Haojian Wu a7fd548a4f [clang-rename] Fix the missing template constructors.
Summary:
When renaming a class with template constructors, we are missing the
occurrences of the template constructors, because getUSRsForDeclaration doesn't
give USRs of the templated constructors (they are not in the normal `ctors()`
method).

Jan Korous efcf643000 Reland "[clangd][test] Disable a particular testcase in FindExplicitReferencesTest when LLVM_ENABLE_EXPENSIVE_CHECKS""
The test got re-enabled after d54d71b67e landed.

However it seems that the order is still not deterministic as it
currently passes with -DLLVM_ENABLE_EXPENSIVE_CHECKS=OFF but randomly
fails with expensive checks ON.

[clangd] Add a flag for spelled references in the Index
This patch allows the index does to provide a way to distinguish
implicit references (e.g. coming from macro expansions) from the spelled
ones. The corresponding flag was added to RefKind and symbols that are
referenced without spelling their name explicitly are now marked
implicit. This allows fixing incorrect behavior when renaming a symbol
that was referenced in macro expansions would try to rename macro
invocations.

Sam McCall 92570718a8 [clangd] Mechanism to make update debounce responsive to rebuild speed.
Summary:
Currently we delay AST rebuilds by 500ms after each edit, to wait for
further edits. This is a win if a rebuild takes 5s, and a loss if it
takes 50ms.

This patch sets debouncepolicy = clamp(min, ratio * rebuild_time, max).
However it sets min = max = 500ms so there's no policy change or actual
customizability - will do that in a separate patch.

Benjamin Kramer 777180a32b [ADT] Make StringRef's std::string conversion operator explicit

Benjamin Kramer adcd026838 Make llvm::StringRef to std::string conversions explicit.
This is how it should've been and brings it more in line with

This is mostly mechanical from a custom clang-tidy check, with a lot of
manual fixups. It uncovers a lot of minor inefficiencies.

This doesn't actually modify StringRef yet, I'll do that in a follow-up.

Sam McCall 7d20e80225 [clangd] Show background index status using LSP 3.15 work-done progress notifications
Summary:
It simply shows the completed/total items on the background queue, e.g.
 indexing: 233/1000
The denominator is reset to zero every time the queue goes idle.

The protocol is fairly complicated here (requires creating a remote "progress"
resource before sending updates). We implement the full protocol, but I've added
an extension allowing it to be skipped to reduce the burden on clients - in
particular the lit test takes this shortcut.

The addition of background index progress to DiagnosticConsumer seems ridiculous
at first glance, but I believe that interface is trending in the direction of
"ClangdServer callbacks" anyway. It's due for a rename, but otherwise actually
fits.

Sam McCall d3260bf5b2 [clangd] Errors in TestTU cause test failures unless suppressed with error-ok.
Summary:
The historic behavior of TestTU is to gather diagnostics and otherwise ignore
them. So if a test has a syntax error, and doesn't assert diagnostics, it
silently misbehaves.
This can be annoying when developing tests, as evidenced by various tests
gaining "assert no diagnostics" where that's not really the point of the test.

This patch aims to make that default behavior. For the first error
(not warning), TestTU will call ADD_FAILURE().

This can be suppressed with a comment containing "error-ok". For now that will
suppress any errors in the TU. We can make this stricter later -verify style.
(-verify itself is hard to reuse because of DiagnosticConsumer interfaces...)
A magic-comment was chosen over a TestTU option because of table-driven tests.

