|
|
8 | - INCOMPATIBLE CHANGE: unreferenced coro objects will now be |
|
|
9 | destroyed and cleaned up automatically (e.g. async { schedule }). |
|
|
10 | - implement a JIT compiler for part of the thread switch code, |
|
|
11 | which gives a 50% speed improvement on threaded perls, and |
|
|
12 | about 4% on non-thraeded perls (so threaded perls now finally |
|
|
13 | reach about half the speed of non-threaded perls). |
|
|
14 | - slightly modernise Coro::Intro, add section about rouse functions. |
|
|
15 | - avoid DEFSV and ERRSV, giving another 10% improvement |
|
|
16 | in thread switching. |
|
|
17 | - Coro::State->is_destroyed is now called is_zombie. |
|
|
18 | - implement a Coro->safe_cancel method that might fail, but |
|
|
19 | cancels in a "safer" way if it succeeds. |
|
|
20 | - add preliminary support for DEBUGGING perls. |
|
|
21 | - get rid of two hash-accesses when initialising a new Coro - this |
|
|
22 | speeds up coro creation by almost a factor of two. |
|
|
23 | - croak when a coro that is being cancelled tries to block |
|
|
24 | (e.g. while executing a guard block), instead of crashing or |
|
|
25 | deadlocking. |
|
|
26 | - use a more robust and also faster method to identify Coro::State |
|
|
27 | objects - speeds up everything a bit. |
|
|
28 | - implement Coro->cancel in XS for a 20% speed improvement, and to |
|
|
29 | be able to implement mutual cancellation. |
|
|
30 | - speed up context switches by a percent or two by more efficiently |
|
|
31 | allocating context stack entries. |
|
|
32 | - implement Coro->join and Coro->on_destroy in XS for a speedup and |
|
|
33 | a reduction in memory use. |
|
|
34 | - cancelling a coro while it itself is cancelling another coro is |
|
|
35 | now supported and working, instead of triggering an assertion. |
|
|
36 | - be a bit more crash-resistant when calling (buggy) on_destroy |
|
|
37 | callbacks (best effort). |
|
|
38 | - move on_destroy into the slf_frame, to allow extension slf |
|
|
39 | functions to have destructors. |
|
|
40 | - get rid if coro refcounting - simply crash in other interpreter |
|
|
41 | threads by nulling the pointers on clone. |
|
|
42 | - simplify warn/die hook handling when loading Coro - the convoluted |
|
|
43 | logic seems to be no longer neccessary. |
|
|
44 | - use libecb instead of our own home-grown gcc hacks. |
|
|
45 | - document alternatives to Coro::LWP. Please use them :) |
|
|
46 | - work around another mindless idiotic NEEDLESS bug in openbsd/mirbsds |
|
|
47 | sigaltstack. Really. wine suffers from it, erlang suffers from it, |
|
|
48 | and it's known since at least 2006. |
|
|
49 | |
|
|
50 | 5.372 Wed Feb 23 06:14:30 CET 2011 |
|
|
51 | - apparently mingw doesn't provide a working gettimeofday, try to |
|
|
52 | work around that by relying on Time::HiRes (indirectly brought to |
|
|
53 | my attention by Max Maischein). |
|
|
54 | - fix some portability issues when Time::HiRes was used. |
|
|
55 | |
|
|
56 | 5.371 Mon Feb 21 14:36:08 CET 2011 |
|
|
57 | - backport to windows process emulation code again. |
|
|
58 | |
|
|
59 | 5.37 Sat Feb 19 07:49:44 CET 2011 |
|
|
60 | - add a big "Coro thread life cycle" section to "man Coro". |
|
|
61 | - try a tentative workaround against the breakage that 5.13 has |
|
|
62 | introduced without depreciation period. sigh. |
|
|
63 | - no longer use Time::HiRes if gettimeofday is available, which |
|
|
64 | saves quite a lot of memory. |
|
|
65 | |
|
|
66 | 5.36 Sun Feb 13 05:33:41 CET 2011 |
|
|
67 | - automatically load Coro::Channel, Coro::RWLock, Coro::Semaphore, |
|
|
68 | Coro::SemaphoreSet, Coro::Signal and Coro::Specific on first "new" |
|
|
69 | method call. |
|
|
70 | - undocument Coro::Timer::sleep and obsolete whole module. |
|
|
71 | - optimise Coro::Timer::timeout memory and cpu usage. |
|
|
72 | - slightly updated Coro::Intro for recent changes. |
|
|
73 | - do not initialise PL_dirty anymore. |
|
|
74 | |
|
|
