rpm -qf directory

[Maxim Yanchenko]

Hi,

I'm seeing a problem with executing "rpm -qf <directory>" (rpm 4.11.3)
When I do strace on that command and watch stat() calls, it shows very
different behavior depending on what I'm querying for.

If I do "rpm -qf /opt/pkg/mylib/1.100" it does exactly one stat() on the
directory I requested.
If I do "rpm -qf /opt/pkg/mylib/1.100/lib" it calls stat() on ALL
directories registered in the rpmdb, no matter if they exist or not.This is
a huge problem when you have a lot of packages installed: when the former
query takes 0.03s, the latter can take up to 2 seconds.
If I do "rpm -qf /opt/pkg/mylib/1.100/lib/libxxx.so" it calls stat() on all
directories registered in the rpmdb matching the path
/opt/pkg/mylib/*/lib/libxxx.so, which is of course better than stat()-ing
everything installed, but still not ideal.

Is it a known issue?
If it's a known bug, is it fixed in later versions?
Are there any known workarounds for rpm 4.11.3 (as it's a system version so
I'm stuck with it in the office)?
Maybe there is a patch that could be applied to 4.11.3 without a full
upgrade (so I could convince our admins to apply it)?

Thanks,
Maxim
