1 root 1.14 Revision history for libev, a high-performance and full-featured event loop.
2 root 1.1
3 root 1.320 4.25 Fri Dec 21 07:49:20 CET 2018
4     - INCOMPATIBLE CHANGE: EV_THROW was renamed to EV_NOEXCEPT
5 root 1.323 (EV_THROW still provided) and now uses noexcept on C++11 or newer.
6 root 1.320 - move the darwin select workaround highe rin ev.c, as newer versions of
7 root 1.316 darwin managed to break their broken select even more.
8 root 1.314 - ANDROID => __ANDROID__ (reported by enh@google.com).
9 root 1.315 - disable epoll_create1 on android because it has broken header files
10     and google is unwilling to fix them (reported by enh@google.com).
11 root 1.317 - avoid a minor compilation warning on win32.
12 root 1.318 - c++: remove deprecated dynamic throw() specifications.
13     - c++: improve the (unsupported) bad_loop exception class.
14 root 1.319 - backport perl ev_periodic example to C, untested.
15 root 1.321 - update libecb, biggets change is to include a memory fence
16     in ECB_MEMORY_FENCE_RELEASE on x86/amd64.
17 root 1.322 - minor autoconf/automake modernisation.
18 root 1.314
19 root 1.313 4.24 Wed Dec 28 05:19:55 CET 2016
20     - bump version to 4.24, as the release tarball inexplicably
21     didn't have the right version in ev.h, even though the cvs-tagged
22     version did have the right one (reported by Ales Teska).
23    
24 root 1.312 4.23 Wed Nov 16 18:23:41 CET 2016
25 root 1.311 - move some declarations at the beginning to help certain retarded
26     microsoft compilers, even though their documentation claims
27     otherwise (reported by Ruslan Osmanov).
28    
29 root 1.310 4.22 Sun Dec 20 22:11:50 CET 2015
30 root 1.308 - when epoll detects unremovable fds in the fd set, rebuild
31     only the epoll descriptor, not the signal pipe, to avoid
32     SIGPIPE in ev_async_send. This doesn't solve it on fork,
33     so document what needs to be done in ev_loop_fork
34     (analyzed by Benjamin Mahler).
35     - remove superfluous sys/timeb.h include on win32
36     (analyzed by Jason Madden).
37 root 1.309 - updated libecb.
38 root 1.308
39 root 1.307 4.20 Sat Jun 20 13:01:43 CEST 2015
40 root 1.302 - prefer noexcept over throw () with C++ 11.
41 root 1.303 - update ecb.h due to incompatibilities with c11.
42 root 1.305 - fix a potential aliasing issue when reading and writing
43 root 1.304 watcher callbacks.
44 root 1.301
45 root 1.300 4.19 Thu Sep 25 08:18:25 CEST 2014
46 root 1.298 - ev.h wasn't valid C++ anymore, which tripped compilers other than
47 root 1.299 clang, msvc or gcc (analyzed by Raphael 'kena' Poss). Unfortunately,
48     C++ doesn't support typedefs for function pointers fully, so the affected
49     declarations have to spell out the types each time.
50 root 1.297 - when not using autoconf, tighten the check for clock_gettime and related
51     functionality.
52    
53 root 1.296 4.18 Fri Sep 5 17:55:26 CEST 2014
54 root 1.295 - events on files were not always generated properly with the
55     epoll backend (testcase by Assaf Inbal).
56 root 1.288 - mark event pipe fd as cloexec after a fork (analyzed by Sami Farin).
57 root 1.289 - (ecb) support m68k, m88k and sh (patch by Miod Vallat).
58 root 1.291 - use a reasonable fallback for EV_NSIG instead of erroring out
59     when we can't detect the signal set size.
60 root 1.292 - in the absence of autoconf, do not use the clock syscall
61     on glibc >= 2.17 (avoids the syscall AND -lrt on systems
62     doing clock_gettime in userspace).
63 root 1.293 - ensure extern "C" function pointers are used for externally-visible
64     loop callbacks (not watcher callbacks yet).
