9 - move preadwritelock definition before it's first reference,
10 to make it compile again on broken platforms (they still exist).
11 reported by Rob Bloodgood.
12
133.05 Thu Jun 19 23:23:52 CEST 2008
14 - work around perl overriding readdir etc. with thread-unsafe
15 (sic!) versions.
16
173.04 Wed Jun 18 01:35:38 CEST 2008
18 - (libeio) fix eio_mknod, which confused it's arguments.
19 - (libeio) do not use readdir_r, as Ulrich Drepper pointed out that this
20 is stupid.
21 - (libeio) fix eio__readahead prototype, patch by Jost Krieger.
22 - (libeio) fix a bug that could potentially cause IO::AIO
23 not to get initialised properly.
24
253.03 Thu May 29 05:33:30 CEST 2008
26 - (libeio) correctly call pthread_attr_destroy ().
27 - (libeio) work around broken bsd headers once more.
28 - reduce shared library size again by not including wrappers.
29 - max_outstanding could cause poll to enter a busy-waiting loop.
30 - document the new IO::AIO::poll_cb result value.
31
323.02 Mon May 12 02:32:02 CEST 2008
33 - fix a memory leak on aio_readlink.
34 - bring back working fchmod.
35 - nop and busy now set result to 0.
36 - set errno to ENOMEM when allocation fails.
37
383.01 Sun May 11 03:07:03 CEST 2008
39 - (libeio) make it compile on systems without readahead or readdir_r.
40 - (libeio) improve configure check for readahead availability.
41 - do not try to link against -lrt.
42 - use a separate configure script for IO::AIO (not the libeio one).
43
443.0 Sun May 11 00:57:14 CEST 2008
45 - added bin/treescan to the distribution.
46 - switched to using libeio.
47 - LOTS OF INCOMPATIBLE CHANGES:
48 - remove signal functionality, it is not worth the effort.
49 - max_outstanding no longer returns the previous number of requests.
50 - poll_cb no longer returns number of requests.
51
522.62 Sat Apr 26 13:59:33 CEST 2008
53 - port to solaris perls configured for old posix
54 (analysed by Jost Krieger).
55 - keep a reference to the perl filehandle object in aio_close,
56 so it doesn't get closed prematurely, leading to ugly races.
57
582.61 Wed Apr 16 18:45:02 CEST 2008
59 - fix treescan output duplication and improve output ordering.
60 also display files given on the commandline.
61 - use a different algorithm for aio_close that is faster
62 and probably has even lower chances of blocking.
63 - do our own stack memory management for threads - linux
64 allocates outrageous amounts of VM (not so bad unless you
65 use mlockall...), which severely limits the number of threads
66 on 32-bit arches: stack size is the larger of PTHREAD_STACK_MIN
67 and 4096 * sizeof (long) (usually this is 16..64k).
68
692.6 Sun Mar 30 08:28:11 CEST 2008
70 - added aio_sync.
71 - added aio_pathsync.
72 - fix prototypes of (void) functions.
73
742.51 Sat Oct 6 16:04:54 CEST 2007
75 - perlio isn't generally threadsafe, so aio_close could not work reliably.
76 aio_close now tries a safe hack that might not be that asynchronous
77 (see the manpage for details).
78 - discard callback return values as to not grow the stack endlessly
79 when poll_cb handles many requests without returning.
80 - minor code cleanups.
81
822.5 Thu Oct 4 14:49:08 CEST 2007
83 - replaced _fd2fh with faster xs code.
84 - aio_close will now try to do "the right thing" and thus might
85 work sensibly for the very first time.
86
872.41 Mon Sep 24 21:28:21 CEST 2007
88 - after fork, invest some work to make sure that the poll_fileno
89 stays stable (by dup2'ing the new fd over the old one), to make
90 it easier for programs/libs that don't control their forking
91 behaviour and cannot recreate their watchers.
92
932.4 Sun Aug 5 18:44:22 CEST 2007
94 - add aio_truncate, aio_chmod, aio_chown, aio_utime (linux
95 successfully demonstrated that you can block on futimes...).
96 - allow undef as fileoffset for aio_read/write and use read/write(2)
97 internally (useful for sockets or O_APPEND handles).
98 - allow undef for length in aio_write.
99 - negative dataoffsets work as expected now in aio_read/aio_write.
100 - use NV instead of UV for 32 bit perls and file offsets, as NVs
101 have a larger range then.
102 - shared code between BDB and IO::AIO.
103 - aio_busy was completely broken. now fixed.
104 - readahead emulation now returns something.
105 - correctly set errno to ENOSYS on unimplemented functions
106 (should never happen, though).
107 - large changes to make it partially compile and run on win32,
108 but win32 lacks too much functionality, and perl overrides way
109 too many functions with crashing versions.
110
1112.33 Tue Jan 23 23:55:41 CET 2007
112 - fix install path (Andreas J. Koenig).
113
1142.32 Mon Jan 22 16:56:23 CET 2007
115 - added aio_rmtree.
116 - wow, aio_mkdir was missing.
117 - aio_load did return undef on error, not -1.
118 - use prefixexp not prefix in autoconf.pm
119 (suggested by ... rt.cpan.org unreachable).
120 - avoid installing autoconf.pm.
121
1222.31 Sat Jan 6 03:46:02 CET 2007
123 - added aio_load.
124
1252.3 Sat Dec 23 05:48:07 CET 2006
126 - fix off-by-one bug in aio_read, causing memory corruption
127 or crashes.
128
1292.21 Fri Dec 22 05:03:38 CET 2006
130 - minor doc updates.
131 - minor cleanups.
132 - IO::AIO::poll returns request count.
133 - undocumented and unfinished async-signal-reporting.

8 - minor doc updates. 136 - minor doc updates.
9 - added aio_readlink. 137 - added aio_readlink.
10 - properly zero-terminate aio_read buffer. 138 - properly zero-terminate aio_read buffer.
11 - fix aio_read/write with nonzero dataoffset. 139 - fix aio_read/write with nonzero dataoffset.
12 - reduced size of aio request structure. 140 - reduced size of aio request structure.
13 - better diagnostics when pathnames etc. are unicode-encoded, 141 - better diagnostics when pathnames etc. are not byte-encoded;
14 do not leak request in that case, either. 142 do not leak request in that case, either.

162.1 Sun Oct 29 02:01:57 CET 2006 1442.1 Sun Oct 29 02:01:57 CET 2006
17 - INCOMPATIBLE CHANGE: replace IO::AIO::poll_some by 145 - INCOMPATIBLE CHANGE: replace IO::AIO::poll_some by
18 IO::AIO::max_poll_reqs and IO::AIO::max_poll_time. 146 IO::AIO::max_poll_reqs and IO::AIO::max_poll_time.
