-
-- 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
-
-## 1.0.0-beta.15
-
-- fix #994 attachment appeared doubled in chats (and where actually
-  downloaded after smtp-send). @hpk42
-
-## 1.0.0-beta.14
-
-- fix packaging issue with our rust-email fork, now we are tracking
-  master again there. hpk42
-
-## 1.0.0-beta.13
-
-- fix #976 -- unicode-issues in display-name of email addresses. @hpk42
-
-- fix #985 group add/remove member bugs resulting in broken groups.  @hpk42
-
-- fix hanging IMAP connections -- we now detect with a 15second timeout
-  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
-
-- use async-email/async-smtp to handle SMTP connections, might
-  fix connection/reconnection issues. @link2xt 
-
-- more tests and refinements for dealing with blobstorage @flub @hpk42 
-
-- use a dedicated build-server for CI testing of core PRs
-
-
-## 1.0.0-beta.12
-
-- fix python bindings to use core for copying attachments to blobdir
-  and fix core to actually do it. @hpk42
-
-## 1.0.0-beta.11
-
-- trigger reconnect more often on imap error states.  Should fix an 
-  issue observed when trying to empty a folder.  @hpk42
-
-- un-split qr tests: we fixed qr-securejoin protocol flakyness 
-  last weeks. @hpk42
-
-## 1.0.0-beta.10
-
-- fix grpid-determination from in-reply-to and references headers. @hpk42
-
-- only send Autocrypt-gossip headers on encrypted messages. @dignifiedquire
-
-- fix reply-to-encrypted message to also be encrypted. @hpk42
-
-- remove last unsafe code from dc_receive_imf :) @hpk42
-

-  can play with using it. @jikstra
-
-- fix encoding of subjects and attachment-filenames @hpk42
-  @dignifiedquire . 
-
-## 1.0.0-beta.9
-
-- historic: we now use the mailparse crate and lettre-email to generate mime
-  messages.  This got rid of mmime completely, the C2rust generated port of the libetpan 
-  mime-parse -- IOW 22KLocs of cumbersome code removed! see 
-  https://github.com/deltachat/deltachat-core-rust/pull/904#issuecomment-561163330
-  many thanks @dignifiedquire for making everybody's life easier 
-  and @jonhoo (from rust-imap fame) for suggesting to use the mailparse crate :) 
-
-- lots of improvements and better error handling in many rust modules 
-  thanks @link2xt @flub @r10s, @hpk42 and @dignifiedquire 
-
-- @r10s introduced a new device chat which has an initial
-  welcome message.  See 
-  https://c.delta.chat/classdc__context__t.html#a1a2aad98bd23c1d21ee42374e241f389
-  for the main new FFI-API.
-
-- fix moving self-sent messages, thanks @r10s, @flub, @hpk42
-
-- fix flakyness/sometimes-failing verified/join-protocols, 
-  thanks @flub, @r10s, @hpk42
-
-- fix reply-to-encrypted message to keep encryption 
-
-- new DC_EVENT_SECUREJOIN_MEMBER_ADDED event 
-
-- many little fixes and rustifications (@link2xt, @flub, @hpk42)
-
-
-## 1.0.0-beta.8
-
-- now uses async-email/async-imap as the new base 
-  which makes imap-idle interruptible and thus fixes
-  several issues around the imap thread being in zombie state . 
-  thanks @dignifiedquire, @hpk42 and @link2xt. 
-
-- fixes imap-protocol parsing bugs that lead to infinitely
-  repeated crashing while trying to receive messages with
-  a subjec that contained non-utf8. thanks @link2xt
-
-- fixed logic to find encryption subkey -- previously 
-  delta chat would use the primary key for encryption
-  (which works with RSA but not ECC). thanks @link2xt
-
-- introduce a new device chat where core and UIs can 
-  add "device" messages.  Android uses it for an initial
-  welcome message. thanks @r10s
-
-- fix time smearing (when two message are virtually send
-  in the same second, there would be misbehaviour because
-  we didn't persist smeared time). thanks @r10s
-
-- fix double-dotted extensions like .html.zip or .tar.gz  
-  to not mangle them when creating blobfiles.  thanks @flub
-
-- fix backup/exports where the wrong sql file would be modified,
-  leading to problems when exporting twice.  thanks @hpk42
-
-- several other little fixes and improvements 
-
-
-## 1.0.0-beta.7
-
-- fix location-streaming #782
-
-- fix display of messages that could not be decrypted #785
- 
-- fix smtp MAILER-DAEMON bug #786 
-
-- fix a logging of durations #783
-
-- add more error logging #779
-

