# 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 1.316 - move the darwin select workaround highe rin ev.c, as newre versions of
4     darwin managed to break their broken select even more.
5 root 1.314 - ANDROID => __ANDROID__ (reported by enh@google.com).
6 root 1.315 - disable epoll_create1 on android because it has broken header files
7     and google is unwilling to fix them (reported by enh@google.com).
8 root 1.317 - avoid a minor compilation warning on win32.
9 root 1.319 - c++: rename EV_THROW to EV_NOEXCEPT.
10 root 1.318 - c++: remove deprecated dynamic throw() specifications.
11     - c++: improve the (unsupported) bad_loop exception class.
12 root 1.319 - backport perl ev_periodic example to C, untested.
13 root 1.314
14 root 1.313 4.24 Wed Dec 28 05:19:55 CET 2016
15     - bump version to 4.24, as the release tarball inexplicably
16     didn't have the right version in ev.h, even though the cvs-tagged
17     version did have the right one (reported by Ales Teska).
18    
19 root 1.312 4.23 Wed Nov 16 18:23:41 CET 2016
20 root 1.311 - move some declarations at the beginning to help certain retarded
21     microsoft compilers, even though their documentation claims
22     otherwise (reported by Ruslan Osmanov).
23    
24 root 1.310 4.22 Sun Dec 20 22:11:50 CET 2015
25 root 1.308 - when epoll detects unremovable fds in the fd set, rebuild
26     only the epoll descriptor, not the signal pipe, to avoid
27     SIGPIPE in ev_async_send. This doesn't solve it on fork,
28     so document what needs to be done in ev_loop_fork
29     (analyzed by Benjamin Mahler).
30     - remove superfluous sys/timeb.h include on win32
31     (analyzed by Jason Madden).
32 root 1.309 - updated libecb.
33 root 1.308
34 root 1.307 4.20 Sat Jun 20 13:01:43 CEST 2015
35 root 1.302 - prefer noexcept over throw () with C++ 11.
36 root 1.303 - update ecb.h due to incompatibilities with c11.
37 root 1.305 - fix a potential aliasing issue when reading and writing
38 root 1.304 watcher callbacks.
39 root 1.301
40 root 1.300 4.19 Thu Sep 25 08:18:25 CEST 2014
41 root 1.298 - ev.h wasn't valid C++ anymore, which tripped compilers other than
42 root 1.299 clang, msvc or gcc (analyzed by Raphael 'kena' Poss). Unfortunately,
43     C++ doesn't support typedefs for function pointers fully, so the affected
44     declarations have to spell out the types each time.
45 root 1.297 - when not using autoconf, tighten the check for clock_gettime and related
46     functionality.
47    
48 root 1.296 4.18 Fri Sep 5 17:55:26 CEST 2014
49 root 1.295 - events on files were not always generated properly with the
50     epoll backend (testcase by Assaf Inbal).
51 root 1.288 - mark event pipe fd as cloexec after a fork (analyzed by Sami Farin).
52 root 1.289 - (ecb) support m68k, m88k and sh (patch by Miod Vallat).
53 root 1.291 - use a reasonable fallback for EV_NSIG instead of erroring out
54     when we can't detect the signal set size.
55 root 1.292 - in the absence of autoconf, do not use the clock syscall
56     on glibc >= 2.17 (avoids the syscall AND -lrt on systems
57     doing clock_gettime in userspace).
58 root 1.293 - ensure extern "C" function pointers are used for externally-visible
59     loop callbacks (not watcher callbacks yet).
60 root 1.294 - (ecb) work around memory barriers and volatile apparently both being
61     broken in visual studio 2008 and later (analysed and patch by Nicolas Noble).
62 root 1.288
63 root 1.287 4.15 Fri Mar 1 12:04:50 CET 2013
64 root 1.271 - destroying a non-default loop would stop the global waitpid
65     watcher (Denis Bilenko).
66 root 1.266 - queueing pending watchers of higher priority from a watcher now invokes
67     them in a timely fashion (reported by Denis Bilenko).
