90aeebe843 cmd/godoc: move poll sleep to top of loop
CL 196979 moved the pollInterval sleep to the bottom of the loop
with the intent of not sleeping before the first readiness check,
but that caused an unintended consequence of the sleep being skipped
when errors happen. Move it back to the top to avoid that problem.

7da961ddcf cmd/godoc: convert tests to packagestest, cover third party packages
This change converts cmd/godoc tests to use the packagestest package
in its basic integration tests. For now, those tests continue to run
in GOPATH mode only. When module support is added to cmd/godoc, then
the same tests will be made to run in module mode too.

Previously, the basic integration test covered godoc functionality
on Go packages in GOROOT only. This change also adds some third
party packages to increase test coverage. This is easy to do with
the packagestest API.

d04c33d1d0 cmd/godoc: check if server exited when waiting
Previously, the waitForServer family of helpers would wait anywhere
between 15 seconds to 2 minutes for the server to become ready.
But if there's a problem that results in the server exiting early,
that wasn't being detected quickly.

This change modifies tests to also wait for command to exit,
and fail the test quickly if so. This helps during development.

5adc67163c internal/lsp: improve completions in *ast.FieldList
Now we always expect type names inside of *ast.FieldList. This expands
the previous func signature logic to also work for *ast.StructType
and *ast.InterfaceType. For example, we will now prefer type names in
cases like:

type myStruct struct { i i<> }

Also, fix a check for anonymous fields to make sure the field is
actually embedded. This fixes cases like this to properly have no
completions:

type myStruct struct { i<> i }

where this will still give type name completions:

type myStruct struct { i<> }

I introduced a new error type source.ErrIsDefinition so source_test.go
could avoid erroring out on tests that make sure definition
identifiers have no completions.

Fixes golang/go#34412.

a044388aa5 internal/lsp: add literal completions for basic types
Normally you don't want literal candidates for basic types (e.g.
"int(0)") since you can type the literal value without the type name.
One exception is if you are creating a named basic type that
implements an interface. For example:

http.Handle("/", http.FileServer(<>))

will now give "http.Dir()" as a candidate since http.Dir is a named
string type that implements the required interface http.FileSystem.

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.

1081e67f6b internal/lsp: support running go mod tidy as a code action
This changes adds basic support for running `go mod tidy` as a code
action when a user opens a go.mod file. When we have a command
available like `go mod tidy -check`, we will be able to return edits as
part of the codeAction. For now, we execute the command directly.

This change also required a few modifications to our handling of file
kinds so that we could distinguish between a Go file and a go.mod file.

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

f68e2b6f23 internal/lsp: fix infinite recursion while fixing AST
We were recursing infinitely in cases like this:

switch true {
case true:
	go foo.F<>
}

There were three things that came together to cause this:
1. We recently starting recursively fixing broken go/defer statements.
2. In this case we were failing to swap in the correct ast.Node in for
   the *ast.BadStmt because we were only looking
   for *ast.BlockStmt (and *ast.CaseStmt has no block).
3. After 2), we weren't returning an error so the fix() code thought
   it should recurse.

Fix 2) by using reflection to swap AST nodes in a generic way. Perhaps
a bit overkill in this case, but I happened to have already written
this for an upcoming change, so I just pulled it in to fix this bug.

Fix 3) by returning an error if we fail to swap the AST nodes.

Fixes golang/go#34353.

7baacfbe02 internal/lsp: support function literal completions
Now we will offer function literal completions when we know the
expected type is a function. For example:

sort.Slice(someSlice, <>)

will offer the completion "func(...) {}" which if selected will
insert:

func(i, j int) bool {<>}

I opted to use an abbreviated label "func(...) {}" because function
signatures can be quite long/verbose with all the type names in there.

The only interesting challenge is how to handle signatures that don't
name the parameters. For example,

func HandleFunc(pattern string, handler func(ResponseWriter, *Request)) {

does not name the "ResponseWriter" and "Request" parameters. I went
with a minimal effort approach where we try abbreviating the type
names, so the literal completion item for "handler" would look like:

func(<rw> ResponseWriter, <r> *Request) {<>}

where <> denote placeholders. The user can tab through quickly if they
like the abbreviations, otherwise they can rename them.

For unnamed types or if the abbreviation would duplicate a previous
abbreviation, we fall back to "_" as the parameter name. The user will
have to rename the parameter before they can use it.

One side effect of this is that we cannot support function literal
completions with unnamed parameters unless the user has enabled
snippet placeholders.

68f92b6635 go/packages: remove go.mod files
Files named go.mod define a module boundary and punch a hole in the
repository when the module is fetched with go get. We had a couple in
testdata. Get rid of them.

In one case the changes I made to produce a module cache in packagestest
were enough. In the other, the test needs multiple minor/patch versions
of the same module, which we have no provision for. Rename them to
"definitelynot_go.mod" in the repo and fix it up in the test.
