[ViewVC] Annotation of: cvs/Coro/Changes

Revision history for Perl extension Coro.

        - avoid deadlock in Coro::Event's idle process when it is called
          early with no active watchers.
        - minor documentation cleanup.

2.5  Tue Nov  7 12:22:33 CET 2006
        - made Coro::Util, Coro::Select, Coro::Handle and Coro::Socket
          use AnyEvent, moved them to Coro/.
        - added Coro::LWP which contains all the uglyness required to
          make LWP non-blocking.
        - should work with perl 5.9.x now (Andreas König made me do it).
        - fixed another bug in Coro::Select when the timeout was undef.
        - reuse PL_start_env for all coros, saves some memory per coroutine.
        - manage PL_top_env differently, hopefully to avoid panic: top_env.
        - timeout argument was not properly used in Coro::Socket.
        - allow limited forms of subclassing in Coro::Handle/Coro::Socket.
        - emulate undocumented(!) functionality of IO::Socket required
          by LWP(!!).
        - updated eg/lwp to work with newer lwp's.
        - remove "FATAL: uncaught exception" prefix. Coroutines that die
          kill the whole process, just as exceptions in the main "coroutine"
          did already.

2.1  Wed Nov  1 23:01:13 CET 2006
        - fix a long-standing bug in Coro::Select where select with
          zero timeout would instead change the current default filehandle.
        - use a simpler and hopefully more robust way to clone padlists
          (uses less memory and a perl function instead of our own).
        - coro can now create a stack guard area on many architectures.
        - Coro::AIO properly reexports additional functions from IO::AIO.
        - updated libcoro with a workaround for OS X,
          pach and testing by Michael Schwern.

2.0  Tue Oct 24 05:47:17 CEST 2006
        - support additional aio requests in Coro::AIO.

1.9  (never properly released due to a glitch)

1.8  Thu Feb  2 00:59:06 CET 2006
        - applied suggested patch by SAMV to avoid problems during stupid
          mark & sweep gc run.
        - applied patch by Scott Walters for 5.9.3 compatibility.

1.7  Tue Dec 27 01:41:58 CET 2005
        - added Coro::AIO, a thin wrapper around IO::AIO.
        - improved Makefile.PL explanations.

1.6  Mon Dec 12 21:30:05 CET 2005
        - additionally save PM_curpm might fix as-of-yet
          unseen problems with regex matches being attributed to the
          wrong package.
        - add t/10_bugs.t, which currently checks against imho broken
          perls that use 0.26MB of stack space per Perl_magic_get
          invocation (newer linuxes) as opposed to the 0.0002MB perl
          normally uses.
        - make stacksize configurable for the ultimate debian experience.

1.51 Mon Dec 12 18:48:36 CET 2005
        - remove debugging warn() accidentally left in Coro::Select.

1.5  Tue Nov 29 13:32:44 CET 2005
        - use Coro::Event inside Coro::Select to avoid spurious deadlocks.
        - fix Coro::Select 'select'.
        - strict'ify some modules.
        - libcoro errornously restored the SIGUSR2 handler to SIGUSR1.
        - use XSLoader in selected modules.
        - remove some 5.6 compatibility cruft.

1.4  Tue Sep  6 00:11:05 CEST 2005
        - libcoro did not take into account the trampoline on amd64,
          when 'l'inux method was used.

1.31 Tue Aug 30 23:31:33 CEST 2005
        - some portability fixes/workarounds.

1.3  Sat Aug 20 03:08:56 CEST 2005
        - no code changes. module seems to work fine.
        - improve Coro::State docs, remove reference to nonexisting
          Coro::State::flush method.
        - no longer autodetect windows, present it as an option instead.

1.2  Mon May 16 02:00:55 CEST 2005
        - included libcoro.c earlier in State.xs, might improve portability.
        - use a faster and possibly more stable Coro::Cont implementation.
        - accept x86_64 in addition to amd64 for optimized linux-amd64 support.
        - fix bugs Coro::SemaphoreSet that could cause locks never to be freed.
        - fix bugs in CoroAPI.h and document it in Coro::MakeMaker.

