gopls/internal/cache: share goimports state for GOMODCACHE When using the gopls daemon, or with the multi-View workspaces that will be increasingly common following golang/go#57979, there is a lot of redundant work performed scanning the module cache. This CL eliminates that redundancy, by moving module cache information into the cache.Cache shared by all Sessions and Views. There should be effectively no change in behavior for gopls resulting from this CL. In ModuleResolver.scan, we still require that module cache roots are scanned. However, we no longer invalidate this scan in ModuleResolver.ClearForNewScan: re-scanning the module cache is the responsibility of a new ScanModuleCache function, which is independently scheduled. To enable this separation of refresh logic, a new refreshTimer type is extracted to encapsulate the refresh logic.

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.
This repository uses Gerrit for code changes. To learn how to submit changes, see https://golang.org/doc/contribute.html.
