[Robert Ancell <robert.ancell@xxxxxxxxxxxxx>]

** Description changed:

- In file session-child.c in function session_child_run() variable
- `locale_var_names` contains explicit list of locale environment
- variables to inherit. This list lacks of some LC_* variables: LC_PAPER,
- LC_NAME, LC_ADDRESS, LC_TELEPHONE, LC_MEASUREMENT and LC_IDENTIFICATION.
- As a result, these variables are not inherited by child session.
- Therefore, processes inside desktop session set these variables to the
- value of LANG, instead of appropriate values configured in
- /etc/locale.conf.
+ [Impact]
+ Not all system locale variables are passed to sessions.
  
- $ more /etc/locale.conf 
- LANG=en_US.UTF-8
- LC_CTYPE=pl_PL.UTF-8
- LC_NUMERIC=pl_PL.UTF-8
- LC_TIME=pl_PL.UTF-8
- LC_COLLATE=pl_PL.UTF-8
- LC_MONETARY=pl_PL.UTF-8
- LC_MESSAGES=en_US.UTF-8
- LC_PAPER=pl_PL.UTF-8
- LC_NAME=pl_PL.UTF-8
- LC_ADDRESS=pl_PL.UTF-8
- LC_TELEPHONE=pl_PL.UTF-8
- LC_MEASUREMENT=pl_PL.UTF-8
- LC_IDENTIFICATION=pl_PL.UTF-8
- LC_ALL=
+ [Test Case]
+ 1. Edit /etc/locale.conf and set LC_PAPER to a particular value
+ 2. Start LightDM
+ 3. Log into a session
  
- Inside desktop session:
+ Expected result:
+ LC_PAPER is set to the value in /etc/locale.conf
  
- $ locale
- LANG=en_US.utf8
- LC_CTYPE=pl_PL.UTF-8
- LC_NUMERIC=pl_PL.UTF-8
- LC_TIME=pl_PL.UTF-8
- LC_COLLATE=pl_PL.UTF-8
- LC_MONETARY=pl_PL.UTF-8
- LC_MESSAGES=en_US.UTF-8
- LC_PAPER="en_US.utf8"
- LC_NAME="en_US.utf8"
- LC_ADDRESS="en_US.utf8"
- LC_TELEPHONE="en_US.utf8"
- LC_MEASUREMENT="en_US.utf8"
- LC_IDENTIFICATION="en_US.utf8"
- LC_ALL=
+ Observed result:
+ LC_PAPER is not set.
  
- Notice wrong values of LC_PAPER, LC_NAME, LC_ADDRESS, LC_TELEPHONE,
- LC_MEASUREMENT and LC_IDENTIFICATION (en_US.utf8 instead pl_PL.UTF-8).
- 
- Fix:
- 
- Add LC_PAPER, LC_NAME, LC_ADDRESS, LC_TELEPHONE, LC_MEASUREMENT and
- LC_IDENTIFICATION  to the `locale_var_names` array in file session-
- child.c.
+ [Regression potential]
+ Low. We just added to an existing list of LC_* variables that are passed through to sessions.
