1Revision history for Perl extension Coro. 1Revision history for Perl extension Coro.
2 2
30.5 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).

103.62 Fri Apr 27 21:36:06 CEST 2007
11 - upgrade libcoro (which might set unwind info correctly).
12 - change default on linux to setjmp/longjmp.
13
143.61 Thu Apr 19 12:36:18 CEST 2007
15 - Coro::Storable caused an endless loop when thawing invalid
16 pst's sometimes.
17 - use a Semaphore in Coro::Storable, as Storable doesn't
18 seem to be reentrant (although it is documented to
19 be threadsafe...).
20 - fix Coro::Signal to bring back the original unreliable
21 but stateful semantics.
22 - fixed a lot of typos in Coro.pm (patch submitted by David
23 Steinbrunner, which applied flawlessly).
24
253.6 Sat Apr 14 17:13:31 CEST 2007
26 - added some bugfixes to get eg/myhttpd working again.
27 - added Coro::Storable for often-cede'ing freeze/thaw.
28 - try to do a clean exit when a coroutine calls exit
29 (EXPERIMENTAL).
30 - got rid of indirect call through _coro_init.
31 - updated the partly antique examples in eg/ to
32 work again and be a bit less magic, too.
33 - fixed Coro::Signal semantics to work as documented again.
34
353.55 Sun Mar 25 01:20:47 CET 2007
36 - add SAVE_DEFFH to save the default filehandle and enable
37 it by default.
38 - finally move socket-operations from Coro::Socket to Coro::Handle
39 to be able to unblock foreign sockets.
40 - add Coro::State::save_also and guarded_save.
41 - add count accessor to Coro::Semaphore.
42 - add Coro::State::cctx_stacksize.
43 - just for the fun of it, do not rely on implicit context,
44 which can dramatically improve performance, but people
45 using windows-process-emulation perls do not care much about
46 performance.
47
483.51 Sun Mar 4 14:18:04 CET 2007
49 - fixed a problem when you weakened references to Coro::State's
50 (patch by Yuval Kogman).
51
523.501 Wed Feb 28 12:44:07 CET 2007
53 - rename some global symbols as macosx from hell redefines
54 them without asking.
55
563.5 Tue Feb 13 20:22:53 CET 2007
57 - do AnyEvent model detection earlier, avoiding problems
58 caused by first using AnyEvent and later Coro::Event.
59 - implement and document Coro::Event event objects.
60 - fix a potential problem in Coro::Event causing crashes.
61 - initialise PL_comppad when creating a new coroutine,
62 avoids crashes on early coro destruction.
63
643.41 Mon Jan 22 19:19:49 CET 2007
65 - readline on Coro::Handle did not support undefined $/,
66 nor did it deliver partial lines on EOF or error.
67 - implement malloc fallback for stack allocation because
68 stupid broken idiotic OSX has a stupid broken
69 idiotic fits-the-whole-os mmap "implementation" and
70 my dick feels longer if Coro is portable even to
71 obsolete platforms.
72
733.4 Fri Jan 19 21:52:54 CET 2007
74 - remove t/09_timer.t, as it isn't really testing much
75 but was rather flaky in practise.
76 - async_pool coro would keep arguments and callback alive until
77 it was reused.
78 - cancellation of a coroutine could cause spurious idle calls
79 in cede_notself.
80
813.3 Sat Jan 6 03:45:00 CET 2007
82 - implement $coro->on_destroy.
83 - Coro::Event blocking semantics have been changed,
84 documented and - hopefully - improved.
85 - fix nice adding, not subtracting, from priority.
86 - fix ->prio and api_is_ready (patch by Mark Hinds).
87 - fixed an assert ("... == prev__cctx->idle_te")
88 that could errronously trigger.
89 - fix various large and small memleaks.
90 - use a (hopefully) more stable cancel implementation
91 that immediately frees the coroutine data.
92 - cede/cede_notself return a status now.
93 - added Coro::guard function.
94 - added a global coroutine pool for jobs (on my machine,
95 I can create and execute 48k simple coros/s with async,
96 and 128k coros with async_pool).
97 - Coro::AIO now uses the coroutine priority as io priority.
98
993.2 Fri Dec 22 05:07:09 CET 2006
100 - improve portability to slightly older perls.
101 - use cleaner coroutine destruction.
102 - simplify configuration for users.
103 - optionally (unrecommended) prefer perl functions over
104 their coro replacements.
