RE: Passing URL variables in a dynamic form action

2005-01-03 Thread Martin Parry

Mike - If you do a CFDUMP of the CGI scope you will see amongst other
things that you can use action="#cgi.script_name#?#cgi.query_string#"

p.s. What are the CF developer contract rates like in Oz at the moment ?

Sorry this has been covered before but I can't bring my addled brain
to bear on the search to find it ... Perhaps some kind soul will help
me out ..

I have a form that is to appear in various locations in a dynamic
site,  - i want to pass the current page, with url variables to the
form as the action page, but i can't remember how ..

For example on a  page /goArticle.cfm?pid=548978  I want to have the
form tag as:

IIS6 on Win2K3 with CFMX6.1, connection hotfix

2005-01-03 Thread Micha Schopman

I while ago I saw a Macromedia article about a slow connection between
CFMX61. and Win2K3's IIS6. This was due to bugs in IIS6, but Macromedia
provided a workaround to overcome the slow connection between the two. 

I just can't find any article on the Macromedia support website about
this, and I am convinced it existed. Someone happens to know the
article? I have searched for IIS6, Win2K3, CFMX6.1, ISAPI, Connector,
etc. but all I get is rubbish.

Typesafe enum design pattern (another go)

2005-01-03 Thread Taco Fleur

 Just trying to implement the Typesafe Enum Design Pattern in ColdFusion,
and am looking for some feedback/input on the following code.
 
I have tried to get some feedback before on the Singleton design pattern,
but got not one response, so I am thinking;
1. This is not the list to post to for feedback, only problems.
2. There is no interest in these type of posts.
3. I was so way off that it wasn't even worth replying.
4. Fill in..
 
So here is another go at another design pattern..
 
 Following is the code to call the CFC
**

DataType = createObject( "component",
"_resource.class.database.microsoftSQLServer.DataType" ).init();







for ( Constant in DataType.instance )
{
 writeOutput( DataType.instance[ Constant ].getLower() & "" );
}




**
Following is the CFC itself

**



 

 

 
 

 
 this.instance = structNew();
 


 

  
  // Public static
  newConstant( name = "BIGINT", lower = -9223372036854775808, upper
= 9223372036854775807, type = "numeric" );
  newConstant( name = "INTEGER", lower = -2147483648, upper =

  // Same as Decimal constant
  structInsert( this, "NUMERIC", this.DECIMAL, false );

  // Return the instance of the Object

QofQ, buggy behaviour

2005-01-03 Thread Micha Schopman

I am experiencing weird behaviour on our production server, running the
exact same software & hardware configuration as our staging server. The
staging server returns everything back just normal, but the production
server doesn't like it. It is a very simple piece of code.



SELECT Name, Size, DateLastModified
FROM qryDirectoryContent 
WHERE Type = 'File'
ORDER BY Name


SELECT Name, Size, DateLastModified
FROM qryDirectoryContent 
WHERE Type = 'Dir'
ORDER BY Name






The message I get is this, and maybe it is because Size is a reserved
word in SQL, but still then, staging returns everything back just
normally.

Error Executing Database Query. 
Query Of Queries syntax error. Encountered "Size" at line
0, column 0. Incorrect Select List, Incorrect select column,

The error occurred in C:\persist.io.cfm: line 5 
3 : 
4 : 
5 : 
6 : SELECT Name, Size, DateLastModified
7 : FROM qryDirectoryContent


When I put quotations around the column Size, it returns the string Size
instead of the column

But still buggy .. this really is annoying.

A simple datatime formatting of datelastmodified throws an error just at
random dates.

coldfusion.runtime.Cast$DateStringConversionException: The value
"woensdag 8 september 2004 12:57:01 uur CEST" could not be

Perhaps LSDateFormat would be more reliable with locale-specific date
formatting and parsing?

I don't know enough about local specific stuff in CF, but just a

Re: Passing URL variables in a dynamic form action

2005-01-03 Thread Mike Kear

AH!! yes.. I KNEW it was right in front of me.  But I'm sorry given
it's a hot summer, and still new year hangover time, my brain just
wasn't working.

