# Reorder input lines (one per test or per shard) so the longest-running
# tests/shards start first under "make check" parallel scheduling. The trick
# is to prefix matched names with a fake duration (100), sort numerically
# descending, then strip the prefix. Slow-matched tests therefore come ahead
# of all unmatched tests; ordering within each group is unspecified.
#
# Why this matters: gnu_parallel hands out jobs in input order. If a slow
# test starts only after most others have finished, the run is bottlenecked
# on its tail. Front-loading slow tests overlaps them with the bulk of
# faster ones for much better wall-clock time.
#
# Maintenance:
#   1) Run `make check` so LOG is up-to-date.
#   2) Run `make suggest-slow-tests` to see candidate slow binaries.
#   3) Add binaries with high per-shard time (slow critical path) or high
#      total time across many shards (need early queueing for fan-out).
# Each alternative is wrapped in `^.*NAME.*$$` so the *whole input line* is
# captured into $$1; then `s,(...),100 $$1,` prepends "100 " to the line.
#
# Tiers below are based on observed timings (see suggest-slow-tests).
# Tier 1: max single-shard time >= 30s (critical-path bottlenecks).
# Tier 2: max single-shard time 15-30s.
# Tier 3: huge total time across many tiny shards; front-loading them keeps
#         the tail of the run busy while big shards finish.

# RocksDB writes object files to the same $(OBJ_DIR) paths regardless of

# COERCE_CONTEXT_SWITCH, etc.  Most of those are applied in this Makefile after
# `include make_config.mk` and are therefore NOT reflected in make_config.mk,
# so switching them and rebuilding silently mixes incompatible object files.
# To guard against that, we hash the fully-resolved compile/link parameters
# (which already embed make_config.mk via PLATFORM_*) and compare against the
# value recorded from the previous build.  On mismatch the build stops so the
# user can `make clean`.  Knobs:
#   AUTO_CLEAN=1
#     run `make clean-rocks` automatically on mismatch
#   ALLOW_BUILD_PARAMETER_CHANGE=1
#     skip the check entirely (e.g. intentionally mixing DEBUG_LEVEL=1 and
