RE: [Zope] ProxyPass Problems
by Baker, Dennis [sjmr] 28 Jun '00

The idea was to have http://mysite.org go to one part of my site, and https://mysite.org go to a different section of my page. When you request a page using http:// the request comes in on port 80 is non-encrypted html. https:// requests go to port 443, and are encrypted. So the idea is to have Apache ProxyPass the secure pages (Port 443) to the Secured pages. All better now... I didn't pay attention to the existing VirtualHosts in httpd.conf and paid for it. > -----Original Message----- > From: Peter Sabaini [mailto:sabaini@niil.at] > Sent: Tuesday, June 27, 2000 6:12 AM > To: Baker, Dennis [sjmr] > Cc: 'zope(a)zope.org' > Subject: Re: [Zope] ProxyPass Problems > > > > i dont know much about ssl but wouldn't you want to pass / --> > https:// instead of / --> http:// ? > but then again i dont know a thing about ssl... > peter > > > On Mon, 26 Jun 2000, Baker, Dennis [sjmr] wrote: > > :I'm having a problem with getting ProxyPass and SSL to work. > I followed the > :How-to on Using Apache with ZServer, and unfo's How-To on > :Apache+ZServer+SSL.

If an SMTP server detects a problem, it rejects the SMTP request. If the requester is an SMTP server, it sends an error message back. If the requester is something different, e.g. a Zope sendmail tag, it must do something about the problem -- e.g. raise an exception. Dieter

Well, it's NOT a production environment at this point. I just thought I'd see if I could play with it until my LinuxPPC 2000 CDs arrived and I could put it on a Mac where it BELONGS. :>) I'm looking forward to attempting some benchmarking of Zope on a 533mhz Pentium III vs a Mac 200mhz PPC 604e.

In Zope 2.1.0, it was not at all easy to use the HTTP streaming. Many proxies and IE require the Content-Length header to be correct. To set a correct "Content-Length" was not a problem. However, ZPublisher.HTTPResponse reset it afterwards to 0, leading to very strange effects in various situations (i.e. with IE and some Proxies). We finally settled it in the following way: RESPONSE.setHeader('Content-Length',length) RESPONSE.setHeader('transfer-encoding','binary') # to prevent RESPONSE.__str__ to overwrite "Content-Length" RESPONSE.headers['Content-Length']= length # now do several "RESPONSE.write" I am not sure, whether 2.1.6 or 2.2 still requires this strange code sequence. For Zope 2.1.6, we detected a nasty ZServer bug with the streaming protocol: missing thread synchronization. As a result, browsers got a non-deterministic part of the image. Very nice effects.... DC told me, that this bug is fixed in the CVS and for Zope 2.2. Thus, do not use the HTTP streaming protocol for the standard Zope 2.1.6 distribution (or be ready to patch ZServer). Dieter

ZODB or not ZODB?
by Casey Duncan 28 Jun '00

28 Jun '00

I am implementing a document Library using Zope. It has an exhaustive index with several thousand topics in an outline residing on a PostgreSQL database. This works well and I like it. My question is where is the best place to store the documents themselves? They will be static HTML documents ranging from 1-50Kb in size roughly. There will probably be at least 10,000-15,000 of these documents in the library once all is said and done. In my mind I have three options: 1. Store them on the filesystem. 2. Store them in a PgSQL table as blobs. 3. Store them as DTML Docs in the ZODB. I would like to eventually have full text searching capabilities, so that makes #1 less attractive (I would likely need my own Python method to do it). #2 is somewhat of a pain to implement due to limitations in the PgSQL row size and text searching would be slow. With #3 I could in theory use a ZCatalog to implement the searching, so that is done for me. Is ZODB up to the task of storing this quantity of objects? What problems might I run into? Is it a wise idea, could a data.fs file of this size (~3-400MB) become too easily corrupted? Should I use a separate data.fs file just to store the documents (ie using mountedFileStorage)? Or is it better to use method #1 or #2? Information from anyone with experience in this regard is greatly appreciated. -Casey Duncan caseman(a)mad.scientist.com

I have a folder call tabledef which use dtmldocument to keep some field definition like its label, size, default value, help text etc. Which I would like to generate the data entry form for it. The data will be stored as object properties, so If I generate a edit form, then I should get the property, lookup the field information in tabledef folder, and get the label, size, information from there.

Problem with > 1 ZCatalog search on same page
by Jeff Sasmor 28 Jun '00

28 Jun '00

Hi Zopistas- I have problem that I hope that there's an answer to. Perhaps this has been covered on this list already, but I couldn't find it by searching the NIP archives and 800+ results for "ZCatalog" was mind-numbing..... I have two ZCatalog searches on the same page (in the same DTML method). Each has different fields so they have different numbers of results displayed in two tables. This works just fine. What's wierd is that the 'batch_size' code interacts between the two-- if the size of the first table's set of results is < batch size and the size of the second table's results is > batch size then the second table has a "next N results" link. If I click this then the second table dutifully displays the next data set. BUT- the first table just displays the LAST item it had displayed before. >From a quick glance at the way that ZCatalog works, it seems as if this behaviour could be correct; and the batching code in the ZC can't handle more than one set of results associated with a single DTML method. But I am by no means sure of my interpretation of the python code here. Anyone have any insights? TIA, Jeff Sasmor jeff(a)sasmor.com PS. For those Zopistas who are MontyPythonistas: I get to see "Eric Idle exploits Monty Python" tonite (weds 6/28) at Carnegie Hall in NewYawkCity. They promise lumberjacks, etc. This goes on tour to some cities in the US this summer. Bought these tickets months ago so have the 4th Row Orchestra! I hope this is as good as seeing Monty at NYC's Civic Center <dtml-more-years-ago-than-I'd-like-to-admit>. John Cleese stepped on my foot whilst selling albatrosses (?) at that one. But I digress...
