[Zope-dev] Sessions and long requests = conflicts? Mcdutils?
Hi
Currently I have some problems with our application (Zope2.8.4)
and with Conflict Errors in sessions.
In general if we have few concurrent requests that are running
sometimes for 3-4 minutes (and they're touching session inside)
I get a lot of conflict errors with Inceraser, OOBTree, Length2 etc.
These are errors like:
serial starded with xxx serial currently commited
Of course I know that it is best to move such long processes to
something external with Async, lovely.Remotetask or built
in Oracle jobs, but so far I have to deal with this state of
our application (as I'm not the author ot this but rather
something like an zope admin/supporter for this app).
I think that ConflictErrors are caused because of sessions
implementation, especially: timeslices, current bucket etc.
as written in Transience/HowTransienceWorks.stx.
Changing session_resolution_seconds to big value
helps here. By default we had session_resolution_seconds
set to 300.
I wonder how this happens. If I have two requests that at the beginning
modify it's sessions like: session.set('aa', 1), and then call long
running ZSQLMethods then (if meanwhile timeslice has changed because
of too short session_resolution_seconds):
- first request that finishes finds that there is new 'current' bucket
and moves it's session object and second request's session object to
new 'current' bucket and commits this
- second request finishes and finds that it's session object is not
the same as it was at the beginning (because it was moved to 'current'
bucket)??
Anybody can say if I'm right here?
I also tried Faster product to manage sessions but this behaves in a
similiar way (I mean causes conflict errors in such situation).
I found 'mcdutils' too. Tres Seaver said on zope-dev (a long time ago)
that it is supposed to have no conflict errors:
http://mail.zope.org/pipermail/zope-dev/2006-May/027555.html
Mcdutils:
http://agendaless.com/Members/tseaver/software/mcdutils
There is only 0.1 version. What is it's current state? Seems to
be dead? Can I take a look at this or is this better to not
even touch that?

You could keep experimenting with values to reduce the chances of
conflicts. Perhaps sessions that last for days. With resolution of
hours. Disabling inband housekeeping.
Note that a session-timeout-minutes of 0 enables a slightly different
approach which has a little less active structure.

I don't think session mechanics operates like that at the end of a
transaction. More generally what is happening is that the second
transaction is trying to commit data that was changed by an earlier
transaction after second transaction read that data. In this case the
data is various bits of the internals that make up sessions and
transience storage.
Very careful use of explicit transaction commits may be all that you
need in your application. For example, make all your edits of the
session data early in the request and then commit the transaction.
Then proceed with the longer operation. Might be that destroys the
consistency of your application data though.

'mcdutils' is in a worked for me under light load state; I never
ended up deploying it in production. Because it is not based on the
ZODB, it is certainly not going to raise any ZODB conflict errors.
However, using memcache as the only backing store for your data is *not*
a recommended practice by the memcache developers: they designed it as
a *cache*, not an atomic storage. I dropped further development on it
once I evaluated the cost of having session data disappear (or become
inaccessible) when new memcache servers were added, or old ones removed.
I *do* use 'faster' in production, with the session storage mounted
across ZEO (a configuration which nobody in their right mind would do
with the standard session storage). Some conflicts are possible in the
default configuration, although I never see them in practice at the user
level. However, that applicaiton does *not* set up multiple
long-running transactions which attempt to mutate the same session data.
If you are *sharing* mutable session data between multiple long-running
requests, and expect to have no conflicts, you are in for a
disappointment: unless your application can supply resolution logic,
you *want* conflict errors in such cases.
If you believe that 'faster' is raising conflicts due its own internal
data structures (OOBTree bucket splits), rather than in the
application-dveined session data, there is a conflict-free alternative
available: we found that it was slower than the other, and therefore
didn't scale as well, even given the possibility of conflicts.
To enable the conflict-free storage, you need to patch the
'_BUCKET_TYPE' class-level variable of the storage to use
'AppendOnlyDict' rather than 'OOBTree'. E.g.:
from Products.faster.sessiondata import CBSessionDataContainer
from Products.faster.appendict import AppendOnlyDict
CBSessionDataContainer._BUCKET_TYPE = AppendOnlyDict
I had actually meant to make that a zope.conf-tweakable setting, but
never got around to it.

[Zope-PAS] struggling with Local Role plugin
Hi, I have what I think is a fairly simple use case for my Plone site. I want to be able to add a local role dynamically based on two factors - the content of the object, and a given external condition. So I've written a local role plugin, where getRolesInContext() checks these two factors and returns either an empty list or a list containing one item - the new role. This seems to work well. It's the checkLocalRolesAllowed() method I'm having problem with. My logic looks like: if object has specific content: if external condition is true: return 1 else: return None return None From looking at the PlonePAS code, it appears that the PloneUser class iterates through all of the LocalRole plugins, and continues until one of the plugins returns something other than None. But what happens is that the user is still denied access to the object. If I change the last return to 1, the user can access the object, but naturally gets access to everything else as well. Am I missing some basic logic here? Thanks, Stan McFarland ___ Zope-PAS mailing list Zope-PAS@zope.org http://mail.zope.org/mailman/listinfo/zope-pas

Thanks, Kapil. I'll give it a try. I have a feeling I may be wasting my time
anyway, as I don't see any way to have the dynamic roles be applied for catalog
queries. In other words, if I have object A and object B in the same folder,
and user1 can access object A but not B based on the external condition, user1
should see A but not B in a folder listing, search, navigation, etc. Is there
amy way at all to implement this functionality?

