Otherwise the "Show Full Message..." button appears somewhere in the middle of the multipart
message, e.g. after a text in the first message bubble, but before a text in the second
bubble. Moreover, if the second/n-th bubble's text is shortened (ends with "[...]"), the user should
scroll up to click on "Show Full Message..." which doesn't look reasonable. Scrolling down looks
more acceptable (e.g. if the first bubble's text is shortened in a multipart message).
I'd even suggest to show somehow that message bubbles belong to the same multipart message, e.g. add
"[↵]" to the text of all bubbles except the last one, but let's discuss this first.
- iroh-net -> iroh
- iroh-gossip uses hex by default, use base32 manually to keep backwards compat
- use the new `iroh::protocol::Router` to manage the gossip integration
A user reported to me that after they left a group, they were implicitly readded, but there's no any
readdition message, so currently it looks in the chat like leaving it has no effect, just new
messages continue to arrive. The readdition probably happened because some member didn't receive the
user's self-removal message, anyway, at least there must be a message that the user is readded, even
if it isn't known by whom.
`receive_imf() is only used in tests and the REPL, which enables the
"internals" feature. This PR marks it as such, so that it's clear not
only from the comment that this function is not used for anything else.
If a message partially downloaded before is already IMAP-seen upon a full download, it should be
updated to `InSeen`. OTOH if it's not IMAP-seen, but already `InNoticed` locally, its state should
be preserved. So we take the maximum of two states.
There were many cases in which "member added/removed" messages were added to chats even if they
actually do nothing because a member is already added or removed. But primarily this fixes a
scenario when Alice has several devices and shares an invite link somewhere, and both their devices
handle the SecureJoin and issue `ChatGroupMemberAdded` messages so all other members see a
duplicated group member addition.
This change adds support for receiving
Autocrypt header in the protected part of encrypted message.
Autocrypt header is now also allowed in mailing lists.
Previously Autocrypt header was rejected when
List-Post header was present,
but the check for the address being equal to the From: address
is sufficient.
New experimental `protect_autocrypt` config is disabled
by default because Delta Chat with reception
support should be released first on all platforms.
I.e. add the "Messages are guaranteed to be end-to-end encrypted from now on." message and mark the
chat as protected again because no user action is required in this case. There are a couple of
problems though:
- If the program crashes earlier than the protection is restored, the chat remains
protection-broken. But this problem already exists because `ChatId::set_protection()` is never
retried.
- If multiple old unverified messages are received, protection messages added in between don't
annihilate, so they clutter the chat.
Received messages shouldn't mingle with just sent ones and appear somewhere in the middle of the
chat, so we go after the newest non fresh message.
But if a received outgoing message is older than some `InSeen` message, better sort the received
message purely by timestamp (this is an heuristic in order not to break the Gmail-like case
simulated by `verified_chats::test_old_message_4()`). We could place the received message just
before that `InSeen` message, but anyway the user may not notice it.
At least this fixes outgoing messages sorting for shared accounts where messages from other devices
should be sorted the same way as incoming ones.
This should fix ad-hoc groups splitting when messages are fetched out of order from different
folders or otherwise reordered, or some messages are missing so that the messages reference chain is
broken, or a member was removed from the thread and readded later, etc. Even if this way two
different threads are merged, it looks acceptable, having many threads with the same name/subject
and members isn't a common use case.
The "Chat-Group-Member-Removed" header is added to ad-hoc group messages as well, so we should check
for its presense before creating an ad-hoc group as we do for DC-style groups.
Before, if the user deleted a message too quickly after sending, it was deleted only locally. The
fix is to remember for tombstones that the corresponding message should be deleted on the server
too.
Delta Chat -style groups have names w/o prefixes like "Re: " even if the user is added to an already
existing group, so let's remove prefixes from ad-hoc group names too. Usually it's not very
important that the group is a classic email thread existed before, this info just eats up screen
space. Also this way a group name is likely to preserve if the first message was missed.
SQLite search with `LIKE` is case-insensitive only for ASCII chars. To make it case-insensitive for
all messages, create a new column `msgs.txt_normalized` defaulting to `NULL` (so we do not bump up
the database size in a migration) and storing lowercased/normalized text there when the row is
created/updated. When doing a search, search over `IFNULL(txt_normalized, txt)`.
Before, if `Config::FetchExistingMsgs` is set, existing messages were received with the `InSeen`
state set, but for bots they must be `InFresh` and also `IncomingMsg` events should be emitted for
them so that they are processed by bots as it happens with new messages.
`!to_ids().is_empty()` check is needed in cases of 1:1 chat creation
because otherwise `to_id` is undefined,
but in case of outgoing group message without recipients
observed on a second device creating a group should be allowed.
