Subject: bug#63221: 30.0.50; [PATCH] Eshell should get user (and group) IDs in a connection-aware fashion
Date: Mon, 1 May 2023 22:42:53 -0700

[Message part 1 (text/plain, inline)]

This is sort of a continuation from bug#60722. Eshell gets the user's 
UID/GID in a few places, e.g. to decide when to prompt before deleting a 
file with "rm" (if you're root, it should prompt). However, these aren't 
connection-aware. That means that if you start Emacs as a normal user 
and then run "cd /sudo::", it doesn't recognize that you're now root, so 
it doesn't prompt.

Similarly, Eshell's "ls" implementation doesn't check for the 
connection-aware UID/username for ownership. And likewise for the "U" 
and "G" Eshell predicate operators.

Attached is a patch to fix this, which also adds a new utility function 
'file-group-gid'. Similar to 'file-user-uid' (added in bug#60722), it's 
just a connection-aware version of 'group-gid'.