75 | 5.25 Thu Nov 11 01:08:39 CET 2010 |
|
|
76 | - try a different approach on netbsd - netbsd 5 finally has marginally |
|
|
77 | working pthreads, but still broken ucontext/sigaltstack. |
|
|
78 | - openbsd 4.8 finally got their act together, Coro works out of the box |
|
|
79 | with asm, setjmp and pthreads (no change, just informational). |
|
|
80 | |
|
|
81 | 5.24 Sat Oct 23 11:27:12 CEST 2010 |
|
|
82 | - port to the EV 4.0 API. |
|
|
83 | - work around bugs in mingw32, making strawberry perl work |
|
|
84 | out of the box. |
|
|
85 | - correctly modify Coro::AIO function prototypes |
|
|
86 | so that they reflect the "no optional parameters" rule. |
|
|
87 | - "ported" libcoro to C++. |
|
|
88 | |
|
|
89 | 5.23 Mon May 17 18:50:42 CEST 2010 |
|
|
90 | - be more resistant to ordering changes when initialising |
|
|
91 | Coro::AnyEvent, Coro::EV and Coro::Event (reported by Matthias |
|
|
92 | Waldorf). |
|
|
93 | - document that perl 5.12 deliberately removed support for cloning. |
|
|
94 | |
|
|
95 | 5.22 Wed Apr 14 03:55:35 CEST 2010 |
|
|
96 | - correctly return udnef on errors in Coro::Handle::read/write |
|
|
97 | (testcase by Marc Mims). |
|
|
98 | - convert Coro::Util into a "perl compatibility wrapper" - the functions |
|
|
99 | are less useful now, but are drop-in replacements for existing |
|
|
100 | functions, listing better alternatives in the documentation. This also |
|
|
101 | fixes a bug in Coro::LWP which naively substituted Socket::inet_aton |
|
|
102 | with Coro::Util::inet_aton. |
|
|
103 | - do not override $Coro::idle unconditionally in Coro.pm, as other |
|
|
104 | modules could have provided their own idle coro already |
|
|
105 | (for exmaple, Coro::AnyEvent). |
|
|
106 | - fix Coro::Util::gethost* functions. |
|
|
107 | - Coro::Timer corretcly exports it's symbols (reported by Hideki Yamamura). |
|
|
108 | |
|
|
109 | 5.21 Wed Dec 16 07:19:51 CET 2009 |
|
|
110 | - automatically load Coro::AnyEvent when AnyEvent and Coro are used |
|
|
111 | together. |
|
|
112 | - add some examples on how to combine other event loops with Coro in |
|
|
113 | Coro::AnyEvent, and how to run it (and not to block). Seems to be |
|
|
114 | the most common source of confusion. |
|
|
115 | - try to catch people naively blocking in an event callback. |
|
|
116 | - work around the perl filehandle bug issue in conjunction with |
|
|
117 | older common::sense (as indirectly pointed out by ZSystem). |
|
|
118 | - clarify the "not from signal handlers" section. |
|
|
119 | |
|
|
120 | 5.2 Sun Oct 4 14:54:24 CEST 2009 |
|
|
121 | - Coro::Storable destroyed the prototypes of the functions it wrapped. |
|
|
122 | - export rouse_cb and rouse_wait by default now. |
|
|
123 | - fix various prototype mismatches in Coro::AnyEvent and Coro::Handle. |
|
|
124 | - new method $state->swap_sv. |
|
|
125 | - added section on "windows process emulation" to the manpage, |
|
|
126 | after a not-so-fruitful (nor-friendly) "discussion" with chip |
|
|
127 | salzenberg (discussion implies arguments, but his only arguments |
|
|
128 | were ad-hominems, one wonders why he started it in the first |
|
|
129 | place). I hope this explains it well enough for him to understand, |
|
|
130 | and maybe well enough for others to understand. |
|
|
131 | - use common::sense everywhere now. |
|
|
132 | - idle callbacks are no longer supported, use idle coros instead. |
|
|
133 | - print a thread listing when a deadlock is detected. |
|
|
134 | |
|
|
135 | 5.17 Sat Aug 22 23:09:31 CEST 2009 |
|
|
136 | - work around a bug in the perl debugger causing crashes |
|
|
137 | when running under the debugger by marking _pool_handler as nodebug. |
|
|
138 | - speed up Coro::async considerably. |
|
|
139 | - try some hacks to get netbsd to work "more often" - their broken |
|
|
140 | setjmp/longjmp, ucontext *and* phtreads are really hard on Coro. |
|
|
141 | - convert Coro to AE 5.0 API. |
|
|
142 | |
|
|
143 | 5.162 Tue Jul 28 04:04:03 CEST 2009 |
