thread '<unnamed>' panicked at src/net/channel.rs:314:32:
called `Option::unwrap()` on a `None` value
So the bug is caused after running p2p.seed(), where after
channel.stop() is called, main_receive_loop() keeps running. Examining
the code further we see ch.stop().await is called and the session is
destroyed but this doesn't give enough time for the channel to finish.
One solution is to modify `net/session/seedsync_session.rs` to this:
let stop_sub = ch.subscribe_stop().await;
ch.stop().await;
stop_sub.recv().await;
stop_sub.unsubscribe().await;
However a better solution is to make channel.stop() itself await until
the channel is fully closed (using the above code inside Channel::stop())
But the better solution is to ensure that StoppableTask.stop() itself
will not finish until the task it's responsible for has finished and
is no longer running. We do that by adding a stop barrier (see diff).

About DarkFi
DarkFi is a new Layer 1 blockchain, designed with anonymity at the forefront. It offers flexible private primitives that can be wielded to create any kind of application. DarkFi aims to make anonymous engineering highly accessible to developers.
DarkFi uses advances in zero-knowledge cryptography and includes a contracting language and developer toolkits to create uncensorable code.
In the open air of a fully dark, anonymous system, cryptocurrency has the potential to birth new technological concepts centered around sovereignty. This can be a creative, regenerative space - the dawn of a Dark Renaissance.

Follow the installation instructions for the P2P IRC daemon.
Build
This project requires the Rust compiler to be installed. Please visit Rustup for instructions.
You have to install a native toolchain, which is set up during Rust installation, nightly toolchain and wasm32 target. To install nightly toolchain, execute:
% rustup toolchain install nightly
To install wasm32 target, execute:
% rustup target add wasm32-unknown-unknown
% rustup target add wasm32-unknown-unknown --toolchain nightly
Minimum Rust version supported is 1.67.0 (stable).
The following dependencies are also required:
| Dependency | Debian-based |
|---|---|
| git | git |
| make | make |
| gcc | gcc |
| pkg-config | pkg-config |
| alsa-lib | libasound2-dev |
| openssl | libssl-dev |
| sqlcipher | libsqlcipher-dev |
Users of Debian-based systems (e.g. Ubuntu) can simply run the following to install the required dependencies:
# apt-get update
# apt-get install -y git make gcc pkg-config libasound2-dev libssl-dev libsqlcipher-dev
Alternatively, users can try using the automated script under contrib
folder by executing:
% sh contrib/dependency_setup.sh
The script will try to recognize which system you are running, and install dependencies accordingly. In case it does not find your package manager, please consider adding support for it into the script and sending a patch.
To build the necessary binaries, we can just clone the repo, checkout to the latest tag, and use the provided Makefile to build the project:
% git clone https://github.com/darkrenaissance/darkfi
% cd darkfi && git checkout v0.4.1
% make
Development
If you want to hack on the source code, make sure to read some introductory advice in the DarkFi book.
Install
This will install the binaries on your system (/usr/local by
default). The configuration files for the binaries are bundled with the
binaries and contain sane defaults. You'll have to run each daemon once
in order for them to spawn a config file, which you can then review.
# make install
