internal/lsp: attempt to make TestDebouncer more robust

CL 309276 added logic to retry TestDebouncer if its execution was
determined to be invalid.

Unfortunately it also reduced the delay period, which increases the
likelihood of a flake on any individual execution. This appears to have
more than offset any robustness resulting from the retries.

This CL does a few things to try to improve the test:
 - Remove t.Parallel: we want goroutines to be scheduled quickly.
 - Increase the debouncing delay.
 - Improve the logic for determining if a test was invalid.
 - Guard the valid variable with a mutex, since this was actually racy.

For golang/go#45085

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.
