fastcgi mangles images
by John Edstrom 14 Jan '00

14 Jan '00

I'm trying to set up a Zope site to be accessible through an Apache server via fastcgi. The suggested procedures in the how-tos seems to work. Except! the pages displayed on the browser are badly distorted. The effect is variable, but I get things like missing background tiles, blocks of black color, i.e. general weirdness. The page looks fine when displayed through ZServer directly. I've checked the HTML & text and what gets through is fine. I use a jpeg as a background tile and some images here and there. If I take out all images from the document then the page looks fine through fastcgi. If I include just the background tile image from the fastcgi/ZServer, the whole page is displayed weirdly. If I take the exact same image from the apache server the page looks good through fastcgi. I'm thinking that the images are getting munged somehow and confusing the browser. I'm using a DEC UNIX machine (I don't have a problem on intel Linux). I wonder if there is a problem somewhere with how FCGIServer.py handles images (and possibly other blocks of binary data). Looking in FCGIServer.py I see things like: self.contentLength = (vals[4] << 8) + vals[5] I don't know python internals at all. Might this sort of quick calculation by shifts generate erroneous transfers on 64-bit machines? -- John Edstrom

RE:Catalog bug ZClass constructor
by Jason Spisak 14 Jan '00

14 Jan '00

Brian, Here is the code I have for the ZClass is was building when I found this out. Does any of this look like "custom code" that would account for a leading slash? <dtml-comment> Set a REQUEST object called 'id' as a unique number by representing the current time as an integer, and then convert that to a string. </dtml-comment> <dtml-call "REQUEST.set('id', _.str(_.int(ZopeTime())))"> <dtml-comment> Create an instance of the CompanyClass with the 'id' we just set in the REQUEST. </dtml-comment> <dtml-with "CompanyClass.createInObjectManager(REQUEST['id'], REQUEST)"> <dtml-comment> Pack all of our for values and anything else in the REQUEST into the proerties of the CompanyClass instance we just created. </dtml-comment> <dtml-call "propertysheets.Company_properties.manage_editProperties(REQUEST)"> <dtml-comment> Because the 'CreateInObjectManager' we called above indexes the object before we called 'manage_editProperties', all of the properties of our new Company are blank as far as the Catalog is concerned. Not Good! So we tell the Ctalog to take another look, now that they have values. </dtml-comment> <dtml-call reindex_object> </dtml-with> <dtml-comment> Okay, now that we've created a Company, let's be nice and send the user into it. We do this by redirecting the browser to a page inside our new object. The URL2 tells us to chop off the last 'two' elements of the current URL and the the '+' adds on the id of the object we just created. So they end up inside the new Company! </dtml-comment> <dtml-call "RESPONSE.redirect( URL2 + '/' + REQUEST['id'] )"> This is very basic stuff, so I was suprized to see a problem. I am calling something in a nold way that doesn't need to be? Please let me know. -- Jason Spisak webmaster(a)hiretechs.com

Is there any custom code around this logic?). BTW, absolute_url did change to support virtual hosting in 2.x. This could be causing a problem in your ZClass constructors. Jason, try inspecting the return value of absolute_url in your constructors, you may have to prepend a / -Michel

Making documentation easier
by Chuck Burdick (TT) 14 Jan '00

14 Jan '00

I'm working on some documentation for ZFormulator, and I'm running into various issues trying to cleanly present DTML examples. The problem is that it seems that Zope ALWAYS interprets dtml tags unless you use HTML entities (like < and > instead of <, >) to surround your tags. This happens in <pre>...</pre> HTML tags or as example code in structured-text. However, using HTML like this defeats much of the convenience of documenting in structured-text. Is there a way to stop Zope from interpreting the tags? Alternatively, how difficult would it be to create a <dtml-suppress>...</dtml-suppress> tag to suppress tag interpretation? Imagine the following as structured-text: ====BEGIN==== Example1 - Won't work because Zope interprets tags:: <dtml-in myexample> <dtml-var title> </dtml-in> Example2 - Hacked to make code appear as code: <pre> <dtml-in myexample> <dtml-var title> </dtml-in> </pre> ====END==== Notice that example1 tries to use the example code symbology of structured-text and that example2 "cheats" by embedding HTML into the structured-text.

Very important for CatalogWare zopists
by Jason Spisak 14 Jan '00

14 Jan '00

Zopists, I have submitted this to the Collector and it is major for people who have items in their ZODB that are Catalog aware. To create the bug follow these steps: 1.Create a Catalog Aware ZClass 2.Create an instance of that class 3.Make sure it is indexed by looking in the Catalog "Catolaged items" tab 4.Notice that there is *no* slash in front of the indexed url: "MyFolder/myobject" 5.Now clear the Catalog 6.Go to the "Find Items to Catalog" 7.Select just your New ZClass meta type so it is quick 8.Click "Find" 9.Make sure it is indexed by looking in the Catalog "Catolaged items" tab 10. Oh no! It has a different url. A leading slash! "/MyFolder/myobject" 11. Click on the link. It's broken! What this means is that if you have a lot of items in you Catalog don't ever ever ever use the "Find" machinery until Digital fixes this(It worked in 2.0.0 Final). You will end up not being able to edit/reindex your objects, and the links in your applications may not function. I am looking for how "Find" and index_object in createInObjectManager are different. No luck yet. All my best, -- Jason Spisak webmaster(a)hiretechs.com

Re: Zope-Dev digest, Vol 1 #351 - 1 msg
by Jason Spisak 14 Jan '00

Brian, I use the default constructor given to me by creation of a ZClass. To make it realistic, I have a propertysheet that has a few properties in it. When you createInObjectManager, the Catalog gets called, soyou have to call reindex_object again to get the propertysheet to be in the Catalog. And then I redirect. There's not absolute_url call, and it's getting indexed from where it is in the ZODB tree. (no acquisition) Have you followed those steps with a fresh Zope? It doesn't give you two different Catloged urls? Jason Spisak

RE: [Zope-dev] Factory pollution, scopes, zope hosting

> I already described a problem of ``factory pollution'' I'm > facing ...... I was going to settle for deleting the > Factories and making some scripts to add all instances > programatically This change will have some other undesirable (and possibly unexpected) consequences. If the user can not create the object using ObjectManager, then he can not paste them or import them either. This actually leads to further 'factory pollution'. Many of my objects are copy/pasteable but not manually createable. I have to create a dummy factory (with a bogus entry on the list) to pacify ObjectManager.
