Previously it was required that a directory path is provided to the import API.
Now it is possible to point directly to the .asc file containing a secret key.
This allows UI to present a file selection dialog to the user
and let select the file directly.
Selecting a directory is still supported for backwards compatibility.
Such a message may be assigned to a wrong chat (e.g. undecipherable group msgs often get assigned to
the 1:1 chat with the sender). Add `DownloadState::Undecipherable` so that messages referencing
undecipherable ones don't go to that wrong chat too. Also do not reply to not fully downloaded
messages. Before `Message.error` was checked for that purpose, but a message can be error for many
reasons.
Previously only one connection, the one used to change the key,
was working after passphrase change.
With this fix the whole pool of connections
is recreated on passphrase change, so there is no need
to reopen the database manually.
These constants are current defaults in `pgp` crate,
this change would prevent accidental change due to rPGP upgrade
and make it easier to change in a single place.
It can be not good for membership consistency if we missed a message adding a member, but improves
security because nobody can add themselves to a group from now on.
1:1 chat may be blocked while the contact is not
if 1:1 chat was created as a result of scanning
a verified group join QR code with the contact
as the inviter. In this case 1:1 chat is blocked to hide it
while the contact is unblocked.
- If we don't know the parent (=In-Reply-To) message, then completely recreate the group member list
(i.e. use the member list of the incoming message) (because we assume that we missed some messages
& have a wrong group state).
- If the message has a "Chat-Group-Member-Removed: member@example.com" header, then remove this
member.
- If the message has a "Chat-Group-Member-Added: member@example.com" header, then add this member.
That means:
- Remove checks for the presense of `ContactId::SELF` in the group. Thus all recipients of a message
take the same decision about group membership changes, no matter if they are in the group
currently. This fixes a situation when a recipient thinks it's not a member because it missed a
message about its addition before.
NOTE: But always recreate membership list if SELF has been added. The older versions of DC don't
always set "In-Reply-To" to the latest message they sent, but to the latest delivered message (so
it's a race), so we need this heuristic currently.
- Recreate the group member list if we don't know the parent (=In-Reply-To) message, even if the
sender isn't in the group as per our view, because we missed some messages and our view may be
stale.
The new message for which `parent_query()` is done may assume that it will be received in a context
affected by those messages, e.g. they could add new members to a group and the new message will
contain them in "To:". Anyway recipients must be prepared to orphaned references.
This is already the way `get_chatlist_entries` works.
`get_similar_chatlist_entries` is renamed into
`get_similar_chat_ids` because return values are not entries anymore.
I.e. exclude from the list the following chats as well:
- Read-only mailing lists.
- Chats we're not a member of.
But as for ProtectionBroken chats, we return them, as that may happen to a verified chat at any
time. It may be confusing if a chat that is normally in the list disappears suddenly. The UI need to
deal with that case anyway.
(cherry picked from commit 83ef25e7de)
If a message is unsigned or signed with an unknown key, `MimeMessage::was_encrypted()` returns
false. So, it mustn't be checked when deciding whether to look into
`MimeMessage::decoded_data`. Looking through git history one can see that it's just a wrong check
left in the code for historical reasons.
Other MUAs don't set add/remove headers, so the only way for them to re-add us to the group is to
add us to To/CC/wherever. Previously it worked only for other members that are still in the group so
that they properly handled our re-addition, but we didn't.
