254.3 Fri Apr 11 06:22:38 CEST 2014
26 - perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
27 without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
28 in 5.18. What's so attractive about giving a shit about backwards
29 compatibility - I will never understand.
30
314.2 Sat Jan 25 01:13:14 CET 2014
32 - aio_group could corrupt memory because it didn't restore
33 the stack after req_submit.
34 - be more careful on (e.g. permission) errors in bin/treescan.
35 - work around changes in ExtUtils::MakeMaker.
36 - (libeio) implement aio_realpath for win32.
37 - (xthread) work around compile time bugs in ptw32.
38 - added IO::AIO::pipesize.
39 - (libecb) insignificant update.
40
414.19 Sun Jan 6 12:47:26 CET 2013
42 - avoid endless loop in fiemap with some XFS files.
43 - in aio_rename and aio_rmdir, specialcase the case of [$wd, "."]
44 and call rename/rmdir instead of renameat/unlinkat.
45
464.18 Thu Oct 11 07:01:26 CEST 2012
47 - fix unintended xthread_create by intentionalising it :)
48
494.17 Thu Oct 11 05:19:47 CEST 2012
50 - rename aio_fallocate to aio_allocate, to match documentation.
51 - add list of linux fsid values to aio_statvfs docs.
52 - work around a bug in btrfs' FIEMAP ioctl implementation.
53 - work around AIX bug: statvfs.f_fsid is a struct, not unsigned long
54 as per unix spec.
55
564.16 Tue Aug 14 05:39:03 CEST 2012
57 - aio_statvfs was wromgly marked for wd emulation, causing
58 it to malfunction for paths.
59 - fix a crash in aio_fiemap, when used on ranges without any
60 extents.
61 - work around linux kernel bug (at least in 3.2): kernel might
62 trash fiemap input arguments.
63 - work around linux kernel bug (at least in 3.2): kernel does not
64 set FIEMAP_EXTENT_LAST on last segment.
65 - work around linux kernel bug (at least in 3.2): kernel silently
66 truncates segment count if a file.
67 - make fh argument of IO::AIO::mmap optional, also add mmap/munmap
68 to quick overview.
69 - splice can corrupt data.
70 - (libeio) remove pread/pwrite emulation.
71 - do not grow mmaped scalars in aio_read.
72 - add FALLOC_FL_PUNCH_HOLE and document fallocate.
73 - provide pread/pwrite for win32, making it link again on native win32.
74
754.15 Tue Apr 10 06:59:00 CEST 2012
76 - always include linux/types.h for fiemap, for compatibility to
77 ancient systems (Paul Howarth).
78 - experimental support for IO::AIO::splice and ::tee (no aio_...).
79 - provide SEEK_HOLE and SEEK_DATA, if available.
80 - work around (again!) an immensely stupid bug in RHEL, defining
81 autoconf macros in linux system headers (analysed by Paul Howarth).
82
834.14 Sat Apr 7 02:45:18 CEST 2012
84 - fix stat structure usage on windows, which caused bogus stat results.
85 - (libeio) make readahead emulation behave more like actual readahead by never failing.
86 - new request aio_seek.
87 - new request aio_fiemap.
88 - autogenerate the #ifdef/#define 0 blocks for symbols we export.
89
904.12 Fri Dec 30 08:51:25 CET 2011
91 - realpath would return a random value if the name was too long,
92 instead of -1.
93 - port to c89.
94
954.11 Mon Oct 10 00:24:11 CEST 2011
96 - libeio didn't compile on !linux (Paul Howarth).
97
984.1 Sun Oct 9 10:24:11 CEST 2011
99 - IO::AIO did access uninitialised memory on unsuccessful stats.
100 - (libeio) added syncfs syscall wrapper.
101 - (libeio) set thread name on linux (ps -L/Hcx, top, gdb).
102 - (libeio) support multiple indepenent working directories.
103 - applied speling corrections by Nicholas Bamber.
104 - tune treescan #threads and #outstanding requests a bit.
105 - reduce the number of file descriptors in use at any one time
106 in treescan, to avoid running out of them (and using too much ram).
107 - take advantage of working directoriy abstractions
108 in aio_scandir and treescan.
109 - reduce compiled size by ~10% by not inlining some key functionality.
110 - added --progress switch to treescan.
111
1124.0 Mon Jul 18 05:01:10 CEST 2011
113 - INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
114 see FORK BEHAVIOUR in manpage for details.
