gopls/internal/lsp/fake: retry ephemeral errors when renaming on windows Investigation of renaming flakes revealed that renaming is known to be flaky on windows, and the go command has a robustio package that works around known flakes for certain IO operations on darwin and windows. Rather than duplicate this logic piecemeal, copy the entire robustio package to the gopls module, along with a script to sync it from GOROOT using go generate. Use this new package to de-flake renaming, and replace an existing workaround. The copy script got a little out of hand at the point where I needed to add +build constraints. Nevertheless, I've decided to keep it with the caveat that it may be removed if it proves too difficult to maintain. As is, it at least serves as documentation for how the sync was done.

This repository provides the golang.org/x/tools module, comprising various tools and packages mostly for static analysis of Go programs, some of which are listed below. Use the “Go reference” link above for more information about any package.
It also contains the golang.org/x/tools/gopls module, whose root package is a language-server protocol (LSP) server for Go. An LSP server analyses the source code of a project and responds to requests from a wide range of editors such as VSCode and Vim, allowing them to support IDE-like functionality.
Selected commands:
cmd/goimports formats a Go program like go fmt and additionally inserts import statements for any packages required by the file after it is edited.cmd/callgraph prints the call graph of a Go program.cmd/digraph is a utility for manipulating directed graphs in textual notation.cmd/stringer generates declarations (including a String method) for “enum” types.cmd/toolstash is a utility to simplify working with multiple versions of the Go toolchain.These commands may be fetched with a command such as go install golang.org/x/tools/cmd/goimports@latest.
Selected packages:
go/ssa provides a static single-assignment form (SSA) intermediate representation (IR) for Go programs, similar to a typical compiler, for use by analysis tools.
go/packages provides a simple interface for loading, parsing, and type checking a complete Go program from source code.
go/analysis provides a framework for modular static analysis of Go programs.
go/callgraph provides call graphs of Go programs using a variety of algorithms with different trade-offs.
go/ast/inspector provides an optimized means of traversing a Go parse tree for use in analysis tools.
go/cfg provides a simple control-flow graph (CFG) for a Go function.
go/expect reads Go source files used as test inputs and interprets special comments within them as queries or assertions for testing.
go/gcexportdata and go/gccgoexportdata read and write the binary files containing type information used by the standard and gccgo compilers.
go/types/objectpath provides a stable naming scheme for named entities (“objects”) in the go/types API.
Numerous other packages provide more esoteric functionality.
