and add FA102 for missing from __future__ import annotations. Prevent issues like #959.

Or use UP035 (with FA102) only if this is too wide.

This should be sufficient to keep py38 compatibility for a long time.

Estimated code review effort

🎯 4 (Complex) | ⏱️ ~75 minutes

The changes are largely homogeneous—systematic application of the same type-modernization pattern across 80+ files. However, the scale, combined with a handful of behavioral modifications scattered throughout (runtime gating in phase.py, validation changes in target.py, logic adjustments in builtin.py), demands careful verification that no unintended side effects were introduced. The code is repetitive but requires spot-checking for correctness.

🐰 Hop, hop, hooray! A type-annotation migration spree,
From Optional dreams to X | None decree,
Built-in generics now dance, so bright and so free,
Modern Python 3.10+ for all to see! ✨

Pre-merge checks and finishing touches

✅ Passed checks (3 passed)
Check name Status Explanation
Description Check ✅ Passed Check skipped - CodeRabbit’s high-level summary is enabled.
Title Check ✅ Passed The PR title "[Lint] Enable pyupgrade linter in ruff" accurately describes the primary objective and main action of this pull request. The title clearly indicates that the change is about enabling pyupgrade (UP) linting rules in the ruff configuration, which aligns with the stated PR objectives. While the changeset contains extensive code refactoring (type annotation modernization across hundreds of files to comply with the new linting rules), these changes are the logical implementation of enabling the linter rather than separate modifications. The title is concise, specific (mentioning both "pyupgrade" and "ruff"), and sufficiently clear that a developer scanning the repository history would immediately understand this is about enabling new linting rules. The instruction that titles don't need to cover every detail of the changeset supports the appropriateness of this focused title.
Docstring Coverage ✅ Passed No functions found in the changes. Docstring coverage check skipped.

78-81: Guard attrs["global_symbol"] access on PrimFunc
Accessing func_or_mod.attrs["global_symbol"] may KeyError if the attribute isn’t set (e.g. PrimFunc created in parser). Use attrs.get("global_symbol") with a clear fallback or assert its presence before indexing.

🧹 Nitpick comments (2)
tilelang/carver/roller/shape_inference/tir.py (1)

354-354: LGTM: Modernized string formatting.

The f-string is clearer and more readable than the old % formatting style.

For completeness, the static analysis tool suggests considering TypeError for invalid type errors and potentially creating a custom exception class, but these are minor style improvements that can be deferred.

tilelang/carver/roller/node.py (1)

304-304: LGTM: Simplified decorator syntax.

The simplified @functools.lru_cache (without parentheses) is valid and cleaner in Python 3.8+.

Note: Static analysis warns that using lru_cache on instance methods can lead to memory leaks because the cache holds references to self, preventing garbage collection. This is an existing pattern in the codebase and not introduced by this change, but consider whether these methods truly need caching on instance methods or if the cache should be cleared when instances are no longer needed.

264-264: Consider reverting to list comprehension for clarity.

While unpacking a generator expression is syntactically valid, it's less common and arguably less clear than the list comprehension. For 5 elements, the memory/performance benefit is negligible.

If you prefer the more conventional pattern, apply this diff:

-        do, q, k, v, o = (maybe_contiguous(x) for x in (do, q, k, v, o))

tilelang/jit/adapter/cython/adapter.py (1)

105-105: LGTM! Default file mode usage.

Removing the explicit "r" mode is correct since Python defaults to text read mode. This modernization aligns with pyupgrade linter rules and makes the code cleaner without changing behavior.

Also applies to: 118-118, 135-135

examples/grouped_gemm/example_grouped_gemm_bwd.py (1)

139-139: Confirm generator-expression change
The switch from [maybe_contiguous(x) for x in …] to (maybe_contiguous(x) for x in …) for immediate unpacking isn’t a known pyupgrade rule and offers no benefit. Verify this refactor is intentional and actually produced by your pyupgrade/ruff setup (e.g., share your lint output or rule config).

357-357: Good f-string conversion with minor optimization opportunity.

The f-string conversion improves readability. Consider simplifying further by eliminating the concatenation:

-    print(name + f"  all_close={all_close}")
+    print(f"{name}  all_close={all_close}")

examples/grouped_gemm/example_grouped_gemm_bwd.py (1)

139-139: Consider using map() for better idiomaticity.

