13
146.56 Thu Feb 20 19:40:07 CET 2020
15 - Coro::EV::time*once functions used ev_once, which is not cancelable.
16 This could cause problems due to I/O watchers not being stopped up
17 on exceptions/cancellation.
18
196.55 Fri Jul 19 17:28:09 CEST 2019
20 - Coro::RWLock woke up only one reader instead of all after a wrlock
21 (analyzed and patch by Maxim Skorobogatov).
22 - slightly improved documentation of Coro::RWLock and RWLock testcase.
23 - quickly (re)-ported to minix 3.3 before minix crashed again.
24
256.54 Sun Dec 16 11:06:07 CET 2018
26 - reinstate Coro::Select::select prototype - it breaks more than it fixes.
27
286.53 Sun Dec 16 10:33:15 CET 2018
29 - the autogenerated prototypes of Coro::AIO now add ";" at the end
30 to avoid generating named unary operators and messing up parsing
31 (mostly affects aio_mlockall 4 | 8 which was parsed as
32 (aio_mlockall 4) | 8).
33 - do not use a prototype for select in Coro::Select, as CORE::select also
34 doesn't have one.
35
366.52 Tue Aug 14 18:49:43 CEST 2018
37 - libcoro update: allow sharing of coro threads using the pthreads
38 backend among different pthreads, as is required by Coro::Multicore.
39 - always allow ->call and ->eval when the coro is the current coroutine. this
40 makes it possible, among other things, to call these on $Coro::main.
41 - minor code cleanups.
42
436.514 Thu Aug 31 18:25:31 CEST 2017
44 - safe_cancel no longer croaks when called on already-destroyed
45 thread, but instead "just works".
46
476.513 Sat Jul 15 01:18:51 CEST 2017
48 - experimental 5.22 comaptibility changes (PadlistNAMES).
49 - removed attributes example and made sure the other examples
50 still work.
51 - fix some statevar types for newer perls, should be of no consequence.
52
536.512 Fri Jul 14 05:03:17 CEST 2017
54 - seems to pass test suite down till 5.8.9, so make this the
55 minimum requirement in Makefile.PL.
56 - experimental 5.24 compatibility changes (SUB_ARGARRAY).
57 - experimental 5.26 compatibility changes (PL_comppad -> PADOFFSET).
58 - disable FORTIFY_SOURCE to avoid broken (but well-intentioned)
59 fortified longjmp variants in some libcs.
60 - re-try JIT allocation without PROT_EXEC, to hopefully improve
61 portability (still doesn't seem to work around broken selinux
62 mmap everywhere).
63 - speling fixes (Xavier Guimard).
64
656.511 Sun Jun 26 23:44:50 CEST 2016
66 - make it compile with threaded perls again.
67 - simplify and speed up __DIE__ and __WARN__ handling.
68
696.51 Sat Jun 25 20:57:20 CEST 2016
70 - 6.5 release didn't compile on most older perls due to
71 a logic error enabling experimental 5.24 code for all versions.
72 - since various broken or deficient patches float around
73 to work around the vtbl API breakage in perl, let's provide
74 our own workaround, which seems to be much less invasive
75 and more compatible than the approaches seen so far. YMMV.
76 - work around assertion failure in perl_destruct on 5.24
77 (analyzed by Dave Mitchell).
78
796.5 Wed Jun 22 22:23:50 CEST 2016
80 - swap_sv swapping order was not symmetrical, causing
81 wrong swaps when swap_sv was used multiple times on the
82 same sv in the same thread.
83 - swap_sv calls can now be undone by calling it again
84 with the same variables.
85 - swap_sv calls will now be undone in async_pool threads.
86 - split Coro::Semaphore::up/adjust into separate xs functions
87 for better error reporting, at slight codesize increase.
88 - (libcoro) arm assembly support, please test and report.
89 - adjust to PL_savestack changes in perl 5.24 (adapted from
90 the debian patch, which unfortunately gets it wrong).
91
926.49 Sat Oct 17 01:40:12 CEST 2015
93 - throwing an exception to a thread waiting in
94 Coro::Handle using Coro::EV did not stop the watchers,
95 causing the next call to fail (testcase by Martin Pritchard).
96 - bump minimum perl version to 5.10.
