Watch Out for CFQUERYPARAM and Garbage Collection

By barneyb on July 9, 2008

In the past few months I've spent a fair amount of time doing large data transformations for a couple projects, in to and out of MSSQL databases. In both projects, I've ended up refactoring my code to eliminate CFQUERYPARAM on oft-run queries, because it seems to leak memory (yes, I have debugging disabled), as [...]

CFUNITED Day One

By barneyb on June 19, 2008

As is typically the case, CFUNITED has a pair of themes.Â There's the conference theme, which, as always, is helping CF coders become more empowered by learning about new things (OO, using CFCs, learning frameworks, etc.), and then there's the "backtheme".Â This year it's all don't use only CF.Â Adobe's integrating Hibernate into CF9, Railo [...]

CF Groovy

By barneyb on June 6, 2008

Those of you who remember CF Rhino will recognize the name for my latest little project. I whipped up a small proof-of-concept integration for Groovy into CF apps tonight while playing with some classloading issues within Groovy itself.
Groovy has a number of advantages for this type of integration of JavaScript, the biggest one being [...]

Use ColdFusion? Use Java.

By barneyb on May 8, 2008

If you use ColdFusion (or another Java-based CFML runtime), you should be using Java. There's a reason that CF uses Java under the hood: Java is incredibly powerful. Yes the interface to Java from the CF level is cumbersome and creating hybrid CF/Java applications pretty much costs you CF's RAD capabilities, but there [...]

IndentXml CF UDF

By barneyb on May 1, 2008

I had a need to fix indentation of some XML today, and a quick Googling didn't turn up much help. So I wrote a little UDF that will take an XML string and return it with all the tags nicely indented:

Get Your ColdSpring (et al)!

By barneyb on April 17, 2008

For those of you not in the know, ColdSpring is a port of the Spring framework (for Java) to ColdFusion.Â It provides an Inversion of Control (IoC) framework and an Aspect Oriented Programming (AOP) container for CFCs.Â If you used stateful CFCs, you should be using ColdSpring.Â Period.
But that's not why I'm writing.
I am absolutely [...]

Build-Time Aggregation of JS/CSS Assets

By barneyb on April 8, 2008

Ben Nadel posted about compiling multiple linked files (JS/CSS) into a single file this morning, and he does it at runtime. I commented about doing it at build-time instead, and a couple people were wondering more, so here's a brief explaination.
The first part is a properties file (which can be read by both Ant [...]

S3 is Sweet (One App Down)

By barneyb on April 7, 2008

This weekend I ported my big filesystem-based app to S3, and it went like a dream. It's a image-management application, with all the actual images stored on disk. In addition to the standard import/edit/delete, the app provides automatic on-the-fly thumbnail generation, along with primitive editing capabilities (crop, resize, rotate, etc.). With images [...]

Dummy Queries in ColdFusion 8.0.1

By barneyb on April 4, 2008

Brian Rinaldi posted on his blog about dummy queries in CF 8.0.1, and it struck me as a weird solution. So here's a drop-in replacement, that I think works in a more reasonable fashion, and doesn't have any dependency on an existing DSN.
<cffunction name="dummyQuery2″ access="public" output="false" returntype="query">
<cfargument name="queryData" type="struct" required="true" />
