84.02 84.48 Sun Apr 6 20:36:46 CEST 2008
9 - allow coroutine switches during eval's under 5.10.x, as it seems
10 the parser is a per-interpreter option now, so this is safe
11 (this might fix the odd crashing bug).
12 - drop support for 5.9.x versions: they are dead, jim.
13
144.47 Sun Apr 6 00:37:52 CEST 2008
15 - force cctx allocation on API calls: we know we need to force one
16 and gcc actually manages to confuse our heuristic nowadays,
17 leading to crashes and worse.
18 - document force_cctx.
19
204.46 Fri Apr 4 22:05:43 CEST 2008
21 - upgrade libcoro, resulting in pthread-backend (which was only created
22 to fulfill the rules of the programming languages shootout).
23
244.45 Thu Mar 13 11:55:36 CET 2008
25 - fix a file leaking bug in eg/mhyttpd that would allow
26 downloading of any file (reported by oesi).
27 - fix deadlock bug in Coro::Channel (reported by Richard Hundt)
28 (also add testcase).
29 - support Broadcast option in Coro::Socket (patch by Richard Hundt,
30 apparently having loads of fun with that).
31 - implement $state->swap_defsv, ->swap_defav and document ->throw.
32
334.4 Wed Feb 13 16:44:29 CET 2008
34 - only assume .cfi pseudo isns exist on GNU/Linux.
35 - add get_timed method to Coro::Channels.
36 - fixed Coro::Debug manpage.
37 - perl 5.11 compatbility improvement based on patch by
38 Andreas König.
39
404.37 Sun Jan 20 11:25:23 CET 2008
41 - soften the check for an active parser for perl 5.10 (avoiding
42 "Coro::State::transfer called while parsing" in many cases).
43
444.36 Sun Jan 13 10:53:56 CET 2008
45 - reset diehook when terminating from an async_pool as to not
46 trigger any __DIE__ handlers.
47
484.35 Sun Jan 13 04:14:13 CET 2008
49 - "bt" debug command now displays any exceptions
50 from longmess and also skips the innermost
51 stackframes, giving more useufl output.
52 - allow backtraces in coroutines blocked in Coro::EV,
53 at a <1% speed hit.
54 - handle localising of $SIG{__WARN__} and __DIE__
55 properly (with a proper amount of dirty hacking).
56
574.34 Sat Dec 22 17:49:53 CET 2007
58 - upgrade to EV version 2.0 API.
59
604.33 Mon Dec 17 08:36:12 CET 2007
61 - make Coro::AIO etc. loadable in the absence of EV.
62
634.32 Mon Dec 17 07:46:02 CET 2007
64 - majorly improved Coro::Handle's performance with Coro::EV.
65 - implemented the until now mythical Coro::BDB module.
66 - specialcase EV in Coro::AIO and Coro::BDB for extra speed.
67
684.31 Wed Dec 5 12:32:39 CET 2007
69 - remove warn statement form Coro::Util.
70
714.3 Tue Dec 4 20:33:14 CET 2007
72 - calls to the idle function could cause stack corruption
73 when the stack changed.
74 - do no longer rely on the presence of EV::DNS if EV is used
75 (because it is gone), but instead take avdantage of EV::ADNS
76 if available.
77 - add ($) prototypes to all functions in Coro::Storable.
78 - use a conventional (safer) idle callback in Coro::EV.
79 - do accept quickly in Coro::Debug to avoid endless loops.
80
814.22 Fri Nov 30 16:04:04 CET 2007
82 - really use optimised versions for Event and EV in Coro::Util
83 and Coro::Handle.
84
854.21 Sun Nov 25 10:48:59 CET 2007
86 - fix a spurious memory read.
87 - Coro::EV no longer keeps the eventloop "alive".
88
894.2 Fri Nov 9 20:47:05 CET 2007
90 - enable/disable tracing from a new coroutine, not a pooled one.
91 - fix a memleak in Coro::Event.
92 - removed killall call from fork_eval.
93 - made sure store_fd is already loaded so that fork_eval
94 does not have to parse autoload in each subprocess.
95 - only use assembly method if -O switch is in $Config{optimize}.
96 - add (optional) Coro::EV module, so far the best event loop module
97 directly supported by Coro.
98 - if the event model is EV, use EV::DNS to resolve
99 stuff in Coro::Util.
100 - don't get confused by multiple event notifications in Coro::Handle.
101 - initial support for EV (libevent interface).
102 - require Event and EV using configure_requires, to force their existance.
103
1044.13 Wed Oct 24 07:26:45 CEST 2007
105 - add Coro::Storable::blocking_thaw.
106 - use a vastly more complicated technique to localise
107 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
108 - use a coroutine for the idle callback Coro::Event,
109 instead of running Event in the current coroutine context.
110 This also catches recursive invocations.
111 - actually report fork errors in gethostbyname and inet_aton.
112
1134.11 Thu Oct 11 02:40:24 CEST 2007
114 - port to threaded perls.
115
1164.1 Thu Oct 11 02:38:16 CEST 2007
117 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
118 be local to each coro (see Coro::State).
119 - incompatible change: for very deep reasons, cede and cede_notself
120 cannot return anything, so nothing will be returned.
121 - possibly bring back 5.10 compatibility (untested).
122 - work around stupid (and wrong) warning on 5.10 :(.
123 - overlay the saved state over the context stack. This saves
124 a few hundred bytes per coroutine on average and also
125 speeds up context switching a bit.
126 - further tune default stack sizes.
127 - (more) correctly calculate stack usage in coro_rss.
128 - Coro::Storable::blocking_* did not properly lock
129 resulting in races between coroutines.
130 - added Coro::Storable::guard.
131 - stopping to trace a coroutine could destroy the cctx of
132 an unrelated coroutine.
133 - explain the relationship between Perl and C coroutines in
134 more detail in Coro::State.
135 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
136 causing a fork per resolve. This also affected Coro::Socket.
137 - switch to a separate stack in $coro->call/eval to avoid
138 invalidating pointers.
139
1404.03 Sat Oct 6 21:24:00 CEST 2007
141 - added Coro::throw method.
142 - minor code cleanups.
143
1444.02 Sat Oct 6 02:36:47 CEST 2007
9 - fix a very minor per-coroutine memleak (a single codereference). 145 - fix a very minor per-coroutine memleak (a single codereference).
10 - fixed a bug where the currently in-use c context would be freed 146 - fixed a bug where the currently in-use c context would be freed
11 prematurely (can happen only when programs change the stacksize 147 prematurely (can happen only when programs change the stacksize
12 or use tracing). 148 or use tracing).
13 - tracing can no longer keep a coro alive after it terminated. 149 - tracing can no longer keep a coro alive after it terminated.
150 - do static branch prediction in the common path for gcc. gives
151 about 2-5% speed improvement here.

154.01 Fri Oct 5 22:10:49 CEST 2007 1534.01 Fri Oct 5 22:10:49 CEST 2007

17 use STDOUT, which is faster and hopefully more robust. 155 use STDOUT, which is faster and hopefully more robust.
