ci: git-fetch-retry composite action (HTTP/1.1 + bounded backoff) - #932
Merged
Conversation
Durable follow-up to the runner-side HTTP/1.1 git config on the self-hosted Linux runners. Wraps git fetch/--unshallow with exponential backoff to absorb the intermittent curl 56 / curl 92 (HTTP/2 stream CANCEL) egress faults that fail actions/checkout on c2pool-linux-198-*. Opt-in; no workflows wired yet.

ci: git-fetch-retry composite action (HTTP/1.1 + bounded backoff)
Durable generalization of the HTTP/1.1 git-config slice that was hand-applied
to Linux runners 198-1/-2/-3 this cycle. Wraps
git fetch/clonein areusable
.github/actions/git-fetch-retrycomposite action that:http.version HTTP/1.1(the curl 56/92 flakes that killed ci: backport arm64 watchdog fixes to Intel runner-watchdog (drop test deferred to .204 access) #924attribution-gate and dash: wire the embedded arm so --run can actually take it (#738) #891 Windows were HTTP/2 egress resets across two hosts)
Additive only: two new files under
.github/actions/git-fetch-retry/(
action.yml+README.md), no existing workflow modified. Wiring thecall-sites is a follow-up once this lands and integrator reviews the action.
Draft — for integrator review. Not for self-merge.
