cfcbc7796e internal/lsp: improve link in documentation on hover
This change refactors some of the logic that builds a link anchor for
a given symbol, pushing the actual Link into the HoverInformation struct.
This is necessary because type information is needed to build up that
link in certain cases, like methods.

The last step will be to correctly display struct fields.

69a79c76c7 internal/lsp: add some minimal validation for client capabilities
We've had a couple of breakages with changes to the protocol that are
bugs on our end. It's hard to review changes to the protocol, and it's
not reasonable to expect that we would remember the correct types for
everything, so we should have a test that validates some basic expectations
about the expected responses. We can add more here as issues come up.

Also, change RenameProvider back to an interface.

likely users don't want to see staticcheck reports for every

that showed up when we ran gopls with staticcheck on x/tools.

Finally, made sure that we don't send empty diagnostics when diagnosing
the snapshot on start-up, as that is not necessary.

This change runs diagnostics on all packages in the workspace, instead

information for a newly-opened file (since we should have it be default

This causes a large increase in memory usage in the
internal/lsp/cmd tests, so to handle that, share an app between all of
the tests, rather than creating one per-test type.

5091d647ee internal/lsp: reorganize the generated Go code for the lsp protocol
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 They have been replaced by types whose names end in Gn.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.

caa0b0f7d5 internal/lsp/source: add support for references in the same workspace
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.

6d8f1af9cc tools/gopls: add cmd support for signature
This change adds command line support for signatureHelp.
If the location provided corresponds to a function, that
function signature is displayed. In case that function is
documented the related comment is shown as well.

Example:

$ gopls signature ~/tmp/foo/main.go:7:5
$
$ Next(n int) []byte
$
$ Next returns a slice containing the next n bytes from
$ the buffer, advancing the buffer as if the bytes had been
$ returned by Read.

Note that linebreaks shown in the comment are just to adhere
commit message guidelines. The command prints documentation
comments on one line.

This commit adds support for calling rename from the gopls command
line, e.g.

$ gopls rename -w ~/tmp/foo/main.go:8:6
$ gopls rename -w ~/tmp/foo/main.go:#53

Optional arguments are:

- -w, which writes the changes back to the original file; and
- -d, which prints a unified diff to stdout

With no arguments, the changed files are printed to stdout.

It:

- adds internal/lsp/cmd/rename.go, which implements the command;
- adds "rename" to the list of commands in internal/lsp/cmd/cmd.go;
- removes the dummy test from internal/lsp/cmd/cmd_test.go; and
- adds internal/lsp/cmd/rename_test.go, which uses the existing
  "golden" data to implement its tests.

5adc211bf7 tools/internal/tool: refactor tool.Main() for testabilty
In it previous implementation, tool.Main was meant to be called from
an applications main().  If it encountered an error it would print the
error to standard error and exit with a non-zero status (2).

It is also called recursively and in various test functions.

Exiting on an error makes testing difficult, unnecessarily.

This change breaks the functionality into to parts: an outer
tool.MustMain() that is intended to be called by main() functions and
an inner Main that is used by MustMain() and by test functions.

None of the existing test functions use Main()'s error value, but the
failure case tests for the command line invocation of rename (#194878)
require it.

Fixes #34291

11affa06ff internal/lsp: show errors when the user is in the wrong directory
If we encounter `go list` errors when loading a user's package, we
should try to see if they've encountered any of our common error cases.
They are: 1) a user has GO111MODULE=off, but is outside of their GOPATH,
and 2) a user is in module mode but doesn't have a go.mod file.

Fortunately, go/packages does a great job handling edge cases so gopls
will work well for most of them. The main issue will be unresolved
imports. These show up in DepErrors in `go list`, so go/packages doesn't
propagate them through to the list of errors. This will require changes
to go/packages.

d151469ab0 x/tools/gopls: reimplement rpc logging at a lower level
Over time the existing implementation became buggy. This implementation
logs close to where data is read or written from the stream connected
to the client. As is required, the log records are from the point of view
of the client.

Fixes golang/go#33755

773fe550c1 gopls: return file error if file open fails
The bug manifests itself when a non-existent file is passed in as an
argument to gopls, causing a nil pointer dereference panic. This is due
to an attempt to reference the "mapper" attribute, which is not set if
the file is not found.

The resolution is to check for an informative error that is set on the
file instance after "getFile" is called and return it immediately to the
caller to allow the error to propagate up to the main() function and
print the error to stdout.

Testing:
--------

Non-existent file:
$ gopls -rpc.trace -v check gopls/doesnotexist.go
check: file:///Users/albertteoh/repo/tools/gopls/doesnotexist.go: open /Users/albertteoh/repo/tools/gopls/doesnotexist.go: no such file or directory

Existing go file:
$ gopls -rpc.trace -v check internal/lsp/definition.go

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.
