Description
Simple test Python program will seg fault when using CBS 7.0 and using actual scopes/collections (i.e. not default_collection()). Looking into the bindings (see gdb output below), it looks to happen because the lcb_respstore_error_context() method is not populating the scope and collection information correctly. I did find that if I build the Python client w/ LCB commit f8ccaa1c660c4967d47bda94398b2eeefc4e0607, I do not have this problem. Using CBS 7.0.0-5219 build.
Please let me know if I am missing a change in the LCB API, or if further info should be provided.
Python sample code.
from couchbase.cluster import Cluster, ClusterOptions |
from couchbase.auth import PasswordAuthenticator |
import faulthandler |
|
|
cluster = Cluster('couchbase://localhost', |
ClusterOptions(PasswordAuthenticator('Administrator', 'password'))) |
bucket = cluster.bucket('default') |
scope = bucket.scope('test-scope') |
coll = scope.collection('test-collection') |
|
|
print(cluster.lcb_version()) |
faulthandler.enable()
|
coll.insert('test', {'info': 'this is a test'}) |
