> Data race when getting index rebuild status
> -------------------------------------------
>
> Key: IGNITE-13119
> URL: https://issues.apache.org/jira/browse/IGNITE-13119
> Project: Ignite
> Issue Type: Improvement
> Reporter: Kirill Tkalenko
> Assignee: Kirill Tkalenko
> Priority: Major
> Fix For: 2.9
>
> Time Spent: 10m
> Remaining Estimate: 0h
>
> Now it is possible data race when getting status of building an index.
> This is possible due to method [1] can invoke earlier [2].
> It can reproduce if modify the code here:
> org.apache.ignite.internal.processors.query.h2.IgniteH2Indexing#rebuildIndexesFromHash
> But this will not give a 100% repeat of the problem.
> {code:java}
> rebuildCacheIdxFut.listen(fut -> {
> Throwable err = fut.error();
> if (isNull(err)) {
> try {
> U.sleep(10_000);
>
> markIndexRebuild(cacheName, false);
> }
> catch (Throwable t) {
> err = t;
> rebuildCacheIdxFut.onDone(t);
> }
> }
> if (nonNull(err))
> U.error(log, "Failed to rebuild indexes for cache: " + cacheName, err);
> });
> {code}
> [1] - org.apache.ignite.internal.IgniteInternalFuture#get()
> [2] - org.apache.ignite.internal.IgniteInternalFuture#listen
