43 constants.
44
454.32 Wed Feb 11 20:32:11 CET 2015
46 - replace off_t by STRLEN where appropriate, should not result in
47 user-visible changes.
48 - update ecb.h for C11 compatibility.
49
504.31 Tue Jun 3 03:29:27 CEST 2014
51 - work around more 5.20 bugs. backwards compatibility my ass.
52
534.3 Fri Apr 11 06:22:38 CEST 2014
54 - perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
55 without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
56 in 5.18. What's so attractive about giving a shit about backwards
57 compatibility - I will never understand.
58
594.2 Sat Jan 25 01:13:14 CET 2014
60 - aio_group could corrupt memory because it didn't restore
61 the stack after req_submit.
62 - be more careful on (e.g. permission) errors in bin/treescan.
63 - work around changes in ExtUtils::MakeMaker.
64 - (libeio) implement aio_realpath for win32.
65 - (xthread) work around compile time bugs in ptw32.
66 - added IO::AIO::pipesize.
67 - (libecb) insignificant update.
68
694.19 Sun Jan 6 12:47:26 CET 2013
70 - avoid endless loop in fiemap with some XFS files.
71 - in aio_rename and aio_rmdir, specialcase the case of [$wd, "."]
72 and call rename/rmdir instead of renameat/unlinkat.
73
744.18 Thu Oct 11 07:01:26 CEST 2012
75 - fix unintended xthread_create by intentionalising it :)
76
774.17 Thu Oct 11 05:19:47 CEST 2012
78 - rename aio_fallocate to aio_allocate, to match documentation.
79 - add list of linux fsid values to aio_statvfs docs.
80 - work around a bug in btrfs' FIEMAP ioctl implementation.
81 - work around AIX bug: statvfs.f_fsid is a struct, not unsigned long
82 as per unix spec.
83
844.16 Tue Aug 14 05:39:03 CEST 2012
85 - aio_statvfs was wromgly marked for wd emulation, causing
86 it to malfunction for paths.
87 - fix a crash in aio_fiemap, when used on ranges without any
88 extents.
89 - work around linux kernel bug (at least in 3.2): kernel might
90 trash fiemap input arguments.
91 - work around linux kernel bug (at least in 3.2): kernel does not
92 set FIEMAP_EXTENT_LAST on last segment.
93 - work around linux kernel bug (at least in 3.2): kernel silently
94 truncates segment count if a file.
95 - make fh argument of IO::AIO::mmap optional, also add mmap/munmap
96 to quick overview.
97 - splice can corrupt data.
98 - (libeio) remove pread/pwrite emulation.
99 - do not grow mmaped scalars in aio_read.
100 - add FALLOC_FL_PUNCH_HOLE and document fallocate.
101 - provide pread/pwrite for win32, making it link again on native win32.
102
1034.15 Tue Apr 10 06:59:00 CEST 2012
104 - always include linux/types.h for fiemap, for compatibility to
105 ancient systems (Paul Howarth).
106 - experimental support for IO::AIO::splice and ::tee (no aio_...).
107 - provide SEEK_HOLE and SEEK_DATA, if available.
108 - work around (again!) an immensely stupid bug in RHEL, defining
109 autoconf macros in linux system headers (analysed by Paul Howarth).
110
1114.14 Sat Apr 7 02:45:18 CEST 2012
112 - fix stat structure usage on windows, which caused bogus stat results.
113 - (libeio) make readahead emulation behave more like actual readahead by never failing.
114 - new request aio_seek.
115 - new request aio_fiemap.
116 - autogenerate the #ifdef/#define 0 blocks for symbols we export.
117
1184.12 Fri Dec 30 08:51:25 CET 2011
119 - realpath would return a random value if the name was too long,
120 instead of -1.
121 - port to c89.
122
1234.11 Mon Oct 10 00:24:11 CEST 2011
124 - libeio didn't compile on !linux (Paul Howarth).
125
1264.1 Sun Oct 9 10:24:11 CEST 2011
127 - IO::AIO did access uninitialised memory on unsuccessful stats.
128 - (libeio) added syncfs syscall wrapper.
129 - (libeio) set thread name on linux (ps -L/Hcx, top, gdb).
130 - (libeio) support multiple indepenent working directories.
131 - applied speling corrections by Nicholas Bamber.
132 - tune treescan #threads and #outstanding requests a bit.
133 - reduce the number of file descriptors in use at any one time
134 in treescan, to avoid running out of them (and using too much ram).
135 - take advantage of working directoriy abstractions
136 in aio_scandir and treescan.
137 - reduce compiled size by ~10% by not inlining some key functionality.
138 - added --progress switch to treescan.
139
1404.0 Mon Jul 18 05:01:10 CEST 2011
141 - INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
142 see FORK BEHAVIOUR in manpage for details.
143 - passes testsuite on win32 now and may actually work
144 (activestate 5.10.1 / MSVC6, YMMV).
145 - (libeio) fix a deadlock where a wakeup signal could be missed when
146 a timeout occured at the same time.
