Cherry picked from ui overhaul branch with a few modifications:
- channel folder is renamed to channels
- parsing for channel home and featured channels are removed due to
lack of infrastructure from other commits
(cherry picked from commit 44d18b8e147b47ad06a54cc6fd08423d9f39074d)
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.
Everything that gets logged now has a log level associated with it.
The log level can be set with the new `-l` or `--log-level` arguments.
The defaul log level is `debug` for now. There aren't many things that get
logged but if the logs get spammed in the future it can be set down to `info`.
Since no new tags are created for releases the version has been frozen for some
time, with only the commit hash changing.
Versions based on the latest commit date make it much easier to identify them.
Error handling has been reworked to always go through the new `error_template`,
`error_json` and `error_atom` macros.
They all accept a status code followed by a string message or an exception
object. `error_json` accepts a hash with additional fields as third argument.
If the second argument is an exception a backtrace will be printed, if it is a
string only the string is printed. Since up till now only the exception message
was printed a new `InfoException` class was added for situations where no
backtrace is intended but a string cannot be used.
`error_template` with a string message automatically localizes the message.
Missing error translations have been collected in https://github.com/iv-org/invidious/issues/1497
`error_json` with a string message does not localize the message. This is the
same as previous behavior. If translations are desired for `error_json` they
can be added easily but those error messages have not been collected yet.
Uncaught exceptions previously only printed a generic message ("Looks like
you've found a bug in Invidious. [...]"). They still print that message
but now also include a backtrace.
Try to read app config from the "INVIDIOUS_CONFIG" environment variable.
If the variable is undefined, read config from config.yml file as before.