Thanks

As to contract rates, I'm not a good person to ask. I'm bloody glad to
see the back of 2004. It was the worst year financially for me since
1981.   For the last 11 years, I've earned about 2/3 of my income from
freelancing, and in 2004, up till November 15, I had 14 paid days
work, and all of that at a rate less than half what I was earning for
most of the previous 5 years.   Most of the people I contacted during
the year - HUNDREDS of them - simply didnt have the manners to respond
in any way, so I dont know how I did with them.  Never got a response,
even to advertised positions.  Of those I did get to talk to,  most
said they weren't making any new dvelopment in ColdFusion, only doing
mods and bug fixes on their current sites.

Thats what prompted my question a few weeks ago that caused such a
stir - who's actually selling coldfusion servers in Australia - who's
actually working to increase the market for us..

I've gone and got Macromedia CFMX certification - to advanced level no
less - and I'm hoping that might prove to the people who were so
dismissive that they couldn't even bother to send an email that I have
both practical and theoretical skills and I know what i'm talking
about.

However others said they were having a bumper year, and that the
coldfusion market here was strong and go-ahead.  I guess you have to
be on some kind of 'inner circle' or something.   Or know the secret
handshake.

I finish 4 weeks good work at a Government Department in a couple of
weeks, and I'm back hunting again.   So there's yet another big
department (they say they have Australia's largest intranet)  doing no
new development in CF and planning to move to other technology.  
Frankly I dont relish hunting for work during January.  But that's how
it's turned out.

My advice?   Don't sell up and come to Australia if you plan to rely
on ColdFusion development for your source of income.

Sounds like you've had a shitty time of it lately.

Yes, our intention has always been to move to Oz, as I was offered CF
work at $75 per hour about 3 years ago (I'm a slow mover so never got
round to doing it :$ )

I noticed you had advanced - well done. I've bought Ben Forta's study
guide and I'm gonna refresh my memory and see what new features I've
missed. I've been simply too busy doing the grind to keep up to date.

Hope things improve for you !!

.. "ColdFusion .. euhm.. what is that?" ;)

SOT: RegEx help

2005-01-03 Thread Todd

I would post this to the RegEx list, but I'm short on time and the HoF web site 
is giving me fits when I try to subscribe. :)

I just got a major problem dumped in my lap.  We have about 1/2 a gig of pure 
HTML files that are screwed up and the boss wants them fixed yesterday.  I'm 
writing a CF script to automate the updating of all of these files, but I am 
not very good with RegEx's and the guy who was good with them is no longer with 
the company.

All of the HTML files contain a line somewhere in them that looks like this:

Actors: Jane Doe,Sally Smith,Mary-Lou,Bob Dobbs,Dude,Stan Cox, 
etc.

I need find that line and make it look like this:

Actors: Jane Doe, Sally Smith, Mary-Lou, Bob Dobbs, Dude, Stan Cox, 
etc.

Basically, I need to make sure there is at least one space after each comma.  
There can be more than one, so checking for an existing space isn't an issue.

I would be rather grateful if anyone could help me out with this.

RE: IIS6 on Win2K3 with CFMX6.1, connection hotfix

2005-01-03 Thread Kelly Tetterton

Could this be what you're referring to (posted to CF-Talk, 9.22.04)?:



A customer recently pointed out to us that our IIS6 Windows 20003 web srever 
connector performance appeared substantially worse than the web server 
connector performance on IIS5 and earlier.

We did a little digging and came upon the Microsoft knowledge base article 
below.

The customer reran his tests using the suggested resolution and confirmed that 
with the suggested registry setting our IIS6 performance is slightly better 
than our IIS5 performance, as it should be. 

We'll publish this as a TechNote shortly, but if you're on IIS6, check it out.

The ISAPI connector is using the synchronous WriteClient() API.  Windows 2003

I while ago I saw a Macromedia article about a slow connection between
CFMX61. and Win2K3's IIS6. This was due to bugs in IIS6, but Macromedia
provided a workaround to overcome the slow connection between the two. 

I just can't find any article on the Macromedia support website about
this, and I am convinced it existed. Someone happens to know the
article? I have searched for IIS6, Win2K3, CFMX6.1, ISAPI, Connector,
etc. but all I get is rubbish.

Well, it seems to me that there should be a space after every comma, 
anyway, so couldn't you just do a simple replace() to replace commas 
with a comma and a space?

