Fix #11904 (Scope::findFunction: better handling when non-virtual method with same name and arguments exists both in base class and derived class) (#5379) 2023-08-31 14:44:44 +02:00

report `internalError` when command execution returns errorcode / also some related cleanups and tests (#5037)
Encountered while investigating https://trac.cppcheck.net/ticket/11708.

This has been like this since the introduction of `internalError` in
b6bcdf2936 (almost ten years ago to the
day). Logging internal errors which bail out(!) of the analysis simply
to `std::cout` for them possibly never to be seen (and also not affected
the exitcode) is pretty bad IMO. They should always be visible.

I also removed the filename from the message as it is already available
(and thus redundant) and its existence should be defined by the
template.

sped up `Tokenizer::dump()` (#5009)
Scanning the `cli` folder with `DISABLE_VALUEFLOW=1` `Tokenizer::dump()`
will consume almost 25% of the total Ir count when an addon is
specified. This is mainly caused by the usage of `std::ostream`.

Encountered while profiling #4958.

Fix use-after-free crash when using --clang (#5367)
Still ran into an assert failure in `Tokenizer::hasIfdef()`, since some
checks assume that the tokenizer is always present. Seems like
clangimport is yet another rogue under-tested feature...

Oliver Stöneberg bfb50ca9d8
removed unnecessary `Settings` parameter from `Check::runChecks()` and made `Tokenizer` a reference (#5308)
There was no need for the `Tokenizer` parameter to be a pointer as it
could never be `nullptr` and was also dereferenced without checking
first.

As a reference to the `Settings` was already available via the
`Tokenizer` there was no need to pass it separately. In the production
code there will only be one instance of it but in the tests we could
have accidentally passed a different one.

fixed #6316 (Use std::to_string() in place of MathLib::toString() ...) - deleted default implementation of `Mathlib::toString()` (#5341)
It was also used inconsistently and seemed to imply there is some
special handling which wasn't the case. It was just an alias for
`std::to_string()` for non-`double` types. So there was no need for it.

pass `TokenList` as reference into `ValueFlow::setValues()` (#4868)
This avoid lots of unchecked pointer dereferences.

There was a single case which checked it and that looked like a
leftover. The only way this might have been a `nullptr` pointer was
through several default constructors which were not used at all so I
removed them.

Fix uninitvar false positive in designed initializers (#5079)
Stop interpreting struct fields in designed initializers as usage of local
variables which can happen if they share the same name.

```
$ cat test.c
struct a { int b; };
int main() {
  char *b;
  extern int foo(struct a *);
  return foo(&(struct a){.b = 0});
}
$ cppcheck --quiet test.c
test.c:5:27: error: Uninitialized variable: b [legacyUninitvar]
  return foo(&(struct a){.b = 0});
