Hi all: Can I add something to a url based on it. Meaning I want to place some extra code to the link if it is to another site other than my own.

urgent stability problem on production site
by Frank Tegtmeyer 31 Jan '02

31 Jan '02

Hi, the ZPatterns list seems to be misconfigured - I cannot reach the list or someone at eby-sarna.com. So I post my problem here: Today we got online with a customer site and unfortunately instantly got a problem with ZPatterns or TransactionAgents, I don't really know. The site is quite heavily used - 40000 users that got a registration this night try to change their username and password now. All works very well and fast. The problem is that the Zope process dies once in a while - a while varies from 20 seconds to 20 minutes. I saw a relationship between login tries (login form) and the Zope process dying. Unfortunately this happens randomly - always when Zope dies shortly before that somebody tried a login. At the other side many logins work without Zope dying. The error log shows: 2002-01-30 11:02:25.627043500 2002-01-30T10:02:25 INFO(0) Z2 CONFLICT Competing writes at, /galileo/ssl/l ogin/ 2002-01-30 11:02:25.627844500 Traceback (innermost last): 2002-01-30 11:02:25.627849500 File /web/Zope-2.4.3/lib/python/ZPublisher/Publish.py, line 175, in publi sh 2002-01-30 11:02:25.627852500 File /web/Zope-2.4.3/lib/python/Zope/__init__.py, line 240, in commit 2002-01-30 11:02:25.627855500 File /web/Zope-2.4.3/lib/python/Products/TransactionAgents/__init__.py, l ine 54, in new_commit 2002-01-30 11:02:25.627858500 File /web/Zope-2.4.3/lib/python/ZODB/Transaction.py, line 302, in commit 2002-01-30 11:02:25.627861500 File /web/Zope-2.4.3/lib/python/ZODB/Connection.py, line 324, in commit 2002-01-30 11:02:25.627889500 ConflictError: '\x00\x00\x00\x00\x00\x00\x00\x02' 2002-01-30 11:02:25.627891500 2002-01-30 11:02:25.627892500 2002-01-30 11:02:26.203482500 ------ 2002-01-30 11:02:26.203488500 2002-01-30T10:02:26 INFO(0) Z2 CONFLICT Competing writes at, /galileo/galil eo_press/ 2002-01-30 11:02:26.204217500 Traceback (innermost last): 2002-01-30 11:02:26.204220500 File /web/Zope-2.4.3/lib/python/ZPublisher/Publish.py, line 175, in publi sh 2002-01-30 11:02:26.204223500 File /web/Zope-2.4.3/lib/python/Zope/__init__.py, line 240, in commit 2002-01-30 11:02:26.204226500 File /web/Zope-2.4.3/lib/python/Products/TransactionAgents/__init__.py, l ine 54, in new_commit 2002-01-30 11:02:26.204230500 File /web/Zope-2.4.3/lib/python/ZODB/Transaction.py, line 302, in commit 2002-01-30 11:02:26.204233500 File /web/Zope-2.4.3/lib/python/ZODB/Connection.py, line 324, in commit 2002-01-30 11:02:26.204346500 ConflictError: '\x00\x00\x00\x00\x00\x00\x00\x02' 2002-01-30 11:02:26.204349500 2002-01-30 11:02:26.204350500 2002-01-30 11:02:37.190244500 ------ 2002-01-30 11:02:37.190248500 2002-01-30T10:02:37 INFO(0) Z2 CONFLICT