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 84.1
9 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
10 be local to each coro (see Coro::State).
11 - possibly bring back 5.10 compatibility (untested).
12 - work around stupid (and wrong) warning on 5.10 :(.
13 - overlay the saved state over the context stack. This saves
14 a few hundred bytes per coroutine on average and also
15 speeds up context switching a bit.
16 - further tune default stack sizes.
17 - (more) correctly calculate stack usage in coro_rss.
18 - Coro::Storable::blocking_* did not properly lock
19 resulting in races between coroutines.
20 - added Coro::Storable::guard.
21 - stopping to trace a coroutine could destroy the cctx of
22 an unrelated coroutine.
23 - explain the relationship between Perl and C coroutines in
24 more detail in Coro::State.
25 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
26 causing a fork per resolve. This also affected Coro::Socket.
27 - sped up Coro::Event next event handling by 15%, uses less memory.
28 - switch to a separate stack in $coro->call/eval to avoid
29 invalidating pointers.
30
314.03 Sat Oct 6 21:24:00 CEST 2007
32 - added Coro::throw method.
33 - minor code cleanups.
34
354.02 Sat Oct 6 02:36:47 CEST 2007
36 - fix a very minor per-coroutine memleak (a single codereference).
37 - fixed a bug where the currently in-use c context would be freed
38 prematurely (can happen only when programs change the stacksize
39 or use tracing).
40 - tracing can no longer keep a coro alive after it terminated.
41 - do static branch prediction in the common path for gcc. gives
42 about 2-5% speed improvement here.
43
444.01 Fri Oct 5 22:10:49 CEST 2007
45 - instead of recreating *a* standard output handle we simply
46 use STDOUT, which is faster and hopefully more robust.
47
484.0 Fri Oct 5 12:56:00 CEST 2007
49 - incompatibly changed Coro::Storable::freeze.
50 - major new feature: added Coro::Debug, for interactive coroutine
51 debugging, tracing and much more.
52 - major bug fix: unbelievable, but true: $_, $/ and many other
53 "saved" variables actually weren't being saved. This has been fixed,
54 of course, while increasing performance while losing all the save
55 flags.
56 - save flags are gone, and all the api functions dealing with them.
57 - added Coro::Semaphore::adjust.
58 - added Coro::Util::fork_eval.
59 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
60 - added Coro::killall.
61 - reduce initial stack sizes to allow for "micro-coroutines".
62 - better async_pool resource management, moved parts of async_pool
63 handling to XS (major speed improvement).
64 - actually croak before modifying important data structures.
65 - refuse to transfer while compiling.
66 - possibly support eval EXPR better now.
67 - enable assembly per default on linux+bsd x86+amd64.
68 - all internal members were renamed _something for easier subclassing.
69 - many minor tweaks.
70
713.63 Wed May 16 14:10:06 CEST 2007
72 - implement handcoded assembly for x86/amd64 SVR ABI.
73
743.62 Fri Apr 27 21:36:06 CEST 2007
75 - upgrade libcoro (which might set unwind info correctly).
76 - change default on linux to setjmp/longjmp.
77
783.61 Thu Apr 19 12:36:18 CEST 2007
79 - Coro::Storable caused an endless loop when thawing invalid
80 pst's sometimes.
81 - use a Semaphore in Coro::Storable, as Storable doesn't
82 seem to be reentrant (although it is documented to
83 be threadsafe...).
84 - fix Coro::Signal to bring back the original unreliable
85 but stateful semantics.
86 - fixed a lot of typos in Coro.pm (patch submitted by David
87 Steinbrunner, which applied flawlessly).
88
893.6 Sat Apr 14 17:13:31 CEST 2007
90 - added some bugfixes to get eg/myhttpd working again.
91 - added Coro::Storable for often-cede'ing freeze/thaw.
92 - try to do a clean exit when a coroutine calls exit
93 (EXPERIMENTAL).
94 - got rid of indirect call through _coro_init.
95 - updated the partly antique examples in eg/ to
96 work again and be a bit less magic, too.
97 - fixed Coro::Signal semantics to work as documented again.
98
993.55 Sun Mar 25 01:20:47 CET 2007
100 - add SAVE_DEFFH to save the default filehandle and enable
101 it by default.
102 - finally move socket-operations from Coro::Socket to Coro::Handle
103 to be able to unblock foreign sockets.
104 - add Coro::State::save_also and guarded_save.
7 - add count accessor to Coro::Semaphore. 105 - add count accessor to Coro::Semaphore.
8 - add Coro::State::cctx_stacksize. 106 - add Coro::State::cctx_stacksize.
9 - just for the fun of it, do not rely on implicit context, 107 - just for the fun of it, do not rely on implicit context,
10 which can dramatically improve performance, but people 108 which can dramatically improve performance, but people
