# 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 1.314 - reset diehook when terminating from an async_pool as to not
9     trigger any __DIE__ handlers.
10    
11 root 1.313 4.35 Sun Jan 13 04:14:13 CET 2008
12 root 1.308 - "bt" debug command now displays any exceptions
13 root 1.311 from longmess and also skips the innermost
14     stackframes, giving more useufl output.
15 root 1.309 - allow backtraces in coroutines blocked in Coro::EV,
16 root 1.310 at a <1% speed hit.
17 root 1.312 - handle localising of $SIG{__WARN__} and __DIE__
18 root 1.314 properly (with a proper amount of dirty hacking).
19 root 1.308
20 root 1.307 4.34 Sat Dec 22 17:49:53 CET 2007
21 root 1.306 - upgrade to EV version 2.0 API.
22    
23 root 1.305 4.33 Mon Dec 17 08:36:12 CET 2007
24     - make Coro::AIO etc. loadable in the absence of EV.
25    
26 root 1.304 4.32 Mon Dec 17 07:46:02 CET 2007
27 root 1.301 - majorly improved Coro::Handle's performance with Coro::EV.
28 root 1.302 - implemented the until now mythical Coro::BDB module.
29 root 1.304 - specialcase EV in Coro::AIO and Coro::BDB for extra speed.
30 root 1.301
31 root 1.300 4.31 Wed Dec 5 12:32:39 CET 2007
32     - remove warn statement form Coro::Util.
33    
34 root 1.299 4.3 Tue Dec 4 20:33:14 CET 2007
35     - calls to the idle function could cause stack corruption
36     when the stack changed.
37 root 1.295 - do no longer rely on the presence of EV::DNS if EV is used
38     (because it is gone), but instead take avdantage of EV::ADNS
39     if available.
40 root 1.296 - add ($) prototypes to all functions in Coro::Storable.
41 root 1.297 - use a conventional (safer) idle callback in Coro::EV.
42 root 1.298 - do accept quickly in Coro::Debug to avoid endless loops.
43 root 1.295
44 root 1.294 4.22 Fri Nov 30 16:04:04 CET 2007
45 root 1.293 - really use optimised versions for Event and EV in Coro::Util
46     and Coro::Handle.
47    
48 root 1.292 4.21 Sun Nov 25 10:48:59 CET 2007
49 root 1.290 - fix a spurious memory read.
50 root 1.291 - Coro::EV no longer keeps the eventloop "alive".
51 root 1.290
52 root 1.289 4.2 Fri Nov 9 20:47:05 CET 2007
53 root 1.282 - enable/disable tracing from a new coroutine, not a pooled one.
54 root 1.283 - fix a memleak in Coro::Event.
55 root 1.284 - removed killall call from fork_eval.
56     - made sure store_fd is already loaded so that fork_eval
57     does not have to parse autoload in each subprocess.
58 root 1.288 - only use assembly method if -O switch is in $Config{optimize}.
59 root 1.289 - add (optional) Coro::EV module, so far the best event loop module
60     directly supported by Coro.
61     - if the event model is EV, use EV::DNS to resolve
62     stuff in Coro::Util.
63 root 1.286 - don't get confused by multiple event notifications in Coro::Handle.
64 root 1.287 - initial support for EV (libevent interface).
65 root 1.289 - require Event and EV using configure_requires, to force their existance.
66 root 1.282
67 root 1.281 4.13 Wed Oct 24 07:26:45 CEST 2007
68 root 1.277 - add Coro::Storable::blocking_thaw.
69 root 1.278 - use a vastly more complicated technique to localise
70     $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
71 root 1.279 - use a coroutine for the idle callback Coro::Event,
72     instead of running Event in the current coroutine context.
73     This also catches recursive invocations.
74 root 1.280 - actually report fork errors in gethostbyname and inet_aton.
75 root 1.277
76 root 1.276 4.11 Thu Oct 11 02:40:24 CEST 2007
77     - port to threaded perls.
78    
79 root 1.275 4.1 Thu Oct 11 02:38:16 CEST 2007
80 root 1.264 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
81     be local to each coro (see Coro::State).
82 root 1.274 - incompatible change: for very deep reasons, cede and cede_notself
83     cannot return anything, so nothing will be returned.
