10 10
11 - quickly (re)-ported to minix 3.3 before minix crashed again.
12
136.54 Sun Dec 16 11:06:07 CET 2018
14 - reinstate Coro::Select::select prototype - it breaks more than it fixes.
15
166.53 Sun Dec 16 10:33:15 CET 2018
17 - the autogenerated prototypes of Coro::AIO now add ";" at the end
18 to avoid generating named unary operators and messing up parsing
19 (mostly affects aio_mlockall 4 | 8 which was parsed as
20 (aio_mlockall 4) | 8).
21 - do not use a prototype for select in Coro::Select, as CORE::select also
22 doesn't have one.
23
246.52 Tue Aug 14 18:49:43 CEST 2018
25 - libcoro update: allow sharing of coro threads using the pthreads
26 backend among different pthreads, as is required by Coro::Multicore.
27 - always allow ->call and ->eval when the coro is the current coroutine. this
28 makes it possible, among other things, to call these on $Coro::main.
29 - minor code cleanups.
30
316.514 Thu Aug 31 18:25:31 CEST 2017
32 - safe_cancel no longer croaks when called on already-destroyed
33 thread, but instead "just works".
34
356.513 Sat Jul 15 01:18:51 CEST 2017
36 - experimental 5.22 comaptibility changes (PadlistNAMES).
37 - removed attributes example and made sure the other examples
38 still work.
39 - fix some statevar types for newer perls, should be of no consequence.
40
416.512 Fri Jul 14 05:03:17 CEST 2017
42 - seems to pass test suite down till 5.8.9, so make this the
43 minimum requirement in Makefile.PL.
44 - experimental 5.24 compatibility changes (SUB_ARGARRAY).
45 - experimental 5.26 compatibility changes (PL_comppad -> PADOFFSET).
46 - disable FORTIFY_SOURCE to avoid broken (but well-intentioned)
47 fortified longjmp variants in some libcs.
48 - re-try JIT allocation without PROT_EXEC, to hopefully improve
49 portability (still doesn't seem to work around broken selinux
50 mmap everywhere).
51 - speling fixes (Xavier Guimard).
52
536.511 Sun Jun 26 23:44:50 CEST 2016
54 - make it compile with threaded perls again.
55 - simplify and speed up __DIE__ and __WARN__ handling.
56
576.51 Sat Jun 25 20:57:20 CEST 2016
58 - 6.5 release didn't compile on most older perls due to
59 a logic error enabling experimental 5.24 code for all versions.
60 - since various broken or deficient patches float around
61 to work around the vtbl API breakage in perl, let's provide
62 our own workaround, which seems to be much less invasive
63 and more compatible than the approaches seen so far. YMMV.
64 - work around assertion failure in perl_destruct on 5.24
65 (analyzed by Dave Mitchell).
66
676.5 Wed Jun 22 22:23:50 CEST 2016
68 - swap_sv swapping order was not symmetrical, causing
69 wrong swaps when swap_sv was used multiple times on the
70 same sv in the same thread.
71 - swap_sv calls can now be undone by calling it again
72 with the same variables.
73 - swap_sv calls will now be undone in async_pool threads.
74 - split Coro::Semaphore::up/adjust into separate xs functions
75 for better error reporting, at slight codesize increase.
76 - (libcoro) arm assembly support, please test and report.
77 - adjust to PL_savestack changes in perl 5.24 (adapted from
78 the debian patch, which unfortunately gets it wrong).
79
806.49 Sat Oct 17 01:40:12 CEST 2015
81 - throwing an exception to a thread waiting in
82 Coro::Handle using Coro::EV did not stop the watchers,
83 causing the next call to fail (testcase by Martin Pritchard).
84 - bump minimum perl version to 5.10.
85
866.48 Sun Oct 4 19:03:51 CEST 2015
87 - fix memory leak when Coro::Handle uses Coro::EV internally
88 (testcase by Sten Sten).
89 - update code to libev 4 API (internally, Coro still used the
90 version 3 API calls).
91 - remove unused hv_sig.
92
936.47 Sat Jul 11 03:58:20 CEST 2015
94 - swap_svs - NVs can be in the SV head beginning with 5.20.
95
966.46 Tue Jun 30 14:36:30 CEST 2015
97 - restore portability to perls with windows fork emulation
98 (patch by Petr Písař).
99
1006.45 Tue Jun 30 01:40:08 CEST 2015
101 - restore portability to perl 5.16 and below.
