描述

I'm using VSCode to work with Julia notebooks. When I execute the following code in a fresh new notebook, I expect an error to be shown. Instead, the code yields nothing, not even an error.

using Plots
plot(1:50, 1:30)

However, if I execute the code snippet for 6 times (by clicking the little triangle at the left of the code cell), the following line is shown twice:

attempt to save state beyond implementation limit

If I repeat executing the code, three lines of "attempt to save state beyond implementation limit" keep showing.

When I execute the code snippet in the command line with GR backend, the normal error message is shown.

julia> plot(1:50, 1:30)
Error showing value of type Plots.Plot{Plots.GRBackend}:
ERROR: BoundsError: attempt to access 30-element UnitRange{Int64} at index [1:50]
Stacktrace:
  [1] throw_boundserror(A::UnitRange{Int64}, I::Tuple{UnitRange{Int64}})
...

Backends other than GR seems to have no problem, but I only tested UnicodePlots.

This issue seems to relate to the curious interactions among Julia, VSCode and .ipynb notebook.

I try to search the line of text in GitHub(https://github.com/search?q=%22attempt+to+save+state+beyond+implementation+limit%22&type=code) and see the "attempt to save state beyond implementation limit" line indeed shows up in lib/gr/gr.c.

研究方向
Investigate the interaction between Plots.jl, the GR backend, and the VSCode notebook environment. Look at the GR C library (gr.c) around the 'attempt to save state beyond implementation limit' error. Examine how Plots.jl handles error display in VSCode and why the error is suppressed initially. Consider the role of the notebook's execution context and potential race conditions or state issues.
