 root 1.48 (reported any analysed by Chris Hulbert).
384 root 1.49 - fix a bug in ev_ebadf (this function is only used to catch
385     programming errors in the libev user). reported by Matt Tolton.
386     - fix a bug in fd_intern on win32 (could lead to compile errors
387     under some circumstances, but would work correctly if it compiles).
388     reported by Matt Tolton.
389 root 1.50 - (try to) work around missing lstat on windows.
390 root 1.45 - pass in the write fd set as except fd set under windows. windows
391 root 1.46 is so uncontrollably lame that it requires this. this means that
392     switching off oobinline is not supported (but tcp/ip doesn't
393     have oob, so that would be stupid anyways.
394 root 1.47 - use posix module symbol to auto-detect monotonic clock presence
395     and some other default values.
396 root 1.45
397 root 1.44 3.41 Fri May 23 18:42:54 CEST 2008
398 root 1.46 - work around an obscure bug in winsocket select: if you
399 root 1.40 provide only empty fd sets then select returns WSAEINVAL. how sucky.
400 root 1.41 - improve timer scheduling stability and reduce use of time_epsilon.
401 root 1.36 - use 1-based 2-heap for EV_MINIMAL, simplifies code, reduces
402     codesize and makes for better cache-efficiency.
403     - use 3-based 4-heap for !EV_MINIMAL. this makes better use
404     of cpu cache lines and gives better growth behaviour than
405     2-based heaps.
406 root 1.38 - cache timestamp within heap for !EV_MINIMAL, to avoid random
407     memory accesses.
408     - document/add EV_USE_4HEAP and EV_HEAP_CACHE_AT.
409 root 1.33 - fix a potential aliasing issue in ev_timer_again.
410 root 1.35 - add/document ev_periodic_at, retract direct access to ->at.
411     - improve ev_stat docs.
412     - add portability requirements section.
413 root 1.39 - fix manpage headers etc.
414 root 1.40 - normalise WSA error codes to lower range on windows.
415 root 1.43 - add consistency check code that can be called automatically
416     or on demand to check for internal structures (ev_loop_verify).
417 root 1.31
418 root 1.30 3.31 Wed Apr 16 20:45:04 CEST 2008
419     - added last minute fix for ev_poll.c by Brandon Black.
420 root 1.29
421 root 1.28 3.3 Wed Apr 16 19:04:10 CEST 2008
422 root 1.23 - event_base_loopexit should return 0 on success
423     (W.C.A. Wijngaards).
424 root 1.20 - added linux eventfd support.
425     - try to autodetect epoll and inotify support
426     by libc header version if not using autoconf.
427 root 1.21 - new symbols: EV_DEFAULT_UC and EV_DEFAULT_UC_.
428     - declare functions defined in ev.h as inline if
429     C99 or gcc are available.
430     - enable inlining with gcc versions 2 and 3.
431 root 1.25 - work around broken poll implementations potentially
432     not clearing revents field in ev_poll (Brandon Black)
433     (no such systems are known at this time).
434 root 1.23 - work around a bug in realloc on openbsd and darwin,
435 sf-exg 1.191 also makes the erroneous valgrind complaints
436 root 1.23 go away (noted by various people).
437 root 1.26 - fix ev_async_pending, add c++ wrapper for ev_async
438 sf-exg 1.191 (based on patch sent by Johannes Deisenhofer).
439 root 1.26 - add sensible set method to ev::embed.
440 root 1.27 - made integer constants type int in ev.h.
441 root 1.20
442 root 1.19 3.2 Wed Apr 2 17:11:19 CEST 2008
443 root 1.15 - fix a 64 bit overflow issue in the select backend,
444     by using fd_mask instead of int for the mask.
445 root 1.16 - rename internal sighandler to avoid clash with very old perls.
446 root 1.18 - entering ev_loop will not clear the ONESHOT or NONBLOCKING
447     flags of any outer loops anymore.
448 root 1.17 - add ev_async_pending.
449 root 1.15
450 root 1.14 3.1 Thu Mar 13 13:45:22 CET 2008

457 root 1.6 - API/ABI bump to version 3.0.
458 root 1.4 - ev++.h includes "ev.h" by default now, not <ev.h>.
459     - slightly improved documentation.
460 root 1.5 - speed up signal detection after a fork.
461 root 1.6 - only optionally return trace status changed in ev_child
462     watchers.

468     - remove event_compat.h from the libev tarball.
469     - change how include files are found.
