 Revision history for IO::AIO
 
+TODO: better autoconf.pm that can return LIBS etc.
+
+2.0
+        - aio requests can be cancelled.
+        - add aio_group: aio requests can be grouped.
+        - add aio_sleep mainly for benchmarking and debugging.
+
+1.8  Sat Jun 24 22:20:44 CEST 2006
+	- add and/or document aio_rename, aio_link, aio_symlink and aio_move.
+
+1.73 Wed Mar  1 22:49:32 CET 2006
+	- codename "jost"
+        - AIX/Solaris(?) aren't being helpful again, hardcode a value
+          for NAME_MAX and drive with your eyes closed (reported by
+          wcooley@nakedape.cc).
+
+1.72 Thu Feb  2 00:40:44 CET 2006
+	- another minor bug in aio_scandir, again, the callback was called
+          twice when the directory can't be stat'ed.
+
+1.71 Mon Dec 26 20:20:03 CET 2005
+	- grr, another minor bug in aio_scandir, this time resulting
+          in a runtime error.
+
+1.7  Mon Dec 26 19:29:48 CET 2005
+        - aio_scandir errornously called callback twice in some cases.
+	- added AnyEvent example.
+
+1.61 Wed Sep  7 19:40:42 CEST 2005
+	- no longer include $Config{libs}, as distros include too much
+          garbage in there that is not installed on typical systems
+          (for example, debian links perl against -lgdbm and many more
+          libraries despite perl not needing it, slowing down startup and
+          wasting memory).
+
+1.6  Tue Aug 30 17:44:44 CEST 2005
+        - added aio_readdir, aio_scandir.
+        - added aio_sendfile, including sendfile emulation when sendfile
+          isn't available. 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.
