# User Rev Content
1 root 1.14 Revision history for libev, a high-performance and full-featured event loop.
2 root 1.1
3 root 1.313 4.24 Wed Dec 28 05:19:55 CET 2016
4     - bump version to 4.24, as the release tarball inexplicably
5     didn't have the right version in ev.h, even though the cvs-tagged
6     version did have the right one (reported by Ales Teska).
7    
8 root 1.312 4.23 Wed Nov 16 18:23:41 CET 2016
9 root 1.311 - move some declarations at the beginning to help certain retarded
10     microsoft compilers, even though their documentation claims
11     otherwise (reported by Ruslan Osmanov).
12    
13 root 1.310 4.22 Sun Dec 20 22:11:50 CET 2015
14 root 1.308 - when epoll detects unremovable fds in the fd set, rebuild
15     only the epoll descriptor, not the signal pipe, to avoid
16     SIGPIPE in ev_async_send. This doesn't solve it on fork,
17     so document what needs to be done in ev_loop_fork
18     (analyzed by Benjamin Mahler).
19     - remove superfluous sys/timeb.h include on win32
20     (analyzed by Jason Madden).
21 root 1.309 - updated libecb.
22 root 1.308
23 root 1.307 4.20 Sat Jun 20 13:01:43 CEST 2015
24 root 1.302 - prefer noexcept over throw () with C++ 11.
25 root 1.303 - update ecb.h due to incompatibilities with c11.
26 root 1.305 - fix a potential aliasing issue when reading and writing
27 root 1.304 watcher callbacks.
28 root 1.301
29 root 1.300 4.19 Thu Sep 25 08:18:25 CEST 2014
30 root 1.298 - ev.h wasn't valid C++ anymore, which tripped compilers other than
31 root 1.299 clang, msvc or gcc (analyzed by Raphael 'kena' Poss). Unfortunately,
32     C++ doesn't support typedefs for function pointers fully, so the affected
33     declarations have to spell out the types each time.
34 root 1.297 - when not using autoconf, tighten the check for clock_gettime and related
35     functionality.
36    
37 root 1.296 4.18 Fri Sep 5 17:55:26 CEST 2014
38 root 1.295 - events on files were not always generated properly with the
39     epoll backend (testcase by Assaf Inbal).
40 root 1.288 - mark event pipe fd as cloexec after a fork (analyzed by Sami Farin).
41 root 1.289 - (ecb) support m68k, m88k and sh (patch by Miod Vallat).
42 root 1.291 - use a reasonable fallback for EV_NSIG instead of erroring out
43     when we can't detect the signal set size.
44 root 1.292 - in the absence of autoconf, do not use the clock syscall
45     on glibc >= 2.17 (avoids the syscall AND -lrt on systems
46     doing clock_gettime in userspace).
47 root 1.293 - ensure extern "C" function pointers are used for externally-visible
48     loop callbacks (not watcher callbacks yet).
49 root 1.294 - (ecb) work around memory barriers and volatile apparently both being
50     broken in visual studio 2008 and later (analysed and patch by Nicolas Noble).
51 root 1.288
52 root 1.287 4.15 Fri Mar 1 12:04:50 CET 2013
53 root 1.271 - destroying a non-default loop would stop the global waitpid
54     watcher (Denis Bilenko).
55 root 1.266 - queueing pending watchers of higher priority from a watcher now invokes
56     them in a timely fashion (reported by Denis Bilenko).
57 root 1.261 - add throw() to all libev functions that cannot throw exceptions, for
58     further code size decrease when compiling for C++.
59     - add throw () to callbacks that must not throw exceptions (allocator,
60     syserr, loop acquire/release, periodic reschedule cbs).
61 root 1.256 - fix event_base_loop return code, add event_get_callback, event_base_new,
62     event_base_get_method calls to improve libevent 1.x emulation and add
63 root 1.273 some libevent 2.x functionality (based on a patch by Jeff Davey).
64 root 1.263 - add more memory fences to fix a bug reported by Jeff Davey. Better
65     be overfenced than underprotected.
66 root 1.256 - ev_run now returns a boolean status (true meaning watchers are
67     still active).
68 root 1.252 - ev_once: undef EV_ERROR in ev_kqueue.c, to avoid clashing with
69     libev's EV_ERROR (reported by 191919).
