# User Rev Content
1 root 1.1 Revision history for Perl extension Coro.
2 root 1.113
3 root 1.218 TODO: should explore PerlIO::via::CoroCede and PerlIO::via::CoroAIO.
4 root 1.226 TODO: maybe implement a default message channel, very much like Erlang
5     (which is cool in a lot of important aspects (failures!),
6 root 1.247 but very lacking in others (higher level ipc)).
7 root 1.173
8 root 1.289 4.2 Fri Nov 9 20:47:05 CET 2007
9 root 1.282 - enable/disable tracing from a new coroutine, not a pooled one.
10 root 1.283 - fix a memleak in Coro::Event.
11 root 1.284 - removed killall call from fork_eval.
12     - made sure store_fd is already loaded so that fork_eval
13     does not have to parse autoload in each subprocess.
14 root 1.288 - only use assembly method if -O switch is in $Config{optimize}.
15 root 1.289 - add (optional) Coro::EV module, so far the best event loop module
16     directly supported by Coro.
17     - if the event model is EV, use EV::DNS to resolve
18     stuff in Coro::Util.
19 root 1.286 - don't get confused by multiple event notifications in Coro::Handle.
20 root 1.287 - initial support for EV (libevent interface).
21 root 1.289 - require Event and EV using configure_requires, to force their existance.
22 root 1.282
23 root 1.281 4.13 Wed Oct 24 07:26:45 CEST 2007
24 root 1.277 - add Coro::Storable::blocking_thaw.
25 root 1.278 - use a vastly more complicated technique to localise
26     $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
27 root 1.279 - use a coroutine for the idle callback Coro::Event,
28     instead of running Event in the current coroutine context.
29     This also catches recursive invocations.
30 root 1.280 - actually report fork errors in gethostbyname and inet_aton.
31 root 1.277
32 root 1.276 4.11 Thu Oct 11 02:40:24 CEST 2007
33     - port to threaded perls.
34    
35 root 1.275 4.1 Thu Oct 11 02:38:16 CEST 2007
36 root 1.264 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
37     be local to each coro (see Coro::State).
38 root 1.274 - incompatible change: for very deep reasons, cede and cede_notself
39     cannot return anything, so nothing will be returned.
40 root 1.264 - possibly bring back 5.10 compatibility (untested).
41     - work around stupid (and wrong) warning on 5.10 :(.
42     - overlay the saved state over the context stack. This saves
43     a few hundred bytes per coroutine on average and also
44     speeds up context switching a bit.
45 root 1.265 - further tune default stack sizes.
46 root 1.264 - (more) correctly calculate stack usage in coro_rss.
47 root 1.267 - Coro::Storable::blocking_* did not properly lock
48     resulting in races between coroutines.
49     - added Coro::Storable::guard.
50 root 1.268 - stopping to trace a coroutine could destroy the cctx of
51     an unrelated coroutine.
52 root 1.269 - explain the relationship between Perl and C coroutines in
53     more detail in Coro::State.
54 root 1.270 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
55     causing a fork per resolve. This also affected Coro::Socket.
56 root 1.272 - switch to a separate stack in $coro->call/eval to avoid
57     invalidating pointers.
58 root 1.264
59 root 1.263 4.03 Sat Oct 6 21:24:00 CEST 2007
60 root 1.262 - added Coro::throw method.
61     - minor code cleanups.
62    
63 root 1.261 4.02 Sat Oct 6 02:36:47 CEST 2007
64 root 1.258 - fix a very minor per-coroutine memleak (a single codereference).
65 root 1.259 - fixed a bug where the currently in-use c context would be freed
66     prematurely (can happen only when programs change the stacksize
67     or use tracing).
68     - tracing can no longer keep a coro alive after it terminated.
69 root 1.260 - do static branch prediction in the common path for gcc. gives
70     about 2-5% speed improvement here.
71 root 1.258
72 root 1.256 4.01 Fri Oct 5 22:10:49 CEST 2007
