📝 Walkthrough

Summary by CodeRabbit

Removed

• Owner and QE owner field values from Jira issue assignees are no longer automatically synchronized to tracker records during Jira tracker downloads.

Walkthrough

Removed Jira assignee-to-owner mapping and related normalization/persistence logic; tests and changelog updated to stop deriving owner and qe_owner from Jira assignees.

Changes

Cohort / File(s)	Summary
Constants collectors/jiraffe/constants.py	Deleted the "assignee": ["owner"] entry from TASK_CHANGELOG_FIELD_MAPPING.
Conversion logic collectors/jiraffe/convertors.py	Removed JiraUserMapping usage and all code that normalized or saved Jira assignee account IDs into owner/qe_owner fields; owner no longer derived or persisted from Jira assignee.
Convertor tests collectors/jiraffe/tests/test_convertors.py	Removed instantiation/import of JiraUserMappingFactory and the assertion that flaw.owner came from the mapping; adjusted mock issue setup accordingly.
Collector tests collectors/jiraffe/tests/test_collectors.py	Removed per-test creation of JiraUserMapping via JiraUserMappingFactory in two VCR tests; other test logic unchanged.
Changelog docs/CHANGELOG.md	Added an Unreleased -> Removed entry documenting removal of owner/qe_owner parsing from Jira tracker download (OSIDB-4875).

Mostly LGTM.

The syncing of the owner was also removed for the task convertor but I think this is fine since we no longer sync tasks from Jira to OSIDB. Could another @RedHatProductSecurity/osidb-devs confirm this?

There are also a few more places in the tests that can be cleaned up:

osidb/collectors/jiraffe/tests/test_collectors.py

Line 125 in 4d142ef

JiraUserMappingFactory(atlassian_cloud_id="test-cloud-id")

osidb/collectors/jiraffe/tests/test_collectors.py

Line 571 in 4d142ef

JiraUserMappingFactory(atlassian_cloud_id="test-cloud-id")

osidb/collectors/jiraffe/tests/test_convertors.py

Lines 394 to 395 in 4d142ef

	mock_issue.fields.assignee = None
	mock_issue.fields.customfield_12316243 = None

@Jincxz, addressed all the cleanup suggestions. Thanks for the review!

[Jincxz]

LGTM. Thank you for addressing my comments!

[JakubFrejlach]

I agree with @Jincxz that the collector is disabled in ops, but we have a scope mismatch here. OSIDB-4875 and the changelog specifically address trackers, yet this PR modifies tasks as well.

We should either:

• Update the Jira issue and changelog to explicitly include task owner removal.
• Revert the changes to task owners to keep this PR strictly about trackers.

Otherwise, we're introducing a 'silent' breaking change for tasks that isn't documented anywhere.

[svelamak]

Good catch! As the task collector is disabled in ops, keeping the change. Will update the changelog and Jira ticket explicitly mention the task owner removal as well.

Thank you for addressing my points! LGTM now, just squash commits a bit please.
