Re: Getting the high revision number

I stated in a reply to Andrew that I had lied to you all. Sorry 'bout
that. I was scanning files in the repository subtree for the 'Last
Changed Rev:' tag, which allows me to use the highest revision number of
a subtree as the build revision number for that subtree.

Given this new information, do you see anything wrong with what I'm
doing? I appreciate the insight you've already provided.

Thanks again,

Why random?
The working copy revision number is what he has checked out, which is
he will use as build number and as code to build from.
If the working copy has no local modifications, that number is exactly

what he needs.
If he checks out a fresh working copy, he's fine as well.

Why not use svnversion, maybe in combination with a regex to just get
of the numbers?

Most compilers I know of want to create object files....

Also, if the build is automated, there should always be only one build

Even if you do, the revision number can be fine if you say it's for the

foo product because you will always know the root of the foo project.

One could include tags or branch names, though, even if only for
purposes ("beta 2").

Which is somewhat unlikely, but that's what svnversion is for.
