Re: Passing arguments into base class
You're using ColdSpring and you say CS is not autowiring the field on a base class? It's supposed to, FYI, it just is. If it does not, you can do it explicitly in your xml file (if you use the DefaultXMLBeanFactory.cfc). Also, make sure the autowire option is on, at least for this object if not for all of your beans. It's strange that it is not working, maybe this would be a question for the ColdSpring list.

However, it doesn't really work in this situation because the base class is never called directly though the beanfactory. The bean that is extending the base class may, but not the baseclass itself. This is my issue. I am actually already doing something identical to what Byron suggested, but by calling the utility class through the beanfactory (which is stored in the application scope) instead of creating a new instance of the utility class using New. In either case, the utility class variable is being explicitly called/created within the base class, not passed in as an argument.

Re: Passing arguments into base class
Dean,
Byron's suggestion is a good one, and the right way to go unless you use an
IoC container. It's an object-oriented programming idea where, when you
come to the point of not wanting to instantiate all your objects. You
invert the control of creating away from what normally creates them into
some kind of bean factory. There are a number of them out there for
ColdFusion. ColdSpring, WireBox, and DI/1 to name the big ones off the top
of my head. An ioc container/factory will keep it all internally for you,
wire your bean up, then hand you what you asked for, all ready to go.
The only other solution is to send in your utility object each time you
create something that needs it.

Thanks Byron,
I wasn't wanting my utility class to inherit my base class, I am wanting to
inject the utility class into the base class. I'm trying to get away from
explicitly defining the utility class from within the base class. Since the
base class is not called directly, I don't know how to pass the utility
class in as a required argument during initialization.

Re: postParametersLimit in CF11
I'm sorry that I don't have an answer to your question or a solution to your problem, but I just have to ask, is it possible that your application just needs to adapt to what is a fairly standard security practice across the industry? It sounds like one of those jokes that ends in just because you can, it doesn't mean you should. What is this process that forces you to submit over one thousand form fields in one POST? Perhaps you can serialize it into one big string that's parsed out on the server? You say it's for importing a spreadsheet - couldn't you import the whole spreadsheet file and use cfspreadsheet to do individual fields? I have trouble believing a user can even see 1000 items on a single page - did you set up the whole spreadsheet as a grid with form fields like a1, a2, b1, b2? Can you piecemeal it and send partials via ajax, live, as the user updates them? You don't really have to answer, as interesting as it may be, but maybe you can ask these questions internally and find some better kind of architecture to solve the problem. Good luck!

Re: # in variables
My guess is much like Tim Healt's. If you're calling a web service like a WSDL/SOAP service, the # should be fine. If you're calling it directly via URL params, like ?method=xargument1=v#riable, the # is a sign to your web server that the URL params stop there - it's a href hash, which goes to the browser not the server. If that's the case, then URL encoding on the client would be necessary. The bad news is URL encoding may pass on this because # is a valid URL parameter, just not what you want. In that case, you may have to manually replace # with %23. nathan strutz [www.dopefly.com] [about.me/nathanstrutz] On Fri, Feb 7, 2014 at 12:14 PM, Adam Cameron dacc...@gmail.com wrote: On 7 February 2014 18:07, Jon Clausen jon_clau...@silowebworks.com wrote: Bryan, For clarification, how are the comments content being evaluated by CF and causing it to choke?

Re: Trying to check if username exists in table prior to form submit
Dustin,
First things first, load your page with a javascript console or browser dev
tools and you will see that there is an error in your javascript. If it
can't compile, it can't get on to running your code and checking the
username. Hope that helps.
Also, make sure you run the same username check on the server side, after
they submit the form, because javascript can be pretty easily bypassed, or
errors like this can cause it to not validate on the client side.
Another thing, you've written a lot of jQuery to be hardcoding an onChange
event on your html input element. You can (and should) replace this:
onchange=chkUsernameUnique(this.value); with this:
$(input[name=Username]).on(change, chkUsernameUnique); - this will pass
the input in as an argument instead of the value of the input, but it
allows you to divorce your javascript from your html.

Re: CFFile Question
You can specify the local file name of the uploaded file as it is uploaded,
through the cffile tag's destination= attribute. It's like this:
cffile action=upload destination=#expandPath('.')#/#createUUID()#
filefield=postfile result=f
Good security dictates first that uploaded files should never go in the web
root (even though I'm doing that here), and also that they do not keep the
same filename. You see here that I am giving the file a uuid as its name,
but you can give it a database unique key if you have a record of your
upload, or something else. You can get the name cffile gave it through
#f.serverFile#. Track that name in your database, and the #f.clientFile#
original file name as well. In fact, just cfdump var=#f# to see all
that cffile has.

Re: Severe memory issue
I see that there are millions of objects in the memory and many of them are LoopTags and QueryTags Is that from a java thread dump or something else? The thread dump should show you everything the JVM is doing. It actually sounds like your server is busy doing a lot of things. Could it be that you just need to build your infrastructure, split your application across more servers? At the very least, tune your JVM settings to accommodate what the application is doing or bring down your active request threads in the CF admin. The improvements you mentioned, while some of them are beneficial (vars and queryparams), others are probably not (query loops to index loops). Did you try the VarScoper tool? It's amazing! It sounds like you're doing a lot of threading, which makes things faster, but also makes the server busier. Busier servers mean more things happening at once, which means you're using more memory, making your problem worse. Putting loops in cfthread won't make the loops faster; breaking off logical parts of your application into their own threads could make your application faster. Too many threads can cause memory leaks depending on what you are doing, for example, Marc Esher's cfconcurrent project discovered some big memory leaks when you do certain things with the cfconcurrent library on CF9. nathan strutz [www.dopefly.com] [hi.im/nathanstrutz] On Wed, Jan 30, 2013 at 3:27 AM, Helwig, Till Helge till.hel...@saxsys.dewrote: Hi, I'm working on a very old and very badly coded CF application at the moment. It contains servertasks that do a lot of batch processing where huge data sets are queried from a database, processed and the results written back to the DB. Unfortunately by now the jobs have become so large that we frequently get heap space errors. I'm trying to figure out why the process takes up so much memory and I've reached a point where I just don't know what to look for anymore. When looking at the memory monitor it looks to me like in every loop iteration he accumulated about 100 MB of data, procceses it and throws it away, but not entirely. A small piece stays in the memory every time and in the end it clutters up all the heap space. What I already did: - Adding var to local variables - Replacing literals in queries with cfqueryparams - Replacing StructNew() at the beginning of loops with StructClear() - Replacing query-loops with index-loops I also started looking at dumps of the Java heap shortly before the process crashes, but I'm not really getting any wiser from that. I see that there are millions of objects in the memory and many of them are LoopTags and QueryTags, but other than that I have no idea what to make of it. I've read that placing the code of the loop within its own thread might help, but that's impossible because our task already runs in its own thread and apparently CF can't spawn threads from within threads. If you have any ideas for me where to look for memory leaks, what else to try or an explanation for what might cause the problem, I would be really really thankful!