|
|
144 | - perl 5.8.2 is now minimum requirement. |
|
|
145 | - skip t/19_handle.t on broken windows perls. |
|
|
146 | |
|
|
147 | 5.161 Wed Jul 22 04:47:38 CEST 2009 |
|
|
148 | - Coro::AnyEvent::poll could have a different prototype when EV was |
|
|
149 | used as backend (analyzed by Tatsuhiko Miyagawa). |
|
|
150 | - Coro::AnyEvent errornously initialised the event loop when loaded, |
|
|
151 | not on demand. |
|
|
152 | - try to workaround rare */t/01_unblock.t failures. |
|
|
153 | |
|
|
154 | 5.16 Tue Jul 21 01:44:37 CEST 2009 |
|
|
155 | - Coro::AnyEvent failed to hook into the event loop |
|
|
156 | when no threads had been readied between detecting |
|
|
157 | the event loop and actually running it. |
|
|
158 | - considerably speed up Coro::Select by taking avdantage |
|
|
159 | of AnyEvent > 4.8 and some other optimisations. |
|
|
160 | - implement paragraph readline mode in Coro::Handle |
|
|
161 | (based on patches by Zsbán Ambrus). |
|
|
162 | - replace WSAEINPROGRESS by WSAEWOULDBLOCK (reported |
|
|
163 | and analyzed by Yasuhiro MATSUMOTO). |
|
|
164 | - clarified libcoro license and copyright. |
|
|
165 | - someone stole my EXTRA_META!!! |
|
|
166 | - implement Coro::Select::patch_pp_sselect and it's brother, |
|
|
167 | for hardcode select overriding. |
|
|
168 | |
|
|
169 | 5.151 Mon Jul 6 05:41:57 CEST 2009 |
|
|
170 | - backport to windows process emulation code again (patch by |
|
|
171 | Yasuhiro MATSUMOTO). |
|
|
172 | - slightly update Coro::MakeMaker. |
|
|
173 | |
|
|
174 | 5.15 Tue Jun 30 10:28:06 CEST 2009 |
|
|
175 | - deprecate Coro::Socket, document how to get ipv6 support via |
|
|
176 | AnyEvent::Socket instead. |
|
|
177 | - implement signal->wait ($cb) interface, similar to semaphores. |
|
|
178 | - work around SvOK not supporting getmagic, so we have to getmagic |
|
|
179 | to test for undef :/ (reported by Matthias Waldorf). |
|
|
180 | - load Coro::AnyEvent in all modules using AnyEvent. |
|
|
181 | - work around perl corrupting our internal data structures, |
|
|
182 | reported by Tokuhiro Matsuno. |
|
|
183 | - enable per-coroutine real and cpu time gathering |
|
|
184 | (Coro::State::enable_times). |
|
|
185 | |
|
|
186 | 5.14 Wed Jun 24 01:37:48 CEST 2009 |
|
|
187 | - provide explicit functions to "cede" to the event loop in Coro::AnyEvent, |
|
|
188 | as this seems to have been a difficult concept (poll, sleep, idle, |
|
|
189 | idle_upto). |
|
|
190 | - add Coro::AnyEvent::readable/writable functions. |
|
|
191 | - clarify Coro::EV/Event/AnyEvent manpages. |
|
|
192 | - free per-thread global scalars in the thread calling ->cancel, to |
|
|
193 | avoid crashes when $_, $@ etc., are magical but some of those |
|
|
194 | had already been freed. |
|
|
195 | - "unexperimentalise" the callback interface for Coro::Semaphore. |
|
|
196 | - speed up ready queue management/context switching by using a linked |
|
|
197 | list instead of an array (~5-10%). |
|
|
198 | - implement "watch" command in Coro::Debug shells. |
|
|
199 | - for fun, implement time-slicing as an example in the manpage. |
|
|
200 | - if AnyEvent detects EV or Event, but we don't have Coro::EV or |
|
|
201 | Coro::Event, use the normal AnyEvent handling instead of dieing |
|
|
202 | (the same is true for Coro::Handle). |
|
|
203 | - properly document Coro::EV::timed_io_once. |
|
|
204 | - avoid unneccessary ->cancel calls in Coro::Handle. |
|
|
205 | - maybe make it work on mingw32 with win32 backend |
|
|
206 | (based on patch by Yasuhiro Matsumoto). |
|
|
207 | |
|
|
208 | 5.132 Fri May 29 09:00:39 CEST 2009 |
|
|
209 | - do not keep a reference to the argument itself in |
|
|
210 | Coro::Semaphore::guard, as it could change later. |
|
|
211 | - support SO_RCVBUF/SO_SNDBUF nonstandard Coro::Socket options, |
|
|
212 | should support a prepare callback. |
|
|
213 | |
|
|
214 | 5.131 Mon Mar 16 23:20:37 CET 2009 |
|
|
215 | - implement and document Coro->suspend, Coro->resume. |
