Subject: [PATCH] generateBuildIDs: Fix error handling.
|
2017-03-10 09:06:03 +00:00
|
|
|
|
|
|
|
|
commit e6bdf7 made it so that we don't give a warning or error message
|
|
|
|
|
for non-kernel ET_REL object files with missing or bad build-ids. But
|
|
|
|
|
we still (unintentionally) failed generateBuildIDs which made us skip
|
|
|
|
|
generating the cpioList causing an obscure failure message.
|
|
|
|
|
|
|
|
|
|
Move the sanity check earlier so we don't process such object files at
|
|
|
|
|
all. And if there is any real error from generateBuildIDs give a clear
|
|
|
|
|
error message and explicitly set processingFailed.
