Subject [jira] Closed: (DIRSERVER-599) Can't compile long schema
Date Sun, 27 Aug 2006 14:56:23 GMT
     [ ]

Alex Karasulu closed DIRSERVER-599.

    Fix Version/s: 1.0-RC4
       Resolution: Won't Fix

won't fix: we have a workaround (break up large schemas).  This is fine temporarily until
we revamp the schema subsystem in 1.1.

> 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:\\apacheds-1.0\core\target\classes
> [INFO] ----------------------------------------------------------------------------
> [INFO] ----------------------------------------------------------------------------
> [INFO] Compilation failure
> c:\\apacheds-1.0\core\target\generated-sources\org\apache\directory\server\core\schema
> \bootstrap\[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.
