2 2
3TODO: better (earlier) error messages on broken transfer's 3TODO: should explore PerlIO::via::CoroCede and PerlIO::via::CoroAIO.
4TODO: destroy gets only called on cancel: fix(?) 4TODO: maybe implement a default message channel, very much like Erlang
5 (which is cool in a lot of important aspects (failures!),
6 but very lacking in others (higher level ipc)).
5 7
63.52 8 - do no longer rely on the presence of EV::DNS if EV is used
9 (because it is gone), but instead take avdantage of EV::ADNS
10 if available.
11 - add ($) prototypes to all functions in Coro::Storable.
12
134.22 Fri Nov 30 16:04:04 CET 2007
14 - really use optimised versions for Event and EV in Coro::Util
15 and Coro::Handle.
16
174.21 Sun Nov 25 10:48:59 CET 2007
18 - fix a spurious memory read.
19 - Coro::EV no longer keeps the eventloop "alive".
20
214.2 Fri Nov 9 20:47:05 CET 2007
22 - enable/disable tracing from a new coroutine, not a pooled one.
23 - fix a memleak in Coro::Event.
24 - removed killall call from fork_eval.
25 - made sure store_fd is already loaded so that fork_eval
26 does not have to parse autoload in each subprocess.
27 - only use assembly method if -O switch is in $Config{optimize}.
28 - add (optional) Coro::EV module, so far the best event loop module
29 directly supported by Coro.
30 - if the event model is EV, use EV::DNS to resolve
31 stuff in Coro::Util.
32 - don't get confused by multiple event notifications in Coro::Handle.
33 - initial support for EV (libevent interface).
34 - require Event and EV using configure_requires, to force their existance.
35
364.13 Wed Oct 24 07:26:45 CEST 2007
37 - add Coro::Storable::blocking_thaw.
38 - use a vastly more complicated technique to localise
39 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
40 - use a coroutine for the idle callback Coro::Event,
41 instead of running Event in the current coroutine context.
42 This also catches recursive invocations.
43 - actually report fork errors in gethostbyname and inet_aton.
44
454.11 Thu Oct 11 02:40:24 CEST 2007
46 - port to threaded perls.
47
484.1 Thu Oct 11 02:38:16 CEST 2007
49 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
50 be local to each coro (see Coro::State).
51 - incompatible change: for very deep reasons, cede and cede_notself
52 cannot return anything, so nothing will be returned.
53 - possibly bring back 5.10 compatibility (untested).
54 - work around stupid (and wrong) warning on 5.10 :(.
55 - overlay the saved state over the context stack. This saves
56 a few hundred bytes per coroutine on average and also
57 speeds up context switching a bit.
58 - further tune default stack sizes.
59 - (more) correctly calculate stack usage in coro_rss.
60 - Coro::Storable::blocking_* did not properly lock
61 resulting in races between coroutines.
62 - added Coro::Storable::guard.
63 - stopping to trace a coroutine could destroy the cctx of
64 an unrelated coroutine.
65 - explain the relationship between Perl and C coroutines in
66 more detail in Coro::State.
67 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
68 causing a fork per resolve. This also affected Coro::Socket.
69 - switch to a separate stack in $coro->call/eval to avoid
70 invalidating pointers.
71
724.03 Sat Oct 6 21:24:00 CEST 2007
73 - added Coro::throw method.
74 - minor code cleanups.
75
764.02 Sat Oct 6 02:36:47 CEST 2007
77 - fix a very minor per-coroutine memleak (a single codereference).
78 - fixed a bug where the currently in-use c context would be freed
79 prematurely (can happen only when programs change the stacksize
80 or use tracing).
81 - tracing can no longer keep a coro alive after it terminated.
82 - do static branch prediction in the common path for gcc. gives
83 about 2-5% speed improvement here.
84
854.01 Fri Oct 5 22:10:49 CEST 2007
86 - instead of recreating *a* standard output handle we simply
87 use STDOUT, which is faster and hopefully more robust.
88
894.0 Fri Oct 5 12:56:00 CEST 2007
90 - incompatibly changed Coro::Storable::freeze.
91 - major new feature: added Coro::Debug, for interactive coroutine
92 debugging, tracing and much more.
93 - major bug fix: unbelievable, but true: $_, $/ and many other
94 "saved" variables actually weren't being saved. This has been fixed,
95 of course, while increasing performance while losing all the save
96 flags.
97 - save flags are gone, and all the api functions dealing with them.
98 - added Coro::Semaphore::adjust.
99 - added Coro::Util::fork_eval.
100 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
101 - added Coro::killall.
102 - reduce initial stack sizes to allow for "micro-coroutines".
103 - better async_pool resource management, moved parts of async_pool
104 handling to XS (major speed improvement).
105 - actually croak before modifying important data structures.
106 - refuse to transfer while compiling.
107 - possibly support eval EXPR better now.
108 - enable assembly per default on linux+bsd x86+amd64.
109 - all internal members were renamed _something for easier subclassing.
110 - many minor tweaks.
111
1123.63 Wed May 16 14:10:06 CEST 2007
113 - implement handcoded assembly for x86/amd64 SVR ABI.
114
1153.62 Fri Apr 27 21:36:06 CEST 2007
116 - upgrade libcoro (which might set unwind info correctly).
117 - change default on linux to setjmp/longjmp.
118
1193.61 Thu Apr 19 12:36:18 CEST 2007
120 - Coro::Storable caused an endless loop when thawing invalid
121 pst's sometimes.
122 - use a Semaphore in Coro::Storable, as Storable doesn't
123 seem to be reentrant (although it is documented to
124 be threadsafe...).
125 - fix Coro::Signal to bring back the original unreliable
126 but stateful semantics.
127 - fixed a lot of typos in Coro.pm (patch submitted by David
128 Steinbrunner, which applied flawlessly).
129
1303.6 Sat Apr 14 17:13:31 CEST 2007
131 - added some bugfixes to get eg/myhttpd working again.
132 - added Coro::Storable for often-cede'ing freeze/thaw.
133 - try to do a clean exit when a coroutine calls exit
134 (EXPERIMENTAL).
135 - got rid of indirect call through _coro_init.
136 - updated the partly antique examples in eg/ to
137 work again and be a bit less magic, too.
138 - fixed Coro::Signal semantics to work as documented again.
139
1403.55 Sun Mar 25 01:20:47 CET 2007
141 - add SAVE_DEFFH to save the default filehandle and enable
142 it by default.
143 - finally move socket-operations from Coro::Socket to Coro::Handle
144 to be able to unblock foreign sockets.
145 - add Coro::State::save_also and guarded_save.
7 - add count accessor to Coro::Semaphore. 146 - add count accessor to Coro::Semaphore.
8 - add Coro::State::cctx_stacksize. 147 - add Coro::State::cctx_stacksize.
9 - just for the fun of it, do not rely on implicit context, 148 - just for the fun of it, do not rely on implicit context,
10 which can dramatically improve performance, but people 149 which can dramatically improve performance, but people
11 using windows-process-emulation perls do not care much about 150 using windows-process-emulation perls do not care much about
12 performance. 151 performance.
13 - finally move socket-operations from Coro::Socket to Coro::Handle
14 to be able to unblock foreign sockets.
