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.
In 'test_subs' we were making POST request to add
subscrption using 'self.api_post'.
This commit updates the code to use the test helper
function 'common_subscribe_to_streams' instead.
This prep commit will also help us to avoid adding
'transaction.atomic' context manager to these API calls
individually in the case of error response in the next commit.
Previously the bot sent bot commands whenever an undefined message
was sent by the user. This commit intends to fix the problem so that
the bot will only respond to the first message it does not understand
and not reply to any future undefined messages.
Fixes part of #30049.
The reply given by welcome bot when it does not understand a message,
sent by the user is changed, so that the bot is more clear to the user.
Fixes part of #30049.
The previous message that welcome bot sent with
the bot commands has been removed in order to be more
clear and concise to the user. Previously weclome bot
also sent bot commands in intial message, this commit
intends to remove those commands.
Fixes part of #30049.
