Auto-generated patch based on clang-tidy readability-identifier-naming.
Only some manual cleanup for `extern "C"` declarations and a GTest change was required.
I'm not sure if this cleanup is actually very useful. It cleans up clang-tidy findings to the number of warnings from clang-tidy should be lower. Since it was easy to do and required only little cleanup I thought I'd upload it for discussion.
One pattern that keeps recurring: Test **matchers** are also supposed to start with a lowercase letter as per LLVM convention. However GTest naming convention for matchers start with upper case. I would propose to keep stay consistent with the GTest convention there. However that would imply a lot of `//NOLINT` throughout these files.
To re-product this patch run:
```
run-clang-tidy -checks="-*,readability-identifier-naming" -fix -format ./clang-tools-extra/clangd
```
To convert the macro names, I was using this script with some manual cleanup afterwards:

Without this patch the file list of the preamble index contains URIs, but other indexes file lists contain file paths.
This makes `indexedFiles()` always returns `IndexContents::None` for the preamble index, because current implementation expects file paths inside the file list of the index.
This patch fixes this problem and also helps to avoid a lot of URI to path conversions during indexes merge.

Current indexes merge logic skip data from the static index if the file is in the dynamic index, but sometimes the dynamic index does not contain references (e.g. preamble (dynamic) index vs background (static) index).
This problem is masked with the fact, that the preamble index file list consists of file URI's and other indexes file lists consist of file paths.
This patch introduces the index contents (symbols, references, etc.), which makes indexes merge more flexible and makes it able to use URI's for the index file list.

Summary:
This is another step for out-of-order preamble builds. To keep the
diagnostic behavior same, we only build ASTs either with "usable" preambles,
the ones that are fully applicable to a given ParseInput, or after building a
new preamble. Which is the same behaviour as what we do today. ASTs
built in the latter is called golden ASTs.

Summary:
This ties to an LSP feature (diagnostic versioning) but really a lot
of the value is in being able to log what's happening with file versions
and queues more descriptively and clearly.
As such it's fairly invasive, for a logging patch :-\
Key decisions:
- at the LSP layer, we don't reqire the client to provide versions (LSP
makes it mandatory but we never enforced it). If not provided,
versions start at 0 and increment. DraftStore handles this.
- don't propagate magically using contexts, but rather manually:
addDocument -> ParseInputs -> (ParsedAST, Preamble, various callbacks)
Context-propagation would hide the versions from ClangdServer, which
would make producing good log messages hard
- within ClangdServer, treat versions as opaque and unordered.
std::string is a convenient type for this, and allows richer versions
for embedders. They're "mandatory" but "null" is a reasonable default.

This is how it should've been and brings it more in line with
std::string_view. There should be no functional change here.
This is mostly mechanical from a custom clang-tidy check, with a lot of
manual fixups. It uncovers a lot of minor inefficiencies.
This doesn't actually modify StringRef yet, I'll do that in a follow-up.
Summary:
The historic behavior of TestTU is to gather diagnostics and otherwise ignore
them. So if a test has a syntax error, and doesn't assert diagnostics, it
silently misbehaves.
This can be annoying when developing tests, as evidenced by various tests
gaining "assert no diagnostics" where that's not really the point of the test.
This patch aims to make that default behavior. For the first error
(not warning), TestTU will call ADD_FAILURE().
This can be suppressed with a comment containing "error-ok". For now that will
suppress any errors in the TU. We can make this stricter later -verify style.
(-verify itself is hard to reuse because of DiagnosticConsumer interfaces...)
A magic-comment was chosen over a TestTU option because of table-driven tests.
In addition to the behavior change, this patch:
- adds //error-ok where we're knowingly testing invalid code
(e.g. for diagnostics, crash-resilience, or token-level tests)
- fixes a bunch of errors in the checked-in tests, mostly trivial (missing ;)
- removes a bunch of now-redundant instances of "assert no diagnostics"

This much better reflects what is (now) in this header.
Maybe a rename to ParsedTU would be an improvement, but that's a much
more invasive change and life is too short.
ClangdUnit is dead, long live ClangdUnitTests!
llvm-svn: 370862
Summary:
Those errors are exposed at the first character of a file,
for a lack of a better place.
Previously, all errors were stored inside the AST and report
accordingly. However, errors in command-line argument parsing could
result in failure to produce the AST, so we need an alternative ways to
report those errors.
We take the following approach in this patch:
- buildCompilerInvocation() now requires an explicit DiagnosticConsumer.
- TUScheduler and TestTU now collect the diagnostics produced when
parsing command line arguments.
If pasing of the AST failed, diagnostics are reported via a new
ParsingCallbacks::onFailedAST method.
If parsing of the AST succeeded, any errors produced during
command-line parsing are stored alongside the AST inside the
ParsedAST instance and reported as previously by calling the
ParsingCallbacks::onMainAST method;
- The client code that uses ClangdServer's DiagnosticConsumer
does not need to change, it will receive new diagnostics in the
onDiagnosticsReady() callback
Errors produced when parsing command-line arguments are collected using
the same StoreDiags class that is used to collect all other errors. They
are recognized by their location being invalid. IIUC, the location is
invalid as there is no source manager at this point, it is created at a
later stage.
Although technically we might also get diagnostics that mention the
command-line arguments FileID with after the source manager was created
(and they have valid source locations), we choose to not handle those
and they are dropped as not coming from the main file. AFAICT, those
diagnostics should always be notes, therefore it's safe to drop them
without loosing too much information.

Summary:
Previously, we randomly pick one main file symbol in dynamic index, we
may loose the ideal symbol (with definition location) in the index.
It fixes the issue where sometimes we fail to go to the symbol definition, see:
1. call go-to-decl on Foo in Foo.cpp
2. jump to Foo.h, call go-to-def on Foo in Foo.h
we can't go back to Foo.cpp -- because we open Foo.cpp, Foo.h in clangd, both
files have Foo symbol (one with def&decl, one with decl only), we randomely
choose one.

Summary:
For counting number of references clangd was relying on merging every
duplication of a symbol. Unfortunately this does not apply to FileIndex(and one
of its users' BackgroundIndex), since we get rid of duplication by simply
dropping symbols coming from non-canonical locations. So only one or two(coming
from canonical declaration header and defined source file, if exists)
replications of the same symbol reaches merging step.
This patch changes reference counting logic to rather count number of different
RefSlabs a given SymbolID exists.

Add an initial '::' qualifier to all usages of 'testing' namespace that
did not have one.
The goal is to make our code style in tests more consistent.
llvm-svn: 360026
Summary:
Motivation:
- this layout is a pain to work with
- without a common root, it's painful to express things like "disable clangd" (D61122)
- CMake/lit configs are a maintenance hazard, and the more the one-off hacks
for various tools are entangled, the more we see apathy and non-ownership.
This attempts to use the bare-minimum configuration needed (while still
supporting the difficult cases: windows, standalone clang build, dynamic libs).
In particular the lit.cfg.py and lit.site.cfg.py.in are merged into lit.cfg.in.
The logic in these files is now minimal.
(Much of clang-tools-extra's lit configs can probably be cleaned up by reusing
lit.llvm.llvm_config.use_clang(), and every llvm project does its own version of
LDPATH mangling. I haven't attempted to fix any of those).
Docs are still in clang-tools-extra/docs, I don't have any plans to touch those.
