Linux, FreeBSD and HP-UX might work (sendfilev + support is unavailable on my solaris 8 machine, but preliminary + code is there. What's lacking is configury stuff and testing...). + +1.5 Sat Aug 20 02:32:19 CEST 2005 + - create the aio threads on demand only (good after forking). + - somebody nagged about C89 compatibility, so this release should + be C89 compatible, but no guarantees for future ones. + - abort when the configure script fails. + +1.4 Wed Aug 17 08:07:27 CEST 2005 + - forget to recreate the pipe after forking, this could cause + deadlocks. + +1.3 Wed Aug 17 07:25:54 CEST 2005 + - properly propagate exceptions from callbacks, instead of silently + eating them. + - use a different fork algorithm that avoids recursive callback + invocations and reduces fork latency in busy processes. + - fix a bug where the buffer scalar in aio_read got assigned the wrong + length after reading. + - fix a bug where the child would process some outstanding requests + from the parent. + - make a copy of the callback scalar, to avoid some very uncommon + (but valid) usages where the callback scalar changes. + - the callback was never freed in aio_read/aio_write. + - aio_read/aio_write will now set the readonly flag on the data + scalar for better error reporting. + +1.2 Wed Aug 17 01:22:58 CEST 2005 + - verified on cygwin, linux/amd64+ia32+alpha, solaris. + - use SvPVbyte for filenames now. You *need* to encode your strings to + the external filename encoding first. + - fix the bug where filehandles could leak (again). + - clarify freebsd situation: make it work and tell me how, or go away + with your underdocumented, broken and outdated OS. + - fork'ing should now be officially supported (where linux and + posix contradict each other, I followed posix). + - only call read() once per poll, not twice (speedup). + - new functions: aio_rmdir, aio_symlink. + - force callback arguments to be undef or a reference, for better + error catching. + +1.1 Sun Aug 7 05:27:23 CEST 2005 + - added configure script to detect availability of some calls. + (imperfect, as we cannot detect things like -lrt due to missing + feedback yet). + - emulate fdatasync via fsync, pread/pwrite via unsafe read/write + and readahead via manual reading on platforms lacking those. + - ported t/03_errors.t+framework by Brad Fitzpatrick + from Linux::AIO. + - removed XOPEN_SOURCE because stupid solaris 9 doesn't + compile with it enabled. Probably breaks others. Oh well. + - try to be more careful with errno on non-threaded perls. + - cygwins perl insisted on a matching open mode when morphing + the fd to an fh. + - convert sv's to "byte" encoding in aio_read/aio_write. Might + do that for pathnames, too, in the future, so make sure you + properly encode your pathnames. + +1.0 Fri Jul 22 10:43:30 CEST 2005 + - aio_open did not reliably deliver (open) filehandles. + - all aio_*-functions keep a reference to the filehandle so + it doesn't go away while the aio requests is working on it. + - disable warnings in AIO.pm. + +0.9 Wed Jul 20 23:55:04 CEST 2005 + - allow recursive calls to poll_cb, use less locking calls, too. + - fix the Gtk2-example in the SYNOPSIS. + - use pread/pwrite not pread64/pwrite64. this was simply a leftover + from Linux::AIO. + (found by compiling on cygwin. Unfortunately, cygwin declares but + does not implement pread/pwrite). + - only include on linux. + +0.5 Tue Jul 12 13:03:09 CEST 2005 + - removed #include , it's not portable, and we don't + need it anyway. + - link against -lrt, as it might contain goodies such as fdatasync, + and often aio_read, which we do not use yet, but it shouldn't hurt. + +0.4 Mon Jul 11 05:28:25 CEST 2005 + - added IO::AIO::flush, IO::AIO::poll. + - make callback argument optional for all calls. + +0.3 Mon Jul 11 01:42:37 CEST 2005 + - restructured manpage. + - added SYNOPSIS with examples for Event, Glib, Tk. + - remove explicit context support so I don't have to maintain + it for threaded perls (i.e. it should work now :). + +0.2 Sun Jul 10 22:57:12 CEST 2005 - return immediately from poll_wait if nreqs==0. - get rid of the request pipe and use faster thread-thread - communications. + communications for most requests and responses. 0.1 - cloned from Linux::AIO, which is very similar.
