Message:

Perf dashboard should have UI to retry A/B testing
​https://bugs.webkit.org/show_bug.cgi?id=154090

Reviewed by Chris Dumez.

Added a button to re-try an existing A/B testing group with a custom repetition count. The same button functions
as a way of confirming the progression/regression when there have been no A/B testing scheduled in the task.

Also fixed the bug that A/B testing groups that have been waiting for other test groups will be shown as "running".

  • public/v3/components/results-table.js:

(ResultsTable.cssTemplate): Don't pad the list of extra repositories when it's empty.

  • public/v3/components/test-group-results-table.js:

(TestGroupResultsTable.prototype.buildRowGroups): Use TestGroup.labelForRootSet instead of manually
computing the letter for each configuration set.

  • public/v3/models/build-request.js:

(BuildRequest.prototype.hasStarted): Added.

  • public/v3/models/data-model.js:

(DataModelObject.ensureSingleton): Added.
(DataModelObject.cachedFetch): Added noCache option. This is used when re-fetching the test groups after
creating one.

  • public/v3/models/measurement-cluster.js:

(MeasurementCluster.prototype.startTime): Added.

  • public/v3/models/measurement-set.js:

(MeasurementSet.prototype.hasFetchedRange): Added. Returns true only if there are no "holes" (cluster
yet to be fetched) between the specified time range. This was added to fix a bug in AnalysisTaskPage's
_didFetchMeasurement.

  • public/v3/models/test-group.js:

(TestGroup): Added this._rootSetToLabel.
(TestGroup.prototype.addBuildRequest): Reset this._rootSetToLabel along with this._requestedRootSets.
(TestGroup.prototype.repetitionCount): Added. Returns the number of iterations executed per set. We assume that
every root set in the test group shares a single repetition count.
(TestGroup.prototype.requestedRootSets): Now populates this._rootSetToLabel for labelForRootSet.
(TestGroup.prototype.labelForRootSet): Added.
(TestGroup.prototype.hasStarted): Added.
(TestGroup.prototype.compareTestResults): Use 'running' and 'pending' to differentiate test groups that are waiting
for other groups to finish running from the ones that are actually running ('incomplete' before this patch).
(TestGroup.fetchByTask):
(TestGroup.createAndRefetchTestGroups): Added. Creates a new test group using the privileged-api/create-test-group
and fetches the list of test groups for the specified analysis task.
(TestGroup._createModelsFromFetchedTestGroups): Extracted from TestGroup.fetchByTask.

  • public/v3/pages/analysis-task-page.js:

(AnalysisTaskPage): Initialize _renderedCurrentTestGroup to undefined so that we'd always can differentiate
the initial call to AnalysisTaskPage.render and subsequent calls in which it's identical to _currentTestGroup.
(AnalysisTaskPage.prototype._didFetchMeasurement): Fixed a bug that we don't exit early even when some
clusters in between startPoint and endPoint are still being fetched via newly added hasFetchedRange.
(AnalysisTaskPage.prototype.render): Update the default repetition count based on the current test group.
Also update the label of the button to "Confirm the change" if there is no A/B testing in this task.
(AnalysisTaskPage.prototype._retryCurrentTestGroup): Added. Re-triggers an existing A/B testing group or creates
the A/B testing for the entire range of the analysis task.
(AnalysisTaskPage.prototype._hasDuplicateTestGroupName): Added.
(AnalysisTaskPage.prototype._createRetryNameForTestGroup): Added.
(AnalysisTaskPage.htmlTemplate): Added form controls to re-trigger A/B testing.
(AnalysisTaskPage.cssTemplate): Updated the style.
