- Added several types (std::) to isComplexType
- Types in namespace std:: are considered to have no side-effects (solved one TODO)
- Scope of a pointer can be limited without side effects
Refactorized usage of SymbolDatabase in checkOther:
- Don't copy Function instances in checkExpressionRange
- Simplifications by more accurate usage of information in database
- More accurate usage of symbolDatabase to reduce code and false negatives
- Avoided unnecessary construction of pattern string
- Only search for class/struct definition before usage
- Added support for pointers in self assignement check
- Removed redundant for loop in checknullpointer.cpp
- Fixed warning about signed/unsigned mismatch in cppcheck.cpp by making Settings::_maxConfig unsigned
- Print "inconclusive" tag in cli
- Fixed inconclusive handling in checkbufferoverrun.cpp
- Merged reportInconclusiveError into reportError by adding an additional parameter "bool inconclusive" which is false per default
- Added support for comparision of bool constant with number constant (-> fixed#1877) and integer variable with boolean expression
- Moved a check from checkComparisonOfBoolWithInt to checkComparisonOfBoolExpressionWithInt
- Generalized some patterns
- Made error message more accurate concnerning the "neither 0 nor 1" part.
- Reduced number of Token::Match calls
- Use more generic patterns
- Look on operator precedence more consequently
-> Made a TODO test case from a test case that worked previously, because the calculation is simplified so that the problem isn't detected any more.
Changed comment "Coding style checks" to "Checks", because it didn't fit
- Bailout on expanded macros for conclusive checking
- Support for more operators
- Removed indendation counter
Improved checkSignOfUnsignedVariable:
- Made the patterns more generic
- Improved verbose error message (-> Fixed#3080)
- Added a lot of additional pattern
- Rewrote error messages to make them more understandable and better fitting to the situation. (Fixed#3664)
- Cleanup in unit tests
Improved message of static string comparision check
Fixed false negative on argument count of fnprintf/snprintf when first variable argument is a string. (#3655)
Uncommented call of virtualDestructorError in getErrorMessages in checkclass.h
Refactorizations:
- Rearranged code in checkother.h to make ordering more consistent and to increase encapsulation of private data
- Replaced some single-token-patterns
Refactorizations in checkother.cpp:
- Make use of symboldabase instead of: indentation counters, manual detection of variable declarations
- Removed some indexing variables to reduce calls to tokAt and the numbers given to this function
- Use tok->nextArgument() to jump to a specific argument
Detect sign extension problems when variable is a reference (#3637)
Refactorizations:
- Tokenizer::getFiles returns a reference instead of a pointer, because its guaranteed that no nullpointer is returned
- Remove signed/unsigned in one step for "%type% signed|unsigned"
- Fixed recently introduced compiler warning in symboldatabase.cpp
-- Use MathLib::toLongNumber for conversion in tokenizer (Fix#3610)
-- Handle octal numbers in tokenizer
- Refactorizations in MathLib::toLongNumber and Settings
- Fixed false positive: throw outerCatchVar; in inner catch is now correctly handled
- Added eTry and eCatch to Scope::isLocal -> Scopes inside catch are now detected by symbol database
Add a check for function calls that have no side effects. That means
known const methods and a list including strcmp, strlen, etc.
If the function is not known to be side effect-free then no style
warning is given.
Add test cases for the duplicate expressions.
The code branch tested by the previous check for && is now different, so
I've changed the test to use == instead. There was also a missing case
when the expression was followed by a comma instead of being preceded by
one.
Expand the logic for the check for the same expression on both sides of
the || and && operators. Now expressions can be more complex, with the
"alt" variable helping to fudge operator precedence to avoid false
positives.
