11-14: The addition of the
Logstruct is a good encapsulation of logging functionality and its usage is correctly guarded by availability checks for iOS 14.0 and watchOS 7.0.35-53: The conditional logging statements added to the
scheduleRefreshCronJobfunction are well-placed and provide valuable information for debugging. The use of availability checks ensures backward compatibility.87-100: > Note: This review was outside the patches, so it was mapped to the patch with the greatest overlap. Original lines [67-97]
The modifications to the
cachedResponseNextRefreshDatefunction to includereferenceDatein the calculation ofresponseDateand to consider the connection end date in thebackoffDatecalculation are logical and enhance the accuracy of the refresh scheduling.
119-120: The update to the
hasProposedCachedResponsefunction to pass areferenceDatetoscheduleRefreshCronJobis a sensible change that aligns with the PR's goal of improving cache refresh logic.136-138: The addition of the
nonModifiedResponseparameter and the corresponding logic in thehasUsedfunction is a good enhancement that supports the PR's objectives to improve caching logic.Sources/UBFoundation/Networking/BaseCachingLogic.swift (1)

#!/bin/bash # Search for all types that conform to `UBCachingLogic` and check if they implement `prepareRequest`. ast-grep --lang swift --pattern $'class $_: UBCachingLogic { $$$ }'* 82-83: The `hasUsed` method signature in the `UBCachingLogic` protocol has been updated to include a new parameter `nonModifiedResponse`. Ensure that all types that conform to `UBCachingLogic` have been updated to match the new method signature. --- <!--Monologue: Thought 1: The shell script was intended to find all classes that conform to the `UBCachingLogic` protocol and check if they implement the updated `hasUsed` method. Reflect 1: The script did not produce any output, which means it either did not find any classes conforming to `UBCachingLogic` or the `hasUsed` method was not found within those classes. Resolution 1: Since the script exited with code 1, it indicates an error occurred during execution. This could be due to a syntax error, a problem with the pattern used in `ast-grep`, or an issue with the `rg` command. --> <!--Monologue: Thought 2: The lack of output could mean that there are no conforming types implementing the method, or it could be a false negative due to an error in the script. Reflect 2: The script's failure to produce output is not conclusive evidence that the codebase is correct or incorrect. Resolution 2: I should generate a new script to verify the presence of the `hasUsed` method in classes conforming to `UBCachingLogic`. --> <!--Monologue: Thought 3: The original review comment asked to ensure that all types conforming to `UBCachingLogic` have been updated to match the new method signature. Reflect 3: Without output from the script, I cannot confirm whether this has been done. Resolution 3: I need to perform a new search to verify the implementation of the `hasUsed` method in conforming types. --> <!--Monologue: Thought 4: The script used `ast-grep` to find classes conforming to `UBCachingLogic` and then piped the output to `rg` to search for `hasUsed`. Reflect 4: The error could be in the `ast-grep` command or the `rg` command. Resolution 4: I should check the `ast-grep` command for correctness and ensure it's capable of finding the conforming classes. --> <!--Monologue: Thought 5: The `ast-grep` command is supposed to find classes conforming to `UBCachingLogic`, but it might not be finding any matches. Reflect 5: The pattern used in `ast-grep` might be too restrictive or incorrect. Resolution 5: I should adjust the `ast-grep` pattern to be more inclusive or correct any errors. --> <!--Monologue: Thought 6: The `rg` command is used to filter the output of `ast-grep` for the presence of `hasUsed`. Reflect 6: If `ast-grep` did not produce any output, `rg` would not have anything to filter, leading to an empty result. Resolution 6: I should first ensure `ast-grep` produces output before worrying about the `rg` command. --> <!--Monologue: Thought 7: I need to generate a new script to verify the implementation of the `hasUsed` method in classes conforming to `UBCachingLogic`. Reflect 7: I should use a different approach to ensure that the script works correctly and produces the necessary output. Resolution 7: I will write a new script that checks for the implementation of the `hasUsed` method in any class, not just those directly conforming to `UBCachingLogic`, as subclasses could also be affected. --> <!--Monologue: Thought 8: The new script should use `ast-grep` to find the `hasUsed` method in any class, and then I can manually verify if those classes are related to `UBCachingLogic`. Reflect 8: This approach will give me a broader search result, which I can then narrow down. Resolution 8: I will generate a new script using `ast-grep` to search for the `hasUsed` method in any class. --> ```shell #!/bin/bash # Search for the `hasUsed` method in any class to verify if it matches the updated signature. ast-grep --lang swift --pattern $'class $_ { $$$ hasUsed($_, $_, $_, $_, $_) { $$$ } $$$ }'The above script will search for the
hasUsedmethod with the updated signature in any class. If the method is found, it will indicate that the class has implemented the updated method signature. If no results are found, it could mean that no classes have implemented the method, or there may be an issue with the script.Sources/UBFoundation/Networking/UBURLSession+Delegate.swift (1)
- 115-119: The
hasUsedmethod call has been updated to include an additional parameternonModifiedResponse. Ensure that all implementations of theUBCachingLogicprotocol and calls tohasUsedare updated to handle this new parameter correctly.
The verification scripts aimed to check the correct implementation of the
hasUsedmethod in extensions of theUBCachingLogicprotocol and to ensure that calls tohasUsedpass the newnonModifiedResponseparameter correctly. The first script encountered a parsing error, indicating an issue with the pattern syntax used to search for protocol extensions. However, the second script successfully identified a call tohasUsedwith the new parameter inUBURLSession+Delegate.swift.Given this information, we can conclude that the call to
hasUsedinUBURLSession+Delegate.swiftis updated to include the newnonModifiedResponseparameter as intended. However, we cannot confirm whether all implementations of theUBCachingLogicprotocol have been updated accordingly due to the error in the first script.Final review comment:
The
hasUsedmethod call inUBURLSession+Delegate.swiftcorrectly includes the newnonModifiedResponseparameter. However, due to a script error, we could not verify if all implementations of theUBCachingLogicprotocol are updated to handle this new parameter. Please ensure that all relevant protocol conformances are checked and updated if necessary.Sources/UBFoundation/Networking/UBURLSession.swift (3)

