ZODB error when trying to index object (Input/output error)
by Felix Ulrich-Oltean 23 Jun '05

23 Jun '05

Hi I get the following error when certain new objects are added into a plone site - when archetypes tries to set the UID, it asks the catalog for all unique values of the index "UID". I;ve never had input/output errors before from the ZODB. There's definitely enough space on the drive and objects are added fine - it's just that the UID is then not set, which breaks all sorts of Archetypes stuff. Any ideas how I can hunt this one down? Thanks, Felix. 2005-06-20T13:15:26 ERROR(200) ZODB Couldn't load state for 0x111310 Traceback (most recent call last): File "/usr/local/zope/lib/python/ZODB/Connection.py", line 597, in setstate p, serial = self._storage.load(oid, self._version) File "/usr/local/zope/lib/python/ZODB/FileStorage.py", line 689, in load return self._load(oid, version, self._index, self._file) File "/usr/local/zope/lib/python/ZODB/FileStorage.py", line 662, in _load h = read(DATA_HDR_LEN) IOError: [Errno 5] Input/output error ------ 2005-06-20T13:15:26 ERROR(200) Archetypes None Traceback (most recent call last): File "/zope/global-products/Archetypes/Referenceable.py", line 69, in _register cid = archetype_tool.registerContent(self) File "/zope/global-products/Archetypes/ArchetypeTool.py", line 681, in registerContent cid = self._genId(object) File "/zope/global-products/Archetypes/ArchetypeTool.py", line 659, in _genId keys = catalog.uniqueValuesFor('UID') File "/usr/local/zope/lib/python/Products/ZCatalog/ZCatalog.py", line 562, in uniqueValuesFor return self._catalog.uniqueValuesFor(name) File "/usr/local/zope/lib/python/Products/ZCatalog/Catalog.py", line 425, in uniqueValuesFor return self.getIndex(name).uniqueValues() File "/usr/local/zope/lib/python/Products/PluginIndexes/common/UnIndex.py", line 445, in uniqueValues return tuple(self._index.keys()) File "/usr/local/zope/lib/python/ZODB/Connection.py", line 597, in setstate p, serial = self._storage.load(oid, self._version) File "/usr/local/zope/lib/python/ZODB/FileStorage.py", line 689, in load return self._load(oid, version, self._index, self._file) File "/usr/local/zope/lib/python/ZODB/FileStorage.py", line 662, in _load h = read(DATA_HDR_LEN) IOError: [Errno 5] Input/output error

RE: [Zope] developing with zmi: how to move a patch from data fro m devel to live?
by Pascal Peregrina 23 Jun '05

23 Jun '05

You can manually export objects from your dev zope to individual files and then import them back to the live instance through ZMI. You could try this : http://zsyncer.sourceforge.net/ It will enable you, for built-in Zope object types (but then you can extend it with your own types) to list the differences between your dev and live zope instances and deploy your changes. Pascal -----Message d'origine----- De : zope-bounces(a)zope.org [mailto:zope-bounces@zope.org]De la part de gabor Envoyé : lundi 20 juin 2005 08:35 À : zope(a)zope.org Objet : [Zope] developing with zmi: how to move a patch from data from devel to live? hi, my problem is the following... imagine that you develop something for the customer using zope. while developing you use the ZMI a lot... to set some settings, to create python scripts and so on. you do this on the 'devel' server. then you deliver the solution to the customer (to the 'live' server). you can simply copy the data.fs stuff to the live server. after some time the either customer wants some new features, or there's a bug to fix or something like that. now you create the fix/improvement on the devel server. but now how do you move the improvement/fix to the live server? you cannot just copy the data.fs over. the customer already has some content/data in it... one way seems to be to not use the ZMI at all. you create an install python script, which calls the methods of the ZMI interface. this way works, but it seems for me to waste my time. finding the right method that the gui calls to call it from the install script seems stupid for me. but it solves the problem. with the script i can really make the changes i need on the devel server. so, is there a solution where i can use the ZMI? how do you solve this kind of problem? gabor _______________________________________________ Zope maillist - Zope(a)zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev ) ********************************************************************** This email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed.

general design question
by Erik Myllymaki 23 Jun '05

23 Jun '05

I am making a small application for sales and marketing reports in-house. Each user has a unique login/username in zope (via NtUserFolder) and they also have a unique employee_id in exisitng SQL database tables. Each page calls numerous SQL methods almost all of which need to know the employee_id number. I can make a small method getEmpID(request.AUTHENTICATED_USER) and map the logins to the employee_ids, but then I am calling that at least once every page. I could call getEmpID(request.AUTHENTICATED_USER) once when the user logs in and then set it in a cookie or a session variable but I am unsure of the possible security issues in doing that. Or I could start using the zope/NT login as the key in various sales and marketing tables. Just thought I'd *throw it out there* for any input, thanks.

