 For example a method in UML can be generated as a DTML

I would be happy with a generator that supports DTML generation at

 this could be defined through stereotypes on the UML side, but that is still a big

Right.
 
 Before I go into generating zclasses I want to complete and publish the

Re: [Zope-dev] OracleStorage, and possibly others

2000-11-29 Thread Chris McDonough

If you're at all interested, Kapil, it'd really be great if someone were to
take over InterbaseStorage.  It needs to be changed to use Bob Tierney's
newer multithreaded GVInterbaseDA Python DB-API adapter (Kinterbasdb doesn't
seem to get along with newer versions of Zope, and it's singlethreaded).
Additionally, the pack code is broken.  It would be a big win for folks who
want a versioning, undoing storage backed by a relational opensource
database.

 Of course it would, for the same reasons as OracleStorage (eg
 FileStorage/Data.fs is inefficient)

Actually, it's the other way around.  OracleStorage is 30-to-50 times slower
than FileStorage on writes.  Reads are slow too but the slowness is somewhat
negated by caching.

Chris, that's only true for small databases. At about 100M of
Data.fs, OracleStorage starts being faster. It depends on
hardware too. We made some benchmarks on a major Brazilian
portal, and well, it's currently running OracleStorage.

Anyway, I said "inefficient", not "slow".

 I disagree alot. I'd rather have clear documentation of intended

Yeah! ZSearch (thanks Michel, I did know about it but didn't express my
point very well ;-) seems like a good example of this to me. The
_interface_ deosn't seem to exist, just several implementations and no
actual documentation. I wonder if the implementations all have the same
functionality? They would if the interface was a contract...

 Please note that these points were argued extensively on the Python
 types-sig a couple of years ago.

What was the outcome?

Well, sorry to correct you, but there isn't an _interface_, or at least
one that's published. 

 The Z Search Interface
 is well defined (not well documented)

ie: there isn't an interface, there's just similar (I bet they're not
identical) implementations in ZSearch, Catalog, ZSQL and ZNetwork
(whatever that is ;-)

 The 'Z Search Inteface' object is one tool in particular
 that uses it, perhaps you can in imply the interface from that since it
 is not documented.

As I said earlier, I totally agree with Jim that a weak interface like
this isn't a lot of use. What happens next time someone tweaks the
catalog and changes the functionality? Does that mean the interface has
changed? How can all the seperate implementations keep up?
I actually tried to make Squishdot implement the Z Search Interface when
I moved to using the catalog, but it appeared at the time that ZCatalog
didn't actually work properly with Z Search anyway. All of which kindof
illustrates my point :-S

The main thing for me is that the implementation is documented
somewhere, which it isn't. Of course, it'd be much better if it was a
proper interface as is being discussed here. Mindyou, it'd also be great
if python had native interface support. What does Guido think about
that?

At 06:19 PM 11/29/00 +1100, Itai Tavor wrote:
Hi,

I'm trying to figure out the right way to implement a set of classes 
and roles in ZPatterns. I asked some questions about this a while 
ago, and then went away and did some learning, but I'm stuck again 
and I'm afraid I need to ask more questions.

I have two types of actors - Person (with properties name, phone, 
email, password) and Organization (with properties name, phone, fax, 
business_number).

I also have two participants - Customer and Reseller. Each 
participant can be either a Person or an Organization.

The participants can fill several roles, like OrderingEntities, 
BillableEntities, etc.

Starting from the bottom, I create a Specialist for each role, each 
one with two virtual Racks - customerRack and ResellerRack, so I can 
refer to an OrderingEntity without caring if it's a Reseller or 
Customer.

My problem is in implementing the Participant Specialists and storing 
Participant and Actor classes. Do I create Specialists for the 
Actors? It seems to me that since there is either one Person or one 
Organization per Customer, then the actor object should be created in 
the Customers Specialist. So Customers will have 3 Racks - 
defaultRack (using Customer object), personRack (using Person object) 
and organizationRack (using Organization object). Does this make 
sense?

I think what you want is to have an Actors specialist containing a
personRack and organizationRack.  That 
is, treat "Actor" as a role relative to either Customer or Reseller.

The reason I say, "I think", is because I'm really not clear on why you're
doing certain things here to start with.  See below.


If this is a good way to do it, how do I handle creating and 
accessing the Person and Organization objects? Do I call 
personRack.newItem(newCustomerId) in the script that creates the 
customer? Or do I somehow do it in a SkinScript in defaultRack? And 
how do I get to the Person data? With an attribute provider? Or in 

Here's a red flag: why are you creating a person when you create a
customer?  If a person is something that you only make when you have a
customer, then the actor-participant-transaction pattern isn't really
valid, IMHO.  For Actor-Participant-Transaction to make sense, you have to
have Actors that exist seperate from the Participants.  While it makes
sense to be able to create an Actor at the same time, your model needs to
also include a way to select an *existing* Actor as the Participant,
otherwise you are not gaining anything from the A-P-T pattern and you might
as well just have the Participant.

Here's a pattern for mapping A-P-T interactions onto ZPatterns, however...
If you are doing A-P-T, make sure you use a Specialist for access to the
Actors.  For example, in some applications Ty and I write, "acl_users" is
designated as the Specialist for actors if all actors in the system have to
be able to use the application.  The user interface and implementation for
creating and/or selecting actors to fill a participant role is placed in
the actors' specialist - acl_users in our case, or perhaps a specialist
called "Actors" in yours.  (But I'd recommend you use a domain-specific
name, if possible.)  So you would not be worrying about whether to create a
person or organization or what fields they need or anything else in the
specialist for your "participant" objects.  Indeed, you wouldn't be
worrying about whether a new one was being created, or an old one selected,
if you delegate that aspect of the UI to the actors' Specialist.



Also, if Actors are stored in the Specialists that implement the 
roles they participate as, there is no place to store methods that 
are common to an Actor regardless of role - for example, a method 
that checks if a password is secure enough and called when adding a 
Person object. So I either duplicate these methods in every 
Participant Specialist, or create more Specialists - which seems like 
a waste either way.

Again, this is solved by using a specialist for the role "Actor".


Another problem is how to edit these objects - if I have a form which 
includes fields for a Customer properties and for the properties of 
the Person object linked to that Customer, can I change the Person 
object from the Customer SkinScript? I don't think I can do this:

   WHEN OBJECT CHANGED STORE name, password USING
 
personObject.propertysheets.manage_changeProperties(name=self.name, 
password=self.password)

Right? Because name and password are not properties on the Customer 
DataSkin. So I have to call person.manage_changeProperties(...) in 
the method that changes Customer... it seems to me that I always end 
up doing object connections work in methods and the SkinScript can't 
help with anything :(

You're making this entirely too hard.  The Prime Directive of ZPatterns
design is, "if it looks too complicated in any one place, your design is
probably wrong.  If almost every individual piece looks simple, even though
the whole is 

[Zope-dev] Meta-data clarification and Interface interfaces

2000-11-29 Thread Michel Pelletier


In my proposal:

http://www.zope.org/Wikis/Interfaces/ExtensibleMetaData

I mention interface object meta-data like pre/post conditions.  This
spurned a lot of interesting conversation, and I wanted to clarify some
bits that I picked up from the thread.

The proposal is not in any way trying to define what types of meta-data
are interesting, this is, rightly, application dependent (for example,
Zope would find security assertions interesting, other applications may
not).  The proposal is just proposing a mechanism for associating any
kind of meta-data with an interface object.

Dont get me wrong, the information on pre and post conditions was really
interesting, especially Tim's description of Eiffel's particularly
strong methedology that made me glad I don't work for the government.

In the interest of clarifying what these interface objects are, I have
created an Interface interface description:

http://www.zope.org/Wikis/Interfaces/InterfaceInterface

This describes interfaces, attributes and method objects and how they
are used.  I can forsee creating interface objects for these interface
objects.

The ones marked **Proposed** are the ones I am most interested in
getting feedback on.

Thanks!

 Seriously, AFAIK it still works, and it's mainly just stalled waiting

 that was blocked on having an updated Python BerkeleyDB module for a

 The main thing BerkeleyStorage is lacking is interest -- I don't need it

I think a BerkeleyDB3-based Storage would be a very cool option

Once upon a time, I had planned to do (and had some code towards):

no-versions, no-undo
versions, undo
versions, undo only within versions

with a "table" structure such that you could migrate from one to
another.

The last option is possibly useful for sites with objects that change a
lot (so you don't want undo), but where you want to use versions for
code development (which requires undo...  note the lack of a "versions,
no-undo" combo.  That one won't work usefully, because you can trivially
get stuck.  You get something locked in the version, and there's no way
to recover short of committing the entire version. "no-versions, undo" is
possible, but doesn't seem to really buy anything)

Re: [Zope-dev] RFC: Python/Zope Interfaces

2000-11-29 Thread Dieter Maurer

Ken Manheimer writes:
  The separation need not mean that the specification is hard to access from
  the implementations, either for documentation or for runtime enforcement.  
Good!

But, objection will come later.

  However, it *does* run contrary to the literate programming notion of
  weaving together the description of software with the code.  When you have
  multiple implementations that satisfy an interface, having a copy of the
  interface spec with each implementation can lead to the drift described
  above.  If you *want* discrete interface definitions with integrity across
  implementations, you have to avoid this multiple, potentially conflicting
  copies of the specification.

What I really want is that the implementation fulfills its contract!

If you change the specification but do not adapt some implementations,
then it is essential, that the implementation somehow tells,
which specification it implements.
One way to achieve this, it to have the specification integrated
(with some tool to extract it easily as e.g. in Eiffel).
Of cause, there are other ways to achieve this -- such as
efficient linking to the specification and careful versioning
of the specification documents.

If you do change the implementation, then the specification
can probably be changed at the same time.

I should stress, that I do not necessary call for a physical
copy of the specification/interface to be present
in the implementation. An unambigous and correct reference,
preferably interpretable by documentation generators,
should do as well.

  I think you're asking for something internally contradictory, and not
  seeing that.
If I do, indeed, I do not see it.

Jim gave the example:

  If someone builds him a house, he wants a contract that
  lays out the obligations. The house builder should
  fulfill this contract.

  Good.

When I buy a house, I expect from the vendor a description,
what features the house *REALLY HAS* and not what
features the vendor would like the house to have.
Based on this description, I will decided whether or not
I will buy.

That's probably the difference between the specification
(created before the implementation starts and used
as a guideline for it) and the documentation (that describes
the concrete instance). Ideally, both are identical.
In practice, there are often discrepancies.

2000-11-29 Thread Phil Harris

Ot,

I've seen this myself.

Are you using IE5.5?

It seems that on occasion when you have active desktop and outlook express
running that win98/2K remembers the authentication details between instances
of IE5.5.

Realising that Outlook Express uses IE to display mail and active desktop is
also based on IE then this starts to make some sense.

It's only happened to me when using W2K but it definitely happened and made
me doubt my sanity for a while ;)

I reinstalled the machine and downgraded to IE5 to get rid of the problem.

One ray of hope though is that IE5.5sp1 seems to cure the problem, at least
for me.

Subject: [Zope] Help!!


 Hi,
 I'm new to Zope and have just installed Zope on a Win98 PC.

 I'm trying to install squishdot and TinyTable, but Zope tells me that
 superuser has no permission to install the above products.

 I have created another user called 'admin' with Manager priviledges but I
 don't know how to logout of superuser and login as 'admin'.

 I have tried shutting down Zope and closed off internet explorer and
 restarting again but I still get into superuser.

 If I need to login as a non superuser, how do I do this?

 I have looked for all relevant documentation but can't find anything on
 this.

 Your help would be appreciated.

 TIA

Re: [Zope] Help!!

