fix(pnpm-install): skip swap setup on ARM64 runners#276
Merged
Conversation
`pierotofy/set-swap-space@v1.0` runs:
SWAP_FILE=$(swapon --show=NAME | tail -n 1)
sudo swapoff $SWAP_FILE
On ARM64 GitHub runners (`ubuntu-22.04-arm64`, `ubuntu-22.04-N-core-arm64`,
etc.) there is no pre-allocated swap, so `swapon --show` returns empty,
`SWAP_FILE` is empty, and `swapoff` exits with `bad usage` (exit 16).
Every job using this composite action then fails before pnpm install
even runs.
x86_64 runners ship with an existing swap file, so the action works there.
Skip the swap step on ARM64; install runs fine with the runner's default
memory (apify-core's monorepo uses ~30 GB RAM ARM64 boxes). x86_64
behaviour is unchanged.
Discovered while migrating apify/apify-core to pnpm. The full CI suite
runs on ARM64 there, so every job in apify-core PRs that uses this action
fails on the swap step.

If only Claude didn't drop such a massive comment block to say "arm64 runners don't have swap but they have plenty of ram" xD |

Pretty much any workflow on an ARM64 runner that does
uses: apify/workflows/pnpm-install@main. Hit this while migrating apify/apify-core to pnpm — its entire CI suite uses ARM64 boxes, so every job in the migration PR was red on the same swap step.Failure log on ARM64:

Skip the swap step when
runner.arch == 'ARM64'. x86_64 runners ship with an existing swap file so the action keeps working there. ARM64 runners typically have plenty of memory (apify-core CI uses 30 GB ARM64 boxes); not adding 10 GB of swap is fine.