Competing writes at, /galileo/ssl/s uche 2002-01-30 11:02:37.190822500 Traceback (innermost last): 2002-01-30 11:02:37.190824500 File /web/Zope-2.4.3/lib/python/ZPublisher/Publish.py, line 175, in publi sh 2002-01-30 11:02:37.190827500 File /web/Zope-2.4.3/lib/python/Zope/__init__.py, line 240, in commit 2002-01-30 11:02:37.190830500 File /web/Zope-2.4.3/lib/python/Products/TransactionAgents/__init__.py, l ine 54, in new_commit 2002-01-30 11:02:37.190833500 File /web/Zope-2.4.3/lib/python/ZODB/Transaction.py, line 302, in commit 2002-01-30 11:02:37.190836500 File /web/Zope-2.4.3/lib/python/ZODB/Connection.py, line 324, in commit 2002-01-30 11:02:37.190851500 ConflictError: '\x00\x00\x00\x00\x00\x00\x00\x00' 2002-01-30 11:02:37.190853500 2002-01-30 11:02:37.190854500 2002-01-30 11:03:39.067913500 ------ 2002-01-30 11:03:39.067920500 2002-01-30T10:03:39 INFO(0) Z2 CONFLICT Competing writes at, /galileo/ssl/s hop/warenkorb/ 2002-01-30 11:03:39.070648500 Traceback (innermost last): 2002-01-30 11:03:39.070650500 File /web/Zope-2.4.3/lib/python/ZPublisher/Publish.py, line 175, in publi sh 2002-01-30 11:03:39.070653500 File /web/Zope-2.4.3/lib/python/Zope/__init__.py, line 240, in commit 2002-01-30 11:03:39.070656500 File /web/Zope-2.4.3/lib/python/Products/TransactionAgents/__init__.py, l ine 54, in new_commit 2002-01-30 11:03:39.070660500 File /web/Zope-2.4.3/lib/python/ZODB/Transaction.py, line 302, in commit 2002-01-30 11:03:39.070663500 File /web/Zope-2.4.3/lib/python/ZODB/Connection.py, line 324, in commit 2002-01-30 11:03:39.070681500 ConflictError: '\x00\x00\x00\x00\x00\x00\x00\n' 2002-01-30 11:03:39.070683500 2002-01-30 11:03:39.070684500 !tai 2002-01-30 11:04:11.248404500 ------ 2002-01-30 11:04:11.248411500 2002-01-30T10:04:11 INFO(0) Z2 CONFLICT Competing writes at, /galileo/galil eo_computing/ 2002-01-30 11:04:11.323482500 Traceback (innermost last): 2002-01-30 11:04:11.323488500 File /web/Zope-2.4.3/lib/python/ZPublisher/Publish.py, line 175, in publi sh 2002-01-30 11:04:11.323492500 File /web/Zope-2.4.3/lib/python/Zope/__init__.py, line 240, in commit 2002-01-30 11:04:11.323495500 File /web/Zope-2.4.3/lib/python/Products/TransactionAgents/__init__.py, l ine 54, in new_commit 2002-01-30 11:04:11.323498500 File /web/Zope-2.4.3/lib/python/ZODB/Transaction.py, line 302, in commit 2002-01-30 11:04:11.323501500 File /web/Zope-2.4.3/lib/python/ZODB/Connection.py, line 420, in commit 2002-01-30 11:04:11.323554500 (Info: (('BTrees.OOBTree', 'OOBTree'), '\x00\x00\x00\x00\x00\x00\x00\x0 3', '')) 2002-01-30 11:04:11.323557500 File /web/Zope-2.4.3/lib/python/Products/CoreSessionTracking/SessionStora ge.py, line 186, in store 2002-01-30 11:04:11.323561500 (Object: SessionStorage) 2002-01-30 11:04:11.323562500 ConflictError: ('\x03B`|"\xd2\x85\xbb', '\x03B`|+"\xdf*') We use LoginManager with some modifications made by Joachim Schmitz.

