3 TODO: better autoconf.pm that can return LIBS etc.
4 TODO: maxidle? exit after idle time?
5
6 - start threads only on (very low) demand.
7 - some tuning applied to random places.
8
9 2.0 Thu Oct 26 18:27:58 CEST 2006
10 - minor incompatibility: max_outstanding semantics have changed.
11 - major rewrite, consider all functionality EXPERIMENTAL.
12 - aio requests can be cancelled.
13 - callbacks can be (re-)set later.
14 - aio requests can choose between 9 priorities.
15 - add aio_group: aio requests can be grouped
16 into composite requests.
17 - generator interface for groups.
18 - add IO::AIO::poll_some.
19 - major documentation improvements.
20 - very minor bugfixes.
21 - add aio_nop for dummy requests.
22 - add aio_busy mainly for benchmarking and debugging.
23 - use "fast" mutexes on linux.
24 - use dynamic (and larger) buffers instead of
25 putting them onto the stack.
26 - optimise x86 and amd64 a bit.
27 - better error checking when ENOMEM.
28 - hopefully fix mem and dirp leaks on fork.
29 - warn about broken perl malloc.
30 - compiles on cygwin (but pread is broken on cygwin
31 which is not detected by autoconf, so you have to
32 edit autoconf/config.h yourself to enable emulation).
33
34 1.8 Sat Jun 24 22:20:44 CEST 2006
35 - add and/or document aio_rename, aio_link, aio_symlink and aio_move.
36
37 1.73 Wed Mar 1 22:49:32 CET 2006
38 - codename "jost"
39 - AIX/Solaris(?) aren't being helpful again, hardcode a value
40 for NAME_MAX and drive with your eyes closed (reported by
41 wcooley@nakedape.cc).
42
43 1.72 Thu Feb 2 00:40:44 CET 2006
44 - another minor bug in aio_scandir, again, the callback was called
45 twice when the directory can't be stat'ed.
46
47 1.71 Mon Dec 26 20:20:03 CET 2005
48 - grr, another minor bug in aio_scandir, this time resulting
49 in a runtime error.
50
51 1.7 Mon Dec 26 19:29:48 CET 2005
52 - aio_scandir errornously called callback twice in some cases.
53 - added AnyEvent example.
54
55 1.61 Wed Sep 7 19:40:42 CEST 2005
56 - no longer include $Config{libs}, as distros include too much
57 garbage in there that is not installed on typical systems
58 (for example, debian links perl against -lgdbm and many more
59 libraries despite perl not needing it, slowing down startup and
60 wasting memory).
61
62 1.6 Tue Aug 30 17:44:44 CEST 2005
63 - added aio_readdir, aio_scandir.
64 - added aio_sendfile, including sendfile emulation when sendfile
65 isn't available. Linux, FreeBSD and HP-UX might work (sendfilev
66 support is unavailable on my solaris 8 machine, but preliminary
67 code is there. What's lacking is configury stuff and testing...).
68
69 1.5 Sat Aug 20 02:32:19 CEST 2005
70 - create the aio threads on demand only (good after forking).
71 - somebody nagged about C89 compatibility, so this release should
72 be C89 compatible, but no guarantees for future ones.
73 - abort when the configure script fails.
74
75 1.4 Wed Aug 17 08:07:27 CEST 2005
76 - forgot to recreate the pipe after forking, this could cause
77 deadlocks.
78
79 1.3 Wed Aug 17 07:25:54 CEST 2005
80 - properly propagate exceptions from callbacks, instead of silently
81 eating them.
82 - use a different fork algorithm that avoids recursive callback
83 invocations and reduces fork latency in busy processes.
84 - fix a bug where the buffer scalar in aio_read got assigned the wrong
85 length after reading.
86 - fix a bug where the child would process some outstanding requests
87 from the parent.
88 - make a copy of the callback scalar, to avoid some very uncommon
89 (but valid) usages where the callback scalar changes.
90 - the callback was never freed in aio_read/aio_write.
91 - aio_read/aio_write will now set the readonly flag on the data
92 scalar for better error reporting.
93
94 1.2 Wed Aug 17 01:22:58 CEST 2005
95 - verified on cygwin, linux/amd64+ia32+alpha, solaris.
96 - use SvPVbyte for filenames now. You *need* to encode your strings to
97 the external filename encoding first.
98 - fix the bug where filehandles could leak (again).
99 - clarify freebsd situation: make it work and tell me how, or go away
100 with your underdocumented, broken and outdated OS.
101 - fork'ing should now be officially supported (where linux and
102 posix contradict each other, I followed posix).
103 - only call read() once per poll, not twice (speedup).
104 - new functions: aio_rmdir, aio_symlink.
105 - force callback arguments to be undef or a reference, for better
106 error catching.
107
108 1.1 Sun Aug 7 05:27:23 CEST 2005
109 - added configure script to detect availability of some calls.
110 (imperfect, as we cannot detect things like -lrt due to missing
111 feedback yet).
112 - emulate fdatasync via fsync, pread/pwrite via unsafe read/write
113 and readahead via manual reading on platforms lacking those.
114 - ported t/03_errors.t+framework by Brad Fitzpatrick
115 from Linux::AIO.
116 - removed XOPEN_SOURCE because stupid solaris 9 doesn't
117 compile with it enabled. Probably breaks others. Oh well.
118 - try to be more careful with errno on non-threaded perls.
119 - cygwins perl insisted on a matching open mode when morphing
120 the fd to an fh.
121 - convert sv's to "byte" encoding in aio_read/aio_write. Might
122 do that for pathnames, too, in the future, so make sure you
123 properly encode your pathnames.
124
125 1.0 Fri Jul 22 10:43:30 CEST 2005
126 - aio_open did not reliably deliver (open) filehandles.
127 - all aio_*-functions keep a reference to the filehandle so
128 it doesn't go away while the aio requests is working on it.
129 - disable warnings in AIO.pm.
130
131 0.9 Wed Jul 20 23:55:04 CEST 2005
132 - allow recursive calls to poll_cb, use less locking calls, too.
133 - fix the Gtk2-example in the SYNOPSIS.
134 - use pread/pwrite not pread64/pwrite64. this was simply a leftover
135 from Linux::AIO.
136 (found by compiling on cygwin. Unfortunately, cygwin declares but
137 does not implement pread/pwrite).
138 - only include <sys/syscall.h> on linux.
139
140 0.5 Tue Jul 12 13:03:09 CEST 2005
141 - removed #include <endian.h>, it's not portable, and we don't
142 need it anyway.
143 - link against -lrt, as it might contain goodies such as fdatasync,
144 and often aio_read, which we do not use yet, but it shouldn't hurt.
145
146 0.4 Mon Jul 11 05:28:25 CEST 2005
147 - added IO::AIO::flush, IO::AIO::poll.
148 - make callback argument optional for all calls.
149
150 0.3 Mon Jul 11 01:42:37 CEST 2005
151 - restructured manpage.
152 - added SYNOPSIS with examples for Event, Glib, Tk.
153 - remove explicit context support so I don't have to maintain
154 it for threaded perls (i.e. it should work now :).
155
156 0.2 Sun Jul 10 22:57:12 CEST 2005
157 - return immediately from poll_wait if nreqs==0.
158 - get rid of the request pipe and use faster thread-thread
159 communications for most requests and responses.
160
161 0.1
162 - cloned from Linux::AIO, which is very similar.
163
