Localizer/TranslationService question
by Pascal Peregrina 18 Sep '06

18 Sep '06

Hi, Does anyone know if Localizer requires iTools/iHotFix to work with Zope 2.8 if I only use MessageCatalogs (and not plain files) ? (I'm downloading the Products from here: http://www.ikaaro.org/download/index.html) Until now I was using the 1.0.1 version of Localizer. Thanks.

Zope at universities?
by Andreas R. Johnsen 18 Sep '06

18 Sep '06

Hei, I'm looking for information about the use of Zope at universities. Most large universities have a very heterogeneous infrastructure and I guess many of them utilize Zope in a way or another. I'm looking for references to universities where Zope is part of a central strategi or in other ways plays an important role for several of the web sites at the university. Two examples are ETH Zürich and University of Bristol. More examples? Regards, Andreas

Foreground, but not debug.
by Richard Downing 17 Sep '06

17 Sep '06

Is there a way to run zope in the foreground, but not in debug mode? Debug means that it runs very slowly, and I want to run it under the control of a supervisor (runit). zopectrl -fg doesn't seem to recognise the zope.conf setting. I'm new to zope, but it seems to do what I require. Thanks in advance. R.

Problem generating Transfer-Encoding: chunked
by Norbert Marrale 16 Sep '06

16 Sep '06

Hi All, I'm in the process of writing a python script that goes through a long list in batches and outputs its progress to HTML. (Zope 2.7.5 behind Apache) The result is not what I expected: instead of returning the results in small chunks, Zope (Apache, gremlins?) rewrites the output and returns much larger sections of data. If I remove the Transfer-Encoding header and replace it with a fixed Content-Length, I can see that my script outputs its chunks as intended... Can anyone offer suggestions? Norbert [Code below:] RESPONSE=context.REQUEST.RESPONSE RESPONSE.setHeader('Content-Type', 'text/html') RESPONSE.setHeader('Transfer-Encoding', 'chunked') RESPONSE.write( str(hex(len(htmlHeader)))[2:]+'\n'+htmlHeader+'\n' ) def doBatch(start, end): -- run through list and output -- RESPONSE.write(str(hex(len(htmlContent)))[2:]+'\n'+htmlContent+'\n') while myBatch <= numBatches and start <> -1: start = doBatch(start,end) end = start + batchSize myBatch +=1 RESPONSE.write(str(hex(len(htmlFooter)))[2:]+'\n'+htmlFooter+'\n\n') [incorrect HTML output snippet:] HTTP/1.1 200 OK Date: Fri, 15 Sep 2006 22:37:22 GMT Server: Zope/(Zope 2.7.5-final, python 2.3.5, freebsd4) ZServer/1.1 Content-Type: text/html X-Cache: MISS from xxx.xxx.xxx Keep-Alive: timeout=15, max=99 Connection: Keep-Alive Transfer-Encoding: chunked db8 <html> <head> <title>Progress Report...</title> </head> <body> <h2>Batch 0: 0 - 25</h2> <-- expected new chunk <p>[data]</p> <h2>Batch 1: 26 - 51</h2> <-- expected new chunk <p>[data]</p> <h2>Batch 2: 51 - 76</h2> <-- expected new chunk <p>[data]</p> 45e <h2>Batch 3: 76 - 101</h2> <-- why does chunk start here? <p>[data]</p> <hr> <-- expected new chunk <h2>DONE!</h2> </body> </html> 0

No, I don't.

I am *guessing* that it looks like <dtml-var text html_quote> or <dtml-var text html_quote=1>. Remove the html_quote attribute and you should be OK. But since you say this used to work in zope 2.7, there is probably some other problem. It's hard to say without having access to more of your code. Sorry. -PW -- Paul Winkler http://www.slinkp.com

Turning off authentication for a zpt page
by Sinang, Danny 15 Sep '06

15 Sep '06

Hello, I'm using a Zope product called OpenFlowEditor and I modified one of its .zpt pages (view_process.zpt). All is well, except that I now want to allow Anonymous users to view this zpt page. I tried doing so by checking the "Anonymous" checkbox for the "View" privilege in http://myserver/OpenFlowEditor/view_process/manage_access , but still no success. Am still being asked for a username and password. Any idea on how to get this working ? Regards, Danny

upgrade from 2.7.5 to 2.8.6
by Miles Waller 15 Sep '06

15 Sep '06

Hi, I have just upgraded the staging/test version of a large site from 2.7.5 to 2.8.6. When restarting zeo, it seemed to take a 'long' (in the most subjective sense) time to come up, and I noticed this entry in the logs: 2006-09-14T17:36:23 WARNING ZODB.FileStorage Failed to load database index: exceptions.AttributeError: type object 'BTrees._fsBTree.fsBTree' has no attribute '__basicnew__' Does anyone know what this means? Is it important/indicative of any sort of problem at all that I should be aware of? Does the storage do anything in response to this at all? When the live version is upgraded, downtime has to be at a minimum, or I will get phonecalls ... Thanks, Miles

Remove/Ignore <P> and other HTML tags
by Zhi-Wei Lu 15 Sep '06

15 Sep '06

I am a system administrator who maintains our Zope servers. I don't know that much about python or zope, just enough to upgrade and trouble shooting from time to time. Of course, the developers who have developed the system are no longer here. I try to move a site from Zope 2.7.4 (python 2.4) to a new server with Zope 2.9.4 (python 2.4.3), after some struggle, I have fixed most of the problems, but one that I don't have much clue. I hope that expert here can shed some light for me. Here are section of code that displays part the of some abstract <dtml-let rand1="get_random_image()" cap1="get_folder_title(name=rand1)" text="get_abstract_sample(name=rand1)"> <table cellpadding=0 cellspacing=0><tr> The function get_abstract_sample is here for object in container.research.objectValues(): a = object.getId() if (a == name): text = object.research_description_html.read() else: pass text = str(text) return text[0:400] + '...' The above code work fine for the 2.7.4 server, but fails for 2.9.4 server, it will ask for authentication password for 2.9.4, no user/password combination will work. If I modify it as follows (for 2.9.4 server) for object in container.research.objectValues(): a = object.getId() if (a == name): text = object.research_description_html text = str(text) return text[0:400] + '...' Getting rid of read() for the 2.9.4 server solve the authentication problem and display the web page but with some unpleasant <P> and other HTML tags literally (It doesn't for the old 2.7.4 server). I would love to hear suggestions and advices from this group to get rid of the literal <P> and other HTML tags. Thank you very much for your help. Thank you very much for your attention.

Re: ZEO with Multiple Storages

Just to clarify, you are saying that a single ZEO server would not be able to deal with multiple storages simultaneously and that a transaction in one storage would block transactions in all other storages. However, if we were to run multiple ZEO processes this would not be the case? -Brian

Will Zope Run On Iron Python In Mono?
by Mark, Jonathan (Integic) 15 Sep '06

15 Sep '06

Thanks to everyone who offered advice on how and whether to examine the ZODB objects that Squishdot uses. I now have a better understanding of the unique role that ZODB object storage plays in Zope, and why replacing ZODB with RDB/SQL is not in general warranted. I isolated the Squishdot performance problem as being in a single <dtlm-in> command and will raise the matter further on the Squishdot mailing list. Mono intends to support Iron Python. Are there plans for Zope to support an Iron Python/Mono configuration, without use of CPython?
