Heschi Kreinick 9b8df07b91 internal/lsp: enable -mod=readonly in workspace module mode
Now that workspace module mode generates a combined go.sum there are
relatively few blockers to enabling -mod=readonly. Fix them and do it.

This CL is a bit of a grab bag, but the fixes are relatively separate. I
can split it into multiple CLs if desired.

- If module A depends on module B at v1.0.0, the go command will want to
upgrade the workspace module from v0.0.0-goplsworkspace to v1.0.0. To
prevent that, use vN.999999.0 as the base pseudoversion, adjusting v0 to
v1 where appropriate. A few test cases needed updating as a result.
- For old Go versions, sort the generated workspace module and
synthesize a go statement from the maximum go version declared in the
workspace.
- Some regtests need go.sum files created.
- matchErrorToModule created incorrect quick fixes: it would try to
download the top-level module mentioned in the error message, not the
one that actually caused the problem. Now it issues quick fixes for the
lowest-level module.
- TestMultiModuleModDiagnostics accidentally included the same module
in the workspace twice. Fix it, and make that an error.

Fixes golang/go#43346.

Go Tools

PkgGoDev

This subrepository holds the source for various packages and tools that support the Go programming language.

Some of the tools, godoc and vet for example, are included in binary Go distributions.

Others, including the Go guru and the test coverage tool, can be fetched with go get.

Packages include a type-checker for Go and an implementation of the Static Single Assignment form (SSA) representation for Go programs.

Download/Install

The easiest way to install is to run go get -u golang.org/x/tools/.... You can also manually git clone the repository to $GOPATH/src/golang.org/x/tools.

JS/CSS Formatting

This repository uses prettier to format JS and CSS files.

The version of prettier used is 1.18.2.

It is encouraged that all JS and CSS code be run through this before submitting a change. However, it is not a strict requirement enforced by CI.

Report Issues / Send Patches

This repository uses Gerrit for code changes. To learn how to submit changes to this repository, see https://golang.org/doc/contribute.html.

The main issue tracker for the tools repository is located at https://github.com/golang/go/issues. Prefix your issue with "x/tools/(your subdir):" in the subject line, so it is easy to find.
