Fix false positive introduced by
0b7649ca9b
Only return the function token from checkTokenInsideExpression when it
might be one the argument (hence keeping a pointer to one of them).
Otherwise, we can directly skip to the token after the function call.
* Fix 9298
Tell cppcheck that strcpy returns its first argument, and use that
knowledge in checkTokenInsideExpression.
* Add missing unit tests in cmake
* cppcheck.cpp: Check for JSON error when parsing addon .json files
This fixes that errors in JSON files given via `--addon=*.json` are
silently ignored and maybe only a part of the JSON file is used.
Now the error message which picojson can return is checked and a
corresponding error message is returned again by getAddonInfo().
* naming.json: Fix missing comma
* CLI: Fix naming violations detected by addon naming.py via naming.json
* Addon naming: Add argument for validating names of constants
* LIB: Rename functions/variables so they are valid, loosen naming rules
* GUI: Fix naming violations
* 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
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;
}
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;
}
* Fix FP memory leak with unknown function call in condition
This was introduced in 8513fb81d2 when
fixing memory leaks for global variables allocated in condition. The
refactored code had an inconsistency where c and c++ code behaved
slightly differently when `var` is NULL. This seemed to not have an
impact as the code was written prior to 8513fb81d2,
but when the same code was used for conditions, FPs were introduced.
The introduced FPs were memleak warnings when there should have been an
information message about missing configurations for code like
void f() {
char *p = malloc(10);
if (set_data(p)) {}
}
Fix this by always returning true if varTok->Variable() is NULL for
both c and c++ code.
* Improve function name
* Fix#9097 (Crash on thousands of "else ifs"s in gcc-avr package)
* increase recursion count maximum to 512 because cppcheck was hitting the 256 limit
* 512 was too much for windows
* Allow to configure realloc like functions
* memleakonrealloc: Bring back tests.
The old memleak checker was removed, and the tests for it was removed in
commit 9765a2dfab. This also removed the
tests for memleakOnRealloc. Bring back those tests, somewhat modified
since the checker no longer checks for memory leaks.
* Add realloc to mem leak check
* Add tests of realloc buffer size
* Configure realloc functions
* Add test of freopen
* Allow to configure which element is realloc argument
* Fix wrong close in test
cppcheck now warns for this
* Update manual
* Update docs
* Rename alloc/dalloc/realloc functions
Naming the member function realloc caused problems on appveyor. Rename
the alloc and dealloc functions as well for consistency.
* Change comparisson order
* Remove variable and use function call directly
* Create temporary variable to simplify
* Throw mismatchError on mismatching allocation/reallocation
* Refactor to separate function
* Fix potential nullptr dereference
As pointed out by cppcheck.
* Fix#9047 (c-style casts before malloc)
Note that there are still no warnings for c++-style casts
* Fix memleak check with casts of assignments in if-statements
* Fix possible null pointer dereference
As pointed out by cppcheck.
* Add check of astOperand2 when removing casts
This is similar to how it is done in other checks.
