52.0 93.07 Sat Aug 2 16:06:13 CEST 2008
6 - INCOMPATIBLE CHANGE: max_outstanding was removed, use 10 - do not include LIBS in autoconf tests.
7 a group with a feeder instead. 11
123.06 Tue Jul 15 12:41:32 CEST 2008
13 - move preadwritelock definition before it's first reference,
14 to make it compile again on broken platforms (they still exist)
15 or badly cofngiured perls (redhat...), reported by Rob Bloodgood.
16
173.05 Thu Jun 19 23:23:52 CEST 2008
18 - work around perl overriding readdir etc. with thread-unsafe
19 (sic!) versions.
20
213.04 Wed Jun 18 01:35:38 CEST 2008
22 - (libeio) fix eio_mknod, which confused it's arguments.
23 - (libeio) do not use readdir_r, as Ulrich Drepper pointed out that this
24 is stupid.
25 - (libeio) fix eio__readahead prototype, patch by Jost Krieger.
26 - (libeio) fix a bug that could potentially cause IO::AIO
27 not to get initialised properly.
28
293.03 Thu May 29 05:33:30 CEST 2008
30 - (libeio) correctly call pthread_attr_destroy ().
31 - (libeio) work around broken bsd headers once more.
32 - reduce shared library size again by not including wrappers.
33 - max_outstanding could cause poll to enter a busy-waiting loop.
34 - document the new IO::AIO::poll_cb result value.
35
363.02 Mon May 12 02:32:02 CEST 2008
37 - fix a memory leak on aio_readlink.
38 - bring back working fchmod.
39 - nop and busy now set result to 0.
40 - set errno to ENOMEM when allocation fails.
41
423.01 Sun May 11 03:07:03 CEST 2008
43 - (libeio) make it compile on systems without readahead or readdir_r.
44 - (libeio) improve configure check for readahead availability.
45 - do not try to link against -lrt.
46 - use a separate configure script for IO::AIO (not the libeio one).
47
483.0 Sun May 11 00:57:14 CEST 2008
49 - added bin/treescan to the distribution.
50 - switched to using libeio.
51 - LOTS OF INCOMPATIBLE CHANGES:
52 - remove signal functionality, it is not worth the effort.
53 - max_outstanding no longer returns the previous number of requests.
54 - poll_cb no longer returns number of requests.
55
562.62 Sat Apr 26 13:59:33 CEST 2008
57 - port to solaris perls configured for old posix
58 (analysed by Jost Krieger).
59 - keep a reference to the perl filehandle object in aio_close,
60 so it doesn't get closed prematurely, leading to ugly races.
61
622.61 Wed Apr 16 18:45:02 CEST 2008
63 - fix treescan output duplication and improve output ordering.
64 also display files given on the commandline.
65 - use a different algorithm for aio_close that is faster
66 and probably has even lower chances of blocking.
67 - do our own stack memory management for threads - linux
68 allocates outrageous amounts of VM (not so bad unless you
69 use mlockall...), which severely limits the number of threads
70 on 32-bit arches: stack size is the larger of PTHREAD_STACK_MIN
71 and 4096 * sizeof (long) (usually this is 16..64k).
72
732.6 Sun Mar 30 08:28:11 CEST 2008
74 - added aio_sync.
75 - added aio_pathsync.
76 - fix prototypes of (void) functions.
77
782.51 Sat Oct 6 16:04:54 CEST 2007
79 - perlio isn't generally threadsafe, so aio_close could not work reliably.
80 aio_close now tries a safe hack that might not be that asynchronous
81 (see the manpage for details).
82 - discard callback return values as to not grow the stack endlessly
83 when poll_cb handles many requests without returning.
84 - minor code cleanups.
85
862.5 Thu Oct 4 14:49:08 CEST 2007
87 - replaced _fd2fh with faster xs code.
88 - aio_close will now try to do "the right thing" and thus might
89 work sensibly for the very first time.
90
912.41 Mon Sep 24 21:28:21 CEST 2007
92 - after fork, invest some work to make sure that the poll_fileno
93 stays stable (by dup2'ing the new fd over the old one), to make
94 it easier for programs/libs that don't control their forking
95 behaviour and cannot recreate their watchers.
96
972.4 Sun Aug 5 18:44:22 CEST 2007
98 - add aio_truncate, aio_chmod, aio_chown, aio_utime (linux
99 successfully demonstrated that you can block on futimes...).
100 - allow undef as fileoffset for aio_read/write and use read/write(2)
101 internally (useful for sockets or O_APPEND handles).
102 - allow undef for length in aio_write.
103 - negative dataoffsets work as expected now in aio_read/aio_write.
104 - use NV instead of UV for 32 bit perls and file offsets, as NVs
105 have a larger range then.
106 - shared code between BDB and IO::AIO.
107 - aio_busy was completely broken. now fixed.
108 - readahead emulation now returns something.
109 - correctly set errno to ENOSYS on unimplemented functions
110 (should never happen, though).
111 - large changes to make it partially compile and run on win32,
112 but win32 lacks too much functionality, and perl overrides way
113 too many functions with crashing versions.
114
1152.33 Tue Jan 23 23:55:41 CET 2007
116 - fix install path (Andreas J. Koenig).
117
1182.32 Mon Jan 22 16:56:23 CET 2007
119 - added aio_rmtree.
120 - wow, aio_mkdir was missing.
121 - aio_load did return undef on error, not -1.
122 - use prefixexp not prefix in autoconf.pm
123 (suggested by ... rt.cpan.org unreachable).
124 - avoid installing autoconf.pm.
125
1262.31 Sat Jan 6 03:46:02 CET 2007
127 - added aio_load.
128
1292.3 Sat Dec 23 05:48:07 CET 2006
130 - fix off-by-one bug in aio_read, causing memory corruption
131 or crashes.
132
1332.21 Fri Dec 22 05:03:38 CET 2006
134 - minor doc updates.
135 - minor cleanups.

138
1392.2 Tue Oct 31 00:31:00 CET 2006
140 - minor doc updates.
141 - added aio_readlink.
142 - properly zero-terminate aio_read buffer.
143 - fix aio_read/write with nonzero dataoffset.
144 - reduced size of aio request structure.
145 - better diagnostics when pathnames etc. are not byte-encoded;
146 do not leak request in that case, either.
147
1482.1 Sun Oct 29 02:01:57 CET 2006
149 - INCOMPATIBLE CHANGE: replace IO::AIO::poll_some by
150 IO::AIO::max_poll_reqs and IO::AIO::max_poll_time.
151 - fix a bug in aio_move where it would fail everytime
152 it would have to copy files manually.
153 - doc updates.
154 - start threads only on (very low) demand.
155 - end superfluous threads automatically after 10s idling.
156 - add IO::AIO::max_idle to control this.
157 - some tuning applied to random places.
158 - add aio_mknod.