105
1063.11 Tue Dec 5 13:11:24 CET 2006
107 - fixed some bogus assert's, but as perl.h disables assert even
108 without NDEBUG (thank you very much), not too many people should
109 notice (that did include myself). Andreas König noticed, though :)
110 - do not save/restore PL_sortcxix on >= 5.9.x, it doesn't seem to have
111 it. Also noticed by Andreas König :)
112 - save/restore tainted status.
113 - verified to pass the testsuite on my 5.9.5.
114
1153.1 Mon Dec 4 23:03:40 CET 2006
116 - INCOMPATIBLE CHANGE: $/ is now per-coroutine (but slow).
117 - incompatible change: transfer flags are now per-state.
118 - give a better error message on deadlock.
119 - document Coro::nready.
120 - enhanced testsuite.
121
1223.01 Sun Dec 3 23:47:42 CET 2006
123 - forgot to include Coro::Timer.
124
1253.0 Sun Dec 3 22:57:25 CET 2006
126 - the "FINALLY COMPLETELY STABLE" release (coming soon:
127 the "FAMOUS LAST WORDS" release).
128 - implement a new stack sharing algorithm, which uses a stack
129 pool (size currently hardcoded).
130 - make stack sharing mandatory (it no longer uses a heuristic).
131 - eval/die no longer cause weird problems under heavy use.
132 - Coro::Event could cause livelocks if it was used but
133 no Coro::Event watchers were used.
134 - Coro::Event now uses asynccheck as prepare does not
135 check for changed watchers.
136 - Coro::Event allows multiple waiting coros and will wake up one
137 per event.
138 - Coro::Event should be cleaner and more efficient now.
139 - new utility function Coro::unblock_sub.
140 - document the sad fact that Event is no longer reentrant.
141 - putting a coroutine into the ready queue twice could under
142 some circumstances lead to stack corruption.
143 - minor incompatibility: subclassing Coro::State is supported
144 directly now without going through a _coro_state member.
145 - state/coro switching is much faster now.
146 - very minor optimisations and code/documentation cleanup.
147 - avoid problems due to compiler inlining.
148 - removed timers from Coro::Timer -> use AnyEvent instead.
149 - replaced Coro::idle coroutine by (cleaner) idle handler.
150 - updated to newest libcoro.
151 - implement enhanced support for valgrind.
152 - implement is_ready and return value for ready.
153 - removed Coro::Cont, it was a misnomer (it's generators),
154 and it was somewhat annoying to get it right. Will come back
155 if somebody asks for it :)
156 - many ->wait methods and Coro::Event could return
157 spuriously without the event having happened.
158
1592.5 Tue Nov 7 12:22:33 CET 2006
160 - made Coro::Util, Coro::Select, Coro::Handle and Coro::Socket
161 use AnyEvent, moved them to Coro/.
162 - added Coro::LWP which contains all the uglyness required to
163 make LWP non-blocking.
164 - should work with perl 5.9.x now (Andreas König made me do it).
165 - fixed another bug in Coro::Select when the timeout was undef.
166 - reuse PL_start_env for all coros, saves some memory per coroutine.
167 - manage PL_top_env differently, hopefully to avoid panic: top_env.
168 - timeout argument was not properly used in Coro::Socket.
169 - allow limited forms of subclassing in Coro::Handle/Coro::Socket.
170 - emulate undocumented(!) functionality of IO::Socket required
171 by LWP(!!).
172 - updated eg/lwp to work with newer lwp's.
173 - remove "FATAL: uncaught exception" prefix. Coroutines that die
174 kill the whole process, just as exceptions in the main "coroutine"
175 did already.
176
1772.1 Wed Nov 1 23:01:13 CET 2006
178 - fix a long-standing bug in Coro::Select where select with
179 zero timeout would instead change the current default filehandle.
180 - use a simpler and hopefully more robust way to clone padlists
181 (uses less memory and a perl function instead of our own).
182 - coro can now create a stack guard area on many architectures.
183 - Coro::AIO properly reexports additional functions from IO::AIO.
184 - updated libcoro with a workaround for OS X,
185 pach and testing by Michael Schwern.
186
1872.0 Tue Oct 24 05:47:17 CEST 2006
188 - support additional aio requests in Coro::AIO.
