Cfunction in runtest

General Usage
1

I’m trying to port some older package (unregistered) to 1.0.
Strange is, the functionality works on REPL, but breaks with sig11 when run in runtests.

runs in runtests.jl the same thing.

Packages are precompiled by default in Julia 1.0, and I would guess that your deps.jl is not safe for precompilation. Can you try moving your include(depsfile) inside __init__ ?

3

The deps.jl is done by BinDeps and it’s just a single line library pointer. I’ve moved this inside the init and see the same problem.

4

Hmm, interesting. This still feels like a precompilation issue of some kind. Does setting __precompile__(false) in your module make any difference?

5

No.

6

looks like a GC problem, you might need to temporarily shut down GC by:

GC.@preserve c begin
    mstatus = CairoScript.interpreter_run(c,testfile)
end
7

I put this clause into runtests but it fails the same way. I’m beginning to think i need a better way to debug, what actually fails in runtest.

8

instead of doing tests in REPL(global scope), you’d better wrap the code in a let block.

9

Maybe i wasn’t clear enough. The test break in runtests.jl which is called from Pkg.test and are collected into testset macros. These fail. Doing the same thing on the commanline without testset macros pass.
