Re: [Zope] something missing in my Oracle setup?

[Jens Vagelpohl]

hi justin,

it is your oracle install. i have had bad experiences with the fancy shmancy
8.1.x java installer myself.

oci.h is in a subdirectory of $ORACLE_HOME called 'rdbms'. i remember doing
the client setup did not give me the stuff i needed so i basically copied
everything it was missing from a second pretty much identical box with a
full server install. it would be easiest if you had a machine with a full
server install.

Re: [Zope] PowerMac 7500 with LinuxPPC and Zope?

[Jens Vagelpohl]

hi daniel,

zope should build and run just fine with that setup if you get the source
distribution and compile it yourself.

i am running zope on a pismo powerbook using Yellow Dog myself.

RE: [Zope] What is the best way to do this?

[Jens Vagelpohl]

alex,

IMHO when you try to do stuff using ZClasses and DTML and it starts
looking too complex to you then it is. DTML is made for presentation,
not for driving an application.

a very sound architectural approach, and one that scales very well as
your site and organzation grows, is a base of python-based zope products
with ZClasses that derive from them. all the logic happens in the python
product and all presentation is in the derived ZClasses. this will not
only speed up your code but it will also make it easy to control
presentation because that is stored in the ZODB and can be manipulated
through the web. the only drawback is that a change in the underlying
python product code requires you to restart zope.

if you're like me and can't stand messy and kludgy code you will
appreciate the extra effort spent on writing a real python zope product.

for starters look at "How to create a Boring Product" at
http://www.zope.org/Members/gtk/Boring/HowTo-Boring . this will explain
some of the structure that is needed for a python class to become a
"zope product". another guide is at
http://www.zope.org/Members/Zen/howto/ProductAPITutorial . for the
latest changes that need to be considered when writing a product for
zope 2.2 read brian's guide at
http://www.zope.org/Documentation/How-To/ProductAuthorUpdateGuide .

a good deal of knowledge can be gained from simply looking at the code
of products available in your zope install under
/lib/python/Products.

RE: [Zope] simple instructions for site search

[Jens Vagelpohl]

chris,

catalogs don't automatically search other catalogs they find. until this
is implemented you could create a separate catalog that only catalogs
other catalog instances (and your squishdot instance) and then you could
ask that main catalog to give you all its other catalogs and simply fire
off the search you want to do on each of them.

if your site is very simple and the location/number of catalogs doesn't
really change you could also hard-code them into a search page that asks
all of them directly.

RE: [Zope] PCGI still not functional

[Jens Vagelpohl]

bill,

i saw the same symptoms this weekend when i helped a good friend set up
a zope box to serve some of his domains from. his machine runs RH 6.1.
what did it for me was to copy Zope.cgi from apache's cgi-bin directory
back into the root of the affected zope install, he has two instances
running. after doing that the problems went away.

i double-checked the file to see if it points to the wrong places, but
everything in there seemed OK otherwise.

a simple workaround, but one that pretty much prevents any caching

RE: [Zope] Defining High Load in Heavily DB Driven site (was: [Zope] zope2.2.0 and what is high load)

[Jens Vagelpohl]

hi dario,

to clear up some possible misunderstandings and naming issues:

we have two different beasts here. one is the number of threads that
zope uses while it runs. this can be tweaked by invoking the start
script with an argument like "t " or by editing z2.py
and changing the default number of 4 threads. again, these are
application threads.

the database connections that were talked about are a different issue.
these refer to the number of connections zope creates to its underlying
ZODB object store. you can see them if you go to
/Control_Panel/manage_debug in Zope < 2.2.0 or by using the link
in the control panel in Zope > 2.2.0. the number of these connections is
set in /lib/python/ZODB/DB.py and the default is 7.

in general, when a thread attempts to do anything with zope it needs to
get hold of a ZODB connection so it can read or otherwise manipulate
objects in the ZODB. this is why the number of application threads
should be smaller than the number of ZODB connections. tweaking these
numbers is possible, but mileage may vary depending on your specific
site and usage.

