Bug 531386 – >=app-shells/bash-completion-2.1 automatically loads new completions

• Status: RESOLVED WORKSFORME
• Product: Gentoo Linux

[Description Adrian 2014-12-02 00:19:55 UTC]

When no bash completions are enabled (via `eselect bashcomp`), the /usr/share/bash-completion/.pre file is never sourced. This means the autoloading magic is not enabled either.
However, enabling *any* bashcomp module via eselect causes the .pre file to be loaded, too, so the magic is there.

This is extremely confusing and not what one would expect.

Reproducible: Always

It's a feature.

[Comment 2 Adrian 2014-12-02 10:43:25 UTC]

It's not the autoloading itself this bug is about but the fact that I need to enable **some** completion to get this behaviour, which is a) not documented, b) not expected (why do I enable a random completion to get all of them).

This is weird. Which version of bash-completion are you using (with -r* part), exactly?

[Comment 4 Adrian 2014-12-02 11:03:55 UTC]

2.1-r2; it's a freshly installed system so there's no clutter from old versions etc.

I checked /etc/profile.d/bash-completion.sh and according the code there fits with what I noticed. the pre file is only loaded if there are other files to load

(You may want to reopen this so that it doesn't get lost.)

[Comment 6 Michał Górny 2014-12-06 19:49:55 UTC]

We don't really support autoloading prior to bash-completion-2.1-r90. In the earlier versions, you are required to enable all necessary completions via eselect.
