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

369 root 1.57
370 root 1.56 3.43 Sun Jul 6 05:34:41 CEST 2008
371 root 1.54 - include more include files on windows to get struct _stati64
372 root 1.56 (reported by Chris Hulbert, but doesn't quite fix his issue).
373 root 1.53 - add missing #include <io.h> in ev.c on windows (reported by
374     Matt Tolton).
375    
376 root 1.52 3.42 Tue Jun 17 12:12:07 CEST 2008
377 root 1.50 - work around yet another windows bug: FD_SET actually adds fd's
378     multiple times to the fd_*SET*, despite official MSN docs claiming
379 root 1.51 otherwise. Reported and well-analysed by Matt Tolton.
380     - define NFDBITS to 0 when EV_SELECT_IS_WINSOCKET to make it compile
381 root 1.48 (reported any analysed by Chris Hulbert).
382 root 1.49 - fix a bug in ev_ebadf (this function is only used to catch
383     programming errors in the libev user). reported by Matt Tolton.
384     - fix a bug in fd_intern on win32 (could lead to compile errors
385     under some circumstances, but would work correctly if it compiles).
386     reported by Matt Tolton.
387 root 1.50 - (try to) work around missing lstat on windows.
388 root 1.45 - pass in the write fd set as except fd set under windows. windows
389 root 1.46 is so uncontrollably lame that it requires this. this means that
390     switching off oobinline is not supported (but tcp/ip doesn't
391     have oob, so that would be stupid anyways.
392 root 1.47 - use posix module symbol to auto-detect monotonic clock presence
393     and some other default values.
394 root 1.45
395 root 1.44 3.41 Fri May 23 18:42:54 CEST 2008
396 root 1.46 - work around an obscure bug in winsocket select: if you
397 root 1.40 provide only empty fd sets then select returns WSAEINVAL. how sucky.
398 root 1.41 - improve timer scheduling stability and reduce use of time_epsilon.
399 root 1.36 - use 1-based 2-heap for EV_MINIMAL, simplifies code, reduces
400     codesize and makes for better cache-efficiency.
401     - use 3-based 4-heap for !EV_MINIMAL. this makes better use
402     of cpu cache lines and gives better growth behaviour than
403     2-based heaps.
404 root 1.38 - cache timestamp within heap for !EV_MINIMAL, to avoid random
405     memory accesses.
406     - document/add EV_USE_4HEAP and EV_HEAP_CACHE_AT.
407 root 1.33 - fix a potential aliasing issue in ev_timer_again.
408 root 1.35 - add/document ev_periodic_at, retract direct access to ->at.
409     - improve ev_stat docs.
410     - add portability requirements section.
411 root 1.39 - fix manpage headers etc.
412 root 1.40 - normalise WSA error codes to lower range on windows.
413 root 1.43 - add consistency check code that can be called automatically
414     or on demand to check for internal structures (ev_loop_verify).
415 root 1.31
416 root 1.30 3.31 Wed Apr 16 20:45:04 CEST 2008
417     - added last minute fix for ev_poll.c by Brandon Black.
418 root 1.29
419 root 1.28 3.3 Wed Apr 16 19:04:10 CEST 2008
420 root 1.23 - event_base_loopexit should return 0 on success
421     (W.C.A. Wijngaards).
422 root 1.20 - added linux eventfd support.
423     - try to autodetect epoll and inotify support
424     by libc header version if not using autoconf.
425 root 1.21 - new symbols: EV_DEFAULT_UC and EV_DEFAULT_UC_.
426     - declare functions defined in ev.h as inline if
427     C99 or gcc are available.
428     - enable inlining with gcc versions 2 and 3.
429 root 1.25 - work around broken poll implementations potentially
430     not clearing revents field in ev_poll (Brandon Black)
431     (no such systems are known at this time).
432 root 1.23 - work around a bug in realloc on openbsd and darwin,
433 sf-exg 1.191 also makes the erroneous valgrind complaints
434 root 1.23 go away (noted by various people).
435 root 1.26 - fix ev_async_pending, add c++ wrapper for ev_async
436 sf-exg 1.191 (based on patch sent by Johannes Deisenhofer).
437 root 1.26 - add sensible set method to ev::embed.
438 root 1.27 - made integer constants type int in ev.h.
439 root 1.20
440 root 1.19 3.2 Wed Apr 2 17:11:19 CEST 2008
441 root 1.15 - fix a 64 bit overflow issue in the select backend,
442     by using fd_mask instead of int for the mask.
443 root 1.16 - rename internal sighandler to avoid clash with very old perls.
444 root 1.18 - entering ev_loop will not clear the ONESHOT or NONBLOCKING
445     flags of any outer loops anymore.
446 root 1.17 - add ev_async_pending.
447 root 1.15
448 root 1.14 3.1 Thu Mar 13 13:45:22 CET 2008
