RE: [Zope] acl_users API

[steve smith]

I must be blind...

I've been through the whole book (I think), and can't find a shred of info
on manipulating acl_users with DTML. In one of the chapters it leads with
the tantalizing phrase "we'll see how to give users the ability to change
their own passwords later", but the trail goes cold.

I'm sure there is a way...

Re: [Zope] logging for virtual hosts

hi,

I have the same prob. Although I have not implemented it yet, I was
thinking of doing a python method that I could pass all the info into and

[Zope] How do I set the Title property of a File object from a DTML method

[magnus]

I have some of my own ZClass objects that may contain other ZClass
objects or Files.  Using a form and a method (that calls
manage_editProperties(REQUEST)) I can set all the properties of my own
ZClass subobjects.  But I'm unable to set the Title property of a File
object.  Is there a secret trick?

Wow, nice dumps...

So the root object contains a reference to oid 57, which appears to be
an instance in Product land having to do with DemoPortal. For instance,
maybe it's the ObjectManager instance related to the Product that goes
into the Control_Panel.Products area.

So...

app.something = app.Control_Panel.Products.DemoPortal
get_transaction().commit()

... just for instance.

Why would somebody do this?  I don't know.

BTW, I think object 2 is the child object list.

That's possible.  Still assuming oid 57 is the ObjectManager instance
related to the Product:

app.Control_Panel.Products.DemoPortal.foo =
app.Control_Panel.Products.ZDiscussions.propertysheets.methods.amethod
get_transaction().commit()

Why?  I have no idea.

To be honest, I have no frigging clue.  :-)  The "PRI" in your case is
created on Zope startup.  It's the persistent representation of the
on-disk DemoPortal Product in the Control_Panel.  Furthermore, it gets
re-created every time Zope starts (unless you're using ZEO).

There are talks about making on-disk products not have persistent
representations in the control panel products folder (not that this
would help your issue, but it might make things a little simpler).

As I read your problem report, if you wanted to try to solve the problem
via truncation, it seems you would have needed to chop the file at the
byte previous to the beginning of the transaction which first installed
the "PRI".  I presume that was too early of a transaction to be
feasible?  It seems a pretty low number.

Also, I presume this was an older version of Zope?  You imported an
object as superuser, which shouldn't be able to happen under Zope
2.2.X?  Was this an older version of the PTK as well?

Bummer.  :-(  But I still think your problem was caused by app-level
error and not ZODB-level error.  If I had time, I'd examine ZDiscussions
and the PTK to see if I could spot the problem.  But I don't.

[Zope] ZCatalog and random key error

[Bak @ kedai]

hello all
i'm about to venture into building a ZClass that will make use of ZCatalog.  
is it 'safe' now?  i see that my zope2.2.2 now haven't encountered any random 
key error yet.  what about others?

also, will iterating through catalog index faster than iterating through 
..say.. objectItems('meta-type')?

looking for insight, advice, holes to avoid, etc

thanks

Hi Morten,
Yes.  It's acting as if those little boxes were not checked! :)  As I was
replying to Jeff in a prior message, the mystery goes deeper.  I grabbed a
fresh copy of the latest CVS version, built it, set a superuser password
and ran it.  I then tried to visit the default index_html "Welcome to
Zope" page and was presented with a BASICAUTH type login box.  If I
explicitly set anonymous View permissions for the index_html (Welcome
to Zope) page, then I get in with no login as expected.  That isn't
normal is it?  Root folder objects would appear to be having the same
security setting acquisition problems as I was finding previously with
sub-folders and LoginManager.

I realize I'm on the bleeding edge of Zope running the CVS version,
but I heard the 2.2.3 version is due out RSN and figured maybe a little
"new version" pain now would be easier than upgrade pain later.  I'd sure
rather be saying "Here's a patch" than just "It's broke", but alas I
don't grok Python that well yet.  ("It's broke" still offers *some*
value, right?  :-)

To the Zope developers:  It seems pretty clear that Zope v2.2.cvs is
broken in regards to security settings acquisition.  Should I post to
zope-dev, or is there already a sufficient awareness/understanding of
the problem?

Thanks,
Charlie

SiteRoot doesn't mangle FTP paths, so you can get in there and remove
the base - no reinstallation headaches for the product, then, and you
don't have to restart the server.

