Re: [Zope] Zope 2.9.3/2.9.1 On Suse 10.1 box version
by Jeremy Smith 06 Sep '06

Howdy-- I just ran into this same problem. After much poking around, it turned out that the source of the problem was that the zlib module for Python had not been compiled because I didn't have the zlib development stuff (in zlib-devel on RH and similar, not sure about Suse) installed. Installing zlib-devel, then recompiling Python from source solved the problem.

Parameter generating an exception?
by Tit-Liviu Leontin 01 Sep '06

01 Sep '06

Hi everyone, I'm using Zope with OpenFlow for a workflow. The problem I'm encountering now seems to be entirely related to Zope; actually, a particular value for a parameter generates the error, so I'm guessing there's something wrong with the data, not the script. There's a "browse" file defined in the workflow, with the following first lines: <html><body> <html> <body tal:define="results here/Catalog; qq request/QUERY_STRING; qs python:container.stripStart(qq); start request/start|python:0; batch python:modules['ZTUtils'].Batch(results, size=20, start=start); previous python:batch.previous; next python:batch.next"> Now, if I call this script with no parameters in the URL, it shows all documents. If I append a ?issuer=john.d parameter to the URL, only documents issued by john.d will be displayed. This works even for fictive names, displaying a blank table as a result. However, for a particular user (and only that one), I'm getting this error: Error Type: TALESError Error Value: exceptions.KeyError on -1882874846 in "<PythonExpr modules['ZTUtils'].Batch(results, size=20, start=start)>", at line 3, column 3 In the page source, this is the detailed debug information:  Unfortunately, all this is worse than Chinese to me. Any clue where the error may be, and what to do to fix it, please? Many thanks in advance! Titel

Is this the equivalence? <dtml-var day fmt=%02i> <td tal:replace="python:'%02i'%item['day']> or exists other way? Greetings.

Changing the 'default-zpublisher-encoding' setting solved the problem but I would have to convert hundreds of iso8859-1 html pages... I have already recoded the XML inside a Python script where I think it will be easier to use any magic zope trick... so I'm asking a way to avoid changing zope.conf to produce this simgle xml file... Python script test.xml: request = container.REQUEST xml = [ ] xml.append('<?xml version="1.0" encoding="utf-8"?>') xml.append('<lista xmlns:metal="http://xml.zope.org/namespaces/metal" xmlns:tal="http://xml.zope.org/namespaces/tal">') xml.append('<item palavra="%s" id="%s" />' % (container.sqlPalavras(ID=id)[0].Apelido, id)) xml.append('</lista>') print unicode("\n".join(xml), 'iso8859-1') return printed I'm using Zope 2.9. Thanks in advance for your help and time, -- Luiz Fernando B. Ribeiro

accelerating Zope restart
by egf05＠doc.ic.ac.uk 31 Aug '06

Hi, My Data.fs is huge (21GB) because it contains many video files. This is not a problem in itself, however, I recently had to reboot my machine and now zope takes around 20-30 minutes to restart. Is a fstest automatically done ? How could I accelerate the restarting, if possible ? Thanks a lot for any advice, Eric

Accessing MsSQL from Zope blocks
by robert rottermann 31 Aug '06

31 Aug '06

Hi there, this is not really an Zope Questions, I just hope somebody of you cold give me a hint. I already asked egenix (as we are using mxODBC) they could not think of a good reason. (but said to try a comercial odbc bridge). thanks for any pointers. robert using mxOdbc our database application embeded in zope often blocks when executing a simple statement as the following: query = "select fieldValue from tblATicketDetailDynamicForm \ where ticketDetailNoFk in (1683)" calling sql_q_nil(query) (from the following class) sometimes just never returns. The problem seems to be, that after a certain amount of queries MsSQL is in a state, that it does not allow any access to the querried database. what we do in our application is: - get a RedDbQuery object (class at the end of the posting) - execute the statement with RedDbQuery.sql_q_nil(query) - release the connection. this approach worked fine using MySQL. However we did not cross any OS bounderies and did not use ODBC. we are using: mxODBC Zope DA 1.0.8 License Information: 1 Zope Instance License for redcor <robert(a)redcor.ch> [6522021#1] SuSE 9.3 UnixOdbc 2.8.8 freetds 0.64 class RedDbQuery: "All queries are routed through this class." def __init__( self ): self._connection = getConnection() #print 'getConnection() returns', _connection self._cursor = self._connection.cursor() #print 'cursor() returns', _cursor def dispose( self ): releaseConnection( self._connection, self._cursor ) def cursor( self ): return self._cursor # # query level zero -- the one and only query execution method: # def sql_q_nil( self, query, verbose = None ): "Generic SQL query, expecting no return." if verbose: print( query ) r = self._cursor.execute( query ) #print 'execute() returns', r return r more methods ..

LocalFS cut and paste across LocalFS instaces
by Dennis Allison 31 Aug '06

31 Aug '06

I have a zope system (Zope 2.9.2) that needs to be able to cut and paste between different instances of LocalFS. Specifically, I have two LocalFS instances, LFS1 and LFS2. The two local files systems are disjoint and image different parts of the local file directory tree. What I need to be able to do is to cut and paste files and directories fom one instance to the other. The clipboard object appears to be missing adequate contest to cut and paste across instances. Has anyone modified the LocalFS product to handle, say, cutting a a file from LFS1 and pasting it into LFS2? --

Packing Data.fs
by Mark Gibson 31 Aug '06

I know zope makes a copy of Data.fs before packing. Is it possible to specify a location other than <zope>/var to place that copy? Mark
