It would be nice to have pubDate elements in the news.rss20.xml of PTS to allow
better sorting of items aggregated from multiple packages' feeds. The attached
patch adds more detailed date information to items in news.xml and transforms
them into pubDate elements in the RSS items.
Regards
Jan

Subject: add pubDate to package RSS feeds
Author: Jan Dittberner <ja...@debian.org>
Description: This patch adds a pubDate element to item elements in the RSS
feeds for package's news and fixes deprecation warnings.
* common.py: use hashlib.md5 instead of the md5 module
* update_news.py:
- use subprocess.Popen instead of deprecated os.popen3 for mhonarc
invocation
- use the xml.dom.minidom implementation included in Python since 2.0
- add timestamp_to_rfc822date(timestamp) to convert the timestamp format of
news filenames to RFC 822 timestamps
- generate a new attribute rfc822date in news.xml item elements
* news2rss.xsl: add transformation from rfc822date attribute in news.xml to
pubDate element in RSS
