# There's a bug with 'gclient sync -D' that gets hit when the location of a
# dependency checkout (in the DEPS file) is moved to a path that contains
# (in a directory fashion) its old path. E.g., when Blink is moved from
# Webkit/Source/ to Webkit/. When this happens, a 'gclient sync -D' will
# blow away Webkit/Source/ after the sync, since it is no longer in the
# DEPS file, leaving the Blink checkout missing a Source/ subdirectory.
# This bug also gets hit the other way around - E.g., if Blink moves from
# Webkit/ to Webkit/Source/.
# To work around this, we sync twice, so that any directories deleted by
# the first sync will be restored in the second.
# TODO(rcui): Remove this workaround when the bug is fixed in gclient, or
# replace with a more sophisticated solution that syncs twice only when any
# paths in the DEPS file cannot be found after initial sync.
