+Subject: [PATCH] rsync_remote: Fix a problem when receiving read-only
+ directories.
+
+Before this change, when the source directories hierarchy was
+read-only, the read-only mode would be preserved at the destination,
+preventing child directories to be recreated by a normal user (a
+permission denied error, EACCES would be raised).
+
+* execnet/rsync_remote.py (serve_rsync.receive_directory_structure):
+Bitwise OR to ensure the write bit is set on received directories.
+* testing/test_rsync.py (TestRSync)
+<test_read_only_directories>: New test.
