|
|
16 | - (libeio) added realpath. |
|
|
17 | - (libeio) disabling sendfile on darwin unfortunately broke it. |
|
|
18 | |
|
|
19 | 3.93 Wed Jun 29 23:44:18 CEST 2011 |
|
|
20 | - ECB.H WAS MISSING. |
|
|
21 | |
|
|
22 | 3.92 Wed Jun 29 14:45:41 CEST 2011 |
|
|
23 | - ecb.h was missing. |
|
|
24 | |
|
|
25 | 3.91 Wed Jun 29 13:24:42 CEST 2011 |
|
|
26 | - (libeio) work around a Linux (and likely FreeBSD and other |
|
|
27 | kernels) bug where sendfile would not transfer all the requested |
|
|
28 | bytes on large transfers, using a heuristic. |
|
|
29 | - buggy sendfile caused aio_move/copy to sometimes fail for big |
|
|
30 | files (fortunately it checks that the whole file has been |
|
|
31 | transferred...) |
|
|
32 | - use libecb for higher performance and higher portability. |
|
|
33 | - (libeio) disable sendfile on darwin, it's too broken. |
|
|
34 | - disable fork tests on !linux, as only linux supports mixing |
|
|
35 | pthread and fork in perl. |
|
|
36 | - document the fact that fork doesn't work anymore when using |
|
|
37 | this module, on anything !GNU/Linux. |
|
|
38 | - increase timeout in t/04_fork.t, as too many CPAN-tester setups |
|
|
39 | run on a 0.1MHz cpu. Or so. |
|
|
40 | |
|
|
41 | 3.9 Fri May 27 02:43:47 CEST 2011 |
|
|
42 | - (libeio) fix memory corruption in aio_readdirx for the flags |
|
|
43 | combination READDIR_STAT_ORDER | READDIR_DIRS_FIRST. |
|
|
44 | - add lots of newre POSIX and GNU/Linux-specific open |
|
|
45 | flags. |
|
|
46 | |
|
|
47 | 3.8 Sun Mar 27 12:25:33 CEST 2011 |
|
|
48 | - use nonstandard but maybe-working-on-bsd fork technique. |
|
|
49 | - support a max_idle value of 0. |
|
|
50 | - support setting of idle timeout value (IO::AIO::idle_timeout). |
|
|
51 | |
|
|
52 | 3.72 Fri Feb 11 04:25:38 CET 2011 |
|
|
53 | - use _POSIX_MEMLOCK_RANGE to detect mlock/munlock. |
|
|
54 | - aio_mknod always used a dev_t value of 0. |
|
|
55 | - new treescan option: --grep. |
|
|
56 | - add more S_IF macros, and major/minor/makedev "macros". |
|
|
57 | |
|
|
58 | 3.71 Thu Dec 30 08:18:46 CET 2010 |
|
|
59 | - the numerical result value passed to callbacks did not stringify |
|
|
60 | correctly, due to internal reuse and failure to reset the sv flags. |
|
|
61 | - actually test for posix_[mf]advise, as at least uClibc defines |
|
|
62 | _POSIX_ADVISORY_INFO without actually having any of the required |
|
|
63 | funcitonality. ugh. |
|
|
64 | |
|
|
65 | 3.7 Mon Nov 1 23:00:34 CET 2010 |
|
|
66 | - implement/add madvise, mmap, munmap, aio_mlockall, munlockall, |
|
|
67 | aio_mlock, munlock, msync and mtouch to @EXPORT_OK. |
|
|
68 | - document the sad state of affairs w.r.t. pthread on many bsds. |
|
|
69 | - do not enable mmap on systems without _POSIX_MAPPED_FILES |
|
|
70 | (openbsd 4.8). |
|
|
71 | - do not leak memory in IO::AIO::mmap when the scalar already |
|
|
72 | had string-data. |
|
|
73 | - add O_RDWR, O_APPEND and O_EXCL symbols and semi-document |
|
|
74 | them. |
|
|
75 | - cache the result IV, for a minor speedup in the common case. |
|
|
76 | - croak when an mmapped-scalar changes location, to detect |
|
|
77 | user-errors better. |
|
|
78 | - fix aio_readlink prototype. |
|
|
79 | |
|
|
80 | 3.65 Wed Mar 31 02:45:05 CEST 2010 |
