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

346 root 1.68 even when inotify wasn't available (this should only

367 root 1.50 - work around yet another windows bug: FD_SET actually adds fd's

386 root 1.46 - work around an obscure bug in winsocket select: if you
387 root 1.40 provide only empty fd sets then select returns WSAEINVAL. how sucky.
388 root 1.41 - improve timer scheduling stability and reduce use of time_epsilon.
389 root 1.36 - use 1-based 2-heap for EV_MINIMAL, simplifies code, reduces
390     codesize and makes for better cache-efficiency.
391     - use 3-based 4-heap for !EV_MINIMAL. this makes better use
392     of cpu cache lines and gives better growth behaviour than
