ARGH !! SQLSession!
by Paul Zwarts 22 May '01

22 May '01

Help me PLEAAASE! I am using the SQLsession product to use environment settings that are invisible to the user and sensitive to the session. Every so often without fail I get a KeyError about a session parameter. It DOES EXIST! Im not sure what to do to look into it. I've used SQLSession reliably in the past and Im confused where to look for the fault. I have a feeling that the PoPy201 adapter isnt working properly (I get hangs several times a day needing a restart), but I dont see how this would affect SQLsession at work. Is it possible that a hung thread in PoPy is dissallowing SQLSession from doing its SELECT statement causing it to return an error? Paz

RE: [Zope] Vote for Windowing Toolkit to use for Fat Client
by sean.upton＠uniontrib.com 22 May '01

Yuck. Sorry, but for x-platform development, if the Trolls are going to charge for Windows dev. license, it makes no sense to use this as a basis for an x-platform open-source project; this is not just KDE, it has to run on other platforms and still have a free core!!! This would have to run on Win32, and by using a commercial toolkit like Qt, you significantly raise the barrier to entry for potential developers. wxPython is (from the looks of it) going to be the defacto replacement for tkinter, and it is relatively friendly - and I believe wider used - and there is not reason to complain about using gtk widgets on *NIX, because the development is abstracted by a class library (and gtk widgets are much more aesthetically pleasing!). There is a practical (not dogmatic) reason to keep things free: you want to encourage widespread development and contribution, and you won't get that with a limit imposed by a commercial toolkit. What I don't understand is what differentiates most of the frameworks for desktop development (wxWindows, Qt, MFC, OWL, inti, etc), they all try to share the same idea space - but wxWindows at least qualifies as mature, modern, and free.

still dtml-tree
by Klaus Herrmann 22 May '01

22 May '01

Hi! This dtml-tree problem with "hidden" folders again: if i do <dtml-tree> <dtml-unless hidden> <dtml-var id> </dtml-unless> </dtml-tree> it will work fine for folders that do not contain subfolders. otherwise, this [+] will be displayed (what is really not acceptable). do you see any chance do arrange this with the branches_expr="objectValues(['Folder'])" call? that would be great! thanks in advance!

Z SQL method results from a python script
by daniel.a.fulton＠delphiauto.com 22 May '01

22 May '01

I have a Z SQL method named "employ_data" as below: SELECT SUM(employ_hour) AS sum_hour, SUM(employ_salary+employ_hour) AS sum_total, division WHERE employ_record.month=<dtml-sqlvar month type=string> AND employ_record.year=<dtml-sqlvar year type=int> GROUP BY division This method has been tested and returns multiple rows in the result set correctly with input for month, year. I want to use this method in a python script but can't for the life of me get it to return the entire result set. Python script: results = context.employ_data(month=month, year=year) for result in results: return result.sum_hour, result.sum_total, result.division This returns only one record -- the first record in the result set. I need the entire result set. Am I misusing this or have incorrect script? Thanks, Daniel

Security problem in How-To: Caching with mod_proxy
by Ragnar Beer 22 May '01

22 May '01

Howdy! In the how-to I wrote about caching with mod_proxy (http://www.zope.org/Members/rbeer/caching) there is a security problem insofar that if you setup your server just like that it will be a public proxy that people can use to cover their traces when accessing other websites. To disable this behavior you could e.g. add a LocationMatch directive to your httpd.conf that denies every request that doesn't start with a slash. <LocationMatch "^[^/]"> Deny from all </LocationMatch> To try out the problem and see the effect of the fix configure your browser to use www.mysite.org port 80 as a proxy (assuming the name of your site is www.mysite.org) Then try to access a page from your browser and look at your access_log. Thanks to Ivo van der Wijk for pointing out the problem! Cheers, Ragnar P.S.: I'll be in Switzerland for a couple of days and probably won't have internet access till monday. So if anybody replies and waits for my answer: please be patient ;)
