Compatibility –Language & Syntax

Railo 4.2


Railo 4.2 – Language & Syntax

• New tag notation in cfscript• Before:• <cfloop from="1" to="10" index="i">• Became• loop from="1" to="10" index="i" { … }• Now becomes:• cfloop(from:1, to:10, index:"i") { … }



• Member functions on literals:– [1,2,3,4].each( function() {} );– {key:value}.keyExists(…);– query(col:[1,2,3,4]).addRow(1);– "This is a string".len()– "susi,peter,john,doe".listToArray();



• Subscript Operator – Use a String like an Array– Instead of:

mid("susi“, 3, 1)– You can now write:

susi[3]

Better performance and shorter syntax


Railo 4.2 – New functionality

• All above except *reduce support the argument "parallel" and "maxThreads"

Type

Function

Array Collection List Struct QueryEvery

Map

Reduce

Some

Each



• New member function isEmpty()

• "".isEmpty(), [].isEmpty(), {}.isEmpty()• Function len() now supports all types

Type Condition returning trueQueries record count = 0Arrays arrayLen = 0Structs key count = 0Strings empty string



• CFHTTP contains a new key in the resultcalled cookie

• CFFILE and CFDIRECTORY allow you tocreate the directory if it does not exist

• getCanonicalPath()– Converts

c:\this\is/a/path\..\..\susi\peterintoc:\this\is\susi\peter

Administrator Changes

Railo 4.2


Railo 4.2 – Administrator improvements

• Disabling Type checking• Lots of settings move to the

Application.cfc• Hints for the usage of these settings• Export page• New logging page

New Concepts

Railo 4.2


Railo 4.2 – New concepts

• Application.cfc– Can be used for almost EVERY setting

possible in the Railo Web Administrator– Generate export for an Application.cfc in

the administrator



• Problem– How do you differenciate settings

between environment & test?– How do you influence the standard

behaviour?– Ever forgotten to use the attribute

addtoken?



• Application.cfc allows you to definestandard values for ANY attribute– Influence display of CFDUMP– Influence mailservers or database defaults



• Current implementation supports SOAP– International Standard– Transport protocol, very flexible– supported by all programming languages

• BUT– Bloated XML format– Takes lots of time for conversion & serialization


HTTP - Webservices

• HTTP Webservices– Very lightweight– Very fast– Railo specific ATM

– Autodetection of Railo HTTP Webservices

The future of CFML

Railo 5.0


Railo 5.0

What is the focus?• Performance• Stability• Language improvements• Ease of use

Architecturalchanges

Railo 5.0 – Main features


Railo 5.0

• Current problem– An application needs a JAR file, but the

JAR file collides with an existing one– Updating JAR libaries– No way to manage jar libaries

programmatically

• Architectural changes• Syntax changes• Component enhancements• Java interaction• Improved extendibility


Railo 5.0 – Architectural changes

• Solution: OSGi– Open Service Gateway initiative (2000)– A framework that manages libraries

(bundles and versions)– Allows you to load libraries in different

versions, all at the same time




• OSGi in Railo 5.0– COMPLETE rewrite of the architecture– Enterprise market requirement– Everything in Railo 5.0 is OSGi

• Core• Extensions• JAR files




• OSGi in Railo 5.0– Better stability– Higher performance– All libraries used by Railo are bundles– Possible to load/unload and start/stop

any library at any time




• OSGi in Railo 5.0– New set of functions that allow you to the power of this

new functionality

// load a class in a specific versiondtf=javaLoad(bundle:"org-joda-time", version:"2.1.0", class:"org.joda.time.format.DateTimeFormat“

);




• OSGi in Railo 5.0– New set of functions// load a class in a specific versiondtf=javaLoad(bundle:"org-joda-time", version:"2.1.0", class:"org.joda.time.format.DateTimeFormat“

);or

oJavaClass = createJavaProxy(className, jarFile, OSGi bundle, version of the OSGi bundle);



JSR 223

• Wikipedia says: "JSR 223 is a framework forembedding scripts into Java source code"

• Oracle already included Javascript as of Java 6

• Can be called from the command line like:>jrunscript something.js



JSR 223

• Why not be able to call:>jrunscript –f cfml commandbox/Bootstrap.cfm

Or>jrunscript –f cfml

cfml>fileCopy(source, destination)cfml>

• Might have a bigger impact on CommandBox


Syntax changes



Railo 5.0 – Syntax Changes

• Introduction of Lambda functions– Shorhand notation for closures– Check out the example

• Further operators & operatoroverloading



Syntax Changes

• New accessors for component members• Try this:

component {this.displayName = "myCmpn";private this.version = "1.0";static {

private static.susi = 1;}

}• Architectural changes• Syntax changes• Component enhancements• Java interaction• Improved extendibility


