404.53 Tue Aug 14 11:27:50 CEST 2018
41 - add $Config{libs} to LIBS for configure, to work around systems
42 with broken library dependencies (... openbsd).
43
444.52 Sun Aug 12 08:09:45 CEST 2018
45 - config.h.in was missing in distribution.
46
474.51 Sun Aug 12 07:24:14 CEST 2018
48 - complete rework of the autoconf framework: IO::AIO now uses its own
49 config.h, separate from libeio, and tries to test the actual perl
50 environment, not the standard system environment.
51 - provide nanosecond-accracy stat time accessors for both perl and IO::AIO
52 stat functions.
53 - removed non-portable C++ syntax from eio.c.
54 - try to fix readdir tests on cygwin spuriously failing.
55
564.5 Wed Aug 1 00:23:55 CEST 2018
57 - aio_mtouch touch all pages as requested, not just the first page in most cases.
58 - new function: IO::AIO::mremap, linux-specific mremap, with constants MREMAP_MAYMOVE
59 and MREMAP_FIXED.
60 - add O_ACCMODE.
61 - add (undocumented) MSG_CMSG_CLOEXEC and SOCK_CLOEXEC constants.
62
634.4 Tue Feb 20 07:54:12 CET 2018
64 - new aio_slurp request.
65 - add (experimental) IO::AIO::eventfd and timerfd* function.
66 - add (experimental) IO::AIO::get_fdlimit and IO::AIO::min_fdlimit.
67 - point out that aio_copy overwrites existing files.
68 - removed filesystem magic number table from aio_statvfs docs as
69 statvfs doesn't actually return this info at all (statfs does).
70 - add a bunch of (mostly linux-specific) constants for use in ioctls
71 (see aio_ioctl docs).
72 - treescan now has a proper manpage and useful --help output.
73 - new option --sync in treescan, to sync everything in a subtree.
74 - changed default for aio_msync flags to MSYNC_SYNC.
75 - document offset/length behaviour of mprotect/madvise.
76 - support linux's renameat2 (via aio_rename2).
77 - add aio_rename2, an aio_rename with flags.
78 - add F_DUPPFD_CLOEXEC, F_OFD_[SG]ETLKW? constants.
79 - add FALLOC_FL_INSERT_RANGE, FALLOC_FL_UNSHARE_RANGE.
80 - (libeio) use posix_close if available.
81 - (libeio) internal close() calls no longer disturb errno.
82 - add IO:AIO::FALLOC_FL_UNSHARE.
83 - update schmorp.h for removal of USE_SOCKETS_AS_HANDLES
84 and better eventfd detection.
85
864.34 Sun May 1 19:18:24 CEST 2016
87 - def0.h was not properly generated during previous release, causing
88 compile errors on various platforms.
89 - major/minor were accidentally switched (reported by Alexander Lishenyuk).
90 - removed duplicate definition of MAP_HUGETLB, that was found due to
91 a bug in Perl::Tidy (testcase by alaska332@gmail.com).
92 - added (untested!) aio_fcntl, aio_ioctl requests.
93 - (libeio) names set via prctl are truncated to 15 chars + nul, not 16,
94 as manpages-dev originally claimed.
95
964.33 Mon Jan 18 12:50:10 CET 2016
97 - add IO::AIO::pipe2 function.
98 - added support for FALLOC_FL_COLLAPSE_RANGE and FALLOC_FL_ZERO_RANGE
99 constants.
100 - added support for O_TMPFILE and O_PATH constants.
101 - added support for MAP_FIXED, MAP_GROWSDOWN,MAP_32BIT, MAP_HUGETLB, MAP_STACK
102 consdtants, whether they can be sensibly used or not.
103 - use NO_INIT where applicable.
104 - update libecb.
105 - added stability canary support.
106 - updated linux super magic table to 4.3.3.
107
1084.32 Wed Feb 11 20:32:11 CET 2015
109 - replace off_t by STRLEN where appropriate, should not result in
110 user-visible changes.
111 - update ecb.h for C11 compatibility.
112
1134.31 Tue Jun 3 03:29:27 CEST 2014
114 - work around more 5.20 bugs. backwards compatibility my ass.
115
1164.3 Fri Apr 11 06:22:38 CEST 2014
117 - perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
118 without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
119 in 5.18. What's so attractive about giving a shit about backwards
120 compatibility - I will never understand.
121
1224.2 Sat Jan 25 01:13:14 CET 2014
123 - aio_group could corrupt memory because it didn't restore
124 the stack after req_submit.
125 - be more careful on (e.g. permission) errors in bin/treescan.
126 - work around changes in ExtUtils::MakeMaker.
13 - (libeio) implement aio_realpath for win32. 127 - (libeio) implement aio_realpath for win32.
14 - (xthread) work around compile time bugs in ptw32. 128 - (xthread) work around compile time bugs in ptw32.

17 - avoid endless loop in fiemap with some XFS files. 133 - avoid endless loop in fiemap with some XFS files.
18 - in aio_rename and aio_rmdir, specialcase the case of [$wd, "."] 134 - in aio_rename and aio_rmdir, specialcase the case of [$wd, "."]
19 and call rename/rmdir instead of renameat/unlinkat. 135 and call rename/rmdir instead of renameat/unlinkat.
