45
464.53 Tue Aug 14 11:27:50 CEST 2018
47 - add $Config{libs} to LIBS for configure, to work around systems
48 with broken library dependencies (... openbsd).
49
504.52 Sun Aug 12 08:09:45 CEST 2018
51 - config.h.in was missing in distribution.
52
534.51 Sun Aug 12 07:24:14 CEST 2018
54 - complete rework of the autoconf framework: IO::AIO now uses its own
55 config.h, separate from libeio, and tries to test the actual perl
56 environment, not the standard system environment.
57 - provide nanosecond-accracy stat time accessors for both perl and IO::AIO
58 stat functions.
59 - removed non-portable C++ syntax from eio.c.

72 - add (experimental) IO::AIO::get_fdlimit and IO::AIO::min_fdlimit.
73 - point out that aio_copy overwrites existing files.
74 - removed filesystem magic number table from aio_statvfs docs as
75 statvfs doesn't actually return this info at all (statfs does).
76 - add a bunch of (mostly linux-specific) constants for use in ioctls
77 (see aio_ioctl docs).
78 - treescan now has a proper manpage and useful --help output.

90 and better eventfd detection.
91
924.34 Sun May 1 19:18:24 CEST 2016
93 - def0.h was not properly generated during previous release, causing
94 compile errors on various platforms.
95 - major/minor were accidentally switched (reported by Alexander Lishenyuk).
96 - removed duplicate definition of MAP_HUGETLB, that was found due to
97 a bug in Perl::Tidy (testcase by alaska332@gmail.com).
98 - added (untested!) aio_fcntl, aio_ioctl requests.
99 - (libeio) names set via prctl are truncated to 15 chars + nul, not 16,
100 as manpages-dev originally claimed.
101
1024.33 Mon Jan 18 12:50:10 CET 2016
103 - add IO::AIO::pipe2 function.
104 - added support for FALLOC_FL_COLLAPSE_RANGE and FALLOC_FL_ZERO_RANGE

120 - work around more 5.20 bugs. backwards compatibility my ass.
121
1224.3 Fri Apr 11 06:22:38 CEST 2014
123 - perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
124 without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
125 in 5.18. What's so attractive about giving a shit about backwards
126 compatibility - I will never understand.
127
1284.2 Sat Jan 25 01:13:14 CET 2014
129 - aio_group could corrupt memory because it didn't restore
130 the stack after req_submit.

141 and call rename/rmdir instead of renameat/unlinkat.
142
1434.18 Thu Oct 11 07:01:26 CEST 2012
144 - fix unintended xthread_create by intentionalising it :)
145
1464.17 Thu Oct 11 05:19:47 CEST 2012
147 - rename aio_fallocate to aio_allocate, to match documentation.
148 - add list of linux fsid values to aio_statvfs docs.
149 - work around a bug in btrfs' FIEMAP ioctl implementation.
150 - work around AIX bug: statvfs.f_fsid is a struct, not unsigned long
151 as per unix spec.
152
1534.16 Tue Aug 14 05:39:03 CEST 2012
154 - aio_statvfs was wromgly marked for wd emulation, causing
155 it to malfunction for paths.
156 - fix a crash in aio_fiemap, when used on ranges without any
157 extents.
158 - work around linux kernel bug (at least in 3.2): kernel might
159 trash fiemap input arguments.
160 - work around linux kernel bug (at least in 3.2): kernel does not
161 set FIEMAP_EXTENT_LAST on last segment.
162 - work around linux kernel bug (at least in 3.2): kernel silently
163 truncates segment count if a file.
164 - make fh argument of IO::AIO::mmap optional, also add mmap/munmap
165 to quick overview.
166 - splice can corrupt data.

171
1724.15 Tue Apr 10 06:59:00 CEST 2012
173 - always include linux/types.h for fiemap, for compatibility to
174 ancient systems (Paul Howarth).
175 - experimental support for IO::AIO::splice and ::tee (no aio_...).
176 - provide SEEK_HOLE and SEEK_DATA, if available.
177 - work around (again!) an immensely stupid bug in RHEL, defining
178 autoconf macros in linux system headers (analysed by Paul Howarth).
179
1804.14 Sat Apr 7 02:45:18 CEST 2012
181 - fix stat structure usage on windows, which caused bogus stat results.
182 - (libeio) make readahead emulation behave more like actual readahead by never failing.

184 - new request aio_fiemap.
185 - autogenerate the #ifdef/#define 0 blocks for symbols we export.
186
1874.12 Fri Dec 30 08:51:25 CET 2011
188 - realpath would return a random value if the name was too long,
189 instead of -1.

191
1924.11 Mon Oct 10 00:24:11 CEST 2011

194
1954.1 Sun Oct 9 10:24:11 CEST 2011

200 - applied speling corrections by Nicholas Bamber.
201 - tune treescan #threads and #outstanding requests a bit.
202 - reduce the number of file descriptors in use at any one time
203 in treescan, to avoid running out of them (and using too much ram).
204 - take advantage of working directoriy abstractions
205 in aio_scandir and treescan.
206 - reduce compiled size by ~10% by not inlining some key functionality.
207 - added --progress switch to treescan.
208
2094.0 Mon Jul 18 05:01:10 CEST 2011
210 - INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
211 see FORK BEHAVIOUR in manpage for details.
212 - passes testsuite on win32 now and may actually work
213 (activestate 5.10.1 / MSVC6, YMMV).
214 - (libeio) fix a deadlock where a wakeup signal could be missed when
215 a timeout occured at the same time.

226 - ecb.h was missing.
227
2283.91 Wed Jun 29 13:24:42 CEST 2011
229 - (libeio) work around a Linux (and likely FreeBSD and other
230 kernels) bug where sendfile would not transfer all the requested
231 bytes on large transfers, using a heuristic.
232 - buggy sendfile caused aio_move/copy to sometimes fail for big
233 files (fortunately it checks that the whole file has been
234 transferred...)
235 - use libecb for higher performance and higher portability.
236 - (libeio) disable sendfile on darwin, it's too broken.
237 - disable fork tests on !linux, as only linux supports mixing
238 pthread and fork in perl.
239 - document the fact that fork doesn't work anymore when using
240 this module, on anything !GNU/Linux.
241 - increase timeout in t/04_fork.t, as too many CPAN-tester setups
242 run on a 0.1MHz cpu. Or so.

13 - use _POSIX_MEMLOCK_RANGE to detetc mlock/munlock. 256 - use _POSIX_MEMLOCK_RANGE to detect mlock/munlock.
257 - aio_mknod always used a dev_t value of 0.
14 - new treescan option: --grep. 258 - new treescan option: --grep.
259 - add more S_IF macros, and major/minor/makedev "macros".
15 260
163.71 Thu Dec 30 08:18:46 CET 2010 2613.71 Thu Dec 30 08:18:46 CET 2010
17 - the numerical result value passed to callbacks did not stringify 262 - the numerical result value passed to callbacks did not stringify
18 correctly, due to internal reuse and failure to reset the sv flags. 263 correctly, due to internal reuse and failure to reset the sv flags.
19 - actually test for posix_[mf]advise, as at least uClibc defines 264 - actually test for posix_[mf]advise, as at least uClibc defines
