However, in some runs the condition: + + abs(corr[tau] / sigma) > max_allowed_sigma + +is triggered, resulting in intermittent failures. + +This behavior appears to be highly sensitive to small variations in +floating point calculations and runtime conditions such as CPU timing, +entropy state, and execution environment. The test can pass or fail +without any functional issue in rand() itself. + +This was reproduced by enabling debug output in randtest and running +it multiple times, where occasional failures were observed despite +normal statistical characteristics of the output. + +Since the underlying functionality appears correct and the failure is +environment-dependent, this test behaves similarly to other +nondeterministic tests (e.g., time, timeout) already skipped in this recipe. + +As a temporary measure, disable randtest in ptest to ensure stable +test results in CI environments. + +Upstream discussion: (add link once reported) + +Signed-off-by: Aditya GS +--- + meta/recipes-extended/gawk/gawk_5.4.0.bb | 4 ++++ + 1 file changed, 4 insertions(+) + +diff --git a/meta/recipes-extended/gawk/gawk_5.4.0.bb b/meta/recipes-extended/gawk/gawk_5.4.0.bb +index d7211f28f3..a357d172eb 100644 +--- a/meta/recipes-extended/gawk/gawk_5.4.0.bb ++++ b/meta/recipes-extended/gawk/gawk_5.4.0.bb +@@ -83,6 +83,10 @@ do_install_ptest() { + for t in time timeout; do + echo $t >> ${D}${PTEST_PATH}/test/skipped.txt + done ++ ++rm -f ${D}${PTEST_PATH}/test/randtest.* ++echo randtest >> ${D}${PTEST_PATH}/test/skipped.txt ++ + } + + do_install_ptest:append:libc-musl() { +-- +2.34.1 + diff --git a/meta/recipes-extended/gawk/gawk_5.4.0.bb b/meta/recipes-extended/gawk/gawk_5.4.0.bb index d7211f28f3..71e7ddb31f 100644 --- a/meta/recipes-extended/gawk/gawk_5.4.0.bb +++ b/meta/recipes-extended/gawk/gawk_5.4.0.bb @@ -28,6 +28,7 @@ PACKAGECONFIG[pma-if-64bit] = "--enable-pma,--disable-pma, " SRC_URI = "${GNU_MIRROR}/gawk/gawk-${PV}.tar.xz \ file://run-ptest \ file://0001-configure.ac-re-enable-disabled-printf-features.patch \ + file://randtest-fix.patch \ " SRC_URI[sha256sum] = "3dd430f0cd3b4428c6c3f6afc021b9cd3c1f8c93f7a688dc268ca428a90b4ac1"
