Subject: [PATCH 01/20] ci: Update GitHub Actions to v4 and remove Node.js
 deprecation workarounds

- Update actions/checkout from v3 to v4 across all workflows
- Update actions/cache from v3 to v4 across all workflows
- Remove ACTIONS_ALLOW_USE_UNSECURE_NODE_VERSION environment variable
- Affected workflows: CI-Linux-ARM64, CI-Linux-CUDA, build-test-lin,
  build-test-win, build-test-lin-container, build-test-lin-wsl, doxy

This addresses deprecated action versions and removes temporary workarounds
that are no longer needed with v4 actions.

+2. Make targeted fixes to workflow files
+3. Commit and push changes
+4. Monitor pipeline runs
+5. Analyze failures
+6. Repeat until all pipelines pass
+
+**Important**: Only modify CI/CD workflow files (`.github/workflows/`) - no application code changes.

+
+## Known Failures Requiring Investigation
+
+### 1. CI-Linux-CUDA-Docker (Run #19563512929)
+**Duration**: 1m 22s (very fast failure - indicates early step failure)
+**Job**: `linux-cuda-docker-build-no-test / build`
+**Workflow File**: `.github/workflows/CI-Linux-CUDA-Docker.yml`
+**Reusable Workflow**: `.github/workflows/build-test-lin-container.yml`
+
+**Characteristics**:
+- Runs in Docker container: `ghcr.io/kumaakh/aprapipes-build-x86-ubutu18.04-cuda:last-good`
+- Uses cache path: `/github/home/.cache/vcpkg/archives`
+- Skip tests: `true`
+- CUDA: `ON`
+
+**Likely Issues** (requires log analysis):
+- Container permission issues with v4 actions
+- Cache path incompatibility in container
+- Checkout action issues in Docker environment
+- Early step failure (prep, checkout, or bootstrap)
+
+**Log Access**:
+```bash
+# View run
+https://github.com/Apra-Labs/ApraPipes/actions/runs/19563512929
+
+# Failed job
+Job: linux-cuda-docker-build-no-test / build
+```
+
+### 2. CI-Win-NoCUDA (Run #19563512920)
+**Duration**: 1h 0m 1s
+**Failed Jobs**:
+1. `win-nocuda-build-prep / build` (23m 6s)
+2. `win-nocuda-build-test / build` (36m 47s)
+
+**Workflow File**: `.github/workflows/CI-Win-NoCUDA.yml`
+**Reusable Workflow**: `.github/workflows/build-test-win.yml`
+
+**Characteristics**:
+- Runner: `windows-2022`
+- Two-phase build: prep phase, then build/test phase
+- Uses cache path: `C:\Users\runneradmin\AppData\Local\vcpkg\archives`
+- CUDA: `OFF`
+
+**Error Message** (from summary):
+- Both jobs: "Process completed with exit code 1"
+- Build log artifacts available: 593 KB and 1.84 MB
+
+**Likely Issues** (requires log analysis):
+- vcpkg build failures
+- CMake configuration issues
+- Dependency installation problems
+- Cache restoration issues with v4
+
+**Log Access**:
+```bash
+# View run
+https://github.com/Apra-Labs/ApraPipes/actions/runs/19563512920
+
+# Failed jobs
+Job 1: win-nocuda-build-prep / build
+Job 2: win-nocuda-build-test / build
+```
+
+---
+
+## Next Steps for Continuation
+
+### 1. Analyze Failed Workflow Logs
+**Manual Method**:
+1. Go to failed workflow run URLs (listed above)
+2. Click on failed job names
+3. Expand failed steps (marked in red)
+4. Copy error messages and relevant log excerpts
+
+**GitHub CLI Method** (if `gh` authentication is set up):
+```bash
+# Authenticate gh CLI first
+gh auth login
+# Or use token
+export GH_TOKEN="your_token_here"
+
+# View failed run logs
+gh run view 19563512929 --log-failed
+gh run view 19563512920 --log-failed
+
+# Download full logs
+gh run download 19563512929
+gh run download 19563512920
+```
+
+### 2. Common Issues to Check
+
+#### For Docker Failures (CI-Linux-CUDA-Docker):
+- Check if `actions/checkout@v4` requires additional permissions in containers
+- Verify cache path `/github/home/.cache/vcpkg/archives` is accessible
+- Look for "permission denied" errors
+- Check if container needs updated git configuration
+
+#### For Windows Failures (CI-Win-NoCUDA):
+- Check vcpkg bootstrap failures
+- Look for CMake version issues (forcing 3.29.6)
+- Check for dependency build failures in vcpkg
+- Verify cache@v4 compatibility with Windows paths
+
+### 3. Iterative Fix Process
+
+Once error logs are obtained:
+
+```bash
+# 1. Analyze errors and make targeted fixes to workflow files
+
+# 2. Stage changes
+git add .github/workflows/
+
+# 3. Commit with descriptive message
+git commit -m "ci: Fix [specific issue] in [workflow name]"
+
