The libpod HTTP API path (PodmanClient::create_container) ran manifest
memory_limit values like "128Mi" through parse_memory_limit which
lowercased+trim_end_matches("m"), leaving "128i" which parse::<f64>()
rejected. The resulting None became 0 via .unwrap_or(0), and podman
serialised that into the OCI config as memory.limit:0. At container
start time systemd then rejected MemoryMax=0 with "Value specified in
MemoryMax is out of range".
Silently wrong for every manifest in apps/ that uses Kubernetes-style
suffixes (all of them). Became visible on .228 when Step 9 first
exercised the ProdContainerOrchestrator path for bitcoin-ui and lnd-ui
installs \u2014 the old first-boot-containers.sh bash script used podman
run --memory 128m directly, which podman-the-CLI parses correctly, so
the bug never surfaced before.
Two parts:
- parse_memory_limit now recognises Ki/Mi/Gi/Ti (IEC binary, what k8s
and our manifests use), kB/MB/GB/TB (SI decimal), k/K/m/M/g/G/t/T
(docker shorthand, treated as IEC binary for backwards compat), and
bare byte integers. Filters out zero/negative results.
- create_container omits the memory/cpu fields entirely when the
manifest has no limit or parsing fails, rather than emitting 0. The
libpod API treats absent as unlimited; 0 is "set MemoryMax=0" which
systemd rightly rejects. Defence in depth against the next weird
suffix someone puts in a manifest.
Six regression tests in the new tests module cover IEC, SI, shorthand,
raw bytes, invalid input (empty/garbage/0/negative), and whitespace.
