MySQL Bugs: #3473: blank host in tables_priv or collumns

Bug #3473	blank host in tables_priv or collumns_priv
Submitted:	14 Apr 2004 16:14	Modified:	28 Apr 2004 15:33
Reporter:	Brian Nelson
Status:	Closed
Category:	Server	Severity:	S3 (Non-critical)
Version:	4.0.18	OS:	Sun Solaris (Solaris 9 sparc)
Assigned to:	Bugs System	Target Version:

Description:
Trying to use a blank host value for table-specific or collumn-specific privileges does
not work as expected. Using a blank value results in non-working privilege. Using a '%'
for the host value does work as expected. These should be equivalant values, according to
secion 5.4.6 of the documentation.

How to repeat:
Create a user with only 'usage' privilege on a database. Then assign a table or
collumn-specific privilege to the user, with a blank host value in tables_priv or
collumns_priv. The user will not have the expected privilege.

Change the blank value to a '%' and the privilege will work as expected.

Please note that the user in question has a blank host value in the 'user' table as well
(ie for the 'consult the host table' behavior).

FYI This happens on v 3.23.58 as well

Verified with 4.0.18 and 4.1.2:

GRANT ALL ON test.t1 TO testuser@'';
SHOW GRANTS FOR testuser@'';
FLUSH PRIVILEGES;
SHOW GRANTS FOR testuser@'';
