Make R exit with non-zero status code

由 浪子不回头ぞ 提交于 2020-01-19 03:10:47
问题 I am looking for the R equivalent of linux/POSIX exit(n) which will halt the process with exit code n, signaling to a parent process that an error had occurred. Does R have such a facility? 回答1: It's an argument to quit() . See ?quit . Arguments : status: the (numerical) error status to be returned to the operating system, where relevant. Conventionally ‘0’ indicates successful completion. Details : Some error statuses are used by R itself. The default error handler for non-interactive use

问题 NativeApplication.nativeApplication.exit() does not seem to work on IOS and I'm in a position where if a certain error code is I'd like to either be able to shutdown and restart my applicaiton. 回答1: You are not able to shut down and then restart your application on iOS. You can quit your app, but not restart. 回答2: You can't ( as far as I know ) exit an iPad application, but you can crash it! There's other ways of going about it, but the general idea is to keep taking more memory until iOs

What's the best way to register a function to run during an unexpected exit of a Rust program?

问题 I'm creating a terminal text editor in Rust. The editor puts the terminal into raw mode, disabling character echoing and the like, and then restores the original terminal function upon exit. However, the editor has some bugs, and crashes unexpectedly every now and again due to issues like unsigned variable underflow. When this happens, the cleanup code which would restore the terminal to its original state never runs. The cleanup function I'd like to run is the following: fn restore_orig_mode

java out of memory then exit

问题 I have a piece of software that has to analyze big files. Constraining the input or giving infinite memory is not an option, so I have to live with flying OOMEs. Because the OOME only kills the Thread, my software runs in some crappy state. From outside everything looks okay because the process is running but on the inside it's braindead. I would like to pull the plug on it. But how can I do this? Catching a OOME does not guranteee that the next line of code will be executed. e.g System.exit

Container killed on request. Exit code is 143

背景 只是一条INSERT语句插入一条数据，然后就报错 报错如下 Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.tez.TezTask 分析 之前写过这个错误，这只是个表象错误，具体问题还是需要看日志分析。Z 正常日志里没有报错，在这个任务的一个POST日志文件中发现如下报错 Container container_e19_1577953713473_0001_01_000003 exited with diagnostics set to Container failed, exitCode=-105. Container killed by the ApplicationMaster. Container killed on request. Exit code is 143 Container exited with a non-zero exit code 143 因某种原因通过度娘无法找到exitCode=-105的相关，只能找到Exit code is 143的相关问题。大部分都是在说是yarn的container分配的内存不够，需要进行yarn资源调整。但是详细的可以看到具体报错就是内存问题的报错，跟自己遇到的并不是同一种情况。 还是回过头来分析语句，因为是往特定的一个分区插数
