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?
Hello Chen,
I'm not sure why you're not seeing this, but the fix is almost
certainly prefixing the string with r, e.g. making it a raw string.
Oe-core has had lots of similar fixes recently, e.g.:

Hi Alex,
The variable setting has no difference than the similar
UPSTREAM_CHECK_REGEX/GITTAGREGEX.
e.g.,
meta/recipes-multimedia/speex/speexdsp_1.2.1.bb:UPSTREAM_CHECK_REGEX =
"speexdsp-(?P<pver>\d+(\.\d+)+)\.tar"
meta/recipes-multimedia/speex/speex_1.2.1.bb:UPSTREAM_CHECK_REGEX =
"speex-(?P<pver>\d+(\.\d+)+)\.tar"
meta/recipes-multimedia/gstreamer/gst-examples_1.28.2.bb:UPSTREAM_CHECK_GITTAGREGEX
= "^(?P<pver>\d+\.(\d*[02468])+(\.\d+)+)"
meta/recipes-multimedia/libtheora/libtheora_1.2.0.bb:UPSTREAM_CHECK_REGEX
= "libtheora-(?P<pver>\d+(\.\d)+)\.(tar\.gz|tgz)"
In theory, if the UPSTREAM_STABLE_RELEASE_REGEX setting gets a warning,
settings like above should also get warnings. Or am I missing something?
And in Yocto, we can't set variable like this:
VAR1 = r"abc"
This will result in parsing error.
I'm quite confused about this and any help is quite appreciated.
Regards,
Qi
