+  `dc_stop_ongoing_process()` anymore.

+  this affects `dc_get_chat_contacts()`, `dc_get_contacts()` and `dc_get_blocked_contacts()` #3562

+/// ## About authserv-ids
+///
+/// After having checked DKIM, our email server adds an Authentication-Results header.
+///
+/// Now, an attacker could just add an Authentication-Results header that says dkim=pass
+/// in order to make us think that DKIM was correct in their From-forged email.
+///
+/// In order to prevent this, each email server adds its authserv-id to the
+/// Authentication-Results header, e.g. Testrun's authserv-id is `testrun.org`, Gmail's
+/// is `mx.google.com`. When Testrun gets a mail delivered from outside, it will then
+/// remove any Authentication-Results headers whose authserv-id is also `testrun.org`.
+///
+/// We need to somehow find out the authserv-id(s) of our email server, so that
+/// we can use the Authentication-Results with the right authserv-id.
+///
+/// ## What this function does
+///
+/// When receiving an email, this function is called and updates the candidates for
+/// our server's authserv-id, i.e. what we think our server's authserv-id is.
+///
+/// Usually, every incoming email has Authentication-Results  with our server's
+/// authserv-id, so, the intersection of the existing authserv-ids and the incoming
+/// authserv-ids for our server's authserv-id is a good guess for our server's
+/// authserv-id. When this intersection is empty, we assume that the authserv-id has
+/// changed and start over with the new authserv-ids.
+///
+/// See [`handle_authres`].

+///
+/// # Examples
+///
+/// Creating a new unecrypted database:
+///
+/// ```
+/// # let rt = tokio::runtime::Runtime::new().unwrap();
+/// # rt.block_on(async move {
+/// use deltachat::context::ContextBuilder;
+///
+/// let dir = tempfile::tempdir().unwrap();

+///      .unwrap();
+/// drop(context);
+/// # });
+/// ```
+///
+/// To use an encrypted database provide a password.  If the database does not yet exist it

+///
+/// ```
+/// # let rt = tokio::runtime::Runtime::new().unwrap();

 //! ## How messages are deleted
 //!
-//! When the message is deleted locally, its contents is removed and
-//! it is moved to the trash chat. This database entry is then used to
-//! track the Message-ID and corresponding IMAP folder and UID until
-//! the message is deleted from the server. Vice versa, when device
-//! deletes the message from the server, it removes IMAP folder and
-//! UID information, but keeps the message contents. When database
-//! entry is both moved to trash chat and does not contain UID
-//! information, it is deleted from the database, leaving no trace of
-//! the message.
+//! When Delta Chat deletes the message locally, it moves the message
+//! to the trash chat and removes actual message contents. Messages in
+//! the trash chat are called "tombstones" and track the Message-ID to
+//! prevent accidental redownloading of the message from the server,
+//! e.g. in case of UID validity change.
+//!
+//! Vice versa, when Delta Chat deletes the message from the server,
+//! it removes IMAP folder and UID row from the `imap` table, but
+//! keeps the message in the `msgs` table.
+//!
+//! Delta Chat eventually removes tombstones from the `msgs` table,
+//! leaving no trace of the message, when it thinks there are no more
+//! copies of the message stored on the server, i.e. when there is no
+//! corresponding `imap` table entry. This is done in the
+//! `prune_tombstones()` procedure during housekeeping.

+//! # Reactions.
+//!
+//! Reactions are short messages consisting of emojis sent in reply to
+//! messages. Unlike normal messages which are added to the end of the chat,
+//! reactions are supposed to be displayed near the original messages.
+//!
+//! RFC 9078 specifies how reactions are transmitted in MIME messages.
+//!
+//! Reaction update semantics is not well-defined in RFC 9078, so
+//! Delta Chat uses the same semantics as in
+//! [XEP-0444](https://xmpp.org/extensions/xep-0444.html) section
+//! "3.2 Updating reactions to a message". Received reactions override
+//! all previously received reactions from the same user and it is
+//! possible to remove all reactions by sending an empty string as a reaction,
+//! even though RFC 9078 requires at least one emoji to be sent.
