10 | 3.31 Thu Nov 12 02:14:29 CET 2009 |
|
|
11 | - fix result status documentation of aio_copy, aio_move. |
|
|
12 | - speed up object creation considerably by avoiding |
|
|
13 | hash lookups. |
|
|
14 | |
|
|
15 | 3.3 Wed Aug 5 13:52:58 CEST 2009 |
|
|
16 | - use common::sense. |
|
|
17 | - use common schmorp.h header. |
|
|
18 | - allow integers (file descriptors) in addition to file handles. |
|
|
19 | - take advantage of linux' eventfd (but it seems slower on smp?). |
|
|
20 | - use poll not select on posix platforms. |
|
|
21 | |
|
|
22 | 3.261 Wed Jul 1 10:11:51 CEST 2009 |
|
|
23 | - more 0S X workarounds (patch by Tokuhiro Matsuno). |
|
|
24 | |
|
|
25 | 3.26 Tue Jun 30 09:33:26 CEST 2009 |
|
|
26 | - 0S X of course claims to be posix 2008 but lacks posix_fadvise. |
|
|
27 | try to work around this horribly broken OS in a somewhat hackish |
|
|
28 | way. might help other os's too. |
|
|
29 | |
|
|
30 | 3.25 Sat Jun 27 05:18:26 CEST 2009 |
|
|
31 | - added IO::AIO::fadvise and IO::AIO::sendfile. |
|
|
32 | - (libeio) replaced quicksort+insertion sort by a tuned radix |
|
|
33 | sort + insertion sort, resulting in comparable runtime (usually |
|
|
34 | faster) to the old version, but without any ill side effects on |
|
|
35 | degenerated (for quicksort) data. |
|
|
36 | - (libeio) correctly sort dirs by inodes if we have perfect type |
|
|
37 | knowledge and DIRS_FIRST is used. |
|
|
38 | - (libeio) internally the wrong DT_* constants were used, but no |
|
|
39 | known system has differing EIO_DT_*/DT_* values, so not an issue. |
|
|
40 | - removed a (harmless) assert that was left over on the code |
|
|
41 | but should not have been. |
|
|
42 | - use more correct types (change IO length from IV to VAL64, |
|
|
43 | which makes a difference on systems without 64 bit perls). |
|
|
44 | |
|
|
45 | 3.23 Sat Jun 13 16:57:58 CEST 2009 |
|
|
46 | - fix off-by-one bug in aio_readdir that was introduced in the |
|
|
47 | rushed 3.22 release. |
|
|
48 | |
|
|
49 | 3.22 Sat Jun 13 15:32:40 CEST 2009 |
|
|
50 | - speed up readdirx sort algorithm slightly. |
|
|
51 | - bin/treescan was missing from distro tarball. |
|
|
52 | |
|
|
53 | 3.21 Fri Jun 12 18:45:53 CEST 2009 |
|
|
54 | - new options --dirs and --files for treescan. |
|
|
55 | - install bin/treescan by default. |
|
|
56 | - (libeio) aio_readdir can now be cancelled while executing. |
|
|
57 | - fix a printf format string for 64 bit systems (could lead |
|
|
58 | to problems on big endian 64 bit systems). |
|
|
59 | - do not use qsort() but our own algorithm: glibc initialises |
|
|
60 | the whole locale and I/O subsystem inside qsort, causing |
|
|
61 | a stack overflow on 32 bit machines. The new sort uses much less |
|
|
62 | stack and is more than twice as fast in typical situations. |
|
|
63 | |
|
|
64 | 3.2 Sun Jun 7 20:30:05 CEST 2009 |
|
|
65 | - (libeio) pwrite emulation was even more flawed than intended and did |
|
|
66 | not restore the file offset. |
|
|
67 | - add aio_readdirx, which can return inode and filetype and sort |
|
|
68 | the names in various ways. |
|
|
69 | - unfortunately, utime, chmod, chown on an open file that has just |
|
|
70 | been written can easily block, which caused aio_copy to block the |
|
|
71 | process. no more! |
|
|
72 | - no longer rely on dst path in aio_copy when futime is available. |
|
|
73 | |
|
|
74 | 3.19 Tue Apr 21 22:05:21 CEST 2009 |
|
|
75 | - more perl 5.10 workarounds for aio_read and write. |
|
|
76 | - aio_write no longer modifies the sv (if possible). |
|
|
77 | - aio_read now works correctly with magic values. |
|
|
78 | |
|
|
79 | 3.18 Sun Apr 19 21:17:32 CEST 2009 |
|
|
80 | - better diagnostics when some aio_* functions get passed an illegal fh. |
|
|
81 | - try to avoid crashes due to incompatible 5.10 API changes. grmbl. |
|
|
82 | |
|
|
83 | 3.17 Thu Nov 20 08:45:36 CET 2008 |
|
|
84 | - (libeio) added aio_sync_file_range (untested). |
|
|
85 | - add aio_busy to @IO::AIO::AIO_REQ. |
|
|
86 | |
|
|
87 | 3.16 Wed Oct 22 18:28:01 CEST 2008 |
|
|
88 | - use SvREFCNT_inc instead of SvREFCNT_inc_NN in a non-speed critical |
|
|
89 | part to improve portability to perl 5.8 (reported by szymon). |
|
|
90 | |
|
|
91 | 3.15 Mon Oct 13 00:39:55 CEST 2008 |
|
|
92 | - automatic removal of feeders was broken. |
|
|
93 | - (libeio) use a more robust method to detect whether a feeder |
|
|
94 | has added something to the group or not. |
|
|
95 | |
|
|
96 | 3.1 Thu Oct 2 13:34:40 CEST 2008 |
