Add check for return value of boolean function ( #1451 )
...
* Add check for return value of boolean function
The rule for converting an integer to a boolean is that 0 is mapped to
false and everything else is mapped to true. There is nothing wrong with
the following code (according to the standards):
bool f()
{
return -1;
}
and neither gcc nor clang will warn about it. However, it's a bit
confusing. This commit adds a check that warns when a value other than 0
or 1 is returned from a boolean function (similar to the existing check
that functions with boolean arguments are only passed 0 or 1). Since the
code is perfectly legal, set the severity to "Style".
* Use early continue and remove some braces
* Add testcase with multiple returns
* Avoid null pointer dereference in case of return without operand
* Skip lambdas

Add a check that address of a single character is not passed as argument
to argument marked as strings (using strz). The check does not warn if
the address of a character with known value '\0'.
Since ValueFlow currently does not handle global constants (see #7597 ),
do not warn if the variable is global to avoid FPs when the address of
a global variable assigned to '\0' is passed to a function expecting a
string.
Remove comment in docs saying strz is unused.

Fixed #8693 (Template specialization: Constructor detected as normal … ( #1418 )
...
* Fixed #8693 (Template specialization: Constructor detected as normal function (functionStatic error))
Refactor template simplifier to remove the existing full specialization
function expandSpecialized and allow full specializations to use the
existing function expandTemplate. The function expandTemplate was
modified to either expand the template like it originally did by copying
it or to modify the template in place. Both instantiated and
uninstantiated full specializations are modified in place. This also
fixes #8692 and probably other related tickets as well.
The function simplifyTemplates now tries twice to simplify templates so
more templates can be simplified. We should try as many times as
necessary to find all possible templates. We can't do that now because
uninstantiated templates are left unchanged. It is relatively straight
forward to have the new code also expand in place uninstantiated
templates with their symbolic types but namespaces are not handled
properly (ticket #8671 ) and it would introduce regressions.
* Fix travis warnings.

The while part of a do-while loop looks almost like a function call, so

disabled for c++-code. Therefore, make sure the test cases are run on a
c-file.

isVariableDeclaration: Handle pointer to const pointer ( #1395 )

isVariableDeclaration did not handle pointer to const pointer, or
pointer to volatile pointer. This resulted in FPs in examples like the
following:
class Fred {
public:
const char *const *data;
const char *const *getData() { return data; };
}
where cppcheck would say getData could be static, since it didn't
recognize const char *const *data as a variable declaration.

Support floats in valid config ( #1297 )
...
* Add tests for invalid ranges
* Refactor loadLibErrors
This reduces the amount of code slightly and will simplify adding
more tests.
* Handle empty valid field
Before this change, the sequence <valid></valid> in a config file would
result in a segmentation fault. Now an empty field results in the error
message:
cppcheck: Failed to load library configuration file 'mycfg.cfg'. Bad attribute value '""'
* Add support for valid for floating point arguments
Previously, it was not possible to add valid ranges to floating point
arguments since it only handled integers. This made ranges not work well
for floating point arguments since arguments were cast to integers
before the ranges were handled.
Fix this by using doubles instead of integers if the argument is a float.
Add some tests for this and make sure errors are printed with enough
precision (somewhat arbitrarily chosen).
Note that it is still only possible to add integer ranges (i.e. -1:1).
* Add support for floats in configuration valid range
Now that it is possible to handle decimal arguments, there is no reason
to not allow non-integer ranges. Take care to not allow broken
configurations.
* Move check to within if-clause
* Move asin{,f,l} and acos{,f,l} input checks to config file

Fix crash bug #8579 ( #1238 )
...
* Added declaration for deletePrevious function
* Added definition for deletePrevious function
* Fixed crash from deleteThis invalidating pointers
The crash was caused by deleteThis() invalidating the pointer to a constant variable usage. This happened when a usage followed an assignment. This fixes bug #8579 .
* Added tokensFront to match tokensBack
This means deletePrevious can set the list's front if necessary.
* Initialised tokensFront in appropriate places
* Switched to using default Token constructor
* Switched to using Token default constructor
* Switched to using default constructor for Token
* Added missing argument to Token constructor

* Switched to using default constructor for Tokens

* Added new test for deleting front Token

* Syntax error
* Replaced tokensFront and tokensBack with a struct

* Replaced tokensFront and tokensBack with a struct

* Removed unnecessary scope operator
* Added missing parentheses
* Fixed syntax error
* Removed unnecessary constructor
* Default constructor now 0-initialises everything
This is safer for not using a temporary TokensFrontBack object, and doesn't use delegating constructors which aren't supported yet.
* Fixed unsafe null check
* Added missing explicit keyword
* Fixing stylistic nits
Removed default constructor as it has been superseded by the single-argument constructor with a default argument value.
Renamed listEnds to tokensFrontBack.
Fixed if statement that was supposed to be adding safety but would actually cause a crash if tokensFrontBack was null.
* Fixing stylistic nits
Removed default constructor and replaced it with a single-argument constructor with a default value.

std.cfg: Fix minsize configuration for vsprintf ( #1188 )
...
minsize with argvalue for arg 2 which is a char pointer makes no sense.
Changing it to minsize with strlen for arg 2 results in false positives
(and i think false negatives too).
In std.c a test with a valid vsprintf usage is added that would result
in a FP when minsize with strlen for arg 2 would be used.
