The same (namespace, label, node) is asked up to three times per affected pod across the sections of this script. That was free while the first call hung forever and the script died inside it; with a per-read bound each repeat costs its own timeout, and against a wedged apiserver the repetition becomes the largest consumer of the caller's envelope -- enough that a 300s budget buys two pods where it could buy five. Answers are memoised, empty ones included: "there is no cilium-agent on this node" is exactly the lookup worth not repeating. The memo is a file rather than a variable, which is not a style choice. The walk over affected pods runs on the right-hand side of a pipeline, so it executes in a subshell and a variable memo is discarded at the end of it, leaving every lookup to be paid for again in the sections that follow. With the variable form the suite still recorded each of the three lookups twice. That is also why this is not the shape of the node memo above it, which is a space-delimited string matched with a case glob and is correct for a dedup living entirely inside the walk. Keys are compared as whole tab-separated fields, so the '=' inside a label selector is ordinary payload; what the scheme rests on is that no namespace, label selector or node name contains a tab, which Kubernetes names and selectors cannot. An empty pod list is also separated from one that never answered, so the branch below it stops reporting a failed read as a cluster with nothing wrong. Pinned by a stub that records every per-node lookup it is given: the test fails if any is issued twice. Assisted-By: Claude <noreply@anthropic.com> Signed-off-by: Aleksei Sviridkin <f@lex.la>
