37
38 - add IO::AIO::pipe2 function.
39 - added support for FALLOC_FL_COLLAPSE_RANGE and FALLOC_FL_ZERO_RANGE
40 constants.
41 - added support for O_TMPFILE and O_PATH constants.
42 - use NO_INIT where applicable.
43 - update libecb.
44 - added stability canary support.
45
464.32 Wed Feb 11 20:32:11 CET 2015
47 - replace off_t by STRLEN where appropriate, should not result in
48 user-visible changes.
49 - update ecb.h for C11 compatibility.
50
514.31 Tue Jun 3 03:29:27 CEST 2014
52 - work around more 5.20 bugs. backwards compatibility my ass.
53
544.3 Fri Apr 11 06:22:38 CEST 2014
55 - perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
56 without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
57 in 5.18. What's so attractive about giving a shit about backwards
58 compatibility - I will never understand.
59
604.2 Sat Jan 25 01:13:14 CET 2014
61 - aio_group could corrupt memory because it didn't restore
62 the stack after req_submit.
63 - be more careful on (e.g. permission) errors in bin/treescan.
64 - work around changes in ExtUtils::MakeMaker.
65 - (libeio) implement aio_realpath for win32.
66 - (xthread) work around compile time bugs in ptw32.
67 - added IO::AIO::pipesize.
68 - (libecb) insignificant update.
69
704.19 Sun Jan 6 12:47:26 CET 2013
71 - avoid endless loop in fiemap with some XFS files.
72 - in aio_rename and aio_rmdir, specialcase the case of [$wd, "."]
73 and call rename/rmdir instead of renameat/unlinkat.
74
754.18 Thu Oct 11 07:01:26 CEST 2012
76 - fix unintended xthread_create by intentionalising it :)
77
784.17 Thu Oct 11 05:19:47 CEST 2012
79 - rename aio_fallocate to aio_allocate, to match documentation.
80 - add list of linux fsid values to aio_statvfs docs.
81 - work around a bug in btrfs' FIEMAP ioctl implementation.
82 - work around AIX bug: statvfs.f_fsid is a struct, not unsigned long
83 as per unix spec.
84
854.16 Tue Aug 14 05:39:03 CEST 2012
86 - aio_statvfs was wromgly marked for wd emulation, causing
87 it to malfunction for paths.
88 - fix a crash in aio_fiemap, when used on ranges without any
89 extents.
90 - work around linux kernel bug (at least in 3.2): kernel might
91 trash fiemap input arguments.
92 - work around linux kernel bug (at least in 3.2): kernel does not
93 set FIEMAP_EXTENT_LAST on last segment.
94 - work around linux kernel bug (at least in 3.2): kernel silently
95 truncates segment count if a file.
96 - make fh argument of IO::AIO::mmap optional, also add mmap/munmap
97 to quick overview.
98 - splice can corrupt data.
99 - (libeio) remove pread/pwrite emulation.
100 - do not grow mmaped scalars in aio_read.
101 - add FALLOC_FL_PUNCH_HOLE and document fallocate.
102 - provide pread/pwrite for win32, making it link again on native win32.
103
1044.15 Tue Apr 10 06:59:00 CEST 2012
105 - always include linux/types.h for fiemap, for compatibility to
106 ancient systems (Paul Howarth).
107 - experimental support for IO::AIO::splice and ::tee (no aio_...).
108 - provide SEEK_HOLE and SEEK_DATA, if available.
109 - work around (again!) an immensely stupid bug in RHEL, defining
110 autoconf macros in linux system headers (analysed by Paul Howarth).
111
1124.14 Sat Apr 7 02:45:18 CEST 2012
113 - fix stat structure usage on windows, which caused bogus stat results.
114 - (libeio) make readahead emulation behave more like actual readahead by never failing.
115 - new request aio_seek.
116 - new request aio_fiemap.
117 - autogenerate the #ifdef/#define 0 blocks for symbols we export.
118
1194.12 Fri Dec 30 08:51:25 CET 2011
120 - realpath would return a random value if the name was too long,
121 instead of -1.
122 - port to c89.
123
1244.11 Mon Oct 10 00:24:11 CEST 2011
125 - libeio didn't compile on !linux (Paul Howarth).
126
1274.1 Sun Oct 9 10:24:11 CEST 2011
128 - IO::AIO did access uninitialised memory on unsuccessful stats.
129 - (libeio) added syncfs syscall wrapper.
130 - (libeio) set thread name on linux (ps -L/Hcx, top, gdb).
131 - (libeio) support multiple indepenent working directories.
132 - applied speling corrections by Nicholas Bamber.
133 - tune treescan #threads and #outstanding requests a bit.
134 - reduce the number of file descriptors in use at any one time
135 in treescan, to avoid running out of them (and using too much ram).
136 - take advantage of working directoriy abstractions
137 in aio_scandir and treescan.
138 - reduce compiled size by ~10% by not inlining some key functionality.
139 - added --progress switch to treescan.
140
1414.0 Mon Jul 18 05:01:10 CEST 2011
142 - INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
143 see FORK BEHAVIOUR in manpage for details.
144 - passes testsuite on win32 now and may actually work
145 (activestate 5.10.1 / MSVC6, YMMV).
146 - (libeio) fix a deadlock where a wakeup signal could be missed when
147 a timeout occured at the same time.
148 - (libeio) added realpath.
149 - (libeio) added fallocate.
150 - (libeio) disabling sendfile on darwin unfortunately broke the emulation.
151 - (libeio) do not acquire any locks when forking.
152 - (libeio) use fewer time() syscalls when waiting for new requests.
153
1543.93 Wed Jun 29 23:44:18 CEST 2011
155 - ECB.H WAS MISSING.
156
1573.92 Wed Jun 29 14:45:41 CEST 2011
158 - ecb.h was missing.
159
1603.91 Wed Jun 29 13:24:42 CEST 2011
12 - (libeio) work around a Linux (and likely FreeBSD and other 161 - (libeio) work around a Linux (and likely FreeBSD and other
13 kernels) bug where sendfile would not transfer all the requested 162 kernels) bug where sendfile would not transfer all the requested
14 bytes on large transfers, using a heuristic. 163 bytes on large transfers, using a heuristic.
164 - buggy sendfile caused aio_move/copy to sometimes fail for big
165 files (fortunately it checks that the whole file has been
166 transferred...)
167 - use libecb for higher performance and higher portability.
168 - (libeio) disable sendfile on darwin, it's too broken.
169 - disable fork tests on !linux, as only linux supports mixing
170 pthread and fork in perl.
171 - document the fact that fork doesn't work anymore when using
172 this module, on anything !GNU/Linux.
173 - increase timeout in t/04_fork.t, as too many CPAN-tester setups
174 run on a 0.1MHz cpu. Or so.
