+# deltachat-jsonrpc
+
+This crate provides a [JSON-RPC 2.0](https://www.jsonrpc.org/specification) interface to DeltaChat.
+
+The JSON-RPC API is exposed in two fashions:
+
+* A executable that exposes the JSON-RPC API through a [WebSocket](https://developer.mozilla.org/en-US/docs/Web/API/WebSockets_API) server running on localhost.
+* The JSON-RPC API can also be called through the [C FFI](../deltachat-ffi). The C FFI needs to be built with the `jsonrpc` feature. It will then expose the functions `dc_jsonrpc_init`, `dc_jsonrpc_request`, `dc_jsonrpc_next_response` and `dc_jsonrpc_unref`. See the docs in the [header file](../deltachat-ffi/deltachat.h) for details.
+
+We also include a JavaScript and TypeScript client for the JSON-RPC API. The source for this is in the [`typescript`](typescript) folder. The client can easily be used with the WebSocket server to build DeltaChat apps for web browsers or Node.js. See the [examples](typescript/example) for details.
+
+## Usage
+
+#### Running the WebSocket server
+
+From within this folder, you can start the WebSocket server with the following command:
+
+```sh
+cargo run --features webserver
+```
+
+If you want to use the server in a production setup, first build it in release mode:
+
+```sh
+cargo build --features webserver --release
+```
+You will then find the `deltachat-jsonrpc-server` executable in your `target/release` folder.
+
+The executable currently does not support any command-line arguments. By default, once started it will accept WebSocket connections on `ws://localhost:20808/ws`. It will store the persistent configuration and databases in a `./accounts` folder relative to the directory from where it is started.
+
+The server can be configured with environment variables:
+
+|variable|default|description|
+|-|-|-|
+|`DC_PORT`|`20808`|port to listen on|
+|`DC_ACCOUNTS_PATH`|`./accounts`|path to storage directory|
+
+If you are targetting other architectures (like KaiOS or Android), the webserver binary can be cross-compiled easily with [rust-cross](https://github.com/cross-rs/cross):
+
+```sh
+cross build --features=webserver --target armv7-linux-androideabi --release
+```
+
+#### Using the TypeScript/JavaScript client
+
+The package includes a JavaScript/TypeScript client which is partially auto-generated through the JSON-RPC library used by this crate ([yerpc](https://github.com/Frando/yerpc/)). Find the source in the [`typescript`](typescript) folder. 
+
+To use it locally, first install the dependencies and compile the TypeScript code to JavaScript:
+```sh
+cd typescript
+npm install
+npm run build
+```
+
+The JavaScript client is not yet published on NPM (but will likely be soon). Currently, it is recommended to vendor the bundled build. After running `npm run build` as documented above, there will be a file `dist/deltachat.bundle.js`. This is an ESM module containing all dependencies. Copy this file to your project and import the DeltaChat class.
+
+
+```typescript
+import { DeltaChat } from './deltachat.bundle.js'
+const dc = new DeltaChat('ws://localhost:20808/ws')
+const accounts = await dc.rpc.getAllAccounts()
+console.log('accounts', accounts)
+```
+
+A script is included to build autogenerated documentation, which includes all RPC methods:
+```sh
+cd typescript
+npm run docs
+```
+Then open the [`typescript/docs`](typescript/docs) folder in a web browser.
+
+## Development
+
+#### Running the example app
+
+We include a small demo web application that talks to the WebSocket server. It can be used for testing. Feel invited to expand this.
+
+```sh
+cd typescript
+npm run build
+npm run example:build
+npm run example:start
+```
+Then, open [`http://localhost:8080/example.html`](http://localhost:8080/example.html) in a web browser.
+
+Run `npm run example:dev` to live-rebuild the example app when files changes.
+
+### Testing
+
+The crate includes both a basic Rust smoke test and more featureful integration tests that use the TypeScript client.
+
+#### Rust tests
+
+To run the Rust test, use this command:
+
+```
+cargo test
+```
+
+#### TypeScript tests
+
+```
+cd typescript
+npm run test
+```
+
+This will build the `deltachat-jsonrpc-server` binary and then run a test suite against the WebSocket server.
+
+The test suite includes some tests that need online connectivity and a way to create test email accounts. To run these tests, talk to DeltaChat developers to get a token for the `testrun.org` service, or use a local instance of [`mailadm`](https://github.com/deltachat/docker-mailadm).
+
+Then, set the `DCC_NEW_TMP_EMAIL` environment variable to your mailadm token before running the tests.
+
+```
+DCC_NEW_TMP_EMAIL=https://testrun.org/new_email?t=yourtoken npm run test
+```
+
+#### Test Coverage
+
+Running `npm run test` will report test coverage. For the coverage to be accurate the online tests need to be run.
+
+> If you are offline and want to see the coverage results anyway (even though they are inaccurate), you can bypass the errors of the online tests by setting the `COVERAGE_OFFLINE=1` environment variable.
+
+A summary of the coverage will be reported in the terminal after the test run. Open `coverage/index.html` in a web browser for a detailed report.