73 root 1.257 - instead of recreating *a* standard output handle we simply
74     use STDOUT, which is faster and hopefully more robust.
75 root 1.255
76 root 1.254 4.0 Fri Oct 5 12:56:00 CEST 2007
77 root 1.238 - incompatibly changed Coro::Storable::freeze.
78 root 1.244 - major new feature: added Coro::Debug, for interactive coroutine
79     debugging, tracing and much more.
80 root 1.252 - major bug fix: unbelievable, but true: $_, $/ and many other
81     "saved" variables actually weren't being saved. This has been fixed,
82     of course, while increasing performance while losing all the save
83     flags.
84 root 1.251 - save flags are gone, and all the api functions dealing with them.
85 root 1.232 - added Coro::Semaphore::adjust.
86 root 1.233 - added Coro::Util::fork_eval.
87     - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
88 root 1.248 - added Coro::killall.
89 root 1.236 - reduce initial stack sizes to allow for "micro-coroutines".
90 root 1.239 - better async_pool resource management, moved parts of async_pool
91 root 1.240 handling to XS (major speed improvement).
92 root 1.245 - actually croak before modifying important data structures.
93     - refuse to transfer while compiling.
94     - possibly support eval EXPR better now.
95 root 1.249 - enable assembly per default on linux+bsd x86+amd64.
96 root 1.253 - all internal members were renamed _something for easier subclassing.
97 root 1.237 - many minor tweaks.
98 root 1.232
99 root 1.231 3.63 Wed May 16 14:10:06 CEST 2007
100 root 1.230 - implement handcoded assembly for x86/amd64 SVR ABI.
101    
102 root 1.229 3.62 Fri Apr 27 21:36:06 CEST 2007
103     - upgrade libcoro (which might set unwind info correctly).
104 root 1.228 - change default on linux to setjmp/longjmp.
105 root 1.227
106 root 1.226 3.61 Thu Apr 19 12:36:18 CEST 2007
107 root 1.225 - Coro::Storable caused an endless loop when thawing invalid
108     pst's sometimes.
109 root 1.223 - use a Semaphore in Coro::Storable, as Storable doesn't
110 root 1.224 seem to be reentrant (although it is documented to
111     be threadsafe...).
112     - fix Coro::Signal to bring back the original unreliable
113     but stateful semantics.
114 root 1.226 - fixed a lot of typos in Coro.pm (patch submitted by David
115     Steinbrunner, which applied flawlessly).
116 root 1.223
117     3.6 Sat Apr 14 17:13:31 CEST 2007
118 root 1.217 - added some bugfixes to get eg/myhttpd working again.
119 root 1.218 - added Coro::Storable for often-cede'ing freeze/thaw.
120 root 1.219 - try to do a clean exit when a coroutine calls exit
121     (EXPERIMENTAL).
122 root 1.220 - got rid of indirect call through _coro_init.
123     - updated the partly antique examples in eg/ to
124     work again and be a bit less magic, too.
125     - fixed Coro::Signal semantics to work as documented again.
126 root 1.217
127 root 1.216 3.55 Sun Mar 25 01:20:47 CET 2007
128 root 1.215 - add SAVE_DEFFH to save the default filehandle and enable
129     it by default.
130     - finally move socket-operations from Coro::Socket to Coro::Handle
131     to be able to unblock foreign sockets.
132     - add Coro::State::save_also and guarded_save.
133 root 1.211 - add count accessor to Coro::Semaphore.
134 root 1.212 - add Coro::State::cctx_stacksize.
135 root 1.213 - just for the fun of it, do not rely on implicit context,
136     which can dramatically improve performance, but people
137     using windows-process-emulation perls do not care much about
138     performance.
139 root 1.211
140 root 1.210 3.51 Sun Mar 4 14:18:04 CET 2007
141 root 1.209 - fixed a problem when you weakened references to Coro::State's
142     (patch by Yuval Kogman).
143    
144 root 1.208 3.501 Wed Feb 28 12:44:07 CET 2007
145     - rename some global symbols as macosx from hell redefines
146     them without asking.
147    
148 root 1.207 3.5 Tue Feb 13 20:22:53 CET 2007