115 - passes testsuite on win32 now and may actually work
116 (activestate 5.10.1 / MSVC6, YMMV).
117 - (libeio) fix a deadlock where a wakeup signal could be missed when
118 a timeout occured at the same time.
119 - (libeio) added realpath.
120 - (libeio) added fallocate.
121 - (libeio) disabling sendfile on darwin unfortunately broke the emulation.
122 - (libeio) do not acquire any locks when forking.
123 - (libeio) use fewer time() syscalls when waiting for new requests.
124
1253.93 Wed Jun 29 23:44:18 CEST 2011
126 - ECB.H WAS MISSING.
127
1283.92 Wed Jun 29 14:45:41 CEST 2011
129 - ecb.h was missing.
130
1313.91 Wed Jun 29 13:24:42 CEST 2011
132 - (libeio) work around a Linux (and likely FreeBSD and other
133 kernels) bug where sendfile would not transfer all the requested
134 bytes on large transfers, using a heuristic.
135 - buggy sendfile caused aio_move/copy to sometimes fail for big
136 files (fortunately it checks that the whole file has been
137 transferred...)
138 - use libecb for higher performance and higher portability.
139 - (libeio) disable sendfile on darwin, it's too broken.
140 - disable fork tests on !linux, as only linux supports mixing
141 pthread and fork in perl.
142 - document the fact that fork doesn't work anymore when using
143 this module, on anything !GNU/Linux.
144 - increase timeout in t/04_fork.t, as too many CPAN-tester setups
145 run on a 0.1MHz cpu. Or so.
146
1473.9 Fri May 27 02:43:47 CEST 2011
148 - (libeio) fix memory corruption in aio_readdirx for the flags
149 combination READDIR_STAT_ORDER | READDIR_DIRS_FIRST.
150 - add lots of newer POSIX and GNU/Linux-specific open
151 flags.
152
1533.8 Sun Mar 27 12:25:33 CEST 2011
154 - use nonstandard but maybe-working-on-bsd fork technique.
155 - support a max_idle value of 0.
156 - support setting of idle timeout value (IO::AIO::idle_timeout).
157
1583.72 Fri Feb 11 04:25:38 CET 2011
159 - use _POSIX_MEMLOCK_RANGE to detect mlock/munlock.
160 - aio_mknod always used a dev_t value of 0.
161 - new treescan option: --grep.
162 - add more S_IF macros, and major/minor/makedev "macros".
163
1643.71 Thu Dec 30 08:18:46 CET 2010
165 - the numerical result value passed to callbacks did not stringify
166 correctly, due to internal reuse and failure to reset the sv flags.
167 - actually test for posix_[mf]advise, as at least uClibc defines
168 _POSIX_ADVISORY_INFO without actually having any of the required
169 funcitonality. ugh.
170
1713.7 Mon Nov 1 23:00:34 CET 2010
172 - implement/add madvise, mmap, munmap, aio_mlockall, munlockall,
173 aio_mlock, munlock, msync and mtouch to @EXPORT_OK.
174 - document the sad state of affairs w.r.t. pthread on many bsds.
175 - do not enable mmap on systems without _POSIX_MAPPED_FILES
176 (openbsd 4.8).
24 - do not leak memory in IO::AIO::mmap when the scalar already 177 - do not leak memory in IO::AIO::mmap when the scalar already
25 had string-data. 178 had string-data.
26 - add O_RDWR, O_APPEND and O_EXCL symbols and semi-documented 179 - add O_RDWR, O_APPEND and O_EXCL symbols and semi-document
27 them. 180 them.
28 - cache the result IV, for a minor speedup in the common case. 181 - cache the result IV, for a minor speedup in the common case.
29 - croak when an mmapped-scalar changes location, to detect 182 - croak when an mmapped-scalar changes location, to detect
30 user-errors better. 183 user-errors better.
184 - fix aio_readlink prototype.

323.65 Wed Mar 31 02:45:05 CEST 2010 1863.65 Wed Mar 31 02:45:05 CEST 2010
33 - actually use PATH_MAX instead of NAME_MAX for readlink, as to not 187 - actually use PATH_MAX instead of NAME_MAX for readlink, as to not
34 cut off long pathnames in aio_readlink (based on patch by 188 cut off long pathnames in aio_readlink (based on patch by
35 Rasmus Andersson). 189 Rasmus Andersson).
