Subject: [Zope] Best Practice for including Javascript in Zope Applications
Message-ID: <001001c84cd5$47aacca0$460aa8c0@home.msh>

Hello,

 

I'm new to developing for zope, and I have a quick question regarding some
best practices when using Javascript in zope applications.

 

I would like to use Ext JS (http://www.extjs.com/ ) in an application that I
am writing.  It is a fairly extensive library, so I didn't really want to
copy/paste every single file into a dtml method.  I looked all over the
place for some discussion on this subject, but only found things relating to
plone (which apparently has a javascript registry); however, I wish to stay
away from plone for this particular application. 

 

What should I do to use these libraries?  Is there a canned solution for
this sort of thing?

 

Thank you much!

 

-Matt

The simplest route:

  - Create a "File" object in the ZMI for each separate javascript
    library (e.g., 'extlibrary.js').

  - Upload the static content of the library file to that object.

  - Include a link to the JS library in your master page template,
    e.g.::

     <script type="text/javascript" src="/extlibrary.js" />

Larger JS frameworks like Dojo tend to be split across several files and 
directories. The fun starts when such frameworks load/reload stuff
using relative URLs. A co-worker using Dojo intensively had to invest
some time in order to integrate such a JS monster properly. As far as I 
remember Extjs also uses multiple files (but not as much as Dojo does)..so 
please check in advance.

Another point: consider using CMF and putting your library files into a
directory system view on the filesystem. This makes your life much easier.

Or just upload via WEBDAV.
One of the biggest advantages of Zope is the isolation from physical
file system.

Hello,

Thanks to everyone for your help.  I thought about Tres's solution and
quickly discovered that I would be doing a *lot* of clicking/typing if I
wanted to upload all of the files necessary to make the ExtJS framework
available.   I'll look into the WebDAV idea; I didn't think of that until
you mentioned it.

However, I came up with another possible solution that may be generally
useful after some (a lot actually) of coaxing.  I threw this together in the
time between my new year's festivities :) : it's incredibly sloppy at the
moment, but before I worried about cleaning it up, I wanted to get some
feedback from you guys about it (pardon the annoying formatting problems):

def package_home(gdict):
    """Returns the location of the file that calls the function.  You 
    must pass it globals() as the argument for it to work right.  
    
    :Parameters:
        gdict : dict
            A dictionary containing all of the global definitions for the
            module.  This is accessible via the python built-in function
globals()
            
    :return: The fully qualified path for the directory in which the calling
        module is residing

    and returns it.

This class is working like a charm as it stands (I have
js=FileSystemResource("js","Javascript Repository") in my published object),
but it is terribly sloppily implemented for the time being, especially in
regard to binary files (doing for line... instead of going over chunks) and
to caching/memory issues (there is no caching except for the intermediate
objects and everything is loaded into memory first [big files = unusable]).
And someone could just pass ../'s to the path to get anywhere on the file
system they wanted, I suppose.  All of these could easily be fixed of
course, but I wanted feedback before I put more than 30 minutes into the
prospect :)

Thanks for all your help!

You can ftp the files to a "static" directory on the file system and  
use LocalFS to access them.

Subject: [Zope] Defining a Variable
Message-ID: <4dc0cfea0801021044q491f8709g1cf20c8698518be8@mail.gmail.com>

Hi;
I have this in a page template:

<html>
<body>
<table>
 <tr>
  <td tal:define="num python:here.scripts.getQuote">
   <span metal:use-macro="here/en-us/quotes/?num/macros/quote" /><br />
   <div align="center">
    <span class="text">
     <a href="quotes.pt" target="_top"><b>The quotes</b></a>
    </span>
   </div>
  </td>
 </tr>
</table>
</body>
<html>

Now, I thought that was the correct way to call the variable "num" (that is,
with the question mark: "?num"). Apparently, I'm mistaken. I've even tried
defining it this way:

  <td tal:define="num python:str(11)">
to make sure that num was properly assigned. What am I missing? Also, if I
have a dir called "scripts" in which "getQuote" exists, and "scirpts" is in
the path, shouldn't that notation work okay?
TIA,
Victor

Not sure if using the '?' will working within a TALES expression. It will
at least work as the last item with an expression. However it will fail in 
general if 'num' is an integer.

I am writing an application that uses extjs as the front end and zope
on the back and they work together really well.
I am using a webserver to server the extjs library and everything else
comes out of zope.  So far I have had no trouble with relative links
or files broken up in different locations. It may be because I have
fully committed to having an extjs front end. I typically serve a page
out of zope, it calls the extjs library as well as custom JavaScript

Have fun because you have just come across a wonderful
combination...extjs and zope!

Yep!  I have had very good luck with it so far; my little hack that I posted
works like a (klutzy) charm and ExtJS is great with zope.  The ExtJS folks
are very well organized, and the library is quite powerful.  It's working
great.  However, my application doesn't have quite the segregation that
yours does; ExtJS and zope (DTML in particular) are much more intermingled,
and can't be easily separated.  This application is actually a frontend for
a Java library that controls instruments at CERN (a research lab I work
for), and I love the solution that it has presented.  It works like a charm.
(in case you're curious, it makes use of a wonderful python library I ran
across called JPype (http://jpype.sourceforge.net) to execute the Java code)

I am going to be accessing Zope through apache with the VHM, but there are
multiple reasons why I don't want to serve the js through apache.  This same
principle is the reason that I don't want to upload things through FTP or
WebDAV.  I'm making a product, and I would like to keep it atomic, i.e., I
want the only install procedure to be "copy product folder to
instance/Products".  Uploading via WebDAV, or hosting the javascript using
separate software, defeats that purpose.  

The solution that Tom proposed (LocalFS) seems to be what I want, but the
problem is that I think it is way too out of date; it crashed my zope server
(2.10.5) when I installed it.  It says nothing can be found after I add an
instance through the ZMI, and this is after I fixed a deprecated import (
from OFS.content_types import find_binary -> from zope.app.content_types
import find binary).  I had to completely remove the product to get my Zope
instance to work again.  

I'm getting the feeling that there isn't really a (recent) canned solution
for accessing file system content, which is... strange at best, considering
all the power that zope has at its disposal.  You would think that accessing
the file system would be present just because it is so simple to do.  I'm
not complaining, as I'm *very* happy with zope, I'm just surprised :).  I
realize that zope's principle is to store everything in the database, but
this is unacceptable for content such as video files, right?  I mean the
ZODB file would be absolutely humongous (and slow?  I don't know for sure
how it's implemented).

If there isn't already a working solution, I would be happy to come up with
one; I could just hack out the parts of LocalFS that work, add a few
features, and repackage it into a new product.  It's not difficult to do (my
little trivial solution already would work fine if I did a non-dumb
implementation of the file-serving logic), and as much as I would like to
use it for other projects, it would be worth my time.  For example, I want
to make a little video/music server as a personal project unrelated to my
current one, and I really don't want to store things in the ZODB if I can
help it... 1 video = +1 gig ZODB? :S

I don't know much about zope obviously, so if I get some vehement objections
to this route, I'll pick another :)

Thanks!

Applications

I am writing an application that uses extjs as the front end and zope
on the back and they work together really well.
I am using a webserver to server the extjs library and everything else
comes out of zope.  So far I have had no trouble with relative links
or files broken up in different locations. It may be because I have
fully committed to having an extjs front end. I typically serve a page
out of zope, it calls the extjs library as well as custom JavaScript
files. The web2.0 style page then makes multiple xhr calls back to
zope to load smaller html and json fragments. Works like a charm and
has the additional benefit of letting me cache the majority of the
front end in the webserver and in the users browser.

Subject: [Zope] looking for an easier way
Message-ID: <20080102231012.GF10970@asu.edu>

I'm writing an exteranl method to store data into a sql data base. In my
first attempts to do this I just had an external method dump whatever
zope gave it to a text file, then looked. I came up with the following
to split up the data the zope handed the external method and store it
an sql. This works. However, I'm thinking there must be an easier way
to capture what zope hands and external method.

Here's what I'm using now:

def ddmapper(data):
    ''' maps dictionary keys and vals handed from zope to
    dictionary keys and vals which are attribute names of the table use to store the data
    puts a pickle of all data into a zo -- zopeobject
    nonce is a uniquifier
    '''
    now = DT.now()
    pbuf = sio.StringIO()
    pickle.dump(data, pbuf)
    nonce = '%s:%s:%s:%s' % (now.year, now.month, now.day, now.second)
    attribs = dict(fname=data['first-name'],
                   lname=data['last-name'],
                   email=data['email-address'],
                   studentid=data['student-id-number'],
                   accomodations=data['will-special-assistance-be-required'],
                   describe=data['describe-special-accomodations-needed'],
                   degree=data['degree'][0],
                   number=data['number-attending'],
                   key=nonce,
                   zo=pbuf.getvalue()
                   )
    del(pbuf)
    del(now)
    return attribs


There must be an easier way to 'know' what zope is giving me and grab
the correct dictionary that has the form data in it. anyone have any
pointers?

A couple of ideas:

(i) use Zope marshalling to store all fields from an html form into a record 
(dictionary)
(ii) get all form fields via:  REQUEST.form.keys()

Hi!
I plan to create a product I call Zope Smart Manager that consist in a view
similar to freemind for Zope
You could see a picture of my prototype here:
http://blogs.sistes.net/Garito/images/ArbolYanged.png

The idea is create a series of monkey patches to all the products we are
interested to see as tree nodes and a series of javascript (prototype +
scriptaculous) for the "client side"

I plan this ZSM view will be my main work view with edition and creation

For that I need some help about how to create the simplest monkey patch and
the javascript objects

I have no experience with monkey patching zope nor javascript object but
I'll learn all the necessary skills if no one wants to help

Can you help me at any point?

