i did set RESPONSE.setHeader(blah blah).  my question was where should i put
this statement.  but now, i found out that it doesn't matter where i set it,
it will be in the header.  however, ie still doesn't respect the
cache-control request.  it till shows old news, which is bad, which brings
me back to square one.:(

i'm on my wits end now.  help?

[Zope] Zope + Apache on FreeBSD 4.0 problems

[jholland]

-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1

I'm having trouble getting pcgi working for Zope 2.16 on Apache 1.3.12
on FreeBSD 4.0. I had hope the BSd ports would set it up but it seems
that there is a problem of some sort with my install.

Zope.cgi produces output but kind of maimed.

I did get Zope.cgi working with IIS and NT (ugh) at work.

Any tricks or anything would be appreciated.

[Zope] I have a question on Zope 2.2

[Jonathan Desp]

Hi everybody,

I'm using Zope 2.2 on my local machine, where I constructed my data.fs, then
after I uploaded this data.fs on my hurrah.com server which use an older
version of Zope(2.1.6), then I was not able to add any DTML Document or DTML
Method, and all the DTML images was broken, as well as at my web site all
the pages was "not found" even if I was able to edit those file in the Zope
management intereface.

Anyone here know how to fix that ? If I cannot upgrade my zope on the
hurrah.com server, how I can make the data.fs compatible with the older
version.. ?

Very truly yours,

If that fails:

You could also delete the Catalog, delete the Item, and Undo the Catalog
Deletion. This has worked well for me in the past.

YMMV

You've answered your own question.  There is no end in the middle of
the path.  The publisher picks off each part of the URL from the top
down, and at each step, it asks that object if it can provide the next
one.  Look at traverse() in lib/python/ZPublisher/BaseRequest.py, or
step through the publishing process - see
.

At each step, the publisher checks to see if the parent has the child
as an attribute, and if so, continues with the object at that
attribute as the parent (so long as other conditions are met, like
permissions).

You can see this in python products:

class Foo:
 "a python product"
 ...
 index_html = HTMLFile("someDTMLFile", globals())
 index2_html = "..."
 index3_html = aFunction(mood, phaseOfMoon)

Since getattr(path.to.foo, "index_html") reaches that html file,
ZPublisher.Zope("/path/to/foo/index_html") publishes that file.
index_html could be a (badly named) method instead, which has other
attributes.  It could decide what to publish or how to allow
the publisher to traverse the path programmatically.

You don't need extra rules that look for foo.pl in the URL (what a
kluge - enforce a perl script to sit there until URLs are no more!).
For your example, script.pl could have two subobjects or other
attributes, 1234 and 2345, and the default index_html.  Or script.pl
could be a ZClass with those three as DTML methods or other
subobjects.

__bobo_traverse__ is another attribute that the object may have to
drive the publishing process, but I haven't needed to understand why
it's useful yet :)

[Zope] Delete property woes in ZClasses

[Paul Abrams]

I noticed that when you delete a property in a ZClass, it
doesn't actually delete the property in **instances** of
that ZClass! This leaves properties lying around where they
can be inadvertently acquired, causing problems that are
difficult to trace.

Has anyone gotten bitten by this, or know of a solution?

Cheers,
-Paul

[Zope] Announcing dev.zope.org

[Brian Lloyd]

Hello all,

For some time now, it has been a goal of ours to open up 
the Zope development process. Some of you may have heard 
me promise this at the Zope track back in January. Well, 
it took a little longer than I had hoped it would, but 
I'm happy to announce an important step in making that 
a reality: http://dev.zope.org.

dev.zope.org is the place for discovering, initiating, 
and contributing to work on the core Zope platform and 
related Zope technologies. You can think of it as the 
rough equivalent of what Mozilla.org is to Mozilla.

Why has it taken so long? Because there is much more to 
"opening the development process" than simply doling out 
CVS access. Evolving a relatively large and complex 
piece of software like Zope is a non-trivial task, and 
doing it in a highly distributed environment is harder 
still. The dev.zope.org site will provide the background 
materials and tools to ensure that work on Zope is 
consistent in organization and execution. It will also 
help those new to Zope development to come up to speed 
and get involved quickly.

There is still plenty to do be done on the site, but it 
is done enough to start using it so I want to start 
learning by doing. If you have questions or comments on 
the dev site, please send them to me at [EMAIL PROTECTED] 
and CC the zope-dev list (which is where I expect traffic 
related to dev.zope.org should go in the near term).

I believe that this will work fine.  There has even been discussion
of doing this (having a python base class to reference the classes
you want your ZClass to have as bases) as a good technique for dealing
with the fact that you can't change the bases of a ZClass after it
is created using the management interface.

This means you are trying to delete a CatalogAware object that was
not entered into the catalog.  (Some have argued that this is a
but, some a feature).  To get around it, you can probably just
call the URL

/icds/Members/bob/index_html/index_object

and then do the delete.

