ZSQL methods do not pick variables up out of the name space because
the possability of unintended collision with database variables is
considered too high. So ZSQL forces you to be fairly explicit
about which variables you are passing.

I wonder if you could put your content in a mountable
storage and just periodically copy that storage down
to the development machine, and similarly periodically
copy the master storage (containing the ZClasses) up
from the development machine. If your products
are Python products you wouldn't even need a mountable
storage.

Zope uses the __setstate__ method for handling this
case in Python products. I think there's a howto somewhere but I'm
not sure. If not you can find examples of calling it in
the Zope sources. For ZClasses the objects get all their
info from the ZClass, so you generally don't run into upgrade
problems (though people have run into trouble with properties
they have tried to delete hanging around on existing instances).

Hi I'm looking at running Linux 6.1 and zope on a dual processor P90 Dell
powerEdge server, 128Mb RAM. Is this a viable proposition for hosting, I'm
not anticipating millions of hits?? I realise it's not the fastest thing in

sort of load will it handle, hits etc? Does Zope take advantage of the Dual
processors? What improvement is there over one processor? This box can be
upgraded to P166's what would be the improvement? Is anyone out there
running Linux on Dell EX590-2, can I expect lots of problems or easy to
set-up? Pointers to sites with more information would be appreciated.
I haven't got it yet, so want to find out more before I waste to much
time/energy/money on it.
Thanks for any help/advice you can offer.

As far as I can tell from a quick scan of the source, the precondition
is an object that is called just before the file object is rendered.
It can raise an exception, in which case the object will not get
rendered. I could swear I read that documented somewhere, but I
can't find it. Someone should submit a doc patch for the API help
pane. I'd do it, but I haven't gotten around to learning how the
help system works yet so I don't know what file to patch <grin>.

A Vocabulary allows you to associate an arbitrary method of parsing
input text into words for the purposes of cataloging and searching in
text indexes. The default Vocabulary uses the original Splitter.c
word parser, which is very English centric.

Subject: [Zope] Zope in single thread mode during DTML rendering
A collegue of mine succeeded today to implement an infinite DTML
loop. That happens ...
However, during this loop, Zope did not respond to any request.
Effectively, it was in single thread mode.
Zope 2.1.6 Binary Distribution for Sparc Solaris 2.6
ZOracle DA, DCOracle, Oracle 8.1.6
After several minutes, Zope reported an "infinite recursion in document
template" and the world awoke from its sleep.
I was unable to reproduce this at home, though:
Zope 2.1.6 Source Distribution on Linux 2
No database connections.
Hugh, I have been lying:
I just removed the "-D" from the Linux start script,
and Zope blocked during the infinite loop.
The behaviour is not related to the "-D" set or unset.
It just blocks sometimes and at other times, it does
not.

Subject: [Zope] Confusing "sqlvar" error message
Today, I analysed a confusing error message from "dtml-sqlvar".
SQL query template:
....
<dtml-sqlvar "_[name]" type=string>
....
reported: "missing input variable: _[name]"
Of cause, I did not expect that such an input variable should
be necessary and I suspected the DTML parser not to
see the "..." around "_[name]".
After analysis, the explanation was simple:
SQLVar.render is a bit stupid in its error handling:
try:
expr=self.expr
if type(expr) is type(''): v=md[expr]
else: v=expr(md)
except:
if args.has_key('optional') and args['optional']: return 'null'
raise 'Missing Input', 'Missing input variable, <em>%s</em>' % name
This error handling is only senseful for "type(expr) == type('')",
i.e. for plain variable access.
For true expressions, the original exception would be
*much* more useful.
In my case, unwrapping the "try ... except ..."
produced "KeyError: FOLLUP_UP",
an obvious type (FOLLOW_UP rather than FOLLUP_UP).
Thus, the above exception handling should become:
except:
if args.has_key('optional') and args['optional']: return 'null'
if type(self.expr) != type(''): raise
raise 'Missing Input', 'Missing input variable, <em>%s</em>' % name
I will put it into the collector.

Someone else already told you, that you must create a parameterless
method (it need not necessary be named "PrincipiaSearchSource")
that returns the files content.
You may not need to keep the rendered version around but
may be able to extract the plain text on demand.
I think, there is a "word.dll" that provides access to
MS Word from applications. Alternatively, you could
control Word via COM.

