# 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 1.302 4.32
9 root 1.301 - majorly improved Coro::Handle's performance with Coro::EV.
10 root 1.302 - implemented the until now mythical Coro::BDB module.
11 root 1.303 - specialcase EV in Coro::AIO and Coro::BDB.
12 root 1.301
13 root 1.300 4.31 Wed Dec 5 12:32:39 CET 2007
14     - remove warn statement form Coro::Util.
15    
16 root 1.299 4.3 Tue Dec 4 20:33:14 CET 2007
17     - calls to the idle function could cause stack corruption
18     when the stack changed.
19 root 1.295 - do no longer rely on the presence of EV::DNS if EV is used
20     (because it is gone), but instead take avdantage of EV::ADNS
21     if available.
22 root 1.296 - add ($) prototypes to all functions in Coro::Storable.
23 root 1.297 - use a conventional (safer) idle callback in Coro::EV.
24 root 1.298 - do accept quickly in Coro::Debug to avoid endless loops.
25 root 1.295
26 root 1.294 4.22 Fri Nov 30 16:04:04 CET 2007
27 root 1.293 - really use optimised versions for Event and EV in Coro::Util
28     and Coro::Handle.
29    
30 root 1.292 4.21 Sun Nov 25 10:48:59 CET 2007
31 root 1.290 - fix a spurious memory read.
32 root 1.291 - Coro::EV no longer keeps the eventloop "alive".
33 root 1.290
34 root 1.289 4.2 Fri Nov 9 20:47:05 CET 2007
35 root 1.282 - enable/disable tracing from a new coroutine, not a pooled one.
36 root 1.283 - fix a memleak in Coro::Event.
37 root 1.284 - removed killall call from fork_eval.
38     - made sure store_fd is already loaded so that fork_eval
39     does not have to parse autoload in each subprocess.
40 root 1.288 - only use assembly method if -O switch is in $Config{optimize}.
41 root 1.289 - add (optional) Coro::EV module, so far the best event loop module
42     directly supported by Coro.
43     - if the event model is EV, use EV::DNS to resolve
44     stuff in Coro::Util.
45 root 1.286 - don't get confused by multiple event notifications in Coro::Handle.
46 root 1.287 - initial support for EV (libevent interface).
47 root 1.289 - require Event and EV using configure_requires, to force their existance.
48 root 1.282
49 root 1.281 4.13 Wed Oct 24 07:26:45 CEST 2007
50 root 1.277 - add Coro::Storable::blocking_thaw.
51 root 1.278 - use a vastly more complicated technique to localise
52     $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
53 root 1.279 - use a coroutine for the idle callback Coro::Event,
54     instead of running Event in the current coroutine context.
55     This also catches recursive invocations.
56 root 1.280 - actually report fork errors in gethostbyname and inet_aton.
57 root 1.277
58 root 1.276 4.11 Thu Oct 11 02:40:24 CEST 2007
59     - port to threaded perls.
60    
61 root 1.275 4.1 Thu Oct 11 02:38:16 CEST 2007
62 root 1.264 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
63     be local to each coro (see Coro::State).
64 root 1.274 - incompatible change: for very deep reasons, cede and cede_notself
65     cannot return anything, so nothing will be returned.
66 root 1.264 - possibly bring back 5.10 compatibility (untested).
67     - work around stupid (and wrong) warning on 5.10 :(.
68     - overlay the saved state over the context stack. This saves
69     a few hundred bytes per coroutine on average and also
70     speeds up context switching a bit.
71 root 1.265 - further tune default stack sizes.
72 root 1.264 - (more) correctly calculate stack usage in coro_rss.
73 root 1.267 - Coro::Storable::blocking_* did not properly lock
74     resulting in races between coroutines.
75     - added Coro::Storable::guard.
76 root 1.268 - stopping to trace a coroutine could destroy the cctx of
77     an unrelated coroutine.
78 root 1.269 - explain the relationship between Perl and C coroutines in
79     more detail in Coro::State.
80 root 1.270 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
81     causing a fork per resolve. This also affected Coro::Socket.
82 root 1.272 - switch to a separate stack in $coro->call/eval to avoid
83     invalidating pointers.
84 root 1.264
85 root 1.263 4.03 Sat Oct 6 21:24:00 CEST 2007
86 root 1.262 - added Coro::throw method.
87     - minor code cleanups.
88    
89 root 1.261 4.02 Sat Oct 6 02:36:47 CEST 2007
90 root 1.258 - fix a very minor per-coroutine memleak (a single codereference).
