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)).

84.3 Tue Dec 4 20:33:14 CET 2007
9 - calls to the idle function could cause stack corruption
10 when the stack changed.
11 - do no longer rely on the presence of EV::DNS if EV is used
12 (because it is gone), but instead take avdantage of EV::ADNS
13 if available.
14 - add ($) prototypes to all functions in Coro::Storable.
15 - use a conventional (safer) idle callback in Coro::EV.
16 - do accept quickly in Coro::Debug to avoid endless loops.
17
184.22 Fri Nov 30 16:04:04 CET 2007
19 - really use optimised versions for Event and EV in Coro::Util
20 and Coro::Handle.
21
224.21 Sun Nov 25 10:48:59 CET 2007
23 - fix a spurious memory read.
24 - Coro::EV no longer keeps the eventloop "alive".
25
264.2 Fri Nov 9 20:47:05 CET 2007
27 - enable/disable tracing from a new coroutine, not a pooled one.
28 - fix a memleak in Coro::Event.
29 - removed killall call from fork_eval.
30 - made sure store_fd is already loaded so that fork_eval
31 does not have to parse autoload in each subprocess.
32 - only use assembly method if -O switch is in $Config{optimize}.
33 - add (optional) Coro::EV module, so far the best event loop module
34 directly supported by Coro.
35 - if the event model is EV, use EV::DNS to resolve
36 stuff in Coro::Util.
37 - don't get confused by multiple event notifications in Coro::Handle.
38 - initial support for EV (libevent interface).
39 - require Event and EV using configure_requires, to force their existance.
40
414.13 Wed Oct 24 07:26:45 CEST 2007
42 - add Coro::Storable::blocking_thaw.
43 - use a vastly more complicated technique to localise
44 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
45 - use a coroutine for the idle callback Coro::Event,
46 instead of running Event in the current coroutine context.
47 This also catches recursive invocations.
48 - actually report fork errors in gethostbyname and inet_aton.
49
504.11 Thu Oct 11 02:40:24 CEST 2007
51 - port to threaded perls.
52
534.1 Thu Oct 11 02:38:16 CEST 2007
54 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
55 be local to each coro (see Coro::State).
56 - incompatible change: for very deep reasons, cede and cede_notself
57 cannot return anything, so nothing will be returned.
58 - possibly bring back 5.10 compatibility (untested).
59 - work around stupid (and wrong) warning on 5.10 :(.
60 - overlay the saved state over the context stack. This saves
61 a few hundred bytes per coroutine on average and also
62 speeds up context switching a bit.
63 - further tune default stack sizes.
64 - (more) correctly calculate stack usage in coro_rss.
65 - Coro::Storable::blocking_* did not properly lock
66 resulting in races between coroutines.
67 - added Coro::Storable::guard.
68 - stopping to trace a coroutine could destroy the cctx of
69 an unrelated coroutine.
70 - explain the relationship between Perl and C coroutines in
71 more detail in Coro::State.
72 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
73 causing a fork per resolve. This also affected Coro::Socket.
74 - switch to a separate stack in $coro->call/eval to avoid
75 invalidating pointers.
76
774.03 Sat Oct 6 21:24:00 CEST 2007
78 - added Coro::throw method.
79 - minor code cleanups.
80
814.02 Sat Oct 6 02:36:47 CEST 2007
82 - fix a very minor per-coroutine memleak (a single codereference).
83 - fixed a bug where the currently in-use c context would be freed
84 prematurely (can happen only when programs change the stacksize
85 or use tracing).
86 - tracing can no longer keep a coro alive after it terminated.
87 - do static branch prediction in the common path for gcc. gives
88 about 2-5% speed improvement here.
89
904.01 Fri Oct 5 22:10:49 CEST 2007
91 - instead of recreating *a* standard output handle we simply
92 use STDOUT, which is faster and hopefully more robust.
93
944.0 Fri Oct 5 12:56:00 CEST 2007
95 - incompatibly changed Coro::Storable::freeze.
96 - major new feature: added Coro::Debug, for interactive coroutine
97 debugging, tracing and much more.
98 - major bug fix: unbelievable, but true: $_, $/ and many other
99 "saved" variables actually weren't being saved. This has been fixed,
100 of course, while increasing performance while losing all the save
101 flags.
102 - save flags are gone, and all the api functions dealing with them.
103 - added Coro::Semaphore::adjust.
104 - added Coro::Util::fork_eval.
105 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
106 - added Coro::killall.
107 - reduce initial stack sizes to allow for "micro-coroutines".
108 - better async_pool resource management, moved parts of async_pool
109 handling to XS (major speed improvement).
110 - actually croak before modifying important data structures.
111 - refuse to transfer while compiling.
112 - possibly support eval EXPR better now.
113 - enable assembly per default on linux+bsd x86+amd64.
114 - all internal members were renamed _something for easier subclassing.
115 - many minor tweaks.
116
1173.63 Wed May 16 14:10:06 CEST 2007
118 - implement handcoded assembly for x86/amd64 SVR ABI.
119
1203.62 Fri Apr 27 21:36:06 CEST 2007
121 - upgrade libcoro (which might set unwind info correctly).
122 - change default on linux to setjmp/longjmp.
123
1243.61 Thu Apr 19 12:36:18 CEST 2007
125 - Coro::Storable caused an endless loop when thawing invalid
126 pst's sometimes.
127 - use a Semaphore in Coro::Storable, as Storable doesn't
128 seem to be reentrant (although it is documented to
129 be threadsafe...).
130 - fix Coro::Signal to bring back the original unreliable
131 but stateful semantics.
132 - fixed a lot of typos in Coro.pm (patch submitted by David
133 Steinbrunner, which applied flawlessly).
134
1353.6 Sat Apr 14 17:13:31 CEST 2007
136 - added some bugfixes to get eg/myhttpd working again.
137 - added Coro::Storable for often-cede'ing freeze/thaw.
138 - try to do a clean exit when a coroutine calls exit
139 (EXPERIMENTAL).
140 - got rid of indirect call through _coro_init.
141 - updated the partly antique examples in eg/ to
142 work again and be a bit less magic, too.
143 - fixed Coro::Signal semantics to work as documented again.
144
1453.55 Sun Mar 25 01:20:47 CET 2007
146 - add SAVE_DEFFH to save the default filehandle and enable
147 it by default.
148 - finally move socket-operations from Coro::Socket to Coro::Handle
149 to be able to unblock foreign sockets.
150 - add Coro::State::save_also and guarded_save.
151 - add count accessor to Coro::Semaphore.
152 - add Coro::State::cctx_stacksize.
153 - just for the fun of it, do not rely on implicit context,
154 which can dramatically improve performance, but people
155 using windows-process-emulation perls do not care much about
156 performance.
157
1583.51 Sun Mar 4 14:18:04 CET 2007
159 - fixed a problem when you weakened references to Coro::State's
160 (patch by Yuval Kogman).
161
1623.501 Wed Feb 28 12:44:07 CET 2007
163 - rename some global symbols as macosx from hell redefines
164 them without asking.
5 165
63.5 Tue Feb 13 20:22:53 CET 2007 1663.5 Tue Feb 13 20:22:53 CET 2007
7 - do AnyEvent model detection earlier, avoiding problems 167 - do AnyEvent model detection earlier, avoiding problems
8 caused by first using AnyEvent and later Coro::Event. 168 caused by first using AnyEvent and later Coro::Event.
9 - implement and document Coro::Event event objects. 169 - implement and document Coro::Event event objects.
