# 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 1.324 - removed redundant 0-ptr check in ev_once.
4    
5 root 1.320 4.25 Fri Dec 21 07:49:20 CET 2018
6     - INCOMPATIBLE CHANGE: EV_THROW was renamed to EV_NOEXCEPT
7 root 1.323 (EV_THROW still provided) and now uses noexcept on C++11 or newer.
8 root 1.320 - move the darwin select workaround highe rin ev.c, as newer versions of
9 root 1.316 darwin managed to break their broken select even more.
10 root 1.314 - ANDROID => __ANDROID__ (reported by enh@google.com).
11 root 1.315 - disable epoll_create1 on android because it has broken header files
12     and google is unwilling to fix them (reported by enh@google.com).
13 root 1.317 - avoid a minor compilation warning on win32.
14 root 1.318 - c++: remove deprecated dynamic throw() specifications.
15     - c++: improve the (unsupported) bad_loop exception class.
16 root 1.319 - backport perl ev_periodic example to C, untested.
17 root 1.321 - update libecb, biggets change is to include a memory fence
18     in ECB_MEMORY_FENCE_RELEASE on x86/amd64.
19 root 1.322 - minor autoconf/automake modernisation.
20 root 1.314
21 root 1.313 4.24 Wed Dec 28 05:19:55 CET 2016
22     - bump version to 4.24, as the release tarball inexplicably
23     didn't have the right version in ev.h, even though the cvs-tagged
24     version did have the right one (reported by Ales Teska).
25    
26 root 1.312 4.23 Wed Nov 16 18:23:41 CET 2016
27 root 1.311 - move some declarations at the beginning to help certain retarded
28     microsoft compilers, even though their documentation claims
29     otherwise (reported by Ruslan Osmanov).
30    
31 root 1.310 4.22 Sun Dec 20 22:11:50 CET 2015
32 root 1.308 - when epoll detects unremovable fds in the fd set, rebuild
33     only the epoll descriptor, not the signal pipe, to avoid
34     SIGPIPE in ev_async_send. This doesn't solve it on fork,
35     so document what needs to be done in ev_loop_fork
36     (analyzed by Benjamin Mahler).
37     - remove superfluous sys/timeb.h include on win32
38     (analyzed by Jason Madden).
39 root 1.309 - updated libecb.
40 root 1.308
41 root 1.307 4.20 Sat Jun 20 13:01:43 CEST 2015
42 root 1.302 - prefer noexcept over throw () with C++ 11.
43 root 1.303 - update ecb.h due to incompatibilities with c11.
44 root 1.305 - fix a potential aliasing issue when reading and writing
45 root 1.304 watcher callbacks.
46 root 1.301
47 root 1.300 4.19 Thu Sep 25 08:18:25 CEST 2014
48 root 1.298 - ev.h wasn't valid C++ anymore, which tripped compilers other than
49 root 1.299 clang, msvc or gcc (analyzed by Raphael 'kena' Poss). Unfortunately,
50     C++ doesn't support typedefs for function pointers fully, so the affected
51     declarations have to spell out the types each time.
52 root 1.297 - when not using autoconf, tighten the check for clock_gettime and related
53     functionality.
54    
55 root 1.296 4.18 Fri Sep 5 17:55:26 CEST 2014
56 root 1.295 - events on files were not always generated properly with the
57     epoll backend (testcase by Assaf Inbal).
58 root 1.288 - mark event pipe fd as cloexec after a fork (analyzed by Sami Farin).
59 root 1.289 - (ecb) support m68k, m88k and sh (patch by Miod Vallat).
60 root 1.291 - use a reasonable fallback for EV_NSIG instead of erroring out
61     when we can't detect the signal set size.
62 root 1.292 - in the absence of autoconf, do not use the clock syscall
63     on glibc >= 2.17 (avoids the syscall AND -lrt on systems
64     doing clock_gettime in userspace).
