Kyle Brandt	38603b1a9e	Prometheus: Check for errors on json response parsing (#73788) ... - 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.	2 years ago

Emil Tullstedt	b287047052	Chore: Upgrade Go to 1.19.1 (#54902) ... * 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. https://go.dev/doc/comment#lists	3 years ago
