odd zope behavior -- variable size limits?
by Keith J. Farmer 17 Nov '01

17 Nov '01

I've got a calculation engine written in C, extending python. I've noticed that nearly every time I try to run a calculation using it, via http://www.thuban.org/astro, apache complains that it can't reach the zope host (error 502). This happens with the Get Poly function in particular, though the Get Coords function also suffers. Given time, a refresh will pull up the results. I suspect the pages are eventually cached, and it is that cache which I access. I'm trying to figure out how best to solve this dilemma. The process for Get Poly works like this, using external methods which act as stubs to the C extension: *call dataset cruncher (internal to the cruncher, get big uber dataset [~100k, more or less], perform calculations that run about 10secs or less, and then pass back roughly 20 numbers as a result) *call result verifier (repeat the above, comparing the original dataset against the results from the last step, which are a least-squares polynomial fit, and return the rms and maximum errors) .. then display the results. I notice that there's a lot of disk activity when this process starts up. I'm wondering if it's always reloading the dll file, or if apache's too impatient, or what. The platform is a Win2k Server, with roughly 200M+ free at any given moment. The database is an MSDE/SQL Server database being accessed through ODBC. ---------- Keith J.

Help! Data.fs corrupted
by zope＠meadowbase.com 17 Nov '01

17 Nov '01

Hi everyone, I'm an experienced Zope user/developer and have never seen anything like this. It appears data.fs is corrupted. Here's the message I get when attempting to start Zope (it's version 2.4.0 on solaris): ------ 2001-11-17T00:51:59 PROBLEM(100) ZODB FS FS21 warn: /local/home/a1142/zope/Zope-2.4.0/var/Data.fs time-stamp reduction at 4995254 ------ 2001-11-17T00:51:59 PROBLEM(100) ZODB FS FS21 warn: /local/home/a1142/zope/Zope-2.4.0/var/Data.fs has invalid status, , at 4995254 ------ 2001-11-17T00:51:59 PANIC(300) ZODB FS FS21 ERROR: /local/home/a1142/zope/Zope-2.4.0/var/Data.fs has invalid transaction header at 4995254 ------ 2001-11-17T00:51:59 PANIC(300) z2 Startup exception Traceback (innermost last): File /local/home/a1142/zope/Zope-2.4.0/z2.py, line 564, in ?

I use WebDAV to edit ZPT documents, but had never done so on this particular installation. I changed the start file to open a WebDAV port, and it seemed to work. I was able to browse, edit, and save ZPT's into the database via WebDAV. Meanwhile I had a browser open, operating in a Version. I was curious to see if there's anyway to work in a Version via WebDAV (meaning a Zope Version). Doesn't seem like there is. After the WebDAV save I started getting cryptic traceback/error messages in the browser. (Sorry I didn't record the messages, they were errors about type conversion. One of them was about trying to convert a longint, and another one made specific references to dates.) Those errors appeared whenever I hit the "Undo" tab on any object in the database. So I stopped Zope and this error comes up when I try to restart. Has anyone experienced this problem? How can I prevent it in the future? Is there any way to recover the data in Data.fs? Thanks! --- Francis Potter

Re: Getting SQL record names in python script?
by azbok＠yahoo.com 17 Nov '01

Thanks for all the info about getting the record names. I used the names function and it works great!! If anyone is interested, I searched for dictionaries in zope.org and found a nice link explaining the ZSQL results class. The results class is the object returned from a ZSQL method. The link is http://www.zope.org/Members/spinwing/ZSQL_Results

WebFolder Problem?
by Luis Cortes 17 Nov '01

17 Nov '01

Hi there, I am running webdav on my linux system. I was wondering if anyone has a problem with the "ghost" folder that shows up IN your folder with the same name AS your folder. I.E. 1. Suppose I create a folder at the root called test 2.then if I set a webfolder to test, www.mycom.com/test 3.I not only see the contents of test, but also a "ghost" folder called "test" Is this a bug ? Is there a fix ? Am I just doing something wrong ? Thanks ahead of time for any help, Regards, Luis.

okay, getting somewhere
by Jacob Singh 17 Nov '01

So I created the phrases table by simply running the SQL Method that contains its code. The problem seems to lie in the action of the form that initiates tables, I think in general there is something wrong because if I try to use the program, SQL is not executed, at least I think so, because nothing happens and I receive no errors. I want to know where this file : manage_initTables is. I'm sure this is something obvious, but I'm new to Zope and still haven't really wrapped my head around the file indexing system. Later, J
