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)).

84.11 Thu Oct 11 02:40:24 CEST 2007
9 - port to threaded perls.
10
114.1 Thu Oct 11 02:38:16 CEST 2007
12 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
13 be local to each coro (see Coro::State).
14 - incompatible change: for very deep reasons, cede and cede_notself
15 cannot return anything, so nothing will be returned.
16 - possibly bring back 5.10 compatibility (untested).
17 - work around stupid (and wrong) warning on 5.10 :(.
18 - overlay the saved state over the context stack. This saves
19 a few hundred bytes per coroutine on average and also
20 speeds up context switching a bit.
21 - further tune default stack sizes.
22 - (more) correctly calculate stack usage in coro_rss.
23 - Coro::Storable::blocking_* did not properly lock
24 resulting in races between coroutines.
25 - added Coro::Storable::guard.
26 - stopping to trace a coroutine could destroy the cctx of
27 an unrelated coroutine.
28 - explain the relationship between Perl and C coroutines in
29 more detail in Coro::State.
30 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
31 causing a fork per resolve. This also affected Coro::Socket.
32 - switch to a separate stack in $coro->call/eval to avoid
33 invalidating pointers.
34
354.03 Sat Oct 6 21:24:00 CEST 2007
36 - added Coro::throw method.
37 - minor code cleanups.
38
394.02 Sat Oct 6 02:36:47 CEST 2007
40 - fix a very minor per-coroutine memleak (a single codereference).
41 - fixed a bug where the currently in-use c context would be freed
42 prematurely (can happen only when programs change the stacksize
43 or use tracing).
44 - tracing can no longer keep a coro alive after it terminated.
45 - do static branch prediction in the common path for gcc. gives
46 about 2-5% speed improvement here.
47
484.01 Fri Oct 5 22:10:49 CEST 2007
49 - instead of recreating *a* standard output handle we simply
50 use STDOUT, which is faster and hopefully more robust.
51
524.0 Fri Oct 5 12:56:00 CEST 2007
53 - incompatibly changed Coro::Storable::freeze.
54 - major new feature: added Coro::Debug, for interactive coroutine
55 debugging, tracing and much more.
56 - major bug fix: unbelievable, but true: $_, $/ and many other
57 "saved" variables actually weren't being saved. This has been fixed,
58 of course, while increasing performance while losing all the save
59 flags.
60 - save flags are gone, and all the api functions dealing with them.
61 - added Coro::Semaphore::adjust.
62 - added Coro::Util::fork_eval.
63 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
64 - added Coro::killall.
65 - reduce initial stack sizes to allow for "micro-coroutines".
66 - better async_pool resource management, moved parts of async_pool
67 handling to XS (major speed improvement).
68 - actually croak before modifying important data structures.
69 - refuse to transfer while compiling.
70 - possibly support eval EXPR better now.
71 - enable assembly per default on linux+bsd x86+amd64.
72 - all internal members were renamed _something for easier subclassing.
73 - many minor tweaks.
74
753.63 Wed May 16 14:10:06 CEST 2007
76 - implement handcoded assembly for x86/amd64 SVR ABI.
77
783.62 Fri Apr 27 21:36:06 CEST 2007
79 - upgrade libcoro (which might set unwind info correctly).
80 - change default on linux to setjmp/longjmp.
81
823.61 Thu Apr 19 12:36:18 CEST 2007
83 - Coro::Storable caused an endless loop when thawing invalid
84 pst's sometimes.
85 - use a Semaphore in Coro::Storable, as Storable doesn't
86 seem to be reentrant (although it is documented to
87 be threadsafe...).
88 - fix Coro::Signal to bring back the original unreliable
89 but stateful semantics.
90 - fixed a lot of typos in Coro.pm (patch submitted by David
91 Steinbrunner, which applied flawlessly).
92
933.6 Sat Apr 14 17:13:31 CEST 2007
94 - added some bugfixes to get eg/myhttpd working again.
95 - added Coro::Storable for often-cede'ing freeze/thaw.
96 - try to do a clean exit when a coroutine calls exit
97 (EXPERIMENTAL).
98 - got rid of indirect call through _coro_init.
99 - updated the partly antique examples in eg/ to
100 work again and be a bit less magic, too.
101 - fixed Coro::Signal semantics to work as documented again.
102
1033.55 Sun Mar 25 01:20:47 CET 2007
104 - add SAVE_DEFFH to save the default filehandle and enable
105 it by default.
106 - finally move socket-operations from Coro::Socket to Coro::Handle
107 to be able to unblock foreign sockets.
108 - add Coro::State::save_also and guarded_save.
109 - add count accessor to Coro::Semaphore.
110 - add Coro::State::cctx_stacksize.
111 - just for the fun of it, do not rely on implicit context,
112 which can dramatically improve performance, but people
113 using windows-process-emulation perls do not care much about
114 performance.
115
1163.51 Sun Mar 4 14:18:04 CET 2007
117 - fixed a problem when you weakened references to Coro::State's
118 (patch by Yuval Kogman).
119
1203.501 Wed Feb 28 12:44:07 CET 2007
121 - rename some global symbols as macosx from hell redefines
122 them without asking.
123
1243.5 Tue Feb 13 20:22:53 CET 2007
125 - do AnyEvent model detection earlier, avoiding problems
126 caused by first using AnyEvent and later Coro::Event.
127 - implement and document Coro::Event event objects.
128 - fix a potential problem in Coro::Event causing crashes.
129 - initialise PL_comppad when creating a new coroutine,
130 avoids crashes on early coro destruction.
131
1323.41 Mon Jan 22 19:19:49 CET 2007
133 - readline on Coro::Handle did not support undefined $/,
134 nor did it deliver partial lines on EOF or error.
135 - implement malloc fallback for stack allocation because
136 stupid broken idiotic OSX has a stupid broken
137 idiotic fits-the-whole-os mmap "implementation" and
138 my dick feels longer if Coro is portable even to
139 obsolete platforms.
140
1413.4 Fri Jan 19 21:52:54 CET 2007
6 - remove t/09_timer.t, as it isn't really testing much 142 - remove t/09_timer.t, as it isn't really testing much
7 but was rather flaky in practise. 143 but was rather flaky in practise.
144 - async_pool coro would keep arguments and callback alive until
145 it was reused.
146 - cancellation of a coroutine could cause spurious idle calls
147 in cede_notself.

11 - Coro::Event blocking semantics have been changed, 151 - Coro::Event blocking semantics have been changed,
12 documented and - hopefully - improved. 152 documented and - hopefully - improved.
