Re: Moving part of my hosting business - thoughts about my plan please ...
Coming in a couple of months late here, but I've just been through a move from Windows/Adobe CF/MS SQL Server to Linux/Railo/MySQL and found a couple of things not previously mentioned. Windows - Linux: already covered above, but I'll just add that anything that turns into a file name (like CFC paths) is also included in the case-sensitivity issue. One issue that hit me was case inconsistency in strings stored in the database that were later used to build path names. AdobeCF - Railo: Even aside from the unsupported tags, syntax compatibility although very good is not 100%. See e.g. http://lagod.id.au/blog/?p=378. A lot of this will come down to coding style - your code might be completely fine. The big thing for me though is the way Apache and Tomcat work together. ACF goes to some lengths to disappear the Tomcat layer and make the whole thing look like a web server that miraculously knows what to do with cfm files. Railo is much more of a classic Tomcat app, in that it is definitely sitting behind the web server with its own separate configuration. I can go into more detail about the consequences of that if you like, but if you take the path of least resistance (use mod_cfml and make the Apache document root the same as the Tomcat context root) then at the very least you end up with a dirty big WEB-INF folder in your document root. MSSQL - MySQL: CRUD queries will almost certainly be fine. Heavy-weight slicing and dicing queries probably won't. There are lots of differences in DDL (I have a very home-brewed set of regexes that did the trick for me - happy to share). Stored procedures will need to be completely rewritten. Many functions are different, but most have direct equivalents. One gotcha is that when MySQL is running on Linux, database object names (e.g. table names) are case sensitive. That sounds like a lot, but it is perfectly feasible to have one codebase that will deploy and run happily in both environments (that might not be a requirement for you, but it does illustrate that the differences are not major). My total changeover time was about six weeks, but I was completely reworking my build and provisioning procedures at the same time. Feel free to ping me on or off list if you want any more detail on any of this.

You don't want to be debugging so many different issues at once on an OS you aren't intimately familiar with (and maybe not familiar at all). You mentioned you are on Win2003. Have you by chance missed out on running CF on a 64-bit Win OS? That was like manna from heaven when I first switched. Consider a Windows VPS from Viviotech. They can license you a copy of CF Enterprise *very* inexpensively. They are surprisingly robust for the prices charged, they are CF-literate and an excellent firm on general principles. From there consider leasing another Windows VPS and put Railo on it (Viviotech will do this for you for a small setup fee or for free IIRC). Then tinker away, migrate a low-profile site over when you're ready etc. This is what I did with my personal sites. You could take it a step further and after mastering Railo, retire the Windows/Railo VPS, fire up one with linux and start over again on the tinkering so you limit your issues to that part of the change. If you need more horsepower and have the budget for a CF license, look at the blade servers at Cybercon; check out their hardware configs. I don't see how you can beat those prices. My servers there have been absolutely reliable. -- --m@Robertson-- Janitor, The Robertson Team mysecretbase.com ~| Order the Adobe
Re: Can application scope gateways/DAOs returning an array of Objects?
Hi Jonathon,
There's only one thisContact variable, which is being reused each time
through the loop. So all you need to do is put:
cfset var thisContact =
right at the start. There's an indeterminate number of values that are
passing through that one variable on their way into the array, but it's
still one variable.
And of course var scope returnArray and q_Contacts as well. If you're on
CF9 things may a little different in that you may not need to explicitly var
scope, but I'll let the CF9 gurus pick that one up.

trouble understanding the need to VAR scope all internally used variables
when I've got a dynamic number of objects being returned. That's not very

cffunction name=getContacts access=public returntype=Contact[]
cfset returnArray = ArrayNew()
cfset q_Contacts =
cfquery name=q_Contacts

cfset ArrayAppend(returnArray, thisContact)
/cfloop
cfreturn returnArray

So, my concern is with the inability to create the Contact objects in the
VAR scope since I don't know how many I'll be creating before hand. If I do
it like this (i.e. without the VAR on the createObject), am I setting myself
up problems? If so, how should I handle this?
Thanks again, and I hope it's not to ridiculous a question.

Re: SQLServer Express and SQLServer - totally compatible?
Just a thought: if you're carting an external disk back and forth, why not put a VM with SQL Express and your databases on that disk? Personally I run a little VM farm with SQL and CF all off the one eSATA disk. All is kosher as far as SQL is concerned, and if you need to get data onto another server you've still got linked servers and/or SSRS, or even just a file copy of the results of your processing. BTW, I would not be at all suprised if SQL had some kind of fit when your database files arrive back from wherever with a big hole in their LSN's. It's precisely for this reason that detaching/reattaching is necessary.

I dont want to keep attaching and detatching lots of databases - i'd rather just connect the external database to this machine and then boot it up. So if i have SQLServer2005 (the full version) driving the databases when I'm working at one location, and SQLServer2005 Express driving the databases when I'm working at my other location, will that cause problems in the databases? Are the two versions fully compatible at least as far as database file structure etc is concerned? I should also add that I'm only going to be using the Express on a dev machine - not connected to the internet, and there wont be multiple users. And i hardly ever use the advanced features of the database for these little applications - things like syndication and triggers etc - i prefer to have ColdFusion take care of all those kinds of jobs. So for the most part, the databases are simple data storage mechanisms, with all the processing of data being done in ColdFusion.

