Subject:    [OE-core] [PATCH v2] buildhistory: Label packages providing per-file dependencies in depends.dot
From:       "Andres Beltran" <abeltran () linux ! microsoft ! com>
Date:       2021-08-30 22:53:03
Message-ID: 20210830225303.19407-1-abeltran () linux ! microsoft ! com
[Download RAW message or body]

Currently, depends.dot includes per-file dependencies but not the packages
providing those files. This makes it hard to obtain all package
dependencies by just looking at depends.dot.

Parse the RPROVIDES and FILERPROVIDES fields from pkgdata to map each of
their values to the package providing the component. Include runtime
packages as dependencies in depends.dot, together with the component
provided by the package as a label.
