Subject: [PATCH] basic/env-util: drop the validation when deserializing
|
|
environment
|
|
|
|
The environment variables we've serialized can quite possibly contain
|
|
characters outside the set allowed by env_assignment_is_valid(). In
|
|
fact, my environment seems to contain a couple of these:
|
|
|
|
* TERMCAP set by screen contains a '\x7f' character
|
|
* BASH_FUNC_module%% variable has a '%' character in name
|
|
|
|
Strict check of environment variables name and value certainly makes sense for
|
|
unit files, but not so much for deserialization of values we already had
|
|
in our environment.
|
|
|
|
(cherry picked from commit ea43bdd1d7c14e3695a4cc081e4ef4f964160dc1)
