Two tests (end_to_end_different_root and end_to_end_write_csv_file) were using the same temporary CSV file path, causing race conditions during parallel test execution. On riscv64, this manifested as the end_to_end_different_root test consistently failing with CSV contamination from the other test.

Changes

  • Use unique CSV filenames per test to prevent collision:
    • end_to_end_different_root → mlc_test_different_root.csv
    • end_to_end_write_csv_file → mlc_test_write_csv.csv
// Before: both tests used the same path
let csv_output = std::env::temp_dir().join("mlc_test_output.csv");

// After: each test has its own file
let csv_output = std::env::temp_dir().join("mlc_test_different_root.csv");
let csv_output = std::env::temp_dir().join("mlc_test_write_csv.csv");

<issue_title>end_to_end_different_root test fails on riscv64: CSV contains unexpected entries (header only expected)</issue_title>
<issue_description>Describe the bug
The end_to_end_different_root test expects the generated CSV file to contain only the header row (source,line,column,target), but on our riscv64 build the CSV contains three extra lines from benches/benchmark/markdown/ignore_me.md. The test panics on assert_eq!(lines.len(), 1) (left = 4, right = 1).

thread 'end_to_end_different_root' panicked at tests/end_to_end.rs:65:9:
assertion `left == right` failed
  left: 4
 right: 1
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

To Reproduce
Steps to reproduce the behavior:

  1. Clone repo and build on a riscv64 environment (Arch/riscv64 in our case).
  2. cargo test
  3. See error

markuplinkchecker-1.0.0-1-riscv64-check.log

I add println!("CSV file content:\n{}", content); to end_to_end.rs
Expected behavior
When root_dir is set to the test directory benches/different_root, the generated CSV file should contain only the header row (no additional entries), because that test fixture should produce no CSV-recorded broken links.
source,line,column,target

actual behavior

source,line,column,target
benches/benchmark/markdown/ignore_me.md,1,1,broken_Link
benches/benchmark/markdown/ignore_me.md,2,1,broken_Link
benches/benchmark/markdown/ignore_me.md,3,1,broken_Link

This causes the assertion assert_eq!(lines.len(), 1) to fail (4 != 1), test panics and CI fails.

Desktop

  • Platform: riscv64 (Arch Linux riscv64 build environment)
