Re: svnlook changed - howto see all deleted files in pre-/post-commit hooks

Thanks Ryan and David for the info, that solved my problem.
(I inspect the tree in a post-commit in the previous revision where the
deleted files were still present.)

What I was wondering though: if I commit a delete and run any svn
command on the REV-1 version in the post-commit hook, is it guaranteed
that in the meantime no other commits were run, thus making REV-1 invalid?
Or in other words: pre-commit, commit and post-commit are atomic?

Thanks,
Jan

If you're calling this from a pre-commit hook, then the directory currently still exists in the repository and you can call it just like that, which will look at the HEAD of the repository. If we're in a post-commit hook, the directory has already been deleted from the HEAD, so you would need to look at the preceding revision ($REV - 1).
