[Zope-dev] RFC: page contracts

2000-08-30 Thread Petru Paler

Hi eveyone.

While playing around with the development version of ACS (ArsDigita Community
System), I noticed a very nice feature they introduced, namely page contracts.

In ACS, this means that every tcl page starts with a call to ad_page_contract.
In the parameters passed, you specify:
   - general page documentation (what it does)
   - author(s)
   - creation date (not needed for Zope since we have bobobase_modification_time)
   - CVS ID (not quite applicable for Zope (yet?))
   - the expected input variables (from forms) along with their default values
   (where applicable) and types (having a couple of types like "integer" and "string"
   predefined and an easy-to-use plugin system to add custom types)
   - an optional validation block in which you can check the input data ranges
   and validity (you can also make validation rules depend on each other so if
   one fails, the rules which depend on it aren't tried)
   - an optional custom error messages section (to use when one of the required
   input variables is not there or does not match the format, or when a validation
   block fails). If you don't provide this some reasonable defaults are provided.

IMHO, such a feature would be very useful for Zope too. I find myself quite 
often doing input validation and error handling in DTML, which is (to say the
least) painful.

I would be interested to give a try at implementing this, but before starting
I wanted to hear community's opinion on:
   - whether this would be useful
   - how this should be aproached (the two possibilities I have in mind until
   now are either a separate manage tab for the page contract, and there a
   HTML-based interface for building it, either a dtml-contract tag which
   surrounds the page contract (written in python probably) and placed at the
   top of DTML documents/methods).

[Zope-dev] generic login

Hi,

We are developing a generic site login package based around a mysql 
database. Instead of reinventing the wheel has anyone done this before 
specifically using mysql.

Cheers,

[Zope-dev] dtml-tree question is buggy! surprise! ;-)

 Why is this trying to append to 's' when 's' has become a tupple somewhere
 before this line???... tupples don't accept append!!

Yup, I got this too when I tried to make a 'batched tree' by doing a
dtml-tree with the result of a dtml-in.
I gave up...

IMNSHO, dtml-tree needs a big rewrite.

I'd love to do it, but two things are stopping me:

1. Other projects (Swishdot leaps out ;-)

2. As everyone knows what I think already: DTML has 'some problems'. In
the course of solving these, I hope the problems with the tree tag will
go away as a matter of course. that means fixing it now would be a waste
of time ;-)

I dunno, is anything being done to solve the 'DTML problem'?
(there seem to have been a few proposals on dev to help, how are they
getting on?)

Zopistas,

I'd like to point out the new proposal at:

Re: [Zope-dev] ZPatterns bug: Customizers don't rename well

2000-08-30 Thread Phillip J. Eby

At 07:32 PM 8/29/00 +0100, Steve Alexander wrote:

To reproduce the error, do this:

  Create a Folder with Customizer support
  Give it a Customizer
  Rename that Customizer
  Press the "Customizers" tab in the folder

Zope Error

Error Type: AttributeError
Error Value: __customizerRegistry__

What's happening is that the new manage_renameObjects (plural) function
doesn't have a masking method in PlugInGroup.  These masking methods serve
to alter the URL base used for the management tabs, so that a PlugInGroup's
management tabs will point to the parent PlugInContainer's methods, and not
to nonexistent methods of itself.  The resulting error is a harmless side
effect of this URL confusion; you can simply click your way back into the
right place and everything will work fine.

Meanwhile, I'm adding the following method to the PlugInGroup class for the
next release of ZPatterns:

def manage_renameObjects(self, ids, new_ids, REQUEST=None):
"""Rename several sub-objects"""
self.aq_inner.aq_parent.manage_renameObjects(id,new_ids)
if REQUEST is not None:
return self.manage_main(self, REQUEST, update_menu=1,
URL=REQUEST.URL1+'/manage_workspace')

This should fix the problem, although I have not yet tested that it in fact
does so.

Re: [Zope-dev] ZPatterns bug: Compute instance has not _objectAdding method

Zope 2.2.1, ZPatterns 0-4-1snap1, with some small patches.

I'm adding a dataskin-derived ZClass instance underneath a Customizer

The Customizer has a SkinScript plug-in.

When I try to add a new ZClass instance, I get an exception that I can
trace to the fact that DataManager's _objectAdding method is trying to
call _objectAdding on a Compute object.


I actually fixed this problem about three weeks ago, but neglected to
publish the code.  :(  In the latest version, all of the objects which the
SkinScript compiler creates are derived from a class "NullProvider" which
has empty methods for all the _objectXing events, including _objectChanging.

Luckily, there is not much more to do for the new release (0.4.2b1) besides
updating the release-related files, and perhaps a bit more work on
improving the management screens for SkinScript methods.

[Zope-dev] 2.2.1 changes tighten security?

2000-08-30 Thread Bill Anderson


Working on a new release of Membership, I have encountered a problem.

Doing the development in 2.2.1, I cant seem to access my roles managemenu UI as 
Manager.