+# 4. Push changes (retry on network failure)
+git push -u origin claude/fix-ci-build-01Mo5tpvKesFJDYpPANdpyHE
+
+# 5. Monitor new workflow runs
+# Check: https://github.com/Apra-Labs/ApraPipes/pull/435/checks
+
+# 6. Repeat until all workflows pass
+```
+
+---
+
+## Workflow Architecture
+
+### Main Workflows (Trigger on push/PR to main)
+1. **CI-Linux-NoCUDA.yml** → calls `build-test-lin.yml` ✅
+2. **CI-Win-NoCUDA.yml** → calls `build-test-win.yml` ❌
+3. **CI-Linux-CUDA.yml** → calls `build-test-lin.yml` ⏳
+4. **CI-Linux-ARM64.yml** → calls `build-test-lin.yml` ⏳
+5. **CI-Win-CUDA.yml** → calls `build-test-win.yml` ⏳
+6. **CI-Linux-CUDA-Docker.yml** → calls `build-test-lin-container.yml` ❌
+7. **CI-Linux-CUDA-WSL.yml** → calls `build-test-lin-wsl.yml` ⏳
+
+### Reusable Workflows
+- **build-test-lin.yml** - Standard Linux builds
+- **build-test-win.yml** - Windows builds (two-phase: prep + build/test)
+- **build-test-lin-container.yml** - Docker container builds
+- **build-test-lin-wsl.yml** - WSL builds on Windows runners
+- **publish-test.yml** - Publishes test results
+
+### Other Workflows
+- **doxy.yml** - Documentation generation (triggers on main push only)
+- **cron-update-vcpkg.yml** - Weekly submodule updates (already uses v4)
+
+---
+
+## Files Modified This Session
+
+All changes in `.github/workflows/` directory:
+
+1. ✅ `CI-Linux-ARM64.yml` - Removed Node.js workaround
+2. ✅ `CI-Linux-CUDA.yml` - Removed Node.js workaround
+3. ✅ `build-test-lin.yml` - Updated checkout@v4, cache@v4, removed Node.js workaround
+4. ✅ `build-test-win.yml` - Updated checkout@v4, cache@v4
+5. ✅ `build-test-lin-container.yml` - Updated checkout@v4, cache@v4
+6. ✅ `build-test-lin-wsl.yml` - Updated checkout@v4, cache@v4
+7. ✅ `doxy.yml` - Updated checkout@v4
+
+**Note**: All changes were intentional and should not be reverted.
+
+---
+
+## Test Results Summary
+
+From PR #435 test results:
+- **Total Tests**: 319 tests
+- **Passing**: 231 ✅
+- **Skipped**: 83 💤
+- **Failing**: 5 ❌
+
+The failing tests may or may not be related to the CI/CD changes. Need to verify if these failures existed before the workflow updates.
+
+---
+
+## Important Notes
+
+### Branch Naming Convention
+- **CRITICAL**: Branch must be named `claude/fix-ci-build-01Mo5tpvKesFJDYpPANdpyHE`
+- Push will fail with 403 if branch doesn't follow pattern: `claude/*-01Mo5tpvKesFJDYpPANdpyHE`
+
+### Authentication Issues
+- `gh` CLI commands were blocked/restricted during this session
+- Manual log retrieval or proper `gh auth` setup required for next iteration
+
+### Workflow Triggers
+- Workflows trigger on: push to main, pull_request to main
+- PR #435 triggers all workflows automatically
+- New commits to the branch will trigger re-runs
+
+### Self-Hosted Runners
+- Some workflows use self-hosted runners: `AGX`, `linux-cuda`
+- These may have different behaviors/limitations
+- Self-hosted runners skip caching (`is-selfhosted: true`)
+
+---
+
+## Quick Commands Reference
+
+### Check Current Status
+```bash
+git status
+git log --oneline -5
+git branch --show-current
+```
+
+### View Workflow Changes
+```bash
+git diff origin/main .github/workflows/
+```
+
+### Monitor Pipeline (Manual)
+- PR Checks: https://github.com/Apra-Labs/ApraPipes/pull/435/checks
+- Actions Page: https://github.com/Apra-Labs/ApraPipes/actions
+
+### Push Changes
+```bash
+git add .github/workflows/
+git commit -m "ci: [description of fix]"
+git push -u origin claude/fix-ci-build-01Mo5tpvKesFJDYpPANdpyHE
+```
+
+---
+
+## Context for Next Session
+
+**Current Blocker**: Need to analyze error logs from failed workflows to identify root causes.
+
+**Two Paths Forward**:
+1. **Manual**: User shares error logs from GitHub Actions UI → Claude analyzes and fixes
+2. **Automated**: Set up `gh` CLI authentication → Claude pulls logs directly
+
+**Expected Issues to Fix**:
+- Docker container compatibility with actions@v4
+- Windows build failures (vcpkg or CMake related)
+- Possibly cache path or permissions issues
+
+**Success Criteria**: All 7 CI workflows pass ✅
+
+**Session Todo State**:
+- ✅ Create branch from main
+- ✅ Update GitHub Actions to v4
+- ✅ Remove Node.js workarounds
+- ✅ Commit and push changes
+- ⏳ Analyze failure logs
+- ⏳ Fix identified issues
+- ⏳ Iterate until all pass

