shelve seg error

[Philippe C. Martin]

Hi,

I just installed (compiled) Python 2.4.2 under Suse 10.

The following code generates a seg error:

import shelve
print shelve.open ('test')

I assume this has to do with the db behind shelve.

How do I go about tracing/fixing the problem ?

Regards,

Philippe

PS:

This code however works, which seems to me means the problem is with the
default database used by shelve ... which one is it ?
import shelve
import gdbm

def gdbm_shelve(filename, flag="c"):
return shelve.Shelf(gdbm.open(filename, flag))

db = gdbm_shelve("dbfile")
Regards,

Philippe

the page says

If the database file already exists, the whichdb module is used to determine its
type and the appropriate module is used; if it does not exist, the first module
listed above that can be imported is used

where "above" refers to the list

dbhash (requires bsddb), gdbm, or dbm. If none of these modules is installed,
the slow-but-simple implementation in module dumbdbm will be used.

so the culprit in your case is either whichdb itself, or dbhash/bsddb...

OK, Thanks
