Amrit Sarkar commented on SOLR-11278:
-------------------------------------
Root cause of the assertion error ::
In bootstrap process, in bootstrap callable process,
{code}
Future<UpdateLog.RecoveryInfo> future = ulog.applyBufferedUpdates();
....................
}
return success;
} finally {
if (closed || !success) {
...................
boolean dropped = ulog.dropBufferedUpdates();
log.info("boostrap callable dropped :: " + dropped);
assert dropped;
}
}
{code}
{{ulog.dropBufferedUpdates()}} is getting calculated as {{false}} at ::
UpdateLog::dropBufferedUpdates::
{code}
/** Returns true if we were able to drop buffered updates and return to the
ACTIVE state */
public boolean dropBufferedUpdates() {
versionInfo.blockUpdates();
try {
log.info("dropBufferedUpdates :: state :: start " + state);
if (state != State.BUFFERING){
return false;
}
...............
{code}
This state is assigned *{{ACTIVE}}* instead of buffering and it returns
*{{false}}* and returns..
in UpdateLog, I cannot figure out where exactly {{state}} is getting assigned
as *ACTIVE* b/w {{applybufferedupdates}} and {{dropbufferedupdates}} and
running test to detect the same. Ideally the initial value of {{state}} is
assigned {{ACTIVE}}.
