136.57
14 - allow rouse_wait to be called in a different thread.
15 - slightly clarify rouse_cb/rouse_wait documentation.
16 - slightly improve rouse callback performance and memory usage.
17
186.56 Thu Feb 20 19:40:07 CET 2020
19 - Coro::EV::time*once functions used ev_once, which is not cancelable.
20 This could cause problems due to I/O watchers not being stopped up
21 on exceptions/cancellation.
22
236.55 Fri Jul 19 17:28:09 CEST 2019
24 - Coro::RWLock woke up only one reader instead of all after a wrlock
25 (analyzed and patch by Maxim Skorobogatov).
26 - slightly improved documentation of Coro::RWLock and RWLock testcase.
27 - quickly (re)-ported to minix 3.3 before minix crashed again.
28
296.54 Sun Dec 16 11:06:07 CET 2018
30 - reinstate Coro::Select::select prototype - it breaks more than it fixes.
31
326.53 Sun Dec 16 10:33:15 CET 2018
33 - the autogenerated prototypes of Coro::AIO now add ";" at the end
34 to avoid generating named unary operators and messing up parsing
35 (mostly affects aio_mlockall 4 | 8 which was parsed as
36 (aio_mlockall 4) | 8).
37 - do not use a prototype for select in Coro::Select, as CORE::select also
38 doesn't have one.
39
406.52 Tue Aug 14 18:49:43 CEST 2018
41 - libcoro update: allow sharing of coro threads using the pthreads
42 backend among different pthreads, as is required by Coro::Multicore.
43 - always allow ->call and ->eval when the coro is the current coroutine. this
44 makes it possible, among other things, to call these on $Coro::main.
45 - minor code cleanups.
46
476.514 Thu Aug 31 18:25:31 CEST 2017
48 - safe_cancel no longer croaks when called on already-destroyed
49 thread, but instead "just works".
50
516.513 Sat Jul 15 01:18:51 CEST 2017
52 - experimental 5.22 comaptibility changes (PadlistNAMES).
53 - removed attributes example and made sure the other examples
54 still work.
55 - fix some statevar types for newer perls, should be of no consequence.
56
576.512 Fri Jul 14 05:03:17 CEST 2017
58 - seems to pass test suite down till 5.8.9, so make this the
59 minimum requirement in Makefile.PL.
60 - experimental 5.24 compatibility changes (SUB_ARGARRAY).
61 - experimental 5.26 compatibility changes (PL_comppad -> PADOFFSET).
62 - disable FORTIFY_SOURCE to avoid broken (but well-intentioned)
63 fortified longjmp variants in some libcs.
64 - re-try JIT allocation without PROT_EXEC, to hopefully improve
65 portability (still doesn't seem to work around broken selinux
66 mmap everywhere).
67 - speling fixes (Xavier Guimard).
68
696.511 Sun Jun 26 23:44:50 CEST 2016
70 - make it compile with threaded perls again.
71 - simplify and speed up __DIE__ and __WARN__ handling.
72
736.51 Sat Jun 25 20:57:20 CEST 2016
74 - 6.5 release didn't compile on most older perls due to
75 a logic error enabling experimental 5.24 code for all versions.
76 - since various broken or deficient patches float around
77 to work around the vtbl API breakage in perl, let's provide
78 our own workaround, which seems to be much less invasive
79 and more compatible than the approaches seen so far. YMMV.
80 - work around assertion failure in perl_destruct on 5.24
81 (analyzed by Dave Mitchell).
82
836.5 Wed Jun 22 22:23:50 CEST 2016
84 - swap_sv swapping order was not symmetrical, causing
85 wrong swaps when swap_sv was used multiple times on the
86 same sv in the same thread.
87 - swap_sv calls can now be undone by calling it again
88 with the same variables.
89 - swap_sv calls will now be undone in async_pool threads.
90 - split Coro::Semaphore::up/adjust into separate xs functions
91 for better error reporting, at slight codesize increase.
92 - (libcoro) arm assembly support, please test and report.
93 - adjust to PL_savestack changes in perl 5.24 (adapted from
94 the debian patch, which unfortunately gets it wrong).