The generator expression works correctly but is unconventional for immediate unpacking. The map() builtin is the standard Python pattern for applying a function to multiple values.

Apply this diff to use the more idiomatic map():

-        A, B, batch_sizes = (maybe_contiguous(x) for x in (A, B, batch_sizes))
+        A, B, batch_sizes = map(maybe_contiguous, (A, B, batch_sizes))
setup.py (1)

312-312: Remove the unused noqa directive.

The # noqa: SIM115 comment is no longer needed since the code has been updated to address the linting issue.

Apply this diff:

-        return open(get_path("README.md"), encoding="utf-8").read()  # noqa: SIM115
+        return open(get_path("README.md"), encoding="utf-8").read()
tilelang/carver/roller/shape_inference/tir.py (1)

354-354: F-string migration looks good; consider using TypeError for type errors.

The f-string conversion is correct. As an optional improvement, consider raising TypeError instead of generic Exception when encountering unexpected types, as this provides clearer intent.

Apply this diff if desired:

-        raise Exception(f"Unhandled node type in walk_indice(): {expr}")
+        raise TypeError(f"Unhandled node type in walk_indice(): {type(expr).__name__}")

11-12: Ensure subclasses of GemmBase remain instantiable after removing @dataclass.

Removing @dataclass drops the generated __init__, so any subclass without its own constructor will inherit object.__init__ and break when passed gemm_node. We found no direct instantiations of GemmBase or its subclasses (tilelang/tileop/gemm/gemm_wgmma.py, tilelang/tileop/gemm/gemm_mma.py, tilelang/primitives/gemm/gemm_mma.py), but none define __init__. Confirm these classes aren’t instantiated at runtime or add explicit __init__ methods.

304-304: Verify that instance lifetime justifies method-level caching.

The static analysis tool (B019) flags that using @functools.lru_cache on methods can prevent garbage collection of instances. The cache holds references to self, which can lead to memory leaks if instances are meant to be short-lived.

If PrimFuncNode instances have long lifetimes or are reused frequently, this is acceptable. Otherwise, consider using a separate cache or @lru_cache with maxsize to limit memory growth.

Overall LGTM.

Some small nits:

  1. Add __future__ imports only when needed.

  2. We'd best add the tool.ruff.target-version to pyproject.toml when UP code is enabled.

    [tool.ruff]
    target-version = "py38"

Thanks! @XuehaiPan

  1. Add __future__ imports only when needed.

This should be covered by the added FA102 rule.

2. We'd best add the tool.ruff.target-version to pyproject.toml when UP code is enabled.

I steal a commit from your PR #955 to resolve that.

10-16: Don't use PEP 604/585 syntax under a Python 3.8 target.

The new annotations (int | None, tuple[...], bare dict) rely on PEP 604/585 features that aren’t available on Python 3.8. Even with from __future__ import annotations, any runtime evaluation of these hints (e.g. typing.get_type_hints) will raise, breaking the stated goal of keeping 3.8 compatibility.

The second definitions (lines 32, 34) overwrite the first ones (lines 17, 22), making the initial assignments redundant. This appears to be a pre-existing issue that should be addressed.

Remove the duplicate definitions and consolidate into a single set:

+        self.bandwidth: list[int] = [0, 0]

Alternatively, if the second definitions should replace the first, remove lines 17-25:

25-26: Type annotation modernization looks good.

The migration from Optional[int] to int | None syntax is correct and aligns with the PR's goal of enabling pyupgrade linter rules. The runtime behavior is unchanged since the defaults and assertions remain the same.

Optional refactor: Consider tightening the type hints.

Since both parameters have non-None defaults (4 and 32) and are immediately validated as non-None (lines 28-31), the type hints could be simplified to just int rather than int | None:

-    n_partition: int | None = 4,
-    reduce_thread: int | None = 32,
+    n_partition: int = 4,
+    reduce_thread: int = 32,

This would make the signature more accurate—the function doesn't meaningfully accept None since it's rejected immediately. However, this is a pre-existing pattern from the original Optional[int] annotations and is outside the scope of this linting PR.

1-2: Clean up unused imports and modernize type aliases for consistency.

After updating the function signatures to use built-in list, the List import from typing on line 2 is no longer used in the function signatures. Additionally, for consistency with the modernized function signatures, the type aliases TokensText (line 4) and TokensTextLogprobs (line 27) should also be updated to use built-in generics instead of Tuple and List from typing.