Thanks!

this the new standard in 2.11?

No, Zope 2.11 uses a Zope 3-based approach.

While I can see visual differences, how does this tree behave
differently than the one which the ZMI shows?

I don't know why you think you need to moneky-patch anything:  you
should be able to create such a view using the standard API supplied by
pretty much every existing Zope object.  The ZMI tree code is here:

  $ZOPE_HOME/lib/python/TreeDisplay/TreeTag.py

This is just a tree rotated counter-clockwise.

The only issue I see here is the problem to render the graph from left to 
right instead from top to bottom. There are several graph-drawing tools
available (best to start with Graphviz) that generate images or 
HTML/Imagemaps.

Matt,
  Please keep us updated on your strategy for serving extjs. I am also
considering making my application a product for distribution but I was
thinking along the lines of an install script for macs that would set
up the apache webserver. I also like your approach.

BTW, I haven't done it, but couldn't you just store an object in zodb
that has a pointer to  your video on the filesystem and access the
video via a zope product? But maybe that is what LocalFS does, I
haven't checked.

see ya in the extjs forum. Just do a search for "zope"

 Well, it shows (or will show) not only collection objects, it shows simple

As Andreas already has pointed out, you probably need "getQuote()"
rather than "getQuote" (as the name suggests, it is a method not a
value).

>   <span metal:use-macro="here/en-us/quotes/?num/macros/quote" /><br />

"?var" in a path expression means: replace "?var" by the value of "var".

Therefore, if "num" contains the right value, the above should work.

Hello,

Ok, I came up with a solution that I like; today I spent a little while
making it so I don't have to load things into memory before they are served.
Now it works quite nicely for serving out js/css/gui pics.  I won't post
what I did right now, as I haven't really cleaned it up and I'm ashamed of
how it looks at the moment,  but I'll post the usage of it to see if anyone
would like to use it after I clean it up:

...
from util import FileSystemResource #it's just in a utility module for my
current project at the moment
...

MyZopeObject(Implicit,Item,Whatever):

	#"js" and "css" are paths that are considered relative to my package
directory (not the cwd for zope).  It can be absolute too, if desired.
	js = FileSystemResource("js","Javascript Repository") 
	css = FileSystemResource("css","CSS Repository")

Now, say that there is ext-all.js in a directory called
"/path/to/zope/Products/MyProduct/js/".  You could then link to the java
script file by going to http://domain.com:8080/myZopeObject/js/ext-all.js.
In particular, in dtml, I have a standard_html_header that looks something
like this:

==standard_html_header.dtml==

<html>
<head>

<!--Set the title-->
<title><dtml-var title></title>

<dtml-comment><script src="&dtml-absolute_url;/js/navbar.js"/><!--GUTS
navbar--></dtml-comment>


<link rel="stylesheet" type="text/css"
href="&dtml-absolute_url;/js/resources/css/ext-all.css">

<!--Source in local_js unless the variable isn't defined-->
<dtml-try >
  	<dtml-in expr="local_js">
	<script src="&dtml-absolute_url;/js/&dtml-sequence-item;"/>
  	</dtml-in>
<dtml-except><!--Do nothing-->
</dtml-try>

</head>

<!--Start the body-->
<body class="&dtml-id;-body" id="&dtml-id;-body">

<!--Set basic pre-nav header-->
<dtml-unless NO_HEADER>
	<h1 id="main-title">This is a title.</h1>
</dtml-unless>

==!End standard_html_header.dtml==

Then in MyZopeObject, I wrap up my DTML in a method like so:

..<other class stuff>...

_main = DTMLFile("dtml/main",globals())
def main(self):
	main_js=["ext-all.js","main.js"]

	return _main(self.REQUEST,local_js = main_js)


I did the whole local_js thing so I could control what JS got dropped into
what pages without having to write a different header for each one.  I will
probably also do the same thing for the css just in case I want
page-specific css files.

This is what I'm doing at the moment, and it's working great.  If this would
be useful to someone else, I'll give it more than an hour and a half of
thought, rewrite it more intelligently, and make it available.  Otherwise,
thanks to everyone for their comments!

-Matt

Matt,
  Please keep us updated on your strategy for serving extjs. I am also
considering making my application a product for distribution but I was
thinking along the lines of an install script for macs that would set
up the apache webserver. I also like your approach.

BTW, I haven't done it, but couldn't you just store an object in zodb
that has a pointer to  your video on the filesystem and access the
video via a zope product? But maybe that is what LocalFS does, I
haven't checked.

see ya in the extjs forum. Just do a search for "zope"

Thank you both. However, it still doesn't work :( I have replaced "getQuote"
with "getQuote()", but to no avail. Other ideas?
*Error Type: RuntimeError
Error Value: external method could not be called because it is None*

first, I don't think you can assign a variable name to a python
function using tal and then have tal 'call' the function.

second, I think what you do want is the get the results of calling
getQuote into the variable called 'num', and then use those results
elsewhere.

I think tal variables can all be first class python objects. If not,
any standard python object works -- in other words, a list, tupple,
string, dictionary, etc. If you have your own object, it will need to
have an iterator method defined for it -- but then, I wouldn't know
how to make the new class known to zope.

acquisition will find many things. What does getQuote return though?

You see here how important it is to always provide full problem
description. Usually, beside "Error Type" and "Error Value" the
traceback, too, is very important.

The error information above tells you that your problem is
not the "?num" but your "External Method".

Unfortunately, the information is not very precise.
You need the following background information:

    When an "External Method" cannot be loaded (e.g. because
    its source is not found), then it is represented as "None".

You get more information, when you visit the "External Method"
in the ZMI and press "edit".

That was too wierd. I deleted the External Varible, then re-added it, and
all worked well! Now, I just built this new server and transfered over the
Data.fs files. Maybe that was the problem??
Thanks,
Victor

Basically you look at the clients ip address (from the REQUEST object)
and perform any action you need (redirections, conditions within scripts,
templates)...but no idea what the sense of this usecase is. If you have 
different audiences, setup sites with different content or something 
similar. In addition: using Zope behind proxy will lead in request coming
from the IP address of your reverse proxy. Additional 
configuration/programming is necessary to get hold of the original IP.

Thanks for the reply.

The use case is that my client wants to block a range of IP addresses
from being able to view their site. So I need to access the
originating IP address and filter appropriately.

I've written a few custom zope products before, but I've not done
anything that really modifies zope's behaviour on every request - just
on requests for the specific objects I'm publishing. So I'm familiar
with the request object, but I don't know how to intercept *every*
request. Are there any global request life-cycle hooks? If you can
point me to those that would be a great help.

Cheers,
David

swap out "theipaddress" with the actual IP.

<dtml-if "REMOTE_ADDR == 'theipaddress'">
true
<dtml-elif "HTTP_X_FORWARDED_FOR == 'theipaddress'">
true
<dtml-else>
false
</dtml-if>

You have a firewall for this purpose or you use apache rewrite rules for 
performing URL rewriting.

If you just need to redirect traffic from an IP range, and not do  
anything fancy, it may be better to do it in Apache rather than Zope.

Our host uses nginx, not apache. We can still do this w/ nginx
configuration, but it means maintaining a configuration file rather
than application code (which in my experience is more
flexible/maintainable). Right now I'm just exploring options, so I'd
still like to know how I can do this with Zope.

BTW - I'm using ZPT, not DTML. I'm guessing I can do this with a
simple script that I include on every page, yes? That could work, but
seems a bit error prone - that's why I'm looking for some sort of
request hook. But maybe that's my best option within Zope. Thoughts?

This issue is a configuration and not an application issue. So it basically
does not belong into Zope.

That's a pretty narrow view in my opinion. We nearly all already display 
different content to different classes of user, I fail to see how grouping 
those users by IP address is really any different.

Narrow or not..it does not belong into directly in Zope in my opinion. If 
you were using Plone for example as CMS, you could create your PAS plugin 
providing dedicated roles for different IP ranges (or something similar) 
and control the visibility of content through the standard Zope security by 
granting View permission (and others) to the related roles.

I guess if you want to do this easily inside zope, then a script is the
way to go. Somebody already posted a dtml solution; however, I think it
is better you put it in a python script that will be called from your
standard_header file, which can be either a dtml method or a page
template.

A request hook will require you to patch zope, write a monkey patch, or
some kind of UserFolder based on ip addresses, which means to directly
modify zope's code or create an external product. The invested time on
doing this isn't worth, when you can do it easier and in less time, with
either a script or by modifying your proxy's configuration.

I think it would be better to let your proxy do this. This isn't really
hard with nginx:

http://wiki.codemongers.com/NginxHttpAccessModule

Anyway, if you don't have access to the maschine hosting your zope, then
you should try the script solution.

Are you saying you want an access rule?

Well, I guess that would be much easier than the script solution I
mentioned before. You can put your access rule, which is also a script,
on the folder you want to restrict. You have to be careful with this
rules since you can block your access to the site; however, this
can be easily undone.

My code works fine in normal running zope but not when run as a testcase 
(I'm not using bin/zopectl test if that matters) I get the following error.
I feel guilty since I've got this line in my code:
transaction.get().commit()  (Expense.py#4458)

I remember having come across this error before but can't remember what 
the solution was.

Well, this error is self-speaking :-)

The standard solution for figuring out the related property/attr keeping 
the instancemethod is: pdb. Look at the object or its __dict__ and check 
what is
inside or think about your code where you might be assigning a method 
somewhere.

Damn it! Not the answer I was hoping for. I was hoping for something 
simpler and more obvious :)

What object do you suggest I inspect in the debugger then? I don't know 
how the ZODB figures out what it needs to save.

And this solution is possible in Zope, too (after "PluggableAuthService")
has been installed).

And of course, this solution is in Zope (and not the web server
or the firewall).

When "SiteAccess AccessRules" are used for security critical demands
then one has to keep in mind that they can be disabled via special
segments in the url.

In such a case, I would remove the code that makes this possible.

That's trivial start your debugger in ZODB.serialize._dump() and check
the 'state' parameter (should be a dict). Using pprint.pprint(state) will
make the output less painful...just check the output for something with
instancemethod or something similar smelly.

Message-ID: <c11816150801071310o421f4eefjdce3d404ce00258e@mail.gmail.com>

Hi,

I have a need to generate an md5 hash for an XML fragment generated by
TTW Zope code.

I thought I could do this with "allow_module" - I have a
pseudo-product with an __init_,py that contains: -

# Global module assertions for Python scripts
from Products.PythonScripts.Utility import allow_module
allow_module("md5")

In my TTW python script, I have: -

import md5

hash=md5.new()
hash=hash.update('test')

...but when I execute the script I get: -

Error Type: Unauthorized
Error Value: The container has no security assertions. Access to
'update' of (md5.md5 object at 0xb98ab00) denied.

I'm basing this on: -

http://www.zope.org/Documentation/Books/ZDG/current/Security.stx

...specifically the section entitled " Utility Functions For Allowing
Import of Modules By Through The Web Code".

I thought I understood this, and have used it with other Python
modules, but based on what is happening with the md5 module, I
obvioulsy don't!

Can someone clue me in, or point me towards more recent or explicit
documentation, please?

FAQ!

allow_module() does not work with all and everything.
Use an external method or a browser view instead or move your code into 
your zope product code (if you have one).

Yes, there have been a good few questions about this - I spent a lot
of time googling yesterday, and found a couple of threads where the
questioner seems to have given up at this point.

The problem seems to be that it works "some of the time" - I have
another case where it works (pywintypes, FWIW).

In this case, how could I know that allow_module() will not work with
md5? IOW, how could I tell the difference between a module not being a
candidate for allow_module() and an error in my own code?

I understand that an external method or a product are my other
choices, but I'm really uncomfortable about not understanding how I
can tell when I can and when I cannot use allow_module() - at the
moment, this feels horribly like "trial and error" coding!

Enough people have struggled with this that I'd like to understand it
well enough to add something to the wiki for the next person who has
the problem...

You might also want to look at http://betabug.ch/wiki/HoneyPotBL
which is a module that accesses the projecthoneypot.org HTTP blacklist
database. The actual code to block access is not in this module (as I
believe it's application specific), but anyway it might be interesting.

Yes, I saw that.

I've been in this situation a couple of times before, and have not
pursued the "allow_modules()" option because it was simple enough to
create an external method. However, this "seemed" like a nice simple
case where allow_modules() "should" work, so I wanted to get to the
bottom of it and understand my previous problems.

>From what you say, the most useful comment I could add to the wiki
would be to quote your original response that "allow_module() does not
work with all and everything" and add my own conclusion that if
allow_module() does not work in a given case it is not worth spending
much troubleshooting time on.

I'm happy to accept your advice that allow_modules() simply won't work
in all cases - but that's the advice I wish I'd found in the wiki 24
hours ago...

Liberty League International, Signs Of A Real Internet Home Business

The world of internet home business is often clouded by people trying to
scam opportunity seekers. This can make for a very disheartening and
difficult process of finding a real home business opportunity.

Part of the problem is that there are so many choices in home business
opportunities. The internet has made home business something almost anyone
can, no matter their budget. This also has created the perfect breeding
ground for those who love to offer big promises but fail to deliver.

In order to find a real internet home business opportunity a person has to
understand how to spot a real opportunity from a scam. This may sometimes be
tricky, but it can be done when a person has the right knowledge.

One of the key differences between a real home business opportunity and a
scam is that with a real opportunity the company is willing to tell
everything up front. They make it clear what the business is and how money
is made. They never try to hide anything or keep details vague.

Another big sign of a real opportunity is that there will be plenty of
people who are willing to back up the company. These people may be customers
or even other business owners. People who have worked or who are working for
a company are the best source of information. They will be able to give the
real scoop about if the opportunity is real or a scam.

Also look for a genuine, proven system of making money through the business.
If there is not a clear way that money will be made then it is not likely to
be a real home business opportunity.

Finding a real home business opportunity is something that can be despite
the many scams that seem to about there. There are plenty of real home
business opportunities that can make a big profit and be successful. It is
just all about weeding the real one from the scams.

Five Point Capital, Searching for the Right Keywords through Staff Leasing
Companies



A growing number of websites compete to be among the top ten listings in the
search results. This position gives them a higher possibility of getting
more customers compared with a lower rank. Web marketers use several tools
to achieve high rankings, probably one of the most important although others
don?t realize, is keyword research.

There are many tactics for optimizing a site to have high search rankings.
But since most visits to a site start with a search engine click, optimizing
a site for the right keywords is really critical. This is why keyword
research is so important, right?

It is really important that you will be able to target all relevant keyword
phrases to be able to be among the top rank websites. You just can?t afford
to guess the keywords often searched by people, or else you?ll see your
businesses slowly toppling down. Searching for the right keywords for your
websites doesn?t simply take a day or two. It would sometimes take a week or
more.

If this is so, how can busy people maintain or increase the ranks of their
websites. Yeah, maybe it can be done, but how sure that it is done
systematically and professionally? Hiring a new employee to do this can also
be costly for a company especially if it is just starting. Some resort to
webmaster staffing?

Getting someone from a webmaster staffing company to do professional keyword
research and other services can do no harm to your business; it is to your
advantage, in fact. The company wouldn?t have to provide office space for
the staff as they will be working in their own place but still under your
directions. Plus, you?re free from hiring and training costs. Staffs from
webmaster staffing companies like Agents of Value are already well-trained
and were able to pass extensive screening process to be able to provide
world-class services.

Opting to hire from a webmaster staffing company can lessen your overhead
expenses like overtime. This companies also charge lower for their services
compared to others so you will be able to save in your labor cost. Most
outsourcing offices are found in places with lower cost of living.

Keyword research may sound so easy but finding the right ones takes time and
effort. Only people who have the time, knowledge and training can do this
efficiently. If you want to get your sites on the top list, a webmaster
staffing company is the best choice for you to look for someone who?ll work
it for your business!

outsourcing company that offers programming, online marketing and graphic

Wendy Stevens Nashville Tennesee, So You Want To Start A Home Business


Wendy Stevens Franklin Tennesee



So you want to start a home business, and don't know where to begin. Like
any other business, research the company your interested in. Find out all
you can about their business practices, their creditability, what they offer
and exactly what you will be doing in this home business.

When researching a business, keep in mind these 3 red flags:

1. Introduction Material Costs Money.

This information should be free. It introduces the company, tells what they
do, what they offer, and how to sign up.

2. Promise of Getting Rich Quickly in Less Than 10 hours a Week.

Though it is possible, it isn't probable. It takes time to build a business
and clientele. You should expect to work more than 10 hours a week, and it
take awhile to build any income.

3. Limited Time Offers.

A company is making promises (especially of quick wealth), but you only have
a certain amount of time to enroll; I'd take a step back and reevaluate the
situation. Generally, these are scams.

There are reputable companies that use some of these techniques, just make
sure to do your research. My best advices is look for a business that
interests you, do the research to enable you to make the best decision
possible, have realistic expectations, and enjoy your endeavors.

Message-ID: <18307.57840.43009.80436@gargle.gargle.HOWL>

Today, I detected (and fixed) a nasty bug in my "ManagabelIndex".

The bug affects indexes with "TermType=='DateInteger'".
When for such an index a "DateTime" value is converted to a "DateInteger",
the input is rounded up to a "Date" rather than rounded down.
Because this is applied uniformly to all "DateTime" values,
the bug becomes visible only when true "Date" values and "DateTime"
values are both involved.


The bug is fixed in version 1.7.3 which can be found at

  <http://www.dieter.handshake.de/pyprojects/zope#ManagableIndex>

After "ManagableIndex" is updated, all affected indexes needs
to be reindexed (as otherwise the update makes things worse:
the indexed values have used rounding up while the queries
use rounding down).

Apparently, you have an "instancemethod" in your test setup
where you do not have one in the normal Zope.

An alternative explanation could be that in your normal
Zope additional pickle registrations are performed.
If you would use, e.g., my "CompiledExecutable" product,
then the import of this product would register "code" and "instancemethod"
instances as picklable. A test setup may not import "CompiledExecutables"
and its pickle registrations would be missing.


A side note: Usually, it is a very bad idea to perform a full
"commit" in a test. Such "commit"s are incompatible with
techniques that share (for efficiency reasons) part of the
test setup among several tests. "ZopeTestCase", e.g., makes
use of such techniques.

An "allow_module" allows import of the module and all its content.

It does not in general allow to use the objects inside the module.
For example, to use class instances for classes defined in the module,
the class must provide its own security declarations which control
in what way the instances can be used.

In your case, the module contains special types.
You need an "allow_type" for each of these types to be able to
use them.

Hi,

I am unable to log-in into the my zope server. This just happened because I have not changed my log-in info.

Afterwards I also tried to create emergency user and still unable to login.

I used the plone3_buildout to build the zope and plone. And what I noticed was that i have 2 zpasswd.py files in my installation.

one here: C:\optilux\bin\parts\zope2\utilities
and another one here : 
C:\>cd optilux\bin\parts\zope2\lib\python\zope2\startup\misc

Any help will be highly appreciated.

Thanks.

