Random Crashes/Freezes on FreeBSD 5.4-RELEASE
by alex＠schnarff.com 20 Feb '07

20 Feb '07

Hello All, I've recently inherited the job of co-administering an existing Zope 2.9 system that is performing very flakily. While I admit to knowing nothing about Zope administration before the last couple of weeks, I've been busy reading the mailing list archives, etc., and I'm convinced that something obscure is wrong in this particular installation. I'm hoping some kind/brave soul here can help me figure it out. Here's the setup, described in as much detail as I can (I'll be happy to provide additional tidbits as requested): * FreeBSD 5.4-RELEASE system w/generic kernel. Yes, I know this is old, I'm working on getting it upgraded. * Loads of good hardware: 3.2GHz P-4 processor w/hyperthreading enabled; 2GB memory; 240GB Seagate SCSI-3 disk. * Python 2.4.3 * Zope 2.9 * Apache 2.0.58, compiled with: -D APACHE_MPM_DIR="server/mpm/prefork" -D APR_HAS_SENDFILE -D APR_HAS_MMAP -D APR_HAVE_IPV6 (IPv4-mapped addresses enabled) -D APR_USE_FLOCK_SERIALIZE -D SINGLE_LISTEN_UNSERIALIZED_ACCEPT -D APR_HAS_OTHER_CHILD -D AP_HAVE_RELIABLE_PIPED_LOGS -D HTTPD_ROOT="/usr/local" -D SUEXEC_BIN="/usr/local/bin/suexec" -D DEFAULT_PIDLOG="/var/run/httpd.pid" -D DEFAULT_SCOREBOARD="/var/run/apache_runtime_status" -D DEFAULT_LOCKFILE="/var/run/accept.lock" -D DEFAULT_ERRORLOG="/var/log/httpd-error.log" -D AP_TYPES_CONFIG_FILE="etc/apache2/mime.types" -D SERVER_CONFIG_FILE="etc/apache2/httpd.conf" Compiled-In Modules: core.c prefork.c http_core.c mod_so.c Dynamically Loaded Modules (don't even get me started on the size of this list): LoadModule access_module libexec/apache2/mod_access.so LoadModule auth_module libexec/apache2/mod_auth.so LoadModule auth_anon_module libexec/apache2/mod_auth_anon.so LoadModule auth_dbm_module libexec/apache2/mod_auth_dbm.so LoadModule charset_lite_module libexec/apache2/mod_charset_lite.so LoadModule include_module libexec/apache2/mod_include.so LoadModule deflate_module libexec/apache2/mod_deflate.so LoadModule log_config_module libexec/apache2/mod_log_config.so LoadModule logio_module libexec/apache2/mod_logio.so LoadModule env_module libexec/apache2/mod_env.so LoadModule mime_magic_module libexec/apache2/mod_mime_magic.so LoadModule cern_meta_module libexec/apache2/mod_cern_meta.so LoadModule expires_module libexec/apache2/mod_expires.so LoadModule headers_module libexec/apache2/mod_headers.so LoadModule usertrack_module libexec/apache2/mod_usertrack.so LoadModule unique_id_module libexec/apache2/mod_unique_id.so LoadModule setenvif_module libexec/apache2/mod_setenvif.so LoadModule proxy_module libexec/apache2/mod_proxy.so LoadModule proxy_http_module libexec/apache2/mod_proxy_http.so <IfDefine SSL> LoadModule ssl_module libexec/apache2/mod_ssl.so </IfDefine> LoadModule mime_module libexec/apache2/mod_mime.so LoadModule dav_module libexec/apache2/mod_dav.so LoadModule status_module libexec/apache2/mod_status.so LoadModule autoindex_module libexec/apache2/mod_autoindex.so LoadModule asis_module libexec/apache2/mod_asis.so LoadModule info_module libexec/apache2/mod_info.so LoadModule cgi_module libexec/apache2/mod_cgi.so LoadModule dav_fs_module libexec/apache2/mod_dav_fs.so LoadModule vhost_alias_module libexec/apache2/mod_vhost_alias.so LoadModule negotiation_module libexec/apache2/mod_negotiation.so LoadModule dir_module libexec/apache2/mod_dir.so LoadModule imap_module libexec/apache2/mod_imap.so LoadModule actions_module libexec/apache2/mod_actions.so LoadModule speling_module libexec/apache2/mod_speling.so LoadModule userdir_module libexec/apache2/mod_userdir.so LoadModule alias_module libexec/apache2/mod_alias.so LoadModule rewrite_module libexec/apache2/mod_rewrite.so I will happily send along the full httpd.conf or zope.conf if requested. That all in mind, the behavior is difficult to accurately describe. On what appears to be a semi-random basis, things being served up by Zope are inaccessible from the web; clients get timeout messages from their web browser. While this is going on, things being served up directly by Apache are fine. Just to make things more confusing, when Zope flatlined this morning, I got the following message: Proxy Error The proxy server received an invalid response from an upstream server. The proxy server could not handle the request GET /portal. Reason: Error reading from remote server ...which is the first I've seen of any actual error messages when this behavior is occuring. For some reason that I'm unaware of, Zope will typically be restarted when this flatlining occurs; I think it's a process monitor tool one of my co-admins have installed, but I'm not 100% certain of that. Once it's restarted, things work fine. Does anyone have a clue what could be going on? Again, I'll be more than happy to supply additional info, run tests, whatever may be necessary to help figure out what the deal may be. Thanks, Alex Kirk

