GNU coreutils 9.9: Detailed Test report 01/20 #10390
Description
GNU coreutils Test Coverage Tracking
Failing GNU tests as of 2026-01-20 | Test Coverage Dashboard
Overview
With the number of failing tests now small enough to track individually, this document provides detailed descriptions of each remaining test failure and the next steps needed to achieve full GNU compatibility. Theres a bunch of duplicate PR's for the same tests in the PR queue now and I'm hoping this will allow us to consolidate our efforts.
I am also hoping to separate the tests that are incompatible because they either intercept glibc calls or call gdb on specific lines of source code since we are unable to fix those tests and it wouldn't be good to track compatibility of those tests.

INCOMPATIBLE
Tests that use LD_PRELOAD to intercept glibc calls or gdb breakpoints. If we don't use the same internal calls, we will have to patch these tests.
df/skip-duplicates.sh (LD_PRELOAD)
GNU Test | Intercepts glibc to inject duplicate mount entries
nproc/nproc-quota.sh (LD_PRELOAD)
GNU Test | Intercepts glibc to simulate CPU quota
rm/r-root.sh (LD_PRELOAD + gdb)
GNU Test | Uses gdb breakpoints and LD_PRELOAD for safety net
rm/rm-readdir-fail.sh (LD_PRELOAD) - PR #9604
GNU Test | Intercepts readdir to simulate failures
PR #9604 wraps libc calls to handle LD_PRELOAD tests.
tail/inotify-race.sh (gdb) - PR #9908
GNU Test | Uses gdb breakpoints to trigger race conditions
PR #9908 patches the test to use Rust gdb breakpoints (breaking on watcher_rx.watch_with_parent in watch.rs).
tail/inotify-race2.sh (gdb) - PR #9908
GNU Test | Uses gdb breakpoints to trigger race conditions
PR #9908 patches the test to use Rust gdb breakpoints (breaking on watcher_rx.watch_with_parent in watch.rs).
ERROR
[ ] misc/usage_vs_getopt.sh - PR #9869
GNU Test | Usage message consistency with getopt
The coreutils multicall binary doesn't use clap for argument parsing, so unrecognized options like --unknown were outputting "function/utility not found" instead of "unrecognized option". PR #9869 fixes this by detecting option-like arguments.
