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)).

63.52 84.36 Sun Jan 13 10:53:56 CET 2008
9 - reset diehook when terminating from an async_pool as to not
10 trigger any __DIE__ handlers.
11
124.35 Sun Jan 13 04:14:13 CET 2008
13 - "bt" debug command now displays any exceptions
14 from longmess and also skips the innermost
15 stackframes, giving more useufl output.
16 - allow backtraces in coroutines blocked in Coro::EV,
17 at a <1% speed hit.
18 - handle localising of $SIG{__WARN__} and __DIE__
19 properly (with a proper amount of dirty hacking).
20
214.34 Sat Dec 22 17:49:53 CET 2007
22 - upgrade to EV version 2.0 API.
23
244.33 Mon Dec 17 08:36:12 CET 2007
25 - make Coro::AIO etc. loadable in the absence of EV.
26
274.32 Mon Dec 17 07:46:02 CET 2007
28 - majorly improved Coro::Handle's performance with Coro::EV.
29 - implemented the until now mythical Coro::BDB module.
30 - specialcase EV in Coro::AIO and Coro::BDB for extra speed.
31
324.31 Wed Dec 5 12:32:39 CET 2007
33 - remove warn statement form Coro::Util.
34
354.3 Tue Dec 4 20:33:14 CET 2007
36 - calls to the idle function could cause stack corruption
37 when the stack changed.
38 - do no longer rely on the presence of EV::DNS if EV is used
39 (because it is gone), but instead take avdantage of EV::ADNS
40 if available.
41 - add ($) prototypes to all functions in Coro::Storable.
42 - use a conventional (safer) idle callback in Coro::EV.
43 - do accept quickly in Coro::Debug to avoid endless loops.
44
454.22 Fri Nov 30 16:04:04 CET 2007
46 - really use optimised versions for Event and EV in Coro::Util
47 and Coro::Handle.
48
494.21 Sun Nov 25 10:48:59 CET 2007
50 - fix a spurious memory read.
51 - Coro::EV no longer keeps the eventloop "alive".
52
534.2 Fri Nov 9 20:47:05 CET 2007
54 - enable/disable tracing from a new coroutine, not a pooled one.
55 - fix a memleak in Coro::Event.
56 - removed killall call from fork_eval.
57 - made sure store_fd is already loaded so that fork_eval
58 does not have to parse autoload in each subprocess.
59 - only use assembly method if -O switch is in $Config{optimize}.
60 - add (optional) Coro::EV module, so far the best event loop module
61 directly supported by Coro.
62 - if the event model is EV, use EV::DNS to resolve
63 stuff in Coro::Util.
64 - don't get confused by multiple event notifications in Coro::Handle.
65 - initial support for EV (libevent interface).
66 - require Event and EV using configure_requires, to force their existance.
67
684.13 Wed Oct 24 07:26:45 CEST 2007
69 - add Coro::Storable::blocking_thaw.
70 - use a vastly more complicated technique to localise
71 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
72 - use a coroutine for the idle callback Coro::Event,
73 instead of running Event in the current coroutine context.
74 This also catches recursive invocations.
75 - actually report fork errors in gethostbyname and inet_aton.
76
774.11 Thu Oct 11 02:40:24 CEST 2007
78 - port to threaded perls.
79
804.1 Thu Oct 11 02:38:16 CEST 2007
81 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
82 be local to each coro (see Coro::State).
83 - incompatible change: for very deep reasons, cede and cede_notself
84 cannot return anything, so nothing will be returned.
85 - possibly bring back 5.10 compatibility (untested).
86 - work around stupid (and wrong) warning on 5.10 :(.
87 - overlay the saved state over the context stack. This saves
88 a few hundred bytes per coroutine on average and also
89 speeds up context switching a bit.
90 - further tune default stack sizes.
91 - (more) correctly calculate stack usage in coro_rss.
92 - Coro::Storable::blocking_* did not properly lock
93 resulting in races between coroutines.
94 - added Coro::Storable::guard.
95 - stopping to trace a coroutine could destroy the cctx of
96 an unrelated coroutine.
97 - explain the relationship between Perl and C coroutines in
98 more detail in Coro::State.
99 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
100 causing a fork per resolve. This also affected Coro::Socket.
101 - switch to a separate stack in $coro->call/eval to avoid
102 invalidating pointers.
