103.7 84.2 Fri Nov 9 20:47:05 CET 2007
9 - enable/disable tracing from a new coroutine, not a pooled one.
10 - fix a memleak in Coro::Event.
11 - removed killall call from fork_eval.
12 - made sure store_fd is already loaded so that fork_eval
13 does not have to parse autoload in each subprocess.
14 - only use assembly method if -O switch is in $Config{optimize}.
15 - add (optional) Coro::EV module, so far the best event loop module
16 directly supported by Coro.
17 - if the event model is EV, use EV::DNS to resolve
18 stuff in Coro::Util.
19 - don't get confused by multiple event notifications in Coro::Handle.
20 - initial support for EV (libevent interface).
21 - require Event and EV using configure_requires, to force their existance.
22
234.13 Wed Oct 24 07:26:45 CEST 2007
24 - add Coro::Storable::blocking_thaw.
25 - use a vastly more complicated technique to localise
26 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
27 - use a coroutine for the idle callback Coro::Event,
28 instead of running Event in the current coroutine context.
29 This also catches recursive invocations.
30 - actually report fork errors in gethostbyname and inet_aton.
31
324.11 Thu Oct 11 02:40:24 CEST 2007
33 - port to threaded perls.
34
354.1 Thu Oct 11 02:38:16 CEST 2007
36 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
37 be local to each coro (see Coro::State).
38 - incompatible change: for very deep reasons, cede and cede_notself
39 cannot return anything, so nothing will be returned.
40 - possibly bring back 5.10 compatibility (untested).
41 - work around stupid (and wrong) warning on 5.10 :(.
42 - overlay the saved state over the context stack. This saves
43 a few hundred bytes per coroutine on average and also
44 speeds up context switching a bit.
45 - further tune default stack sizes.
46 - (more) correctly calculate stack usage in coro_rss.
47 - Coro::Storable::blocking_* did not properly lock
48 resulting in races between coroutines.
49 - added Coro::Storable::guard.
50 - stopping to trace a coroutine could destroy the cctx of
51 an unrelated coroutine.
52 - explain the relationship between Perl and C coroutines in
53 more detail in Coro::State.
54 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
55 causing a fork per resolve. This also affected Coro::Socket.
56 - switch to a separate stack in $coro->call/eval to avoid
57 invalidating pointers.
58
594.03 Sat Oct 6 21:24:00 CEST 2007
60 - added Coro::throw method.
61 - minor code cleanups.
62
634.02 Sat Oct 6 02:36:47 CEST 2007
64 - fix a very minor per-coroutine memleak (a single codereference).
65 - fixed a bug where the currently in-use c context would be freed
66 prematurely (can happen only when programs change the stacksize
67 or use tracing).
68 - tracing can no longer keep a coro alive after it terminated.
69 - do static branch prediction in the common path for gcc. gives
70 about 2-5% speed improvement here.
71
724.01 Fri Oct 5 22:10:49 CEST 2007
73 - instead of recreating *a* standard output handle we simply
74 use STDOUT, which is faster and hopefully more robust.
75
764.0 Fri Oct 5 12:56:00 CEST 2007
11 - incompatibly changed Coro::Storable::freeze. 77 - incompatibly changed Coro::Storable::freeze.
12 - added Coro::Debug, interactive coroutine debugging. 78 - major new feature: added Coro::Debug, for interactive coroutine
79 debugging, tracing and much more.
80 - major bug fix: unbelievable, but true: $_, $/ and many other
81 "saved" variables actually weren't being saved. This has been fixed,
82 of course, while increasing performance while losing all the save
83 flags.
84 - save flags are gone, and all the api functions dealing with them.
13 - added Coro::Semaphore::adjust. 85 - added Coro::Semaphore::adjust.
14 - added Coro::Util::fork_eval. 86 - added Coro::Util::fork_eval.
15 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}. 87 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
88 - added Coro::killall.
16 - reduce initial stack sizes to allow for "micro-coroutines". 89 - reduce initial stack sizes to allow for "micro-coroutines".
17 - better async_pool resource management, moved parts of async_pool 90 - better async_pool resource management, moved parts of async_pool
18 handling to XS. 91 handling to XS (major speed improvement).
92 - actually croak before modifying important data structures.
93 - refuse to transfer while compiling.
94 - possibly support eval EXPR better now.
95 - enable assembly per default on linux+bsd x86+amd64.
96 - all internal members were renamed _something for easier subclassing.
19 - many minor tweaks. 97 - many minor tweaks.

22 - implement handcoded assembly for x86/amd64 SVR ABI. 100 - implement handcoded assembly for x86/amd64 SVR ABI.
