1 Revision history for Perl extension Coro.
2
3 TODO: better (earlier) error messages on broken transfer's
4 TODO: destroy gets only called on cancel: fix(?)
5
6 3.52
7 - add count accessor to Coro::Semaphore.
8 - add Coro::State::cctx_stacksize.
9
10 3.51 Sun Mar 4 14:18:04 CET 2007
11 - fixed a problem when you weakened references to Coro::State's
12 (patch by Yuval Kogman).
13
14 3.501 Wed Feb 28 12:44:07 CET 2007
15 - rename some global symbols as macosx from hell redefines
16 them without asking.
17
18 3.5 Tue Feb 13 20:22:53 CET 2007
19 - do AnyEvent model detection earlier, avoiding problems
20 caused by first using AnyEvent and later Coro::Event.
21 - implement and document Coro::Event event objects.
22 - fix a potential problem in Coro::Event causing crashes.
23 - initialise PL_comppad when creating a new coroutine,
24 avoids crashes on early coro destruction.
25
26 3.41 Mon Jan 22 19:19:49 CET 2007
27 - readline on Coro::Handle did not support undefined $/,
28 nor did it deliver partial lines on EOF or error.
29 - implement malloc fallback for stack allocation because
30 stupid broken idiotic OSX has a stupid broken
31 idiotic fits-the-whole-os mmap "implementation" and
32 my dick feels longer if Coro is portable even to
33 obsolete platforms.
34
35 3.4 Fri Jan 19 21:52:54 CET 2007
36 - remove t/09_timer.t, as it isn't really testing much
37 but was rather flaky in practise.
38 - async_pool coro would keep arguments and callback alive until
39 it was reused.
40 - cancellation of a coroutine could cause spurious idle calls
41 in cede_notself.
42
43 3.3 Sat Jan 6 03:45:00 CET 2007
44 - implement $coro->on_destroy.
45 - Coro::Event blocking semantics have been changed,
46 documented and - hopefully - improved.
47 - fix nice adding, not subtracting, from priority.
48 - fix ->prio and api_is_ready (patch by Mark Hinds).
49 - fixed an assert ("... == prev__cctx->idle_te")
50 that could errronously trigger.
51 - fix various large and small memleaks.
52 - use a (hopefully) more stable cancel implementation
53 that immediately frees the coroutine data.
54 - cede/cede_notself return a status now.
55 - added Coro::guard function.
56 - added a global coroutine pool for jobs (on my machine,
57 I can create and execute 48k simple coros/s with async,
58 and 128k coros with async_pool).
59 - Coro::AIO now uses the coroutine priority as io priority.
60
61 3.2 Fri Dec 22 05:07:09 CET 2006
62 - improve portability to slightly older perls.
63 - use cleaner coroutine destruction.
64 - simplify configuration for users.
65 - optionally (unrecommended) prefer perl functions over
66 their coro replacements.
67
68 3.11 Tue Dec 5 13:11:24 CET 2006
69 - fixed some bogus assert's, but as perl.h disables assert even
70 without NDEBUG (thank you very much), not too many people should
71 notice (that did include myself). Andreas König noticed, though :)
72 - do not save/restore PL_sortcxix on >= 5.9.x, it doesn't seem to have
73 it. Also noticed by Andreas König :)
74 - save/restore tainted status.
75 - verified to pass the testsuite on my 5.9.5.
76
77 3.1 Mon Dec 4 23:03:40 CET 2006
78 - INCOMPATIBLE CHANGE: $/ is now per-coroutine (but slow).
79 - incompatible change: transfer flags are now per-state.
80 - give a better error message on deadlock.
81 - document Coro::nready.
82 - enhanced testsuite.
83
84 3.01 Sun Dec 3 23:47:42 CET 2006
85 - forgot to include Coro::Timer.
86
87 3.0 Sun Dec 3 22:57:25 CET 2006
88 - the "FINALLY COMPLETELY STABLE" release (coming soon:
89 the "FAMOUS LAST WORDS" release).
90 - implement a new stack sharing algorithm, which uses a stack
91 pool (size currently hardcoded).
92 - make stack sharing mandatory (it no longer uses a heuristic).
93 - eval/die no longer cause weird problems under heavy use.
