38 - new aio_slurp request.
39 - new IO::AIO::eventfd and timerfd* function.
40 - removed filesystem magic number table from aio_statvfs docs as
41 statvfs doesn't actually return this info at all (statfs does).
42 - add a bunch of (mostly linux-specific) constants for use in ioctls
43 (see aio_ioctl docs).
44 - treescan now has a proper manpage and useful --help output.
45 - new option --sync in treescan, to sync everything in a subtree.
46 - changed default for aio_msync flags to MSYNC_SYNC.
47 - document offset/length behaviour of mprotect/madvise.
48 - support linux's renameat2 (via aio_rename2).

58
594.34 Sun May 1 19:18:24 CEST 2016
60 - def0.h was not properly generated during previous release, causing
61 compile errors on various platforms.
62 - major/minor were accidentally switched (reported by Alexander Lishenyuk).
63 - removed duplicate definition of MAP_HUGETLB, that was found due to
64 a bug in Perl::Tidy (testcase by alaska332@gmail.com).
65 - added (untested!) aio_fcntl, aio_ioctl requests.
66 - (libeio) names set via prctl are truncated to 15 chars + nul, not 16,
67 as manpages-dev originally claimed.
68
694.33 Mon Jan 18 12:50:10 CET 2016
70 - add IO::AIO::pipe2 function.
71 - added support for FALLOC_FL_COLLAPSE_RANGE and FALLOC_FL_ZERO_RANGE
72 constants.
73 - added support for O_TMPFILE and O_PATH constants.
74 - added support for MAP_FIXED, MAP_GROWSDOWN,MAP_32BIT, MAP_HUGETLB, MAP_STACK

864.31 Tue Jun 3 03:29:27 CEST 2014
87 - work around more 5.20 bugs. backwards compatibility my ass.
88
894.3 Fri Apr 11 06:22:38 CEST 2014
90 - perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
91 without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
92 in 5.18. What's so attractive about giving a shit about backwards
93 compatibility - I will never understand.
94
954.2 Sat Jan 25 01:13:14 CET 2014
96 - aio_group could corrupt memory because it didn't restore
97 the stack after req_submit.
98 - be more careful on (e.g. permission) errors in bin/treescan.
99 - work around changes in ExtUtils::MakeMaker.
100 - (libeio) implement aio_realpath for win32.

109
1104.18 Thu Oct 11 07:01:26 CEST 2012
111 - fix unintended xthread_create by intentionalising it :)

1134.17 Thu Oct 11 05:19:47 CEST 2012
114 - rename aio_fallocate to aio_allocate, to match documentation.
115 - add list of linux fsid values to aio_statvfs docs.
116 - work around a bug in btrfs' FIEMAP ioctl implementation.
117 - work around AIX bug: statvfs.f_fsid is a struct, not unsigned long
118 as per unix spec.
119
1204.16 Tue Aug 14 05:39:03 CEST 2012
121 - aio_statvfs was wromgly marked for wd emulation, causing
122 it to malfunction for paths.
123 - fix a crash in aio_fiemap, when used on ranges without any
124 extents.
125 - work around linux kernel bug (at least in 3.2): kernel might
126 trash fiemap input arguments.
127 - work around linux kernel bug (at least in 3.2): kernel does not
128 set FIEMAP_EXTENT_LAST on last segment.
129 - work around linux kernel bug (at least in 3.2): kernel silently
130 truncates segment count if a file.
131 - make fh argument of IO::AIO::mmap optional, also add mmap/munmap
132 to quick overview.
133 - splice can corrupt data.
134 - (libeio) remove pread/pwrite emulation.
135 - do not grow mmaped scalars in aio_read.

138
1394.15 Tue Apr 10 06:59:00 CEST 2012
140 - always include linux/types.h for fiemap, for compatibility to
141 ancient systems (Paul Howarth).
142 - experimental support for IO::AIO::splice and ::tee (no aio_...).
143 - provide SEEK_HOLE and SEEK_DATA, if available.
144 - work around (again!) an immensely stupid bug in RHEL, defining
145 autoconf macros in linux system headers (analysed by Paul Howarth).
146
1474.14 Sat Apr 7 02:45:18 CEST 2012
148 - fix stat structure usage on windows, which caused bogus stat results.
149 - (libeio) make readahead emulation behave more like actual readahead by never failing.
150 - new request aio_seek.
151 - new request aio_fiemap.
152 - autogenerate the #ifdef/#define 0 blocks for symbols we export.
