84.6 Sat Apr 26 10:05:14 CEST 2008
9 - INCOMPATIBLE CHANGE: sub/code attributes are no longer supported
10 by the Coro module. It was a mistake to have it in the first place.
11 - (experimental) support for activestate perl 5.10 (method "w").
12 - (experimental) support for strawberry perl (method "a").
13 - coro_sigelem_set did not return a value although it had to,
14 actual impact unknown.
15
164.51 Mon Apr 14 13:28:27 CEST 2008
17 - make it compile again on 5.8.
18
194.50 Thu Apr 10 09:43:17 CEST 2008
20 - I did it twice! (see 4.49).
21
224.49 Sun Apr 6 21:23:31 CEST 2008
23 - grr, instead of compiling the recent changes on 5.10 only they
24 were compiled on 5.8 only.
25
264.48 Sun Apr 6 20:36:46 CEST 2008
27 - allow coroutine switches during eval's under 5.10.x, as it seems
28 the parser is a per-interpreter option now, so this is safe
29 (this might fix the odd crashing bug).
30 - drop support for 5.9.x versions: they are dead, jim.
31
324.47 Sun Apr 6 00:37:52 CEST 2008
33 - force cctx allocation on API calls: we know we need to force one
34 and gcc actually manages to confuse our heuristic nowadays,
35 leading to crashes and worse.
36 - document force_cctx.
37
384.46 Fri Apr 4 22:05:43 CEST 2008
39 - upgrade libcoro, resulting in pthread-backend (which was only created
40 to fulfill the rules of the programming languages shootout).
41
424.45 Thu Mar 13 11:55:36 CET 2008
43 - fix a file leaking bug in eg/mhyttpd that would allow
44 downloading of any file (reported by oesi).
45 - fix deadlock bug in Coro::Channel (reported by Richard Hundt)
46 (also add testcase).
47 - support Broadcast option in Coro::Socket (patch by Richard Hundt,
48 apparently having loads of fun with that).
49 - implement $state->swap_defsv, ->swap_defav and document ->throw.
50
514.4 Wed Feb 13 16:44:29 CET 2008
52 - only assume .cfi pseudo isns exist on GNU/Linux.
53 - add get_timed method to Coro::Channels.
54 - fixed Coro::Debug manpage.
55 - perl 5.11 compatbility improvement based on patch by
56 Andreas König.
57
584.37 Sun Jan 20 11:25:23 CET 2008
59 - soften the check for an active parser for perl 5.10 (avoiding
60 "Coro::State::transfer called while parsing" in many cases).
61
624.36 Sun Jan 13 10:53:56 CET 2008
63 - reset diehook when terminating from an async_pool as to not
64 trigger any __DIE__ handlers.
65
664.35 Sun Jan 13 04:14:13 CET 2008
67 - "bt" debug command now displays any exceptions
68 from longmess and also skips the innermost
69 stackframes, giving more useufl output.
70 - allow backtraces in coroutines blocked in Coro::EV,
71 at a <1% speed hit.
72 - handle localising of $SIG{__WARN__} and __DIE__
73 properly (with a proper amount of dirty hacking).
74
754.34 Sat Dec 22 17:49:53 CET 2007
76 - upgrade to EV version 2.0 API.
77
784.33 Mon Dec 17 08:36:12 CET 2007
79 - make Coro::AIO etc. loadable in the absence of EV.
80
814.32 Mon Dec 17 07:46:02 CET 2007
82 - majorly improved Coro::Handle's performance with Coro::EV.
83 - implemented the until now mythical Coro::BDB module.
84 - specialcase EV in Coro::AIO and Coro::BDB for extra speed.
85
864.31 Wed Dec 5 12:32:39 CET 2007
87 - remove warn statement form Coro::Util.
88
894.3 Tue Dec 4 20:33:14 CET 2007
90 - calls to the idle function could cause stack corruption
91 when the stack changed.
92 - do no longer rely on the presence of EV::DNS if EV is used
93 (because it is gone), but instead take avdantage of EV::ADNS
94 if available.
95 - add ($) prototypes to all functions in Coro::Storable.
96 - use a conventional (safer) idle callback in Coro::EV.
97 - do accept quickly in Coro::Debug to avoid endless loops.
98
994.22 Fri Nov 30 16:04:04 CET 2007
100 - really use optimised versions for Event and EV in Coro::Util
101 and Coro::Handle.
102
1034.21 Sun Nov 25 10:48:59 CET 2007
104 - fix a spurious memory read.
105 - Coro::EV no longer keeps the eventloop "alive".
106
1074.2 Fri Nov 9 20:47:05 CET 2007
108 - enable/disable tracing from a new coroutine, not a pooled one.
109 - fix a memleak in Coro::Event.
110 - removed killall call from fork_eval.
111 - made sure store_fd is already loaded so that fork_eval
112 does not have to parse autoload in each subprocess.
113 - only use assembly method if -O switch is in $Config{optimize}.
114 - add (optional) Coro::EV module, so far the best event loop module
115 directly supported by Coro.
116 - if the event model is EV, use EV::DNS to resolve
117 stuff in Coro::Util.
118 - don't get confused by multiple event notifications in Coro::Handle.
119 - initial support for EV (libevent interface).
120 - require Event and EV using configure_requires, to force their existance.
121
1224.13 Wed Oct 24 07:26:45 CEST 2007
123 - add Coro::Storable::blocking_thaw.
124 - use a vastly more complicated technique to localise
125 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
126 - use a coroutine for the idle callback Coro::Event,
127 instead of running Event in the current coroutine context.
128 This also catches recursive invocations.
129 - actually report fork errors in gethostbyname and inet_aton.
130
1314.11 Thu Oct 11 02:40:24 CEST 2007
132 - port to threaded perls.
133
1344.1 Thu Oct 11 02:38:16 CEST 2007
135 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
136 be local to each coro (see Coro::State).
137 - incompatible change: for very deep reasons, cede and cede_notself
138 cannot return anything, so nothing will be returned.
139 - possibly bring back 5.10 compatibility (untested).
140 - work around stupid (and wrong) warning on 5.10 :(.
141 - overlay the saved state over the context stack. This saves
142 a few hundred bytes per coroutine on average and also
143 speeds up context switching a bit.
144 - further tune default stack sizes.
145 - (more) correctly calculate stack usage in coro_rss.
146 - Coro::Storable::blocking_* did not properly lock
147 resulting in races between coroutines.
148 - added Coro::Storable::guard.
149 - stopping to trace a coroutine could destroy the cctx of
150 an unrelated coroutine.
151 - explain the relationship between Perl and C coroutines in
152 more detail in Coro::State.
153 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
154 causing a fork per resolve. This also affected Coro::Socket.
155 - switch to a separate stack in $coro->call/eval to avoid
156 invalidating pointers.
157
1584.03 Sat Oct 6 21:24:00 CEST 2007
159 - added Coro::throw method.
160 - minor code cleanups.
161
1624.02 Sat Oct 6 02:36:47 CEST 2007
163 - fix a very minor per-coroutine memleak (a single codereference).
164 - fixed a bug where the currently in-use c context would be freed
165 prematurely (can happen only when programs change the stacksize
166 or use tracing).
167 - tracing can no longer keep a coro alive after it terminated.
168 - do static branch prediction in the common path for gcc. gives
169 about 2-5% speed improvement here.

84.01 Fri Oct 5 22:10:49 CEST 2007 1714.01 Fri Oct 5 22:10:49 CEST 2007

10 use STDOUT, which is faster and hopefully more robust. 173 use STDOUT, which is faster and hopefully more robust.