Thanks for your response Jeff.  It seems we are in agreement.  The scope
of an acl_users folder needs to include its siblings and parent folder.
The only logical alternative I can think of is if the functionality
of acl_users, LoginManager, or whatever, was provided by some modular
component of the parent folder itself, instead of being represented as
just another object _in_ that folder.

Anyway, I did a sanity check against v2.1.2 using these exact steps:

1. Create an access_test folder with user folder and user interface.
2. Navigate to security tab of access_test.
3. Create new role "User", and allow "User" to View Objects and Access
   Contents Info.  Bar access by "Anonymous" by turning off "Acquire
   Permission Settings" for View Objects and Access Contents Info.
3. Create user "joe", password "blow", with role "User"
4. Bring up new browser window, enter the URL for access_test.

In that scenario, joe can view anything within the acl_test folder,
while anonymous users cannot, due to the objects within that folder
acquiring their security settings from the acl_test folder itself.
*That's* what I want!  It's *not* what 2.2.cvs is doing.

In fact it's even worse than previously described.  After pulling down
a completely new CVS image of Zope, I just happened to try visiting
the root URL of the new site.  Result?  I was prompted for a password
to visit the root (Welcome to Zope) page of a pristine, new Zope site.
I think this must somehow all fit together.  Unless there is something
critical about the new security model that I have missed, it looks like
there's a bug here.

As I think you indicated above, the type of security/acquisition model
that seems to be in place for 2.2.cvs poses far more serious problems
(i.e., needing acl_users *above* the root folder) than just setting
permissions on a bunch of modules.

Thanks again Jeff.

I figured it out.  With a little help from my friends.  This product
is missing a 'help' directory.  I'm not sure if this is a debian
feature or not, but attached is a patch to let zope load it whether
the directory exists or not.

I basically wrapped a try around the part of the code that looks for
the help directory and files within it.  This is the file
App/ProductContext.py, btw.

I'll see about fixing SiteAccess (and Plugin, which has the same
problem) for Debian.

Ciao!

Either one of the objects does not want to be accessed
or there is one that can be accessed but does not provide
access to "id".

In the first case, you could add the argument "skip_unauthorized"
to the "dtml-in" tag. This would simply skip the objects
you should not see (quite nice).

The second case is a bit more difficult.
You would either need to allow "id" access (i.e. 'View') for "Annonymous"
(for the refusing object) or give your method a proxy role
with appropriate privileges.


For your simple example, however, you can recode to avoid
these troubles:

[Zope] access to DTML's quoting and formatting(was: [Zope] ID = "somebody@someserver.com"... ?) (was: [Zope] ID = "somebody@someserver.com"... ?)

Zope *SHOULD* export all quoting and formating functions to
be used in expressions. Unfortunately, it does not.

You can emulate it with specialized DTML methods. As an example:
"url_quote":

Define the DTML method: url_quote as:
   
Ensure, there is no whitespace whatsoever before '<' or after '>'!

You call this function with: url_quote(text=)

As someone else already pointed out, you can use
"_.string.replace(eadr,'@','_')" if only the '@' makes
problems. But email addresses may contain other funny
characters not allowed in id's. Therefore, "url_quote" is
safer (but not completely safe -> '/').

What does that mean?

In which respect does it not work in lower level folders?
Exceptions, does not unfold, seems to be empty, ...?

Are you sure, that the "dtml-tree" does *NOT* sit in a DTML document
(when it does not work)?

A Zope explorer as you see it in the left frame of the management

Your traceback indicates, that the object itself does not object
to be copied. It's the destination that does not want the
object.

  The problem occurs in "_verifyObjectPaste".
  Its source comment says:

# Verify whether the current user is allowed to paste the
# passed object into self. This is determined by checking
# to see if the user could create a new object of the same
# meta_type of the object passed in and checking that the
# user actually is allowed to access the passed in object
# in its existing context.

Thus, it is probably a security issue:

  Either you are not allowed to call the ZClass constructor
  at the destination,

  or you are not allowed to access the object to be cloned
  at the destination.

It would be a list, if you added a "multiple" to your

This will always be true. It is constant (an expression without

What you mean is:

  

This will be true, if "money" has the value "'1000'" in the current
context.

Note the '...' around 1000! Without special Zope magic, request
variables come in as string values. The '...' indicates
a string literal.

You want to look at the upcoming Zope book to learn more
about the possible Zope magic.

