SuSe uses /sbin/rc*. RedHat uses /etc/rc/rc*.

Depending on distribution there are tools like chkconfig under RH, or update-rc.d for Debian which make the symlink process easy and self-documenting, automatically creating all the correct kill and start links in one command > *Or*............. just use Windows if you'd rather not be bothered > with the learning curve on these kinds of issues. <shudder> In all seriousness that's hardly a valid option in a great many cases, and even more hardly a valid excuse as the learning curve is neither large or complex. Given the numerous init scripts in a standard installation which can be used as working examples, and the fairly obvious documentation on what runlevels are at the top of (most Linux) /etc/inittab or the init manpage, the learning curve for someone who either knows or is about to know Python is not significant. > I'm serious.

In working with Windows refugees and those new to computing I've normally found I can cover the area enough to give them a working knowledge, eough to understand the base concepts of runlevels and how and when they might need to use them in their use of the system, in about 10 - 20 minutes (depending on how many Window based assumptions needs to be unlearned first). This is starting with someone from ground zero -- no prior knowledge. With Zope we can make more useful assumtions: that the person has both some technical interest and ability, that he has some basic programming experience or interest and thus understands at least the basic concepts of process flow control, and simple scripting. Given those not insignificant head starts, figuring out runlevels should really only be a matter of a few minutes. > For a newbie, the *nix/Zope combination requires a serious time > investment. In the Debain world installing Zope is a trivial as: # apt-get install zope and waiting a couple minutes while its sucked off the network and installed (there are a couple config prompts along the wang, but nothing confusing). The Debian Zope pakcage maintainer (who I belive is on this list) has both done a good job, and is responsive to questions. For Redhat systems I'm told that there are RPMs available which install equally if not more trivially. As I no longer run any RH systems I can't verify this however. -- J C Lawrence Home: claw(a)kanga.nu ----------(*) Other: coder(a)kanga.nu --=| A man is as sane as he is dangerous to his environment |=--

patch for worldpilot to add 'imapserver' and 'smtpserver' options.
by Anthony Baxter 31 Jan '00

31 Jan '00

The attached patch changes the 'add WorldPilot' screen to have options for 'imapserver' and 'smtpserver'. I've pretty brutally hacked the code to pass this through to the appropriate bits of the system where required. It seems to Work For Me. Anthony

aquisition problem
by Terry Kerr 31 Jan '00

31 Jan '00

Hi, I am having a problem with aquisition within a python product...well I don't think I understand it properly yet. I have a folder inside a product, and an object within that folder. A view of that object allows the user to call a function from the base class of the product. That function tries to get the id of the object that called it. The function that is called is access by the URL: /home/product/folder/object/function I would have assumed that self.aq_parent would have done the trick, but it returns the name of the folder that contains the product (home), and self.id returns the name of the product. How can I get into context which object the method was called from? terry -- Terry Kerr (terry(a)adroit.net) Adroit Internet Solutions (www.adroitnet.com.au) (03) 9888 8522 0414 938 124

Property Sheets
by Dyon Balding 31 Jan '00

31 Jan '00

Hi, I am creating a Python Product for Zope. I have a container object that contains a number of objects. I want these objects to inherit a number of attributes from the container, with the objects specific values. If an attribute is added at the container level, the objects should pick up this new attribute. This is the functionality supplied by Property Sheets in ZClasses, however I feel more comfortable developing my product as a whole from a lower level. So I would like to graft a Property Sheet into my Product, however I am having trouble working out the details. Has anyone done anything similar? I'm going through the ZClass code, but not having had much experience with Python classes, it's heavy going. Has anyone got any advice or pointers to code or documentation?. The other option of course would be to just implement it myself, but if I can get some pre-existing code to work, I'd be much happier :). thanks -d -- Dyon Balding, email: dyon(a)adroitnet.com.au work: +613 98888522, mobile: +61 0414992604 Adroit Internet Solutions

Accesscontrol on dynamically created objects
by Sascha Matzke 31 Jan '00

31 Jan '00

Hello, I have an objectfactory which return dynamically created objects. These objects are returned as object.__of__(objectfactory, object) to maintain some of the acquisitio magic. But it seems that those objects doesn't have any accesscontrol (the class inherits the RoleManager class) on them... any ideas ??

Question on Folder Structure strategy...
by Robert Geiger 30 Jan '00

30 Jan '00

I have noticed strange behavior when browsing my web site as I build it. For example, take this structure: \-- \Folder1 \Folder2 \Folder3 I make a web page with an index on the left side for ALL PAGES Folder1 Folder2 Folder3 Which are links of the form <a href="Folder#">Folder#</a> If I consecutively click through these links, the browser shows my current page as follows <Click> Folder1, http://Folder1 <Click> Folder2, http://Folder1/Folder2 <Click> Folder3, http://Folder1/Folder2/Folder3 This is NOT what I intend, nor will the second or third work if bookmarked that way. What am I doing wrong??? Thanks in advance for your assistance.

Re: [Zope] PTK bug?
by Jules 30 Jan '00

30 Jan '00

| I installed the Portal Tool Kit in my Zope directory (2.1.1), and then | tried to import ZopeOrg.zexp... [snip] To quote Paul Everitt during his talk at 8IPC, "the portal tool kit does not work right now. Don't use it." There was no firm date for release of one that does work but I think he said something about it being ready in February or March. I could be wrong as it was bloody cold up there any my mind hadn't quite defrosted for his talk. They did show a pre release PTK that was awfully nice. It removed a lot of the complexity of the standard Zope interface that drives non technical users nuts. I don't think my granny could use it but maybe my mum could be shown how in about 20 minutes. The PTK seems to be something that everybody has been bleating for and DC has been promising for a while. It seems that they're deadly serious about putting one out Real Soon Now. Otherwise showing it during Paul's session would be a bit on the silly side. Cheers, Jules
