New Security Rules ... are very frustrating
by Stephan Richter 07 Dec '01

07 Dec '01

Hello everyone, I have a major issue with the new security. Let's say I have class X (a nice Zopish object) and an object Y. class X: Y = Y Now, I am still able to access Y in an instance of X, like: x = X() x.Y but I am not able to access method do_z() anymore. x.Y.do_z() BTW, Y is not a nice Zope object but an instance from anywhere. And setting __allow_access_to_unprotected_subobjects__ does not help much either and it should not be the final solution anyway. Can anyone help? Regards, Stephan -- Stephan Richter CBU - Physics and Chemistry Student Web2k - Web Design/Development & Technical Project Management

Uh, this is brand clarification... Sometimes people (well, people who don't pay enough attention) don't get that company X is associated with product Y. Look what happend to Borland when they changed their name to Inprise but kept the old product names. For those folks who don't pay attention to every detail of goings on in the Zope community, or are not subscribed to lists, or are new to Zope, I imagine that a name discrepancy could be confusing... I hope you aren't saying that basic, well thought-out, marketing strategies are somehow predatory behavior? Let's not even try to compare this to "hijacking" in the style of a certain Redmond-based company.

I'm going to suggest that this is off-topic for zope-dev, as this is a list fostering cooperation among developers who do not mind sharing their 'beans' and who do not hold the delusions of conspiracy theory. If you are not willing to play by the ad-hoc cooperative social contract of this development community, please go away. This is my last post on this matter, and I suggest others follow suit. Anyway, you do know all kinds of embarrassing health problems can happen from hoarding beans, don't you?

This is what makes the free market work and I would do the same thing if I was in their shoes. However, I am not in their shoes, and therefore don't want to brand their company and don't want to add my beans to their pile of beans. Thats all I was saying.

Open Letter to zope-dev
by Andrew Kenneth Milton 07 Dec '01

07 Dec '01

Since I seem to be the cause of all hell breaking loose over here, I thought take the opportunity to respond, since I haven't really been given an opportunity to do that. Since this probably going to be my only ever posting to zope-dev, I don't feel constrained to be brief in exercising my right of reply. I'm not going to apologise for the comments I made, or the manner in which I made them. Those comments were made on a list run by me, basically for my own amusement. If I had posted either of those emails to someone else's list, I'd quite rightly deserve to be fried. I don't make money from Zope Development (I don't make money), I don't run a website, in fact, I don't actually use any of the products I have released. So it's not like I have a vested interest in Zope. My fortunes don't rest on the success or failure of Zope or any one of its components. I live in a country the size of the USA that has the approximate population of New York State. Even if I stood on a busy street corner with a loud hailer, the number of people I could actually influence would be small. This makes me one of the people in the trenches. It is the people who are in the trenches who are increasingly being disaffected by Zope Corp, it seems as if you're not subscribed to zope-dev, you have no voice, and for most people zope-dev is not an appropriate forum for them to be subscribed to. As some of you know, I was hounded off of the zope@ mailing list for suggesting that there be some other mailing list for more technical discussion. People were very upset, because, they already have a hard time getting any support. Noone from Zope Corp seems to monitor the list to help out. The zope list was manned by people like me volunteering expertise and time to help more of the little people. A lot of those people come to the irc channel, which is also rarely if ever visited by anyone from Zope Corp. Most people know that #zope is the place to go when all else fails. The major irony of this is, that most of the people seeking help on #zope are working with it, or consulting with it, and are supported by me and others for free. We are the ones that deal with the 'general zope public.' We are the defenders of the faith. The Zope Weekly News, which turned into Zope Monthly News, which now has not been updated since October is a joke. It shows Zope Corporation's attitude towards their community. It says "We don't care about our community." I'm sure that's not the feeling of the *individuals* inside Zope Corp, I'm sure it is (or I hope it is) a source of great embarassment to those individuals that work for Zope Corp. Letting your community showpiece atrophy doesn't show any great passion towards us, it certainly doesn't endear new users to Zope. New users are the only way Zope Corp is going to make more money, unless of course zope.org is just for us non-revenue generating little fish, an inconvenience associated with having Open Source software, not something that promotes and supports the non-paying community. Noone wants a standardised User Management API more than me. I *want* to have confidence that someone can replace any User Folder with XUF, and it will just work. So when I come across something that says there is a New User Management API, I get excited. I prepare to roll up my sleeves and make the necessary changes to make software I contributed to the community continue to work. I think we all know by now my opinion on what I found, the harshness of the expression of that opinion is directly related to the way that these days Zope Corp seems to be an Ivory Tower and the way they seem to treat the community at large. There are approximately 450 products released by just over 200 people on Zope.org. There are approximately 1000 'entities' subscribed to this list (more to the main list), I represent 0.1% of this community, but, am responsible (but, not soley) for 3% of the total product space available. If people want to form an opinion of me based on one email, that's your right. You don't have the right to tell me, that *I* don't have the right to say the things I'm saying. I have earned the right to make these comments, I have contributed time, effort, and code, and I put my money where my mouth is. I'm not some backseat political observer, I am in the trenches I deal with the disaffected, the confused, and the generally pissed off every day. In my efforts, I try to help to make Zope a better product. You would be hard pressed to find a more stalwart supporter of Zope than me. This doesn't mean that I have to think that everything that leaves the holy temple of Zope Corp is the panacea of web development. My opinions might be wrong, but, they're not wrong simply because something was released by Zope Corp, or written by some person you have attached some god like status to. I will continue to do my thing, but, the way Zope Corp deals with us, the little fish had better change, or there's not going to be much of a community left. Those of you who subscribe to zope-dev who think that your time is too valuable to be spent helping others, well, words fail me. -- Totally Holistic Enterprises Internet| | Andrew Milton The Internet (Aust) Pty Ltd | | ACN: 082 081 472 ABN: 83 082 081 472 | M:+61 416 022 411 | Carpe Daemon PO Box 837 Indooroopilly QLD 4068 |akm(a)theinternet.com.au|

