Ralf W. Grosse-Kunstleve ccd16a1a14 Adding test_pure_cpp_sft_raw_ptr (with 3 TODO: Fix), test_pure_cpp_sft_shd_ptr (works as desired). 2021-06-30 07:04:31 -07:00
Ralf W. Grosse-Kunstleve 10abe15052 Automatic clang-tidy fixes. 2021-06-30 07:04:31 -07:00
Ralf W. Grosse-Kunstleve 48eb78ae77 Simpler and safe implementation based on new requirement: C++ (outside of the Python object) needs to hold a shared_ptr before shared_from_this is called. This is more similar to the existing implementation on current smart_holder HEAD, but still uses a weak_ptr to always return the same shared_ptr as long as C++ does not let it expire. 2021-06-30 07:04:31 -07:00

Ralf W. Grosse-Kunstleve adfd3e1700 Partial cleanup of tests. WIP. The cleanup uncovered a major problem. 2021-06-30 07:04:31 -07:00
Ralf W. Grosse-Kunstleve bfd4c4893e Leveraging new `noop_deleter_acting_as_weak_ptr_owner` to retrieve released `vptr`. 
The placeholder `vptr` is never exposed anymore, therefore the externally visible `use_count`s are more intuitive.

Ralf W. Grosse-Kunstleve 4218213f29 nodiscard fix. 2021-06-30 07:04:31 -07:00
Ralf W. Grosse-Kunstleve bf8d6a2900 First fully successful attempt to make `shared_from_this` and trampolines play nicely. 
Now also passes the open_spiel iterated_prisoners_dilemma_test ASAN clean, in addition to all pybind11 and PyCLIF unit tests.

The problem was that calling `std::shared_ptr<void>::reset()` with a `void` pointer cannot possibly update the `shared_from_this` `weak_ptr`.

The solution is to store a `shd_ptr_reset` function pointer in `guarded_deleter` (similar in idea to the stored function pointer for calling `delete`).

This commit still includes all debugging code, i.e. is "dirty". The code will be cleaned up after the GitHub CI is fully successful.