Re: Possible thread issue?
Andre, Yeah, looks like singleton, but you'd have to find where the service is instantiated to be sure. Throw it back to the guys who wrote the code anyway! They should be var scoping always. Don't know about the classid. You can of course get the hashcode - see http://www.compoundtheory.com/?action=displayPostID=42. Failing that, a common but invasive way to establish CFC instance identity is to set a variable: cfset transDAO.__variable_name_unlikely_to_be_already_used = I'm back!!! and then next time around check IsDefined(transDAO, __variable_name_unlikely_to_be_already_used ).

Re: Possible thread issue?
Andrew, I can't help thinking the code you haven't shown is important. Are you creating a CF thread? And are any of your variables in shared scopes? Transactions and threads don't necessarily work the way you might expect. There are lots of possibilites for cross-talk between threads, connections and transaction in a CF thread scenario, particularly where shared scopes are involved.

RE: Java Training: moving from CF to Java
Answering for myself, not for Dan: 1. Java is a squillion times faster than CF (OK, it's only about 200 times faster - might as well be a squillion) 2. That means it becomes feasible to create a truly cohesive OO domain model, which can be a lifesaver for large apps. 3. And once you have that domain model in a jar file, it can go anywhere - desktop apps, backend datasource for an LDAP server, suck it into .NET, trad JEE server...

RE: Java Training: moving from CF to Java
I'd want to see some pretty solid benchmarks before I believed that the Java written by CF is 200 times slower than the Java written by a random programmer. The 200 times difference comes from my own comparison of the same domain model implemented idiomatically in both ColdFusion/ColdSpring/Transfer and Java/Spring/Hibernate. Similar experiments conducted by colleagues give similar results. Mark Drew did some testing with a totally different scenario, but the results are in the same ballpark. Not sure why you'd find this surprising. Java code to solve a given problem isn't remotely similar to the bytecode that CF spits out for the same problem, unless that problem happens to be interpreting a dynamic language.

RE: dynamic names for named locks
I do this frequently. Works well. Jaime -Original Message- From: Rick Root [mailto:rick.r...@webworksllc.com] Sent: Monday, 9 February 2009 9:51 AM To: cf-talk Subject: dynamic names for named locks Is it possible to use named locks with dynamic names? I've got a site running a single application under thousands of domains. Site information for each domain is stored in the application scope so I don't have to get it from the DB all the time. So my first lock looks like this cflock name=appInitLock1 type=exclusive timeout=30 cfif not structKeyExists(application,sites) or NOT isStruct(application.sites) or isDefined(url.reinit) or isDefined(url.init) cfset application.sites = structNew() /cfif /cfif My second piece that is locked is specifically to get or set the detail within the application.sites struct with the site specific information based on the domain name. So while many threads *MAY* execute the code, only threads making a request to the same domain would need to be protected from each other. So I was thinking about doing a named lock with a dynamic name based on the domain... ie: cflock name=appInitLock2_#replace(request.domain,.,,ALL)# type=exclusive timeout=30 Would this work and can anyone think of any reasons NOT to do this?

RE: sharing vars between applications
Jessica, I'm making some big assumptions here. Firstly, I'm presuming you don't want to go as far as having a real distributed authentication mechanism like CAS, Kerberos or Shibboleth, and that your servers aren't authenticating against a Windows AD. Secondly, I'm presuming there's no way to get both sites running on the same CF instance, as this is far and away the easiest way to share data between CF apps - just give the two apps the same application name and that's all. Given those assumptions, the low-rent way to do this is to pass the user's authentication details through to the secure site in a form post or in a cookie when the user navigates from one site to the other. For more security, have your member site notify the secure site via a backchannel (e.g. CFHTTP) when somebody logs in. Then the secure site can compare the details coming in from the browser with the notification it previously received from your server, and reject the request if there's no match or the request is stale. Just make sure the backchannel is properly restricted, preferably to a single IP address. For even better security, you can encrypt the backchannel as well. Note that in this scenario authentication details need not mean the actual data of interest - it may be a time-limited key that you can then use to look up the data, perhaps in a shared database or by issuing a webservice call. This is a very simplified version of what things like Kerberos and Shibboleth do, and if it's all you need it will probably take weeks less to do than setting up something like Shibboleth.

On the upside, you should find rich pickings in the list archives. Basically both of your proposed solutions sound fine. If there was a consensus (not sure if there was), I think it would go something like: 1. Your instinct to remove the reusable validation logic from the controller is sound. 2. Putting it in the service is OK 3. Breaking it out into a separate validation object is also OK, and maybe slightly preferable.

Well, it's kind of cool that cf-talk is having the TDD argument. Don't really mind how it turns out. Makes me feel good about being a CF programmer. @Bill, Thanks for the links. The thing that intrigues me about a lot of the TDD debate, including these articles you point to, is that most of the anti-TDD side of the argument ends up espousing pretty much all of the principles of TDD in the very act of trying to refute it. So a lot of the debate is actually about people reacting to what they see as extremism and overly prescriptive statements. IMHO, there's nothing wrong with strongly stating a principle - everyone knows that principles get modified in application - but it's true that some people get way too personal about it. The rest of the debate is along the lines of I blindly followed the letter of the TDD law while ignoring the principles and it didn't work for me - therefore TDD is flawed. The poster then lays out how they manage to apply all the principles of TDD in some other way that is superficially different from cookbook TDD. So leaving those two smokescreens aside, I have yet to see anyone even attempt to seriously contradict the principles of TDD - but I'm still looking!

