Revision history for Perl extension Coro.

1.1 Tue Feb 22 20:51:16 CET 2005
        - support [l]inux method on amd64.
        - make some contetx switches while compiling work.

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 anothe rbroken 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.

156	root	1.34	- added eg/lwp and Coro::Handle::autoflush, to make LWP work.
157			(see eg/lwp on how to make LWP non-blocking).
158	root	1.31	- renamed Coro::Socket::new_inet to new.
159	root	1.32	- added Coro::Util, some utility functions.
160	root	1.33	- die/eval now works better (still get annoying (but true ;)
161			"Callback called exit" messages).
162	root	1.34	- Coro::Handle now supports timeout, and Coro::Socket Timeout.
163			- much better Coro::Socket support.
164	root	1.31
165			0.12 Fri Jul 27 04:19:01 CEST 2001
166	root	1.29	- do not use mmap if neither MAP_ANON nor MAP_ANONYMOUS is defined.
167	root	1.34	- very experimental stack sharing algorithm. not 100% safe but
168	root	1.28	should work well in practise ;)
169	root	1.30	- added Coro::RWLock.
170	root	1.31	- Coro::Specific now works.
171	root	1.28
172			0.11 Tue Jul 24 22:49:21 CEST 2001
173	root	1.27	- added specialized hack for newer and older linux versions (fast).
174			- renamed Coro::Event::IO to Coro::Handle.
175			- new module Coro::Socket.
176
177	root	1.26	0.1 Tue Jul 24 01:47:53 CEST 2001
178	root	1.23	- release candidate 3. A rather new internal structure :(
179	root	1.24	- the great renaming: Damian Conway gave me a suitable replacement
180			for yield.
181	root	1.23	- added Coro/libcoro, a portable coroutine implementation for C
182	root	1.22	(not even perl-dependent!!!), which can be used by Coro::State.
183	root	1.20	- renamed SAVE_DEFSV (on xs-level only) to avoid symbol clash in
184			perl-5.6.
185	root	1.16	- new function Coro::Event::idle.
186			- the idle process is now overriden
187			by default in Coro::Event.
188	root	1.17	- Coro::Channel now enforces the size.
189	root	1.18	- canceling events now works in all cases.
190	root	1.19	- Coro state now include $_ and $@.
191			- yet another bug workaround that I do not really understand :(
192	root	1.21	- new module Coro::Event::IO (very undocumented) to do
193			non-blocking i/o.
194	root	1.25	- performance tuning.
195	root	1.16
196	root	1.15	0.08 Thu Jul 19 06:13:25 CEST 2001
197	root	1.14	- release candidate 2 (new functionality).
198	root	1.13	- add Coro::State::flush function.
199			- transfer now supports a flags value (mostly for speed ATM).
200			- might compile and work in the presence of threads now.
201	root	1.14	- continuations have a saner syntax.
202	root	1.19	- no more memleaks.
203	root	1.13
204	root	1.12	0.07 Tue Jul 17 17:40:18 CEST 2001
205			- release candidate 1 ;)
206			- slightly nicer code.
207			- fixed a scheduling bug in Coro::Event.
208
209	root	1.11	0.06 Tue Jul 17 04:23:24 CEST 2001
210			- ok, I found the showstopper - the same sub must not be
211	root	1.9	re-entered in two different coroutines, otherwise => crash. I
212			see no easy solution to this problem, except by walking the call
213			chaing and saving/restoring the cv's, which is what I do now.
214	root	1.11	- memory leaks still latent, especially at thread termination.
215			- Coro::Event now works (haha).
216	root	1.9
217	root	1.8	0.05 Sun Jul 15 17:32:20 CEST 2001
218			- fixed a few issues in Coro::Event.
219			- I forgot to include Coro::Event in 0.04 :(:(:(
220
221	root	1.7	0.04 Sun Jul 15 05:24:59 CEST 2001
222	root	1.5	- @_ is now properly localized.
223	root	1.4	- Coro::State is now easier subclassable.
224			- Coro::Cont now coroutine-aware.
225			- Coro::Specific is a low-overhead module to create
226			coroutine-specific vars.
227	root	1.6	- Coro::Event provides a simple interface to Event.
228	root	1.4
229	root	1.3	0.03 Fri Jul 13 14:51:52 CEST 2001
230	root	1.4	- transfer() now implemented in XS (beware).
231			- new module Coro::Cont for really faked continuations.
232			- big internal architecture changes: Coro::State is now
233	root	1.3	really low-level and can thus be used to implement other
234	root	1.4	interesting things, While "Coro::" implements a process-like
235			model. Still crude and subject to change.
236	root	1.3	- $_ and $@ are no longer being localized.
237
238	root	1.2	0.02 Tue Jul 10 01:38:17 CEST 2001
239			- implemented "async" attribute.
240			- $_ and $@ are now localized.
241			- added Coro::Channel.
242			- more testcases, still no docs.
243
244	root	1.1	0.01 Tue Jul 3 02:18:41 CEST 2001
245			- original version; copied from Convert::Scalar.
