🧹 Nitpick comments (12)
codewiki/src/be/llm_services.py (5)
71-97: LGTM! Connection pooling implementation is sound.The
ClientManagerproperly uses an async lock for thread-safe client creation and reasonable connection limits. The client key approach based on URL and partial API key is acceptable for pooling purposes.One consideration: the
AsyncClientinstances are never explicitly closed. For long-running processes, consider adding a cleanup method or usingatexithandlers.
103-103: Use explicitOptionaltype hints per PEP 484.The
modelparameter uses implicitOptional(defaulting toNone). Modern Python style prefers explicit type annotations.+from typing import Dict, Optional, Union + def call_llm( prompt: str, config: Config, - model: str = None, + model: Optional[str] = None, temperature: float = 0.0 ) -> str:Apply similar changes to
call_llm_async_with_retry(line 134) andcall_llm_async(line 242).Also applies to: 134-134, 242-242
169-176: Usetime.monotonic()instead of deprecated event loop timing.
asyncio.get_event_loop().time()is deprecated in Python 3.10+. Usetime.monotonic()for consistent timing that doesn't depend on the event loop.+import time + for attempt in range(max_retries + 1): try: - start_time = asyncio.get_event_loop().time() + start_time = time.monotonic() response = await client.chat.completions.create( ... ) - api_time = asyncio.get_event_loop().time() - start_time + api_time = time.monotonic() - start_time
186-199: Uselogging.exceptionfor error logging to capture tracebacks.When logging errors in exception handlers,
logging.exceptionautomatically includes the traceback, which aids debugging.if not _is_retryable_error(e): - logger.error(f"Non-retryable error in LLM call: {e}") + logger.exception("Non-retryable error in LLM call") raise if attempt < max_retries: # Calculate exponential backoff delay delay = base_delay * (2 ** attempt) logger.warning(f"LLM call failed (attempt {attempt + 1}/{max_retries + 1}), " f"retrying in {delay:.2f}s: {e}") await asyncio.sleep(delay) else: - logger.error(f"LLM call failed after {max_retries + 1} attempts: {e}") + logger.exception(f"LLM call failed after {max_retries + 1} attempts")
208-236: Consider checking exception types directly for more reliable retry detection.String matching on exception messages is fragile and locale-dependent. Consider checking exception types directly for common cases.
def _is_retryable_error(exception: Exception) -> bool: import httpx from openai import APIConnectionError, RateLimitError, APIStatusError # Check known retryable exception types if isinstance(exception, ( httpx.ConnectError, httpx.TimeoutException, APIConnectionError, RateLimitError, )): return True # Check status code for APIStatusError if isinstance(exception, APIStatusError): return exception.status_code in (429, 502, 503, 504) # Fallback to string matching for unknown exceptions error_str = str(exception).lower() retryable_patterns = ['connection', 'timeout', 'rate limit', ...] return any(pattern in error_str for pattern in retryable_patterns)codewiki/src/be/performance_metrics.py (1)
120-122:api_call_timeslist is populated but never used.The
api_call_timeslist is appended to inrecord_api_call(line 166) but never read. Either remove it or implement the intended functionality (e.g., percentile calculations, histograms).def __init__(self): self.metrics: Optional[PerformanceMetrics] = None - self.api_call_times: List[float] = []And remove line 166:
def record_api_call(self, api_time: float) -> None: """Record an API call.""" if self.metrics is None: return self.metrics.record_api_call(api_time) - self.api_call_times.append(api_time)codewiki/src/be/documentation_generator.py (3)
15-15: Remove unused importcall_llm_async.
call_llm_asyncis imported but not used in this file. The file usescall_llm(synchronous) for parent module documentation generation.-from codewiki.src.be.llm_services import call_llm, call_llm_async +from codewiki.src.be.llm_services import call_llm
169-173: Usetime.monotonic()instead of deprecated event loop timing.
