different ways to secure the session. 

For example, ther would be cases where I would implement a 
client-checking mechanism based on both IP address and browser 
time-limited cookie. This would allow me to follow sessions on 
people refusing cookies and on people behind "IP dancing" 
proxies. I would loose session state for anyone both refusing 
browser cookie and being behind "IP dancing" proxy. This would 
be an acceptable compromise if I am manipulating highly private

In other cases, I could accept lower-level security related to 
the less privacy.

In earlier Zope versions, a method without a permission meant

Thus, you must provide a permission for "read".
Unfortunately, "read" is not a method of "LocalFS" but from
the Zope objects wrapped around the files.
You, probably, will not want to change the respective Zope

The quickest solution for you would be an external method
that gets the file, performs the "read" and returns the result.

Alternatively, you may subclass the Zope object classes,
provide a permission for "read" and use them in

[Zope-dev] How to add a SessionID to each page

2000-10-04 Thread Loibl Johann

Hi,
I would like to add a SessionID at the end of each requested URL because I would like 
to know which pages were requested by one user in one session.
For example like AMAZON does it:
www.amazon.com/books?SessionID=123456 http://www.amazon.com/books?SessionID=123456 
My problem: 
There are to many pages belonging to my homepage that I can't rewrite each link like: 
a href="next_page?SessionID=dtml-var SessionID"next_page/a

Also I tried to pass a SessionID with the help of SiteAccess but a automatic insertion 
of a random ID doesn't work at my machine.

Could anyone give me please a helping hand?

  The ValueError is being raised in field2required, but I see no parameters in

  somehow the RESPONSE parameter isn't getting set (it's the only

I suspect the problem comes from a "POST" operation.
You will not see POST operation parameters in the web server log
files.

It is highly unlikely that a missing RESPONSE causes the problem.
Such an error would be handled at a different place (I think
in "mapply").

At line 444 of "ZPublisher/HTTPRequest.py", you will see the following
code:
if flagsCONVERTED:
try:
item=converter(item)
except:
if (not item and not (flagsDEFAULT) and
defaults.has_key(key)):
item = defaults[key]
if flagsRECORD:
item=getattr(item,attr)
if flagsRECORDS:
item.reverse()
item = item[0]
item=getattr(item,attr)
else:
raise

Add "print key; sys.stdout.flush()" before the final "raise".
This will print the corresponding "key" (with is missing).

To get more information: the variable "fslist" contains all
parameters. It is a list of objects. Each object has a "name"
attribute (which gives the form variable name or 'key'),
the object either has a "file" or "value" attribute.
You may look at line 370, to see how it is processed.

You can test your debugging code in your test environment.
Simply create a form with a "xxx:required" variable name
and do not provide a value.

Zope is just simply not suited to lots of writes. Use Access as the

Subject: [Zope-dev] Zope Suitability for Computer Lab Project


Greetings from a "potential newbie".

I need to build an application for recording clients who use a computer lab.
The idea is to collect demographic information on clients who use the lab,
and session information such as date/time and whether the client attended a
class.  Objects include clients, sessions and classes (or I think they do;
I'm more used to thinking in relational terms.  I was going to build it in
MS-Access, since it's available on all the PC's in the lab, can do
everything I need (including reporting), and I know it well; on the other
hand, there are undeniable advantages to having something server-based with
minimal client dependencies.

I'm pretty sure it would take me more time to build it in Zope than in
Access, mainly because I don't know Zope yet.  What I don't know is whether
this is an appropriate application for Zope; it's not really what I think of
as "publishing"; more like data acquisition and subsequent reporting.

Observations based on experience will be gratefully received.

Thanks in advance,

[Zope-dev] ZODB

2000-10-04 Thread Roch'e Compaan

I am getting really funny problems with my Zope installation and I have no
idea where to start looking.

I for instance deleted a python product from the Products directory and when
I start Zope the product is still listed in the Product list.  I then packed
the ZODB, cleared my Browser's cache, and refreshed the Product List but
still the product is visible.  I can however delete the python product
(which is by the way not in my Products directory) from the Control Panel.

