[Libguestfs] [PATCH] builder: when not checking sigs, ignore --fingerprint args (RHBZ#1193237)

When the user chooses to not verify the signatures on the indexes (using --no-check-signature), there is no point in requiring as many --fingerprint as --source (or even just one), as they will not be used anyway. In this case just ignore all the values of the specified --fingerprint arguments. --- builder/cmdline.ml | 19 ++++++++++++------- 1 file changed, 12 insertions(+), 7 deletions(-) diff --git a/builder/cmdline.ml b/builder/cmdline.ml index 9dad141..b8227cc 100644 --- a/builder/cmdline.ml +++ b/builder/cmdline.ml @@ -281,13 +281,18 @@ read the man page virt-builder(1). let nr_sources = List.length sources in let fingerprints = - match fingerprints with - | [fingerprint] -> - (* You're allowed to have multiple sources and one fingerprint: it - * means that the same fingerprint is used for all sources. - *) - repeat fingerprint nr_sources - | xs -> xs in + if check_signature then ( + match fingerprints with + | [fingerprint] -> + (* You're allowed to have multiple sources and one fingerprint: it + * means that the same fingerprint is used for all sources. + *) + repeat fingerprint nr_sources + | xs -> xs + ) else + (* We are not checking signatures, so just ignore any fingerprint + * specified. *) + repeat "" nr_sources in if List.length fingerprints <> nr_sources then error (f_"source and fingerprint lists are not the same length"); -- 2.1.4
