46
474.34 Sun May 1 19:18:24 CEST 2016
48 - def0.h was not properly generated during previous release, causing
49 compile errors on various platforms.
50 - major/minor were accidentally switched (reported by Alexander Lishenyuk).
51 - removed duplicate definition of MAP_HUGETLB, that was found due to
52 a bug in Perl::Tidy (testcase by alaska332@gmail.com).
53 - added (untested!) aio_fcntl, aio_ioctl requests.
54 - (libeio) names set via prctl are truncated to 15 chars + nul, not 16,
55 as manpages-dev originally claimed.
56
574.33 Mon Jan 18 12:50:10 CET 2016
58 - add IO::AIO::pipe2 function.
59 - added support for FALLOC_FL_COLLAPSE_RANGE and FALLOC_FL_ZERO_RANGE
60 constants.
61 - added support for O_TMPFILE and O_PATH constants.
62 - added support for MAP_FIXED, MAP_GROWSDOWN,MAP_32BIT, MAP_HUGETLB, MAP_STACK

68
694.32 Wed Feb 11 20:32:11 CET 2015

75 - work around more 5.20 bugs. backwards compatibility my ass.
76
774.3 Fri Apr 11 06:22:38 CEST 2014
78 - perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
79 without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
80 in 5.18. What's so attractive about giving a shit about backwards
81 compatibility - I will never understand.
82
834.2 Sat Jan 25 01:13:14 CET 2014
84 - aio_group could corrupt memory because it didn't restore
85 the stack after req_submit.

103 - add list of linux fsid values to aio_statvfs docs.
104 - work around a bug in btrfs' FIEMAP ioctl implementation.
105 - work around AIX bug: statvfs.f_fsid is a struct, not unsigned long
106 as per unix spec.
107
1084.16 Tue Aug 14 05:39:03 CEST 2012
109 - aio_statvfs was wromgly marked for wd emulation, causing
110 it to malfunction for paths.
111 - fix a crash in aio_fiemap, when used on ranges without any
112 extents.
113 - work around linux kernel bug (at least in 3.2): kernel might
114 trash fiemap input arguments.
115 - work around linux kernel bug (at least in 3.2): kernel does not
116 set FIEMAP_EXTENT_LAST on last segment.
117 - work around linux kernel bug (at least in 3.2): kernel silently
118 truncates segment count if a file.
119 - make fh argument of IO::AIO::mmap optional, also add mmap/munmap
120 to quick overview.
121 - splice can corrupt data.

