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
5 (which is cool in a lot of important aspects (failures!),
6 but very lacking in others (higher level ipc)).

63.5 84.4 Wed Feb 13 16:44:29 CET 2008
9 - only assume .cfi pseudo isns exist on GNU/Linux.
10 - add get_timed method to Coro::Channels.
11 - fixed Coro::Debug manpage.
12 - perl 5.11 compatbility improvement based on patch by
13 Andreas König.
14
154.37 Sun Jan 20 11:25:23 CET 2008
16 - soften the check for an active parser for perl 5.10 (avoiding
17 "Coro::State::transfer called while parsing" in many cases).
18
194.36 Sun Jan 13 10:53:56 CET 2008
20 - reset diehook when terminating from an async_pool as to not
21 trigger any __DIE__ handlers.
22
234.35 Sun Jan 13 04:14:13 CET 2008
24 - "bt" debug command now displays any exceptions
25 from longmess and also skips the innermost
26 stackframes, giving more useufl output.
27 - allow backtraces in coroutines blocked in Coro::EV,
28 at a <1% speed hit.
29 - handle localising of $SIG{__WARN__} and __DIE__
30 properly (with a proper amount of dirty hacking).
31
324.34 Sat Dec 22 17:49:53 CET 2007
33 - upgrade to EV version 2.0 API.
34
354.33 Mon Dec 17 08:36:12 CET 2007
36 - make Coro::AIO etc. loadable in the absence of EV.
37
384.32 Mon Dec 17 07:46:02 CET 2007
39 - majorly improved Coro::Handle's performance with Coro::EV.
40 - implemented the until now mythical Coro::BDB module.
41 - specialcase EV in Coro::AIO and Coro::BDB for extra speed.
42
434.31 Wed Dec 5 12:32:39 CET 2007
44 - remove warn statement form Coro::Util.
45
464.3 Tue Dec 4 20:33:14 CET 2007
47 - calls to the idle function could cause stack corruption
48 when the stack changed.
49 - do no longer rely on the presence of EV::DNS if EV is used
50 (because it is gone), but instead take avdantage of EV::ADNS
51 if available.
52 - add ($) prototypes to all functions in Coro::Storable.
53 - use a conventional (safer) idle callback in Coro::EV.
54 - do accept quickly in Coro::Debug to avoid endless loops.
55
564.22 Fri Nov 30 16:04:04 CET 2007
57 - really use optimised versions for Event and EV in Coro::Util
58 and Coro::Handle.
59
604.21 Sun Nov 25 10:48:59 CET 2007
61 - fix a spurious memory read.
62 - Coro::EV no longer keeps the eventloop "alive".
63
644.2 Fri Nov 9 20:47:05 CET 2007
65 - enable/disable tracing from a new coroutine, not a pooled one.
66 - fix a memleak in Coro::Event.
67 - removed killall call from fork_eval.
68 - made sure store_fd is already loaded so that fork_eval
69 does not have to parse autoload in each subprocess.
70 - only use assembly method if -O switch is in $Config{optimize}.
71 - add (optional) Coro::EV module, so far the best event loop module
72 directly supported by Coro.
73 - if the event model is EV, use EV::DNS to resolve
74 stuff in Coro::Util.
75 - don't get confused by multiple event notifications in Coro::Handle.
76 - initial support for EV (libevent interface).
77 - require Event and EV using configure_requires, to force their existance.
78
794.13 Wed Oct 24 07:26:45 CEST 2007
80 - add Coro::Storable::blocking_thaw.
81 - use a vastly more complicated technique to localise
82 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
83 - use a coroutine for the idle callback Coro::Event,
84 instead of running Event in the current coroutine context.
85 This also catches recursive invocations.
86 - actually report fork errors in gethostbyname and inet_aton.
87
884.11 Thu Oct 11 02:40:24 CEST 2007
89 - port to threaded perls.
90
914.1 Thu Oct 11 02:38:16 CEST 2007
92 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
93 be local to each coro (see Coro::State).
94 - incompatible change: for very deep reasons, cede and cede_notself
95 cannot return anything, so nothing will be returned.
96 - possibly bring back 5.10 compatibility (untested).
97 - work around stupid (and wrong) warning on 5.10 :(.
98 - overlay the saved state over the context stack. This saves
99 a few hundred bytes per coroutine on average and also
100 speeds up context switching a bit.
101 - further tune default stack sizes.
102 - (more) correctly calculate stack usage in coro_rss.
103 - Coro::Storable::blocking_* did not properly lock
104 resulting in races between coroutines.
105 - added Coro::Storable::guard.