84 root 1.264 - possibly bring back 5.10 compatibility (untested).
85     - work around stupid (and wrong) warning on 5.10 :(.
86     - overlay the saved state over the context stack. This saves
87     a few hundred bytes per coroutine on average and also
88     speeds up context switching a bit.
89 root 1.265 - further tune default stack sizes.
90 root 1.264 - (more) correctly calculate stack usage in coro_rss.
91 root 1.267 - Coro::Storable::blocking_* did not properly lock
92     resulting in races between coroutines.
93     - added Coro::Storable::guard.
94 root 1.268 - stopping to trace a coroutine could destroy the cctx of
95     an unrelated coroutine.
96 root 1.269 - explain the relationship between Perl and C coroutines in
97     more detail in Coro::State.
98 root 1.270 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
99     causing a fork per resolve. This also affected Coro::Socket.
100 root 1.272 - switch to a separate stack in $coro->call/eval to avoid
101     invalidating pointers.
102 root 1.264
103 root 1.263 4.03 Sat Oct 6 21:24:00 CEST 2007
104 root 1.262 - added Coro::throw method.
105     - minor code cleanups.
106    
107 root 1.261 4.02 Sat Oct 6 02:36:47 CEST 2007
108 root 1.258 - fix a very minor per-coroutine memleak (a single codereference).
109 root 1.259 - fixed a bug where the currently in-use c context would be freed
110     prematurely (can happen only when programs change the stacksize
111     or use tracing).
112     - tracing can no longer keep a coro alive after it terminated.
113 root 1.260 - do static branch prediction in the common path for gcc. gives
114     about 2-5% speed improvement here.
115 root 1.258
116 root 1.256 4.01 Fri Oct 5 22:10:49 CEST 2007
117 root 1.257 - instead of recreating *a* standard output handle we simply
118     use STDOUT, which is faster and hopefully more robust.
119 root 1.255
120 root 1.254 4.0 Fri Oct 5 12:56:00 CEST 2007
121 root 1.238 - incompatibly changed Coro::Storable::freeze.
122 root 1.244 - major new feature: added Coro::Debug, for interactive coroutine
123     debugging, tracing and much more.
124 root 1.252 - major bug fix: unbelievable, but true: $_, $/ and many other
125     "saved" variables actually weren't being saved. This has been fixed,
126     of course, while increasing performance while losing all the save
127     flags.
128 root 1.251 - save flags are gone, and all the api functions dealing with them.
129 root 1.232 - added Coro::Semaphore::adjust.
130 root 1.233 - added Coro::Util::fork_eval.
131     - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
132 root 1.248 - added Coro::killall.
133 root 1.236 - reduce initial stack sizes to allow for "micro-coroutines".
134 root 1.239 - better async_pool resource management, moved parts of async_pool
135 root 1.240 handling to XS (major speed improvement).
136 root 1.245 - actually croak before modifying important data structures.
137     - refuse to transfer while compiling.
138     - possibly support eval EXPR better now.
139 root 1.249 - enable assembly per default on linux+bsd x86+amd64.
140 root 1.253 - all internal members were renamed _something for easier subclassing.
141 root 1.237 - many minor tweaks.
142 root 1.232
143 root 1.231 3.63 Wed May 16 14:10:06 CEST 2007
144 root 1.230 - implement handcoded assembly for x86/amd64 SVR ABI.
145    
146 root 1.229 3.62 Fri Apr 27 21:36:06 CEST 2007
147     - upgrade libcoro (which might set unwind info correctly).
148 root 1.228 - change default on linux to setjmp/longjmp.
149 root 1.227
150 root 1.226 3.61 Thu Apr 19 12:36:18 CEST 2007
151 root 1.225 - Coro::Storable caused an endless loop when thawing invalid
152     pst's sometimes.
153 root 1.223 - use a Semaphore in Coro::Storable, as Storable doesn't
154 root 1.224 seem to be reentrant (although it is documented to
155     be threadsafe...).
156     - fix Coro::Signal to bring back the original unreliable
157     but stateful semantics.
158 root 1.226 - fixed a lot of typos in Coro.pm (patch submitted by David
159     Steinbrunner, which applied flawlessly).
160 root 1.223
161     3.6 Sat Apr 14 17:13:31 CEST 2007
162 root 1.217 - added some bugfixes to get eg/myhttpd working again.
