+# Continuous Integration Scripts for Delta Chat
+
+Continuous Integration is run through CircleCI
+but is largely independent of it. 
+
+
+## Generating docker containers for performing build step work 
+
+All tests, docs and wheel building is run in docker containers:
+
+- **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). 
+
+- **doxygen/Dockerfile** specifies an image that contains
+  the doxygen tool which is used to generate C-docs. 
+
+To run tests locally you can pull existing images from "docker.io",
+the hub for sharing Docker images::
+
+    docker pull deltachat/coredeps
+    docker pull deltachat/doxygen 
+
+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`

-Changes in the core
--------------------
-
-- We have one primary self address and any number of secondary self addresses. `is_self_addr()` checks all of them.
-
-- If the user does a reconfigure and changes the email address, the previous address is added as a secondary self address.
-
-  - don't forget to deduplicate secondary self addresses in case the user switches back and forth between addresses).
-
-  - The key stays the same.
-
-- No changes for 1:1 chats, there simply is a new one
-
-- When we send a message to a group, and the primary address is not a member of a group, but a secondary address is:
-  
-  Add Chat-Group-Member-Removed=<old address> and Chat-Group-Member-Added=<new address> headers to this message
-
-  - On the receiving side, make sure that we accept this (even in verified groups) if the message is signed and the key stayed the same
-
-Other

-- The user is responsible that messages to the old address arrive at the new address, for example by configuring the old provider to forward all emails to the new one.

-Problem: missing eventual group consistency
---------------------------------------------
-
-If group members are concurrently adding new members,
-the new members will miss each other's additions, example:
-
-1. Alice and Bob are in a two-member group
-
-2. Then Alice adds Carol, while concurrently Bob adds Doris
-
-Right now, the group has inconsistent memberships:
-
-- Alice and Carol see a (Alice, Carol, Bob) group
-
-- Bob and Doris see a (Bob, Doris, Alice)
-
-This then leads to "sender is unknown" messages in the chat,
-for example when Alice receives a message from Doris,
-or when Bob receives a message from Carol.
-
-There are also other sources for group membership inconsistency:
-
-- leaving/deleting/adding in larger groups, while being offline,
-  increases chances for inconsistent group membership
-
-- dropped group-membership messages
-
-- group-membership messages landing in "Spam"
-
-
-Note that all these problems (can) also happen with verified groups,
-then raising "false alarms" which could lure people to ignore such issues.
-
-IOW, it's clear we need to do something about it to improve overall
-reliability in group-settings.
-
-
-
-Solution: replay group modification messages on inconsistencies
-------------------------------------------------------------------
-
-For brevity let's abbreviate "group membership modification" as **GMM**.
-
-Delta chat has explicit GMM messages, typically encrypted to the group members
-as seen by the device that sends the GMM. The `Spec <https://github.com/deltachat/deltachat-core-rust/blob/master/spec.md#add-and-remove-members>`_ details the Mime headers and format.
-
-If we detect membership inconsistencies we can resend relevant GMM messages
-to the respective chat.  The receiving devices can process those GMM messages
-as if it would be an incoming message. If for example they have already seen
-the Message-ID of the GMM message, they will ignore the message. It's
-probably useful to record GMM message in their original MIME-format and
-not invent a new recording format. Few notes on three aspects:
-
-- **group-membership-tracking**: All valid GMM messages are persisted in
-  their full raw (signed/encrypted?) MIME-format in the DB. Note that GMM messages
-  already are in the msgs table, and there is a mime_header column which we could
-  extend to contain the raw Mime GMM message.
-
-- **consistency_checking**: If an incoming GMM has a member list which is
-  not consistent with our own view, broadcast a "Group-Member-Correction"
-  message to all members containing a multipart list of GMMs.
-
-- **correcting_memberships**: Upon receiving a Group-Member-Correction
-  message we pass the contained GMMs to the "incoming mail pipeline"
-  (without **consistency_checking** them, to avoid recursion issues)
-
-
-Alice/Carol and Bob/Doris getting on the same page
-++++++++++++++++++++++++++++++++++++++++++++++++++
-
-Recall that Alice/Carol and Bob/Doris had a differening view of
-group membership. With the proposed solution, when Bob receives
-Alice's "Carol added" message, he will notice that Alice (and thus
-also carol) did not know about Doris.  Bob's device sends a
-"Chat-Group-Member-Correction" message containing his own GMM
-when adding Doris. Therefore, the group's membership is healed
-for everyone in a single broadcast message.
-
-Alice might also send a Group-member-Correction message,
-so there is a second chance that the group gets to know all GMMs.
-
-Note, for example, that if for some reason Bobs and Carols provider
-drop GMM messages between them (spam) that Alice and Doris can heal
-it by resending GMM messages whenever they detect them to be out of sync.
-
-
-Discussions of variants
-++++++++++++++++++++++++
-
-- instead of acting on GMM messages we could send corrections
-  for any received message that addresses inconsistent group members but
-  a) this could delay group-membership healing
-  b) could lead to a lot of members sending corrections
-  c) means we might rely on "To-Addresses" which we also like to strike
-     at least for protected chats.
-
-- 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).