189
1901.9 (never properly released due to a glitch)
191
1921.8 Thu Feb 2 00:59:06 CET 2006
193 - applied suggested patch by SAMV to avoid problems during stupid
194 mark & sweep gc run.
195 - applied patch by Scott Walters for 5.9.3 compatibility.
196
1971.7 Tue Dec 27 01:41:58 CET 2005
198 - added Coro::AIO, a thin wrapper around IO::AIO.
199 - improved Makefile.PL explanations.
200
2011.6 Mon Dec 12 21:30:05 CET 2005
202 - additionally save PM_curpm might fix as-of-yet
203 unseen problems with regex matches being attributed to the
204 wrong package.
205 - add t/10_bugs.t, which currently checks against imho broken
206 perls that use 0.26MB of stack space per Perl_magic_get
207 invocation (newer linuxes) as opposed to the 0.0002MB perl
208 normally uses.
209 - make stacksize configurable for the ultimate debian experience.
210
2111.51 Mon Dec 12 18:48:36 CET 2005
212 - remove debugging warn() accidentally left in Coro::Select.
213
2141.5 Tue Nov 29 13:32:44 CET 2005
215 - use Coro::Event inside Coro::Select to avoid spurious deadlocks.
216 - fix Coro::Select 'select'.
217 - strict'ify some modules.
218 - libcoro errornously restored the SIGUSR2 handler to SIGUSR1.
219 - use XSLoader in selected modules.
220 - remove some 5.6 compatibility cruft.
221
2221.4 Tue Sep 6 00:11:05 CEST 2005
223 - libcoro did not take into account the trampoline on amd64,
224 when 'l'inux method was used.
225
2261.31 Tue Aug 30 23:31:33 CEST 2005
227 - some portability fixes/workarounds.
228
2291.3 Sat Aug 20 03:08:56 CEST 2005
230 - no code changes. module seems to work fine.
231 - improve Coro::State docs, remove reference to nonexisting
232 Coro::State::flush method.
233 - no longer autodetect windows, present it as an option instead.
234
2351.2 Mon May 16 02:00:55 CEST 2005
236 - included libcoro.c earlier in State.xs, might improve portability.
237 - use a faster and possibly more stable Coro::Cont implementation.
238 - accept x86_64 in addition to amd64 for optimized linux-amd64 support.
239 - fix bugs Coro::SemaphoreSet that could cause locks never to be freed.
240 - fix bugs in CoroAPI.h and document it in Coro::MakeMaker.
241
2421.11 Thu Mar 3 18:00:52 CET 2005
243 - change of contact address.
244
2451.1 Tue Feb 22 20:51:16 CET 2005
246 - support [l]inux method on amd64.
247 - allow some context switches while compiling/eval'ing.
248
2491.0 Tue Aug 10 03:47:27 CEST 2004
250 - Event 0.89 fixes the bug again.
251 - fix the remaining(??) memleak. I didn't free the cache-AV for
252 padlists, so one AV per created anon-sub leaked.
253
2540.97 Fri May 14 15:23:32 CEST 2004
255 - remove stupid gcc extension that was an experiment only anyway.
256
2570.96 Thu May 13 18:09:29 CEST 2004
258 - tell people if they have yet another broken Event variant.
259 - made Coro to work _better_ with threads (it seems that, as long
260 as you use Coros in one thread only everything will work fine.
261 Looking at the perl source the problem might be missing locking
262 between Coro and some perl internal routines. That's not easily
263 fixable).
264 - (hopefully) got rid of the static xnext inside transfer.
265
2660.95 Sun Feb 15 03:20:28 CET 2004
267 - removed Coro::State::flush, implemented a new and much
268 faster caching mechanism by attaching magic to the CV.
269 - a memleak with (real) closures remains.
270 - dramatically reduced size of stacks to 65536 (linux/x86), after
271 observing that even myhttpd never had more than a kilobyte
272 of stack in use (stack is still only physically allocated in
273 pagesize increments for systems suporting mmap).
274 - fix for a "cygwin-64" architecture added, proposed by Stefan Traby.
275 - fix for threaded perl.
276
2770.9 Sun Nov 23 04:32:39 CET 2003
278 - fix a few very hard to track down but (of course) stupid
279 memory leaks.
280 - stringify version number to avoid locale problems :(.
281 - perl 5.9.0 does not have SvPADBUSY, reported by Scott Walters,
282 hopefully ignoring it "just works".
