This commit changes the way search filters are parsed. Instead of
directly appending the data into the search query and creating k:v
pairs, all of the search filters are now a URL parameter. This results
in a clear look overall and hides much of the logic from the end user.
Closes#1969
Simple routes have been moved into a single `Misc` file.
Embed routes have been moved into a single `Embed` file.
The preferences route has been renamed to be more consistent with other parts
of the codebase.
The config file can now be specified with `INVIDIOUS_CONFIG_FILE`.
A YAML formatted string can still be passed with `INVIDIOUS_CONFIG`, replacing
the config file.
Additionally all options can now be specified as environment variables.
The syntax for variable names is `INVIDIOUS_` followed by the option name in
upper case. The values are parsed as YAML.
These new env vars only update the provided main configuration, but it is
possible to point the config file at the example config and then use env vars
for all config options:
```
INVIDIOUS_CONFIG_FILE=./config/config.example.yml \
INVIDIOUS_CHANNEL_THREADS=10 \
./invidious
```
The crystal http client maintains a keepalive connection to the other
server which stays alive for some time. This should be closed if the
client instance is not used again to avoid hogging resources
This is similar to the removed `top-enabled` option but for the Popular feed.
The instance needs to be restarted if the feed was enabled.
Editing admin options on the preferences page is also fixed.
The handling of the feed pages now only happens in a single place.
Instead of redirecting:
- The Top feed now displays a message that it was removed from Invidious.
- The Popular feed now displays a message that it was disabled if it was.
Traces can be enabled with `-l trace`.
The problem with subscriptions is that sometimes requests to YouTube never
finish. As soon as that happens `channel-threads` times subscriptions stop
being refreshed. This is most likely a problem with the lsquick bindings.