Re: Extending a Component vs. Passing an Object
As usual, Matt Quack is spot on. I just wanted to add that extending is an IS-A relationship. If your service extended a DAO, you would say your service is a DAO. That's why Matt said they are very different objects. Is your service an object that talks directly to a database? No, it probably should not be. Going the other direction is also wrong, by saying your DAO is a Service. Is your DAO an object that takes in requests from your controller or other areas of your application that are making requests on your model? Probably not. Instead, injecting components, as you are doing, is called composition. This is a HAS-A relationship. Should your service have a DAO? Yes, probably. Now, if you wanted to remove all the plumbing of initializing and injecting your DAO into your Service, you can use a bean factory like ColdSpring or DI/1. nathan strutz [www.dopefly.com] [hi.im/nathanstrutz] On Tue, Jan 29, 2013 at 7:42 AM, Matt Quackenbush quackfu...@gmail.comwrote: A service object is a service object and a DAO is a DAO.

You will really need to confirm if you do actually have a caching issue. If you're using Firefox, use Firebug to watch your ajax traffic in the console view.

Re: Huge rowcounts in CFCLIENTS database
Yes, 90 days is the default, and it is absolutely excessive! How long do you really need that data to stick around? 30 days? I doubt it. I bet 7 days is plenty long enough, 1 or 2 days is enough for any normal application. Often, the database cleanup doesn't actually happen, so you have to do it yourself.

Re: Tracing Tool
How about lots of cftrace tags? cftrace gets no love. Or even something that abstracts your tracing, like a CFC that, depending on your logging level, will make cftraces, log to a file or a database, and ignore certain things based on severity. CFTrace is great. It lets you output to the debugging area if you have that turned on, or straight to the page, and it writes to a log file as well. And as soon as you turn off page debugging, the traces don't fire anymore, so it's safe for production. nathan strutz [www.dopefly.com] [hi.im/nathanstrutz] [about.me/nathanstrutz] On Sat, Oct 20, 2012 at 12:31 PM, Dakota Burns dakota.bu...@gmail.comwrote: Hi - I've taken over review of quite a large CF project built on CF8.

Re: cf-database vs cf-java-database
Yeah I wrote that in and then kind of coincidentally debunked it. Still, it feels true too often. With database connectivity, it's really not true. With object heavy development, performance still isn't there. If so, where are the benchmarks against php, python, Ruby, C#, JSP/JSF etc.? Obviously some of these platforms are much better than others in hard performance and in developer performance. Ruby for example is one extreme. Writing web servers and programming HTML with C++ is the other. I don't want to call you out, but I do want to see the facts. And finally, I will tell you I don't do CF because it's the fastest boat on the ocean or because it can haul the biggest loads. I do it because it's the nicest cruising vessel around.

Re: cf-database vs cf-java-database
Right, but what facts are you looking for explicitely? Like, CF can normally make N CFCs per second with M methods in them each. Yes. Have that on my desk by morning. Thanks. Just kidding, man, I don't write your checks. Unfortunately performance and applications is incredibly subjective, depending on hardware, applications and external connections including File I/O, network traffic, database calls, extra libraries and so on. On top of that, for testing cross-platform performance comparisons, you have to test something small that all application can do, so this usually comes down to math problems, which has very little to do with web apps (and lowest level languages always win). You have to test a larger app (like a pet market), but if you're just going for speed then you do a lot of caching, you remove extra objects and flatten object hierarchies, etc., it's not a fair test. Do I wish we could just see a true performance comparison in a fair and impartial manner? Yeah, but I know it's a pipe dream. Previous versions of CF have had a performance brief written up, e.g. the CF9 one: http://www.adobe.com/products/coldfusion/pdfs/cf9_performancebrief_ue.pdf Do you know if we will get one for CF10? I'm really interested to see how Tomcat helps under pressure. I know performance briefs are typically one-sided (I've been watching the jQuery blog for a long time now - yeah, i said it).

Re: cf-database vs cf-java-database
As with most things in ColdFusion, you get convenience over performance. If you use a raw database driver (and a front-end platform to handle it), you may have the option of streaming results directly out of the database and onto a web page. This is extremely performant and uses very little memory. This is not what ColdFusion does. CF pulls the results out of the database and drops them into a query object. This object looks more like a struct of arrays when you dig in (and it essentially is). Furthermore CF lets you manipulate the data, change the recordset, query off of it, merge it with another, and so on. It's crazy powerful, but not the fastest knife in the drawer. Adobe ColdFusion uses DataDirect (.com) JDBC drivers for most (if not all) of the databases. This makes it convenient for Adobe to farm out that hard work while providing a standard interface, but on the other hand, native JDBC drivers (i.e. drivers provided by Microsoft, Oracle and other database vendors) tend to be a bit quicker because they have a lot riding on their performance with Java applications. Those native drivers also usually contain more advanced, database-specific features. DataDirect, by their very nature, has to take a safer route. Then again, that's DataDirect's primary job, and you won't often find them more than a half-step behind and often two steps ahead, that's how they make money. Of course, you don't have to use the DataDirect drivers. ColdFusion will accept any valid JDBC driver (that's why the JDBC spec was invented). But then you still have the ColdFusion overhead. DataDirect + ColdFusion has the fantastic advantage of managing database connection pools, thread pools, network connections, network database resolution, security, and so on. If you think you can do a better job by writing native Java, then you work at the wrong company. In other words, this is way, way more work than anyone should ever sign up for, except those people at DataDirect (or Microsoft, or Oracle), or the Adobe CF team office. This is the kind of low-level programming that business application developers need to avoid in order to stay productive. Now, if you have some people who are handy with JDBC and can write great Java, it could make sense to put some of your objects into Java, but chances are, this is a bunch of baloney also. If your only work in Java is some SQL-containing database objects (first off I'd like to point out that that's not actually OO), then you are creating more overhead than you think. Instead of a CF JDBC-connector object, you'll be creating a custom JDBC connector object; personally I'd rather rely on Adobe to get this right, either way it's probably about the same amount of actual objects on the heap. Yes calling java from CF is lightning quick, and getting results back will be sliightly faster, let me point out a few things about your new development lifestyle: 1. You now have another language to maintain 2. That other language needs to be compiled every time you make a change 3. Unless you are on a very recent version of CF, CF may need a restart every time you change the Java code 4. Your SQL is in that other language, so now it is harder to get to 5. Your SQL has to fit into Java strings, so no more pretty line breaking and easy reading of SQL for the developers 6. There is nothing invented by all of mankind that is simpler than the cfquery tag 7. You now require CF and Java developers to do what used to take just a CF developer 8. You lose the ability to do query of queries and other CF manipulations So let's go back to the drawing board. First, are you sure you need to scale up? Could you scale out instead? Is it possible that a SQL database isn't even what you need? When you talk about scalability, maybe going to NoSQL databases would be a better fit. How about a cloud-hosted database where this conversation wouldn't even exist? Going back to the CF speed problem, I know a guy, maybe you know Mike Brunt too, he calls himself the cf whisperer, and it's true, he can listen to your app and tune your JVM so that it works faster than almost any pure Java app. If you're experiencing performance problems, almost every single time you'll find that you have a poorly tuned database, you're selecting too much data at a time, you're using inefficient joins, you don't use cfqueryparams, or something similar along these lines. There is a certain point, depending on hardware and the application, where you actually do have a scalability problem, but from my experience, some proper tuning and refactoring will get you way further than you think (until you have to spend $millions on real server hardware). ColdFusion server and its database connections are never the problem in my experience. Jumping to Java would be a bad call. nathan strutz [www.dopefly.com] [hi.im/nathanstrutz] [about.me/nathanstrutz] On Fri, Jul 13, 2012 at 9:57 PM, PT cft...@gmail.com wrote: Is there any advantage to having a CFC hand

Re: Best practices
Matt's dead on. It really doesn't matter very much, anymore. It's a style preference. That said, I would add that style is very important! The ability to scan a file and know what it's doing without guessing is an important thing. Having templates that match and create a cohesive feeling application is also important. With that, I'd say wrapping entire templates is ok so long as you don't force a lot of double-## escaping characters, because that looks ugly. Try to keep CFML out of your javascript except where it's necessary, because that looks ugly.