95
966.49 Sat Oct 17 01:40:12 CEST 2015
97 - throwing an exception to a thread waiting in
98 Coro::Handle using Coro::EV did not stop the watchers,
99 causing the next call to fail (testcase by Martin Pritchard).
100 - bump minimum perl version to 5.10.
101
1026.48 Sun Oct 4 19:03:51 CEST 2015
103 - fix memory leak when Coro::Handle uses Coro::EV internally
104 (testcase by Sten Sten).
105 - update code to libev 4 API (internally, Coro still used the
106 version 3 API calls).
107 - remove unused hv_sig.
108
1096.47 Sat Jul 11 03:58:20 CEST 2015
110 - swap_svs - NVs can be in the SV head beginning with 5.20.
111
1126.46 Tue Jun 30 14:36:30 CEST 2015
113 - restore portability to perls with windows fork emulation
114 (patch by Petr Písař).
115
1166.45 Tue Jun 30 01:40:08 CEST 2015
117 - restore portability to perl 5.16 and below.
118
1196.44 Tue Jun 30 00:41:54 CEST 2015
120 - avoid segfaulting (or worse) when tracing a canceled thread.
121 - the Event module silently broke it's public hook API, causing
122 failures on perls compiled with -Duselongdouble. Requiring
123 the latest version of Event because I don't know which release
124 changed this (it's not mentioned in the ChangeLog).
125 - allow xs level enterleave hooks via CoroAPI.
126
1276.43 Thu Jun 4 15:38:14 CEST 2015
128 - use stability canary.
129 - port to stableperl-5.22.0-1.001.
130 - update libecb.
131
1326.42 Wed Feb 11 20:29:52 CET 2015
133 - Coro::SemaphoreSet->try did not actually work (analyzed by
134 SATO Kentaro).
135 - upgrade libecb to be C11 compliant.
136
1376.41 Sat Sep 6 22:08:46 CEST 2014
138 - restore portability to perl 5.8.x.
139 - give new Coro's a valid GvHV(PL_hintgv) - this is slow and takes
140 up some memory, but fixes "use feature" and similar modules
141 when used inside a Coro.
142 - allow zero as argument to Coro::Channel to mean the same thing
143 as no argument. this works with older versions as well,
144 but wasn't legal until now.
145 - slightly better c header file detection.
146
1476.39 Mon Jun 2 00:00:08 CEST 2014
148 - work around more incompatible changes in 5.20.
149
1506.38 Sun Jun 1 21:54:23 CEST 2014
151 - check that perl slots actually have enough space to hold
152 interpreter variables.
153 - untested port to perl 5.19 (64 bit tmps indices) (reported
154 by Andreas König).
155 - croak when cancel is called without a thread context.
156
1576.37 Tue Mar 4 13:27:33 CET 2014
158 - *sigh*, removed leftover debugging code from debugging a
159 perl bug, of all things.
160
1616.36 Tue Mar 4 07:11:59 CET 2014
162 - semaphores would not clear the destroy hook when interrupted
163 by ->throw, causing segfaults or worse.
164 - ->throw on a thread waiting for a semaphore did not acquire
165 the semaphore, but also didn't wake up other waiters,
166 possibly causing a deadlock.
167 - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess
168 to report a full stacktrace, which should help find out
169 where the actual call is.
170 - "atomically" destroy data in slf_destroy, because it is
171 the right thing to do, just in case.
172 - disable ecb.h libm dependency, to compile on ancient systems
173 or under adverse conditions.
174
1756.33 Mon Nov 18 11:26:27 CET 2013
176 - do not crash when freeing padlists with holes (in 5.18).
177 - tentative SVt_BIND 5.19 port/fix.
178
1796.32 Tue Nov 5 15:35:35 CET 2013
180 - use a new algorithm to derive padlists for perl 5.18. The old
181 one could lead to 0-pointer accesses inside perl (reported
182 by Darin McBride).
183
1846.31 Thu May 9 07:39:48 CEST 2013
185 - Coro::AIO requests would crash if the thread was ready'd
186 while the request was ongoing.
187
1886.29 Wed May 8 02:55:18 CEST 2013
189 - when an on_destroy handler destructs the coro currently being
190 destructed a perl scalar could be accessed after being freed,
191 likely causing a crash.
