The size information of an avatar is not required during the import.
Check function 'import_uploads_local' and 'import_uploads_s3'
in 'export.py' for this.
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.
Change 'get_user_data' function to a more general function
to get data from the slack api using legacy tokens.
Also, change the error handling as upon invalid token,
the response is 200, but the response has an error
field in it.
For eg. Go to the following link with invalid token:
https://slack.com/api/emoji.list?token=xoxp-249056023425
Remove allocation ID function from slack import script. All the IDs
count will start from 0. Hence the ID List returned
by the allocation function is of no use, and we remove its implementation.
(example: get_total_messages_and_attachments function is of no use anymore,
hence we remove it)
The previous system would crash with some files (because for some
reason the comment count was 1 but there was no "initial comment") and
also the file comment and file name were sorta redundant.
The 'make_new_dir' bool value was used to create a new directory
every time True is passed. Now that avatars and uploads directory
are being created seperately, we don't need this anymore.
The domain name is being set in the helper function
'slack_workspace_to_realm', but it should be set in the main function
'do_convert_data', as we need it in other child functions of
'do_convert_data'.
The messages were first being read and passed to the helper
functions channel wise.
This function makes a list of all the messages in the all the channels
beforehand which would be used to pass in the helper functions.
slack avatar urls have the format:
'https://ca.slack-edge.com/<team_id>-<user_id>-<avatar_hash>-<size>'
For any url of this form, if the user hasn't uploaded an image,
Slack uses default gravatar, but we don't have a way of knowing if Slack
has used the uploaded image or the custom gravatar
eg: https://ca.slack-edge.com/T5YFFM2QY-U6006P1CN-gd41c3c33cbe-512.
Hence, avatar_source should be mapped to 'U'.
The check for the channel ('general' and 'random') must be added before
'build_defaultstream' function is called and then the id is incremented.
Otherwise, the id appended at the end of second defaultstream object, which would be
greater than the total number of defaultstream objects would crash at
'defaultstream_id_list[defaultstream_id]' which is a paramater of 'build_defaultstream'.
Added tests to prevent the same.
