There are people who code Perl, Python and Zope every day and don't know, care about, read or post to comp.lang.anything. Bajillions of them in fact - a healthy majority. The decision whether to add a language should NOT be made on the basis of what a few Usenet addicts think. It should be made on the basis (among others) of whether it adds desirable functionality and "marketability" (for profit or otherwise) without fatally complicating the product. I think Perl methods will be very popular and not particularly difficult to maintain as a Zope feature, although I do anticipate some complications down the road as new Zope, Python and Perl releases see the light of day and have to co-exist on various platforms. > I can pretty much gaurantee that oce we start getting perl people on the > list, doing stuff in perl, the following scenario will occur repeatedly: > > "I want to do this, how do I do it?" > "like this...<python code>" > "I don;t want to use python, I want to use the all cool lnaguage of > perl" > "Sorry, can't help you" ... Actually what will probably happen is that someone will ask "I want to do this, how do I do it" and one or more Python enthusiasts will say "like this... <python code>" and one or more Perl enthusiasts will SIMULTANEOUSLY say "like this... <perl code>" and the user will pick what suits them, and get back to work. Only the professional arguers will have the time to fight over this stuff.

RE: problems with NTUserFolder.

I see how it works now. I installed jcNTUSerFolder but couldn't get it to work. I thought it did the challenge response stuff for me. I didn't realize it had to go behind IIS. I'll give it a try. > -----Original Message----- > From: Jephte CLAIN [mailto:minf7@educ.univ-reunion.fr] > Sent: Thursday, May 25, 2000 8:14 PM > To: Jay, Dylan > Cc: 'zope(a)zope.org' > Subject: Re: problems with NTUserFolder. > > > "Jay, Dylan" a écrit : > > > > I can't seem to get your product to work the way I want. > I'll tell you what > > I'm after and perhaps you can tell me where I'm going wrong > or if indeed > > your product can do it at all. > > > > I have a group of users who are all part of the same domain > as I am on.

When you install Zope as as pcgi process to get through IIS, it is the *only* way to be authenticated and get, for example, to the management screens. When you install jcNTUserFolder as the root user folder, you have to choose the NT user that will be mapped to the super user. The first time, you have to log with that user. Note that this 'super user' needn't be a privileged one under NT. regards, jephte clain minf7(a)educ.univ-reunion.fr

I even sent Shane an immature snapshot, but had to reimplement the product because of nesting ZClasses (sigh). Moreover, I was changing jobs as well, which did not exactly help in getting things from the ground. So - yes I'm still interested Shane. Rik

Hi. I have lost the patch for Roxen 1.3 to work properly when you enable RXML-parsing for CGI, i.e. Zope. Who has it? /Magnus Heino

SQLSession and Memory leak
by Hung Jung Lu 26 May '00

26 May '00

Hi, This is just for people's information on my own experience in Zope memory leak. It may not reflect your personal case. But if it does, please post a note to the mailing list. When there is a problem, people have to face it. I really dislike the attitude of people who just shrug their shoulders. I have seen this all too many times. Everytime I go through a problem and posted in to the mailing list, there are always people that try to say nonsense and refuse to accept that there is a problem. Guess what? Weeks later more and more people suffer similar problems. By now I am very sure that a huge memory leak is coming from SQLSession. Remember about one or two months ago I mentioned about memory leak in Zope? There were so many die-hard Zope mongers that the very first thing they feel is their pride being hurt, and instead of looking at possible sources of the problem, their attitude was: it can't be, you must be doing something wrong, Zope has no memory leak. Now, does that attitude help to find the source of the problem???! Perl mongers are bad enough, and now we have Zope mongers. The thing is, no one would complain about memory leak if there is no performance impact. When someone complains about memory leak, it's because the performance is getting to be unbearable. After using SQLSession with two different databases (Gadfly and Sybase), and after the problem persisted, and after using manage_debug in Control Panel, I have decided that enough is enough. I implemented my own RAM-based Session Management. And it's been about a month now. No more memory leak. Zope memory usage stayed nice and low. Performance improved substantially to the amazement of everyone. No more need to re-start Zope to bring the memory down. There are hundreds of people out there using SQLSession. I know for fact that someone using SQLSession has actually written a Unix cron job to restart Zope every night in order to keep the memory usage down. (Of course, the person does not know the memory leak is coming from SQLSession.) >From the manage_debug screen, it seems that the leak has something to do with the SQLSession inheriting from Implicit class. I don't remember much anymore (since I got rid of SQLSession already a while ago.) I just remember the keyword "Implicit" showing up in the objects in the manage_debug screen. All I know is that after I stop using SQLSession (mainly with Gadfly, which was a temporary solution anyway), my problems stopped. regards, Hung Jung ________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com

My boss isn't going to suddenly tell me that I'm now either a perl developer or unemployed, because he hired me for my judgement & decision skills as well as my keyboard pounding skills. If your boss didn't hire you for that reason - well, its an excellent time to be a skilled IT worker looking for a job. & if your boss doesn't value your intelligence and also wants you to suddenly hack perl, then your boss didn't read your resume. & to reinforce what Ken says: > For all of you that love Python, and testify to either leaving perl > with great relief or not being willing to learn it in the first place > - why don't you trust your judgement? It's also an even more excellent time to be a sklled Zopista looking for a job. Find a good place looking to start a Zope project, build them a site, & you'll be deciding whether to use Perl products or not. I can understand the fear of dilluting a good clean python/C environment with evil dirty perl, but if I didn't think that a Zope environment will continue to be a good place to be, I'd already have a different email address. -- Karl Anderson karl(a)digicool.com

Hi, I see Amos has a tutorial. Could this be added by default to each member's Zope area on Zope.org? Might me useful almost as a small 'demo' of Zope's features.
