Revision history for Perl extension Coro.

TODO: better (earlier) error messages on broken transfer's
TODO: destroy gets only called on cancel: fix(?)
TODO: fast reloads in cf cause segfaults (coro_state_free->destroy->crash)

3.4  Fri Jan 19 21:52:54 CET 2007
        - remove t/09_timer.t, as it isn't really testing much
          but was rather flaky in practise.
        - async_pool coro would keep arguments and callback alive until
          it was reused.
        - cancellation of a coroutine could cause spurious idle calls
          in cede_notself.

3.3  Sat Jan  6 03:45:00 CET 2007
        - implement $coro->on_destroy.
        - Coro::Event blocking semantics have been changed,
          documented and - hopefully - improved.
        - fix nice adding, not subtracting, from priority.
        - fix ->prio and api_is_ready (patch by Mark Hinds).
        - fixed an assert ("... == prev__cctx->idle_te")
          that could errronously trigger.
        - fix various large and small memleaks.
        - use a (hopefully) more stable cancel implementation
          that immediately frees the coroutine data.
        - cede/cede_notself return a status now.
        - added Coro::guard function.
        - added a global coroutine pool for jobs (on my machine,
          I can create and execute 48k simple coros/s with async,
          and 128k coros with async_pool).
        - Coro::AIO now uses the coroutine priority as io priority.

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.

4	root	1.191	TODO: destroy gets only called on cancel: fix(?)
5	root	1.200	TODO: fast reloads in cf cause segfaults (coro_state_free->destroy->crash)
6	root	1.173
7	root	1.201	3.4 Fri Jan 19 21:52:54 CET 2007
8	root	1.197	- remove t/09_timer.t, as it isn't really testing much
9			but was rather flaky in practise.
10	root	1.198	- async_pool coro would keep arguments and callback alive until
11			it was reused.
12	root	1.199	- cancellation of a coroutine could cause spurious idle calls
13			in cede_notself.
14	root	1.197
15	root	1.196	3.3 Sat Jan 6 03:45:00 CET 2007
16	root	1.187	- implement $coro->on_destroy.
17	root	1.188	- Coro::Event blocking semantics have been changed,
18			documented and - hopefully - improved.
19	root	1.184	- fix nice adding, not subtracting, from priority.
20	root	1.185	- fix ->prio and api_is_ready (patch by Mark Hinds).
21	root	1.190	- fixed an assert ("... == prev__cctx->idle_te")
22			that could errronously trigger.
23	root	1.192	- fix various large and small memleaks.
24	root	1.191	- use a (hopefully) more stable cancel implementation
25			that immediately frees the coroutine data.
26	root	1.194	- cede/cede_notself return a status now.
27	root	1.191	- added Coro::guard function.
28	root	1.193	- added a global coroutine pool for jobs (on my machine,
29			I can create and execute 48k simple coros/s with async,
30			and 128k coros with async_pool).
31	root	1.195	- Coro::AIO now uses the coroutine priority as io priority.
32	root	1.184
33	root	1.183	3.2 Fri Dec 22 05:07:09 CET 2006
34	root	1.179	- improve portability to slightly older perls.
35	root	1.180	- use cleaner coroutine destruction.
36	root	1.182	- simplify configuration for users.
37			- optionally (unrecommended) prefer perl functions over
38			their coro replacements.
39	root	1.179
40	root	1.178	3.11 Tue Dec 5 13:11:24 CET 2006
41			- fixed some bogus assert's, but as perl.h disables assert even
42			without NDEBUG (thank you very much), not too many people should
43			notice (that did include myself). Andreas König noticed, though :)
44			- do not save/restore PL_sortcxix on >= 5.9.x, it doesn't seem to have
45			it. Also noticed by Andreas König :)
46			- save/restore tainted status.
47			- verified to pass the testsuite on my 5.9.5.
48
49	root	1.177	3.1 Mon Dec 4 23:03:40 CET 2006
50			- INCOMPATIBLE CHANGE: $/ is now per-coroutine (but slow).
51	root	1.175	- incompatible change: transfer flags are now per-state.
52	root	1.173	- give a better error message on deadlock.
