oops. I keep forgetting Reply All -----Original Message----- From: Paz [mailto:paz@chello.nl] Sent: Thursday, March 15, 2001 7:26 AM To: Dieter Maurer Subject: RE: [Zope] FTDraw Thanks for the tip Dieter, but indeed, the __init__.py is there. However, you say that the _init_ is necessary. Is this more of a zope thing? It says in the PIL docs for the latest, that the PIL.pth is the all-important package identifier. I tried moving it around, also with no avail. What gets me confused is when PIL in in the products area, the message is: (when PIL is in /Products/PIL) Cannot import Products.TextImage yadda yadda.. No module named PIL.Image (when PIL is in /bin/PIL) Cannot import Products.TextImage yadda yadda.. No module named Image Is it me or is the compiler decreeing that it finds it but its being stubborn? Pil is being a pill...

Duh... can the compiler read or has > the third bottle of wine FUBAR'd me? Can you verify, that "PIL" contains a "__init__.py" file. Some broken unpackers remove empty files. But "__init__.py" is essential, even if empty. Dieter

bobo_mod_time difference in zcat vs object
by Joel Burton 15 Mar '01

15 Mar '01

First of all, apologies for the dozen questions over the past week. Zope's learning curve gets very steep as one takes the first steps through the API, and the many responses here have been very helpful. I have a series of books that are JBook ZClass objects. They (naturally) have a bobobase_modification_time of when the instance was last modified. I have a catalog, BookCatalog, that holds the JBooks. The default index for bobo_mod_time is and default metadata for it are there. If I clear the catalog, re-find JBooks and look in the catalog values, I can see that a particular book has a bobo_mod_time of today. But: when I iterate over the query results, I see a bobo_mod_time of yesterday. For example: <dtml-in "Catalog.searchResults(meta_type=['JBook'])" sort=bobobase_modification_time reverse> <dtml-var title> from_obj: <dtml-var "getObject().bobobase_modification_time()"> from_cat: <dtml-var bobobase_modification_time> </dtml-in> returns different values for my book from_obj (today) and from_cat (yesterday), even though when I looked in the cat, I see today for bobo_mod_time. What I'd like is the bobo_mod_time of today, since that's when I actually changed the object! I've cleared and re-found my objects, and this doesn't fix the problem. I am not using RAM cache or any other (intentional) caching objects. Any ideas? Thanks! -- Joel Burton <jburton(a)scw.org> Director of Information Systems, Support Center of Washington

Catalogs

Does anybody know how to delete the references to items in a catalog since deleting alone does not seem to accomplish this. When a search is done I don't want any references to that object. thanks

asyncore.poll
by Randall F. Kern 14 Mar '01

14 Mar '01

Recently my development site has started getting _really_ slow a few times a day. Stopping and restarting Zope makes it quick again. When it's in this slow state, I open a python interpreter and run Zope.debug() to get profile information. This profile shows a huge amount of time being spent in asyncore.poll() (like 25 seconds on a 25.2 second request). I'm running ZEO and Zope 2.3.1b1 on Linux. Any ideas? Thanks, -Randy

update on 2.3.1 b2...
by Brian Lloyd 14 Mar '01

14 Mar '01

FYI - I mentioned yesterday that we were planning to get the 2.3.1 beta 2 release out today (Wed). For any who may have been waiting expectantly, I'm pushing this off until tomorrow so that we can track down a few last-minute test failures that cropped up. Stay tuned...

Change password
by Daniel Rusch 14 Mar '01

14 Mar '01

Yes it is in the acquistion path, it is a root level property! I know that is what the problem appears to be, but how can changing a password cause it not to find a root level password??????? Your problem is that it cant find BoxName, is that visible in the Acquistion? -- Andy McKay. ----- Original Message ----- From: "Daniel Rusch" <drusch(a)globalcrossing.com> To: <zope(a)zope.org> Sent: Monday, March 12, 2001 3:28 PM Subject: [Zope] Manage > All, > > Zope 2.3.0 (binary release, python 1.5.2, solaris-2.6-sparc) > Python Version 1.5.2 (#8, Nov 16 1999, 10:05:41) [GCC 2.8.1] > System Platform sunos5 > > We have a page that allows users to change their password it executes > the following: > > > <dtml-call "REQUEST.set('name', login_name)"> > <dtml-call "REQUEST.set('password', password)"> > <dtml-call "REQUEST.set('confirm', confirm)"> > <dtml-call "REQUEST.set('roles', > acl_users.getUser(login_name).getRoles())"> > <dtml-call "acl_users.manage_users(submit='Change', REQUEST=REQUEST)"> > > > The password is changed and the user is taken to a page that notifies > them that their password was changed, but when the user tries to > navigate to any page instead of getting an Authentication dialog, they > get a NameError for a variable that is (or should be) there. > > It is as if the Name Space is lost?
