filesystem directory view
by David Bear 25 Sep '05

25 Sep '05

I have cmf1.4.7 installed on zope 2.7.4. I also have plone installed. All seems to work well. I'm trying to use the file system directory view product to build a simple graphics library. My thinking was to store all images on the unix file system, then let some store some meta data on each image. Trouble is, I'm not finding any 'beginning' documentation on using file system directory view. seach zope.org <http://zope.org> yeilds hundreds of hits. I've looked through the install tree for zope and cmf and am not finding any usefull README's there either. so my first question is where is a good HOWTO on using filesystem directory view (I've got both the fdv that came with cmfcore and one that came with plone). my second question is, .. is file system directory view what I want. Again, I want to store files in the unix file system, expose those to zope, then store meta data on each of those image in zodb. -- David Bear What's the difference between private knowledge and public knowledge?

Apache/Zope port redirection basic questions...
by seberino＠spawar.navy.mil 25 Sep '05

25 Sep '05

I made Apache redirect certain URLs to a Zope/Plone site on port 8280 and it works. (e.g. mysite.com/lef --> mysite.com:8280/lefiss) Question #1: I'm not sure now what is the need for Plone/Zope's Virtual Host Monster??? Apache seems to take care of proxying/redirection BY ITSELEF!?!?!? Question #2: Zope/Plone site displays port 8280 in the client browser..... If Apache tries to *hide* the redirection....why does Zope/Plone reveal the true port and how tell ZOpe/Plone to hide this fact again? Thanks! Chris

SQL query in ZSQLMethod
by celtek＠wp.pl 25 Sep '05

25 Sep '05

Hi, In ZSQLMethod I would have SQL query similar to this logic: IF value1=<dtml-var value1> and value2=<dtml-var value2> THEN update table set( name='<dtml-var name>' )where value1=<dtml-var value1> and value2=<dtml-var value2> ELSE insert into table values( Id, name='<dtml-var name>', value1=<dtml-var value1>, value2=<dtml-var value2> ) I can't figure out how to change this notation. Many greetings and thanks for every answer!

POSKeyError nightmare
by Kevin Carlson 25 Sep '05

25 Sep '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

securing webdav
by David Bear 24 Sep '05

24 Sep '05

I run zope in back of apache, and let apache handle tls/ssl. In all the searching on zope.org <http://zope.org> though I haven't found any documents on how to let apache handle securing webdav for zope as well. Anyone see/written such? -- David Bear What's the difference between private knowledge and public knowledge?

ZSQL pluggable brains
by Chris Hoy 24 Sep '05

24 Sep '05

Hi I have been using ZSQLMethods object some with some without pluggable brains. I have come across a problem where the results of the sql query are not refreshed even thought the database is updated. I have noticed that the problem only occurs to those ZSQLMethods that have pluggable brains. It doesn't happen all the time. Has anybody come across a similar problem? Chris Hoy
