Hey everyone. Can someone help me understand why makepkg sets `LANG=C` for invoking bsdtar? According to dreisner, the change was introduced in 537a335cc724a5c7c, but the commit message there only explains what the change does, not how it does it:
> Use C locale for bsdtar calls during package creation > This ensures packages build on a UTF-8 locale system with non-ASCII character > names can be installed on non-UTF-8 systems. I'm asking because I'm getting errors regarding group names (but I assume it'd be the same with user names) like this one: > bsdtar: somefile: Can't translate gname 'Отсутствует' to UTF-8 Removing `LANG=C` makes the errors go away. The error can be reproduced outside of makepkg just by running `LANG=C bsdtar -cf /tmp/foo.tar *` in a suitable directory. I know this is not exactly a common scenario on Arch Linux, as the combination of fakeroot, the special status of the root user and group and the ASCII-only policy of groupadd makes it very unlikely that the packaging bsdtar invocation will encounter any such problems. In Cygwin however, the probability of encountering non-ASCII user/group names is pretty high. I wonder if there's some combination of locale settings and bsdtar arguments that allows for the thing the commit was targeted on, but also for non-ASCII user/group names. One possibility would be to specify `--uname "" --gname ""` to bsdtar, assuming the names are useless for pacman anyway. If manipulating the locale variables is more desirable, I ask for an example of the situation that this change fixed (or a link), otherwise I don't know how to correctly test it. Extending this idea further, makepkg could pass `--uname root --gname root --uid 0 --gid 0` to bsdtar, which could help with moving the bsdtar/gnupg step out of fakeroot, if it's not possible already (and if it's desirable). That's of course assuming that all packages contain files with only root.root ownership. -- David Macek
