254.2 Sat Jan 25 01:13:14 CET 2014
26 - aio_group could corrupt memory because it didn't restore
27 the stack after req_submit.
28 - be more careful on (e.g. permission) errors in bin/treescan.
29 - work around changes in ExtUtils::MakeMaker.
30 - (libeio) implement aio_realpath for win32.
31 - (xthread) work around compile time bugs in ptw32.
32 - added IO::AIO::pipesize.
33 - (libecb) insignificant update.
34
354.19 Sun Jan 6 12:47:26 CET 2013
36 - avoid endless loop in fiemap with some XFS files.
37 - in aio_rename and aio_rmdir, specialcase the case of [$wd, "."]
38 and call rename/rmdir instead of renameat/unlinkat.
39
404.18 Thu Oct 11 07:01:26 CEST 2012
41 - fix unintended xthread_create by intentionalising it :)
42
434.17 Thu Oct 11 05:19:47 CEST 2012
44 - rename aio_fallocate to aio_allocate, to match documentation.
45 - add list of linux fsid values to aio_statvfs docs.
46 - work around a bug in btrfs' FIEMAP ioctl implementation.
47 - work around AIX bug: statvfs.f_fsid is a struct, not unsigned long
48 as per unix spec.
49
504.16 Tue Aug 14 05:39:03 CEST 2012
51 - aio_statvfs was wromgly marked for wd emulation, causing
52 it to malfunction for paths.
53 - fix a crash in aio_fiemap, when used on ranges without any
54 extents.
55 - work around linux kernel bug (at least in 3.2): kernel might
56 trash fiemap input arguments.
57 - work around linux kernel bug (at least in 3.2): kernel does not
58 set FIEMAP_EXTENT_LAST on last segment.
59 - work around linux kernel bug (at least in 3.2): kernel silently
60 truncates segment count if a file.
61 - make fh argument of IO::AIO::mmap optional, also add mmap/munmap
62 to quick overview.
63 - splice can corrupt data.
64 - (libeio) remove pread/pwrite emulation.
65 - do not grow mmaped scalars in aio_read.
66 - add FALLOC_FL_PUNCH_HOLE and document fallocate.
67 - provide pread/pwrite for win32, making it link again on native win32.
68
694.15 Tue Apr 10 06:59:00 CEST 2012
70 - always include linux/types.h for fiemap, for compatibility to
71 ancient systems (Paul Howarth).
72 - experimental support for IO::AIO::splice and ::tee (no aio_...).
73 - provide SEEK_HOLE and SEEK_DATA, if available.
74 - work around (again!) an immensely stupid bug in RHEL, defining
75 autoconf macros in linux system headers (analysed by Paul Howarth).
76
774.14 Sat Apr 7 02:45:18 CEST 2012
78 - fix stat structure usage on windows, which caused bogus stat results.
79 - (libeio) make readahead emulation behave more like actual readahead by never failing.
80 - new request aio_seek.
81 - new request aio_fiemap.
82 - autogenerate the #ifdef/#define 0 blocks for symbols we export.
83
844.12 Fri Dec 30 08:51:25 CET 2011
85 - realpath would return a random value if the name was too long,
86 instead of -1.
87 - port to c89.
88
894.11 Mon Oct 10 00:24:11 CEST 2011
90 - libeio didn't compile on !linux (Paul Howarth).
91
924.1 Sun Oct 9 10:24:11 CEST 2011
93 - IO::AIO did access uninitialised memory on unsuccessful stats.
94 - (libeio) added syncfs syscall wrapper.
95 - (libeio) set thread name on linux (ps -L/Hcx, top, gdb).
96 - (libeio) support multiple indepenent working directories.
97 - applied speling corrections by Nicholas Bamber.
98 - tune treescan #threads and #outstanding requests a bit.
99 - reduce the number of file descriptors in use at any one time
100 in treescan, to avoid running out of them (and using too much ram).
101 - take advantage of working directoriy abstractions
102 in aio_scandir and treescan.
103 - reduce compiled size by ~10% by not inlining some key functionality.
104 - added --progress switch to treescan.
105
1064.0 Mon Jul 18 05:01:10 CEST 2011
107 - INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
108 see FORK BEHAVIOUR in manpage for details.
109 - passes testsuite on win32 now and may actually work
110 (activestate 5.10.1 / MSVC6, YMMV).
111 - (libeio) fix a deadlock where a wakeup signal could be missed when
112 a timeout occured at the same time.
113 - (libeio) added realpath.
114 - (libeio) added fallocate.
115 - (libeio) disabling sendfile on darwin unfortunately broke the emulation.
116 - (libeio) do not acquire any locks when forking.
117 - (libeio) use fewer time() syscalls when waiting for new requests.
118
1193.93 Wed Jun 29 23:44:18 CEST 2011
120 - ECB.H WAS MISSING.
