Add comprehensive docstrings to utility functions and helper classes #146
Conversation
This commit adds detailed docstrings to various utility functions, helper classes, and internal methods across the key-value-aio package, improving code documentation and API clarity. Elasticsearch utilities: - Add docstrings to 10 utility functions in elasticsearch/utils.py - Document response parsing, field extraction, and document conversion - Add detailed explanations of nested Elasticsearch response structures Windows Registry utilities: - Add docstrings to 7 helper functions in windows_registry/utils.py - Document registry operations (get, set, delete, create) - Add context manager documentation for error handling Store implementations: - Add sanitize_key() docstring for MemcachedStore - Add helper function docstrings for ElasticsearchStore - Enhance SimpleStoreEntry dataclass with method docstrings - Enhance MemoryCacheEntry dataclass with comprehensive docstrings - Add MemoryCollection class and method docstrings - Document memory cache TTU and size calculation functions Statistics wrappers: - Enhance all statistics dataclass docstrings - Clarify purpose of each statistics type (Get, Put, Delete, TTL, Exists) - Add detailed documentation for collection and store-level statistics - Document the get_collection() aggregation method All changes follow Google-style docstring format and maintain consistency with existing documentation patterns. Ready for mkdocstrings generation.

📝 WalkthroughWalkthroughThis pull request enhances documentation and refactors error handling across the key-value storage library. Changes include extensive docstring additions across multiple store implementations, refactoring of memory cache entry handling to remove TTL field, replacement of context manager error handling with explicit exception handling in Windows Registry utilities, addition of input validation in Elasticsearch utilities, and expansion of statistics tracking capabilities.

96-106: Well-documentedkeys()method with clear parameter and return documentation.The docstring accurately reflects the implementation: the limit is clamped to a maximum of
PAGE_LIMIT(10,000), and keys are returned as a sliced list. The documentation clearly explains both the default behavior and the boundary enforcement.key-value/key-value-aio/src/key_value/aio/stores/windows_registry/utils.py (3)
7-23: LGTM! Clean implementation with proper error handling.The docstring is clear, the return type correctly indicates
Nonefor missing keys/values, and exception handling is appropriate.
39-55: LGTM! Consistent error handling pattern.The function correctly returns
Falsewhen the value doesn't exist or can't be deleted, providing a clean API for callers.

65-86: Critical: Remove side effect that mutates expires_at during TTU calculation.Line 84 mutates
value.expires_atinside the TTU calculation function. This is problematic:
- Overwrites original expiration: The TTU function recalculates expiration as
now + ttl_at_insert, which may differ from the originalexpires_atvalue that was carefully set when the ManagedEntry was created.- Violates function purity: TTU calculations should be pure functions that compute and return values, not mutate cache entries.
- Hidden side effects: TLRUCache may call this function multiple times during its lifetime, causing repeated mutations that are not apparent to callers.
- Undocumented: The docstring doesn't mention this mutation, making it a hidden behavior.
The
expires_atshould be set once at insertion time inMemoryCacheEntry.from_managed_entry()orMemoryCollection.put(), and the TTU function should only calculate and return the expiration timestamp without modifying the entry.Apply this diff to remove the mutation:
def _memory_cache_ttu(_key: Any, value: MemoryCacheEntry, now: float) -> float: """Calculate time-to-use for cache entries based on their TTL. This function is used by TLRUCache to determine when entries should expire. - It calculates the expiration timestamp and updates the entry's expires_at field. + It calculates the expiration timestamp from the TTL at insertion time. Args: _key: The cache key (unused). value: The cache entry. now: The current time as an epoch timestamp. Returns: The expiration time as an epoch timestamp, or sys.maxsize if the entry has no TTL.

27-62: LGTM: Well-documented dataclass and conversion methods.The docstrings clearly explain the purpose of MemoryCacheEntry and its conversion methods. The documentation follows Google style consistently.
89-101: LGTM: Clear documentation of entry counting strategy.The docstring effectively explains why the function returns 1 (entry-based limiting rather than memory-based) and its integration with TLRUCache.
110-115: LGTM: Clear class documentation.The class docstring succinctly describes the purpose and key characteristics (TTL-based expiration, automatic eviction).
131-147: LGTM: Well-documented get method.The docstring clearly describes the retrieval behavior and return values.
160-169: LGTM: Clear delete method documentation.The docstring accurately describes the deletion behavior and return semantics.
171-181: LGTM: Well-documented keys method.The docstring clearly explains the limit parameter and return value. The implementation correctly enforces the limit on line 180.

