When to use trusted-proxy?
by Florian Lindner 14 Oct '03

14 Oct '03

Hello, should I set the trusted-proxy in Zope 2.7 to 127.0.0.1 when using Apaches Proxy module? Should I also set it, when using only RewriteRules and no ProxyModule? Thanks, Florian

ANNOUNCE: Pound - reverse proxy and load balancer - v1.5
by Robert Segall 14 Oct '03

14 Oct '03

This is to announce the release of Pound v1.5. Changes in this version: - support for sessions by Basic Authentication: "Session BASIC" parameter added - stringent syntax checking of request. - user-defined request character set(s): new parameters CSsegment, CSparameter, CSqid, CSqval - option to limit the request size: parameter MaxRequest - single log function rather than #ifdefs. - added LogLevel 4 (same as 3 but without the virtual host info). - added HeadRemove directive (allows to delete a header from requests). - location rewriting on redirect (codes 301, 302, 303, 307): the content is changed to reflect the location for Pound rathre than the back-end - some bug fixes and speed improvements The software is at version 1.5 (production quality). Further testing (especially under heavy loads), improvements and suggestions are welcome. What is Pound (from the Web page) - a reverse-proxy: it passes requests from client browsers to one or more back-end servers. - a load balancer: it will distribute the requests from the client browsers among several back-end servers, while keeping session information. - an SSL wrapper: Pound will decrypt HTTPS requests from client browsers and pass them as plain HTTP to the back-end browsers. - an HTTP/HTTPS sanitizer: Pound will verify requests for correctness and accept only well-formed ones. - an HTTP/1.1 to 1.0 proxy. - a fail-over-server: should a back-end server fail, Pound will take note of the fact and stop passing requests to it until it recovers. - a request redirector - it will pass client requests to separate groups of servers, based on required URL and the presence or absence of headers (pattern matching) Pound was specifically developed to serve as a front-end for multiple instances of Zope running on top of a common ZEO storage, but can be used with any other web server. A patch for the Python source of z2.py is available as part of the distribution to allow using Pound's SSL capabilities. Pound is currently in use in several medium to large volume sites and seems to be holding up quite well: largest reported site does about 5.5 million requests per day, peaking at over 450 requests per second. The speed is well superior to other, equivalent solutions, the configuration is much simpler and the necessary resources (CPU, RAM, disk) are much, much lower. Pound is distributed under the GPL. For further information, download, etc. please see http://www.apsis.ch/pound Pound now has its own mailing-list - just send a message to pound-subscribe(a)apsis.ch in order to join. Enjoy and let me know how it works for you. -- Robert Segall Apsis GmbH Postfach, Uetikon am See, CH-8707 Tel: +41-1-920 4904

FTP support
by Alexis Roda 14 Oct '03

14 Oct '03

Hi again, I have a calendar product (Calendar), a container for CalendarItem. I want the calendar instances to have a folder for template storage, so the user can customize some views of the calendar: calendar_instance | + template_folder | | | + template_1 | + calendar_item_1 | + calendar_item_2 In Calendar.__init__ I do: def __init__(self, id, title = "") : CalendarBase.__init__(self, id, title) # create a folder tmpl = Folder(id='templates') # add it to the calendar self._setObject('templates', tmpl) # add some default "templates" to the folder tmpl.manage_addDTMLMethod(...) My problem is that I can't access the templates folder contents with FTP. With emacs I get a "550 Could not list directory" error. All three classes inherit from SimpleItem.Item, Calendar and CalendarBase inherit from ObjectManager. AFAIK Folder is FTP aware. What I'm doing wrong? Thanks in advance. -- //// (@ @) ---------------------------oOO----(_)----OOo------------------------ Los pecados de los tres mundos desapareceran conmigo.

copy paste support
by Alexis Roda 14 Oct '03

14 Oct '03

Hi, I'm writing a product and I have a little trouble with copy & paste support. My product defines three clases: ZSimpleMenu, ZSimpleMenuItem and ZSubMenuItem. The first one is a container for the other two. The last two have no sense outside a ZSimpleMenu, so I don't want them to be listed on the "global" add list, only on the ZSimpleMenu add list. In order to acomplish this I have registered (registerClass) only ZSimpleMenu, and store on ZSimpleMenu.all_meta_types the meta types of the two Z*Items. all_meta_types = ( {'name': 'Menu Item', 'action': 'manage_addMenuItemForm' }, {'name': 'Submenu Item', 'action': 'manage_addSubmenuItemForm' }, ) This does work, I can add objects as expected, but copy & paste don't work for Z*Items. When I try to copy/paste a ZSimpleMenuItem (id == m0100) within a ZSimpleMenu I get a "The object m0100 does not support this operation" error message. Copy/paste does work from ZSimpleMenu. All three objects inherit from OFS.SimpleItem.Item so I suspect that the problem is related to the way I'm registering the classes. What's the right way to register the Z*Items so I can copy & paste them, and they don't appear on the global add list?

zope and python classes
by Ted holden 14 Oct '03

14 Oct '03

If I could get the following to work, I'd have all the state maintenance I'd ever need. I have a file called bearcl1.py with the lines: class bearcl1: gstr = "a wet bird never flies at night" def getgstr(self): return self.gstr def setgstr( self, InputStr ): self.gstr = InputStr and a file called __init__.py with the lines: from bearcl1 import bearcl1 def initialize(context): """ Register base class """ context.registerBaseClass( both saved in a subdir called: /home/bear/zope/lib/python/Products/bearclxpt1/ and have created a product called bcl1 with a zclass called bzcl1 which subclasses bearcl1 and CatalogAware. Moreover, the class bzcl1 now shows up on my ADD list when constructing web pages so that I can have an object called bz1 of the class bzcl1 and a dtml page in the same folder and the dtml page contain a line like: <dtml-var bz1.getgstr > which looks like it ought to work ( and produce 'a wet biord never flies at night' on the resulting page ) but doesn't. Again, if I could get that much to work I'd basically be home free. I'd appreciate any suggestions. Ted Holden

including a dtml method through a variable
by Declan Shanaghy 13 Oct '03

13 Oct '03

With reference to the usual dtml-var to include a dtml-method in another page. i.e. <dtml-var page_dtml_widget> How is it possible to do this dynamically? Lets say in some pyhton script i execute a line like this: if a: REQUEST.set("widget", "page_dtml_widget1") else: REQUEST.set("widget", "page_dtml_widget2") Later on in the dtml method, how can i use that variable for a dynamic include? <dtml-var widget>... ...Obviously doesnt work, it just prints out the value of the variable. After much head scratching i still cant get around this. Any suggestions anyone?

RE: [Zope] including a dtml method through a variable
by Derek S. Wilson 13 Oct '03

Generally, variables return values, and you would just keep the same variable name and return different values. If you're not wanting to return values, but return something else, then don't use dtml-var. You'd want to do an eval or something else.

printing documentation from zope.org?
by Jeff Rankin 13 Oct '03

13 Oct '03

This may sound silly, but I'm trying to print documentation (specifically the ZPT reference) from 'The Zope Book' at zope.org, but I only get the first page. Does anyone else have this problem? Is this a function of the print stylesheet or something? W. Jeffrey Rankin Lead Web Application Developer O'NEIL & ASSOCIATES, INC. http://www.oneil.com 495 Byers Rd.