94 - Coro::Event could cause livelocks if it was used but
95 no Coro::Event watchers were used.
96 - Coro::Event now uses asynccheck as prepare does not
97 check for changed watchers.
98 - Coro::Event allows multiple waiting coros and will wake up one
99 per event.
100 - Coro::Event should be cleaner and more efficient now.
101 - new utility function Coro::unblock_sub.
102 - document the sad fact that Event is no longer reentrant.
103 - putting a coroutine into the ready queue twice could under
104 some circumstances lead to stack corruption.
105 - minor incompatibility: subclassing Coro::State is supported
106 directly now without going through a _coro_state member.
107 - state/coro switching is much faster now.
108 - very minor optimisations and code/documentation cleanup.
109 - avoid problems due to compiler inlining.
110 - removed timers from Coro::Timer -> use AnyEvent instead.
111 - replaced Coro::idle coroutine by (cleaner) idle handler.
112 - updated to newest libcoro.
113 - implement enhanced support for valgrind.
114 - implement is_ready and return value for ready.
115 - removed Coro::Cont, it was a misnomer (it's generators),
116 and it was somewhat annoying to get it right. Will come back
117 if somebody asks for it :)
118 - many ->wait methods and Coro::Event could return
119 spuriously without the event having happened.
120
121 2.5 Tue Nov 7 12:22:33 CET 2006
122 - made Coro::Util, Coro::Select, Coro::Handle and Coro::Socket
123 use AnyEvent, moved them to Coro/.
124 - added Coro::LWP which contains all the uglyness required to
125 make LWP non-blocking.
126 - should work with perl 5.9.x now (Andreas König made me do it).
127 - fixed another bug in Coro::Select when the timeout was undef.
128 - reuse PL_start_env for all coros, saves some memory per coroutine.
129 - manage PL_top_env differently, hopefully to avoid panic: top_env.
130 - timeout argument was not properly used in Coro::Socket.
131 - allow limited forms of subclassing in Coro::Handle/Coro::Socket.
132 - emulate undocumented(!) functionality of IO::Socket required
133 by LWP(!!).
134 - updated eg/lwp to work with newer lwp's.
135 - remove "FATAL: uncaught exception" prefix. Coroutines that die
136 kill the whole process, just as exceptions in the main "coroutine"
137 did already.
138
139 2.1 Wed Nov 1 23:01:13 CET 2006
140 - fix a long-standing bug in Coro::Select where select with
141 zero timeout would instead change the current default filehandle.
142 - use a simpler and hopefully more robust way to clone padlists
143 (uses less memory and a perl function instead of our own).
144 - coro can now create a stack guard area on many architectures.
145 - Coro::AIO properly reexports additional functions from IO::AIO.
146 - updated libcoro with a workaround for OS X,
147 pach and testing by Michael Schwern.
148
149 2.0 Tue Oct 24 05:47:17 CEST 2006
150 - support additional aio requests in Coro::AIO.
151
152 1.9 (never properly released due to a glitch)
153
154 1.8 Thu Feb 2 00:59:06 CET 2006
155 - applied suggested patch by SAMV to avoid problems during stupid
156 mark & sweep gc run.
157 - applied patch by Scott Walters for 5.9.3 compatibility.
158
159 1.7 Tue Dec 27 01:41:58 CET 2005
160 - added Coro::AIO, a thin wrapper around IO::AIO.
161 - improved Makefile.PL explanations.
162
163 1.6 Mon Dec 12 21:30:05 CET 2005
164 - additionally save PM_curpm might fix as-of-yet
165 unseen problems with regex matches being attributed to the
166 wrong package.
167 - add t/10_bugs.t, which currently checks against imho broken
168 perls that use 0.26MB of stack space per Perl_magic_get
169 invocation (newer linuxes) as opposed to the 0.0002MB perl
170 normally uses.
171 - make stacksize configurable for the ultimate debian experience.
172
173 1.51 Mon Dec 12 18:48:36 CET 2005
174 - remove debugging warn() accidentally left in Coro::Select.
175
176 1.5 Tue Nov 29 13:32:44 CET 2005
177 - use Coro::Event inside Coro::Select to avoid spurious deadlocks.
178 - fix Coro::Select 'select'.
179 - strict'ify some modules.