Cache values may only be in one cache
by Jonas Nielsen 19 Feb '07

19 Feb '07

I'm getting the following error: "Cache values may only be in one cache" I'm getting this error every time I refresh my skin product. So I have to remember to restart zope every time I make a change. I'm running Plone 2.5.2 and Zope 2.9.6 On this page: http://plone.org/documentation/error/one_cache Wichert Akkerman says: """Zope no longer supports product refreshing fully. For products using the component architecture it will probably never work. For others it can break as well. This is a Zope matter, not a Plone problem.""" Is this really true? Wouldn't it be an idea to remove the functionality completely then?

Re: problem with input elements and unicode/utf-8
by Jostein Leira 19 Feb '07

19 Feb '07

I have experienced on my installation that Zope decides that the character set should be iso-8859-1 for IE7 even no HTTP_ACCEPT_CHARSET is sent from IE7 and preferred charset is utf-8. Firefox submits HTTP_ACCEPT_CHARSET and Zope handles that OK. http://www.zope.org/Collectors/Zope/2280 <http://www.zope.org/Collectors/Zope/2280> I'm wondering what the correct way to set up Zope to use utf-8? Have set sys.setdefaultencoding('utf-8') in /usr/local/lib/python2.4/site.py. Have set management_page_charset='utf-8' as property of / in ZMI. Have set default-zpublisher-encoding utf-8 in etc/zope.conf. After the comments in the Collector above I'm wondering what to do if I should not set the sys.setdefaultencoding()? Not changing the default encoding I always get a decode error when trying to save a page template with non-ascii characters. Regards Jost

Hi all. I'm looking for an alternative to python gdchart for barchart/piechart in a web application. I'm looking to python gdchart 2, but I'm not sure on the status of maintenance of the project itself. Can someone provide advice? Regards Marco -- Marco Bizzarri http://iliveinpisa.blogspot.com/

Configure.zcml In Hello World Video On WorldCookery.Com Doesn't Work
by Mark, Jonathan (Integic) 16 Feb '07

16 Feb '07

Here is my configure.zcml file, which is identical to the one Paul Everitt says to write: <configure xmlns="http://namespaces.zope.org/browser"> <page name="hello" template="helloworld.html" for="zope.app.container.interfaces.Icontainer" permission="zope.Public" /> </configure> and here is the error message that I get when I reboot the Zope 3.3 server on Windows XP: ConfigurationError: ('Invalid value for', 'for', 'ImportError: Module zope.app.container.interfaces has no global Icontainer') Everything I did was identical to the training video. What went wrong?

cpu load 99 percent a lot in plone evinironment
by Marko Kruijer 16 Feb '07

16 Feb '07

We are running a seperate zope instance that contains a number of plone portal. Zope version 2.8.2 plone version 2.1.1 python 2.3.5 since a few weeks the instance 'hangs', When i check the processes usually python is at 99%, but i've also had time where zope was not responding but the server load was almost zero (deadlocking ?). I've installed deadlockdebugger and there are some entries of 'slow' pages in there, but i've checked these pages and they do not contain any 'big' queries or possible slow processes. The page loops over a results set from mysql, this set contains 400 - 500 results. I've noticed that if it loops over 500 results instead of i.e. 20 the page takes almost 3 to 4 seconds longer to load. I've never seen this kind of behaviour before (i have seen it with bad queries and such, but thats not the case here). Will a zope update possibly solve this problem, or can someone inform me about the deadlockdebugger output and HOW is should read it?

Extract Files from ZODB
by Carlosfocker 15 Feb '07

15 Feb '07

I have a ZODB that was being used by Plone to store files(Word documents, Images, etc.). Plone is no longer working. I want to extract (retrieve) the files from the ZODB. Is this possible? If so, how is this accomplished. Note: I cannot access Plone or anything in Plone because it is not working. I am looking for a solution that involves working only with ZODB through Zope, not a procedure that attempts to troubleshoot Plone.