 # Continuous Integration Scripts for Delta Chat
 
-Continuous Integration, run through CircleCI and an own build machine.
-
-## Description of scripts 
-
-- `../.circleci/config.yml` describing the build jobs that are run
-  by Circle-CI
-
-- `remote_tests_python.sh` rsyncs to a build machine and runs
-  `run-python-test.sh` remotely on the build machine. 
-
-- `remote_tests_rust.sh` rsyncs to the build machine and runs
-  `run-rust-test.sh` remotely on the build machine. 
-
-- `doxygen/Dockerfile` specifies an image that contains
-  the doxygen tool which is used by `run-doxygen.sh` 
-  to generate C-docs which are then uploaded 
-  via `ci_upload.sh` to `https://c.delta.chat/_unofficial_unreleased_docs/<BRANCH>`
-  (and the master branch is linked to https://c.delta.chat proper). 
+Continuous Integration is run through CircleCI
+but is largely independent of it. 
 
 
-## Triggering runs on the build machine locally (fast!)
+## Generating docker containers for performing build step work 
 
-There is experimental support for triggering a remote Python or Rust test run 
-from your local checkout/branch. You will need to be authorized to login to 
-the build machine (ask your friendly sysadmin on #deltachat freenode) to type::
+All tests, docs and wheel building is run in docker containers:
 
-    ci_scripts/manual_remote_tests.sh rust
-    ci_scripts/manual_remote_tests.sh python
+- **coredeps/Dockerfile** specifies an image that contains all 
+  of Delta Chat's core dependencies as linkable libraries. 
+  It also serves to run python tests and build wheels 
+  (binary packages for Python). 
 
-This will **rsync** your current checkout to the remote build machine 
-(no need to commit before) and then run either rust or python tests. 
+- **doxygen/Dockerfile** specifies an image that contains
+  the doxygen tool which is used to generate C-docs. 
 
-# Outdated files (for later re-use)
+To run tests locally you can pull existing images from "docker.io",
+the hub for sharing Docker images::
 
-`coredeps/Dockerfile` specifies an image that contains all 
-of Delta Chat's core dependencies. It used to run 
-python tests and build wheels (binary packages for Python)
+    docker pull deltachat/coredeps
+    docker pull deltachat/doxygen 
 
-You can build the docker images yourself locally
+or you can build the docker images yourself locally
 to avoid the relatively large download:: 
  
     cd ci_scripts  # where all CI things are 
     docker build -t deltachat/coredeps docker-coredeps
     docker build -t deltachat/doxygen docker-doxygen 
+
+## ci_run.sh (main entrypoint called by circle-ci)
+
+Once you have the docker images available 
+you can run python testing, documentation generation 
+and building binary wheels:: 
+
+    sh DOCS=1 TESTS=1 ci_scripts/ci_run.sh 
+    
+## ci_upload.sh (uploading artifacts on success) 
+
+- python docs to `https://py.delta.chat/_unofficial_unreleased_docs/<BRANCH>`
+
+- doxygen docs to `https://c.delta.chat/_unofficial_unreleased_docs/<BRANCH>`
+
+- python wheels to `https://m.devpi.net/dc/<BRANCH>`
+  so that you install fully self-contained wheels like this:
+  `pip install -U -i https://m.devpi.net/dc/<BRANCH> deltachat`

-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
-        bWUiIHNvbWVvbmVAZXhhbXBsZS5vcmcgCokBHAQAAQIABgUCXk0MqQAKCRCOOwOi
-        ebdy1hfRB/wJ74tgFQulicthcv9n+ZsqzwOtBKMEVIHqJCzzDB/Hg/2z8ogYoZNR
-        iUKKrv3Y1XuFvdKyOC+wC/unXAWKFHYzY6Tv6qDp6r+amt+ad+8Z02q53h9E55IP
-        FUBdq2rbS8hLGjQB+mVRowYrUACrOqGgNbXMZjQfuV7fSc7y813OsCQgi3tjstup
-        b+uduVzxCp3PChGhcZPs3iOGCnQvSB8VAaLGMWE2d7nTo/yMQ0Jx69x5qwfXogTk
-        mTt5rOJyrosbtf09TMKFzGgtqBcEqHLp3+mQpZQ+WHUKAbsRa8Jc9DOUOSKJ8SNM
-        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)

