From 2531797383bb32089d87cf965f5c04228e9d3ba1 Mon Sep 17 00:00:00 2001 From: Michael Droettboom Date: Tue, 28 Jul 2026 19:35:10 -0400 Subject: [PATCH 01/27] CTK 13.4 prerelease integration (#2437) * run_cybind_cython_gen 13.4.0 ../ctk-next-public-main-staging-2026-07-15+1105 (NO MANUAL CHANGES) * run_cybind_native 13.4.0 ../ctk-next-public-main-staging-2026-07-15+1105 (NO MANUAL CHANGES) * git merge --squash ctk-next-public-main-2026-07-15+1105-merge && git rm -r -f qa/ (NO MANUAL CHANGES) * Regenerate cuda-core stubs after transfer preview (NO MANUAL CHANGES) * Support CUDA prerelease packages in fetch-ctk Resolve the public preview package set and extract it into the existing mini-toolkit layout while preserving stable redistributable behavior. * Add focused CUDA 13.4 prerelease wheel build Exercise one Linux x86_64 Python build through the existing wheel workflow without expanding the regular CI matrix. * Prepare for CTK 13.4 * Update tests to handle hidden reserved fields * Build CUDA 13.4 prerelease wheels in ordinary CI * Fix dangling pointer issues * Fix readonly and ownership bugs * CTK 13.4 fixes * Fix for CTK cache problem * Fix union types * Fix enum handling * Fix enums * Fix enum usage * Extend CUDA 13.4 prerelease CI to all four build platforms Windows preview toolkits ship as local installers rather than redistributable archives, so teach fetch-ctk to download and extract them and re-enable Windows wheel builds in the ordinary CI matrix, including a win-arm64 canary. * Assemble Windows CUDA 13.4 preview mini-CTK from installer components The local preview installer bundles per-component archives rather than a flat CUDAToolkit tree, so extract the needed component directories with 7-Zip and merge them into the layout fetch_ctk expects. * Streamline Windows preview CTK extraction in fetch_ctk Use a single 7-Zip pass, merge directly into the cache staging dir via a separate work directory, and drop prerelease-only unit tests that CI already exercises end to end. * Fix Windows preview mini-CTK lib layout for linker. Merge component libs into lib/x64 or lib/arm64 so cuda_bindings can find cudart_static.lib, and bump the prerelease cache key to drop stale flat-lib entries. * Drop layout-v2 cache key bump. Stale Windows prerelease caches were purged manually; the lib/x64 merge fix remains in fetch_ctk_redistrib.py. * Build Windows ARM64 wheels across supported Python versions Promote the successful canary to the full Python matrix and describe its CUDA 13-only wheel path as a single-major build. * Fix installation of cuda compute sanitizer * Fix for sanitizer-only install * Remove build smoke test --------- Co-authored-by: Ralf W.

The +primary improvements are: (1) raising exceptions rather than returning error +codes, (2) uses PEP8-compliant naming, and (3) more performance. This API is +still experimental and subject to change. + +Known issues +------------ + +* Updating from older versions (v12.6.2.post1 and below) via ``pip install -U cuda-python`` might not work. Please do a clean re-installation by uninstalling ``pip uninstall -y cuda-python`` followed by installing ``pip install cuda-python``. +* ``nvml.system_get_process_name`` on WSL can return incorrect values. To work around this, set the locale to "C" before calling ``nvml.device_get_compute_running_processes_v3`` (which sets the process names) and before calling ``nvml.system_get_process_name``. ``cuda_core`` does this automatically, but users of the raw NVML API will need to do this manually.

Dotted entries such as graph.Graph or checkpoint.Process are submodule namespaces and are excluded. Symbols documented in api_private.rst are accepted as documented so returned-helper docs do not fail the check. The tests skip when cuda.core.__all__ is not defined, so this lands independently of #2300 and activates once #2300 merges. Also adds the __all__-names-resolve guard suggested in the #2300 review.

Both are module-level singletons, and Stream_ensure_ctx / Stream_ensure_ctx_device stored the first context and device they observed on the object and never cleared them, so a process-wide object became permanently bound to one context. Replace the two helpers with resolvers that return the context and device through out-parameters and cache on the object only when the stream is not a default-stream token. Stream.context, .device, .resources, .record(), and __repr__ now follow the current context, a query no longer pins a context reference for the lifetime of the process, and the shared singletons are no longer written to from multiple threads. Object identity is preserved, so __eq__ and __hash__ keying off the handle are unaffected. Fixes #2485 * fix(cuda.core): harden default-stream context resolution for #2485 Skip sticky context reuse on default-stream tokens, document ambient context behavior on device/resources/record, and cover resources in the multi-GPU regression test. --------- Co-authored-by: Andy Jost * build: report internal build dependency provenance (#2509) * Fix nvbug6550424: Don't check NVML init behavior on CTK >= 13.4 (#2512) * cuda.core: add executable graph node updates (#2473) * Add executable graph attachment ownership Install a private CUDA user object per graph executable so later node updates can retain replacement resources safely. * Add executable graph node updates Expose ephemeral graph-node views that update complete executable parameters while retaining every replacement resource CUDA may still use. * test(core): cover executable graph node updates Exercise public mutators, rollback, source reclamation, independent ownership, whole updates, and in-flight cleanup end to end. * refactor(core): own exec graph creation behind one handle function Instantiation and whole-graph update each went through a prepare/commit pair. That exposed an opaque transaction type over the internal C++ interface and split the exec ownership contract between C++ and Cython, unlike every other resource handle, which a single create_* function owns end to end. Replace the pairs with create_graph_exec_handle and graph_exec_update. Each stages a fresh attachment accumulator on the source graph, makes the CUDA call with the GIL released, and adopts or publishes the result, so the staging transaction becomes a stack guard in the anonymous namespace instead of a header type. Cython keeps only what belongs to it: filling the instantiation params and decoding the failure reasons. The two driver entry points move into the C++ loader table with the calls. Convert the attachment append transaction to the unique_ptr plus rollback deleter pattern that node attachments already use, which retires the committed flag in favor of the same release-and-delete mechanism. Drop GraphExecBox::attachment_object, which nothing reads. * test(core): cover executable attachment accumulator lifetimes Three gaps remained around owners attached to an executable graph. Sequential updates to the same node must keep the superseded owner reachable, because CUDA cannot detach user objects from an executable; verified by breaking the append into a replace, which fails the new test on exactly that assertion. Closing an executable while a launch is in flight must not retire the accumulator, since the launch still writes through the buffer that an individual node update attached. A child-graph update attaches no owner of its own and relies on CUDA cloning the replacement graph's user object references into the executable. Assert that contract directly: the callback outlives the definition that supplied it and is released with the executable. * docs(core): describe the executable attachment accumulator CUDA accepts user objects on a CUgraph only, so an executable graph can never receive an owner after it exists. Document the consequence: one accumulator is retained on the source graph, propagated by instantiation or whole-graph update, and then released from the source so the executable becomes its only owner. Record why an owner is never removed once appended, and correct the two Scope entries that still described executable graphs as untracked. State the retention limit in the release notes as well. The API reference already documents it, but the note is what a reader sees when adopting the feature, and retention that looks unbounded deserves the warning there. * docs(core): focus executable attachment docs on cuda.core behavior Describe retention and complete-replacement rules without framing the notes around CUDA limitations, and shorten the executable attachment design section to problem, solution, and append-vs-replace limits. * docs(core): clarify Graph.__getitem__ for executable node updates Describe how callers use the view rather than how the binding retains handles or when CUDA validates the node association. * Address review feedback on executable graph attachments Clarify attachment ownership and deferred-cleanup docs, trim the invariants list to the cross-cutting rules, initialize instantiate params with Cython struct syntax, and simplify the executable update test helper. * test(core): restore explicit executable update kwargs The shared replacement fixture carries extra fields that are not update parameters, so spreading it as kwargs breaks memset and kernel cases. * Add check and agent guidance about uncapped mempools (#2514) * Add check and agent guidance about uncapped mempools * Address review: move mempool check to pre-commit, share POOL_SIZE Review feedback on #2514: - Move the uncapped-pool check out of the live test suite into a check-mempool-hygiene pre-commit hook.

