Lalo Martins wrote: Well, two betas of OracleStorage in one day, then a month and a half of silence. What's the status? From our perspective, it's what it was then. We built it for a customer who later decided they didn't want it. I'm glad to hear you found it useful. What about the other Storage projects? BerkeleyStorage has been dead for an year, and I heard pretty nasty words about InterbaseStorage. What about someone who wanted to try to port OracleStorage to Postgres or some other RDBMS? We're working on a new suite of Berkeley storages that we are writing to the the latest Berkeley database APIs. As Chris pointed out, these are based on a new Berkeley DB extension that Andrew Kuchling started and that Robin Dunn is finishing. There are a number of interesting new features that will eventually result from these storages: - A new pack/garbage collection approach. The current storages perform a mark-and-sweep garbage collection when packing. It turns out that this really isn't very scalable. I'm going two switch to using the same garbage-collection strategy that Python uses, which is reference counting supplimented by an incremental cyclic garbage detection algorithm. I have a simple storage (no undo or versions) that needs no packing of your data structures are free of cycles. I'm hopeful that we can make packing automatic and incremental. - Undo-log generation will be much faster, at least for common cases. Generation of undo logs (for selecting transactions to undo) is becoming a significant performance problem with FileStorage. - ZEO verification, performed when a client with a persistent cache starts up, will be much faster. - Policies to control whether multiple revisions are stored or whether revisions are removed by packing on a object-by-object or transaction-by-transaction basis. For example, you could have a poll/votting product that didn't allow undo of and didn't require storing multiple records for votes. This would be cleaner than mounting a separate database with a simple storage. You could keep significant historical revisions for important objects, such as Wiki pages, templates, scripts, etc., with a policy to decide which revisions are significant. - The ability to set policies to implement quotas. I expect that we'll work out a lot of these ideas for Berkeley storages and then implement them in OrcaleStorage. Others should then be able to map the implementation onto other storages. I'll note, in passing, that it's much nicer working these ideas out with the BerkelyDB API than dealing with PLSQL or Python SQL. We are also working on ZEO storage replication. This may have a big impact on the storage API, or lead to specialized APIs for replicated storages. Please help stamp out Data.fs! :-) I don't think Data.fs will go away. I do expect it to be relagated to initial evaluation and development projects. Use of Berkely DB in transactional mode requires a significant andminstration commitment. Log files need to be purged. Backup and recovery processes need to be in place. A similar cost is associated with using Oracle and many other databases, I expect.

[Zope-dev] Re: [Geeks] Re: Interface Meta Data proposal
Guido van Rossum wrote: Is security really a part of an object's interface? I thought this was more of an implementation thing. Good point. Certainly in Unix I can have two things implementing the same interface (e.g. two named pipes) with different security settings (i.e. modes). However some security stuff can be part of the interface too: e.g. the fact that a Foo object has Read, Write and Execute permissions is usefully specified as part of its interface. Whether a particular Foo instance has a given permission for a certain user is up to the instance. I think we're talking about a different level of security setting here. In unix, you have certain fixed permissions (e.g. read, write, execute). The OS maps these permissions onto certain low-level operations for the few objects it knows about. This is about mapping permissions onto objects, rather than deciding what users or groups have what permissions on an object. In Zope, the programmer defines abstract permissions and decides how to map the abstract permissions to object operations. It is this mapping that makes sense for interfaces. Like Unix, Zope has a separate mechanism for deciding what users/roles have what permissions on objects. This should not be part of the object interface. These settings are done by users/administrators. Jim -- Jim Fulton mailto:[EMAIL PROTECTED] Python Powered!