You will actually rewrite less of your stuff than otherwise, because writing tests first really brings a poorly factored design into the spotlight much earlier than would otherwise happen. The assertion is that if you can't write a test you don't *have* a design, or indeed a clear intention. And if your tests are hard to write, it's because you have a bad design.

RE: HELP! SQL Injection Attack!
If you block APNIC's range you're blocking the whole of the Asia/Pacific region. APNIC is not an ISP or large company, it's actually the regional authority for internet addresses, so it owns *all* addresses in Asia/Pacific - just like ARIN owns all addresses in North America and RIPE owns all addresses in Europe. Your lookup is resolving back to APNIC because you're using your regional authority (in your case ARIN) and it will only resolve addresses in its own range. For all other addresses it will just refer you to the appropriate regional authority. If you then use *that* authority's whois, you'll get the real story. Oh, and if you try to automate this to look up lots of addresses, you're breaking the terms of use of the whois server. I'd imagine they'd block you, but I've never tried it.

RE: When is is time to upgrade to Enterprise Edition?
Have you tried making the perm size bigger again? With lots of apps,
especially if any of them are using frameworks, you'll be using the perm gen
pretty heavily. If your app is freezing with plenty of headroom left in the
heap, perm gen is certainly a suspect.

Hi Mark,
To clarify about the JRUN memory usage: I'm looking in the Task
Manager under the Processes tab. When I sort on the 'Mem Usage'
column, jrun.exe is almost always at the top of the list, with at
least 350 MB of memory being used at any time. I'm also running
FusionReactor to monitor memory usage, but that tool doesn't
include the permanent heap in it's stats. I read some postings
that suggested looking in the task manager, since that *does*
include JVM memory from the permanent heap; and that's where I
discovered the memory leak.
On most days, task manager will show the jrun.exe memory starting
off at around 200 MB right after a re-start of CF, but the levels
rise steadily throughout the day, until it reaches 500 MB, and
then I script I have in place restarts CF (when things reach the
500 MB mark, which is when pages start to freeze up). Right now,
CF is restarting on average every 6 hours, which is absolutely
horrendous.
I know some of this is related to the persistent CFCs, but I'm
done my best to go back into the applications I've built and make
sure that variables used/returned by the CFCs are within the
'request' scope, rather than the 'variables' scope. When I run
SQL profiler against my DB server, I'm not seeing any patterns of
the same query re-running endlessly, so I don't think that's an
issue. But, this is the point at which my knowledge of Java's
memory management breaks down. What I probably need to do is set
up a jave profiler like JProbe to see which threads are eating up
memory, but I haven't had a chance to do this yet.
If anyone out there is a JVM expert looking for a few hours work,
let me know :-)
Thanks,
Michael
Michael,
These args are pretty close to what I use on several CF7
standard servers. I
don't see anything that jumps out at me. I wonder where you got the idea
that Jrun is only using 350 megs of memory however. The args below should
put it close to 1200 megs (1.2 gigs). What are you using to make that
determination? If you are using the task manager make sure you
can see the
VM size column.

RE: cfcs good practise
Richard, If your project.add() method is adding a test - yeah, that sounds right. Although I'd call it addTest(). And then internally the project would delegate to a DAO to do the add. So project.addTest() would call TestDAO.add(). project.addTest() would take a parameter of type Test - i.e. you'd first create a Test object, then pass it to addTest(). It's also often convient to have a project.createTest(), which takes as parameters all the basic properties required to create a new Test object and returns the new Test. So you might say: project.addTest(project.createTest(param1, param2)); OK, some details: 1. In this example TestDAO is acting as a collection object, albeit specifically a database-backed collection. You can imagine you could do a similar thing with an in-memory collection like a struct. The natural progression is to make in-memory collections act just like database-backed collections so you can switch between the two, but in practice there are some ColdFusion-specific issues with doing this. 2. project.createTest() is a factory method, which makes Project a factory for Tests. This makes sense if all tests have to live inside projects. If tests can stand alone, you need a different factory, maybe a dedicated factory object that encapsulates the creation logic for your top-level domain objects. You'll probably need this for creating Project instances anyway. If this same top-level factory also has a DAO that lets it manipulate existing Projects, it's starting to look like a service object. 3. Where do all these DAOs come from? You can have your top-level factory know how to create them, and then the creation logic for your domain objects would make sure that each domain object has it's DAO. So you'd have something like (in pseudocode): component myAppFactory: method createTestDAO() return new TestDAO(DSN = my_datasource) method createProject (name_param, description_param) return new Project( name = name_param, description = description_param, dao = createTestDAO() ) Hope this helps Jaime Metcher -Original Message- From: Richard White [mailto:[EMAIL PROTECTED] Sent: Monday, 26 May 2008 8:58 PM To: CF-Talk Subject: Re: cfcs good practise Thanks for your reply Jaime so am i correct in understanding that i should have a project class with methods such as add, remove, find etc... and properties such as name etc... and a test class with much the same methods and attributes, and a materials class, again with much the same attributes then in order to create a collection of the objects so i can manipulate and query the collections i should use dao (and gateways) is this what you mean? apologies, i understand the basic principles of OO but this is the first time i am putting it into practise!!! thanks again Start with just a pure object model. Later you can pick it apart and patch up the bits that don't map real well to CF. So, Projects have Tests. To me, that says that you have a Project class with an instance variable Tests. Tests is a collection that has methods like add, remove, find etc. The elements of the Tests collection are instances of the Test class. Instances of Test *may* have an instance variable Project, which points to the parent project - or may not. The benefit is flexibility in navigating between objects, the downside is another reference you have to manage. I tend to add these back pointers when and if I need them. Ditto for the tests-materials relationship. OK, so how do you do this in CF? The biggest mismatches are: 1) no built-in collection classes 2) the need to avoid instantiating lots of objects The usual workaround is to build the collection object as a (or with a) DAO (see also Gateway) and return a CF query from any method that might return more than one item. Within the DAO you can go crazy with naked SQL, or abstract the SQL with a framework, or both. Just keeping this brief for the moment, but ask for more detail and you shall receive.