153
1544.12 Fri Dec 30 08:51:25 CET 2011
155 - realpath would return a random value if the name was too long,
156 instead of -1.
157 - port to c89.
158
1594.11 Mon Oct 10 00:24:11 CEST 2011
160 - libeio didn't compile on !linux (Paul Howarth).
161
1624.1 Sun Oct 9 10:24:11 CEST 2011
163 - IO::AIO did access uninitialised memory on unsuccessful stats.
164 - (libeio) added syncfs syscall wrapper.
165 - (libeio) set thread name on linux (ps -L/Hcx, top, gdb).
166 - (libeio) support multiple indepenent working directories.
167 - applied speling corrections by Nicholas Bamber.
168 - tune treescan #threads and #outstanding requests a bit.
169 - reduce the number of file descriptors in use at any one time
170 in treescan, to avoid running out of them (and using too much ram).
171 - take advantage of working directoriy abstractions
172 in aio_scandir and treescan.
173 - reduce compiled size by ~10% by not inlining some key functionality.
174 - added --progress switch to treescan.
175
1764.0 Mon Jul 18 05:01:10 CEST 2011
177 - INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
178 see FORK BEHAVIOUR in manpage for details.
179 - passes testsuite on win32 now and may actually work
180 (activestate 5.10.1 / MSVC6, YMMV).
181 - (libeio) fix a deadlock where a wakeup signal could be missed when
182 a timeout occured at the same time.
183 - (libeio) added realpath.
184 - (libeio) added fallocate.
185 - (libeio) disabling sendfile on darwin unfortunately broke the emulation.
186 - (libeio) do not acquire any locks when forking.
187 - (libeio) use fewer time() syscalls when waiting for new requests.
188
1893.93 Wed Jun 29 23:44:18 CEST 2011
190 - ECB.H WAS MISSING.
191
1923.92 Wed Jun 29 14:45:41 CEST 2011
193 - ecb.h was missing.
194
1953.91 Wed Jun 29 13:24:42 CEST 2011
196 - (libeio) work around a Linux (and likely FreeBSD and other
197 kernels) bug where sendfile would not transfer all the requested
198 bytes on large transfers, using a heuristic.
199 - buggy sendfile caused aio_move/copy to sometimes fail for big
200 files (fortunately it checks that the whole file has been
201 transferred...)
202 - use libecb for higher performance and higher portability.
203 - (libeio) disable sendfile on darwin, it's too broken.
204 - disable fork tests on !linux, as only linux supports mixing
205 pthread and fork in perl.
206 - document the fact that fork doesn't work anymore when using
207 this module, on anything !GNU/Linux.
208 - increase timeout in t/04_fork.t, as too many CPAN-tester setups
209 run on a 0.1MHz cpu. Or so.
210
2113.9 Fri May 27 02:43:47 CEST 2011
212 - (libeio) fix memory corruption in aio_readdirx for the flags
213 combination READDIR_STAT_ORDER | READDIR_DIRS_FIRST.
214 - add lots of newer POSIX and GNU/Linux-specific open
215 flags.
216
2173.8 Sun Mar 27 12:25:33 CEST 2011
218 - use nonstandard but maybe-working-on-bsd fork technique.
219 - support a max_idle value of 0.
220 - support setting of idle timeout value (IO::AIO::idle_timeout).
221
2223.72 Fri Feb 11 04:25:38 CET 2011
223 - use _POSIX_MEMLOCK_RANGE to detect mlock/munlock.
224 - aio_mknod always used a dev_t value of 0.
225 - new treescan option: --grep.
226 - add more S_IF macros, and major/minor/makedev "macros".
227
2283.71 Thu Dec 30 08:18:46 CET 2010
229 - the numerical result value passed to callbacks did not stringify
230 correctly, due to internal reuse and failure to reset the sv flags.
231 - actually test for posix_[mf]advise, as at least uClibc defines
232 _POSIX_ADVISORY_INFO without actually having any of the required
233 funcitonality. ugh.
234
2353.7 Mon Nov 1 23:00:34 CET 2010
236 - implement/add madvise, mmap, munmap, aio_mlockall, munlockall,
237 aio_mlock, munlock, msync and mtouch to @EXPORT_OK.
238 - document the sad state of affairs w.r.t. pthread on many bsds.
239 - do not enable mmap on systems without _POSIX_MAPPED_FILES
240 (openbsd 4.8).
241 - do not leak memory in IO::AIO::mmap when the scalar already
242 had string-data.
243 - add O_RDWR, O_APPEND and O_EXCL symbols and semi-document
244 them.
