Walkthrough

The changes involve modifications to rule definitions and permission logic across multiple files. Key alterations include simplifying the parameters of rules such as check_region and check_ip_range, which now rely solely on context data instead of external inputs. Additionally, permission checks for various entities have been updated to directly reference context attributes, enhancing the overall structure and consistency of the access control logic.

Changes

Files Change Summary
assets/example-shapes/disney-plus.yaml Modified check_region rule to remove region parameter, retaining only allowed_region.
docs/getting-started/modeling.mdx Updated view permission to reference ip_range directly; modified check_ip_range rule to remove ip parameter, retaining only ip_range.
docs/use-cases/abac.mdx Refactored permission checks for view, withdraw, and delete to use context attributes; simplified rule definitions for check_ip_range, check_location, and check_age. Modified is_weekday rule to accept a list of valid weekdays.
internal/engines/entityFilter.go Added a check for entrances being nil in EntityFilter method; modified parameters passed to engine.lt method.

69-71: LGTM!

The check for nil entrances is a valid optimization to prevent unnecessary processing when there are no linked entrances. Returning nil aligns with the function's return type.


90-90: Verify the impact of the context change.

The change from ctx to cont suggests a shift in the context being used for the execution of the lt method. Please ensure that this change does not introduce any unintended side effects or alter the expected behavior of the lt method.

Verification successful

Context change appears consistent with codebase usage

The change from ctx to cont in the engine.lt call is consistent with the usage of cont throughout the internal/engines/entityFilter.go file. The cont context is initialized using errgroup.WithContext(cctx) and is used consistently in various method calls within this file, including relationEntrance, attributeEntrance, and tupleToUserSetEntrance. This pattern aligns with the usage of cont in other parts of the codebase, such as in pkg/development/development.go and pkg/cmd/validate.go.

Scripts executed

The following scripts were executed for the analysis:

Script:

#!/bin/bash
# Description: Verify the usage of the `cont` context in the `lt` method.

# Test: Search for the declaration and usage of the `cont` context. 
# Expect: The `cont` context should be properly initialized and used consistently.
rg --type go $'cont :=|cont,'

48-50: Verify the rule invocations are updated to match the new signature.

The rule signature and body changes look good. The updated rule signature is simpler and more consistent with the rule body, which directly accesses the context's region data.

However, please ensure that all invocations of the check_region rule are updated to remove the region argument, as this is a breaking change.

Run the following script to verify the rule usage:

Verification successful

Rule invocations correctly updated to match the new signature

The verification process confirms that all occurrences of the check_region rule in the codebase are consistent with the new signature. The rule is correctly defined with a single allowed_region parameter, and its usage in the action view definition also matches this updated signature.

No further actions are required regarding the check_region rule update.

Scripts executed

The following scripts were executed for the analysis:

Script:

#!/bin/bash
# Description: Verify all invocations of the `check_region` rule match the new signature.

# Test: Search for the rule usage. Expect: Only occurrences of the new signature.

90-94: LGTM!

The changes simplify the permission definition by directly referencing the ip_range attribute in the check_ip_range rule. The overall permission logic remains the same.


137-141: LGTM!

The changes simplify the permission definition by directly referencing the location attribute in the check_location rule. Using the current_location from the context data ensures consistency in how the location is determined.


161-167: LGTM!

The changes simplify the permission definition by directly referencing the min_age attribute in the check_age rule. Using the age from the context data ensures consistency in how the age is determined.


188-192: LGTM!

The changes simplify the permission definition by directly referencing the balance attribute in the check_balance rule. Using the amount from the context data ensures consistency in how the withdrawal amount is determined.


Line range hint 253-266: LGTM!

The changes simplify the permission definition by directly referencing the valid_weekdays attribute in the is_weekday rule. Using the day_of_week from the context data ensures consistency in how the day is determined. The valid_weekdays attribute allows for flexibility in defining valid days for each organization.


277-282: LGTM!

The request keys for the organization.view permission check are consistent with the changes made to the is_weekday rule and the view permission. The keys correctly reference the valid_weekdays attribute and the member relation.


299-303: Skipped

This code segment is a duplicate of the previous one. No further comments are necessary.


321-326: LGTM!

The request keys for the account.withdraw permission check are consistent with the changes made to the check_balance rule and the withdraw permission. The keys correctly reference the balance attribute and the owner relation.


402-406: Skipped

This code segment is a duplicate of the previous one. No further comments are necessary.


418-418: LGTM!

The example context data includes the relevant attributes (ip_address and day_of_week) used in the permission rules. This allows for flexibility in defining the necessary context for each permission check.


536-539: More context needed

The code snippet defines a delete permission that relies on the is_weekday rule and the valid_weekdays attribute. However, the complete context of the entity and the valid_weekdays attribute definition is missing. Please provide the surrounding code for a more comprehensive review.
[incomplete_context]


561-565: LGTM!

The attribute and permission definitions for the repository entity are well-structured and provide appropriate access control:

  • The is_public attribute determines public visibility of the repository.
  • The edit permission maintains consistency with the related organization's view permission.
  • The delete permission utilizes the is_weekday rule with the valid_weekdays attribute to restrict deletion to specific

Tip

Codebase Verification

Update test files and documentation for consistency with check_ip_range changes

The simplification of the check_ip_range function has been successfully implemented in most of the codebase. However, there are some inconsistencies that need to be addressed:

  1. Test files still use the old signature:

    • internal/storage/memory/schemaReader_test.go
    • internal/storage/postgres/schemaReader_test.go
  2. Mixed usage in documentation:

    • docs/use-cases/abac.mdx contains both old and new signatures

To ensure consistency and prevent potential errors, please:

  • Update the test files to use the new check_ip_range signature with a single parameter.
  • Revise docs/use-cases/abac.mdx to consistently use the new signature throughout the document.

These changes will align all parts of the codebase with the simplified check_ip_range implementation.

Analysis chain

Simplification of the view permission logic looks good!

The change leverages the context data directly for the IP address, simplifying the permission check.

Please ensure the following:

  1. Verify that the IP address is consistently available in the context data.
  2. Run the following script to identify and update any remaining invocations of check_ip_range with the old signature:

Tip

Codebase Verification

Inconsistent usage of check_ip_range detected across the codebase

The verification process has revealed that the check_ip_range function is not consistently updated throughout the codebase. While some instances use the new single-parameter signature, others still use the old two-parameter version. This inconsistency needs to be addressed to ensure proper functionality and maintain code coherence.

Please update the following:

  1. Test files:
    • internal/storage/postgres/schemaReader_test.go
    • internal/storage/memory/schemaReader_test.go
  2. Documentation:
    • docs/use-cases/abac.mdx

When updating these files, ensure that:

  • The function signature is changed to check_ip_range(ip_range string[]).
  • Any calls to check_ip_range are updated to use only the ip_range parameter.
  • The function body uses context.data.ip instead of a passed ip parameter.

After making these changes, thoroughly test the affected components to ensure no functionality is broken.

Analysis chain

Encapsulation enhancement of the check_ip_range rule looks good!

The rule now directly leverages the context data for the IP address, enhancing encapsulation and simplifying the logic.

Please ensure the following:

  1. Verify that the IP address is consistently available under context.data.ip.
  2. Run the following script to identify and update any remaining invocations of check_ip_range with the old signature:
