reproducible builds problem

[bmwiedemann]

While working on reproducible builds for openSUSE (sponsored by the NLnet NGI0 fund), I found that
our tiny package varies in every build.

Another developer pointed at HashMaps in

tiny/crates/term_input_macros/src/tree.rs

Line 6 in ee8615a

use std::collections::HashMap;

with non-deterministic iteration order.

Maybe it could be replaced with indexmap, ordermap or something else...

Thanks for reporting this. You were right that the hash map in the macro was the cause. I've updated it to IndexMap and made 10 builds and they were all identical, so the issue should be fixed. Please re-open if it isn't.
