* feat: template data source option current by uid
* fix: e2e with explicit uid for "slow-prometheus"
* revert: unrelated change
* revert: unreverted the actually related change
* chore: e2e support for testing ${variable:text}
* fix: use `:raw` instead of `:value` in e2e dashboard
* Alerting: Repurpose rule testing endpoint to return potential alerts
This feature replaces the existing no-longer in-use grafana ruler testing API endpoint /api/v1/rule/test/grafana. The new endpoint returns a list of potential alerts created by the given alert rule, including built-in + interpolated labels and annotations.
The key priority of this endpoint is that it is intended to be as true as possible to what would be generated by the ruler except that the resulting alerts are not filtered to only Resolved / Firing and ready to be sent.
This means that the endpoint will, among other things:
- Attach static annotations and labels from the rule configuration to the alert instances.
- Attach dynamic annotations from the datasource to the alert instances.
- Attach built-in labels and annotations created by the Grafana Ruler (such as alertname and grafana_folder) to the alert instances.
- Interpolate templated annotations / labels and accept allowed template functions.
* Alerting: Fix unique violation when updating rule group with title chains/cycles
The uniqueness constraint for titles within an org+folder is enforced on every update within a transaction instead of on commit (deferred constraint). This means that there could be a set of updates that will throw a unique constraint violation in an intermediate step even though the final state is valid. For example, a chain of updates RuleA -> RuleB -> RuleC could fail if not executed in the correct order, or a swap of titles RuleA <-> RuleB cannot be executed in any order without violating the constraint.
The exact solution to this is complex and requires determining directed paths and cycles in the update graph, adding in temporary updates to break cycles, and then executing the updates in reverse topological order (see first commit in PR if curious).
This is not implemented here.
Instead, we choose a simpler solution that works in all cases but might perform more updates than necessary. This simpler solution makes a determination of whether an intermediate collision could occur and if so, adds a temporary title on all updated rules to break any cycles and remove the need for specific ordering.
In addition, we make sure diffs are executed in the following order: DELETES, UPDATES, INSERTS.
* remove infer type functionality because usability tests confirmed it was confusing/not helpful
* persist button option to open modal when typing in metric select
* update copy desc for setting that includes type and description in search
* when filtering by type, only return metrics with defined type
* give focused metric row more contrast, consistent with metric select focused option
* allow selection of metrics with unknown types and undefined types
* add highlighting to backend search
* augment counters created from summaries with (summary)
* remove type from search input setting and only search by name and description
* fix test to reflect that type has been removed from the metadata input search as duplicated by the filter
* add button to select metric, change wording, make table hover row consistent with grafana table
* add tooltip icon with docs link for metric types that are augmented, histogram and summary
* remove files slated for future refactoring
* style changes based on catherine's review
* remove border from settings btn, select btn increase to md, change col size in table, fix responsive inputs ui for sm screens
* use custom name from legend
* revert prometheus change
* fix issue in the transformer and not prometheus
* getFrameDisplayName falls back to getFieldDisplayName already
* run prettier
* make breaking changes note more prominent in whats new
* changed paragraph structure and added heading
* moved breaking changes section to after the template
* move deprecations to breaking changes page
* break up paragraph
* run prettier
* Update dependency @testing-library/dom to v9.3.0
* dedupe versions in the lockfile
