84.4
9 - only assume .cfi pseudo isns exist on GNU/Linux.
10 - add get_timed method to Coro::Channels.
11
124.37 Sun Jan 20 11:25:23 CET 2008
13 - soften the check for an active parser for perl 5.10 (avoiding
14 "Coro::State::transfer called while parsing" in many cases).
15
164.36 Sun Jan 13 10:53:56 CET 2008
17 - reset diehook when terminating from an async_pool as to not
18 trigger any __DIE__ handlers.
19
204.35 Sun Jan 13 04:14:13 CET 2008
21 - "bt" debug command now displays any exceptions
22 from longmess and also skips the innermost
23 stackframes, giving more useufl output.
24 - allow backtraces in coroutines blocked in Coro::EV,
25 at a <1% speed hit.
26 - handle localising of $SIG{__WARN__} and __DIE__
27 properly (with a proper amount of dirty hacking).
28
294.34 Sat Dec 22 17:49:53 CET 2007
30 - upgrade to EV version 2.0 API.
31
324.33 Mon Dec 17 08:36:12 CET 2007
33 - make Coro::AIO etc. loadable in the absence of EV.
34
354.32 Mon Dec 17 07:46:02 CET 2007
36 - majorly improved Coro::Handle's performance with Coro::EV.
37 - implemented the until now mythical Coro::BDB module.
38 - specialcase EV in Coro::AIO and Coro::BDB for extra speed.
39
404.31 Wed Dec 5 12:32:39 CET 2007
41 - remove warn statement form Coro::Util.
42
434.3 Tue Dec 4 20:33:14 CET 2007
44 - calls to the idle function could cause stack corruption
45 when the stack changed.
46 - do no longer rely on the presence of EV::DNS if EV is used
47 (because it is gone), but instead take avdantage of EV::ADNS
48 if available.
49 - add ($) prototypes to all functions in Coro::Storable.
50 - use a conventional (safer) idle callback in Coro::EV.
51 - do accept quickly in Coro::Debug to avoid endless loops.
52
534.22 Fri Nov 30 16:04:04 CET 2007
54 - really use optimised versions for Event and EV in Coro::Util
55 and Coro::Handle.
56
574.21 Sun Nov 25 10:48:59 CET 2007
58 - fix a spurious memory read.
59 - Coro::EV no longer keeps the eventloop "alive".
60
614.2 Fri Nov 9 20:47:05 CET 2007
62 - enable/disable tracing from a new coroutine, not a pooled one.
63 - fix a memleak in Coro::Event.
64 - removed killall call from fork_eval.
65 - made sure store_fd is already loaded so that fork_eval
66 does not have to parse autoload in each subprocess.
67 - only use assembly method if -O switch is in $Config{optimize}.
68 - add (optional) Coro::EV module, so far the best event loop module
69 directly supported by Coro.
70 - if the event model is EV, use EV::DNS to resolve
71 stuff in Coro::Util.
72 - don't get confused by multiple event notifications in Coro::Handle.
73 - initial support for EV (libevent interface).
74 - require Event and EV using configure_requires, to force their existance.
75
764.13 Wed Oct 24 07:26:45 CEST 2007
77 - add Coro::Storable::blocking_thaw.
78 - use a vastly more complicated technique to localise
79 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
80 - use a coroutine for the idle callback Coro::Event,
81 instead of running Event in the current coroutine context.
82 This also catches recursive invocations.
83 - actually report fork errors in gethostbyname and inet_aton.
84
854.11 Thu Oct 11 02:40:24 CEST 2007
86 - port to threaded perls.
87
884.1 Thu Oct 11 02:38:16 CEST 2007
89 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
90 be local to each coro (see Coro::State).
91 - incompatible change: for very deep reasons, cede and cede_notself
92 cannot return anything, so nothing will be returned.
93 - possibly bring back 5.10 compatibility (untested).
94 - work around stupid (and wrong) warning on 5.10 :(.
95 - overlay the saved state over the context stack. This saves
96 a few hundred bytes per coroutine on average and also
97 speeds up context switching a bit.
98 - further tune default stack sizes.
99 - (more) correctly calculate stack usage in coro_rss.
100 - Coro::Storable::blocking_* did not properly lock
101 resulting in races between coroutines.
102 - added Coro::Storable::guard.
103 - stopping to trace a coroutine could destroy the cctx of
104 an unrelated coroutine.
105 - explain the relationship between Perl and C coroutines in
106 more detail in Coro::State.
107 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
108 causing a fork per resolve. This also affected Coro::Socket.
109 - switch to a separate stack in $coro->call/eval to avoid
110 invalidating pointers.
111
1124.03 Sat Oct 6 21:24:00 CEST 2007
113 - added Coro::throw method.
114 - minor code cleanups.
115
1164.02 Sat Oct 6 02:36:47 CEST 2007
117 - fix a very minor per-coroutine memleak (a single codereference).
118 - fixed a bug where the currently in-use c context would be freed
119 prematurely (can happen only when programs change the stacksize
120 or use tracing).
121 - tracing can no longer keep a coro alive after it terminated.
122 - do static branch prediction in the common path for gcc. gives
123 about 2-5% speed improvement here.
124
1254.01 Fri Oct 5 22:10:49 CEST 2007
126 - instead of recreating *a* standard output handle we simply
127 use STDOUT, which is faster and hopefully more robust.
128
1294.0 Fri Oct 5 12:56:00 CEST 2007
130 - incompatibly changed Coro::Storable::freeze.
131 - major new feature: added Coro::Debug, for interactive coroutine
132 debugging, tracing and much more.
133 - major bug fix: unbelievable, but true: $_, $/ and many other
134 "saved" variables actually weren't being saved. This has been fixed,
135 of course, while increasing performance while losing all the save
136 flags.
137 - save flags are gone, and all the api functions dealing with them.
138 - added Coro::Semaphore::adjust.
139 - added Coro::Util::fork_eval.
140 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
141 - added Coro::killall.
142 - reduce initial stack sizes to allow for "micro-coroutines".
143 - better async_pool resource management, moved parts of async_pool
144 handling to XS (major speed improvement).
145 - actually croak before modifying important data structures.
146 - refuse to transfer while compiling.
147 - possibly support eval EXPR better now.
148 - enable assembly per default on linux+bsd x86+amd64.
149 - all internal members were renamed _something for easier subclassing.
150 - many minor tweaks.
151
1523.63 Wed May 16 14:10:06 CEST 2007
153 - implement handcoded assembly for x86/amd64 SVR ABI.
154
1553.62 Fri Apr 27 21:36:06 CEST 2007
10 - upgrade libcoro (which might set unwidn info correctly). 156 - upgrade libcoro (which might set unwind info correctly).
11 - change default on linux to setjmp/longjmp. 157 - change default on linux to setjmp/longjmp.
