Revision history for libev, a high-performance and full-featured event loop. |
| 2 |
|
| 3 |
WISH? monotonic clocks times/GetTickCount for coarse corrections? |
| 4 |
|
| 5 |
- further optimise away the EPOLL_CTL_ADD/MOD combo in the epoll |
| 6 |
backend by assuming the kernel event mask hasn't changed if |
| 7 |
ADD fails with EEXIST. |
| 8 |
- work around spurious event notification bugs in epoll by using |
| 9 |
a 32-bit generation counter. recreate kernel state if we receive |
| 10 |
spurious notifications or unwanted events. |
| 11 |
- use memset to initialise most arrays now and do away with the |
| 12 |
init functions. |
| 13 |
- expand time-out strategies into a "Be smart about timeouts" section. |
| 14 |
- drop the "struct" from all ev_watcher declarations in the |
| 15 |
documentation and did other clarifications (yeah, it was a mistake |
| 16 |
to have a struct AND a function called ev_loop). |
| 17 |
- fix a bug where ev_default would not initialise the default |
| 18 |
loop again after it was destroyed with ev_default_destroy. |
| 19 |
- rename syserr to ev_syserr to avoid name clashes when embedding. |
| 20 |
|
| 21 |
3.45 Tue Oct 21 21:59:26 CEST 2008 |
| 22 |
- disable inotify usage on linux <2.6.25, as it is broken |
| 23 |
(reported by Yoann Vandoorselaere). |
| 24 |
- ev_stat errornously would try to add inotify watchers |
| 25 |
even when inotify wasn't available (this should only |
| 26 |
have a performance impact). |
| 27 |
- ev_once now passes both timeout and io to the callback if both |
| 28 |
occur concurrently, instead of giving timeouts precedence. |
| 29 |
- disable EV_USE_INOTIFY when sys/inotify.h is too old. |
| 30 |
|
| 31 |
3.44 Mon Sep 29 05:18:39 CEST 2008 |
| 32 |
- embed watchers now automatically invoke ev_loop_fork on the |
| 33 |
embedded loop when the parent loop forks. |
| 34 |
- new function: ev_now_update (loop). |
| 35 |
- verify_watcher was not marked static. |
| 36 |
- improve the "associating..." manpage section. |
| 37 |
- documentation tweaks here and there. |
| 38 |
|
| 39 |
3.43 Sun Jul 6 05:34:41 CEST 2008 |
| 40 |
- include more include files on windows to get struct _stati64 |
| 41 |
(reported by Chris Hulbert, but doesn't quite fix his issue). |
| 42 |
- add missing #include <io.h> in ev.c on windows (reported by |
| 43 |
Matt Tolton). |
| 44 |
|
| 45 |
3.42 Tue Jun 17 12:12:07 CEST 2008 |
| 46 |
- work around yet another windows bug: FD_SET actually adds fd's |
| 47 |
multiple times to the fd_*SET*, despite official MSN docs claiming |
| 48 |
otherwise. Reported and well-analysed by Matt Tolton. |
| 49 |
- define NFDBITS to 0 when EV_SELECT_IS_WINSOCKET to make it compile |
| 50 |
(reported any analysed by Chris Hulbert). |
| 51 |
- fix a bug in ev_ebadf (this function is only used to catch |
| 52 |
programming errors in the libev user). reported by Matt Tolton. |
| 53 |
- fix a bug in fd_intern on win32 (could lead to compile errors |
| 54 |
under some circumstances, but would work correctly if it compiles). |
| 55 |
reported by Matt Tolton. |
| 56 |
- (try to) work around missing lstat on windows. |
| 57 |
- pass in the write fd set as except fd set under windows. windows |
| 58 |
is so uncontrollably lame that it requires this. this means that |
| 59 |
switching off oobinline is not supported (but tcp/ip doesn't |
| 60 |
have oob, so that would be stupid anyways. |
| 61 |
- use posix module symbol to auto-detect monotonic clock presence |
| 62 |
and some other default values. |
| 63 |
|
| 64 |
3.41 Fri May 23 18:42:54 CEST 2008 |
| 65 |
- work around an obscure bug in winsocket select: if you |
| 66 |
provide only empty fd sets then select returns WSAEINVAL. how sucky. |
| 67 |
- improve timer scheduling stability and reduce use of time_epsilon. |
| 68 |
- use 1-based 2-heap for EV_MINIMAL, simplifies code, reduces |
| 69 |
codesize and makes for better cache-efficiency. |
| 70 |
- use 3-based 4-heap for !EV_MINIMAL. this makes better use |
| 71 |
of cpu cache lines and gives better growth behaviour than |
| 72 |
2-based heaps. |
| 73 |
- cache timestamp within heap for !EV_MINIMAL, to avoid random |
| 74 |
memory accesses. |
| 75 |
- document/add EV_USE_4HEAP and EV_HEAP_CACHE_AT. |
| 76 |
- fix a potential aliasing issue in ev_timer_again. |
| 77 |
- add/document ev_periodic_at, retract direct access to ->at. |
| 78 |
- improve ev_stat docs. |
| 79 |
- add portability requirements section. |
| 80 |
- fix manpage headers etc. |
| 81 |
- normalise WSA error codes to lower range on windows. |
| 82 |
- add consistency check code that can be called automatically |
| 83 |
or on demand to check for internal structures (ev_loop_verify). |
| 84 |
|
| 85 |
3.31 Wed Apr 16 20:45:04 CEST 2008 |
| 86 |
- added last minute fix for ev_poll.c by Brandon Black. |
| 87 |
|
| 88 |
3.3 Wed Apr 16 19:04:10 CEST 2008 |
| 89 |
- event_base_loopexit should return 0 on success |
| 90 |
(W.C.A. Wijngaards). |
| 91 |
- added linux eventfd support. |
| 92 |
- try to autodetect epoll and inotify support |
| 93 |
by libc header version if not using autoconf. |
| 94 |
- new symbols: EV_DEFAULT_UC and EV_DEFAULT_UC_. |
| 95 |
- declare functions defined in ev.h as inline if |
| 96 |
C99 or gcc are available. |
| 97 |
- enable inlining with gcc versions 2 and 3. |
| 98 |
- work around broken poll implementations potentially |
| 99 |
not clearing revents field in ev_poll (Brandon Black) |
| 100 |
(no such systems are known at this time). |
| 101 |
- work around a bug in realloc on openbsd and darwin, |
| 102 |
also makes the errornous valgrind complaints |
| 103 |
go away (noted by various people). |
| 104 |
- fix ev_async_pending, add c++ wrapper for ev_async |
| 105 |
(based on patch sent by Johannes Deisenhofer. |
| 106 |
- add sensible set method to ev::embed. |
| 107 |
- made integer constants type int in ev.h. |
| 108 |
|
| 109 |
3.2 Wed Apr 2 17:11:19 CEST 2008 |
| 110 |
- fix a 64 bit overflow issue in the select backend, |
| 111 |
by using fd_mask instead of int for the mask. |
| 112 |
- rename internal sighandler to avoid clash with very old perls. |
| 113 |
- entering ev_loop will not clear the ONESHOT or NONBLOCKING |
| 114 |
flags of any outer loops anymore. |
| 115 |
- add ev_async_pending. |
| 116 |
|
| 117 |