For those who haven't seen it, her eit is:
dtml-in ShowUsers
  dtml-call "REQUEST.set('user',_['sequence-item'][0])"
  form action="/acl_users/manageRolesForUser" method=POST
   br dtml-var user dtml-var "user.roles"
   input type=hidden name=user value="dtml-var user"
   input type=submit name=submit value="Manage Roles"
  /form
/dtml-in
Where ShowUsers is a python mehtod that returns a list of user objects.

The traceback indictaes the problem lies in accessing "user.roles". roles is on the 
Restricted Property sheet, which
requires you have the 'Manage users" role. Of course, as manager, I expect I have it. 
:)

This worked fine in 2.2.0, and was wondering if anyone knew what changes would bring 
this behaviour out, and how to fix
it off hand.

TIA, Bill

Re: [Zope] getting parent document

2000-08-30 Thread Anders Holmbech Nielsen

Thanks for your answer. This would do too, but Stephan Richter gave 
me a nice way to do it. A dtml-method with the following:

dtml-raw

Because of acquisition this will result in the "document" being 
included in its whole.

His suggestions:

1.
html: contains the HTML code
viewMethod:  called like: viewMethod?file=html
dtml-var "_[file]"

2. The best by far. Write your own little Zope object in Python that 
has only an id and a body.
Then you can say: URL/html/viewMethods
Inside viewMethods: dtml-var body

3. Well, I found solution 3 reading the DTML Method source code pretty quick.
inside viewMethod:
dtml-var raw  -- That returns the unprocessed body of the object 
and due to the acquisition behavior of DTML methods it looks one 
object up, which is html. so URL/html/viewMethod works


Anders Holmbech Nielsen writes:
   I have a dtml-method called test which I want to use like:
  
   someurl/document/test
  
   and in the dtml-method I want to include the document in its whole.
  
   I have tried something with the URL like:
  
   dtml-var dtml-var URL1 this offcourse dont work... but this neither...
Try:

   dtml-var "PARENTS[0](_.None,_)"

"PARENTS[0]" gives you the parent, in your case "someurl/document".
Calling this object renders it.
If you call it without parameters, you cut the namespace chain.
If you pass "_.None,_", you pass the namespace explicitly.
(This usually is done by DTML behind the scenes, but
inside "...", you must do it yourself).

[Zope] GUF and manage_addGenericUserFolder not working

2000-08-30 Thread Jason Byron

I try to call the function manage_addGenericUserFolder
in a DTML Method but I keep getting a NameError for
it. It's as if Zope can't find the definition.

I'm stumped as to why it won't work in DTML.
- The product is installed and not broken.
- I can add GUF's under the management screen with
'Add' and everything works fine.
- I've tried to make the call with all of the possible
parameters but nothing helps.
- manage_addUserFolder works fine.

Has anyone else had this problem?

I just upgraded to Zope 2.2.1 and I haven't tried an
older release.  Do you think this might have to do
with the changes to the security model in 2.2.1? 
Should I use manage_clone instead?

Thanks for any help, 
Jason

Re: [Zope] ZCatalog in 2.2.x

2000-08-30 Thread Terry Kerr

I am not searching from a form in that sense...I am talking about at the python
level.

I have self.searchResults({'description':'blah'})  where description is meta
data in the catalog and a textindex and 'blah' is in the Vocabulary.  This
previously worked in zope2.1.6.  Now in 2.2.0 and 2.2.1 it doesn't work.  The
only thing way I can get searchResults() to return a non empty list is to search
using a Field index and a valid string to match with.

 Terry Kerr [EMAIL PROTECTED] said:

  Hi,
 
  I have a python product which uses a ZCatalog and CatalogAware
  products.  The catalog has a number of Field and TextIndex indexes.
  Search the ZCatalog has worked fine when my product is instantiated in
  2.1.6.  But now when I instantiate my product in 2.2.0 or 2.2.1,
  searching only works when I search using a field index.  Searching using
  a textindex always results in an empty result, even tho I can see the
  words I am searching for in the Vocabulary!  Any suggestions?  I have
  tried reindexing, completey recreating the Zcatalog, recreating the
  Vobulary and reindexing, and nothing has changed the behaviour.  Are
  textindexes simply broken?
 
 
  ZCatalog seems very volatile to me!  Every time I have upgraded way back
  from zope2.1.3, something in zcatalog has changed and boken my product.
  So far I have managed to find fixes, but this one has got me baffled!!
 

 My experience has been that if field indexes are unspecified, the catalog
 will only match where those fields are empty.  In other words, by not
 specifing anything for the field indexes, you are actually specifying that
 for a match, they need to be empty.
 To get around this, I put another method between the form for entering what
 you wish to search for, and the method that actually searches the form.  This
 method looks at the field indexes, and if nothing has been specified, it
 doesn't pass them on to the method that does the actual search.
 An alternative to this, is to use names for the field indexes that aren't in
 the catalog index, and then at the start of the search method, check those
 names, and if they have a value associated with them, add to REQUEST what the
 names in the index are with the appropriate values.