Somewhere something is cached and I don't know where.  It seems to cache
errors as well and they stick.  A reinstallation fixed this problem, but now
it seems more fundamental.  I've come accross this odd caching behaviour
again after reinstall and can't reinstall every time this happens.

I run Zope 2.2.2 behind Apache 1.3.9 and do virtualhosting with the
ProxyPass directive.

Please help!!

IIRC, this stuff got broken by the switch to the new security machinery.
ZopeSecurityPolicy doesn't check 'foo__roles__' on the parent object the
way ZPublisher does/did.

Re: [Zope-dev] ZODB

2000-10-04 Thread Lalo Martins

For the third time, I have a similar problem. I deleted a
ZClass-based Product, but the objects of those ZClasses still
work - except for not having an icon or constructor, so I'm not
able to create or cut/copy/paste them.

Then, when I tried to import the newer version of the Product,
Zope gave me "Duplicate class Id", which means the old classes
still exist somewhere in its Dream realm.

This is on Zope 2.2.1. I'd really appreciate some clues on how
to bust these ghosts.

[Zope-dev] Zope 2.2.2 Issue: AttributeError: __call__

2000-10-04 Thread knight

I hope I haven't overlooked anything here, and not posting ignorantly.

After installing a fresh copy of Zope 2.2.2 on Python 1.5.2, everything
seems to look ok. I created a new user with Manager, and then proceeded to
create a subfolder for a new web site to test out some things in 2.2.2. I
created some dtml documents, then I connected with ftp to create a few
more dtml documents, and a couple subfolders with docs. All dtml docs in
the main subfolder were renderable. ANY dtml docs in subfolders below that
were _not_ renderable, and spit an AttributeError: __call__ generally
inside the standard_html_header. However, thinking that there was
something wrong rendering my header, I realized there was nothing
technically wrong with the dtml in the header.

After installing some products, they all ended up complaining about the
same thing.

I have confirmed this issue with the latest checkout of Zope2 from cvs.

Can anyone else confirm this as an issue?

Hi Jim!

Glad to here from you.  I don't think I'm clearly sharing the problem
I'm having.

See my comments below.

John Heintz

Jim Fulton wrote:
 
 "John D.Heintz" wrote:
 
  Hi all,
 
  I am about to embark on integrating ZODB with CORBA,
 
 Woo hoo!
 
  and am in the deep
  thinking phase of the endeavor.  ;-)
 
  What I want to do is _explicitly_ manage connections and transactions
  without being able to depend on what thread is running.  I know that
  this is _not_ the way that Zope works,
 
 That depends on your point of view.  The Zope publisher (ORB) largely
 automates transaction management for application programmers, so they
 don't have to deal with identifying transaction boundaries. So,
 from an application point of voew, these details are hidden.

First issue I need to clarify: I am not integrating ZPublisher, just
ZODB expose objects.  I want to do this because we are using ZODB to
persist complicated Python object (great database!) but are not
publishing them to the web.

 
 From a system point of view, Zope does manage per-thread transaction data.
 This is something a CORBA interface could provide as well.

CORBA provides two threading policies, and either could be used in a
thread/Connection per request model.  I am not intending on doing
Connection per request, I would rather manage Connections as longer
running activities so that I don't have to create servants more often
than necessary.

 
 IMPORTANT NOTE: The ZODB-provided transaction manager automatically
 manages per-thread transaction information.
 
 Were you aware of this? This sounds like what you need.

Yes, I'm pretty aware of this.  I have even studied the cPersistence.c
code, specifically the changed() function that calls the global
get_transaction() python function.
 
  but if I want to use standard
  CORBA I think I have only two choices:
  1) Explicitly associate Connections with Transactions in my CORBA
  layer.  What I need to do is allow any thread to change a Persistent
  object from some Connection,
 
 This would be nice. Basically, you want to open a ZODB database
 connection and begin a transaction at the beginning of the request.
 At the end of the request, you want to commit or abort the transaction,
 depending on whether an error occurred, and close the connection.

