Revision history for Perl extension Coro. |
2 |
|
3 |
TODO: should explore PerlIO::via::CoroCede and PerlIO::via::CoroAIO. |
4 |
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 |
but very lacking in others (higher level ipc)). |
7 |
|
8 |
TODO: AnyEvent provide detetc hook |
9 |
TODO: Coro::AnyEvent |
10 |
- completely reworked the Coro manpage. |
11 |
- added Coro::AnyEvent, generic event loop integration. |
12 |
- implement cancel, ready and kill commands in Coro::Debug. |
13 |
- document find_coro in Coro::Debug. |
14 |
- incompatible change: rename has_stack to has_cctx. |
15 |
|
16 |
4.6 Sat Apr 26 10:05:14 CEST 2008 |
17 |
- INCOMPATIBLE CHANGE: sub/code attributes are no longer supported |
18 |
by the Coro module. It was a mistake to have it in the first place. |
19 |
- (experimental) support for activestate perl 5.10 (method "w"). |
20 |
- (experimental) support for strawberry perl (method "a"). |
21 |
- coro_sigelem_set did not return a value although it had to, |
22 |
actual impact unknown. |
23 |
|
24 |
4.51 Mon Apr 14 13:28:27 CEST 2008 |
25 |
- make it compile again on 5.8. |
26 |
|
27 |
4.50 Thu Apr 10 09:43:17 CEST 2008 |
28 |
- I did it twice! (see 4.49). |
29 |
|
30 |
4.49 Sun Apr 6 21:23:31 CEST 2008 |
31 |
- grr, instead of compiling the recent changes on 5.10 only they |
32 |
were compiled on 5.8 only. |
33 |
|
34 |
4.48 Sun Apr 6 20:36:46 CEST 2008 |
35 |
- allow coroutine switches during eval's under 5.10.x, as it seems |
36 |
the parser is a per-interpreter option now, so this is safe |
37 |
(this might fix the odd crashing bug). |
38 |
- drop support for 5.9.x versions: they are dead, jim. |
39 |
|
40 |
4.47 Sun Apr 6 00:37:52 CEST 2008 |
41 |
- force cctx allocation on API calls: we know we need to force one |
42 |
and gcc actually manages to confuse our heuristic nowadays, |
43 |
leading to crashes and worse. |
44 |
- document force_cctx. |
45 |
|
46 |
4.46 Fri Apr 4 22:05:43 CEST 2008 |
47 |
- upgrade libcoro, resulting in pthread-backend (which was only created |
48 |
to fulfill the rules of the programming languages shootout). |
49 |
|
50 |
4.45 Thu Mar 13 11:55:36 CET 2008 |
51 |
- fix a file leaking bug in eg/mhyttpd that would allow |
52 |
downloading of any file (reported by oesi). |
53 |
- fix deadlock bug in Coro::Channel (reported by Richard Hundt) |
54 |
(also add testcase). |
55 |
- support Broadcast option in Coro::Socket (patch by Richard Hundt, |
56 |
apparently having loads of fun with that). |
57 |
- implement $state->swap_defsv, ->swap_defav and document ->throw. |
58 |
|
59 |
4.4 Wed Feb 13 16:44:29 CET 2008 |
60 |
- only assume .cfi pseudo isns exist on GNU/Linux. |
61 |
- add get_timed method to Coro::Channels. |
62 |
- fixed Coro::Debug manpage. |
63 |
- perl 5.11 compatbility improvement based on patch by |
64 |
Andreas König. |
65 |
|
66 |
4.37 Sun Jan 20 11:25:23 CET 2008 |
67 |
- soften the check for an active parser for perl 5.10 (avoiding |
68 |
"Coro::State::transfer called while parsing" in many cases). |
69 |
|
70 |
4.36 Sun Jan 13 10:53:56 CET 2008 |
71 |
- reset diehook when terminating from an async_pool as to not |
72 |
trigger any __DIE__ handlers. |
73 |
|
74 |
4.35 Sun Jan 13 04:14:13 CET 2008 |
75 |
- "bt" debug command now displays any exceptions |
76 |
from longmess and also skips the innermost |
77 |
stackframes, giving more useufl output. |
78 |
- allow backtraces in coroutines blocked in Coro::EV, |
79 |
at a <1% speed hit. |
80 |
- handle localising of $SIG{__WARN__} and __DIE__ |
81 |
properly (with a proper amount of dirty hacking). |
82 |
|
83 |
4.34 Sat Dec 22 17:49:53 CET 2007 |
84 |
- upgrade to EV version 2.0 API. |
85 |
|
86 |
4.33 Mon Dec 17 08:36:12 CET 2007 |
87 |
- make Coro::AIO etc. loadable in the absence of EV. |
88 |
|
89 |
4.32 Mon Dec 17 07:46:02 CET 2007 |
90 |
- majorly improved Coro::Handle's performance with Coro::EV. |
91 |
- implemented the until now mythical Coro::BDB module. |
92 |
