Running from a web server ,on Mac OS Racket try to open pref-dir of admin user that installed Racket instead of the one of current-user

Hi,

it is not easy to reproduce as it requires, Mac OS, a web server running an application that run racket.

i run the web server that seems to run under user _www:

ps xau
_www 13856 0,0 0,6 410998272 204400 s007 S+ 11:52 0:00.63 /Applications/Racket/bin/racket

but when the web application using racket try to use the preference file it fall back to the one of me, mattei, administrator of the host, as seen in the output of httpd log:

[3] => interpole-fields : Racket/Scheme+ (find-system-path 'pref-file): /Users/mattei/Library/Preferences/org.racket-lang.prefs.rktd

Racket must use the preference file from _www which is the proprietary of the Rackett running process.

How did you start the Racket program?

I asked ChatGPT to explain the output from ps xau and it said:

TT: s007 — controlling terminal (an interactive shell session)

This seems odd if the Racket process is invoked by the web server.

FWIW find-system-path eventually calls rktio_system_path which is defined here:

https://github.com/racket/racket/blob/master/racket/src/rktio/rktio_fs.c#L2302

I think the current user is taken from the shell rather than from the user that owns the process.

ps is just the command ps of unix
print statistics of processes

about current user taken from shell and it seems the envionment is good:

(myvenv3.10) _www@mac ~ % printenv
LANG=fr_FR.UTF-8
USER=_www
LOGNAME=_www
HOME=/Library/WebServer
PATH=/Users/mattei/myvenv3.10/bin:/usr/local/bin:/System/Cryptexes/App/usr/bin:/usr/bin:/bin:/usr/sbin:/sbin:/var/run/com.apple.security.cryptexd/codex.system/bootstrap/usr/local/bin:/var/run/com.apple.security.cryptexd/codex.system/bootstrap/usr/bin:/var/run/com.apple.security.cryptexd/codex.system/bootstrap/usr/appleinternal/bin:/opt/pmk/env/global/bin:/Library/Apple/usr/bin:/opt/homebrew/bin
SHELL=/bin/zsh

mount_authenticator_shm=/pamF48D8F78B233
SSH_CLIENT=::1 50824 22

PS1=(myvenv3.10) %n@%m %1~ %#
VIRTUAL_ENV_PROMPT=(myvenv3.10)
_=/usr/bin/printenv

user is well _www but this output show mattei in PATH and other place that should not be, this could be causing because for using _www account i'm first logged in mattei and do ssh _www@localhost

i will check all the varriable from web server app , not from console as it is what is important.
