Our development Zope 2.5.0 crashes frequently
by Graham King 15 Mar '02

15 Mar '02

Hi all, any thoughts? Has anyone had this experience? (and would you like to?) Our Zope development system is used by a small team of developers, up to 6 people. It has been crashing and restarting automatically 6 or 7 times a day, much to the annoyance of our programmers. I use both Stupid_log_file and "-M" detailed log file to record everything I can, and have grabbed requestprofiler.py, which is a very useful tool (Thanks!). (an aside, is there any other logging I can do, aside from coding something?) All our developers interface with the Zope "manage" function, as one would, and go directly through port 8080 (Z HTTP). One suggestion I have made is to access it via the FastCGI interface instead, just to see what impact that has. The Detailed Log shows me variously that for no apparent reason, GET /manage, /manage_main, or /some-product/subdir/sub/something/manage_workspace and so on cause this failure, which results in: zdaemon... Aiieee! 13215 exited with error code: 138 (or 139) I had asked you all last week, about what this above meant, and Jens & Dieter kindly told me descriptions are to be found in the OS's lib/errno.h file. Now, we use Solaris and/or openBSD, and this file helpfully says this number (in a range) is used by Xenix, and is thus not documented. [Footnote: I keep all emails, but somehow I managed to delete this single one from Jens - damn!] Thanks in advance, if you can shed light on this.... ------------------------------- Graham King Host Services Team Leader OzEmail Internet +61 2 9433 2747 graham.king(a)team.ozemail.com.au www.ozemail.com.au -------------------------------

Properties in a propertysheets unreachable
by Peter Bengtsson 15 Mar '02

15 Mar '02

In a ZClass you can define a couple of propertysheets and stick properties in there that can be access from the instance like a "normal" property. # Explicit way print context.propertysheets.get('myproperties').getProperty('age') # ...or simpler: print context.age I'm developing a python product and now I can't reach my properties from my templates. I must use the explicity way to get to the values. # This works <div tal:replace="python:here.propertysheets.get('properties').getProperty('name_cookiekey')"></div> # This doesn't (which used to work when the product was a ZCLass) <div tal:replace="python:here.name_cookiekey"></div> What do I need to do to get simple access to the properties in the propertysheets I have?

Sync Zope ext. method with a another process (Unix)
by Gilles Lenfant 15 Mar '02

15 Mar '02

Hi, I need to wake up a (non Zope) process (or daemon) from an external method. This process is a long term process that cannot be run in sync with the external method (that returns in an asynchronous manner). Any idea for this ? Thanks in advance. --Gilles

ZSession (Newbie-)question
by Simon Brun 15 Mar '02

15 Mar '02

hi On my zope-site, I have a logging form. After a user logged in successfuly, a session (with ZSession) with the item "user_id" is set. If he wants to post a comment to a news article for example, there is a check if he have an active session or not. When he is logged in he can post. If he is not logged in, he have to login first. This works just fine... But, when a logged in user surfs to a subdomain (e.g. forums.mydomain.com) the check failes and the user have to login another time. A new session will be created... How can I create a session for the hole site? Not for every subdomain? thx for helping a newbie ;) Simon

Database adapter connections
by Michal Bukovjan 15 Mar '02

15 Mar '02

Hello, I have a database adapter, Level3 (inheriting from Shared.DC.ZRDB.TM). All documentation I have found claims that such an adapter should be able to open multiple connections to the database, I see always one though. What am I missing? More detail : ---------------------- I have a folder, a database connection object, ZSQL method and a DTML document, that renders the ZSQL method. Zope is running in 12 threads. I call the DTML document from 8 simultaneous clients, the DTML document however renders one at a time (it takes a while to render), apparently serialized by the database access. There is only one (!) physical connection to the database, I would expect at least 8. How do I speed things up? I looked at DCOracle2DA as reference, cannot see a difference. Thanks for any hint, Michal Bukovjan

zope without apache

Just installed zope 2.16 and squishdot from debian packages on an up to date potato box, and I would like it to serve on port 80. I don't have apache installed and have no need for it. What is the simplest way of accomplishing this? Thanks, -Herb herbert(a)ns.sympatico.ca

Re: [Zope] DCOracle2 question
by tgraham＠speakeasy.net 15 Mar '02

15 Mar '02

If I understand the question, you could add a ZSql Method like 'select * from view_name' then add a Z Search Interface and bind it to the newly created sql method and that should give you an idea of how sql and zope work. There may be a more proper way to do it via Page Templates but I'm still trying to wrap my brain around those. hth, Todd On 15 Mar 2002, =?iso-8859-1?Q?Miguel_Rodr=EDguez?= wrote: > Hi you all, I have installed DCOracle2 in my > Zope Server (Linux), and it works fine.

ReplaceSupport mangles ZSQL methods....but...
by Tony McDonald 15 Mar '02

15 Mar '02

Hi all, The *otherwise excellent* ReplaceSupport mangles ZSQLmethods in that the body of the method (the SQL) and the arguments gets mixed over. It's a dead easy fix though, check out the Zope API and you'll see that manage_edit for ZSQLmethods is defined as manage_edit(title, connection_id, arguments, template): Whereas in the Handlers directory of ReplaceSupport, the file ZSQLMethod.py is; def manageEdit( self, ob, body, params='' ): ob.manage_edit( ob.title, ob.connection_id, body, params ) Change it so's its; def manageEdit( self, ob, body, params='' ): ob.manage_edit( ob.title, ob.connection_id, params, body ) And bobs your uncle...
