New Revision: 931449
URL: http://svn.apache.org/viewvc?rev=931449&view=rev
Log:
Fix the inheritance handling for entry->copyfrom_*. The mapping code was
not properly considering the copyfrom data between "this" node and the
ancestor nodes.
This fixes merge_tests 34 and 134 (broken by r930162), but proceeds to
break diff_tests 41 and merge_tests 8. Two steps forward...
* subversion/libsvn_wc/entries.c:
(read_entries_new): rework the logic that analyzes copyfrom information
on "this" node and the ancestor nodes. it was not (properly)
considering that an ancestor may imply "this" node is part of a copy.
* subversion/tests/cmdline/switch_tests.py:
(tree_conflicts_on_switch_2_1): note that we fail because an (A)dd is
incorrectly reported as a (M)odify, due to issues in wc_db.
(test_list): mark the above as an XFail
* subversion/tests/cmdline/update_tests.py:
(tree_conflicts_on_update_2_1, tree_conflict_uc2_schedule_re_add): leave
comments about the breakage due to wc_db issues.
(test_list): mark the above two tests as XFail