68 root 1.261 - add throw() to all libev functions that cannot throw exceptions, for
69     further code size decrease when compiling for C++.
70     - add throw () to callbacks that must not throw exceptions (allocator,
71     syserr, loop acquire/release, periodic reschedule cbs).
72 root 1.256 - fix event_base_loop return code, add event_get_callback, event_base_new,
73     event_base_get_method calls to improve libevent 1.x emulation and add
74 root 1.273 some libevent 2.x functionality (based on a patch by Jeff Davey).
75 root 1.263 - add more memory fences to fix a bug reported by Jeff Davey. Better
76     be overfenced than underprotected.
77 root 1.256 - ev_run now returns a boolean status (true meaning watchers are
78     still active).
79 root 1.252 - ev_once: undef EV_ERROR in ev_kqueue.c, to avoid clashing with
80     libev's EV_ERROR (reported by 191919).
81 root 1.253 - (ecb) add memory fence support for xlC (Darin McBride).
82     - (ecb) add memory fence support for gcc-mips (Anton Kirilov).
83 root 1.259 - (ecb) add memory fence support for gcc-alpha (Christian Weisgerber).
84 root 1.254 - work around some kernels losing file descriptors by leaking
85     the kqueue descriptor in the child.
86 root 1.282 - work around linux inotify not reporting IN_ATTRIB changes for directories
87     in many cases.
88 root 1.262 - include sys/syscall.h instead of plain syscall.h.
89 root 1.268 - check for io watcher loops in ev_verify, check for the most
90     common reported usage bug in ev_io_start.
91 sf-exg 1.286 - choose socket vs. WSASocket at compiletime using EV_USE_WSASOCKET.
92 root 1.270 - always use WSASend/WSARecv directly on windows, hoping that this
93     works in all cases (unlike read/write/send/recv...).
94 root 1.274 - try to detect signals around a fork faster (test program by
95     Denis Bilenko).
96 root 1.275 - work around recent glibc versions that leak memory in realloc.
97 root 1.276 - rename ev::embed::set to ev::embed::set_embed to avoid clashing
98     the watcher base set (loop) method.
99 root 1.278 - rewrite the async/signal pipe logic to always keep a valid fd, which
100 sf-exg 1.286 simplifies (and hopefully correctifies :) the race checking
101 root 1.278 on fork, at the cost of one extra fd.
102 root 1.282 - add fat, msdos, jffs2, ramfs, ntfs and btrfs to the list of
103     inotify-supporting filesystems.
104 root 1.283 - move orig_CFLAGS assignment to after AC_INIT, as newer autoconf
105     versions ignore it before
106     (https://bugzilla.redhat.com/show_bug.cgi?id=908096).
107 root 1.284 - add some untested android support.
108 root 1.285 - enum expressions must be of type int (reported by Juan Pablo L).
109 root 1.253
110 root 1.250 4.11 Sat Feb 4 19:52:39 CET 2012
111 root 1.248 - INCOMPATIBLE CHANGE: ev_timer_again now clears the pending status, as
112     was documented already, but not implemented in the repeating case.
113 root 1.249 - new compiletime symbols: EV_NO_SMP and EV_NO_THREADS.
114 root 1.234 - fix a race where the workaround against the epoll fork bugs
115     caused signals to not be handled anymore.
116 root 1.229 - correct backend_fudge for most backends, and implement a windows
117     specific workaround to avoid looping because we call both
118     select and Sleep, both with different time resolutions.
119 root 1.230 - document range and guarantees of ev_sleep.
120 root 1.231 - document reasonable ranges for periodics interval and offset.
121     - rename backend_fudge to backend_mintime to avoid future confusion :)
122 root 1.225 - change the default periodic reschedule function to hopefully be more
123 root 1.226 exact and correct even in corner cases or in the far future.
124 root 1.225 - do not rely on -lm anymore: use it when available but use our
125 root 1.230 own floor () if it is missing. This should make it easier to embed,
126     as no external libraries are required.
