128-158: LGTM! Consider adding documentation comments.The
RefKeysmethod is well-implemented and handles both unique and non-unique scenarios effectively. The sanity check is a good practice to prevent misuse of the method.To improve the usability of the method, consider adding documentation comments to explain its usage and behavior. For example:
// RefKeys returns a list of all the MultiIterator's reference keys. // If the "unique" argument is enabled, it returns a unique list of reference keys. // Note: The reference key type must be comparable when using the "unique" option. func (m *Multi[ReferenceKey, PrimaryKey, Value]) RefKeys(ctx context.Context, unique bool) ([]ReferenceKey, error) { // ... }

113-113: Verify the purpose and impact of the additional parameter inNewPrefixedTripleRange.The change introduces an additional boolean parameter
falseto theNewPrefixedTripleRangefunction when calling theClearmethod ofValidatorSlashEvents. This suggests a refinement in how validator slash events are managed and could influence the outcome of theClearoperation.To ensure that the change aligns with the intended behavior, please verify the following:
- What is the purpose of the additional boolean parameter in
NewPrefixedTripleRange?- How does this parameter affect the behavior of the range being cleared?
- Confirm that the change produces the desired outcome in terms of managing validator slash events.
You can use the following script to analyze the usage of
NewPrefixedTripleRangeand its impact on theClearoperation:Examining the results will provide insights into how the additional parameter is used and its effect on the clearing of validator slash events.
Verification successful
The additional boolean parameter in
NewPrefixedTripleRangedetermines the order of the range.The boolean parameter added to
NewPrefixedTripleRangespecifies the order in which the range is processed:falsefor ascending andtruefor descending. In the context ofValidatorSlashEvents.Clear, setting this parameter tofalseensures that the slash events are cleared in ascending order. This change likely aligns with the intended behavior if the order of clearing is crucial for the operation's logic. Please verify that this order is necessary for maintaining consistency or correctness in managing validator slash events.

1169-1169: Verify the impact of the boolean parameter on iteration behavior.The addition of a boolean parameter to the
NewPrefixedTripleRangefunction, as indicated by the AI-generated summary, suggests a change in how ranges are created and potentially how iteration is handled. It's crucial to ensure that this change does not adversely affect existing functionality or expected behavior in iteration processes.Verification successful
The boolean parameter in
NewPrefixedTripleRangeis well-tested and does not adversely affect iteration behavior.The
NewPrefixedTripleRangefunction's boolean parameter is used to control the order of iteration, and its impact is verified through test cases that cover both ascending and descending orders. This ensures that the function behaves as expected without affecting existing functionality.

Can we not break the API, please? We strive to have more stable APIs.
Additionally, I am super a fan of just having a bool in the function.
Can create new APIs instead? Like NewPrefixUntilTripleRangeReversed or something alike.
There was a problem hiding this comment.
Sure.
I thought maybe turn it to a variadic function so the reverse bool will be optional. By doing that, the API won't break but will be able to support reverse iteration.
Your solution obviously works too, but it add 3 functions that are basically the same code but with the "order" field set to reverse which is a sort of code duplication.
What approach should I take?

Adding options would work too yes 👍🏾.

i think we should RawIterate getting bytes, then use the bytes as map index. (can be efficiently done with unsafe)
then convert them to the real type later using the key codec
There was a problem hiding this comment.
not sure I follow. IterateRaw uses an untyped range but returns a typed iterator. So we're not getting bytes out of it. Can you write a small pseudo code of what you meant? (or explain in other words?) @testinginprod

The work is almost done, I would really like see this code merged, and it's stuck for some time (@julienrbrt)

Sorry for being slow!
So:
- we cannot use reflection.
- we should iterate the map using the raw bytes and comparing the raw bytes for equality
There was a problem hiding this comment.
Also maybe to fast track merging, we could split the PR in two,and push the multi refkeys method to another PR since it is more contentious than the triple reverse range

now comparing bytes for equality and not using reflect :) @testinginprod

this will not work on keys different from string/bytes
There was a problem hiding this comment.
I am now converting the Multi key codec to be a pairKeyCodec so I can directly get the reference key codec and use it to encode to bytes (instead of using the unsafe package).
It must work since the Multi KeyCodec is a key codec of a Pair: ReferenceKey and PrimaryKey. I manually tried my new implementation with uint64 ref keys and it worked.

124-128: Consider enhancing the method documentationThe warning about gas costs is crucial information. Consider expanding on this to provide more specific guidance to users.
You could add:
- An estimate of what constitutes a "small set" of reference keys.
- Suggestions for alternative approaches when dealing with large sets.
- A note on the time complexity of the operation.
This additional information would help developers make informed decisions about using this method.

136-141: LGTM: Proper iteration and error handlingThe iteration over keys and error handling for
iter.Key()are implemented correctly. Good job on ensuring robust error handling throughout the loop.
160-164: LGTM: Proper key collection and returnThe final part of the method, including the collection of keys and the return statement, is implemented correctly.
124-164: Overall assessment: Well-implemented with room for optimizationThe
RefKeysmethod is generally well-implemented and follows Go best practices. It correctly handles the retrieval of reference keys with an option for uniqueness. The error handling is robust, and the logic is sound.However, there are opportunities for optimization, especially when dealing with large sets of keys:
- Pre-allocating the slice and map
- Reusing the buffer for key encoding
These optimizations could potentially improve performance and reduce memory allocations.
Consider implementing these optimizations and conducting benchmarks to measure the performance impact, especially for large sets of keys.
To verify the performance impact of the suggested optimizations, you could run the following benchmark:
This will help quantify the performance improvements and ensure that the optimizations are effective.
Description
Closes: #21091
Added the
RefKeys()method for theMultitype to get a full list of the existing reference keys (with option for unique list). Also, added missing support of reverse iterator for aTriplecollection (always usedorder=OrderAscendingwithout option to edit).Author Checklist
