9 - grr, instead of compiling the recent changes on 5.10 only they
10 were compiled on 5.8 only.
11
124.48 Sun Apr 6 20:36:46 CEST 2008
13 - allow coroutine switches during eval's under 5.10.x, as it seems
14 the parser is a per-interpreter option now, so this is safe
15 (this might fix the odd crashing bug).
16 - drop support for 5.9.x versions: they are dead, jim.
17
184.47 Sun Apr 6 00:37:52 CEST 2008
19 - force cctx allocation on API calls: we know we need to force one
20 and gcc actually manages to confuse our heuristic nowadays,
21 leading to crashes and worse.
22 - document force_cctx.
23
244.46 Fri Apr 4 22:05:43 CEST 2008
25 - upgrade libcoro, resulting in pthread-backend (which was only created
26 to fulfill the rules of the programming languages shootout).
27
284.45 Thu Mar 13 11:55:36 CET 2008
29 - fix a file leaking bug in eg/mhyttpd that would allow
30 downloading of any file (reported by oesi).
31 - fix deadlock bug in Coro::Channel (reported by Richard Hundt)
32 (also add testcase).
33 - support Broadcast option in Coro::Socket (patch by Richard Hundt,
34 apparently having loads of fun with that).
35 - implement $state->swap_defsv, ->swap_defav and document ->throw.
36
374.4 Wed Feb 13 16:44:29 CET 2008
38 - only assume .cfi pseudo isns exist on GNU/Linux.
39 - add get_timed method to Coro::Channels.
40 - fixed Coro::Debug manpage.
41 - perl 5.11 compatbility improvement based on patch by
42 Andreas König.
43
444.37 Sun Jan 20 11:25:23 CET 2008
45 - soften the check for an active parser for perl 5.10 (avoiding
46 "Coro::State::transfer called while parsing" in many cases).
47
484.36 Sun Jan 13 10:53:56 CET 2008
49 - reset diehook when terminating from an async_pool as to not
50 trigger any __DIE__ handlers.
51
524.35 Sun Jan 13 04:14:13 CET 2008
53 - "bt" debug command now displays any exceptions
54 from longmess and also skips the innermost
55 stackframes, giving more useufl output.
56 - allow backtraces in coroutines blocked in Coro::EV,
57 at a <1% speed hit.
58 - handle localising of $SIG{__WARN__} and __DIE__
59 properly (with a proper amount of dirty hacking).
60
614.34 Sat Dec 22 17:49:53 CET 2007
62 - upgrade to EV version 2.0 API.
63
644.33 Mon Dec 17 08:36:12 CET 2007
65 - make Coro::AIO etc. loadable in the absence of EV.
66
674.32 Mon Dec 17 07:46:02 CET 2007
68 - majorly improved Coro::Handle's performance with Coro::EV.
69 - implemented the until now mythical Coro::BDB module.
70 - specialcase EV in Coro::AIO and Coro::BDB for extra speed.
71
724.31 Wed Dec 5 12:32:39 CET 2007
73 - remove warn statement form Coro::Util.
74
754.3 Tue Dec 4 20:33:14 CET 2007
76 - calls to the idle function could cause stack corruption
77 when the stack changed.
78 - do no longer rely on the presence of EV::DNS if EV is used
79 (because it is gone), but instead take avdantage of EV::ADNS
80 if available.
81 - add ($) prototypes to all functions in Coro::Storable.
82 - use a conventional (safer) idle callback in Coro::EV.
83 - do accept quickly in Coro::Debug to avoid endless loops.
84
854.22 Fri Nov 30 16:04:04 CET 2007
86 - really use optimised versions for Event and EV in Coro::Util
87 and Coro::Handle.
88
894.21 Sun Nov 25 10:48:59 CET 2007
90 - fix a spurious memory read.
91 - Coro::EV no longer keeps the eventloop "alive".
92
934.2 Fri Nov 9 20:47:05 CET 2007
94 - enable/disable tracing from a new coroutine, not a pooled one.
95 - fix a memleak in Coro::Event.
96 - removed killall call from fork_eval.
97 - made sure store_fd is already loaded so that fork_eval
98 does not have to parse autoload in each subprocess.
99 - only use assembly method if -O switch is in $Config{optimize}.
100 - add (optional) Coro::EV module, so far the best event loop module
101 directly supported by Coro.
102 - if the event model is EV, use EV::DNS to resolve
103 stuff in Coro::Util.
104 - don't get confused by multiple event notifications in Coro::Handle.
105 - initial support for EV (libevent interface).
106 - require Event and EV using configure_requires, to force their existance.
107
1084.13 Wed Oct 24 07:26:45 CEST 2007
109 - add Coro::Storable::blocking_thaw.
110 - use a vastly more complicated technique to localise
111 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
112 - use a coroutine for the idle callback Coro::Event,
113 instead of running Event in the current coroutine context.
114 This also catches recursive invocations.
115 - actually report fork errors in gethostbyname and inet_aton.
116
1174.11 Thu Oct 11 02:40:24 CEST 2007
118 - port to threaded perls.
119
1204.1 Thu Oct 11 02:38:16 CEST 2007
9 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now 121 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
10 be local to each coro (see Coro::State). 122 be local to each coro (see Coro::State).
123 - incompatible change: for very deep reasons, cede and cede_notself
124 cannot return anything, so nothing will be returned.
11 - possibly bring back 5.10 compatibility (untested). 125 - possibly bring back 5.10 compatibility (untested).
12 - work around stupid (and wrong) warning on 5.10 :(. 126 - work around stupid (and wrong) warning on 5.10 :(.
13 - overlay the saved state over the context stack. This saves 127 - overlay the saved state over the context stack. This saves
14 a few hundred bytes per coroutine on average and also 128 a few hundred bytes per coroutine on average and also
15 speeds up context switching a bit. 129 speeds up context switching a bit.
16 - further tune default stack sizes. 130 - further tune default stack sizes.
17 - (more) correctly calculate stack usage in coro_rss. 131 - (more) correctly calculate stack usage in coro_rss.
132 - Coro::Storable::blocking_* did not properly lock
133 resulting in races between coroutines.
134 - added Coro::Storable::guard.
135 - stopping to trace a coroutine could destroy the cctx of
136 an unrelated coroutine.
137 - explain the relationship between Perl and C coroutines in
138 more detail in Coro::State.
139 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
140 causing a fork per resolve. This also affected Coro::Socket.
141 - switch to a separate stack in $coro->call/eval to avoid
142 invalidating pointers.

194.03 Sat Oct 6 21:24:00 CEST 2007 1444.03 Sat Oct 6 21:24:00 CEST 2007
20 - added Coro::throw method. 145 - added Coro::throw method.