97
986.48 Sun Oct 4 19:03:51 CEST 2015
99 - fix memory leak when Coro::Handle uses Coro::EV internally
100 (testcase by Sten Sten).
101 - update code to libev 4 API (internally, Coro still used the
102 version 3 API calls).
103 - remove unused hv_sig.
104
1056.47 Sat Jul 11 03:58:20 CEST 2015
106 - swap_svs - NVs can be in the SV head beginning with 5.20.
107
1086.46 Tue Jun 30 14:36:30 CEST 2015
109 - restore portability to perls with windows fork emulation
110 (patch by Petr Písař).
111
1126.45 Tue Jun 30 01:40:08 CEST 2015
113 - restore portability to perl 5.16 and below.
114
1156.44 Tue Jun 30 00:41:54 CEST 2015
116 - avoid segfaulting (or worse) when tracing a canceled thread.
117 - the Event module silently broke it's public hook API, causing
118 failures on perls compiled with -Duselongdouble. Requiring
119 the latest version of Event because I don't know which release
120 changed this (it's not mentioned in the ChangeLog).
121 - allow xs level enterleave hooks via CoroAPI.
122
1236.43 Thu Jun 4 15:38:14 CEST 2015
124 - use stability canary.
125 - port to stableperl-5.22.0-1.001.
126 - update libecb.
127
1286.42 Wed Feb 11 20:29:52 CET 2015
129 - Coro::SemaphoreSet->try did not actually work (analyzed by
130 SATO Kentaro).
131 - upgrade libecb to be C11 compliant.
132
1336.41 Sat Sep 6 22:08:46 CEST 2014
134 - restore portability to perl 5.8.x.
135 - give new Coro's a valid GvHV(PL_hintgv) - this is slow and takes
136 up some memory, but fixes "use feature" and similar modules
137 when used inside a Coro.
138 - allow zero as argument to Coro::Channel to mean the same thing
139 as no argument. this works with older versions as well,
140 but wasn't legal until now.
141 - slightly better c header file detection.
142
1436.39 Mon Jun 2 00:00:08 CEST 2014
144 - work around more incompatible changes in 5.20.
145
1466.38 Sun Jun 1 21:54:23 CEST 2014
147 - check that perl slots actually have enough space to hold
148 interpreter variables.
149 - untested port to perl 5.19 (64 bit tmps indices) (reported
150 by Andreas König).
151 - croak when cancel is called without a thread context.
152
1536.37 Tue Mar 4 13:27:33 CET 2014
154 - *sigh*, removed leftover debugging code from debugging a
155 perl bug, of all things.
156
1576.36 Tue Mar 4 07:11:59 CET 2014
158 - semaphores would not clear the destroy hook when interrupted
159 by ->throw, causing segfaults or worse.
160 - ->throw on a thread waiting for a semaphore did not acquire
161 the semaphore, but also didn't wake up other waiters,
162 possibly causing a deadlock.
163 - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess
164 to report a full stacktrace, which should help find out
165 where the actual call is.
166 - "atomically" destroy data in slf_destroy, because it is
167 the right thing to do, just in case.
168 - disable ecb.h libm dependency, to compile on ancient systems
169 or under adverse conditions.
170
1716.33 Mon Nov 18 11:26:27 CET 2013
172 - do not crash when freeing padlists with holes (in 5.18).
173 - tentative SVt_BIND 5.19 port/fix.
174
1756.32 Tue Nov 5 15:35:35 CET 2013
176 - use a new algorithm to derive padlists for perl 5.18. The old
177 one could lead to 0-pointer accesses inside perl (reported
178 by Darin McBride).
179
1806.31 Thu May 9 07:39:48 CEST 2013
181 - Coro::AIO requests would crash if the thread was ready'd
182 while the request was ongoing.
183
1846.29 Wed May 8 02:55:18 CEST 2013
185 - when an on_destroy handler destructs the coro currently being
186 destructed a perl scalar could be accessed after being freed,
187 likely causing a crash.
188
1896.28 Wed Mar 6 06:58:02 CET 2013
190 - clean remnants of existing __DIE__ and __WARN__ handlers so
191 they lose their magic and will not cause segfaults later
192 (testcase by Andrey Sagulin).
193 - improved Coro::State documentation a bit.
194 - Coro::Debug::command now flushes the output.
