92.5 Thu Oct 4 14:49:08 CEST 2007
10 - replaced _fd2fh with faster xs code.
11 - aio_close will now try to do "the right thing" and thus might
12 work sensibly for the very first time.
13
142.41 Mon Sep 24 21:28:21 CEST 2007
15 - after fork, invest some work to make sure that the poll_fileno
16 stays stable (by dup2'ing the new fd over the old one), to make
17 it easier for programs/libs that don't control their forking
18 behaviour and cannot recreate their watchers.
19
202.4 Sun Aug 5 18:44:22 CEST 2007
21 - add aio_truncate, aio_chmod, aio_chown, aio_utime (linux
22 successfully demonstrated that you can block on futimes...).
23 - allow undef as fileoffset for aio_read/write and use read/write(2)
24 internally (useful for sockets or O_APPEND handles).
25 - allow undef for length in aio_write.
26 - negative dataoffsets work as expected now in aio_read/aio_write.
27 - use NV instead of UV for 32 bit perls and file offsets, as NVs
28 have a larger range then.
29 - shared code between BDB and IO::AIO.
30 - aio_busy was completely broken. now fixed.
31 - readahead emulation now returns something.
32 - correctly set errno to ENOSYS on unimplemented functions
33 (should never happen, though).
34 - large changes to make it partially compile and run on win32,
35 but win32 lacks too much functionality, and perl overrides way
36 too many functions with crashing versions.
37
382.33 Tue Jan 23 23:55:41 CET 2007
39 - fix install path (Andreas J. Koenig).
40
412.32 Mon Jan 22 16:56:23 CET 2007
42 - added aio_rmtree.
43 - wow, aio_mkdir was missing.
44 - aio_load did return undef on error, not -1.
45 - use prefixexp not prefix in autoconf.pm
46 (suggested by ... rt.cpan.org unreachable).
47 - avoid installing autoconf.pm.
48
492.31 Sat Jan 6 03:46:02 CET 2007
50 - added aio_load.
51
522.3 Sat Dec 23 05:48:07 CET 2006
53 - fix off-by-one bug in aio_read, causing memory corruption
54 or crashes.
55
562.21 Fri Dec 22 05:03:38 CET 2006
57 - minor doc updates.
58 - minor cleanups.
59 - IO::AIO::poll returns request count.
60 - undocumented and unfinished async-signal-reporting.
61
622.2 Tue Oct 31 00:31:00 CET 2006
63 - minor doc updates.
64 - added aio_readlink.
65 - properly zero-terminate aio_read buffer.
66 - fix aio_read/write with nonzero dataoffset.
67 - reduced size of aio request structure.
68 - better diagnostics when pathnames etc. are not byte-encoded;
69 do not leak request in that case, either.
70
712.1 Sun Oct 29 02:01:57 CET 2006
72 - INCOMPATIBLE CHANGE: replace IO::AIO::poll_some by
73 IO::AIO::max_poll_reqs and IO::AIO::max_poll_time.
74 - fix a bug in aio_move where it would fail everytime
75 it would have to copy files manually.
76 - doc updates.
77 - start threads only on (very low) demand.
78 - end superfluous threads automatically after 10s idling.
79 - add IO::AIO::max_idle to control this.
80 - some tuning applied to random places.
81 - add aio_mknod.
82
832.0 Thu Oct 26 18:27:58 CEST 2006
84 - minor incompatibility: max_outstanding semantics have changed.
85 - major rewrite, consider all functionality EXPERIMENTAL.
86 - aio requests can be cancelled.
87 - callbacks can be (re-)set later.
88 - aio requests can choose between 9 priorities.
89 - add aio_group: aio requests can be grouped
90 into composite requests.
91 - generator interface for groups.
92 - add IO::AIO::poll_some.
93 - major documentation improvements.
94 - very minor bugfixes.
95 - add aio_nop for dummy requests.
96 - add aio_busy mainly for benchmarking and debugging.
97 - use "fast" mutexes on linux.