149 root 1.204 - do AnyEvent model detection earlier, avoiding problems
150     caused by first using AnyEvent and later Coro::Event.
151 root 1.205 - implement and document Coro::Event event objects.
152     - fix a potential problem in Coro::Event causing crashes.
153 root 1.206 - initialise PL_comppad when creating a new coroutine,
154     avoids crashes on early coro destruction.
155 root 1.204
156 root 1.203 3.41 Mon Jan 22 19:19:49 CET 2007
157 root 1.202 - readline on Coro::Handle did not support undefined $/,
158     nor did it deliver partial lines on EOF or error.
159 root 1.203 - implement malloc fallback for stack allocation because
160     stupid broken idiotic OSX has a stupid broken
161     idiotic fits-the-whole-os mmap "implementation" and
162     my dick feels longer if Coro is portable even to
163     obsolete platforms.
164 root 1.202
165 root 1.201 3.4 Fri Jan 19 21:52:54 CET 2007
166 root 1.197 - remove t/09_timer.t, as it isn't really testing much
167     but was rather flaky in practise.
168 root 1.198 - async_pool coro would keep arguments and callback alive until
169     it was reused.
170 root 1.199 - cancellation of a coroutine could cause spurious idle calls
171     in cede_notself.
172 root 1.197
173 root 1.196 3.3 Sat Jan 6 03:45:00 CET 2007
174 root 1.187 - implement $coro->on_destroy.
175 root 1.188 - Coro::Event blocking semantics have been changed,
176     documented and - hopefully - improved.
177 root 1.184 - fix nice adding, not subtracting, from priority.
178 root 1.185 - fix ->prio and api_is_ready (patch by Mark Hinds).
179 root 1.190 - fixed an assert ("... == prev__cctx->idle_te")
180     that could errronously trigger.
181 root 1.192 - fix various large and small memleaks.
182 root 1.191 - use a (hopefully) more stable cancel implementation
183     that immediately frees the coroutine data.
184 root 1.194 - cede/cede_notself return a status now.
185 root 1.191 - added Coro::guard function.
186 root 1.193 - added a global coroutine pool for jobs (on my machine,
187     I can create and execute 48k simple coros/s with async,
188     and 128k coros with async_pool).
189 root 1.195 - Coro::AIO now uses the coroutine priority as io priority.
190 root 1.184
191 root 1.183 3.2 Fri Dec 22 05:07:09 CET 2006
192 root 1.179 - improve portability to slightly older perls.
193 root 1.180 - use cleaner coroutine destruction.
194 root 1.182 - simplify configuration for users.
195     - optionally (unrecommended) prefer perl functions over
196     their coro replacements.
197 root 1.179
198 root 1.178 3.11 Tue Dec 5 13:11:24 CET 2006
199     - fixed some bogus assert's, but as perl.h disables assert even
200     without NDEBUG (thank you very much), not too many people should
201     notice (that did include myself). Andreas König noticed, though :)
202     - do not save/restore PL_sortcxix on >= 5.9.x, it doesn't seem to have
203     it. Also noticed by Andreas König :)
204     - save/restore tainted status.
205     - verified to pass the testsuite on my 5.9.5.
206    
207 root 1.177 3.1 Mon Dec 4 23:03:40 CET 2006
208     - INCOMPATIBLE CHANGE: $/ is now per-coroutine (but slow).
209 root 1.175 - incompatible change: transfer flags are now per-state.
210 root 1.173 - give a better error message on deadlock.
211 root 1.175 - document Coro::nready.
212 root 1.174 - enhanced testsuite.
213 root 1.169
214 root 1.172 3.01 Sun Dec 3 23:47:42 CET 2006
215     - forgot to include Coro::Timer.
216    
217 root 1.171 3.0 Sun Dec 3 22:57:25 CET 2006
218 root 1.163 - the "FINALLY COMPLETELY STABLE" release (coming soon:
219     the "FAMOUS LAST WORDS" release).
220 root 1.166 - implement a new stack sharing algorithm, which uses a stack
221     pool (size currently hardcoded).
222 root 1.155 - make stack sharing mandatory (it no longer uses a heuristic).
223 root 1.157 - eval/die no longer cause weird problems under heavy use.
