DCOracle Large Objects
by Oleg Broytmann 19 Jan '00

19 Jan '00

Hello! Anyone can help with Oracle LOBs and stored procs? I want to create a LOB in a database. DB programmer created a stored procedure for me, but when I call it, passing data as Python string (1028 is some ID): cursor.callproc("add_image", [1028, "This is the body of my Large Object"]) I got an error. How do I pass the body of LOB to stored proc? Oleg. ---- Oleg Broytmann Foundation for Effective Policies phd(a)phd.russ.ru Programmers don't die, they just GOSUB without RETURN.

ZCatalog Find Items broken in ZOPE 2.1? (was Very important for CatalogWare zopists)
by Markus Strickler 19 Jan '00

19 Jan '00

Hi! I investigated some more on the find problem and think that the Find Items option in ZCatalog is broken. Here is what I did: - Installed ZOPE 2.1.2 Win32 Release. - Created a ZCatalog as /Catalog - Created a DTML Document as /test - Selected DTML Document in the Find Items - ZOPE finds the test Document but displays its path as /test (the link leads to http://test) *Ouch* Markus -----Ursprungliche Nachricht----- Von: Jason Spisak [mailto:jason@mtear.com] Gesendet: Freitag, 14.

Now I know I'm not going crazy. :) I don't see any way right now that could cause just a "/" to be inserted using the ZClass generated code.

How can I persist some simple data?
by Kevin Smith 19 Jan '00

19 Jan '00

I am trying to create a product that will grab all of the weather information from a weather site and return it to the document so I can render it with a DTML method. I have an extension method that is invoked with <dtml-var "download_weather(this())">. The definition of download_weather (slightly stripped down) is as follows: def download_weather(loc): city = capitalize(lower(loc.city)) state = upper(loc.state) # Download HTML and strip excessive formatting. data = urllib.urlopen(url).read() # Grab the current conditions. loc.current = get_current_conditions(data) # Grab the extended forecast. loc.forecast = get_extended_forecast(data) The weather object "loc" has a city and state property which is used to create the proper URL. get_current_conditions and get_extended_forecast both return simple classes similar to the following: class Current: def __init__(self,temperature,image,conditions): self.temperature = temperature self.image = image self.conditions = conditions The problem comes when setting the loc.current and loc.forecast attributes. They seem to do what they are supposed to when viewing the output in the management screens, but as soon as I view the output outside of the management screen I get the following error: Error Type: SystemError Error Value: Failed to import class Current from module __main__ In addition to that, the weather object turns into a Folder object which can't be modified or deleted. I still haven't figured out how to get rid of it. What am I doing wrong? -- Kevin Smith anathema(a)iname.com carpe noctum

Hey all, Our site is experiencing a peculiar side effect. As a person navigates the site, the URL in their location box keeps growing, it contains a "history" of where they have been. Any ideas on how to fix this? DR

Zope actively being cracked?
by Matthew Marlowe 19 Jan '00

19 Jan '00

Hello, www.deploylinux.net, which uses zope as its backend, was hacked on 3:30pm Tuesday afternoon. We know this because two new users were created in the /etc/shadow file and the following email was sent: From: root <root> Message-Id: <200001182346.PAA16613(a)yoda.colo.jalan.com> To: dz(a)noxiin.com Subject: yoda.colo.jalan.com * shadow detected, no login backdoor * in.rshd (atif) installed! * bLACK pANTHER kit installed @ yoda.colo.jalan.com / 216.33.174.217 The server runs only Zope 2.1, a recent version of sendmail, ftp, and an amanda client over SSH. Everything else was disabled. While identifying the source of the breakin, we noticed that a new file had been created in one of the zope directories, and that the root history logs showed that this file had been executed. Therefore, we are trying to find out if this is an active zope exploit. The server was protected by a firewall on lower level ports other than SMTP, ftp, and http. We've removed the new users and are in the process of resecuring the box. We are interested if anyone else has seen similiar events? Hopefully this info will be beneficial to others in the community.

ZServer and VirtualHost
by Cesar A. K. Grossmann 19 Jan '00

19 Jan '00

Hi! Are there a way to serve severeal domains with the same ZServer? I need to have www.domainA.com.br, and www.domainB.com.br, both residing in the same ZServer. The usual, http://zopeserver.mydomain.com.br:8080/DomainA and http://zopeserver.mydomain.com.br:8080/DomainB works, but doesn't satisfy. I'm not using PCGI (I'm with troubles making the PCGI works, something about permissions - I don't wanna address it now). I'm using Zope 2.1.2 in a Conectiva Linux (http://www.conectiva.com.br/, a Red Hat derived brazilian Linux distribution). TIA, and sorry the bad english... -- Cesar A. K.

BIG things at DC
by Rob Page 19 Jan '00

19 Jan '00

Hello everybody! First, thanks again to the Zope community which continues to grow and thrive. We're REALLY looking forward to the Zope track at the upcoming Python conference!! As always, lots of BIG things are underway at Digital Creations. I am thrilled to announce that we're opening a Digital Creations office in downtown Portland, OR. This office will serve at least two purposes: it lets us tap into an awesome talent pool in the Pacific Northwest AND it lets us more easily and affordably provide direct service to our growing ranks of Silicon Valley/southern Cailfornia customers! Naturally, our colleague Amos will be there! In addition, please join me in welcoming Karl Anderson to the Digital Creations team. Karl will also be working out of the Portland office. Karl's doc string: """ I live in Portland, Oregon, and one of the reasons that I like it here is that I'm a bad cook, and my housemates mostly take care of that while I mostly take care of the house LAN. I'm obsessed with bicycles, partly because I think they're an elegant interface between human and machine, but for some reason I'm into making crazed and dangerous cycles with my friends and destroying them on each other. I like to brag (while I can) about being the most popular Karl Anderson on the web, according to Google. """ Karl can be reached at karl(a)digicool.com Welcome Karl! --Rob -- Rob Page V: 540.371.6909 Digital Creations, Inc. F: 703.995.0412 -- ... The Leader in Open Source Web Development ... ...
