3TODO: better (earlier) error messages on broken transfer's 3TODO: should explore PerlIO::via::CoroCede and PerlIO::via::CoroAIO.
4TODO: destroy gets only called on cancel: fix(?) 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)).
5 7
84.71 Sat May 24 20:01:27 CEST 2008
9 - fix a bug in Coro::AnyEvent ("Usage: Coro::AnyEvent::_schedule()").
10 - take advantage of async name resolution of AnyEvent::Util.
11 - work around brutal inet_aton override in Coro::LWP.
12 - take advantage of the readyhook in Coro::EV, for smoother
13 scheduling.
14
154.7 Sun May 11 00:32:19 CEST 2008
16 - completely reworked the Coro manpage.
17 - added Coro::AnyEvent, generic event loop integration.
18 - implement cancel, ready and kill commands in Coro::Debug.
19 - document find_coro in Coro::Debug.
20 - incompatible change: rename has_stack to has_cctx.
21 - Coro::AIO and Coro::BDB no longer force event model detection,
22 use AnyEvent::AIO and AnyEvent::BDB.
23
244.6 Sat Apr 26 10:05:14 CEST 2008
25 - INCOMPATIBLE CHANGE: sub/code attributes are no longer supported
26 by the Coro module. It was a mistake to have it in the first place.
27 - (experimental) support for activestate perl 5.10 (method "w").
28 - (experimental) support for strawberry perl (method "a").
29 - coro_sigelem_set did not return a value although it had to,
30 actual impact unknown.
31
324.51 Mon Apr 14 13:28:27 CEST 2008
33 - make it compile again on 5.8.
34
354.50 Thu Apr 10 09:43:17 CEST 2008
36 - I did it twice! (see 4.49).
37
384.49 Sun Apr 6 21:23:31 CEST 2008
39 - grr, instead of compiling the recent changes on 5.10 only they
40 were compiled on 5.8 only.
41
424.48 Sun Apr 6 20:36:46 CEST 2008
43 - allow coroutine switches during eval's under 5.10.x, as it seems
44 the parser is a per-interpreter option now, so this is safe
45 (this might fix the odd crashing bug).
46 - drop support for 5.9.x versions: they are dead, jim.
47
484.47 Sun Apr 6 00:37:52 CEST 2008
49 - force cctx allocation on API calls: we know we need to force one
50 and gcc actually manages to confuse our heuristic nowadays,
51 leading to crashes and worse.
52 - document force_cctx.
53
544.46 Fri Apr 4 22:05:43 CEST 2008
55 - upgrade libcoro, resulting in pthread-backend (which was only created
56 to fulfill the rules of the programming languages shootout).
57
584.45 Thu Mar 13 11:55:36 CET 2008
59 - fix a file leaking bug in eg/mhyttpd that would allow
60 downloading of any file (reported by oesi).
61 - fix deadlock bug in Coro::Channel (reported by Richard Hundt)
62 (also add testcase).
63 - support Broadcast option in Coro::Socket (patch by Richard Hundt,
64 apparently having loads of fun with that).
65 - implement $state->swap_defsv, ->swap_defav and document ->throw.
66
674.4 Wed Feb 13 16:44:29 CET 2008
68 - only assume .cfi pseudo isns exist on GNU/Linux.
69 - add get_timed method to Coro::Channels.
70 - fixed Coro::Debug manpage.
71 - perl 5.11 compatbility improvement based on patch by
72 Andreas König.
73
744.37 Sun Jan 20 11:25:23 CET 2008
75 - soften the check for an active parser for perl 5.10 (avoiding
76 "Coro::State::transfer called while parsing" in many cases).
77
784.36 Sun Jan 13 10:53:56 CET 2008
79 - reset diehook when terminating from an async_pool as to not
80 trigger any __DIE__ handlers.
81
824.35 Sun Jan 13 04:14:13 CET 2008
83 - "bt" debug command now displays any exceptions
84 from longmess and also skips the innermost
85 stackframes, giving more useufl output.
86 - allow backtraces in coroutines blocked in Coro::EV,
87 at a <1% speed hit.
88 - handle localising of $SIG{__WARN__} and __DIE__
89 properly (with a proper amount of dirty hacking).
90
914.34 Sat Dec 22 17:49:53 CET 2007
92 - upgrade to EV version 2.0 API.
93
944.33 Mon Dec 17 08:36:12 CET 2007
95 - make Coro::AIO etc. loadable in the absence of EV.
96
974.32 Mon Dec 17 07:46:02 CET 2007
98 - majorly improved Coro::Handle's performance with Coro::EV.
99 - implemented the until now mythical Coro::BDB module.
100 - specialcase EV in Coro::AIO and Coro::BDB for extra speed.
101
1024.31 Wed Dec 5 12:32:39 CET 2007
103 - remove warn statement form Coro::Util.
104
1054.3 Tue Dec 4 20:33:14 CET 2007
106 - calls to the idle function could cause stack corruption
107 when the stack changed.
108 - do no longer rely on the presence of EV::DNS if EV is used
109 (because it is gone), but instead take avdantage of EV::ADNS
110 if available.
111 - add ($) prototypes to all functions in Coro::Storable.
112 - use a conventional (safer) idle callback in Coro::EV.
113 - do accept quickly in Coro::Debug to avoid endless loops.
114
1154.22 Fri Nov 30 16:04:04 CET 2007
116 - really use optimised versions for Event and EV in Coro::Util
117 and Coro::Handle.
118
1194.21 Sun Nov 25 10:48:59 CET 2007
120 - fix a spurious memory read.
121 - Coro::EV no longer keeps the eventloop "alive".
122
1234.2 Fri Nov 9 20:47:05 CET 2007
124 - enable/disable tracing from a new coroutine, not a pooled one.
