# 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 1.328 TODO: maybe implement a default message channel, very much like Erlang's
5     actor model (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 1.341 TODO: Coro::AnyEvent
9     - implement cancel, ready and kill commands in Coro::Debug.
10     - document find_coro in Coro::Debug.
11    
12 root 1.340 4.6 Sat Apr 26 10:05:14 CEST 2008
13 root 1.336 - INCOMPATIBLE CHANGE: sub/code attributes are no longer supported
14 root 1.339 by the Coro module. It was a mistake to have it in the first place.
15     - (experimental) support for activestate perl 5.10 (method "w").
16     - (experimental) support for strawberry perl (method "a").
17 root 1.337 - coro_sigelem_set did not return a value although it had to,
18     actual impact unknown.
19 root 1.336
20 root 1.335 4.51 Mon Apr 14 13:28:27 CEST 2008
21     - make it compile again on 5.8.
22    
23 root 1.334 4.50 Thu Apr 10 09:43:17 CEST 2008
24     - I did it twice! (see 4.49).
25    
26 root 1.333 4.49 Sun Apr 6 21:23:31 CEST 2008
27     - grr, instead of compiling the recent changes on 5.10 only they
28     were compiled on 5.8 only.
29    
30 root 1.332 4.48 Sun Apr 6 20:36:46 CEST 2008
31 root 1.331 - allow coroutine switches during eval's under 5.10.x, as it seems
32     the parser is a per-interpreter option now, so this is safe
33     (this might fix the odd crashing bug).
34 root 1.332 - drop support for 5.9.x versions: they are dead, jim.
35 root 1.331
36 root 1.330 4.47 Sun Apr 6 00:37:52 CEST 2008
37 root 1.329 - force cctx allocation on API calls: we know we need to force one
38     and gcc actually manages to confuse our heuristic nowadays,
39     leading to crashes and worse.
40 root 1.330 - document force_cctx.
41 root 1.329
42 root 1.328 4.46 Fri Apr 4 22:05:43 CEST 2008
43     - upgrade libcoro, resulting in pthread-backend (which was only created
44     to fulfill the rules of the programming languages shootout).
45    
46 root 1.327 4.45 Thu Mar 13 11:55:36 CET 2008
47 root 1.322 - fix a file leaking bug in eg/mhyttpd that would allow
48     downloading of any file (reported by oesi).
49 root 1.325 - fix deadlock bug in Coro::Channel (reported by Richard Hundt)
50     (also add testcase).
51 root 1.323 - support Broadcast option in Coro::Socket (patch by Richard Hundt,
52     apparently having loads of fun with that).
53 root 1.324 - implement $state->swap_defsv, ->swap_defav and document ->throw.
54 root 1.322
55 root 1.321 4.4 Wed Feb 13 16:44:29 CET 2008
56 root 1.319 - only assume .cfi pseudo isns exist on GNU/Linux.
57 root 1.320 - add get_timed method to Coro::Channels.
58 root 1.321 - fixed Coro::Debug manpage.
59     - perl 5.11 compatbility improvement based on patch by
60     Andreas König.
61 root 1.319
62 root 1.318 4.37 Sun Jan 20 11:25:23 CET 2008
63 root 1.317 - soften the check for an active parser for perl 5.10 (avoiding
64     "Coro::State::transfer called while parsing" in many cases).
65 root 1.316
66 root 1.315 4.36 Sun Jan 13 10:53:56 CET 2008
67 root 1.314 - reset diehook when terminating from an async_pool as to not
68     trigger any __DIE__ handlers.
69    
70 root 1.313 4.35 Sun Jan 13 04:14:13 CET 2008
71 root 1.308 - "bt" debug command now displays any exceptions
72 root 1.311 from longmess and also skips the innermost
73     stackframes, giving more useufl output.
74 root 1.309 - allow backtraces in coroutines blocked in Coro::EV,
75 root 1.310 at a <1% speed hit.
76 root 1.312 - handle localising of $SIG{__WARN__} and __DIE__
77 root 1.314 properly (with a proper amount of dirty hacking).
