[Zope-dev] Re: ZOBD and pointers
[Yair Benita] Reading this answer I understand that anything I store should be persistent, even if its a list I don't plan to edit. [Tim Peters] I wouldn't say that. For example, for _most_ applications it would be foolish to create a subclass of Persistent to store an integer, as opposed to just storing an integer directly. I can conceive of (unlikely!) applications where there may be advantages to storing integers as perisistent objects, though. [Tres Seaver] As, for instance, where the integer changes much more frequently than the other attributes, which are large enough that re-storing them just because the integer attribute changed is painful. Yup, that's a possible reason. Another recently popped up, which I'll exaggerate to make the point: you have 100,000 distinct integer ids, and you have 10,000 objects each with a (Python) list containing 10,000 of those ids. If you load those all into memory, Python will allocate space for 1*1 = 100 million integer objects, and that will consume more than a gigabyte of RAM. But if integers are stored as one unique persistent object per unique integer, it can't require more than 100 thousand distinct persistent integers in memory (because that's the total number of distinct integer ids). The RAM difference is a factor of about 1000 (but ignoring that it takes more RAM to hold a persistent wrapper than to hold a straight integer). I'll note that IISets avoid this problem via a different route: they hold their integers as raw bits, not as Python integer objects. When you extract an element from an IISet, a Python integer object is created on-the-fly to wrap the bits. Making the attribute a persistent sub-object also eliminates the chance of a ConflictError based on changes to the other attributes. I didn't follow that one. If other attributes change, they can trigger conflict errors, right? This is the use case which drives BTrees.Length, right? The important part of that is its conflict resolution method, which keeps track of the correct final size of a BTree in the face of concurrent mutations. BTrees don't keep track of their own size because every addition or deletion would have to percolate the change in size back up to the root of the BTree, and we'd get conflict errors on the root object then. As is, most additions and deletions change only the leaf Bucket node where the mutation takes place, giving mutation often-useful spatial locality in the face of concurrent mutations. I wish we could do better than that, though: from what I see, most people don't realize that len(some_BTree) takes time linear in the number of elements, and sucks the entire BTree into RAM. The rest seem to have trouble, at least at first, using BTrees.Length correctly. I suppose that's what you get when a scheme is driven by pragmatic implementation compromises instead of by semantic necessity. Give enough pain, it should be possible to hide the BTrees.Length strategy under the covers, although I'm not sure the increase in storage size could be justified to users who have mastered the details of doing it manually (the problem being that many uses for BTrees never care to ask for the size, so wouldn't want to pay extra overheads for keeping track of size efficiently). ___ Zope-Dev maillist - Zope-Dev@zope.org http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )

Imaging object A with attributes 'foo' (a string), 'bar' (a normal Python int), and 'baz' (a hypothetical persistent int). Assigning directly to 'baz' would still conflict with assigning to 'foo' or 'bar'; however, the persistent int object might have an update protocol which made its value changeable without needing to rebind another PI into its parent.

Re: [Zope] accessing session data error
Hi:
Thanks to Michael Dunstan. I test with the recomendation of
Michael but I still get the error. In pages where I get the error, if I wait
some seconds and refresh the pages, I obtain the correct
information (no get the error).
I thinks that the problem maybe are similar to the guess of Michael,
but I test "breaking up ``init2`` into two scripts" and the error don't
disappear. :(
Any help will be useful.

Hi Leticia, The mixture of ``response.write()``
including _javascript_ to drive the browser to a new location
along with writing objects in ZODB all within the same
transaction can break some of the promises that you'd
normally expect Zope and a browser to keep. My guess is
that browser is being told to visit ``end`` before the
transaction started by ``init2`` has finished. Perhaps a conflict
error is causing that transaction to take longer than you expect.
Normally this would not trip you up as your browser does not
see anything until after the transaction has finished. (In
this normal mode you might see a conflict error rendered in
the browser if the publication machinery had to give up.)
For your example try breaking up ``init2`` into two scripts.
The first that writes the session data and then redirects the
browser to the second. The second then does not touch session
data and manages all the ``response.write()``s. And remove
the unused ``sessionData = context.REQUEST.SESSION`` from
``external``. Cheers Michael On