91 root 1.259 - fixed a bug where the currently in-use c context would be freed
92     prematurely (can happen only when programs change the stacksize
93     or use tracing).
94     - tracing can no longer keep a coro alive after it terminated.
95 root 1.260 - do static branch prediction in the common path for gcc. gives
96     about 2-5% speed improvement here.
97 root 1.258
98 root 1.256 4.01 Fri Oct 5 22:10:49 CEST 2007
99 root 1.257 - instead of recreating *a* standard output handle we simply
100     use STDOUT, which is faster and hopefully more robust.
101 root 1.255
102 root 1.254 4.0 Fri Oct 5 12:56:00 CEST 2007
103 root 1.238 - incompatibly changed Coro::Storable::freeze.
104 root 1.244 - major new feature: added Coro::Debug, for interactive coroutine
105     debugging, tracing and much more.
106 root 1.252 - major bug fix: unbelievable, but true: $_, $/ and many other
107     "saved" variables actually weren't being saved. This has been fixed,
108     of course, while increasing performance while losing all the save
109     flags.
110 root 1.251 - save flags are gone, and all the api functions dealing with them.
111 root 1.232 - added Coro::Semaphore::adjust.
112 root 1.233 - added Coro::Util::fork_eval.
113     - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
114 root 1.248 - added Coro::killall.
115 root 1.236 - reduce initial stack sizes to allow for "micro-coroutines".
116 root 1.239 - better async_pool resource management, moved parts of async_pool
117 root 1.240 handling to XS (major speed improvement).
118 root 1.245 - actually croak before modifying important data structures.
119     - refuse to transfer while compiling.
120     - possibly support eval EXPR better now.
121 root 1.249 - enable assembly per default on linux+bsd x86+amd64.
122 root 1.253 - all internal members were renamed _something for easier subclassing.
123 root 1.237 - many minor tweaks.
124 root 1.232
125 root 1.231 3.63 Wed May 16 14:10:06 CEST 2007
126 root 1.230 - implement handcoded assembly for x86/amd64 SVR ABI.
127    
128 root 1.229 3.62 Fri Apr 27 21:36:06 CEST 2007
129     - upgrade libcoro (which might set unwind info correctly).
130 root 1.228 - change default on linux to setjmp/longjmp.
131 root 1.227
132 root 1.226 3.61 Thu Apr 19 12:36:18 CEST 2007
133 root 1.225 - Coro::Storable caused an endless loop when thawing invalid
134     pst's sometimes.
135 root 1.223 - use a Semaphore in Coro::Storable, as Storable doesn't
136 root 1.224 seem to be reentrant (although it is documented to
137     be threadsafe...).
138     - fix Coro::Signal to bring back the original unreliable
139     but stateful semantics.
140 root 1.226 - fixed a lot of typos in Coro.pm (patch submitted by David
141     Steinbrunner, which applied flawlessly).
142 root 1.223
143     3.6 Sat Apr 14 17:13:31 CEST 2007
144 root 1.217 - added some bugfixes to get eg/myhttpd working again.
145 root 1.218 - added Coro::Storable for often-cede'ing freeze/thaw.
146 root 1.219 - try to do a clean exit when a coroutine calls exit
147     (EXPERIMENTAL).
148 root 1.220 - got rid of indirect call through _coro_init.
149     - updated the partly antique examples in eg/ to
150     work again and be a bit less magic, too.
151     - fixed Coro::Signal semantics to work as documented again.
152 root 1.217
153 root 1.216 3.55 Sun Mar 25 01:20:47 CET 2007
154 root 1.215 - add SAVE_DEFFH to save the default filehandle and enable
155     it by default.
156     - finally move socket-operations from Coro::Socket to Coro::Handle
157     to be able to unblock foreign sockets.
158     - add Coro::State::save_also and guarded_save.
159 root 1.211 - add count accessor to Coro::Semaphore.
160 root 1.212 - add Coro::State::cctx_stacksize.
161 root 1.213 - just for the fun of it, do not rely on implicit context,
162     which can dramatically improve performance, but people
163     using windows-process-emulation perls do not care much about
164     performance.
165 root 1.211
166 root 1.210 3.51 Sun Mar 4 14:18:04 CET 2007
167 root 1.209 - fixed a problem when you weakened references to Coro::State's
168     (patch by Yuval Kogman).
169    
170 root 1.208 3.501 Wed Feb 28 12:44:07 CET 2007
