3TODO: better (earlier) error messages on broken transfer's
4TODO: destroy gets only called on cancel: fix(?)
5TODO: should explore PerlIO::via::CoroCede and PerlIO::via::CoroAIO. 3TODO: should explore PerlIO::via::CoroCede and PerlIO::via::CoroAIO.
4TODO: maybe implement a default message channel, very much like Erlang's
5 actor model (which is cool in a lot of important aspects (failures!),
6 but very lacking in others (higher level ipc)).

7TODO: fix Coro::Signal once and for all 84.72 Sun May 25 05:14:36 CEST 2008
9 - tweak META.yaml a bit, unfortunately, there is no documented way
10 to have optional dependencies with CPAN. doh :(
11 - avoid running some tests on windows because they would fail due to
12 perl bug (broken fork, broken pipes...).
13 - work around perl on windows bugs where perl returns undocumented
14 error codes for sysread, syswrite etc. by taking advantage
15 of AnyEvent's workaround for that problem.
16 - use AnyEvent::Util::fh_nonblocking in Coro::Handle to work around
17 a common perl implementation bug on windows.
18 - use unix domain sockets in testsuite to work around
19 common perl implementation bugs on widows (they are emulated by
20 tcp sockets on windows. ugh.)
8 21
93.61 224.71 Sat May 24 20:01:27 CEST 2008
23 - fix a bug in Coro::AnyEvent ("Usage: Coro::AnyEvent::_schedule()").
24 - take advantage of async name resolution of AnyEvent::Util.
25 - work around brutal inet_aton override in Coro::LWP.
26 - take advantage of the readyhook in Coro::EV, for smoother
27 scheduling.
28
294.7 Sun May 11 00:32:19 CEST 2008
30 - completely reworked the Coro manpage.
31 - added Coro::AnyEvent, generic event loop integration.
32 - implement cancel, ready and kill commands in Coro::Debug.
33 - document find_coro in Coro::Debug.
34 - incompatible change: rename has_stack to has_cctx.
35 - Coro::AIO and Coro::BDB no longer force event model detection,
36 use AnyEvent::AIO and AnyEvent::BDB.
37
384.6 Sat Apr 26 10:05:14 CEST 2008
39 - INCOMPATIBLE CHANGE: sub/code attributes are no longer supported
40 by the Coro module. It was a mistake to have it in the first place.
41 - (experimental) support for activestate perl 5.10 (method "w").
42 - (experimental) support for strawberry perl (method "a").
43 - coro_sigelem_set did not return a value although it had to,
44 actual impact unknown.
45
464.51 Mon Apr 14 13:28:27 CEST 2008
47 - make it compile again on 5.8.
48
494.50 Thu Apr 10 09:43:17 CEST 2008
50 - I did it twice! (see 4.49).
51
524.49 Sun Apr 6 21:23:31 CEST 2008
53 - grr, instead of compiling the recent changes on 5.10 only they
54 were compiled on 5.8 only.
55
564.48 Sun Apr 6 20:36:46 CEST 2008
57 - allow coroutine switches during eval's under 5.10.x, as it seems
58 the parser is a per-interpreter option now, so this is safe
59 (this might fix the odd crashing bug).
60 - drop support for 5.9.x versions: they are dead, jim.
61
624.47 Sun Apr 6 00:37:52 CEST 2008
63 - force cctx allocation on API calls: we know we need to force one
64 and gcc actually manages to confuse our heuristic nowadays,
65 leading to crashes and worse.
66 - document force_cctx.
67
684.46 Fri Apr 4 22:05:43 CEST 2008
69 - upgrade libcoro, resulting in pthread-backend (which was only created
70 to fulfill the rules of the programming languages shootout).
71
724.45 Thu Mar 13 11:55:36 CET 2008
73 - fix a file leaking bug in eg/mhyttpd that would allow
74 downloading of any file (reported by oesi).
75 - fix deadlock bug in Coro::Channel (reported by Richard Hundt)
76 (also add testcase).
77 - support Broadcast option in Coro::Socket (patch by Richard Hundt,
78 apparently having loads of fun with that).
