IOBYTE ec8bc785a2 template simplifier: add support for using namespace when instantiating templates (#1615) 2019-01-23 08:53:01 +01:00
Paul Fultz II 3975913637 Extend lifetime checking for references
This will use the lifetime checker for dangling references. It will find these cases for indirectly assigned reference:

```cpp
int &foo()
{
    int s = 0;
    int& x = s;
    return x;
}
```

This will also fix issue 510 as well:

```cpp
int &f( int k )
{
    static int &r = k;
    return r;
}
```

Paul Fultz II 4b37f276c2 ValueFlow: Set arrays to true when converting to a boolean
This sets it by checking the parent. It doesn't handle function parameters yet.

library.cpp: Let tinyxml2 print a helpful error message when XML is bad (#1609)
In case the XML code of a library configuration is invalid Cppcheck now additionally prints out some helpful error description like this:
"Error=XML_ERROR_MISMATCHED_ELEMENT ErrorID=16 (0x10) Line number=304: XMLElement name=noreturn"

Lauri Nurmi 3bbd9fc9a4 Replace "virtual method" with "virtual function" in messages.
The term "method" is not really a part of C++ terminology.

One 'd' was missing.

Robert Reif 6ef8dad459 template simplifier: improve namespace matching
* out of line member functions are a namespace
* template<...> and *_cast<> can't be instantiations
* refactor code to use less function parameters
* fix instantiation scopes
* use full name with namespace when available
* fallback to just matching names when full name doesn't match

juremenart 45def06d59 fix trailing / from CMAKE JSON file and update unittests to cover both (w and w/o cases) (#1592)
* fix for CMake compile_commands.json input - director does not include trailing / which makes include directories wrong - so add it if it doesnt exist

* fix the bugfix for trailing / in the directory name of CMAKE JSON file, add also new test case to see if it works in both cases (with and without trailing /)

* revert adding accidental new line

		i = 1;

		i = 1;

ivangalkin 5ddc6c64d7 CheckStl: add missing error ID iterators2 (#1576)
due to equal arguments...

  * iterators1 (`CheckStl::iteratorsError(const Token*, const std::string&, const std::string&)`) and
  * iterators2 (`CheckStl::iteratorsError(const Token*, const Token*, const std::string&, const std::string&)`)

... produced equal messages. Equal messages were filtered-out `CppCheck::reportErr(const ErrorLogger::ErrorMessage&)`.
So the error iterators2 disapeared from the error list.

	bool b = (3 == 3); // <-- 1
	return a || b; // <-- 1
