Updating BLOB fields in Interbase database
by Ashley 29 Jul '05

29 Jul '05

I'm not sure if this is the right place for this, if not, my apologies. I've got a Clients table in an interbase db with various fields, one of which is a BLOB field (subtype text), used to maintain some notes. When inserting a Client into the table, this field populates fine. However, when attempting to update the client, for some reason, it won't. It just will not allow me to do an update with the notes field in the statement. I've googled around, and found lots of bits helping with Delphi, and lots of statements that BLOB fields in Interbase are tricky to update, but nothing that helps. Has anyone out there found a way around this? I'm using currently using gvib as my database adaptor, as kinterbase does not seem to want to install at all (seemingly problems with ldap ..). My Zope instance is installed from a Plone installer. Zope Version (Zope 2.6.1 (binary release, python 2.1, win32-x86), python 2.1.3, win32) Python Version 2.1.3 (#35, Apr 8 2002, 17:47:50) [MSC 32 bit (Intel)] System Platform win32 Thanks in advance Ashley

Hi, Concerning the zserver-threads config param... If I have an http-server, ftp-server and webdqv-source-server and if my global zserver-threads param is set to 10, does it mean : a)The the max number of http-server + ftp-server + webdav-source-server threads will be 10 ? b)The max number of http-server + ftp-server + webdav-source-server threads will be 30 (3 zservers) ?

Hi I have zope-2.7.2 installed but I can't seem to log into zope with the emergency user. I followed the instruction: cd /usr/lib/zope bin/zpasswd.py access Username: superuser Password: Verify password: Please choose a format from: SHA - SHA-1 hashed password (default) CRYPT - UNIX-style crypt password CLEARTEXT - no protection Encoding: Domain restrictions: and then I did /etc/init.d/zope restart but I still cannot log into zope. Am I doing anything wrong here? Thank you

Suppressing dupes in a concatenated ZCatalog query.
by abgillette＠allmail.net 28 Jul '05

28 Jul '05

Hi All, I have a ZCatalog with two text indexes, news_subj and news_text. Each ZCatalog item also has a unique numeric ID. I'd like to search news_subj and news_text simultaneously, with the results checked for duplicates. In other words, if catalog item 1001 has the word "foobar" in both the news_subj and news_text fields, I only want it to show up once in my search results. Here's what I've got, so far: <dtml-in expr="mp_catalog({'news_text':'foobar'}) + mp_catalog({'news_subj':'foobar'})"> <dtml-var news_subj><br> </dtml-in> This correctly searches both fields, but, when "foobar" appears in both news_subj and news_text, the result is displayed twice. Can anyone give me a pointer on suppressing dupes in a concatenated ZCatalog query? I'm sure there's an easy answer, but I haven't been able to find it. Thanks in advance, Aaron

