standard footers meanwhile go the "contact status",
so they are no longer a reason to trigger "full message view".
this was already discussed when the HTML view was introduced at #2125
however, forgotten to change when the "contact status" was added at #2218
this pr will result in a cleaner chat view
with less "Show Full Message..." buttons
and will also save some storage
(in fact, i came over that when reviewing #4129 )
IIRC, this was written this way back when we didn't have config caching,
in order to save database accesses by getting the config outside the
for loop.
get_chat_msgs() function is split into new get_chat_msgs() without flags
and get_chat_msgs_ex() which accepts booleans instead of bitflags.
FFI call dc_get_chat_msgs() is still using bitflags for compatibility.
JSON-RPC calls get_message_ids() and get_message_list_items()
accept booleans instead of bitflags now.
This allows to distinguish exceptions,
such as database errors, from invalid user input.
For example, if the From: field of the message
does not look like an email address, the mail
should be ignored. But if there is a database
failure while writing a new contact for the address,
this error should be bubbled up.
Services like Lacre [1] on Disroot and Inbound Encryption on Posteo [2]
offer to encrypt all incoming messages with the provided OpenPGP
public key. Resulting messages are encrypted, but not end-to-end encrypted
and not signed by the sender, therefore should not have a padlock displayed.
However, such encrypted and unsigned message is also not an indication
of an error on ongoing attack, so we shoud not report this as a problem
to the user.