|
|
216 | - fix Coro::Select implementation to not (often) close |
|
|
217 | the passed file descriptors (testcase provided by pippijn). |
|
|
218 | |
|
|
219 | 5.13 Mon Dec 15 21:51:42 CET 2008 |
|
|
220 | - EXPERIMENTAL: implement dynamic winds (on_enter/on_leave). |
|
|
221 | - don't set diehook to C<undef> but instead to NULL, to avoid |
|
|
222 | spurious warnings. |
|
|
223 | - fix a lot of bugs in Coro::SemaphoreSet. |
|
|
224 | - Coro::SemaphoreSet will less often create a semaphore needlessly. |
|
|
225 | - add Coro::SemaphoreSet::count and wait methods. |
|
|
226 | - take advantage of the new Guard module. |
|
|
227 | - deprecate Coro::guard. |
|
|
228 | - try to fix the dreaded 01_unblock tests once more. I hate it when |
|
|
229 | testsuites need more fixing than the code they are supposed to test. |
|
|
230 | - croak in more cases when a required callback isn't resolvable. |
|
|
231 | - fix some minor issues in Coro::State->call/eval. |
|
|
232 | - use current coroutine context instead of a temporary one |
|
|
233 | when temporarily switching to another coroutine. |
|
|
234 | - do not call C-level on_destroy handlers during global destruction, |
|
|
235 | to avoid needless segfaults. |
|
|
236 | |
|
|
237 | 5.12 Sun Dec 7 13:30:38 CET 2008 |
|
|
238 | - add default config for MirOS, which seems to be a bug-to-bug |
|
|
239 | compatible fork of openbsd ("world domination by releasing |
|
|
240 | openbsd cvs before the openbsd folks do it" or so :). |
|
|
241 | - free_padlist did destroy the names pad, not good, but didn't |
|
|
242 | seem to bother perl - this could fix issues such as eval "" |
|
|
243 | inside a function called from multiple coroutines. |
|
|
244 | - use a different method to detect destruction time. |
|
|
245 | - be more careful when freeing padlists just before global |
|
|
246 | destruction. |
|
|
247 | - fixed and expanded the call/cc example. |
|
|
248 | - renamed _terminate to _coro_run. |
|
|
249 | - new method Coro::Channel->shutdown. |
|
|
250 | - try pthreads on openbsd <4.4 (broken sigaltstack, will |
|
|
251 | pthreads fare better?). |
|
|
252 | - be less picky about destroying "a" running coroutine. |
|
|
253 | |
|
|
254 | 5.11 Tue Nov 25 21:49:05 CET 2008 |
|
|
255 | - DEBUGGING in 5.10.0 is a mess: it constantly flags perfectly |
|
|
256 | working code with failed assertions, introducing more bugs than |
|
|
257 | it fixes, requiring elaborate workarounds :( |
|
|
258 | |
|
|
259 | 5.1 Mon Nov 24 08:54:59 CET 2008 |
|
|
260 | - wrote a small introductory tutorial - Coro::Intro. |
|
|
261 | - convert Coro::Timer, Coro::Select and Coro::Util to rouse API. |
|
|
262 | - Coro::Select did errornously dup the file descriptors |
|
|
263 | and didn't work with all AnyEvent backends. |
|
|
264 | - Coro::Select wasn't imported correctly form Coro::LWP, causing blocking |
|
|
265 | LWP data transfers. |
|
|
266 | - disassociate c contexts from coro objects - this is agruably more |
|
|
267 | correct, but mostly allows sharing of cctxs between coro and state |
|
|
268 | objects, for added memory savings and speed increases. |
|
|
269 | - bumped $Coro::POOL_RSS up to 32kb by default. |
|
|
270 | - no longer set the optype to OP_CUSTOM, as B::* understandably |
|
|
271 | doesn't like this very much (and we *are* a type of entersub). |
|
|
272 | - implement state cloning, just to prove that call/cc can be done. |
|
|
273 | - automatically load Coro::AnyEvent in Coro::Handle. |
|
|
274 | - wrap ->cancel calls in eval inside Coro::Handle as EV watchers |
|
|
275 | do not have this method (and don't need it either). |
|
|
276 | - speed up generic anyevent methods in Coro::Handle by using rouse |
|
|
277 | callbacks. |
|
|
278 | - allow coroutines in $Coro::IDLE, speeding up Coro::AnyEvent and |
|
|
279 | others. It also makes the debugger happier, as you can trace |
|
|
280 | through the idle threads now. |
|
|
