Is there a `conda debug` equivalent? about boa

[wolfv]

Actually, I still haven't figured out what conda debug does. Can you describe it?

When a build fails, there is usually left-over environments in $CONDA_PREFIX/conda-bld that I usually use to debug my failed builds. The same is true for conda mambabuild.

Additionally with boa & the new recipe format, we've tried to make that more explicit -- and we also have a prototype for an interactive build-debugger in there. When you run with -i it will drop into a shell and you can create patches and other stuff from there.

You can try the boa-recipe format with boa convert myrecipe/meta.yaml > myrecipe/recipe.yaml and then build with boa build myrecipe.

conda debug has never worked perfectly for me with conda, but basically it just runs the conda build process normally up to the beginning of the stage matching a specified output-id fnmatch, and then stops with instructions for how to enter the build environment. It is supposed to dump a script into the folder that you can run to complete that stage, but that script has never materialised for me.

I think for me conda debug is mostly useful when I am running builds of multi-output packages, where it makes simpler keeping track of the right working directories of the several that are created during the build process.

It's a good point about the leftover working directories, so I will use them for the time being :). When I get some bandwidth I'll take a look at the new recipe format too!
