Hi guix,

 Using latest guix, and considering a local manifest.scm file 
 with only

   (specifications->manifest (list "python"))

 Following command works

   guix shell --container -m manifest.scm -- python3

 But

   guix shell --container -- python3

gives an error. However,

   guix shell --container

followed by

   python3

works.

 So, by just removing the ’-m manifest.scm’ flag, I get an error.

Regards,

Cayetano Santos

It works correctly for me.  With Guix f43a783:

$ guix shell -C -m manifest.scm

Problem is

 guix shell -C -- python3

Tried after ’guix pull’ and problem remains.

Which revision do you use?  Because using f43a783, it fails as expected. :-)

Are you running Guix on foreign distro or Guix System?

I’m using guix 05deb26.

Is it expected to fail when I remove the ’-m manifest’ flag and I 
just run ’guix shell -C -- python3’ ?

> Are you running Guix on foreign distro or Guix System?

Foreign, on top of ArchLinux.

The command "guix shell -C -- python3" fails.  It cannot work, because
the environment (new shell) is empty.  You need to provide what this
shell has to contain, via command line package list or via manifest.

To my understanding, in this blog entry

 https://guix.gnu.org/en/blog/2021/from-guix-environment-to-guix-shell/

they claim that "guix shell automatically loads guix.scm or 
manifest.scm, from the current directory"

No need to "-m manifest.scm", then.

Ah yes, sorry.  Since I personally find implicit a bad thing, I have
forgotten about it. :-)
Anyway!

Indeed, there is a bug.  It comes from 'stat:uid' vs 'getuid' in
'find-file-in-parent-directories'.  On my machine, this

    (= (stat:uid stat) (getuid))

compares 0 against 1001.

Hi,

I am experiencing a similar situation without the container.  At work,
I need some special Emacs packages, that I don't need/want in my normal
setup, so I do `guix shell -m manifest.scm -- emacs'.  Even with the
directory added to the good noodles list, `guix shell -- emacs' fails,
probably because Guix assumes it has arguments when those really are
just the command to run.  IOW the check for "when is implicit okay"
might be too narrow for this use case.

Cheers

Similar root, I guess, described by https://issues.guix.gnu.org/52347#8 :-)

I am pretty sure all files are owned by the same user in my case.  Can
stat:uid really return 0 then?

Maybe I am doing wrong but I just 'pk' in find-file-in-parent-directories. :-)

You are doing wrong:

  (if (or (not interactive?) ; true if giving -- COMMAND
          disallow-implicit-load?
          (options-contain-payload? opts))

So the pk in find-file-in-parent-directories should not even fire.  I'm
pretty sure the interactive constraint has a reasoning that was
explained back then, so we should investigate carefully whether we want
to overthrow that.  Warning, that noninteractive use of `guix shell'
requires an explicit manifest is also an option imo.

By the way, if we do search for a file, but find none, the warning
(warning (G_ "no packages specified; creating an empty environment~%"))
is displayed twice; once by auto-detect-manifest and once by guix-
environment*.  We should probably change that string to something that
indicates that we've attempted to auto-load a manifest.

Cheers

Yes, indeed.  I simply grepped "manifest" and looked at
'find-file-in-parent-directories', because if it is not called, the
"manifest" file cannot be loaded. :-)  Then I incorrectly used the
wrong command line invokation.  Bad day with a lot of inattentive
today. :-/

I am in favour to keep it explicit. (Personally, I already find that
"guix shell" is wrong ;-))

Seems like suggest-command-name is passing #f to string-closest instead
of a list (a bug!).

Hi Cayetano,

As Liliana noted, this is the intended behavior: auto-loading of
‘manifest.scm’ happens only for interactive use.  This is to keep
non-interactive use context-independent and thereby avoid bad surprises.

Note that when ‘manifest.scm’ is auto-loaded, a message is printed; when
it’s not considered, no message is printed.  Likewise, when creating an
empty environment, a warning is printed (twice even :-)).

Any suggestions on things we might improve to avoid confusion?

Thanks,
Ludo’.
