23-128: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick winAdd a stdin read-error assertion.
The test does not exercise the
io.ReadAllerror branch. It only tests successful stdin reads and named-file open failure.Add a closed
os.Stdincase. Assert that the error containsfailed to read <stdin>. This verifies the behavior documented indocs/release-notes.mdline 22.Proposed test update

I think we just need a Rebase onto main for tmt-tests Otherwise this lgtm |
The stdin read error used infile.Name(), which is "/dev/stdin" on Linux,
instead of the already-computed friendly filename ("<stdin>"). Refactor
input reading into readInput() and report the friendly name on read
failures.
Fixes coreos#2281
Addresses coreos/butane#726

The errcheck linter flags the unchecked Close and Remove calls in the TestReadInput cleanup closures. Surface those errors via the test logger so the cleanup fails loudly instead of being silently dropped. Signed-off-by: Deepak Bhagat <deepak988088@gmail.com>

- Around line 23-136: Extend TestReadInput with a stdin read-error case that
assigns a closed *os.File to os.Stdin, calls readInput with an empty input path,
and asserts the error contains “failed to read <stdin>:”. Preserve proper stdin
restoration and file cleanup, and verify the wrapped error’s filename rather
than relying only on the error being non-nil.

Done — rebased onto main (tmt-tests now clean) and fixed the lint violations in TestReadInput: |

Rebased onto main to clear the merge conflict in docs/release-notes.md (kept both the symlink fix entry from main and this PR's entry). Force-pushed as 7cf336f. |
Add a regression test that assigns a closed *os.File to os.Stdin and calls readInput with an empty input path, asserting the wrapped error contains the friendly <stdin> name. This exercises the io.ReadAll error path that the existing cases did not cover. Signed-off-by: Deepak Bhagat <deepak988088@gmail.com>

When Butane reads from stdin and hits a read error, it prints the OS file name (
/dev/stdinon Linux) instead of the friendly<stdin>label used everywhere else in the error output.This ports the fix into the merged Ignition tree (it came up as coreos/butane#726, fixed in butane PR #728, and now lives under #2281). Input reading is now a
readInputhelper that returns the data, the friendly filename, and any error, so the read failure reports<stdin>consistently with the rest of the report.Added
butane/internal/main_test.gocovering stdin, empty stdin, a file, and a missing file.Fixes #2281