245 - cache the result IV, for a minor speedup in the common case.
246 - croak when an mmapped-scalar changes location, to detect
247 user-errors better.
248 - fix aio_readlink prototype.
249
2503.65 Wed Mar 31 02:45:05 CEST 2010
251 - actually use PATH_MAX instead of NAME_MAX for readlink, as to not
252 cut off long pathnames in aio_readlink (based on patch by
253 Rasmus Andersson).
254 - a double fork partially killed the event pipe (great testcase
255 by dormando). affects IO::AIO, BDB and Async::Interrupt.
256 - suck steve's dick and rename our symbols to avoid colliding
257 with nonstandard identifier spam on the broken os x pseudo-os.
258 affects IO::AIO and BDB.
259
2603.6 Mon Jan 11 00:43:39 CET 2010
261 - (libeio) more fixes for the freebsd/apple sendfile - broken by
262 manpage standards, but apparently correct accoridng to actual
263 kernel sources.
264 - add IO::AIO::mmap/munmap support.
265 - add IO::AIO::m(un)lockall support.
266 - clean up manpage.
267
2683.5 Thu Jan 7 21:25:04 CET 2010
269 - (liebio) fix freebsd sendfile (Vanilla Hsu).
270 - (libeio) also fix darwin sendfile that suffered from a similar bug.
271 - add aio_statvfs as interface to statvfs/fstatvfs.
272 - work around buggy symlink() on cygwin in the testsuite.
273 - wtf. freebsd-8.0 actually passes the testsuite! I knew
274 they could implement fork and semaphores one day! cheers!
275
2763.4 Sat Jan 2 15:13:04 CET 2010
277 - (libeio) max_poll_time was not properly converted to ticks.
278 - clarify cancel_subs description.
279 - IO::AIO::sendfile did not actually return the return value
280 from the sendfile call.
281 - implement aio_msync, aio_mtouch.
282 - (libeio) tentatively support darwin in sendfile.
283
2843.31 Thu Nov 12 02:14:29 CET 2009
285 - fix result status documentation of aio_copy, aio_move.
286 - speed up object creation considerably by avoiding
287 hash lookups.
288
2893.3 Wed Aug 5 13:52:58 CEST 2009
290 - use common::sense.
291 - use common schmorp.h header.
292 - allow integers (file descriptors) in addition to file handles.
293 - take advantage of linux' eventfd (but it seems slower on smp?).
294 - use poll not select on posix platforms.
295
2963.261 Wed Jul 1 10:11:51 CEST 2009
297 - more 0S X workarounds (patch by Tokuhiro Matsuno).
298
2993.26 Tue Jun 30 09:33:26 CEST 2009
300 - 0S X of course claims to be posix 2008 but lacks posix_fadvise.
301 try to work around this horribly broken OS in a somewhat hackish
302 way. might help other os's too.
303
3043.25 Sat Jun 27 05:18:26 CEST 2009
305 - added IO::AIO::fadvise and IO::AIO::sendfile.
306 - (libeio) replaced quicksort+insertion sort by a tuned radix
307 sort + insertion sort, resulting in comparable runtime (usually
308 faster) to the old version, but without any ill side effects on
309 degenerated (for quicksort) data.
310 - (libeio) correctly sort dirs by inodes if we have perfect type
311 knowledge and DIRS_FIRST is used.
312 - (libeio) internally the wrong DT_* constants were used, but no
313 known system has differing EIO_DT_*/DT_* values, so not an issue.
314 - removed a (harmless) assert that was left over on the code
315 but should not have been.
316 - use more correct types (change IO length from IV to VAL64,
317 which makes a difference on systems without 64 bit perls).
318
3193.23 Sat Jun 13 16:57:58 CEST 2009
320 - fix off-by-one bug in aio_readdir that was introduced in the
321 rushed 3.22 release.
322
3233.22 Sat Jun 13 15:32:40 CEST 2009
324 - speed up readdirx sort algorithm slightly.
325 - bin/treescan was missing from distro tarball.
326
3273.21 Fri Jun 12 18:45:53 CEST 2009
328 - new options --dirs and --files for treescan.
329 - install bin/treescan by default.
330 - (libeio) aio_readdir can now be cancelled while executing.
331 - fix a printf format string for 64 bit systems (could lead
332 to problems on big endian 64 bit systems).
333 - do not use qsort() but our own algorithm: glibc initialises
334 the whole locale and I/O subsystem inside qsort, causing
335 a stack overflow on 32 bit machines. The new sort uses much less
336 stack and is more than twice as fast in typical situations.
