Subject: [PATCH] gnu: linux-libre-documentation: Fix compilation.
Date: Tue, 13 Feb 2024 17:22:09 +0100

When compiling linux-libre-documentation <at> 6.6.16, the compilation fails with
following error message:

    Exception occurred:
      File "/tmp/guix-build-linux-libre-documentation-6.6.16.drv-0/linux-6.6.16/Documentation/sphinx/kernel_feat.py", line 112, in run
        nodeList = self.nestedParse(out_lines, fname)
    UnboundLocalError: local variable 'fname' referenced before assignment

This is already fixed upstream[0], so this commit backports the change.

+Subject: docs: kernel_feat.py: fix build error for missing files
+
+If the directory passed to the '.. kernel-feat::' directive does not
+exist or the get_feat.pl script does not find any files to extract
+features from, Sphinx will report the following error:
+
+    Sphinx parallel build error:
+    UnboundLocalError: local variable 'fname' referenced before assignment
+    make[2]: *** [Documentation/Makefile:102: htmldocs] Error 2
+
+This is due to how I changed the script in c48a7c44a1d0 ("docs:
+kernel_feat.py: fix potential command injection"). Before that, the
+filename passed along to self.nestedParse() in this case was weirdly
+just the whole get_feat.pl invocation.
+
+We can fix it by doing what kernel_abi.py does -- just pass
+self.arguments[0] as 'fname'.

I see, I guess it was a mistake trying to fetch the patch in this way.  I've
sent a v2 that just adds it into the patches/ directory.  I hope that will work
fine.

Have a nice day,

I double-checked the hash and your original patch had the correct value.

For some reason, when the build farm tried to download the patch file
from the kernel infrastructure, the wrong data was received and the hash
did not match.

But when I downloaded the patch file "by hand" with `curl`, I received
the expected data.

Then, I applied your patch to a checkout of guix.git and successfully
built linux-libre-documentation with `./pre-inst-env [...]`.

So, I think your original patch is good.

Sometimes these transient errors occur. Including the patch directly in
our repo would be more reliable than fetching it, but there is the minor
negative effect of increasing the size of our codebase. I chose to fetch
the data in this case.

Thank you very much for working on this bug!
