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 - use prefixexp not prefix in autoconf.pm
13 (suggested by ... rt.cpan.org unreachable).
14
152.31 Sat Jan 6 03:46:02 CET 2007
16 - added aio_load.
17
182.3 Sat Dec 23 05:48:07 CET 2006
19 - fix off-by-one bug in aio_read, causing memory corruption
20 or crashes.
21
222.21 Fri Dec 22 05:03:38 CET 2006
23 - minor doc updates.
24 - minor cleanups.
25 - IO::AIO::poll returns request count.
26 - undocumented and unfinished async-signal-reporting.
27
282.2 Tue Oct 31 00:31:00 CET 2006
29 - minor doc updates.
30 - added aio_readlink.
31 - properly zero-terminate aio_read buffer.
32 - fix aio_read/write with nonzero dataoffset.
33 - reduced size of aio request structure.
34 - better diagnostics when pathnames etc. are not byte-encoded;
35 do not leak request in that case, either.
36
372.1 Sun Oct 29 02:01:57 CET 2006
38 - INCOMPATIBLE CHANGE: replace IO::AIO::poll_some by
39 IO::AIO::max_poll_reqs and IO::AIO::max_poll_time.
40 - fix a bug in aio_move where it would fail everytime
41 it would have to copy files manually.
42 - doc updates.
43 - start threads only on (very low) demand.
44 - end superfluous threads automatically after 10s idling.
45 - add IO::AIO::max_idle to control this.
46 - some tuning applied to random places.
47 - add aio_mknod.
48
492.0 Thu Oct 26 18:27:58 CEST 2006
50 - minor incompatibility: max_outstanding semantics have changed.
51 - major rewrite, consider all functionality EXPERIMENTAL.
52 - aio requests can be cancelled.
53 - callbacks can be (re-)set later.
54 - aio requests can choose between 9 priorities.
55 - add aio_group: aio requests can be grouped
56 into composite requests.
57 - generator interface for groups.
58 - add IO::AIO::poll_some.
59 - major documentation improvements.
60 - very minor bugfixes.
61 - add aio_nop for dummy requests.
62 - add aio_busy mainly for benchmarking and debugging.
63 - use "fast" mutexes on linux.
64 - use dynamic (and larger) buffers instead of
65 putting them onto the stack.
66 - optimise x86 and amd64 a bit.
67 - better error checking when ENOMEM.
68 - hopefully fix mem and dirp leaks on fork.
69 - warn about broken perl malloc.
70 - compiles on cygwin (but pread is broken on cygwin
71 which is not detected by autoconf, so you have to
72 edit autoconf/config.h yourself to enable emulation).
73
741.8 Sat Jun 24 22:20:44 CEST 2006
75 - add and/or document aio_rename, aio_link, aio_symlink and aio_move.
76
771.73 Wed Mar 1 22:49:32 CET 2006
78 - codename "jost"
79 - AIX/Solaris(?) aren't being helpful again, hardcode a value
80 for NAME_MAX and drive with your eyes closed (reported by
81 wcooley@nakedape.cc).
82
831.72 Thu Feb 2 00:40:44 CET 2006
84 - another minor bug in aio_scandir, again, the callback was called
85 twice when the directory can't be stat'ed.
86
871.71 Mon Dec 26 20:20:03 CET 2005
88 - grr, another minor bug in aio_scandir, this time resulting
89 in a runtime error.
90
911.7 Mon Dec 26 19:29:48 CET 2005
92 - aio_scandir errornously called callback twice in some cases.
93 - added AnyEvent example.
94
951.61 Wed Sep 7 19:40:42 CEST 2005
96 - no longer include $Config{libs}, as distros include too much
97 garbage in there that is not installed on typical systems
98 (for example, debian links perl against -lgdbm and many more
99 libraries despite perl not needing it, slowing down startup and
100 wasting memory).
101
1021.6 Tue Aug 30 17:44:44 CEST 2005
103 - added aio_readdir, aio_scandir.
