error!() will show the error directly to the user,
this is not useful in this case,
and also the message with the function-name is not for the end-user.
instead, the ui shall (and already does)
show some explaining text if dc_has_import() returns false;
the error!() is disturbing here as this results in two hints shown to the user.
this changes the behavior when scanning a setup-contact qr-code.
instead of waiting, until the whole protocol is finished,
which may take something between 10 seconds and several minutes,
the dc_join_secure_join() returns instantly;
the uis typically show the created chat then.
the returned chat-id is the same than if we wait for the protocol to finish,
it is the opportunistic one-to-one chat-id, so no changes there.
all this works even when both devices are offline.
after dc_join_secure_join() returns, however,
the usual setup-contact continues. ux-wise, once the protocol finishes,
a system-info-messages is added to the chat (also unchanged),
this is directly visible, in the chat as well as in the chatlist.
while the prococol runs, the user can alredy send message to the chat,
or do other things in the app.
if the user scans a new qr-code while an existing protocol is not finished yet,
the old join will be aborted (however, of course, created chats are kept).
we could also allow multiple joins at the same time,
however, this would be much more effort that this little change
and i am not sure if it is worth the effort.
finally, if a verified-group shall be joined,
this is not possible instantly, this is not affected by this pr.
same for unverified-groups, however, this could maybe be improved,
but also here, not sure if it is worth the effort
(i think most scans are setup-contact scans)
oauth2 crashes in beta23
because we did not let Serde remove the quotes from a parsed JSON email-address.
for autoconfig, we try to get a well-known URL
containing the domain of the used address - with the quote that is
https://autoconfig.gmail.com"/mail/config-v1.1.xml?...
unfortunately, instead of just returning an error,
(the url does not exist anyway)
reqwest crashes on the attempt to get this URL.
the Serde-thing is not obvious to me:
while serde_json::Value.as_str() removes the quotes,
serde_json::Value.to_string() does not.
before a message is actually deleted,
we verify that server_folder+server_uid matches the Message-ID,
so that we do not delete the wrong message by accident.
the reason for that is that, to my knowledge, server_folder+server_uid
are not necessarily stable but Message-ID is.
anyway, this check was broken and set the server_uid to 0 in all cases -
where it should be set to 0 _only_ on mismatches.
this commit sets the subject of groups to the name of the group.
if the message is a reply in the group, also the prefix `Re:` is added.
the Chat: prefix is removed for groups,
also the Fwd: prefix, as it this would be expected to be set to the
group name of the forwarded message, which is not really compatible with the
rule "group-name = subject" (forwarded messages are detected by the body,
not by the subject)
in the very beginning, we allowed using the cmdline partly from the ui
via a special function; this made info!() handy.
however, this is long gone and no longer needed.
we change the name on the wire as the old Chat-Group-Image header
could not be used on random mails, it was the marker for a "Changed" message,
if we would keep this names, things will fail for exising installations
as messages are dropped and a "Group image changed" message is shown instead.
