GNU coreutils 9.11: Detailed Test report 06/04

[sylvestre]

This catalogues the remaining GNU coreutils 9.11 test-suite failures so they
can be tracked and worked on individually. Totals from the aggregated run:
~690 tests — 625 PASS / 55 FAIL / 9 SKIP / 1 ERROR.

Tests that cannot pass for structural reasons (they intercept glibc calls via
LD_PRELOAD, or drive uutils through gdb breakpoints) are separated into the
INCOMPATIBLE section, since they depend on internal implementation details we
do not match. A few entries are marked (intermittent) — they are listed in
.github/workflows/ignore-intermittent.txt and fail only sporadically.

INCOMPATIBLE Tests

Tests using LD_PRELOAD or gdb breakpoints cannot be fixed without matching
internal implementation details:

• cp/nfs-removal-race.sh (LD_PRELOAD): NFS client removal race during cp S D
• dd/fail-ftruncate-fstat.sh (LD_PRELOAD): dd must stop copying when ftruncate/fstat fail
• df/skip-duplicates.sh (LD_PRELOAD): duplicate mount-list entry injection
• nproc/nproc-quota.sh (LD_PRELOAD): cgroup-quota injection for nproc
• rm/r-root.sh (LD_PRELOAD + gdb): tries to remove / recursively
• rm/rm-readdir-fail.sh (LD_PRELOAD) - PR rm: overriding the libc call when implementation does not match gnu coreutils exactly #9604: simulates readdir failures
• tail/inotify-race.sh (gdb): append-during-initial-read race
• tail/inotify-race2.sh (gdb): file-replaced-during-initial-read race

ERROR Tests

• cp/cp-a-selinux.sh: cp -Z, -a and --preserve=context on a writable NFS partition

cat/splice.sh requires to carch EIO of splice which will never be returned https://man.archlinux.org/man/splice.2.en . I think we should change test suite itself.

[sylvestre]

sounds good, would you like to do it?

[oech3]

I'l talk with GNU instead of patching tests at here.

[oech3]

Ok. Out cat does not have write error: even for read/write code path. It takes many refactoring to fix.

[oech3]

smack-no-root.sh: regressed at #11431 (comment) .
This is CI's issue instead of compatibility issue.

[sylvestre]

Superseded by #13841, which lists only the remaining failures.

[oech3]

note that some LD_PRELOAD is removed at https://github.com/uutils/coreutils/blob/main/util/fetch-gnu.sh

[oech3]

Backporting was actually blocked... #13860
