14TODO: remove fork support, eio_init can be called multiple times maybe
15TODO: "this might change" - no wrklock for malloc, no automatic free in child.
16 - passes testsuite on win32 now (activetstate 5.10.1).
17 - (libeio) fix a deadlock where a wakeup signal could be missed when
18 a timeout occured at the same time.
19 - (libeio) added realpath.
20 - (libeio) added fallocate.
21 - (libeio) disabling sendfile on darwin unfortunately broke the emulation.
22 - (libeio) do not acquire any locks when forking.
23 - (libeio) use fewer time() syscalls when waiting for new requests.
24
253.93 Wed Jun 29 23:44:18 CEST 2011
26 - ECB.H WAS MISSING.
27
283.92 Wed Jun 29 14:45:41 CEST 2011
29 - ecb.h was missing.
30
313.91 Wed Jun 29 13:24:42 CEST 2011
32 - (libeio) work around a Linux (and likely FreeBSD and other
33 kernels) bug where sendfile would not transfer all the requested
34 bytes on large transfers, using a heuristic.
35 - buggy sendfile caused aio_move/copy to sometimes fail for big
36 files (fortunately it checks that the whole file has been
37 transferred...)
38 - use libecb for higher performance and higher portability.
39 - (libeio) disable sendfile on darwin, it's too broken.
40 - disable fork tests on !linux, as only linux supports mixing
41 pthread and fork in perl.
42 - document the fact that fork doesn't work anymore when using
43 this module, on anything !GNU/Linux.
44 - increase timeout in t/04_fork.t, as too many CPAN-tester setups
45 run on a 0.1MHz cpu. Or so.
46
473.9 Fri May 27 02:43:47 CEST 2011
48 - (libeio) fix memory corruption in aio_readdirx for the flags
49 combination READDIR_STAT_ORDER | READDIR_DIRS_FIRST.
50 - add lots of newer POSIX and GNU/Linux-specific open
51 flags.
52
533.8 Sun Mar 27 12:25:33 CEST 2011
54 - use nonstandard but maybe-working-on-bsd fork technique.
55 - support a max_idle value of 0.
56 - support setting of idle timeout value (IO::AIO::idle_timeout).
57
583.72 Fri Feb 11 04:25:38 CET 2011
59 - use _POSIX_MEMLOCK_RANGE to detect mlock/munlock.
60 - aio_mknod always used a dev_t value of 0.
61 - new treescan option: --grep.
62 - add more S_IF macros, and major/minor/makedev "macros".
63
643.71 Thu Dec 30 08:18:46 CET 2010
65 - the numerical result value passed to callbacks did not stringify
66 correctly, due to internal reuse and failure to reset the sv flags.
67 - actually test for posix_[mf]advise, as at least uClibc defines
68 _POSIX_ADVISORY_INFO without actually having any of the required
69 funcitonality. ugh.
70
713.7 Mon Nov 1 23:00:34 CET 2010
72 - implement/add madvise, mmap, munmap, aio_mlockall, munlockall,
73 aio_mlock, munlock, msync and mtouch to @EXPORT_OK.
74 - document the sad state of affairs w.r.t. pthread on many bsds.
75 - do not enable mmap on systems without _POSIX_MAPPED_FILES
76 (openbsd 4.8).
77 - do not leak memory in IO::AIO::mmap when the scalar already
78 had string-data.
79 - add O_RDWR, O_APPEND and O_EXCL symbols and semi-document
80 them.
81 - cache the result IV, for a minor speedup in the common case.
82 - croak when an mmapped-scalar changes location, to detect
83 user-errors better.
84 - fix aio_readlink prototype.
85
863.65 Wed Mar 31 02:45:05 CEST 2010
87 - actually use PATH_MAX instead of NAME_MAX for readlink, as to not
88 cut off long pathnames in aio_readlink (based on patch by
89 Rasmus Andersson).
90 - a double fork partially killed the event pipe (great testcase
91 by dormando). affects IO::AIO, BDB and Async::Interrupt.
