This reflects the fact that these are just defensive programming (we
don't expect them to ever happen) and also nicely makes these lines
not show up in our missing test coverage reports.
Deletion of medium sized image is done if it exists before calling the
function 'ensure_medium_avatar_image', to avoid potentially confusing
problems with left-over medium-size avatar images from a previous run
being used when repeatedly importing the same realm in a development
environment..
Fixes#8949.
The comments explain this pretty well, but basically because we
rewrite the realm ID during the import process, we need to edit all
the message bodies that link to an attachment to instead link to the
post-processed URL where that file will be hosted on the new server.
Fixes#8926.
'processing_emojis' check is added in the 'import_uploads'
function, so that the emoji files present in the to be imported
data file can be uploaded.
The procedure of saving emoji files in slack importer is same as
saving attachments and avatars, and the import has the similar
procedure too.
In importing avatars, we use the implementation where the 'avatar_path'
is seperately calculated using realm and user ID and then the content
of the path provided in the avatar's 'records.json' are copied to this
'avatar_path'.
Similary, here for the uploads, 's3_file_name' is seperately calculated
using the realm ID and uploaded file name and then the content of the
path provided in upload's 'records.json' are copied to this 's3_file_name'.
'recipient_field' is added as a bool variable in the function
'update_id_map' to update the recipient foreign keys.
Recipient Foreign Key is equal to the UserProfile ID, if the
type is 1, and the same is equal to Stream ID, if the type is 2.
Hence a check is added in the 'update_id_map' field for this.
All the objects with realm ID as the foreign keys need to
be remapped with updated with the allocated ID.
Also the ID of the realm object itself is updated with the allocated
ID.
The 'id_field' bool variable is added to the function just to check
if the field is the ID of that object, and not the foreign key relation.
For foreign key field names, a "_id" has to be added after the field name,
however we don't need that for the ID field of the object.
During a slack import, we don't have medium-size avatars already
available in the export data set (and possibly also with a normal
import/export?). The medium size avatar can be created by the
'ensure_medium_avatar_image' function, which checks if the medium
image exists, and if it doesn't, it creates the image.
This commit was substantially edited by tabbott to get rid of an
undefined variable bug, avoid initializing the upload backend classes
in a loop, and add some TODO notes on things that could be improved
later.
This fixes some subtle JavaScript exceptions we've been getting in
zulipchat.com, caused by the system bot realm there not being "zulip"
interacting with get_cross_realm_users.