-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.

-# Webxdc Developer Reference
-
-## Webxdc File Format
-
-- a **Webxdc app** is a **ZIP-file** with the extension `.xdc`
-- the ZIP-file must use the default compression methods as of RFC 1950,
-  this is "Deflate" or "Store"
-- the ZIP-file must contain at least the file `index.html`
-- if the Webxdc app is started, `index.html` is opened in a restricted webview
-  that allow accessing resources only from the ZIP-file
-
-
-## Webxdc API
-
-There are some additional APIs available once `webxdc.js` is included
-(the file will be provided by the concrete implementations,
-no need to add `webxdc.js` to your ZIP-file):
-
-```html
-<script src="webxdc.js"></script>
-```
-
-### sendUpdate()
-
-```js
-window.webxdc.sendUpdate(update, descr);
-```
-
-Webxdc apps are usually shared in a chat and run independently on each peer.
-To get a shared state, the peers use `sendUpdate()` to send updates to each other.
-
-- `update`: an object with the following properties:  
-    - `update.payload`: any javascript primitive, array or object.
-    - `update.info`: optional, short, informational message that will be added to the chat,
-       eg. "Alice voted" or "Bob scored 123 in MyGame";
-       usually only one line of text is shown,
-       use this option sparingly to not spam the chat.
-    - `update.summary`: optional, short text, shown beside app icon;
-       it is recommended to use some aggregated value,  eg. "8 votes", "Highscore: 123"
-
-- `descr`: short, human-readable description what this update is about.
-  this is shown eg. as a fallback text in an email program.
-
-All peers, including the sending one,
-will receive the update by the callback given to `setUpdateListener()`.
-
-There are situations where the user cannot send messages to a chat,
-eg. if the webxdc instance comes as a contact request or if the user has left a group.
-In these cases, you can still call `sendUpdate()`,
-however, the update won't be sent to other peers
-and you won't get the update by `setUpdateListener()`.
-
-
-### setUpdateListener()
-
-```js
-window.webxdc.setUpdateListener((update) => {}, serial);
-```
-
-With `setUpdateListener()` you define a callback that receives the updates
-sent by `sendUpdate()`. The callback is called for updates sent by you or other peers.
-The `serial` specifies the last serial that you know about (defaults to 0). 
-
-Each `update` which is passed to the callback comes with the following properties: 
-
-- `update.payload`: equals the payload given to `sendUpdate()`
-
-- `update.serial`: the serial number of this update.
-  Serials are larger `0` and newer serials have higher numbers.
-  There may be gaps in the serials
-  and it is not guaranteed that the next serial is exactly incremented by one.
-
-- `update.max_serial`: the maximum serial currently known.
-  If `max_serial` equals `serial` this update is the last update (until new network messages arrive).
-
-- `update.info`: optional, short, informational message (see `send_update`) 
-
-- `update.summary`: optional, short text, shown beside app icon (see `send_update`)
-
-
-### selfAddr
-
-```js
-window.webxdc.selfAddr
-```
-
-Property with the peer's own address.
-This is esp. useful if you want to differ between different peers -
-just send the address along with the payload,
-and, if needed, compare the payload addresses against selfAddr() later on.
-
-
-### selfName
-
-```js
-window.webxdc.selfName
-```
-
-Property with the peer's own name.
-This is name chosen by the user in their settings,
