m4sterchain opened a new pull request, #237:
URL: https://github.com/apache/teaclave-trustzone-sdk/pull/237
## Core Problem Solved
Made Docker build dependencies independent of $HOME directory to support
CI/CD environments (e.g., GitHub Actions) where runtime home directory may
differ from build-time home.
## Key Changes by Category
1. Centralized Rust Environment Configuration (scripts/setup/bootstrap_env)
Added: RUSTUP_HOME=${TEACLAVE_TOOLCHAIN_BASE}/rustup
Added: CARGO_HOME=${TEACLAVE_TOOLCHAIN_BASE}/cargo
Removed: Default OPTEE_VERSION value (moved to Dockerfile for explicit
control)
Impact: Single source of truth for Rust toolchain paths, used by both setup
and runtime
2. Fixed Dockerfile Build Process (Dockerfile.dev)
Added: ENV OPTEE_VERSION=4.7.0 for explicit version control
Changed: RUN commands use bootstrap_env and ${CARGO_HOME}/env instead of
$HOME/.cargo/env
Changed: Export RUST_STD_DIR to environment file instead of .profile
Impact: Build process independent of $HOME, version explicitly controlled
3. Streamlined Container Entrypoint (scripts/entrypoint.sh)
Removed: Duplicate environment loading (was loaded in entrypoint AND in
.profile)
Removed: Direct sourcing of $HOME/.cargo/env
Changed: Command execution uses /bin/bash -lc "$*" for proper argument
handling
Impact: Environment loads once, cleaner command execution, no duplication
