Overview

This package consists of a set of packages that are responsible for executing a particular command/feature/operation. The full list of features can be viewed here. The commands implement the common interface:

type Command interface {
	Execute(ctx context.Context) error
}

A command is executed by running the Execute method. The execution logic mostly shares the common pattern:

• Parse the arguments and validate them.
• Communicate with GitLab Rails using gitlabnet package. For example, it can be checking whether a client is authorized to execute this particular command or asking for a personal access token in order to return it to the client.
• If a command is related to Git operations, establish a connection with Gitaly using handler and gitaly packages and provide two-way communication between Gitaly and the client.
• Return results to the client.

This package is being used to build a particular command based on the passed arguments in the following files that are under cmd directory:

• cmd/gitlab-shell/command
• cmd/check/command
• cmd/gitlab-shell-authorized-keys-check/command
• cmd/gitlab-shell-authorized-principals-check/command

Functions

func CheckForVersionFlag

func CheckForVersionFlag(osArgs []string, version, buildTime string)

func Setup

func Setup(serviceName string, config *config.Config) (context.Context, func())

Setup() initializes tracing from the configuration file and generates a background context from which all other contexts in the process should derive from, as it has a service name and initial correlation ID set.