127 root 1.232 - strategically import macros from libecb and mark rarely-used functions
128 sf-exg 1.239 as cache-cold (saving almost 2k code size on typical amd64 setups).
129 root 1.237 - add Symbols.ev and Symbols.event files, that were missing.
130 root 1.242 - fix backend_mintime value for epoll (was 1/1024, is 1/1000 now).
131 root 1.244 - fix #3 "be smart about timeouts" to not "deadlock" when
132     timeout == now, also improve the section overall.
133     - avoid "AVOIDING FINISHING BEFORE RETURNING" idiom.
134 root 1.245 - support new EV_API_STATIC mode to make all libev symbols
135     static.
136 root 1.251 - supply default CFLAGS of -g -O3 with gcc when original CFLAGS
137     were empty.
138 root 1.225
139 root 1.224 4.04 Wed Feb 16 09:01:51 CET 2011
140     - fix two problems in the native win32 backend, where reuse of fd's
141     with different underlying handles caused handles not to be removed
142     or added to the select set (analyzed and tested by Bert Belder).
143 root 1.221 - do no rely on ceil() in ev_e?poll.c.
144 root 1.222 - backport libev to HP-UX versions before 11 v3.
145 root 1.223 - configure did not detect nanosleep and clock_gettime properly when
146     they are available in the libc (as opposed to -lrt).
147 root 1.221
148 root 1.219 4.03 Tue Jan 11 14:37:25 CET 2011
149 root 1.217 - officially support polling files with all backends.
150 root 1.212 - support files, /dev/zero etc. the same way as select in the epoll
151     backend, by generating events on our own.
152 root 1.217 - ports backend: work around solaris bug 6874410 and many related ones
153     (EINTR, maybe more), with no performance loss (note that the solaris
154     bug report is actually wrong, reality is far more bizarre and broken
155     than that).
156 root 1.209 - define EV_READ/EV_WRITE as macros in event.h, as some programs use
157     #ifdef to test for them.
158 root 1.213 - new (experimental) function: ev_feed_signal.
159     - new (to become default) EVFLAG_NOSIGMASK flag.
160     - new EVBACKEND_MASK symbol.
161 root 1.220 - updated COMMON IDIOMS SECTION.
162 root 1.209
163 root 1.207 4.01 Fri Nov 5 21:51:29 CET 2010
164 root 1.205 - automake fucked it up, apparently, --add-missing -f is not quite enough
165 root 1.206 to make it update its files, so 4.00 didn't install ev++.h and
166     event.h on make install. grrr.
167     - ev_loop(count|depth) didn't return anything (Robin Haberkorn).
168 root 1.203 - change EV_UNDEF to 0xffffffff to silence some overzealous compilers.
169 root 1.204 - use "(libev) " prefix for all libev error messages now.
170 root 1.203
171 root 1.202 4.00 Mon Oct 25 12:32:12 CEST 2010
172 root 1.171 - "PORTING FROM LIBEV 3.X TO 4.X" (in ev.pod) is recommended reading.
173 root 1.161 - ev_embed_stop did not correctly stop the watcher (very good
174     testcase by Vladimir Timofeev).
175 sf-exg 1.191 - ev_run will now always update the current loop time - it erroneously
176 root 1.187 didn't when idle watchers were active, causing timers not to fire.
177 root 1.179 - fix a bug where a timeout of zero caused the timer not to fire
178     in the libevent emulation (testcase by Péter Szabó).
179 root 1.164 - applied win32 fixes by Michael Lenaghan (also James Mansion).
180 root 1.166 - replace EV_MINIMAL by EV_FEATURES.
181 root 1.178 - prefer EPOLL_CTL_ADD over EPOLL_CTL_MOD in some more cases, as it
182     seems the former is *much* faster than the latter.
183 root 1.197 - linux kernel version detection (for inotify bug workarounds)
184     did not work properly.
185 root 1.185 - reduce the number of spurious wake-ups with the ports backend.