53	root	1.175	- document Coro::nready.
54	root	1.174	- enhanced testsuite.
55	root	1.169
56	root	1.172	3.01 Sun Dec 3 23:47:42 CET 2006
57			- forgot to include Coro::Timer.
58
59	root	1.171	3.0 Sun Dec 3 22:57:25 CET 2006
60	root	1.163	- the "FINALLY COMPLETELY STABLE" release (coming soon:
61			the "FAMOUS LAST WORDS" release).
62	root	1.166	- implement a new stack sharing algorithm, which uses a stack
63			pool (size currently hardcoded).
64	root	1.155	- make stack sharing mandatory (it no longer uses a heuristic).
65	root	1.157	- eval/die no longer cause weird problems under heavy use.
66	root	1.152	- Coro::Event could cause livelocks if it was used but
67	root	1.161	no Coro::Event watchers were used.
68	root	1.167	- Coro::Event now uses asynccheck as prepare does not
69			check for changed watchers.
70	root	1.170	- Coro::Event allows multiple waiting coros and will wake up one
71			per event.
72	root	1.152	- Coro::Event should be cleaner and more efficient now.
73	root	1.165	- new utility function Coro::unblock_sub.
74	root	1.164	- document the sad fact that Event is no longer reentrant.
75	root	1.163	- putting a coroutine into the ready queue twice could under
76			some circumstances lead to stack corruption.
77	root	1.161	- minor incompatibility: subclassing Coro::State is supported
78			directly now without going through a _coro_state member.
79	root	1.156	- state/coro switching is much faster now.
80	root	1.154	- very minor optimisations and code/documentation cleanup.
81	root	1.153	- avoid problems due to compiler inlining.
82	root	1.154	- removed timers from Coro::Timer -> use AnyEvent instead.
83			- replaced Coro::idle coroutine by (cleaner) idle handler.
84	root	1.156	- updated to newest libcoro.
85	root	1.159	- implement enhanced support for valgrind.
86	root	1.162	- implement is_ready and return value for ready.
87	root	1.168	- removed Coro::Cont, it was a misnomer (it's generators),
88			and it was somewhat annoying to get it right. Will come back
89			if somebody asks for it :)
90	root	1.163	- many ->wait methods and Coro::Event could return
91			spuriously without the event having happened.
92	root	1.146
93	root	1.145	2.5 Tue Nov 7 12:22:33 CET 2006
94	root	1.143	- made Coro::Util, Coro::Select, Coro::Handle and Coro::Socket
95			use AnyEvent, moved them to Coro/.
96	root	1.140	- added Coro::LWP which contains all the uglyness required to
97			make LWP non-blocking.
98			- should work with perl 5.9.x now (Andreas König made me do it).
99	root	1.141	- fixed another bug in Coro::Select when the timeout was undef.
100	root	1.136	- reuse PL_start_env for all coros, saves some memory per coroutine.
101			- manage PL_top_env differently, hopefully to avoid panic: top_env.
102	root	1.137	- timeout argument was not properly used in Coro::Socket.
103			- allow limited forms of subclassing in Coro::Handle/Coro::Socket.
104	root	1.138	- emulate undocumented(!) functionality of IO::Socket required
105			by LWP(!!).
106			- updated eg/lwp to work with newer lwp's.
107	root	1.140	- remove "FATAL: uncaught exception" prefix. Coroutines that die
108			kill the whole process, just as exceptions in the main "coroutine"
109			did already.
110	root	1.135
111	root	1.134	2.1 Wed Nov 1 23:01:13 CET 2006
112			- fix a long-standing bug in Coro::Select where select with
113			zero timeout would instead change the current default filehandle.
114	root	1.132	- use a simpler and hopefully more robust way to clone padlists
115			(uses less memory and a perl function instead of our own).
116			- coro can now create a stack guard area on many architectures.
117	root	1.134	- Coro::AIO properly reexports additional functions from IO::AIO.
118	root	1.132	- updated libcoro with a workaround for OS X,
119	root	1.134	pach and testing by Michael Schwern.
120	root	1.130
121	root	1.129	2.0 Tue Oct 24 05:47:17 CEST 2006
122	root	1.128	- support additional aio requests in Coro::AIO.
