9 9
10 - port to stableperl-5.22.0-1.001.
11
126.43 Thu Jun 4 15:38:14 CEST 2015
13 - use stability canary.
14 - update libecb.
15
166.42 Wed Feb 11 20:29:52 CET 2015
17 - Coro::SemaphoreSet->try did not actually work (analyzed by
18 SATO Kentaro).
19 - upgrade libecb to be C11 compliant.
20
216.41 Sat Sep 6 22:08:46 CEST 2014
22 - restore portability to perl 5.8.x.
23 - give new Coro's a valid GvHV(PL_hintgv) - this is slow and takes
24 up some memory, but fixes "use feature" and similar modules
25 when used inside a Coro.
26 - allow zero as argument to Coro::Channel to mean the same thing
27 as no argument. this works with older versions as well,
28 but wasn't legal until now.
29 - slightly better c header file detection.
30
316.39 Mon Jun 2 00:00:08 CEST 2014
32 - work around more incompatible changes in 5.20.
33
346.38 Sun Jun 1 21:54:23 CEST 2014
35 - check that perl slots actually have enough space to hold
36 interpreter variables.
37 - untested port to perl 5.19 (64 bit tmps indices) (reported
38 by Andreas König).
39 - croak when cancel is called without a thread context.
40
416.37 Tue Mar 4 13:27:33 CET 2014
42 - *sigh*, removed leftover debugging code from debugging a
43 perl bug, of all things.
44
456.36 Tue Mar 4 07:11:59 CET 2014
46 - semaphores would not clear the destroy hook when interrupted
47 by ->throw, causing segfaults or worse.
48 - ->throw on a thread waiting for a semaphore did not acquire
49 the semaphore, but also didn't wake up other waiters,
50 possibly causing a deadlock.
51 - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess
52 to report a full stacktrace, which should help find out
53 where the actual call is.
54 - "atomically" destroy data in slf_destroy, because it is
55 the right thing to do, just in case.
56 - disable ecb.h libm dependency, to compile on ancient systems
57 or under adverse conditions.
58
596.33 Mon Nov 18 11:26:27 CET 2013
60 - do not crash when freeing padlists with holes (in 5.18).
61 - tentative SVt_BIND 5.19 port/fix.
62
636.32 Tue Nov 5 15:35:35 CET 2013
64 - use a new algorithm to derive padlists for perl 5.18. The old
65 one could lead to 0-pointer accesses inside perl (reported
66 by Darin McBride).
67
686.31 Thu May 9 07:39:48 CEST 2013
69 - Coro::AIO requests would crash if the thread was ready'd
70 while the request was ongoing.
71
726.29 Wed May 8 02:55:18 CEST 2013
73 - when an on_destroy handler destructs the coro currently being
74 destructed a perl scalar could be accessed after being freed,
75 likely causing a crash.
76
776.28 Wed Mar 6 06:58:02 CET 2013
78 - clean remnants of existing __DIE__ and __WARN__ handlers so
79 they lose their magic and will not cause segfaults later
80 (testcase by Andrey Sagulin).
81 - improved Coro::State documentation a bit.
82 - Coro::Debug::command now flushes the output.
83 - add hack detection code for x32 abi, because the braindead slugs
84 who designed that made it look exactly like x86_64 without
85 providing proper compile time symbols to test for it. as a result,
86 this detection cannot work reliably.
87 - valgrind stack registering was broken.
88 - do not rely on Time::HiRes anymore in Coro::Debug.
89
906.23 Fri Dec 7 23:36:37 CET 2012
91 - use experimental fiber implementation on native windows
92 perls.
93 - use sizeof (void *) as multiplication factor for stack sizes,
94 to accomodate the totally braindamaged microsoft 64 bit "os".
95 - changed verifier host from win2k-ap510-32 to win7-sp516-32/64.
96 activeperl 5.16 crashes when PerlIO_define_layer is called due
97 to some bug in the perl dll, strawberry perl at least passes
98 the testsuite.
99 - implement Coro::Handle->peeraddr/host/port, for slightly
100 improved compatibility with LWP.
101 - implement 5.17 compatibility by almost blindly applying a
102 good-looking patch by Father Chrysostomos.
103 - move stack management functions into libcoro 3.
104 - libcoro version 3 "released".
105 - support magic values as timed_io_once args.
106 - recommend AnyEvent 7+ or EV 4+, also require EV
107 version 4 or newer for Coro::EV.
108
1096.10 Tue Oct 9 01:14:27 CEST 2012
110 - updated ecb.h, it had a typo that caused it to not compile on many
111 big endian systems (reported by many people).