Almost surely, the "in" tag does not call a callable object
(because it does not expect, they could be callable).
You, therefore, get the method itself.
It is identical for all records.

For unknown (but strange) reasons, at least earlier Zope versions
(up to 2.1.6), sometimes place the URL of the missing resource into
an HTML comment. Therefore, you will not see it in rendered problem report,
only in its HTML source.
Thus, follow the hint: tell your browser you want to see
the HTML source of the error report.

In the Squishdot Product I discovered this:

Readme.__roles__ = None
This one seems to add a README tab. If you have a README.txt file in your

From: gyst@nfg.nl (Guido A.J. Stevens)
Date: 05 Aug 2000 14:22:30 +0200
I'm hunting down an arcane problem in one of our Zope sites and find
myself hitting new and wildly diverse problems every day. I hope
somebody can point me in the direction of some solution strategies.
Main suspect is a corrupted Data.fs.in file. How can I audit and
repair it?
problem A: access denied vs. KeyError
============================
For starters, we built a website with a lot of custom programming. I
created the NFGnav product
http://www.zope.org/Members/gyst/NFGnav
and my partner built a collection of ZClasses.
All this was Tested And Working Fine (TM).
Since some weeks, part of the site gives an 'access denied' error. We
had to shut down that subtree. Strange thing is, it also gives access
denied for the manager/owner logins of the site - that's me and I
really have access to everything. What is even stranger, is that when
I logon as superuser, I get a KeyError instead of an access denied
error.
=> Question: which parts of zope would be prone to denying access to a
privileged user, while generating KeyErrors for the superuser?
problem B: hanging zope thread zombies all zope sites
========================================
While debugging this problem, I found a strange correlation with
another problem we're having: zope threads consuming 99.9% CPU. Now
and again, a zope thread hangs. All zope sites are dead. I have to not
only restart zope; I have to stop zope, restart apache, and start zope
again to get rid of the hanging thread and get the zope sites alive
again.
As soon as I start digging around in the buggy site, the number of
thread crashes jumps up. In combination with the problems we're having
with that site itself, this suggests two possible causes:
1) ZODB curruption. We've had a complete server crash 3 weeks ago and
it is quite possible the ZODB isn't 100% healthy. In my zope
installation I found a utility 'bbb.py' to audit data storage
files. Alas, it is of no use:
| zeno:/usr/lib/zope/utilities# python bbb.py /var/lib/zope/import/www.intratuin.nl.zexp
|
| The input file is not a ZODB 2 database file.
| This script only works with ZODB 2 (BoboPOS) data or export files.
=> Question: is there another utility for checking and repairing
object stores?
2) Another possible cause would be an infinite loop in one of our
custom scripts. To try and debug this I wanted to import a copy of the
offending site into one of our testlab machines. However, on importing
the zexp file I got:
<STRONG>Error Type: TypeError</STRONG><BR>
<STRONG>Error Value: ('len() of unsized object', <class Shared.DC.ZRDB.DA.SQL at 845bd28>, None)</STRONG><BR>
<!--

File /usr/lib/zope/lib/python/ZODB/ExportImport.py, line 284, in importFile
TypeError: (see above)
I get the same error if I export another part of our production zope
installation and try to import it to another test machine.
Which points back into the direction of a file corruption again,
doesn't it?
=> So, what can I do about it?

The Zope quick reference lists the following methods
for the stock folder object:
manage_copyObjects(self, ids, [REQUEST, RESPONSE])
manage_cutObjects(self, ids, [REQUEST])
manage_delObjects(self, [ids, REQUEST])
manage_pasteObjects(self, [cb_copy_data, REQUEST])
For the life of me I can't get copy|cut and paste
to work even for the simplest of examples. I've
tried snippets like the following (embedded within
a DTML method in a folder) but to no avail:
<dtml-call "manage_copyObjects(['subobjectid']">
<dtml-call "manage_pasteObjects()">
<dtml-call "manage_copyObjects([_['subobjectid']])">
<dtml-call "manage_pasteObjects()">
Can someone shed some light on my misunderstanding?

