TODO: better (earlier) error messages on broken transfer's

3.2  Fri Dec 22 05:07:09 CET 2006
        - improve portability to slightly older perls.
        - use cleaner coroutine destruction.
        - simplify configuration for users.
        - optionally (unrecommended) prefer perl functions over
          their coro replacements.

3.11 Tue Dec  5 13:11:24 CET 2006
        - fixed some bogus assert's, but as perl.h disables assert even
          without NDEBUG (thank you very much), not too many people should
          notice (that did include myself). Andreas König noticed, though :)
        - do not save/restore PL_sortcxix on >= 5.9.x, it doesn't seem to have
          it. Also noticed by Andreas König :)
        - save/restore tainted status.
        - verified to pass the testsuite on my 5.9.5.

3.1  Mon Dec  4 23:03:40 CET 2006
        - INCOMPATIBLE CHANGE: $/ is now per-coroutine (but slow).
        - incompatible change: transfer flags are now per-state.
        - give a better error message on deadlock.
        - document Coro::nready.
        - enhanced testsuite.

3.01 Sun Dec  3 23:47:42 CET 2006
        - forgot to include Coro::Timer.

3.0  Sun Dec  3 22:57:25 CET 2006
        - the "FINALLY COMPLETELY STABLE" release (coming soon:
          the "FAMOUS LAST WORDS" release).
        - implement a new stack sharing algorithm, which uses a stack
          pool (size currently hardcoded).
        - make stack sharing mandatory (it no longer uses a heuristic).
        - eval/die no longer cause weird problems under heavy use.
        - Coro::Event could cause livelocks if it was used but
          no Coro::Event watchers were used.
        - Coro::Event now uses asynccheck as prepare does not
          check for changed watchers.
        - Coro::Event allows multiple waiting coros and will wake up one
          per event.
        - Coro::Event should be cleaner and more efficient now.
        - new utility function Coro::unblock_sub.
        - document the sad fact that Event is no longer reentrant.
        - putting a coroutine into the ready queue twice could under
          some circumstances lead to stack corruption.
        - minor incompatibility: subclassing Coro::State is supported
          directly now without going through a _coro_state member.
        - state/coro switching is much faster now.
        - very minor optimisations and code/documentation cleanup.
        - avoid problems due to compiler inlining.
        - removed timers from Coro::Timer -> use AnyEvent instead.
        - replaced Coro::idle coroutine by (cleaner) idle handler.
        - updated to newest libcoro.
        - implement enhanced support for valgrind.
        - implement is_ready and return value for ready.
        - removed Coro::Cont, it was a misnomer (it's generators),
          and it was somewhat annoying to get it right. Will come back
          if somebody asks for it :)
        - many ->wait methods and Coro::Event could return
          spuriously without the event having happened.

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.

31	root	1.171	3.0 Sun Dec 3 22:57:25 CET 2006
32	root	1.163	- the "FINALLY COMPLETELY STABLE" release (coming soon:
33			the "FAMOUS LAST WORDS" release).
34	root	1.166	- implement a new stack sharing algorithm, which uses a stack
35			pool (size currently hardcoded).
36	root	1.155	- make stack sharing mandatory (it no longer uses a heuristic).
37	root	1.157	- eval/die no longer cause weird problems under heavy use.
38	root	1.152	- Coro::Event could cause livelocks if it was used but
39	root	1.161	no Coro::Event watchers were used.
40	root	1.167	- Coro::Event now uses asynccheck as prepare does not
41			check for changed watchers.
42	root	1.170	- Coro::Event allows multiple waiting coros and will wake up one
43			per event.
44	root	1.152	- Coro::Event should be cleaner and more efficient now.
45	root	1.165	- new utility function Coro::unblock_sub.
46	root	1.164	- document the sad fact that Event is no longer reentrant.
47	root	1.163	- putting a coroutine into the ready queue twice could under
48			some circumstances lead to stack corruption.
49	root	1.161	- minor incompatibility: subclassing Coro::State is supported
50			directly now without going through a _coro_state member.
51	root	1.156	- state/coro switching is much faster now.
52	root	1.154	- very minor optimisations and code/documentation cleanup.
53	root	1.153	- avoid problems due to compiler inlining.
54	root	1.154	- removed timers from Coro::Timer -> use AnyEvent instead.
55			- replaced Coro::idle coroutine by (cleaner) idle handler.
56	root	1.156	- updated to newest libcoro.
57	root	1.159	- implement enhanced support for valgrind.
58	root	1.162	- implement is_ready and return value for ready.
