- fix a memory leak on aio_readlink. |
11 |
|
|
- bring back working fchmod. |
12 |
root |
1.151 |
- nop and busy now set result to 0. |

3.01 Sun May 11 03:07:03 CEST 2008 |
16 |
|
|
- (libeio) make it compile on systems without readahead or readdir_r. |
17 |
root |
1.148 |
- (libeio) improve configure check for readahead availability. |
18 |
|
|
- do not try to link against -lrt. |
19 |
root |
1.147 |
- use a separate configure script for IO::AIO (not the libeio one). |
20 |
|
|
|
21 |
root |
1.146 |
3.0 Sun May 11 00:57:14 CEST 2008 |
22 |
root |
1.145 |
- added bin/treescan to the distribution. |
23 |
|
|
- switched to using libeio. |
24 |
|
|
- LOTS OF INCOMPATIBLE CHANGES: |
25 |
|
|
- remove signal functionality, it is not worth the effort. |
26 |
|
|
- max_outstanding no longer returns the previous number of requests. |
27 |
|
|
- poll_cb no longer returns number of requests. |

2.62 Sat Apr 26 13:59:33 CEST 2008 |
30 |
root |
1.141 |
- port to solaris perls configured for old posix |
31 |
|
|
(analysed by Jost Krieger). |
32 |
root |
1.142 |
- keep a reference to the perl filehandle object in aio_close, |
33 |
|
|
so it doesn't get closed prematurely, leading to ugly races. |
34 |
root |
1.141 |
|

root |
1.140 |
2.61 Wed Apr 16 18:45:02 CEST 2008 |
36 |
root |
1.137 |
- fix treescan output duplication and improve output ordering. |
37 |
|
|
also display files given on the commandline. |
38 |
root |
1.140 |
- use a different algorithm for aio_close that is faster |
39 |
|
|
and probably has even lower chances of blocking. |
40 |
root |
1.138 |
- do our own stack memory management for threads - linux |
41 |
|
|
allocates outrageous amounts of VM (not so bad unless you |
42 |
|
|
use mlockall...), which severely limits the number of threads |
43 |
root |
1.139 |
on 32-bit arches: stack size is the larger of PTHREAD_STACK_MIN |
44 |
|
|
and 4096 * sizeof (long) (usually this is 16..64k). |
45 |

root |
1.136 |
2.6 Sun Mar 30 08:28:11 CEST 2008 |
47 |
root |
1.134 |
- added aio_sync. |
48 |
root |
1.135 |
- added aio_pathsync. |
49 |
root |
1.136 |
- fix prototypes of (void) functions. |

root |
1.134 |
|
51 |
root |
1.133 |
2.51 Sat Oct 6 16:04:54 CEST 2007 |
52 |
|
|
- perlio isn't generally threadsafe, so aio_close could not work reliably. |
53 |
|
|
aio_close now tries a safe hack that might not be that asynchronous |
54 |
|
|
(see the manpage for details). |
55 |
|
|
- discard callback return values as to not grow the stack endlessly |
56 |
|
|
when poll_cb handles many requests without returning. |
57 |
|
|
- minor code cleanups. |
58 |
|
|
|
59 |
root |
1.132 |
2.5 Thu Oct 4 14:49:08 CEST 2007 |
60 |
root |
1.131 |
- replaced _fd2fh with faster xs code. |
61 |
|
|
- aio_close will now try to do "the right thing" and thus might |
62 |
|
|
work sensibly for the very first time. |
63 |
|
|
|
64 |
root |
1.130 |
2.41 Mon Sep 24 21:28:21 CEST 2007 |
65 |
root |
1.129 |
- after fork, invest some work to make sure that the poll_fileno |
66 |
|
|
stays stable (by dup2'ing the new fd over the old one), to make |
67 |
|
|
it easier for programs/libs that don't control their forking |
68 |
|
|
behaviour and cannot recreate their watchers. |
69 |
|
|