Its tests move to ci/tools/tests, alongside the other check scripts'. - Add helpers/constants.py and route the eleven ad-hoc POOL_SIZE definitions through it. - Qualify "device memory" as installed/physical where the doc explains what an uncapped pool reserves. * build: report cuda-bindings provenance in PEP 517 builds (#2520) Resolve the CUDA path before importing cuda.bindings so the existing pathfinder import repairs PEP 517 namespace shadowing first.

That is the normal layout under manylinux (/opt/_internal/cpython-*/) and in GitHub Actions containers (/__w/), where `generate` then writes zero ABI files and exits 0 -- a green run with no coverage at all. `check`'s new-module scan had no filter, while `generate` skipped private modules. Since `generate` never wrote an .abi.json for them, `check` reported every private module as "New module added" on every run and set has_allowed_changes, so it could not print "No changes found" for a package shipping private submodules (cuda.bindings has _bindings/, _internal/, _lib/). Extract the predicate into iter_public_extension_modules() so both paths use it, and match only on the path relative to the package root. * Migrate cuda_pathfinder tests from os.path to pathlib (#2495) Part 4 of the series proposed in #2410. Filesystem predicates and path joining in the pathfinder tests now go through pathlib: os.path.isfile/isdir become Path.is_file()/is_dir(), os.path.basename becomes Path.name, os.path.join becomes Path joining, and the site-packages check uses Path.parts instead of splitting on os.path.sep. site_pkg_rel.replace("/", os.sep) is dropped in test_find_static_lib.py: Path already accepts forward slashes on Windows. Two files are left out on purpose. test_find_nvidia_binaries.py moves with part 3, whose signature changes it depends on. test_search_steps.py is being edited by #2489 (part 1), so converting it here would only create a conflict. Left on the stdlib modules: glob.glob in test_find_nvidia_headers.py, which expands an absolute pattern from the header catalog (Path.glob needs a base dir, and the wildcard is not pinned to the last component); os.pathsep in test_ctk_root_discovery.py, which builds PYTHONPATH, not a path; and os.sep in test_utils_env_vars.py, which builds a trailing separator on purpose. Signed-off-by: LeSingh1 * coverage: repair the Windows coverage wheels (#2508) Windows coverage has not collected a test since 2026-03-17. The job builds its wheels with a plain `pip wheel`, which never reads [tool.cibuildwheel], so the delvewheel repair every other Windows build performs never ran here. Those wheels import a bare "MSVCP140.dll" and resolve it against whatever the test machine has in System32, which on the coverage runner is 14.00.24215.1, built in 2015. _resource_handles.pyd is compiled by MSVC 14.44 and imports exactly _Mtx_lock and _Mtx_unlock from that DLL -- never _Mtx_init_in_situ, because std::mutex has had a constexpr constructor since VS 2022 17.10. The 2015 runtime still expects that initialisation and dereferences a null handle on the first lock, which _stream.pyx takes while cuda.core is still importing. It is the only extension module in either package that locks a mutex, which is why cuda.bindings and cuda.pathfinder have always passed on the same machine. Repairing the wheels vendors msvcp140 14.44 into cuda_core.libs and rewrites the import tables to match, so the process no longer depends on what the test machine carries. Verified on the coverage runner: 18 failed, 2929 passed, 918 skipped in 346s, against three to seven seconds of dying beforehand, and the first Windows coverage data since March. The same commit pins cuda-bindings to the wheel built one step earlier. PIP_PRE is set so pip will consider that wheel at all -- it carries a .devN version -- but it also admits PyPI's pre-releases, and cuda-bindings 13.4.0b1, published 2026-07-29, outranks the local build. Its cydriver.pxd comes from CTK 13.4 headers where CUmemLocation has a `localized` field, while cuda.core compiles against the 13.3.0 mini-CTK where it does not, so the build has been failing on `error C2039` ever since. Signed-off-by: Rui Luo * cuda.core: accept ProgramOptions(name=None) (#2517) * cuda.core: accept ProgramOptions(name=None) ProgramOptions.name is annotated str | None, but __post_init__ called .encode() on it unconditionally, so passing None raised AttributeError before any CUDA call was reached. Normalize None to the documented default, matching how arch is handled in the same method. The encoded value is identical to the existing default path, so the bytes passed to nvrtcCreateProgram are unchanged.

A resource configured with `location_type="host_numa"` or `"host_numa_current"` therefore reported `is_host_accessible is False` *and* `is_device_accessible is False` -- an impossible answer that propagates to `Buffer.is_host_accessible`, which forwards to the memory resource. Share a single `_HOST_LOCATION_TYPES` set between the constructor and the property so the two classifications cannot drift again. * cuda.core: validate ctypes host callback signatures against CUhostFn (#2525) * cuda.core: validate ctypes host callback signatures against CUhostFn Reject incompatible ctypes prototypes before CUDA sees them, document the required ABI, and note the stronger checking in the 1.2.0 release notes. * cuda.core: make ctypes flag lookups stubgen/mypy-friendly Use getattr for private ctypes calling-convention constants so the regenerated _host_callback.pyi type-checks cleanly. * cuda.core: check host callback prototypes via public ctypes attributes The previous check inspected ctypes' private _flags_ bits to identify the calling convention. That is wrong on Windows: CPython defines FUNCFLAG_STDCALL as 0, so a bitwise test can never match WINFUNCTYPE, and every win-64 test job rejected a valid callback. The 0x2 fallback used when _ctypes.FUNCFLAG_STDCALL is absent is FUNCFLAG_HRESULT, not stdcall. Drop the calling-convention check rather than repair the bit arithmetic. ctypes only honors stdcall when building a callback on 32-bit x86 Windows, which cuda.core does not support, and FUNCFLAG_PYTHONAPI is never consulted on the callback path, so CFUNCTYPE, WINFUNCTYPE, and PYFUNCTYPE all yield the same FFI_DEFAULT_ABI thunk. That leaves the declared result and argument types, which are reachable through the public restype/argtypes attributes. Reading those public attributes also lets a function pointer taken from a shared library be accepted once its restype and argtypes are declared, which the class-level lookup could never see. * chore: avoid some warnings when running cuda.core tests (#2515) * ci: constrain internal builds to exact local wheels (#2510) * ci: constrain internal builds to exact local wheels * ci: keep CI tool tests in nightly workflow * ci: generate local wheel constraints in workflows * fix(pathfinder): place Windows arm64 cudart test fixtures under bin/arm64 (#2528) * fix(pixi): restore conda test deps and relock after #2384 (#2532) #2384 inserted a pypi-dependencies header mid-table, moving conda test deps to PyPI without updating lockfiles.

Both publish code scanning results under the category /language:python, so keeping the local workflow would put two analyses on every commit that overwrite each other's alerts.

Grosse-Kunstleve * Use pathlib in cuda.pathfinder._static_libs (part 2 of #2410) (#2493) * Migrate _static_libs finders from os.path to pathlib Part 2 of the series proposed in #2410, following the same conversion style as part 1 (#2489). Path construction, joining, and filesystem predicates in find_static_lib.py and find_bitcode_lib.py now go through pathlib.Path instead of os.path string manipulation. Both modules keep importing os solely for os.environ.get("CONDA_PREFIX"). Compatibility is preserved: every entry point still accepts str, and every function that documents or returns str still returns str. Path is used strictly as the internal representation and converted back with str() at each return, so LocatedStaticLib.abs_path, LocatedBitcodeLib .abs_path, find_static_lib() and find_bitcode_lib() are unchanged in both type and value. No signature changes. Signed-off-by: LeSingh1 * Return Path from the _static_libs internals Follow-up to the review feedback on #2489: the str-compatibility constraint applies only to the public API. The try_* methods and _no_such_file_in_dir now work in Path throughout. str() is applied once, where abs_path is stored on the public LocatedStaticLib and LocatedBitcodeLib. The relative-path constants go from os.path.join(...) to forward-slash literals, matching how site_packages_dirs is already written in the same dicts; Path normalizes the separator on Windows. One behavior change: a CUDA_PATH or CONDA_PREFIX containing redundant separators ("//", "/.") now produces a normalized abs_path, because Path collapses them. Differential fuzzing against the pre-revision code (16k lookups over randomized trees, comparing located paths and full error text) shows no other difference, and none at all when those variables are free of redundant separators.