104 - added aio_sendfile, including sendfile emulation when sendfile
105 isn't available. Linux, FreeBSD and HP-UX might work (sendfilev
106 support is unavailable on my solaris 8 machine, but preliminary
107 code is there. What's lacking is configury stuff and testing...).
108
1091.5 Sat Aug 20 02:32:19 CEST 2005
110 - create the aio threads on demand only (good after forking).
111 - somebody nagged about C89 compatibility, so this release should
112 be C89 compatible, but no guarantees for future ones.
113 - abort when the configure script fails.
114
1151.4 Wed Aug 17 08:07:27 CEST 2005
116 - forgot to recreate the pipe after forking, this could cause
117 deadlocks.
118
1191.3 Wed Aug 17 07:25:54 CEST 2005
120 - properly propagate exceptions from callbacks, instead of silently
121 eating them.
122 - use a different fork algorithm that avoids recursive callback
123 invocations and reduces fork latency in busy processes.
124 - fix a bug where the buffer scalar in aio_read got assigned the wrong
125 length after reading.
126 - fix a bug where the child would process some outstanding requests
127 from the parent.
128 - make a copy of the callback scalar, to avoid some very uncommon
129 (but valid) usages where the callback scalar changes.
130 - the callback was never freed in aio_read/aio_write.
131 - aio_read/aio_write will now set the readonly flag on the data
132 scalar for better error reporting.
133
1341.2 Wed Aug 17 01:22:58 CEST 2005
135 - verified on cygwin, linux/amd64+ia32+alpha, solaris.
136 - use SvPVbyte for filenames now. You *need* to encode your strings to
137 the external filename encoding first.
138 - fix the bug where filehandles could leak (again).
139 - clarify freebsd situation: make it work and tell me how, or go away
140 with your underdocumented, broken and outdated OS.
141 - fork'ing should now be officially supported (where linux and
142 posix contradict each other, I followed posix).
143 - only call read() once per poll, not twice (speedup).
144 - new functions: aio_rmdir, aio_symlink.
145 - force callback arguments to be undef or a reference, for better
146 error catching.
147
1481.1 Sun Aug 7 05:27:23 CEST 2005
4 - added configure script to detetc availability of some calls. 149 - added configure script to detect availability of some calls.
150 (imperfect, as we cannot detect things like -lrt due to missing
151 feedback yet).
5 - emulate fdatasync by fsync, pread/pwrite by unsafe read/write 152 - emulate fdatasync via fsync, pread/pwrite via unsafe read/write
6 and readahead by manual reading on platforms lacking those. 153 and readahead via manual reading on platforms lacking those.
7 - ported t/03_errors.t+framework by Brad Fitzpatrick 154 - ported t/03_errors.t+framework by Brad Fitzpatrick
8 from Linux::AIO. 155 from Linux::AIO.
9 - removed XOPEN_SOURCE because stupid solaris 9 doesn't 156 - removed XOPEN_SOURCE because stupid solaris 9 doesn't
10 compile with it enabled. Probably breaks others. Oh well. 157 compile with it enabled. Probably breaks others. Oh well.
158 - try to be more careful with errno on non-threaded perls.
159 - cygwins perl insisted on a matching open mode when morphing
160 the fd to an fh.
161 - convert sv's to "byte" encoding in aio_read/aio_write. Might
162 do that for pathnames, too, in the future, so make sure you
163 properly encode your pathnames.
11 164
121.0 Fri Jul 22 10:43:30 CEST 2005 1651.0 Fri Jul 22 10:43:30 CEST 2005
13 - aio_open did not reliably deliver (open) filehandles. 166 - aio_open did not reliably deliver (open) filehandles.
14 - all aio_*-functions keep a reference to the filehandle so 167 - all aio_*-functions keep a reference to the filehandle so
15 it doesn't go away while the aio requests is working on it. 168 it doesn't go away while the aio requests is working on it.
