Hello @arvi18, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
Summary of Changes
This pull request introduces a new flag, --allowed_strategies_by_exec_platform, to filter spawn strategies based on the execution platform. This is part of the implementation for the Execution Platform Scoped Spawn Strategies proposal. The changes modify how spawn strategies are resolved, incorporating the new flag to allow or disallow certain strategies for specific execution platforms. The goal is to provide more fine-grained control over where actions are executed, for example, preventing remote execution for host platform actions.
Highlights
- New Flag: Introduces the
--allowed_strategies_by_exec_platformflag to filter spawn strategies based on the execution platform. - Strategy Filtering: Implements filtering logic within the
SpawnStrategyRegistryto consider the allowed strategies for a given execution platform. - Error Reporting: Updates the error message when no valid spawn strategies are available after filtering, indicating the potential impact of the new flag.
- Remote Fallback: Modifies the
RemoteLocalFallbackRegistryto consider the execution platform when selecting a fallback strategy.

Code Review
This pull request introduces a new flag --allowed_strategies_by_exec_platform to filter spawn strategies based on the execution platform. The implementation involves adding a new filter StrategyPlatformFilter to the SpawnStrategyRegistry and updating the logic to retrieve spawn strategies. The changes seem well-structured and the provided examples are helpful. However, there are a few areas that could be improved, such as adding a null check for platformLabel and improving the error message in the Preconditions.checkNotNull call.
Summary of Findings
- Missing null check: The code directly dereferences
platformLabelwithout checking if it's null, which could lead to aNullPointerException. A null check should be added before accessingplatformLabel. - Preconditions check message: The message in the
Preconditions.checkNotNullcall inStrategyPlatformFilteris not very informative. It should be updated to provide more context about why the execution platform is required. - Inconsistent use of var: The code uses
varin some places and explicit types in others. It would be more consistent to use eithervaror explicit types throughout the code. - Logging level: The log messages in
SpawnStrategyRegistryare at the INFO level, which might be too verbose. Consider using a more appropriate logging level, such as DEBUG.
Merge Readiness
The pull request is not ready for merging. There are a few issues that need to be addressed before merging, such as adding a null check for platformLabel and improving the error message in the Preconditions.checkNotNull call. I am unable to directly approve this pull request, and users should have others review and approve this code before merging.

125-141: Help text and converter mismatch can confuse users
allowed_strategies_by_exec_platformis declared withStringToStringListConverter, which expects key=value1,value2 syntax, but the help text shows multi-line examples and back-ticks.
Two small issues:
- Consistency – every other flag uses a regular string, not a text-block. Sticking to one style avoids noise in
--help.- Ambiguity – mention explicitly that the option can be repeated and that the right-hand side is comma-separated.
No code breakage, just documentation polish.

allowedStrategies.contains(strategy)is O(n) over anImmutableList.