This addresses three of them, plus the guard that let one class of them through. Licensing metadata only; no logic changes. Copyright notices (15 files) Two different defects that happened to share a symptom: - 14 files under cuda_bindings/examples/ carried a non-standard notice ("Copyright 2021-2026 NVIDIA Corporation. All rights reserved.") with no (c), no SPDX-FileCopyrightText prefix, and the wrong entity casing. - toolshed/conda_create_for_pathfinder_testing.ps1 had the correct prefix and casing but was truncated before "& AFFILIATES. All rights reserved.". All now carry the canonical string. Years are preserved as found. Header guard (toolshed/check_spdx.py) COPYRIGHT_REGEX made "& AFFILIATES. All rights reserved." optional, so a bare "NVIDIA CORPORATION" satisfied pre-commit. The suffix is now required. (The 14 example files were passing for a different reason: .spdx-ignore excludes cuda_bindings/examples/ entirely. That exclusion is left alone here, but the files now conform, so it can be dropped in a follow-up if desired.) Tightening the regex surfaced two pre-existing files whose notice was split or truncated -- cuda_core/cuda/core/_include/layout.hpp and toolshed/build_static_bitcode_input.py. Both are corrected so the mandated sentence appears verbatim on one line. Third-party attribution (cuda_core/NOTICE) cuda/core/_include/aoti_shim.h is a vendored subset of PyTorch's AOT Inductor stable C ABI, BSD-3-Clause, carrying the upstream Facebook, Idiap, Deepmind, NEC and NYU copyright lines, but NOTICE listed only DLPack. A PyTorch entry is added with the full copyright block. The accompanying aoti_shim.def carries no copyright line of its own and is covered explicitly by that entry rather than given an NVIDIA header, since it declares the same upstream symbol names. The DLPack entry now also records where it is vendored. LICENSE files (all five) Every LICENSE ended at "END OF TERMS AND CONDITIONS", omitting the required "APPENDIX: How to apply the Apache License to your work" and its boilerplate. Appended to all five. The text is verified identical to the canonical Apache 2.0 appendix. Verified: 0 files with a non-conforming copyright string; check_spdx.py passes over all 868 in-scope tracked files with the tightened regex. Co-Authored-By: Claude Opus 5 (1M context) Signed-off-by: Rob Parolin * docs: document per-subproject license files in root README OSRB (NVBUG 4707569, comment #22) flagged the four sub-component LICENSE files as redundant with the root LICENSE and asked for either their removal or a root README Licensing section naming each subproject, its license and its license path. Each subproject builds an independent wheel and resolves its license file relative to its own root, so the copies are kept and documented instead of removed. Verified that the copies reach the built wheels: building cuda_pathfinder produces dist-info/licenses/LICENSE even though its pyproject.toml declares no explicit license-files (setuptools' default LICEN[CS]E* glob covers it), as is also the case for cuda_core. Co-Authored-By: Claude Opus 5 (1M context) --------- Signed-off-by: Rob Parolin Co-authored-by: Claude Opus 5 (1M context) * Use pathlib in toolshed and ci helper scripts (part 7 of #2410) (#2496) * Migrate toolshed and ci helper scripts from os.path to pathlib Part 7 of the series proposed in #2410. Path joining and filesystem predicates in the toolshed and ci/tools helper scripts now go through pathlib. glob.glob in dump_cutile_b64.py becomes Path.glob, with the mtime key reading Path.stat(). Kept on os.path, with a comment where it is not obvious: - os.path.abspath in build_static_bitcode_input.py, since sys.path wants a str and Path.absolute() does not normalize. - os.path.isfile in check_generated_file_seals.py. That guard exists to skip anything that is not a readable regular file, and Path.is_file() is not a drop-in: it propagates OSError for errnos outside pathlib's ignore list (EACCES, ENAMETOOLONG) where os.path.isfile returns False. - os.path.normpath in check_spdx.py, which already carries its own comment. The plan on #2410 also listed a root conftest.py; there is no such file. The three conftest.py files live under cuda_pathfinder, cuda_core and cuda_bindings, and none of them use os.path. Verified locally: ci/tools/tests/test_check_release_notes.py passes (42 tests), and check_spdx.py and check_generated_file_seals.py produce output identical to the pre-change scripts when run over every tracked .py file. Signed-off-by: LeSingh1 * Return Path from notes_path; use Path.is_file in seal checker Per review: treat these helper scripts as private, so notes_path can return Path and drop the str/Path round-trip at its call site. Accept the behavioral change from os.path.isfile to Path.is_file in check_generated_file_seals. * Review: thread Path through check_release_notes, drop remaining os.path Follow-up to mdboom's review. - repo_root is now a Path end to end: load_backport_branch, check_release_notes and validate_backport_decision take Path, and --repo-root parses with type=Path. That removes the Path(repo_root) re-wrap inside the functions and the 19 str(tmp_path) conversions the tests needed to call them. The five main() argv lists keep str(): those are command-line strings, which argparse then turns back into a Path. - build_static_bitcode_input: the last os.path use (os.path.abspath) becomes Path.resolve(); the os import is now unused and is dropped. --------- Signed-off-by: LeSingh1 Co-authored-by: Michael Droettboom * Fix operator precedence in test_cudart.supportsCudaAPI (#2554) def supportsCudaAPI(name): return name in dir(cuda) or dir(cudart) parses as `(name in dir(cuda)) or dir(cudart)`. `dir(cudart)` is a non-empty list for any module, so it is unconditionally truthy and the function returns a truthy value for every input, including names that exist nowhere. The left operand is dead too: `cuda` is cuda.bindings.driver and every name passed in is a cudaXxx runtime symbol. cudaGraphGetId, cudaGreenCtxCreate, cudaDeviceGetExecutionCtx and cudaGraphConditionalHandleCreate are all defined in runtime.pyx and appear nowhere in driver.pyx, so `name in dir(cuda)` is always False and the result is always the `dir(cudart)` list. Consequence: `not supportsCudaAPI(...)` is always False, so the API-presence half of all 17 skipif guards that use it (lines 1443-1954) never fires. On a build whose bindings genuinely lack the API, the test runs and dies with AttributeError instead of skipping; only the driver_version_less_than() half of each guard does any work. Adds test_supportsCudaAPI, pinning all three cases: a runtime-only name, a driver-only name, and a name that exists in neither. The last two fail before this change. * Catch up to current generator main (#2603) * Catch up to current cybind main * Bugfix for get_buffer_pointer * Fix the field-id enum name in the nvml test helper supports_nvlink (#2560) def supports_nvlink(device): fields = nvml.FieldValue(1) fields[0].field_id = nvml.FI.DEV_NVLINK_GET_STATE There is no `FI` attribute on cuda.bindings.nvml. The enum is `FieldId` (nvml.pyx:1229), with DEV_NVLINK_GET_STATE at nvml.pyx:1454, and the sibling test uses the correct spelling: test_nvlink.py:19 does `fields[0].field_id = nvml.FieldId.DEV_NVLINK_LINK_COUNT`. So the helper raises AttributeError on its first line of real work. Nobody has noticed because it has no callers -- a repo-wide grep for `supports_nvlink` finds only its own definition. Contrast util.supports_ecc, which is called from test_page_retirement.py. Adds tests/nvml/test_util.py, which stubs nvml.device_get_field_values so the helper can be exercised without an NVLink-capable device, and asserts both that it returns True and that it queried FieldId.DEV_NVLINK_GET_STATE. It fails with AttributeError before this change. * fix(core): don't crash `import cuda.core` on a non-integer opt-out value (#2535) `cuda/core/__init__.py` reads `CUDA_CORE_DONT_FIX_TAB_COMPLETION` with a bare `int(os.environ.get(..., "0"))` at import time. `int()` raises for any value that is not a base-10 integer, and `os.environ.get` returns the empty string (not the `"0"` default) when the variable is set but empty, so: export CUDA_CORE_DONT_FIX_TAB_COMPLETION= python -c "import cuda.core" ValueError: invalid literal for int() with base 10: '' Clearing a variable with `export VAR=` is the usual way to neutralize it in a shell profile, a Dockerfile, or a CI job spec, and `=true` / `=yes` are the obvious guesses for a boolean-looking opt-out. All of them make the whole package unimportable, which is a hard failure for a knob whose only purpose is to skip an optional `rlcompleter` patch. Parse the value leniently instead. Integer values keep their existing meaning (non-zero opts out, so `0` and `00` still install the patch), while a non-integer, non-empty value is honored as an opt-out rather than being silently ignored. Unset and empty/whitespace-only both mean "not set". Also document the variable, which was not listed on the environment variables page, and drop the stale "only installed in interactive mode" comment: the interactivity gate was intentionally removed in #2055 ("Always install the monkeypatch"), so the patch has been unconditional since then. The new parametrized test asserts the resulting behavior for eight values; four of them ("", " ", "true", "yes") fail on main because the subprocess exits non-zero with the ValueError above.

