Corrupted Data.fs alert when compacting
by Gilles Lenfant 23 Feb '04

23 Feb '04

Hi, My Zope instance (2.6.2) doesn't alert or log anything about ZODB corruption at startup or when browsing, but when I try to compact it, I got this error: Error Type: CorruptedError Error Value: C:\Program Files\Zopista_2_6_1\var\Data.fs:9676045:time-stamp reduction: 0342993b626b50b3 <= 034abe992d2f1aa2 The full traceback is... Traceback (innermost last): Module ZPublisher.Publish, line 98, in publish Module ZPublisher.mapply, line 88, in mapply Module ZPublisher.Publish, line 39, in call_object Module App.ApplicationManager, line 353, in manage_pack Module ZODB.DB, line 526, in pack Module ZODB.FileStorage, line 1503, in pack Module ZODB.fspack, line 680, in pack Module ZODB.fspack, line 464, in findReachable Module ZODB.fspack, line 478, in buildPackIndex Module ZODB.fspack, line 175, in checkTxn Module ZODB.fspack, line 170, in fail CorruptedError: C:\Program Files\Zopista_2_6_1\var\Data.fs:9676045:time-stamp reduction: 0342993b626b50b3 <= 034abe992d2f I have tried to run .../lib/ZODB/fsrecover.py utility, but the result is worse than the previous problem: How can I "uncorrupt" that ZODB and compact it again ? Is there another solution than exporting root folderishes and importing them in a clean new instance ?

Cann't access zope
by Hong Yuan 23 Feb '04

23 Feb '04

I am running the latest Debian 3.0 testing distribution and just installed zope 2.6.2-6. I tried to start zope with: debian:/etc/init.d# ./zope start Starting Zope instance default... Waiting instances in late: default(0), done. However, I can not access zope at the default port at 8080. It seems no application is listing on that port, according to the netstat -l result. The ps command show that zope seems to run well: zope 11704 11685 0 01:56 ? 00:00:05 /usr/bin/python2.2 /usr/lib/zope/z2.py --icp 9676 -W 9674 -m 9675 -l /var/log/zope/default/Z2.log --pid /var/run/zope/default/Z2.pid -f 8021 -p /var/lib/zope/cgi-bin/default -u zope -M /var/log/zope/default/Z2-detailed.log -z /usr/lib/zope -w 9673 INSTANCE_HOME=/var/lib/zope/instance/default SOFTWARE_HOME=/usr/lib/zope/lib/python Can anybody give me an idea what could be missed? Any tip would be appreciated.

FTP and firewall
by Robert Jean 23 Feb '04

23 Feb '04

Hello, For users on the internal network, the Zope 2.6 FTP server works fine. However, we wish to expand the application to distributed clients over the internet. The hardware used is a CISCO PIX 501 firewall. The current settings are as follows: access-list outside-in permit tcp any host <WAN IP ADDRESS> eq 8021 static (inside,outside) <WAN IP ADDRESS> xxx.xxx.x.xxx netmask 255.255.255.255 0 0 The problem is, I suspect as per the FTP protocol, the client decides the local socket of the data channel (not very good for firewall support). However, I have been successful with other standard FTP servers using similar treatment. Is there a resolution to this issue? Thank you, Robert __________________________________ Do you Yahoo!?

It seems that you stored the result of a Z SQL Method as an attribute of a persistent object. This is impossible as such instances cannot be unpickled (aka unserialized). It might not be easy to fix this problem. If you are lucky, the fatal modification is still listed in your "Undo" tab. In this case, undo the respective transaction. If not, a bit of surgery will be necessary to get rid of the attribute again. There is a HowTo around (I think on ZopeLabs) that explains how to get rid of an object causing a "POSKeyError". A similar approach can be used to get rid of your problematic attribute. BEWARE: do not store Z SQL Method results as part of any persistent object (this also implies: do not store it in a session). By the way: the code fragment you posted seems innocent (with respect to your current problem). The true problem must be elsewhere. >> >class testclass(SimpleItem, Folder): >> >... >> > def getTable(self,REQUEST=None): >> > "get table with results" >> > self.parm1=0 >> > self.REQUEST.set('sql',self.sql()) >> > >> > if REQUEST is not None: return >> >> > >> > self.showResult_html(self, REQUEST) -- Dieter

Identifying object type
by John Poltorak 23 Feb '04

23 Feb '04

I have just uploaded a Link object to Plone using FTP but Plone sees it as a Document type rther than a Link type. How do I change the type? Doesn't Zope use the 'Type' keyword in the file to identify the object type? -- John

SSL: key and certificate
by Yannick Turgeon 23 Feb '04

23 Feb '04

Hello all, I just installed Zope and then ZServerSSL. Then I created a client and everything is going fine using https protocol... and the "temporary" key and certificate provided with ZServerSSL. I tryed to generate new ones in two similar but differents ways. In both case, when I execute runzope, it's asking me for my passphrase. It's working when I enter it but it's anoying. I'm really not sure I'm asking this question to the good group since it looks more SSL related. But maybe someone of you have faced this same problem. Thanks for your time.

Zope FTP
by John Poltorak 23 Feb '04

23 Feb '04

If someone is familiar with Zope's FTP can you show what a directory listing looks like when you have logged in? I've tried using list and nlst, two of the available commands according to help, but neither shows anything. Normal FTP commands (ls, cd) do not work at all. -- John
