Support for TDE

[grtjn]

Includes inserting and validating templates. http://docs.marklogic.com/tde

These get uploaded to the schemas database. Seems to make sense to attach to deploy schema, but might require specific logic..

[grtjn]

Similar like I commented on #645, might be worth auto-detecting file format based on introspection. XML has this at the root: <template xmlns="http://marklogic.com/xdmp/tde">, and JSON must have something similar..

[grtjn]

Hmm, thought.. how about doing the introspection after loading in schema db using xqy or sjs?

Not the prettiest code, but this seemed to work:

  def deploy_schemas
    original_deploy_schemas
    logger.info "Generating TDE templates for models:"
    r = execute_query(
      %Q{
        xquery version "1.0-ml";
        import module namespace es = "http://marklogic.com/entity-services" at "/MarkLogic/entity-services/entity-services.xqy";
        import module namespace tde = "http://marklogic.com/xdmp/tde" at "/MarkLogic/tde.xqy";
        for $entity-doc-uri as xs:string? in cts:uris((), (), cts:directory-query("/entities/", "infinity"))
        let $t := es:extraction-template-generate(fn:doc($entity-doc-uri))
        let $path := fn:substring-before($entity-doc-uri, ".json") || ".xml"
        return (
          $entity-doc-uri,
          tde:template-insert($path, es:extraction-template-generate(fn:doc($entity-doc-uri)))
        )
      },
      { :db_name => @properties["ml.content-db"] }
    )
    r.body = parse_body r.body
    logger.info r.body
    logger.info ""

    logger.info "Applying custom TDE templates:"
    query = File.read ServerConfig.expand_path("#{@@path}/../tde/tdeDataStore.xqy")
    r = execute_query(
      query,
      { :app_name => @properties["ml.app-name"] }
    )
    r.body = parse_body r.body
    logger.info r.body
    logger.info ""

    change_permissions(@properties["ml.schemas-db"])
  end
