-- alleviate login problems with providers which only

-
-- introduce per-contact profile images to send out 
-  own profile image heuristically, and fix sending
-  out of profile images in "in-prepare" groups. 
-  this also extends the Chat-spec that is maintained
-  in core to specify Chat-Group-Image and Chat-Group-Avatar
-  headers. thanks @r10s and @hpk42.
-
-- fix merging of protected headers from the encrypted
-  to the unencrypted parts, now not happening recursively
-  anymore.  thanks @hpk and @r10s
-
-- fix/optimize autocrypt gossip headers to only get 
-  sent when there are more than 2 people in a chat. 
-  thanks @link2xt
-
-- fix displayname to use the authenticated name 
-  when available (displayname as coming from contacts 
-  themselves). thanks @simon-laux
-
-- introduce preliminary support for offline autoconfig 
-  for nauta provider. thanks @hpk42 @r10s

-  if we cannot terminate the IDLE IMAP protocol. @hpk42 @link2xt
-
-- fix incoming multipart/mixed containing html, to show up as
-  attachments again.  Fixes usage for simplebot which sends html
-  files for users to interact with the bot. @adbenitez @hpk42 
-
-- refinements to internal autocrypt-handling code, do not send
-  prefer-encrypt=nopreference as it is the default if no attribute
-  is present.  @linkxt 
-
-- simplify, modularize and rustify several parts 
-  of dc-core (general WIP). @link2xt @flub @hpk42 @r10s

-Problem: missing eventual group consistency
---------------------------------------------
-
-If group members are concurrently adding new members,
-the new members will miss each other's additions, example:
-
-- Alice and Bob are in a two-member group
-
-- Alice adds Carol, concurrently Bob adds Doris
-
-- Carol will see a three-member group (Alice, Bob, Carol),
-  Doris will see a different three-member group (Alice, Bob, Doris),
-  and only Alice and Bob will have all four members.
-
-Note that for verified groups any mitigation mechanism likely
-needs to make all clients to know who originally added a member.
-
-
-solution: memorize+attach (possible encrypted) chat-meta mime messages
-----------------------------------------------------------------------
-
-For reference, please see https://github.com/deltachat/deltachat-core-rust/blob/master/spec.md#add-and-remove-members how MemberAdded/Removed messages are shaped.
-
-
-- All Chat-Group-Member-Added/Removed messages are recorded in their
-  full raw (signed and encrypted) mime-format in the DB
-
-- If an incoming member-add/member-delete messages has a member list
-  which is, apart from the added/removed member, not consistent
-  with our own view, broadcast a "Chat-Group-Member-Correction" message to
-  all members, attaching the original added/removed mime-message for all mismatching
-  contacts.  If we have no relevant add/del information, don't send a
-  correction message out.
-
-- Upong receiving added/removed attachments we don't do the
-  check_consistency+correction message dance.
-  This avoids recursion problems and hard-to-reason-about chatter.
-
-Notes:
-
-- mechanism works for both encrypted and unencrypted add/del messages
-
-- we already have a "mime_headers" column in the DB for each incoming message.
-  We could extend it to also include the payload and store mime unconditionally
-  for member-added/removed messages.
-
-- multiple member-added/removed messages can be attached in a single
-  correction message
-
-- it is minimal on the number of overall messages to reach group consistency
-  (best-case: no extra messages, the ABCD case above: max two extra messages)
-
-- somewhat backward compatible: older clients will probably ignore
-  messages which are signed by someone who is not the outer From-address.
-
-- the correction-protocol also helps with dropped messages.  If a member
-  did not see a member-added/removed message, the next member add/removed
-  message in the group will likely heal group consistency for this member.
-
-- we can quite easily extend the mechanism to also provide the group-avatar or
-  other meta-information.
-
-Discussions of variants
-++++++++++++++++++++++++
-
-- instead of acting on MemberAdded/Removed message we could send
-  corrections for any received message that addresses inconsistent group members but
-  a) this would delay group-membership healing
-  b) could lead to a lot of members sending corrections
-
-- instead of broadcasting correction messages we could only send it to
-  the sender of the inconsistent member-added/removed message.
-  A receiver of such a correction message would then need to forward
-  the message to the members it thinks also have an inconsistent view.
-  This sounds complicated and error-prone.  Concretely, if Alice
-  receives Bob's "Member-added: Doris" message, then Alice
-  broadcasting the correction message with "Member-added: Carol"
-  would reach all four members, healing group consistency in one step.
-  If Bob meanwhile receives Alice's "Member-Added: Carol" message,
-  Bob would broadcast a correction message to all four members as well.
-  (Imagine a situation where Alice/Bob added Carol/Doris
-  while both being in an offline or bad-connection situation).
-
-
-solution2: repeat member-added/removed messages
----------------------------------------------------
-
-Introduce a new Chat-Group-Member-Changed header and deprecate Chat-Group-Member-Added/Removed
-but keep sending out the old headers until the new protocol is sufficiently deployed.
-
-The new Chat-Group-Member-Changed header contains a Time-to-Live number (TTL)
-which controls repetition of the signed "add/del e-mail address" payload.
-
-Example::
-
-    Chat-Group-Member-Changed: TTL add "somedisplayname" someone@example.org
-        owEBYQGe/pANAwACAY47A6J5t3LWAcsxYgBeTQypYWRkICJzb21lZGlzcGxheW5h

