411c9158ed A signal used as a slot should throw an expired_slot exception, 
instead of a bad_weak_ptr.

087da776e9 Added support for tracking signal objects. Moved signal_base out 
of detail namespace, since it is used as an argument in a public
method now.  Fixed track_test.cpp to use new signal tracking
method.

e7382cd7c0 Removed overload of slot::track() that takes a signal reference, 
since signals cannot be tracked in general (except in the usual way
all other objects can be tracked.


[SVN r3764]
 2007-03-05 21:08:38 +00:00
Frank Mori Hess
5c96f547cd Added shared_connection_block::block() to allow user to

011fdb87b5 Throw more specific "expired_slot" exception, derived from bad_weak_ptr 
when slot is called with an expired tracked object.


[SVN r3760]
 2007-03-05 15:10:55 +00:00

0ac91083af Restored explicit slot-to-slot tracking, since implicit version 
only detects slot expiration on invocation.


[SVN r3759]
 2007-03-05 14:52:46 +00:00
Frank Mori Hess
84dd05468f Made slots throw bad_weak_ptr when called with expired tracked 
objects.  Combiners now have to catch bad_weak_ptr exceptions
thrown on slot iterator dereference.  Tracking works automatically
now for slots that call other slots.

61a18d5ac0 Got rid of signalslib::connection::block() and unblock() and replaced 
them with exception-safe signalslib::shared_connection_block() class.
The new way is also more useable in a multi-threaded context, since
it prevents one thread from unexpectedly unblocking a
connection that another thread wants blocked.

b0be180326 Tweaked constant-time garbage collection to clean up long contiguous 
blocks of dangling connections in one pass.

3acddc8716 Fixed some problems with slot ordering due to my misunderstanding 
of how std::map::insert() handles the case of an already existing
key.


[SVN r3752]

Frank Mori Hess
66f76f5839 Restored per-slot locking, due to unresolvable failures in deletion_test.cpp. 
Restored ThreadingModel parameter due to popular demand, but made default
"signals::auto_threaded" which uses the lightweight_mutex.  Removed
obsolete trackable.hpp.


[SVN r3751]
 2007-03-01 15:57:25 +00:00
Frank Mori Hess
3d2cd4ca2a Got rid of per-slot mutexes and ThreadingModel template parameter. 
Use boost/detail/lightweight_mutex.hpp for the mutex now.  Still
need to optimize locking so it doesn't lock the mutex once for
every slot during invocation.


[SVN r3749]
 2007-02-28 20:48:30 +00:00
Frank Mori Hess
fcb6e2e506 Fixed signal::disconnect() with a slot function argument, which 
was broken by recent changes to slot class.

[SVN r3742]
 2007-02-28 16:19:41 +00:00
Frank Mori Hess
bef2bfc4fb Added some templated copy constructors to slot class, to prevent 
loss of tracking on copy construction.


[SVN r3741]
 2007-02-28 15:54:22 +00:00
Frank Mori Hess
a7d581107b Added Signature template parameter to slot class, so that an 
operator() could be added.  Bind can be used to bind together
slots with different signatures now.  Added some syntactic
sugar to slot constructors, so a bind() call is inserted automatically
for the constructors that take more than one argument.
All tracking for automatic connection
management is now done through slot::track().
Added track_test.cpp test program, which tests some of the new
functionality.

54c4fe3f19 Handle reference-wrapped values gracefully for the sake of the 
2 parameter version of track().

6d1e6bdc0f tracked object returned by single argument track() should at least 
support conversion back into a shared_ptr.


[SVN r3732]
 2007-02-22 19:51:20 +00:00
Frank Mori Hess
ca88cf698c Forget about trying to support implicit conversions for the sake of 
easy binding.  The user can use the two argument form of track if
they need to.


[SVN r3731]
 2007-02-22 18:54:58 +00:00
Frank Mori Hess
0153eec102 Added support for 2-argument form of signalslib::track(), which allows 
value and shared_ptr to be specified independantly.


[SVN r3730]
 2007-02-22 16:57:12 +00:00

e3fbf95743 Made add_tracked() a public member of the slot class, so arbitrary 
objects can be added for the purpose of automatic connection management.


[SVN r3728]

for equality after one was copy constructed or assigned from the other.

d698187147 Don't need to call lockNextCallable() in constructor at all (thanks 
Timmo).


[SVN r3708]

Frank Mori Hess
7143a7f202 Reduced number of shared_pointers that have to be 
created during invocation by one.  Made lock_memory_pool a little more
likely to catch misuse.  Moved some lockNextCallable() calls into
slot_iterator constructor.

I think I've found all the straight-forward optimizations now.

Frank Mori Hess
1784478549 Added support for turning on and off thread safety through 
ThreadingModel template parameter.  For thread-safe signals,
the file thread_safe_signals/multi_threaded.hpp must be
included in addition to the main header file.


[SVN r3703]
 2007-02-17 03:12:22 +00:00
Frank Mori Hess
31e3582021 Got rid of stupid quick_ptr optimization attempt, as the lack of 
thread-safety on destruction is lethal.

 2007-02-16 21:35:09 +00:00
Frank Mori Hess
1f6057171c Performance optimization: use scoped_ptr instead of shared_ptr to hold 
lock in slot_call_iterator.  Reduces per-slot invocation overhead
by about 50%.

82dc145f4e A slot can now disconnect it self without deadlock. 
I reduced lock contention.  Now, disconnect()
can complete while the signal is being
invoked (though not while the slot in question
is actively running in any
other thread).  The signal may be invoked concurrently, but any
particular slot will not be run concurrently.  connect() may complete
while the signal is being invoked.
