84.1 8 - fix a bug in Coro::AnyEvent ("Usage: Coro::AnyEvent::_schedule()").
9 - take advantage of async name resolution of AnyEvent::Util.
10 - work around brutal inet_aton override in Coro::LWP.
11 - take advantage of the readyhook in Coro::EV, for smoother
12 scheduling.
13
144.7 Sun May 11 00:32:19 CEST 2008
15 - completely reworked the Coro manpage.
16 - added Coro::AnyEvent, generic event loop integration.
17 - implement cancel, ready and kill commands in Coro::Debug.
18 - document find_coro in Coro::Debug.
19 - incompatible change: rename has_stack to has_cctx.
20 - Coro::AIO and Coro::BDB no longer force event model detection,
21 use AnyEvent::AIO and AnyEvent::BDB.
22
234.6 Sat Apr 26 10:05:14 CEST 2008
24 - INCOMPATIBLE CHANGE: sub/code attributes are no longer supported
25 by the Coro module. It was a mistake to have it in the first place.
26 - (experimental) support for activestate perl 5.10 (method "w").
27 - (experimental) support for strawberry perl (method "a").
28 - coro_sigelem_set did not return a value although it had to,
29 actual impact unknown.
30
314.51 Mon Apr 14 13:28:27 CEST 2008
32 - make it compile again on 5.8.
33
344.50 Thu Apr 10 09:43:17 CEST 2008
35 - I did it twice! (see 4.49).
36
374.49 Sun Apr 6 21:23:31 CEST 2008
38 - grr, instead of compiling the recent changes on 5.10 only they
39 were compiled on 5.8 only.
40
414.48 Sun Apr 6 20:36:46 CEST 2008
42 - allow coroutine switches during eval's under 5.10.x, as it seems
43 the parser is a per-interpreter option now, so this is safe
44 (this might fix the odd crashing bug).
45 - drop support for 5.9.x versions: they are dead, jim.
46
474.47 Sun Apr 6 00:37:52 CEST 2008
48 - force cctx allocation on API calls: we know we need to force one
49 and gcc actually manages to confuse our heuristic nowadays,
50 leading to crashes and worse.
51 - document force_cctx.
52
534.46 Fri Apr 4 22:05:43 CEST 2008
54 - upgrade libcoro, resulting in pthread-backend (which was only created
55 to fulfill the rules of the programming languages shootout).
56
574.45 Thu Mar 13 11:55:36 CET 2008
58 - fix a file leaking bug in eg/mhyttpd that would allow
59 downloading of any file (reported by oesi).
60 - fix deadlock bug in Coro::Channel (reported by Richard Hundt)
61 (also add testcase).
62 - support Broadcast option in Coro::Socket (patch by Richard Hundt,
63 apparently having loads of fun with that).
64 - implement $state->swap_defsv, ->swap_defav and document ->throw.
65
664.4 Wed Feb 13 16:44:29 CET 2008
67 - only assume .cfi pseudo isns exist on GNU/Linux.
68 - add get_timed method to Coro::Channels.
69 - fixed Coro::Debug manpage.
70 - perl 5.11 compatbility improvement based on patch by
71 Andreas König.
72
734.37 Sun Jan 20 11:25:23 CET 2008
74 - soften the check for an active parser for perl 5.10 (avoiding
75 "Coro::State::transfer called while parsing" in many cases).
76
774.36 Sun Jan 13 10:53:56 CET 2008
78 - reset diehook when terminating from an async_pool as to not
79 trigger any __DIE__ handlers.
80
814.35 Sun Jan 13 04:14:13 CET 2008
82 - "bt" debug command now displays any exceptions
83 from longmess and also skips the innermost
84 stackframes, giving more useufl output.
85 - allow backtraces in coroutines blocked in Coro::EV,
86 at a <1% speed hit.
87 - handle localising of $SIG{__WARN__} and __DIE__
88 properly (with a proper amount of dirty hacking).
89
904.34 Sat Dec 22 17:49:53 CET 2007
91 - upgrade to EV version 2.0 API.
92
934.33 Mon Dec 17 08:36:12 CET 2007
94 - make Coro::AIO etc. loadable in the absence of EV.
