Write to a tempfile then move, so that if the process dies mid-write it doesn't corrupt the store. Also improve error messaging so that if a file does get corrupted, the user has some hope of figuring out which file is broken. For background, see: docker/for-win#13180 docker/for-win#12561 For a repro case, see: https://github.com/nicks/contextstore-sandbox Signed-off-by: Nick Santos <nick.santos@docker.com> (cherry picked from commit c2487c2) Signed-off-by: Sebastiaan van Stijn <github@gone.nl>
