11 - restore portability to perl 5.8.x.
12 - give new Coro's a valid GvHV(PL_hintgv) - this is slow and takes
13 up some memory, but fixes "use feature" and similar modules
14 when used inside a Coro.
15 - allow zero as argument to Coro::Channel to mean the same thing
16 as no argument. this works with older versions as well,
17 but wasn't legal until now.
18 - slightly better c header file detection.
19
206.39 Mon Jun 2 00:00:08 CEST 2014
21 - work around more incompatible changes in 5.20.
22
236.38 Sun Jun 1 21:54:23 CEST 2014
24 - check that perl slots actually have enough space to hold
25 interpreter variables.
26 - untested port to perl 5.19 (64 bit tmps indices) (reported
27 by Andreas König).
28 - croak when cancel is called without a thread context.
29
306.37 Tue Mar 4 13:27:33 CET 2014
31 - *sigh*, removed leftover debugging code from debugging a
32 perl bug, of all things.
33
346.36 Tue Mar 4 07:11:59 CET 2014
35 - semaphores would not clear the destroy hook when interrupted
36 by ->throw, causing segfaults or worse.
37 - ->throw on a thread waiting for a semaphore did not acquire
38 the semaphore, but also didn't wake up other waiters,
39 possibly causing a deadlock.
40 - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess
41 to report a full stacktrace, which should help find out
42 where the actual call is.
43 - "atomically" destroy data in slf_destroy, because it is
44 the right thing to do, just in case.
45 - disable ecb.h libm dependency, to compile on ancient systems
46 or under adverse conditions.
47
486.33 Mon Nov 18 11:26:27 CET 2013
49 - do not crash when freeing padlists with holes (in 5.18).
50 - tentative SVt_BIND 5.19 port/fix.
51
526.32 Tue Nov 5 15:35:35 CET 2013
53 - use a new algorithm to derive padlists for perl 5.18. The old
54 one could lead to 0-pointer accesses inside perl (reported
55 by Darin McBride).
56
576.31 Thu May 9 07:39:48 CEST 2013
58 - Coro::AIO requests would crash if the thread was ready'd
59 while the request was ongoing.
60
616.29 Wed May 8 02:55:18 CEST 2013
62 - when an on_destroy handler destructs the coro currently being
63 destructed a perl scalar could be accessed after being freed,
64 likely causing a crash.
65
666.28 Wed Mar 6 06:58:02 CET 2013
67 - clean remnants of existing __DIE__ and __WARN__ handlers so
68 they lose their magic and will not cause segfaults later
69 (testcase by Andrey Sagulin).
70 - improved Coro::State documentation a bit.
71 - Coro::Debug::command now flushes the output.
72 - add hack detection code for x32 abi, because the braindead slugs
73 who designed that made it look exactly like x86_64 without
74 providing proper compile time symbols to test for it. as a result,
75 this detection cannot work reliably.
76 - valgrind stack registering was broken.
77 - do not rely on Time::HiRes anymore in Coro::Debug.
78
796.23 Fri Dec 7 23:36:37 CET 2012
80 - use experimental fiber implementation on native windows
81 perls.
82 - use sizeof (void *) as multiplication factor for stack sizes,
83 to accomodate the totally braindamaged microsoft 64 bit "os".
84 - changed verifier host from win2k-ap510-32 to win7-sp516-32/64.
85 activeperl 5.16 crashes when PerlIO_define_layer is called due
86 to some bug in the perl dll, strawberry perl at least passes
87 the testsuite.
88 - implement Coro::Handle->peeraddr/host/port, for slightly
89 improved compatibility with LWP.
90 - implement 5.17 compatibility by almost blindly applying a
91 good-looking patch by Father Chrysostomos.
92 - move stack management functions into libcoro 3.
93 - libcoro version 3 "released".
94 - support magic values as timed_io_once args.
95 - recommend AnyEvent 7+ or EV 4+, also require EV
96 version 4 or newer for Coro::EV.
97
986.10 Tue Oct 9 01:14:27 CEST 2012
99 - updated ecb.h, it had a typo that caused it to not compile on many
100 big endian systems (reported by many people).
101 - disable memory fences in ecb.h to improve portability.
102
1036.09 Sat Oct 6 23:25:02 CEST 2012
104 - Coro::EV I/O watchers were not interruptible by exceptions
105 (Coro::State::throw) (testcase by sten).