 There may be a better way, I'm still pretty new to Zope and DTML sort of
 stuff.

Re: [Zope] SSL and PGP

Sounds interesting, I ve checked out M2Crypto

it patches Medusa and ZServer in order to handle HTTPS,
so Zope itself becomes a SSL enabled server without needing
a proxy or gateway.

But modifications to Zope's core 
components such as Medusa seem risky to me as
long as Digital Creations don't integrate them into the
official release, because every update to a new Zope release
can become a horror trip when the SSL patches clash with

Are there any plans by DC to do something in that matter?

The way I'm reading this, you have this entire database of albums and

Don't do that.

Refactor your product to use subobjects of your Jukebox object as 
albums, and subobjects of those as tracks.

Then, only a small amount of data gets rewritten on each transaction.

[Zope] Z Database Connections - pass uid/pwd to RDB

2000-08-30 Thread Philipp Auersperg



When you create a Z database connection you must supply a fixed 
connection
string with a fixed uid/pwd to open that connection.

So every user that connects to Zope connects with the fixed uid/pwd to the 
relational database.

Is there any way or workaround to dynamically pass the Zope uid/password to 
the relational database?
This is important when user security is maintained by the database 
scheme.

Not that I really want this feature for my use but we have projects where 
the customer has the database model
ready and wants the users to be individually authenticated at the 
relational database (in this case: Oracle).

 zope's logs are in a pretty standard format so most of your loganalyzers

 certain ips or urls.

Of course.  I'm actually parsing Apache logs on my own site, as this
covers both the Zope and non-Zope portions of my page.  The basic
analysis isn't Zope-specific, just more Zope-accessible.  For
instance, hits are returned as a list of page/count pairs, and then
you can format then as you wish with DTML.

Any of these things that I've done could be done by other log
analyzers, and I expect they have been.  They could probably be done
better: the real advantage of what I'm doing (in my own experience) is 
that I have a fair amount of control to do whatever I want, not just
what was included in the software.  Anyone who knows some Python would
be able to have a similar amount of control.

 i've been told that http://www.webalizer.org/ is pretty nice.
 
 a zope web logs analyzer that makes images with PIL integrated into the
 control panel, is on my list of things to do although its pretty low at
 the moment.

I hadn't been thinking of using PIL myself -- though it would be
relatively easy, I suppose, to add another layer that creates graphs

[Zope] Management Interface Refactoring?

 This means, you want to look at the source of "manage_delObjects"

 You will see, that it contains:

 Thus, do not pass it a REQUEST.

It's this kindof hackiness which I really hope MJ's work eventually gets

A simple but effective approach would be to split up every manage_*
method into two methods:

- manage_do_* does the work.
- manage_* calls manage_do_* then returns HTML.

Perhaps this could be added to the "clean up the core" proposal.

Well, with cookies, it's simple: delete the cookie. I think most fo the

on zope.org)

With Basic Auth it's a bit tricky. Basic Auth really only works 'cos

request a new page that it thinks those details apply to. So you just
have to persuade the browser to stop cachign that info ;-)

I think you can do something like:

dtml-raise Unauthorized

which works on most of the browsers around. I don't know though, maybe I
got the syntax wrong :S

Re: [Zope] Generic Workflow Products?

2000-08-30 Thread albert boulanger



   i haven't had time to read through the links, although i will once i get
   some more of that mystical free time stuff, but i wanted to clarify
   about PTK workflows. most of the existing workflow structs in PTK were
   doc based with simple workflows, but there has been a concerted effort
   to refactor PTK into Singleton objects which give abilities to all
   objects vs. the old method of inheritance for abilities. In this
   scenario workflow objects can be plugged into the architecture. Another
   item that gives support for complex workflows is the
   event/subscriber/publisher system being developed right now. check out
   the later half of the PTK archives for August to get some more
   background. if you want to influence the project, now is the time, make
   your voice/needs heard.

One place to start would be to have a look at
openflow.sourceforge.net. This Zope based workflow system is based on
WFMC's reference model. It does not have everything you would want but it
is a good start. Once reason to be looking a WFMC is that such an
implementation would allow integration with existing workflow systems
such as Staffware's. SWAP and the newer WFMC XML wrapping would also
be worth considering as they would be like XML-RPC for workflow which
would enhance interoperability. There is a need to execute a workflow
box which would exec a app associated with the box on data -- this
data not being just one doc in a members PTK folder but a suite of
data for the step.

There is opportunity for a Zope based system to be the web publishing
side of existing workflow systems, like Staffware's. Staffware's white
paper on how they will do web-based workflow begged for a solution like
Zope.

Staffware is one of the better workflow systems that includes the
ability to execute programs within workflow.

Certainly for usecase analysis one could look at existing packages
like Staffware.

For events, one might consider adopting some of the "webwise" event
system standards coming out. I have not followed these closely, but I
know they exist. One reason to do so is that this would enhance
interoperability with external packages that also adopt standards.

Albert Boulanger

 Well, with cookies, it's simple: delete the cookie.

