Coreutils Perl Test Failure Summary

[moogchi]

Description

Full log is on branch perl-test-log

lind-wasm-apps/coreutils/perl_test.log

Current Failures without fix

rust panic

count: 1
first_seen_line: 2881
example: thread 'lind-fork-15' (281805) panicked at /home/lind/lind-wasm/src/wasmtime/crates/lind-multi-process/src/lib.rs:1489:50:
test_blocks: misc/wc-files0-from

exec-ed module error

count: 1
first_seen_line: 2882
example: exec-ed module error: failed to run main module
test_blocks: misc/wc-files0-from

wasm trap

count: 1
first_seen_line: 2886
example: 1: wasm trap: indirect call type mismatch
test_blocks: misc/wc-files0-from

Current Failures with fix (Ill work on it)

argv[0] Path Prefix Mismatch (Skippable)

Affected: du/files0-from, misc/basename, misc/comm, misc/cut, misc/dirname, misc/dircolors, misc/expr, misc/factor, misc/fmt, misc/join, misc/md5sum, misc/mktemp, misc/paste, misc/printf-cov, mv/i-1

Coreutils.pm uses system $cmd_str (string form), which perl passes to /bin/sh -c. Shell resolves bare binary names to full paths before exec, so argv[0] becomes /bin/cut instead of cut, causing error message mismatches. Tools are functioning correctly — failure is cosmetic.
actual: /bin/cut: fields and positions are numbered from 1
expected: cut: fields and positions are numbered from 1

Missing pr Test Data

Affected: pr/pr-tests

Test expects pre-generated reference files (/pr/0Fnt, /pr/FFn, etc.) inside the sandbox that are not present. abs_srcdir is also unset.
Use of uninitialized value $ENV{"abs_srcdir"}
/bin/sh: /pr/0Fnt: No such file or directory

---

Fixed

Floating Point Returns NAN

Affected: misc/seq, misc/printf-cov

Floating point format specifiers and seq produce NAN instead of correct values.
printf %F → NAN (expected: 1.000000)
printf %E → NAN (expected: 2.000000E+00)
seq 10 → (empty) (expected: 1..10)

execve Bad Address

Affected: misc/cut, misc/join (specific subtests)

A bad pointer is passed to execve for certain test cases — distinct from the earlier "No such file" error.
Can't exec "/bin/sh": Bad address at /tests/Coreutils.pm line 478.

Cage ID Panic

Affected: pr/pr-tests

The pr test suite spawns many subprocesses and exhausts the cage ID pool, causing a runtime panic.
Cage ID is outside of valid range
cage.rs:277

for 1.

Fix at the Coreutils.pm level — patch the test harness to strip the path prefix from actual output before comparing:

In the comparison, normalize /bin/foo → foo in actual output

$actual =~ s|/bin/(\w+):|$1:|g;

For 5:
(Missing pr test data): Straightforward — the test data files weren't copied into lindfs. The pr tests need their reference files. Fix:

cp -r ~/lind-wasm/lind-wasm-apps/coreutils/tests/pr ~/lind-wasm/lindfs/tests/

And abs_srcdir needs to be set in the test environment — it should point to /tests or wherever the test data lives inside the sandbox.