70 root 1.253 - (ecb) add memory fence support for xlC (Darin McBride).
71     - (ecb) add memory fence support for gcc-mips (Anton Kirilov).
72 root 1.259 - (ecb) add memory fence support for gcc-alpha (Christian Weisgerber).
73 root 1.254 - work around some kernels losing file descriptors by leaking
74     the kqueue descriptor in the child.
75 root 1.282 - work around linux inotify not reporting IN_ATTRIB changes for directories
76     in many cases.
77 root 1.262 - include sys/syscall.h instead of plain syscall.h.
78 root 1.268 - check for io watcher loops in ev_verify, check for the most
79     common reported usage bug in ev_io_start.
80 sf-exg 1.286 - choose socket vs. WSASocket at compiletime using EV_USE_WSASOCKET.
81 root 1.270 - always use WSASend/WSARecv directly on windows, hoping that this
82     works in all cases (unlike read/write/send/recv...).
83 root 1.274 - try to detect signals around a fork faster (test program by
84     Denis Bilenko).
85 root 1.275 - work around recent glibc versions that leak memory in realloc.
86 root 1.276 - rename ev::embed::set to ev::embed::set_embed to avoid clashing
87     the watcher base set (loop) method.
88 root 1.278 - rewrite the async/signal pipe logic to always keep a valid fd, which
89 sf-exg 1.286 simplifies (and hopefully correctifies :) the race checking
90 root 1.278 on fork, at the cost of one extra fd.
91 root 1.282 - add fat, msdos, jffs2, ramfs, ntfs and btrfs to the list of
92     inotify-supporting filesystems.
93 root 1.283 - move orig_CFLAGS assignment to after AC_INIT, as newer autoconf
94     versions ignore it before
95     (https://bugzilla.redhat.com/show_bug.cgi?id=908096).
96 root 1.284 - add some untested android support.
97 root 1.285 - enum expressions must be of type int (reported by Juan Pablo L).
98 root 1.253
99 root 1.250 4.11 Sat Feb 4 19:52:39 CET 2012
100 root 1.248 - INCOMPATIBLE CHANGE: ev_timer_again now clears the pending status, as
101     was documented already, but not implemented in the repeating case.
102 root 1.249 - new compiletime symbols: EV_NO_SMP and EV_NO_THREADS.
103 root 1.234 - fix a race where the workaround against the epoll fork bugs
104     caused signals to not be handled anymore.
105 root 1.229 - correct backend_fudge for most backends, and implement a windows
106     specific workaround to avoid looping because we call both
107     select and Sleep, both with different time resolutions.
108 root 1.230 - document range and guarantees of ev_sleep.
109 root 1.231 - document reasonable ranges for periodics interval and offset.
110     - rename backend_fudge to backend_mintime to avoid future confusion :)
111 root 1.225 - change the default periodic reschedule function to hopefully be more
112 root 1.226 exact and correct even in corner cases or in the far future.
113 root 1.225 - do not rely on -lm anymore: use it when available but use our
114 root 1.230 own floor () if it is missing. This should make it easier to embed,
115     as no external libraries are required.
116 root 1.232 - strategically import macros from libecb and mark rarely-used functions
117 sf-exg 1.239 as cache-cold (saving almost 2k code size on typical amd64 setups).
118 root 1.237 - add Symbols.ev and Symbols.event files, that were missing.
119 root 1.242 - fix backend_mintime value for epoll (was 1/1024, is 1/1000 now).
120 root 1.244 - fix #3 "be smart about timeouts" to not "deadlock" when
121     timeout == now, also improve the section overall.
122     - avoid "AVOIDING FINISHING BEFORE RETURNING" idiom.
123 root 1.245 - support new EV_API_STATIC mode to make all libev symbols
124     static.
125 root 1.251 - supply default CFLAGS of -g -O3 with gcc when original CFLAGS
126     were empty.
127 root 1.225
128 root 1.224 4.04 Wed Feb 16 09:01:51 CET 2011
129     - fix two problems in the native win32 backend, where reuse of fd's
130     with different underlying handles caused handles not to be removed
131     or added to the select set (analyzed and tested by Bert Belder).
