- updated |

|
11 |
6.09 Sat Oct 6 23:25:02 CEST 2012 |
12 |
- Coro::EV I/O watchers were not interruptible by exceptions |
13 |
(Coro::State::throw) (testcase by sten). |
14 |
- ->throw now puts threads into the ready queue, as this seems to |
15 |
be expected by existing code, and code that doesn't cope with spurious |
16 |
wakeups needs fixing anyway. |
17 |
- use fd -1 in mmap. |
18 |
- cast I32 to int in error message printf. |
19 |
- warn about broken so-called "hardened" kernels. |
20 |
|
21 |
6.08 Fri Apr 13 12:05:47 CEST 2012 |
22 |
- be more aggressive about exiting like perl does - formerly, |
23 |
exiting from the non-main thread would not execute END blocks. |
24 |
|
25 |
6.07 Fri Nov 11 21:21:48 CET 2011 |
26 |
- work around a bug in PerlIO (setting $SIG{__WARN__} to a PVCV). |
27 |
- update ecb.h. |
28 |
|
29 |
6.06 Mon Aug 8 23:59:48 CEST 2011 |
30 |
- cygwin unfortunately patches the stack at runtime, so we use the pthreads |
31 |
backend, which is an order of magnitude slower. unfortunately, cygwins |
32 |
pthread implementation isn't very complete either, so allocate the stack |
33 |
twice just to be sure. |
34 |
(note: cygwin also enables mymalloc, which is NOT THREADSAFE ON WINDOWS, |
35 |
in its ithreaded perl - best recompile cygwin and use the 'w'indows |
36 |
backend for much better performance. also disable ithreads for |
37 |
even better performance...). |
38 |
|
39 |
6.05 Thu Aug 4 21:36:36 CEST 2011 |
40 |
- blush, condvar values would not be propagated from send to recv anymore |
41 |
(reported by Chip Salzenberg). |
42 |
- use exponential increase for the readline buffer length in |
43 |
Coro::Handle. also reduce initial allocation to 1020 from 4096 bytes. |
44 |
|
45 |
6.04 Wed Aug 3 17:15:45 CEST 2011 |
46 |
- use even more efficient and more compatible condvars for |
47 |
compatibility to AnyEvent 6.x :) |
48 |
- more inconsequential ecb.h updates. |
49 |
|
50 |
6.03 Wed Aug 3 11:41:30 CEST 2011 |
51 |
- change how Coro patches AnyEvent condvars for compatibility to |
52 |
AnyEvent 6.x. |
53 |
- update ecb.h, to no longer include <pthread.h> in case WinNT.h |
54 |
hasn't been included. |
55 |
|
56 |
6.02 Wed Jul 13 04:35:19 CEST 2011 |
57 |
- "improve portability to Gentoo" - gentoo manages to put perl variables |
58 |
in memory areas that are farther than 2gb apart, which the jit couldn't |
59 |
handle and barfed. now it's just a bit slower on gentoo and similar |
60 |
systems. |
61 |
|
62 |
6.01 Sun Jul 3 12:31:14 CEST 2011 |
63 |
- workarounds are good, but the test for whether pthreads are used |
64 |
was not good. thisone should be better. |
65 |
- check differently whether gcc generates cfi instructions itself. |
66 |
|
67 |
6.0 Wed Jun 29 19:43:35 CEST 2011 |
68 |
- INCOMPATIBLE CHANGE: unreferenced coro objects will now be |
69 |
destroyed and cleaned up automatically (e.g. async { schedule }). |
70 |
- implement a JIT compiler for part of the thread switch code, |
71 |
which gives a 50% speed improvement on threaded perls, and |
72 |
about 4% on non-thraeded perls (so threaded perls now finally |
73 |
reach about half the speed of non-threaded perls). |
74 |
- slightly modernise Coro::Intro, add section about rouse functions. |
75 |
- avoid DEFSV and ERRSV, giving another 10% improvement |
76 |
in thread switching. |
77 |
- Coro::State->is_destroyed is now called is_zombie. |
78 |
- implement a Coro->safe_cancel method that might fail, but |
79 |
cancels in a "safer" way if it succeeds. |
80 |
- add preliminary support for DEBUGGING perls. |
81 |
- get rid of two hash-accesses when initialising a new Coro - this |
82 |
speeds up coro creation by almost a factor of two. |
83 |
- croak when a coro that is being cancelled tries to block |
84 |
(e.g. while executing a guard block), instead of crashing or |
85 |
deadlocking. |
86 |
- use a more robust and also faster method to identify Coro::State |
87 |
objects - speeds up everything a bit. |
88 |
- implement Coro->cancel in XS for a 20% speed improvement, and to |
89 |
be able to implement mutual cancellation. |
90 |
- speed up context switches by a percent or two by more efficiently |
91 |
allocating context stack entries. |
92 |
- implement Coro->join and Coro->on_destroy in XS for a speedup and |
93 |
a reduction in memory use. |
94 |
- cancelling a coro while it itself is cancelling another coro is |
95 |
now supported and working, instead of triggering an assertion. |
96 |
- be a bit more crash-resistant when calling (buggy) on_destroy |
97 |
callbacks (best effort). |
98 |
- move on_destroy into the slf_frame, to allow extension slf |
99 |
functions to have destructors. |
100 |
- get rid if coro refcounting - simply crash in other interpreter |
101 |
threads by nulling the pointers on clone. |
102 |
- simplify warn/die hook handling when loading Coro - the convoluted |
103 |
logic seems to be no longer neccessary. |
104 |
- use libecb instead of our own home-grown gcc hacks. |
105 |
- document alternatives to Coro::LWP. Please use them :) |
106 |
- work around another mindless idiotic NEEDLESS bug in openbsd/mirbsds |
107 |
sigaltstack. Really. wine suffers from it, erlang suffers from it, |
108 |
and it's known since at least 2006. |
109 |
|
110 |
5.372 Wed Feb 23 06:14:30 CET 2011 |
111 |
- apparently mingw doesn't provide a working gettimeofday, try to |
112 |
work around that by relying on Time::HiRes (indirectly brought to |
113 |
my attention by Max Maischein). |
114 |
- fix some portability issues when Time::HiRes was used. |
115 |
|
116 |
5.371 Mon Feb 21 14:36:08 CET 2011 |
117 |
- backport to windows process emulation code again. |
118 |
|
119 |
5.37 Sat Feb 19 07:49:44 CET 2011 |
120 |
- add a big "Coro thread life cycle" section to "man Coro". |
121 |
- try a tentative workaround against the breakage that 5.13 has |
122 |
introduced without depreciation period. sigh. |
123 |
- no longer use Time::HiRes if gettimeofday is available, which |
124 |
saves quite a lot of memory. |
125 |
|
126 |
5.36 Sun Feb 13 05:33:41 CET 2011 |
127 |
- automatically load Coro::Channel, Coro::RWLock, Coro::Semaphore, |
128 |
Coro::SemaphoreSet, Coro::Signal and Coro::Specific on first "new" |
129 |
method call. |
130 |
- undocument Coro::Timer::sleep and obsolete whole module. |
131 |
- optimise Coro::Timer::timeout memory and cpu usage. |
132 |
- slightly updated Coro::Intro for recent changes. |
133 |
- do not initialise PL_dirty anymore. |
134 |
|
135 |
5.25 Thu Nov 11 01:08:39 CET 2010 |
136 |
- try a different approach on netbsd - netbsd 5 finally has marginally |
137 |
working pthreads, but still broken ucontext/sigaltstack. |
138 |
- openbsd 4.8 finally got their act together, Coro works out of the box |
139 |
with asm, setjmp and pthreads (no change, just informational). |
140 |
|
141 |
5.24 Sat Oct 23 11:27:12 CEST 2010 |
142 |
- port to the EV 4.0 API. |
143 |
- work around bugs in mingw32, making strawberry perl work |
144 |
out of the box. |
145 |
- correctly modify Coro::AIO function prototypes |
146 |
so that they reflect the "no optional parameters" rule. |
147 |
- "ported" libcoro to C++. |
148 |
|
149 |
5.23 Mon May 17 18:50:42 CEST 2010 |
150 |
- be more resistant to ordering changes when initialising |
151 |
Coro::AnyEvent, Coro::EV and Coro::Event (reported by Matthias |
152 |
Waldorf). |
153 |
- document that perl 5.12 deliberately removed support for cloning. |
154 |
|
155 |
5.22 Wed Apr 14 03:55:35 CEST 2010 |
156 |
- correctly return udnef on errors in Coro::Handle::read/write |
