If we can assume that there is only data in /usr/share, then we can remove about 330k of the items from our trust database. The files are architecture-independent. We've even been told in the past that noarch Python modules should live in /usr/share. I don't claim to be an expert on FHS, but apparently this is not that simple. https://bugzilla.redhat.com/show_bug.cgi?id=543756 -- Miro Hrončok -- Phone: +420777974800 IRC: mhroncok ___ devel mailing list -- devel@lists.fedoraproject.org To unsubscribe send an email to devel-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org

Right now it takes about 165 MB of virtual memory to hold the database. Binary trees are very efficient in searching, but why search 400k when the items that need to be trusted is really more like 50k. I'm trying to think of time efficient ways of pruning the list. I suppose I can call fnmatch 400k times to keep these python byte code caches, but I suspect they don't really belong there. -Steve ___ devel mailing list -- devel@lists.fedoraproject.org To unsubscribe send an email to devel-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org
