Summary:
It simply shows the completed/total items on the background queue, e.g.
indexing: 233/1000
The denominator is reset to zero every time the queue goes idle.
The protocol is fairly complicated here (requires creating a remote "progress"
resource before sending updates). We implement the full protocol, but I've added
an extension allowing it to be skipped to reduce the burden on clients - in
particular the lit test takes this shortcut.
The addition of background index progress to DiagnosticConsumer seems ridiculous
at first glance, but I believe that interface is trending in the direction of
"ClangdServer callbacks" anyway. It's due for a rename, but otherwise actually
fits.

This reverts commit 079ef783dd.
The revert describes a test failure without details, after offline
discussion this in in a private/unsupported build system and doesn't
seem to reflect a real upstream bug.
This reverts commit d6417f5584. The tests
depend on builtin headers, which is not intentionally supported in
clangd tests; these tests are broken in some build environments.
Summary:
This adds an implementation for the "textDocument/documentLink" LSP request.
It returns links for all `#include` directives to the resolved target files.
Fixes https://github.com/clangd/clangd/issues/217.

Summary:
This is mostly mechanical, with a few exceptions:
- getDeducedType moved into AST.h where it belongs. It now takes
ASTContext instead of ParsedAST, and avoids using the preprocessor.
- hover now uses SelectionTree directly rather than via
getDeclAtPosition helper
- hover on 'auto' used to find the decl that contained the 'auto' and
use that to set Kind and documentation for the hover result.
Now we use targetDecl() to find the decl matching the deduced type instead.
This changes tests, e.g. 'variable' -> class for auto on lambdas.
I think this is better, but the motivation was to avoid depending on
the internals of DeducedTypeVisitor. This functionality is removed
from the visitor.

Summary:
Adds Semantic Ranges capabilities to Clangd server.
Also adds tests for running it via clangd server.
This differs from the LSP spec as the spec needs this to be evaluated on multiple 'pos' and the expected output is an list of list of semantic ranges.
This is majorly for multi cursor and assuming this is a rare thing, we don't want to optimize make things complicated just for this.
This should be done in the LSP level by queueing one request per 'pos' in the input.

Summary:
Previously it was rebuilding every 5s by default, which was much too frequent
in the long run - the goal was to provide an early build. There were also some
bugs. There were also some bugs, and a dedicated thread was used in production
but not tested.
- rebuilds are triggered by #TUs built, rather than time. This should scale
more sensibly to fast vs slow machines.
- there are two separate indexed-TU thresholds to trigger index build: 5 TUs
for the first build, 100 for subsequent rebuilds.
- rebuild is always done on the regular indexing threads, and is affected by
blockUntilIdle. This means unit/lit tests run the production configuration.
- fixed a bug where we'd rebuild after attempting to load shards, even if there
were no shards.
- the BackgroundIndexTests don't really test the subtleties of the rebuild
policy (for determinism, we call blockUntilIdle, so rebuild-on-idle is enough
to pass the tests). Instead, we expose the rebuilder as a separate class and
have fine-grained tests for it.

We may choose to promote these one day. I'm not sure they're worth their own
feature flags though.

Summary:
The existing implementation (which triggers on }) is fairly simple and
has flaws:
- doesn't trigger frequently/regularly enough (particularly in editors that type the }
for you)
- often reformats too much code around the edit
- has jarring cases that I don't have clear ideas for fixing
This implementation is designed to trigger on newline, which feels to me more
intuitive than } or ;.
It does have allow for reformatting after other characters - it has a
basic behavior and a model for adding specialized behavior for
particular characters. But at least initially I'd stick to advertising
\n in the capabilities.
This also handles comment splitting: when you insert a line break inside
a line comment, it will make the new line into an aligned line comment.
Working on tests, but want people to patch it in and try it - it's hard to
see if "feel" is right purely by looking at a test.

Summary:
LSP now reflects the declaration/definition distinction.
Language server changes:
- textDocument/definition now returns a definition if one is found, otherwise
the declaration. It no longer returns declaration + definition if they are
distinct.
- textDocument/declaration returns the best declaration we can find.
- For macros, the active macro definition is returned for both methods.
- For include directive, the top of the target file is returned for both.
There doesn't appear to be a discovery mechanism (we can't return everything to
clients that only know about definition), so this changes existing behavior.
In practice, it should greatly reduce the fraction of the time we need to show
the user a menu of options.
C++ API changes:
- findDefinitions is replaced by locateSymbolAt, which returns a
vector<LocatedSymbol> - one for each symbol under the cursor.
- this contains the preferred declaration, the definition (if found), and
the symbol name
This API enables some potentially-neat extensions, like swapping between decl
and def, and exposing the symbol name to the UI in the case of multiple symbols.

Summary:
The code tweaks are an implementation of mini-refactorings exposed
via the LSP code actions. They run in two stages:
- Stage 1. Decides whether the action is available to the user and
collects all the information required to finish the action.
Should be cheap, since this will run over all the actions known to
clangd on each textDocument/codeAction request from the client.
- Stage 2. Uses information from stage 1 to produce the actual edits
that the code action should perform. This stage can be expensive and
will only run if the user chooses to perform the specified action in
the UI.
One unfortunate consequence of this change is increased latency of
processing the textDocument/codeAction requests, which now wait for an
AST. However, we cannot avoid this with what we have available in the LSP
today.

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.

rdar://problem/46050281
llvm-svn: 347675
Summary:
Ownership and configuration:
The auto-index (background index) is maintained by ClangdServer, like Dynamic.
(This means ClangdServer will be able to enqueue preamble indexing in future).
For now it's enabled by a simple boolean flag in ClangdServer::Options, but
we probably want to eventually allow injecting the storage strategy.
New 'sync' command:
In order to meaningfully test the integration (not just unit-test components)
we need a way for tests to ensure the asynchronous index reads/writes occur
before a certain point.
Because these tests and assertions are few, I think exposing an explicit "sync"
command for use in tests is simpler than allowing threading to be completely
disabled in the background index (as we do for TUScheduler).
Bugs:
I fixed a couple of trivial bugs I found while testing, but there's one I can't.
JSONCompilationDatabase::getAllFiles() may return relative paths, and currently
we trigger an assertion that assumes they are absolute.
There's no efficient way to resolve them (you have to retrieve the corresponding
command and then resolve against its directory property). In general I think
this behavior is broken and we should fix it in JSONCompilationDatabase and
require CompilationDatabase::getAllFiles() to be absolute.
