Hello zope, Acquisition is really cool and amazing .. if it works..:D but sometimes it doesnt. for example, i have a folder "/admin", in that one i have an "options" admin has an index_html, options doesnt. options have a title property, admin too... but they are not getting rendered by <dtml-var title>... i have a real_index.html in the options folder... in which it does correctly render it... why isnt the acquired index_html rendering the variables ? i think i am too lame, or zope is too lame... but not both ;D hope i am ... thanks a lot:D k. -- don't believe everything you think

CMF/Zope scalability
by Tom Cameron 08 Aug '02

08 Aug '02

I have a client who is interested in using the CMF to build a very large system. I am wondering where I could find some proven metrics on its limitations. In particular, how many members could be handled using the standard Zope acl_users methods. I am not worried so much about load capacity, that can be tested using common techniques. But I am not certain about the ZODBs ability to store large numbers of objects and the Catalog to handle searches over these objects. Do you know of any sites/research where I may find some answers? Naturally I understand that this depends on many other factors, but can anyone provide me with actual experiences? Thanks Tom

Tracker Issue
by Juan Pablo Romero 08 Aug '02

08 Aug '02

Hello! I have two questions regarding the Tracker: * Is it possible to delete an Issue? * I left empty all the email fields for the supporters, because I don't want to send email to anybody each time a new Issue is added. The problem is the Tracker then sends email to the administrator's address. How can I configure the Tracker so that it doesn't send emails at all? Juan Pablo

Xron
by George Stroussopoulos 08 Aug '02

08 Aug '02

Hi. I have been using Xron 0.0.10 inside Zope 251. I have a problem in xrondtml method. It seems that when i schedule a xron event to run at a specific time, it runs but it fails to reschedule itself for the next run. It always fails to rescedule and disarms the xron (time goes to 1970 [datetime(0) not in eventtime + reschedule interval] [the method i call with xron runs correctly]. I use xron in several parts of my code. It works fine in a part of code [it manages correctly to reschedule itself] but when i am trying to trigger it manually i get the message to download it.In other part of code it works only manually an not in the background procedure. Below is a part of the code to help you: I use xron inside a class called AllChannelsFolder. In the init method i wrote: def __init__(self, id, title, description,proxy_server_url, theContainer): """ Acquire the parent properties """ self = self.__of__(theContainer) self.id = id self.title = title self.description = description self.proxy_server_url = proxy_server_url self.discoveryExecuteAt=DateTime()+1.0 # initial value is tomorrow self.discoveryPeriodDays=0.0 #Initialise the periodic discovery event newEventId=id+'_XronDTMLMethod' newEventTitle=title+' Discovery method (using Xron)' discoverFile='<dtml-call expr="this().findAllChannels(REQUEST)">' newEvent=XronDTMLMethod(newEventId, newEventTitle, discoverFile, self.discoveryExecuteAt, self.discoveryPeriodDays) self._setObject(newEventId, newEvent) self.discoverXronDTMLMethod=newEvent Inside the findAllChannels method that xron calls : ... in the end of code i have this: if REQUEST is not None: try: u=self.absolute_url() except: # Log the catched exception # logExc(__name__, TRACE, MSG_URL_COMPUTING_EXC) if rfind(REQUEST['URL']) == -1: # We are in the manage_trigger() or in the trigger() method of the Xron contained object # Redirect to portal URL, i.e. URL2 u=REQUEST['URL2'] else: # We were called from the Discover tab => use URL1 for redirection u=REQUEST['URL1'] u2=u+'/manage_workspace' REQUEST.RESPONSE.redirect(u2) return self.loadingError The above code works fine when i schedule it, but it does not work with the manually way[trigger].

Selective replication between Zopes?
by Jean Jordaan 08 Aug '02

08 Aug '02

Hi all Our Zope app -- Creme, for Customer Relationship Management -- is going distributed .. Resellers in various countries are going to be running local Creme instances. Creme administers customers. Each reseller should get only their own customers to administer. A reseller can add and edit customers, and the mother company can add and edit customers for all resellers. When customer instances change, they should be synced between the relevant reseller and the mother company's Creme or vice versa. My question is: what is a good pattern for this scenario? 1 ZEO would be perfect, but it replicates all objects to all clients. We want to replicate specific objects to specific clients. 2 Clients can poll: "What objects have changed since my last sync?" and then sync (pull) those objects. 3 Servers can accept subscriptions from clients, and maintain queues of changed objects to sync (push) to each client. We'll probably do syncing via XML-RPC in the manner of ZSyncer. I guess some implementation of either 2 or 3 would work, though the devil's always in the details .. I'd like to ask whether there are any examples out there? Regards, -- Jean Jordaan Upfront Systems http://www.upfrontsystems.co.za

2.6.0a1
by Tom Deprez 08 Aug '02

08 Aug '02

Hi, just a tiny question, I'm trying to run Zope 2.6.0a1 on a Debian, but I always get the following error: ./start: "A user was not specified to setuid to; fix this to start as root" Then when I do the following, ./start -u root; I get: "/var/local/Zope-2.6.0a1/var does not have the sticky bit set; fix this to start as root." At the moment I'm out of possible ideas, I tried several things including changing permissions etc, but I always end up with above errors. Thanks in advance, Tom.
