fix: add TTL to soft tx validation cache for relay node mempool cleanup (#737)#748
Merged
Conversation
…up (#737) * fix: add TTL to soft tx validation cache to evict stale entries on relay nodes The soft validation cache only had time-to-idle (TTI), which resets on every access. On relay nodes (non-block-producers), pool revalidation continuously accesses cached entries, preventing TTI expiry. Since relay nodes never call do_validate_guaranteed_execution (block authoring only), the soft cache is never explicitly invalidated either — causing invalid transactions to persist in the mempool indefinitely. Adding a 60-second time-to-live (TTL) ensures entries are unconditionally evicted, forcing a fresh apply() check against current ledger state on the next revalidation cycle. JIRA: PM-21787 * chore: add change file for soft cache TTL fix * fix: upgrade eslint and fix lint errors to resolve npm audit high vulnerabilities Upgrade eslint (^4.0.0 → ^9.29.0), typescript-eslint (^7.3.1 → ^8.33.0), and minimatch override (10.1.2 → 10.2.1) to resolve all 11 high severity npm audit vulnerabilities. Fix switch fallthrough bug in run.ts and suppress no-require-imports in standalone JS worker script.

Overview
Rebase of #737
The soft validation cache only had time-to-idle (TTI), which resets on
every access. On relay nodes (non-block-producers), pool revalidation
continuously accesses cached entries, preventing TTI expiry. Since relay
nodes never call do_validate_guaranteed_execution (block authoring only),
the soft cache is never explicitly invalidated either — causing invalid
transactions to persist in the mempool indefinitely.
Adding a 60-second time-to-live (TTL) ensures entries are unconditionally
evicted, forcing a fresh apply() check against current ledger state on
the next revalidation cycle.