186 root 1.158 - remove dependency on sys/queue.h on freebsd (patch by Vanilla Hsu).
187 root 1.186 - do async init within ev_async_start, not ev_async_set, which avoids
188     an API quirk where the set function must be called in the C++ API
189     even when there is nothing to set.
190 root 1.174 - add (undocumented) EV_ENABLE when adding events with kqueue,
191 root 1.175 this might help with OS X, which seems to need it despite documenting
192     not to need it (helpfully pointed out by Tilghman Lesher).
193 root 1.176 - do not use poll by default on freebsd, it's broken (what isn't
194     on freebsd...).
195 root 1.195 - allow to embed epoll on kernels >= 2.6.32.
196 root 1.159 - configure now prepends -O3, not appends it, so one can still
197     override it.
198 root 1.190 - ev.pod: greatly expanded the portability section, added a porting
199     section, a description of watcher states and made lots of minor fixes.
200 root 1.160 - disable poll backend on AIX, the poll header spams the namespace
201     and it's not worth working around dead platforms (reported
202     and analyzed by Aivars Kalvans).
203 root 1.162 - improve header file compatibility of the standalone eventfd code
204     in an obscure case.
205 root 1.163 - implement EV_AVOID_STDIO option.
206     - do not use sscanf to parse linux version number (smaller, faster,
207     no sscanf dependency).
208 root 1.164 - new EV_CHILD_ENABLE and EV_SIGNAL_ENABLE configurable settings.
209 sf-exg 1.172 - update libev.m4 HAVE_CLOCK_SYSCALL test for newer glibcs.
210 root 1.165 - add section on accept() problems to the manpage.
211 root 1.168 - rename EV_TIMEOUT to EV_TIMER.
212 root 1.190 - rename ev_loop_count/depth/verify/loop/unloop.
213 root 1.197 - remove ev_default_destroy and ev_default_fork.
214 root 1.168 - switch to two-digit minor version.
215 root 1.180 - work around an apparent gentoo compiler bug.
216 root 1.181 - define _DARWIN_UNLIMITED_SELECT. just so.
217 root 1.188 - use enum instead of #define for most constants.
218     - improve compatibility to older C++ compilers.
219 root 1.193 - (experimental) ev_run/ev_default_loop/ev_break/ev_loop_new have now
220     default arguments when compiled as C++.
221 root 1.196 - enable automake dependency tracking.
222 root 1.197 - ev_loop_new no longer leaks memory when loop creation failed.
223 root 1.198 - new ev_cleanup watcher type.
224 root 1.157
225 root 1.156 3.9 Thu Dec 31 07:59:59 CET 2009
226 root 1.155 - signalfd is no longer used by default and has to be requested
227     explicitly - this means that easy to catch bugs become hard to
228     catch race conditions, but the users have spoken.
229     - point out the unspecified signal mask in the documentation, and
230     that this is a race condition regardless of EV_SIGNALFD.
231 root 1.142 - backport inotify code to C89.
232 root 1.148 - inotify file descriptors could leak into child processes.
233 sf-exg 1.241 - ev_stat watchers could keep an erroneous extra ref on the loop,
234 root 1.151 preventing exit when unregistering all watchers (testcases
235 root 1.150 provided by ry@tinyclouds.org).
236 root 1.143 - implement EV_WIN32_HANDLE_TO_FD and EV_WIN32_CLOSE_FD configuration
237 root 1.145 symbols to make it easier for apps to do their own fd management.
238 root 1.144 - support EV_IDLE_ENABLE being disabled in ev++.h
239     (patch by Didier Spezia).
240 root 1.147 - take advantage of inotify_init1, if available, to set cloexec/nonblock
241     on fd creation, to avoid races.
242 root 1.150 - the signal handling pipe wasn't always initialised under windows
243     (analysed by lekma).
244 root 1.146 - changed minimum glibc requirement from glibc 2.9 to 2.7, for
245     signalfd.
246 root 1.152 - add missing string.h include (Denis F. Latypoff).