123
124	root	1.129	1.9 (never properly released due to a glitch)
125
126	root	1.127	1.8 Thu Feb 2 00:59:06 CET 2006
127	root	1.125	- applied suggested patch by SAMV to avoid problems during stupid
128			mark & sweep gc run.
129	root	1.126	- applied patch by Scott Walters for 5.9.3 compatibility.
130	root	1.125
131	root	1.124	1.7 Tue Dec 27 01:41:58 CET 2005
132	root	1.123	- added Coro::AIO, a thin wrapper around IO::AIO.
133	root	1.122	- improved Makefile.PL explanations.
134
135	root	1.119	1.6 Mon Dec 12 21:30:05 CET 2005
136	root	1.117	- additionally save PM_curpm might fix as-of-yet
137	root	1.121	unseen problems with regex matches being attributed to the
138	root	1.117	wrong package.
139	root	1.118	- add t/10_bugs.t, which currently checks against imho broken
140			perls that use 0.26MB of stack space per Perl_magic_get
141	root	1.121	invocation (newer linuxes) as opposed to the 0.0002MB perl
142			normally uses.
143	root	1.120	- make stacksize configurable for the ultimate debian experience.
144	root	1.117
145	root	1.116	1.51 Mon Dec 12 18:48:36 CET 2005
146			- remove debugging warn() accidentally left in Coro::Select.
147
148	root	1.115	1.5 Tue Nov 29 13:32:44 CET 2005
149	root	1.114	- use Coro::Event inside Coro::Select to avoid spurious deadlocks.
150	root	1.115	- fix Coro::Select 'select'.
151			- strict'ify some modules.
152	root	1.112	- libcoro errornously restored the SIGUSR2 handler to SIGUSR1.
153	root	1.115	- use XSLoader in selected modules.
154			- remove some 5.6 compatibility cruft.
155	root	1.112
156	root	1.111	1.4 Tue Sep 6 00:11:05 CEST 2005
157			- libcoro did not take into account the trampoline on amd64,
158			when 'l'inux method was used.
159
160	root	1.110	1.31 Tue Aug 30 23:31:33 CEST 2005
161			- some portability fixes/workarounds.
162
163	root	1.107	1.3 Sat Aug 20 03:08:56 CEST 2005
164	root	1.108	- no code changes. module seems to work fine.
165	root	1.106	- improve Coro::State docs, remove reference to nonexisting
166			Coro::State::flush method.
167	root	1.107	- no longer autodetect windows, present it as an option instead.
168	root	1.106
169	root	1.105	1.2 Mon May 16 02:00:55 CEST 2005
170	root	1.100	- included libcoro.c earlier in State.xs, might improve portability.
171	root	1.101	- use a faster and possibly more stable Coro::Cont implementation.
172	root	1.102	- accept x86_64 in addition to amd64 for optimized linux-amd64 support.
173	root	1.104	- fix bugs Coro::SemaphoreSet that could cause locks never to be freed.
174	root	1.105	- fix bugs in CoroAPI.h and document it in Coro::MakeMaker.
175	root	1.100
176	root	1.99	1.11 Thu Mar 3 18:00:52 CET 2005
177			- change of contact address.
178
179	root	1.98	1.1 Tue Feb 22 20:51:16 CET 2005
180	root	1.97	- support [l]inux method on amd64.
181	root	1.109	- allow some context switches while compiling/eval'ing.
182	root	1.97
183	root	1.96	1.0 Tue Aug 10 03:47:27 CEST 2004
184	root	1.95	- Event 0.89 fixes the bug again.
185	root	1.96	- fix the remaining(??) memleak. I didn't free the cache-AV for
186			padlists, so one AV per created anon-sub leaked.
187	root	1.95
188	pcg	1.94	0.97 Fri May 14 15:23:32 CEST 2004
189			- remove stupid gcc extension that was an experiment only anyway.
190
191	pcg	1.93	0.96 Thu May 13 18:09:29 CEST 2004
192	root	1.103	- tell people if they have yet another broken Event variant.
