所以关于这个问题的doozie的精彩低点:
简短版本: 我们正在为我们正在使用的这个软件项目构建一个分发系统。基本上我们取出构建工件,将其存储在ftp服务器上,该服务器将其传递给多个客户端,这些客户端执行脚本来修补其服务器。
长版:
1个分发服务器
多个客户端服务器
软件: jython 2.5.1, 蚂蚁1.8.0, pyro 3.10
分发服务器上运行了FTP服务器和PYRO客户端。每个客户端服务器都在其上运行PRYO服务器。
当PYRO客户端被告知启动补丁程序时,它会读取包含所有客户端服务器列表的计算机列表。然后逐个连接到每个PYRO服务器并执行修补程序。过程是:getPatch(获取该服务器的最新补丁),StopServer(停止可能或可能不会访问需要修补的软件的软件),应用补丁,StartServer。每个进程调用一个ANT脚本,该脚本通过一些文件夹名称和其他配置传递。当您开始应用补丁时,会发生有趣的部分。请参阅下面的错误日志。由于NDA原因,我不得不删除文件夹名称。
这是有趣的地方。分别运行程序的每个部分。即手动一次运行一个getPatch,StopServer等。这个错误不会发生。物理地进入机器并运行它不会发生的过程。只有当我们一个接一个地调用所有4个进程时。它发生在ApplyPatch阶段,当在多个文件上调用ANT替换脚本时。我们认为它可能与JVM保持文件一瞬间或2有关。但是这应该根据关于ant的bug注释进行修补。
简而言之:
分发服务器==> jython ==> pyro连接==>客户服务器==> jython ==>蚂蚁脚本

答案 0 :(得分:1)
似乎FTP就是问题所在。它通过jython在各个文件夹上保持锁定。因此,当引入新文件时,它会将其锁定为不可删除状态。您仍然可以编辑该文件,即在其上运行替换脚本。但是你不能删除它。 开始研究ftp的不同实现。即使用java / jython的版本而不是ant。
