Hi Benno, Take a look at Chris Allen's files here: <http://www.zope.org/Members/kmem/tz_aus>. I never used them myself. (I'm not exactly in an Autralian timezone ;-). Cheers.

Storing changes in ZODB, without keeping old versions
by Itamar Shtull-Trauring 26 Nov '99

26 Nov '99

The ZCache Product I created has one major problem - every time it updates itself it'll make the ZODB grow, since it stores all the old contents it had. I don't want this to happen - there's no reason why anyone should undo a change to the cache. I do however want the contents of the ZCache to be stored on disk when it gets moved out of the Zope cache, so I don't want to use volatile variables. Is there any way to do this? Or is it impossible? -- Itamar S.T. itamars(a)ibm.net

I guess it will be something like.... <OPTION value="manage_addProduct/YourProduct/www/methodAdd">Whatever ...for your original version, and... <OPTION value="manage_addProduct/YourProduct/methodAdd">Whatever ...for the new. This happens because it's using the object's __name__ attribute, which unexpectedly includes a / in the first example. A cleaner solution to the problem is..... manage_addPythonMethodForm=HTMLFile('www/methodAdd', globals(), __name__='methodAdd') However, I don't think its related to copy/paste problems :-(

bug in PythonMethod.py (2)
by Ava 26 Nov '99

26 Nov '99

Hello, Forgot the rambling about the 'minus 1' problem. I didn't understand what _v_selfish was for. It is the number or arguments one has to supply to activate the self=currentobject trick So the expression has to be written: self._v_selfish = (fc.co_varnames and fc.co_varnames[0]=='self' and (fc.co_argcount - len(f.func_defaults or ()) - 1)) -- Cordialement, Jephté CLAIN minf7(a)educ.univ-reunion.fr PS: répondez sur minf7(a)educ.univ-reunion.fr, et pas sur ava(a)dde974.equipement.gouv.fr

bug in PythonMethod.py
by Ava 26 Nov '99

26 Nov '99

Hello, I found (what I think is) a bug in PythonMethod.py version 0.1.2 from the PythonMethod product around line 133 (and 246), we have the following expression: self._v_selfish = (fc.co_varnames and fc.co_varnames[0]=='self' and (fc.co_argcount - len(f.func_defaults) - 1)) len(f.func_defaults) is not correct because when your function has no default argument, it is None, and len(None) raises a TypeError. I changed this to read: self._v_selfish = (fc.co_varnames and fc.co_varnames[0]=='self' and (fc.co_argcount - len(f.func_defaults or ()))) But it seems that I have to drop the 'minus 1' to get a correct behavior is func(self, args='') selfish? I think so, but with the 'minus 1', it turns to be wrong! What do you think? -- Cordialement, Jephté CLAIN minf7(a)educ.univ-reunion.fr PS: répondez sur minf7(a)educ.univ-reunion.fr, et pas sur ava(a)dde974.equipement.gouv.fr

Let's say I call that pythonmethood kb, then I'd do something like this: <dtml-var kb> or even better &dtml-kb; and kb would just return the final string I'm looking for (file size in KB). -- Ethan "mindlace" Fremen you cannot abdicate responsibility for your ideology.

Problem editing index_html in Zclass
by Harry Henry Gebel 26 Nov '99

26 Nov '99

I have an index_html DTML Method in a ZClass called ProfileClass, I am unable to open this method for editing in Xemacs. Here is the problem, I tried to open it with: /127.0.0.1:/Control_Panel/Products/Profile/ProfileClass/index_html but got a message that the file did not exist. I then opened /127.0.0.1:/ and changed "directories" until I got to /127.0.0.1:/Control_Panel/Products/Profile but when I looked at this listing ProfileClass was not marked as a "directory" so there was no way for me to cd to it. I tried moving the index_html method to Profile thinking that perhaps ProfileClass would acquire it from Profile, but it didn't work. Is there any way for me to edit this directly in Xemacs with EFS or will I have to open it in the Zope management interface and use cut and paste to enter it? I am using Zope 2.1.0b2 on Linux Mandrake 6.1 w/ the included python (1.5.2) . ---------------------------------------------------------------------- Harry Henry Gebel ICQ# 43675297 West Dover Hundred, Delaware ----------------------------------------------------------------------

What I need is quite different from what a mailing list program like ezmlm or Mailman does - The newsletter is one-way only - no user submissions, no question/reply threads. - I need full control over the format of the newsletter - can't just email entries to the list manager. - Users can only register and de-register, so I don't need user-accessible configuration screens. - This site will eventually get a user registration system for customizing the interface (Portal Toolkit?), and I'd like to use the same registration interface for the newsletter. So if I wanted to use a mailing list program, I think I'd have to do a lot of work to force it into my desired frame: My Zope registration code will have to register users with the mailing list. Then I'd have to email each news item to the mailing list so it gets included in the next digest. And I'd have to hack the program code to control the digest format. Looks like a whole lot of work trying to force an inappropriate tool to do what I want. The only part of a mailing list system I really need is the bulk mailer. I need to do the user registration inside Zope anyway. And the content gets generated by Zope so I don't need the mailing program to format it. I just need something that can deliver a message to 10,000 recipients quickly and efficiently, and has support for suspension of recipients that bounce too often. Is anybody familiar with Mailman or ezmlm enough to tell me how hard it would be to bypass all the mailing list handling functions and get straight to the bulk mailer? Or, is there a standalone bulk mailer program I can use? One other thing: This site is hosted on a dedicated server in a web farm (yes, I'm 100% buzzword compliant), and I would need a very good reason to justify getting a second server. Since my newsletter won't receive email and will only mail out once a week, can I expect to get by with running it on the main server? Or will mailing out 10,000 messages at once kill the Zope server performance for an hour every time?

Australian time zones?
by Benno Rice 26 Nov '99

26 Nov '99

Does Zope's DateTime class know about Australian timezones? I did a grep through lib/python/DateTime/DateTimeZone.py and didn't get any results. If they're not there, how can I add them? -- Benno Rice "No, no.
