[MDEV-12361] The MariaDB Server never returns to client after a read error - Jira

Having the CSV file foo.csv (attached):

26,Hello world!,foo

45,abcdefghijklmnopqrstuvwxyz,bar

The table:

create table t1 (

n int not null,

m char(20),

t char(20))

engine=connect table_type=CSV file_name='foo.csv';

When doing:

select * from t1;

The server does not return or is interrupted after a long timeout.

This because of a read error on the second record, field 2 being too long for the column m.

However, working on bar.csv (attached):

45,abcdefghijklmnopqrstuvwxyz,bar

26,Hello world!,foo

with the table:

create table t2 (

n int not null,

m char(20),

t char(20))

engine=connect table_type=CSV file_name='C:/Data/FMT/bar.csv';

when executing:

select * from t2;

The proper error message is returned:

1296: Got error 122 'Field 2 too long for m line 1 of bar.csv' from CONNECT