Replace Union[...] and Optional[...] with the | form the rest of the package already uses, e.g. `stream : Stream | None, optional` in _memoryview.pyx. Docstrings only, so the .pyi changes are the stubgen-pyx output for the edited .pyx files and no runtime behavior moves. In _module.pyx this also realigns the max_potential_block_size docstring with its signature, which already reads int | driver.CUoccupancyB2DSize. Two code-level spellings stay as they are: - LinkerHandleT in _linker.pyx is a runtime value, not an annotation. _program.pyx builds ProgramHandleT from it with `nvrtc.nvrtcProgram | int | LinkerHandleT`, and PEP 604 `|` on the forward-reference strings it holds raises TypeError. - The union_type literal in _process_define_macro is error-message text rather than a docstring. Sequence[...] and Iterable[...] elsewhere in cuda_core are collections.abc generics and are unaffected.

When that happens the diagnosis is wrong twice over: the reported type is registered, and `from None` suppresses the context so the traceback that would show the real failure is gone. >>> _add_cuda_native_handle_getter(Registered, getter_that_raises_keyerror) >>> get_cuda_native_handle(Registered()) TypeError: Unknown type: Move the getter call out of the try. The unregistered-type path is unchanged, which the existing test_get_handle_error still covers. * Resolve BENCH_DIR at call time in the benchmark runner's main() (#2563) discover_benchmarks() goes out of its way to avoid def-time binding, and says so: # Resolve the default inside the call so tests (and embedders) can # monkeypatch ``BENCH_DIR`` at the module level - Python binds default # args at def-time, so a literal default would ignore later patches. if bench_dir is None: bench_dir = BENCH_DIR main() then reintroduces exactly that binding: def main( *, bench_dir: Path = BENCH_DIR, default_output: Path = DEFAULT_OUTPUT, ... registry = discover_benchmarks(bench_dir=bench_dir, ...) Because main() always passes a non-None bench_dir down, the sentinel branch in discover_benchmarks() can never be taken on this path, and patching runner.main.BENCH_DIR - the documented mechanism - has no effect on main(). Same for DEFAULT_OUTPUT. run_pyperf.py calls main() with no arguments, so this is the production path. The existing tests patch BENCH_DIR and call discover_benchmarks() directly, which is why the gap is invisible today. Apply the same sentinel to both parameters. Explicit arguments keep working unchanged, so the embedder API is unaffected. Adds test_main_honors_a_monkeypatched_bench_dir, which patches BENCH_DIR to a tmp dir holding one bench_*.py and drives main() with --list. It fails before this change (main() lists the repo's real benchmarks instead). * cuda.core: Add copy_batch to cuda.core.utils (#2593) * cuda.core: Add copy_batch to cuda.core.utils * fallback for CUDA 12 and type annotations * be more precise about CUDA requirements * skip tests on Windows that require managed memory * rework some tests * Deduplicate _to_cumemlocation * add missing file * address review feedback * review feedback: don't assume NUMA capabilities * review feedback: clarify buffer requirements for async batched copies * review feedback: explicitly reject special default streams * review feedback: explicitly reject capturing streams * review feedback: drop warning about unsupported PREFER_OVERLAP_WITH_COMPUTE hint * review feedback: add missing descriptions for copy options values * review feedback: align CopyOptions validation with existing practice * review feedback: drop conditional imports for type checking * account for CUDA 12/13 driver differences * CUDA 12: drop rejection of unsupported copy options * simplify tests * fix(cuda.bindings): make cythonization warning-clean and enable -Werror (#2463) * fix(cuda.bindings): make cythonization warning-clean and enable -Werror Clear the Cython warnings that blocked matching cuda.core's warning_errors setting (#2450): drop ignored except clauses on Python-returning cudla cpdefs, declare LOAD_LIBRARY_SEARCH_SYSTEM32 as const in windll.pxd, and enable Cython Options.warning_errors in build_hooks.

But the marker regex only ever accepts two of the three: rb"^(?P#|\.\.) " `//` can never be captured, so `fullmatch` returns None for any sealed `.c` / `.cpp` / `.h` file and it is rejected as `MALFORMED generated-file seal` before the prefix comparison runs at all. The `b"//"` entries in `_COMMENT_CHARS` and the branch that would validate them are dead. Add `//` to the alternation, with a note tying it to `_COMMENT_CHARS` so the two do not drift again. This also adds the first tests for the script, under `toolshed/tests/`, and runs them alongside the existing `ci/tools/tests` in the nightly tooling job. The parametrized case is driven from `_COMMENT_CHARS` itself, so a future entry whose prefix the regex cannot match fails immediately instead of silently becoming dead code. * ci: add selective sdist build plumbing (#2465) * cuda.core: capture complete Buffer deallocation recipe at creation (#2526) * cuda.core: capture bound contexts for buffer deallocation streams Record a DeallocationStream at device-pointer creation so default-stream tokens pin the allocation context (and PTDS the allocating thread) instead of relying on ambient state at free time. * cuda.core: activate bound context during device-pointer teardown Make the deallocation stream's context current around free/unmap/MR cleanup so destruction no longer depends on ambient CUDA context, and wire cuCtxSetCurrent into the resource-handles driver table. * cuda.core: record from_handle deallocation streams at creation Add keyword-only stream= on Buffer/ManagedBuffer.from_handle when mr owns the pointer, bind it at construction, and cover teardown with no or foreign current context. * cuda.core: fail loudly on MemoryResource free errors Stop treating CUDA_ERROR_INVALID_CONTEXT as a successful pool free, and let explicit mr.deallocate() raise; destruction still contains errors in the callback.

Fixing the probe makes it run, and it passes. Its skip reason also blamed CTK 13.2, which is not the cause. libNVVM from CUDA 12.x rejects both spellings, so the option remains unavailable there; the release note says so. Closes #2570 Co-Authored-By: Claude Opus 5 (1M context) * fix(cuda.core): reject double-dashed NVVM options at the source Add a guard at the single exit point of _prepare_nvvm_options_impl that raises if any option is double-dashed. libNVVM accepts only single-dashed options, and every option on this path is generated from typed fields, so a double dash can only mean a bug in cuda.core rather than bad user input. Raising here names the offending option instead of leaving the user with libNVVM's opaque NVVM_ERROR_INVALID_OPTION. The guard is a separate cpdef helper so a test can exercise it directly; an inline check would be unreachable and therefore unverifiable. A second test sets every NVVM-supported field of ProgramOptions and asserts no emitted option is double-dashed, so the invariant covers options added later. Verified by mutation: restoring --numba-debug turns three tests red, and the compile test then fails with this guard's error rather than libNVVM's. The NVRTC path keeps --numba-debug, which it accepts; the guard is scoped to the NVVM emitter.