163 root 1.218 - added Coro::Storable for often-cede'ing freeze/thaw.
164 root 1.219 - try to do a clean exit when a coroutine calls exit
165     (EXPERIMENTAL).
166 root 1.220 - got rid of indirect call through _coro_init.
167     - updated the partly antique examples in eg/ to
168     work again and be a bit less magic, too.
169     - fixed Coro::Signal semantics to work as documented again.
170 root 1.217
171 root 1.216 3.55 Sun Mar 25 01:20:47 CET 2007
172 root 1.215 - add SAVE_DEFFH to save the default filehandle and enable
173     it by default.
174     - finally move socket-operations from Coro::Socket to Coro::Handle
175     to be able to unblock foreign sockets.
176     - add Coro::State::save_also and guarded_save.
177 root 1.211 - add count accessor to Coro::Semaphore.
178 root 1.212 - add Coro::State::cctx_stacksize.
179 root 1.213 - just for the fun of it, do not rely on implicit context,
180     which can dramatically improve performance, but people
181     using windows-process-emulation perls do not care much about
182     performance.
183 root 1.211
184 root 1.210 3.51 Sun Mar 4 14:18:04 CET 2007
185 root 1.209 - fixed a problem when you weakened references to Coro::State's
186     (patch by Yuval Kogman).
187    
188 root 1.208 3.501 Wed Feb 28 12:44:07 CET 2007
189     - rename some global symbols as macosx from hell redefines
190     them without asking.
191    
192 root 1.207 3.5 Tue Feb 13 20:22:53 CET 2007
193 root 1.204 - do AnyEvent model detection earlier, avoiding problems
194     caused by first using AnyEvent and later Coro::Event.
195 root 1.205 - implement and document Coro::Event event objects.
196     - fix a potential problem in Coro::Event causing crashes.
197 root 1.206 - initialise PL_comppad when creating a new coroutine,
198     avoids crashes on early coro destruction.
199 root 1.204
200 root 1.203 3.41 Mon Jan 22 19:19:49 CET 2007
201 root 1.202 - readline on Coro::Handle did not support undefined $/,
202     nor did it deliver partial lines on EOF or error.
203 root 1.203 - implement malloc fallback for stack allocation because
204     stupid broken idiotic OSX has a stupid broken
205     idiotic fits-the-whole-os mmap "implementation" and
206     my dick feels longer if Coro is portable even to
207     obsolete platforms.
208 root 1.202
209 root 1.201 3.4 Fri Jan 19 21:52:54 CET 2007
210 root 1.197 - remove t/09_timer.t, as it isn't really testing much
211     but was rather flaky in practise.
212 root 1.198 - async_pool coro would keep arguments and callback alive until
213     it was reused.
214 root 1.199 - cancellation of a coroutine could cause spurious idle calls
215     in cede_notself.
216 root 1.197
217 root 1.196 3.3 Sat Jan 6 03:45:00 CET 2007
218 root 1.187 - implement $coro->on_destroy.
219 root 1.188 - Coro::Event blocking semantics have been changed,
220     documented and - hopefully - improved.
221 root 1.184 - fix nice adding, not subtracting, from priority.
222 root 1.185 - fix ->prio and api_is_ready (patch by Mark Hinds).
223 root 1.190 - fixed an assert ("... == prev__cctx->idle_te")
224     that could errronously trigger.
225 root 1.192 - fix various large and small memleaks.
226 root 1.191 - use a (hopefully) more stable cancel implementation
227     that immediately frees the coroutine data.
228 root 1.194 - cede/cede_notself return a status now.
229 root 1.191 - added Coro::guard function.
230 root 1.193 - added a global coroutine pool for jobs (on my machine,
231     I can create and execute 48k simple coros/s with async,
232     and 128k coros with async_pool).
233 root 1.195 - Coro::AIO now uses the coroutine priority as io priority.
234 root 1.184
235 root 1.183 3.2 Fri Dec 22 05:07:09 CET 2006
236 root 1.179 - improve portability to slightly older perls.
237 root 1.180 - use cleaner coroutine destruction.