195 - add hack detection code for x32 abi, because the braindead slugs
196 who designed that made it look exactly like x86_64 without
197 providing proper compile time symbols to test for it. as a result,
198 this detection cannot work reliably.
199 - valgrind stack registering was broken.
200 - do not rely on Time::HiRes anymore in Coro::Debug.
201
2026.23 Fri Dec 7 23:36:37 CET 2012
203 - use experimental fiber implementation on native windows
204 perls.
205 - use sizeof (void *) as multiplication factor for stack sizes,
206 to accomodate the totally braindamaged microsoft 64 bit "os".
207 - changed verifier host from win2k-ap510-32 to win7-sp516-32/64.
208 activeperl 5.16 crashes when PerlIO_define_layer is called due
209 to some bug in the perl dll, strawberry perl at least passes
210 the testsuite.
211 - implement Coro::Handle->peeraddr/host/port, for slightly
212 improved compatibility with LWP.
213 - implement 5.17 compatibility by almost blindly applying a
214 good-looking patch by Father Chrysostomos.
215 - move stack management functions into libcoro 3.
216 - libcoro version 3 "released".
217 - support magic values as timed_io_once args.
218 - recommend AnyEvent 7+ or EV 4+, also require EV
219 version 4 or newer for Coro::EV.
220
2216.10 Tue Oct 9 01:14:27 CEST 2012
222 - updated ecb.h, it had a typo that caused it to not compile on many
223 big endian systems (reported by many people).
224 - disable memory fences in ecb.h to improve portability.
225
2266.09 Sat Oct 6 23:25:02 CEST 2012
227 - Coro::EV I/O watchers were not interruptible by exceptions
228 (Coro::State::throw) (testcase by sten).
229 - ->throw now puts threads into the ready queue, as this seems to
230 be expected by existing code, and code that doesn't cope with spurious
231 wakeups needs fixing anyway.
232 - use fd -1 in mmap.
233 - cast I32 to int in error message printf.
234 - warn about broken so-called "hardened" kernels.
235
2366.08 Fri Apr 13 12:05:47 CEST 2012
237 - be more aggressive about exiting like perl does - formerly,
238 exiting from the non-main thread would not execute END blocks.
239
2406.07 Fri Nov 11 21:21:48 CET 2011
241 - work around a bug in PerlIO (setting $SIG{__WARN__} to a PVCV).
242 - update ecb.h.
243
2446.06 Mon Aug 8 23:59:48 CEST 2011
245 - cygwin unfortunately patches the stack at runtime, so we use the pthreads
246 backend, which is an order of magnitude slower. unfortunately, cygwins
247 pthread implementation isn't very complete either, so allocate the stack
248 twice just to be sure.
249 (note: cygwin also enables mymalloc, which is NOT THREADSAFE ON WINDOWS,
250 in its ithreaded perl - best recompile cygwin and use the 'w'indows
251 backend for much better performance. also disable ithreads for
252 even better performance...).
253
2546.05 Thu Aug 4 21:36:36 CEST 2011
255 - blush, condvar values would not be propagated from send to recv anymore
256 (reported by Chip Salzenberg).
257 - use exponential increase for the readline buffer length in
258 Coro::Handle. also reduce initial allocation to 1020 from 4096 bytes.
259
2606.04 Wed Aug 3 17:15:45 CEST 2011
261 - use even more efficient and more compatible condvars for
262 compatibility to AnyEvent 6.x :)
263 - more inconsequential ecb.h updates.
264
2656.03 Wed Aug 3 11:41:30 CEST 2011
266 - change how Coro patches AnyEvent condvars for compatibility to
267 AnyEvent 6.x.
268 - update ecb.h, to no longer include <pthread.h> in case WinNT.h
269 hasn't been included.
270
2716.02 Wed Jul 13 04:35:19 CEST 2011
272 - "improve portability to Gentoo" - gentoo manages to put perl variables
273 in memory areas that are farther than 2gb apart, which the jit couldn't
274 handle and barfed. now it's just a bit slower on gentoo and similar
275 systems.
276
2776.01 Sun Jul 3 12:31:14 CEST 2011
278 - workarounds are good, but the test for whether pthreads are used
279 was not good. this one should be better.
280 - check differently whether gcc generates cfi instructions itself.
281
2826.0 Wed Jun 29 19:43:35 CEST 2011
283 - INCOMPATIBLE CHANGE: unreferenced coro objects will now be
284 destroyed and cleaned up automatically (e.g. async { schedule }).