[Zope-dev] ZPatterns: using PythonMethods from Skinscript
hi out there,
this is my first posting on this list. Right now I
think
this is the right place to ask details about
ZPatterns.
I think a ZPatterns-Mailinglist should be set up,
where
people like me, working hard to get the "Zen of
ZPatterns"
can discuss questions related to USING
ZPatterns.
Here my first little problem:
I've a db_sequence specialist who serves the
Framework with
db_id's for new Records like:
newid =
db_sequence.getItem('sequence_name').nextid
The Attribute nextid is provided by a
Skinscript-Method:
WITH getNextId(seq_name=self.id)
COMPUTE
seq_name=seq_name,nextid=_.int(nextid)
"getNextId()" is a PythonMethod and uses
ZSQL-Methods to
compute the NextId while Locking the Table:
PARAMETER: self, seq_name
self.sql_Lock()nid = 1for cur_id in
self.sql_NextIdGet(seq_name=seq_name):nid = cur_id.nextid +
1self.sql_NextIdUpdate(seq_name=seq_name,nextid=nid)break
else:self.sql_NextIdCreate(seq_name=seq_name,nextid=1)
self.sql_Unlock()
return {'seq_name':seq_name, 'nextid':nid} # HERE'S
MY PROBLEM I THINK
I tried to return nearly everything expect a certain instance of a
"special getNextId-Return-Object" e.g. return nid / return (seq_name,nid)
...
I tried serveral ways to reach my return values in the SSMethod:
... COMPUTE nextid=nextid or nextid=self.nextid or nextid=RESULT ...
Finally i tried to follow what happens during a get-call of an Attribute in
the source ..
no success ..
except when i use some Dummy ZSQL-Method which does the following and
works (but this is not the way to do it ..)"select value as nextid,
value as seq_name"
can someone give some advice or enlighten me about the Namespace I'm in, at
SSMethods Attribute providers
atexecution-time ?!?
My Second "little" Problem:
i'm not the first one who had problems to manage data with rdbms and
zpatterns. i can get Attributes through SSMethods
easily and now tried to setup ADD/CHANGE/DELETED Rules to manage
data.
Here my SSMethod for
this(getEventById/insertEvent/updateEventareZSQL-Methods):
WITH QUERY getEventById(id=self.id) COMPUTE
sid=_.int(id),name,time_start
WHEN OBJECT ADDED CALL insertEvent(id=self.sid)WHEN OBJECT
ADDED,CHANGED STORE sid,name,time_start
USING
updateEvent(id=self.sid,name=self.name,time_start=self.time_start)
I access the Item through loadAttribute:
"sid"
I set up a ZClass derived from Dataskin which acts
as Storage-Class.
I call
dtml-let
ni="newItem(key=db.getItem('data_event').nextid)"
nips="ni.propertysheets.get('Basic')"dtml-var
"nips.manage_changeProperties(REQUEST=REQUEST)"/dtml-let
and get back an empty object without any attributes
(propertysheet-problem??)
the record in the database is created (but only
because I reduced the ZSQL-Insert Method to id-parm only)
this again seems to be a Problem of the namespace
I'm in while the _objectAdded() ... method.
- Do I need a PropertySheet when I only want to access/change/create/delete Items/Attributes from a RDBMS ??
If yes: Which one
(CommonInterfaceProp/DataSkinProp)
If no: how do i Access/Change my Properties
??
- and another Question related to
this:
Which object fires the Trigger-Event
(ADDED/CHANGED/DELETED) ..
is it the PropertySheet itself
???
lots of questions still there but these are
thepoints i really tried to get working .. but i did'nt..
hope that there is an answer ..
thanks in advance

[Zope-dev] Custom Unauthorized errors...
With all the work going on related to Zope's authentication system has there been any progress on allowing custom unauthorized errors? I'd refer to the bug id in the collector, but it seems to be down at the moment. I'm planning on using LoginManager which fixes this to a certain extent last I heard... that is it will let you use a customized unauthorized error when you know who the user is (ie. they've logged in), but not for anonymous users. Just out of curiousity (I'm looking at the source now to figure this out, but I thought it couldn't hurt to ask), why is this? The anonymous user has a user object, and so would seem to be a real user as far as the system goes. I'm tired of hacking custom unauthorized errors into zope all the time, so I'd really like to get this fixed at some point. Any thoughts as to directions to go, or dead ends to be avoided. I'll be looking into this as I find time so any help would be appreciated. -- John Eikenberry [[EMAIL PROTECTED] - http://zhar.net] __ "A society that will trade a little liberty for a little order will deserve neither and lose both." --B.

The Attribute nextid is provided by a Skinscript-Method:

I would not suggest using nextid as an attribute. This should really be a method, e.g. getNextId(). The method should then return the result of calling Counters.getNextId(seq_name=self.id).
However, if you insist on using the above approach, your SkinScript should read:
WITH
getNextId(seq_name=self.id)
COMPUTE
nextid=RESULT['nextid'], seq_name=RESULT['seq_name']
Notice that since your Python method returns a dictionary, RESULT is a dictionary, not an object, so you have to retrieve the elements you want in your expressions that way. Of course, you could just have getNextId() return an integer result, and use:
WITH getNextId(seq_name=self.id) COMPUTE nextid=RESULT
WITH SELF COMPUTE seq_name=id
to achieve the same effects.

