6 - AIX isn't being helpful again, hardcode a value for NAME_MAX 10 - after fork, invest some work to make sure that the poll_fileno
11 stays stable (by dup2'ing the new fd over the old one), to make
12 it easier for programs/libs that don't control their forking
13 behaviour and cannot recreate their watchers.

152.4 Sun Aug 5 18:44:22 CEST 2007
16 - add aio_truncate, aio_chmod, aio_chown, aio_utime (linux
17 successfully demonstrated that you can block on futimes...).
18 - allow undef as fileoffset for aio_read/write and use read/write(2)
19 internally (useful for sockets or O_APPEND handles).
20 - allow undef for length in aio_write.
21 - negative dataoffsets work as expected now in aio_read/aio_write.
22 - use NV instead of UV for 32 bit perls and file offsets, as NVs
23 have a larger range then.
24 - shared code between BDB and IO::AIO.
25 - aio_busy was completely broken. now fixed.
26 - readahead emulation now returns something.
27 - correctly set errno to ENOSYS on unimplemented functions
28 (should never happen, though).
29 - large changes to make it partially compile and run on win32,
30 but win32 lacks too much functionality, and perl overrides way
31 too many functions with crashing versions.
32
332.33 Tue Jan 23 23:55:41 CET 2007
34 - fix install path (Andreas J. Koenig).
35
362.32 Mon Jan 22 16:56:23 CET 2007
37 - added aio_rmtree.
38 - wow, aio_mkdir was missing.
39 - aio_load did return undef on error, not -1.
40 - use prefixexp not prefix in autoconf.pm
41 (suggested by ... rt.cpan.org unreachable).
42 - avoid installing autoconf.pm.
43
442.31 Sat Jan 6 03:46:02 CET 2007
45 - added aio_load.
46
472.3 Sat Dec 23 05:48:07 CET 2006
48 - fix off-by-one bug in aio_read, causing memory corruption
49 or crashes.
50
512.21 Fri Dec 22 05:03:38 CET 2006
52 - minor doc updates.
53 - minor cleanups.
54 - IO::AIO::poll returns request count.
55 - undocumented and unfinished async-signal-reporting.
56
572.2 Tue Oct 31 00:31:00 CET 2006
58 - minor doc updates.
59 - added aio_readlink.
60 - properly zero-terminate aio_read buffer.
61 - fix aio_read/write with nonzero dataoffset.
62 - reduced size of aio request structure.
63 - better diagnostics when pathnames etc. are not byte-encoded;
64 do not leak request in that case, either.
65
662.1 Sun Oct 29 02:01:57 CET 2006
67 - INCOMPATIBLE CHANGE: replace IO::AIO::poll_some by
68 IO::AIO::max_poll_reqs and IO::AIO::max_poll_time.
69 - fix a bug in aio_move where it would fail everytime
70 it would have to copy files manually.
71 - doc updates.
72 - start threads only on (very low) demand.
73 - end superfluous threads automatically after 10s idling.
74 - add IO::AIO::max_idle to control this.
75 - some tuning applied to random places.
76 - add aio_mknod.
77
782.0 Thu Oct 26 18:27:58 CEST 2006
79 - minor incompatibility: max_outstanding semantics have changed.
80 - major rewrite, consider all functionality EXPERIMENTAL.
81 - aio requests can be cancelled.
82 - callbacks can be (re-)set later.
83 - aio requests can choose between 9 priorities.
84 - add aio_group: aio requests can be grouped
85 into composite requests.
86 - generator interface for groups.
87 - add IO::AIO::poll_some.
88 - major documentation improvements.
89 - very minor bugfixes.
90 - add aio_nop for dummy requests.
91 - add aio_busy mainly for benchmarking and debugging.
92 - use "fast" mutexes on linux.
93 - use dynamic (and larger) buffers instead of
94 putting them onto the stack.
95 - optimise x86 and amd64 a bit.
96 - better error checking when ENOMEM.
97 - hopefully fix mem and dirp leaks on fork.
98 - warn about broken perl malloc.
99 - compiles on cygwin (but pread is broken on cygwin
100 which is not detected by autoconf, so you have to
101 edit autoconf/config.h yourself to enable emulation).
102
1031.8 Sat Jun 24 22:20:44 CEST 2006
104 - add and/or document aio_rename, aio_link, aio_symlink and aio_move.

1061.73 Wed Mar 1 22:49:32 CET 2006
107 - codename "jost"
108 - AIX/Solaris(?) aren't being helpful again, hardcode a value
7 and drive with your eyes closed (reported by wcooley@nakedape.cc). 109 for NAME_MAX and drive with your eyes closed (reported by
110 wcooley@nakedape.cc).
