Bug 412301 – app-shells/zsh[static] - $USERNAME is not available

• Status: RESOLVED OBSOLETE

Hi,

when zsh was compiled with static USE flag being enabled the $USERNAME variable is not available:

@cobalt:~> echo $SHELL $ZSH_VERSION 
/bin/zsh 4.3.17
@cobalt:~> echo $USERNAME

@cobalt:~> export USERNAME="$(whoami)"
@cobalt:~> echo $USERNAME             

@cobalt:~> echo $PS1
%n@%m:%~> 
@cobalt:~>


As you can see, %n in my prompt doesn't get expanded as well as it's using the USERNAME variable.

I've tested this with zsh-4.3.15 and zsh-4.3.17 both on a stable x86 and amd64 machine.

I just got told that one cannot assign a value to the USERNAME variable. So the test case can be reduced to this:


@cobalt:~> echo $SHELL $ZSH_VERSION 
/bin/zsh 4.3.17
@cobalt:~> echo $USERNAME

@cobalt:~> echo $PS1
%n@%m:%~> 
@cobalt:~>


On a dynamically linked zsh USERNAME is not empty:

lars@shanghai:~> echo $SHELL $ZSH_VERSION
/bin/zsh 4.3.17
lars@shanghai:~> echo $USERNAME
lars
lars@shanghai:~> echo $PS1     
%n@%m:%~> 
lars@shanghai:~>

and thus %n gets expanded in the prompt.

might be a bug in glibc ...

This is no longer issue with current zsh in tree.