157 |
(testcase by Marc Mims). |
158 |
- convert Coro::Util into a "perl compatibility wrapper" - the functions |
159 |
are less useful now, but are drop-in replacements for existing |
160 |
functions, listing better alternatives in the documentation. This also |
161 |
fixes a bug in Coro::LWP which naively substituted Socket::inet_aton |
162 |
with Coro::Util::inet_aton. |
163 |
- do not override $Coro::idle unconditionally in Coro.pm, as other |
164 |
modules could have provided their own idle coro already |
165 |
(for exmaple, Coro::AnyEvent). |
166 |
- fix Coro::Util::gethost* functions. |
167 |
- Coro::Timer corretcly exports it's symbols (reported by Hideki Yamamura). |
168 |
|
169 |
5.21 Wed Dec 16 07:19:51 CET 2009 |
170 |
- automatically load Coro::AnyEvent when AnyEvent and Coro are used |
171 |
together. |
172 |
- add some examples on how to combine other event loops with Coro in |
173 |
Coro::AnyEvent, and how to run it (and not to block). Seems to be |
174 |
the most common source of confusion. |
175 |
- try to catch people naively blocking in an event callback. |
176 |
- work around the perl filehandle bug issue in conjunction with |
177 |
older common::sense (as indirectly pointed out by ZSystem). |
178 |
- clarify the "not from signal handlers" section. |
179 |
|
180 |
5.2 Sun Oct 4 14:54:24 CEST 2009 |
181 |
- Coro::Storable destroyed the prototypes of the functions it wrapped. |
182 |
- export rouse_cb and rouse_wait by default now. |
183 |
- fix various prototype mismatches in Coro::AnyEvent and Coro::Handle. |
184 |
- new method $state->swap_sv. |
185 |
- added section on "windows process emulation" to the manpage, |
186 |
after a not-so-fruitful (nor-friendly) "discussion" with chip |
187 |
salzenberg (discussion implies arguments, but his only arguments |
188 |
were ad-hominems, one wonders why he started it in the first |
189 |
place). I hope this explains it well enough for him to understand, |
190 |
and maybe well enough for others to understand. |
191 |
- use common::sense everywhere now. |
192 |
- idle callbacks are no longer supported, use idle coros instead. |
193 |
- print a thread listing when a deadlock is detected. |
194 |
|
195 |
5.17 Sat Aug 22 23:09:31 CEST 2009 |
196 |
- work around a bug in the perl debugger causing crashes |
197 |
when running under the debugger by marking _pool_handler as nodebug. |
198 |
- speed up Coro::async considerably. |
199 |
- try some hacks to get netbsd to work "more often" - their broken |
200 |
setjmp/longjmp, ucontext *and* phtreads are really hard on Coro. |
201 |
- convert Coro to AE 5.0 API. |
202 |
|
203 |
5.162 Tue Jul 28 04:04:03 CEST 2009 |
204 |
- perl 5.8.2 is now minimum requirement. |
205 |
- skip t/19_handle.t on broken windows perls. |
206 |
|
207 |
5.161 Wed Jul 22 04:47:38 CEST 2009 |
208 |
- Coro::AnyEvent::poll could have a different prototype when EV was |
209 |
used as backend (analyzed by Tatsuhiko Miyagawa). |
210 |
- Coro::AnyEvent errornously initialised the event loop when loaded, |
211 |
not on demand. |
212 |
- try to workaround rare */t/01_unblock.t failures. |
213 |
|
214 |
5.16 Tue Jul 21 01:44:37 CEST 2009 |
215 |
- Coro::AnyEvent failed to hook into the event loop |
216 |
when no threads had been readied between detecting |
217 |
the event loop and actually running it. |
218 |
- considerably speed up Coro::Select by taking avdantage |
219 |
of AnyEvent > 4.8 and some other optimisations. |
220 |
- implement paragraph readline mode in Coro::Handle |
221 |
(based on patches by Zsbán Ambrus). |
222 |
- replace WSAEINPROGRESS by WSAEWOULDBLOCK (reported |
223 |
and analyzed by Yasuhiro MATSUMOTO). |
224 |
- clarified libcoro license and copyright. |
225 |
- someone stole my EXTRA_META!!! |
226 |
- implement Coro::Select::patch_pp_sselect and it's brother, |
227 |
for hardcode select overriding. |
228 |
|
229 |
5.151 Mon Jul 6 05:41:57 CEST 2009 |
230 |
- backport to windows process emulation code again (patch by |
231 |
Yasuhiro MATSUMOTO). |
232 |
- slightly update Coro::MakeMaker. |
233 |
|
234 |
5.15 Tue Jun 30 10:28:06 CEST 2009 |
235 |
- deprecate Coro::Socket, document how to get ipv6 support via |
236 |
AnyEvent::Socket instead. |
237 |
- implement signal->wait ($cb) interface, similar to semaphores. |
238 |
- work around SvOK not supporting getmagic, so we have to getmagic |
239 |
to test for undef :/ (reported by Matthias Waldorf). |
240 |
- load Coro::AnyEvent in all modules using AnyEvent. |
241 |
- work around perl corrupting our internal data structures, |
242 |
reported by Tokuhiro Matsuno. |
243 |
- enable per-coroutine real and cpu time gathering |
244 |
(Coro::State::enable_times). |
245 |
|
246 |
5.14 Wed Jun 24 01:37:48 CEST 2009 |
247 |
- provide explicit functions to "cede" to the event loop in Coro::AnyEvent, |
248 |
as this seems to have been a difficult concept (poll, sleep, idle, |
249 |
idle_upto). |
250 |
- add Coro::AnyEvent::readable/writable functions. |
251 |
- clarify Coro::EV/Event/AnyEvent manpages. |
252 |
- free per-thread global scalars in the thread calling ->cancel, to |
253 |
avoid crashes when $_, $@ etc., are magical but some of those |
254 |
had already been freed. |
255 |
- "unexperimentalise" the callback interface for Coro::Semaphore. |
256 |
- speed up ready queue management/context switching by using a linked |
257 |
list instead of an array (~5-10%). |
258 |
- implement "watch" command in Coro::Debug shells. |
259 |
- for fun, implement time-slicing as an example in the manpage. |
260 |
- if AnyEvent detects EV or Event, but we don't have Coro::EV or |
261 |
Coro::Event, use the normal AnyEvent handling instead of dieing |
262 |
(the same is true for Coro::Handle). |
263 |
- properly document Coro::EV::timed_io_once. |
264 |
- avoid unneccessary ->cancel calls in Coro::Handle. |
265 |
- maybe make it work on mingw32 with win32 backend |
266 |
(based on patch by Yasuhiro Matsumoto). |
267 |
|
268 |
5.132 Fri May 29 09:00:39 CEST 2009 |
269 |
- do not keep a reference to the argument itself in |
270 |
Coro::Semaphore::guard, as it could change later. |
271 |
- support SO_RCVBUF/SO_SNDBUF nonstandard Coro::Socket options, |
272 |
should support a prepare callback. |
273 |
|
274 |
5.131 Mon Mar 16 23:20:37 CET 2009 |
275 |
- implement and document Coro->suspend, Coro->resume. |
276 |
- fix Coro::Select implementation to not (often) close |
277 |
the passed file descriptors (testcase provided by pippijn). |
278 |
|
279 |
5.13 Mon Dec 15 21:51:42 CET 2008 |
280 |
- EXPERIMENTAL: implement dynamic winds (on_enter/on_leave). |
281 |
- don't set diehook to C<undef> but instead to NULL, to avoid |
282 |
spurious warnings. |
283 |
- fix a lot of bugs in Coro::SemaphoreSet. |
284 |
- Coro::SemaphoreSet will less often create a semaphore needlessly. |
285 |
- add Coro::SemaphoreSet::count and wait methods. |
286 |
- take advantage of the new Guard module. |
287 |
- deprecate Coro::guard. |
288 |
- try to fix the dreaded 01_unblock tests once more. I hate it when |
289 |
testsuites need more fixing than the code they are supposed to test. |
290 |
- croak in more cases when a required callback isn't resolvable. |
291 |
- fix some minor issues in Coro::State->call/eval. |
292 |
- use current coroutine context instead of a temporary one |
293 |
when temporarily switching to another coroutine. |
294 |
- do not call C-level on_destroy handlers during global destruction, |
295 |
to avoid needless segfaults. |
296 |
|
297 |
