FMT_USE_STRING_VIEW define was incorrectly not being defined when using
modules, so there was no appropriate formatter specialization for
std::string_view
Fixes#4379
That way one can provide ones own implementation for assert_fail, which
is moved out of the detail namespace. For binary compatibility the
detail version stays to call the outer version.
* Handle allocator propagation in basic_memory_buffer::move
Update `basic_memory_buffer::move` to respect `propagate_on_container_move_assignment`allocator trait.
If the allocator should not propagate and differs from the target's allocator,
fallback to copying the buffer instead of transferring ownership.
This avoids potential allocator mismatch issues and ensures exception safety.
* Add test cases for the updated move ctor
- Added two test cases `move_ctor_inline_buffer_non_propagating` and `move_ctor_dynamic_buffer_non_propagating`
- Added `PropageteOnMove` template parameter to `allocator_ref` class to be compatible with the old test cases
- `allocator_ref` now implements `!=` and `==` operators
`<cstdlib>` was not being included, so malloc and free were only declared
via transitive includes. Some includes changed in the latest libc++-21
build which broke fmt.
Also changed `malloc`/`free` to `std::malloc` and `std::free`, as
putting those symbols in the global namespace is optional for the
implementation when including `<cstdlib>`.
* fix: avoid an implicit cast
The "1" used for the bitshift is treated as int, and this causes an
implicit conversion to `UInt` when performing the logical and.
Explicitly casting the number to `UInt` avoids the warning.
* fix: avoid implicit conversions for indices
Some indices in `include/fmt/base.h` are expressed as `int` types, which
causes an implicit conversion to a `size_t` when they are actually used
as index. Explicitly casting the value avoids the warning.
* fix: avoid an implicit conversion using size_t
The number of bits is used to express the size of a buffer. Using an
`int` causes an implicit conversion warning, let's use a `size_t` which
is the right type for the job.
