control: severity -1 wishlist thanks This behavior was not much of real problem but how this happens was a bit of mastery for me. Here is what I found out. https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=615807
If any kind of search term normalization is in place, search result shouldn't have output such as: Package: mC with capital C. It turned out that search with "dpkg-query -s" is case insensitive. For example $ dpkg-query -s dpkG Package: dpkg Essential: yes Status: install ok installed Priority: required ... While, search with "dpkg-query -l" is case insensitive. For example $ dpkg-query -l dpkG dpkg-query: no packages found matching dpkG These are used internally in dpkg-www in /usr/lib/cgi-bin/dpkg to generate a web page. If single package is passed, it uses "dpkg-query -s" via listPackage(). If multiple packages or glob are passed, these inputs use "dpkg-query -l" via listPackages() and filter its output with listFilter. I think if anyone care to fix the original bug report issue to be addressed, it may be simplest and cleanest to change behavior of "dpkg-query -s" to be case sensitive. This is somewhat intrusive major change for basic tool such as dpkg-query, though. Then invalid search term with upper case will not be matched and things will be consistent. Of course issuing warning for upper case input may be useful for dpkg-www but this is not important. Regards, Osamu