1.11 Thu Mar  3 18:00:52 CET 2005
        - change of contact address.

1.1 Tue Feb 22 20:51:16 CET 2005
        - support [l]inux method on amd64.
        - allow some context switches while compiling/eval'ing.

1.0  Tue Aug 10 03:47:27 CEST 2004
        - Event 0.89 fixes the bug again.
        - fix the remaining(??) memleak. I didn't free the cache-AV for
          padlists, so one AV per created anon-sub leaked.

0.97 Fri May 14 15:23:32 CEST 2004
        - remove stupid gcc extension that was an experiment only anyway.

0.96 Thu May 13 18:09:29 CEST 2004
        - tell people if they have yet another broken Event variant.
        - made Coro to work _better_ with threads (it seems that, as long
          as you use Coros in one thread only everything will work fine.
          Looking at the perl source the problem might be missing locking
          between Coro and some perl internal routines. That's not easily
          fixable).
        - (hopefully) got rid of the static xnext inside transfer.

0.95 Sun Feb 15 03:20:28 CET 2004
        - removed Coro::State::flush, implemented a new and much
          faster caching mechanism by attaching magic to the CV.
        - a memleak with (real) closures remains.
        - dramatically reduced size of stacks to 65536 (linux/x86), after
          observing that even myhttpd never had more than a kilobyte
          of stack in use (stack is still only physically allocated in
          pagesize increments for systems suporting mmap).
        - fix for a "cygwin-64" architecture added, proposed by Stefan Traby.
        - fix for threaded perl.

0.9  Sun Nov 23 04:32:39 CET 2003
        - fix a few very hard to track down but (of course) stupid
          memory leaks.
        - stringify version number to avoid locale problems :(.
        - perl 5.9.0 does not have SvPADBUSY, reported by Scott Walters,
          hopefully ignoring it "just works".

0.8   Wed Nov  5 19:38:40 CET 2003
        - port to perl5.005_03, but only 5.8.x+ is supported!
        - honor LocalAddr even without LocalPort in Coro::Socket.

0.7   Tue May 27 03:12:38 CEST 2003
        - the version jump indicates some level of testing, not gobs
          of new features.
        - uh... I found the prompt function in ExtUtils::MakeMaker.
          Highly correct stuff, that is...
        - fixed(?) a bug with die's in coroutines causing "panic: top_env".
          the fix is not well understood by the author, so beware :(.

0.652 Thu May  8 02:54:46 CEST 2003
        - Applied patch by Slaven Rezic to set default to "s" on FreeBSD,
          cause version 4 doesn't have ucontext.
        - Benjamin Reed reported that setjmp works fine on darwin,
          so preselect it.

0.651 Sat Mar 29 15:00:23 CET 2003
        - fix a bug in Coro::Handle where some bytes could get lost
          on reading, reported by jason@nichego.net.

0.65  Sun Mar 23 00:08:26 CET 2003
        - added a README.linux-glibc.
        - new module Coro::Select.
        - also save/restore PL_comppad, fixes segfaults with 5.8.1.
          (I never claimed that I know what I am doing ;).
        - set default to setjmp/longjmp on non-x86-linux.

0.6   Thu Nov 21 11:09:06 CET 2002
        - made lazy context switching the default.
        - fixed the bug where SemaphoreSet::guard
          was the same as timed_guard and timed_guard was missing.
        - fix a memleak in Coro::Timer.
        - reclassified context sharing as not experimental.

0.534 Sun Apr 14 03:05:12 CEST 2002
        - fixed backspace => tab in header parsing (myhttpd).
        - added eg/readline, for elmex.
        - Coro::Event now calls ->start on first call instead of
          ->again, which created wrong timeouts for the first ->next.
        - fixed a bug where Coro::Socket returned a closed socket instead
          of nothing on ECONNREFUSED and similar error conditions.

0.533 Mon Feb 18 18:49:40 CET 2002
        - adapt to finally working Event-0.85.
        - fixed buggy event initialization (trapped under windows, but how
          could it possibly have worked anywhere?)

0.532 Wed Jan 16 02:45:32 CET 2002
        - removed the reference to pp_entersub, might work on
          (some) win32 perls now (testsuite works under cygwin,
          without Event, which freezes).

0.531 Mon Dec 10 22:18:44 CET 2001
        - Fixed a bug in SemaphoreSet::timed_down.

0.53  Tue Nov 27 21:11:13 CET 2001
        - some tests for Event.
        - slightly different internal architecture to get refcnt into the object
          and not the reference. might fix a few bugs, certainly did introduce
          new ones.
        - Coro::Timer (independent of Event).
        - new timed_wait functions for Coro::Signal, Semaphore, SemaphoreSet.

0.52  Tue Nov  6 21:36:18 CET 2001
        - ported to cygwin (trivial).
          patch by Gerrit P. Haase <gp@familiehaase.de>.
        - small setjmp code fix by Sullivan.DanielJ@epamail.epa.gov.

0.51  Thu Nov  1 20:39:01 CET 2001
        - terminate/cancel now work properly (otherwise termination
          could cause a "next coroutine is not and contains not..."
          error.
        - added Coro::Socket::shutdown.
        - Coro::Event::loop no is the same as Event::loop.
        - implemented terminate with args + join.

0.5   Fri Sep 28 16:15:35 CEST 2001
        - fixed "print" on a Coro::Handle. The print method worked.
        - small tweaks (seem to reduce memory consumption a lot)
          in various modules.
        - splendid use of "no warnings" scattered throughout.
        - added Coro::Handle::rbuf, fixed Coro::Handle::fh.

0.49  Sun Sep 16 02:42:45 CEST 2001
        - changed some method calls to function calls for speed
          inside Coro::Handle.
        - make Coro::Handle use an array instead of a hash for
          speed reasons.
        - IRIX mystery solved: it's SGI's NT, after all: "standard, huh?".
          sjlj and ucontext should now work.
        - IRIX-specific port for libcoro.
        - swapped order of accept results to match IO::Socket.
        - changed getsock/peername to sock/peername to match IO::Socket.
        - fixed a bug that caused segfault when returning to main task
          under some circumstances.
        - other bugfixes.

0.45  Sun Sep  2 02:54:01 CEST 2001
        - new method Coro::Handle::timeout.
        - corrected speling of set...name to get...name in Coro::Socket.
        - Coro::Socket::accept now returns a Coro::Socket, not a Coro::Handle.
        - Coro::Handle now supports fileno and FILENO.
        - added eg/myhttpd, a web server.
        - Coro::Socket now accepts numeric ports as well as "port(number)"
          syntax.
        - moved some scheduling primitives into xs code. more to come.
        - new simple priority system.
        - implemented Coro::Event using XS, almost four times faster!
        - small memory corruption problem fixed (boy that was difficult).

0.13  Wed Aug  8 16:53:07 CEST 2001
        - new method Coro::Handle::readline.
        - added eg/lwp and Coro::Handle::autoflush, to make LWP work.
          (see eg/lwp on how to make LWP non-blocking).
        - renamed Coro::Socket::new_inet to new.
        - added Coro::Util, some utility functions.
        - die/eval now works better (still get annoying (but true ;)
          "Callback called exit" messages).
        - Coro::Handle now supports timeout, and Coro::Socket Timeout.
        - much better Coro::Socket support.

0.12  Fri Jul 27 04:19:01 CEST 2001
        - do not use mmap if neither MAP_ANON nor MAP_ANONYMOUS is defined.
        - very experimental stack sharing algorithm. not 100% safe but
          should work well in practise ;)
        - added Coro::RWLock.
        - Coro::Specific now works.

0.11  Tue Jul 24 22:49:21 CEST 2001
        - added specialized hack for newer and older linux versions (fast).
        - renamed Coro::Event::IO to Coro::Handle.
        - new module Coro::Socket.

0.1   Tue Jul 24 01:47:53 CEST 2001
        - release candidate 3. A rather new internal structure :(
        - the great renaming: Damian Conway gave me a suitable replacement
          for yield.
        - added Coro/libcoro, a portable coroutine implementation for C
          (not even perl-dependent!!!), which can be used by Coro::State.
        - renamed SAVE_DEFSV (on xs-level only) to avoid symbol clash in
          perl-5.6.
        - new function Coro::Event::idle.
        - the idle process is now overriden
          by default in Coro::Event.
        - Coro::Channel now enforces the size.
        - canceling events now works in all cases.
        - Coro state now include $_ and $@.
        - yet another bug workaround that I do not really understand :(
        - new module Coro::Event::IO (very undocumented) to do
          non-blocking i/o.
        - performance tuning.