Re: [Zope] re module & through the web security

[Jens Vagelpohl]

i for my part think it makes sense. not just from a security standpoint
(think of those sites that allow members who are not necessarily hand-picked
to write DTML or attempt to do so) but also from a knowledge level
standpoint. who wants their site crashed just because the new programmer
doesn't know how to use that re functionality correctly?

looking back at all the products and projects i have been involved in i did
not have to use the re module a single time.

as you know, you can still use the whole module in zope code that resides on
the filesystem, like in products or in external methods. i'd rather be
inconvenienced once every few months than basically invite denial of service
attacks.

Re: [Zope] Zope/PIL collision - what to do?

[Jens Vagelpohl]

try something like

import PIL

image = PIL.Image.open('foo.png')

that way you do not have two names "Image" colliding in the names Zope sees

Re: [Zope] Still More Problems On the Install...

i don't think python got to version 2.2.2 yet only zope did.

i suppose if you could send some of the "stuff" that printed to the screen,
especially the "stuff" around that error message, someone could help you.

and maybe what version of python you're really running.

ben,

as far as i know python 2.0 is not (yet) fully supported. if you look at
that famous INSTALL.txt again you will see this:


Important notes

   ZOPE 2.0 REQUIRES PYTHON 1.5.2!

   See CHANGES.txt for important notes on Zope 2.0.


so i suggest you try it with python 1.5.2.

Re: [Zope] première version de l'interface francisée de Zope

Hello,

(currently 2.2.4) to the following address:

http://zdp.zope.org/projects/zi18n/zzlocale/zzlocale_fr.tar.gz

* you should install the product zzlocale:

http://www.zope.org/Members/yemartin/zzLocale

* To create a repertory lib/python/locales under your root of Zope and
décompacter zzlocale_fr.tar.gz in this repertory.

You must then have: let us

lib/python/locales/fr/buttons
lib/python/locales/fr/tabs
lib/python/locales/fr/AccessControl/access.dtml
lib/python/locales/fr/AccessControl/addUser.dtml
[... ] 

* In Control_Panel (oops Paneau_de_controle) you have a mitre of management
of the language (fixes or according to the navigator)

It does not remain badly of shells, of awkwardnesses of drafting, and lack
of coherence. Do not hesitate has to make share of your remarks and
corrections. 

PS: Is Rémy for next the tar.gz, it possible to integrate the path
lib/python/locales/fr directly?

Re: [Zope] [python] converting int to string?

[Jens Vagelpohl]

in python you can do:

str(int)

and in zope you do it like

_.str(int)

"Learning Python" by o'reilly is a pretty good beginner's book for python. i
suggest you read it. it's well written and gives you the basics.

Re: [Zope] multiple unknown parameters -> ZSQL

[Jens Vagelpohl]

this could be done in python in either an external method or python
script/method. you can execute arbitrary SQL (which you would dynamically
generate in python) on a database connection using the "query" method that
is part of every database adapter.

you need to

- get a handle to your database connection by *calling* the database
connection you have in your ZODB, like "db_conn = self.mydbconnection()"

- once you have constructed the string carrying the SQL for one update
statement you can pass it as argumant to the query method on the database
connection, like "result = db_conn.query(sql_string)"

looking at that page you put up you will have to create a SQL string for
every student shown on the page and pick the correct variables from REQUEST
for the SQL update statement.

Re: [Zope] REQUEST object - obtaining variables from

[Jens Vagelpohl]

here's how you could display the form variables on the receiving object:




  : 




REQUEST.form will contain all the fields from the form and
REQUEST.form.items() will give you access to all key-value pairs that you
can then access with sequence-key and sequence-item in the loop.

Re: [Zope] basic &dtml syntax question

jason,

this is called 'entity notation'. the semicolon is a standard part of it.
another example of an item in entity notation would be to replace "<" with
< or the often abused blank space  

this entity notation is a general HTML thing, it's not zope-specific.

