RE: SVN Tag / Branch question

I am sorry to re-visit this again.

Yes, we have cases where files (in the same path, i.e. trunk/docs) are intended for different releases. If as you say, we are doing something wrong, what's a better way to handle this?

In /trunk/docs:

Release_doc_1.5
Release_doc_1.6
Release_doc_1.7

"Do you have different files in the same path that apply to different releases? If so, I think you are doing something wrong. "

I think perhaps you have a misunderstanding of how subversion revisions work. A revision contains ALL of the files in the path no matter what previous rev they were last changed in. Do you have different files in the same path that apply to different releases? If so, I think you are doing something wrong.

For example, you should have...

readme_v1.txt and then make a readme_v2.txt for a new release. You should just modify the readme.txt file accordingly and let svn keep track of which rev of that file goes with which release of your product.

You should go and review Chapter 1 and 2 of the documentation. http://svnbook.red-bean.com/en/1.7/svn-book.html