0.08  Thu Jul 19 06:13:25 CEST 2001
        - release candidate 2 (new functionality).
        - add Coro::State::flush function.
        - transfer now supports a flags value (mostly for speed ATM).
        - might compile and work in the presence of threads now.
        - continuations have a saner syntax.
        - no more memleaks.

0.07  Tue Jul 17 17:40:18 CEST 2001
        - release candidate 1 ;)
        - slightly nicer code.
        - fixed a scheduling bug in Coro::Event.

0.06  Tue Jul 17 04:23:24 CEST 2001
        - ok, I found the showstopper - the same sub must not be
          re-entered in two different coroutines, otherwise => crash. I
          see no easy solution to this problem, except by walking the call
          chaing and saving/restoring the cv's, which is what I do now.
        - memory leaks still latent, especially at thread termination.
        - Coro::Event now works (haha).

0.05  Sun Jul 15 17:32:20 CEST 2001
        - fixed a few issues in Coro::Event.
        - I forgot to include Coro::Event in 0.04 :(:(:(

0.04  Sun Jul 15 05:24:59 CEST 2001
        - @_ is now properly localized.
        - Coro::State is now easier subclassable.
        - Coro::Cont now coroutine-aware.
        - Coro::Specific is a low-overhead module to create
          coroutine-specific vars.
        - Coro::Event provides a simple interface to Event.

0.03  Fri Jul 13 14:51:52 CEST 2001
        - transfer() now implemented in XS (beware).
        - new module Coro::Cont for really faked continuations.
        - big internal architecture changes: Coro::State is now
          really low-level and can thus be used to implement other
          interesting things, While "Coro::" implements a process-like
          model. Still crude and subject to change.
        - $_ and $@ are no longer being localized.

0.02  Tue Jul 10 01:38:17 CEST 2001
        - implemented "async" attribute.
        - $_ and $@ are now localized.
        - added Coro::Channel.
        - more testcases, still no docs.