247 root 1.153 - only replace ev_stat.prev when we detect an actual difference,
248     so prev is (almost) always different to attr. this might
249 sf-exg 1.191 have caused the problems with 04_stat.t.
250 root 1.154 - add ev::timer->remaining () method to C++ API.
251 root 1.142
252 root 1.141 3.8 Sun Aug 9 14:30:45 CEST 2009
253 root 1.133 - incompatible change: do not necessarily reset signal handler
254     to SIG_DFL when a sighandler is stopped.
255 root 1.135 - ev_default_destroy did not properly free or zero some members,
256 sf-exg 1.191 potentially causing crashes and memory corruption on repeated
257 root 1.134 ev_default_destroy/ev_default_loop calls.
258 root 1.133 - take advantage of signalfd on GNU/Linux systems.
259     - document that the signal mask might be in an unspecified
260     state when using libev's signal handling.
261 root 1.136 - take advantage of some GNU/Linux calls to set cloexec/nonblock
262     on fd creation, to avoid race conditions.
263 root 1.132
264 root 1.131 3.7 Fri Jul 17 16:36:32 CEST 2009
265 root 1.128 - ev_unloop and ev_loop wrongly used a global variable to exit loops,
266     instead of using a per-loop variable (bug caught by accident...).
267     - the ev_set_io_collect_interval interpretation has changed.
268     - add new functionality: ev_set_userdata, ev_userdata,
269 root 1.126 ev_set_invoke_pending_cb, ev_set_loop_release_cb,
270 root 1.132 ev_invoke_pending, ev_pending_count, together with a long example
271     about thread locking.
272 root 1.128 - add ev_timer_remaining (as requested by Denis F. Latypoff).
273     - add ev_loop_depth.
274 root 1.124 - calling ev_unloop in fork/prepare watchers will no longer poll
275     for new events.
276 root 1.115 - Denis F. Latypoff corrected many typos in example code snippets.
277     - honor autoconf detection of EV_USE_CLOCK_SYSCALL, also double-
278     check that the syscall number is available before trying to
279     use it (reported by ry@tinyclouds).
280 root 1.117 - use GetSystemTimeAsFileTime instead of _timeb on windows, for
281 root 1.116 slightly higher accuracy.
282 root 1.122 - properly declare ev_loop_verify and ev_now_update even when
283     !EV_MULTIPLICITY.
284 root 1.121 - do not compile in any priority code when EV_MAXPRI == EV_MINPRI.
285 root 1.123 - support EV_MINIMAL==2 for a reduced API.
286 root 1.125 - actually 0-initialise struct sigaction when installing signals.
287 root 1.127 - add section on hibernate and stopped processes to ev_timer docs.
288 root 1.115
289 root 1.113 3.6 Tue Apr 28 02:49:30 CEST 2009
290 root 1.107 - multiple timers becoming ready within an event loop iteration
291     will be invoked in the "correct" order now.
292 root 1.105 - do not leave the event loop early just because we have no active
293     watchers, fixing a problem when embedding a kqueue loop
294     that has active kernel events but no registered watchers
295     (reported by blacksand blacksand).
296 root 1.102 - correctly zero the idx values for arrays, so destroying and
297     reinitialising the default loop actually works (patch by
298     Malek Hadj-Ali).
299 root 1.108 - implement ev_suspend and ev_resume.
300 root 1.106 - new EV_CUSTOM revents flag for use by applications.
301 sf-exg 1.241 - add documentation section about priorities.
302 sf-exg 1.286 - add a glossary to the documentation.
303 root 1.111 - extend the ev_fork description slightly.
304 root 1.112 - optimize a jump out of call_pending.
305 root 1.102
306 root 1.101 3.53 Sun Feb 15 02:38:20 CET 2009
307     - fix a bug in event pipe creation on win32 that would cause a
308     failed assertion on event loop creation (patch by Malek Hadj-Ali).
