1Revision history for Perl extension Coro. 1Revision history for Perl extension Coro.
2 2
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
10 - implement handcoded assembly for x86/amd64 SVR ABI.
11
123.62 Fri Apr 27 21:36:06 CEST 2007
13 - upgrade libcoro (which might set unwind info correctly).
14 - change default on linux to setjmp/longjmp.
15
163.61 Thu Apr 19 12:36:18 CEST 2007
17 - Coro::Storable caused an endless loop when thawing invalid
18 pst's sometimes.
19 - use a Semaphore in Coro::Storable, as Storable doesn't
20 seem to be reentrant (although it is documented to
21 be threadsafe...).
22 - fix Coro::Signal to bring back the original unreliable
23 but stateful semantics.
24 - fixed a lot of typos in Coro.pm (patch submitted by David
25 Steinbrunner, which applied flawlessly).
26
273.6 Sat Apr 14 17:13:31 CEST 2007
28 - added some bugfixes to get eg/myhttpd working again.
29 - added Coro::Storable for often-cede'ing freeze/thaw.
30 - try to do a clean exit when a coroutine calls exit
31 (EXPERIMENTAL).
32 - got rid of indirect call through _coro_init.
33 - updated the partly antique examples in eg/ to
34 work again and be a bit less magic, too.
35 - fixed Coro::Signal semantics to work as documented again.
36
373.55 Sun Mar 25 01:20:47 CET 2007
38 - add SAVE_DEFFH to save the default filehandle and enable
39 it by default.
40 - finally move socket-operations from Coro::Socket to Coro::Handle
41 to be able to unblock foreign sockets.
42 - add Coro::State::save_also and guarded_save.
43 - add count accessor to Coro::Semaphore.
44 - add Coro::State::cctx_stacksize.
45 - just for the fun of it, do not rely on implicit context,
46 which can dramatically improve performance, but people
47 using windows-process-emulation perls do not care much about
48 performance.
49
503.51 Sun Mar 4 14:18:04 CET 2007
51 - fixed a problem when you weakened references to Coro::State's
52 (patch by Yuval Kogman).
53
543.501 Wed Feb 28 12:44:07 CET 2007
55 - rename some global symbols as macosx from hell redefines
56 them without asking.
57
583.5 Tue Feb 13 20:22:53 CET 2007
59 - do AnyEvent model detection earlier, avoiding problems
60 caused by first using AnyEvent and later Coro::Event.
61 - implement and document Coro::Event event objects.
62 - fix a potential problem in Coro::Event causing crashes.
63 - initialise PL_comppad when creating a new coroutine,
64 avoids crashes on early coro destruction.
65
663.41 Mon Jan 22 19:19:49 CET 2007
67 - readline on Coro::Handle did not support undefined $/,
68 nor did it deliver partial lines on EOF or error.
69 - implement malloc fallback for stack allocation because
70 stupid broken idiotic OSX has a stupid broken
71 idiotic fits-the-whole-os mmap "implementation" and
72 my dick feels longer if Coro is portable even to
73 obsolete platforms.
74
753.4 Fri Jan 19 21:52:54 CET 2007
76 - remove t/09_timer.t, as it isn't really testing much
77 but was rather flaky in practise.
78 - async_pool coro would keep arguments and callback alive until
79 it was reused.
80 - cancellation of a coroutine could cause spurious idle calls
81 in cede_notself.
82
833.3 Sat Jan 6 03:45:00 CET 2007
84 - implement $coro->on_destroy.
85 - Coro::Event blocking semantics have been changed,
86 documented and - hopefully - improved.
87 - fix nice adding, not subtracting, from priority.
88 - fix ->prio and api_is_ready (patch by Mark Hinds).
89 - fixed an assert ("... == prev__cctx->idle_te")
90 that could errronously trigger.
91 - fix various large and small memleaks.
92 - use a (hopefully) more stable cancel implementation
93 that immediately frees the coroutine data.
94 - cede/cede_notself return a status now.
95 - added Coro::guard function.
96 - added a global coroutine pool for jobs (on my machine,
97 I can create and execute 48k simple coros/s with async,
98 and 128k coros with async_pool).
99 - Coro::AIO now uses the coroutine priority as io priority.
100
1013.2 Fri Dec 22 05:07:09 CET 2006
102 - improve portability to slightly older perls.
103 - use cleaner coroutine destruction.
104 - simplify configuration for users.
