[Zope-dev] Re: Strange security issue with Zope 2.8.1
My understanding (and the way we use it when monkey patching for instance) is that whenevery you apply new security to a class, you create a new ClassSecurityInfo on it. It only defines new stuff to do. The real synthesized security is still stored in __ac_permissions__. Yes, your understanding matches what I know now. Part of my earlier diagnosis was wrong, the behavior of class_init has not changed between Zope 2.7 and Zope 2.8, just the behavior of Archetypes. What Archetypes seems to do is to generate a new ClassSecurityInfo during the call to registerType, which does not contain added information, but information about every single method on the class. It does try to look at the already existing __ac_permissions__ to make sure already set permissions don't get stomped, but when a name is declared private or public it will not be part of __ac_permissions__ and Archetypes will gladly stomp all over it. I have applied a patch locally (and submitted it on the Archetypes bug tracker on sf.net) that seems to solve the problem. I honestly don't know if there are other dangerous consequences because the way Archetypes works is just really dark magic which I don't want to get into too far. Basically, at the point where it tries to find already- set permissions, I am also trying to find a name method__roles__ to determine if something has already been declared private or public, and then re-declare it private or public on the ClassSecurityInfo object that Archetypes creates: Index: Archetypes/ClassGen.py === --- Archetypes/ClassGen.py (revision 6167) +++ Archetypes/ClassGen.py (working copy) @@ -103,6 +103,8 @@ perm = _modes[mode]['security'] perm = getattr(field, perm, None) +method__roles__ = getattr(klass, '%s__roles__' % methodName, 0) + # Check copied from SecurityInfo to avoid stomping over # existing permissions. if security.names.get(methodName, perm) != perm: @@ -112,6 +114,10 @@ 'permission declared is the correct one and ' 'has preference over the permission declared ' 'on the field.' % methodName) +elif method__roles__ is None: +security.declarePublic(methodName) +elif method__roles__ == (): +security.declarePrivate(methodName) else: security.declareProtected(perm, methodName) jens ___ Zope-Dev maillist - Zope-Dev@zope.org http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )
[Zope-dev] Strange security issue with Zope 2.8.1
I have found a strange security issue with Zope 2.8.1 that seems to stem from code not doing what it was supposed to do in Zope 2.7.x, but which works in 2.8.1 and then causes other side effects in code that relied on the broken behavior. Symptom: In Zope 2.8.1 it is *impossible* to override a ClassSecurityInfo security declaration in an Archetypes-derived content item. (I have a small set of unit tests that proves the behavior under Zope 2.8.1 if anyone is interested) A little background: When you register an Archetypes-derived content type, it will do all the generated accessor/setter method magic and then call InitializeClass a second time. The code in lib/python/App/class_init.py has changed between Zope 2.7.x and Zope 2.8 in order to support new-style classes. To be more precise, instead of manipulating the class __dict__ directly we now use setattr/delattr/etc. This change seems to have un-broken code which did not do what the code comments suggest. Namely, when a class is sent through class_init.default_class_init__ (better known as Globals.InitializeClass) the class __dict__ is searched to find objects that look like ClassSecurityInfo instances in order to read and apply the security settings. After finding the ClassSecurityInfo instance, it is force-deleted from the object (the comments say, out of paranoia). However, somehow this did not work correctly in Zope 2.7.x, where the deletion call looked like... del dict[key] (dict being the class __dict__, and key being the name of the ClassSecurityInfo instance). Under Zope 2.8, it looks like this: delattr(self, key) (self being the class object). Under Zope 2.7, the security object *would still be there* when hitting InitializeClass for the second time via Archetypes' registerType, which in turn meant Archetypes would not instantiate its own ClassSecurityInfo instance and stuff it with the declarations from whatever Archetypes-derived base class you used. In Zope 2.8, the deletion actually works as intended - but due to that fact Archetypes will instantiate its own ClassSecurityInfo and populate it with the declarations from the base class that I am trying to override. So the overridden settings are all overwritten again by the base class declaration. My question is, what is the reasoning behind deleting the ClassSecurityInfo object from the class after it has been read the first time? How can this be implemented in a sane way so that custom security declarations can be retained? jens ___ Zope-Dev maillist - Zope-Dev@zope.org http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )

From my reading of http://www.apacheweek.com/issues/02-10-04 this issue only existed in 1.3.26: In 1.3.26, a null or all-blank Content-Length triggers an error although previous versions would silently ignore it and assume 0 length. 1.3.27 restores this previous behaviour. The other content-length-related issue actually seems to imply it is better to leave the header out of 304 responses, because Apache would mis-use the header and apply its value to cached content: Some fixes to mod_proxy. The cache was incorrectly updating the Content-Length from 304 responses when doing validation. Also fix a problem where headers from other modules were added to the response headers when this was done in the core already. Also OFS.Image been patched as of Zope 2.7.1 [2] in such a way that it would have already tripped a combination of old-ish Apache and new-ish Zope. Though ZServer was still throwing in a Content-Length: 0. (Which I read as sufficient to provoke the bug in Apache 1.3.27.) Yes, both issues mentioned above actually, from the way I read that text. This setting could be manipulated via a zope.conf directive, but from the evidence it seems the maintenance/administrative annoyance of adding yet another knob for something that seems to carry no risk might not be worth it.

