84.4 Wed Feb 13 16:44:29 CET 2008
9 - only assume .cfi pseudo isns exist on GNU/Linux.
10 - add get_timed method to Coro::Channels.
11 - fixed Coro::Debug manpage.
12 - perl 5.11 compatbility improvement based on patch by
13 Andreas König.
14
154.37 Sun Jan 20 11:25:23 CET 2008
16 - soften the check for an active parser for perl 5.10 (avoiding
17 "Coro::State::transfer called while parsing" in many cases).
18
194.36 Sun Jan 13 10:53:56 CET 2008
20 - reset diehook when terminating from an async_pool as to not
21 trigger any __DIE__ handlers.
22
234.35 Sun Jan 13 04:14:13 CET 2008
24 - "bt" debug command now displays any exceptions
25 from longmess and also skips the innermost
26 stackframes, giving more useufl output.
27 - allow backtraces in coroutines blocked in Coro::EV,
28 at a <1% speed hit.
29 - handle localising of $SIG{__WARN__} and __DIE__
30 properly (with a proper amount of dirty hacking).
31
324.34 Sat Dec 22 17:49:53 CET 2007
33 - upgrade to EV version 2.0 API.
34
354.33 Mon Dec 17 08:36:12 CET 2007
36 - make Coro::AIO etc. loadable in the absence of EV.
37
384.32 Mon Dec 17 07:46:02 CET 2007
39 - majorly improved Coro::Handle's performance with Coro::EV.
40 - implemented the until now mythical Coro::BDB module.
41 - specialcase EV in Coro::AIO and Coro::BDB for extra speed.
42
434.31 Wed Dec 5 12:32:39 CET 2007
44 - remove warn statement form Coro::Util.
45
464.3 Tue Dec 4 20:33:14 CET 2007
47 - calls to the idle function could cause stack corruption
48 when the stack changed.
49 - do no longer rely on the presence of EV::DNS if EV is used
50 (because it is gone), but instead take avdantage of EV::ADNS
51 if available.
52 - add ($) prototypes to all functions in Coro::Storable.
53 - use a conventional (safer) idle callback in Coro::EV.
54 - do accept quickly in Coro::Debug to avoid endless loops.
55
564.22 Fri Nov 30 16:04:04 CET 2007
57 - really use optimised versions for Event and EV in Coro::Util
58 and Coro::Handle.
59
604.21 Sun Nov 25 10:48:59 CET 2007
61 - fix a spurious memory read.
62 - Coro::EV no longer keeps the eventloop "alive".
63
644.2 Fri Nov 9 20:47:05 CET 2007
65 - enable/disable tracing from a new coroutine, not a pooled one.
66 - fix a memleak in Coro::Event.
67 - removed killall call from fork_eval.
68 - made sure store_fd is already loaded so that fork_eval
69 does not have to parse autoload in each subprocess.
70 - only use assembly method if -O switch is in $Config{optimize}.
71 - add (optional) Coro::EV module, so far the best event loop module
72 directly supported by Coro.
73 - if the event model is EV, use EV::DNS to resolve
74 stuff in Coro::Util.
75 - don't get confused by multiple event notifications in Coro::Handle.
76 - initial support for EV (libevent interface).
77 - require Event and EV using configure_requires, to force their existance.
78
794.13 Wed Oct 24 07:26:45 CEST 2007
80 - add Coro::Storable::blocking_thaw.
81 - use a vastly more complicated technique to localise
82 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
83 - use a coroutine for the idle callback Coro::Event,
84 instead of running Event in the current coroutine context.
85 This also catches recursive invocations.
86 - actually report fork errors in gethostbyname and inet_aton.
87
884.11 Thu Oct 11 02:40:24 CEST 2007
89 - port to threaded perls.
90
914.1 Thu Oct 11 02:38:16 CEST 2007
9 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now 92 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
10 be local to each coro (see Coro::State). 93 be local to each coro (see Coro::State).
94 - incompatible change: for very deep reasons, cede and cede_notself
95 cannot return anything, so nothing will be returned.
11 - possibly bring back 5.10 compatibility (untested). 96 - possibly bring back 5.10 compatibility (untested).
12 - work around stupid (and wrong) warning on 5.10 :(. 97 - work around stupid (and wrong) warning on 5.10 :(.
13 - overlay the saved state over the context stack. This saves 98 - overlay the saved state over the context stack. This saves
14 a few hundred bytes per coroutine on average and also 99 a few hundred bytes per coroutine on average and also
15 speeds up context switching a bit. 100 speeds up context switching a bit.
101 - further tune default stack sizes.
16 - (more) correctly calculate stack usage in coro_rss. 102 - (more) correctly calculate stack usage in coro_rss.
103 - Coro::Storable::blocking_* did not properly lock
104 resulting in races between coroutines.
105 - added Coro::Storable::guard.
106 - stopping to trace a coroutine could destroy the cctx of
107 an unrelated coroutine.
108 - explain the relationship between Perl and C coroutines in
109 more detail in Coro::State.
110 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
111 causing a fork per resolve. This also affected Coro::Socket.
112 - switch to a separate stack in $coro->call/eval to avoid
113 invalidating pointers.

184.03 Sat Oct 6 21:24:00 CEST 2007 1154.03 Sat Oct 6 21:24:00 CEST 2007
19 - added Coro::throw method. 116 - added Coro::throw method.
20 - minor code cleanups. 117 - minor code cleanups.
