Version 1.4.0-rc1

• Split semantics of hopobject["property"] and hopobject.get("childname"). The first will only return properties, while the latter will only return child objects whereas before, the two were largely synonymous.
• Improve Rhino error reporting: Always print an error message if something inside a prototype is broken.
• Allow raw, un-prototyped JavaScript objects as macro and action handlers
• HopObject.remove(HopObject) is renamed to HopObject.removeChild(HopObject) and does not actually delete the child object from db, but just releases it from the parent. HopObject.remove() without argument is used to delete the object.
• Rename res.pushStringBuffer() and res.popStringBuffer() to res.push() and res.pop()
• Add HopObject.getById() to retrieve a child object by ID regardless of its accessname
• Switch to Jakarta Commons Logging and adapt our own logging classes to fit in
• Add collection.logicalOperator=AND|OR|XOR in type.properties to allow setting the logical operator for combining multiple constraints on collections and references.
• Implement aggressive loading of object references. If object.loadmode = aggressive is set for an object reference, the objects will always be loaded in one join query with the referring object. Works now also for Oracle < 9.
• Implement parsed filters in type.properties that allows to include values from the current object in a collection's filter string:
  collection.filter = foreign_column_1 = ${local_column_2}
• Add collection.filter.additionalTables to allow to include other tables in the select string's FROM part. This is useful in conjunction with the parsed filters feature.
• Add support for SQL query hints by using the folliwing in type.properties:
  _children.hints = /*+ INDEX(table_name, index_name) */
• Include classes from classpath in Helma's ClassLoader. Allow them to be excluded using the -Dhelma.exludeSystemClasses=true switch
• Use upper case prototype names such as Root, User, HopObject by default, but remain compatible with lower case names
• Add two options for application entries in apps.properties for directory indices and index pages:
  <app>.staticIndex = true
  <app>.staticHome = index.html, default.htm
  Default values are (false) for directory listings and "index.html, index.htm" for index pages.
• Add CommandlineRunner class to execute a function from a Helma application from command line. The command line syntax is
  java helma.main.launcher.Commandline appname.functionname
• Add experimental res.forward() to forward a request to a local (static) resource. The base resource must be mounted as <app>.protectedStatic in the apps.properties file.
• Add rootId application property to set the id of the root object to something else then 0
• Fix and improve line break encoding in format() functions.
• Add formatParagraphs() that uses

  tags rather than
  to encode line breaks

• Lots and lots of fixes on the objectmodel/persistance code
• Lots and lots of fixes in Rhino scripting engine prototype handling
• Various fixes in Mail object
• Implement Xml.get() and Xml.getFromString(), which have been missing
• Add dispose() function to Image object to aid immediate garbage collection
• Add application/text to MIME types recognized as text
• Return an ordinary JavaScript Array from HopObject.list() rather than a wrapped Java array
• Implement HopObject.ist(start, length) to return a slice from the object's child objects
• Allow character codings other than ISO-8859-1 in text inputs of multipart/form-data (file upload) forms
• Implement hrefSkin and hrefFunction in app.properties, which have been missing
• Disable check if a port we're trying to listen to is already in use, so the failure will be slightly less elegant
• Disable Response compression as this is not available on Jetty 4.2
• Add Unix/Linux service startup script to distribution
• Upgrade to Jetty 4.2.17
• Upgrade to Rhino ~ 1.5 Release 5 (CVS snapshot from 2004/02/11)
• Make Helma compile on Java 1.5