126
1274.15 Tue Apr 10 06:59:00 CEST 2012
128 - always include linux/types.h for fiemap, for compatibility to
129 ancient systems (Paul Howarth).
130 - experimental support for IO::AIO::splice and ::tee (no aio_...).
131 - provide SEEK_HOLE and SEEK_DATA, if available.
132 - work around (again!) an immensely stupid bug in RHEL, defining
133 autoconf macros in linux system headers (analysed by Paul Howarth).
134
1354.14 Sat Apr 7 02:45:18 CEST 2012
136 - fix stat structure usage on windows, which caused bogus stat results.
137 - (libeio) make readahead emulation behave more like actual readahead by never failing.
138 - new request aio_seek.
139 - new request aio_fiemap.
140 - autogenerate the #ifdef/#define 0 blocks for symbols we export.
141
1424.12 Fri Dec 30 08:51:25 CET 2011
143 - realpath would return a random value if the name was too long,
144 instead of -1.
145 - port to c89.
146
1474.11 Mon Oct 10 00:24:11 CEST 2011
148 - libeio didn't compile on !linux (Paul Howarth).
149
1504.1 Sun Oct 9 10:24:11 CEST 2011
151 - IO::AIO did access uninitialised memory on unsuccessful stats.
152 - (libeio) added syncfs syscall wrapper.
153 - (libeio) set thread name on linux (ps -L/Hcx, top, gdb).
154 - (libeio) support multiple indepenent working directories.
155 - applied speling corrections by Nicholas Bamber.
156 - tune treescan #threads and #outstanding requests a bit.
157 - reduce the number of file descriptors in use at any one time
158 in treescan, to avoid running out of them (and using too much ram).
159 - take advantage of working directoriy abstractions
160 in aio_scandir and treescan.
161 - reduce compiled size by ~10% by not inlining some key functionality.
162 - added --progress switch to treescan.
163
1644.0 Mon Jul 18 05:01:10 CEST 2011
165 - INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
166 see FORK BEHAVIOUR in manpage for details.
167 - passes testsuite on win32 now and may actually work
168 (activestate 5.10.1 / MSVC6, YMMV).
169 - (libeio) fix a deadlock where a wakeup signal could be missed when
170 a timeout occured at the same time.
171 - (libeio) added realpath.
172 - (libeio) added fallocate.
173 - (libeio) disabling sendfile on darwin unfortunately broke the emulation.
174 - (libeio) do not acquire any locks when forking.
175 - (libeio) use fewer time() syscalls when waiting for new requests.
176
1773.93 Wed Jun 29 23:44:18 CEST 2011
178 - ECB.H WAS MISSING.
179
1803.92 Wed Jun 29 14:45:41 CEST 2011
181 - ecb.h was missing.
182
1833.91 Wed Jun 29 13:24:42 CEST 2011
184 - (libeio) work around a Linux (and likely FreeBSD and other
185 kernels) bug where sendfile would not transfer all the requested
186 bytes on large transfers, using a heuristic.
187 - buggy sendfile caused aio_move/copy to sometimes fail for big
188 files (fortunately it checks that the whole file has been
189 transferred...)
190 - use libecb for higher performance and higher portability.
191 - (libeio) disable sendfile on darwin, it's too broken.
192 - disable fork tests on !linux, as only linux supports mixing
193 pthread and fork in perl.
194 - document the fact that fork doesn't work anymore when using
195 this module, on anything !GNU/Linux.
196 - increase timeout in t/04_fork.t, as too many CPAN-tester setups
197 run on a 0.1MHz cpu. Or so.
198
1993.9 Fri May 27 02:43:47 CEST 2011
200 - (libeio) fix memory corruption in aio_readdirx for the flags
201 combination READDIR_STAT_ORDER | READDIR_DIRS_FIRST.
202 - add lots of newer POSIX and GNU/Linux-specific open
203 flags.
204
2053.8 Sun Mar 27 12:25:33 CEST 2011
206 - use nonstandard but maybe-working-on-bsd fork technique.
207 - support a max_idle value of 0.
208 - support setting of idle timeout value (IO::AIO::idle_timeout).
209
2103.72 Fri Feb 11 04:25:38 CET 2011
211 - use _POSIX_MEMLOCK_RANGE to detect mlock/munlock.
212 - aio_mknod always used a dev_t value of 0.
213 - new treescan option: --grep.
214 - add more S_IF macros, and major/minor/makedev "macros".
215
2163.71 Thu Dec 30 08:18:46 CET 2010
217 - the numerical result value passed to callbacks did not stringify
218 correctly, due to internal reuse and failure to reset the sv flags.
219 - actually test for posix_[mf]advise, as at least uClibc defines
220 _POSIX_ADVISORY_INFO without actually having any of the required
221 funcitonality. ugh.
222
2233.7 Mon Nov 1 23:00:34 CET 2010
224 - implement/add madvise, mmap, munmap, aio_mlockall, munlockall,
225 aio_mlock, munlock, msync and mtouch to @EXPORT_OK.
226 - document the sad state of affairs w.r.t. pthread on many bsds.
227 - do not enable mmap on systems without _POSIX_MAPPED_FILES
228 (openbsd 4.8).
229 - do not leak memory in IO::AIO::mmap when the scalar already
230 had string-data.
231 - add O_RDWR, O_APPEND and O_EXCL symbols and semi-document
232 them.
233 - cache the result IV, for a minor speedup in the common case.
234 - croak when an mmapped-scalar changes location, to detect
235 user-errors better.
236 - fix aio_readlink prototype.
237
2383.65 Wed Mar 31 02:45:05 CEST 2010
239 - actually use PATH_MAX instead of NAME_MAX for readlink, as to not
240 cut off long pathnames in aio_readlink (based on patch by
241 Rasmus Andersson).
242 - a double fork partially killed the event pipe (great testcase
243 by dormando). affects IO::AIO, BDB and Async::Interrupt.
244 - suck steve's dick and rename our symbols to avoid colliding
245 with nonstandard identifier spam on the broken os x pseudo-os.
246 affects IO::AIO and BDB.
247
2483.6 Mon Jan 11 00:43:39 CET 2010
11 - (libeio) more fixes for the freebsd/apple sendfile - broken by 249 - (libeio) more fixes for the freebsd/apple sendfile - broken by
12 manpage standards, but apparently correct accoridng to actual 250 manpage standards, but apparently correct accoridng to actual
13 kernel sources. 251 kernel sources.
252 - add IO::AIO::mmap/munmap support.
