oh sorry, yes you are right, we need talk in a polite manner, since we are humans

sylvestre · 2026-06-30T07:19:04Z

also, please ping me only when the testsuite is green and there are tests

46 benchmarks were skipped, so the baseline results were used instead. If they were deleted from the codebase, click here and archive them to remove them from the performance reports. ↩

Added tests to check behavior with long path components.

GNU testsuite comparison:

Skip an intermittent issue tests/misc/io-errors (fails in this run but passes in the 'main' branch)
Skip an intermittent issue tests/tail/retry (fails in this run but passes in the 'main' branch)
Skip an intermittent issue tests/tail/symlink (fails in this run but passes in the 'main' branch)
Skipping an intermittent issue tests/cut/bounded-memory (passes in this run but fails in the 'main' branch)

Hi, @sylvestre

now all tests passed and added tests and fix working, can you merge? i appreciate it or still

sylvestre · 2026-06-30T10:27:18Z

 const OPT_RELATIVE_TO: &str = "relative-to";
 const OPT_RELATIVE_BASE: &str = "relative-base";
-
+const MAX_PATH: usize = 255;


seems low, no ?

HackingRepo · 2026-06-30T11:23:33Z

after i restore the tests, they failing that was weird, i just added the max limit then failed, i will see why

HackingRepo · 2026-06-30T11:24:23Z

about soomething different not about realpath at all, it causing issues

HackingRepo · 2026-06-30T13:49:07Z

the 1 failing last job, is about install unrelated fully to the pr, realpath is the thing we fixed, not install that just some problems occurs with CI/CD sometimes, ci/cd race issues sometime tests successed, however the important tests passed and only 1 job failing that happen in tons of prs. but however only 1 failing not a huge problem

HackingRepo · 2026-07-01T06:13:40Z

Hi, @sylvestre

i appreciate it, when you have time, can you please review it again all tests passes, the 1 failing is unrelated to the pr and restored previous tests and ignored rsplit to cspell not fails and now passed, can you review and merge?

sylvestre · 2026-07-01T09:35:07Z

+            .to_str()
+            .is_some_and(|name| name.len() > MAX_PATH)
+    }) {
+        return Err(Error::new(ErrorKind::InvalidInput, "File name too long"));


please use the translate! macro here

ok i will do

HackingRepo · 2026-07-01T17:15:17Z

hi, @sylvestre review now. i added translate! no breaking change, or logic change, so what do you think, i appreciate it, when having time
