Fatal error after include-workspace-include

General Usage
1

I get a rather weird reproducible error that crashes Julia in REPL and freezes it in Jupyter. The error happens whenever I use include followed by workspace then include again. I am using v0.50.

The code I run is:

include("test_prep.jl")
#Some tests and debugging
workspace()
include("test_prep.jl")

Here is the content of test_prep.jl:

include("VTKDataTypes\\src\\VTKDataTypes.jl")
include("VTKDataIO\\src\\VTKDataIO.jl")

using VTKDataTypes
using VTKDataIO

Here is the content of VTKDataTypes.jl:


module VTKDataTypes

using WriteVTK

include("vtkcelltypes.jl")
include("types.jl")
include("utils.jl")
include("validation.jl")
include("typeconversion.jl")

export AbstractVTKData, AbstractStaticVTKData, AbstractTimeSeriesVTKData
export AbstractVTKSimpleData, AbstractVTKMultiblockData
export AbstractVTKUnstructuredData, AbstractVTKStructuredData, AbstractVTKRectilinearData
export VTKUnstructuredData, VTKStructuredData, VTKRectilinearData, VTKUniformRectilinear, VTKImageData
export VTK_CELL_TYPE, POINT_CELLS, LINE_CELLS, FACE_CELLS, VOLUME_CELLS
export LINEAR_CELLS, QUADRATIC_CELLS, CUBIC_CELLS, HIGHER_ORDER_CELLS, HIGHER_ORDER_PARAMETRIC_CELLS, SPECIAL_CELLS
export promote_rule, size, length, getindex, endof, start, next, done
export same_geometry, ==, same_ordered_geometry, same_geometry_shape, same_data_shape, coherent
export extents, dim, num_of_points, num_of_cells, num_of_point_vars, num_of_cell_vars
export cell_type, cell_connectivity, has_var, var_dim, vtk_cell_type_name, is_homogeneous, filter_cells!
export keep_volume_cells_only!, keep_face_cells_only!, get_cell_ids, get_lowest_index, get_highest_index
export is_valid_cell, add_new_cell, remove_cell!, add_point_id_offset!, append!, append
export num_of_blocks, insert_new_block!, remove_block!, timespan, num_of_timesteps, insert_timed_data!
export remove_timed_data!, remove_timed_data!, is_valid, convert

end

Here is the content of VTKDataIO.jl:

module VTKDataIO

using VTKDataTypes
using WriteVTK
using PyCall
@pyimport paraview.simple as pv
@pyimport paraview.servermanager as ps
@pyimport paraview.numpy_support as pnp

include("paraviewreaders.jl")
include("vtkwriters.jl")

export read_vtk, write_to_file

end

Finally here is the longest bit, the error. Anyone knows what I am doing wrong, if anything at all?

There was a recent thread that, as far as I remember, basically said “don’t use workspace”.

Would the following work instead? Basically a gutted-out workspace that does not save the last module.

function cleanworkspace()
    lastbase = Core.Main.Base
    ccall(:jl_new_main_module, Any, ())
    newmain = Core.Main
    ccall(:jl_add_standard_imports, Void, (Any,), newmain)
    eval(newmain, Expr(:toplevel, :(const Base = $(Expr(:quote, lastbase)))))
    empty!(Base.package_locks)
    nothing
end

EDIT the original was overenthusiastic and axed Base.

FWIW, this still breaks if you are using PyPlot (which has always been a problem with workspace()).

I get around this by putting most of my code into modules and not introducing the modules into the REPL scope (ie don’t use using at top level scope). Basically what is described here: https://docs.julialang.org/en/stable/manual/workflow-tips/

If I really need the REPL for debugging purposes I will load the modules and then restart julia when I’m done with the debugging/editing and want to test my code again.

Another option if you want to use code in the REPL without using MyModule is to qualify the methods, ie: MyModule.MyMethod()

When I drop workspace, and I change a function definition, I get this warning WARNING: using VTKDataIO.read_vtk in module Main conflicts with an existing identifier. and it keeps on using the old function definition.

Surprisingly, when I qualify the function call with the module name, it uses the new definition.

Edited to add: Or I guess not so suprisingly, but it seems that simply redefining a module and calling using again does not redefine all the functions already in the main scope, but the functions in the module’s scope are actually the new ones, which is potentially a bug.

EDA: But then I guess this non-functionality was…added so that any sub-module does not get defined multiple times if used by multiple modules by running using on the final version of each of those modules in the actual program.

Some / much of this has changed in Julia 0.6.

Thanks! It works. I added it to my juliarc file.
Devs, could we get this permanently?

See updated version, which now also loads ~/.juliarc.jl.