5.12 Sun Dec 7 13:30:38 CET 2008 |
298 |
- add default config for MirOS, which seems to be a bug-to-bug |
299 |
compatible fork of openbsd ("world domination by releasing |
300 |
openbsd cvs before the openbsd folks do it" or so :). |
301 |
- free_padlist did destroy the names pad, not good, but didn't |
302 |
seem to bother perl - this could fix issues such as eval "" |
303 |
inside a function called from multiple coroutines. |
304 |
- use a different method to detect destruction time. |
305 |
- be more careful when freeing padlists just before global |
306 |
destruction. |
307 |
- fixed and expanded the call/cc example. |
308 |
- renamed _terminate to _coro_run. |
309 |
- new method Coro::Channel->shutdown. |
310 |
- try pthreads on openbsd <4.4 (broken sigaltstack, will |
311 |
pthreads fare better?). |
312 |
- be less picky about destroying "a" running coroutine. |
313 |
|
314 |
5.11 Tue Nov 25 21:49:05 CET 2008 |
315 |
- DEBUGGING in 5.10.0 is a mess: it constantly flags perfectly |
316 |
working code with failed assertions, introducing more bugs than |
317 |
it fixes, requiring elaborate workarounds :( |
318 |
|
319 |
5.1 Mon Nov 24 08:54:59 CET 2008 |
320 |
- wrote a small introductory tutorial - Coro::Intro. |
321 |
- convert Coro::Timer, Coro::Select and Coro::Util to rouse API. |
322 |
- Coro::Select did errornously dup the file descriptors |
323 |
and didn't work with all AnyEvent backends. |
324 |
- Coro::Select wasn't imported correctly form Coro::LWP, causing blocking |
325 |
LWP data transfers. |
326 |
- disassociate c contexts from coro objects - this is agruably more |
327 |
correct, but mostly allows sharing of cctxs between coro and state |
328 |
objects, for added memory savings and speed increases. |
329 |
- bumped $Coro::POOL_RSS up to 32kb by default. |
330 |
- no longer set the optype to OP_CUSTOM, as B::* understandably |
331 |
doesn't like this very much (and we *are* a type of entersub). |
332 |
- implement state cloning, just to prove that call/cc can be done. |
333 |
- automatically load Coro::AnyEvent in Coro::Handle. |
334 |
- wrap ->cancel calls in eval inside Coro::Handle as EV watchers |
335 |
do not have this method (and don't need it either). |
336 |
- speed up generic anyevent methods in Coro::Handle by using rouse |
337 |
callbacks. |
338 |
- allow coroutines in $Coro::IDLE, speeding up Coro::AnyEvent and |
339 |
others. It also makes the debugger happier, as you can trace |
340 |
through the idle threads now. |
341 |
- add comppad_name* and hints ($^H, %^H) to per-thread variables. |
342 |
- eg/event was pretty broken. |
343 |
- better 5.8.6 compatibility. |
344 |
|
345 |
5.0 Thu Nov 20 10:35:05 CET 2008 |
346 |
- NEW ARCHITECTURE: use the latest 4.x version if you experience |
347 |
stability issues. |
348 |
- bump API version to 7 - all dependents must be recompiled. |
349 |
- removed timed_* functions - they were not being used anyways |
350 |
and should be replaced by a more generic mechanism - |
351 |
and were annoying to support anyways :) |
352 |
- removed SemaphoreSet's waiter method - use sem method instead. |
353 |
- Coro::Semaphore->adjust didn't correctly wake up enough waiters. |
354 |
- async_pool did free a scalar value twice |
355 |
("Attempt to unreference..."). |
356 |
- fix a longstanding bug where calling terminate on a coro that |
357 |
was waiting for a semaphore that was just becoming available |
358 |
would cause a deadlock (semaphore would get into a state where |
359 |
it was available but waiters were still blocked). |
360 |
- calling throw on a coroutine that is waiting for a semaphore will |
361 |
no longer make it acquire the semaphore (and thus leak a count). |
362 |
- perl's process emulation is now not even theoretically supported |
363 |
anymore. |
364 |
- new functions Coro::rouse_cb and Coro::rouse_wait for easier |
365 |
conversion of callback-style to blocking-style. |
366 |
- new methods $coro->schedule_to and ->cede_to, to specifically |
367 |
schedule or cede to a specific coroutine. |
368 |
- new function Coro::Semaphore::wait. |
369 |
- use named constants in Coro::Channel (Richard Hundt). |
370 |
- directly patch the entersub opcode calling SLF functions (cede, |
371 |
transfer and so on). this does speed up context switching, but |
372 |
more importanly, it frees us from the hardcoded behaviour of |
373 |
entersub, so we might actually be able to return something from |
374 |
those functions and atcually create new ones. |
375 |
- take advantage of __builtin_frame_address on gcc. |
376 |
- expose THX in coroapi (not sure whether this was a wise decision, |
377 |
as "threaded" perls are running at half speed anyways). |
378 |
- implement execute_slf (schedule-like-function) interface that makes |
379 |
it possible to implement schedule-like-functions in XS. |
380 |
- use new SLF interface to massively speed up Coro::EV by roughly a |
381 |
factor of two. |
382 |
- used new SLF interface to massively speed up Coro::Semaphore by a |
383 |
factor of three. |
384 |
- used new SLF interface to speed up Coro::AIO by roughly a factor of |
385 |
four and reduce its memory usage considerably. |
386 |
- implement Coro::SemaphoreSet purely in terms of Coro::Semaphore, |
387 |
for a nice speedup and vastly more correct behaviour. Also implement |
388 |
a new method "sem" to get at the underlying semaphore object. |
389 |
- implement Coro::Channel in terms of Coro::Semaphore, for a moderate |
390 |
(in comparison) 20-40% speedup. |
391 |
- used new SLF interface to reimplement Coro::Signal gaining |
392 |
some unknown (because I was too lazy), but certain, speedup, and also |
393 |
making signals reliable for the first time. |
394 |
- used new SLF interface and other optimisations to speed up async_pool |
395 |
by a factor of two. It also doesn't rely on perl's exception mechanism |
396 |
to exit anymore. The overhead for terminating an async_pool, coro over |
397 |
a normal async is now very small. |
398 |
- sped up coroutine creation/destruction by 40%. |
399 |
- forgot to include Coro/libcoro/README in the dist for all these years. |
400 |
- work around a freebsd pthreads bug (manual testcancel is required as |
401 |
pthread_cond_wait isn't a cancellation point on freebsd). |
402 |
- use new rouse functions to speed up and simplify Coro::BDB. |
403 |
- make "prefer perl native functions" work with threaded perls. |
404 |
- condense Coro::Debug ps output, hint at v and w flags. |
405 |
- (libcoro) lots of minor cleanups and portability improvements. |
406 |
|
407 |
4.914 Wed Nov 19 12:54:18 CET 2008 |
408 |
- fix a disastrous bug in the readline optimisation |
409 |
introduced in 4.801. |
410 |
|
411 |
4.913 Sat Nov 15 07:58:28 CET 2008 |
412 |
- async_pool did free a scalar value twice |
413 |
("Attempt to unreference..."). |
414 |
|
415 |
4.912 Thu Nov 13 18:31:23 CET 2008 |
416 |
- minor cleanups. |
417 |
- use much larger stacks on linux and perl < 5.8.8. |
418 |
- Coro::Debug::new_unix_server did not unlink the socket |
419 |
when destroyed. |
420 |
|
421 |
4.911 Tue Nov 11 04:26:17 CET 2008 |
422 |
- "port" to threaded perls. |
423 |
|
424 |
4.91 Mon Nov 10 05:36:38 CET 2008 |
425 |
- the ->throw exception object no longer leaks. |
426 |
- creating a new cctx leaked a scopestack entry (memleak). |
427 |
- new coroutines didn't get created with a zero flags field |
428 |
(unknown impact). |
429 |
- calling ->throw on a not-yet-started coroutine should now work |
430 |
instead of being ignored. |