When set, the copy is submitted via `cuMemcpyWithAttributesAsync` if both cuda.bindings and the driver are CUDA 13.2+, the stream isn't `LEGACY_DEFAULT_STREAM`, and it isn't currently capturing; `PER_THREAD_DEFAULT_STREAM` is accepted like any other stream. `options=None` is unaffected and always uses the existing `cuMemcpyAsync` path. Passing `options` together with `LEGACY_DEFAULT_STREAM` or a capturing stream raises `TypeError`, matching `copy_batch`; a graph cannot represent these attributes, so `GraphNode.memcpy` (a plain, non-attributed copy) is the only way to get a copy into a graph today. On an older cuda.bindings/driver, `src_access_order` values of `STREAM` and `ANY` fall back to `cuMemcpyAsync` silently, since stream-ordered access already satisfies both. `DURING_API_CALL` promises all source reads complete before the call returns; a stream-ordered fallback can't honor that, so it raises `RuntimeError` instead of silently downgrading the guarantee, which could otherwise let a caller overwrite a source buffer before the real read happens. While aligning the two APIs, this also fixes two bugs in the existing `copy_batch`: it previously rejected `PER_THREAD_DEFAULT_STREAM` outright even though the driver accepts it, and its pre-CUDA-13 fallback loop silently ignored `DURING_API_CALL` despite a stale comment claiming that case was already rejected. Both now match the per-buffer behavior via a shared `_reject_unsupported_during_api_call` helper in `_copy_enums.py`. `cuMemcpyWithAttributesAsync` is absent from cuda.bindings older than 13.2, so it's routed through a small C++ function-pointer shim (`_cpp/resource_handles.{cpp,hpp}`) resolved at runtime, avoiding a hard Cython cimport that would break older-bindings builds. Tests: new `tests/memory/test_copy_single_options.py` covers data correctness across all `CopyOptions` fields, the `TypeError`/ `RuntimeError` rejection paths, default-stream-token and graph-capture behavior (including that `options=None` is unaffected by either), and `dst=None` auto-allocation. `test_copy_batch.py`/ `test_copy_batch_options.py` gain matching coverage for the `copy_batch` fixes, plus direct unit tests of the shared `DURING_API_CALL` guard. `test_memory.py` adds previously-missing size-mismatch rejection tests for `copy_to`/`copy_from`. Closes #2365. * cuda.core: reject register() on a non-IPC memory resource (#2569) * cuda.core: reject register() on a non-IPC memory resource MP_register read self._ipc_data._alloc_handle._uuid unconditionally. _ipc_data is None whenever IPC is not enabled, and Cython compiles the chained access without a none check, so the call terminated the process with a segmentation fault instead of raising. No exception reached the caller, so the crash could not be guarded with try. Check is_ipc_enabled first and raise RuntimeError, matching the wording the allocation_handle property already uses. The check runs before the registry insertion, so a rejected registration no longer leaves an entry behind.

It is not merely dead: `_translate_program_options` forwarded `numba_debug` from `ProgramOptions` into `LinkerOptions` on the `code_type="ptx"` path, so `Program(ptx, "ptx", ProgramOptions(numba_debug=True))` silently discarded an option the user explicitly set. Make the drop audible without breaking any caller: - `LinkerOptions.numba_debug` is deprecated. Setting it emits a `DeprecationWarning` from `__post_init__` and the value is still ignored. The field stays, so no constructor signature changes. - `_translate_program_options` no longer forwards it and emits a `UserWarning` saying it is ignored for `code_type="ptx"`. `UserWarning` rather than `DeprecationWarning` because `ProgramOptions.numba_debug` is not deprecated -- it is fully supported on NVVM and NVRTC and merely inapplicable to a linking backend. - The option builders are untouched; the linker needs no knowledge of `numba_debug` to ignore it. - `_LinkerBackend.validate` rejects nothing, and `numba_debug` stays out of `_LINKER_FIELD_GATES`: it cannot change PTX-path output, so it must not perturb the program-cache key. The warning gates differ on purpose. The linker field uses `is not None` -- the field itself is going away, so any explicit value earns the notice, including `False`. The PTX path uses truthiness, matching `_prepare_nvvm_options_impl`, because `False` asks for nothing. Removal of `LinkerOptions.numba_debug` is deferred to 2.0.0: the support policy confines breaking API changes to major-version boundaries and requires a deprecation notice at least one minor release ahead. Nothing in the repo tracks a scheduled removal -- the existing precedent (`Device.max_links`) only says "a future release" -- so a version-gated test fails the build once the version crosses 2.0. The NVVM and NVRTC paths are unchanged and still emit the option.

A producer that reports the allocation base in data and expresses a slice as byte_offset therefore produced a view pointing byte_offset bytes before the tensor, with nothing raised. The offset was also lost permanently on a round-trip, because the __dlpack__ re-export writes ptr back out as data with byte_offset = 0. The capsule-consuming importer in the same module already folds byte_offset in, so the two import paths disagreed about the same capsule. This makes view_as_dlpack match it.

Two independent caches are to blame, and neither tool notices the configuration changed: - Cython's up-to-date check hashes the .pyx and its cimport dependencies, but not compile_time_env. cuda.core feeds CUDA_CORE_BUILD_MAJOR through compile_time_env, so a cu13 -> cu12 switch silently reuses the cu13 generated C++. Reproduced on main: the cu12 build dies on 'CUdevWorkqueueConfigScope was not declared' in a build/cython/*.cpp generated under CUDA 13. - setuptools' build_ext compares source mtimes against the output .so. In an editable install that .so lives in the source tree under a name keyed by the Python ABI tag alone -- there is nowhere to record the CUDA major. So on a cu12 -> cu13 -> cu12 round trip the final build finds an older generated source next to a newer .so and skips the rebuild entirely. Both build backends now compute a build identity (CUDA major, plus the debug and coverage flags, which likewise change the generated C++ that neither tool tracks). Generated sources go to build/cython/, and build/.build-identity records the last completed build so setup.py can force build_ext when the configuration changes. Python version and platform stay out of the identity: setuptools already encodes them in its own build/lib.* and build/temp.* names. CUDA_PYTHON_COVERAGE keeps generating in-tree (build_dir=".") so it can still package the generated sources; it only contributes to the identity. Migration is self-healing. An existing unkeyed build/cython is orphaned and ignored; the first build after this change regenerates into a keyed directory and overwrites the in-tree extensions. Verified end to end with pixi on linux-64: cu13 -> cu12 -> cu13 for cuda_core. Before, the cu12 leg failed to compile; after, all three legs succeed, each major keeps its own build/cython/cu1X-debug directory, and the second cu13 extension is byte-identical to the first (md5 ae4090a4f66ab9cee67b5b2f64b43781), proving it was recompiled rather than left as the cu12 artifact. The new CI job covers cuda_core only. cuda_bindings cannot be source-built in its cu12 environment at all -- the 13.x sources reference CUDA 13-only symbols (CUatomicOperation, nvrtcBundledHeadersInfo, CUstreamCigCaptureParams), so even freshly generated cu12 sources fail against CUDA 12 headers. That is a pre-existing problem, unrelated to artifact staleness; the identical identity logic in cuda_bindings is covered by unit tests instead. Co-Authored-By: Claude Opus 5 (1M context) * build_hooks: match cuda_core's missing-cuda.h error message The two _determine_cuda_major_version implementations are annotated "keep in sync"; a missing cuda.h surfaced as a bare FileNotFoundError in cuda_bindings instead of the RuntimeError naming CUDA_PATH/CUDA_HOME. Co-Authored-By: Claude Opus 5 (1M context) * build: boil the CUDA-major fix down to essentials Cuts the change to the two mechanisms that are actually load-bearing for the cu12/cu13 problem, and drops everything that was speculative. Removed the debug and coverage identity axes. The stated justification for debug -- that gdb_debug changes the cythonize output -- is wrong: with gdb_debug=True the generated .c is byte-identical, and Cython only writes a side cython_debug/ directory. Keying by it produced a duplicate directory of identical sources and re-ran cythonize on every editable/wheel switch for no benefit. Coverage does change the generated C (linetrace), but toggling it is a separate defect from the one this PR is about. Removed the cuda_bindings half entirely. It has no compile_time_env, so its generated C is CUDA-major independent, and it cannot be source-built against CUDA 12 at all today -- the scenario the code guarded against is unreachable. That also drops a second _determine_cuda_major_version, a duplicated 50-line block, and a test file. What remains: cuda_core generates into build/cython/cu, and build/.build-cuda-major records the last completed build so setup.py forces build_ext when the major changes. The stamp is a bare major rather than a composite identity string, so the "no build ran" guard and its test are gone too. Re-verified cu13 -> cu12 -> cu13 on linux-64: all three legs build, both build/cython/cu12 and build/cython/cu13 exist, and the second cu13 extension is byte-identical to the first (md5 1c53ab83a7201d54576175c912d03e93). 18 unit tests pass; pre-commit clean.

