Hi Mathieu,
I can't reproduce this issue.
I ran the related recipetool oe-selftest on Ubuntu 22.04 host, Ubuntu 24.04
host and Fedora 44 container. All succeeded.
To be more detailed, I ran 'oe-selftest -r
recipetool.RecipetoolAppendTests.test_recipetool_appendfile_add_bindir' on
Ubuntu 22 and Fedora 44, and 'oe-selftest -r recipetool' on Ubuntu 24.
I examined the error messages on autobuilder. The key part is:
upstream-stable-release-point.bbclass:18: SyntaxWarning: invalid escape
sequence '\\.'\n return '\\.'.join(stable_parts)\n
However, the actual codes are:
'\.'.join(stable_parts)
There seems to be an extra '\' there. Interestingly, even if I manually added
an extra '\' to the codes, the test ('oe-selftest -r
recipetool.RecipetoolAppendTests.test_recipetool_appendfile_add_bindir) still
passed.
Could you please help me check how to reproduce this issue?
For easier examination, I've copy pasted the autobuilder's error message below.

Hi Chen,
Thanks for the new version.
We got several selftest fails on the autobuilder:

Can you have a look at this issue?
