RE: iif: am I understanding correctly?
I've seen debates around this so many times I decided to blog it: http://blogs.sanmathi.org/ashwin/2006/07/24/whento-evaluate-and-iif/ In summary - evaluate() and iif() will perform well when the expressions being evaluated remain static, since the Java classes that are compiled to process the expressions are cached in memory. If the expressions change from call to call (different sets of operators and variables), then these will be expensive, since the expressions will have to be compiled into Java classes for every call. -Original Message- From: Snake [mailto:[EMAIL PROTECTED] Sent: Monday, July 24, 2006 2:18 PM To: CF-Talk Subject: RE: iif: am I understanding correctly?

RE: What determines session inactivity timeouts?
Hey Reed, Try replacing your test.cfm with this: cfobject type=JAVA name=obj class=java.lang.Thread action=CREATE cfdump var=#session# cfset session.x=1 cfdump var=#session# cfoutput#timeformat(now(),HH:MM:SS)#/cfoutput cfset obj.sleep(7) BRBR cfoutput#timeformat(now(),HH:MM:SS)#/cfoutput cfdump var=#session#br cfoutputx=#session.x#/cfoutputbr cfset session.x=2br cfoutputx=#session.x#/cfoutputbr You can set values to the session even after it's expired (with one exception, see below), but these will hold only for the execution of the current page - touching a session after it's expired will not bring it back to life, sorry, no night of the living dead sessions (apologies all, I couldn't quite resist that)! The exception to the rule - if Use J2EE session variables is off on your administrator, execution will proceed with no problems. However, if it's on, an exception will be thrown trying to set session.x after the session has timed out. This is because the reference to the the session object maintained by CF has been cleared from the associated J2EE session. Ashwin -Original Message- From: [EMAIL PROTECTED] [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Wednesday, April 26, 2006 11:06 PM To: CF-Talk Subject: Re: What determines session inactivity timeouts? OK, I did what I should have done before starting this thread, which was to rig up a test case to see what happens. Pretty interesting results. It appears that CF keeps the session vars alive during page processing, even if there is no activity with those vars. Here is what I did: In Application.cfm: cfapplication name=test clientmanagement=no sessionmanagement=yes setclientcookies=yes setdomaincookies=yes sessiontimeout=#createtimespan(0,0,1,0)# applicationtimeout=#createtimespan(0,1,0,0)# loginstorage=session In Test.cfm: cfobject type=JAVA name=obj class=java.lang.Thread action=CREATE cfdump var=#session# cfset session.x=1 cfdump var=#session# #timeformat(now(),HH:MM:SS)# cfset obj.sleep(7) BRBR #timeformat(now(),HH:MM:SS)# cfdump var=#session# HERE IS WHAT HAPPENED: First time I executed test.cfm, I got three CFDUMPS of the session scope: dump 1 had no vars in it, dumps 2 and 3 showed the var I set in my code. Since there was a 70 second pause between 2 and 3, and the session var timeout was set to 1 minute, that tells me that CF kept the session vars alive. I waited 2-3 minutes and reran, with the same output - which shows that CF did in fact destroy the session vars after the 60 second timeout occured between the two page requests. Then I ran another variation: I ran the script again, and then when it finished I reran it immediately, and guess what - the session var was gone! That makes it look like CF kept the session var alive during the script's execution, even though the timeout was reached, but deferred destroying the var until the request completed. So I did another scenario: ran the same test in 1 browser, but with the pause set to 2 minutes, and immediately in another browser window ran a script that simply did 2 CFDUMPs of the session scope with a 60 second pause between them. The second window (which began and ended during the first window's 2 minute pause period), showed the session var to be alive on both dumps. I refreshed it's screen immediately, and when it finished the session var was gone. This tells me that when CF deferred destroying the session var during the first script's execution, it kept the var alive for all other requests, not just for the currently executing one. Final test - I changed the second script's pause to be 2 minutes, and waited about 10 seconds after running the first script before starting the second, to see what happens to the session vars for the second script when it it still running after the first script ends. The session vars for the second script were still there on both dumps, which is pretty interesting because it said that when CF saw that the second script was running it kept the session vars alive, even though it never touched any of them. But the immediate rerun of the second script showed that the vars were gone as soon as it had finished. Bottom line is that session vars don't dissapear out from under you during script execution, but when the lifeguard blows the whistle the session vars are gone as soon as the last guy is out of the pool - unless someone new jumps into the pool and actually touches a session var. Whew Reed It is possible that the delay could occur while processing a single CF tag, therefore, you would have no way of touching a session variable. For example, the session timeout is 5 minutes. On the page, you have a CFFILE tag that save a huge amount of data to a text file. It could take 7 minutes to save the file. By the time the CFFILE tag completes, the session has expired. There is no way to hook into the CFFILE tag and have it restart the session
RE: Get String Byte Size
Try this: http://martin.nobilitas.com/java/sizeof.html The empirical formula derived there indicates that string memory is 38+/-2 + 2*(string length) bytes. In my own tests on JDK 1.4.2_09 I got something similar: 40 + 2*(string length) bytes when length2. For length 0 to 2, the size works out to just 40 bytes. That said, as Nick mentions, if all that you're trying to do is get an idea of the relative memory occupied by different strings, rather than the actual physical memory (which, as discussed in the link above, can be determined only empirically, not precisely), you might be best off just checking the length. -Original Message- From: Nick de Voil [mailto:[EMAIL PROTECTED] Sent: Wednesday, April 19, 2006 9:47 PM To: CF-Talk Subject: Re: Get String Byte Size Anyone have any quick code to retrieve the number of bytes in a string /without/ writing the string to a file first? I'm trying to do a little debugging and I'd like to know the size of a string that is being returned to the browser. The number of bytes occupied in the application's memory by the Java String object is probably not the same as the number of bytes occupied by the same string in the HTTP response. I could be wrong on some points below but I'm sure others will correct me if so (Paul?) As I understand it, a Java program such as CF always stores characters internally using UCS-2 encoding, i.e. 2 bytes per character. In addition, the String object will include 20 or 30 extra bytes for storing the length of the string etc. I believe that CF's default behaviour is to encode HTTP responses using UTF-8 encoding, i.e. 1 byte per character if you're only using ASCII characters, and of course the extra bytes used by the String object won't be there either. So let's say your string is Rob. - In CF the Len() function gives you 3. - The size of the Java object - even if you could work it out, which is next to impossible in Java - would be 6 + the extra bytes, maybe 40 or more. - But in the HTTP response it would probably be 3. So, if I've understood your question correctly and it's the HTTP response you're interested in, just using Len() in CF will give you the best answer.
