Restart button corrupted data.fs.index file
by Kit O'Connell 11 Oct '00

11 Oct '00

After installing two new Products (ZCounter the first time,and FSCounter the next time), I hit the Restart button in the Zope Control Panel. Zope did not come up. I tried a manual stop/start. The start resulted in this error message: > Traceback (innermost last): > File "/usr/home/txpn/Zope/z2.py", line 554, in ? > exec "import "+MODULE in {} > File "<string>", line 1, in ? > File "/usr/home/txpn/Zope/lib/python/Zope/__init__.py", line 110, in ? > DB=ZODB.FileStorage.FileStorage(Globals.BobobaseName) > File "/usr/home/txpn/Zope/lib/python/ZODB/FileStorage.py", line 292, in +__init__ > r=self._restore_index() > File "/usr/home/txpn/Zope/lib/python/ZODB/FileStorage.py", line 427, in +_restore_index > info=p.load() > cPickle.UnpicklingError: pickle data was truncated The data.fs.index file was then corrupt. If I renamed it, and tried another start, Zope would start fine. I did this twice w/ the same results. I'm using Zope 2.2.2. Stevea on #zope suggested Jim might be interested in this, and that I should also send it to a Zope mailing list -- since I'm not on Zope Dev yet, I'm sending it here. I have a copy of the old index files if anyone needs to see them. Cheers, Kit

Namespace within a product... (argh...)
by Pierre-Julien Grizel 11 Oct '00

11 Oct '00

Well, beeing very straightforward, I read this, in OSFP/Help/DTMLDocument.py : """ A DTMLDocument implicitly pass itself as a client argument in addition to the specified client, so names are looked up in the DTMLDocument itself. Passing in a namespace to a DTML Document is often referred to as providing the Document with a *context*. DTML Documents are called three ways: From DTML -- A DTML Document can be called from another DTML Method or Document:: <dtml-var standard_html_header> <dtml-var aDTMLDocument> <dtml-var standard_html_footer> In this example, the Document 'aDTMLDocument' is being called from another DTML object by name. The calling method passes the value 'this' as the client argument and the current DTML names pace as the REQUEST argument. The above is identical to this following usage in a DTML Python expression:: <dtml-var standard_html_header> <dtml-var "aDTMLDocument(_.None, _)"> <dtml-var standard_html_footer> From Python -- Products, External Methods, and PythonMethods can call a DTML Document in the same way as calling a DTML Document from a Python expression in DTML; as shown in the previous example. By the Publisher -- When the URL of a DTML Document is fetched from Zope, the DTML Document is called by the publisher. The REQUEST object is passes as the second argument to the Document. """ So - I had a look at DTMLDocument.py and saw the following method : def __call__ (self, client = None, REQUEST = {}, **kw): ... SO - I try to create this method for my product : def __call__ (self, client = None, REQUEST = {}, **kw): print client print REQUEST and it prints : None {} It seems that in fact the DTML document doesn't actually pass _.None and _ to my object. WHY ?????? How can I enforce DTML Docs/Meths to pass it anyway ??? Many thanks, P.-J. -- If the only tool you have is a hammer, you tend to see every problem as a nail.

Bizarre ZMySQLDA problem...
by Tony McDonald 11 Oct '00

11 Oct '00

Hi all, I've just installed Zope-2.2.1 onto a clean Solaris 8 machine. I've built Python 1.5.2 from source and have MySQL 3.22 on the server. I've compiled up the ZMySQLDA product and put the MySQLModule.so in the correct place (ie one directory up from the src directory). I've restarted the Zope server, checked that ZMySQLDA is not broken and created a connection: test@localhost root I've created a ZSQL method that is essnetially 'select * from my_table' (and there *is* data in this table). The DA reports: There was no data matching this Z MySQL Database Connection (connected) query. The same query produces a flood of data from the mysql monitor. I'm totally baffled here, and would really appreciate any advice...

Have someone tried Zope with Stackless. Is that stable? I don't know to much about Stackless internals. Which modules are incompatible with Stackless? Anc D extensions?

acl_user and parent directory
by Stephan Goeldi 11 Oct '00

11 Oct '00

When I create a user in a subfolder, he can view the files in the parent folders: /www/folder1 /www/folder2 The manager of folder1 can not only view the content of /www but the content and the files of /www/folder2 too. This is BAD security IMHO. I don't want the user of folder1 let to know, that there exists a folder2! _________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.

Easiest way to turn X-Forwarded-For to Remote-IP?
by Marcin Kasperski 11 Oct '00

11 Oct '00

I use Zope via Apache proxy, what causes some trouble (all remote IPs for Zope are equal to 127.0.0.1). As I finally installed mod_proxy_add_forward, I get original address in X-Forwarded-For header (REQUEST['HTTP_X_FORWARDED_FOR']). The question is: can I do something easy to automatically perform if(remote_ip = 127.0.0.1 and X-Forwarded-For exists) then set remote_ip = whatever is in X-Forwarded-For logic? In particular, I would like changed IP to be used by Zope access control and Zope log.

Medusa Monitor
by Hung Jung Lu 11 Oct '00

11 Oct '00

Hi, Zope comes with the Medusa monitor (port 8099 by default) which is kind of cute and allows one to get into the guts of Zope. But do people really use it? How do people use it? Is there any document describing the usages of this monitor? Are there some features of this monitor that makes debugging easier? regards, Hung Jung _________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.
