45
464.32 Wed Feb 11 20:32:11 CET 2015
47 - replace off_t by STRLEN where appropriate, should not result in
48 user-visible changes.

50
514.31 Tue Jun 3 03:29:27 CEST 2014
52 - work around more 5.20 bugs. backwards compatibility my ass.
53
544.3 Fri Apr 11 06:22:38 CEST 2014
55 - perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
56 without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
57 in 5.18. What's so attractive about giving a shit about backwards
58 compatibility - I will never understand.
59
604.2 Sat Jan 25 01:13:14 CET 2014
61 - aio_group could corrupt memory because it didn't restore
62 the stack after req_submit.

64 - work around changes in ExtUtils::MakeMaker.
65 - (libeio) implement aio_realpath for win32.
66 - (xthread) work around compile time bugs in ptw32.
67 - added IO::AIO::pipesize.
68 - (libecb) insignificant update.
69
704.19 Sun Jan 6 12:47:26 CET 2013
71 - avoid endless loop in fiemap with some XFS files.
72 - in aio_rename and aio_rmdir, specialcase the case of [$wd, "."]
73 and call rename/rmdir instead of renameat/unlinkat.
74
754.18 Thu Oct 11 07:01:26 CEST 2012
76 - fix unintended xthread_create by intentionalising it :)
77
784.17 Thu Oct 11 05:19:47 CEST 2012
79 - rename aio_fallocate to aio_allocate, to match documentation.
80 - add list of linux fsid values to aio_statvfs docs.
81 - work around a bug in btrfs' FIEMAP ioctl implementation.
82 - work around AIX bug: statvfs.f_fsid is a struct, not unsigned long
83 as per unix spec.
84
854.16 Tue Aug 14 05:39:03 CEST 2012
86 - aio_statvfs was wromgly marked for wd emulation, causing
87 it to malfunction for paths.
88 - fix a crash in aio_fiemap, when used on ranges without any
89 extents.
90 - work around linux kernel bug (at least in 3.2): kernel might
91 trash fiemap input arguments.
92 - work around linux kernel bug (at least in 3.2): kernel does not
93 set FIEMAP_EXTENT_LAST on last segment.
94 - work around linux kernel bug (at least in 3.2): kernel silently
95 truncates segment count if a file.
96 - make fh argument of IO::AIO::mmap optional, also add mmap/munmap
97 to quick overview.
98 - splice can corrupt data.
99 - (libeio) remove pread/pwrite emulation.
100 - do not grow mmaped scalars in aio_read.
101 - add FALLOC_FL_PUNCH_HOLE and document fallocate.

