103.7 84.35 Sun Jan 13 04:14:13 CET 2008
9 - "bt" debug command now displays any exceptions
10 from longmess and also skips the innermost
11 stackframes, giving more useufl output.
12 - allow backtraces in coroutines blocked in Coro::EV,
13 at a <1% speed hit.
14 - handle localising of $SIG{__WARN__} and __DIE__
15 properly (with a proepr amount of dirty hacking).
16
174.34 Sat Dec 22 17:49:53 CET 2007
18 - upgrade to EV version 2.0 API.
19
204.33 Mon Dec 17 08:36:12 CET 2007
21 - make Coro::AIO etc. loadable in the absence of EV.
22
234.32 Mon Dec 17 07:46:02 CET 2007
24 - majorly improved Coro::Handle's performance with Coro::EV.
25 - implemented the until now mythical Coro::BDB module.
26 - specialcase EV in Coro::AIO and Coro::BDB for extra speed.
27
284.31 Wed Dec 5 12:32:39 CET 2007
29 - remove warn statement form Coro::Util.
30
314.3 Tue Dec 4 20:33:14 CET 2007
32 - calls to the idle function could cause stack corruption
33 when the stack changed.
34 - do no longer rely on the presence of EV::DNS if EV is used
35 (because it is gone), but instead take avdantage of EV::ADNS
36 if available.
37 - add ($) prototypes to all functions in Coro::Storable.
38 - use a conventional (safer) idle callback in Coro::EV.
39 - do accept quickly in Coro::Debug to avoid endless loops.
40
414.22 Fri Nov 30 16:04:04 CET 2007
42 - really use optimised versions for Event and EV in Coro::Util
43 and Coro::Handle.
44
454.21 Sun Nov 25 10:48:59 CET 2007
46 - fix a spurious memory read.
47 - Coro::EV no longer keeps the eventloop "alive".
48
494.2 Fri Nov 9 20:47:05 CET 2007
50 - enable/disable tracing from a new coroutine, not a pooled one.
51 - fix a memleak in Coro::Event.
52 - removed killall call from fork_eval.
53 - made sure store_fd is already loaded so that fork_eval
54 does not have to parse autoload in each subprocess.
55 - only use assembly method if -O switch is in $Config{optimize}.
56 - add (optional) Coro::EV module, so far the best event loop module
57 directly supported by Coro.
58 - if the event model is EV, use EV::DNS to resolve
59 stuff in Coro::Util.
60 - don't get confused by multiple event notifications in Coro::Handle.
61 - initial support for EV (libevent interface).
62 - require Event and EV using configure_requires, to force their existance.
63
644.13 Wed Oct 24 07:26:45 CEST 2007
65 - add Coro::Storable::blocking_thaw.
66 - use a vastly more complicated technique to localise
67 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
68 - use a coroutine for the idle callback Coro::Event,
69 instead of running Event in the current coroutine context.
70 This also catches recursive invocations.
71 - actually report fork errors in gethostbyname and inet_aton.
72
734.11 Thu Oct 11 02:40:24 CEST 2007
74 - port to threaded perls.
75
764.1 Thu Oct 11 02:38:16 CEST 2007
77 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
78 be local to each coro (see Coro::State).
79 - incompatible change: for very deep reasons, cede and cede_notself
80 cannot return anything, so nothing will be returned.
81 - possibly bring back 5.10 compatibility (untested).
82 - work around stupid (and wrong) warning on 5.10 :(.
83 - overlay the saved state over the context stack. This saves
84 a few hundred bytes per coroutine on average and also
85 speeds up context switching a bit.
86 - further tune default stack sizes.
87 - (more) correctly calculate stack usage in coro_rss.
88 - Coro::Storable::blocking_* did not properly lock
89 resulting in races between coroutines.
90 - added Coro::Storable::guard.
91 - stopping to trace a coroutine could destroy the cctx of
92 an unrelated coroutine.
93 - explain the relationship between Perl and C coroutines in
94 more detail in Coro::State.
95 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
96 causing a fork per resolve. This also affected Coro::Socket.
97 - switch to a separate stack in $coro->call/eval to avoid
98 invalidating pointers.
99
1004.03 Sat Oct 6 21:24:00 CEST 2007
101 - added Coro::throw method.
102 - minor code cleanups.
103
1044.02 Sat Oct 6 02:36:47 CEST 2007
105 - fix a very minor per-coroutine memleak (a single codereference).
106 - fixed a bug where the currently in-use c context would be freed
107 prematurely (can happen only when programs change the stacksize
108 or use tracing).
109 - tracing can no longer keep a coro alive after it terminated.
110 - do static branch prediction in the common path for gcc. gives
111 about 2-5% speed improvement here.
112
1134.01 Fri Oct 5 22:10:49 CEST 2007
114 - instead of recreating *a* standard output handle we simply
115 use STDOUT, which is faster and hopefully more robust.
116
1174.0 Fri Oct 5 12:56:00 CEST 2007
11 - incompatibly changed Coro::Storable::freeze. 118 - incompatibly changed Coro::Storable::freeze.
12 - added Coro::Debug, interactive coroutine debugging. 119 - major new feature: added Coro::Debug, for interactive coroutine
120 debugging, tracing and much more.
121 - major bug fix: unbelievable, but true: $_, $/ and many other
122 "saved" variables actually weren't being saved. This has been fixed,
123 of course, while increasing performance while losing all the save
124 flags.
125 - save flags are gone, and all the api functions dealing with them.
13 - added Coro::Semaphore::adjust. 126 - added Coro::Semaphore::adjust.
14 - added Coro::Util::fork_eval. 127 - added Coro::Util::fork_eval.
15 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}. 128 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
129 - added Coro::killall.
16 - reduce initial stack sizes to allow for "micro-coroutines". 130 - reduce initial stack sizes to allow for "micro-coroutines".
17 - better async_pool resource management, moved parts of async_pool 131 - better async_pool resource management, moved parts of async_pool
18 handling to XS (major speed improvement). 132 handling to XS (major speed improvement).
133 - actually croak before modifying important data structures.
134 - refuse to transfer while compiling.
135 - possibly support eval EXPR better now.
136 - enable assembly per default on linux+bsd x86+amd64.
137 - all internal members were renamed _something for easier subclassing.
19 - many minor tweaks. 138 - many minor tweaks.

213.63 Wed May 16 14:10:06 CEST 2007 1403.63 Wed May 16 14:10:06 CEST 2007
22 - implement handcoded assembly for x86/amd64 SVR ABI. 141 - implement handcoded assembly for x86/amd64 SVR ABI.