RE: CF and SQL Server temporary tables
It's entirely possible for a CF page to change connections in the middle of processing a request, and therefore lose sight of the temp table. It's also possible for the new connection to be one that was previously used by another invocation of the same page, producing the problem that James mentions. You can avoid both of these problems by wrapping the relevant code in a cftransaction - the transaction binds the connection to the CF thread - but, like all locking, you have to consider the impact on throughput. Jaime Metcher -Original Message- From: James Smith [mailto:[EMAIL PROTECTED] Sent: Thursday, 17 April 2008 10:38 PM To: CF-Talk Subject: Re: CF and SQL Server temporary tables If I remember correctly if you have CF maintaining connections your temp table will hang around almost indefinitely, best practice would be to DROP it once you are done with it. Also worth noting that if the page that creates the table can be called multiple times simultaneously (by different users of the system for example) then the second request will fail and error on you because the table has already been created. If you need a truly temporary table you could lock the database (to prevent other requests getting in the way) create the table, do what you need it for, then drop the table and unlock the database. If the table will hold data needed by multiple requests I would look at some way of creating a permanent table and managing the data across requests. -- Jay On Thu, Apr 17, 2008 at 1:13 PM, Rick Root [EMAIL PROTECTED] wrote: so I have a question about temporary tables in SQL Server 2005.

Prefix local temporary table names with single number sign (#*table_name*), and prefix global temporary table names with a double number sign (##* table_name*). What exactly does current session mean as it applies to a Coldfusion request? The life of the request? the life of the transaction, if any? The life of the executing query? Or, since CF maintains the database connection between requests, and pools connections, how does that affect things?

RE: Combine Documents and Databse Records in a Verity Index
Peter, It's certainly possible. The key is to use multiple CFINDEX tags to build the collection. When you execute a search, you then need to do some sort of parsing on the result query to determine how to build the link to the appropriate resource.

RE: Odd database behavior: duplicate key error
Dave, According to livedocs cftransaction by default uses the default isolation level of the database - which in most installations will be either read committed or repeatable read. What you say is true if one sets the isolation level explicitly to serializable. However (I'm sure you know this but it's worth saying), it's hard to overstate the crippling effect on database throughput that serializable transactions can have. I would recommend that even for lightly loaded sites it's worth the extra effort to put a locking strategy in place using cflock, and save serializable transactions for stop the world database maintenance tasks.

Charles, Nothing obvious, but a couple of questions come to mind: 1. Is it just the javascript that's missing i.e. the other content is OK? 2. Is the CFC instance cached e.g. in session or application scope? Also, I know that was only pseudocode, but given that var is a reserved word it looks a bit dodgy.

RE: running jrockit with CFusionMX7 to find memory leak
Have I missed something here? Things like visualgc, FusionReactor etc just tell you how big the heap is. Unless you can pin down the memory leakage to particular moments in time, this doesn't help much. We need to know what's in that heap. From what I've seen the only one of Sun's tools that runs on the 1.4.x JVM is visualgc. The heap analysis tools require later JVMs, which CFMX7 does not support. That leaves us with things like OptimizeIt and JProfiler. I'd love to know if there's another way. I have a memory leak on my production server which I've been unable to reproduce on dev, and don't want to load down production with instrumentation. My current plan is to upgrade to CF8 and a) see if the leak goes away and b) get into the JVM 1.6 good stuff like JHAT.

I guess if we stick to short methods (20 lines) the set of methods required to be implemented by duck-typed arguments is not too hard to work out just by reading the method body. In fact if we wanted to soup up the code introspection I'd think this is something that could be determined automatically by inspecting the CF parse tree. Obviously we couldn't follow the call tree as we don't know which implementation to look at until runtime, but we could at least determine method names and number of arguments. Beyond that, there's still a need to document somewhere central the semantics of each duck-typed method - it's all very well to know that a method will take as an argument any object that implements a setID() method, e.g., but it's important that the caller and implementor share a common world view regarding what an ID is. cfinterface or the abstract superclass technique provides a place to put that documentation, and it would be nice to have a documentation mechanism with no runtime impact that is similarly structured and introspectable.