asyncio.get_event_loop().time()is deprecated. Usetime.monotonic()for consistent timing.+import time + # In process_with_semaphore (line 169) -start_time = asyncio.get_event_loop().time() +start_time = time.monotonic() result = await self.agent_orchestrator.process_module(...) -processing_time = asyncio.get_event_loop().time() - start_time +processing_time = time.monotonic() - start_time # In process_leaf_modules_sequential (line 260) -start_time = asyncio.get_event_loop().time() +start_time = time.monotonic() await self.agent_orchestrator.process_module(...) -processing_time = asyncio.get_event_loop().time() - start_time +processing_time = time.monotonic() - start_timeAlso applies to: 260-264
374-374: Unused loop variablemodule_name.The
module_namevariable is not used in the loop body. Use underscore to indicate intentional disuse.-for module_path, module_name in parent_modules: +for module_path, _module_name in parent_modules:codewiki/src/be/dependency_analyzer/utils/thread_safe_parser.py (3)
27-34: Eager language and pool initialization may be too strict; switch tologger.exceptionRight now the global
parser_poolis constructed at import time, which eagerly initializes all languages and will cause any import of this module to fail if a single tree‑sitter binding is missing or broken. If some grammars are optional or rarely used, consider lazy initialization (e.g., create the pool on firstget_thread_safe_parser()call and/or initialize individual languages on first use) so the rest of the system can still function when one language is unavailable.Also, in
_init_languagesyou are already re‑raising on failure; usinglogger.exceptioninstead oflogger.errorwill preserve the stack trace and address the TRY400 hint:- except Exception as e: - logger.error(f"Failed to initialize tree-sitter languages: {e}") - raise + except Exception: + logger.exception("Failed to initialize tree-sitter languages") + raiseAlso applies to: 35-66, 112-113
68-100: Tighten parser creation error handling and confirmParser(language_obj)usageThe per‑thread parser cache logic looks fine, but two refinements would help:
- Exception handling & logging. The
except Exceptionhere is quite broad and is what Ruff flags (BLE001). If tree‑sitter exposes a more specific exception type, prefer catching that instead of a blindException. Regardless, switching tologger.exceptionwill capture the traceback and satisfy TRY400:- try: - language_obj = self._language_cache[language] - parser = Parser(language_obj) - self._parser_cache[thread_id][language] = parser - logger.debug(f"Created {language} parser for thread {thread_id}") - except Exception as e: - logger.error(f"Failed to create {language} parser: {e}") - return None + try: + language_obj = self._language_cache[language] + parser = Parser(language_obj) + self._parser_cache[thread_id][language] = parser + logger.debug(f"Created {language} parser for thread {thread_id}") + except Exception: + logger.exception(f"Failed to create {language} parser") + return None
- API compatibility. This relies on your
tree_sitterversion supportingParser(language_obj)and on the per‑language modules returning a compatibleLanguagewhen wrapped viaLanguage(...). If your installed versions differ, you may need to switch toparser = Parser(); parser.set_language(language_obj)and/or skip the extraLanguage(...)wrapping.Please double‑check these assumptions against the exact
tree_sitterand grammar package versions used in this repo.
102-109: Explicit thread cleanup is easy to forget; consider reducing the need for it
cleanup_thread()correctly removes the current thread’s parsers, but it relies on every worker thread remembering to call it. If you create many short‑lived threads without cleanup,_parser_cachecan grow and, in extreme cases, reused thread IDs might see stale parsers.Two options to reduce this risk:
- Wrap thread usage behind a small helper that always calls
cleanup_current_thread()infinally, or- Move the per‑thread cache to a
threading.local()attribute so Python handles lifecycle automatically andcleanup_thread()becomes mostly unnecessary.Given the likely small number of worker threads, this is mostly a robustness/maintenance improvement.

