2 2
31.1 3TODO: better autoconf.pm that can return LIBS etc.
4TODO: aio_cptree/mvtree/rmtree
5TODO: aio_utime, aio_chmod, aio_chown? should simply stat/open first?

72.2 Tue Oct 31 00:31:00 CET 2006
8 - minor doc updates.
9 - added aio_readlink.
10 - properly zero-terminate aio_read buffer.
11 - fix aio_read/write with nonzero dataoffset.
12 - reduced size of aio request structure.
13 - better diagnostics when pathnames etc. are unicode-encoded,
14 do not leak request in that case, either.
15
162.1 Sun Oct 29 02:01:57 CET 2006
17 - INCOMPATIBLE CHANGE: replace IO::AIO::poll_some by
18 IO::AIO::max_poll_reqs and IO::AIO::max_poll_time.
19 - fix a bug in aio_move where it would fail everytime
20 it would have to copy files manually.
21 - doc updates.
22 - start threads only on (very low) demand.
23 - end superfluous threads automatically after 10s idling.
24 - add IO::AIO::max_idle to control this.
25 - some tuning applied to random places.
26 - add aio_mknod.
27
282.0 Thu Oct 26 18:27:58 CEST 2006
29 - minor incompatibility: max_outstanding semantics have changed.
30 - major rewrite, consider all functionality EXPERIMENTAL.
31 - aio requests can be cancelled.
32 - callbacks can be (re-)set later.
33 - aio requests can choose between 9 priorities.
34 - add aio_group: aio requests can be grouped
35 into composite requests.
36 - generator interface for groups.
37 - add IO::AIO::poll_some.
38 - major documentation improvements.
39 - very minor bugfixes.
40 - add aio_nop for dummy requests.
41 - add aio_busy mainly for benchmarking and debugging.
42 - use "fast" mutexes on linux.
43 - use dynamic (and larger) buffers instead of
44 putting them onto the stack.
45 - optimise x86 and amd64 a bit.
46 - better error checking when ENOMEM.
47 - hopefully fix mem and dirp leaks on fork.
48 - warn about broken perl malloc.
49 - compiles on cygwin (but pread is broken on cygwin
50 which is not detected by autoconf, so you have to
51 edit autoconf/config.h yourself to enable emulation).
52
531.8 Sat Jun 24 22:20:44 CEST 2006
54 - add and/or document aio_rename, aio_link, aio_symlink and aio_move.
55
561.73 Wed Mar 1 22:49:32 CET 2006
57 - codename "jost"
58 - AIX/Solaris(?) aren't being helpful again, hardcode a value
59 for NAME_MAX and drive with your eyes closed (reported by
60 wcooley@nakedape.cc).
61
621.72 Thu Feb 2 00:40:44 CET 2006
63 - another minor bug in aio_scandir, again, the callback was called
64 twice when the directory can't be stat'ed.
65
661.71 Mon Dec 26 20:20:03 CET 2005
67 - grr, another minor bug in aio_scandir, this time resulting
68 in a runtime error.
69
701.7 Mon Dec 26 19:29:48 CET 2005
71 - aio_scandir errornously called callback twice in some cases.
72 - added AnyEvent example.
73
741.61 Wed Sep 7 19:40:42 CEST 2005
75 - no longer include $Config{libs}, as distros include too much
76 garbage in there that is not installed on typical systems
77 (for example, debian links perl against -lgdbm and many more
78 libraries despite perl not needing it, slowing down startup and
79 wasting memory).
80
811.6 Tue Aug 30 17:44:44 CEST 2005
82 - added aio_readdir, aio_scandir.
83 - added aio_sendfile, including sendfile emulation when sendfile
84 isn't available. Linux, FreeBSD and HP-UX might work (sendfilev
85 support is unavailable on my solaris 8 machine, but preliminary
86 code is there. What's lacking is configury stuff and testing...).
87
881.5 Sat Aug 20 02:32:19 CEST 2005
89 - create the aio threads on demand only (good after forking).
90 - somebody nagged about C89 compatibility, so this release should
91 be C89 compatible, but no guarantees for future ones.
92 - abort when the configure script fails.
93
941.4 Wed Aug 17 08:07:27 CEST 2005
95 - forgot to recreate the pipe after forking, this could cause
96 deadlocks.
97
981.3 Wed Aug 17 07:25:54 CEST 2005
99 - properly propagate exceptions from callbacks, instead of silently
100 eating them.
101 - use a different fork algorithm that avoids recursive callback
102 invocations and reduces fork latency in busy processes.
103 - fix a bug where the buffer scalar in aio_read got assigned the wrong
104 length after reading.
105 - fix a bug where the child would process some outstanding requests
106 from the parent.
107 - make a copy of the callback scalar, to avoid some very uncommon
108 (but valid) usages where the callback scalar changes.
109 - the callback was never freed in aio_read/aio_write.
110 - aio_read/aio_write will now set the readonly flag on the data
111 scalar for better error reporting.
112
1131.2 Wed Aug 17 01:22:58 CEST 2005
114 - verified on cygwin, linux/amd64+ia32+alpha, solaris.
115 - use SvPVbyte for filenames now. You *need* to encode your strings to
116 the external filename encoding first.
117 - fix the bug where filehandles could leak (again).
118 - clarify freebsd situation: make it work and tell me how, or go away
119 with your underdocumented, broken and outdated OS.
120 - fork'ing should now be officially supported (where linux and
121 posix contradict each other, I followed posix).
122 - only call read() once per poll, not twice (speedup).
123 - new functions: aio_rmdir, aio_symlink.
124 - force callback arguments to be undef or a reference, for better
125 error catching.
126
1271.1 Sun Aug 7 05:27:23 CEST 2005
4 - added configure script to detetc availability of some calls. 128 - added configure script to detect availability of some calls.
129 (imperfect, as we cannot detect things like -lrt due to missing
130 feedback yet).
5 - emulate fdatasync by fsync, pread/pwrite by unsafe read/write 131 - emulate fdatasync via fsync, pread/pwrite via unsafe read/write
6 and readahead by manual reading on platforms lacking those. 132 and readahead via manual reading on platforms lacking those.
7 - ported t/03_errors.t+framework by Brad Fitzpatrick 133 - ported t/03_errors.t+framework by Brad Fitzpatrick
8 from Linux::AIO. 134 from Linux::AIO.
9 - removed XOPEN_SOURCE because stupid solaris 9 doesn't 135 - removed XOPEN_SOURCE because stupid solaris 9 doesn't
10 compile with it enabled. Probably breaks others. Oh well. 136 compile with it enabled. Probably breaks others. Oh well.
137 - try to be more careful with errno on non-threaded perls.
138 - cygwins perl insisted on a matching open mode when morphing
139 the fd to an fh.
140 - convert sv's to "byte" encoding in aio_read/aio_write. Might
141 do that for pathnames, too, in the future, so make sure you
142 properly encode your pathnames.

121.0 Fri Jul 22 10:43:30 CEST 2005 1441.0 Fri Jul 22 10:43:30 CEST 2005
13 - aio_open did not reliably deliver (open) filehandles. 145 - aio_open did not reliably deliver (open) filehandles.
14 - all aio_*-functions keep a reference to the filehandle so 146 - all aio_*-functions keep a reference to the filehandle so
15 it doesn't go away while the aio requests is working on it. 147 it doesn't go away while the aio requests is working on it.