   You cannot just delete the cookie 'cuase Zope is server, but cookies are

  My experience has been that if field indexes are 
 unspecified, the catalog
  will only match where those fields are empty.  In other 
 words, by not
  specifing anything for the field indexes, you are actually 
 specifying that
  for a match, they need to be empty.
  To get around this, I put another method between the form 
 for entering what
  you wish to search for, and the method that actually 
 searches the form.  This
  method looks at the field indexes, and if nothing has been 
 specified, it
  doesn't pass them on to the method that does the actual search.
  An alternative to this, is to use names for the field 
 indexes that aren't in
  the catalog index, and then at the start of the search 
 method, check those
  names, and if they have a value associated with them, add 
 to REQUEST what the
  names in the index are with the appropriate values.
 
  There may be a better way, I'm still pretty new to Zope and 
 DTML sort of
  stuff.

 Can you be more specific?

Andy can fill you in on the specifics.

  What's insufficient about the current
 implementation?

It doesn't scale well, especially for things where you have lots of new
data arriving (this is the BTree problem, I think...)

It has no published and well defined query syntax (there's patches here,
bits there, but no definitive document on how to use it, how to batch
with it, how to perform complex and structured queries, particularly
with TextIndex'es)

Don't get me wrong, it is very cool, but only kindof 70% there :S
(and I get the impression that doing the remaining 30% properly would
require a rewrite...)

As an example, we've been trying to do Zope-based versions of the
mailing list archives for a coupla months now and the Catalog keeps
exploding in different ways (huge resource consumption, even for only
30K messages or so, no matter what storage is used)

Then there's the ubiquitous 'KeyError's and other associated weirdness,
all of which leaves me feeling a lot less than totally confident in the
Catalog ;-)

comments very welcome,

Chris

RE: [Zope] Versions...

2000-08-30 Thread Chris McDonough

Versions are problematic in combination with mounted storages in
particular because there is no link in versioning between storages.  You
can easily create a versioned object in one storage, then traverse to
another part of the instance space that's been mounted and use that
version cookie to make a change.  But you need to commit the two
versions separately.  If you commit one of them, you'll be left
scratching your head as to why the other storage didn't commit.

I'd say in this particular that it's perhaps a limitation of mounted
storages rather than versions.

Yellow ppl,

ZMenu is a complete navigational system that uses a tree like display. It
allows you to dinamicly add a navigational link menus system to your site.

This ZClass based product is still in a development stage and I'dd like to
have some feedback about it... so email me about any problems or sugestions.

Re: [Zope] FSSession problems...

2000-08-30 Thread Hung Jung Lu

Curtis,

Could you describe how often does the problem happen? How many session users 
goes to the site? You mentioned about a month of public usage. During that 
month, did you have one single incident? How many sessions happened during 
that month?

All key-based session management systems are intrinsically unsafe, since 
other people can tap into your session, with non-zero probability, if the 
key-length is finite. The only hope is to make the key long enough, so even 
if the hacker has a supercomputer, it would still take him/her the age of 
the universe to crack into your website. One thing I mentioned to Pavlos 
(and/or Anthony Baxter?) before is that the key lengths of their cookies are 
a bit too short. For my HappySession product (another session management 
product, which is RAM based), I cranked up the key length to 128 
alphanumeric char key, exactly because I wanted no key collision for a long 
long time. :)

Another thing I observed during the development of HappySession was that on 
Linux (and Debian) server systems, I had problem with deleting the cookies 
of the clients. (No problem with NT server.) At the end, I chose not to 
delete cookies but instead setting their values to blank, when the session 
expires. It was a weird problem, I did not know why I couldn't delete client 
cookies (maybe it was a mistake on my part), but I chose the simple way out 
by setting the cookie to blank. And it worked fine. So instead of detecting 
the presence of the cookie alone, I detected the presence AND whether the 
cookie was blank.

regards,

Hung Jung

[Zope] Graphics served randomly. Apache - pcgi cacheing problem

2000-08-30 Thread Felipe E. Barousse Boué

Has anyone seen the following behavior:

I am using PCGI with Zope 2.1.6 and Apache 1.3.9. Everything works fine
except when reloading the same page, the graphics in it are not
"painted" by the client browser.

Checking on the apache logs, I found there is a 304, meaning the object
has not changed on the web server and therefore the client should be
using its local cached copy. On the Z2.log, for the same graphics
requests, there are no 304's but 200's meaning Zope DID serve the
graphic through pcgi. So, It  appears Apache is loosing the graphics
somewhere.

Nevertheless, the graphic is never rendered.  Weirdly this happens on IE
5.0, Netscape 4.75 and StarOffice 5.2. All browsers do have at least 5
MB of disk cache and 3 MB of memory cache. This confirms the problem
lies on Apache itself. Am I right?

This happens in a random fashion. I have not been able to establish some
pattern.

The text on the pages gets rendered fine.

Any ideas on how to solve this issue will be greatly appreciated,
Best regards.

Hi,

Not quite a horror trip, but yes, eyeballing the stuff all over 
is necessary.