7-23: LGTM! Clear and accurate docstring.The docstring accurately describes the function's behavior, parameters, and return values. The error handling is appropriate for registry operations.
46-62: LGTM! Comprehensive docstring.The docstring clearly documents the function's purpose, parameters, and return behavior.
65-79: LGTM! Clear docstring.The docstring accurately describes the key existence check behavior.
100-115: LGTM! Improved clarity.The explicit
else: return Truemakes the success case clearer, and the docstring is comprehensive.
118-141: Past enumeration bugs fixed; non-recursive behavior confirmed correct.Verification confirms the implementation is now sound:
✅ Enumeration logic corrected: Always uses index 0; keys shift after deletion
✅ Loop termination corrected: CatchesOSErrorfromEnumKeywhen exhausted
✅ Non-recursive behavior intentional and correct: Registry structure stores collections as immediate subkeys with values (not nested keys) within them. Deleting collection subkeys removes all associated data.
✅ Exception handling appropriate: Uses specific exceptions (FileNotFoundError,OSError)
✅ Docstring accurate: Clearly states "non-recursive" behaviorOptional refinement: Consider explicit
try-exceptinstead ofcontextlib.suppressfor readability:- with contextlib.suppress(FileNotFoundError, OSError): - winreg.DeleteKey(reg_key, next_child_key) + try: + winreg.DeleteKey(reg_key, next_child_key) + except (FileNotFoundError, OSError): + passThis is a style preference, not a correctness issue.

expires_atmutation in_memory_cache_ttu). The documentation quality is excellent and will support automated documentation generation.Note: This approval is for the docstring quality only. The underlying concern about this being a generated file and the expires_at recalculation behavior are addressed in separate comments.
Also applies to: 44-52, 56-60, 65-77, 89-99, 110-114, 127-134, 156-163, 167-174
1-3: Incorrect review comment — generated file was properly regenerated from async source.The sync file was not directly edited. Analysis of the commit history shows:
- Comprehensive docstrings were added to the async source file in an earlier commit
- In the current commit, both the async file received the
recalculate_ttl()fix and the sync file was regenerated to match, pulling docstrings from the async source viabuild_sync_library.py- The docstrings in the generated sync file are identical to those in the async source, confirming proper regeneration
The proper workflow was followed: changes were made to the async source, and the sync package was regenerated to match. No guidelines were violated.
Likely an incorrect or invalid review comment.
145-153: This review comment targets a generated file and should not be pursued.The file
key-value/key-value-sync/src/key_value/sync/code_gen/stores/memory/store.pyis automatically generated from its async counterpart inkey-value/key-value-aioviabuild_sync_library.py. The coding guidelines explicitly state: "Never edit files in key-value/key-value-sync; the sync package is generated and changes will be overwritten."Additionally, the behavior being questioned—the
expires_atmutation—is intentional and documented. The_memory_cache_ttufunction docstring explicitly states it "updates the entry's expires_at field" (line 68), making this an expected side effect of the TLRUCache callback mechanism.If a concern about this behavior exists, it should be raised against the source file (
key-value/key-value-aio/src/key_value/aio/stores/memory/store.py) where actual changes are made.Likely an incorrect or invalid review comment.

🟡 Issue That Needs Clarification (Not Necessarily a Fix)3. TTL recalculation bug in CodeRabbit claims this is a "Major" bug, but I've verified the logic: # Current code:
value.recalculate_ttl()
self._cache[key] = MemoryCacheEntry.from_managed_entry(managed_entry=value, ttl=value.ttl)The claim: The reality:
Testing the scenario: # Scenario: Entry created at t=0 with ttl=60
entry = ManagedEntry(value={}, ttl=60)
# __post_init__ sets expires_at = now + 60s
# 10 seconds later, we call put()
value.recalculate_ttl() # This does nothing because ttl=60 (not None)
# Entry is stored with ttl=60 (original value)Is this a bug? 🤔
Question for you: Do you expect 🔴 Real Issues That Should Be Addressed4. Windows Registry functions ignore bool return values (lines 81, 100) Issue: Both # Line 81: Ignores return value