Re: CF10 Tomcat case sensitivity
I looked it up a few weeks ago, and, in short, that's not really possible. Tomcat 5 and 6 allowed it, but with the caveat that it breaks a lot of things and can exposes source code on Windows. Tomcat 7 deprecated the feature altogether. Sorry I wish it weren't true, but it is. I ran into it when trying to visit /cfide/administrator/, which is a 404 on CF10 because it's supposed to be /CFIDE/administrator/.

Re: best practice on session variable persistence and ssl?
I'm going to guess that you're dropping sessions because your HTTP cookies aren't secure, and your HTTPS cookies are, issuing a new identity to the browser every time it switches back forth. Putting your entire site in SSL mode is not a bad way to go, a lot of sites are doing that these days, but I understand not wanting to go that way if you can help it. From the way you described it, it seems like the easy way may be to give your less-secure application side its own application name and cookie domain and path, then when you go secure, you get a new cfapplication name, and new cookies for the domain and path. If they hit the insecure site it wouldn't matter because the cookies can't collide. That may or may not work depending on how the application is laid out. Still though, I think I've done things like this and I don't remember having this problem. It was a lot of years ago though. You know, back when security was job #2 (or 3...)! Actually I wonder if somewhere in your code you are issuing new cookies on HTTPS that are secure, and those wouldn't be readable from plain HTTP. It's a possible security hole (http interception, man-in-the-middle - not likely but possible) to keep your cookies insecure, but it would probably fix it. If you insist on keeping it all tight together, you might be able to pass your HTTPS sessionid over a URL link to the insecure site after the user is authenticated. That way they should have the same exact session. Again, you're passing HTTPS cookies over HTTP, so consider if this risk is ok for you. nathan strutz [www.dopefly.com] [hi.im/nathanstrutz] [about.me/nathanstrutz] On Tue, May 15, 2012 at 11:43 AM, Nick Gleason n.glea...@citysoft.comwrote: Hi folks, With our CMS / CRM application, we are looking at moving from a reliance on client variables towards more reliance on session variables, including as it relates to logins. One challenging scenario happens when a client is using SSL for ecommerce transactions. If a user logs in, using session variables for persistence, then goes to a page that is not in https and then goes to a page (e.g. an ecommerce screen) that uses https, sessions are dumped when the site goes into https and the login can be lost. We are probably going to solve that problem by just requiring the whole site to go into https. However, I wanted to know if there are other good ways to solve this. We have solved that kind of problem in a related scenario (with attribute scoped variables that need to survive https) by using wddx to store variables in the client scope and then get them back from there after moving into https. That has worked pretty well, but feels a bit complex. As we look at expanding our use of sessions, it seems like a good time to look at other options. So, are there other or better ways to keep session variables alive when a logged in user goes to an https encrypted page?

Re: after a long hiatus back to talk about frameworks
I was going to ask, which frameworks are the most popular in terms of actual employment statistics but even then, it might all be a waste of time if my next contract doesn't use ( framework x,y, or z ). Maybe what you are looking for isn't going to be solved by a framework, but by a better methodology. By far, the most popular way to write web applications these days, an improvement over the old Fusebox days, and certainly enabled (and sometimes forced) by all the frameworks, is MVC. The Model-View-Controller pattern is pretty ideal for web applications, and is one of the best tools we developers have these days. You can do it without a framework, it's not hard ( www.dopefly.com/techblog/entry.cfm?entry=307 and www.dopefly.com/techblog/entry.cfm?entry=308), and it's much more important than marrying yourself to any specific framework. nathan strutz [www.dopefly.com] [hi.im/nathanstrutz] [about.me/nathanstrutz] On Wed, May 9, 2012 at 9:20 AM, Don danfar...@hotmail.com wrote: But my approach to frameworks has been to 'wait and see'.

Re: after a long hiatus back to talk about frameworks
I'm not afraid to poke the stormcloud :) Fusebox went unsupported for a number of years and there was some drama about who owned the source code (it predates modern open source licenses). There was a failed fork and then the community stepped in and created a barrage of better frameworks. Recently, Fusebox has been open-sourced (on github) and there is a small team of people working on the next version. It may be too little and too late, but still probably a worthy effort. Even still, I would not recommend going that way. Many people believe Framework/1 (fw1.riaforge.org) is the true successor to Fusebox. It implements a couple features the same way, and it was created by the FB 5 and 5.5 primary developer Sean Corfield. Depending on the size of what you plan to build, you may be able to shrink your selection. The more enterprise options are probably Mach-II, Model-Glue and ColdBox. They do a lot and have a lot going for them. ColdBox is the younger of the three, and probably best documented, Louis also does great training classes. Model-Glue hasn't seen a lot of action lately. Model-Glue and Mach-II are heavily XML based and (to me) can get overwhelming. The more casual options are probably cfwheels and FW/1, but like John Bliss said, go with whichever works with your way of thinking.

Re: Cluster not sending request to second server
How do you know for sure that requests are not going to the other two instances on the second server? Remember, if you are using ColdFusion's clustering, your web server (IIS) on the second server will not get any traffic - Java clustering goes between JVMs and foregoes the all the web servers. Your web traffic comes in via one web server, passes to Java, then the cluster manager decides which ColdFusion instance to run the request on. You would have better luck checking for traffic based on the CF server manager or memory usage on the other server. Of course, I suppose it's possible the other clustered instances really aren't getting any traffic. Remove them and re-add them, or reboot the 2nd server. Maybe even the first for that matter. nathan strutz [www.dopefly.com] [hi.im/nathanstrutz] [about.me/nathanstrutz] On Mon, Mar 12, 2012 at 7:49 AM, brad f b...@ciswired.com wrote: I have two Windows 2008 R2 boxes, one running 4 CF instances and the other running two.

