For the record, I found this thread illuminating and entirely on-topic for 
this list. Thanks Carlos!

Re: [Zope] How can I get a listing of all objects in the Zope 2.62 ZODB?

ZODB is an hierarchical object database. So, yes, there is and no there isn't.
You can't just make a query and get all the data, the data is stored as objects.

On the other hand, getting tha data is dead easy, although you don't
make a query. You just write python. For example, to get all the
subobjects for a particular object, you write

subobjects = the_object.objectValues()

Tada!

Do that recursively, and you pretty much get all the objects you would
be interested in. Then you need to understand each object type, but
that's another thing. ;-)

Thanks!  I may give this a try.

FWIW, I've been toying with adding a @log decorator to my methods,
along the lines of the logger example at http://soiland.no/software/decorator
but i'm having some pain - will report back if i get it working.

Yes. But in real life you sometimes have an "oh s**t" moment
on production.  That isn't the case for me today, but I'm trying
to plan ahead :)

Found it at
http://www.wireshark.org/faq.html

Unlike tcpdump, it doesn't require pointing clients to a different
port (or running on the server and restarting the server on
a different port).

In modern ZODB versions (I think ZODB 3.6 and above),
there is an iterator which allows you to iterate over
all objects in the ZODB.

It main use case is to perform migrations between major updates.
But, if you know how to "list" your objects intelligently (this is much more
difficult than with Oracle where all objects have a strict schema),
you definitely can do this as well (but I doubt, you will be happy).

The ZODB level is *very* *very* low!
You do *NOT* want to work on this level when you have an alternative...

You may search the mailing list archive for threads about
synchronization between development and production environments.

The concrete approach depends on how your "tool" is implemented.
If it is file system based, then you can synchronize by replacing
the code with file system means (installing an archive).
If it is ZODB based, the "ZSyncer" may help you.
In some cases, you will need a hybrid approach.
And in the most complex cases, an intelligent installation
script will be necessary to make the necessary adaptions...

All form parameter are available from the REQUEST.form.
self.REQUEST gives you the REQUEST object inside an external method. 'form'
is basically a dict-like object so you can use the standard Python methods
for dicts for doing whatever you want.

[Zope] passing *args to external method

[Alan]

Hi List!

I've been trying without success to pass from a form in ZPT to an
external method an undefined list of parameters (*args).

An example:

def external_method(var_fix,*args):
  return 'Vals',var_fix,args
...
file _sub_html_:










returns typed value for var_fix and () for args. However, if I do:

def external_method(var_fix,arg1,arg2,*args):
 return "Vals",var_fix,arg1,arg2,args

it returns values of arg1 and arg2. But my problem is that the number
args cannot be fixed since such arguments depends on other page.

I hope one can understand it. And I'd appreciate very much any attention.
Many thanks in advance.

Cheers,
Alan

I found it very useful to log every xml-rpc call (call and return
value). For this we have patched ZPublisher/xmlrpc.py (and one line in
ZPublisher/HTTPRequest.py). See attachment (tested against 2.9.3).

The log entries look like that:

  Sep 10 06:58:40 bach-s10 xmlrpc id=-177841652, client=137.208.89.23,  \
   user=stupl, inst=bach-s10.wu-wien.ac.at:10082, path=/bach/stupl/RPC, \
   call=get_adreptl3(2002,)

   user=stupl, inst=bach-s10.wu-wien.ac.at:10082, time=88.27ms, out-ok, \
   ret=[('E', 19007, None, 7066351, 1, None), ('E', 19010, None, ...

OK, but when we're dealing with a production system, I can't raise 
random exceptions just to gather information.

This is a web service. It's not designed to interact with browsers.

Of course.

Thanks for the suggestions. 
I'll probably have to just bite the bullet and do more manual logging.
Unless somebody has any more ideas...

fwiw, I've also used tcpwatch (http://hathawaymix.org/Software/TCPWatch)
which is really great for inspecting the actual data on the wire,
but again that's not something i can do in production.

When debugging;
o Raise an exception from python scripts, you can include some info in it.
o Use FireFox and use the JavaScript Console to see the traceback returned.
o Don't forget to check /error_log in your Zope instance.

[Zope] POST sucks.

[Paul Winkler]

Been doing web services (XML-RPC) stuff lately.
What suggestions do people have for troubleshooting a zope-based
XML-RPC application?

Access and trace logs are totally useless, since even the method name is
hidden in the POST payload, so I feel like I'm flying blind; when a
client developer tells me he gets occasional hangs, I have no idea what
kind of request triggers the hang.

I may end up sprinkling my code with a lot more logging calls than I'm used
to.  Any other suggestions?

I understand that one can look at the Squishdot source
to find out. But it ought to be possible to query the
ZODB directly and observe all of the objects that are
in it.

See, I never manipulate dictionaries in TAL and forgot you had to do
it that way. I gave the wrong answer in my reply.

Just tal:define="null python:data['jname'] = jname" should do. No need
to make the dummy var global anyway.


But I get only error.


Traceback please. What is the error?


Is there a way of creating and increasing a dict inside Zope template page?


Why do you want to? Use a python script instead, or better still, use
a Zope3-style view.

You can perform assignment that way in ZPT. First it is bad style.
You really want to prepare your data inside a PythonScript, call
the script from a ZPT and re-use the data as returned from the script.
If you don't want follow that road, try this:

tal:define="dummy python: somedict.update({key:value})"

and I would like to do something like:

Is there a way of creating and increasing a dict inside Zope template page?

Many thanks in advance.

[Zope] sending updates with zope.

[Samuele Giovanni Tonon]

hi to all,
i have this problem which is related to zope.
we sell a tool inside zope that we install on a machine that stay
at our customer.

We need to find a easy but powerful way to update the tool if there
are bugs or new features .

after some research i've found zope synchronizer which is quite good
but it miss some function (i.e. checking the file instead of just
checking mtime ) and i would like if there are other products or solutions

Any hint is well appreciated.

thanks
Samuele
