Hi Sanket -
Could you please try *removing* the precommit hook from the "uuid_log"
bucket and define it on the "test_kv_wo" bucket type instead?
Removal:
curl -4vvv -H 'Content-Type: application/json' -X PUT
localhost:8098/types/test_kv_wo/buckets/uuid_log/props -d
'{"props":{"precommit":[]}}'
Confirm:
curl -4vvv localhost:8098/types/test_kv_wo/buckets/uuid_log/props
Add precommit hook to bucket type:
curl -4vvv -H 'Content-Type: application/json' -X PUT
localhost:8098/types/test_kv_wo/props -d
'{"props":{"precommit":[{"mod":"precommit","fun":"pre_uuid"}]}}'
Confirm:
curl -4vvv localhost:8098/types/test_kv_wo/props
You can then use redbug to trace calls within Erlang:
riak attach
The following statement will wait for up to 10 minutes and will
display up to 10 calls to your pre_uuid function. Note that the period
is significant:
redbug:start(600000, 10, "precommit:pre_uuid/1->return").
If you run the above redbug statement on all nodes, you should see one
or more outputs showing that it was called. You can confirm that
redbug is working by tracing calls to now():
redbug:start("erlang:now/0").