147 - (libeio) added realpath.
148 - (libeio) added fallocate.
149 - (libeio) disabling sendfile on darwin unfortunately broke the emulation.
150 - (libeio) do not acquire any locks when forking.
151 - (libeio) use fewer time() syscalls when waiting for new requests.
152
1533.93 Wed Jun 29 23:44:18 CEST 2011
154 - ECB.H WAS MISSING.
155
1563.92 Wed Jun 29 14:45:41 CEST 2011
157 - ecb.h was missing.
158
1593.91 Wed Jun 29 13:24:42 CEST 2011
160 - (libeio) work around a Linux (and likely FreeBSD and other
161 kernels) bug where sendfile would not transfer all the requested
162 bytes on large transfers, using a heuristic.
163 - buggy sendfile caused aio_move/copy to sometimes fail for big
164 files (fortunately it checks that the whole file has been
165 transferred...)
166 - use libecb for higher performance and higher portability.
167 - (libeio) disable sendfile on darwin, it's too broken.
168 - disable fork tests on !linux, as only linux supports mixing
169 pthread and fork in perl.
170 - document the fact that fork doesn't work anymore when using
171 this module, on anything !GNU/Linux.
172 - increase timeout in t/04_fork.t, as too many CPAN-tester setups
173 run on a 0.1MHz cpu. Or so.
174
1753.9 Fri May 27 02:43:47 CEST 2011
176 - (libeio) fix memory corruption in aio_readdirx for the flags
177 combination READDIR_STAT_ORDER | READDIR_DIRS_FIRST.
178 - add lots of newer POSIX and GNU/Linux-specific open
179 flags.
180
1813.8 Sun Mar 27 12:25:33 CEST 2011
182 - use nonstandard but maybe-working-on-bsd fork technique.
183 - support a max_idle value of 0.
184 - support setting of idle timeout value (IO::AIO::idle_timeout).
185
1863.72 Fri Feb 11 04:25:38 CET 2011
187 - use _POSIX_MEMLOCK_RANGE to detect mlock/munlock.
188 - aio_mknod always used a dev_t value of 0.
189 - new treescan option: --grep.
190 - add more S_IF macros, and major/minor/makedev "macros".
191
1923.71 Thu Dec 30 08:18:46 CET 2010
193 - the numerical result value passed to callbacks did not stringify
194 correctly, due to internal reuse and failure to reset the sv flags.
195 - actually test for posix_[mf]advise, as at least uClibc defines
196 _POSIX_ADVISORY_INFO without actually having any of the required
197 funcitonality. ugh.
198
1993.7 Mon Nov 1 23:00:34 CET 2010
200 - implement/add madvise, mmap, munmap, aio_mlockall, munlockall,
201 aio_mlock, munlock, msync and mtouch to @EXPORT_OK.
202 - document the sad state of affairs w.r.t. pthread on many bsds.
203 - do not enable mmap on systems without _POSIX_MAPPED_FILES
204 (openbsd 4.8).
205 - do not leak memory in IO::AIO::mmap when the scalar already
206 had string-data.
207 - add O_RDWR, O_APPEND and O_EXCL symbols and semi-document
208 them.
209 - cache the result IV, for a minor speedup in the common case.
210 - croak when an mmapped-scalar changes location, to detect
211 user-errors better.
212 - fix aio_readlink prototype.
213
2143.65 Wed Mar 31 02:45:05 CEST 2010
215 - actually use PATH_MAX instead of NAME_MAX for readlink, as to not
216 cut off long pathnames in aio_readlink (based on patch by
217 Rasmus Andersson).
218 - a double fork partially killed the event pipe (great testcase
219 by dormando). affects IO::AIO, BDB and Async::Interrupt.
220 - suck steve's dick and rename our symbols to avoid colliding
221 with nonstandard identifier spam on the broken os x pseudo-os.
222 affects IO::AIO and BDB.
223
2243.6 Mon Jan 11 00:43:39 CET 2010
11 - (libeio) more fixes for the freebsd/apple sendfile - it should now 225 - (libeio) more fixes for the freebsd/apple sendfile - broken by
12 be correct according to the manpage, but it seems to be broken by 226 manpage standards, but apparently correct accoridng to actual
13 design, failing to account some bytes sometimes. 227 kernel sources.
228 - add IO::AIO::mmap/munmap support.
229 - add IO::AIO::m(un)lockall support.
230 - clean up manpage.
14 231
153.5 Thu Jan 7 21:25:04 CET 2010 2323.5 Thu Jan 7 21:25:04 CET 2010
16 - (liebio) fix freebsd sendfile (Vanilla Hsu). 233 - (liebio) fix freebsd sendfile (Vanilla Hsu).
17 - (libeio) also fix darwin sendfile that suffered from a similar bug. 234 - (libeio) also fix darwin sendfile that suffered from a similar bug.
18 - add aio_statvfs as interface to statvfs/fstatvfs. 235 - add aio_statvfs as interface to statvfs/fstatvfs.