Here's what you're missing. There is no "sid" attribute when you add an object. You need to add this to your SkinScript (assuming I'm guessing correctly what sid is supposed to be):
INITIALIZE OBJECT WITH sid=_.int(self.id)
Otherwise, your two ADDED triggers will execute with no value for the sid attribute.
- Do I need a PropertySheet when I only want to access/change/create/delete Items/Attributes from a RDBMS ??

Yes. DataSkin Property sheets would be the ones you need to use.
- and another Question related to this:
Which object fires the Trigger-Event (ADDED/CHANGED/DELETED) ..

When you change the attributes of the object, the action is logged for the trigger to fire at transaction commit time. The Property Sheet is just a way to change the attributes.

You *could* return a dictionary from a DTML method:

dtml-return expr={ 'foo' : 0, 'bar' : 1 }
DTML Method 'show_dict'::
dtml-var standard_html_header

dtml-let dict=return_dict
p Foo: dtml-var "dict['foo']"
p Bar: dtml-var "dict['bar']"
/dtml-let
dtml-var standard_html_footer
but I can't imaging wanting to. Try to rearrange your
stuff so that the code generating the mapping can call
'manage_changeProperties()' its own self, or else move
it to PythonScripts/PythonMethods/ExternalMethods/a Product;
you'll be glad you did.

Apache gets a request, passes the request on to Zope, Medusa/Zserver serves up the results back to Apache, which then hands them out to the original requester. And do you need to set both Apache and Zope to have the vhosts (do I need to set up a vhost twice?). In a manner of speaking, yes. That is, Apache needs to have correctly configured VirtualHost directives to handle the requests from the outside world appropriately, and Zope needs to have the SiteAccess product installed with correctly configured SiteRoots and access rules.

You can control the contents of the logs using the LogFormat directive; I use the same format for all of my virtual hosts, but I think you can specify a different log format for each host if you desire.

[Zope] How to remove Items from ZPatterns:Rack in the right way ?
Hi, I have a question about ZPatterns:Rack.
I got 10 items in a Rack and I want to remove those objects.
By reading Rack.py , I know that manage_pack can do this for me if
getItem(key) return None for those objects.
Well, how to return None?
One way I found is that: under "Storage" manage_tab, there is a option:
{Objects are: loaded by accessing attribute [x]}
assign x to be a "non-existing method", ie, any string except those
attributes' names.
Then, by clicking "remove orphaned slot" which triggers manage_pack.
I can see the counter of "Persistent slot in use" was reduced.
The question is that: why it reduced gradually? It doesn't reduce to 0 by
just one click.
I have to click it several times in order to remove all of them.
How does it happens? What's the right way to remove an item from a Rack?
Thanks a lot.
Iap,Singuan

Re: [Zope] VHost logs.
In a manner of speaking, yes. That is, Apache needs to have correctly configured VirtualHost directives to handle the requests from the outside world appropriately, and Zope needs to have the SiteAccess product installed with correctly configured SiteRoots and access rules. It takes a little bit of time to figure out, but it works like a charm and is really quite simple, once you wrap your head around it. There's a great HOW-TO on this at http://www.zope.org/Members/anser/apache_zserver. I would also point you to http://www.apache.org/docs/vhosts/mass.html for more info on the apache side, particularly this bit: The main disadvantage is that you cannot have a different log file for each virtual host; however if you have very many virtual hosts then doing this is dubious anyway because it eats file descriptors. It is better to log to a pipe or a fifo and arrange for the process at the other end to distribute the logs to the customers (it can also accumulate statistics, etc.). Another benefit of this setup is that it can allow for both regular HTTP and SSL connections to all of your sites, so you can remotely access the manage screens without sending your passwords in the clear. A HOW-TO for this lives at http://www.zope.org/Members/unfo/apache_zserver_ssl. I still haven't figured out a clean way to make it impossible to access sensitive areas UNLESS you're using SSL, however. Anyone out there doing this? mod_rewrite is your friend. You just make a Rule that redirects anyone accessing your site on port 80 to port 443, something like this: VirtualHost 123.123.123.123 ServerName www.foobar.com RewriteEngine on RewriteRule ^/(.*)https://www.foobar.com/ /VirtualHost seb ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )

[Zope] mysql zope
Hi Zopistas! we are looking for a method to do a better integration of mysql 3.23.27 with zope 2.2.2. (we are using the Z MySQL database adapter Z MySQL DA 1.1.3.) We have to store data in a mysql database - we can´t use ZODB because we need the data accessible by other programs via ODBC. We habe implemented several ZClasses like "customer", "product" and "orders". We store their instances (eg. each product, customer and so on) to the mysql-database. Our problem: we can´t use the standard ZOPE management interface to manage the objects, because the methods of this interface store content to the ZODB - and not to the mysql-database. Is there a way to extend the standard ZOPE management interface with additional mysql statements? For example: we select an object in a zope folder, press the ZOPE Delete-Button, then this object is deleted on the mysql-database, not on the ZODB? For each zclass (customer, products, orders) we need these extra methods (Delete, Update, Insert ...), so our thought is that we would prefer to use the ZOPE management interface to do this instead of programming "extra methods" which obviously can't be used within the standard ZOPE management interface.

Karim Yaici wrote: Hi guys, I found this article written by someone from Quixote concerning Zope, describing its weaknesses and possible future development http://www.amk.ca/python/writing/why-not-zope.html This guy is quite far up his own arse :-) It's probably more useful to work around the problems he describes rather than bitching about them and telling people not to use Zope: The 'no grep' is probably the most serious of his points. You can easily get around it though, by using a ZCatalog. Admittedly, a decent search and replace interface (which I'm plugging for on zope-dev ;-) would be really nice (Zope 3? ;-) No CVS is also a problem, but with the improvements in the History tab and the like, this less of an issue. Besides, it's again easy to work around by keeping CVS-ish stuff on the filesystem either by putting them in python products or HTMLFiles. There's even ZCVSMixing should you really be pedantic. The test suite stuff is true for any web application, as has been discussed on the XP lists (so I'm told ;-) That said, there's ZUnit and PyUnit now, so I'm not sure that his opinion on this is valid at all. His comments about DTML are all valid, but it's a choice he'd made to write logic in DTML and he's a fool for doing so. IMNSHO, all 'logic' should be kept in python and you should never need to use the "" in a DTML tag. If you do, you're doing too much in DTML. Put it in a product or one of Evan's new-fangled python methods (although these aren't CVS'able, so I'd advise against it, unless is 'python scripting') If used this way, DTML actually provides quite a nice scripting layer for people who only understand/care about HTML, and there's the promise of XHTML for the future. He sees DTML's 'dynamic scoping' as a hinderance, it's actually one of its strengths. Yes, it can be confusing, but maybe you should just write code which doesn't make assumptions about variables, or handles the cases when they're not there. The same is true of acquisition and the namespaces concepts, maybe with better documentation, people like him wouldn't have such problems. Zope's built in FTP server is one of it's huge stengths, IMO. He hasn't realised this and so bitches about it. You can always turn it off you know! Likewise the HTTP server, run Zope as a CGI if you must! :P Oh yeah, TTW editing does _not_ mean code has to live in the ODB as I've already mentioned. Of course, in being behind Quixote, this guy has an alternative motive for slagging off Zope, but I do wish he wouldn't. In (almost) his own words, he just wants a filesystem of python scripts to build his website. Fine, but that doesn't solve a lot of people's problems and has a lot of limitations, hence Zope came into being. Yes, it's a complex beast but, if handled correctly, it'll save you loads of development time and leaves you with a graceful, quick application that is seperately configurable and scriptable, and has a _lot_ of code re-use. I'm pretty sure this is true for the vast majority of web applications but, of course, there are exceptions, although I'm not sure MEMS Exchange is one of them ;-) The one problem with Zope that he _should_ have mentioned is this: You have to try pretty hard to write nasty code in Python, which si why it's so great. Conversely, it's quite easy to build 'nasty' applications in Zope that are messy and hard to maintain. Such is life, that's a possibility I'm willing to live with for the power that Zope gives me. cheers, Chris ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )

[Zope] dtml-tree stuff
I think I may not have asked a specific enough question last time round. I'll try it again. I've been looking through the How-To's and the documentation and the dtml-tree stuff that I have found seems exceedingly cryptic. The closest that I've come to a solution is the following code: dtml-in "getAllClientNames(REQUEST)"dtml-tree id=clientID branches_expr="getClientsForProjects(get_clientID=clientID)" dtml-var company_name/dtml-tree/dtml-in where getAllClientNames looks like: select company_name,clientID from client; and getClientsForProjects looks like: select company_name, clientID from client where deleted = 0 and clientID = dtml-sqlvar get_clientID type=int; This gives me a tree structure which, when I expand company1 gives me company1 again and again (ie Company1 Company1 Company1 Company1 etc as deep as I care to go Company2 Company2 etc Company3 Company4 What I'm trying to do is list my company name as the tree branch and have the sub headings of each branch be my projects for that company. Can anyone help? Thanks very much Mike Kelland [EMAIL PROTECTED]

