9 7
103.7 84.37
11 - added Coro::Debug, interactive coroutine debugging. 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
125 - incompatibly changed Coro::Storable::freeze.
126 - major new feature: added Coro::Debug, for interactive coroutine
127 debugging, tracing and much more.
128 - major bug fix: unbelievable, but true: $_, $/ and many other
129 "saved" variables actually weren't being saved. This has been fixed,
130 of course, while increasing performance while losing all the save
131 flags.
132 - save flags are gone, and all the api functions dealing with them.
12 - added Coro::Semaphore::adjust. 133 - added Coro::Semaphore::adjust.
13 - added Coro::Util::fork_eval. 134 - added Coro::Util::fork_eval.
14 - incompatibly changed Coro::Storable::freeze.
15 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}. 135 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
136 - added Coro::killall.
16 - reduce initial stack sizes to allow for "micro-coroutines". 137 - reduce initial stack sizes to allow for "micro-coroutines".
138 - better async_pool resource management, moved parts of async_pool
139 handling to XS (major speed improvement).
140 - actually croak before modifying important data structures.
141 - refuse to transfer while compiling.
142 - possibly support eval EXPR better now.
143 - enable assembly per default on linux+bsd x86+amd64.
144 - all internal members were renamed _something for easier subclassing.
17 - many minor tweaks. 145 - many minor tweaks.

193.63 Wed May 16 14:10:06 CEST 2007 1473.63 Wed May 16 14:10:06 CEST 2007
20 - implement handcoded assembly for x86/amd64 SVR ABI. 148 - implement handcoded assembly for x86/amd64 SVR ABI.