all: I think that I found a ZOPE bug. Is really
very important for me know what can I do for avoid it.
The first 9 steps are to recreate the situation and the
other steps are to provoke the error. Step 1:
Crate a folder called "reproducingError" in Zope Interface
Manage Step 2: create a page template called
"index_html" in the "reproducingError" folder with the
following content: " !-- index_html page
template -- form name="form1" method="post"
action="" input type="text"
name="user" input type="submit" name="Submit"
value="Submit" /form "
Step 3: create a python script called "init" in the
"reproducingError" folder with the following content: "
# init script sessionData =
container.REQUEST.SESSION sessionData.set("userId",
container.REQUEST.user) return context.init2_html()
" Step 4: create a page template called
"init2_html" in the "reproducingError" folder with the
following content: " !-- init2_html page
template -- a href=""passing face
2/a " Step 5: create a python
script called "init2" in the "reproducingError" folder
with the following content: " # init2 script
request = context.REQUEST sessionData =
request.SESSION sessionData.set('idService', 'testService')
context.first() return context.external(context)
" Step 6: create a page template called
"first_html" in the "reproducingError" folder with the
following content: " First Response
" Step 7: create a python script called "first" in
the "reproducingError" folder with the following
content: " # first script response =
container.REQUEST.RESPONSE str = container.first_html()
response.write(str) response.flush() "
Step 8: create an external method called "external"
in the "reproducingError" folder with the following
content, in where the function of the external method is
"communicationResponse" and the module is any name that
you give to the file: " # external method
import time def communicationResponse(context):
response = context.REQUEST.RESPONSE
sessionData = context.REQUEST.SESSION
strDetailEnd = "scriptwindow.location='reproducingError/end'/
script" for item
in range(1, 40): time.sleep(3)
response.write("Response iteration:" +
str(item)) response.flush()
response.write(strDetailEnd)
response.flush() " Step 9: create a
python script called "end" in the "reproducingError"
folder with the following content: " # end
script idService = context.REQUEST.SESSION['idService']
return "Fin - " + idService "
Step 10: open two explorer in wich call the object
"reproducingError" (Example: localhost:8080/reproducingError)
Step 11: enter an example text in each one.
Step 12: clink in the link of one of them, and 5 second
later clink on the link of the other explorer. The
waiting for around 5 second is necesary because with
other time interval not allways get the error.
Stpe 13: and wait the "Response iteration"... Please
if the error don't appear in any of the pages, begins at

Factory-based Type Information option of dropdown.
I just need to have the copy of it and to alter some fields.
Here's some code I stole from Chapter 8 of my book, were a
Folder-derived type is created in an install script::
from Products.CMFCore.Expression import Expression

# New 'NewsFolder' type based on folder
types_tool.manage_addTypeInformation(id='NewsFolder',

nf.manage_changeProperties(filter_content_types=1,

actions=nf._cloneActions()
for a in actions:
if a.id == 'view':
a.action = Expression('string:${object_url}/newsfolder_view')
nf._actions=(actions)
After a clone of the type is made based on Plone Folder, some changes
are made: contents are filtered, and only News Items are allowed; also
an action is changed to point to a custom template.
This is a better option than using the copy/paste API like you might do
in the ZMI.

[Zope] Set sort variables with nice url
Hi. I have a nice scheme for my ordering, sorting and batch paging my
summary columns for objects and sql data but I have been using urls
like
employee_edit_form?employee_id=42start:int=2sort=employeereverse:int=
0 in my lists up till now.
These would be tal:attributes in my zpt, (a string) for href attribute
so that you click to edit the appropriate record. I have hidden fields
in my edit form that accept the start, sort, and reverse in the request
so that when the edit is done there is a response.redirect to pass user
back to the index_html on the proper page in the batch.
I am trying to use the Allow Simple Direct Traversal under the
Advanced tab for ZSQL queries to give me nice urls when passing an id
parameter to a zsql query with results in an edit form. URLs like:
/employee_by_id/42/employee_edit_form
This works nicely except I need the edit_form to also get my start,
sort and reverse parameters and I am hoping there might be some way of
setting the request in the edit_form so it is possible to use this nice
zsql traversal feature. Can someone suggest a solution that would not
involve direct parameter passing in the url - but in someway of setting
the request so when the edit_form is called these other parameters are
available in the request. Note that start, order and reverse are
available variables in my index_html and change based on the batch page
and column heading urls selected. I have tried using something like
tal:define=dummy python:REQUEST.set('tmp_sort', sort) to see if I
could set tmp_sort in index_form and when edit_form called tmp_sort
might appear in the request. Alternatively is there some type of
javascript that might help with this to either pass the remaining
parameters or use history in some way?
On a second note, can someone advise me of what I need to place inside
the dtml-comment area in a filesystem zsql query so that it will use
simple direct traversal.
Many thanks,
David

