103.7 8 - fix a spurious memory read.
9 - Coro::EV no longer keeps the eventloop "alive".
10
114.2 Fri Nov 9 20:47:05 CET 2007
12 - enable/disable tracing from a new coroutine, not a pooled one.
13 - fix a memleak in Coro::Event.
14 - removed killall call from fork_eval.
15 - made sure store_fd is already loaded so that fork_eval
16 does not have to parse autoload in each subprocess.
17 - only use assembly method if -O switch is in $Config{optimize}.
18 - add (optional) Coro::EV module, so far the best event loop module
19 directly supported by Coro.
20 - if the event model is EV, use EV::DNS to resolve
21 stuff in Coro::Util.
22 - don't get confused by multiple event notifications in Coro::Handle.
23 - initial support for EV (libevent interface).
24 - require Event and EV using configure_requires, to force their existance.
25
264.13 Wed Oct 24 07:26:45 CEST 2007
27 - add Coro::Storable::blocking_thaw.
28 - use a vastly more complicated technique to localise
29 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
30 - use a coroutine for the idle callback Coro::Event,
31 instead of running Event in the current coroutine context.
32 This also catches recursive invocations.
33 - actually report fork errors in gethostbyname and inet_aton.
34
354.11 Thu Oct 11 02:40:24 CEST 2007
36 - port to threaded perls.
37
384.1 Thu Oct 11 02:38:16 CEST 2007
39 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
40 be local to each coro (see Coro::State).
41 - incompatible change: for very deep reasons, cede and cede_notself
42 cannot return anything, so nothing will be returned.
43 - possibly bring back 5.10 compatibility (untested).
44 - work around stupid (and wrong) warning on 5.10 :(.
45 - overlay the saved state over the context stack. This saves
46 a few hundred bytes per coroutine on average and also
47 speeds up context switching a bit.
48 - further tune default stack sizes.
49 - (more) correctly calculate stack usage in coro_rss.
50 - Coro::Storable::blocking_* did not properly lock
51 resulting in races between coroutines.
52 - added Coro::Storable::guard.
53 - stopping to trace a coroutine could destroy the cctx of
54 an unrelated coroutine.
55 - explain the relationship between Perl and C coroutines in
56 more detail in Coro::State.
57 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
58 causing a fork per resolve. This also affected Coro::Socket.
59 - switch to a separate stack in $coro->call/eval to avoid
60 invalidating pointers.
61
624.03 Sat Oct 6 21:24:00 CEST 2007
63 - added Coro::throw method.
64 - minor code cleanups.
65
664.02 Sat Oct 6 02:36:47 CEST 2007
67 - fix a very minor per-coroutine memleak (a single codereference).
68 - fixed a bug where the currently in-use c context would be freed
69 prematurely (can happen only when programs change the stacksize
70 or use tracing).
71 - tracing can no longer keep a coro alive after it terminated.
72 - do static branch prediction in the common path for gcc. gives
73 about 2-5% speed improvement here.
74
754.01 Fri Oct 5 22:10:49 CEST 2007
76 - instead of recreating *a* standard output handle we simply
77 use STDOUT, which is faster and hopefully more robust.
78
794.0 Fri Oct 5 12:56:00 CEST 2007
11 - incompatibly changed Coro::Storable::freeze. 80 - incompatibly changed Coro::Storable::freeze.
12 - added Coro::Debug, interactive coroutine debugging. 81 - major new feature: added Coro::Debug, for interactive coroutine
82 debugging, tracing and much more.
83 - major bug fix: unbelievable, but true: $_, $/ and many other
84 "saved" variables actually weren't being saved. This has been fixed,
85 of course, while increasing performance while losing all the save
86 flags.
87 - save flags are gone, and all the api functions dealing with them.
13 - added Coro::Semaphore::adjust. 88 - added Coro::Semaphore::adjust.
14 - added Coro::Util::fork_eval. 89 - added Coro::Util::fork_eval.
15 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}. 90 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
91 - added Coro::killall.
16 - reduce initial stack sizes to allow for "micro-coroutines". 92 - reduce initial stack sizes to allow for "micro-coroutines".
17 - better async_pool resource management, moved parts of async_pool 93 - better async_pool resource management, moved parts of async_pool
18 handling to XS (major speed improvement). 94 handling to XS (major speed improvement).
95 - actually croak before modifying important data structures.
96 - refuse to transfer while compiling.
97 - possibly support eval EXPR better now.
98 - enable assembly per default on linux+bsd x86+amd64.
99 - all internal members were renamed _something for easier subclassing.
19 - many minor tweaks. 100 - many minor tweaks.

22 - implement handcoded assembly for x86/amd64 SVR ABI. 103 - implement handcoded assembly for x86/amd64 SVR ABI.
