Refactorizations on buffer overrun check:
...
- Replaced a few indendation counters by smaller and faster code
- Make use of safer nextArgument() function instead of some local implementations
- Replaced some simple patterns by direct function calls
- Made a strncpy/strncat search pattern more generic
- Replaced offset variable by incrementation of Token* to avoid subsequent calls to tokAt
- Increased data encapsulation in header

Added check for invalid pointer casts ( #1255 )
...
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
2012-02-26 11:56:32 +01:00

Add InternalError and change MathLib to throw it in case of an error.
...
- Previously MathLib errors did not provide a filename, but after this change at least source file name should be printed
and if token is provided, also line number should be printed.
- Change also Token to use InternalError
- Modify Cppcheck-class to catch InternalError instead of Token
- Run dmake to update Makefile

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.
