* introduce a function checkIfSeriesNeedToBeFixed to scan all value fields in the response and provide a function that updates Series so they can be uniquely identifiable. Only Graphite and TestData are checked.
* update `convertDataFramesToResults` to run this function and provide it to WideToMany
* update WideToMany to run the fix function if it is not nil
* introduce a new node-type ML and implement a command outlier that uses ML plugin as a source of data.
* add feature flag mlExpressions that guards the feature
* add data source uid to QueryError
* add error and datasource uid to tracing
* split queryDataResponseToResults to two functions one to extract frame from the result, and another to convert it
* propagate logger with context to convertDataFramesToResults
* add NodeTypeFromDatasourceUID and DataSourceModelFromNodeType()
* deprecate expr.DataSourceModel
* replace usages of IsDataSource to NodeTypeFromDatasourceUID
* replace usages of DataSourceModel to DataSourceModelFromNodeType()
Takes a specific code path for data that identifies itself as dataplane instead of "guessing" what the data is.
The data must identify itself by being in the dataplane by having both the following frame metadata properties:
- TypeVersion property that is greater than 0.0
- 'Type' property
The flag is disableSSEDataplane and disables this functionality and uses the old code for all queries regardless.
See https://github.com/grafana/grafana-plugin-sdk-go/blob/main/data/contract_docs/contract.md for dataplane details.
This pull request re-applies the refactoring of ConditionsCmd from a
reverted fix#56812 for mathexp.noData. It does not add the fix, or
tests for the fix, because those were added in #56816. We use the
additional test coverage added in #56816 and #58650 to avoid the
reoccurrence of regressions that caused us to revert #56812 the
first time.
Adding support for backend plugin client middlewares. This allows headers in outgoing
backend plugin and HTTP requests to be modified using client middlewares.
The following client middlewares added:
Forward cookies: Will forward incoming HTTP request Cookies to outgoing plugins.Client
and HTTP requests if the datasource has enabled forwarding of cookies (keepCookies).
Forward OAuth token: Will set OAuth token headers on outgoing plugins.Client and HTTP
requests if the datasource has enabled Forward OAuth Identity (oauthPassThru).
Clear auth headers: Will clear any outgoing HTTP headers that was part of the incoming
HTTP request and used when authenticating to Grafana.
The current suggested way to register client middlewares is to have a separate package,
pluginsintegration, responsible for bootstrap/instantiate the backend plugin client with
middlewares and/or longer term bootstrap/instantiate plugin management.

This commit fixes an issue where mathexp.NoData would return an error
in ConditionsCmd (Classic Condition) instead of no data. It further
refactors the Execute method to make it easier to understand.
* create contextual log context provider
* use contextual provider in scheduler
* init logger in the package
* use context for log context
* use context in state manager
* make TimeRange interface and add relative range
* make Execute methods support the current time
* update resample to support relative time range
* update DSNode to support relative time range
* update query service to create queries with absolute time
* make alerting evaluator create relative time ranges
This commit fixes a bug where queries from datasources such as InfluxDB that returned no data would not create a DatasourceNoData alert, but instead an error "can only reduce type series, got type noData".
* 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.

When there is a single frame with no fields (e.g. splunk datasource) SSE errors when trying to figure out the data type. This frame needs to exist since this is where the executedQueryString metadata exists.
This adds a new return type to SSE to represent no data, so the original frame with its metadata can still be maintained.
* update decrypt secrets function signature and add secrets error handling
* remove a couple instances of unnecessary logging since errors are properly handled now
* add unit test
* fix linting issues