102
1036.44 Tue Jun 30 00:41:54 CEST 2015
104 - avoid segfaulting (or worse) when tracing a canceled thread.
105 - the Event module silently broke it's public hook API, causing
106 failures on perls compiled with -Duselongdouble. Requiring
107 the latest version of Event because I don't know which release
108 changed this (it's not mentioned in the ChangeLog).
109 - allow xs level enterleave hooks via CoroAPI.
110
1116.43 Thu Jun 4 15:38:14 CEST 2015
112 - use stability canary.
113 - port to stableperl-5.22.0-1.001.
114 - update libecb.
115
1166.42 Wed Feb 11 20:29:52 CET 2015
117 - Coro::SemaphoreSet->try did not actually work (analyzed by
118 SATO Kentaro).
119 - upgrade libecb to be C11 compliant.
120
1216.41 Sat Sep 6 22:08:46 CEST 2014
122 - restore portability to perl 5.8.x.
123 - give new Coro's a valid GvHV(PL_hintgv) - this is slow and takes
124 up some memory, but fixes "use feature" and similar modules
125 when used inside a Coro.
126 - allow zero as argument to Coro::Channel to mean the same thing
127 as no argument. this works with older versions as well,
128 but wasn't legal until now.
129 - slightly better c header file detection.
130
1316.39 Mon Jun 2 00:00:08 CEST 2014
132 - work around more incompatible changes in 5.20.
133
1346.38 Sun Jun 1 21:54:23 CEST 2014
135 - check that perl slots actually have enough space to hold
136 interpreter variables.
137 - untested port to perl 5.19 (64 bit tmps indices) (reported
138 by Andreas König).
139 - croak when cancel is called without a thread context.
140
1416.37 Tue Mar 4 13:27:33 CET 2014
142 - *sigh*, removed leftover debugging code from debugging a
143 perl bug, of all things.
144
1456.36 Tue Mar 4 07:11:59 CET 2014
146 - semaphores would not clear the destroy hook when interrupted
147 by ->throw, causing segfaults or worse.
148 - ->throw on a thread waiting for a semaphore did not acquire
149 the semaphore, but also didn't wake up other waiters,
150 possibly causing a deadlock.
151 - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess
152 to report a full stacktrace, which should help find out
153 where the actual call is.
154 - "atomically" destroy data in slf_destroy, because it is
155 the right thing to do, just in case.
156 - disable ecb.h libm dependency, to compile on ancient systems
157 or under adverse conditions.
158
1596.33 Mon Nov 18 11:26:27 CET 2013
160 - do not crash when freeing padlists with holes (in 5.18).
161 - tentative SVt_BIND 5.19 port/fix.
162
1636.32 Tue Nov 5 15:35:35 CET 2013
164 - use a new algorithm to derive padlists for perl 5.18. The old
165 one could lead to 0-pointer accesses inside perl (reported
166 by Darin McBride).
167
1686.31 Thu May 9 07:39:48 CEST 2013
169 - Coro::AIO requests would crash if the thread was ready'd
170 while the request was ongoing.
171
1726.29 Wed May 8 02:55:18 CEST 2013
173 - when an on_destroy handler destructs the coro currently being
174 destructed a perl scalar could be accessed after being freed,
175 likely causing a crash.
176
1776.28 Wed Mar 6 06:58:02 CET 2013
178 - clean remnants of existing __DIE__ and __WARN__ handlers so
179 they lose their magic and will not cause segfaults later
180 (testcase by Andrey Sagulin).
181 - improved Coro::State documentation a bit.
182 - Coro::Debug::command now flushes the output.
183 - add hack detection code for x32 abi, because the braindead slugs
184 who designed that made it look exactly like x86_64 without
185 providing proper compile time symbols to test for it. as a result,
186 this detection cannot work reliably.
187 - valgrind stack registering was broken.
188 - do not rely on Time::HiRes anymore in Coro::Debug.
189
1906.23 Fri Dec 7 23:36:37 CET 2012
191 - use experimental fiber implementation on native windows
192 perls.
193 - use sizeof (void *) as multiplication factor for stack sizes,
194 to accomodate the totally braindamaged microsoft 64 bit "os".
195 - changed verifier host from win2k-ap510-32 to win7-sp516-32/64.
196 activeperl 5.16 crashes when PerlIO_define_layer is called due
197 to some bug in the perl dll, strawberry perl at least passes
198 the testsuite.
