Merge lp:~mabac/linaro-image-tools/bug-638384-hwpackforceyes-unneeded into lp:linaro-image-tools/11.11

[Mattias Backman]

Hi,

This branch makes --hwpack-force-yes implied if signatures for hwpacks are passed and verification is ok.

It will only bypass the package signature checking for those hwpacks which have ok signatures passed.

The behaviour for binary-sig is not changed yet.

Thanks,

Mattias

Use os.path.basename() instead of split().

The existing code seems to cause the script to abort when the sha1sum check of any hwpack fails, but after this change I think such a failure wouldn't cause the script to abort. Is this intentional?

I think that cmd_runner makes the script abort when the return code of
sha1sums is > 0. So I think that I can remove the check from the call
to gpg also since it aborts anyway. I couldn't decide whether to do
that or leave it in to make it clear that the intention is to abort
when the verification fails. But then I should do something similar
for sha1sums to be consistent, I guess.

[Guilherme Salgado (salgado)]

You're right, Mattias. I'd forgotten about that. I think we should do the same for the gpg check indeed, as that code will never be executed because cmd_runner.run() will raise an exception in wait() when the return code of the subprocess is non-zero, which means the print and sys.exit() calls can never be executed.

review: Approve

Remove message and exit that can never be reached.