281 | - add comppad_name* and hints ($^H, %^H) to per-thread variables. |
|
|
282 | - eg/event was pretty broken. |
|
|
283 | - better 5.8.6 compatibility. |
|
|
284 | |
|
|
285 | 5.0 Thu Nov 20 10:35:05 CET 2008 |
|
|
286 | - NEW ARCHITECTURE: use the latest 4.x version if you experience |
|
|
287 | stability issues. |
|
|
288 | - bump API version to 7 - all dependents must be recompiled. |
|
|
289 | - removed timed_* functions - they were not being used anyways |
|
|
290 | and should be replaced by a more generic mechanism - |
|
|
291 | and were annoying to support anyways :) |
|
|
292 | - removed SemaphoreSet's waiter method - use sem method instead. |
|
|
293 | - Coro::Semaphore->adjust didn't correctly wake up enough waiters. |
|
|
294 | - async_pool did free a scalar value twice |
|
|
295 | ("Attempt to unreference..."). |
|
|
296 | - fix a longstanding bug where calling terminate on a coro that |
|
|
297 | was waiting for a semaphore that was just becoming available |
|
|
298 | would cause a deadlock (semaphore would get into a state where |
|
|
299 | it was available but waiters were still blocked). |
|
|
300 | - calling throw on a coroutine that is waiting for a semaphore will |
|
|
301 | no longer make it acquire the semaphore (and thus leak a count). |
|
|
302 | - perl's process emulation is now not even theoretically supported |
|
|
303 | anymore. |
|
|
304 | - new functions Coro::rouse_cb and Coro::rouse_wait for easier |
|
|
305 | conversion of callback-style to blocking-style. |
|
|
306 | - new methods $coro->schedule_to and ->cede_to, to specifically |
|
|
307 | schedule or cede to a specific coroutine. |
|
|
308 | - new function Coro::Semaphore::wait. |
|
|
309 | - use named constants in Coro::Channel (Richard Hundt). |
|
|
310 | - directly patch the entersub opcode calling SLF functions (cede, |
|
|
311 | transfer and so on). this does speed up context switching, but |
|
|
312 | more importanly, it frees us from the hardcoded behaviour of |
|
|
313 | entersub, so we might actually be able to return something from |
|
|
314 | those functions and atcually create new ones. |
|
|
315 | - take advantage of __builtin_frame_address on gcc. |
|
|
316 | - expose THX in coroapi (not sure whether this was a wise decision, |
|
|
317 | as "threaded" perls are running at half speed anyways). |
|
|
318 | - implement execute_slf (schedule-like-function) interface that makes |
|
|
319 | it possible to implement schedule-like-functions in XS. |
|
|
320 | - use new SLF interface to massively speed up Coro::EV by roughly a |
|
|
321 | factor of two. |
|
|
322 | - used new SLF interface to massively speed up Coro::Semaphore by a |
|
|
323 | factor of three. |
|
|
324 | - used new SLF interface to speed up Coro::AIO by roughly a factor of |
|
|
325 | four and reduce its memory usage considerably. |
|
|
326 | - implement Coro::SemaphoreSet purely in terms of Coro::Semaphore, |
|
|
327 | for a nice speedup and vastly more correct behaviour. Also implement |
|
|
328 | a new method "sem" to get at the underlying semaphore object. |
|
|
329 | - implement Coro::Channel in terms of Coro::Semaphore, for a moderate |
|
|
330 | (in comparison) 20-40% speedup. |
|
|
331 | - used new SLF interface to reimplement Coro::Signal gaining |
|
|
332 | some unknown (because I was too lazy), but certain, speedup, and also |
|
|
333 | making signals reliable for the first time. |
|
|
334 | - used new SLF interface and other optimisations to speed up async_pool |
|
|
335 | by a factor of two. It also doesn't rely on perl's exception mechanism |
|
|
336 | to exit anymore. The overhead for terminating an async_pool, coro over |
|
|
337 | a normal async is now very small. |
|
|
338 | - sped up coroutine creation/destruction by 40%. |
|
|
339 | - forgot to include Coro/libcoro/README in the dist for all these years. |
|
|
340 | - work around a freebsd pthreads bug (manual testcancel is required as |
|
|
