Called upon deserialization for restoring the state of this SystemPrincipal from a stream.

Throws:

java.io.IOException

java.lang.ClassNotFoundException

Serialized Fields

name

java.lang.String name

The name of the principal.

Note that the name is not a "normalized" Authorization Identifier. This is due to peculiarities of the Java Security Runtime, which compares a javax.security.auth.Subject's Principals against the literal Principal name as declared in the policy files, and not against the return value of method getName(). So, a normalization of names within SystemPrincipal doesn't affect permission checking by the SecurityManager.

In order for a javax.security.auth.Subject to be granted permissions on the basis Authorization Identifier rules, e.g., for a Subject authenticated as edWard to fall under a policy clause declared for EDWARD, the Subject has to be constructed (or augmented) with both the literal name and the normalized Authorization Identifier.

As an alternative approach, class SystemPrincipal could implement the non-standard interface com.sun.security.auth.PrincipalComparator, which declares a method implies(Subject) that would allow for Principals to match Subjects on the basis of normalized Authorization Identifiers. But then we'd be relying upon non-standard Security Runtime behaviour.

For triggers, 3 possible scenarios 1)referencedColumns is not null but referencedColumnsInTriggerAction is null - then following will get read referencedColumns.length individual elements from referencedColumns arrary eg create trigger tr1 after update of c1 on t1 for each row values(1); 2)referencedColumns is null but referencedColumnsInTriggerAction is not null - then following will get read -1 -1 referencedColumnsInTriggerAction.length individual elements from referencedColumnsInTriggerAction arrary eg create trigger tr1 after update on t1 referencing old as oldt for each row values(oldt.id); 3)referencedColumns and referencedColumnsInTriggerAction are not null - then following will get read -1 referencedColumns.length individual elements from referencedColumns arrary referencedColumnsInTriggerAction.length individual elements from referencedColumnsInTriggerAction arrary eg create trigger tr1 after update of c1 on t1 referencing old as oldt for each row values(oldt.id); Scenario 1 for triggers is possible for all different releases of dbs ie both pre-10.7 and 10.7(and higher). But scenarios 2 and 3 are only possible with database at 10.7 or higher releases. Prior to 10.7, we did not collect any trigger action column info and hence referencedColumnsInTriggerAction will always be null for triggers created prior to 10.7 release.

For triggers, 3 possible scenarios 1)referencedColumns is not null but referencedColumnsInTriggerAction is null - then following gets written referencedColumns.length individual elements from referencedColumns arrary eg create trigger tr1 after update of c1 on t1 for each row values(1); This can also happen for a trigger like following if the database is at pre-10.7 level. This is for backward compatibility reasons because pre-10.7 releases do not collect/work with trigger action column info in system table. That functionality has been added starting 10.7 release eg create trigger tr1 after update on t1 referencing old as oldt for each row values(oldt.id); 2)referencedColumns is null but referencedColumnsInTriggerAction is not null - then following gets written -1 -1 referencedColumnsInTriggerAction.length individual elements from referencedColumnsInTriggerAction arrary eg create trigger tr1 after update on t1 referencing old as oldt for each row values(oldt.id); 3)referencedColumns and referencedColumnsInTriggerAction are not null - then following gets written -1 referencedColumns.length individual elements from referencedColumns arrary referencedColumnsInTriggerAction.length individual elements from referencedColumnsInTriggerAction arrary eg create trigger tr1 after update of c1 on t1 referencing old as oldt for each row values(oldt.id);

                   throws java.io.IOException

Writes a non-Clob data value to the modified UTF-8 format used by Derby. The maximum stored size is based upon the UTF format used to stored the String. The format consists of a two byte length field and a maximum number of three bytes for each character.
This puts an upper limit on the length of a stored String. The maximum stored length is 65535, these leads to the worse case of a maximum string length of 21844 ((65535 - 2) / 3).
Strings with stored length longer than 64K is handled with the following format: (1) 2 byte length: will be assigned 0. (2) UTF formated string data. (3) terminate the string with the following 3 bytes: first byte is: +---+---+---+---+---+---+---+---+ | 1 | 1 | 1 | 0 | 0 | 0 | 0 | 0 | +---+---+---+---+---+---+---+---+ second byte is: +---+---+---+---+---+---+---+---+ | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | +---+---+---+---+---+---+---+---+ third byte is: +---+---+---+---+---+---+---+---+ | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | +---+---+---+---+---+---+---+---+ The UTF format: Writes a string to the underlying output stream using UTF-8 encoding in a machine-independent manner.

First, two bytes are written to the output stream as if by the writeShort method giving the number of bytes to follow. This value is the number of bytes actually written out, not the length of the string. Following the length, each character of the string is output, in sequence, using the UTF-8 encoding for the character.

Throws:

java.io.IOException - if an I/O error occurs.

Although we are not expected to be persistent per se, we may be written out by the sorter temporarily. So we need to be able to write ourselves out and read ourselves back in. We rely on formatable to handle situations where value is null.

Why would we be called to write ourselves out if we are null? For scalar aggregates, we don't bother setting up the aggregator since we only need a single row. So for a scalar aggregate that needs to go to disk, the aggregator might be null.

java.lang.String databaseName

Stores the relational database name, RDBNAME. The length of the database name may be limited to 18 bytes and therefore may throw an SQLException.

description

java.lang.String description

portNumber

int portNumber

serverName

java.lang.String serverName

user

java.lang.String user

This property can be overwritten by specifing the username parameter on the DataSource.getConnection() method call. If user is specified, then password must also be specified, either in the data source object or provided on the DataSource.getConnection() call. Each data source implementation subclass will maintain it's own password property. This password property may or may not be declared transient, and therefore may be serialized to a file in clear-text, care must taken by the user to prevent security breaches. Derby-406 fix

securityMechanism

short securityMechanism

Security Mechanism can be specified explicitly either when obtaining a connection via a DriverManager or via Datasource. Via DriverManager, securityMechanism can be set on the connection request using the 'securityMechanism' attribute. Via DataSource, securityMechanism can be set by calling setSecurityMechanism() on the ClientDataSource If the security mechanism is not explicitly set as mentioned above, in that case the Client will try to upgrade the security mechanism to a more secure one, if possible. See BasicClientDataSource40.getUpgradedSecurityMechanism(java.lang.String). Therefore, need to keep track if the securityMechanism has been explicitly set.
