Summary:
This was originally committed in 88bccded8f,
and reverted in 93f77617ab.
This version is now much more testable: the "detect toolchain properties" part
is still not tested but also not active in tests.
All the command manipulation based on the detected properties is
directly tested, and also not active in other tests.

Remove CompileCommand too, which is also in the header.
llvm-svn: 365713
Summary:
Some custom toolchains come with their own header files and compiler
drivers. Those compiler drivers implicitly know about include search path for
those headers. This patch aims to extract that information from drivers and add
it to the command line when invoking clang frontend.

Summary:
Some projects make use of clang plugins when building, but clangd is
not aware of those plugins therefore can't work with the same compile command
arguments.
There were multiple places clangd performed commandline manipulations,
this one also moves them all into OverlayCDB.

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.

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.

Summary:
Currently, changes *within* CDBs are not tracked (CDB has no facility to do so).
However, discovery of new CDBs are tracked (all files are marked as modified).
Also, files whose compilation commands are explicitly set are marked modified.
The intent is to use this for auto-index. Newly discovered files will be indexed
with low priority.

Summary:
The new implementation is a GlobalCompilationDatabase that overlays a base.
Normally this is the directory-based CDB.
To preserve the behavior of compile_args_from=LSP, the base may be null.
The OverlayCDB is always present, and so the extensions to populate it
are always supported.
It also allows overriding the flags of the fallback command. This is
just unit-tested for now, but the plan is to expose this as an extension
on the initialize message. This addresses use cases like

Summary:
This was added in D34947 to support YCM, but YCM actually provides *all* args,
and this was never actually used.
Meanwhile, we grew another extension that allows specifying all args.
I did find one user of this extension: https://github.com/thomasjo/atom-ide-cpp.
I'll reach out, there are multiple good alternatives:
- compile_commands.txt can serve the same purpose as .clang_complete there
- we can add an extension to support setting the fallback command

Summary:
It doesn't make much sense: setting them is not coupled to opening the file,
it's an asynchronous notification.
I don't think this is a breaking change - this behavior is hard to observe!

Summary:
The CDB implementations used in open-source code are fast, and our private
slow CDB will soon do the relevant caching itself.
Simplifying the GlobalCDB layer in clangd is important to get auto-index
implemented at the right layer.

compilationDatabaseChanges in the 'workspace/didChangeConfiguration' request
This commit allows clangd to use an in-memory compilation database that's
controlled from the LSP client (-compile_args_from=lsp). It extends the
'workspace/didChangeConfiguration' request to allow the client to pass in a
compilation database subset that needs to be updated in the workspace.
Differential Revision: https://reviews.llvm.org/D49758
llvm-svn: 338597
Summary:
Caching is now handled by ClangdLSPServer and hidden behind the
GlobalCompilationDatabase interface. This simplifies ClangdServer.
This change also removes the SkipCache flag from addDocument,
which is now obsolete.
No behavioral changes are intended, the clangd binary still caches the
compile commands on the first read.

Summary:
Implementation of DidChangeConfiguration notification handling in
clangd. This currently only supports changing one setting: the path of
the compilation database to be used for the current project. In other
words, it is no longer necessary to restart clangd with a different
command line argument in order to change the compilation database.

Summary:
- GlobalCompilationDatabase now returns a single command (that's all we use)
- fallback flags are now part of the GlobalCompilationDatabase.
There's a default implementation that they can optionally customize.
- this allows us to avoid invoking the fallback logic on two separate codepaths
- race on extra flags fixed by locking the mutex
- made GCD const-correct (DBGCD does have mutating methods)

Summary:
This commit restores r303067(reverted by r303094) and fixes the 'formatting.test'
failure.
The failure is due to destructors of `ClangdLSPServer`'s fields(`FixItsMap` and
`FixItsMutex`) being called before destructor of `Server`. It led to the worker
thread calling `consumeDiagnostics` after `FixItsMutex` and `FixItsMap`
destructors were called.
Also, clangd is now run with '-run-synchronously' flag in 'formatting.test'.
