what's that?

We have to make a choice, error message from the Windows builds that are now failing cuz I need to update them as well:

XML_GE (for general entities) must be defined, non-empty, either 1 or 0 (0 to disable, 1 to enable; 1 is a common default

You should probably update the default value in line 3719 as well.

what's that?

@ambv "GE" is short for general entities. The flag is documented in detail athttps://libexpat.github.io/doc/api/latest/#XML_GE .

@sethmlarson I would have expected (meaning considered likely) a new line#define XML_GE 1 to go intoCPython's ownexpat_config.h. Did you avoid that file on purpose? Its siblingXML_DTD seems to live there.

You should probably update the default value in line 3719 as well.

For anyone else wondering where (or what the line content is), that seems to be:

@hartwork Thank you for this, I don't know how but mygrep XML_DTD turned up no results. That's definitely where it should go.

@sethmlarson could it be that this removal is accidental?

PS: Here's the Dockerfile that made me spot this, based on earlier version#98742 (review):

@hugovk It feels like now we have to automate this diff comparison. Do you have any good ideas on when to trigger the workflow smartly?

@corona10 did you mean me or@hugovk?

To automate this, you'd need to extract an old and a new version from the diff between the push HEAD and the base commit and so on. I'm not sure if Expat releases are frequent enough to build automation like that and keep it working.

Pull request#100539 is about something related but different, but maybe still of interest to you.

@corona10 PS: maybe a cheap version to cover the core need (unless misunderstood) would be to make CI assert that that file still includes filepyexpatns.h using grep? That would be orders of magnitude simpler 😃

Thanks for catching this, I've updated my commit to not remove these lines.

@hartwork
I meant@hugovk since he has good insight into automation workflow in CPython.
But in any case, the link you introduced looks cool to me, I think that it would be worth to take a look at :)