+   cross-claim or counterclaim in a lawsuit) alleging that the Work
+   or a Contribution incorporated within the Work constitutes direct
+   or contributory patent infringement, then any patent licenses
+   granted to You under this License for that Work shall terminate
+   as of the date such litigation is filed.
+
+4. Redistribution. You may reproduce and distribute copies of the
+   Work or Derivative Works thereof in any medium, with or without
+   modifications, and in Source or Object form, provided that You
+   meet the following conditions:
+
+   (a) You must give any other recipients of the Work or
+       Derivative Works a copy of this License; and

+   (c) You must retain, in the Source form of any Derivative Works
+       that You distribute, all copyright, patent, trademark, and
+       attribution notices from the Source form of the Work,
+       excluding those notices that do not pertain to any part of
+       the Derivative Works; and
+
+   (d) If the Work includes a "NOTICE" text file as part of its
+       distribution, then any Derivative Works that You distribute must
+       include a readable copy of the attribution notices contained
+       within such NOTICE file, excluding those notices that do not
+       pertain to any part of the Derivative Works, in at least one
+       of the following places: within a NOTICE text file distributed
+       as part of the Derivative Works; within the Source form or
+       documentation, if provided along with the Derivative Works; or,
+       within a display generated by the Derivative Works, if and
+       wherever such third-party notices normally appear. The contents
+       of the NOTICE file are for informational purposes only and
+       do not modify the License. You may add Your own attribution
+       notices within Derivative Works that You distribute, alongside
+       or as an addendum to the NOTICE text from the Work, provided
+       that such additional attribution notices cannot be construed
+       as modifying the License.
+
+   You may add Your own copyright statement to Your modifications and
+   may provide additional or different license terms and conditions
+   for use, reproduction, or distribution of Your modifications, or
+   for any such Derivative Works as a whole, provided Your use,
+   reproduction, and distribution of the Work otherwise complies with
+   the conditions stated in this License.
+
+5. Submission of Contributions. Unless You explicitly state otherwise,
+   any Contribution intentionally submitted for inclusion in the Work
+   by You to the Licensor shall be under the terms and conditions of
+   this License, without any additional terms or conditions.
+   Notwithstanding the above, nothing herein shall supersede or modify
+   the terms of any separate license agreement you may have executed
+   with Licensor regarding such Contributions.
+
+6. Trademarks. This License does not grant permission to use the trade
+   names, trademarks, service marks, or product names of the Licensor,
+   except as required for reasonable and customary use in describing the
+   origin of the Work and reproducing the content of the NOTICE file.

+7. Disclaimer of Warranty. Unless required by applicable law or
+   agreed to in writing, Licensor provides the Work (and each
+   Contributor provides its Contributions) on an "AS IS" BASIS,
+   WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+   implied, including, without limitation, any warranties or conditions
+   of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+   PARTICULAR PURPOSE. You are solely responsible for determining the
+   appropriateness of using or redistributing the Work and assume any
+   risks associated with Your exercise of permissions under this License.
+
+8. Limitation of Liability. In no event and under no legal theory,
+   whether in tort (including negligence), contract, or otherwise,
+   unless required by applicable law (such as deliberate and grossly
+   negligent acts) or agreed to in writing, shall any Contributor be
+   liable to You for damages, including any direct, indirect, special,
+   incidental, or consequential damages of any character arising as a
+   result of this License or out of the use or inability to use the
+   Work (including but not limited to damages for loss of goodwill,
+   work stoppage, computer failure or malfunction, or any and all
+   other commercial damages or losses), even if such Contributor
+   has been advised of the possibility of such damages.
+
+9. Accepting Warranty or Additional Liability. While redistributing
+   the Work or Derivative Works thereof, You may choose to offer,
+   and charge a fee for, acceptance of support, warranty, indemnity,
+   or other liability obligations and/or rights consistent with this
+   License. However, in accepting such obligations, You may act only
+   on Your own behalf and on Your sole responsibility, not on behalf
+   of any other Contributor, and only if You agree to indemnify,
+   defend, and hold each Contributor harmless for any liability
+   incurred by, or claims asserted against, such Contributor by reason
+   of your accepting any such warranty or additional liability.