|
|
81 | - actually use PATH_MAX instead of NAME_MAX for readlink, as to not |
|
|
82 | cut off long pathnames in aio_readlink (based on patch by |
|
|
83 | Rasmus Andersson). |
|
|
84 | - a double fork partially killed the event pipe (great testcase |
|
|
85 | by dormando). affects IO::AIO, BDB and Async::Interrupt. |
|
|
86 | - suck steve's dick and rename our symbols to avoid colliding |
|
|
87 | with nonstandard identifier spam on the broken os x pseudo-os. |
|
|
88 | affects IO::AIO and BDB. |
|
|
89 | |
|
|
90 | 3.6 Mon Jan 11 00:43:39 CET 2010 |
|
|
91 | - (libeio) more fixes for the freebsd/apple sendfile - broken by |
|
|
92 | manpage standards, but apparently correct accoridng to actual |
|
|
93 | kernel sources. |
|
|
94 | - add IO::AIO::mmap/munmap support. |
|
|
95 | - add IO::AIO::m(un)lockall support. |
|
|
96 | - clean up manpage. |
|
|
97 | |
|
|
98 | 3.5 Thu Jan 7 21:25:04 CET 2010 |
|
|
99 | - (liebio) fix freebsd sendfile (Vanilla Hsu). |
|
|
100 | - (libeio) also fix darwin sendfile that suffered from a similar bug. |
|
|
101 | - add aio_statvfs as interface to statvfs/fstatvfs. |
|
|
102 | - work around buggy symlink() on cygwin in the testsuite. |
|
|
103 | - wtf. freebsd-8.0 actually passes the testsuite! I knew |
|
|
104 | they could implement fork and semaphores one day! cheers! |
|
|
105 | |
|
|
106 | 3.4 Sat Jan 2 15:13:04 CET 2010 |
|
|
107 | - (libeio) max_poll_time was not properly converted to ticks. |
|
|
108 | - clarify cancel_subs description. |
|
|
109 | - IO::AIO::sendfile did not actually return the return value |
|
|
110 | from the sendfile call. |
|
|
111 | - implement aio_msync, aio_mtouch. |
|
|
112 | - (libeio) tentatively support darwin in sendfile. |
|
|
113 | |
|
|
114 | 3.31 Thu Nov 12 02:14:29 CET 2009 |
|
|
115 | - fix result status documentation of aio_copy, aio_move. |
|
|
116 | - speed up object creation considerably by avoiding |
|
|
117 | hash lookups. |
|
|
118 | |
|
|
119 | 3.3 Wed Aug 5 13:52:58 CEST 2009 |
|
|
120 | - use common::sense. |
|
|
121 | - use common schmorp.h header. |
|
|
122 | - allow integers (file descriptors) in addition to file handles. |
|
|
123 | - take advantage of linux' eventfd (but it seems slower on smp?). |
|
|
124 | - use poll not select on posix platforms. |
|
|
125 | |
|
|
126 | 3.261 Wed Jul 1 10:11:51 CEST 2009 |
|
|
127 | - more 0S X workarounds (patch by Tokuhiro Matsuno). |
|
|
128 | |
|
|
129 | 3.26 Tue Jun 30 09:33:26 CEST 2009 |
|
|
130 | - 0S X of course claims to be posix 2008 but lacks posix_fadvise. |
|
|
131 | try to work around this horribly broken OS in a somewhat hackish |
|
|
132 | way. might help other os's too. |
|
|
133 | |
|
|
134 | 3.25 Sat Jun 27 05:18:26 CEST 2009 |
|
|
135 | - added IO::AIO::fadvise and IO::AIO::sendfile. |
|
|
136 | - (libeio) replaced quicksort+insertion sort by a tuned radix |
|
|
137 | sort + insertion sort, resulting in comparable runtime (usually |
|
|
138 | faster) to the old version, but without any ill side effects on |
|
|
139 | degenerated (for quicksort) data. |
|
|
140 | - (libeio) correctly sort dirs by inodes if we have perfect type |
|
|
141 | knowledge and DIRS_FIRST is used. |
|
|
142 | - (libeio) internally the wrong DT_* constants were used, but no |