341 | pthread_cond_wait isn't a cancellation point on freebsd). |
|
|
342 | - use new rouse functions to speed up and simplify Coro::BDB. |
|
|
343 | - make "prefer perl native functions" work with threaded perls. |
|
|
344 | - condense Coro::Debug ps output, hint at v and w flags. |
|
|
345 | - (libcoro) lots of minor cleanups and portability improvements. |
|
|
346 | |
|
|
347 | 4.914 Wed Nov 19 12:54:18 CET 2008 |
|
|
348 | - fix a disastrous bug in the readline optimisation |
|
|
349 | introduced in 4.801. |
|
|
350 | |
|
|
351 | 4.913 Sat Nov 15 07:58:28 CET 2008 |
|
|
352 | - async_pool did free a scalar value twice |
|
|
353 | ("Attempt to unreference..."). |
|
|
354 | |
|
|
355 | 4.912 Thu Nov 13 18:31:23 CET 2008 |
|
|
356 | - minor cleanups. |
|
|
357 | - use much larger stacks on linux and perl < 5.8.8. |
|
|
358 | - Coro::Debug::new_unix_server did not unlink the socket |
|
|
359 | when destroyed. |
|
|
360 | |
|
|
361 | 4.911 Tue Nov 11 04:26:17 CET 2008 |
|
|
362 | - "port" to threaded perls. |
|
|
363 | |
|
|
364 | 4.91 Mon Nov 10 05:36:38 CET 2008 |
|
|
365 | - the ->throw exception object no longer leaks. |
|
|
366 | - creating a new cctx leaked a scopestack entry (memleak). |
|
|
367 | - new coroutines didn't get created with a zero flags field |
|
|
368 | (unknown impact). |
|
|
369 | - calling ->throw on a not-yet-started coroutine should now work |
|
|
370 | instead of being ignored. |
|
|
371 | - ->throw is now supported on Coro::State objects. |
|
|
372 | - clean up cctx creation code a bit. |
|
|
373 | - entersub is actually a UNOP, not a LOGOP (not a bugfix). |
|
|
374 | |
|
|
375 | 4.9 Sat Nov 8 17:45:27 CET 2008 |
|
|
376 | - (libcoro) did not preserve rbp with CORO_ASM (we are getting there). |
|
|
377 | - (libcoro) no longer leak threads in the experimental pthread backend, |
|
|
378 | also speed it up considerably. |
|
|
379 | - (libcoro) do not rely on makecontext passing void *'s unscathed. |
|
|
380 | - fix compiletime dependencies on libcoro in the Makefile. |
|
|
381 | - cctx_count wasn't always updated properly. |
|
|
382 | - Coro::State::cctx_stacksize wasn't applied correctly. |
|
|
383 | - new function Coro::State::cctx_max_idle. |
|
|
384 | - the default max number of idle C contexts is now 4. |
|
|
385 | - (libcoro) try harder to get _setjmp/_longjmp. |
|
|
386 | - (libcoro) cleanup and extend the libcoro API to officially |
|
|
387 | allow the creation of empty source contexts. |
|
|
388 | - very experimental workaround for the totally broken netbsd platform. |
|
|
389 | - tried to hack around openbsd bugs. |
|
|
390 | |
|
|
391 | 4.804 Wed Nov 5 16:36:00 CET 2008 |
|
|
392 | - Coro::Debug::new_unix_server would not create a non-blocking listening |
|
|
393 | socket, sometimes causing freezes. |
|
|
394 | - (libcoro) fix misaligned stack points for setjmp and assembly |
|
|
395 | methods, which can cause crashes on x86/x86_64 with a sufficiently |
|
|
396 | aggressive compiler. |
|
|
397 | - new function: Coro::Debug::new_tcp_server. |
|
|
398 | - move ->throw into the Coro class because it only works on coro objects. |
|
|
399 | |
|
|
400 | 4.803 Mon Nov 3 17:16:12 CET 2008 |
|
|
401 | - (libcoro) use a global asm statement to become independent of gcc |
|
|
402 | otpimisations for CORO_ASM (thanks to pippijn for the idea). |
|
|
403 | - try to workaround yet another broken bsd, this time dragonfly. |
|
|
404 | |
|
|
405 | 4.802 Thu Oct 30 10:56:12 CET 2008 |
|
|
406 | - support -fno-omit-frame-pointer on x86 with the assembly method. |
|
|
407 | - tune 01_unblock.t tests a bit. |
|
|
408 | |
|
|
409 | 4.801 Wed Oct 22 18:33:37 CEST 2008 |
|
|
410 | - improve readline speed for very long "lines". |
|
|
411 | - backport to 5.8.8. |
|
|
412 | |
|
|
413 | 4.8 Thu Oct 2 13:34:40 CEST 2008 |
|
|
414 | - new function Coro::AIO::aio_wait. |
|
|
415 | - Coro.:AIO and Coro::BDB now "use Coro::AnyEvent". |
|
|
416 | - greatly speed up and reduce memory usage of Coro::AIO requests. |
