Steve Howell 51f74a7fd8 provision: Manage digests more rigorously. 
We now have two functions related to digests
for processes:

    is_digest_obsolete
    write_digest_file

In most cases we now **wait** to write the
digest file until after we've successfully
run a process with its new inputs.

In one place, for database migrations, we
continue to write the digest optimistically.
We'll want to fix this, but it requires a
little more code cleanup.

Here is the typical sequence of events:

    NEVER RUN -
        is_digest_obsolete returns True
        quickly (we don't compute a hash)

        write_digest_file does a write (duh)

    AFTER NO CHANGES -
        is_digest_obsolete returns False
        after reading one file for old
        hash and multiple files to compute
        hash

        most callers skip write_digest_file

        (no files are changed)

    AFTER SOME CHANGES -
        is_digest_obsolete returns False
        after doing full checks

        most callers call write_digest_file
        *after* running a process

README.md

This directory contains scripts that:

  • Generally do not require access to Django or the database (those are "management commands"), and thus are suitable to run operationally.

  • Are useful for managing a production deployment of Zulip (many are also used in a Zulip development environment, though development-only scripts live in tools/).
