Bug 1781763: [release-4.3] proxy: add handler with same ResyncPeriod as shared informer. #81
Conversation
Works around a nasty bug where having multiple handlers with non-homogeneous resync times causes updates during connection disruption to be missed by one or more handlers.

$ oc adm release info quay.io/openshift-release-dev/ocp-release:4.3.0-rc.0-x86_64 | grep Upgrades
Upgrades: 4.2.13
$ oc adm release info quay.io/openshift-release-dev/ocp-release:4.3.0-rc.3-x86_64 | grep Upgrades
Upgrades: 4.2.16, 4.3.0-rc.0, 4.3.0-rc.1, 4.3.0-rc.2
The wide 'from' regexp was appropriate for 4.3.0-rc.0, which had no
4.3 update sources. But rc.3 does have update sources, and we want to
allow 4.3.0-rc.0 -> 4.3.0-rc.3, because it is not impacted by the
4.2->4.3 GCP update bug. The overly-strict regexp was from 6d3db09
(Blocking edges to candidate 4.3.0-rc.3, 2020-01-23, #34).
Also expand the referenced bugs to for the blocked 4.2 -> 4.3 edges:
* Update hangs with [1]:
Working towards 4.3.0...: 13% complete
and machine-config going Degraded=True with RequiredPoolsFailed:
Unable to apply 4.3.0-...: timed out waiting for the condition
during syncRequiredMachineConfigPools: pool master has not
progressed to latest configuration: controller version mismatch
for rendered-master-6c22... expected 23a6... has d780... retrying
Fixed in 4.2 with MCO 31fed93 [2] and in 4.2 with MCO 25bb6ae [3].
$ oc adm release info --commits registry.svc.ci.openshift.org/ocp/release:4.2.14 | grep machine-config
machine-config-operator https://github.com/openshift/machine-config-operator d780d197a9c5848ba786982c0c4aaa7487297046

machine-config-operator https://github.com/openshift/machine-config-operator 31fed93186c9f84708f5cdfd0227ffe4f79b31cd
So the 4.2 fix was in 4.2.16.
$ oc adm release info --commits registry.svc.ci.openshift.org/ocp/release:4.3.0-rc.0 | grep machine-config
machine-config-operator https://github.com/openshift/machine-config-operator 23a6e6fb37e73501bc3216183ef5e6ebb15efc7a

machine-config-operator https://github.com/openshift/machine-config-operator 25bb6aeb58135c38a667e849edf5244871be4992
So the 4.3 fix was new in rc.3.
* Updates hang with FailedCreatePodSandBox events in the
openshift-ingress namespace like [4]:
pod/router-default-...: Failed create pod sandbox: rpc error: code

k8s_router-default-..._openshift-ingress_...(...): Multus: error

Fixed in 4.2 with MCO 9366460 [5] and in 4.3 with MCO 311a01e [6].

So the 4.3 fix was between rc.0's 23a6e6fb37 and rc.3's 25bb6aeb58
(see 'release info' calls in the previous list entry for those
commit hashes).

4.2.18 -> 4.3.1 [16]. This doesn't happen every time though; at
least one 4.2.16 -> 4.3.0-rc.3 has passed on GCP [17]. We don't
have a root-cause yet, but the final failure matches [8] discussed
above.
