The socket should be held and closed as close to the consumer of the port as possible since otherwise, there is a greater chance of race-condition where a different process may see the port as being free and take it.

Starts and stops a local standalone etcd server on a random free port. Useful for single node, multi-worker launches or testing, where a sidecar etcd server is more convenient than having to separately setup an etcd server. This class registers a termination handler to shutdown the etcd subprocess on exit. This termination handler is NOT a substitute for calling the ``stop()`` method. The following fallback mechanism is used to find the etcd binary: 1. Uses env var TORCHELASTIC_ETCD_BINARY_PATH 2. Uses ``/bin/etcd`` if one exists 3. Uses ``etcd`` from ``PATH`` Usage :: server = EtcdServer("/usr/bin/etcd", 2379, "/tmp/default.etcd") server.start() client = server.get_client() # use client server.stop() Args: etcd_binary_path: path of etcd server binary (see above for fallback path) Nrcd|_d|_tjj t }tjj |d}tjjd||_ tjj|jsd|_ |r|ntjd|_ d|_d|_y)Nrzbin/etcdTORCHELASTIC_ETCD_BINARY_PATHetcdtorchelastic_etcd_data)prefix)_port_hostospathdirname__file__joinenvironget_etcd_binary_pathisfiletempfilemkdtemp_base_data_dir _etcd_cmd _etcd_proc)selfrrootdefault_etcd_bins r__init__zEtcdServer.__init__ns   wwx(77<<j9!# +-=" ww~~d445%+D "!Hh&6&6>V&W 6:r+returncH|js td|jS)Nz>No etcd server process started.

When this function returns the sever is ready to take requests. Args: timeout: time (in seconds) to wait for the server to be ready before giving up. num_retries: number of retries to start the server. Each retry will wait for max ``timeout`` before considering it as failed. stderr: the standard error file handle. Valid values are `subprocess.PIPE`, `subprocess.DEVNULL`, an existing file descriptor (a positive integer), an existing file object, and `None`.
