[Libguestfs] [PATCH RFC 0/5] Subject: [PATCH RFC 0/5] qapi: Add feature flags to enum members
PATCH 1+2 add feature flags to enum members. Awkward due to an
introspection design mistake; see PATCH 1 for details. Feedback
welcome, in particular from management application guys.
PATCH 3+4 implement policy deprecated-input={reject,crash} for enum
values.
Policy deprecated-output=hide is not implemented, because we can't
hide a value without hiding the entire member, which is almost
certainly more than the requester of this policy bargained for.
Perhaps we want a new policy deprecated-output=crash to help us catch
unwanted use of deprecated enum values. Thoughts?
PATCH 5 puts the new feature flags to use. It makes sense only on top
of Vladimir's deprecation of drive-backup. See its commit message for
a reference.
Based on my "[PATCH 00/22] qapi: Remove simple unions from the schema
language".
Based-on: Message-Id: <20210913123932.3306639-1-armbru(a)redhat.com>