238 root 1.182 - simplify configuration for users.
239     - optionally (unrecommended) prefer perl functions over
240     their coro replacements.
241 root 1.179
242 root 1.178 3.11 Tue Dec 5 13:11:24 CET 2006
243     - fixed some bogus assert's, but as perl.h disables assert even
244     without NDEBUG (thank you very much), not too many people should
245     notice (that did include myself). Andreas König noticed, though :)
246     - do not save/restore PL_sortcxix on >= 5.9.x, it doesn't seem to have
247     it. Also noticed by Andreas König :)
248     - save/restore tainted status.
249     - verified to pass the testsuite on my 5.9.5.
250    
251 root 1.177 3.1 Mon Dec 4 23:03:40 CET 2006
252     - INCOMPATIBLE CHANGE: $/ is now per-coroutine (but slow).
253 root 1.175 - incompatible change: transfer flags are now per-state.
254 root 1.173 - give a better error message on deadlock.
255 root 1.175 - document Coro::nready.
256 root 1.174 - enhanced testsuite.
257 root 1.169
258 root 1.172 3.01 Sun Dec 3 23:47:42 CET 2006
259     - forgot to include Coro::Timer.
260    
261 root 1.171 3.0 Sun Dec 3 22:57:25 CET 2006
262 root 1.163 - the "FINALLY COMPLETELY STABLE" release (coming soon:
263     the "FAMOUS LAST WORDS" release).
264 root 1.166 - implement a new stack sharing algorithm, which uses a stack
265     pool (size currently hardcoded).
266 root 1.155 - make stack sharing mandatory (it no longer uses a heuristic).
267 root 1.157 - eval/die no longer cause weird problems under heavy use.
268 root 1.152 - Coro::Event could cause livelocks if it was used but
269 root 1.161 no Coro::Event watchers were used.
270 root 1.167 - Coro::Event now uses asynccheck as prepare does not
271     check for changed watchers.
272 root 1.170 - Coro::Event allows multiple waiting coros and will wake up one
273     per event.
274 root 1.152 - Coro::Event should be cleaner and more efficient now.
275 root 1.165 - new utility function Coro::unblock_sub.
276 root 1.164 - document the sad fact that Event is no longer reentrant.
277 root 1.163 - putting a coroutine into the ready queue twice could under
278     some circumstances lead to stack corruption.
279 root 1.161 - minor incompatibility: subclassing Coro::State is supported
280     directly now without going through a _coro_state member.
281 root 1.156 - state/coro switching is much faster now.
282 root 1.154 - very minor optimisations and code/documentation cleanup.
283 root 1.153 - avoid problems due to compiler inlining.
284 root 1.154 - removed timers from Coro::Timer -> use AnyEvent instead.
285     - replaced Coro::idle coroutine by (cleaner) idle handler.
286 root 1.156 - updated to newest libcoro.
287 root 1.159 - implement enhanced support for valgrind.
288 root 1.162 - implement is_ready and return value for ready.
289 root 1.168 - removed Coro::Cont, it was a misnomer (it's generators),
290     and it was somewhat annoying to get it right. Will come back
291     if somebody asks for it :)
292 root 1.163 - many ->wait methods and Coro::Event could return
293     spuriously without the event having happened.
294 root 1.146
295 root 1.145 2.5 Tue Nov 7 12:22:33 CET 2006
296 root 1.143 - made Coro::Util, Coro::Select, Coro::Handle and Coro::Socket
297     use AnyEvent, moved them to Coro/.
298 root 1.140 - added Coro::LWP which contains all the uglyness required to
299     make LWP non-blocking.
300     - should work with perl 5.9.x now (Andreas König made me do it).
301 root 1.141 - fixed another bug in Coro::Select when the timeout was undef.
302 root 1.136 - reuse PL_start_env for all coros, saves some memory per coroutine.
303     - manage PL_top_env differently, hopefully to avoid panic: top_env.
304 root 1.137 - timeout argument was not properly used in Coro::Socket.
305     - allow limited forms of subclassing in Coro::Handle/Coro::Socket.
306 root 1.138 - emulate undocumented(!) functionality of IO::Socket required
307     by LWP(!!).
308     - updated eg/lwp to work with newer lwp's.
