Subject: [bug#30256] [PATCH 3/3] scripts: environment: Add --no-cwd.
Date: Fri, 02 Mar 2018 11:54:30 +0100	[thread overview]
Message-ID: <87tvtyhhnd.fsf@gnu.org> (raw)
In-Reply-To: <7bc71eaa3cff48ec7dc0d4fe406dde9482b716a9.1516937216.git.mtg@gnu.org> (Mike Gerwitz's message of "Thu, 25 Jan 2018 22:29:45 -0500")

Mike Gerwitz <mtg@gnu.org> skribis:

> * doc/guix.texi (Invoking guix environment): Add --no-cwd.
> * guix/scripts/environment.scm (show-help, %options): Add --no-cwd.
> (launch-environment/container): Add 'map-cwd?' param; only add mapping for cwd
> if #t.  Only change to cwd within container if #t, otherwise home.
> (guix-environment): Error if --no-cwd without --container.  Provide '(not
> no-cwd?)' to launch-environment/container as 'map-cwd?'.
> * tests/guix-environment.sh: Add test for no-cwd.

This one LGTM as well (with the test moved to
guix-environment-container.sh).  There’s just a minor issue:

This test would fail for me because my test store is at
~ludo/src/guix/test-tmp/store and my CWD is ~/src/guix.  So when using
both --user and --no-cwd, the effect is that
~ludo/src/guix/test-tmp/store is not available at all within the
container, and thus execve("/bin/sh") fails with ENOENT:

--8<---------------cut here---------------start------------->8---
$ ./test-env guix environment --bootstrap --container --no-cwd --user=foo --ad-hoc guile-bootstrap

$ echo $?
1
--8<---------------cut here---------------end--------------->8---

Thoughts?

TIA,
Ludo’.