103
1044.03 Sat Oct 6 21:24:00 CEST 2007
105 - added Coro::throw method.
106 - minor code cleanups.
107
1084.02 Sat Oct 6 02:36:47 CEST 2007
109 - fix a very minor per-coroutine memleak (a single codereference).
110 - fixed a bug where the currently in-use c context would be freed
111 prematurely (can happen only when programs change the stacksize
112 or use tracing).
113 - tracing can no longer keep a coro alive after it terminated.
114 - do static branch prediction in the common path for gcc. gives
115 about 2-5% speed improvement here.
116
1174.01 Fri Oct 5 22:10:49 CEST 2007
118 - instead of recreating *a* standard output handle we simply
119 use STDOUT, which is faster and hopefully more robust.
120
1214.0 Fri Oct 5 12:56:00 CEST 2007
122 - incompatibly changed Coro::Storable::freeze.
123 - major new feature: added Coro::Debug, for interactive coroutine
124 debugging, tracing and much more.
125 - major bug fix: unbelievable, but true: $_, $/ and many other
126 "saved" variables actually weren't being saved. This has been fixed,
127 of course, while increasing performance while losing all the save
128 flags.
129 - save flags are gone, and all the api functions dealing with them.
130 - added Coro::Semaphore::adjust.
131 - added Coro::Util::fork_eval.
132 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
133 - added Coro::killall.
134 - reduce initial stack sizes to allow for "micro-coroutines".
135 - better async_pool resource management, moved parts of async_pool
136 handling to XS (major speed improvement).
137 - actually croak before modifying important data structures.
138 - refuse to transfer while compiling.
139 - possibly support eval EXPR better now.
140 - enable assembly per default on linux+bsd x86+amd64.
141 - all internal members were renamed _something for easier subclassing.
142 - many minor tweaks.
143
1443.63 Wed May 16 14:10:06 CEST 2007
145 - implement handcoded assembly for x86/amd64 SVR ABI.
146
1473.62 Fri Apr 27 21:36:06 CEST 2007
148 - upgrade libcoro (which might set unwind info correctly).
149 - change default on linux to setjmp/longjmp.
150
1513.61 Thu Apr 19 12:36:18 CEST 2007
152 - Coro::Storable caused an endless loop when thawing invalid
153 pst's sometimes.
154 - use a Semaphore in Coro::Storable, as Storable doesn't
155 seem to be reentrant (although it is documented to
156 be threadsafe...).
157 - fix Coro::Signal to bring back the original unreliable
158 but stateful semantics.
159 - fixed a lot of typos in Coro.pm (patch submitted by David
160 Steinbrunner, which applied flawlessly).
161
1623.6 Sat Apr 14 17:13:31 CEST 2007
163 - added some bugfixes to get eg/myhttpd working again.
164 - added Coro::Storable for often-cede'ing freeze/thaw.
165 - try to do a clean exit when a coroutine calls exit
166 (EXPERIMENTAL).
167 - got rid of indirect call through _coro_init.
168 - updated the partly antique examples in eg/ to
169 work again and be a bit less magic, too.
170 - fixed Coro::Signal semantics to work as documented again.
171
1723.55 Sun Mar 25 01:20:47 CET 2007
173 - add SAVE_DEFFH to save the default filehandle and enable
174 it by default.
175 - finally move socket-operations from Coro::Socket to Coro::Handle
176 to be able to unblock foreign sockets.
177 - add Coro::State::save_also and guarded_save.
7 - add count accessor to Coro::Semaphore. 178 - add count accessor to Coro::Semaphore.
8 - add Coro::State::cctx_stacksize. 179 - add Coro::State::cctx_stacksize.
9 - just for the fun of it, do not rely on implicit context, 180 - just for the fun of it, do not rely on implicit context,
10 which can dramatically improve performance, but people 181 which can dramatically improve performance, but people
11 using windows-process-emulation perls do not care much about 182 using windows-process-emulation perls do not care much about
12 performance. 183 performance.
13 - finally move socket-operations from Coro::Socket to Coro::Handle
14 to be able to unblock foreign sockets.
15 184
163.51 Sun Mar 4 14:18:04 CET 2007 1853.51 Sun Mar 4 14:18:04 CET 2007
17 - fixed a problem when you weakened references to Coro::State's 186 - fixed a problem when you weakened references to Coro::State's
