Caching/http-acceleration and proxying Zope-served content
by sean.upton＠uniontrib.com 09 Jan '01

09 Jan '01

I have a question, for anyone experienced in working with Zope and caching proxies: I'm setting up a load-balanced server farm that has nodes that will run Apache and proxy (via mod_proxy) to ZEO clients running ZServer. This farm is routed (both ways) through a layer 4 load-balancing appliance, and all these boxes (both nodes and the balancer) are sitting inside a DMZ with private IP addresses. The public world will access these servers via a firewall box running transparent proxy (actually, I guess, similar to squid's http_accel mode; the semantics here are a bit tricky, as it's more of a inverse trans-proxy). Between Apache and Zope, there would be several virtual hosts, and I'd be using the SiteAccess product. It gets a bit tricky in that I need to access several different virtual hosts inside the DMZ (one for the ZEO farm, and another for a dedicated CGI-based ad server on another box) via the proxy. A more detailed (ascii art) diagram of what I am trying to do, is at http://209.132.8.98/server_ascii_art.txt My question is this: does anybody have any thoughts on the merits of Squid (http accelerator mode) versus Apache/mod_proxy in terms of caching, virtual hosts, and the like when working with Zope sites? Any big pitfalls to this kind of setup with Zope sites? Also, somewhat related, is: if anybody knows if Squid can even handle multiple virtual hosts running on different boxes? Or is squid not suitable for an inverse-proxy running on the border of a DMZ containing more that a single host? I'd really appreciate anyone's thoughts. Once I get this thing working, I'll likely end up writing a howto regarding how I did it, as this seems like a useful setup for a high-volume, heterogeneous (not ideal, but reality), production media site running Zope (and other legacy CGI apps / static content as well)...

ZCatalog and 'fuzzy logic'
by Morten W. Petersen 09 Jan '01

Is there anyone who could try to give an estimate of how long it would take to add fuzzy logic (regexp-like) searching capability to the ZCatalog? And reasoning as to why would be appreciated. ;) -Morten

Unidentified problem with SiteRoot
by Kelvin Cheong 09 Jan '01

09 Jan '01

Hello all, I have a problem which i suspect is site root's problem. The scenario, I have folders F1, F1a and F2, where F1a is a child of F1 and F2 is on the same directory level as F1. Also F1 and F2 have their own DB-connections DB1 and DB2 respectively, which have the exact same properties/connection. Then... 1) i placed a SiteRoot in F1, 2) then removed it, 3) copied & pasted F1a into F2, 4) renamed the F1a in F2 to F2a, 5) create a SiteRoot in F1 again, 6) and create a SiteRoot in F2 i've also tried restarting Zope between steps 2 and 3 Then it seems that the ZSQL Methods in F2a are referring still referring to the MySQL DB connection in F1. I've tested it many tiems with otehr folders aswell, and it seems that they're all reacting the same way. In other words, it seems like once a SiteRoot has been created in the folder, the DB connections stick to it. I've also tried the "Undo" from Zope's Management Interface, but to no avail. Perhaps my intuition of all this is wrong altogether. Anyone out there experienced the same problem, or have any solutions to this problem? Thanks Zopistas, amoebia

How to set a REQUEST variable inside a PythonMethod?
by Juan Carlos Coruña 09 Jan '01

09 Jan '01

Hello all! I have another question related with PythonMethod. This time I tried: REQUEST.update({'NoRows': 4}) and I tried: REQUEST['NoRows'] = 4 and I tried: REQUEST.set('NoRows', 4) but without success. (I passed the REQUEST object in the parameter list.) Anybody has set a REQUEST variable from inside a PythonMethod?

Steve, I think that may be what I'm missing. I don't see any way to add MarketItems from within the marketItems folder. The only form is ShopperMarketItemAddForm which doesn't seem to let me actually add MarketItems and always returns the following message "You must be validated for submission first..." no matter who I am logged in as (Zope manager or EMartket Shopper). Is a ShopperMarketItem the same as a MarketItem? I'm aware that more effort is being put into 0.2 for obvious reasons so I don't want to take up too much more of your time. I just really don't need the power of the ZPattern version nor do I want to waste time trying to get ZPatterns installed. I have tried a few of the other e-commerce products and EMartet seems to have the best mix of simplicity and power. Thanks!!

I did a blunder now I can't access zope...
by Dany Rioux 09 Jan '01

09 Jan '01

Hello... No, I'm not proud of myself. Anyway, here's what happened. I installed a product in the root and when it asked me about the base url, I typed an URL that isn't "attached" to zope, now I find myself trying to connect to zope as I would usually do but only receive "The requested URL /manage was not found on this server." I know this message is generated by Apache but even after changing Apache's configuration so the sub-domain that is refered is sent to zope, I still get that message sent by apache for a 404. If I remove the port number, I am getting the "normal" site (which is an apache only site). Now, from what I can guess, I have to remove the part I added as the base url in the Data.fs but I don't know how to do that. Sorry, I can't explain it better than that... Any suggestions except reinstalling? TIA! Dany ---.oo0O--------------O0oo.-------- Dany Rioux UnderSoft Inc.

