from current_parsed_root->original. If we do, and two repositories
have a module with the same name, nasty things could happen.
This is hard. Perhaps we should send the Argument commands
later in this procedure, after we've had a chance to notice
which directores we're using (after do_recursion has been
called once). This means a _lot_ of rewriting, however.
What we need to do for that to happen is descend the tree
and construct a list of directories which are checked out
from current_cvsroot. Now, we eliminate from the list all
of those directories which are immediate subdirectories of
another directory in the list. To say that the opposite
way, we keep the directories which are not immediate
subdirectories of any other in the list. Here's a picture:
a
/ \
B C
/ \
D e
/ \
F G
/ \
H I
The node in capitals are those directories which are
checked out from current_cvsroot. We want the list to
contain B, C, F, and G. D, H, and I are not included,
because their parents are also checked out from
current_cvsroot.
The algorithm should be:
1) construct a tree of all directory names where each
element contains a directory name and a flag which notes if
that directory is checked out from current_cvsroot
a0
/ \
B1 C1
/ \
D1 e0
/ \
F1 G1
/ \
H1 I1
2) Recursively descend the tree. For each node, recurse
before processing the node. If the flag is zero, do
nothing. If the flag is 1, check the node's parent. If
the parent's flag is one, change the current entry's flag
to zero.
a0
/ \
B1 C1
/ \
D0 e0
/ \
F1 G1
/ \
H0 I0
3) Walk the tree and spit out "Argument" commands to tell
the server which directories to munge.
Yuck. It's not clear this is worth spending time on, since
we might want to disable cvs commands entirely from
directories that do not have CVSADM files...
Anyways, the solution as it stands has modified server.c
(dirswitch) to create admin files [via server.c
(create_adm_p)] in all path elements for a client's
"Directory xxx" command, which forces the server to descend
and serve the files there. client.c (send_file_names) has
also been modified to send only those arguments which are
appropriate to current_parsed_root->original.
