[EMAIL PROTECTED] wrote: Hi, The problem is inside postgresql ! They use OID type for LOB and for table'oid, PoPy (to simplify LOB handling) detect automagically LOB and returns them to the end user who can handle them easily. I study the postgresql sources on the CVS and they haven't resolv this problem. We have to write this in the BUGS file we plan to add soon in our release. If you have any proposals to resolv this BIG problem ? I'm sorry for this but postgresql types are very confused. Best regards. So, if I understand correctly, oids are handled as large binary objects? From what I see, oids are 6 bytes in length (using SELECT length(oid)...) since they have a max value of 4 billion, that leads me to believe that only 4 bytes are used as a numeric value. So, they are really just a glorified int4 with 2 extra bytes tacked on for some reason. Anyhow, why exactly does this cause PoPy to crash? I can surely work around this problem for now, but I can certainly see cases where returning an oid would be an essential function, especially if you are working on a generalized database tool. I am certainly willing to help get this fixed. Any additional information you (or anybody) has regarding this would be greatly appreciated.

[Zope-dev] RE: SQL Alias leak....
Making the corresponding change in Results.py appears to have corrected the SQLAlias problem. I'm not exactly sure why the SQLAlias solution is any better than doing it this way. Seems less obfuscated to me. The SQLAlias is better because otherwise Record allocates 3x the memory for each record (thinking that the aliased names are distinct fields). In any case, Jim tracked this down to a subtle bug in ExtensionClass that is fixed for 2.2.5 b1 (which I'm uploading the zope.org now).

[Zope-dev] Re: zPoPy oid issues
Actually I found that the Postgres length function returns the string length (i.e. number of digits) of a number, so my previous message was wrong about the byte length of an oid. AFAIK they are 4 byte integers. I have found a way to retrieve oids without crashing Python or Zope. You must do an explicit type conversion to a 4 byte integer like so: SELECT int4(oid) FROM foo; This behaves in a much friendlier manner. I would still like to see the problem resolved, as I find the fact that an innocuous SELECT query could crash Zope a bit troubling. -- | Casey Duncan | Kaivo, Inc. | [EMAIL PROTECTED] `-- ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )

[Zope] index_html woes + more.... :-(
Hello! I am at loss on the following problem: I have an index_html DTML-document that is only a skeleton to let me design my site around it, based on a common structure. In index_html I call various of dtml-documents and dtml-methods, like "main_pane" and "main_msg_box", etc. The idea I had (and that actually worked for some time) is that I need not implement an index_html file in every sub-folder in my zope installation, but that it would get inherited (aquired???) by all subfolders and that I only needed to make a "main_pane" method, and a "main_msg_box" document. However this is not working, anymore I might add. I cannot say what I have done wrong. The only thing I've done is to add and remove SiteRoots with SiteAccess2 (which btw i cannot make work, and has caused my zope to die abruptly, w/o leaving trace in the logs). I don't know if this is related, but i thought i'd mention it anyway. Can anybody hint me in any direction? Please?

To prevent this, I installed SiteAccess and I put a SiteRoot in the root of my Zope web. I entered: Base: http://www.mydomain.nl/ Path: / Since then I can't access http://www.mydomain.nl/manage. I do get the password-box and frames, but both frames show 'Not Found'. Not Found The requested URL //manage_workspace was not found on this server. Opening the frame in a new window and removing the second / doesn't solve the problem. I looked up the docs of SiteAccess and found setting a environment variable and restarting Zope would help. So I tried that: # SUPPRESS_ACCESSRULE=1;export SUPPRESS_ACCESSRULE # env ... shows SUPPRESS_ACCESSRULE=1 ... # /etc/init.d/zope restart Restarting Zope... done.

Re: [Zope] standard_error_message woes!
* Jason Byron ([EMAIL PROTECTED]) [001223 01:04]: There are two files: /lib/python/ZPublisher/HTTPResponse.py /lib/python/OFS/Application.py that contain error pages hard coded in. you get the HTTPResponse.py code for errors like: 403: 'Forbidden', 404: 'Not Found', 405: 'Method Not Allowed', stuff like that. This error code is not parsed like normal dtml and so you can't simply replace it with: """dtml-var standard_error_message""" I think this is because these are standard error codes that have to do with the web server and they must work even if the object database doesn't. There must be a more detailed reason why these errors aren't connected to the db, but someone else will have to answer that one. :) Well I'm very tempted to start mucking in and letting it call an 'external' python method of some sort. At the very least, I'd like the page to be able to look up a list of 'words' and redirect to a webpage if it matches Like: http://site.org/fish It finds the keyword fish, and sees there is a legit URL: http://site.org/software/beta/fish And redirects it.

