# BST-TIMEOUT: 1800

# gsl — the GNU Scientific Library, closed on UPSTREAM'S OWN per-module test
# drivers. OpenEmbedded wires no ptest for gsl, so the meta-brintos bbappend
# builds automake's check_PROGRAMS (`make check TESTS=`, which links them and
# runs nothing) and installs the resulting binaries flat under
# ${libexecdir}/gsl-tests, one file per driver, named for its module.
#
# WHY THAT IS THE WHOLE GATE. Each driver is self-contained: its expected values
# are compiled in, it reads no shipped payload, it needs no network peer and no
# TTY, and it prints its own verdict. Between them they make tens of millions of
# floating-point assertions — specfunc 54.8M, linalg 35.4M, bspline 19.1M —
# which makes this the most thorough check of the wasm32-hwjs toolchain's
# floating-point behaviour on the image.
#
# THIS IS ONE SUITE IN TWO FILES, AND THE SPLIT IS A MEASUREMENT, NOT A TASTE.
# Run whole it took 959 s on target (native x86-64: 92 s, so ~10x). The packager
# README sets a suite's declared bound at ~3x its measured time, and
# BST_SUITE_TIMEOUT_MAX caps any marker at 2400 — so a single file could be
# given only 2.5x headroom, at the hard ceiling, with nowhere to go if a loaded
# host slows it. Split by measured cost the two halves are ~460 s and ~410 s,
# each declaring 1800. `--suite 76-gsl` selects BOTH (the selector is a
# substring match), so the ticket gate and the nightly need no change.
# 76-gsl-heavy.test carries the five most expensive drivers and nothing else;
# this file carries the payload assertions and the other 51.
#
# WHAT A CORRECT RUN LOOKS LIKE WAS FIXED NATIVELY BEFORE ANY wasm32 RESULT WAS
# READ: an x86-64 build of the identical 2.7.1 tree runs all 57 drivers to
# `Completed [N/N]` with exit 0. So the verdict in gsl-run.sh is exit 0 AND a
# summary whose two counts are equal — not merely exit 0, and not a substring of
# the output.
#
# $BST_GSL_ROOT prefixes every path so this file can be validated against a
# native /usr-shaped install before it ships. Empty on target, which is the only
# value the image ever sees.
