3TODO: better autoconf.pm that can return LIBS etc.
4TODO: aio_cptree/mvtree
5TODO: aio_utime, aio_chmod, aio_chown? should simply stat/open first?
6TODO: reduce condvar fairness: schedule hot-cache-threads first?
7TODO: fix setsig

92.4
10 - shared code between BDB and IO::AIO.
11 - fix aio_busy w.r.t. fractional delays.
12 - add aio_chmod, aio_chown, aio_utime.
13 - correctly set errno to ENOSYS on unimplemented functions
14 (should never happen, though).
15
162.33 Tue Jan 23 23:55:41 CET 2007
17 - fix install path (Andreas J. Koenig).
18
192.32 Mon Jan 22 16:56:23 CET 2007
20 - added aio_rmtree.
21 - wow, aio_mkdir was missing.
22 - aio_load did return undef on error, not -1.
23 - use prefixexp not prefix in autoconf.pm
24 (suggested by ... rt.cpan.org unreachable).
25 - avoid installing autoconf.pm.
26
272.31 Sat Jan 6 03:46:02 CET 2007
28 - added aio_load.
29
302.3 Sat Dec 23 05:48:07 CET 2006
31 - fix off-by-one bug in aio_read, causing memory corruption
32 or crashes.
33
342.21 Fri Dec 22 05:03:38 CET 2006
35 - minor doc updates.
36 - minor cleanups.
37 - IO::AIO::poll returns request count.
38 - undocumented and unfinished async-signal-reporting.
39
402.2 Tue Oct 31 00:31:00 CET 2006
41 - minor doc updates.
42 - added aio_readlink.
43 - properly zero-terminate aio_read buffer.
44 - fix aio_read/write with nonzero dataoffset.
45 - reduced size of aio request structure.
46 - better diagnostics when pathnames etc. are not byte-encoded;
47 do not leak request in that case, either.
48
492.1 Sun Oct 29 02:01:57 CET 2006
50 - INCOMPATIBLE CHANGE: replace IO::AIO::poll_some by
51 IO::AIO::max_poll_reqs and IO::AIO::max_poll_time.
52 - fix a bug in aio_move where it would fail everytime
53 it would have to copy files manually.
54 - doc updates.
55 - start threads only on (very low) demand.
56 - end superfluous threads automatically after 10s idling.
57 - add IO::AIO::max_idle to control this.
58 - some tuning applied to random places.
59 - add aio_mknod.
60
612.0 Thu Oct 26 18:27:58 CEST 2006
62 - minor incompatibility: max_outstanding semantics have changed.
63 - major rewrite, consider all functionality EXPERIMENTAL.
64 - aio requests can be cancelled.
65 - callbacks can be (re-)set later.
66 - aio requests can choose between 9 priorities.
67 - add aio_group: aio requests can be grouped
68 into composite requests.
69 - generator interface for groups.
70 - add IO::AIO::poll_some.
71 - major documentation improvements.
72 - very minor bugfixes.
73 - add aio_nop for dummy requests.
74 - add aio_busy mainly for benchmarking and debugging.
75 - use "fast" mutexes on linux.
76 - use dynamic (and larger) buffers instead of
77 putting them onto the stack.
78 - optimise x86 and amd64 a bit.
79 - better error checking when ENOMEM.
80 - hopefully fix mem and dirp leaks on fork.
81 - warn about broken perl malloc.
82 - compiles on cygwin (but pread is broken on cygwin
83 which is not detected by autoconf, so you have to
84 edit autoconf/config.h yourself to enable emulation).
85
861.8 Sat Jun 24 22:20:44 CEST 2006
87 - add and/or document aio_rename, aio_link, aio_symlink and aio_move.
88
891.73 Wed Mar 1 22:49:32 CET 2006
90 - codename "jost"
91 - AIX/Solaris(?) aren't being helpful again, hardcode a value
92 for NAME_MAX and drive with your eyes closed (reported by
93 wcooley@nakedape.cc).
94
951.72 Thu Feb 2 00:40:44 CET 2006
96 - another minor bug in aio_scandir, again, the callback was called
97 twice when the directory can't be stat'ed.
98
991.71 Mon Dec 26 20:20:03 CET 2005
100 - grr, another minor bug in aio_scandir, this time resulting
101 in a runtime error.