70 |
root |
1.128 |
2.4 Sun Aug 5 18:44:22 CEST 2007 |
71 |
root |
1.127 |
- add aio_truncate, aio_chmod, aio_chown, aio_utime (linux |
72 |
|
|
successfully demonstrated that you can block on futimes...). |
73 |
root |
1.124 |
- allow undef as fileoffset for aio_read/write and use read/write(2) |
74 |
|
|
internally (useful for sockets or O_APPEND handles). |
75 |
root |
1.126 |
- allow undef for length in aio_write. |
76 |
|
|
- negative dataoffsets work as expected now in aio_read/aio_write. |
77 |
root |
1.124 |
- use NV instead of UV for 32 bit perls and file offsets, as NVs |
78 |
root |
1.125 |
have a larger range then. |
79 |
root |
1.120 |
- shared code between BDB and IO::AIO. |
80 |
root |
1.127 |
- aio_busy was completely broken. now fixed. |
81 |
|
|
- readahead emulation now returns something. |
82 |
root |
1.121 |
- correctly set errno to ENOSYS on unimplemented functions |
83 |
|
|
(should never happen, though). |
84 |
root |
1.127 |
- large changes to make it partially compile and run on win32, |
85 |
|
|
but win32 lacks too much functionality, and perl overrides way |
86 |
|
|
too many functions with crashing versions. |
87 |

|
88 |
root |
1.119 |
2.33 Tue Jan 23 23:55:41 CET 2007 |

root |
1.118 |
2.32 Mon Jan 22 16:56:23 CET 2007 |
92 |
root |
1.114 |
- added aio_rmtree. |
93 |
root |
1.115 |
- wow, aio_mkdir was missing. |
94 |
root |
1.116 |
- aio_load did return undef on error, not -1. |
95 |
root |
1.117 |
- use prefixexp not prefix in autoconf.pm |
96 |
|
|
(suggested by ... rt.cpan.org unreachable). |
97 |
root |
1.118 |
- avoid installing autoconf.pm. |

2.3 Sat Dec 23 05:48:07 CET 2006 |
103 |
|

- fix off-by-one bug in aio_read, causing memory corruption |
104 |
|
|
or crashes. |
105 |
|
|

106 |
root |
1.110 |
2.21 Fri Dec 22 05:03:38 CET 2006 |
107 |
root |
1.108 |
- minor doc updates. |
108 |
root |
1.107 |
- minor cleanups. |
109 |
|
|
- IO::AIO::poll returns request count. |
110 |
root |
1.109 |

root |
1.103 |
2.2 Tue Oct 31 00:31:00 CET 2006 |
113 |
root |
1.100 |
- minor doc updates. |
114 |
root |
1.101 |
- added aio_readlink. |
115 |
|
|
- properly zero-terminate aio_read buffer. |
116 |
|
|
- fix aio_read/write with nonzero dataoffset. |
117 |
root |
1.104 |
- reduced size of aio request structure. |
118 |
root |
1.106 |
- better diagnostics when pathnames etc. are not byte-encoded; |
119 |
root |
1.105 |
do not leak request in that case, either. |
120 |
root |
1.94 |

root |
1.99 |
2.1 Sun Oct 29 02:01:57 CET 2006 |
122 |
root |
1.98 |
- INCOMPATIBLE CHANGE: replace IO::AIO::poll_some by |
123 |
|
|
IO::AIO::max_poll_reqs and IO::AIO::max_poll_time. |
124 |
root |
1.95 |
- fix a bug in aio_move where it would fail everytime |
125 |
|
|
it would have to copy files manually. |
126 |
root |
1.98 |
- doc updates. |
127 |
root |
1.94 |
- start threads only on (very low) demand. |
128 |
root |
1.97 |
- end superfluous threads automatically after 10s idling. |
129 |
root |
1.98 |
- add IO::AIO::max_idle to control this. |
130 |
root |
1.94 |
- some tuning applied to random places. |
131 |
root |
1.95 |
- add aio_mknod. |
132 |

