Now that I read the manual ;-) I clearly see that is what the dtml-sqlvar prevents. Thanks! There has been a lot of buzz about sql injection lately for some reason and I just wanted to make double sure I understand the basics.

Best place for libraries
by Gabriel Genellina 21 Mar '05

21 Mar '05

Hello I'm migrating from Zope 2.6 to 2.7 with an INSTANCE_HOME. In the previous setup, we had: Zope lib python <some shared libraries> Products <standard products plus some from external sources plus some developed in-house> java <other Java packages comunicating via xml-rpc> Now we have a SOFTWARE_HOME and an INSTANCE_HOME and I'm not sure where is the best place for each directory. Our own products (which are specific for the application) surely go under INSTANCE_HOME. But CookieCrumbler, by example, as an external product, should be under Products in SOFTWARE_HOME or INSTANCE_HOME? What about some shared libraries not related explicitely to Zope (like HyperText, an OO HTML generator)? Should be on SOFTWARE_HOME\lib\python? or maybe outside the Zope dir, in lib\site-packages inside the Python install? I know there are many ways to do this, I'm looking for some "best practices" or something like that. Gabriel Genellina Softlab SRL

Create zope documentation mailing list
by KLEIN Stéphane 21 Mar '05

21 Mar '05

Hi, I think than a zope documentation mailing list can be a good thing to coordinate work on zope documentation. I would like work on it, but I don't know who maintain it, what is the road map,... If this here isn't good place to speak about this, please say it me. regards, Stéphane

image border in Zope 2.7.x
by Chris 21 Mar '05

21 Mar '05

Hi, this is a rather trivial problem: I updated a Server from 2.6.2 to 2.7.4 I noticed that all images used within link tags are shown with a border if <a href="#"><dtml-var my_image></a> is used (yes, I know: use PT ... it's not my code) unless I set a style (border-width:0). 2.6.x did not show this border. Is there a simple way to change Zope's way to render image-objects globally? I dont' want to change the dtml-code of other people's if possible. Regards Chris

Mac OS X 10.3.8 Webdav + Zope 2.7 + Powerbook Hangs
by Pavel Zaitsev 21 Mar '05

21 Mar '05

Hi, I am having issues editing files over webdav on my powerbook. Zope is mounted via webdav and I am using vim with nowritebackup configured. Since such configuration is similar to what many may use on this list I thought some of you may shed some light on what is happening. Here is steps i go through: 1. book powerbook (postgresql 8.0 starts at that time as well) 2. i login, start console, sudo su to root, do zopectl start 3. mount webdav with Ctrl-K on finder 4. Open shell, change over to /Volumes/127.0.0.1/web_space 5. edit files saving them once in a while, using vim. Now problem is sometimes I save and the console/vim/webdav mount locks down. Meaning that if I access /Volumes/127.0.0.1 from other console, it will lock up too. After little while applications related to file system(all of them?) start to lock up, like Finder, on CMD-N does not open new window, but puts a beachball cursor up. Itunes keeps playing fine until it needs to change song file. It is really really annoying I might suspect zope/webdav issuing dns lookup in some critical section that does not return, or some such thing, since lockouts last around 2-3, maybe 5 mins. Once time passes all requested actions complete, ie New window for finder opens. Curious thing, though that vim says that file has been changed since my last save and if i want to replace whatever is on webdav mount. Vim checks for change date/times, I suppose. Any insights of Mac/Zope users would be appreciated. Pavel

Accessing to ZOPE_HOME
by leticia larrosa 21 Mar '05

21 Mar '05

Hi all: How can access to the value of the "ZOPE_HOME" that Control_Panel shows in the Zope Management Interface?. My target is read in execution time a content of one external method, but my zope server can run over windows or linux, and i must refer the folder when the zope are installed, indeed when the external methods are located, for example: "/usr/lib/zope2.7/Extensions" or "C:\Program Files\Zope-2.7.4-0\Extensions" I prove with "os.getcwd()" but the value returned is for example:"/var/lib/zope2.7/instance/..."

I guess I'm doomed. ;-) I use MyISAM tables mainly because that was all that was available way back when the database was created. That was when MySQL was not concerned with and was even proud that they were not SQL compliant. Now years and 100Gig+ later nobody is brave enough to change the table types. Looks like I should at least change the table type on tables that Zope write to. > -- > Computer interfaces should never be made of meat. > > Using GMail?

running fsump.py
by Sean Hastings 20 Mar '05

20 Mar '05

I am trying to run fsdump, but am having import issues. Both my windows and linux boxes have Zope installed and running, but when I try to run fsdump.py on either machine, I get an import error: # python fsdump.py Traceback (most recent call last): File "fsdump.py", line 5, in ? from ZODB.fsdump import fsdump ImportError: No module named ZODB.fsdump and despite various attempts to set the PYTHONPATH, I have had no success getting python to find the ZODB.fsdump code. A Google search for this error is producing nothing. Any ideas?
