|
|
9 | - work around perl overriding readdir etc. with thread-unsafe |
|
|
10 | versions (omg). |

|
|
12 | 3.04 Wed Jun 18 01:35:38 CEST 2008 |
|
|
13 | - (libeio) fix eio_mknod, which confused it's arguments. |
|
|
14 | - (libeio) do not use readdir_r, as Ulrich Drepper pointed out that this |
|
|
15 | is stupid. |
|
|
16 | - (libeio) fix eio__readahead prototype, patch by Jost Krieger. |
|
|
17 | - (libeio) fix a bug that could potentially cause IO::AIO |
|
|
18 | not to get initialised properly. |
|
|
19 | |
|
|
20 | 3.03 Thu May 29 05:33:30 CEST 2008 |
|
|
21 | - (libeio) correctly call pthread_attr_destroy (). |
|
|
22 | - (libeio) work around broken bsd headers once more. |
|
|
23 | - reduce shared library size again by not including wrappers. |
|
|
24 | - max_outstanding could cause poll to enter a busy-waiting loop. |
|
|
25 | - document the new IO::AIO::poll_cb result value. |
|
|
26 | |
|
|
27 | 3.02 Mon May 12 02:32:02 CEST 2008 |
|
|
28 | - fix a memory leak on aio_readlink. |
|
|
29 | - bring back working fchmod. |
|
|
30 | - nop and busy now set result to 0. |
|
|
31 | - set errno to ENOMEM when allocation fails. |
|
|
32 | |
|
|
33 | 3.01 Sun May 11 03:07:03 CEST 2008 |
|
|
34 | - (libeio) make it compile on systems without readahead or readdir_r. |
|
|
35 | - (libeio) improve configure check for readahead availability. |
|
|
36 | - do not try to link against -lrt. |
|
|
37 | - use a separate configure script for IO::AIO (not the libeio one). |
|
|
38 | |
|
|
39 | 3.0 Sun May 11 00:57:14 CEST 2008 |
|
|
40 | - added bin/treescan to the distribution. |
|
|
41 | - switched to using libeio. |
|
|
42 | - LOTS OF INCOMPATIBLE CHANGES: |
|
|
43 | - remove signal functionality, it is not worth the effort. |
|
|
44 | - max_outstanding no longer returns the previous number of requests. |
|
|
45 | - poll_cb no longer returns number of requests. |
|
|
46 | |
|
|
47 | 2.62 Sat Apr 26 13:59:33 CEST 2008 |
|
|
48 | - port to solaris perls configured for old posix |
|
|
49 | (analysed by Jost Krieger). |
|
|
50 | - keep a reference to the perl filehandle object in aio_close, |
|
|
51 | so it doesn't get closed prematurely, leading to ugly races. |
|
|
52 | |
|
|
53 | 2.61 Wed Apr 16 18:45:02 CEST 2008 |
|
|
54 | - fix treescan output duplication and improve output ordering. |
|
|
55 | also display files given on the commandline. |
|
|
56 | - use a different algorithm for aio_close that is faster |
|
|
57 | and probably has even lower chances of blocking. |
|
|
58 | - do our own stack memory management for threads - linux |
|
|
59 | allocates outrageous amounts of VM (not so bad unless you |
|
|
60 | use mlockall...), which severely limits the number of threads |
|
|
61 | on 32-bit arches: stack size is the larger of PTHREAD_STACK_MIN |
|
|
62 | and 4096 * sizeof (long) (usually this is 16..64k). |
|
|
63 | |
|
|
64 | 2.6 Sun Mar 30 08:28:11 CEST 2008 |
|
|
65 | - added aio_sync. |
|
|
66 | - added aio_pathsync. |
|
|
67 | - fix prototypes of (void) functions. |
|
|
68 | |
|
|
69 | 2.51 Sat Oct 6 16:04:54 CEST 2007 |
|
|
70 | - perlio isn't generally threadsafe, so aio_close could not work reliably. |
|
|
71 | aio_close now tries a safe hack that might not be that asynchronous |
|
|
72 | (see the manpage for details). |
|
|
73 | - discard callback return values as to not grow the stack endlessly |
|
|
74 | when poll_cb handles many requests without returning. |
|
|
75 | - minor code cleanups. |
|
|
76 | |
|
|
77 | 2.5 Thu Oct 4 14:49:08 CEST 2007 |
|
|
78 | - replaced _fd2fh with faster xs code. |
|
|
79 | - aio_close will now try to do "the right thing" and thus might |
|
|
80 | work sensibly for the very first time. |
|
|
81 | |
|
|
82 | 2.41 Mon Sep 24 21:28:21 CEST 2007 |
|
|
83 | - after fork, invest some work to make sure that the poll_fileno |
|
|
84 | stays stable (by dup2'ing the new fd over the old one), to make |
|
|
85 | it easier for programs/libs that don't control their forking |
|
|
86 | behaviour and cannot recreate their watchers. |
|
|
87 | |
|
|
88 | 2.4 Sun Aug 5 18:44:22 CEST 2007 |
|
|
89 | - add aio_truncate, aio_chmod, aio_chown, aio_utime (linux |
|
|
90 | successfully demonstrated that you can block on futimes...). |
|
|
91 | - allow undef as fileoffset for aio_read/write and use read/write(2) |
|
|
92 | internally (useful for sockets or O_APPEND handles). |
|
|
93 | - allow undef for length in aio_write. |
|
|
94 | - negative dataoffsets work as expected now in aio_read/aio_write. |
|
|
95 | - use NV instead of UV for 32 bit perls and file offsets, as NVs |
|
|
96 | have a larger range then. |
|
|
97 | - shared code between BDB and IO::AIO. |
|
|
98 | - aio_busy was completely broken. now fixed. |
|
|
99 | - readahead emulation now returns something. |
|
|
100 | - correctly set errno to ENOSYS on unimplemented functions |
|
|
101 | (should never happen, though). |
|
|
102 | - large changes to make it partially compile and run on win32, |
|
|
103 | but win32 lacks too much functionality, and perl overrides way |
|
|
104 | too many functions with crashing versions. |

106 | 2.33 Tue Jan 23 23:55:41 CET 2007 |
