|
|
16 | - destroying a non-default loop would stop the global waitpid |
|
|
17 | watcher (Denis Bilenko). |
|
|
18 | - queueing pending watchers of higher priority from a watcher now invokes |
|
|
19 | them in a timely fashion (reported by Denis Bilenko). |
|
|
20 | - add throw() to all libev functions that cannot throw exceptions, for |
|
|
21 | further code size decrease when compiling for C++. |
|
|
22 | - add throw () to callbacks that must not throw exceptions (allocator, |
|
|
23 | syserr, loop acquire/release, periodic reschedule cbs). |
|
|
24 | - fix event_base_loop return code, add event_get_callback, event_base_new, |
|
|
25 | event_base_get_method calls to improve libevent 1.x emulation and add |
|
|
26 | some libevent 2.x functionality (based on a patch by Jeff Davey). |
|
|
27 | - add more memory fences to fix a bug reported by Jeff Davey. Better |
|
|
28 | be overfenced than underprotected. |
|
|
29 | - ev_run now returns a boolean status (true meaning watchers are |
|
|
30 | still active). |
|
|
31 | - ev_once: undef EV_ERROR in ev_kqueue.c, to avoid clashing with |
|
|
32 | libev's EV_ERROR (reported by 191919). |
|
|
33 | - (ecb) add memory fence support for xlC (Darin McBride). |
|
|
34 | - (ecb) add memory fence support for gcc-mips (Anton Kirilov). |
|
|
35 | - (ecb) add memory fence support for gcc-alpha (Christian Weisgerber). |
|
|
36 | - work around some kernels losing file descriptors by leaking |
|
|
37 | the kqueue descriptor in the child. |
|
|
38 | - include sys/syscall.h instead of plain syscall.h. |
|
|
39 | - check for io watcher loops in ev_verify, check for the most |
|
|
40 | common reported usage bug in ev_io_start. |
|
|
41 | - chose socket vs. WSASocket at compiletime using EV_USE_WSASOCKET. |
|
|
42 | - always use WSASend/WSARecv directly on windows, hoping that this |
|
|
43 | works in all cases (unlike read/write/send/recv...). |
|
|
44 | - try to detect signals around a fork faster (test program by |
|
|
45 | Denis Bilenko). |
|
|
46 | - work around recent glibc versions that leak memory in realloc. |
|
|
47 | - rename ev::embed::set to ev::embed::set_embed to avoid clashing |
|
|
48 | the watcher base set (loop) method. |
|
|
49 | - rewrite the async/signal pipe logic to always keep a valid fd, which |
|
|
50 | simplifies (and hopefuly correctifies :) the race checking |
|
|
51 | on fork, at the cost of one extra fd. |
|
|
52 | |
|
|
53 | 4.11 Sat Feb 4 19:52:39 CET 2012 |
|
|
54 | - INCOMPATIBLE CHANGE: ev_timer_again now clears the pending status, as |
|
|
55 | was documented already, but not implemented in the repeating case. |
|
|
56 | - new compiletime symbols: EV_NO_SMP and EV_NO_THREADS. |
|
|
57 | - fix a race where the workaround against the epoll fork bugs |
|
|
58 | caused signals to not be handled anymore. |
|
|
59 | - correct backend_fudge for most backends, and implement a windows |
|
|
60 | specific workaround to avoid looping because we call both |
|
|
61 | select and Sleep, both with different time resolutions. |
|
|
62 | - document range and guarantees of ev_sleep. |
|
|
63 | - document reasonable ranges for periodics interval and offset. |
|
|
64 | - rename backend_fudge to backend_mintime to avoid future confusion :) |
|
|
65 | - change the default periodic reschedule function to hopefully be more |
|
|
66 | exact and correct even in corner cases or in the far future. |
|
|
67 | - do not rely on -lm anymore: use it when available but use our |
|
|
68 | own floor () if it is missing. This should make it easier to embed, |
|
|
69 | as no external libraries are required. |
|
|
70 | - strategically import macros from libecb and mark rarely-used functions |
|
|
71 | as cache-cold (saving almost 2k code size on typical amd64 setups). |
|
|
72 | - add Symbols.ev and Symbols.event files, that were missing. |
|
|
73 | - fix backend_mintime value for epoll (was 1/1024, is 1/1000 now). |
|
|
74 | - fix #3 "be smart about timeouts" to not "deadlock" when |
|
|
75 | timeout == now, also improve the section overall. |
|
|
76 | - avoid "AVOIDING FINISHING BEFORE RETURNING" idiom. |
|
|
77 | - support new EV_API_STATIC mode to make all libev symbols |
|
|
78 | static. |
|
|
79 | - supply default CFLAGS of -g -O3 with gcc when original CFLAGS |
|
|
80 | were empty. |
|
|
81 | |
|
|
82 | 4.04 Wed Feb 16 09:01:51 CET 2011 |
|
|
83 | - fix two problems in the native win32 backend, where reuse of fd's |
|
|
84 | with different underlying handles caused handles not to be removed |
|
|
85 | or added to the select set (analyzed and tested by Bert Belder). |
|
|
86 | - do no rely on ceil() in ev_e?poll.c. |
|
|
87 | - backport libev to HP-UX versions before 11 v3. |
|
|
88 | - configure did not detect nanosleep and clock_gettime properly when |
|
|
89 | they are available in the libc (as opposed to -lrt). |
|
|
90 | |
|
|
91 | 4.03 Tue Jan 11 14:37:25 CET 2011 |
|
|
92 | - officially support polling files with all backends. |
|
|
93 | - support files, /dev/zero etc. the same way as select in the epoll |
|
|
94 | backend, by generating events on our own. |
|
|
95 | - ports backend: work around solaris bug 6874410 and many related ones |
|
|
96 | (EINTR, maybe more), with no performance loss (note that the solaris |
|
|
97 | bug report is actually wrong, reality is far more bizarre and broken |
|
|
98 | than that). |
|
|
99 | - define EV_READ/EV_WRITE as macros in event.h, as some programs use |
|
|
100 | #ifdef to test for them. |
|
|
101 | - new (experimental) function: ev_feed_signal. |
|
|
102 | - new (to become default) EVFLAG_NOSIGMASK flag. |
|
|
103 | - new EVBACKEND_MASK symbol. |
|
|
104 | - updated COMMON IDIOMS SECTION. |
