84.0 84.50 Thu Apr 10 09:43:17 CEST 2008
9 - I did it twice! (see 4.49).
10
114.49 Sun Apr 6 21:23:31 CEST 2008
12 - grr, instead of compiling the recent changes on 5.10 only they
13 were compiled on 5.8 only.
14
154.48 Sun Apr 6 20:36:46 CEST 2008
16 - allow coroutine switches during eval's under 5.10.x, as it seems
17 the parser is a per-interpreter option now, so this is safe
18 (this might fix the odd crashing bug).
19 - drop support for 5.9.x versions: they are dead, jim.
20
214.47 Sun Apr 6 00:37:52 CEST 2008
22 - force cctx allocation on API calls: we know we need to force one
23 and gcc actually manages to confuse our heuristic nowadays,
24 leading to crashes and worse.
25 - document force_cctx.
26
274.46 Fri Apr 4 22:05:43 CEST 2008
28 - upgrade libcoro, resulting in pthread-backend (which was only created
29 to fulfill the rules of the programming languages shootout).
30
314.45 Thu Mar 13 11:55:36 CET 2008
32 - fix a file leaking bug in eg/mhyttpd that would allow
33 downloading of any file (reported by oesi).
34 - fix deadlock bug in Coro::Channel (reported by Richard Hundt)
35 (also add testcase).
36 - support Broadcast option in Coro::Socket (patch by Richard Hundt,
37 apparently having loads of fun with that).
38 - implement $state->swap_defsv, ->swap_defav and document ->throw.
39
404.4 Wed Feb 13 16:44:29 CET 2008
41 - only assume .cfi pseudo isns exist on GNU/Linux.
42 - add get_timed method to Coro::Channels.
43 - fixed Coro::Debug manpage.
44 - perl 5.11 compatbility improvement based on patch by
45 Andreas König.
46
474.37 Sun Jan 20 11:25:23 CET 2008
48 - soften the check for an active parser for perl 5.10 (avoiding
49 "Coro::State::transfer called while parsing" in many cases).
50
514.36 Sun Jan 13 10:53:56 CET 2008
52 - reset diehook when terminating from an async_pool as to not
53 trigger any __DIE__ handlers.
54
554.35 Sun Jan 13 04:14:13 CET 2008
56 - "bt" debug command now displays any exceptions
57 from longmess and also skips the innermost
58 stackframes, giving more useufl output.
59 - allow backtraces in coroutines blocked in Coro::EV,
60 at a <1% speed hit.
61 - handle localising of $SIG{__WARN__} and __DIE__
62 properly (with a proper amount of dirty hacking).
63
644.34 Sat Dec 22 17:49:53 CET 2007
65 - upgrade to EV version 2.0 API.
66
674.33 Mon Dec 17 08:36:12 CET 2007
68 - make Coro::AIO etc. loadable in the absence of EV.
69
704.32 Mon Dec 17 07:46:02 CET 2007
71 - majorly improved Coro::Handle's performance with Coro::EV.
72 - implemented the until now mythical Coro::BDB module.
73 - specialcase EV in Coro::AIO and Coro::BDB for extra speed.
74
754.31 Wed Dec 5 12:32:39 CET 2007
76 - remove warn statement form Coro::Util.
77
784.3 Tue Dec 4 20:33:14 CET 2007
79 - calls to the idle function could cause stack corruption
80 when the stack changed.
81 - do no longer rely on the presence of EV::DNS if EV is used
82 (because it is gone), but instead take avdantage of EV::ADNS
83 if available.
84 - add ($) prototypes to all functions in Coro::Storable.
85 - use a conventional (safer) idle callback in Coro::EV.
86 - do accept quickly in Coro::Debug to avoid endless loops.
87
884.22 Fri Nov 30 16:04:04 CET 2007
89 - really use optimised versions for Event and EV in Coro::Util
90 and Coro::Handle.
91
924.21 Sun Nov 25 10:48:59 CET 2007
93 - fix a spurious memory read.
94 - Coro::EV no longer keeps the eventloop "alive".
95
964.2 Fri Nov 9 20:47:05 CET 2007
97 - enable/disable tracing from a new coroutine, not a pooled one.
98 - fix a memleak in Coro::Event.
99 - removed killall call from fork_eval.
100 - made sure store_fd is already loaded so that fork_eval
101 does not have to parse autoload in each subprocess.
102 - only use assembly method if -O switch is in $Config{optimize}.
103 - add (optional) Coro::EV module, so far the best event loop module
104 directly supported by Coro.
105 - if the event model is EV, use EV::DNS to resolve
106 stuff in Coro::Util.
107 - don't get confused by multiple event notifications in Coro::Handle.
108 - initial support for EV (libevent interface).
109 - require Event and EV using configure_requires, to force their existance.
110
1114.13 Wed Oct 24 07:26:45 CEST 2007
112 - add Coro::Storable::blocking_thaw.
113 - use a vastly more complicated technique to localise
114 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
115 - use a coroutine for the idle callback Coro::Event,
116 instead of running Event in the current coroutine context.
117 This also catches recursive invocations.
118 - actually report fork errors in gethostbyname and inet_aton.
119
1204.11 Thu Oct 11 02:40:24 CEST 2007
121 - port to threaded perls.
122
1234.1 Thu Oct 11 02:38:16 CEST 2007
124 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
125 be local to each coro (see Coro::State).
126 - incompatible change: for very deep reasons, cede and cede_notself
127 cannot return anything, so nothing will be returned.
128 - possibly bring back 5.10 compatibility (untested).
129 - work around stupid (and wrong) warning on 5.10 :(.
130 - overlay the saved state over the context stack. This saves
131 a few hundred bytes per coroutine on average and also
132 speeds up context switching a bit.
133 - further tune default stack sizes.
134 - (more) correctly calculate stack usage in coro_rss.
135 - Coro::Storable::blocking_* did not properly lock
136 resulting in races between coroutines.
137 - added Coro::Storable::guard.
138 - stopping to trace a coroutine could destroy the cctx of
139 an unrelated coroutine.
140 - explain the relationship between Perl and C coroutines in
141 more detail in Coro::State.
142 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
143 causing a fork per resolve. This also affected Coro::Socket.
144 - switch to a separate stack in $coro->call/eval to avoid
145 invalidating pointers.
146
1474.03 Sat Oct 6 21:24:00 CEST 2007
148 - added Coro::throw method.
149 - minor code cleanups.
150
1514.02 Sat Oct 6 02:36:47 CEST 2007
152 - fix a very minor per-coroutine memleak (a single codereference).
153 - fixed a bug where the currently in-use c context would be freed
154 prematurely (can happen only when programs change the stacksize
155 or use tracing).
156 - tracing can no longer keep a coro alive after it terminated.
157 - do static branch prediction in the common path for gcc. gives
158 about 2-5% speed improvement here.
159
1604.01 Fri Oct 5 22:10:49 CEST 2007
161 - instead of recreating *a* standard output handle we simply
162 use STDOUT, which is faster and hopefully more robust.
163
1644.0 Fri Oct 5 12:56:00 CEST 2007