|
|
143 | known system has differing EIO_DT_*/DT_* values, so not an issue. |
|
|
144 | - removed a (harmless) assert that was left over on the code |
|
|
145 | but should not have been. |
|
|
146 | - use more correct types (change IO length from IV to VAL64, |
|
|
147 | which makes a difference on systems without 64 bit perls). |
|
|
148 | |
|
|
149 | 3.23 Sat Jun 13 16:57:58 CEST 2009 |
|
|
150 | - fix off-by-one bug in aio_readdir that was introduced in the |
|
|
151 | rushed 3.22 release. |
|
|
152 | |
|
|
153 | 3.22 Sat Jun 13 15:32:40 CEST 2009 |
|
|
154 | - speed up readdirx sort algorithm slightly. |
|
|
155 | - bin/treescan was missing from distro tarball. |
|
|
156 | |
|
|
157 | 3.21 Fri Jun 12 18:45:53 CEST 2009 |
|
|
158 | - new options --dirs and --files for treescan. |
|
|
159 | - install bin/treescan by default. |
|
|
160 | - (libeio) aio_readdir can now be cancelled while executing. |
|
|
161 | - fix a printf format string for 64 bit systems (could lead |
|
|
162 | to problems on big endian 64 bit systems). |
|
|
163 | - do not use qsort() but our own algorithm: glibc initialises |
|
|
164 | the whole locale and I/O subsystem inside qsort, causing |
|
|
165 | a stack overflow on 32 bit machines. The new sort uses much less |
|
|
166 | stack and is more than twice as fast in typical situations. |
|
|
167 | |
|
|
168 | 3.2 Sun Jun 7 20:30:05 CEST 2009 |
|
|
169 | - (libeio) pwrite emulation was even more flawed than intended and did |
|
|
170 | not restore the file offset. |
|
|
171 | - add aio_readdirx, which can return inode and filetype and sort |
|
|
172 | the names in various ways. |
|
|
173 | - unfortunately, utime, chmod, chown on an open file that has just |
|
|
174 | been written can easily block, which caused aio_copy to block the |
|
|
175 | process. no more! |
|
|
176 | - no longer rely on dst path in aio_copy when futime is available. |
|
|
177 | |
|
|
178 | 3.19 Tue Apr 21 22:05:21 CEST 2009 |
|
|
179 | - more perl 5.10 workarounds for aio_read and write. |
|
|
180 | - aio_write no longer modifies the sv (if possible). |
|
|
181 | - aio_read now works correctly with magic values. |
|
|
182 | |
|
|
183 | 3.18 Sun Apr 19 21:17:32 CEST 2009 |
|
|
184 | - better diagnostics when some aio_* functions get passed an illegal fh. |
|
|
185 | - try to avoid crashes due to incompatible 5.10 API changes. grmbl. |
|
|
186 | |
|
|
187 | 3.17 Thu Nov 20 08:45:36 CET 2008 |
|
|
188 | - (libeio) added aio_sync_file_range (untested). |
|
|
189 | - add aio_busy to @IO::AIO::AIO_REQ. |
|
|
190 | |
|
|
191 | 3.16 Wed Oct 22 18:28:01 CEST 2008 |
|
|
192 | - use SvREFCNT_inc instead of SvREFCNT_inc_NN in a non-speed critical |
|
|
193 | part to improve portability to perl 5.8 (reported by szymon). |
|
|
194 | |
|
|
195 | 3.15 Mon Oct 13 00:39:55 CEST 2008 |
|
|
196 | - automatic removal of feeders was broken. |
|
|
197 | - (libeio) use a more robust method to detect whether a feeder |
|
|
198 | has added something to the group or not. |
|
|
199 | |
|
|
200 | 3.1 Thu Oct 2 13:34:40 CEST 2008 |
|
|
201 | - pre-deref the passed callback object, for increased speed |
|
|
202 | and decreased memory usage. |
|
|
