I'd like to incorporate it into 1.10.3... It has nothing to do with simple math, but everything with the interpretation of None compaired to 0's. Something that was implemented wrongy in python 1.5.1, and fixed in 1.5.2. This change brought out a bug in the code, which hitherto had managed to miraculously work anyway. 1.10.3 is meant to run with python 1.5.1, not 1.5.2, and has only been tested with 1.5.1. There are other problems concerning running Zope 1.10.3 with version 1.5.1 than this one, like Netscape Publishing, FTP uploads and WebDAV being broken. If you insist, here is a context diff from the CVS you could apply, it probably has slightly differing line numbers, but you should be able to apply it to DT_In.py anyway, as patch will correct for this. It basically replaces all occurrences of None within calls to the method 'opt' with 0: *************** *** 531,537 **** try: if previous: if first > 0: ! pstart,pend,psize=opt(None,first+overlap, sz,orphan,sequence) kw['previous-sequence']=1 kw['previous-sequence-start-index']=pstart-1 --- 531,537 ---- try: if previous: if first > 0: ! pstart,pend,psize=opt(0,first+overlap, sz,orphan,sequence) kw['previous-sequence']=1 kw['previous-sequence-start-index']=pstart-1 *************** *** 547,553 **** # there are more items, without actually # computing a length: sequence[end] ! pstart,pend,psize=opt(end+1-overlap,None, sz,orphan,sequence) kw['next-sequence']=1 kw['next-sequence-start-index']=pstart-1 --- 547,553 ---- # there are more items, without actually # computing a length: sequence[end] ! pstart,pend,psize=opt(end+1-overlap,0, sz,orphan,sequence) kw['next-sequence']=1 kw['next-sequence-start-index']=pstart-1 *************** *** 563,569 **** validate=md.validate for index in range(first,end): if index==first and index > 0: ! pstart,pend,psize=opt(None,index+overlap, sz,orphan,sequence) kw['previous-sequence']=1 kw['previous-sequence-start-index']=pstart-1 --- 563,569 ---- validate=md.validate for index in range(first,end): if index==first and index > 0: ! pstart,pend,psize=opt(0,index+overlap, sz,orphan,sequence) kw['previous-sequence']=1 kw['previous-sequence-start-index']=pstart-1 *************** *** 577,583 **** # test whether there are more items, # without actually computing a length: sequence[end] ! pstart,pend,psize=opt(end+1-overlap,None, sz,orphan,sequence) kw['previous-sequence']=0 kw['next-sequence']=1 --- 577,583 ---- # test whether there are more items, # without actually computing a length: sequence[end] ! pstart,pend,psize=opt(end+1-overlap,0, sz,orphan,sequence) kw['previous-sequence']=0 kw['next-sequence']=1 -- Martijn Pieters, Web Developer | Antraciet http://www.antraciet.nl | Tel: +31-35-7502100 Fax: +31-35-7502111 | mailto:mj@antraciet.nl http://www.antraciet.nl/~mj | PGP: http://wwwkeys.nl.pgp.net:11371/pks/lookup?op=get&search=0xA8A32149 ------------------------------------------

RE: [Zope] Tree tag and SQL methods?
by Alexander Staubo 25 Jun '99

25 Jun '99

I haven't tested this yet, but it seems sound; I'll let you know if it doesn't. :-) Now perhaps you can assist in another similar case with the #tree tag. Basically I have a two-level hierarchy of (simplified) articles and their home publication. The article database might be something like this: Title: Publication: Foo Bar Mag Bar Fnargh Times ... I seek to render a "tree" where the publication is the tree node, and the list of articles (by their title) are listed under each node. A little like the "Quick Start" thing. Click on the "plus" icon beside the publication and you get a (non-tree) list of articles. Actually I get this is, strictly speaking, a one-level hierarchy. While this structure is simple enough that could stay clear of using the #tree tag, I'd still like to try. I tried:    thinking that Query() would return the publications, and each publication would use the DTML Method Leaf to render its contents, but no.

First of all, #tree doesn't seem to handle SQL Method output the way I want -- I don't know why. Secondly, the branches_expr expression doesn't compute because obj_id isn't a known variable at this point; it should be written as  But that doesn't seem to work either.

New version of mod_pcgi
by A.M. Kuchling 25 Jun '99

25 Jun '99

I've finally gotten around to fixing the most serious outstanding problems with mod_pcgi; it is now actually usable. PATH_INFO is now set correctly, so Zope creates URL references that are reasonable, and the Authorization HTTP header is passed along so that you can actually log in. In my limited testing, everything I tried in Zope seemed to work fine using mod_pcgi. In short, you could actually start using it for real now. The code is in the usual place, ftp://starship.python.net/pub/crew/amk/new/ Please download it and try it out; I'm going to work on some Web pages and documentation for it. -- A.M. Kuchling http://starship.python.net/crew/amk/ Well, you are the best I have, Cluracan, and to say that is to say little indeed. -- Queen Titania, in SANDMAN #52: "Cluracan's Tale"

DTML batch processing variables
by Joachim Schmitz 25 Jun '99

25 Jun '99

Hi, I tried the example from the DTML userguide with my query and get wrong values for: next-sequence-size and previous-sequence-size, here is my dtml-example:        <a href="qs="> (vorherige  Adressen )</a>    E-Mail.DE hat insgesamt  Adresse n gefunden.  <H4>.   </H4> , ;   Tel:  Fax:   <a HREF="mailto:"></a> geschäftlich   <a HREF="mailto:"></a> privat         <a href="qs="> (die nächsten  Adressen )</a>   Es wurden leider keine Einträge gefunden  When for example 111 records are found: next-sequence-size is alway "1", and previous-sequence-size is "-90","-70","-50","-30","-10" everything else works as described.

CVS checkout errors?
by Alexander Staubo 25 Jun '99

25 Jun '99

List traffic is slow, so I thought I'd do my part in boosting the activity :-) Using CVS 1.9 I get lots of "internal errors" from CVS when checking out Zope. As far as I can determine, though, files are checked out completely. The error is: cvs checkout: internal error: repository string too short. Couldn't find anything in the CVS FAQ about this. -- Alexander Staubo http://www.mop.no/~alex/ "What the hell, he thought, you're only young once, and threw himself out of the window.