59	root	1.168	- removed Coro::Cont, it was a misnomer (it's generators),
60			and it was somewhat annoying to get it right. Will come back
61			if somebody asks for it :)
62	root	1.163	- many ->wait methods and Coro::Event could return
63			spuriously without the event having happened.
64	root	1.146
65	root	1.145	2.5 Tue Nov 7 12:22:33 CET 2006
66	root	1.143	- made Coro::Util, Coro::Select, Coro::Handle and Coro::Socket
67			use AnyEvent, moved them to Coro/.
68	root	1.140	- added Coro::LWP which contains all the uglyness required to
69			make LWP non-blocking.
70			- should work with perl 5.9.x now (Andreas König made me do it).
71	root	1.141	- fixed another bug in Coro::Select when the timeout was undef.
72	root	1.136	- reuse PL_start_env for all coros, saves some memory per coroutine.
73			- manage PL_top_env differently, hopefully to avoid panic: top_env.
74	root	1.137	- timeout argument was not properly used in Coro::Socket.
75			- allow limited forms of subclassing in Coro::Handle/Coro::Socket.
76	root	1.138	- emulate undocumented(!) functionality of IO::Socket required
77			by LWP(!!).
78			- updated eg/lwp to work with newer lwp's.
79	root	1.140	- remove "FATAL: uncaught exception" prefix. Coroutines that die
80			kill the whole process, just as exceptions in the main "coroutine"
81			did already.
82	root	1.135
83	root	1.134	2.1 Wed Nov 1 23:01:13 CET 2006
84			- fix a long-standing bug in Coro::Select where select with
85			zero timeout would instead change the current default filehandle.
86	root	1.132	- use a simpler and hopefully more robust way to clone padlists
87			(uses less memory and a perl function instead of our own).
88			- coro can now create a stack guard area on many architectures.
89	root	1.134	- Coro::AIO properly reexports additional functions from IO::AIO.
90	root	1.132	- updated libcoro with a workaround for OS X,
91	root	1.134	pach and testing by Michael Schwern.
92	root	1.130
93	root	1.129	2.0 Tue Oct 24 05:47:17 CEST 2006
94	root	1.128	- support additional aio requests in Coro::AIO.
95
96	root	1.129	1.9 (never properly released due to a glitch)
97
98	root	1.127	1.8 Thu Feb 2 00:59:06 CET 2006
99	root	1.125	- applied suggested patch by SAMV to avoid problems during stupid
100			mark & sweep gc run.
101	root	1.126	- applied patch by Scott Walters for 5.9.3 compatibility.
102	root	1.125
103	root	1.124	1.7 Tue Dec 27 01:41:58 CET 2005
104	root	1.123	- added Coro::AIO, a thin wrapper around IO::AIO.
105	root	1.122	- improved Makefile.PL explanations.
106
107	root	1.119	1.6 Mon Dec 12 21:30:05 CET 2005
108	root	1.117	- additionally save PM_curpm might fix as-of-yet
109	root	1.121	unseen problems with regex matches being attributed to the
110	root	1.117	wrong package.
111	root	1.118	- add t/10_bugs.t, which currently checks against imho broken
112			perls that use 0.26MB of stack space per Perl_magic_get
113	root	1.121	invocation (newer linuxes) as opposed to the 0.0002MB perl
114			normally uses.
115	root	1.120	- make stacksize configurable for the ultimate debian experience.
116	root	1.117
117	root	1.116	1.51 Mon Dec 12 18:48:36 CET 2005
118			- remove debugging warn() accidentally left in Coro::Select.
119
120	root	1.115	1.5 Tue Nov 29 13:32:44 CET 2005
121	root	1.114	- use Coro::Event inside Coro::Select to avoid spurious deadlocks.
122	root	1.115	- fix Coro::Select 'select'.
123			- strict'ify some modules.
124	root	1.112	- libcoro errornously restored the SIGUSR2 handler to SIGUSR1.
125	root	1.115	- use XSLoader in selected modules.
126			- remove some 5.6 compatibility cruft.
127	root	1.112
128	root	1.111	1.4 Tue Sep 6 00:11:05 CEST 2005
129			- libcoro did not take into account the trampoline on amd64,
130			when 'l'inux method was used.
131
132	root	1.110	1.31 Tue Aug 30 23:31:33 CEST 2005
133			- some portability fixes/workarounds.
134
135	root	1.107	1.3 Sat Aug 20 03:08:56 CEST 2005
136	root	1.108	- no code changes. module seems to work fine.
137	root	1.106	- improve Coro::State docs, remove reference to nonexisting
138			Coro::State::flush method.
139	root	1.107	- no longer autodetect windows, present it as an option instead.