78 root 1.308
79 root 1.307 4.34 Sat Dec 22 17:49:53 CET 2007
80 root 1.306 - upgrade to EV version 2.0 API.
81    
82 root 1.305 4.33 Mon Dec 17 08:36:12 CET 2007
83     - make Coro::AIO etc. loadable in the absence of EV.
84    
85 root 1.304 4.32 Mon Dec 17 07:46:02 CET 2007
86 root 1.301 - majorly improved Coro::Handle's performance with Coro::EV.
87 root 1.302 - implemented the until now mythical Coro::BDB module.
88 root 1.304 - specialcase EV in Coro::AIO and Coro::BDB for extra speed.
89 root 1.301
90 root 1.300 4.31 Wed Dec 5 12:32:39 CET 2007
91     - remove warn statement form Coro::Util.
92    
93 root 1.299 4.3 Tue Dec 4 20:33:14 CET 2007
94     - calls to the idle function could cause stack corruption
95     when the stack changed.
96 root 1.295 - do no longer rely on the presence of EV::DNS if EV is used
97     (because it is gone), but instead take avdantage of EV::ADNS
98     if available.
99 root 1.296 - add ($) prototypes to all functions in Coro::Storable.
100 root 1.297 - use a conventional (safer) idle callback in Coro::EV.
101 root 1.298 - do accept quickly in Coro::Debug to avoid endless loops.
102 root 1.295
103 root 1.294 4.22 Fri Nov 30 16:04:04 CET 2007
104 root 1.293 - really use optimised versions for Event and EV in Coro::Util
105     and Coro::Handle.
106    
107 root 1.292 4.21 Sun Nov 25 10:48:59 CET 2007
108 root 1.290 - fix a spurious memory read.
109 root 1.291 - Coro::EV no longer keeps the eventloop "alive".
110 root 1.290
111 root 1.289 4.2 Fri Nov 9 20:47:05 CET 2007
112 root 1.282 - enable/disable tracing from a new coroutine, not a pooled one.
113 root 1.283 - fix a memleak in Coro::Event.
114 root 1.284 - removed killall call from fork_eval.
115     - made sure store_fd is already loaded so that fork_eval
116     does not have to parse autoload in each subprocess.
117 root 1.288 - only use assembly method if -O switch is in $Config{optimize}.
118 root 1.289 - add (optional) Coro::EV module, so far the best event loop module
119     directly supported by Coro.
120     - if the event model is EV, use EV::DNS to resolve
121     stuff in Coro::Util.
122 root 1.286 - don't get confused by multiple event notifications in Coro::Handle.
123 root 1.287 - initial support for EV (libevent interface).
124 root 1.289 - require Event and EV using configure_requires, to force their existance.
125 root 1.282
126 root 1.281 4.13 Wed Oct 24 07:26:45 CEST 2007
127 root 1.277 - add Coro::Storable::blocking_thaw.
128 root 1.278 - use a vastly more complicated technique to localise
129     $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
130 root 1.279 - use a coroutine for the idle callback Coro::Event,
131     instead of running Event in the current coroutine context.
132     This also catches recursive invocations.
133 root 1.280 - actually report fork errors in gethostbyname and inet_aton.
134 root 1.277
135 root 1.276 4.11 Thu Oct 11 02:40:24 CEST 2007
136     - port to threaded perls.
137    
138 root 1.275 4.1 Thu Oct 11 02:38:16 CEST 2007
139 root 1.264 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
140     be local to each coro (see Coro::State).
141 root 1.274 - incompatible change: for very deep reasons, cede and cede_notself
142     cannot return anything, so nothing will be returned.
143 root 1.264 - possibly bring back 5.10 compatibility (untested).
144     - work around stupid (and wrong) warning on 5.10 :(.
145     - overlay the saved state over the context stack. This saves
146     a few hundred bytes per coroutine on average and also
147     speeds up context switching a bit.
148 root 1.265 - further tune default stack sizes.
149 root 1.264 - (more) correctly calculate stack usage in coro_rss.
