2 2
31.1 3TODO: better autoconf.pm that can return LIBS etc.
4TODO: aio_cp/mvtree/rmtree
5TODO: aio_utime, aio_chmod, aio_chown?
6
7TODO: expose max_idle
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 - end threads automatically after 10s idle.
12 - some tuning applied to random places.
13 - add aio_mknod.
14
152.0 Thu Oct 26 18:27:58 CEST 2006
16 - minor incompatibility: max_outstanding semantics have changed.
17 - major rewrite, consider all functionality EXPERIMENTAL.
18 - aio requests can be cancelled.
19 - callbacks can be (re-)set later.
20 - aio requests can choose between 9 priorities.
21 - add aio_group: aio requests can be grouped
22 into composite requests.
23 - generator interface for groups.
24 - add IO::AIO::poll_some.
25 - major documentation improvements.
26 - very minor bugfixes.
27 - add aio_nop for dummy requests.
28 - add aio_busy mainly for benchmarking and debugging.
29 - use "fast" mutexes on linux.
30 - use dynamic (and larger) buffers instead of
31 putting them onto the stack.
32 - optimise x86 and amd64 a bit.
33 - better error checking when ENOMEM.
34 - hopefully fix mem and dirp leaks on fork.
35 - warn about broken perl malloc.
36 - compiles on cygwin (but pread is broken on cygwin
37 which is not detected by autoconf, so you have to
38 edit autoconf/config.h yourself to enable emulation).
39
401.8 Sat Jun 24 22:20:44 CEST 2006
41 - add and/or document aio_rename, aio_link, aio_symlink and aio_move.
42
431.73 Wed Mar 1 22:49:32 CET 2006
44 - codename "jost"
45 - AIX/Solaris(?) aren't being helpful again, hardcode a value
46 for NAME_MAX and drive with your eyes closed (reported by
47 wcooley@nakedape.cc).
48
491.72 Thu Feb 2 00:40:44 CET 2006
50 - another minor bug in aio_scandir, again, the callback was called
51 twice when the directory can't be stat'ed.
52
531.71 Mon Dec 26 20:20:03 CET 2005
54 - grr, another minor bug in aio_scandir, this time resulting
55 in a runtime error.
56
571.7 Mon Dec 26 19:29:48 CET 2005
58 - aio_scandir errornously called callback twice in some cases.
59 - added AnyEvent example.
60
611.61 Wed Sep 7 19:40:42 CEST 2005
62 - no longer include $Config{libs}, as distros include too much
63 garbage in there that is not installed on typical systems
64 (for example, debian links perl against -lgdbm and many more
65 libraries despite perl not needing it, slowing down startup and
66 wasting memory).
67
681.6 Tue Aug 30 17:44:44 CEST 2005
69 - added aio_readdir, aio_scandir.
70 - added aio_sendfile, including sendfile emulation when sendfile
71 isn't available. Linux, FreeBSD and HP-UX might work (sendfilev
72 support is unavailable on my solaris 8 machine, but preliminary
73 code is there. What's lacking is configury stuff and testing...).
74
751.5 Sat Aug 20 02:32:19 CEST 2005
76 - create the aio threads on demand only (good after forking).
77 - somebody nagged about C89 compatibility, so this release should
78 be C89 compatible, but no guarantees for future ones.
79 - abort when the configure script fails.
80
811.4 Wed Aug 17 08:07:27 CEST 2005
82 - forgot to recreate the pipe after forking, this could cause
83 deadlocks.
84
851.3 Wed Aug 17 07:25:54 CEST 2005
86 - properly propagate exceptions from callbacks, instead of silently
87 eating them.
88 - use a different fork algorithm that avoids recursive callback
89 invocations and reduces fork latency in busy processes.
90 - fix a bug where the buffer scalar in aio_read got assigned the wrong
91 length after reading.
92 - fix a bug where the child would process some outstanding requests
93 from the parent.
94 - make a copy of the callback scalar, to avoid some very uncommon
95 (but valid) usages where the callback scalar changes.
96 - the callback was never freed in aio_read/aio_write.
97 - aio_read/aio_write will now set the readonly flag on the data
98 scalar for better error reporting.
99
1001.2 Wed Aug 17 01:22:58 CEST 2005
101 - verified on cygwin, linux/amd64+ia32+alpha, solaris.
102 - use SvPVbyte for filenames now. You *need* to encode your strings to
103 the external filename encoding first.
104 - fix the bug where filehandles could leak (again).
105 - clarify freebsd situation: make it work and tell me how, or go away
106 with your underdocumented, broken and outdated OS.
107 - fork'ing should now be officially supported (where linux and
108 posix contradict each other, I followed posix).
109 - only call read() once per poll, not twice (speedup).
110 - new functions: aio_rmdir, aio_symlink.
111 - force callback arguments to be undef or a reference, for better
112 error catching.
113
1141.1 Sun Aug 7 05:27:23 CEST 2005
4 - added configure script to detetc availability of some calls. 115 - added configure script to detect availability of some calls.
5 (imperfect, as we cannot detect things like -lrt due it missing 116 (imperfect, as we cannot detect things like -lrt due to missing
6 feedback yet). 117 feedback yet).
7 - emulate fdatasync by fsync, pread/pwrite by unsafe read/write 118 - emulate fdatasync via fsync, pread/pwrite via unsafe read/write
8 and readahead by manual reading on platforms lacking those. 119 and readahead via manual reading on platforms lacking those.

12 compile with it enabled. Probably breaks others. Oh well. 123 compile with it enabled. Probably breaks others. Oh well.
13 - try to be more careful with errno on non-threaded perls. 124 - try to be more careful with errno on non-threaded perls.
125 - cygwins perl insisted on a matching open mode when morphing
126 the fd to an fh.
127 - convert sv's to "byte" encoding in aio_read/aio_write. Might
128 do that for pathnames, too, in the future, so make sure you
129 properly encode your pathnames.

16 - aio_open did not reliably deliver (open) filehandles. 132 - aio_open did not reliably deliver (open) filehandles.
17 - all aio_*-functions keep a reference to the filehandle so 133 - all aio_*-functions keep a reference to the filehandle so
18 it doesn't go away while the aio requests is working on it. 134 it doesn't go away while the aio requests is working on it.
