* override: Fix wrong caching of the overrides
There was a problem when the python type, which was stored in override
cache for C++ functions, was destroyed and the record wasn't removed from the
override cache. Therefor, dangling pointer was stored there. Then when the
memory was reused and new type was allocated at the given address and the
method with the same name (as previously stored in the cache) was actually
overridden in python, it would wrongly find it in the override cache for C++
functions and therefor override from python wouldn't be called.
The fix is to erase the type from the override cache when the type is destroyed.
* test: Pass by const ref instead of by value (clang-tidy)
* test: Rename classes and move to different files
Rename the classes and files so they're no too generic. Also, better place to
test the stuff is in test_virtual_functions.cpp/.py as we're basically testing
the virtual functions/trampolines.
* Add TODO for erasure code
* [pre-commit.ci] auto fixes from pre-commit.com hooks

* Fix compiler errors
* Use PY_VERSION_HEX for a cleaner CVE-2008-5983 mode check.
* Fix typo
* Use explicit type for deleter so delete[] works cross-compiler.
* Always use PySys_SetArgvEx because pybind11 doesn't support pythons that don't include it.
* Remove pointless ternary operator.
* Use unique_ptr.reset instead of a second initialization.
* Rename add_program_dir_to_path parameter to clarify intent.
* Add defined() check before evaluating HAVE_BROKEN_MBSTOWCS.

Catch v2 changed the `run(...)` signature to take a `char *argv[]`,
arguing partly that technically a `char *argv[]` type is the correct
`main()` signature rather than `const char *argv[]`.
Dropping the `const` here doesn't appear to cause any problems with
catch v1 (tested against both the cmake-downloaded 1.9.3 and Debian's
1.12.1 package) so we can follow suit.
* Fix segfault when reloading interpreter with external modules
When embedding the interpreter and loading external modules in that
embedded interpreter, the external module correctly shares its
internals_ptr with the one in the embedded interpreter. When the
interpreter is shut down, however, only the `internals_ptr` local to
the embedded code is actually reset to nullptr: the external module
remains set.
The result is that loading an external pybind11 module, letting the
interpreter go through a finalize/initialize, then attempting to use
something in the external module fails because this external module is
still trying to use the old (destroyed) internals. This causes
undefined behaviour (typically a segfault).
This commit fixes it by adding a level of indirection in the internals
path, converting the local internals variable to `internals **` instead
of `internals *`. With this change, we can detect a stale internals
pointer and reload the internals pointer (either from a capsule or by
creating a new internals instance).
(No issue number: this was reported on gitter by @henryiii and @aoloe).
In the latest MSVC in C++17 mode including Eigen causes warnings:
warning C4996: 'std::unary_negate<_Fn>': warning STL4008: std::not1(),
std::not2(), std::unary_negate, and std::binary_negate are deprecated in
C++17. They are superseded by std::not_fn(). You can define
_SILENCE_CXX17_NEGATORS_DEPRECATION_WARNING or
_SILENCE_ALL_CXX17_DEPRECATION_WARNINGS to acknowledge that you have
received this warning.
This disables 4996 for the Eigen includes.
Catch generates a similar warning for std::uncaught_exception, so
disable the warning there, too.
In both cases this is temporary; we can (and should) remove the warnings
disabling once new upstream versions of Eigen and Catch are available
that address the warning. (The Catch one, in particular, looks to be
fixed in upstream master, so will probably be fixed in the next (2.0.2)
release).
- For the debian/buster docker build (GCC 7/C++17) install and use the
system `catch` package; this also renames "COMPILER_PACKAGES" to
"EXTRA_PACKAGES" since it now contains a non-compiler package.
- Add a status message indicating the catch version being used for
compiling the embedded tests
- Simplify some bash code by using VAR+=" foo" to append (rather than
VAR="${VAR} foo"
- Fix CMAKE_INCLUDE_PATH appending: it was prepending the ':' but not
the existing $CMAKE_INCLUDE_PATH value and so would end up with
":/eigen-path" if CMAKE_INCLUDE_PATH was already set. (This wasn't
bug that was actually noticed since currently nothing else sets it).
Fixes a race condition when multiple threads try to acquire the GIL
before `detail::internals` have been initialized. `gil_scoped_release`
is now tasked with initializing `internals` (guaranteed single-threaded)
to ensure the safety of subsequent `acquire` calls from multiple threads.
Py_Finalize could potentially invoke code that calls `get_internals()`,
which could create a new internals object if one didn't exist.
`finalize_interpreter()` didn't catch this because it only used the
pre-finalize interpreter pointer status; if this happens, it results in
the internals pointer not being properly destroyed with the interpreter,
which leaks, and also causes a `get_internals()` under a future
interpreter to return an internals object that is wrong in various ways.
At this point, there is only a single test for interpreter basics.
Apart from embedding itself, having a C++ test framework will also
benefit the C++-side features by allowing them to be tested directly.