[Zope] Zope eating CPU/RAM - how do I find the culprit?
Our production Zope machine has developed a habit over Christmas where it starts eating CPU and RAM (one Python thread on 100% CPU time, and I've seen kernel messages indicating that Zope was killed because it hit an out-of-memory condition which means it sat on ~500Mb RAM).

[Zope] Example activity-explicit workflow system
For those interested in workflow systems and workflow within Zope, the following workflow system may be useful to try out. It models workflow steps explicitly and a workflow becomes a graph with a visual editor. I have been meaning to send along some resources in this area I have been accumulating. The Endeavors group at UCI developed this and the peer-to-peer system they built, Magi, is now at www.endtech.com as open source. They are still developing the workflow product but an early prototype you can download and play with is at: http://www.ics.uci.edu/pub/endeavors/endeavors.html See also the papers and the web-based workflow thesis at: http://www.ics.uci.edu/pub/endeavors/docs/papers/ There was discussion of graphical system to present workflow. I have looked at several, including the AtT stuff. When I have time, I will send a separate email with some that I have found. One thing to look at which is ActiveX based at the moment is http://www.lassalle.com/ A general purpose Flowcharting/Diagramming ActiveX control. I am very interested in a general, fairly full featured workflow system on top of Zope as opposed to using an external workflow product for a fundamental reason. While one could come up with a way of getting what I need with an external system, it would be messy. I need workflows to be explicit and versioned. We make use of ZODB to version content that end users generate. We don't make use of Zope's versioning but use or own hierarchical version tree which is easy to do in Zope. End users generate new workflows and revisit past workflows. The user sees this versioning as notebook pages using a scientific notebook metaphor. It is much cleaner to use ZODB and ZPublisher to do all this instead of having a version tree in Zope and a bunch of correspondences to outside objects in an external workflow system. Thus, there is a lot of value in having a fairly general workflow system whose representation and publishing uses ZODB and ZPublisher. There seems to be a principle here on how to layer systems correctly on top of ZODB and ZPublisher or any persistant-object web publishing system. One way is very clean and simple and other ways are nightmares.

I can't seem to completely change a zclass meta type. When I make a change on the "basic" tab of the zclass, my change seems to take, and the new meta type is displayed in the form. But when I try to add an instance of this metatype, I still see the old meta type name in the dropdown. When I try to reference objects by metatype in my code, the new name does work, so it appears that the new metatype is ... mostly ... applied. Is this a bug? Or is the some other location where I also need to change this info? -- Geoffrey L.

[Zope] inserting half a dtml tag into a zclass
OK, I'm sorry for the wierd title, but I can't
really describe what I want to say very easily in one line.
Basically, my problem is this;
- I have a zclass called DEHS with catalog_aware
and dtml_document as base classes.
- DEHS instances have a selectable property of
public/private.
- I want to be able to make it so that if the
property is set to 'private', then only people on a particular network may
access it. So, here is what I have done (and it works),
dtml-call "REQUEST.set('available',
0)"dtml-if "propertyLabel(availability) ==
'private'"dtml-call "REQUEST.set('available',
1)"/dtml-if
dtml-call "REQUEST.set('dom',
_.string.split(REQUEST.REMOTE_ADDR, '.'))"dtml-if "dom[0] ==
'192'"dtml-if "dom[1] == '168'"dtml-call
"REQUEST.set('available',
0)"/dtml-if/dtml-if
dtml-if "available == 1"dtml-in
PARENTSdtml-let
PARENT="_.getitem('sequence-item')"dtml-if
"PARENT.hasProperty('dehs_site_root_folder')"dtml-call
"REQUEST.set('restricted',
PARENT.absolute_url())"/dtml-if/dtml-let/dtml-indtml-call
"RESPONSE.redirect(restricted+'/restricted.html')"dtml-else
dtml-var standard_html_header
dtml-var
standard_html_footer/dtml-if
So, what's the problem I hear you ask. Well,
I don't really want all this code to be visible (or breakable) in every DEHS
instance. What I would really like to do is have this,
dtml-var privacy
dtml-var standard_html_header
dtml-var standard_html_footer
/dtml-if
where, dtml-var privacy is just all of the
code that I have above s_h_h.However, zope will not let me do this because
I end up with a dtml-if thatis missingits closing tag, and
one that does not have an opening tag. I realise that I there are products
already designed with the sort of functionality I am after built in, but I will
not have much influence on the products that will be available on the server
that this site will end up on... which is why I'm doing it in this
way.
Any input is much appreciated.
cheers

Re: [Zope] is it possible to import from Excel
When on a windows platform, I prefer to define an ODBC datasource on the excel spreadsheet, write ZSQL method that selects the fields to be imported, write a DTML method that iterates on returned records and call another ZSQL method that writes into Gadfly. You may need to handle None/Missing values to prevent from ending up in gadfly as 'None' etc. Ayhan ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )
