# BST-TIMEOUT: 900   # 14 upstream cases under ptest-runner; the runner's 60s default is nowhere near
. "$BST_LIB"

# libexif 0.6.24 (poky recipes-support/libexif) -- the EXIF metadata parser that
# almost every camera-image tool reads through, ported here as a static library
# plus its own upstream test suite, which OpenEmbedded packages as a ptest.
#
# WHAT THIS FILE ASSERTS. The port's acceptance gate is upstream's own suite, run
# on target under ptest-runner exactly as the ticket requires: no interactive
# session, no hand-driven check. run-ptest is `make -o Makefile runtest-TESTS`,
# and runtest-TESTS is not stock automake -- poky patches automake-native
# (buildtest.patch) to split check-TESTS into buildtest-TESTS + runtest-TESTS, and
# ONLY in the serial-tests branch, which is why the recipe carries
# 0001-Add-serial-tests-config-needed-by-ptest.patch. What executes is therefore
# automake's obsolescent SERIAL harness driving the 14 names in TESTS.
#
# WHY THIS SUITE IS WORTH MORE THAN "THE LIBRARY LINKS". Three of the cases are
# byte-comparisons against expectations checked into the tarball, not API smoke:
#   - parse-regression.sh parses nine real camera JPEGs (Canon, Fuji, four
#     Olympus, three Pentax makernote variants) and diffs each against its
#     .parsed file;
#   - swap-byte-order.sh reparses the same nine with the TIFF byte order flipped
#     and demands the same text out, which is a direct check of this arm's
#     endian handling rather than of its syscalls;
#   - extract-parse.sh round-trips each image through test-extract and reparses,
#     and separately cross-checks test-parse against test-parse-from-data.
# Those .parsed files are fixed inputs, identical on every platform, so a single
# disagreement here is a defect on wasm32 rather than a difference to reason
# about.
#
# THE ORACLE IS A NATIVE x86_64 CONTROL of the identical 0.6.24 tarball with the
# identical 4-patch oe series taken from the recipe's own SRC_URI, autoreconf'd
# with OE'S OWN native autotools (the patched automake -- a control built with the
# host's could not run runtest-TESTS at all), configured --disable-shared
# --disable-docs, built out-of-tree like oe's ${B}, and driven through the
# identical `make -o Makefile runtest-TESTS`. It reported 13 PASS + 1 SKIP of 14.
# The per-case expectations below are enumerated rather than reduced to a count,
# because a suite that silently stopped running parse-regression.sh would still
# report a clean zero failures.
