- Pb with Apache (authentication)
by Ronan BARZIC 31 Dec '98

31 Dec '98

Hello, I've a problem with Zope 1.0.9 (source distribution) with authentication. I'am using Apache 1.2.6 from a RedHat 5.1 distribution with the standard configuration files plus the the rewrite Rule in httpd.conf : RewriteEngine on RewriteLog /etc/httpd/logs/rewrite.log RewriteLogLevel 9 RewriteCond %{HTTP:Authorization} ^(.*) RewriteRule ^/Zope/(.*) /home/httpd/cgi-bin/Zope.cgi/$1 [e=HTTP_CGI_AUTHORIZATION:%1,t=application/x-httpd-cgi,l] For testing, i've installed Zope under the /home/httpd/Zope-1.9.0-src and a link with /home/hhtpd/Zope.lnk Zope.cgi is in the cgi-bin directory The URL //mymachine/cgi-bin/Zope.cgi gives the welcome page The URL //mymachine/cgi-bin/Zope.cgi/manage asks the superuser name and the password but it faills The URL //mymachine/Zope/manage asks the superuser name and the password but it faills. The log for the rewrite rule seems to be correct (and it works...) httpd runs as nobody. access file is owned by nobody with read and write access. ls-l var gives : total 26 -rw-rw-rw- 1 nobody nobody 10780 Dec 30 17:22 Data.bbb -rw-rw-rw- 1 nobody nobody 7789 Dec 30 17:11 Data.bbb.in -rw-r--r-- 1 nobody nobody 9 Dec 30 17:22 Data.bbb.trans drwxrwxrwx 3 nobody nobody 1024 Dec 30 17:21 gadfly -rw-rw-rw- 1 nobody nobody 3135 Dec 30 17:21 pcgi.log -rw-rw-rw- 1 nobody nobody 4 Dec 30 17:22 pcgi.pid srwxrwxrwx 1 nobody nobody 0 Dec 30 17:22 pcgi.soc ls -l access gives : -rwxrw-rw- 1 nobody nobody 16 Dec 30 18:12 access Thank you Ronan BARZIC barzic(a)worldnet.fr

- OK enough fo the file tree thing
by Christopher G. Petrilli 31 Dec '98

31 Dec '98

<FLAME> Maybe it's just me, but there seem to be a lot of people who don't "get" why ZOPE is what it is, and are asking for it to be something it isn't. It's an OBJECT publishign system, not a file publishing system. If all you want is a bunch of files sitting in a directory that are scripted, use PHP or some such... you'd loose all inheritance, attributes and encapsulation, but that is what it sounds like you want... We don't need to waste a TON of bandwidth trying to ask why ZOPE is something it can't be... it can pretend to be a few things, but after a point it's a "OBJECT PUBLISHING ENVIRONMENT", which has great benefits and some paradigm shifts... If this isn't what you need/want, move on, keep going. If you can use ZPublisher without the POS, go for it, that is the point is it not? But if you can't use ANY of it because of the paradigm, then it's time to move on. This is like sitting around complaining to Guido that Python really needs to be Perl, and why can't he make it Perl... Paradigm change? Get it? FWIW, my last major web project was all driven out of Illustra without a single file in the file system, anywhere, and we had great success, and none of these problems. We'd have built it on Zope if it'd existed, or we'd known about Principia. My complaints about Zope are almost all documentation related... </FLAME> My $1.45 Chris -- | Christopher Petrilli | petrilli(a)amber.org

- Requirements for a project development system
by Curtis Galloway 31 Dec '98

31 Dec '98

I realize that my previous message was slightly inflammatory. In an effort to be constructive, here is my minimum set of requirements for any project development system: 1. The source code should be represented as plain ASCII files. 2. All required actions must be automatable. Corollaries to requirement 1: you can edit source files with your favorite editor, diff them, and store them in your favorite source code control package. By "source code" I mean all the information you create for your project: C, Python, HTML, documentation, whatever. If there is meta-data that is required to make your project work, it should be stored in a human-readable form as well. An example of this might be permissions on files, which would be stored in the form of a Makefile rule that sets the permissions.. Corollaries to requirement 2: you must be able to build and maintain your project with command-line tools. Being able to use a GUI or a web page to do things is great, but there is no substitute for the UNIX way. Windows NT is a good counter-example to this rule. Here are some examples of project tasks that are facilitated by these basic two requirements: - I want to be able to take a snapshot of my whole project that I can roll back to at a future date. - I want one team of people to work on part of the project independently without clobbering what another team is doing. - I need to look at the diffs between yesterday's version of the project and today's version to figure out what person X did. - I want to set up an automated task to check out the latest version of the project from source control and build it on a test machine. Having said all this, there are times when I break my own rules. I am using a GUI builder right now that creates a binary file describing the UI component layouts for a window. I'd rather it represented the data in an ASCII format, but it's sufficiently useful that I'll put up with it. Also, each window is stored in a separate file, so that tends to limit the possibility of two people needing to change the same file at the same time. Your mileage may vary, of course. But I have found these principles to be useful. --Curtis

