[Zope] Cyclic garbage collection todo 2.9.3 onwards, fixed?
Hi All, Could anyone advise whether this has been fixed in any of the Zope versions beyond v2.9.3: To-do: * Add cyclic-garbage collection support to C extension classes, especially to acquisition wrappers. I don't see any mention of it at all after Zope 2.9.4 in the changes.txt.

[Zope] Multiple conditions inside tales

[Zope] Check Zope status
Hi All, Were having a few problems with our Zope server, it seems to be crashed but were not sure whether it is actually crashed or merely waiting (a long time) for a response from LDAP to authenticate our users, which may be causing it to hang. Is there any tool we can use to test to see if Zope has actally crashed?

First thing to do is use ps to see if there are any zope-related python processes running. For example: $ ps wax | grep python | grep ope On my gentoo workstation, I'm running both zope and zeo currently, so I get: 9609 ?S 0:05 /usr/local/bin/python /home/pw/z29soft/lib/python/Zope2/Startup/run.py -C /home/pw/z29inst/etc/zope.conf 9610 ?S 0:01 /usr/local/bin/python /home/pw/z29soft/lib/python/ZEO/runzeo.py -C /home/pw/z29inst/etc/zeo.conf If there are no processes, zope is obviously not running at all :) If there are processes but zope is not responding, first thing I would do is check the end of the zope event log and request log. That would help narrow down the time at which problems started. http://zopewiki.org/Z2Log http://zopewiki.org/EventLog Then, try GDB to figure out what zope is doing. http://www.upfrontsystems.co.za/Members/jean/zope-notes/debug-spinning-zope And, to make life easier next time, install http://www.zope.org/Members/nuxeo/Products/DeadlockDebugger finally, another tool that can help diagnose apparent hangs is the trace log, formerly known as the big M log. http://zopewiki.org/TraceLog -- Paul Winkler http://www.slinkp.com ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev ) ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

RE: [Zope] Nested dtml tags
Hmm, this doesn't appear to work. Let me explain what I'm trying to do. I have a Z SQL Method called selectmoduleinfoMethod that contains the SQL: SELECT * FROM RECMGR_EL_MODULE_Query WHERE MODCODE = dtml-sqlvar MODCODE type=string This recordset is returned to a dtml form to populate the fields ready for editing. One of the database table entries returned from this query is the value of MODLEVEL, this modlevel can be one of seven choices that appear in a select list. However I'd like the one returned from the database to appear as selected in the form for editing. As far as I can see the example you gave me does not retrieve the value of MODLEVEL from the returned SQL recordset it only checks for its existence and consequently cannot test for the conditions.

MODCODE type=string
You should never use SELECT * in production code. Better state the
name of the columns you really want there. (Thus fixing their name)
One simple form would be:
SELECT modlevel,modname,modlevel=dtml-sqlvar modlevel as selected
FROM foobar WHERE modcode = dtml-sqlvar modcode type=string ...
Then you could use the result of your ZSQL Method more or less directly,
in ZPT for example:
select name=MODLEVEL (size=1 is default anyway ;)
option tal:repeat=mod here/yourZSQLMethod
tal:attributes=value mod/modlevel; selected mod/selected
tal:content=mod/modname123/option
/select
In Python Script, it should work like this:
MODLEVEL=request.form.get('MODLEVEL','') # make sure you get the types
correctly
return [dict(x,selected=x.modlevel==MODLEVEL) for x in
context.selectmoduleinfoMethod()]
this works with your ZSQL method as it is (more or less - adjust the column
names)
and can be used like the one above.
If you like ugly templates and a lot of writing you can translate the
example to DTML - this is left to the reader ;)

Tino

[Zope] Render DTML inslide ZPT slot
Hi All, Is it possible to render DTML methods inside a slot of a ZPT? If so, how would I achieve this?

[Zope] How to convert characters that have special meaning in HTML to HTML character entities
Hi All,
I have a string that contains a a
href=http://www.mywebaddress.com;link/a tag that I would like rendered
as HTML when output but it only seems to render in the html page like this
lt;a href=http://www.mywebaddress.comgt;linklt;/agt;
To replace the characters, I tried this in my TAL:
tal:block tal:define=d_stand row/STANDFIRST | nothing;
d_stand_replaced_chars python: (str(d_stand)).replace('gt;','');
p tal:condition=d_stand_replaced_chars
tal:content=d_stand_replaced_chars /
/tal:block
But it converted the 'gt;' I replaced with a '' back to a 'gt;' upon
rendering the string in a html page.
Any ideas how I can achieve this?

RE: [Zope] Memory Leak Debugging
Hi All, A few weeks ago I posted this message to the list but we still haven't resolved our memory leak, mainly because we have no idea where to look. So having trawled around a few forums I decided to install the LeakFinder product onto our development server and click around a little watching the refcounts. Here I noticed that Products.Silva.Image.Image DateTime.DateTime.DateTime had the largest number of references. So following the LeakFinder instructions I attempted to patch each of these classes. I started with the Products.Silva.Image.Image class and continued to click around to return some results, unfortunately this never returned any results at all so that wasn't much help. Next I patched the DateTime.DateTime.DateTime class which returned a huge amount of information on the results tab. So I'm now hoping someone could help me in deciphering these results and explain what exactly should I be looking for here? And it would also be useful to know why the Products.Sivla.Image.Image class doesn't return any results at all. Hope someone can help.