+# TODO
+
+- [ ] different test type to simulate two devices: to test autocrypt_initiate_key_transfer & autocrypt_continue_key_transfer
+
+## MVP - Websocket server&client
+
+For kaiOS and other experiments, like a deltachat "web" over network from an android phone.
+
+- [ ] coverage for a majority of the API
+- [ ] Blobs served
+- [ ] Blob upload (for attachments, setting profile-picture, importing backup and so on)
+- [ ] other way blobs can be addressed when using websocket vs. jsonrpc over dc-node
+- [ ] Web push API? At least some kind of notification hook closure this lib can accept.
+
+### Other Ideas for the Websocket server
+
+- [ ] make sure there can only be one connection at a time to the ws
+  - why? , it could give problems if its commanded from multiple connections
+- [ ] encrypted connection?
+- [ ] authenticated connection?
+- [ ] Look into unit-testing for the proc macros?
+- [ ] proc macro taking over doc comments to generated typescript file
+
+## Desktop Apis
+
+Incomplete todo for desktop api porting, just some remainders for points that might need more work:
+
+- [ ] manual start/stop io functions in the api for context and accounts, so "not syncing all accounts" can still be done in desktop -> webserver should then not do start io on all accounts by default

+AEAP MVP
+========
+
+Changes to the UIs
+------------------
+
+- The secondary self addresses (see below) are shown in the UI, but not editable.
+
+- When the user changed the email address in the configure screen, show a dialog to the user, either directly explaining things or with a link to the FAQ (see "Other" below)
+
+Changes in the core
+-------------------
+
+- [x] We have one primary self address and any number of secondary self addresses. `is_self_addr()` checks all of them.
+
+- [x] 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.
+
+- [x] No changes for 1:1 chats, there simply is a new one. (This works since, contrary to group messages, messages sent to a 1:1 chat are not assigned to the group chat but always to the 1:1 chat with the sender. So it's not a problem that the new messages might be put into the old chat if they are a reply to a message there.)
+
+- [ ] When sending a message: If any of the secondary self addrs is in the chat's member list, remove it locally (because we just transitioned away from it). We add a log message for this (alternatively, a system message in the chat would be more visible).
+
+- [x] ([#3385](https://github.com/deltachat/deltachat-core-rust/pull/3385)) When receiving a message: If the key exists, but belongs to another address (we may want to benchmark this)
+  AND there is a `Chat-Version` header\
+  AND the message is signed correctly
+  AND the From address is (also) in the encrypted (and therefore signed) headers <sup>[[1]](#myfootnote1)</sup>\
+  AND the message timestamp is newer than the contact's `lastseen` (to prevent changing the address back when messages arrive out of order) (this condition is not that important since we will have eventual consistency even without it):
+
+  Replace the contact in _all_ groups, possibly deduplicate the members list, and add a system message to all of these chats.
+  
+  - Note that we can't simply compare the keys byte-by-byte, since the UID may have changed, or the sender may have rotated the key and signed the new key with the old one.
+
+<a name="myfootnote1">[1]</a>: Without this check, an attacker could replay a message from Alice to Bob. Then Bob's device would do an AEAP transition from Alice's to the attacker's address, allowing for easier phishing.
+
+<details>
+<summary>More details about this</summary>
+Suppose Alice sends a message to Evil (or to a group with both Evil and Bob). Evil then forwards the message to Bob, changing the From and To headers (and if necessary Message-Id) and replacing `addr=alice@example.org;` in the autocrypt header with `addr=evil@example.org;`.
+
+Then Bob's device sees that there is a message which is signed by Alice's key and comes from Evil's address and would do the AEAP transition, i.e. replace Alice with Evil in all groups and show a message "Alice changed their address from alice@example.org to evil@example.org". Disadvantages for Evil are that Bob's message will be shown on Alice's device, possibly creating confusion/suspicion, and that the usual "Setup changed for..." message will be shown the next time Evil sends a message (because Evil doesn't know Alice's private key).
+
+Possible mitigations:
+- if we make the AEAP device message sth. like "Automatically removed alice@example.org and added evil@example.org", then this will create more suspicion, making the phishing harder (we didn't talk about what what the wording should be at all yet).
+- Add something similar to replay protection to our Autocrypt implementation. This could be done e.g. by adding a second `From` header to the protected headers. If it's present, the receiver then requires it to be the same as the outer `From`, and if it's not present, we don't do AEAP --> **That's what we implemented**
+
+Note that usually a mail is signed by a key that has a UID matching the from address.
+
+  That's not mandatory for Autocrypt (and in fact, we just keep the old UID when changing the self address, so with AEAP the UID will actually be different than the from address sometimes)
+
+  https://autocrypt.org/level1.html#openpgp-based-key-data says:
+  > The content of the user id packet is only decorative
+
+</details>
+
+### Notes:
+  
+- We treat protected and non-protected chats the same
+- We leave the aeap transition statement away since it seems not to be needed, makes things harder on the sending side, wastes some network traffic, and is worse for privacy (since more pepole know what old addresses you had).
+- As soon as we encrypt read receipts, sending a read receipt will be enough to tell a lot of people that you transitioned