121
1223.92 Wed Jun 29 14:45:41 CEST 2011
123 - ecb.h was missing.
124
1253.91 Wed Jun 29 13:24:42 CEST 2011
126 - (libeio) work around a Linux (and likely FreeBSD and other
127 kernels) bug where sendfile would not transfer all the requested
128 bytes on large transfers, using a heuristic.
129 - buggy sendfile caused aio_move/copy to sometimes fail for big
130 files (fortunately it checks that the whole file has been
131 transferred...)
132 - use libecb for higher performance and higher portability.
133 - (libeio) disable sendfile on darwin, it's too broken.
134 - disable fork tests on !linux, as only linux supports mixing
135 pthread and fork in perl.
136 - document the fact that fork doesn't work anymore when using
137 this module, on anything !GNU/Linux.
138 - increase timeout in t/04_fork.t, as too many CPAN-tester setups
139 run on a 0.1MHz cpu. Or so.
140
1413.9 Fri May 27 02:43:47 CEST 2011
142 - (libeio) fix memory corruption in aio_readdirx for the flags
143 combination READDIR_STAT_ORDER | READDIR_DIRS_FIRST.
144 - add lots of newer POSIX and GNU/Linux-specific open
145 flags.
146
1473.8 Sun Mar 27 12:25:33 CEST 2011
148 - use nonstandard but maybe-working-on-bsd fork technique.
149 - support a max_idle value of 0.
150 - support setting of idle timeout value (IO::AIO::idle_timeout).
151
1523.72 Fri Feb 11 04:25:38 CET 2011
153 - use _POSIX_MEMLOCK_RANGE to detect mlock/munlock.
154 - aio_mknod always used a dev_t value of 0.
155 - new treescan option: --grep.
156 - add more S_IF macros, and major/minor/makedev "macros".
157
1583.71 Thu Dec 30 08:18:46 CET 2010
159 - the numerical result value passed to callbacks did not stringify
160 correctly, due to internal reuse and failure to reset the sv flags.
161 - actually test for posix_[mf]advise, as at least uClibc defines
162 _POSIX_ADVISORY_INFO without actually having any of the required
163 funcitonality. ugh.
164
1653.7 Mon Nov 1 23:00:34 CET 2010
166 - implement/add madvise, mmap, munmap, aio_mlockall, munlockall,
167 aio_mlock, munlock, msync and mtouch to @EXPORT_OK.
168 - document the sad state of affairs w.r.t. pthread on many bsds.
169 - do not enable mmap on systems without _POSIX_MAPPED_FILES
170 (openbsd 4.8).
171 - do not leak memory in IO::AIO::mmap when the scalar already
172 had string-data.
173 - add O_RDWR, O_APPEND and O_EXCL symbols and semi-document
174 them.
175 - cache the result IV, for a minor speedup in the common case.
176 - croak when an mmapped-scalar changes location, to detect
177 user-errors better.
178 - fix aio_readlink prototype.
179
1803.65 Wed Mar 31 02:45:05 CEST 2010
181 - actually use PATH_MAX instead of NAME_MAX for readlink, as to not
182 cut off long pathnames in aio_readlink (based on patch by
183 Rasmus Andersson).
184 - a double fork partially killed the event pipe (great testcase
185 by dormando). affects IO::AIO, BDB and Async::Interrupt.
186 - suck steve's dick and rename our symbols to avoid colliding
187 with nonstandard identifier spam on the broken os x pseudo-os.
188 affects IO::AIO and BDB.
189
1903.6 Mon Jan 11 00:43:39 CET 2010
191 - (libeio) more fixes for the freebsd/apple sendfile - broken by
192 manpage standards, but apparently correct accoridng to actual
193 kernel sources.
194 - add IO::AIO::mmap/munmap support.
195 - add IO::AIO::m(un)lockall support.
196 - clean up manpage.
197
1983.5 Thu Jan 7 21:25:04 CET 2010

200 - (libeio) also fix darwin sendfile that suffered from a similar bug.
201 - add aio_statvfs as interface to statvfs/fstatvfs.
202 - work around buggy symlink() on cygwin in the testsuite.
203 - wtf. freebsd-8.0 actually passes the testsuite! I knew
204 they could implement fork and semaphores one day! cheers!
205
2063.4 Sat Jan 2 15:13:04 CET 2010
207 - (libeio) max_poll_time was not properly converted to ticks.
208 - clarify cancel_subs description.
209 - IO::AIO::sendfile did not actually return the return value
210 from the sendfile call.
211 - implement aio_msync, aio_mtouch.
212 - (libeio) tentatively support darwin in sendfile.
213
2143.31 Thu Nov 12 02:14:29 CET 2009
10 - fix result status documentation of aio_copy, aio_move. 215 - fix result status documentation of aio_copy, aio_move.
