84.4
9 - only assume .cfi pseudo isns exist on GNU/Linux.
10 - add get_timed method to Coro::Channels.
11
124.37 Sun Jan 20 11:25:23 CET 2008
13 - soften the check for an active parser for perl 5.10 (avoiding
14 "Coro::State::transfer called while parsing" in many cases).
15
164.36 Sun Jan 13 10:53:56 CET 2008
17 - reset diehook when terminating from an async_pool as to not
18 trigger any __DIE__ handlers.
19
204.35 Sun Jan 13 04:14:13 CET 2008
21 - "bt" debug command now displays any exceptions
22 from longmess and also skips the innermost
23 stackframes, giving more useufl output.
24 - allow backtraces in coroutines blocked in Coro::EV,
25 at a <1% speed hit.
26 - handle localising of $SIG{__WARN__} and __DIE__
27 properly (with a proper amount of dirty hacking).
28
294.34 Sat Dec 22 17:49:53 CET 2007
30 - upgrade to EV version 2.0 API.
31
324.33 Mon Dec 17 08:36:12 CET 2007
33 - make Coro::AIO etc. loadable in the absence of EV.
34
354.32 Mon Dec 17 07:46:02 CET 2007
36 - majorly improved Coro::Handle's performance with Coro::EV.
37 - implemented the until now mythical Coro::BDB module.
38 - specialcase EV in Coro::AIO and Coro::BDB for extra speed.
39
404.31 Wed Dec 5 12:32:39 CET 2007
41 - remove warn statement form Coro::Util.
42
434.3 Tue Dec 4 20:33:14 CET 2007
44 - calls to the idle function could cause stack corruption
45 when the stack changed.
46 - do no longer rely on the presence of EV::DNS if EV is used
47 (because it is gone), but instead take avdantage of EV::ADNS
48 if available.
49 - add ($) prototypes to all functions in Coro::Storable.
50 - use a conventional (safer) idle callback in Coro::EV.
51 - do accept quickly in Coro::Debug to avoid endless loops.
52
534.22 Fri Nov 30 16:04:04 CET 2007
54 - really use optimised versions for Event and EV in Coro::Util
55 and Coro::Handle.
56
574.21 Sun Nov 25 10:48:59 CET 2007
58 - fix a spurious memory read.
59 - Coro::EV no longer keeps the eventloop "alive".
60
614.2 Fri Nov 9 20:47:05 CET 2007
62 - enable/disable tracing from a new coroutine, not a pooled one.
63 - fix a memleak in Coro::Event.
64 - removed killall call from fork_eval.
65 - made sure store_fd is already loaded so that fork_eval
66 does not have to parse autoload in each subprocess.
67 - only use assembly method if -O switch is in $Config{optimize}.
68 - add (optional) Coro::EV module, so far the best event loop module
69 directly supported by Coro.
70 - if the event model is EV, use EV::DNS to resolve
71 stuff in Coro::Util.
72 - don't get confused by multiple event notifications in Coro::Handle.
73 - initial support for EV (libevent interface).
74 - require Event and EV using configure_requires, to force their existance.
75
764.13 Wed Oct 24 07:26:45 CEST 2007
77 - add Coro::Storable::blocking_thaw.
78 - use a vastly more complicated technique to localise
79 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
80 - use a coroutine for the idle callback Coro::Event,
81 instead of running Event in the current coroutine context.
82 This also catches recursive invocations.
83 - actually report fork errors in gethostbyname and inet_aton.
84
854.11 Thu Oct 11 02:40:24 CEST 2007
86 - port to threaded perls.
87
884.1 Thu Oct 11 02:38:16 CEST 2007
9 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now 89 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
10 be local to each coro (see Coro::State). 90 be local to each coro (see Coro::State).
91 - incompatible change: for very deep reasons, cede and cede_notself
92 cannot return anything, so nothing will be returned.
11 - possibly bring back 5.10 compatibility (untested). 93 - possibly bring back 5.10 compatibility (untested).
12 - work around stupid (and wrong) warning on 5.10 :(. 94 - work around stupid (and wrong) warning on 5.10 :(.
13 - overlay the saved state over the context stack. This saves 95 - overlay the saved state over the context stack. This saves
14 a few hundred bytes per coroutine on average and also 96 a few hundred bytes per coroutine on average and also
15 speeds up context switching a bit. 97 speeds up context switching a bit.
98 - further tune default stack sizes.
16 - (more) correctly calculate stack usage in coro_rss. 99 - (more) correctly calculate stack usage in coro_rss.
100 - Coro::Storable::blocking_* did not properly lock
101 resulting in races between coroutines.
102 - added Coro::Storable::guard.
103 - stopping to trace a coroutine could destroy the cctx of
104 an unrelated coroutine.
105 - explain the relationship between Perl and C coroutines in
106 more detail in Coro::State.
107 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
108 causing a fork per resolve. This also affected Coro::Socket.
109 - switch to a separate stack in $coro->call/eval to avoid
110 invalidating pointers.

19 - added Coro::throw method. 113 - added Coro::throw method.
20 - minor code cleanups. 114 - minor code cleanups.
