If a user is typing fast, they will quickly invalidate many snapshots. We don't want to stack up a bunch of stale type check and analysis operations, so we should propagate cancellation through the cache. Handles are long-lived, so we may cancel an operation only to restart it again later. Also, there may be multiple operations waiting on the same computation, and just because one is cancelled doesn't mean we should necessarily stop. The easiest way to support all that was to add an explicit state to each handle, and track the number of waiters. See the code for more details on Handle life cycles. As far as I can tell, the rest of gopls is prepared for this behavior. I added an explicit check to the type checking code, where I was worried it might get overly confused. But long-term it would probably be good to return an error from Get.

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.