224 root 1.152 - Coro::Event could cause livelocks if it was used but
225 root 1.161 no Coro::Event watchers were used.
226 root 1.167 - Coro::Event now uses asynccheck as prepare does not
227     check for changed watchers.
228 root 1.170 - Coro::Event allows multiple waiting coros and will wake up one
229     per event.
230 root 1.152 - Coro::Event should be cleaner and more efficient now.
231 root 1.165 - new utility function Coro::unblock_sub.
232 root 1.164 - document the sad fact that Event is no longer reentrant.
233 root 1.163 - putting a coroutine into the ready queue twice could under
234     some circumstances lead to stack corruption.
235 root 1.161 - minor incompatibility: subclassing Coro::State is supported
236     directly now without going through a _coro_state member.
237 root 1.156 - state/coro switching is much faster now.
238 root 1.154 - very minor optimisations and code/documentation cleanup.
239 root 1.153 - avoid problems due to compiler inlining.
240 root 1.154 - removed timers from Coro::Timer -> use AnyEvent instead.
241     - replaced Coro::idle coroutine by (cleaner) idle handler.
242 root 1.156 - updated to newest libcoro.
243 root 1.159 - implement enhanced support for valgrind.
244 root 1.162 - implement is_ready and return value for ready.
245 root 1.168 - removed Coro::Cont, it was a misnomer (it's generators),
246     and it was somewhat annoying to get it right. Will come back
247     if somebody asks for it :)
248 root 1.163 - many ->wait methods and Coro::Event could return
249     spuriously without the event having happened.
250 root 1.146
251 root 1.145 2.5 Tue Nov 7 12:22:33 CET 2006
252 root 1.143 - made Coro::Util, Coro::Select, Coro::Handle and Coro::Socket
253     use AnyEvent, moved them to Coro/.
254 root 1.140 - added Coro::LWP which contains all the uglyness required to
255     make LWP non-blocking.
256     - should work with perl 5.9.x now (Andreas König made me do it).
257 root 1.141 - fixed another bug in Coro::Select when the timeout was undef.
258 root 1.136 - reuse PL_start_env for all coros, saves some memory per coroutine.
259     - manage PL_top_env differently, hopefully to avoid panic: top_env.
260 root 1.137 - timeout argument was not properly used in Coro::Socket.
261     - allow limited forms of subclassing in Coro::Handle/Coro::Socket.
262 root 1.138 - emulate undocumented(!) functionality of IO::Socket required
263     by LWP(!!).
264     - updated eg/lwp to work with newer lwp's.
265 root 1.140 - remove "FATAL: uncaught exception" prefix. Coroutines that die
266     kill the whole process, just as exceptions in the main "coroutine"
267     did already.
268 root 1.135
269 root 1.134 2.1 Wed Nov 1 23:01:13 CET 2006
270     - fix a long-standing bug in Coro::Select where select with
271     zero timeout would instead change the current default filehandle.
272 root 1.132 - use a simpler and hopefully more robust way to clone padlists
273     (uses less memory and a perl function instead of our own).
274     - coro can now create a stack guard area on many architectures.
275 root 1.134 - Coro::AIO properly reexports additional functions from IO::AIO.
276 root 1.132 - updated libcoro with a workaround for OS X,
277 root 1.134 pach and testing by Michael Schwern.
278 root 1.130
279 root 1.129 2.0 Tue Oct 24 05:47:17 CEST 2006
280 root 1.128 - support additional aio requests in Coro::AIO.
281    
282 root 1.129 1.9 (never properly released due to a glitch)
283    
284 root 1.127 1.8 Thu Feb 2 00:59:06 CET 2006
285 root 1.125 - applied suggested patch by SAMV to avoid problems during stupid
286     mark & sweep gc run.
287 root 1.126 - applied patch by Scott Walters for 5.9.3 compatibility.
288 root 1.125
289 root 1.124 1.7 Tue Dec 27 01:41:58 CET 2005
290 root 1.123 - added Coro::AIO, a thin wrapper around IO::AIO.
291 root 1.122 - improved Makefile.PL explanations.
292    
293 root 1.119 1.6 Mon Dec 12 21:30:05 CET 2005