65 root 1.294 - (ecb) work around memory barriers and volatile apparently both being
66     broken in visual studio 2008 and later (analysed and patch by Nicolas Noble).
67 root 1.288
68 root 1.287 4.15 Fri Mar 1 12:04:50 CET 2013
69 root 1.271 - destroying a non-default loop would stop the global waitpid
70     watcher (Denis Bilenko).
71 root 1.266 - queueing pending watchers of higher priority from a watcher now invokes
72     them in a timely fashion (reported by Denis Bilenko).
73 root 1.261 - add throw() to all libev functions that cannot throw exceptions, for
74     further code size decrease when compiling for C++.
75     - add throw () to callbacks that must not throw exceptions (allocator,
76     syserr, loop acquire/release, periodic reschedule cbs).
77 root 1.256 - fix event_base_loop return code, add event_get_callback, event_base_new,
78     event_base_get_method calls to improve libevent 1.x emulation and add
79 root 1.273 some libevent 2.x functionality (based on a patch by Jeff Davey).
80 root 1.263 - add more memory fences to fix a bug reported by Jeff Davey. Better
81     be overfenced than underprotected.
82 root 1.256 - ev_run now returns a boolean status (true meaning watchers are
83     still active).
84 root 1.252 - ev_once: undef EV_ERROR in ev_kqueue.c, to avoid clashing with
85     libev's EV_ERROR (reported by 191919).
86 root 1.253 - (ecb) add memory fence support for xlC (Darin McBride).
87     - (ecb) add memory fence support for gcc-mips (Anton Kirilov).
88 root 1.259 - (ecb) add memory fence support for gcc-alpha (Christian Weisgerber).
89 root 1.254 - work around some kernels losing file descriptors by leaking
90     the kqueue descriptor in the child.
91 root 1.282 - work around linux inotify not reporting IN_ATTRIB changes for directories
92     in many cases.
93 root 1.262 - include sys/syscall.h instead of plain syscall.h.
94 root 1.268 - check for io watcher loops in ev_verify, check for the most
95     common reported usage bug in ev_io_start.
96 sf-exg 1.286 - choose socket vs. WSASocket at compiletime using EV_USE_WSASOCKET.
97 root 1.270 - always use WSASend/WSARecv directly on windows, hoping that this
98     works in all cases (unlike read/write/send/recv...).
99 root 1.274 - try to detect signals around a fork faster (test program by
100     Denis Bilenko).
101 root 1.275 - work around recent glibc versions that leak memory in realloc.
102 root 1.276 - rename ev::embed::set to ev::embed::set_embed to avoid clashing
103     the watcher base set (loop) method.
104 root 1.278 - rewrite the async/signal pipe logic to always keep a valid fd, which
105 sf-exg 1.286 simplifies (and hopefully correctifies :) the race checking
106 root 1.278 on fork, at the cost of one extra fd.
107 root 1.282 - add fat, msdos, jffs2, ramfs, ntfs and btrfs to the list of
108     inotify-supporting filesystems.
109 root 1.283 - move orig_CFLAGS assignment to after AC_INIT, as newer autoconf
110     versions ignore it before
111     (https://bugzilla.redhat.com/show_bug.cgi?id=908096).
112 root 1.284 - add some untested android support.
113 root 1.285 - enum expressions must be of type int (reported by Juan Pablo L).
114 root 1.253
115 root 1.250 4.11 Sat Feb 4 19:52:39 CET 2012
116 root 1.248 - INCOMPATIBLE CHANGE: ev_timer_again now clears the pending status, as
117     was documented already, but not implemented in the repeating case.
118 root 1.249 - new compiletime symbols: EV_NO_SMP and EV_NO_THREADS.
119 root 1.234 - fix a race where the workaround against the epoll fork bugs
120     caused signals to not be handled anymore.
121 root 1.229 - correct backend_fudge for most backends, and implement a windows
122     specific workaround to avoid looping because we call both
123     select and Sleep, both with different time resolutions.
