Re: [Zope] Problem with cursor

Please keep your replies on the list so others can help and the discussion is archived. Knowing that the call works if called just once on a page verifies that the bug is with ZODBCDA not moving the cursor as it ought (or not caching the results...) If you must host on W2k, look at the eGenix solution.

urlencode in ZPT - newbie question
by Dominic Hiles 02 Jun '03

02 Jun '03

Hi, I have a ZPT which iterates through folders and files to produce a directory listing. However, the links to these files need to be urlencoded, in case the file names contain spaces (or other "odd" characters). I have tried the code given below, but urlencode isn't recognised ("NameError: global name 'urlencode' is not defined" : <--- snip ---> <a href="id" tal:attributes="href python:urlencode(item.getId())">  Any help would be much appreciated, Thanks, Dominic

A dead peer means that the ICP replies are getting lost. Lost, not just delayed. Is squid really saying "dead peer" in cache.log? Do you have network packet loss? Or, maybe squid isnt actually declaring the peers as dead... you would get a similar effect if you neglected to put the "round-robin" directive on your cache_peer lines, which controls how it resonds to delayed ICP responses (if this is the case then you may want to tweak icp_query_timeout for performance, but thats a different question) I am still suprised that this applies to you at all, because you ZEO server is on it own machine. right? Is there anything of interest in cache.log? What about if you turn on full debugging in squid.conf? Can you post a before and after of "Peer Cache Statistics" page in squid cachemanager CGI -- Toby Dickenson http://www.geminidataloggers.com/people/tdickenson

python locally compiled or binary distribution
by Dennis Allison 01 Jun '03

01 Jun '03

Some time ago Dieter posted a comment where he indicated that he saw a substantial performance difference using a locally compiled python vs. the python shipped with the binary distribution. Why is this the case? What sort of performance difference might I expect?

starting zope with su instead of -u
by Dylan Reinhardt 31 May '03

31 May '03

This feels like a huge newbie question, but I'm starting to lose hair and I was surprised not to find anything helpful in the archives. I want to try out DirectoryStorage. I gather you're not supposed to use the -u option and obviously I don't want to run as root. So I use something like su - -c START_COMMAND zope But then I get that message about how I can't run zope as root and should read the SETUID doc. But I'm not running zope as root and the SETUID doc is distinctly unhelpful with respect to using anything other than -u to drop privileges. Is there something basic I'm missing? I'm running 2.6.1 on Gentoo, if it matters. Thanks in advance, Dylan

how to format a lines property
by michael haubenwallner 31 May '03

31 May '03

how do i format the value of a lines property in a "Filesystem Properties Object" correct? eg: multivalues:lines=value1, value2, value3 results in just one line, not three... ZPublisher.Converters.py: file2lines wants to split on \n but no newlines are allowed in a .props file Thanks, Michael