431 |
- ->throw is now supported on Coro::State objects. |
432 |
- clean up cctx creation code a bit. |
433 |
- entersub is actually a UNOP, not a LOGOP (not a bugfix). |
434 |
|
435 |
4.9 Sat Nov 8 17:45:27 CET 2008 |
436 |
- (libcoro) did not preserve rbp with CORO_ASM (we are getting there). |
437 |
- (libcoro) no longer leak threads in the experimental pthread backend, |
438 |
also speed it up considerably. |
439 |
- (libcoro) do not rely on makecontext passing void *'s unscathed. |
440 |
- fix compiletime dependencies on libcoro in the Makefile. |
441 |
- cctx_count wasn't always updated properly. |
442 |
- Coro::State::cctx_stacksize wasn't applied correctly. |
443 |
- new function Coro::State::cctx_max_idle. |
444 |
- the default max number of idle C contexts is now 4. |
445 |
- (libcoro) try harder to get _setjmp/_longjmp. |
446 |
- (libcoro) cleanup and extend the libcoro API to officially |
447 |
allow the creation of empty source contexts. |
448 |
- very experimental workaround for the totally broken netbsd platform. |
449 |
- tried to hack around openbsd bugs. |
450 |
|
451 |
4.804 Wed Nov 5 16:36:00 CET 2008 |
452 |
- Coro::Debug::new_unix_server would not create a non-blocking listening |
453 |
socket, sometimes causing freezes. |
454 |
- (libcoro) fix misaligned stack points for setjmp and assembly |
455 |
methods, which can cause crashes on x86/x86_64 with a sufficiently |
456 |
aggressive compiler. |
457 |
- new function: Coro::Debug::new_tcp_server. |
458 |
- move ->throw into the Coro class because it only works on coro objects. |
459 |
|
460 |
4.803 Mon Nov 3 17:16:12 CET 2008 |
461 |
- (libcoro) use a global asm statement to become independent of gcc |
462 |
otpimisations for CORO_ASM (thanks to pippijn for the idea). |
463 |
- try to workaround yet another broken bsd, this time dragonfly. |
464 |
|
465 |
4.802 Thu Oct 30 10:56:12 CET 2008 |
466 |
- support -fno-omit-frame-pointer on x86 with the assembly method. |
467 |
- tune 01_unblock.t tests a bit. |
468 |
|
469 |
4.801 Wed Oct 22 18:33:37 CEST 2008 |
470 |
- improve readline speed for very long "lines". |
471 |
- backport to 5.8.8. |
472 |
|
473 |
4.8 Thu Oct 2 13:34:40 CEST 2008 |
474 |
- new function Coro::AIO::aio_wait. |
475 |
- Coro.:AIO and Coro::BDB now "use Coro::AnyEvent". |
476 |
- greatly speed up and reduce memory usage of Coro::AIO requests. |
477 |
- implement some other µ-optimisations. |
478 |
|
479 |
4.749 Mon Sep 29 14:40:12 CEST 2008 |
480 |
- port to slow and broken pseudo-threaded perls. (courtesy pippijn). |
481 |
|
482 |
4.748 Sat Sep 27 14:03:19 CEST 2008 |
483 |
- implement, but do not document, PerlIO::cede(granularity). |
484 |
- Coro::Storable forgot to wrap Storable::pstore. |
485 |
- work around the multitude of leaks and memory corruption |
486 |
bugs in PerlIO::via by using our own C-level perliol. As a side |
487 |
effect, Coro::Storable is now much, much, much faster. |
488 |
|
489 |
4.747 Tue Sep 23 01:59:41 CEST 2008 |
490 |
- fix a per-cv memleak (one empty array was leaked per |
491 |
code reference). |
492 |
- avoid a crash in coro->call|rss when the coroutine was already |
493 |
destroyed (most noticably when using Coro::Debug::ps :) |
494 |
- also protect *Storable::FILE. |
495 |
- push up default storable granularity to 20ms. |
496 |
|
497 |
4.746 Sun Sep 21 03:22:20 CEST 2008 |
498 |
- be more insistent on locking Storable against reentrancy |
499 |
in Coro::Storable. |
500 |
- move swap_def?v and throw to Coro::State, as documented. |
501 |
|
502 |
4.745 Thu Jul 24 00:14:38 CEST 2008 |
503 |
- remove debugging code related to MgPV_nolen_const, also try to |
504 |
make it compile with perl 5.8.6 (yes, apple apparently loves |
505 |
outdated software). Reported by John S. |
506 |
|
507 |
4.744 Tue Jul 8 22:06:35 CEST 2008 |
508 |
- correctly provide default DIE/WARN handlers as documented. |
509 |
- also overwrite PL_vtbl_sigelem.svt_clear, even though current |
510 |
implementations inside perl work fine for us. |
511 |
|
512 |
4.743 Mon Jun 16 00:21:57 CEST 2008 |
513 |
- when using Coro::EV without running EV::loop it could |
514 |
result in busy-waiting for events, this has been fixed. |
515 |
- reduce codesize and improve performance by using EV_DEFAULT_UC. |
516 |
|
517 |
4.742 Sat May 31 14:10:21 CEST 2008 |
518 |
- implement a workaround for (some) perl <5.8.8 versions. |
519 |
- require EV 3.3+. |
520 |
|
521 |
4.741 Fri May 30 23:33:09 CEST 2008 |
522 |
- tell netbsd how utterly broken their imitation of an OS is |
523 |
and refuse to build by default if pthreads are in use. |
524 |
- switch to "s" method on all bsd's by default, as their ucontext |
525 |
stuff seems just too broken. |
526 |
- fix a bug in Coro::Select. |
527 |
|
528 |
4.74 Thu May 29 20:05:31 CEST 2008 |
529 |
- do not test Coro::LWP for lack of dependencies. |
530 |
- do not test Coro::Select for lack of working perls. |
531 |
|
532 |
4.73 Thu May 29 2008 |
533 |
- fix a bug in Coro::EV which would cause it to block despite |
534 |
there being runnable coroutines. |
535 |
- sprinkle "no warnings" freely over everything, also suppress |
536 |
warnings for some other modules. |
537 |
- fix typo in WSAEWOULDBLOCK. |
538 |
|
539 |
4.72 Sun May 25 05:14:36 CEST 2008 |
540 |
- tweak META.yaml a bit, unfortunately, there is no documented way |
541 |
to have optional dependencies with CPAN. doh :( |
542 |
- avoid running some tests on windows because they would fail due to |
543 |
perl bug (broken fork, broken pipes...). |
544 |
- work around perl on windows bugs where perl returns undocumented |
545 |
error codes for sysread, syswrite etc. by taking advantage |
546 |
of AnyEvent's workaround for that problem. |
547 |
- use AnyEvent::Util::fh_nonblocking in Coro::Handle to work around |
548 |
a common perl implementation bug on windows. |
549 |
- use unix domain sockets in testsuite to work around |
550 |
common perl implementation bugs on widows (they are emulated by |
551 |
tcp sockets on windows. ugh.) |
552 |
|
553 |
4.71 Sat May 24 20:01:27 CEST 2008 |
554 |
- fix a bug in Coro::AnyEvent ("Usage: Coro::AnyEvent::_schedule()"). |
555 |
- take advantage of async name resolution of AnyEvent::Util. |
556 |
- work around brutal inet_aton override in Coro::LWP. |
557 |
- take advantage of the readyhook in Coro::EV, for smoother |
558 |
scheduling. |
559 |
|
560 |
4.7 Sun May 11 00:32:19 CEST 2008 |
561 |
- completely reworked the Coro manpage. |
562 |
- added Coro::AnyEvent, generic event loop integration. |
563 |
- implement cancel, ready and kill commands in Coro::Debug. |
564 |
- document find_coro in Coro::Debug. |
565 |
- incompatible change: rename has_stack to has_cctx. |
566 |
- Coro::AIO and Coro::BDB no longer force event model detection, |
567 |
use AnyEvent::AIO and AnyEvent::BDB. |
568 |
|
569 |
4.6 Sat Apr 26 10:05:14 CEST 2008 |
570 |
- INCOMPATIBLE CHANGE: sub/code attributes are no longer supported |
571 |
by the Coro module. It was a mistake to have it in the first place. |
572 |
- (experimental) support for activestate perl 5.10 (method "w"). |
573 |
- (experimental) support for strawberry perl (method "a"). |
574 |
- coro_sigelem_set did not return a value although it had to, |
575 |
actual impact unknown. |
576 |
|
577 |
4.51 Mon Apr 14 13:28:27 CEST 2008 |
578 |
- make it compile again on 5.8. |
579 |
|
580 |
4.50 Thu Apr 10 09:43:17 CEST 2008 |
581 |
- I did it twice! (see 4.49). |
582 |
|
583 |
4.49 Sun Apr 6 21:23:31 CEST 2008 |
584 |