95
964.32 Mon Dec 17 07:46:02 CET 2007
97 - majorly improved Coro::Handle's performance with Coro::EV.
98 - implemented the until now mythical Coro::BDB module.
99 - specialcase EV in Coro::AIO and Coro::BDB for extra speed.
100
1014.31 Wed Dec 5 12:32:39 CET 2007
102 - remove warn statement form Coro::Util.
103
1044.3 Tue Dec 4 20:33:14 CET 2007
105 - calls to the idle function could cause stack corruption
106 when the stack changed.
107 - do no longer rely on the presence of EV::DNS if EV is used
108 (because it is gone), but instead take avdantage of EV::ADNS
109 if available.
110 - add ($) prototypes to all functions in Coro::Storable.
111 - use a conventional (safer) idle callback in Coro::EV.
112 - do accept quickly in Coro::Debug to avoid endless loops.
113
1144.22 Fri Nov 30 16:04:04 CET 2007
115 - really use optimised versions for Event and EV in Coro::Util
116 and Coro::Handle.
117
1184.21 Sun Nov 25 10:48:59 CET 2007
119 - fix a spurious memory read.
120 - Coro::EV no longer keeps the eventloop "alive".
121
1224.2 Fri Nov 9 20:47:05 CET 2007
123 - enable/disable tracing from a new coroutine, not a pooled one.
124 - fix a memleak in Coro::Event.
125 - removed killall call from fork_eval.
126 - made sure store_fd is already loaded so that fork_eval
127 does not have to parse autoload in each subprocess.
128 - only use assembly method if -O switch is in $Config{optimize}.
129 - add (optional) Coro::EV module, so far the best event loop module
130 directly supported by Coro.
131 - if the event model is EV, use EV::DNS to resolve
132 stuff in Coro::Util.
133 - don't get confused by multiple event notifications in Coro::Handle.
134 - initial support for EV (libevent interface).
135 - require Event and EV using configure_requires, to force their existance.
136
1374.13 Wed Oct 24 07:26:45 CEST 2007
138 - add Coro::Storable::blocking_thaw.
139 - use a vastly more complicated technique to localise
140 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
141 - use a coroutine for the idle callback Coro::Event,
142 instead of running Event in the current coroutine context.
143 This also catches recursive invocations.
144 - actually report fork errors in gethostbyname and inet_aton.
145
1464.11 Thu Oct 11 02:40:24 CEST 2007
147 - port to threaded perls.
148
1494.1 Thu Oct 11 02:38:16 CEST 2007
9 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now 150 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
10 be local to each coro (see Coro::State). 151 be local to each coro (see Coro::State).
152 - incompatible change: for very deep reasons, cede and cede_notself
153 cannot return anything, so nothing will be returned.
11 - possibly bring back 5.10 compatibility (untested). 154 - possibly bring back 5.10 compatibility (untested).
12 - work around stupid (and wrong) warning on 5.10 :(. 155 - work around stupid (and wrong) warning on 5.10 :(.
13 - overlay the saved state over the context stack. This saves 156 - overlay the saved state over the context stack. This saves
14 a few hundred bytes per coroutine on average and also 157 a few hundred bytes per coroutine on average and also
15 speeds up context switching a bit. 158 speeds up context switching a bit.

18 - Coro::Storable::blocking_* did not properly lock 161 - Coro::Storable::blocking_* did not properly lock
19 resulting in races between coroutines. 162 resulting in races between coroutines.
20 - added Coro::Storable::guard. 163 - added Coro::Storable::guard.
21 - stopping to trace a coroutine could destroy the cctx of 164 - stopping to trace a coroutine could destroy the cctx of
22 an unrelated coroutine. 165 an unrelated coroutine.
166 - explain the relationship between Perl and C coroutines in
167 more detail in Coro::State.
168 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
169 causing a fork per resolve. This also affected Coro::Socket.
170 - switch to a separate stack in $coro->call/eval to avoid
171 invalidating pointers.

244.03 Sat Oct 6 21:24:00 CEST 2007 1734.03 Sat Oct 6 21:24:00 CEST 2007
