python zookeeper 在 uwsgi中 watcher不生效

def code_watcher(handle,type, state, path):

    print "zk code watcher,path is: ",path

#data = zk.get(settings.ZKPATH_CODE,code_watcher)

    data = zookeeper.get(zk,settings.ZKPATH_CODE,code_watcher)

    code_json = json.loads(data[0])

    with open("./code_by_client.py",'w') as f:

        for line in code_json:

            f.write(line+'\n')

    reload(code_by_client) 





def generate_client_code():

    print "zk code,path is: ",settings.ZKPATH_CODE

#data = zk.get(settings.ZKPATH_CODE,code_watcher)

    data = zookeeper.get(zk,settings.ZKPATH_CODE,code_watcher) 

    code_json = json.loads(data[0])

    with open("./code_by_client.py",'w') as f:

        for line in code_json:

f.write(line+'\n')

原因是uwsgi没有开启多线程，而我们调用的zookeeper.so是需要多线程的。

修改uwsgi配置，加上一行 <enable-threads>1</enable-threads>，如下，

<uwsgi>

  <!--

  <cluster>225.1.1.1:3333</cluster>

  <socket>192.168.60.*:3031</socket>

  <http>127.0.0.1:3031</http>

  -->

  <http>192.168.61.89:3456</http>

  <pythonpath>../</pythonpath>

  <module>service</module>

  <master>1</master>

  <processes>4</processes>

  <disable-logging />

  <daemonize>logs/uwsgi_bfdds.log</daemonize>

  <buffer-size>16384</buffer-size>

  <harakiri>5</harakiri>

  <pidfile>uwsgi_bfdds.pid</pidfile>

  <stats>127.0.0.1:3457</stats>

  <enable-threads>1</enable-threads>

</uwsgi>