150 root 1.267 - Coro::Storable::blocking_* did not properly lock
151     resulting in races between coroutines.
152     - added Coro::Storable::guard.
153 root 1.268 - stopping to trace a coroutine could destroy the cctx of
154     an unrelated coroutine.
155 root 1.269 - explain the relationship between Perl and C coroutines in
156     more detail in Coro::State.
157 root 1.270 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
158     causing a fork per resolve. This also affected Coro::Socket.
159 root 1.272 - switch to a separate stack in $coro->call/eval to avoid
160     invalidating pointers.
161 root 1.264
162 root 1.263 4.03 Sat Oct 6 21:24:00 CEST 2007
163 root 1.262 - added Coro::throw method.
164     - minor code cleanups.
165    
166 root 1.261 4.02 Sat Oct 6 02:36:47 CEST 2007
167 root 1.258 - fix a very minor per-coroutine memleak (a single codereference).
168 root 1.259 - fixed a bug where the currently in-use c context would be freed
169     prematurely (can happen only when programs change the stacksize
170     or use tracing).
171     - tracing can no longer keep a coro alive after it terminated.
172 root 1.260 - do static branch prediction in the common path for gcc. gives
173     about 2-5% speed improvement here.
174 root 1.258
175 root 1.256 4.01 Fri Oct 5 22:10:49 CEST 2007
176 root 1.257 - instead of recreating *a* standard output handle we simply
177     use STDOUT, which is faster and hopefully more robust.
178 root 1.255
179 root 1.254 4.0 Fri Oct 5 12:56:00 CEST 2007
180 root 1.238 - incompatibly changed Coro::Storable::freeze.
181 root 1.244 - major new feature: added Coro::Debug, for interactive coroutine
182     debugging, tracing and much more.
183 root 1.252 - major bug fix: unbelievable, but true: $_, $/ and many other
184     "saved" variables actually weren't being saved. This has been fixed,
185     of course, while increasing performance while losing all the save
186     flags.
187 root 1.251 - save flags are gone, and all the api functions dealing with them.
188 root 1.232 - added Coro::Semaphore::adjust.
189 root 1.233 - added Coro::Util::fork_eval.
190     - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
191 root 1.248 - added Coro::killall.
192 root 1.236 - reduce initial stack sizes to allow for "micro-coroutines".
193 root 1.239 - better async_pool resource management, moved parts of async_pool
194 root 1.240 handling to XS (major speed improvement).
195 root 1.245 - actually croak before modifying important data structures.
196     - refuse to transfer while compiling.
197     - possibly support eval EXPR better now.
198 root 1.249 - enable assembly per default on linux+bsd x86+amd64.
199 root 1.253 - all internal members were renamed _something for easier subclassing.
200 root 1.237 - many minor tweaks.
201 root 1.232
202 root 1.231 3.63 Wed May 16 14:10:06 CEST 2007
203 root 1.230 - implement handcoded assembly for x86/amd64 SVR ABI.
204    
205 root 1.229 3.62 Fri Apr 27 21:36:06 CEST 2007
206     - upgrade libcoro (which might set unwind info correctly).
207 root 1.228 - change default on linux to setjmp/longjmp.
208 root 1.227
209 root 1.226 3.61 Thu Apr 19 12:36:18 CEST 2007
210 root 1.225 - Coro::Storable caused an endless loop when thawing invalid
211     pst's sometimes.
212 root 1.223 - use a Semaphore in Coro::Storable, as Storable doesn't
213 root 1.224 seem to be reentrant (although it is documented to
214     be threadsafe...).
215     - fix Coro::Signal to bring back the original unreliable
216     but stateful semantics.
217 root 1.226 - fixed a lot of typos in Coro.pm (patch submitted by David
218     Steinbrunner, which applied flawlessly).
219 root 1.223
220     3.6 Sat Apr 14 17:13:31 CEST 2007
221 root 1.217 - added some bugfixes to get eg/myhttpd working again.
222 root 1.218 - added Coro::Storable for often-cede'ing freeze/thaw.
