[Firebird-devel] Collection of garbage in record with uncommitted version

[Dimitry S. <sd...@ib...>]

   Hello, All.

   If a record has uncommitted head version created by active transaction and some garbage 
in backversions "tail", can anyone (background GC thread, sweep or parallel transaction) 
wipe this garbage from the tail while the transaction is still active?
   I can't understand why list_staying() is so picky: it scans for every next version from 
the beginning which raise its complexity to O(N^2).