294 root 1.117 - additionally save PM_curpm might fix as-of-yet
295 root 1.121 unseen problems with regex matches being attributed to the
296 root 1.117 wrong package.
297 root 1.118 - add t/10_bugs.t, which currently checks against imho broken
298     perls that use 0.26MB of stack space per Perl_magic_get
299 root 1.121 invocation (newer linuxes) as opposed to the 0.0002MB perl
300     normally uses.
301 root 1.120 - make stacksize configurable for the ultimate debian experience.
302 root 1.117
303 root 1.116 1.51 Mon Dec 12 18:48:36 CET 2005
304     - remove debugging warn() accidentally left in Coro::Select.
305    
306 root 1.115 1.5 Tue Nov 29 13:32:44 CET 2005
307 root 1.114 - use Coro::Event inside Coro::Select to avoid spurious deadlocks.
308 root 1.115 - fix Coro::Select 'select'.
309     - strict'ify some modules.
310 root 1.112 - libcoro errornously restored the SIGUSR2 handler to SIGUSR1.
311 root 1.115 - use XSLoader in selected modules.
312     - remove some 5.6 compatibility cruft.
313 root 1.112
314 root 1.111 1.4 Tue Sep 6 00:11:05 CEST 2005
315     - libcoro did not take into account the trampoline on amd64,
316     when 'l'inux method was used.
317    
318 root 1.110 1.31 Tue Aug 30 23:31:33 CEST 2005
319     - some portability fixes/workarounds.
320    
321 root 1.107 1.3 Sat Aug 20 03:08:56 CEST 2005
322 root 1.108 - no code changes. module seems to work fine.
323 root 1.106 - improve Coro::State docs, remove reference to nonexisting
324     Coro::State::flush method.
325 root 1.107 - no longer autodetect windows, present it as an option instead.
326 root 1.106
327 root 1.105 1.2 Mon May 16 02:00:55 CEST 2005
328 root 1.100 - included libcoro.c earlier in State.xs, might improve portability.
329 root 1.101 - use a faster and possibly more stable Coro::Cont implementation.
330 root 1.102 - accept x86_64 in addition to amd64 for optimized linux-amd64 support.
331 root 1.104 - fix bugs Coro::SemaphoreSet that could cause locks never to be freed.
332 root 1.105 - fix bugs in CoroAPI.h and document it in Coro::MakeMaker.
333 root 1.100
334 root 1.99 1.11 Thu Mar 3 18:00:52 CET 2005
335     - change of contact address.
336    
337 root 1.98 1.1 Tue Feb 22 20:51:16 CET 2005
338 root 1.97 - support [l]inux method on amd64.
339 root 1.109 - allow some context switches while compiling/eval'ing.
340 root 1.97
341 root 1.96 1.0 Tue Aug 10 03:47:27 CEST 2004
342 root 1.95 - Event 0.89 fixes the bug again.
343 root 1.96 - fix the remaining(??) memleak. I didn't free the cache-AV for
344     padlists, so one AV per created anon-sub leaked.
345 root 1.95
346 pcg 1.94 0.97 Fri May 14 15:23:32 CEST 2004
347     - remove stupid gcc extension that was an experiment only anyway.
348    
349 pcg 1.93 0.96 Thu May 13 18:09:29 CEST 2004
350 root 1.103 - tell people if they have yet another broken Event variant.
351 pcg 1.91 - made Coro to work _better_ with threads (it seems that, as long
352     as you use Coros in one thread only everything will work fine.
353     Looking at the perl source the problem might be missing locking
354     between Coro and some perl internal routines. That's not easily
355     fixable).
356 pcg 1.92 - (hopefully) got rid of the static xnext inside transfer.
357 pcg 1.91
358 pcg 1.90 0.95 Sun Feb 15 03:20:28 CET 2004
359 pcg 1.86 - removed Coro::State::flush, implemented a new and much
360     faster caching mechanism by attaching magic to the CV.
361 pcg 1.87 - a memleak with (real) closures remains.
362 pcg 1.88 - dramatically reduced size of stacks to 65536 (linux/x86), after
363     observing that even myhttpd never had more than a kilobyte
364     of stack in use (stack is still only physically allocated in
365     pagesize increments for systems suporting mmap).
366 pcg 1.89 - fix for a "cygwin-64" architecture added, proposed by Stefan Traby.
367 pcg 1.90 - fix for threaded perl.

