1Revision history for Perl extension Coro. 1Revision history for Perl extension Coro.
2 2
30.06 3TODO: better (earlier) error messages on broken transfer's
4TODO: destroy gets only called on cancel: fix(?)
5TODO: should explore PerlIO::via::CoroCede and PerlIO::via::CoroAIO.
6TODO: maybe implement a default message channel, very much like Erlang
7 (which is cool in a lot of important aspects (failures!),
8 but very lacking in others).
9
103.7
11 - added Coro::Debug, interactive coroutine debugging.
12 - added Coro::Semaphore::adjust.
13 - added Coro::Util::fork_eval.
14 - incompatibly changed Coro::Storable::freeze.
15 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
16 - reduce initial stack sizes to allow for "micro-coroutines".
17
183.63 Wed May 16 14:10:06 CEST 2007
19 - implement handcoded assembly for x86/amd64 SVR ABI.
20
213.62 Fri Apr 27 21:36:06 CEST 2007
22 - upgrade libcoro (which might set unwind info correctly).
23 - change default on linux to setjmp/longjmp.
24
253.61 Thu Apr 19 12:36:18 CEST 2007
26 - Coro::Storable caused an endless loop when thawing invalid
27 pst's sometimes.
28 - use a Semaphore in Coro::Storable, as Storable doesn't
29 seem to be reentrant (although it is documented to
30 be threadsafe...).
31 - fix Coro::Signal to bring back the original unreliable
32 but stateful semantics.
33 - fixed a lot of typos in Coro.pm (patch submitted by David
34 Steinbrunner, which applied flawlessly).
35
363.6 Sat Apr 14 17:13:31 CEST 2007
37 - added some bugfixes to get eg/myhttpd working again.
38 - added Coro::Storable for often-cede'ing freeze/thaw.
39 - try to do a clean exit when a coroutine calls exit
40 (EXPERIMENTAL).
41 - got rid of indirect call through _coro_init.
42 - updated the partly antique examples in eg/ to
43 work again and be a bit less magic, too.
44 - fixed Coro::Signal semantics to work as documented again.
45
463.55 Sun Mar 25 01:20:47 CET 2007
47 - add SAVE_DEFFH to save the default filehandle and enable
48 it by default.
49 - finally move socket-operations from Coro::Socket to Coro::Handle
50 to be able to unblock foreign sockets.
51 - add Coro::State::save_also and guarded_save.
52 - add count accessor to Coro::Semaphore.
53 - add Coro::State::cctx_stacksize.
54 - just for the fun of it, do not rely on implicit context,
55 which can dramatically improve performance, but people
56 using windows-process-emulation perls do not care much about
57 performance.
58
593.51 Sun Mar 4 14:18:04 CET 2007
60 - fixed a problem when you weakened references to Coro::State's
61 (patch by Yuval Kogman).
62
633.501 Wed Feb 28 12:44:07 CET 2007
64 - rename some global symbols as macosx from hell redefines
65 them without asking.
66
673.5 Tue Feb 13 20:22:53 CET 2007
68 - do AnyEvent model detection earlier, avoiding problems
69 caused by first using AnyEvent and later Coro::Event.
70 - implement and document Coro::Event event objects.
71 - fix a potential problem in Coro::Event causing crashes.
72 - initialise PL_comppad when creating a new coroutine,
73 avoids crashes on early coro destruction.
74
753.41 Mon Jan 22 19:19:49 CET 2007
76 - readline on Coro::Handle did not support undefined $/,
77 nor did it deliver partial lines on EOF or error.
78 - implement malloc fallback for stack allocation because
79 stupid broken idiotic OSX has a stupid broken
80 idiotic fits-the-whole-os mmap "implementation" and
81 my dick feels longer if Coro is portable even to
82 obsolete platforms.
83
843.4 Fri Jan 19 21:52:54 CET 2007
85 - remove t/09_timer.t, as it isn't really testing much
86 but was rather flaky in practise.
87 - async_pool coro would keep arguments and callback alive until
88 it was reused.
89 - cancellation of a coroutine could cause spurious idle calls
90 in cede_notself.
91
923.3 Sat Jan 6 03:45:00 CET 2007
93 - implement $coro->on_destroy.
94 - Coro::Event blocking semantics have been changed,
95 documented and - hopefully - improved.
96 - fix nice adding, not subtracting, from priority.