98 - use dynamic (and larger) buffers instead of
99 putting them onto the stack.
100 - optimise x86 and amd64 a bit.
101 - better error checking when ENOMEM.
102 - hopefully fix mem and dirp leaks on fork.
103 - warn about broken perl malloc.
104 - compiles on cygwin (but pread is broken on cygwin
105 which is not detected by autoconf, so you have to
106 edit autoconf/config.h yourself to enable emulation).
107
1081.8 Sat Jun 24 22:20:44 CEST 2006
109 - add and/or document aio_rename, aio_link, aio_symlink and aio_move.
110
1111.73 Wed Mar 1 22:49:32 CET 2006
112 - codename "jost"
113 - AIX/Solaris(?) aren't being helpful again, hardcode a value
114 for NAME_MAX and drive with your eyes closed (reported by
115 wcooley@nakedape.cc).
116
1171.72 Thu Feb 2 00:40:44 CET 2006
118 - another minor bug in aio_scandir, again, the callback was called
119 twice when the directory can't be stat'ed.
120
1211.71 Mon Dec 26 20:20:03 CET 2005
122 - grr, another minor bug in aio_scandir, this time resulting
123 in a runtime error.
124
1251.7 Mon Dec 26 19:29:48 CET 2005
126 - aio_scandir errornously called callback twice in some cases.
127 - added AnyEvent example.
128
1291.61 Wed Sep 7 19:40:42 CEST 2005
130 - no longer include $Config{libs}, as distros include too much
131 garbage in there that is not installed on typical systems
132 (for example, debian links perl against -lgdbm and many more
133 libraries despite perl not needing it, slowing down startup and
134 wasting memory).
135
1361.6 Tue Aug 30 17:44:44 CEST 2005
137 - added aio_readdir, aio_scandir.
138 - added aio_sendfile, including sendfile emulation when sendfile
139 isn't available. Linux, FreeBSD and HP-UX might work (sendfilev
140 support is unavailable on my solaris 8 machine, but preliminary
141 code is there. What's lacking is configury stuff and testing...).
142
1431.5 Sat Aug 20 02:32:19 CEST 2005
144 - create the aio threads on demand only (good after forking).
145 - somebody nagged about C89 compatibility, so this release should
146 be C89 compatible, but no guarantees for future ones.
147 - abort when the configure script fails.
148
1491.4 Wed Aug 17 08:07:27 CEST 2005
150 - forgot to recreate the pipe after forking, this could cause
151 deadlocks.
152
1531.3 Wed Aug 17 07:25:54 CEST 2005
4 - properly propagate exceptions from callbacks, instead of silently 154 - properly propagate exceptions from callbacks, instead of silently
5 eating them. 155 eating them.
6 - forking while in an atfork handler is now supported, although 156 - use a different fork algorithm that avoids recursive callback
7 I am pretty sure some pthread implementations will barf - don't 157 invocations and reduces fork latency in busy processes.
8 fork in an AIO callback if that is a concern for you, or synchronize 158 - fix a bug where the buffer scalar in aio_read got assigned the wrong
9 for yourself by clearing the request queue first. 159 length after reading.
160 - fix a bug where the child would process some outstanding requests
161 from the parent.
162 - make a copy of the callback scalar, to avoid some very uncommon
163 (but valid) usages where the callback scalar changes.
164 - the callback was never freed in aio_read/aio_write.
165 - aio_read/aio_write will now set the readonly flag on the data
166 scalar for better error reporting.
10 167
111.2 Wed Aug 17 01:22:58 CEST 2005 1681.2 Wed Aug 17 01:22:58 CEST 2005
12 - verified on cygwin, linux/amd64+ia32+alpha, solaris. 169 - verified on cygwin, linux/amd64+ia32+alpha, solaris.
13 - use SvPVbyte for filenames now. You *need* to encode your strings to 170 - use SvPVbyte for filenames now. You *need* to encode your strings to
14 the external filename encoding first. 171 the external filename encoding first.