Amen. Actually, instead of maintaining them in the core the current

"negative" caching means that there is a separate cache to cache failed 
user lookups for a while and return a failure immediately instead of 
re-trying the user lookup doing a (possibly expensive) user search in 
the underlying backend.It's a little bit like Squids negative_ttl, 
which is used to specify a duration for caching error responses. The 
negative cache allows the backend to "recover" and/or prevents backend

[Zope] CMF 1.5.1beta2 Released

[Jens Vagelpohl]

Zope Corporation is pleased to announce the release of version 
1.5.1beta2 of the Zope Content Management Framework (CMF). This release 
is intended for testing purposes only;  we do not recommend deploying 
it to production servers.  The final release of version 1.5.1 is 
expected on the weekend of April 24, 2005.

What is the CMF?
The Zope Content Management Framework provides a set of
services and content objects useful for building highly
dynamic, content-oriented portal sites.  As packaged, the
CMF generates a site much like the Zope.org site.  The CMF is
intended to be easily customizable, in terms of both the
types of content used and the policies and services it
provides.

I guess I should've prefaced my question by saying that I know on-error
normally ends propagation of the exception.  I guess I was wondering if
there was some way to manually add the exception to an error_log 
object so
that i can come back later to analyze that logfile, while still 
presenting
a non-confusing error screen to my users.
There is a method named "raising" on the SiteErrorLog object but I 
don't see a way to call it from a PageTemplate itself because it seems 
to need the actual exception object as its argument.

This is, to be frank, a bad setup for a ZEO server. ZEO servers are

moving away from RAID-5 to something simpler like RAID-1.


Now, did anyone try to let repozo write the backups onto a nfs share on
another machine? Would that reduce the hit?
Yes. At least the backup write activity would hit some other disk.

Besides that, how often do you guys run your backups? In fact, I never 
needed

to
have as recent data as possible, of course.
There is no golden rule. It all depends on your specific setup and how 
fast your data grows, and of course how recent you want to be if you 
need to restore from backup. I haven't had a setup where backup needs 
were so urgent that an hourly backup was done, nightly has been good 
enough so far. With weekly packing.

To put it in a very simple way, you should not tweak the threads 
setting unless you really know what you are doing. If your goal is 
performance the usual way of going about that is to run ZEO and add ZEO 
clients as needed.

You're bumping into the very simple fact that there are two items 
interacting badly: Threads and the connections in the Zope database 
connection pool. A thread, under normal circumstances, can only do work 
if it has a connection to work with, and wwill only release the 
connection when the request is finished. There are 7 connections in the 
pool by default.

Re: [Zope] high loads, more threads, spinning wheels

[Jens Vagelpohl]

Can this be taken to mean that:
- the practical maximum number of threads to run your single (non-ZEO)
zope instance is {number of zodb connections in pool} else you risk
deadlock
No, there should be more connections than threads, just as in the 
original configuration.


if yes, would upping the number of ZODB connections effectively raise
the ceiling - e.g. 12 ZODB connections -> 12 threads should perform
properly ?   Is increasing the number of ZODB cx's possible, let alone
advisable?  (why the default of 7 - not 6 or 8?)
More concretely, is there any good way to increase the request-handling
capacity of a standalone instance, beyond the limits imposed by the
defaults, without deploying ZEO?
Trying to squeeze a single instance that way is fraught with problems, 
and not just the experimentation needed to come up with sane values for 
threads, connections, and then connection cache sized to avoid memory 
contention. A single Zope process also means you are running one Python 
process with one global interpreter lock. It's just a bad situation to 
base a production site on. Use ZEO and set up additional clients as 
needed, anything else is hackish and error-prone.

Ah, OK thanks.
Is it for the collector that, aside from messing up the ZMI a bit, the

I suppose it could be argued that custom_zodb.py should simply not be

There is nothing you set up to make Zope "use" a user folder. It will

Umh, no. First of all, all user folders have that ID. If not, they  
are not user folders. Secondly, the ID is not used to hook into the

And the containing folder has __allow_groups__ attribute set to

folder.