This is the Zope publisher model.  I want to rather keep a persistent
reference to objects in the Database (from a Connection) across CORBA
Requests.  This is the core reason that I am trying to manage
Transactions/threads/Connections explicitly.
 
  and make sure that the right transaction is
  called for "register".
 
 If I understand your requirements, then the standard transaction
 machinery should do this for you.

Except that I'm not committing or aborting necessarily at the end of a
CORBA Request.  I plan on having users login to the server and get back
a Session object that provides access to other objects in the system. 
That returned Session object will have a ZODB Connection and a
Transaction cached.  It also will expose through CORBA a commit() and
abort() method that delegates to the ZODB Transaction.

All this because I want to keep object from the ZODB Connection cache
around for a while.
 
  2) Build a complete wrapping adapter layer that does thread
  synchronization to the actual Persistent objects and proper thread for
  the transaction.
  - Lots of overhead and redundant coding - tricks with ExtensionClass
  might make this adaptation simpler to code, but still it won't be easy.
 
 I'm not sure what this is, but I think it probably isn't necessary.

This layer would exist to ensure that, across CORBA Requests, the
correct thread would be running.  The correct thread is the one that was
created in the CORBA Session object that open()ed the ZODB Connection.
 
  Obviously number one is my preferred choice.  In order to accomplish
  that, I see only two ways:
  1) Modify ZODB to maintain a Connection to Transaction link, and modify
  cPersistence.c to use that link in the changed() function instead of
  relying on the standard get_transaction() thread index.
 
 Is there a one-to-one relation between threads and connections
 (or, more precisely, is it the case that there is never more than
 one simultaneous connection per thread)? If so, then get_transaction()
 should do the right thing.

There would not be any predictable mapping from threads to connections
for any two CORBA Requests if I don't throw away the connections after a
commit() or abort().
 
  2) Replace the get_transaction() in globals to return the appropriate
  Transaction regardless of thread.
 
 It currently returns a different transaction depending on the thread.

In the CORBA exposure I would never call get_transaction().  I would use
the reference to a transaction from the CORBA Session object that
originally open()ed a database connection.
 
  Again, my preference is number one.  After going over the ZODB code, I
  _think_ that a Connection is always 

[Zope-dev] Trying to catch up - what are the best Zope tools today?

2000-10-04 Thread Itai Tavor

Hi,

I've been out of the Zope world for a few months... now I'm back and 
I need to quickly write a small-scale e-commerce application. It's 
got enough peculiarities to make it impossible to do with eTailer or 
EMarket, so I'm trying to figure out the best tools and approach to 
use for writing it, but so much has changed in Zope since I last 
worked with it. There's ZPatterns, LoginManager instead of 
GenericUserFolder, new session management products... the new tools 
seem much better than the old, but most are in development and carry 
dire warnings, and at least some of the old tools don't work in Zope 
2.2.

Can anyone provide a quick rundown of the best choices for building a 
production site at this time? I'm going to need sessions, user 
registration and login, and the usual array of e-commerce pieces 
(products, carts, orders, payments...), with all data stored in SQL.

I started reading about ZPatterns but I still can't get my head 
around it... I'm wondering if I should try to learn it fast enough 
for this project, or stick to what I already know. What in people's 
experience is the typical learning curve for ZPatterns? How much am I 
going to have to figure out to be able to build support for SQL 
storage? I couldn't find any examples for SQL use in ZPatterns - did 
I miss anything?

Thanks in advance for any comments.

catalog dataskins.. so I just set it to be an unconditional 'true'.

This way we didn't even to use property sheets. Basically the
skinscript could map the properties (and methods) that already existed
in the 'online catalog' onto properties of my 'virtual dataskins' so
that my app didn't need to be changed at all.

This was also nice since in my Specialist I could do things
like:

dtml-call "RESPONSE.redirect(this().theRealThing.absolute_url())"

After the user is finished working in my 'app area' they could
get redirected back to the actual object that my Specialist
was 'posing' for...

