C standards say that "char" may either be a "signed char" or "unsigned char" but that it is up to the compilers implementation or the platform which is followed. Some non x86 platforms, including PowerPC and ARM, treat unspecified chars as unsigned chars, so it is necessary to explicitly declare them as "signed char" (or to compile with "--signed_chars").
This fix ensures that fluid synth's sample's pitchadj value are correctly read as signed.
* The one C4100
* The one C4189
* The two C4457
* The two C4701
* The 475 C4267, changing to size_t were easily possible, casting to
int elsewhere
* Fix GCC warnings reg. wrong printf format for a size_t, reg. unused
variables and reg. ambigous else branch, seen on Travis CI
This commit contains changes required for MuseScore to compile under MSVC with no warnings.
MuseScore is being compiled with the /W4 setting (warning level 4), which is similar to -wall -wextra on clang. This generates lots of warnings on MSVC, mainly for non-standard constructs and for constructs which might be bugs or might lead to bugs.
Most warnings are in the following categories:
- Name hiding: a variable hides a variable with the same name on a larger scope (or a field, or a function parameter). This can easily lead to bugs, and it is a best practice to avoid hiding variable names (see recommendation ES.12 in the C++ Core Guidelines by Stroustrop & Sutter (http://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines#Res-reuse : ES.12: Do not reuse names in nested scopes)
- Narrowing conversion: a numeric conversion results in loss of significant digits (for example, double -> float). The general recommendation is to use a cast to indicate this is designed behaviour.
- Unreachable code: in several instances, there is unreachable code. The unreachable code is commented out.
- (Potentially) uninitialized local variable. Just initialized the vars.
- foreach(,) -> for(:): this does not generate a warning per-se (only a few of these generate warnings due to name hiding), but changed in keeping with "MuseScore Coding Rules" (https://musescore.org/en/handbook/musescore-coding-rules#Loops), which tells explicitly "Use C++11's "for" instead of Qt's "foreach":" ... "If you happen to be fixing some code and see a "foreach", please change that loop into a "for"."
Most changes are in the categories indicated above. The next listing shows detailed changes for files which are *not* of the aforementioned types.
