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

92.33 Tue Jan 23 23:55:41 CET 2007 982.33 Tue Jan 23 23:55:41 CET 2007
10 - fix install path (Andreas J. Koenig). 99 - fix install path (Andreas J. Koenig).
