Hi, I'm trying to iterate over all the comments in my discussion .fs
and I'm getting different errors each time. The latest is Memory Error (direct
fs access), sometimes it's trouble starting a thread (access through ZEO.)
I'm running ZODB 3.3 on a FreeBSD system.
I've tried doing periodic commit() and cacheGC(), but the memory use just keeps
growing until things blow up.
My question is: How can I get my zodb client to forget objects very shortly
after I read them? (I'm just counting objects, and want to get them out of
memory right away.)
I don't think I can del object because that would also remove it from the
database... isn't that correct?
my main loop is below...
Thanks,
-Jim
for groupid, group in db.group_db.root.items():
group_short_name = group.get_user_id()
# touch each discussion once
for item in group.get_blog().get_items():
for comment in item.get_all_comments():
author_id = comment.author.get_user_id()
counts[author_id] = counts.get(author_id, 0) + 1
transaction_commit()
db.connection.cacheGC()
print "counted in ", groupid