132 root 1.221 - do no rely on ceil() in ev_e?poll.c.
133 root 1.222 - backport libev to HP-UX versions before 11 v3.
134 root 1.223 - configure did not detect nanosleep and clock_gettime properly when
135     they are available in the libc (as opposed to -lrt).
136 root 1.221
137 root 1.219 4.03 Tue Jan 11 14:37:25 CET 2011
138 root 1.217 - officially support polling files with all backends.
139 root 1.212 - support files, /dev/zero etc. the same way as select in the epoll
140     backend, by generating events on our own.
141 root 1.217 - ports backend: work around solaris bug 6874410 and many related ones
142     (EINTR, maybe more), with no performance loss (note that the solaris
143     bug report is actually wrong, reality is far more bizarre and broken
144     than that).
145 root 1.209 - define EV_READ/EV_WRITE as macros in event.h, as some programs use
146     #ifdef to test for them.
147 root 1.213 - new (experimental) function: ev_feed_signal.
148     - new (to become default) EVFLAG_NOSIGMASK flag.
149     - new EVBACKEND_MASK symbol.
150 root 1.220 - updated COMMON IDIOMS SECTION.
151 root 1.209
152 root 1.207 4.01 Fri Nov 5 21:51:29 CET 2010
153 root 1.205 - automake fucked it up, apparently, --add-missing -f is not quite enough
154 root 1.206 to make it update its files, so 4.00 didn't install ev++.h and
155     event.h on make install. grrr.
156     - ev_loop(count|depth) didn't return anything (Robin Haberkorn).
157 root 1.203 - change EV_UNDEF to 0xffffffff to silence some overzealous compilers.
158 root 1.204 - use "(libev) " prefix for all libev error messages now.
159 root 1.203
160 root 1.202 4.00 Mon Oct 25 12:32:12 CEST 2010
161 root 1.171 - "PORTING FROM LIBEV 3.X TO 4.X" (in ev.pod) is recommended reading.
162 root 1.161 - ev_embed_stop did not correctly stop the watcher (very good
163     testcase by Vladimir Timofeev).
164 sf-exg 1.191 - ev_run will now always update the current loop time - it erroneously
165 root 1.187 didn't when idle watchers were active, causing timers not to fire.
166 root 1.179 - fix a bug where a timeout of zero caused the timer not to fire
167     in the libevent emulation (testcase by Péter Szabó).
168 root 1.164 - applied win32 fixes by Michael Lenaghan (also James Mansion).
169 root 1.166 - replace EV_MINIMAL by EV_FEATURES.
170 root 1.178 - prefer EPOLL_CTL_ADD over EPOLL_CTL_MOD in some more cases, as it
171     seems the former is *much* faster than the latter.
172 root 1.197 - linux kernel version detection (for inotify bug workarounds)
173     did not work properly.
174 root 1.185 - reduce the number of spurious wake-ups with the ports backend.
175 root 1.158 - remove dependency on sys/queue.h on freebsd (patch by Vanilla Hsu).
176 root 1.186 - do async init within ev_async_start, not ev_async_set, which avoids
177     an API quirk where the set function must be called in the C++ API
178     even when there is nothing to set.
179 root 1.174 - add (undocumented) EV_ENABLE when adding events with kqueue,
180 root 1.175 this might help with OS X, which seems to need it despite documenting
181     not to need it (helpfully pointed out by Tilghman Lesher).
182 root 1.176 - do not use poll by default on freebsd, it's broken (what isn't
183     on freebsd...).
184 root 1.195 - allow to embed epoll on kernels >= 2.6.32.
185 root 1.159 - configure now prepends -O3, not appends it, so one can still
186     override it.
187 root 1.190 - ev.pod: greatly expanded the portability section, added a porting
188     section, a description of watcher states and made lots of minor fixes.
189 root 1.160 - disable poll backend on AIX, the poll header spams the namespace
190     and it's not worth working around dead platforms (reported
191     and analyzed by Aivars Kalvans).
192 root 1.162 - improve header file compatibility of the standalone eventfd code
193     in an obscure case.
194 root 1.163 - implement EV_AVOID_STDIO option.
195     - do not use sscanf to parse linux version number (smaller, faster,
196     no sscanf dependency).
