Couldn't reproduce on mariadb-5.5.30-tokudb-7.1.0.
Test case (to be run with TokuDB enabled):
SET NAMES latin1; CREATE TABLE t1 (a INT) ENGINE=TokuDB; INSERT INTO t1 VALUES (1),(2); CREATE TABLE t2 (b INT) ENGINE=TokuDB; INSERT INTO t2 VALUES (3),(4); CREATE TABLE t3 (c VARCHAR(3), INDEX(c)) ENGINE=TokuDB; INSERT INTO t3 VALUES ('foo'),('bar'); EXPLAIN SELECT * FROM t1 WHERE a IN ( SELECT b FROM t2 ) OR ( 'qux' ) IN ( SELECT c FROM t3 );

Both of these examples crash because TokuDB can not handle index_end getting called after the transaction is committed. Here is a trace in which external_lock creates the txn, index_init creates a db cursor with the txn (not shown), index_read uses the cursor, the txn is committed, and then index_end is called (too late so tokudb hits the assert).

131206 7:29:24 [ERROR] TokuDB: toku_c_close: Transaction cannot do work when child exists
/home/prohaska/ma5534/mariadb/storage/tokudb/ha_tokudb.cc:4543 index_end: Assertion `Handlerton: r==0 ' failed (errno=0)
if the storage engine is expected to handle index_end after the transaction commits, then tokudb will have to maintain a list of handler's that need to be cleaned up when a transaction commit occurs. is this the case?
No, wait. At the moment I am thinking that it is not the case and that commit should never happen in the middle of the index scan.
I'll know more soon.
it looks like join cleanup happens too late.
we are testing this change: https://github.com/Tokutek/ft-engine/commit/d9edc3fb2db4436636627bbeabae7a3cbed3bae3
Sergei, could you please review the attached bug fix? Thanks.
Ok to push.
Also a somewhat different test case which causes the same assertion failure:
CREATE TABLE t1 (a VARCHAR(8), INDEX(a)) ENGINE=TokuDB;
INSERT INTO t1 VALUES ('foo'),('bar');
CREATE TABLE t2 AS SELECT ( 'qux' ) IN ( SELECT a FROM t1 ) AS f1;