That reminds me of another idea for documenting intention in a structured way that *doesn't* have a performance penalty. I'm certainly not the first person to point this out, but you can add arbitrary attributes to the cfcomponent, cffunction and cfargument tags that then appear in the metadata. I'd love to see the community generate some momentum on a standard set of metadata to aid in code introspection. For example, if converting code from typed to untyped for performance reasons, instead of removing type and returntype attributes, why not change them to _type and _returntype, thus documenting the original intention?. If ducktyping, the _type attribute could read any CFC that implements getID() for example. It would then be simple matter to adapt CF's builtin CFC introspection to read these attributes. Similarly, if you have a function in a superclass like this: cffunction name=doSomething cfthrow Subclass responsibility /cffunction why not add an abstract attribute to document the intention. From there it's not too hard to parse the metadata into XMI and produce a UML diagram, if that's what floats your boat. And I know there's somebody out there (sorry -forgot who you are) who uses cfproperty tags to document composition relationships. This *is* just documentation, *not* an attempt to add Java-style annotations, and isn't necessarily any more accurate than any other documentation.

RE: Init method and getters / setters in cfc
Somebody (Peter Bell, I think?) has a comprehensive solution involving lists
of properties where on a per-property basis you can define whether it is
gettable or settable for each access type (i.e. public, private, package),
and on a per-class basis you define whether properties are addable and what
happens when a non-existent property is accessed. This is non-trivial and
gets around the infinitely mutable object problem, and the
self-documentation issue.
The naked get(key, value), set(key, value) (maybe simplified for use as an
example?) is really just a way to expose the variables scope to the world.
I wouldn't want to do that in most cases, and if I was really doing a quick
and dirty hack I'd just use the this scope and save myself the trouble of
even writing the generic get/set.

While I don't know what is *right*, here are the arguments that I have
heard against the generic getter/setter:
* The CFC is not self documenting. Looking at its functions does not
give you any insight into what it can set/get.
* Not clear on what should be returned if an invalid get is requested.
* It makes extending a component more difficult because the parent
component now has to be smarter about where it looks for its data.
Take that with a grain of salt ;)

A lot of cfc's using init and 'good' OO practices have functions like
getDSN(), setDSN('Blah') littered throughout. Can I ask any guru out
there why you wouldn't use simple get('keyname') and
set('keyname','keyvalue') like the following?
cffunction name=get access=public output=no
returntype=any
cfargument name=name required=true type=string
cfreturn evaluate('variables.' arguments.name) /
/cffunction
cffunction name=set access=public output=no
returntype=void
cfargument name=name required=true type=string
cfargument name=value required=true type=any
cfset variables[arguments.name] = arguments.value /
/cffunction
Then instead of littering your cfc with numerous getters / setter, you
have 2 methods that should be able to handle simple or complex values
without any problems with much less code.

RE: New developer vs. Veteran developer
I agree about upgrading the bean counters or at least adjusting their attitude. The fact is that the productivity gap between an excellent developer and a merely competent one can be enormous, a factor of 10-20, and it can vary depending on the task. I believe this is a finding arising out of formal research, not just anecdotal (sorry, don't have the reference). In fact (and this is anecdotal now) in a small agile shop an even slightly sub-par developer can be a net drain on team productivity, and you may not diagnose this until training time is over, crunch time has come and gone, the developer has moved on and you now need to do the first major upgrade of the subsystem they wrote. You don't see anything like these extremes in most professions (say, counting beans), so bean counters can find it hard to accept. I'd also echo Barney and say that years of CF experience is much less important than years of development experience. I would expect a top notch developer who had never used CF to be teaching *me* things about CF after 3-6 months. And finally, years of development experience is much less important than years of actively pursuing professional excellence. For example, a CF developer of 10 years experience who has never heard of patterns and never played with Java integration isn't worth much IMHO. NOT because I expect them to use patterns, or even OO - but if they are actively seeking after best practices, the WILL be aware of these things, WILL have investigated them and WILL have coherent reasons for using/not using them. So, to finally give my answer to the question: developer A = webmaster type who can do ColdFusion but doesn't really get development as a profession developer B = CS grad with solid skills but maybe a bit of a plodder developer C = CS grad with talent and great attitude developer D = Zen master with 10 years of the pursuit of excellence Productivity ratio B:C:D ~ 1:2:4 What about developer A? After six months, D will have mentored A, B and C, done his/her own work, collaborated with C on improving the teams practices, completely rewritten all of A's code, and participated in interviewing for A's replacement. So A's contribution is that D is now very tired.

RE: Subversion Tutorial Posted
I don't reckon this thread is long enough yet, so here's some more... There are so many ways to use Subversion that it's easy to be in violent agreement. We all agree on this: Don't break the build. Make sure you thoroughly test before you commit. And be sure to backup your working copy. But we interpret the words differently: Andrew: the build = the latest revision Tom: the build = the approved tag Me: the build = the latest revision from trunk Andrew: commit = the usual subversion commit Tom: commit = create an approved tag Me: commit = merge my personal dev branch into trunk Andrew: backup = filesystem backup of working copy Tom: backup = commit working copy into repo, then backup repo Me: backup = commit working copy into my dev branch of the repo, then backup repo And thereby end up with three different procedures that look different but in fact do the same thing (maybe with slightly different emphases). We all create abstractions for a living here, surely we can cope with that.