106 - ->throw now puts threads into the ready queue, as this seems to
107 be expected by existing code, and code that doesn't cope with spurious
108 wakeups needs fixing anyway.
109 - use fd -1 in mmap.
110 - cast I32 to int in error message printf.
111 - warn about broken so-called "hardened" kernels.
112
1136.08 Fri Apr 13 12:05:47 CEST 2012
114 - be more aggressive about exiting like perl does - formerly,
115 exiting from the non-main thread would not execute END blocks.
116
1176.07 Fri Nov 11 21:21:48 CET 2011
118 - work around a bug in PerlIO (setting $SIG{__WARN__} to a PVCV).
119 - update ecb.h.
120
1216.06 Mon Aug 8 23:59:48 CEST 2011
122 - cygwin unfortunately patches the stack at runtime, so we use the pthreads
123 backend, which is an order of magnitude slower. unfortunately, cygwins
124 pthread implementation isn't very complete either, so allocate the stack
125 twice just to be sure.
126 (note: cygwin also enables mymalloc, which is NOT THREADSAFE ON WINDOWS,
127 in its ithreaded perl - best recompile cygwin and use the 'w'indows
128 backend for much better performance. also disable ithreads for
129 even better performance...).
130
1316.05 Thu Aug 4 21:36:36 CEST 2011
132 - blush, condvar values would not be propagated from send to recv anymore
133 (reported by Chip Salzenberg).
134 - use exponential increase for the readline buffer length in
135 Coro::Handle. also reduce initial allocation to 1020 from 4096 bytes.
136
1376.04 Wed Aug 3 17:15:45 CEST 2011
138 - use even more efficient and more compatible condvars for
139 compatibility to AnyEvent 6.x :)
140 - more inconsequential ecb.h updates.
141
1426.03 Wed Aug 3 11:41:30 CEST 2011
143 - change how Coro patches AnyEvent condvars for compatibility to
144 AnyEvent 6.x.
145 - update ecb.h, to no longer include <pthread.h> in case WinNT.h
146 hasn't been included.
147
1486.02 Wed Jul 13 04:35:19 CEST 2011
149 - "improve portability to Gentoo" - gentoo manages to put perl variables
150 in memory areas that are farther than 2gb apart, which the jit couldn't
151 handle and barfed. now it's just a bit slower on gentoo and similar
152 systems.
153
1546.01 Sun Jul 3 12:31:14 CEST 2011
155 - workarounds are good, but the test for whether pthreads are used
156 was not good. this one should be better.
157 - check differently whether gcc generates cfi instructions itself.
158
1596.0 Wed Jun 29 19:43:35 CEST 2011
160 - INCOMPATIBLE CHANGE: unreferenced coro objects will now be
161 destroyed and cleaned up automatically (e.g. async { schedule }).
162 - implement a JIT compiler for part of the thread switch code,
163 which gives a 50% speed improvement on threaded perls, and
164 about 4% on non-threaded perls (so threaded perls now finally
165 reach about half the speed of non-threaded perls).
166 - slightly modernise Coro::Intro, add section about rouse functions.
167 - avoid DEFSV and ERRSV, giving another 10% improvement
168 in thread switching.
169 - Coro::State->is_destroyed is now called is_zombie.
170 - implement a Coro->safe_cancel method that might fail, but
171 cancels in a "safer" way if it succeeds.
172 - add preliminary support for DEBUGGING perls.
173 - get rid of two hash-accesses when initialising a new Coro - this
174 speeds up coro creation by almost a factor of two.
175 - croak when a coro that is being cancelled tries to block
176 (e.g. while executing a guard block), instead of crashing or
177 deadlocking.
178 - use a more robust and also faster method to identify Coro::State
179 objects - speeds up everything a bit.
180 - implement Coro->cancel in XS for a 20% speed improvement, and to
181 be able to implement mutual cancellation.
182 - speed up context switches by a percent or two by more efficiently
183 allocating context stack entries.
184 - implement Coro->join and Coro->on_destroy in XS for a speedup and
185 a reduction in memory use.
186 - cancelling a coro while it itself is cancelling another coro is
187 now supported and working, instead of triggering an assertion.
188 - be a bit more crash-resistant when calling (buggy) on_destroy
189 callbacks (best effort).
190 - move on_destroy into the slf_frame, to allow extension slf
191 functions to have destructors.