+- AEAP will make the problem of inconsistent group state worse, both because it doesn't work if the message is unencrypted (even if the design allowed it, it would be problematic security-wise) and because some chat partners may have gotten the transition and some not. We should do something against this at some point in the future, like asking the user whether they want to add/remove the members to restore consistent group state.
+
+#### Downsides of this design:
+- Inconsistent group state: Suppose Alice does an AEAP transition and sends a 1:1 message to Bob, so Bob rewrites Alice's contact. Alice, Bob and Charlie are together in a group. Before Alice writes to this group, Bob and Charlie will have different membership lists, and Bob will send messages to Alice's new address, while Charlie will send them to her old address.
+
+#### Upsides:
+- With this approach, it's easy to switch to a model where the info about the transition is encoded in the PGP key. Since the key is gossiped, the information about the transition will spread virally.
+- Faster transation: If you send a message to e.g. "Delta Chat Dev", all members of the "sub-group" "delta android" will know of your transition.
+
+### Alternatives and old discussions/plans:
+
+- Change the contact instead of rewriting the group member lists. This seems to call for more trouble since we will end up with multiple contacts having the same email address.
+
+- If needed, we could add a header a) indicating that the sender did an address transition or b) listing all the secondary (old) addresses.  For now, there is no big enough benefit to warrant introducing another header and its processing on the receiver side (including all the neccessary checks and handling of error cases). Instead, we only check for the `Chat-Version` header to prevent accidental transitions when an MUA user sends a message from another email address with the same key.
+
+- The condition for a transition temporarily was:
+
+  > When receiving a message: If we are going to assign a message to a chat, but the sender is not a member of this chat\
+  > AND the signing key is the same as the direct (non-gossiped) key of one of the chat members\
+  > AND ...
+
+  However, this would mean that in 1:1 messages can't trigger a transition, since we don't assign private messages to the parent chat, but always to the 1:1 chat with the sender.
+  
+<details>
+<summary>Some previous state of the discussion, which temporarily lived in an issue description</summary>
+Summarizing the discussions from https://github.com/deltachat/deltachat-core-rust/pull/2896, mostly quoting @hpk42:
+
+1. (DONE) At the time of configure we push the current primary to become a secondary. 
+
+2. When a message is sent out to a chat, and the message is encrypted, and we have secondary addresses, then we 
+  a) add a protected "AEAP-Replacement" header that contains all secondary addresses 
+  b) if any of the secondary addresses is in the chat's member list, we remove it and leave a system message that we did so
+3. When an encrypted message with a replacement header is received, replace the e-mail address of all secondary contacts (if they exist) with the new primary and drop a sysmessage in all chats the secondary is member off.  This might (in edge cases) result in chats that have two or more contacts with the same e-mail address.  We might ignore this for a first release and just log a warning.  Let's maybe not get hung up on this case before everything else works. 
+
+Notes: 
+- for now we will send out aeap replacement headers forever, there is no termination condition other than lack of secondary addresses.  I think that's fine for now.  Later on we might introduce options to remove secondary addresses but i wouldn't do this for a first release/PR. 
+- the design is resilient against changing e-mail providers from A to B to C and then back to A, with partially updated chats and diverging views from recipients/contacts on this transition.  In the end, you will have a primary and some secondaries, and when you start sending out messages everybody will eventually synchronize when they receive the current state of primaries/secondaries. 
+- of course on incoming message for need to check for each stated secondary address in the replacement header that it uses the same signature as the signature we verified as valid with the incoming message  **-->  Also we have to somehow make sure that the signing key was not just gossiped from some random other person in some group.**
+- there are no extra flags/columns in the database needed (i hope) 
+
+#### Downsides of the chosen approach:
+- Inconsistent group state: Suppose Alice does an AEAP transition and sends a 1:1 message to Bob, so Bob rewrites Alice's contact. Alice, Bob and Charlie are together in a group. Before Alice writes to this group, Bob and Charlie will have different membership lists, and Bob will send messages to Alice's new address, while Charlie will send them to her old address.
+- There will be multiple contacts with the same address in the database. We will have to do something against this at some point.
+
+The most obvious alternative would be to create a new contact with the new address and replace the old contact in the groups.
+
+#### Upsides:
+- With this approach, it's easier to switch to a model where the info about the transition is encoded in the PGP key. Since the key is gossiped, the information about the transition will spread virally.
+- (Also, less important: Slightly faster transation: If you send a message to e.g. "Delta Chat Dev", all members of the "sub-group" "delta android" will know of your transition.)
+- It's easier to implement (if too many problems turn up, we can still switch to another approach and didn't wast that much development time.)

