12 - fix stat structure usage on windows, which caused bogus stat results.
13 - (libeio) make readahead emulation behave more like actual readahead by never failing.
14
154.12 Fri Dec 30 08:51:25 CET 2011
16 - realpath would return a random value if the name was too long,
17 instead of -1.
18 - port to c89.
19
204.11 Mon Oct 10 00:24:11 CEST 2011
21 - libeio didn't compile on !linux (Paul Howarth).
22
234.1 Sun Oct 9 10:24:11 CEST 2011
24 - IO::AIO did access uninitialised memory on unsuccessful stats.
25 - (libeio) added syncfs syscall wrapper.
26 - (libeio) set thread name on linux (ps -L/Hcx, top, gdb).
27 - (libeio) support multiple indepenent working directories.
28 - applied speling corrections by Nicholas Bamber.
29 - tune treescan #threads and #outstanding requests a bit.
30 - reduce the number of file descriptors in use at any one time
31 in treescan, to avoid running out of them (and using too much ram).
32 - take advantage of working directoriy abstractions
33 in aio_scandir and treescan.
34 - reduce compiled size by ~10% by not inlining some key functionality.
35 - added --progress switch to treescan.
36
374.0 Mon Jul 18 05:01:10 CEST 2011
38 - INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
39 see FORK BEHAVIOUR in manpage for details.
40 - passes testsuite on win32 now and may actually work
41 (activestate 5.10.1 / MSVC6, YMMV).
42 - (libeio) fix a deadlock where a wakeup signal could be missed when
43 a timeout occured at the same time.
44 - (libeio) added realpath.
45 - (libeio) added fallocate.
46 - (libeio) disabling sendfile on darwin unfortunately broke the emulation.
47 - (libeio) do not acquire any locks when forking.
48 - (libeio) use fewer time() syscalls when waiting for new requests.
49
503.93 Wed Jun 29 23:44:18 CEST 2011
51 - ECB.H WAS MISSING.
52
533.92 Wed Jun 29 14:45:41 CEST 2011
54 - ecb.h was missing.
55
563.91 Wed Jun 29 13:24:42 CEST 2011
57 - (libeio) work around a Linux (and likely FreeBSD and other
58 kernels) bug where sendfile would not transfer all the requested
59 bytes on large transfers, using a heuristic.
60 - buggy sendfile caused aio_move/copy to sometimes fail for big
61 files (fortunately it checks that the whole file has been
62 transferred...)
63 - use libecb for higher performance and higher portability.
64 - (libeio) disable sendfile on darwin, it's too broken.
65 - disable fork tests on !linux, as only linux supports mixing
66 pthread and fork in perl.
67 - document the fact that fork doesn't work anymore when using
68 this module, on anything !GNU/Linux.
69 - increase timeout in t/04_fork.t, as too many CPAN-tester setups
70 run on a 0.1MHz cpu. Or so.
71
723.9 Fri May 27 02:43:47 CEST 2011
73 - (libeio) fix memory corruption in aio_readdirx for the flags
74 combination READDIR_STAT_ORDER | READDIR_DIRS_FIRST.
75 - add lots of newer POSIX and GNU/Linux-specific open
76 flags.
77
783.8 Sun Mar 27 12:25:33 CEST 2011
79 - use nonstandard but maybe-working-on-bsd fork technique.
80 - support a max_idle value of 0.
81 - support setting of idle timeout value (IO::AIO::idle_timeout).
82
833.72 Fri Feb 11 04:25:38 CET 2011
84 - use _POSIX_MEMLOCK_RANGE to detect mlock/munlock.
85 - aio_mknod always used a dev_t value of 0.
86 - new treescan option: --grep.
87 - add more S_IF macros, and major/minor/makedev "macros".
88
893.71 Thu Dec 30 08:18:46 CET 2010
90 - the numerical result value passed to callbacks did not stringify
91 correctly, due to internal reuse and failure to reset the sv flags.
92 - actually test for posix_[mf]advise, as at least uClibc defines
93 _POSIX_ADVISORY_INFO without actually having any of the required
94 funcitonality. ugh.
95
963.7 Mon Nov 1 23:00:34 CET 2010
97 - implement/add madvise, mmap, munmap, aio_mlockall, munlockall,
98 aio_mlock, munlock, msync and mtouch to @EXPORT_OK.
99 - document the sad state of affairs w.r.t. pthread on many bsds.
100 - do not enable mmap on systems without _POSIX_MAPPED_FILES
101 (openbsd 4.8).
102 - do not leak memory in IO::AIO::mmap when the scalar already
103 had string-data.
104 - add O_RDWR, O_APPEND and O_EXCL symbols and semi-document
105 them.
106 - cache the result IV, for a minor speedup in the common case.
107 - croak when an mmapped-scalar changes location, to detect
108 user-errors better.