Re: Zope Foundation Update
by Matt Hamilton 28 Jul '05

28 Jul '05

Pre-amble: I post this as a principal in a decently-sized Zope-focused business in the UK. Our company is also partnering with ZEA for some work. I will try to correct some of Rob's factual errors, and set the record straight for some of the issues discussed here. I am not an official spokesperson of ZEA, though - so bear in mind that what I'm saying here reflects what *I* (and my company) think about the situation, and not what ZEA thinks. I know a bit about why the decision to register the trademarks in Europe was made, why the managing partners of ZEA authorised it, and what's going on on the other side of the fence. I am reasonably neutral, though - and care more about what happens to Zope the *community* than anything else. - Matt Hamilton, Netsight On Wed, 20 Jul 2005 01:07:25 +0200, Rob Page <rob.page(a)zope.com> wrote: > We are sorely disappointed that > ZEA is unwilling to transfer the marks quickly and > quietly so that we can proceed swiftly toward the > formation of the Zope Foundation. This is wrong. ZEA offered you to transfer the trademarks if you covered the expenses involved in the registration (including the salary of the trademark professionals involved in the registration process), no strings attached - but Zope Corporation declined, and was more interested in sending threatening letters about trademark abuse, even though ZEA is the rightful owner of these marks in Europe at the moment. They were more interested in having the matter resolved *their* way than to cover the actual costs involved in registering the trademarks from ZEA's side. > We have offered to reimburse the registration fees paid > by the ZEA to the WIPO (World Intellectual Property > Organization) in order to facilitate the transfer. We > have further offered to preserve their license to use > the Zope mark in the conduct of their business as an > association of Zope companies. Aidan McGuire of Blue Fountain (another UK zope company), Xavier Heymans (of ZEA) and myself had a conference call with Lois Snitkoff from ZC on the 12th of July in which we offered to transfer the trademark if ZC contribute to the fees of the registration and, in the unwillingness to transfer the trademark to the ZF, at least agree to some form of 'social contract' that states the uses and rights of the mark. After consulting with others within ZC Lois' reply stated: "Just to let you know quickly, we will not be paying any of the costs incurred when you registered our trademark. I have checked with management and they reiterate what our position has been consistently." Which directly contradicts what is said above. > In the three weeks since learning of ZEA's illegitimate > registration of our marks we have tried diligently (but > unsuccessfully) to get ZEA to unconditionally transfer > the rights of the registration. The registrations were not illegitimate, the Zope trademark was not registered anywhere but in the US at this point, so it was done as a defensive move to make sure the trademark was in friendly hands. In Europe you have companies/trademarks like ZOPEN that could have been problematic for the registration and approval, so a decision was made early on to secure the trademark for the Zope *community*. The companies that constitute ZEA make up a large part of the professional Zope companies in Europe, and they have a lot to lose by the brand being insecure in Europe. And in what way does not accepting ZEA's offer, to transfer the trademark to you by covering the costs involved in the registration, constitute "try diligently"? > ZEA's registration represents an abuse of registration > and management of international trademarks and the > misappropriation of a mark that is clearly the property > of Zope Corporation. So why is Zope Foundation being used as a pawn in the corporate strategies of Zope Corporation? I find this unclear intent pretty disconcerting. > We know that the establishment of a fair trademark > license for the entire Zope community is an _essential_ > component of the Zope Foundation. It is possible that > we will come to a conclusion with the ZEA prior to the > conclusion of a trademark dispute process. So why are you unwilling to put the Zope trademark under the ownership of Zope *Foundation*? Again, Zope Foundation is being used as a pawn in the company strategies of Zope Corporation. > As an aside, the ZEA has also registered the Plone logo > as a trademark. It is not our business, but came as a > surprise to us, that the Plone Foundation is not the > owner of the Plone trademark. Not true. ZEA's trademark experts helped Plone Foundation register the Plone trademark initially, and promptly transferred the ownership of the trademarks to the Plone Foundation, just as they are willing to do the same for Zope Foundation. Personally, I find it interesting that Zope Corporation insists on ownership of the trademark instead of putting it in the Foundation. The moment Zope Corporation goes bankrupt, any company can buy the remnants and name their interesting Java/.NET technology "Zope", and use the brand recognition to their advantage. Additionally, Zope Corporation is free to grant a company *exclusive* usage of the trademark "Zope" in any country. Say, for example that they decided to partner with a UK company to provide Zope services in the UK - that company could be granted exclusive rights to use the trademark Zope in that country, which I'm sure a lot of companies would have an issue with. After all, they have spent all this time building the brand of a competitor. This is very unfair to the companies that have spent time and effort building the Zope brand - which should be collectively owned by the community - hence Zope Foundation. If your trademark protection is supposed to make any sense, Zope *Foundation* should have ownership of the trademark - not Zope Corporation. ZEA at this moment represents more of the Zope community than Zope Corporation does. I find it a sad state of affairs when Zope Corporation has to resort to these tactics instead of seeking an amiable resolution to the matters when a solution is available. -Matt -- Matt Hamilton matth(a)netsight.co.uk Netsight Internet Solutions, Ltd.

How can I manage permissions for imported ZPT files? Relevant lines from my Product: from AccessControl import ClassSecurityInfo class MyClass(....): security=ClassSecurityInfo() comment_add_form=PageTemplateFile('zpt/comment_add_form',globals()) My goal is to limit access to comment_add_form to the Authenticated role only. comment_add_form is on the filesystem, in my Product's zpt directory. How can I achieve this? I understand zilch about ClassSecurityInfo... (My Product is based on JMBoring template) -- Milos Prudek http://www.spoxdesign.com - your web usability testing

what the namespace means in Script(python)?
by Litao Wei 28 Jul '05

28 Jul '05

Hi list: In Script(python) binding page. there is some description about namespace binding: When the script is called from DTML, this is the caller's DTML namespace, otherwise it is an empty namespace. Recommended value: |_| (underscore character) But in zope book, when talk about Error Handling in the Advanced Page Templates chapter. It looks that it use ZPT with script's namespace. See below. For more flexible error handling you can call a script. For example: <div tal:on-error="structure here/handleError"> ... </div> Any error that occurs inside the |div| will call the |handleError| script. Note that the |structure| option allows the script to return HTML. Your error handling script can examine the error and take various actions depending on the error. Your script gets access to the error through the |error| variable in the namespace. For example: ## Script (Python) "handleError" ##bind namespace=_ ## error=_['error'] if error.type==ZeroDivisionError: return "<p>Can't divide by zero.</p>" else: return """<p>An error occurred.</p> <p>Error type: %s</p> <p>Error value: %s</p>""" % (error.type, error.value) So what happened with namespace when calling Script from ZPT?

2 Zope instances on a 2 CPU linux server
by Pascal Peregrina 28 Jul '05

28 Jul '05

Hi, I would like to know what if using taskset (CPU affinity utility on linux) to bind each Zope instance to one single CPU can improve overall performance of both instances in any way ? As far a I know, python can not fully take advantage of 2 CPU cause python threads are not OS threads. Thanks.

product organization
by Nicholas Wieland 28 Jul '05

28 Jul '05

As usual, my question is rather simple :) I'd like to know what are the best practices for product organization - for example I have _tons_ of queries to sqlserver, and my main class is becoming less manageble every time I look at it :/ I like the way SQL integrates in Zope, what I don't like is having a giant __init__ and a lot of _sqlSomething at the end of the class. Can I associate queries to something else than a _variable ? Something like a dictionary or a class ? Can I move SQL calls outside the initializer ? I'd prefer to have a class for data access and another one to glue all the parts together, maybe I'm plain wrong but I think that my product would be a lot cleaner. What are the best practices for FS based products ? --------------------------------- Yahoo! Mail: gratis 1GB per i messaggi, antispam, antivirus, POP3
