Description:
I create a partitioned indexed MyISAM table.
I insert a row.
I insert another row, using INSERT ... SELECT.
I insert another row, using INSERT ... SELECT.
I see an error:
ERROR 1030 (HY000): Got error 124 from storage engine

This happens only if I use one of these partitioning clauses:
PARTITION BY HASH (column_name) PARTITIONS n;/* where n > 1 */
PARTITION BY KEY (column_name) PARTITIONS n; /* where n > 1 */
PARTITION BY LIST (column_name) (PARTITION ..., PARTITION ...);

This happens with mysql-5.1 and mysql-5.1-bugteam, pulled today,
so I doubt there is a connection with Bug#35931.

How to repeat:
mysql> create table t (s1 int) partition by hash(s1) partitions 2;
Query OK, 0 rows affected (0.08 sec)

mysql> create index i on t (s1);
Query OK, 0 rows affected (0.07 sec)
Records: 0  Duplicates: 0  Warnings: 0

mysql> insert into t values (1);
Query OK, 1 row affected (0.00 sec)

mysql> insert into t select s1 from t;
Query OK, 1 row affected (0.00 sec)
Records: 1  Duplicates: 0  Warnings: 0

mysql> insert into t select s1 from t;
ERROR 1030 (HY000): Got error 124 from storage engine

Works for me in 5.1.25:

C:\Program Files\MySQL\MySQL Server 5.0\bin>mysql -uroot -proot -P3310 test
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 1
Server version: 5.1.25-rc-community MySQL Community Server (GPL)

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

mysql> create table t (s1 int) partition by hash(s1) partitions 2;
Query OK, 0 rows affected (0.25 sec)

mysql> create index i on t (s1);

Records: 0  Duplicates: 0  Warnings: 0

mysql> insert into t values (1);

mysql> insert into t select s1 from t;

mysql> insert into t select s1 from t;
Query OK, 4 rows affected (0.05 sec)

mysql> insert into t select s1 from t;
Query OK, 8 rows affected (0.05 sec)
Records: 8  Duplicates: 0  Warnings: 0

So, looks like some recent regression.

This is recent regression.

I tried on tree that I pulled yesterday evening:

mysql> create table t (s1 int) partition by hash(s1) partitions 2;
Query OK, 0 rows affected (0.08 sec)

mysql> create index i on t (s1);
Query OK, 0 rows affected (0.07 sec)
Records: 0  Duplicates: 0  Warnings: 0

mysql> insert into t values (1);
Query OK, 1 row affected (0.05 sec)

mysql> insert into t select s1 from t;
Query OK, 1 row affected (0.00 sec)
Records: 1  Duplicates: 0  Warnings: 0

mysql> insert into t select s1 from t;
ERROR 1030 (HY000): Got error 124 from storage engine

mysql> select version();

      Bug#38005 Partitions: error with insert select.
      
      
      MyISAM blocks index usage for bulk insert into zero-records tables.
      See ha_myisam::start_bulk_insert() lines from
      ...
          if (file->state->records == 0 ...
      ...
      
      That causes problems for partition engine when some partitions have records some not
      as the engine uses same access method for all partitions.
      
      Fixed by returning EOF from ha_myisam::index_first for empty tables.

Noted in 5.1.29 changelog.

Using INSERT ... SELECT to insert records into a partitioned MyISAM
table could fail if some partitions are empty and others are not.

Leaving report status unchanged; this is early documentation of an upcoming push into 5.1.29.