337
3383.2 Sun Jun 7 20:30:05 CEST 2009
339 - (libeio) pwrite emulation was even more flawed than intended and did
340 not restore the file offset.
341 - add aio_readdirx, which can return inode and filetype and sort
342 the names in various ways.
343 - unfortunately, utime, chmod, chown on an open file that has just
344 been written can easily block, which caused aio_copy to block the
345 process. no more!
346 - no longer rely on dst path in aio_copy when futime is available.
347
3483.19 Tue Apr 21 22:05:21 CEST 2009
349 - more perl 5.10 workarounds for aio_read and write.
350 - aio_write no longer modifies the sv (if possible).
351 - aio_read now works correctly with magic values.
352
3533.18 Sun Apr 19 21:17:32 CEST 2009
354 - better diagnostics when some aio_* functions get passed an illegal fh.
355 - try to avoid crashes due to incompatible 5.10 API changes. grmbl.
356
3573.17 Thu Nov 20 08:45:36 CET 2008
358 - (libeio) added aio_sync_file_range (untested).
359 - add aio_busy to @IO::AIO::AIO_REQ.
360
3613.16 Wed Oct 22 18:28:01 CEST 2008
362 - use SvREFCNT_inc instead of SvREFCNT_inc_NN in a non-speed critical
363 part to improve portability to perl 5.8 (reported by szymon).
364
3653.15 Mon Oct 13 00:39:55 CEST 2008
366 - automatic removal of feeders was broken.
367 - (libeio) use a more robust method to detect whether a feeder
368 has added something to the group or not.
369
3703.1 Thu Oct 2 13:34:40 CEST 2008
371 - pre-deref the passed callback object, for increased speed
372 and decreased memory usage.
373 - call on_next_submit callback even for aio_group - impact unknown,
374 but seems more correct.
375 - $req->cb now returns the original callback.
376 - (libeio) pass EIO_GROUP/aio_group requests through the queue without
377 requiring a thread switch.
378 - (libeio) status code of aio_futime and aio_utime was always passed 0.
379 - do some other ยต-optimisations.
380
3813.07 Sat Aug 2 16:06:13 CEST 2008
382 - do not include LIBS in autoconf tests.
383
3843.06 Tue Jul 15 12:41:32 CEST 2008
385 - move preadwritelock definition before it's first reference,
386 to make it compile again on broken platforms (they still exist)
387 or badly cofngiured perls (redhat...), reported by Rob Bloodgood.
388
3893.05 Thu Jun 19 23:23:52 CEST 2008
390 - work around perl overriding readdir etc. with thread-unsafe
391 (sic!) versions.
392
3933.04 Wed Jun 18 01:35:38 CEST 2008
394 - (libeio) fix eio_mknod, which confused it's arguments.
395 - (libeio) do not use readdir_r, as Ulrich Drepper pointed out that this
396 is stupid.
397 - (libeio) fix eio__readahead prototype, patch by Jost Krieger.
398 - (libeio) fix a bug that could potentially cause IO::AIO
399 not to get initialised properly.
400
4013.03 Thu May 29 05:33:30 CEST 2008
402 - (libeio) correctly call pthread_attr_destroy ().
403 - (libeio) work around broken bsd headers once more.
404 - reduce shared library size again by not including wrappers.
405 - max_outstanding could cause poll to enter a busy-waiting loop.
406 - document the new IO::AIO::poll_cb result value.
407
4083.02 Mon May 12 02:32:02 CEST 2008
409 - fix a memory leak on aio_readlink.
410 - bring back working fchmod.
411 - nop and busy now set result to 0.
412 - set errno to ENOMEM when allocation fails.
413
4143.01 Sun May 11 03:07:03 CEST 2008
415 - (libeio) make it compile on systems without readahead or readdir_r.
416 - (libeio) improve configure check for readahead availability.
417 - do not try to link against -lrt.
418 - use a separate configure script for IO::AIO (not the libeio one).
419
4203.0 Sun May 11 00:57:14 CEST 2008
421 - added bin/treescan to the distribution.
422 - switched to using libeio.
423 - LOTS OF INCOMPATIBLE CHANGES:
424 - remove signal functionality, it is not worth the effort.
425 - max_outstanding no longer returns the previous number of requests.
426 - poll_cb no longer returns number of requests.
427
4282.62 Sat Apr 26 13:59:33 CEST 2008
429 - port to solaris perls configured for old posix
430 (analysed by Jost Krieger).