171     - rename some global symbols as macosx from hell redefines
172     them without asking.
173    
174 root 1.207 3.5 Tue Feb 13 20:22:53 CET 2007
175 root 1.204 - do AnyEvent model detection earlier, avoiding problems
176     caused by first using AnyEvent and later Coro::Event.
177 root 1.205 - implement and document Coro::Event event objects.
178     - fix a potential problem in Coro::Event causing crashes.
179 root 1.206 - initialise PL_comppad when creating a new coroutine,
180     avoids crashes on early coro destruction.
181 root 1.204
182 root 1.203 3.41 Mon Jan 22 19:19:49 CET 2007
183 root 1.202 - readline on Coro::Handle did not support undefined $/,
184     nor did it deliver partial lines on EOF or error.
185 root 1.203 - implement malloc fallback for stack allocation because
186     stupid broken idiotic OSX has a stupid broken
187     idiotic fits-the-whole-os mmap "implementation" and
188     my dick feels longer if Coro is portable even to
189     obsolete platforms.
190 root 1.202
191 root 1.201 3.4 Fri Jan 19 21:52:54 CET 2007
192 root 1.197 - remove t/09_timer.t, as it isn't really testing much
193     but was rather flaky in practise.
194 root 1.198 - async_pool coro would keep arguments and callback alive until
195     it was reused.
196 root 1.199 - cancellation of a coroutine could cause spurious idle calls
197     in cede_notself.
198 root 1.197
199 root 1.196 3.3 Sat Jan 6 03:45:00 CET 2007
200 root 1.187 - implement $coro->on_destroy.
201 root 1.188 - Coro::Event blocking semantics have been changed,
202     documented and - hopefully - improved.
203 root 1.184 - fix nice adding, not subtracting, from priority.
204 root 1.185 - fix ->prio and api_is_ready (patch by Mark Hinds).
205 root 1.190 - fixed an assert ("... == prev__cctx->idle_te")
206     that could errronously trigger.
207 root 1.192 - fix various large and small memleaks.
208 root 1.191 - use a (hopefully) more stable cancel implementation
209     that immediately frees the coroutine data.
210 root 1.194 - cede/cede_notself return a status now.
211 root 1.191 - added Coro::guard function.
212 root 1.193 - added a global coroutine pool for jobs (on my machine,
213     I can create and execute 48k simple coros/s with async,
214     and 128k coros with async_pool).
215 root 1.195 - Coro::AIO now uses the coroutine priority as io priority.
216 root 1.184
217 root 1.183 3.2 Fri Dec 22 05:07:09 CET 2006
218 root 1.179 - improve portability to slightly older perls.
219 root 1.180 - use cleaner coroutine destruction.
220 root 1.182 - simplify configuration for users.
221     - optionally (unrecommended) prefer perl functions over
222     their coro replacements.
223 root 1.179
224 root 1.178 3.11 Tue Dec 5 13:11:24 CET 2006
225     - fixed some bogus assert's, but as perl.h disables assert even
226     without NDEBUG (thank you very much), not too many people should
227     notice (that did include myself). Andreas König noticed, though :)
228     - do not save/restore PL_sortcxix on >= 5.9.x, it doesn't seem to have
229     it. Also noticed by Andreas König :)
230     - save/restore tainted status.
231     - verified to pass the testsuite on my 5.9.5.
232    
233 root 1.177 3.1 Mon Dec 4 23:03:40 CET 2006
234     - INCOMPATIBLE CHANGE: $/ is now per-coroutine (but slow).
235 root 1.175 - incompatible change: transfer flags are now per-state.
236 root 1.173 - give a better error message on deadlock.
237 root 1.175 - document Coro::nready.
238 root 1.174 - enhanced testsuite.
239 root 1.169
240 root 1.172 3.01 Sun Dec 3 23:47:42 CET 2006
241     - forgot to include Coro::Timer.
242    
243 root 1.171 3.0 Sun Dec 3 22:57:25 CET 2006
244 root 1.163 - the "FINALLY COMPLETELY STABLE" release (coming soon:
245     the "FAMOUS LAST WORDS" release).
246 root 1.166 - implement a new stack sharing algorithm, which uses a stack
247     pool (size currently hardcoded).
248 root 1.155 - make stack sharing mandatory (it no longer uses a heuristic).
249 root 1.157 - eval/die no longer cause weird problems under heavy use.
250 root 1.152 - Coro::Event could cause livelocks if it was used but
251 root 1.161 no Coro::Event watchers were used.
252 root 1.167 - Coro::Event now uses asynccheck as prepare does not
253     check for changed watchers.