All,
Doing the text pulling from COM is *SLOW* to say the least, You'd probabnly
be better converting them to RTF and then using something like OmniMark to
convert to XML.
That way you'd have the best of both worlds, including something you can
render to HTML when zDOM/zXSLT becomes a reality.
I already do this and it's fast enough at the conversion, a 500k doc takes
about 2 seconds.

So true, the solution is to define an __init__ class in the brain class,
then use that to populate "self".
class PackageEvent:
"""Package Event Pluggable Brain"""
def __init__(self):
"""initialize"""
self.__dict__['eday'] = self.eventday()
def eventday(self):
return
DateTime(apply(time.mktime,self.eventtime.tuple()[:3]+(0,0,0,0,0,-1
)))
Now 'first-eday' works.

Hi,
I'm having problems with adding Properties to a ZClass propertysheet.
I always get an IndexError (no traceback, sorry) when I've hit the Add button.
There are no special characters in the name ('Daten').
Does someone know what could be the problem?

Date: Sat, 5 Aug 2000 16:00:29 -0400
charset="iso-8859-1"
Zopistas,
Maybe I'm making this harder than it needs to be.
I want to set up a membership system for the site I am developing with Zope.
I do not want to "restrict" any part of the site - instead I want a user to
login (at their convenience) and then extend the "menu" options based on
their group membership. If a user is not logged in - no problem, they just
won't be able to view the advanced options - they'll still be able to surf
the site (I want to maintain my user list in an external database as well).
What is the best tool in Zope to accomplish this? After searching the site,
I find there are several products - ACL Users, GUF, and LoginManager. Is GUF
deprecated (The intro tends to give me this feeling)? Is LoginManager the
way to go?
It also appears GUF is more tailored toward restrictive authentication (I've
already perused the "Using GUF with an SQL Database" how-to). I want a user
to login (via HTML form/cookie) whenever they like, and get presented with
additional menu options (based on their AUTHENICATED/GROUP status). Not have
them try to access a "restricted" page (or type "manage") and get a basic
authentication login box to get in.
As far as LoginManager itself is concerned, I assume it requires ZPatterns.
However, the Zpatterns install instructions are *very sparse.* How do I get
the thing set up? Here's verbatim from the ZPatterns docs:
-----
After unpacking the ZPatterns product, you will need to build this [c]
>extension using the included Setup file in the ZPatterns directory.
-----
How do I use the "Setup" file?? With the command "python Setup"? It doesn't
say *how* to use it.
-----
Please follow the standard procedures for building a Python module on your
platform. (On Unix-ish systems, this usually consists of copying a
Makefile.pre.in to the directory, then doing a make -f Makefile.pre.in boot
>followed by make.
-----
What are these standard procedures?? I built Python itself with
"configure|Make|Make install". Where do I get this "Makefile.pre.in" file in
the first place, from my Python src/build directory?? Correct me if I'm
wrong, but there's usually some kind of script file to run that get's things
going, or a "configure" script. I find none of this in the
lib/python/Products/ZPatterns directory after I untarred it.
So, I'm basically stumped. It doesn't appear GUF will do what I need, and I
have failed on multiple attempts to get Loginmanager/ZPatterns installed. If
someone could point me in the right direction on this I sure would
appreciate it.
Thanks much,
-Darin Lee

If I'm running current stable versions of Zope and Zope-MysqlDA, do I
need to consider threading issues or are these safely abstracted away
in the DA?
"Luis Cortes" <LCortes@IMEME.NET> writes:

I'm running the Debian frozen release, i.e. 2.1.6 with security
patches. Do you have any specific references on the thread problem? I
find nothing on it in the changelogs I've found. Do I need to go to
2.2.0 for this?
A seach on 'threading problem' turns up a hornet's nest of deep
technical shit. Most of those mails are a year old, is this still an
issue? As a developer, do I need to understand threading issues when
developing database accessing products, or may I safely assume that
threading, locking and transaction semantics are handled between the
Database Adapter and Zope itself?
I found a mail that says I should run Zope single-threaded when using
MySQL: http://lists.zope.org/pipermail/zope/1999-July/006487.html
Checking my installation, I find I have no threading option activated,
which means I'll be running the default number of 4 threads. What will
my server performance look like if I reduce this to 1 thread? Not
that I'm having such a wonderful performance now, having my pager go
off every hour :-(
Is there a way to allocate different threads to different SiteRoot
virtual websites, so I can lock a single site in a single thread but
let my installation as a whole still retain some multi-threading
performance?

| Good evening.

