Changeset: 229207671873 for MonetDB URL: https://dev.monetdb.org/hg/MonetDB/rev/229207671873 Added Files: sql/test/Tests/blob_query.test Modified Files: sql/test/Tests/All Branch: default Log Message:
Add test for query that seems to crash on manycore systems On the binresultset branch, the tests bincopy_blobs_on_client and bincopy_blobs_on_server crash on systems with many threads. This test contains the same query, but without the COPY BINARY. diffs (100 lines): diff --git a/sql/test/Tests/All b/sql/test/Tests/All --- a/sql/test/Tests/All +++ b/sql/test/Tests/All @@ -145,3 +145,4 @@ as3ap orderby-nulls-first-last +blob_query diff --git a/sql/test/Tests/blob_query.test b/sql/test/Tests/blob_query.test new file mode 100644 --- /dev/null +++ b/sql/test/Tests/blob_query.test @@ -0,0 +1,87 @@ +statement ok +START TRANSACTION + +# We need blobs of sizes 0..999 +statement ok +CREATE TABLE blobs +AS SELECT + t1.value AS nr, + CAST( + sys.group_concat( + CASE WHEN t2.value IS NOT NULL THEN 'DB' ELSE '' END + , '') + AS BLOB) AS blb +FROM + sys.generate_series(0, 1000) AS t1 +LEFT JOIN + sys.generate_series(0, 1000) AS t2 +ON t2.value < t1.value +GROUP BY nr +ORDER BY nr + +# to match sql/test/bincopy/bincopy_blobs_on_server, +# row N must have a blob of length N mod 1000, +# unless N is 2 mod 3. +statement ok +CREATE TABLE foo(id INT NOT NULL, b BLOB); +INSERT INTO foo +SELECT + nums.value AS id, + blobs.blb AS b +FROM + sys.generate_series(0, 1000000) AS nums +LEFT OUTER JOIN + blobs +ON nums.value % 1000 = blobs.nr AND nums.value % 3 <> 2 +ORDER BY id + +# In sql/test/bincopy/bincopy_blobs_on_server, the query with the UNION +# seems to try to allocate unreasonable large intermediate BATs +# when run on a system with many threads. +# For example, heaps of 17 or 28 GiB. + +# First try the parts separately + +query TIT +SELECT 'nulls', COUNT(*), NULL FROM foo WHERE (b IS NULL) <> (id % 3 = 2) +---- +nulls +0 +NULL + +query TIT +SELECT 'lengths', COUNT(*), NULL FROM foo WHERE b IS NOT NULL AND id % 1000 <> length(b) +---- +lengths +0 +NULL + +query TIT +SELECT 'blob6', NULL, b FROM foo WHERE id = 6 +---- +blob6 +NULL +DBDBDBDBDBDB + +# This is the one that seems to crash + +query TIT +SELECT 'nulls', COUNT(*), NULL FROM foo WHERE (b IS NULL) <> (id % 3 = 2) +UNION +SELECT 'lengths', COUNT(*), NULL FROM foo WHERE b IS NOT NULL AND id % 1000 <> length(b) +UNION +SELECT 'blob6', NULL, b FROM foo WHERE id = 6 +---- +nulls +0 +NULL +lengths +0 +NULL +blob6 +NULL +DBDBDBDBDBDB + + +statement ok +ROLLBACK _______________________________________________ checkin-list mailing list -- checkin-list@monetdb.org To unsubscribe send an email to checkin-list-le...@monetdb.org