203 | - call on_next_submit callback even for aio_group - impact unknown, |
|
|
204 | but seems more correct. |
|
|
205 | - $req->cb now returns the original callback. |
|
|
206 | - (libeio) pass EIO_GROUP/aio_group requests through the queue without |
|
|
207 | requiring a thread switch. |
|
|
208 | - (libeio) status code of aio_futime and aio_utime was always passed 0. |
|
|
209 | - do some other ยต-optimisations. |
|
|
210 | |
|
|
211 | 3.07 Sat Aug 2 16:06:13 CEST 2008 |
|
|
212 | - do not include LIBS in autoconf tests. |
|
|
213 | |
|
|
214 | 3.06 Tue Jul 15 12:41:32 CEST 2008 |
|
|
215 | - move preadwritelock definition before it's first reference, |
|
|
216 | to make it compile again on broken platforms (they still exist) |
|
|
217 | or badly cofngiured perls (redhat...), reported by Rob Bloodgood. |
|
|
218 | |
|
|
219 | 3.05 Thu Jun 19 23:23:52 CEST 2008 |
|
|
220 | - work around perl overriding readdir etc. with thread-unsafe |
|
|
221 | (sic!) versions. |
|
|
222 | |
|
|
223 | 3.04 Wed Jun 18 01:35:38 CEST 2008 |
|
|
224 | - (libeio) fix eio_mknod, which confused it's arguments. |
|
|
225 | - (libeio) do not use readdir_r, as Ulrich Drepper pointed out that this |
|
|
226 | is stupid. |
|
|
227 | - (libeio) fix eio__readahead prototype, patch by Jost Krieger. |
|
|
228 | - (libeio) fix a bug that could potentially cause IO::AIO |
|
|
229 | not to get initialised properly. |
|
|
230 | |
|
|
231 | 3.03 Thu May 29 05:33:30 CEST 2008 |
|
|
232 | - (libeio) correctly call pthread_attr_destroy (). |
|
|
233 | - (libeio) work around broken bsd headers once more. |
|
|
234 | - reduce shared library size again by not including wrappers. |
|
|
235 | - max_outstanding could cause poll to enter a busy-waiting loop. |
|
|
236 | - document the new IO::AIO::poll_cb result value. |
|
|
237 | |
|
|
238 | 3.02 Mon May 12 02:32:02 CEST 2008 |
|
|
239 | - fix a memory leak on aio_readlink. |
|
|
240 | - bring back working fchmod. |
|
|
241 | - nop and busy now set result to 0. |
|
|
242 | - set errno to ENOMEM when allocation fails. |
|
|
243 | |
|
|
244 | 3.01 Sun May 11 03:07:03 CEST 2008 |
|
|
245 | - (libeio) make it compile on systems without readahead or readdir_r. |
|
|
246 | - (libeio) improve configure check for readahead availability. |
|
|
247 | - do not try to link against -lrt. |
|
|
248 | - use a separate configure script for IO::AIO (not the libeio one). |
|
|
249 | |
|
|
250 | 3.0 Sun May 11 00:57:14 CEST 2008 |
|
|
251 | - added bin/treescan to the distribution. |
|
|
252 | - switched to using libeio. |
|
|
253 | - LOTS OF INCOMPATIBLE CHANGES: |
|
|
254 | - remove signal functionality, it is not worth the effort. |
|
|
255 | - max_outstanding no longer returns the previous number of requests. |
|
|
256 | - poll_cb no longer returns number of requests. |
|
|
257 | |
|
|
258 | 2.62 Sat Apr 26 13:59:33 CEST 2008 |
|
|
259 | - port to solaris perls configured for old posix |
|
|
260 | (analysed by Jost Krieger). |
|
|
261 | - keep a reference to the perl filehandle object in aio_close, |
|
|
262 | so it doesn't get closed prematurely, leading to ugly races. |
|
|
263 | |
|
|
264 | 2.61 Wed Apr 16 18:45:02 CEST 2008 |
|
|
265 | - fix treescan output duplication and improve output ordering. |
|
|
