- Serves as a first step for future refactors.
- Code is simpler.
- Algorithm is more efficient: instead of two passes (dumb copy + resolve copies), it's single-pass.
- Now obeys `PROPERTY_USAGE_NEVER_DUPLICATE`.
- Now handles deep self-references (the resource to be duplicated being referenced somewhere deep).
This was added together with `ppc64le` in #54490, but seemingly only for the
purpose of getting it to compile on a Linux distro that aims at maximizing
support for all CPU architectures.
I don't think anyone has ever _run_ Godot on a `ppc32` system (do those even
support OpenGL ES 3.0?) and so I don't think we should aim to support it.
Debian dropped support for its PowerPC (`ppc32`) arch in Debian 9, released
in 2017.
• Instead of calling to `_ref`, the same effect is achieved by calling to the base class assignment operator
• No longer need to be expose `_ref`; set back to private & remove reference from gdextension_interface
`variant_utility.cpp` has 8 different copies of the exact same loop to join
vararg strings together. This is bad coding process and makes the codebase
needlessly cluttered. Also, the loop itself has an i == 0 check that is
unnecessary since String is auto-initialized to be empty and String::operator+=
already checks if it is empty before appending. This is a non-functional change
that only reorganizes the code to be a bit more readable.
Removed calls to String::chr() when appending characters to Strings in Expression, Resource, and VariantParser, to avoid creating temporary Strings for each character. Also updated the Resource case to resize String up front, since size is known.
When we first integrated mbedTLS, we decided not to enable
MBEDTLS_THREADING_C (which adds mutex locking to calls modifying the
state), and instead to simply create separate contexts ("states") for
each connection.
This worked fine until recently.
Sadly, mbedTLS 3 added a global state for the new PSA crypto
functionalities (which are required to support TLSv1.3).
This results in TLSv1.3 connections to access and modify the global
state concurrently when running in threads.
This commit enables MBEDTLS_THREADING_C, and MBEDTLS_THREADING_C_ALT to
provide a generic Godot implementation using the engine Mutex class.
