Hi,
I narrowed down the change to this commit, in version 1.8.0-dev:
------------------------------------------------------------------------
r1441043 | rhuijben | 2013-01-31 08:20:25 -0800 (Thu, 31 Jan 2013) |
30 lines
Following up on r1440966, also handle file obstruction handling in the merge
from the file_openened function.
* subversion/libsvn_client/merge.c
(merge_file_baton_t): Add fields to store conflicts and skips.
(mark_dir_edited): Add comment.
(mark_file_edited): Handle skips and tree conflicts on files.
(merge_file_opened): Handle obstruction handling for changes, adds, deletes
and persist the result in the baton. Or notify if we know the result for
delete/add.
(merge_file_changed,
merge_file_added,
merge_file_deleted): Replace obstruction check with simple baton readout.
(merge_dir_opened): Tweak comment.
* subversion/tests/cmdline/merge_authz_tests.py
(mergeinfo_and_skipped_paths): Expect detailed skip.
* subversion/tests/cmdline/merge_tests.py
(merge_to_sparse_directories): Expect detailed skip.
* subversion/tests/cmdline/merge_tree_conflict_tests.py
(tree_conflicts_merge_edit_onto_missing): Expect detailed skip.
* subversion/tests/cmdline/tree_conflict_tests.py
(at_directory_external): Remove Wimp marker (added in r1440966)
I don't know Subversion internals so I haven't dug in further than
this. Is there a way that I should be resolving the tree conflict
that would tell Subversion that I don't want the subdirectory to have
a detached svn:mergeinfo? I'm using "svn resolve --accept=working
<path>" but that leaves the property in place on the file within path.
Lack of understanding this issue is preventing us from moving past
1.7; any help would be most appreciated.
Thank you,
--Pete
