New getSubString() handling in ClobProxy is incompatible with MySQL JDBC PS.setClob(int,
Clob) for empty CLOB
-------------------------------------------------------------------------------------------------------------
Key: HHH-5704
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5704
Project: Hibernate Core
Issue Type: Bug
Affects Versions: 3.6.0
Environment: MySQL JDBC 5.1.12 / 5.1.13
Reporter: Sergey Vladimirov
For all empty but not-null CLOBs MySQL drivers do the following
(com.mysql.jdbc.PreparedStatement):
String forcedEncoding = this.connection.getClobCharacterEncoding();
if (forcedEncoding == null) {
setString(i, x.getSubString(1L, (int) x.length()));
} else {
try {
setBytes(i, x.getSubString(1L,
(int)x.length()).getBytes(forcedEncoding));
} catch (UnsupportedEncodingException uee) {
throw SQLError.createSQLException("Unsupported character encoding " +
forcedEncoding, SQLError.SQL_STATE_ILLEGAL_ARGUMENT, getExceptionInterceptor());
}
}
As you can see, getSubString is called with first argument (start) equal to 1, even if
length of CLOB is 0. Of course, it's not very good, but it worked for previous
versions of Hibernate. But in 3.6.0 getSubString() handling in ClobProxy introduces
additional checks that prevents the code above from working:
if ( start > getLength() ) {
throw new SQLException( "Start position [" + start + "] cannot exceed
overall CLOB length [" + getLength() + "]" );
}
Thus this code will now thrown an exception if content is empty (but not null!) CLOB. Here
the part of stack trace:

Christopher G. Stach II commented on HHH-5704:
----------------------------------------------
Since it always starts at 1, start > getLength() should fail for any database driver
with an emtpy lob. The check should probably be start - 1 > getLength() and possibly
even an additional check for start + length - 1 > getLength() to avoid overruns.

New subject: [Hibernate-JIRA] Updated: (HHH-5704) New getSubString() handling in ClobProxy is incompatible with MySQL JDBC PS.setClob(int, Clob) for empty CLOB
[
http://opensource.atlassian.com/projects/hibernate/browse/HHH-5704?page=c...

Gail Badner updated HHH-5704:
-----------------------------
Fix Version/s: 4.0.0.Alpha1
3.6.1
New getSubString() handling in ClobProxy is incompatible with MySQL
JDBC PS.setClob(int, Clob) for empty CLOB
-------------------------------------------------------------------------------------------------------------
Key: HHH-5704
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5704
Project: Hibernate Core
Issue Type: Bug
Affects Versions: 3.6.0
Environment: MySQL JDBC 5.1.12 / 5.1.13
Reporter: Sergey Vladimirov
Fix For: 3.6.1, 4.0.0.Alpha1
Attachments: hibernate-3.6.0-HHH-5704.patch
For all empty but not-null CLOBs MySQL drivers do the following
(com.mysql.jdbc.PreparedStatement):
String forcedEncoding = this.connection.getClobCharacterEncoding();
if (forcedEncoding == null) {
setString(i, x.getSubString(1L, (int) x.length()));
} else {
try {
setBytes(i, x.getSubString(1L,
(int)x.length()).getBytes(forcedEncoding));
} catch (UnsupportedEncodingException uee) {
throw SQLError.createSQLException("Unsupported character encoding " +
forcedEncoding, SQLError.SQL_STATE_ILLEGAL_ARGUMENT, getExceptionInterceptor());
}
}
As you can see, getSubString is called with first argument (start) equal to 1, even if
length of CLOB is 0. Of course, it's not very good, but it worked for previous
versions of Hibernate. But in 3.6.0 getSubString() handling in ClobProxy introduces
additional checks that prevents the code above from working:
if ( start > getLength() ) {
throw new SQLException( "Start position [" + start + "] cannot exceed
overall CLOB length [" + getLength() + "]" );
}
Thus this code will now thrown an exception if content is empty (but not null!) CLOB.

This may be fixed by HHH-5706.
Can someone try checking out code from 3.6 and see if it is fixed?

New getSubString() handling in ClobProxy is incompatible with MySQL
JDBC PS.setClob(int, Clob) for empty CLOB
-------------------------------------------------------------------------------------------------------------
Key: HHH-5704
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5704
Project: Hibernate Core
Issue Type: Bug
Affects Versions: 3.6.0
Environment: MySQL JDBC 5.1.12 / 5.1.13
Reporter: Sergey Vladimirov
Fix For: 3.6.1, 4.0.0.Alpha1
Attachments: hibernate-3.6.0-HHH-5704.patch
For all empty but not-null CLOBs MySQL drivers do the following
(com.mysql.jdbc.PreparedStatement):
String forcedEncoding = this.connection.getClobCharacterEncoding();
if (forcedEncoding == null) {
setString(i, x.getSubString(1L, (int) x.length()));
} else {
try {
setBytes(i, x.getSubString(1L,
(int)x.length()).getBytes(forcedEncoding));
} catch (UnsupportedEncodingException uee) {
throw SQLError.createSQLException("Unsupported character encoding " +
forcedEncoding, SQLError.SQL_STATE_ILLEGAL_ARGUMENT, getExceptionInterceptor());
}
}
As you can see, getSubString is called with first argument (start) equal to 1, even if
length of CLOB is 0. Of course, it's not very good, but it worked for previous
versions of Hibernate. But in 3.6.0 getSubString() handling in ClobProxy introduces
additional checks that prevents the code above from working:
if ( start > getLength() ) {
throw new SQLException( "Start position [" + start + "] cannot exceed
overall CLOB length [" + getLength() + "]" );
}
Thus this code will now thrown an exception if content is empty (but not null!) CLOB.