285 - implement a JIT compiler for part of the thread switch code,
286 which gives a 50% speed improvement on threaded perls, and
287 about 4% on non-threaded perls (so threaded perls now finally
288 reach about half the speed of non-threaded perls).
289 - slightly modernise Coro::Intro, add section about rouse functions.
290 - avoid DEFSV and ERRSV, giving another 10% improvement
291 in thread switching.
292 - Coro::State->is_destroyed is now called is_zombie.
293 - implement a Coro->safe_cancel method that might fail, but
294 cancels in a "safer" way if it succeeds.
295 - add preliminary support for DEBUGGING perls.
296 - get rid of two hash-accesses when initialising a new Coro - this
297 speeds up coro creation by almost a factor of two.
298 - croak when a coro that is being cancelled tries to block
299 (e.g. while executing a guard block), instead of crashing or
300 deadlocking.
301 - use a more robust and also faster method to identify Coro::State
302 objects - speeds up everything a bit.
303 - implement Coro->cancel in XS for a 20% speed improvement, and to
304 be able to implement mutual cancellation.
305 - speed up context switches by a percent or two by more efficiently
306 allocating context stack entries.
307 - implement Coro->join and Coro->on_destroy in XS for a speedup and
308 a reduction in memory use.
309 - cancelling a coro while it itself is cancelling another coro is
310 now supported and working, instead of triggering an assertion.
311 - be a bit more crash-resistant when calling (buggy) on_destroy
312 callbacks (best effort).
313 - move on_destroy into the slf_frame, to allow extension slf
314 functions to have destructors.
315 - get rid if coro refcounting - simply crash in other interpreter
316 threads by nulling the pointers on clone.
317 - simplify warn/die hook handling when loading Coro - the convoluted
318 logic seems to be no longer neccessary.
319 - use libecb instead of our own home-grown gcc hacks.
320 - document alternatives to Coro::LWP. Please use them :)
321 - work around another mindless idiotic NEEDLESS bug in openbsd/mirbsds
322 sigaltstack. Really. wine suffers from it, erlang suffers from it,
323 and it's known since at least 2006.
324
3255.372 Wed Feb 23 06:14:30 CET 2011
326 - apparently mingw doesn't provide a working gettimeofday, try to
327 work around that by relying on Time::HiRes (indirectly brought to
328 my attention by Max Maischein).
329 - fix some portability issues when Time::HiRes was used.
330
3315.371 Mon Feb 21 14:36:08 CET 2011
332 - backport to windows process emulation code again.
333
3345.37 Sat Feb 19 07:49:44 CET 2011
335 - add a big "Coro thread life cycle" section to "man Coro".
336 - try a tentative workaround against the breakage that 5.13 has
337 introduced without depreciation period. sigh.
338 - no longer use Time::HiRes if gettimeofday is available, which
339 saves quite a lot of memory.
340
3415.36 Sun Feb 13 05:33:41 CET 2011
342 - automatically load Coro::Channel, Coro::RWLock, Coro::Semaphore,
343 Coro::SemaphoreSet, Coro::Signal and Coro::Specific on first "new"
344 method call.
345 - undocument Coro::Timer::sleep and obsolete whole module.
346 - optimise Coro::Timer::timeout memory and cpu usage.
347 - slightly updated Coro::Intro for recent changes.
348 - do not initialise PL_dirty anymore.
349
3505.25 Thu Nov 11 01:08:39 CET 2010
351 - try a different approach on netbsd - netbsd 5 finally has marginally
352 working pthreads, but still broken ucontext/sigaltstack.
353 - openbsd 4.8 finally got their act together, Coro works out of the box
354 with asm, setjmp and pthreads (no change, just informational).
355
3565.24 Sat Oct 23 11:27:12 CEST 2010
357 - port to the EV 4.0 API.
358 - work around bugs in mingw32, making strawberry perl work
359 out of the box.
360 - correctly modify Coro::AIO function prototypes
361 so that they reflect the "no optional parameters" rule.
362 - "ported" libcoro to C++.
363
3645.23 Mon May 17 18:50:42 CEST 2010
365 - be more resistant to ordering changes when initialising
366 Coro::AnyEvent, Coro::EV and Coro::Event (reported by Matthias
367 Waldorf).
368 - document that perl 5.12 deliberately removed support for cloning.