The Real Bug
CodeRabbit identified a real issue in lines 156-158:
# Line 156-157: This doesn't work!
value.recalculate_ttl() # Only works if ttl is None
self._cache[key] = MemoryCacheEntry.from_managed_entry(managed_entry=value, ttl=value.ttl)Problem: If a ManagedEntry is created with ttl=60, then __post_init__ sets expires_at. Later when we call recalculate_ttl(), it checks if self.expires_at is not None and self.ttl is None: — but ttl is not None, so it doesn't recalculate!
Scenario:
- t=0: Create
ManagedEntry(ttl=60)→ setsexpires_at = t+60,ttl=60 - t=10: Call
put(key, entry) recalculate_ttl()does nothing (ttl is not None)- Stores with
ttl=60instead of remainingttl=50 - Entry expires 10 seconds late!
Recommendation: Yes, pass expires_at instead! ✅
Your suggestion is exactly right and would fix multiple issues:
- Fixes the bug: No need for
recalculate_ttl()- we'd use the already-computedexpires_at - Removes side effects: No mutation in
_memory_cache_ttu - Clearer semantics: Store what we actually care about (absolute expiration time)
- Simpler logic: Less indirection between TTL ↔ expires_at
Proposed Implementation
@dataclass
class MemoryCacheEntry:
json_str: str
expires_at: datetime | None
@classmethod
def from_managed_entry(cls, managed_entry: ManagedEntry) -> Self:
"""Create a cache entry from a ManagedEntry.
Args:
managed_entry: The ManagedEntry to convert.
Returns:
A new MemoryCacheEntry.
"""
return cls(
json_str=managed_entry.to_json(),
expires_at=managed_entry.expires_at, # Use the absolute timestamp
)
def _memory_cache_ttu(_key: Any, value: MemoryCacheEntry, now: float) -> float:
"""Calculate time-to-use for cache entries based on their expiration time.
This function is used by TLRUCache to determine when entries should expire.
Args:
_key: The cache key (unused).
value: The cache entry.
now: The current time as an epoch timestamp (unused).
Returns:
The expiration time as an epoch timestamp, or sys.maxsize if the entry has no TTL.
"""
if value.expires_at is None:
return float(sys.maxsize)
return value.expires_at.timestamp()
# In put():
def put(self, key: str, value: ManagedEntry) -> None:
"""Store an entry in the collection.
Args:
key: The key to store under.
value: The ManagedEntry to store.
"""
# No recalculate_ttl() needed - expires_at is already correct!
self._cache[key] = MemoryCacheEntry.from_managed_entry(managed_entry=value)Benefits:
- ✅ No
ttl_at_insertfield needed - ✅ No mutation in
_memory_cache_ttu - ✅ Simpler
from_managed_entrysignature (nottlparameter) - ✅ Fixes the stale TTL bug
- ✅ More intuitive: "when does this expire?" vs. "how long did it last when inserted?"
Would you like me to implement this refactoring?

This refactoring addresses CodeRabbit's feedback by: - Removing the ttl_at_insert field from MemoryCacheEntry - Storing expires_at directly instead of calculating it on-the-fly - Eliminating the side effect mutation in _memory_cache_ttu - Fixing the stale TTL bug where recalculate_ttl() wouldn't work - Simplifying the code with clearer semantics Benefits: - No more problematic side effects - Fixes TTL recalculation bug automatically - Clearer code: we store what we actually use (expires_at) - Less indirection between TTL and expires_at Co-authored-by: William Easton <strawgate@users.noreply.github.com>

