问题 In Java, is there a way to know that a StackOverflow error or OutOfMemory exception may happen soon? The OutOfMemory exception might be an easier one to catch, if one is capable of getting memory usage statistics programmatically, and if one knows ahead of time how much memory needs to be used before the OutOfMemory exception is thrown. But are those values knowable? For the StackOverflow error, is there a way to get recursion depth, and how does one know what value for recursion depth would

问题 I encountered an issue when I was using Task.Factory.StartNew and tried to capture an exception that is thrown. In my application I have a long running task that I want to encapsulate in a Task.Factory.StartNew(.., TaskCreationOptions.LongRunning); However, the exception isn't caught when I'm using Task.Factory.StartNew . It is however working as I expect when I use Task.Run , which I thought was just a wrapper on Task.Factory.StartNew (according to for instance this MSDN article). A working

问题 How can I programmatically add issues on my Github repository using C#? I have an Error Handler library (ErrorControlSystem) to attach that in a win application to raise that exceptions on a SQL table. Now, I want to store ErrorControlSystem self exceptions without the target app exceptions on self Github repository issues. How to can I do it? 回答1: You can use the GitHub API for that. Create a webhook and add an issue the following way: POST /repos/:owner/:repo/issues Example from https:/

问题 Evaluating, max_val = max(a) will cause the error, ValueError: max() arg is an empty sequence Is there a better way of safeguarding against this error other than a try , except catch? a = [] try: max_val = max(a) except ValueError: max_val = default 回答1: In Python 3.4+, you can use default keyword argument: >>> max([], default=99) 99 In lower version, you can use or : >>> max([] or [99]) 99 NOTE: The second approach does not work for all iterables. especially for iterator that yield nothing

问题 I'm using TypeScript for a reasonably large project, and am wondering what the standard is for the use of Error s. For example, say I hand an index out of bounds exception in Java: throw new IndexOutOfBoundsException(); Would the equivalent statement in TypeScript be: throw new Error("Index Out of Bounds"); What other ways could I accomplish this? What is the accepted standard? 回答1: Someone posted this link to the MDN in a comment, and I think it was very helpful. It describes things like