Factory-based Type Information option of dropdown.
I just need to have the copy of it and to alter some fields.
Here's some code I stole from Chapter 8 of my book, were a
Folder-derived type is created in an install script::
from Products.CMFCore.Expression import Expression
# Customize types
types_tool=getToolByName(portal,'portal_types')
# New 'NewsFolder' type based on folder
types_tool.manage_addTypeInformation(id='NewsFolder',

nf = getattr(types_tool, 'NewsFolder')
nf.manage_changeProperties(filter_content_types=1,

actions=nf._cloneActions()
for a in actions:
if a.id == 'view':
a.action =
Expression('string:${object_url}/newsfolder_view')
nf._actions=(actions)
After a clone of the type is made based on Plone Folder, some changes
are made: contents are filtered, and only News Items are allowed; also
an action is changed to point to a custom template.
This is a better option than using the copy/paste API like you might do
in the ZMI.

Thank you very much, Cameron. Definitelly will use it next time. This
time I decided to create the separate content type, because seems like
I will need to change some methods of it. But I will definitelly use
your solution next time ;)

Re: [Zope] Zope External Editor Problem
Where is the ZopeEdit.ini file you're editing? According to the 0.8
code it should pick up the editor defined in the config file up and use
it exclusively in preference to any extension- or content/type- related
executables. The code first looks in:
os.path.expanduser('~\\ZopeEdit.ini')
(which on my system resolves to c:\Documents and Settings\chrism
\ZopeEdit.ini), and then looks in:
os.path.join(sys.path[0] or '', 'ZopeEdit.ini')
(the package directory, presumably).

Any help will be useful.

Hi Leticia,
Just double check that you are redirecting from the init2-first-half
to init2-second-half. Using something like the following in init2-
first-half::
response.redirect('init2-second-half')
rather than directly calling init2-second-half.

Re: [Zope] Newbie Questions - many-many relationships? Zope 2 or 3?
Thanks to those who posted suggestions - certainly gave me a few things to think about. Unfortunately I was left with one use Zope 2, one use Zope 3 and a use Plone, but maybe that's just a reflection of the fact that there's more than one Zope way to skin a cat! (yeah, I know I've over-simplified the answers - no offence is meant!) On another thread (http://mail.zope.org/pipermail/zope/2005-June/159738.html), someone said: The problem is that you develop using the ZMI. It's a bad pattern. Don't do it. but the Zope Book (2.7 version)'s chapter on Creating a Basic Application all seems to be through the ZMI. Now, Zope's original appeal to me was using the graphical interface provided by the ZMI to create a collection of objects which if you wire them up correctly will become an application, a view that I think is supported by the Zope Book. However, this view, and what I've read about Zope 3 seems to indicate that this way of doing things is deprecated. Am I correct here? Particularly, if I am building an app that I think I will want to add extra functionality to after it has been installed and is in use, is this a particular reason to avoid developing with ZMI? Say, for example that my Zope App in some way has a House object, which records the address, the owner, and a short description. Later on, I may wish to add further fields to record, say, the number of bedrooms, but the system is already in use - if I've developed in the ZMI, will this make it harder to make an upgrade? Now, if the answer to all of that is yes, then I think that steers me away from the need for TTW development (TTW = Through The Web = ZMI, yes?) which steers me towards Zope 3. I'm interested by the suggestions on how to handle the relations. Hmm, what I would start with is an attribute for a house containing a list of references to owners. And vice versa, each owner has a list of references to houses. I had thought of this, but my concern was about how to make sure that the two records are kept accurate - basically the suggestion is to keep two records saying the same thing, which just triggers alarm bells with me. Another suggestion was: Nah. You either let every PropertyOwner have a list of the ids of HouseProperty objects, or the other way around. Then you index this is the catalog so you can search. Tada! I like the sound of this a bit better - just keep records in one place. So, if I've followed, I let the the house knows who owns it, and if I go to a certain owner's page and want it to give me a list of all the houses she owns, it would do a search through all the house records to see where she's mentioned.

[Zope] TypeError: Cache values must be persistent objects.
Help!
I'm trying to develop a filesystem-based Product (here 'ABCD') and
unless I remove the ABCD folder from my Products directory, I get the
following error IN THE MANAGEMENT INTERFACE.
Is it possible to determine what's causing the problem? After multiple
restarts, I did a global Find in the ZMI and (I think) deleted all
objects of type ABCD Content. But still the problem persists (no pun
intended).
Gaah! How can I fix this?