65 root 1.293 - ensure extern "C" function pointers are used for externally-visible
66     loop callbacks (not watcher callbacks yet).
67 root 1.294 - (ecb) work around memory barriers and volatile apparently both being
68     broken in visual studio 2008 and later (analysed and patch by Nicolas Noble).
69 root 1.288
70 root 1.287 4.15 Fri Mar 1 12:04:50 CET 2013
71 root 1.271 - destroying a non-default loop would stop the global waitpid
72     watcher (Denis Bilenko).
73 root 1.266 - queueing pending watchers of higher priority from a watcher now invokes
74     them in a timely fashion (reported by Denis Bilenko).
75 root 1.261 - add throw() to all libev functions that cannot throw exceptions, for
76     further code size decrease when compiling for C++.
77     - add throw () to callbacks that must not throw exceptions (allocator,
78     syserr, loop acquire/release, periodic reschedule cbs).
79 root 1.256 - fix event_base_loop return code, add event_get_callback, event_base_new,
80     event_base_get_method calls to improve libevent 1.x emulation and add
81 root 1.273 some libevent 2.x functionality (based on a patch by Jeff Davey).
82 root 1.263 - add more memory fences to fix a bug reported by Jeff Davey. Better
83     be overfenced than underprotected.
84 root 1.256 - ev_run now returns a boolean status (true meaning watchers are
85     still active).
86 root 1.252 - ev_once: undef EV_ERROR in ev_kqueue.c, to avoid clashing with
87     libev's EV_ERROR (reported by 191919).
88 root 1.253 - (ecb) add memory fence support for xlC (Darin McBride).
89     - (ecb) add memory fence support for gcc-mips (Anton Kirilov).
90 root 1.259 - (ecb) add memory fence support for gcc-alpha (Christian Weisgerber).
91 root 1.254 - work around some kernels losing file descriptors by leaking
92     the kqueue descriptor in the child.
93 root 1.282 - work around linux inotify not reporting IN_ATTRIB changes for directories
94     in many cases.
95 root 1.262 - include sys/syscall.h instead of plain syscall.h.
96 root 1.268 - check for io watcher loops in ev_verify, check for the most
97     common reported usage bug in ev_io_start.
98 sf-exg 1.286 - choose socket vs. WSASocket at compiletime using EV_USE_WSASOCKET.
99 root 1.270 - always use WSASend/WSARecv directly on windows, hoping that this
100     works in all cases (unlike read/write/send/recv...).
101 root 1.274 - try to detect signals around a fork faster (test program by
102     Denis Bilenko).
103 root 1.275 - work around recent glibc versions that leak memory in realloc.
104 root 1.276 - rename ev::embed::set to ev::embed::set_embed to avoid clashing
105     the watcher base set (loop) method.
106 root 1.278 - rewrite the async/signal pipe logic to always keep a valid fd, which
107 sf-exg 1.286 simplifies (and hopefully correctifies :) the race checking
108 root 1.278 on fork, at the cost of one extra fd.
109 root 1.282 - add fat, msdos, jffs2, ramfs, ntfs and btrfs to the list of
110     inotify-supporting filesystems.
111 root 1.283 - move orig_CFLAGS assignment to after AC_INIT, as newer autoconf
112     versions ignore it before
113     (https://bugzilla.redhat.com/show_bug.cgi?id=908096).
114 root 1.284 - add some untested android support.
115 root 1.285 - enum expressions must be of type int (reported by Juan Pablo L).
116 root 1.253
117 root 1.250 4.11 Sat Feb 4 19:52:39 CET 2012
118 root 1.248 - INCOMPATIBLE CHANGE: ev_timer_again now clears the pending status, as
119     was documented already, but not implemented in the repeating case.
120 root 1.249 - new compiletime symbols: EV_NO_SMP and EV_NO_THREADS.
121 root 1.234 - fix a race where the workaround against the epoll fork bugs
122     caused signals to not be handled anymore.