- grr, instead of compiling the recent changes on 5.10 only they |
585 |
were compiled on 5.8 only. |
586 |
|
587 |
4.48 Sun Apr 6 20:36:46 CEST 2008 |
588 |
- allow coroutine switches during eval's under 5.10.x, as it seems |
589 |
the parser is a per-interpreter option now, so this is safe |
590 |
(this might fix the odd crashing bug). |
591 |
- drop support for 5.9.x versions: they are dead, jim. |
592 |
|
593 |
4.47 Sun Apr 6 00:37:52 CEST 2008 |
594 |
- force cctx allocation on API calls: we know we need to force one |
595 |
and gcc actually manages to confuse our heuristic nowadays, |
596 |
leading to crashes and worse. |
597 |
- document force_cctx. |
598 |
|
599 |
4.46 Fri Apr 4 22:05:43 CEST 2008 |
600 |
- upgrade libcoro, resulting in pthread-backend (which was only created |
601 |
to fulfill the rules of the programming languages shootout). |
602 |
|
603 |
4.45 Thu Mar 13 11:55:36 CET 2008 |
604 |
- fix a file leaking bug in eg/mhyttpd that would allow |
605 |
downloading of any file (reported by oesi). |
606 |
- fix deadlock bug in Coro::Channel (reported by Richard Hundt) |
607 |
(also add testcase). |
608 |
- support Broadcast option in Coro::Socket (patch by Richard Hundt, |
609 |
apparently having loads of fun with that). |
610 |
- implement $state->swap_defsv, ->swap_defav and document ->throw. |
611 |
|
612 |
4.4 Wed Feb 13 16:44:29 CET 2008 |
613 |
- only assume .cfi pseudo isns exist on GNU/Linux. |
614 |
- add get_timed method to Coro::Channels. |
615 |
- fixed Coro::Debug manpage. |
616 |
- perl 5.11 compatbility improvement based on patch by |
617 |
Andreas König. |
618 |
|
619 |
4.37 Sun Jan 20 11:25:23 CET 2008 |
620 |
- soften the check for an active parser for perl 5.10 (avoiding |
621 |
"Coro::State::transfer called while parsing" in many cases). |
622 |
|
623 |
4.36 Sun Jan 13 10:53:56 CET 2008 |
624 |
- reset diehook when terminating from an async_pool as to not |
625 |
trigger any __DIE__ handlers. |
626 |
|
627 |
4.35 Sun Jan 13 04:14:13 CET 2008 |
628 |
- "bt" debug command now displays any exceptions |
629 |
from longmess and also skips the innermost |
630 |
stackframes, giving more useufl output. |
631 |
- allow backtraces in coroutines blocked in Coro::EV, |
632 |
at a <1% speed hit. |
633 |
- handle localising of $SIG{__WARN__} and __DIE__ |
634 |
properly (with a proper amount of dirty hacking). |
635 |
|
636 |
4.34 Sat Dec 22 17:49:53 CET 2007 |
637 |
- upgrade to EV version 2.0 API. |
638 |
|
639 |
4.33 Mon Dec 17 08:36:12 CET 2007 |
640 |
- make Coro::AIO etc. loadable in the absence of EV. |
641 |
|
642 |
4.32 Mon Dec 17 07:46:02 CET 2007 |
643 |
- majorly improved Coro::Handle's performance with Coro::EV. |
644 |
- implemented the until now mythical Coro::BDB module. |
645 |
- specialcase EV in Coro::AIO and Coro::BDB for extra speed. |
646 |
|
647 |
4.31 Wed Dec 5 12:32:39 CET 2007 |
648 |
- remove warn statement form Coro::Util. |
649 |
|
650 |
4.3 Tue Dec 4 20:33:14 CET 2007 |
651 |
- calls to the idle function could cause stack corruption |
652 |
when the stack changed. |
653 |
- do no longer rely on the presence of EV::DNS if EV is used |
654 |
(because it is gone), but instead take avdantage of EV::ADNS |
655 |
if available. |
656 |
- add ($) prototypes to all functions in Coro::Storable. |
657 |
- use a conventional (safer) idle callback in Coro::EV. |
658 |
- do accept quickly in Coro::Debug to avoid endless loops. |
659 |
|
660 |
4.22 Fri Nov 30 16:04:04 CET 2007 |
661 |
- really use optimised versions for Event and EV in Coro::Util |
662 |
and Coro::Handle. |
663 |
|
664 |
4.21 Sun Nov 25 10:48:59 CET 2007 |
665 |
- fix a spurious memory read. |
666 |
- Coro::EV no longer keeps the eventloop "alive". |
667 |
|
668 |
4.2 Fri Nov 9 20:47:05 CET 2007 |
669 |
- enable/disable tracing from a new coroutine, not a pooled one. |
670 |
- fix a memleak in Coro::Event. |
671 |
- removed killall call from fork_eval. |
672 |
- made sure store_fd is already loaded so that fork_eval |
673 |
does not have to parse autoload in each subprocess. |
674 |
- only use assembly method if -O switch is in $Config{optimize}. |
675 |
- add (optional) Coro::EV module, so far the best event loop module |
676 |
directly supported by Coro. |
677 |
- if the event model is EV, use EV::DNS to resolve |
678 |
stuff in Coro::Util. |
679 |
- don't get confused by multiple event notifications in Coro::Handle. |
680 |
- initial support for EV (libevent interface). |
681 |
- require Event and EV using configure_requires, to force their existance. |
682 |
|
683 |
4.13 Wed Oct 24 07:26:45 CEST 2007 |
684 |
- add Coro::Storable::blocking_thaw. |
685 |
- use a vastly more complicated technique to localise |
686 |
$SIG{__WARN/DIE__} that also works on perls <= 5.8.8. |
687 |
- use a coroutine for the idle callback Coro::Event, |
688 |
instead of running Event in the current coroutine context. |
689 |
This also catches recursive invocations. |
690 |
- actually report fork errors in gethostbyname and inet_aton. |
691 |
|
692 |
4.11 Thu Oct 11 02:40:24 CEST 2007 |
693 |
- port to threaded perls. |
694 |
|
695 |
4.1 Thu Oct 11 02:38:16 CEST 2007 |
696 |
- incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now |
697 |
be local to each coro (see Coro::State). |
698 |
- incompatible change: for very deep reasons, cede and cede_notself |
699 |
cannot return anything, so nothing will be returned. |
700 |
- possibly bring back 5.10 compatibility (untested). |
701 |
- work around stupid (and wrong) warning on 5.10 :(. |
702 |
- overlay the saved state over the context stack. This saves |
703 |
a few hundred bytes per coroutine on average and also |
704 |
speeds up context switching a bit. |
705 |
- further tune default stack sizes. |
706 |
- (more) correctly calculate stack usage in coro_rss. |
707 |
- Coro::Storable::blocking_* did not properly lock |
708 |
resulting in races between coroutines. |
709 |
- added Coro::Storable::guard. |
710 |
- stopping to trace a coroutine could destroy the cctx of |
711 |
an unrelated coroutine. |
712 |
- explain the relationship between Perl and C coroutines in |
713 |
more detail in Coro::State. |
714 |
- Coro::Util::inet_aton did not short-circuit dotted quad forms, |
715 |
causing a fork per resolve. This also affected Coro::Socket. |
716 |
- switch to a separate stack in $coro->call/eval to avoid |
717 |
invalidating pointers. |
718 |
|
719 |
4.03 Sat Oct 6 21:24:00 CEST 2007 |
720 |
- added Coro::throw method. |
721 |
- minor code cleanups. |
722 |
|
723 |
4.02 Sat Oct 6 02:36:47 CEST 2007 |
724 |
- fix a very minor per-coroutine memleak (a single codereference). |
725 |
- fixed a bug where the currently in-use c context would be freed |
726 |
prematurely (can happen only when programs change the stacksize |
727 |
or use tracing). |
728 |
- tracing can no longer keep a coro alive after it terminated. |
729 |
- do static branch prediction in the common path for gcc. gives |
730 |
about 2-5% speed improvement here. |
731 |
|
732 |
4.01 Fri Oct 5 22:10:49 CEST 2007 |
733 |
- instead of recreating *a* standard output handle we simply |
734 |
use STDOUT, which is faster and hopefully more robust. |
735 |
|
736 |
4.0 Fri Oct 5 12:56:00 CEST 2007 |
737 |
- incompatibly changed Coro::Storable::freeze. |
738 |
- major new feature: added Coro::Debug, for interactive coroutine |
739 |
debugging, tracing and much more. |
740 |
- major bug fix: unbelievable, but true: $_, $/ and many other |
741 |
"saved" variables actually weren't being saved. This has been fixed, |
