Remove unused docker-doxygen Dockerfile.
Switch scripts/run-doxygen.sh from bash to sh.
Use docker.io/alpine image instead of unsupported hrektts/doxygen
It happened multiple times now that I wanted to quickly execute a test, but because of a warning that had become an error, it didn't execute.
This turns warnings into warnings again; our CI will fail if there is a warning, anyway (because of RUSTFLAGS: -Dwarnings)
* 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()