254 root 1.170 - Coro::Event allows multiple waiting coros and will wake up one
255     per event.
256 root 1.152 - Coro::Event should be cleaner and more efficient now.
257 root 1.165 - new utility function Coro::unblock_sub.
258 root 1.164 - document the sad fact that Event is no longer reentrant.
259 root 1.163 - putting a coroutine into the ready queue twice could under
260     some circumstances lead to stack corruption.
261 root 1.161 - minor incompatibility: subclassing Coro::State is supported
262     directly now without going through a _coro_state member.
263 root 1.156 - state/coro switching is much faster now.
264 root 1.154 - very minor optimisations and code/documentation cleanup.
265 root 1.153 - avoid problems due to compiler inlining.
266 root 1.154 - removed timers from Coro::Timer -> use AnyEvent instead.
267     - replaced Coro::idle coroutine by (cleaner) idle handler.
268 root 1.156 - updated to newest libcoro.
269 root 1.159 - implement enhanced support for valgrind.
270 root 1.162 - implement is_ready and return value for ready.
271 root 1.168 - removed Coro::Cont, it was a misnomer (it's generators),
272     and it was somewhat annoying to get it right. Will come back
273     if somebody asks for it :)
274 root 1.163 - many ->wait methods and Coro::Event could return
275     spuriously without the event having happened.
276 root 1.146
277 root 1.145 2.5 Tue Nov 7 12:22:33 CET 2006
278 root 1.143 - made Coro::Util, Coro::Select, Coro::Handle and Coro::Socket
279     use AnyEvent, moved them to Coro/.
280 root 1.140 - added Coro::LWP which contains all the uglyness required to
281     make LWP non-blocking.
282     - should work with perl 5.9.x now (Andreas König made me do it).
283 root 1.141 - fixed another bug in Coro::Select when the timeout was undef.
284 root 1.136 - reuse PL_start_env for all coros, saves some memory per coroutine.
285     - manage PL_top_env differently, hopefully to avoid panic: top_env.
286 root 1.137 - timeout argument was not properly used in Coro::Socket.
287     - allow limited forms of subclassing in Coro::Handle/Coro::Socket.
288 root 1.138 - emulate undocumented(!) functionality of IO::Socket required
289     by LWP(!!).
290     - updated eg/lwp to work with newer lwp's.
291 root 1.140 - remove "FATAL: uncaught exception" prefix. Coroutines that die
292     kill the whole process, just as exceptions in the main "coroutine"
293     did already.
294 root 1.135
295 root 1.134 2.1 Wed Nov 1 23:01:13 CET 2006
296     - fix a long-standing bug in Coro::Select where select with
297     zero timeout would instead change the current default filehandle.
298 root 1.132 - use a simpler and hopefully more robust way to clone padlists
299     (uses less memory and a perl function instead of our own).
300     - coro can now create a stack guard area on many architectures.
301 root 1.134 - Coro::AIO properly reexports additional functions from IO::AIO.
302 root 1.132 - updated libcoro with a workaround for OS X,
303 root 1.134 pach and testing by Michael Schwern.
304 root 1.130
305 root 1.129 2.0 Tue Oct 24 05:47:17 CEST 2006
306 root 1.128 - support additional aio requests in Coro::AIO.
307    
308 root 1.129 1.9 (never properly released due to a glitch)
309    
310 root 1.127 1.8 Thu Feb 2 00:59:06 CET 2006
311 root 1.125 - applied suggested patch by SAMV to avoid problems during stupid
312     mark & sweep gc run.
313 root 1.126 - applied patch by Scott Walters for 5.9.3 compatibility.
314 root 1.125
315 root 1.124 1.7 Tue Dec 27 01:41:58 CET 2005
316 root 1.123 - added Coro::AIO, a thin wrapper around IO::AIO.
317 root 1.122 - improved Makefile.PL explanations.
318    
319 root 1.119 1.6 Mon Dec 12 21:30:05 CET 2005
320 root 1.117 - additionally save PM_curpm might fix as-of-yet
321 root 1.121 unseen problems with regex matches being attributed to the
322 root 1.117 wrong package.
323 root 1.118 - add t/10_bugs.t, which currently checks against imho broken
324     perls that use 0.26MB of stack space per Perl_magic_get
325 root 1.121 invocation (newer linuxes) as opposed to the 0.0002MB perl
326     normally uses.
327 root 1.120 - make stacksize configurable for the ultimate debian experience.
328 root 1.117
329 root 1.116 1.51 Mon Dec 12 18:48:36 CET 2005