Co-Authored-By: Claude Opus 5 (1M context) * build: address review feedback on CUDA-major-aware artifacts Use pathlib and anchor build artifacts to build_hooks.py rather than the working directory, since a project can be built from anywhere. This covers the cythonize build_dir as well as the stamp: anchoring only one would let the two caches resolve to different places when building from outside cuda_core/. Force a rebuild when the stamp is missing too. A missing stamp means the last build's CUDA major is unknown, and on a first build forcing costs nothing because there are no artifacts to reuse. Move _check_build_major() after the cuda.bindings import. It re-enters _get_cuda_path() and reads cuda.h, which must not happen before the pathfinder import has repaired PEP 517 namespace shadowing (#2520); the major is not needed until cythonize(). Restores test_cuda_path_is_resolved_before_importing_bindings. Also restores full-test's 90 minute timeout, unrelated to this change. Co-Authored-By: Claude Opus 5 (1M context) * test: cover the CUDA-major build wiring without a full build The cu13 -> cu12 -> cu13 CI job is the only thing exercising this fix, and it takes minutes. These check the same wiring in ~0.1s by replacing cythonize(), so nothing is generated or compiled: - generated sources for cu12 and cu13 land in different directories - that directory is anchored to build_hooks.py, so it agrees with the stamp regardless of the working directory - build_ext.finalize_options() picks up force_build_ext, and leaves force alone when it is clear Each was confirmed to fail when the corresponding fix is reverted. setup() is now guarded by __name__ == "__main__" so the command classes can be imported. setuptools always runs setup.py as a script, so builds are unaffected; verified with a clean rebuild. Note the sys.path handling in the cythonize helper: _build_cuda_core() permanently prepends cuda_bindings/ to sys.path, which makes setup.py's bare "import build_hooks" resolve to cuda_bindings' copy. The tests contain that mutation and pin the intended module.

Two threads launching distinct kernels could therefore insert into the global std::map concurrently, and race on the lazy ctypes type lookup. Do the work once, at import, while single-threaded: init_param_packer() fetches the ctypes types and builds the complete six-pair feeder table, leaving feed() a pure lookup over never-mutated state. utils.pxi calls it from its module body, which covers all three modules the .pxi is included into (driver, nvrtc, runtime) -- each compiles its own copy of the header's static state, so each needs its own init. The cached ctypes type pointers are now strong references rather than borrowed ones, and the ctypes module reference is a local released on both the success and the exception path instead of being leaked. This also removes a std::terminate hazard. fetch_ctypes() throws when `import ctypes` fails, and the old feed() was reachable from Cython as an implicitly-noexcept extern, so the throw aborted the process instead of raising. The throw now happens only inside init_param_packer(), declared `except +`. Cython's translation helper lets a pending Python error pass through, so the original ImportError propagates rather than being replaced by RuntimeError. feed() stays implicitly noexcept: after the restructure it genuinely cannot throw, so the hot path keeps no try/catch. The feeder table is unchanged in content -- the same six (target, source) type pairs the lazy path could ever build -- so behavior is identical, including the ctypes fallback taken whenever a lookup misses. In cuda.core, make mr_dealloc_cb std::atomic with release/acquire ordering. It is registered once at import from _buffer.pyx but read from shared_ptr deleters on arbitrary threads; the deleter now loads it once into a local rather than testing and calling the global as two separate reads.

That left target_t/source_t undeclared and `return;` statements in a function returning PyTypeObject*, so every module including the header (driver, nvrtc, runtime) failed to build. Restore fetch_ctypes_type, and move the intended range checks into the real populate_feeders(), where they take effect. On the error path the checked feeders now return 0 rather than -1. utils.pxi tests only `if size == 0` to decide whether to fall back, then does `data_idx += size`; a -1 would skip the fallback and rewind the pack buffer, so the next kernel argument would overwrite the last byte of the previous one. Returning 0 routes the value to the existing ctypes fallback instead. Any error raised by the conversion probe is cleared, because feed() is declared implicitly noexcept to Cython and must not leave an exception pending. This also fixes a pre-existing bug. feed() exists only to accelerate `ctype(value)`, so it must write what that would write. ctypes truncates out-of-range integers silently -- c_byte(300) is 44, c_int(2**40) is 0 -- but the old feeders called PyLong_AsLong and used the result regardless. Where `long` is 32 bits that overflows, leaving an OverflowError pending while still reporting a size, which surfaced as SystemError: ... returned a result with an exception set for c_int/c_byte/c_longlong arguments outside their slot. Declining those values makes the fast path and the fallback agree again. Verified under python3t.exe (3.15.0b3 free-threaded): the fast path is byte-identical to ctype(value) in all 391 (type, value) cells it claims; all 19 divergences from the previous feeders are cases the old code got wrong, none where the new code does; 3.2M concurrent feed() calls with the GIL off show no corruption; and driver/nvrtc/runtime all cythonize.

The warning's own text says "(Set CUDA_PYTHON_DISABLE_MAJOR_VERSION_WARNING=1 to suppress this warning.)", which reads as though 0 is the off value, and the other two boolean knobs in this repository disagree with it: cuda_bindings/.../_internal/runtime_linux.pyx:29 bool(int(os.getenv('CUDA_PYTHON_CUDA_PER_THREAD_DEFAULT_STREAM', default=0))) cuda_core/cuda/core/__init__.py:44 if int(os.environ.get("CUDA_CORE_DONT_FIX_TAB_COMPLETION", "0")): Both parse with int(), so `=0` is off for them. A user who sets all three to 0 gets the behaviour they asked for from two of them and the opposite from this one, silently losing a compatibility warning that exists to explain why their driver is too old. Parse the value with int() here too. Unset and empty still mean "not disabled". A value that is not an integer keeps the old set-means-disabled behaviour, so anyone currently relying on a spelling like `=true` does not start seeing the warning again -- `0` is the only input whose meaning changes. * Add an envvar_bool helper and use it for the version-check flag Replaces the flag-specific _warning_disabled with a shared envvar_bool, exported from cuda.bindings.utils. It recognises 1/true/yes/on and 0/false/no/off case-insensitively, falls back to C truthiness for other integers, and treats unset, empty, and whitespace-only as the caller's default. The helper lives in utils/_envvar.py rather than directly in utils/__init__.py because __init__ already imports _version_check, which needs the helper -- defining it in __init__ would make that import circular. It is re-exported so the public name is cuda.bindings.utils.envvar_bool. The parsing test moves to test_envvar.py and drives an arbitrary variable name instead of the version-check one. * fix(cuda.core): let cuda-gdb display source for JIT-compiled kernels (#2678) * test and a narrowish fix * marker * switch to pyelftools so we dont require a new ctk component * fix(cuda.core): repair two regressions in the NVRTC debug source path Redirecting the NVRTC program name at a temp .cu (#2679) left two problems. Quoted includes stopped resolving. NVRTC searches the directory of the name it is handed for #include "...", so moving that name into the temp dir moved the search with it, and merely enabling debug or lineinfo broke a compile that worked without it. The directory the name used to denote is now passed back as --include-path. It is added to the compile options only, never to ProgramOptions, so the program cache key is unchanged; the cwd was already an unkeyed input to these compiles before the redirect. Teardown deleted files it did not create. The name given to NVRTC doubled as the cleanup target, but that slot still holds the caller's options.name whenever the source was not redirected, so a name like "matmul.cu" matching a real file meant close() or collection deleted the caller's own source. The temp path is tracked separately now and is the only path unlinked. Removal on close() is left as it was, since gh-2422 asked for it and the tests added with #2679 assert it. * address reviews * cuda.core: accept dict for XyzOptions that are extension types (#2634) * cuda.core: accept dict for options in MemoryResource constructors * excempt some APIs cython annotation typing * pathfinder: also find ptxas in the nvidia/cu13/bin wheel layout (#2741) * fix(cuda.pathfinder): discover ptxas from NVIDIA wheels * test(cuda.pathfinder): add pytest-run-parallel dependency * docs(pathfinder): add 1.8.1 release notes * Fix nvbug6563848: Make tests properly skip on unsupported devices.