79 - implement $state->swap_defsv, ->swap_defav and document ->throw.
80
814.4 Wed Feb 13 16:44:29 CET 2008
82 - only assume .cfi pseudo isns exist on GNU/Linux.
83 - add get_timed method to Coro::Channels.
84 - fixed Coro::Debug manpage.
85 - perl 5.11 compatbility improvement based on patch by
86 Andreas König.
87
884.37 Sun Jan 20 11:25:23 CET 2008
89 - soften the check for an active parser for perl 5.10 (avoiding
90 "Coro::State::transfer called while parsing" in many cases).
91
924.36 Sun Jan 13 10:53:56 CET 2008
93 - reset diehook when terminating from an async_pool as to not
94 trigger any __DIE__ handlers.
95
964.35 Sun Jan 13 04:14:13 CET 2008
97 - "bt" debug command now displays any exceptions
98 from longmess and also skips the innermost
99 stackframes, giving more useufl output.
100 - allow backtraces in coroutines blocked in Coro::EV,
101 at a <1% speed hit.
102 - handle localising of $SIG{__WARN__} and __DIE__
103 properly (with a proper amount of dirty hacking).
104
1054.34 Sat Dec 22 17:49:53 CET 2007
106 - upgrade to EV version 2.0 API.
107
1084.33 Mon Dec 17 08:36:12 CET 2007
109 - make Coro::AIO etc. loadable in the absence of EV.
110
1114.32 Mon Dec 17 07:46:02 CET 2007
112 - majorly improved Coro::Handle's performance with Coro::EV.
113 - implemented the until now mythical Coro::BDB module.
114 - specialcase EV in Coro::AIO and Coro::BDB for extra speed.
115
1164.31 Wed Dec 5 12:32:39 CET 2007
117 - remove warn statement form Coro::Util.
118
1194.3 Tue Dec 4 20:33:14 CET 2007
120 - calls to the idle function could cause stack corruption
121 when the stack changed.
122 - do no longer rely on the presence of EV::DNS if EV is used
123 (because it is gone), but instead take avdantage of EV::ADNS
124 if available.
125 - add ($) prototypes to all functions in Coro::Storable.
126 - use a conventional (safer) idle callback in Coro::EV.
127 - do accept quickly in Coro::Debug to avoid endless loops.
128
1294.22 Fri Nov 30 16:04:04 CET 2007
130 - really use optimised versions for Event and EV in Coro::Util
131 and Coro::Handle.
132
1334.21 Sun Nov 25 10:48:59 CET 2007
134 - fix a spurious memory read.
135 - Coro::EV no longer keeps the eventloop "alive".
136
1374.2 Fri Nov 9 20:47:05 CET 2007
138 - enable/disable tracing from a new coroutine, not a pooled one.
139 - fix a memleak in Coro::Event.
140 - removed killall call from fork_eval.
141 - made sure store_fd is already loaded so that fork_eval
142 does not have to parse autoload in each subprocess.
143 - only use assembly method if -O switch is in $Config{optimize}.
144 - add (optional) Coro::EV module, so far the best event loop module
145 directly supported by Coro.
146 - if the event model is EV, use EV::DNS to resolve
147 stuff in Coro::Util.
148 - don't get confused by multiple event notifications in Coro::Handle.
149 - initial support for EV (libevent interface).
150 - require Event and EV using configure_requires, to force their existance.
151
1524.13 Wed Oct 24 07:26:45 CEST 2007
153 - add Coro::Storable::blocking_thaw.
154 - use a vastly more complicated technique to localise
155 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
156 - use a coroutine for the idle callback Coro::Event,
157 instead of running Event in the current coroutine context.
158 This also catches recursive invocations.
159 - actually report fork errors in gethostbyname and inet_aton.
160
1614.11 Thu Oct 11 02:40:24 CEST 2007
162 - port to threaded perls.
163
1644.1 Thu Oct 11 02:38:16 CEST 2007
165 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
166 be local to each coro (see Coro::State).
167 - incompatible change: for very deep reasons, cede and cede_notself
168 cannot return anything, so nothing will be returned.