266 | also display files given on the commandline. |
|
|
267 | - use a different algorithm for aio_close that is faster |
|
|
268 | and probably has even lower chances of blocking. |
|
|
269 | - do our own stack memory management for threads - linux |
|
|
270 | allocates outrageous amounts of VM (not so bad unless you |
|
|
271 | use mlockall...), which severely limits the number of threads |
|
|
272 | on 32-bit arches: stack size is the larger of PTHREAD_STACK_MIN |
|
|
273 | and 4096 * sizeof (long) (usually this is 16..64k). |
|
|
274 | |
|
|
275 | 2.6 Sun Mar 30 08:28:11 CEST 2008 |
|
|
276 | - added aio_sync. |
|
|
277 | - added aio_pathsync. |
|
|
278 | - fix prototypes of (void) functions. |
|
|
279 | |
|
|
280 | 2.51 Sat Oct 6 16:04:54 CEST 2007 |
|
|
281 | - perlio isn't generally threadsafe, so aio_close could not work reliably. |
|
|
282 | aio_close now tries a safe hack that might not be that asynchronous |
|
|
283 | (see the manpage for details). |
|
|
284 | - discard callback return values as to not grow the stack endlessly |
|
|
285 | when poll_cb handles many requests without returning. |
|
|
286 | - minor code cleanups. |
|
|
287 | |
|
|
288 | 2.5 Thu Oct 4 14:49:08 CEST 2007 |
|
|
289 | - replaced _fd2fh with faster xs code. |
|
|
290 | - aio_close will now try to do "the right thing" and thus might |
|
|
291 | work sensibly for the very first time. |
|
|
292 | |
|
|
293 | 2.41 Mon Sep 24 21:28:21 CEST 2007 |
|
|
294 | - after fork, invest some work to make sure that the poll_fileno |
|
|
295 | stays stable (by dup2'ing the new fd over the old one), to make |
|
|
296 | it easier for programs/libs that don't control their forking |
|
|
297 | behaviour and cannot recreate their watchers. |
|
|
298 | |
|
|
299 | 2.4 Sun Aug 5 18:44:22 CEST 2007 |
|
|
300 | - add aio_truncate, aio_chmod, aio_chown, aio_utime (linux |
|
|
301 | successfully demonstrated that you can block on futimes...). |
|
|
302 | - allow undef as fileoffset for aio_read/write and use read/write(2) |
|
|
303 | internally (useful for sockets or O_APPEND handles). |
|
|
304 | - allow undef for length in aio_write. |
|
|
305 | - negative dataoffsets work as expected now in aio_read/aio_write. |
|
|
306 | - use NV instead of UV for 32 bit perls and file offsets, as NVs |
|
|
307 | have a larger range then. |
|
|
308 | - shared code between BDB and IO::AIO. |
|
|
309 | - aio_busy was completely broken. now fixed. |
|
|
310 | - readahead emulation now returns something. |
|
|
311 | - correctly set errno to ENOSYS on unimplemented functions |
|
|
312 | (should never happen, though). |
|
|
313 | - large changes to make it partially compile and run on win32, |
|
|
314 | but win32 lacks too much functionality, and perl overrides way |
|
|
315 | too many functions with crashing versions. |
|
|
316 | |
|
|
317 | 2.33 Tue Jan 23 23:55:41 CET 2007 |
|
|
318 | - fix install path (Andreas J. Koenig). |
|
|
319 | |
|
|
320 | 2.32 Mon Jan 22 16:56:23 CET 2007 |
|
|
321 | - added aio_rmtree. |
|
|
322 | - wow, aio_mkdir was missing. |
|
|
323 | - aio_load did return undef on error, not -1. |
|
|
324 | - use prefixexp not prefix in autoconf.pm |
|
|
325 | (suggested by ... rt.cpan.org unreachable). |
|
|
326 | - avoid installing autoconf.pm. |
