archive handler stuck with locale issues

[jspi...@gmail.com]

Trying to update with the following config snippet:

files: (
{
filename = "rootfs.tar.gz";
type = "archive";
path = "/mnt/rootfs";
preserve-attributes = true;
}
);

Get this error:

[ERROR] : SWUPDATE failed [0] ERROR handlers/archive_handler.c : extract : 110 : archive_read_next_header(): Linkname can't be converted from UTF-8 to current locale. 1

swupdate then freezes and does not exit or continue unpacking the archive.

Try passing --posix to tar when you are creating rootfs.tar.gz. This seems to be due to a libarchive bug https://github.com/libarchive/libarchive/issues/587.

Seems this bug is worse than I originally thought, the commit message
in https://github.com/mpv-player/mpv/commit/1e70e82baa9193f6f027338b0fab0f5078971fbe
gives a bit of an overview of the problem, I have no idea how to fix
this in swupdate though as libarchive seems to do insane things with
locale settings which are often non-standard for embedded systems(I've
yet to find a working locale configuration with buildroot).

I came up with a potential fix here https://github.com/sbabic/swupdate/compare/master...jameshilliard:locale which should work as long as one of the env variables LC_ALL, LC_CTYPE, LANG or the system locale is set to a valid UTF-8 locale, I did also send the patch to the mailing list(although it may have been caught in a spam filter since it didn't seem to show up yet).

There's been more action on this recently.  See the end of https://github.com/libarchive/libarchive/issues/587

Several people have patched Swupdate's env for their systems.

It was a bug for me on Gatesgarth using swupdate and meta-swupdate.
