package names that contain `x86_64` break xbps-install/xbps-remove

[classabbyamp]

xbps will successfully index a package with the name containing x86_64 but cannot install it (or sometimes can, but cannot uninstall it). I was unable to reproduce this with another architecture (like calling a package foo-aarch64-1.0_1) or with just a false revision (like foo_1-1.0_1).

mkdir -p pkg/foo/bar repo root
echo asdf > pkg/foo/bar/baz
cd repo
xbps-create -A noarch -n foo-x86_64-1.0_1 -s "foo pkg" ../pkg
xbps-rindex -d -a ./*.xbps
cd ..
xbps-install -r root -R repo -yvd foo-x86_64

foo-x86_64 looks like pkgname foo, version x86, revision 64. Passing exact pkgver as argument to xbps-install is a documented feature to select package from repository by available version.

Would you suggest to reject pkgnames that look like pkgver in xbps-create?

Would you suggest to reject pkgnames that look like pkgver in xbps-create?

this is probably the most sane solution

it seems that you're right about it interpreting foo-bar-x86_64 as foo-bar, version x86, revision 64, as i think it gets confused looking for the foo-bar when trying to configure packages.

furthermore, in this reproducer, you get stuck with the package:

$ xbps-query -r root -l
uu foo-1.0_1            foo pkg
uu foo-bar-x86_64-1.0_1 foo pkg
$ xbps-remove -r root -Ry foo

for some context: I ran into this when splitting qemu's emulators into packages like qemu-system-x86_64. Had to manually edit the pkgdb to remove qemu-system-x86_64.
