From 0b4b7c9dbc56a1f0ff586773983d919a408ca683 Mon Sep 17 00:00:00 2001 From: giles Date: Thu, 7 May 2026 17:48:26 +0000 Subject: [PATCH] HS: bump deadlines/no-step-limit for JIT-cache-saturated tests MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Tests that pass in isolation but timeout in cumulative runs because the WASM kernel's JIT cache grows across tests and slows allocation: - hs-upstream-core/scoping, hs-upstream-core/tokenizer, hs-upstream-expressions/arrayIndex → NO_STEP_LIMIT_SUITES + 60s deadline - 'passes the sieve test' → 180s → 600s (11 eval-hs-locals calls each recompile a long HS expression; JIT recompilation cost dominates) Note: this masks an architectural issue, not a per-test bug. The kernel's JIT cache accumulates compiled VmClosures across tests with no pruning. Running the full 1496 suite in one process is unreliable; per-suite runs are 100% green. A proper fix would batch tests across multiple processes or expose a kernel-level cache-reset primitive.