97 - fix ->prio and api_is_ready (patch by Mark Hinds).
98 - fixed an assert ("... == prev__cctx->idle_te")
99 that could errronously trigger.
100 - fix various large and small memleaks.
101 - use a (hopefully) more stable cancel implementation
102 that immediately frees the coroutine data.
103 - cede/cede_notself return a status now.
104 - added Coro::guard function.
105 - added a global coroutine pool for jobs (on my machine,
106 I can create and execute 48k simple coros/s with async,
107 and 128k coros with async_pool).
108 - Coro::AIO now uses the coroutine priority as io priority.
109
1103.2 Fri Dec 22 05:07:09 CET 2006
111 - improve portability to slightly older perls.
112 - use cleaner coroutine destruction.
113 - simplify configuration for users.
114 - optionally (unrecommended) prefer perl functions over
115 their coro replacements.
116
1173.11 Tue Dec 5 13:11:24 CET 2006
118 - fixed some bogus assert's, but as perl.h disables assert even
119 without NDEBUG (thank you very much), not too many people should
120 notice (that did include myself). Andreas König noticed, though :)
121 - do not save/restore PL_sortcxix on >= 5.9.x, it doesn't seem to have
122 it. Also noticed by Andreas König :)
123 - save/restore tainted status.
124 - verified to pass the testsuite on my 5.9.5.
125
1263.1 Mon Dec 4 23:03:40 CET 2006
127 - INCOMPATIBLE CHANGE: $/ is now per-coroutine (but slow).
128 - incompatible change: transfer flags are now per-state.
129 - give a better error message on deadlock.
130 - document Coro::nready.
131 - enhanced testsuite.
132
1333.01 Sun Dec 3 23:47:42 CET 2006
134 - forgot to include Coro::Timer.
135
1363.0 Sun Dec 3 22:57:25 CET 2006
137 - the "FINALLY COMPLETELY STABLE" release (coming soon:
138 the "FAMOUS LAST WORDS" release).
139 - implement a new stack sharing algorithm, which uses a stack
140 pool (size currently hardcoded).
141 - make stack sharing mandatory (it no longer uses a heuristic).
142 - eval/die no longer cause weird problems under heavy use.
143 - Coro::Event could cause livelocks if it was used but
144 no Coro::Event watchers were used.
145 - Coro::Event now uses asynccheck as prepare does not
146 check for changed watchers.
147 - Coro::Event allows multiple waiting coros and will wake up one
148 per event.
149 - Coro::Event should be cleaner and more efficient now.
150 - new utility function Coro::unblock_sub.
151 - document the sad fact that Event is no longer reentrant.
152 - putting a coroutine into the ready queue twice could under
153 some circumstances lead to stack corruption.
154 - minor incompatibility: subclassing Coro::State is supported
155 directly now without going through a _coro_state member.
156 - state/coro switching is much faster now.
157 - very minor optimisations and code/documentation cleanup.
158 - avoid problems due to compiler inlining.
159 - removed timers from Coro::Timer -> use AnyEvent instead.
160 - replaced Coro::idle coroutine by (cleaner) idle handler.
161 - updated to newest libcoro.
162 - implement enhanced support for valgrind.
163 - implement is_ready and return value for ready.
164 - removed Coro::Cont, it was a misnomer (it's generators),
165 and it was somewhat annoying to get it right. Will come back
166 if somebody asks for it :)
167 - many ->wait methods and Coro::Event could return
168 spuriously without the event having happened.
169
1702.5 Tue Nov 7 12:22:33 CET 2006
171 - made Coro::Util, Coro::Select, Coro::Handle and Coro::Socket
172 use AnyEvent, moved them to Coro/.
173 - added Coro::LWP which contains all the uglyness required to
174 make LWP non-blocking.
175 - should work with perl 5.9.x now (Andreas König made me do it).
176 - fixed another bug in Coro::Select when the timeout was undef.
177 - reuse PL_start_env for all coros, saves some memory per coroutine.
178 - manage PL_top_env differently, hopefully to avoid panic: top_env.
179 - timeout argument was not properly used in Coro::Socket.
180 - allow limited forms of subclassing in Coro::Handle/Coro::Socket.
181 - emulate undocumented(!) functionality of IO::Socket required
182 by LWP(!!).
183 - updated eg/lwp to work with newer lwp's.
