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?

apache rewrite blues.
by Wombie Tomek 20 Mar '05

20 Mar '05

i have an apache rewrite that looks like this: RewriteEngine On # RewriteRule ^/(.*) http://127.0.0.1:8085/VirtualHostBase/http/www.thoracicavity.com:80/wombie/… [L,P] RewriteRule ^(.*)$ http://www.thoracicavity.com:8085/VirtualHostBase/http/www.thoracicavity.co… [P,L] the former one didn't work any better than the one i'm currenly using. for whatever reason any sort of querystring i try to pass fails, and zope gives me a server request failure. Searches, Zphotos, anything using a querystring is broken... but everything else is perfect. What is wrong with my rewrite? my complete virtual host setup looks like this... and there is nothing unusual in my error log and my access log just looks just fine like the queries got passed ok. 68.93.160.73 - - [19/Mar/2005:17:58:21 +0100] "GET /search?SearchableText=adfasdfasd HTTP/1.1" 404 3392 "http://www.thoracicavity.com/" "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.6) Gecko/20050225 Firefox/1.0.1" etc.... <VirtualHost 62.23.25.244> DocumentRoot /Data/sites/www.thoracicavity.com/web/ ServerName www.thoracicavity.com ErrorDocument 404 http://www.thoracicavity.com/404error.php CustomLog /Data/sites/www.thoracicavity.com/log/access.www.thoracicavity.com.log combined Alias /webalizer /Data/sites/www.thoracicavity.com/webalizer RewriteEngine On # RewriteRule ^/(.*) http://127.0.0.1:8085/VirtualHostBase/http/www.thoracicavity.com:80/wombie/… [L,P] RewriteRule ^(.*)$ http://www.thoracicavity.com:8085/VirtualHostBase/http/www.thoracicavity.co… [P,L] </VirtualHost> holden thomas

fsdump.py output
by Sean Hastings 20 Mar '05

20 Mar '05

I am running fsdump.py to see what is in my Data.fs file, because it seems to be growing a lot faster than it used to. The beginning of the file is a large number of object listings as expected. However, about half way through I start to see a lot of transaction information. These transactions are still in the file even though I have consistently packed the ZODB once a day. The dates on these transactions start a few moths ago, and relate to various functions in a product I have been working on. Is there something that I could have added to the code at that time (perhaps committing parts of transactions to avoid conflicts) that could be causing this transaction information to be left in the Data.fs file even after packing it?

They're clearly bugfixes to me; that shouldn't be a hangup here. What's missing is a Zope committer who runs on Windows volunteering time to commit the patches in 2.7-land, and to port them to 2.8- and 3.0-land (those require more than just mechanical merge, because things like moving to Python's standard logging module require rewriting code). Alas, Zope in Windowsland attracts about as much volunteer work apart from Mark Hammond as, say, Python 1.5.2 in Windowsland did. Mark understands what that means. Everyone else can read it as "except for building the installer, hard to distinguish from none" <0.7 wink>.

dtml-tree: Passing parameters to branches-method
by Ulla Theiss 19 Mar '05

19 Mar '05

Hallo list, how can I pass a parameter (namely the REQUEST-Object) to the branches-method of dtml-tree? I tried the following: <dtml-tree branches="getBranches(REQUEST)"> branch: id: <dtml-var id> <dtml-var title_or_id> </dtml-tree> But it seems, the method "getBranches" isn't called at all. No tree is built up, but there isnt an error-message, too. Many thanks in advance, Ulla.

Change properties -> auto-update
by Gre7g Luterman 19 Mar '05

19 Mar '05

I've created a product with a zClass that has a couple of property sheets. Users can place this product in their web hierarchy and edit properties with the Properties tab. This all works just fine. The problem is that modifying one of the properties needs to have a side effect. I would like to update a database if this property is changed. Is there an easy way to hook into this process so I can set up a side-effect script? The default propertysheets/Basic/manage page posts the results to propertysheet/Basic, but I'm fuzzy on how (or if) you can change the processing of this script. I suppose I could replace the page that displays the properties and have it submit the changes to a custom script, but I'm not exactly crazy about that idea. The downside of that route is that hardcoding the template page with one of my own will lose me the flexibility I have now. If I add a new property, I'll have to remember to add it to the template. Or does anyone know where I can find the current template that dynamically shows the property form, so I can make a modified version for this product? Gre7g

Zope on Windows - REQUEST for volunteers
by Andreas Jung 19 Mar '05

19 Mar '05

Hi, there are several open issues in the Zope collector with Zope running on Windows. I can't see anyone worrying about the Windows platform (I also don't care about Windows as UN*X guy). So if you are interested in running Zope on Windows in a reasonable way than *you* should help to fix the outstanding bugs. I heard some remarks (behind my back) that Zope is not a stable solution on Windows...possibly.....but since Zope is a community-driven project people doing such remarks should either shut up or help to improve the situation by volunteering (which is also true for other parts of the Zope development). So if you want to improve running Zope on Windows: go the Zope collector, search for Windows related problems, find a solution, submit a patch and don't expect that everything can be handled by the handful of active Zope 2 core developers...means it's also up to *YOU*. Andreas
