dtml-sendmail and envelop sender [Q]
by Bruno Mattarollo 18 Mar '01

18 Mar '01

Hello, I have a question I cannot see answered anywhere... Maybe it's there but at least I cannot find it :( We are using Zope as the application server for our cybercentre (we call this to our applications that allow people to send emails to heads of governments, CEO's and so on). It's running on a Linux machine. The MTA is postfix. The workflow is as follows: a user comes to the site and decides to take on to a cyberaction and mail his congresman because he (or she) is concerned about the governement actions on the Artic (to take an example), so this cyberactivist goes to a form were he/she fills in his/her email address and fills on the message, then submits the form. From our side we have a DTML method that uses dtml-sendmail to actually send the email. We need this email to display the FROM header as from the user that filled in the form, so we use to have something like this: <dtml-sendmail MailHost="<our mailhost>"> From: <dtml-var SenderFromForm> To: <dtml-var EmailOfYourCongresMan> ... and so on ... But the issue is if by any of this bad things of life, the email of the congresman is down the bounce will go the the cyberactivist email account (SenderFromForm)! That's really bad! So looking around I noticed that bounces go to the envelope-sender so we did: <dtml-sendmail MailHost="<our mailhost>"> From: <dtml-var OurBounceProcessingAccount> From: <dtml-var SenderFromForm> To: <dtml-var EmailOfYourCongresMan> ... and so on ... But we received a complain that all the emails are showing as coming from the OurBounceProcessingAccount email address. So the question is: how are we suppose to set the envelope-sender and not display the OurBounceProcessingAccount email address in the header of the email using dtml-sendmail? Or is it a postfix issue?

Importing Problem - Z2 CONFLICT Competing writes at
by Ze Octavio 18 Mar '01

Hi All, We are having a problem while importing a .zexp into a clean Data.fs on Zope 2.3.0 with HotFix intalled runing on debian. We already read on this list other messages with similar error messages. We've found a good explanation for the message below from Chris McDonough: "It happens when more than one thread tries to modify the same object in storage at the same time. It's Zope's equivalent of record-locking... It's normal. There's no corruption or anything, it's telling you that it avoided a write that might have caused problems." The problem is how can we get this error if there is only one person, one thread, making modifications to Zope? Despite the error below, the folder with its objects appears to be imported normally. Could it be a corrupted data stored in zexp that I'm tring to import in this new Data.fs? This is the error message that shows up on Zope stderr, when we try to import the zexp: ------ 2001-03-15T15:31:40 INFO(0) Z2 CONFLICT Competing writes at, /manage_importObject Traceback (innermost last): File /home/zope/230/lib/python/ZPublisher/Publish.py, line 175, in publish File /home/zope/230/lib/python/Zope/__init__.py, line 235, in commit File /home/zope/230/lib/python/ZODB/Transaction.py, line 252, in commit File /home/zope/230/lib/python/ZODB/Connection.py, line 270, in commit ConflictError: '\000\000\000\000\000\000\023\226' Thanks in advance.

It's the following statement; "getitem(ver_id).enter(REQUEST,RESPONSE)" that was causing the redirect.

manage_addVersion
by Tim Cook 18 Mar '01

18 Mar '01

Zope 2.3.1b2, python 1.5.2, linux2-x86 I can't stop manage_addVersion from redirecting back to manage_main. I have scoured the normal information sites & sources and there is 'some' information about manage_workspace redirection (in a ZClass) in the archives. That doesn't apply in this case. Being the Python neophyte that I am, the code in Version.py says taht if REQUEST is not None to do the redirect. Well, I've done my very best to set REQUEST to None (actually it looks like it defaults to None) all without success. Any help appreciated; as usual. -- Tim Cook, President - FreePM,Inc. http://www.FreePM.com Office: (901) 884-4126 ONLINE DEMO: http://www.freepm.org:8080/FreePM

Re: newbie zope question -- stuck in quick-start page
by Sundar Narasimhan 17 Mar '01

17 Mar '01

Oh, I have created a new user with Manager role access, and even when I login as that user, I can't seem to get rid of this quick-start page, and get to see the tabbed root folder that appears in all the zope docs. I notice that http://host:8080/manage_workspace gets redirected to http://host:8080/manage.. I guess there's no way to look into the dtml/or code structure of zope except thru the mgmt. interface? (i.e. without that it would appear that I'm just stuck -- since there's quite obviously a bug in the default install that just keeps looping back to the quick start guide no matter what I try). The log file doesn't seem to indicate anything unusual (like errors etc.). Is this thing just broken? ps. is there any documentation on where the content is generated from? (I couldn't find where the quick start page is coming from, for example).

<dtml-let> in and outside <dtml-in>
by Edwin Martin 17 Mar '01

17 Mar '01

Hello, I want to set a variable inside a <dtml-in>-loop and want to use it outside the <dtml-in>. This is probably a FAQ, but I couldn't find the answer. <dtml-let> wouldn't work and something like <dtml-call "REQUEST.set('done',1)"> doesn't work either. I want to have something like this working (simplified): <if stage=3> <dtml-in...> <dtml-if...> <dtml-var bla> <dtml-let done=1> </dtml-if> </dtml-in> </dtml-if> <dtml-if not done or stage=2> ... </dtml-if> Bye, Edwin Martin.

PHP3 from external methods ?
by Geir Bækholt 17 Mar '01

17 Mar '01

Anyone have experience with accessing php3-scripts through external methods ? The nicest way would of course be to have the script act as external methods themselves ,just passing parameters in , and getting return values , but i expect you would have to put some kind of python wrapper between zope and php.. any thoughts on the subject ? - one of our coders wrote a payment system in php3 and oracle, and we would really like to interface zope with it.. The cleanest way would of course be to rewrite the whole thing in python , but, as usual, we don't have the time... -- Geir Bækholt geirh(a)funcom.com