No, you can't

 unless, you made it accessable from inside Zope.

You have various options:

  *  the excellent "LocalFS" product
  *  the "ExternalFile" product (which probably is excellent, too,
 but I do not know it personally)
  *  an external method returning the content of a file
 giving its filename (search the list archive to find
 one - with the associated *security* warning!)

[Zope] ZMethod (Safe)

[Spicklemire, Jerry]

Hello Linguistas,

Shorter is better. In this light, my recommendation was "mod", 
short for MODule, and / or  MethOD, but it didn't get into the 
Poll List.

> We've pretty much settled on restricted/unrestricted here.

Also, I suggested "strict" as a shortened form of "reSTRICTed". 
Perhaps to much overloading from compiler directives, but it 
is the root word, after all.

If it's not simple, it will get simplified in use, and then 
you've got some folks refering to things in "slang", which 
drives newbies bonkers. "Official slang" is preferable, at 
least then you have some chance of usage being consistent.

Re: [Zope] Is data.fs corrupted?

[Bill Welch]

Eyeballing my problem Data.fs (I kept a copy), I see something different
than you describe.

What I take to be the root object (OID 0) refers to a record in what
appears to an instance of something to do with PTK (OID 57). A separate
record in the PTK related instance (PRI) refers to a record in what seems
to be the ZDiscussions *ZClass*, not an instance of ZDiscussions.
Interesting that the first (and problem) record of the PRI has the next
OID after that of the last OID of the ZClass. Could it have orginally been
part of the ZDiscussions install? I don't remember when I installed what.

See snippets of dump and tranlyzer at end of message. N.B., the Data.fs is
from an Intel machine (you have to swap bytes on the hex side to read it
correctly).

I tried the reinstall, delete instances method with no improvement. It
didn't seem to me that truncating would have helped me either, considering
that I would have had to truncate back to and including the root :-).

I recovered by exporting all my objects, starting a new ZODB, and
importing my objects.

What your method is doing, is stepping through every object at the root of
your Zope server. Not every object there is accessible by anonymous. Even in
a fresh Zope installation, Control_Panel is restricted to managers, so that
is the likely culprit.

To get around this problem, there is an argument for dtml-in called
"skip_unauthorized" which will automatically skip over any objects that the
current user is not authorized to access.

Changing your dtml-in statement to:


Will prevent this error. However, you will get every little object in your
root directory. So, standard_html_header, index_html, standard_html_footer,
etc. will appear. If you want to exclude these, specify just the meta types
you want to objectValues. For instance, to show only folders try this:



To show folders and DTML documents, try this:


etc., etc.

Hi Kathy,

open a command shell, change to the dir, where the wampum file resides.
Enter 'dir' and you'll probably find out that the file ends with the
extension '???.tar'.
copy the file from '???.tar' to '???.tar.gz'.
Then try to open the copied file with WinZip.

[Zope] Products, ZClasses and CatalogAware-ness

[Aaron Straup Cope]

Hi,

Could someone clarify the following for me:

I would like to create a Product that instantiates itself with a ZCatalog
and a search interface "built-in". I'd like make all the Product's
ZClasses update the catalog whenever they are changed. 

If I make all the classes catalog-aware and point them to the name of the
"root" ZCatalog, will they (re)index the root catalog or a catalog local

Oh yeah, cookies. Okay.

Is there a workaround/Product that solves this problem? If it's just
a cookie thing, I don't know what it would be but I figure it doesn't hurt
to ask.

[Zope] ZCatalog Range Weirdness

[Jeff Hoffman]

Hello,

We have an interesting situation, here, and I can't seem to put my finger
on what's going on.

Let's say I have two different classes of objects being cataloged. The
first class, Class A, has a floating point attribute myFloat. The second
class, Class B, does not. 'myFloat' is an index in the Catalog.