140	root	1.106
141	root	1.105	1.2 Mon May 16 02:00:55 CEST 2005
142	root	1.100	- included libcoro.c earlier in State.xs, might improve portability.
143	root	1.101	- use a faster and possibly more stable Coro::Cont implementation.
144	root	1.102	- accept x86_64 in addition to amd64 for optimized linux-amd64 support.
145	root	1.104	- fix bugs Coro::SemaphoreSet that could cause locks never to be freed.
146	root	1.105	- fix bugs in CoroAPI.h and document it in Coro::MakeMaker.
147	root	1.100
148	root	1.99	1.11 Thu Mar 3 18:00:52 CET 2005
149			- change of contact address.
150
151	root	1.98	1.1 Tue Feb 22 20:51:16 CET 2005
152	root	1.97	- support [l]inux method on amd64.
153	root	1.109	- allow some context switches while compiling/eval'ing.
154	root	1.97
155	root	1.96	1.0 Tue Aug 10 03:47:27 CEST 2004
156	root	1.95	- Event 0.89 fixes the bug again.
157	root	1.96	- fix the remaining(??) memleak. I didn't free the cache-AV for
158			padlists, so one AV per created anon-sub leaked.
159	root	1.95
160	pcg	1.94	0.97 Fri May 14 15:23:32 CEST 2004
161			- remove stupid gcc extension that was an experiment only anyway.
162
163	pcg	1.93	0.96 Thu May 13 18:09:29 CEST 2004
164	root	1.103	- tell people if they have yet another broken Event variant.
165	pcg	1.91	- made Coro to work _better_ with threads (it seems that, as long
166			as you use Coros in one thread only everything will work fine.
167			Looking at the perl source the problem might be missing locking
168			between Coro and some perl internal routines. That's not easily
169			fixable).
170	pcg	1.92	- (hopefully) got rid of the static xnext inside transfer.
171	pcg	1.91
172	pcg	1.90	0.95 Sun Feb 15 03:20:28 CET 2004
173	pcg	1.86	- removed Coro::State::flush, implemented a new and much
174			faster caching mechanism by attaching magic to the CV.
175	pcg	1.87	- a memleak with (real) closures remains.
176	pcg	1.88	- dramatically reduced size of stacks to 65536 (linux/x86), after
177			observing that even myhttpd never had more than a kilobyte
178			of stack in use (stack is still only physically allocated in
179			pagesize increments for systems suporting mmap).
180	pcg	1.89	- fix for a "cygwin-64" architecture added, proposed by Stefan Traby.
181	pcg	1.90	- fix for threaded perl.
182	pcg	1.86
183	pcg	1.85	0.9 Sun Nov 23 04:32:39 CET 2003
184	pcg	1.84	- fix a few very hard to track down but (of course) stupid
185			memory leaks.
186			- stringify version number to avoid locale problems :(.
187	pcg	1.85	- perl 5.9.0 does not have SvPADBUSY, reported by Scott Walters,
188			hopefully ignoring it "just works".
189	pcg	1.84
190	pcg	1.83	0.8 Wed Nov 5 19:38:40 CET 2003
191			- port to perl5.005_03, but only 5.8.x+ is supported!
192	pcg	1.82	- honor LocalAddr even without LocalPort in Coro::Socket.
193
194	root	1.81	0.7 Tue May 27 03:12:38 CEST 2003
195			- the version jump indicates some level of testing, not gobs
196			of new features.
197	root	1.80	- uh... I found the prompt function in ExtUtils::MakeMaker.
198			Highly correct stuff, that is...
199	root	1.81	- fixed(?) a bug with die's in coroutines causing "panic: top_env".
200			the fix is not well understood by the author, so beware :(.
201	root	1.80
202	root	1.79	0.652 Thu May 8 02:54:46 CEST 2003
203	root	1.76	- Applied patch by Slaven Rezic to set default to "s" on FreeBSD,
204	root	1.78	cause version 4 doesn't have ucontext.
205	root	1.77	- Benjamin Reed reported that setjmp works fine on darwin,
206			so preselect it.
207	root	1.76
208	root	1.75	0.651 Sat Mar 29 15:00:23 CET 2003
209			- fix a bug in Coro::Handle where some bytes could get lost
210			on reading, reported by jason@nichego.net.
211	root	1.74
212	root	1.73	0.65 Sun Mar 23 00:08:26 CET 2003
213	root	1.72	- added a README.linux-glibc.
214			- new module Coro::Select.
215			- also save/restore PL_comppad, fixes segfaults with 5.8.1.
216			(I never claimed that I know what I am doing ;).
217	root	1.73	- set default to setjmp/longjmp on non-x86-linux.
