PKEuS 0d316af4f2 Fixed false positive stlSize for code like "foo + 1 > bar.size()" (#4584) 2013-02-16 02:50:25 -08:00
Daniel Marjamäki 452dc23742 Fixed #4480 (False positive : Inefficient usage of string::find) 2013-02-14 19:14:20 +01:00
Daniel Marjamäki 08ada4cc63 Fixed #2652 (container .size() check too strict) 2013-02-14 16:59:58 +01:00
Andrew C. Martin bd0d9b9639 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:

 - 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
   - fc42fc95 fixes this particular runtime issue for DJGPP & __sun

PKEuS 45bad7d1b2 Refactorized tokenizer:
- Don't run setVarId() twice, keep old varId's while/after simplifyTokenList
-> Modified two test cases in testmemleak.cpp. I consider this to be safe. Feel free to investigate this.

PKEuS d6cfbc6483 Improved checks in CheckStl:
- Generalized check for inefficient emptiness check to detect !%var%.size() calls also outside of if and while; detect it also for %var%.size() when linked with && or ||.
Refactorizations in CheckStl:
- Removed an indendation counter and an offset variable
- Reduced distance given to tokAt calls in CheckStl::redundantCondition
- Rearranged code in CheckStl::missingComparison to use more efficient comparision of varIds instead of variable names. Use varId in pattern instead of variable name.