105 - optionally (unrecommended) prefer perl functions over
106 their coro replacements.
107
1083.11 Tue Dec 5 13:11:24 CET 2006
109 - fixed some bogus assert's, but as perl.h disables assert even
110 without NDEBUG (thank you very much), not too many people should
111 notice (that did include myself). Andreas König noticed, though :)
112 - do not save/restore PL_sortcxix on >= 5.9.x, it doesn't seem to have
113 it. Also noticed by Andreas König :)
114 - save/restore tainted status.
115 - verified to pass the testsuite on my 5.9.5.
116
1173.1 Mon Dec 4 23:03:40 CET 2006
118 - INCOMPATIBLE CHANGE: $/ is now per-coroutine (but slow).
119 - incompatible change: transfer flags are now per-state.
120 - give a better error message on deadlock.
121 - document Coro::nready.
122 - enhanced testsuite.
123
1243.01 Sun Dec 3 23:47:42 CET 2006
125 - forgot to include Coro::Timer.
126
1273.0 Sun Dec 3 22:57:25 CET 2006
128 - the "FINALLY COMPLETELY STABLE" release (coming soon:
129 the "FAMOUS LAST WORDS" release).
130 - implement a new stack sharing algorithm, which uses a stack
131 pool (size currently hardcoded).
132 - make stack sharing mandatory (it no longer uses a heuristic).
133 - eval/die no longer cause weird problems under heavy use.
134 - Coro::Event could cause livelocks if it was used but
135 no Coro::Event watchers were used.
136 - Coro::Event now uses asynccheck as prepare does not
137 check for changed watchers.
138 - Coro::Event allows multiple waiting coros and will wake up one
139 per event.
140 - Coro::Event should be cleaner and more efficient now.
141 - new utility function Coro::unblock_sub.
142 - document the sad fact that Event is no longer reentrant.
143 - putting a coroutine into the ready queue twice could under
144 some circumstances lead to stack corruption.
145 - minor incompatibility: subclassing Coro::State is supported
146 directly now without going through a _coro_state member.
147 - state/coro switching is much faster now.
148 - very minor optimisations and code/documentation cleanup.
149 - avoid problems due to compiler inlining.
150 - removed timers from Coro::Timer -> use AnyEvent instead.
151 - replaced Coro::idle coroutine by (cleaner) idle handler.
152 - updated to newest libcoro.
153 - implement enhanced support for valgrind.
154 - implement is_ready and return value for ready.
155 - removed Coro::Cont, it was a misnomer (it's generators),
156 and it was somewhat annoying to get it right. Will come back
157 if somebody asks for it :)
158 - many ->wait methods and Coro::Event could return
159 spuriously without the event having happened.
160
1612.5 Tue Nov 7 12:22:33 CET 2006
162 - made Coro::Util, Coro::Select, Coro::Handle and Coro::Socket
163 use AnyEvent, moved them to Coro/.
164 - added Coro::LWP which contains all the uglyness required to
165 make LWP non-blocking.
166 - should work with perl 5.9.x now (Andreas König made me do it).
167 - fixed another bug in Coro::Select when the timeout was undef.
168 - reuse PL_start_env for all coros, saves some memory per coroutine.
169 - manage PL_top_env differently, hopefully to avoid panic: top_env.
170 - timeout argument was not properly used in Coro::Socket.
171 - allow limited forms of subclassing in Coro::Handle/Coro::Socket.
172 - emulate undocumented(!) functionality of IO::Socket required
173 by LWP(!!).
174 - updated eg/lwp to work with newer lwp's.
175 - remove "FATAL: uncaught exception" prefix. Coroutines that die
176 kill the whole process, just as exceptions in the main "coroutine"
177 did already.
178
1792.1 Wed Nov 1 23:01:13 CET 2006
180 - fix a long-standing bug in Coro::Select where select with
181 zero timeout would instead change the current default filehandle.
182 - use a simpler and hopefully more robust way to clone padlists
183 (uses less memory and a perl function instead of our own).
184 - coro can now create a stack guard area on many architectures.
185 - Coro::AIO properly reexports additional functions from IO::AIO.
186 - updated libcoro with a workaround for OS X,
187 pach and testing by Michael Schwern.
188
1892.0 Tue Oct 24 05:47:17 CEST 2006
190 - support additional aio requests in Coro::AIO.
