The ancient decision to let undo perform the checkout by itself still
makes sense from a UX perspective, but keeps requiring specific handling
of edge cases.
In this case, the easiest way to deal with trailing input is to just
abort entirely.
Also: updated lib/RevBank/Plugins.pm to import 'isa' and get up to 5.32
level.
Activating statiegeld_tokens will limit the use of the statiegeld plugin
for container deposit refunds to what was bought at this venue.
Still needs documentation.
Changes to 'statiegeld' and 'undo' were made to support the new
plugin, specifically:
- metadata (attributes) added in $cart->add, for the statiegeld_tokens
plugin to use.
- statiegeld plugin now shares a global variable (configuration).
- undo can now be rolled back during hook_checkout.
The signatures feature has been "experimental" since Perl 5.20 (May 2014), but
expected to stay. After 8 years I'm ready to take the risk :)
Have added Perl v5.28 (June 2018) as the minimum requirement, even though the
current revbank should work with 5.20, to see if this bothers any users. Perl
v5.28 is in Debian "buster", which is now oldstable.
