Thanks a lot for replying... I still a newbie at this ... in order for shapelib to read shapefile, you need a set of three files(.shp, .shx, .dbf). so, if I have to download this to a temp location into my computer filesystem, could you show me how this is done? ----- Original Message ---- From: Andreas Jung <lists(a)zopyx.com> To: Allen Huang <swapp0(a)yahoo.com>; Zope <zope(a)zope.org> Sent: Sunday, December 24, 2006 2:47:52 PM Subject: Re: Fw: [Zope] problem with the shapelib module.. help -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - --On 23.

I really wonder why you think it would work the same way? The hierarchical object storage of Zope looks similar to a filesystem but it is not a filesystem and the Python APIs for accessing filesystems don't apply. We have no idea what the ShapeFile constructors expects as data. If it expects a filename of a file within the filesystem then you must obtain the content of your data stored within the ZODB, create a temporary file and call the constructor as you did within your external method. Possibly the constructor accepts the data directly as *string*..in this case this would make things a bit easier. But it is up to *you* to check the Shapelib API and take appropriate action. - -aj -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (Darwin) iD8DBQFFjiKYCJIWIbr9KYwRAk0oAKCSyEo5ykswElgi9jFGWf89NthzmwCfRvEM nSMyeIu/cK7NpecUlof2BR8= =B0Mw -----END PGP SIGNATURE----- __________________________________________________ Do You Yahoo!?

problem with the shapelib module.. help
by Allen Huang 22 Dec '06

22 Dec '06

I want to do some mapping application with zope.. but I have run into this problem over and over.. in "Run Zope in Console" Exception exceptions.AttributeError:"ShapeFile instance has no attribute 'thisown'" in ignored in web browser Site Error An error was encountered while publishing this resource. Error Type: IOError Error Value: new_ShapeFile failed I change some setting to my runzope.bat because I want zope to use python2.4.4 instead of the build 2.3.5 because I have install shapelib module(pyshapelib-0.3.win32-py2.4) which is the module I want to use for the import of my external methods. The runzope.bat looks like this: @set PYTHON=C:\Python24\python.exe @set ZOPE_HOME=C:\web\Zope\Zope @set INSTANCE_HOME=C:\web\ZopeInstance @set SOFTWARE_HOME=C:\web\Zope\Zope\lib\python @set CONFIG_FILE=C:\web\ZopeInstance\etc\zope.conf @set PYTHONPATH=C:\Python24\Lib;%INSTANCE_HOME%\lib\python;%SOFTWARE_HOME%;%PYTHONPATH% @set ZOPE_RUN=%SOFTWARE_HOME%\Zope2\Startup\run.py "%PYTHON%" "%ZOPE_RUN%" -C "%CONFIG_FILE%" %1 %2 %3 %4 %5 %6 %7 I made a very short python external method to test the shapelib module import shapelib, dbflib def testShapeLib(self): f1 = shapelib.ShapeFile('C:\\web\\ZopeInstance\\taipei.shp') but all I get out of it is the above two errors anyone have any idea what i'm do wrong with my settings or my code? any thought? __________________________________________________ Do You Yahoo!?

Too many ZODB object loads...
by Suresh V 22 Dec '06

22 Dec '06

On the database Activity tab in the Control Panel, I am seeing a high number of Object Loads (400K per hour). My cache size if 60K from what I see in the Cache Parameters tab, each of the 4 threads is well within this limit. My database has about 1M objects. The symptom is that Zope appears slow when adding/editing content. Any idea if this is a problem? Suresh

external method, not escaping < and >
by Mihamina Rakotomandimby 21 Dec '06

21 Dec '06

Hi, I have an external method that fetches some web content (POP messages) then format an HTML output to make it easy to display. the Id of the external method is "mm". So as I said, it returns HTML content, with HTML tags and "<"s and ">"s. I directly call that external method from a ZPT this way: <div tal:content="python:here.mm()"> foo </div> the problem is the ">" and "<" returned by "mm" are all transformed to < and >. How to avoid that? Thank you.

RFP: Zope/Plone Performance Audit
by Marshall Mayer 21 Dec '06

21 Dec '06

Good morning/evening, LiveModern (http://livemodern.com) is a fairly active and visible community-oriented Zope/Plone website that is experiencing performance problems after a migration from Plone 2.0.5 to Plone 2.1.4. The site is functioning well after the migration, except for performance. But because Zope/Plone is such a complex system, we're having trouble finding the performance bottleneck that our visitors/ members consistently report ("it's soooo slow"). From the end user perspective, most anonymous visitors do not see performance problems due to our caching scheme. When they hit a page that needs refreshing, it can be quite slow however. But where the problems really raise their ugly heads is for authenticated members (our members contribute all content on the site, so this is a BIG problem). Their experience is often very slow, sometimes for navigation but mostly for adding/editing content, making the site mostly unusable for our content providers. From an administrator's perspective, we can see that the CPUs seem to be always working overtime. We're pretty sure we can fix the problem (it's probably a configuration solution), if we can just find what's holding the site up. We're confident Zope and Plone is up to the task for our site, if we can get Zope and Plone (and everything else we have installed to increase performance) set up right. We just need some fresh eyes to look at the problem, and know it will probably take a bit of your time inside our site to find it. After you review our server setup below, we'd be interested in your analysis of our site, and your recommendations on how to increase performance. If you are interested in providing this service, please respond ASAP with a cost estimate and timeline for your services. Those that can complete the analysis and recommendations before January 1, 2007 will be given preference. Marshall LiveModern Hardware: * Apple Xserve G5, dual 2.3 GHz PPC G5 processors * 6BG RAM * dual SCSI hard drives on RAID * dedicated T1 connection LiveModern Software: * Mac OS X Server 10.4.8, all software updates applied * Zope 2.8.7, Plone 2.1.4, Python 2.3.5 running behind Apache and Squid * CacheFu 1.0.1 and ZEO installed * Main Plone content products include Ploneboard 1.0 and SimpleBlog * 1M objects in ZODB LiveModern Traffic: * 16K registered members * 40K unique visitors/month and dropping rapidly (from 80K/month 3 months ago) * 200K page views/month and dropping rapidly (from 400K/month 3 months ago)

problem using rdflib with zope profiler
by Lucie Lejard 21 Dec '06

Hi, I am using the default profiler of zope (in zmi/Control_Panel/DebugInfo) to trace the calls when I go on a specific template. This template is using a Five view that has methods using the rdflib.

change manage_addFile
by Kate Legere 20 Dec '06

20 Dec '06

I copied the code from manage_addFileFolder so that we can upload files into the filesystem but I'd like to amend it so that we can specify the target folder rather than just having the file uploaded to the folder in which the form resides. How would I do that? I've looked through the code in OFS that handles this but am not sure how to add the folder as a variable.... (I;ve tried a couple of things unsuccessfully) manage_addFileForm=HTMLFile('dtml/imageAdd', globals(),Kind='File',kind='file') def manage_addFile(self,id,file='',title='',precondition='', content_type='', REQUEST=None): """Add a new File object. Creates a new File object 'id' with the contents of 'file'""" id=str(id) title=str(title) content_type=str(content_type) precondition=str(precondition) id, title = cookId(id, title, file) self=self.this() # First, we create the file without data: self._setObject(id, File(id,title,'',content_type, precondition)) # Now we "upload" the data. By doing this in two steps, we # can use a database trick to make the upload more efficient. self._getOb(id).manage_upload(file) if content_type: self._getOb(id).content_type=content_type if REQUEST is not None: REQUEST['RESPONSE'].redirect(self.absolute_url()+'/manage_main') Katie
