D:\vcpkg\toolsrc\include\catch2\catch.hpp(11288): warning C6330: 'char' passed as _Param_(1) when 'unsigned char' is required in call to 'isspace'.
ISO/IEC 9899:2011:
"7.4 Character handling <ctype.h>"/1
[...] In all cases the argument is an int, the value of which shall be
representable as an unsigned char or shall equal the value of the macro
EOF. If the argument has any other value, the behavior is undefined.
This means if isspace was passed a character like ñ it could corrupt
memory without the static_cast to treat it as a positive value after
integral promotion (and C libraries commonly use the int index supplied
as a key into a table which result in out of bounds access if the
resulting int is negative).
- Overrides added
- usages of push_back() replaced with emplace_back()
- Loop variable made const-refernce
- NULL replaced with nullptr
- Names used in the declaration and definition unified
- size() replaced with empty
- Identical cases merged
This way it is explicit when there is a `StringRef` -> `std::string`
conversion and makes it easier to look for allocations that could
be avoided.
Doing this has already removed one allocation per registered test
case, as there was a completely pointless `StringRef` -> `std::string`
conversion when parsing tags of a test case.
This adds UNSCOPED_INFO macro, creating a log message that is stored
until the end of next assertion or the end of test case, whichever comes
first. These messages are not scoped locally, unlike messages created by
INFO macro.
The previous implemetation was just plain broken for most of
possible uses, the new one should work (even though it is ugly
as all hell, and should be improved ASAP).
Fixes#1436
Because the macro name is compile-time constant, we do not have to
worry about lifetimes and will avoid allocation in case of missing
SSO or long macro name.