112 - disable memory fences in ecb.h to improve portability.
113
1146.09 Sat Oct 6 23:25:02 CEST 2012
115 - Coro::EV I/O watchers were not interruptible by exceptions
116 (Coro::State::throw) (testcase by sten).
117 - ->throw now puts threads into the ready queue, as this seems to
118 be expected by existing code, and code that doesn't cope with spurious
119 wakeups needs fixing anyway.
120 - use fd -1 in mmap.
121 - cast I32 to int in error message printf.
122 - warn about broken so-called "hardened" kernels.
123
1246.08 Fri Apr 13 12:05:47 CEST 2012
125 - be more aggressive about exiting like perl does - formerly,
126 exiting from the non-main thread would not execute END blocks.
127
1286.07 Fri Nov 11 21:21:48 CET 2011
129 - work around a bug in PerlIO (setting $SIG{__WARN__} to a PVCV).
130 - update ecb.h.
131
1326.06 Mon Aug 8 23:59:48 CEST 2011
133 - cygwin unfortunately patches the stack at runtime, so we use the pthreads
134 backend, which is an order of magnitude slower. unfortunately, cygwins
135 pthread implementation isn't very complete either, so allocate the stack
136 twice just to be sure.
137 (note: cygwin also enables mymalloc, which is NOT THREADSAFE ON WINDOWS,
138 in its ithreaded perl - best recompile cygwin and use the 'w'indows
139 backend for much better performance. also disable ithreads for
140 even better performance...).
141
1426.05 Thu Aug 4 21:36:36 CEST 2011
143 - blush, condvar values would not be propagated from send to recv anymore
144 (reported by Chip Salzenberg).
145 - use exponential increase for the readline buffer length in
146 Coro::Handle. also reduce initial allocation to 1020 from 4096 bytes.
147
1486.04 Wed Aug 3 17:15:45 CEST 2011
149 - use even more efficient and more compatible condvars for
150 compatibility to AnyEvent 6.x :)
151 - more inconsequential ecb.h updates.
152
1536.03 Wed Aug 3 11:41:30 CEST 2011
154 - change how Coro patches AnyEvent condvars for compatibility to
155 AnyEvent 6.x.
156 - update ecb.h, to no longer include <pthread.h> in case WinNT.h
157 hasn't been included.
158
1596.02 Wed Jul 13 04:35:19 CEST 2011
160 - "improve portability to Gentoo" - gentoo manages to put perl variables
161 in memory areas that are farther than 2gb apart, which the jit couldn't
162 handle and barfed. now it's just a bit slower on gentoo and similar
163 systems.
164
1656.01 Sun Jul 3 12:31:14 CEST 2011
166 - workarounds are good, but the test for whether pthreads are used
167 was not good. this one should be better.
168 - check differently whether gcc generates cfi instructions itself.
169
1706.0 Wed Jun 29 19:43:35 CEST 2011
171 - INCOMPATIBLE CHANGE: unreferenced coro objects will now be
172 destroyed and cleaned up automatically (e.g. async { schedule }).
173 - implement a JIT compiler for part of the thread switch code,
174 which gives a 50% speed improvement on threaded perls, and
175 about 4% on non-threaded perls (so threaded perls now finally
176 reach about half the speed of non-threaded perls).
177 - slightly modernise Coro::Intro, add section about rouse functions.
178 - avoid DEFSV and ERRSV, giving another 10% improvement
179 in thread switching.
180 - Coro::State->is_destroyed is now called is_zombie.
181 - implement a Coro->safe_cancel method that might fail, but
182 cancels in a "safer" way if it succeeds.
183 - add preliminary support for DEBUGGING perls.
184 - get rid of two hash-accesses when initialising a new Coro - this
185 speeds up coro creation by almost a factor of two.
186 - croak when a coro that is being cancelled tries to block
187 (e.g. while executing a guard block), instead of crashing or
188 deadlocking.
189 - use a more robust and also faster method to identify Coro::State
190 objects - speeds up everything a bit.
191 - implement Coro->cancel in XS for a 20% speed improvement, and to
192 be able to implement mutual cancellation.
193 - speed up context switches by a percent or two by more efficiently
194 allocating context stack entries.
195 - implement Coro->join and Coro->on_destroy in XS for a speedup and
196 a reduction in memory use.
197 - cancelling a coro while it itself is cancelling another coro is
198 now supported and working, instead of triggering an assertion.
