Muir Manders e54115a062 internal/lsp: fix stuck diagnostic messages 
The "analyses" cache in lsp/cache.(*Package).GetActionGraph was not
getting cleared on errors. This could result in future calls to
GetActionGraph waiting on the "ready" channel indefinitely. This in
turn caused the goroutine in cacheAndDiagnose to block indefinitely
and never send the diagnostic results back.

Now we use a defer statement to always close the channel. If we did
not succeed, we also clear out the cache entry and set a "succeeded =
false" flag to signal waiters that they need to retry. If in the
future errors other than context.Canceled/Timeout are possible, this
retry behavior may need to be revisited.

Fixes golang/go#30786

Go Tools

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.
