Bug report

Bug description:

5 tests failed:
test_filecmp test_os test_pathlib test_shutil test_tarfile

I tried to build python 3.14.2 in Linux Mint. I downloaded the package .tar.xz

I extracted the content of the package

I ran in the Linux Mint Terminal:

cd Downloads
cd Python-3.14.2
./configure
make
make test

And there appeared the failures of the test mentioned above.

The README.rst file suggests to file a bug report given these issues, so this is the bug report.

CPython versions tested on:

3.14

Operating systems tested on:

Linux

[StanFromIreland]

Can you please run the tests in verbose mode (./python -m test TEST-NAME -v) and post the output? Based on the tests I would presume a filesystem permissions error or the like.

[Hurled3574]

i don't know exactly which outputs to show in the response to your question. these are the outputs that i chose to show, the error messages and the final results.

cd Downloads
cd Python-3.14.2

./python -m test test_filecmp -v

If you need more info or more results, comment me and i will print more info. i don't know if these are the outputs you meant...

Updated your comment to use a code block to make the output more readable.

Most of the tests failed due to:

• File name too long limits;
• Low timestamp resolution on mtime;
• Symbolic link failures;
• Splice or range read.

I suspect you are running the tests on a non-standard filesystem, such as ExFAT, an NFS/Samba mount, or an eCryptfs-encrypted directory.

Can you show which filesystem you were using for this directory?
