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)
- Generalized pattern for substr in CheckStl::uselessCalls; added check for substr calls like ".substr(%any%,0)" which result in an empty string.

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.

Robert Reif 9a70ec87a8 convert CheckStl::if_find() to use the symbol database 2011-08-14 10:46:35 -04:00
Kimmo Varis 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.
