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

z3c.form 1.4.0, z3c.formui 1.1.0, and z3c.formdemo 1.2.0 released!
by Stephan Richter 04 Jul '07

04 Jul '07

Hello everyone, again thanks to the great feedback we received -- especially from David Pratt, Roy Mathew, and Joachim Werner -- we were able to fine-tune our new form framework even more to make it as robust of a foundation as possible for your projects! New features include group support, fully internationalized widgets for number and calendar fields, a richer select widget, refined form templates, and of course a new demo! BTW, congratulations to Roger who became father for the third time last weekend! Again for the curious and impatient ... --------------------------------------- There is also a new demo, of course! The "Questionnaire" demo provides a form for filling out a simple questionaire about someones Zope community involvement and then provides a very simple results page. Technically this demo (available for the DIV- and Table-based layouts) demonstrates the usage of groups, a new feature of this release, as well as writing attribute value adapters. To run the demos do the following:: $ svn co svn://svn.zope.org/repos/main/z3c.formdemo/trunk formdemo $ cd formdemo $ python bootstrap.py $ ./bin/buildout -N $ ./bin/demo fg Now you can access the demo under: http://localhost:8080/ On the Javascript Front ----------------------- Paul has made some great progress recently and we have now two demos working, including a fully Javascript-driven calculator. I'll leave it up to Paul to decide whether he wants to make an announcement, but he will be definitely promoting his work at EuroPython! <secret>To see the demos: Replace "formdemo" with "formjsdemo" and follow the instructions above.</secret> Changes ------- z3c.form ~~~~~~~~ - Feature: The select widget grew a new ``prompt`` flag, which allows you to explicitely request a selection prompt as the first option in the selection (even for required fields). When set, the prompt message is shown. Such a prompt as option is common in Web-UIs. - Feature: Allow "no value message" of select widgets to be dynamically changed using an attribute value adapter. - Feature: Internationalized data conversion for date, time, date/time, integer, float and decimal. Now the locale data is used to format and parse those data types to provide the bridge to text-based widgets. While those features require the latest zope.i18n package, backward compatibility is provided. - Feature: All forms now have an optional label that can be used by the UI. - Feature: Implemented groups within forms. Groups allow you to combine a set of fields/widgets into a logical unit. They were designed with ease of use in mind. - Feature: Button Actions -- in other words, the widget for the button field -- can now be specified either as the "actionFactory" on the button field or as an adapter. - Bug: Recorded all public select-widget attributes in the interface. z3c.formui ~~~~~~~~~~ - Feature: Registered all defined macros for each form template. Also, added more slots to the templates providing more hooks for customization. - Feature: Added a macro/slot for the "required info", which explains how required fields are marked. - Feature: Added support for form labels. - Feature: Added support for groups to templates. z3c.formdemo ~~~~~~~~~~~~ - Feature: Added new field "promptChoiceField" to the "All Widgets" demo demonstrating the prompt message of the select widget. - Feature: Increased the integer default value of "All Widgets" demo to show off our new internationalized converter. - Feature: Made ``bytesField`` and ``passwordField`` non-required, since they do not show their default values prohibiting the form to successfully submit, which can be annoying when playing around. - Feature: New "Questionnaire" demo shows how to use groups effectively. It also demonstrates how the label of buttons and widgets can be changed using attribute value adapters. Enjoy!

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.

Mac OS X Server StartupItem for Zope
by cristopher pierson ewing 28 Jun '07

28 Jun '07

Hello, I'm trying to get a startup item set up under OS X Server 10.4 on an Intel XServe box. I'd like not to have to manually restart Zope every time a software update forces me to restart the machine. I've gotten the following written up, but it failed to run for some unspecified reason. Here's the plist: { Description = "Zope Application Server"; Provides = ("Application Server"); Uses = ("Disks", "NFS"); } And the startup script: #!/bin/sh ## # Zope Application Server ## . /etc/rc.common ZOPE_APP_BASE=/path/to/zope/instances; export ZOPE_APP_BASE StartService () { ConsoleMessage "Starting Zope Application Server" ${ZOPE_APP_BASE}/mysite1/zopectl start ${ZOPE_APP_BASE}/mysite2/zopectl start } StopService () { ConsoleMessage "Stopping Zope Application Server" ${ZOPE_APP_BASE}/mysite1/zopectl stop ${ZOPE_APP_BASE}/mysite2/zopectl stop } RestartService () { ConsoleMessage "Stopping Zope Application Server" ${ZOPE_APP_BASE}/mysite1/zopectl restart ${ZOPE_APP_BASE}/mysite2/zopectl restart } I have multiple zope instances running, and need to start them all, and this is my attempt, but it doesn't work. Anyone out there have a successful StartupItem script that I could model mine after? Alternatively, anyone have any debugging experience on StartupItems and could point me at how to figure out more than 'it failed' (which is all the system log tells me)? thanks in advance for any advice you all might have!
