92.4 93.19 Tue Apr 21 22:05:21 CEST 2009
10 - fix aio_busy w.r.t. fractional delays. 10 - more perl 5.10 workarounds for aio_read and write.
11 - add aio_chmod, aio_chown, aio_utime (linux successfully demonstrated 11 - aio_write no longer modifies the sv (if possible).
12 - aio_read now works correctly with magic values.
13
143.18 Sun Apr 19 21:17:32 CEST 2009
15 - better diagnostics when some aio_* functions get passed an illegal fh.
16 - try to avoid crashes due to incompatible 5.10 API changes. grmbl.
17
183.17 Thu Nov 20 08:45:36 CET 2008
19 - (libeio) added aio_sync_file_range (untested).
20 - add aio_busy to @IO::AIO::AIO_REQ.
21
223.16 Wed Oct 22 18:28:01 CEST 2008
23 - use SvREFCNT_inc instead of SvREFCNT_inc_NN in a non-speed critical
24 part to improve portability to perl 5.8 (reported by szymon).
25
263.15 Mon Oct 13 00:39:55 CEST 2008
27 - automatic removal of feeders was broken.
28 - (libeio) use a more robust method to detect whether a feeder
29 has added something to the group or not.
30
313.1 Thu Oct 2 13:34:40 CEST 2008
32 - pre-deref the passed callback object, for increased speed
33 and decreased memory usage.
34 - call on_next_submit callback even for aio_group - impact unknown,
35 but seems more correct.
36 - $req->cb now returns the original callback.
37 - (libeio) pass EIO_GROUP/aio_group requests through the queue without
38 requiring a thread switch.
39 - (libeio) status code of aio_futime and aio_utime was always passed 0.
40 - do some other ยต-optimisations.
41
423.07 Sat Aug 2 16:06:13 CEST 2008
43 - do not include LIBS in autoconf tests.
44
453.06 Tue Jul 15 12:41:32 CEST 2008
46 - move preadwritelock definition before it's first reference,
47 to make it compile again on broken platforms (they still exist)
48 or badly cofngiured perls (redhat...), reported by Rob Bloodgood.
49
503.05 Thu Jun 19 23:23:52 CEST 2008
51 - work around perl overriding readdir etc. with thread-unsafe
52 (sic!) versions.
53
543.04 Wed Jun 18 01:35:38 CEST 2008
55 - (libeio) fix eio_mknod, which confused it's arguments.
56 - (libeio) do not use readdir_r, as Ulrich Drepper pointed out that this
57 is stupid.
58 - (libeio) fix eio__readahead prototype, patch by Jost Krieger.
59 - (libeio) fix a bug that could potentially cause IO::AIO
60 not to get initialised properly.
61
623.03 Thu May 29 05:33:30 CEST 2008
63 - (libeio) correctly call pthread_attr_destroy ().
64 - (libeio) work around broken bsd headers once more.
65 - reduce shared library size again by not including wrappers.
66 - max_outstanding could cause poll to enter a busy-waiting loop.
67 - document the new IO::AIO::poll_cb result value.
68
693.02 Mon May 12 02:32:02 CEST 2008
70 - fix a memory leak on aio_readlink.
71 - bring back working fchmod.
72 - nop and busy now set result to 0.
73 - set errno to ENOMEM when allocation fails.
74
753.01 Sun May 11 03:07:03 CEST 2008
76 - (libeio) make it compile on systems without readahead or readdir_r.
77 - (libeio) improve configure check for readahead availability.
78 - do not try to link against -lrt.
79 - use a separate configure script for IO::AIO (not the libeio one).
80
813.0 Sun May 11 00:57:14 CEST 2008
82 - added bin/treescan to the distribution.
83 - switched to using libeio.
84 - LOTS OF INCOMPATIBLE CHANGES:
85 - remove signal functionality, it is not worth the effort.
86 - max_outstanding no longer returns the previous number of requests.
87 - poll_cb no longer returns number of requests.
88
892.62 Sat Apr 26 13:59:33 CEST 2008
90 - port to solaris perls configured for old posix
91 (analysed by Jost Krieger).
92 - keep a reference to the perl filehandle object in aio_close,
93 so it doesn't get closed prematurely, leading to ugly races.
94
952.61 Wed Apr 16 18:45:02 CEST 2008
96 - fix treescan output duplication and improve output ordering.
97 also display files given on the commandline.
98 - use a different algorithm for aio_close that is faster
99 and probably has even lower chances of blocking.
100 - do our own stack memory management for threads - linux
101 allocates outrageous amounts of VM (not so bad unless you
102 use mlockall...), which severely limits the number of threads
103 on 32-bit arches: stack size is the larger of PTHREAD_STACK_MIN
104 and 4096 * sizeof (long) (usually this is 16..64k).
105
1062.6 Sun Mar 30 08:28:11 CEST 2008
107 - added aio_sync.
108 - added aio_pathsync.
109 - fix prototypes of (void) functions.
110
1112.51 Sat Oct 6 16:04:54 CEST 2007
112 - perlio isn't generally threadsafe, so aio_close could not work reliably.
113 aio_close now tries a safe hack that might not be that asynchronous
114 (see the manpage for details).
115 - discard callback return values as to not grow the stack endlessly
116 when poll_cb handles many requests without returning.
117 - minor code cleanups.
118
1192.5 Thu Oct 4 14:49:08 CEST 2007
120 - replaced _fd2fh with faster xs code.
121 - aio_close will now try to do "the right thing" and thus might
122 work sensibly for the very first time.
123
1242.41 Mon Sep 24 21:28:21 CEST 2007
125 - after fork, invest some work to make sure that the poll_fileno
126 stays stable (by dup2'ing the new fd over the old one), to make
127 it easier for programs/libs that don't control their forking
128 behaviour and cannot recreate their watchers.
129
1302.4 Sun Aug 5 18:44:22 CEST 2007
131 - add aio_truncate, aio_chmod, aio_chown, aio_utime (linux
12 that you can block on futimes...). 132 successfully demonstrated that you can block on futimes...).
13 - allow undef as fileoffset for aio_read/write and use read/write(2) 133 - allow undef as fileoffset for aio_read/write and use read/write(2)
14 internally (useful for sockets or O_APPEND handles). 134 internally (useful for sockets or O_APPEND handles).
135 - allow undef for length in aio_write.
136 - negative dataoffsets work as expected now in aio_read/aio_write.
15 - use NV instead of UV for 32 bit perls and file offsets, as NVs 137 - use NV instead of UV for 32 bit perls and file offsets, as NVs
16 have a larger range then. 138 have a larger range then.
17 - shared code between BDB and IO::AIO. 139 - shared code between BDB and IO::AIO.
140 - aio_busy was completely broken. now fixed.
141 - readahead emulation now returns something.
18 - correctly set errno to ENOSYS on unimplemented functions 142 - correctly set errno to ENOSYS on unimplemented functions
19 (should never happen, though). 143 (should never happen, though).
144 - large changes to make it partially compile and run on win32,
145 but win32 lacks too much functionality, and perl overrides way
146 too many functions with crashing versions.

212.33 Tue Jan 23 23:55:41 CET 2007 1482.33 Tue Jan 23 23:55:41 CET 2007
22 - fix install path (Andreas J. Koenig). 149 - fix install path (Andreas J. Koenig).
