Cached MD5 sums

Cached MD5 sums

[Detlef Vollmann]

Hello,

while trying to build a number of packages, I now got twice
errors about MD5 sums.  Even after a new download bitbake
still complained and insisted that some MD5 sum is required
of which I have no idea where it comes from (definitely
not from the accompanying .md5 file in DL_DIR, which
contained the correct MD5 sum).

So I assume that bitbake has in its cache some old MD5 sums
from broken downloads, but I have no idea how to delete those.

Any ideas?

We had a similar problem when the sources resided in an nfs mount.
Is this the case with your sourse/md5 files ?

If yes you need to have statd running on *both* client and server machines
In debian/ubuntu just install the nfs-common package and it solves the issue

Interesing hint.
I don't have an NFS mount now.  But I'm inside of a chroot environment
and previously had an NFS mount from outside the chroot into
inside (on the same machine and even the same physical filesystem).
But I got locking problems and decided to move the DL_DIR into
the chroot.  But probably there's still some wrong info in
the cache, but it still complains about not being able to lock,
though a can lock on exactly the same file inside the same chroot
using my own test program.  I had to hack bitbake (remove the
locking) to get around this).

For real NFS mount from one machine to the other I never had
problems, and probably I should do just that and start completely
fresh...

Thanks again,