|
|
97 | - pre-deref the passed callback object, for increased speed |
|
|
98 | and decreased memory usage. |
|
|
99 | - call on_next_submit callback even for aio_group - impact unknown, |
|
|
100 | but seems more correct. |
|
|
101 | - $req->cb now returns the original callback. |
|
|
102 | - (libeio) pass EIO_GROUP/aio_group requests through the queue without |
|
|
103 | requiring a thread switch. |
|
|
104 | - (libeio) status code of aio_futime and aio_utime was always passed 0. |
|
|
105 | - do some other ยต-optimisations. |
|
|
106 | |
|
|
107 | 3.07 Sat Aug 2 16:06:13 CEST 2008 |
|
|
108 | - do not include LIBS in autoconf tests. |
|
|
109 | |
|
|
110 | 3.06 Tue Jul 15 12:41:32 CEST 2008 |
|
|
111 | - move preadwritelock definition before it's first reference, |
|
|
112 | to make it compile again on broken platforms (they still exist) |
|
|
113 | or badly cofngiured perls (redhat...), reported by Rob Bloodgood. |
|
|
114 | |
|
|
115 | 3.05 Thu Jun 19 23:23:52 CEST 2008 |
|
|
116 | - work around perl overriding readdir etc. with thread-unsafe |
|
|
117 | (sic!) versions. |
|
|
118 | |
|
|
119 | 3.04 Wed Jun 18 01:35:38 CEST 2008 |
|
|
120 | - (libeio) fix eio_mknod, which confused it's arguments. |
|
|
121 | - (libeio) do not use readdir_r, as Ulrich Drepper pointed out that this |
|
|
122 | is stupid. |
|
|
123 | - (libeio) fix eio__readahead prototype, patch by Jost Krieger. |
|
|
124 | - (libeio) fix a bug that could potentially cause IO::AIO |
|
|
125 | not to get initialised properly. |
|
|
126 | |
|
|
127 | 3.03 Thu May 29 05:33:30 CEST 2008 |
|
|
128 | - (libeio) correctly call pthread_attr_destroy (). |
|
|
129 | - (libeio) work around broken bsd headers once more. |
|
|
130 | - reduce shared library size again by not including wrappers. |
|
|
131 | - max_outstanding could cause poll to enter a busy-waiting loop. |
|
|
132 | - document the new IO::AIO::poll_cb result value. |
|
|
133 | |
|
|
134 | 3.02 Mon May 12 02:32:02 CEST 2008 |
|
|
135 | - fix a memory leak on aio_readlink. |
|
|
136 | - bring back working fchmod. |
|
|
137 | - nop and busy now set result to 0. |
|
|
138 | - set errno to ENOMEM when allocation fails. |
|
|
139 | |
|
|
140 | 3.01 Sun May 11 03:07:03 CEST 2008 |
|
|
141 | - (libeio) make it compile on systems without readahead or readdir_r. |
|
|
142 | - (libeio) improve configure check for readahead availability. |
|
|
143 | - do not try to link against -lrt. |
|
|
144 | - use a separate configure script for IO::AIO (not the libeio one). |
|
|
145 | |
|
|
146 | 3.0 Sun May 11 00:57:14 CEST 2008 |
|
|
147 | - added bin/treescan to the distribution. |
|
|
148 | - switched to using libeio. |
|
|
149 | - LOTS OF INCOMPATIBLE CHANGES: |
|
|
150 | - remove signal functionality, it is not worth the effort. |
|
|
151 | - max_outstanding no longer returns the previous number of requests. |
|
|
152 | - poll_cb no longer returns number of requests. |
|
|
153 | |
|
|
154 | 2.62 Sat Apr 26 13:59:33 CEST 2008 |
|
|
155 | - port to solaris perls configured for old posix |
|
|
156 | (analysed by Jost Krieger). |
|
|
157 | - keep a reference to the perl filehandle object in aio_close, |
|
|
158 | so it doesn't get closed prematurely, leading to ugly races. |
|
|
159 | |
|
|
160 | 2.61 Wed Apr 16 18:45:02 CEST 2008 |
|
|
161 | - fix treescan output duplication and improve output ordering. |
|
|
162 | also display files given on the commandline. |
|
|
163 | - use a different algorithm for aio_close that is faster |
|
|
164 | and probably has even lower chances of blocking. |
|
|
165 | - do our own stack memory management for threads - linux |
|
|
166 | allocates outrageous amounts of VM (not so bad unless you |
|
|
167 | use mlockall...), which severely limits the number of threads |
|
|
168 | on 32-bit arches: stack size is the larger of PTHREAD_STACK_MIN |
|
|
169 | and 4096 * sizeof (long) (usually this is 16..64k). |
|
|
170 | |
|
|
171 | 2.6 Sun Mar 30 08:28:11 CEST 2008 |
| 10 | - added aio_sync. |
172 | - added aio_sync. |
|
|
173 | - added aio_pathsync. |
|
|
174 | - fix prototypes of (void) functions. |
| 11 | |
175 | |
| 12 | 2.51 Sat Oct 6 16:04:54 CEST 2007 |
176 | 2.51 Sat Oct 6 16:04:54 CEST 2007 |
| 13 | - perlio isn't generally threadsafe, so aio_close could not work reliably. |
177 | - perlio isn't generally threadsafe, so aio_close could not work reliably. |
| 14 | aio_close now tries a safe hack that might not be that asynchronous |
