84.02 8 - take advantage of async name resolution of AnyEvent::Util.
9 - work around brutal inet_aton override in Coro::LWP.
10
114.7 Sun May 11 00:32:19 CEST 2008
12 - completely reworked the Coro manpage.
13 - added Coro::AnyEvent, generic event loop integration.
14 - implement cancel, ready and kill commands in Coro::Debug.
15 - document find_coro in Coro::Debug.
16 - incompatible change: rename has_stack to has_cctx.
17 - Coro::AIO and Coro::BDB no longer force event model detection,
18 use AnyEvent::AIO and AnyEvent::BDB.
19
204.6 Sat Apr 26 10:05:14 CEST 2008
21 - INCOMPATIBLE CHANGE: sub/code attributes are no longer supported
22 by the Coro module. It was a mistake to have it in the first place.
23 - (experimental) support for activestate perl 5.10 (method "w").
24 - (experimental) support for strawberry perl (method "a").
25 - coro_sigelem_set did not return a value although it had to,
26 actual impact unknown.
27
284.51 Mon Apr 14 13:28:27 CEST 2008
29 - make it compile again on 5.8.
30
314.50 Thu Apr 10 09:43:17 CEST 2008
32 - I did it twice! (see 4.49).
33
344.49 Sun Apr 6 21:23:31 CEST 2008
35 - grr, instead of compiling the recent changes on 5.10 only they
36 were compiled on 5.8 only.
37
384.48 Sun Apr 6 20:36:46 CEST 2008
39 - allow coroutine switches during eval's under 5.10.x, as it seems
40 the parser is a per-interpreter option now, so this is safe
41 (this might fix the odd crashing bug).
42 - drop support for 5.9.x versions: they are dead, jim.
43
444.47 Sun Apr 6 00:37:52 CEST 2008
45 - force cctx allocation on API calls: we know we need to force one
46 and gcc actually manages to confuse our heuristic nowadays,
47 leading to crashes and worse.
48 - document force_cctx.
49
504.46 Fri Apr 4 22:05:43 CEST 2008
51 - upgrade libcoro, resulting in pthread-backend (which was only created
52 to fulfill the rules of the programming languages shootout).
53
544.45 Thu Mar 13 11:55:36 CET 2008
55 - fix a file leaking bug in eg/mhyttpd that would allow
56 downloading of any file (reported by oesi).
57 - fix deadlock bug in Coro::Channel (reported by Richard Hundt)
58 (also add testcase).
59 - support Broadcast option in Coro::Socket (patch by Richard Hundt,
60 apparently having loads of fun with that).
61 - implement $state->swap_defsv, ->swap_defav and document ->throw.
62
634.4 Wed Feb 13 16:44:29 CET 2008
64 - only assume .cfi pseudo isns exist on GNU/Linux.
65 - add get_timed method to Coro::Channels.
66 - fixed Coro::Debug manpage.
67 - perl 5.11 compatbility improvement based on patch by
68 Andreas König.
69
704.37 Sun Jan 20 11:25:23 CET 2008
71 - soften the check for an active parser for perl 5.10 (avoiding
72 "Coro::State::transfer called while parsing" in many cases).
73
744.36 Sun Jan 13 10:53:56 CET 2008
75 - reset diehook when terminating from an async_pool as to not
76 trigger any __DIE__ handlers.
77
784.35 Sun Jan 13 04:14:13 CET 2008
79 - "bt" debug command now displays any exceptions
80 from longmess and also skips the innermost
81 stackframes, giving more useufl output.
82 - allow backtraces in coroutines blocked in Coro::EV,
83 at a <1% speed hit.
84 - handle localising of $SIG{__WARN__} and __DIE__
85 properly (with a proper amount of dirty hacking).
86
874.34 Sat Dec 22 17:49:53 CET 2007
88 - upgrade to EV version 2.0 API.
89
904.33 Mon Dec 17 08:36:12 CET 2007
91 - make Coro::AIO etc. loadable in the absence of EV.
92
934.32 Mon Dec 17 07:46:02 CET 2007
94 - majorly improved Coro::Handle's performance with Coro::EV.
95 - implemented the until now mythical Coro::BDB module.
96 - specialcase EV in Coro::AIO and Coro::BDB for extra speed.
97
984.31 Wed Dec 5 12:32:39 CET 2007
99 - remove warn statement form Coro::Util.
