13 | 4.18 Thu Oct 11 07:01:26 CEST 2012 |
|
|
14 | - fix unintended xthread_create by intentionalising it :) |
|
|
15 | |
|
|
16 | 4.17 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 | |
|
|
23 | 4.16 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 | |
|
|
42 | 4.15 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 | |
|
|
50 | 4.14 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 | |
|
|
57 | 4.12 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 | |
|
|
62 | 4.11 Mon Oct 10 00:24:11 CEST 2011 |
|
|
63 | - libeio didn't compile on !linux (Paul Howarth). |
|
|
64 | |
|
|
65 | 4.1 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 | |
|
|
79 | 4.0 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 | |
|
|
92 | 3.93 Wed Jun 29 23:44:18 CEST 2011 |
|
|
93 | - ECB.H WAS MISSING. |
|
|
94 | |
|
|
95 | 3.92 Wed Jun 29 14:45:41 CEST 2011 |
|
|
96 | - ecb.h was missing. |
|
|
97 | |
|
|
98 | 3.91 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 | |
|
|
114 | 3.9 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 | |
|
|
120 | 3.8 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 | |
|
|
125 | 3.72 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". |
| 12 | |
130 | |
| 13 | 3.71 Thu Dec 30 08:18:46 CET 2010 |
131 | 3.71 Thu Dec 30 08:18:46 CET 2010 |
| 14 | - the numerical result value passed to callbacks did not stringify |
132 | - the numerical result value passed to callbacks did not stringify |
| 15 | correctly, due to internal reuse and failure to reset the sv flags. |
133 | correctly, due to internal reuse and failure to reset the sv flags. |
| 16 | - actually test for posix_[mf]advise, as at least uClibc defines |
134 | - actually test for posix_[mf]advise, as at least uClibc defines |