New getSubString() handling in ClobProxy is incompatible with MySQL
JDBC PS.setClob(int, Clob) for empty CLOB
-------------------------------------------------------------------------------------------------------------
Key: HHH-5704
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5704
Project: Hibernate Core
Issue Type: Bug
Affects Versions: 3.6.0
Environment: MySQL JDBC 5.1.12 / 5.1.13
Reporter: Sergey Vladimirov
Assignee: Gail Badner
Fix For: 3.6.1, 4.0.0.Alpha1
Attachments: hibernate-3.6.0-HHH-5704.patch
For all empty but not-null CLOBs MySQL drivers do the following
(com.mysql.jdbc.PreparedStatement):
String forcedEncoding = this.connection.getClobCharacterEncoding();
if (forcedEncoding == null) {
setString(i, x.getSubString(1L, (int) x.length()));
} else {
try {
setBytes(i, x.getSubString(1L,
(int)x.length()).getBytes(forcedEncoding));
} catch (UnsupportedEncodingException uee) {
throw SQLError.createSQLException("Unsupported character encoding " +
forcedEncoding, SQLError.SQL_STATE_ILLEGAL_ARGUMENT, getExceptionInterceptor());
}
}
As you can see, getSubString is called with first argument (start) equal to 1, even if
length of CLOB is 0. Of course, it's not very good, but it worked for previous
versions of Hibernate. But in 3.6.0 getSubString() handling in ClobProxy introduces
additional checks that prevents the code above from working:
if ( start > getLength() ) {
throw new SQLException( "Start position [" + start + "] cannot exceed
overall CLOB length [" + getLength() + "]" );
}
Thus this code will now thrown an exception if content is empty (but not null!) CLOB.

I believe there should be additional check like:
long start = (Long) args[0];
if ( start < 1 ) {
throw new SQLException( "Start position 1-based; must be 1 or more."
);
}
int length = (Integer) args[1];
if ( length < 0 ) {
throw new SQLException( "Length must be great-than-or-equal to zero."
);
}
// workaround for MySQL incompatibility
if ( start == 1 && length == 0) {
return "";

throw new SQLException( "Start position [" + start + "] cannot exceed
overall CLOB length [" + getLength() + "]" );

New subject: [Hibernate-JIRA] Commented: (HHH-5704) New getSubString() handling in ClobProxy is incompatible with MySQL JDBC PS.setClob(int, Clob) for empty CLOB

By the way, Fixed Hibernate 3.6.6 Jar is still available for downloading.
New getSubString() handling in ClobProxy is incompatible with MySQL
JDBC PS.setClob(int, Clob) for empty CLOB
-------------------------------------------------------------------------------------------------------------
Key: HHH-5704
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5704
Project: Hibernate Core
Issue Type: Bug
Affects Versions: 3.6.0
Environment: MySQL JDBC 5.1.12 / 5.1.13
Reporter: Sergey Vladimirov
Assignee: Gail Badner
Fix For: 3.6.1, 4.0.0.Alpha1
Attachments: hibernate-3.6.0-HHH-5704.patch
For all empty but not-null CLOBs MySQL drivers do the following
(com.mysql.jdbc.PreparedStatement):
String forcedEncoding = this.connection.getClobCharacterEncoding();
if (forcedEncoding == null) {
setString(i, x.getSubString(1L, (int) x.length()));
} else {
try {
setBytes(i, x.getSubString(1L,
(int)x.length()).getBytes(forcedEncoding));
} catch (UnsupportedEncodingException uee) {
throw SQLError.createSQLException("Unsupported character encoding " +
forcedEncoding, SQLError.SQL_STATE_ILLEGAL_ARGUMENT, getExceptionInterceptor());
}
}
As you can see, getSubString is called with first argument (start) equal to 1, even if
length of CLOB is 0. Of course, it's not very good, but it worked for previous
versions of Hibernate. But in 3.6.0 getSubString() handling in ClobProxy introduces
additional checks that prevents the code above from working:
if ( start > getLength() ) {
throw new SQLException( "Start position [" + start + "] cannot exceed
overall CLOB length [" + getLength() + "]" );
}
Thus this code will now thrown an exception if content is empty (but not null!) CLOB.