In fact you can call your user folder anything, as long as this

It is perfectly OK to have several user folders. The "closest one"

The fact that authentications falls through to the root user folder

- Make a backup copy of your old ZODB

- if you don't have a LDAPUserFolder in the Zope root you can skip  
that and log in as a Manager user from the root user folder

- Delete every single LDAPUserFolder instance you have
- Stop Zope
- Copy the Data.fs into your Zope 2.8-based sandbox
- If you had a LDAPUserFolder at the root, make sure you're set up

[Zope] CMF 1.5.2beta released

[Jens Vagelpohl]

Zope Corporation is pleased to announce the release of version  
1.5.2beta of the Zope Content Management Framework (CMF). This  
release is intended for testing purposes only;  we do not recommend  
deploying it to production servers.  The final release of version  
1.5.2 is expected mid-July 2005.


What is the CMF?

The Zope Content Management Framework provides a set of
services and content objects useful for building highly
dynamic, content-oriented portal sites.  As packaged, the
CMF generates a site much like the Zope.org site.  The CMF is
intended to be easily customizable, in terms of both the
types of content used and the policies and services it
provides.

Since that is probably specific Plone functionality you might be  
better off asking on the Plone lists.

If there is a set of distinguishable IPs/hosts, then use a tool that  
was *made* for that purpose such as a firewalling/filtering tool  
(IPTables, IPChains, fw, etc) and not Zope.

Umh, that's incorrect. zopectl debug has nothing to do with debug  
breakpoints or pdb. And you can run it right alongside your running

the root object is bound to "app", nothing more and nothing less.

One correction: If you use ZEO you can run it alongside the running  
instance. Otherwise, since it would want exclusive access to the  
database, you could not. One of the reasons why ZEO is recommended  
even in single server setups.

2. "session" - a Session Auth Helper active for  Extraction, Update

3. "users"   - a ZODB User Manager with a single user "test"
4. "roles"   - a ZODB Role Manager with the "test" user assigned to

Then accessing a "Manager" protected method inside the folder  
brings up the
login form from the Cookie Auth Helper, but submitting that form  
does nothing

(it returns the empty form to me).



Add "Extraction" to the cookie object. Only the cookie object would  
know how to extract credentials coming back from the cookie object's  
challenge. Makes sense, doesn't it?


I have described such a setup before either here or on the PAS list  
itself, take a look at the archives. The very first challenge and  
extraction is done by the cookie auth helper, and the credentials are  
then stored by the session auth helper which is doing all extractions  
after that.

It's the other way around. Permission first, then the method name.

There is no problem with this, if I use the method on the current

method on another property.


The output of VerboseSecurity is:

*Error Type: Unauthorized*
*Error Value: Your user account does not have the required

['Anonymous', 'Authenticated', 'User'].*


It appears that the currently authenticated used has the 'View'  
permission (required to use getProperty) on itself, but not for  
other users. I'm not sure how to change this.


I'm assuming that the "other" user is not wrapped. How are you  
getting that other user object?

No, it's the other way around. You want the wrapper. getUserbyId  
returns unwrapped users.


If you use CMF or something based on CMF you could use the membership

you'll have to do the wrapping yourself:


user = acl_users.getUserById(user_id).__of__(acl_users)

[Zope] [ATTN]: CMF and related packages moved to svn.zope.org

[Jens Vagelpohl]

Hi everyone,

I just finished migrating the CMF and related projects from  
cvs.zope.org to svn.zope.org, from CVS to Subversion. All tags and  
branches have moved, unlike Zope itself there won't be some  
development using CVS and some using Subversion. These are the packages:


- CMF
- CMF_Hotfixes
- CMF_Extras

They packages became new toplevel projects at svn.zope.org, as can be  
seen here:


  http://svn.zope.org/

Pending final agreement on the CMF list (or an overriding word from  
the CMF Pope himself) svn.zope.org will now be the canonical location  
for CMF sources. They are accessed just like Zope 2.8 and Zope trunk  
as described here:


  http://www.zope.org/DevHome/Subversion/ZopeSVNFAQ

The only difference is, of course, the last element in the path.  
Eveerything else works as described in the document linked above. The  
packages are at...