This is easier than you might think:-
Step 1: Do not register your 'sub' class(es) in your __init__.py
Step 2: In your container class import your sub class manage_add function(s)
(not sure if this is really needed, but, I do it for completeness).
Step 3: In your container class add:-
meta_types=({'name':'Sub Product', 'action':'manage_addSubProduct'},) # Sub-ob
ject types that are specific to this object
You can add as many as you like...
Step 5: Optionally add a meta_type to your sub class (if you haven't)
Step 6: Optionally add icon='thisIcon.gif" into your sub classes so they get
pretty icons.
Copy over new Product, and Restart Zope :-)

Did u upgrade an existing zope instance with the new distribution, or was
it a clean install? Did you install the SiteAccess product? This sounds
like the error you get with an old SiteAccess object in the new zope2.2.
You need to upgrade to the new SiteAccess.

Thank you for the hint.
I had purged my old zope (dpkg --purge) but it seems something was still
there hanging around. I did an "rm -rf /var/lib/zope /usr/lib/zope" and
reinstalled zope and it worked!
I then tried to install the package "zope-siteaccess" from Woody but it
depends on zope (>= 2.0.0-2) which is not available :|
I'm sort of new to zope so may I ask, Do I need this "zope-siteaccess"
package from Woody?
Thank you,

You only need the siteaccess product if you wish to server multiple domains

Precondition
Allows you to specify a precondition for the File. A precondition is a
method or document which is executed before the File is viewed or
downloaded. If the precondition raises an exception then the File cannot
be viewed.
This is from the Help page presented when you click the 'help' button on the
'Edit' tab of a 'File' object.

Subject: [Zope] Problem with proxy role...
Date: Sun, 6 Aug 2000 16:43:18 +0200
charset="iso-8859-1"
Hi!
I'm trying to set up a site with user registration (similar to that on the
zope site), and have been using the JobBoard HOWTO as an example
of how to let anonymous users add objects. The code works just like
it should when I'm logged in as Manager, and I *have* set the proxy
role of the method that processes the form to Manager, but still, when
I try to use it anonymously, I get the message that I don't have access
to the user class... I've tried several implementations, but I don't
understand
the problem...
If the method is proxied as Manager, shouldn't it (and all
the methods it calls) have the rights of Manager? (I also tried adding
Owner, but that didn't help...) In that case - why doesn't it work, while
it *does* work for me when I'm logged in as Manager?
Can there be a standard problem hiding here? (Or, perhaps, it's
obvious?)
Any help is appreciated. Thanks.

I knew I'd read it somewhere!
First I ran through the help menu, but I must have looked at
File/Image Add and missed File/Image Edit. Then I looked at an
Image (I had no File objects handy), and when I saw that the help
tab for the Edit, page had no description of precondition, and indeed
that there was no way to set it, I figured the docs for it must
only be in the API section. But the API section does not discuss
*any* of the call paramters. So I thought it was undocumented.
Since the code supports preconditions on an Image, is this an interface
error or a design decision (the latter seems more likely)? If it's
a design decision, shouldn't precondition still be documented in
the Image api help doc?
This is an example of a systematic problem with the (very useful
<grin>) help docs as they stand: if the API docs implicitly assume
that the parameters are documented in the corresponding management
interface panel then there should at least by a cross link; and if
there are sometimes parameters that are *not* documented on the
manage page, then that needs to be taken into account somehow.

Magnus:
In setting up the JobBoard from the HOWTO, what worked for me was setting
the proxy role for both the method in the JobBoard product that processes
the form to "Manager" (Product
at/Control_Panel/Products/JobBoard/job_board_entry_add); as well as the
regular method that processes the form to "Manager".
The HOWTO seems to indicate that only the regular method must be set to
proxy, i.e., "Important:The "entry_addProcessor" must be set to "Manager"
proxy for it to work." When I followed only this instruction, I ran into
the same problem that you did.
However, while this works for me, I am not sure that this is the zen way of
doing things.