Re: How CF works
Larry, ColdFusion will not return something different to different browsers unless you explicitly tell it to do so. The most likely culprit here is bad HTML, Javascript and CSS. It sounds like an unclosed (or unopened) table tag, a missing quote on an inline style attribute, or something related. Set a doctype (I like !doctype html) and and run the W3C validator or an html lint, then try jslint and csslint, you will find the problem with one of these, and if not, just rewrite the html, remove your table tags except where they are literally needed, separate your styles and javascript from your html, and just spruce things up. If there's something about the page that IE doesn't like (and it wouldn't be the first time), move elements around and play with the stylesheet until it does. nathan strutz [www.dopefly.com] [hi.im/nathanstrutz] [about.me/nathanstrutz] On Thu, Oct 13, 2011 at 7:57 PM, Stephens, Larry V steph...@indiana.eduwrote: I have a page that does a moderately involved query: it returns 16 fields with 3 left joins, a simple WHERE and ORDER.

Re: ColdFusion 9 Session Replication
So the spirit of your question seems to be can you replicate sessions without software load balancing? The basic answer is that you can't. Session replication is a function of the CF load balancing features. However, there are other ways to read your question. If you are asking if you can swap sessions around without allowing your coldfusion servers to have software-based failover, I am not completely sure about that. It seems like something that should be possible, but I can't think of how, it's been a couple versions and a few years since I've managed clustered servers. Do you really want to disable software failover, though? It will be more intelligent than your hardware failover. Finally, I want to point out that session replication is typically a bad idea. It will eat up your network bandwidth and feast on your CPUs. It will have all your available memory for dessert. If one of your servers crashes because it is out of RAM, the other one will do the same. So how do you get around it? Obviously sticky sessions on your HWLB is the first step. But assuming your servers will crash, how do your replicate session data? There are lots of ways, and it depends on your application and what the application rules are for what data to store where. Sometimes session data can just be discarded and lost - things like saved search criteria. Sometimes you can rebuild it from data in your database - you just need a link from the session to the user information; you could use a cookie or put it in your database. You can also take advantage of CF's caching engine, Ehcache, which can do clustered cache, in memory, on disk, even state servers, and combinations of these all. Don't use client variables... just... don't. nathan strutz [www.dopefly.com] [hi.im/nathanstrutz] [about.me/nathanstrutz] On Sun, Oct 9, 2011 at 5:30 PM, Brad Parker bpar...@uhlig.com wrote: Here's a question hopefully someone can answer.

How do you compose your dev teams?
Hi everybody. I have a little management-type dilemma that I can't solve. I'm no manager, so I'm trying to collect info about how other people do it. I work in a small group of CF developers (7 of us) inside a big company (100k+ of us). The way we work is that pretty much everybody owns one or more applications in our group's portfolio of programs (probably 10 apps, 3 or 4 are big important). My manager has noticed that we don't communicate enough and has started threatening drastic measures, moving people around and putting us where we don't want to be. I am not sure of his motivation, but it may be partially the hit-by-a-bus protection, wondering if his apps will be supported if one of us eats a piece of public transportation.

Re: How do you compose your dev teams?
Great feedback so far, everyone. Thanks, keep it up. Will. The communication point is the only one I perceive. It has to do with lack of active developer knowledge on various systems, so dev-to-dev communication - I have my system and no one else really knows it, certainly not like I do. It's expected to a degree, but for the hit-by-a-bus scenario. The communication point comes from the complexity of our software and our loss of ability to add features fast enough. This is a technical debt situation, especially for some of these projects. Customers are getting agitated, developers are getting frustrated. My manager thinks we need to reorganize our group, so I'm looking for pointers to see how others do it. Projects are generally over-documented, CMMI style, so a lot of fluff and specifics, but not always something that says here's the system, here's how it works, you are up to speed in 15 minutes. It's like we have application silos, but we should be one single silo. I like the wiki idea. We had weekly status meetings, but it end up that no one cared what the status of the other projects was. I don't care if a project I don't touch is working on a feature I've never heard of (and i'm willing to take blame if I should).

You have that right? if not, then he's right to be concerned. Each project should be documented enough for a person with no clue about the project can come in and get started. This is never fun to do. It's something we are trying to do here at CF Webtools. We have an internal Wiki that we upgraded and are making an effort to document each clients site. With our developers spread around the country it's becoming important that we do this. If it's communicating the projects, status, progress etc, then maybe short meetings or status updates once a week are needed. IMHO some managers just need to quantify things. Provide the material he needs so he can do that and quantify you're jobs. If true cross training on these projects are needed, there are valuable tools to use. Besides documentation, tried pair programming. Take someone that has never worked on a project, put them at the keyboard and have the other person sit next to them and guide them along. Once each person has enough of the basics for each project, then maybe a project updates to the team to keep everyone informed will help. Or hey, try project swapping.

Roger, Spot on - all of us are completely remote. Some from our various sites around the country, some from our homes centered around the Phoenix area.

Re: How do you compose your dev teams?
Tariq, Very thoughtful response. I appreciate it! We haven't fully embraced Agile in our group. Mostly for the fact that it's a pain nobody wants to suffer, so we find ways to get around it. I guess that's where the scrum master role comes in. I don't know that we have anyone that forceful on the team. We probably have some who are forceful against it though. I like the idea of syncing up sprints between projects, so we all have the same release schedule - that would make it feel more like we are working at the same pace, same schedule and together. What did you have to do to make your team take the agile pill? Did you (or do you still) have any holdouts? nathan strutz [www.dopefly.com] [hi.im/nathanstrutz] [about.me/nathanstrutz] On Fri, Sep 2, 2011 at 3:24 PM, Tariq Ahmed ta...@dopejam.com wrote: So my question to the list is this: How do you organize your teams of developers successfully? Please let me know what you do, or what you have seen that actually works. Hi Nathan. I manage a team of 11 technical folks, and when I was promoted to management we had a similar challenge. Internal teams that build apps that support the business tend to get into this silo'd structure because what they're building has a specialized purpose, and as the business demands more of these specialized applications, it usually starts off with just one guy building it... and then they become the lone expert. With a heavy demand for change, the low hanging fruit it to use the guy who knows the app vs. risking someone unfamiliar with it who'll have to go through the learning curve. Management wise, it is a motivator to give people ownership. But, it is also a huge risk to have SPOKs (Single Points of Knowledge). Sure you can have knowledge bases, Yammer.com, IMs, Wikis, etc... and it's good to do that, but that's just information. It's only until you have a deep understanding of the domain/context are you able to leverage that information as knowledge. One technique I used was to maintain is a Knowledge Matrix of all our applications/features, I map out who knows what and what their strength is, and how critical/complex that feature is in order to calculate risk. I can then prioritize by risk, and make sure that other developers are getting exposure to these areas. Another highly successful thing we did was switching to Agile/Scrum development practices. Although you guys on a Visio chart are one team, you're functioning as independent one man teams. A Scrum practice you can start tomorrow are daily standups - from 10am to 10:15am everyone stands up together and discusses what they did yesterday, what they're doing today, and if they're stuck on anything (in order to invite others to help). It's time limited, no additional conversation allowed - that can be done outside of that meeting, no sitting down and getting comfortable... the team needs to feel confident that it never ever goes beyond 15mins. It'll help promote some awareness of what everyone is doing and encourage some communication. But it won't be enough to solve the problem as no one will really know deeply what you're talking about unless they're very familiar with the application. So the next step would be to truly get the team functioning together cohesively by going full Agile. Everyone is working together on the same cycle, and although different applications, you're working together as if it were one project. Very short iterations of 2 to 4 weeks, requirements are broken down into small little pieces - the team picks who is working on what, but no one is limited to working on just their app. You can try to learn it yourself - but getting in an agile training organization like cPrime.com to give your company a 3 day onsite bootcamp on how the process works is the fastest way to make it happen. Hope that helps.

