Control: severity -1 wishlist
Hi, 2016-01-23 20:55 Oleksandr Gavenko:
I have Debian and Kali origins. Kali based on Debian stable. So Kali follow Debian package naming schema but differ in version numbers. They also respect Debian version numbering. So it is possible to make queries to list difference between Debian and Kali with "aptitude search". For example to find command packages with same version: $ aptitude search '?narrow(?origin(Kali),?origin(Debian))' ... To find packages that in Kali but not in Debian: $ aptitude search '?origin(Kali),!?origin(Debian)' ... I would like to find packages that have newer version in Kali than in Debian. Docs: https://www.debian.org/doc/manuals/aptitude/ch02s04s05.html say nothing about direct version comparing. Some indirect comparing possible via ?upgradable and setting priorities in debootstrap'ed environment and chrooting and installing packages. '?narrow' is equal operator for package version. I need a strict greater operator: aptitude search '?gt(?origin(Kali),?origin(Debian))' - any package version that greater. Origins of my question come from (Russian text): http://permalink.gmane.org/gmane.linux.debian.user.russian/123271
I think that indeed the way to get this list of newer packages Kali than in Debian is using ?upgradable, if pinning of the repositories (man apt_preferences) is done correctly and if Kali's versions indeed show higher numbers than Debian. Is this not working properly? Another way to get such a list would be to produce a list of packages and versions of both Kali an Debian, and post-process it using "dpkg --compare-versions". In general, I don't know if the requested operator is very useful, because aptitude and apt have different concept of how the system should work, based on apt pinning. Packages in Debian experimental or unstable might have bigger version numbers than the ones in testing or stable, but still the ones in testing and stable used by default, because the user prefers to maintain most packages in the stable or testing version. So "?upgradable" and other terms are more complex carry more meaning than a simple "greather-than" comparison, and I think that it should be that way. And if it's just for that comparison, "dpkg --compare-versions" is the authoritative source anyway, with its nuances when comparing alphanumeric strings with symbols. Cheers. -- Manuel A.