124 root 1.230 - document range and guarantees of ev_sleep.
125 root 1.231 - document reasonable ranges for periodics interval and offset.
126     - rename backend_fudge to backend_mintime to avoid future confusion :)
127 root 1.225 - change the default periodic reschedule function to hopefully be more
128 root 1.226 exact and correct even in corner cases or in the far future.
129 root 1.225 - do not rely on -lm anymore: use it when available but use our
130 root 1.230 own floor () if it is missing. This should make it easier to embed,
131     as no external libraries are required.
132 root 1.232 - strategically import macros from libecb and mark rarely-used functions
133 sf-exg 1.239 as cache-cold (saving almost 2k code size on typical amd64 setups).
134 root 1.237 - add Symbols.ev and Symbols.event files, that were missing.
135 root 1.242 - fix backend_mintime value for epoll (was 1/1024, is 1/1000 now).
136 root 1.244 - fix #3 "be smart about timeouts" to not "deadlock" when
137     timeout == now, also improve the section overall.
138     - avoid "AVOIDING FINISHING BEFORE RETURNING" idiom.
139 root 1.245 - support new EV_API_STATIC mode to make all libev symbols
140     static.
141 root 1.251 - supply default CFLAGS of -g -O3 with gcc when original CFLAGS
142     were empty.
143 root 1.225
144 root 1.224 4.04 Wed Feb 16 09:01:51 CET 2011
145     - fix two problems in the native win32 backend, where reuse of fd's
146     with different underlying handles caused handles not to be removed
147     or added to the select set (analyzed and tested by Bert Belder).
148 root 1.221 - do no rely on ceil() in ev_e?poll.c.
149 root 1.222 - backport libev to HP-UX versions before 11 v3.
150 root 1.223 - configure did not detect nanosleep and clock_gettime properly when
151     they are available in the libc (as opposed to -lrt).
152 root 1.221
153 root 1.219 4.03 Tue Jan 11 14:37:25 CET 2011
154 root 1.217 - officially support polling files with all backends.
155 root 1.212 - support files, /dev/zero etc. the same way as select in the epoll
156     backend, by generating events on our own.
157 root 1.217 - ports backend: work around solaris bug 6874410 and many related ones
158     (EINTR, maybe more), with no performance loss (note that the solaris
159     bug report is actually wrong, reality is far more bizarre and broken
160     than that).
161 root 1.209 - define EV_READ/EV_WRITE as macros in event.h, as some programs use
162     #ifdef to test for them.
163 root 1.213 - new (experimental) function: ev_feed_signal.
164     - new (to become default) EVFLAG_NOSIGMASK flag.
165     - new EVBACKEND_MASK symbol.
166 root 1.220 - updated COMMON IDIOMS SECTION.
167 root 1.209
168 root 1.207 4.01 Fri Nov 5 21:51:29 CET 2010
169 root 1.205 - automake fucked it up, apparently, --add-missing -f is not quite enough
170 root 1.206 to make it update its files, so 4.00 didn't install ev++.h and
171     event.h on make install. grrr.
172     - ev_loop(count|depth) didn't return anything (Robin Haberkorn).
173 root 1.203 - change EV_UNDEF to 0xffffffff to silence some overzealous compilers.
174 root 1.204 - use "(libev) " prefix for all libev error messages now.
175 root 1.203
176 root 1.202 4.00 Mon Oct 25 12:32:12 CEST 2010
177 root 1.171 - "PORTING FROM LIBEV 3.X TO 4.X" (in ev.pod) is recommended reading.
178 root 1.161 - ev_embed_stop did not correctly stop the watcher (very good
179     testcase by Vladimir Timofeev).
180 sf-exg 1.191 - ev_run will now always update the current loop time - it erroneously
181 root 1.187 didn't when idle watchers were active, causing timers not to fire.
182 root 1.179 - fix a bug where a timeout of zero caused the timer not to fire
183     in the libevent emulation (testcase by Péter Szabó).
