38 - new aio_slurp request.
39 - removed filesystem magic number table from aio_statvfs docs as
40 statvfs doesn't actually return this info at all (statfs does).
41 - add a bunch of (mostly linux-specific) constants for use in ioctls
42 (see aio_ioctl docs).
43 - treescan now has a proper manpage and useful --help output.
44 - new option --sync in treescan, to sync everything in a subtree.
45 - changed default for aio_msync flags to MSYNC_SYNC.
46 - document offset/length behaviour of mprotect/madvise.

57
584.34 Sun May 1 19:18:24 CEST 2016
59 - def0.h was not properly generated during previous release, causing
60 compile errors on various platforms.
61 - major/minor were accidentally switched (reported by Alexander Lishenyuk).
62 - removed duplicate definition of MAP_HUGETLB, that was found due to
63 a bug in Perl::Tidy (testcase by alaska332@gmail.com).
64 - added (untested!) aio_fcntl, aio_ioctl requests.
65 - (libeio) names set via prctl are truncated to 15 chars + nul, not 16,
66 as manpages-dev originally claimed.
67
684.33 Mon Jan 18 12:50:10 CET 2016
69 - add IO::AIO::pipe2 function.
70 - added support for FALLOC_FL_COLLAPSE_RANGE and FALLOC_FL_ZERO_RANGE
71 constants.
72 - added support for O_TMPFILE and O_PATH constants.

79
804.32 Wed Feb 11 20:32:11 CET 2015

86 - work around more 5.20 bugs. backwards compatibility my ass.
87
884.3 Fri Apr 11 06:22:38 CEST 2014
89 - perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
90 without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
91 in 5.18. What's so attractive about giving a shit about backwards
92 compatibility - I will never understand.
93
944.2 Sat Jan 25 01:13:14 CET 2014
95 - aio_group could corrupt memory because it didn't restore
96 the stack after req_submit.

108
1094.18 Thu Oct 11 07:01:26 CEST 2012

113 - rename aio_fallocate to aio_allocate, to match documentation.
114 - add list of linux fsid values to aio_statvfs docs.
115 - work around a bug in btrfs' FIEMAP ioctl implementation.
116 - work around AIX bug: statvfs.f_fsid is a struct, not unsigned long
117 as per unix spec.
118
1194.16 Tue Aug 14 05:39:03 CEST 2012
120 - aio_statvfs was wromgly marked for wd emulation, causing
121 it to malfunction for paths.
122 - fix a crash in aio_fiemap, when used on ranges without any
123 extents.
124 - work around linux kernel bug (at least in 3.2): kernel might
125 trash fiemap input arguments.
126 - work around linux kernel bug (at least in 3.2): kernel does not
127 set FIEMAP_EXTENT_LAST on last segment.
128 - work around linux kernel bug (at least in 3.2): kernel silently
129 truncates segment count if a file.

