Description

When attempting to load the command-line-rest component of SEL on SBCL via Quicklisp, the compile process fails with a “Lock on package SERAPEUM violated” error. Specifically, invoking:

(ql:quickload :software-evolution-library/command-line-rest)

results in:

; caught ERROR:
;   READ error during COMPILE-FILE:
;
;     Lock on package SERAPEUM violated when interning POLICY> while in package
;     SOFTWARE-EVOLUTION-LIBRARY/SOFTWARE/DIRECTORY.

Steps to Reproduce

1. pull official sel image docker pull grammatech/sel
2. run container docker run -it grammatech/sel
3. exec sbcl sbcl --noinform
4. load quicklisp (load "~/quicklisp/setup.lisp")
5. load sel library (ql:quickload :software-evolution-library)
6. load command-line-rest component (ql:quickload :software-evolution-library/command-line-rest)

The SEL Docker image is a snapshot of the dependencies of the latest version of SEL, but doesn't include SEL itself. Running Quicklisp in it will pull down SEL from the latest Quicklisp dist, which right now is fairly out of date (October 2024). You'll need to manually clone the latest SEL inside the image:

git clone https://github.com/grammatech/sel ~/quicklisp/local-projects/sel

Cloning latest repository into local-projects directory worked.
Thanks for suporting.