184 root 1.164 - applied win32 fixes by Michael Lenaghan (also James Mansion).
185 root 1.166 - replace EV_MINIMAL by EV_FEATURES.
186 root 1.178 - prefer EPOLL_CTL_ADD over EPOLL_CTL_MOD in some more cases, as it
187     seems the former is *much* faster than the latter.
188 root 1.197 - linux kernel version detection (for inotify bug workarounds)
189     did not work properly.
190 root 1.185 - reduce the number of spurious wake-ups with the ports backend.
191 root 1.158 - remove dependency on sys/queue.h on freebsd (patch by Vanilla Hsu).
192 root 1.186 - do async init within ev_async_start, not ev_async_set, which avoids
193     an API quirk where the set function must be called in the C++ API
194     even when there is nothing to set.
195 root 1.174 - add (undocumented) EV_ENABLE when adding events with kqueue,
196 root 1.175 this might help with OS X, which seems to need it despite documenting
197     not to need it (helpfully pointed out by Tilghman Lesher).
198 root 1.176 - do not use poll by default on freebsd, it's broken (what isn't
199     on freebsd...).
200 root 1.195 - allow to embed epoll on kernels >= 2.6.32.
201 root 1.159 - configure now prepends -O3, not appends it, so one can still
202     override it.
203 root 1.190 - ev.pod: greatly expanded the portability section, added a porting
204     section, a description of watcher states and made lots of minor fixes.
205 root 1.160 - disable poll backend on AIX, the poll header spams the namespace
206     and it's not worth working around dead platforms (reported
207     and analyzed by Aivars Kalvans).
208 root 1.162 - improve header file compatibility of the standalone eventfd code
209     in an obscure case.
210 root 1.163 - implement EV_AVOID_STDIO option.
211     - do not use sscanf to parse linux version number (smaller, faster,
212     no sscanf dependency).
213 root 1.164 - new EV_CHILD_ENABLE and EV_SIGNAL_ENABLE configurable settings.
214 sf-exg 1.172 - update libev.m4 HAVE_CLOCK_SYSCALL test for newer glibcs.
215 root 1.165 - add section on accept() problems to the manpage.
216 root 1.168 - rename EV_TIMEOUT to EV_TIMER.
217 root 1.190 - rename ev_loop_count/depth/verify/loop/unloop.
218 root 1.197 - remove ev_default_destroy and ev_default_fork.
219 root 1.168 - switch to two-digit minor version.
220 root 1.180 - work around an apparent gentoo compiler bug.
221 root 1.181 - define _DARWIN_UNLIMITED_SELECT. just so.
222 root 1.188 - use enum instead of #define for most constants.
223     - improve compatibility to older C++ compilers.
224 root 1.193 - (experimental) ev_run/ev_default_loop/ev_break/ev_loop_new have now
225     default arguments when compiled as C++.
226 root 1.196 - enable automake dependency tracking.
227 root 1.197 - ev_loop_new no longer leaks memory when loop creation failed.
228 root 1.198 - new ev_cleanup watcher type.
229 root 1.157
230 root 1.156 3.9 Thu Dec 31 07:59:59 CET 2009
231 root 1.155 - signalfd is no longer used by default and has to be requested
232     explicitly - this means that easy to catch bugs become hard to
233     catch race conditions, but the users have spoken.
234     - point out the unspecified signal mask in the documentation, and
235     that this is a race condition regardless of EV_SIGNALFD.
236 root 1.142 - backport inotify code to C89.
237 root 1.148 - inotify file descriptors could leak into child processes.
238 sf-exg 1.241 - ev_stat watchers could keep an erroneous extra ref on the loop,
239 root 1.151 preventing exit when unregistering all watchers (testcases
240 root 1.150 provided by ry@tinyclouds.org).
241 root 1.143 - implement EV_WIN32_HANDLE_TO_FD and EV_WIN32_CLOSE_FD configuration
242 root 1.145 symbols to make it easier for apps to do their own fd management.
