Description
Description of the bug:
Bazel tries to get user name to figure out output_user_root even if --output_user_root is passed in. However, GetUserName is a fallible call in an environment where $USER is unset, and getuid or getpwuid don't work properly. Such situation is possible in isolated environments like processed launched by nsjail.
The only option seems to be setting $USER, which is actually unused if --output_user_root is specified. I'd expect setting --output_user_root to be good enough for getting around this.
What's the simplest, easiest way to reproduce this bug? Please provide a minimal example if possible.
# install nsjail, then
./nsjail -Mo --chroot / --user 99999 --group 99999 -- /bin/sh -i
...
sh-5.1$ bazel
FATAL: $USER is not set, and unable to look up name of current user: (error: 0): Success
