simple zookeeper c++ bindings, zookeeper service monitor implemented via zookeeper c++ bindings. https://github.com/satanson/zk

Zk is built on conditions as follows:

1. zookeeper 3.4.3 and 3.4.8
2. g++ 4.8.4 (c++11 option enabled)

I don't build zk on other versions of zookeeper and g++.

ZK can be grasped in fews steps!

1. download zookeeper-3.4.8 and build c bindings of zookeeper

    $ wget  https://mirrors.tuna.tsinghua.edu.cn/apache/zookeeper/zookeeper-3.4.8/zookeeper-3.4.8.tar.gz
    $ tar xzvf zookeeper-3.4.8.tar.gz
    $ cd zookeeper-3.4.8/src/c
    $ ./configure && make && sudo make install
   

2. build zk demos

    $ ./build.sh
    $ ./zk_test -help
    $ ./zk_test 172.17.0.2:2181 /foobar
   
    $ ./build_zksm.sh
    $ ./zksm_test -help
    $ ./zksm_test 172.17.0.2:2181 /foobar
   

A standalone zookeeper instance or a zookeeper cluster should be started when trying zk_test and zksm_test. If you familiar with docker, image jplock/zookeeper can be played with for testing.

API manual You can learn how to use zk from demos(zk_test.cpp, zksm_test.cpp), which is quit easy!

1. Zookeeper ctor: establish connection to Zookeeper cluster and create a session.

ZooKeeper(string const& connStr, int sessionTimeout,shared_ptr<Watcher> watcher)

override Watcher's virtual function void process(WatchedEvent &const)

2. zk_create: create znode.

string zk_create(string const& path,string const& data,CreateMode createMode)

3. zk_delete: delete znode.

void zk_delete(string const& path,int version)

4. zk_exists: test if znode exists.

bool zk_exists(string const& path, bool watch)

5. zk_getData: fetch data from znode.

string zk_getData(string const& path, bool watch)

6. zk_setData: store data into znode.

void zk_setData(string const& path, string const& data, int version)

7. zk_getChildren: get znode's children.

list<string> zk_getChildren(string const& path,bool watch)
