New submission from Steve Dower <[email protected]>:
I suspect this is related to the fix for issue30485, but haven't fully debugged
it.
In PC/layout/support/appxmanifest.py, I have code that looks up an existing
element and adds it if missing:
def find_or_add(xml, element, attr=None, always_add=False):
if always_add:
e = None
else:
q = element
if attr:
q += "[@{}='{}']".format(*attr)
e = xml.find(q, APPXMANIFEST_NS)
if e is None:
...
return e
For my 3.8.0a4 build, this started failing to match elements with attributes
included. As a result, I ended up with N elements in a space where the schema
only allows 1, and part of the 3.8.0a4 release is now blocked (okay, it's
unblocked because I manually fixed a file and built the rest by hand, but it
still held things up by a day).
I found that by removing the empty string entry in my namespaces dictionary the
issue is fixed:
APPXMANIFEST_NS = {
#"": "http://schemas.microsoft.com/appx/manifest/foundation/windows10";,
"m": "http://schemas.microsoft.com/appx/manifest/foundation/windows10";,
...
}
So I'm not exactly sure what's going on, but as code that worked fine in
3.8.0a3 and earlier now no longer works, I think we should see whether it was a
deliberate break or accidental. If there's no reason to regress users, I'd
prefer to avoid it.