309 root 1.140 - remove "FATAL: uncaught exception" prefix. Coroutines that die
310     kill the whole process, just as exceptions in the main "coroutine"
311     did already.
312 root 1.135
313 root 1.134 2.1 Wed Nov 1 23:01:13 CET 2006
314     - fix a long-standing bug in Coro::Select where select with
315     zero timeout would instead change the current default filehandle.
316 root 1.132 - use a simpler and hopefully more robust way to clone padlists
317     (uses less memory and a perl function instead of our own).
318     - coro can now create a stack guard area on many architectures.
319 root 1.134 - Coro::AIO properly reexports additional functions from IO::AIO.
320 root 1.132 - updated libcoro with a workaround for OS X,
321 root 1.134 pach and testing by Michael Schwern.
322 root 1.130
323 root 1.129 2.0 Tue Oct 24 05:47:17 CEST 2006
324 root 1.128 - support additional aio requests in Coro::AIO.
325    
326 root 1.129 1.9 (never properly released due to a glitch)
327    
328 root 1.127 1.8 Thu Feb 2 00:59:06 CET 2006
329 root 1.125 - applied suggested patch by SAMV to avoid problems during stupid
330     mark & sweep gc run.
331 root 1.126 - applied patch by Scott Walters for 5.9.3 compatibility.
332 root 1.125
333 root 1.124 1.7 Tue Dec 27 01:41:58 CET 2005
334 root 1.123 - added Coro::AIO, a thin wrapper around IO::AIO.
335 root 1.122 - improved Makefile.PL explanations.
336    
337 root 1.119 1.6 Mon Dec 12 21:30:05 CET 2005
338 root 1.117 - additionally save PM_curpm might fix as-of-yet
339 root 1.121 unseen problems with regex matches being attributed to the
340 root 1.117 wrong package.
341 root 1.118 - add t/10_bugs.t, which currently checks against imho broken
342     perls that use 0.26MB of stack space per Perl_magic_get
343 root 1.121 invocation (newer linuxes) as opposed to the 0.0002MB perl
344     normally uses.
345 root 1.120 - make stacksize configurable for the ultimate debian experience.
346 root 1.117
347 root 1.116 1.51 Mon Dec 12 18:48:36 CET 2005
348     - remove debugging warn() accidentally left in Coro::Select.
349    
350 root 1.115 1.5 Tue Nov 29 13:32:44 CET 2005
351 root 1.114 - use Coro::Event inside Coro::Select to avoid spurious deadlocks.
352 root 1.115 - fix Coro::Select 'select'.
353     - strict'ify some modules.
354 root 1.112 - libcoro errornously restored the SIGUSR2 handler to SIGUSR1.
355 root 1.115 - use XSLoader in selected modules.
356     - remove some 5.6 compatibility cruft.
357 root 1.112
358 root 1.111 1.4 Tue Sep 6 00:11:05 CEST 2005
359     - libcoro did not take into account the trampoline on amd64,
360     when 'l'inux method was used.
361    
362 root 1.110 1.31 Tue Aug 30 23:31:33 CEST 2005
363     - some portability fixes/workarounds.
364    
365 root 1.107 1.3 Sat Aug 20 03:08:56 CEST 2005
366 root 1.108 - no code changes. module seems to work fine.
367 root 1.106 - improve Coro::State docs, remove reference to nonexisting
368     Coro::State::flush method.
369 root 1.107 - no longer autodetect windows, present it as an option instead.
370 root 1.106
371 root 1.105 1.2 Mon May 16 02:00:55 CEST 2005
372 root 1.100 - included libcoro.c earlier in State.xs, might improve portability.
373 root 1.101 - use a faster and possibly more stable Coro::Cont implementation.
374 root 1.102 - accept x86_64 in addition to amd64 for optimized linux-amd64 support.
375 root 1.104 - fix bugs Coro::SemaphoreSet that could cause locks never to be freed.
376 root 1.105 - fix bugs in CoroAPI.h and document it in Coro::MakeMaker.
377 root 1.100
378 root 1.99 1.11 Thu Mar 3 18:00:52 CET 2005
379     - change of contact address.
380    
381 root 1.98 1.1 Tue Feb 22 20:51:16 CET 2005
382 root 1.97 - support [l]inux method on amd64.
