Re: [Zope-dev] how can I stop zope through ftp?
My take is that you won't be able to restart Zope via FTP, but you can do it with a normal URL link. The URL would be http://yourmachine/Control_Panel/manage_restart to restart it or http://yourmachine/Control_Panel/manage_shutdown to close Zope down. Obviously you will need to authenticate in some way, and this depends on what sort of user management you have set up. You could for instance, if using normal web authentication, pass the user/password on the url like so http://user:pass@mymachine/Control_Panel/manage_restart. hth Phil [EMAIL PROTECTED] - Original Message - From: "robert at rocad" <[EMAIL PROTECTED]> To: "zope-dev" <[EMAIL PROTECTED]> Sent: Monday, April 09, 2001 9:41 AM Subject: [Zope-dev] how can I stop zope through ftp? > Hi there, > I am looking for a way to stop zope through FTP. > > Why? > I would like to have a button on my (Windows) desktop I can push to restart > zope without leaving Zopes current setup. > > thanks > Robert > > > > ___ > Zope-Dev maillist - [EMAIL PROTECTED] > http://lists.zope.org/mailman/listinfo/zope-dev > ** No cross posts or HTML encoding! ** > (Related lists - > http://lists.zope.org/mailman/listinfo/zope-announce > http://lists.zope.org/mailman/listinfo/zope ) ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )

[Zope-dev] ZSQL methods seriously broken
Hi there, Type marshalling is seriously broken in ZSQL methods. The bug is a bit subtle, though. There are reports of this in the collector almost a month old, and the severity of this bug is pretty high (could seriously disrupt Zope upgrades to recent versions which apparently have this bug; I don't know when it was introduced), so I'm making some extra noise about it here. First how to reproduce the bug: Create a ZSQL method 'my_method'. Give it an argument: foo:int and some body. Now make a DTML Method, 'test_my_method' Do something like this following: What should happen is a failure of 'my_method'. my_method however happily continues, treating 'foo' as a string. This can lead to subtle bugs; you push in a '0' string expecting the type marshalling will make it a 0. Then you put a somewhere in your ZSQL template, and the condition will never be true, as foo will always be a string. This bug is relatively hard to discover; the ZSQL *test screen* does do the proper marshalling, as the marshalling bits are placed in the test form body (). And of course for most ZSQL methods, you use , which does its own marshalling. I've seen this bug in 2.3.0 and 2.3.1. From collector reports it also looks like default arguments don't work either. I hope the bug is hereby noted by the powers that be. :) The fix is along the lines of using the ZPublisher Converters module in ZSQL methods somehow, I suspect.

What I am watching out for is evidence that adding, indexing, reindexing, or retreiving *a single object* (or a small set of objects), takes longer if there are more objects stored/indexed already. In other words, does the time to store/index/reindex/retreive an object change (for the worse) depending on whether there are 10,000 objects, 100,000 objects or 10,000,000 objects stored/cataloged in the ZODB/ZCatalog? Previously, the fact that searching performance suffered depending on a combination of number of total objects and the size of the result set (irrespective of the batch size, apparently), came to light, and has apparently been fixed. Now searching performance scales with the number of cataloged objects. So, are there any non-linear gotchas waiting for me?

[Zope-dev] ZPatterns Attribute Provider Problem
Hi everybody!
I am trying to write some attribute provider for storing data inside
an SQL table as I am bored of typing parameter lists over and over
again (e.g. in every ZSQL method, in every SkinScript method etc.)
The problem now is that adding a new row to the table (and thus adding
a new object to the rack) is working well but updating an object does not.
Basically the main problem is that _objectChanged is not called in my provider.
What I did is the following:
- If an attribute of the propsheet is changed, _SetAttributeFor is called
and stores it into the cache (as I don't want to update the database for
every attribute change).
- _objectChanged is then supposed to create an sql query and execute it.
This - as said - is actually not happening, as the whole method is not called.
- My namesForRegistration looks like this:
def namesForRegistration(self,container):
""" return names for registration """
return {
'provides':('handlers','attributes'),
'getattr': self._attribs.keys(),
'setattr': self._attribs.keys(),
'delattr': self._attribs.keys()
}
with self._attribs containing the attributes my provider is responsible for.
So is there any reason why _objectChanged is not called? Actually I am a bit
confused when reading the ZPatterns source which should call it.. ;-)
So which are the conditions under which it's supposed to be called?
(_objectAdded() as said before is called actually..)
I hope someone can help me :)
cheers,
Christian

