[Zope-dev] Unexpected Behaviour iterating over catalog search...

[Chris Withers]

Hi,

I have something like this:

for brain in Catalog(some_index=some_value):
     # delete the object, and then
     Catalog.uncatalog_object(brain.getPath())

...which wasn't deleting all objects where some_index=some_value.

On a hunch, I tried:

for brain in tuple(Catalog(some_index=some_value)):
     # delete the object, and then
     Catalog.uncatalog_object(brain.getPath())

...which magically worked.

Surely the thing returned by a Catalog search should be immutable?

cheers,

Chris
