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

454 |
- make use of sig_atomic_t configurable. |
455 |
- improved documentation. |
456 |
|
457 |
3.0 Mon Jan 28 13:14:47 CET 2008 |
458 |
- API/ABI bump to version 3.0. |
459 |
- ev++.h includes "ev.h" by default now, not <ev.h>. |
460 |
- slightly improved documentation. |
461 |
- speed up signal detection after a fork. |
462 |
- only optionally return trace status changed in ev_child |
463 |
watchers. |
464 |
- experimental (and undocumented) loop wrappers for ev++.h. |
465 |
|
