Revision history for Perl extension EV and the embedded libev library

3.0  Mon Jan 28 13:23:11 CET 2008
	- upgrade to libev-3.0.
        - change child handler to incorporate tracing flag.

2.01 Mon Dec 31 01:59:19 CET 2007
	- found a minor problem in the testsuite that is only
          caught by new Test::Harness versions (reported by Andreas
          König).

2.0  Sat Dec 22 17:47:03 CET 2007
	- no longer force kqueue when enabled, enable it
          on more systems (as its now by default not used on most).
	- expose fork watchers.
        - switch to libev's MULTIPLICITY API.
        - use a slightly different include file name strategy.
        - get rid of (unused) libevent emulation.
        - 5% watcher management speedup due to callback optimisation
          when inline closures are used, 5% slowdown due to multiplicity.
        - very minimal support for dynamic event loops and embed watchers.
        - fix name of prepare start/stop methods.
        - create and export EV::sleep and EV::set_*_collect_interval.
        - fix typos in manpage (Alex Efros).

1.86 Tue Dec 18 02:36:57 CET 2007
        - add periodic->at methods.

1.85 Fri Dec 14 20:32:40 CET 2007
        - further optimise epoll backend by adding a heuristic that
          avoids EPOLL_CTL_DEL calls if possible.
	- EV::signal->start was not async-signal safe.
        - optimise start/stop when the fd hasn't changed.

1.8  Tue Dec 11 22:17:46 CET 2007
	- API version 3:0.
	- reduced fudge factor to zero for select, poll, epoll
          and kqueue: your system better be posix-compliant
          even in its extensions :->
        - improve long-term numerical stability in periodic watchers
          by introducing a separate offset value instead of reusing at.
        - recalculate real/monotonic clocks before blocking fully
          to avoid blocking for longer than necessary.
        - fix bugs in the heap functions. this rarely lead to illegal
          heap orderings.

1.72 Sat Dec  8 15:31:26 CET 2007
	- add dummy loop arguments to some EVAPI functions
          so that clients can use EV_A and EV_DEFAULT.
        - expose ev_clear_pending.
        - renamed trigger to invoke.

1.71 Fri Dec  7 19:10:24 CET 2007
	- changed/implemented idle watcher priority.
	- allow out-of-range priorities to be set.
        - fix ->priority to actually work on started watchers.
        - improved testsuite.

1.6  Wed Dec  5 15:06:20 CET 2007
	- add a missing SPAGAIN.
        - ripped out EV::DNS, use EV::ADNS for a better backend.
        - make ev_time callable from EVAPI.h.
        - add EV::loop_count.
        - some space optimisations.

1.5  Wed Nov 28 20:19:09 CET 2007
	- add inotify backend.
        - make testsuite even less sensible to timing issues,
          add more stat tests.
        - add ->attr, ->prev, ->stat calls to stat watcher.

1.4  Tue Nov 27 17:35:27 CET 2007
	- work around a linux 2.4 kernel bug in child handlers.
        - implement stat watcher interface.
        - implement fork watcher interface.
        - io->set did not keep the fh alive.
        - actively check signal numbers/names to be valid.
        - cleanups, minor fixes, new bugs.
        - work around windows bugs in the testsuite.

1.3  Sun Nov 25 10:46:57 CET 2007
	- stopping idle/check/prepare watchers could cause data corruption.
	- implement and document EV::once.
        - improved documentation, verify that netbsd indeed has the only
          working kqueue implementation (out of darwin, freebsd, netbsd and
          openbsd). Praise them!
        - 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.

1.2  Thu Nov 22 05:44:09 CET 2007
        - disable kqueue by default on !netbsd, as its broken on freebsd,
          darwin and openbsd and thus almost everywhere.
        - add some allowance in t/01_timer.t for the uneven monotonic
          vs. realtime clock tick on at least freebsd.
        - add -lsocket -lnsl on solaris in case the perl guy forgot to
          configure them.

1.1  Wed Nov 21 06:08:48 CET 2007