125 - fix a memleak in Coro::Event.
126 - removed killall call from fork_eval.
127 - made sure store_fd is already loaded so that fork_eval
128 does not have to parse autoload in each subprocess.
129 - only use assembly method if -O switch is in $Config{optimize}.
130 - add (optional) Coro::EV module, so far the best event loop module
131 directly supported by Coro.
132 - if the event model is EV, use EV::DNS to resolve
133 stuff in Coro::Util.
134 - don't get confused by multiple event notifications in Coro::Handle.
135 - initial support for EV (libevent interface).
136 - require Event and EV using configure_requires, to force their existance.
137
1384.13 Wed Oct 24 07:26:45 CEST 2007
139 - add Coro::Storable::blocking_thaw.
140 - use a vastly more complicated technique to localise
141 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
142 - use a coroutine for the idle callback Coro::Event,
143 instead of running Event in the current coroutine context.
144 This also catches recursive invocations.
145 - actually report fork errors in gethostbyname and inet_aton.
146
1474.11 Thu Oct 11 02:40:24 CEST 2007
148 - port to threaded perls.
149
1504.1 Thu Oct 11 02:38:16 CEST 2007
151 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
152 be local to each coro (see Coro::State).
153 - incompatible change: for very deep reasons, cede and cede_notself
154 cannot return anything, so nothing will be returned.
155 - possibly bring back 5.10 compatibility (untested).
156 - work around stupid (and wrong) warning on 5.10 :(.
157 - overlay the saved state over the context stack. This saves
158 a few hundred bytes per coroutine on average and also
159 speeds up context switching a bit.
160 - further tune default stack sizes.
161 - (more) correctly calculate stack usage in coro_rss.
162 - Coro::Storable::blocking_* did not properly lock
163 resulting in races between coroutines.
164 - added Coro::Storable::guard.
165 - stopping to trace a coroutine could destroy the cctx of
166 an unrelated coroutine.
167 - explain the relationship between Perl and C coroutines in
168 more detail in Coro::State.
169 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
170 causing a fork per resolve. This also affected Coro::Socket.
171 - switch to a separate stack in $coro->call/eval to avoid
172 invalidating pointers.
173
1744.03 Sat Oct 6 21:24:00 CEST 2007
175 - added Coro::throw method.
176 - minor code cleanups.
177
1784.02 Sat Oct 6 02:36:47 CEST 2007
179 - fix a very minor per-coroutine memleak (a single codereference).
180 - fixed a bug where the currently in-use c context would be freed
181 prematurely (can happen only when programs change the stacksize
182 or use tracing).
183 - tracing can no longer keep a coro alive after it terminated.
184 - do static branch prediction in the common path for gcc. gives
185 about 2-5% speed improvement here.
186
1874.01 Fri Oct 5 22:10:49 CEST 2007
188 - instead of recreating *a* standard output handle we simply
189 use STDOUT, which is faster and hopefully more robust.
190
1914.0 Fri Oct 5 12:56:00 CEST 2007
192 - incompatibly changed Coro::Storable::freeze.
193 - major new feature: added Coro::Debug, for interactive coroutine
194 debugging, tracing and much more.
195 - major bug fix: unbelievable, but true: $_, $/ and many other
196 "saved" variables actually weren't being saved. This has been fixed,
197 of course, while increasing performance while losing all the save
198 flags.
199 - save flags are gone, and all the api functions dealing with them.
200 - added Coro::Semaphore::adjust.
201 - added Coro::Util::fork_eval.
202 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
203 - added Coro::killall.
204 - reduce initial stack sizes to allow for "micro-coroutines".
205 - better async_pool resource management, moved parts of async_pool
206 handling to XS (major speed improvement).
207 - actually croak before modifying important data structures.
208 - refuse to transfer while compiling.
209 - possibly support eval EXPR better now.
210 - enable assembly per default on linux+bsd x86+amd64.
211 - all internal members were renamed _something for easier subclassing.
212 - many minor tweaks.
213
2143.63 Wed May 16 14:10:06 CEST 2007
215 - implement handcoded assembly for x86/amd64 SVR ABI.
216
2173.62 Fri Apr 27 21:36:06 CEST 2007
218 - upgrade libcoro (which might set unwind info correctly).
219 - change default on linux to setjmp/longjmp.
220
2213.61 Thu Apr 19 12:36:18 CEST 2007
222 - Coro::Storable caused an endless loop when thawing invalid
223 pst's sometimes.
224 - use a Semaphore in Coro::Storable, as Storable doesn't
225 seem to be reentrant (although it is documented to
226 be threadsafe...).
227 - fix Coro::Signal to bring back the original unreliable
228 but stateful semantics.
229 - fixed a lot of typos in Coro.pm (patch submitted by David
230 Steinbrunner, which applied flawlessly).
231
2323.6 Sat Apr 14 17:13:31 CEST 2007
6 - added some bugfixes to get eg/myhttpd working again. 233 - added some bugfixes to get eg/myhttpd working again.
234 - added Coro::Storable for often-cede'ing freeze/thaw.
235 - try to do a clean exit when a coroutine calls exit
236 (EXPERIMENTAL).
237 - got rid of indirect call through _coro_init.
238 - updated the partly antique examples in eg/ to
239 work again and be a bit less magic, too.
240 - fixed Coro::Signal semantics to work as documented again.

83.55 Sun Mar 25 01:20:47 CET 2007 2423.55 Sun Mar 25 01:20:47 CET 2007
9 - add SAVE_DEFFH to save the default filehandle and enable 243 - add SAVE_DEFFH to save the default filehandle and enable
10 it by default. 244 it by default.
11 - finally move socket-operations from Coro::Socket to Coro::Handle 245 - finally move socket-operations from Coro::Socket to Coro::Handle