309 root 1.100 - probe for CLOCK_REALTIME support at runtime as well and fall
310     back to gettimeofday if there is an error, to support older
311     operating systems with newer header files/libraries.
312     - prefer gettimeofday over clock_gettime with USE_CLOCK_SYSCALL
313     (default most everywhere), otherwise not.
314    
315 root 1.99 3.52 Wed Jan 7 21:43:02 CET 2009
316 root 1.97 - fix compilation of select backend in fd_set mode when NFDBITS is
317     missing (to get it to compile on QNX, reported by Rodrigo Campos).
318     - better select-nfds handling when select backend is in fd_set mode.
319     - diagnose fd_set overruns when select backend is in fd_set mode.
320     - due to a thinko, instead of disabling everything but
321     select on the borked OS X platform, everything but select was
322     allowed (reported by Emanuele Giaquinta).
323 root 1.95 - actually verify that local and remote port are matching in
324     libev's socketpair emulation, which makes denial-of-service
325     attacks harder (but not impossible - it's windows). Make sure
326 root 1.96 it even works under vista, which thinks that getpeer/sockname
327     should return fantasy port numbers.
328 root 1.100 - include "libev" in all assertion messages for potentially
329 root 1.97 clearer diagnostics.
330 root 1.98 - event_get_version (libevent compatibility) returned
331     a useless string instead of the expected version string
332     (patch by W.C.A. Wijngaards).
333 root 1.95
334 root 1.94 3.51 Wed Dec 24 23:00:11 CET 2008
335 root 1.91 - fix a bug where an inotify watcher was added twice, causing
336 root 1.92 freezes on hash collisions (reported and analysed by Graham Leggett).
337 root 1.87 - new config symbol, EV_USE_CLOCK_SYSCALL, to make libev use
338     a direct syscall - slower, but no dependency on librt et al.
339 root 1.88 - assume negative return values != -1 signals success of port_getn
340     (http://cvs.epicsol.org/cgi/viewcvs.cgi/epic5/source/newio.c?rev=1.52)
341     (no known failure reports, but it doesn't hurt).
342 root 1.93 - fork detection in ev_embed now stops and restarts the watcher
343     automatically.
344 root 1.89 - EXPERIMENTAL: default the method to operator () in ev++.h,
345     to make it nicer to use functors (requested by Benedek László).
346     - fixed const object callbacks in ev++.h.
347 root 1.90 - replaced loop_ref argument of watcher.set (loop) by a direct
348     ev_loop * in ev++.h, to avoid clashes with functor patch.
349 root 1.91 - do not try to watch the empty string via inotify.
350 root 1.92 - inotify watchers could be leaked under certain circumstances.
351     - OS X 10.5 is actually even more broken than earlier versions,
352     so fall back to select on that piece of garbage.
353 root 1.93 - fixed some weirdness in the ev_embed documentation.
354 root 1.87
355 root 1.86 3.49 Wed Nov 19 11:26:53 CET 2008
356 root 1.83 - ev_stat watchers will now use inotify as a mere hint on
357     kernels <2.6.25, or if the filesystem is not in the
358     "known to be good" list.
359 root 1.84 - better mingw32 compatibility (it's not as borked as native win32)
360     (analysed by Roger Pack).
361 root 1.85 - include stdio.h in the example program, as too many people are
362     confused by the weird C language otherwise. I guess the next thing
363     I get told is that the "..." ellipses in the examples don't compile
364     with their C compiler.
365 root 1.83
366 root 1.80 3.48 Thu Oct 30 09:02:37 CET 2008
367 root 1.71 - further optimise away the EPOLL_CTL_ADD/MOD combo in the epoll
368     backend by assuming the kernel event mask hasn't changed if
369     ADD fails with EEXIST.
370 root 1.75 - work around spurious event notification bugs in epoll by using
371 root 1.77 a 32-bit generation counter. recreate kernel state if we receive
372 root 1.78 spurious notifications or unwanted events. this is very costly,
373     but I didn't come up with this horrible design.
