40 - include sys/mkdev.h or sys/sysmacros.h if available.
41
424.53 Tue Aug 14 11:27:50 CEST 2018
43 - add $Config{libs} to LIBS for configure, to work around systems
44 with broken library dependencies (... openbsd).
45
464.52 Sun Aug 12 08:09:45 CEST 2018
47 - config.h.in was missing in distribution.
48
494.51 Sun Aug 12 07:24:14 CEST 2018
50 - complete rework of the autoconf framework: IO::AIO now uses its own
51 config.h, separate from libeio, and tries to test the actual perl
52 environment, not the standard system environment.
53 - provide nanosecond-accracy stat time accessors for both perl and IO::AIO
54 stat functions.
55 - removed non-portable C++ syntax from eio.c.
56 - try to fix readdir tests on cygwin spuriously failing.
57
584.5 Wed Aug 1 00:23:55 CEST 2018
59 - aio_mtouch touch all pages as requested, not just the first page in most cases.
60 - new function: IO::AIO::mremap, linux-specific mremap, with constants MREMAP_MAYMOVE
61 and MREMAP_FIXED.
62 - add O_ACCMODE.
63 - add (undocumented) MSG_CMSG_CLOEXEC and SOCK_CLOEXEC constants.
64
654.4 Tue Feb 20 07:54:12 CET 2018
66 - new aio_slurp request.
67 - add (experimental) IO::AIO::eventfd and timerfd* function.
68 - add (experimental) IO::AIO::get_fdlimit and IO::AIO::min_fdlimit.
69 - point out that aio_copy overwrites existing files.
70 - removed filesystem magic number table from aio_statvfs docs as
71 statvfs doesn't actually return this info at all (statfs does).
72 - add a bunch of (mostly linux-specific) constants for use in ioctls
73 (see aio_ioctl docs).
74 - treescan now has a proper manpage and useful --help output.
75 - new option --sync in treescan, to sync everything in a subtree.
76 - changed default for aio_msync flags to MSYNC_SYNC.
77 - document offset/length behaviour of mprotect/madvise.
78 - support linux's renameat2 (via aio_rename2).
79 - add aio_rename2, an aio_rename with flags.
80 - add F_DUPPFD_CLOEXEC, F_OFD_[SG]ETLKW? constants.
81 - add FALLOC_FL_INSERT_RANGE, FALLOC_FL_UNSHARE_RANGE.
82 - (libeio) use posix_close if available.
83 - (libeio) internal close() calls no longer disturb errno.
84 - add IO:AIO::FALLOC_FL_UNSHARE.
85 - update schmorp.h for removal of USE_SOCKETS_AS_HANDLES
86 and better eventfd detection.
87
884.34 Sun May 1 19:18:24 CEST 2016
89 - def0.h was not properly generated during previous release, causing
90 compile errors on various platforms.
91 - major/minor were accidentally switched (reported by Alexander Lishenyuk).
92 - removed duplicate definition of MAP_HUGETLB, that was found due to
93 a bug in Perl::Tidy (testcase by alaska332@gmail.com).
94 - added (untested!) aio_fcntl, aio_ioctl requests.
95 - (libeio) names set via prctl are truncated to 15 chars + nul, not 16,
96 as manpages-dev originally claimed.
97
984.33 Mon Jan 18 12:50:10 CET 2016
99 - add IO::AIO::pipe2 function.
100 - added support for FALLOC_FL_COLLAPSE_RANGE and FALLOC_FL_ZERO_RANGE
101 constants.
102 - added support for O_TMPFILE and O_PATH constants.
103 - added support for MAP_FIXED, MAP_GROWSDOWN,MAP_32BIT, MAP_HUGETLB, MAP_STACK
104 consdtants, whether they can be sensibly used or not.
105 - use NO_INIT where applicable.
106 - update libecb.
107 - added stability canary support.
108 - updated linux super magic table to 4.3.3.
109
1104.32 Wed Feb 11 20:32:11 CET 2015
111 - replace off_t by STRLEN where appropriate, should not result in
112 user-visible changes.
113 - update ecb.h for C11 compatibility.
114
1154.31 Tue Jun 3 03:29:27 CEST 2014
116 - work around more 5.20 bugs. backwards compatibility my ass.
117
1184.3 Fri Apr 11 06:22:38 CEST 2014
119 - perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
120 without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
121 in 5.18. What's so attractive about giving a shit about backwards
122 compatibility - I will never understand.
123
1244.2 Sat Jan 25 01:13:14 CET 2014
125 - aio_group could corrupt memory because it didn't restore
126 the stack after req_submit.
127 - be more careful on (e.g. permission) errors in bin/treescan.
128 - work around changes in ExtUtils::MakeMaker.
129 - (libeio) implement aio_realpath for win32.
130 - (xthread) work around compile time bugs in ptw32.
131 - added IO::AIO::pipesize.

135 - avoid endless loop in fiemap with some XFS files.
136 - in aio_rename and aio_rmdir, specialcase the case of [$wd, "."]
137 and call rename/rmdir instead of renameat/unlinkat.
138
1394.18 Thu Oct 11 07:01:26 CEST 2012
140 - fix unintended xthread_create by intentionalising it :)
141
1424.17 Thu Oct 11 05:19:47 CEST 2012
143 - rename aio_fallocate to aio_allocate, to match documentation.
144 - add list of linux fsid values to aio_statvfs docs.
145 - work around a bug in btrfs' FIEMAP ioctl implementation.
146 - work around AIX bug: statvfs.f_fsid is a struct, not unsigned long
147 as per unix spec.
148
1494.16 Tue Aug 14 05:39:03 CEST 2012
150 - aio_statvfs was wromgly marked for wd emulation, causing
151 it to malfunction for paths.
152 - fix a crash in aio_fiemap, when used on ranges without any
153 extents.
154 - work around linux kernel bug (at least in 3.2): kernel might
155 trash fiemap input arguments.
156 - work around linux kernel bug (at least in 3.2): kernel does not
157 set FIEMAP_EXTENT_LAST on last segment.
158 - work around linux kernel bug (at least in 3.2): kernel silently
159 truncates segment count if a file.
160 - make fh argument of IO::AIO::mmap optional, also add mmap/munmap
161 to quick overview.
162 - splice can corrupt data.
163 - (libeio) remove pread/pwrite emulation.
164 - do not grow mmaped scalars in aio_read.

166 - provide pread/pwrite for win32, making it link again on native win32.
167
1684.15 Tue Apr 10 06:59:00 CEST 2012
169 - always include linux/types.h for fiemap, for compatibility to
170 ancient systems (Paul Howarth).
171 - experimental support for IO::AIO::splice and ::tee (no aio_...).
172 - provide SEEK_HOLE and SEEK_DATA, if available.
173 - work around (again!) an immensely stupid bug in RHEL, defining
174 autoconf macros in linux system headers (analysed by Paul Howarth).
175
1764.14 Sat Apr 7 02:45:18 CEST 2012
177 - fix stat structure usage on windows, which caused bogus stat results.

14 - new request aio_fiemap. 180 - new request aio_fiemap.
15 - fix stat structure usage on windows, which caused bogus stat results.

18 182
194.12 Fri Dec 30 08:51:25 CET 2011 1834.12 Fri Dec 30 08:51:25 CET 2011
20 - realpath would return a random value if the name was too long, 184 - realpath would return a random value if the name was too long,
21 instead of -1. 185 instead of -1.
