Rebecca Stambler 4c77dbd9e5 internal/lsp: fix race condition caused by config in `go mod tidy`
Reusing the config causes a race condition because it may be modified.
Get a new config in the bound function instead.

Rebecca Stambler 0eae6ac92e internal/lsp: add a test for gc annotation details code lens
This change adds a test to check the functionality of the GC details
code lens, including the behavior of toggling it on and off. This
exposed a Windows bug that was mentioned on Slack, which can be fixed by
adjusting the URI.

I also refactored a bit of the code to use a JSON decoder, which
simplifies things a little bit.

Danish Dua 8d73f17870 internal/lsp: move package selection to before type checking
This change moves package selection to before type checking so we don't
unnecessarily type-check both variants of a package. As a result, exec
time and memory usage for features making calls to GetParsedFile are cut
by half since we only type check either the narrowest or the widest
package.

Rebecca Stambler 24570c0594 internal/lsp: handle initial workspace load failure per module
This CL adds diagnostics to the go.mod file if one of the modules in
the workspace is invalid and causes the initial workspace load to fail.
When the module is fixed, the initial workspace load will be retried.

This CL also introduces the *source.ErrorList error type, which will be
useful in the future as a way of producing diagnostics out of errors.

Heschi Kreinick 82fe25c375 gopls/doc: improve enum value documentation
Add a new field to the options JSON, EnumValues. Use it to automatically
generate the documentation for enums. Fix the displayed type to be
"enum" rather than the full-qualified Go type name.

To make this easy, I changed the various enum constants to be strings,
with values matching their configuration values. It may be possible to
automatically parse them in the future, but we can get to that later.

The documentation for hoverKind's private values is a little janky. I
didn't want to build a way to hide them. We can hardcode it if we really
care.

Heschi Kreinick d56e4e40bc internal/lsp/cache: set GO111MODULE=auto in 1.16
1.16 wants to set GO111MODULE=on. There are, AFAIK, two differences
between "auto" and "on". First, if you're in a directory outside of GOPATH
and with no go.mod, "on" will run in module mode with GOMOD=os.DevNull.
I don't think we care very much about that. Second, if you're in GOPATH
with no go.mod, "on" will run in module mode, breaking GOPATH mode.

Breaking GOPATH mode may be desirable for the go command generally, but
for gopls I think it will lead to an unnecessarily bad user experience.
Users will find out when they do their first build or test; there's IMO
no need to also break their editor.

Flip the default back to "auto".

Jay Conrod 3791637d67 all: fix tests in preparation for GO111MODULE=on by default
This CL does not fix failures in ./gopls/internal/regtest, which will
be fixed separately.

In refactor/rename.TestDiff, add a go.mod file.

In internal/imports.ProcessEnv.buildContext, set an I/O hook if
GO111MODULE=off in ProcessEnv but not in the current process's
environment.

Context allows the user to set GOPATH, GOOS, GOARCH, and a few other
environment variables, but not GO111MODULE. Context.Import may return
different results than packages.Load if the latter is invoked with a
GO111MODULE value that differs from the caller's environment. Setting
an I/O hook forces Import to run in GOPATH mode, not invoking 'go list'.
This is undocumented, but it should be stable while GOPATH is
supported.

Heschi Kreinick 0511c4cc7a internal/imports: use ProcessEnv to filter files
In CL 247797 I accidentally used the default build.Context instead of
one generated from the ProcessEnv to match files. This has essentially
no effect because we only allow overriding GOROOT and GOPATH, but it's
still a mistake.

Danish Dua 75ebdcb73b gopls/internal/regtest: add expected ranges in completion tests
This change adds tests for package completion in multiline comments and package completion on a newline. It also adds expected ranges in completion tests since simply testing for returned item labels won't catch regression. For more info, see the discussion at https://go-review.googlesource.com/c/tools/+/253177.

Returning 'metBy' from expectations was not an ideal API, as extracting
the result value was cumbersome and error prone. It also forced quite a
bit of plumbing.

Using OnceMet, we can improve this by instead using a 'ReadDiagnostics'
expectation that reads diagnostics into a variable.

Rob Findley 6ec2cde963 internal/lsp/source: add some additional symbol downranking
Downrank symbols if they are:
 1. Unexported and outside of the workspace. Since one wouldn't jump to
    these symbols to e.g. view documentation, they are less relevant.
 2. Fields and interface methods. Usually one would jump to the type
    name, so having fields highly ranked can be noisy.

To facilitate this change and more generally clean up, symbolCollector
is refactored to pass around slices of *ast.Idents rather than build up
'.' separated names as it traverses nested nodes.

Heschi Kreinick 2db8f0ff89 internal/lsp/cache: fix -mod=mod for workspace module setups
When we're in workspace module mode, there may not be a go.mod at the
root of the workspace, so checking modURI != "" doesn't tell us whether
module mode is on. Add a flag to workspaceMode which is exactly that.

There are probably many more places that should be updated, but since
the design is in flux I don't want to cause more churn than necessary.
This is enough to unblock -mod=readonly by default.

(I missed this in CL 253799 because I was running the wrong Go Version.)
