Bug 2359689

Reaffecting to python-argcomplete as the problem is related to /etc/bash_completion.d/_python-argcomplete

With old python3-argcomplete it was working as expected (f39)

Removing python3-argcomplete solves the issue (tested on F40 and F41)
Version 3.6.2 in testing is also affected

The problem is in 

           elif __python_argcomplete_run "${interpreter[@]}" -m argcomplete._check_console_script "$SCRIPT_NAME"; then
                ARGCOMPLETE=1

As "/usr/bin/php -m"  is a valid command (modules list)

So the problem (if I understand it correctly) is the combination of:

 1. /etc/bash_completion.d/_python-argcomplete runs for everything
 2. the script runs $interpeter -m argcomplete._check_console_script "$SCRIPT_NAME" (assuming $interpreter is some kind of Python)
 3. php -m argcomplete._check_console_script "$SCRIPT_NAME" exists successfully
 4. argcomplete takes over the completion for some php scripts

correct?

> correct?

Yes.

Still digging.

/etc/bash_completion.d/_python-argcomplete contains

    complete -o default -o bashdefault -D -F _python_argcomplete_global

/usr/share/bash-completion/completions/pie contains

    complete -F _sf_pie pie

According to "complete" man page

    The -D option indicates  that  other  supplied options  and actions should apply to the ``default'' command completion;
    that is, completion attempted on a command for which no completion has previously been defined.

So _python-argcomplete should not be used for pie, which has a completion defined

So maybe a bash-completion issue or a load order issue.

So a possible fix

Moving _python-argcomplete from user directory (/etc) to system directory (/usr/) solves the load order issue

   mv /etc/bash_completion.d/_python-argcomplete /usr/share/bash-completion/completions/_python-argcomplete

- pie completion works
- virt-install (which use _python-argcomplete) works

Moving to /usr breaks argcomplete entirely (which is perhaps why it solves this). See bz2211862.

Fedora RPM-packaged scripts using argcompelte all have Python shebangs.

Hence, I wonder if getting rid of the entire book...

            elif __python_argcomplete_run "${interpreter[@]}" -m argcomplete._check_console_script "$SCRIPT_NAME"; then
                ARGCOMPLETE=1
            fi

...(which is located in an elif branch for scripts without a Python shebang) would not be good enough for us, until an upstream solution is found.

As RHEL-10 is also affected, reported as https://issues.redhat.com/browse/RHEL-87652

Remi, please test the CI build of https://src.fedoraproject.org/rpms/python-argcomplete/pull-request/40 -- I'll check if it breaks Python scripts using argcomplete.

Can you please also push the fix to stable branches (f40+) ?
