Raynard Sandwick added the comment: I have opened issue #17318 to try to specify the problem better. While I do think that catalogs are the correct fix for the validation use case (and thus would like to see something more out-of-the-box in that vein), the real trouble is that users are often unaware that they're sending requests to DTD URIs, so some combination of fixes in default behavior and/or documentation is definitely needed.
The external_ges feature does help, in a way, but is poorly communicated to new users, and moreover does not respect the difference between external DTD subsets and external general entities (there's a reason "DOCTYPE" isn't spelled "ENTITY"). The default behavior is not well documented, and the constraining behavior of DTDs is frequently unnecessary. Either a user should have to explicitly enable validation, or it should be irrevocably obvious to a user that validation is the default behavior, and in both cases it should be blatantly documented that validation may cause network side effects. I think the input has been reasonable all around, and yet I find it rather insane that this issue didn't eventually at least result in a documentation fix, thanks to what looks like push-back for push-back's sake, though I will gladly admit the conclusion that it was underspecified is entirely valid. Anyway, further info in the new issue... ---------- nosy: +rsandwick3 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue2124> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