In addition to the behavior change, this patch:
  - adds //error-ok where we're knowingly testing invalid code
    (e.g. for diagnostics, crash-resilience, or token-level tests)
  - fixes a bunch of errors in the checked-in tests, mostly trivial (missing ;)
  - removes a bunch of now-redundant instances of "assert no diagnostics"

[clangd] Fix rename for explicit destructor calls
When triggering rename of the class name in the code with explicit destructor
calls, rename fails. Consider the following piece of code:

```
class Foo;

...

Foo f;
f.~/*...*/Foo();
```

`findExplicitReferences` will report two `ReferenceLoc` for destructor call:
one is comming from `MemberExpr` (i.e. destructor call itself) and would point
to the tilde:

```
f.~/*...*/Foo();
  ^
```

And the second one is pointing to the typename and is coming from `TypeLoc`.

```
f.~/*...*/Foo();
          ^
```

This causes rename to produce incorrect textual replacements. This patch
updates `MemberExpr` handler to detect destructor calls and prevents it
from reporting a duplicate reference.

Utkarsh Saxena 734aa1d133 [clangd] Publish xref for macros from Index and AST.
Summary:
With this patch the `findReferences` API will return Xref for macros.
If the symbol under the cursor is a macro then we collect the references to it from:
1. Main file by looking at the ParsedAST. (These were added to the ParsedAST in https://reviews.llvm.org/D70008)
2. Files other than the mainfile by looking at the:
	* static index (Added in https://reviews.llvm.org/D70489)
	* file index (Added in https://reviews.llvm.org/D71406)
This patch collects all the xref from the above places and outputs it in `findReferences` API.

[clangd] Adjust diagnostic range to be inside main file
Summary:
LSP requires diagnostics to lay inside main file. In clangd we keep
diagnostics in three different cases:
- already in main file
- adjusted to a header included in main file
- has a note covering some range in main file

In the last case, we were not adjusting the diagnostics range to be in main
file, therefore these diagnostics ended up pointing some arbitrary locations.

This patch fixes that issue by adjusting the range of diagnostics to be the
first note inside main file when converting to LSP.

Kazuaki Ishizaki b7ecf1c1c3 NFC: Fix trivial typos in comments 2020-01-04 10:28:41 -05:00
Sam McCall f06f439fad [clangd] targetDecl() returns only NamedDecls.
Summary:
While it's perfectly reasonable for non-named decls such as
static_assert to resolve to themselves:
 - nothing else ever resolves to them
 - features based on references (hover, highlight, find refs etc) tend
   to be uninteresting where only trivial references are possible
 - returning NamedDecl is a more convenient API (we cast to it in many places)
 - this aligns closer to findExplicitReferences/explicitReferenceTargets

This fixes a crash in explicitReferenceTargets: if the target is a
non-named decl then there's an invalid unchecked cast to NamedDecl.

In practice this means when hovering over e.g. a static_assert:
 - before ac3f9e4842, we would show a (boring) hover card
 - after ac3f9e4842, we would crash
 - after this patch, we will show nothing

[clangd] Fix handling of inline/anon namespaces and names of deduced types in hover
Summary:
Clangd normally skips inline and anon namespaces while printing nested name
specifiers. It also drops any tag specifiers since we make use of `HoverInfo::Kind`
instead of some text in `HoverInfo::Name`

There was a bug causing us to print innermost inline/anon namespace, this patch
fixes that by skipping those.
Also changes printing and kind detection of deduced types to be similar to decl
case.

Also improves printing for lambdas, currently clangd prints lambdas as
`(anonymous class)`, we can improve it by at least printing `(lambda)`
instead.

Sam McCall b60896fad9 [clangd] Fall back to selecting token-before-cursor if token-after-cursor fails.
Summary:
The problem:

LSP specifies that Positions are between characters. Therefore when a position
(or an empty range) is used to target elements of the source code, there is an
ambiguity - should we look left or right of the cursor?

Until now, SelectionTree resolved this to the right except in trivial cases
(where there's whitespace, semicolon, or eof on the right).
This meant that it's unable to e.g. out-line `int foo^()` today.

Complicating this, LSP notwithstanding the cursor is *on* a character in many
editors (mostly terminal-based). In these cases there's no ambiguity - we must
"look right" - but there's also no way to tell in LSP.