Re: [Zope-dev] ZPatterns design questions

 Ty and I use ZClasses because you can see your changes much more quickly
 than if you have to restart Zope.  Basing your ZClasses on DataSkin makes
 the limitations pretty much disappear, from our point of view, because we
 never put any actual "implementation" code in our ZClasses: just domain
 logic, property sheets and UI (DTML) methods.  All the actual mapping
 to/from data storage is carried out in the appropriate Rack or Specialist,
 neatly seperated.  Occasionally we need an ExternalMethod in either the
 ZClass or the Specialist, but these are getting rarer as we find ways to
 create method-like helper objects that can be added through the Zope UI to
 accomplish common tasks.  In general, we prefer that Python written outside
 of PythonMethods be re-usable for a variety of projects rather than a
 one-up for a specific application.  YMMV.  :)

While I wouldn't say that there has been an actual 'paradigm
shift' between the original RIPP presentation and ZPatterns,
I'm sufficiently confused at this point to ask for an
explanation (with definitions and a *simple* example) of
your current thoughts on separating 'domain code' from
'implementation code', both of which still need to be
separated from 'presentation code' (DTML interfaces), unless
I'm mistaken. Please assume I'm asking a lot of 'why'
questions along the way.

I'm familiar with the convention of separating 'data' from
'business logic' from 'presentation logic', but this new
four-way separation (storage, domain, implementation, UI) is
confusing the heck out of me.

I know that both of you (Phillip and Ty)  are very busy
right now, but could you perhaps give us a few short
installments? Starting at the beginning (wherever that is),
of course.

Thanks,

As far as user registration and logins, LoginManager in

The current membership product has not yet been

 Sadly, I think MailHost doesn't scale too well :-(
 
 What it'd need to do if you're sending the mail to a few thousand people
 is to be non-blocking.
 IIRC, currently, a method/page with a dtml-in
 addressessendmail/dtml-in tag pair in it will only return when the
 mail has been sent to all the recipients. So, if the mails going to lots
 of people, the page takes ages to return.

Perhaps it would be better to solve this by configuring your sendmail 
(or other SMTP MTA) to be non-blocking, i.e. store-and-forward.

Also you could send just one message to all the recipients instead of 
sending individual messages.

 This is the problem I had where our mail server was taking lots of time
 to send messages (it was doing lots of stuff to make sure the address
 was valid) so submitting posts on Squishdot.org was taking ages too.
 
 What, IMHO, is really needed is a mailhost/sendmail tag type thing that
 gets a message and a list of addresses to send it to. If it could do
 that in a seperate thread/process/whatever so that whatever calls it
 doesn't block, that'd be great. Of course, it'd need to have a 'hook
 back' method provided so any errors that occured could be dealt with.

 I wonder how mailman does this stuff and if the code could be borrowed
 for Zope?

Maybe you could just use mailman as MTA, greating temporary
mailing-lists.

[Zope] SiteRoot

2000-10-04 Thread Stephan Goeldi

I have a problem with SiteAccess:

My site runs with Apache and Zope 2.0.0.
Apache has 2 Domains:

www.domain1.com
ProxyPass to Zope:
http://123.123.123.123:8080/provider/www/domain1.com/
in Zope exists:
/provider/www/domain1.com

www.domain2.com
ProxyPass to Zope:
http://123.123.123.123:8080/provider/www/domain2.com/
in Zope exists:
/provider/www/domain2.com

In both subdirectories (domain1.com and domain2.com) exist the SiteRoot 
method. In the SiteRoot method is written:
Title: www.domain1.com
Base:  http://www.domain1.com
Path:  /

When I point my Browser to www.domain1.com everything works ok.

