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

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

KeyErrors in Zope using ZEO
by Mike Patterson 03 Jul '07

03 Jul '07

Hi, We've been experiencing two KeyError problems with Zope since moving to a ZEO environment at the beginning of the year. On the server that the ZEO server resides we have 3 Zope instances running, and each of them gets a KeyError about once or twice a week individually. Restarting the offending instance takes care of the issue, but I was wondering if anyone has an idea of why we would be seeing these. Thanks, Mike The error that we get is: 2007-05-02T19:18:45 ERROR ZODB.Connection Couldn't load state for 0x1c2d6e Traceback (most recent call last): File "/opt/Plone-2.5/lib/python/ZODB/Connection.py", line 732, in setstate self._setstate(obj) File "/opt/Plone-2.5/lib/python/ZODB/Connection.py", line 768, in _setstate p, serial = self._storage.load(obj._p_oid, self._version) File "/opt/Plone-2.5/lib/python/ZEO/ClientStorage.py", line 746, in load return self.loadEx(oid, version)[:2] File "/opt/Plone-2.5/lib/python/ZEO/ClientStorage.py", line 774, in loadEx self._cache.store(oid, ver, tid, None, data) File "/opt/Plone-2.5/lib/python/ZEO/cache.py", line 293, in store self.fc.add(o) File "/opt/Plone-2.5/lib/python/ZEO/cache.py", line 980, in add available = self._makeroom(size) File "/opt/Plone-2.5/lib/python/ZEO/cache.py", line 915, in _makeroom size, e = self.filemap.pop(ofs) KeyError: 19826745 -------------------------------------------------------------- Each Zope instance has a configuration file containing this: <zodb_db main> # Main FileStorage database <zeoclient> server localhost:8100 storage 1 name zeostorage var $INSTANCE/var </zeoclient> pool-size 10 cache-size 10000 mount-point / </zodb_db> <zodb_db temporary> # Temporary storage database (for sessions) mount-point /temp_folder container-class Products.TemporaryFolder.TemporaryContainer pool-size 10 <zeoclient> server localhost:8100 storage temp name temp var $INSTANCE/var </zeoclient> </zodb_db> -------------------------------------------------------------- And the zeo.conf file looks like: %define INSTANCE /opt/Plone-2.5/zeocluster/server <zeo> address 8100 read-only false invalidation-queue-size 1000 # pid-filename $INSTANCE/var/ZEO.pid # monitor-address PORT # transaction-timeout SECONDS </zeo> <filestorage 1> path $INSTANCE/var/Data.fs </filestorage> %import tempstorage <temporarystorage temp> name temporary storage </temporarystorage> <eventlog> level info <logfile> path $INSTANCE/log/zeo.log </logfile> </eventlog> <runner> program $INSTANCE/bin/runzeo socket-name $INSTANCE/var/zeo.zdsock daemon true forever false backoff-limit 10 exit-codes 0, 2 directory $INSTANCE default-to-interactive true user plone python /opt/Plone-2.5/Python-2.4.3/bin/python zdrun /opt/Plone-2.5/lib/python/zdaemon/zdrun.py # This logfile should match the one in the zeo.conf file. # It is used by zdctl's logtail command, zdrun/zdctl doesn't write it. logfile $INSTANCE/log/zeo.log </runner> -------------------------------------------------------------- Also, on a different server that connects to the same ZEO server, occasionally upon startup we'll be greeted by the following error error.

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

a batch of inSaNitY!
by Programmer 07 Jun '07

07 Jun '07

Hi I am about to go stark, raving, frothing mad with the DTML-IN batching. Is there a known (or unknown) bug with this? I have searched and read everything I can find about this and no luck. The problem is with carrying the query terms over from one batch page to the next. Right now I am using the script found here: http://mail.zope.org/pipermail/zope-collector-monitor/2003-May/002001.ht ml Except I changed, <dtml-let batch="_.range(100, 180)" batch_size="10" batch_start="REQUEST.get('batch_start',1)"> To <dtml-let batch="myZSQLMethod1" batch_size="10" batch_start="REQUEST.get('batch_start',1)"> The mySQLMethod1 takes two params which the search form supplies to REQUEST. This works great. The pagination works beautifully. However, when I use the very same result script with myZSQLMethod2 (same DB table), which takes 5 params (all optional) the pagination breaks and no-longer passes the query terms. I have checked and rechecked both scripts and both forms. The ZSQLMethods both test good. I am out of ideas. For the life of me I cannot figure out why I'm losing my query terms in one and not the other when the two are almost identical. Care to enlighten me with your collective wisdom?

Five: Adapter registry not working?
by Peter Sabaini 04 Jun '07

04 Jun '07

Hi list, I am clearly doing something wrong here. I try to use an Adapter from zope.app.session with an HTTPRequest object, but the Adapterregistry doesnt quite cooperate. Specifically, I try to adapt a HTTPRequest object to zope.app.session.interfaces.IClientId via the Adapter zope.app.session.session.ClientId A short demo: % ./zopectl debug [ ... ] Import stuff: >>> from ZPublisher.HTTPRequest import * >>> from StringIO import StringIO >>> from zope.app.session.session import ClientId >>> from zope.app.session.interfaces import IClientId >>> from zope import component >>> from zope.interface import * Create ourselves a faux request object: >>> env = {'SERVER_NAME': '', 'SERVER_PORT' : ''} >>> request = HTTPRequest(StringIO(), env, None) ClientId implements IClientId: >>> list(implementedBy(ClientId)) [<InterfaceClass zope.app.session.interfaces.IClientId>] It seems ClientId is an Adapter for IRequest: >>> component.adaptedBy(ClientId) (<InterfaceClass zope.publisher.interfaces.IRequest>,) request implements IBrowserRequest, which is a subclass of IRequest: >>> list(providedBy(request)) [<InterfaceClass zope.publisher.interfaces.browser.IBrowserRequest>] >>> issubclass(list(providedBy(request))[0], component.adaptedBy(ClientId) [0]) True ...so I'd expect to get ClientId as an Adapter for IClientId(request), but I dont: >>> IClientId(request) Traceback (most recent call last): File "<stdin>", line 1, in ? TypeError: ('Could not adapt', <HTTPRequest, URL=http://:>, <InterfaceClass zope.app.session.interfaces.IClientId>) Shouldnt this work? Obviously I am missing something here. This is on Zope 2.10.2 with the built-in Five, and Python 2.4.4 Any help greatly appreciated! - peter.

MemoryError exception when importing a zexp file
by Ben Lobo 04 Jun '07

04 Jun '07

Hi, I'm trying to import a .zexp file that's 1.6GB but it continually fails due to a MemoryError exception. I guess that adding more RAM would probably fix this problem but does anyone know if there's any way of getting around this sort of problem without increasing the RAM? This is the traceback: -- Site Error An error was encountered while publishing this resource. exceptions.MemoryError Sorry, a site error occurred. Traceback (innermost last): a..
