Rob Findley 88be01311a internal/jsonrpc2: fix races in cancellation 
We had a deadlock in cases where a request was cancelled (1) after being
written to the stream, but (2) before a response was received. This
resulted in the request ID being removed from the pending map while the
server has the request, after which point the server response would hang
in Conn.Run trying to send to a nil channel.

After fixing this nil send there was still a race: it was possible that
Conn.Run could get the pending request, and Conn.Call would select
ctx.Done before Conn.Run could send to the response channel, again
resulting in a blocking send. Fix this by adding a buffer to the
response channel.

The response channel management is also made less forgiving, because we
should be able to reason precisely about how many sends and receives
will occur:
 + Don't close the response channel after sending a response: there
   should only be one recipient.
 + Don't delete the ID from pending map twice: it should only be cleaned
   up by Conn.Call.

Cancellation tests in the lsprpc package are updated to exercise the
race conditions.

Fixes golang/go#37159

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.
