#20373 extra_env_vars for system_binary Issue created by ubmarco Is your feature request related to a problem? Please describe. I want to use

drawio

as a

system_binary

. It crashes with

SIGSEGV

and other errors if the following environment variables are not given:

DISPLAY

,

HOME

,

DBUS_SESSION_BUS_ADDRESS

. When pants runs the fingerprinting step, it invokes the binary with a cleared environment. There is currently no way to specify which env vars to keep for the fingerprinting step. Describe the solution you'd like Add the parameter

extra_env_vars

to system_binary, just like it exists for adhoc_tool or shell_command. Describe alternatives you've considered Workaround the issue by creating a wrapper shell script that replies to only the fingerprinting using a special

args

value and forwards all other options and parameters to the target system binary. Additional context The fingerprinting error:

ValueError: Could not find a binary with name `drawio`.
The following paths were searched: /bin, /opt/drawio, /opt/homebrew/bin, /usr/bin, /usr/local/bin, /usr/sbin.

Btw, the error message is quite misleading as the binary can be found, just the fingerprinting fails. This was already reported in #19013. The generated

__run.sh

currently looks like this:

#!/usr/bin/env bash
# This command line should execute the same process as pants did internally.
cd /tmp/pants-sandbox-lpxUQZ
env -i  /opt/drawio/drawio --version

Executing

__run.sh

manually reveals the error:

$ env -i  /opt/drawio/drawio --version