Syntax changes

• Component iterators:– By implementing the methods:

• _hasNext(), _next(), _reset()

– You now can do:

oObjList = new someObjList("customers");for(oCustomer in oCustomerList) {

oCustomer.raiseInvoice();}



Syntax changes

• New type of variable declarationvar qry, susi, peterorlocal.qry, local.susi, local.peter

Is equal to:var qry = null;var susi = null;var peter = null;

orvar qry = ""var susi = ""var peter = ""



Syntax changes

• New type of variable declarationvar susi=4, var peter = 6, var qry = 7;

Or of course:

local.susi=4, local.peter = 6, local.qry = 7;



Inline components

• Now it is possible to define helpercomponents within one line:

// Closure componentsoMyComponent = component {

function getData() {

}};

oMyComponent.getData();


Componentenhancements



Component enhancements

• Current problem– creating components either as singletons

or transients– No way for transients to store global data

valid for all instances of the component




• New keyword: static– Allows you to define

• a static constructor• static data, shared amongst ALL instances of

the SAME component• Static functions

– For static functions a new operator isdefined

• MyComponent::myStaticFunction();• Architectural changes• Syntax changes• Component enhancements• Java interaction• Improved extendibility



• Abstract and final components andfunctions– Abstract components & functions have to

be inherited– Much better to use than interfaces– Final components & functions can not be

inherited




• Inline components– Usable for very simple components– Saves file operations– Increase in performance– Allows definition of multiple components

in ONE cfc



Component casters

• Existing ones– _toString()– _toNumeric()– _toDateTime()– _toBoolean()

• New ones– _toStruct()– _toArray()– _toQuery()– _toJSON()




• Operators– _compare(obj): number– _contains(obj): boolean

• Allows you to do:oObj = new someObj();oObj2 = new someOtherObj();if (oObj gt oObj2) {}

Or

oObj.append(); // for arrays• Architectural changes• Syntax changes• Component enhancements• Java interaction• Improved extendibility

Java interaction



Java enhancements

• component extendsjava="java.io.file"• cfscript language="java"• call Railo directly from java• Interaction with java code• Drop Java Reflection



Scripting support JSR 223

• Allows executing any script type insidea cfscript type– Groovy– Scala– Javascript– Python– Ruby, etc.


Improvedextendibility



Improved extendibility

• New way to write extensions– Convention based– Auto deployment possible

• You simply drop files into a certain folder– Manifest file

• Contains metadata of an autodeploy extension• Dependencies between extensions• Preconditions (e.g. requires Railo 5.0)

Railo 5 will do the rest…• Architectural changes• Syntax changes• Java interaction• Component enhancements• Improved extendibility

Be producive!

Rasia Tools


Applications – Problem

• Every application collects data fromexternal resources

• Depending on cache settings, data isconstantly requested or not

• There is no real overview of what dataa server requests from any externalresources


Possible solution

• Idea for a tool:– When enabled, checks all external

resources, whether the data has changedsince the last access

– Determines dependencies (session, application, independent)

– Displays potential cache candidates– Allow the user to select which candidate

data to cache and for how long


Possible solution

• Analyzing data (eg. Queries)– Get the input parameters (SQL,

Datasource, Session, Application etc.) determine entry hHash

– Analyze the result (determinedependency & resulthash)

– Store the change interval and themetadata

Say "hello" to

Booster

Rasia Tools


Rasia – Booster

• Caching of – Queries– Functions– Includes– HTTP calls– Files, Directories– Web Service Calls– Etc.


Rasia – Booster

• Apply rules– At the moment makes use of

cachedWithin="smart"– If there is a rule for this inputHash, apply

the rule according to the selection– Store statistics– Activate boost!!!


Rasia – Boost UI

• Implemented as a Railo Admin plugin• Offers overview for Entries, Rules• Several Statistics and time estimates

• Rasia Boost is available of course forRailo 5.x

• But why not…


Rasia – Tools

• Make Boost available for ANY JVM application?– Groovy– Native Java app– ColdFusion


JVM - Boost

First project along the way:

Say "hello" to

ICF

Rasia Tools


Rasia – ICF

• Railo > 3.0 allows you to use different kinds of Cache providers– Local or remote– Clustered or not

• ACF is only able to talk to EHCache– Local– and with a tougher configuration remote


Rasia – ICF

• ICF allows you to use– Infinispan– With ColdFusion 9, 10 and 11– By using the usual functions

• CacheGet()• CachePut()• CacheDelete(), etc.


Rasia – ICF

• We created an Installer for ACF• Allows you to install Extensions just like

the extension provider in Railo• Will be released as a separate product


Installer