193	pcg	1.91	- made Coro to work _better_ with threads (it seems that, as long
194			as you use Coros in one thread only everything will work fine.
195			Looking at the perl source the problem might be missing locking
196			between Coro and some perl internal routines. That's not easily
197			fixable).
198	pcg	1.92	- (hopefully) got rid of the static xnext inside transfer.
199	pcg	1.91
200	pcg	1.90	0.95 Sun Feb 15 03:20:28 CET 2004
201	pcg	1.86	- removed Coro::State::flush, implemented a new and much
202			faster caching mechanism by attaching magic to the CV.
203	pcg	1.87	- a memleak with (real) closures remains.
204	pcg	1.88	- dramatically reduced size of stacks to 65536 (linux/x86), after
205			observing that even myhttpd never had more than a kilobyte
206			of stack in use (stack is still only physically allocated in
207			pagesize increments for systems suporting mmap).
208	pcg	1.89	- fix for a "cygwin-64" architecture added, proposed by Stefan Traby.
209	pcg	1.90	- fix for threaded perl.
210	pcg	1.86
211	pcg	1.85	0.9 Sun Nov 23 04:32:39 CET 2003
212	pcg	1.84	- fix a few very hard to track down but (of course) stupid
213			memory leaks.
214			- stringify version number to avoid locale problems :(.
215	pcg	1.85	- perl 5.9.0 does not have SvPADBUSY, reported by Scott Walters,
216			hopefully ignoring it "just works".
217	pcg	1.84
218	pcg	1.83	0.8 Wed Nov 5 19:38:40 CET 2003
219			- port to perl5.005_03, but only 5.8.x+ is supported!
220	pcg	1.82	- honor LocalAddr even without LocalPort in Coro::Socket.
221
222	root	1.81	0.7 Tue May 27 03:12:38 CEST 2003
223			- the version jump indicates some level of testing, not gobs
224			of new features.
225	root	1.80	- uh... I found the prompt function in ExtUtils::MakeMaker.
226			Highly correct stuff, that is...
227	root	1.81	- fixed(?) a bug with die's in coroutines causing "panic: top_env".
228			the fix is not well understood by the author, so beware :(.
229	root	1.80
230	root	1.79	0.652 Thu May 8 02:54:46 CEST 2003
231	root	1.76	- Applied patch by Slaven Rezic to set default to "s" on FreeBSD,
232	root	1.78	cause version 4 doesn't have ucontext.
233	root	1.77	- Benjamin Reed reported that setjmp works fine on darwin,
234			so preselect it.
235	root	1.76
236	root	1.75	0.651 Sat Mar 29 15:00:23 CET 2003
237			- fix a bug in Coro::Handle where some bytes could get lost
238			on reading, reported by jason@nichego.net.
239	root	1.74
240	root	1.73	0.65 Sun Mar 23 00:08:26 CET 2003
241	root	1.72	- added a README.linux-glibc.
242			- new module Coro::Select.
243			- also save/restore PL_comppad, fixes segfaults with 5.8.1.
244			(I never claimed that I know what I am doing ;).
245	root	1.73	- set default to setjmp/longjmp on non-x86-linux.
246	root	1.72
247	root	1.71	0.6 Thu Nov 21 11:09:06 CET 2002
248			- made lazy context switching the default.
249			- fixed the bug where SemaphoreSet::guard
250			was the same as timed_guard and timed_guard was missing.
251			- fix a memleak in Coro::Timer.
252			- reclassified context sharing as not experimental.
253
254	root	1.70	0.534 Sun Apr 14 03:05:12 CEST 2002
255	root	1.69	- fixed backspace => tab in header parsing (myhttpd).
256	root	1.70	- added eg/readline, for elmex.
257			- Coro::Event now calls ->start on first call instead of
258			->again, which created wrong timeouts for the first ->next.
259			- fixed a bug where Coro::Socket returned a closed socket instead
260			of nothing on ECONNREFUSED and similar error conditions.
261	root	1.69
262	root	1.68	0.533 Mon Feb 18 18:49:40 CET 2002
263			- adapt to finally working Event-0.85.
264			- fixed buggy event initialization (trapped under windows, but how
265			could it possibly have worked anywhere?)