199 - implement Coro::Handle->peeraddr/host/port, for slightly
200 improved compatibility with LWP.
201 - implement 5.17 compatibility by almost blindly applying a
202 good-looking patch by Father Chrysostomos.
203 - move stack management functions into libcoro 3.
204 - libcoro version 3 "released".
205 - support magic values as timed_io_once args.
206 - recommend AnyEvent 7+ or EV 4+, also require EV
207 version 4 or newer for Coro::EV.
208
2096.10 Tue Oct 9 01:14:27 CEST 2012
210 - updated ecb.h, it had a typo that caused it to not compile on many
211 big endian systems (reported by many people).
212 - disable memory fences in ecb.h to improve portability.
213
2146.09 Sat Oct 6 23:25:02 CEST 2012
215 - Coro::EV I/O watchers were not interruptible by exceptions
216 (Coro::State::throw) (testcase by sten).
217 - ->throw now puts threads into the ready queue, as this seems to
218 be expected by existing code, and code that doesn't cope with spurious
219 wakeups needs fixing anyway.
220 - use fd -1 in mmap.
221 - cast I32 to int in error message printf.
222 - warn about broken so-called "hardened" kernels.
223
2246.08 Fri Apr 13 12:05:47 CEST 2012
225 - be more aggressive about exiting like perl does - formerly,
226 exiting from the non-main thread would not execute END blocks.
227
2286.07 Fri Nov 11 21:21:48 CET 2011
229 - work around a bug in PerlIO (setting $SIG{__WARN__} to a PVCV).
230 - update ecb.h.
231
2326.06 Mon Aug 8 23:59:48 CEST 2011
233 - cygwin unfortunately patches the stack at runtime, so we use the pthreads
234 backend, which is an order of magnitude slower. unfortunately, cygwins
235 pthread implementation isn't very complete either, so allocate the stack
236 twice just to be sure.
237 (note: cygwin also enables mymalloc, which is NOT THREADSAFE ON WINDOWS,
238 in its ithreaded perl - best recompile cygwin and use the 'w'indows
239 backend for much better performance. also disable ithreads for
240 even better performance...).
241
2426.05 Thu Aug 4 21:36:36 CEST 2011
243 - blush, condvar values would not be propagated from send to recv anymore
244 (reported by Chip Salzenberg).
245 - use exponential increase for the readline buffer length in
246 Coro::Handle. also reduce initial allocation to 1020 from 4096 bytes.
247
2486.04 Wed Aug 3 17:15:45 CEST 2011
249 - use even more efficient and more compatible condvars for
250 compatibility to AnyEvent 6.x :)
251 - more inconsequential ecb.h updates.
252
2536.03 Wed Aug 3 11:41:30 CEST 2011
254 - change how Coro patches AnyEvent condvars for compatibility to
255 AnyEvent 6.x.
256 - update ecb.h, to no longer include <pthread.h> in case WinNT.h
257 hasn't been included.
258
2596.02 Wed Jul 13 04:35:19 CEST 2011
260 - "improve portability to Gentoo" - gentoo manages to put perl variables
261 in memory areas that are farther than 2gb apart, which the jit couldn't
262 handle and barfed. now it's just a bit slower on gentoo and similar
263 systems.
264
2656.01 Sun Jul 3 12:31:14 CEST 2011
266 - workarounds are good, but the test for whether pthreads are used
267 was not good. this one should be better.
268 - check differently whether gcc generates cfi instructions itself.
269
2706.0 Wed Jun 29 19:43:35 CEST 2011
271 - INCOMPATIBLE CHANGE: unreferenced coro objects will now be
272 destroyed and cleaned up automatically (e.g. async { schedule }).
273 - implement a JIT compiler for part of the thread switch code,
274 which gives a 50% speed improvement on threaded perls, and
275 about 4% on non-threaded perls (so threaded perls now finally
276 reach about half the speed of non-threaded perls).
277 - slightly modernise Coro::Intro, add section about rouse functions.
278 - avoid DEFSV and ERRSV, giving another 10% improvement
279 in thread switching.
280 - Coro::State->is_destroyed is now called is_zombie.
281 - implement a Coro->safe_cancel method that might fail, but
282 cancels in a "safer" way if it succeeds.
283 - add preliminary support for DEBUGGING perls.
284 - get rid of two hash-accesses when initialising a new Coro - this
285 speeds up coro creation by almost a factor of two.