Re: Run a class file generated with CF outside of CF
Brook,
Great solution. Kind of complicated but totally doable.
I won't pretend to understand the complexity of the cfc you have, but all
that overhead to run one cfc seems extreme. I have a couple suggestions.
1- use native Ant to do it all. You can concat files and run jsmin or yui
compressor straight from ant. I was experimenting with this most of
yesterday with some pretty good success and can share it if you are
interested.
2- use scripting from within ant. You can include the Rhino js.jar scripting
engine, or groovy, or any number of JSR-223 compatible scripting languages
and get access to Ant's methods like making a fileset from within
javascript, as well as all the underlying java libraries. This works really
well because you can still use a cool programming language and keep it all
within Ant, no railo or cfml dependencies required.
Anyways, just some ideas, and like I said, I can share some of that with
you. I plan on talking about this stuff a little bit from my CF Unconference
talk at MAX this October, so if you're in the neighborhood...

Hey Nathan,
So what I was doing was this. I am working on a new web app written with
extJS. I have a CFC that I call that builds the client side app. It reads
all of the ux and util directories and generates a config file used by
jsBuilder to compress, combine and minify the JS used on the client side as
well as compress and move CSS and resources.
I am working towards getting a CI server setup and also need to ensure all
developers can run a build locally. That's where the problem arises. The
developers (JS developers) will not have CF installed on their local
machine
(or our pre-configured EC2 instance), and so I need to move the process of
generating the jsBuilder config and executing it out of CF and into
something that can run on any developers workstation - without a big
install
and setup.
Since its just 1 CFC, I thought I could just use the java classes. But of
course there are dependencies.
I found a wicked, super cool solution to this last night! I downloaded
Ralio
Express and was able to get it to execute my CFC with basically zero setup.
Ralio Express is freakin awesome! There's no installer, you just run
start.bat to start the server and stop.bat to stop it. So I've added it to
my SVN and written an ANT task that starts it up and then runs the CFC that
indexes all the directories, read in an XML config file and calls (via
cfexcecute) the CFC that handles the build.
My ANT task has these targets:
target name=startRalio description=Starting Ralio Server
depends=MakeDirectories

dir=tools/build/ralio/
fork=true
spawn=true

I don't know if you can export from YSlow, but I know it gives you a very complete view of why a page is slow. Another one that seems less complete (to me) is Google Page Speed, again, a plugin for firebug, and this one I know you can export. After digging a little, I noticed they both work for chrome and firefox.

Re: OO ColdFusion, somebody tell me if this is overkill
Sounds like it's not a terrible idea. The pattern you're looking toward moving to is called the Service Pattern. It puts an interface into your Model. It's a good strategy if you are trying to reduce complexity (like number of functions in a component), split out concerns (like public versus private), accommodate a changing architecture (like you're doing), and especially if you will expose any of your application through web services later. Be careful that you don't put all your business logic in the services you create, creating an anemic domain model problem. Also, I would say congrats to you for seeing a problem, realizing a viable solution, and only later finding out that it's an already-well-known pattern.

Re: OO ColdFusion, somebody tell me if this is overkill
Oh Dave, you're such a literalist and a pessimist. Since we're talking literals, having a component with nothing but private methods is usually wrong, they will likely change to package access. So there :p I disagree with what you said about reducing complexity. Reducing the number of methods in a component and reducing the number of lines in a file, does reduce the complexity of the file, which can be a serious problem in a lot of applications. If the file is getting unwieldy and excessively large, splitting out functionality (in a logical way) is always a good idea. However it does add another complexity of having more files. Realize that the reverse of this is a single-file-do-all-spaghetti-chaos application, but taken normalization to an extreme gives you hundreds of useless files. Your software will be always be complex. How you handle it always matters.

I think you're assuming facts not in evidence here. The OP didn't mention any potential reuse or services layer. And simply creating two classes from one doesn't reduce complexity, it just moves it around. Finally, it's extremely common for classes to contain both private and public methods - objects are supposed to manage themselves without exposing implementation details, and that's what private methods let us do. Simply separating private and public methods into two objects doesn't really solve any problem if you're simply going to extend the class with the private methods in one new class. Finally, there's no mention of accommodating a changing architecture in the OP's question. I'm not trying to be unpleasant here, but I just don't see any of those concerns in the original question.

Re: application.cfm
First, I will say that this is a strange request, and chances are, you're doing something wrong. Compile errors mean that there was more than an error, it's that the template has serious problems that the CFML compiler couldn't parse. The fact that you still want one page to execute and another to not compile is weird, strange, odd. I can't think of a logical case for this, and would love to hear it if you have one. That said, you should be able to do this with an Application.cfc file instead of Application.cfm. Make an onRequest method, which will compile and run that function, then from there you cfinclude the requested template, which should be compiled only when execution reaches that include.

I love how this thread is comparing HomeSite to punch cards and other old fashioned computing technologies. In one sense, it's amazing that HomeSite had the staying power that it did. Kudos to the original Delphi developers for creating such a great platform. The only problem is that they did it in the 1990's. 15 years in computing, 15 years on the internet, we're talking about ancient history. I switched to Eclipse early on. I found myself at a company that had questionable licensing ethics, so when I started to hear about Eclipse, I made the switch as soon as I could and haven't missed the annoyances of HS+ one bit. It turned out great for me, I could tell there was a lot of promise in the platform, so now (7 years later?) it seems like I picked a winner. These days I use a combination of CFEclipse and Notepad++, both FOSS. Notepad++ is a great pick-up-and-edit tool. At home I have been using CF Builder 2, it's good. It's really good. I also have IntelliJ IDEA, which is surprisingly advanced for CFML development. In summary, and bringing it back to the thread, try new tools, they are better. They do more things. Force yourself to try it for a couple weeks and see if you can be as efficient at it. nathan strutz [www.dopefly.com] [hi.im/nathanstrutz] [about.me/nathanstrutz] On Sat, Jun 11, 2011 at 12:49 PM, Wil Genovese jugg...@trunkful.com wrote: Sticks of RAM?

Re: CFC argument best practice question
If you have a lot of arguments, one way to refactor that is to make a component that encompasses those arguments - essentially a bean, maybe a couple of beans if the arguments are unrelated. In your first public method, instantiate that bean with the arguments, then just pass that bean around. Follow that, and you've gone from just using components to actual object-oriented programming. nathan strutz [http://www.dopefly.com/] [http://hi.im/nathanstrutz] On Mon, Mar 7, 2011 at 10:06 AM, Brook Davies cft...@logiforms.com wrote: Hello, Just a quick Best Practices question.