54-59: LGTM! New configuration fields are well-structured.The new fields for token configuration and parallel processing have sensible defaults sourced from existing constants. Using dataclass field defaults ensures backward compatibility.
89-94: Verify consistency withfrom_argsfactory method.The
from_climethod now accepts and forwards the new parallel processing parameters, butfrom_args(lines 62-78) doesn't support these parameters and will use dataclass defaults. This is likely intentional for backward compatibility, but verify that CLI argument parsing doesn't need these options.Also applies to: 127-131
codewiki/cli/models/config.py (3)
39-42: LGTM! New CLI configuration fields align with backend.The new fields match the backend
Configclass defaults and are properly forwarded into_backend_config.

from_dictmethod only deserializesbase_url,main_model,cluster_model, anddefault_output.

108-112: LGTM! Backend config forwarding is complete.All new configuration fields are correctly forwarded to
Config.from_cli.codewiki/src/be/performance_metrics.py (2)
13-27: LGTM! Well-structured metrics dataclass.The
PerformanceMetricsdataclass provides comprehensive tracking for documentation generation with clear separation of concerns.
65-73: Verify the parallel efficiency calculation formula.The current formula calculates
theoretical_parallel_time / actual_time, which yields:
> 1when actual time is better than theoretical (unexpected for conservative parallelization)< 1when actual time is worse than theoreticalTypical parallel efficiency is defined as
speedup / concurrency = (sequential_time / parallel_time) / concurrency. Consider if the formula matches your intended semantics.# Alternative: standard parallel efficiency formula self.parallel_efficiency = (sequential_time_estimate / self.total_time) / self.concurrency_limitcodewiki/src/be/documentation_generator.py (2)
156-166: Potential race condition when loading module_tree in parallel.Each parallel task loads
module_treefrom the same JSON file (lines 160-166). Ifagent_orchestrator.process_modulemodifies and saves this file, concurrent tasks may read stale or partially-written data.Consider either:
- Loading the module tree once before parallel processing and passing it to tasks
- Adding file locking for concurrent access
- Ensuring
process_moduledoesn't modify the shared file during parallel leaf processing
352-355: LGTM! Performance tracking integration is well-placed.The tracking is correctly started before module processing with accurate counts and stopped after completion with metrics logging. This provides good observability for the parallel processing feature.
Also applies to: 494-497

19-34: Solid separation of shared languages vs per‑thread parsersThe overall pool design—shared
Languagecache plus per‑threadParserinstances behind a lock—fits the parallel parsing goal well and avoids cross‑thread parser reuse. The docstring clearly captures the intent.

codewiki/src/be/llm_services.py (4)
69-95: Consider adding client cleanup for long-running processes.The
ClientManagercaches clients indefinitely without a cleanup mechanism. For long-running processes with changing configurations, this could lead to stale connections accumulating.Consider adding a
close_all()method for graceful shutdown:class ClientManager: """Manages async OpenAI clients with connection pooling.""" def __init__(self): self._clients: Dict[str, AsyncOpenAI] = {} self._lock = asyncio.Lock() + async def close_all(self) -> None: + """Close all cached clients.""" + async with self._lock: + for client in self._clients.values(): + await client.close() + self._clients.clear() + async def get_client(self, config: Config) -> AsyncOpenAI:
129-137: Use explicitOptionaltype hints per PEP 484.The
modelparameter uses implicitOptionalwhich is discouraged.async def call_llm_async_with_retry( prompt: str, config: Config, - model: str = None, + model: Optional[str] = None, temperature: float = 0.0, max_tokens: Optional[int] = None, max_retries: int = 3, base_delay: float = 1.0 ) -> str:Apply the same fix to
call_llm(line 101) andcall_llm_async(line 240).
184-197: Uselogger.exceptionto preserve stack traces.When logging errors during exception handling,
logger.exceptionautomatically includes the traceback which aids debugging.# Check if this is a retryable error if not _is_retryable_error(e): - logger.error(f"Non-retryable error in LLM call: {e}") + logger.exception("Non-retryable error in LLM call") raise if attempt < max_retries: # Calculate exponential backoff delay delay = base_delay * (2 ** attempt) logger.warning(f"LLM call failed (attempt {attempt + 1}/{max_retries + 1}), " f"retrying in {delay:.2f}s: {e}") await asyncio.sleep(delay) else: - logger.error(f"LLM call failed after {max_retries + 1} attempts: {e}") + logger.exception(f"LLM call failed after {max_retries + 1} attempts")
206-234: Consider type-based exception checking for robustness.String-based pattern matching on exception messages can be fragile if error messages change. Consider supplementing with type-based checks for common exception types.
def _is_retryable_error(exception: Exception) -> bool: # Type-based checks first import httpx if isinstance(exception, (httpx.TimeoutException, httpx.NetworkError)): return True # Fall back to string matching for other cases error_str = str(exception).lower() # ... existing pattern matchingcodewiki/src/be/performance_metrics.py (1)
164-170:api_call_timeslist is collected but not utilized.The
api_call_timeslist accumulates individual API call durations but is never used for reporting or analysis. Consider either removing it or exposing it into_dict()for detailed API timing analysis (e.g., percentiles).codewiki/src/be/documentation_generator.py (4)
159-166: Potential I/O contention from repeated file reads in parallel tasks.Each parallel task loads
module_tree.jsonindependently (line 161). With high concurrency, this causes redundant I/O. Consider passing the relevant module info as a parameter to avoid repeated file reads.If the tree structure is static during leaf processing, pre-extract module info before spawning tasks:
# Pre-extract module info before parallel processing module_infos = {} module_tree = file_manager.load_json(module_tree_path) for module_path, module_name in leaf_modules: module_key = "/".join(module_path) info = module_tree for path_part in module_path: info = info[path_part] if path_part != module_path[-1]: info = info.get("children", {}) module_infos[module_key] = infoThen pass
module_infos[module_key]to each task.
180-183: Uselogger.exceptionto preserve stack traces.Within exception handlers, use
logger.exceptioninstead oflogger.errorto automatically include the full traceback for debugging.except Exception as e: - logger.error(f"Failed to process leaf module {module_key}: {str(e)}") + logger.exception(f"Failed to process leaf module {module_key}") performance_tracker.record_module_processing(False, 0) return module_key, FalseApply the same pattern at lines 261-262, 310-311, and 375-376.
366-377: Unused loop variablemodule_name.The
module_namevariable is unpacked but not used in the loop body.- for module_path, module_name in parent_modules: + for module_path, _ in parent_modules: module_key = "/".join(module_path)
486-489: Parallel efficiency not calculated.
stop_tracking()is called withoutsequential_time_estimate, soparallel_efficiencywill always be 0. Consider estimating sequential time (e.g.,avg_api_time * total_modules) to calculate meaningful efficiency metrics.# Stop performance tracking and calculate metrics - metrics = performance_tracker.stop_tracking() + # Estimate sequential time for efficiency calculation + sequential_estimate = metrics.avg_api_time * metrics.total_modules if metrics.api_calls > 0 else None + metrics = performance_tracker.stop_tracking(sequential_time_estimate=sequential_estimate)Note: This would require calling
get_current_metrics()beforestop_tracking()to accessavg_api_time.