|
|
327 | |
|
|
328 | 2.31 Sat Jan 6 03:46:02 CET 2007 |
|
|
329 | - added aio_load. |
|
|
330 | |
|
|
331 | 2.3 Sat Dec 23 05:48:07 CET 2006 |
|
|
332 | - fix off-by-one bug in aio_read, causing memory corruption |
|
|
333 | or crashes. |
|
|
334 | |
|
|
335 | 2.21 Fri Dec 22 05:03:38 CET 2006 |
|
|
336 | - minor doc updates. |
|
|
337 | - minor cleanups. |
|
|
338 | - IO::AIO::poll returns request count. |
|
|
339 | - undocumented and unfinished async-signal-reporting. |
|
|
340 | |
|
|
341 | 2.2 Tue Oct 31 00:31:00 CET 2006 |
|
|
342 | - minor doc updates. |
|
|
343 | - added aio_readlink. |
|
|
344 | - properly zero-terminate aio_read buffer. |
|
|
345 | - fix aio_read/write with nonzero dataoffset. |
|
|
346 | - reduced size of aio request structure. |
|
|
347 | - better diagnostics when pathnames etc. are not byte-encoded; |
|
|
348 | do not leak request in that case, either. |
|
|
349 | |
|
|
350 | 2.1 Sun Oct 29 02:01:57 CET 2006 |
|
|
351 | - INCOMPATIBLE CHANGE: replace IO::AIO::poll_some by |
|
|
352 | IO::AIO::max_poll_reqs and IO::AIO::max_poll_time. |
|
|
353 | - fix a bug in aio_move where it would fail everytime |
|
|
354 | it would have to copy files manually. |
|
|
355 | - doc updates. |
|
|
356 | - start threads only on (very low) demand. |
|
|
357 | - end superfluous threads automatically after 10s idling. |
|
|
358 | - add IO::AIO::max_idle to control this. |
|
|
359 | - some tuning applied to random places. |
|
|
360 | - add aio_mknod. |
|
|
361 | |
|
|
362 | 2.0 Thu Oct 26 18:27:58 CEST 2006 |
|
|
363 | - minor incompatibility: max_outstanding semantics have changed. |
|
|
364 | - major rewrite, consider all functionality EXPERIMENTAL. |
|
|
365 | - aio requests can be cancelled. |
|
|
366 | - callbacks can be (re-)set later. |
|
|
367 | - aio requests can choose between 9 priorities. |
|
|
368 | - add aio_group: aio requests can be grouped |
|
|
369 | into composite requests. |
|
|
370 | - generator interface for groups. |
|
|
371 | - add IO::AIO::poll_some. |
|
|
372 | - major documentation improvements. |
|
|
373 | - very minor bugfixes. |
|
|
374 | - add aio_nop for dummy requests. |
|
|
375 | - add aio_busy mainly for benchmarking and debugging. |
|
|
376 | - use "fast" mutexes on linux. |
|
|
377 | - use dynamic (and larger) buffers instead of |
|
|
378 | putting them onto the stack. |
|
|
379 | - optimise x86 and amd64 a bit. |
|
|
380 | - better error checking when ENOMEM. |
|
|
381 | - hopefully fix mem and dirp leaks on fork. |
|
|
382 | - warn about broken perl malloc. |
|
|
383 | - compiles on cygwin (but pread is broken on cygwin |
|
|
384 | which is not detected by autoconf, so you have to |
|
|
385 | edit autoconf/config.h yourself to enable emulation). |
|
|
386 | |
|
|
387 | 1.8 Sat Jun 24 22:20:44 CEST 2006 |
|
|
388 | - add and/or document aio_rename, aio_link, aio_symlink and aio_move. |
|
|
389 | |
|
|
390 | 1.73 Wed Mar 1 22:49:32 CET 2006 |
|
|
391 | - codename "jost" |
|
|
392 | - AIX/Solaris(?) aren't being helpful again, hardcode a value |
|
|
393 | for NAME_MAX and drive with your eyes closed (reported by |
|
|
394 | wcooley@nakedape.cc). |
|
|
395 | |
|
|
396 | 1.72 Thu Feb 2 00:40:44 CET 2006 |
|
|
