- The util/converter Prometheus response json parse was not checking for errors while parsing. It now does. In particular, if `[dataproxy]/response_limit` is set in Grafana's config, it will now recognize the limit error.
- Fixes#73747
- Adds `jsonitere` package, which wraps json-iterator/go's Iterator's Methods with methods that return errors, so errcheck linting can be relied upon
- Impact:
- If something was sending malformed JSON to the prometheus or loki datasources, the previous code might have accepted that and partially processed the data
- Before there may have been partial data with no error, where as no there may be errors but they will have no partial results, just the error.
* WIP
* Set public_suffix to a pre Ruby 2.6 version
* we don't need to install python
* Stretch->Buster
* Bump versions in lib.star
* Manually update linter
Sort of messy, but the .mod-file need to contain all dependencies that
use 1.16+ features, otherwise they're assumed to be compiled with
-lang=go1.16 and cannot access generics et al.
Bingo doesn't seem to understand that, but it's possible to manually
update things to get Bingo happy.
* undo reformatting
* Various lint improvements
* More from the linter
* goimports -w ./pkg/
* Disable gocritic
* Add/modify linter exceptions
* lint + flatten nested list
Go 1.19 doesn't support nested lists, and there wasn't an obvious workaround.