If it's the latter, maybe as devil's advocate, I need to ask what the point is here? It came across the same way for me. Not only we Z3 people will go along on our merry way, let the Z2 people deal with the problems, it's also about bundling a version of Z3 that is apparently not within the Z3 developers' path anymore (at least from the description). I didn't answer until I read Chris' post because I work on CMF when I work on Zope, so I don't do much as far as checkins to Zope goes. He says what I only thought, and I had the same thing in the back of my mind: If this becomes an obstacle I just won't touch it anymore. Yes, I will get into Z3 at some point myself, but preferably at a time of my own choosing... It appears there is an assumption that merging Z2 and Z3 code within Z2 itself is an unmitigated good thing, but IMHO, each is complicated enough in their own right that I'd personally prefer to be dealing with one or the other at any given time and not both. This isn't exactly idle whining either, I need to do this when I maintain Z4I code, and it's definitely not a walk in the park; it's moderately difficult to do and also difficult find people who have the skills to help too. Right on. Now, I have no idea how similar or different the Z3-Z2 marriage in 2.8 is to that unholy alliance that is used for Z4I, but working on it for Z4I is an exercise in frustration every time I had to do it. jens ___ Zope-Dev maillist - Zope-Dev@zope.org http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )
Re: [Zope-dev] encrypted _ac_name _ac_password
The easiest way to solve that is to let the cookie be only a random ticked. That way the userame and password is only sent when actually logging in. This gives as much security as your solution, but it's easier to implement. PluggableUserFolder does, and I think PAS does it do (or at least it will do that soon). PAS can do it currently by e.g. combining a CookieAuthHelper with a SessionAuthHelper. The CookieAuthHelper only intercepts the initial login page and gets the credentials (it does not set a cookie), and only the SessionAuthHelper is called as a CredentialsUpdater - the credentials thus end up in the session and the standard sessioning cookie is the random ticket. jens --- Jens Vagelpohl [EMAIL PROTECTED] Software Engineer +49-(0)441-36 18 14 38 Zetwork GmbHhttp://www.zetwork.com/ ___ Zope-Dev maillist - Zope-Dev@zope.org http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )

Re: [Zope-dev] Zope and Python 2.4
However, RedHat have now released Python 2.4 in the Fedora development stream and it will ship with FC4. Does ZC have an official position upon this yet? Speaking as Zope release manager but not as official of ZC: Python 2.3.4 will likely be the recommended Python version for Zope 2.7. I am personally running Zope 2.7.3 with Plone since some weeks under Python 2.4b1 but I am doing this at my own risk. Python 2.4 might be of interest for Zope 2.8. Going for Python 2.4 just because Fedora ships with it is not really an argument. Add to that the fact that it is *not advisable* most of the time to use the Python interpreter that comes with the system. The reasons have been laid out before, like the fact that the interpreter is most likely compiled with strange flags, and that updating a system-level Python with vendor-supplied packages can have bad consequences for your Zope install. The vendor-supplied Python is (probably) tested with vendor-supplied packages that use it, but certainly not with third party software such as Zope is in this case. jens ___ Zope-Dev maillist - [EMAIL PROTECTED] http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )

Re: [Zope-dev] Re: any limits on object number?
Even using BTreeFolder to store all objects I was getting 300s delay to show a single object (ok, it's an archetypes-based one, containing 50 fields, splitted into 7 schematas, with lots of fancy stuff...). So I made a directory hash structure based on UID from each object (an AT UID is md5, so we have a hex base). My own experience with BTreeFolder2 does not support your diagnosis. I do not believe BTreeFolder2 is the problem here. On a CMF-based CMS that I helped develop the largest BTreeFolder2-based containers held ca. 60,000 items at the top level, meaning we did not use a directory structure to restrict the number of items per folder. There was zero delay retrieving singe items and even stepping into the ZMI where it shows 1000 ids at a time was sub-2 second response time. jens ___ Zope-Dev maillist - [EMAIL PROTECTED] http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )
Re: [Zope-dev] any limits on object number?
When we tried to upload objects from wikipedia's sqldump of after about 40,000 objects in a folder the script went for a toss. roughly each time we ran the script the same problem. even to visit the folder of even 1000 objects through ZMI is a pain. I think that is where BTreeFolder2 will be very useful. Your observations make sense in the context of the standard Zope folder. BTreeFolder2 will help. I am assuming whatever script you use to populate the folder(s) commits the transaction ever N objects, right? I am also thinking to use a squid cache style of storing objects in zodb, where the objects go into many subfolders (i dont know what is this method called technically) with several sub folders with names alphabetized/numbered. this way i can store large number within zodb though not in the same folder/BTreefolder2. Should I use both methods? I would definitely use the subfolder method. Not related to Zope, but what about filesystems? there must be a limit on the number of files within one folder depending on which filesystem one uses. The ZODB, in case you use the standard FileStorage, is one monolithic file. So there is no large number of files on the server file system regardless of how many objects you store. For files on the file systems your choice of file system depends not just on the number of objects but also its size. To re-use your earlier example of Squid cache files, which are numerous and mostly small, ReiserFS is normally recommended. It deals much better with large quantities of files in one folder. jens ___ Zope-Dev maillist - [EMAIL PROTECTED] http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )

Re: [Zope-dev] AW: Caching prob with AHCM and headers
I know, I was just trying to figure out how this was supposed to work. Currently setting Last-Modified seems to be the only way to get something cached in Apache; Expires alone is no good, and adding an Etag header doesn't seem to have any effect either. Maybe this should be classified as an Apache problem? Shouldn't Apache cache pages that have Expires? Please keep in mind that **Apache is not a cache server**, it has caching attached more like an afterthought to the mod_proxy. If you want predictable caching you will need to use real caching software such as Squid. I personally have moved away from Apache even for small websites since there are some other issues with Apache caching, such as zero-length responses in some cases. jens ___ Zope-Dev maillist - [EMAIL PROTECTED] http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )
Re: [Zope-dev] Very severe memory leak
Well, to at least reduce the immediate pressure, why don't you throw more RAM into that server? Memory is cheap. jens On Friday, Aug 22, 2003, at 17:38 US/Eastern, Leonardo Rochael Almeida wrote: Hi, For a long time now, one of our clients, running Zope 2.5.1, has been experiencing memory leaks. For a time this has been relieved by restarting Zope every day at 4am. Lately this was not enough, however, as Zope started taking more and more memory, to the point that it frequently required more than one restart during the day. The machine this is running on is a Xeon 500 MHz with 512 Mb of memory. Zope is a very memory intensive application, but 512Mb used to be enough for a medium sized portal. This Zope site makes very heavy use of both ZClasses and ZCatalog, and it appears to me that this worsening of perfomance and memory consumption was being caused by the increase in content, which caused an increase in the size of the ZCatalog and in the number of ZClass instances. A total of 6796 ZClass instances representing News Items are cataloged. There are other ZCatalogs and ZClass instances representing calendar events and other stuff (this is a very old Zope portal coded by hand in ZClasses, no CMF, no Plone, not even Pagina1, our ZClass based CMS) Fiddling with the cache parameters in the control panel showed that while we could keep the memory consumption to a point where the daily restart would be enough (say, with 10k objects per thread), we would get constant thrashing of cache objects, specially DateTime objects due to the ZCatalog queries, and the machine performance would be close to intolerable, whereas if the cache parameters where set to allow a fast performance (with 50k objects per thread) the machine would run out of memory in 3 to 4 hours. Needless to say this was with heavy use of RAMCacheManagers, not counting the accelerator proxy in front of it. Without the RAMCaches, the machine would go down in under 5 minutes of work hour load. Even with the caches on, the load would never go down from 2.0 during work hours. Last tuesday we decided no longer to wait for 2.6.2 and migrated the site to 2.6.1. We dealt with the ObjectManager-based-ZClass issue, reformed the ZCatalogs to replace the DateTime FieldIndexes with DateTimeIndexes and then had a working testing environment, which we stress tested lightly without detecting any problems and quickly moved to production. This was late at night The next morning we were surprised to notice the machine very quickly ran out of memory. The memory leak was *far more severe* than before. Zope needed a restart every 15m or so before it would send the machine into heavy swaping. In a very non-intuitive hunch I suggested we shut down all RAMCaches and, amazingly enough, this made the situation a bit more manageable. We're now restarting every 45 minutes. To our relief, disabling the RAMCaches had only a barely noticeable effect on performance. The site kept churning out pages really fast, a testatment to the optimization job done in the 2.6 series. The load on the machine is rarely above 0.8, except when it goes into swap :-) The number of DateTime refcounts in the Control_Panel, although much smaller than in Zope 2.5.1 is very high and, mostly importantly, constantly increasing, as far as I can tell. After 12 minutes of uptime, the top refcounts are: DateTime.DateTime.DateTime: 96168 BTrees._IOBTree.IOBucket: 43085 BTrees._IIBTree.IIBTree: 40400 BTrees._IIBTree.IIBucket: 23696 OFS.DTMLDocument.DTMLDocument: 23190 BTrees.OIBTree.OIBucket: 14582 BTrees._IIBTree.IISet: 12479 BTrees._IIBTree.IITreeSet: 10823 BTrees.OOBTree.OOBucket: 7088 OFS.Image.Image: 6860 OFS.DTMLMethod.DTMLMethod: 5894 DocumentTemplate.DT_Util.Eval: 3250 OFS.Image.File: 2796 BTrees._IOBTree.IOBTree: 2761 ZClasses.Method.MWp: 1592 In time, DateTime refcounts eventually dwarves the second place by an order of magnitude. I think this is related to the fact that DateTime instances are stored as metadata, even though the date indexes have been converted to DateTime indexes. The question is, why aren't those instances being released? What is holding on to them? I tried installing the LeakFinder product but discovered it didn't work before stumbling in a message in the archives that told me exactly that :-) The RefCounts view in the LeakFinder object fails with the following traceback: Traceback (innermost last): [...] Module DocumentTemplate.DT_Util, line 201, in eval - __traceback_info__: REQUEST Module string, line 0, in ?

