I need to set the MIME Type of a DTML Method to "application/x-java- jnlp-file" but it doesn't work. According to www.zope.org/Members/anser/howto_dtml_mimetype I set the MIME Type in my DTML method (SimpleExample.jnlp) as follows: Content-type: application/x-java-jnlp-file , but the return of the server is: wrong mime type: text/html As anybody an idea? Thanks for any help!! Chris

Problems to login in

Hi everybody, I am a newbie to Zope, but I have found this is the rigth tool to fully automatize my web site. Obviously I need many users to log in (both managers and owners), but after I create a user within a Folder that it is not the Root Folder (hoping that the the scope of that user will be only what it is inside that Folder) I can not login with the new user's login and password. This is the error message: Site Error An error was encountered while publishing this resource. Unauthorized You are not authorized to access this resource. Username and password are not correct.

exUserFolder, ZODB & MySQL
by Jorge O. Martinez 04 Jun '02

04 Jun '02

Hi: I need some very basic authentication (to enable users to post to a ZUBB for example), and I want to use XUF + ZODB as it is the simplest setup. However, reading the docs, they seem to suggest that using XUF + ZODB is not a good idea. I wonder why, is it not secure, fast, or stable enough? The authors seem to stress that using the XUF + ZODB is recommended for testing only. I do not intend to save much users info, just the basics: name, email, etc. Less than 10 properties altogher. Nor do I expect to have 100,000+ users ;-). Perhaps < 10,000. Has any zopista outthere successfully used XUF+ZODB for authentication in a production enviroment? On a similar issue, has anybody used XUF + Mysql? There's a pgSQL schema, but for some reason there's not Mysql, anybody knows why? I don't have pgSQL available, only Mysql (3.23.38), and would rather use it if there's no issues with that. Thanks, Jorge M. -- Jorge O.

ZPatterns on OS X

Has anyone managed to build ZPatterns under OS X 10.1.4? I'm coming from a Debian Linux background so apt-get has spoiled me and I can't figure out how to get the makefile working properly. Vic

RE: [Zope] system requirements
by sean.upton＠uniontrib.com 04 Jun '02

I'm deploying a new (eventually to be very-heavily loaded) ZEO storage server on a DP Xeon/Prestonia box (running Linux 2.4.18 compiled from source from a RedHat Errata kernel source RPM with low latency scheduling enabled); the box has hardware-multi-threading capabilities; ZEO will be serving what I anticipate will be a FileStorage storage of several gigabytes sitting on a 8-spindle RAID 10. All ZEO traffic will be coming from networked ZEO clients on a Copper-GB network. One of the thoughts that I had was that it seemed at least theoretically possible that if the box is very loaded, that the HMT would help in terms of using spare CPU cycles in handling interrupts from the GB NIC and RAID Controller, but I worry that enabling HMT will compromise Python performance. Any thoughts on whether HMT/HyperThreading will help or hinder ZEO performance given Python's GIL? Could I get an accurate picture of any degradation by simply running pystone tests with HyperThreading disabled and enabled? In comparing kernel source, it looks that, unlike the stock kernel, RedHat's 2.4.18-4 kernel source has a reworked kernel/sched.c that has set_cpus_allowed() call, which should, in theory, prevent migration of a task from a CPU. Has anyone tried this with Python? Sean -----Original Message----- From: Matthew T.

Kromer wrote: > > I do *not* recommend running Zope on multiprocessor machines without an ability to restrict Zope to execution on a single CPU. The reason for this is that the Python Global Interpreter Lock is shared inside a Zope process. However, threads in Python are backed by underlying OS threads. Thus, Zope will create multiple threads, and each thread is likely to be assigned to a different CPU by the OS scheduler. However, all CPUs but one which are dispatching any given Zope process will have to then wait and attempt to acquire the GIL; this process introduces significant latency into Python and thus into Zope. Linux has no native mechanism for processor binding. In fact, there is a CPU dispatch mask for processes, but there is no facility to set the mask that I know of. Solaris can use a system command like 'pbind' to bind a process to a particular CPU. If you *do* go with a multiprocessor, be sure and tune the os.setcheckinterval() call made by z2.py. I think it should be roughly your pystone number divided by 50. This will set the coarse scheduler granularity of Python so that it doesn't attempt to move the lock as often. This will allow Zope to do as much work as it can without injecting latencies shuffling the GIL off between threads on other CPUs. In fact, setting os.setcheckinterval() to pystones/50 is probably a good idea regardless of what platform you are on. The current default is 120, which is better than the Python default of 10 -- but still means there is a lot of unnecessary lock shuffling on fast CPUs (the number 120 was reasonable 2 years ago, but isn't now -- an Athlon XP 2000+ should probably have a number of about 500). The basic idea is to allow some particular time quanta to expire before moving the lock -- but the counter is expressed in python bytecode ops. As CPUs get faster, the quanta is shrinking, rather than remaining constant -- or in other words, overhead is growing linearly with CPU speed improvements unless you make this tuning change. -- Matt Kromer Zope Corporation http://www.zope.com/ _______________________________________________ Zope maillist - Zope(a)zope.org http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )

I couldn't find any mention in the Zope 2.6 plan of support for Python 2.2. In what version of Zope might we expect to see that? Hamish Lawson