Let's say the makeup of class instances in the catalog is 50/50 Class A
and Class B:

  Instance1 (Class A): myFloat = 0.5
  Instance2 (Class B)
  Instance3 (Class A): myFloat = 0.65
  Instance4 (Class B)
  Instance5 (Class A): myFloat = 0.55
  Instance6 (Class B)

I queried the catalog with:

  Catalog(myFloat=0.0, myFloat_usage='range:min')

Expecting to get record objects representing:

  Instance1 (Class A): myFloat = 0.5
  Instance3 (Class A): myFloat = 0.65
  Instance5 (Class A): myFloat = 0.55

Since objects of Class B do not have myFloat, and would not be included in
the myFloat index. Instead, I get:

  Instance1 (Class A): myFloat = 0.5
  Instance2 (Class B)
  Instance3 (Class A): myFloat = 0.65
  Instance4 (Class B)
  Instance5 (Class A): myFloat = 0.55
  Instance6 (Class B)

In other words, I get all objects back, whether they have a myFloat
attribute or not. Interestingly, if I change the query to:

  Catalog(myFloat=0.5, myFloat_usage='range:min')

I get the expected results. Using 0.1, 0.2, 0.3, or 0.4 does not work; 0.5
seems to be the magic number, which I find curious given that 0.5 is the
minimum value present in any of the instances of Class A.

Can anyone shed some light on what's going on, here? How do I ask the
Catalog to return all instances who have a value, any value, for myFloat,
but none others?

Thanks in advance,

--Jeff

Here's my guess: you have a complex XML document.  As you explore the
document, Zope is setting a cookie that reflects the list of branches
you have opened.  After opening a large number of branches, you reach
the limit on the size of a cookie (somewhere in the range of 1024 or
4096 bytes), making it so that the compressed data stored in the cookie
gets truncated.  zlib then emits this cryptic error message.

RE: [Zope] FW: [Zope] adding properties to all existing docs

[michael angelo ruberto]

However, I would not make such changes asynchronously.
I would use "ZopeFind" to locate all objects that need to
be updated and then do it.
Maybe, its a matter of personal taste ...


Dieter

this is an interesting idea. another thing i might try is running the script
from Xron and ZopeFinding the objects. in this way the task is completely
automated and will free me from having to run it whenever new objects are
added.

[Zope] zlib.error : huh?

[Aaron Straup Cope]

I am trying to understand what exactly is going on when Zope returns an
Error -5 page.

Normally, this only happens on the left hand navigational menu but today
it happened while I was expanding an xml document/tree object from the  
Examples package for the XML Document product.

I've tried searching Google, the Zope site and the mailing list but to no
avail. Could someone please explain what's going on here? Is it me? Is it
Zope? How exactly do I prevent these errors from happening?

[Zope] security dilemma?

[Zhen Zhou]

please bear with my ignorance, because this is the first couple of day
I ever try Zope. It is super cool, but I should say that the
documentation is far from satisfaction.
Here is my problem:
The only API I can find to alter the properties of some object is
"manage_changeProperties". However, in order to execute this method in
my script, I have to give the "Manage properties" permission to
everyone, which may lead to severe security problems because the
method "manage_changeProperties" is web accessible, so a malicious
user can bypass my script and execute this method to change the
properties to whatever he want.
My questions are:
1, is there any API that can change properties of some object but can
not be accessed from the web?
2, is there any way to store a small piece of persistent data beside
using properties?

Thanx.
Derek

Since you would normally *say* just ZMethod, I like the suggestion of using
"Python ZMethod" and "Python ZMethod (Unrestricted)", vs. spelling out the
(Restricted) in the first one.  After all, are we going to have a "DTML
ZMethod (Restricted)", or a "SQL ZMethod (Restricted)"?  It make sense to
keep the "normal" (restricted) methods, that will/should be used more often
than not, labeled as plainly as possible.  The unrestricted version could be
the exception and labeled as such.

For example, if we do decide to create an unrestricted DTML method, it would
seem unnecessary to rename DTML ZMethod to include the restricted label.

This is the way Zope has always behaved, unless my memory is failing me.
Here's a thought to consider: In your model, the root acl_users would have
to appear _above_ the root folder (/) in the hierarchy for things to
function correctly. As it stands, acl_users in the root folder affects all
things in the root folder and below. As it stands, your acl_users (in
acl_test) affects all things in your acl_test folder and below. This is
consistent.

If you have 50 or so objects, and setting permissions is the obstacle,
simply write a Python Method (or DTML, if you prefer) to iterate over the
50 and tweak them. Then, you won't have to manually do the work through
the management interface.

There is also ZopeShell:

http://www.zope.org/Members/sf/zopeshell

and e.g. Cadaver if you want to use filetransfer via webdav (but lost
the url unfortunately, but from webdav.org you should be able to find it).

