Bug#15776: 32-bit signed int used for length of blob
Based on contributed patch from Martin Friebe, CLA from 2007-02-24.
The parser lacked support for field sizes after signed long,
when it should extend to 2**32-1.
Now, we correct that limitation, and also make the error handling
consistent for casts.
mysql-test/r/type_blob.result:
Verify that blobs may be created with the size that is already
documented.
Additionally, test the limits of several other types.
mysql-test/t/type_blob.test:
Verify that blobs may be created with the size that is already
documented.
Additionally, test the limits of several other types.
sql/field.cc:
atoi() insufficient to gauge the length of some fields. Change
it to strtoul().
sql/item_create.cc:
atoi() insufficient to gauge the length of some fields. Change
it to strtoul().
If a casted length is too long, raise an error.
sql/share/errmsg.txt:
Change ER_TOO_BIG_FIELDLENGTH so that it can accept sizes larger
than 2**15 -- instead, 2**32.
sql/sql_yacc.yy:
Make lengths take, in addition to NUM, LONG_NUM, ULONGLONG_NUM,
and DECIMAL_NUM.
sql/unireg.h:
Define new constant.
