gopls/internal/telemetry: log timestamp when test fails We observed a couple of test failures. My current hypothesis is that the bug is in how countertest.ReadCounter and countertest.ReadStackCounter read the data. They try to access the counter values by reading the contents of the mapped file on disk and parsing them with counter.Parse. They call 'file.rotate' before reading the files to ensure the file is mapped. However, if file.rotate ends up actually rotating the underlying file (due to crossing the UTC day boundary), the counter data may be flushed out and reset. As we are moving to 'week' instead of 'day' for file rotation, I don't know how frequently we will encounter this issue though if this was the root cause. Log the timestamp when the test fails, to evaluate the hypothesis.

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.