key-value/key-value-aio/src/key_value/aio/stores/memory/store.py (7)
24-57: LGTM: Clean migration to expires_at-based expiration.The removal of the
ttlparameter fromfrom_managed_entrysimplifies the API and correctly relies onexpires_atas the absolute expiration timestamp. This design is cleaner than the previous TTL recalculation approach and properly addresses the past review concern about TTL handling.
79-91: LGTM: Clear documentation of entry-counting behavior.The docstring effectively explains why this function returns 1 regardless of actual memory usage, making the design decision transparent.
100-106: LGTM: Clear class-level documentation.The docstring effectively describes the class's role as a TTL-aware, size-limited cache wrapper.
121-138: LGTM: Clear documentation of retrieval behavior.The docstring accurately describes the method's behavior. Note that expiration checking is handled by TLRUCache via the
ttufunction, not in this method.
139-146: LGTM: Correctly addresses past review comment on TTL handling.The new implementation properly resolves the TTL recalculation issue flagged in the past review. By directly using
expires_atfromManagedEntry(an absolute timestamp set at creation time), the code avoids the complexity of recalculating remaining TTL at insertion time.How it works:
ManagedEntrycreated withttl=60at t=0 →__post_init__setsexpires_at = t+60- Entry inserted at t=10 →
from_managed_entrycopiesexpires_at = t+60TLRUCacheuses_memory_cache_ttuwhich returnsexpires_at.timestamp() = t+60- Entry expires at absolute time t+60 (50 seconds after insertion)
This design correctly uses absolute expiration times and is cleaner than the previous TTL recalculation approach.
148-157: LGTM: Clear documentation of deletion behavior.The docstring accurately describes the boolean return semantics.
159-169: LGTM: Clear documentation of key enumeration.The docstring accurately describes the limiting behavior with the 10,000 default.

1-3: FYI: Auto-generated file—review for consistency only.This file should not be manually edited per coding guidelines. Changes should be made to the async version and regenerated. The warning header is appropriate.
As per coding guidelines.
60-76: FYI: Missing noqa comment compared to async version.The async version at line 60 has
# noqa: ARG001to suppress unused argument warnings, but this sync version doesn't. Verify whether:
- The code generator intentionally omits these comments, or
- Linting is configured differently for generated files.
This is likely not an issue, but worth confirming for consistency.
27-165: LGTM: Consistent sync translation of TTL migration.The sync version correctly mirrors all changes from the async version:
- MemoryCacheEntry uses expires_at without ttl_at_insert
- from_managed_entry signature simplified
- _memory_cache_ttu uses expires_at.timestamp()
- All docstrings preserved
The auto-generation process produced consistent, correct code.

1-3: No issues found—the changes follow the correct workflow.The verification confirms that the docstring changes exist in the original async source file (
key-value/key-value-aio/src/key_value/aio/stores/simple/store.py). The sync file is auto-generated from this source and correctly reflects those changes. This is the expected, proper workflow: edits are made to the aio source, then automatically generated into the sync package during the build process.The original review comment incorrectly flagged this as a violation of the auto-generated file constraint.
Likely an incorrect or invalid review comment.