123 root 1.229 - correct backend_fudge for most backends, and implement a windows
124     specific workaround to avoid looping because we call both
125     select and Sleep, both with different time resolutions.
126 root 1.230 - document range and guarantees of ev_sleep.
127 root 1.231 - document reasonable ranges for periodics interval and offset.
128     - rename backend_fudge to backend_mintime to avoid future confusion :)
129 root 1.225 - change the default periodic reschedule function to hopefully be more
130 root 1.226 exact and correct even in corner cases or in the far future.
131 root 1.225 - do not rely on -lm anymore: use it when available but use our
132 root 1.230 own floor () if it is missing. This should make it easier to embed,
133     as no external libraries are required.
134 root 1.232 - strategically import macros from libecb and mark rarely-used functions
135 sf-exg 1.239 as cache-cold (saving almost 2k code size on typical amd64 setups).
136 root 1.237 - add Symbols.ev and Symbols.event files, that were missing.
137 root 1.242 - fix backend_mintime value for epoll (was 1/1024, is 1/1000 now).
138 root 1.244 - fix #3 "be smart about timeouts" to not "deadlock" when
139     timeout == now, also improve the section overall.
140     - avoid "AVOIDING FINISHING BEFORE RETURNING" idiom.
141 root 1.245 - support new EV_API_STATIC mode to make all libev symbols
142     static.
143 root 1.251 - supply default CFLAGS of -g -O3 with gcc when original CFLAGS
144     were empty.
145 root 1.225
146 root 1.224 4.04 Wed Feb 16 09:01:51 CET 2011
147     - fix two problems in the native win32 backend, where reuse of fd's
148     with different underlying handles caused handles not to be removed
149     or added to the select set (analyzed and tested by Bert Belder).
150 root 1.221 - do no rely on ceil() in ev_e?poll.c.
151 root 1.222 - backport libev to HP-UX versions before 11 v3.
152 root 1.223 - configure did not detect nanosleep and clock_gettime properly when
153     they are available in the libc (as opposed to -lrt).
154 root 1.221
155 root 1.219 4.03 Tue Jan 11 14:37:25 CET 2011
156 root 1.217 - officially support polling files with all backends.
157 root 1.212 - support files, /dev/zero etc. the same way as select in the epoll
158     backend, by generating events on our own.
159 root 1.217 - ports backend: work around solaris bug 6874410 and many related ones
160     (EINTR, maybe more), with no performance loss (note that the solaris
161     bug report is actually wrong, reality is far more bizarre and broken
162     than that).
163 root 1.209 - define EV_READ/EV_WRITE as macros in event.h, as some programs use
164     #ifdef to test for them.
165 root 1.213 - new (experimental) function: ev_feed_signal.
166     - new (to become default) EVFLAG_NOSIGMASK flag.
167     - new EVBACKEND_MASK symbol.
168 root 1.220 - updated COMMON IDIOMS SECTION.
169 root 1.209
170 root 1.207 4.01 Fri Nov 5 21:51:29 CET 2010
171 root 1.205 - automake fucked it up, apparently, --add-missing -f is not quite enough
172 root 1.206 to make it update its files, so 4.00 didn't install ev++.h and
173     event.h on make install. grrr.
174     - ev_loop(count|depth) didn't return anything (Robin Haberkorn).
175 root 1.203 - change EV_UNDEF to 0xffffffff to silence some overzealous compilers.
176 root 1.204 - use "(libev) " prefix for all libev error messages now.
177 root 1.203
178 root 1.202 4.00 Mon Oct 25 12:32:12 CEST 2010
179 root 1.171 - "PORTING FROM LIBEV 3.X TO 4.X" (in ev.pod) is recommended reading.
180 root 1.161 - ev_embed_stop did not correctly stop the watcher (very good
181     testcase by Vladimir Timofeev).
182 sf-exg 1.191 - ev_run will now always update the current loop time - it erroneously
183 root 1.187 didn't when idle watchers were active, causing timers not to fire.