192
1936.28 Wed Mar 6 06:58:02 CET 2013
194 - clean remnants of existing __DIE__ and __WARN__ handlers so
195 they lose their magic and will not cause segfaults later
196 (testcase by Andrey Sagulin).
197 - improved Coro::State documentation a bit.
198 - Coro::Debug::command now flushes the output.
199 - add hack detection code for x32 abi, because the braindead slugs
200 who designed that made it look exactly like x86_64 without
201 providing proper compile time symbols to test for it. as a result,
202 this detection cannot work reliably.
203 - valgrind stack registering was broken.
204 - do not rely on Time::HiRes anymore in Coro::Debug.
205
2066.23 Fri Dec 7 23:36:37 CET 2012
207 - use experimental fiber implementation on native windows
208 perls.
209 - use sizeof (void *) as multiplication factor for stack sizes,
210 to accomodate the totally braindamaged microsoft 64 bit "os".
211 - changed verifier host from win2k-ap510-32 to win7-sp516-32/64.
212 activeperl 5.16 crashes when PerlIO_define_layer is called due
213 to some bug in the perl dll, strawberry perl at least passes
214 the testsuite.
215 - implement Coro::Handle->peeraddr/host/port, for slightly
216 improved compatibility with LWP.
217 - implement 5.17 compatibility by almost blindly applying a
218 good-looking patch by Father Chrysostomos.
219 - move stack management functions into libcoro 3.
220 - libcoro version 3 "released".
221 - support magic values as timed_io_once args.
222 - recommend AnyEvent 7+ or EV 4+, also require EV
223 version 4 or newer for Coro::EV.
224
2256.10 Tue Oct 9 01:14:27 CEST 2012
226 - updated ecb.h, it had a typo that caused it to not compile on many
227 big endian systems (reported by many people).
228 - disable memory fences in ecb.h to improve portability.
229
2306.09 Sat Oct 6 23:25:02 CEST 2012
231 - Coro::EV I/O watchers were not interruptible by exceptions
232 (Coro::State::throw) (testcase by sten).
233 - ->throw now puts threads into the ready queue, as this seems to
234 be expected by existing code, and code that doesn't cope with spurious
235 wakeups needs fixing anyway.
236 - use fd -1 in mmap.
237 - cast I32 to int in error message printf.
238 - warn about broken so-called "hardened" kernels.
239
2406.08 Fri Apr 13 12:05:47 CEST 2012
241 - be more aggressive about exiting like perl does - formerly,
242 exiting from the non-main thread would not execute END blocks.
243
2446.07 Fri Nov 11 21:21:48 CET 2011
245 - work around a bug in PerlIO (setting $SIG{__WARN__} to a PVCV).
246 - update ecb.h.
247
2486.06 Mon Aug 8 23:59:48 CEST 2011
249 - cygwin unfortunately patches the stack at runtime, so we use the pthreads
250 backend, which is an order of magnitude slower. unfortunately, cygwins
251 pthread implementation isn't very complete either, so allocate the stack
252 twice just to be sure.
253 (note: cygwin also enables mymalloc, which is NOT THREADSAFE ON WINDOWS,
254 in its ithreaded perl - best recompile cygwin and use the 'w'indows
255 backend for much better performance. also disable ithreads for
256 even better performance...).
257
2586.05 Thu Aug 4 21:36:36 CEST 2011
259 - blush, condvar values would not be propagated from send to recv anymore
260 (reported by Chip Salzenberg).
261 - use exponential increase for the readline buffer length in
262 Coro::Handle. also reduce initial allocation to 1020 from 4096 bytes.
263
2646.04 Wed Aug 3 17:15:45 CEST 2011
265 - use even more efficient and more compatible condvars for
266 compatibility to AnyEvent 6.x :)
267 - more inconsequential ecb.h updates.
268
2696.03 Wed Aug 3 11:41:30 CEST 2011
270 - change how Coro patches AnyEvent condvars for compatibility to
271 AnyEvent 6.x.
272 - update ecb.h, to no longer include <pthread.h> in case WinNT.h
273 hasn't been included.