184 - remove "FATAL: uncaught exception" prefix. Coroutines that die
185 kill the whole process, just as exceptions in the main "coroutine"
186 did already.
187
1882.1 Wed Nov 1 23:01:13 CET 2006
189 - fix a long-standing bug in Coro::Select where select with
190 zero timeout would instead change the current default filehandle.
191 - use a simpler and hopefully more robust way to clone padlists
192 (uses less memory and a perl function instead of our own).
193 - coro can now create a stack guard area on many architectures.
194 - Coro::AIO properly reexports additional functions from IO::AIO.
195 - updated libcoro with a workaround for OS X,
196 pach and testing by Michael Schwern.
197
1982.0 Tue Oct 24 05:47:17 CEST 2006
199 - support additional aio requests in Coro::AIO.
200
2011.9 (never properly released due to a glitch)
202
2031.8 Thu Feb 2 00:59:06 CET 2006
204 - applied suggested patch by SAMV to avoid problems during stupid
205 mark & sweep gc run.
206 - applied patch by Scott Walters for 5.9.3 compatibility.
207
2081.7 Tue Dec 27 01:41:58 CET 2005
209 - added Coro::AIO, a thin wrapper around IO::AIO.
210 - improved Makefile.PL explanations.
211
2121.6 Mon Dec 12 21:30:05 CET 2005
213 - additionally save PM_curpm might fix as-of-yet
214 unseen problems with regex matches being attributed to the
215 wrong package.
216 - add t/10_bugs.t, which currently checks against imho broken
217 perls that use 0.26MB of stack space per Perl_magic_get
218 invocation (newer linuxes) as opposed to the 0.0002MB perl
219 normally uses.
220 - make stacksize configurable for the ultimate debian experience.
221
2221.51 Mon Dec 12 18:48:36 CET 2005
223 - remove debugging warn() accidentally left in Coro::Select.
224
2251.5 Tue Nov 29 13:32:44 CET 2005
226 - use Coro::Event inside Coro::Select to avoid spurious deadlocks.
227 - fix Coro::Select 'select'.
228 - strict'ify some modules.
229 - libcoro errornously restored the SIGUSR2 handler to SIGUSR1.
230 - use XSLoader in selected modules.
231 - remove some 5.6 compatibility cruft.
232
2331.4 Tue Sep 6 00:11:05 CEST 2005
234 - libcoro did not take into account the trampoline on amd64,
235 when 'l'inux method was used.
236
2371.31 Tue Aug 30 23:31:33 CEST 2005
238 - some portability fixes/workarounds.
239
2401.3 Sat Aug 20 03:08:56 CEST 2005
241 - no code changes. module seems to work fine.
242 - improve Coro::State docs, remove reference to nonexisting
243 Coro::State::flush method.
244 - no longer autodetect windows, present it as an option instead.
245
2461.2 Mon May 16 02:00:55 CEST 2005
247 - included libcoro.c earlier in State.xs, might improve portability.
248 - use a faster and possibly more stable Coro::Cont implementation.
249 - accept x86_64 in addition to amd64 for optimized linux-amd64 support.
250 - fix bugs Coro::SemaphoreSet that could cause locks never to be freed.
251 - fix bugs in CoroAPI.h and document it in Coro::MakeMaker.
252
2531.11 Thu Mar 3 18:00:52 CET 2005
254 - change of contact address.
255
2561.1 Tue Feb 22 20:51:16 CET 2005
257 - support [l]inux method on amd64.
258 - allow some context switches while compiling/eval'ing.
259
2601.0 Tue Aug 10 03:47:27 CEST 2004
261 - Event 0.89 fixes the bug again.
262 - fix the remaining(??) memleak. I didn't free the cache-AV for
263 padlists, so one AV per created anon-sub leaked.
264
2650.97 Fri May 14 15:23:32 CEST 2004
266 - remove stupid gcc extension that was an experiment only anyway.
267
2680.96 Thu May 13 18:09:29 CEST 2004
269 - tell people if they have yet another broken Event variant.
270 - made Coro to work _better_ with threads (it seems that, as long
271 as you use Coros in one thread only everything will work fine.
272 Looking at the perl source the problem might be missing locking
273 between Coro and some perl internal routines. That's not easily
274 fixable).
275 - (hopefully) got rid of the static xnext inside transfer.