184 root 1.179 - fix a bug where a timeout of zero caused the timer not to fire
185     in the libevent emulation (testcase by Péter Szabó).
186 root 1.164 - applied win32 fixes by Michael Lenaghan (also James Mansion).
187 root 1.166 - replace EV_MINIMAL by EV_FEATURES.
188 root 1.178 - prefer EPOLL_CTL_ADD over EPOLL_CTL_MOD in some more cases, as it
189     seems the former is *much* faster than the latter.
190 root 1.197 - linux kernel version detection (for inotify bug workarounds)
191     did not work properly.
192 root 1.185 - reduce the number of spurious wake-ups with the ports backend.
193 root 1.158 - remove dependency on sys/queue.h on freebsd (patch by Vanilla Hsu).
194 root 1.186 - do async init within ev_async_start, not ev_async_set, which avoids
195     an API quirk where the set function must be called in the C++ API
196     even when there is nothing to set.
197 root 1.174 - add (undocumented) EV_ENABLE when adding events with kqueue,
198 root 1.175 this might help with OS X, which seems to need it despite documenting
199     not to need it (helpfully pointed out by Tilghman Lesher).
200 root 1.176 - do not use poll by default on freebsd, it's broken (what isn't
201     on freebsd...).
202 root 1.195 - allow to embed epoll on kernels >= 2.6.32.
203 root 1.159 - configure now prepends -O3, not appends it, so one can still
204     override it.
205 root 1.190 - ev.pod: greatly expanded the portability section, added a porting
206     section, a description of watcher states and made lots of minor fixes.
207 root 1.160 - disable poll backend on AIX, the poll header spams the namespace
208     and it's not worth working around dead platforms (reported
209     and analyzed by Aivars Kalvans).
210 root 1.162 - improve header file compatibility of the standalone eventfd code
211     in an obscure case.
212 root 1.163 - implement EV_AVOID_STDIO option.
213     - do not use sscanf to parse linux version number (smaller, faster,
214     no sscanf dependency).
215 root 1.164 - new EV_CHILD_ENABLE and EV_SIGNAL_ENABLE configurable settings.
216 sf-exg 1.172 - update libev.m4 HAVE_CLOCK_SYSCALL test for newer glibcs.
217 root 1.165 - add section on accept() problems to the manpage.
218 root 1.168 - rename EV_TIMEOUT to EV_TIMER.
219 root 1.190 - rename ev_loop_count/depth/verify/loop/unloop.
220 root 1.197 - remove ev_default_destroy and ev_default_fork.
221 root 1.168 - switch to two-digit minor version.
222 root 1.180 - work around an apparent gentoo compiler bug.
223 root 1.181 - define _DARWIN_UNLIMITED_SELECT. just so.
224 root 1.188 - use enum instead of #define for most constants.
225     - improve compatibility to older C++ compilers.
226 root 1.193 - (experimental) ev_run/ev_default_loop/ev_break/ev_loop_new have now
227     default arguments when compiled as C++.
228 root 1.196 - enable automake dependency tracking.
229 root 1.197 - ev_loop_new no longer leaks memory when loop creation failed.
230 root 1.198 - new ev_cleanup watcher type.
231 root 1.157
232 root 1.156 3.9 Thu Dec 31 07:59:59 CET 2009
233 root 1.155 - signalfd is no longer used by default and has to be requested
234     explicitly - this means that easy to catch bugs become hard to
235     catch race conditions, but the users have spoken.
236     - point out the unspecified signal mask in the documentation, and
237     that this is a race condition regardless of EV_SIGNALFD.
238 root 1.142 - backport inotify code to C89.
239 root 1.148 - inotify file descriptors could leak into child processes.
240 sf-exg 1.241 - ev_stat watchers could keep an erroneous extra ref on the loop,
241 root 1.151 preventing exit when unregistering all watchers (testcases
242 root 1.150 provided by ry@tinyclouds.org).
