84.0 8 - fix a file leaking bug in eg/mhyttpd that would allow
9 downloading of any file (reported by oesi).
10 - fix deadlock bug in Coro::Channel (reported by Richard Hundt)
11 (also add testcase).
12 - support Broadcast option in Coro::Socket (patch by Richard Hundt,
13 apparently having loads of fun with that).
14 - implement $state->swap_defsv, ->swap_defav and document ->throw.
15
164.4 Wed Feb 13 16:44:29 CET 2008
17 - only assume .cfi pseudo isns exist on GNU/Linux.
18 - add get_timed method to Coro::Channels.
19 - fixed Coro::Debug manpage.
20 - perl 5.11 compatbility improvement based on patch by
21 Andreas König.
22
234.37 Sun Jan 20 11:25:23 CET 2008
24 - soften the check for an active parser for perl 5.10 (avoiding
25 "Coro::State::transfer called while parsing" in many cases).
26
274.36 Sun Jan 13 10:53:56 CET 2008
28 - reset diehook when terminating from an async_pool as to not
29 trigger any __DIE__ handlers.
30
314.35 Sun Jan 13 04:14:13 CET 2008
32 - "bt" debug command now displays any exceptions
33 from longmess and also skips the innermost
34 stackframes, giving more useufl output.
35 - allow backtraces in coroutines blocked in Coro::EV,
36 at a <1% speed hit.
37 - handle localising of $SIG{__WARN__} and __DIE__
38 properly (with a proper amount of dirty hacking).
39
404.34 Sat Dec 22 17:49:53 CET 2007
41 - upgrade to EV version 2.0 API.
42
434.33 Mon Dec 17 08:36:12 CET 2007
44 - make Coro::AIO etc. loadable in the absence of EV.
45
464.32 Mon Dec 17 07:46:02 CET 2007
47 - majorly improved Coro::Handle's performance with Coro::EV.
48 - implemented the until now mythical Coro::BDB module.
49 - specialcase EV in Coro::AIO and Coro::BDB for extra speed.
50
514.31 Wed Dec 5 12:32:39 CET 2007
52 - remove warn statement form Coro::Util.
53
544.3 Tue Dec 4 20:33:14 CET 2007
55 - calls to the idle function could cause stack corruption
56 when the stack changed.
57 - do no longer rely on the presence of EV::DNS if EV is used
58 (because it is gone), but instead take avdantage of EV::ADNS
59 if available.
60 - add ($) prototypes to all functions in Coro::Storable.
61 - use a conventional (safer) idle callback in Coro::EV.
62 - do accept quickly in Coro::Debug to avoid endless loops.
63
644.22 Fri Nov 30 16:04:04 CET 2007
65 - really use optimised versions for Event and EV in Coro::Util
66 and Coro::Handle.
67
684.21 Sun Nov 25 10:48:59 CET 2007
69 - fix a spurious memory read.
70 - Coro::EV no longer keeps the eventloop "alive".
71
724.2 Fri Nov 9 20:47:05 CET 2007
73 - enable/disable tracing from a new coroutine, not a pooled one.
74 - fix a memleak in Coro::Event.
75 - removed killall call from fork_eval.
76 - made sure store_fd is already loaded so that fork_eval
77 does not have to parse autoload in each subprocess.
78 - only use assembly method if -O switch is in $Config{optimize}.
79 - add (optional) Coro::EV module, so far the best event loop module
80 directly supported by Coro.
81 - if the event model is EV, use EV::DNS to resolve
82 stuff in Coro::Util.
83 - don't get confused by multiple event notifications in Coro::Handle.
84 - initial support for EV (libevent interface).
85 - require Event and EV using configure_requires, to force their existance.
86
874.13 Wed Oct 24 07:26:45 CEST 2007
88 - add Coro::Storable::blocking_thaw.
89 - use a vastly more complicated technique to localise
90 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
91 - use a coroutine for the idle callback Coro::Event,
92 instead of running Event in the current coroutine context.
93 This also catches recursive invocations.
94 - actually report fork errors in gethostbyname and inet_aton.
95
964.11 Thu Oct 11 02:40:24 CEST 2007
97 - port to threaded perls.
98
994.1 Thu Oct 11 02:38:16 CEST 2007
100 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
101 be local to each coro (see Coro::State).
102 - incompatible change: for very deep reasons, cede and cede_notself
103 cannot return anything, so nothing will be returned.
104 - possibly bring back 5.10 compatibility (untested).
105 - work around stupid (and wrong) warning on 5.10 :(.
106 - overlay the saved state over the context stack. This saves
107 a few hundred bytes per coroutine on average and also
108 speeds up context switching a bit.
109 - further tune default stack sizes.
110 - (more) correctly calculate stack usage in coro_rss.
111 - Coro::Storable::blocking_* did not properly lock
112 resulting in races between coroutines.
113 - added Coro::Storable::guard.
114 - stopping to trace a coroutine could destroy the cctx of
115 an unrelated coroutine.
116 - explain the relationship between Perl and C coroutines in
117 more detail in Coro::State.
118 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
119 causing a fork per resolve. This also affected Coro::Socket.
120 - switch to a separate stack in $coro->call/eval to avoid
121 invalidating pointers.
122
1234.03 Sat Oct 6 21:24:00 CEST 2007
124 - added Coro::throw method.
125 - minor code cleanups.
126
1274.02 Sat Oct 6 02:36:47 CEST 2007
128 - fix a very minor per-coroutine memleak (a single codereference).
129 - fixed a bug where the currently in-use c context would be freed
130 prematurely (can happen only when programs change the stacksize
131 or use tracing).
132 - tracing can no longer keep a coro alive after it terminated.
133 - do static branch prediction in the common path for gcc. gives
134 about 2-5% speed improvement here.
135
1364.01 Fri Oct 5 22:10:49 CEST 2007
137 - instead of recreating *a* standard output handle we simply
138 use STDOUT, which is faster and hopefully more robust.
139
1404.0 Fri Oct 5 12:56:00 CEST 2007
