Daniel Marjamäki fa94312c9a temporarily disable the 'object destroyed immediately' message 2010-10-03 16:59:13 +02:00
Pete Johns 78795dc3ac Fix false positive: Misused Scope Object does not pick constructors of local class declarations.
It does pick up if there is an unused construction within the function, though.
2010-10-02 22:59:04 +10:00
Pete Johns 365b1bed1a Fixed false positive: checkMisusedScopedObject no longer errors on calls to function objects. 2010-10-02 21:25:16 +10:00
Pete Johns b72b699b76 Fixed false-positive: Object is referenced on construction
struct Foo {
        void bar() {
        }
    };

    void fn() {
        Foo().bar(); // This caused a false-positive
    }
2010-10-02 20:26:29 +10:00
Pete Johns 3f72d3a877 Check misused scope object does not pick local class method.
Also fixed mistyped withinFuntion ->withinFunction.
2010-10-02 20:12:52 +10:00
Pete Johns 0017655f55 Added test for functor false-positive [passing]
Also removed typedef's following danmar's review and renamed isClassresults -> isClassResults to make more clear.
2010-10-02 18:45:24 +10:00
Pete Johns 6e0ef3eda2 Fixed #1132 (Detection of misused scope objects in functions)
Emits error in the form:

    [useless_lock.cpp:18]: (error) instance of "Lock" object destroyed immediately

    ...if an instance of a class or struct is unnamed and therefore destroyed
    straight after creation.

    Only checks for misused scope objects within functions.

    Optimised isIdentifierObjectType() by memoizing.

Pete Johns c6acdccfa0 Fixed #1132 (Detection of misused scope objects)
Emits error in the form:

    [useless_lock.cpp:18]: (error) instance of "Lock" object destroyed immediately

...if an instance of a class or struct is unnamed and therefore destroyed
straight after creation.

Removed "internal error" from token.cpp, since in this case varid would be NULL.

Daniel Marjamäki f843678a07 Redundant conditions: some refactorings
* removed the 'redundant null pointer' check. sometimes it's unsafe to delete NULL pointer. and this check doesn't point out errors anyway.
 * moved the 'redundant condition' check for set::remove. Moved it to CheckStl.