243 root 1.144 - support EV_IDLE_ENABLE being disabled in ev++.h
244     (patch by Didier Spezia).
245 root 1.147 - take advantage of inotify_init1, if available, to set cloexec/nonblock
246     on fd creation, to avoid races.
247 root 1.150 - the signal handling pipe wasn't always initialised under windows
248     (analysed by lekma).
249 root 1.146 - changed minimum glibc requirement from glibc 2.9 to 2.7, for
250     signalfd.
251 root 1.152 - add missing string.h include (Denis F. Latypoff).
252 root 1.153 - only replace ev_stat.prev when we detect an actual difference,
253     so prev is (almost) always different to attr. this might
254 sf-exg 1.191 have caused the problems with 04_stat.t.
255 root 1.154 - add ev::timer->remaining () method to C++ API.
256 root 1.142
257 root 1.141 3.8 Sun Aug 9 14:30:45 CEST 2009
258 root 1.133 - incompatible change: do not necessarily reset signal handler
259     to SIG_DFL when a sighandler is stopped.
260 root 1.135 - ev_default_destroy did not properly free or zero some members,
261 sf-exg 1.191 potentially causing crashes and memory corruption on repeated
262 root 1.134 ev_default_destroy/ev_default_loop calls.
263 root 1.133 - take advantage of signalfd on GNU/Linux systems.
264     - document that the signal mask might be in an unspecified
265     state when using libev's signal handling.
266 root 1.136 - take advantage of some GNU/Linux calls to set cloexec/nonblock
267     on fd creation, to avoid race conditions.
268 root 1.132
269 root 1.131 3.7 Fri Jul 17 16:36:32 CEST 2009
270 root 1.128 - ev_unloop and ev_loop wrongly used a global variable to exit loops,
271     instead of using a per-loop variable (bug caught by accident...).
272     - the ev_set_io_collect_interval interpretation has changed.
273     - add new functionality: ev_set_userdata, ev_userdata,
274 root 1.126 ev_set_invoke_pending_cb, ev_set_loop_release_cb,
275 root 1.132 ev_invoke_pending, ev_pending_count, together with a long example
276     about thread locking.
277 root 1.128 - add ev_timer_remaining (as requested by Denis F. Latypoff).
278     - add ev_loop_depth.
279 root 1.124 - calling ev_unloop in fork/prepare watchers will no longer poll
280     for new events.
281 root 1.115 - Denis F. Latypoff corrected many typos in example code snippets.
282     - honor autoconf detection of EV_USE_CLOCK_SYSCALL, also double-
283     check that the syscall number is available before trying to
284     use it (reported by ry@tinyclouds).
285 root 1.117 - use GetSystemTimeAsFileTime instead of _timeb on windows, for
286 root 1.116 slightly higher accuracy.
287 root 1.122 - properly declare ev_loop_verify and ev_now_update even when
288     !EV_MULTIPLICITY.
289 root 1.121 - do not compile in any priority code when EV_MAXPRI == EV_MINPRI.
290 root 1.123 - support EV_MINIMAL==2 for a reduced API.
291 root 1.125 - actually 0-initialise struct sigaction when installing signals.
292 root 1.127 - add section on hibernate and stopped processes to ev_timer docs.
293 root 1.115
294 root 1.113 3.6 Tue Apr 28 02:49:30 CEST 2009
295 root 1.107 - multiple timers becoming ready within an event loop iteration
296     will be invoked in the "correct" order now.
297 root 1.105 - do not leave the event loop early just because we have no active
298     watchers, fixing a problem when embedding a kqueue loop
299     that has active kernel events but no registered watchers
300     (reported by blacksand blacksand).
301 root 1.102 - correctly zero the idx values for arrays, so destroying and
302     reinitialising the default loop actually works (patch by
303     Malek Hadj-Ali).
304 root 1.108 - implement ev_suspend and ev_resume.
305 root 1.106 - new EV_CUSTOM revents flag for use by applications.
306 sf-exg 1.241 - add documentation section about priorities.
307 sf-exg 1.286 - add a glossary to the documentation.
308 root 1.111 - extend the ev_fork description slightly.
309 root 1.112 - optimize a jump out of call_pending.
310 root 1.102
311 root 1.101 3.53 Sun Feb 15 02:38:20 CET 2009
312     - fix a bug in event pipe creation on win32 that would cause a
313     failed assertion on event loop creation (patch by Malek Hadj-Ali).
314 root 1.100 - probe for CLOCK_REALTIME support at runtime as well and fall
315     back to gettimeofday if there is an error, to support older
316     operating systems with newer header files/libraries.
317     - prefer gettimeofday over clock_gettime with USE_CLOCK_SYSCALL
318     (default most everywhere), otherwise not.
319    
320 root 1.99 3.52 Wed Jan 7 21:43:02 CET 2009
321 root 1.97 - fix compilation of select backend in fd_set mode when NFDBITS is
322     missing (to get it to compile on QNX, reported by Rodrigo Campos).
323     - better select-nfds handling when select backend is in fd_set mode.
324     - diagnose fd_set overruns when select backend is in fd_set mode.
325     - due to a thinko, instead of disabling everything but
326     select on the borked OS X platform, everything but select was
327     allowed (reported by Emanuele Giaquinta).
328 root 1.95 - actually verify that local and remote port are matching in
329     libev's socketpair emulation, which makes denial-of-service
330     attacks harder (but not impossible - it's windows). Make sure
331 root 1.96 it even works under vista, which thinks that getpeer/sockname
332     should return fantasy port numbers.
333 root 1.100 - include "libev" in all assertion messages for potentially
334 root 1.97 clearer diagnostics.
335 root 1.98 - event_get_version (libevent compatibility) returned
336     a useless string instead of the expected version string
337     (patch by W.C.A. Wijngaards).
338 root 1.95
339 root 1.94 3.51 Wed Dec 24 23:00:11 CET 2008
340 root 1.91 - fix a bug where an inotify watcher was added twice, causing
341 root 1.92 freezes on hash collisions (reported and analysed by Graham Leggett).
342 root 1.87 - new config symbol, EV_USE_CLOCK_SYSCALL, to make libev use
343     a direct syscall - slower, but no dependency on librt et al.
344 root 1.88 - assume negative return values != -1 signals success of port_getn
345     (http://cvs.epicsol.org/cgi/viewcvs.cgi/epic5/source/newio.c?rev=1.52)
346     (no known failure reports, but it doesn't hurt).
347 root 1.93 - fork detection in ev_embed now stops and restarts the watcher
348     automatically.
349 root 1.89 - EXPERIMENTAL: default the method to operator () in ev++.h,
350     to make it nicer to use functors (requested by Benedek László).
351     - fixed const object callbacks in ev++.h.
352 root 1.90 - replaced loop_ref argument of watcher.set (loop) by a direct
353     ev_loop * in ev++.h, to avoid clashes with functor patch.
354 root 1.91 - do not try to watch the empty string via inotify.
355 root 1.92 - inotify watchers could be leaked under certain circumstances.
356     - OS X 10.5 is actually even more broken than earlier versions,
357     so fall back to select on that piece of garbage.
358 root 1.93 - fixed some weirdness in the ev_embed documentation.
359 root 1.87
360 root 1.86 3.49 Wed Nov 19 11:26:53 CET 2008
361 root 1.83 - ev_stat watchers will now use inotify as a mere hint on
362     kernels <2.6.25, or if the filesystem is not in the
363     "known to be good" list.
364 root 1.84 - better mingw32 compatibility (it's not as borked as native win32)
365     (analysed by Roger Pack).
366 root 1.85 - include stdio.h in the example program, as too many people are
367     confused by the weird C language otherwise. I guess the next thing
368     I get told is that the "..." ellipses in the examples don't compile
369     with their C compiler.
