The test code for the hanging case is:
CASE "check base env: set non-existing OCF_RESKEY_statusurl"
Include prepare
Env OCF_RESKEY_statusurl="yoyoyoyo"
AgentRun start OCF_ERR_GENERIC
It looks like the env variable $OCF_RESKEY_statusurl gets used in the script in
the apache_monitor_basic() routine, where it's used as $STATUSURL:
https://github.com/ClusterLabs/resource-
agents/blob/main/heartbeat/apache
I'm not certain how it is causing a hang in this case, but it's used
only by this line:
if ${ourhttpclient}_func "$STATUSURL" | grep -Ei "$TESTREGEX" >
/dev/null # <---
I'm guessing that `ourhttpclient` resolves to wget or curl or something.
Locally, both will error immediately:
stirling: ~/pkg/ResourceAgents/resource-agents-gu$ curl yoyoyoyo
curl: (6) Could not resolve host: yoyoyoyo
stirling: ~/pkg/ResourceAgents/resource-agents-gu$ wget yoyoyoyo
--2024-09-03 13:00:48-- http://yoyoyoyo/
Resolving yoyoyoyo (yoyoyoyo)... failed: Name or service not known.
wget: unable to resolve host address ‘yoyoyoyo’
Is it possible instead of erroring it is hanging, like on a domain
lookup? I could imagine Launchpad's proxy blocking could do that.
It might be informative to do some instrumenting of the routine to see
where exactly it's failing, e.g.:
apache_monitor_basic() {
echo "Attempting to run ${ourhttpclient}_func '$STATUSURL'..."
apache_monitor_basic() {
if ${ourhttpclient}_func "$STATUSURL" | grep -Ei "$TESTREGEX" >
/dev/null # <---
then
echo " ...unexpected success 1 (?!?)"
return $OCF_SUCCESS
fi
attempt_index_monitor_request
if [ $? -eq 0 ]; then
echo " ...unexpected success 2 (?!?)"
return $OCF_SUCCESS
fi
if ! ocf_is_probe; then
echo " ...failed to probe httpd status page"
ocf_exit_reason "Failed to access httpd status page."
fi
echo "...expected error situation"
return $OCF_ERR_GENERIC
}
Honestly, I'm unclear if this test case is not super crucial for us to
run in Ubuntu's Autopkgtest; it is *supposed* to fail, just differently
than how it's failing for us. :-P It might be worth it to simply
disable the test case so the migration can complete, and maybe let
Debian and/or upstream know about the failure?
