cli-tests: levels.sh --max test fails on systems with < 10GB RAM
The compression/levels.sh cli-test unconditionally runs zstd --max on
64-bit systems, which allocates ~8.5GB. This fails on systems with less
than 10GB RAM (e.g. virtual machines, CI containers, embedded test
environments).
The test already handles the 32-bit case by skipping --max:
if echo "$version_info" | grep -q '32-bit'; then
# skip --max test: not enough address space
cp file-19.zst file-max.zst A similar check for available memory would allow the rest of the test
(default levels, clamping, environment variables) to run on
memory-constrained systems:
if echo "$version_info" | grep -q '32-bit' || [ "$(awk '/MemTotal/{print $2}' /proc/meminfo)" -lt 10000000 ]; then
# skip --max test: not enough address space or memory (<10GB)
