This project uses Python 3.13. The codebase has been updated from the original Python 3.7 version to use modern Python features and updated dependencies.
This guide assumes you are using Linux and are somewhat capable with the commandline.
Running Nyaa on Windows may be possible, but it's currently unsupported.
### Major changes from NyaaV2
- Updated from Python 3.7 to Python 3.13
- Updated all dependencies to their latest versions
- Modernized code patterns for Flask 3.0 and SQLAlchemy 2.0
- Replaced deprecated Flask-Script, orderedset and `flask.Markup` with Flask CLI, orderly-set and markupsafe
- Before we get any deeper, remember to follow PEP8 style guidelines and run `python dev.py lint` before committing to see a list of warnings/problems.
- You may also use `python dev.py fix && python dev.py isort` to automatically fix some of the issues reported by the previous command.
> The database migration feature has been updated but will no longer be supported in NyaaV3.
- Database migrations are done with [Flask-Migrate](https://flask-migrate.readthedocs.io/), a wrapper around [Alembic](http://alembic.zzzcomputing.com/en/latest/).
- The migration system has been updated to use Flask CLI instead of the deprecated Flask-Script.
- If your database has never been marked by Alembic (you're on a database from before the migrations), run `python db_migrate.py db stamp head` before pulling the new migration script(s).
- If you already have the new scripts, check the output of `python db_migrate.py db history` instead and choose a hash that matches your current database state, then run `python db_migrate.py db stamp <hash>`.
- If *you* have made a change in the database schema:
- Save your changes in `models.py` and ensure the database schema matches the previous version (ie. your new tables/columns are not added to the live database)
- or [simply extracting the archives and running the files](https://www.elastic.co/guide/en/elasticsearch/reference/current/_installation.html), if you don't feel like permanently installing ES
- Edit your MariaDB/MySQL server configuration and add the following under `[mariadb]`:
```
log-bin
server_id=1
log-basename=master1
binlog-format=row
```
- Restart MariaDB/MySQL (`sudo service mysql restart`)
- Copy the example configuration (`es_sync_config.example.json`) as `es_sync_config.json` and adjust options in it to your liking (verify the connection options!)
- Connect to mysql as root
- Verify that the result of `SHOW VARIABLES LIKE 'binlog_format';` is `ROW`
- Execute `GRANT REPLICATION SLAVE ON *.* TO 'username'@'localhost';` to allow your configured user access to the binlog
- Run `./create_es.sh` to create the indices for the torrents: `nyaa` and `sukebei`
- The output should show `acknowledged: true` twice
- Stop the Nyaa app if you haven't already
- Run `python import_to_es.py` to import all the torrents (on nyaa and sukebei) into the ES indices.
- This may take some time to run if you have plenty of torrents in your database.
Enable the `USE_ELASTIC_SEARCH` flag in `config.py` and (re)start the application.
Elasticsearch should now be functional! The ES indices won't be updated "live" with the current setup, continue below for instructions on how to hook Elasticsearch up to MySQL binlog.
However, take note that binglog is not necessary for simple ES testing and development; you can simply run `import_to_es.py` from time to time to reindex all the torrents.
You're done! The script should now be feeding updates from the database to Elasticsearch.
Take note, however, that the specified ES index refresh interval is 30 seconds, which may feel like a long time on local development. Feel free to adjust it or [poke Elasticsearch yourself!](https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-refresh.html)