Re: SOT: RegEx help

2005-01-03 Thread Ben Doom

The reason that I ask is that I don't see a quick way to do what you 
originally asked.  But there are ways.  Here's the quickest (from a 
coding point of view, if not a processing point of view) that I can 
think of

There's a UDF on cflib.org called ReExtract() (I think that's right) 
that you should be able to use like this:

toBeReplaced = reextract(text, ".*?.*?");
text = replace(text, tobereplaced, replace(tobereplaced, ",", ", ", "all"));

Loop on that until you've got them all (assuming there's more than one 
per page).  Or, if reExtract() can produce an array, you can loop over 
that.  I've never used it, so YMMV.

Anyway, this is (obviously) untested, but should point you in the right 
direction.  If you need more help, feel free to ask.

How does one get a view other than the graphical representation?  I
poked around a bit but didn't know what to look for...

> It looks like eliminating some rows earlier may help here:

I implemented your latest version of the query and it actually
returned in the same amount of time as your version previous, to the
second.

But, it is a huge improvement over the way it was when you began
offering help, for which I'm grateful.  It seems my best permanent
solution will be to create a separate db and use DTS to bring the data
I need for my reports into a more concise, report-friendly structure,
and with your improvements in place the current system will be
workable while I work on implementing that.

Thanks for helping me learn a few things about sql!

JSP Question (Does query caching existing)

2005-01-03 Thread Ciliotta, Mario

Hi,

Sorry for asking a JSP question here but I have not been able to find a
mailing as good as CFTALK for Java/JSP issues.

I am in the process of converting a CF application over to JSP running under
WebLogic as practice to see how long it takes to do the same coding vs. using
CFMX. 

In my CF application, I cache my queries since the data really changes and to
handle this I have a scheduled job that runs to flush and update the cached
queries if there are any changes.  Is there a way to cache the query results
in a JSP page?  I have to have the page requery the database every time
someone goes to page to look up an item.  Basically the items only change once
a year, if that.

Also does anyone know of a good JSP/JAVA equivalent of CFTALK.

Thanks
Mario

But the problem is both with 'MS SQL server' and with

your database (except for the indexes) and got the following

RE: Including Coldfusion content in an asp page

2005-01-03 Thread Burns, John D

I believe BlueDragon (and maybe others) support some sort of CFM/ASP.net
including back and forth, but if you're just talking standard
CFMX/ASP.net or ASP you'd just have to use an equivalent of CFHTTP to
call the CFM page or maybe use an IFRAME or something to load the CFM
into.  As far as I know there is no way for ASP to trigger the CFM
server to parse the pages and return the content...at least no way that
is supported.

No, I don't think you can do that with an ASP include. You could use HTTP to
invoke the CF URL directly, although this would be pretty inefficient. There
are various ActiveX controls that allow you to do this, although I don't
have much experience with them in production applications.

RE: shopping cart, session variables - best practices

2005-01-03 Thread mayo

Sorry for not responding earlier. My laptop was stolen. A big mess.

I'm on a shared host so the RAM is somewhat limited. However the client is a
small clothing and jewelry business. They have two stores and this is their
first venture into on-line sales. Currently they get about 200 unique
visitors a week. I don't think they will have over 10 concurrent users of
their shopping site for quite a while.

I think we should really find out the capabilities of Mayo's server/host

eComm sites I have seen superb performance using the method described.

If, however RAM is not a problem, he isn't experiencing high volumes and
is not on another server with xxx websites who all make excessive use of
session variables, then yes - maybe he should use session variables..

Storing application- and user-specific data is what precious RAM is for!

In an application environment with a single application server, you will
typically achieve significantly higher performance under load by storing
things in memory rather than fetching them from the database for each
page
request. You may need to provision your server's RAM adequately to
ensure
you have enough for the number of concurrent users you need to support,
but
RAM is comparatively cheap.

I don't think there's anything built into JSP to do this directly. I think
that the Hibernate service lets you do this, however, so you might want to
take a look at that:

Regarding the original post I can't see any reason to use cflock at all.
Initializing the application variables, I would hope, would not entail using 
user specific values. If the initialization is the same no matter
which user does it, and you won't crash the server anymore, then why 
lock it?

