Also, make the protocol part of the default URL regex non-optional, as
the alternative is that any string of the format "foo.bar" will appear

We now support taking the address of objects to make better completion
candidates. For example:
i := 123
var p *int = <> // now you get a candidate for "&i"
This required that we track addressability better, particularly when
searching for deep candidates. Now each candidate knows if it is
addressable, and the deep search propagates addressability to child
candidates appropriately.
The basic propagation logic is:
- In-scope *types.Var candidates are addressable. This handles your
basic "foo" variable whose address if "&foo".
- Surrounding selector is addressable based on type checker info. This
knows "foo.bar.<>" is addressable but "foo.bar().<>" isn't
- When evaluating deep completions, fields after a function call lose
addressability, but fields after a pointer regain addressability. For
example, "foo.bar()" isn't addressable, but "foo.bar().baz" is
addressable if "bar()" returns a pointer.

This is the start of a significant refactoring to implementations,
references, and rename (i.e. everything that searches across
packages). The main goal of the refactoring is to push the package
variant logic from internal/lsp into internal/source so that all users
of source benefit, not just internal/lsp. It also makes it easier to
write tests for various cases because the source tests invoke the
source package directly (so previously did not include all the package
variants).
Currently source.Identifer() handles lots of disparate use cases.
Things like definition and hover don't care about package variants but
do care about other random bits of info that may not apply to
implementations or references. So, I'm splitting implementations out
from source.Identifier. As I work through references and rename
hopefully things will end up separated into smaller chunks.
I also improved implementation deduping to happen earlier. I thought I
could dedupe using obj.Pos(), but mirror objects in package variants
have different positions (suggesting they aren't reusing the
same *ast.File). Instead I used token.Position to dedupe.

The situation in golang/go#35638 was as follows:
didOpen main.go creates a snapshot that knows main.go is in package
"mod.com".
didChange main.go creates a snapshot. When a file changes, we discard
its contents by leaving the file handle out of the "files" map.
didOpen const.go creates a snapshot, and attempts to invalidate the
metadata for packages in the same directory.
The way we detect packages in the same directory is by iterating through
the files in the snapshot. But we threw away the only file in "mod.com"
in step 2 when its contents changed. If a diagnostics run happened to
get in between the two steps, it would re-load main.go and the bug would
go away. If not, step 3 would find no files and fail to invalidate
"mod.com".
The best way to fix this is to insert the new file handle eagerly during
cloning. That way there's no confusion.

Sometimes you do want "nil", but it's such a short identifier you
probably aren't leaning too heavily on autocompletion. I think it
makes sense to optimize for the case when you want something non-nil.

We previously searched the reverse dependencies of the "widest"
package that contained out starting identifier, but if our package has
tests then the widest package is the ".test" variant, and it has no
reverse dependencies. Fix by searching through all of the packages
that contain our starting identifier.
For example:
-- foo/foo.go --
package foo
func Foo() {}
-- foo/foo_test.go --
package foo
func TestFoo(t *testing.T) {}
-- bar/bar.go --
import "foo"
func _() {
foo.Foo()
}
We would start searching from the foo.test variant, but we wouldn't
search package bar at all because bar does not import foo.test, it
imports plain foo. Now we search from both foo and foo.test (you still
need search foo.test to find references within foo_test.go).

Say you have foo.go and foo_test.go yielding packages "foo" and

invalidate the foo.test and foo packages. Invalidating foo is not
necessary since it does not depend on any test files. Furthermore, it
caused problems because nothing would refetch foo's metadata until
foo.go changed, so various things (such as finding implementations in
packages that depend on "foo") would be broken.
Now we only invalidate metadata from packages that contain the
modified file. We only invalidate type info from packages that contain
the modified file, or from such packages' transitive reverse

We previously only searched for implementations of the object we found
in the "widest" package variant. We instead need to search all
variants because each variant is type checked separately, and
implementations can be located in packages associated with different
variants.
For example, say you have:
-- foo/foo.go --
package foo
type Foo int
type Fooer interface { Foo() Foo }
-- foo/foo_test.go --
package foo
func TestFoo(t *testing.T) {}
-- bar/bar.go --
package bar
import "foo"
type impl struct {}
func (impl) Foo() foo.Foo { return 0 }
When you run find-implementations on the Fooer interface, we
previously would start from the (widest) foo.test's Fooer named
type. Unfortunately bar imports foo, not foo.test, so bar.impl
does not implement foo.test.Fooer. The specific reason is that
bar.impl.Foo returns foo.Foo, whereas foo.test.Fooer.Foo returns
foo.test.Foo, which are distinct *types.Named objects.
Starting our search instead from foo.Fooer resolves this issue.
However, we also need to search from foo.test.Fooer so we match any
implementations in foo_test.go.

When searching for implementations we look at all packages in the
workspace. We do a full parse since we need to look for non-exported
types and look in functions for type declarations. However, we always
type check a package's dependencies in export-only mode to save work.
This leads to what I call the "two world" syndrome where you have both
the export-only and full-parse versions of a package in play at once.
This is problematic because mirror objects in each version do not
compare equal.
For example:
-- a/a.go --
package a
type Breed int
const Mutt Breed = 0
type Dog interface{ Breed() Breed }
-- b/b.go --
package b
import "a"
type dog struct{}
func (dog) Breed() a.Breed { return a.Mutt }
---
In this situation, the problem is "b" loads its dependency "a" in
export only mode so it gets one version of the "a.Breed" type. The
user opens package "a" directly so it gets fully type checked and has
a second version of "a.Breed". The user searches for "a.Dog"
implementations, but "b.dog" does not implement the fully-loaded
"a.Dog" because it returns the export-only version of the "a.Breed"
type.
Fix it by always loading in-workspace dependencies in full parse mode.
We need to load them in full parse mode anyway if the user does find
references or find implementations.
In writing a test I fixed an incorrect import in the testdata. This
uncovered an unrelated bug which made a different implementation test
very flaky. I disabled it for now since I couldn't see a fix simple
enough to slip into this commit.