Speaking as the developer of ZServerSSL, use Apache+SSL or 
Roxen+SSL for production. ;-)

ZServerSSL isn't working well with Zope 2.2.1 currently. I haven't
found out if it's due to changes in Zope 2.2.1, bugs introduced 
while evolving M2Crypto, changes in OpenSSL 0.9.5 versus 0.9.4, or 
the much faster CPUs I'm now developing on. Python 2.0 is yet another
variable in the equation. 

For your other requirement, ZSmime (also on my website) generates
S/MIME-signed/encrypted messages. In my HOWTO, I give an example 
of combining ZSmime's dtml-smime tag with dtml-sendmail to send
S/MIME messages. Netscape Messenger handles the S/MIME fine. So 
should Outlook, I imagine.

However, the Zope 2.2 change that Zope's superuser cannot do too
much means GuardedFile (a supporting product) is now probably broken.

I've been busy at work in the past months. I'm only now revisiting
this. Things should be fixed over the next fortnight or so.

Cheers.

Does GUF have an idle timeout setting?  I'm seeing the behavior where if my

If there is such a setting, how can I increase the amount of idle time?

   i haven't had time to read through the links, although i will once i get
   some more of that mystical free time stuff, but i wanted to clarify
   about PTK workflows. most of the existing workflow structs in PTK were
   doc based with simple workflows, but there has been a concerted effort
   to refactor PTK into Singleton objects which give abilities to all
   objects vs. the old method of inheritance for abilities. In this
   scenario workflow objects can be plugged into the architecture. Another
   item that gives support for complex workflows is the
   event/subscriber/publisher system being developed right now. check out
   the later half of the PTK archives for August to get some more
   background. if you want to influence the project, now is the time, make
   your voice/needs heard.


Here are two useful diagrams from WFMC's white
paper, "Workflow and Internet: Catalysts for Radical Change" (

[Zope] RE[3]: [Zope] Product inheritance question. == Pb. moving class from a product to another + etc.s from a product to another + etc.

2000-08-30 Thread NABETH Thierry
Title: RE[3]: [Zope] Product inheritance question.  ==  Pb. moving class from a product to another + etc.





Hello,


 If it is a class method, it must be inherited by any derived
class.


This is what I had done.



However, I had the time finally to conduce the following tests.
- create a Product P1 
 (Note: I used the word package instead of Product in my previous postings)
- create a Class A in P1
- create a method z in the Class A
- create a Product P2
- create a Class AA that inherits A in product P2.
- create an object 'o' instance of Class AA.
- make the test of calling the method z on 'o'.


Results: everything works fine !!
So everything seems to work correctly with the new version.


However, when I try to do the same (create a method z and test) for Packages
that I had created in the previous version of Zope, it just does not work !!
(I have imported in the new version the class I had created in the previous
version).


I believe that this had to do with the trick I used to split and existing Product
in several Products: Since I could not move a class directly from a package to another,
I created 2 copies of the same packages. I deleted from the first package the class I wanted
to move. From the second package, I deleted the classes I didn't want to move.
The result was 2 packages with each the correct set of classes.
The problem is that this seems to have generated some kind of inconsistancy,
in particular related to the namespace: the second package do not have access to
the namespace of the first package.


I know this was a relatively ugly way to proceed, but I found at that having
a zillion of classes in a same package was even more ugly, and I needed to reduce
this complexity by introducing more modularity.


Of course, at the beginning I couldn't predict which Products and which classes
would exist and I decided to start with one package and split it later.
If you had nor noticed I used some kind of incremental/prototypical/evolutionary/blablabla
methodology.


Unfortunatly, not being able -- to move classes from one product to another -- makes
the use of this methodology problematic :-(.


Another similar problem is that you can not modify a posteriori the inheritance tree.
(for instance when you decompose a class into 2 subclasses that inherit from one another).



To conclude, I find Zope to be a very interesting systems (because it is dynamic,
object-oriented, integrate seamlessly an OO database, etc.).
However, it would be an even better system if it provided more flexibility to
reengineer an architecture. (very important when you use a prototypical approach).


Or perhaps, there is something I have not understood ?

[Zope] ZClass and Propertysheets

2000-08-30 Thread Andy Pahne



Hi,

I have created a ZClass with a propertysheet called "Basic". I added a
property "db_id", integer value with a default value of 0. Then I created
two instances and changed the value to 1 in the first and 2 in the second
instance.

When I try to render the property with a dtml-var db_id I get a 1 in both
instances. That's not what I expected in the beginning. In particular not
because there doesn't seen to be anything wrong when I have a look at the
property sheet in the instance's management screen. I have different values
there.

Am I wrong or is there something wrong with Zope 2.2.1 and ZClasses?

I have asked the following question on the zope list, the squishdot site, and 
the squishdot eGroups site without a single response.  Is there something I 
am leaving out or is it a hard one?

