10 12
13 - make fh argument of IO::AIO::mmap optional, also add mmap/munmap
14 to quick overview.
15 - splice can corrupt data.
16 - (libeio) remove pread/pwrite emulation.
17 - do not grow mmaped scalars in aio_read.
18 - add FALLOC_FL_PUNCH_HOLE.
19
204.15 Tue Apr 10 06:59:00 CEST 2012
21 - always include linux/types.h for fiemap, for compatibility to
22 ancient systems (Paul Howarth).
23 - experimental support for IO::AIO::splice and ::tee (no aio_...).
24 - provide SEEK_HOLE and SEEK_DATA, if available.
25 - work around (again!) an immensely stupid bug in RHEL, defining
26 autoconf macros in linux system headers (analysed by Paul Howarth).
27
284.14 Sat Apr 7 02:45:18 CEST 2012
29 - fix stat structure usage on windows, which caused bogus stat results.
30 - (libeio) make readahead emulation behave more like actual readahead by never failing.
31 - new request aio_seek.
32 - new request aio_fiemap.
33 - autogenerate the #ifdef/#define 0 blocks for symbols we export.
34
354.12 Fri Dec 30 08:51:25 CET 2011
36 - realpath would return a random value if the name was too long,
37 instead of -1.
38 - port to c89.
39
404.11 Mon Oct 10 00:24:11 CEST 2011
41 - libeio didn't compile on !linux (Paul Howarth).
42
434.1 Sun Oct 9 10:24:11 CEST 2011
44 - IO::AIO did access uninitialised memory on unsuccessful stats.
45 - (libeio) added syncfs syscall wrapper.
46 - (libeio) set thread name on linux (ps -L/Hcx, top, gdb).
47 - (libeio) support multiple indepenent working directories.
48 - applied speling corrections by Nicholas Bamber.
49 - tune treescan #threads and #outstanding requests a bit.
50 - reduce the number of file descriptors in use at any one time
51 in treescan, to avoid running out of them (and using too much ram).
52 - take advantage of working directoriy abstractions
53 in aio_scandir and treescan.
54 - reduce compiled size by ~10% by not inlining some key functionality.
55 - added --progress switch to treescan.
56
574.0 Mon Jul 18 05:01:10 CEST 2011
58 - INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
59 see FORK BEHAVIOUR in manpage for details.
60 - passes testsuite on win32 now and may actually work
61 (activestate 5.10.1 / MSVC6, YMMV).
62 - (libeio) fix a deadlock where a wakeup signal could be missed when
63 a timeout occured at the same time.
64 - (libeio) added realpath.
65 - (libeio) added fallocate.
66 - (libeio) disabling sendfile on darwin unfortunately broke the emulation.
67 - (libeio) do not acquire any locks when forking.
68 - (libeio) use fewer time() syscalls when waiting for new requests.
69
703.93 Wed Jun 29 23:44:18 CEST 2011
71 - ECB.H WAS MISSING.
72
733.92 Wed Jun 29 14:45:41 CEST 2011
74 - ecb.h was missing.
75
763.91 Wed Jun 29 13:24:42 CEST 2011
77 - (libeio) work around a Linux (and likely FreeBSD and other
78 kernels) bug where sendfile would not transfer all the requested
79 bytes on large transfers, using a heuristic.
80 - buggy sendfile caused aio_move/copy to sometimes fail for big
81 files (fortunately it checks that the whole file has been
82 transferred...)
83 - use libecb for higher performance and higher portability.
84 - (libeio) disable sendfile on darwin, it's too broken.
85 - disable fork tests on !linux, as only linux supports mixing
86 pthread and fork in perl.
87 - document the fact that fork doesn't work anymore when using
88 this module, on anything !GNU/Linux.
89 - increase timeout in t/04_fork.t, as too many CPAN-tester setups
90 run on a 0.1MHz cpu. Or so.
91
923.9 Fri May 27 02:43:47 CEST 2011
93 - (libeio) fix memory corruption in aio_readdirx for the flags
94 combination READDIR_STAT_ORDER | READDIR_DIRS_FIRST.
95 - add lots of newer POSIX and GNU/Linux-specific open
96 flags.
97
983.8 Sun Mar 27 12:25:33 CEST 2011
99 - use nonstandard but maybe-working-on-bsd fork technique.
100 - support a max_idle value of 0.
101 - support setting of idle timeout value (IO::AIO::idle_timeout).
102
1033.72 Fri Feb 11 04:25:38 CET 2011
104 - use _POSIX_MEMLOCK_RANGE to detect mlock/munlock.
105 - aio_mknod always used a dev_t value of 0.
106 - new treescan option: --grep.
107 - add more S_IF macros, and major/minor/makedev "macros".
108
1093.71 Thu Dec 30 08:18:46 CET 2010
110 - the numerical result value passed to callbacks did not stringify
111 correctly, due to internal reuse and failure to reset the sv flags.
112 - actually test for posix_[mf]advise, as at least uClibc defines
113 _POSIX_ADVISORY_INFO without actually having any of the required
114 funcitonality. ugh.
115
1163.7 Mon Nov 1 23:00:34 CET 2010
117 - implement/add madvise, mmap, munmap, aio_mlockall, munlockall,
118 aio_mlock, munlock, msync and mtouch to @EXPORT_OK.
119 - document the sad state of affairs w.r.t. pthread on many bsds.
120 - do not enable mmap on systems without _POSIX_MAPPED_FILES
121 (openbsd 4.8).
122 - do not leak memory in IO::AIO::mmap when the scalar already
123 had string-data.
124 - add O_RDWR, O_APPEND and O_EXCL symbols and semi-document
125 them.
126 - cache the result IV, for a minor speedup in the common case.
127 - croak when an mmapped-scalar changes location, to detect
128 user-errors better.
129 - fix aio_readlink prototype.
130
1313.65 Wed Mar 31 02:45:05 CEST 2010
132 - actually use PATH_MAX instead of NAME_MAX for readlink, as to not
133 cut off long pathnames in aio_readlink (based on patch by
134 Rasmus Andersson).
135 - a double fork partially killed the event pipe (great testcase
136 by dormando). affects IO::AIO, BDB and Async::Interrupt.
137 - suck steve's dick and rename our symbols to avoid colliding
138 with nonstandard identifier spam on the broken os x pseudo-os.
139 affects IO::AIO and BDB.
140
1413.6 Mon Jan 11 00:43:39 CET 2010
11 - (libeio) more fixes for the freebsd/apple sendfile - broken by 142 - (libeio) more fixes for the freebsd/apple sendfile - broken by
12 manpage standards, but apparently correct accoridng to actual 143 manpage standards, but apparently correct accoridng to actual
13 kernel sources. 144 kernel sources.
145 - add IO::AIO::mmap/munmap support.
146 - add IO::AIO::m(un)lockall support.
147 - clean up manpage.

153.5 Thu Jan 7 21:25:04 CET 2010 1493.5 Thu Jan 7 21:25:04 CET 2010
16 - (liebio) fix freebsd sendfile (Vanilla Hsu). 150 - (liebio) fix freebsd sendfile (Vanilla Hsu).
17 - (libeio) also fix darwin sendfile that suffered from a similar bug. 151 - (libeio) also fix darwin sendfile that suffered from a similar bug.
18 - add aio_statvfs as interface to statvfs/fstatvfs. 152 - add aio_statvfs as interface to statvfs/fstatvfs.