RE: comma separator

2005-01-03 Thread Dawson, Michael

You can't change the comma delimiter from submitted form values, but you
can use your own delimiter, such as the pipe "|", when creating your
select box.

Then, the user selects multiple addresses such as:
French Lick|IN,Evansville|IN,Houston|TX

Then, when you perform the query, you can replace "|" with a comma (and
space) as needed.

When you're looping over the values you could just increment the list by
2 on each so the first and second values go together, etc.

It would all depend on what would happen if two threads tried to run
the "long initialization process" at the same time. If the code
creates objects and builds dependencies using application scope, it's
entirely possible you would get an inconsistent data setup.

If you're just setting a bunch of scalar variables, you won't have problems.

In other words, it all depends on whether the initialization code
itself could be subject to race conditions.

Default Instance Values in CFC Bean

2005-01-03 Thread Dawson, Michael

Below is a simple component/bean I created to manage a simple database
table.  Please notice that I have a sortOrder which is a numeric type.
I specified "numeric" for the argument type as well as the return type
in the setSortOrder() and getSortOder() methods.

That means I need to specify:

in my pseudo-constructor area or I will get an error about a non-numeric
return type if I call the method with an "empty" CFC.

My final goal is to populate form fields.  If this is a new record, I
want the form fields to be empty.  If I am modifying an existing record,
I want the form fields to display the current record's values.

This is a simple example using a numeric value that I can easily set to
"0" or "-1" or some other non-valid value.  However, how would I
"default" a date/time return type?  I can't imagine any date/time that
would not be a valid date/time value.

Therefore, if I use:

my getDateStart() method will throw an error because "" is not a date.

If I use:

this is a valid date but not semantically correct.

Is the solution so simple as to specify string as the argument type and
return type of all methods?

Thanks
M!ke

Bear in mind that form data is untyped by definition - it is all
strings. If you are using a bean to "mirror" a form, all of its
setters and getters should traffic in strings, not other data types.
The reason for that is that if user input is invalid, you won't be
able to set the bean values so you're bean won't get a chance to
validate data. The data from the bean will be valid after calling some
sort of validation method, not before.

Form data management is one of those cases where you often need a data
bean separate from your business object - since the business object
should only traffic in valid, typed data but the bean, by definition,
can't since it is dependent on the form.

This is more about user input validation strategies than default
instance variable values.

Hope that helps?

As usual, you have helped tremendously.

I was using in-line, procedural validation (similar to one of Barney B's
example), but I didn't really consider having the bean validate itself.
I'm going to spend the rest of the afternoon building in a validate
method to my bean and see how it makes me feel.  I like how you
explained it.

Bear in mind that form data is untyped by definition - it is all
strings. If you are using a bean to "mirror" a form, all of its setters
and getters should traffic in strings, not other data types.
The reason for that is that if user input is invalid, you won't be able
to set the bean values so you're bean won't get a chance to validate
data. The data from the bean will be valid after calling some sort of
validation method, not before.

Form data management is one of those cases where you often need a data
bean separate from your business object - since the business object
should only traffic in valid, typed data but the bean, by definition,
can't since it is dependent on the form.

This is more about user input validation strategies than default
instance variable values.

Hope that helps?

"Proper Use" of Instance Variables

2005-01-03 Thread Dawson, Michael

I have a simple CFC that has a few instance variables in it.






...




In this component, I have the pairs of getters and setters such as:


...



...



I also have a validate method that needs to check the values of the
instance variables.  Which is the "better form" of accessing the
instance varibles?

1. ...
Or
2. ...

At first glance, the second option is shorter and would still
encapsulate any logic even inside its own CFC.  Would there be any
substantial overhead with calling a method over an instance variable?

Thanks

In the thread where I gave the inline validation example, I also

wasn't recommending inline validation (if I recall correctly, I
recommended against it, for many of the same reasons Sean listed),
merely illustrating two different approaches for doing your

individual getters and setters.

Re: "Proper Use" of Instance Variables

2005-01-03 Thread Barney Boisvert

This (or something very similar) has come up before.  I personally
like using the getters and setters everywhere, as they are the 'real'
properties of the CFC, not the instance variables.  At least that's
the theory.  As for overhead, there definitely is some, but it's going
to be quite minimal, and can be safely ignored, IMHO.

