6 8
72.0 9 - (libeio) correctly call pthread_attr_destroy ().
10
113.02 Mon May 12 02:32:02 CEST 2008
12 - fix a memory leak on aio_readlink.
13 - bring back working fchmod.
14 - nop and busy now set result to 0.
15 - set errno to ENOMEM when allocation fails.
16
173.01 Sun May 11 03:07:03 CEST 2008
18 - (libeio) make it compile on systems without readahead or readdir_r.
19 - (libeio) improve configure check for readahead availability.
20 - do not try to link against -lrt.
21 - use a separate configure script for IO::AIO (not the libeio one).
22
233.0 Sun May 11 00:57:14 CEST 2008
24 - added bin/treescan to the distribution.
25 - switched to using libeio.
26 - LOTS OF INCOMPATIBLE CHANGES:
27 - remove signal functionality, it is not worth the effort.
28 - max_outstanding no longer returns the previous number of requests.
29 - poll_cb no longer returns number of requests.
30
312.62 Sat Apr 26 13:59:33 CEST 2008
32 - port to solaris perls configured for old posix
33 (analysed by Jost Krieger).
34 - keep a reference to the perl filehandle object in aio_close,
35 so it doesn't get closed prematurely, leading to ugly races.
36
372.61 Wed Apr 16 18:45:02 CEST 2008
38 - fix treescan output duplication and improve output ordering.
39 also display files given on the commandline.
40 - use a different algorithm for aio_close that is faster
41 and probably has even lower chances of blocking.
42 - do our own stack memory management for threads - linux
43 allocates outrageous amounts of VM (not so bad unless you
44 use mlockall...), which severely limits the number of threads
45 on 32-bit arches: stack size is the larger of PTHREAD_STACK_MIN
46 and 4096 * sizeof (long) (usually this is 16..64k).
47
482.6 Sun Mar 30 08:28:11 CEST 2008
49 - added aio_sync.
50 - added aio_pathsync.
51 - fix prototypes of (void) functions.
52
532.51 Sat Oct 6 16:04:54 CEST 2007
54 - perlio isn't generally threadsafe, so aio_close could not work reliably.
55 aio_close now tries a safe hack that might not be that asynchronous
56 (see the manpage for details).
57 - discard callback return values as to not grow the stack endlessly
58 when poll_cb handles many requests without returning.
59 - minor code cleanups.
60
612.5 Thu Oct 4 14:49:08 CEST 2007
62 - replaced _fd2fh with faster xs code.
63 - aio_close will now try to do "the right thing" and thus might
64 work sensibly for the very first time.
65
662.41 Mon Sep 24 21:28:21 CEST 2007
67 - after fork, invest some work to make sure that the poll_fileno
68 stays stable (by dup2'ing the new fd over the old one), to make
69 it easier for programs/libs that don't control their forking
70 behaviour and cannot recreate their watchers.
71
722.4 Sun Aug 5 18:44:22 CEST 2007
73 - add aio_truncate, aio_chmod, aio_chown, aio_utime (linux
74 successfully demonstrated that you can block on futimes...).
75 - allow undef as fileoffset for aio_read/write and use read/write(2)
76 internally (useful for sockets or O_APPEND handles).
77 - allow undef for length in aio_write.
78 - negative dataoffsets work as expected now in aio_read/aio_write.
79 - use NV instead of UV for 32 bit perls and file offsets, as NVs
80 have a larger range then.
81 - shared code between BDB and IO::AIO.
82 - aio_busy was completely broken. now fixed.
83 - readahead emulation now returns something.
84 - correctly set errno to ENOSYS on unimplemented functions
85 (should never happen, though).
86 - large changes to make it partially compile and run on win32,
87 but win32 lacks too much functionality, and perl overrides way
88 too many functions with crashing versions.
89
902.33 Tue Jan 23 23:55:41 CET 2007
91 - fix install path (Andreas J. Koenig).
92
932.32 Mon Jan 22 16:56:23 CET 2007
94 - added aio_rmtree.
95 - wow, aio_mkdir was missing.
96 - aio_load did return undef on error, not -1.
97 - use prefixexp not prefix in autoconf.pm
98 (suggested by ... rt.cpan.org unreachable).
99 - avoid installing autoconf.pm.
100
1012.31 Sat Jan 6 03:46:02 CET 2007
102 - added aio_load.
103
1042.3 Sat Dec 23 05:48:07 CET 2006
105 - fix off-by-one bug in aio_read, causing memory corruption
106 or crashes.
107
1082.21 Fri Dec 22 05:03:38 CET 2006
109 - minor doc updates.
110 - minor cleanups.
111 - IO::AIO::poll returns request count.

113
1142.2 Tue Oct 31 00:31:00 CET 2006
115 - minor doc updates.
116 - added aio_readlink.
117 - properly zero-terminate aio_read buffer.
118 - fix aio_read/write with nonzero dataoffset.
119 - reduced size of aio request structure.
120 - better diagnostics when pathnames etc. are not byte-encoded;
121 do not leak request in that case, either.
122
1232.1 Sun Oct 29 02:01:57 CET 2006
124 - INCOMPATIBLE CHANGE: replace IO::AIO::poll_some by
125 IO::AIO::max_poll_reqs and IO::AIO::max_poll_time.
126 - fix a bug in aio_move where it would fail everytime
127 it would have to copy files manually.
128 - doc updates.
129 - start threads only on (very low) demand.
130 - end superfluous threads automatically after 10s idling.
131 - add IO::AIO::max_idle to control this.
132 - some tuning applied to random places.
133 - add aio_mknod.
134
1352.0 Thu Oct 26 18:27:58 CEST 2006
136 - minor incompatibility: max_outstanding semantics have changed.
137 - major rewrite, consider all functionality EXPERIMENTAL.
8 - aio requests can be cancelled. 138 - aio requests can be cancelled.
139 - callbacks can be (re-)set later.
140 - aio requests can choose between 9 priorities.
9 - add aio_group: aio requests can be grouped. 141 - add aio_group: aio requests can be grouped
142 into composite requests.
10 - implement generator interface for groups. 143 - generator interface for groups.
144 - add IO::AIO::poll_some.
11 - major documentation improvements. 145 - major documentation improvements.
12 - very minor bugfixes. 146 - very minor bugfixes.
13 - add aio_nop for dummy requests. 147 - add aio_nop for dummy requests.
14 - add aio_sleep mainly for benchmarking and debugging. 148 - add aio_busy mainly for benchmarking and debugging.
15 - deprecated max_outstanding. 149 - use "fast" mutexes on linux.
150 - use dynamic (and larger) buffers instead of
151 putting them onto the stack.
152 - optimise x86 and amd64 a bit.
153 - better error checking when ENOMEM.
154 - hopefully fix mem and dirp leaks on fork.
155 - warn about broken perl malloc.
156 - compiles on cygwin (but pread is broken on cygwin
157 which is not detected by autoconf, so you have to
158 edit autoconf/config.h yourself to enable emulation).

171.8 Sat Jun 24 22:20:44 CEST 2006 1601.8 Sat Jun 24 22:20:44 CEST 2006