Re: [Zope-dev] ZPatterns Attribute Provider Problem
Well, sorry for mailing to quickly, but removing
_objectChanging() from my class solved the problem. My version simply
wasn't setting the right status to the transaction.
(though I think that I had a reason for adding it some time ago..)
But maybe it's working now.. (but it seems so)

[Zope-dev] Objects, Roles and Permissions
Hello warriors, what's the fastest way to find out whether a specific role has a specific permission on a specific object? What's the fastest way to find out if it's acquired? Even more interesting: How would I find out whether a specific role has a specific permission on a specific object, _taking_acquired_rights_into_account_??? In other words (management screen): "View" permission is not checked for the Anonymous role, but acquired. Therefore the "Anonymous" role maybe _does_ have the permission to "View" this object, through acquisition. Would I have to climb up the ladder manually and check every parent until acquisition has been "turned off", or is there some function - even if it's only available for an external method - that already does this work? I looked through the ZMI pages (and the .py's under "lib/python/AccessControl") but couldn't find anything useful for this purpose. Iterating through permission_settings takes too long and I don't know how to access the specific roles/permissions directly (by name), mainly because mapping constructions like "p199r0" are not very handy...

Re: [Zope-dev] 27 million objects.
Concerning Zcatalog: 1. Search of vocabulary is fully matched, partial search, trancate search or fuzzy search will be useful for searcher. 2. If we catalog all things in one catalog, then we need to make filter when we want to search on one particular portation. 3. I would like to suggest : putting cataloger in branches and make them catalog only those they were interested. for example, if we put catalog in every branch of tree, then they catalog only that branch. catalog can be set to propagate their collection into higher level. This can be done in background. Then a search on a higher level will result in : 1. result in that catalog which meet the search specification and result from the lower level of those the higher level does not known as which match the search specification. In such settings, for example, we can arrange the catalog into multi-layer or have catalog specialize in one section. And have the propagate hierarchical which they update their upper level catalog in batch. The user is allow to search in a level and get all results up to that level and below. for example, in zope.org, we can put catalog in every document level, which catalog one document and one mother catalog which combine all catalogs from every document and one level up to handle all zope site. The we can search specifically in whatever level we want. It seems very difficult for all the catalog hierarchical to share their storage, so there will be some storage inefficent. But this can provide the necessary scalability.

[Zope-dev] ZUserFolder usage and development
Dave, 1. I say sync because UserFolder keeps its objects in an attribute called "data" (list of Users) whereas ObjectManager does not. The 'name' attribute is no longer necessary because I usee the id of the object and allowing it to be specified presents potential discord. 2. Correct, you're supposed to check for that in your constructor, but this is a new Product and could obviously be changed. In fact, I'm thinking of eliminating the constructor params altogether and allowing them to be set later. manage_editUser does check that password and confirm match since in fact it calls the Super. 3. I'm gonna pitch this out. say it all to the benefit of all. Incidentally, great working with you on this. Excellent feedback, and your catchin' on quickly (hooray! another infected by the Zope bug).

[Zope-dev] RE: your mail
Read committed is faster, but I have not done any tests to know how much faster. Read committed mode doesn't support concurrent updates either, but fails silently. In other words, given to concurrent queries: update foo set a = a + 1 update foo set a = a + 2 Assuming these overlap, and a starting value of 0 for "a", read committed mode would result in "a" either being 1 or 2; serializable mode (with my patch) would result in "a" getting set to 3. -Randy > -Original Message- > From: Federico Di Gregorio [mailto:[EMAIL PROTECTED]] > Sent: Monday, April 09, 2001 1:23 AM > To: Randall F.

