Sam McCall 704cd4d5d0 [clangd] Only minimally escape text when rendering to markdown.
Summary:
Conservatively escaping everything is bad in coc.nvim which shows the markdown
to the user, and we have reports of it causing problems for other parsers.

Haojian Wu 8a593e29ab [AST] Correct the CXXOperatorCallExpr source range.
Summary:
Previously, the range for "->" CXXOperatorCallExpr is the range of the
class object (not including the operator!), e.g. "[[vector_ptr]]->size()".

This patch includes the range of the operator, which fixes the issue
where clangd doesn't go to the overloaded operator "->" definition.

Utkarsh Saxena e397a0a5c3 [clangd] Add instrumentation mode in clangd for metrics collection.
Summary:
This patch adds an instrumentation mode for clangd (enabled by
corresponding option in cc_opts).
If this mode is enabled then user can specify callbacks to run on the
final code completion result.

Moreover the CodeCompletion::Score will contain the detailed Quality and
Relevance signals used to compute the score when this mode is enabled.
These are required because we do not any place in which the final
candidates (scored and sorted) are available along with the above
signals. The signals are temporary structures in `addCandidate`.

The callback is needed as it gives access to many data structures that
are internal to CodeCompleteFlow and are available once Sema has run. Eg:
ScopeDistnace and FileDistance.

If this mode is disabled (as in default) then Score would just contain 2
shared pointers (null). Thus cost(memory/time) increase for the default
mode would be fairly cheap and insignificant.

Sam McCall 2cd33e6fe6 [clangd] Track document versions, include them with diags, enhance logs
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.

Sam McCall c627b120eb [clangd] Cancel certain operations if the file changes before we start.
Summary:
Otherwise they can force us to build lots of snapshots that we don't need.
Particularly, try to do this for operations that are frequently
generated by editors without explicit user interaction, and where
editing the file makes the result less useful. (Code action
enumeration is a good example).

https://github.com/clangd/clangd/issues/298

This doesn't return the "right" LSP error code (ContentModified) to the client,
we need to teach the cancellation API to distinguish between different causes.

while clangd-rename uses the ClassTemplateDecl.