This little DTML code is supposed to be generic for alla folder is the profil folder.
What I want to do is a to have a next folder and previous folder in evey one.
/profil/
/folder_XHJSD
/folder_GIEHG
/folder_OWKD

Document_html is acquired in all folders in the profil folder.
I started doing something like this:
<dtml-in "profil.objectValues(['Folder'])" sort=id>
<dtml-var id>,
</dtml-in>
... and this returns: folder_XHJSD, folder_GIEHG, folder_OWKD....
What I want to do is something like this:
<dtml-call "REQUEST.set('thisid',_.string.split(URL,'/')[-2])">
<dtml-in "profil.objectValues(['Folder'])" sort=id>
<dtml-if "_['id'] == _['thisid']">

.... but this returns

They picked the wrong free UNIX platform. Linux has a whole lot of
machines installed, but, not too many of them would be deployed in an
Enterprise environment, where people would be happy to pay money for
licenses.
An OS heavily promoted by one specific individual who doesn't really believe
in commercial software doesn't seem like the ultimate platform to aim
high-priced internet application software at.
I think you'll find that Sybase the DB will still be released for Linux,
just not their Internet Application Suite, which is a different kettle

This how-to was written before Zope 2.2.0 was released. 2.2.0 involved major
security policy changes.

Not in 2.2.0. Now, AFAIK, you have to explicitly set proxy roles for each
method.

Whilst I would ordinarily agree with some ofthis, in the case of Sybase, I have to disagree. I work primarily at a
company called Hewlett Packard, not exactly a small company. We have service contracts with Sybase on NT and HP-UX
(suprise). After over six months of trying to get sybase to work with us on getting the appropriate libraries to us to
compile the SybaseDA on HP-UX, and then being told it must be faulty programming on the part of whomever developed the
adapter, we gave up.
This experience has left a real bad taste in my mouth regarding sybase.
The good side of the coin, is that we dumped Sybase for the, and moved to straight ZODB. :)
The claim that Linux is not deployed in Enterprise environments is uninformed at best. The most recent announcement came
from Google, which claims 4000+ Linux servers. Clearly an enterpise environment.
( http://www.internetwk.com/lead/lead060100.htm )
HP is migrating many, many Enterprise Servers from NT and even HPUX to Linux boxes, in addition to porting Linux to
their hardware (PA-RISC), and their tools to Linux. I am personally aware of over 600 machines deployed in that
particular enterprise, and the number literally grows weekly.
And, of course, there is IBM.

While I don't mean any offense, your characterization here is both unwarranted and unfounded. ESR and Linus (not sure
exactly whom you refer to) both believe in commercial software just fine.
In addition, if you look at the largest promoters of Linux, you will not find any one individual. Rather, you will find
an array of companies, of all sizes; from ISP's to ol' Big Blue. IBM, for example, is in the process of porting most
everything they have to Linux. And they do it for commercial reasons.

and where to find a tutorial or manual of ZODB.
I am new to POS ,
Is there any stuff that will give me a senerio of
working with POS, such as ZODB.
Thanks a lot.

err no. Read again... "not deployed in Enterprise environment, where people
would be happy to pay money for..." as opposed to deployed where people
want stuff for free - or as free as they can get it. Face it if you're
doing web stuff using Zope (or anything else), you're not looking to go and
pay Sybase for something just as good, with a hefty price-tag. You still
have to pay developers, and 'commercial' stuff usually attracts people at
twice the rate of the going Open Source developers.
PHP is firmly entrenched as the ASP of Linux at this stage and it's going
to take a very long stick and a very firm place to stand to shift it.
| And, of course, there is IBM.
Who do a lot of open stuff, with FreeBSD as well. But marketing requires
a Linux presence these days... mustn't let that share price slip.. :-)

| While I don't mean any offense, your characterization here is both unwarranted and unfounded. ESR and Linus (not sure
| exactly whom you refer to) both believe in commercial software just fine.
Actually referring to RMS...
| In addition, if you look at the largest promoters of Linux, you will not find any one individual. Rather, you will find

| everything they have to Linux. And they do it for commercial reasons.
One wonders if Oracle's Linux product has actually recouped them the
development costs. Most of the larger Linux promoters are trying to get a
leg into the 'smaller' market that was dominated by NT. If they can offer
their products on hardware that doesn't cost more than a house, then they
have opened a new market. Linux is obviously a means to an end here. They're
trying to make a sale, they don't particularly care about Linux.

