Recommended practice for application exception handling in AngularJS
I was thinking about the same recently, and it occurred to me that when it comes to a good error handling in javascript, it is irrelevant which framework you are using, Angular on something else. I wrote one such error handler recently for an AngularJS project, but I did it in a way it can … Read more
How do Java 8 parallel streams behave on a thrown exception?
When an exception is thrown in one of the stages, it does not wait for other operations to finish, the exception is re-thrown to the caller. That is how ForkJoinPool handles that. In contrast findFirst for example when run in parallel, will present the result to the caller only after ALL operations have finished processing … Read more
Suppress panic output in Rust when using panic::catch_unwind
You need to register a panic hook with std::panic::set_hook that does nothing. You can then catch it with std::panic::catch_unwind: use std::panic; fn main() { panic::set_hook(Box::new(|_info| { // do nothing })); let result = panic::catch_unwind(|| { panic!(“test panic”); }); match result { Ok(res) => res, Err(_) => println!(“caught panic!”), } } As Matthieu M. notes, you … Read more

Idiomatic error handling in Clojure
Clojure error handling is generally JVM exception (unchecked) oriented. Slingshot makes using exceptions more pleasant by allowing, for example, destructuring on thrown exception values. For an alternative that allows erlang-style error handling you should look at dire. This blog post gives a good overview of the rational for dire as well as an overview of … Read more
Try Catch blocks inside or outside of functions and error handing
In general, an exception should only be caught if it can actually be handled. It makes no sense to catch an exception for no purpose other than to log it. The exception is that exceptions should be caught at the “top level” so that it can be logged. All other code should allow exceptions to … Read more
Is it okay that I sometimes sink my exceptions?
Yes, it is common, but in general it shouldn’t be done. There are exceptions like OutOfMemoryException which are better not caught, unless you catch them to attempt to terminate your application gracefully. In the majority of cases, swallowing System.Exception or System.SystemException will inevitably hide further run-time problems.
Exception handling in Google Go language [closed]
panic/recover is moral equivalent of try/catch exceptions. There is superficial difference (syntax) and a subtle, but important, difference of intended use. The best explanations of problems with exceptions in general is “Cleaner, more elegant, wrong” and that’s a good overview of pros/cons of exceptions vs. returning error codes. Go designers decided that error handling by … Read more
Does wrapping everything in try/catch blocks constitute defensive programming?
My basic rule is : Unless you can fix the problem which caused the exception, do not catch it, let it bubble up to a level where it can be dealt with. In my experience, 95% of all catch blocks either just ignore the exception (catch {}) or merely log the error and rethrow the … Read more
