How to check if remote repository contains tag?

问题

How do I check from the command-line whether a local tag mytag exists on a remote repository and is pointing to the same changeset?

I believe that I can solve this problem once I solve the following sub-problems:

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

回答1:

Based on the aforementioned sub-questions, I believe the following will work:

// 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})