For caching, IE is one of the better behaved browsers
Check the content of your "Temporary Internet Files" directory - this
will show when the cached documents expire.
You might find you need to manually purge your browsers cache after

Also, xmlrpclib will marshall a class instance as a dictionary, using
it's __dict__.
This applies to instances of python classes, but not extension
classes. Fixing this would be a bad idea: ObjectManager.objectItems
would try to return your whole database.

Hello,
I created a form to allow users to change their own passwords. I
hate the idea of giving them all "Manage Users" permissions, but ok
whatever. But "acl_users.manage_users('Change', REQUEST, RESPONSE)"
won't work unless the user has "View Management Screens" permissions.
Not only does this make no sense, because the procedure doesn't involve
viewing management screens, but it would be absolute insanity to give
all of my users those permissions, because then they could go in and
delete users at will! There has to be a way to do this, but can I get
around this problem without additional products (i.e. Login Manager)?

Python is a glue language, so it surely is possible. Just create an
external method for Zope, and in that you can call your program. Look
into the Python documentation for further information. (os.system, I think)

I created a ZClass called "Product" with Dataskin as baseclass.

Under storage for the rack I selected the newly created Product ZClass.
My product ZClass needs to query both a RDBMS and the ZODB for
attributevalues. At this point I get lost.
I guess i should add an attributeprovider plug-in???
What should go into the fromexpr and attrsexprs properties of the

My site has a number of DTML Document objects which simply redirect the user

other. The text of the document is simply
<dtml-call "RESPONSE.redirect(dest)">
and dest is a property automatically set on creation.
I need to provide a simple form to allow users to edit the value of this
property, so I have to retrieve the current value of the property. However,
whenever I try to get hold of this with anything like <dtml-var

Do you mean you want to use a Python Method (in the sense of a methodish

Subject: [Zope] Zope is slow on a windows 2000 server
Mime-Version: 1.0
Content-Type: text/plain; charset="iso-8859-1"; format=flowed
Content-Transfer-Encoding: 8bit
Hello,
I've been using Zope on a Linux box without any problem this last month. I
now have to move the Zope server to it's final location, which is a Windows
2000 server (it's not my choice ;-(
I am trying to get the user authenticated based on his IP address to allow
everybody on the subnet we are here to access the Zope server, but not
other IPs. This works fine except it is really slow (about 5 seconds to go
to an object to start downloading). I've tried it on a clean Win2k box to
check if I had a problem with my configuration, but it didn't change anything.
Here are the basic operations I did. First create a local role "test" in /
that has the same authorization as anonymous. Then disable any
authorization for this Anonymous user. Create a user in acl_user which
don't have a password but has a domain entry 192.168.0.* and the role
"test". Now when I connect from the 192.168.0. subnet, I have access to the
Zope server, but it is very slow to answer. When I add a user that has to
log in (password instead of IP check), it goes much faster.
I am using Zope 2.2.0 with the built-in Medusa web server.
As I am with the Win2000 questions, is there a way to configure IIS to
behave like Apache an the rewrite rules?
Thank you for your help.
Best regards,
Gérard Métrailler Jr.

ImageFile objects do not (like ZODB stored Image objects) generate an IMG tag
when called. Image object, when called, generate an IMG tag that points the
browser to the correct address to retrieve tha actual image.
With an ImageFile object, you need to construct the tag yourself. If this
class has an instance foo, with this ImageFile attribute chooser, and the
instance foo is stored in the root of your Zope ZODB, you need to point the
browser to http://yoursever/foo/chooser. So your DTML needs to generate the
following HTML:
<img src="http://yoursever/foo/chooser">
I don't know enough about your DTML, but if it is another attribute of the
same class, you could use one of the URLx REQUEST variables or something to
construct the URL for the image. Also, absolute_url() called on the foo
instance may also work for a base URL.
Hope this helps.