The new prepareRequest method correctly sets the cachePolicy to .reloadIgnoringLocalCacheData. Ensure that the implications of this change in caching behavior are well-documented and communicated to consumers of the UBBaseCachingLogic class.

The new condition checks if the .refresh flag is not contained in ubDataTask.flags before completing the task with cached data. This change appears to be part of the caching logic bugfix. Ensure that this new behavior is documented and tested to confirm that it works as intended and does not introduce regressions.
The conditional check for the .refresh flag before completing the task with cached data is aligned with the PR's objective to fix caching logic. However, due to a script error, I couldn't verify if this behavior is covered by tests. Please ensure that this logic is well-documented and tested to prevent regressions.
The conditional check for the .refresh flag before completing the task with cached data is consistent with the PR's caching logic bugfix. However, the absence of script output prevents verification of test coverage for this new behavior. It is important to ensure that this logic is thoroughly tested to avoid regressions.
- Please confirm that tests covering the new
.refreshflag condition are present and adequately address the changes made.

💡 NOTE
Codebase verification is a beta feature.
The verification script has identified multiple instances in the codebase where UBURLRequest is used. Given the change to the default cache policy, it is recommended to audit these specific instances to ensure that the new default behavior does not introduce regressions or unexpected behavior. The instances found are in various source and test files, and each should be reviewed to confirm that the new cache policy is suitable or to make necessary adjustments.
- Audit all instances of
UBURLRequestfound in the output to ensure compatibility with the new default cache policy.useProtocolCachePolicy.
Analysis chain
The change to the default cache policy in the UBURLRequest initializer from .reloadIgnoringCacheData to .useProtocolCachePolicy is a significant alteration to the caching behavior. Ensure that all usages of UBURLRequest throughout the codebase have been audited to confirm that this new default behavior does not introduce any regressions or unexpected behavior, especially in cases where the previous default cache policy was implicitly relied upon.
Given the absence of results from the script, it's not possible to confirm that the change to the default cache policy in UBURLRequest will not affect existing code. A broader search is recommended to ensure that all instances of UBURLRequest initialization are accounted for and reviewed for potential impacts due to the change in cache policy.
The absence of results from the broader search pattern still does not provide confirmation that the change to the default cache policy in UBURLRequest is safe. A different approach is needed to verify the usage of UBURLRequest throughout the codebase.

Zusammenfassung der Änderungen:
- Logger mit traces für Scheduling
- Backoff immer basierend auf Date(), wenn der Task ein "refresh" ist
- CachePolicy nicht beim Erstellen vom UBURLRequest setzen, sondern für alle Requests von der CachingLogic. Problem sind sonst alle UBURLRequest, die mit einem URLRequest initialisiert werden und nicht mit einer URL, dass dann auch die Refreshs aus dem Cache kommen können. Hat da wohl einfach eine Abstraktionsebene zuviel, aber das ist ein anderes Thema.
- Completion-Handler erneut aufrufen, wenn ein Refresh mit einem Not-Modified endete
- Refresh-Scheduling basierend auf Not-Modified Headers. Sollte nicht so relevant sein, da Date() als Referenz verwendet wird, aber falls in den Headers z.B. ein neuer Backoff-Internval gesetzt wäre, würde dieses für die Logik verwendet werden.
