Hello,
First please take my apologize for writing such a broad ticket. But
others, with more intel, I asked, didn't.
This is related to a (6 year old) Debian bug ticket:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=926074
In short: The modified date is ignored by the server.
The Debian folks telling me that Django is somehow involved and there
should go a bug ticket and fix.
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=926074#10
I can not tell because I lack of deeper understanding of the underlying
technology.
I do have minimal working example demonstrating the problem with the
Debian server.
>>> url = 'https://tracker.debian.org/pkg/feedparser/rss'
>>> import feedparser as fp
>>> a = fp.parse(url)
>>> import json
>>> print(json.dumps(a.headers, indent=4))
{
"X-Clacks-Overhead": "GNU Terry Pratchett",
"X-Xss-Protection": "1",
"Transfer-Encoding": "chunked",
"Last-Modified": "Sat, 30 Mar 2019 13:06:51 GMT",
"Public-Key-Pins": "pin-
sha256=\"M9Wyk2x6hLne/VkyJWFx33+LB8s+kAaMbO49fnm5fEY=\"; pin-
sha256=\"ZsBWn0bekrum/1CJtBlg5yZ2eqRywN6YwGeBS31nH+s=\"; max-age=5184000",
"Strict-Transport-Security": "max-age=15552000",
"Content-Type": "application/rss+xml; charset=utf-8",
"X-Content-Type-Options": "nosniff",
"Connection": "close",
"Referrer-Policy": "same-origin",
"Content-Encoding": "gzip",
"X-Frame-Options": "sameorigin",
"Server": "Apache",
"Vary": "Cookie,Accept-Encoding",
"Date": "Sun, 31 Mar 2019 11:11:03 GMT"
}
>>> a.modified
'Sat, 30 Mar 2019 13:06:51 GMT'
>>> b = fp.parse(url, modified=a.modified)
>>> len(a.entries)
30
>>> len(b.entries)
30
I would expect "b.entries" should be (near) 0.
I also can not tell wich version of Django is used by Debian.
Maybe you can give some comments in the Debian ticket?
Regards,
Christian
