Daniel Marjamäki b8d233f1a2 false poitive - invalid iterator after break 2012-04-09 07:19:39 +02:00
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.
 2012-04-04 19:44:57 +02:00
PKEuS bef2caf489 Improved checks in CheckStl: 
- Improved message of stlIfStrFind according to discussion on github (77d9ed1877)

Marek Zmysłowski 9a8c48b36e Fixed #3255 (Error message for std::string::c_str() is not descriptive) 2011-11-20 19:26:07 +01:00
Edoardo Prezioso 11dd3c09ce Change every 'tokAt(1)->' to 'next()->' because 'tokAt(1) == 0' is equivalent to 'next() == 0', hence the equivalent cppcheck crash. 2011-11-20 15:09:57 +01:00
Edoardo Prezioso 42e369a4b4 Change every 'tokAt(..)->link()' to 'linkAt(..)'. 2011-11-20 14:24:27 +01:00
Edoardo Prezioso 2c64d299ca Change every 'tokAt(...)->str()' to 'strAt(...)'. 2011-11-13 13:10:59 +01:00
Edoardo Prezioso b28a44dc3b Change: 'next()->next()'->'tokAt(2)', 'previous()->previous()'->'tokAt(-2)'. 2011-11-12 22:33:03 +01:00
Richard Quirk 7f88b66842 Fix namespaced types for auto_ptr new[] errors 
This fixes false negatives for code such as:

    std::auto_ptr<foo::bar> p(new foo::bar[10]);

The idea is to find a "new", search for the end token ";", then see if
the declaration ends in a closing square bracket. Also fixes other cases
that checked for "new %type% [" so that they work with namespaces.
 2011-11-06 21:20:24 +01:00
Richard Quirk 68202d8ffb Extra check for auto_ptr new[] 
This fixes cases like this:

   auto_ptr<foo> bar(new foo[10]);

which previously did not work correctly.

    return ("ERROR: " + msg).c_str();

or

    return ("ERROR: " + std::string("crash me")).c_str();