180 - libcoro errornously restored the SIGUSR2 handler to SIGUSR1.
181 - use XSLoader in selected modules.
182 - remove some 5.6 compatibility cruft.
183
184 1.4 Tue Sep 6 00:11:05 CEST 2005
185 - libcoro did not take into account the trampoline on amd64,
186 when 'l'inux method was used.
187
188 1.31 Tue Aug 30 23:31:33 CEST 2005
189 - some portability fixes/workarounds.
190
191 1.3 Sat Aug 20 03:08:56 CEST 2005
192 - no code changes. module seems to work fine.
193 - improve Coro::State docs, remove reference to nonexisting
194 Coro::State::flush method.
195 - no longer autodetect windows, present it as an option instead.
196
197 1.2 Mon May 16 02:00:55 CEST 2005
198 - included libcoro.c earlier in State.xs, might improve portability.
199 - use a faster and possibly more stable Coro::Cont implementation.
200 - accept x86_64 in addition to amd64 for optimized linux-amd64 support.
201 - fix bugs Coro::SemaphoreSet that could cause locks never to be freed.
202 - fix bugs in CoroAPI.h and document it in Coro::MakeMaker.
203
204 1.11 Thu Mar 3 18:00:52 CET 2005
205 - change of contact address.
206
207 1.1 Tue Feb 22 20:51:16 CET 2005
208 - support [l]inux method on amd64.
209 - allow some context switches while compiling/eval'ing.
210
211 1.0 Tue Aug 10 03:47:27 CEST 2004
212 - Event 0.89 fixes the bug again.
213 - fix the remaining(??) memleak. I didn't free the cache-AV for
214 padlists, so one AV per created anon-sub leaked.
215
216 0.97 Fri May 14 15:23:32 CEST 2004
217 - remove stupid gcc extension that was an experiment only anyway.
218
219 0.96 Thu May 13 18:09:29 CEST 2004
220 - tell people if they have yet another broken Event variant.
221 - made Coro to work _better_ with threads (it seems that, as long
222 as you use Coros in one thread only everything will work fine.
223 Looking at the perl source the problem might be missing locking
224 between Coro and some perl internal routines. That's not easily
225 fixable).
226 - (hopefully) got rid of the static xnext inside transfer.
227
228 0.95 Sun Feb 15 03:20:28 CET 2004
229 - removed Coro::State::flush, implemented a new and much
230 faster caching mechanism by attaching magic to the CV.
231 - a memleak with (real) closures remains.
232 - dramatically reduced size of stacks to 65536 (linux/x86), after
233 observing that even myhttpd never had more than a kilobyte
234 of stack in use (stack is still only physically allocated in
235 pagesize increments for systems suporting mmap).
236 - fix for a "cygwin-64" architecture added, proposed by Stefan Traby.
237 - fix for threaded perl.
238
239 0.9 Sun Nov 23 04:32:39 CET 2003
240 - fix a few very hard to track down but (of course) stupid
241 memory leaks.
242 - stringify version number to avoid locale problems :(.
243 - perl 5.9.0 does not have SvPADBUSY, reported by Scott Walters,
244 hopefully ignoring it "just works".
245
246 0.8 Wed Nov 5 19:38:40 CET 2003
247 - port to perl5.005_03, but only 5.8.x+ is supported!
248 - honor LocalAddr even without LocalPort in Coro::Socket.
249
250 0.7 Tue May 27 03:12:38 CEST 2003
251 - the version jump indicates some level of testing, not gobs
252 of new features.
253 - uh... I found the prompt function in ExtUtils::MakeMaker.
254 Highly correct stuff, that is...
255 - fixed(?) a bug with die's in coroutines causing "panic: top_env".
256 the fix is not well understood by the author, so beware :(.
257
258 0.652 Thu May 8 02:54:46 CEST 2003
259 - Applied patch by Slaven Rezic to set default to "s" on FreeBSD,
260 cause version 4 doesn't have ucontext.
261 - Benjamin Reed reported that setjmp works fine on darwin,
262 so preselect it.
263
264 0.651 Sat Mar 29 15:00:23 CET 2003
265 - fix a bug in Coro::Handle where some bytes could get lost
266 on reading, reported by jason@nichego.net.
