Trolli Schmittlauch 9bf7365a2c include target ID in request to address individual vserver 
- necessary for dispatching the request to a certain vserver

- contributes to #2
 2020-09-19 20:41:58 +02:00
Trolli Schmittlauch 5e745cd035 only specify upper key bound when querying load 
As a querying node does not always know the lower bound of the queried
segment – determined by the predecessor – let the currently responsible
node provide that bound instead.

Trolli Schmittlauch 1fc264a226 manage logging via file handle 
reason: `appendFile` combined with lazy evaluation lead to exhaustion of
open file descriptors, as each file is opened again for each write and
due to lazy evaluation is kept open multiple times.

Trolli Schmittlauch ab9d593a1b bugfix: fix wrong partial Response sender access 
- replaces improper record field access of `sender`, only existing in a
  Request, by `senderID` of a Response
- fixes the resulting exception-crash
- adds new function that enqueues a verification mark and timestamp bump
  of an existing cache entry

Trolli Schmittlauch b23201a49c Make key lookups fail after request exhaustion instead of providing default 
Returning the own node as a default does not make sense in all contexts:
Especially for bootstrap joining this can be harmful, so signalling
instead that the lookup failed makes distinguishing on a case by case
basis possible.

Also contributes to #57
