:IronRestart in ipython just makes the repl disappear but not restart

[drusmanbashir]

Hi I have noticed this bug when doing Deep learning on the GPU.
I press shortcut and the entire repl disappears. However the ipython process is not terminated. I can still see the GPU working.
In the past, i.e., 2 days ago, the repl would get fully terminated and a new repl would start in its place.

Thanks

Hi,

Thanks for the issue. I'll double-check. I think I have an idea of why is that.

For me, calling :IronRestart from another window causes the REPL window to disappear, but if I call it from the window of the repl, then it restarts as it should.

I don't know if it's the same issue or something else but with R (or radian) calling :IronRestart I get a similar behavior where the REPL window is closed and a new REPL starts on :IronRepl but the process for the previous R REPL is still visible in htop and the memory is not released.

Hi @jolars, are you 100% sure it kills the original process before starting a new one? If so, I will probably add a shortkey that combines IronFocus and IronRestart as a workaround

Hm, actually it is kind of weird. If I start a REPL in one window and call :IronRestart from another buffer (window), the window with the iron REPL is closed but there is still a buffer around that no longer responds to any commands. There is no new Iron REPL either.

For me, calling :IronRestart from another window causes the REPL window to disappear, but if I call it from the window of the repl, then it restarts as it should.

I can confirm that calling :IronRestart from inside the REPL does not indeed kill the existing process and free up resources. It just starts a new one. I think a workaround might be to create a shortcut that goes into the REPL, quits it, and then starts a new one. I will add the code snippet here for python when I have it.

I am working on a work-around on this issue. This keymapping does the following sequence:

1. Iron focus
2. quit python
3. Move to bottom window (my .py buffer)

keymap("n","",":IronFocusIquit() j", opts)

but if I add IronRepl at the end of this sequence, I am unable to start iron again. Currently, it does a partial job of quitting python which is not too bad either
