84.02 8 - INCOMPATIBLE CHANGE: sub/code attributes are no longer supported
9 by the Coro module. It was a mistake.
10 - (experimental) support for activestate perl 5.10.
11 - coro_sigelem_set did not return a value although it had to,
12 actual impact unknown.
13
144.51 Mon Apr 14 13:28:27 CEST 2008
15 - make it compile again on 5.8.
16
174.50 Thu Apr 10 09:43:17 CEST 2008
18 - I did it twice! (see 4.49).
19
204.49 Sun Apr 6 21:23:31 CEST 2008
21 - grr, instead of compiling the recent changes on 5.10 only they
22 were compiled on 5.8 only.
23
244.48 Sun Apr 6 20:36:46 CEST 2008
25 - allow coroutine switches during eval's under 5.10.x, as it seems
26 the parser is a per-interpreter option now, so this is safe
27 (this might fix the odd crashing bug).
28 - drop support for 5.9.x versions: they are dead, jim.
29
304.47 Sun Apr 6 00:37:52 CEST 2008
31 - force cctx allocation on API calls: we know we need to force one
32 and gcc actually manages to confuse our heuristic nowadays,
33 leading to crashes and worse.
34 - document force_cctx.
35
364.46 Fri Apr 4 22:05:43 CEST 2008
37 - upgrade libcoro, resulting in pthread-backend (which was only created
38 to fulfill the rules of the programming languages shootout).
39
404.45 Thu Mar 13 11:55:36 CET 2008
41 - fix a file leaking bug in eg/mhyttpd that would allow
42 downloading of any file (reported by oesi).
43 - fix deadlock bug in Coro::Channel (reported by Richard Hundt)
44 (also add testcase).
45 - support Broadcast option in Coro::Socket (patch by Richard Hundt,
46 apparently having loads of fun with that).
47 - implement $state->swap_defsv, ->swap_defav and document ->throw.
48
494.4 Wed Feb 13 16:44:29 CET 2008
50 - only assume .cfi pseudo isns exist on GNU/Linux.
51 - add get_timed method to Coro::Channels.
52 - fixed Coro::Debug manpage.
53 - perl 5.11 compatbility improvement based on patch by
54 Andreas König.
55
564.37 Sun Jan 20 11:25:23 CET 2008
57 - soften the check for an active parser for perl 5.10 (avoiding
58 "Coro::State::transfer called while parsing" in many cases).
59
604.36 Sun Jan 13 10:53:56 CET 2008
61 - reset diehook when terminating from an async_pool as to not
62 trigger any __DIE__ handlers.
63
644.35 Sun Jan 13 04:14:13 CET 2008
65 - "bt" debug command now displays any exceptions
66 from longmess and also skips the innermost
67 stackframes, giving more useufl output.
68 - allow backtraces in coroutines blocked in Coro::EV,
69 at a <1% speed hit.
70 - handle localising of $SIG{__WARN__} and __DIE__
71 properly (with a proper amount of dirty hacking).
72
734.34 Sat Dec 22 17:49:53 CET 2007
74 - upgrade to EV version 2.0 API.
75
764.33 Mon Dec 17 08:36:12 CET 2007
77 - make Coro::AIO etc. loadable in the absence of EV.
78
794.32 Mon Dec 17 07:46:02 CET 2007
80 - majorly improved Coro::Handle's performance with Coro::EV.
81 - implemented the until now mythical Coro::BDB module.
82 - specialcase EV in Coro::AIO and Coro::BDB for extra speed.
83
844.31 Wed Dec 5 12:32:39 CET 2007
85 - remove warn statement form Coro::Util.
86
874.3 Tue Dec 4 20:33:14 CET 2007
88 - calls to the idle function could cause stack corruption
89 when the stack changed.
90 - do no longer rely on the presence of EV::DNS if EV is used
91 (because it is gone), but instead take avdantage of EV::ADNS
92 if available.
93 - add ($) prototypes to all functions in Coro::Storable.
94 - use a conventional (safer) idle callback in Coro::EV.
95 - do accept quickly in Coro::Debug to avoid endless loops.
96
974.22 Fri Nov 30 16:04:04 CET 2007
98 - really use optimised versions for Event and EV in Coro::Util
99 and Coro::Handle.
100
1014.21 Sun Nov 25 10:48:59 CET 2007
102 - fix a spurious memory read.
103 - Coro::EV no longer keeps the eventloop "alive".
104
1054.2 Fri Nov 9 20:47:05 CET 2007
106 - enable/disable tracing from a new coroutine, not a pooled one.
107 - fix a memleak in Coro::Event.
108 - removed killall call from fork_eval.
109 - made sure store_fd is already loaded so that fork_eval
110 does not have to parse autoload in each subprocess.
111 - only use assembly method if -O switch is in $Config{optimize}.
112 - add (optional) Coro::EV module, so far the best event loop module
113 directly supported by Coro.
114 - if the event model is EV, use EV::DNS to resolve
115 stuff in Coro::Util.
116 - don't get confused by multiple event notifications in Coro::Handle.
117 - initial support for EV (libevent interface).
118 - require Event and EV using configure_requires, to force their existance.
119
1204.13 Wed Oct 24 07:26:45 CEST 2007
121 - add Coro::Storable::blocking_thaw.
122 - use a vastly more complicated technique to localise
123 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
124 - use a coroutine for the idle callback Coro::Event,
125 instead of running Event in the current coroutine context.
126 This also catches recursive invocations.
127 - actually report fork errors in gethostbyname and inet_aton.
128
1294.11 Thu Oct 11 02:40:24 CEST 2007
130 - port to threaded perls.
131
1324.1 Thu Oct 11 02:38:16 CEST 2007
133 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
134 be local to each coro (see Coro::State).
135 - incompatible change: for very deep reasons, cede and cede_notself
136 cannot return anything, so nothing will be returned.
137 - possibly bring back 5.10 compatibility (untested).
138 - work around stupid (and wrong) warning on 5.10 :(.
139 - overlay the saved state over the context stack. This saves
140 a few hundred bytes per coroutine on average and also
141 speeds up context switching a bit.
142 - further tune default stack sizes.
143 - (more) correctly calculate stack usage in coro_rss.
144 - Coro::Storable::blocking_* did not properly lock
145 resulting in races between coroutines.
146 - added Coro::Storable::guard.
147 - stopping to trace a coroutine could destroy the cctx of
148 an unrelated coroutine.
149 - explain the relationship between Perl and C coroutines in
150 more detail in Coro::State.
151 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
152 causing a fork per resolve. This also affected Coro::Socket.
153 - switch to a separate stack in $coro->call/eval to avoid
154 invalidating pointers.
155
1564.03 Sat Oct 6 21:24:00 CEST 2007
157 - added Coro::throw method.
158 - minor code cleanups.
159
1604.02 Sat Oct 6 02:36:47 CEST 2007
9 - fix a very minor per-coroutine memleak (a single codereference). 161 - fix a very minor per-coroutine memleak (a single codereference).
10 - fixed a bug where the currently in-use c context would be freed 162 - fixed a bug where the currently in-use c context would be freed
11 prematurely (can happen only when programs change the stacksize 163 prematurely (can happen only when programs change the stacksize
12 or use tracing). 164 or use tracing).
13 - tracing can no longer keep a coro alive after it terminated. 165 - tracing can no longer keep a coro alive after it terminated.