274
2756.02 Wed Jul 13 04:35:19 CEST 2011
276 - "improve portability to Gentoo" - gentoo manages to put perl variables
277 in memory areas that are farther than 2gb apart, which the jit couldn't
278 handle and barfed. now it's just a bit slower on gentoo and similar
279 systems.
280
2816.01 Sun Jul 3 12:31:14 CEST 2011
282 - workarounds are good, but the test for whether pthreads are used
283 was not good. this one should be better.
284 - check differently whether gcc generates cfi instructions itself.
285
2866.0 Wed Jun 29 19:43:35 CEST 2011
287 - INCOMPATIBLE CHANGE: unreferenced coro objects will now be
288 destroyed and cleaned up automatically (e.g. async { schedule }).
289 - implement a JIT compiler for part of the thread switch code,
290 which gives a 50% speed improvement on threaded perls, and
291 about 4% on non-threaded perls (so threaded perls now finally
292 reach about half the speed of non-threaded perls).
293 - slightly modernise Coro::Intro, add section about rouse functions.
294 - avoid DEFSV and ERRSV, giving another 10% improvement
295 in thread switching.
296 - Coro::State->is_destroyed is now called is_zombie.
297 - implement a Coro->safe_cancel method that might fail, but
298 cancels in a "safer" way if it succeeds.
299 - add preliminary support for DEBUGGING perls.
300 - get rid of two hash-accesses when initialising a new Coro - this
301 speeds up coro creation by almost a factor of two.
302 - croak when a coro that is being cancelled tries to block
303 (e.g. while executing a guard block), instead of crashing or
304 deadlocking.
305 - use a more robust and also faster method to identify Coro::State
306 objects - speeds up everything a bit.
307 - implement Coro->cancel in XS for a 20% speed improvement, and to
308 be able to implement mutual cancellation.
309 - speed up context switches by a percent or two by more efficiently
310 allocating context stack entries.
311 - implement Coro->join and Coro->on_destroy in XS for a speedup and
312 a reduction in memory use.
313 - cancelling a coro while it itself is cancelling another coro is
314 now supported and working, instead of triggering an assertion.
315 - be a bit more crash-resistant when calling (buggy) on_destroy
316 callbacks (best effort).
317 - move on_destroy into the slf_frame, to allow extension slf
318 functions to have destructors.
319 - get rid if coro refcounting - simply crash in other interpreter
320 threads by nulling the pointers on clone.
321 - simplify warn/die hook handling when loading Coro - the convoluted
322 logic seems to be no longer neccessary.
323 - use libecb instead of our own home-grown gcc hacks.
324 - document alternatives to Coro::LWP. Please use them :)
325 - work around another mindless idiotic NEEDLESS bug in openbsd/mirbsds
326 sigaltstack. Really. wine suffers from it, erlang suffers from it,
327 and it's known since at least 2006.
328
3295.372 Wed Feb 23 06:14:30 CET 2011
330 - apparently mingw doesn't provide a working gettimeofday, try to
331 work around that by relying on Time::HiRes (indirectly brought to
332 my attention by Max Maischein).
333 - fix some portability issues when Time::HiRes was used.
334
3355.371 Mon Feb 21 14:36:08 CET 2011
336 - backport to windows process emulation code again.
337
3385.37 Sat Feb 19 07:49:44 CET 2011
339 - add a big "Coro thread life cycle" section to "man Coro".
340 - try a tentative workaround against the breakage that 5.13 has
341 introduced without depreciation period. sigh.
342 - no longer use Time::HiRes if gettimeofday is available, which
343 saves quite a lot of memory.
344
3455.36 Sun Feb 13 05:33:41 CET 2011
346 - automatically load Coro::Channel, Coro::RWLock, Coro::Semaphore,
347 Coro::SemaphoreSet, Coro::Signal and Coro::Specific on first "new"
348 method call.
349 - undocument Coro::Timer::sleep and obsolete whole module.
350 - optimise Coro::Timer::timeout memory and cpu usage.
351 - slightly updated Coro::Intro for recent changes.
352 - do not initialise PL_dirty anymore.
353
3545.25 Thu Nov 11 01:08:39 CET 2010

357 - openbsd 4.8 finally got their act together, Coro works out of the box
358 with asm, setjmp and pthreads (no change, just informational).