Move the class to its own module and resolve the primary context lazily. - LegacyPinnedMemoryResource.device_id returns -1 as documented; texture creation over a pinned buffer works again. - Device.set_current delegates a foreign-device context to its owning device instead of raising, so the save/restore idiom round-trips across devices. - Guard empty context handles once in invoke_in_context(_or_undo); warn when an undo is skipped because the target context is gone. - context_synchronize and context_get_stream_priority_range release the GIL like the other helpers. Rename array/mipmap box accessors to get_box. - Tests: query the driver (cuStreamGetCtx, cross-context cuEventRecord) instead of comparing cached metadata; add sync(), set_current round-trip, pinned texture, and synchronous-resource teardown tests; register device_x2 with the parallel-test plugin. - Move the release note to 1.3.0 and describe sync() as acting on the bound context. Co-Authored-By: Claude Fable 5.1 * cuda.core tests: fix driver-call plumbing in the bound-context helper handle_return() takes the whole result tuple, and cuCtxGetDevice() returns a CUdevice that never compares equal to an int; both made the cross-context event-record check raise instead of run (or skip) as intended. Co-Authored-By: Claude Fable 5.1 * cuda.core: regenerate stub with stubgen-pyx 0.2.22 Co-Authored-By: Claude Fable 5.1 * cuda.core: create stream-ordering events in the recorded stream's context The uniform empty-context guard added for review item 6 broke create_event_handle_noctx, which relied on an empty handle meaning "current context". That helper was itself a #2311-class bug: Stream.wait(stream) and the foreign-array/tensor import paths created their temporary ordering event in whatever context was current, and cuEventRecord rejects an event from a different context than the stream it is recorded on, so cross-device waits failed unless the right device happened to be current. Replace it with create_event_handle_for_stream, which resolves the stream's owning context via cuStreamGetCtx and creates the event there. Callers now check the returned handle and surface the real creation error. With that, every creation helper requires a context and no exception remains.

Memory the device cannot access has no stream ordering to preserve, so skip the binding when mr.is_device_accessible is False. Such buffers record no deallocation stream and never call the driver.

Running test_set_stats_level concurrently with test_stats_start_stop (which also calls set_stats_level(1)) can cause a race condition where get_stats_level() returns the value set by the other test, failing the assertion. All other cuFile stats tests (test_stats_start_stop, test_get_stats_l1/l2/l3) were already marked thread_unsafe; this commit fixes the oversight for test_set_stats_level. * Remove cupti dlls * Skip flaky test mentioned in #2790 * Fix version in release notes * Address agent feedback #3 - Medium: [arch_check.py:84](/wrk/forked/pr2788/cuda_python_test_helpers/cuda_python_test_helpers/arch_check.py:84) converts the raw NVML architecture integer to DeviceArch while handling an expected unsupported call. An unknown future architecture raises ValueError instead of skipping. Restore cont7’s try/except and UNKNOWN() fallback. * Address agent feedback #4: Update unsupported_before calls to use None instead of specific DeviceArch values. - Medium/low: [test_device.py:162](/wrk/forked/pr2788/cuda_bindings/tests/nvml/test_device.py:162) changed unsupported_before(device, None) to KEPLER. Mike’s pre-merge release branch and cont7 both use None; the adjacent getter does too. The current version propagates NotSupportedError on modern devices where the setter is unavailable. * test(cuda.core): serialize thread-unsafe IPC error tests (#2785) Signed-off-by: Rui Luo * Don't include pre-releases in the toctree * Revert test skip * test(cuda.core): serialize thread-unsafe IPC error tests (#2785) Signed-off-by: Rui Luo * Revert "cuda.core: refresh frozen CUresult explanation table for CUDA 13.3 (#2383)" This reverts commit 3df61150e66e697f6c9ba18a4c1798a77e3b3af1. * Validate that the ctk restored correctly * Add comment: Do not update it past CUDA Toolkit v13.1.1 * Remove erroneous validation --------- Signed-off-by: Rui Luo Signed-off-by: Aryan Signed-off-by: Bharat Raghunathan Signed-off-by: tirthpatel90 Signed-off-by: Omar Atie Signed-off-by: Jinfeng Signed-off-by: LeSingh1 Signed-off-by: Uday Arora Signed-off-by: Rob Parolin Signed-off-by: andrewwhitecdw Signed-off-by: Arpit Jain Signed-off-by: Vyron Vasileiadis Signed-off-by: Sebastian Berg Signed-off-by: dependabot[bot] Co-authored-by: Ralf Juengling Co-authored-by: Jinfeng Li Co-authored-by: Rui Luo Co-authored-by: Aryan Putta Co-authored-by: Bharat Raghunathan Co-authored-by: Andy Jost Co-authored-by: Sebastian Berg Co-authored-by: Michael Wang <13521008+isVoid@users.noreply.github.com> Co-authored-by: Michael Wang Co-authored-by: Ralf W.

