Revision history for Perl extension EV

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

          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).

        - expose ev_loop_verify to perl code.
        - clarify documentation for periodic reschedule callbacks.
        - verify that the passed callback argument is indeed a code
          reference, for earlier error reporting and a nice calling
          speed increase (as well as saving memory).

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

        - API version 3:0.

        - improved documentation, verify that netbsd indeed has the only

        - fix the data method so it might work.
        - expose ev_ref/ev_unref to the C API.
        - expose ref/unref in form of the ->keepalive method to perl.
        - minor bugfixes and portability fixes.
