7 | |
|
|
8 | - fix a bug in aio_move where it would fail everytime |
|
|
9 | it would have to copy files manually. |
|
|
10 | - start threads only on (very low) demand. |
|
|
11 | - some tuning applied to random places. |
|
|
12 | - add aio_mknod. |
|
|
13 | |
|
|
14 | 2.0 Thu Oct 26 18:27:58 CEST 2006 |
|
|
15 | - minor incompatibility: max_outstanding semantics have changed. |
|
|
16 | - major rewrite, consider all functionality EXPERIMENTAL. |
|
|
17 | - aio requests can be cancelled. |
|
|
18 | - callbacks can be (re-)set later. |
|
|
19 | - aio requests can choose between 9 priorities. |
|
|
20 | - add aio_group: aio requests can be grouped |
|
|
21 | into composite requests. |
|
|
22 | - generator interface for groups. |
|
|
23 | - add IO::AIO::poll_some. |
|
|
24 | - major documentation improvements. |
|
|
25 | - very minor bugfixes. |
|
|
26 | - add aio_nop for dummy requests. |
|
|
27 | - add aio_busy mainly for benchmarking and debugging. |
|
|
28 | - use "fast" mutexes on linux. |
|
|
29 | - use dynamic (and larger) buffers instead of |
|
|
30 | putting them onto the stack. |
|
|
31 | - optimise x86 and amd64 a bit. |
|
|
32 | - better error checking when ENOMEM. |
|
|
33 | - hopefully fix mem and dirp leaks on fork. |
|
|
34 | - warn about broken perl malloc. |
|
|
35 | - compiles on cygwin (but pread is broken on cygwin |
|
|
36 | which is not detected by autoconf, so you have to |
|
|
37 | edit autoconf/config.h yourself to enable emulation). |
|
|
38 | |
|
|
39 | 1.8 Sat Jun 24 22:20:44 CEST 2006 |
|
|
40 | - add and/or document aio_rename, aio_link, aio_symlink and aio_move. |
|
|
41 | |
|
|
42 | 1.73 Wed Mar 1 22:49:32 CET 2006 |
|
|
43 | - codename "jost" |
|
|
44 | - AIX/Solaris(?) aren't being helpful again, hardcode a value |
|
|
45 | for NAME_MAX and drive with your eyes closed (reported by |
|
|
46 | wcooley@nakedape.cc). |
|
|
47 | |
|
|
48 | 1.72 Thu Feb 2 00:40:44 CET 2006 |
|
|
49 | - another minor bug in aio_scandir, again, the callback was called |
|
|
50 | twice when the directory can't be stat'ed. |
|
|
51 | |
|
|
52 | 1.71 Mon Dec 26 20:20:03 CET 2005 |
|
|
53 | - grr, another minor bug in aio_scandir, this time resulting |
|
|
54 | in a runtime error. |
|
|
55 | |
|
|
56 | 1.7 Mon Dec 26 19:29:48 CET 2005 |
|
|
57 | - aio_scandir errornously called callback twice in some cases. |
|
|
58 | - added AnyEvent example. |
|
|
59 | |
|
|
60 | 1.61 Wed Sep 7 19:40:42 CEST 2005 |
|
|
61 | - no longer include $Config{libs}, as distros include too much |
|
|
62 | garbage in there that is not installed on typical systems |
|
|
63 | (for example, debian links perl against -lgdbm and many more |
|
|
64 | libraries despite perl not needing it, slowing down startup and |
|
|
65 | wasting memory). |
|
|
66 | |
|
|
67 | 1.6 Tue Aug 30 17:44:44 CEST 2005 |
|
|
68 | - added aio_readdir, aio_scandir. |
|
|
69 | - added aio_sendfile, including sendfile emulation when sendfile |
|
|
70 | isn't available. Linux, FreeBSD and HP-UX might work (sendfilev |
|
|
71 | support is unavailable on my solaris 8 machine, but preliminary |
|
|
72 | code is there. What's lacking is configury stuff and testing...). |
|
|
73 | |
|
|
74 | 1.5 Sat Aug 20 02:32:19 CEST 2005 |
|
|
75 | - create the aio threads on demand only (good after forking). |
|
|
76 | - somebody nagged about C89 compatibility, so this release should |