You and I are on the same team working on the same project I make some changes to my code, and I have not written any TDD test cases and just submit my work into subversion and go home, while I am travelling home I am involved in a car accident and put into hospital and out of action for a day or 2... Thanking god its not serious... Anyway, the code that I submitted broke the website / application in a major way. now its your Job or someone elses to step through the revisions to see what I did to break the code. Now on top of this, you have one hour to figure this out before you demostrate the new changes that had been made for the last few weeks. However I can't be contacted cause I am still not very coheriant But due to an unforseen problem, I not only broke the latest version (Note: version not revision) and forced others to waste time finding out what I did to break the latest build / code. In the meantime the client is being patient, and you have to put him/her off for a day or two to get this sorted out, then he begins to wonder what he/she has paid for and is becomming a little impatient with you. Are you begining to understand my point now, it doesn't matter what you think in the long run you might have saved more time on the project if I did not commit this code and stopped everyone else from getting their job done. Subversion is a version control system, with the ability to handle revisions. It is not a revision control system and should not be treated that way. The mentality of a developer should be take action against all possible problems, and if my code is going to break the latest build at the 11th hour or not I shouldn't commit it until I am 100% happy with the fact all my unit test cases have passed and I have covered 100% of code in my tests. Bobby, your methods might work. But it can be improved and thats what I am trying to say to you, why do you think the java community adopted the agile and TDD aproach, and use subversion for what it is designed for.

RE: Subversion Tutorial Posted
FWIW, our procedure (having created the repo) is this: 1. Identify a batch of requirements totalling 1-3 weeks work. 2. Create a branch from the head revision of trunk. This is a branch of the entire system, not just the subsystem under development. 3. Assign the job to a developer, who will check out that branch as their working copy onto their local CF environment. 4. The developer can then use that branch as backup/undo if they want to. 5. 1-3 weeks later when finished, merge the latest trunk revision into the branch. 6. Then, after passing both unit and integration tests the branch is merged back into trunk. 7. Back to step 1. In the rare (and undesirable) instance where the work can't be completed due to external dependencies or some overriding priority, the developer can simply park that branch and start work on a second job with a second branch. Obviously parking a branch for too long has all sorts of hairs, but not being able to do this can be even hairier. In the rare (but desirable) instance where we want to just futz around with some new ideas, same story - create a second branch and go for it. This one might never be merged back to trunk. If two developers are working on the same batch, we may check out a dev branch to two different machines, but in practice we rarely do this. We either pair program or work on something different. Meanwhile, maintenance fixes and small tweaks (meaning one hour fixes) continue from the trunk, which is checked out to a shared CF environment. The head revision of trunk must be deployable at all times (i.e. it is the build).

RE: Unit Testing A Web Interface
and automation of cross-domain testing. You can run cross-domain scripts
manually, but the automation is experimental and didn't work for me. But
it's hard to see how checking cross-domain workflows could be called unit
testing.
I use selenium a lot, but if you just want to unit test a single form
post, you can also do this in cfcunit or cfunit pretty easily.
1. Use a global test mode flag to make the form think it's been POSTed to:
if (CGI.request_method is POST or StructKeyExists(Request,
flgFormTestMode)) {
// processing code here
}
2. Instead of cflocation, use a UDF which checks the same flag and prints
out the URL if the flag is set.
3. Use cfunit's AssertOutputs function (or steal or write your own for
cfcunit) to run the form processing module, capture its output and run a set
of assertions agains the output.
So then your test looks something like:
Request.flgFormTestMode = 1;
FORM.myField = hello;
AssertOutputs(type=module, template=/mymodule.cfm, expected=Redirect:
nextpage.cfm);
This has the advantage that it's easy to simulate some of the bizarro form
transmissions that only real users and spambots seem to be able to create -
you know, missing fields, strange query string parameters, a list of 2,000
porno sites in a form field that's supposed to be a yes/no radio button...
So I tend to use selenium for success scenarios and typical exceptions, and
cfcunit for strange edge cases.

I have an idea of what a Unit Test is for code classes, but I have no
idea how this is to be done for a web interface? Does anyone have any

that attempts to submit a form with bad value sets? Are there apps out

In my application I have allot of queries that pull data dependant on the user that is currently signed in using the user_id which sits in their session. Now for the moment I pass this user_id in as an argument to my functions that contain queries, like this. cffunction cfargument name=userid cfquery SELECT somthing FROM wherever WHERE userid = #arguments.userid# /cfquery /cffunction I then call this function by doing the usual MyObject.myFunction(Session.UserID) Now is this the best way of doing this? Presumably there is a slight vulnerability in security as anyone could effectively pass in any old user ID and have it pull their information from the database. What I'd really like to do it have that WHERE clause interact directly with the SESSION scope to collect that user ID, that way the user HAS to have an active session and will only ever be able to retrieve their information, and to get an active session with a populated user_id they must have been authenticated.

RE: What conditions would cause a new jsessionid to be assigned to a user session?
Jason, Not sure if you saw my reply to the now somewhat out of control thread on CFC locking, so here it is again: I have seen a problem where a proxy cache was mixing up user's sessions so they would actually see each other's data. The actual mechanism was that the proxy would return the cookie headers (to the browser) out of proxy cache. A lot of the time, of course, the cached cookie would be referring to an expired session, so it would look like a session timeout. We developed a mechanism for comparing the cookie sent to the browser by the server with the cookie that the browser sends back - where they're different, there's been a cache mixup. We resolved this with no-cache directives. I'm presuming you've tried that, but it's suprisingly difficult, so it might be worth another look.

