Bug ID: 29022 Summary: 000-permissions files cause problems for backups Product: elfutils Version: unspecified Status: UNCONFIRMED Severity: normal Priority: P2 Component: debuginfod Assignee: unassigned at sourceware dot org Reporter: bugzilla at hadess dot net CC: elfutils-devel at sourceware dot org Target Milestone: --- the debuginfod-client creates 000-permissions files as a way to mark "negative caching". Unfortunately, that causes permissions problems for backup software, disk usage checkers, etc. that rely on being able to access the user's own files. Given that the usage of those 000-permission files is not even atomic (see commit 7d64173fb11c66284a408e52d41d15b7755d65d2), is there any reason not to use the contents of the file, or the name of the file, or some other attribute like the xattrs as a way to carry that "negative cache" information? My backup software's log is hundreds of lines of: Warning: /home/hadess/.var/app/org.gnome.Totem.Devel/cache/debuginfod_client/d9ebf6de9e98f66a21daca59c8f601a9daa03c5b/debuginfo: open: [Errno 13] Permission denied: '/home/hadess/.var/app/org.gnome.Totem.Devel/cache/debuginfod_client/d9ebf6de9e98f66a21daca59c8f601a9daa03c5b/debuginfo' -- You are receiving this mail because: You are on the CC list for the bug.
