Daniel Marjamäki 8a6a999f09 Fixed #2979 (Improve message: using char as array index) 2011-08-08 19:35:11 +02:00
Kimmo Varis cfcfa3f000 Use "enabled" list for the style checking.
Settings-class currently enables style checking via dedicated
boolean attribute. All other CLI's enable-options are handled
through the enable-list. This commit moves style-check enabling
to use the enable-list.

Main advantage is the consistency how options are handled/stored
in the Settings class. Which also unifies using them for the other
code. You need to enable certain type of checks? Use the
addEnabled()-method. You want to check if certain type of checks
are enabled? Use the isEnabled()-method.

It does pick up if there is an unused construction within the function, though.
2010-10-02 22:59:04 +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.
2010-10-02 14:22:26 +10:00
Pete Johns 50c2fa9ab0 Revert "Fixed #1132 (Detection of misused scope objects)"

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
