BUG: nextuid creates GUI users (uid >= 500) rather than "hidden" users (<500)

[matt@…]

When a port such as dbus creates a user using the adduser function, the user will be visible in the Accounts Preference pane etc. This is because Mac OS X treats uids >= 500 as login users, and pextlib's nextuid function just takes maxuid+1 for the userid.

A better approach in NextuidCmd() in Pextlib.c would be to do something like

int uid = 100; while (getpwuid(uid)) {

uid++;

} tcl_result = Tcl_NewIntObj(uid);

or similar (I haven't tested this code).

Good suggestion, but I cannot tell on my own what implications it might have. Setting it to "Needs developer review" for now. Thanks for the report!

I just fixed this in r23720 without being aware of the existence of the ticket :)

Anyway, nextuid and nextgid both pick up the first uid/gid >= 100, using basically the same code you pasted.

This was reverted by Landon because users with uid's < 500 are reserved for system usage. I'll keep the ticket closed since the original suggestion is not entirely applicable, but I'll leave the ticket in this milestone and wont mark it as "invalid" in case someone wants to work on it to find a better solution (hidden users with uids > 500? I think Landon said there is a way to accomplish that, though he didn't remember it at the moment).