Now I create /provider/www/domain2.com
OK
I create the acl_user domain2.com with a password.
OK
I create a SiteRoot:
Title: www.domain2.com
Base:  http://www.domain2.com
path:  /
OK

I restart Zope and Apache
OK

Now when I point my Browser to www.domain2.com I get the Website of 
www.domain1.com. I go to http://www.domain2.com/manage and get the folder:
/provider/www/domain1.com instead of /provider/www/domain2.com

When I log in as domain1.com I get the folder
/provider/www/domain1.com and everything works ok. But I can go up to the 
folder
/provider/www and see what else is in this folder. But domain1.com has no 
access to this folder, i.e. there is no acl_user in this folder.

What goes wrong?

I already tried to upgrade to 2.2.1 and 2.2.2 but this destroys the data 
structure.

Any suggestions?

[Zope] Last-modified header missing -- time-stamps turned off.

2000-10-04 Thread Jean Jordaan

Hi all

Just a note from the blue .. I'm snarfing the ZB using 
  wget -np -m http://www.zope.org/Members/michel/ZB/
and for every document I'm seeing:

  Last-modified header missing -- time-stamps turned off.

What's the significance of this? I assume something to
do with the http headers returned by Zope. Does Zope not
include last-modified headers since it predominantly serves

yes, the python versions I use are compiled for threads, they link

it does not work for me yet - it shows in Zope as broken product.
I also spoke to local Oracle hotline and they said that ODBC access is
not thread safe until 8.1.6.1.1 due to some error in OCI libs. Now I am

If Python is compiled without threads, there is no module
"thread". Zope relies on this module. It dies immediately,
if it is not there. Thus, you can be sure, your
Python has thread support compiled in.

  So, does anybody know of either binary and threaded Zope driver for
  Oracle , Sybase etc. or the same ODBC driver? And what is the state
of
  python threading on WinNT paltform?
The Python that comes with Zope has thread support compiled in.

Maybe, your Python-ODBC connection "forgets" to release
Python's interpreter lock.

We, once, had such a problem.
   Accidentally, the DCOracle module had been set up with a standard
   Python distribution (with threading disabled) rather
   than the Zope Python. As a consequence, the
   DCOracle did not call "releaseLock" and
   "acquireLock" (as they would not be present
   in a non-threaded Python).
   And, of course, database operations blocked Zope.

Is it possible, that you upgraded from an earlier Zope installation?

The traceback suggests that your requests tries to access
the object "broken", probably an object from a broken
product.

Thanks, I've found the problem: It was a broken ZPatterns. I've updated to
0.4.2a3, but left an "old" compiled Dynpersist.so in the directory (V 0.3).
After updating this, everything was fine. I guess I just have to be prepared
to get the weirdest sstuff to see as long as I 1.) use alpha/beta products
to authenticate my users on root level, and 2.) keep refusing to wear
glasses (Actually, this beta ZPatterns is fine).

I suggest, you start Zope with "STUPID_LOG_FILE=zope.log".
This should log problems during Zope startup to
"zope.log" (you may need to upgrade to Zope 2.2.2, as
earlier Zope versions lost one exception log due to a missing

If you see no problems logged, try to go to

 objects. Coming round to cleanup time and I wanted to remove certain
 visible functions from the default object views unless you have already
 logged in (with various possible roles)
 
 in the index_html of my zclass i have
 
 dtml-if "AUTHENTICATED_USER.has_role('Staff')"
 a href="dtml-var absolute_url/dtml-var typeedit"edit this/ahr
 /dtml-if
 so if the user is anonymous or logged in without the Staff role assigne
 they should not see the "edit this" link ...
 
 Doesn't work! It basically never returns a 'true' response thus never
 displays the edit this link even when logged in.



try (untested)

dtml-if "AUTHENTICATED_USER.has_role('Staff')==1"

or (tested)

dtml-if "'Staff' in AUTHENTICATED_USER.getRoles()"


Cheers

Kapil

[Zope] Implementing a distributing mirror

2000-10-04 Thread Luciano Caroti

Hi,
I would like to implement a system to distribute PDF document. I would like
to use ZOPE on 5 server distributed in Europe. I would like to build a
system that send an email to a paying user where I put an URL. I would like
that in URL I send temporary authentication information to allow access to a
virtual directory where I put only documents or images files that user
purchased. Have you any hints on how implement this architecture?
Thank you in advance,
Luciano Caroti.