Re: "Proper Use" of Instance Variables

2005-01-03 Thread Nathan Strutz

Personally, I like to use the raw instance variables, as it's easier to 
avoid the recursive caller mistake:

function validateName() {
   return yesNoFormat(len(getName()));
}
function getName(str) {
   if (not validateName()) {
 variables.instance.name=retrieveNameFromDB();
   }
   return variables.instance.name;
}

getName calls validateName, and vice versa. of course this is much 
harder to debug when your cfc is doing a lot more.

Do you want to remove all spaces, or just leading and lagging.
If the latter you can use the trim(fieldname) function instead
of replace()

RE: "Proper Use" of Instance Variables

2005-01-03 Thread Dawson, Michael

One more quick question...

Should validate() return something (string, array, CFC, whatever)?

Or, should validate() return void and then require me to call
"hasErrors()"?

What is the norm, if there is one?

I guess if validate() returns an error-handler CFC, I can call its
hasErrors() method.  That would seem to be the best way to reuse code
throughout my app.

Thanks

You're using DataType as both a container and the elements it contains

You also aren't explaining what problem you're trying to solve with this.

Again, as with your singleton implementation, it seems unnecessarily complex.

But why are you validating on a *get* call??

Validation should occur either on a *set* or as a separate operation,

Re: "Proper Use" of Instance Variables

2005-01-03 Thread Barney Boisvert

I have validate() return boolean, and then have a separate
getValidationErrors() method that can be used to retrieve an array of
structs, one struct per error.  You could use an array of error CFCs,
but since errors are pure state, I don't see the real benefit of using
a CFC over just a struct.

With this usage, it would be more proper to name your validate()
method isValid() instead.

Thank God. A part of a thread I can actually contribute to...lol.


...do some stuff...








I like to return structs, and I try to add some error "stuff" in the
struct when I return it.

That's precisely why I like to try and use CF's built in TRY/CATCH
mechanism. I wasn't using it for the longest time, and then I just
jumped in and spent a weekend reading about error handling and stuff
like that, and I sort of fell into using it ALL the time. Less code I
have to write that Macromedia already took care of...lol

RE: Typesafe enum design pattern (another go)

2005-01-03 Thread Taco Fleur

Hey feedback!

> 3. Possibly... I seem to recall your solution was overly complex

OK, any ideas on how to make it less complex? 
Which part of it did you consider to be complex and why?
Some things that I did notice I could improve in the code is to use the
actual variable scope instead of evaluating a string in the
"getSingletonScope" method, and use some locking. 

> You're using DataType as both a container and the elements it contains
which seems wrong.

When I read up about the design pattern in Java this was the closest I could
get it to the real thing.
(link: http://www.javacamp.org/designPattern/enum.html )

> You also aren't explaining what problem you're trying to solve with this.

I was hoping to get some feedback from people that are familiar with the
design pattern, since I want to stick with the design pattern it would not
be relevant to explain what it should do, as that way I might receive
feedback on how to implement it some other way, but that is not what I am
after. I want to stick to the pattern, thus someone who is familiar with the
pattern could comment and provide feedback better than someone who does not
(also, I did specify that I could provide more details if required).

> Again, as with your singleton implementation, it seems unnecessarily
complex.

You must have had a close look at the code to make this assumption, please
provide details.

But as you said, maybe this is not the list to discuss this..

Thanks ;-)

Re: shopping cart, session variables - best practices

2005-01-03 Thread Donna French

The company I work for is currently still running on CF5 and I am in
the process of building my first custom shopping cart so thought it
would be appropriate to jump into this thread.

We are using CrystalTech for shared hosting, and the new site will be
running on CFMX and SQL 2000. From what I've read on this post the
best practice for my situation would be to use session variables and a
structure for the info on each item.

Any other tips for building a first shopping cart would be greatly
appreciated. Feel free to email me off list!

TIA,
Donna

Well, some design patterns are language specific and the problems they
solve don't always translate to other languages.

I think it's a mistake to focus on a design pattern in isolation of
how it should be used or, rather, what set of problems it is trying to
solve.