Re: Downloading database tables
This one comes up from time to time. The best way to do it is with you chosen database's own development and management tools. If you use MS SQL Server Management Studio, they have integrated tools to copy a database. If you use Toad, they have something too. I have always had... let's say limited luck with those, but if you can get by with that, you should Now, if you wanted to do this in CF, it probably means work. I actually have a semi-functioning model of downloading one database and applying it to another, even works across database engines (e.g. download from oracle and apply to derby). Plus it takes snapshots so you can save versions of the database, including basic schema snapshots that you can import into another database, too. Then I got distracted, lost interest and have a 75% finished program. I'd open source it, but like I said it's not fully functional (not even fully baked), and I don't know that there's a real market for it.

That's a great tip, Steve. I've heard it before from the old CFEclipse days and practice it regularly. It works especially well if the projects you close are remote.

why is cf_builder so slow? (was: expensive)
Gerald, Your comments about CFB being slow bother me, and warrant some exploration. Can you provide more detail? Do you have projects set up into a shared dev environment over the network? I can't imagine that would be fast for any IDE. I have a copy of all my projects locally, I install CF servers locally (4 different server versions), and I update my dev test servers only by exporting from source control. Having these projects locally lets me do development without screwing with other developers' dev environments. I can't tell you how many times I was refactoring an application's guts at the same time a co-worker was working on a new feature (sorry Alan!).

Re: why is cf_builder so expensive?
Wow that's kind of a loaded question, and potential flame bait. CFB is expensive because it's in line with other products from Adobe. They don't make cheap software, they don't make bad software. They do a good job and they support it really well. CFEclipse was created on free time and borrowed time and, even once in a while, bought time. On the other hand, Adobe pays people to create their software, they don't get it or make it for free. I would also add that CF Builder is important in the marketplace because it solidifies CF as a fully supported platform, end to end. Many people purchasing software want to buy from one vendor because they know homogeny always works. Not offering CFB means Adobe loses money. CFBuilder is not actually all that expensive considering what you get with it, and compared to a lot of other professional development tools. IntelliJ Idea is $700. Visual Studio's pricing structure needs a full map, but the pro version is around $800. Unfortunately for all of these companies, there are great open source alternatives. Personally, I use CFEclipse, but that's just because I'm waiting for my company to come through with the CFBuilder licenses. Though I would probably keep CFE on hand for those special times. Also, I have Notepad++ (with CF plugin) as a quick pick-up editor for one-off things. nathan strutz [http://www.dopefly.com/] [http://hi.im/nathanstrutz] On Tue, Jan 25, 2011 at 7:00 PM, Michael Firth mfsqlser...@gmail.comwrote: Thoughts about cf builder.

Re: relative path for images
You have to remember your context. Your CF application's context is on the server side, and usually includes are relative to the page you are including from. Images are included from the client side - the browser, so they are relative to the URL of the current page. Often, it helps to include your images in a web-root-relative path, so your src would always start with a slash. /images/photo.jpg instead of the relative locations images/photo.jpg or ../images/photo.jpg - this way, it doesn't matter where your page is, as long as it's on the same site.

Re: Issues with session variables
For the timeout issue, there are a couple things, but most likely, your CF5 server is crashing. This is especially true if you have a busy server or use session application variables a good amount without using cflock. I think (and it's been a LONG time) you can check to see if your server is actually restarting itself by finding your windows event log. This is very possibly the case especially if you are experiencing this on your production server but not your development server (assuming you have one and they are separate machines). The solution? Upgrade your server to CF9 or if it's a money thing, go to Railo, it's perfectly fine and will do the job as well as give you a million new features that you can start to use. CF5 is well over a decade old. Stop running it. Stop punishing yourself. You are worth more than this. Oh I just noticed you said it works with client variables, too. Check the client timeout, check your cookie timeout, especially with Firebug to make sure they aren't set to expire within a minute. Then look for anything that interacts with cookies, cfide cftoken. You can pass #session.urltoken# in all your links to eliminate any possibilities of having a cookie issue. nathan strutz [http://www.dopefly.com/] [http://hi.im/nathanstrutz] On Thu, Jan 13, 2011 at 11:26 AM, Maneesha Aggarwal ma...@columbia.eduwrote: We have an issue with early timeout using session and client variables.

Re: More rewrite rule fun
Will, that's right. The \w switch is roughly equivalent to [A-Za-z0-9_], aka, letters, numbers and underscores. I put \w/ in there to capture the \w words and / forward slashes. This regex just captures any words slashes after /parts/, which is pretty good because it makes the ending slash optional. If you have other characters in your subcategories (like dashes), you can just add those to the [\w/] char group. You could get fancier, and capture the subcategories individually, but it gets trickier, and making that replacement in CF is so much easier. nathan strutz [http://www.dopefly.com/] [http://hi.im/nathanstrutz] On Wed, Dec 22, 2010 at 8:10 AM, Wil Genovese jugg...@trunkful.com wrote: The \w typically means match any word.

Re: CF9/Win7 64 bit issues
I'm not a pro in this field, but I know a few tricks. First, did you install the IIS 6 management console? If not, CF has trouble connecting to IIS7. I think you just have to have it installed, you can still manage via IIS7 tools. Second, you can always use the built-in web server. You can enable it through an XML file somewhere, but I find it's easier to reinstall CF and turn on the internal web server in the installer. Finally, my last trick is the wsconfig app, Web Services Configuration Tool in your start menu. You should be able to delete and recreate the connection to your web server. As for debugging, I wonder if your CF server thinks somehow it has a different context root other than just / - you could look for that and who knows, maybe you will find your /inetpub/wwwroot/*.cfm files answer to localhost/cfusion/*.cfm.

Re: Memory Usage Question
Brook, At first glance, I'd say you need a consultant like Charlie Arehart ( http://www.carehart.org/) to see why your application is performing like this. Usually, there is a way to fix the offending memory hole. If you think you can do it, hire Charlie for an hour or so and he will give you some pointers. If your staff doesn't have the talent he can probably fix it completely. There are some alternatives to that plan including hiring Adobe support, or find and hire another expert. Some names that come to mind with deep server experience are Mike Brunt Steven Erat. Ok, back to your problem. 1. Windows task manager reports used memory by default, not allocated memory. Turn on the Virtual Memory Size column in task manager and you should see the full amount. 2. I don't really know about SeeFusion and what it reports on. Maybe ask them about it? 3. It sounds like the request is still running even though the browser request has ended. I think overall what you need to do is fix the offending code. You have a memory leak. It's not ColdFusion, it's not the server, it's your CFML. I would guess that the client storage / array looping operation is a pretty hairy one. Move your client storage into actual database tables and columns and turn off client variables. Think about how you may be able to pre or post-process some of the long-running operations. Run them on a different server. If you have a lot of database operations, cut them down. If you have a lot of components, cut them down. Oh, and good luck. nathan strutz [http://www.dopefly.com/] [http://hi.im/nathanstrutz] On Fri, Dec 3, 2010 at 10:51 AM, Brook Davies br...@logiforms.com wrote: Hello, I have a question about a memory usage pattern that I am trying to figure out. I am using seefusion to watch our server and this is what I am seeing: 1. We have two webservers and a loadbalancer with equal distribution and sticky sessions enabled 2. Memory usage will be constant around 20%-30% in use throughout the day. 3. When I check the taskManager on the machine I see jrun using only 300-400 megs. 4. The arguments to the JVM are -Xms1024m -Xmx1024m -XX:MaxPermSize=384m -XX:+UseParallelGC 5. The app uses client variable storage with a MSSQL database backend 6. The client variable data per client (in some edge cases) can grow to be very large What I am seeing is a specific customer comes along and uses our app and they have some very large strings of data stored in the client scope and invoke some operations that do a lot of array processing on large arrays. These requests are big and slow. We see a big spike in the memory usage. It continues to grow and grow. Then the client appears to disconnect and leave the website (in fact, we verified by banning their IP to test). But the memory never gets released. The task manager now reports jrun up at over 1 gig of memory. We have a script that runs every 30 seconds that checks memory usage and does a full GC when less than 100 megs of memory remain. Prior to implementing that script, we were seeing some out of memory errors. While watching seefusion we can see the memory creep up to 90%+, and then to 10% when the GC script runs. But it immediately begins to climb again. And this process repeats. The traffic on this server is no different than our other server which sits at 19% memory usage. Now, if we restart CF, the problem goes away, and memory usage stays at under 20%. My questions are: 1. I understand that setting -Xms1024m -Xmx1024m should immediately allocate that amount of ram to the JVM. So why does the taskManager report the memory usage at 300 megs (prior to the event)? 2. If a bunch of requests cause memory usage to spike and then those requests die off, should seefusion show memory usage at 90% because thats whats allocated to the JVM and now 'claimed'? So would that be a normal operating condition? 3. What would cause the memory to immediately climb back up after a full GC after 'something' happened but not climb after the service is restarted? Thanks for your insights guys!