331    
332 root 1.115 1.5 Tue Nov 29 13:32:44 CET 2005
333 root 1.114 - use Coro::Event inside Coro::Select to avoid spurious deadlocks.
334 root 1.115 - fix Coro::Select 'select'.
335     - strict'ify some modules.
336 root 1.112 - libcoro errornously restored the SIGUSR2 handler to SIGUSR1.
337 root 1.115 - use XSLoader in selected modules.
338     - remove some 5.6 compatibility cruft.
339 root 1.112
340 root 1.111 1.4 Tue Sep 6 00:11:05 CEST 2005
341     - libcoro did not take into account the trampoline on amd64,
342     when 'l'inux method was used.

348 root 1.108 - no code changes. module seems to work fine.
349 root 1.106 - improve Coro::State docs, remove reference to nonexisting
350     Coro::State::flush method.
351 root 1.107 - no longer autodetect windows, present it as an option instead.
352 root 1.106
353 root 1.105 1.2 Mon May 16 02:00:55 CEST 2005
354 root 1.100 - included libcoro.c earlier in State.xs, might improve portability.
355 root 1.101 - use a faster and possibly more stable Coro::Cont implementation.
356 root 1.102 - accept x86_64 in addition to amd64 for optimized linux-amd64 support.

364 root 1.97 - support [l]inux method on amd64.
365 root 1.109 - allow some context switches while compiling/eval'ing.
366 root 1.97
367 root 1.96 1.0 Tue Aug 10 03:47:27 CEST 2004
368 root 1.95 - Event 0.89 fixes the bug again.
369 root 1.96 - fix the remaining(??) memleak. I didn't free the cache-AV for
370     padlists, so one AV per created anon-sub leaked.
371 root 1.95
372 pcg 1.94 0.97 Fri May 14 15:23:32 CEST 2004
373     - remove stupid gcc extension that was an experiment only anyway.
374    
375 pcg 1.93 0.96 Thu May 13 18:09:29 CEST 2004
376 root 1.103 - tell people if they have yet another broken Event variant.
377 pcg 1.91 - made Coro to work _better_ with threads (it seems that, as long
378     as you use Coros in one thread only everything will work fine.
379     Looking at the perl source the problem might be missing locking
380     between Coro and some perl internal routines. That's not easily
381     fixable).
382 pcg 1.92 - (hopefully) got rid of the static xnext inside transfer.
383 pcg 1.91
384 pcg 1.90 0.95 Sun Feb 15 03:20:28 CET 2004
385 pcg 1.86 - removed Coro::State::flush, implemented a new and much
386     faster caching mechanism by attaching magic to the CV.
387 pcg 1.87 - a memleak with (real) closures remains.
388 pcg 1.88 - dramatically reduced size of stacks to 65536 (linux/x86), after
389     observing that even myhttpd never had more than a kilobyte
390     of stack in use (stack is still only physically allocated in
391     pagesize increments for systems suporting mmap).
392 pcg 1.89 - fix for a "cygwin-64" architecture added, proposed by Stefan Traby.
393 pcg 1.90 - fix for threaded perl.
394 pcg 1.86
395 pcg 1.85 0.9 Sun Nov 23 04:32:39 CET 2003
396 pcg 1.84 - fix a few very hard to track down but (of course) stupid
397     memory leaks.
398     - stringify version number to avoid locale problems :(.
399 pcg 1.85 - perl 5.9.0 does not have SvPADBUSY, reported by Scott Walters,
400     hopefully ignoring it "just works".
401 pcg 1.84
402 pcg 1.83 0.8 Wed Nov 5 19:38:40 CET 2003
403     - port to perl5.005_03, but only 5.8.x+ is supported!
404 pcg 1.82 - honor LocalAddr even without LocalPort in Coro::Socket.
405    
406 root 1.81 0.7 Tue May 27 03:12:38 CEST 2003
407     - the version jump indicates some level of testing, not gobs
408     of new features.
409 root 1.80 - uh... I found the prompt function in ExtUtils::MakeMaker.
410     Highly correct stuff, that is...
411 root 1.81 - fixed(?) a bug with die's in coroutines causing "panic: top_env".
412     the fix is not well understood by the author, so beware :(.
413 root 1.80
414 root 1.79 0.652 Thu May 8 02:54:46 CEST 2003
415 root 1.76 - Applied patch by Slaven Rezic to set default to "s" on FreeBSD,
416 root 1.78 cause version 4 doesn't have ucontext.
417 root 1.77 - Benjamin Reed reported that setjmp works fine on darwin,
418     so preselect it.
419 root 1.76
420 root 1.75 0.651 Sat Mar 29 15:00:23 CET 2003

