103.8 84.21 Sun Nov 25 10:48:59 CET 2007
9 - fix a spurious memory read.
10 - Coro::EV no longer keeps the eventloop "alive".
11
124.2 Fri Nov 9 20:47:05 CET 2007
13 - enable/disable tracing from a new coroutine, not a pooled one.
14 - fix a memleak in Coro::Event.
15 - removed killall call from fork_eval.
16 - made sure store_fd is already loaded so that fork_eval
17 does not have to parse autoload in each subprocess.
18 - only use assembly method if -O switch is in $Config{optimize}.
19 - add (optional) Coro::EV module, so far the best event loop module
20 directly supported by Coro.
21 - if the event model is EV, use EV::DNS to resolve
22 stuff in Coro::Util.
23 - don't get confused by multiple event notifications in Coro::Handle.
24 - initial support for EV (libevent interface).
25 - require Event and EV using configure_requires, to force their existance.
26
274.13 Wed Oct 24 07:26:45 CEST 2007
28 - add Coro::Storable::blocking_thaw.
29 - use a vastly more complicated technique to localise
30 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
31 - use a coroutine for the idle callback Coro::Event,
32 instead of running Event in the current coroutine context.
33 This also catches recursive invocations.
34 - actually report fork errors in gethostbyname and inet_aton.
35
364.11 Thu Oct 11 02:40:24 CEST 2007
37 - port to threaded perls.
38
394.1 Thu Oct 11 02:38:16 CEST 2007
40 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
41 be local to each coro (see Coro::State).
42 - incompatible change: for very deep reasons, cede and cede_notself
43 cannot return anything, so nothing will be returned.
44 - possibly bring back 5.10 compatibility (untested).
45 - work around stupid (and wrong) warning on 5.10 :(.
46 - overlay the saved state over the context stack. This saves
47 a few hundred bytes per coroutine on average and also
48 speeds up context switching a bit.
49 - further tune default stack sizes.
50 - (more) correctly calculate stack usage in coro_rss.
51 - Coro::Storable::blocking_* did not properly lock
52 resulting in races between coroutines.
53 - added Coro::Storable::guard.
54 - stopping to trace a coroutine could destroy the cctx of
55 an unrelated coroutine.
56 - explain the relationship between Perl and C coroutines in
57 more detail in Coro::State.
58 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
59 causing a fork per resolve. This also affected Coro::Socket.
60 - switch to a separate stack in $coro->call/eval to avoid
61 invalidating pointers.
62
634.03 Sat Oct 6 21:24:00 CEST 2007
64 - added Coro::throw method.
65 - minor code cleanups.
66
674.02 Sat Oct 6 02:36:47 CEST 2007
68 - fix a very minor per-coroutine memleak (a single codereference).
69 - fixed a bug where the currently in-use c context would be freed
70 prematurely (can happen only when programs change the stacksize
71 or use tracing).
72 - tracing can no longer keep a coro alive after it terminated.
73 - do static branch prediction in the common path for gcc. gives
74 about 2-5% speed improvement here.
75
764.01 Fri Oct 5 22:10:49 CEST 2007
77 - instead of recreating *a* standard output handle we simply
78 use STDOUT, which is faster and hopefully more robust.

804.0 Fri Oct 5 12:56:00 CEST 2007
11 - incompatibly changed Coro::Storable::freeze. 81 - incompatibly changed Coro::Storable::freeze.
12 - major new feature: added Coro::Debug, for interactive coroutine 82 - major new feature: added Coro::Debug, for interactive coroutine
13 debugging, tracing and much more. 83 debugging, tracing and much more.
84 - major bug fix: unbelievable, but true: $_, $/ and many other
85 "saved" variables actually weren't being saved. This has been fixed,
86 of course, while increasing performance while losing all the save
87 flags.
88 - save flags are gone, and all the api functions dealing with them.
14 - added Coro::Semaphore::adjust. 89 - added Coro::Semaphore::adjust.
15 - added Coro::Util::fork_eval. 90 - added Coro::Util::fork_eval.
16 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}. 91 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
92 - added Coro::killall.
17 - reduce initial stack sizes to allow for "micro-coroutines". 93 - reduce initial stack sizes to allow for "micro-coroutines".
18 - better async_pool resource management, moved parts of async_pool 94 - better async_pool resource management, moved parts of async_pool
19 handling to XS (major speed improvement). 95 handling to XS (major speed improvement).
96 - actually croak before modifying important data structures.
97 - refuse to transfer while compiling.
98 - possibly support eval EXPR better now.
99 - enable assembly per default on linux+bsd x86+amd64.
100 - all internal members were renamed _something for easier subclassing.
20 - many minor tweaks. 101 - many minor tweaks.
