8 - sprinkle "no warnings" freely over everything, also suppress
9 warnings for some other modules.
10
114.72 Sun May 25 05:14:36 CEST 2008
12 - tweak META.yaml a bit, unfortunately, there is no documented way
13 to have optional dependencies with CPAN. doh :(
14 - avoid running some tests on windows because they would fail due to
15 perl bug (broken fork, broken pipes...).
16 - work around perl on windows bugs where perl returns undocumented
17 error codes for sysread, syswrite etc. by taking advantage
18 of AnyEvent's workaround for that problem.
19 - use AnyEvent::Util::fh_nonblocking in Coro::Handle to work around
20 a common perl implementation bug on windows.
21 - use unix domain sockets in testsuite to work around
22 common perl implementation bugs on widows (they are emulated by
23 tcp sockets on windows. ugh.)
24
254.71 Sat May 24 20:01:27 CEST 2008
26 - fix a bug in Coro::AnyEvent ("Usage: Coro::AnyEvent::_schedule()").
27 - take advantage of async name resolution of AnyEvent::Util.
28 - work around brutal inet_aton override in Coro::LWP.
29 - take advantage of the readyhook in Coro::EV, for smoother
30 scheduling.
31
324.7 Sun May 11 00:32:19 CEST 2008
33 - completely reworked the Coro manpage.
34 - added Coro::AnyEvent, generic event loop integration.
35 - implement cancel, ready and kill commands in Coro::Debug.
36 - document find_coro in Coro::Debug.
37 - incompatible change: rename has_stack to has_cctx.
38 - Coro::AIO and Coro::BDB no longer force event model detection,
39 use AnyEvent::AIO and AnyEvent::BDB.
40
414.6 Sat Apr 26 10:05:14 CEST 2008
42 - INCOMPATIBLE CHANGE: sub/code attributes are no longer supported
43 by the Coro module. It was a mistake to have it in the first place.
44 - (experimental) support for activestate perl 5.10 (method "w").
45 - (experimental) support for strawberry perl (method "a").
46 - coro_sigelem_set did not return a value although it had to,
47 actual impact unknown.
48
494.51 Mon Apr 14 13:28:27 CEST 2008
50 - make it compile again on 5.8.
51
524.50 Thu Apr 10 09:43:17 CEST 2008
53 - I did it twice! (see 4.49).
54
554.49 Sun Apr 6 21:23:31 CEST 2008
56 - grr, instead of compiling the recent changes on 5.10 only they
57 were compiled on 5.8 only.
58
594.48 Sun Apr 6 20:36:46 CEST 2008
60 - allow coroutine switches during eval's under 5.10.x, as it seems
61 the parser is a per-interpreter option now, so this is safe
62 (this might fix the odd crashing bug).
63 - drop support for 5.9.x versions: they are dead, jim.
64
654.47 Sun Apr 6 00:37:52 CEST 2008
66 - force cctx allocation on API calls: we know we need to force one
67 and gcc actually manages to confuse our heuristic nowadays,
68 leading to crashes and worse.
69 - document force_cctx.
70
714.46 Fri Apr 4 22:05:43 CEST 2008
72 - upgrade libcoro, resulting in pthread-backend (which was only created
73 to fulfill the rules of the programming languages shootout).
74
754.45 Thu Mar 13 11:55:36 CET 2008
76 - fix a file leaking bug in eg/mhyttpd that would allow
77 downloading of any file (reported by oesi).
78 - fix deadlock bug in Coro::Channel (reported by Richard Hundt)
79 (also add testcase).
80 - support Broadcast option in Coro::Socket (patch by Richard Hundt,
81 apparently having loads of fun with that).
82 - implement $state->swap_defsv, ->swap_defav and document ->throw.
83
844.4 Wed Feb 13 16:44:29 CET 2008
85 - only assume .cfi pseudo isns exist on GNU/Linux.
86 - add get_timed method to Coro::Channels.
87 - fixed Coro::Debug manpage.
88 - perl 5.11 compatbility improvement based on patch by
89 Andreas König.
90
914.37 Sun Jan 20 11:25:23 CET 2008
92 - soften the check for an active parser for perl 5.10 (avoiding
93 "Coro::State::transfer called while parsing" in many cases).
94
954.36 Sun Jan 13 10:53:56 CET 2008
96 - reset diehook when terminating from an async_pool as to not
97 trigger any __DIE__ handlers.
98
994.35 Sun Jan 13 04:14:13 CET 2008
100 - "bt" debug command now displays any exceptions
101 from longmess and also skips the innermost
102 stackframes, giving more useufl output.
103 - allow backtraces in coroutines blocked in Coro::EV,
104 at a <1% speed hit.
