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