"Step over/next" command often performs "continue" in ruby 2.6

@rockorequin Could you provide a sample script to reproduce the problem?

[rockorequin]

This script shows the problem for me: with 2.6.3p62, if I put a breakpoint on the line "k = DateTime.parse..." line and then do a 'next' when it hits that line, instead of stopping on the "puts" line, the code stops at ruby-debug-ide.rb#101, ie the line saying: if bt && !bt.is_a?(SystemExit).

require 'rails'

class Test
  def a
    k = DateTime.parse('2019-1-1').to_date.end_of_day
    puts "Hello!"
    k + 1.day
  end
end

j = Test.new.a

@ViugiNick Did you have any luck reproducing this?

[rockorequin]

Fwiw, I tried ruby 2.7.0-preview1 and it seems that it doesn't have this problem, so maybe it's a bug in the underlying ruby-2.6 tracepoint API.

@rockorequin looks like you are right. Are you ok with using 2.7.* or should I try to fix this for 2.6.*?

[rockorequin]

@ViugiNick Personally I'm fine with using 2.7 for now or I can go back to 2.5 if 2.7 breaks something down the line. Perhaps it could be noted as a known issue with 2.6 in the readme?

I think the byebug maintainer figured out the issue with 2.6, and 2.6.4 might fix:

I can confirm. I just upgraded from 2.6.3 to 2.6.5 and the problem with debase and "step over" is gone. I think this issue can be closed :)