192 - get rid if coro refcounting - simply crash in other interpreter
193 threads by nulling the pointers on clone.
194 - simplify warn/die hook handling when loading Coro - the convoluted
195 logic seems to be no longer neccessary.
196 - use libecb instead of our own home-grown gcc hacks.
197 - document alternatives to Coro::LWP. Please use them :)
198 - work around another mindless idiotic NEEDLESS bug in openbsd/mirbsds
199 sigaltstack. Really. wine suffers from it, erlang suffers from it,
200 and it's known since at least 2006.
201
2025.372 Wed Feb 23 06:14:30 CET 2011
203 - apparently mingw doesn't provide a working gettimeofday, try to
204 work around that by relying on Time::HiRes (indirectly brought to
205 my attention by Max Maischein).
206 - fix some portability issues when Time::HiRes was used.
207
2085.371 Mon Feb 21 14:36:08 CET 2011
209 - backport to windows process emulation code again.
210
2115.37 Sat Feb 19 07:49:44 CET 2011
212 - add a big "Coro thread life cycle" section to "man Coro".
213 - try a tentative workaround against the breakage that 5.13 has
214 introduced without depreciation period. sigh.
215 - no longer use Time::HiRes if gettimeofday is available, which
216 saves quite a lot of memory.
217
2185.36 Sun Feb 13 05:33:41 CET 2011
219 - automatically load Coro::Channel, Coro::RWLock, Coro::Semaphore,
220 Coro::SemaphoreSet, Coro::Signal and Coro::Specific on first "new"
221 method call.
222 - undocument Coro::Timer::sleep and obsolete whole module.
223 - optimise Coro::Timer::timeout memory and cpu usage.
224 - slightly updated Coro::Intro for recent changes.
225 - do not initialise PL_dirty anymore.
226
2275.25 Thu Nov 11 01:08:39 CET 2010
228 - try a different approach on netbsd - netbsd 5 finally has marginally
229 working pthreads, but still broken ucontext/sigaltstack.
230 - openbsd 4.8 finally got their act together, Coro works out of the box
231 with asm, setjmp and pthreads (no change, just informational).
232
2335.24 Sat Oct 23 11:27:12 CEST 2010
234 - port to the EV 4.0 API.
235 - work around bugs in mingw32, making strawberry perl work
236 out of the box.
237 - correctly modify Coro::AIO function prototypes
238 so that they reflect the "no optional parameters" rule.
239 - "ported" libcoro to C++.
240
2415.23 Mon May 17 18:50:42 CEST 2010
242 - be more resistant to ordering changes when initialising
243 Coro::AnyEvent, Coro::EV and Coro::Event (reported by Matthias
244 Waldorf).
245 - document that perl 5.12 deliberately removed support for cloning.
246
2475.22 Wed Apr 14 03:55:35 CEST 2010
248 - correctly return udnef on errors in Coro::Handle::read/write
249 (testcase by Marc Mims).
250 - convert Coro::Util into a "perl compatibility wrapper" - the functions
251 are less useful now, but are drop-in replacements for existing
252 functions, listing better alternatives in the documentation. This also
253 fixes a bug in Coro::LWP which naively substituted Socket::inet_aton
254 with Coro::Util::inet_aton.
255 - do not override $Coro::idle unconditionally in Coro.pm, as other
256 modules could have provided their own idle coro already
257 (for exmaple, Coro::AnyEvent).
258 - fix Coro::Util::gethost* functions.
259 - Coro::Timer corretcly exports it's symbols (reported by Hideki Yamamura).
260
2615.21 Wed Dec 16 07:19:51 CET 2009
262 - automatically load Coro::AnyEvent when AnyEvent and Coro are used
263 together.
264 - add some examples on how to combine other event loops with Coro in
265 Coro::AnyEvent, and how to run it (and not to block). Seems to be
266 the most common source of confusion.
267 - try to catch people naively blocking in an event callback.
268 - work around the perl filehandle bug issue in conjunction with
269 older common::sense (as indirectly pointed out by ZSystem).
270 - clarify the "not from signal handlers" section.
271
2725.2 Sun Oct 4 14:54:24 CEST 2009
273 - Coro::Storable destroyed the prototypes of the functions it wrapped.
274 - export rouse_cb and rouse_wait by default now.
275 - fix various prototype mismatches in Coro::AnyEvent and Coro::Handle.
