Is there any way of showing which revision is equivalent to a certain tag?
If you want to know the revision number of what this tag points to you need to use svn log, which provides data in the format:
------------------------------------------------------------------------ r643 | [author] | [date] | [n] lines Added tag ------------------------------------------------------------------------ r643 | [author] | [date] | [n] lines [log message] ------------------------------------------------------------------------ ...
If you add the option --stop-on-copy
you can find out which revision the tag was created. Run svn log
both with and without the --stop-on-copy
option and the entry beneath the last one shown when run with the option will show the revision the tag ultimately points to.
Alternatively, assuming people aren't doing bad things in your repository (like committing against a tag) you can use svn info, it returns information in the format
Path: [path] URL: [url] Revision: [current repository revision] Node Kind: directory Schedule: normal Last Changed Author: [author] Last Changed Rev: [last revision this particular path was changed] Last Changed Date: YYYY-MM-DD hh:mm:ss TZ
You might call something like svn info http://www.example.com/svn/path/to/tag
Try this
svn log /path/to/tag -v --stop-on-copy
You might see something like this
r10 | user | 2010-02-07 17:06:01 -0800 (Sun, 07 Feb 2010) | 1 line Changed paths: A /path/to/tag (from /path/to/branch:5)
You can see that the tag was branched at revision 5
