I knew + they could implement fork and semaphores one day! cheers! + +3.4 Sat Jan 2 15:13:04 CET 2010 + - (libeio) max_poll_time was not properly converted to ticks. + - clarify cancel_subs description. + - IO::AIO::sendfile did not actually return the return value + from the sendfile call. + - implement aio_msync, aio_mtouch. + - (libeio) tentatively support darwin in sendfile. + +3.31 Thu Nov 12 02:14:29 CET 2009 + - fix result status documentation of aio_copy, aio_move. + - speed up object creation considerably by avoiding + hash lookups. + +3.3 Wed Aug 5 13:52:58 CEST 2009 + - use common::sense. + - use common schmorp.h header. + - allow integers (file descriptors) in addition to file handles. + - take advantage of linux' eventfd (but it seems slower on smp?). + - use poll not select on posix platforms. + +3.261 Wed Jul 1 10:11:51 CEST 2009 + - more 0S X workarounds (patch by Tokuhiro Matsuno). + +3.26 Tue Jun 30 09:33:26 CEST 2009 + - 0S X of course claims to be posix 2008 but lacks posix_fadvise. + try to work around this horribly broken OS in a somewhat hackish + way. might help other os's too. + +3.25 Sat Jun 27 05:18:26 CEST 2009 + - added IO::AIO::fadvise and IO::AIO::sendfile. + - (libeio) replaced quicksort+insertion sort by a tuned radix + sort + insertion sort, resulting in comparable runtime (usually + faster) to the old version, but without any ill side effects on + degenerated (for quicksort) data. + - (libeio) correctly sort dirs by inodes if we have perfect type + knowledge and DIRS_FIRST is used. + - (libeio) internally the wrong DT_* constants were used, but no + known system has differing EIO_DT_*/DT_* values, so not an issue. + - removed a (harmless) assert that was left over on the code + but should not have been. + - use more correct types (change IO length from IV to VAL64, + which makes a difference on systems without 64 bit perls). + +3.23 Sat Jun 13 16:57:58 CEST 2009 + - fix off-by-one bug in aio_readdir that was introduced in the + rushed 3.22 release. + +3.22 Sat Jun 13 15:32:40 CEST 2009 + - speed up readdirx sort algorithm slightly. + - bin/treescan was missing from distro tarball. + +3.21 Fri Jun 12 18:45:53 CEST 2009 + - new options --dirs and --files for treescan. + - install bin/treescan by default. + - (libeio) aio_readdir can now be cancelled while executing. + - fix a printf format string for 64 bit systems (could lead + to problems on big endian 64 bit systems). + - do not use qsort() but our own algorithm: glibc initialises + the whole locale and I/O subsystem inside qsort, causing + a stack overflow on 32 bit machines.
