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

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