0.01  Tue Jul  3 02:18:41 CEST 2001
        - original version; copied from Convert::Scalar.

79	root	1.106	- improve Coro::State docs, remove reference to nonexisting
80			Coro::State::flush method.
81	root	1.107	- no longer autodetect windows, present it as an option instead.
82	root	1.106
83	root	1.105	1.2 Mon May 16 02:00:55 CEST 2005
84	root	1.100	- included libcoro.c earlier in State.xs, might improve portability.
85	root	1.101	- use a faster and possibly more stable Coro::Cont implementation.
86	root	1.102	- accept x86_64 in addition to amd64 for optimized linux-amd64 support.
87	root	1.104	- fix bugs Coro::SemaphoreSet that could cause locks never to be freed.
88	root	1.105	- fix bugs in CoroAPI.h and document it in Coro::MakeMaker.
89	root	1.100
90	root	1.99	1.11 Thu Mar 3 18:00:52 CET 2005
91			- change of contact address.
92
93	root	1.98	1.1 Tue Feb 22 20:51:16 CET 2005
94	root	1.97	- support [l]inux method on amd64.
95	root	1.109	- allow some context switches while compiling/eval'ing.
96	root	1.97
97	root	1.96	1.0 Tue Aug 10 03:47:27 CEST 2004
98	root	1.95	- Event 0.89 fixes the bug again.
99	root	1.96	- fix the remaining(??) memleak. I didn't free the cache-AV for
100			padlists, so one AV per created anon-sub leaked.
101	root	1.95
102	pcg	1.94	0.97 Fri May 14 15:23:32 CEST 2004
103			- remove stupid gcc extension that was an experiment only anyway.
104
105	pcg	1.93	0.96 Thu May 13 18:09:29 CEST 2004
106	root	1.103	- tell people if they have yet another broken Event variant.
107	pcg	1.91	- made Coro to work _better_ with threads (it seems that, as long
108			as you use Coros in one thread only everything will work fine.
109			Looking at the perl source the problem might be missing locking
110			between Coro and some perl internal routines. That's not easily
111			fixable).
112	pcg	1.92	- (hopefully) got rid of the static xnext inside transfer.
113	pcg	1.91
114	pcg	1.90	0.95 Sun Feb 15 03:20:28 CET 2004
115	pcg	1.86	- removed Coro::State::flush, implemented a new and much
116			faster caching mechanism by attaching magic to the CV.
117	pcg	1.87	- a memleak with (real) closures remains.
118	pcg	1.88	- dramatically reduced size of stacks to 65536 (linux/x86), after
119			observing that even myhttpd never had more than a kilobyte
120			of stack in use (stack is still only physically allocated in
121			pagesize increments for systems suporting mmap).
122	pcg	1.89	- fix for a "cygwin-64" architecture added, proposed by Stefan Traby.
123	pcg	1.90	- fix for threaded perl.
124	pcg	1.86
125	pcg	1.85	0.9 Sun Nov 23 04:32:39 CET 2003
126	pcg	1.84	- fix a few very hard to track down but (of course) stupid
127			memory leaks.
128			- stringify version number to avoid locale problems :(.
129	pcg	1.85	- perl 5.9.0 does not have SvPADBUSY, reported by Scott Walters,
130			hopefully ignoring it "just works".
131	pcg	1.84
132	pcg	1.83	0.8 Wed Nov 5 19:38:40 CET 2003
133			- port to perl5.005_03, but only 5.8.x+ is supported!
134	pcg	1.82	- honor LocalAddr even without LocalPort in Coro::Socket.
135
136	root	1.81	0.7 Tue May 27 03:12:38 CEST 2003
137			- the version jump indicates some level of testing, not gobs
138			of new features.
139	root	1.80	- uh... I found the prompt function in ExtUtils::MakeMaker.
140			Highly correct stuff, that is...
141	root	1.81	- fixed(?) a bug with die's in coroutines causing "panic: top_env".
142			the fix is not well understood by the author, so beware :(.
143	root	1.80
144	root	1.79	0.652 Thu May 8 02:54:46 CEST 2003
145	root	1.76	- Applied patch by Slaven Rezic to set default to "s" on FreeBSD,
146	root	1.78	cause version 4 doesn't have ucontext.
147	root	1.77	- Benjamin Reed reported that setjmp works fine on darwin,
148			so preselect it.
149	root	1.76
150	root	1.75	0.651 Sat Mar 29 15:00:23 CET 2003
151			- fix a bug in Coro::Handle where some bytes could get lost
152			on reading, reported by jason@nichego.net.
153	root	1.74
154	root	1.73	0.65 Sun Mar 23 00:08:26 CET 2003
155	root	1.72	- added a README.linux-glibc.
156			- new module Coro::Select.
157			- also save/restore PL_comppad, fixes segfaults with 5.8.1.
158			(I never claimed that I know what I am doing ;).
159	root	1.73	- set default to setjmp/longjmp on non-x86-linux.
