Zope/Cache/Memory
by kevin7kal 07 Dec '06

I have a database that is just under 200K objects with plans that it will grow larger. The objects are created by using another object with methods that read files and create the objects from the data in the files. When creating the objects, I find I have to manually clear the cache or else zope eventually crashes with an out of memory error. There are 4GB of ram on the server. The same issue arises when I catalog the objects. I am trying maintain as much speed as possible, so I do not want to catalog until the end of the import. Is there a way to programmatically clear the cache during a large indexing to avoid out of memory errors? I am using zeo storages and setting the cache on those to a smaller size has no real effect in this case, because the cache seems to outgrow its defined size when it is very active. Is zope even good for this? Should I consider another database? It still seems that cataloging is an issue whether the objects are stored in the zodb or elsewhere. -Kevin

changing the meta_type for python product class
by Dragos Chirila 07 Dec '06

07 Dec '06

Hi everybody, I am stuck with the following problem for witch I don't have a solution. I would appreciate it very much if you could help me with it. I have a very simple Python product with only one class that extends Folder. The name of the product is MyClass and the MyClass.py module is below: from OFS.Folder import Folder from Products.PageTemplates.PageTemplateFile import PageTemplateFile from constants import * manage_addMyClass_html = PageTemplateFile('zpt/myclass_manage_add', globals()) def manage_addMyClass(self, id, title='', REQUEST=None): """ """ ob = MyClass(id, title) self._setObject(id, ob) if REQUEST: return self.manage_main(self, REQUEST, update_menu=1) class MyClass(Folder): """ """ meta_type = METATYPE_MYCLASS def __init__(self, id, title): #constructor self.id = id self.title = title And the constants.py module contains: import Globals MYCLASS_PRODUCT_NAME = 'MyClass' MYCLASS_PRODUCT_PATH = Globals.package_home(globals()) METATYPE_MYCLASS = 'My Class' PERMISSION_ADD_MYCLASS = 'MyClass - Add Components' In the ROOT folder I create the following python script (listing): for x in container.objectValues(['My Class']): print '[%s] - [%s]' % (x.meta_type, x.absolute_url()) return printed Then I follow the steps: 1. Create an instance with the id 'instance1' (in the drop down I have 'My Class'). 2. I run the 'listing' script and I get: [My Class] - [http://10.0.0.37:8080/instance1] 3. I change the constant METATYPE_MYCLASS into 'My New Class' 4. I run the 'listing' script and I get: [My New Class] - [http://10.0.0.37:8080/instance1] 5. I create a second instance with the id 'instance2' (in the drop down I have 'My New Class'). 6. I run the 'listing' script and I get: [My New Class] - [http://10.0.0.37:8080/instance1] 7. I modify the python script by changing the 'My Class' with 'My New Class' 8. I run the 'listing' script and I get: [My New Class] - [http://10.0.0.37:8080/instance2] In the ZMI for both instances the meta_type 'My New Class' is displayed. I don't understand why the first instance is not displayed after I change the meta_type value in the python Product. Moreover, if I try to explicit update the meta_type property for the first instance to the new value, the result is the same. What I am trying to accomplish is to be able to change the meta_type value and this to work (e.g. with no effect on python scripts like 'listing') Thank you very much, Dragos