- specialcase EV in Coro::AIO and Coro::BDB for extra speed. |
93 |
|
94 |
4.31 Wed Dec 5 12:32:39 CET 2007 |
95 |
- remove warn statement form Coro::Util. |
96 |
|
97 |
4.3 Tue Dec 4 20:33:14 CET 2007 |
98 |
- calls to the idle function could cause stack corruption |
99 |
when the stack changed. |
100 |
- do no longer rely on the presence of EV::DNS if EV is used |
101 |
(because it is gone), but instead take avdantage of EV::ADNS |
102 |
if available. |
103 |
- add ($) prototypes to all functions in Coro::Storable. |
104 |
- use a conventional (safer) idle callback in Coro::EV. |
105 |
- do accept quickly in Coro::Debug to avoid endless loops. |
106 |
|
107 |
4.22 Fri Nov 30 16:04:04 CET 2007 |
108 |
- really use optimised versions for Event and EV in Coro::Util |
109 |
and Coro::Handle. |
110 |
|
111 |
4.21 Sun Nov 25 10:48:59 CET 2007 |
112 |
- fix a spurious memory read. |
113 |
- Coro::EV no longer keeps the eventloop "alive". |
114 |
|
115 |
4.2 Fri Nov 9 20:47:05 CET 2007 |
116 |
- enable/disable tracing from a new coroutine, not a pooled one. |
117 |
- fix a memleak in Coro::Event. |
118 |
- removed killall call from fork_eval. |
119 |
- made sure store_fd is already loaded so that fork_eval |
120 |
does not have to parse autoload in each subprocess. |
121 |
- only use assembly method if -O switch is in $Config{optimize}. |
122 |
- add (optional) Coro::EV module, so far the best event loop module |
123 |
directly supported by Coro. |
124 |
- if the event model is EV, use EV::DNS to resolve |
125 |
stuff in Coro::Util. |
126 |
- don't get confused by multiple event notifications in Coro::Handle. |
127 |
- initial support for EV (libevent interface). |
128 |
- require Event and EV using configure_requires, to force their existance. |
129 |
|
130 |
4.13 Wed Oct 24 07:26:45 CEST 2007 |
131 |
- add Coro::Storable::blocking_thaw. |
132 |
- use a vastly more complicated technique to localise |
133 |
$SIG{__WARN/DIE__} that also works on perls <= 5.8.8. |
134 |
- use a coroutine for the idle callback Coro::Event, |
135 |
instead of running Event in the current coroutine context. |
136 |
This also catches recursive invocations. |
137 |
- actually report fork errors in gethostbyname and inet_aton. |
138 |
|
139 |
4.11 Thu Oct 11 02:40:24 CEST 2007 |
140 |
- port to threaded perls. |
141 |
|
142 |
4.1 Thu Oct 11 02:38:16 CEST 2007 |
143 |
- incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now |
144 |
be local to each coro (see Coro::State). |
145 |
- incompatible change: for very deep reasons, cede and cede_notself |
146 |
cannot return anything, so nothing will be returned. |
147 |
- possibly bring back 5.10 compatibility (untested). |
148 |
- work around stupid (and wrong) warning on 5.10 :(. |
149 |
- overlay the saved state over the context stack. This saves |
150 |
a few hundred bytes per coroutine on average and also |
151 |
speeds up context switching a bit. |
152 |
- further tune default stack sizes. |
153 |
- (more) correctly calculate stack usage in coro_rss. |
154 |
- Coro::Storable::blocking_* did not properly lock |
155 |
resulting in races between coroutines. |
156 |
- added Coro::Storable::guard. |
157 |
- stopping to trace a coroutine could destroy the cctx of |
158 |
an unrelated coroutine. |
159 |
- explain the relationship between Perl and C coroutines in |
160 |
more detail in Coro::State. |
161 |
- Coro::Util::inet_aton did not short-circuit dotted quad forms, |
162 |
causing a fork per resolve. This also affected Coro::Socket. |
163 |
- switch to a separate stack in $coro->call/eval to avoid |
164 |
invalidating pointers. |
165 |
|
166 |
4.03 Sat Oct 6 21:24:00 CEST 2007 |
167 |
- added Coro::throw method. |
168 |
- minor code cleanups. |
169 |
|
170 |
4.02 Sat Oct 6 02:36:47 CEST 2007 |
171 |
- fix a very minor per-coroutine memleak (a single codereference). |
172 |
- fixed a bug where the currently in-use c context would be freed |
173 |
prematurely (can happen only when programs change the stacksize |