RE: [Zope] Python Scripts in 2.2.x
by Mayers, Philip J 09 Jan '01

Oops, ignore that - copied the wrong error from the window (from an earlier attempt). The *real* error was that I was running zpasswd as root with a umask of 077, which of course meant the webserver and Zope couldn't read the resulting file. So, the LoginManager product appears to work, but the problem now is when I try to add a LoginManager to a folder, I get a NameError for 'path', with a traceback: Traceback (innermost last): File /usr/local/Zope23/lib/python/ZPublisher/Publish.py, line 222, in publish_module File /usr/local/Zope23/lib/python/ZPublisher/Publish.py, line 187, in publish File /usr/local/Zope23/lib/python/Zope/__init__.py, line 221, in zpublisher_exception_hook File /usr/local/Zope23/lib/python/ZPublisher/Publish.py, line 171, in publish File /usr/local/Zope23/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: addLoginManager) File /usr/local/Zope23/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: addLoginManager) File /usr/local/Zope23/lib/python/App/special_dtml.py, line 120, in __call__ (Object: addLoginManager) (Info: /usr/local/Zope23/lib/python/Products/LoginManager/addLoginManager.dtml) File /usr/local/Zope23/lib/python/DocumentTemplate/DT_String.py, line 528, in __call__ (Object: addLoginManager) File /usr/local/Zope23/lib/python/DocumentTemplate/DT_In.py, line 633, in renderwob (Object: UserSourcesMetaTypes(this())) File /usr/local/Zope23/lib/python/DocumentTemplate/DT_Util.py, line 331, in eval (Object: UserSourcesMetaTypes(this())) (Info: UserSourcesMetaTypes) File /usr/local/Zope23/lib/python/ZPublisher/HTTPRequest.py, line 772, in __getitem__ NameError: (see above) Regards, Phil +----------------------------------+ | Phil Mayers, Network Support | | Centre for Computing Services | | Imperial College | +----------------------------------+ -----Original Message----- From: Mayers, Philip J Sent: 09 January 2001 10:01 To: 'Bill Anderson' Subject: RE: [Zope] Python Scripts in 2.2.x No, I'm afraid not: Traceback (innermost last): File "/usr/local/Zope23/lib/python/OFS/Application.py", line 405, in import_products product=__import__(pname, global_dict, global_dict, silly) File "/usr/local/Zope23/lib/python/Products/LoginManager/__init__.py", line 1, in ? import LoginManager, LoginMethods, UserSources File "/usr/local/Zope23/lib/python/Products/LoginManager/LoginManager.py", line 8, in ? from Products.ZPatterns.Specialists import Specialist File "/usr/local/Zope23/lib/python/Products/ZPatterns/__init__.py", line 1, in ? import Rack, Specialists, Customizers, AttributeProviders, SheetProviders File "/usr/local/Zope23/lib/python/Products/ZPatterns/Rack.py", line 9, in ? from DataSkins import DataSkin File "/usr/local/Zope23/lib/python/Products/ZPatterns/DataSkins.py", line 1, in ? from DynPersist import DynPersist ImportError: No module named DynPersist Regards, Phil +----------------------------------+ | Phil Mayers, Network Support | | Centre for Computing Services | | Imperial College | +----------------------------------+ -----Original Message----- From: Bill Anderson [mailto:bill@libc.org] Sent: 09 January 2001 04:42 To: Mayers, Philip J Subject: Re: [Zope] Python Scripts in 2.2.x Mayers, Philip J wrote: > I need to use LoginManager, which doesn't seem to work with 2.3, It does after a minor modification... http://www.egroups.com/message/zope/47172 Bill Anderson

Acquisition: DTML Methods vs Documents
by Oleg Broytmann 09 Jan '01

09 Jan '01

Hello! Can anyone here explain clearly what is the difference between DTML Methods and DTML Documents regarding acquisition? Well, in simple cases I think I understand it. When I call a Method through the web, it use dynamic (based on current URL) acquisition path. A Document uses static (based on its position in ZODB) path. But what if I want to look a bit deeper? What are acquision paths for a Method called from a Document, not directly from the web? I beleive when a Document called from a Method it always uses static acquisition path. But what about a Method called from a Document? It seems my Methods stopped using dynamic paths and use static paths, provided by its callee. Right? Let's see a running demo. The site http://phd.russ.ru/pcgi/TEST/ constructed as follows: /TEST - folder index_html - standard DTML Document with default content standard_html_header - DTML Method standard_html_footer - DTML Method 2 - folder, empty Both folders /TEST and /TEST/2 have a property "foobar". In /TEST its value is "First test!", in /TEST/2 - "This is SECOND test." standard_html_header show the property with <dtml-var foobar>. When I call standard_html_header directly through the web, it acquires foobar using dynamic acquisition path: http://phd.russ.ru/pcgi/TEST/standard_html_header show foobar from root (/TEST) http://phd.russ.ru/pcgi/TEST/2/standard_html_header show foobar from /TEST/2 But then I call standard_html_header from DTML Document index_html: http://phd.russ.ru/pcgi/TEST/index_html show foobar from root (/TEST); exactly as I expected, no problem http://phd.russ.ru/pcgi/TEST/2/index_html WOW! It show foobar again from root, not from /TEST/2! standard_html_header acquires using static path provided by index_html! Is it normal and intended behaviour? If it is, how can I "solve" my problem? (I want to acquire different properties in standard_html_header, but call standard_html_header from different DTML Documents).