2000-11-29 Thread Ot Ratsaphong

Hi Phil, Eric,

Thanks for your responses, Chris McDonough sent me a message earlier today
and told me what I had to do.

My IE5.5 authentication settings were set so that it would automatically log
me on to any application (ie. save my password). Because the first time I
logged in was as 'superuser', it logged me in as 'superuser' everytime.

Once I disabled this setting and set it to "Prompt for User name and
Password", the login prompt appeared again.

see: Tools-Internet Options-Security-Custom Level...

I understand but this seems a deviation (I don't say a violation since the RFC

9.4 HEAD

   The HEAD method is identical to GET except that the server MUST NOT
   return a message-body in the response. The metainformation contained
   in the HTTP headers in response to a HEAD request SHOULD be identical
   to the information sent in response to a GET request.

It is certainly a big problem for debugging or for robots which assume they

[Zope] Zope restarting itself?

Hi listies,

maybe someone of you heard of a feature that Zope can restart itself when
it dies abnormally. (Linux/Unix version). I found such a service for Windows
NT, but not for Linux, although I am sure that I saw it a while ago

this task?

 how does the authentication work?
 do any files have to be at special places for authentication?
 do any files need any special permission for this?

 my system
 i have it run under wwwrun:nogroup and the directory

Re: [Zope] ZTopics not working right --Error Value: Vocabulary

From what I remember, the TextIndex code wants to acquire the catalog's

think this is an option during the instantiation of a catalog), this can
occur.  This is arguably a bug.  The vocabulary object should probably not
be acquired.  Do you think you can submit this to the "Collector" at

 Yes, this works fine on the Mac. I suspect the difference is because 
 on the Mac they are taking the http content types to figure out the

Thats just the way Windows works. Somehow M$ chose to determine the
filetype by the file extension, and the file extension only (and then
they chose to _hide_ the extension by default... ;). 

A somehow related issue is that IE seems to prefer file extensions over
any HTTP headers, MIME types and such.

Mac has a forked filesystem keeping type information separately. Thus no
problem with names.

[Zope] strange behaviour of ZSQL methods

2000-11-29 Thread Martin Winkler

Hi listies,

something strange is happening with my ZSQL methods. I have a huge query 
that works great when testing it in the management-interface - it returns 
about 10 records or so.
but when I implement it into a dtml-method getting the parameters via 
X-Y-GMX: $flush
REQUEST as usual, I am getting the whole database in return.
I'm quite sure that it's my own fault, so I'd like to see the translated 
SQL-query in the dtml-method to check for the wrong fields. Is there a tag 
for it like: dtml-var MyZSQLQuery showRenderedSQLsource ?

This problem drives me nuts since already two days :-((

Re: [Zope] ZopeWeaver?

2000-11-29 Thread Jason Cunliffe

Hello

Thanks for all the comments so far on this topic. Hope to hear more.

I have been looking this morning gain at the Extending Dreamweaver docs.
[on Win32 its typically at
C:\Program Files\Macromedia\Dreamweaver 3\Extending\ExtendingHelp.htm ]

It seems to me that by using the XML-based TAGSPEC, and then the Dreamweaver
Javascript DOM, it should be possible to open index_html or anything.dtml in
a fully controlled manner. It looks like this can avoid any dependancy on
Win32.

SOME EXAMPLES:

DWfile.read()
The following code reads the file mydata.txt and, if successful, displays an
alert box with the contents of the file.

 var fileURL = "file:///c|/temp/mydata.txt";
var str = DWfile.read( fileURL);
if (str){
  alert( fileURL + " contains: " + str);
}

..

In Dreamweaver 3, extensions are no longer limited to working within the
local file system. Dreamweaver now provides a mechansim for getting
information from and sending information to a web server via hypertext
transfer protocol (HTTP). This chapter describes the HTTP API and how to use
it.


