31.1 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

9 - added aio_rmtree.
10 - wow, aio_mkdir was missing.
11 - aio_load did return undef on error, not -1.
12
132.31 Sat Jan 6 03:46:02 CET 2007
14 - added aio_load.
15
162.3 Sat Dec 23 05:48:07 CET 2006
17 - fix off-by-one bug in aio_read, causing memory corruption
18 or crashes.
19
202.21 Fri Dec 22 05:03:38 CET 2006
21 - minor doc updates.
22 - minor cleanups.
23 - IO::AIO::poll returns request count.
24 - undocumented and unfinished async-signal-reporting.
25
262.2 Tue Oct 31 00:31:00 CET 2006
27 - minor doc updates.
28 - added aio_readlink.
29 - properly zero-terminate aio_read buffer.
30 - fix aio_read/write with nonzero dataoffset.
31 - reduced size of aio request structure.
32 - better diagnostics when pathnames etc. are not byte-encoded;
33 do not leak request in that case, either.
34
352.1 Sun Oct 29 02:01:57 CET 2006
36 - INCOMPATIBLE CHANGE: replace IO::AIO::poll_some by
37 IO::AIO::max_poll_reqs and IO::AIO::max_poll_time.
38 - fix a bug in aio_move where it would fail everytime
39 it would have to copy files manually.
40 - doc updates.
41 - start threads only on (very low) demand.
42 - end superfluous threads automatically after 10s idling.
43 - add IO::AIO::max_idle to control this.
44 - some tuning applied to random places.
45 - add aio_mknod.
46
472.0 Thu Oct 26 18:27:58 CEST 2006
48 - minor incompatibility: max_outstanding semantics have changed.
49 - major rewrite, consider all functionality EXPERIMENTAL.
50 - aio requests can be cancelled.
51 - callbacks can be (re-)set later.
52 - aio requests can choose between 9 priorities.
53 - add aio_group: aio requests can be grouped
54 into composite requests.
55 - generator interface for groups.
56 - add IO::AIO::poll_some.
57 - major documentation improvements.
58 - very minor bugfixes.
59 - add aio_nop for dummy requests.
60 - add aio_busy mainly for benchmarking and debugging.
61 - use "fast" mutexes on linux.
62 - use dynamic (and larger) buffers instead of
63 putting them onto the stack.
64 - optimise x86 and amd64 a bit.
65 - better error checking when ENOMEM.
66 - hopefully fix mem and dirp leaks on fork.
67 - warn about broken perl malloc.
68 - compiles on cygwin (but pread is broken on cygwin
69 which is not detected by autoconf, so you have to
70 edit autoconf/config.h yourself to enable emulation).
71
721.8 Sat Jun 24 22:20:44 CEST 2006
73 - add and/or document aio_rename, aio_link, aio_symlink and aio_move.
74
751.73 Wed Mar 1 22:49:32 CET 2006
76 - codename "jost"
77 - AIX/Solaris(?) aren't being helpful again, hardcode a value
78 for NAME_MAX and drive with your eyes closed (reported by
79 wcooley@nakedape.cc).
80
811.72 Thu Feb 2 00:40:44 CET 2006
82 - another minor bug in aio_scandir, again, the callback was called
83 twice when the directory can't be stat'ed.
84
851.71 Mon Dec 26 20:20:03 CET 2005
86 - grr, another minor bug in aio_scandir, this time resulting
87 in a runtime error.
88
891.7 Mon Dec 26 19:29:48 CET 2005
90 - aio_scandir errornously called callback twice in some cases.
91 - added AnyEvent example.
92
931.61 Wed Sep 7 19:40:42 CEST 2005
94 - no longer include $Config{libs}, as distros include too much
95 garbage in there that is not installed on typical systems
96 (for example, debian links perl against -lgdbm and many more
97 libraries despite perl not needing it, slowing down startup and
98 wasting memory).
99
1001.6 Tue Aug 30 17:44:44 CEST 2005
101 - added aio_readdir, aio_scandir.