Question:
I am running Zope 2.1.6 and Squishdot 6 (upgraded from 2-3-5-6). 
I have created a keyword search of my entire site. I see the Squishdot 
site listed as a cataloged object, but when I run a keyword search of my 
site, I get everything but the squishdot site items. Since my last upgrade I 
have updated the catalog to no avail. Incidentally, I have the zope chat 
example running also, and it shows every single posting by every 
user in the catalog objects, but these also don't show in search 
results (but this may be a design issue for chat). Any help resolving 
the Squishdot issue would be greatly appreciated. I don't care about 
chat very much. Thanks in advance!

[Zope] Overriding server's notion of SERVER_NAME, SERVER_PORT, etc.

2000-08-30 Thread Skip Montanaro


In 2.2.1 I can no longer override ZServer's notion of SERVER_NAME,
SERVER_PORT, etc. from the invoking shell environment.  (I am currently
running 2.0.0, so this may well be true of other earlier 2.1.x and 2.2.x
versions.  With a little luck, I may actually be able to upgrade in the next
few days...)

I run ZServer listening to 127.0.0.2, port 9673.  The only thing that talks
directly to it is my front-end Apache server via its proxy module, so I want
any HTML generated to reflect the visible address and port, not ZServer's
hidden address and port.  I was previously able to force these variables to
be what I wanted by simply setting them before running the server:

SERVER_NAME=dolphin.mojam.com ; export SERVER_NAME
SERVER_PORT=80 ; export SERVER_PORT
HTTP_HOST=$SERVER_NAME:$SERVER_PORT ; export HTTP_HOST
SCRIPT_NAME=/ ; export SCRIPT_NAME

but 2.2.1 ignores these settings.  I made a few simple changes to
ZServer/HTTPServer.py and lib/python/ZPublisher/HTTPRequest.py that use
environment variables as defaults if they're available.  Context diffs are
attached to this msg.  I'd appreciate feedback from those in the know if
these were the correct sort of changes to make or if there is a better
(supported) way to achieve my goal.

Thx,

 Your email address suggests you should be able to find out more easily

Well, I'm pretty sure the answer is "none", but I'm asking to the list
so if someone does have some kind of workaround, the reply will be
public.

 Maybe you could suggest better editing support for FTP or is WebDAV the
 way of the future?
 Mention was made of Adobe GoLive! in Paris, what's that like for doing
 this sort of this?

FTP is limited for this sort of thing because it works on files with
no metadata.

I *think* that the only reason one can't edit DTML methods in a ZClass
definition is that the intermediate steps don't support a FTP
directory interface.  That'd be a nice first step.

I've heard some ideas about how we could edit properties, permissions,
etc. with FTP, some more hackish than others.  Best is probably some
sort of XML text file associated with an item.

But from what I've been reading, the focus will be on through the web
editing whenever possible.  I personally find it much more convenient
to work with python baseclasses  have a python shell looking at the
ZODB in an emacs buffer, so I have a history of what I've done and
seen and can look at the objects  attributes on any level.

And yes, the wave of the future does appear to be with the various
clients that are coming out, Radio Userland being the most recent that
I've heard about.

[Zope] Keeping app logic in Zope (was Paul's talk in Paris)

2000-08-30 Thread Jimmie Houchin

Warning, this message has been composed over several days.
If my thoughts wander, that's one excuse. :)

Simon Coles wrote:
[snip]

 Python products could be endangered species because its managed in the file
 system, which isn't in the "all tiers as managed content" thing.

I guess this means that Python Methods and ZClasses will be the
preferred model?

The reason I wonder is because I am right now beginning development of a
new website. I had been planning on doing most of my development in
Python Products as I currently have no particular need of thru the web
development and I like Python. No particular aversion to ZClasses or
Python Methods just that I know Python products can do what I want and
need.

I understand the the desire to move to a system where the all of the web
app resides within the Zope environment instead of parts on the file
system.

What is the current status regarding incorporating Python Methods into
the Zope core?

Just looked at the Python Methods wiki at:
  http://dev.zope.org/Wikis/DevSite/Projects/PythonMethods/FrontPage

This is issue also affects the Problem paragraph of the Vision Statement
on this wiki, as this broadens the scope of users who choose to use PMs
or reasons thereof.


Also within the desires stated above (to remain with the Zope
environment, ZODB) will there be a means for those with "authority" to
authoritatively do stupid things with Python such as shoot yourself in
the foot? :)

Not that anyone desires to do something stupid, but sometimes the
ability to do harm also enables the ability to do good. That is an
aspect of freedom. Some things require interaction outside of the Zope
environment. What will be the official Zope way of handling these types
of things?

Back again from the Python Methods wiki. :)

A question/suggestion as a part of the Python Methods proposal was to
move External Methods to become a part of Python Methods. This is on the
Current Issues pages.

I added a comment to the wiki. Basically, in light of Paul's comments
and my above desires for necessary expressiveness depending on the
authority of the user and the situation, I think putting External
Methods into the Python Methods part of Zope core would be good. It
would allow for EMs to be in the ZODB instead of on the file system.

