Red Hat Satellite engineering is moving the tracking of its product development work on Satellite to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "Satellite project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs will be migrated starting at the end of May. If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "Satellite project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/SAT-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Eric Helms 2020-07-29 18:46:46 UTC
I would like to be able to detect if there are pending Candlepin database migrations to allow only running the migration task if there are. This helps the Satellite installer be idempotent.

[root@pipeline-upgrade-luna-nightly-centos7 candlepin]# ./cpdb --status --user=candlepin --password W7EkKTcVvT6W654kexPLFCQRNhDeoMxt
Configuring PostgreSQL with JDBC URL: jdbc:postgresql:candlepin
--driver=org.postgresql.Driver --classpath=/var/lib/tomcat/webapps/candlepin/WEB-INF/lib/postgresql-42.2.2.jar:/var/lib/tomcat/webapps/candlepin/WEB-INF/classes/ --url=jdbc:postgresql:candlepin --username=$DBUSERNAME --changeLogFile=db/changelog/changelog-update.xml --password=$DBPASSWORD --logLevel=severe
4 change sets have not been applied to candlepin@jdbc:postgresql:candlepin

     db/changelog/20140408160212-add-pool-source-sub-table.xml::20140408160212-5::ckozak

     db/changelog/20170718095058-purge-orphaned-pools.xml::20170718095058-0::crog
Liquibase 'status' Successful

This would imply there are 4 changesets that need migrated and applied. If I then run 'migrate' I see it try to apply these changesets, mention "skip on failure" in the logs. This implies that this check will never return 0 as there are changsets that attempt to get applied, are skipped and the migration is OK with that.

Upon review of our valid but aging backlog the Satellite Team has concluded that this Bugzilla does not meet the criteria for a resolution in the near term, and are planning to close in a month. This message may be a repeat of a previous update and the bug is again being considered to be closed. If you have any concerns about this, please contact your Red Hat Account team.  Thank you.

Thank you for your interest in Red Hat Satellite. We have evaluated this request, and while we recognize that it is a valid request, we do not expect this to be implemented in the product in the foreseeable future. This is due to other priorities for the product, and not a reflection on the request itself. We are therefore closing this out as WONTFIX. If you have any concerns about this feel free to contact your Red Hat Account Team. Thank you.