397 | - another minor bug in aio_scandir, again, the callback was called |
|
|
398 | twice when the directory can't be stat'ed. |
|
|
399 | |
|
|
400 | 1.71 Mon Dec 26 20:20:03 CET 2005 |
|
|
401 | - grr, another minor bug in aio_scandir, this time resulting |
|
|
402 | in a runtime error. |
|
|
403 | |
|
|
404 | 1.7 Mon Dec 26 19:29:48 CET 2005 |
|
|
405 | - aio_scandir errornously called callback twice in some cases. |
|
|
406 | - added AnyEvent example. |
|
|
407 | |
|
|
408 | 1.61 Wed Sep 7 19:40:42 CEST 2005 |
|
|
409 | - no longer include $Config{libs}, as distros include too much |
|
|
410 | garbage in there that is not installed on typical systems |
|
|
411 | (for example, debian links perl against -lgdbm and many more |
|
|
412 | libraries despite perl not needing it, slowing down startup and |
|
|
413 | wasting memory). |
|
|
414 | |
|
|
415 | 1.6 Tue Aug 30 17:44:44 CEST 2005 |
|
|
416 | - added aio_readdir, aio_scandir. |
|
|
417 | - added aio_sendfile, including sendfile emulation when sendfile |
|
|
418 | isn't available. Linux, FreeBSD and HP-UX might work (sendfilev |
|
|
419 | support is unavailable on my solaris 8 machine, but preliminary |
|
|
420 | code is there. What's lacking is configury stuff and testing...). |
|
|
421 | |
|
|
422 | 1.5 Sat Aug 20 02:32:19 CEST 2005 |
|
|
423 | - create the aio threads on demand only (good after forking). |
|
|
424 | - somebody nagged about C89 compatibility, so this release should |
|
|
425 | be C89 compatible, but no guarantees for future ones. |
|
|
426 | - abort when the configure script fails. |
|
|
427 | |
|
|
428 | 1.4 Wed Aug 17 08:07:27 CEST 2005 |
|
|
429 | - forgot to recreate the pipe after forking, this could cause |
|
|
430 | deadlocks. |
|
|
431 | |
|
|
432 | 1.3 Wed Aug 17 07:25:54 CEST 2005 |
|
|
433 | - properly propagate exceptions from callbacks, instead of silently |
|
|
434 | eating them. |
|
|
435 | - use a different fork algorithm that avoids recursive callback |
|
|
436 | invocations and reduces fork latency in busy processes. |
|
|
437 | - fix a bug where the buffer scalar in aio_read got assigned the wrong |
|
|
438 | length after reading. |
|
|
439 | - fix a bug where the child would process some outstanding requests |
|
|
440 | from the parent. |
|
|
441 | - make a copy of the callback scalar, to avoid some very uncommon |
|
|
442 | (but valid) usages where the callback scalar changes. |
|
|
443 | - the callback was never freed in aio_read/aio_write. |
|
|
444 | - aio_read/aio_write will now set the readonly flag on the data |
|
|
445 | scalar for better error reporting. |
|
|
446 | |
|
|
447 | 1.2 Wed Aug 17 01:22:58 CEST 2005 |
|
|
448 | - verified on cygwin, linux/amd64+ia32+alpha, solaris. |
|
|
449 | - use SvPVbyte for filenames now. You *need* to encode your strings to |
|
|
450 | the external filename encoding first. |
|
|
451 | - fix the bug where filehandles could leak (again). |
|
|
452 | - clarify freebsd situation: make it work and tell me how, or go away |
|
|
453 | with your underdocumented, broken and outdated OS. |
|
|
454 | - fork'ing should now be officially supported (where linux and |
|
|
455 | posix contradict each other, I followed posix). |
|
|