137
1384.15 Tue Apr 10 06:59:00 CEST 2012
139 - always include linux/types.h for fiemap, for compatibility to
140 ancient systems (Paul Howarth).
141 - experimental support for IO::AIO::splice and ::tee (no aio_...).
142 - provide SEEK_HOLE and SEEK_DATA, if available.
143 - work around (again!) an immensely stupid bug in RHEL, defining
144 autoconf macros in linux system headers (analysed by Paul Howarth).
145
1464.14 Sat Apr 7 02:45:18 CEST 2012
147 - fix stat structure usage on windows, which caused bogus stat results.
148 - (libeio) make readahead emulation behave more like actual readahead by never failing.
149 - new request aio_seek.
150 - new request aio_fiemap.
151 - autogenerate the #ifdef/#define 0 blocks for symbols we export.
152
1534.12 Fri Dec 30 08:51:25 CET 2011
154 - realpath would return a random value if the name was too long,
155 instead of -1.
156 - port to c89.
157
1584.11 Mon Oct 10 00:24:11 CEST 2011
159 - libeio didn't compile on !linux (Paul Howarth).
160
1614.1 Sun Oct 9 10:24:11 CEST 2011
162 - IO::AIO did access uninitialised memory on unsuccessful stats.
163 - (libeio) added syncfs syscall wrapper.
164 - (libeio) set thread name on linux (ps -L/Hcx, top, gdb).
165 - (libeio) support multiple indepenent working directories.
166 - applied speling corrections by Nicholas Bamber.
167 - tune treescan #threads and #outstanding requests a bit.
168 - reduce the number of file descriptors in use at any one time
169 in treescan, to avoid running out of them (and using too much ram).
170 - take advantage of working directoriy abstractions
171 in aio_scandir and treescan.
172 - reduce compiled size by ~10% by not inlining some key functionality.
173 - added --progress switch to treescan.
174
1754.0 Mon Jul 18 05:01:10 CEST 2011
176 - INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
177 see FORK BEHAVIOUR in manpage for details.
178 - passes testsuite on win32 now and may actually work
179 (activestate 5.10.1 / MSVC6, YMMV).
180 - (libeio) fix a deadlock where a wakeup signal could be missed when
181 a timeout occured at the same time.
182 - (libeio) added realpath.
183 - (libeio) added fallocate.
184 - (libeio) disabling sendfile on darwin unfortunately broke the emulation.
185 - (libeio) do not acquire any locks when forking.
186 - (libeio) use fewer time() syscalls when waiting for new requests.
187
1883.93 Wed Jun 29 23:44:18 CEST 2011
189 - ECB.H WAS MISSING.
190
1913.92 Wed Jun 29 14:45:41 CEST 2011
192 - ecb.h was missing.
193
1943.91 Wed Jun 29 13:24:42 CEST 2011
195 - (libeio) work around a Linux (and likely FreeBSD and other
196 kernels) bug where sendfile would not transfer all the requested
197 bytes on large transfers, using a heuristic.
198 - buggy sendfile caused aio_move/copy to sometimes fail for big
199 files (fortunately it checks that the whole file has been
200 transferred...)
201 - use libecb for higher performance and higher portability.
202 - (libeio) disable sendfile on darwin, it's too broken.
203 - disable fork tests on !linux, as only linux supports mixing
204 pthread and fork in perl.
205 - document the fact that fork doesn't work anymore when using
206 this module, on anything !GNU/Linux.
207 - increase timeout in t/04_fork.t, as too many CPAN-tester setups
208 run on a 0.1MHz cpu. Or so.
209
2103.9 Fri May 27 02:43:47 CEST 2011
211 - (libeio) fix memory corruption in aio_readdirx for the flags
212 combination READDIR_STAT_ORDER | READDIR_DIRS_FIRST.

217 - use nonstandard but maybe-working-on-bsd fork technique.
218 - support a max_idle value of 0.
219 - support setting of idle timeout value (IO::AIO::idle_timeout).
220
2213.72 Fri Feb 11 04:25:38 CET 2011
222 - use _POSIX_MEMLOCK_RANGE to detect mlock/munlock.
223 - aio_mknod always used a dev_t value of 0.
224 - new treescan option: --grep.
225 - add more S_IF macros, and major/minor/makedev "macros".
226
2273.71 Thu Dec 30 08:18:46 CET 2010
228 - the numerical result value passed to callbacks did not stringify
229 correctly, due to internal reuse and failure to reset the sv flags.
230 - actually test for posix_[mf]advise, as at least uClibc defines
231 _POSIX_ADVISORY_INFO without actually having any of the required
232 funcitonality. ugh.
233
2343.7 Mon Nov 1 23:00:34 CET 2010
235 - implement/add madvise, mmap, munmap, aio_mlockall, munlockall,
236 aio_mlock, munlock, msync and mtouch to @EXPORT_OK.
237 - document the sad state of affairs w.r.t. pthread on many bsds.
238 - do not enable mmap on systems without _POSIX_MAPPED_FILES
239 (openbsd 4.8).
240 - do not leak memory in IO::AIO::mmap when the scalar already
241 had string-data.
12 - add O_RDWR, O_APPEND and O_EXCL symbols and semi-documented 242 - add O_RDWR, O_APPEND and O_EXCL symbols and semi-document
13 them. 243 them.
244 - cache the result IV, for a minor speedup in the common case.
245 - croak when an mmapped-scalar changes location, to detect
246 user-errors better.
247 - fix aio_readlink prototype.
14 248
153.65 Wed Mar 31 02:45:05 CEST 2010 2493.65 Wed Mar 31 02:45:05 CEST 2010
16 - actually use PATH_MAX instead of NAME_MAX for readlink, as to not 250 - actually use PATH_MAX instead of NAME_MAX for readlink, as to not
17 cut off long pathnames in aio_readlink (based on patch by 251 cut off long pathnames in aio_readlink (based on patch by
18 Rasmus Andersson). 252 Rasmus Andersson).
