rightsize-modules 0.2.0

//! `sandbox-it` integration test for the SpringCloudConfig module. The interesting
//! claim here isn't just "it boots" — it's that `with_memory_limit(1024)` is required
//! on msb (measured evidence: timed out at 180s without the limit, ~19s with it,
//! because Paketo's memory calculator sizes this JVM image's fixed regions above
//! microsandbox's default microVM RAM).
//!
//! `SPRING_PROFILES_ACTIVE=native` is set here, test-side — not by the module —
//! because the image's default git-backed environment repository refuses to start
//! with no git URI configured (`BeanCreationException: ... You need to configure a
//! uri for the git repository`), unrelated to memory; the `native` profile switches
//! to a classpath/filesystem-backed repository that needs no external git remote.
//!
//! Run for real, once per backend:
//!
//! ```sh
//! RIGHTSIZE_BACKEND=docker cargo test -p rightsize-modules --features sandbox-it --test spring_cloud_config_it
//! RIGHTSIZE_BACKEND=microsandbox cargo test -p rightsize-modules --features sandbox-it --test spring_cloud_config_it
//! ```
