84.0 84.37
9 - soften the check for an active parser for perl 5.10.
10
114.36 Sun Jan 13 10:53:56 CET 2008
12 - reset diehook when terminating from an async_pool as to not
13 trigger any __DIE__ handlers.
14
154.35 Sun Jan 13 04:14:13 CET 2008
16 - "bt" debug command now displays any exceptions
17 from longmess and also skips the innermost
18 stackframes, giving more useufl output.
19 - allow backtraces in coroutines blocked in Coro::EV,
20 at a <1% speed hit.
21 - handle localising of $SIG{__WARN__} and __DIE__
22 properly (with a proper amount of dirty hacking).
23
244.34 Sat Dec 22 17:49:53 CET 2007
25 - upgrade to EV version 2.0 API.
26
274.33 Mon Dec 17 08:36:12 CET 2007
28 - make Coro::AIO etc. loadable in the absence of EV.
29
304.32 Mon Dec 17 07:46:02 CET 2007
31 - majorly improved Coro::Handle's performance with Coro::EV.
32 - implemented the until now mythical Coro::BDB module.
33 - specialcase EV in Coro::AIO and Coro::BDB for extra speed.
34
354.31 Wed Dec 5 12:32:39 CET 2007
36 - remove warn statement form Coro::Util.
37
384.3 Tue Dec 4 20:33:14 CET 2007
39 - calls to the idle function could cause stack corruption
40 when the stack changed.
41 - do no longer rely on the presence of EV::DNS if EV is used
42 (because it is gone), but instead take avdantage of EV::ADNS
43 if available.
44 - add ($) prototypes to all functions in Coro::Storable.
45 - use a conventional (safer) idle callback in Coro::EV.
46 - do accept quickly in Coro::Debug to avoid endless loops.
47
484.22 Fri Nov 30 16:04:04 CET 2007
49 - really use optimised versions for Event and EV in Coro::Util
50 and Coro::Handle.
51
524.21 Sun Nov 25 10:48:59 CET 2007
53 - fix a spurious memory read.
54 - Coro::EV no longer keeps the eventloop "alive".
55
564.2 Fri Nov 9 20:47:05 CET 2007
57 - enable/disable tracing from a new coroutine, not a pooled one.
58 - fix a memleak in Coro::Event.
59 - removed killall call from fork_eval.
60 - made sure store_fd is already loaded so that fork_eval
61 does not have to parse autoload in each subprocess.
62 - only use assembly method if -O switch is in $Config{optimize}.
63 - add (optional) Coro::EV module, so far the best event loop module
64 directly supported by Coro.
65 - if the event model is EV, use EV::DNS to resolve
66 stuff in Coro::Util.
67 - don't get confused by multiple event notifications in Coro::Handle.
68 - initial support for EV (libevent interface).
69 - require Event and EV using configure_requires, to force their existance.
70
714.13 Wed Oct 24 07:26:45 CEST 2007
72 - add Coro::Storable::blocking_thaw.
73 - use a vastly more complicated technique to localise
74 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
75 - use a coroutine for the idle callback Coro::Event,
76 instead of running Event in the current coroutine context.
77 This also catches recursive invocations.
78 - actually report fork errors in gethostbyname and inet_aton.
79
804.11 Thu Oct 11 02:40:24 CEST 2007
81 - port to threaded perls.
82
834.1 Thu Oct 11 02:38:16 CEST 2007
84 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
85 be local to each coro (see Coro::State).
86 - incompatible change: for very deep reasons, cede and cede_notself
87 cannot return anything, so nothing will be returned.
88 - possibly bring back 5.10 compatibility (untested).
89 - work around stupid (and wrong) warning on 5.10 :(.
90 - overlay the saved state over the context stack. This saves
91 a few hundred bytes per coroutine on average and also
92 speeds up context switching a bit.
93 - further tune default stack sizes.
94 - (more) correctly calculate stack usage in coro_rss.
95 - Coro::Storable::blocking_* did not properly lock
96 resulting in races between coroutines.
97 - added Coro::Storable::guard.
98 - stopping to trace a coroutine could destroy the cctx of
99 an unrelated coroutine.
100 - explain the relationship between Perl and C coroutines in
101 more detail in Coro::State.
102 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
103 causing a fork per resolve. This also affected Coro::Socket.
104 - switch to a separate stack in $coro->call/eval to avoid
105 invalidating pointers.
106
1074.03 Sat Oct 6 21:24:00 CEST 2007
108 - added Coro::throw method.
109 - minor code cleanups.
110
1114.02 Sat Oct 6 02:36:47 CEST 2007
112 - fix a very minor per-coroutine memleak (a single codereference).
113 - fixed a bug where the currently in-use c context would be freed
114 prematurely (can happen only when programs change the stacksize
115 or use tracing).
116 - tracing can no longer keep a coro alive after it terminated.
117 - do static branch prediction in the common path for gcc. gives
118 about 2-5% speed improvement here.
119
1204.01 Fri Oct 5 22:10:49 CEST 2007
121 - instead of recreating *a* standard output handle we simply
122 use STDOUT, which is faster and hopefully more robust.
123
1244.0 Fri Oct 5 12:56:00 CEST 2007
9 - incompatibly changed Coro::Storable::freeze. 125 - incompatibly changed Coro::Storable::freeze.
10 - major new feature: added Coro::Debug, for interactive coroutine 126 - major new feature: added Coro::Debug, for interactive coroutine
11 debugging, tracing and much more. 127 debugging, tracing and much more.
12 - unbelievable, but true: $_, $@ and many other "saved" variables 128 - major bug fix: unbelievable, but true: $_, $/ and many other
13 actually weren't being saved. This has been fixed, of course, 129 "saved" variables actually weren't being saved. This has been fixed,
14 while increasing performance while losing all the save flags. 130 of course, while increasing performance while losing all the save
131 flags.
15 - save flags are gone, and all the api functions dealing with them. 132 - save flags are gone, and all the api functions dealing with them.
16 - added Coro::Semaphore::adjust. 133 - added Coro::Semaphore::adjust.
17 - added Coro::Util::fork_eval. 134 - added Coro::Util::fork_eval.
18 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}. 135 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