I just posted this in my Breeze room as an example of why code != pattern:

Examine the relative importance of sections in a pattern description
(from the GoF book):

FACTORY METHOD

Intent... (a paragraph)
Also Known As... (one name)
Motivation... (a full page!)
Applicability... (when to use it)
Structure... (one small diagram)
Participants... (a few bullets describing each class)
Collaborations... (one sentence)
Consequences... (almost TWO PAGES!)
Implementation... (describes several implementation options with a few
code fragments - three and a half pages - note that this is a set of
guidelines for implementation, not a *specific* implementation)
Sample Code... (just under two pages of simple code with commentary)
Known Uses... (half a page)
Related Patterns... (a few paragraphs)

The Motivation, Applicability and Consequences sections are the most important.

The (long) implementation section contains a lot of theory and suggestions.

Patterns are generally light on code and heavy on the whys and wherefores.

Example code alone does not teach a pattern!

Completely agree, which is why I did not provide an explanation, and was
hoping to get feedback from people familiar with the pattern.
The link was just to give an idea of what its all about, I actually read
about the pattern in another book. 

Anyway, I'll go and hide in my corner again and discover the world of design
patterns on my own again, I lost all hope to discuss some of this wonderful
stuff on the cf list and port the patterns to cf for all to enjoy ;-))

Re: Typesafe enum design pattern (another go)

2005-01-03 Thread Barney Boisvert

I think what Sean was trying to get at was that an implementation of a
design pattern in isolation of a problem it can solve is nothing more
than a bunch of arbitrary code.  If you have two problems that can
both be solved with the same pattern, and you use the same langauge to
implement each solution, the implementations will very likely be
different.  The design pattern itself is merely a guide as to how to
best approach implementing a solution.  If you go get a book on
patterns, you'll always find a problem description preceeding the
sample implementation, because without that context (the problem) the
implementation is meaningless.

That's pretty much all we can discuss unless you lay out the problem 
that you're trying to solve.

If you explain exactly what it is you're trying to do and why you're 
using the pattern it should be possible to say whether you're 
implementing it the right way.

I think that's the point Barney was making.

You can just stash the recordset in the application scope, much like
you would in CF.



or if you're not using JSTL

Re: Typesafe enum design pattern (another go)

2005-01-03 Thread Aaron DC

Sounds like Taco is reading and learning about patterns and trying to
implement / translate them into CF purely for the exercise or sake of doing
so. Hence he would like to discuss the implementation / code at a purely
theoretical point of view, rather than a specific implementation point of
view. Respondents to date seem to indicate that a pattern is basically
useless without the associated problem it was intended to solve being
present.

In a brain-storm session, Stage 1 is "every idea is good" - I think this is
the space Taco is occupying. Once all the ideas are written down, Stage 2
involves "picking the best / most doable" ideas - looks to me like this is
the space occupied by his respondents.

I think the pattern porting exercise would be interesting and potentially
valuable. This value could be greatly enhanced if a common CF or web-based
programming scenario was also invented, for which the pattern provides a
solution. Without this scenario, it would be like Mach-II or FB3/4 having
base code and documentation, but no example apps.

My gut feeling is that there are only a handful of other developers here who
would be able to discuss pattern templates or implementations. It may be
that another list is better suited, or a new "CF-patterns" / "CF-hardcore"
list would at least show you through its subscription how many others are
interested.

Good luck, Taco, I hope you find others that share your passion.

Aaron

That's not describing the problem. It's describing a solution.

Why do you need constants?

Why do you need them to be in a class/cfc?

Why do you not want the public to be able to modify any data and who do 
you define as the public?

Why do you need to be able to loop over the constants?

Re: Typesafe enum design pattern (another go)

2005-01-03 Thread Aaron DC

Could you use a struct? 

1. It's a built-in CF class
2. Public cant modify data unless you provide a mechanism for them to do so
3. Loop using any CF looping construct

2005-01-03 Thread Taco Fleur

I know what most of you are trying to get at (I read the book too) "Don't
use design patterns just for the sake of it".
I'm not interested in discussing that, a pattern solves certain problems,
lets just say I have all those problems that this particular pattern solves!

Aaron you are spot on. But as Sean already pointed out, this is not the list
to discuss it.
And yes a site dedicated to design patterns for CF would be nice (any
volunteers to help ? ;-)...

That's not describing the problem. It's describing a solution.