Odd wiki subscription behavior
by Gary Poster 31 Jan '02

31 Jan '02

I'm getting wiki emails from pages that I have absolutely no connection or subscription to: the two most recent were http://www.zope.org/Members/jeremy/CurrentAndFutureProjects/PerformanceMeasu rements and http://www.zope.org/Members/jeremy/CurrentAndFutureProjects/FastGlobals and I've gotten them over the past couple of days from some other projects too. Is this a "Zope bug" for the collector, or what? As in, how should I report this? Thanks Gary

indirection question
by Jeremy M. Smith 31 Jan '02

31 Jan '02

Hello-- I'm having a problem with indirection. I have a form object that has a header method. I also have a DTML method called showForm: <dtml-var "form.header()"> The problem is that the name of the form object that I'm calling is variable. From all of the Zope docs and howtos, _[var] should allow you to do indirection. I'm putting the actual name of the form object as a parameter to showFormm so this should work: <dtml-var "_[form].header()"> But this gives me an AttributeError of __hash__ error with the following traceback: Traceback (innermost last): File /usr/local/zope/lib/python/ZPublisher/Publish.py, line 223, in publish_module File /usr/local/zope/lib/python/ZPublisher/Publish.py, line 187, in publish File /usr/local/zope/lib/python/Zope/__init__.py, line 221, in zpublisher_exception_hook (Object: Traversable) File /usr/local/zope/lib/python/ZPublisher/Publish.py, line 171, in publish File /usr/local/zope/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: index_html) File /usr/local/zope/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: index_html) File /usr/local/zope/lib/python/OFS/DTMLMethod.py, line 189, in __call__ (Object: index_html) File /usr/local/zope/lib/python/DocumentTemplate/DT_String.py, line 540, in __call__ (Object: index_html) File /usr/local/zope/lib/python/DocumentTemplate/DT_Util.py, line 339, in eval (Object: showForm(form=dumbform)) (Info: showForm) File <string>, line 0, in ?

Don't delete your users without care...
by Florent Guillaume 31 Jan '02

31 Jan '02

Just a little near-death experience I had here... In a CMF site, thus in an acl_users not at the root, the CMF administrator had a Manager account. This administrator created all the site, skins, and so on. He also has an account at the root, with the same password. Now came the time for a cleanup, and deletion of the unneeded account in CMF. Then everything went weird, the site mostly worked but acquisition seemed to not find things, ZopeSecurityPolicy failed in validate (for instance if I put standard_html_header besides the object I accessed it worked, but if I left it in the skins it didn't)... It finally dawned on me that all the skins and so on were owned by the now nonexistent admin in the sub-acl_users, and that this caused all those problems. I re-added him. I probably could have "taken ownership" of all skins and CMF machinery from the admin at the root but I wanted to play it safe.

strip HTML-Tags
by Florian Fahrbach 31 Jan '02

31 Jan '02

Hi, I hope that somebody has a solution for my problem: I need to strip Html-Tags from a text in ZOPE which I want so send via E-Mail. I pass the text as a variable to a python script which looks like this: import re strip_html_pattern = re.compile(r'<[^>]*>') plaintext = strip_html_pattern.sub('',text) return plaintext But it doesn't work. The script asks for password and username, although it has the "manager"-role. Does anybody know a way that works? Perhaps there is a less difficult way of doing this (I tried to strip the tags in the dtml-document directly, but it didn't work also). Greetings F. Fahrbach -- GMX - Die Kommunikationsplattform im Internet. http://www.gmx.net

There is a way to do this, and that way is discussed in ZopeLabs (http://www.zopelabs.com/) Unfortunately, something is wrong with ZopeLabs. It is as though all the recipies in ZopeLabs were suddenly lost. As soon as ZopeLabs finds its head again, I would suggest looking there. They have (had) quite a few nice recipies there for day-to-day use of a Zope site.

ZCatalog inside ZClass - AttributeError when adding index
by Juergen R. Plasser / HEXAGON 31 Jan '02

31 Jan '02

Hi all, when I create a ZCatalog instance inside my ZClass container (as described in http://www.zope.org/Members/Zen/tips/tip_ZCatalogInZClass) I get an AttributeError. Here is snapshot of my code in the myclass_add DTML method: >>> <dtml-call "manage_addProduct['ZCatalog'].manage_addZCatalog('Catalog','','create_defa ult_catalog_',REQUEST)"> <dtml-with "Catalog"> <dtml-call "manage_delColumns(['summary',],REQUEST,RESPONSE,URL1)"> <dtml-call "manage_addColumn('test',REQUEST,RESPONSE,URL1)"> <dtml-call "manage_addIndex('test','FieldIndex',REQUEST,RESPONSE,URL1)"> </dtml-with> <<< The problem seems to be the manage_addIndex method. What am I doing wrong? When I change the given dtml-call into <dtml-call "manage_addIndex('test','FieldIndex',None)"> everything works fine. Am I missing something or is this the right way?