  /repos/main/[CMF|CMF_Extras|CMF_Hotfixes]

***To all CMF developers***:

Please change your sandboxes and convert them to SVN. If you see any  
problem please make it known on the CMF list as soon as possible. No  
data is lost on cvs.zope.org, so if there are show-stoppers we can  
always switch back to using CVS. Please **do not** commit into  
cvs.zope.org or svn.zope.org until we have a "yay" or "nay" on which  
repository we go forward with.


***Next steps***:

If we have agreement on using svn.zope.org a couple cleanup tasks  
need to be done, such as...


- "Close off" or "freeze" the CMF projects on cvs.zope.org to either  
disallow checkins or bring up big fat warnings if someone tries to.  
Input and ideas on this are welcome, if it was up to me I would use  
the "commitinfo" file in the CVSROOT to completely prevent updates as  
the first step.


- Change any references to cvs.zope.org in the CMF code to their  
svn.zope.org equivalents


- Change any references to cvs.zope.org on the project web pages,  
mostly http://www.zope.org/Products/CMF, to point to the svn.zope.org  
equivalent


- Change any download instructions that use CVS to instructions for SVN

How? Give me an example!


Take a look at the unit tests which exercise the FSZSQL code, there  
is a sample one that is part of the fake skins directory used by the  
CMFCore unit tests:


http://svn.zope.org/CMF/trunk/CMFCore/tests/fake_skins/fake_skin/ 
testsql.zsql?rev=37165&view=markup



I can't give this information because it doesn't raise exceptions.  
It works (not raise errors), but not properly.


I never saw an example of ZSQL Methods running from file system in  
CMF, can you give me this?


My intention is just contribute, however, solving a real problem I  
have.


You're still giving no clue about what exactly it is that works "not  
properly".

Re: [Zope] Getting a methods parent (in a product)

Hi!

How can I get a Product instance's _actual_ parent when one of its
methods is called? (In other ways: how can I find out, from an
instance, where that instance is located without falling prey to
acquisition in Zope 2?)


from Acquisition import aq_inner, aq_parent

parent = aq_parent(aq_inner(self))

This will return the true container the instance is set in, not just  
the acquisition parent.

Re: [Zope] FSZSQLMethod.py refactory

[Jens Vagelpohl]

I only wait that someone test my reimplementation of parser and  
says me it's really insignificant.


I would like at least not to have that trash (...) in  
the body of the method.


As far as the CMF goes, IMHO it doesn't make much sense to put code  
into the repository just because one person doesn't like the way  
arguments are handed to these ZSQL methods. They work perfectly as is.


I fail to see how several lines of double-hash-escaped lines is any  
less "trash" than the comment-tagged version that is there right now.

Re: [Zope] Different IPs, one zope instance

Hello everyone,

We a have a server with 5 differents IPs.

How would it be possible to specify one IP (only one out of 5) to the
Zope server?


Yes. See the "servers" directive in zope.conf, which documents all  
this very well.

What's so bad about
parent = self.aq_parent


Two things:

- simply using aq_parent does not guarantee giving you the real  
containment parent. Depending on the path used to access the object  
it could be something different from the true containment parent.  
That's the power of acquisition...


- direct attribute access like that makes me feel dirty. I prefer the  
true object-oriented style where you use methods to get at stuff.

Re: [Zope] zoperun vs start and ssh

This may be a stupid question, but, after searching the archives to
find out how to keep Zope running after starting and then
disconnecting from a remote ssh session, nothing works.

First, the Zope manual and all the archives messages talk about using
./start. That doesn't work for me unless I am just in the wrong
directory. I am running ./zoperun from /bin.


The "start" script was used in Zope versions up to 2.6.x, replaced by  
"zopectl" for safely starting and stopping Zope in the 2.7-series and  
up. Apart from that, packages that are put together by other people  
or by Linux distribution maintainers may have their own scripts.


I have no idea what "zoperun" is, I'm assuming you mean "runzope.py",  
which is part of 2.7.x and up? If not then this smells like some non- 
standard package, you should contact its maintainer.