Why do you need constants?

Why do you need them to be in a class/cfc?

Why do you not want the public to be able to modify any data and who do you
define as the public?

Why do you need to be able to loop over the constants?

Well - that last question kinda of answered it.  With all users running the
code it DID crash the server.  ;^)

The initialization code, in this case, is actually pretty complex but more
importantly it would suffer data issues if run multiple times.  For example
it instantiates a session cache which is stowed in the application scope.

Since the current user's session is then stored in that cache it would be a
Bad Thing if the next request rebuilt the cache.

Sure, I could place 's around all the places that this would matter -
but it's much, much cleaner to just wrap the entire process in a lock.

Re: Typesafe enum design pattern (another go)

2005-01-03 Thread Spike

I think you could be spot on here Aaron.

There are several difficulties with implementing the typesafe enum 
pattern in CF exactly as it us usually seen in Java.

The first problem is that in the Java world the constructor is declared 
as private so you can't create an instance of the class. You can't do 
that in CF.

Second problem is that the variables are declared as static final, so 
you can't change them except in the constructor of the class that 
declares them. Again, you can't really do that in CF.

Also, in the Java world, a common use of the pattern is to ensure that 
the value passed as a parameter can contain only one of a set of 
pre-defined values. The common example given is a class called Suit that 
has 4 fields. One for each suit in a pack of cards. You can then know 
that when you declare the argument to a function as being of type Suit 
that it must be one of the 4 permitted suits and anything else will fail 
*at compile time* not at runtime.

That may or may not be a requirement for what Taco is doing, but if it 
was, it would affect the implementation in CF.

The other thing about enums is that there are so many ways you could 
possibly use them that it's very difficult to say whether an 
implementation is a good one without knowing more about the specific 
scenario.

Calling methods in the "constructor" area of a component could lead to
undesired results... As in the CFC being called from the URL as a
webservice.. Your main() would always fire off.. Just a heads up.

Re: "Proper Use" of Instance Variables

2005-01-03 Thread Brian Kotek

Back to the idea of using instance variables vs. using getter methods
within the CFC, keep in mind that if the getter method returns an
instance variable that is an array, you're getting a pass-by-value
copy of the array and not a reference to the original array. This can
lead to some bizarre things if you aren't aware of it, like trying to
modify the array returned by the getter but the actual instance
variable doesn't change.

cfmailpart problems

2005-01-03 Thread Marcus Whitworth

Hi,

I''m having issues with multipart emails using cfmailpart... 


#html_content#
#text_content#


This displays the html version fine with Outlook, but can
only display the text version with html-enabled email clients like Mozilla
Thunderbird, Safari etc.

However, if I just use the plain old cfmail with the type="html" attribute,
and NO cfmailpart tags, the above email clients can view the html just fine.

Suggestions?? Known bug??

Re: cfmailpart problems

It could be a setting in the mail client.  Most clients have a setting to 
display the preferred part of a multipart email - you could decide to display 
the text portion only in Outlook Express, for example.

No, I'm pretty sure thats not it. I am testing at the moment in Thunderbird, 
and other Multipart emails coming through are displaying as html just fine. I 
have also made sure that the email client is selected to display each message 
as html.

I'm assuming at the moment that CFmailpart just doesn't stick to the standards 
for multipart emails...

Well - that's a sordid, sordid tale full of highs and lows, villains and
heroes and a deeply fulfilling message that will leave your family closer
than ever.

Anyway... since you asked.

The site started getting high traffic late morning on the 29th.  It was,
however sucking up resources and causing all the other sites on the shared
host to slow down so our host (CrystalTech.com) turned it off.

The primary reason, then, for the slow down was that the available database
connections were getting overrun.  The site has a "planner" feature for
visitors that allows them to select events that they've like to go see.  As
built the planner saves selections to the database whenever it's updated.
With so many people using it the application was squeezing out other
applications on the server.

So I switched the app to only save plans for those (relatively few) people
that logged in and cut down on most of the my end-of-session logging (which
sped up the session manager from taking dozens of seconds every 20 minutes
to taking less than 200ms).

This improved the site performance a lot, but did mean we were losing data.
Ah well.

