Version 3.0 Beta Test FeedBack

Hi Everyone,

I'll be sending coupons to everyone that did beta testing so that you can download the new version for free.  I just need to figure out how to get them to work in the store.
This will allow you to be setup in the system for future services and will make it easier for me then having to do individual e-mails with license keys.

NFX,

That is something more to go on at least.  I think what I need to do is send you a debug version so we can tell exactly what stringbuilder is causing that OOM error.

John I have found an interesting "feature" of PB 3.1.5 that is causing me dificulty.  I have PB installed on my primary site www.Agingsafely.com, but not on it 30+ parent portals.  I figures out a way that I could use it on them to make them much more SEO-friendly and also save me lots of typing when setuping up new ones.  I wanted to use  "our"  ReplaceDescription  and ReplaceTitle rules and create a similar one that would use ListX to taylor a block of text and replace a placeholder in the Text/HTMl module on the same page.

I placed PB at the bottom pf the page, activated "load saved rules" and to my surprise I don't get MY saved rules I get your default saved rules.  Now I need an easy way to move the required rules from the default portal to 30+ other portals.  I assume that you had a good reason to make the save rules unique per portal.  I suppose that I could put these tree rules in the "global rules" where they would get executed on all sorts of pages where they aren't required -- Kind of Yukky.

I thougt that you were thinking a an import/export method. Did you ever do anything on that?

PS: I still can't order PB 3.1.6

Hi Dave,
PageBlaster gets installed at the DNN host level, so it should be available to all portals. Maybe you are just saying that you have not used it on any portals other than the default yet.

The Saved Rules are unique per portal because administrators of different portals may not know each other.

To copy SavedRules from one portal to another you can go to the DesktopModule/Snapsis/PageBlaster/Config/SavedRules folder and copy the file , and rename it to have the new portal number PageBlaster.SavedRules[ 0 ].config --> PageBlaster.SavedRules[ 1 ].config --> PageBlaster.SavedRules[ 2 ].config (spaces added in the brackets to make it show in the forum)

You can also do this with the PortalRules if you want to save a step in copying them into the PortalRules.

When you put your coupon in for 3.1.6, add the module to the cart first, then add the coupon on the cart page. I guess the Cart price rules for Catalook do not work if you add then from the Product Page.

Hi john,

thank you for your e-mail and the offer of  free pageblaster. But my promo code didn´t work as you describe in your e-mail. I got an error with info that my promo code is wrong :(.

thanks jens

I figured out the problem with the coupons.    If you try adding the coupon at the time you select the product it does not recognize it.    What you have to do is to just add the product without the coupon and then when you get to the checkout you then add the coupon and it works.

hi john,

yes it works. Was my fault, because i add the promo code on site before i do add to cart. On this page altough a field for promo code :)

No all is fine.

Thanks Jens

I'm ready to run a debug version whenever you send it. I really want to get in on the PB3 goodness soon, but I can't until we figure out the memory leak.

Hi NFX,

Sorry I got sidetracked and forgot about this one.

I have attached a debug version to this post, if you place the DLL & PDB file in your /bin we should see more information in the error.

John,

I've been running this since last night and so far no major problems! CPU usage is also down from what it was before and memory only increased a max of about 10MB (probably due to the debug mode and I turned on full debug in the trace). But the site has been running fine and dandy is the attached debug build the same version as release?

EDIT: It looks like there was an OOM exception late last night at about 1AM but the logging did not seem to catch it. Where should I look for the extended info?

UPDATE: Here is the debug log of the OOM:

NOTE: the only replacements that should be happening on that page are two load file replacements that happen site wide to put in my google analytics code BUT I have a rule that should be exluding this specific page (http://www.warbeats.com/Default.aspx?tabid=57)   path pattern="tabid[/|=]⏅|58|36|86|91][/]" excludeFrom="All"

Is there anywhere I can see which replacement it was trying to process?

I have a feeling that it is the downloading of files that is causing the OOM error.  This is a common problem on web servers because each file that is uploaded or downloaded has to be completely put into memory when doing it through http.

Notice how the debug file also has an OOM error on the next operation which is doing compression.

You were reading my mind on trying to find out which rule was being processed though. I just added that information into the debug message in the attached file.

How big are your download files?  You may want to consider hosting your downloads on a CDN like Amazon S3.
