[ANN] ZShell 0.6
by Jerome Alet 09 May '01

09 May '01

Hi, ZShell 0.6 is now downloadable from: http://cortex.unice.fr/~jerome/zshell/ Thanks to Michel Pelletier and Peter Bengtsson for their help. New features: ============= - An unneeded pack doesn't throw an ugly error message anymore. - Security checks: it is now safe(r) to let everyone use zshell. Don't know if all security checks are complete and/or correct, but it's far better now than before. WARNING: no security check is done on: restart, shutdown, pack and lrole but the rest should be OK. - Multiple identical error messages are displayed once. - Some bugfixes. - Commands lsprop, delprop, addprop and setprop added. - UI changes for configurability, but still need to modify the source, but at least it's at the top of it. - The dynamically set action modifier of the form is now statically set to 'zshell', the problem many encountered probably came from that (please confirm/infirm). Please report bugs and comments at: alet(a)unice.fr Thanks in advance. Jerome Alet

MailHost on Windows NT?
by abg＠comco-inc.com 09 May '01

09 May '01

I'm running Zope 2.3.2 (binary release, python 1.5.2, win32-x86) behind IIS on a WindowsNT box. Does anyone have any experience setting up MailHosts on NT? I keep getting the following error when trying to send email: Zope Error Zope has encountered an error while publishing this resource. Error Type: SMTPHeloError Error Value: (501, 'Invalid Address') It looks as though there's some sort of authentication issue between Zope and my SMTP server, which is odd considering they're on the same box. Even when I configure the SMTP server to allow all relaying, Zope can't get through. Any suggestions will be greatly appreciated. Aaron

newbie question: execute permission denied for "python" upon install
by birgit kellner 09 May '01

Apologies if this is too trivial a question: When executing ./install (on a unix machine), I get the following error message. ".../Zope-2.3.2-linux2-x86-/bin/python: 0403-006 Execute permission denied" Now, I did a chmod 755 on python, but the error message persists. Any clues? birgit

Ok, now I've done it. Yes I am a newbie. I was editing my permissions and then tried to relogin. Zope wont accept any user names, including the emergency user. I tried running zpasswd.py and restarting ZOPE but I still have the same problem. Is there any way to reset the permissions back to the default install? Thanks for any help you can provide. -Matt

Of course, you will probably need to obey some conventions to give this function a chance to find the constructors. Dieter

I do not understand what you say here.

First question: Why do you want to do this? I would instead check, whether I was entitled to do some operation. This could use: <dtml-if "_.SecurityCheckPermission(_,<permission>,<object>)"> ... Second question: Did you look at the embedded Zope help -> API Reference -> Authenticated User You will find there a method "hasRole". > (3) (Not just) For a kind of skin technology I need parameters that > are user specific (REQUEST variables)... to set and analyse them may be > no problem - but how can include new parameters to the old URL without > deleting the old parameters? What I need is a way to add parameters to > the REQUEST environment... The REQUEST environment and the URL are quite different things. To extend the request environment: <dtml-call "REQUEST.set(<key>,<value>)"> To extend the URL (provide you know, it has already parameters): &dtml.-URL;&<name>=<dtml-var "<value>" url_quote_plus> Maybe URL:http://www.dieter.handshake.de/pyprojects/zope/book/chap3.html would be good reading for you.

As you are in a Python product and not hampered by (sometimes stupid) Zope security restrictions, there probably is nothing simpler than: l= filter(None,l) This removes any false element, empty elements in your case.

Python does not impose a serious limit (independent on the word size). If the C library and the underlying operating system can handle files larger than 2 GB, then Python can do, too. If you upgrade your C library for large file support, you may need to reconfigure and regenerate Python as the file access interfaces are not binary compatible. Dieter

HTML forms: how to get the value of an unchecked checkbox?
by Stephane Bortzmeyer 09 May '01

09 May '01

I made many HTML forms with Zope but now, I need checkboxes. If I try: <FORM action="handleForm"> <INPUT TYPE="checkbox" NAME="sugar" CHECKED>Sugar?  <INPUT TYPE="checkbox" NAME="milk">Milk?<BR> <INPUT TYPE="submit" NAME="submit" VALUE="Order"> </FORM> The Python Script handleForm cannot run if Milk is unchecked. This is because HTML browsers only send the value of the checkbox if it is checked. The URL sent looks like: http://progress.netaktiv.com:9673/Tests/handleForm?sugar=on&submit=Order (do note there is no Milk) and the error message is: --------- Site Error An error was encountered while publishing this resource. Invalid request The parameter, milk, was omitted from the request. Make sure to specify all required parameters, and try the request again. --------- Of course, milk is in the parameters of the Python Script, but how can I say that it is optional and should default to false? Using "milk:boolean" as its name changes nothing. Zope 2.3.2 (source release, python 1.5.2, linux2)