Why should Zope be just as easy? Because Zope is hard. You can make some great sites/applications with Zope but for all except the very simplest you need . advanced understanding of html and xml or . a thorough grounding in programming principles or . a working knowledge of Python - and preferably all three. Most (not all) of the people who hang out here have all three of these skill sets, and like many skilled people, they find it hard to understand that the skills they have seem arcane to beginners. You should also understand that nobody (AFAIK) is 'them' with an interest in making Zope easy and helping you. You depend on the kindness of strangers, so politeness and gratitude pay. In addition, Zope is heading fast into even less friendly territory. DTML, which is technically 'mucky' but reasonably easy to grasp for non-programmers, is increasingly deprecated. Through-the-web editing likewise. I'm not saying these trends are bad, just that they are happening, they make the learning curve steeper, and that they lock out almost all casual users unless they have the skills noted above. The alternative in the Zope world is Plone, where you can get a site up and rolling in very little time (as long as you are happy for it to look and operate like almost every other Plone site on the planet). or there's PHP, where the communities are probably more newbie-friendly and there are loads of tutorials. or you could decide that Zope does some stuff which you must have, in which case David H's stereotypical response If you spent more time just *learning* Zope and HTML, etc and less time rationalizing your lack of progress everyone would be happy. is appropriate.

I would like to know that 'increasingly deprecated' means by everybody (I mean here: in the www-programmers-word), or just by Zope. Does this mean that it would be better to deep into ztemplates?

So you prefer to ignore it? Just how much time should you spend on something when you are deriving no benefit just increasing frustration? Sometimes, answering questions on the mailing list feels exactly like that :-P I was on a course over the weekend where ordinary people in their 70's with no technical ability were knocking together websites in just a few hours with no prior training and no understanding of the underlying concepts involved. Why should Zope be just as easy? I highly doubt the stuff they were knocking together was a sophisticated application, e.g. anything on the order of CMFDefault, not to mention CPS or Plone. There's a big difference between developing web apps and slapping together some static HTML. There is a quantum leap between the tutorial and being able to do anything useful with a website. What the tutorial needs to to handhold you through putting together something like the homepage of zope.org. That would be an immense tutorial! There are some case studies of similar sites in Andy McKay's excellent Plone Book. But they depend on reading and understanding many chapters before you get that far. Jon, I know this is frustrating for you. You are encountering the (in)famous Z-shaped learning curve. You have hit the upslope. At this point, the trivial stuff (mostly) makes sense to you, but there's a vast-looking chasm between where you are and where you want to be. We've all been there. It *does* get better. Really. But it can take months of perseverance to reach the other side. And there's not really any way to skip the hard part. You might find this interesting.

DTML, which is technically 'mucky' but reasonably easy to grasp for non-programmers, is increasingly deprecated. I just started to learn Zope recently.

I would like to know that 'increasingly deprecated' means by everybody (I mean here: in the www-programmers-word), or just by Zope. That's FUD and not true. DTML is not being deprecated, period. Don't believe anyone who says that. Everyone should choose the tool they work with best, and DTML is suitable for many people. There's more people who choose to use ZPT nowadays, but that does not mean DTML will be deprecated. jens ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
[Zope] Zope crashing after movin Plone site to RHEL 4
Hi, I have this 1.0.2 Plone site running for about two years, or so. It always ran smoothly. Recently, i've moved it to a new server running Red Hat Enterprise Linux 4. I've compiled Python 2.1.3 and start Zope with: exec /usr/local/python-2.1.3/bin/python $cwd/z2.py -L 'pt_PT' -u zope $@ Now, i'm having this big problem: Zope crashes every day once or twice. Onle restoring a previous Zope backup i can get Zope and Plone up again. Is there something wrong here ? Something specific to RHEL 4 ? Thank you in advance.

Don't compare PHP with Zope. PHP is a tiny language compared to the fat Zope frameworks. Working with Zope on the scripter level (ZPT, DTMl, ZSQL) requires similar skills as a PHP programmer. If you want to go beyond you have approach open-minded and come a with some solid knowledge in programming and understanding architectural issues in Zope. But when I read some questions here then I have the impression that people except that Zope solves their problems although neither they don't understand the problems themselves nor have the basic skills to reach the goal. That's not a but being newbie-friendly but one can expect as certain level of knowledge when you're working with Zope...e.g. the knowledge how HTML works (that's something kids learn at school nowadays). -aj pgpG7KMOJzwM4.pgp Description: PGP signature ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
