Haojian Wu 545c02a710 [clangd] Add line and column number to the index symbol.
Summary:
LSP is using Line & column as symbol position, clangd needs to transfer file
offset to Line & column when sending results back to LSP client, which is a high
cost, especially for finding workspace symbol -- we have to read the file
content from disk (if it isn't loaded in memory).

Saving these information in the index will make the clangd life eaiser.

Marc-Andre Laperle 90a937e3e1 [clangd] Use operator<< to prevent printers issues in Gtest
Summary:
It is possible that there will be two different instantiations of
the printer template for a given type and some tests could end up calling the
wrong (default) one. For example, it was seen in CodeCompleteTests.cpp when
printing CompletionItems that it would use the wrong printer because the default
is also instantiated in ClangdTests.cpp.

With this change, objects that were previously printed with a custom Printer now
get printed through the operator<< which is declared alongside the class.
This rule of the thumb should make it less error-prone.

Haojian Wu e9a5a2f10c [clangd] Allow using customized include path in URI.
Summary:
Calculating the include path from absolute file path does not always
work for all build system, e.g. bazel uses symlink as the build working
directory. The absolute file path from editor and clang is diverged from
each other. We need to address it properly in build sysmtem integration.

This patch worksarounds the issue by providing a hook in URI which allows
clients to provide their customized include path.

Simon Marchi 9808262ede [clangd] Support incremental document syncing
Summary:
This patch adds support for incremental document syncing, as described
in the LSP spec.  The protocol specifies ranges in terms of Position (a
line and a character), and our drafts are stored as plain strings.  So I
see two things that may not be super efficient for very large files:

- Converting a Position to an offset (the positionToOffset function)
  requires searching for end of lines until we reach the desired line.
- When we update a range, we construct a new string, which implies
  copying the whole document.

However, for the typical size of a C++ document and the frequency of
update (at which a user types), it may not be an issue.  This patch aims
at getting the basic feature in, and we can always improve it later if
we find it's too slow.

Simon Marchi 766338ad7f Make positionToOffset return llvm::Expected<size_t>
Summary:

To implement incremental document syncing, we want to verify that the
ranges provided by the front-end are valid.  Currently, positionToOffset
deals with invalid Positions by returning 0 or Code.size(), which are
two valid offsets.  Instead, return an llvm:Expected<size_t> with an
error if the position is invalid.

According to the LSP, if the character value exceeds the number of
characters of the given line, it should default back to the end of the
line.  It makes sense in some contexts to have this behavior, and does
not in other contexts.  The AllowColumnsBeyondLineLength parameter
allows to decide what to do in that case, default back to the end of the
line, or return an error.

Simon Marchi 9569fd51ac Move DraftMgr from ClangdServer to ClangdLSPServer
Summary:
This patch moves the draft manager closer to the edge of Clangd, from
ClangdServer to ClangdLSPServer.  This will make it easier to implement
incremental document sync, by making ClangdServer only deal with
complete documents.

As a result, DraftStore doesn't have to deal with versioning, and thus
its API can be simplified.  It is replaced by a StringMap in
ClangdServer holding a current version number for each file.

Summary:

(e.g. in bazel execroot) which might not be desired if the symlink points to a

might prefer to edit the file on the real path.

This change converts file paths from clangd to real path (e.g. resolving symlinks).
Long term, we might want to the symlink handling logic to clangd where clangd
can better decide whether symlinks should be resolved according to e.g. compile
commands.

Sam McCall 77a719cb9e [clangd] Fix unintentionally loose fuzzy matching, and the tests masking it.
Summary:
The intent was that [ar] doesn't match "FooBar"; the first character must match
a Head character (hard requirement, not just a low score).
This matches VSCode, and was "tested" but the tests were defective.

The tests expected matches("FooBar") to fail for lack of a match. But instead
it fails because the string should be annotated - matches("FooB[ar]").
This patch makes matches("FooBar") ignore annotations, as was intended.

Fixing the code to reject weak matches for the first char causes problems:
-  [bre] no longer matches "HTMLBRElement".
   We allow matching against an uppercase char even if we don't think it's head.
   Only do this if there's at least one lowercase, to avoid triggering on MACROS
-  [print] no longer matches "sprintf".
   This is hard to fix without false positives (e.g. [int] vs "sprintf"])
   This patch leaves this case broken. A future patch will add a dictionary
   providing custom segmentation to common names from the standard library.

Fixed a couple of index tests that indirectly relied on broken fuzzy matching.
Added const in a couple of missing places for consistency with new code.

Sam McCall d1e0deb271 [clangd] Debounce streams of updates.
Summary:
Don't actually start building ASTs for new revisions until either:
- 500ms have passed since the last revision, or
- we actually need the revision for something (or to unblock the queue)

In practice, this avoids the "first keystroke results in diagnostics" problem.
This is kind of awkward to test, and the test is pretty bad.
It can be observed nicely by capturing a trace, though.