191
1921.9 (never properly released due to a glitch)
193
1941.8 Thu Feb 2 00:59:06 CET 2006
195 - applied suggested patch by SAMV to avoid problems during stupid
196 mark & sweep gc run.
197 - applied patch by Scott Walters for 5.9.3 compatibility.
198
1991.7 Tue Dec 27 01:41:58 CET 2005
200 - added Coro::AIO, a thin wrapper around IO::AIO.
201 - improved Makefile.PL explanations.
202
2031.6 Mon Dec 12 21:30:05 CET 2005
204 - additionally save PM_curpm might fix as-of-yet
205 unseen problems with regex matches being attributed to the
206 wrong package.
207 - add t/10_bugs.t, which currently checks against imho broken
208 perls that use 0.26MB of stack space per Perl_magic_get
209 invocation (newer linuxes) as opposed to the 0.0002MB perl
210 normally uses.
211 - make stacksize configurable for the ultimate debian experience.
212
2131.51 Mon Dec 12 18:48:36 CET 2005
214 - remove debugging warn() accidentally left in Coro::Select.
215
2161.5 Tue Nov 29 13:32:44 CET 2005
217 - use Coro::Event inside Coro::Select to avoid spurious deadlocks.
218 - fix Coro::Select 'select'.
219 - strict'ify some modules.
220 - libcoro errornously restored the SIGUSR2 handler to SIGUSR1.
221 - use XSLoader in selected modules.
222 - remove some 5.6 compatibility cruft.
223
2241.4 Tue Sep 6 00:11:05 CEST 2005
225 - libcoro did not take into account the trampoline on amd64,
226 when 'l'inux method was used.
227
2281.31 Tue Aug 30 23:31:33 CEST 2005
229 - some portability fixes/workarounds.
230
2311.3 Sat Aug 20 03:08:56 CEST 2005
232 - no code changes. module seems to work fine.
233 - improve Coro::State docs, remove reference to nonexisting
234 Coro::State::flush method.
235 - no longer autodetect windows, present it as an option instead.
236
2371.2 Mon May 16 02:00:55 CEST 2005
238 - included libcoro.c earlier in State.xs, might improve portability.
239 - use a faster and possibly more stable Coro::Cont implementation.
240 - accept x86_64 in addition to amd64 for optimized linux-amd64 support.
241 - fix bugs Coro::SemaphoreSet that could cause locks never to be freed.
242 - fix bugs in CoroAPI.h and document it in Coro::MakeMaker.
243
2441.11 Thu Mar 3 18:00:52 CET 2005
245 - change of contact address.
246
2471.1 Tue Feb 22 20:51:16 CET 2005
248 - support [l]inux method on amd64.
249 - allow some context switches while compiling/eval'ing.
250
2511.0 Tue Aug 10 03:47:27 CEST 2004
252 - Event 0.89 fixes the bug again.
253 - fix the remaining(??) memleak. I didn't free the cache-AV for
254 padlists, so one AV per created anon-sub leaked.
255
2560.97 Fri May 14 15:23:32 CEST 2004
257 - remove stupid gcc extension that was an experiment only anyway.
258
2590.96 Thu May 13 18:09:29 CEST 2004
260 - tell people if they have yet another broken Event variant.
261 - made Coro to work _better_ with threads (it seems that, as long
262 as you use Coros in one thread only everything will work fine.
263 Looking at the perl source the problem might be missing locking
264 between Coro and some perl internal routines. That's not easily
265 fixable).
266 - (hopefully) got rid of the static xnext inside transfer.
267
2680.95 Sun Feb 15 03:20:28 CET 2004
269 - removed Coro::State::flush, implemented a new and much
270 faster caching mechanism by attaching magic to the CV.
271 - a memleak with (real) closures remains.
272 - dramatically reduced size of stacks to 65536 (linux/x86), after
273 observing that even myhttpd never had more than a kilobyte
274 of stack in use (stack is still only physically allocated in
275 pagesize increments for systems suporting mmap).
276 - fix for a "cygwin-64" architecture added, proposed by Stefan Traby.
277 - fix for threaded perl.
278
2790.9 Sun Nov 23 04:32:39 CET 2003
280 - fix a few very hard to track down but (of course) stupid
281 memory leaks.
282 - stringify version number to avoid locale problems :(.
283 - perl 5.9.0 does not have SvPADBUSY, reported by Scott Walters,
284 hopefully ignoring it "just works".
