如何检查远程存储库是否包含标签？

Question

如何从命令行检查远程存储库中是否存在本地标记 mytag 并指向同一个变更集？

我相信只要解决以下子问题，我就能解决这个问题：

1. How do I find out which changeset added a tag?
2. How to find out whether a remote repository contains a changeset?

Answer 1

基于上述子问题，我相信以下方法会起作用：

// Get the changeset that the tag points to
def referenced = $(hg id -q -r ${tag})

// Get the changeset that added the tag
def addedTag = $(hg log -r children(${referenced}) --template {node})

// Check whether the remote repository contains the changeset
def tagFound = $(hg outgoing -r ${addedTag})