276 - new method $state->swap_sv.
277 - added section on "windows process emulation" to the manpage,
278 after a not-so-fruitful (nor-friendly) "discussion" with chip
279 salzenberg (discussion implies arguments, but his only arguments
280 were ad-hominems, one wonders why he started it in the first
281 place). I hope this explains it well enough for him to understand,
282 and maybe well enough for others to understand.
283 - use common::sense everywhere now.
284 - idle callbacks are no longer supported, use idle coros instead.
285 - print a thread listing when a deadlock is detected.
286
2875.17 Sat Aug 22 23:09:31 CEST 2009
288 - work around a bug in the perl debugger causing crashes
289 when running under the debugger by marking _pool_handler as nodebug.
290 - speed up Coro::async considerably.
291 - try some hacks to get netbsd to work "more often" - their broken
292 setjmp/longjmp, ucontext *and* phtreads are really hard on Coro.
293 - convert Coro to AE 5.0 API.
294
2955.162 Tue Jul 28 04:04:03 CEST 2009
296 - perl 5.8.2 is now minimum requirement.
297 - skip t/19_handle.t on broken windows perls.
298
2995.161 Wed Jul 22 04:47:38 CEST 2009
300 - Coro::AnyEvent::poll could have a different prototype when EV was
301 used as backend (analyzed by Tatsuhiko Miyagawa).
302 - Coro::AnyEvent errornously initialised the event loop when loaded,
303 not on demand.
304 - try to workaround rare */t/01_unblock.t failures.
305
3065.16 Tue Jul 21 01:44:37 CEST 2009
307 - Coro::AnyEvent failed to hook into the event loop
308 when no threads had been readied between detecting
309 the event loop and actually running it.
310 - considerably speed up Coro::Select by taking avdantage
311 of AnyEvent > 4.8 and some other optimisations.
312 - implement paragraph readline mode in Coro::Handle
313 (based on patches by Zsbán Ambrus).
314 - replace WSAEINPROGRESS by WSAEWOULDBLOCK (reported
315 and analyzed by Yasuhiro MATSUMOTO).
316 - clarified libcoro license and copyright.
317 - someone stole my EXTRA_META!!!
318 - implement Coro::Select::patch_pp_sselect and it's brother,
319 for hardcode select overriding.
320
3215.151 Mon Jul 6 05:41:57 CEST 2009
322 - backport to windows process emulation code again (patch by
323 Yasuhiro MATSUMOTO).
324 - slightly update Coro::MakeMaker.
325
3265.15 Tue Jun 30 10:28:06 CEST 2009
327 - deprecate Coro::Socket, document how to get ipv6 support via
328 AnyEvent::Socket instead.
329 - implement signal->wait ($cb) interface, similar to semaphores.
330 - work around SvOK not supporting getmagic, so we have to getmagic
331 to test for undef :/ (reported by Matthias Waldorf).
332 - load Coro::AnyEvent in all modules using AnyEvent.
333 - work around perl corrupting our internal data structures,
334 reported by Tokuhiro Matsuno.
335 - enable per-coroutine real and cpu time gathering
336 (Coro::State::enable_times).
337
3385.14 Wed Jun 24 01:37:48 CEST 2009
339 - provide explicit functions to "cede" to the event loop in Coro::AnyEvent,
340 as this seems to have been a difficult concept (poll, sleep, idle,
341 idle_upto).
342 - add Coro::AnyEvent::readable/writable functions.
343 - clarify Coro::EV/Event/AnyEvent manpages.
344 - free per-thread global scalars in the thread calling ->cancel, to
345 avoid crashes when $_, $@ etc., are magical but some of those
346 had already been freed.
347 - "unexperimentalise" the callback interface for Coro::Semaphore.
348 - speed up ready queue management/context switching by using a linked
349 list instead of an array (~5-10%).
350 - implement "watch" command in Coro::Debug shells.
351 - for fun, implement time-slicing as an example in the manpage.
352 - if AnyEvent detects EV or Event, but we don't have Coro::EV or
353 Coro::Event, use the normal AnyEvent handling instead of dieing
354 (the same is true for Coro::Handle).
355 - properly document Coro::EV::timed_io_once.
356 - avoid unneccessary ->cancel calls in Coro::Handle.
357 - maybe make it work on mingw32 with win32 backend
358 (based on patch by Yasuhiro Matsumoto).