-        clKdskprY+4LY0EBwLD3SQ7dPkTITCRD
-        =P6GG
-
-TTL is set to "2" on an initial Chat-Group-Member-Changed add/del message.
-Receivers will apply the add/del change to the group-membership,
-decrease the TTL by 1, and if TTL>0 re-sent the header.
-
-The "add|del e-mail address" payload is pgp-signed and repeated verbatim.
-This allows to propagate, in a cryptographically secured way,
-who added a member. This is particularly important for allowing
-to show in verified groups who added a member (planned).
-
-Disadvantage to solution 1:
-
-- requires to specify encoding and precise rules for what/how is signed.
-
-- causes O(N^2) extra messages
-
-- Not easily extendable for other things (without introducing a new
-  header / encoding)

-simplify/streamline mark-seen/delete/move/send-mdn job handling
----------------------------------------------------------------
-
-Idea: Introduce a new "msgwork" sql table that looks very
-much like the jobs table but has a primary key "msgid"
-and no job id and no foreign-id anymore. This opens up
-bulk-processing by looking at the whole table and combining
-flag-setting to reduce imap-roundtrips and select-folder calls.
-
-Concretely, these IMAP jobs:
-
-    DeleteMsgOnImap
-    MarkseenMsgOnImap
-    MoveMsg
-
-Would be replaced by a few per-message columns in the new msgwork table:
-
-- needs_mark_seen: (bool) message shall be marked as seen on imap
-- needs_to_move: (bool) message should be moved to mvbox_folder
-- deletion_time: (target_time or 0) message shall be deleted at specified time
-- needs_send_mdn: (bool) MDN shall be sent
-
-The various places that currently add the (replaced) jobs
-would now add/modify the respective message record in the message-work table.
-
-Looking at a single message-work entry conceptually looks like this::
-
-    if msg.server_uid==0:
-        return RetryLater  # nothing can be done without server_uid
-
-    if msg.deletion_time > current_time:
-        imap.mark_delete(msg)  # might trigger early exit with a RetryLater/Failed
-        clear(needs_deletion)
-        clear(mark_seen)
-
-    if needs_mark_seen:
-        imap.mark_seen(msg)    # might trigger early exit with a RetryLater/Failed
-        clear(needs_mark_seen)
-
-    if needs_send_mdn:
-        schedule_smtp_send_mdn(msg)
-        clear(needs_send_mdn)
-
-    if any_flag_set():
-        retrylater
-    # remove msgwork entry from table
-
-
-Notes/Questions:
-
-- it's unclear how much we need per-message retry-time tracking/backoff
-
-- drafting bulk processing algo is useful before
-  going for the implementation, i.e. including select_folder calls etc.
-
-- maybe it's better to not have bools for the flags but
-
-  0 (no change)
-  1 (set the imap flag)
-  2 (clear the imap flag)
-
-  and design such that we can cover all imap flags.
-
-- It might not be neccessary to keep needs_send_mdn state in this table
-  if this can be decided rather when we succeed with mark_seen/mark_delete.

-Running tests
-=============
+Installing bindings from source
+===============================
 
-After successful binding installation you can install a few more
-Python packages before running the tests::
+If you can't use "binary" method above then you need to compile
+to core deltachat library::
+
+    git clone https://github.com/deltachat/deltachat-core-rust
+    cd deltachat-core-rust
+    cd python
+
+If you don't have one active, create and activate a python "virtualenv":
+
+    python virtualenv venv  # or python -m venv
+    source venv/bin/activate
+
+Afterwards ``which python`` tells you that it comes out of the "venv"
+directory that contains all python install artifacts. Let's first
+install test tools::
+
+    pip install pytest pytest-timeout pytest-rerunfailures requests
+
+then cargo-build and install the deltachat bindings::
+
+    python install_python_bindings.py
+
+The bindings will be installed in release mode but with debug symbols.
+The release mode is necessary because some tests generate RSA keys
+which is prohibitively slow in debug mode.
+
+After successful binding installation you can finally run the tests::
 
-    python -m pip install pytest pytest-xdist pytest-timeout pytest-rerunfailures requests
     pytest -v tests
 
-This will run all "offline" tests and skip all functional
-end-to-end tests that require accounts on real e-mail servers.
+.. note::
 