|
|
417 | - implement some other µ-optimisations. |
|
|
418 | |
|
|
419 | 4.749 Mon Sep 29 14:40:12 CEST 2008 |
|
|
420 | - port to slow and broken pseudo-threaded perls. (courtesy pippijn). |
|
|
421 | |
|
|
422 | 4.748 Sat Sep 27 14:03:19 CEST 2008 |
|
|
423 | - implement, but do not document, PerlIO::cede(granularity). |
|
|
424 | - Coro::Storable forgot to wrap Storable::pstore. |
|
|
425 | - work around the multitude of leaks and memory corruption |
|
|
426 | bugs in PerlIO::via by using our own C-level perliol. As a side |
|
|
427 | effect, Coro::Storable is now much, much, much faster. |
|
|
428 | |
|
|
429 | 4.747 Tue Sep 23 01:59:41 CEST 2008 |
|
|
430 | - fix a per-cv memleak (one empty array was leaked per |
|
|
431 | code reference). |
|
|
432 | - avoid a crash in coro->call|rss when the coroutine was already |
|
|
433 | destroyed (most noticably when using Coro::Debug::ps :) |
|
|
434 | - also protect *Storable::FILE. |
|
|
435 | - push up default storable granularity to 20ms. |
|
|
436 | |
|
|
437 | 4.746 Sun Sep 21 03:22:20 CEST 2008 |
|
|
438 | - be more insistent on locking Storable against reentrancy |
|
|
439 | in Coro::Storable. |
|
|
440 | - move swap_def?v and throw to Coro::State, as documented. |
|
|
441 | |
|
|
442 | 4.745 Thu Jul 24 00:14:38 CEST 2008 |
|
|
443 | - remove debugging code related to MgPV_nolen_const, also try to |
|
|
444 | make it compile with perl 5.8.6 (yes, apple apparently loves |
|
|
445 | outdated software). Reported by John S. |
|
|
446 | |
|
|
447 | 4.744 Tue Jul 8 22:06:35 CEST 2008 |
|
|
448 | - correctly provide default DIE/WARN handlers as documented. |
|
|
449 | - also overwrite PL_vtbl_sigelem.svt_clear, even though current |
|
|
450 | implementations inside perl work fine for us. |
|
|
451 | |
|
|
452 | 4.743 Mon Jun 16 00:21:57 CEST 2008 |
|
|
453 | - when using Coro::EV without running EV::loop it could |
|
|
454 | result in busy-waiting for events, this has been fixed. |
|
|
455 | - reduce codesize and improve performance by using EV_DEFAULT_UC. |
|
|
456 | |
|
|
457 | 4.742 Sat May 31 14:10:21 CEST 2008 |
|
|
458 | - implement a workaround for (some) perl <5.8.8 versions. |
|
|
459 | - require EV 3.3+. |
|
|
460 | |
|
|
461 | 4.741 Fri May 30 23:33:09 CEST 2008 |
|
|
462 | - tell netbsd how utterly broken their imitation of an OS is |
|
|
463 | and refuse to build by default if pthreads are in use. |
|
|
464 | - switch to "s" method on all bsd's by default, as their ucontext |
|
|
465 | stuff seems just too broken. |
|
|
466 | - fix a bug in Coro::Select. |
|
|
467 | |
|
|
468 | 4.74 Thu May 29 20:05:31 CEST 2008 |
|
|
469 | - do not test Coro::LWP for lack of dependencies. |
|
|
470 | - do not test Coro::Select for lack of working perls. |
|
|
471 | |
|
|
472 | 4.73 Thu May 29 2008 |
|
|
473 | - fix a bug in Coro::EV which would cause it to block despite |
|
|
474 | there being runnable coroutines. |
|
|
475 | - sprinkle "no warnings" freely over everything, also suppress |
|
|
476 | warnings for some other modules. |
|
|
477 | - fix typo in WSAEWOULDBLOCK. |
|
|
478 | |
|
|
479 | 4.72 Sun May 25 05:14:36 CEST 2008 |
|
|
480 | - tweak META.yaml a bit, unfortunately, there is no documented way |
|
|
481 | to have optional dependencies with CPAN. doh :( |
|
|
482 | - avoid running some tests on windows because they would fail due to |
|
|
483 | perl bug (broken fork, broken pipes...). |
|
|
484 | - work around perl on windows bugs where perl returns undocumented |
|
|
485 | error codes for sysread, syswrite etc. by taking advantage |
|
|
486 | of AnyEvent's workaround for that problem. |
|
|
487 | - use AnyEvent::Util::fh_nonblocking in Coro::Handle to work around |
|
|
488 | a common perl implementation bug on windows. |
|
|
489 | - use unix domain sockets in testsuite to work around |
|
|
490 | common perl implementation bugs on widows (they are emulated by |
|
|
491 | tcp sockets on windows. ugh.) |
|
|
492 | |
|
|