286 - croak when a coro that is being cancelled tries to block
287 (e.g. while executing a guard block), instead of crashing or
288 deadlocking.
289 - use a more robust and also faster method to identify Coro::State
290 objects - speeds up everything a bit.
291 - implement Coro->cancel in XS for a 20% speed improvement, and to
292 be able to implement mutual cancellation.
293 - speed up context switches by a percent or two by more efficiently
294 allocating context stack entries.
295 - implement Coro->join and Coro->on_destroy in XS for a speedup and
296 a reduction in memory use.
297 - cancelling a coro while it itself is cancelling another coro is
298 now supported and working, instead of triggering an assertion.
299 - be a bit more crash-resistant when calling (buggy) on_destroy
300 callbacks (best effort).
301 - move on_destroy into the slf_frame, to allow extension slf
302 functions to have destructors.
303 - get rid if coro refcounting - simply crash in other interpreter
304 threads by nulling the pointers on clone.
305 - simplify warn/die hook handling when loading Coro - the convoluted
306 logic seems to be no longer neccessary.
307 - use libecb instead of our own home-grown gcc hacks.
308 - document alternatives to Coro::LWP. Please use them :)
309 - work around another mindless idiotic NEEDLESS bug in openbsd/mirbsds
310 sigaltstack. Really. wine suffers from it, erlang suffers from it,
311 and it's known since at least 2006.
312
3135.372 Wed Feb 23 06:14:30 CET 2011
314 - apparently mingw doesn't provide a working gettimeofday, try to
315 work around that by relying on Time::HiRes (indirectly brought to
316 my attention by Max Maischein).
317 - fix some portability issues when Time::HiRes was used.
318
3195.371 Mon Feb 21 14:36:08 CET 2011
320 - backport to windows process emulation code again.
321
3225.37 Sat Feb 19 07:49:44 CET 2011
323 - add a big "Coro thread life cycle" section to "man Coro".
324 - try a tentative workaround against the breakage that 5.13 has
325 introduced without depreciation period. sigh.
326 - no longer use Time::HiRes if gettimeofday is available, which
327 saves quite a lot of memory.
328
3295.36 Sun Feb 13 05:33:41 CET 2011
330 - automatically load Coro::Channel, Coro::RWLock, Coro::Semaphore,
331 Coro::SemaphoreSet, Coro::Signal and Coro::Specific on first "new"
332 method call.
333 - undocument Coro::Timer::sleep and obsolete whole module.
334 - optimise Coro::Timer::timeout memory and cpu usage.
335 - slightly updated Coro::Intro for recent changes.
336 - do not initialise PL_dirty anymore.
337
3385.25 Thu Nov 11 01:08:39 CET 2010
339 - try a different approach on netbsd - netbsd 5 finally has marginally
340 working pthreads, but still broken ucontext/sigaltstack.
341 - openbsd 4.8 finally got their act together, Coro works out of the box
342 with asm, setjmp and pthreads (no change, just informational).
343
3445.24 Sat Oct 23 11:27:12 CEST 2010
345 - port to the EV 4.0 API.
346 - work around bugs in mingw32, making strawberry perl work
347 out of the box.
348 - correctly modify Coro::AIO function prototypes
349 so that they reflect the "no optional parameters" rule.
350 - "ported" libcoro to C++.
351
3525.23 Mon May 17 18:50:42 CEST 2010
353 - be more resistant to ordering changes when initialising
354 Coro::AnyEvent, Coro::EV and Coro::Event (reported by Matthias
355 Waldorf).
356 - document that perl 5.12 deliberately removed support for cloning.
357
3585.22 Wed Apr 14 03:55:35 CEST 2010
359 - correctly return udnef on errors in Coro::Handle::read/write
360 (testcase by Marc Mims).
11 - convert Coro::Util into a "perl compatibility wrapper" - the functions 361 - convert Coro::Util into a "perl compatibility wrapper" - the functions

15 with Coro::Util::inet_aton. 365 with Coro::Util::inet_aton.
366 - do not override $Coro::idle unconditionally in Coro.pm, as other
367 modules could have provided their own idle coro already
368 (for exmaple, Coro::AnyEvent).
16 - fix Coro::Util::gethost* functions. 369 - fix Coro::Util::gethost* functions.
370 - Coro::Timer corretcly exports it's symbols (reported by Hideki Yamamura).