199 - be a bit more crash-resistant when calling (buggy) on_destroy
200 callbacks (best effort).
201 - move on_destroy into the slf_frame, to allow extension slf
202 functions to have destructors.
203 - get rid if coro refcounting - simply crash in other interpreter
204 threads by nulling the pointers on clone.
205 - simplify warn/die hook handling when loading Coro - the convoluted
206 logic seems to be no longer neccessary.
207 - use libecb instead of our own home-grown gcc hacks.
208 - document alternatives to Coro::LWP. Please use them :)
209 - work around another mindless idiotic NEEDLESS bug in openbsd/mirbsds
210 sigaltstack. Really. wine suffers from it, erlang suffers from it,
211 and it's known since at least 2006.
212
2135.372 Wed Feb 23 06:14:30 CET 2011
214 - apparently mingw doesn't provide a working gettimeofday, try to
215 work around that by relying on Time::HiRes (indirectly brought to
216 my attention by Max Maischein).
217 - fix some portability issues when Time::HiRes was used.
218
2195.371 Mon Feb 21 14:36:08 CET 2011
220 - backport to windows process emulation code again.
221
2225.37 Sat Feb 19 07:49:44 CET 2011
223 - add a big "Coro thread life cycle" section to "man Coro".
224 - try a tentative workaround against the breakage that 5.13 has
225 introduced without depreciation period. sigh.
226 - no longer use Time::HiRes if gettimeofday is available, which
227 saves quite a lot of memory.
228
2295.36 Sun Feb 13 05:33:41 CET 2011
230 - automatically load Coro::Channel, Coro::RWLock, Coro::Semaphore,
231 Coro::SemaphoreSet, Coro::Signal and Coro::Specific on first "new"
232 method call.
233 - undocument Coro::Timer::sleep and obsolete whole module.
234 - optimise Coro::Timer::timeout memory and cpu usage.
235 - slightly updated Coro::Intro for recent changes.
236 - do not initialise PL_dirty anymore.
237
2385.25 Thu Nov 11 01:08:39 CET 2010
239 - try a different approach on netbsd - netbsd 5 finally has marginally
240 working pthreads, but still broken ucontext/sigaltstack.
241 - openbsd 4.8 finally got their act together, Coro works out of the box
242 with asm, setjmp and pthreads (no change, just informational).
243
2445.24 Sat Oct 23 11:27:12 CEST 2010
245 - port to the EV 4.0 API.
246 - work around bugs in mingw32, making strawberry perl work
247 out of the box.
248 - correctly modify Coro::AIO function prototypes
249 so that they reflect the "no optional parameters" rule.
250 - "ported" libcoro to C++.
251
2525.23 Mon May 17 18:50:42 CEST 2010
253 - be more resistant to ordering changes when initialising
254 Coro::AnyEvent, Coro::EV and Coro::Event (reported by Matthias
255 Waldorf).
256 - document that perl 5.12 deliberately removed support for cloning.
257
2585.22 Wed Apr 14 03:55:35 CEST 2010
259 - correctly return udnef on errors in Coro::Handle::read/write
260 (testcase by Marc Mims).
261 - convert Coro::Util into a "perl compatibility wrapper" - the functions
262 are less useful now, but are drop-in replacements for existing
263 functions, listing better alternatives in the documentation. This also
264 fixes a bug in Coro::LWP which naively substituted Socket::inet_aton
265 with Coro::Util::inet_aton.
266 - do not override $Coro::idle unconditionally in Coro.pm, as other
267 modules could have provided their own idle coro already
268 (for exmaple, Coro::AnyEvent).
269 - fix Coro::Util::gethost* functions.
270 - Coro::Timer corretcly exports it's symbols (reported by Hideki Yamamura).
271
2725.21 Wed Dec 16 07:19:51 CET 2009
273 - automatically load Coro::AnyEvent when AnyEvent and Coro are used
274 together.
275 - add some examples on how to combine other event loops with Coro in
276 Coro::AnyEvent, and how to run it (and not to block). Seems to be
277 the most common source of confusion.
278 - try to catch people naively blocking in an event callback.
279 - work around the perl filehandle bug issue in conjunction with
280 older common::sense (as indirectly pointed out by ZSystem).
281 - clarify the "not from signal handlers" section.
282
2835.2 Sun Oct 4 14:54:24 CEST 2009
284 - Coro::Storable destroyed the prototypes of the functions it wrapped.
285 - export rouse_cb and rouse_wait by default now.
286 - fix various prototype mismatches in Coro::AnyEvent and Coro::Handle.
