I have made a set of scripts for win32 that build Zope from the source distribution just like the provided scripts do on Unix systems. I just used them today on two different NT systems to build Zope 1.10.2. Go to http://starship.python.net/crew/robind/#zope to get the zip file and follow the instructions on the page. Since these scripts create makefiles and use nmake, the only requirement is having the MS VC++ 5.0 or 6.0 command-line tools installed and properly configured (with environment variables and such, use the vcvars32.bat or whatever that the VC++ install creates.) -- Robin Dunn robin(a)AllDunn.com http://AllDunn.com/robin/ http://AllDunn.com/wxPython/ Check it out!

Too cool - it looks like amos will have a Zope article in WebReview, thanks to timely mention of Zope by kevin dangoor to the editors. It's amazing how a few words at the right time can make a difference in *spreading* the word! Please, everyone keep your eyes open for such opportunities - this is clearly as situation where the more is the merrier. Thanks kevin - well done! ken klm(a)digicool.com

Possible Bug Report: Corrected Broken Products do not appear righ t any more t any more
by Stefan Franke 26 Feb '99

26 Feb '99

It seems a broken product that is corrected still is shown as broken in the products folder on next restart along with the old traceback. This appeares first to me first with 10.2.1 on Win NT4. If someone could pls confirm this I'll add it to the bug tracking list - just add a typo somewhere in ExternalMethod.py, start Zope, remove it, and start over. Stefan

DISCUSS: Import from the web
by Paul Everitt 26 Feb '99

26 Feb '99

I need you folks to help us figure out how to add a sweet little feature: import from the web. Scenario: you work from home on a bunch of information in a Zope folder, like documents, images, Z Tables, etc. You get into work and want to blast it onto your remote Zope-based website. With Zope 1.10.2, you now have an interface to do this: you first export your folder on your laptop, move the export file to the filesystem of your webserver, and import the folder on the webserver. There are certainly some scripting things you could do in Python to make this a bit more seamless. But wouldn't it be nice if you could tell the two Zopes to swap information directly? To date we haven't done this for security reasons. Since export files are series of records containing pickles, the unpickler could be tricked into doing something unpleasant. While this could still happen under the current scheme, at least you know the person was trusted enough to log into the OS and be allowed to write to the directory. Thus, the current import/export scheme isn't about preventing damage, it (like External Methods) is about proving someone is trustworthy. Let's say we leave off the table right now consideration of making the import more immune to hijinx. Let's also leave off the table related issues (like synchronization or replication conflicts). Let's just ask the question: "Can we make import-from-the-network have as acceptible a level of trust as the filesystem?" Here are some brainstorm ideas: 1) Make the import a pull rather than a push. Instead of pushing the data from your computer into a remote Zope, you go to the remote Zope and put in the URL to your local Zope. 2) Turn import from the web off by default but have a knob to turn it on. 3) Reading directly from a Zope as it outputs an export means you're less likely to get a hacked pickle. 4) Have a shared key system, then rotor the export file (this is what we do on the unreleased Zope Network Client software). That is, wrap the data in an envelope. Of course there is still the ultimate question: is this a compelling feature? --Paul Paul Everitt Digital Creations paul(a)digicool.com 540.371.6909

Gratuitous password reminders a few days ago...
by Ken Manheimer 26 Feb '99

26 Feb '99

As many of you must have noticed, a few days ago a batch of password reminders were sent out by www.zope.org to you all. This batch was not the regularly scheduled one - in fact, it was spectacularly off-schedule - a few of you may have noticed that the reminders were dated Feb 6, 2036. The www.zope.org machine has been having some clock drift problems. We set up a frequent rdate synchronization with one of the NIST standard clocks to correct for it until we could concentrate on getting the clock problem repaired (we have enough fires besides), but either the clock drifted suddenly enough, or the rdate/standard clock sustained some terrible fluke, that a bad time slipped by. In any case, in its addled state the machine apparently decided it's time to send out the notices. The regular time for sending the notices is the first hour of the first day of the month. I will disable that for this upcoming month, and not trust it to a automatically scheduled routine until we track down this problem. Anyway, sorry about the gratuituous messages...

