72.2 93.01 Sun May 11 03:07:03 CEST 2008
10 - (libeio) make it compile on systems without readahead or readdir_r.
11 - (libeio) improve configure check for readahead availability.
12 - do not try to link against -lrt.
13 - use a separate configure script for IO::AIO (not the libeio one).
14
153.0 Sun May 11 00:57:14 CEST 2008
16 - added bin/treescan to the distribution.
17 - switched to using libeio.
18 - LOTS OF INCOMPATIBLE CHANGES:
19 - remove signal functionality, it is not worth the effort.
20 - max_outstanding no longer returns the previous number of requests.
21 - poll_cb no longer returns number of requests.
22
232.62 Sat Apr 26 13:59:33 CEST 2008
24 - port to solaris perls configured for old posix
25 (analysed by Jost Krieger).
26 - keep a reference to the perl filehandle object in aio_close,
27 so it doesn't get closed prematurely, leading to ugly races.
28
292.61 Wed Apr 16 18:45:02 CEST 2008
30 - fix treescan output duplication and improve output ordering.
31 also display files given on the commandline.
32 - use a different algorithm for aio_close that is faster
33 and probably has even lower chances of blocking.
34 - do our own stack memory management for threads - linux
35 allocates outrageous amounts of VM (not so bad unless you
36 use mlockall...), which severely limits the number of threads
37 on 32-bit arches: stack size is the larger of PTHREAD_STACK_MIN
38 and 4096 * sizeof (long) (usually this is 16..64k).
39
402.6 Sun Mar 30 08:28:11 CEST 2008
41 - added aio_sync.
42 - added aio_pathsync.
43 - fix prototypes of (void) functions.
44
452.51 Sat Oct 6 16:04:54 CEST 2007
46 - perlio isn't generally threadsafe, so aio_close could not work reliably.
47 aio_close now tries a safe hack that might not be that asynchronous
48 (see the manpage for details).
49 - discard callback return values as to not grow the stack endlessly
50 when poll_cb handles many requests without returning.
51 - minor code cleanups.
52
532.5 Thu Oct 4 14:49:08 CEST 2007
54 - replaced _fd2fh with faster xs code.
55 - aio_close will now try to do "the right thing" and thus might
56 work sensibly for the very first time.
57
582.41 Mon Sep 24 21:28:21 CEST 2007
59 - after fork, invest some work to make sure that the poll_fileno
60 stays stable (by dup2'ing the new fd over the old one), to make
61 it easier for programs/libs that don't control their forking
62 behaviour and cannot recreate their watchers.
63
642.4 Sun Aug 5 18:44:22 CEST 2007
65 - add aio_truncate, aio_chmod, aio_chown, aio_utime (linux
66 successfully demonstrated that you can block on futimes...).
67 - allow undef as fileoffset for aio_read/write and use read/write(2)
68 internally (useful for sockets or O_APPEND handles).
69 - allow undef for length in aio_write.
70 - negative dataoffsets work as expected now in aio_read/aio_write.
71 - use NV instead of UV for 32 bit perls and file offsets, as NVs
72 have a larger range then.
73 - shared code between BDB and IO::AIO.
74 - aio_busy was completely broken. now fixed.
75 - readahead emulation now returns something.
76 - correctly set errno to ENOSYS on unimplemented functions
77 (should never happen, though).
78 - large changes to make it partially compile and run on win32,
79 but win32 lacks too much functionality, and perl overrides way
80 too many functions with crashing versions.
81
822.33 Tue Jan 23 23:55:41 CET 2007
83 - fix install path (Andreas J. Koenig).
84
852.32 Mon Jan 22 16:56:23 CET 2007
86 - added aio_rmtree.
87 - wow, aio_mkdir was missing.
88 - aio_load did return undef on error, not -1.
89 - use prefixexp not prefix in autoconf.pm
90 (suggested by ... rt.cpan.org unreachable).
91 - avoid installing autoconf.pm.
92
932.31 Sat Jan 6 03:46:02 CET 2007
94 - added aio_load.
95
962.3 Sat Dec 23 05:48:07 CET 2006
97 - fix off-by-one bug in aio_read, causing memory corruption
98 or crashes.
99
1002.21 Fri Dec 22 05:03:38 CET 2006
101 - minor doc updates.
102 - minor cleanups.
103 - IO::AIO::poll returns request count.
104 - undocumented and unfinished async-signal-reporting.
105
1062.2 Tue Oct 31 00:31:00 CET 2006
8 - minor doc updates. 107 - minor doc updates.
9 - added aio_readlink. 108 - added aio_readlink.
10 - properly zero-terminate aio_read buffer. 109 - properly zero-terminate aio_read buffer.
11 - fix aio_read/write with nonzero dataoffset. 110 - fix aio_read/write with nonzero dataoffset.
111 - reduced size of aio request structure.
112 - better diagnostics when pathnames etc. are not byte-encoded;
113 do not leak request in that case, either.

14 - INCOMPATIBLE CHANGE: replace IO::AIO::poll_some by 116 - INCOMPATIBLE CHANGE: replace IO::AIO::poll_some by
15 IO::AIO::max_poll_reqs and IO::AIO::max_poll_time. 117 IO::AIO::max_poll_reqs and IO::AIO::max_poll_time.
16 - fix a bug in aio_move where it would fail everytime 118 - fix a bug in aio_move where it would fail everytime
