|
| 6 |
3.9 Thu Dec 31 07:59:59 CET 2009 |
| 7 |
- disable t/07* under automatic testing. |
| 8 |
- increase t/09* timeouts as netbsd has *horribly* broken |
| 9 |
select/kevent that *usually* sleep >>0.6s instead of 0.3. |
| 10 |
- add constants EV::FLAG_NOSIGFD, EV::FLAG_NOINOTIFY and |
| 11 |
EV::BACKEND_ALL. |
| 12 |
- (libev) signalfd is no longer used by default. |
| 13 |
- (libev) backport inotify code to C89. |
| 14 |
- (libev) inotify file descriptors could leak into child processes. |
| 15 |
- (libev) ev_stat watchers could keep an errornous extra ref on the loop. |
| 16 |
- (libev) take advantage of inotify_init1, if available. |
| 17 |
- (libev) the signal handling pipe wasn't always initialised under windows. |
| 18 |
- changed minimum glibc requirement from glibc 2.9 to 2.7, for signalfd. |
| 19 |
- (libev) only replace ev_stat.prev when we detect an actual difference. |
| 20 |
|
| 21 |
3.8 Sun Aug 9 15:30:10 CEST 2009 |
| 22 |
- implement $loop->signal/signal_ns. |
| 23 |
- (libev) incompatible change: do not necessarily reset signal |
| 24 |
handler to SIG_DFL when a sighandler is stopped. |
| 25 |
- (libev) ev_default_destroy did not properly free or zero some |
| 26 |
members, potentially causing crashes and memory corruption on |
| 27 |
repated ev_default_destroy/ev_default_loop calls. |
| 28 |
- (libev) take advantage of signalfd on GNU/Linux systems. |
| 29 |
- (libev) document that the signal mask might be in an unspecified |
| 30 |
state when using libev's signal handling. |
| 31 |
- (libev) take advantage of some GNU/Linux calls to set |
| 32 |
cloexec/nonblock on fd creation, to avoid race conditions. |
| 33 |
- implement internal glue code to interface more efficiently |
| 34 |
with AnyEvent. |
| 35 |
|
| 36 |
3.7 Fri Jul 17 16:49:16 CEST 2009 |
| 37 |
- add EV::loop_verify and EV::loop_depth. |
| 38 |
- use output filehandle for i/o watchers waiting |
| 39 |
for EV_WRITE, otherwise input filehandle. |
| 40 |
- use common schmorp.h header. |
| 41 |
- add EV::Timer->remaining. |
| 42 |
- allow for subclassing of EV::Loop (see the exciting |
| 43 |
EV::Loop::Async module for an example). |
| 44 |
- added EV::invoke_pending and EV::pending_count. |
| 45 |
|
| 46 |
- (libev) ev_unloop and ev_loop wrongly used a global variable to |
| 47 |
exit loops, instead of using a per-loop variable. |
| 48 |
- (libev) the ev_set_io_collect_interval interpretation has changed. |
| 49 |
- add new functionality: EV::invoke_pending, EV::pending_count. |
| 50 |
- add $timer->remaining. |
| 51 |
- add EV::loop_depth. |
| 52 |
- (libev) calling unloop in fork/prepare watchers will no longer poll |
| 53 |
for new events. |
| 54 |
- (libev) use GetSystemTimeAsFileTime instead of _timeb on windows, |
| 55 |
for slightly higher accuracy. |
| 56 |
- (libev) actually 0-initialise struct sigaction when installing |
| 57 |
signals. |
| 58 |
|
| 59 |
3.6 Tue Apr 28 02:50:37 CEST 2009 |
| 60 |
- keepalive(0) could decrease the refcount of the loop |
| 61 |
permanently. |
| 62 |
- add ev_suspend/ev_resume, also make ev_now_update |
| 63 |
accessible via the XS API. |
| 64 |
- most EV::<eventtype> constants were missing and have been |
| 65 |
added :/. |
| 66 |
- add EV::VERSION_MAJOR/VERSION_MINOR constants. |
| 67 |
- (libev) multiple timers becoming ready within an event loop |
| 68 |
iteration will be invoked in the "correct" order now. |
| 69 |
- (libev) do not leave the event loop early just because we have |
| 70 |
no active watchers, fixing a problem when embedding a kqueue |
| 71 |
loop that has active kernel events but no registered watchers |
| 72 |
(reported by blacksand blacksand). |
| 73 |
- (libev) correctly zero the idx values for arrays, so destroying |
| 74 |
and reinitialising the default loop actually works (patch by |
| 75 |
Malek Hadj-Ali). |
| 76 |
- (libev) new EV::CUSTOM revents flag for use by applications. |
| 77 |
- (libev) add documentation section about priorites. |
| 78 |
- (libev) add a glossary to the dcoumentation. |
| 79 |
- (libev) extend the ev_fork description slightly. |
| 80 |
- (libev) optimize a jump out of call_pending. |
| 81 |
- t/03_keepalive could fail when there was no actual error. |
| 82 |
|
| 83 |
3.53 Sun Feb 15 02:38:20 CET 2009 |
| 84 |
- (libev) on win32, the event loop creation could randomly fail |
| 85 |
due to an initialised variable having the wrong value. |
| 86 |
- (libev) probe for CLOCK_REALTIME support at runtime as well and |
| 87 |
fall back to gettimeofday if there is an error, to support older |
| 88 |
operating systems with newer header files/libraries. |
| 89 |
- prefer gettimeofday over clock_gettime by default. |
| 90 |
|
| 91 |
3.52 Wed Jan 7 21:46:14 CET 2009 |
| 92 |
- (libev) fix some issues in the select backend when in fd_set mode. |
| 93 |
- (libev) due to a thinko, instead of disabling everything but |
| 94 |
select on the borked OS X platform, everything but select was |
| 95 |
allowed (reported by Emanuele Giaquinta). |
| 96 |
- (libev) actually verify that local and remote port are matching in |
| 97 |
libev's socketpair emulation, which makes denial-of-service |
| 98 |
attacks harder (but not impossible - it's windows). Make sure |
| 99 |
it even works under vista, which thinks that getpeer/sockname |
| 100 |
should return fantasy port numbers. |
| 101 |
|
| 102 |
3.51 Wed Dec 24 23:01:59 CET 2008 |
| 103 |
- do not cache the arguments passed to callbacks if the refcount |
| 104 |
indicates that the callback has stolen them. |
| 105 |
- (libev) try to avoid librt on GNU/Linux. |
| 106 |
- (libev) check port_getn return value dfferently, might potentially |
| 107 |
avoid problems. |
| 108 |
- (libev) fix a bug with stat watchers possibly causing freezes. |
| 109 |
- (libev) work around OS X 10.5 breaking poll, now select is the |
| 110 |
only viable choice left on that pile of garbage. |
| 111 |
- play tester whore: disable some tests that typically fail only |
| 112 |
on cpan tester machines. |
| 113 |
|
| 114 |
3.49 Wed Nov 19 11:26:53 CET 2008 |
| 115 |
- fix typos in manpage (Alex Efros). |
| 116 |
- increase timing even further, for the ever-overloaded cpan-tester |
| 117 |
machines, and to the detriment of everybody else who wants a fast |
| 118 |
make test. |
| 119 |
- possible 5.6 compatibility. |
| 120 |
- (libev) use inotify even on buggy kernels, but don't rely on it. |
| 121 |
- (libev) use inotify only as an added hint on network filesystems. |
| 122 |
|
| 123 |
3.48 Thu Oct 30 09:09:48 CET 2008 |
| 124 |
- (libev) use a generation counter to detect spurious epoll events |
| 125 |
and recreate the kernel in such a case (sorry, it's slow, but |
| 126 |
I didn't design epoll...). |
| 127 |
- (libev) optimise away an EPOLL_CTL_ADD/MOD combo in the epoll |
| 128 |
backend in some cases. |
| 129 |
- (libev) use memset to initialise most arrays now and do away |
| 130 |
with the init functions. |
| 131 |
- speed up event callback invocation further (~15%), by |
| 132 |
not creating the object reference each time. |
| 133 |
- EV::sleep was documented, but not implemented. fun. |
| 134 |
|
| 135 |
3.45 Tue Oct 21 22:20:39 CEST 2008 |
| 136 |
- (libev) disable inotify usage on linux <2.6.25 (kernel bug). |
| 137 |
- (libev) ev_embed will now automatically follow fork. |
| 138 |
- (libev) ev_once will now pass both io and timeout events to |
| 139 |
the callback when both happen concurrently, instead of giving |
| 140 |
one precedence. |
| 141 |
- install C library documentation as EV::libev manpage (sorry, oesi). |
| 142 |
- (libev) fix a minor performance bug in ev_stat handling. |
| 143 |
|
| 144 |
3.44 Mon Sep 29 05:16:31 CEST 2008 |

