The Abseil-NoInternalDependenciesCheck currently mistakenly triggers on any usage of internal helpers even if it is within absl/status.
Differential Revision: https://reviews.llvm.org/D85843
Summary:
This enables sharing the logic between standalone clangd and embedders
of it. The new approach should be same performance-wise, as it is only called
once per addDocument call.
This patch also introduces a blacklisting code path for disabling crashy or
high-noise tests, until we figure out a way to make them work with clangd-setup.
The biggest difference is the way we make use of preambles, hence those checks
can't see directives coming from the preamble section of the file. The second
thing is the fact that code might-not be compiling while clangd is trying to
build an AST, hence some checks might choke on those incomplete ASTs.

Summary:
Some clang-tidy checkers, e.g. llvm-include-order can emit diagnostics
at this callback (as mentioned in the comments).
Clangd was resetting diag consumer to IgnoreDiags before sending EOF, hence we
were unable to emit diagnostics for such checkers.
This patch changes the order of that reset and preprocosser event to make sure
we emit that diag.
Fixes https://github.com/clangd/clangd/issues/314.

I've dropped the background context parameter, since we in practice just pass the
current context there, and we now have a different way to specify context too.
While here, clean up a couple of comments.

This reverts commit 4061d9e42c.
Tests are failing in some configuration, likely due to not cleaning up
module cache path before running the test.

This lets basic AST-consuming actions be defined outside clangdserver.
(it essentially exposes TUScheduler::runWithAST).
Two use cases for now:
- replace ClangdServer::dumpAST, which doesn't really belong in the public
interface (a followup patch will do this)
- allow embedders to add/experiment with extra features
(e.g. I know some who want to try crazy AST+ML code completion...)
Maybe in the future we should use this sort of mechanism to make ClangdServer
less of a monolith, but that's not in scope for now.
This would probably require a richer and more carefully-thought-out API.

Skeleton checks generated by clang-tidy add_check.py cause assertions to fail when run over anonymous functions(lambda functions). This patch introduces an additional check to verify that the target function is not anonymous before calling getName().
The code snippet from the [[ https://clang.llvm.org/extra/clang-tidy/Contributing.html | clang-tidy tutorial ]]is also updated.

Currently, changes to includes are applied to an entire rule. However,
include changes may be specific to particular edits within a rule (for example,
they may apply to one file but not another). Also, include changes may need to
carry metadata, just like other changes. So, we make include changes first-class
edits.

When running dexp in remote mode without --project-root it shuts down
with an assertion. This is not the desired behaviour: instruct user on
how to run it properly when the configuration is incorrect.
Summary:
When preamble contains #undef, indexing code finds the matching #define
and uses that during indexing. However, it would only look for local
definitions. If the macro was defined in a module, MacroInfo
would be nullptr and clangd would crash.
This change makes clangd ignore any #undef without a matching #define
inside the same TU.
The indexing of macros happens for preamble only, so then #undef must be
in the preamble, which is why we need two .h files in a test.
Note that clangd is currently not ready for module support, but this
brings us one step closer.

This fixes a crash bug in clangd when used with modules. ASTWriter would
end up writing references to submodules into the PCH file, but upon
reading the submodules would not exists and
HeaderFileInfoTrait::ReadData would crash.

This checker appears to be intentionally not diagnosing cases where an
operator appearing in a duplicated expression might have side-effects;
Clang is now modeling fold-expressions as having an unresolved operator
name within them, so they now trip up this check.
Inside clangd, clang-tidy checks don't see preprocessor events in the preamble.
This leads to `Token::PtrData == nullptr` for tokens that the macro is defined to.
E.g. `#define SIGTERM 15`:
- Token::Kind == tok::numeric_constant (Token::isLiteral() == true)
- Token::UintData == 2
- Token::PtrData == nullptr
As the result of this, bugprone-bad-signal-to-kill-thread check crashes at null-dereference inside clangd.

`OS << ND->getDeclName();` is equivalent to `OS << ND->getNameAsString();`
without the extra temporary string.
This is not quite a NFC since two uses of `getNameAsString` in a
diagnostic are replaced, which results in the named entity being
quoted with additional "'"s (ie: 'var' instead of var).