174 |
or use tracing). |
175 |
- tracing can no longer keep a coro alive after it terminated. |
176 |
- do static branch prediction in the common path for gcc. gives |
177 |
about 2-5% speed improvement here. |
178 |
|
179 |
4.01 Fri Oct 5 22:10:49 CEST 2007 |
180 |
- instead of recreating *a* standard output handle we simply |
181 |
use STDOUT, which is faster and hopefully more robust. |
182 |
|
183 |
4.0 Fri Oct 5 12:56:00 CEST 2007 |
184 |
- incompatibly changed Coro::Storable::freeze. |
185 |
- major new feature: added Coro::Debug, for interactive coroutine |
186 |
debugging, tracing and much more. |
187 |
- major bug fix: unbelievable, but true: $_, $/ and many other |
188 |
"saved" variables actually weren't being saved. This has been fixed, |
189 |
of course, while increasing performance while losing all the save |
190 |
flags. |
191 |
- save flags are gone, and all the api functions dealing with them. |
192 |
- added Coro::Semaphore::adjust. |
193 |
- added Coro::Util::fork_eval. |
194 |
- added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}. |
195 |
- added Coro::killall. |
196 |
- reduce initial stack sizes to allow for "micro-coroutines". |
197 |
- better async_pool resource management, moved parts of async_pool |
198 |
handling to XS (major speed improvement). |
199 |
- actually croak before modifying important data structures. |
200 |
- refuse to transfer while compiling. |
201 |
- possibly support eval EXPR better now. |
202 |
- enable assembly per default on linux+bsd x86+amd64. |
203 |
- all internal members were renamed _something for easier subclassing. |
204 |
- many minor tweaks. |
205 |
|
206 |
3.63 Wed May 16 14:10:06 CEST 2007 |
207 |
- implement handcoded assembly for x86/amd64 SVR ABI. |
208 |
|
209 |
3.62 Fri Apr 27 21:36:06 CEST 2007 |
210 |
- upgrade libcoro (which might set unwind info correctly). |
211 |
- change default on linux to setjmp/longjmp. |
212 |
|
213 |
3.61 Thu Apr 19 12:36:18 CEST 2007 |
214 |
- Coro::Storable caused an endless loop when thawing invalid |
215 |
pst's sometimes. |
216 |
- use a Semaphore in Coro::Storable, as Storable doesn't |
217 |
seem to be reentrant (although it is documented to |
218 |
be threadsafe...). |
219 |
- fix Coro::Signal to bring back the original unreliable |
220 |
but stateful semantics. |
221 |
- fixed a lot of typos in Coro.pm (patch submitted by David |
222 |
Steinbrunner, which applied flawlessly). |
223 |
|
224 |
3.6 Sat Apr 14 17:13:31 CEST 2007 |
225 |
- added some bugfixes to get eg/myhttpd working again. |
226 |
- added Coro::Storable for often-cede'ing freeze/thaw. |
227 |
- try to do a clean exit when a coroutine calls exit |
228 |
(EXPERIMENTAL). |
229 |
- got rid of indirect call through _coro_init. |
230 |
- updated the partly antique examples in eg/ to |
231 |
work again and be a bit less magic, too. |
232 |
- fixed Coro::Signal semantics to work as documented again. |
233 |
|
234 |
3.55 Sun Mar 25 01:20:47 CET 2007 |
235 |
- add SAVE_DEFFH to save the default filehandle and enable |
236 |
it by default. |
237 |
- finally move socket-operations from Coro::Socket to Coro::Handle |
238 |
to be able to unblock foreign sockets. |
239 |
- add Coro::State::save_also and guarded_save. |
240 |
- add count accessor to Coro::Semaphore. |
241 |
- add Coro::State::cctx_stacksize. |
242 |
- just for the fun of it, do not rely on implicit context, |
243 |
which can dramatically improve performance, but people |
244 |
using windows-process-emulation perls do not care much about |
245 |
performance. |
246 |
|
247 |
3.51 Sun Mar 4 14:18:04 CET 2007 |
248 |
- fixed a problem when you weakened references to Coro::State's |
249 |
(patch by Yuval Kogman). |
250 |
|
251 |
3.501 Wed Feb 28 12:44:07 CET 2007 |
252 |
- rename some global symbols as macosx from hell redefines |
253 |
them without asking. |
254 |
|
255 |
3.5 Tue Feb 13 20:22:53 CET 2007 |
256 |
- do AnyEvent model detection earlier, avoiding problems |
257 |
