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