* Clean up PR #349
- Rely on os.makedirs(..., exist_ok=True) for "thread"-safety
- Remove the previous info_dict when we know the transaction went through.
- bytes.hex() will always be lowercase (unless we go off CPython):
c3d9508ff2/Python/pystrhex.c (L5-L49)c3d9508ff2/Python/codecs.c (L16)
- Reintroduce comments and meaningful creation dates in generated torrents:
Also make create_default_metadata_base set the correct metadata now
With all trackers.txt trackers being included in generated .torrents,
we can now be certain the magnet (which use trackers.txt) and the .torrent
uses will not be split up in different swarms in case the main announce dies.
(That is, if uploaders add enough of their own trackers and additional trackers
were deemed unnecessary (at least 5 already), the magnet and .torrent would only
share the main site announce)
* Replace all `from nyaa import app` imports with `app = flask.current_app` (or `from flask import current_app as app` where possible)
* Add a separate config object for top-level and class statements as `nyaa.extensions.config`
Required because those codes don't have app context at the time of evaluation/execution.
* Remove `routes.py` file and register all blueprints in `nyaa/__init__.py`
* Refactor `nyaa/__init__.py` into an app factory
* Update tools
* Update tests (temporary, will be replaced)
* Update isort settings
* Apply import sorting (isort) on all files in nyaa/
* Fixed Flake8 errors in nyaa/ (see PR for list)
* Add isort to lint.sh and requirements.txt