(Several features currently resolve this by using getBeginningOfIdentifier,
which tries to rewind and supports end-of-identifier. But this relies on
raw lexing and is limited and buggy).

Precedent: well - most other languages aren't so full of densely packed symbols
that we might want to target. Bias-towards-identifier works well enough.
MS C++ for vscode seems to mostly use bias-toward-identifier too.
The problem with this solution is it doesn't provide any way to target some
things such as the constructor call in Foo^(bar());

Presented solution:

When an ambiguous selection is found, we generate *both* possible selection
trees. We try to run the feature on the rightward tree first, and then on the
leftward tree if it fails.

This is basically do-what-I-mean, the main downside is the need to do this on
a feature-by-feature basis (because each feature knows what "fail" means).
The most complicated instance of this is Tweaks, where the preferred selection
may vary tweak-by-tweak.

Wrinkles:

While production behavior is pretty consistent, this introduces some
inconsistency in testing, depending whether the interface we're testing is
inside or outside the "retry" wrapper.

In particular, for many features like Hover, the unit tests will show production
behavior, while for Tweaks the harness would have to run the loop itself if
we want this.

Summary:

- our index uses the spelling location;

This patch makes our index use file locations for references, which is
consistent with AST-based xrefs, and kythe as well.

[clangd] Define out-of-line qualify function name
Summary:
When moving function definitions to a different context, the function
name might need a different spelling, for example in the header it might be:

```
namespace a {
  void foo() {}
}
```

And we might want to move it into a context which doesn't have `namespace a` as
a parent, then we must re-spell the function name, i.e:
```
void a::foo() {}
```

This patch implements a version of this which ignores using namespace
declarations in the source file.

Sam McCall 19daa21f84 [clangd] Rethink how SelectionTree deals with macros and #includes.
Summary:
The exclusive-claim model is successful at resolving conflicts over tokens
between parent/child or siblings. However claims at the spelled-token
level do the wrong thing for macro expansions, where siblings can be
equally associated with the macro invocation.
Moreover, any model that only uses the endpoints in a range can fail when
a macro invocation occurs inside the node.

To address this, we use the existing TokenBuffer in more depth.
Claims are expressed in terms of expanded tokens, so there is no need to worry
about macros, includes etc.

Once we know which expanded tokens were claimed, they are mapped onto
spelled tokens for hit-testing.
This mapping is fairly flexible, currently the handling of macros is
pretty simple (map macro args onto spellings, other macro expansions onto the
macro name token).
This mapping is in principle token-by-token for correctness (though
there's some batching for performance).

The aggregation of the selection enum is now more principled as we need to be
able to aggregate several hit-test results together.

For simplicity i removed the ability to determine selectedness of TUDecl.
(That was originally implemented in 90a5bf92ff97b1, but doesn't seem to be very
important or worth the complexity any longer).

The expandedTokens(SourceLocation) helper could be added locally, but seems to
make sense on TokenBuffer.

[clangd] Improve symbol qualification in DefineInline code action
Summary:
Currently define inline action fully qualifies any names in the
function body, which is not optimal and definitely natural.

This patch tries to improve the situation by dropping any name
specifiers shared by function and names spelled in the body. For example
if you are moving definition of a function in namespace clang::clangd,
and body has any decl's coming from clang or clang::clangd namespace,
those qualifications won't be added since they are redundant.

It also drops any qualifiers that are visible in target context.

Sam McCall 765b1250f6 [clangd] Untangle Hover from XRefs, move into own file.
Summary:
This is mostly mechanical, with a few exceptions:
 - getDeducedType moved into AST.h where it belongs. It now takes
   ASTContext instead of ParsedAST, and avoids using the preprocessor.
 - hover now uses SelectionTree directly rather than via
   getDeclAtPosition helper
 - hover on 'auto' used to find the decl that contained the 'auto' and
   use that to set Kind and documentation for the hover result.
   Now we use targetDecl() to find the decl matching the deduced type instead.
   This changes tests, e.g. 'variable' -> class for auto on lambdas.
   I think this is better, but the motivation was to avoid depending on
   the internals of DeducedTypeVisitor. This functionality is removed
   from the visitor.

