Aaron Ballman dda6290f16 Fix a false-positive with cert-err58-cpp.
If a variable is declared constexpr then its initializer needs to be a constant expression, and thus, cannot throw. This check is about not throwing exceptions before main() runs, and so it doesn't apply if the initializer cannot throw. This silences the diagnostic when initializing a constexpr variable and fixes PR35457.

Eric Liu 4d814a93e5 [clangd] Canonicalize file path in URIForFile.
Summary:
File paths in URIForFile can come from index or local AST. Path from
index goes through URI transformation and the final path is resolved by URI
scheme and could be potentially different from the original path. Hence, we
should do the same transformation for all paths. We do this in URIForFile, which
now converts a path to URI and back to a canonicalized path.

Summary:

Using this information, restoring from cache using compile commands becomes
possible instead of doing directory traversal. Also, we can issue indexing
actions for out-of-date headers even if source files depending on them haven't
changed.

Sam McCall 422c828dfc [clangd] Enable auto-index behind a flag.
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.

Sam McCall 6e2d2a33b6 [clangd] Auto-index watches global CDB for changes.
Summary:
Instead of receiving compilation commands, auto-index is triggered by just
filenames to reindex, and gets commands from the global comp DB internally.
This has advantages:
 - more of the work can be done asynchronously (fetching compilation commands
   upfront can be slow for large CDBs)
 - we get access to the CDB which can be used to retrieve interpolated commands
   for headers (useful in some cases where the original TU goes away)
 - fits nicely with the filename-only change observation from r347297

The interface to GlobalCompilationDatabase gets extended: when retrieving a
compile command, the GCDB can optionally report the project the file belongs to.
This naturally fits together with getCompileCommand: it's hard to implement one
without the other. But because most callers don't care, I've ended up with an
awkward optional-out-param-in-virtual method pattern - maybe there's a better
one.

This is the main missing integration point between ClangdServer and
BackgroundIndex, after this we should be able to add an auto-index flag.

Previously, removeDoc followed by an addDoc to TUScheduler resulted in

To workaround this, we tracked a version number in ClangdServer and
discarded stale diagnostics. After this commit, the TUScheduler will
stop delivering diagnostics for removed files and the workaround in
ClangdServer is not required anymore.

Eric Liu c0ac4bb17c [clangd] Cleanup: stop passing around list of supported URI schemes.
Summary:
Instead of passing around a list of supported URI schemes in clangd, we
expose an interface to convert a path to URI using any compatible scheme
that has been registered. It favors customized schemes and falls
back to "file" when no other scheme works.

Changes in this patch are:
- URI::create(AbsPath, URISchemes) -> URI::create(AbsPath). The new API finds a
compatible scheme from the registry.
- Remove URISchemes option everywhere (ClangdServer, SymbolCollecter, FileIndex etc).
- Unit tests will use "unittest" by default.
- Move "test" scheme from ClangdLSPServer to ClangdMain.cpp, and only
register the test scheme when lit-test or enable-lit-scheme is set.
(The new flag is added to make lit protocol.test work; I wonder if there
is alternative here.)

Eric Liu 5628c1455f [clangd] Cleanup: use index file instead of header in workspace symbols lit test.