+========================

+- As far as I understand the code, unencrypted messages are unsigned. So, the transition only works if both sides have the other side's key.

-- When the user changed the email address in the configure screen, show a dialog to the user, either directly explaining things or with a link to the FAQ (see "Other" below)

-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 APIs and Tags Usage Hints
+
+- `localStorage`, `sessionStorage`, `indexedDB` are okay to be used
+- `visibilitychange`-events are okay to be used
+- `window.navigator.language` is okay to be used, on desktop it is the system language
+- `<a href="localfile.html">` and other internal links are okay to be used
+- `<a href="mailto:addr@example.org?body=...">`- mailto links are okay to be used
+- `<meta name="viewport" ...>` usage is okay to be used
+  and useful esp. different webviews have different defaults
+
+
+### Discouraged Things
+
+- `document.cookie` is known not to work on desktop and iOS
+  use `localStorage` instead
+- `unload`-, `beforeunload`- and `pagehide`-events are known not to work on iOS and are flaky on other systems
+  (also partly discouraged by [mozilla](https://developer.mozilla.org/en-US/docs/Web/API/Window/unload_event))
+  use `visibilitychange` instead
+- `<title>` and `document.title` is ignored by Webxdc;
+  use the `name` property from `manifest.toml` instead
+- newest js features may not work on all webviews,
+  you may want to transpile your code down to an older js version
+  eg. with <https://babeljs.io>
+- `<a href="https://example.org/foo">` and other external links are blocked by definition;
+  instead, embed content or use `mailto:` link to offer a way for contact
+- `<input type="file">` is discouraged currently; this may change in future
+

-## 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
-- viewport and scaling features are implementation specific,
-  if you want to have an explicit behavior, you can add eg.
-  `<meta name="viewport" content="initial-scale=1; user-scalable=no">` to your Webxdc
-- the `<title>` tag should not be used and its content is usually not displayed;
-  instead, use the `name` property from `manifest.toml`
-- 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.

 If you have a Linux system you may try to install the ``deltachat`` binary "wheel" packages
 without any "build-from-source" steps.
-Otherwise you need to `compile the Delta Chat bindings yourself <#sourceinstall>`_.

 We recommend to first `install virtualenv <https://virtualenv.pypa.io/en/stable/installation.html>`_,
 then create a fresh Python virtual environment and activate it in your shell::
 
-        virtualenv venv  # or: python -m venv
-        source venv/bin/activate
+        virtualenv env  # or: python -m venv
+        source env/bin/activate
 
 Afterwards, invoking ``python`` or ``pip install`` only

+index. To install the latest release::
 
-    pip install --pre -i https://m.devpi.net/dc/master deltachat
+    pip install deltachat
 
 To verify it worked::
 
     python -c "import deltachat"
 
-.. note::
-
-    If you can help to automate the building of wheels for Mac or Windows,
-    that'd be much appreciated! please then get

 Running tests
 =============
 
-After successful binding installation you can install a few more
-Python packages before running the tests::
+Recommended way to run tests is using `tox <https://tox.wiki>`_.
+After successful binding installation you can install tox
+and run the tests::
 
-    python -m pip install pytest pytest-xdist pytest-timeout pytest-rerunfailures requests
-    pytest -v tests
+    pip install tox
+    tox -e py3
 
 This will run all "offline" tests and skip all functional
 end-to-end tests that require accounts on real e-mail servers.

-   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::

 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.

-using docker pull / premade images
-------------------------------------
+.. _Docker: https://www.docker.com/
+.. _Podman: https://podman.io/
 
-We publish a build environment under the ``deltachat/coredeps`` tag so
-that you can pull it from the ``hub.docker.com`` site's "deltachat"
-organization::
+If you want to build your own wheels, build container image first::
 
-    $ docker pull deltachat/coredeps

+   $ docker build -t deltachat/coredeps scripts/coredeps

-If you want to build your own custom docker image you can do this::
-
-   $ cd deltachat-core # cd to deltachat-core checkout directory