170-170: Local variable result is assigned to but never used
Remove assignment to unused variable result
(F841)
178-178: Consider moving this statement to an else block
(TRY300)
🤖 Prompt for AI Agents
In codewiki/src/be/documentation_generator.py around lines 168 to 178, the value
returned from await self.agent_orchestrator.process_module(...) is assigned to
result but never used; remove the unused variable by awaiting the call without
assigning (or, if the returned value is needed, propagate or use it where
appropriate) and keep timing/metrics recording and return unchanged.

🧹 Nitpick comments (11)
codewiki/src/be/caching.py (2)
104-108: Consider usingOrderedDictfor O(1) LRU operations.The current implementation uses
list.remove(key)which is O(n). For the defaultmax_size=1000, this is acceptable, but if cache size increases, performance will degrade. Python'scollections.OrderedDictwithmove_to_end()provides O(1) LRU semantics.-from typing import Optional, Dict, Any +from typing import Optional, Any +from collections import OrderedDict class LLMPromptCache: def __init__(self, max_size: int = 1000): self.max_size = max_size - self._cache: Dict[str, str] = {} - self._access_order: list[str] = [] + self._cache: OrderedDict[str, str] = OrderedDict() - def _update_access_order(self, key: str) -> None: - """Update access order for LRU.""" - if key in self._access_order: - self._access_order.remove(key) - self._access_order.append(key) + def _update_access_order(self, key: str) -> None: + """Update access order for LRU.""" + self._cache.move_to_end(key)
116-128: Consider limiting keys returned inget_stats().Returning all cache keys (line 127) could be memory-intensive for large caches during debugging/monitoring. Consider returning only the count or a sample.
def get_stats(self) -> Dict[str, Any]: return { "size": len(self._cache), "max_size": self.max_size, "utilization": len(self._cache) / self.max_size if self.max_size > 0 else 0, - "keys": list(self._cache.keys()) + "hit_rate": 0.0, # Consider tracking hits/misses for better stats }codewiki/src/be/dependency_analyzer/analyzers/c.py (1)
7-8: Unused imports after thread-safe parser refactor.After switching to
get_thread_safe_parser(), thetree_sitter_cimport (line 8) and possiblyLanguage(line 7) appear unused. The parser pool handles language initialization internally.-from tree_sitter import Parser, Language -import tree_sitter_c +from tree_sitter import Parsercodewiki/src/be/dependency_analyzer/analyzers/csharp.py (1)
7-8: Unused imports after thread-safe parser refactor.Similar to other analyzers,
tree_sitter_c_sharp(line 8) andLanguage(line 7) appear unused after the refactor.-from tree_sitter import Parser, Language -import tree_sitter_c_sharp +from tree_sitter import Parsercodewiki/src/be/dependency_analyzer/analyzers/cpp.py (1)
7-8: Unused imports after thread-safe parser refactor.
tree_sitter_cpp(line 8) andLanguage(line 7) appear unused.-from tree_sitter import Parser, Language -import tree_sitter_cpp +from tree_sitter import Parsercodewiki/src/be/dependency_analyzer/analyzers/javascript.py (1)