-if there is nothing set, that defaults to the peer's address.
-
-
-## manifest.toml
-
-If the ZIP-file contains a `manifest.toml` in its root directory,
-some basic information are read and used from there.
-
-the `manifest.toml` has the following format
-
-```toml
-name = "My App Name"
-```
-
-- **name** - The name of the app.
-  If no name is set or if there is no manifest, the filename is used as the app name.
-
-
-## App Icon
-
-If the ZIP-root contains an `icon.png` or `icon.jpg`,
-these files are used as the icon for the app.
-The icon should be a square at reasonable width/height;
-round corners etc. will be added by the implementations as needed.
-If no icon is set, a default icon will be used.
-
-
-## Webxdc Examples
-
-The following example shows an input field and  every input is show on all peers.
-
-```html
-<!DOCTYPE html>
-<html>
-  <head>
-    <meta charset="utf-8"/>
-    <script src="webxdc.js"></script>
-  </head>
-  <body>
-    <input id="input" type="text"/>
-    <a href="" onclick="sendMsg(); return false;">Send</a>
-    <p id="output"></p>
-    <script>
-    
-      function sendMsg() {
-        msg = document.getElementById("input").value;
-        window.webxdc.sendUpdate({payload: msg}, 'Someone typed "'+msg+'".');
-      }
-    
-      function receiveUpdate(update) {
-        document.getElementById('output').innerHTML += update.payload + "<br>";
-      }
-    
-      window.webxdc.setUpdateListener(receiveUpdate, 0);
-    </script>
-  </body>
-</html>
-```
-
-[Webxdc Development Tool](https://github.com/deltachat/webxdc-dev)
-offers an **Webxdc Simulator** that can be used in many browsers without any installation needed.
-You can also use that repository as a template for your own app -
-just clone and start adapting things to your need.
-
-
-### Advanced Examples
-
-- [2048](https://github.com/adbenitez/2048.xdc)
-- [Draw](https://github.com/adbenitez/draw.xdc)
-- [Poll](https://github.com/r10s/webxdc-poll/)
-- [Tic Tac Toe](https://github.com/Simon-Laux/tictactoe.xdc)
-- Even more with [Topic #webxdc on Github](https://github.com/topics/webxdc)
-
-
-## Closing Remarks
-
-- older devices might not have the newest js features in their webview,
-  you may want to transpile your code down to an older js version eg. with https://babeljs.io
-- there are tons of ideas for enhancements of the API and the file format,
-  eg. in the future, we will may define icon- and manifest-files,
-  allow to aggregate the state or add metadata.

+   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
+
+   (b) You must cause any modified files to carry prominent notices
+       stating that You changed the files; and

+
+   (d) If the Work includes a "NOTICE" text file as part of its

+       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,

+   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

+   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.

+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`` to a URL that creates e-mail accounts.  Most developers use https://testrun.org URLS created and managed by [mailadm](https://mailadm.readthedocs.io/en/latest/).
-
-Please feel free to contact us through a github issue or by e-mail and we'll send you a URL that you can then use for functional tests like this:
-
-    export DCC_NEW_TMP_EMAIL=<URL you got from us>
-
-With this account-creation setting, pytest runs create ephemeral e-mail accounts on the http://testrun.org server.  These accounts exists only for one hour 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.

-.. _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.
