Linux Startup problem
by Eddie Moench 01 Oct '03

01 Oct '03

Hi, I have to install ZOPE on a Linux machine (SuSE SLES-7). After installation I get this error message: ------ 2003-09-30T20:09:57 INFO(0) zdaemon Started subprocess: pid 17103 ------ 2003-09-30T20:09:58 PANIC(300) z2 Startup exception Traceback (innermost last): File /opt/csckm/zope/Zope-2.6.2-linux2-x86/z2.py, line 585, in ?

There must be another process that has opened the file. But there is definitely no process that has access to a ZOPE file! Has anyone a solution? Please. I'm not a Linux geek - do I have to set some special rights or something to the /var directory??? Just a guess... Pleas help, Thanks a lot, Best, Eddie. Eddie Moench.

Error logging
by Andreas Tille 01 Oct '03

01 Oct '03

Hi, today I had to deal with an access error and wanted to write a little cron job which informs me via mail that something was wrong at my Zope site. I do so for apache and did not expect any problem her but this seemed naive ... The only documentation I was able to find about writing error logs in Zope was http://www.zope.org/Documentation/Misc/LOGGING.txt but there is no date or version info in this text and because it is refering to a Python 1.5.2 version I doubt that this information might be outdated. Anyway - I do not understand this: Creating your own Zope logger is easy. Simply define a logger class with the following interface: ... I really can't imagine that I'm the only one who wants /var/log/zope/error.log without any intervention and so I hope there is a way which is "even more easy" than described above. ;-) Kind regards Andreas.

How to access the namespace of a Python Script?
by Elena Schulz 01 Oct '03

01 Oct '03

Hi, I try to do the following inside a python script: myDict={'myKey':'myVal'} myString='myDict' myObject = getattr(thisScriptNameSpace, myString) What should I write for 'thisScriptNameSpace' to get 'myObject' pointing to 'myDict'? In a 'normal' Python-Modul 'thisScriptNameSpace' should be 'self'. It should be possible in a Python Script, ins't it? -- Any hints are welcome, Elena

FTP server hangs on ls, put, get, ...
by Ian Beatty 01 Oct '03

01 Oct '03

Greetings. I've got a Zope installation that doesn't seem to want to do FTP. I can open a FTP connection to the server -- the authentication dialog goes okay -- and I can cd and pwd, but if I try to transfer any data (ls, put, get, etc.), the server seems to hang and eventually time out, terminating the connection. I can successfully FTP to other Zope servers. I've restarted Zope. I've tried connecting from several different client machines, and from different FTP client programs, and I get the same behavior each time. So, it seems to be something about that particular server (Zope 2.6.1 on Red Hat Linux 8). Anybody got any insightful advice or suggestions?

Help: My beloved Zope crashes
by Hanno Schlichting 01 Oct '03

01 Oct '03

Hi all. I've a serious problem and don't know where to look further for the error. Hope anyone can help. (Sorry for the crosspost.) My configuration: Hardware: 2x 750MHz, 1GB RAM Software: Windows 2000 SP4, Zope 2.6.2, CMF 1.3.2, Plone 1.0.5 and a variety of other products such as CMFForum, CMFCollector, CMFVisualEditor, Epoz, Photo and Photoalbum, TextindexNG, LocalFileSystem. Two weeks ago I upgraded to CMF 1.4.1 and a CVS Version of Plone 1.1 but undid (by overwritting with a backup copy of the whole zope directory) the changes because of some errors with the plone version. This might be unrelated but for one week knowing of no special changes my zope instance hangs everytime I change a document or try to add one. In detail: In the ZMI I try to change the content of a document. I click change and my browser gets no response. I can watch my zope instance collecting all free memory (~800MB) then suddenly releasing everything and then going into a cycle grabbing up to 40 MB going down to 0 and restarting this, the whole time with a processor load of 100 percent. It looks like some kind of infinite loop, but I have no idea what could cause this. I ran debug mode from the console but it tells me nothing. I ran fsrecover and fspack on the database file (about 400MB) but everything is fine. I assume something involved in the process of saving like the catalog or workflow might be the cause but I don't know how to track this down. Help of any kind is appreciated.

Invalid Characters for a URL?
by Edward Pollard 01 Oct '03

01 Oct '03

I'm porting some data to a Zope environment, and it is critical that URL's remain the same. However, Zope does not allow plus signs (+) in URL's. It tries to pass it off that plus is an invalid character for a URL. However, plus is a perfectly valid character for a URL (ref: http://www.ietf.org/rfc/rfc1738.txt) So, why is Zope doing this, and much more importantly what does Zope think ARE valid characters for a URL? --- Edward J.

Re: [Zope] FTP server hangs on ls, put, get, ...

On Tue, 30 Sep 2003 15:02:39 -0400, Paul Winkler <pw_lists(a)slinkp.com> is reputed to have said: > Is the server behind a firewall? > I've never been able to get ftp working through a firewall. Yes, it is. I've got Zope's FTP running on 8021 and that port in the firewall is open. Hmmm... I just tried turning off the firewall entirely, and FTP works. So maybe it's a firewall issue and not a Zope issue after all. My commercial service provider for a different Zope site I manage (Zettai.net) has FTP working, and they're very security conscious, so they must have figured out how to make it work. If anyone listening can tell me what firewall rules I'll need, I'd be grateful. Since it's no longer a Zope-specific issue, maybe you should just email me off-list.

RE: [Zope] Cataloging/ignoring objects that generate errors on in dexing
by Jean-Francois.Doyon＠CCRS.NRCan.gc.ca 01 Oct '03

01 Oct '03

OK, I've found the code that is causing this to happen: Zope 2.6.1, in Products/PluginIndexes/TextIndex/TextIndex.py, Line 291: except (AttributeError, TypeError): For some reason, the index_object method catches specific exceptions, not ALL exceptions. If I change this to a simple "except:", then my problem goes away. Conceptually, I would think this is better ... Just ignore ANY error that might occur and don't index the object ... Why only handle specific exceptions ? Is this a bug ?

TranslationService and charsets...

Hi zopistas... I can translate a message with... translated = context.translation_service.translate('mydomain', message) But how can I get the charset of the translated message, as the various languages from the associated MessageCatalog may have different charsets (ASCII, ISOxxx,...). Many thanks in advance for any hint. --Gilles
