Handle deleted packages

[simonegaffurini]

Steps:

• Install hello-world in a temporary package
• Delete its content and the package itself
• Run trm list

The package is still shown.

Possible solution:

If the package was installed (from STMS origin same system)

• Get the packages from ZTRM_INSTALLDEVC
• Check that all of the packages still exist and they are part of the same hierarchy
• Check that all the content of the TADIR transport exist and that they are contained in the root or one of its subpackages

If the package was published (trkorr inside ZTRM_SRC_TRKORR)

• Get the transport root package
• Check that the transport root package exists on the system, if it does, get its subpackages
• Check that all of the content of the TADIR transport still exist in the system and that they are contained in the root or one of its subpackages