src/test/java/com/google/devtools/build/lib/exec/util/FakeOwner.java (1)
82-88: Improved platform safety by replacing null with EMPTY_PLATFORM_INFOThis change ensures consistency with the broader execution platform-aware filtering being implemented. By explicitly providing
PlatformInfo.EMPTY_PLATFORM_INFOinstead of implicitly passingnull, the code prevents potential NullPointerExceptions and aligns with the execution platform-based spawn strategy filtering introduced in this PR.src/main/java/com/google/devtools/build/lib/exec/RemoteLocalFallbackRegistry.java (1)
17-18: Updated interface to support platform-specific strategy selectionThe method signature change for
getRemoteLocalFallbackStrategynow includes aSpawnparameter, allowing fallback strategies to be selected based on execution platform information associated with each spawn. This change properly aligns with the new execution platform-based strategy filtering functionality.Also applies to: 32-33
src/main/java/com/google/devtools/build/lib/exec/BUILD (2)
107-110: Added dependency for new options functionalityAdding the
config/fragment_optionsdependency to theexecution_optionstarget supports the new command-line option--allowed_strategies_by_exec_platformthat filters spawn strategies by execution platform.
367-369: Added dependency for command-line handlingAdding the
cmdlinedependency to thespawn_strategy_registrytarget enables parsing and handling of new command-line options for execution platform-specific strategy filtering.src/test/java/com/google/devtools/build/lib/exec/BUILD (1)
47-49: Added platform dependency for testing execution platform filteringAdding the
analysis/platformdependency enables tests to properly validate the new execution platform-based strategy filtering functionality.src/main/java/com/google/devtools/build/lib/exec/SpawnStrategyResolver.java (1)
89-94: Clean error message update with new flag information.The error message was updated to include the new
--allowed_strategies_by_exec_platformflag, which is consistent with the PR objective of implementing platform-scoped spawn strategies. Using a text block (triple quotes) also improves readability of the code.src/main/java/com/google/devtools/build/lib/bazel/rules/BazelStrategyModule.java (1)
21-21: LGTM - Necessary import added.Added import for Label class which is needed for the new platform filtering functionality.
src/main/java/com/google/devtools/build/lib/remote/RemoteSpawnRunner.java (1)
558-558: Updated method call to pass spawn parameter.The method call is correctly updated to pass the spawn instance to the
getRemoteLocalFallbackStrategymethod, aligning with the new API that enables platform-aware fallback strategy selection.src/test/java/com/google/devtools/build/lib/remote/RemoteSpawnRunnerTest.java (1)
267-267: Test correctly updated to match the new API.The lambda expression now accepts a Spawn parameter (
_spawn), properly matching the updated method signature inRemoteLocalFallbackRegistry. The underscore prefix is a common convention indicating the parameter is not used in the lambda body.src/main/java/com/google/devtools/build/lib/analysis/platform/PlatformUtils.java (1)
79-84: Early-return guard looks good, just double-check the cost ofremoteExecutionProperties()The additional check correctly treats execution platforms that have no
execPropertiesand noremoteExecutionPropertiesthe same as “no execution platform”.
BecauseremoteExecutionProperties()returns a (possibly large) string, consider calling it only once and caching the result in a local variable if this method ever appears on a hot path.
Otherwise the change is ✔️.src/main/java/com/google/devtools/build/lib/exec/SpawnStrategyRegistry.java (1)
174-178:⚠️ Potential issue
getRemoteLocalFallbackStrategycan NPE / require JDK-21
List#getFirst()is only available since JDK 21.
On older LTS releases (JDK 11/17) this method does not exist, causing compilation failure.It is also unsafe when
remoteLocalFallbackStrategy == nulland is filtered-out.- return strategyPlatformFilter.getStrategies( - spawn, Lists.newArrayList(remoteLocalFallbackStrategy)) - .getFirst(); + var filtered = + strategyPlatformFilter.getStrategies( + spawn, Lists.newArrayList(remoteLocalFallbackStrategy)); + return filtered.isEmpty() ? null : filtered.get(0);Likely an incorrect or invalid review comment.
src/test/java/com/google/devtools/build/lib/exec/SpawnStrategyRegistryTest.java (1)
305-321: Test may hide real-world null-platform issues
createSpawnWithMnemonicAndDescriptionproduces aSimpleSpawnwithout an execution platform, yet the test passes becausePlatformInfo.EMPTY_PLATFORM_INFOhappens to be returned.
Consider adding a second assertion with a trulynullplatform (or adapting the production code per earlier comment) to avoid a false sense of security.

Potential N+1 Performance Issue in Platform Filter Strategy Selection
The current implementation iterates through all candidate strategies for each spawn, checking if each strategy is in the allowed strategies list. This creates an O(n*m) operation where n is the number of candidate strategies and m is the number of allowed strategies. For platforms with many strategies and frequent spawns, this could create unnecessary CPU overhead. Additionally, the linear search pattern can be inefficient for large strategy collections.
var allowedStrategies = platformToStrategies.get(platformLabel);
if (allowedStrategies != null) {
// Convert to HashSet for O(1) lookups instead of O(n) contains() operations
Set<SpawnStrategy> allowedStrategiesSet = new HashSet<>(allowedStrategies);
List<T> filteredStrategies = new ArrayList<>();
for (var strategy : candidateStrategies) {
if (allowedStrategiesSet.contains(strategy)) {
filteredStrategies.add(strategy);
}
}
// If filtering resulted in an empty list, return original candidates
// to ensure at least one strategy is available
return filteredStrategies.isEmpty() ? candidateStrategies : filteredStrategies;

Null pointer risk in platform label validation