You didn't specify the platform, so I'll suggest a nice, cost-effective
one:
Linux with IPVS (IP Virtual Server). www.linux-ha.com has more
information.

Uhm. Headers are headers, not content. As example, image files have
headers too but no
HTML inside. So you should set headers with RESPONSE.setHeader()

[Zope] Accessing the Application (or Control_Panel)

[Jeff K. Hoffman]

Hello,

I am working on a Python Product (subclass of ObjectManager) that creates
some instances of a few ZClasses inside itself when constructed.
Currently, I do this as follows:

  CONTROL_PANEL = None

  def manage_addMyClass(self, id, title='', REQUEST=None):
  global CONTROL_PANEL
  if CONTROL_PANEL is None:
  CONTROL_PANEL = self.Control_Panel

  self._setObject(id, MyClass(id, title))

  ...

  class MyClass(...):
  def __init__(self, id, title=''):
  self.id = id
  self.title = title

  ob = CONTROL_PANEL.Products.MyProduct.MyClass('myId')
  ob.id = 'myId'
  self._setObject('myId', ob)

which works fine, until I need to use CONTROL_PANEL from somewhere else
before manage_addMyClass is called (currently, I am trying to upgrade
existing instances in __setstate__). Inside __setstate__,
self.Control_Panel throws an exception, for understandable reasons.

So, I get the feeling I am going about this incorrectly. I grep'd the
source last night, looking for a getApplicationInstance() method, or
something similar, but found nothing. AFAICT, there is no easy way to get
ahold of the one true Application object without having a reference to an
object in the ZODB and calling getPhysicalRoot().

Did I miss something? Is there a better way to do what I am trying to do?

Easy dynamically generated pages (with or without RDB access)

I'm glad to see that 2.2.0 is finally released!  Now I have to ask a 
stupid, somewhat newbie, question.  I have an existing 2.1.6 Zope 
installation running under Windows 2000.  I have a handful of products 
installed.  I've read the article on upgrading to 2.2.0, but it doesn't 
explain the process of how to actually migrate a site from 2.1.6 to 
2.2.0.  What is the recommended way to move an existing 2.1.6 site to run 
under 2.2.0, particularly (for me) on a Win platform?

[Zope] Zope 2.2 final released!

[Brian Lloyd]

Hi all,


  Zope 2.2.0 final has been released - you can download it 
  from Zope.org:

  http://www.zope.org/Products/Zope/2.2.0/


  Many thanks go to all of those who have worked with the 
  alpha and beta releases and helped work through the more 
  than 110 (!) issues that have been closed since Zope 2.1.6 
  came out.

  The Zope 2.2 release includes:

- The new security policy implementation and object ownership 
  that addresses the server-side trojan issue:

  http://www.zope.org/Members/jim/ZopeSecurity/ServerSideTrojan

- The new online help system which provides context-sensitive 
  help for all Zope management screens and includes Zope API 
  documentation

- A built-in Zope tutorial to get new users started with Zope

- Basic internal support for mountable object databases

- A new "history" tab for selected objects that provides access
  to previous revisions through the web

- Better performance on many systems as a result of setting a 
  more appropriate value for the "check interval" of the Python 
  runtime

- Many, many bugfixes!


  For more information on what is new in Zope 2.2, see the 
  CHANGES.txt and HISTORY.txt files for the release:

- http://www.zope.org/Products/Zope/2.2.0/CHANGES.txt

- http://www.zope.org/Products/Zope/2.2.0/HISTORY.txt


  Note that there are important changes to the security model in 
  Zope 2.2 that both site maintainers and Zope product developers 
  need to be aware of. Site maintainers should read the document 
  "Upgrading to Zope 2.2.0" for important information on upgrading 
  their Zope sites:

- http://www.zope.org/Products/Zope/2.2.0/upgrading_to_220

  Product authors should read the "Product author's guide to 
  Zope 2.2+ security" to learn about the changes in 2.2 that 
  may affect their products:

impressive complex sophisticated graphs, but nothing to produce simple pie charts.  
Did I not look
hard enough?  Is there a better way?

The charts do not have to be live - the information changes at known times weekly, so 
I could run
external processes to create image files that are served using LocalFS, if necessary.

Thanks,

Richard

[Zope] suggestions for what to run in front of ZEO'ed zopes for failover?

[Roman Milner]

I'm wondering if anyone can suggest something good to run in front of
2 zopes talking to a zeo server - for failover and load balancing.  I
have been using a tool called 'balance' which works really well - but
for failover it only works if the socket to one of the zope servers
doesn't connect.

We occasionally have a situation where the socket will still answer
but the zope server hanges and never returns an answer.  So, I'm
looking for something with configurable timeouts on responses.  Does
any one know of anything like that?

