Haojian Wu ee08036df8 [clangd] Deduplicate clang-tidy diagnostic messages.
Summary:
Clang-tidy checks may emit duplicated messages (clang-tidy tool
deduplicate them in its custom diagnostic consumer), and we may show
multiple duplicated diagnostics in the UI, which is really bad.

This patch makes clangd do the deduplication, and revert the change
rL363889.

Sam McCall d98170c324 [clangd] Use shorter, more recognizable codes for diagnostics.
Summary:
 - for warnings, use the flag the warning is controlled by (-Wfoo)
 - for errors, keep using the internal name (there's nothing better) but
   drop the err_ prefix

This comes at the cost of uniformity, it's no longer totally obvious
exactly what the code field contains. But the -Wname flags are so much
more useful to end-users than the internal warn_foo that this seems worth it.

This enables clangd to intercept compiler diagnostics and attach fixes (e.g. by
querying index). This patch adds missing includes for incomplete types e.g.
member access into class with only forward declaration. This would allow adding
missing includes for user-typed symbol names that are missing declarations
(e.g. typos) in the future.

Chandler Carruth 2946cd7010 Update the file headers across all of the LLVM projects in the monorepo
to reflect the new license.

We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.

Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

Sam McCall 991e316126 [clangd] Replay preamble #includes to clang-tidy checks.
Summary:
This is needed to correctly handle checks that use IncludeInserter,
which is very common.

I couldn't find a totally safe example of a check to enable for testing,
I picked modernize-deprecated-headers which some will probably hate.
We should get configuration working...

This depends on D54691 which ensures our calls to getFile(open=false)
don't break subsequent accesses via the FileManager.

After this, it's easy to serialize diagnostics using the structured

Sam McCall c008af6466 [clangd] Namespace style cleanup in cpp files. NFC.
Standardize on the most common namespace setup in our *.cpp files:
  using namespace llvm;
  namespace clang {
  namespace clangd {
  void foo(StringRef) { ... }
And remove redundant llvm:: qualifiers. (Except for cases like
make_unique where this causes problems with std:: and ADL).

This choice is pretty arbitrary, but some broad consistency is nice.
This is going to conflict with everything. Sorry :-/

Squash the other configurations:

A)
  using namespace llvm;
  using namespace clang;
  using namespace clangd;
  void clangd::foo(StringRef);
This is in some of the older files. (It prevents accidentally defining a
new function instead of one in the header file, for what that's worth).

B)
  namespace clang {
  namespace clangd {
  void foo(llvm::StringRef) { ... }
This is fine, but in practice the using directive often gets added over time.

C)
  namespace clang {
  namespace clangd {
  using namespace llvm; // inside the namespace
This was pretty common, but is a bit misleading: name lookup preferrs
clang::clangd::foo > clang::foo > llvm:: foo (no matter where the using
directive is).

Sam McCall bed5885d9e [clangd] Upgrade logging facilities with levels and formatv.
Summary:
log() is split into four functions:
 - elog()/log()/vlog() have different severity levels, allowing filtering
 - dlog() is a lazy macro which uses LLVM_DEBUG - it logs to the logger, but
   conditionally based on -debug-only flag and is omitted in release builds

All logging functions use formatv-style format strings now, e.g:
  log("Could not resolve URI {0}: {1}", URI, Result.takeError());

Existing log sites have been split between elog/log/vlog by best guess.

This includes a workaround for passing Error to formatv that can be
simplified when D49170 or similar lands.
