Execution Continues After Exception Occurs In Evaluator

Answered

Created January 18, 2023 22:19

While debugging a script, if I evaluate an expression in the Evaluator window, and the expression throws an exception, then script execution continues. I would expect the script to remain at the debug point. Is there a setting I can toggle somewhere to fix this?

An example exception: my_variable is NOT defined. If I execute puts my_variable in the evaluator, the expression fails as expected; but then script execution continues, which is not expected.

This issue began to show up after I upgraded from jruby 9.3.4.0 to jruby 9.4.0.0.

I am using RubyMine 2022.3.1.

Hello,

I tried to reproduce it in RubyMine 2022.3.1 with the same jruby-9.4.0.0, but didn't manage to. Here's the sample code I used

p 'begin'
my_variable # breakpoint here
p 'continue after exception'

So I stopped on the breakpoint and tried to evaluate `my_variable`, but the debugger didn't resume, just showed that the variable is undefined.

My debug gems were ruby-debug-ide 0.7.3 + ruby-debug-base 0.10.7. Please let me know if your steps were the same.

Thanks for your reply.

I have one difference in my code, using the example you provided. I try to print my_variable to console, and run that line in the evaluator:

p 'begin'
p my_variable # breakpoint here
p 'continue after exception'

I also noticed that 'continue after exception' was not printed out, but instead the exception and stacktrace were output, and execution stopped as in a failure. Here is the output:

I tried the same, but in the evaluation console I placed `my_variable` only. Would it be possible to record a screencast showing your steps?

Oh I see, in the evaluation console, you have to put `p my_variable`. Let me know if that changes anything. If not, I will look into recording a screencast.
