Python writes the SVN update for automation

When executing the script on the remote machine, in order to guarantee the real-time script, we usually put the script on the SVN, the remote machine through the SVN operation to update the script;

The SVN update script can be implemented in just 2 steps, and this place uses the PYSVN library to see the implementation

# Initialize clientself.client = pysvn. Client () self.client.set_default_username (self.username) Self.client.set_default_password (Util.decrypt_des ( Self.password)) #更新代码self. Client.update (Self.localpath)

However, in the actual situation, there may be an update failure condition, after we increase the exception, re-checkout the operation, as follows

#判断更新是否成功

Revision = Nonetry:    revision = self.client.update (Self.localpath) except:    log.exception (traceback.format_ EXC ())    revision = Noneif not os.path.exists (Os.path.join (Self.localpath, ". SVN")):    revision = None

#更新失败, re-checkoutif revision is None or revision[0].number = =-1:

    .......

    Self.client.checkout (Self.url, Self.localpath)

Update exception generally this can be solved, if we are in a more complex environment, for example, some machines need to access SVN through a proxy, how to do it?

SVN through the proxy, the way is the configuration file, then we need to send the proxy server information as a file write to the configuration file, and then use the configuration file to initialize the SVN object, the code is as follows:

UseProxy = Util.get_prop ("proxy.enable") if useproxy! = "False":    self._init_servers (configdir)    self.client = Pysvn. Client (Configdir) Else:    self.client = pysvn. Client ()    self.client.set_default_username (self.username)    Self.client.set_default_password (util.decrypt _des (Self.password))

This will be OK ~ Finally attach all the code snippets

Agent () If "id" in kwargs:self.id = kwargs["id"] if "url" in Kwargs:self.url = Kwarg            s["url"] if "username" in kwargs:self.username = kwargs["username"] if "password" in Kwargs: Self.password = kwargs["password"] if "localpath" in Kwargs:self.localPath = kwargs["LocalPath" ] If "startversion" in kwargs:self.startVersion = kwargs["Startversion"] if "preversion" in Kwar Gs:self.preVersion = kwargs["Preversion"] def _init_servers (self, configdir): Proxyip = Util.get_pro        P ("Proxy.ip") ProxyPort = Util.get_prop ("Proxy.port") Proxyusername = Util.get_prop ("Proxy.username") Proxypwd = Util.get_prop ("Proxy.password") configstr = "[global]\r\n" "Http-proxy-host =%s\r\ N "" Http-proxy-port =%s\r\n "" HTtp-proxy-username =%s\r\n "" "Http-proxy-password =%s"% (Proxyip, ProxyPort, Proxyusername, proxypwd ) Serversfilepath = Os.path.join (Configdir, "Servers") Serverfile = Codecs.open (Serversfilepath, "w", "Utf-8 ") Serverfile.write (CONFIGSTR) serverfile.close () def init (self): Self.localpath = Util.get_act_st R (Self.localpath, self.agent.envDict) Configdir = Os.path.join (Tempfile.gettempdir (), "PYSVN") if not Os.pat H.exists (Configdir): Os.makedirs (configdir) UseProxy = Util.get_prop ("proxy.enable") if UseProxy ! = "False": Self._init_servers (configdir) self.client = pysvn.
