Question

我希望能够在两个Grit::Commit对象之间进行分析，这是更新的对象。我的意思是，如果commit_A是commit_B的父母（或父母的父母等），那么commit_B是更新的。这假定commit_A和commit_B位于同一分支上。

我考虑使用Grit::Commit#date()，但我认为这将是不准确的。

有什么想法吗？

这是我最终实施的内容。请参阅注释以获得解释

性能很慢，但使用repo.git.rev_list（通过method_missing）时效果更差。

require 'grit'

module Grit

    class Commit

        # Returns true if any commits in +commits+ are decendants of calling commit. True
        # means that one or more commits in +commits+ are newer.
        def has_decendant_in? *commits 
            total_commits = commits.flatten
            raise ArgumentError "at least one commit required." if total_commits.empty?
            total_commits.each do |commit|
                return true if repo.commits_between(commit.id, id).empty?
            end
            return false
        end

        # Returns an Array of commits which tie for being the newest commits. Ties can
        # occur when commits are in different branches.
        def self.newest *commits
            oldest_commits = []
            total_commits = commits.flatten
            raise ArgumentError "at least one commit required." if total_commits.empty?
            (total_commits).each do |commit|
                if commit.has_decendant_in?(total_commits - [commit])
                    oldest_commits << commit 
                end
            end
            return total_commits - oldest_commits
        end

    end

end