I whined about this a little while ago under the subject "Determining Acquired Permissions?" on the 26th of March. The standard manage_access doesn't display the actual acquired permissions, just that they are acquired. Anyway, here's a code snippet I use to figure the roles allowed to"View". Feel free to expand the method to other roles and the full suite of permissions. The roles are obtained using self.valid_roles(). The permissions are obtained using self.ac_inherited_permissions(1).

Your snippet worked fine _if_ the view permission was acquired by that object. As soon as I turned off acquisition for the view permission of the object, it would still give me the acquired roles (that in fact were'nt acquired). What does the "if" statement look like that would return the object's own roles for the View Permission if acquisition was turned off? Naive Danny who doesn't know s... tried to put if hasattr(self.aq_base, '_View_Permission'): return self._View_Permission at the beginning of your code, but no effect. :-( But now I see how to access specific permissions and read their content (do I? I'll experiment with it), thank you very much! I will put a string.replace on top and pass the Permission to examine by string parameter, and call that whole stuff "getAllowedRoles". A "getGrantedPermissions" for examining a role should work similarly, right? def ac_inherited_permissions(self, all=0): set all to 1 and then... iterate through the list (tuple or list? list of tuples?) and check every "_current_Permission" if it contains the role? Thx once again, Danny btw: Isn't return['Manager'] at the end of your code obsolete (but safe)?

[Zope-dev] standard_error_message manipulation
Hi, As part of a large python product I wanted to modify the normal "Zope Error" standard_error_message page. Most exceptions will be caught in the code, and therefore those that do get through and cause an error message to be displayed to the user probably indicate a bug in our code. I would like to give the user the ability to submit the details of the exception along with their own information as a bug report. I created my own standard_error_message, and wanted it to contain a form with the values of error_value and error_tb among others. It however appears that the values of these variables get rendered into HTML much earlier than desired and therefore aren't very readable in a bug report. Is there a better approach to this problem? or a work around? thanks -d -- Dyon Balding <[EMAIL PROTECTED]> ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )

[Zope-dev] Image Archive Project (phase 2)
Ok, I now have the following setup: ArchiveImages (Specialist) defaultRack traversal (SkinScript) traversal_method (Python Script) Renderings (Specialist) defaultRack The SkinScript in ArchiveImages/defaultRack simply points __bobo_traverse__ to traversal_method. traversal_method, in turn, checks to see if it is being called with one of a short list of known methods of the ArchiveImage ZClass, otherwise it returns an object in the Renderings Specialist. Which object, you ask? The objects in Renderings are instances of RackImage (a class that subclasses Image and DataSkin). Currently, I have hardwired behaviour that instantiates a RackImage in Renderings when you create an ArchiveImage. Assuming that the ArchiveImage is created with an id of '001', then the RackImage is created with an id of '001_original'. So when the traversal_method is presented with a path of '/ArchiveImage/001/original' it returns the object from '/ArchiveImage/Renderings/001_original'. Thus the ArchiveImage ZClass appears to have an 'original' attribute that returns an image. Here is the traversal_method Python Script: import string if name in ['index_html', 'editInstanceForm', 'editInstance']: return getattr(context, name) else: rendering = string.join([context.id, name],'_') return container.Renderings.getItem(rendering) Ok, so what's next? Somehow, ArchiveImages must be made aware of what Renderings they have. The ArchiveImage Specialist needs a getRenderingIds() Python Script, which in turn calls container.Renderings.getRenderingIdsFor(). Now I'm stuck. How do I select all the Renderings that have (for example) '001' in their id, and return just the second portion of the id (such as 'original' or 'thumbnail')? What do I need to put into the getRenderingIds and getRenderingIdsFor Python Scripts? TIA, Michael Bernstein. P.S. The (currently hardwired) Renderings instantiation code will be delegated later to another Specialist, RenderingDisplays. ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )
