9 | 3.03 |
|
|
10 | - (libeio) correctly call pthread_attr_destroy (). |
|
|
11 | - (libeio) work around broken bsd headers once more. |
|
|
12 | - reduce shared library size again by not including wrappers. |
|
|
13 | - max_outstanding could cause poll to enter a busy-waiting loop. |
|
|
14 | - document the new IO::AIO::poll_cb result value. |
|
|
15 | |
|
|
16 | 3.02 Mon May 12 02:32:02 CEST 2008 |
|
|
17 | - fix a memory leak on aio_readlink. |
|
|
18 | - bring back working fchmod. |
|
|
19 | - nop and busy now set result to 0. |
|
|
20 | - set errno to ENOMEM when allocation fails. |
|
|
21 | |
|
|
22 | 3.01 Sun May 11 03:07:03 CEST 2008 |
|
|
23 | - (libeio) make it compile on systems without readahead or readdir_r. |
|
|
24 | - (libeio) improve configure check for readahead availability. |
|
|
25 | - do not try to link against -lrt. |
|
|
26 | - use a separate configure script for IO::AIO (not the libeio one). |
|
|
27 | |
|
|
28 | 3.0 Sun May 11 00:57:14 CEST 2008 |
|
|
29 | - added bin/treescan to the distribution. |
|
|
30 | - switched to using libeio. |
|
|
31 | - LOTS OF INCOMPATIBLE CHANGES: |
|
|
32 | - remove signal functionality, it is not worth the effort. |
|
|
33 | - max_outstanding no longer returns the previous number of requests. |
|
|
34 | - poll_cb no longer returns number of requests. |
|
|
35 | |
|
|
36 | 2.62 Sat Apr 26 13:59:33 CEST 2008 |
|
|
37 | - port to solaris perls configured for old posix |
|
|
38 | (analysed by Jost Krieger). |
|
|
39 | - keep a reference to the perl filehandle object in aio_close, |
|
|
40 | so it doesn't get closed prematurely, leading to ugly races. |
|
|
41 | |
|
|
42 | 2.61 Wed Apr 16 18:45:02 CEST 2008 |
|
|
43 | - fix treescan output duplication and improve output ordering. |
|
|
44 | also display files given on the commandline. |
|
|
45 | - use a different algorithm for aio_close that is faster |
|
|
46 | and probably has even lower chances of blocking. |
|
|
47 | - do our own stack memory management for threads - linux |
|
|
48 | allocates outrageous amounts of VM (not so bad unless you |
|
|
49 | use mlockall...), which severely limits the number of threads |
|
|
50 | on 32-bit arches: stack size is the larger of PTHREAD_STACK_MIN |
|
|
51 | and 4096 * sizeof (long) (usually this is 16..64k). |
|
|
52 | |
|
|
53 | 2.6 Sun Mar 30 08:28:11 CEST 2008 |
|
|
54 | - added aio_sync. |
|
|
55 | - added aio_pathsync. |
|
|
56 | - fix prototypes of (void) functions. |
|
|
57 | |
|
|
58 | 2.51 Sat Oct 6 16:04:54 CEST 2007 |
|
|
59 | - perlio isn't generally threadsafe, so aio_close could not work reliably. |
|
|
60 | aio_close now tries a safe hack that might not be that asynchronous |
|
|
61 | (see the manpage for details). |
|
|
62 | - discard callback return values as to not grow the stack endlessly |
|
|
63 | when poll_cb handles many requests without returning. |
|
|
64 | - minor code cleanups. |
|
|
65 | |
|
|
66 | 2.5 Thu Oct 4 14:49:08 CEST 2007 |
|
|
67 | - replaced _fd2fh with faster xs code. |
|
|
68 | - aio_close will now try to do "the right thing" and thus might |
|
|
69 | work sensibly for the very first time. |
|
