UserDb extensions

Hey zopeists - I've already sent a note to the DC guys about this, but they're all busy having fun at the Expo, so I thoungt I'd let the rest of you know, as well. I'v been using the USerDb unsupported product, and like it. However, I'v been bothered by seeing my users cleartext passwords in the db, so I added crypt hashed storage to the UserDb product. This will allow the use of unix 'passwd' style passwords (also used by apache for .htpasswd files) in the database. It also gives a modicum of security if you db backend is on a different machine from the Zope install, so the passwords don't travel around in the clear in the SQL queries. Of course, the biggest benfit is my not having to cringe when I see the bad passwords people chose in the database ;-) If anyone wants the patches, I can supply them. I assume it'll show up in the unsupported or contrib downloads at www.zope.org, once they get back. This requires the python crypt module. My Win32 install seems to have included it automagically. I had to copy the cryptmodule.so from my system python install into my Zope specific one to get in to work on Linux. Ross P.S. A useful script, for converting an exisiting sql db: as written, it takes a whitespace seperated file of username,password pairs and spits out sql statements to update the passwords (this version works with Postgresql: you may need to flavor by changing the ; or something to work with other dbs) from string import split,letters from crypt import crypt from whrandom import choice import fileinput for line in fileinput.input(): name,password=split(line) print "update users set password='%s' where username='%s';" % (crypt(password,choice(letters)+choice(letters)),name) -- Ross J.

trees

How I make #tree if objects for #tree stored in database? for example - has two tables: TFolders and TObjects Each TObject found in one TFolder. How I make this #tree without making objects in Zope database? Obviously using only DTML.

Zope & Apache
by Chuck Mead 24 May '99

24 May '99

I'm trying to run Zope with Apache... but I can't get into "manage". This is in httpd.conf: # Zope configuration maps /Zope/ to the Zope.cgi CGI script RewriteEngine on RewriteCond %{HTTP:Authorization} ^(.*) RewriteRule ^/Zope/(.*) /home/httpd/cgi-bin/Zope.cgi/$1 [e=HTTP_CGI_AUTHORIZATION:%1,t=application/x-httpd-cgi,l] Note: the rewrite rule is all one line! Zope.cgi is in /home/httpd/cgi-bin/ and it works because I get the login screen! When I enter the username and the password it rejects it and doesn't allow me access. It says "No Authorization header found". I'm running: apache_modperl-1.3.6-1.19-1 on Red Hat Linux 5.1. The $zope_home/var directory and the $zope_home/access file are both set UID and GID nobody and the access file is readable by nobody and root. Can somebody hit me with the clue-bat?

PO'd
by Chuck Mead 24 May '99

You know this is really a major pain in the butt! I just saw Zope for the first time at LinuxExpo and it rocks... so here I am... I've installed it for Apache and E-V-E-R-Y-T-H-I-N-G works except for the manage screen... that fails everytime! Why... I've done everything it says in the doc's including that infernal WEBSERVER.txt file and then I tried a whole pile of stuff from the archives of this list and none of it works... Surely somebody, somewhere has had this problem and fixed it and is capable of explaining the process required to make this work... Anybody?!?

Zope vs CVS (Re: [ZDP] OpenContent issues)
by Simon Michael 24 May '99

24 May '99

I wrote: > CVS is used to provide & control access to the files. We also have the option to use zope to provide distributed access. This would be a good public demonstration of zope power. Some advantages of using CVS: - most powerful version control & logging of who did what - widespread & standard - excellent tools like cvsweb ready-made - supports working offline & merging with master copy Some advantages of using zope: - demonstrates zope to potential users - simple through-the-web authoring - CVS is too tricky for many - advanced functionality can be added if needed - learning exercise I have been debating this zope/cvs issue myself, in regard to an intranet which I maintain which currently uses CVS to allow distributed authoring. Switching to zope will allow me to provide an easier interface & more features, but I don't want to give up the advantages of CVS either. I haven't thought of a good way to combine the two. Question: has the latest webDAV support resolved this dilemma, or will it soon ? Regards, -Simon

Zope 1 databases will not be compatable with it. There will be a conversion script supplied with (probably) the beta release of Zope 2.

This means that all of your python threads contend for this global lock while they are running. Pyhton itself will nicely preempt your threads and they will flow smoothly, and there are sections of Python where it is safe for two threads to run conccurently, but you will not notice an Nfold increase of speed for N processors. I think this is being addressed in the Python community. I have no idea, but I've heard mention that python 2.0 will not have the global lock. Don't quote me though. The threading in ZServer is still a big win, however, because the internal Python thread switching is much more efficient then the external OS process/thread context switching. With Zope 2.0 and ZServer, one request will not block all other requests because Pyhton will nicely switch between Zope threads even in the middle of a request. This model will give you even better performance than the Apache multi-process model, which suffers a very expensive context switch for each Apache process. -Michel > > I am working on a tight budget so for an example here are a > few options. > > single PII 400 or 450 or K6-3 450 > > or > > dual PII 300 or 333 > > or > > dual PPro 200 (talking to a friend who might have one available) > > > Jimmie Houchin > > _______________________________________________ > Zope maillist - Zope(a)zope.org > http://www.zope.org/mailman/listinfo/zope > > (For developer-specific issues, use the companion list, > zope-dev(a)zope.org - http://www.zope.org/mailman/listinfo/zope-dev ) >