|
|
77 | be C89 compatible, but no guarantees for future ones. |
|
|
78 | - abort when the configure script fails. |
|
|
79 | |
|
|
80 | 1.4 Wed Aug 17 08:07:27 CEST 2005 |
|
|
81 | - forgot to recreate the pipe after forking, this could cause |
|
|
82 | deadlocks. |
|
|
83 | |
|
|
84 | 1.3 Wed Aug 17 07:25:54 CEST 2005 |
|
|
85 | - properly propagate exceptions from callbacks, instead of silently |
|
|
86 | eating them. |
|
|
87 | - use a different fork algorithm that avoids recursive callback |
|
|
88 | invocations and reduces fork latency in busy processes. |
|
|
89 | - fix a bug where the buffer scalar in aio_read got assigned the wrong |
|
|
90 | length after reading. |
|
|
91 | - fix a bug where the child would process some outstanding requests |
|
|
92 | from the parent. |
|
|
93 | - make a copy of the callback scalar, to avoid some very uncommon |
|
|
94 | (but valid) usages where the callback scalar changes. |
|
|
95 | - the callback was never freed in aio_read/aio_write. |
|
|
96 | - aio_read/aio_write will now set the readonly flag on the data |
|
|
97 | scalar for better error reporting. |
|
|
98 | |
|
|
99 | 1.2 Wed Aug 17 01:22:58 CEST 2005 |
|
|
100 | - verified on cygwin, linux/amd64+ia32+alpha, solaris. |
|
|
101 | - use SvPVbyte for filenames now. You *need* to encode your strings to |
|
|
102 | the external filename encoding first. |
|
|
103 | - fix the bug where filehandles could leak (again). |
|
|
104 | - clarify freebsd situation: make it work and tell me how, or go away |
|
|
105 | with your underdocumented, broken and outdated OS. |
|
|
106 | - fork'ing should now be officially supported (where linux and |
|
|
107 | posix contradict each other, I followed posix). |
|
|
108 | - only call read() once per poll, not twice (speedup). |
|
|
109 | - new functions: aio_rmdir, aio_symlink. |
|
|
110 | - force callback arguments to be undef or a reference, for better |
|
|
111 | error catching. |
|
|
112 | |
|
|
113 | 1.1 Sun Aug 7 05:27:23 CEST 2005 |
| 4 | - added configure script to detetc availability of some calls. |
114 | - added configure script to detect availability of some calls. |
|
|
115 | (imperfect, as we cannot detect things like -lrt due to missing |
|
|
116 | feedback yet). |
| 5 | - emulate fdatasync by fsync, pread/pwrite by unsafe read/write |
117 | - emulate fdatasync via fsync, pread/pwrite via unsafe read/write |
| 6 | and readahead by manual reading on platforms lacking those. |
118 | and readahead via manual reading on platforms lacking those. |
| 7 | - ported t/03_errors.t+framework by Brad Fitzpatrick |
119 | - ported t/03_errors.t+framework by Brad Fitzpatrick |
| 8 | from Linux::AIO. |
120 | from Linux::AIO. |
| 9 | - removed XOPEN_SOURCE because stupid solaris 9 doesn't |
121 | - removed XOPEN_SOURCE because stupid solaris 9 doesn't |
| 10 | compile with it enabled. Probably breaks others. Oh well. |
122 | compile with it enabled. Probably breaks others. Oh well. |
|
|
123 | - try to be more careful with errno on non-threaded perls. |
|
|
124 | - cygwins perl insisted on a matching open mode when morphing |
|
|
125 | the fd to an fh. |
|
|
126 | - convert sv's to "byte" encoding in aio_read/aio_write. Might |
|
|
127 | do that for pathnames, too, in the future, so make sure you |
|
|
128 | properly encode your pathnames. |