103
1044.15 Tue Apr 10 06:59:00 CEST 2012
105 - always include linux/types.h for fiemap, for compatibility to
106 ancient systems (Paul Howarth).
107 - experimental support for IO::AIO::splice and ::tee (no aio_...).
108 - provide SEEK_HOLE and SEEK_DATA, if available.
109 - work around (again!) an immensely stupid bug in RHEL, defining
110 autoconf macros in linux system headers (analysed by Paul Howarth).
111
1124.14 Sat Apr 7 02:45:18 CEST 2012
113 - fix stat structure usage on windows, which caused bogus stat results.
114 - (libeio) make readahead emulation behave more like actual readahead by never failing.
115 - new request aio_seek.
116 - new request aio_fiemap.
117 - autogenerate the #ifdef/#define 0 blocks for symbols we export.
118
1194.12 Fri Dec 30 08:51:25 CET 2011
120 - realpath would return a random value if the name was too long,
121 instead of -1.
122 - port to c89.
123
1244.11 Mon Oct 10 00:24:11 CEST 2011
125 - libeio didn't compile on !linux (Paul Howarth).
126
1274.1 Sun Oct 9 10:24:11 CEST 2011
128 - IO::AIO did access uninitialised memory on unsuccessful stats.
129 - (libeio) added syncfs syscall wrapper.
130 - (libeio) set thread name on linux (ps -L/Hcx, top, gdb).
131 - (libeio) support multiple indepenent working directories.
132 - applied speling corrections by Nicholas Bamber.
133 - tune treescan #threads and #outstanding requests a bit.
134 - reduce the number of file descriptors in use at any one time
135 in treescan, to avoid running out of them (and using too much ram).
136 - take advantage of working directoriy abstractions
137 in aio_scandir and treescan.
138 - reduce compiled size by ~10% by not inlining some key functionality.
139 - added --progress switch to treescan.
140
1414.0 Mon Jul 18 05:01:10 CEST 2011
142 - INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
143 see FORK BEHAVIOUR in manpage for details.
144 - passes testsuite on win32 now and may actually work
145 (activestate 5.10.1 / MSVC6, YMMV).
146 - (libeio) fix a deadlock where a wakeup signal could be missed when
147 a timeout occured at the same time.
148 - (libeio) added realpath.
149 - (libeio) added fallocate.
150 - (libeio) disabling sendfile on darwin unfortunately broke the emulation.
151 - (libeio) do not acquire any locks when forking.
152 - (libeio) use fewer time() syscalls when waiting for new requests.
153
1543.93 Wed Jun 29 23:44:18 CEST 2011
155 - ECB.H WAS MISSING.
156
1573.92 Wed Jun 29 14:45:41 CEST 2011
158 - ecb.h was missing.
159
1603.91 Wed Jun 29 13:24:42 CEST 2011
161 - (libeio) work around a Linux (and likely FreeBSD and other
162 kernels) bug where sendfile would not transfer all the requested
163 bytes on large transfers, using a heuristic.
164 - buggy sendfile caused aio_move/copy to sometimes fail for big
165 files (fortunately it checks that the whole file has been
166 transferred...)
167 - use libecb for higher performance and higher portability.
168 - (libeio) disable sendfile on darwin, it's too broken.
169 - disable fork tests on !linux, as only linux supports mixing
170 pthread and fork in perl.
171 - document the fact that fork doesn't work anymore when using
172 this module, on anything !GNU/Linux.
173 - increase timeout in t/04_fork.t, as too many CPAN-tester setups
174 run on a 0.1MHz cpu. Or so.
175
1763.9 Fri May 27 02:43:47 CEST 2011
177 - (libeio) fix memory corruption in aio_readdirx for the flags
178 combination READDIR_STAT_ORDER | READDIR_DIRS_FIRST.
179 - add lots of newer POSIX and GNU/Linux-specific open
180 flags.
181
1823.8 Sun Mar 27 12:25:33 CEST 2011
183 - use nonstandard but maybe-working-on-bsd fork technique.
184 - support a max_idle value of 0.
185 - support setting of idle timeout value (IO::AIO::idle_timeout).
186
1873.72 Fri Feb 11 04:25:38 CET 2011
188 - use _POSIX_MEMLOCK_RANGE to detect mlock/munlock.
189 - aio_mknod always used a dev_t value of 0.
190 - new treescan option: --grep.
191 - add more S_IF macros, and major/minor/makedev "macros".
192
1933.71 Thu Dec 30 08:18:46 CET 2010
194 - the numerical result value passed to callbacks did not stringify
195 correctly, due to internal reuse and failure to reset the sv flags.
196 - actually test for posix_[mf]advise, as at least uClibc defines
197 _POSIX_ADVISORY_INFO without actually having any of the required
198 funcitonality. ugh.
199
2003.7 Mon Nov 1 23:00:34 CET 2010
201 - implement/add madvise, mmap, munmap, aio_mlockall, munlockall,
202 aio_mlock, munlock, msync and mtouch to @EXPORT_OK.
203 - document the sad state of affairs w.r.t. pthread on many bsds.
204 - do not enable mmap on systems without _POSIX_MAPPED_FILES
205 (openbsd 4.8).
206 - do not leak memory in IO::AIO::mmap when the scalar already
207 had string-data.
208 - add O_RDWR, O_APPEND and O_EXCL symbols and semi-document
209 them.
210 - cache the result IV, for a minor speedup in the common case.
211 - croak when an mmapped-scalar changes location, to detect
212 user-errors better.
213 - fix aio_readlink prototype.
214
2153.65 Wed Mar 31 02:45:05 CEST 2010
216 - actually use PATH_MAX instead of NAME_MAX for readlink, as to not
217 cut off long pathnames in aio_readlink (based on patch by
218 Rasmus Andersson).
219 - a double fork partially killed the event pipe (great testcase
220 by dormando). affects IO::AIO, BDB and Async::Interrupt.
221 - suck steve's dick and rename our symbols to avoid colliding
222 with nonstandard identifier spam on the broken os x pseudo-os.
223 affects IO::AIO and BDB.
224
2253.6 Mon Jan 11 00:43:39 CET 2010
11 - (libeio) more fixes for the freebsd/apple sendfile - broken by 226 - (libeio) more fixes for the freebsd/apple sendfile - broken by
12 manpage standards, but apparently correct accoridng to actual 227 manpage standards, but apparently correct accoridng to actual
13 kernel sources. 228 kernel sources.
229 - add IO::AIO::mmap/munmap support.
14 - add IO::AIO::m(un)lockall support. 230 - add IO::AIO::m(un)lockall support.

17 - (liebio) fix freebsd sendfile (Vanilla Hsu). 234 - (liebio) fix freebsd sendfile (Vanilla Hsu).
18 - (libeio) also fix darwin sendfile that suffered from a similar bug. 235 - (libeio) also fix darwin sendfile that suffered from a similar bug.
19 - add aio_statvfs as interface to statvfs/fstatvfs. 236 - add aio_statvfs as interface to statvfs/fstatvfs.
