* ignore status/footer updates from mailinglist messages
mailinglist software often modified existing footers
or adds footers on their own.
therefore,therefore, these footers often do not reflect the status/footer set by the user.
* test status footers not updated from mailinglists
some mailinglists have their name in square brackets prepended to the subject.
we pick up that name and remove the square brackets,
as these do not look good as the chat name in delta chat.
if a mailing list has a sequence of square brackets, we use all of them
(this seems to be okayish, at least i do not know of any complains).
however, the removal of square brackets was not nice for sequences,
resulting in `ml topic] [sub topic`.
this pr removes the square brackets only for the first name
and leave the other ones as is.
* more flexible render_webxdc_status_update_object()
* delay webxdc updates when ratelimit is reached
* inject updates messages to the SMTP loop as needed
this avoids starting several tasks
and allows sending updates out after a restart of the app.
* use mutex to prevent race conditions in status updates
* check ratelimiter only before the sending loop; it won't change until messages are actually sent out
* fix typo
* prefer standard type declaration over turbofish syntax
* use UNIQUE and ON CONFLICT for query smtp_status_updates
* combine DELETE+SELECT to one atomic statement
* as all operations on smtp_status_updates are now atomic, a mutex is no longer needed
* test DELETE+RETURNING statement
* simplify calls to can_send()
* comment about ratelimit boolean in send_smtp_messages()
This makes quotes created by user display properly in other MUAs like
Thunderbird and not start with space in MUAs that don't support format=flowed.
To distinguish user-created quotes from top-quote inserted by Delta
Chat, a newline is inserted if there is no top-quote and the first
line starts with ">".
Nested quotes are not supported, e.g. line starting with "> >" will
start with ">" on the next line if wrapped.
* do not use ratelimiter for bots
i tried some other approaches as having optional ratelimiter
or handle `can_send()` for bots differently,
but all that results in _far_ more code and/or indirections -
esp. as the "bot" config can change and is also persisted -
and the ratelimiter is created
at a point where the database is not yet available ...
of course, all that could be refactored as well,
but this two-liner also does the job :)
* update CHANGELOG
This allows account manager to construct a single event channel and
inject it into all created contexts instead of aggregating events from
separate event emitters.
This makes sure that under normal circumstances the LoginParam struct
is always fully validated, ensure future use does not have to be
careful with this.
The brittle handling of `server_flags` is also abstraced away from
users of it and is now handled entirely internally, as the flags is
really only a boolean a lot of the flag parsing complexity is removed.
The OAuth2 flag is moved into the ServerLoginParam struct as it really
belongs in there.