Re: [Zope-dev] LDAPRoleTwiddler / BasicUserFolder
being explicit is almost always better. you are relying on internal magic and it's not apparent from looking at the code you wrote. the validate implementation in the LDAPRoleExtender is the most correct one. shane worked on it for a while to make sure it does the most correct thing possible, and if anyone knows about the vagaries of acquisition/security and all its possible permutations it is him. jens On Thursday, Oct 17, 2002, at 08:37 US/Eastern, Dirk Datzert wrote: Hi Jens, why is that code no longer referring to the real userfolder anymore? it should not make calls to authorize/identify/authorize on self but on the LDAPUserFolder it is using as the user source. self.identify() should be the same as if getLUF().identify() since LDAPUserFolder and LDAPRoleTwiddler both inherited this from BasicUserFolder. self.authenticate() does a self.getUser() which refers to getLUF().getUser() and does twiddling in one step and return the right user-object which the API would expect.

Re: [Zope-dev] Debugging conflict errors? Hints please!
conflict errors do not imply conflicting writes by definition. there is
a thing called read conflict, which is probably what happens to you.

Hi All!
I am experiencing a lot of 'ZODB conflict error at ...' that I can
reliably reproduce by hitting my browser's Refresh button at a high

supposed to change anything in the ZODB but only display results of
some SQL queries. My question is now how to find out what actually is
causing the conflicts. The log entry refers to the page being served
('/very/long/path/detail_view').
As a matter of fact I am not even sure whether the log entry means
that the 'detail_view' document has changed (which of course it
hasn't), or something along the traversal path caused a ZODB write.
Zope 2.5.1, ZEO 1.0
Any hints on how I could find the culprit appreciated.

Re: [Zope-dev] find unused objects: hopefully the last misunderstanding...
extremely expensive. you would have to... - assemble a list of all objects IDs in the ZODB and then... - parse all contents of all objects and check against that ID list. you would probably need a little counter for every single ID that gets incremented upon finding its ID referenced, and all those that are left over with the counter at 0 in the end would probably be candidates for removal. this schema will fall down the moment your object IDs are not unique across the whole ZODB. besides, every object is potentially different in how you access and read its contents. if your whole intent is to have a cleaner ZODB and there is no pressing reason to do this cleanup, i would just forget about it. jens On Friday, Aug 30, 2002, at 07:48 US/Eastern, [EMAIL PROTECTED] wrote: * Starting at root, check all objects if they are referenced, * and produce a list of those which are not, for cleanup purposes. * Packing the database cleans up in this manner.

Re: [Zope-dev] limit to number of operations in a transaction?
in your script you must commit a transaction once in a while with get_transaction().commit(). when you use xml-rpc then every call to zope will end up being its own transaction and you will not have this problem. jens On Sunday, Aug 25, 2002, at 10:12 US/Eastern, Christopher N.

The old format uses Folders and Properties to store information about a person. Name, phone, email, address, etc. The new format uses a Product that I wrote which stores said data in a ParsedXML document. I have roughly 1,500 people in the database. I wrote a script to migrate the people. Basically it does getProperty for each property on each person folder, then creates the new person object which uses XML. Zope apparently cannot handle this number of operations in one transaction. Zope gets slower and slower and eventually becomes on responsive. It looks like the script has completed, but nothing is ever committed to the ZODB, and since Zope is unresponsive it must be restarted. This, as expected, kills that entire transaction which was never committed. Is it known that large numbers of operations, such as above, in a single transaction can cause problems? A transaction, of course, being a request, and an operation being something like manage_addProduct. I've solved the problem by using xmlrpc and for person in people calling my migrate_person script for only one person at a time. This is SO MUCH FASTER. I previously ran the script that migrates all of the people, and after 8 hours it still had not completed.