243 root 1.143 - implement EV_WIN32_HANDLE_TO_FD and EV_WIN32_CLOSE_FD configuration
244 root 1.145 symbols to make it easier for apps to do their own fd management.
245 root 1.144 - support EV_IDLE_ENABLE being disabled in ev++.h
246     (patch by Didier Spezia).
247 root 1.147 - take advantage of inotify_init1, if available, to set cloexec/nonblock
248     on fd creation, to avoid races.
249 root 1.150 - the signal handling pipe wasn't always initialised under windows
250     (analysed by lekma).
251 root 1.146 - changed minimum glibc requirement from glibc 2.9 to 2.7, for
252     signalfd.
253 root 1.152 - add missing string.h include (Denis F. Latypoff).
254 root 1.153 - only replace ev_stat.prev when we detect an actual difference,
255     so prev is (almost) always different to attr. this might
256 sf-exg 1.191 have caused the problems with 04_stat.t.
257 root 1.154 - add ev::timer->remaining () method to C++ API.
258 root 1.142
259 root 1.141 3.8 Sun Aug 9 14:30:45 CEST 2009
260 root 1.133 - incompatible change: do not necessarily reset signal handler
261     to SIG_DFL when a sighandler is stopped.
262 root 1.135 - ev_default_destroy did not properly free or zero some members,
263 sf-exg 1.191 potentially causing crashes and memory corruption on repeated
264 root 1.134 ev_default_destroy/ev_default_loop calls.
265 root 1.133 - take advantage of signalfd on GNU/Linux systems.
266     - document that the signal mask might be in an unspecified
267     state when using libev's signal handling.
268 root 1.136 - take advantage of some GNU/Linux calls to set cloexec/nonblock
269     on fd creation, to avoid race conditions.
270 root 1.132
271 root 1.131 3.7 Fri Jul 17 16:36:32 CEST 2009
272 root 1.128 - ev_unloop and ev_loop wrongly used a global variable to exit loops,
273     instead of using a per-loop variable (bug caught by accident...).
274     - the ev_set_io_collect_interval interpretation has changed.
275     - add new functionality: ev_set_userdata, ev_userdata,
276 root 1.126 ev_set_invoke_pending_cb, ev_set_loop_release_cb,
277 root 1.132 ev_invoke_pending, ev_pending_count, together with a long example
278     about thread locking.
279 root 1.128 - add ev_timer_remaining (as requested by Denis F. Latypoff).
280     - add ev_loop_depth.
281 root 1.124 - calling ev_unloop in fork/prepare watchers will no longer poll
282     for new events.
283 root 1.115 - Denis F. Latypoff corrected many typos in example code snippets.
284     - honor autoconf detection of EV_USE_CLOCK_SYSCALL, also double-
285     check that the syscall number is available before trying to
286     use it (reported by ry@tinyclouds).
287 root 1.117 - use GetSystemTimeAsFileTime instead of _timeb on windows, for
288 root 1.116 slightly higher accuracy.
289 root 1.122 - properly declare ev_loop_verify and ev_now_update even when
290     !EV_MULTIPLICITY.
291 root 1.121 - do not compile in any priority code when EV_MAXPRI == EV_MINPRI.
292 root 1.123 - support EV_MINIMAL==2 for a reduced API.
293 root 1.125 - actually 0-initialise struct sigaction when installing signals.
294 root 1.127 - add section on hibernate and stopped processes to ev_timer docs.
295 root 1.115
296 root 1.113 3.6 Tue Apr 28 02:49:30 CEST 2009
297 root 1.107 - multiple timers becoming ready within an event loop iteration
298     will be invoked in the "correct" order now.
299 root 1.105 - do not leave the event loop early just because we have no active
300     watchers, fixing a problem when embedding a kqueue loop
301     that has active kernel events but no registered watchers
302     (reported by blacksand blacksand).
303 root 1.102 - correctly zero the idx values for arrays, so destroying and
304     reinitialising the default loop actually works (patch by
305     Malek Hadj-Ali).
306 root 1.108 - implement ev_suspend and ev_resume.