Everything has been setup in CFadministrator correctly, as 95% of the users are able to stay logged in for the 2hr time frame and have no problems. With the small percentage of users that are not being able to stay logged, the timeout is random and the server assigns a NEW jsessionid to them. Of course, when this happens all of the user info that is stored in session is lost, therefore they are gracefully kicked out of the site and asked to log in again.

RE: Using CFCs in session scope - need cflock help
Jason, If you are seeing the session ID values change (as per the earlier thread) then the user is getting a new session. Whether there was a race condition in the old session has nothing to do with it. The request with the new session ID is starting with a clean slate and is not even aware the old session existed. AFAIK, there's only one thing you can do in code that will cause somebody to get a new session ID, and that's destroy their cookie with a CFCOOKIE or CFHEADER tag. If you're not doing that, the problem must be at the HTTP level, and all the previous suggestions about browser bugs, proxies and caching come into play. I have seen a problem where a proxy cache was mixing up user's sessions so they would actually see each other's data. The actual mechanism was that the proxy would return the cookie headers (to the browser) out of cache.

The program I studied there really focused on OO design and use. So I've been somewhat brainwashed, but I really believe in it despite this. So when I took on the current project my employer wanted the site cleaned up. It was a mess prior to the redesign. I chose to use components rather then using cookies or individual session variables because I love the structure and organization that a nice, neat wrapped up component providesand I love reusing code instead of having copies of it everywhere. Everything is much more consistent and logical. Instantiating them in session was a natural choice since, in theory, the data should be maintained for the user's session across all pages. The main user component only contains DATA relevant to the user and methods that deal with this data. I honestly don't see a huge problem with this because it's not a huge amount of code. RAM is not really a concern to us, the machine is adequately equipped. So now we're having issues with the site timing out users prematurely and randomly. We have verified that what is causing this is that the user is getting a NEW jsessionid from the server. What we don't know is WHY this is happening. Responses from another post I made where that there are a number of causes, many which are unrelated to actual code. What I really need to determine is if the lack of cflock in appropriate places is the culprit. I see that there are pros/cons to using cfcs in session, as have been noted in most of the responses here, but I need to pin down what is causing it. If anyone has any helpful advice please send it my way. If you want to scorn me for using CFCs in session scope, please keep your comments to yourself unless you truely feel it is relevant to my problem.

RE: Using CFCs in session scope - need cflock help
Andrew, I just don't see what your code example has to do with race conditions. cfset is an atomic operation (didn't used to be, but that's been fixed) so no race condition is possible. Using locks like this is a bizarre but mostly harmless practice that is only common in ColdFusion because of bugs in earlier versions. What *isn't* harmless is the notion that doing this in any way protects you from a real race condition. I'm preaching to the choir here, but for the record, a race condition looks like this: 1. I query some piece of shared state. 2. Some other thread or process changes that state 3. I perform some operation that depends on the state not having changed. Even if we restrict the problem to, say, just the CF session scope, the only blanket approach that will prevent race conditions is to single-thread the whole session. Locking single cfset tags in setter functions will do nothing for you. If you don't want to single thread the session (and if you're doing frames or AJAX you shouldn't), you need to understand for every operation what shared state it depends on and what the impact of a change in the shared state would be. If there would be an impact you care about, put the querying of the state and the operation where you use it as close together as possible and wrap them in a lock.

RE: Using CFCs in session scope - need cflock help
Andrew, OK, I'm officially confused. I remember it being nutted out, and the conclusion being that you *don't* need to lock when writing to a session variable. A simple cfset Session.x = y can't possibly have a race condition, right? It *may* be part of a multistatement operation that creates a race condition, but in itself, no way.

Anytime one write to session.somevariable, there is a chance that there could be a race condition. I am sure you know that, and if the session containes a CFC then the rules of race conditions still need to apply.

We have also seen the could not open error. After much investigation, we found that this error was due to a CF error that would naturally not propagate through to excel. The way we fixed it was to run the report with the cfcontent/cfheader commented out, and see the actual CF error, fix it, uncomment the cfcontent/cfheader and run it again. In every case, we were able to fix the problem. Usually it was a reference to an undefined variable causing the problem. Also, you should probably wrap your URL variables in a urlencodedformat() for good measure (we also encrypt ours, but depending on your requirements that may not be necessary). Cheers, Kris A question relating to cfcontent and session variables, with a hint of URL variables. We are migrating from a relatively open system to one that has a login and session management. We have stumbled across something that seems to be behaving oddly, though I don't know why. We have a coldfusion page that will generate a report as HTML. If the user selects a button to save it to excel, it runs the same page, but inserts the CFCONTENT TYPE=application/vnd.ms-excel reset=yes CFHEADER NAME=Content-Disposition VALUE=filename=myreport.xls at the top. The only other difference, is the variables to generate are passed through as URL variables. Before adding the session, they worked fine. Now though, and it is not all situations, it almost seems like IE or Excel are trying to open a new instance of IE outside of the session in an attempt to download the file. As I said though, it is not all. This link... reportactionoutput.cfm?DATEPARAMS=Dec 09, 2005DATEPARAMSLENGTH=1reportlevel=Nationalreporttype=ABCreport param=465saveToFile=yes does not work, with excel popping up an error message saying Cold not open http://mysite/reportactionoutput.cfm?DATEPARAMS=Dec 09, 2005DATEPARAMSLENGTH=1reportlevel=Nationalreporttype=ABCreportparam=465 saveToFile=yes Now, if I run a slightly different report type, the exact same url with maybe another parameter like this reportactionoutput.cfm?DATEPARAMS=Dec 09, 2005DATEPARAMSLENGTH=1reportlevel=Nationalfocusstate=CAreporttype=ABCre portparam=465saveToFile=yes It opens fine, no issues. The only thing I found that may fix the problem is changing the spaces in the url variable to %20 This falls into different reports doing different things, not common code so there is a lot of places to change it, with no full assurance that this will fix the issue.