100
1014.3 Tue Dec 4 20:33:14 CET 2007
102 - calls to the idle function could cause stack corruption
103 when the stack changed.
104 - do no longer rely on the presence of EV::DNS if EV is used
105 (because it is gone), but instead take avdantage of EV::ADNS
106 if available.
107 - add ($) prototypes to all functions in Coro::Storable.
108 - use a conventional (safer) idle callback in Coro::EV.
109 - do accept quickly in Coro::Debug to avoid endless loops.
110
1114.22 Fri Nov 30 16:04:04 CET 2007
112 - really use optimised versions for Event and EV in Coro::Util
113 and Coro::Handle.
114
1154.21 Sun Nov 25 10:48:59 CET 2007
116 - fix a spurious memory read.
117 - Coro::EV no longer keeps the eventloop "alive".
118
1194.2 Fri Nov 9 20:47:05 CET 2007
120 - enable/disable tracing from a new coroutine, not a pooled one.
121 - fix a memleak in Coro::Event.
122 - removed killall call from fork_eval.
123 - made sure store_fd is already loaded so that fork_eval
124 does not have to parse autoload in each subprocess.
125 - only use assembly method if -O switch is in $Config{optimize}.
126 - add (optional) Coro::EV module, so far the best event loop module
127 directly supported by Coro.
128 - if the event model is EV, use EV::DNS to resolve
129 stuff in Coro::Util.
130 - don't get confused by multiple event notifications in Coro::Handle.
131 - initial support for EV (libevent interface).
132 - require Event and EV using configure_requires, to force their existance.
133
1344.13 Wed Oct 24 07:26:45 CEST 2007
135 - add Coro::Storable::blocking_thaw.
136 - use a vastly more complicated technique to localise
137 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
138 - use a coroutine for the idle callback Coro::Event,
139 instead of running Event in the current coroutine context.
140 This also catches recursive invocations.
141 - actually report fork errors in gethostbyname and inet_aton.
142
1434.11 Thu Oct 11 02:40:24 CEST 2007
144 - port to threaded perls.
145
1464.1 Thu Oct 11 02:38:16 CEST 2007
147 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
148 be local to each coro (see Coro::State).
149 - incompatible change: for very deep reasons, cede and cede_notself
150 cannot return anything, so nothing will be returned.
151 - possibly bring back 5.10 compatibility (untested).
152 - work around stupid (and wrong) warning on 5.10 :(.
153 - overlay the saved state over the context stack. This saves
154 a few hundred bytes per coroutine on average and also
155 speeds up context switching a bit.
156 - further tune default stack sizes.
157 - (more) correctly calculate stack usage in coro_rss.
158 - Coro::Storable::blocking_* did not properly lock
159 resulting in races between coroutines.
160 - added Coro::Storable::guard.
161 - stopping to trace a coroutine could destroy the cctx of
162 an unrelated coroutine.
163 - explain the relationship between Perl and C coroutines in
164 more detail in Coro::State.
165 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
166 causing a fork per resolve. This also affected Coro::Socket.
167 - switch to a separate stack in $coro->call/eval to avoid
168 invalidating pointers.
169
1704.03 Sat Oct 6 21:24:00 CEST 2007
171 - added Coro::throw method.
172 - minor code cleanups.
173
1744.02 Sat Oct 6 02:36:47 CEST 2007
9 - fix a very minor per-coroutine memleak (a single codereference). 175 - fix a very minor per-coroutine memleak (a single codereference).
10 - fixed a bug where the currently in-use c context would be freed 176 - fixed a bug where the currently in-use c context would be freed
11 prematurely (can happen only when programs change the stacksize 177 prematurely (can happen only when programs change the stacksize
12 or use tracing). 178 or use tracing).
13 - tracing can no longer keep a coro alive after it terminated. 179 - tracing can no longer keep a coro alive after it terminated.
180 - do static branch prediction in the common path for gcc. gives
181 about 2-5% speed improvement here.

154.01 Fri Oct 5 22:10:49 CEST 2007 1834.01 Fri Oct 5 22:10:49 CEST 2007
16 - instead of recreating *a* standard output handle we simply 184 - instead of recreating *a* standard output handle we simply
17 use STDOUT, which is faster and hopefully more robust. 185 use STDOUT, which is faster and hopefully more robust.
