Authorization failure

Hi there ! I found a strange behaviour in Zope yesterday. I have the following contruction in an HTML - Object : <dtml-if "feldname == 'Freikonto'"> <dtml-call "REQUEST.set('freikonto', feldwert)"> <dtml-elif "feldname == 'Konto'"> <dtml-call "REQUEST.set('konto', feldwert)"> </dtml-if> Now the "feldname == 'Freikonto'" clause isn't necessary anymore. So I thought I just comment this section. The result would look like this: <dtml-comment> <dtml-if "feldname == 'Freikonto'"> <dtml-call "REQUEST.set('freikonto', feldwert)"> </dtml-comment> <dtml-if "feldname == 'Konto'"> <dtml-call "REQUEST.set('konto', feldwert)"> </dtml-if> If I try to save these changes, Zope complains, that I'm not authorized although I'm superuser and have all rights. But if I delete this lines instead commenting them, it works. Really strange. Any ideas ? Thanks.

Thanks. > Hm, I believe, you have to close the <dtml-if> block even if it's in a <dtml-comment>. It shouldn't but it does, this was discussed recently on the list. THe unauthorized sometimes comes up when a dtml method is in fault. THis is also strange, but a fact of life ;-). THis added up accounts for your strange behaviour Rik

Structure text
by Sin Hang Kin 13 Mar '00

13 Mar '00

there are a few of howtos in Zope which use structure text were broken. I dont remember all of them, but the one with date and sql is (I still can not read it). BTW, I think structure text should be not be used in current way. I think a good use of structure text is to use it convert from/to. Instead of publish. A greate tool but in bad use. Rgs, Kent Sin.

Re: [Zope] Catch error
by Sin Hang Kin 13 Mar '00

No. I mean that setting a production flag on the zope server and let all error messages goes silent. It will be very difficult and troublesome to keep track of all errors. Just because some one have make a rename on one of my object, or the object is being modify and thus not available. Also, are there anyway to remove all the manage things from a production site?

Hi, Id be willing to contribute to the coding effort. One of the features I was considering was a new DTML syntax that used XPath to reference objects: <dtml-with "obj1//obj2@propname"> The text in quotes is XPath notation.

frexp error
by R. David Murray 13 Mar '00

13 Mar '00

OK, I just tried to add a new metadata field to that 53K item catalog I have. I got the frexp error I mentioned in an earlier post but did not have the actual traceback for. So here's the traceback in case anyone can do anything with it. I assumed that when I added a metadata field nothing would happen until I reindexed objects that had that field. Am I wrong, does ZCatalog automatically update the catalog when a metadata field is added? Here's the traceback (paths elided for clarity): Error Type: SystemError Error Value: frexp() result out of range Traceback (innermost last): File ...Zope-2.1.2-src/lib/python/ZPublisher/Publish.py, line 214, in publish_module File ...Zope-2.1.2-src/lib/python/ZPublisher/Publish.py, line 179, in publish File ...Zope-2.1.2-src/lib/python/Zope/__init__.py, line 202, in zpublisher_exception_hook (Object: ElementWithAttributes) File ...Zope-2.1.2-src/lib/python/ZPublisher/Publish.py, line 169, in publish File ...Zope-2.1.2-src/lib/python/ZODB/Transaction.py, line 237, in commit File ...Zope-2.1.2-src/lib/python/ZODB/Connection.py, line 325, in commit (Info: (('BTree', 'Bucket'), '\000\000\000\000\000\002\027]', '')) SystemError: (see above) By the way I had the stupid file logger running and it didn't show anything when this error occured. Also, grepping the source I see an error message with the above text in cPickle. This is running on BSDI 4.1. Am I running into a BSDI bug here? --RDM

Python Method infinite loop?
by Jeff K. Hoffman 13 Mar '00

13 Mar '00

Hello, One of my developers just wrote a Python Method containing: while 1: print "Foo." and it happily rendered, tying up that thread indefinitely. Is this supposed to succeed? I thought Python Methods were "safe"? I am using Zope from CVS (I updated yesterday.) This is not a problem for us, really, as my guys don't generally write infinite loops (unless it's on purpose. :-)) However, I thought I would point it out in case it's a bug. --Jeff --- Jeff K.

asynch I/O in external method question
by Sam Gendler 13 Mar '00

13 Mar '00

Is there a way to hook into the asynchronous machinery of Zope/Zserver from within an external method. I have to process credit cards over a modem, which takes approximately 10 seconds per transaction, during which, whatever thread is executing the external method is blocked, waiting for a response from the credit card server. I suppose that this means that as soon as I have 7 credit cards being processed simultaneously, my Zope is going to stop responding. If I had a way to hook into the asynch machinery of zope, that thread could happily be servicing other requests while it waits. Is this possible? --sam -- -------------------------- Sam Gendler CTO, Impossible, Inc. 1222 State St. Suite 250 Santa Barbara, CA. 93101 p: 805-560-0508 f: 805-560-0608 c: 805-689-1191 e: sgendler(a)impossible.com
