After https://reviews.llvm.org/D80531 landed, a subtle bug was introduced where the test would fail if `LLVM_ENABLE_WERROR` was set. This just silences that error so the test case runs correctly, down the line it may be worth not enabling `-Werror` for clang-tidy tests even if the cmake flag is passed.
Make check_clang_tidy.py not just pass -format-style=none by default
but a full -config={}. Without this, with a build dir outside of
the llvm root dir and a .clang-tidy config further up that contains
CheckOptions:
- key: modernize-use-default-member-init.UseAssignment
value: 1
these tests would fail:
Clang Tools :: clang-tidy/checkers/cppcoreguidelines-prefer-member-initializer-modernize-use-default-member-init.cpp
Clang Tools :: clang-tidy/checkers/modernize-use-default-member-init-bitfield.cpp
Clang Tools :: clang-tidy/checkers/modernize-use-default-member-init.cpp
After this change, they pass fine, despite the unrelated
.clang-tidy file further up.
With every incremental change, one needs to check-in new model upstream.
This also significantly increases the size of the git repo with every
new model.
Testing and comparing the old and previous model is also not possible as
we run only a single model at any point.
One solution is to have a "staging" decision forest which can be
injected into clangd without pushing it to upstream. Compare the
performance of the staging model with the live model. After a couple of
enhancements have been done to staging model, we can then replace the
live model upstream with the staging model. This reduces upstream churn
and also allows us to compare models with current baseline model.
This is done by having a callback in CodeCompleteOptions which is called
only when we want to use a decision forest ranking model. This allows us
to inject different completion model internally.

Previous attempt (15f6bad6d7) introduced

between RemoteIndexProto and RemoteIndexServiceProto. This is likely due
to some requirements of it that clang_add_library violates.
As a workaround, we will link RemoteIndexProto library to
RemoteIndexServiceProto which is logical because the library can not be

In `ReplayPreamble::replay`, use `getFileRef` instead of `getFile`, and
then use that `FileEntryRef` later to avoid needing
`FileEntryRef::FileEntryRef`. The latter is going to become private to
`FileManager` in a later commit.
We only need to version these messages if they actually diverge.
Unlike the service, the namespace name isn't part of the wire format.
clangd-index-server was broken by 81e5f298c4
as the namespace names weren't updated there, this fixes it (by adding
them for the service, and not requiring them elsewhere).
This allows it to have a separate namespace (grpc versioned service) without
putting versioning info on all of the other protos (before we need it).
clang-index-server is still broken (from 81e5f298c4).

The patch adjusts the existing `llvm::DenseMap<unsigned, T>` and
`llvm::DenseSet<unsigned>` objects that store source locations, so
that they use `SourceLocation` directly instead of `unsigned`.
This patch relies on the `DenseMapInfo` trait added in D89719.
It also replaces the construction of `SourceLocation` objects from
the constants -1 and -2 with calls to the trait's methods `getEmptyKey`
and `getTombstoneKey` where appropriate.

This change creates a `DenseMapInfo` trait specialization for the
SourceLocation class. The empty key, the tombstone key, and the hash
function are identical to `DenseMapInfo<unsigned>`, because we already
have hash maps that use raw the representation of `SourceLocation` as
a key.
The update of existing `DenseMap`s containing raw representation of
`SourceLocation`s will be done in a follow-up patch. As an example
the patch makes use of the new trait in one instance:

This reverts commit 1b589f4d4d and relands the D89463
with the fix: update `MappingTraits<FileFilter>::validate()` in ClangTidyOptions.cpp to
match the new signature (change the return type to "std::string" from "StringRef").
Original commit message:
This:
Changes the return type of MappingTraits<T>>::validate to std::string
instead of StringRef. It allows to create more complex error messages.
It introduces std::vector<std::pair<StringRef, bool>> getEntries():
a new virtual method of Section, which is the base class for all sections.
It returns names of special section specific keys (e.g. "Entries") and flags that says if them exist in a YAML.
The code in validate() uses this list of entries descriptions to generalize validation.
This approach was discussed in the D89039 thread.

This is done automatically in C++20 mode using `std::ranges::reverse_view` but there are options to specify a different function to reverse iterator over a container.
This is the first step, down the line I'd like to possibly extend this support for array based loops
```

Currently if you pass a reversing function with no header in the options it will just assume that the function exists, however as we have the ASTContext it may be as wise to check before applying, or at least lower the confidence level if we can't find it.

use. Later it could be renamed to `getBuffer`, but intentionally using
a different name to root out any unexpected callers.
- `ContentCache::getBufferPointer`, which returns `MemoryBuffer*` with
"optional" semantics. This is `private` to avoid growing callers and
`SourceManager` has temporarily been made a `friend` to access it.
Later paches will update the transitive callers to not need a raw
pointer, and eventually this will be deleted.

This patch introduces hoisting detection logic into prepare state with
a partial AST traversal of the enclosing function.
We had some complaints from the users about this code action being almost always
available but failing most of the time. Hopefully this should reduce that noise.
The latency/correctness tradeoff is a bunch of hand-waving, but at least today
we don't have any other actions that are available on selection of statements,
so when we get to do the traversal it is quite likely that all the other checks
will bail out early. But this is still up for discussion, I am happy to abandon
the patch if you believe this is not practical.