Re: Dumping VAR Scope?
Rick,
Short answer: You can't.
Long answer: This was a design flaw that was corrected in ColdFusion 9. In
CF9, you can dump #local#, which is the function local var scope. Earlier
than that, you best option is to create a struct for your function-local
variables, so many people do this:
[pseudocode, writeDump and abort are CF9 specific]
function foo(arg, etc) {
local = structNew();
local.myLocalVariable = 1234;
writeDump(local);abort;
}
Hope that helps.

Re: How to display LARGE amounts of Data in a Timely Fashion
Your problem is probably render time, which makes sense if you have a ton of data coming out in a table layout. What you can do is remove as many of the tables as possible, especially for any layout stuff, headers, footers and the like. If you wrap the entire contents of the page in a table, your page has to finish downloading and then figure out how to render, which takes time. You can streamline this process by using CSS to lay your page out. Another thing, and probably the best increase, is if you use a fixed table layout (table-layout:fixed; in CSS). That will render your table with the same dimensions as your first table row, thus forcing the rest of the rows to fall in line. With that set, the browser doesn't have to download the whole table to start rendering it, it renders as it downloads. Another trick that I see around lately is the automatic scroll loading (don't know the official term). The idea is that once someone reaches the bottom of a page of data, more data loads, so you never really reach the bottom until the data has all been loaded. Google Reader was one of the first big sites to do this, but now it's more common. With this trick, you only need to load a couple pagefuls of data at a time. Consider that last one, sure, but DO those first two, for real. nathan strutz [Blog and Family @ http://www.dopefly.com/] [AZCFUG Manager @ http://www.azcfug.org/] [Twitter @nathanstrutz] On Wed, Oct 21, 2009 at 8:22 PM, Rick Colman rcol...@cox.net wrote: I need to query, retrieve and display a large amount of data; i.e. 4100 rows by 50 columns of numerics, to the browser screen.

Re: CFC's.. Why use them?
Brad, I love the microwave analogy. Phillip, CFCs as a fancy include tends to be the first step on your way to really understanding components and objects. I've been with a few groups who have gone (and taken me) through the course. The evolution is like this: --- CFC as a function utility library. Functions are a small piece of reusable code, putting them together makes sense. Put that util.cfc in the application scope, seems to make it faster. (now it's a singleton) CFC as a place to put your queries. Moves them out of separate files or the top of your cfm pages. Some get stuck here because this is the least reusable stage. This is not OO and makes working with CFCs very uncomfortable. CFC as the action back-end (the model) to an area of your application. Similar to the above, but may have more processing, and some functions without any queries. CFC as a black-box to a specific concept in your application. Finally a real object with properties and methods. Now, finally, you have an object that can be reused. This step usually comes out of need for something that has to be used in multiple apps or laziness (in a good way), not wanting to re-type boilerplate stuff like a user/login system. And finally, eventually, an actual model, with more objects and some actual layers of objects. Here, you will recognize larger pieces of your application that can be reused, not just single CFCs. --- This is not to say that everybody will do this, everyone's experiences are different, but it's just a pattern I've seen. nathan strutz [Blog and Family @ http://www.dopefly.com/] [AZCFUG Manager @ http://www.azcfug.org/] [Twitter @nathanstrutz] On Tue, Sep 8, 2009 at 10:47 AM, b...@bradwood.com wrote: I'd sure hate to write a SOAP webservice in a .cfm file.

Re: CFC's.. Why use them?
Peter, I understand the singleton pattern. It's lovely, on a cloudy day or sipping some tea or whatever, but in CF, don't you think that implementing the true singleton pattern is overkill and generally unnecessary? Consider our lack of true constructors, the stateless nature of the web, and multiple server configurations that many of us use. Honestly, I'm just interested in your opinion. Or, are you just saying we throw the word around like candy at a parade and should stop before we hit someone in the eye?

A CFC in the Application scope is an instance of that object, but there is nothing stopping you creating multiple instances of that CFC - whether still in the Application scope or other scopes. A Singleton is an object that *can only have one instance*, returning that same instance even if you try to create a new instance. And, particularly with OO, the times when you actually want an enforced single instance are rare - so if someone starts talking about Singletons, there's a good chance they've misunderstand OO's concepts. ~| Want to reach the ColdFusion community with something they want?

Re: Question re: Reactor
Caroline, There haven't been very many big changes in Reactor for a few years. You should update to the latest version and see what breaks. (but no, I can't confirm that it works or doesn't in SQL2005) You may be able to win if you just update reactor, (making sure to delete the cache files in the reactor directory) and refreshing your app... nathan strutz [Blog and Family @ http://www.dopefly.com/] [AZCFUG Manager @ http://www.azcfug.org/] [Twitter @nathanstrutz] On Mon, Jul 27, 2009 at 4:47 PM, Caroline Wise caracol...@gmail.com wrote: We have a rather old application that uses an early version of Reactor (vintage 2006-ish). It works fine with SQL 2000 in the development environment. We don't get many change requests for this app so while it gets a lot of use in the production environment, things on dev and staging are pretty quiet. Recently I had to make an extremely minor content update and it turned out that the staging box version had an issue inserting a new user, a problem we could not duplicate in development or production. When I compared the the Reactor code it turned out that it was different for this part of the application. The user table is using some defaults and they were not picked up in the Reactor code. The client, who has control over the staging environment, updated the database to SQL 2005 some time ago and my suspicion is that our version of Reactor can't cope. I'm wondering if anyone out there is using a newer version of Reactor and can confirm that it works fine with SQL 2005. Also of course I'm trying to gauge the risk and effort involved with updating Reactor to that newer version. Would I have to replace the whole thing or are we talking about something akin to a plugin for 2005?