383 root 1.109 - allow some context switches while compiling/eval'ing.
384 root 1.97
385 root 1.96 1.0 Tue Aug 10 03:47:27 CEST 2004
386 root 1.95 - Event 0.89 fixes the bug again.
387 root 1.96 - fix the remaining(??) memleak. I didn't free the cache-AV for
388     padlists, so one AV per created anon-sub leaked.
389 root 1.95
390 pcg 1.94 0.97 Fri May 14 15:23:32 CEST 2004
391     - remove stupid gcc extension that was an experiment only anyway.
392    
393 pcg 1.93 0.96 Thu May 13 18:09:29 CEST 2004
394 root 1.103 - tell people if they have yet another broken Event variant.
395 pcg 1.91 - made Coro to work _better_ with threads (it seems that, as long
396     as you use Coros in one thread only everything will work fine.
397     Looking at the perl source the problem might be missing locking
398     between Coro and some perl internal routines. That's not easily
399     fixable).
400 pcg 1.92 - (hopefully) got rid of the static xnext inside transfer.
401 pcg 1.91
402 pcg 1.90 0.95 Sun Feb 15 03:20:28 CET 2004
403 pcg 1.86 - removed Coro::State::flush, implemented a new and much
404     faster caching mechanism by attaching magic to the CV.
405 pcg 1.87 - a memleak with (real) closures remains.
406 pcg 1.88 - dramatically reduced size of stacks to 65536 (linux/x86), after
407     observing that even myhttpd never had more than a kilobyte
408     of stack in use (stack is still only physically allocated in
409     pagesize increments for systems suporting mmap).
410 pcg 1.89 - fix for a "cygwin-64" architecture added, proposed by Stefan Traby.
411 pcg 1.90 - fix for threaded perl.
412 pcg 1.86
413 pcg 1.85 0.9 Sun Nov 23 04:32:39 CET 2003
414 pcg 1.84 - fix a few very hard to track down but (of course) stupid
415     memory leaks.
416     - stringify version number to avoid locale problems :(.
417 pcg 1.85 - perl 5.9.0 does not have SvPADBUSY, reported by Scott Walters,
418     hopefully ignoring it "just works".
419 pcg 1.84
420 pcg 1.83 0.8 Wed Nov 5 19:38:40 CET 2003
421     - port to perl5.005_03, but only 5.8.x+ is supported!
422 pcg 1.82 - honor LocalAddr even without LocalPort in Coro::Socket.
423    
424 root 1.81 0.7 Tue May 27 03:12:38 CEST 2003
425     - the version jump indicates some level of testing, not gobs
426     of new features.
427 root 1.80 - uh... I found the prompt function in ExtUtils::MakeMaker.
428     Highly correct stuff, that is...
429 root 1.81 - fixed(?) a bug with die's in coroutines causing "panic: top_env".
430     the fix is not well understood by the author, so beware :(.
431 root 1.80
432 root 1.79 0.652 Thu May 8 02:54:46 CEST 2003
433 root 1.76 - Applied patch by Slaven Rezic to set default to "s" on FreeBSD,
434 root 1.78 cause version 4 doesn't have ucontext.
435 root 1.77 - Benjamin Reed reported that setjmp works fine on darwin,
436     so preselect it.
437 root 1.76
438 root 1.75 0.651 Sat Mar 29 15:00:23 CET 2003
439     - fix a bug in Coro::Handle where some bytes could get lost
440     on reading, reported by jason@nichego.net.
441 root 1.74
442 root 1.73 0.65 Sun Mar 23 00:08:26 CET 2003
443 root 1.72 - added a README.linux-glibc.
444     - new module Coro::Select.
445     - also save/restore PL_comppad, fixes segfaults with 5.8.1.
446     (I never claimed that I know what I am doing ;).
447 root 1.73 - set default to setjmp/longjmp on non-x86-linux.
448 root 1.72
449 root 1.71 0.6 Thu Nov 21 11:09:06 CET 2002
450     - made lazy context switching the default.
451     - fixed the bug where SemaphoreSet::guard
452     was the same as timed_guard and timed_guard was missing.
453     - fix a memleak in Coro::Timer.
454     - reclassified context sharing as not experimental.
