RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 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 "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". 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 "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-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.

Doc Text:
.The `azure-events-az` resource agent no longer produces an error with Pacemaker 2.1 and later The `azure-events-az` resource agent executes the `crm_simulate -Ls` command and parses the output. With Pacemaker 2.1 and later, the output of the `crm_simulate` command no longer contains the text `Transition Summary:`, which resulted in an error. With this fix, the agent no longer yields an error when this text is missing.

Description Oyvind Albrigtsen 2023-03-28 15:07:16 UTC 
+++ This bug was initially created as a clone of Bug #2181019 +++

Description of problem:
resource-agents package provides azure-events-az agent. This agent executes 'crm_simulate -Ls' and parses output. With pacemaker 2.1 and newer the output of crm_simulate changed and no longer contains text 'Transition Summary:', resulting with an error for azure-events-az.

Version-Release number of selected component (if applicable):
RHEL 8.6 (and newer)
resource-agents-4.9.0-16.el8_6.8.x86_64
pacemaker-cli-2.1.2-4.el8_6.5.x86_64

How reproducible:
Error in azure-events-az only shows after an Azure scheduled event is triggered. Example of such event is VM redeploy or reboot. https://learn.microsoft.com/en-us/azure/virtual-machines/linux/scheduled-events

Errors during execution of azure-events-az, as a monitor within pacemaker or manually with 'export OCF_ROOT=/usr/lib/ocf; export OCF_RESKEY_verbose=1; /usr/lib/ocf/resource.d/heartbeat/azure-events-az monitor' causes an error:

ocf-exit-reason:object of type 'bool' has no len()
ocf.py(None)[2963061]:  Mar 22 21:04:03 ERROR: object of type 'bool' has no len()

Steps to Reproduce:
See above section

Actual results:
Within /usr/lib/ocf/resource.d/heartbeat/azure-events-az, method transitionSummary() on line 296 calls crm_simulate -Ls (line 311). This method expects to find "Transition Summary:" in the output. Upto and including RHEL 8.4 this was true (pacemaker 2.0.5 in RHEL8.4). In pacemaker 2.1.x this line is no longer part of output.

Result is that within azure-events-az, method allResourcesStoppedOnNode(node) then fails in line 372 with above errors


Expected results:
# crm_simulate -Ls
Transition Summary:
	* Promote rsc_SAPHana_HN1_HDB03:0      (Slave -> Master hsr3-db1)
	* Stop    rsc_SAPHana_HN1_HDB03:1      (hsr3-db0)
	* Move    rsc_ip_HN1_HDB03     (Started hsr3-db0 -> hsr3-db1)
	* Start   rsc_nc_HN1_HDB03     (hsr3-db1)
# Excepted result when there are no pending actions:
Transition Summary:

@kgaillot is there a crm_feature_set version I should check against so we can use new format where needed, and fallback to the old way for older versions?

3.7.4, which is also when --output-as=xml is available for crm_simulate

Fix to treat no "Transition Summary" as no actions:https://github.com/ClusterLabs/resource-agents/pull/1854

--output-as=xml is quite new in crm_simulate, so not as backwards compatible.
