Bazel 6.3.0 is a minor LTS release. It is fully backward compatible with Bazel 6.0 and contains selected changes by the Bazel community and Google engineers.

Highlights

  • The new bazel mod command allows users to inspect their external dependency graph in Bzlmod. See documentation for details.
  • Full lockfile support has been added to Bzlmod and is now enabled by default. See documentation for details.

General

  • Options specified on the pseudo-command common in .rc files are now ignored by commands that do not support them as long as they are valid options for any Bazel command. Previously, commands that did not support all options given for common would fail to run. These previous semantics of common are now available via the new always pseudo-command. (#18609)
  • Improve error on invalid -//foo and -@repo//foo options (#18516)
  • Adjust --top_level_targets_for_symlinks: bazel-bin, bazel-testlogs, etc. no longer mysteriously disappear (#18916)
  • Fix Xcode 14.3 compatibility (#18490)
  • Remove option to disable ForkJoinPool. (#18791)

Android

  • Fix D8 dex merger failure when a synthetic class is placed on a different shard than its container class (#16368)
  • Add a new provider for injecting native libs in android_binary for android_binary Starlarkification (#18753)
  • Add a new provider for passing dex related artifacts in android_binary for android_binary Starlarkification (#18899)

Build Event Protocol

  • Add ActionCacheStatistics to BEP (#18914)

C++ / Objective-C

  • Make cpp file extensions case sensitive again (#18552)
  • Add changes to cc_shared_library from head to 6.3 (#18606)

  • Add implementation deps support for Objective-C (#18372)
  • Add external_include_paths feature on Windows toolchain (#18654)
  • Additional source inputs can now be specified for compilation in cc_library targets using the additional_compiler_inputs attribute, and these inputs can be used in the $(location) function. (#18882)
  • Fix VS 2022 autodetection (#18960)

Coverage

  • Expose metadata_files parameter in coverage_common.instrumented_files_info (#18838)
  • Check if json.gz files exist, not the gcov version. (#18889)
  • Add flag --experimental_collect_code_coverage_for_generated_files to enable coverage collection for generated files. (#18664)
  • Fix split post-processing of LLVM-based coverage (#18737)

External Dependencies / Bzlmod

  • Overrides specified by non-root modules no longer cause an error, and are silently ignored instead. (#18388)
  • The --credential_helper flag is now stable, and works for repo fetching.
  • Module extension usages can now be specified to be isolated. Each isolated usage causes a separate evaluation of the extension. See documentation for more details.
  • Report percentual download progress in repository rules (#18471)
  • Ignore hash string casing (#18414)
  • Include actual MODULE.bazel location in stack traces (#18612)
  • Fix WORKSPACE toolchain resolution with --enable_bzlmod (#18649)
  • The REPO.bazel and MODULE.bazel files are now also considered as workspace boundary markers. (#18787)
  • Yanked module versions no longer contribute dependency requirements or emit DEBUG messages for print() statements (#18908)
  • Report dev/non-dev deps imported via non-dev/dev usages (#18922)
  • Identify isolated extensions by exported name (#18923)

Java

  • Pass version to java_runtimes created by local_java_repository (#18415)
  • Teach ijar about dynamic constants (#18729)
  • Update to latest turbine version (#18803)
  • Update Error Prone to 2.20.0 (#18885)
  • Update java_tools to v12.5 (#18868)
  • Disable UseCorrectAssertInTests by default (#18948)

Local Execution

  • Use local_termination_grace_seconds when testing LinuxSandbox availability (#18568)

Query

  • Add jsonproto option to query --output flag (#18438)
  • query --output=proto --order_output=deps now returns targets in topological order (previously there was no ordering). (#18870)

Remote Execution

  • Prevent CredentialHelperEnvironment crash when invoking Bazel outside of a workspace. (#18430)
  • Use wall-time for credential helper invalidation (#18413)

  • Enrich local BEP upload errors with file path and digest possible. (#18481)
  • Extend the credential helper default timeout to 10s. (#18527)

  • Don't rewind the build if invocation id stays the same (#18670)
  • Fix potential memory leak in UI when BwoB. (#18659)
  • Properly handle invalid credential files (#18779)
  • Report remote execution messages as events (#18780)
  • Wait for outputs downloads before emitting local BEP events that reference these outputs. (#18815)

  • Download directory output for test actions (#18846)
