If this is true, then it is a major differenece to how the OS implements
directories in our working copies, and thus how users perceive them. This
definitely deserves a section in the book. The "traditional" definition of
a file system directory is a list of its contents, for instance inodes in
Unix like systems.

Hmmm -- if you add file F to directory D and this results in repository
revision R, then "svn log -rHEAD:1 D" will show you that D was changed in
revision R. So from a user perspective, it seems that the list of entries
in a directory *is* versioned with the directory.

If my analysis above is correct, I would be much happier if the directory
needed to be up-to-date, and thus get the "out-of-date" error like I do for
regular file changes. Just for the more uniform semantics. I now understand
that this would probably cause problems for mixed-revision working copies.

Again, I think this area is in need of a little more focus in the book, or
perhaps a FAQ.

I would like to thank you all for an inspiring discussion. :-)

Best regards,
Niels