Apply this diff to modernize the type aliases and clean up imports:

-from typing import Dict, List, Tuple
+from typing import Dict


-TokensText = Tuple[List[int], str]
+TokensText = tuple[list[int], str]


-TokensTextLogprobs = Tuple[List[int], str, List[Dict[int, float]]]
+TokensTextLogprobs = tuple[list[int], str, list[Dict[int, float]]]

Note: If Dict is also unused elsewhere in the codebase, consider removing it too. The modernization to dict[int, float] would require postponed evaluation support, which is already enabled via the from __future__ import annotations statement.

211-211: LGTM! Type annotation correctly modernized.

The change from typing.Dict[str, str] to dict[str, str] is correct and aligns with modern Python typing practices (PEP 585). The future annotations import at line 18 ensures Python 3.8 compatibility.

Optional: Consider updating the docstring for consistency.

The docstring at line 224 still uses the old-style Dict[str, str] notation:

    Returns
    -------
    symbol_section_map: Dict[str, str]
        A map from defined global symbol to their sections

For consistency with the actual annotation, you could update it to:

     Returns

+    symbol_section_map: dict[str, str]

274-278: LGTM! Type hints modernized.

The conversion to built-in generic types (dict, int | None) is correct and consistent with PEP 585/604 standards.

Optionally, consider making the dict type more specific for better type safety:

     def __init__(self,
-                 config: dict,
+                 config: dict[str, Any],
                  gate: torch.Tensor,
                  up: torch.Tensor,
                  down: torch.Tensor,

This would require importing Any from typing if not already imported.

305-305: Remove hardcoded override of user input.

Line 305 unconditionally sets with_roller = True, overriding the CLI argument parsed on line 304. This makes the argparse setup (lines 290-295) and user input meaningless.

Given the PR's scope (linting/formatting), this appears to be a debugging artifact that was unintentionally committed.

Apply this diff to remove the hardcoded override:

     accum_dtype = "float32" if in_dtype == "int8" else "float16"
     with_roller = args.with_roller
-    with_roller = True

10-17: Critical: Incomplete fallback for missing fla dependency.

When fla import fails, chunk_gated_delta_rule_fwd_h is undefined, causing a NameError at line 299. The error message "fla not found, using tilelang implementation" is misleading—no actual fallback occurs.

Apply this diff to either skip the reference comparison gracefully or provide a proper fallback:

Option 1: Skip reference comparison when fla is unavailable

 try:
     import fla

     print(fla.__file__)
     from fla.ops.common.chunk_delta_h import chunk_gated_delta_rule_fwd_h
+    FLA_AVAILABLE = True
 except ImportError:
     print("fla not found, using tilelang implementation")
     fla = None
+    FLA_AVAILABLE = False

Then at line 298, add:

-    # fla ref
-    h_ref, V_new_ref, final_state_ref = chunk_gated_delta_rule_fwd_h(K, W, U, G, initial_state,
-                                                                     store_final_state, chunk_size,

+    if FLA_AVAILABLE:

+    else:
+        print("Skipping reference comparison (fla not available)")

354-355: Use bitwise boolean ops in Triton expressions

examples/bitnet-1.58b/load_from_quantized.py (1)

52-52: Outer parentheses are unnecessary.

The parentheses wrapping the entire expression add visual noise without improving readability or changing behavior. Consider removing them for cleaner code.

Apply this diff:

-    qmodel = (BitnetForCausalLM.from_quantized(saved_model_path,).cuda().half())
+    qmodel = BitnetForCausalLM.from_quantized(saved_model_path).cuda().half()

Note: Also removed the trailing comma in from_quantized(saved_model_path,) since it's unnecessary for a single-argument call.

201-213: Consider prefixing unused ctx parameter with underscore.

The multi-line formatting improves readability. However, the ctx parameter is unused throughout the function body. Since this helper is called from _sparse_attention.forward (line 262) and ctx is never utilized (backward pass is not implemented), consider prefixing it with an underscore (_ctx) to indicate it's intentionally unused and silence the linter warning.

Apply this diff if you want to silence the linter warning:

475-475: Consider defining a custom exception class (optional).

