Patch for error deleting newely added directory.

From: Mo DeJong <supermo_at_bayarea.net>
Date: 2001-09-18 02:20:17 CEST

Hi all.

In an earlier mail, I mentioned this bug:

% mkdir foo
% svn add foo
% svn remove foo
svn_error: #21026 : <Can't find an entry>
  No default entry in directory `foo'

This problem was showing up in the svn_wc__entries_write method but
it seems that svn_wc__entry_modify was really to blame. It would
call the fold_state_changes method which would notice the move
from added -> deleted and remove the SVN_WC_ENTRY_THIS_DIR
from the entries hashtable. That would blow up in svn_wc__entries_write.

My solution to this problem was to notice the case where the this_dir
entry was removed and make a call to svn_wc_remove_from_revision_control
for the directory that was being "unadded". I also had to check for this
case in svn_wc_delete to avoid an attempt to delete the parent's entry

Does this seem like a reasonable approach? It fixes the bug for me, but
I wanted to make sure it is "right".

        Fix problem deleting a directory that had been added but was
        not yet committed.

        * subversion/libsvn_wc/entries.c (svn_wc__entry_modify): Check
        for the special case of deleting a directory that has not been
        committed. Call the svn_wc_remove_from_revision_control function
        to delete the administrative subdir in this case.
        * subversion/libsvn_wc/adm_ops.c (svn_wc_delete,
        svn_wc_remove_from_revision_control): Check to see if the
        entry we just marked for deletion was removed in svn_wc_delete.
        Add empty parent dir check to svn_wc_remove_from_revision_control
        so that function accepts short path names.
