Summary:
Suppose `clangd::` is unresolved in the following example. Currently,
we simply use "clangd::" as the query scope. We can do better by combining with
accessible scopes in the context. The query scopes can be `{clangd::, clang::clangd::}`.
```
namespace clang { clangd::^ }
```

Summary:
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.

ClangTidyOptions::getDefaults is not free, it will initialize all
clang-tidy modules to get check-specific options, and we don't use this
information in CodeComplete, so using an empty one (constructed by

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.

The new guideline is to qualify with 'llvm::' explicitly both in
'.h' and '.cpp' files. This simplifies moving the code between

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).

This patch moves the virtual file system form clang to llvm so it can be
used by more projects.
Concretely the patch:
- Moves VirtualFileSystem.{h|cpp} from clang/Basic to llvm/Support.
- Moves the corresponding unit test from clang to llvm.
- Moves the vfs namespace from clang::vfs to llvm::vfs.
- Formats the lines affected by this change, mostly this is the result of
the added llvm namespace.

llvm-svn: 343912
Summary:
The file stats can be reused when preamble is reused (e.g. code
completion). It's safe to assume that cached status is not outdated as we
assume preamble files to remain unchanged.
On real file system, this made code completion ~20% faster on a measured file
(with big preamble). The preamble build time doesn't change much.

Summary:
To stay fast, enable single-file-mode instead. This is fine since completions
in the preamble are simple.
The net effect for now is to suppress the spurious TopLevel completions when
completing inside the preamble.
Once Sema has include directive completion, this will be more important.

- DynamicIndex doesn't implement ParsingCallbacks, to make its role clearer.
ParsingCallbacks is a separate object owned by the receiving TUScheduler.
(I tried to get rid of the "index-like-object that doesn't implement index"

- Clarified(?) docs around DynamicIndex - fewer details up front, more details
inside.
- Exposed dynamic index from ClangdServer for memory monitoring and more
direct testing of its contents (actual tests not added here, wanted to get
this out for review)
- Removed a redundant and sligthly confusing filename param in a callback

Summary:
Currently, a symbol can have only one #include header attached, which
might not work well if the symbol can be imported via different #includes depending
on where it's used. This patch stores multiple #include headers (with # references)
for each symbol, so that CodeCompletion can decide which include to insert.
In this patch, code completion simply picks the most popular include as the default inserted header. We also return all possible includes and their edits in the `CodeCompletion` results.

Summary:
For index-based code completion, send an asynchronous speculative index
request, based on the index request for the last code completion on the same
file and the filter text typed before the cursor, before sema code completion
is invoked. This can reduce the code completion latency (by roughly latency of
sema code completion) if the speculative request is the same as the one
generated for the ongoing code completion from sema. As a sequence of code
completions often have the same scopes and proximity paths etc, this should be
effective for a number of code completions.

Moreover, the code path that attempts to get parameter comments never

that claims to fetch parameter comments: it is not used anymore and is
incorrect.