ZopeProfiler and Zope 2.8.0

Hi, I would like to know if anyone has tried using ZopeProfiler (1.4 version from http://www.dieter.handshake.de/pyprojects/zope/) with Zope 2.8.0 It was working fine with Zope 2.7.6 but it appears to cause the instance to hang with Zope 2.8.0...

RE: [Zope] External editor for ZMI
by Jim Abramson 23 Jun '05

23 Jun '05

I do recommend Boa Constructor, which feels the most like you're actually editing source code files (though you're editing the zope objects in place). This program has actually saved my life. Caveats: It has a few dependencies you'll need to track down, and it's a little buggy/quirky. If you're not comfortable with a bit of DIY, or you're relatively new to zope and/or python, it might be more trouble than its worth. The 'upload' mechanism in ZMI for most objects might do OK for you, then you can use whatever editing environment you want. I'm sure a lot of people have solved this particular problem for themselves in different ways, based on their own editing needs/preferences. After a little trial and error, of course.

Search path for objects
by John Poltorak 23 Jun '05

23 Jun '05

Does Zope look anywhere apart from the current folder for objects which are specified like this:- ? <link rel="Stylesheet" type="text/css" href="ploneCustom.css" /> I've cobbled together a website and can't work out where certain CSS tags are being specified. Is there a simple way to determine this? -- John

ZODB performace/banchmarks
by Tamas Hegedus 23 Jun '05

23 Jun '05

Hi, Two months ago I red about the ZODP that it has high performace, can store high amount of data, but there are no banchmarks e.g. for comparison for RDBMS. Are these true? If yes, why is not created a banchmark or something like that?

Using Zope to Manage an Asset Inventory Database
by Spann, John W. 23 Jun '05

23 Jun '05

I run a local area network of about 200 Microsoft Windows based workstations and about 15 servers. The inventory consists of various pieces of information (make, model, serial number ...) relating to CPU, monitor, keyboard etc. At the present time, the computer inventory is maintained using an Excel spreadsheet. I would like to move/convert this inventory information into Zope, but I am having some difficulty in making the transition. My thinking is to have a hierarchy of objects. A CPU object, monitor object, keyboard object, tape drive, disk drives, etc. Some CPUs and monitors are spares and sit in a storage room. I would like to be able to use Zope and the ability to cut and paste objects to manage this information. If a monitor on a working CPU fails, I would like to be able to launch Zope, find the monitor, remove it from the existing system, pick one from the storage area and logically attach it to the working CPU. In addition, I would like to be able to generate reports/lists for auditing purposes. root |--> storage area | -> monitor | -> monitor | -> cpu | -> keyboard |--> room 1 | -> system 1 | -> cpu | -> monitor | -> keyboard | ->system 2 | -> cpu | -> monitor | ->keyboard |--> room 2 | -> system 3 | -> cpu | -> monitor | -> keyboard |--> room 3 | -> system 4 | -> cpu | -> monitor | -> keyboard I have been looking for examples of how this is done within Zope, but I have not found any working examples. Any thoughts on how to implement a system like this would be much appreciated. -- John W. Spann 410.765.4427 (Work) 410.232.0730 (Pager) Text Message: 4102320730(a)archwireless.net

Cached Variables
by calisp＠gmail.com 23 Jun '05

23 Jun '05

Hi, I am developing an application that is a front end to an RDBMS. Sometimes, when loading a page, several scripts get called that all require the same information from the database. It would obviously be costly for each script to call the same ZSQL method. My method for avioiding this senario is... Get the scripts to call another script that is a wrapper to the ZSQL method. This wrapper script returns context.REQUEST[value_name] if it exists or, if it does not exist, executes the ZSQL method, stuffs the result into REQUEST[value_name] and then returns it. I am not convinced that this is the right way of dealing with this situation however. Is there a better way? Thanks, Calisp

From Zope 2.5.1 to Zope 2.7.6
by Tim Suter 23 Jun '05

23 Jun '05

I am upgrading our current Zope from 2.5.1 to Zope 2.7.6. I have the new version installed as a different instance on a different server. The Zope 2.5.1 is in tact and what I am wondering is, how do you migrate everything from the older to the newer? I thought exporting the .zexp out of Zope 2.5.1 would be ok. However, when I import it into the new install, it isn't the same as the original. For example, I exported knowledge.zexp from the 2.5.1 and imported into the 2.7.6. Now, when I go to pull up the page that points to info related to this data, the subtopics are now listed below the contents of the original page. In looking at the html (I am no HTML expert at ALL), it did not appear that there was even anything related to subtopics. It must be a control from within the Zope management interface. I guess I just want to know how to migrate properly with little administrative effort. Thanks, Tim