493 | 4.71 Sat May 24 20:01:27 CEST 2008 |
|
|
494 | - fix a bug in Coro::AnyEvent ("Usage: Coro::AnyEvent::_schedule()"). |
|
|
495 | - take advantage of async name resolution of AnyEvent::Util. |
|
|
496 | - work around brutal inet_aton override in Coro::LWP. |
|
|
497 | - take advantage of the readyhook in Coro::EV, for smoother |
|
|
498 | scheduling. |
|
|
499 | |
|
|
500 | 4.7 Sun May 11 00:32:19 CEST 2008 |
|
|
501 | - completely reworked the Coro manpage. |
|
|
502 | - added Coro::AnyEvent, generic event loop integration. |
|
|
503 | - implement cancel, ready and kill commands in Coro::Debug. |
|
|
504 | - document find_coro in Coro::Debug. |
|
|
505 | - incompatible change: rename has_stack to has_cctx. |
|
|
506 | - Coro::AIO and Coro::BDB no longer force event model detection, |
|
|
507 | use AnyEvent::AIO and AnyEvent::BDB. |
|
|
508 | |
|
|
509 | 4.6 Sat Apr 26 10:05:14 CEST 2008 |
|
|
510 | - INCOMPATIBLE CHANGE: sub/code attributes are no longer supported |
|
|
511 | by the Coro module. It was a mistake to have it in the first place. |
|
|
512 | - (experimental) support for activestate perl 5.10 (method "w"). |
|
|
513 | - (experimental) support for strawberry perl (method "a"). |
|
|
514 | - coro_sigelem_set did not return a value although it had to, |
|
|
515 | actual impact unknown. |
|
|
516 | |
|
|
517 | 4.51 Mon Apr 14 13:28:27 CEST 2008 |
|
|
518 | - make it compile again on 5.8. |
|
|
519 | |
|
|
520 | 4.50 Thu Apr 10 09:43:17 CEST 2008 |
|
|
521 | - I did it twice! (see 4.49). |
|
|
522 | |
|
|
523 | 4.49 Sun Apr 6 21:23:31 CEST 2008 |
|
|
524 | - grr, instead of compiling the recent changes on 5.10 only they |
|
|
525 | were compiled on 5.8 only. |
|
|
526 | |
|
|
527 | 4.48 Sun Apr 6 20:36:46 CEST 2008 |
|
|
528 | - allow coroutine switches during eval's under 5.10.x, as it seems |
|
|
529 | the parser is a per-interpreter option now, so this is safe |
|
|
530 | (this might fix the odd crashing bug). |
|
|
531 | - drop support for 5.9.x versions: they are dead, jim. |
|
|
532 | |
|
|
533 | 4.47 Sun Apr 6 00:37:52 CEST 2008 |
|
|
534 | - force cctx allocation on API calls: we know we need to force one |
|
|
535 | and gcc actually manages to confuse our heuristic nowadays, |
|
|
536 | leading to crashes and worse. |
|
|
537 | - document force_cctx. |
|
|
538 | |
|
|
539 | 4.46 Fri Apr 4 22:05:43 CEST 2008 |
|
|
540 | - upgrade libcoro, resulting in pthread-backend (which was only created |
|
|
541 | to fulfill the rules of the programming languages shootout). |
|
|
542 | |
|
|
543 | 4.45 Thu Mar 13 11:55:36 CET 2008 |
|
|
544 | - fix a file leaking bug in eg/mhyttpd that would allow |
|
|
545 | downloading of any file (reported by oesi). |
|
|
546 | - fix deadlock bug in Coro::Channel (reported by Richard Hundt) |
|
|
547 | (also add testcase). |
|
|
548 | - support Broadcast option in Coro::Socket (patch by Richard Hundt, |
|
|
549 | apparently having loads of fun with that). |
|
|
550 | - implement $state->swap_defsv, ->swap_defav and document ->throw. |
|
|
551 | |
|
|
552 | 4.4 Wed Feb 13 16:44:29 CET 2008 |
|
|
553 | - only assume .cfi pseudo isns exist on GNU/Linux. |
|
|
554 | - add get_timed method to Coro::Channels. |
|
|
555 | - fixed Coro::Debug manpage. |
|
|
556 | - perl 5.11 compatbility improvement based on patch by |
|
|
557 | Andreas König. |
|
|
558 | |
|
|
559 | 4.37 Sun Jan 20 11:25:23 CET 2008 |
|
|
560 | - soften the check for an active parser for perl 5.10 (avoiding |
|
|
561 | "Coro::State::transfer called while parsing" in many cases). |
|
|
562 | |
|
|
563 | 4.36 Sun Jan 13 10:53:56 CET 2008 |
8 | - reset diehook when terminating from an async_pool as to not |
564 | - reset diehook when terminating from an async_pool as to not |
9 | trigger any __DIE__ handlers. |
565 | trigger any __DIE__ handlers. |

11 | 4.35 Sun Jan 13 04:14:13 CET 2008 |
567 | 4.35 Sun Jan 13 04:14:13 CET 2008 |
12 | - "bt" debug command now displays any exceptions |
