133.8 Sun Mar 27 12:25:33 CEST 2011
14 - use nonstandard but maybe-working-on-bsd fork technique.
15 - support a max_idle value of 0.
16 - support setting of idle timeout value (IO::AIO::idle_timeout).
17
183.72 Fri Feb 11 04:25:38 CET 2011
19 - use _POSIX_MEMLOCK_RANGE to detect mlock/munlock.
20 - aio_mknod always used a dev_t value of 0.
21 - new treescan option: --grep.
22 - add more S_IF macros, and major/minor/makedev "macros".
23
243.71 Thu Dec 30 08:18:46 CET 2010
25 - the numerical result value passed to callbacks did not stringify
26 correctly, due to internal reuse and failure to reset the sv flags.
27 - actually test for posix_[mf]advise, as at least uClibc defines
28 _POSIX_ADVISORY_INFO without actually having any of the required
29 funcitonality. ugh.
30
313.7 Mon Nov 1 23:00:34 CET 2010
32 - implement/add madvise, mmap, munmap, aio_mlockall, munlockall,
33 aio_mlock, munlock, msync and mtouch to @EXPORT_OK.
34 - document the sad state of affairs w.r.t. pthread on many bsds.
35 - do not enable mmap on systems without _POSIX_MAPPED_FILES
36 (openbsd 4.8).
37 - do not leak memory in IO::AIO::mmap when the scalar already
38 had string-data.
39 - add O_RDWR, O_APPEND and O_EXCL symbols and semi-document
40 them.
41 - cache the result IV, for a minor speedup in the common case.
42 - croak when an mmapped-scalar changes location, to detect
43 user-errors better.
44 - fix aio_readlink prototype.
45
463.65 Wed Mar 31 02:45:05 CEST 2010
47 - actually use PATH_MAX instead of NAME_MAX for readlink, as to not
48 cut off long pathnames in aio_readlink (based on patch by
49 Rasmus Andersson).
50 - a double fork partially killed the event pipe (great testcase
51 by dormando). affects IO::AIO, BDB and Async::Interrupt.
52 - suck steve's dick and rename our symbols to avoid colliding
53 with nonstandard identifier spam on the broken os x pseudo-os.
54 affects IO::AIO and BDB.
55
563.6 Mon Jan 11 00:43:39 CET 2010
57 - (libeio) more fixes for the freebsd/apple sendfile - broken by
58 manpage standards, but apparently correct accoridng to actual
59 kernel sources.
60 - add IO::AIO::mmap/munmap support.
61 - add IO::AIO::m(un)lockall support.
62 - clean up manpage.
63
643.5 Thu Jan 7 21:25:04 CET 2010
65 - (liebio) fix freebsd sendfile (Vanilla Hsu).
66 - (libeio) also fix darwin sendfile that suffered from a similar bug.
67 - add aio_statvfs as interface to statvfs/fstatvfs.
68 - work around buggy symlink() on cygwin in the testsuite.
69 - wtf. freebsd-8.0 actually passes the testsuite! I knew
70 they could implement fork and semaphores one day! cheers!
71
723.4 Sat Jan 2 15:13:04 CET 2010
73 - (libeio) max_poll_time was not properly converted to ticks.
74 - clarify cancel_subs description.
75 - IO::AIO::sendfile did not actually return the return value
76 from the sendfile call.
77 - implement aio_msync, aio_mtouch.
78 - (libeio) tentatively support darwin in sendfile.
79
803.31 Thu Nov 12 02:14:29 CET 2009
81 - fix result status documentation of aio_copy, aio_move.
82 - speed up object creation considerably by avoiding
83 hash lookups.
84
853.3 Wed Aug 5 13:52:58 CEST 2009
86 - use common::sense.
87 - use common schmorp.h header.
88 - allow integers (file descriptors) in addition to file handles.
89 - take advantage of linux' eventfd (but it seems slower on smp?).
90 - use poll not select on posix platforms.
91
923.261 Wed Jul 1 10:11:51 CEST 2009
93 - more 0S X workarounds (patch by Tokuhiro Matsuno).
94
953.26 Tue Jun 30 09:33:26 CEST 2009
96 - 0S X of course claims to be posix 2008 but lacks posix_fadvise.
97 try to work around this horribly broken OS in a somewhat hackish
98 way. might help other os's too.
99
1003.25 Sat Jun 27 05:18:26 CEST 2009
101 - added IO::AIO::fadvise and IO::AIO::sendfile.
102 - (libeio) replaced quicksort+insertion sort by a tuned radix
103 sort + insertion sort, resulting in comparable runtime (usually
104 faster) to the old version, but without any ill side effects on
105 degenerated (for quicksort) data.
106 - (libeio) correctly sort dirs by inodes if we have perfect type
107 knowledge and DIRS_FIRST is used.
108 - (libeio) internally the wrong DT_* constants were used, but no
109 known system has differing EIO_DT_*/DT_* values, so not an issue.
110 - removed a (harmless) assert that was left over on the code
111 but should not have been.
112 - use more correct types (change IO length from IV to VAL64,
113 which makes a difference on systems without 64 bit perls).
114
1153.23 Sat Jun 13 16:57:58 CEST 2009
116 - fix off-by-one bug in aio_readdir that was introduced in the
117 rushed 3.22 release.
118
1193.22 Sat Jun 13 15:32:40 CEST 2009
120 - speed up readdirx sort algorithm slightly.
121 - bin/treescan was missing from distro tarball.
122
1233.21 Fri Jun 12 18:45:53 CEST 2009
124 - new options --dirs and --files for treescan.