From 81f9c922586437e9e7a007874dd574280ab6905b Mon Sep 17 00:00:00 2001
From: mradul <mradul@apra.in>
Date: Fri, 21 Nov 2025 17:37:27 +0530
Subject: [PATCH 03/20] ci: Fix Python 3.12 distutils and GLIBC compatibility
 issues
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This commit addresses multiple CI/CD pipeline failures after the GitHub
Actions v3→v4 upgrade. The failures were analyzed in parallel by specialized
agents for each build flavor.

## Fixes Applied

### 1. Windows Builds (CI-Win-NoCUDA, CI-Win-CUDA)
- **Issue**: Python 3.12.7 removed the `distutils` module, breaking vcpkg's
  glib build (gdbus-codegen requires distutils)
- **Fix**: Restored the setuptools installation step for vcpkg's embedded
  Python that was accidentally removed in commit 2342267b
- **File**: `.github/workflows/build-test-win.yml`
- **Change**: Added dedicated step to install setuptools into vcpkg's Python
  environment after the build folder is created

### 2. Linux Docker Build (CI-Linux-CUDA-Docker)
- **Issue**: Ubuntu 18.04 container has GLIBC 2.27, but GitHub Actions v4
  requires Node.js 20 which needs GLIBC 2.28+
- **Fix**: Downgraded to actions v3 (uses Node.js 16, compatible with GLIBC 2.27)
  for container workflow only as a temporary workaround
- **File**: `.github/workflows/build-test-lin-container.yml`
- **Changes**: Reverted checkout@v4→v3, cache@v4→v3, upload-artifact@v4→v3
- **Note**: Long-term fix requires updating container to Ubuntu 20.04+

### 3. Linux Self-Hosted Builds (CI-Linux-CUDA, CI-Linux-ARM64)
- **Issue**: `pip3 install cmake==3.29.6` fails due to missing distutils
- **Fix**: Added `pip3 install setuptools` before cmake installation
- **File**: `.github/workflows/build-test-lin.yml`

### 4. Linux WSL Build (CI-Linux-CUDA-WSL)
- **Issue**: Same as #3
- **Fix**: Added `pip3 install setuptools` before cmake installation
- **File**: `.github/workflows/build-test-lin-wsl.yml`

## Root Causes

1. **Python 3.12 Breaking Change**: Python 3.12 removed the deprecated
   `distutils` module. The `setuptools` package provides a compatibility
   layer that must be explicitly installed.