Static analysis flags TRY003 on this line. While the current error message is concise and clear, defining a custom exception class (e.g., class SimilarityError(AssertionError)) would align with the TRY003 guideline. However, this is a minor style concern and may be overkill for an example/benchmark file.

examples/deepseek_v32/fp8_lighting_indexer.py (1)

1-1: Consider removing or making the noqa directive more specific.

The blanket # ruff: noqa disables all ruff checks for this file, which seems to conflict with the PR's goal of enabling pyupgrade rules. If specific rules need to be suppressed, consider using targeted ignores like # ruff: noqa: UP001, UP032 instead.

examples/convolution/example_convolution.py (1)

50-51: Consider removing unused parameter overrides.

The dtype and accum_dtype parameters are immediately overridden with hardcoded values, making the function parameters ineffective. Since you're updating the function signature anyway, consider either:

  • Removing these parameters entirely (if always hardcoded), or
  • Removing lines 50-51 to honor the passed values

Note: This pattern also appears in example_convolution_autotune.py (lines 117-118), so you may want to address it consistently across related files.

examples/deepseek_mla/example_mla_decode_paged.py (1)

313-328: Note: Unused parameters in reference implementation.

The block_table and block_size parameters are unused in the reference implementation run_torch_mla. The function uses direct indexing (i * max_seqlen_pad) rather than block table lookups.

These parameters are likely kept for API consistency with run_tilelang_mla, which does use them. This is acceptable for maintaining a uniform interface, though you could consider documenting this or using leading underscore naming (e.g., _block_table) to indicate intentionally unused parameters.

If you want to explicitly mark them as intentionally unused:

 def run_torch_mla(
     q,
-    block_table,
+    _block_table,  # unused, kept for API consistency
     blocked_k,
     max_seqlen_pad,

66-93: Comprehensive documentation added.

The new docstring provides thorough documentation of the function's parameters, behavior, and requirements. While technically correct and informative, the 28-line docstring is quite verbose for an example file. Consider whether a more concise summary would suffice, reserving this level of detail for core library functions.

206-215: LGTM! Consider fixing the comment typo.

The type annotation modernization from Optional[int] to int | None is correct and aligns with PEP 604. The public API signature change is backward-compatible at runtime.

Minor: Line 215 has a typo in the comment: function'sinterface should be function's interface (missing space).

examples/attention_sink/example_mha_sink_fwd_bhsd.py (1)

169-169: LGTM! Consider fixing the comment typo.

The type annotation update and T.alloc_local usage are correct. The public API signature change maintains runtime compatibility.

Minor: Line 202 has the same typo as the first file: function's interface is missing a space between "function's" and "interface".

366-367: Verify the defensive getattr change and ensure consistency.

This change from direct attribute access to getattr() with a default is a logic improvement but appears unrelated to the pyupgrade linting objectives. While the defensive coding is good practice, note that Line 319 uses a similar pattern without this defensive check:

if self.model.get_output_embeddings().bias is not None:

For consistency, consider updating Line 319 similarly, or clarify whether this change addresses a specific issue with certain model types that lack a bias attribute.

Consider applying the same defensive pattern to Line 319:

-if self.model.get_output_embeddings().bias is not None:

1-351: Consider separating functional changes from linting fixes.

This PR mixes functional changes (lines 30-35: pass_configs addition) with linting/formatting improvements. While the linting changes are appropriate for a "Enable pyupgrade linter" PR, functional changes that alter behavior should ideally be in separate commits or PRs for easier review and potential rollback.

7-8: Consider replacing star imports.

Static analysis flags these star imports as they make it difficult to track which names are imported and can lead to namespace pollution.

Alternatively, use qualified imports:

Never mix multiple code styles, but be consistent with only one. You should revert this commit aca0569, since you may format the code with ruff format or black, which is incompatible with yapf.

19-21: Update docstrings to match modernized type hints.

The docstring still references old-style type hints (Union[...], Optional[...]) while the function signature uses the new syntax. Consider updating the docstring for consistency.

Apply this diff to update the docstring:

     Args:
-        src (Union[tir.Buffer, tir.BufferLoad, tir.BufferRegion]): Source memory region
-        dst (Union[tir.Buffer, tir.BufferLoad]): Destination memory region
-        coalesced_width (Optional[int], optional): Width for coalesced memory access. Defaults to None.
+        src (tir.Buffer | tir.BufferLoad | tir.BufferRegion): Source memory region
+        dst (tir.Buffer | tir.BufferLoad): Destination memory region
+        coalesced_width (int | None, optional): Width for coalesced memory access. Defaults to None.