742 |
of course, while increasing performance while losing all the save |
743 |
flags. |
744 |
- save flags are gone, and all the api functions dealing with them. |
745 |
- added Coro::Semaphore::adjust. |
746 |
- added Coro::Util::fork_eval. |
747 |
- added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}. |
748 |
- added Coro::killall. |
749 |
- reduce initial stack sizes to allow for "micro-coroutines". |
750 |
- better async_pool resource management, moved parts of async_pool |
751 |
handling to XS (major speed improvement). |
752 |
- actually croak before modifying important data structures. |
753 |
- refuse to transfer while compiling. |
754 |
- possibly support eval EXPR better now. |
755 |
- enable assembly per default on linux+bsd x86+amd64. |
756 |
- all internal members were renamed _something for easier subclassing. |
757 |
- many minor tweaks. |
758 |
|
759 |
3.63 Wed May 16 14:10:06 CEST 2007 |
760 |
- implement handcoded assembly for x86/amd64 SVR ABI. |
761 |
|
762 |
3.62 Fri Apr 27 21:36:06 CEST 2007 |
763 |
- upgrade libcoro (which might set unwind info correctly). |
764 |
- change default on linux to setjmp/longjmp. |
765 |
|
766 |
3.61 Thu Apr 19 12:36:18 CEST 2007 |
767 |
- Coro::Storable caused an endless loop when thawing invalid |
768 |
pst's sometimes. |
769 |
- use a Semaphore in Coro::Storable, as Storable doesn't |
770 |
seem to be reentrant (although it is documented to |
771 |
be threadsafe...). |
772 |
- fix Coro::Signal to bring back the original unreliable |
773 |
but stateful semantics. |
774 |
- fixed a lot of typos in Coro.pm (patch submitted by David |
775 |
Steinbrunner, which applied flawlessly). |
776 |
|
777 |
3.6 Sat Apr 14 17:13:31 CEST 2007 |
778 |
- added some bugfixes to get eg/myhttpd working again. |
779 |
- added Coro::Storable for often-cede'ing freeze/thaw. |
780 |
- try to do a clean exit when a coroutine calls exit |
781 |
(EXPERIMENTAL). |
782 |
- got rid of indirect call through _coro_init. |
783 |
- updated the partly antique examples in eg/ to |
784 |
work again and be a bit less magic, too. |
785 |
- fixed Coro::Signal semantics to work as documented again. |
786 |
|
787 |
3.55 Sun Mar 25 01:20:47 CET 2007 |
788 |
- add SAVE_DEFFH to save the default filehandle and enable |
789 |
it by default. |
790 |
- finally move socket-operations from Coro::Socket to Coro::Handle |
791 |
to be able to unblock foreign sockets. |
792 |
- add Coro::State::save_also and guarded_save. |
793 |
- add count accessor to Coro::Semaphore. |
794 |
- add Coro::State::cctx_stacksize. |
795 |
- just for the fun of it, do not rely on implicit context, |
796 |
which can dramatically improve performance, but people |
797 |
using windows-process-emulation perls do not care much about |
798 |
performance. |
799 |
|
800 |
3.51 Sun Mar 4 14:18:04 CET 2007 |
801 |
- fixed a problem when you weakened references to Coro::State's |
802 |
(patch by Yuval Kogman). |
803 |
|
804 |
3.501 Wed Feb 28 12:44:07 CET 2007 |
805 |
- rename some global symbols as macosx from hell redefines |
806 |
them without asking. |
807 |
|
808 |
3.5 Tue Feb 13 20:22:53 CET 2007 |
809 |
- do AnyEvent model detection earlier, avoiding problems |
810 |
caused by first using AnyEvent and later Coro::Event. |
811 |
- implement and document Coro::Event event objects. |
812 |
- fix a potential problem in Coro::Event causing crashes. |
813 |
- initialise PL_comppad when creating a new coroutine, |
814 |
avoids crashes on early coro destruction. |
815 |
|
816 |
3.41 Mon Jan 22 19:19:49 CET 2007 |
817 |
- readline on Coro::Handle did not support undefined $/, |
818 |
nor did it deliver partial lines on EOF or error. |
819 |
- implement malloc fallback for stack allocation because |
820 |
stupid broken idiotic OSX has a stupid broken |
821 |
idiotic fits-the-whole-os mmap "implementation" and |
822 |
my dick feels longer if Coro is portable even to |
823 |
obsolete platforms. |
824 |
|
825 |
3.4 Fri Jan 19 21:52:54 CET 2007 |
826 |
- remove t/09_timer.t, as it isn't really testing much |
827 |
but was rather flaky in practise. |
828 |
- async_pool coro would keep arguments and callback alive until |
829 |
it was reused. |
830 |
- cancellation of a coroutine could cause spurious idle calls |
831 |
in cede_notself. |
832 |
|
833 |
3.3 Sat Jan 6 03:45:00 CET 2007 |
834 |
- implement $coro->on_destroy. |
835 |
- Coro::Event blocking semantics have been changed, |
836 |
documented and - hopefully - improved. |
837 |
- fix nice adding, not subtracting, from priority. |
838 |
- fix ->prio and api_is_ready (patch by Mark Hinds). |
839 |
- fixed an assert ("... == prev__cctx->idle_te") |
840 |
that could errronously trigger. |
841 |
- fix various large and small memleaks. |
842 |
- use a (hopefully) more stable cancel implementation |
843 |
that immediately frees the coroutine data. |
844 |
- cede/cede_notself return a status now. |
845 |
- added Coro::guard function. |
846 |
- added a global coroutine pool for jobs (on my machine, |
847 |
I can create and execute 48k simple coros/s with async, |
848 |
and 128k coros with async_pool). |
849 |
- Coro::AIO now uses the coroutine priority as io priority. |
850 |
|
851 |
3.2 Fri Dec 22 05:07:09 CET 2006 |
852 |
- improve portability to slightly older perls. |
853 |
- use cleaner coroutine destruction. |
854 |
- simplify configuration for users. |
855 |
- optionally (unrecommended) prefer perl functions over |
856 |
their coro replacements. |
857 |
|
858 |
3.11 Tue Dec 5 13:11:24 CET 2006 |
859 |
- fixed some bogus assert's, but as perl.h disables assert even |
860 |
without NDEBUG (thank you very much), not too many people should |
861 |
notice (that did include myself). Andreas König noticed, though :) |
862 |
- do not save/restore PL_sortcxix on >= 5.9.x, it doesn't seem to have |
863 |
it. Also noticed by Andreas König :) |
864 |
- save/restore tainted status. |
865 |
- verified to pass the testsuite on my 5.9.5. |
866 |
|
867 |
3.1 Mon Dec 4 23:03:40 CET 2006 |
868 |
- INCOMPATIBLE CHANGE: $/ is now per-coroutine (but slow). |
869 |
- incompatible change: transfer flags are now per-state. |
870 |
- give a better error message on deadlock. |
871 |
- document Coro::nready. |
872 |
- enhanced testsuite. |
873 |
|
874 |
3.01 Sun Dec 3 23:47:42 CET 2006 |
875 |
- forgot to include Coro::Timer. |
876 |
|
877 |
3.0 Sun Dec 3 22:57:25 CET 2006 |
878 |
- the "FINALLY COMPLETELY STABLE" release (coming soon: |
879 |
the "FAMOUS LAST WORDS" release). |
880 |
- implement a new stack sharing algorithm, which uses a stack |
881 |
pool (size currently hardcoded). |
882 |
- make stack sharing mandatory (it no longer uses a heuristic). |
883 |
- eval/die no longer cause weird problems under heavy use. |
884 |
- Coro::Event could cause livelocks if it was used but |
885 |
no Coro::Event watchers were used. |
886 |
- Coro::Event now uses asynccheck as prepare does not |
887 |
check for changed watchers. |
888 |
- Coro::Event allows multiple waiting coros and will wake up one |
889 |
per event. |
890 |
- Coro::Event should be cleaner and more efficient now. |
891 |
- new utility function Coro::unblock_sub. |
892 |
- document the sad fact that Event is no longer reentrant. |
893 |
- putting a coroutine into the ready queue twice could under |
894 |
some circumstances lead to stack corruption. |
895 |
- minor incompatibility: subclassing Coro::State is supported |
896 |
directly now without going through a _coro_state member. |
897 |