369
3705.22 Wed Apr 14 03:55:35 CEST 2010
371 - correctly return udnef on errors in Coro::Handle::read/write
372 (testcase by Marc Mims).
373 - convert Coro::Util into a "perl compatibility wrapper" - the functions
374 are less useful now, but are drop-in replacements for existing
375 functions, listing better alternatives in the documentation. This also
376 fixes a bug in Coro::LWP which naively substituted Socket::inet_aton
377 with Coro::Util::inet_aton.
378 - do not override $Coro::idle unconditionally in Coro.pm, as other
379 modules could have provided their own idle coro already
380 (for exmaple, Coro::AnyEvent).
381 - fix Coro::Util::gethost* functions.
382 - Coro::Timer corretcly exports it's symbols (reported by Hideki Yamamura).
383
3845.21 Wed Dec 16 07:19:51 CET 2009
385 - automatically load Coro::AnyEvent when AnyEvent and Coro are used
386 together.
387 - add some examples on how to combine other event loops with Coro in
388 Coro::AnyEvent, and how to run it (and not to block). Seems to be
389 the most common source of confusion.
390 - try to catch people naively blocking in an event callback.
391 - work around the perl filehandle bug issue in conjunction with
392 older common::sense (as indirectly pointed out by ZSystem).
393 - clarify the "not from signal handlers" section.
394
3955.2 Sun Oct 4 14:54:24 CEST 2009
396 - Coro::Storable destroyed the prototypes of the functions it wrapped.
397 - export rouse_cb and rouse_wait by default now.
398 - fix various prototype mismatches in Coro::AnyEvent and Coro::Handle.
399 - new method $state->swap_sv.
400 - added section on "windows process emulation" to the manpage,
401 after a not-so-fruitful (nor-friendly) "discussion" with chip
402 salzenberg (discussion implies arguments, but his only arguments
403 were ad-hominems, one wonders why he started it in the first
404 place). I hope this explains it well enough for him to understand,
405 and maybe well enough for others to understand.
406 - use common::sense everywhere now.
407 - idle callbacks are no longer supported, use idle coros instead.
408 - print a thread listing when a deadlock is detected.
409
4105.17 Sat Aug 22 23:09:31 CEST 2009
411 - work around a bug in the perl debugger causing crashes
412 when running under the debugger by marking _pool_handler as nodebug.
413 - speed up Coro::async considerably.
414 - try some hacks to get netbsd to work "more often" - their broken
415 setjmp/longjmp, ucontext *and* phtreads are really hard on Coro.
416 - convert Coro to AE 5.0 API.
417
4185.162 Tue Jul 28 04:04:03 CEST 2009
419 - perl 5.8.2 is now minimum requirement.
420 - skip t/19_handle.t on broken windows perls.
421
4225.161 Wed Jul 22 04:47:38 CEST 2009
423 - Coro::AnyEvent::poll could have a different prototype when EV was
424 used as backend (analyzed by Tatsuhiko Miyagawa).
425 - Coro::AnyEvent errornously initialised the event loop when loaded,
426 not on demand.
427 - try to workaround rare */t/01_unblock.t failures.
428
4295.16 Tue Jul 21 01:44:37 CEST 2009
430 - Coro::AnyEvent failed to hook into the event loop
431 when no threads had been readied between detecting
432 the event loop and actually running it.
433 - considerably speed up Coro::Select by taking avdantage
434 of AnyEvent > 4.8 and some other optimisations.
435 - implement paragraph readline mode in Coro::Handle
436 (based on patches by Zsbán Ambrus).
437 - replace WSAEINPROGRESS by WSAEWOULDBLOCK (reported
438 and analyzed by Yasuhiro MATSUMOTO).
439 - clarified libcoro license and copyright.
440 - someone stole my EXTRA_META!!!
441 - implement Coro::Select::patch_pp_sselect and it's brother,
442 for hardcode select overriding.
443
4445.151 Mon Jul 6 05:41:57 CEST 2009
445 - backport to windows process emulation code again (patch by
446 Yasuhiro MATSUMOTO).
447 - slightly update Coro::MakeMaker.
448
4495.15 Tue Jun 30 10:28:06 CEST 2009
450 - deprecate Coro::Socket, document how to get ipv6 support via
451 AnyEvent::Socket instead.
452 - implement signal->wait ($cb) interface, similar to semaphores.
