coreutils-9.2: Failing tests on Adélie Linux |
|

Hello,
While updating coreutils to 9.2 on Adélie Linux, I’ve run into a few
interesting corner-cases in the test suite. As a note, our distribution
is using musl as the libc.
1. `tests/misc/csplit-heap.sh` fails when /bin/sh is Bash
I actually saw this on 9.1 as well, but I only saw it on one system and
considered it a fluke since our auto builder infrastructure didn’t see
the issue. Seeing it again in 9.2 made me look deeper, and it turns out
that when /bin/sh is a symlink to /bin/bash, the test fails with:
./tests/misc/csplit-heap.sh: xmalloc: cannot allocate 16085 bytes
When /bin/sh is a symlink to /bin/dash, the test no longer fails.
However:
2. `tests/misc/tee.sh` fails when /bin/sh is Dash and `make` is run
under Zsh
When running the test suite from my default Zsh environment, and when
/bin/sh is a symlink to /bin/dash, I receive an error when running the
tee test.
If:
- /bin/sh is a symlink to /bin/bash; OR if
- /bin/sh is a symlink to /bin/dash, and
- make is launched from a Bash or Dash shell, *not* a Zsh shell,
Then the test passes.
Both test runs with the respective failures have generated useful log
files, which are attached. I don’t know if this is actually a bug in
the coreutils test suite, or if the bugs perhaps lie in the shells.
Best,
-A.

The attached should fix that issue.
Confirmed, this patch fixed it - thank you!
2. `tests/misc/tee.sh` fails when /bin/sh is Dash and `make` is run
under Zsh
When running the test suite from my default Zsh environment, and when
/bin/sh is a symlink to /bin/dash, I receive an error when running the
tee test.
If:
- /bin/sh is a symlink to /bin/bash; OR if
- /bin/sh is a symlink to /bin/dash, and
- make is launched from a Bash or Dash shell, *not* a Zsh shell,
Then the test passes.
This is failing as `yes >fifo` is getting EINTR on your shell.
I'm not too sure why that's happening, but it might be
due to interactions on the fifo from the previous part of the test.
Does the following change avoid the problem for you?
cheers,

This also fixed the Zsh issue, indeed.
Thanks for the detailed report and retesting.
Pushed those fixes.
Marking this as done.