267
268 0.65 Sun Mar 23 00:08:26 CET 2003
269 - added a README.linux-glibc.
270 - new module Coro::Select.
271 - also save/restore PL_comppad, fixes segfaults with 5.8.1.
272 (I never claimed that I know what I am doing ;).
273 - set default to setjmp/longjmp on non-x86-linux.
274
275 0.6 Thu Nov 21 11:09:06 CET 2002
276 - made lazy context switching the default.
277 - fixed the bug where SemaphoreSet::guard
278 was the same as timed_guard and timed_guard was missing.
279 - fix a memleak in Coro::Timer.
280 - reclassified context sharing as not experimental.
281
282 0.534 Sun Apr 14 03:05:12 CEST 2002
283 - fixed backspace => tab in header parsing (myhttpd).
284 - added eg/readline, for elmex.
285 - Coro::Event now calls ->start on first call instead of
286 ->again, which created wrong timeouts for the first ->next.
287 - fixed a bug where Coro::Socket returned a closed socket instead
288 of nothing on ECONNREFUSED and similar error conditions.
289
290 0.533 Mon Feb 18 18:49:40 CET 2002
291 - adapt to finally working Event-0.85.
292 - fixed buggy event initialization (trapped under windows, but how
293 could it possibly have worked anywhere?)
294
295 0.532 Wed Jan 16 02:45:32 CET 2002
296 - removed the reference to pp_entersub, might work on
297 (some) win32 perls now (testsuite works under cygwin,
298 without Event, which freezes).
299
300 0.531 Mon Dec 10 22:18:44 CET 2001
301 - Fixed a bug in SemaphoreSet::timed_down.
302
303 0.53 Tue Nov 27 21:11:13 CET 2001
304 - some tests for Event.
305 - slightly different internal architecture to get refcnt into the object
306 and not the reference. might fix a few bugs, certainly did introduce
307 new ones.
308 - Coro::Timer (independent of Event).
309 - new timed_wait functions for Coro::Signal, Semaphore, SemaphoreSet.
310
311 0.52 Tue Nov 6 21:36:18 CET 2001
312 - ported to cygwin (trivial).
313 patch by Gerrit P. Haase <gp@familiehaase.de>.
314 - small setjmp code fix by Sullivan.DanielJ@epamail.epa.gov.
315
316 0.51 Thu Nov 1 20:39:01 CET 2001
317 - terminate/cancel now work properly (otherwise termination
318 could cause a "next coroutine is not and contains not..."
319 error.
320 - added Coro::Socket::shutdown.
321 - Coro::Event::loop no is the same as Event::loop.
322 - implemented terminate with args + join.
323
324 0.5 Fri Sep 28 16:15:35 CEST 2001
325 - fixed "print" on a Coro::Handle. The print method worked.
326 - small tweaks (seem to reduce memory consumption a lot)
327 in various modules.
328 - splendid use of "no warnings" scattered throughout.
329 - added Coro::Handle::rbuf, fixed Coro::Handle::fh.
330
331 0.49 Sun Sep 16 02:42:45 CEST 2001
332 - changed some method calls to function calls for speed
333 inside Coro::Handle.
334 - make Coro::Handle use an array instead of a hash for
335 speed reasons.
336 - IRIX mystery solved: it's SGI's NT, after all: "standard, huh?".
337 sjlj and ucontext should now work.
338 - IRIX-specific port for libcoro.
339 - swapped order of accept results to match IO::Socket.
340 - changed getsock/peername to sock/peername to match IO::Socket.
341 - fixed a bug that caused segfault when returning to main task
342 under some circumstances.
343 - other bugfixes.
344
345 0.45 Sun Sep 2 02:54:01 CEST 2001
346 - new method Coro::Handle::timeout.
347 - corrected speling of set...name to get...name in Coro::Socket.
348 - Coro::Socket::accept now returns a Coro::Socket, not a Coro::Handle.
349 - Coro::Handle now supports fileno and FILENO.
350 - added eg/myhttpd, a web server.
351 - Coro::Socket now accepts numeric ports as well as "port(number)"
352 syntax.
353 - moved some scheduling primitives into xs code. more to come.
354 - new simple priority system.
355 - implemented Coro::Event using XS, almost four times faster!
356 - small memory corruption problem fixed (boy that was difficult).