425 root 1.72 - added a README.linux-glibc.
426     - new module Coro::Select.
427     - also save/restore PL_comppad, fixes segfaults with 5.8.1.
428     (I never claimed that I know what I am doing ;).
429 root 1.73 - set default to setjmp/longjmp on non-x86-linux.
430 root 1.72
431 root 1.71 0.6 Thu Nov 21 11:09:06 CET 2002
432     - made lazy context switching the default.
433     - fixed the bug where SemaphoreSet::guard
434     was the same as timed_guard and timed_guard was missing.
435     - fix a memleak in Coro::Timer.
436     - reclassified context sharing as not experimental.
437    
438 root 1.70 0.534 Sun Apr 14 03:05:12 CEST 2002
439 root 1.69 - fixed backspace => tab in header parsing (myhttpd).
440 root 1.70 - added eg/readline, for elmex.
441     - Coro::Event now calls ->start on first call instead of
442     ->again, which created wrong timeouts for the first ->next.
443     - fixed a bug where Coro::Socket returned a closed socket instead
444     of nothing on ECONNREFUSED and similar error conditions.
445 root 1.69
446 root 1.68 0.533 Mon Feb 18 18:49:40 CET 2002
447     - adapt to finally working Event-0.85.
448     - fixed buggy event initialization (trapped under windows, but how
449     could it possibly have worked anywhere?)
450    
451 root 1.67 0.532 Wed Jan 16 02:45:32 CET 2002
452 root 1.66 - removed the reference to pp_entersub, might work on
453     (some) win32 perls now (testsuite works under cygwin,
454     without Event, which freezes).
455 root 1.65
456 root 1.64 0.531 Mon Dec 10 22:18:44 CET 2001
457 root 1.63 - Fixed a bug in SemaphoreSet::timed_down.