287 - new method $state->swap_sv.
288 - added section on "windows process emulation" to the manpage,
289 after a not-so-fruitful (nor-friendly) "discussion" with chip
290 salzenberg (discussion implies arguments, but his only arguments
291 were ad-hominems, one wonders why he started it in the first
292 place). I hope this explains it well enough for him to understand,
293 and maybe well enough for others to understand.
294 - use common::sense everywhere now.
295 - idle callbacks are no longer supported, use idle coros instead.
296 - print a thread listing when a deadlock is detected.
297
2985.17 Sat Aug 22 23:09:31 CEST 2009
299 - work around a bug in the perl debugger causing crashes
300 when running under the debugger by marking _pool_handler as nodebug.
301 - speed up Coro::async considerably.
302 - try some hacks to get netbsd to work "more often" - their broken
303 setjmp/longjmp, ucontext *and* phtreads are really hard on Coro.
304 - convert Coro to AE 5.0 API.
305
3065.162 Tue Jul 28 04:04:03 CEST 2009
307 - perl 5.8.2 is now minimum requirement.
308 - skip t/19_handle.t on broken windows perls.
309
3105.161 Wed Jul 22 04:47:38 CEST 2009
311 - Coro::AnyEvent::poll could have a different prototype when EV was
312 used as backend (analyzed by Tatsuhiko Miyagawa).
313 - Coro::AnyEvent errornously initialised the event loop when loaded,
314 not on demand.
315 - try to workaround rare */t/01_unblock.t failures.
316
3175.16 Tue Jul 21 01:44:37 CEST 2009
318 - Coro::AnyEvent failed to hook into the event loop
319 when no threads had been readied between detecting
320 the event loop and actually running it.
321 - considerably speed up Coro::Select by taking avdantage
322 of AnyEvent > 4.8 and some other optimisations.
323 - implement paragraph readline mode in Coro::Handle
324 (based on patches by Zsbán Ambrus).
325 - replace WSAEINPROGRESS by WSAEWOULDBLOCK (reported
326 and analyzed by Yasuhiro MATSUMOTO).
327 - clarified libcoro license and copyright.
328 - someone stole my EXTRA_META!!!
329 - implement Coro::Select::patch_pp_sselect and it's brother,
330 for hardcode select overriding.
331
3325.151 Mon Jul 6 05:41:57 CEST 2009
333 - backport to windows process emulation code again (patch by
334 Yasuhiro MATSUMOTO).
335 - slightly update Coro::MakeMaker.
336
3375.15 Tue Jun 30 10:28:06 CEST 2009
338 - deprecate Coro::Socket, document how to get ipv6 support via
339 AnyEvent::Socket instead.
340 - implement signal->wait ($cb) interface, similar to semaphores.
341 - work around SvOK not supporting getmagic, so we have to getmagic
342 to test for undef :/ (reported by Matthias Waldorf).
343 - load Coro::AnyEvent in all modules using AnyEvent.
344 - work around perl corrupting our internal data structures,
345 reported by Tokuhiro Matsuno.
346 - enable per-coroutine real and cpu time gathering
347 (Coro::State::enable_times).
348
3495.14 Wed Jun 24 01:37:48 CEST 2009
350 - provide explicit functions to "cede" to the event loop in Coro::AnyEvent,
351 as this seems to have been a difficult concept (poll, sleep, idle,
352 idle_upto).
353 - add Coro::AnyEvent::readable/writable functions.
354 - clarify Coro::EV/Event/AnyEvent manpages.
355 - free per-thread global scalars in the thread calling ->cancel, to
356 avoid crashes when $_, $@ etc., are magical but some of those
357 had already been freed.
358 - "unexperimentalise" the callback interface for Coro::Semaphore.
10 - speed up ready queue management/context switching by using a linked 359 - speed up ready queue management/context switching by using a linked
11 list instead of an array (~5-10%). 360 list instead of an array (~5-10%).
12 - implement "watch" command in Coro::Debug shells. 361 - implement "watch" command in Coro::Debug shells.
362 - for fun, implement time-slicing as an example in the manpage.
363 - if AnyEvent detects EV or Event, but we don't have Coro::EV or
364 Coro::Event, use the normal AnyEvent handling instead of dieing
365 (the same is true for Coro::Handle).
366 - properly document Coro::EV::timed_io_once.
367 - avoid unneccessary ->cancel calls in Coro::Handle.
368 - maybe make it work on mingw32 with win32 backend
369 (based on patch by Yasuhiro Matsumoto).