357
358 0.13 Wed Aug 8 16:53:07 CEST 2001
359 - new method Coro::Handle::readline.
360 - added eg/lwp and Coro::Handle::autoflush, to make LWP work.
361 (see eg/lwp on how to make LWP non-blocking).
362 - renamed Coro::Socket::new_inet to new.
363 - added Coro::Util, some utility functions.
364 - die/eval now works better (still get annoying (but true ;)
365 "Callback called exit" messages).
366 - Coro::Handle now supports timeout, and Coro::Socket Timeout.
367 - much better Coro::Socket support.
368
369 0.12 Fri Jul 27 04:19:01 CEST 2001
370 - do not use mmap if neither MAP_ANON nor MAP_ANONYMOUS is defined.
371 - very experimental stack sharing algorithm. not 100% safe but
372 should work well in practise ;)
373 - added Coro::RWLock.
374 - Coro::Specific now works.
375
376 0.11 Tue Jul 24 22:49:21 CEST 2001
377 - added specialized hack for newer and older linux versions (fast).
378 - renamed Coro::Event::IO to Coro::Handle.
379 - new module Coro::Socket.
380
381 0.1 Tue Jul 24 01:47:53 CEST 2001
382 - release candidate 3. A rather new internal structure :(
383 - the great renaming: Damian Conway gave me a suitable replacement
384 for yield.
385 - added Coro/libcoro, a portable coroutine implementation for C
386 (not even perl-dependent!!!), which can be used by Coro::State.
387 - renamed SAVE_DEFSV (on xs-level only) to avoid symbol clash in
388 perl-5.6.
389 - new function Coro::Event::idle.
390 - the idle process is now overriden
391 by default in Coro::Event.
392 - Coro::Channel now enforces the size.
393 - canceling events now works in all cases.
394 - Coro state now include $_ and $@.
395 - yet another bug workaround that I do not really understand :(
396 - new module Coro::Event::IO (very undocumented) to do
397 non-blocking i/o.
398 - performance tuning.
399
400 0.08 Thu Jul 19 06:13:25 CEST 2001
401 - release candidate 2 (new functionality).
402 - add Coro::State::flush function.
403 - transfer now supports a flags value (mostly for speed ATM).
404 - might compile and work in the presence of threads now.
405 - continuations have a saner syntax.
406 - no more memleaks.
407
408 0.07 Tue Jul 17 17:40:18 CEST 2001
409 - release candidate 1 ;)
410 - slightly nicer code.
411 - fixed a scheduling bug in Coro::Event.
412
413 0.06 Tue Jul 17 04:23:24 CEST 2001
414 - ok, I found the showstopper - the same sub must not be
415 re-entered in two different coroutines, otherwise => crash. I
416 see no easy solution to this problem, except by walking the call
417 chaing and saving/restoring the cv's, which is what I do now.
418 - memory leaks still latent, especially at thread termination.
419 - Coro::Event now works (haha).
420
421 0.05 Sun Jul 15 17:32:20 CEST 2001
422 - fixed a few issues in Coro::Event.
423 - I forgot to include Coro::Event in 0.04 :(:(:(
424
425 0.04 Sun Jul 15 05:24:59 CEST 2001
426 - @_ is now properly localized.
427 - Coro::State is now easier subclassable.
428 - Coro::Cont now coroutine-aware.
429 - Coro::Specific is a low-overhead module to create
430 coroutine-specific vars.
431 - Coro::Event provides a simple interface to Event.
432
433 0.03 Fri Jul 13 14:51:52 CEST 2001
434 - transfer() now implemented in XS (beware).
435 - new module Coro::Cont for really faked continuations.
436 - big internal architecture changes: Coro::State is now
437 really low-level and can thus be used to implement other
438 interesting things, While "Coro::" implements a process-like
439 model. Still crude and subject to change.
440 - $_ and $@ are no longer being localized.
441
442 0.02 Tue Jul 10 01:38:17 CEST 2001
443 - implemented "async" attribute.
444 - $_ and $@ are now localized.
445 - added Coro::Channel.
446 - more testcases, still no docs.
447
448 0.01 Tue Jul 3 02:18:41 CEST 2001
449 - original version; copied from Convert::Scalar.
450