Thanks,
^Roman

[Zope] GUF KeyError problem

[Mabe, Brad]

I am attempting to get GUF (using sql methods for authentication) working on
an HPUX box and am running into a bit of a snag.  Running ZOPE in debug mode
yields the following:

ERROR(200) GUF http://sidr:8080/test/acl_users/userRoles raised an exception
(( , ))

INFO(0) GUF Successful authentication for user test
(http://sidr:8080/test/acl_users)

ERROR(200) GUF http://sidr:8080/test/acl_users/userRoles raised an exception
(( , ))

INFO(0) GUF Failed authorization for user test
(http://sidr:8080/test/acl_users)

As usual I'm at a loss to what the problem is.  I have been successful in
getting GUF & sql methods  working on an NT box running zope, but never ran
into this problem.  Any help will be greatly appreciated.

Aaron - 

Are you passing AUTHENTICATED_USER as an argument to the 
query that is working (and not doing so on this one?) 
Remember that SQL methods don't automagically get the 
same namespace that DTML does - the only things it can 
use are attributes that are named in the arguments list
(this is to prevent names that are coincidentally the 
same in a REQUEST form or something from being inserted 
into queries).

One common way of doing what you want is to add REQUEST 
to the arguments list of the SQLMethod and use:



select * from data

Well, I've solved the problem by installing Zope from RPMs and having 
it connect to MySQL via TCP/IP instead of the default unix socket. So 
don't connect to 'localhost', connect to your machine's hostname.

But this still isn't solved. Where can I specify the path it 
shouldn't be looking for the ZMySQLDA stuff if it ain't in 
'/usr/share/zope'?

[Zope] ZPygres connection problem

[Oleg Broytmann]

Hello!

   I did an experiment (after having problems connecting Zope to Postgres)
- I stopped ZServer and restared Zope in PCGI-only mode.

   I opened connection successfully!

   I stopped PCGI and restarted ZServer. I again got BadRequest (cannot
connect to server).

   Anyone have an idea why Zope+ZServer cannot connect, while Zope-PCGI
can?

Your second question answers your first.

Zope's ZServer does indeed serve HTTP, but it only serves Zope objects.
Apache, on the other hand, allows you to serve much more, including PHP. You
can use Apache to integrate the two, there's a How-To on Zope.org that
explains how to do this, IIRC.

Basically, reasons for using Apache are:

- Using SSL (but there is an addon product for ZServer that covers this as
  well)

- Integration with other content, like static files and, in your case PHP.

- Virtual servers, competing for ip addresses or ports.

- Serving virtual servers out of Zope.

This is not a complete list, but these are the most important reasons.

On the other hand, using Apache introduces another level of complexity to your
setup, introducing a speed bump, a potential source of misconfiguration
problems, and another link in the chain that could break.

These methods have explicit settings to deny all access through the web or
through DTML methods. Use an External Method instead.

Well, while we're on the subject of AUTHENTICATED_USER.has_role, I've

[Zope] HTML Editors that recognize DTML

[Brad Moulton]

Hello All,

as  a newbie I was wondering if those zope developers who use Linux 
have come across any HTML editors that support DTML tags
I note that the Windows developers prefer Homesite.

I'd just like to know what the Linux community have tested and found
suitable
 I am currently using Webmaker but it doesn't support DTML tags or
syntax checking

I have also been asked to mention Dreamweaver I noticed that 
Dreamweaver  has a Coldfusion CFML plug-in
Is anyone interested in developing a similar plugin for DTML
I am only a novice python programmer but would be willing to help if anyone
feels it is worthwhile

Just some ideas as I am a python/Zope newbie but like what I have seen so
far.
i can only offer limited help at this stage but would be willing to help
wherever possible if a guru needs a disciple.

thanks to all those who have and are contributing to Zope. I cannot keep up
with all the Zope from the mailing list but am sure it will be very useful as I
progress along the path

Thanks again for the patch.  It is a much needed option (and rather a glaring omission 
from
the original code).  So far it is working flawlessly for me.

Is this necessary?  I actually use a variable for size (size=list_size) in the same 
,
and that part seems to work just fine.  Maybe mine is a special case, but I don't 
think so.

I for one am for it.  The lack of multiple and variable sort keys in version 2.14 were 
a major
hindrance to me.  I am sure that many tags could benefit from similar improvements.

Thanks again,

Aaron

Does it work, if you use the  construct
as follows:

Your email address has been used. 


Welcome ! You became a new
user. 


If not, are you sure you inserted usr_email into the "Arguments"-field
of your sql-Method?

   I always though why not to invite you here... And always answered to
myself - don't bother people who are too busy...

   Sure, this would be great.

That's odd, what catalog(s) do they show up in?

So you have the Squishdot object (Folder type thing) included in another
catalog?

Hmmm, this would all seem to imply that what Jens said about catalogs
not searching other catalogs that are included in their search items
isn't true...

cheers,

Chris
