Ayase Quart

About

Ayase Quart is a simple, read-only frontend for 4chan archives using the asagi schema. Please see a preview here.

This project is a descendent of Ayase. I chose to port Ayase from FastAPI over to Quart for the following reasons.

• I am more familiar with Flask environments, and Quart is practically just Flask with async and await.
• Quart has convenient extensions.
• It's been stated by numerous sources that the FastAPI developer is not supportive and does not like to accept PRs.

Set Up

Assuming you have a data source set up, you can

0. Create a file called secret.txt in /src. Populate it with random text, e.g. tr -dc A-Za-z0-9 </dev/urandom | head -c 64 > secret.txt
1. Create a file called ./src/configs.py using ./rename_to_configs.py
   • If you do not have a data source to point to, set up Neofuuka or Hayden with MySQL. See below for their details.
2. Create SSL certificates (see below) and put them in ./src. They should be called cert.pem and key.pem.
3. Create a virtualenv and install dependencies,
   • python3 -m venv venv
   • source venv/bin/activate
   • python3 -m pip install -r requirements.txt
   • sudo apt-get install python3-dev default-libmysqlclient-dev build-essential
4. python3 main.py
5. Visit https://127.0.0.1:9001 or https://<IP_ADDRESS>:9001, depending on whether you're using SSL certs.
6. Submit pull requests with fixes and new features.

Certificates

These are required to send the QUART_AUTH cookie in the server's response. Save them in ./src.

If you're on Windows, you can use Git Bash to execute the command.

openssl req -newkey rsa:2048 -new -nodes -x509 -days 3650 -keyout key.pem -out cert.pem

Themes

• Right now, only the tomorrow theme has complete support.
• If you want to modifying CSS in any way, please modify /static/css/custom.css.

Development

If you want to take debug/dev mode to the next level, you can run the following command which will keep spawning the app, even after errors are raised.

while true; do hypercorn -w 1 --reload -b 127.0.0.1:9001 'main:app'; done

Production

Here is what a systemctl service unit could look like for Ayase Quart.

sudo nano /etc/systemd/system/ayase_quart.service

[Unit]
Description=Ayase Quart - Hypercorn Service
After=network.target

Environment="PATH=/path/to/venv/bin"
ExecStart=/path/to/venv/bin/hypercorn -w 2 -b 127.0.0.1:9001 'main:app'

Type=simple

RestartSec=10

MySQL Troubleshooting

MySQL: Access denied for user 'myuser'@'localhost' (using password: YES)

This ALWAYS happens when I'm trying to run privileged transactions. Here is a solution I found for it.

DROP User 'myuser'@'localhost';
DROP User 'myuser'@'%';
CREATE USER 'myuser'@'%' IDENTIFIED BY 'mypassword';
GRANT ALL PRIVILEGES ON * . * TO 'myuser'@'%';

Neofuuka

Neofuuka is a good choice if you can't compile Hayden, or don't need Hayden's ultra low memory consumption, but note that you need to use this Neofuuka fork if you want to filter threads since it's not supported in the original version. On the other hand, Hayden supports filtering threads out-of-the-box.

To expedite schema creation, I have created ./utils/init_database.py which will create the database specified in configs.py with all the necessary tables, triggers, and indexes. Again, Hayden does this out-of-the-box.

Hayden

Setting up the Hayden Scraper on a Linux Server:

1. Build Hayden on Windows by double clicking Hayden-master/build.cmd. This will create a build-output folder with zipped builds.
2. Place the linux build on your server.
3. Run sudo ./Hayden to check if it's working. You may need to install the .NET 6.0 runtime with sudo apt install -y dotnet-runtime-6.0
4. Start Hayden with sudo ./Hayden scrape /path/to/config.json

Example config.json:

Note: You will need to create the database hayden_asagi, but Hayden takes care of generating schemas within it.