You can always create a new account using

zopectl adduser username password

and login with this account.

Hi!
I have subscribed to this list for some years
In this time I make some questions to this list that sounds weird for
a part of you

Perhaps my english is poor, perhaps my ideas are weird but doesn't matter

If the question is that my english is poor perhaps some code will be
more clear that my words, I don't know

Now it's time to code

I would like to introduce you Zope Smart Manager, perhaps it speaks
better than me

Please feel free to check this silly idea at: http://code.google.com/p/zsm/
Note that this is a very, very early stage of the project but I would
like to show you the way I see your beautifull and amazing work

Please feel free to contribute as deep as you like but give a chance
to it (perhaps you could understand my point of view better and we
could understand us better too)

I will appreciate your visions and your opinions

I love Zope's simplicity but I aspire to do go deeper in this way: simplicity

Sorry for this days of misunderstud and thanks a lot for your help
(even when I was think you could help me more ;) )

Hi, all!
If you have download the ZSM product you could see I put on it a zexp
file with prototype and some other js file and a css file plus images

This was only a prototype solution to bring you the chance to see how
my ideas are but I think this is not a definitive solution

Now my question:

Which is the best zope way to serve this kind of files trying to avoid
any other product dependence?

Thanks a lot!

Hi!
Thanks Martijn and Matt for your ideas!
@Matt: can you explain with more detail the question about
REQUEST.response.write()? If the written content is as long as a file like
prototype is not a very heavy solution?

The contents of the zexp file are only js files and images (static content)
and I'm using Zope2

What about the functionality of the freemind view? What do you think about?

Thanks!

Hi!
I'm try to implement the edition part of ZSM and I begin with the rename
objects functionality
I create a InPlaceEditor object to rename every branch but when I submit the
form the rename command works ok but the response is the manage_main (or
similar) and the tree disappear

Is there a way to make manage_renameObjects returns the changed values?
If not I need to write another monkey_patched function, isn't it?

Thanks!

Many "manage_*" functions/methods have been designed not only to be
used as simple functions but as also part of the ZMI.
When used as ZMI functions, they must (eventually) return some HTML.
They either do this by itself returning the HTML or by redirecting
to an HTML page.

These functions often distinquish between the "normal function use"
and the "ZMI use" by looking whether "REQUEST" is passed in.
If used as a ZMI functionality, the ZPublisher will pass in "REQUEST"
automatically.

>Is there a way to make manage_renameObjects returns the changed values?
>If not I need to write another monkey_patched function, isn't it?

If you need to use these functions via the "ZPublisher", 
then it is best to make a little wrapper that is "ZPublisher" called
instead and then calls the function without passing "REQUEST".

Ok
Then I put another function into the monkey patch to rename the objects
Did you try to install the product? I'm specially interested in the opinions
of big helpers like you

Thank you very much!

In the context of Five / Zope3, the static content items are
"resources".  One strategy would be to create a Zope2 product with those
files in a subdirectory, e.g.::

  $ mkdir Products/garito
  $ cd Products/garito
  $ echo "# ZSM product" > __init__.py
  $ mkdir static
  $ cat > static/garito.css
  body {
    background: #CCCCFF;
  }
  ^D

And then register that directory as a "resource directory" via ZCML::

  $ cat > configure.zcml
  <configure xmlns:browser="http://namespaces.zope.org/browser">
    <browser:resourceDirectory
        name="garito"
        directory="static"
        />
  </configure>
  ^D

Now, when you start Zope2, you can pull in your static resources via
special URLs, like http://localhost:8080/++resource++garito/garito.css::

  $ cd ../..
  $ bin/zopectl start
  . daemon process started, pid=25240
  $ telnet localhost 8080
  Trying 127.0.0.1...
  Connected to localhost.
  Escape character is '^]'.
  GET /++resource++garito/garito.css HTTP/1.0

  HTTP/1.0 200 OK
  Server: Zope/(unreleased version, python 2.4.4, linux2) ZServer/1.1
  Date: Fri, 11 Jan 2008 18:53:11 GMT
  Content-Length: 32
  Last-Modified: Fri, 11 Jan 2008 18:44:47 GMT
  Connection: close

  Content-Type: text/css; charset=iso-8859-15

  body {
    background: #CCCCFF;
  }
  Connection closed by foreign host.

In that product, you could also register a template / browser view which
includes your resources, e.g::

  $ cd Products/garito
  $ cat > garito.pt
  <html>
  <head>
   <link rel="stylesheet" type="text/css"
         href="/++resource++garito/garito.css"/>
  </head>
  <body>
  <h1> Garito's view </h1>
  </body>
  </html>
  ^D
  $ cat > configure.zcml
  <configure xmlns:browser="http://namespaces.zope.org/browser">
    <browser:page
      for="*"
      name="garito.html"
      template="garito.pt"
      permission="zope2.View"
      />
    <browser:resourceDirectory
      name="garito"
      directory="static"
      />
  </configure>
  ^D
  $ cd ../..
  $ bin/zopectl restart
  $ telnet localhost 8080
  Trying 127.0.0.1...
  Connected to localhost.
  Escape character is '^]'.
  GET /garito.html HTTP/1.0

  HTTP/1.0 200 OK
  Server: Zope/(unreleased version, python 2.4.4, linux2) ZServer/1.1
  Date: Fri, 11 Jan 2008 19:02:05 GMT
  Content-Length: 151
  Content-Type: text/html; charset=iso-8859-15
  Connection: close

  <html>
  <head>
   <link rel="stylesheet" type="text/css"
         href="/++resource++garito/garito.css" />
  </head>
  <body>
  <h1> Garito's view </h1>
  </body>
  </html>
  Connection closed by foreign host.

Which pulls in your static resources.

In the context of Five / Zope3, the static content items are
"resources".  One strategy would be to create a Zope2 product with those
files in a subdirectory, e.g.::

  $ mkdir Products/garito
  $ cd Products/garito
  $ echo "# ZSM product" > __init__.py
  $ mkdir static
  $ cat > static/garito.css
  body {
    background: #CCCCFF;
  }
  ^D

And then register that directory as a "resource directory" via ZCML::

  $ cat > configure.zcml
  <configure xmlns:browser="http://namespaces.zope.org/browser">
    <browser:resourceDirectory
        name="garito"
        directory="static"
        />
  </configure>
  ^D

Now, when you start Zope2, you can pull in your static resources via
special URLs, like http://localhost:8080/++resource++garito/garito.css::

  $ cd ../..
  $ bin/zopectl start
  . daemon process started, pid=25240
  $ telnet localhost 8080
  Trying 127.0.0.1...
  Connected to localhost.
  Escape character is '^]'.
  GET /++resource++garito/garito.css HTTP/1.0

  HTTP/1.0 200 OK
  Server: Zope/(unreleased version, python 2.4.4, linux2) ZServer/1.1

  body {
    background: #CCCCFF;
  }
  Connection closed by foreign host.

In that product, you could also register a template / browser view which
includes your resources, e.g::

  $ cd Products/garito
  $ cat > garito.pt
  <html>
  <head>
   <link rel="stylesheet" type="text/css"
         href="/++resource++garito/garito.css"/>
  </head>
  <body>
  <h1> Garito's view </h1>
  </body>
  </html>
  ^D
  $ cat > configure.zcml
  <configure xmlns:browser="http://namespaces.zope.org/browser">
    <browser:page
      for="*"
      name="garito.html"
      template="garito.pt"
      permission="zope2.View"
      />
    <browser:resourceDirectory
      name="garito"
      directory="static"
      />
  </configure>
  ^D
  $ cd ../..
  $ bin/zopectl restart
  $ telnet localhost 8080
  Trying 127.0.0.1...
  Connected to localhost.
  Escape character is '^]'.
  GET /garito.html HTTP/1.0

  HTTP/1.0 200 OK

  </head>
  <body>

Which pulls in your static resources.

Thanks Andreas and Dieter,

The explanation was quite simple, I set an attribute on an object that
was a method like this::

class TestBase(ZopeTestCase.ZopeTestCase):

    def dummy_redirect(self, *a, **kw):
        self.has_redirected = a[0]
        if kw:
            print "*** Redirecting to %r + (%s)" % (a[0], kw)
        else:
            print "*** Redirecting to %r" % a[0]

    def afterSetUp(self):
        self._setupDBConnection()
        dispatcher = self.folder.manage_addProduct['MExpenses']
        dispatcher.manage_addHomepage('mexpenses')
        self.mexpenses = self.folder['mexpenses']
        self.mexpenses.http_redirect = self.dummy_redirect # NOTICE!!

        request = self.app.REQUEST
        sdm = self.app.session_data_manager
        request.set('SESSION', sdm.getSessionData())

        self.has_redirected = False


The reason for the dummy redirector is boring. The reason for the
transaction.get().commit() is to not cancel everything when a
ConflicrError happens during a very long-lasting file upload.

Again, thanks.

PS. Andreas, I did use your set_trace() tip on the ZODB code. Isn't
Python great!

I try only products the description of which clearly indicates that
I need them.

You decided to let your code speak -- but this has no chance with me :-)

Subject: [Zope] NamedTemplate.__call__ not returning anything
Message-ID: <fme72q$vjk$1@ger.gmane.org>

Hi,

I have some code where I try to get a named template and render it and
if it fails I render a default template instead.  But this fails,
presumably because the __call__ method of NamedTemplate does not
return anything.  From zope/formlib/namedtemplate.py (Zope 2.10):

class NamedTemplate(object):

    def __init__(self, name):
        self.__name__ = name

    def __get__(self, instance, type=None):
        if instance is None:
            return self
        return component.getAdapter(instance, INamedTemplate, self.__name__)

    def __call__(self, instance, *args, **kw):
        self.__get__(instance)(*args, **kw)

I seems strange to me that __call__ does not actually return
anything.  Is it just me?

