Today I did an
"svn st -uvn subversion" and was a bit surprised:
[mitch@deneb svn]$ svn st -uvn subversion
_ 294 subversion
_ 294 subversion/LICENSE
_ 294 subversion/svn-dev.el
_ 294 subversion/svn-dev.sh
Head revision: 311
my surprise was that all the directories were omitted in the status output.
I think this is wrong. it should show all the directory entries as well.
I spoke to Kevin at length about it on #svn, and found out that it was a direct
consequence of how svn handles non-recursion now (see quoted message).
I believe that this whole issue can be handled with the depth thingy, but
with the addition that a given depth should apply to directory entries as well, not just files, just as if it were a '-maxdepth' parameter to find, like this:
[mitch@deneb svn]$ find doc -maxdepth 0
[mitch@deneb svn]$ find doc -maxdepth 1
and DEPTH=infinity is plain
[mitch@deneb svn]$ find doc
(note that doc/programmer and doc/user are dirents)
of course, all the subcommands should work like this, so
$ svn up --depth=0 target_dir
should update the props of target_dir only
$ svn up --depth=1 target_dir
should update the props of target_dir, the file contents/props in target_dir
and all the props of all the immediate child-dirents of target_dir
$ svn up target_dir does the usual thing (full recursion)
I know some people are unconfortable with the --depth=1 case, 'cos it
doesn't fit well with the current implementation (dir props are not
stored in the parent, but in the dir's own .svn area), but I hope this
analogy will help:
given the above semantics, "svn up --depth=1 target_dir" is equivalent to
"svn up --depth=0 target_dir target_dir/*"
now think of "chown a+r target_dir target_dir/*":
it's the same as "svn up --depth=1 target_dir", and the chown _does_
change the props on dirents as well.
hm... what I really wanted to say is: no matter if --depth=0 or
--depth=1 is the "default non-recursive" behavior, but let it not be
something like "--depth=1.5" which excludes directories but not file
[btw, I think the default non recursive flag should mean --depth=1, but
we still need --depth=0 sometimes... probly -n should be --depth=1 and
-N be --depth=0, but this is not the main point of this mail]
waiting for comments,