|
70 | |
|
|
71 | 2.41 Mon Sep 24 21:28:21 CEST 2007 |
|
|
72 | - after fork, invest some work to make sure that the poll_fileno |
|
|
73 | stays stable (by dup2'ing the new fd over the old one), to make |
|
|
74 | it easier for programs/libs that don't control their forking |
|
|
75 | behaviour and cannot recreate their watchers. |
|
|
76 | |
|
|
77 | 2.4 Sun Aug 5 18:44:22 CEST 2007 |
|
|
78 | - add aio_truncate, aio_chmod, aio_chown, aio_utime (linux |
|
|
79 | successfully demonstrated that you can block on futimes...). |
|
|
80 | - allow undef as fileoffset for aio_read/write and use read/write(2) |
|
|
81 | internally (useful for sockets or O_APPEND handles). |
|
|
82 | - allow undef for length in aio_write. |
|
|
83 | - negative dataoffsets work as expected now in aio_read/aio_write. |
|
|
84 | - use NV instead of UV for 32 bit perls and file offsets, as NVs |
|
|
85 | have a larger range then. |
|
|
86 | - shared code between BDB and IO::AIO. |
|
|
87 | - aio_busy was completely broken. now fixed. |
|
|
88 | - readahead emulation now returns something. |
|
|
89 | - correctly set errno to ENOSYS on unimplemented functions |
|
|
90 | (should never happen, though). |
|
|
91 | - large changes to make it partially compile and run on win32, |
|
|
92 | but win32 lacks too much functionality, and perl overrides way |
|
|
93 | too many functions with crashing versions. |
|
|
94 | |
|
|
95 | 2.33 Tue Jan 23 23:55:41 CET 2007 |
|
|
96 | - fix install path (Andreas J. Koenig). |
|
|
97 | |
|
|
98 | 2.32 Mon Jan 22 16:56:23 CET 2007 |
|
|
99 | - added aio_rmtree. |
|
|
100 | - wow, aio_mkdir was missing. |
|
|
101 | - aio_load did return undef on error, not -1. |
|
|
102 | - use prefixexp not prefix in autoconf.pm |
|
|
103 | (suggested by ... rt.cpan.org unreachable). |
|
|
104 | - avoid installing autoconf.pm. |
|
|
105 | |
|
|
106 | 2.31 Sat Jan 6 03:46:02 CET 2007 |
|
|
107 | - added aio_load. |
|
|
108 | |
|
|
109 | 2.3 Sat Dec 23 05:48:07 CET 2006 |
|
|
110 | - fix off-by-one bug in aio_read, causing memory corruption |
|
|
111 | or crashes. |
|
|
112 | |
|
|
113 | 2.21 Fri Dec 22 05:03:38 CET 2006 |
|
|
114 | - minor doc updates. |
|
|
115 | - minor cleanups. |
|
|
116 | - IO::AIO::poll returns request count. |
|
|
117 | - undocumented and unfinished async-signal-reporting. |
|
|
118 | |
|
|
119 | 2.2 Tue Oct 31 00:31:00 CET 2006 |
|
|
120 | - minor doc updates. |
|
|
121 | - added aio_readlink. |
|
|
122 | - properly zero-terminate aio_read buffer. |
|
|
123 | - fix aio_read/write with nonzero dataoffset. |
|
|
124 | - reduced size of aio request structure. |
|
|
125 | - better diagnostics when pathnames etc. are not byte-encoded; |
|
|
126 | do not leak request in that case, either. |
| 6 | |
127 | |
| 7 | 2.1 Sun Oct 29 02:01:57 CET 2006 |
128 | 2.1 Sun Oct 29 02:01:57 CET 2006 |
| 8 | - INCOMPATIBLE CHANGE: replace IO::AIO::poll_some by |
129 | - INCOMPATIBLE CHANGE: replace IO::AIO::poll_some by |
| 9 | IO::AIO::max_poll_reqs and IO::AIO::max_poll_time. |
130 | IO::AIO::max_poll_reqs and IO::AIO::max_poll_time. |
| 10 | - fix a bug in aio_move where it would fail everytime |