The whole suite shares one process and one device, so these +reservations accumulate across tests. + +When a test needs its own pool, use the suite-wide cap from +`helpers/constants.py`: + +```python +from helpers.constants import POOL_SIZE + +mr = DeviceMemoryResource(dev, DeviceMemoryResourceOptions(max_size=POOL_SIZE)) +``` + +Use a larger value only if a test genuinely requires it, and prefer adding a +shared constant to `helpers/constants.py` over redefining one per module. + +### Passing no options is different from passing empty options + +`DeviceMemoryResource(dev)` with no options does **not** create a pool. It +wraps the device's existing default mempool (`_mempool_owned` is false) and +costs no additional address space. Passing *any* options object creates a new +owned pool, and a new pool without `max_size` is uncapped: + +```python +DeviceMemoryResource(dev) # wraps default pool, free +DeviceMemoryResource(dev, DeviceMemoryResourceOptions()) # NEW uncapped pool, expensive +DeviceMemoryResource(dev, {"ipc_enabled": True}) # NEW uncapped pool, expensive +``` + +Do not add `max_size` to a call that currently passes no options: that +converts a free default-pool wrapper into a new pool and makes things worse. + +### Managed pools are exempt + +`cuMemPoolCreate` requires `CUmemPoolProps.maxSize` to be zero for managed +pools, so `ManagedMemoryResourceOptions` has no `max_size` option. Managed +pools cannot be right-sized and are not checked. + +### Document exemptions + +When a call is deliberately exempt -- most often because it sits inside +`pytest.raises` and no pool is ever created -- annotate it: + +```python +with pytest.raises(RuntimeError, match="IPC is not available"): + # uncapped-pool-ok: raises before the pool is created + DeviceMemoryResource(mempool_device, DeviceMemoryResourceOptions(ipc_enabled=True)) +``` + +## Release resources at test boundaries + +The `init_cuda` fixture in `conftest.py` runs `gc.collect()` followed +by `cuCtxSynchronize()` before popping the context. Tests should not rely on +that as a substitute for cleaning up explicitly: prefer context managers for +resources whose lifetime fits a single scope, and keep pool lifetimes inside +the test that creates them. + +## Shared test support + +See also: https://docs.pytest.org/en/stable/reference/fixtures.html#conftest-py-sharing-fixtures-across-multiple-files + +Follow these rules when adding or moving shared test code: + +- Never import from a `conftest.py`. +- Put suite-wide fixtures and pytest hooks in `tests/conftest.py`. Put fixtures + needed only by one test subtree in that subtree's nearest `conftest.py`. +- Put a pytest hook in a nested `conftest.py` only if pytest supports that hook + there. If the hook receives suite-wide data, explicitly limit its effects to + the intended subtree. +- Code used only to implement fixtures or hooks may remain in the same + `conftest.py`. Put functions and constants imported by test modules in + `tests/helpers/` instead. +- Import helpers explicitly from the test root, for example: + `from helpers.memory import create_managed_memory_resource_or_skip`. +- Search `tests/helpers/` and `cuda_python_test_helpers/` for prior art + before adding a new helper; consolidate duplicates across + + packages into `cuda_python_test_helpers` (both `cuda_core` and + `cuda_bindings` test environments already depend on it). +- Fixtures in a nested `conftest.py` are available to tests in its directory + and descendants; fixtures from applicable parent `conftest.py` files remain + available. +- Do not add `__init__.py` solely because a test directory contains a + `conftest.py`. +- In directories without `__init__.py`, keep test-module basenames unique + within this test suite. + +## Skip only real setup failures + +`pytest.skip(reason)` records the test as SKIPPED with `reason` in the +report. A helper that wraps `yield` in `except Exception: pytest.skip(...)` +therefore records every test-body failure as a skip — a real regression, a +`TypeError`, an `AttributeError` all become "SKIPPED: <reason>" instead of +"FAILED", and the suite goes green regardless of whether the code under +test works. + +Catch only the specific exception that legitimately means "not available", +and only around the setup call — never around `yield`: + +```python +@contextlib.contextmanager +def _gl_context(): + try: + win, tex_id = _setup_gl_texture() # setup only + except (pyglet.NoSuchConfigException, GLContextError) as e: + pytest.skip(f"GL unavailable: {e}") + try: + yield tex_id # body exceptions propagate + finally: + _cleanup(win, tex_id) +``` + +The exception names in the example are illustrative — `GLContextError` +is not a real pyglet class. Match real pyglet exception names by type, or +use the shared `is_gl_context_unavailable` helper in +`cuda_python_test_helpers.graphics`. + +`GLException` is pyglet's generic GL-error class, raised after any GL call that reports an error +(`GL_INVALID_ENUM`, etc.). Do **not** include it in the "GL unavailable" set — it hides real bugs in GL allocation code as skips. + +Platform-specific "library not loadable" manifestations (genuine "GL unavailable"): + +- Linux without libGL/libEGL: `ImportError('Library "GL" not found.')` / `ImportError('Library "EGL" not found.')` from `pyglet/lib.py`. +- Windows without opengl32.dll: `FileNotFoundError` from `ctypes.windll.opengl32`; on Python 3.12+ `ctypes.LibraryLoader` re-raises `AttributeError("opengl32")`. + +When a CUDA call's error means "feature refused by this driver" (e.g. +`CUDA_ERROR_OPERATING_SYSTEM` for CUDA-GL interop on WSL), skip at the call +site with a narrow catch on the specific error, not inside the GL helper — +see `_register_gl_buffer` / `_register_gl_image` in `tests/test_graphics.py`. + +## `importorskip` is for optional dependencies only + +`pytest.importorskip("X")` is correct when `X` is genuinely optional +(platform-gated binding, parametrized "test each available module"). It is +dead code when `X` is a declared test or runtime dependency: the skip then +fires only when the environment is broken, which is the case you want to fail +loudly, not hide. Use a bare top-level `import` for declared deps. + +Before adding `importorskip`, check `cuda_core/pyproject.toml`'s `test` +and `test-cu*` groups and `cuda_core`'s `dependencies`. If the target is +listed, import it directly. + +## Capability probes must not swallow real bugs + +A probe function that answers "is feature X available?" by catching +`Exception` and returning `False` will report "not available" even when the +probed API failed for a real, unexpected reason — silently enabling a skip +that hides the bug. Catch only the exception that genuinely means "not +available", and split the checks so each catch is narrow: + +```python +def _is_nvfatbin_available(): + from cuda.bindings._internal.utils import FunctionNotFoundError + from cuda.pathfinder import DynamicLibNotFoundError + + try: + from cuda.bindings import nvfatbin + except ImportError: + return False + try: + nvfatbin.version() + except (DynamicLibNotFoundError, FunctionNotFoundError): + # libnvfatbin not loadable, or nvFatbinVersion symbol missing. + return False + return True +``` + +Catch only the exceptions that mean "not installed / not loadable". +A genuine API-status failure (e.g. `nvfatbin.nvFatbinError` from a +successfully loaded library) must propagate so a real bug is not hidden +as "unavailable". + +For a probe that calls a CUDA API returning a `CUresult`, let `handle_return` +raise on any non-success result and classify only a successful bitmask +lacking the documented bit as `False`; other failures propagate so a real driver bug is not hidden as "unsupported": + +```python +@functools.cache +def supports_ipc_mempool(device_id): + from cuda.bindings import driver + + handle_return(driver.cuInit(0)) + dev_id = int(getattr(device_id, "device_id", device_id)) + attr = driver.CUdevice_attribute.CU_DEVICE_ATTRIBUTE_MEMPOOL_SUPPORTED_HANDLE_TYPES + mask = handle_return(driver.cuDeviceGetAttribute(attr, dev_id)) + posix_fd = driver.CUmemAllocationHandleType.CU_MEM_HANDLE_TYPE_POSIX_FILE_DESCRIPTOR + return (int(mask) & int(posix_fd)) != 0 +``` + +Do not catch `ImportError` for a hard runtime dependency (e.g. +`cuda.bindings` for `cuda.core`) — that is a broken environment and should +surface at collection time. + +## Clean up partial setup on failure + +If a setup step allocates a resource (GL object, window, file handle) and a later +step fails, clean up the partial resource before re-raising so it does not +leak. Wrap the allocation in `try/except` and delete the generated object in +the `except` before re-raising: + +```python +def _allocate_gl_buffer(win, nbytes): + from pyglet.gl import gl as _gl + + buf_id = _gl.GLuint(0) + try: + _gl.glGenBuffers(1, ctypes.byref(buf_id)) + _gl.glBindBuffer(_gl.GL_ARRAY_BUFFER, buf_id.value) + _gl.glBufferData(_gl.GL_ARRAY_BUFFER, nbytes, None, _gl.GL_DYNAMIC_DRAW) + return buf_id + except Exception: + if buf_id.value: + with contextlib.suppress(Exception): + _gl.glDeleteBuffers(1, ctypes.byref(buf_id)) + raise +``` + +Initialize handles to `None` before the protected region so the `finally` +cleanup does not `NameError` when allocation raises before returning a handle. + +## Tests that touch CUDA must establish their own context + +The `init_cuda` fixture pops the CUDA context on teardown, so a test +that calls a CUDA API without `init_cuda` (or an explicit +`Device.set_current()`) inherits whatever context the previous test happened +to leave current on the thread — possibly none. With `pytest-randomly` that +makes the pass/fail outcome depend on test order, so it moves seed to seed and +looks like flakiness. Request `init_cuda` for any test that calls into the +driver, or set up and tear down a context yourself. + +## Assert on behavior, not implementation + +Pin on observable behavior the contract guarantees — return values, raised +exception types, public state transitions. Avoid asserting on internal +call counts, private helper invocation order, or error message substrings +that are not part of the contract. A refactor that preserves behavior but +changes internals should not break the test. diff --git a/cuda_core/tests/conftest.py b/cuda_core/tests/conftest.py index ca3782c67f2..a8678292422 100644 --- a/cuda_core/tests/conftest.py +++ b/cuda_core/tests/conftest.py @@ -2,15 +2,35 @@ # SPDX-License-Identifier: Apache-2.0 import functools +import gc +import importlib import multiprocessing import os import pathlib import sys -from contextlib import contextmanager -from importlib.metadata import PackageNotFoundError, distribution import pytest +# Keep in sync with cuda_bindings/tests/conftest.py. +try: + import cuda_python_test_helpers._pytest_plugin # noqa: F401 +except ImportError as e: + # Don't call .resolve(): resolving symlinks can make parents[2] point + # somewhere other than the monorepo root if a sub-directory is symlinked. + _test_helpers_root = pathlib.Path(__file__).parents[2] / "cuda_python_test_helpers" + if not _test_helpers_root.is_dir(): + raise RuntimeError(f"cuda-python-test-helpers not installed and not found at {_test_helpers_root}") from e + for _k in list(sys.modules): + if _k == "cuda_python_test_helpers" or _k.startswith("cuda_python_test_helpers."): + del sys.modules[_k] + sys.path.insert(0, str(_test_helpers_root)) + importlib.invalidate_caches() + +pytest_plugins = ["cuda_python_test_helpers._pytest_plugin"] + +from helpers.constants import POOL_SIZE +from helpers.memory import skip_if_pinned_memory_unsupported + import cuda.core from cuda.bindings import driver from cuda.core import ( @@ -23,73 +43,7 @@ PinnedMemoryResourceOptions, _device, ) -from cuda.core._utils.cuda_utils import CUDAError, handle_return -from cuda.pathfinder import get_cuda_path_or_home - -try: - from cuda.bindings._test_helpers.mempool import xfail_if_mempool_oom -except ModuleNotFoundError: - # Older cuda.bindings artifacts (for example 12.9.x backports) do not ship - # this helper yet.