266
267	root	1.67	0.532 Wed Jan 16 02:45:32 CET 2002
268	root	1.66	- removed the reference to pp_entersub, might work on
269			(some) win32 perls now (testsuite works under cygwin,
270			without Event, which freezes).
271	root	1.65
272	root	1.64	0.531 Mon Dec 10 22:18:44 CET 2001
273	root	1.63	- Fixed a bug in SemaphoreSet::timed_down.
274
275	root	1.64	0.53 Tue Nov 27 21:11:13 CET 2001
276	root	1.60	- some tests for Event.
277	root	1.61	- slightly different internal architecture to get refcnt into the object
278			and not the reference. might fix a few bugs, certainly did introduce
279			new ones.
280			- Coro::Timer (independent of Event).
281	root	1.62	- new timed_wait functions for Coro::Signal, Semaphore, SemaphoreSet.
282	root	1.60
283	root	1.64	0.52 Tue Nov 6 21:36:18 CET 2001
284	root	1.58	- ported to cygwin (trivial).
285			patch by Gerrit P. Haase <gp@familiehaase.de>.
286			- small setjmp code fix by Sullivan.DanielJ@epamail.epa.gov.
287
288	root	1.64	0.51 Thu Nov 1 20:39:01 CET 2001
289	root	1.54	- terminate/cancel now work properly (otherwise termination
290			could cause a "next coroutine is not and contains not..."
291			error.
292	root	1.55	- added Coro::Socket::shutdown.
293	root	1.56	- Coro::Event::loop no is the same as Event::loop.
294			- implemented terminate with args + join.
295	root	1.54
296	root	1.64	0.5 Fri Sep 28 16:15:35 CEST 2001
297	root	1.53	- fixed "print" on a Coro::Handle. The print method worked.
298	root	1.50	- small tweaks (seem to reduce memory consumption a lot)
299			in various modules.
300			- splendid use of "no warnings" scattered throughout.
301	root	1.52	- added Coro::Handle::rbuf, fixed Coro::Handle::fh.
302	root	1.48
303	root	1.47	0.49 Sun Sep 16 02:42:45 CEST 2001
304	root	1.43	- changed some method calls to function calls for speed
305			inside Coro::Handle.
306	root	1.44	- make Coro::Handle use an array instead of a hash for
307			speed reasons.
308			- IRIX mystery solved: it's SGI's NT, after all: "standard, huh?".
309			sjlj and ucontext should now work.
310			- IRIX-specific port for libcoro.
311	root	1.45	- swapped order of accept results to match IO::Socket.
312	root	1.46	- changed getsock/peername to sock/peername to match IO::Socket.
313			- fixed a bug that caused segfault when returning to main task
314			under some circumstances.
315			- other bugfixes.
316	root	1.43
317	root	1.42	0.45 Sun Sep 2 02:54:01 CEST 2001
318	root	1.36	- new method Coro::Handle::timeout.
319			- corrected speling of set...name to get...name in Coro::Socket.
320			- Coro::Socket::accept now returns a Coro::Socket, not a Coro::Handle.
321			- Coro::Handle now supports fileno and FILENO.
322			- added eg/myhttpd, a web server.
323	root	1.37	- Coro::Socket now accepts numeric ports as well as "port(number)"
324			syntax.
325	root	1.38	- moved some scheduling primitives into xs code. more to come.
326	root	1.39	- new simple priority system.
327	root	1.40	- implemented Coro::Event using XS, almost four times faster!
328	root	1.41	- small memory corruption problem fixed (boy that was difficult).
329	root	1.36
330	root	1.35	0.13 Wed Aug 8 16:53:07 CEST 2001
331	root	1.31	- new method Coro::Handle::readline.
332	root	1.34	- added eg/lwp and Coro::Handle::autoflush, to make LWP work.
333			(see eg/lwp on how to make LWP non-blocking).
334	root	1.31	- renamed Coro::Socket::new_inet to new.
335	root	1.32	- added Coro::Util, some utility functions.
336	root	1.33	- die/eval now works better (still get annoying (but true ;)
337			"Callback called exit" messages).
338	root	1.34	- Coro::Handle now supports timeout, and Coro::Socket Timeout.
