[issue10496] "import site failed" when Python can't find home directory (sysconfig._getuserbase)

STINNER Victor added the comment: Main changes of the patch, if the current user has no home directory (no entry in /etc/passwd) and there is HOME environment variable: - sysconfig.get_config_vars() doesn't have a 'userbase' variable. sysconfig.get_config_var('userbase') returns None as any

Éric Araujo added the comment: In the absence of tests or doc update, can you tell in English what the new behavior is? IIUC, when the home dir is not found, all the variables that depend on it would not exist, right? Or would they be set to None? -- ___

Tarek Ziadé added the comment: As discussed w/ Victor, a process should be able to run Python even if its user does not have a home. So the call to _getuserbase() should be protected. But then we have to control that all the code that uses CONFIG_VARS['userbase'] is protected when the valu