[Zope] help! dtml-if question

2000-10-04 Thread Dr. Anthony Monta

Hi,

I've tried to find a solution myself but now am stuck.  I created a little 
"Blurb" product for a university department website so that faculty members 
can announce recent publications on the department's homepage.  They create 
these ZClass instances in their own folders, and a DTML method in the 
top-level folder grabs and displays them at random.  (I want to avoid using 
ZCatalog for the time being.)  What the method does is randomly choose a 
faculty folder, and then randomly choose a Blurb instance within that 
folder.  Here's the hack I came up with:

dtml-with Dept
  dtml-with Fac
   dtml-with Sites
dtml-with "_.whrandom.choice(objectValues(['Folder']))"
 dtml-with "_.whrandom.choice(objectValues(['Blurb']))"
  dtml-var index_html

(end tags omitted)

The problem is that this method will produce an Index Error when it comes 
across a folder that doesn't contain an instance of "Blurb" class.  So I 
need to make the selection of a folder conditional on Zope's finding a 
Blurb in that folder.  Here's what I tried after reading up:

dtml-with Dept
  dtml-with Fac
   dtml-with Sites
dtml-with "_.whrandom.choice(objectValues(['Folder']))"
 dtml-if "_.has_key('Blurb')"
  dtml-with "_.whrandom.choice(objectValues(['Blurb']))"
   dtml-var index_html
/dtml-with
 dtml-else
  Some default Blurb would appear.

This method fails.  Can someone help?

Cheers,
Anthony

On Wed, 4 Oct 2000, Hannu Krosing wrote:

 Perhaps it would be better to solve this by configuring your sendmail 
 (or other SMTP MTA) to be non-blocking, i.e. store-and-forward.

This seems like a good idea.  It makes it hard to get disposition status
for the delivery in the transaction - but that problem is intrinsic to
email communications, and probably best addressed by using the "sender"
header (i think it is), so delivery failure notifications go to someone
who needs to know about the failure.

Even better - but lots more complicated: have the failure notifications
directed to a program which queues the fact of the failure for the sending
program to use.  I haven't used it, but contemporary MTAs have catchall
aliases, by which you can handle a pattern of recipients.  Have the
envelope sender fit the pattern, and encode the information about the
program that needs to get back the failure information.

I think this kind of architecture is necessary for comprehensive mail
sending from zope, with delivery failure accounting, since mail sending is
inherently asynchronous.

 Maybe you could just use mailman as MTA, greating temporary
 mailing-lists.

This is also a good idea in principle, but would wind up being cumbersome.  
Mailling list "objects" are heavy weight components in mailman - each one
having a list metadata and archive directory, mta aliases, etc.  Plus, you
may have to leave the list up until the last delivery is completed
(successful or not).  Better, i think, to adopt techniques and steal code
from mailman, to take the pieces you want.  Ultimately, i don't think
you'd be taking that much - there's a lot in python that gets you a lot of
the way.  It's the embedded knowledge that's useful...

i'm having a strange problem with cookie based user authentication with 
ms internet explorer 5.5 on windows. it seems that the browser (but only
this version and only under windows!) seems to "forget" its cookies, which
results in an immediate logout. does anybody have similar experiences or a

Re: [Zope] IMAP and Zope!

2000-10-04 Thread Joachim Werner

Thanks for the input I got!

Just a small wrap-up of what I learned:

- The NotMail and old IMAP Adapter code don't seem to be seriously used by
   anybody

- WorldPilot could be a solution, but it only if it was more modular. Ryan
   Hughes promised to integrate it into Zope by release 2 (incl. a ZODB-based
   document storage

- There is a similar project by Morten W. Petersen that also will feature a
   ZODB-based message storage that will be searchable, Catalog-aware etc.

Re: [Zope] help! dtml-if question

2000-10-04 Thread Jim Washington

Hi, Anthony

how about:

dtml-if "_.len(objectValues(['Blurb']))  0"

Your _.has_key() (I think you meant _.hasattr()) statement was looking 
for something named "Blurb", not a thing of type"Blurb", so of course it 
failed.

