Wei Yan created DIRSERVER-1882:
----------------------------------
Summary: KertabEncoder.write() method should take into account the
size of the entries list to determine the buffer size
Key: DIRSERVER-1882
URL: https://issues.apache.org/jira/browse/DIRSERVER-1882
Project: Directory ApacheDS
Issue Type: Bug
Components: core
Affects Versions: 2.0.0-M14
Reporter: Wei Yan
Currently {{KeytabEncoder.write()}} always allocate 512 bytes as the buffer
size, and doesn't consider the entities list size.
{code}
ByteBuffer write( byte[] keytabVersion, List<KeytabEntry> entries )
{
ByteBuffer buffer = ByteBuffer.allocate( 512 );
putKeytabVersion( buffer, keytabVersion );
putKeytabEntries( buffer, entries );
buffer.flip();
return buffer;
}
{code}
For each entity, {{KeytabEncoder.putKeytabEntry()}} allocates 100 buffer size.
{code}
private ByteBuffer putKeytabEntry( KeytabEntry entry )
{
ByteBuffer buffer = ByteBuffer.allocate( 100 );
......
}
{code}
This mechanism fails when we create multiple principals in one keytab file.
{{KeytabEncoder.write()}} method should take into account the size of entries
list to determine the buffer size. And a reasonable max size (100 currently)
per entry must be determined.
