Part of #6884 ---- - [x] Add new chat type `InBroadcastChannel` and `OutBroadcastChannel` for incoming / outgoing channels, where the former is similar to a `Mailinglist` and the latter is similar to a `Broadcast` (which is removed) - Consideration for naming: `InChannel`/`OutChannel` (without "broadcast") would be shorter, but less greppable because we already have a lot of occurences of `channel` in the code. Consistently calling them `BcChannel`/`bc_channel` in the code would be both short and greppable, but a bit arcane when reading it at first. Opinions are welcome; if I hear none, I'll keep with `BroadcastChannel`. - [x] api: Add create_broadcast_channel(), deprecate create_broadcast_list() (or `create_channel()` / `create_bc_channel()` if we decide to switch) - Adjust code comments to match the new behavior. - [x] Ask Desktop developers what they use `is_broadcast` field for, and whether it should be true for both outgoing & incoming channels (or look it up myself) - I added `is_out_broadcast_channel`, and deprecated `is_broadcast`, for now - [x] When the user changes the broadcast channel name, immediately show this change on receiving devices - [x] Allow to change brodacast channel avatar, and immediately apply it on the receiving device - [x] Make it possible to block InBroadcastChannel - [x] Make it possible to set the avatar of an OutgoingChannel, and apply it on the receiving side - [x] DECIDE whether we still want to use the broadcast icon as the default icon or whether we want to use the letter-in-a-circle - We decided to use the letter-in-a-circle for now, because it's easier to implement, and I need to stay in the time plan - [x] chat.rs: Return an error if the user tries to modify a `InBroadcastChannel` - [x] Add automated regression tests - [x] Grep for `broadcast` and see whether there is any other work I need to do - [x] Bug: Don't show `~` in front of the sender's same in broadcast lists ---- Note that I removed the following guard: ```rust if !new_chat_contacts.contains(&ContactId::SELF) { warn!( context, "Received group avatar update for group chat {} we are not a member of.", chat.id ); } else if !new_chat_contacts.contains(&from_id) { warn!( context, "Contact {from_id} attempts to modify group chat {} avatar without being a member.", chat.id, ); } else [...] ``` i.e. with this change, non-members will be able to modify the avatar. Things were slightly easier this way, and I think that this is in line with non-members being able to modify the group name and memberlist (they need to know the Group-Chat-Id, anyway), but I can also change it back.
The chatmail core library implements low-level network and encryption protocols,
integrated by many chat bots and higher level applications,
allowing to securely participate in the globally scaled e-mail server network.
We provide reproducibly-built deltachat-rpc-server static binaries
that offer a stdio-based high-level JSON-RPC API for instant messaging purposes.
The following protocols are handled without requiring API users to know much about them:
-
secure TLS setup with DNS caching and shadowsocks/proxy support
-
safe and interoperable MIME parsing and MIME building.
-
security-audited end-to-end encryption with rPGP and Autocrypt and SecureJoin protocols
-
ephemeral Peer-to-Peer networking using Iroh for multi-device setup and webxdc realtime data.
-
a simulation- and real-world tested P2P group membership protocol without requiring server state.
Installing Rust and Cargo
To download and install the official compiler for the Rust programming language, and the Cargo package manager, run the command in your user environment:
$ curl https://sh.rustup.rs -sSf | sh
On Windows, you may need to also install Perl to be able to compile deltachat-core.
Using the CLI client
Compile and run the command line utility, using cargo:
$ cargo run --locked -p deltachat-repl -- ~/profile-db
where ~/profile-db is the database file. The utility will create it if it does not exist.
Optionally, install deltachat-repl binary with
$ cargo install --locked --path deltachat-repl/
and run as
$ deltachat-repl ~/profile-db
Configure your account (if not already configured):

Installing libdeltachat system wide
$ git clone https://github.com/chatmail/core.git
$ cd deltachat-core-rust
$ cmake -B build . -DCMAKE_INSTALL_PREFIX=/usr
$ cmake --build build
$ sudo cmake --install build
Development
# run tests
$ cargo test --all
# build c-ffi
$ cargo build -p deltachat_ffi --release
Debugging environment variables
-
DCC_MIME_DEBUG: if set outgoing and incoming message will be printed -
RUST_LOG=async_imap=trace,async_smtp=trace: enable IMAP and SMTP tracing in addition to info messages.
Expensive tests
Some tests are expensive and marked with #[ignore], to run these
use the --ignored argument to the test binary (not to cargo itself):
$ cargo test -- --ignored
Fuzzing
Install cargo-bolero with
$ cargo install cargo-bolero
Run fuzzing tests with
$ cd fuzz
$ cargo bolero test fuzz_mailparse -s NONE
Corpus is created at fuzz/fuzz_targets/corpus,
you can add initial inputs there.
For fuzz_mailparse target corpus can be populated with
../test-data/message/*.eml.
Features
vendored: When using Openssl for TLS, this bundles a vendored version.
Update Provider Data
To add the updates from the
provider-db to the core,
check line REV= inside ./scripts/update-provider-database.sh
and then run the script.
