CoreSessionTracking timeout question
by Joh Johannsen 11 May '01

11 May '01

I've got an Internal Session Data Container timeout set 30 minutes, but occasionally I will start a new session, and all the session data disappears after a couple minutes. The way I understand it, any time I access session data, that 30 minute timer starts again. Is there something I'm doing wrong here? Thanks, JJ

RE: [Zope] Namespace problem with folders starting with numbers

Ok. Sorry to jump to quickly on that one; I am partially wrong. <dmtl-var expr="_['2000'].id"> will work; so will <dtml-in expr="_['2000'].objectValues()"> (returns a sequence). However, in the case of something like this: <dtml-var expr="_['5000']._['5100'].id"> Zope has some security/permissions issue with that (when I try to run a method with code like this as a manager, I get a basic auth box?).

Folders expose their content through subscription (and through attributes). This means, you can use: "<folder>[<expression evaluation to the content item name>]" That is quite readable. Finally, you can use "restrictedTraverses". Dieter

(you understand what I mean) Your REQUEST variables seem to be "UTF-8" encoded: '\303\251' is the UTF-8 code of 'é'. You have different options: * convince your browser to send "iso-8859-1" encoded data. I think, it uses the encoding that he found in the form constructing page. But others made different experiences. Please look into the (searchable) mailing list archives for the relevant threads. * handle encoding in your own code (DTML or Script). Dieter

I would use the syntax that Oliver specified earlier: <dtml-var expr="_['5000']['5100'].id"> I think that will work...

Yes, eventually using <dtml-with> enables me to reach the property value, by placing a method (using your logic), at the same folder where it finds a folder with numbers as names. That means I'd need at least three methods, but guess this isn't a clean way of retrieving simple property values. How does the community faces this? Do you just don't use numbers as folder names?

RE: [Zope] ZServer Must Be Continually Re-Started

I also have a similar problem (RH v7, Zope v2.3.0); ps aux shows normal python processes, top shows no unusual CPU usage, Z2.log shows the last GET request and that's it, there simply is no response from zope until I restart it. I just enabled verbose logging with the -M switch on z2.py today, to try to get more information. My setup includes ZEO v0.4, does anyone else having this problem use ZEO?

RE: [Zope] problem selecting integers from mysql
by sean.upton＠uniontrib.com 11 May '01

11 May '01

It would have to be out of the range of a 4-byte integer, which is not likely in most applications. MySQLDA sees MySQL INT and INTEGER (4 byte) type fields as longint types, which are also 4 byte integers (which is -2,147,483,248 to 2,147,483,248). I am not sure about MySQL's BIGINT type, which is an 8-byte integer, which is so rediculously big (2^64 or 18,446,744,073,709,551,616 possible numbers), it's hard to imagine anyone using. I'm not sure how Python's __int__() handles an 8-byte value, I cannot seem to find an answer in the Python Reference Manual...

[Tracker]Tracker errors and fixes on HP/UX 11.00 with Pyth on 2.0
by Farrell, Troy 11 May '01

11 May '01

I sent this to the tracker-dev(a)zope.org list, but due to the lack of activity on that list, I think it might be better placed here. When looking at the diffs below, note that I always append a # to a line of code that I edit in someone elses sources. Troy -----Original Message----- From: Farrell, Troy Sent: Friday, May 11, 2001 11:06 AM To: 'tracker-dev(a)zope.org' Subject: Tracker errors and fixes on HP/UX 11.00 with Python 2.0 Hi Guys- I've installed Tracker before on Linux/i386 with Python 1.52 before without problems, but when I try it with HPUX 11.00/Python 2.0 and Zope 2.3.1 or 2.3.2, there are many issues. I seem to have fixed most of them and I felt that you guys could use the fixes, so here we go: 1) Inside the Tracker ZClass, I've changed /Control_Panel/Products/Tracker/Tracker/propertysheets/methods/TrackerItem/p ropertysheets/methods/index_html to include the following lines after the comment at the beginning: <dtml-unless expr="PATH_TRANSLATED == URL0[_.len(BASE0):]"> <dtml-call expr="RESPONSE.redirect(URL0)"> </dtml-unless> These lines fix the problems associated with the TrackerItem ZClass being inside the Tracker ZClass instead of the TrackerIssue ZClass. These problems show themselves inside the manage_tabs method for a TrackerItem's index_html 2) Change all the appends with too many arguments to appending tuples, and change tracker_role() so that it doesn't throw up an error when it tries to convert a tuple to a string, because we can't convert a tuple to a string. Please review the changes to tracker_role() in TrackerMisc.py especially well. I'm not very confident about them.
