arrays: new ref counting and weak views
- improve the mem_block and shared_block. - the reference counting is now done in the mem_block and shared_block, removing the need of shared_ptr. - speed tests shows that shared_ptr is very slow (due to thread safety?) the new version is much better, though not perfect. - Hence introducing weak views. - also : -- clean the guard mechanism for python (to allow returning from python without any python ref left). -- clean code, add documentation for mem_block -- remove nan init, which was not working, and corresponding test -- serialisation of view still unchanged (need to forbid serialization of view ??). - tests ok, incl. valgrind tests.

/**
|

|
* This is a block of memory (pointer p and size size_).
|
||||||
|
* INTERNAL USE only, by shared_block only
|
||||||
|
*
|
||||||
|
* The memory can be :
|
||||||
|
*
|
||||||
|
* - allocated (and deleted in C++)
|
||||||
|
* - owned by a numpy python object (py_numpy)
|
||||||
|
*
|
||||||
|
* The block contains its own reference system, to avoid the use of shared_ptr in shared_block
|
||||||
|
* (which was very slow in critical codes).
|
||||||
|
*
|
||||||
|
* In addition, the python guard system can return to python an array allocated in C++.
|
||||||
|
*
|
||||||
|
* The memory block has 4 possible states (and only 4) :
|
||||||
|
*
|
||||||
|
* * State 0) : p ==nullptr && py_numpy == nullptr && py_guard == nullptr
|
||||||
|
* Default state. Also obtained when the object has been moved from
|
||||||
|
*
|
||||||
|
* * State 1) : p !=nullptr && py_numpy == nullptr && py_guard == nullptr
|
||||||
|
* Memory block allocated and used in C++.
|
||||||
|
*
|
||||||
|
* * State 2) : p !=nullptr && py_numpy != nullptr && py_guard == nullptr
|
||||||
|
* Memory block was allocated by python, and is used in C++.
|
||||||
|
* The block keeps a python ref (owned!) in py_numpy which is released at destruction
|
||||||
|
*
|
||||||
|
* * State 3) : p !=nullptr && py_numpy == nullptr && py_guard != nullptr
|
||||||
|
* Memory block allocated by C++, but passed to python.
|
||||||
|
* The guard is an owned reference to a python object, which itself owns a c++ reference to the mem_block
|
||||||
|
* When the python is done with this object, it releases this reference and the mem_block
|
||||||
|
* can be destroyed (when nobody else uses it).
|
||||||
|
* This guarantees that :
|
||||||
|
* * as long as python does not clean the guard (which is then later attached to a numpy array, cf numpy interface)
|
||||||
|
* the block will not be deleted.
|
||||||
|
* * when python is done with this numpy, hence the guard, the c++ reference is dec_refed and
|
||||||
|
* the usage can continue normally in c++ (without *any* python ref contrary to a previous design).
|
||||||
|
*
|
||||||
|
* * Invariants :
|
||||||
|
* * py_numpy == nullptr || py_guard == nullptr :
|
||||||
|
* * ref_count >=1.