102 - added aio_sendfile, including sendfile emulation when sendfile
103 isn't available. Linux, FreeBSD and HP-UX might work (sendfilev
104 support is unavailable on my solaris 8 machine, but preliminary
105 code is there. What's lacking is configury stuff and testing...).
106
1071.5 Sat Aug 20 02:32:19 CEST 2005
108 - create the aio threads on demand only (good after forking).
109 - somebody nagged about C89 compatibility, so this release should
110 be C89 compatible, but no guarantees for future ones.
111 - abort when the configure script fails.
112
1131.4 Wed Aug 17 08:07:27 CEST 2005
114 - forgot to recreate the pipe after forking, this could cause
115 deadlocks.
116
1171.3 Wed Aug 17 07:25:54 CEST 2005
118 - properly propagate exceptions from callbacks, instead of silently
119 eating them.
120 - use a different fork algorithm that avoids recursive callback
121 invocations and reduces fork latency in busy processes.
122 - fix a bug where the buffer scalar in aio_read got assigned the wrong
123 length after reading.
124 - fix a bug where the child would process some outstanding requests
125 from the parent.
126 - make a copy of the callback scalar, to avoid some very uncommon
127 (but valid) usages where the callback scalar changes.
128 - the callback was never freed in aio_read/aio_write.
129 - aio_read/aio_write will now set the readonly flag on the data
130 scalar for better error reporting.
131
1321.2 Wed Aug 17 01:22:58 CEST 2005
133 - verified on cygwin, linux/amd64+ia32+alpha, solaris.
134 - use SvPVbyte for filenames now. You *need* to encode your strings to
135 the external filename encoding first.
136 - fix the bug where filehandles could leak (again).
137 - clarify freebsd situation: make it work and tell me how, or go away
138 with your underdocumented, broken and outdated OS.
139 - fork'ing should now be officially supported (where linux and
140 posix contradict each other, I followed posix).
141 - only call read() once per poll, not twice (speedup).
142 - new functions: aio_rmdir, aio_symlink.
143 - force callback arguments to be undef or a reference, for better
144 error catching.
145
1461.1 Sun Aug 7 05:27:23 CEST 2005
4 - added configure script to detect availability of some calls. 147 - added configure script to detect availability of some calls.
5 (imperfect, as we cannot detect things like -lrt due it missing 148 (imperfect, as we cannot detect things like -lrt due to missing
6 feedback yet). 149 feedback yet).
7 - emulate fdatasync by fsync, pread/pwrite by unsafe read/write 150 - emulate fdatasync via fsync, pread/pwrite via unsafe read/write
8 and readahead by manual reading on platforms lacking those. 151 and readahead via manual reading on platforms lacking those.
9 - ported t/03_errors.t+framework by Brad Fitzpatrick 152 - ported t/03_errors.t+framework by Brad Fitzpatrick
10 from Linux::AIO. 153 from Linux::AIO.
11 - removed XOPEN_SOURCE because stupid solaris 9 doesn't 154 - removed XOPEN_SOURCE because stupid solaris 9 doesn't
12 compile with it enabled. Probably breaks others. Oh well. 155 compile with it enabled. Probably breaks others. Oh well.
13 - try to be more careful with errno on non-threaded perls. 156 - try to be more careful with errno on non-threaded perls.
157 - cygwins perl insisted on a matching open mode when morphing
158 the fd to an fh.
159 - convert sv's to "byte" encoding in aio_read/aio_write. Might
160 do that for pathnames, too, in the future, so make sure you
161 properly encode your pathnames.

151.0 Fri Jul 22 10:43:30 CEST 2005 1631.0 Fri Jul 22 10:43:30 CEST 2005
16 - aio_open did not reliably deliver (open) filehandles. 164 - aio_open did not reliably deliver (open) filehandles.
17 - all aio_*-functions keep a reference to the filehandle so 165 - all aio_*-functions keep a reference to the filehandle so
18 it doesn't go away while the aio requests is working on it. 166 it doesn't go away while the aio requests is working on it.