My problem though with all these things is that the file you edit is not 
automatically uploaded when you save it. Usually you always have to quit
the editor and do an ftp upload yourself as the ftp (or ZopeShell) always
work on a local copy of the file and do not notice if you save it (well, how
should they do it anyway ;-))
So some sort of ftp filesystem would be nice to have :)

address this.  I had posted about this on Zope-dev because I'm running the
CVS version, but no response.  Also more research has yielded more info.
I first discovered this issue with LoginManager, but the same problem
occurs with standard acl_users too.

First, 'Figure 1:'

/ (Root Folder)
/ acl_test (ACL Test Folder)
acl_users (User Folder)
index_html (Test Document)

Now, referring to figure 1 (above :-), changes to security settings
for the acl_test folder are having no effect on access to index_html.
Only when I change the security settings on index_html itself, can I
control access to it.

So what this seemingly boils down to is that as of v2.2.whatever,
an acl_users folder does not protect its siblings and their kids by
acquisition of security settings from the parent folder.  Instead,
sibling objects must have their security explicitly set.  Meaning that
instead of setting permissions on the parent object and being done
with it, one now has to set permissions for each and every sibling.
In my case that's over 50 objects and I'm not done coding yet.  Ouch!
This *can't* be right, can it?

Thanks for any clues,
Charlie

yup :)

try

  
This is not much
  
This is OK
  
This is very much
  
   This is not 1000, 5000, or 1
  

the  tag iterates over a list, which isn't appropriate here.

The  is not right. Use dtml-in if you want to iterate over
lists. So in your case you should try:



This is not much!


This is ok!


This is very much!


(or use  in this case)

This now makes a string compare as usually form parameters will be passed
as strings if you don't tell Zope to do it different. In order to e.g. let
it pass integers, you might try in the form:


...

Then you can say , etc.

[Zope] logging for virtual hosts

[zope]

We are using SiteAccess to have multiple virtual hosts on one Zope
Server. We would like to provide our customers with stats reports
based on the zope log. But entries in the log don't contain any
distinguishing information about the virtual host to which the entry
applies. Short of hacking zope, is there a way to modify our zope
environment to to have the requested hostname included in the log
entry?

We know that we can use PCGI thru apache and have apache do the
logging. But I'm hoping to avoid that.

[Zope] RE: Wampum Generator (tar in WinZip)

[Harris Peter]

Hi
Just want to mention one pitfall in WinZip - by default it CR/LFs
all files
extracted from a tar archive (unless you turn that option off).
Note that
the option is NOT on the "extract files" dialog. 

It hosed 150Mb of .deb files today - and I didn't realise until I
had
burned them onto a CD.  I couldn't believe that was what it was
doing at
first. "Nah", I thought, "how would it know which files were
binaries?"
Turns out it doesn't know. It doesn't care either.

In case you want to avoid this happening to you, note that
PowerArchiver
is more or less like WinZip but it can handle bzip2 as well, and
it's FREE.

Re: [Zope] newbie question

[Paul Zwarts]

Another thing you can do, not sure if Im using it right, but the effect is
good...

   
  
You must specify a First Name.


  
  
  
   

I have a support call form that is filed and submitted, and after the button
is pressed, a seperate validate method is called (can be in any document)
which will stop the processing if something isnt there and will show a red
error text at the top of the form that still contains the information.]

Its nice becuase the info stays there and doesnt take you off to a blank
screen with a few words.

[Zope] Security and Acquistition Problem

[Charlie Wilkinson]

Greetings,
I had posted about this on Zope-dev because I'm running the CVS version,
but no response there.  Also more research has yielded more info.
I first discovered this issue with LoginManager, but the same problem
occurs with standard acl_users too.

the security settings on index_html itself, can I control access to it.

So what this boils down to is that as of v2.2.whatever, an acl_users
folder apparently does not protect the folder it's in (parent folder),
but only it's sibling objects and below.  Meaning that instead of setting
permissions on the parent object and being done with it, one now has to
set permissions for each sibling.  In my case that's 50 or more objects
and I'm not done coding yet.  Ouch!  This *can't* be right, can it?
I know there's a lot that's happened with the security model, so I'm
really *really* hoping this is just a bug that's crept in.

Thanks for any clues,

[Zope] Uploading textfiles into Zope using LoadSite

[Jean Jordaan]

Hi Vimmers

I'd like to do a show-and-tell about how I

- uploaded a bunch of textfiles into Zope (by making use of
  'load_site.py')

- and turned them into ZClasses (using a DTML method).