455    
456 root 1.70 0.534 Sun Apr 14 03:05:12 CEST 2002
457 root 1.69 - fixed backspace => tab in header parsing (myhttpd).
458 root 1.70 - added eg/readline, for elmex.
459     - Coro::Event now calls ->start on first call instead of
460     ->again, which created wrong timeouts for the first ->next.
461     - fixed a bug where Coro::Socket returned a closed socket instead
462     of nothing on ECONNREFUSED and similar error conditions.
463 root 1.69
464 root 1.68 0.533 Mon Feb 18 18:49:40 CET 2002
465     - adapt to finally working Event-0.85.
466     - fixed buggy event initialization (trapped under windows, but how
467     could it possibly have worked anywhere?)
468    
469 root 1.67 0.532 Wed Jan 16 02:45:32 CET 2002
470 root 1.66 - removed the reference to pp_entersub, might work on
471     (some) win32 perls now (testsuite works under cygwin,
472     without Event, which freezes).
473 root 1.65
474 root 1.64 0.531 Mon Dec 10 22:18:44 CET 2001
475 root 1.63 - Fixed a bug in SemaphoreSet::timed_down.
476    
477 root 1.64 0.53 Tue Nov 27 21:11:13 CET 2001
478 root 1.60 - some tests for Event.
479 root 1.61 - slightly different internal architecture to get refcnt into the object
480     and not the reference. might fix a few bugs, certainly did introduce
481     new ones.
482     - Coro::Timer (independent of Event).
483 root 1.62 - new timed_wait functions for Coro::Signal, Semaphore, SemaphoreSet.
484 root 1.60
485 root 1.64 0.52 Tue Nov 6 21:36:18 CET 2001
486 root 1.58 - ported to cygwin (trivial).
487     patch by Gerrit P. Haase <gp@familiehaase.de>.
488     - small setjmp code fix by Sullivan.DanielJ@epamail.epa.gov.
489    
490 root 1.64 0.51 Thu Nov 1 20:39:01 CET 2001
491 root 1.54 - terminate/cancel now work properly (otherwise termination
492     could cause a "next coroutine is not and contains not..."
493     error.
494 root 1.55 - added Coro::Socket::shutdown.
495 root 1.56 - Coro::Event::loop no is the same as Event::loop.
496     - implemented terminate with args + join.
497 root 1.54
498 root 1.64 0.5 Fri Sep 28 16:15:35 CEST 2001
499 root 1.53 - fixed "print" on a Coro::Handle. The print method worked.
500 root 1.50 - small tweaks (seem to reduce memory consumption a lot)
501     in various modules.
502     - splendid use of "no warnings" scattered throughout.
503 root 1.52 - added Coro::Handle::rbuf, fixed Coro::Handle::fh.
504 root 1.48
505 root 1.47 0.49 Sun Sep 16 02:42:45 CEST 2001
506 root 1.43 - changed some method calls to function calls for speed
507     inside Coro::Handle.
508 root 1.44 - make Coro::Handle use an array instead of a hash for
509     speed reasons.
510     - IRIX mystery solved: it's SGI's NT, after all: "standard, huh?".
511     sjlj and ucontext should now work.
512     - IRIX-specific port for libcoro.
513 root 1.45 - swapped order of accept results to match IO::Socket.
514 root 1.46 - changed getsock/peername to sock/peername to match IO::Socket.
515     - fixed a bug that caused segfault when returning to main task
516     under some circumstances.
517     - other bugfixes.
518 root 1.43
519 root 1.42 0.45 Sun Sep 2 02:54:01 CEST 2001
520 root 1.36 - new method Coro::Handle::timeout.
521     - corrected speling of set...name to get...name in Coro::Socket.
522     - Coro::Socket::accept now returns a Coro::Socket, not a Coro::Handle.
523     - Coro::Handle now supports fileno and FILENO.
524     - added eg/myhttpd, a web server.
525 root 1.37 - Coro::Socket now accepts numeric ports as well as "port(number)"
526     syntax.
527 root 1.38 - moved some scheduling primitives into xs code. more to come.
528 root 1.39 - new simple priority system.
529 root 1.40 - implemented Coro::Event using XS, almost four times faster!
