ci: use BB_HASHSERVE=auto fallback for fork PRs - #16627

Conversation
OE-core master now enables OEEquivHash by default in the distro config. Setting BB_SIGNATURE_HANDLER=OEBasicHash in local.conf cannot override this (distro config takes precedence). Without a valid BB_HASHSERVE, bitbake tries to use a local sqlite DB at SSTATE_DIR which fails on the NFS-mounted /sstate-cache: ERROR: Hash equivalency database location (BB_HASHSERVE_DB_DIR) cannot be on a NFS mount Fix: use BB_HASHSERVE="auto" as fallback for fork PRs. This starts a local in-memory hash equivalency server within bitbake, satisfying the OEEquivHash requirement without needing network access or a writable non-NFS filesystem. - Internal PRs: BB_HASHSERVE=<remote server> (shared sstate) - Fork PRs: BB_HASHSERVE=auto (local, no sharing but functional)

Problem
OE-core master now enables
OEEquivHashat the distro level (not just local.conf). Previous fix attempts:BB_SIGNATURE_HANDLER = "OEBasicHash"→ doesn't override distro-level configBB_HASHSERVE→ bitbake defaults to local sqlite DB atSSTATE_DIRwhich fails on NFSResult:
Fix
Use
BB_HASHSERVE = "auto"as the fallback. This tells bitbake to start a local in-memory hash equivalency server within the process itself — no NFS DB, no network dependency, no external server needed.hashserv-<release>.internal:8686autoBoth always use
BB_SIGNATURE_HANDLER = "OEEquivHash"since the distro mandates it.Unblocks #16292.
