Issue #19003 has been updated by ko1 (Koichi Sasada). Sorry for late. We left this issue as an implementation details and on Ruby 3.2 the current behavior will be remain. Sorry for inconvenient for your purpose. The reason is to implement the proposed behavior strictly needs a much work and we can't do that now. In my opinion the proposal behavior is preferable, so it can be fixed in future. BTW on the debug.gem we avoid duplicated TracePoint manually. ---------------------------------------- Bug #19003: TracePoint behavior inconsistency in 3.2.0-preview2 https://bugs.ruby-lang.org/issues/19003#change-100388 * Author: hurricup (Alexandr Evstigneev) * Status: Open * Priority: Normal * ruby -v: ruby 3.2.0preview2 (2022-09-09 master 35cfc9a3bb) [x86_64-linux] * Backport: 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN ---------------------------------------- This is kind of continuation of my previous report about global/local TP processing (#18730). Sample script: ```rb def foo return 1 end puts RubyVM::InstructionSequence.of(method :foo).disasm def step_over TracePoint.new(:line, :return, :b_return) do |tp| puts "Step over hits by #{tp.event} at #{tp.lineno}" step_over tp.disable end.enable(target: RubyVM::InstructionSequence.of(method :foo), target_thread: Thread.current) end TracePoint.new(:line, :return, :b_return) do |tp| if tp.lineno == 2 puts "Step into hits by #{tp.event} at #{tp.lineno}" step_over tp.disable end end.enable(target_thread: Thread.current) a = foo ``` In ruby 3.1.2 we have expected behavior. Output: ``` == disasm: #<ISeq:foo@/home/hurricup/Projects/ruby-debugger/jb-debase-30/test_sample.rb:1 (1,0)-(3,3)> (catch: FALSE) 0000 putobject_INT2FIX_1_ ( 2)[LiCa] 0001 leave ( 3)[Re] Step into hits by line at 2 Step over hits by return at 3 ``` In ruby 3.2.0-preview2 - not so much. Output: ``` == disasm: #<ISeq:foo@/home/hurricup/Projects/ruby-debugger/jb-debase-30/test_sample.rb:1 (1,0)-(3,3)> (catch: false) 0000 putobject_INT2FIX_1_ ( 2)[LiCa] 0001 leave ( 3)[Re] Step into hits by line at 2 Step over hits by line at 2 Step over hits by return at 3 ``` -- https://bugs.ruby-lang.org/