453 - work around SvOK not supporting getmagic, so we have to getmagic
454 to test for undef :/ (reported by Matthias Waldorf).
455 - load Coro::AnyEvent in all modules using AnyEvent.
456 - work around perl corrupting our internal data structures,
457 reported by Tokuhiro Matsuno.
458 - enable per-coroutine real and cpu time gathering
459 (Coro::State::enable_times).
460
4615.14 Wed Jun 24 01:37:48 CEST 2009
462 - provide explicit functions to "cede" to the event loop in Coro::AnyEvent,
463 as this seems to have been a difficult concept (poll, sleep, idle,
464 idle_upto).
465 - add Coro::AnyEvent::readable/writable functions.
466 - clarify Coro::EV/Event/AnyEvent manpages.
467 - free per-thread global scalars in the thread calling ->cancel, to
468 avoid crashes when $_, $@ etc., are magical but some of those
469 had already been freed.
470 - "unexperimentalise" the callback interface for Coro::Semaphore.
471 - speed up ready queue management/context switching by using a linked
472 list instead of an array (~5-10%).
473 - implement "watch" command in Coro::Debug shells.
474 - for fun, implement time-slicing as an example in the manpage.
475 - if AnyEvent detects EV or Event, but we don't have Coro::EV or
476 Coro::Event, use the normal AnyEvent handling instead of dieing
477 (the same is true for Coro::Handle).
478 - properly document Coro::EV::timed_io_once.
479 - avoid unneccessary ->cancel calls in Coro::Handle.
480 - maybe make it work on mingw32 with win32 backend
481 (based on patch by Yasuhiro Matsumoto).
482
4835.132 Fri May 29 09:00:39 CEST 2009
484 - do not keep a reference to the argument itself in
485 Coro::Semaphore::guard, as it could change later.
486 - support SO_RCVBUF/SO_SNDBUF nonstandard Coro::Socket options,
487 should support a prepare callback.
488
4895.131 Mon Mar 16 23:20:37 CET 2009
490 - implement and document Coro->suspend, Coro->resume.
491 - fix Coro::Select implementation to not (often) close
492 the passed file descriptors (testcase provided by pippijn).
493
4945.13 Mon Dec 15 21:51:42 CET 2008
495 - EXPERIMENTAL: implement dynamic winds (on_enter/on_leave).
496 - don't set diehook to C<undef> but instead to NULL, to avoid
497 spurious warnings.
498 - fix a lot of bugs in Coro::SemaphoreSet.
499 - Coro::SemaphoreSet will less often create a semaphore needlessly.
500 - add Coro::SemaphoreSet::count and wait methods.
501 - take advantage of the new Guard module.
502 - deprecate Coro::guard.
503 - try to fix the dreaded 01_unblock tests once more. I hate it when
504 testsuites need more fixing than the code they are supposed to test.
505 - croak in more cases when a required callback isn't resolvable.
506 - fix some minor issues in Coro::State->call/eval.
507 - use current coroutine context instead of a temporary one
508 when temporarily switching to another coroutine.
509 - do not call C-level on_destroy handlers during global destruction,
510 to avoid needless segfaults.
511
5125.12 Sun Dec 7 13:30:38 CET 2008
513 - add default config for MirOS, which seems to be a bug-to-bug
514 compatible fork of openbsd ("world domination by releasing
515 openbsd cvs before the openbsd folks do it" or so :).
516 - free_padlist did destroy the names pad, not good, but didn't
517 seem to bother perl - this could fix issues such as eval ""
518 inside a function called from multiple coroutines.
519 - use a different method to detect destruction time.
520 - be more careful when freeing padlists just before global
521 destruction.
522 - fixed and expanded the call/cc example.
523 - renamed _terminate to _coro_run.
524 - new method Coro::Channel->shutdown.
525 - try pthreads on openbsd <4.4 (broken sigaltstack, will
526 pthreads fare better?).
527 - be less picky about destroying "a" running coroutine.
528
5295.11 Tue Nov 25 21:49:05 CET 2008
530 - DEBUGGING in 5.10.0 is a mess: it constantly flags perfectly
531 working code with failed assertions, introducing more bugs than
532 it fixes, requiring elaborate workarounds :(
