Simon Laux bfc58e9204 feat: receive pre-messages and adapt download on demand
fix python lint errors

receive pre-mesages, start with changes to imap loop.

refactor: move download code from `scheduler.rs` to `download.rs`, also
move `get_msg_id_by_rfc724_mid` to `MsgId::get_by_rfc724_mid`

`MAX_FETCH_MSG_SIZE` is no longer unused

Parse if it is a pre-message or full-message

start with receiving logic

get rid of `MsgId::get_by_rfc724_mid` because it was a duplicate of
`message::rfc724_mid_exists`

docs: add hint to `MimeMessage::from_bytes` stating that it has
side-effects.

receiving full message

send and receive `attachment_size` and set viewtype to text in
pre_message

metadata as struct in pre-message in header. And fill params that we can
already fill from the metadata. Also add a new api to check what
viewtype the message will have once downloaded.

api: jsonrpc: add `full_message_view_type` to `Message` and
`MessageInfo`

make PreMsgMetadata.to_header_value not consume self/PreMsgMetadata

add api to merge params

on download full message: merge new params into old params and remove
full-message metadata params

move tests to `src/tests/pre_messages.rs`

dynamically allocate test attachment bytes

fix detection of pre-messages. (it looked for the ChatFullMessageId
header in the unencrypted headers before)

fix setting dl state to avaiable on pre-messages

fix: save pre message with rfc724_mid of full message als disable
replacement for full messages

add some receiving tests and update test todo for premessage metadata

test: process full message before pre-message

test receive normal message

some serialization tests for PreMsgMetadata

remove outdated todo comment

test that pre-message contains message text

PreMsgMetadata: test_build_from_file_msg and test_build_from_file_msg

test: test_receive_pre_message_image

Test receiving the full message after receiving an edit after receiving
the pre-message

test_reaction_on_pre_message

test_full_download_after_trashed

test_webxdc_update_for_not_downloaded_instance

simplify fake webxdc generation in
test_webxdc_update_for_not_downloaded_instance

test_markseen_pre_msg

test_pre_msg_can_start_chat and test_full_msg_can_start_chat

test_download_later_keeps_message_order

test_chatlist_event_on_full_msg_download

fix download not working

log splitting into pre-message

add pre-message info to text when loading from db. this can be disabled
with config key `hide_pre_message_metadata_text` if ui wants to display
it in a prettier way.

update `download_limit` documentation

more logging: log size of pre and post messages

rename full message to Post-Message

split up the pre-message tests into multiple files

dedup test code by extracting code to create test messages into util
methods

remove post_message_view_type from api, now it is only used internally
for tests

remove `hide_pre_message_metadata_text` config option, as there
currently is no way to get the full message viewtype anymore

Update src/download.rs
resolve comment

use `parse_message_id` instead of removing `<>`parenthesis it manually

fix available_post_msgs gets no entries
handle forwarding and add a test for it.

convert comment to log warning event on unexpected download failure

add doc comment to `simple_imap_loop`

more logging

handle saving pre-message to self messages and test.

deltachat-jsonrpc

This crate provides a JSON-RPC 2.0 interface to DeltaChat.

The JSON-RPC API is exposed in two fashions:

  • A executable deltachat-rpc-server that exposes the JSON-RPC API through stdio.
  • The JSON-RPC API can also be called through the C FFI. It exposes the functions dc_jsonrpc_init, dc_jsonrpc_request, dc_jsonrpc_next_response and dc_jsonrpc_unref. See the docs in the header file for details.

We also include a JavaScript and TypeScript client for the JSON-RPC API. The source for this is in the typescript folder.

Usage

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). Find the source in the typescript folder.

To use it locally, first install the dependencies and compile the TypeScript code to JavaScript:

cd typescript
npm install
npm run build

The JavaScript client is published on NPM.

A script is included to build autogenerated documentation, which includes all RPC methods:

cd typescript
npm run docs

Then open the typescript/docs folder in a web browser.

Development

Running the example app

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.

The test suite includes some tests that need online connectivity and a way to create test email accounts. To run these tests, set the CHATMAIL_DOMAIN environment variable to your testing email server domain.

CHATMAIL_DOMAIN=ci-chatmail.testrun.org 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.