283
2840.8 Wed Nov 5 19:38:40 CET 2003
285 - port to perl5.005_03, but only 5.8.x+ is supported!
286 - honor LocalAddr even without LocalPort in Coro::Socket.
287
2880.7 Tue May 27 03:12:38 CEST 2003
289 - the version jump indicates some level of testing, not gobs
290 of new features.
291 - uh... I found the prompt function in ExtUtils::MakeMaker.
292 Highly correct stuff, that is...
293 - fixed(?) a bug with die's in coroutines causing "panic: top_env".
294 the fix is not well understood by the author, so beware :(.
295
2960.652 Thu May 8 02:54:46 CEST 2003
297 - Applied patch by Slaven Rezic to set default to "s" on FreeBSD,
298 cause version 4 doesn't have ucontext.
299 - Benjamin Reed reported that setjmp works fine on darwin,
300 so preselect it.
301
3020.651 Sat Mar 29 15:00:23 CET 2003
303 - fix a bug in Coro::Handle where some bytes could get lost
304 on reading, reported by jason@nichego.net.
305
3060.65 Sun Mar 23 00:08:26 CET 2003
307 - added a README.linux-glibc.
308 - new module Coro::Select.
309 - also save/restore PL_comppad, fixes segfaults with 5.8.1.
310 (I never claimed that I know what I am doing ;).
311 - set default to setjmp/longjmp on non-x86-linux.
312
3130.6 Thu Nov 21 11:09:06 CET 2002
314 - made lazy context switching the default.
315 - fixed the bug where SemaphoreSet::guard
316 was the same as timed_guard and timed_guard was missing.
317 - fix a memleak in Coro::Timer.
318 - reclassified context sharing as not experimental.
319
3200.534 Sun Apr 14 03:05:12 CEST 2002
321 - fixed backspace => tab in header parsing (myhttpd).
322 - added eg/readline, for elmex.
323 - Coro::Event now calls ->start on first call instead of
324 ->again, which created wrong timeouts for the first ->next.
325 - fixed a bug where Coro::Socket returned a closed socket instead
326 of nothing on ECONNREFUSED and similar error conditions.
327
3280.533 Mon Feb 18 18:49:40 CET 2002
329 - adapt to finally working Event-0.85.
330 - fixed buggy event initialization (trapped under windows, but how
331 could it possibly have worked anywhere?)
332
3330.532 Wed Jan 16 02:45:32 CET 2002
334 - removed the reference to pp_entersub, might work on
335 (some) win32 perls now (testsuite works under cygwin,
336 without Event, which freezes).
337
3380.531 Mon Dec 10 22:18:44 CET 2001
339 - Fixed a bug in SemaphoreSet::timed_down.
340
3410.53 Tue Nov 27 21:11:13 CET 2001
342 - some tests for Event.
343 - slightly different internal architecture to get refcnt into the object
344 and not the reference. might fix a few bugs, certainly did introduce
345 new ones.
346 - Coro::Timer (independent of Event).
347 - new timed_wait functions for Coro::Signal, Semaphore, SemaphoreSet.
348
3490.52 Tue Nov 6 21:36:18 CET 2001
350 - ported to cygwin (trivial).
351 patch by Gerrit P. Haase <gp@familiehaase.de>.
352 - small setjmp code fix by Sullivan.DanielJ@epamail.epa.gov.
353
3540.51 Thu Nov 1 20:39:01 CET 2001
355 - terminate/cancel now work properly (otherwise termination
356 could cause a "next coroutine is not and contains not..."
357 error.
358 - added Coro::Socket::shutdown.
359 - Coro::Event::loop no is the same as Event::loop.
360 - implemented terminate with args + join.
361
3620.5 Fri Sep 28 16:15:35 CEST 2001
363 - fixed "print" on a Coro::Handle. The print method worked.
364 - small tweaks (seem to reduce memory consumption a lot)
365 in various modules.
366 - splendid use of "no warnings" scattered throughout.
367 - added Coro::Handle::rbuf, fixed Coro::Handle::fh.
4 368
50.49 Sun Sep 16 02:42:45 CEST 2001 3690.49 Sun Sep 16 02:42:45 CEST 2001
6 - changed some method calls to function calls for speed 370 - changed some method calls to function calls for speed
7 inside Coro::Handle. 371 inside Coro::Handle.
8 - make Coro::Handle use an array instead of a hash for 372 - make Coro::Handle use an array instead of a hash for