Haojian Wu 4f80fc2491 [clangd] Implement rename by using SelectionTree and findExplicitReferences.
Summary:
With the new implemenation, we will have better coverage of various AST
nodes, and fix some known/potential bugs.

Also added the existing clang-renamae tests. Known changed behavior:
 - "~Fo^o()" will not trigger the rename, will fix afterwards
 - references in macro bodies are not renamed now

Sam McCall a433e7141f [AST] Attach comment in `/** doc */ typedef struct A {} B` to B as well as A.
Summary:
Semantically they're the same thing, and it's important when the underlying
struct is anonymous.

There doesn't seem to be a problem attaching the same comment to multiple things
as it already happens with `/** doc */ int a, b;`

This affects an Index test but the results look better (name present, USR points
to the typedef).

Sam McCall 713c30b389 [clangd] Don't consider class template params part of constructor name.
Summary:
This is shorter and usually the extra info is noise.
There are cases where the params become type-parameter-0-0 that are hard to fix.

This affects a few features:
 - 'name' field in structured hover API (not exposed yet)
 - 'name' field in locateSymbolAt (not exposed in LSP)
 - 'document/symbol' - the symbol is hierarchically nested in the class
   template, or written as foo<t>::foo when defined out-of-line.

Added a test case for hover from https://github.com/clangd/clangd/issues/76.
This patch fixes one field, but no fewer than four others are wrong!
I'll fix them...

Sam McCall ad9fd32009 [clangd] Fix SelectionTree behavior on constructor init-lists.
Summary:
For the constructor Foo() : classmember(arg) {}

The AST looks like:
 - CXXCtorInitializer  classmember(arg)
   - CXXConstructExpr  classmember(arg)
     - DeclRefExpr:                arg

We want the 'classmember' to be associated with the CXXCtorInitializer, not the
CXXConstructExpr. (CXXConstructExpr is known to have bad ranges).
So just early-claim it.

Thanks @hokein for tracking down/reducing the bug.

Summary:
we have a few places using `ASTCtx.getLangOpts().IsHeaderFile` to
determine a header file, but it relies on "-x c-header" compiler flag,
if the compilation command doesn't have this flag, we will get a false
positive. We are encountering this issue in bazel build system.

To solve this problem, we infer the file from file name, actual changes will
come in follow-ups.

Sam McCall bbcbb10e2d [clangd] Ignore more implicit nodes in computing selection.
Summary:
The DeclRefExpr for the callee of overloaded `operator()` and `operator[]` are
assigned the range of the paren/bracket lists in the AST.
These are better thought of as implicit (at least `()` - `[] is murkier).
But there's no bit on Expr for implicit, so just ignore them on our side.

While here, deal with the case where an implicit stmt (e.g. implicit-this)
is wrapped in an implicit cast. Previously we ignored the statement but not
the cast, and so the cast ended up being selected.

headers, the function definition doesn't contain any documentation, cases like:

```
foo.h
// this is foo.
void foo();
foo.cc

void foo() {}
```
we should still show documentation from the foo declaration.

Ilya Biryukov 87e0cb4f1a [clangd] Implement semantic highlightings via findExplicitReferences
Summary:
To keep the logic of finding locations of interesting AST nodes in one
place.

The advantage is better coverage of various AST nodes, both now and in
the future: as new nodes get added to `findExplicitReferences`, semantic
highlighting will automatically pick them up.

The drawback of this change is that we have to traverse declarations
inside our file twice in order to highlight dependent names, 'auto'
and 'decltype'. Hopefully, this should not affect the actual latency
too much, most time should be spent in building the AST and not
traversing it.