370 root 1.83
371 root 1.80 3.48 Thu Oct 30 09:02:37 CET 2008
372 root 1.71 - further optimise away the EPOLL_CTL_ADD/MOD combo in the epoll
373     backend by assuming the kernel event mask hasn't changed if
374     ADD fails with EEXIST.
375 root 1.75 - work around spurious event notification bugs in epoll by using
376 root 1.77 a 32-bit generation counter. recreate kernel state if we receive
377 root 1.78 spurious notifications or unwanted events. this is very costly,
378     but I didn't come up with this horrible design.
379 root 1.71 - use memset to initialise most arrays now and do away with the
380     init functions.
381 root 1.72 - expand time-out strategies into a "Be smart about timeouts" section.
382     - drop the "struct" from all ev_watcher declarations in the
383 root 1.73 documentation and did other clarifications (yeah, it was a mistake
384     to have a struct AND a function called ev_loop).
385 root 1.74 - fix a bug where ev_default would not initialise the default
386     loop again after it was destroyed with ev_default_destroy.
387 root 1.79 - rename syserr to ev_syserr to avoid name clashes when embedding,
388     do similar changes for event.c.
389 root 1.71
390 root 1.69 3.45 Tue Oct 21 21:59:26 CEST 2008
391 root 1.67 - disable inotify usage on linux <2.6.25, as it is broken
392     (reported by Yoann Vandoorselaere).
393 sf-exg 1.191 - ev_stat erroneously would try to add inotify watchers
394 root 1.68 even when inotify wasn't available (this should only
395 root 1.67 have a performance impact).
396 root 1.65 - ev_once now passes both timeout and io to the callback if both
397     occur concurrently, instead of giving timeouts precedence.
398 root 1.66 - disable EV_USE_INOTIFY when sys/inotify.h is too old.
399 root 1.65
400 root 1.62 3.44 Mon Sep 29 05:18:39 CEST 2008
401     - embed watchers now automatically invoke ev_loop_fork on the
402     embedded loop when the parent loop forks.
403 root 1.58 - new function: ev_now_update (loop).
404 root 1.57 - verify_watcher was not marked static.
405 root 1.59 - improve the "associating..." manpage section.
406 root 1.60 - documentation tweaks here and there.
407 root 1.57
408 root 1.56 3.43 Sun Jul 6 05:34:41 CEST 2008
409 root 1.54 - include more include files on windows to get struct _stati64
410 root 1.56 (reported by Chris Hulbert, but doesn't quite fix his issue).
411 root 1.53 - add missing #include <io.h> in ev.c on windows (reported by
412     Matt Tolton).
413    
414 root 1.52 3.42 Tue Jun 17 12:12:07 CEST 2008
415 root 1.50 - work around yet another windows bug: FD_SET actually adds fd's
416     multiple times to the fd_*SET*, despite official MSN docs claiming
417 root 1.51 otherwise. Reported and well-analysed by Matt Tolton.
418     - define NFDBITS to 0 when EV_SELECT_IS_WINSOCKET to make it compile
419 root 1.48 (reported any analysed by Chris Hulbert).
420 root 1.49 - fix a bug in ev_ebadf (this function is only used to catch
421     programming errors in the libev user). reported by Matt Tolton.
422     - fix a bug in fd_intern on win32 (could lead to compile errors
423     under some circumstances, but would work correctly if it compiles).
424     reported by Matt Tolton.
425 root 1.50 - (try to) work around missing lstat on windows.
426 root 1.45 - pass in the write fd set as except fd set under windows. windows
427 root 1.46 is so uncontrollably lame that it requires this. this means that
428     switching off oobinline is not supported (but tcp/ip doesn't
429     have oob, so that would be stupid anyways.
430 root 1.47 - use posix module symbol to auto-detect monotonic clock presence
431     and some other default values.
432 root 1.45
433 root 1.44 3.41 Fri May 23 18:42:54 CEST 2008
434 root 1.46 - work around an obscure bug in winsocket select: if you
435 root 1.40 provide only empty fd sets then select returns WSAEINVAL. how sucky.
