c537a86363 Fixed false negative in unused variable checking when class without side effects inherits from another one. 2012-08-20 07:55:39 -07:00

35d94c26d5 Changed creation of SymbolDatabase. Database always created after Tokenizer::tokenize() and Tokenizer::simplifyTokenList() instead of on-demand creation by Tokenizer::getSymbolDatabase. 
-> With Token::scope() it is possible to access the symboldatabase without having to call getSymbolDatabase(). The change increases safety because it is guaranteed that the database is available in all checks, even if the specific check doesn't call getSymbolDatabase
- Tokenizer::_symbolDatabase does no longer have to be mutable -> Increased const correctness

The change above required two additional changes:
- A bug causing a debug message was fixed in the symboldatabase that became visible in the test suite by the change above.
- Simplify expressions like "struct struct Foo" which might be result of typedef instanciation.

355c1322d6 Small refactorizations in checkunusedvar.cpp: 
- Token::Match handles nullpointers
- In chained assignments variables are only written (not read) when assigned
- Fixed crash #4033

d5f6cfcfa8 Tokenizer: Use new setVarId function. Removed the old one. 2012-04-22 11:36:31 +02:00
Daniel Marjamäki
aeac38b673 Tokenizer::setVarIdNew: Removed test case in TestUnusedVar that fails with the new setVarId function. The new setVarId function assumes that 'static int i(a);' is a variable declaration if it's in a executable scope (it is unknown if 'a' is a type or a variable so this assumption could be wrong). 2012-04-22 10:42:55 +02:00

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.