431 - keep a reference to the perl filehandle object in aio_close,
432 so it doesn't get closed prematurely, leading to ugly races.
433
4342.61 Wed Apr 16 18:45:02 CEST 2008
435 - fix treescan output duplication and improve output ordering.
436 also display files given on the commandline.
437 - use a different algorithm for aio_close that is faster
438 and probably has even lower chances of blocking.
439 - do our own stack memory management for threads - linux
440 allocates outrageous amounts of VM (not so bad unless you
441 use mlockall...), which severely limits the number of threads
442 on 32-bit arches: stack size is the larger of PTHREAD_STACK_MIN
443 and 4096 * sizeof (long) (usually this is 16..64k).
444
4452.6 Sun Mar 30 08:28:11 CEST 2008
446 - added aio_sync.
447 - added aio_pathsync.
448 - fix prototypes of (void) functions.
449
4502.51 Sat Oct 6 16:04:54 CEST 2007
451 - perlio isn't generally threadsafe, so aio_close could not work reliably.
452 aio_close now tries a safe hack that might not be that asynchronous
453 (see the manpage for details).
454 - discard callback return values as to not grow the stack endlessly
455 when poll_cb handles many requests without returning.
456 - minor code cleanups.
457
4582.5 Thu Oct 4 14:49:08 CEST 2007
459 - replaced _fd2fh with faster xs code.
460 - aio_close will now try to do "the right thing" and thus might
461 work sensibly for the very first time.
462
4632.41 Mon Sep 24 21:28:21 CEST 2007
464 - after fork, invest some work to make sure that the poll_fileno
465 stays stable (by dup2'ing the new fd over the old one), to make
466 it easier for programs/libs that don't control their forking
467 behaviour and cannot recreate their watchers.
468
4692.4 Sun Aug 5 18:44:22 CEST 2007
470 - add aio_truncate, aio_chmod, aio_chown, aio_utime (linux
471 successfully demonstrated that you can block on futimes...).
472 - allow undef as fileoffset for aio_read/write and use read/write(2)
473 internally (useful for sockets or O_APPEND handles).
474 - allow undef for length in aio_write.
475 - negative dataoffsets work as expected now in aio_read/aio_write.
476 - use NV instead of UV for 32 bit perls and file offsets, as NVs
477 have a larger range then.
478 - shared code between BDB and IO::AIO.
479 - aio_busy was completely broken. now fixed.
480 - readahead emulation now returns something.
481 - correctly set errno to ENOSYS on unimplemented functions
482 (should never happen, though).
483 - large changes to make it partially compile and run on win32,
484 but win32 lacks too much functionality, and perl overrides way
485 too many functions with crashing versions.
486
4872.33 Tue Jan 23 23:55:41 CET 2007
488 - fix install path (Andreas J. Koenig).
489
4902.32 Mon Jan 22 16:56:23 CET 2007
491 - added aio_rmtree.
492 - wow, aio_mkdir was missing.
493 - aio_load did return undef on error, not -1.
494 - use prefixexp not prefix in autoconf.pm
495 (suggested by ... rt.cpan.org unreachable).
496 - avoid installing autoconf.pm.
497
4982.31 Sat Jan 6 03:46:02 CET 2007
499 - added aio_load.
500
5012.3 Sat Dec 23 05:48:07 CET 2006
502 - fix off-by-one bug in aio_read, causing memory corruption
503 or crashes.
504
5052.21 Fri Dec 22 05:03:38 CET 2006
506 - minor doc updates.
507 - minor cleanups.
508 - IO::AIO::poll returns request count.
509 - undocumented and unfinished async-signal-reporting.
510
5112.2 Tue Oct 31 00:31:00 CET 2006
512 - minor doc updates.
513 - added aio_readlink.
514 - properly zero-terminate aio_read buffer.
515 - fix aio_read/write with nonzero dataoffset.
516 - reduced size of aio request structure.
517 - better diagnostics when pathnames etc. are not byte-encoded;
518 do not leak request in that case, either.
519
5202.1 Sun Oct 29 02:01:57 CET 2006
521 - INCOMPATIBLE CHANGE: replace IO::AIO::poll_some by
522 IO::AIO::max_poll_reqs and IO::AIO::max_poll_time.
523 - fix a bug in aio_move where it would fail everytime
524 it would have to copy files manually.
525 - doc updates.
526 - start threads only on (very low) demand.
527 - end superfluous threads automatically after 10s idling.
528 - add IO::AIO::max_idle to control this.