125 - install bin/treescan by default.
126 - (libeio) aio_readdir can now be cancelled while executing.
127 - fix a printf format string for 64 bit systems (could lead
128 to problems on big endian 64 bit systems).
129 - do not use qsort() but our own algorithm: glibc initialises
130 the whole locale and I/O subsystem inside qsort, causing
131 a stack overflow on 32 bit machines. The new sort uses much less
132 stack and is more than twice as fast in typical situations.
133
1343.2 Sun Jun 7 20:30:05 CEST 2009
135 - (libeio) pwrite emulation was even more flawed than intended and did
136 not restore the file offset.
137 - add aio_readdirx, which can return inode and filetype and sort
138 the names in various ways.
139 - unfortunately, utime, chmod, chown on an open file that has just
140 been written can easily block, which caused aio_copy to block the
141 process. no more!
142 - no longer rely on dst path in aio_copy when futime is available.
143
1443.19 Tue Apr 21 22:05:21 CEST 2009
145 - more perl 5.10 workarounds for aio_read and write.
146 - aio_write no longer modifies the sv (if possible).
147 - aio_read now works correctly with magic values.
148
1493.18 Sun Apr 19 21:17:32 CEST 2009
150 - better diagnostics when some aio_* functions get passed an illegal fh.
151 - try to avoid crashes due to incompatible 5.10 API changes. grmbl.
152
1533.17 Thu Nov 20 08:45:36 CET 2008
154 - (libeio) added aio_sync_file_range (untested).
155 - add aio_busy to @IO::AIO::AIO_REQ.
156
1573.16 Wed Oct 22 18:28:01 CEST 2008
158 - use SvREFCNT_inc instead of SvREFCNT_inc_NN in a non-speed critical
159 part to improve portability to perl 5.8 (reported by szymon).
160
1613.15 Mon Oct 13 00:39:55 CEST 2008
162 - automatic removal of feeders was broken.
163 - (libeio) use a more robust method to detect whether a feeder
164 has added something to the group or not.
165
1663.1 Thu Oct 2 13:34:40 CEST 2008
167 - pre-deref the passed callback object, for increased speed
168 and decreased memory usage.
169 - call on_next_submit callback even for aio_group - impact unknown,
170 but seems more correct.
171 - $req->cb now returns the original callback.
172 - (libeio) pass EIO_GROUP/aio_group requests through the queue without
173 requiring a thread switch.
174 - (libeio) status code of aio_futime and aio_utime was always passed 0.
175 - do some other ยต-optimisations.
176
1773.07 Sat Aug 2 16:06:13 CEST 2008
178 - do not include LIBS in autoconf tests.
179
1803.06 Tue Jul 15 12:41:32 CEST 2008
181 - move preadwritelock definition before it's first reference,
182 to make it compile again on broken platforms (they still exist)
183 or badly cofngiured perls (redhat...), reported by Rob Bloodgood.
184
1853.05 Thu Jun 19 23:23:52 CEST 2008
186 - work around perl overriding readdir etc. with thread-unsafe
187 (sic!) versions.
188
1893.04 Wed Jun 18 01:35:38 CEST 2008
190 - (libeio) fix eio_mknod, which confused it's arguments.
191 - (libeio) do not use readdir_r, as Ulrich Drepper pointed out that this
192 is stupid.
193 - (libeio) fix eio__readahead prototype, patch by Jost Krieger.
194 - (libeio) fix a bug that could potentially cause IO::AIO
195 not to get initialised properly.

202 - document the new IO::AIO::poll_cb result value.
203
2043.02 Mon May 12 02:32:02 CEST 2008
205 - fix a memory leak on aio_readlink.
206 - bring back working fchmod.
207 - nop and busy now set result to 0.
208 - set errno to ENOMEM when allocation fails.
209
2103.01 Sun May 11 03:07:03 CEST 2008
211 - (libeio) make it compile on systems without readahead or readdir_r.
212 - (libeio) improve configure check for readahead availability.
213 - do not try to link against -lrt.
214 - use a separate configure script for IO::AIO (not the libeio one).
215
2163.0 Sun May 11 00:57:14 CEST 2008
217 - added bin/treescan to the distribution.
218 - switched to using libeio.
219 - LOTS OF INCOMPATIBLE CHANGES:
220 - remove signal functionality, it is not worth the effort.
221 - max_outstanding no longer returns the previous number of requests.
222 - poll_cb no longer returns number of requests.
223
2242.62 Sat Apr 26 13:59:33 CEST 2008
225 - port to solaris perls configured for old posix
226 (analysed by Jost Krieger).
227 - keep a reference to the perl filehandle object in aio_close,
228 so it doesn't get closed prematurely, leading to ugly races.
229
2302.61 Wed Apr 16 18:45:02 CEST 2008
9 - fix treescan output duplication and improve output ordering. 231 - fix treescan output duplication and improve output ordering.
10 also display files given on the commandline. 232 also display files given on the commandline.
233 - use a different algorithm for aio_close that is faster
234 and probably has even lower chances of blocking.
11 - do our own stack memory management for threads - linux 235 - do our own stack memory management for threads - linux
12 allocates outrageous amounts of VM (not so bad unless you 236 allocates outrageous amounts of VM (not so bad unless you
13 use mlockall...), which severely limits the number of threads 237 use mlockall...), which severely limits the number of threads
14 on 32-bit arches. 238 on 32-bit arches: stack size is the larger of PTHREAD_STACK_MIN
239 and 4096 * sizeof (long) (usually this is 16..64k).
15 240
