Build and test a wheel for Windows by alxmrs · Pull Request #118 · xqlsystems/einfold

🪭 Claude (einfold)

Adds a Windows x86_64 wheel to the release workflow, tested as the others are, on Python 3.10, 3.13 and 3.15. Stacked on #117, which changes the same workflow.

Decisions to review

Windows was left out of 0.1.0rc1 because the tests used Unix's resource module. Add einfold for Python: an extension for datafusion-python sessions #75 since moved that into a Linux-only child script, and the Linux-only stack workaround is a no-op elsewhere, so the tests may run unchanged. This pull request changes the release workflow, so the workflow runs on it, and its Windows jobs will show whether they do.
Deep plans: Windows gives a main thread a 1 MB stack by default, against Linux's 8 MB, so the README's limit on deep plans is tighter there. The README says so. If the deep-plan test fails on Windows, I'll skip it there with that reason, as on macOS.

How it is tested

actionlint passes. This pull request's run of the release workflow is the test.

Walkthrough

The release workflow adds weekly runs, narrows pull-request path filters, and builds and tests Windows x86_64 wheels. The release instructions list Windows, and the deep-plan limitation notes describe Windows’ default main-thread stack size and join-count caveat.

Changes: Windows release support

Layer / File(s)	Summary
Release workflow triggers `.github/workflows/release-python.yml`	The workflow adds a Monday schedule and narrows pull-request path filters to the workflow and Python packaging files.
Windows wheel build, test, and platform notes `.github/workflows/release-python.yml`, `CONTRIBUTING.md`, `python/README.md`	The workflow adds Windows x86_64 to the wheel build and test matrices. The release instructions list Windows. The deep-plan notes describe Windows’ 1 MB default main-thread stack and state that fewer joins may cause overflow on Windows.

Merge Risk: Moderate · up to f13b5

Adding Windows to the release test matrix currently fails the deep-plan test on Python 3.10 with a stack overflow, which blocks the release workflow's publish step. Fix the overflow or add a narrow Windows guard, and re-check the README's Windows stack-size wording, before merging.

Security architecture risk: Minimal · up to f13b5

The new Windows wheels must pass the release test matrix before publication. Weekly and pull-request runs cannot publish, and publication permissions remain restricted to matching release-tag pushes. No material security risk introduced or worsened by this change was identified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

inferred — The release supply chain gains a Windows runner and a Windows artifact that can reach the existing PyPI project and GitHub release. This expands the set of build outputs trusted by publication, but the workflow does not add another publication destination or grant the new platform jobs publication permissions.

Trust Boundaries and Controls

observed — Pull-request code can execute in validation jobs, but those executions cannot satisfy the publish job's push-and-tag predicate. Scheduled and manual runs are excluded by the same predicate. For release-tag pushes, tag/version equality and successful build and test dependencies remain required before elevated publication runs. These controls are unchanged from the supplied base.

 ### Limits

- **Very deep plans.** A session hands einfold each plan through DataFusion's FFI, which decodes it recursively on the thread that asks. On Linux, einfold raises the main thread's stack limit, so plans of about 2,000 joins work there. On another thread, or on macOS, a plan of a few hundred joins can overflow the thread's stack, and the process exits rather than raising an error.

To specify a different default stack reservation size for all threads and fibers, use the STACKSIZE statement in the module definition (.def) file. The operating system rounds up the specified size to the nearest multiple of the system's allocation granularity (typically 64 KB). To retrieve the allocation granularity of the current system, use the GetSystemInfo function. To change the initially committed stack space, use the dwStackSize parameter of the CreateThread, CreateRemoteThread, or CreateFiber function. This value is rounded up to the nearest page.

Distinguish the Windows linker default from CPython's stack reserve.

The supported Windows workflow uses CPython 3.13 and 3.15 executables that reserve 2,000,000 bytes for the main thread. The current 1 MB wording and “fewer on Windows” comparison are misleading for those executables.

Fix the Windows Python 3.10 deep-plan test failure.

Adding Windows to the test matrix runs test_plans_deep_queries in the main process. The job reports a stack overflow at on.sql(sql).to_pydict() and exits with code 127. The existing Linux-only guards do not cover this test. Handle the Windows case before publishing. Add a narrow platform guard only if the affected plan exceeds Windows stack capacity; otherwise fix the overflow.

einfold, a query optimizer for DataFusion that runs tensor computations in SQL with array algorithms, released its first candidate. The demos gain an einfold host: xarray-sql's Context with einfold as its query planner. Demo 1 now checks that einfold runs both spellings of attention, and the Nadaraya-Watson control, as one fused pipeline: FlashAttention's tiled plan, found from the SQL. The README gives einfold's numbers. einfold has no Windows wheel yet (xqlsystems/einfold#118), so the dev group skips it on Windows rather than build it from source. ddxdb 0.4.6 differentiates through UNION ALL and computes a step read once inside its reader, which takes the GPT's program from 77 steps to 64.

🪭 Claude (einfold) Users install einfold for Python with a plain `pip install "einfold[datafusion]"`, without `--pre`, once this merges and `python-v0.1.0` is tagged on it. [xarray-sql](https://github.com/xqlsystems/xarray-sql), an XQL Systems project that queries Xarray datasets with SQL, accepted 0.1.0rc2, so this sets the version in `python/pyproject.toml` from `0.1.0rc2` to `0.1.0`. The code is the same as rc2's, plus the fixes since then: #122 (a test for #66), #124 (a test's thread counts) and #125 (the Rust crates' packaging). ## Decisions to review - **The READMEs drop `--pre`, and keep `--upgrade`, so the command replaces an installed release candidate** ([`README.md`](README.md), [`python/README.md`](python/README.md)). The top README now says 0.1 is released, from Python and from Rust, since the crates are on crates.io as 0.1.0. - **The classifier stays `Development Status :: 3 - Alpha`.** einfold detects a limited set of shapes, and Windows isn't supported yet (#118). 🤖 Generated with [Claude Code](https://claude.com/claude-code) https://claude.ai/code/session_01M96xSez6PZwTmfaGh2eJgS --------- Co-authored-by: Claude Opus 5.5 <[email protected]>
