Subject: [PATCH] inspection: Fix inspection of recent RPM guests using
|
|
|
|
|
non-BDB.
|
|
|
|
|
|
|
|
|
|
Recent RPM-based guests have switched from using Berkeley DB (BDB) to
|
|
|
|
|
sqlite. In order to inspect these guests (and earlier ones) we need
|
|
|
|
|
to stop using the hokey parsing of the BDB and use librpm APIs
|
|
|
|
|
instead.
|
|
|
|
|
|
|
|
|
|
This commit adds a new internal API so we can call librpm from the
|
|
|
|
|
daemon, and changes the library part to use the new API for RPM-based
|
|
|
|
|
guests.
|
|
|
|
|
|
|
|
|
|
This change removes the requirement for BDB tools like db_dump.

|
|
|
|
|
|
|
|
This breaks the virt-inspector test (now in the separate guestfs-tools
|
|
|
|
|
repository). However this is not a bug in libguestfs, but a bug in
|
|
|
|
|
the phoney Fedora guest that we use for testing - we created a
|
|
|
|
|
BDB-style RPM database which was supposed to be just enough to make
|
|
|
|
|
the old code work. The new code using real librpm needs
|
|
|
|
|
/usr/lib/rpm/rpmrc (not present in the phoney image) and also cannot
|
|
|
|
|
parse the phoney database, so we will need to separately rework that
|
|
|
|
|
test.
