Changeset: 338ff6b35b34 for MonetDB
URL: https://dev.monetdb.org/hg/MonetDB?cmd=changeset;node=338ff6b35b34
Modified Files:
sql/storage/bat/bat_storage.c
Branch: Apr2019
Log Message:
This assertion no longer always holds:
It can happen for concurrent write-only transactions,
say a truncate and an insert transaction,
that the truncate happens between the start and end of the insert
which is a valid sequence of events but one that violates
the deleted assertion.
