93.05 Thu Jun 19 23:23:52 CEST 2008
10 - work around perl overriding readdir etc. with thread-unsafe
11 (sic!) versions.
12
133.04 Wed Jun 18 01:35:38 CEST 2008
14 - (libeio) fix eio_mknod, which confused it's arguments.
15 - (libeio) do not use readdir_r, as Ulrich Drepper pointed out that this
16 is stupid.
17 - (libeio) fix eio__readahead prototype, patch by Jost Krieger.
18 - (libeio) fix a bug that could potentially cause IO::AIO
19 not to get initialised properly.
20
213.03 Thu May 29 05:33:30 CEST 2008
22 - (libeio) correctly call pthread_attr_destroy ().
23 - (libeio) work around broken bsd headers once more.
24 - reduce shared library size again by not including wrappers.
25 - max_outstanding could cause poll to enter a busy-waiting loop.
26 - document the new IO::AIO::poll_cb result value.
27
283.02 Mon May 12 02:32:02 CEST 2008
29 - fix a memory leak on aio_readlink.
30 - bring back working fchmod.
31 - nop and busy now set result to 0.
32 - set errno to ENOMEM when allocation fails.
33
343.01 Sun May 11 03:07:03 CEST 2008
35 - (libeio) make it compile on systems without readahead or readdir_r.
36 - (libeio) improve configure check for readahead availability.
37 - do not try to link against -lrt.
38 - use a separate configure script for IO::AIO (not the libeio one).
39
403.0 Sun May 11 00:57:14 CEST 2008
41 - added bin/treescan to the distribution.
42 - switched to using libeio.
43 - LOTS OF INCOMPATIBLE CHANGES:
44 - remove signal functionality, it is not worth the effort.
45 - max_outstanding no longer returns the previous number of requests.
46 - poll_cb no longer returns number of requests.
47
482.62 Sat Apr 26 13:59:33 CEST 2008
49 - port to solaris perls configured for old posix
50 (analysed by Jost Krieger).
51 - keep a reference to the perl filehandle object in aio_close,
52 so it doesn't get closed prematurely, leading to ugly races.
53
542.61 Wed Apr 16 18:45:02 CEST 2008
55 - fix treescan output duplication and improve output ordering.
56 also display files given on the commandline.
57 - use a different algorithm for aio_close that is faster
58 and probably has even lower chances of blocking.
59 - do our own stack memory management for threads - linux
60 allocates outrageous amounts of VM (not so bad unless you
61 use mlockall...), which severely limits the number of threads
62 on 32-bit arches: stack size is the larger of PTHREAD_STACK_MIN
63 and 4096 * sizeof (long) (usually this is 16..64k).
64
652.6 Sun Mar 30 08:28:11 CEST 2008
66 - added aio_sync.
67 - added aio_pathsync.
68 - fix prototypes of (void) functions.
69
702.51 Sat Oct 6 16:04:54 CEST 2007
71 - perlio isn't generally threadsafe, so aio_close could not work reliably.
72 aio_close now tries a safe hack that might not be that asynchronous
73 (see the manpage for details).
74 - discard callback return values as to not grow the stack endlessly
75 when poll_cb handles many requests without returning.
76 - minor code cleanups.
77
782.5 Thu Oct 4 14:49:08 CEST 2007
79 - replaced _fd2fh with faster xs code.
80 - aio_close will now try to do "the right thing" and thus might
81 work sensibly for the very first time.
82
832.41 Mon Sep 24 21:28:21 CEST 2007
84 - after fork, invest some work to make sure that the poll_fileno
85 stays stable (by dup2'ing the new fd over the old one), to make
86 it easier for programs/libs that don't control their forking
87 behaviour and cannot recreate their watchers.
88
892.4 Sun Aug 5 18:44:22 CEST 2007
90 - add aio_truncate, aio_chmod, aio_chown, aio_utime (linux
91 successfully demonstrated that you can block on futimes...).
92 - allow undef as fileoffset for aio_read/write and use read/write(2)
93 internally (useful for sockets or O_APPEND handles).
94 - allow undef for length in aio_write.
95 - negative dataoffsets work as expected now in aio_read/aio_write.
96 - use NV instead of UV for 32 bit perls and file offsets, as NVs
97 have a larger range then.
98 - shared code between BDB and IO::AIO.
99 - aio_busy was completely broken. now fixed.
100 - readahead emulation now returns something.
101 - correctly set errno to ENOSYS on unimplemented functions
102 (should never happen, though).
103 - large changes to make it partially compile and run on win32,
104 but win32 lacks too much functionality, and perl overrides way
105 too many functions with crashing versions.
106
1072.33 Tue Jan 23 23:55:41 CET 2007
108 - fix install path (Andreas J. Koenig).
109
1102.32 Mon Jan 22 16:56:23 CET 2007
111 - added aio_rmtree.
112 - wow, aio_mkdir was missing.
113 - aio_load did return undef on error, not -1.
114 - use prefixexp not prefix in autoconf.pm
115 (suggested by ... rt.cpan.org unreachable).
116 - avoid installing autoconf.pm.
117
1182.31 Sat Jan 6 03:46:02 CET 2007
119 - added aio_load.
120
1212.3 Sat Dec 23 05:48:07 CET 2006
122 - fix off-by-one bug in aio_read, causing memory corruption
123 or crashes.
124
1252.21 Fri Dec 22 05:03:38 CET 2006
126 - minor doc updates.
127 - minor cleanups.
128 - IO::AIO::poll returns request count.
129 - undocumented and unfinished async-signal-reporting.

11 - fix aio_read/write with nonzero dataoffset. 135 - fix aio_read/write with nonzero dataoffset.
12 - reduced size of aio request structure. 136 - reduced size of aio request structure.
13 - better diagnostics when pathnames etc. are unicode-encoded, 137 - better diagnostics when pathnames etc. are not byte-encoded;
14 do not leak request in that case, either. 138 do not leak request in that case, either.

162.1 Sun Oct 29 02:01:57 CET 2006 1402.1 Sun Oct 29 02:01:57 CET 2006
17 - INCOMPATIBLE CHANGE: replace IO::AIO::poll_some by 141 - INCOMPATIBLE CHANGE: replace IO::AIO::poll_some by
18 IO::AIO::max_poll_reqs and IO::AIO::max_poll_time. 142 IO::AIO::max_poll_reqs and IO::AIO::max_poll_time.
