Trolli Schmittlauch a803751213 fix infinite loops during lookups 2020-05-17 21:31:43 +02:00
Trolli Schmittlauch 18bdcce266 re-implement NodeCache data structure to emulate ring properly 
- previously, there was at least 1 gap in the identifier ring
- now use normal integer comparison again, but forward lookups using
  proxy entries at the ID space boundaries
- wrap cache operations to properly handle proxy elements
- fix all previously working tests
- document choice of cache data structure
