Subject [jira] Created: (DIRSERVER-599) Can't compile long schema
Date Mon, 13 Mar 2006 19:09:19 GMT
Can't compile long schema
-------------------------

         Key: DIRSERVER-599
         URL: http://issues.apache.org/jira/browse/DIRSERVER-599
     Project: Directory ApacheDS
        Type: Bug
  Components: schema-plugin  
    Versions: 1.0-RC1    
    Reporter: Endi S. Dewata


Currently the schema plugin converts a schema into Java files, and if the schema gets too
long the Java file can't be compiled. Some applications might use a huge schema, for instance
the default Active Directory schema contains more than 1000 attribute types. Compiling such
schema will produce the following error:

[INFO] Generating activeDirectory schema.
[INFO] [resources:resources]
[INFO] Using default encoding to copy filtered resources.
[INFO] [compiler:compile]
Compiling 14 source files to c:\svn.apache.org\apacheds-1.0\core\target\classes
[INFO] ----------------------------------------------------------------------------
[ERROR] BUILD FAILURE
[INFO] ----------------------------------------------------------------------------
[INFO] Compilation failure

c:\svn.apache.org\apacheds-1.0\core\target\generated-sources\org\apache\directory\server\core\schema
\bootstrap\ActiveDirectoryAttributeTypeProducer.java:[52,16] code too large

A workaround is that the schema can be split into several smaller schemas, this will produce
smaller Java files which can be compiled just fine. From experiments it seems that the compiler
will hit the limit when compiling 622 attribute types. This will produce more than 11k lines
of  code in the produce() method in the generated Java file. A similar limit may also affect
the max number of object class definitions.