105 - handle localising of $SIG{__WARN__} and __DIE__
106 properly (with a proper amount of dirty hacking).
107
1084.34 Sat Dec 22 17:49:53 CET 2007
109 - upgrade to EV version 2.0 API.
110
1114.33 Mon Dec 17 08:36:12 CET 2007
112 - make Coro::AIO etc. loadable in the absence of EV.
113
1144.32 Mon Dec 17 07:46:02 CET 2007
115 - majorly improved Coro::Handle's performance with Coro::EV.
116 - implemented the until now mythical Coro::BDB module.
117 - specialcase EV in Coro::AIO and Coro::BDB for extra speed.
118
1194.31 Wed Dec 5 12:32:39 CET 2007
120 - remove warn statement form Coro::Util.
121
1224.3 Tue Dec 4 20:33:14 CET 2007
123 - calls to the idle function could cause stack corruption
124 when the stack changed.
125 - do no longer rely on the presence of EV::DNS if EV is used
126 (because it is gone), but instead take avdantage of EV::ADNS
127 if available.
128 - add ($) prototypes to all functions in Coro::Storable.
129 - use a conventional (safer) idle callback in Coro::EV.
130 - do accept quickly in Coro::Debug to avoid endless loops.
131
1324.22 Fri Nov 30 16:04:04 CET 2007
133 - really use optimised versions for Event and EV in Coro::Util
134 and Coro::Handle.
135
1364.21 Sun Nov 25 10:48:59 CET 2007
137 - fix a spurious memory read.
138 - Coro::EV no longer keeps the eventloop "alive".
139
1404.2 Fri Nov 9 20:47:05 CET 2007
141 - enable/disable tracing from a new coroutine, not a pooled one.
142 - fix a memleak in Coro::Event.
143 - removed killall call from fork_eval.
144 - made sure store_fd is already loaded so that fork_eval
145 does not have to parse autoload in each subprocess.
146 - only use assembly method if -O switch is in $Config{optimize}.
147 - add (optional) Coro::EV module, so far the best event loop module
148 directly supported by Coro.
149 - if the event model is EV, use EV::DNS to resolve
150 stuff in Coro::Util.
151 - don't get confused by multiple event notifications in Coro::Handle.
152 - initial support for EV (libevent interface).
153 - require Event and EV using configure_requires, to force their existance.
154
1554.13 Wed Oct 24 07:26:45 CEST 2007
156 - add Coro::Storable::blocking_thaw.
157 - use a vastly more complicated technique to localise
158 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
159 - use a coroutine for the idle callback Coro::Event,
160 instead of running Event in the current coroutine context.
161 This also catches recursive invocations.
162 - actually report fork errors in gethostbyname and inet_aton.
163
1644.11 Thu Oct 11 02:40:24 CEST 2007
165 - port to threaded perls.
166
1674.1 Thu Oct 11 02:38:16 CEST 2007
168 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
169 be local to each coro (see Coro::State).
170 - incompatible change: for very deep reasons, cede and cede_notself
171 cannot return anything, so nothing will be returned.
172 - possibly bring back 5.10 compatibility (untested).
173 - work around stupid (and wrong) warning on 5.10 :(.
174 - overlay the saved state over the context stack. This saves
175 a few hundred bytes per coroutine on average and also
176 speeds up context switching a bit.
177 - further tune default stack sizes.
178 - (more) correctly calculate stack usage in coro_rss.
179 - Coro::Storable::blocking_* did not properly lock
180 resulting in races between coroutines.
181 - added Coro::Storable::guard.
182 - stopping to trace a coroutine could destroy the cctx of
183 an unrelated coroutine.
184 - explain the relationship between Perl and C coroutines in
185 more detail in Coro::State.
186 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
187 causing a fork per resolve. This also affected Coro::Socket.
188 - switch to a separate stack in $coro->call/eval to avoid
189 invalidating pointers.
190
1914.03 Sat Oct 6 21:24:00 CEST 2007
192 - added Coro::throw method.
193 - minor code cleanups.
194
1954.02 Sat Oct 6 02:36:47 CEST 2007
196 - fix a very minor per-coroutine memleak (a single codereference).
197 - fixed a bug where the currently in-use c context would be freed
198 prematurely (can happen only when programs change the stacksize
199 or use tracing).
200 - tracing can no longer keep a coro alive after it terminated.
201 - do static branch prediction in the common path for gcc. gives
202 about 2-5% speed improvement here.

84.01 Fri Oct 5 22:10:49 CEST 2007 2044.01 Fri Oct 5 22:10:49 CEST 2007
9 - instead of recreating *a* standard output handle we simply 205 - instead of recreating *a* standard output handle we simply
10 use STDOUT, which is faster and hopefully more robust. 206 use STDOUT, which is faster and hopefully more robust.
