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.
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'.
This should help prevent against bugs where we accidentally introduce
use of sudo somewhere in the production installer or upgrade code path
(these used to happen all the time), which doesn't work on production
systems that don't have sudo setup.
Apparently, a bug in my refactor in
5edbcb87fd meant that "King L" would end
up matching "King Hamlet", because we weren't requiring a match at the
start of the word for the last word of a multi-word query.
Thanks to Greg Price for the report.
When our code raises an exception and Django converts it to a 500
response (in django.core.handlers.exception.handle_uncaught_exception),
it attaches the request to the log record, and we use this in our
AdminNotifyHandler to include data like the user and the URL path
in the error email sent to admins.
On this line, when our code raises an exception but we've decided (in
`TagRequests`) to format any errors as JSON errors, we suppress the
exception so we have to generate the log record ourselves. Attach the
request here, just like Django does when we let it do the job.
This still isn't an awesome solution, in that there are lots of other
places where we call `logging.error` or `logging.exception` while
inside a request; this just covers one of them. This is one of the
most common, though, so it's a start.
This restructures this fairly complicated function to a much cleaner
implementation, with fewer unnecessary variables and a cleaner flow.
While we're at it, we document the function.
For "#word text" (and similar situations, like "@word text" and
":word text"), we should only show the autocomplete for entries
where word matches the full first word of something being
completed (and similarly for multi-word phrases).
Fixes#8279
models.py should only contain thin wrapper functions. Furthermore,
this move allows us to remove the circular imports. The two moved
functions are interdependent and are thus moved in one commit.