276
2770.95 Sun Feb 15 03:20:28 CET 2004
278 - removed Coro::State::flush, implemented a new and much
279 faster caching mechanism by attaching magic to the CV.
280 - a memleak with (real) closures remains.
281 - dramatically reduced size of stacks to 65536 (linux/x86), after
282 observing that even myhttpd never had more than a kilobyte
283 of stack in use (stack is still only physically allocated in
284 pagesize increments for systems suporting mmap).
285 - fix for a "cygwin-64" architecture added, proposed by Stefan Traby.
286 - fix for threaded perl.
287
2880.9 Sun Nov 23 04:32:39 CET 2003
289 - fix a few very hard to track down but (of course) stupid
290 memory leaks.
291 - stringify version number to avoid locale problems :(.
292 - perl 5.9.0 does not have SvPADBUSY, reported by Scott Walters,
293 hopefully ignoring it "just works".
294
2950.8 Wed Nov 5 19:38:40 CET 2003
296 - port to perl5.005_03, but only 5.8.x+ is supported!
297 - honor LocalAddr even without LocalPort in Coro::Socket.
298
2990.7 Tue May 27 03:12:38 CEST 2003
300 - the version jump indicates some level of testing, not gobs
301 of new features.
302 - uh... I found the prompt function in ExtUtils::MakeMaker.
303 Highly correct stuff, that is...
304 - fixed(?) a bug with die's in coroutines causing "panic: top_env".
305 the fix is not well understood by the author, so beware :(.
306
3070.652 Thu May 8 02:54:46 CEST 2003
308 - Applied patch by Slaven Rezic to set default to "s" on FreeBSD,
309 cause version 4 doesn't have ucontext.
310 - Benjamin Reed reported that setjmp works fine on darwin,
311 so preselect it.
312
3130.651 Sat Mar 29 15:00:23 CET 2003
314 - fix a bug in Coro::Handle where some bytes could get lost
315 on reading, reported by jason@nichego.net.
316
3170.65 Sun Mar 23 00:08:26 CET 2003
318 - added a README.linux-glibc.
319 - new module Coro::Select.
320 - also save/restore PL_comppad, fixes segfaults with 5.8.1.
321 (I never claimed that I know what I am doing ;).
322 - set default to setjmp/longjmp on non-x86-linux.
323
3240.6 Thu Nov 21 11:09:06 CET 2002
325 - made lazy context switching the default.
326 - fixed the bug where SemaphoreSet::guard
327 was the same as timed_guard and timed_guard was missing.
328 - fix a memleak in Coro::Timer.
329 - reclassified context sharing as not experimental.
330
3310.534 Sun Apr 14 03:05:12 CEST 2002
332 - fixed backspace => tab in header parsing (myhttpd).
333 - added eg/readline, for elmex.
334 - Coro::Event now calls ->start on first call instead of
335 ->again, which created wrong timeouts for the first ->next.
336 - fixed a bug where Coro::Socket returned a closed socket instead
337 of nothing on ECONNREFUSED and similar error conditions.
338
3390.533 Mon Feb 18 18:49:40 CET 2002
340 - adapt to finally working Event-0.85.
341 - fixed buggy event initialization (trapped under windows, but how
342 could it possibly have worked anywhere?)
343
3440.532 Wed Jan 16 02:45:32 CET 2002
345 - removed the reference to pp_entersub, might work on
346 (some) win32 perls now (testsuite works under cygwin,
347 without Event, which freezes).
348
3490.531 Mon Dec 10 22:18:44 CET 2001
350 - Fixed a bug in SemaphoreSet::timed_down.
351
3520.53 Tue Nov 27 21:11:13 CET 2001
353 - some tests for Event.
354 - slightly different internal architecture to get refcnt into the object
355 and not the reference. might fix a few bugs, certainly did introduce
356 new ones.
357 - Coro::Timer (independent of Event).
358 - new timed_wait functions for Coro::Signal, Semaphore, SemaphoreSet.
359
3600.52 Tue Nov 6 21:36:18 CET 2001
361 - ported to cygwin (trivial).
362 patch by Gerrit P. Haase <gp@familiehaase.de>.
363 - small setjmp code fix by Sullivan.DanielJ@epamail.epa.gov.
364
3650.51 Thu Nov 1 20:39:01 CET 2001
366 - terminate/cancel now work properly (otherwise termination
367 could cause a "next coroutine is not and contains not..."
368 error.
369 - added Coro::Socket::shutdown.