The traffic died down in the evening.  I did some more optimization.  I
cached static versions of all navigation, for example.  This meant that
pages could no longer present navigation consistent with security rules, but
on this site that's only used for administration so no big loss.

I also found a really dumb problem that (I'm nearly positive) caused serious
problems on server start under load.  See the thread called "Well - I feel
like an idiot" posted a few days ago for details on that.

Then I got a call the next morning (the 30th).  The traffic was back up,
much higher than before.  To protect the other customers CrystalTech shut of
the server again.  We attempted to throttle the connection, but that was as
good as having the site disabled (throttling meant that only about a tenth
of the requests were getting through, so even if you DID get the page you'd
miss most of the style sheets, graphics and scripts).

Finally around 2pm the client bit the bullet and let me order a dedicated
server.  CrystalTech graciously pushed our build to the top of the queue.
We went with the second option they offer: a P4 3.06GHz with 1 Gig of RAM
and a 120 Gig disk.

The server wasn't released until after 5pm and I went to work building it.
I had to install CFMX, stats, the site, etc.  One REALLY nice thing was that
I could still connect to the old database - that saved me more than a little
time.

Around 7pm I was done and we (myself and a couple of volunteers) ran through
a regression test.  We were done around 9pm and had some discussion about
how best to transfer traffic.

In the end we decided that a simple redirection on the old server was best
and quickest.  Traffic would originate at the old server and get immediately
located over to the raw IP address.  Not the best solution, but it beat
waiting for DNS updates to server we most likely couldn't afford to keep.

I turned back on all the logging, added some cache-management headers,
turned on "trusted cache" and attempted to tweak the simultaneous threads
and database threads.

I then went to bed (I'd had less than 6 hours sleep in the previous three
days).

However I SHOULD have remembered to install MX 6.1 updater.  That would come
back to bite me.

Anyway I didn't.  The new server ran very well - until about 11:45 when JRUN
pegged the CPU and froze up solid.  This is a pretty classic symptom of the
older database drivers in 6.1 and would have probably been solved by
installing the updater.

I ended up turning off the plan updates again in an attempt to get things
back on track (there was no time to install the updater then).

But I forgot.  Restarting the service got us back on track until about 2:30
when the same thing happened.  After that the server ran great for the rest
of the day (under much less traffic).  I feel pretty confident that had I
installed the updater the server could have quite happily handled the
traffic.

Also SmarterStats indexing service was running every 15 minutes which could
have contributed to the problems (I turned it off as soon as I noticed it).

The morning of the 1st traffic was back to nothing and I moved the site back
to the old server.  We'll most likely be canceling the dedicated server
until next year (but hopefully we'll get it EARLIER next year.)

After that I played lots of "Prince of Persia" and tried Half-Life
deathmatch for the first time (it was great!)  ;^)

No - didn't miss it - but I did ignore my real job all last week and didn't
get home today until after nine.  ;^)

I've posted a big long, self-indulgent reply - enjoy!

> Anything else you'd like to know?

Wow!  Great writeup!  

It's always interesting to me to know what types of challenges people
run into and how they overcome them.  I'm also very interested in how
well different sites (and people) handle load in real world
situations.  I've worked on some high volume sites and try to learn
new strategies whenever I can to prepare for the next time.

Interesting stuff, thanks again for the writeup!

As far as I know, it does.  If you'd like - you can send me an email and I'll 
look at it (just make sure to let me know if/when you do).

Yup and sort of conversely, if you return a struct remember that it is
by reference so if you do:

obj.getFoo().bar = 3;

you will overwrite the foo.bar inside the object.

Just stuff you need to think about with OO (not a CF issue really
since similar issues exist in Java, C++ etc). How encapsulated does
your object need to be in terms of what it hands out to 'client' code?

But that doesn't make sense - even in CF, there will be multiple
implementations of pretty much every design pattern and the choice of
implementation will depend on the exact problem you are trying to
solve.

But that makes no sense - a pattern is *not* an implementation
therefore there is nothing to translate. A pattern is a concept. Each
pattern has multiple implementations regardless of which language you
are using.

I think it completely misses the point of what patterns are about.

Not really - those are examples that use a framework, they are not
implementations of the framework. But then frameworks aren't patterns
either (since a framework is, by definition, code whereas a pattern
is, by definition, not code).