MMHttp.getFile()
The following code gets an HTML file, saves all the files in the
Configuration/Temp folder, and then opens the local copy of the HTML file in
a browser:

 var httpReply =
MMHttp.getFile("http://www.dreamcentral.com/people/profiles/scott.html",
false);
if (httpReply.statusCode == 200){
  var saveLoc = httpReply.data;
  dw.browseDocument(saveLoc);




There's lots more, but these seem like the 2 essential ones [+ their
.write() counterparts]



The potential advantages I see for Zope are:

- PROFILE
[improving Zope's general visibility and acceptance for new projects] Having
a set of Zope Dreamweaver Extensions in itself would help promote it.

- WORKFLOW
[making Zopesite development with Dreaweaver much friendlier for
designers/programmers etc.]

- DESIGN
[ better integration with Macromedia's graphic toolset will make it easier
to for professional designers to develop more professional looing ZopeSites]

- FEATURES
[There are many features available now in Dreamweaver3+ which can be
leveraged to prototype and build higher level Zope templates design and
interface]


So my questions are what Javascript 'ZopeWeaver' extensions would you really
like to see?

 I understand but this seems a deviation (I don't say a violation since the RFC 
 says SHOULD and not MUST) from the RFC on HTTP (2616):
 
 9.4 HEAD
 
The HEAD method is identical to GET except that the server MUST NOT
return a message-body in the response. The metainformation contained
in the HTTP headers in response to a HEAD request SHOULD be identical
to the information sent in response to a GET request.
 
 It is certainly a big problem for debugging or for robots which assume they 
 can test with HEAD.

The SHOULD in that text is there _because_ not all web environments can
reliably generate a HEAD response without invoking undesired side-effects.
It is easy with a static website, where there won't be any side effects to
only sending the headers going with a URL, but with a dynamic web server
this is quite different.

If this is really a big problem for you I suggest you upgrade to Zope
2.2.0 or higher. Quite some trouble is taken to ensure that a more
meaningful content-type is returned:

- If the published object has a 'content_type' attribute, it's value will
  be used first. 

- If absent, the ID of the object will be used to guess it's content type.
  Only object names which use extensions benefit (for example: logo.gif
  is probably 'image/gif').

- If no guess could be made, the property 'default_content_type' is used.
  DTML Documents and Methods define this as 'text/html'.

- Only when all three steps above fail will the content type
  'application/octet-stream' be used.

I believe that only the 3rd step was added in 2.2.0b1, so you could try
and add a 'content_type' property to DTML objects that *must* return a
correct content-type.

If the implication here is that the corresponding GET request could have
meaningful side effects (i.e. not just changes to caches, logs or hit
counters), then strictly it would be breaking the semantics of GET, which is
meant to be idempotent - capable of being called multiple times without
meaningfully changing the state of the server-side system or application.
Requests that can change the state are supposed to use POST.

Re: [Zope] Factoids for supporting zope

2000-11-29 Thread Simon Coles

A clarification here. It refers to Digital Creations being a long term
viable business entity.

When we made "The Zope Decision", one of the attractions of the 
Zope/DC relationship is that whilst it is obviously very nice for 
everyone if DC continues to exist, and continues with their current 
strategy, we aren't held hostage to their fortune.

Consider a possible experience with a proprietary vendor. At the 
moment you have an excellent relationship with them, the product is 
good, and their future plans are encouraging.

Then they change strategy, or get bought out - not an unlikely 
outcome in new markets where things are still playing out. Then all 
of a sudden you find:
- the pricing has changed dramatically
- the product has moved
- the vendor no longer cares about you

Ouch. Have you ever had a vendor "end of life" a product on you?

With Zope, that's not going to happen. If DC change their strategy 
dramatically then:
- if there's the demand, someone else will step into their shoes (like
  maintaining the ages old version of Zope that DC not longer support)
- if you want to, you can do it yourselves (or pay someone else)

For my money, going with a proprietary vendor is even more risky than 
going with an Open Source product. The proprietary lock in means the 
vendor holds all the cards, and you hold none.