218	root	1.72
219	root	1.71	0.6 Thu Nov 21 11:09:06 CET 2002
220			- made lazy context switching the default.
221			- fixed the bug where SemaphoreSet::guard
222			was the same as timed_guard and timed_guard was missing.
223			- fix a memleak in Coro::Timer.
224			- reclassified context sharing as not experimental.
225
226	root	1.70	0.534 Sun Apr 14 03:05:12 CEST 2002
227	root	1.69	- fixed backspace => tab in header parsing (myhttpd).
228	root	1.70	- added eg/readline, for elmex.
229			- Coro::Event now calls ->start on first call instead of
230			->again, which created wrong timeouts for the first ->next.
231			- fixed a bug where Coro::Socket returned a closed socket instead
232			of nothing on ECONNREFUSED and similar error conditions.
233	root	1.69
234	root	1.68	0.533 Mon Feb 18 18:49:40 CET 2002
235			- adapt to finally working Event-0.85.
236			- fixed buggy event initialization (trapped under windows, but how
237			could it possibly have worked anywhere?)
238
239	root	1.67	0.532 Wed Jan 16 02:45:32 CET 2002
240	root	1.66	- removed the reference to pp_entersub, might work on
241			(some) win32 perls now (testsuite works under cygwin,
242			without Event, which freezes).
243	root	1.65
244	root	1.64	0.531 Mon Dec 10 22:18:44 CET 2001
245	root	1.63	- Fixed a bug in SemaphoreSet::timed_down.
246
247	root	1.64	0.53 Tue Nov 27 21:11:13 CET 2001
248	root	1.60	- some tests for Event.
249	root	1.61	- slightly different internal architecture to get refcnt into the object
250			and not the reference. might fix a few bugs, certainly did introduce
251			new ones.
252			- Coro::Timer (independent of Event).
253	root	1.62	- new timed_wait functions for Coro::Signal, Semaphore, SemaphoreSet.
254	root	1.60
255	root	1.64	0.52 Tue Nov 6 21:36:18 CET 2001
256	root	1.58	- ported to cygwin (trivial).
257			patch by Gerrit P. Haase <gp@familiehaase.de>.
258			- small setjmp code fix by Sullivan.DanielJ@epamail.epa.gov.
259
260	root	1.64	0.51 Thu Nov 1 20:39:01 CET 2001
261	root	1.54	- terminate/cancel now work properly (otherwise termination
262			could cause a "next coroutine is not and contains not..."
263			error.
264	root	1.55	- added Coro::Socket::shutdown.
265	root	1.56	- Coro::Event::loop no is the same as Event::loop.
266			- implemented terminate with args + join.
267	root	1.54
268	root	1.64	0.5 Fri Sep 28 16:15:35 CEST 2001
269	root	1.53	- fixed "print" on a Coro::Handle. The print method worked.
270	root	1.50	- small tweaks (seem to reduce memory consumption a lot)
271			in various modules.
272			- splendid use of "no warnings" scattered throughout.
273	root	1.52	- added Coro::Handle::rbuf, fixed Coro::Handle::fh.
274	root	1.48
275	root	1.47	0.49 Sun Sep 16 02:42:45 CEST 2001
276	root	1.43	- changed some method calls to function calls for speed
277			inside Coro::Handle.
278	root	1.44	- make Coro::Handle use an array instead of a hash for
279			speed reasons.
280			- IRIX mystery solved: it's SGI's NT, after all: "standard, huh?".
281			sjlj and ucontext should now work.
282			- IRIX-specific port for libcoro.
283	root	1.45	- swapped order of accept results to match IO::Socket.
284	root	1.46	- changed getsock/peername to sock/peername to match IO::Socket.
285			- fixed a bug that caused segfault when returning to main task
286			under some circumstances.
287			- other bugfixes.
288	root	1.43
289	root	1.42	0.45 Sun Sep 2 02:54:01 CEST 2001
290	root	1.36	- new method Coro::Handle::timeout.
291			- corrected speling of set...name to get...name in Coro::Socket.
292			- Coro::Socket::accept now returns a Coro::Socket, not a Coro::Handle.
293			- Coro::Handle now supports fileno and FILENO.
294			- added eg/myhttpd, a web server.
295	root	1.37	- Coro::Socket now accepts numeric ports as well as "port(number)"
296			syntax.
297	root	1.38	- moved some scheduling primitives into xs code. more to come.
298	root	1.39	- new simple priority system.
299	root	1.40	- implemented Coro::Event using XS, almost four times faster!
300	root	1.41	- small memory corruption problem fixed (boy that was difficult).
