Alexander Kornienko 02bd018aeb Disable most of the google-readability-casting check for non-C++ files (only
leave the "redundant cast to the same type" part).

Hans Wennborg dfd8c74a98 [clang-tidy] Don't leak the TodoCommentHandler object
Preprocessor:addCommentHandler() does not take ownership,
so we'd end up leaking the TodoCommentHandler.

This patch makes it owned by the Check object.

Benjamin Kramer 6be414da26 [clang-tidy] Add a checker that warns on TODO comments without username.
It also suggests a fix-it, taking the name from $USER. This will be made
configurable eventually.

Benjamin Kramer ae8fc52237 [clang-tidy] Don't emit the same fixit multiple times.
If we had many header files we would attach the fix-it for all files to all
warnings, oops. This is harmless 99.9% of the time but can confuse the rewriter
in some edge cases. Sadly I failed to create a small test case for this.

While there move fix-its instead of copying.

Benjamin Kramer eb213cb1cd [clang-tidy] When emitting header guard fixes bundle all fix-its into one
warning.

Before we would emit two warnings if the header guard was wrong and the comment
on a trailing #endif also needed fixing.

Benjamin Kramer 6e195426e7 [clang-tidy] Add a checker for long functions.
As this is very dependent on the code base it has some ways of configuration.
It's possible to pick between 3 modes of operation:

- Line counting: number of lines including whitespace and comments
- Statement counting: number of statements within compoundStmts.
- Branch counter

In addition a threshold can be picked, warnings are only emitted when it is met.
The thresholds can be configured via a .clang-tidy file.

Alexander Kornienko 6e0cbc8947 Implemented clang-tidy-check-specific options.
Summary:
Each check can implement readOptions and storeOptions methods to read
and store custom options. Each check's options are stored in a local namespace
to avoid name collisions and provide some sort of context to the user.

Ever wanted to fix all the header guards in clang? Now it's easy.

  $ svn diff

Some may argue that this is just a glorified xargs -P, but it does a bit more ;)

Benjamin Kramer 498cce575f [clang-tidy] Add a generic header guard checker + LLVM implementation.
The implementation is split into a generic part and a LLVM-specific part.
Other codebases can implement it with their own style. The specific features
supported are:

- Verification (and fixing) of header guards against a style based on the file path
- Automatic insertion of header guards for headers that are missing them
- A warning when the header guard doesn't enable our fancy header guard optimization
(e.g. when there's an include preceeding the guard)
- Automatic insertion of a comment with the guard name after #endif.

For the LLVM style we disable #endif comments for now, they're not very common
in the codebase. We also only flag headers in the include directories, there
doesn't seem to be a common style outside.

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.

Summary:
class Foo {
  Foo() {

  }
  Foo(int);
};

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.
