134.18 Thu Oct 11 07:01:26 CEST 2012
14 - fix unintended xthread_create by intentionalising it :)
15
164.17 Thu Oct 11 05:19:47 CEST 2012
17 - rename aio_fallocate to aio_allocate, to match documentation.
18 - add list of linux fsid values to aio_statvfs docs.
19 - work around a bug in btrfs' FIEMAP ioctl implementation.
20 - work around AIX bug: statvfs.f_fsid is a struct, not unsigned long
21 as per unix spec.
22
234.16 Tue Aug 14 05:39:03 CEST 2012
24 - aio_statvfs was wromgly marked for wd emulation, causing
25 it to malfunction for paths.
26 - fix a crash in aio_fiemap, when used on ranges without any
27 extents.
28 - work around linux kernel bug (at least in 3.2): kernel might
29 trash fiemap input arguments.
30 - work around linux kernel bug (at least in 3.2): kernel does not
31 set FIEMAP_EXTENT_LAST on last segment.
32 - work around linux kernel bug (at least in 3.2): kernel silently
33 truncates segment count if a file.
34 - make fh argument of IO::AIO::mmap optional, also add mmap/munmap
35 to quick overview.
36 - splice can corrupt data.
37 - (libeio) remove pread/pwrite emulation.
38 - do not grow mmaped scalars in aio_read.
39 - add FALLOC_FL_PUNCH_HOLE and document fallocate.
40 - provide pread/pwrite for win32, making it link again on native win32.
41
424.15 Tue Apr 10 06:59:00 CEST 2012
43 - always include linux/types.h for fiemap, for compatibility to
44 ancient systems (Paul Howarth).
45 - experimental support for IO::AIO::splice and ::tee (no aio_...).
46 - provide SEEK_HOLE and SEEK_DATA, if available.
47 - work around (again!) an immensely stupid bug in RHEL, defining
48 autoconf macros in linux system headers (analysed by Paul Howarth).
49
504.14 Sat Apr 7 02:45:18 CEST 2012
51 - fix stat structure usage on windows, which caused bogus stat results.
52 - (libeio) make readahead emulation behave more like actual readahead by never failing.
53 - new request aio_seek.
54 - new request aio_fiemap.
55 - autogenerate the #ifdef/#define 0 blocks for symbols we export.
56
574.12 Fri Dec 30 08:51:25 CET 2011
58 - realpath would return a random value if the name was too long,
59 instead of -1.
60 - port to c89.
61
624.11 Mon Oct 10 00:24:11 CEST 2011
63 - libeio didn't compile on !linux (Paul Howarth).
64
654.1 Sun Oct 9 10:24:11 CEST 2011
66 - IO::AIO did access uninitialised memory on unsuccessful stats.
67 - (libeio) added syncfs syscall wrapper.
68 - (libeio) set thread name on linux (ps -L/Hcx, top, gdb).
69 - (libeio) support multiple indepenent working directories.
70 - applied speling corrections by Nicholas Bamber.
71 - tune treescan #threads and #outstanding requests a bit.
72 - reduce the number of file descriptors in use at any one time
73 in treescan, to avoid running out of them (and using too much ram).
74 - take advantage of working directoriy abstractions
75 in aio_scandir and treescan.
76 - reduce compiled size by ~10% by not inlining some key functionality.
77 - added --progress switch to treescan.
78
794.0 Mon Jul 18 05:01:10 CEST 2011
80 - INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
81 see FORK BEHAVIOUR in manpage for details.
82 - passes testsuite on win32 now and may actually work
83 (activestate 5.10.1 / MSVC6, YMMV).
84 - (libeio) fix a deadlock where a wakeup signal could be missed when
85 a timeout occured at the same time.
86 - (libeio) added realpath.
87 - (libeio) added fallocate.
88 - (libeio) disabling sendfile on darwin unfortunately broke the emulation.
89 - (libeio) do not acquire any locks when forking.
90 - (libeio) use fewer time() syscalls when waiting for new requests.
91
923.93 Wed Jun 29 23:44:18 CEST 2011
93 - ECB.H WAS MISSING.
94
953.92 Wed Jun 29 14:45:41 CEST 2011
96 - ecb.h was missing.