Now, I have some other code where NamedTemplate is working just fine,
so there is probably nothing wrong with this __call__ method.  So can
anybody tell me what is wrong with my following code then?

class Renderer(base.Renderer):
    default_template = ViewPageTemplateFile('vocabularyportlet.pt')

    def render(self):
        """Render a named template or the default template.
        """
        template = NamedTemplate("test.vocabulary")
        try:
            output = template(self)
        except ComponentLookupError:
            output = None
        # Even if the component lookup works, output can be None.
        if output is None:
            output = self.default_template()
        return output

The line "output = template(self)" fails with a ComponentLookupError
unless a named template with the name test.vocabulary exists.  But
when that template is found, output is still None.

In case you want to see the entire code, this is in a Plone portlet
that I am developing:
http://svn.plone.org/svn/collective/collective.portlet.vocabulary/trunk/collective/portlet/vocabulary 

And actually, the tests that I added pass when I change the
NamedTemplate.__call__ method to return the value that it just got.

So should that method be changed or is there a different way to do this?

Thanks,

I am building a plone3 site using buildout, but I've noticed that the

have a different interpreter.  So much so that the scripts in ZODBTools

It returns only if you use "return" (otherwise, it returns "None").

Thus, try "return self.__get__(....)".

I doubt that your message here will have a lot of effect.

You may file a bug report ("https://bugs.launchpad.net/zope/"),
but I am not sure that that will have much effect, either.
The problem may be too minor that anyone wants to fix it.

I know. :) I think you misunderstood me there.  This class is from
core Zope (zope.formlib.namedtemplate).  So to refrase my question:
why does this call method not do "return self.__get(....)"?  Looks
like a bug to me, but this line has been there since 2005 and named
templates do seem to work fine, so I am confused.

Actually, when I remove that __call__ method from namedtemplate.py,
the zope.formlib tests still pass (and in fact all 5868 tests from
bin/test.py pass).  Tested on the Zope 2.10 branch.

So I would say: either the call method should be fixed by making it
return the value it has just calculated, or it should be removed.


When I remove the call method, my own code sill throws an error, a
different one now:

AttributeError: NamedTemplateImplementation instance has no __call__ method

For a minute I thought I could work around that by directly using the
only line from the above class that I really need:

template = getAdapter(self, INamedTemplate, 'myname')

But that still throws the same AttributeError.

I must be doing something strange...

Subject: [Zope] Zope ZMI Templates
Message-ID: <14734109.post@talk.nabble.com>


I'm currently developing some customized ZMI pages and I was hoping someone
could give me some insight into what the best way would be to do this.

I see that Zope 2 uses dtml methods to build the standard ZMI pages but as
far as I know (Zope 3 wise) I should rather be using Zope Page Templates to
build the pages.

I would also like the product to gracefully move on to Zope 3 in future, so
that should be taken into consideration as well.

Are there perhaps some existsing templates for ZMI that can also be used
with Zope 3?

I would strongly advice against building on top of the ZMI. It's dated 
and as you say, in DTML. It's also too geeky to be acceptable by any 
client of mine.
Personally I'd build something standalone that you have ultimate control 
over. You can still use things like manage_renameObjects() in your own 
mnagement interface; which you'd be able to replace once you move to zope 3.

You could choose to use a 'zmi_master' template which looked like so::

 <metal:x metal:define-macro="master">
 <tal:x tal:replace="structure context/manage_page_header" />
 <tal:x tal:replace="structure context/manage_tabs" />
 <div metal:define-slot="main">
   Non-boilerplate goes here.
 </div>
 <tal:x tal:replace="structure context/manage_page_footer" />
 </metal:x>

If you registered that template as a view in your product's
'configure.zcml', e.g.:

  <browser:page
     for="*"
     name="zmi_master"
     template="zmi_master.pt"
     />

you can then use it in your own ZMI templates, e.g.:

  <html metal:use-macro="context/@@zmi_master/macros/master">
  <body>
  <div metal:fill-slot="main">
   <h1> Test ZMI Macro </h1>
  </div>
  </body>
  </html>

I have attached a tarball of a simple Zope2 product which does this.
After installation, you should be able to visit
http://localhost:8080/zmi_test to see the results.

Hi again, Tres!
Can you point as where we can find this kind of help? Are there some
reference manual or similar? (I'm using Zope2) Perhaps on Five manual?

Thanks a lot!

I'm afraid I don't know the docs very well:  I tend to use the source
when memory fails me. ;)  Honestly, I typed those examples in off the
top of my head, and then created the product to test them:  except for a
single typo, it Just Worked (TM).

Jurian,
  While the ZMI is a bit geeky for the average user, it works quite
well inside an iframe.
iframes are used by many ajax/web2 (whatever you want to call it)
libraries. So in my application (for example) I currently make ajax
calls to load specific zmi pages inside tabs of a window layout.

I agree with Peter that you are better off building your own interface
(if you are going to expose the manage_* methods) but I personally
hope the zmi stays around for a while!

Subject: [Zope] lambda's in external methods
Message-ID: <20080116032144.GK19750@asu.edu>

In the zope 2.7 book it mentions that an optimization technique for
external methods is to compile regular expressions in global scope to
the module. The re's will then be compiled at zope load time.

I am wondering if the same holds for lambdas. I created some simple
filters using lambdas. I defined them in the functions where I use
them. Is there any advantage to defining them globally to the module?

Are there any gottcha's with globally scope objects?

IFRames. You should avoid those. With ajax or similar its easy to skip
such stuff and just replace any named container tag.

I don't think that this is very specific to Zope but a general 
recommendation for any Python application. Since compiling regexes can be 
expensive you want to compile then once. Defining them on the module level 
is the common solution.

I don't see any relationship between lambda expressions and regex since 
there is no compilation involved when dealing with lambda expressions - 
except the byte code compiliation however this takes place when importing a 
module - not at runtime.

This is a general programming question - no necessarily tied to Python. A 
general answer might be: define only those things globally that must be 
globally (aka void global namespace polution). Usually define some 
constants or something similar globally in order to avoid moving those 
parameters around..but it depends on the individual usecase.

Iframes are still a valid choice in case asynchronous won't work e.g. when 
you need to load resources from servers != your origin server. Due the 
security model of asynchronous requests, a browser will only load stuff 
from the origin server. Iframes are a way to work around this limitation - 
ugly as you said, but sometimes a good workaround.

"lambda"s are (as well as any static Python code) compiled at
load time -- independent of their position.

When you move the "lambda" to the top level, then the "lambda" object, too,
is build at load time. Otherwise, the object is build when the
function containing the "lambda" reaches the lambda.

However, construction this object from the predefined pieces is not
very expensive.

The other important difference between ajax loaded pages and iframes
is that when you click on a link within an iframe page, the returned
page is loaded into the same iframe.
If I am not being clear, please check out this png file.
<a href="http://medicinebrain.com/iframe.png">
http://medicinebrain.com/iframe.png
</a>
In this png I did a search for DML Docs within a tab panel and the
search results are loaded into the same tab.

BTW, I would like to simplify the zmi even more for my users. I want
to hide various tabs (eg. security, find, etc) and I want to restrict
the number of products they are shown in the drop down box for adding
to a folder.
However, I still want to offer complete zmi functionality to the
overall administrator.
I can probably hide the security tabs using css (the overall admin
won't load the css sheet) but how can I control the products displayed
to a user in the folder view of the zmi?

Thanks,
Tim

Subject: [Zope] Plone middle aligns all colums
Message-ID: <9A6213D6CEDE5147A5FA6559410C363D02A4D9C5@Mail1.ktd.com>

I have a weird problem with our Plone 2.5.3 test site after a new
designer took over. Plone now middle aligns the content column and the
portlets in the slot on the center line, instead of on top. 

 

 

                                              --------------------

 

---------------------------

|     Left-slots                |

|                                        |        center

|                                        |

---------------------------

 

                                             ---------------------

 

We can sort of fix this by manually adding vertical-align: top; in the
css. But my designer claims that he caused this by "changing a setting
in Plone or the ZMI" and doesn't remember which one. 

 

Since it's not on the production site, it's not a life and death
situation, but any suggestions what might cause this are gratefully
accepted. Google and the Plone site search yielded pretty much nothing. 

 

Thanks,

Lars Hohmuth

You can either sub-class if you want to explicitely specify the products
you want an objectmanagerish class to add - this would also nicely solve
all your ZMI "problems" since you could just skin your new pages as you
want. Or for the easy way have a look at the Security Tab, specifically
at the "Add FooBar..." stuff there.

Not only ugly but also a very security threat. Been there, seen a lot
important sites fell on their noses when it comes to CSS* and friends.
Better find another solution in such cases and allow users to disable
support for iframes for better security.

I bet you're running a non-standard user folder, and for some reason  
the user folder instance is broken. If you can't find why it is broken  
and the broken user folder is at the root of your Zope instance then  
fixing it would involve work in the debugger to delete the old one and  
create a new standard user folder.

If you've introduced tables into the overall layout tds will not align  
the content to the top by default. You'd need to add "td {vertical- 
align: top}" to your css. I doubt the problem has to do with a setting  
in Plone or Zope. It would be easier to trouble shoot this if there  
were a link to the page in question.

You really should be writing a custom UI for this rather than hacking  
the ZMI. It will probably take less time, be much more manageable,  
flexible and secure.