133 |
root |
1.92 |
2.0 Thu Oct 26 18:27:58 CEST 2006 |
134 |
root |
1.90 |
- minor incompatibility: max_outstanding semantics have changed. |
135 |
root |
1.86 |
- major rewrite, consider all functionality EXPERIMENTAL. |
136 |
root |
1.68 |
- aio requests can be cancelled. |
137 |
root |
1.81 |
- callbacks can be (re-)set later. |
138 |
root |
1.93 |
- aio requests can choose between 9 priorities. |
139 |
root |
1.83 |
- add aio_group: aio requests can be grouped |
140 |
|
|
into composite requests. |
141 |
|
|
- generator interface for groups. |
142 |
root |
1.89 |
- add IO::AIO::poll_some. |
143 |
root |
1.72 |
- major documentation improvements. |
144 |
|
|
- very minor bugfixes. |
145 |
root |
1.76 |
- add aio_nop for dummy requests. |
146 |
root |
1.84 |
- add aio_busy mainly for benchmarking and debugging. |
147 |
root |
1.79 |
- use "fast" mutexes on linux. |
148 |
root |
1.80 |
- use dynamic (and larger) buffers instead of |
149 |
|
|
putting them onto the stack. |
150 |
|
|
- optimise x86 and amd64 a bit. |
151 |
|
|
- better error checking when ENOMEM. |
152 |
root |
1.85 |
- hopefully fix mem and dirp leaks on fork. |
153 |
root |
1.92 |
- warn about broken perl malloc. |
154 |
root |
1.88 |
- compiles on cygwin (but pread is broken on cygwin |
155 |
|
|
which is not detected by autoconf, so you have to |
156 |
|
|
edit autoconf/config.h yourself to enable emulation). |
157 |
root |
1.68 |

158 |
root |
1.67 |
1.8 Sat Jun 24 22:20:44 CEST 2006 |
159 |
root |
1.66 |
- add and/or document aio_rename, aio_link, aio_symlink and aio_move. |
160 |
|
|
|
161 |
root |
1.65 |
1.73 Wed Mar 1 22:49:32 CET 2006 |
162 |
|
|
- codename "jost" |
163 |
|
|
- AIX/Solaris(?) aren't being helpful again, hardcode a value |
164 |
|
|
for NAME_MAX and drive with your eyes closed (reported by |
165 |
|
|
wcooley@nakedape.cc). |
166 |

root |
1.62 |
1.72 Thu Feb 2 00:40:44 CET 2006 |
168 |
root |
1.61 |
- another minor bug in aio_scandir, again, the callback was called |
169 |
|
|
twice when the directory can't be stat'ed. |
170 |
|
|
|
171 |
root |
1.60 |
1.71 Mon Dec 26 20:20:03 CET 2005 |
172 |
|
|
- grr, another minor bug in aio_scandir, this time resulting |
173 |
|
|
in a runtime error. |
174 |
|
|
|
175 |
root |
1.59 |
1.7 Mon Dec 26 19:29:48 CET 2005 |
176 |
root |
1.58 |
- aio_scandir errornously called callback twice in some cases. |
177 |
root |
1.57 |
- added AnyEvent example. |
178 |
|
|
|
179 |
root |
1.55 |
1.61 Wed Sep 7 19:40:42 CEST 2005 |
180 |
root |
1.54 |
- no longer include $Config{libs}, as distros include too much |
181 |
root |
1.56 |
garbage in there that is not installed on typical systems |
182 |
root |
1.54 |
(for example, debian links perl against -lgdbm and many more |
183 |
|
|
libraries despite perl not needing it, slowing down startup and |
184 |
|
|
wasting memory). |
185 |

|
|
186 |
root |
1.53 |
1.6 Tue Aug 30 17:44:44 CEST 2005 |
187 |
|
|
- added aio_readdir, aio_scandir. |
188 |
root |
1.51 |
- added aio_sendfile, including sendfile emulation when sendfile |
189 |
|
|
isn't available. Linux, FreeBSD and HP-UX might work (sendfilev |
190 |
|
|
support is unavailable on my solaris 8 machine, but preliminary |
191 |
|
|
code is there. What's lacking is configury stuff and testing...). |