223 root 1.219 - try to do a clean exit when a coroutine calls exit
224     (EXPERIMENTAL).
225 root 1.220 - got rid of indirect call through _coro_init.
226     - updated the partly antique examples in eg/ to
227     work again and be a bit less magic, too.
228     - fixed Coro::Signal semantics to work as documented again.
229 root 1.217
230 root 1.216 3.55 Sun Mar 25 01:20:47 CET 2007
231 root 1.215 - add SAVE_DEFFH to save the default filehandle and enable
232     it by default.
233     - finally move socket-operations from Coro::Socket to Coro::Handle
234     to be able to unblock foreign sockets.
235     - add Coro::State::save_also and guarded_save.
236 root 1.211 - add count accessor to Coro::Semaphore.
237 root 1.212 - add Coro::State::cctx_stacksize.
238 root 1.213 - just for the fun of it, do not rely on implicit context,
239     which can dramatically improve performance, but people
240     using windows-process-emulation perls do not care much about
241     performance.
242 root 1.211
243 root 1.210 3.51 Sun Mar 4 14:18:04 CET 2007
244 root 1.209 - fixed a problem when you weakened references to Coro::State's
245     (patch by Yuval Kogman).
246    
247 root 1.208 3.501 Wed Feb 28 12:44:07 CET 2007
248     - rename some global symbols as macosx from hell redefines
249     them without asking.
250    
251 root 1.207 3.5 Tue Feb 13 20:22:53 CET 2007
252 root 1.204 - do AnyEvent model detection earlier, avoiding problems
253     caused by first using AnyEvent and later Coro::Event.
254 root 1.205 - implement and document Coro::Event event objects.
255     - fix a potential problem in Coro::Event causing crashes.
256 root 1.206 - initialise PL_comppad when creating a new coroutine,
257     avoids crashes on early coro destruction.
258 root 1.204
259 root 1.203 3.41 Mon Jan 22 19:19:49 CET 2007
260 root 1.202 - readline on Coro::Handle did not support undefined $/,
261     nor did it deliver partial lines on EOF or error.
262 root 1.203 - implement malloc fallback for stack allocation because
263     stupid broken idiotic OSX has a stupid broken
264     idiotic fits-the-whole-os mmap "implementation" and
265     my dick feels longer if Coro is portable even to
266     obsolete platforms.
267 root 1.202
268 root 1.201 3.4 Fri Jan 19 21:52:54 CET 2007
269 root 1.197 - remove t/09_timer.t, as it isn't really testing much
270     but was rather flaky in practise.
271 root 1.198 - async_pool coro would keep arguments and callback alive until
272     it was reused.
273 root 1.199 - cancellation of a coroutine could cause spurious idle calls
274     in cede_notself.
275 root 1.197
276 root 1.196 3.3 Sat Jan 6 03:45:00 CET 2007
277 root 1.187 - implement $coro->on_destroy.
278 root 1.188 - Coro::Event blocking semantics have been changed,
279     documented and - hopefully - improved.
280 root 1.184 - fix nice adding, not subtracting, from priority.
281 root 1.185 - fix ->prio and api_is_ready (patch by Mark Hinds).
282 root 1.190 - fixed an assert ("... == prev__cctx->idle_te")
283     that could errronously trigger.
284 root 1.192 - fix various large and small memleaks.
285 root 1.191 - use a (hopefully) more stable cancel implementation
286     that immediately frees the coroutine data.
287 root 1.194 - cede/cede_notself return a status now.
288 root 1.191 - added Coro::guard function.
289 root 1.193 - added a global coroutine pool for jobs (on my machine,
290     I can create and execute 48k simple coros/s with async,
291     and 128k coros with async_pool).
292 root 1.195 - Coro::AIO now uses the coroutine priority as io priority.
293 root 1.184
294 root 1.183 3.2 Fri Dec 22 05:07:09 CET 2006
295 root 1.179 - improve portability to slightly older perls.
296 root 1.180 - use cleaner coroutine destruction.
297 root 1.182 - simplify configuration for users.
