Merge request for enabling MDIS to uninstall previous MDIS installation (!348) · Merge requests · Project / 13 / 13MDIS / Linux / 13MD05-90

Jose Javier Rodriguez Barbarin requested to merge 331-mdis-installation-does-not-clear-previous-installations into mad-dev Sep 15, 2023

For enabling MDIS to uninstall previous MDIS installation, MDIS compilation system will create a new text file (saved in /etc/mdis/) called mdis_manifest.mnf that will keep tracking of all MDIS artifacts (binaries, libraries, modules, DESC files, etc...) installed, thus, the compilation infrastructure will be able to remove all previous files installed just reading the manifest file.

Below, an example of the content of a manifest file:

If a previous MDIS version is installed, just try to uninstall previous version, then, install the new version:

user@local:~/workspace/MDIS/manifest$ sudo make install
[sudo] password for user:

....

Invoking uninstall target explicitly:

user@local:~/workspace/MDIS/manifest$ sudo make uninstall
Uninstalling previous MDIS installation...
Updating module dependencies after uninstalling MDIS modules
Updating library cache
===================================
=> MDIS successfully uninstalled <=
===================================

If we invoke uninstall again, when no MDIS version is installed, nothing happens:

user@local:~/workspace/MDIS/manifest$ sudo make uninstall
MDIS is not installed in the system