285
2860.8 Wed Nov 5 19:38:40 CET 2003
287 - port to perl5.005_03, but only 5.8.x+ is supported!
288 - honor LocalAddr even without LocalPort in Coro::Socket.
289
2900.7 Tue May 27 03:12:38 CEST 2003
291 - the version jump indicates some level of testing, not gobs
292 of new features.
293 - uh... I found the prompt function in ExtUtils::MakeMaker.
294 Highly correct stuff, that is...
295 - fixed(?) a bug with die's in coroutines causing "panic: top_env".
296 the fix is not well understood by the author, so beware :(.
297
2980.652 Thu May 8 02:54:46 CEST 2003
299 - Applied patch by Slaven Rezic to set default to "s" on FreeBSD,
300 cause version 4 doesn't have ucontext.
301 - Benjamin Reed reported that setjmp works fine on darwin,
302 so preselect it.
303
3040.651 Sat Mar 29 15:00:23 CET 2003
305 - fix a bug in Coro::Handle where some bytes could get lost
306 on reading, reported by jason@nichego.net.
307
3080.65 Sun Mar 23 00:08:26 CET 2003
309 - added a README.linux-glibc.
310 - new module Coro::Select.
311 - also save/restore PL_comppad, fixes segfaults with 5.8.1.
312 (I never claimed that I know what I am doing ;).
313 - set default to setjmp/longjmp on non-x86-linux.
314
3150.6 Thu Nov 21 11:09:06 CET 2002
316 - made lazy context switching the default.
317 - fixed the bug where SemaphoreSet::guard
318 was the same as timed_guard and timed_guard was missing.
319 - fix a memleak in Coro::Timer.
320 - reclassified context sharing as not experimental.
321
3220.534 Sun Apr 14 03:05:12 CEST 2002
323 - fixed backspace => tab in header parsing (myhttpd).
324 - added eg/readline, for elmex.
325 - Coro::Event now calls ->start on first call instead of
326 ->again, which created wrong timeouts for the first ->next.
327 - fixed a bug where Coro::Socket returned a closed socket instead
328 of nothing on ECONNREFUSED and similar error conditions.
329
3300.533 Mon Feb 18 18:49:40 CET 2002
331 - adapt to finally working Event-0.85.
332 - fixed buggy event initialization (trapped under windows, but how
333 could it possibly have worked anywhere?)
334
3350.532 Wed Jan 16 02:45:32 CET 2002
336 - removed the reference to pp_entersub, might work on
337 (some) win32 perls now (testsuite works under cygwin,
338 without Event, which freezes).
339
3400.531 Mon Dec 10 22:18:44 CET 2001
341 - Fixed a bug in SemaphoreSet::timed_down.
342
3430.53 Tue Nov 27 21:11:13 CET 2001
344 - some tests for Event.
345 - slightly different internal architecture to get refcnt into the object
346 and not the reference. might fix a few bugs, certainly did introduce
347 new ones.
348 - Coro::Timer (independent of Event).
349 - new timed_wait functions for Coro::Signal, Semaphore, SemaphoreSet.
350
3510.52 Tue Nov 6 21:36:18 CET 2001
352 - ported to cygwin (trivial).
353 patch by Gerrit P. Haase <gp@familiehaase.de>.
354 - small setjmp code fix by Sullivan.DanielJ@epamail.epa.gov.
355
30.51 Thu Nov 1 20:39:01 CET 2001 3560.51 Thu Nov 1 20:39:01 CET 2001
4 - terminate/cancel now work properly (otherwise termination 357 - terminate/cancel now work properly (otherwise termination
5 could cause a "next coroutine is not and contains not..." 358 could cause a "next coroutine is not and contains not..."
6 error. 359 error.
7 - added Coro::Socket::shutdown. 360 - added Coro::Socket::shutdown.
8 - Coro::Event::loop no is the same as Event::loop. 361 - Coro::Event::loop no is the same as Event::loop.
9 - implemented terminate with args + join. 362 - implemented terminate with args + join.

110.5 Fri Sep 28 16:15:35 CEST 2001 3640.5 Fri Sep 28 16:15:35 CEST 2001
12 - fixed "print" on a Coro::Handle. The print method worked. 365 - fixed "print" on a Coro::Handle. The print method worked.
13 - small tweaks (seem to reduce memory consumption a lot) 366 - small tweaks (seem to reduce memory consumption a lot)
14 in various modules. 367 in various modules.