Re: Function Encapsulation Gone Too Far? - Opinions
It's hard to say if you're really overdoing it. In one sense, the component is pretty well encapsulated. Accessing the cgi scope just in the constructor is fair enough, though for the true purists, you could move that out, and for the OO realists, you could just put cgi references anywhere. Also the use of the constructor, while not a no-no, is usually overlooked in support of an init method. I know I always look first for an init method well before looking for constructor code. Still, it's perfectly fine. If you think this is an area of your app that will change, then by all means, encapsulate it, give it its own object etc. However... It's like 3 lines of code you could drop in your onRequestStart method. You'd eliminate an entire object creation, 2 cffunctions, 20+ lines of code: cfif cgi.server_name neq listFirst(arguments.hostName, .) . evansville.edu or cgi.https neq on cflocation https://; listFirst(arguments.hostName, .) . evansville.edu/ / /cfif But if you are going to need to overwrite that functionality in certain cases or add complexity later on, you might as well separate it out at least a little. nathan strutz [Blog and Family @ http://www.dopefly.com/] [AZCFUG Manager @ http://www.azcfug.org/] [Twitter @nathanstrutz] On Tue, Jul 21, 2009 at 12:01 PM, Dawson, Michael m...@evansville.eduwrote: The code below contains a couple functions that determine if HTTPS is on and if the server_name is the same as the full domain name.

Re: Function Encapsulation Gone Too Far? - Opinions
Mike, I can get behind one method that determines if it needs redirection and another that does the redirecting. Actually, because it's simply 1 if statement, I don't oppose putting it all together in the same method. Think about this procedure changing in the future. Again, that's what it all comes down to. If you are going to change the if-check to see if it needs redirection, you're very likely to change the location you redirect to - IMO, they are related too closely to separate. Also remember that less is less. Fewer methods means less complication, fewer lines to maintain, faster code navigation, faster developer ramp-up speed.

Re: AJAX
Yes, the frameworks are different, but really, there is only a few that matter, and only one of those that really actually matter. jQuery is, by far, the best. If you pay attention to most javascript questions people have these days, it's something like this: Q: How do I do X in javascript? A: You don't. Just use jQuery. If you want a whole widget ui framework, use ExtJs. Otherwise, just use jQuery. It's unbelievably good. jquery.com has a tutorial area http://docs.jquery.com/Tutorials which is good.

Re: pagination and large recordsets (mysql)
Mike, The idea is pretty good - in fact, the mysql function found_rows() is very intriguing. Now, with the code example, I would say that is really, really bad SQL, putting the entire where clause in the URL - you're right to be suspicious. I am sure you could just rig up the query to use queryparams and it would be fine. Now, having said that, I also think reinventing pagination isn't useful at this point. I have this project at riaforge - http://paginationcfc.riaforge.org/ - a well documented CFC that handles pagination. The problem between my component and using mysql like Jules, is my component uses the recordcount of the query to determine how many pages there are. You can, however, extend it to do just that. Check the docs under extending to see an example: http://www.dopefly.com/projects/pagination/pagination_cfc_documentation.cfm#Section6 It looks like, to do it, you will probably have to make setTotalNumberOfItems() a public method, then also override the private method configureInputs.

Re: Old CF project (1000 .cfm and .cfc), refactor into framework
Isaac's got some great stuff in there. I just wanted to throw in a couple things and reword what he said my own way... Typically, a non-frameworked app with thousands of cfm and cfc files is either made very well, or it's coded like spaghetti with meatballs. If it's well constructed*, why move to a framework at all? If you are really into it, you may fare pretty well with a framework that does a lot more convention over configuration. Fusebox 5.5 (without xml), CFWheels and I think the new Model Glue beta can pick up a lot of your files without you having to configure them all. * My idea of well constructed means it's MVC where the model is a nice and complete thing, portable between frameworks or different front-ends - not necessarily the 4 objects per database table and certainly not all our queries in this cfc, util functions in this one. Also, bonus points if you have unit tests, more if they pass. Read up on Hal Helms' stuff if you need hints on how to get to this point, he has a lot of thought provoking what should the model be, really? kind of stuff. If your app has a lot of includes, especially if nested (it's spaghetti code), and meatballed objects thrown in for whatever random thing, and especially if you have more than 1 cfc call per cfm, then you could be in trouble. Depending on how bad it is, you are looking at months of work and a partial rewrite. Of cours then if your HTML stinks too, and you have a lot of inline styles and use tables for design, you may want to re-do that as well, so, that's essentially a full rewrite. Now, to choose a framework or not. It sounds like you're doing some high-level rethinking of your app. If you decide to go non-framework, won't you just end up in this same spot again in 2 years? Do something that will last. Do something that's structured the most obvious way for new people and for yourself in the coming years. If nothing else, get your entire model into well encapsulated CFCs and your app into a generic MVC structure, then you can port it pretty freely to any MVC compatible framework. Trust me, you will thank yourself repetedly every time you need to update it, and programmers down the line will bless you instead of curse you. nathan strutz [Blog and Family @ http://www.dopefly.com/] [AZCFUG Manager @ http://www.azcfug.org/] [Twitter @nathanstrutz] On Wed, May 27, 2009 at 9:17 AM, s. isaac dealey i...@turnkey.to wrote: I want your opinion ( or experience ) with refactoring an old project into a framework. I am working now on a old non-frameworked project with plain cfm files with .cfc function and object libraries. This projects contains a bunch of .cfm files and .cfc. About 1000 items. The discussion with my colleagues is that some want to refactor the whole project in a framework. I think it's to much work, and you can better start from scratch. My other colleagues disagrees. Do you have any experience or opinions? Both approaches work. There are a lot of variables involved, so it would be difficult to offer a blanket suggestion about how to approach this problem. The amount of business logic that's been placed in or left out of the CFCs will have a dramatic impact on the amount of time it's likely to require to convert the application to a framework. If most of the business logic is already in the CFCs, then converting to the framework shouldn't take very long. If you've got a lot of business logic in .cfm files currently, you might want to start by converting that logic into objects -- which is what you want anyway, irrespective of which framework you choose. And at least for that portion of the migration project, I would tend to say that it makes more sense to keep the business logic you have rather than start over from scratch, since that has nothing to do with your framework. The rest of the project will be converting the views (HTML) and creating events in the framework's controllers. It's not difficult but it can be tedious. The onTap framework is designed in a particular way that allows you to convert individual pages incrementally in a time permitting fashion. None of the other frameworks I've seen will allow you to do this yet, you either convert them all at once, or not at all. The onTap framework will also allow you to maintain your existing links and form actions, which again, it's the only framework I've seen that will eliminate that step from your workload (though I've heard that upcoming versions of FuseBox will have features that allow this... I think). Incidentally, I converted Ray Camden's Galleon Forums application to 5 different frameworks - ColdBox, Mach-II, Model-Glue, 2 versions of FuseBox (with without XML) and the onTap framework. In total the project took me about 2 week. I don't think it had 1000 files, however, I was able to replicate the migration to 5 different frameworks all by myself during that time while still maintaining a 9-5 job. So I think that says