193 |
root |
1.44 |
1.5 Sat Aug 20 02:32:19 CEST 2005 |
194 |
root |
1.51 |
- create the aio threads on demand only (good after forking). |
195 |
root |
1.41 |
- somebody nagged about C89 compatibility, so this release should |
196 |
root |
1.42 |
be C89 compatible, but no guarantees for future ones. |
197 |
root |
1.43 |
- abort when the configure script fails. |
198 |
root |
1.41 |
|
199 |
root |
1.40 |
1.4 Wed Aug 17 08:07:27 CEST 2005 |
200 |
root |
1.93 |
- forgot to recreate the pipe after forking, this could cause |
201 |
root |
1.40 |
deadlocks. |
202 |
|
|
|
203 |
root |
1.39 |
1.3 Wed Aug 17 07:25:54 CEST 2005 |
204 |
root |
1.33 |
- properly propagate exceptions from callbacks, instead of silently |
205 |
|
|
eating them. |
206 |
root |
1.38 |
- use a different fork algorithm that avoids recursive callback |
207 |
|
|
invocations and reduces fork latency in busy processes. |
208 |
root |
1.37 |
- fix a bug where the buffer scalar in aio_read got assigned the wrong |
209 |
|
|
length after reading. |
210 |
|
|
- fix a bug where the child would process some outstanding requests |
211 |
|
|
from the parent. |
212 |
|
|
- make a copy of the callback scalar, to avoid some very uncommon |
213 |
|
|
(but valid) usages where the callback scalar changes. |
214 |
|
|
- the callback was never freed in aio_read/aio_write. |
215 |
root |
1.38 |
- aio_read/aio_write will now set the readonly flag on the data |
216 |
|
|
scalar for better error reporting. |
217 |
root |
1.33 |
|
218 |
root |
1.32 |
1.2 Wed Aug 17 01:22:58 CEST 2005 |
219 |
|
|
- verified on cygwin, linux/amd64+ia32+alpha, solaris. |
220 |
root |
1.31 |
- use SvPVbyte for filenames now. You *need* to encode your strings to |
221 |
|
|
the external filename encoding first. |
222 |
root |
1.32 |
- fix the bug where filehandles could leak (again). |
223 |
root |
1.31 |
- clarify freebsd situation: make it work and tell me how, or go away |
224 |
|
|
with your underdocumented, broken and outdated OS. |
225 |
|
|
- fork'ing should now be officially supported (where linux and |
226 |
|
|
posix contradict each other, I followed posix). |
227 |
root |
1.32 |
- only call read() once per poll, not twice (speedup). |
228 |
|
|
- new functions: aio_rmdir, aio_symlink. |
229 |
root |
1.31 |
- force callback arguments to be undef or a reference, for better |
230 |
|
|
error catching. |
231 |
root |
1.1 |
|
232 |
root |
1.29 |
1.1 Sun Aug 7 05:27:23 CEST 2005 |
233 |
root |
1.25 |
- added configure script to detect availability of some calls. |
234 |
root |
1.27 |
(imperfect, as we cannot detect things like -lrt due to missing |
235 |
root |
1.23 |
feedback yet). |
236 |
root |
1.27 |
- emulate fdatasync via fsync, pread/pwrite via unsafe read/write |
237 |
|
|
and readahead via manual reading on platforms lacking those. |
238 |
root |
1.19 |
- ported t/03_errors.t+framework by Brad Fitzpatrick |
239 |
|
|
from Linux::AIO. |
240 |
root |
1.18 |
- removed XOPEN_SOURCE because stupid solaris 9 doesn't |
241 |
|
|
compile with it enabled. Probably breaks others. Oh well. |
242 |
root |
1.24 |
- try to be more careful with errno on non-threaded perls. |
243 |
root |
1.26 |
- cygwins perl insisted on a matching open mode when morphing |
244 |
|
|
the fd to an fh. |
245 |
root |
1.28 |
- convert sv's to "byte" encoding in aio_read/aio_write. Might |
246 |
|
|
do that for pathnames, too, in the future, so make sure you |
247 |
|
|
properly encode your pathnames. |

|
249 |
root |
1.17 |
1.0 Fri Jul 22 10:43:30 CEST 2005 |
250 |
|
|
- aio_open did not reliably deliver (open) filehandles. |
251 |
root |
1.16 |
- all aio_*-functions keep a reference to the filehandle so |
252 |
|
|
it doesn't go away while the aio requests is working on it. |
253 |
|
|
- disable warnings in AIO.pm. |
254 |
|

|
255 |
root |
1.15 |
0.9 Wed Jul 20 23:55:04 CEST 2005 |
256 |
|
|
- allow recursive calls to poll_cb, use less locking calls, too. |
257 |
|
|
- fix the Gtk2-example in the SYNOPSIS. |
258 |
root |
1.14 |
- use pread/pwrite not pread64/pwrite64. this was simply a leftover |
259 |
|
|
from Linux::AIO. |
260 |
|
|
(found by compiling on cygwin. Unfortunately, cygwin declares but |
261 |
|
|
does not implement pread/pwrite). |
262 |
|
|
- only include <sys/syscall.h> on linux. |
263 |

- removed #include <endian.h>, it's not portable, and we don't |

|
|
need it anyway. |
267 |
|
|
- link against -lrt, as it might contain goodies such as fdatasync, |
268 |
|
|
and often aio_read, which we do not use yet, but it shouldn't hurt. |
