There was a problem hiding this comment.
I made a few changes, but overall looks great!
changes made:
- added a specific DPKG archive metadata type; though it's the same as the DB entry we want to have the flexibility to be able to change one or the other independent of one another. This required a JSON schema update.
- Added licenses extraction from the embedded data.tar.* file
- removed the binary test fixture and used the common container image + pkgtest test harness
- removed io.ReadAll() uses and instead plumped through readers to prevent large chunks of memory being allocated