26-39: LGTM! Well-documented serialization helper.The docstring accurately describes the function's purpose and behavior. It clearly explains that this serializes a ManagedEntry to JSON with full metadata preservation for Redis storage, and properly documents the round-trip relationship with
json_to_managed_entry.
42-54: LGTM! Well-documented deserialization helper.The docstring accurately describes the function's purpose and behavior. It appropriately references the paired
managed_entry_to_jsonfunction and clearly explains that metadata is preserved during deserialization.key-value/key-value-sync/src/key_value/sync/code_gen/wrappers/limit_size/wrapper.py (2)
1-3: Correctly auto-generated file - do not edit directly.This file is auto-generated from the async version. Any functional or documentation changes should be made to the source file in
key-value/key-value-aio/src/key_value/aio/wrappers/limit_size/wrapper.py, not this generated sync version. As per coding guidelines.
102-103: LGTM: Guard prevents unnecessary calls when all entries are filtered.The guard correctly skips calling the underlying store's
put_manywhen all entries fail the size check. This optimization avoids unnecessary function overhead and prevents triggering setup or timestamp preparation when there's nothing to store.key-value/key-value-aio/src/key_value/aio/wrappers/statistics/wrapper.py (2)
83-88: Excellent documentation additions.The expanded docstrings for the aggregated statistics classes and the
get_collectionmethod are clear, well-structured, and follow Google-style format consistently. They provide valuable context for understanding the statistics hierarchy and usage patterns.Also applies to: 108-124
90-103: AI summary incorrectly claims these fields are new.The AI summary states that "ttl, put, delete, exists" fields were added to
KVStoreCollectionStatistics, but these fields already existed (lines 90-103 lack~markers indicating changes). Only the class docstring at lines 83-88 was modified in this PR.key-value/key-value-sync/src/key_value/sync/code_gen/wrappers/default_value/wrapper.py (1)
41-42: LGTM: Proper initialization chain.Adding the
super().__init__()call ensures proper initialization chain even thoughBaseWrapperdoesn't currently define__init__. This is good defensive programming and maintains consistency with other wrappers.key-value/key-value-sync/src/key_value/sync/code_gen/stores/memory/store.py (6)
28-57: LGTM: Well-documented cache entry with consistent signature.The refactor to remove
ttl_at_insertand updatefrom_managed_entryto work directly withexpires_atfromManagedEntryis cleaner and eliminates redundant TTL tracking. The documentation clearly explains the purpose and usage.
60-76: LGTM: Correct TTU calculation with clear documentation.The refactor to use
expires_atdirectly is more straightforward than the previous approach. Returningsys.maxsizefor entries without expiration correctly indicates they should never expire due to time. The docstring clearly explains the TLRUCache integration.
79-91: LGTM: Clear documentation of entry-counting strategy.The docstring effectively explains why size is always 1 (entry-based limiting rather than memory-based). This clarifies the design choice for readers.
100-165: LGTM: Comprehensive documentation for collection methods.All methods are well-documented with clear parameter descriptions and return values. The
putmethod correctly uses the updatedfrom_managed_entrysignature. Documentation follows Google-style conventions consistently.
218-234: LGTM: Explicit collection lifecycle management.The
_get_collection_or_raisehelper enforces that collections must be set up before use, providing a clear error message. This is better than implicit behavior and helps catch configuration errors early.
237-254: LGTM: Consistent use of collection validation.All internal methods now use
_get_collection_or_raise, ensuring consistent error handling across the store. This eliminates the risk of silent failures from missing collections.key-value/key-value-sync/src/key_value/sync/code_gen/wrappers/ttl_clamp/wrapper.py (1)
15-20: LGTM: Clearer documentation of wrapper scope.The expanded docstring explicitly clarifies that the wrapper only affects write operations, which helps users understand its behavior without examining the implementation. This is a valuable documentation improvement.
key-value/key-value-aio/src/key_value/aio/stores/memory/store.py (2)
36-49: LGTM! Simplified API correctly addresses past TTL recalculation issue.The refactored signature now takes only
managed_entryand extractsexpires_atdirectly from it. This eliminates the TTL recalculation problem flagged in the previous review, where remaining TTL wasn't properly calculated at insertion time. SinceManagedEntry.__post_init__setsexpires_atwhen created with attl, storingexpires_atdirectly ensures correct expiration timing regardless of when the entry was created versus when it was inserted.
139-146: LGTM! TTL recalculation issue fully resolved.The previous problematic code calling
value.recalculate_ttl()followed by passing a separatettlparameter has been removed. The new implementation correctly storesexpires_atdirectly viafrom_managed_entry(managed_entry=value), ensuring entries expire at the right absolute time regardless of when they were created versus inserted.key-value/key-value-sync/src/key_value/sync/code_gen/stores/base.py (2)
146-158: Docstring quality is excellent (pending relocation to async source).The
setup_collection()docstring is clear, comprehensive, and accurately describes:
- The lazy initialization pattern
- Per-collection thread-safety mechanism
- Idempotent behavior
- The relationship with the
_setup_collection()hookOnce this docstring is moved to the async source file (see earlier critical issue comment), it will be ready for documentation generation.
134-143: Do not edit the sync file—it is auto-generated.The file
key-value/key-value-sync/src/key_value/sync/code_gen/stores/base.pycontains a warning header stating it is auto-generated from the aio source bybuild_sync_library.py. Per the coding guidelines, this file must not be edited—changes will be overwritten.The seeding error handling concern you identified is valid and present in the source file (
key-value/key-value-aio/src/key_value/aio/stores/base.py), but the review must target the source aio implementation instead, not the generated sync version.Likely an incorrect or invalid review comment.
key-value/key-value-sync/src/key_value/sync/code_gen/wrappers/statistics/wrapper.py (3)
151-154: Behavior preserved; readability fine.get()/ttl() remain pass-through with correct stats updates. No issues.
Also applies to: 167-169
86-91: Review comment is accurate; issue is confirmed.The inconsistency exists:
KVStoreCollectionStatisticsdefines anexistsfield (line 105) and its docstring claims exists tracking (lines 88-89), butStatisticsWrapperdoes not overrideexists()despite overridingget,ttl,put, anddelete. The review comment correctly directs the developer to fix the source template rather than the generated file, which aligns with the coding guideline that files inkey-value/key-value-sync/are generated and should not be edited directly.
46-49: Do not edit auto-generated files directly; changes must be in the source template.This file is generated by
build_sync_library.pyand will be overwritten. Per the coding guidelines forkey-value/key-value-sync/**, edits must be made to the original source template instead.Additionally, the original concern about a missing
exists()override is unfounded—the KeyValue protocol does not define anexists()method, so no override is applicable. The docstring expansions themselves are clear and well-structured in Google style.Likely an incorrect or invalid review comment.