307 root 1.106 - new EV_CUSTOM revents flag for use by applications.
308 sf-exg 1.241 - add documentation section about priorities.
309 sf-exg 1.286 - add a glossary to the documentation.
310 root 1.111 - extend the ev_fork description slightly.
311 root 1.112 - optimize a jump out of call_pending.
312 root 1.102
313 root 1.101 3.53 Sun Feb 15 02:38:20 CET 2009
314     - fix a bug in event pipe creation on win32 that would cause a
315     failed assertion on event loop creation (patch by Malek Hadj-Ali).
316 root 1.100 - probe for CLOCK_REALTIME support at runtime as well and fall
317     back to gettimeofday if there is an error, to support older
318     operating systems with newer header files/libraries.
319     - prefer gettimeofday over clock_gettime with USE_CLOCK_SYSCALL
320     (default most everywhere), otherwise not.
321    
322 root 1.99 3.52 Wed Jan 7 21:43:02 CET 2009
323 root 1.97 - fix compilation of select backend in fd_set mode when NFDBITS is
324     missing (to get it to compile on QNX, reported by Rodrigo Campos).
325     - better select-nfds handling when select backend is in fd_set mode.
326     - diagnose fd_set overruns when select backend is in fd_set mode.
327     - due to a thinko, instead of disabling everything but
328     select on the borked OS X platform, everything but select was
329     allowed (reported by Emanuele Giaquinta).
330 root 1.95 - actually verify that local and remote port are matching in
331     libev's socketpair emulation, which makes denial-of-service
332     attacks harder (but not impossible - it's windows). Make sure
333 root 1.96 it even works under vista, which thinks that getpeer/sockname
334     should return fantasy port numbers.
335 root 1.100 - include "libev" in all assertion messages for potentially
336 root 1.97 clearer diagnostics.
337 root 1.98 - event_get_version (libevent compatibility) returned
338     a useless string instead of the expected version string
339     (patch by W.C.A. Wijngaards).
340 root 1.95
341 root 1.94 3.51 Wed Dec 24 23:00:11 CET 2008
342 root 1.91 - fix a bug where an inotify watcher was added twice, causing
343 root 1.92 freezes on hash collisions (reported and analysed by Graham Leggett).
344 root 1.87 - new config symbol, EV_USE_CLOCK_SYSCALL, to make libev use
345     a direct syscall - slower, but no dependency on librt et al.
346 root 1.88 - assume negative return values != -1 signals success of port_getn
347     (http://cvs.epicsol.org/cgi/viewcvs.cgi/epic5/source/newio.c?rev=1.52)
348     (no known failure reports, but it doesn't hurt).
349 root 1.93 - fork detection in ev_embed now stops and restarts the watcher
350     automatically.
351 root 1.89 - EXPERIMENTAL: default the method to operator () in ev++.h,
352     to make it nicer to use functors (requested by Benedek László).
353     - fixed const object callbacks in ev++.h.
354 root 1.90 - replaced loop_ref argument of watcher.set (loop) by a direct
355     ev_loop * in ev++.h, to avoid clashes with functor patch.
356 root 1.91 - do not try to watch the empty string via inotify.
357 root 1.92 - inotify watchers could be leaked under certain circumstances.
358     - OS X 10.5 is actually even more broken than earlier versions,
359     so fall back to select on that piece of garbage.
360 root 1.93 - fixed some weirdness in the ev_embed documentation.
361 root 1.87
362 root 1.86 3.49 Wed Nov 19 11:26:53 CET 2008
363 root 1.83 - ev_stat watchers will now use inotify as a mere hint on
364     kernels <2.6.25, or if the filesystem is not in the
365     "known to be good" list.
366 root 1.84 - better mingw32 compatibility (it's not as borked as native win32)
367     (analysed by Roger Pack).