Tom,
  Thanks but I think I am almost done. I have replaced the old <style>
calls with id="Find" id="Properties" etc. by access the sequence. Then
I added css code at the top of that same file (I think it is
manage_tabs.dtml, I'm not on that computer right now). So now I can
format the tabs anyway I want. There is also a little bit of
javascript that checks window.parent.location and applies changes to
the tabs if the user hasn't logged into the base directory.(only
available to the admin).

My thinking is that the zmi is battle tested. I'd rather use something
that many people have already been using. Plus, from my perspective,
it looks to me like the zmi just needs a little updating.
Incorporating style sheets, etc. and it can have a new life.

zope 3 people:  zope zmi, dtml are fast and really useful, please
don't toss these valuable tools!

There's nothing wrong with the ZMI. You're just try to hack into some  
kind of cms rather than just build one. Hiding a link with css is  
nasty hack and major security issue. While it may seem like what  
you're doing is an easy path to a quick cms, you're really just  
setting yourself up for a management nightmare. I'd recommend reading  
through (all of) this:

Hi,

What is the best way to delete all the objects inside an object

Tom,
  My modification of the css has nothing to do with security. It is to
simplify the UI for general users. And I use the zmi not because it is
easy but because it is proven.

If you have any specific examples of the management nightmare created
by using zmi as a cms I would very much appreciate hearing about them.
I think all websites are a management nightmare! (but it doesn't stop
facebook from becoming a platform, eh?)
:)

Thanks,
Tim

are there any compile time optimizations for python that would also

Not really. Why do you ask? What is slow? What appears as slow?

I'm putting zope/plone on a virtual machine and I would like to
optimize for memory consumption if possible. I don't know how rapidly
the hosting service I'm using could add ram to the vm.

Memory optimization is tricky. Especially ZODB cache tuning. But there is 
nothing at a compilation that would help you. Perhaps one thing: there is a 
switch that cares about the internal unicode representation (UCS2 vs UCS4).
UCS2 might be the better choice since it will use only 2 byte per unicode 
character instead of 4.

The only one I know of for Python-compilation time:

 - Ensure that Python is compiled to use UCS2, rather than UCS4, for
   unicode (UCS2 is the default, but some "system" pythons use UCS4).

Runtime:

 - Run python with '-O' on the command-line helps (it turns of some
   'if __debug__' logging).

 - If you don't allow untrusted users to create templates or scripts
   on your site, set 'skip-ownership-checking yes' in your zope.conf.

 - Ensure that debugging and profiling are disabled in zope.conf.

 - Set your log levels as high as you can (at least INFO for the
   event log).

 - Tune the ZODB connection cache size (more objects, more memory,
   but faster).

 - Tune the ZEO disk cache size (the warning sign is seen lots of
   "ZEO cache flip" entries in the event log).

IIRC, Products go in each zope instance.  The zeo instance gets the ZODB.

Correct.

And there is nothing wrong with using the same Products directory for
all zope instances (well, you would call them zeo clients really).

So: make the Products directory of the second instance a symbolic link
to the first one.  Or edit the zope.conf file of the second one and
point to the Products dir of the first one in the products directive.

Normally the ZEO server doesn't need to have access to the products,
which are "application code".  The only exception is for products which
define classes having application-level conflict resolution:  in such
cases, the ZEO server must be able to import the product (or else the
conflict resolution code is not consulted).

Can you explain this some more?

1. Do we increase the cache size when we see these ZEO cache flips?
2. What is a "good" rate for these cache flips?

offtopic, but persistent zeo caches - especially with larger cache sizes - 
require a lot of time for performing cache validation/invalidation at start 
time (sometimes minutes..).

Yes  In general, keep increasing it until they are no longer "noticeable".

I don't have a firm sense, but no oftener than every hour, say:  when
the cache flips, you lose half the working set (the "oldest" half).

Modern ZEO versions no longer use a flipping client-cache. The cache
is now maintained in a single disk file (and no longer two, with flipping
between them).

As an additional note:

  Zope uses Python import magic to make packages available
  in "INSTANCE_HOME/Products" as additional products in
  the "Products" package.

  If some of these products need application specific conflict
  resolution, the ZEO server needs to activate this
  import magic -- by importing Zope's "App.FindHomes".

As an additional hint to save memory:

  Ensure that the ZODB cache size is tight for the
  "temporary" database (which contains the session data).
  The default size is usually far too large.

  This advice is especially important when you keep large
  amounts of data in your session objects.

An patch to runzeo that allows INSTANCE_HOME Products to be put on the  
path (but does not require Zope's App.FindHomes is here):

https://bugs.launchpad.net/zope2/+bug/143770

Using this patch, you can create a Products directory in your ZEO's  
instance home and put products in there to service conflict resolution  
while still keeping SOFTWARE_HOME products on the path.  Importing  
App.FindHomes might be a better way to do this.

So would this also apply to older zopes? Like 2.7.5?? Exactly where is

Perhaps I'm wrong but I suspect that a Zope I'm running is dying because 
of running out of threads. They probably die when being designated to 
open an external relational database connection or something dodgy.

What are my options for monitoring and debugging what zope's threads are 
doing?
Is there a simple tool to just get a simple readout of how many threads 
are busy?

One simple option is the ZMI Control_Panel Debug screen. Go to / 
Control_Panel/DebugInfo/manage_main on your instance and scroll to the  
bottom. It shows current connections to the Zope server from the  
outside, and how long the connection has been around. You will always  
at least see one entry, which is the request to fetch that debug  
screen. If you have connections beyond a few seconds of age they may  
be stuck.

May be you can try by using just 1 thread and then debug it to see how 
it dies.

This is very unlikely. It may no longer respond when all its threads
are working -- but it will not die for this reason.

Zope uses a worker thread pool (of size 4, by default),
allocated quite early.
It does not create further threads. It is therefore very unlikely
that it hits a thread limit.

By dying I don't mean crashing and stopping but instead staying up and
running but not responding to anything. Like a coma.

I'm just not certain if it's this. It seems highly related to MS SQL
connections but I could be wrong. The strange thing is, restarting the
MS SQL server might be (we're not certain) a solution to get Zope
responding again.

My theory was that the threads get too attached to a network service
that doesn't time out or raise an error.

Sadly I can't reproduce it but the next time it happens I'll look at
both DeadlockDebugger and the Control_Panel Debug info if there are
any clues there.

This symptom, especially when these "hanging" threads cause no load at  
all on the system, certainly point to connections to outside systems  
that do not respond for some reason. I have seen this issue with Zope  
instances that make HTTP calls to other systems, or even with a  
hanging LDAP server which accepted connections from Zope but never  
returned. Any software that makes outgoing network connections from  
Zope is a potential suspect.

GDB can help you determine where the hanging condition originates.

You have absolutelly true!

I was the same problems in past. I was make up to 150 threads in some rare 
cases, but 50..100 in general if I use MSSQL. It was with Zope 2.5.1, with 
modern zope, see attachment about pool_size.

Now I use 80 threads and 60 pool_size and my Zope+MSSQL is fine. MSSQL hits 
in day peaks 100% CPU load (about hour, two) , but it is not my business. 
But my business is functional zope webs which eats a lot of RAM due caching 
policy - about 5..10 times more than before... So you have been pointed and 
warned ;-)

Best Regards, JL.

Message-ID: <98450e7d0801221624n3d4b1580ya08165125be69064@mail.gmail.com>

How do I upgrade Five (http://codespeak.net/z3/five/) from v1.3.8 to
v1.4.4 in Zope v2.9.7?

The Plone product I wish to install (Reflecto v1.2 -
http://plone.org/products/reflecto) apparentl. requires v1.4.1+.

Frustratingly, the installation page
(http://codespeak.net/z3/five/INSTALL.html) and INSTALL.txt file for
Five do not actually explain how to install it.

Many thanks.

By downloading the Five tarball and replacing Products/Five with it.

Just download and put it in your Products directory (where you put
Reflecto too) and Zope will prefer that version over the one shipped
with it.

Just drop the 'Five' directory into your instance's 'Products' 
directory, just like you would install any other product (e.g. Reflecto).

Plone, btw, should already ship with Five 1.4.x.

Use the "DeadlockDebugger" to find out what your Zope is doing.

Subject: [Zope] You are not allowed to access 'a particular str' in this

Message-ID: <4798B548.7060100@ze.tum.de>

Hi all,

I have a rather strange Problem.

I have a PersistentList containing PersistentMapping objects.

[{'Status': 'Read', 'Confirm': False, 'Read': DateTime('2008/01/24
16:03:32.508 GMT+1'), 'Expires': None, 'SenderID': 'DC83D1F1DB88CDE8', 'Date':
DateTime('2008/01/24 15:51:50.998 GMT+1'), 'Message': 'Da ist ein permission
test', 'ID': '20080124155150_4641@DC83D1F1DB88CDE8'}]

When do a tal:repeat="message here/getMessages" and a tal:replace="message"
everything functions as expected. When i try tal:replace="message/ID" I get an
 Unauthorized Exception "You are not allowed to access 'a particular str' in
this context"

I can access all DateTime objects. Only the strings a not allowed.

There is no difference when getMessages return of the Original list and when I
 build a new list with copies of the PersistentMapping objects.

To get this working I have to create new Dictionary from the Persistent
Mappings add them to an normal List and return this list.

ret = []

for test in self.msglist :
    temptest = {}
    for (key,value) in test.items() :
        temptest[key] = value
    ret.append(temptest)
return ret

That's a real performance killer as the list is read quite frequently.

Any Idea how to fix this.

Does this problem only occure with message/ID ? Or also with 
message/Message or message/SenderId ?

Which version of zope are you using?


Kind regards,

Reconfigure your "error_log" object to not ignore "Unauthorized" exceptions,
reproduce the error and then look at the corresponding traceback.

