passing query through grafana variable doesn't work anymore

[jenneron]

Our use case is to restrict table with some label, but also provide an option to append another query or search field from user input.

For example, we can match _AUDIT_LOGINUID:* *

But we can't set $query to * and match _AUDIT_LOGINUID:* $query:

I believe this is due to escape characters in resulting expression: expr:"_AUDIT_LOGINUID:* \"*\""

While this might be sufficient to provide a search field, it makes a wrong expression when the variable is empty: expr:"_AUDIT_LOGINUID:* \"\""

It works when downgrading the plugin to 0.3.0:

The resulting query with 0.3.0: expr:"_AUDIT_LOGINUID:* *"

The resulting query with 0.3.0 and empty variable: expr:"_AUDIT_LOGINUID:* "

Same here. Couldn't get it to work, good its a known issue.

BTW, victorialogs and this datasource are amazing.

Variables are correctly substituted starting from v0.6.0. Closing this issue as done. Feel free to re-open if problem still exists.

@Loori-R @dima-vm please do the follow-ups on related tickets when making a release similarly to how we recommend it here https://docs.victoriametrics.com/contributing:

waiting for release label is assigned to issues that required code changes and those changes were merged to upstream, but not released yet. Once a release is made, maintainers go through all labeled issues, leave a comment about the new release, remove the label, and close the issue.