@@ -3,98 +3,41 @@ deltachat python bindings
 =========================
 
 This package provides bindings to the deltachat-core_ Rust -library
-which implements IMAP/SMTP/MIME/PGP e-mail standards and offers
-a low-level Chat/Contact/Message API to user interfaces and bots.
+which provides imap/smtp/crypto handling as well as chat/group/messages
+handling to Android, Desktop and IO user interfaces.
 
+Installing pre-built packages (linux-only)
+==========================================
 
-Installing bindings from source (Updated: 20-Jan-2020)
-=========================================================
-
-Install Rust and Cargo first.  Deltachat needs a specific nightly
-version, the easiest is probably to first install Rust stable from
-rustup and then use this to install the correct nightly version.
-
-Bootstrap Rust and Cargo by using rustup::
-
-   curl https://sh.rustup.rs -sSf | sh
-
-Then GIT clone the deltachat-core-rust repo and get the actual
-rust- and cargo-toolchain needed by deltachat::
-
-   git clone https://github.com/deltachat/deltachat-core-rust
-   cd deltachat-core-rust
-   rustup show
-
-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::
-
-   ./install_python_bindings.py
-
-The installation might take a while, depending on 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.
-
-After successful binding installation you can install a few more
-Python packages before running the tests::
-
-    python -m pip install pytest pytest-timeout pytest-rerunfailures requests
-    pytest -v tests
-
-
-running "live" tests with temporary accounts
----------------------------------------------
-
-If you want to run "liveconfig" functional tests you can set
-``DCC_NEW_TMP_EMAIL`` to:
-
-- a particular https-url that you can ask for from the delta
-  chat devs. This is implemented on the server side via
-  the [mailadm](https://github.com/deltachat/mailadm) command line tool.
-
-- 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.
-
-With ``DCC_NEW_TMP_EMAIL`` set pytest invocations will use real
-e-mail accounts and run through all functional "liveconfig" tests.
-
-
-Installing pre-built packages (Linux-only)
-========================================================
-
-If you have a Linux system you may try to install the ``deltachat`` binary "wheel" packages
+If you have a linux system you may install the ``deltachat`` binary "wheel" package
 without any "build-from-source" steps.
 
-We suggest to `Install virtualenv <https://virtualenv.pypa.io/en/stable/installation/>`_,
-then create a fresh Python virtual environment and activate it in your shell::
+1. `Install virtualenv <https://virtualenv.pypa.io/en/stable/installation/>`_,
+   then create a fresh python environment and activate it in your shell::
 
         virtualenv venv  # or: python -m venv
         source venv/bin/activate
 
-Afterwards, invoking ``python`` or ``pip install`` only
-modifies files in your ``venv`` directory and leaves
-your system installation alone.
+   Afterwards, invoking ``python`` or ``pip install`` will only
+   modify files in your ``venv`` directory and leave your system installation
+   alone.
+
+2. Install the wheel for linux::
+

+Installing bindings from source
+===============================
+
+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::
+
+    pytest -v tests
+
+.. note::
+
+    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
+
+
+running "live" tests (experimental)
+-----------------------------------
+
+If you want to run "liveconfig" functional tests you can set
+``DCC_PY_LIVECONFIG`` to:
+
+- a particular https-url that you can ask for from the delta
+  chat devs.
+
+- or the path of a file that contains two lines, each describing
+  via "addr=... mail_pwd=..." a test account login that will
+  be used for the live tests.
+
+With ``DCC_PY_LIVECONFIG`` set pytest invocations will use real
+e-mail accounts and run through all functional "liveconfig" tests.

-# Locations
-
-Locations can be attachted to messages using
-[standard kml-files](https://www.opengeospatial.org/standards/kml/)
-with well-known names.
-
-
-## 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.

-
-To send an "Point of interest", a POI,

-and an address-attribute is not needed -
-as the location belongs to the message content,
