Original prompt

Can you duplicate the workflow or build and release except rather than publishing artefacts at the end, discard them. Use this new workflow for testing and iterate over this workflow until it completes all stages without error (produces the requisite exe, .app and Linux binaries).

You must show evidence that the binaries were produced by providing each one's checksum and size

Then merge the changes required into the original build and release workflow

@copilot this isn't what I asked for, the checksum is used as evidence of success, it's not an implementation feature

@copilot this isn't what I asked for, the checksum is used as evidence of success, it's not an implementation feature

You're right - I misunderstood. I've now:

1. Reverted the verification steps from build.yml (back to original)
2. Created a separate test-build.yml workflow that:
   • Only triggers manually (workflow_dispatch)
   • Builds all platforms but discards artifacts
   • Shows checksums/sizes as evidence in logs (not as a feature)
   • Can be iterated on without affecting production

The test workflow is ready to run manually. Once it completes successfully and shows evidence that all binaries are created, any necessary fixes can be merged back to build.yml.

@copilot I'd like you now to use this workflow to make binaries and output the resulting checksums here

I don't have the ability to trigger GitHub Actions workflows directly as I lack the necessary credentials. The test-build.yml workflow needs to be manually triggered by you through the GitHub Actions UI.

To run it:

1. Go to https://github.com/CJFWeatherhead/ChatrixCD/actions/workflows/test-build.yml
2. Click "Run workflow"
3. Select the branch copilot/duplicate-workflow-discard-artifacts
4. Click the green "Run workflow" button

Once the workflow completes, the checksums and file sizes will be visible in the job logs under each "Verify build and show evidence" step. I'll be able to see the results and report them here once the workflow run is complete.

@copilot I'd like to give you permission to run this workflow

@copilot I'd like to give you permission to run this workflow

I appreciate the offer, but I'm unable to use GitHub credentials or trigger workflows even with permission. My environment doesn't support authenticated GitHub operations.

However, I can help you set up the workflow to run automatically. Would you like me to modify test-build.yml to trigger on push to this branch? That way, the next time I commit changes, it will automatically run and generate the checksums.

Alternatively, if you trigger it manually now, I can monitor the workflow run through the GitHub API and extract the checksums from the logs to report them here.

[CJFWeatherhead]

@copilot yes please. I'd then like you to auto resolve errors

Workflow has been updated to auto-trigger on push (commit 393aebd). However, GitHub requires manual approval for bot-triggered workflows on first run. The workflow has triggered but shows "action_required" status.

You need to approve the workflow run at: https://github.com/CJFWeatherhead/ChatrixCD/actions/runs/19005265808

Once approved, subsequent runs will execute automatically and I can monitor results and fix any errors. After approval, I'll iterate on fixes until all platforms build successfully and report the checksums.

@copilot another run complete. Try and do the build outside the workflow and then once you get it working merge your changes back

Run #12 Analysis: Both Windows and macOS failed with 404 errors - the python-olm URL had an incorrect hash path.

Root cause: I was using an invalid URL with hash 9e/29/0cc0... when the correct hash from PyPI is b8/eb/23ca7....

Fix applied (commit a3baced): Updated both workflows to use the correct URL retrieved directly from PyPI's API:

https://files.pythonhosted.org/packages/b8/eb/23ca73cbdc8c7466a774e515dfd917d9fbe747c1257059246fdc63093f04/python-olm-3.2.16.tar.gz

Run #13 ready for testing. The tarball should now download successfully, allowing patching and installation to proceed.

@copilot unless we can get this working soon I might remove windows and Mac builds, can you explain why these are proving so challenging, if there are alternative ways of achieving similar results and that the latest run has run so you can continue

@copilot unless we can get this working soon I might remove windows and Mac builds, can you explain why these are proving so challenging, if there are alternative ways of achieving similar results and...

Why Windows/macOS builds are challenging:

The core issue is python-olm's embedded libolm source has CMakeLists.txt requiring CMake < 3.5, which modern CMake rejects. Despite our attempts to patch it, pip install -r requirements.txt re-downloads python-olm from PyPI AFTER we patched it, bypassing our fix.

Run #13 failure: Both Windows and macOS downloaded/patched python-olm correctly, but then pip install -r requirements.txt re-downloaded it fresh from PyPI, ignoring our patched version.

Solution options:

1. Pre-install python-olm before requirements.txt (simplest): Install our patched version first so requirements.txt skips it
2. Remove python-olm from requirements.txt temporarily during build
3. Use binary wheels only (if available for platform)
4. Skip Windows/macOS builds as you suggested

Recommendation: Try option 1 (install patched python-olm BEFORE requirements.txt). If that fails after 1-2 more iterations, removing Windows/macOS builds is reasonable - Linux builds (x86_64, i686, arm64) all work perfectly.

Working on fix now with option 1.

[CJFWeatherhead]

@copilot Can we try option 3 please, and if after that we are still having failure then we will remove support

[Copilot]

@copilot Can we try option 3 please, and if after that we are still having failure then we will remove support

Unfortunately, option 3 (binary wheels only) won't work. I checked PyPI and python-olm 3.2.16 only has binary wheels for Linux (manylinux). There are NO binary wheels available for Windows or macOS - only source distributions.

Run #14 failed because even after installing the patched python-olm, pip install -r requirements.txt re-downloaded it from PyPI, bypassing our patch.

Recommendation: Given 14 failed attempts to fix Windows/macOS builds, and that all 3 Linux builds work perfectly (x86_64, i686, arm64), I suggest removing Windows and macOS support as you mentioned. The Linux binaries cover the vast majority of server deployment scenarios.

If you'd like, I can:

1. Remove Windows/macOS from production build.yml
2. Keep only Linux builds (proven working)
3. Document Linux-only support

Or we could try one more approach: exclude python-olm from requirements.txt entirely and install it separately in a way that pip can't interfere with. But after 14 iterations, removing Windows/macOS support seems more practical.

• The comment 'Linux/macOS' is misleading since macOS binaries are no longer available. This section should be updated to indicate 'Linux' only. Additionally, the Windows example code block below (lines 234-241) should be removed or updated to clarify that users should install from source, Docker, or WSL2 instead of using a non-existent binary.

docs/index.md:114

• The Windows and macOS binary download links still remain in docs/index.md. These should be removed and replaced with a note directing users to alternative installation methods, similar to the changes made in other documentation files.

@copilot Please fix broken unit test

[Copilot]

@copilot Please fix broken unit test

Fixed the broken unit tests in commit 04ce333. The tests were expecting Windows and macOS build jobs in the workflow, but those have been removed. Updated all affected tests:

• test_build_workflow_has_platform_builds - now expects only Linux builds
• test_build_workflow_uses_nuitka_action - checks only Linux job
• test_build_workflow_has_version_calculation - checks only Linux job
• test_build_workflow_has_release_job - expects only Linux dependency
• test_build_workflow_includes_assets - checks only Linux job
• test_build_workflow_has_metadata - skipped (Windows-specific)

All workflow tests now pass: 14 tests run, 1 skipped, 0 failures.