29-41: Update the docstring to match the modernized return type.

The method signature correctly uses list[Hint], but the docstring at line 38 still references the old-style List[Hint].

Apply this diff to update the docstring:

         Returns:
-            List[Hint]: A list of optimization hints for hardware acceleration.
+            list[Hint]: A list of optimization hints for hardware acceleration.

tilelang/language/frame.py (1)

201-209: Update docstring to match modernized return type annotation.

The return type annotation was correctly updated to use PEP 604 syntax (PrimExpr | None), but the docstring at line 208 still references the old style (Optional[PrimExpr]). Update the docstring for consistency.

Apply this diff to update the docstring:

19-29: Fix return type mismatch between annotation and implementation.

The return type annotation is str | None, but the function never returns None—it returns either r.stdout.strip() or 'unknown' (line 29). This creates an issue: when the git command fails, the caller on line 67 (elif git_hash := get_git_commit_id():) receives 'unknown', which is truthy, causing line 68 to append 'gitunkno' to the version string.

Apply this diff to return None on error, matching the annotation and caller expectations:

     if r.returncode == 0:
         return r.stdout.strip()
     else:
-        return 'unknown'

14-42: Update docstring to match modernized type annotations.

The function signature correctly uses modern type syntax (int | None, str | list[str] | None), but the docstring still uses the old-style syntax. This creates an inconsistency between the signature and documentation.

Apply this diff to update the docstring:

9-19: Guard against None target before calling helper functions.

The function accepts target: Target | None = None, but line 16 directly calls is_cuda_target(target) and have_tma(target) without checking if target is None.

54-87: Consider updating docstrings for consistency.

The docstrings still use List[int], List[IterVar], and List[PrimExpr] in their Returns sections (lines 54, 65, 76, 87), while the actual type hints now use the built-in list[...] syntax. Updating these docstrings would improve consistency with the modernized type annotations.

Example for line 54:

90-100: Minor: Redundant exclude pattern for examples.

Line 92 excludes "examples/deepseek_v32/inference" at the top level, but line 99 uses a per-file-ignore pattern "examples/**.py" to ignore UP and FA rules for all examples. The top-level exclude is stricter (file-system level), while the per-file-ignore is rule-specific. If the intent is to exclude that specific examples directory from all linting rules, the top-level exclude is appropriate. If the intent is only to suppress UP/FA within examples (allowing other rules to apply), the per-file-ignore alone is sufficient. Consider clarifying or consolidating these patterns.

45-45: Type hint modernization looks good; consider updating docstrings for consistency.

The conversion from List[...] to list[...] is correct and aligns with the pyupgrade rules enabled in this PR. However, the docstrings still reference List (lines 51, 102), which creates a minor inconsistency with the updated type hints.

Consider updating the docstrings to match:

-        extents (List[tir.PrimExpr]): List of expressions defining the region size
+        extents (list[tir.PrimExpr]): List of expressions defining the region size
-        List[PrimExpr]: Coordinates for each dimension in the same order as `shape`.
+        list[PrimExpr]: Coordinates for each dimension in the same order as `shape`.

Additionally, verify that any from typing import List import (if present) was removed, as it's no longer needed.

1861-1861: Type annotations modernized correctly.

The function signatures have been properly updated to use PEP 604 union syntax (Span | None) instead of the legacy Optional[Span]. With the from __future__ import annotations import, these annotations will work correctly on Python 3.8+.

Optional: Consider updating docstrings for consistency.

The parameter docstrings (lines 1869, 1888, 1910) still reference Optional[Span] in prose form. While this is semantically correct and doesn't affect functionality, you could optionally update them to Span | None for consistency with the code annotations.

-    span : Optional[Span]

4-4: Type annotations modernized correctly; docstrings should also be updated for consistency.

The function signatures (lines 24, 70, 118) have been correctly updated to use PEP 604 str | None syntax. However, the docstring parameter descriptions (lines 34, 82, 129) still reference Optional[str] instead of the modernized syntax. For full consistency with the PR's modernization goals, update these docstrings to use str | None as well:

47-47: Consider adding type annotation for shape parameter.
