:bazel-diff -- generate-hashes is not giving correct targets when changed something in build attribute .bzl file which imported in many BUILD files

Hi,

I am using bazel run :bazel-diff -- generate-hashes --workspacePath="/home/jenkins/workspace/PROJECT" /home/jenkins/starting_hashes1.json against a commit id to find out list of files and similarly running the same command to find the final_hashes.json file against a final commit after checking out the code git checkout "c41b43xxxxxxxxxx"

But i observed this is not returning correct targets when i run

bazel run :bazel-diff -- get-impacted-targets --startingHashes=/home/jenkins/starting_hashes.json --finalHashes=/home/jenkins/final_hashes.json --output=/home/jenkins/bazel_diff_impacted_targets.json

However i tried using --useCquery="true" while generating hashes hope it might give me correct file list but it is damn slow .

I am using bazel 7.3 .

Please suggest if anything can be done or missing?

Regards, abcuser

Can you get me an explanation of what you mean by not the correct targets, what targets are missing from your impacted list?

Also a minor repro story can help in debugging this since this should likely be a CI check in the repo to make sure we don't regress on whatever the issue is here

Let's say i have defined service metadata to something called all_gke_service.bzl

`def all_gke_service( name, acceptance_test_tags = ["acceptance"], technology_type = "java", upload_to_nexus_targets = [], unit_test_tags = ["unit"], **kwargs): """Generates GKE deployment configs for each service

Args:
  name: service name (without tenant suffix)
  acceptance_test_tags: tag(s) for acceptance tests for the main service
  technology_type: the type of technology in which the service was written
  upload_to_nexus_targets: list of Nexus upload targets, if any
  unit_test_tags: tag(s) for unit tests for the main service
  **kwargs: any other service attributes that apply to all tenants (pass-through)
"""

arguments = struct(
    name = name,
    acceptance_test_tags = acceptance_test_tags,
    technology_type = technology_type,
    upload_to_nexus_targets = upload_to_nexus_targets,
    unit_test_tags = unit_test_tags,
    subdir_prefix = subdir_prefix,
)

# Validate required attributes
validate_common_arguments(arguments)`

Then i am using all_gke_service.bzl file in some application BUILD.bazel file. like

`load("//bazel:mvn_rules.bzl", "mvn_install") load("//bazel:all_gke_service.bzl", "all_gke_service")

package(default_visibility = ["//visibility:public"])

test_suite( name = "all_tests", )

mvn_install( name = "service", srcs = [":main_srcs"], finalName = "app-service.jar", java_version = "java-17-openjdk", project = "service", deps = [ ], )

all_gke_service( name = "test-service", acceptance_test_tags = [], # disabled until acceptance test functionality is fixed .... .... ) `

SO when i change anything in all_gke_service.bzl , i am expecting bazel-diff get-impacted-targets should return all service targets which uses all_gke_service.bzl in their BUILD.bazel file but bazel-diff get-impacted-targets command wont return any thing