- state/coro switching is much faster now. |
898 |
- very minor optimisations and code/documentation cleanup. |
899 |
- avoid problems due to compiler inlining. |
900 |
- removed timers from Coro::Timer -> use AnyEvent instead. |
901 |
- replaced Coro::idle coroutine by (cleaner) idle handler. |
902 |
- updated to newest libcoro. |
903 |
- implement enhanced support for valgrind. |
904 |
- implement is_ready and return value for ready. |
905 |
- removed Coro::Cont, it was a misnomer (it's generators), |
906 |
and it was somewhat annoying to get it right. Will come back |
907 |
if somebody asks for it :) |
908 |
- many ->wait methods and Coro::Event could return |
909 |
spuriously without the event having happened. |
910 |
|
911 |
2.5 Tue Nov 7 12:22:33 CET 2006 |
912 |
- made Coro::Util, Coro::Select, Coro::Handle and Coro::Socket |
913 |
use AnyEvent, moved them to Coro/. |
914 |
- added Coro::LWP which contains all the uglyness required to |
915 |
make LWP non-blocking. |
916 |
- should work with perl 5.9.x now (Andreas König made me do it). |
917 |
- fixed another bug in Coro::Select when the timeout was undef. |
918 |
- reuse PL_start_env for all coros, saves some memory per coroutine. |
919 |
- manage PL_top_env differently, hopefully to avoid panic: top_env. |
920 |
- timeout argument was not properly used in Coro::Socket. |
921 |
- allow limited forms of subclassing in Coro::Handle/Coro::Socket. |
922 |
- emulate undocumented(!) functionality of IO::Socket required |
923 |
by LWP(!!). |
924 |
- updated eg/lwp to work with newer lwp's. |
925 |
- remove "FATAL: uncaught exception" prefix. Coroutines that die |
926 |
kill the whole process, just as exceptions in the main "coroutine" |
927 |
did already. |
928 |
|
929 |
2.1 Wed Nov 1 23:01:13 CET 2006 |
930 |
- fix a long-standing bug in Coro::Select where select with |
931 |
zero timeout would instead change the current default filehandle. |
932 |
- use a simpler and hopefully more robust way to clone padlists |
933 |
(uses less memory and a perl function instead of our own). |
934 |
- coro can now create a stack guard area on many architectures. |
935 |
- Coro::AIO properly reexports additional functions from IO::AIO. |
936 |
- updated libcoro with a workaround for OS X, |
937 |
pach and testing by Michael Schwern. |
938 |
|
939 |
2.0 Tue Oct 24 05:47:17 CEST 2006 |
940 |
- support additional aio requests in Coro::AIO. |
941 |
|
942 |
1.9 (never properly released due to a glitch) |
943 |
|
944 |
1.8 Thu Feb 2 00:59:06 CET 2006 |
945 |
- applied suggested patch by SAMV to avoid problems during stupid |
946 |
mark & sweep gc run. |
947 |
- applied patch by Scott Walters for 5.9.3 compatibility. |
948 |
|
949 |
1.7 Tue Dec 27 01:41:58 CET 2005 |
950 |
- added Coro::AIO, a thin wrapper around IO::AIO. |
951 |
- improved Makefile.PL explanations. |
952 |
|
953 |
1.6 Mon Dec 12 21:30:05 CET 2005 |
954 |
- additionally save PM_curpm might fix as-of-yet |
955 |
unseen problems with regex matches being attributed to the |
956 |
wrong package. |
957 |
- add t/10_bugs.t, which currently checks against imho broken |
958 |
perls that use 0.26MB of stack space per Perl_magic_get |
959 |
invocation (newer linuxes) as opposed to the 0.0002MB perl |
960 |
normally uses. |
961 |
- make stacksize configurable for the ultimate debian experience. |
962 |
|
963 |
1.51 Mon Dec 12 18:48:36 CET 2005 |
964 |
- remove debugging warn() accidentally left in Coro::Select. |
965 |
|
966 |
1.5 Tue Nov 29 13:32:44 CET 2005 |
967 |
- use Coro::Event inside Coro::Select to avoid spurious deadlocks. |
968 |
- fix Coro::Select 'select'. |
969 |
- strict'ify some modules. |
970 |
- libcoro errornously restored the SIGUSR2 handler to SIGUSR1. |
971 |
- use XSLoader in selected modules. |
972 |
- remove some 5.6 compatibility cruft. |
973 |
|
974 |
1.4 Tue Sep 6 00:11:05 CEST 2005 |
975 |
- libcoro did not take into account the trampoline on amd64, |
976 |
when 'l'inux method was used. |
977 |
|
978 |
1.31 Tue Aug 30 23:31:33 CEST 2005 |
979 |
- some portability fixes/workarounds. |
980 |
|
981 |
1.3 Sat Aug 20 03:08:56 CEST 2005 |
982 |
- no code changes. module seems to work fine. |
983 |
- improve Coro::State docs, remove reference to nonexisting |
984 |
Coro::State::flush method. |
985 |
- no longer autodetect windows, present it as an option instead. |
986 |
|
987 |
1.2 Mon May 16 02:00:55 CEST 2005 |
988 |
- included libcoro.c earlier in State.xs, might improve portability. |
989 |
- use a faster and possibly more stable Coro::Cont implementation. |
990 |
- accept x86_64 in addition to amd64 for optimized linux-amd64 support. |
991 |
- fix bugs Coro::SemaphoreSet that could cause locks never to be freed. |
992 |
- fix bugs in CoroAPI.h and document it in Coro::MakeMaker. |
993 |
|
994 |
1.11 Thu Mar 3 18:00:52 CET 2005 |
995 |
- change of contact address. |
996 |
|
997 |
1.1 Tue Feb 22 20:51:16 CET 2005 |
998 |
- support [l]inux method on amd64. |
999 |
- allow some context switches while compiling/eval'ing. |
1000 |
|
1001 |
1.0 Tue Aug 10 03:47:27 CEST 2004 |
1002 |
- Event 0.89 fixes the bug again. |
1003 |
- fix the remaining(??) memleak. I didn't free the cache-AV for |
1004 |
padlists, so one AV per created anon-sub leaked. |
1005 |
|
1006 |
0.97 Fri May 14 15:23:32 CEST 2004 |
1007 |
- remove stupid gcc extension that was an experiment only anyway. |
1008 |
|
1009 |
0.96 Thu May 13 18:09:29 CEST 2004 |
1010 |
- tell people if they have yet another broken Event variant. |
1011 |
- made Coro to work _better_ with threads (it seems that, as long |
1012 |
as you use Coros in one thread only everything will work fine. |
1013 |
Looking at the perl source the problem might be missing locking |
1014 |
between Coro and some perl internal routines. That's not easily |
1015 |
fixable). |
1016 |
- (hopefully) got rid of the static xnext inside transfer. |
1017 |
|
1018 |
0.95 Sun Feb 15 03:20:28 CET 2004 |
1019 |
- removed Coro::State::flush, implemented a new and much |
1020 |
faster caching mechanism by attaching magic to the CV. |
1021 |
- a memleak with (real) closures remains. |
1022 |
- dramatically reduced size of stacks to 65536 (linux/x86), after |
1023 |
observing that even myhttpd never had more than a kilobyte |
1024 |
of stack in use (stack is still only physically allocated in |
1025 |
pagesize increments for systems suporting mmap). |
1026 |
- fix for a "cygwin-64" architecture added, proposed by Stefan Traby. |
1027 |
- fix for threaded perl. |
1028 |
|
1029 |
0.9 Sun Nov 23 04:32:39 CET 2003 |
1030 |
- fix a few very hard to track down but (of course) stupid |
1031 |
memory leaks. |
1032 |
- stringify version number to avoid locale problems :(. |
1033 |
- perl 5.9.0 does not have SvPADBUSY, reported by Scott Walters, |
1034 |
hopefully ignoring it "just works". |
1035 |
|
1036 |
0.8 Wed Nov 5 19:38:40 CET 2003 |
1037 |
- port to perl5.005_03, but only 5.8.x+ is supported! |
1038 |
- honor LocalAddr even without LocalPort in Coro::Socket. |
1039 |
|
1040 |
0.7 Tue May 27 03:12:38 CEST 2003 |
1041 |
- the version jump indicates some level of testing, not gobs |
1042 |
of new features. |
1043 |
- uh... I found the prompt function in ExtUtils::MakeMaker. |
1044 |
Highly correct stuff, that is... |
1045 |
- fixed(?) a bug with die's in coroutines causing "panic: top_env". |
1046 |
the fix is not well understood by the author, so beware :(. |
1047 |
|
1048 |
0.652 Thu May 8 02:54:46 CEST 2003 |
1049 |
- Applied patch by Slaven Rezic to set default to "s" on FreeBSD, |
