Simple patch to avoid unitialized warning and log what we'll do.

Style: elsewhere this file seems to use cuddled elses:

	} elsif (...) {

Or more simply, would it make sense to wrap both 'defined' checks into
a single "if", like so?

		if (defined $entry->{$check} && defined $query->{$check}) {
			...
		} else {
			log_debug(...);
		}

Thanks and hope that helps,
Jonathan

I didn't realize it was a requirement, must I?

Ah, thanks, I missed that.

I prefer the explicit version because we can issue a more precise
log_debug message.

Yes, this is a requirement. See Documentation/SubmittingPatches
to read what signing off actually means here.

See Documentation/SubmittingPatches, section '(5) Sign your work'
for what this means.

If you just forgot to sign off, that's fine and I can forge it or go
without.  If you are unable to sign off because you don't have the
right to submit the change under an open source license, I'd be a bit
worried going forward.

That's fine with me.

After this patch, the code looks like

	if (!defined $entry->{$check}) {
		log_debug(...);
	} elsif (defined $query->{$check}) {
		...
	} else {
		log_debug(...);
	}

As a small nit, wouldn't it be more readable with the two !defined()
cases together?

	if (!defined $entry->{$check}) {
		...
	} elsif (!defined $query->{$check}) {
		...
	} else {
		...
	}

Thanks again.
Jonathan

OK, I didn't realize it was.  Thanks for explaining.

Right, I got it.  Sorry, I didn't know that applied to trivial patches.

Because of way the "next ENTRY" line comes out, I like my way slightly
better, but honestly it's fine either way :)  If you like, go ahead and
commit the rewrite the way it works for you, I have no objections at all.
