Re: Potential PythonScript bug (was: Re: [Zope] question about manipulating zcatalog query results)

[Ira Sher]

Dieter,
thanks. I'll take a look at that now. The folks at bug collection are
unable to reproduce the bug on 2.7.5, though, and so we're trying to
determine how else it might be occuring--Products would be my best
guess, as the Product list has changed (many are obsolete or simply
don't run on 2.7.5 when migrating from 2.5.1 (with products that have
been left on since 1.x...ug). The last version I had it running stably
on was 2.6.3, locally, and of the several products that have been
migrated out since then, PluginIndexes and ZCTextIndex I can't grab
from cvs (the versions I have crash the startup) as I get a 4k empty
tarball downloading with any browser...don't know if these should be
obsolete, too.

take care and thanks again for the suggestions
ira

The strange thing is that I can do:

return [o.id for o in container.Catalog()]

without a problem.

However, I am still using Zope 2.7.2 -- the version
before the last security shakeup...


If your script does not need security checks, than
my "TrustedExecutables" might help you. It provides
"PythonScript"s without any security restrictions -- and
especially without the need for "_getiter_".

Re: [Zope] question about manipulating zcatalog query results

[Ira Sher]

Dieter,
I actually put the list in because one of the last suggestions in the
archives to repair the problem had to do with enclosing the assignment
in a list. The original code was essentially:
if sorton == 'id':
res=[(row.id.split().pop(), row) for row in results]
res.sort()
return res

This doesn't work, either, in zope 2.7.4 or 2.7.5 with python 2.3.4
and 2.3.5 respectively, as far as I can see.

Thanks for taking a look at things--I'll file a bug report (this is
stopping me from migrating a site into 2.7) as you suggested

Nobody mentioned it again -- until your report...

You may try to remove the "list(...)" wrapping in your code.
It should work without.

If it does not, file a bug report to "http://www.zope.org/Collectors/Zope";.

Re: [Zope] question about manipulating zcatalog query results

[Ira Sher]

I scoured the archives, and found mention of this problem, and a note
by you, Dieter saying it was a problem with the 2.7 beta (this was
back in May of 2004) but I can't find any subsequent mention of the
issue, and the problem I'm having is on both a 2.7.4 and a 2.7.5
build.

thanks

I remember to have seen reports in the mailing list -- together
with a report that the problem was fixed.

Re: [Zope] question about manipulating zcatalog query results

[Ira Sher]

Chris, the relevant section of the script looks like this:

zcat=context.Catalog
if spontype == 'none':
results = zcat(meta_type=mtype)
else:
results = zcat(meta_type=mtype,SB_sponsor_type=spontype)
if sorton == 'id':
res = []
rest = []
res = list(results)
for row in res:
rest.append(row.id.split().pop(), row)
rest.sort()
return rest

this keeps garnering the 'global name _getiter_ is not defined under
2.7.5'...as you can see, the results have been transfered to a new
list, so I'm not even looping and splitting the original query results
(this was originally a much briefer script, but I've broken it down to
see where exactly things were hanging up). If I pull the loop, or use
a while loop and simply asign values from res to rest, then everything
works fine, but as soon as I use that for loop, I get the _getiter_
error, and using split with the while loop (looks like:

j = 0
while j < len(res):
k = res[j]
kk = k.split().pop()
rest.append(kk)
j = j+1


) I get AttributeError: split, or in the case of trying to play with
the k string pulled from the list (by adding additional text, for
example) I get "Record objects do not support concatenation". I just
can't see a way to play with the zcat query results without raising an
error, and I'm dreadful confused...

thanks again for looking into this

Re: [Zope] question about manipulating zcatalog query results

[Ira Sher]

Chris,
a traceback for a script (testy in this case, called from
testyer_html, as I've broken out the problem area and have been trying
to work around it) using a for loop on a zcatalog result looks like:

*  Module ZPublisher.Publish, line 101, in publish
* Module ZPublisher.mapply, line 88, in mapply
* Module ZPublisher.Publish, line 39, in call_object
* Module OFS.DTMLMethod, line 144, in __call__
  
  URL: http://www.sarabandebooks.test/testyer_html/manage_main
  Physical Path:/sarabande/testyer_html
* Module DocumentTemplate.DT_String, line 474, in __call__
* Module DocumentTemplate.DT_In, line 626, in renderwob
* Module DocumentTemplate.DT_Util, line 198, in eval
  __traceback_info__: testy
* Module , line 1, in 
* Module Shared.DC.Scripts.Bindings, line 306, in __call__
* Module Shared.DC.Scripts.Bindings, line 343, in _bindAndExec
* Module Products.PythonScripts.PythonScript, line 302, in _exec
  __traceback_info__: ({'traverse_subpath': [], 'container':
, 'context': ,
'script': }, ('Author', 'id',
'none'), {}, None)
* Module Script (Python), line 16, in testy

NameError: global name '_getiter_' is not defined

There is no call to _getiter_, of course, in the script, but whenever
I use any for looping on the results, I get a variation of the above.

Any thoughts on this?

thanks again,
ira
