Hoss Man commented on SOLR-10251:
---------------------------------
A few misc observations...
* this line is comparing the commits on master _now_ to the commits on master
just prior to a core reload
** so failure has nothing to do with replicaiton
** Looks like a merge is happening before/after reload -- but before test gets
list of commits?
*** Possible from RandomMergePolicy?
* At this line where this test fails, a non-nightly run won't have indexed a
single doc -- so this particular failure will only be observable with
{{-Dtests.nightly=true}} ...{code} int docs = TEST_NIGHTLY ? 200000 : 0;
{code}
* i don't understand the point of this test at all ... it doesn't compare
anything between master/slave except after a commit -- so where does the
"AfterCoreReload" part come into play?
** it's particularly wonky given that half of the asserts comparing
master/slave are about haven an identical {{numFound=0}} for a {{\*:\*}} search
against an empty index! (unless nightly)
> reliable TestReplicationHandler.doTestReplicateAfterCoreReload failure --
> more (identical) commits then expected
