The error here is explicitly handled, and cannot be accidentally ignored. Unlike golang where it's quite easy for errors to go ignored accidentally.

Nevertheless, this is how it is mostly done in Java. I haven't used eclipse in eons, but last time I did it even generated this code.

If you care with go, use errcheck.

Does errcheck work well with gorm (https://gorm.io/) and it's way of returning errors? This is not an obscure library, it's quite widely used.

Does any language save you from explicitly screwing up error handling? Gorm is doing the Go equivalent of:

     class Query {
         class QueryResult {
             Exception error;
             Value result;
         }
         public QueryResult query() {
             try {
                 return doThing();
             } catch(Exception e){
                 return new QueryResult(error, null);
             }
         }
     }

Gorm is going out of its way to make error handling suck.

It's about the default error handling method being sane. In exception based languages, an unhandled error bubbles up until it reaches a handler, or it crashes the program with a stacktrace.

Compare to what golang does, it's somewhat easy to accidentally ignore or overwrite errors. This leads to silent corruption of state, much worse than crashing the program outright.

Gorm isn't using the default error handling.

[apta]

That's one point in this discussion. The language allows error handling that way. Compared to a language with proper sum types or exceptions, where one would have to actively work against the language to end up with that mess.

[hactually]

because it has try/catch. Without that (which would be similar to not checking the err in go) it explodes or throws to a layer up that may not expect it.

Each language has its wonks.

It's not similar to that at all. Without it, the exception bubbles up until it gets caught somewhere, or crashes the program with a useful stacktrace.

With golang, it just goes undetected, and the code keeps running with corrupt state, without anyone knowing any better.
