Hi Jeff - Thanks for reporting this. It turns out that there was a missing security assertion in the product dispatcher (manage_addProduct) that was causing this. The fix will be in b4. If you want to patch your install in the meantime, edit lib/python/App/FactoryDispatcher.py and change: class ProductDispatcher(Acquisition.Implicit): " " def __getitem__(self, name): ... to: class ProductDispatcher(Acquisition.Implicit): " " # Allow access to factory dispatchers __allow_access_to_unprotected_subobjects__=1 def __getitem__(self, name): ...

Getting at Zope (Version) Transactions
by Darin Lee 29 Jun '00

29 Jun '00

Hail Zopistas, I would like to develop a "what's new" method that parses/accesses the undo transactions list for certain documents so I can post basic information about when they were added, updated etc. in a DTML method for display on my index page. This would also come in very handy for a file-archive system I am planning on building. (I'm talking about the info that shows up when you hit the "undo" link in Zope manager). Is there a way to get at the transaction data? Is this data stored after a version is merged back into the main ZOBD? What would be the best way in Zope to parse this log for certain types, and generate a DTML method? Does Zope support Regular Expressions? I hail from the Perl coders guild (where generating and parsing text/sql is a relatively easy, albeit messy, task) - but am new to Python and OOP in general. However, now that I have Zoped, I can see there's no turning back. Any help would be greatly appreciated! -Darin Lee Darin M.

Urgent problem: Database and large clock skew
by Jim Flanagan 29 Jun '00

29 Jun '00

Hi, In trying to fix a problem with Zope httpd server sockets getting wedged in TIME_WAIT state, I set my system clock ahead by a year, then set it back. Unfortunately, connections to the Zope httpd server occurred while the clock was set in the future, and now when I try to start Zope, it dies with: DatabaseError: The database contains records, starting at position 189587919, that have time stamps 2540023.19965 seconds in the future. This could lead to database corruption. Please double check your system clock! I'm using a pre-2.0 version of Zope (Though I can't determin exacly which version...) Is there any way to correct insane timestamp values? I'm pretty much dead in the water. Alternatively, I have found the section in BoboPOS.py where this exception is generated. Is it really a problem to have future timestamps? What if I just snipped this portion of the code out? Please respond to jimfl(a)tensegrity.net. TIA -- Jim Flanagan jimfl(a)tensegrity.net http://jimfl.tensegrity.net

The tech that does backups on my new NT server (IIS) tells me that everything backs up ok except the \var\Data.fs.lock file. Is that normal or a problem? Darren Addy Internet Specialist and Interim Web Presence Coordinator Office of Information Technology Services University of Nebraska at Kearney

Adding Products Breaking Zope
by Craig 29 Jun '00

29 Jun '00

My co-worker and I are having difficulty adding a few products to our site without breaking Zope. Here is what is happening - after installing the product in the zope directory and reatarting Zope, the site asks for a username and password (when it shouldn'). Not even the superuser can log in. The same is true for the /manage area. All of a sudden, the site is not accessible and the only thing we can do is remove the products from the Zope directory. My problem is with SiteAccess 1.0.1 with Zope 2.1.6 on Debian Unstable (Woody). Is it simply that this version of SiteAccess was written for an earlier version of Zope and is no longer compatible? Or am I just doing something wrong? Later, -- \ Craig "Cowboy" McDaniel /_\ Software Engineer /_/_\ Internet Tool & Die /_/_/_\ craig(a)tool.net /_/_/_/_\ (502) 584-8665 ext 108

Re: Zope won't let me call aq_parent in ZWiki?

Hi Curtis, Sorry for the late reply, I've been on holiday :S Curtis Matthews wrote: > > I've just recently noticed I'm not able to call the JumpSearch and > RecentChanges methods in the Basic ZWiki because I'm not authorized to call > a method called aq_parent. Has anyone else had this problem, and is there a > solution? This is a 'feature' of ZWiki according to Simon Michael, it's author, I think it's a bug ;-) Basically, ZWiki Pages (RecentChanges is a ZWiki Page) execute DTML contained in themselves with the 'Anonymous' role, supposedly as a security precaution. This means that 'Anonymous' must have the 'Access Contents Information' permission for RecentChanges and several other things to work. This makes it practically impossible to have a Wiki that is secure :/ This is a hard problem to solve, see Jim Fulton's server side trojan stuff for a detailed discussion. I don't like the current solution, it's confusing. A better, but not best ;-), solution would be to make ZWiki pages execute with any proxy roles they have and only those roles, or even have a seperate 'This Wiki Page has these roles' configuration box. A workaround would be to make RecentChanges a DTML method rather than a ZWiki page. You should just be able to copy and paste the contents. HTH, Chris

[Newbie Question] Pertaining to Search Engines
by Eddie Mosier 29 Jun '00

29 Jun '00

Is it possible for you to get a site that is built with zope to be found by search engines (other than those that are directory listings, like yahoo.com and dmoz.com)? From what I have seen, I think zope would do what I would like, but I need to know this. From what I have learned so far I doesn't really seen possible. Eddie Mosier
