164.0 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
17 - INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was), 140 - INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
18 see FORK BEHAVIOUR in manpage for details. 141 see FORK BEHAVIOUR in manpage for details.
19 - passes testsuite on win32 now (activetstate 5.10.1). 142 - passes testsuite on win32 now and may actually work
143 (activestate 5.10.1 / MSVC6, YMMV).
20 - (libeio) fix a deadlock where a wakeup signal could be missed when 144 - (libeio) fix a deadlock where a wakeup signal could be missed when
21 a timeout occured at the same time. 145 a timeout occured at the same time.
22 - (libeio) added realpath. 146 - (libeio) added realpath.
23 - (libeio) added fallocate. 147 - (libeio) added fallocate.