460 root 1.60 - some tests for Event.
461 root 1.61 - slightly different internal architecture to get refcnt into the object
462     and not the reference. might fix a few bugs, certainly did introduce
463     new ones.
464     - Coro::Timer (independent of Event).
465 root 1.62 - new timed_wait functions for Coro::Signal, Semaphore, SemaphoreSet.
466 root 1.60
467 root 1.64 0.52 Tue Nov 6 21:36:18 CET 2001
468 root 1.58 - ported to cygwin (trivial).
469     patch by Gerrit P. Haase <gp@familiehaase.de>.
470     - small setjmp code fix by Sullivan.DanielJ@epamail.epa.gov.
471    
472 root 1.64 0.51 Thu Nov 1 20:39:01 CET 2001
473 root 1.54 - terminate/cancel now work properly (otherwise termination
474     could cause a "next coroutine is not and contains not..."
475     error.
476 root 1.55 - added Coro::Socket::shutdown.
477 root 1.56 - Coro::Event::loop no is the same as Event::loop.

479 root 1.54
480 root 1.64 0.5 Fri Sep 28 16:15:35 CEST 2001
481 root 1.53 - fixed "print" on a Coro::Handle. The print method worked.
482 root 1.50 - small tweaks (seem to reduce memory consumption a lot)
483     in various modules.
484     - splendid use of "no warnings" scattered throughout.
485 root 1.52 - added Coro::Handle::rbuf, fixed Coro::Handle::fh.
486 root 1.48
487 root 1.47 0.49 Sun Sep 16 02:42:45 CEST 2001
488 root 1.43 - changed some method calls to function calls for speed
489     inside Coro::Handle.
490 root 1.44 - make Coro::Handle use an array instead of a hash for
491     speed reasons.
492     - IRIX mystery solved: it's SGI's NT, after all: "standard, huh?".
493     sjlj and ucontext should now work.
494     - IRIX-specific port for libcoro.
495 root 1.45 - swapped order of accept results to match IO::Socket.
496 root 1.46 - changed getsock/peername to sock/peername to match IO::Socket.
497     - fixed a bug that caused segfault when returning to main task
498     under some circumstances.
499     - other bugfixes.

501 root 1.42 0.45 Sun Sep 2 02:54:01 CEST 2001
502 root 1.36 - new method Coro::Handle::timeout.

504     - Coro::Socket::accept now returns a Coro::Socket, not a Coro::Handle.
505     - Coro::Handle now supports fileno and FILENO.
506     - added eg/myhttpd, a web server.
507 root 1.37 - Coro::Socket now accepts numeric ports as well as "port(number)"
508     syntax.
509 root 1.38 - moved some scheduling primitives into xs code. more to come.
510 root 1.39 - new simple priority system.

515 root 1.31 - new method Coro::Handle::readline.

517     (see eg/lwp on how to make LWP non-blocking).
518 root 1.31 - renamed Coro::Socket::new_inet to new.
519 root 1.32 - added Coro::Util, some utility functions.
520 root 1.33 - die/eval now works better (still get annoying (but true ;)
521     "Callback called exit" messages).
522 root 1.34 - Coro::Handle now supports timeout, and Coro::Socket Timeout.

526 root 1.29 - do not use mmap if neither MAP_ANON nor MAP_ANONYMOUS is defined.
527 root 1.34 - very experimental stack sharing algorithm. not 100% safe but
528 root 1.28 should work well in practise ;)
529 root 1.30 - added Coro::RWLock.
530 root 1.31 - Coro::Specific now works.

538 root 1.23 - release candidate 3. A rather new internal structure :(
539 root 1.24 - the great renaming: Damian Conway gave me a suitable replacement
540     for yield.
541 root 1.23 - added Coro/libcoro, a portable coroutine implementation for C
542 root 1.22 (not even perl-dependent!!!), which can be used by Coro::State.
543 root 1.20 - renamed SAVE_DEFSV (on xs-level only) to avoid symbol clash in
544     perl-5.6.
545 root 1.16 - new function Coro::Event::idle.
546     - the idle process is now overriden
547     by default in Coro::Event.

553     non-blocking i/o.
554 root 1.25 - performance tuning.
555 root 1.16
556 root 1.15 0.08 Thu Jul 19 06:13:25 CEST 2001

568    
569 root 1.11 0.06 Tue Jul 17 04:23:24 CEST 2001
570     - ok, I found the showstopper - the same sub must not be
571 root 1.9 re-entered in two different coroutines, otherwise => crash. I
572     see no easy solution to this problem, except by walking the call
573     chaing and saving/restoring the cv's, which is what I do now.
574 root 1.11 - memory leaks still latent, especially at thread termination.
575     - Coro::Event now works (haha).
576 root 1.9
577 root 1.8 0.05 Sun Jul 15 17:32:20 CEST 2001

588 root 1.4
589 root 1.3 0.03 Fri Jul 13 14:51:52 CEST 2001
590 root 1.4 - transfer() now implemented in XS (beware).
591     - new module Coro::Cont for really faked continuations.
592     - big internal architecture changes: Coro::State is now
593 root 1.3 really low-level and can thus be used to implement other
594 root 1.4 interesting things, While "Coro::" implements a process-like
595     model. Still crude and subject to change.