169 - possibly bring back 5.10 compatibility (untested).
170 - work around stupid (and wrong) warning on 5.10 :(.
171 - overlay the saved state over the context stack. This saves
172 a few hundred bytes per coroutine on average and also
173 speeds up context switching a bit.
174 - further tune default stack sizes.
175 - (more) correctly calculate stack usage in coro_rss.
176 - Coro::Storable::blocking_* did not properly lock
177 resulting in races between coroutines.
178 - added Coro::Storable::guard.
179 - stopping to trace a coroutine could destroy the cctx of
180 an unrelated coroutine.
181 - explain the relationship between Perl and C coroutines in
182 more detail in Coro::State.
183 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
184 causing a fork per resolve. This also affected Coro::Socket.
185 - switch to a separate stack in $coro->call/eval to avoid
186 invalidating pointers.
187
1884.03 Sat Oct 6 21:24:00 CEST 2007
189 - added Coro::throw method.
190 - minor code cleanups.
191
1924.02 Sat Oct 6 02:36:47 CEST 2007
193 - fix a very minor per-coroutine memleak (a single codereference).
194 - fixed a bug where the currently in-use c context would be freed
195 prematurely (can happen only when programs change the stacksize
196 or use tracing).
197 - tracing can no longer keep a coro alive after it terminated.
198 - do static branch prediction in the common path for gcc. gives
199 about 2-5% speed improvement here.
200
2014.01 Fri Oct 5 22:10:49 CEST 2007
202 - instead of recreating *a* standard output handle we simply
203 use STDOUT, which is faster and hopefully more robust.
204
2054.0 Fri Oct 5 12:56:00 CEST 2007
206 - incompatibly changed Coro::Storable::freeze.
207 - major new feature: added Coro::Debug, for interactive coroutine
208 debugging, tracing and much more.
209 - major bug fix: unbelievable, but true: $_, $/ and many other
210 "saved" variables actually weren't being saved. This has been fixed,
211 of course, while increasing performance while losing all the save
212 flags.
213 - save flags are gone, and all the api functions dealing with them.
214 - added Coro::Semaphore::adjust.
215 - added Coro::Util::fork_eval.
216 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
217 - added Coro::killall.
218 - reduce initial stack sizes to allow for "micro-coroutines".
219 - better async_pool resource management, moved parts of async_pool
220 handling to XS (major speed improvement).
221 - actually croak before modifying important data structures.
222 - refuse to transfer while compiling.
223 - possibly support eval EXPR better now.
224 - enable assembly per default on linux+bsd x86+amd64.
225 - all internal members were renamed _something for easier subclassing.
226 - many minor tweaks.
227
2283.63 Wed May 16 14:10:06 CEST 2007
229 - implement handcoded assembly for x86/amd64 SVR ABI.
230
2313.62 Fri Apr 27 21:36:06 CEST 2007
232 - upgrade libcoro (which might set unwind info correctly).
233 - change default on linux to setjmp/longjmp.
234
2353.61 Thu Apr 19 12:36:18 CEST 2007
236 - Coro::Storable caused an endless loop when thawing invalid
237 pst's sometimes.
10 - use a Semaphore in Coro::Storable, as Storable doesn't 238 - use a Semaphore in Coro::Storable, as Storable doesn't
11 seem to be reentrant (although it should be...). 239 seem to be reentrant (although it is documented to
240 be threadsafe...).
241 - fix Coro::Signal to bring back the original unreliable
242 but stateful semantics.
243 - fixed a lot of typos in Coro.pm (patch submitted by David
244 Steinbrunner, which applied flawlessly).
12 245
133.6 Sat Apr 14 17:13:31 CEST 2007 2463.6 Sat Apr 14 17:13:31 CEST 2007
14 - added some bugfixes to get eg/myhttpd working again. 247 - added some bugfixes to get eg/myhttpd working again.
15 - added Coro::Storable for often-cede'ing freeze/thaw. 248 - added Coro::Storable for often-cede'ing freeze/thaw.
16 - try to do a clean exit when a coroutine calls exit 249 - try to do a clean exit when a coroutine calls exit