370 - Coro::Event::loop no is the same as Event::loop.
371 - implemented terminate with args + join.
372
3730.5 Fri Sep 28 16:15:35 CEST 2001
374 - fixed "print" on a Coro::Handle. The print method worked.
375 - small tweaks (seem to reduce memory consumption a lot)
376 in various modules.
377 - splendid use of "no warnings" scattered throughout.
378 - added Coro::Handle::rbuf, fixed Coro::Handle::fh.
379
3800.49 Sun Sep 16 02:42:45 CEST 2001
381 - changed some method calls to function calls for speed
382 inside Coro::Handle.
383 - make Coro::Handle use an array instead of a hash for
384 speed reasons.
385 - IRIX mystery solved: it's SGI's NT, after all: "standard, huh?".
386 sjlj and ucontext should now work.
387 - IRIX-specific port for libcoro.
388 - swapped order of accept results to match IO::Socket.
389 - changed getsock/peername to sock/peername to match IO::Socket.
390 - fixed a bug that caused segfault when returning to main task
391 under some circumstances.
392 - other bugfixes.
393
3940.45 Sun Sep 2 02:54:01 CEST 2001
395 - new method Coro::Handle::timeout.
396 - corrected speling of set...name to get...name in Coro::Socket.
397 - Coro::Socket::accept now returns a Coro::Socket, not a Coro::Handle.
398 - Coro::Handle now supports fileno and FILENO.
399 - added eg/myhttpd, a web server.
400 - Coro::Socket now accepts numeric ports as well as "port(number)"
401 syntax.
402 - moved some scheduling primitives into xs code. more to come.
403 - new simple priority system.
404 - implemented Coro::Event using XS, almost four times faster!
405 - small memory corruption problem fixed (boy that was difficult).
406
4070.13 Wed Aug 8 16:53:07 CEST 2001
408 - new method Coro::Handle::readline.
409 - added eg/lwp and Coro::Handle::autoflush, to make LWP work.
410 (see eg/lwp on how to make LWP non-blocking).
411 - renamed Coro::Socket::new_inet to new.
412 - added Coro::Util, some utility functions.
413 - die/eval now works better (still get annoying (but true ;)
414 "Callback called exit" messages).
415 - Coro::Handle now supports timeout, and Coro::Socket Timeout.
416 - much better Coro::Socket support.
417
4180.12 Fri Jul 27 04:19:01 CEST 2001
419 - do not use mmap if neither MAP_ANON nor MAP_ANONYMOUS is defined.
420 - very experimental stack sharing algorithm. not 100% safe but
421 should work well in practise ;)
422 - added Coro::RWLock.
423 - Coro::Specific now works.
424
4250.11 Tue Jul 24 22:49:21 CEST 2001
426 - added specialized hack for newer and older linux versions (fast).
427 - renamed Coro::Event::IO to Coro::Handle.
428 - new module Coro::Socket.
429
4300.1 Tue Jul 24 01:47:53 CEST 2001
431 - release candidate 3. A rather new internal structure :(
432 - the great renaming: Damian Conway gave me a suitable replacement
433 for yield.
434 - added Coro/libcoro, a portable coroutine implementation for C
435 (not even perl-dependent!!!), which can be used by Coro::State.
436 - renamed SAVE_DEFSV (on xs-level only) to avoid symbol clash in
437 perl-5.6.
438 - new function Coro::Event::idle.
439 - the idle process is now overriden
440 by default in Coro::Event.
441 - Coro::Channel now enforces the size.
442 - canceling events now works in all cases.
443 - Coro state now include $_ and $@.
444 - yet another bug workaround that I do not really understand :(
445 - new module Coro::Event::IO (very undocumented) to do
446 non-blocking i/o.
447 - performance tuning.
448
4490.08 Thu Jul 19 06:13:25 CEST 2001
450 - release candidate 2 (new functionality).
451 - add Coro::State::flush function.
452 - transfer now supports a flags value (mostly for speed ATM).
453 - might compile and work in the presence of threads now.
454 - continuations have a saner syntax.
455 - no more memleaks.
456
4570.07 Tue Jul 17 17:40:18 CEST 2001
458 - release candidate 1 ;)
459 - slightly nicer code.
460 - fixed a scheduling bug in Coro::Event.
461
4620.06 Tue Jul 17 04:23:24 CEST 2001
