Because flag synchronization is stateless, it can be performed at any time as long as it's guaranteed to be performed after any change to a message's filename list. Take advantage of this to synchronize tags immediately after a filename is added or removed while the message is still frozen. With this change, filename removal is atomic and the unsynchronized window for filename add is very short. --- notmuch-new.c | 57 +++++++++++++++++---------------------------------------- 1 files changed, 17 insertions(+), 40 deletions(-)