368 root 1.85 - include stdio.h in the example program, as too many people are
369     confused by the weird C language otherwise. I guess the next thing
370     I get told is that the "..." ellipses in the examples don't compile
371     with their C compiler.
372 root 1.83
373 root 1.80 3.48 Thu Oct 30 09:02:37 CET 2008
374 root 1.71 - further optimise away the EPOLL_CTL_ADD/MOD combo in the epoll
375     backend by assuming the kernel event mask hasn't changed if
376     ADD fails with EEXIST.
377 root 1.75 - work around spurious event notification bugs in epoll by using
378 root 1.77 a 32-bit generation counter. recreate kernel state if we receive
379 root 1.78 spurious notifications or unwanted events. this is very costly,
380     but I didn't come up with this horrible design.
381 root 1.71 - use memset to initialise most arrays now and do away with the
382     init functions.
383 root 1.72 - expand time-out strategies into a "Be smart about timeouts" section.
384     - drop the "struct" from all ev_watcher declarations in the
385 root 1.73 documentation and did other clarifications (yeah, it was a mistake
386     to have a struct AND a function called ev_loop).
387 root 1.74 - fix a bug where ev_default would not initialise the default
388     loop again after it was destroyed with ev_default_destroy.
389 root 1.79 - rename syserr to ev_syserr to avoid name clashes when embedding,
390     do similar changes for event.c.
391 root 1.71
392 root 1.69 3.45 Tue Oct 21 21:59:26 CEST 2008
393 root 1.67 - disable inotify usage on linux <2.6.25, as it is broken
394     (reported by Yoann Vandoorselaere).
395 sf-exg 1.191 - ev_stat erroneously would try to add inotify watchers
396 root 1.68 even when inotify wasn't available (this should only
397 root 1.67 have a performance impact).
398 root 1.65 - ev_once now passes both timeout and io to the callback if both
399     occur concurrently, instead of giving timeouts precedence.
400 root 1.66 - disable EV_USE_INOTIFY when sys/inotify.h is too old.
401 root 1.65
402 root 1.62 3.44 Mon Sep 29 05:18:39 CEST 2008
403     - embed watchers now automatically invoke ev_loop_fork on the
404     embedded loop when the parent loop forks.
405 root 1.58 - new function: ev_now_update (loop).
406 root 1.57 - verify_watcher was not marked static.
407 root 1.59 - improve the "associating..." manpage section.
408 root 1.60 - documentation tweaks here and there.
409 root 1.57
410 root 1.56 3.43 Sun Jul 6 05:34:41 CEST 2008
411 root 1.54 - include more include files on windows to get struct _stati64
412 root 1.56 (reported by Chris Hulbert, but doesn't quite fix his issue).
413 root 1.53 - add missing #include <io.h> in ev.c on windows (reported by
414     Matt Tolton).
415    
416 root 1.52 3.42 Tue Jun 17 12:12:07 CEST 2008
417 root 1.50 - work around yet another windows bug: FD_SET actually adds fd's
418     multiple times to the fd_*SET*, despite official MSN docs claiming
419 root 1.51 otherwise. Reported and well-analysed by Matt Tolton.
420     - define NFDBITS to 0 when EV_SELECT_IS_WINSOCKET to make it compile
421 root 1.48 (reported any analysed by Chris Hulbert).
422 root 1.49 - fix a bug in ev_ebadf (this function is only used to catch
423     programming errors in the libev user). reported by Matt Tolton.
424     - fix a bug in fd_intern on win32 (could lead to compile errors
425     under some circumstances, but would work correctly if it compiles).
426     reported by Matt Tolton.
427 root 1.50 - (try to) work around missing lstat on windows.
428 root 1.45 - pass in the write fd set as except fd set under windows. windows
429 root 1.46 is so uncontrollably lame that it requires this. this means that
430     switching off oobinline is not supported (but tcp/ip doesn't
431     have oob, so that would be stupid anyways.
432 root 1.47 - use posix module symbol to auto-detect monotonic clock presence
433     and some other default values.