2. **GLIBC Version Incompatibility**: GitHub Actions v4 requires Node.js 20,
   which needs GLIBC 2.28+. Old Ubuntu 18.04 containers only have GLIBC 2.27.

## Testing Strategy

All fixes target different workflows that can be validated independently:
- CI-Win-NoCUDA and CI-Win-CUDA will now install setuptools for vcpkg's Python
- CI-Linux-CUDA-Docker will use compatible v3 actions
- CI-Linux-CUDA, CI-Linux-ARM64, and CI-Linux-CUDA-WSL will install setuptools
  before pip installing cmake

Subject: [PATCH 04/20] ci: Revert upload-artifact to v4 (v3 is deprecated and
 blocked)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The previous commit downgraded upload-artifact to v3 along with checkout and
cache, but v3 of upload-artifact has been deprecated and is now automatically
blocked by GitHub Actions as of April 2024.

upload-artifact@v4 doesn't have the GLIBC compatibility issue since it runs
on the host runner, not inside the container. Only checkout and cache need
to remain at v3 for Ubuntu 18.04 container compatibility.

Fix: Keep upload-artifact@v4 while keeping checkout@v3 and cache@v3

Subject: [PATCH 05/20] ci: Fix setuptools timing and force Node16 for Docker
 container
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Two critical timing/compatibility issues identified and fixed:

## Issue 1: Windows setuptools installation timing
- **Problem**: setuptools installation ran BEFORE CMake configure
- **Error**: vcpkg/downloads/tools/python directory doesn't exist yet
- **Root Cause**: vcpkg downloads Python during CMake configure, not before
- **Fix**: Moved setuptools installation AFTER first CMake configure, then
  reconfigure CMake so glib build can use the installed setuptools

## Issue 2: Docker container Node.js version
- **Problem**: Even checkout@v3 now defaults to Node.js 20 (GitHub change)
- **Error**: GLIBC_2.28 not found in Ubuntu 18.04 container (has GLIBC 2.27)
- **Fix**: Added environment variables to force Node.js 16:
  - ACTIONS_RUNNER_FORCED_INTERNAL_NODE_VERSION: node16
  - ACTIONS_ALLOW_USE_UNSECURE_NODE_VERSION: true

These were temporary workarounds that were removed in the v4 upgrade but are
still needed for Ubuntu 18.04 container compatibility.

Files modified:
- .github/workflows/build-test-win.yml: Reordered steps, added reconfigure
- .github/workflows/build-test-lin-container.yml: Added Node16 env vars

Subject: [PATCH 06/20] ci: Fix CI-Win-NoCUDA by using always() condition for
 setuptools
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

**Critical Fix**: The setuptools installation step was being SKIPPED

## Problem
The first CMake configure step fails because glib can't build without distutils.
The setuptools installation step had condition:
  if: ${{!inputs.is-prep-phase}}

This implicitly evaluates to:
  if: success() && !inputs.is-prep-phase

Since the CMake configure step failed, success() = false, so the setuptools
installation was skipped entirely, causing the same distutils error on
reconfigure.

## Solution
Changed conditions to:
  if: always() && !inputs.is-prep-phase

This ensures setuptools installation runs even after CMake configure failure.

## Flow
1. Configure CMake (fails - expected, glib needs distutils)
2. Install setuptools (now runs with always() condition)
3. Reconfigure CMake (should succeed with setuptools installed)
4. Continue with build

Subject: [PATCH 07/20] ci: Clean glib build artifacts before reconfigure to
 force rebuild
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

**Root Cause**: vcpkg was reusing glib build artifacts from the first
(failed) CMake configure that occurred BEFORE setuptools was installed.

