There was a problem hiding this comment.
These two tests that have been removed asserted that n.pterm = n.term could still be executed, resulting in a situation where we should recover from the possibility of having an incorrect pterm.
Since its removal in #6060, these tests should be removed. We should never have this situation occur anymore.

If we are leader and store two entries, the first having quorum and being committed/applied and the second not having quorum. A new leader should be able to truncate the second entry.
That was not possible before as the
n.loadEntry(ae.pindex)andn.truncateWAL(eae.pterm, eae.pindex)combination would remove two entries, not just one. If theae.pindex < n.pindex, the entry that has a matchingae.pindexis stored at stream sequenceae.pindex+1.Signed-off-by: Maurice van Veen [email protected]
