Revert "cqfd: redirect command stderr to stdout" once again

[gportay]

This reverts commit 0cef50e once again.

The commit e8bc9af has mistakenly reverted the change ae5c830.

Thanks, change is merged. Could we have a test to catch stderr management misbehaviors?

I hesitated to make a test. I will do it.

[joufellasfl]

Thanks, this will help avoiding bringing this issue back to life every now and then :-)

Well, writing tests is not that simple; and cqfd does not work as expected.

cqfd run "cat /etc/os-release >&2" 2>/dev/null

This outputs the content of /etc/os-release, while I expected it do not.

This is because a pseudo tty is allocated since stdin is a tty (even if stderr is not).

From bash(1):

An interactive shell is one started without non-option arguments (unless -s is specified) and without the -c option, whose standard input and error are both connected to terminals (as determined by isatty(3)), or one started with the -i option. PS1 is set and $- includes i if bash is interactive, allowing a shell script or a startup file to test this state.

So I would need that change:

diff --git a/cqfd b/cqfd
index 9cff1ad..d888fe5 100755
--- a/cqfd
+++ b/cqfd
@@ -173,7 +173,7 @@ docker_run() {

        # interactive options if standard input is connected to a tty
        args+=(-i)
-       if tty -s; then
+       if [ -t 0 ] && [ -t 2 ]; then
                args+=(-t)
        fi

Note: I did it on dosh, my docker shell wrapper.

I added the tty -s to test -t change, it doesn't break any test, so either it's safe, or we don't have enough test coverage :). Let's see how it goes having it on master.

Oops, it stops to work... I need to fix it. sorry for the noise.

**|FAIL|cqfd without redirection should allocate a tty
**|FAIL|cqfd with stdin redirected to /dev/null should not allocate a pty
**|FAIL|cqfd with stderr redirected to /dev/null should not allocate a pty
  |PASS|cqfd with allocated pty should redirect stdout and stderr to same endpoint
**|FAIL|cqfd without allocated pty should redirect stdout and stderr to distinct entpoints

EDIT; I have move the test file to the end; so I guess a test modifies the .cqfdrc file without restoring it.

@joufellasfl, it is done; is it what you expected?

[gportay]

Hello, @joufellasfl any though on the tests?

Ping?
