Hi Paul, That is a good point and I will look for this. Thanks for the advice!
I also working on a tool that tries checking (and suggest updates) to a given list of URLs: bad links, different cases of redirections, replacing http by https, etc. This exercice was first to go over, Paul, your nice list here: https://wiki.debian.org/PaulWise/InterestingSoftware (here including duplicate cases) But then I used it to check the source package homepages in UDD. And why not later may be the watch file URL!? Sure I need such large set to look at all the possible cases and avoid too many false positives and distinguish between minor one (like http://nowhere.org to http://www.nowhere.org/en/index.html) and major one. Moreover, the tool need also to suggest an URL for source package that does not have one or a broken one. And for instance Repology (https://repology.org/) may be an interesting resource to look for that. I know that there is DUCK but the current result of my tool does not agree with the results displayed by DUCK regarding at least the homepages. My tool is running on all the Sid entries in UDD. Also http://duck.debian.net/sourcepackages.txt is empty, is this a bug? Regarding 'Watch file checker' in Wiki Page of the Debian QA Group, it is just an indirect link to the uscan manpage. Is this ok? Well, how could I consider a contribution to Debian if this should be the case? Report a bug to each source packages after a human check from my side (if not to many!)? Working on DUCK? Improve lintian / lintian-brush? ... Regards, Patrice