102
1031.7 Mon Dec 26 19:29:48 CET 2005
104 - aio_scandir errornously called callback twice in some cases.
105 - added AnyEvent example.
106
1071.61 Wed Sep 7 19:40:42 CEST 2005
108 - no longer include $Config{libs}, as distros include too much
109 garbage in there that is not installed on typical systems
110 (for example, debian links perl against -lgdbm and many more
111 libraries despite perl not needing it, slowing down startup and
112 wasting memory).
113
1141.6 Tue Aug 30 17:44:44 CEST 2005
115 - added aio_readdir, aio_scandir.
116 - added aio_sendfile, including sendfile emulation when sendfile
117 isn't available. Linux, FreeBSD and HP-UX might work (sendfilev
118 support is unavailable on my solaris 8 machine, but preliminary
119 code is there. What's lacking is configury stuff and testing...).
120
1211.5 Sat Aug 20 02:32:19 CEST 2005
122 - create the aio threads on demand only (good after forking).
123 - somebody nagged about C89 compatibility, so this release should
124 be C89 compatible, but no guarantees for future ones.
125 - abort when the configure script fails.
126
1271.4 Wed Aug 17 08:07:27 CEST 2005
128 - forgot to recreate the pipe after forking, this could cause
129 deadlocks.
130
1311.3 Wed Aug 17 07:25:54 CEST 2005
132 - properly propagate exceptions from callbacks, instead of silently
133 eating them.
134 - use a different fork algorithm that avoids recursive callback
135 invocations and reduces fork latency in busy processes.
136 - fix a bug where the buffer scalar in aio_read got assigned the wrong
137 length after reading.
138 - fix a bug where the child would process some outstanding requests
139 from the parent.
140 - make a copy of the callback scalar, to avoid some very uncommon
141 (but valid) usages where the callback scalar changes.
142 - the callback was never freed in aio_read/aio_write.
143 - aio_read/aio_write will now set the readonly flag on the data
144 scalar for better error reporting.
145
1461.2 Wed Aug 17 01:22:58 CEST 2005
147 - verified on cygwin, linux/amd64+ia32+alpha, solaris.
148 - use SvPVbyte for filenames now. You *need* to encode your strings to
149 the external filename encoding first.
150 - fix the bug where filehandles could leak (again).
151 - clarify freebsd situation: make it work and tell me how, or go away
152 with your underdocumented, broken and outdated OS.
153 - fork'ing should now be officially supported (where linux and
154 posix contradict each other, I followed posix).
155 - only call read() once per poll, not twice (speedup).
156 - new functions: aio_rmdir, aio_symlink.
157 - force callback arguments to be undef or a reference, for better
158 error catching.
159
1601.1 Sun Aug 7 05:27:23 CEST 2005
161 - added configure script to detect availability of some calls.
162 (imperfect, as we cannot detect things like -lrt due to missing
163 feedback yet).
164 - emulate fdatasync via fsync, pread/pwrite via unsafe read/write
165 and readahead via manual reading on platforms lacking those.
3 - ported t/03_errors.t+framework by Brad Fitzpatrick 166 - ported t/03_errors.t+framework by Brad Fitzpatrick
4 from Linux::AIO. 167 from Linux::AIO.
5 - removed XOPEN_SOURCE because stupid solaris 9 doesn't 168 - removed XOPEN_SOURCE because stupid solaris 9 doesn't
6 compile with it enabled. Probably breaks others. Oh well. 169 compile with it enabled. Probably breaks others. Oh well.
170 - try to be more careful with errno on non-threaded perls.
171 - cygwins perl insisted on a matching open mode when morphing
172 the fd to an fh.
173 - convert sv's to "byte" encoding in aio_read/aio_write. Might
174 do that for pathnames, too, in the future, so make sure you
175 properly encode your pathnames.
7 176
81.0 Fri Jul 22 10:43:30 CEST 2005 1771.0 Fri Jul 22 10:43:30 CEST 2005
9 - aio_open did not reliably deliver (open) filehandles. 178 - aio_open did not reliably deliver (open) filehandles.
10 - all aio_*-functions keep a reference to the filehandle so 179 - all aio_*-functions keep a reference to the filehandle so
11 it doesn't go away while the aio requests is working on it. 180 it doesn't go away while the aio requests is working on it.
