If configured address is `Bob@example.net`,
but the message arrives adding `bob@example.net`,
Bob's device should still recognize it as addition of self
and fully recreate the group.
If the sender of the message in protected group chat
is not a member of the chat, mark the sender name with `~`
as we do it in non-protected chats and set the error
instead of replacing the whole message with
"Unknown sender for this chat. See 'info' for more details."
To send a message to a protected group this way
the sender needs to know the group ID
and sign the message with the current verified key.
Usually this is just a late message
delivered shortly after the user has left
the group or was removed from it.
Replacing the message with a single error text part
as done before this change makes it impossible
to access anything other than text, such as attached images.
Other devices should get the same chat name as the currently used device, i.e. the name a user sees
after renaming the chat. This fix is minor because `improve_single_line_input()` logic isn't going
to change often, but still, and also it simplifies the code.
This was introduced in https://github.com/deltachat/deltachat-core-rust/pull/4685
for internal use when looking up a chat based on In-Reply-To,
but actually affects the UIs as they should not display Download button
when the message is downloaded but cannot be decrypted.
If verified key for a contact is changed via securejoin,
gossip the keys in every group with this contact next time
we send a message there to let others learn new verified key
and let the contact who has resetup their device learn keys of others
in groups.
The returned error is unexpected and no UI I tested with stoped IO really handled it besides maybe displaying a toast.
(desktop and iOS don't handle it, deltatouch shows a toast)
This should not be shown to the user, it is only shown to the user if the UI has a bug, so that bug should be clearly visible.
Merge the code paths for verified and autocrypt key.
If both are changed, only one will be added.
Existing code path adds a message to all chats with the contact
rather than to 1:1 chat. If we later decide that
only 1:1 chat or only verified chats should be notified,
we can add a separate `verified_fingerprint_changed` flag.
Otherwise we will try to create an ad-hoc group
and failing because there are only two contacts
and then unblock a 1:1 chat just to assign
the message to trash in the end.
Hidden 1:1 chat is created for the "chat protected" message.
It should not appear simply because we received
a read receipt from the contact in a group.
Looks like this doesn't fix anything currently, because a better message from
`apply_group_changes()` doesn't appear in a context with another better message, but why drop it if
it's possible to add it, moreover, messages about implicit member additions are never dropped while
looking less important.
The second SQL statement calculating chat size
was already fixed in f656cb29be,
but more important statement calculating member list intersection
was overlooked.
As a result, trash chat with members added there due to former bugs
could still appear in similar chats.
- Reduce cross-module dependencies.
- Stop bloating the `sync` module while implementing synchronisation of more entities.
- Now there's the only `ChatId` :)
An error while executing an item mustn't prevent next items from being executed. There was a comment
that only critical errors like db write failures must be reported upstack, but in fact it's hard to
achieve in the current design, there are no error codes or so, so it's bug-prone. E.g.
`ChatAction::Block` and `Unblock` already reported all errors upstack. So, let's make error handling
the same as everywhere and just ignore any errors in the item execution loop. In the worst case we
just do more unsuccessful db writes f.e.
It's sufficient if the local state is updated successfully, no need to fail the whole
operation. Anyway delivery of sync messages and applying them on other devices are beyond of our
control. If an error occurs when generating a sync messages, probably a log message is sufficient,
no need to even show it to a user. As for the tests, anyway there are ones on synchronisation which
perform necessary checks. Particularly, some sync messages can't be generated if an account is
unconfigured. Adding the corresponding checks to the device synchronisation code (and maybe even
more checks in the future) would complicate the code unnecessarily. Even errors caused by bugs in
this code aren't a reason to fail a local operation.
Sync chat contacts across devices for broadcast lists and groups. This needs the corresponding chat
to exist on other devices which is not the case for unpromoted groups, so it fails for them now but
it's only a warning and will work once creation of unpromoted groups is synchronised too.