374 root 1.71 - use memset to initialise most arrays now and do away with the
375     init functions.
376 root 1.72 - expand time-out strategies into a "Be smart about timeouts" section.
377     - drop the "struct" from all ev_watcher declarations in the
378 root 1.73 documentation and did other clarifications (yeah, it was a mistake
379     to have a struct AND a function called ev_loop).
380 root 1.74 - fix a bug where ev_default would not initialise the default
381     loop again after it was destroyed with ev_default_destroy.
382 root 1.79 - rename syserr to ev_syserr to avoid name clashes when embedding,
383     do similar changes for event.c.
384 root 1.71
385 root 1.69 3.45 Tue Oct 21 21:59:26 CEST 2008
386 root 1.67 - disable inotify usage on linux <2.6.25, as it is broken
387     (reported by Yoann Vandoorselaere).
388 sf-exg 1.191 - ev_stat erroneously would try to add inotify watchers
389 root 1.68 even when inotify wasn't available (this should only
390 root 1.67 have a performance impact).
391 root 1.65 - ev_once now passes both timeout and io to the callback if both
392     occur concurrently, instead of giving timeouts precedence.
393 root 1.66 - disable EV_USE_INOTIFY when sys/inotify.h is too old.
394 root 1.65

408    
409 root 1.52 3.42 Tue Jun 17 12:12:07 CEST 2008
410 root 1.50 - work around yet another windows bug: FD_SET actually adds fd's
411     multiple times to the fd_*SET*, despite official MSN docs claiming
412 root 1.51 otherwise. Reported and well-analysed by Matt Tolton.
413     - define NFDBITS to 0 when EV_SELECT_IS_WINSOCKET to make it compile
414 root 1.48 (reported any analysed by Chris Hulbert).
415 root 1.49 - fix a bug in ev_ebadf (this function is only used to catch
416     programming errors in the libev user). reported by Matt Tolton.
417     - fix a bug in fd_intern on win32 (could lead to compile errors
418     under some circumstances, but would work correctly if it compiles).
419     reported by Matt Tolton.
420 root 1.50 - (try to) work around missing lstat on windows.
421 root 1.45 - pass in the write fd set as except fd set under windows. windows
422 root 1.46 is so uncontrollably lame that it requires this. this means that
423     switching off oobinline is not supported (but tcp/ip doesn't
424     have oob, so that would be stupid anyways.
425 root 1.47 - use posix module symbol to auto-detect monotonic clock presence
426     and some other default values.
427 root 1.45
428 root 1.44 3.41 Fri May 23 18:42:54 CEST 2008
429 root 1.46 - work around an obscure bug in winsocket select: if you
430 root 1.40 provide only empty fd sets then select returns WSAEINVAL. how sucky.
431 root 1.41 - improve timer scheduling stability and reduce use of time_epsilon.
432 root 1.36 - use 1-based 2-heap for EV_MINIMAL, simplifies code, reduces
433     codesize and makes for better cache-efficiency.
434     - use 3-based 4-heap for !EV_MINIMAL. this makes better use
435     of cpu cache lines and gives better growth behaviour than
436     2-based heaps.
437 root 1.38 - cache timestamp within heap for !EV_MINIMAL, to avoid random
438     memory accesses.
439     - document/add EV_USE_4HEAP and EV_HEAP_CACHE_AT.

456     - try to autodetect epoll and inotify support
457     by libc header version if not using autoconf.

462 root 1.25 - work around broken poll implementations potentially
463     not clearing revents field in ev_poll (Brandon Black)
464     (no such systems are known at this time).
465 root 1.23 - work around a bug in realloc on openbsd and darwin,
466 sf-exg 1.191 also makes the erroneous valgrind complaints
467 root 1.23 go away (noted by various people).
468 root 1.26 - fix ev_async_pending, add c++ wrapper for ev_async

476 root 1.16 - rename internal sighandler to avoid clash with very old perls.
477 root 1.18 - entering ev_loop will not clear the ONESHOT or NONBLOCKING
