bash @4.3.33_0: escapes non-latin symbols when completing paths with spaces

[xeron (Ivan Larionov)]

Steps to reproduce:

• Create a file or dir with at least one space in name and with some non-latin symbols (good example is "абвгдеёжзиклмнопрстуфчцчшщъыьэюя 1" because it includes whole Russian alphabet)
• Type "ls аб" and press <TAB>

Expected behavior: bash autocompletes a path and escapes only spaces

Actual behavior: bash autocompletes a path but escapes most of the symbols

I can't reproduce this using Linux and bash 4.2.37(1)-release and OS X bundled bash 3.2.57(1)-release.

This patch fixes this issue. Looks like the reason is readline.

[xeron (Ivan Larionov)]

Looks like bash was forced to use bundled readline in r87677. Also looks like debian's version of bash uses bundled readline as well. So I'm not sure my patch is correct.

But I has this issue with bundled one.

[xeron (Ivan Larionov)]

Ok this is interesting.

If I rebuild bash using Portfile from trunk it works OK.

So the issue is in bash which was installed by macports using prebuild package. It could be some environment differences or something.

I can reproduce this with the archive from the buildbot. If I build it locally it works as expected. I will try to force a rebuild on the buildbot.

Maybe readline behaves differently based on the locale settings during build? Although I tried local builds with LC_ALL=en_US.utf8 and LC_ALL=C, both work as expected.

[xeron (Ivan Larionov)]

Looks like rebuilding doesn't help. @4.3.39_0 installed from prebuilt package still has this issue.

[xeron (Ivan Larionov)]

Can't reproduce this with bash 4.4. Feel free to close.

[raimue (Rainer Müller)]

Thanks for the confirmation.