This is not a flashy "here's how to do it" piece -- it's really a
request for advice on how to do things better, and a step-by-step from a
relative beginner, for other relative beginners.

OK, to business. I used 'loadsite-1.4.0-test.tgz'. From the README::

LoadSite version 1.3
Based on load_site.py from Digital Creations

Modified by Oleg Broytmann <[EMAIL PROTECTED]>
Modified by Itamar Shtull-Trauring <[EMAIL PROTECTED]>
wxLoadSite uses code written by Amos Latteier, and uses Fredrik
Lundh's xmlrpclib.

(Is there a newer version available?).

I started from a flattext database, with a structure like:


ID|penname|pensurname|notes|title|vol|nr|year|printed|text|name|surname|date
|nick|email

That is: 15 fields, pipe-delimited, containing different kinds of data
(strings, multiline text, dates, email, ...). Here is a shortened sample
record:

66|Zandra|Bezuidenhout||A room of my ownNee|A room of my own~nl~-
garden view,~nl~computer -,|||1998/7/23|zandra|[EMAIL PROTECTED]

I wanted to get the individual fields into Zope: for example, as
properties of the DTML Documents that LoadSite creates. To do this, I
had to hack on LoadSite slightly. I noticed that it found the body
attributes and aggregated all of them into one property (in
'htmlutils.py'). I guessed that I could import these attributes as
properties. To do so, I made the following changes to 'htmlutils.py'.
Originally::

*** 95,98 
if not self.seen_startbody:
self.seen_startbody = 1
self.accumulator = ""
self.bodyattribs = join_attrs(attrs)

I changed this as follows::

--- 95,99 
if not self.seen_startbody:
self.seen_startbody = 1
self.accumulator = ""
# njj: self.bodyattribs = join_attrs(attrs)
self.bodyattribs = attrs

This way, bodyattribs is not changed into a string like 'name="value"
[...]', but remains a dictionary { penname:Zandra,
pensurname:Bezuidenhout }. Then I had to change how they were fed
into Zope. To do this, I changed 'Uploader.py' from::

*** 113,115 
  if bodyattribs:
self.call(object.manage_addProperty,
 id="loadsite_bodyattribs", type="string",
value=bodyattribs)

To::

--- 113,128 
  if bodyattribs:
  # njj: start
  for attrname, attrvalue in bodyattribs:
  if attrname == 'text' or attrname == 'notes':
  self.call(object.manage_addProperty,
  id=attrname, type="text", value=attrvalue)
  elif attrname == 'date':
  self.call(object.manage_addProperty,
  id=attrname, type="date", value=attrvalue)
  else:
  self.call(object.manage_addProperty,
  id=attrname, type="string", value=attrvalue)
  # njj: end

# njj: self.call(object.manage_addProperty,
# njj: id="loadsite_bodyattribs", type="string",
value=bodyattribs)

This works :)  Unfortunately, it's a hardcoded hack that will only work
for this particular database. To be useful, you should be able to tell
LoadSite to snarf the attributes of  tags as properties, paying
attention to the ':type' convention of indicating the format of data.
But I don't understand sgmllib well enough to do that ..

I ran the flattext database through a pre-processor
('http://www.htmlpp.org', for the curious) to get files (named '1.html'
and so on) that look like this::


A room of my own -- Zandra Bezuidenhout




When uploaded by LoadSite, this creates DTML Documents with 15
properties each. Now to get them into ZClasses. Here is the DTML Method
that does this::


  
  
















  
  


  

  

  
  


  

  

  

  


It iterates over all the DTML Documents in the 'DTML_texts' folder,
and creates a 'ZClass_texts' folder inside it. If no folder 'nick'
exists, it creates one; and inside the 'nick' folder, it creates
'Text' ZClasses named '1', '2' and so on (discarding the '.html' bit).
In this way, each author's texts are collected in their own folder as
ZClasses. Nice!

The author folders will probably become ZClasses subclassing 'ZClasses:
ObjectManager'.

TODO: for each author, a user with default password should be created.

Zope objects basically need to inherit from OFS.SimpleItem (or an analogue)
for them to be "web manageable".  If a non-builtin Python object inherits
only from the "Persistent" class, it can be saved into the ZODB, but it will
not show up in the web interface unless you define certain methods on it to
make it act like a "SimpleItem", and unless you add it to some internal Zope
data structures that populate its ZODB container (such as the
ObjectManager's "_objects" list).  This is generally done for you by Zope
and you need not think about it.

