this is meant to help configuration event consumers (Python, UIs)
to not hang waiting for configuration outcomes.
One test case is added that fails on main.
This did not affect actual message deletion,
because select_expired_messages already takes timestamp_rcvd
into account and does not delete system messages
that say "Messages are end-to-end encrypted" too early.
So it is a minor bug as estimate_deletion_cnt
is meant to only roughly estimate the number of messages
to be deleted. Still, there were no tests before,
so now estimate_deletion_cnt is tested.
Address inside the KML is not used anywhere,
and we are moving away from "primary" relay notation (and thus also
identifying contacts by email address).

chatmail relays (filtermail) expect {vc,vg}-request
messages to be multipart/mixed with a single part.
Messages had this structure
before commit e0494b0b37
so we need to keep it for compatibility.
This is mostly a reaction in response to
https://blog.rust-lang.org/2026/08/20/supply-chain-attack-on-arrayref/
I don't know when exactly
`cargo clippy` and similar commands (check, build, run etc.)
may update dependencies
and it does not look like they actively pull
the package index and update yanked crates.
We also keep the lockfile updated all the time
by checking in CI.
Still, all commands better use --locked as a precaution.
Requests now register before testing for shutdown,
so either the reader loop or the caller answers them.
Also failed start() winds down its threads, ignoring a broken pipe on stdin.
`version_string` is meant to be displayed by UI, and comes from the
wire.
therefore, as a general precaution, ensure a string that is
regarded as a typical version string. all versions in scope are
currently v123.456.789-shortsuffix, where suffix is a-z and mostly
unused in production. that is the base. we can adapt if there is really
a need, but not for theoretical version strings. as we do not stop
processing, things are not bad even if we missed a valid usecase herr.
moreover, if `version_string` is empty, we skip the candidate - as we
cannot display something useful to the user. that little bit of care is
expected from relays :)
This replaces independent data structures
which allowed invalid state of having both the public keys
and the shared secret, or having a shared secret
but not encrypting the message because encryption_pubkeys
was None instead of Some(Vec::new()).
Creating QR code or sending a message will still fail
with a shorter error, but no info message will be created anymore.
Most users should have migrated the channels by recreating them by now.
This change is needed for moving loading of the shared secret
to earlier stages of message preparation,
otherwise mimefactory will have to create these info messages
when loading the message into memory.
"ex" means "used to be, but no longer is".
"ext" means "extended", which is the intended meaning.
"Ext" is more common not only in the Rust ecosystem but in general.
We already had several people (myself included) asking
what "ex" is supposed to mean.
To reproduce this commit, search and replace `_ex(?!\w)` -> `_ext`.
But don't change `list_transports_ex` because it's public API.
Unencrypted messages are no longer sent as multipart/mixed
with Message-ID header duplicated inside.
This was useful as non-standard protection
against servers that rewrite the Message-ID,
but now most messages are sent encrypted
and for them standard RFC 9788 header protection
works the same way.
it is outdated and incomplete, and always was experimental.
it is not in use in any UI but to get the name of the chat in Ubuntu
Touch, i created an issue for that at
https://codeberg.org/lk108/deltatouch/issues/305
moreover it is used for python bindings as get_summary(), not sure how
much that is in use,
we can leave the API for that for now, but we should not encourage
further usage of the API

> we aim to inform about updates for installations outside of any

> there is already a PR on android at
https://github.com/deltachat/deltachat-android/pull/4582, however, the
information about "update available" is a mockup there.
>
> in general, there are 3 ideas around about how to gather the "update
available" infomation - (1) checking a central url, (2) let contacts
provide information, (3) let relay provide information. on various
one-to-one discussions, outcome is that (3) is the most reasonable way
to go.
this PR is about reading update information via IMAP metadata from the
relay.
it is up to the UI to call `get_app_version()` at a reasonable time and
frequency, see comment in the code. when called, `get_app_version()`
iterates over all known profiles and relays and checks for version
information, returning the newest for the given scope.
we do not use an event, as that is tricky wrt changes - we do not know
if other relays report later a newer version. we also do not cache
anything, to prevent bad relays avoiding us to update permanently. also
it is easier :)
<details>
<summary>outdated notes and questions</summary>
- ~~it is up to the clients to get the needed information, we could let
core filter, but it seems easy enough the other way round, and may have
debug advantages, one can iterate etc.~~ EDIT: we now filter in core,
this also makes the jsonrpc part easier, see review comments
- when is IMAP METADATA actually read? when are they ready? is that
really the correct place? i am up to change that, but beware, this is
not really my expertise, so someone else may need to take over :)
EDIT: see below, IMAP METADATA is read on connection, before fetching
starts, usually fast enough
- relay part is missing. once the format is settled and discussed
shortly here, that should be done soon as well. but this is definitely
not my expertise and needed to be done by someone else :)
- key for IMAP METADATA is `/shared/vendor/deltachat/appversions` -
shall we continue use `deltachat` for compatibility or so? `chatmail`
seems to be more correct
EDIT: we stay with the current

There is currently no place to document up to date SQL schema.
New database is initialized with src/sql/tables.sql
and then updated by migrations,
So tracking down how some column is used requires grepping the code,
looking for a migration adding it and corresponding commits.

also core src/imap.rs retries connecting (2s with backoff) but direct_imap is only used in (CI) tests
and we can just keep trying every second until pytest timeout hits.
As we are using a dedicated CI relay instance, we don't need to be careful with creating test addresses.
But re-using test addresses in a test running in a single worker can leak events/messages which compromises test isolation.
Instead of encountering random flaky tests because let's just not cache addresses to maximize test isolation.
The chat is always going to be encrypted, this is enough.
We actually do mark the contact as verified,
but the meaning of this verification is unclear
and we don't even display it visibly in the chat anymore.
This value is not used for any logic
except the disappearing messages timer rollback prevention.
It is unlikely that non-chat clients
participate in chats with disappearing messages,
and the case was not tested anyway.
bail!() bubbles up the error until it lands in the device chat,
which is way over the top for a reaction that is filtered out by channel owner.
currently this happens, as arcance chat uses different default reactions.
in the future, this may happen even more often when we allow custom filters,
that may change over time.
Adds following stock strings:
- You were removed by %1$s.
- You were added by %1$s.
and implicit equivalents:
- You were removed.
- You were added.
