Checkout question

[David Aldrich <Da...@EU.NEC.COM>]

Hi

Suppose I have a large project that has two directories A and B. Because the project is large, some users only checkout directory A:

svn co MyProject/A

Now suppose a user realises he need files from MyProject/B as well. Can he checkout B alongside A in the current working copy, or does he need to create a new working copy?

If it is possible, how can he do this?

Please assume SVN 1.4.6 for this scenario but if the solution will be easier in 1.5 please mention that as well.

Thanks

David

This:

	$ svn co MyProject/A

produces a directory called A which is a working copy anchored in that portion 
of the tree.

	$ svn co MyProject/B

produces a directory called B which is a working copy anchored in that portion 
of the tree.

Those two working copies are completely independent, and in fact totally 
ignorant of each other's presence.  They are not the same working copy, even 
though those folders are peers in the repository.  Through some trickery, it may 
be possible to join those two working copies together, but I don't feel 
comfortable advocating the machinations involved because it is more than a 
little hacky (and honestly, I'd have to try it myself to make sure I got it 
right).[1]

There will be a feature in 1.5.0 called "relative externals" where you could 
take some portion of B and embed it inside of A, without the distraction 
associated with ordinary externals (like not being able to commit changes in a 
single transaction to both the base URL and the external URL).  I don't know if 
this will help you or not.

For the present, the only good solution is to throw away the full A (and B) 
checkouts and do this instead:

	$ svn co MyProject

1) it involves the variously broken "non-recursive" checkout option...