197 root 1.164 - new EV_CHILD_ENABLE and EV_SIGNAL_ENABLE configurable settings.
198 sf-exg 1.172 - update libev.m4 HAVE_CLOCK_SYSCALL test for newer glibcs.
199 root 1.165 - add section on accept() problems to the manpage.
200 root 1.168 - rename EV_TIMEOUT to EV_TIMER.
201 root 1.190 - rename ev_loop_count/depth/verify/loop/unloop.
202 root 1.197 - remove ev_default_destroy and ev_default_fork.
203 root 1.168 - switch to two-digit minor version.
204 root 1.180 - work around an apparent gentoo compiler bug.
205 root 1.181 - define _DARWIN_UNLIMITED_SELECT. just so.
206 root 1.188 - use enum instead of #define for most constants.
207     - improve compatibility to older C++ compilers.
208 root 1.193 - (experimental) ev_run/ev_default_loop/ev_break/ev_loop_new have now
209     default arguments when compiled as C++.
210 root 1.196 - enable automake dependency tracking.
211 root 1.197 - ev_loop_new no longer leaks memory when loop creation failed.
212 root 1.198 - new ev_cleanup watcher type.
213 root 1.157
214 root 1.156 3.9 Thu Dec 31 07:59:59 CET 2009
215 root 1.155 - signalfd is no longer used by default and has to be requested
216     explicitly - this means that easy to catch bugs become hard to
217     catch race conditions, but the users have spoken.
218     - point out the unspecified signal mask in the documentation, and
219     that this is a race condition regardless of EV_SIGNALFD.
220 root 1.142 - backport inotify code to C89.
221 root 1.148 - inotify file descriptors could leak into child processes.
222 sf-exg 1.241 - ev_stat watchers could keep an erroneous extra ref on the loop,
223 root 1.151 preventing exit when unregistering all watchers (testcases
224 root 1.150 provided by ry@tinyclouds.org).
225 root 1.143 - implement EV_WIN32_HANDLE_TO_FD and EV_WIN32_CLOSE_FD configuration
226 root 1.145 symbols to make it easier for apps to do their own fd management.
227 root 1.144 - support EV_IDLE_ENABLE being disabled in ev++.h
228     (patch by Didier Spezia).
229 root 1.147 - take advantage of inotify_init1, if available, to set cloexec/nonblock
230     on fd creation, to avoid races.
231 root 1.150 - the signal handling pipe wasn't always initialised under windows
232     (analysed by lekma).
233 root 1.146 - changed minimum glibc requirement from glibc 2.9 to 2.7, for
234     signalfd.
235 root 1.152 - add missing string.h include (Denis F. Latypoff).
236 root 1.153 - only replace ev_stat.prev when we detect an actual difference,
237     so prev is (almost) always different to attr. this might
238 sf-exg 1.191 have caused the problems with 04_stat.t.
239 root 1.154 - add ev::timer->remaining () method to C++ API.
240 root 1.142
241 root 1.141 3.8 Sun Aug 9 14:30:45 CEST 2009
242 root 1.133 - incompatible change: do not necessarily reset signal handler
243     to SIG_DFL when a sighandler is stopped.
244 root 1.135 - ev_default_destroy did not properly free or zero some members,
245 sf-exg 1.191 potentially causing crashes and memory corruption on repeated
246 root 1.134 ev_default_destroy/ev_default_loop calls.
247 root 1.133 - take advantage of signalfd on GNU/Linux systems.
248     - document that the signal mask might be in an unspecified
249     state when using libev's signal handling.
250 root 1.136 - take advantage of some GNU/Linux calls to set cloexec/nonblock
251     on fd creation, to avoid race conditions.
252 root 1.132
253 root 1.131 3.7 Fri Jul 17 16:36:32 CEST 2009
254 root 1.128 - ev_unloop and ev_loop wrongly used a global variable to exit loops,
255     instead of using a per-loop variable (bug caught by accident...).
256     - the ev_set_io_collect_interval interpretation has changed.
257     - add new functionality: ev_set_userdata, ev_userdata,
258 root 1.126 ev_set_invoke_pending_cb, ev_set_loop_release_cb,
259 root 1.132 ev_invoke_pending, ev_pending_count, together with a long example
260     about thread locking.
