Kimmo Varis 85187dca07 Update VS 2008/2010 project files for tests. 2011-02-03 17:53:50 +02:00
Kimmo Varis 2d6d8580d7 Allow to exclude filenames (with paths).
This expands the CLI exclude feature to also allow excluding
filenames (with paths). When filename with recognized extension
is given to -i option then matching filenames (with paths) are
ignored when checking.

Only match full directory names as parts of whole paths. So -isrc
matches src/file.cpp and proj/src/file.cpp. But does not match
mysrc/file.cpp or proj/srcfiles/file.cpp.

Kimmo Varis 6401271ceb Add CLI support for ignoring paths.
Add support for giving list of ignored paths from CLI. This way
user can define paths one doesn't want to check (like generated
code). This first simple implementation only does exact matching,
no support for wildcards etc. And matching is always agains dir
names.

If the filtered dir name is part of the checked filename then the
file is ignored.

Pete Johns 098f0bf3e6 Fixed #2526 (Make TODO_ASSERT_EQUALS take three arguments (value, to_be, as_is)?...
Removed replaced EXPECTED with...

WANTED (to-be):     The future expected value.
CURRENT (as-is):    Documenting how cppcheck behaves now.

This removes the need for an ASSERT_EQUALS but enforces the check for every TODO_ASSERT_EQUALS.

Kimmo Varis d334a02801 Make --exitcode-suppressions option consistent.
The --exitcode-suppressions option was inconsistent with other
long options by taking the filename as separate argument. Now
it expects format --exitcode-suppressions=filename.txt like
other long options.

Daniel Marjamäki ed6c76ce04 Fixed #2385 (False positive: array index out of bounds) 2010-12-31 17:43:38 +01:00
Pete Johns 502cfe7243 Fixed #2384 ("The function 's::f' can be const" reported for pointer-to-pointer)
Moved check for pointer variables into isVariableDeclaration()

Can now handle multiple scopes and multiple levels of indirection. Simplified check for strucs and unions, too, reducing the size of getVarList().

skipScopeIdentifiers() and skipPointers() should probably be methods on class Token.

symboldatabase now recognises variables with arbitrarily many scopes.

Extracted method isVariableDeclaration()

Added unit tests for isVariableDeclaration in new file testsymboldatabase.cpp

Extracted givenACodeSampleToTokenize helper class into testutils.h to reduce duplication.
