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.
If any user had sent the reply to the welcome bot recommended by our
tutorial, then the Zulip export/import process didn't work properly,
because we weren't including (and then remapping) the recipient ID for
sending PMs to the cross-realm bots. This commit fixes that gap, by
recording the necessary data on the export side, and doing the
appropriate remapping on the import side.
The previous error messages for this were written for a tool only to
be used by a couple people, and didn't make clear what potential
causes were. Tweak these to provide greater clarity about what's
going on.
The main cause of these errors appearing in practice was fixed in
7ea5987e5d, but nothing strongly
prevents a similar issue from being introduced in the future.
Fixes#10078.
In records the IDs like the realm_id and user_profile_id
of 'records.json' should be integers. This was missing in the
S3 backend and this commit fixes that.
Added tests for this as well.
For the emojis, In 'records.json', the record should contain
the attribute 'file_name', which was missing in the S3 backend.
This commit adds this attribute, as well as tests for the
records of uploads, avatars and emojis in both local and S3 backend.
This should help make it explicit whenever we add a new table to Zulip
that we need to correctly categorize it for whether it will be
included in the data export, or not.
Export of RealmEmoji should also include the image
file of those emojis.
Here, we export emojis both for local and S3 backend
in a method with is similar to attachments and avatars.
Added tests for the same.
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.