30-42: New CLI configuration fields and backend forwarding are consistentThe added fields (
max_tokens_per_module,max_tokens_per_leaf,enable_parallel_processing,concurrency_limit) are documented, have sane defaults, and are populated consistently infrom_dict.to_backend_configcorrectly forwards them intoConfig.from_cli, so the new settings should propagate end-to-end without breaking existing call sites.Also applies to: 70-79, 106-117
codewiki/src/be/llm_services.py (3)
74-100: Consider adding explicit client lifecycle management.The
ClientManagercreateshttpx.AsyncClientinstances but never closes them. While Python's garbage collector will eventually clean up, it's better practice to explicitly manage async client lifecycle to ensure connections are properly closed, especially under high load.Consider adding an async cleanup method:
class ClientManager: """Manages async OpenAI clients with connection pooling.""" def __init__(self): self._clients: Dict[str, AsyncOpenAI] = {} self._lock = asyncio.Lock() + + async def cleanup(self): + """Close all async clients and release resources.""" + async with self._lock: + for client in self._clients.values(): + await client.close() + self._clients.clear()Alternatively, implement
__aenter__and__aexit__to support usage as an async context manager.
106-108: Consider explicit type union syntax for optional parameters.Parameters with
Nonedefaults should use explicitstr | Nonesyntax per PEP 484 for clarity.Apply this pattern to improve type hints:
async def call_llm_async_with_retry( prompt: str, config: Config, - model: str = None, + model: str | None = None, temperature: float = 0.0, - max_tokens: Optional[int] = None, + max_tokens: int | None = None, max_retries: int = 3, base_delay: float = 1.0 ) -> str:Based on static analysis hints (Ruff RUF013).
Also applies to: 137-139, 258-260
224-252: Consider checking exception types in addition to error messages.The string-based pattern matching is a good fallback, but structured exception type checking would be more reliable for known error classes from httpx and openai libraries.
Enhance the function to check exception types first:
def _is_retryable_error(exception: Exception) -> bool: """ Determine if an exception is retryable. Args: exception: The exception to check Returns: True if the exception should be retried """ + # Check exception types first + import httpx + from openai import RateLimitError, APITimeoutError, APIConnectionError + + if isinstance(exception, ( + httpx.TimeoutException, + httpx.ConnectError, + RateLimitError, + APITimeoutError, + APIConnectionError + )): + return True + + # Fallback to string matching for unstructured errors error_str = str(exception).lower() # Network-related errors retryable_patterns = [ 'connection', 'timeout', 'network', 'rate limit', 'too many requests', 'temporary', 'service unavailable', 'internal server error', '503', '502', '504', '429' ] return any(pattern in error_str for pattern in retryable_patterns)test_phase2_verify.py (1)
1-1: Consider making the verification script executable.The shebang is present but the file isn't marked executable. If this script is intended to be run directly (
./test_phase2_verify.py), add execute permissions.chmod +x test_phase2_verify.pyBased on static analysis hints (Ruff EXE001).

