bug#74739: 31.0.50; eshell/which doesn't return a non-zero exit code on not finding a file

eshell/which doesn't return a non-zero exit code on not finding a file. Yet it sends the output to stderr. It looks like there is an inconsistency.

Steps to reproduce:

~ $ which test-file
which: no test-file in ([...]/usr/local/bin:/usr/bin:/snap/bin)
~ $ which test-file | grep theoretical
which: no test-file in ([...]/usr/local/bin:/usr/bin:/snap/bin)
~ $ echo $?
0
~ $ which test-file 2>&1 | grep theoretical
~ [1] $

bug#74739: 31.0.50; eshell/which doesn't return a non-zero exit code on not finding a file

[Ship Mints]

I don't know why I'm choosing to answer eshell questions today...

which is an eshell built-in command. You can see this by running

  $ which which
  eshell/which is a native-compiled Lisp function in 'esh-cmd.el'.

Try running /usr/bin/false and then echo $? and you'll see the correct unix
command exit value.

I do not think eshell builtins are intended to behave the same way.

bug#74739: 31.0.50; eshell/which doesn't return a non-zero exit code on not finding a file

[the_wurfkreuz via Bug reports for GNU Emacs, the Swiss army knife of text editors]

[-- Attachment #1: Type: text/plain, Size: 25591 bytes --]

I understand that eshell built-ins might behave differently from Unix commands, but isn't it still inconsistent for eshell/which to use stderr (indicating an error) while returning exit code 0 (indicating success)? If this isn't an accidental oversight, i'd be interested to know why it was designed this way.

But yeah, i'm not an expert on unix, maybe other standard utilities also behave like this.

> I understand that eshell built-ins might behave differently from Unix commands, but isn't it still inconsistent for eshell/which to use stderr (indicating an error) while returning exit code 0 (indicating success)? If this isn't an accidental oversight, i'd be interested to know why it was designed this way.

bug#74739: 31.0.50; eshell/which doesn't return a non-zero exit code on not finding a file

[Ship Mints]

[-- Attachment #1: Type: text/plain, Size: 27301 bytes --]

Not a big eshell user myself and I can't speak to its history. Reading the
code suggests that return values from functions like eshell/which weren't
considered significant by the authors. Every "print" ultimately seems to
return nil. Not sure if there's a way to detect if errors make it to the
stderr channel eshell is coded to use. I suppose you could write your own
eshell aliases in elisp to return better values. Seems like a lot of work,
though.