caused by first using AnyEvent and later Coro::Event. |
258 |
- implement and document Coro::Event event objects. |
259 |
- fix a potential problem in Coro::Event causing crashes. |
260 |
- initialise PL_comppad when creating a new coroutine, |
261 |
avoids crashes on early coro destruction. |
262 |
|
263 |
3.41 Mon Jan 22 19:19:49 CET 2007 |
264 |
- readline on Coro::Handle did not support undefined $/, |
265 |
nor did it deliver partial lines on EOF or error. |
266 |
- implement malloc fallback for stack allocation because |
267 |
stupid broken idiotic OSX has a stupid broken |
268 |
idiotic fits-the-whole-os mmap "implementation" and |
269 |
my dick feels longer if Coro is portable even to |
270 |
obsolete platforms. |
271 |
|
272 |
3.4 Fri Jan 19 21:52:54 CET 2007 |
273 |
- remove t/09_timer.t, as it isn't really testing much |
274 |
but was rather flaky in practise. |
275 |
- async_pool coro would keep arguments and callback alive until |
276 |
it was reused. |
277 |
- cancellation of a coroutine could cause spurious idle calls |
278 |
in cede_notself. |
279 |
|
280 |
3.3 Sat Jan 6 03:45:00 CET 2007 |
281 |
- implement $coro->on_destroy. |
282 |
- Coro::Event blocking semantics have been changed, |
283 |
documented and - hopefully - improved. |
284 |
- fix nice adding, not subtracting, from priority. |
285 |
- fix ->prio and api_is_ready (patch by Mark Hinds). |
286 |
- fixed an assert ("... == prev__cctx->idle_te") |
287 |
that could errronously trigger. |
288 |
- fix various large and small memleaks. |
289 |
- use a (hopefully) more stable cancel implementation |
290 |
that immediately frees the coroutine data. |
291 |
- cede/cede_notself return a status now. |
292 |
- added Coro::guard function. |
293 |
- added a global coroutine pool for jobs (on my machine, |
294 |
I can create and execute 48k simple coros/s with async, |
295 |
and 128k coros with async_pool). |
296 |
- Coro::AIO now uses the coroutine priority as io priority. |
297 |
|
298 |
3.2 Fri Dec 22 05:07:09 CET 2006 |
299 |
- improve portability to slightly older perls. |
300 |
- use cleaner coroutine destruction. |
301 |
- simplify configuration for users. |
302 |
- optionally (unrecommended) prefer perl functions over |
303 |
their coro replacements. |
304 |
|
305 |
3.11 Tue Dec 5 13:11:24 CET 2006 |
306 |
- fixed some bogus assert's, but as perl.h disables assert even |
307 |
without NDEBUG (thank you very much), not too many people should |
308 |
notice (that did include myself). Andreas König noticed, though :) |
309 |
- do not save/restore PL_sortcxix on >= 5.9.x, it doesn't seem to have |
310 |
it. Also noticed by Andreas König :) |
311 |
- save/restore tainted status. |
312 |
- verified to pass the testsuite on my 5.9.5. |
313 |
|
314 |
3.1 Mon Dec 4 23:03:40 CET 2006 |
315 |
- INCOMPATIBLE CHANGE: $/ is now per-coroutine (but slow). |
316 |
- incompatible change: transfer flags are now per-state. |
317 |
- give a better error message on deadlock. |
318 |
- document Coro::nready. |
319 |
- enhanced testsuite. |
320 |
|
321 |
3.01 Sun Dec 3 23:47:42 CET 2006 |
322 |
- forgot to include Coro::Timer. |
323 |
|
324 |
3.0 Sun Dec 3 22:57:25 CET 2006 |
325 |
- the "FINALLY COMPLETELY STABLE" release (coming soon: |
326 |
the "FAMOUS LAST WORDS" release). |
327 |
- implement a new stack sharing algorithm, which uses a stack |
328 |
pool (size currently hardcoded). |
329 |
- make stack sharing mandatory (it no longer uses a heuristic). |
330 |
- eval/die no longer cause weird problems under heavy use. |
331 |
- Coro::Event could cause livelocks if it was used but |
332 |
no Coro::Event watchers were used. |
333 |
- Coro::Event now uses asynccheck as prepare does not |
334 |
check for changed watchers. |
335 |
- Coro::Event allows multiple waiting coros and will wake up one |
336 |
per event. |
337 |
- Coro::Event should be cleaner and more efficient now. |
338 |
- new utility function Coro::unblock_sub. |
339 |
- document the sad fact that Event is no longer reentrant. |
340 |
- putting a coroutine into the ready queue twice could under |
341 |
some circumstances lead to stack corruption. |
342 |
- minor incompatibility: subclassing Coro::State is supported |
343 |
directly now without going through a _coro_state member. |
344 |
- state/coro switching is much faster now. |
345 |
- very minor optimisations and code/documentation cleanup. |
346 |
- avoid problems due to compiler inlining. |
347 |
- removed timers from Coro::Timer -> use AnyEvent instead. |
348 |
- replaced Coro::idle coroutine by (cleaner) idle handler. |
349 |
- updated to newest libcoro. |
350 |
- implement enhanced support for valgrind. |
351 |
- implement is_ready and return value for ready. |
352 |
- removed Coro::Cont, it was a misnomer (it's generators), |
353 |
and it was somewhat annoying to get it right. Will come back |
354 |
if somebody asks for it :) |
355 |
- many ->wait methods and Coro::Event could return |
356 |
spuriously without the event having happened. |
357 |
|
358 |
2.5 Tue Nov 7 12:22:33 CET 2006 |
359 |
- made Coro::Util, Coro::Select, Coro::Handle and Coro::Socket |
360 |
use AnyEvent, moved them to Coro/. |
361 |
- added Coro::LWP which contains all the uglyness required to |
362 |
make LWP non-blocking. |
363 |
- should work with perl 5.9.x now (Andreas König made me do it). |
364 |
- fixed another bug in Coro::Select when the timeout was undef. |
365 |
- reuse PL_start_env for all coros, saves some memory per coroutine. |
366 |
- manage PL_top_env differently, hopefully to avoid panic: top_env. |
367 |
- timeout argument was not properly used in Coro::Socket. |
368 |
- allow limited forms of subclassing in Coro::Handle/Coro::Socket. |
369 |
- emulate undocumented(!) functionality of IO::Socket required |
370 |
by LWP(!!). |
371 |
- updated eg/lwp to work with newer lwp's. |
372 |
- remove "FATAL: uncaught exception" prefix. Coroutines that die |
373 |
kill the whole process, just as exceptions in the main "coroutine" |
374 |
did already. |
375 |
|
376 |
2.1 Wed Nov 1 23:01:13 CET 2006 |
377 |
- fix a long-standing bug in Coro::Select where select with |
378 |
zero timeout would instead change the current default filehandle. |
379 |
- use a simpler and hopefully more robust way to clone padlists |
380 |
(uses less memory and a perl function instead of our own). |
381 |
- coro can now create a stack guard area on many architectures. |
382 |
- Coro::AIO properly reexports additional functions from IO::AIO. |
383 |
- updated libcoro with a workaround for OS X, |
384 |
pach and testing by Michael Schwern. |
385 |

390 |
|
391 |
1.8 Thu Feb 2 00:59:06 CET 2006 |
392 |
- applied suggested patch by SAMV to avoid problems during stupid |
393 |
mark & sweep gc run. |
394 |

399 |
|
400 |

401 |
- additionally save PM_curpm might fix as-of-yet |
402 |
unseen problems with regex matches being attributed to the |
403 |
wrong package. |
404 |
- add t/10_bugs.t, which currently checks against imho broken |
405 |
perls that use 0.26MB of stack space per Perl_magic_get |
406 |
invocation (newer linuxes) as opposed to the 0.0002MB perl |
407 |
normally uses. |
408 |
- make stacksize configurable for the ultimate debian experience. |
409 |
|
410 |
1.51 Mon Dec 12 18:48:36 CET 2005 |

414 |
- use Coro::Event inside Coro::Select to avoid spurious deadlocks. |
415 |
- fix Coro::Select 'select'. |
416 |
- strict'ify some modules. |
417 |
- libcoro errornously restored the SIGUSR2 handler to SIGUSR1. |
418 |
- use XSLoader in selected modules. |
419 |
- remove some 5.6 compatibility cruft. |
420 |
|
421 |
1.4 Tue Sep 6 00:11:05 CEST 2005 |
422 |
- libcoro did not take into account the trampoline on amd64, |
423 |
when 'l'inux method was used. |
424 |
|
425 |
1.31 Tue Aug 30 23:31:33 CEST 2005 |
426 |
- some portability fixes/workarounds. |
427 |
|
428 |
1.3 Sat Aug 20 03:08:56 CEST 2005 |
429 |
- no code changes. module seems to work fine. |
430 |
- improve Coro::State docs, remove reference to nonexisting |
431 |
Coro::State::flush method. |
432 |
- no longer autodetect windows, present it as an option instead. |
433 |
|
434 |
1.2 Mon May 16 02:00:55 CEST 2005 |
435 |
- included libcoro.c earlier in State.xs, might improve portability. |
436 |
- use a faster and possibly more stable Coro::Cont implementation. |
437 |
- accept x86_64 in addition to amd64 for optimized linux-amd64 support. |
438 |
- fix bugs Coro::SemaphoreSet that could cause locks never to be freed. |
439 |
- fix bugs in CoroAPI.h and document it in Coro::MakeMaker. |
440 |
|
441 |
1.11 Thu Mar 3 18:00:52 CET 2005 |
442 |

443 |
|
444 |
1.1 Tue Feb 22 20:51:16 CET 2005 |
445 |
- support [l]inux method on amd64. |
446 |
- allow some context switches while compiling/eval'ing. |
447 |
|
448 |
1.0 Tue Aug 10 03:47:27 CEST 2004 |
449 |
- Event 0.89 fixes the bug again. |
450 |
- fix the remaining(??) memleak. I didn't free the cache-AV for |
451 |
padlists, so one AV per created anon-sub leaked. |
452 |
|
453 |
0.97 Fri May 14 15:23:32 CEST 2004 |
454 |
- remove stupid gcc extension that was an experiment only anyway. |
455 |
|
456 |
0.96 Thu May 13 18:09:29 CEST 2004 |
457 |
- tell people if they have yet another broken Event variant. |
458 |
- made Coro to work _better_ with threads (it seems that, as long |
459 |
as you use Coros in one thread only everything will work fine. |
460 |
Looking at the perl source the problem might be missing locking |
461 |
between Coro and some perl internal routines. That's not easily |
462 |
fixable). |
463 |
- (hopefully) got rid of the static xnext inside transfer. |
464 |
|
465 |
0.95 Sun Feb 15 03:20:28 CET 2004 |
466 |
- removed Coro::State::flush, implemented a new and much |
467 |
faster caching mechanism by attaching magic to the CV. |
468 |
- a memleak with (real) closures remains. |
469 |
- dramatically reduced size of stacks to 65536 (linux/x86), after |
470 |
observing that even myhttpd never had more than a kilobyte |
471 |
of stack in use (stack is still only physically allocated in |
472 |
pagesize increments for systems suporting mmap). |
473 |
- fix for a "cygwin-64" architecture added, proposed by Stefan Traby. |
474 |
- fix for threaded perl. |
475 |
|
476 |
0.9 Sun Nov 23 04:32:39 CET 2003 |
477 |
- fix a few very hard to track down but (of course) stupid |
478 |
memory leaks. |
479 |
- stringify version number to avoid locale problems :(. |
480 |
- perl 5.9.0 does not have SvPADBUSY, reported by Scott Walters, |
481 |
hopefully ignoring it "just works". |
482 |
|
483 |
0.8 Wed Nov 5 19:38:40 CET 2003 |
484 |
- port to perl5.005_03, but only 5.8.x+ is supported! |
485 |
- honor LocalAddr even without LocalPort in Coro::Socket. |
486 |
|
487 |
0.7 Tue May 27 03:12:38 CEST 2003 |
488 |
- the version jump indicates some level of testing, not gobs |
489 |
of new features. |
490 |
- uh... I found the prompt function in ExtUtils::MakeMaker. |
491 |
Highly correct stuff, that is... |
492 |
- fixed(?) a bug with die's in coroutines causing "panic: top_env". |
493 |
the fix is not well understood by the author, so beware :(. |
494 |
|
495 |
0.652 Thu May 8 02:54:46 CEST 2003 |
496 |
- Applied patch by Slaven Rezic to set default to "s" on FreeBSD, |
497 |
cause version 4 doesn't have ucontext. |
498 |
- Benjamin Reed reported that setjmp works fine on darwin, |
499 |
so preselect it. |
500 |
|
501 |
0.651 Sat Mar 29 15:00:23 CET 2003 |
502 |
- fix a bug in Coro::Handle where some bytes could get lost |
503 |
on reading, reported by jason@nichego.net. |
504 |
|
505 |
0.65 Sun Mar 23 00:08:26 CET 2003 |
506 |
- added a README.linux-glibc. |
507 |
- new module Coro::Select. |
508 |
- also save/restore PL_comppad, fixes segfaults with 5.8.1. |
509 |
(I never claimed that I know what I am doing ;). |
510 |
- set default to setjmp/longjmp on non-x86-linux. |
511 |
|
512 |
0.6 Thu Nov 21 11:09:06 CET 2002 |
513 |
- made lazy context switching the default. |
514 |