456 | - only call read() once per poll, not twice (speedup). |
|
|
457 | - new functions: aio_rmdir, aio_symlink. |
|
|
458 | - force callback arguments to be undef or a reference, for better |
|
|
459 | error catching. |
|
|
460 | |
|
|
461 | 1.1 Sun Aug 7 05:27:23 CEST 2005 |
|
|
462 | - added configure script to detect availability of some calls. |
|
|
463 | (imperfect, as we cannot detect things like -lrt due to missing |
|
|
464 | feedback yet). |
|
|
465 | - emulate fdatasync via fsync, pread/pwrite via unsafe read/write |
|
|
466 | and readahead via manual reading on platforms lacking those. |
|
|
467 | - ported t/03_errors.t+framework by Brad Fitzpatrick |
|
|
468 | from Linux::AIO. |
|
|
469 | - removed XOPEN_SOURCE because stupid solaris 9 doesn't |
|
|
470 | compile with it enabled. Probably breaks others. Oh well. |
|
|
471 | - try to be more careful with errno on non-threaded perls. |
|
|
472 | - cygwins perl insisted on a matching open mode when morphing |
|
|
473 | the fd to an fh. |
|
|
474 | - convert sv's to "byte" encoding in aio_read/aio_write. Might |
|
|
475 | do that for pathnames, too, in the future, so make sure you |
|
|
476 | properly encode your pathnames. |
|
|
477 | |
|
|
478 | 1.0 Fri Jul 22 10:43:30 CEST 2005 |
|
|
479 | - aio_open did not reliably deliver (open) filehandles. |
|
|
480 | - all aio_*-functions keep a reference to the filehandle so |
|
|
481 | it doesn't go away while the aio requests is working on it. |
|
|
482 | - disable warnings in AIO.pm. |
|
|
483 | |
|
|
484 | 0.9 Wed Jul 20 23:55:04 CEST 2005 |
|
|
485 | - allow recursive calls to poll_cb, use less locking calls, too. |
|
|
486 | - fix the Gtk2-example in the SYNOPSIS. |
|
|
487 | - use pread/pwrite not pread64/pwrite64. this was simply a leftover |
|
|
488 | from Linux::AIO. |
|
|
489 | (found by compiling on cygwin. Unfortunately, cygwin declares but |
|
|
490 | does not implement pread/pwrite). |
|
|
491 | - only include <sys/syscall.h> on linux. |
|
|
492 | |
|
|
493 | 0.5 Tue Jul 12 13:03:09 CEST 2005 |
|
|
494 | - removed #include <endian.h>, it's not portable, and we don't |
|
|
495 | need it anyway. |
|
|
496 | - link against -lrt, as it might contain goodies such as fdatasync, |
|
|
497 | and often aio_read, which we do not use yet, but it shouldn't hurt. |
|
|
498 | |
|
|
499 | 0.4 Mon Jul 11 05:28:25 CEST 2005 |
|
|
500 | - added IO::AIO::flush, IO::AIO::poll. |
|
|
501 | - make callback argument optional for all calls. |
|
|
502 | |
|
|
503 | 0.3 Mon Jul 11 01:42:37 CEST 2005 |
| 3 | - restructured manpage. |
504 | - restructured manpage. |
|
|
505 | - added SYNOPSIS with examples for Event, Glib, Tk. |
|
|
506 | - remove explicit context support so I don't have to maintain |
|
|
507 | it for threaded perls (i.e. it should work now :). |
| 4 | |
508 | |
| 5 | 0.2 Sun Jul 10 22:57:12 CEST 2005 |
509 | 0.2 Sun Jul 10 22:57:12 CEST 2005 |
| 6 | - return immediately from poll_wait if nreqs==0. |
510 | - return immediately from poll_wait if nreqs==0. |
| 7 | - get rid of the request pipe and use faster thread-thread |
511 | - get rid of the request pipe and use faster thread-thread |
| 8 | communications for most requests and responses. |
512 | communications for most requests and responses. |
