Issue #19368 has been reported by luke-gru (Luke Gruber). ---------------------------------------- Bug #19368: Ractor.make_shareable issue/inconsistency when proc has been run that acesses outers through eval https://bugs.ruby-lang.org/issues/19368 * Author: luke-gru (Luke Gruber) * Status: Open * Priority: Normal * Backport: 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN ---------------------------------------- ``` a = Object.new # non-shareable prok = Ractor.current.instance_eval do Proc.new do eval('a') end end prok.call # this should work, we're in the main ractor and the proc is not isolated Ractor.make_shareable(prok) # this doesn't currently work, but I think it should. It gives Ractor::IsolationError. See below for reasoning on why I think it should work. # A flag seems to be set on the proc after it's run and accesses outers... ``` Because this work fine: ```ruby a = Object.new # non-shareable prok = Ractor.current.instance_eval do Proc.new do eval('a') end end Ractor.make_shareable(prok) # this works, and it's okay because we get a different error when actually running the shareable proc inside a ractor that accesses outers through eval. ``` -- https://bugs.ruby-lang.org/

[ruby-core:111962] [Ruby master Feature#15778] Expose an API to pry-open the stack frames in Ruby
by gsamokovarov (Genadi Samokovarov) 22 Jan '23

22 Jan '23

Issue #15778 has been updated by gsamokovarov (Genadi Samokovarov). What if we settle for an API and implement and test it first in the `debug` gem? The `debug` gem does need/has similar functionality for post-mortem debugging. That way, gems like `web-console` can depend on the `debug` standard gem which I would expect more people to have, instead of using custom C extension. Other tooling can get debug APIs from the `debug` gem as well. It seems like a good place to start because we can test the APIs in real project and get real feedback. ---------------------------------------- Feature #15778: Expose an API to pry-open the stack frames in Ruby https://bugs.ruby-lang.org/issues/15778#change-101396 * Author: gsamokovarov (Genadi Samokovarov) * Status: Open * Priority: Normal * Assignee: ko1 (Koichi Sasada) ---------------------------------------- Hello, I'm the maintainer of the web-console (https://github.com/rails/web-console/) gem, where one of our features is to jump between the frames in which an error occurred. To accomplish this, I currently use the Debug Inspector CRuby API. I think we should expose this functionality in Rubyland, so tools like web-console don't need to resort to C code for this. This also makes it quite harder for me to support different implementations like JRuby or TruffleRuby as everyone is having a different way to create Ruby Binding objects that represent the frames. Here the API ideas: Add `Thread::Backtrace::Location#binding` method that can create a binding for a specific caller of the current frame. We can reuse the existing `Kernel.caller_locations` method to generate the array of `Thread::Backtrace::Location` objects. We can optionally have the `Kernel.caller_locations(debug: true)` argument if we cannot generate the bindings lazily on the VM that can instruct the VM to do the slower operation. - `Thread::Backtrace::Location#binding` returns `Binding|nil`. Nil result may mean that the current location is a C frame or a JITted/optimized frame and we cannot debug it. We can also expose the DebugInspector API directly, as done in the https://github.com/banister/debug_inspector gem, but for tools like web-console, we'd need to map the bindings with the backtrace, as we cannot generate Bindings for every frame (C frames) and this needs to be done in application code, so I think the `Thread::Backtrace::Location#binding` is the better API for Ruby-land. Such API can help us eventually write most of our debuggers in Ruby as right now we don't have a way to do Post-Mortem debugging without native code or even start our debuggers without monkey-patching `Binding`. I have presented this idea in a RubyKaigi's 2019 talk called "Writing Debuggers in Plain Ruby", you can check-out the slides for more context: http://kaigi-debuggers-in-ruby.herokuapp.com. -- https://bugs.ruby-lang.org/

[ruby-core:111945] [Ruby master Feature#15778] Expose an API to pry-open the stack frames in Ruby
by st0012 (Stan Lo) 20 Jan '23

20 Jan '23

Issue #15778 has been updated by st0012 (Stan Lo). Outside of error reporting, having this or similar API will also: - Allow IRB to display richer exception backtrace. This is helpful when used as `binding.irb`. - Allow IRB to implement a `bt` command that's similar to `debug`'s. - Whether to do this is another discussion and depends on other factors, but this API will enable that possibility. - Allow Rails to print backtrace with local variables in log or error pages. All of the above can be toggled by checking the gem's presence. ---------------------------------------- Feature #15778: Expose an API to pry-open the stack frames in Ruby https://bugs.ruby-lang.org/issues/15778#change-101378 * Author: gsamokovarov (Genadi Samokovarov) * Status: Open * Priority: Normal * Assignee: ko1 (Koichi Sasada) ---------------------------------------- Hello, I'm the maintainer of the web-console (https://github.com/rails/web-console/) gem, where one of our features is to jump between the frames in which an error occurred.

Issue #19112 has been updated by luke-gru (Luke Gruber). I was just looking into this bug and it's really strange, I initially thought it had to do with single ractor mode vs multi, but if we `sleep 100` inside the ractor everything behaves as it should, so it has to do with the ractor finishing. Once it finishes the tracepoints behave weirdly...
