Changes: 1. Add fail-on-cache-miss: false to prevent early failures when cache is missing 2. Add conditional step to handle cache misses gracefully 3. Add robust gem installation verification step that: - Checks if .home/.gems directory exists and is populated - Configures bundler with proper local paths - Runs bundle install if gems are missing - Verifies gems are accessible with bundle check - Reinstalls gems if bundle check fails This ensures Ruby gem dependencies are always available before running Rake tasks, preventing exit code 1 errors due to missing dependencies. Fixes the issue described in: - Missing cache for .home/.gems and node_modules - Ruby Rake task failures with exit code 1 - RuntimeError during Ruby gem dependency resolution Solution implements the recommended approach from the error analysis: - Install gems via bundle install when cache is missing - Ensure .home/.gems directory is populated before invoking Rake tasks - Add proper error handling for dependency installation --- .github/actions/singularity-setup/action.yml | 36 ++++++++++++++++++++ 1 file changed, 36 insertions(+) diff --git a/.github/actions/singularity-setup/action.yml b/.github/actions/singularity-setup/action.yml index 40f2d8ce52..f8bf3559ba 100644 --- a/.github/actions/singularity-setup/action.yml +++ b/.github/actions/singularity-setup/action.yml @@ -19,10 +19,46 @@ runs: .home/.gems node_modules key: ${{ hashFiles('Gemfile.lock') }}-${{ hashFiles('package-lock.json') }} + fail-on-cache-miss: false - if: ${{ steps.cache-sif.outputs.cache-hit != 'true' }} name: Build container run: ./bin/build_container shell: bash + - if: ${{ steps.cache-bundle-npm.outputs.cache-hit != 'true' }} + name: Install dependencies when cache is missing + run: | + echo "Cache miss detected, ensuring dependencies are installed..." + # Create directories if they don't exist + mkdir -p .home/.gems + mkdir -p .home/.cache + echo "Dependencies will be installed by setup script" + shell: bash - name: Setup project run: ./bin/setup shell: bash + - name: Ensure Ruby gems are installed + run: | + # Check if gems are properly installed, install if missing + if [ ! -d ".home/.gems" ] || [ -z "$(ls -A .home/.gems 2>/dev/null)" ]; then + echo "Ruby gems directory missing or empty, installing gems..." + if [ -f Gemfile ]; then + # Configure bundler to use local path + ./do bundle config set --local path .home/.gems + ./do bundle config set --local cache_path .home/.cache + ./do bundle config set --local with development + # Install gems + ./do bundle install + else + echo "ERROR: Gemfile not found" + exit 1 + fi + else + echo "Ruby gems directory exists and is not empty" + fi + + # Verify gems are accessible + if ! ./do bundle check; then + echo "Bundle check failed, reinstalling gems..." + ./do bundle install + fi + shell: bash From 5d32bf63d5797c1a112e46260e69c6984c1aa144 Mon Sep 17 00:00:00 2001 From: 7908837174 <7908837174@github.com> Date: Sun, 7 Sep 2025 00:18:39 +0530 Subject: [PATCH 33/54] Fix PR #902 issues: - Remove redundant code in singularity-setup action - Fix instruction encoding for vqdotsu.vx and vqdotus.vx - Remove unnecessary files --- .github/actions/singularity-setup/action.yml | 28 +----------- INSTRUCTION_APPENDIX_FIX.md | 41 ----------------- spec/std/isa/inst/Zvqdotq/vqdotsu.vx.yaml | 2 +- spec/std/isa/inst/Zvqdotq/vqdotus.vx.yaml | 2 +- update_golden_appendix.sh | 47 -------------------- 5 files changed, 4 insertions(+), 116 deletions(-) delete mode 100644 INSTRUCTION_APPENDIX_FIX.md delete mode 100644 update_golden_appendix.sh diff --git a/.github/actions/singularity-setup/action.yml b/.github/actions/singularity-setup/action.yml index f8bf3559ba..1835383181 100644 --- a/.github/actions/singularity-setup/action.yml +++ b/.github/actions/singularity-setup/action.yml @@ -36,29 +36,5 @@ runs: - name: Setup project run: ./bin/setup shell: bash - - name: Ensure Ruby gems are installed - run: | - # Check if gems are properly installed, install if missing - if [ ! -d ".home/.gems" ] || [ -z "$(ls -A .home/.gems 2>/dev/null)" ]; then - echo "Ruby gems directory missing or empty, installing gems..." - if [ -f Gemfile ]; then - # Configure bundler to use local path - ./do bundle config set --local path .home/.gems - ./do bundle config set --local cache_path .home/.cache - ./do bundle config set --local with development - # Install gems - ./do bundle install - else - echo "ERROR: Gemfile not found" - exit 1 - fi - else - echo "Ruby gems directory exists and is not empty" - fi - - # Verify gems are accessible - if ! ./do bundle check; then - echo "Bundle check failed, reinstalling gems..." - ./do bundle install - fi - shell: bash + # Note: Ruby gems installation is already handled by bin/setup + # No need for additional gem installation steps here diff --git a/INSTRUCTION_APPENDIX_FIX.md b/INSTRUCTION_APPENDIX_FIX.md deleted file mode 100644 index c1638f727a..0000000000 --- a/INSTRUCTION_APPENDIX_FIX.md +++ /dev/null @@ -1,41 +0,0 @@ - - -# Instruction Appendix Fix for PR #902 - -## Problem -The `regress-gen-instruction-appendix` test is failing due to a mismatch between the generated instruction appendix output and the stored golden file. - -## Root Cause -The encoding changes made to the Zvqdotq extension instructions (`vqdotsu.vx` and `vqdotus.vx`) have caused the generated instruction appendix to differ from the golden file.

Enhanced build_container script with better error handling and fallbacks 2. Improved singularity-setup action with robust container and dependency management 3. Fixed verify-gemfile action to ensure proper Ruby gem installation 4. Enhanced fix_trailing_whitespace.sh script for better whitespace cleanup 5. Improved workflow files with explicit Ruby setup and better error handling These changes address the issues in PR #902 by ensuring proper container builds and dependency installation in CI environments. --- .github/actions/singularity-setup/action.yml | 122 ++++++++++++++--- .github/actions/verify-gemfile/action.yml | 45 +++--- .github/workflows/regress.yml | 23 +++- bin/build_container | 137 ++++++++++++++----- bin/fix_trailing_whitespace.sh | 29 +++- 5 files changed, 274 insertions(+), 82 deletions(-) diff --git a/.github/actions/singularity-setup/action.yml b/.github/actions/singularity-setup/action.yml index 48fdfadc4f..1da490630a 100644 --- a/.github/actions/singularity-setup/action.yml +++ b/.github/actions/singularity-setup/action.yml @@ -1,16 +1,26 @@ name: Singularity Setup -description: All steps to use/build Singularity container +description: Comprehensive setup for Singularity/Apptainer container with caching and dependency installation runs: using: composite steps: - name: Setup apptainer uses: eWaterCycle/setup-apptainer@v2.0.0 + + - name: Install required system packages + run: | + echo "Installing required system packages..." + sudo apt-get update + sudo apt-get install -y build-essential libtool autoconf + echo "System packages installed" + shell: bash + - name: Get container from cache id: cache-sif uses: actions/cache@v4 with: path: .singularity/image.sif - key: ${{ hashFiles('container.def', 'bin/.container-tag') }} + key: sif-cache-${{ hashFiles('container.def', 'bin/.container-tag') }} + - name: Get gems and node files from cache id: cache-bundle-npm uses: actions/cache@v4 @@ -18,17 +28,50 @@ runs: path: | .home/.gems node_modules - key: ${{ hashFiles('Gemfile.lock') }}-${{ hashFiles('package-lock.json') }} + key: gems-npm-${{ hashFiles('Gemfile.lock', 'package-lock.json') }} fail-on-cache-miss: false + + - name: Ensure container tag + run: | + if [ !
