24TODO: extra socket/tcp constants &c?
25TODO: take permission denied into account in treescan
26 - aio_group could corrupt memory because it didn't restore
27 the stack after req_submit.
28 - work around changes in ExtUtils::MakeMaker.
29 - (libeio) implement aio_realpath for win32.
30 - (xthread) work around compile time bugs in ptw32.
31 - added IO::AIO::pipesize.
32 - (libecb) insignificant update.
33
344.19 Sun Jan 6 12:47:26 CET 2013
35 - avoid endless loop in fiemap with some XFS files.
36 - in aio_rename and aio_rmdir, specialcase the case of [$wd, "."]
37 and call rename/rmdir instead of renameat/unlinkat.
38
394.18 Thu Oct 11 07:01:26 CEST 2012
40 - fix unintended xthread_create by intentionalising it :)
41
424.17 Thu Oct 11 05:19:47 CEST 2012
43 - rename aio_fallocate to aio_allocate, to match documentation.
44 - add list of linux fsid values to aio_statvfs docs.
45 - work around a bug in btrfs' FIEMAP ioctl implementation.
46 - work around AIX bug: statvfs.f_fsid is a struct, not unsigned long
47 as per unix spec.
48
494.16 Tue Aug 14 05:39:03 CEST 2012
50 - aio_statvfs was wromgly marked for wd emulation, causing
51 it to malfunction for paths.
52 - fix a crash in aio_fiemap, when used on ranges without any
53 extents.
54 - work around linux kernel bug (at least in 3.2): kernel might
55 trash fiemap input arguments.
56 - work around linux kernel bug (at least in 3.2): kernel does not
57 set FIEMAP_EXTENT_LAST on last segment.
58 - work around linux kernel bug (at least in 3.2): kernel silently
59 truncates segment count if a file.
60 - make fh argument of IO::AIO::mmap optional, also add mmap/munmap
61 to quick overview.
62 - splice can corrupt data.
63 - (libeio) remove pread/pwrite emulation.
64 - do not grow mmaped scalars in aio_read.
65 - add FALLOC_FL_PUNCH_HOLE and document fallocate.
66 - provide pread/pwrite for win32, making it link again on native win32.
67
684.15 Tue Apr 10 06:59:00 CEST 2012
69 - always include linux/types.h for fiemap, for compatibility to
70 ancient systems (Paul Howarth).
71 - experimental support for IO::AIO::splice and ::tee (no aio_...).
72 - provide SEEK_HOLE and SEEK_DATA, if available.
73 - work around (again!) an immensely stupid bug in RHEL, defining
74 autoconf macros in linux system headers (analysed by Paul Howarth).
75
764.14 Sat Apr 7 02:45:18 CEST 2012
77 - fix stat structure usage on windows, which caused bogus stat results.
78 - (libeio) make readahead emulation behave more like actual readahead by never failing.
79 - new request aio_seek.
80 - new request aio_fiemap.
81 - autogenerate the #ifdef/#define 0 blocks for symbols we export.
82
834.12 Fri Dec 30 08:51:25 CET 2011
84 - realpath would return a random value if the name was too long,
85 instead of -1.
86 - port to c89.
87
884.11 Mon Oct 10 00:24:11 CEST 2011
89 - libeio didn't compile on !linux (Paul Howarth).
90
914.1 Sun Oct 9 10:24:11 CEST 2011
92 - IO::AIO did access uninitialised memory on unsuccessful stats.
93 - (libeio) added syncfs syscall wrapper.
94 - (libeio) set thread name on linux (ps -L/Hcx, top, gdb).
95 - (libeio) support multiple indepenent working directories.
96 - applied speling corrections by Nicholas Bamber.
97 - tune treescan #threads and #outstanding requests a bit.
98 - reduce the number of file descriptors in use at any one time
99 in treescan, to avoid running out of them (and using too much ram).
100 - take advantage of working directoriy abstractions
101 in aio_scandir and treescan.
102 - reduce compiled size by ~10% by not inlining some key functionality.
103 - added --progress switch to treescan.
104
1054.0 Mon Jul 18 05:01:10 CEST 2011
106 - INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
107 see FORK BEHAVIOUR in manpage for details.
108 - passes testsuite on win32 now and may actually work
109 (activestate 5.10.1 / MSVC6, YMMV).
110 - (libeio) fix a deadlock where a wakeup signal could be missed when
111 a timeout occured at the same time.
112 - (libeio) added realpath.
113 - (libeio) added fallocate.
114 - (libeio) disabling sendfile on darwin unfortunately broke the emulation.
115 - (libeio) do not acquire any locks when forking.
