The Flask-Caching cache can now properly be configured from the
config.py, and redis caching has experimentally been tested and
confirmed to be working in theory.
We also document that one may want to use CACHE_THRESHOLD to limit
the maximum number of items in the simple cache.
This commit adds a caching_url_for using functools.lru_cache (currently
with maxsize at 4096 entries) and replaces flask.url_for with it, as
there is no harm in doing so.
This greatly improves template generation speed, from ~115ms to ~75ms on
the front page (using the simple benchmark introduced in the previous
commit).
Using Flask-Caching, we can memoize the magnet_uri method. Here, a
timeout of 1 hour is chosen, though that value can be fiddled with.
The cache is defined in extensions.py, but gets initialised in
__init__.py.
* Add config option to enable/disable gravatar
This is useful when running a development instance behind a firewall
or NAT, where gravatar cannot reach you to serve up the default user
avatar.
* Pregenerate Gravatar default image URLs
If possible (i.e. SERVER_NAME is set), we can pregenerate the constant
gravatar default URL once at application startup, and re-use that,
as url_for calls are surprisingly expensive.
Especially on torrent view pages with lots of comments, this cuts down
on url_for calls massively, saving on my system about 0.3 ms per call.
* Use Flask-Assets to minify self-hosted JS files
By having Flask-Assets minify the two JS files we ship, namely
main.js and bootstrap-select.js, we can shave off 28406 bytes.
The minified files are generated on startup. If one wishes to
manually clean them up or build them, they can use the
"flask assets" management command, e.g. "flask assets clean".
* Workaround to fix tests
State carries over in tests, which is the dumbest shit ever. Fix it
by clearing the bundles before setting them.
* 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
