Re: [Zope] convert python to dtml

Why do you want to recode into DTML? I think that is piece of good code and much faster than DTML. You could try following replacing (original line of your code, follows with DTML code), but not tested: > rec = context.test_select_sql() <dtml-call "REQUEST.set(rec , test_select_sql())"> > print "Fields definitions" Fields definitions > recordset = rec.dictionaries() <dtml-let "recordset = rec.dictionaries()" > rownum = 1 <dtml-call "REQUEST.set(rownum,1)" > for record in recordset: <dtml-in recordset> > print "Row %d" % (rownum), "check", record Row <dtml-var rownum>, check <drml-var sequence-item><br> > rownum = rownum + 1 <dtml-call "REQUEST.set(rownum,rownum+1)" </dtml-in> and so on on the rest of code. > for key in record.keys(): > print key, "=", record[key] > print "-" * 80 > return printed

read-only-database
by Ulla Theiss 17 Mar '09

Hello list, I want to run the database in read-only mode from CD and configured it accordingly in the zope.conf: read-only-database on enable-product-installation off zserver-read-only-mode on Starting Zope, I get the following error: Traceback (most recent call last): File "\Programme\Zope\lib\python\Zope2\Startup\run.py", line 56, in ? run() File "\Programme\Zope\lib\python\Zope2\Startup\run.py", line 21, in run starter.prepare() File "E:\Programme\Zope\lib\python\Zope2\Startup\__init__.py", line 98, in pre pare self.startZope() File "E:\Programme\Zope\lib\python\Zope2\Startup\__init__.py", line 257, in st artZope Zope2.startup() File "E:\Programme\Zope\lib\python\Zope2\Startup\__init__.py", line 47, in sta rtup starter.setConfiguration(cfg) File "D:\Programme\Zope\lib\python\Zope2\App\startup.py", line 56, in startup File "D:\Programme\Zope\lib\python\DBTab\DBTab.py", line 96, in getDatabase File "D:\Programme\Zope\lib\python\DBTab\DBTab.py", line 113, in _createDataba se File "E:\Programme\Zope\lib\python\Zope2\Startup\datatypes.py", line 163, in o pen DB = self.createDB() File "E:\Programme\Zope\lib\python\Zope2\Startup\datatypes.py", line 160, in c reateDB return ZODBDatabase.open(self) File "D:\Programme\Zope\lib\python\ZODB\config.py", line 97, in open File "D:\Programme\Zope\lib\python\ZODB\config.py", line 133, in open File "D:\Programme\Zope\lib\python\ZODB\FileStorage\FileStorage.py", line 112, in __init__ File "D:\Programme\Zope\lib\python\ZODB\lock_file.py", line 57, in __init__ IOError: [Errno 13] Permission denied: '\\Zope-Instance/var/Data.fs.lock' r+ means opening the file for updating. This has not to do anything with read-only. Does anybody know what I have to configure additionaly, that read-only works? I run Zope 2.8.4 on windows. Many thanks in advance, Ulla.

Yup, that and Squid 3's "not production quality" status makes the whole Squid/ESI thing a total non-starter, which is a shame... ...but I do wish, as a result, that people would stop touting it as a way to scale Zope apps. cheers, Chris -- Simplistix - Content Management, Zope & Python Consulting - http://www.simplistix.co.uk

acl_users
by Sean Duffy 21 Jun '07

21 Jun '07

Hi, I'm trying to do a batch add of users to the standard acl_users folder. Note quite a total success or total failure just yet. First I made a text file (usr_pwd.txt) in the form of password space username. and placed it (temporarily) in the Extensions directory. Then an external method (LoadUsers) to read it: def LoadUsers(self): f=open('/var/lib/zope/Extensions/usr_pwd.txt', 'r') y=f.readlines() return y And a script (user_load): ## Script (Python) "user_load" ##bind container=container ##bind context=context ##bind namespace=_ ##bind script=script ##bind subpath=traverse_subpath ##parameters= ##title= ## y=context.LoadUsers() for x in y: z=x.split(' ') acl = container.restrictedTraverse( '/foobar/acl_users' ) acl.userFolderAddUser( z[1], z[0], '', '' ) return 0 I hit the Test tab and now I have an acl_users folder full of users with the correct user names, and their passwords show the correct number of characters, however I can't log in using any of the user/password combinations. Should the path '/foobar/acl_users' been simply '/foobar/' or '/foobar' ? Any suggestions? Thanks, Sean