Summary of my Problems / Solutions upgrading from 1.9 to 2.0
by solberg＠platinum.com 26 Feb '99

26 Feb '99

Hello, I thought that a summary might help others that might be running into the same problem. The task: Upgrade my 1.9 test Zope to 1.10 and move it to Apache. The Problems: 1) I had Apache 1.2.6 and didn't want to lock down the zope.cgi program for all users. --- Solved this by upgrading to 1.3.3. Briefly hit a problem due to not having the ExecCGI option on the script directory. Applied the rewrite rule without much difficulty. (Hint: Don't get the binary version of apache. We needed the source to do the mod_rewrite adjustment.) 2) After having Zope running with the default database, and attempting to migrate my 1.9 database (I'll discuss this one later), we went home for the night and came back the next morning. At this point Zope wouldn't come up anymore. We could tell that the machine had been restarted. --- This one sent us on a wild goose chase. We tried the suggestions from Jeff Bauer and setup some pcgi tests. Unfortunately, all of those tests seem to refer to cgi_module_publisher or something like that. The tests all showed that this module was not found. Apparently, these tests are all out of date. The simple solution was to delete the pcgi.* files from the var directory. This allowed Zope to come back up. We decided to create a system startup script that removes these files and also loads a web page using lynx -dump. This allows us to get the pcgi process started and to test that everything is working. I volunteered to have my pager paged when the tests fail. : ( 3) We couldn't get the 1.9 database to work when we tried it in 1.10. We followed the instructions on shutting the processes down and copying the Data.bbb file. We always got a system error message. --- Within the source of the message was a traceback to the cPickle program and something about "G". Jim Fulton responded to my plea in the mailing list informing me that I needed to get cPickle enabled for binary floats. To do this, we went to the Python Modules directory and edited Setup. (By the way, we had just installed 1.5.1 of Python from Python.org.) In Setup, near the bottom, there is a line for cPickle. We added the -DFORMAT_1_3 to this line and rebuilt Python (make clean, make, make install, make test). After this our 1.9 database worked with our new 1.10 install. Thanks a bunch to Jim. I hope this helps out. Good Luck and thanks for all the great support, John Solberg

Two hours I scheduled a chat with Ken to talk about restructuring the package information on zope.org. Good timing!

Funny thing is that I don't think you can actuall find Confera on the site right now if you don't know the URL. But you're right, everything should have a Summary. Ahh, but then we slip instantly into a metadata discussion: "Is it Summary or Description? We ought to use a standard set of metadata, like [RPM, IAFA, Trove, Dublin Core, ...]" For once I'd like an answer without ten questions attached :^) > Maybe there could be a second link to a document explaining what the > component does.

I think I might understand your reasoning, but it is reasonable enough for someone to post a message to the zope@ list to find out if their problem is their fault or a bug, and then to report it to the Collector. -Michel (Keep the sugestions coming) > Michael Bernstein. > > _______________________________________________ > Zope maillist - Zope(a)zope.org > http://www.zope.org/mailman/listinfo/zope >

Also, > threads are off by default (with ZopeHTTPserver). Yes, it's all pretty confusing. We have quite a few pokers in the fire right now. The thread support only allows the I/O to be concurrent. Execution inside your app will still be nonconcurrent until Zope2. > Should I be using Zserver or is it still beta? What is/will > be better about it? Beta, we should be so lucky! :^) As Chris mentioned it's alpha, for the reasons he stated. > Should I turn on threads with ZopeHTTPserver? I did, and it > seems to work > (Redhat Linux 5.2). Is that to allow multiple simultaneous requests? As explained above, no, just to read input from the browser and send output back to it. Zope2 is the push for concurrency. This involves two main areas: a concurrent publisher and a concurrent transaction system. The first area is ZServer, which as you can see is coming along nicely. The second area is the "BoboPOS3" effort to make the database and the transaction manager able to have multiple simultaneous requests. We expected to get the database work caught up with ZServer this month, but a customer project pushed Zope Classes up the priority scale. If a customer gig comes along the requires concurrency it will certainl displace other things at the top of the list. BTW, prepare to be dazzled by Zope Classes. When combined with Zope Property Sheets, it's going to radically change the way folks think about data on the web. > I also killed my apache and switch ZopeHTTPserver to port 80 so that I > could see it from home through a firewall that I can't open > port 9673 on. > Now I can work nights and weekends, too! :) I can't see any > reason to keep > apache.