But problems may happen when an application places instances into the ZODB
of non-web-manageable, non-builtin objects as attributes of normal Zope
objects.  If these instances aren't cleaned up in the process of the
deletion of whatever bit of Python code created them, they're "orphaned".
When they're orphaned, some application code may attempt to initialize the
object's instance (for whatever reason) in order to make use of them, and
because the ZODB can't find the class of the instance, it complains.  It
complains by raising an exception.  Zope's supposed to catch this and do the
right thing, but it evidently doesn't sometimes.

You can "fix it" by restoring whatever class the instance depends on and
subsequently use the debugger to delete the instance from the ZODB.  But
I've had it happen to me where it was just easier to truncate the
FileStorage I was working on than figure out exactly what was going on.
This is bad.

> What I really don't understand is why seemingly unrelated products fail
> as a result of the orphan instances.

Neither do I completely.  This may be bad exception handling in Zope itself.
When a Product is initialized, sometimes you'll see the failure of one
Product initialization break others.  Usually, it's the case that these
Products *are* related in some way.  It'd be interesting to investigate some
of these failures where the failure to load an object seems to break other
"unrelated" objects.  I'd imagine we'd find an unobvious relation between
the two objects.

> Is is because new products are
> trying to get an oid which happens to be used by the orphan?

No... the ZODB manages the distribution of oids, Products never need worry
about them.

I think it's safe to say that you probably need to pay more attention when
writing ZODB-based apps because you don't have things like constraints to
prevent you from shooting yourself in the feet with both barrels.  :-)  That
said, it'd probably be more accurate to call the result of this family of
errors "Zope corruption" than "ZODB corruption".  Again, I don't disagree
that this distinction is really superpedantic on some level.  It would
appear that we need to work on Zope exception handling as well as tools to

[Zope] newbie question

[Stephan Goeldi]

I want to select from a select menu, 3 amounts: 1000, 5000 or 1. After 
this, the form action method should reply:

- "this is not much" if 1000 was selected,
- "this is ok" if 5000 was selected,
- "this is very much" if 1 was selected

Now my form method looks like this:


How many money?

1000
5000
1




and the form_action method is this:


   
  This is not much!
   
   
  This is ok!
   
   
  This is very much!
   


I am sure that there is an error in my thinking of these tags.

TIA

I often work from emacs, accessing the ZODB through the Zope FTP Server
on port 8021.  The syntax for ange-ftp is
  /user@localhost 8021:/your/zope/object
(you can get the space with C-q )

Re: [Zope] Is data.fs corrupted?

[Stephan Goeldi]

I just asked the question lately, if it is safe to simply delete a Product 
in the lib/python/Product folder, if it is not deletable via the 
Control_Panel. Some told me that it is no problem. Now I am more unsure to 
delete the stuff.

[Colin Leath]

For the past hour and a half I have only once been able to get through to
zope.org. 
lists.zope.org/mailman/listinfo is accessible, however.
A zope.org-status mailing list might be helpful, like the egroups-status
list, since Zope work is so dependent on the site.

I've been trying to read product descriptions. Is that information
available anywhere else?

Second, I thought there was a searchable archive of the zope mailing
lists. I just found it in my
bookmarks: http://zope.nipltd.com/public/lists.html
but I was not able to find this link on the lists.zope.org url referenced
in the mailing list digests... the list manager might want to change that.

Third,
I'm trying to figure out ways of managing/developing with Zope from a
unix console, using text editors, text browsers and so on.
I have no doubt that others would rather not have to use a mouse and GUI
to work with Zope.
I have already found http://www.zope.org/Members/sf/zopeshell
But it says it does not work for 2.2

Could someone please point me to documentation about console-based zope
management? If it's easy to find on the zope site, I will find it when I
can get through again.

thanks,
Colin

[Zope] Job offering - England

[Erik Enge]

Zopistas, wanna get paid?  :)

Zope/Python programmer wanted to work with one of our clients in
England.  

A team from Thingamy (http://www.thingamy.com>) have for some
months now been developing a Zope application for a client in
England.  The client's main work is resourcing (ie. matching candidates
and clients and typing up contracts). 