Kapil, I'm close. My goal is to make objects inaccessible if the user doesn't
have the correct dynamic permission. So for objects that the user can't see,
they have no view permission. For objects that they can see, the user gets a
role called DYNAMIC with the view and access contents information
permission. Using your script, I see the following:
roles context ['Member', 'Authenticated', 'DYNAMIC']
access contents 1
view 1
But if I add the following line to your script:
print title, context.Title()
Verbose Security reports the following:
Access to 'Creator' denied ... Access requires one of the
following roles: ['DYNAMIC', 'Manager', 'Owner', 'Reviewer'].
Your roles in this context are ['Authenticated', 'Member'].
What am I missing? Is there some other object that is being accessed, or is
there some other permission other than 'View' and 'Access Contents Information'
that needs to be given?
Thanks very much for your help!

Wichert Akkerman [EMAIL PROTECTED] writes: Use a dynamic group. Wichert. Wichert, Thanks for the response. I can see where there's some similarity in the notion of adding a role to a user dynamically and adding a user to a group dynamically, assuming that the group has the requisite roles. But my problem (and maybe I wasn't clear about this before) is that the condition that determines access is based on both an external condition and an attribute of the object itself, which is why was trying to make this work with local roles. I didn't think that the object was available from the role or group plugins, but if I'm wrong, please let me know. Actually, maybe I should rephrase my problem, and see if you have a suggestion. Basically, I need to set up a security model such that access to a given object requires a combination of roles. For example, I might have an object that would be labeled Alpha, Beta, Gamma, and a user must possess, at a minimum, all three roles to be able to see the object. I could implement this with 2**n - 1 roles, so I would have 7 roles and a separate workflow state for each role - not too bad. The problem is one of scale - if I have 6 labels, I end up with 63 workflow states. So instead, I was trying to use the labels as object attributes and adding roles at runtime. Does this make sense? Any advice you could give would be greatly appreciated. Thanks again, Stan ___ Zope-PAS mailing list Zope-PAS@zope.org http://mail.zope.org/mailman/listinfo/zope-pas

I just need a fixed string search, returning the name (maybe the path too) of the object inside the ZODB, so I can later edit. Is ZMI the right tool to do simple editing? No. The ZMI is an administrative interface. It's not meant to build end user interfaces upon it. Also is ZCatalog already included in Zope, or do I need to install it? Sure it's in there. You can see it as ZCatalog from the ZMI Add menu in the upper right corner.

Re: [Zope] Z Search Interface returns numbers
When I search something in the SearchForm (via the test tab) I just get numbers. I mean the ReportForm correctly reports the objects containing the searched string, but lists handles (I guess). You missed a step: you must use the Metadata tab of the ZCatalog to define which fields of the indexed objects should be returned with the results from the search. After you do that, you'll have to update the catalog (Advanced tab) and then regenerate your search interface. For instance, to return the ids of the objects, add id as a metadata. If you'd like to show the URL of each item, there is no need to set metadata for that, since the records returned form the catalog have a method called getUrl which gives you that. So you can use record/getUrl, where record is the variable name used in the tal:repeat statement which invokes the catalog search results. Thanks a lot, it works! I ended up using getURL metadata, because it's simplier for me.

You are dead right, I'm digging into Plone too, right now.

[Zope] xmlrpc error handling
In order to avoid zodb implosion, is it sufficient to raise an xmlrpclib Fault object from a method where some validation was not successful? Will zope abort transactions and avoid an other avoidable bad things from happening? Do I have to use fault or can I raise just any error an ZPublisher.xmlrpc will marshall it into fault/fault? from xmlrpclib import Fault SomeClass(SimpleItem): ... def myMethod(self,stuff=[]): if type(stuff) != list: f=Fault f(27,stuff must be a list) raise f else: print stuff Thanks, Kevin ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

Will zope abort transactions yes. and avoid an other avoidable bad things from happening? as long as your application is designed well with regard to transaction boundaries, you'll be fine. Inconsistencies could arise if your app does something weird like manually commit a transaction and start a new one before the exception is raised... Do I have to use fault or can I raise just any error an ZPublisher.xmlrpc will marshall it into fault/fault? The latter. Try it and see :) AFAICT any uncaught exception will be published as an xmlrpc fault. But then I think you don't have control of the fault code, if you care about that. -- Paul Winkler http://www.slinkp.com ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

Catherine E. Reinehr wrote at 2007-4-10 20:01 -0500: I've been working in a version for over a week and finally finished my changes today. I saved them and quit the version, but the affected folder still has a lock on it. I've tried four times now to save my changes, and it's just not working. The first time, it seemed to publish the changes but the folder was still locked. On later tries, I encounter an error when I try to access the page after saving changes. Any suggestions? When the ZODB 3.2 code has been restructured (previously, it was tense and efficient but very difficult to read) some bad bugs have been introduced affecting the Version handling. Maybe, you are using such a ZODB version. In this case, searching old mailing list article may come up with some information on how to fix your problem. -- Dieter ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
RE: [Zope] Problem with using versions.
Okay. I'll see about upgrading to 2.10.3 and check out that web site to read up on versions. I think what I may need to do is just recreate my changes outside of the version, which of course will take longer, but at least I won't risk losing anything. I had no idea versions were so buggy; I wouldn't have used them in the first place if I had. :/ Thanks, all, for the help; I really appreciate it! Cathy - Catherine E.
