103.8 84.37
9 - soften the check for an active parser for perl 5.10 (avoiding
10 "Coro::State::transfer called while parsing" in many cases).
11
124.36 Sun Jan 13 10:53:56 CET 2008
13 - reset diehook when terminating from an async_pool as to not
14 trigger any __DIE__ handlers.
15
164.35 Sun Jan 13 04:14:13 CET 2008
17 - "bt" debug command now displays any exceptions
18 from longmess and also skips the innermost
19 stackframes, giving more useufl output.
20 - allow backtraces in coroutines blocked in Coro::EV,
21 at a <1% speed hit.
22 - handle localising of $SIG{__WARN__} and __DIE__
23 properly (with a proper amount of dirty hacking).
24
254.34 Sat Dec 22 17:49:53 CET 2007
26 - upgrade to EV version 2.0 API.
27
284.33 Mon Dec 17 08:36:12 CET 2007
29 - make Coro::AIO etc. loadable in the absence of EV.
30
314.32 Mon Dec 17 07:46:02 CET 2007
32 - majorly improved Coro::Handle's performance with Coro::EV.
33 - implemented the until now mythical Coro::BDB module.
34 - specialcase EV in Coro::AIO and Coro::BDB for extra speed.
35
364.31 Wed Dec 5 12:32:39 CET 2007
37 - remove warn statement form Coro::Util.
38
394.3 Tue Dec 4 20:33:14 CET 2007
40 - calls to the idle function could cause stack corruption
41 when the stack changed.
42 - do no longer rely on the presence of EV::DNS if EV is used
43 (because it is gone), but instead take avdantage of EV::ADNS
44 if available.
45 - add ($) prototypes to all functions in Coro::Storable.
46 - use a conventional (safer) idle callback in Coro::EV.
47 - do accept quickly in Coro::Debug to avoid endless loops.
48
494.22 Fri Nov 30 16:04:04 CET 2007
50 - really use optimised versions for Event and EV in Coro::Util
51 and Coro::Handle.
52
534.21 Sun Nov 25 10:48:59 CET 2007
54 - fix a spurious memory read.
55 - Coro::EV no longer keeps the eventloop "alive".
56
574.2 Fri Nov 9 20:47:05 CET 2007
58 - enable/disable tracing from a new coroutine, not a pooled one.
59 - fix a memleak in Coro::Event.
60 - removed killall call from fork_eval.
61 - made sure store_fd is already loaded so that fork_eval
62 does not have to parse autoload in each subprocess.
63 - only use assembly method if -O switch is in $Config{optimize}.
64 - add (optional) Coro::EV module, so far the best event loop module
65 directly supported by Coro.
66 - if the event model is EV, use EV::DNS to resolve
67 stuff in Coro::Util.
68 - don't get confused by multiple event notifications in Coro::Handle.
69 - initial support for EV (libevent interface).
70 - require Event and EV using configure_requires, to force their existance.
71
724.13 Wed Oct 24 07:26:45 CEST 2007
73 - add Coro::Storable::blocking_thaw.
74 - use a vastly more complicated technique to localise
75 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
76 - use a coroutine for the idle callback Coro::Event,
77 instead of running Event in the current coroutine context.
78 This also catches recursive invocations.
79 - actually report fork errors in gethostbyname and inet_aton.
80
814.11 Thu Oct 11 02:40:24 CEST 2007
82 - port to threaded perls.
83
844.1 Thu Oct 11 02:38:16 CEST 2007
85 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
86 be local to each coro (see Coro::State).
87 - incompatible change: for very deep reasons, cede and cede_notself
88 cannot return anything, so nothing will be returned.
89 - possibly bring back 5.10 compatibility (untested).
90 - work around stupid (and wrong) warning on 5.10 :(.
91 - overlay the saved state over the context stack. This saves
92 a few hundred bytes per coroutine on average and also
93 speeds up context switching a bit.
94 - further tune default stack sizes.
95 - (more) correctly calculate stack usage in coro_rss.
96 - Coro::Storable::blocking_* did not properly lock
97 resulting in races between coroutines.
98 - added Coro::Storable::guard.
99 - stopping to trace a coroutine could destroy the cctx of
100 an unrelated coroutine.
101 - explain the relationship between Perl and C coroutines in
102 more detail in Coro::State.
103 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
104 causing a fork per resolve. This also affected Coro::Socket.
105 - switch to a separate stack in $coro->call/eval to avoid
106 invalidating pointers.
107
1084.03 Sat Oct 6 21:24:00 CEST 2007
109 - added Coro::throw method.
110 - minor code cleanups.
111
1124.02 Sat Oct 6 02:36:47 CEST 2007
113 - fix a very minor per-coroutine memleak (a single codereference).
114 - fixed a bug where the currently in-use c context would be freed
115 prematurely (can happen only when programs change the stacksize
116 or use tracing).
117 - tracing can no longer keep a coro alive after it terminated.
118 - do static branch prediction in the common path for gcc. gives
119 about 2-5% speed improvement here.
120
1214.01 Fri Oct 5 22:10:49 CEST 2007
122 - instead of recreating *a* standard output handle we simply
123 use STDOUT, which is faster and hopefully more robust.
124
1254.0 Fri Oct 5 12:56:00 CEST 2007
11 - incompatibly changed Coro::Storable::freeze. 126 - incompatibly changed Coro::Storable::freeze.
12 - major new feature: added Coro::Debug, for interactive coroutine 127 - major new feature: added Coro::Debug, for interactive coroutine
13 debugging, tracing and much more. 128 debugging, tracing and much more.
129 - major bug fix: unbelievable, but true: $_, $/ and many other
130 "saved" variables actually weren't being saved. This has been fixed,
131 of course, while increasing performance while losing all the save
132 flags.
133 - save flags are gone, and all the api functions dealing with them.
14 - added Coro::Semaphore::adjust. 134 - added Coro::Semaphore::adjust.
15 - added Coro::Util::fork_eval. 135 - added Coro::Util::fork_eval.
16 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}. 136 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
137 - added Coro::killall.
17 - reduce initial stack sizes to allow for "micro-coroutines". 138 - reduce initial stack sizes to allow for "micro-coroutines".
18 - better async_pool resource management, moved parts of async_pool 139 - better async_pool resource management, moved parts of async_pool
19 handling to XS (major speed improvement). 140 handling to XS (major speed improvement).
141 - actually croak before modifying important data structures.
142 - refuse to transfer while compiling.
143 - possibly support eval EXPR better now.
144 - enable assembly per default on linux+bsd x86+amd64.
145 - all internal members were renamed _something for easier subclassing.
20 - many minor tweaks. 146 - many minor tweaks.

223.63 Wed May 16 14:10:06 CEST 2007 1483.63 Wed May 16 14:10:06 CEST 2007
23 - implement handcoded assembly for x86/amd64 SVR ABI. 149 - implement handcoded assembly for x86/amd64 SVR ABI.