106 - stopping to trace a coroutine could destroy the cctx of
107 an unrelated coroutine.
108 - explain the relationship between Perl and C coroutines in
109 more detail in Coro::State.
110 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
111 causing a fork per resolve. This also affected Coro::Socket.
112 - switch to a separate stack in $coro->call/eval to avoid
113 invalidating pointers.
114
1154.03 Sat Oct 6 21:24:00 CEST 2007
116 - added Coro::throw method.
117 - minor code cleanups.
118
1194.02 Sat Oct 6 02:36:47 CEST 2007
120 - fix a very minor per-coroutine memleak (a single codereference).
121 - fixed a bug where the currently in-use c context would be freed
122 prematurely (can happen only when programs change the stacksize
123 or use tracing).
124 - tracing can no longer keep a coro alive after it terminated.
125 - do static branch prediction in the common path for gcc. gives
126 about 2-5% speed improvement here.
127
1284.01 Fri Oct 5 22:10:49 CEST 2007
129 - instead of recreating *a* standard output handle we simply
130 use STDOUT, which is faster and hopefully more robust.
131
1324.0 Fri Oct 5 12:56:00 CEST 2007
133 - incompatibly changed Coro::Storable::freeze.
134 - major new feature: added Coro::Debug, for interactive coroutine
135 debugging, tracing and much more.
136 - major bug fix: unbelievable, but true: $_, $/ and many other
137 "saved" variables actually weren't being saved. This has been fixed,
138 of course, while increasing performance while losing all the save
139 flags.
140 - save flags are gone, and all the api functions dealing with them.
141 - added Coro::Semaphore::adjust.
142 - added Coro::Util::fork_eval.
143 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
144 - added Coro::killall.
145 - reduce initial stack sizes to allow for "micro-coroutines".
146 - better async_pool resource management, moved parts of async_pool
147 handling to XS (major speed improvement).
148 - actually croak before modifying important data structures.
149 - refuse to transfer while compiling.
150 - possibly support eval EXPR better now.
151 - enable assembly per default on linux+bsd x86+amd64.
152 - all internal members were renamed _something for easier subclassing.
153 - many minor tweaks.
154
1553.63 Wed May 16 14:10:06 CEST 2007
156 - implement handcoded assembly for x86/amd64 SVR ABI.
157
1583.62 Fri Apr 27 21:36:06 CEST 2007
159 - upgrade libcoro (which might set unwind info correctly).
160 - change default on linux to setjmp/longjmp.
161
1623.61 Thu Apr 19 12:36:18 CEST 2007
163 - Coro::Storable caused an endless loop when thawing invalid
164 pst's sometimes.
165 - use a Semaphore in Coro::Storable, as Storable doesn't
166 seem to be reentrant (although it is documented to
167 be threadsafe...).
168 - fix Coro::Signal to bring back the original unreliable
169 but stateful semantics.
170 - fixed a lot of typos in Coro.pm (patch submitted by David
171 Steinbrunner, which applied flawlessly).
172
1733.6 Sat Apr 14 17:13:31 CEST 2007
174 - added some bugfixes to get eg/myhttpd working again.
175 - added Coro::Storable for often-cede'ing freeze/thaw.
176 - try to do a clean exit when a coroutine calls exit
177 (EXPERIMENTAL).
178 - got rid of indirect call through _coro_init.
179 - updated the partly antique examples in eg/ to
180 work again and be a bit less magic, too.
181 - fixed Coro::Signal semantics to work as documented again.
182
1833.55 Sun Mar 25 01:20:47 CET 2007
184 - add SAVE_DEFFH to save the default filehandle and enable
185 it by default.
186 - finally move socket-operations from Coro::Socket to Coro::Handle
187 to be able to unblock foreign sockets.
188 - add Coro::State::save_also and guarded_save.
189 - add count accessor to Coro::Semaphore.
190 - add Coro::State::cctx_stacksize.
191 - just for the fun of it, do not rely on implicit context,
192 which can dramatically improve performance, but people
193 using windows-process-emulation perls do not care much about
194 performance.
195
1963.51 Sun Mar 4 14:18:04 CET 2007
197 - fixed a problem when you weakened references to Coro::State's
198 (patch by Yuval Kogman).
199
2003.501 Wed Feb 28 12:44:07 CET 2007
201 - rename some global symbols as macosx from hell redefines
202 them without asking.
203
2043.5 Tue Feb 13 20:22:53 CET 2007
7 - do AnyEvent model detection earlier, avoiding problems 205 - do AnyEvent model detection earlier, avoiding problems
