84.0 8 - only assume .cfi pseudo isns exist on GNU/Linux.
9
104.37 Sun Jan 20 11:25:23 CET 2008
11 - soften the check for an active parser for perl 5.10 (avoiding
12 "Coro::State::transfer called while parsing" in many cases).
13
144.36 Sun Jan 13 10:53:56 CET 2008
15 - reset diehook when terminating from an async_pool as to not
16 trigger any __DIE__ handlers.
17
184.35 Sun Jan 13 04:14:13 CET 2008
19 - "bt" debug command now displays any exceptions
20 from longmess and also skips the innermost
21 stackframes, giving more useufl output.
22 - allow backtraces in coroutines blocked in Coro::EV,
23 at a <1% speed hit.
24 - handle localising of $SIG{__WARN__} and __DIE__
25 properly (with a proper amount of dirty hacking).
26
274.34 Sat Dec 22 17:49:53 CET 2007
28 - upgrade to EV version 2.0 API.
29
304.33 Mon Dec 17 08:36:12 CET 2007
31 - make Coro::AIO etc. loadable in the absence of EV.
32
334.32 Mon Dec 17 07:46:02 CET 2007
34 - majorly improved Coro::Handle's performance with Coro::EV.
35 - implemented the until now mythical Coro::BDB module.
36 - specialcase EV in Coro::AIO and Coro::BDB for extra speed.
37
384.31 Wed Dec 5 12:32:39 CET 2007
39 - remove warn statement form Coro::Util.
40
414.3 Tue Dec 4 20:33:14 CET 2007
42 - calls to the idle function could cause stack corruption
43 when the stack changed.
44 - do no longer rely on the presence of EV::DNS if EV is used
45 (because it is gone), but instead take avdantage of EV::ADNS
46 if available.
47 - add ($) prototypes to all functions in Coro::Storable.
48 - use a conventional (safer) idle callback in Coro::EV.
49 - do accept quickly in Coro::Debug to avoid endless loops.
50
514.22 Fri Nov 30 16:04:04 CET 2007
52 - really use optimised versions for Event and EV in Coro::Util
53 and Coro::Handle.
54
554.21 Sun Nov 25 10:48:59 CET 2007
56 - fix a spurious memory read.
57 - Coro::EV no longer keeps the eventloop "alive".
58
594.2 Fri Nov 9 20:47:05 CET 2007
60 - enable/disable tracing from a new coroutine, not a pooled one.
61 - fix a memleak in Coro::Event.
62 - removed killall call from fork_eval.
63 - made sure store_fd is already loaded so that fork_eval
64 does not have to parse autoload in each subprocess.
65 - only use assembly method if -O switch is in $Config{optimize}.
66 - add (optional) Coro::EV module, so far the best event loop module
67 directly supported by Coro.
68 - if the event model is EV, use EV::DNS to resolve
69 stuff in Coro::Util.
70 - don't get confused by multiple event notifications in Coro::Handle.
71 - initial support for EV (libevent interface).
72 - require Event and EV using configure_requires, to force their existance.
73
744.13 Wed Oct 24 07:26:45 CEST 2007
75 - add Coro::Storable::blocking_thaw.
76 - use a vastly more complicated technique to localise
77 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
78 - use a coroutine for the idle callback Coro::Event,
79 instead of running Event in the current coroutine context.
80 This also catches recursive invocations.
81 - actually report fork errors in gethostbyname and inet_aton.
82
834.11 Thu Oct 11 02:40:24 CEST 2007
84 - port to threaded perls.
85
864.1 Thu Oct 11 02:38:16 CEST 2007
87 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
88 be local to each coro (see Coro::State).
89 - incompatible change: for very deep reasons, cede and cede_notself
90 cannot return anything, so nothing will be returned.
91 - possibly bring back 5.10 compatibility (untested).
92 - work around stupid (and wrong) warning on 5.10 :(.
93 - overlay the saved state over the context stack. This saves
94 a few hundred bytes per coroutine on average and also
95 speeds up context switching a bit.
96 - further tune default stack sizes.
97 - (more) correctly calculate stack usage in coro_rss.
98 - Coro::Storable::blocking_* did not properly lock
99 resulting in races between coroutines.
100 - added Coro::Storable::guard.
101 - stopping to trace a coroutine could destroy the cctx of
102 an unrelated coroutine.
103 - explain the relationship between Perl and C coroutines in
104 more detail in Coro::State.
105 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
106 causing a fork per resolve. This also affected Coro::Socket.
107 - switch to a separate stack in $coro->call/eval to avoid
108 invalidating pointers.
109
1104.03 Sat Oct 6 21:24:00 CEST 2007
111 - added Coro::throw method.
112 - minor code cleanups.
113
1144.02 Sat Oct 6 02:36:47 CEST 2007
115 - fix a very minor per-coroutine memleak (a single codereference).
116 - fixed a bug where the currently in-use c context would be freed
117 prematurely (can happen only when programs change the stacksize
118 or use tracing).
119 - tracing can no longer keep a coro alive after it terminated.
120 - do static branch prediction in the common path for gcc. gives
121 about 2-5% speed improvement here.
122
1234.01 Fri Oct 5 22:10:49 CEST 2007
124 - instead of recreating *a* standard output handle we simply
125 use STDOUT, which is faster and hopefully more robust.
126
1274.0 Fri Oct 5 12:56:00 CEST 2007
