10 - after fork, invest some work to make sure that the poll_fileno
11 stays stable (by dup2'ing the new fd over the old one), to make
12 it easier for programs/libs that don't control their forking
13 behaviour and cannot recreate their watchers.
14
152.4 Sun Aug 5 18:44:22 CEST 2007
16 - add aio_truncate, aio_chmod, aio_chown, aio_utime (linux
17 successfully demonstrated that you can block on futimes...).
18 - allow undef as fileoffset for aio_read/write and use read/write(2)
19 internally (useful for sockets or O_APPEND handles).
20 - allow undef for length in aio_write.
21 - negative dataoffsets work as expected now in aio_read/aio_write.
22 - use NV instead of UV for 32 bit perls and file offsets, as NVs
23 have a larger range then.
24 - shared code between BDB and IO::AIO.
25 - aio_busy was completely broken. now fixed.
26 - readahead emulation now returns something.
27 - correctly set errno to ENOSYS on unimplemented functions
28 (should never happen, though).
29 - large changes to make it partially compile and run on win32,
30 but win32 lacks too much functionality, and perl overrides way
31 too many functions with crashing versions.
32
332.33 Tue Jan 23 23:55:41 CET 2007
34 - fix install path (Andreas J. Koenig).
35
362.32 Mon Jan 22 16:56:23 CET 2007
37 - added aio_rmtree.
38 - wow, aio_mkdir was missing.
39 - aio_load did return undef on error, not -1.
40 - use prefixexp not prefix in autoconf.pm
41 (suggested by ... rt.cpan.org unreachable).
42 - avoid installing autoconf.pm.
43
442.31 Sat Jan 6 03:46:02 CET 2007
45 - added aio_load.
46
472.3 Sat Dec 23 05:48:07 CET 2006
48 - fix off-by-one bug in aio_read, causing memory corruption
49 or crashes.
50
512.21 Fri Dec 22 05:03:38 CET 2006
52 - minor doc updates.
53 - minor cleanups.
54 - IO::AIO::poll returns request count.
55 - undocumented and unfinished async-signal-reporting.
56
572.2 Tue Oct 31 00:31:00 CET 2006
58 - minor doc updates.
59 - added aio_readlink.
60 - properly zero-terminate aio_read buffer.
61 - fix aio_read/write with nonzero dataoffset.
62 - reduced size of aio request structure.
63 - better diagnostics when pathnames etc. are not byte-encoded;
64 do not leak request in that case, either.
65
662.1 Sun Oct 29 02:01:57 CET 2006
67 - INCOMPATIBLE CHANGE: replace IO::AIO::poll_some by
68 IO::AIO::max_poll_reqs and IO::AIO::max_poll_time.
69 - fix a bug in aio_move where it would fail everytime
70 it would have to copy files manually.
71 - doc updates.
72 - start threads only on (very low) demand.
73 - end superfluous threads automatically after 10s idling.
74 - add IO::AIO::max_idle to control this.
75 - some tuning applied to random places.
76 - add aio_mknod.
77
782.0 Thu Oct 26 18:27:58 CEST 2006
79 - minor incompatibility: max_outstanding semantics have changed.
80 - major rewrite, consider all functionality EXPERIMENTAL.
81 - aio requests can be cancelled.
82 - callbacks can be (re-)set later.
83 - aio requests can choose between 9 priorities.
84 - add aio_group: aio requests can be grouped
85 into composite requests.
86 - generator interface for groups.
87 - add IO::AIO::poll_some.
88 - major documentation improvements.
89 - very minor bugfixes.
90 - add aio_nop for dummy requests.
91 - add aio_busy mainly for benchmarking and debugging.
92 - use "fast" mutexes on linux.
93 - use dynamic (and larger) buffers instead of
94 putting them onto the stack.
95 - optimise x86 and amd64 a bit.
96 - better error checking when ENOMEM.
97 - hopefully fix mem and dirp leaks on fork.
98 - warn about broken perl malloc.
99 - compiles on cygwin (but pread is broken on cygwin
100 which is not detected by autoconf, so you have to
101 edit autoconf/config.h yourself to enable emulation).
102
1031.8 Sat Jun 24 22:20:44 CEST 2006
104 - add and/or document aio_rename, aio_link, aio_symlink and aio_move.
105
1061.73 Wed Mar 1 22:49:32 CET 2006
107 - codename "jost"
108 - AIX/Solaris(?) aren't being helpful again, hardcode a value
109 for NAME_MAX and drive with your eyes closed (reported by
110 wcooley@nakedape.cc).
111
1121.72 Thu Feb 2 00:40:44 CET 2006
113 - another minor bug in aio_scandir, again, the callback was called
114 twice when the directory can't be stat'ed.
115
1161.71 Mon Dec 26 20:20:03 CET 2005
117 - grr, another minor bug in aio_scandir, this time resulting
118 in a runtime error.
119
1201.7 Mon Dec 26 19:29:48 CET 2005
121 - aio_scandir errornously called callback twice in some cases.
122 - added AnyEvent example.
123
1241.61 Wed Sep 7 19:40:42 CEST 2005
125 - no longer include $Config{libs}, as distros include too much
126 garbage in there that is not installed on typical systems
127 (for example, debian links perl against -lgdbm and many more
128 libraries despite perl not needing it, slowing down startup and
129 wasting memory).
130
1311.6 Tue Aug 30 17:44:44 CEST 2005
132 - added aio_readdir, aio_scandir.
133 - added aio_sendfile, including sendfile emulation when sendfile
134 isn't available. Linux, FreeBSD and HP-UX might work (sendfilev
135 support is unavailable on my solaris 8 machine, but preliminary
136 code is there. What's lacking is configury stuff and testing...).
137
1381.5 Sat Aug 20 02:32:19 CEST 2005
139 - create the aio threads on demand only (good after forking).
140 - somebody nagged about C89 compatibility, so this release should
141 be C89 compatible, but no guarantees for future ones.
142 - abort when the configure script fails.
143
1441.4 Wed Aug 17 08:07:27 CEST 2005
145 - forgot to recreate the pipe after forking, this could cause
146 deadlocks.
147
1481.3 Wed Aug 17 07:25:54 CEST 2005
4 - properly propagate exceptions from callbacks, instead of silently 149 - properly propagate exceptions from callbacks, instead of silently
5 eating them. 150 eating them.
6 - forking while in an atfork handler is now supported, although 151 - use a different fork algorithm that avoids recursive callback
7 I am pretty sure some pthread implementations will barf - don't 152 invocations and reduces fork latency in busy processes.
8 fork in an AIO callback if that is a concern for you, or synchronize 153 - fix a bug where the buffer scalar in aio_read got assigned the wrong
9 for yourself by clearing the request queue first. 154 length after reading.
155 - fix a bug where the child would process some outstanding requests
156 from the parent.
157 - make a copy of the callback scalar, to avoid some very uncommon
158 (but valid) usages where the callback scalar changes.
159 - the callback was never freed in aio_read/aio_write.
160 - aio_read/aio_write will now set the readonly flag on the data
161 scalar for better error reporting.
10 162
111.2 Wed Aug 17 01:22:58 CEST 2005 1631.2 Wed Aug 17 01:22:58 CEST 2005
12 - verified on cygwin, linux/amd64+ia32+alpha, solaris. 164 - verified on cygwin, linux/amd64+ia32+alpha, solaris.
13 - use SvPVbyte for filenames now. You *need* to encode your strings to 165 - use SvPVbyte for filenames now. You *need* to encode your strings to
14 the external filename encoding first. 166 the external filename encoding first.