92 - suck steve's dick and rename our symbols to avoid colliding
93 with nonstandard identifier spam on the broken os x pseudo-os.
94 affects IO::AIO and BDB.
95
963.6 Mon Jan 11 00:43:39 CET 2010
97 - (libeio) more fixes for the freebsd/apple sendfile - broken by
98 manpage standards, but apparently correct accoridng to actual
99 kernel sources.
100 - add IO::AIO::mmap/munmap support.
101 - add IO::AIO::m(un)lockall support.
102 - clean up manpage.
103
1043.5 Thu Jan 7 21:25:04 CET 2010
105 - (liebio) fix freebsd sendfile (Vanilla Hsu).
106 - (libeio) also fix darwin sendfile that suffered from a similar bug.
107 - add aio_statvfs as interface to statvfs/fstatvfs.
108 - work around buggy symlink() on cygwin in the testsuite.
109 - wtf. freebsd-8.0 actually passes the testsuite! I knew
110 they could implement fork and semaphores one day! cheers!
111
1123.4 Sat Jan 2 15:13:04 CET 2010
113 - (libeio) max_poll_time was not properly converted to ticks.
114 - clarify cancel_subs description.
115 - IO::AIO::sendfile did not actually return the return value
116 from the sendfile call.
117 - implement aio_msync, aio_mtouch.
118 - (libeio) tentatively support darwin in sendfile.
119
1203.31 Thu Nov 12 02:14:29 CET 2009
121 - fix result status documentation of aio_copy, aio_move.
122 - speed up object creation considerably by avoiding
123 hash lookups.
124
1253.3 Wed Aug 5 13:52:58 CEST 2009
126 - use common::sense.
127 - use common schmorp.h header.
128 - allow integers (file descriptors) in addition to file handles.
129 - take advantage of linux' eventfd (but it seems slower on smp?).
130 - use poll not select on posix platforms.
131
1323.261 Wed Jul 1 10:11:51 CEST 2009
133 - more 0S X workarounds (patch by Tokuhiro Matsuno).
134
1353.26 Tue Jun 30 09:33:26 CEST 2009
136 - 0S X of course claims to be posix 2008 but lacks posix_fadvise.
137 try to work around this horribly broken OS in a somewhat hackish
138 way. might help other os's too.
139
1403.25 Sat Jun 27 05:18:26 CEST 2009
141 - added IO::AIO::fadvise and IO::AIO::sendfile.
9 - (libeio) replaced quicksort+insertion sort by a tuned radix 142 - (libeio) replaced quicksort+insertion sort by a tuned radix
10 sort + insertion sort, resulting in comparable runtime (usually 143 sort + insertion sort, resulting in comparable runtime (usually
11 faster) to the old version, but without any ill side effects on 144 faster) to the old version, but without any ill side effects on
12 degenerated (for quicksort) data. 145 degenerated (for quicksort) data.
13 - (libeio) correctly sort dirs by inodes if we have perfect type 146 - (libeio) correctly sort dirs by inodes if we have perfect type
14 knowledge and DIRS_FIRST is used. 147 knowledge and DIRS_FIRST is used.
15 - (libeio) internally the wrong DT_* constants were used, but no 148 - (libeio) internally the wrong DT_* constants were used, but no
16 known system has differing EIO_DT_*/DT_* values, so not an issue. 149 known system has differing EIO_DT_*/DT_* values, so not an issue.
17 - removed a (harmless) assert that was left over on the code 150 - removed a (harmless) assert that was left over on the code
18 but should not have been. 151 but should not have been.
152 - use more correct types (change IO length from IV to VAL64,
153 which makes a difference on systems without 64 bit perls).

203.23 Sat Jun 13 16:57:58 CEST 2009 1553.23 Sat Jun 13 16:57:58 CEST 2009
