Common GenericUserFolder problem ...
by Darran Edmundson 04 Mar '00

04 Mar '00

Hi All, I bashed my head against GenericUserFolder for three hours tonight trying to get the simplest of scenarios up and running - no luck so I'm turning to the list for help. My exact problem shows up in the archives with advice from Zen: >>got the simple login screen. I entered the values 'jorge' for the username >>and 'secret' for the password. When I pressed Ok, I didn't see the >>index_html file for the folder, instead I got the login screen once >>again. Can someone help me out with some ideas on what I might have done >>wrong (or not done at all?) >Sounds like you havn't granted permission for user jorge to view the >documents. Simple way to test this is to edit userRoles so that >jorge is a member of the Manager role. I've done both this and explicitly returning _.int('1') in the userAuthenticate method. Same problem. Turning debug on in the GUF source yields: 2000-02-29T13:30:46 PROBLEM(100) GUF URL is http://127.0.0.1:8080/Test2 in validate ------ 2000-02-29T13:30:46 INFO(0) GUF Successful authentication for user ost124 (http://127.0.0.1:8080/Test2/acl_users) ------ 2000-02-29T13:30:46 PROBLEM(100) GUF gufid = ------ 2000-02-29T13:30:46 PROBLEM(100) GUF URL is http://127.0.0.1:8080/Test2 ------ 2000-02-29T13:30:46 PROBLEM(100) GUF Returning ost124 from http://127.0.0.1:8080/Test2/acl_users validate (roles=('Anonymous', 'Manager')) ------ 2000-02-29T13:30:46 PROBLEM(100) GUF URL is http://127.0.0.1:8080/Test2 in validate ------ 2000-02-29T13:30:46 PROBLEM(100) GUF Failed to authenticate with http://127.0.0.1:8080/Test2/acl_users - crawling up ------ 2000-02-29T13:30:46 PROBLEM(100) GUF Failed Authentication with http://127.0.0.1:8080/acl_users As the user is explicitly given the manager role which has all possible permissions checked, how can I possibly fail authentication? Any help is much appreciated. Cheers, Darran.

FYI: large files & linux.
by ethan mindlace fremen 04 Mar '00

04 Mar '00

Zopistas, I was trying to get large file support on linux. I succeeded, but only partially. Steps: 1. Download and install a kernel greater than 2.3.27. It has the large file patch built in. 2. Reformat ext2 partition with 4k blocks: mke2fs /dev/hdaX --block-size 4096 the maximum filesize for ext2 depends on the blocksize: with 4k blocks, it's 1TB. 3. Use Glibc 2.1.13-5 from debian potato. unknown whether 2.1.12 from the gnu site is sufficient. 4. compile python 1.5.2 like so: CFLAGS="-D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64" OPT="-O2 $CFLAGS" \ ./configure --with-threads 5. Now you can make files up to 4096 MB in size. Why no bigger? I have no idea. For me, at least, it means 1/2 as many zopes. Optional step: Wait. In a few short months Linux should handle large files natively. -- ethan mindlace fremen - mindlace(a)imeme.net good design is as close as I want to get to ideology.

Javascript for Zope project
by Sin Hang Kin 04 Mar '00

Is this possible? On zope site we could collect links to opensource / free javascript. On later stage, we could examine them and make them adapt them to zope. Any one interested?

Assorted Zope problems
by Ed Thomson 04 Mar '00

04 Mar '00

Hello- I've been trying to get our existing Zope server (previously with ZServer handling http) under Apache. Here are some problems I ran into: 1. My biggest problem was that Zope uses the SCRIPT_NAME environment variable to construct it's notion of the base URI. Unfortunately, SCRIPT_NAME gives the actual script name, not the URI. So if you do a ScriptAlias, or any rewriting inside Apache, this isn't necessarily valid. An adequate solution seems to be to change PYTHONHOME/lib/python/ZPublisher/HTTPRequest.py line 211, to use DOCUMENT_URI instead of SCRIPT_NAME. 2. I couldn't get Apache with FastCGI and Zope working reliably. On about 1% of requests, garbage would be returned, resulting in random broken images or pages full of gibberish. This is with the Oct 06 snapshot of FastCGI, compiled into Apache-1.3.12. Anyone else seen anything like this? Ed

Zope DHTML and XHTML : Moving things to the Client-side
by Sin Hang Kin 04 Mar '00

04 Mar '00

I think it worth to encourage zopelist to move more things to the client-side by modify a Zope fresh installation. I found out there are many things hard-coded in python or dtml in zope's source. There are some things which can be do better in the client side. For example, there were many dynamic folder tree writen in javascript which can be more responsible than the zope tree tag (which the change of the tree state require the help from server). I would like to urge zopelists to explorer the client side authoring which could actually give zope a dramatically change. 1. Remove those hard-coded parameters from the source and placed them in the folder tree as attributes which can be modified or overwrited by manage interface and acquisition. 2. Define the basic css (which zope.org have one) as default elements with the fress zope install. 3. Make the current Zope tag comply with xml standards : they should end with /> or accept an end tag. 4. Collect open-source javascript codes and convert them into zope products (like tree).

PostgreSQL money weird problem
by Cesar A. K. Grossmann 04 Mar '00

Hi, I'm with a weird problem with a report from a SQL database. I have a field of type 'money', and every time I use it in a SELECT query, it returns 0.00, doesn't matter the actual value of the field (in the example bellow - the 'test' of the query -, the field Valor is of type 'money'): Id | Idcliente | Data | Valor 1 | 11 | 03-03-2000 | 0.0 2 | 11 | 03-03-2000 | 0.0 3 | 11 | 03-03-2000 | 0.0 SQL used: select * from compras where idcliente=11 Running the same query on the interactive client, gives the value of money: credito=> select * from compras where idcliente=11; id|idcliente| data|valor --+---------+----------+-------- 1| 11|03-03-2000|R$50,00 2| 11|03-03-2000|R$150,00 3| 11|03-03-2000|R$15,00 (3 rows) I'm using Zope 2.1.2, ZPyGreSQLDA, and PostgreSQL 6.4.2, running in a Conectiva Linux 4.0 (kernel version is 2.2.5). The definition of the class compras is: Table = compras +--------------+----------------------------------+-------+ | Field | Type | Length| +--------------+----------------------------------+-------+ | id | int4 not null default nextval('c | 4 | | idcliente | int4 | 4 | | data | date | 4 | | valor | money | 4 | +--------------+----------------------------------+-------+ Indices: compras_id_key compras_pkey TIA -- Cesar A.

Logging users in Zope 2.x (second try)
by Hannu Krosing 04 Mar '00

04 Mar '00

How should I configure logging to get usernames into Z2.log I first hoped to get it from Apache's access_log, but it saves username only when doing user authentication itself. Then I thought that Zope at least would log it and migrated the site to Zope 2.1.3 to get logging support. Unfortunately it does still not log usernames and I have not found the place where I could turn it on. Also the format is buggy: Apache access_log: 193.40.215.135 - - [11/Feb/2000:08:29:55 +0200] "GET / HTTP/1.1" 200 2673 Zope Z2.log 127.0.0.1- - [11/Feb/2000:19:04:46 +0300] "GET /misc_/OFSP/dtmlmethod.gif" 200 1000 the bug being the missing space after the IP address. what I was hoping for would have looked like: 127.0.0.1 - superuser [11/Feb/2000:19:04:46 +0300] "GET /manage" 200 1000 ------- Hannu

Hooking into traversal
by Andrew M. Kuchling 04 Mar '00

04 Mar '00

I want to write an object that can be traversed by ZPublisher. The goal is so I can write URLs like thingyForwarder/45/display, to get an object corresponding to thingy #45, and call its display() method. What's the Zope Zen way of doing this? Implement an __of__ method for acquisition? Implement a __bobo_traverse__ method? Make thingyForwarder a Folderish object and implement all the folder methods? -- A.M. Kuchling http://starship.python.net/crew/amk/ "Wet", said he. Classics was his subject, and he sometimes affected a classical simplicity in social conversation. -- Robertson Davies, _Tempest-Tost_
