Summary:
Rename ChecksFilter to GlobList, as there's nothing specific to checks in it.
It's a rather generic way to represent sets of strings (or patterns), so it may
be used for something else in ClangTidy. The new name would not look strange
when used to filter other entities.

Haven't thought that I ever needed to do this, but in this case comparing the
index using pointer arithmetic turns out to be really ugly. It also generates
nasty sign-compare warnings on 32 bit targets.

This allows us to copy the parameter name from the definition (as a comment)
or insert /*unused*/ in both places.

This is valid code but it does nothing and we can't emit a warning in clang
because there might be side effects. The checker emits a warning for this
pattern and also for base class initializers written in this style.
There is some overlap with the unused-rtti checker but they follow different
goals and fire in different places most of the time.

It doesn't make sense to suggest 'virtual' as clang-tidy would complain
about that on the next iteration (we are never issuing warnings for the
base function).

ASTMatchers currently have problems mixing bound TypeLoc nodes with Decl/Stmt
nodes. That should be fixed soon but for this checker there we only need the
TypeLoc to generate a fixit so postpone the potentially heavyweight AST walking
until after we know that we're going to emit a warning.
This is covered by existing test cases.
Original message:
[clang-tidy] Add a check for RAII temporaries.
This tries to find code similar that immediately destroys
an object that looks like it's trying to follow RAII.
{
scoped_lock(&global_mutex);
critical_section();
}
This checker will have false positives if someone uses this pattern
to legitimately invoke a destructor immediately (or the statement is
at the end of a scope anyway). To reduce the number we ignore this
pattern in macros (this is heavily used by gtest) and ignore objects
with no user-defined destructor.

This required a rather ugly workaround for a problem in ASTMatchers where
callee() is only overloaded for Stmt and Decl but not for Expr.

This reverts commit r213308.
Reverting to have some on-list discussion/confirmation about the ongoing
direction of smart pointer usage in the LLVM project.

If there's memset(x, y, 0) in the code it's most likely a mistake. The
checker suggests a fix-it to swap 'y' and '0'.
I think this has the potential to be promoted into a general clang warning
after some testing in clang-tidy.

Imagine, hypothetically, that you had a build of clang-tidy that enabled
the google-* checks by default. If you had such a binary, then this
test would fail. Making it pass in that configuration isn't such a bad
thing.
llvm-svn: 213085
Summary:
We still allow the escape hatch foo(int /*x*/) and also suggest this
in a fixit. This is more powerful than the corresponding cpplint.py check
it also flags functions with multiple arguments as naming all arguments is
recommended by the google style guide.

Those may be incompatible with C++11 and are unnecessary. We suggest
removing the template arguments when they match the types of the make_pair
arguments or replace it with std::pair and explicit template arguments when
not.

This looks for swapped arguments by looking at implicit conversions of arguments
void Foo(int, double);
Foo(1.0, 3); // Most likely a bug
llvm-svn: 212942
Summary:
This patch implements a subset of possible replacements of C-style
casts with const_cast/static_cast/reinterpret_cast. This should cover a large
portion of cases in real code. Handling of a few more cases may be implemented
eventually.

The goal is to find code like the example below, which is likely a typo
where someone meant to write "if (*b)".
bool *b = SomeFunction();
if (b) {
// b never dereferenced
}
This checker naturally has a relatively high false positive rate so it
applies some heuristics to avoid cases where the pointer is checked for
nullptr before being written.