Consider more precise terminology for non-cache stores.
The docstring refers to "cache misses," but StatisticsWrapper can wrap any AsyncKeyValue store, not exclusively caches. The other operation statistics classes (DeleteStatistics, ExistsStatistics, TTLStatistics) avoid this terminology. Consider rephrasing for consistency.

around lines 43 to 46, the docstring uses "cache misses" which is inaccurate
because StatisticsWrapper can wrap any AsyncKeyValue store; update the wording

Minor: Clarify thread-safety claim.
The docstring states the immutable structure "ensures thread-safety," but this is slightly imprecise. Immutability prevents modification-related race conditions, which is a significant contributor to thread-safety, but doesn't guarantee complete thread-safety by itself.
Consider rewording to: "Using immutable structures prevents accidental modification of seed data after store initialization and helps ensure thread-safe access."

Fix async syntax in sync package example.
The example in the docstring uses async def and await, which is incorrect for the sync-generated package. Since this is auto-generated, the source file in the aio package needs to be updated to generate appropriate sync examples.

9-25: LGTM! Clean implementation of registry value retrieval.The function correctly handles missing keys and values by returning
None, which is appropriate for a read operation. The docstring is complete and follows Google-style conventions.
70-84: LGTM! Correct predicate implementation.The function appropriately returns a boolean indicating key existence, with proper error handling for missing keys and access errors.
122-145: LGTM! Enumeration bug fixed correctly.The function now correctly:
- Enumerates at index 0 repeatedly (since keys shift after deletion)
- Terminates when
EnumKeyraisesOSError(no more subkeys)- Documents non-recursive behavior clearly
The use of
contextlib.suppressfor individual deletions is appropriate for a cleanup function where partial failures should not halt the operation.Note: This function only deletes immediate children. If nested subkey deletion is needed, callers must recursively invoke this function or use a different approach.

Inconsistent error handling: some functions raise exceptions, others return bool.
The module uses mixed error-handling strategies: set_reg_sz_value and create_key raise StoreSetupError on failure, while delete_reg_sz_value and delete_key return bool. Per the PR objectives, the guidance was to "adjust Windows Registry utilities to raise store-specific exceptions instead of returning true/false for error handling."
Consider standardizing the error handling approach across all write operations (set, create, delete) to either:
- Raise
StoreSetupErrorfor all write failures (recommended for consistency with currentset_reg_sz_valueandcreate_key), or - Return
boolfor all operations and handle errors at a higher level.
As per PR objectives.

around lines 28 to 48, the module mixes exception-raising and boolean-return
error handling; update delete_reg_sz_value and delete_key to follow the existing
pattern used by set_reg_sz_value and create_key by raising StoreSetupError on
failures instead of returning False. Change the functions to attempt the
registry operation in a try block, catch FileNotFoundError/OSError (or broad
OSError) and raise StoreSetupError with a descriptive message and the original
exception as the cause (using "from e"), update docstrings to reflect they raise
StoreSetupError on failure, and have successful execution return None (no
boolean).