301	root	1.36
302	root	1.35	0.13 Wed Aug 8 16:53:07 CEST 2001
303	root	1.31	- new method Coro::Handle::readline.
304	root	1.34	- added eg/lwp and Coro::Handle::autoflush, to make LWP work.
305			(see eg/lwp on how to make LWP non-blocking).
306	root	1.31	- renamed Coro::Socket::new_inet to new.
307	root	1.32	- added Coro::Util, some utility functions.
308	root	1.33	- die/eval now works better (still get annoying (but true ;)
309			"Callback called exit" messages).
310	root	1.34	- Coro::Handle now supports timeout, and Coro::Socket Timeout.
311			- much better Coro::Socket support.
312	root	1.31
313			0.12 Fri Jul 27 04:19:01 CEST 2001
314	root	1.29	- do not use mmap if neither MAP_ANON nor MAP_ANONYMOUS is defined.
315	root	1.34	- very experimental stack sharing algorithm. not 100% safe but
316	root	1.28	should work well in practise ;)
317	root	1.30	- added Coro::RWLock.
318	root	1.31	- Coro::Specific now works.
319	root	1.28
320			0.11 Tue Jul 24 22:49:21 CEST 2001

323			- new module Coro::Socket.
324
325	root	1.26	0.1 Tue Jul 24 01:47:53 CEST 2001
326	root	1.23	- release candidate 3. A rather new internal structure :(
327	root	1.24	- the great renaming: Damian Conway gave me a suitable replacement
328			for yield.
329	root	1.23	- added Coro/libcoro, a portable coroutine implementation for C
330	root	1.22	(not even perl-dependent!!!), which can be used by Coro::State.
331	root	1.20	- renamed SAVE_DEFSV (on xs-level only) to avoid symbol clash in
332			perl-5.6.
333	root	1.16	- new function Coro::Event::idle.
334			- the idle process is now overriden
335			by default in Coro::Event.
336	root	1.17	- Coro::Channel now enforces the size.
337	root	1.18	- canceling events now works in all cases.
338	root	1.19	- Coro state now include $_ and $@.
339			- yet another bug workaround that I do not really understand :(
340	root	1.21	- new module Coro::Event::IO (very undocumented) to do
341			non-blocking i/o.
342	root	1.25	- performance tuning.
343	root	1.16
344	root	1.15	0.08 Thu Jul 19 06:13:25 CEST 2001
345	root	1.14	- release candidate 2 (new functionality).
346	root	1.13	- add Coro::State::flush function.
347			- transfer now supports a flags value (mostly for speed ATM).
348			- might compile and work in the presence of threads now.
349	root	1.14	- continuations have a saner syntax.
350	root	1.19	- no more memleaks.
351	root	1.13
352	root	1.12	0.07 Tue Jul 17 17:40:18 CEST 2001
353			- release candidate 1 ;)
354			- slightly nicer code.
355			- fixed a scheduling bug in Coro::Event.
356
357	root	1.11	0.06 Tue Jul 17 04:23:24 CEST 2001
358			- ok, I found the showstopper - the same sub must not be
359	root	1.9	re-entered in two different coroutines, otherwise => crash. I
360			see no easy solution to this problem, except by walking the call
361			chaing and saving/restoring the cv's, which is what I do now.
362	root	1.11	- memory leaks still latent, especially at thread termination.
363			- Coro::Event now works (haha).
364	root	1.9
365	root	1.8	0.05 Sun Jul 15 17:32:20 CEST 2001
366			- fixed a few issues in Coro::Event.
367			- I forgot to include Coro::Event in 0.04 :(:(:(
368
369	root	1.7	0.04 Sun Jul 15 05:24:59 CEST 2001
370	root	1.5	- @_ is now properly localized.
371	root	1.4	- Coro::State is now easier subclassable.
372			- Coro::Cont now coroutine-aware.
373			- Coro::Specific is a low-overhead module to create
374			coroutine-specific vars.
375	root	1.6	- Coro::Event provides a simple interface to Event.
376	root	1.4
377	root	1.3	0.03 Fri Jul 13 14:51:52 CEST 2001
378	root	1.4	- transfer() now implemented in XS (beware).
379			- new module Coro::Cont for really faked continuations.
380			- big internal architecture changes: Coro::State is now
381	root	1.3	really low-level and can thus be used to implement other
382	root	1.4	interesting things, While "Coro::" implements a process-like
383			model. Still crude and subject to change.
384	root	1.3	- $_ and $@ are no longer being localized.
385
386	root	1.2	0.02 Tue Jul 10 01:38:17 CEST 2001
387			- implemented "async" attribute.
388			- $_ and $@ are now localized.
389			- added Coro::Channel.
