Hello
After upgrading to 3.23.31, FULLTEXT selects give often "error -1 from
table handler" for me. The error log says "ft_read_first: Got error
-1 when reading table foo". I think I have not seen those for older
3.23.x versions (x=28 or so), at least not that frequently.
A small example to reproduce the error:
DROP TABLE IF EXISTS t1;
CREATE TABLE t1 (
id mediumint unsigned NOT NULL auto_increment,
tag char(6) NOT NULL default '',
value text NOT NULL default '',
PRIMARY KEY (id),
KEY kt(tag),
KEY kv(value(15)),
FULLTEXT KEY kvf(value)
) TYPE=MyISAM;
DROP TABLE IF EXISTS t2;
CREATE TABLE t2 (
id_t2 mediumint unsigned NOT NULL default '0',
id_t1 mediumint unsigned NOT NULL default '0',
field_number tinyint unsigned NOT NULL default '0',
PRIMARY KEY (id_t2,id_t1,field_number),
KEY id_t1(id_t1)
) TYPE=MyISAM;
INSERT INTO t1 (tag,value) VALUES ('foo123','bar1');
INSERT INTO t2 VALUES (2231626,64280,0);
INSERT INTO t1 (tag,value) VALUES ('foo123','bar2');
INSERT INTO t2 VALUES (2231626,64281,0);
SELECT DISTINCT t2.id_t2
FROM t2, t1
WHERE MATCH (t1.value) AGAINST ('baz')
AND t1.id = t2.id_t1;
The error occurs during final SELECT. I've seen it only for FULLTEXT
searches; if I use e.g. "WHERE t1.value LIKE 'baz%' in that statement,
everything works fine.
P.S. Self-compiled 3.23.31 on sparc64 Linux (Debian stable).
cheers
