SVN find revision of tag

Is there any way of showing which revision is equivalent to a certain tag开发者_如何学运维?

---

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

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
