A comparison of Zope and ACS
by Kevin Dangoor 28 Apr '00

28 Apr '00

Hi, I've posted a work-in-progress doc on Zope.org that compares ACS and Zope with regards to things that I care about. I started this a couple weeks back and think that others may be interested in the opinions. If you see any factual errors (particularly if you've actually used a running ACS and I've gotten something way wrong) or have other feedback, send me a message...

RE: [Zope] A nice problem with url_quote_plus
by Chris McDonough 28 Apr '00

28 Apr '00

Actually, I don't think url_quote_plus is what you want. I think rather you need to come up with a DTML method that replaces spaces with plus signs only. You don't want to URL-quote the whole url, because when doing so, you replace colons with %3a's, etc. You don't need to do this to pass this to a redirect, and as a matter of fact it won't work at all. Here's a DTRL method 'my_space_replacer' that does that: <dtml-var "_.string.replace(unquoted_url, ' ', '+')" > And here's a method that calls it: <dtml-call "REQUEST.set('unquoted_url', 'http://www.zope.org/Howdy there')"> <dtml-call "REQUEST.set('quoted_url', my_space_replacer(_.None, REQUEST))"> <dtml-call "RESPONSE.redirect(quoted_url)"> > -----Original Message----- > From: Nbk [mailto:nbk@cyberdude.com] > Sent: Friday, April 28, 2000 6:42 AM > To: zope(a)zope.org > Subject: [Zope] A nice problem with url_quote_plus > > > Hi. > > I have the folowing code in one of my DTML method's: > > <dtml-call "RESPONSE.redirect(_.string.join([url,query],''))"> > > 'url' and 'query' are two variables passed by the REQUEST. > This work's just fine, > but with some minor :-) problems in my case.

Answer about REQUEST problems in 2.1.6 ZSQL Methods...
by Brian Lloyd 28 Apr '00

28 Apr '00

For those of you who have been struggling to figure out why references to REQUEST (like <dtml-with REQUEST>) don't seem to be working anymore on 2.1.6 installations, I think I've finally tracked it down. In lib/python/ZPublisher/BaseRequest.py, there is a section near the top: try: from ExtensionClass import Base __roles__=None class RequestContainer(Base): def __init__(self,**kw): for k,v in kw.items(): self.__dict__[k]=v def manage_property_types(self): return type_converters.keys() Note that the __roles__=None line is in a silly place - it really wants to be in the class statement: try: from ExtensionClass import Base class RequestContainer(Base): __roles__=None def __init__(self,**kw): for k,v in kw.items(): self.__dict__[k]=v def manage_property_types(self): return type_converters.keys() Note that this fix will be in the next release - in the meantime you want to make this fix to your BaseRequest.py file in your 2.1.6 installation rather than work around it by changing DTML code to pass the REQUEST explicitly.

A lot of the "common abstraction" benefits of using PAM are perhaps eclipsed by the much higher-level abstractions offered by the LoginManager product. I think the best approach would be to work with Phillip Eby and Ty Sarna (the developers of LoginManager) who are about to release an LDAP-enabled LM derivative. My guess is that writing a PAM/kerberos LM derivative will be a SMOP, given the LDAP version as a model (think, "writing an ethernet driver for Linux, for a NIC much like the 3C509").

Trees of search results
by Jason Spisak 28 Apr '00

28 Apr '00

Zopists, Is there any way to get a tree tag to render from search results so that you can "turn down" the *result* and see it's children? <dtml-in "objectValues()" size=10 skip_unauthorized reverse> <dtml-let a=sequence-item> <dtml-tree expr="a.PARENTS[1]"> <dtml-var id> </dtml-tree> </dtml-let> </dtml-in> The above code doesn't work. I'll bet it's trivial but I'm missing it. All my best, -- Jason Spisak 444(a)hiretechs.com

Re: Phil Greenspun on ACS and ZOPE
by Jerry Spicklemire 28 Apr '00

28 Apr '00

Hi Zope fans, Just to let everyone know, below is a copy of a message I sent to Phil Greenspun, about some errors in his document. Hopefully he won't get swamped with duplicates. Later, Jerry S. There are many examples of the Zope team leveraging pre-built tools, and two examples you mention to the contrary (below) are in fact erroneous. "For example, they built their own Web server (ZServer); we used AOLserver..." ZServer is Sam Rushing's "Medusa" http://www.nightmare.com/medusa/index.html "Zope built their own database management system; we used Oracle out of the box..." Zope uses Aaron Watters' "Gadfly" http://www.chordate.com/gadfly.html Also: "Compare http://www.arsdigita.com/pages/toolkit/modules.html to what you find at www.zope.org and you'll see the practical difference in terms of pre-built modules." Maybe you didn't notice: http://www.zope.org/Products Personally, I think you should include a link that points to your own assessment of PostgreSQL* ( http://photo.net/wtr/aolserver/introduction-2.html ) instead of "force feeding" Oracle, especially after espousing Open Source, and then rejecting your own advice. It would appear to be a more balanced view, even if you believe the effort outweighs the cost difference. Care and feeding of Oracle is FAR from effortless! Later, Jerry S. * "The open-source purist's only realistic choice for an RDBMS is PostgreSQL, available from www.postgresql.org. In some ways, PostgreSQL has more advanced features than any commercial RDBMS. Most important, the loosely organized unpaid developers of PostgreSQL were able to convert to an Oracle-style multi-version concurrency system (see below), leaving all the rest of the commercial competition deadlocked in the dust."

Pound sign in object id causes dtml-tree problem
by Richard Moon 28 Apr '00

28 Apr '00

I thought I'd pass this on. I have a simple dtml-tree which shows dtml-documents inside folders. I found that if I use a UK pound sign (£) in the document id then I get a problem - the document shows in the tree but I get a not-found error when trying to open it.
