This Issue pertains to a Make workflow matter that only occurs on fresh git clones of the CASE repository, and is mitigable with a command repetition (which for some users is a 2-keystroke solution: up-arrow, return). This is not an ontology matter, so is planned to be processed without a vote, merged after the 2024-12-10 meeting.

Bug description

A parallel execution issue is present that sometimes arises when running make -j (a.k.a. make --jobs) in a fresh clone of the CASE repository, where a dependent file of the virtual environment wasn't created yet because of a missing dependency on submodule initialization. make without -j, which is how CASE's CI runs, has no problem because of the dependency ordering guaranteeing the dependent file (.../requirements.txt) would exist when the dependencies are addressed in order.

Steps to reproduce

This can be run in a fresh terminal, and is likely to note there is no rule to make dependencies/UCO/requirements.txt.

pushd `mktemp -d` ;
  git clone https://github.com/casework/CASE.git ;
  pushd CASE ;
    make -j 2 >/dev/null ;
  popd ;
popd

Mitigation

Running make -j again immediately after failure (or as a sequenced second command) seems to typically end up working, as the Git submodule initialization recipe runs to completion before make exits from the unsatisfied dependency. That recipe creates the file, satisfying the dependency from the first run.

Resolution

Have dependencies/UCO/requirements.txt depend on the submodule initialization flag file (.git_submodule_init.done.log).
