Silva Performance isses - Memory Error & Broken Pipe
by Jonathan Bowlas 03 Feb '06

03 Feb '06

Hi All, We're running Silva 1.4.1 on the following setup - Zope 2.7.8-final, python 2.3.5 and linux2 but have been experiencing some major performance issues that I'm hoping someone may be able to help me resolve. Having checked the Zope log I noticed it contained a number of concerning entries such as: ------ 2006-01-25T21:08:11 ERROR(200) ZODB Couldn't load state for 0x016b87 Traceback (most recent call last): File "/usr/local/zope-2.7.8/lib/python/ZODB/Connection.py", line 597, in setstate p, serial = self._storage.load(oid, self._version) File "/usr/local/zope-2.7.8/lib/python/ZODB/FileStorage.py", line 697, in load return self._load(oid, version, self._index, self._file) File "/usr/local/zope-2.7.8/lib/python/ZODB/FileStorage.py", line 688, in _load return read(u64(plen)), serial MemoryError ------ 2006-01-25T21:08:19 ERROR(200) ZODB Couldn't load state for 0x028179 Traceback (most recent call last): File "/usr/local/zope-2.7.8/lib/python/ZODB/Connection.py", line 600, in setstate self._set_ghost_state(obj, p) File "/usr/local/zope-2.7.8/lib/python/ZODB/Connection.py", line 639, in _set_ghost_state state = unpickler.load() MemoryError ------ And these: 2006-01-25T20:45:18 ERROR(200) ZServer uncaptured python exception, closing channel <ZServer.HTTPServer.zhttp_channel connected 144.82.100.130:43419 at 0xb0bb9f8c channel#: 1355352 requests:> (exceptions.MemoryError: [/usr/local/lib/python2.3/asyncore.py|write|77] [/usr/local/lib/python2.3/asyncore.py|handle_write_event|397] [/usr/local/lib/python2.3/asynchat.py|handle_write|152] [/usr/local/lib/python2.3/asynchat.py|initiate_send|213] [/usr/local/lib/python2.3/asynchat.py|refill_buffer|202]) ------ 2006-01-25T20:47:12 ERROR(200) ZServer uncaptured python exception, closing channel <ZServer.HTTPServer.zhttp_channel connected 128.40.105.130:59791 at 0xb0b69fec channel#: 1355791 requests:> (exceptions.MemoryError: [/usr/local/lib/python2.3/asyncore.py|write|77] [/usr/local/lib/python2.3/asyncore.py|handle_write_event|397] [/usr/local/lib/python2.3/asynchat.py|handle_write|152] [/usr/local/lib/python2.3/asynchat.py|initiate_send|220]) And this (Although having googled the error I'm pretty sure its nothing to worry about. But I could easily be wrong as I'm fairly new to zope): 2006-01-25T17:06:08 ERROR(200) ZServer uncaptured python exception, closing channel <ZServer.HTTPServer.zhttp_channel connected 128.40.105.130:58015 at 0xae8046ec channel#: 1281272 requests:> (socket.error:(32, 'Broken pipe') [/usr/local/lib/python2.3/asynchat.py|initiate_send|218] [/usr/local/zope-2.7.8/lib/python/ZServer/medusa/http_server.py|send|417] [/usr/local/lib/python2.3/asyncore.py|send|337]) I've attached the log file, although I don't know if this list accepts attachments. Hopefully someone will be able to identify the problem and provide a solution for improving performance or alternatively provide a list of procedures I can carry out to locate the problem myself. Many Thanks. Jon Bowlas University College London.

LocalFS
by Rakotomandimby Mihamina 02 Feb '06

Hi, In order to learn developping for Zope, I want to learn manipulate large files. I read it is not a good idea to store them in the ZODB, so that it couls be a good idea to use LocalFS for example. I intend to use Zope2.9. But LocalFS seems to be an old product. Is there any replacement of it you would know? -- A powerfull GroupWare, CMS, CRM, ECM: CPS (Open Source & GPL). Opengroupware, SPIP, Plone, PhpBB, JetSpeed... are good: CPS is better. http://www.cps-project.org for downloads & documentation. Free hosting of CPS groupware: http://www.objectis.org.

Hi Is there a page anywhere which lists the main benefits of Zope 3? I've had a look around and there is lots of developer information but not so much for the site manager/producer -- Michael

Serve PHP/Perl within Zope
by sharif islam 02 Feb '06

02 Feb '06

Has anyone tried using this method: http://www.zope.org/Members/Mamey/PHP I am little confused about how to serve the actual php content within the files. I added file with this: <dtml-if "REQUEST.has_key('phpScript')"> <dtml-var "ServePHPContent(REQUEST['phpScript'])"> </dtml-if> Then I tried to begin the php content after this and saved it as file.php3. However, when I view zope doesn't render it. --Sharif

Javascript rendering problem?
by Bruno Grampa 02 Feb '06

02 Feb '06

Hello, i've what i think is a rendering problem checked on Zope 2.8.5 and Zope 2.9 (tried on unix and windows os): download from microsoft website the sdk for Windows Media Center (http://www.microsoft.com/windowsxp/mediacenter/developer/default.mspx) Inside there is a folder called HTML Templates. There you can find some html pages designed to be seen on media center. You can normally view them using IE. Now transfer the entire directory inside Zope; if you open the default.htm files the highlight of buttons and objects is not anymore working. IE doesn't complain about any errors, it just don't work. I've tried uploading the same directory to Apache and pages are working. These files are full of javascript but i really can't understand what's happening. Thanks, Bruno

virtualhost/apache2 problem
by zenobito zenobito 02 Feb '06

Hello, I'm trying to set up apache2 to serve two sites, a "normal" one on www.mysite.com and a zope one on www.mysite.com/zope (using rewrite rules). I already know how to put apache2 in front of zope, but in this situation something doesn't work: I read every howto's but when connecting to http://www.mysite.com/zope I get a 404 error from apache2: it seems like mysite.com comes first, so if there is no "zope" folder (actually it doesn't exist), it gets an error. I hope someone can help me. This is my apache2 configuration file.

starter application for zope 2.x
by Tim Nash 01 Feb '06

01 Feb '06

Does anybody have a zope 2.x application that you usually use to start building products with? I have combed the products at zope but they generally are built to demo a particular functionality. I am looking for an application that ties a lot of ideas together such as: 1. something that covers users registration, 2. building tables out of data stored in zodb, 3. getters and setters for objects in the zodb, 4. How to collect a variable in one page and pass it on to another page where it modifies the data displayed, 5. working with Sessions, etc. 6. coverage of the most commonly used DTML snippets 7. coverage of the most commonly used ZPT snippets 8. Test framework with setup scripts I guess what I'm looking for is a template for a real application, not for the individual pieces of functionality. I imagine that some of you who do full time zope development would have at least two of these "starter" applications, One for when the data is primarily stored in the zodb and one for when the data is primarily stored in a relational db. I think an application like this would help people get up and running with building (and testing) zope products. Also, it would help if the products on zope.org where ranked in some way so newbies like me can know what the community has found to work well. Thanks, Tim

Templating language but not XMLish nor DTML
by Peter Bengtsson 01 Feb '06

01 Feb '06

In zope2... I love ZPT for XMLish content like HTML but I'm not that excited about DTML which I use for zopeifying .css and .js files and email texts. What other templating have people had success with in their zope2 apps? -- Peter Bengtsson, work www.fry-it.com home www.peterbe.com hobby www.issuetrackerproduct.com