1050 |
cause version 4 doesn't have ucontext. |
1051 |
- Benjamin Reed reported that setjmp works fine on darwin, |
1052 |
so preselect it. |
1053 |
|
1054 |
0.651 Sat Mar 29 15:00:23 CET 2003 |
1055 |
- fix a bug in Coro::Handle where some bytes could get lost |
1056 |
on reading, reported by jason@nichego.net. |
1057 |
|
1058 |
0.65 Sun Mar 23 00:08:26 CET 2003 |
1059 |
- added a README.linux-glibc. |
1060 |
- new module Coro::Select. |
1061 |
- also save/restore PL_comppad, fixes segfaults with 5.8.1. |
1062 |
(I never claimed that I know what I am doing ;). |
1063 |
- set default to setjmp/longjmp on non-x86-linux. |
1064 |
|
1065 |
0.6 Thu Nov 21 11:09:06 CET 2002 |
1066 |
- made lazy context switching the default. |
1067 |
- fixed the bug where SemaphoreSet::guard |
1068 |
was the same as timed_guard and timed_guard was missing. |
1069 |
- fix a memleak in Coro::Timer. |
1070 |
- reclassified context sharing as not experimental. |
1071 |
|
1072 |
0.534 Sun Apr 14 03:05:12 CEST 2002 |
1073 |
- fixed backspace => tab in header parsing (myhttpd). |
1074 |
- added eg/readline, for elmex. |
1075 |
- Coro::Event now calls ->start on first call instead of |
1076 |
->again, which created wrong timeouts for the first ->next. |
1077 |
- fixed a bug where Coro::Socket returned a closed socket instead |
1078 |
of nothing on ECONNREFUSED and similar error conditions. |
1079 |
|
1080 |
0.533 Mon Feb 18 18:49:40 CET 2002 |
1081 |
- adapt to finally working Event-0.85. |
1082 |
- fixed buggy event initialization (trapped under windows, but how |
1083 |
could it possibly have worked anywhere?) |
1084 |
|
1085 |
0.532 Wed Jan 16 02:45:32 CET 2002 |
1086 |
- removed the reference to pp_entersub, might work on |
1087 |
(some) win32 perls now (testsuite works under cygwin, |
1088 |
without Event, which freezes). |
1089 |
|
1090 |
0.531 Mon Dec 10 22:18:44 CET 2001 |
1091 |
- Fixed a bug in SemaphoreSet::timed_down. |
1092 |
|
1093 |
0.53 Tue Nov 27 21:11:13 CET 2001 |
1094 |
- some tests for Event. |
1095 |
- slightly different internal architecture to get refcnt into the object |
1096 |
and not the reference. might fix a few bugs, certainly did introduce |
1097 |
new ones. |
1098 |
- Coro::Timer (independent of Event). |
1099 |
- new timed_wait functions for Coro::Signal, Semaphore, SemaphoreSet. |
1100 |
|
1101 |
0.52 Tue Nov 6 21:36:18 CET 2001 |
1102 |
- ported to cygwin (trivial). |
1103 |
patch by Gerrit P. Haase <gp@familiehaase.de>. |
1104 |
- small setjmp code fix by Sullivan.DanielJ@epamail.epa.gov. |
1105 |
|
1106 |
0.51 Thu Nov 1 20:39:01 CET 2001 |
1107 |
- terminate/cancel now work properly (otherwise termination |
1108 |
could cause a "next coroutine is not and contains not..." |
1109 |
error. |
1110 |
- added Coro::Socket::shutdown. |
1111 |
- Coro::Event::loop no is the same as Event::loop. |
1112 |

1113 |
|
1114 |
0.5 Fri Sep 28 16:15:35 CEST 2001 |

1117 |
in various modules. |
1118 |
- splendid use of "no warnings" scattered throughout. |
1119 |

0.49 Sun Sep 16 02:42:45 CEST 2001 |
1122 |
- changed some method calls to function calls for speed |

inside Coro::Handle. |
1124 |
- make Coro::Handle use an array instead of a hash for |
1125 |
speed reasons. |
1126 |
- IRIX mystery solved: it's SGI's NT, after all: "standard, huh?". |
1127 |
sjlj and ucontext should now work. |
1128 |
- IRIX-specific port for libcoro. |
1129 |
- swapped order of accept results to match IO::Socket. |
1130 |
- changed getsock/peername to sock/peername to match IO::Socket. |
1131 |
- fixed a bug that caused segfault when returning to main task |
1132 |

- other bugfixes. |
1134 |
|
1135 |
0.45 Sun Sep 2 02:54:01 CEST 2001 |
1136 |

1142 |
syntax. |
1143 |

1144 |
- new simple priority system. |
1145 |
- implemented Coro::Event using XS, almost four times faster! |

1147 |
|
1148 |
0.13 Wed Aug 8 16:53:07 CEST 2001 |
1149 |
- new method Coro::Handle::readline. |
1150 |

- much better Coro::Socket support. |
1158 |
|
1159 |
0.12 Fri Jul 27 04:19:01 CEST 2001 |
1160 |
- do not use mmap if neither MAP_ANON nor MAP_ANONYMOUS is defined. |
1161 |
- very experimental stack sharing algorithm. not 100% safe but |
1162 |
should work well in practise ;) |
1163 |
- added Coro::RWLock. |
1164 |
- Coro::Specific now works. |
1165 |
|
1166 |
0.11 Tue Jul 24 22:49:21 CEST 2001 |
1167 |

1170 |
|
1171 |
0.1 Tue Jul 24 01:47:53 CEST 2001 |
1172 |
- release candidate 3. A rather new internal structure :( |
1173 |
- the great renaming: Damian Conway gave me a suitable replacement |
1174 |
for yield. |
1175 |
- added Coro/libcoro, a portable coroutine implementation for C |
1176 |
(not even perl-dependent!!!), which can be used by Coro::State. |
1177 |
- renamed SAVE_DEFSV (on xs-level only) to avoid symbol clash in |
1178 |
perl-5.6. |
1179 |

1180 |
- the idle process is now overriden |
1181 |
by default in Coro::Event. |
1182 |
- Coro::Channel now enforces the size. |
1183 |
- canceling events now works in all cases. |
1184 |
- Coro state now include $_ and $@. |
1185 |
- yet another bug workaround that I do not really understand :( |
1186 |
- new module Coro::Event::IO (very undocumented) to do |
1187 |
non-blocking i/o. |
1188 |
- performance tuning. |
1189 |
|
1190 |
0.08 Thu Jul 19 06:13:25 CEST 2001 |
1191 |
- release candidate 2 (new functionality). |
1192 |
- add Coro::State::flush function. |
1193 |
- transfer now supports a flags value (mostly for speed ATM). |
1194 |
- might compile and work in the presence of threads now. |
1195 |
- continuations have a saner syntax. |
1196 |
- no more memleaks. |
1197 |
|
1198 |
0.07 Tue Jul 17 17:40:18 CEST 2001 |
1199 |
- release candidate 1 ;) |
1200 |
- slightly nicer code. |
1201 |
- fixed a scheduling bug in Coro::Event. |
1202 |
|
1203 |
0.06 Tue Jul 17 04:23:24 CEST 2001 |
1204 |
- ok, I found the showstopper - the same sub must not be |
1205 |
re-entered in two different coroutines, otherwise => crash. I |
1206 |
see no easy solution to this problem, except by walking the call |
1207 |
chaing and saving/restoring the cv's, which is what I do now. |
1208 |
- memory leaks still latent, especially at thread termination. |
1209 |
- Coro::Event now works (haha). |
1210 |
|
1211 |
0.05 Sun Jul 15 17:32:20 CEST 2001 |
1212 |
- fixed a few issues in Coro::Event. |
1213 |
- I forgot to include Coro::Event in 0.04 :(:(:( |
1214 |
|
1215 |
0.04 Sun Jul 15 05:24:59 CEST 2001 |
1216 |
- @_ is now properly localized. |
1217 |
- Coro::State is now easier subclassable. |
1218 |
- Coro::Cont now coroutine-aware. |
1219 |
- Coro::Specific is a low-overhead module to create |
1220 |
coroutine-specific vars. |
1221 |
- Coro::Event provides a simple interface to Event. |
1222 |
|
1223 |
0.03 Fri Jul 13 14:51:52 CEST 2001 |
1224 |
- transfer() now implemented in XS (beware). |
1225 |
- new module Coro::Cont for really faked continuations. |
1226 |
- big internal architecture changes: Coro::State is now |
1227 |
really low-level and can thus be used to implement other |
1228 |
interesting things, While "Coro::" implements a process-like |
1229 |
model. Still crude and subject to change. |
1230 |
- $_ and $@ are no longer being localized. |
1231 |
|
1232 |
0.02 Tue Jul 10 01:38:17 CEST 2001 |
1233 |
- implemented "async" attribute. |
1234 |
- $_ and $@ are now localized. |
1235 |
- added Coro::Channel. |
1236 |
- more testcases, still no docs. |
1237 |
|
1238 |
0.01 Tue Jul 3 02:18:41 CEST 2001 |
1239 |
- original version; copied from Convert::Scalar. |