key-value/key-value-aio/src/key_value/aio/stores/memory/store.py (9)
24-34: LGTM: Clean dataclass structure with clear documentation.The simplified structure storing only
json_strandexpires_atis cleaner than the previous approach. The docstring clearly explains the purpose.
36-49: Signature change resolves TTL recalculation issue.The removal of the
ttlparameter and direct use ofmanaged_entry.expires_atcorrectly addresses the past review concern about TTL recalculation. Using an absolute expiration timestamp eliminates the need to recalculate remaining TTL at insertion time.
51-57: LGTM: Clear docstring for conversion method.The docstring accurately documents the method's behavior.
79-91: LGTM: Well-documented size function.The docstring clearly explains why this returns 1 (for entry counting rather than memory usage), which is helpful for understanding the cache behavior.
100-106: LGTM: Clear class documentation.The docstring effectively explains the dual nature of the cache (TTL-based expiration + LRU eviction on size limit).
121-138: LGTM: Accurate docstring relying on TLRUCache expiration.The docstring correctly states "not expired" in the return documentation, which is accurate since TLRUCache automatically handles expiration based on the
ttufunction.
139-146: LGTM: Correctly addresses past TTL issue.The updated implementation removes the problematic TTL recalculation and directly uses the
expires_atfrom theManagedEntry. This resolves the issue mentioned in past reviews where TTL wasn't being recalculated correctly.
148-157: LGTM: Clear documentation of delete behavior.The docstring accurately documents the boolean return value indicating whether the key existed.
159-169: LGTM: Well-documented keys enumeration.The docstring clearly explains the limit parameter and default behavior. The implementation correctly enforces the limit.
key-value/key-value-sync/src/key_value/sync/code_gen/stores/memory/store.py (4)
28-57: LGTM: Clean API simplification and comprehensive docstrings.The changes improve the API by:
- Removing the
ttlparameter fromfrom_managed_entry()sinceManagedEntryalready manages TTL/expiration internally- Storing
expires_atseparately fromjson_strfor efficient TTL checks without JSON deserialization- Adding clear, Google-style docstrings that explain the purpose and behavior
The redundant storage of
expires_at(both in the serialized JSON and as a separate field) is a reasonable performance optimization for_memory_cache_ttu.
60-91: LGTM: Clean TTL implementation with excellent documentation.The refactored
_memory_cache_ttuimplementation is more straightforward:
- Directly uses
expires_atinstead of calculating from stored TTL- Returns
sys.maxsizefor entries without expiration (won't be evicted by time)- Returns epoch timestamp for TLRUCache integration
The docstrings clearly explain:
- How these functions integrate with TLRUCache
- Why
_memory_cache_getsizeofalways returns 1 (entry counting vs memory measurement)- That unused parameters are intentional for TLRUCache callback signatures
100-165: LGTM: Comprehensive documentation for MemoryCollection.The added docstrings provide excellent coverage:
- Class docstring explains the TTL-based expiration and size-limited LRU behavior
- Method docstrings clearly describe parameters, return values, and behavior
- All follow Google-style conventions consistently
The
put()implementation correctly uses the simplifiedfrom_managed_entry()call without thettlparameter, aligning with the API changes.
1-3: Now let me verify the actual file contents to ensure proper generation:Based on my verification, the git history shows the proper workflow was followed. The Psycopg 3 async to sync conversion script "adds a useful disclaimer to the top of the file" matching the header in this file. The commits show:
6a9455f: "Refactor MemoryCacheEntry to use expires_at instead of ttl_at_insert" (aio changes)e733fba: "Run sync code-gen" (regeneration from aio source)a694fe8: "Run codegen" (final generation step)The presence of
build_sync_library.pyand the sequential commits confirm this sync file was properly auto-generated from the aio source, not manually edited.File is properly auto-generated; no manual edits detected.
The sync file was regenerated correctly via
build_sync_library.pyfollowing changes to the aio source. The auto-generation warning header and git history confirm the proper workflow was followed. No action needed.

🧹 Nitpick | 🔵 Trivial
Consider adding noqa comment for consistency.
The function logic correctly uses expires_at.timestamp() for expiration. Both _key and _now parameters are properly prefixed with underscores to indicate they're unused.
For consistency with line 79 (which has # noqa: ARG001), consider adding # noqa: ARG001, ARG003 to suppress linting warnings for both unused parameters, though this is a minor style point.
Based on past review comments.
