PKEuS ec1bd420a7 Refactorizations optimizing std::string usage:
1) Added global static const std::string emptyString; object:
-> Replaces some static variables in functions which might be not threadsafe
-> Avoids constructor call (std::string::string(""))
-> Even functions that return an empty string in some branches can return by reference now.
Added to config.h to ensure that it is available everywhere

2) Added overloads for TestFixture::assertEquals for the most common use cases:
-> Moves conversion from const char[] to std::string into a function, reducing code duplication in binary.

Daniel Marjamäki a4a6f3e1be Tokenizer: Removed Tokenizer::simplifyConditionOperator(). Using the AST and ValueFlow, it should be much easier to parse ?: than before. 2014-06-10 19:30:13 +02:00

Andrew C. Martin 4a73c93750 Fix compiler warnings and comment/string typos
- fix g++ warning:

> lib/checkother.cpp:3779: warning: comparison between signed and unsigned integer expressions

 - fix suncc warning (see [everything2](http://everything2.com/title/C%252B%252B%253A+static+extern+%2522C%2522)):

> "lib/checkmemoryleak.cpp", line 578: Warning (Anachronism): Formal argument __compar of type extern "C" int(*)(const void*,const void*) in call to bsearch(const void*, const void*, unsigned long, unsigned long, extern "C" int(*)(const void*,const void*)) is being passed int(*)(const void*,const void*).

- prefer empty() / isEmpty() over "size() > 0" (cases not caught by stlSize)

- fix word misspellings (mostly comments, a few output lines)

  - Parenthesis => Parentheses (both variations were used in the codebase)

  - fix typo and wording ("never alwayw") in gui/test/data/benchmark/simple.cpp's CheckOther::unsignedPositive():

```
-  "An unsigned variable will never alwayw be positive so it is either pointless or "
+  "An unsigned variable can't be negative so it is either pointless or "
```

Applied "patch" provided by michaeln123 in #4071
2012-08-22 17:28:06 +02:00
PKEuS 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

PKEuS c8e40773f1 Fixed cppcheck messagesa about functions that can be const/static:
- Made Tokenizer::getErrorMessages static - Avoids creation of unnecessary instance of Tokenizer
- Changed Tokenizer::removeExceptionSpecifications to common style for simplification functions. In contrast to the comment, this function doesn't call itself recursivly - fixed comment.
- Made Tokenizer::IsScopeNoReturn static.
2012-08-01 12:04:47 -07:00
PKEuS e9182f1fcc Implemented support for 'using namespace std;': Add std:: prefix to names that are known to be in std namespace. Simplify namespace (std::)tr1:: if C++11 flag is set. 2012-07-15 02:05:19 -07:00

PKEuS 4b80e91145 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)

Edoardo Prezioso 52620e6493 Tokenizer::simplifyDoWhileAddBraces:
1)rewrite fix for ticket #988 (just don't simplify inside macro parenthesis);
2)use a different organization of the code: start from last token and proceed backwards. This way 'simplifyDoWhileAddBracesHelper' can be called just once, hence the 'Helper' code can be improved and moved in the main function.
