Jones" +Date: Wed, 25 May 2022 16:47:04 +0100 +Subject: [PATCH] convert: If listing RPM applications fails, rebuild DB and + retry + +In libguestfs before commit 488245ed6c ("daemon: rpm: Check return +values from librpm calls") we didn't bother to check the return values +from any librpm calls. In some cases where the RPM database is +faulty, this caused us to return a zero-length array of applications +(but no error indication). Libguestfs has subsequently been fixed so +now it returns an error if the RPM database is corrupt. + +This commit changes virt-v2v behaviour so that if either +guestfs_inspect_list_applications2 returns a zero-length list (ie. old +libguestfs) or it throws an error (new libguestfs) then we attempt to +rebuild the RPM database and retry the operation. Rebuilding the +database can recover from some but not all RPM DB corruption. + +See-also: https://bugzilla.redhat.com/show_bug.cgi?id=2089623#c12 +Fixes: https://bugzilla.redhat.com/show_bug.cgi?id=2089623 +Reported-by: Xiaodai Wang +Reported-by: Ming Xie +Reviewed-by: Laszlo Ersek +(cherry picked from commit 31bf5db25bcfd8a9f5a48cc0523abae28861de9a) +--- + v2v/inspect_source.ml | 34 ++++++++++++++++++++++++++++++++-- + 1 file changed, 32 insertions(+), 2 deletions(-) + +diff --git a/v2v/inspect_source.ml b/v2v/inspect_source.ml +index b8a3c8ad..554fde1d 100644 +--- a/v2v/inspect_source.ml ++++ b/v2v/inspect_source.ml +@@ -34,6 +34,7 @@ let rec inspect_source root_choice g = + reject_if_not_installed_image g root; + + let typ = g#inspect_get_type root in ++ let package_format = g#inspect_get_package_format root in + + (* Mount up the filesystems. *) + let mps = g#inspect_get_mountpoints root in +@@ -71,7 +72,7 @@ let rec inspect_source root_choice g = + ) mps; + + (* Get list of applications/packages installed. *) +- let apps = g#inspect_list_applications2 root in ++ let apps = list_applications g root package_format in + let apps = Array.to_list apps in + + (* A map of app2_name -> application2, for easier lookups.
