TODO:
Somehow Cppcheck fails to print an ignoredReturnValue message when the
return value is not used (see ticket
https://trac.cppcheck.net/ticket/9369 )
* Fix memleak FP with return with parenthesis
Fix FPs pointed out by daca@home on the following form:
void* f(void) {
void* x = malloc(1);
return(x);
}
Fix it by only skipping tokens if there is an actual match with a
variable. This allows to remove the special casing of "return;".
* Add testcase with cast
The file token-matching.xml contains multiple rules
- Add <rules></rules> xml tags
- Fixes the following xmllint error:
./rules/token-matching.xml:10: parser error :
Extra content at the end of the document
<rule version="1">
^
This fixes crashes found by daca where valueType() is NULL. Also,
somewhat related, it removes warnings when casting to a type that is
unknown to cppcheck, for example, there is no longer a warning for the
following code:
void* f() {
void *x = malloc(1);
return (mytype)x;
}
* Fix false negatives in checkAssignBoolToFloat
Detect assignments to expressions involving pointer dereferences, array
element accesses, etc.
* Pass assignment token to assignBoolToFloatError
Pass assignment token rather than boolean token to make error reporting
consistent between checkAssignBoolToFloat and checkAssignBoolToPointer,
as well as with other assignment checks in the code base.
* Make checkAssignBoolToPointer check consistent with checkAssignBoolToFloat
This was most likely introduced when the checks were changed to run on
the full tokenlist instead of the simplified one.
Take care to warn about cases where casts destroy the pointer, such as
uint8_t f() {
void* x = malloc(1);
return (uint8_t)x;
}
* Add impossible category
* Replace values
* Try to adjust known values
* Add ! for impossible values
* Add impossible with possible values
* Remove contradictions
* Add values when the branch is not dead
* Only copy possible values
* Dont bail on while loops
* Load std lib in valueflow
* Check for function calls
* Fix stl errors
* Fix incorrect impossible check
* Fix heap-after-use error
* Remove impossible values when they are lowered
* Show the bound and remove overlaps
* Infer conditions
* Dont push pointer values through dynamic_cast
* Add test for dynamic_cast issue
* Add shifttoomanybits test
* Add test for div by zero
* Add a test for issue 9315
* Dont make impossible value inconclusive
* Fix FP with shift operator
* Improve handleKnownValuesInLoop for impossible values
* Fix cppcheck warning
* Fix impossible values for ctu
* Bailout for streams
* Check equality conditions
* Fix overflows
* Add regression test for 9332
* Remove duplicate conditions
* Skip impossible values for invalid value
* Check for null
* Rename bound to range
* Formatting
Python 3 does not search parent directories of the initially executed
script for modules imported by modules in this parent directory by
default. So simply set the PYTHONPATH to the ./addons directory. Thus
all scripts are found. It is similar to running the test-*.py script
from the ./addons directory, but this way all the paths in the test-*.py
scripts do not have to be changed (for example to find the cppcheck
executable.
For more details regarding the parent directory issue see for example:
