Line breaks...

Anyone have a reasonable technique for splitting uploaded files on line breaks? readlines will not work because the file might have a non-Unix EOL convention (e.g. Macintosh or DOS).

Re: [Zope] SSL

well .. I finally got M2Crypto to compile (wrong version of swig) and when I went to install it is was wanting to overwrite stuff like /ZServer/__init__.py and whatnot so I cancelled out and backed everything up, thank goodness, because when I did let it overwrite them it destroyed the zope server. I tried everything to get this thing back up and had to fall back on the back-ups. It can't be THIS HARD to get a secure connection on Zope! Thanks for your input.

wierd performance difference
by Joachim Schmitz 10 Apr '02

10 Apr '02

I have a ZClass-product with two possibilities to add a new instance of the product: first: normal add through the ZMI second: through a customized versin, which is callable for the user via url. The form is a customized version of the product_add_form, which has a copy of the product_add as action, where only the redirect at the end goes to a different location. Now the weired thing: adding a new productinstance through the ZMI, takes about 20 - 30 seconds after hitting the submit button, and adding it through the customized version takes about 1 - 2 seconds !! In both cases logged in as the same user, who apparently has Manager rights. How can I find out, where Zope is spending its time ? This is Zope 2.4.3 on sun-solaris behind apache.

Huge Memory Leak
by Dean Houghton 10 Apr '02

10 Apr '02

Hi I am creating an application using Zope (Zope Version (Zope 2.5.0 (binary release, python 2.1, win32-x86), python 2.1.3, win32)Python Version 2.1.3 (#35, Apr 9 2002, 16:00:14) [MSC 32 bit (Intel)]System Platform win32) which has a status page which the browser refreshes every 10 seconds. I have noticed that the memory usage climbs by about 20K for each access of the page. When it reaches approx. 100M various parts of the application fail. To try and isolate the problem I cut down the page to the following and decreased the refresh to 2 seconds:- <head> <title><dtml-var title_or_id></title> <LINK REL=StyleSheet HREF="stylesheet.css" TYPE="text/css"> <dtml-comment> <style type="text/css">  </style> </dtml-comment> <META HTTP-EQUIV=Refresh CONTENT="2; URL=show_system_status"> </head> <table align="center"> <tr> <td colspan="7"> <dtml-var "table_title(title_text='Current status of all monitored Systems')"> <tr> <th>System</th> <th>System Type</th> <th>Service Status</th> <th>System Status</th> <th>Graphs</th> <th>Configure</th> <th>Delete</th> </tr> </table> Other parts of the application use up a lot more memory each time the page is accessed. Does anyone have any ideas as to why the memory usage keeps climbing ?? Thanks in advance... Dean Houghton

problems with zope handling large download files
by Albert Ting 10 Apr '02

10 Apr '02

I'm currently using zope 2.3.3, apache 1.3.20, and fastcgi. However, I'm trying to support large http transfers, protected via a acl_user (passwords, expiration, etc.). Each download/transfer could be 20-50mb. I've tried using LocalFS as well as streaming out the data using RESPONSE.write(). However, it appears FCGIServer buffers the *entire* file before sending it out to the apache mod_fastcgi. This won't work for me, as it's a huge memory hog, plus there's a noticeable delay before the buffer is flushed out to apache. An alternative would be not put the large files within the zope process but as an external file. But I need to support passwords/expirations. Is there a better way to handle this? I'd appreciate any help. Thanks, Albert Ting (alt(a)sonic.net)

PHP style variable variables in Python?
by Michael LaPera 10 Apr '02

10 Apr '02

Hello, First of all I am new to Python and Zope coming from Java/PHP. I am creating a simple Python script that displays a random image (image1, image2, image3....). All I want to do do is generate a random number which is concatenated to the end of the context attribute similar to this example in PHP: $randomNumber = ***some random number*** return context.{'image'.$randomNumber} Is this possible (and easy) in Python? Thanks, Michael LaPera

DTML Question
by Michael 10 Apr '02

10 Apr '02

I use the following snippet of code in one way and it works fine. I try to use another way and nothing happens, I just get a blank screen. The paths is correct. <dtml-with "sites.specifics"> <dtml-if "target_url() == 'my_url'"> <dtml-var site_url> <dtml-var site_logo> <dtml-var site_name> <dtml-var site_acronym> </dtml-if> </dtml-with> This seems to work fine and it will pull up all the objects in the folder. But when I try to get this to work with my Contacts Product or Folder, nothing happens. I've tried to access my Catalog: <dtml-with "Contacts.Catalog"> <dtml-if "contact_tracking() == '100467893'"> <dtml-var contact_fname> <dtml-var contact_lname> <dtml-var contact_street> <dtml-var contact_city> </dtml-if> </dtml-with> But nothing happens. I tried to access my entries folder also: <dtml-with "Contacts.entries"> <dtml-if "contact_tracking() == '100467893'"> <dtml-var contact_fname> <dtml-var contact_lname> <dtml-var contact_street> <dtml-var contact_city> </dtml-if> </dtml-with> Can somebody give me a hint as to what I'm doing wrong here, besides staying up all night:-( Thanks, Michael