The cool thing about DC/Zope is you get the best of the Open Source 
and commercial worlds - its Open Source when you need it, but there's 
a nice cuddley vendor to buy support and consulting from (as well as 
a load of independent organisations :-)

Zope gives you more choices, and total control over your future. 
Proprietary, closed source solutions are just lulling you into a 
false sense of security - until its no longer in the vendor's 
interest to deal with you.

I fear this is anywhere in some howtos,

How can I get properties of a DTML-Documents

At least I couldn't get the "Find" in Zope's webinterface

[Zope] Help with Nested ZSQL methods

2000-11-29 Thread paul_s_johnson

I thought I saw this answer to this one time on http://www.zope.org once,
but for the life of me I cannot seem to find it.

I have two ZSQL methods, both tested and work.

ZSQL method 1
===
method id= sql_get_schedules
SELECT * FROM Schedules WHERE JobID = dtml-var JobID ORDER BY SchedSeq

ZSQL method 2
===
method id= sql_get_items
SELECT * FROM Items WHERE SchedID = dtml-var SchedID ORDER BY ItemNo

These two tables are linked by the common field "SchedID"


Here's the operative part of the dtml method that calls these methods:
==
dtml-in sql_get_schedules
 TABLE BORDER="3"
 TRTHItem No./THTHDescription/THTHMn/DOT
No./THTHUnits/TH/TR
 dtml-in sql_get_items
  TR
   TDdtml-var ItemNo/TD
   TDdtml-var Description/TD
   TDdtml-var MnDOTNo/TD
   TDdtml-var UnitDescription/TD
 /TR
 dtml-in
 TABLE
/dtml-in
==

I get the error:

Error Type: Bad Request
Error Value: ['SchedID']

I suspect there is some type of namespace-related problem going on here
where the var SchedID is not getting passed to the internal ZSQL method.

P.S.: I must Lotus Notes ( http://www.iarchitect.com/lotus1.htm ) at my

Re: [Zope] Ah, I found it -- Estimate of community size

2000-11-29 Thread Jimmie Houchin

I would have to say that both are accurate at the time they were given.
However, neither will be a truly accurate measurement of the users of
Zope and the Zope community.

They each measure different things. One measures the people who have
"joined" Zope.org.
"""The extremely large Members folder (11139 of you!)"""
The other measures subscribers to the mailing list.
"""There are 1617 members of [EMAIL PROTECTED]"""

There are a few people who have different identities on the Zope
memberships. There will also be possible duplication on the mailing list
due to different email addresses. There are also people who neither join
Zope.org nor subscribe to the mailing list, but who have nevertheless
downloaded and use Zope.

There also are people who have been on the mailing lists, learned and
then subsequently left the lists, but still use Zope. There are also
those who no longer do.

So, who knows what an accurate figure would be? 
And I can't tell you if there are any dimpled chads. :)
But as you can see there are many more unique visitors than either of
the numbers.

Also, keep in mind that the Zope community on [EMAIL PROTECTED] is an active
and vibrant community. As Zope matures, grows into it's own and the
documentation catches up, it will get even better. The future is bright.
:)

 If this implies that you are considering using Zope's PTK, then you

 Digital  Creations for PTK because PTK is not a released product. If 
 you think you  may need such support before PTK gets to 1.0, then you 
 had best not use the  PTK. But that's no reason to not use the rest of 
 Zope. 


This needs to be clarified.   We actively do consulting with the PTK.  
If you want to enter into a consulting contract with Digital Creations 
that involves the PTK, that's not a problem.

If you decide you want to use the PTK yourself, there exists a mailing 
list and a product tracker. (see http://www.zope.org/Products/PTK ) The 
PTK is under heavy development and is not a full release yet, so that 
does need to be taken into account if you wish to use it yourself.

This is an FAQ.

You already know the searchable list archive at NIP?

Z SQL methods do *NOT* take parameters from the DTML
namespace. They only look at "REQUEST".

