New Revision: 1096921
URL: http://svn.apache.org/viewvc?rev=1096921&view=rev
Log:
Remove the last bit of working copy obstruction detection from the repository
diff editor.
This patch makes the merge editor aware of the list of added directories to
allow dry run property merges to directories.
* subversion/libsvn_client/merge.c
(merge_cmd_baton_t): Add hashtable of merge added paths.
(dry_run_added_p): New function.
(perform_obstruction_check): Specialize handling of merge-added paths.
(merge_dir_props_changed): Don't perform actual prop merging for added
directories when doing a dry-run merge.
(merge_file_added,
merge_dir_added,
merge_dir_deleted,
merge_dir_closed): Don't set optional output arguments to their default.
* subversion/libsvn_client/repos_diff.c
(close_directory): When an obstruction is noticed, update the content state
and use updated notifications.
* subversion/tests/cmdline/merge_tree_conflict_tests.py
(tree_conflicts_merge_edit_onto_missing,
tree_conflicts_merge_del_onto_missing): Expect more skip notifications.
* subversion/tests/cmdline/tree_conflict_tests.py
(at_directory_external): Mark as XFail again. This change moves the failure
to where we step into the external for the first time. The merge code
detects this properly now, but wants to apply mergeinfo on the external
to notice that it wasn't merged. But it can't and shouldn't store this
information.