160	root	1.72
161	root	1.71	0.6 Thu Nov 21 11:09:06 CET 2002
162			- made lazy context switching the default.
163			- fixed the bug where SemaphoreSet::guard
164			was the same as timed_guard and timed_guard was missing.
165			- fix a memleak in Coro::Timer.
166			- reclassified context sharing as not experimental.
167
168	root	1.70	0.534 Sun Apr 14 03:05:12 CEST 2002
169	root	1.69	- fixed backspace => tab in header parsing (myhttpd).
170	root	1.70	- added eg/readline, for elmex.
171			- Coro::Event now calls ->start on first call instead of
172			->again, which created wrong timeouts for the first ->next.
173			- fixed a bug where Coro::Socket returned a closed socket instead
174			of nothing on ECONNREFUSED and similar error conditions.
175	root	1.69
176	root	1.68	0.533 Mon Feb 18 18:49:40 CET 2002
177			- adapt to finally working Event-0.85.
178			- fixed buggy event initialization (trapped under windows, but how
179			could it possibly have worked anywhere?)
180
181	root	1.67	0.532 Wed Jan 16 02:45:32 CET 2002
182	root	1.66	- removed the reference to pp_entersub, might work on
183			(some) win32 perls now (testsuite works under cygwin,
184			without Event, which freezes).
185	root	1.65
186	root	1.64	0.531 Mon Dec 10 22:18:44 CET 2001
187	root	1.63	- Fixed a bug in SemaphoreSet::timed_down.
188
189	root	1.64	0.53 Tue Nov 27 21:11:13 CET 2001
190	root	1.60	- some tests for Event.
191	root	1.61	- slightly different internal architecture to get refcnt into the object
192			and not the reference. might fix a few bugs, certainly did introduce
193			new ones.
194			- Coro::Timer (independent of Event).
195	root	1.62	- new timed_wait functions for Coro::Signal, Semaphore, SemaphoreSet.
196	root	1.60
197	root	1.64	0.52 Tue Nov 6 21:36:18 CET 2001
198	root	1.58	- ported to cygwin (trivial).
199			patch by Gerrit P. Haase <gp@familiehaase.de>.
200			- small setjmp code fix by Sullivan.DanielJ@epamail.epa.gov.
201
202	root	1.64	0.51 Thu Nov 1 20:39:01 CET 2001
203	root	1.54	- terminate/cancel now work properly (otherwise termination
204			could cause a "next coroutine is not and contains not..."
205			error.
206	root	1.55	- added Coro::Socket::shutdown.
207	root	1.56	- Coro::Event::loop no is the same as Event::loop.
208			- implemented terminate with args + join.
209	root	1.54
210	root	1.64	0.5 Fri Sep 28 16:15:35 CEST 2001
211	root	1.53	- fixed "print" on a Coro::Handle. The print method worked.
212	root	1.50	- small tweaks (seem to reduce memory consumption a lot)
213			in various modules.
214			- splendid use of "no warnings" scattered throughout.
215	root	1.52	- added Coro::Handle::rbuf, fixed Coro::Handle::fh.
216	root	1.48
217	root	1.47	0.49 Sun Sep 16 02:42:45 CEST 2001
218	root	1.43	- changed some method calls to function calls for speed
219			inside Coro::Handle.
220	root	1.44	- make Coro::Handle use an array instead of a hash for
221			speed reasons.
222			- IRIX mystery solved: it's SGI's NT, after all: "standard, huh?".
223			sjlj and ucontext should now work.
224			- IRIX-specific port for libcoro.
225	root	1.45	- swapped order of accept results to match IO::Socket.
226	root	1.46	- changed getsock/peername to sock/peername to match IO::Socket.
227			- fixed a bug that caused segfault when returning to main task
228			under some circumstances.
229			- other bugfixes.
230	root	1.43
231	root	1.42	0.45 Sun Sep 2 02:54:01 CEST 2001
232	root	1.36	- new method Coro::Handle::timeout.
233			- corrected speling of set...name to get...name in Coro::Socket.
234			- Coro::Socket::accept now returns a Coro::Socket, not a Coro::Handle.
235			- Coro::Handle now supports fileno and FILENO.
236			- added eg/myhttpd, a web server.
237	root	1.37	- Coro::Socket now accepts numeric ports as well as "port(number)"
238			syntax.
239	root	1.38	- moved some scheduling primitives into xs code. more to come.
240	root	1.39	- new simple priority system.
241	root	1.40	- implemented Coro::Event using XS, almost four times faster!
242	root	1.41	- small memory corruption problem fixed (boy that was difficult).
243	root	1.36
244	root	1.35	0.13 Wed Aug 8 16:53:07 CEST 2001
245	root	1.31	- new method Coro::Handle::readline.
246	root	1.34	- added eg/lwp and Coro::Handle::autoflush, to make LWP work.
