ÚAbstractDistributiona¦ A base class for handling installable artifacts.
|
|
The requirements for anything installable are as follows:
|
|
- we must be able to determine the requirement name
|
(or we can't correctly handle the non-upgrade case).
|
|
- for packages with setup requirements, we must also be able
|
to determine their requirements without installing additional
|
packages (for the same reason as run-time dependencies)
|
|
- we must be able to create a Distribution object exposing the
|
above metadata.
|
|
- if we need to do work in the build tracker, we must be able to generate a unique
|
string to identify the requirement in the build tracker.
