Corrupt Data.fs: Is there a way of fixing transaction ids?
by Joachim Werner 05 Aug '02

05 Aug '02

Hi! I have a really large Data.fs file (1.3 GB) that has a number of errors. When I run the fstest.py script, I get this: Problem: 109963117 object serialno 0x034573c4b6a2cb6e does not match transaction id 0x034573c55c8c0dbb How can I fix the Data.fs file? It should be possible to scan the Data.fs and create correct serialnos or transaction ids for the broken entries. But how exactly would I do that? I'd also like to identify the corrupt entries (i.e. find out the Zope object they belong to) to be able to eliminate them. My ultimate question is how these corrupt entries can exist at all. The Data.fs hit the 2 GB border once. So that could be a reason. But even then it would be really nice for the ZODB to not write corrupt entries ... Any help is appreciated ... Thanks Joachim

calling zsql-methods with variable queries
by Arthur Tomas 05 Aug '02

Hi, can anybody tell me any possibility for calling ZSQL-Methods (MySQL) with variable queries ... something like: in python: query = "select * from myTable where myColumn=42" return context.sqlMyQuery(query) in zsql method: <dtml-var query> and so on... but it does not seem to be the right way...

RE: [Zope-dev] Yeat another ZMI improvement idea...

Thanks for the suggestion. I'll look into PatchKit, and if this works out, I'll try work in this type of improvement. Does patchkit set a cookie with a complete list of hidden products, or does it do any part of the preference storage server-side? A thought occurred to me, though, as a solution for tracking usage of add forms (problem #2): create a redirect page that logs usage in between the OM manage_main and the manage_addProduct/* that are called (at this point) directly from manage_main...

Have you looked at PatchKit? It contains a patch that allows you to "hide" products you don't use.

This looks a lot like an idea that would lend itself to PatchKit - And you could let it do a lot of the work of actually patching for you.

Yeat another ZMI improvement idea...
by sean.upton＠uniontrib.com 04 Aug '02

After playing around with Evan's ZMIBookmarks (which I like), I got to thinking about persisting (or semi-persisting) other user preferences for ZMI shortcuts. In some word processors, the font drop-down remembers the last few choices of fonts you selected and puts them at the top of the drop-down list. This is really nice if you have a bunch of fonts installed on your system. I think the same concept could apply to adding Zope products in the ZMI, provided you have a fairly decent number of products installed in Zope, you have to scroll every time you want to add something that doesn't begin with the letter A. So, I'm thinking shortcuts at the top of the contents in the drop-down for adding an object to a container. It would be nice if there was a way to put the 3-5 most recently used products at the top of the list on a user-by-user basis, and persist those user preferences somehow (this really is a good thing, since, for example, DBAs might only need to add ZSQL Methods, Python Scripts, and DA objects). I would be interested in creating something like this, but I'm interested in getting list feedback on: 1 - the best way to persist the user preferences, and 2 - How one would go about tracking what items were selected, since each product maintains its own add forms, and can't be relied upon to update a registry of said user preference... 3 - the best way to approach the UI (I assume a monkey patch to the DTML for OFS.Folder's manage_main and a simple registry of preferences that can be used to populate the top of the list based upon the user's login) Any input is appreciated.

Hi, I'm searching a way to execute a ZODB untrusted python script with parameters and appropriate bindings (context, container...) from a file system Zope product. Where can I find some examples ? Thanks in advance. --Gilles

Refer to zope attribute or object in source
by kent sin 01 Aug '02

01 Aug '02

In PropertySheets.py of zope/lib/python/OFS def xml_escape(v): ..... return unicode(v, "latin-1").encode("utf-8") Are there anyway to substitute the "latin-1" with an attribute of the zope site's attribute say: "zope-charset" which a site maintainer can modify through the web? I raise this question because the current-cvs version of zope is turned into unicode, but all the source everywhere is assumed that the data input is "latin-1" but I am very sure that it will not always the case. Some sites simply don't work in that assumption, turning many sites using zope stop upgrade or stop using zope. This will seriously hurt the zope community. The initial act to make zope understand unicode is to help zope internationalize, but the actual effect was not. I urge the zope developer, the zope coporation as well as product developers (some products like ieDocument and worldPilot have "8859-1" specified in their source) alert on this issue, and take action before it is too late. The best solution I could come up with is to allow individual site manager to choose its default charset and allow other site-branch manager to overwrite it with acquisition, thus the attribute zope-charset will be used to determine both the "Content-type: text/plain; charset="<dtml-var zope-charset>" and the code convertion of Zope like PropertySheets.py __________________________________________________ Do You Yahoo!?

Zope hangs, with processes being idle ... (rather urgent problem)
by Joachim Werner 01 Aug '02

01 Aug '02

Hi! I have a Zope 2.5.1 using ZEO on Linux, with Apache as proxy server. The two ZEO clients run fine for a couple of hours, and then suddenly one of them stops responding. It's the type of Zope hangs when all processes are fine, but ZServer just doesn't respond (load is very low, with the CPU 90% idle, so it is not a performance issue or recursion problem). There is no error before this situation happens. The processes just don't respond any more. The second ZEO keeps running, but that machine also hangs from time to time, so I guess ZEO is not the problem, and the hardware or any Linux-specific problems aren't either. When the ZServer hangs, I can not access it directly, so it is no problem with the Apache. You see, I don't have any clue on what is happening here. The servers worked fine for months, and I don't know what specific change could have caused the problem. How can such a situation be debugged? Cheers Joachim
