# frozen_string_literal: true #-- # Some versions of the Bundler 1.1 RC series introduced corrupted # lockfiles. There were two major problems: # # * multiple copies of the same GIT section appeared in the lockfile # * when this happened, those sections got multiple copies of gems # in those sections. # # As a result, Bundler 1.1 contains code that fixes the earlier # corruption. We will remove this fix-up code in Bundler 1.2. module Bundler class LockfileParser attr_reader :sources, :dependencies, :specs, :platforms, :bundler_version, :ruby_version BUNDLED = "BUNDLED WITH".freeze DEPENDENCIES = "DEPENDENCIES".freeze PLATFORMS = "PLATFORMS".freeze RUBY = "RUBY VERSION".freeze GIT = "GIT".freeze GEM = "GEM".freeze PATH = "PATH".freeze PLUGIN = "PLUGIN SOURCE".freeze SPECS = " specs:".freeze OPTIONS = /^ ([a-z]+): (.*)$/i.freeze SOURCE = [GIT, GEM, PATH, PLUGIN].freeze SECTIONS_BY_VERSION_INTRODUCED = { Gem::Version.create("1.0") => [DEPENDENCIES, PLATFORMS, GIT, GEM, PATH].freeze, Gem::Version.create("1.10") => [BUNDLED].freeze, Gem::Version.create("1.12") => [RUBY].freeze, Gem::Version.create("1.13") => [PLUGIN].freeze, }.freeze KNOWN_SECTIONS = SECTIONS_BY_VERSION_INTRODUCED.values.flatten.freeze ENVIRONMENT_VERSION_SECTIONS = [BUNDLED, RUBY].freeze def self.sections_in_lockfile(lockfile_contents) lockfile_contents.scan(/^\w[\w ]*$/).uniq end def self.unknown_sections_in_lockfile(lockfile_contents) sections_in_lockfile(lockfile_contents) - KNOWN_SECTIONS end def self.sections_to_ignore(base_version = nil) base_version &&= base_version.release base_version ||= Gem::Version.create("1.0".dup) attributes = [] SECTIONS_BY_VERSION_INTRODUCED.each do |version, introduced| next if version <= base_version attributes += introduced end attributes end def initialize(lockfile) @platforms = [] @sources = [] @dependencies = {} @state = nil @specs = {} @rubygems_aggregate = Source::Rubygems.new if lockfile.match(/<<<<<<<|=======|>>>>>>>|\|\|\|\|\|\|\|/) raise LockfileError, "Your #{Bundler.default_lockfile.relative_path_from(SharedHelpers.pwd)} contains merge conflicts.\n" \ "Run `git checkout HEAD -- #{Bundler.default_lockfile.relative_path_from(SharedHelpers.pwd)}` first to get a clean lock." end lockfile.split(/(?:\r?\n)+/).each do |line| if SOURCE.include?(line) @state = :source parse_source(line) elsif line == DEPENDENCIES @state = :dependency elsif line == PLATFORMS @state = :platform elsif line == RUBY @state = :ruby elsif line == BUNDLED @state = :bundled_with elsif line =~ /^[^\s]/ @state = nil elsif @state send("parse_#{@state}", line) end end @sources << @rubygems_aggregate unless Bundler.feature_flag.disable_multisource? @specs = @specs.values.sort_by(&:identifier) warn_for_outdated_bundler_version rescue ArgumentError => e Bundler.ui.debug(e) raise LockfileError, "Your lockfile is unreadable.