530 root 1.41 - small memory corruption problem fixed (boy that was difficult).
531 root 1.36
532 root 1.35 0.13 Wed Aug 8 16:53:07 CEST 2001
533 root 1.31 - new method Coro::Handle::readline.
534 root 1.34 - added eg/lwp and Coro::Handle::autoflush, to make LWP work.
535     (see eg/lwp on how to make LWP non-blocking).
536 root 1.31 - renamed Coro::Socket::new_inet to new.
537 root 1.32 - added Coro::Util, some utility functions.
538 root 1.33 - die/eval now works better (still get annoying (but true ;)
539     "Callback called exit" messages).
540 root 1.34 - Coro::Handle now supports timeout, and Coro::Socket Timeout.
541     - much better Coro::Socket support.
542 root 1.31
543     0.12 Fri Jul 27 04:19:01 CEST 2001
544 root 1.29 - do not use mmap if neither MAP_ANON nor MAP_ANONYMOUS is defined.
545 root 1.34 - very experimental stack sharing algorithm. not 100% safe but
546 root 1.28 should work well in practise ;)
547 root 1.30 - added Coro::RWLock.
548 root 1.31 - Coro::Specific now works.
549 root 1.28
550     0.11 Tue Jul 24 22:49:21 CEST 2001

554    
555 root 1.26 0.1 Tue Jul 24 01:47:53 CEST 2001
556 root 1.23 - release candidate 3. A rather new internal structure :(
557 root 1.24 - the great renaming: Damian Conway gave me a suitable replacement
558     for yield.
559 root 1.23 - added Coro/libcoro, a portable coroutine implementation for C
560 root 1.22 (not even perl-dependent!!!), which can be used by Coro::State.
561 root 1.20 - renamed SAVE_DEFSV (on xs-level only) to avoid symbol clash in
562     perl-5.6.
563 root 1.16 - new function Coro::Event::idle.
564     - the idle process is now overriden
565     by default in Coro::Event.

567 root 1.18 - canceling events now works in all cases.
568 root 1.19 - Coro state now include $_ and $@.

570 root 1.21 - new module Coro::Event::IO (very undocumented) to do
571     non-blocking i/o.
572 root 1.25 - performance tuning.
573 root 1.16
574 root 1.15 0.08 Thu Jul 19 06:13:25 CEST 2001
575 root 1.14 - release candidate 2 (new functionality).
576 root 1.13 - add Coro::State::flush function.
577     - transfer now supports a flags value (mostly for speed ATM).
578     - might compile and work in the presence of threads now.

580 root 1.19 - no more memleaks.
581 root 1.13
582 root 1.12 0.07 Tue Jul 17 17:40:18 CEST 2001
583     - release candidate 1 ;)
584     - slightly nicer code.
585     - fixed a scheduling bug in Coro::Event.
586    
587 root 1.11 0.06 Tue Jul 17 04:23:24 CEST 2001
588     - ok, I found the showstopper - the same sub must not be
589 root 1.9 re-entered in two different coroutines, otherwise => crash. I
590     see no easy solution to this problem, except by walking the call
591     chaing and saving/restoring the cv's, which is what I do now.
592 root 1.11 - memory leaks still latent, especially at thread termination.
593     - Coro::Event now works (haha).
594 root 1.9
595 root 1.8 0.05 Sun Jul 15 17:32:20 CEST 2001
596     - fixed a few issues in Coro::Event.

600 root 1.5 - @_ is now properly localized.
601 root 1.4 - Coro::State is now easier subclassable.
602     - Coro::Cont now coroutine-aware.
603     - Coro::Specific is a low-overhead module to create
604     coroutine-specific vars.

606 root 1.4
607 root 1.3 0.03 Fri Jul 13 14:51:52 CEST 2001
608 root 1.4 - transfer() now implemented in XS (beware).
609     - new module Coro::Cont for really faked continuations.
610     - big internal architecture changes: Coro::State is now
611 root 1.3 really low-level and can thus be used to implement other
612 root 1.4 interesting things, While "Coro::" implements a process-like
613     model. Still crude and subject to change.
614 root 1.3 - $_ and $@ are no longer being localized.
615    
616 root 1.2 0.02 Tue Jul 10 01:38:17 CEST 2001