-.. _livetests:
-
-running "live" tests with temporary accounts
----------------------------------------------
-
-If you want to run live functional tests you can set ``DCC_NEW_TMP_EMAIL``::
-
-    export DCC_NEW_TMP_EMAIL=https://testrun.org/new_email?t=1h_4w4r8h7y9nmcdsy
-
-With this, pytest runs create ephemeral e-mail accounts on the http://testrun.org server.
-These accounts exists for one 1hour and then are removed completely.
-One hour is enough to invoke pytest and run all offline and online tests:
-
-    pytest
-
-    # or if you have installed pytest-xdist for parallel test execution
-    pytest -n6
-
-Each test run creates new accounts.
+    Some tests are sometimes failing/hanging because of
+    https://github.com/deltachat/deltachat-core-rust/issues/331
+    and
+    https://github.com/deltachat/deltachat-core-rust/issues/326
 
 
-.. _sourceinstall:
+running "live" tests (experimental)
+-----------------------------------
 
-Installing bindings from source (Updated: July 2020)
-=========================================================
+If you want to run "liveconfig" functional tests you can set
+``DCC_PY_LIVECONFIG`` to:
 
-Install Rust and Cargo first.
-The easiest is probably to use `rustup <https://rustup.rs/>`_.
+- a particular https-url that you can ask for from the delta
+  chat devs.
 
-Bootstrap Rust and Cargo by using rustup::
+- or the path of a file that contains two lines, each describing
+  via "addr=... mail_pw=..." a test account login that will
+  be used for the live tests.
 
-   curl https://sh.rustup.rs -sSf | sh
+With ``DCC_PY_LIVECONFIG`` set pytest invocations will use real
+e-mail accounts and run through all functional "liveconfig" tests.
 
-Then clone the deltachat-core-rust repo::
-
-   git clone https://github.com/deltachat/deltachat-core-rust
-   cd deltachat-core-rust
-
-To install the Delta Chat Python bindings make sure you have Python3 installed.
-E.g. on Debian-based systems `apt install python3 python3-pip
-python3-venv` should give you a usable python installation.
-
-Ensure you are in the deltachat-core-rust/python directory, create the
-virtual environment and activate it in your shell::
-
-   cd python
-   python3 -m venv venv  # or: virtualenv venv
-   source venv/bin/activate
-
-You should now be able to build the python bindings using the supplied script::
-
-   python install_python_bindings.py
-
-The core compilation and bindings building might take a while,
-depending on the speed of your machine.
-The bindings will be installed in release mode but with debug symbols.
-The release mode is currently necessary because some tests generate RSA keys
-which is prohibitively slow in non-release mode.

-
-## User locations
-
-To send the location of the sender,
-the app can attach a file with the name `location.kml`.
-The file can contain one or more locations.
-Apps that support location streaming will typically collect some location events
-and send them together in one file.
-As each location has an independent timestamp,
-the apps can show the location as a track.
-
-Note that the `addr` attribute inside the  `location.kml` file
-MUST match the users email-address.
-Otherwise, the file is discarded silently;
-this is to protect against getting wrong locations,
-eg. forwarded from a normal MUA.

-//! # Ephemeral messages
-//!
-//! Ephemeral messages are messages that have an Ephemeral-Timer
-//! header attached to them, which specifies time in seconds after
-//! which the message should be deleted both from the device and from
-//! the server. The timer is started when the message is marked as
-//! seen, which usually happens when its contents is displayed on
-//! device screen.
-//!
-//! Each chat, including 1:1, group chats and "saved messages" chat,
-//! has its own ephemeral timer setting, which is applied to all
-//! messages sent to the chat. The setting is synchronized to all the
-//! devices participating in the chat by applying the timer value from
-//! all received messages, including BCC-self ones, to the chat. This
-//! way the setting is eventually synchronized among all participants.
-//!
-//! When user changes ephemeral timer setting for the chat, a system
-//! message is automatically sent to update the setting for all
-//! participants. This allows changing the setting for a chat like any
-//! group chat setting, e.g. name and avatar, without the need to
-//! write an actual message.
-//!
-//! ## Device settings
-//!
-//! In addition to per-chat ephemeral message setting, each device has
-//! two global user-configured settings that complement per-chat
-//! settings: `delete_device_after` and `delete_server_after`. These
-//! settings are not synchronized among devices and apply to all
-//! messages known to the device, including messages sent or received
-//! before configuring the setting.
-//!
-//! `delete_device_after` configures the maximum time device is
-//! storing the messages locally. `delete_server_after` configures the
-//! time after which device will delete the messages it knows about
-//! from the server.
-//!
-//! ## 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 messages are deleted
-//!
-//! Local deletion happens when the chatlist or chat is loaded. A
-//! `MsgsChanged` event is emitted when a message deletion is due, to
-//! make UI reload displayed messages and cause actual deletion.
-//!
-//! Server deletion happens by generating IMAP deletion jobs based on
-//! the database entries which are expired either according to their
-//! ephemeral message timers or global `delete_server_after` setting.