109 - fix aio_readlink prototype.
110
1113.65 Wed Mar 31 02:45:05 CEST 2010
112 - actually use PATH_MAX instead of NAME_MAX for readlink, as to not
113 cut off long pathnames in aio_readlink (based on patch by
114 Rasmus Andersson).
115 - a double fork partially killed the event pipe (great testcase
116 by dormando). affects IO::AIO, BDB and Async::Interrupt.
117 - suck steve's dick and rename our symbols to avoid colliding
118 with nonstandard identifier spam on the broken os x pseudo-os.
119 affects IO::AIO and BDB.
120
1213.6 Mon Jan 11 00:43:39 CET 2010
122 - (libeio) more fixes for the freebsd/apple sendfile - broken by
123 manpage standards, but apparently correct accoridng to actual
124 kernel sources.
125 - add IO::AIO::mmap/munmap support.
126 - add IO::AIO::m(un)lockall support.
127 - clean up manpage.
128
1293.5 Thu Jan 7 21:25:04 CET 2010
130 - (liebio) fix freebsd sendfile (Vanilla Hsu).
131 - (libeio) also fix darwin sendfile that suffered from a similar bug.
132 - add aio_statvfs as interface to statvfs/fstatvfs.
133 - work around buggy symlink() on cygwin in the testsuite.
134 - wtf. freebsd-8.0 actually passes the testsuite! I knew
135 they could implement fork and semaphores one day! cheers!
136
1373.4 Sat Jan 2 15:13:04 CET 2010
138 - (libeio) max_poll_time was not properly converted to ticks.
139 - clarify cancel_subs description.
140 - IO::AIO::sendfile did not actually return the return value
141 from the sendfile call.
142 - implement aio_msync, aio_mtouch.
143 - (libeio) tentatively support darwin in sendfile.
144
1453.31 Thu Nov 12 02:14:29 CET 2009
146 - fix result status documentation of aio_copy, aio_move.
147 - speed up object creation considerably by avoiding
148 hash lookups.
149
1503.3 Wed Aug 5 13:52:58 CEST 2009
151 - use common::sense.
152 - use common schmorp.h header.
153 - allow integers (file descriptors) in addition to file handles.
154 - take advantage of linux' eventfd (but it seems slower on smp?).
155 - use poll not select on posix platforms.
156
1573.261 Wed Jul 1 10:11:51 CEST 2009
158 - more 0S X workarounds (patch by Tokuhiro Matsuno).
159
1603.26 Tue Jun 30 09:33:26 CEST 2009
161 - 0S X of course claims to be posix 2008 but lacks posix_fadvise.
162 try to work around this horribly broken OS in a somewhat hackish
163 way. might help other os's too.
164
1653.25 Sat Jun 27 05:18:26 CEST 2009
166 - added IO::AIO::fadvise and IO::AIO::sendfile.
167 - (libeio) replaced quicksort+insertion sort by a tuned radix
168 sort + insertion sort, resulting in comparable runtime (usually
169 faster) to the old version, but without any ill side effects on
170 degenerated (for quicksort) data.
171 - (libeio) correctly sort dirs by inodes if we have perfect type
172 knowledge and DIRS_FIRST is used.
173 - (libeio) internally the wrong DT_* constants were used, but no
174 known system has differing EIO_DT_*/DT_* values, so not an issue.
175 - removed a (harmless) assert that was left over on the code
176 but should not have been.
177 - use more correct types (change IO length from IV to VAL64,
178 which makes a difference on systems without 64 bit perls).
179
1803.23 Sat Jun 13 16:57:58 CEST 2009
181 - fix off-by-one bug in aio_readdir that was introduced in the
182 rushed 3.22 release.
183
1843.22 Sat Jun 13 15:32:40 CEST 2009
185 - speed up readdirx sort algorithm slightly.
186 - bin/treescan was missing from distro tarball.
187
1883.21 Fri Jun 12 18:45:53 CEST 2009
189 - new options --dirs and --files for treescan.
190 - install bin/treescan by default.
191 - (libeio) aio_readdir can now be cancelled while executing.
192 - fix a printf format string for 64 bit systems (could lead
193 to problems on big endian 64 bit systems).
194 - do not use qsort() but our own algorithm: glibc initialises
195 the whole locale and I/O subsystem inside qsort, causing
196 a stack overflow on 32 bit machines. The new sort uses much less
197 stack and is more than twice as fast in typical situations.

93.2 Sun Jun 7 20:30:05 CEST 2009 1993.2 Sun Jun 7 20:30:05 CEST 2009
10 - (libeio) pwrite emulation was even more flawed than intended and did 200 - (libeio) pwrite emulation was even more flawed than intended and did
11 not restore the file offset. 201 not restore the file offset.