- Copying Zope objects programmatically
by A.M. Kuchling 31 Dec '98

31 Dec '98

Continuing on my channeling, I'm now trying to let users enter a selected ID; a folder named with that ID would then be created and set up. Creating the folder in DTML is easy:  I can even set a property on the newly created folder:  (Incidentally, these expression lines are getting awfully long. Is there any way to insert newlines in them?) However, I can't figure out how to create a new index_html object whose content is a duplicate of another default object; the third argument to the manage_addDocument() is never right.  _['default_user_page'].data doesn't work. str(_['default_user_page']) creates the page, but it also replaces < with <, so the DTML on the resulting page doesn't work. How do you get the contents of the Document object without it being escaped? Or am I barking up the wrong tree? Should this sort of thing be implemented as an ExternalMethod? -- A.M.

- namespace problem
by richard.jones＠fulcrum.com.au 31 Dec '98

31 Dec '98

The following DTML does not work:  <p>foo found!   <p>foo inserted!   It barfs with a NameError on foo. If I change the #call to a #with and use that to enclose the #var foo, then it works. I'd like to suggest that the description of the _.namespace function in the DTML reference include the return value (ie. "it returns a new namespace to be used in a #with" or somesuch). Given that the #call and _.namespace combination aren't going to do what I want to do, how can I do it? I've also tried REQUEST.set() but couldn't get that to work at all. Richard

- Cryptography...
by Magnus Lie Hetland 31 Dec '98

31 Dec '98

I don't know if you guys have seen Andrew K's page on Cryptographic Curiosities... But it shouldn't be too hard to include for instance the RSA algorithm in Zope, when it can be expressed in four lines of Python: #!/usr/local/bin/python from sys import*;from string import*;a=argv;[s,p,q]=filter(lambda x:x[:1]!= '-',a);d='-d'in a;e,n=atol(p,16),atol(q,16);l=(len(q)+1)/2;o,inb=l-d,l-1+d while s:s=stdin.read(inb);s and map(stdout.write,map(lambda i,b=pow(reduce( lambda x,y:(x<<8L)+y,map(ord,s)),e,n):chr(b>>8*i&255),range(o-1,-1,-1))) According to his example, it can be used like this: echo 'Top secret message.' | rsa.py 10001 1967cb529 > ciphertext cat ciphertext | rsa.py -d ac363601 1967cb529 Fuller description can be found on http://starship.skyport.net/crew/amk/writing/crypto-curiosa.html (And just out of curiosity: Is it a crime to view this web page outside the US? ;) -- Magnus Lie Hetland www.pvv.org/arcadia <arcadia@pvv..org>

- ANNOUNCE: Product API tutorial available
by Amos Latteier 31 Dec '98

31 Dec '98

Hello Zopesters: I've finally finished the first draft of a Product API tutorial. http://www.zope.org/Documentation/Reference/ProductTutorial.tar.gz It describes in pretty reasonable detail how to build a Zope Product. The example is a polling Product. I would love feedback, since this is a pretty rough draft. Have fun! -Amos

- Zope/filesystem issues
by Amos Latteier 30 Dec '98

30 Dec '98

With all this talk about wanting to use the filesystem to store Zope objects rather than the object database, I just wanted to underscore a point that has been mentioned, but mostly passed over. Zope objects are much more than simply text files. They are Python objects--so storing them in general requires something like a pickle. Documents and Folders can be approximated with filesystem directories and text files, however, they don't capture a lot of information like Zope object properties, permissions information, etc. In addition many objects like Database Connections don't map very well to a filesystem object at all. I've been thinking about these issues while working on FTP support, since FTP uses a filesystem metaphor for communication with Zope. For example, when you FTP an object in and out of Zope, you probably won't be putting and getting the complete object. You will be most likely putting and getting the textual or binary 'content' of the object. So while being able to import and export partial representations of Zope objects to and from the filesystem is an important convenience, I see big problems with it being a complete replacement for through the web editing. -Amos

- Tabula
by Magnus Lie Hetland 30 Dec '98

30 Dec '98

Where is the documentation for Tabula? Is it indeed a standard part of Zope? Sorry if I'm being dense here... (And yes, I did find the Object Reference, but it wasn't easy to use as an introduction...) (Perhaps you should have a search engine on your site? :) -- Magnus Lie Hetland www.pvv.org/arcadia <arcadia(a)pvv.org>