370 pcg 1.84 - fix a few very hard to track down but (of course) stupid
371     memory leaks.
372     - stringify version number to avoid locale problems :(.
373 pcg 1.85 - perl 5.9.0 does not have SvPADBUSY, reported by Scott Walters,
374     hopefully ignoring it "just works".
375 pcg 1.84
376 pcg 1.83 0.8 Wed Nov 5 19:38:40 CET 2003
377     - port to perl5.005_03, but only 5.8.x+ is supported!
378 pcg 1.82 - honor LocalAddr even without LocalPort in Coro::Socket.
379    
380 root 1.81 0.7 Tue May 27 03:12:38 CEST 2003
381     - the version jump indicates some level of testing, not gobs
382     of new features.
383 root 1.80 - uh... I found the prompt function in ExtUtils::MakeMaker.
384     Highly correct stuff, that is...
385 root 1.81 - fixed(?) a bug with die's in coroutines causing "panic: top_env".
386     the fix is not well understood by the author, so beware :(.

404 root 1.72
405 root 1.71 0.6 Thu Nov 21 11:09:06 CET 2002

418     of nothing on ECONNREFUSED and similar error conditions.
419 root 1.69
420 root 1.68 0.533 Mon Feb 18 18:49:40 CET 2002
421     - adapt to finally working Event-0.85.
422     - fixed buggy event initialization (trapped under windows, but how
423     could it possibly have worked anywhere?)
424    
425 root 1.67 0.532 Wed Jan 16 02:45:32 CET 2002
426 root 1.66 - removed the reference to pp_entersub, might work on
427     (some) win32 perls now (testsuite works under cygwin,
428     without Event, which freezes).
429 root 1.65

447 root 1.54 - terminate/cancel now work properly (otherwise termination
448     could cause a "next coroutine is not and contains not..."
449     error.
450 root 1.55 - added Coro::Socket::shutdown.
451 root 1.56 - Coro::Event::loop no is the same as Event::loop.

454 root 1.64 0.5 Fri Sep 28 16:15:35 CEST 2001

463     inside Coro::Handle.
464 root 1.44 - make Coro::Handle use an array instead of a hash for
465     speed reasons.

467     sjlj and ucontext should now work.
468     - IRIX-specific port for libcoro.
469 root 1.45 - swapped order of accept results to match IO::Socket.
470 root 1.46 - changed getsock/peername to sock/peername to match IO::Socket.

500 root 1.29 - do not use mmap if neither MAP_ANON nor MAP_ANONYMOUS is defined.
501 root 1.34 - very experimental stack sharing algorithm. not 100% safe but
502 root 1.28 should work well in practise ;)

512 root 1.23 - release candidate 3. A rather new internal structure :(
513 root 1.24 - the great renaming: Damian Conway gave me a suitable replacement
514     for yield.
515 root 1.23 - added Coro/libcoro, a portable coroutine implementation for C
516 root 1.22 (not even perl-dependent!!!), which can be used by Coro::State.
517 root 1.20 - renamed SAVE_DEFSV (on xs-level only) to avoid symbol clash in
518     perl-5.6.
519 root 1.16 - new function Coro::Event::idle.
520     - the idle process is now overriden
521     by default in Coro::Event.

542    
543 root 1.11 0.06 Tue Jul 17 04:23:24 CEST 2001
544     - ok, I found the showstopper - the same sub must not be
545 root 1.9 re-entered in two different coroutines, otherwise => crash. I
546     see no easy solution to this problem, except by walking the call
547     chaing and saving/restoring the cv's, which is what I do now.
548 root 1.11 - memory leaks still latent, especially at thread termination.

562 root 1.4
563 root 1.3 0.03 Fri Jul 13 14:51:52 CEST 2001
564 root 1.4 - transfer() now implemented in XS (beware).
565     - new module Coro::Cont for really faked continuations.
566     - big internal architecture changes: Coro::State is now
567 root 1.3 really low-level and can thus be used to implement other
568 root 1.4 interesting things, While "Coro::" implements a process-like
569     model. Still crude and subject to change.