| 148 |
- made the EV::embed callback optional again. reported by |
| 149 |
Vladimir Timofeev. |
| 150 |
|
| 151 |
3.43 Tue Jul 8 20:56:31 CEST 2008 |
| 152 |
- disabled warnings in EV.pm, the CHECK issue is now understood |
| 153 |
and harmless. |
| 154 |
|
| 155 |
3.42 Mon May 26 07:36:46 CEST 2008 |
| 156 |
- (libev) work around another bug in windows perls and |
| 157 |
windows itself: failed connects do NOT set read or write |
| 158 |
flags in select, but this version of libev will. |
| 159 |
|
| 160 |
3.41 Thu May 22 01:39:40 CEST 2008 |

| 164 |
- clarify documentation for periodic reschedule callbacks. |
| 165 |
- verify that the passed callback argument is indeed a code |
| 166 |
reference, for earlier error reporting and a nice calling |

|
| 169 |
3.4 Tue May 20 21:51:55 CEST 2008 |
| 170 |
- (libev) work around both a windows bug and a bug in perl's |
| 171 |
select on windows when not waiting for any file descriptors. |
| 172 |
- bundle ev.pod into the tarball, just to increase its size |
| 173 |
(and for the poor internetless person). |

|
| 175 |
3.33 Sun May 18 12:43:04 CEST 2008 |