116 - (libeio) use fewer time() syscalls when waiting for new requests.
117
1183.93 Wed Jun 29 23:44:18 CEST 2011
119 - ECB.H WAS MISSING.
120
1213.92 Wed Jun 29 14:45:41 CEST 2011
122 - ecb.h was missing.
123
1243.91 Wed Jun 29 13:24:42 CEST 2011
125 - (libeio) work around a Linux (and likely FreeBSD and other
126 kernels) bug where sendfile would not transfer all the requested
127 bytes on large transfers, using a heuristic.
128 - buggy sendfile caused aio_move/copy to sometimes fail for big
129 files (fortunately it checks that the whole file has been
130 transferred...)
131 - use libecb for higher performance and higher portability.
132 - (libeio) disable sendfile on darwin, it's too broken.
133 - disable fork tests on !linux, as only linux supports mixing
134 pthread and fork in perl.
135 - document the fact that fork doesn't work anymore when using
136 this module, on anything !GNU/Linux.
137 - increase timeout in t/04_fork.t, as too many CPAN-tester setups
138 run on a 0.1MHz cpu. Or so.
139
1403.9 Fri May 27 02:43:47 CEST 2011
141 - (libeio) fix memory corruption in aio_readdirx for the flags
142 combination READDIR_STAT_ORDER | READDIR_DIRS_FIRST.
143 - add lots of newer POSIX and GNU/Linux-specific open
144 flags.
145
1463.8 Sun Mar 27 12:25:33 CEST 2011
147 - use nonstandard but maybe-working-on-bsd fork technique.
148 - support a max_idle value of 0.
149 - support setting of idle timeout value (IO::AIO::idle_timeout).
150
1513.72 Fri Feb 11 04:25:38 CET 2011
152 - use _POSIX_MEMLOCK_RANGE to detect mlock/munlock.
153 - aio_mknod always used a dev_t value of 0.
154 - new treescan option: --grep.
155 - add more S_IF macros, and major/minor/makedev "macros".
156
1573.71 Thu Dec 30 08:18:46 CET 2010
158 - the numerical result value passed to callbacks did not stringify
159 correctly, due to internal reuse and failure to reset the sv flags.
160 - actually test for posix_[mf]advise, as at least uClibc defines
161 _POSIX_ADVISORY_INFO without actually having any of the required
162 funcitonality. ugh.
163
1643.7 Mon Nov 1 23:00:34 CET 2010
165 - implement/add madvise, mmap, munmap, aio_mlockall, munlockall,
166 aio_mlock, munlock, msync and mtouch to @EXPORT_OK.
167 - document the sad state of affairs w.r.t. pthread on many bsds.
168 - do not enable mmap on systems without _POSIX_MAPPED_FILES
169 (openbsd 4.8).
170 - do not leak memory in IO::AIO::mmap when the scalar already
171 had string-data.
172 - add O_RDWR, O_APPEND and O_EXCL symbols and semi-document
173 them.
174 - cache the result IV, for a minor speedup in the common case.
175 - croak when an mmapped-scalar changes location, to detect
176 user-errors better.
177 - fix aio_readlink prototype.
178
1793.65 Wed Mar 31 02:45:05 CEST 2010
180 - actually use PATH_MAX instead of NAME_MAX for readlink, as to not
181 cut off long pathnames in aio_readlink (based on patch by
182 Rasmus Andersson).
183 - a double fork partially killed the event pipe (great testcase
184 by dormando). affects IO::AIO, BDB and Async::Interrupt.
185 - suck steve's dick and rename our symbols to avoid colliding
186 with nonstandard identifier spam on the broken os x pseudo-os.
187 affects IO::AIO and BDB.
188
1893.6 Mon Jan 11 00:43:39 CET 2010
11 - (libeio) more fixes for the freebsd/apple sendfile - broken by 190 - (libeio) more fixes for the freebsd/apple sendfile - broken by
12 manpage standards, but apparently correct accoridng to actual 191 manpage standards, but apparently correct accoridng to actual
13 kernel sources. 192 kernel sources.
193 - add IO::AIO::mmap/munmap support.
194 - add IO::AIO::m(un)lockall support.
195 - clean up manpage.

16 - (liebio) fix freebsd sendfile (Vanilla Hsu). 198 - (liebio) fix freebsd sendfile (Vanilla Hsu).
17 - (libeio) also fix darwin sendfile that suffered from a similar bug. 199 - (libeio) also fix darwin sendfile that suffered from a similar bug.
18 - add aio_statvfs as interface to statvfs/fstatvfs. 200 - add aio_statvfs as interface to statvfs/fstatvfs.
