What’s the behavior if it’s set, but to the empty string? bitbake only checks whether it equals "1" or not. Without this patch, an empty string is the same as not set since it doesn't equal to "1". But if it is set to "0", bitbake uses it as enable network, sanity.bbclass uses it as disable netowrk, which are conflicted. We can add checking for empty string, but do we have to ? Limit it to "0" or "1" makes things clear. IMO if we’re going to change the semantics, we should do it in bitbake and then mirror that in the metadata. Sanity checking should mirror the actual variable behavior where it’s used. Sounds reasonable, but I'm not sure how to do it, ways I can think out: 1) Handle "0" as enable network as bitbake does in sanity.bbclass 2) If we want to limit its values, maybe we need check it in bitbake rather than in sanity.bbclass, there are also other values have the similar problems, I did a rough grep, such as BB_FETCH_PREMIRRORONLY: fetch2/__init__.py: premirroronly = (self.d.getVar("BB_FETCH_PREMIRRORONLY", True) == "1") fetch2/git.py: if d.getVar("BB_FETCH_PREMIRRORONLY", True) is not None: The __init__.py only checks whether it is "1" or not, but git.py checks if it is None, there would be confusions when it is "" or "0". Sounds like bb.utils.to_boolean() may be our friend for a number of these.
Thanks, sounds good to me, let's see others comments, and I will work on that later if no objections (maybe 1 month later). Currently I will simply make sanity.bbclass handle "0" as bitbake does. Have good day. I have to go to sleep now. // Robert
