Revision history for Perl extension EV
Changes marked with (libev) are changes in libev, and have more
documentation in the libev Changes file.

-
many API changes, see the manual.
-
(libev) lots and lots of bugfixes, see the ev documentation.
-
fix a bug where inotify usage would parse the same event
multiple times, causing various forms of breakage.
-
greatly reduce stack usage for inotify (8kb to <0.5kb).
-
expose ev_depth and ev_verify via the XS API.
-
implement ev_cleanup watchers.
-
(libev) ev_embed_stop did not correctly stop the watcher.

(libev) no child watchers on win32.
-
make code more aliasing compliant, in case perl is ever
translated to C.
-
document the EV::CHECK runtime unavailability.
-
ported to minix 3.1.7.
3.9 Thu Dec 31 07:59:59 CET 2009
-
disable t/07* under automatic testing.
-
increase t/09* timeouts as netbsd has *horribly* broken
select/kevent that *usually* sleep >>0.6s instead of 0.3.
-
add constants EV::FLAG_NOSIGFD, EV::FLAG_NOINOTIFY and
EV::BACKEND_ALL.
-
(libev) signalfd is no longer used by default.
-
(libev) backport inotify code to C89.
-
(libev) inotify file descriptors could leak into child processes.
-
(libev) ev_stat watchers could keep an errornous extra ref on the loop.
-
(libev) take advantage of inotify_init1, if available.
-
(libev) the signal handling pipe wasn't always initialised under windows.
-
changed minimum glibc requirement from glibc 2.9 to 2.7, for signalfd.
-
(libev) only replace ev_stat.prev when we detect an actual difference.
3.8 Sun Aug 9 15:30:10 CEST 2009
-
implement $loop->signal/signal_ns.
-
(libev) incompatible change: do not necessarily reset signal
handler to SIG_DFL when a sighandler is stopped.
-
(libev) ev_default_destroy did not properly free or zero some
members, potentially causing crashes and memory corruption on
repated ev_default_destroy/ev_default_loop calls.
-
(libev) take advantage of signalfd on GNU/Linux systems.
-
(libev) document that the signal mask might be in an unspecified
state when using libev's signal handling.
-
(libev) take advantage of some GNU/Linux calls to set
cloexec/nonblock on fd creation, to avoid race conditions.
-
implement internal glue code to interface more efficiently
with AnyEvent.
3.7 Fri Jul 17 16:49:16 CEST 2009
-
add EV::loop_verify and EV::loop_depth.
-
use output filehandle for i/o watchers waiting
for EV_WRITE, otherwise input filehandle.
-
use common schmorp.h header.
-
add EV::Timer->remaining.
-
allow for subclassing of EV::Loop (see the exciting
EV::Loop::Async module for an example).
-
added EV::invoke_pending and EV::pending_count.
-
(libev) ev_unloop and ev_loop wrongly used a global variable to
exit loops, instead of using a per-loop variable.
-
(libev) the ev_set_io_collect_interval interpretation has changed.
-
add new functionality: EV::invoke_pending, EV::pending_count.
-
add $timer->remaining.
-
add EV::loop_depth.

(libev) calling unloop in fork/prepare watchers will no longer poll
for new events.
-
(libev) use GetSystemTimeAsFileTime instead of _timeb on windows,
for slightly higher accuracy.

