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)
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)
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>

<pidfile>uwsgi_bfdds.pid</pidfile>
<stats>127.0.0.1:3457</stats>

</uwsgi>
