Summary0002920: Possibility to run a post install script

After installing an extension, it should be possible to run a script/executable.

Convention could be that:

  • during the installation process
  • after the tgz is extracted
  • if a file matching </path/to/extensionname/post-install-scripts.(sh|bat)> exists
  • notify the user [possibility to hide the dialog if other install]
  • run the script

If installing extension from python, it should be possible to pass a flag preventing such popup from appearing.

What trigger the creation of this issue are the pull requests associated with the DTI* extensions - See

What Adrien and I reported in this thread is not necessary anymore since the rpath issue has been addressed since then. However, it might still be a good thing to be able to run scripts post installation in certain cases.

I discussed this with Davide earlier today, a possible design could be:

After installation, execute a python script defined as "post_install_script" in the extension metadata.


post_install_script: the name of the script would be relative the "share" folder of the extension.

Script execution

Should we run code in the 'if name == "main"' section ?

Should we lookup a function named "post_install_setup(extension_directory)" ?

or ... ?

Sandboxed execution in the Extension installation directory ? Discarded: Downloaded code is assumed to be trusted.

Testing of the script

Diffing the setting before and after execution ?
