Build Identifier:
monetdb (mclient) hangs if an insert using a select statement is executed. This only happens when there is a foreign key constraint.
Use case example:
CREATE TABLE table1 (
tablename VARCHAR(50) NOT NULL,
PRIMARY KEY (tablename)
);
CREATE TABLE table2 (
table1_name VARCHAR(50) NOT NULL,
FOREIGN KEY (table1_name) REFERENCES table1 (tablename)
);
insert into table1 (tablename) values ('A');
insert into table2 (table1_name) values ('A');
-- Things go wrong here:
insert into table2 (table1_name) select 'A';
The process hangs indefinitely, and if the database is not stopped (ie, the mclient may be escaped by ctrl-C, but the server still continues to run), the process will eat up all CPU time and, in my case, overheat and shut down my macbook :-(.
There are no useful entries in the log file related to this.
On Linux (Ubuntu 11.04, 64 bit, through a VM on OS X), this bug shows up as well, but then the mclient quits with a '!Connection terminated' in the logfile. I have not checked if the background server process hangs indefinitely.
The bug does not show up in an older version (specifically, the Oct2010 release).
Reproducible: Always
Steps to Reproduce:
Create a database
Use the client to access the database (via SQL)
Execute the following SQL:
CREATE TABLE table1 (
tablename VARCHAR(50) NOT NULL,
PRIMARY KEY (tablename)
);
CREATE TABLE table2 (
table1_name VARCHAR(50) NOT NULL,
FOREIGN KEY (table1_name) REFERENCES table1 (tablename)
);
insert into table1 (tablename) values ('A');
insert into table2 (table1_name) values ('A');
-- Things go wrong here:
insert into table2 (table1_name) select 'A';
Actual Results:
On OS X: hangs indefinitely
On Linux: mclient abruptly terminates, without explanation.
Expected Results:
Would have expected to insert a value into the table.

I mentioned Oct2010 as a working version; Mar2011 (v11.1.1) does not have the bug either, and works fine.
But Apr2011SP2 (v11.3.5) does have the bug as well.