261 root 1.128 - add ev_timer_remaining (as requested by Denis F. Latypoff).
262     - add ev_loop_depth.
263 root 1.124 - calling ev_unloop in fork/prepare watchers will no longer poll
264     for new events.
265 root 1.115 - Denis F. Latypoff corrected many typos in example code snippets.
266     - honor autoconf detection of EV_USE_CLOCK_SYSCALL, also double-
267     check that the syscall number is available before trying to
268     use it (reported by ry@tinyclouds).
269 root 1.117 - use GetSystemTimeAsFileTime instead of _timeb on windows, for
270 root 1.116 slightly higher accuracy.
271 root 1.122 - properly declare ev_loop_verify and ev_now_update even when
272     !EV_MULTIPLICITY.
273 root 1.121 - do not compile in any priority code when EV_MAXPRI == EV_MINPRI.
274 root 1.123 - support EV_MINIMAL==2 for a reduced API.
275 root 1.125 - actually 0-initialise struct sigaction when installing signals.
276 root 1.127 - add section on hibernate and stopped processes to ev_timer docs.
277 root 1.115
278 root 1.113 3.6 Tue Apr 28 02:49:30 CEST 2009
279 root 1.107 - multiple timers becoming ready within an event loop iteration
280     will be invoked in the "correct" order now.
281 root 1.105 - do not leave the event loop early just because we have no active
282     watchers, fixing a problem when embedding a kqueue loop
283     that has active kernel events but no registered watchers
284     (reported by blacksand blacksand).
285 root 1.102 - correctly zero the idx values for arrays, so destroying and
286     reinitialising the default loop actually works (patch by
287     Malek Hadj-Ali).
288 root 1.108 - implement ev_suspend and ev_resume.
289 root 1.106 - new EV_CUSTOM revents flag for use by applications.
290 sf-exg 1.241 - add documentation section about priorities.
291 sf-exg 1.286 - add a glossary to the documentation.
292 root 1.111 - extend the ev_fork description slightly.
293 root 1.112 - optimize a jump out of call_pending.
294 root 1.102
295 root 1.101 3.53 Sun Feb 15 02:38:20 CET 2009
296     - fix a bug in event pipe creation on win32 that would cause a
297     failed assertion on event loop creation (patch by Malek Hadj-Ali).
298 root 1.100 - probe for CLOCK_REALTIME support at runtime as well and fall
299     back to gettimeofday if there is an error, to support older
300     operating systems with newer header files/libraries.
301     - prefer gettimeofday over clock_gettime with USE_CLOCK_SYSCALL
302     (default most everywhere), otherwise not.
303    
304 root 1.99 3.52 Wed Jan 7 21:43:02 CET 2009
305 root 1.97 - fix compilation of select backend in fd_set mode when NFDBITS is
306     missing (to get it to compile on QNX, reported by Rodrigo Campos).
307     - better select-nfds handling when select backend is in fd_set mode.
308     - diagnose fd_set overruns when select backend is in fd_set mode.
309     - due to a thinko, instead of disabling everything but
310     select on the borked OS X platform, everything but select was
311     allowed (reported by Emanuele Giaquinta).
312 root 1.95 - actually verify that local and remote port are matching in
313     libev's socketpair emulation, which makes denial-of-service
314     attacks harder (but not impossible - it's windows). Make sure
315 root 1.96 it even works under vista, which thinks that getpeer/sockname
316     should return fantasy port numbers.
317 root 1.100 - include "libev" in all assertion messages for potentially
318 root 1.97 clearer diagnostics.
319 root 1.98 - event_get_version (libevent compatibility) returned
320     a useless string instead of the expected version string
321     (patch by W.C.A. Wijngaards).
322 root 1.95
323 root 1.94 3.51 Wed Dec 24 23:00:11 CET 2008
324 root 1.91 - fix a bug where an inotify watcher was added twice, causing
325 root 1.92 freezes on hash collisions (reported and analysed by Graham Leggett).
326 root 1.87 - new config symbol, EV_USE_CLOCK_SYSCALL, to make libev use
327     a direct syscall - slower, but no dependency on librt et al.
328 root 1.88 - assume negative return values != -1 signals success of port_getn
329     (http://cvs.epicsol.org/cgi/viewcvs.cgi/epic5/source/newio.c?rev=1.52)
330     (no known failure reports, but it doesn't hurt).