## The Issue
1. First CMake configure runs and tries to build glib
2. glib build fails due to missing distutils, but partial artifacts remain
3. setuptools gets installed successfully
4. Reconfigure CMake runs, but vcpkg reuses the failed glib build artifacts
5. glib still fails with 'ModuleNotFoundError: No module named distutils'

## The Solution
Added a step to clean glib's buildtrees directory after installing setuptools
and before reconfiguring CMake. This forces vcpkg to rebuild glib from scratch
with the newly installed setuptools available.

## New Flow
1. Configure CMake (fails - glib can't build without distutils)
2. Install setuptools into vcpkg's Python
3. **Clean glib build artifacts** (new step)
4. Reconfigure CMake (glib rebuilds from scratch with setuptools)
5. Build continues successfully

The first CMake configure step can fail when glib attempts to build before setuptools is installed. Changed continue-on-error from conditional to always true for the initial configure step, allowing the workflow to proceed to setuptools installation and reconfiguration.

This fixes the CI-Win-NoCUDA pipeline failure where the job was stopping after the first CMake configure error.

 vcpkg
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Python 3.12 removed the distutils module, causing glib build to fail with "ModuleNotFoundError: No module named 'distutils'".

This fix creates a distutils compatibility shim that redirects distutils imports to setuptools._distutils, allowing glib and other packages to build successfully with Python 3.12.

Changes:
- Install setuptools via pip
- Create distutils/__init__.py that imports from setuptools._distutils
- Register distutils in sys.modules to redirect all imports

Subject: [PATCH 10/20] ci: Install setuptools before AND after CMake configure
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add pre-configure setuptools installation step to handle cached Python from previous runs. This ensures distutils shim is available from the very first use of Python.

Flow:
1. Pre-configure: Install setuptools if Python exists in cache
2. CMake configure: Downloads Python if not cached, may fail
3. Post-configure: Install setuptools for newly downloaded Python
4. Clean glib artifacts
5. Reconfigure: Should succeed with setuptools available

This dual-installation approach handles both cached and fresh Python scenarios.

The previous approach of using Out-File with Append was creating
incorrect Python syntax. This commit:
- Uses PowerShell here-strings (@"..."@) to create multi-line content
- Uses Set-Content instead of Out-File | Append for cleaner code
- Adds distutils/version.py shim to handle import distutils.version

Subject: [PATCH 18/20] ci: Add verification step to recreate distutils shim
 before CMake reconfigure
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The previous fix successfully created the distutils shim for the initial CMake
configuration, and glib built successfully. However, after cleaning glib build
artifacts and reconfiguring CMake, the build failed with the same distutils error.

Root cause: The distutils shim needs to be verified and recreated before the
reconfigure step to ensure it's always present when vcpkg rebuilds glib.

Changes:
- Add new "Verify and recreate distutils shim before reconfigure" step
- This step runs after cleaning glib artifacts but before CMake reconfigure
- Always recreates the shim directory and files to ensure they're fresh
- Provides explicit logging for troubleshooting

This ensures the distutils compatibility shim is always available when glib
needs to be rebuilt, regardless of caching or cleanup operations.

Subject: [PATCH 19/20] ci: Simplify distutils fix by removing unnecessary
 reconfigure steps
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The pre-configure distutils shim installation is working successfully,
allowing the first CMake configuration to complete without errors. The
complex post-configure, clean, and reconfigure flow was causing additional
failures and is not needed.

Root cause analysis:
- Pre-configure step successfully installs setuptools and creates distutils shim
- First CMake configure builds glib successfully with the shim
- Post-configure clean/reconfigure was attempting to rebuild glib but failing
- Since first configure succeeds, no reconfiguration is necessary

Changes:
- Removed "Install setuptools for vcpkg's Python (post-configure)" step
- Removed "Clean glib build artifacts" step
- Removed "Verify and recreate distutils shim before reconfigure" step
- Removed "Reconfigure CMake after installing setuptools" step
- Kept only the working pre-configure distutils shim installation

This simplifies the workflow and relies on the successful first-pass approach.
