We have similar needs, altough not necesarily competition driven. We need to move onto more consulting work which will require more documentation for our paying customers.

I wouldn't say poor documentation is a cost, but it is a contributing factor to high costs. As an example, it took me about three man-days (over the course ofa week) to find enough documentation on the new Linux software RAID to get it right. ALl the faqs, howtos, and source docs were out of day. In fact, there were three 'official' RAID homepages, each with a different version of the software at various points in it's development stages and for various kernels. It was maddening. I know how you feel. Trust me, we're on it. We're not sitting back and ignoring all of these threads on documentation. There are also some recent developments that cannot be discussed at the moment (think bound sheets of paper) that will bring us into a serious light with people who like docs. -Michel

Good news however is that we are working on some new default content that comes with Zope. This will include a very friendly novice oriented 'first page' with pointers to a tutorial, the revised quickstart material, and all of the online resources. And it will be ZCataloged so users will get an example right away of using the Catalog with Zope content. -Michel > Boris Borcic > -- > "Hope achieves the square root of the impossible" > > _______________________________________________ > Zope maillist - Zope(a)zope.org > http://www.zope.org/mailman/listinfo/zope > > (To receive general Zope announcements, see: > http://www.zope.org/mailman/listinfo/zope-announce > > For developer-specific issues, zope-dev(a)zope.org - > http://www.zope.org/mailman/listinfo/zope-dev ) >

ZSQL method - PostgreSQL error
by Constantin Teodorescu 19 Aug '99

19 Aug '99

A strange error I have encountered today : Environment: RedHat 5.2 i386 Linux Zope 2.0.0b4 running with ZServer (not with apache) PostgreSQL 6.5.1 ZPyGreSQLDA-0-0-3 PyGreSQL v2.4 I am defining a Z SQL method in order to select some records from 3 linked tables. If the query will return only two fields (date and value) everything is ok, I can see the results, publish them. If I am selecting 3 fields from the tables (date, explanation and value) I am receiving the error: Zope has encountered an error while publishing this resource. Error Type: pg.error Error Value: ERROR: hash table out of memory. Use -B parameter to increase buffers. This is a PostgreSQL error and it's related with some PostgreSQL backend parameters. The buffers can be increased with a -B parameter. BEFORE increasing the number of buffers I have tried the same SQL select in "psql" (the PostgreSQL monitor). It succeeded!!! I have tried the same SQL select in PgAccess (the PostgreSQL graphical administration tool). It succeeded!!! The tables aren't so big (5 Mb the whole database). The strange thing is that the same query is succesfully executed by other front-ends (psql is written in "C" and PgAccess in Tcl/Tk). The default # of buffers is 64. I restarted PostgreSQL with 128 and then 256 buffers. The same result. Zope cannot retrieve that select. That means that the error could be in PyGreSQL module? Any clue? -- Constantin Teodorescu FLEX Consulting Braila, ROMANIA

In short assume I am an idiot(you >wont be so far wrong) but I need to get something working pretty quickly, >and I'll make it graceful later. Yep, ZCatalog comes with Zope 2.0. You'll probably want to check out http://www.zope.org/Download/ZCatalog/ZCatalogTutorial (which I believe is also in lib/python/Products/ZCatalog/ZCatalog.txt in your Zope distribution) In general, to use it with DTML Documents should be pretty straightforward (I think). Create a ZCatalog object (possibly in your Zope root). For any Property you set up in your DTML Doc that you want indexed and searchable, you need to enter that property name in the Indexes tab of the ZCatalog. (You choose FieldIndex if you want the field to contain one discrete value, regardless of spaces, TextIndex if you want a full text index that you can search). You can use the Z Search Interface, as Michel mentioned in his reply to get going. The tutorial above lists some DTML for searching. I've used it like this: <dtml-in "Catalog({'metatype': 'MyZClass', 'category': 'top_stories'})"> <dtml-var title> </dtml-in> Will list the titles of any "MyZClass" type object that has the category property set to "top_stories". There's no one way to use ZCatalog and create the searches you want. It's pretty flexible, but that flexibility also means that it's a little more complicated to get started with until the docs catch up. Playing around with a ZCatalog object and a ZSearch Interface will get you going, and you can probably find out some more of what's there by checking out the ZCatalog source code. Another way to help get acquainted would be to check out the beta Zope2 site http://www.zope.org:18200/ Every page has a DTML Source link that lets you see how the page was produced. Kevin

(bug?) long result sets sometimes return wrong mime-type "Application/Octet-Stream" "Application/Octet-Stream"
by Heiko Stoermer 19 Aug '99

19 Aug '99

I think I discovered a bug (might be even two, now that I think about it): I have a simple ZSQL query that returns some 500 rows. I created a standard search interface (size=50), which of course produces the "next x results" hyperlink at the bottom of the table. Now: 1.) the Hyperlink always says "Next 1 results", where it should say 50... (or whatever I put in the "size" parameter of the search interface's "in" tag) 2.) if I move forward to, say, row 150 or so, using the link sometimes I don't get a page displayed but the Navigator-dialog "save as ... (application/octet-stream)" appears. (I can certainly save the file to disk, reopen it via "file-open" and it gets displayed correctly. of course it does: a "file-open" does not transmit MIME-Types...) If I change the "size" parameter in the search interface to another value (e.g. 200) I get the "save as.."-dialog right away... Is this problem already known, and maybe even solved yet?