247			(see eg/lwp on how to make LWP non-blocking).
248	root	1.31	- renamed Coro::Socket::new_inet to new.
249	root	1.32	- added Coro::Util, some utility functions.
250	root	1.33	- die/eval now works better (still get annoying (but true ;)
251			"Callback called exit" messages).
252	root	1.34	- Coro::Handle now supports timeout, and Coro::Socket Timeout.
253			- much better Coro::Socket support.
254	root	1.31
255			0.12 Fri Jul 27 04:19:01 CEST 2001
256	root	1.29	- do not use mmap if neither MAP_ANON nor MAP_ANONYMOUS is defined.
257	root	1.34	- very experimental stack sharing algorithm. not 100% safe but
258	root	1.28	should work well in practise ;)
259	root	1.30	- added Coro::RWLock.
260	root	1.31	- Coro::Specific now works.
261	root	1.28
262			0.11 Tue Jul 24 22:49:21 CEST 2001
263	root	1.27	- added specialized hack for newer and older linux versions (fast).
264			- renamed Coro::Event::IO to Coro::Handle.
265			- new module Coro::Socket.
266
267	root	1.26	0.1 Tue Jul 24 01:47:53 CEST 2001
268	root	1.23	- release candidate 3. A rather new internal structure :(
269	root	1.24	- the great renaming: Damian Conway gave me a suitable replacement
270			for yield.
271	root	1.23	- added Coro/libcoro, a portable coroutine implementation for C
272	root	1.22	(not even perl-dependent!!!), which can be used by Coro::State.
273	root	1.20	- renamed SAVE_DEFSV (on xs-level only) to avoid symbol clash in
274			perl-5.6.
275	root	1.16	- new function Coro::Event::idle.
276			- the idle process is now overriden
277			by default in Coro::Event.
278	root	1.17	- Coro::Channel now enforces the size.
279	root	1.18	- canceling events now works in all cases.
280	root	1.19	- Coro state now include $_ and $@.
281			- yet another bug workaround that I do not really understand :(
282	root	1.21	- new module Coro::Event::IO (very undocumented) to do
283			non-blocking i/o.
284	root	1.25	- performance tuning.
285	root	1.16
286	root	1.15	0.08 Thu Jul 19 06:13:25 CEST 2001
287	root	1.14	- release candidate 2 (new functionality).
288	root	1.13	- add Coro::State::flush function.
289			- transfer now supports a flags value (mostly for speed ATM).
290			- might compile and work in the presence of threads now.
291	root	1.14	- continuations have a saner syntax.
292	root	1.19	- no more memleaks.
293	root	1.13
294	root	1.12	0.07 Tue Jul 17 17:40:18 CEST 2001
295			- release candidate 1 ;)
296			- slightly nicer code.
297			- fixed a scheduling bug in Coro::Event.
298
299	root	1.11	0.06 Tue Jul 17 04:23:24 CEST 2001
300			- ok, I found the showstopper - the same sub must not be
301	root	1.9	re-entered in two different coroutines, otherwise => crash. I
302			see no easy solution to this problem, except by walking the call
303			chaing and saving/restoring the cv's, which is what I do now.
304	root	1.11	- memory leaks still latent, especially at thread termination.
305			- Coro::Event now works (haha).
306	root	1.9
307	root	1.8	0.05 Sun Jul 15 17:32:20 CEST 2001
308			- fixed a few issues in Coro::Event.
309			- I forgot to include Coro::Event in 0.04 :(:(:(
310
311	root	1.7	0.04 Sun Jul 15 05:24:59 CEST 2001
312	root	1.5	- @_ is now properly localized.
313	root	1.4	- Coro::State is now easier subclassable.
314			- Coro::Cont now coroutine-aware.
315			- Coro::Specific is a low-overhead module to create
316			coroutine-specific vars.
317	root	1.6	- Coro::Event provides a simple interface to Event.
318	root	1.4
319	root	1.3	0.03 Fri Jul 13 14:51:52 CEST 2001
320	root	1.4	- transfer() now implemented in XS (beware).
321			- new module Coro::Cont for really faked continuations.
322			- big internal architecture changes: Coro::State is now
323	root	1.3	really low-level and can thus be used to implement other
324	root	1.4	interesting things, While "Coro::" implements a process-like
325			model. Still crude and subject to change.
326	root	1.3	- $_ and $@ are no longer being localized.
327
328	root	1.2	0.02 Tue Jul 10 01:38:17 CEST 2001
329			- implemented "async" attribute.
330			- $_ and $@ are now localized.
331			- added Coro::Channel.
332			- more testcases, still no docs.
333
334	root	1.1	0.01 Tue Jul 3 02:18:41 CEST 2001
335			- original version; copied from Convert::Scalar.
336
