Michael I think svn log --limit 1 would work. It will give you the last log when the tag was modified. Since a tag should never be modified that log should refer to the copy That or svn log --stop-on-copy.

If no one has modified the tag, --limit 1 would yield the same results as --stop-on-copy. But if someone *has* modified the tag (which we agree shouldn't happen, but depending on your setup, it could - that's a whole other matter), that modification will appear instead of the copy which created the tag. If you use --stop-on-copy, you can detect this condition and the oldest log will end up being the creation of the tag. I think the best/easiest way is: svn log -r 1:HEAD --limit 1 --stop-on-copy $URL_TO_TAG (then parse the revision number out of that) The '-r 1:HEAD' reverses the order of log to return the entries from oldest to newest. Combining this with --stop-on-copy and --limit 1 gives you exactly the oldest log entry on that tag (which is the copy operation itself), whether or not it had changes after creation. This also works for branches (giving you the creation revision of the branch). -- Johan
the revision number and a tag
Hello, given a Subversion tag, what's the best way to get the revision number of that tag, i.e. the revision number with which the tag was created? Is it possible at all having checked out the tag to a local working copy? Or is there any other way to cross-reference a tag to a revision number? Thanks. Michael
