19ff4fff88 go/packages: avoid loading some packages in when computing overlays
In some cases, it's safe to avoid loading additional packages

Avoid some unnecessary loads when it's completely safe to do so.

4298585011 internal/lsp: provide deep completion candidates
Deep completion refers to searching through an object's fields and
methods for more completion candidates. For example:

func wantsInt(int) { }
var s struct { i int }
wantsInt(<>)

Will now give a candidate for "s.i" since its type matches the
expected type.

We limit to three deep completion results. In some cases there are
many useless deep completion matches. Showing too many options defeats
the purpose of "smart" completions. We also lower a completion item's
score according to its depth so that we favor shallower options. For
now we do not continue searching past function calls to limit our
search scope. In other words, we are not able to suggest results with
any chained fields/methods after the first method call.

Deep completions are behind the "useDeepCompletions" LSP config flag
for now.

4874f863e6 internal/jsonrpc2: change the concurrency strategy
This abandons the limited size queue
Instead we kick a go-routine per request, but have each request wait for the
previous request to say it is okay to continue. This allows each request to
control when it is finished with tasks that required strict ordering without
every blocking the routine that handles replies.
It also protects against repeated or missing replies.

of propagating the canceled error.

5d636af2a9 internal/lsp: improve completion support for type assertions
In type assertion expressions and type switch clauses we now infer the
type from which candidates must be assertable. For example in:

var foo io.Writer
bar := foo.(<>)

When suggesting concrete types we will prefer types that actually
implement io.Writer.

I also added support for the "*" type name modifier. Using the above
example:

bar := foo.(*<>)

we will prefer type T such that *T implements io.Writer.

3cbd95df51 internal/lsp: support a file belonging to multiple packages
This change adds supports for a package belonging to multiple files.
It requires additional packages.Loads for all of the packages to which a
file belongs (for example, if a non-test file also belongs to a package's
test variant).

For now, we re-run go/packages.Load for each file we open, regardless of
whether or not we already know about it.

This solves the issue of packages randomly belonging to a test or not.
Follow-up work needs to be done to support multiple packages in
references, rename, and diagnostics.

494e18b268 internal/lsp: send client expected rename provider
This change sends the expected boolean value for 'renameProvider'
to the client.

When a client does not send 'prepareSupport' in its initial
'initialize' request, the client expects to get a boolean value for
'renameProvider'. Since we do not yet provide prepare support, we just
set 'renameProvider' to true regardless of the value of prepareSupport.

Fixes golang/go#32703

431033348d internal/lsp: fix function value completions
Previously we would always expand *types.Func completion candidates to
function calls, even if the expected type matched the function itself,
not its return value. Now we check the function itself before we check
its return value. This fixes cases like this:

func foo() int { return 0 }
var f func() int
f = <foo> // now completes to "foo" instead of "foo()"

Also, *types.Var function values were never getting expanded to calls.
I fixed the completion formatting to know that both *types.Func
and *types.Var objects might need to be invoked in the completion
item. This fixes cases like this:

foo := func() int { return 0 }
var i int
i = <foo()> // now completes to "foo()" instead of "foo"

4adf7a708c internal/lsp: add identifier renaming
This change provides support to rename identifiers within a single
package.

The renaming is performed by finding all references to an identifier,
and then creating text edits to replace the existing text with the
new identifier.

Editing an import spec is not supported.

22e91af008 internal/lsp: apply type modifiers to completion candidate
In situations like:

var buf bytes.Buffer
var w io.Writer = &b<>

if we want to complete to "buf" properly we need to apply the "&" type
modifier to buf's type of bytes.Buffer to see that it is assignable
to type io.Writer. Previously we applied type modifiers in reverse to
the "expected" type (io.Writer in this case), but that is obviously
incorrect in this situation since it is nonsensical to
dereference (the reverse of "&") io.Writer.

b76e30ffa0 internal/lsp: fix references for type switch vars
Implicit local variables for type switches do not appear in the Uses
map and do not have objects associated with them.  This change
associates all of the different types objects for the same local type
switch declaration with one another in the declaration.

The identifier for the implicit local variable does not have a type but
does have declaration objects.

Find references for type switch vars will return references to all the
identifiers in all of the case clauses and the declaration.

da514acc47 internal/lsp: suggest completions that satisfy interfaces
When checking if a completion candidate matches the expected type at
the cursor position, we now use types.AssignableTo instead of
types.Identical. This properly handles cases like using a concrete
type to satisfy an interface type.

Calling AssignableTo triggered some crashes related to the fake
"resolved" types we create. Their underlying type was nil, which is
not allowed. We now set their underlying type to the invalid type.

I've also rearranged things so expected type information lives in a
dedicated typeInference struct. For now there is no new information added,
but in subsequent commits there will be more metadata about the
expected type.