436 root 1.41 - improve timer scheduling stability and reduce use of time_epsilon.
437 root 1.36 - use 1-based 2-heap for EV_MINIMAL, simplifies code, reduces
438     codesize and makes for better cache-efficiency.
439     - use 3-based 4-heap for !EV_MINIMAL. this makes better use
440     of cpu cache lines and gives better growth behaviour than
441     2-based heaps.
442 root 1.38 - cache timestamp within heap for !EV_MINIMAL, to avoid random
443     memory accesses.
444     - document/add EV_USE_4HEAP and EV_HEAP_CACHE_AT.
445 root 1.33 - fix a potential aliasing issue in ev_timer_again.
446 root 1.35 - add/document ev_periodic_at, retract direct access to ->at.
447     - improve ev_stat docs.
448     - add portability requirements section.
449 root 1.39 - fix manpage headers etc.
450 root 1.40 - normalise WSA error codes to lower range on windows.
451 root 1.43 - add consistency check code that can be called automatically
452     or on demand to check for internal structures (ev_loop_verify).
453 root 1.31
454 root 1.30 3.31 Wed Apr 16 20:45:04 CEST 2008
455     - added last minute fix for ev_poll.c by Brandon Black.
456 root 1.29
457 root 1.28 3.3 Wed Apr 16 19:04:10 CEST 2008
458 root 1.23 - event_base_loopexit should return 0 on success
459     (W.C.A. Wijngaards).
460 root 1.20 - added linux eventfd support.
461     - try to autodetect epoll and inotify support
462     by libc header version if not using autoconf.
463 root 1.21 - new symbols: EV_DEFAULT_UC and EV_DEFAULT_UC_.
464     - declare functions defined in ev.h as inline if
465     C99 or gcc are available.
466     - enable inlining with gcc versions 2 and 3.
467 root 1.25 - work around broken poll implementations potentially
468     not clearing revents field in ev_poll (Brandon Black)
469     (no such systems are known at this time).
470 root 1.23 - work around a bug in realloc on openbsd and darwin,
471 sf-exg 1.191 also makes the erroneous valgrind complaints
472 root 1.23 go away (noted by various people).
473 root 1.26 - fix ev_async_pending, add c++ wrapper for ev_async
474 sf-exg 1.191 (based on patch sent by Johannes Deisenhofer).
475 root 1.26 - add sensible set method to ev::embed.
476 root 1.27 - made integer constants type int in ev.h.
477 root 1.20
478 root 1.19 3.2 Wed Apr 2 17:11:19 CEST 2008
479 root 1.15 - fix a 64 bit overflow issue in the select backend,
480     by using fd_mask instead of int for the mask.
481 root 1.16 - rename internal sighandler to avoid clash with very old perls.
482 root 1.18 - entering ev_loop will not clear the ONESHOT or NONBLOCKING
483     flags of any outer loops anymore.
484 root 1.17 - add ev_async_pending.
485 root 1.15
486 root 1.14 3.1 Thu Mar 13 13:45:22 CET 2008
487 root 1.12 - implement ev_async watchers.
488 root 1.10 - only initialise signal pipe on demand.
489     - make use of sig_atomic_t configurable.
490 root 1.14 - improved documentation.
491 root 1.10
492 root 1.9 3.0 Mon Jan 28 13:14:47 CET 2008
493 root 1.6 - API/ABI bump to version 3.0.
494 root 1.4 - ev++.h includes "ev.h" by default now, not <ev.h>.
495     - slightly improved documentation.
496 root 1.5 - speed up signal detection after a fork.
497 root 1.6 - only optionally return trace status changed in ev_child
498     watchers.

504     - remove event_compat.h from the libev tarball.
505     - change how include files are found.
506     - doc updates.
507     - update licenses, explicitly allow for GPL relicensing.
508    
509     2.0 Sat Dec 22 17:47:03 CET 2007