97
983.91 Wed Jun 29 13:24:42 CEST 2011
99 - (libeio) work around a Linux (and likely FreeBSD and other
100 kernels) bug where sendfile would not transfer all the requested
101 bytes on large transfers, using a heuristic.
102 - buggy sendfile caused aio_move/copy to sometimes fail for big
103 files (fortunately it checks that the whole file has been
104 transferred...)
105 - use libecb for higher performance and higher portability.
106 - (libeio) disable sendfile on darwin, it's too broken.
107 - disable fork tests on !linux, as only linux supports mixing
108 pthread and fork in perl.
109 - document the fact that fork doesn't work anymore when using
110 this module, on anything !GNU/Linux.
111 - increase timeout in t/04_fork.t, as too many CPAN-tester setups
112 run on a 0.1MHz cpu. Or so.
113
1143.9 Fri May 27 02:43:47 CEST 2011
115 - (libeio) fix memory corruption in aio_readdirx for the flags
116 combination READDIR_STAT_ORDER | READDIR_DIRS_FIRST.
117 - add lots of newer POSIX and GNU/Linux-specific open
118 flags.
119
1203.8 Sun Mar 27 12:25:33 CEST 2011
121 - use nonstandard but maybe-working-on-bsd fork technique.
122 - support a max_idle value of 0.
123 - support setting of idle timeout value (IO::AIO::idle_timeout).
124
1253.72 Fri Feb 11 04:25:38 CET 2011
126 - use _POSIX_MEMLOCK_RANGE to detect mlock/munlock.
127 - aio_mknod always used a dev_t value of 0.
128 - new treescan option: --grep.
129 - add more S_IF macros, and major/minor/makedev "macros".
130
1313.71 Thu Dec 30 08:18:46 CET 2010
132 - the numerical result value passed to callbacks did not stringify
133 correctly, due to internal reuse and failure to reset the sv flags.
134 - actually test for posix_[mf]advise, as at least uClibc defines
135 _POSIX_ADVISORY_INFO without actually having any of the required
136 funcitonality. ugh.
137
1383.7 Mon Nov 1 23:00:34 CET 2010
139 - implement/add madvise, mmap, munmap, aio_mlockall, munlockall,
140 aio_mlock, munlock, msync and mtouch to @EXPORT_OK.
141 - document the sad state of affairs w.r.t. pthread on many bsds.
142 - do not enable mmap on systems without _POSIX_MAPPED_FILES
143 (openbsd 4.8).
144 - do not leak memory in IO::AIO::mmap when the scalar already
145 had string-data.
146 - add O_RDWR, O_APPEND and O_EXCL symbols and semi-document
147 them.
148 - cache the result IV, for a minor speedup in the common case.
149 - croak when an mmapped-scalar changes location, to detect
150 user-errors better.
151 - fix aio_readlink prototype.
152
1533.65 Wed Mar 31 02:45:05 CEST 2010
154 - actually use PATH_MAX instead of NAME_MAX for readlink, as to not
155 cut off long pathnames in aio_readlink (based on patch by
156 Rasmus Andersson).
157 - a double fork partially killed the event pipe (great testcase
158 by dormando). affects IO::AIO, BDB and Async::Interrupt.
159 - suck steve's dick and rename our symbols to avoid colliding
160 with nonstandard identifier spam on the broken os x pseudo-os.
161 affects IO::AIO and BDB.
162
1633.6 Mon Jan 11 00:43:39 CET 2010
11 - (libeio) more fixes for the freebsd/apple sendfile - it should now 164 - (libeio) more fixes for the freebsd/apple sendfile - broken by
12 be correct according to the manpage, but it seems to be broken by 165 manpage standards, but apparently correct accoridng to actual
13 design, failing to account some bytes sometimes. 166 kernel sources.
167 - add IO::AIO::mmap/munmap support.
168 - add IO::AIO::m(un)lockall support.
169 - clean up manpage.
14 170

16 - (liebio) fix freebsd sendfile (Vanilla Hsu). 172 - (liebio) fix freebsd sendfile (Vanilla Hsu).
17 - (libeio) also fix darwin sendfile that suffered from a similar bug. 173 - (libeio) also fix darwin sendfile that suffered from a similar bug.
18 - add aio_statvfs as interface to statvfs/fstatvfs. 174 - add aio_statvfs as interface to statvfs/fstatvfs.