Re: [Zope] VHost logs.
seb bacon wrote: Rob Miller wrote: In a manner of speaking, yes. That is, Apache needs to have correctly configured VirtualHost directives to handle the requests from the outside world appropriately, and Zope needs to have the SiteAccess product installed with correctly configured SiteRoots and access rules. It takes a little bit of time to figure out, but it works like a charm and is really quite simple, once you wrap your head around it. There's a great HOW-TO on this at http://www.zope.org/Members/anser/apache_zserver. I would also point you to http://www.apache.org/docs/vhosts/mass.html for more info on the apache side, particularly this bit: The main disadvantage is that you cannot have a different log file for each virtual host; however if you have very many virtual hosts then doing this is dubious anyway because it eats file descriptors. It is better to log to a pipe or a fifo and arrange for the process at the other end to distribute the logs to the customers (it can also accumulate statistics, etc.). This document refers to handling situations where you have a very large number of virtual hosts and don't want a separate VirtualHost directive for each one (because they're all very similar). This is not my case, but it could be the original poster's. You certainly CAN log to different log files if you have a VirtualHost directive for each host; I'm doing so. Another benefit of this setup is that it can allow for both regular HTTP and SSL connections to all of your sites, so you can remotely access the manage screens without sending your passwords in the clear. A HOW-TO for this lives at http://www.zope.org/Members/unfo/apache_zserver_ssl. I still haven't figured out a clean way to make it impossible to access sensitive areas UNLESS you're using SSL, however. Anyone out there doing this? mod_rewrite is your friend. You just make a Rule that redirects anyone accessing your site on port 80 to port 443, something like this: VirtualHost 123.123.123.123 ServerName www.foobar.com RewriteEngine on RewriteRule ^/(.*) https://www.foobar.com/ /VirtualHost I don't want to force ALL access to port 443, only certain sections of the site which require authentication to access. I guess the above still holds true (your correction in a later message is noted), I just need to get more creative with my rewrite rules.

Andy McKay [EMAIL PROTECTED] said: The heavy lifting, logic and anything more should be in python. I won't pretend its particularly easy Zope hurt quite a lot some times, but we got there.. I think this is the biggest problem of Zope. Contrary to Python, Zope makes it /hard/ to do things the simple, clean, correct way. The easiest way to add behavior to Zoplications is to add more DTML tags to your web pages; the second-easiest way is Python methods but it's not clear to a lot of people what the calling semantics are; still a bit harder is to write special ZClasses with Python methods that encapsulate your behavior (you can only add ZClasses at one point in the tree, and that's always /not/ the point you are doing all the other work), and the hardest way is to separate stuff out in products (which means, as far as I understood it, hitting lots of "Restart" buttons and certainly means that you loose the multi-versioning capability of ZODB.

[Zope] Finding PARENTS in an external method.
I have an external Method. How do I call PARENTS[-1] from it?
in dtml it would be: dtml-in "PARENTS[-1].objectValues('Folder')"
I have tried something like:
self.PARENTS[-1].objectValues('Folder')
I have also checked if PARENTS get passed to the method like:
myMethod(self, PARENTS=None):
To get a list of the root's Folder's, but no luck.

Re: [Zope] Finding PARENTS in an external method.
PARENTS is part of REQUEST so:
def test(self, REQUEST):
msg = ''
for parent in REQUEST.PARENTS:
msg = msg + str(parent.absolute_url()) + 'br'
return "%s" % msg
Is a convoluted way of listing parents urls...

hi, Max
i tried this and it works. the output is pretty ugly if you return it to
Zope though. maybe someone knows how to clean it up.
def index(self, PARENTS, REQUEST):
n = PARENTS[0].objectItems(['File','DTML
Document','Folder','ListMate','DTML
Method'])
n.sort()
#n.reverse()
return n
this example just sorts the list and sends it back. you can remove the
sorting code. i named this method index_list and called it as such:
dtml-var "index_list(PARENTS, REQUEST)"
