The other day I have change my hostname. Today I have restart ZOPE and I get follow Error-Message: 2000-08-30T20:12:44 PROBLEM(100) ZServer Computing default hostname Traceback (innermost last): File "/opt/zope/2-1-6/z2.py", line 493, in ? logger_object=lg) File "/opt/zope/2-1-6/ZServer/medusa/http_server.py", line 560, in __init__ ip = socket.gethostbyname (socket.gethostname()) socket.error: host not found Is the changing of the hostname the reason for this? Thanks!

Silly string question

Aaarghhh!!! I want to print the following line exactly as it appears on a web page (no HTML coding).  How do I do that in DTML without Zope cribbing about tags are not good? I got it to print it without using quotes like this <dtml-var expr="''"> However I need the quotes around header.inc too. I tried escaping quotes with \, but doesn't work. I don't want to put <!--include .... Zopistas, I think I'm missing something very basic here. HELP!!! Zope 2.1.6 on NT4. Browser IE5.5 on Win98. vsb http://easy.to/babu/

Indeed, I could reproduce your observation. I analysed the problem and now do understand what went wrong here in my installation: I have 2 vocabularies, both named 'Vocabulary'. One is in my root, the other is in the Etailer "Catalog". When objects are indexed, this happens in the context of "Etailer/Catalog". Therefore, "Etailer/Catalog/Vocabulary" is used for this purpose. When objects are searched for, this happens in the context of "Etailer". Therefore, "/Vocabulary" is used for word lookup. It does know nothing about the words used in my Etailer products. Maybe, in your installation things are similar. At least, Etailer is very volatile when there is another object called 'Vocabulary' above it. This results from line 159 of "Etailer.py": searchResults = ZCatalog.searchResults You should provide a true, redirecting definition for "searchResults": def searchResults(self,REQUEST=None, used=None, **kw): " " return apply(self.Catalog.searchResults,(REQUEST,used),kw) to make it more robust.

I can tell you, that FSSession has the same problem, at least the version before the current one (announced some days ago). I would expect that SQLSession is more robust. But beware, there may well be transaction conflicts, because several threads may try to change the same record in the database. If this indeed happens, than at least one transaction cannot be committed and must be roled back. Dieter

RE: [Zope] ZCatalog and OR searching
by Casey Duncan 01 Sep '00

It would be wonderful if ZCatalog could support something like a SQL where clause for doing complex searching. Is this anything anybody has in the works or would be interested in working on? I forsee something like Catalog(query_expr="title contains 'foo' and not title contains 'bar' or title contains 'spam'"). Support for the simple searching in existence now should of course remain. Perhaps some code could be borrowed from Gadfly or something. I would be interested in working on something such as this, but I don't want to reinvent the wheel. Anyone with futher input or info, please let me know. -Casey Duncan ----- Original Message ----- Date: Fri, 01 Sep 2000 11:43:30 +0100 From: Chris Withers <chrisw(a)nipltd.com> Organization: New Information Paradigms To: Dieter Maurer <dieter(a)handshake.de> CC: Francois-Regis CHALAOUX <Francois-Regis.CHALAOUX(a)sanofi-synthelabo.com>, Receipt Notification Requested <zope(a)zope.org> Subject: [Zope] ZCatalog and OR searching Dieter Maurer wrote: > A ZCatalog search usually combines searches to the different > indexes with an "And". > You want to combine them with an "Or". Don't you wish there was a decent query language for ZCatalog so this kindof rediculous complexiting to achieve a simple outcome wasn't necessary? cheers, Chris PS: The example in the Advanced ZCatalog How-To does away with most of the catalog's advantages (like lazy searches, small results set, etc)

In plain vanilla Zope (i.e. without GUF, LoginManager or some other login catcher) Zope simply raises an Unauthorized exception. This is turned into an HTTP Unauthorized response. Your browser, upon receipt of such a response, pops up the dialog and ask you for username and password. It then automatically reissues the request. > 2.After u give the username and password what is the file / module name > against which the username and password is authenticated. For any request, Zope traverses the hierarchical WebSite object guided by the request's URL. At the URL's end, it reaches some object (or has raised a "NotFound" exception). >From that object, Zope looks back along its path for objects that are able to authenticate some users. Usually, these are objects that contain a "user folder", usually called "acl_users". Authentication is done by such a "user folder". You find the code near the end of "ZPublisher.BaseRequest.traverse". A user folder has a method "validate". It gets the request, authentication information and (optionally) the list of roles necessary to access the target object. It returns a user object, if it can one authenticate for the given authentication information and with the required roles, otherwise, it returns None. If it return None, Zope looks furhter up in the path. If it reaches the end without being able to authenticate the user, it raises an Unauthorized exception (this leads to 1) above). You find Zope's vanilla user folder in "AccessControl.User.UserFolder". > 3.what is this 'manage'....? method/module??? There is none. Dieter

Re: [Zope] Site Access 2.x problem

Hi Joshua, Joshua Brauer writes: > I have Site Access running on the latest Zope (2.2) but I cannot seem to get "Site Root" to show up in my list of available products. Those sites that already have site roots seem to work fine, but I cannot add new site roots. Anybody else having this problem or have ideas? Fetch the latest Zope distribution (2.2.1, not 2.2.1b1), because earlier versions had a logging bug. Start your Zope with a "STUPID_LOG_FILE=zope.log" argument. Look into "zope.log", if you see any message related to "SiteAccess". Dieter