I expect that the "message" object implements a "__bobo_traverse__"
method (or gets one through "Five").
Zope is a bit stupid when "__bobo_traverse__" returns an object
without security declarations -- such as e.g. a string.
In this case, it insists that "getattr" must return the same object
and raise "Unauthorized" otherwise.

The problem is on all Strings. DateTime Objects working.

What happens when you add

to your type definition? (Good old Zope 2 magic, yeah ...)

Thanks to Andreas and Martijn for your help. I had already your
suggestions but it wasn't working. However, I have now been able to
upgrade to Five v1.4.2 (rather than v1.4.4) by simply un-taring it in
the Plone products directory - you both suggested.

It seems Five v1.4.4 is faulty. When I untar it in the Plone products
directory and attempt to restart the Zope client, the zeoserver.log
reports:
"
...

every few seconds.

Still, my problem seems to be solved since Reflecto v1.2 only requires
Five v1.4.1 or higher.

Thanks
James

This may be compatible with my assumption.

Check line 338 in "Products/PageTemplates/Expressions.py".
When this line is in the block handling the "__bobo_traverse__",
then you have confirmed my assumption.


In this case, you must either get rid of the message's "__bobo_traverse__"
or let it return an object with security declarations (such
as an "str" wrapper with an "__allow_access_to_unprotected_subobjects__=1"
and "__roles__=None") or ensure that a "getattr" results in the same
str or fix Zope.

Thanks Jens

The live server is a Sun server - the Zope installation was copied over from an older Sun server about a month ago, and seemed to run fine unless we try to log in.

The root folder of Zope does not have a MySQLUserfolder, but the main subfolder - which hosts the website - has.  When authenticating to the website (MySQLUserfolder) I get the traceback.  But I can also not authenticate to the ZMI (I get access denied with a known good password and with the emergency user.)  But I know I should have access to the ZMI, because I can copy the Data.fs to a test server and login to that.  So somehow now authentication is broken for both Zope and MySQL authentication.
This led me to think the problem is in the Zope files, and I ran a diff between my test system (Debian) and the live Sun server.

Many files differ, but in a way one would expect - the Python path is not the same, so the first line of every .py file is different.  Also, *.pyc and *.pyo differ - likely because of the different Python paths.  But a number of file names on the Sun server worry me.   They miss the last letter - for example __init__.p instead of __init__.py.  I worry that the system admins (who I haven't met yet) may somehow have managed to lose the last letters of some file names, although I have no idea how that would be possible.
Is it possible that Zope can run sucessfully with these incorrect filenames, and only the authentication is broken?

One thing that comes to mind is broken tar implementations on Solaris.  
Don't use their tar implementation, use gnutar instead.

Hi!
I don't understand quite well this explanation but it interest me a lot (as
you can read if you search for my all questions about __bobo_traverse__)
do it need I put the __allow_access_to_unprotected_subobjects__=1 in the
__bobo_traverse__ or in other place?

I my last try to solve this issue in my case I try the __roles__ = None but
this was an uncomplete solution

Please can you complete my information?

Thanks!

Hello All,

I am looking for zope products to allow visitors to rate news articles after reading them.

Thanks in anticipation for your supports.

Look at easyrating for Plone or "content ratings" for Zope-ish applications.

This looks like a broken "UserFolder" instance (one that cannot
be loaded).
As a consequence, its "validate" method cannot be found and
"old_validation" (usually no longer used in modern Zope versions)
is tried.

Check your logfile for warnings about not being able to load a class.

The Zope weakness becomes obvious when "__bobo_traverse__"
returns an object without security declarations.

To work around this weakness you have to ensure that
"__bobo_traverse__" returns an object
with security declarations (in fact, it need to be public).
This means, you must set the security declarations on the
object returned by "__bobo_traverse__".

Subject: [Zope] [buildout] bootstrap and develop
Message-ID: <27C043BE-FEAB-492D-B90E-F19E3A30DD2C@zscout.de>

Hello, I'm using the infrae.subversion recipe to collect various  
Products and packages from our subversion. The main goal here is, to  
not use svn:externals. But the buildout directive "develop=src/..."  
seems to have the requirement, that the packages are already present  
if bootstrap.py is called. So it is not possible to place packages  
there with buildout and get them picked up.

1. Is this correct? I searched and found others have the same problem.

2. What would be alternatives or how can this be changed?

Thanks for answers and hints,

Subject: [Zope] zope 2.9.6 stops servicing requests
Message-ID: <033c01c8613e$0612a150$0201a8c0@AJAX>

Hi

Several weeks ago I moved one of my machine to a new server and upgraded
zope from 2.7 to 2.9 as well as the database from mysql 4.1 to 5.0.38.
All seems to be going well expect that on a couple of occasions the zope
server has stop repsonding to request. The server is takeing 0% cpu and the
only way to get it going again is to re-start zope.
I can't see anything in the event.log file or on the machine (the debug info
is below)

Can anybody point me in the right direction to try and find out what is
happening

Look for the DeadlockDebugger and install that and follow the 
instructions. Hopefully it can help you debug what Zope is doing when 
it's not responding but still ticking.
Perhaps you've got some dead connections to the database that refuse to 
timeout.

Subject: [Zope] ZMI in zope 2.10.5 broken
Message-ID: <15125493.post@talk.nabble.com>


Hi everyone,

I'm new to Zope and have just installed Zope2.10.5. I have created a new
Zope instance in my home folder and then browsed to my servers ip address at
port 8080 and logged into the ZMI. 

This is the problem, the top and main frames of the ZMI render perfectly and
I can navigate to the links in the main window, however, the tree menu in
the left frame does not load. Instead I get this error:

Error Type: NameError
Error Value: global name 'util' is not defined

I have had a look through the mailing lists and googled for hhours and have
found no indication as to what could be causing this.

The only clue I have is that when I click on the 'help' link in the main
frame the left frame of the window fails to render, even though it is a
completely different url. I have tried this in both Mozilla and IE and on
several different computers, one on XP and one on Vista.  

Some information about my setup:

I am running an ubuntu 7.10 server, installed both Zope installations from
the .tgz files on Zope.org. Python version 2.4.4

please tell me what extra information I can provide, I have zero experience
with Zope and am finding it pretty tough to learn, so I know nothing about
standard log files or debugging.

Cheers for any help

Alex

Subject: [Zope] Package recommendations (?) for minimal ZCA environment
Message-ID: <2DBD6171D5E06F4E9B783D6E8E0DD8A802207D81@DESI.hollywood.sduniontrib.com>

All:

I figured I would survey this list for recommendations of zope packages
that have minimal dependencies -- specifically for non-web, non-ZODB ZCA
applications.  My criteria for this minimal environment:

1. No ZCML, ZODB, or zope.app.* dependencies.
2. Egg available in cheeseshop; svn is okay too (e.g.
zope.cachedescriptors trunk does not require ZODB; PYPI egg does at the
moment).  I will use zc.buildout and virtualenv for deployment
environment.
3. Not specifically targeted at web applications only.

Currently, I'm using zope.component, zope.interface, zope.schema,
zope.datetime, zope.event, and a related but small set of dependencies
installed from PYPI.

Background: I'm working on a set of components for working with
mass-media content that are to be generically useful across multiple
environments, application frameworks (web and non-web), etc.  The core
of these components depends on some zope 3 libraries, but my goal is to
keep dependencies to a minimum.  

A superset of this minimum framework would be used to deploy components
to specific application environments including basic automation scripts
to move content from one system to another, middleware applications
exposing these components over XML-RPC, web applications in Z3, Django,
and Plone/Z2.

Any recommendations appreciated.  Maybe compiling a list like this is
helpful for the community to reach out to non-Zope python developers too
-- makes the technology more approachable.

Thanks,
Sean

Hi Sean!

Some of the ones that we've compiled (visible via http://svn.repoze.org or 
http://dist.repoze.org):

repoze.vhm (virtual hosting services)
repoze.retry (retry a request when an exception is encountered)
repoze.tm2 (transaction management, depends only on the 'transaction' module and 
zope.interface, see also http://repoze.org/tmdemo.html ... note that "repoze.tm" 
depends on all of ZODB, "repoze.tm2" depends on only the smaller packages but 
does the same thing, at the expense of not being compatible with ZODB 3.6)

You might also take a look at repoze.zope2 to service Zope/Plone requests via 
WSGI: http://static.repoze.org/misc/developingwithrepoze-zope2.pdf and check out 
repoze.org in general, as your goals seem to closely align with its.

Dieter,

Apologies for jumping late in this thread but how precisely should  
"App.FindHomes" be imported?

And a related question.  Any suggestions on how to support multiple  
product directories like a non-zeo config?  I checked already and  
zeo.conf doesn't appear to support the "products" directive.

I see the same problem.

You can use the z3c.recipe.egg:editable recipe.  I briefly tried that,
but it did not work for our (Zest Software) internal password
protected subversion repository, where we keep the code for our
clients.  The recipe tries to easy_install a package but it fails as
it cannot use our repository without a password.

In all other cases it should work though.  I thought there was another
problem that I saw with it.  Ah yes, it throws errors when buildout is
used in non-newest or in offline mode.  I suspect this can be fixed,
but I never reported it.  Feel free to do so.

Anyway, the following worked last time I tried it:

=================================
[xm-development] 
recipe = z3c.recipe.egg:editable 
find-links =  
    https://svn.plone.org/svn/collective/xm.booking/trunk#egg=xm.booking-dev 
    https://svn.plone.org/svn/collective/xm.theme/trunk#egg=xm.theme-dev 
 
eggs = 
     xm.booking 
     xm.theme 
build-directory = src 
develop = true 
=================================

And then of course mention this section in buildout[parts] and add
{xm-development}:eggs to [instance]eggs and perhaps [instance]zcml or
wherever else you need them.

