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
- removed unused function CheckOther::concatNames
- Replaced one indendation counter by Token::link() in checkother.cpp
- Forward declaration of Settings in threadexecutor.h
- 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
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
- 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.
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.
This checks for the case where the user thought sizeof(buf) gave the
size in bytes of 'buf' in code like the following:
const char *buf = "Hello World";
strncmp(buf, other, sizeof(buf));
The symbol database is unavailable during token simplification
and &data[0] might return something completely different for C++.
Moved code_is_c() from checkOther to Tokenizer.
statements if they are followed by a {..} block.
Examples are:
for (int i = 0; i < 10; ++i);
{
printf("i)";
}
or
if (i == 100);
{
die("Wrong argument");
}
This new check is active if you enable inconclusive checks.
