/**
|
|
* This module contains the function to install plugins
|
|
* or check if the uploaded file is an update for a plugin.
|
|
*
|
|
* When user uploads a file with .zip extension(neccessary requirement)
|
|
* steps that should perform:
|
|
* --> Check if the file type is .zip.
|
|
* --> Extract it to a temp folder.
|
|
* --> Check for the .info file. If not exists throw error
|
|
* --> Extract the information from the .info file.
|
|
* --> Check for the plugin name already exists or not.
|
|
* --> if Plugin Name exists it compare the version of .info and version of plugin stored in db.
|
|
* --> if same throw error and if different it checks for UpdateInfo field in .info file.
|
|
* --> if UpdateInfo not found throw error.
|
|
* --> if UpdateInfo found add the update to the ryzom_ams_lib.updates table.
|
|
* --> if it's not an update and plugin with same name already exists throw error.
|
|
* --> if plugin with same name not present provide option to install plugin
