bazelbuild/bazel 6.2.0

on GitHub

Baseline: d60ce2c

Bazel 6.2.0 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

• Added preliminary support for a lockfile for Bzlmod. It's disabled by default; use --lockfile_mode=update to enable it. Check flag documentation here. This lockfile contains only Bazel module information; it does not involve module extensions. (#18143)

General

• @foo labels can now be used on the command line as the top-level target (that is, bazel build @foo now works). Double-dot syntax is now forbidden (bazel build ../foo will no longer work). (#17945)
• The aquery and cquery commands now respect the --query_file flag just like the query command. (#17823)
• Patch zlib to fix compatibility with latest Xcode (#18000)
• profile: add profile_finish_ts (#18129)
• Use ctime in file digest cache key (#18105)
• Include cause when reporting ActionExecutionException (#18185)
• Check for the nullness of AspectValue. (#18186)
• Force the Bazel server Java runtime to use the root locale (#17733)
• Fix message generation of ActionExecutionException (#18257)

Android

• Added coverage metric support to android_local_test (#17467)
• Include build-tools/X.Y.Z/{lib,lib64}/** in the minimal set of SDK files used by the Android integration tests. (#17826)
• Fix worker and multiplex workers for DexBuilder and Desugar actions (#17965)

C++ / Objective-C

• Fix wasm dynamic library extension crash (#17765)
• Enable C++ deps pruning on Windows when PARSE_SHOWINCLUDES is available. (#17957)
• Add attribute provides = [CcInfo] to _cc_proto_aspect (#17979)
• Expose cc_proto_aspect as a top level symbol. (#17980)

CLI

• Handle SIGWINCH under bazel run //some:test (i.e. test rules) correctly. (#17760)
• Use less subshells and tees in running tests with bazel run. (#17869)

Configurability

• Allow multiple matching select branches if they resolve to the same value (#18066)
• cquery --output-starlark: better alias support (#17786)
• Fix crashes on select()able target_compatible_with attributes. (#18135)
• Add "did you mean?" suggestions for typoed rule attribute names (#17855)
• Turn applicable_licenses on platform() into a no-op. (#18089)

External Dependencies

• Added native.module_name() and native.module_version() to allow BUILD macro authors to acquire information about which Bazel module the current repo is associated with. (#17893)
• Added a new max_compatibility_level attribute to the bazel_dep directive, which allows version selection to upgrade a dependency up to the specified compatibility level. (#18178)
• Added module_ctx.is_dev_dependency, allowing an extension to see whether a tag is specified to be a dev dependency. (#17934)
• Added module_ctx.extension_metadata, allowing the extension to specify the list of repos the root module can use_repo on. If the root module violates this list, Bazel will print out a Buildozer command to automatically fix the use_repo directive. (#18174)
• Fixed an issue where WORKSPACE and WORKSPACE-loaded .bzl files couldn't see the Bzlmod root module's mappings when Bzlmod is enabled. (#17818)
• Added suggestions to invalid tag class errors. (#17896)
• Workspace relative paths are now supported in --override_module. (#17906)
• Fail early if use_extension has a bad label (#17926)
• Added dev_dependency to register_{execution_platforms,toolchains}. (#18259)

Java

• Silence setlocale warnings in Java stub (#17741)
• Split darwin java_tools to x86_64 and arm64 (#18197)
• Upgrade Azul JDK 17 archives. (#17852)
• Add version to JavaRuntimeInfo (#17913)
• Update default_java_toolchain.bzl to fix a regression (#18225)
• Updated java_tools to v12.3 to fix BazelTestRunner compatibility with jre8 (#18328)

Python

• Removed temporary module space created for zip-based binaries (#17764)
• Set envvar for runfiles manifest, not runfiles dir, when using a manifest (#18133)

Remote Execution

• Skip empty directories instead of throwing in the prefetcher. (#17718)
• Remove actionId from RemoteFileArtifactValue. (#17724)
• Correctly handle templated tree artifacts in the prefetcher. (#17735)
• [credentialhelper] Ignore failing to provide request (#17745)
• [remote] upload: treat ALREADY_EXISTS as success (#17732)
• Fix data race in prefetcher. (#17744)
• Clear all remote metadata if any of them are evicted from remote cache (#17770)
• Fix seeking of empty chunkers. (#17830)
• Rework ByteStreamUploader early return logic. (#17832)
• Avoid unnecessary copying when building Merkle trees. (#17930)
• Cache Merkle trees for tree artifacts. (#17998)
• Deduplicate concurrent computations of the same Merkle tree. (#18015)
• Add exception message to 'failed to create output directory' (#18067)
• Prevent failures creating output directories (#18062)
• Gracefully handle output symlinks with BwoB (#18106)
• Automatically retry the build if encountered remote cache eviction error (#18171)
• Allow remote retry max delay to be user configurable (#18061)
• Rename --experimental_remote_grpc_log to --remote_grpc_log (#18193)
• Construct TreeArtifactValues on multiple threads. (#18194)
• Fix crash on multiple output symlinks with BwoB (#18226)
