This is adds foreign keys to the corresponding Recipient object in the
UserProfile on Stream tables, a denormalization intended to improve
performance as this is a common query.
In the migration for setting the field correctly for existing users,
we do a direct SQL query (because Django 1.11 doesn't provide any good
method for doing it properly in bulk using the ORM.).
A consequence of this change to the model is that a bit of code needs
to be added to the functions responsible for creating new users (to
set the field after the Recipient object gets created). Fortunately,
there's only a few code paths for doing that.
Also an adjustment is needed in the import system - this introduces a
circular relation between Recipient and UserProfile. The field cannot be
set until the Recipient objects have been created, but UserProfiles need
to be created before their corresponding Recipients. We deal with this
by first importing UserProfiles same way as before, but we leave the
personal_recipient field uninitialized. After creating the Recipient
objects, we call a function to set the field for all the imported users
in bulk.
A similar change is made for managing Stream objects.
MigrationsTestCase is intentionally omitted from this, since migrations
tests are different in their nature and so whatever setUp()
ZulipTestCase may do in the future, MigrationsTestCase may not
necessarily want to replicate.
Previously, if you exported a Zulip organization and then re-imported
it, we'd end up renumbering the user IDs and all direct foreign key
references to them in the database, but not the data-user-id
references in mentions. Fix this by parsing the message content and
doing that renumbering.
(Because we import raw markdown, not HTML, from third-party tools,
these changes won't affect data import from slack etc.)
Fixes the high-priority part of #11293.
Sending PM from a hamlet(consented) to othello is a case
of sending message from a consented user to a non consented
user. This result in the generation of more than one message
files during realm export. To handle this case _export_realm
is updated.
This lets us handle directly in our tooling the user experience that
we document for exporting a realm with member consent (before, it
required unpleasant manual work).
Fixes a bug in import_realm where secondary attributes like message
visibility weren't being set, and also makes bugs like this less likely in
the future.
Also, putting the plan_type change at the end of import_realm, so that
future restrictions to LIMITED realms don't affect the import process.
When we create new ids for message rows, we
now sort the new ids by their corresponding
pub_date values in the rows.
This takes a sizable chunk of memory.
This feature only gets turned on if you
set sort_by_date to True in realm.json.
At some point as part of the process of supporting renumbering data,
we changed the structure of our file uploads to expect `path` to match
`s3_path`, with both having the relative path within the overall
hierarchy (including the realm ID). This change updates the more
rarely-used S3 export code path to use that model, fixing a crash when
messages reference an Attachment object with a rewritten path_id.
The 'last_modified' value in emoji records is
needed for uploading the file to the S3 backend.
We set the same in the function 'import_uploads_s3'.
We also have to remove the keyword 'last_modified'
while building the RealmEmoji dict, as it is not
a field which exists in RealmEmoji objects.
For importing huddles we have to have unique huddle hashes.
Huddle hashes are extracted from the list of users participating
in a huddle. So to extract these user ids, we first use huddle
id to getting the matching recipient, and then we use subscription
to get the user ids from the recipient id.
Added tests for the same (tests slightly tweaked by tabbott).