16-24: Lazy imports pattern looks good.The function-based lazy imports effectively avoid circular dependency issues between llm_services, performance_metrics, and caching modules.
134-221: Retry logic and caching integration look solid.The exponential backoff implementation is correct, cache integration is appropriate, and error handling properly distinguishes retryable from non-retryable errors. The loop structure
range(max_retries + 1)correctly provides an initial attempt plus retries.codewiki/cli/commands/config.py (3)
53-70: CLI option definitions look good.The new parallel processing options are well-defined with appropriate constraints (
IntRange(1, 10)) and follow Click's conventions for boolean flags and optional parameters.
93-129: Validation and save flow implemented correctly.The
is not Nonechecks properly handle boolean flags, and the validated data flows correctly through toConfigManager.save.
162-168: Display and output formatting look good.The new configuration fields are properly displayed in both JSON and human-readable formats, with appropriate default values and consistent styling.
Also applies to: 224-228, 257-267
test_phase2_verify.py (2)
12-76: Basic functionality test looks reasonable for verification.The string-based checks are pragmatic for a verification script, though they could match false positives (e.g., in comments). For this use case, the approach is acceptable.
78-114: Language analyzer verification is thorough.The test correctly verifies thread-safe parser integration across all supported language analyzers and checks for removal of direct parser creation patterns.
codewiki/src/config.py (2)
54-61: New configuration fields look good.The added fields have appropriate types and default values that align with the PR objectives (conservative defaults for Phase 1 parallelization).
79-82: Configuration initialization is consistent.Both
from_argsandfrom_cliproperly initialize the new fields, withfrom_cliproviding full parameter control whilefrom_argsuses sensible defaults.Also applies to: 94-98, 111-114, 132-136
codewiki/src/be/dependency_analyzer/analysis/call_graph_analyzer.py (5)
30-54: Analysis routing logic is well-designed.The conditional routing between parallel and sequential analysis based on
enable_paralleland file count is sensible, avoiding parallel overhead for single files.
55-110: Parallel analysis implementation is well-architected.Key design strengths:
- Grouping files by language reduces parser pool contention
- Conservative max_workers limit (4) appropriate for Phase 1
- Resilient error handling that continues processing other languages
- Thread-safe state management with explicit locks
140-171: Per-language processing is thread-safe.The pattern of accumulating results in local collections then merging under locks is correct and avoids race conditions on shared state.
173-204: Thread-safe analyzer variants are correctly implemented.The
_safevariants properly return results instead of mutating shared state, enabling safe parallel execution. The code duplication is necessary to maintain thread safety while preserving the existing sequential API.Also applies to: 304-321, 349-367, 394-412, 435-446, 468-481, 504-519, 543-558
72-91: ThreadPoolExecutor resource management is correct.The context manager ensures proper cleanup of the thread pool, preventing resource leaks.

However, verification reveals a critical mismatch: Config defines enable_parallel_processing (line 58 in codewiki/src/config.py), but AnalysisService looks for enable_parallel_analysis (lines 80, 289 in codewiki/src/be/dependency_analyzer/analysis/analysis_service.py). Because AnalysisService uses getattr(self.config, 'enable_parallel_analysis', True) with a default, the code does not crash—but Config.enable_parallel_processing is never actually used. Align the attribute names so the parallel processing configuration is properly respected. test_phase2_core.py lines 81-101 (and also apply small fixes in 116-148): the In test_phase2.py around lines 49-76 (and also apply the third fix around lines |

84-136: LGTM—clean integration of new configuration parameters.The addition of
enable_parallel_processingandconcurrency_limitparameters is well-implemented:
- Backward-compatible optional parameters with sensible defaults
- Clear documentation in the docstring
- Consistent conditional assignment pattern matching existing fields
- Proper integration with the updated
ConfigurationmodelThe changes align correctly with the Phase 2 parallel processing features.
codewiki/src/be/caching.py (3)
17-36: LGTM! Thread safety properly implemented.The addition of
threading.RLock()at line 35 addresses the thread-safety concern raised in previous reviews. UsingRLockis appropriate as it allows re-entrant calls from the same thread.
82-106: LGTM! Access order bug fixed.The
set()method now correctly calls_update_access_order(key)at line 103 for all cache writes, ensuring that both new entries and updates to existing entries properly refresh their LRU position. This addresses the premature eviction issue noted in previous reviews.
135-181: LGTM! Clean public API design.The global cache instance and public API functions provide a clean, simple interface for LLM response caching. All operations correctly delegate to the singleton
LLMPromptCacheinstance, which handles synchronization internally.

Perfect! I've fixed the thread safety issue in the
The fix addresses the specific concern mentioned in the PR comment about race conditions when reading cache state without synchronization. This is particularly important in the parallel processing context that this PR enables, where multiple threads might be accessing the cache concurrently. The implementation follows the same pattern used by other methods in the class ( |