529 - some tuning applied to random places.
530 - add aio_mknod.
531
5322.0 Thu Oct 26 18:27:58 CEST 2006
533 - minor incompatibility: max_outstanding semantics have changed.
534 - major rewrite, consider all functionality EXPERIMENTAL.
535 - aio requests can be cancelled.
536 - callbacks can be (re-)set later.
537 - aio requests can choose between 9 priorities.
538 - add aio_group: aio requests can be grouped
539 into composite requests.
540 - generator interface for groups.
541 - add IO::AIO::poll_some.
542 - major documentation improvements.
543 - very minor bugfixes.
544 - add aio_nop for dummy requests.
545 - add aio_busy mainly for benchmarking and debugging.
546 - use "fast" mutexes on linux.
547 - use dynamic (and larger) buffers instead of
548 putting them onto the stack.
549 - optimise x86 and amd64 a bit.
550 - better error checking when ENOMEM.
551 - hopefully fix mem and dirp leaks on fork.
552 - warn about broken perl malloc.
553 - compiles on cygwin (but pread is broken on cygwin
554 which is not detected by autoconf, so you have to
555 edit autoconf/config.h yourself to enable emulation).
556
5571.8 Sat Jun 24 22:20:44 CEST 2006
558 - add and/or document aio_rename, aio_link, aio_symlink and aio_move.
559
5601.73 Wed Mar 1 22:49:32 CET 2006
561 - codename "jost"
562 - AIX/Solaris(?) aren't being helpful again, hardcode a value
563 for NAME_MAX and drive with your eyes closed (reported by
564 wcooley@nakedape.cc).
565
5661.72 Thu Feb 2 00:40:44 CET 2006
567 - another minor bug in aio_scandir, again, the callback was called
568 twice when the directory can't be stat'ed.
569
5701.71 Mon Dec 26 20:20:03 CET 2005
571 - grr, another minor bug in aio_scandir, this time resulting
572 in a runtime error.
573
5741.7 Mon Dec 26 19:29:48 CET 2005
575 - aio_scandir errornously called callback twice in some cases.
576 - added AnyEvent example.
577
5781.61 Wed Sep 7 19:40:42 CEST 2005
579 - no longer include $Config{libs}, as distros include too much
580 garbage in there that is not installed on typical systems
581 (for example, debian links perl against -lgdbm and many more
582 libraries despite perl not needing it, slowing down startup and
583 wasting memory).
584
5851.6 Tue Aug 30 17:44:44 CEST 2005
586 - added aio_readdir, aio_scandir.
587 - added aio_sendfile, including sendfile emulation when sendfile
588 isn't available. Linux, FreeBSD and HP-UX might work (sendfilev
589 support is unavailable on my solaris 8 machine, but preliminary
590 code is there. What's lacking is configury stuff and testing...).
591
5921.5 Sat Aug 20 02:32:19 CEST 2005
593 - create the aio threads on demand only (good after forking).
594 - somebody nagged about C89 compatibility, so this release should
595 be C89 compatible, but no guarantees for future ones.
596 - abort when the configure script fails.
597
5981.4 Wed Aug 17 08:07:27 CEST 2005
599 - forgot to recreate the pipe after forking, this could cause
600 deadlocks.
601
6021.3 Wed Aug 17 07:25:54 CEST 2005
4 - properly propagate exceptions from callbacks, instead of silently 603 - properly propagate exceptions from callbacks, instead of silently
5 eating them. 604 eating them.
605 - use a different fork algorithm that avoids recursive callback
606 invocations and reduces fork latency in busy processes.
607 - fix a bug where the buffer scalar in aio_read got assigned the wrong
608 length after reading.
609 - fix a bug where the child would process some outstanding requests
610 from the parent.
611 - make a copy of the callback scalar, to avoid some very uncommon
612 (but valid) usages where the callback scalar changes.
613 - the callback was never freed in aio_read/aio_write.
614 - aio_read/aio_write will now set the readonly flag on the data
615 scalar for better error reporting.
6 616
71.2 Wed Aug 17 01:22:58 CEST 2005 6171.2 Wed Aug 17 01:22:58 CEST 2005
8 - verified on cygwin, linux/amd64+ia32+alpha, solaris. 618 - verified on cygwin, linux/amd64+ia32+alpha, solaris.
9 - use SvPVbyte for filenames now. You *need* to encode your strings to 619 - use SvPVbyte for filenames now. You *need* to encode your strings to
10 the external filename encoding first. 620 the external filename encoding first.