As I've thought about these issues and with knowing that I want to use
ZEO I think the above would be of benefit in developing my site. The
less I involve the file system the easier it should be to distribute my
web app logic throughout the ZEO system. I think I'm talking myself into
it. :)

For me this is a change in direction for Zope development thought.

Any suggestions, thoughts or comments appreciated.

Thanks for letting me ramble.

[Zope] Case Studies (good!)

2000-08-30 Thread J. Atwood

Does anyone else love those case studies? I have was grinning ear to ear
reading the new one about replacing all Notes/Domino (which I know and
respect) with Zope. I would love to see more studies on all sorts of
different sites (big, small, database driven, not).

They are also really useful for those of us who need to try and convince
management that 'others are doing it too', which is a cold hard fact of the
corporate world. I would love to see much more (weekly) as well as more on
hardware and hits.

Keep up the great work DC.

Re: [Zope] symbolic links or invisible objects..?

2000-08-30 Thread Dieter Maurer

Geoffrey L. Wright writes:
... symbolic links ...

If your content is simple, i.e. does not contain URL references,
then symbolic links can easily be emulated with DTML methods.

Suppose, you have the following structure:

 A/
 A/A1/
 A/A1/a1
 
 A/A1/an

 A/B1/b1
 
 A/B1/bn

 and you want "A/B1/bi" be a symbolic link to "A/A1/ai",
 then "bi" would be the following DTML method:
 dtml-with "A.A1"dtml-var ai/dtml-with.

 This will not work, if "ai" make a URL reference to an "aj"
 unless "aj" and "bj" have the same id and "bj" is
 a symbolic reference to "ai".


For more complex situations, you may use the product SiteAccess
(-- zope.org) to redirect requests transparently according
to situation.

You may look at
URL:http://www.dieter.handshake.de/pyprojects/zope/Localizer.py
This is used as a SiteAccess AccessRule for localization.
Requests going to a folder controlled by this rule are
served from this folder, if possible.
If not possible, the request is redirected to a different
folder.

I think, this method can be abused to get what you want.

Re: [Zope] Apache: mod_perl, mod_rewrite, prefix

2000-08-30 Thread Hung Jung Lu

(1) I have mod_rewrite statically
(2) I have mod_perl statically
(3) prefix is /usr/mydir

Okie, I figured it out. So I'll reply to myself. :) By the way, I am on 
Linux platform.

So the appropriate commands are

(1) Download latest apache and mod_perl. Unzip and untar them.
(2) Place the untarred mod_perl-1.24 into your apache_1.3.12 folder.
(3) cd into the mod_perl-1.24 folder.
(4) perl Makefile.PL \
USE_APACI=1 \
APACI_ARGS='--enable-module=rewrite' \
APACHE_PREFIX=/usr/mydir
(5) make
(6) make install (this will install the the httpd executable but not 
override the existing httpd.conf file. If you want to play safe, make a 
backup of the httpd executable before installing the new one.)

C'est tout!

[Zope] Newbie SQL problem: Query Error: Cannot render query template

2000-08-30 Thread Farrell, Troy

Hello.

I am running Zope as a service on NT4WS.  I have multiple MS Access
databases connected to different ZJetDAs and I am not able to modify the
data in them with SQL statements.  For example, INSERT INTO test VALUES
(dtml-sqlvar value_one type=string, dtml-sqlvar value_two type=int)
returns the error "Query Error: Cannot render query template".  Can you tell
me what the cause is.  I think it might be a permissions problem, but I have
everything wide open and I can't figure it out.

Thanks.

[Zope] Apache: mod_perl, mod_rewrite, prefix

2000-08-30 Thread Hung Jung Lu

Hi,

Although this is more an Apache question, I would guess that a lot of Zope 
users have gone through exactly the same problem I am going through, so I 
might as well try it out here.

As you can probably tell, I am trying to hook up Zope and Apache via PCGI. 
The thing is, I need also mod_perl, and my Apache root prefix is 
non-standard (not /usr/local/apache). I want to build Apache from source 
such that

(1) I have mod_rewrite statically
(2) I have mod_perl statically
(3) prefix is /usr/mydir

Now, those are three requirements, and things got too complicated. I  know 
how to do (1) and (2) together, I know how to do (1) and (3) together, but I 
still fail to do (1)(2)(3) all together. Anyone cares to share their 
experience? I want a final httpd executable, so that I can simply copy and 
replace my current copy of apache.

I have read:

  http://perl.apache.org/guide/install.html

but I am still a bit confused.

Thanks,

Hung Jung

PS- I think mod_perl is an example of big failure when it comes to 
installation, since it tries to control and override the apache installation 
process. What a mess! In comparison Zope product installations are as easy 
as drag and drop.

 Curtis,

 Could you describe how often does the problem happen? How many session
 users goes to the site? You mentioned about a month of public usage. During
 that month, did you have one single incident? How many sessions happened
 during that month?

So far, we have one recorded incident, and one anecdotal (from internal) 
incident.  I am having some more extensive testing done soon, so we can try 
to pin down further the exact circumstances which cause this problem.