298     - optionally (unrecommended) prefer perl functions over
299     their coro replacements.
300 root 1.179
301 root 1.178 3.11 Tue Dec 5 13:11:24 CET 2006
302     - fixed some bogus assert's, but as perl.h disables assert even
303     without NDEBUG (thank you very much), not too many people should
304     notice (that did include myself). Andreas König noticed, though :)
305     - do not save/restore PL_sortcxix on >= 5.9.x, it doesn't seem to have
306     it. Also noticed by Andreas König :)
307     - save/restore tainted status.
308     - verified to pass the testsuite on my 5.9.5.
309    
310 root 1.177 3.1 Mon Dec 4 23:03:40 CET 2006
311     - INCOMPATIBLE CHANGE: $/ is now per-coroutine (but slow).
312 root 1.175 - incompatible change: transfer flags are now per-state.
313 root 1.173 - give a better error message on deadlock.
314 root 1.175 - document Coro::nready.
315 root 1.174 - enhanced testsuite.
316 root 1.169
317 root 1.172 3.01 Sun Dec 3 23:47:42 CET 2006
318     - forgot to include Coro::Timer.
319    
320 root 1.171 3.0 Sun Dec 3 22:57:25 CET 2006
321 root 1.163 - the "FINALLY COMPLETELY STABLE" release (coming soon:
322     the "FAMOUS LAST WORDS" release).
323 root 1.166 - implement a new stack sharing algorithm, which uses a stack
324     pool (size currently hardcoded).
325 root 1.155 - make stack sharing mandatory (it no longer uses a heuristic).
326 root 1.157 - eval/die no longer cause weird problems under heavy use.
327 root 1.152 - Coro::Event could cause livelocks if it was used but
328 root 1.161 no Coro::Event watchers were used.
329 root 1.167 - Coro::Event now uses asynccheck as prepare does not
330     check for changed watchers.
331 root 1.170 - Coro::Event allows multiple waiting coros and will wake up one
332     per event.
333 root 1.152 - Coro::Event should be cleaner and more efficient now.
334 root 1.165 - new utility function Coro::unblock_sub.
335 root 1.164 - document the sad fact that Event is no longer reentrant.
336 root 1.163 - putting a coroutine into the ready queue twice could under
337     some circumstances lead to stack corruption.
338 root 1.161 - minor incompatibility: subclassing Coro::State is supported
339     directly now without going through a _coro_state member.
340 root 1.156 - state/coro switching is much faster now.
341 root 1.154 - very minor optimisations and code/documentation cleanup.
342 root 1.153 - avoid problems due to compiler inlining.
343 root 1.154 - removed timers from Coro::Timer -> use AnyEvent instead.
344     - replaced Coro::idle coroutine by (cleaner) idle handler.
345 root 1.156 - updated to newest libcoro.
346 root 1.159 - implement enhanced support for valgrind.
347 root 1.162 - implement is_ready and return value for ready.
348 root 1.168 - removed Coro::Cont, it was a misnomer (it's generators),
349     and it was somewhat annoying to get it right. Will come back
350     if somebody asks for it :)
351 root 1.163 - many ->wait methods and Coro::Event could return
352     spuriously without the event having happened.
353 root 1.146
354 root 1.145 2.5 Tue Nov 7 12:22:33 CET 2006
355 root 1.143 - made Coro::Util, Coro::Select, Coro::Handle and Coro::Socket
356     use AnyEvent, moved them to Coro/.
357 root 1.140 - added Coro::LWP which contains all the uglyness required to
358     make LWP non-blocking.
359     - should work with perl 5.9.x now (Andreas König made me do it).
360 root 1.141 - fixed another bug in Coro::Select when the timeout was undef.
361 root 1.136 - reuse PL_start_env for all coros, saves some memory per coroutine.

454 pcg 1.91 - made Coro to work _better_ with threads (it seems that, as long
455     as you use Coros in one thread only everything will work fine.
456     Looking at the perl source the problem might be missing locking
457     between Coro and some perl internal routines. That's not easily
