Re: [Zope] Beginners Confusion
Hi Russell, Russell Winter wrote: Thanks for the prompt response, the reason behind keeping the users separate is that each team wants to feel that they have some control over their destiny's and we are happy to pander to this thought, they also each have a completely different set of visitors to the sites and wish to keep their sites separate. From our perspective, we also want to have that little more control over each team but in the way of resources but allow them some flexibility in their choices. Fair Enough. However, I had worked out that instances seemed to be the way to go, but I confused myself more by trying to setup and instance for a test user and failing dismally, the instance error'd in a number of ways, mostly I figured to do with permissions. This will just take time to work through I think. Yup, but it is the way to go... cheers, Chris -- Simplistix - Content Management, Zope Python Consulting - http://www.simplistix.co.uk ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

You don't actually have to do this. 2) in the wrapper class, use ClassSecurityInfo() to declare the methods you need public or permission-protected, or use allowAny(). You can apply these, and module security declarations, from any piece of trusted code, to any other piece of FS-based code. You know, some days I wonder why it is that Zope is the only framework around that needs to distinguish between trusted and untrusted code. Nobody else seems to be looking at us with envy in this regard. Well, while I'd like to agree with you, I like having semi-trusted code, but I think Zope 3 does a much better job of this... cheers, Chris -- Simplistix - Content Management, Zope Python Consulting - http://www.simplistix.co.uk ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

Something like: from BTrees.IIBTree import * t = IIBTree() t.update(context.select_from_LOCATION_MATCH) # errr, no 2. How do I find the matching node i.e. when I want to know that 6422 relates to location_id 15? Any help or pointers to further documentation would be appreciated.

Re: [Zope] add multiple images to zope folder
I once started down that path with FTP. I use HomeSite, as well, to save via FTP. I investigated a Linux package called Delegate, that would provide a rev-proxy for FTP over SSL, in which normal FTP clients with SSL could transfer files. www.delegate.org I didn't continue, priorities and all.

[Zope] Adding TextIndexNG 3.1.1 error
Zope 2.8.0

RHEL 3
I installed TextIndexNG 3.1.1 and associated extension_modules without
a problem. Trying to add a TextIndexNG index to my catalog returns:

I'm pretty sure I followed all instructions and I've installed and
used previous versions of TextIndexNG without a problem on other
instances of Zope 2.8.x.
Can anyone help figure out what's going wrong? Traceback follows...

Re: [Zope] FOLLOWUP: 120MB file import failures
Hello, I found the source of my problem uploading a large file to ZODB over DAV and an a workaround that shouldn't have worked but worked. For those who are interested: For completeness: I would like to put a 120MB file into ZODB and it is constantly failing. But you should have learned that you cannot simply say is failing but must describe precisely (error information, traceback) *how* it is failing... Correct Dieter, I was vague but it indeed would progress and then fail. Goliath, a mac web dav client, would report Unknown connection error and the Finder would report ... cannot be completed... one or more required items not found (error code -43) I apologize that I am not familiar with Zope's traceback. Thank you to Tino for providing a script to copy files into ZODB. This solves a few other issues. So. I knew to watch my /tmp directory and it was not being used. It turns out that Python (presumably, not Zope) was using /var/tmp (over RAM, given that large-file-threshold in zope.conf was lower than 120MB). I linked /var/tmp to /tmp and oddly it started using /usr/??? but at least it worked because there was more than 120MB available there. I am not quite sure where it ended up putting it. (seemingly not /var in the zope instance) The solution appears to be that python can use the TMPDIR variable to specify where tmp should default to (reportedly it will try various locations) but, I am not clear how I can add this to Zope's rc script to declare it. I tried it as simply setting the environment variable set TMPDIR=/tmp but that gave warnings about the startup logic. 1. Should TMPDIR work? 2. Where should I declare it when using rc scripts? 3. Any chance zope.conf can use it?

[Zope] Translating a webpage
I'm wondering if someone can point me in the direction of some documentation that will tell me the best way to translate a web page into multiple languages using Zope Page Templates. In previous sites we've done in DTML we used a 'phrases' table in our MySQL database that contained phrases in each language the site required. We then used sql methods and a dtml-let statement to create a list of the phrases used on a certain page. I'm considering using the same basic idea for a page template site, but am wondering if there is a better way of doing translations. I've read about using .po files. Is there an easy way to hook these up to Zope? Any help would be greatly appreciated.

Re: [Zope] Finding a match in a large dataset - btrees?
Thanks for the many replies. I apologise for the original message which was obviously very unclear - I will try to correct that. Basically I want to match a telephone number to a rate table.