The site is used for issuing product return authorities, and so far, over 160 
RAs have been issued.  Yes, it is a fairly low traffic site.  Session data is 
retained between visits (a side effect, but a welcome one), so I really 
cannot be sure of how many sessions were used.

 All key-based session management systems are intrinsically unsafe, since
 other people can tap into your session, with non-zero probability, if the
 key-length is finite. The only hope is to make the key long enough, so even
 if the hacker has a supercomputer, it would still take him/her the age of
 the universe to crack into your website. One thing I mentioned to Pavlos
 (and/or Anthony Baxter?) before is that the key lengths of their cookies
 are a bit too short. For my HappySession product (another session
 management product, which is RAM based), I cranked up the key length to 128
 alphanumeric char key, exactly because I wanted no key collision for a long
 long time. :)

Well, yes and no.  This really depends on the sensitivity of your data, and 
how likely it is for someone to try to crack your site.  In this case, both 
are fairly low, so the key strength is fine, IMHO.

 Hung Jung

[Zope] ANNOUNCE ZEO 0.3 Released

2000-08-30 Thread Jim Fulton

A new release of Zope Enterprise Objects (ZEO) 
is available at: http://www.zope.org/Products/ZEO.

This release fixes a bug that caused spurious conflict errors
and that could eventually make it impossible to make changes
without restarting a ZEO client (e.g. Zope process).

The release also has two enhancements when running
the ZEO server on Unix:

- When the storage server start script is run as root,
  the script will switch to a different user (nobody by
  default). There is a new '-u' option that can be used to
  specify the user.

- The storage server will gracefully close served storages when
  the server is killed with a SIGTERM or SIGHUP. If a
  FileStorage is being served, then an index file will be
  written.

If you encounter problems with ZEO, please report them
using the ZEO issue tracker at:
http://www.zope.org/Products/ZEO/Tracker.

2000-08-30 Thread Kapil Thangavelu

I saw this email with some interest since i had an offlist conversation
with some of the people at nipltd regarding a mailing list project, but
i chose to do it outside of zope because of lingering doubts about
zope's suitability(more ZCatalog) for the task.

  Can you be more specific?
 
 Andy can fill you in on the specifics.
 
   What's insufficient about the current
  implementation?
 
 It doesn't scale well, especially for things where you have lots of new
 data arriving (this is the BTree problem, I think...)
 
 It has no published and well defined query syntax (there's patches here,
 bits there, but no definitive document on how to use it, how to batch
 with it, how to perform complex and structured queries, particularly
 with TextIndex'es)
 
 Don't get me wrong, it is very cool, but only kindof 70% there :S
 (and I get the impression that doing the remaining 30% properly would
 require a rewrite...)

more of the same...
 
I think that zcatalog is great for simple property indexing but it has
some signifigant drawbacks for its most common use, which is mass text
indexing, and searching. As object an catalog, its fine, But i think as
a mass text indexing/searching machinery it bites. I think Zope could
really use either a companion to zcatalog for text searching or a
replacement. If i'd like to index 50M i'd like not to have my search
take unreasonable long, give erroneous results, thrash my machine
because i choose to index it at once, yet these are all things that i've
experienced with zcatalog since i started using zope. for sure its
gotten much better, but it still can't handle my use cases. So i've
accepted that ZCatalog isn't a site wide nor a scalable tool.

ok so the question(at least to me) than becomes what to implement. i'm
not totally sure... i've taken a look/leaning towards Evolution's text
indexing (libibex), 

i consulted some of the evolution developers and this is the response i
got 8/5/00(us)


You probably dont want to use libibex as it is now - all indexes
are stored in memory for example, and it uses a lot of memory
as well (uses gtree's).  It will handle 100MB of mail fine enough
though on modern hardware, if you ahve the spare memory.

At some point we are going to change the backend to use a disk
based storage, using the search engine used in nautilus (can't
remember what its called), although we will probably make a wrapper
so the api should remain.


which takes back to square one. i am convinced of the  need for
full-text reliable search on a site or a part of site. but i'm unsure of
what the best way to do it would be.

 As an example, we've been trying to do Zope-based versions of the
 mailing list archives for a coupla months now and the Catalog keeps
 exploding in different ways (huge resource consumption, even for only
 30K messages or so, no matter what storage is used)
 
 Then there's the ubiquitous 'KeyError's and other associated weirdness,
 all of which leaves me feeling a lot less than totally confident in the
 Catalog ;-)
 
 comments very welcome,

Karl I've never been able to do much.  What I have done is use

Re: [Zope] Bug Tracking Product Recommendation?

2000-08-30 Thread Kapil Thangavelu



You could explore the Tracker Product available from zope.org's cvs. its
used for zope. it is unsupported.

 It would also be nice if it was tied to a ODBC compliant database
 like MS SQL or Access!

nope. did you mean ODBC or MS compliant;)

the only DB solutions i know for bug tracking are bugzilla available
from mozilla.org's ftp (which is tied to mysql). and the SDM module from
arsdigita's ACS(either oracle or postgres).
