Revision history for Perl extension Coro.

1.7
        - 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.

113	root	1.72	- added a README.linux-glibc.
114			- new module Coro::Select.
115			- also save/restore PL_comppad, fixes segfaults with 5.8.1.
116			(I never claimed that I know what I am doing ;).
117	root	1.73	- set default to setjmp/longjmp on non-x86-linux.
118	root	1.72
119	root	1.71	0.6 Thu Nov 21 11:09:06 CET 2002
120			- made lazy context switching the default.
121			- fixed the bug where SemaphoreSet::guard
122			was the same as timed_guard and timed_guard was missing.
123			- fix a memleak in Coro::Timer.
124			- reclassified context sharing as not experimental.
125
126	root	1.70	0.534 Sun Apr 14 03:05:12 CEST 2002
127	root	1.69	- fixed backspace => tab in header parsing (myhttpd).
128	root	1.70	- added eg/readline, for elmex.
129			- Coro::Event now calls ->start on first call instead of
130			->again, which created wrong timeouts for the first ->next.
131			- fixed a bug where Coro::Socket returned a closed socket instead
132			of nothing on ECONNREFUSED and similar error conditions.
133	root	1.69
134	root	1.68	0.533 Mon Feb 18 18:49:40 CET 2002
135			- adapt to finally working Event-0.85.
136			- fixed buggy event initialization (trapped under windows, but how
137			could it possibly have worked anywhere?)
138
139	root	1.67	0.532 Wed Jan 16 02:45:32 CET 2002
140	root	1.66	- removed the reference to pp_entersub, might work on
141			(some) win32 perls now (testsuite works under cygwin,
142			without Event, which freezes).
143	root	1.65
144	root	1.64	0.531 Mon Dec 10 22:18:44 CET 2001
145	root	1.63	- Fixed a bug in SemaphoreSet::timed_down.
146
147	root	1.64	0.53 Tue Nov 27 21:11:13 CET 2001
148	root	1.60	- some tests for Event.
149	root	1.61	- slightly different internal architecture to get refcnt into the object
150			and not the reference. might fix a few bugs, certainly did introduce
151			new ones.
152			- Coro::Timer (independent of Event).
153	root	1.62	- new timed_wait functions for Coro::Signal, Semaphore, SemaphoreSet.
154	root	1.60
155	root	1.64	0.52 Tue Nov 6 21:36:18 CET 2001
156	root	1.58	- ported to cygwin (trivial).
157			patch by Gerrit P. Haase <gp@familiehaase.de>.
158			- small setjmp code fix by Sullivan.DanielJ@epamail.epa.gov.
159
160	root	1.64	0.51 Thu Nov 1 20:39:01 CET 2001
161	root	1.54	- terminate/cancel now work properly (otherwise termination
162			could cause a "next coroutine is not and contains not..."
163			error.
164	root	1.55	- added Coro::Socket::shutdown.
165	root	1.56	- Coro::Event::loop no is the same as Event::loop.
166			- implemented terminate with args + join.
167	root	1.54
168	root	1.64	0.5 Fri Sep 28 16:15:35 CEST 2001
169	root	1.53	- fixed "print" on a Coro::Handle. The print method worked.
170	root	1.50	- small tweaks (seem to reduce memory consumption a lot)
171			in various modules.
172			- splendid use of "no warnings" scattered throughout.
173	root	1.52	- added Coro::Handle::rbuf, fixed Coro::Handle::fh.
174	root	1.48
175	root	1.47	0.49 Sun Sep 16 02:42:45 CEST 2001
176	root	1.43	- changed some method calls to function calls for speed
177			inside Coro::Handle.
178	root	1.44	- make Coro::Handle use an array instead of a hash for
179			speed reasons.
180			- IRIX mystery solved: it's SGI's NT, after all: "standard, huh?".
181			sjlj and ucontext should now work.
182			- IRIX-specific port for libcoro.
183	root	1.45	- swapped order of accept results to match IO::Socket.
184	root	1.46	- changed getsock/peername to sock/peername to match IO::Socket.
185			- fixed a bug that caused segfault when returning to main task
186			under some circumstances.
187			- other bugfixes.
188	root	1.43
189	root	1.42	0.45 Sun Sep 2 02:54:01 CEST 2001
190	root	1.36	- new method Coro::Handle::timeout.
191			- corrected speling of set...name to get...name in Coro::Socket.
192			- Coro::Socket::accept now returns a Coro::Socket, not a Coro::Handle.
193			- Coro::Handle now supports fileno and FILENO.
194			- added eg/myhttpd, a web server.
195	root	1.37	- Coro::Socket now accepts numeric ports as well as "port(number)"
196			syntax.
197	root	1.38	- moved some scheduling primitives into xs code. more to come.
198	root	1.39	- new simple priority system.
199	root	1.40	- implemented Coro::Event using XS, almost four times faster!
200	root	1.41	- small memory corruption problem fixed (boy that was difficult).
