Implemented support for move constructors:
...
- Changed behaviour of Token::function - is now also set for declarations
- Resolved TODO in testclass.cpp
- removed redundant code in Scope::findFunction - it is safe to call nextArgument() on functions without arguments
- Use Token::function in checkother.cpp

- Current implementation sets Variable::isReference() to true also for rvalue references - they can probably be treated like normal references in many checks.
Changed behaviour of symbol database: Insert argument Variable of functions that are not implemented into SymbolDatabase::_variableList

Use global Settings instance in TestCmdlineParser, since most tests just need it to pass something to CmdlineParser class.

fix misspellings & gcc v3.4.6 warnings
...
1. fix typos / misspellings
- Fix misspelling within comments, variable/function names, stdout messages
- changes the name of an error code: ```stlBoundries``` changed to ```stlBoundaries```. Alias old name (```stlBoundries```) to the new one.
2. fix gcc v3.4.6 32bit & 64bit warnings
- fixes gcc v3.4.6 warnings, except for those in tinyxml and "-Wmissing-declarations" makefile warnings
- in Preprocessor::handleIncludes(), replace a ```vector <bool>``` with ```stack<bool>``` (see ```vector<bool>``` warning below).
- this is the only ```vector<bool>``` in the codebase
- ```vector <bool>``` is actually a case of template specialization, and is not recommended, according to the following links:

http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2160.html
http://stackoverflow.com/q/670308
- in the codebase before and after this change, testrunner SEGVs in a number of places on gcc v3.4.6, including ```Check::~Check()```, among others

Properly implement %op% for Token::multiCompare

- Check for sizeof()*sizeof(): This indicates that programmer misunderstood what sizeof() does: It does return the length in bytes of the given variable, not e.g. the number of elements in an array.

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.
2012-08-12 03:01:24 -07:00

Implemented support for building cppcheck lib into a dll
...
Updated VS9 solution
New VS10 solution that builds cppcheck into a dll used by cli and testrunner.
Functional changes and advantages of new solution:
- Share code between testrunner and cli; ability to share code with gui as well (not yet implemented)
- Files of /lib are no longer compiled twice (should improve build time on single core machines)
- Added configuration for building with PCRE support
- Executables are build into /bin (/bin/debug in debug mode) folder (Should no longer require rebuild when switching between debug and release)
- Completely x64 compatible (contains also x64-debug configuration now)

Refactorizations in test suite:
...
- Implement createOnly mode in givenACodeSampleToTokenize so that only createTokens is called instead of tokenize
-> Ensures that no simplifications are done which could make the testing basic functions (like Token::Match) less accurate. We often don't need this simplifications in testtoken.cpp.
-> Ensures that no validation of the source is done (Fix #2104 )
- reduced overhead of givenACodeSampleToTokenize: Don't store a std::istringstream instance, avoid creation of std::string when ctor is called

Refactorizations in class Token: changed handling of different types of tokens.
...
- Replace _isNumber, _isName, _isBoolean attributes by a single _type attribute (enum Token::Type), because not two of the old booleans could be true at the same time.
-> Add support for lots of different other kinds of tokens. (More precise checking of token type possible)
-> Replaced instant checking of type for Operators, etc. by a value calculated at creation time. (Faster checking)
