bulk fetch query of UserPfrofile against which
user_ids are validated, instead of looping
over user_ids and fetchingeach UserPfrofile resulting
in O(n) queries.
We use a truncated SHA256 of the id and a server-side secret to make
emoji have non-guessable filenames, while also making collisions
unlikely.
We also adjust the Slack import to use the same SHA-based name,
instead of taking the same name as it had in Slack.
We thumbnail and serve emoji with the same format as they were
uploaded. However, we preserved the original extension, which might
mismatch with the provided content-type.
Limit the content-type to a subset which is both (a) an image format
we can thumbnail, and (b) a media format which is widely-enough
supported that we are willing to provide it to all browsers. This
prevents uploading a `.tiff` emoji, for instance.
Based on this limited content-type, we then reverse to find the
reasonable extension to use when storing it. This is particularly
important because the local file storage uses the file extension to
choose what content-type to re-serve the emoji as.
This does nothing for existing emoji, which may have odd or missing
file extensions.
Aside from updating the doc structure, this commit
also rephrases step 4 to make it read better. The
list of supported events in step 5 is also removed.
Part of #29592.
We use the already existing server level setting to only allow
settings to be set to system groups, not a named user defined
group as well, in production. But we allow to settings to be set
to any named or anonymous user group in tests and development server.
"can_mention_group" setting can be set to user defined groups
because some of the realms already do that in production.
The existing server level setting is also renamed to make it clear
that both user defined groups and anonymous groups are not allowed
if that setting is set to False.
This commit also changes the error message to be consistent for the
case when a setting cannot be set to user defined groups as per
server level and setting and when a particular setting cannot be set
to user defined groups due to the configuration of that particular
setting. For this we add a new class SystemGroupRequiredError in
exceptions.py so that we need not re-write the error message in
multiple places.
Besides "RE:" and "FWD:", "AW:" (from German "Antwort" for answer) is
another common prefix in email subjects. Let email_mirror automatically
remove it as well.
When using the sub-expression purely for filtering, and not for
accessing the value in the resultset, .alias() is potentially faster
since it does not pull the value in as well.
This commit adds an 'transaction.atomic' decorator to the
'add_subscriptions_backend' view thus making the db operations
within the view atomic and helps to avoid race between events sent.
In tests where we make POST requests to this view, we have
wrapped the API calls with a transaction.atomic() context
manager. It helps us with NOT rolling back the entire test
transaction due to error responses.