434 root 1.45
435 root 1.44 3.41 Fri May 23 18:42:54 CEST 2008
436 root 1.46 - work around an obscure bug in winsocket select: if you
437 root 1.40 provide only empty fd sets then select returns WSAEINVAL. how sucky.
438 root 1.41 - improve timer scheduling stability and reduce use of time_epsilon.
439 root 1.36 - use 1-based 2-heap for EV_MINIMAL, simplifies code, reduces
440     codesize and makes for better cache-efficiency.
441     - use 3-based 4-heap for !EV_MINIMAL. this makes better use
442     of cpu cache lines and gives better growth behaviour than
443     2-based heaps.
444 root 1.38 - cache timestamp within heap for !EV_MINIMAL, to avoid random
445     memory accesses.
446     - document/add EV_USE_4HEAP and EV_HEAP_CACHE_AT.
447 root 1.33 - fix a potential aliasing issue in ev_timer_again.
448 root 1.35 - add/document ev_periodic_at, retract direct access to ->at.
449     - improve ev_stat docs.
450     - add portability requirements section.
451 root 1.39 - fix manpage headers etc.
452 root 1.40 - normalise WSA error codes to lower range on windows.
453 root 1.43 - add consistency check code that can be called automatically
454     or on demand to check for internal structures (ev_loop_verify).
455 root 1.31
456 root 1.30 3.31 Wed Apr 16 20:45:04 CEST 2008
457     - added last minute fix for ev_poll.c by Brandon Black.
458 root 1.29
459 root 1.28 3.3 Wed Apr 16 19:04:10 CEST 2008
460 root 1.23 - event_base_loopexit should return 0 on success
461     (W.C.A. Wijngaards).
462 root 1.20 - added linux eventfd support.
463     - try to autodetect epoll and inotify support
464     by libc header version if not using autoconf.
465 root 1.21 - new symbols: EV_DEFAULT_UC and EV_DEFAULT_UC_.
466     - declare functions defined in ev.h as inline if
467     C99 or gcc are available.
468     - enable inlining with gcc versions 2 and 3.
469 root 1.25 - work around broken poll implementations potentially
470     not clearing revents field in ev_poll (Brandon Black)
471     (no such systems are known at this time).
472 root 1.23 - work around a bug in realloc on openbsd and darwin,
473 sf-exg 1.191 also makes the erroneous valgrind complaints
474 root 1.23 go away (noted by various people).
475 root 1.26 - fix ev_async_pending, add c++ wrapper for ev_async
476 sf-exg 1.191 (based on patch sent by Johannes Deisenhofer).
477 root 1.26 - add sensible set method to ev::embed.
478 root 1.27 - made integer constants type int in ev.h.
479 root 1.20
480 root 1.19 3.2 Wed Apr 2 17:11:19 CEST 2008
481 root 1.15 - fix a 64 bit overflow issue in the select backend,
482     by using fd_mask instead of int for the mask.
483 root 1.16 - rename internal sighandler to avoid clash with very old perls.
484 root 1.18 - entering ev_loop will not clear the ONESHOT or NONBLOCKING
485     flags of any outer loops anymore.
486 root 1.17 - add ev_async_pending.
487 root 1.15
488 root 1.14 3.1 Thu Mar 13 13:45:22 CET 2008
489 root 1.12 - implement ev_async watchers.
490 root 1.10 - only initialise signal pipe on demand.
491     - make use of sig_atomic_t configurable.
492 root 1.14 - improved documentation.
493 root 1.10
494 root 1.9 3.0 Mon Jan 28 13:14:47 CET 2008
495 root 1.6 - API/ABI bump to version 3.0.
496 root 1.4 - ev++.h includes "ev.h" by default now, not <ev.h>.
497     - slightly improved documentation.
498 root 1.5 - speed up signal detection after a fork.
499 root 1.6 - only optionally return trace status changed in ev_child
500     watchers.
