Every consuming product's CI checks out into a directory literally named `src` (see e.g. breadpad's checkout step), so basename(repo_root) resolved to "src" for every product in real CI runs — not the actual product name, which only looked right in local testing because that happened to run from a directory actually named after the product. In production this meant every product sharing the runner would have collided on the same image tag (bread-ci:src) and the same cargo-target cache volume, silently mixing compiled artifacts across unrelated repos. Caught before a second product (breadmon/breadclip/breadshot) started using this and made the collision real.

# Shared CI build script for bread-ecosystem GTK4/libadwaita apps.

# Builds (or reuses, via docker's own layer cache) the pinned Arch image
|
|
# from ci/Containerfile, then runs the given cargo command inside it
|
|
# against a product repo checkout.

#
|
|
# Usage: ci/build.sh <product-name> <product-repo-root> <cargo-command...>
|
|
# e.g. ci/build.sh breadpad /path/to/breadpad cargo build --release --locked
|
|
#
|
|
# <product-name> is used verbatim as the image tag and cache-volume name —
|
|
# it must be passed explicitly rather than derived from <product-repo-root>'s
|
|
# basename, because every product's CI checks out into a directory literally
|
|
# named `src`, which would otherwise collide across every product sharing
|
|
# this runner (same image tag, same cargo-target cache volume).
|
|
#
|
|
# If <product-repo-root>/ci/deps.txt exists (one pacman package per line,
|
|
# '#' comments and blank lines ignored), those packages are installed on
|
|
# top of the shared base image.
|
|
#
|
|
# Cargo's registry/git caches are shared across all products (same crates
|
|
# regardless of which app is building); CARGO_TARGET_DIR is cached
|
|
# per-product. Both persist in named docker volumes across runs.
