12 41
42 - add IO::AIO::MCL_ONFAULT for mlockall.
43 - neither sys/mkdev.h nor sys/sysmacros.h were included, even when they
44 were detected by autoconf.
45
464.6 Sat Aug 25 21:58:36 CEST 2018
47 - add st_btime, st_btimesec, st_btimensec and st_gen accessors,
48 mostly for bsds which expose birthtime and st_gen members (netbsd, freebsd
49 but only st_gen on openbsd because they compiled their perl without support
50 for birthtimes).
51 - fix madvise and munlock to properly support negative offsets.
52 - allocate fd for the aio_close at boot time, to guarantee it working
53 later, rather than calling abort when it fails. also avoids
54 close-on-exec race issues after module load.
55 - #undef utime on win32, maybe this helps some reports of utime hangs.
56 - minor doc improvements.
57 - minor configure cleanups.
58 - use $Config{perllibs} instead of libs for configure. might help people
59 who didn'T install all perl dependencies (might break things as well).
60
614.54 Tue Aug 14 13:54:48 CEST 2018
62 - include sys/mkdev.h or sys/sysmacros.h if available.
63 - further tweaks to configure invocation for systems requiring --rpath.
64 - no longer rely on custom paths on win32 platforms.
65 - try to work around buggy PAGESIZE macro on solaris.
66
674.53 Tue Aug 14 11:27:50 CEST 2018
68 - add $Config{libs} to LIBS for configure, to work around systems
69 with broken library dependencies (... openbsd).
70
714.52 Sun Aug 12 08:09:45 CEST 2018
72 - config.h.in was missing in distribution.
73
744.51 Sun Aug 12 07:24:14 CEST 2018
75 - complete rework of the autoconf framework: IO::AIO now uses its own
76 config.h, separate from libeio, and tries to test the actual perl
77 environment, not the standard system environment.
78 - provide nanosecond-accracy stat time accessors for both perl and IO::AIO
79 stat functions.
80 - removed non-portable C++ syntax from eio.c.
81 - try to fix readdir tests on cygwin spuriously failing.
82
834.5 Wed Aug 1 00:23:55 CEST 2018
84 - aio_mtouch touch all pages as requested, not just the first page in most cases.
85 - new function: IO::AIO::mremap, linux-specific mremap, with constants MREMAP_MAYMOVE
86 and MREMAP_FIXED.
87 - add O_ACCMODE.
88 - add (undocumented) MSG_CMSG_CLOEXEC and SOCK_CLOEXEC constants.
89
904.4 Tue Feb 20 07:54:12 CET 2018

92 - add (experimental) IO::AIO::eventfd and timerfd* function.
93 - add (experimental) IO::AIO::get_fdlimit and IO::AIO::min_fdlimit.
94 - point out that aio_copy overwrites existing files.
95 - removed filesystem magic number table from aio_statvfs docs as
96 statvfs doesn't actually return this info at all (statfs does).
97 - add a bunch of (mostly linux-specific) constants for use in ioctls
98 (see aio_ioctl docs).
99 - treescan now has a proper manpage and useful --help output.
100 - new option --sync in treescan, to sync everything in a subtree.
101 - changed default for aio_msync flags to MSYNC_SYNC.
102 - document offset/length behaviour of mprotect/madvise.
103 - support linux's renameat2 (via aio_rename2).
104 - add aio_rename2, an aio_rename with flags.
105 - add F_DUPPFD_CLOEXEC, F_OFD_[SG]ETLKW? constants.
106 - add FALLOC_FL_INSERT_RANGE, FALLOC_FL_UNSHARE_RANGE.

108 - (libeio) internal close() calls no longer disturb errno.
109 - add IO:AIO::FALLOC_FL_UNSHARE.

111 and better eventfd detection.
112
1134.34 Sun May 1 19:18:24 CEST 2016
114 - def0.h was not properly generated during previous release, causing
115 compile errors on various platforms.
116 - major/minor were accidentally switched (reported by Alexander Lishenyuk).
117 - removed duplicate definition of MAP_HUGETLB, that was found due to
118 a bug in Perl::Tidy (testcase by alaska332@gmail.com).
119 - added (untested!) aio_fcntl, aio_ioctl requests.
120 - (libeio) names set via prctl are truncated to 15 chars + nul, not 16,
121 as manpages-dev originally claimed.
122
1234.33 Mon Jan 18 12:50:10 CET 2016
124 - add IO::AIO::pipe2 function.
125 - added support for FALLOC_FL_COLLAPSE_RANGE and FALLOC_FL_ZERO_RANGE
126 constants.
127 - added support for O_TMPFILE and O_PATH constants.
128 - added support for MAP_FIXED, MAP_GROWSDOWN,MAP_32BIT, MAP_HUGETLB, MAP_STACK

134
1354.32 Wed Feb 11 20:32:11 CET 2015
136 - replace off_t by STRLEN where appropriate, should not result in
137 user-visible changes.

139
1404.31 Tue Jun 3 03:29:27 CEST 2014
141 - work around more 5.20 bugs. backwards compatibility my ass.
142
1434.3 Fri Apr 11 06:22:38 CEST 2014
144 - perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
145 without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
146 in 5.18. What's so attractive about giving a shit about backwards
147 compatibility - I will never understand.
148
1494.2 Sat Jan 25 01:13:14 CET 2014
150 - aio_group could corrupt memory because it didn't restore
151 the stack after req_submit.
152 - be more careful on (e.g. permission) errors in bin/treescan.
153 - work around changes in ExtUtils::MakeMaker.
154 - (libeio) implement aio_realpath for win32.