Zope hangs and Python eats all memory
by Nico Grubert 06 Mar '07

06 Mar '07

Dear list members, I am running Zope 2.9.6. on a 64-Bit Suse Linux 10.1 machine (9 Gbyte of RAM) with Python 2.4.3. installed. From time to time, Zope hangs and I cannot access it anymore. I tried to use the "Zope DeadlockDebugger" but if my Zope hangs I cannot call the URL "http://myzopesite:8080/manage_debug_threads?secret_password" to let Zope DeadlockDebugger show any useful information. Zope does not response. If Zope hangs, the python process eats all the memory and the machine starts to swap. The "top" command in the shell tells me: ------------------------------------------------------------------------- Tasks: 91 total, 2 running, 89 sleeping, 0 stopped, 0 zombie Cpu(s): 10.4%us, 0.4%sy, 0.0%ni, 89.0%id, 0.2%wa, 0.0%hi, 0.0%si Mem: 9041256k total, 9025124k used, 16132k free, 10604k buffers Swap: 4208988k total, 4208988k used, 0k free, 9472k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 29992 wwwrun 16 0 12.0g 8.3g 2860 S 19 95.9 3:52.66 python ------------------------------------------------------------------------- There are several add-ons for Zope installed, like: - "Psycopg" Postgres Database Adapter - "mxODBCDA" ODBC Database Adapter - LDAPUserfolder - "Silva" Content Management System - PIL Furthermore, I see a lot of Conflict Errors in the "event.log" like e.g.: ------------------------------------------------------------------------- ZPublisher.Conflict ConflictError at /VirtualHostBase/http/193.134.202.20:80/mysite/VirtualHostRoot/: database conflict error (oid 0x0435, class BTrees._OOBTree.OOBTree, serial this txn started with 0x036aeb14ab1c4b88 2007-01-15 12:04:40.104030, serial currently committed 0x036aeb1d0cc5d099 2007-01-15 12:13:02.993605) (80 conflicts (0 unresolved) since startup at Mon Jan 15 11:44:55 2007) ------------------------------------------------------------------------- These kind of Conflict errors occur almost every minute. It might be that these errors have something to do with it but I am not sure. How can I figure out what exactly causes Zope to hang? If you need more information, please let me know. Thanks in advance... Regards, Nico

Wrong time displayed on events
by Kirk Strauser 09 Feb '07

09 Feb '07

I've just installed Plone 2.5.1 on Zope 2.9.6 running on FreeBSD 6-STABLE. On my newly created Plone site, whenever I add an event, it's displayed with the wrong time. For instanced, if I create one that runs between 2006-12-05 19:30 and 22:00, it gets rendered like: (<span class="location">Some Event</span>, from <abbr class="dtstart" title="2006-12-05 19:30:00">2006-12-05 13:30</abbr> to <abbr class="dtend" title="2006-12-05 22:00:00">2006-12-05 16:00</abbr>) The server and I live in the CST time zone, which accounts for the 6-hour offset (as though I entered the time in UTC and it's converting it to CST for display). But since I never entered a timezone anywhere, why's it doing any conversion at all instead of just assuming that all times entered are local to the server? Is there a way to fix this, other than deliberately entering all times for events six hours too late, and letting Plone "fix" the display? -- Kirk Strauser Daycos

Hi, in CookieCrumbler.modifyRequest I see: self.delRequestVar(req, self.auth_cookie) and was wondering why the auth cookie is deleted from the request every time? Thanks, Mark

Zope + Oracle + Cron
by David VanKirk 05 Feb '07

05 Feb '07

We have zope installation that uses an Oracle backend to store data on. We also have the system setup to do a backup of the database and Zope Installation everyday. Everything runs smoothly until it comes time to start Zope back up. For some reason whenever the script tries to start Zope back up, it comes up but with a broken ZOracleDA product. It complains about not being able to find the library file called libclntsh.so.9.0. If I try to start Zope myself from command line right after the script is done running (actually stop it then start it again) it works and connects to Oracle fine. I've tried using "nice" to up the priority level but it doesn't seem to work. I also thought that maybe I wasn't giving oracle enough time to start up so I've tried adding sleep commands to the script, again, with no luck. If anyone has any experience in this field or has any suggestions, please let me know. This is a quite annoying situation, as this server is quite important to the company and downtime is a bad thing. -David

single sign-on
by John Fugazi 05 Feb '07

05 Feb '07

I have installed Plone with openSUSE 10.2 (working). I have also installed LDAPUserFolder and LDAPMultiPlugins (working). The default installation of Plone is located in "/var/opt/zope/default". I have loaded mod_proxy, mod_proxy_http, mod_rewrite and mod_headers. I have also compiled and load mod_ntlml. I tested mod_ntlm on just an ordinary directory that contained an "index.html" and it worked fine. Mod_ntlm asked for username and password, which authenticated. I set internet explorer to "automatic logon with current username and password" and i was able to get to the web page without typing a username and password. This is my conf, but this does not work. <VirtualHost 192.168.200.20:80> ServerName openSUSE ServerSignature On RewriteEngine On <Location "/var/opt/zope/default"> AuthName "Active Directory Domain" AuthType NTLM NTLMAuth on NTLMAuthoritative on NTLMDomain domain NTLMServer ads require valid-user RequestHeader set REMOTE_USER %{REMOTE_USER}e </ Location> RewriteRule ^/(.*) \ http://localhost:8080/VirtualHostBase/http/%{HTTP_HOST}:80/VirtualHostRoot/… \ [L,P,E= REMOTE_USER:%{LA-U:REMOTE_USER}] </VirtualHost> Any suggestions???? _________________________________________________________________ >From predictions to trailers, check out the MSN Entertainment Guide to the Academy Awards® http://movies.msn.com/movies/oscars2007/?icid=ncoscartagline1