331 root 1.93 - fork detection in ev_embed now stops and restarts the watcher
332     automatically.
333 root 1.89 - EXPERIMENTAL: default the method to operator () in ev++.h,
334     to make it nicer to use functors (requested by Benedek László).
335     - fixed const object callbacks in ev++.h.
336 root 1.90 - replaced loop_ref argument of watcher.set (loop) by a direct
337     ev_loop * in ev++.h, to avoid clashes with functor patch.
338 root 1.91 - do not try to watch the empty string via inotify.
339 root 1.92 - inotify watchers could be leaked under certain circumstances.
340     - OS X 10.5 is actually even more broken than earlier versions,
341     so fall back to select on that piece of garbage.
342 root 1.93 - fixed some weirdness in the ev_embed documentation.
343 root 1.87
344 root 1.86 3.49 Wed Nov 19 11:26:53 CET 2008
345 root 1.83 - ev_stat watchers will now use inotify as a mere hint on
346     kernels <2.6.25, or if the filesystem is not in the
347     "known to be good" list.
348 root 1.84 - better mingw32 compatibility (it's not as borked as native win32)
349     (analysed by Roger Pack).
350 root 1.85 - include stdio.h in the example program, as too many people are
351     confused by the weird C language otherwise. I guess the next thing
352     I get told is that the "..." ellipses in the examples don't compile
353     with their C compiler.
354 root 1.83
355 root 1.80 3.48 Thu Oct 30 09:02:37 CET 2008
356 root 1.71 - further optimise away the EPOLL_CTL_ADD/MOD combo in the epoll
357     backend by assuming the kernel event mask hasn't changed if
358     ADD fails with EEXIST.
359 root 1.75 - work around spurious event notification bugs in epoll by using
360 root 1.77 a 32-bit generation counter. recreate kernel state if we receive
361 root 1.78 spurious notifications or unwanted events. this is very costly,
362     but I didn't come up with this horrible design.
363 root 1.71 - use memset to initialise most arrays now and do away with the
364     init functions.
365 root 1.72 - expand time-out strategies into a "Be smart about timeouts" section.
366     - drop the "struct" from all ev_watcher declarations in the
367 root 1.73 documentation and did other clarifications (yeah, it was a mistake
368     to have a struct AND a function called ev_loop).
369 root 1.74 - fix a bug where ev_default would not initialise the default
370     loop again after it was destroyed with ev_default_destroy.
371 root 1.79 - rename syserr to ev_syserr to avoid name clashes when embedding,
372     do similar changes for event.c.
373 root 1.71
374 root 1.69 3.45 Tue Oct 21 21:59:26 CEST 2008
375 root 1.67 - disable inotify usage on linux <2.6.25, as it is broken
376     (reported by Yoann Vandoorselaere).
377 sf-exg 1.191 - ev_stat erroneously would try to add inotify watchers
378 root 1.68 even when inotify wasn't available (this should only
379 root 1.67 have a performance impact).
380 root 1.65 - ev_once now passes both timeout and io to the callback if both
381     occur concurrently, instead of giving timeouts precedence.
382 root 1.66 - disable EV_USE_INOTIFY when sys/inotify.h is too old.
383 root 1.65
384 root 1.62 3.44 Mon Sep 29 05:18:39 CEST 2008
385     - embed watchers now automatically invoke ev_loop_fork on the
386     embedded loop when the parent loop forks.
387 root 1.58 - new function: ev_now_update (loop).
388 root 1.57 - verify_watcher was not marked static.
389 root 1.59 - improve the "associating..." manpage section.
390 root 1.60 - documentation tweaks here and there.
391 root 1.57
392 root 1.56 3.43 Sun Jul 6 05:34:41 CEST 2008
393 root 1.54 - include more include files on windows to get struct _stati64
394 root 1.56 (reported by Chris Hulbert, but doesn't quite fix his issue).
395 root 1.53 - add missing #include <io.h> in ev.c on windows (reported by
396     Matt Tolton).
397    
398 root 1.52 3.42 Tue Jun 17 12:12:07 CEST 2008
399 root 1.50 - work around yet another windows bug: FD_SET actually adds fd's
400     multiple times to the fd_*SET*, despite official MSN docs claiming
401 root 1.51 otherwise. Reported and well-analysed by Matt Tolton.