- fixed the bug where SemaphoreSet::guard |
515 |
was the same as timed_guard and timed_guard was missing. |
516 |
- fix a memleak in Coro::Timer. |
517 |
- reclassified context sharing as not experimental. |
518 |
|
519 |
0.534 Sun Apr 14 03:05:12 CEST 2002 |
520 |
- fixed backspace => tab in header parsing (myhttpd). |
521 |
- added eg/readline, for elmex. |
522 |
- Coro::Event now calls ->start on first call instead of |
523 |
->again, which created wrong timeouts for the first ->next. |
524 |
- fixed a bug where Coro::Socket returned a closed socket instead |
525 |
of nothing on ECONNREFUSED and similar error conditions. |
526 |
|
527 |
0.533 Mon Feb 18 18:49:40 CET 2002 |
528 |
- adapt to finally working Event-0.85. |
529 |
- fixed buggy event initialization (trapped under windows, but how |
530 |
could it possibly have worked anywhere?) |
531 |
|
532 |
0.532 Wed Jan 16 02:45:32 CET 2002 |
533 |
- removed the reference to pp_entersub, might work on |
534 |
(some) win32 perls now (testsuite works under cygwin, |
535 |
without Event, which freezes). |
536 |
|
537 |
0.531 Mon Dec 10 22:18:44 CET 2001 |
538 |
- Fixed a bug in SemaphoreSet::timed_down. |
539 |
|
540 |
0.53 Tue Nov 27 21:11:13 CET 2001 |
541 |
- some tests for Event. |
542 |
- slightly different internal architecture to get refcnt into the object |
543 |
and not the reference. might fix a few bugs, certainly did introduce |
544 |
new ones. |
545 |
- Coro::Timer (independent of Event). |
546 |
- new timed_wait functions for Coro::Signal, Semaphore, SemaphoreSet. |
547 |
|
548 |
0.52 Tue Nov 6 21:36:18 CET 2001 |
549 |
- ported to cygwin (trivial). |
550 |
patch by Gerrit P. Haase <gp@familiehaase.de>. |
551 |
- small setjmp code fix by Sullivan.DanielJ@epamail.epa.gov. |
552 |
|
553 |
0.51 Thu Nov 1 20:39:01 CET 2001 |
554 |
- terminate/cancel now work properly (otherwise termination |
555 |
could cause a "next coroutine is not and contains not..." |
556 |
error. |
557 |
- added Coro::Socket::shutdown. |
558 |
- Coro::Event::loop no is the same as Event::loop. |
559 |
- implemented terminate with args + join. |
560 |
|
561 |
0.5 Fri Sep 28 16:15:35 CEST 2001 |
562 |
- fixed "print" on a Coro::Handle. The print method worked. |
563 |
- small tweaks (seem to reduce memory consumption a lot) |
564 |
in various modules. |
565 |
- splendid use of "no warnings" scattered throughout. |
566 |
- added Coro::Handle::rbuf, fixed Coro::Handle::fh. |
567 |
|
568 |
0.49 Sun Sep 16 02:42:45 CEST 2001 |
569 |
- changed some method calls to function calls for speed |
570 |
inside Coro::Handle. |
571 |
- make Coro::Handle use an array instead of a hash for |
572 |
speed reasons. |
573 |
- IRIX mystery solved: it's SGI's NT, after all: "standard, huh?". |
574 |
sjlj and ucontext should now work. |
575 |
- IRIX-specific port for libcoro. |
576 |
- swapped order of accept results to match IO::Socket. |
577 |
- changed getsock/peername to sock/peername to match IO::Socket. |
578 |
- fixed a bug that caused segfault when returning to main task |
579 |
under some circumstances. |
580 |
- other bugfixes. |
581 |
|
582 |
0.45 Sun Sep 2 02:54:01 CEST 2001 |
583 |
- new method Coro::Handle::timeout. |
584 |
- corrected speling of set...name to get...name in Coro::Socket. |
585 |
- Coro::Socket::accept now returns a Coro::Socket, not a Coro::Handle. |
586 |
- Coro::Handle now supports fileno and FILENO. |
587 |
- added eg/myhttpd, a web server. |
588 |
- Coro::Socket now accepts numeric ports as well as "port(number)" |
589 |
syntax. |
590 |
- moved some scheduling primitives into xs code. more to come. |
591 |
- new simple priority system. |
592 |
- implemented Coro::Event using XS, almost four times faster! |
593 |
- small memory corruption problem fixed (boy that was difficult). |
594 |
|
595 |
0.13 Wed Aug 8 16:53:07 CEST 2001 |
596 |
- new method Coro::Handle::readline. |
597 |
- added eg/lwp and Coro::Handle::autoflush, to make LWP work. |
598 |
(see eg/lwp on how to make LWP non-blocking). |