But if I do:

So to get the same effect for Zope, I have tried this in the zope.conf:

Unfortunately, this has no effect.  Any ideas?

Subject: [Zope] Cant access 'real' root folder in ZMI
Message-ID: <f8bea058ee.47a084b3@anu.edu.au>

Hi, 

I recently installed plone 3 on a RHEL 5 server and did some mucking around to get apache working with it. I mostly followed the 'apache-with-plone' tutotial on plone.org to do this. The way it is currently set is as follows:

-? Plone and zope installed on my server ( eg serverA or 10.10.10.1) running on port 8080
-? DNS set to point www.me.com to serverA
-? Apache set to ProxyPass requests from "me.com:80" to "localhost:8080" (I followed the turtorial mentioned above)
-? My Plone site accessable from either serverA:8080 or www.me.com

However, both these methods lead me straight to the plone website, not to the "Zope Quick Start" page and while i can access the ZMI from plone, serverA:8080/manage or www.me.com/managae, the root folder shown there is the plone site's root folder.

Even when i stop apache and access through servera:8080 i still get the plone site.

I need access to the 'real' root folder, ie the one with "Control_panel", to set some user roles and permissions, but i cant find a way. 

I think i must have changed a setting while trying to get apache going, but cant remember what I did and I cant seem to find anything solving this problem on the internet. Can anyone point me in the right direction to solve this problem.

Thanks Heaps,

Fergus

Another related question.  With respect to conflict resolution, is is  
safe to assume that products (with _p_resolveConflict methods) in the  
main Zope products directory are already available to the ZEO server  
without any special configuration?

The error occurs in the 'zlib' module, which is not part of Zope, but
a python library. Moreover, on my python installs, this is a C
extension library, not pure python.. From what I can tell from this
traceback, it appears you have a rogue zlib library on your path
somewhere, Zope 2.10.5 certainly doesn't include it.

I'm not sure how the rogue file got there but it was probably while I was
trying to install a non 2.5 version of python, I did have a lot of trouble
installing python with zlib included, I don't know if this is a common
problem. 

Anyway, I fixed the problem by removing and reinstalling python 2.4.4 with
zlib and that has solved the problem. Zope works perfectly now. Thanks
everyone for the help!

max-bytes is supported as of ZConfig 2.5.  I'm not sure what version
of ZConfig is currently being used with Zope 2, but would be surprised
if it weren't possible to use ZConfig 2.5 or newer (2.5.1 is
available).

Only if you installed the ZEO server instance from a Zope software;  if
you installed it via a "ZODB-only" installation, then the products won't
be available (because they aren't shipped with the standalone ZODB tarball).

Ah!

ZConfig 2.5 and newer include max-bytes and old-files in the basic
"logfile" section, but  Products.rotatezlogs provides more features.

This is too late.

The dynamic loader looks at "LD_LIBRARY_PATH" on startup
and then caches the value. Later modification have no effect
on the current process.

You need to set "LD_LIBRARY_PATH" before you start Zope.

Someone else reported about a ZEO patch that does the same thing
without a need to import "App.FindHomes".

If you have Zope installed and ZEO is running
in the Zope installation (shares its code), then "import App.FindHomes"
in sufficient to import "App.FindHomes".

>And a related question.  Any suggestions on how to support multiple

"App.FindHomes" can be controlled via the envvar "PRODUCTS_PATH".
If defined, it is a "pathsep" separated sequence of directories
where Zope should look for products.
It may contain "%(XXXX)s" patterns with "XXXX" from
"PRODUCTS_PATH", "SOFTWARE_PRODUCTS" and "INSTANCE_PRODUCTS".
In these cases, the pattern is replaced by the corresponding path.

You should ask Plone related questions on the Plone mailing list.

The magic you see is the effect of an "AccessRule" -- installed
by Plone.
I hate this kind of magic and my first activity has been to
get rid of it. AccessRules can be disabled by an envvar.
Then, you can access the Zope Root Folder. You can then see the AccessRule
and delete it.

I forgot the name of the envvar. Looks at the code.

Usually -- but of course not always.

If you use and start ZEO from a Zope installation,
then "lib/python" needs to be on "PYTHONPATH" such that
ZEO finds its code and supporting packages.
Then the content of "lib/python/Products" can be used
normally as package "Products". There is no magic needed for this.

Of course, you can start ZEO from a non Zope installation (e.g.
from a standalone ZEO installation) and then Zope's "Products"
will be unavailable....

FWIW, it is typically better to install mysql-python with an --rpath, e.g.

python setup.py build_ext --rpath=/path/to/mysql/lib
python setup.py install

This prevents you from ever needing to set LD_LIBRARY_PATH in programs that use 
the library.  You might need to change the mysql-python's site.cfg file too (to 
be able to find mysql_config).

Thanks.  Okay, then assuming you've installed ZEO from Zope software,  
if your third-party product includes conflict resolution by  
instantiating a class defined in the Zope product directory, then is  
it also safe to assume that this product resolution is still  
available to the ZEO server?  For example, if I have the following in  
MyProduct:

from BTrees import Length

class MyClass(...):
     _count = None

     def incrementCount(self):
         if self._count is None:
             self._count = Length.Length()
         self._count.change(1)

     def getCount(self):
         return self._count()

Then do I have to make MyProduct.MyClass available to ZEO or is it  
enough that BTrees.Length is available?

That is enough:  the Length class derives from Persistent, which means
that handle their own conflict resolution:  as long as your product doss
no conflict resolution of its own, it doesn't need to be imported by the
storage server.

Any plans to incorporate either of these solutions in the next  
release?  I would like to avoid trying to explain how to do this to  
users of a third-party product that needs to be accessible to ZEO.

Ahh... this sounds good.  So, assuming App.FindHomes in imported,  
then all I would need to explain is how to add the necessary "export"  
lines to zeo.conf?  (or maybe zeoctl?)

Great, thanks.

Has anyone given thought to maybe providing a more general class with  
conflict resolution in the core distribution?  The Length class works  
for simple counters and I guess it can also be used for just simple  
assignments, but what about something more complicated, perhaps with  
some sort of factory defined at the moment of instantiation?

Assuming this is even possible, having such a general purpose  
conflict resolution class defined in the Zope products directory  
might make it easier to distribute a third-party product that needs a  
little conflict resolution.  Just a thought.

Custom CR code is *hard* to get right:  most people would be better off
using stock code (e.g., on of the tree types defined in the BTrees
package, or Length).  Those who can get it right aren't likely to need
their hands held.  ;)

I meant easier for the end user, not the developer.  It's kind of  
complicated right now to explain how to set up a ZEO configuration to  
work with your third-party product.  Makes it a bit of hurdle to  
distribute such a thing for general use.

Oops, I just realized that Length won't work for simple assignments  
as the conflict resolution assumes it's trying to resolve a counter  
(which should have been obvious, I know).  Is there zope core class I  
can use for a simple assignment, that maybe resolves conflicts by  
just picking the last value assigned?

There is no such thing as the "last value" during a conflict (only three states: 
what's in the database, and the two conflicting states: what connection1 says, 
and what connection2 says).  If the values are always going to have a __cmp__ 
method or if they can be otherwise compared (like integers), and if you're 
willing to accept the "highest" of the three states, you might use the conflict 
resolution policy of Products.Transience.Transience.py.Increaser.

Great, that's exactly what I need.  Thanks.

I also noticed another interesting option for a counter at  
Products.Transience.Transience.Length2.

Nobody really uses ProxyPass any more nowadays. apache's RewriteRules
are just more flexible. That tutorial is outdated in this respect.

My guess: You probably mucked around with the "Mappings" tab in the
Virtual Host Monster. Bad idea. The VHM is to be left alone, any
Mappings should be set up using RewriteRule in the apache config.

I don't know how you can un-muck this situation in the VHM. Deleting the
VHM (e.g. through ftp or webdav) will likely not change anything, but
maybe give it a try after a good backup of the Data.fs. Maybe there is a
secret request variable to suppress the VHM mapping? But I don't know
it.

If accessing Zope through port 8080 shows the same problem, it's
unlikely a problem in the apache config.

Sounds like either an AccessRule or the VirtualHostMonster (VHM) is
putting you into Plone directly.

You can disable both AccessRules and the VHM by an environment
variable or with a URL path element:

- set the SUPPRESS_ACCESSRULE environment var

- add _SUPPRESS_ACCESSRULE  to your URL.

So http://servera:8080/_SUPPRESS_ACCESSRULE should solve this for you;
double check your VHM configuration if this works, it should be empty.

Or by a rule within your etc/zope.conf.

I am almost sure that the "import App.FindHomes" solution will
never go into ZEO. It would tie ZEO to Zope (which probably is
unwanted).

It would be nice if ZEO would learn configuration options
that would cover all of Zope's products locations.
But unfortunately, ZEO is part of ZODB and Jim
declared recently that he is the benevolent dictator for the ZODB
project and he will usually defer things which can increase the
complexity....

There can be no *general* class with conflict resolution.

Conflicts usually are fatal. Precise knowledge about the intended
use is necessary to determine whether and how a conflict can be resolved.

Take a look at the "Length" class. It resolves all conflicts in
a way compatible with maintaining the length of a data structure.

However, you must *NOT* use it to assign unique integer tickets
as it may return the same value in different threads.
Without conflict resolution you would get a conflict when
different threads take a ticket concurrently; with the
"Lenght" conflict resolution, the tickets are no longer unique.

Loby Jim that he accepts the patch.

Will Zope 2.10.5 satisify zope.app.catalog? Do I need to stick to a
particular revision?

Thanks,