The objectValues(['atype']) statement returns a list of the things of 
the type,  so checking for a non-zero length of the list will do what 
you need.

web_client(url='http://someserver.com', timeout=60)
or some variants of it.

(or it doesnt work at all for some other reasons.)

 colours are not supported by all browsers, or are not interpreted the
  same.

 No, the problem is, that they are not displayed the same.


Not long after posting my message I realised this also. (o8

 Zope, every once in a while, will just stall indefinitely. The Zope process
 doesn't die, it just hangs.

 Any thoughts. I've posed this question to a lot of people many times. Now
 that it's back, I'm hoping for fresh insight.

hm.  have you been using -M to see which things are being called when it
hangs?

 What's the significance of this? I assume something to
 do with the http headers returned by Zope. Does Zope not
 include last-modified headers since it predominantly serves
 dynamic pages?

This is correct. No Last-Modified headers except for files and images
(and that is specific to zope.org).

Including a last modified header isn't hard, however:

[Zope] WDDX anyone?

2000-10-04 Thread Albert Boulanger

Has anyone considered WDDX for Zope? This seems like a nice next step to

exchanging data beyond RSS, but not as ambitious as SOAP and has SDKs
for  CF, perl, etc.

I have some applications in mind for intranet syndication that goes
beyond what RSS can do. Also there is full rdf.

From: http://www.wddx.org/

Welcome to WDDX.ORG, the home of the WDDX SDK and related projects.
WDDX.ORG seeks to empower Web developers with technology that enables
them to create new forms of value on the Internet using distributed data
and Web syndicate networks. The Web Distributed Data Exchange, or WDDX,
is a free, open XML-based technology that allows Web applications
created with any platform to easily exchange data with one another over
the Web. To learn more about WDDX, check out the Understanding WDDX
section of the site.

Who created WDDX?
Allaire created WDDX in order to solve key problems in exchanging data
between Web applications. In particular, Simeon Simeonov, Allaire's
language technology architect, created WDDX to support problems of
distributed computing within ColdFusion. This work was generalized into
a cross-language framework, and resulted in the creation of the WDDX SDK
and WDDX.org. The WDDX SDK was created by Nate Weiss, an independent Web
developer, with the support of Allaire and a number of other third
parties.

How does WDDX work?
All of the standard programming environments on the Web (ColdFusion,
Perl, ASP, Java, JavaScript, PHP, etc) include native data structures
such as arrays, record sets or value pairs. WDDX provides a module for
each language that will automatically serialize or translate the native
data structures into an abstract representation in XML, or deserialize
WDDX XML into a native data structure. For example, you could use WDDX
to take a complex array in ColdFusion, serialize it into XML, send it to
an ASP server, and then deserialize from XML into a VBScript array
object with all the types natively converted. This conversion process
between languages is relatively transparent to developers by shifting
any XML processing and interaction into the WDDX modules, eliminating
developers from having to directly program or manipulate XML themselves,

This is not an RMI mechanism.

Albert Boulanger

[Zope] Hotfix_2000-10-02 - fails with GUF and zope 2.2.2

2000-10-04 Thread Andrews, Martin

When I have the 2000-10-02 hotfix installed I can no longer authenticate to
zope. I fails with the attached message (Error Type: AttributeError, Error
Value: editabsolute_url). I am guessing the problem is related to the fact
that I am using GUF 1.2.4 (patched to have the getUserById() method). Any
ideas?

You need to select *Use Database Methods* on your ZClasses *Permissions*

I haven't really groked why it's that hard, but it works.

So what about this couldn't be emulated with xml-rpc?

[Zope] LDAP won't work - yes I've applied the patch

True.. But, well, its the other end. The SDK available at www.wddx.org
is a path towards exchanging data with other well known systems such
as ASP and CF. I found out that the PYTHON XML package does include
WDDX serialization... cool.
