[sbidoul]

locale.getdefaultlocale() is deprecated in python 3.11. Use getlocale() instead.

@simahawk @gurneyalex would you like to have a look at this little one?

While looking at this I noticed this get_environment() function is called repeatedly (notably each time the registry is built), and it does potentially costly subprocess calls (git, bzr, lsb_release). So I took the opportunity to cache it.

While looking at this I noticed this get_environment() function is called repeatedly (notably each time the registry is built), and it does potentially costly subprocess calls (git, bzr, lsb_release). So I took the opportunity to cache it.

AFAIK, get_server_environment is called only by the model server.config that has, In my opinion nothing to do in this module. It allows to see configuration parameter in a view of a transient model.

1. this feature can be usefull without the module server_environment installed.
2. something may be wrong in this part of the code, if you notice that calls are made regularly. (this should not be the case).
3. this feature can provide security issues.

So I'm in favor to move all that part (server.config + system_info.py) in a dedicated module named server_configuration_visualisation (or something like this).

What do you think ?

Note : this code didn't changed since the creation (version 6.1 : https://github.com/OCA/server-tools/blob/6.1/server_environment/system_info.py)