You have two options:

 1. put your parameters into the REQUEST object:

dtml-call "REQUEST.set('myparam', myparam_value)"


 2. call the Z SQL method with explicit parameters:

dtml-in "myMethod(myparam= myparam_value, )"

Yup. This is what I do and use htmlkit for those small index_html or
other DTML method files that don't represent html content, but more
logic.

 Ah.  Well, my opinion is that it'd be fairly dangerous

 Zope and the Zope community can "make up for" the other
 half of the capital they need to develop the software they
 want.  So what's the decision they're trying to make?  Whether
 to develop at   all?
 
  Whether to go with portal products from Plumtree or iPlanet.
 
 If this implies that you are considering using Zope's PTK, then you should
 be aware of this: You can *not* get commercial support from Digital
 Creations for PTK because PTK is not a released product. If you think you
 may need such support before PTK gets to 1.0, then you had best not use the
 PTK. But that's no reason to not use the rest of Zope.

As the current product lead for the PTK, and a DC consultant who
uses it every day in developing software for customers, I wouldn't
say that your statement is, perhaps, misleading.  While I'm not the
person who negotiates support contracts for DC, I do know that DC
sees the PTK as a key element of our future growth plans.

In the meantime, most people get their support fo using the PTK
from the place they get support for using Zope:  right here on

[Zope] adding roles to Zope in Product.initialize()

2000-11-29 Thread Randall Kern



I wish to restrict the creation of a class 
(SpokeSite) to people with the "Add Spoke Site" permission, and in turn only 
provide that permission to people in the 'Super-manager' Role.

When I call ProductContext.registerClass for my 
SpokeSite class, I can pass the permission argument with the tuple ('Add Spoke 
Site', 'Super-manager'), which does a good job of limiting the availability of 
my class (just as I desire).

However, I would like my Product to automatically 
create the 'Super-manager' Role, if it doesn't exists. The bad part is 
that this role needs to be added before any of my objects exist, which makes it 
hard...

I've got it *working* by cheating, and using the 
private __app attribute of the ProductContext. Is there a better way for 
python Products to alter the Zope installation (add Roles, create Folders, etc.) 
during installation?

Thanks!

 From what I remember, the TextIndex code wants to acquire the catalog's
 Vocabulary subobject.  If you created your catalog without a Vocabulary (I
 think this is an option during the instantiation of a catalog), this can
 occur.  This is arguably a bug.  The vocabulary object should probably not
 be acquired.  Do you think you can submit this to the "Collector" at
 Zope.org (http://classic.zope.org:8080/Collector)?


Umesh replied:

 The catalog in question is the portal_catalog from the PTK which has
 an accompaning Vocabulary object.
 
 I will do as you requested and submit this to the Collector.

The 'portal_catalog' object is actually a wrapper around a

Chris,

I also had great difficulty in finding any relevant documentation... (re:
specifics regarding text and field searches against a ZCatalog)...

So, it sounds like we should (a) make a feature request and (b) make a
documentation request.  I'm more than happy to write up and submit such
requests.  Heck, I'd been even happy to tackle coding the improvements, but
I'd need someone very familiar with the ZCatalog implementation to give me
some direction to get me going (i.e., how he or she would recommend the
change be implemented).

But, I'm quite new to the Zope world, and have no idea where one goes to
request a feature, or request documentation, or even where one goes to offer
help coding.  Anyone want to point me in the right direction? ;-)

No... the stock answer is "use local roles".  I had a proposal up to create
an interface for programmatically adding roles on dev.zope.org but it's
quite dead.  The thought behind this is that actual roles are reserved for
administrator usage, not developer usage.  Which leaves us in sort of this
weird state that I'm not completely comfortable with, but don't have time to

 By "use local roles", you mean do it manually, through the web ui?  I don't

You can do it in the manage_afterAdd() method of your class:

---CUT---
def manage_afterAdd(self, item, container) :
# create the role only if it doesn't exist (acquisition)
if "yourrole" not in container.valid_roles() :
self._addRole("yourrole")

#

So the role will be created in your instance during its creation, but only
if doesn't exist yet (or can't be acquired from the above level).

hoping this will help.
