Significantly tweaked by tabbott because:
* Argparse was already handling the early checks
* Splitting the bottom loop into two loops means we validate all the
input before trying to run actual import code on anything.
* The argparse documentation was confusing about whether the paths
should be files or directories.
We extract the entire operations of the management command to a
function create_if_missing_realm_internal_bots in the
zerver/lib/onboarding.py. The logic for determining if there are any realm
internal bots which have not been created is extracted to a function
missing_any_realm_internal_bots in actions.py.
We add conditional infinite sleep to this delivery job as a means to
handle case of multiple servers in service to a realm running this
job. In such a scenerio race conditions might arise leading to
multiple deliveries for same message. This way we try to match the
behaviour of what other jobs do in such a case.
Note: We should eventually do something to make such jobs work
while being running on multiple servers.
This should help avoid confusing error messages for anyone
accidentally running this twice.
In particular, this also makes it easier to run Zulip inside
Kubernetes, since one doesn't need to worry about duplicate calls.
This fixes exceptions when sending PMs in development (where we were
trying to connect to the localhost push bouncer, which we weren't
authorized for, but even if we were, it wouldn't work, since there's
no APNS/GCM certs).
At the same time, we also set and order of operations that ensures one
has the opportunity to adjust the server URL before submitting
anything to us.
When you're importing with --destroy-rebuild-database, we need to
check subdomain availability after we've cleared out the database;
otherwise, trying to reuse the same subdomain doesn't work.
This logging was apparently broken when sorting imports; it's a fairly
unique thing in our codebase that this would be a problem. Prevent
future regressions by adding this exception explicitly to the isort
configuration.
Issue #2088 asked for a wrapper to be created for
`create_stream_if_needed` (called `ensure_stream`) for the 25 times that
`create_stream_if_needed` is called and ignores whether the stream was
created. This commit replaces relevant occurences of
`create_stream_if_needed` with `ensure_stream`, including imports.
The changes weren't significant enough to add any tests or do any
additional manual testing.
The refactoring intended to make the API easier to use in most cases.
The majority of uses of `create_stream_if_needed` ignored the second
parameter.
Fixes: #2088.
We also delete a couple helper functions that were only used there.
This management command was primarily used before we had a UI for
creating outgoing webhook bots.
We no longer accept URLs while creating emoji; so this management
command was probably left out while migrating realm emoji
infrastructure to upload backend.
We could fix this to work properly today, but the command was
originally written in a context when Zulip didn't have a UI for
managing realm emoji at all. Now that we do have such a UI, it
doesn't have a compelling use case, and work on migrating the realm
emoji schema demonstrates that this does have a maintenance cost.
So, we simply remove this command.
The fresh imported data shows that the users emails are not included
in the data. However, the data received from the older method of slack
(which is using legacy tokens) contains the email data of the users.
This code duplicated the code in setup_realm_internal_bots, with some
added logic to avoid trying to create the same bot twice. That logic
was buggy so that it would never work at all -- it subtracted a set of
UserProfile objects from a set of email strings -- so it looked like
the command might blow up when run after the users already existed.
In fact, the buggy logic wasn't necessary, because the work the
command does after it is idempotent -- in particular `create_users`,
within its subroutine `bulk_create_users`, already filters out users
that already exist. So just cut the buggy stuff out, deduplicate the
rest with `setup_realm_internal_bots`, and document that invariant on
the latter.
While we're here, in the common case bail early without doing any
per-realm work in Python, since we're running this on every upgrade.