Sometimes the prefix of the thing you want to complete is a keyword.
For example:
variance := 123
fmt.Println(var<>)
In this case the parser produces an *ast.BadExpr which breaks
completion. We now repair this BadExpr by replacing it with
an *ast.Ident named "var".
We also repair empty decls using a similar approach. This fixes cases
like:
var typeName string
type<> // want to complete to "typeName"
We also fix accidental keywords in selectors, such as:
foo.var<>
The parser produces a phantom "_" in place of the keyword, so we swap
it back for an *ast.Ident named "var".
In general, though, accidental keywords wreak havoc on the AST so we
can only do so much. There are still many cases where a keyword prefix
breaks completion. Perhaps in the future the parser can be
cursor/in-progress-edit aware and turn accidental keywords into
identifiers.
Fixesgolang/go#34332.
PS I tweaked nodeContains() to include n.End() to fix a test failure
against tip related to a change to go/parser. When a syntax error is
present, an *ast.BlockStmt's End() is now set to the block's final
statement's End() (earlier than what it used to be). In order for the

The early return logic for didOpen events in
(*snapshot).invalidateContent was preventing the creation of a new
snapshot, which was in turn stopping the versions from being updated.
This exposed a fundamental issue in the way we were calculating
workspace diagnostics. Since we weren't waiting for diagnostics to be
completed for an entire snapshot before replying that the server had
been initialized, snapshots were being cloned without any type
information. For quickfix code actions, we assume that we have all
information cached (since we need to have sent the diagnostics that the
quickfix is mapped to), so we were not finding the cached analysis
results.
To handle this in the short-term, we key analyses by their names, and
then regenerate results as-needed for code actions. This is technically
more correct than simply assuming that we have the analyses cached. In a
follow-up CL, I will send a follow-up that will make sure that
snapshots "wait" on each other to be fully constructed before being
cloned.

I also improved the literal struct snippet to not leave the cursor

Previously it was only checking if the struct had no fields at all.
This means after completing in the above example you will end up with
"bytes.Buffer{}<>" instead of "bytes.Buffer{<>}", where "<>" denotes

Paul Jolly observes that returning interface{} is not helpful.
Now CodeAction() returns []CodeAction.
The type in typescript is (Command | CodeAction)[] | null
but the choice is up to gopls, which returns []CodeAction.

Code generation has been unified, so that tsprotocol.go and tsserver.go
are produced by the same program. tsprotocol.go is about 900 lines shorter,
partly from removing boilerplate comments that golint no longer requires.
(And partly by generating fewer unneeded types.)
The choice made for a union type is commented with the set of types. There
is no Go equivalent for union types, but making themn all interface{}
would replace type checking at unmarshalling with checking runtime
conversions.
Intersection types (A&B) are sometimes embedded (struct{A;B;}, and
sometimes expanded, as they have to be if A and B have fields with the
same names.
There are fewer embedded structs, which had been verbose and confusing to
initialize. They have been replaced by types whose names end in Gn.
Essentially all the generated *structs have been removed. This makes
no difference in what the client sends, and the server may send a {}
where it previously might have sent nothing. The benefit is that some
nil tests can be removed. Thus 'omitempty' in json tags is just
documentation that the element is optional in the protocol.
The files that generate this code will be submitted later, but soon.

In cases like:
var foo []io.Writer
var buf *bytes.Buffer
foo = append(foo, <>)
we weren't giving "buf" a good score. When comparing the candidate
type *bytes.Buffer to the (variadic) expected type []io.Writer we were
turning the candidate type into []*bytes.Buffer. However, of course,
[]*bytes.Buffer is not assignable to []io.Writer, so the types didn't
match. Now we instead turn the expected type []io.Writer into
io.Writer and compare to *bytes.Buffer.
I fixed the @rank test note to check that the candidates' scores are
strictly decreasing. Previously it would allow candidates with the
same score if they happened to be in the right order. This made it
easier to right a test for this issue, but also uncovered an issue
with untyped completion logic. I fixed it to do the untyped constant
check if _either_ the expected or candidate type is
untyped (previously it required the candidate type to be untyped).

When looking for references, look in the entire workspace rather than
the same package. This makes the references query more expensive because
it needs to look at every package in the workspace, but hopefully
it shouln't be user-noticable. This can be made more efficient by only
checking packages that are transitive reverse dependencies. I don't think a
mechanism to get all transitive reverse dependencies exists yet.
One of the references test have been changed: it looked up references
of the builtin int type, but now there are so many refererences that
the test too slow and doesn't make sense any more. Instead look up
references of the type "i" in that file.

This change is the first step in centralizing control of modifications
to different files, either within the workspace or outside of it. We add
a source.FileAction type to pass into the internal/lsp/cache package and
handle the difference between opening and creating a file.
Now that we load all packages in a workspace by default, we no longer
need to re-load a file on open. This CL should enable CL 206883 to work
correctly.
