WIP: restoring valgrind CI on smart_holder branch (#3090)
* * Rollback of PR #3068.
* Using latest pytest main branch for 3.9 and 3.10.
* WORKAROUND_ENABLING_ROLLBACK_OF_PR3068 in test_class_sh_trampoline_shared_from_this.py

First experiment combining two potential fixes: latest pytest, workaround.
If this succeeds the next step will be to try only latest pytest without the workaround.

Note: the workaround is known to resolve the MSAN error reported under
https://github.com/pybind/pybind11/pull/3068#issuecomment-877658470

* WORKAROUND_ENABLING_ROLLBACK_OF_PR3068 = False

* Narrowing down WORKAROUND_ENABLING_ROLLBACK_OF_PR3068 to Python 3.9

Ralf W. Grosse-Kunstleve 5af253d66c Adding test_multiple_registered_instances_for_same_pointee_recursive. 2021-06-30 07:04:31 -07:00
Ralf W. Grosse-Kunstleve a021e045a9 Adding test_multiple_registered_instances_for_same_pointee_leak. Subtle changes in smart_holder_type_caster_load, trying to work on weak_ptr for shared_ptr_trampoline_self_life_support, but that didn't work out. Manually fully leak-checked again. 2021-06-30 07:04:31 -07:00
Ralf W. Grosse-Kunstleve e2108546e1 Adding unit tests: 2 x test_std_make_shared_factory
Completes unit test coverage for the changed code in smart_holder_type_casters.h.

Ralf W. Grosse-Kunstleve 146a925e4e Resolving TODOs for `from_unique_ptr` `void_cast_raw_ptr`. Adding test to exercise the path through `cast`. The path through init.h is missing a test that would fail if the flag is incorrect. The plan is to systematically cover all situations (there are many that are not exercised for shared_from_this). 2021-06-30 07:04:31 -07:00
Ralf W. Grosse-Kunstleve a0e19bdc46 Use casting to `void *` to evade to shared_from_this mechanism only if `pointee_depends_on_holder_owner`, but currently only for `from_raw_ptr_take_ownership`. 2021-06-30 07:04:31 -07:00
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 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 3dd89f14df smart_holder_poc.h: type-erase raw_ptr before passing to shared_ptr::reset, to not trigger populating the shared_from_this weak_ptr. This way the only way the weak_ptr is populated is through loaded_as_shared_ptr. Breaks all but one test in test_class_sh_trampoline_shared_from_this.py, now marked skip WIP to test everything else with the GitHub CI. 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 4b872febcc Adding `test_pass_released_shared_ptr_as_unique_ptr`, exercising new guard in smart_holder_type_casters.h. 2021-06-30 07:04:31 -07:00
Ralf W. Grosse-Kunstleve e04196e82b Attempts to side-step various platform-specific issues. 2021-06-30 07:04:31 -07:00
Ralf W. Grosse-Kunstleve 553054b26b Adding tests involving stashing `shared_ptr`s. WIP. 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.
