NTUserFolder still useful?
by Sean Dunn 17 Oct '05

17 Oct '05

I'm running Zope on WindowsXP with plans to run it on server 2003. Instead of creating user accounts I'd like to leverage NT authentication.. And NTUserFolder looks like it might be what I want, except that it looks like a dead product. Besides a note that it works on Win2k under certain constraints, I'm not sure if I should try using it. Have people had success installing this on WinXP/S2003? Thank you, Sean - Sean Dunn Tools Programmer Troublemaker Digital

ZSQLiteDA 0.3.3 probs on zope 2.7.6? Upg. to 2.7.8.
by Petri Savolainen 17 Oct '05

17 Oct '05

Just a report & workaround fyi for anyone running into the same problem: I created a db consisting of a single, fairly small table (4 fields of short strings & a few floats) and imported a large amount of data into it (over a million records). Added a few indexes. The db size is about 440MB. Upon trying to access the data, my sql methods puked - got some memory errors sometimes, sometimes there was something wrong with a "query" variable or something. I did not dig deep on those. Alas, upgrade to Zope 2.7.8 seems to have solved the problem. And there was much joy. Cheers, Petri

zope.conf read-only settings
by Steven Hayles 17 Oct '05

17 Oct '05

AFAICS the directives zserver-read-only-mode and read-only-database just set the environment value ZOPE_READ_ONLY and no change in ZOPE's operation results. Am I right? This is ZOPE 2.7.7 Setting read-only in the database storage does make a difference (in my configuration, Formulator 1.6.2 throws an exception, but that's not a ZOPE issue). Steven

Don't see what any commented block stuff has to do with it, what would that have to do with co_filename? I don't see any real sticking point other than that both CMF and Zope need the changes... cheers, Chris -- Simplistix - Content Management, Zope & Python Consulting - http://www.simplistix.co.uk

REQUEST not accessible
by Jürgen Herrmann 16 Oct '05

16 Oct '05

hi all! i have several products using PageTemplateFiles a lot. up to some time in them i could just write: tal:define="results python:here.Catalog.searchResults()" it seems this isn't working anymore, the catalog would return all brains instead of seraching the relevant ones... (completely ignoreing everything in REQUEST) instead i have to write now: tal:define="results python:here.Catalog.searchResults(REQUEST=request)" i suspect that the catalog was able to acquire REQUEST via self.REQUEST and this isn't working anymore. has anyone had a similar problem? i don't know what i have changed leading to these kinds of problems... best regards, juergen herrmann _______________________________________________________________________ >> XLhost.de - eXperts in Linux hosting << Jürgen Herrmann Bruderwöhrdstraße 15b, DE-93051 Regensburg Fon: +49 (0)700 XLHOSTDE [0700 95467833] Fax: +49 (0)721 151 463027 WEB: http://www.XLhost.de

POSKeyError nightmare
by Kevin Carlson 16 Oct '05

16 Oct '05

Hi all, Rather large message with tracebacks and all -- any help is greatly appreciated... I have tried to rid a large Zope DB of a POSKeyError to no avail. I have tried the method that traverses the folder which contains the offending object using try/except to catch the POSKeyError, but even those continually throw the error. Below is the traceback: ------------- Traceback (most recent call last): File "<stdin>", line 1, in ? File "error_finder.py", line 6, in error_finder for id, next_item in folder.objectItems(): File "/home/zope/instances/primary/Products/BTreeFolder2/BTreeFolder2.py", line 369, in objectItems self.objectIds(spec)) File "/opt/Zope-2.7/lib/python/Products/ZCatalog/Lazy.py", line 138, in __init__ else: self._len = len(seq) File "/opt/Zope-2.7/lib/python/ZODB/Connection.py", line 559, in setstate p, serial = self._storage.load(oid, self._version) File "/opt/Zope-2.7/lib/python/ZODB/FileStorage.py", line 689, in load return self._load(oid, version, self._index, self._file) File "/opt/Zope-2.7/lib/python/ZODB/FileStorage.py", line 657, in _load raise POSKeyError(oid) ZODB.POSException.POSKeyError: 00000000000e5fec -------------------- I also ran fsrefs.py and the output is below: -------------------- oid 0x47152L BTrees.OOBTree.OOBucket last updated: 2005-04-19 22:45:48.466296, tid=0x35CB635CECA1E99L refers to invalid object: oid 0xD5B62L missing: 'Products.CMFDefault.File.File' oid 0x25506L BTrees.OOBTree.OOBucket last updated: 2005-09-19 10:00:59.079910, tid=0x3601B18FC130433L refers to invalid objects: oid 0xE5FEBL missing: 'Products.CMFDefault.File.File' oid 0xE5FECL missing: 'BTrees.OOBTree.OOBucket' oid 0x393C8L BTrees.OOBTree.OOBucket last updated: 2005-06-28 08:05:37.236789, tid=0x35E42259EE080DDL refers to invalid object: oid 0xDB6C5L missing: 'Products.CMFDefault.File.File' oid 0x18235L BTrees.OOBTree.OOBucket last updated: 2005-09-03 05:26:28.090544, tid=0x35FC00677DA5D66L refers to invalid object: oid 0xD2F9BL missing: 'Products.CMFDefault.File.File' oid 0xE43BEL BTrees.OOBTree.OOBucket last updated: 2005-08-16 06:58:59.474963, tid=0x35F5B22FDC28500L refers to invalid objects: oid 0xE2A83L missing: 'Products.CMFDefault.File.File' oid 0xE2AADL missing: 'Products.CMFDefault.File.File' oid 0xE2AB8L missing: 'Products.CMFDefault.File.File' oid 0xE4FAEL BTrees.OOBTree.OOBucket last updated: 2005-08-29 04:59:25.040228, tid=0x35FA3CB6AD69B33L refers to invalid objects: oid 0xE19C4L missing: 'BTrees.IOBTree.IOBTree' oid 0xE19CDL missing: 'BTrees.IOBTree.IOBTree' oid 0xE19D7L missing: 'BTrees.IOBTree.IOBTree' ---------------- All of the objects that are causing the POSKeyError I believe to be coming from a single instance of a very large BTreeFolder2 instance. Can anyone offer any remedy to remove or repair the offending objects? Thanks, Kevin

Packaging a zope application
by Joshua Burvill 16 Oct '05

16 Oct '05

Hello All, I have a zope application which operates on data in an external relational database (Firebird), as well as containing lots of folders, dtml docs, scripts, zsql methods etc within the zope db I would like to get suggestions on the best way to package the whole application so that it is easy to set up from scratch. Currently there is a three step process: 1. install correct version of zope 2. unzip a zip file which I maintain that contains all the added libraries, products, .zexp file, and external methods into their correct paths in the zope root folder on the filesystem, then restart zope 3. Log into zope as admin and import the .zexp file into the zope root folder in the zope db Any suggestions of easier / better ways to do this would be much appreciated. Regards, Josh

Confusing DateTime().strftime behavior
by Kirk Strauser 16 Oct '05

16 Oct '05

I'm upgrading our server from a FoxPro backend to PostgreSQL, using the Psycopg connector. My problem is that the old database returned timestamps as a "%m/%d/%Y"-formatted string, while Psycopg returns a DateTime object (I'm using the internal module, not mxDateTime). Whenever I use strftime to format the object for display, I get the previous day's date instead. I've found several references to this problem in Google, but no one seems to have found a good solution. Any thoughts? -- Kirk Strauser The Day Companies