Personally, I am of the opinion that sending a Catalog raw queries is not very useful for really powerful searching... hopefully this changes in the future, but for now... Since catalog doesn't have anything built-in that does this, other than globbing vocabularies, you have to do this within your appliction. What you want to do is hijack and rewrite user queries before sending them through a catalog query... for example: word = 'dancing' newword = re.sub('ing$', '*', word) #newword is now 'danc*' which This would work with plural words as well, as long as you have a useful set of patterns for word endings... For alternate spellings, abbreviations, and synonyms you would need to create lookup tables and indexed methods that took advantage of them for text indexes. This works only for text indexes though... In summary, use query rewrites for word endings and auto-wildcarding (the work is done at search time)... and use methods that weight and translate your text in your product code (the work is done at index time)...

RAMCacheManager and gzip
by JanStiller＠t-online.de 06 Dec '01

06 Dec '01

Hi, Is it possible to marry the RAMCacheManager and gzip? I'm just working on a little shop and - for speed's sake - do 'ram-cache' the article-listings and push all the Zope-Content through mod_gzip. With this combination, I'm getting it 3x faster in Zope and 5x faster over the wire (normally 64k). That's great so far. But I don't see any sense in zipping cached content over and over, so I tried to zip the cached data in RAMCacheManager. In my first attempt, i replaced: ZCache_get (RAMCacheManager.py): entry.access_count = entry.access_count + 1 return entry.data with: entry.access_count = entry.access_count + 1 ob.REQUEST.RESPONSE.setHeader('Content-Encoding','compress') return zlib.compress(entry.data) The results: 1. This works with Mozilla 0.96 only for very small entry.data. When I set entry.data to 'XX', it works, but any real page gets '<html><body></html></body>' as the result. 2. This doesn't seem work in IE alltogether. (with 'Content-Encoding: gzip' - zlib.compress != gzip!?) I'm willing to spend some days of work for this feature, but although I have 2 years experience in Python I'm quite new to Zope and Internet-RFCxxxx's and this is definitely a point, where I would appreciate some hints from more experienced Zope-programmers (or a product, of course -- or the statement, that this won't be possible... ;o) regards Jan Stiller P.S. sorry, if my words seems a bit confused, I'm more used to reading than writing english...
