If currently there are no multi-device bots, let's disable sync messages for bots at all. Another
option is to auto-disable sync messages when `Config::Bot` is set, so sync messages can be reenabled
if needed. But let's leave this option for the future.
Notification server uses APNS server
for heartbeat notifications,
so registering FCM tokens there
will result in failing to notify them
and unregistering them anyway.
It's possible that when rebasing a PR adding a migration a merge-conflict doesn't occur if another
migration was added in the target branch. Better to have at least runtime checks that the migration
version is correct. Looks like compile-time checks are not possible because Rust doesn't allow to
redefine constants, only vars.
Instead of constructing lists of protected,
unprotected and hidden headers,
construct a single list of headers
and then sort them into separate lists
based on the well-defined policy.
This also fixes the bug
where Subject was not present in the IMF header
for signed-only messages.
Closes#5713
we're always checking the configuration encrypted.
saying it is 'preferred' encrypted is misleading,
therfore, just remove it.
i do not think, it is worth saying that we do not query 'http',
this is clear from the source code.
moreover, fix two typos.
Looks like it has no sense to send any profile data (From/To names, self-status; self-avatar was
never sent even before) in MDNs, they aren't normal messages and aren't seen in a MUA. Better not to
reveal profile data to the network and even to contacts in MDNs and make them more lightweight.
Follow-up to b771311593. Since that commit names are not revealed in
verified chats, but during verification (i.e. SecureJoin) they are still sent unencrypted. Moreover,
all profile data mustn't be sent even encrypted before the contact verification, i.e. before
"v{c,g}-request-with-auth". That was done for the selfavatar in
304e902fce, now it's done for From/To names and the self-status as
well. Moreover, "v{c,g}-request" and "v{c,g}-auth-required" messages are deleted right after
processing, so other devices won't see the received profile data anyway.
Probably sync messages generated for a not yet configured account are useless because there are no
other devices yet. And even if this is not true, we don't want to depend on the order of setting
`Config::SyncMsgs` and other keys. Also w/o this the Python tests don't work if we start syncing
`Config::MvboxMove` because they don't expect that sync messages are sent while configuring
accounts.
NB: We don't restart IO from the synchronisation code, so `MvboxMove` isn't effective immediately if
`ConfiguredMvboxFolder` is unset, but only after a reconnect to IMAP.
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.
This is a way to prevent redownloading locally deleted messages. Otherwise if a message is deleted
quickly after sending and `bcc_self` is configured, the BCC copy is downloaded and appears as a new
message as it happens for messages sent from another device.
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.
Since commit c0a17df344
(PR https://github.com/deltachat/deltachat-core-rust/pull/3402)
`send_smtp_messages` returns an error
as soon as it encounters the first message it failed to send.
Since this worked like this for about 2 years
without any problems, there is no need to revert the change,
but outdated comment should be removed.
If a display name should be protected (i.e. opportunistically encrypted), only put the corresponding
address to the unprotected headers. We protect the From display name only for verified chats,
otherwise this would be incompatible with Thunderbird and K-9 who don't use display names from the
encrypted part. Still, we always protect To display names as compatibility seems less critical here.
When receiving a messge, overwrite the From display name but not the whole From field as that would
allow From forgery. For the To field we don't really care. Anyway as soon as we receive a message
from the user, the display name will be corrected.

Otherwise it's impossible to remove a member with missing key from a protected group. In the worst
case a removed member will be added back due to the group membership consistency algo.
The "I left the group" message can't be sent to a protected group if some member's key is missing,
in this case we should remain in the group. The problem should be fixed first, then the user may
retry to leave the group.
There was a comment in `fetch_existing_msgs()`: "Bots don't want those messages". If a bot doesn't
want this setting, why enable it? It's disabled by default anyway.
`IsChatmail` is set also by `inbox_fetch_idle()`, but it isn't called during `configure()`. Setting
`IsChatmail` from `inbox_fetch_idle()` is necessary to handle client/server upgrades, but
`IsChatmail` also should be available for the app after configuring an account, e.g. DC Android
needs it to know whether to ask the user to disable battery optimisations.
