Revision history for Perl extension Coro.

TODO: Coro::Select (select) and "" both don'T work

        - libcoro errornously restored the SIGUSR2 handler to SIGUSR1.

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.

138
139	root	1.64	0.51 Thu Nov 1 20:39:01 CET 2001
140	root	1.54	- terminate/cancel now work properly (otherwise termination
141			could cause a "next coroutine is not and contains not..."
142			error.
143	root	1.55	- added Coro::Socket::shutdown.
144	root	1.56	- Coro::Event::loop no is the same as Event::loop.
145			- implemented terminate with args + join.
146	root	1.54
147	root	1.64	0.5 Fri Sep 28 16:15:35 CEST 2001
148	root	1.53	- fixed "print" on a Coro::Handle. The print method worked.
149	root	1.50	- small tweaks (seem to reduce memory consumption a lot)
150			in various modules.
151			- splendid use of "no warnings" scattered throughout.
152	root	1.52	- added Coro::Handle::rbuf, fixed Coro::Handle::fh.
153	root	1.48
154	root	1.47	0.49 Sun Sep 16 02:42:45 CEST 2001
155	root	1.43	- changed some method calls to function calls for speed
156			inside Coro::Handle.
157	root	1.44	- make Coro::Handle use an array instead of a hash for
158			speed reasons.
159			- IRIX mystery solved: it's SGI's NT, after all: "standard, huh?".
160			sjlj and ucontext should now work.
161			- IRIX-specific port for libcoro.
162	root	1.45	- swapped order of accept results to match IO::Socket.
163	root	1.46	- changed getsock/peername to sock/peername to match IO::Socket.
164			- fixed a bug that caused segfault when returning to main task
165			under some circumstances.
166			- other bugfixes.
167	root	1.43
168	root	1.42	0.45 Sun Sep 2 02:54:01 CEST 2001
169	root	1.36	- new method Coro::Handle::timeout.
170			- corrected speling of set...name to get...name in Coro::Socket.
171			- Coro::Socket::accept now returns a Coro::Socket, not a Coro::Handle.
172			- Coro::Handle now supports fileno and FILENO.
173			- added eg/myhttpd, a web server.
174	root	1.37	- Coro::Socket now accepts numeric ports as well as "port(number)"
175			syntax.
176	root	1.38	- moved some scheduling primitives into xs code. more to come.
177	root	1.39	- new simple priority system.
178	root	1.40	- implemented Coro::Event using XS, almost four times faster!
179	root	1.41	- small memory corruption problem fixed (boy that was difficult).
180	root	1.36
181	root	1.35	0.13 Wed Aug 8 16:53:07 CEST 2001
182	root	1.31	- new method Coro::Handle::readline.
183	root	1.34	- added eg/lwp and Coro::Handle::autoflush, to make LWP work.
184			(see eg/lwp on how to make LWP non-blocking).

186	root	1.32	- added Coro::Util, some utility functions.
187	root	1.33	- die/eval now works better (still get annoying (but true ;)
188			"Callback called exit" messages).
189	root	1.34	- Coro::Handle now supports timeout, and Coro::Socket Timeout.
190			- much better Coro::Socket support.
191	root	1.31
192			0.12 Fri Jul 27 04:19:01 CEST 2001
193	root	1.29	- do not use mmap if neither MAP_ANON nor MAP_ANONYMOUS is defined.
194	root	1.34	- very experimental stack sharing algorithm. not 100% safe but
195	root	1.28	should work well in practise ;)
196	root	1.30	- added Coro::RWLock.
197	root	1.31	- Coro::Specific now works.
198	root	1.28
199			0.11 Tue Jul 24 22:49:21 CEST 2001
200	root	1.27	- added specialized hack for newer and older linux versions (fast).
201			- renamed Coro::Event::IO to Coro::Handle.
202			- new module Coro::Socket.
203
204	root	1.26	0.1 Tue Jul 24 01:47:53 CEST 2001
205	root	1.23	- release candidate 3. A rather new internal structure :(
206	root	1.24	- the great renaming: Damian Conway gave me a suitable replacement
207			for yield.
208	root	1.23	- added Coro/libcoro, a portable coroutine implementation for C
209	root	1.22	(not even perl-dependent!!!), which can be used by Coro::State.
210	root	1.20	- renamed SAVE_DEFSV (on xs-level only) to avoid symbol clash in
211			perl-5.6.
212	root	1.16	- new function Coro::Event::idle.
213			- the idle process is now overriden
214			by default in Coro::Event.
215	root	1.17	- Coro::Channel now enforces the size.
216	root	1.18	- canceling events now works in all cases.
217	root	1.19	- Coro state now include $_ and $@.
218			- yet another bug workaround that I do not really understand :(
219	root	1.21	- new module Coro::Event::IO (very undocumented) to do
220			non-blocking i/o.
221	root	1.25	- performance tuning.
222	root	1.16
223	root	1.15	0.08 Thu Jul 19 06:13:25 CEST 2001
224	root	1.14	- release candidate 2 (new functionality).
225	root	1.13	- add Coro::State::flush function.
226			- transfer now supports a flags value (mostly for speed ATM).
227			- might compile and work in the presence of threads now.
228	root	1.14	- continuations have a saner syntax.
229	root	1.19	- no more memleaks.
230	root	1.13
231	root	1.12	0.07 Tue Jul 17 17:40:18 CEST 2001
232			- release candidate 1 ;)
233			- slightly nicer code.
234			- fixed a scheduling bug in Coro::Event.
235
236	root	1.11	0.06 Tue Jul 17 04:23:24 CEST 2001
237			- ok, I found the showstopper - the same sub must not be
238	root	1.9	re-entered in two different coroutines, otherwise => crash. I
239			see no easy solution to this problem, except by walking the call
240			chaing and saving/restoring the cv's, which is what I do now.
241	root	1.11	- memory leaks still latent, especially at thread termination.
242			- Coro::Event now works (haha).
243	root	1.9
244	root	1.8	0.05 Sun Jul 15 17:32:20 CEST 2001
245			- fixed a few issues in Coro::Event.
246			- I forgot to include Coro::Event in 0.04 :(:(:(
247
248	root	1.7	0.04 Sun Jul 15 05:24:59 CEST 2001
249	root	1.5	- @_ is now properly localized.
250	root	1.4	- Coro::State is now easier subclassable.
251			- Coro::Cont now coroutine-aware.
252			- Coro::Specific is a low-overhead module to create
253			coroutine-specific vars.
254	root	1.6	- Coro::Event provides a simple interface to Event.
255	root	1.4
256	root	1.3	0.03 Fri Jul 13 14:51:52 CEST 2001
257	root	1.4	- transfer() now implemented in XS (beware).
258			- new module Coro::Cont for really faked continuations.
259			- big internal architecture changes: Coro::State is now
260	root	1.3	really low-level and can thus be used to implement other
261	root	1.4	interesting things, While "Coro::" implements a process-like
262			model. Still crude and subject to change.
263	root	1.3	- $_ and $@ are no longer being localized.
264
265	root	1.2	0.02 Tue Jul 10 01:38:17 CEST 2001
266			- implemented "async" attribute.
267			- $_ and $@ are now localized.
268			- added Coro::Channel.
269			- more testcases, still no docs.
270
271	root	1.1	0.01 Tue Jul 3 02:18:41 CEST 2001
272			- original version; copied from Convert::Scalar.
