make sure EV::CHECK is available at all times. + - avoid a spurious warning when perl -w overrides "no warnings". + - use perl's signal implementation on WIN32. + - ensure extern "C" function pointers are used for externally-visible + pointers. + - (libev) mark event pipe fd as cloexec after a fork (analyzed by Sami Farin). + - (ecb) support m68k, m88k and sh (patch by Miod Vallat). + - (libev) in the absence of autoconf, do not use the clock syscall + on glibc >= 2.17 (avoids the syscall AND -lrt on systems + doing clock_gettime in userspace). + - (ecb) work around memory barriers and volatile apparently both being + broken in visual studio 2008 and later (analysed and patch by Nicolas Noble). + +4.15 Fri Mar 1 12:15:53 CET 2013 + - (libev) upgrade to 4.15 - too many changes to list. + - EV::run now returns a boolean. + - API version 5:1. + - document that cleanup watchers are not available via perl. + - cast I32 to int in error message printf. + - remove dependencies on librt and libpthreads on GNU/Linux. + +4.11 Sat Feb 4 19:56:26 CET 2012 + - (libev) implement memory fences for (obsolete) llvm-gcc. + +4.10 Thu Jan 19 18:54:23 CET 2012 + - (libev) fix a race where the workaround against the epoll fork + bugs caused signals to not be handled anymore. + - (libev) correct backend_fudge for most backends, and implement + a windows specific workaround to avoid looping because we call + both select and Sleep, both with different time resolutions. + - e_new wasn't declared static (causing very minor .so bloat). + - replace more old api names by new ones. + +4.03 Tue Jan 11 14:51:05 CET 2011 + - do not avoid the clock_gettime call on GNU/Linux anymore, as EV + links against -lpthread anyways - as a result, EV might now take + advantage of fast userspace clock_gettime implementations, + but also links against -lrt. + - (libev) lots of event port bug workarounds. + - (libev) officially support files in I/O watchers. + - (libev) new function ev_feed_signal. + - fix documentation parts still refering to the 3.x API. + +4.02 Thu Dec 30 08:27:41 CET 2010 + - the revents argument did not stringify correctly, as only the + numeric value was updated, while the string value was kept from + previous invocations. + +4.01 Sun Dec 5 12:42:13 CET 2010 + - fully support EV_COMPAT3=0. + - default_fork was stupidly defined as inline. + - ask cpan to upgrade AnyEvent if < 5.29. + - support EV_EXTRA_DEFS during configuration. + - support -DEV_NO_LOOPS for snakker build. + +4.00 Mon Oct 25 13:30:09 CEST 2010 + - 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) disable poll backend on AIX. + - (libev) rename EV_TIMEOUT to EV_TIMER. + - (libev) add section on accept() problems to the manpage. + - (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:: 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).