599 |
- renamed Coro::Socket::new_inet to new. |
600 |
- added Coro::Util, some utility functions. |
601 |
- die/eval now works better (still get annoying (but true ;) |
602 |
"Callback called exit" messages). |
603 |
- Coro::Handle now supports timeout, and Coro::Socket Timeout. |
604 |
- much better Coro::Socket support. |
605 |
|
606 |
0.12 Fri Jul 27 04:19:01 CEST 2001 |
607 |
- do not use mmap if neither MAP_ANON nor MAP_ANONYMOUS is defined. |
608 |
- very experimental stack sharing algorithm. not 100% safe but |
609 |
should work well in practise ;) |
610 |
- added Coro::RWLock. |
611 |
- Coro::Specific now works. |
612 |
|
613 |
0.11 Tue Jul 24 22:49:21 CEST 2001 |
614 |
- added specialized hack for newer and older linux versions (fast). |
615 |
- renamed Coro::Event::IO to Coro::Handle. |
616 |
- new module Coro::Socket. |
617 |
|
618 |
0.1 Tue Jul 24 01:47:53 CEST 2001 |
619 |
- release candidate 3. A rather new internal structure :( |
620 |
- the great renaming: Damian Conway gave me a suitable replacement |
621 |
for yield. |
622 |
- added Coro/libcoro, a portable coroutine implementation for C |
623 |
(not even perl-dependent!!!), which can be used by Coro::State. |
624 |
- renamed SAVE_DEFSV (on xs-level only) to avoid symbol clash in |
625 |
perl-5.6. |
626 |
- new function Coro::Event::idle. |
627 |
- the idle process is now overriden |
628 |
by default in Coro::Event. |
629 |
- Coro::Channel now enforces the size. |
630 |
- canceling events now works in all cases. |
631 |
- Coro state now include $_ and $@. |
632 |
- yet another bug workaround that I do not really understand :( |
633 |
- new module Coro::Event::IO (very undocumented) to do |
634 |
non-blocking i/o. |
635 |
- performance tuning. |
636 |
|
637 |
0.08 Thu Jul 19 06:13:25 CEST 2001 |
638 |
- release candidate 2 (new functionality). |
639 |
- add Coro::State::flush function. |
640 |
- transfer now supports a flags value (mostly for speed ATM). |
641 |
- might compile and work in the presence of threads now. |
642 |
- continuations have a saner syntax. |
643 |
- no more memleaks. |
644 |
|
645 |
0.07 Tue Jul 17 17:40:18 CEST 2001 |
646 |
- release candidate 1 ;) |
647 |
- slightly nicer code. |
648 |
- fixed a scheduling bug in Coro::Event. |
649 |
|
650 |
0.06 Tue Jul 17 04:23:24 CEST 2001 |
651 |
- ok, I found the showstopper - the same sub must not be |
652 |
re-entered in two different coroutines, otherwise => crash. I |
653 |
see no easy solution to this problem, except by walking the call |
654 |
chaing and saving/restoring the cv's, which is what I do now. |
655 |
- memory leaks still latent, especially at thread termination. |
656 |
- Coro::Event now works (haha). |
657 |
|
658 |
0.05 Sun Jul 15 17:32:20 CEST 2001 |
659 |
- fixed a few issues in Coro::Event. |
660 |
- I forgot to include Coro::Event in 0.04 :(:(:( |
661 |
|
662 |
0.04 Sun Jul 15 05:24:59 CEST 2001 |
663 |
- @_ is now properly localized. |
664 |
- Coro::State is now easier subclassable. |
665 |
- Coro::Cont now coroutine-aware. |
666 |
- Coro::Specific is a low-overhead module to create |
667 |
coroutine-specific vars. |
668 |
- Coro::Event provides a simple interface to Event. |
669 |
|
670 |
0.03 Fri Jul 13 14:51:52 CEST 2001 |
671 |
- transfer() now implemented in XS (beware). |
672 |
- new module Coro::Cont for really faked continuations. |
673 |
- big internal architecture changes: Coro::State is now |
674 |
really low-level and can thus be used to implement other |
675 |
interesting things, While "Coro::" implements a process-like |
676 |
model. Still crude and subject to change. |
677 |
- $_ and $@ are no longer being localized. |
678 |
|
679 |
0.02 Tue Jul 10 01:38:17 CEST 2001 |
680 |
- implemented "async" attribute. |
681 |
- $_ and $@ are now localized. |
682 |
- added Coro::Channel. |
683 |
- more testcases, still no docs. |
684 |
|
685 |
0.01 Tue Jul 3 02:18:41 CEST 2001 |
686 |
- original version; copied from Convert::Scalar. |
687 |
|