(libev) actually 0-initialise struct sigaction when installing
signals.
3.6 Tue Apr 28 02:50:37 CEST 2009
-
keepalive(0) could decrease the refcount of the loop
permanently.
-
add ev_suspend/ev_resume, also make ev_now_update
accessible via the XS API.
-
most EV::<eventtype> constants were missing and have been
added :/.
-
add EV::VERSION_MAJOR/VERSION_MINOR constants.
-
(libev) multiple timers becoming ready within an event loop
iteration will be invoked in the "correct" order now.
-
(libev) do not leave the event loop early just because we have
no active watchers, fixing a problem when embedding a kqueue
loop that has active kernel events but no registered watchers
(reported by blacksand blacksand).
-
(libev) correctly zero the idx values for arrays, so destroying
and reinitialising the default loop actually works (patch by
Malek Hadj-Ali).
-
(libev) new EV::CUSTOM revents flag for use by applications.
-
(libev) add documentation section about priorites.
-
(libev) add a glossary to the dcoumentation.
-
(libev) extend the ev_fork description slightly.
-
(libev) optimize a jump out of call_pending.
-
t/03_keepalive could fail when there was no actual error.
3.53 Sun Feb 15 02:38:20 CET 2009
-
(libev) on win32, the event loop creation could randomly fail
due to an initialised variable having the wrong value.
-
(libev) probe for CLOCK_REALTIME support at runtime as well and
fall back to gettimeofday if there is an error, to support older
operating systems with newer header files/libraries.
-
prefer gettimeofday over clock_gettime by default.
3.52 Wed Jan 7 21:46:14 CET 2009
-
(libev) fix some issues in the select backend when in fd_set mode.
-
(libev) due to a thinko, instead of disabling everything but
select on the borked OS X platform, everything but select was
allowed (reported by Emanuele Giaquinta).
-
(libev) actually verify that local and remote port are matching in
libev's socketpair emulation, which makes denial-of-service
attacks harder (but not impossible - it's windows). Make sure
it even works under vista, which thinks that getpeer/sockname
should return fantasy port numbers.
3.51 Wed Dec 24 23:01:59 CET 2008
-
do not cache the arguments passed to callbacks if the refcount
indicates that the callback has stolen them.
-
(libev) try to avoid librt on GNU/Linux.
-
(libev) check port_getn return value dfferently, might potentially
avoid problems.
-
(libev) fix a bug with stat watchers possibly causing freezes.
-
(libev) work around OS X 10.5 breaking poll, now select is the
only viable choice left on that pile of garbage.
-
play tester whore: disable some tests that typically fail only
on cpan tester machines.
3.49 Wed Nov 19 11:26:53 CET 2008
-
fix typos in manpage (Alex Efros).
-
increase timing even further, for the ever-overloaded cpan-tester
machines, and to the detriment of everybody else who wants a fast
make test.
-
possible 5.6 compatibility.
-
(libev) use inotify even on buggy kernels, but don't rely on it.
-
(libev) use inotify only as an added hint on network filesystems.
3.48 Thu Oct 30 09:09:48 CET 2008
-
(libev) use a generation counter to detect spurious epoll events
and recreate the kernel in such a case (sorry, it's slow, but
I didn't design epoll...).
-
(libev) optimise away an EPOLL_CTL_ADD/MOD combo in the epoll
backend in some cases.
-
(libev) use memset to initialise most arrays now and do away
with the init functions.
-
speed up event callback invocation further (~15%), by
not creating the object reference each time.
-
EV::sleep was documented, but not implemented. fun.
3.45 Tue Oct 21 22:20:39 CEST 2008
-
(libev) disable inotify usage on linux <2.6.25 (kernel bug).
-
(libev) ev_embed will now automatically follow fork.
-
(libev) ev_once will now pass both io and timeout events to
the callback when both happen concurrently, instead of giving
one precedence.
-
install C library documentation as EV::libev manpage (sorry, oesi).
-
(libev) fix a minor performance bug in ev_stat handling.
3.44 Mon Sep 29 05:16:31 CEST 2008
-
(libev) add EV::now_update and $loop->now_update.
3.431 Sun Jul 13 00:19:02 CEST 2008
-
made the EV::embed callback optional again. reported by
Vladimir Timofeev.
3.43 Tue Jul 8 20:56:31 CEST 2008
-
disabled warnings in EV.pm, the CHECK issue is now understood
and harmless.
3.42 Mon May 26 07:36:46 CEST 2008
-
(libev) work around another bug in windows perls and
windows itself: failed connects do NOT set read or write
flags in select, but this version of libev will.
3.41 Thu May 22 01:39:40 CEST 2008
-
(libev) fix many heap-related bugs (timers, periodics).
-
(libev) improve timing stability of timers and periodics.
-
expose ev_loop_verify to perl code.
-
clarify documentation for periodic reschedule callbacks.

reference, for earlier error reporting and a nice calling
speed increase (as well as saving memory).

-
(libev) work around both a windows bug and a bug in perl's
select on windows when not waiting for any file descriptors.