Perhaps the best way is to write a procedure in MySQL however I am interested in any python-based alternatives. Your problem is more an algorithmic problem than q question of the data representation. Store the mapping as some BTree (possibly IIBTree using normalized integers for the values). Then you have to iterate over all prefixes of the dialed number starting with the longest prefix to the smallest prefix. Then perform a lookup of the prefix in your BTree... this is should not take more than five lines of code and requires a maximum of #(length_of_dialed_number) comparisons. If you want it more complicated construct a tree and you'll have a logarithmic number of comparisons. I doubt that it is worth the effort since the first solution should be fast enough unless your dialed number is hundreds of digits long :-) -aj pgp2ARghXrI2q.pgp Description: PGP signature ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

[Zope] Re: oddity with zope and webdav
On Mon, 05 Dec 2005 18:17:38 -0700, David Bear wrote: I have a zope instance listening on localhost. I use apache and fastcgi to reach zope. Now I would like to provide webdav. Since my apache is already doing ssl, I wanted webdav connections to also go through apache. when I use cadaver and connect to my zope zope through apache, all works well even though I have specified in my zope.conf file that webdav listen on localhost:8088 (it seems that cadaver is smart enough working through the fastcgi interface to just work). When attempting to using dreamweaver mx or windows webfolders to connect to zope I get an error. So I attempted to use an apache proxy pass directive to campture all urls at myzopeserver.edu:8088/webdav back to localhost:8088. This had no effect. cadaver was still able to work. Dreamweaver (using webdav site setup) and windows webfolders still failed. What deep magic do I need to make dav work through apache? ( would prefer to have all things go through fastcgi but I understand the trend is to use proxy-pass ) I believe this patch is required if using recent WinXP, due to Microsoft webdav breakages: http://teyc.editthispage.com/2005/06/02 It fixed webdav for web folder for me.

Re: [Zope-dev] Logging of ConflictError
Dennis Allison wrote: Dieter's point about not includeing the traceback makes sense if all it does is report on the reporting code. Yeah, the traceback just shows where the ConflictError was raised, not what caused it, and theyr'e always in very different places... Wlorent, do you envision a single ConflicError or two -- one which succeeds on retry and another where the retry fails? Huh? ConflictErrors are ConflictErrors, it's a server level decision as to how they're handled. Zope chooses to retry the whole request up to 3 times when a ConflictError occurs. The new logging code I put in records exactly how many conflicts have occurrred, and how many remain unresolved even after 3 retries.

As I said, I'm not crazy about this, it seems needlessly fragile and makes the test code harder to read than I'd like. So I'm inclined to follow Tres' adapter suggestion, it seems like The Right Thing to me. I'll modify the existing suite accordingly on a branch. To the other respondents: Thanks for the suggestions, but I do not consider making AcceleratedHTTPCacheManager more flexible to be a test turd. Tres outlined a real use case for changing the code (see below). I don't understand why you guys consider this more invasive than monkeypatching, which is capable of causing obscure breakage in far-flung tests. But thanks anyway. You could modify the testing code do an adapter lookup for a component used to do the HTTP client stuff, and then arrange to register your dummy object in a test. I imagine that this would be useful for more than just testing; for instance, if I want to purge a whole tier of Squids, right now the only way to do that is to write a proxy-proxy (one version I wrote once was called PageAssassin) which distributes the PURGE request to them. An adapter-based scheme would allow me to replace the stock version with one which distributed the PURGE directly.

By the way, this issue reminds me: We haven't figured out how to handle Zope 2's version.txt at all! I totally forgot about it. Zope 2 expects a version.txt in Zope/lib/python, but zpkg has no way to support a data file that isn't in a Python package. So there would be no way to package it nor to install it (I don't think distutils knows how to install a non-package-related datafile either). I propose that the future place for Zope 2's version.txt is the Zope2 package. Some code inside Zope 2 that reads version info from version.txt would have to be changed for that, though. This should be fixed for the 2.9 beta, meaning today. I'm outside svn+ssh access range right now, so either you do it, Andreas, or you wait until I'm at home in about 5 hours.

Re: [Zope-DB] Z SQL equivelant of MySQL's SQL_CALC_FOUND_ROWS?

I wonder how the two methods compare efficiency-wise? Yes, well, we're talking about MySQL specifically ;-) Well, with reference to Zope we shouldn't be... Maybe although I sometimes why MySQL does anything: the documentation seems to imply that many decisions were sort of let's do it like this: cf. particularly the recommendations for writing queries with JOINs. Personally I do not see it as valid SQL to predicate a query on what was just asked. Sorry, not a lot of this paragraph made sense :-S It still does to me. Have you had your morning tea? It's not that important. Regarding the original question: if I know I am working with LIMITs or result sets then this implies I don't want to know the total size of the results beyound len(results). Not so. Think of batches: Now showing Results 5 - 10 of 25 But why not just return all the rows and only show 5 of them? Now showing Results 5 - 10 of 25 Yes, let's talk about batches - ZSQL doesn't implement batching so it collects the whole set of results available so len() is available. I agree that this is likely to be inefficient for large results but it doesn't require any additional calls. Or you do as Dieter suggested an run two calls - first one simply counts and the second one effectively does batching. Result sets aren't supported directly so unless the DA provides a method to query on the connection or cursor you will also have to run a separate query with count(). Which means: it would be nice if ZSQL supported batching, preferably by result sets and this means the DAs have to expose more of the underlying functionality and getting more information from the Python driver.
