While deploying local, db_driver.py raises exception "failed to open transaction: ' + e.message"

Hi, I try to deploy Rhizi locally, but it fails. I am not used to the configuration of neo4j (users, etc).

Config: rhizi-0.0.1-20150427-014900 neo4j-community-2.3.1

running:

ant -f ./build.ant deploy-local

ok

and modifed etc/rhizi-server.conf

sed '%user_db_path =% s%deploy-local/%%' etc/rhizi-server.conf

then:

cd deploy-local && python bin/rz_server.py --config-dir=etc

Log

2015-11-16 17:00:27,848 [INFO] rhizi user DB located, path: ./etc/user_db.db 2015-11-16 17:00:27,858 [INFO] rhizi user DB initialized: path: ./etc/user_db.db, user-count: 0 2015-11-16 17:00:27,867 [INFO] rhizi rz_kernel: on-line 2015-11-16 17:00:27,882 [ERROR] rhizi op: DBO_nop: tx-id: None Traceback (most recent call last): File "/opt/rhizi-0.0.1-20150427-014900/src/server/db_controller.py", line 39, in exec_op self.db_driver.begin_tx(op) File "/opt/rhizi-0.0.1-20150427-014900/src/server/db_driver.py", line 57, in begin_tx raise Exception('failed to open transaction: ' + e.message)

Inside src/server/db_driver.py, the exception raised is commented as follow:

[!] neo4j seems picky about receiving an additional empty statement list

Your help will be welcome!

Since some recent neo4j version the default is authentication required, but rhizi doesn't support that. So to turn off authentication (assuming this is the cause) set in neo4j-server.properties:

dbms.security.auth_enabled=false

thanks! but not finished

still in deploy-local/

failed to initialize server: 'Config' object has no attribute 'log_path' Traceback (most recent call last): File "bin/rz_server.py", line 435, in log = init_log(cfg) File "bin/rz_server.py", line 246, in init_log log_handler_f = logging.FileHandler(cfg.log_path) AttributeError: 'Config' object has no attribute 'log_path'

Do I add a value myself? (at this stage, I don't think about log files)

I notice that in bin/rz_server.py, there are both

config_dir at line 40: cfg['user_db_path'] = os.path.join(cfg['config_dir'], 'user_db.db')

and

cfg_dir at line 246

etc/rhizi-server.conf is empty!

I start again.

see run-local.sh - it copies the example config file for you if you did not do it yourself. If you prefer not to use it just follow it: cp res/etc/rhizi-server.conf.example res/etc/rhizi-server.conf