402     - define NFDBITS to 0 when EV_SELECT_IS_WINSOCKET to make it compile
403 root 1.48 (reported any analysed by Chris Hulbert).
404 root 1.49 - fix a bug in ev_ebadf (this function is only used to catch
405     programming errors in the libev user). reported by Matt Tolton.
406     - fix a bug in fd_intern on win32 (could lead to compile errors
407     under some circumstances, but would work correctly if it compiles).
408     reported by Matt Tolton.
409 root 1.50 - (try to) work around missing lstat on windows.
410 root 1.45 - pass in the write fd set as except fd set under windows. windows
411 root 1.46 is so uncontrollably lame that it requires this. this means that
412     switching off oobinline is not supported (but tcp/ip doesn't
413     have oob, so that would be stupid anyways.
414 root 1.47 - use posix module symbol to auto-detect monotonic clock presence
415     and some other default values.
416 root 1.45
417 root 1.44 3.41 Fri May 23 18:42:54 CEST 2008
418 root 1.46 - work around an obscure bug in winsocket select: if you
419 root 1.40 provide only empty fd sets then select returns WSAEINVAL. how sucky.
420 root 1.41 - improve timer scheduling stability and reduce use of time_epsilon.
421 root 1.36 - use 1-based 2-heap for EV_MINIMAL, simplifies code, reduces
422     codesize and makes for better cache-efficiency.
423     - use 3-based 4-heap for !EV_MINIMAL. this makes better use
424     of cpu cache lines and gives better growth behaviour than
425     2-based heaps.
426 root 1.38 - cache timestamp within heap for !EV_MINIMAL, to avoid random
427     memory accesses.
428     - document/add EV_USE_4HEAP and EV_HEAP_CACHE_AT.
429 root 1.33 - fix a potential aliasing issue in ev_timer_again.

431     - improve ev_stat docs.
432     - add portability requirements section.
433 root 1.39 - fix manpage headers etc.
434 root 1.40 - normalise WSA error codes to lower range on windows.
435 root 1.43 - add consistency check code that can be called automatically
436     or on demand to check for internal structures (ev_loop_verify).
437 root 1.31
438 root 1.30 3.31 Wed Apr 16 20:45:04 CEST 2008
439     - added last minute fix for ev_poll.c by Brandon Black.
440 root 1.29
441 root 1.28 3.3 Wed Apr 16 19:04:10 CEST 2008
442 root 1.23 - event_base_loopexit should return 0 on success
443     (W.C.A. Wijngaards).
444 root 1.20 - added linux eventfd support.
445     - try to autodetect epoll and inotify support
446     by libc header version if not using autoconf.
447 root 1.21 - new symbols: EV_DEFAULT_UC and EV_DEFAULT_UC_.
448     - declare functions defined in ev.h as inline if
449     C99 or gcc are available.
450     - enable inlining with gcc versions 2 and 3.
451 root 1.25 - work around broken poll implementations potentially
452     not clearing revents field in ev_poll (Brandon Black)
453     (no such systems are known at this time).
454 root 1.23 - work around a bug in realloc on openbsd and darwin,
455 sf-exg 1.191 also makes the erroneous valgrind complaints
456 root 1.23 go away (noted by various people).
457 root 1.26 - fix ev_async_pending, add c++ wrapper for ev_async
458 sf-exg 1.191 (based on patch sent by Johannes Deisenhofer).
459 root 1.26 - add sensible set method to ev::embed.
460 root 1.27 - made integer constants type int in ev.h.
461 root 1.20
462 root 1.19 3.2 Wed Apr 2 17:11:19 CEST 2008
463 root 1.15 - fix a 64 bit overflow issue in the select backend,
464     by using fd_mask instead of int for the mask.
465 root 1.16 - rename internal sighandler to avoid clash with very old perls.
466 root 1.18 - entering ev_loop will not clear the ONESHOT or NONBLOCKING
467     flags of any outer loops anymore.
468 root 1.17 - add ev_async_pending.
469 root 1.15
470 root 1.14 3.1 Thu Mar 13 13:45:22 CET 2008
