Re: How costly if we are creating tags for every continuous build?

We use Hudson as our continuous build engine and create a tag for each
build. As Andy L stated, tags are cheap. They're fast (takes less than
a second to create) and take almost no disk space.

Although many sites don't create Subversion tags for each build, Our
developers and QA engineers prefer tagging because they know the
Hudson build number and not the Subversion repository revision number
that was used for the build.

The main problem with tagging for each build is that you will get
thousands of build tags and maybe a few dozen actual release tags.
That makes finding the release tag much harder to find a release tag
you may be looking for.

To get around this problem, instead of putting our tags directly under
the "tags" directory we use a tags/REL for release tags and a tags/DEV
for the build tags. That keeps all of our build tags out of the way of
our actual release tags.