201	root	1.36
202	root	1.35	0.13 Wed Aug 8 16:53:07 CEST 2001
203	root	1.31	- new method Coro::Handle::readline.
204	root	1.34	- added eg/lwp and Coro::Handle::autoflush, to make LWP work.
205			(see eg/lwp on how to make LWP non-blocking).
206	root	1.31	- renamed Coro::Socket::new_inet to new.
207	root	1.32	- added Coro::Util, some utility functions.
208	root	1.33	- die/eval now works better (still get annoying (but true ;)
209			"Callback called exit" messages).
210	root	1.34	- Coro::Handle now supports timeout, and Coro::Socket Timeout.
211			- much better Coro::Socket support.
212	root	1.31
213			0.12 Fri Jul 27 04:19:01 CEST 2001
214	root	1.29	- do not use mmap if neither MAP_ANON nor MAP_ANONYMOUS is defined.
215	root	1.34	- very experimental stack sharing algorithm. not 100% safe but
216	root	1.28	should work well in practise ;)
217	root	1.30	- added Coro::RWLock.
218	root	1.31	- Coro::Specific now works.
219	root	1.28
220			0.11 Tue Jul 24 22:49:21 CEST 2001
221	root	1.27	- added specialized hack for newer and older linux versions (fast).
222			- renamed Coro::Event::IO to Coro::Handle.
223			- new module Coro::Socket.
224
225	root	1.26	0.1 Tue Jul 24 01:47:53 CEST 2001
226	root	1.23	- release candidate 3. A rather new internal structure :(
227	root	1.24	- the great renaming: Damian Conway gave me a suitable replacement
228			for yield.
229	root	1.23	- added Coro/libcoro, a portable coroutine implementation for C
230	root	1.22	(not even perl-dependent!!!), which can be used by Coro::State.
231	root	1.20	- renamed SAVE_DEFSV (on xs-level only) to avoid symbol clash in
232			perl-5.6.
233	root	1.16	- new function Coro::Event::idle.
234			- the idle process is now overriden
235			by default in Coro::Event.
236	root	1.17	- Coro::Channel now enforces the size.
237	root	1.18	- canceling events now works in all cases.
238	root	1.19	- Coro state now include $_ and $@.
239			- yet another bug workaround that I do not really understand :(
240	root	1.21	- new module Coro::Event::IO (very undocumented) to do
241			non-blocking i/o.
242	root	1.25	- performance tuning.
243	root	1.16
244	root	1.15	0.08 Thu Jul 19 06:13:25 CEST 2001
245	root	1.14	- release candidate 2 (new functionality).
246	root	1.13	- add Coro::State::flush function.
247			- transfer now supports a flags value (mostly for speed ATM).
248			- might compile and work in the presence of threads now.
249	root	1.14	- continuations have a saner syntax.
250	root	1.19	- no more memleaks.
251	root	1.13
252	root	1.12	0.07 Tue Jul 17 17:40:18 CEST 2001
253			- release candidate 1 ;)
254			- slightly nicer code.
255			- fixed a scheduling bug in Coro::Event.
256
257	root	1.11	0.06 Tue Jul 17 04:23:24 CEST 2001
258			- ok, I found the showstopper - the same sub must not be
259	root	1.9	re-entered in two different coroutines, otherwise => crash. I
260			see no easy solution to this problem, except by walking the call
261			chaing and saving/restoring the cv's, which is what I do now.
262	root	1.11	- memory leaks still latent, especially at thread termination.
263			- Coro::Event now works (haha).
264	root	1.9
265	root	1.8	0.05 Sun Jul 15 17:32:20 CEST 2001
266			- fixed a few issues in Coro::Event.
267			- I forgot to include Coro::Event in 0.04 :(:(:(
268
269	root	1.7	0.04 Sun Jul 15 05:24:59 CEST 2001
270	root	1.5	- @_ is now properly localized.
271	root	1.4	- Coro::State is now easier subclassable.
272			- Coro::Cont now coroutine-aware.
273			- Coro::Specific is a low-overhead module to create
274			coroutine-specific vars.
275	root	1.6	- Coro::Event provides a simple interface to Event.
276	root	1.4
277	root	1.3	0.03 Fri Jul 13 14:51:52 CEST 2001
278	root	1.4	- transfer() now implemented in XS (beware).
279			- new module Coro::Cont for really faked continuations.
280			- big internal architecture changes: Coro::State is now
281	root	1.3	really low-level and can thus be used to implement other
282	root	1.4	interesting things, While "Coro::" implements a process-like
283			model. Still crude and subject to change.
284	root	1.3	- $_ and $@ are no longer being localized.
285
286	root	1.2	0.02 Tue Jul 10 01:38:17 CEST 2001
287			- implemented "async" attribute.
288			- $_ and $@ are now localized.
289			- added Coro::Channel.
290			- more testcases, still no docs.
291
292	root	1.1	0.01 Tue Jul 3 02:18:41 CEST 2001
293			- original version; copied from Convert::Scalar.
