[clangd] Fix forgotten propagation of AsnycPreamble flag 2020-06-03 23:56:49 +02:00
Konrad Kleine e636e6b79a [clang-tidy]: Added modernize-replace-disallow-copy-and-assign-macro
Summary:
This check finds macro expansions of `DISALLOW_COPY_AND_ASSIGN(Type)` and
replaces them with a deleted copy constructor and a deleted assignment operator.

Before the `delete` keyword was introduced in C++11 it was common practice to
declare a copy constructor and an assignment operator as a private members. This
effectively makes them unusable to the public API of a class.

With the advent of the `delete` keyword in C++11 we can abandon the
`private` access of the copy constructor and the assignment operator and
delete the methods entirely.

Migration example:

```
lang=dif
class Foo {
  private:
  -  DISALLOW_COPY_AND_ASSIGN(Foo);
  +  Foo(const Foo &) = delete;
  +  const Foo &operator=(const Foo &) = delete;
  };
```

[clangd] Copy existing includes in ReplayPreamble
Summary:
ReplayPreamble was just grabbing the reference of IncludeStructure
passed to it and then replayed any includes seen so while exiting
built-in file.

This implies any include seen in built-in files being replayed as part
of preamble, even though they are not. This wasn't an issue until we've
started patching preambles, as includes from built-in files were not
mapped back to main-file.

This patch copies over existing includes at the time of
ReplayPreamble::attach and only replies those to prevent any includes
from the preamble patch getting mixed-in.

[clangd] Run PreambleThread in async mode behind a flag
Summary: Depends on D80198.

This patch implies ASTs might be built with stale preambles without
blocking for a fresh one. It also drops any guarantees on every preamble
version being built. In case of multiple preamble build requests, in
addition to being debounced.

Any preamble requested with a WantDiags::Yes will always be built, this
is ensured by blocking enqueueing of any subsequent reqest.

AST worker will still block for initial preamble to reduce duplicate
work.

[clangd] locateMacroAt handles patched macros
Summary: Depends on D79992.

This patch changes locateMacroAt to perform #line directive substitution
for macro identifier locations.

We first check whether a location is inside a file included through
built-in header. If so we check whether line directive maps it back to
the main file, and afterwards use TokenBuffers to find exact location of
the identifier on the line.

Instead of performing the mapping in locateMacroAt, we could also store
a mapping inside the ParsedAST whenever we use a patched preamble. But
that would imply adding more responsibility to ParsedAST and paying for
the mapping even when it is not going to be used.

====

Go-To-Definition:

Later on these locations are used for serving go-to-definition requests,
this enables jumping to definition inside the preamble section in
presence of patched macros.

=====

Go-To-Refs:

Macro references in main file are collected separetely and stored as a
map from macro's symbol id to reference ranges. Those ranges are
computed inside PPCallbacks, hence we don't have access to TokenBuffer.

In presence of preamble patch, any reference to a macro inside the
preamble section will unfortunately have the wrong range. They'll point
into the patch rather than the main file. Hence during findReferences,
we won't get any ranges reported for those.

Fixing those requires:
- Lexing the preamble section to figure out "real range" of a patched
  macro definition
- Postponing range/location calculations until a later step in which we
  have access to tokenbuffers.

This patch trades some accuracy in favor of code complexity. We don't do
any patching for references inside the preamble patch but get any
reference inside the main file for free.

[clangd] Patch PP directives to use stale preambles while building ASTs
Summary:
Depends on D79930.

This enables more accurate parsing of the AST, by making new macro
definitions in preamble section visible. This is handled by injecting
define directives into preamble patch.

This patch doesn't handle any location mappings yet, so features like go-to-def,
go-to-refs and hover might not work as expected. These will be addressed in a
follow-up patch.

This commit adds access specifier information to the hover

public, or protected. This can be particularly useful when a developer
is in the implementation file and wants to know if a particular member
definition is public or private.

  after: 5:13
  change: -33%

Indexer.cpp libclang should be updated too, I'm less familiar with that code,
and it's doing tricky things with the ShouldSkipFunctionBody callback, so it
needs to be done separately.

Summary:
FieldDecl::getParent assumes that the FiledDecl::getDeclContext returns a

The Decls hierarchy is like following

FieldDecl <-- ObjCIvarDecl

DeclContext <-- ObjCContainerDecl <-- ObjCInterfaceDecl
         ^
         |----- TagDecl <-- RecordDecl

calling getParent() on ObjCIvarDecl will:
1. invoke getDeclContext(), which returns a DeclContext*, which points to an ObjCInterfaceDecl;
2. then downcast the "DeclContext" pointer to a RecordDecl*, and we will hit
the "is_a<RecordDecl>" assertion in llvm::cast (undefined behavior
in release build without assertion enabled);