160 - avoid endless loop in fiemap with some XFS files.
161 - in aio_rename and aio_rmdir, specialcase the case of [$wd, "."]
162 and call rename/rmdir instead of renameat/unlinkat.
163
1644.18 Thu Oct 11 07:01:26 CEST 2012
165 - fix unintended xthread_create by intentionalising it :)
166
1674.17 Thu Oct 11 05:19:47 CEST 2012
168 - rename aio_fallocate to aio_allocate, to match documentation.
169 - add list of linux fsid values to aio_statvfs docs.
170 - work around a bug in btrfs' FIEMAP ioctl implementation.

172 as per unix spec.
173
1744.16 Tue Aug 14 05:39:03 CEST 2012
175 - aio_statvfs was wromgly marked for wd emulation, causing
176 it to malfunction for paths.
177 - fix a crash in aio_fiemap, when used on ranges without any
178 extents.
179 - work around linux kernel bug (at least in 3.2): kernel might
180 trash fiemap input arguments.
181 - work around linux kernel bug (at least in 3.2): kernel does not
182 set FIEMAP_EXTENT_LAST on last segment.
183 - work around linux kernel bug (at least in 3.2): kernel silently
184 truncates segment count if a file.
185 - make fh argument of IO::AIO::mmap optional, also add mmap/munmap
186 to quick overview.

192
1934.15 Tue Apr 10 06:59:00 CEST 2012
194 - always include linux/types.h for fiemap, for compatibility to
195 ancient systems (Paul Howarth).
196 - experimental support for IO::AIO::splice and ::tee (no aio_...).
197 - provide SEEK_HOLE and SEEK_DATA, if available.
198 - work around (again!) an immensely stupid bug in RHEL, defining
199 autoconf macros in linux system headers (analysed by Paul Howarth).
200
2014.14 Sat Apr 7 02:45:18 CEST 2012
202 - fix stat structure usage on windows, which caused bogus stat results.
203 - (libeio) make readahead emulation behave more like actual readahead by never failing.

205 - new request aio_fiemap.
206 - autogenerate the #ifdef/#define 0 blocks for symbols we export.
207
2084.12 Fri Dec 30 08:51:25 CET 2011
209 - realpath would return a random value if the name was too long,
210 instead of -1.
211 - port to c89.
212
2134.11 Mon Oct 10 00:24:11 CEST 2011

215
2164.1 Sun Oct 9 10:24:11 CEST 2011

220 - (libeio) support multiple indepenent working directories.
221 - applied speling corrections by Nicholas Bamber.
222 - tune treescan #threads and #outstanding requests a bit.
223 - reduce the number of file descriptors in use at any one time
224 in treescan, to avoid running out of them (and using too much ram).
225 - take advantage of working directoriy abstractions
226 in aio_scandir and treescan.
227 - reduce compiled size by ~10% by not inlining some key functionality.
228 - added --progress switch to treescan.
229
2304.0 Mon Jul 18 05:01:10 CEST 2011
231 - INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
232 see FORK BEHAVIOUR in manpage for details.
233 - passes testsuite on win32 now and may actually work
234 (activestate 5.10.1 / MSVC6, YMMV).
235 - (libeio) fix a deadlock where a wakeup signal could be missed when
236 a timeout occured at the same time.
237 - (libeio) added realpath.
238 - (libeio) added fallocate.
239 - (libeio) disabling sendfile on darwin unfortunately broke the emulation.

242
2433.93 Wed Jun 29 23:44:18 CEST 2011
244 - ECB.H WAS MISSING.
245

247 - ecb.h was missing.
248
2493.91 Wed Jun 29 13:24:42 CEST 2011
250 - (libeio) work around a Linux (and likely FreeBSD and other
251 kernels) bug where sendfile would not transfer all the requested
252 bytes on large transfers, using a heuristic.
253 - buggy sendfile caused aio_move/copy to sometimes fail for big
254 files (fortunately it checks that the whole file has been
255 transferred...)
256 - use libecb for higher performance and higher portability.
257 - (libeio) disable sendfile on darwin, it's too broken.
258 - disable fork tests on !linux, as only linux supports mixing
259 pthread and fork in perl.
260 - document the fact that fork doesn't work anymore when using
261 this module, on anything !GNU/Linux.
262 - increase timeout in t/04_fork.t, as too many CPAN-tester setups
263 run on a 0.1MHz cpu. Or so.
264
2653.9 Fri May 27 02:43:47 CEST 2011
266 - (libeio) fix memory corruption in aio_readdirx for the flags

273 - support a max_idle value of 0.
274 - support setting of idle timeout value (IO::AIO::idle_timeout).
275

13 - use _POSIX_MEMLOCK_RANGE to detetc mlock/munlock. 277 - use _POSIX_MEMLOCK_RANGE to detect mlock/munlock.
278 - aio_mknod always used a dev_t value of 0.
14 - new treescan option: --grep. 279 - new treescan option: --grep.
280 - add more S_IF macros, and major/minor/makedev "macros".
15 281
163.71 Thu Dec 30 08:18:46 CET 2010 2823.71 Thu Dec 30 08:18:46 CET 2010
17 - the numerical result value passed to callbacks did not stringify 283 - the numerical result value passed to callbacks did not stringify
18 correctly, due to internal reuse and failure to reset the sv flags. 284 correctly, due to internal reuse and failure to reset the sv flags.
19 - actually test for posix_[mf]advise, as at least uClibc defines 285 - actually test for posix_[mf]advise, as at least uClibc defines