Our client has, of course, got access to the source code - and thus they
want to continue developing the application after they recieve it from
us. We need a person that can travel to their offices once a week, and
spend approximately 2 days a week continuing development of the
application (the amount of work depends highly on what our client wants
done).

The application is written in Python, the interface is in XHTML 1.0
STRICT.  You should be an experienced Python programmer, and should have
spent your time in the Zope source code :-).

I will take you through the source code, and will also be your contact
person when questions about the source code, class structure or anything
of that sort arrises.  It would be desirable if you could overlap with us
(ie. start coding one month before we stop, so there would be some feeling
of consitency - and it would also give you a great opporunity to ask
(nearly) all questions).

* Start date: within 2 months (room for discussion).
* Salary: up for discussion.

If this sounds interesting (or if you want to ask questions) please email
me.  (Please note that this is not a fulltime job, so it would be
benefitial if you lived near their offices and had access to other work
aswell.  Their offices are 40 minutes by train from Waterloo station.)

Thanks :)

Enough! 
Imagine you actually and really do change the name of Python Method or
much worse the names of all XY Methods. Would that automatically change
all the Guides, How-Tos, Tips, Books, Emails, Articles, Sourcecode and
whatever it is we call Documentation? No it would not!

I herewith predict that changing the method names will add a layer of
confusion Zope just does not need.

Re: [Zope] RE: Wampum Generator

[Oliver Bleutgen]

> It's a Winzip thing. I'll bet wampum generator is a .tar file, just rename
> it to a .tgz file and  it should open just fine.

Just some thoughts/guesses:

I'll bet Kathy uses Internet Explorer. Don't know about Netscape, but
it becomes more and more difficult to get IE _not_ to try to be "smart"
about any file you download. In this case I think there's some kind of 
transparent mechanism which kicks in and tries to transparently decompress
files of type  application/x-tar. 
Guess it's a helper for compressed vrml .wrl.gz (or similar) files.
In this case renaming to .tgz works, but I think I saw the same mess the 
other way around when IE didn't remove the .gz suffix but nonetheless
transparently decompressed the file.

These things are extremely annoying when dealing with relativly 
unexperienced clients who, say, just want to _download_ an .avi
file with a left-klick. MS has implemented a lot of magic there, 
AFAIK IE even tries to guess the filetype by its content in some 
cases and then ignores each and every http-header which might 
suggest otherwise.

Adding "Content-Disposition: attachment" as a http-header seems to help
(for the .avi case).

cheers,
oliver

Re: [Zope] Is data.fs corrupted?

[seb bacon]

Could I just butt in here and try and clarify what I've understood from
this thread so far?  I'm feeling a bit dumb about it but I'd really like
to sort it out.

1) This problem is definitely a programming error
2) It arises when a product has a component which isn't 'registered' as
a zope object, so it's not cleaned up when the product is deleted

Is that right?  What would 'registered as a zope object' mean in this
situation?  Are there any other circumstances under which you end up
with orphaned instances?  *how can it be fixed?*

What I really don't understand is why seemingly unrelated products fail
as a result of the orphan instances.  Is is because new products are
trying to get an oid which happens to be used by the orphan?

If so, I don't think it's really so wrong to call this ZODB corruption,
although I take your point about the ZODB being stable.  In your perl
analogy, it's as if you are using two tables to create a parent / child
, one to many relationship.  You then deleted a parent row but forgot to
delete the corresponding child rows.  You data is now corrupted. 
True to your analogy, this arises in sloppy programming,
not in Oracle or whatever.  However, when you create the tables in
Oracle, you can place constraints on the tables so enforce the integrity
of your data, to protect against this kind of programming.  In a similar
way, I think it's too easy to end up with corrupted data in the ZODB.
Or perhaps I'm just particularly unlucky in the products I choose to
use?   

cheers,

seb

Re: [Zope] Cloning a ZClass-Instance

[Sven Hohage]

Once again thanks to you, but I can't figure out why cloning it's not
possible.
The object is a simple zclass with the baseclasses ->ZObject,
ZObjectManager<-
Nothing special.
I know that cloning a catalogaware zclass it's not working but
object-manager??
That's the complete traceback:

[Zope] ZMethod and language variants

My proposal that ZMethod be used generally for anything that Zope
regards as a method would mean that there already are other language
variants, such as DTML ZMethod and SQL ZMethod.