RE: Using CFCs in session scope - need cflock help
It's looking pretty bleak - we can't store CFCs in session because they take too much memory, and we can't instantiate per request because it takes too much CPU.Thank heavens for procedural programming. ;) Seriously, though, I have high hopes of CF8 in this respect. We have the language features for OO, but trying to think OO with one eye on the performance monitor is just a bit too schizoid for me. Now it's up to Adobe to tune the app server.

They can be very memory intensive so giving each user their own session CFC which is identical to ever other users doesn't make any sense as it would be needless consumption of memory space.

RE: Coldfusion Server Issues
What could cause cross-interference between sites? Some ideas: 1. Contention for shared resources e.g. you keep a file open somewhere, or each site has a logging thread that keeps a lock on some table. 2. An insidious one can be where you inadvertently use the same application name, so the two sites keep blowing away and reinitializing the shared scopes. 3. Mapping - you've got a mapping for one site that's a real directory in the other site. The mapping takes precedence, so you're executing code in the wrong context. 4. Memory overload - if you're loading a lot of data into shared scopes, the GC could be thrashing. I'd highly recommend a management tool like Fusion Reactor. The ability to look into the guts of a running thread can clear the fog in a microsecond.

How can you create a path using dot notation to a file that's above your calling page? ~| Upgrade to Adobe ColdFusion MX7 Experience Flex 2 MX7 integration create powerful cross-platform RIAs http:http://ad.doubleclick.net/clk;56760587;14748456;a?http://www.adobe.com/products/coldfusion/flex2/?sdid=LVNU Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:268921 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4
RE: moving from CF 4.5 to 7.0
There's an Adobe document called cfmx7_migrating.pdf. We basically just worked through it. Every issue we had was described in this document - things like cfmail, cfdirectory, TimeFormat etc. I might add we only needed a dozen changes in several thousand modules. The only thing we found hard to find by examining the code was the change in the structure dot notation handling - in 4.5 if you forgot to do a StructNew(), then cfset a.b = c, you end up with a variable whose name is a.b. In 6 7 you get an error telling you a is not a struct. Let me know if you want me to email you a copy of the document. Jaime Metcher -Original Message- From: Nathan C.

And 4.0 to 6.1 before that - on another box. For the most part the update is going well. I have a few niggling details with how variables are referenced, but that has been the biggest issue to date. The code-scanner in the administrator can be helpful but it will not catch everything. It will probably depend a lot on how many less obscure features you use too - if any. The one that reads and writes windows registry is the one that comes to mind. -Nate -Original Message- From: Mark Fuqua [mailto:[EMAIL PROTECTED] Sent: Monday, February 05, 2007 3:15 PM To: CF-Talk Subject: RE: moving from CF 4.5 to 7.0 No personal experience, but I think the info you find about 4.5 to MX or especially 6.1 would translate well. I think 7.0 was mostly about adding features and fixing bugs, not a big rewrite of the code base.

We do have a Dev box, so we can play a little before doing it on the production boxes. I'm finding several posts about going from 4.5 to 5, or MX and the issues people ran into however, I am wondering if anyone who has made the jump from 4.5 to 7 can provide details to any issues they might have experienced. ~| Upgrade to Adobe ColdFusion MX7 Experience Flex 2 MX7 integration create powerful cross-platform RIAs http:http://ad.doubleclick.net/clk;56760587;14748456;a?http://www.adobe.com/products/coldfusion/flex2/?sdid=LVNU Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:268766 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4
RE: Eclipse/CFEclipse problem???
Maybe unrelated, but there is a current issue with cfscript that produces these symptoms. http://trac.cfeclipse.org/cfeclipse/report/1 Jaime Metcher -Original Message- From: Jason Holden [mailto:[EMAIL PROTECTED] Sent: Monday, 5 February 2007 8:35 AM To: CF-Talk Subject: Re: Eclipse/CFEclipse problem??? I'm having a small problem with Eclipse/CFEclipse. Anytime I type the world parent into the editor it causes Eclipse to freeze. javaw.exe pegs my CPU at 100% and I have to forcefully kill the process and restart Eclipse. Has anyone else had this problem? UPDATE: This is not just associated with typing parent, i guess it was just a coiencedence that it happened each time. I'm trying edit javascript and after a few minutes of editing the Eclipse IDE becomes unstable and javaw.exe uses 100% of the CPU. ~| Upgrade to Adobe ColdFusion MX7 Experience Flex 2 MX7 integration create powerful cross-platform RIAs http:http://ad.doubleclick.net/clk;56760587;14748456;a?http://www.adobe.com/products/coldfusion/flex2/?sdid=LVNU Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:268618 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4
