Re: Wish List for Subversion

Curious - how many reversion control systems have you used?

The only reason why tags are really necessary in CVS is because there is no
atomic changesets. In CVS its impossible to check out your files to a
consistent set unless you tag them.

In SVN that is not necessary since any given change number should
technically compile fine (if people donšt check in broken build). Project
management can map releases versions to releases to customer.

Another option is using the cheap branch faculity of SVN... Every time you
have an external release you create a new branch in /tags (or whereever...)
with a name like "v16may2003_draft_to_customer". You then have the
advantage of having a real branch. So you can patch and customize for the
customer on their release branch, and integrate it back to your mainline if

Hope this helps.