339			- much better Coro::Socket support.
340	root	1.31
341			0.12 Fri Jul 27 04:19:01 CEST 2001
342	root	1.29	- do not use mmap if neither MAP_ANON nor MAP_ANONYMOUS is defined.
343	root	1.34	- very experimental stack sharing algorithm. not 100% safe but
344	root	1.28	should work well in practise ;)
345	root	1.30	- added Coro::RWLock.
346	root	1.31	- Coro::Specific now works.
347	root	1.28
348			0.11 Tue Jul 24 22:49:21 CEST 2001

354	root	1.23	- release candidate 3. A rather new internal structure :(
355	root	1.24	- the great renaming: Damian Conway gave me a suitable replacement
356			for yield.
357	root	1.23	- added Coro/libcoro, a portable coroutine implementation for C
358	root	1.22	(not even perl-dependent!!!), which can be used by Coro::State.
359	root	1.20	- renamed SAVE_DEFSV (on xs-level only) to avoid symbol clash in
360			perl-5.6.
361	root	1.16	- new function Coro::Event::idle.
362			- the idle process is now overriden
363			by default in Coro::Event.
364	root	1.17	- Coro::Channel now enforces the size.
365	root	1.18	- canceling events now works in all cases.
366	root	1.19	- Coro state now include $_ and $@.
367			- yet another bug workaround that I do not really understand :(
368	root	1.21	- new module Coro::Event::IO (very undocumented) to do
369			non-blocking i/o.
370	root	1.25	- performance tuning.
371	root	1.16
372	root	1.15	0.08 Thu Jul 19 06:13:25 CEST 2001
373	root	1.14	- release candidate 2 (new functionality).
374	root	1.13	- add Coro::State::flush function.
375			- transfer now supports a flags value (mostly for speed ATM).
376			- might compile and work in the presence of threads now.
377	root	1.14	- continuations have a saner syntax.
378	root	1.19	- no more memleaks.
379	root	1.13
380	root	1.12	0.07 Tue Jul 17 17:40:18 CEST 2001
381			- release candidate 1 ;)
382			- slightly nicer code.
383			- fixed a scheduling bug in Coro::Event.
384
385	root	1.11	0.06 Tue Jul 17 04:23:24 CEST 2001
386			- ok, I found the showstopper - the same sub must not be
387	root	1.9	re-entered in two different coroutines, otherwise => crash. I
388			see no easy solution to this problem, except by walking the call
389			chaing and saving/restoring the cv's, which is what I do now.
390	root	1.11	- memory leaks still latent, especially at thread termination.
391			- Coro::Event now works (haha).
392	root	1.9
393	root	1.8	0.05 Sun Jul 15 17:32:20 CEST 2001
394			- fixed a few issues in Coro::Event.
395			- I forgot to include Coro::Event in 0.04 :(:(:(
396
397	root	1.7	0.04 Sun Jul 15 05:24:59 CEST 2001
398	root	1.5	- @_ is now properly localized.
399	root	1.4	- Coro::State is now easier subclassable.
400			- Coro::Cont now coroutine-aware.
401			- Coro::Specific is a low-overhead module to create
402			coroutine-specific vars.
403	root	1.6	- Coro::Event provides a simple interface to Event.
404	root	1.4
405	root	1.3	0.03 Fri Jul 13 14:51:52 CEST 2001
406	root	1.4	- transfer() now implemented in XS (beware).
407			- new module Coro::Cont for really faked continuations.
408			- big internal architecture changes: Coro::State is now
409	root	1.3	really low-level and can thus be used to implement other
410	root	1.4	interesting things, While "Coro::" implements a process-like
411			model. Still crude and subject to change.
412	root	1.3	- $_ and $@ are no longer being localized.
413
414	root	1.2	0.02 Tue Jul 10 01:38:17 CEST 2001
415			- implemented "async" attribute.
416			- $_ and $@ are now localized.
417			- added Coro::Channel.
418			- more testcases, still no docs.
419
420	root	1.1	0.01 Tue Jul 3 02:18:41 CEST 2001
421			- original version; copied from Convert::Scalar.
