37
38 - use NO_INIT where applicable.
39 - update libecb.
40 - added stability canary support.
41 - added support for FALLOC_FL_COLLAPSE_RANGE and FALLOC_FL_ZERO_RANGE
42 constants.
43
444.32 Wed Feb 11 20:32:11 CET 2015
45 - replace off_t by STRLEN where appropriate, should not result in
46 user-visible changes.
47 - update ecb.h for C11 compatibility.
48
494.31 Tue Jun 3 03:29:27 CEST 2014
50 - work around more 5.20 bugs. backwards compatibility my ass.
51
524.3 Fri Apr 11 06:22:38 CEST 2014
53 - perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
54 without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
55 in 5.18. What's so attractive about giving a shit about backwards
56 compatibility - I will never understand.
57
584.2 Sat Jan 25 01:13:14 CET 2014
59 - aio_group could corrupt memory because it didn't restore
60 the stack after req_submit.
61 - be more careful on (e.g. permission) errors in bin/treescan.
62 - work around changes in ExtUtils::MakeMaker.
63 - (libeio) implement aio_realpath for win32.
64 - (xthread) work around compile time bugs in ptw32.
65 - added IO::AIO::pipesize.
66 - (libecb) insignificant update.
67
684.19 Sun Jan 6 12:47:26 CET 2013
69 - avoid endless loop in fiemap with some XFS files.
70 - in aio_rename and aio_rmdir, specialcase the case of [$wd, "."]
71 and call rename/rmdir instead of renameat/unlinkat.
72
734.18 Thu Oct 11 07:01:26 CEST 2012
74 - fix unintended xthread_create by intentionalising it :)
75
764.17 Thu Oct 11 05:19:47 CEST 2012
77 - rename aio_fallocate to aio_allocate, to match documentation.
78 - add list of linux fsid values to aio_statvfs docs.
79 - work around a bug in btrfs' FIEMAP ioctl implementation.
80 - work around AIX bug: statvfs.f_fsid is a struct, not unsigned long
81 as per unix spec.
82
834.16 Tue Aug 14 05:39:03 CEST 2012
84 - aio_statvfs was wromgly marked for wd emulation, causing
85 it to malfunction for paths.
86 - fix a crash in aio_fiemap, when used on ranges without any
87 extents.
88 - work around linux kernel bug (at least in 3.2): kernel might
89 trash fiemap input arguments.
90 - work around linux kernel bug (at least in 3.2): kernel does not
91 set FIEMAP_EXTENT_LAST on last segment.
92 - work around linux kernel bug (at least in 3.2): kernel silently
93 truncates segment count if a file.
94 - make fh argument of IO::AIO::mmap optional, also add mmap/munmap
95 to quick overview.
96 - splice can corrupt data.
97 - (libeio) remove pread/pwrite emulation.
98 - do not grow mmaped scalars in aio_read.
99 - add FALLOC_FL_PUNCH_HOLE and document fallocate.
100 - provide pread/pwrite for win32, making it link again on native win32.
101
1024.15 Tue Apr 10 06:59:00 CEST 2012
103 - always include linux/types.h for fiemap, for compatibility to
104 ancient systems (Paul Howarth).
105 - experimental support for IO::AIO::splice and ::tee (no aio_...).
106 - provide SEEK_HOLE and SEEK_DATA, if available.
107 - work around (again!) an immensely stupid bug in RHEL, defining
108 autoconf macros in linux system headers (analysed by Paul Howarth).
109
1104.14 Sat Apr 7 02:45:18 CEST 2012
111 - fix stat structure usage on windows, which caused bogus stat results.
112 - (libeio) make readahead emulation behave more like actual readahead by never failing.
113 - new request aio_seek.
114 - new request aio_fiemap.
115 - autogenerate the #ifdef/#define 0 blocks for symbols we export.
116
1174.12 Fri Dec 30 08:51:25 CET 2011
118 - realpath would return a random value if the name was too long,
119 instead of -1.
120 - port to c89.
121
1224.11 Mon Oct 10 00:24:11 CEST 2011
123 - libeio didn't compile on !linux (Paul Howarth).
124
1254.1 Sun Oct 9 10:24:11 CEST 2011
126 - IO::AIO did access uninitialised memory on unsuccessful stats.
127 - (libeio) added syncfs syscall wrapper.
128 - (libeio) set thread name on linux (ps -L/Hcx, top, gdb).
129 - (libeio) support multiple indepenent working directories.
130 - applied speling corrections by Nicholas Bamber.
131 - tune treescan #threads and #outstanding requests a bit.
132 - reduce the number of file descriptors in use at any one time
133 in treescan, to avoid running out of them (and using too much ram).
134 - take advantage of working directoriy abstractions
135 in aio_scandir and treescan.
136 - reduce compiled size by ~10% by not inlining some key functionality.
137 - added --progress switch to treescan.
138
1394.0 Mon Jul 18 05:01:10 CEST 2011
140 - INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
141 see FORK BEHAVIOUR in manpage for details.
142 - passes testsuite on win32 now and may actually work
143 (activestate 5.10.1 / MSVC6, YMMV).
144 - (libeio) fix a deadlock where a wakeup signal could be missed when
145 a timeout occured at the same time.
146 - (libeio) added realpath.
147 - (libeio) added fallocate.
148 - (libeio) disabling sendfile on darwin unfortunately broke the emulation.
149 - (libeio) do not acquire any locks when forking.
150 - (libeio) use fewer time() syscalls when waiting for new requests.
151
1523.93 Wed Jun 29 23:44:18 CEST 2011

157
1583.91 Wed Jun 29 13:24:42 CEST 2011
14 - (libeio) work around a Linux (and likely FreeBSD and other 159 - (libeio) work around a Linux (and likely FreeBSD and other
15 kernels) bug where sendfile would not transfer all the requested 160 kernels) bug where sendfile would not transfer all the requested
16 bytes on large transfers, using a heuristic. 161 bytes on large transfers, using a heuristic.
17 - buggy sendfile caused aio_move/copy to sometimes fail for big 162 - buggy sendfile caused aio_move/copy to sometimes fail for big
18 files (fortunately it vchecks that the whole file has been 163 files (fortunately it checks that the whole file has been
19 transferred...) 164 transferred...)
20 - use libecb for higher performance and higher portability. 165 - use libecb for higher performance and higher portability.
166 - (libeio) disable sendfile on darwin, it's too broken.
167 - disable fork tests on !linux, as only linux supports mixing
168 pthread and fork in perl.
169 - document the fact that fork doesn't work anymore when using
170 this module, on anything !GNU/Linux.
171 - increase timeout in t/04_fork.t, as too many CPAN-tester setups
172 run on a 0.1MHz cpu. Or so.

24 combination READDIR_STAT_ORDER | READDIR_DIRS_FIRST. 176 combination READDIR_STAT_ORDER | READDIR_DIRS_FIRST.
25 - add lots of newre POSIX and GNU/Linux-specific open 177 - add lots of newer POSIX and GNU/Linux-specific open
