Release 7.4.0 (2024-10-22)

Bazel 7.4.0 is a minor LTS release. It is fully backward compatible with Bazel 7.0 and contains selected changes by the Bazel community and Google engineers.

Configurability

• Bazel now supports all characters in the rlocation and target paths of runfiles and can be run from workspaces with a space in their full path. (#​23912)

External Deps

• Overrides in the root MODULE.bazel file are now ignored with --ignore_dev_dependency. (Overrides in non-root modules are already ignored.) (#​23550)
• Repository rules instantiated in the same module extensions can now refer to each other by their extension-specified names in label attributes. (#​23585)
• Bazel fetch and vendor command now supports --target_pattern_file for specifying target patterns. (#​23663)
• Patches to the module file in single_version_override are now effective as long as the patch file lies in the root module. (#​23757)
• override_repo and inject_repo can be used to override and inject repos in module extensions. (#​23938)
• When using vendor mode, the vendor dir is automatically ignored while package loading (#​23919)

Remote Execution

• Improve progress message in case there are no actions in flight, and display explicitly "no actions running" in that case. (#​23357)
• Added support for using a remote cache that evicts blobs and doesn't have AC integrity check (e.g. HTTP cache). (#​23561)
• Implemented disk cache garbage collection (#​23833)

C++ / Objective-C

• The new cc_static_library rule produces a static library that bundles given targets and all their transitive dependencies. It has to be enabled via --experimental_cc_static_library. (#​23392)
• Add conlyopts and cxxopts attributes to cc rules (#​23904)
• Auto-load with language specific rules that're removed from Bazel with --incompatible_autoload_externally (#​23906)

Release 7.2.0 (2024-06-10)

Bazel 7.2.0 is a minor LTS release. It is fully backward compatible with Bazel 7.0 and contains selected changes by the Bazel community and Google engineers.

C++ / Objective-C

• The default Unix C++ toolchain now supports the parse_headers feature to validate header files with --process_headers_in_dependencies. (#​22369)

CLI

• Bazel on Linux and BSD now respects the XDG_CACHE_HOME environment variable instead of assuming that ~/.cache/bazel is writable. (#​21817)

Configurability

• aquery: //foo:bar now means "all configured targets with label //foo:bar" instead of "choose an arbitrary configured target with label //foo:bar". This is in line with cquery behavior. (#​22135)
• Starlark command-line flags can now be referred to through alias targets. (#​22212)

External Deps

• Added a new flag --incompatible_disable_native_repo_rules to disable native repo rule usage in WORKSPACE. All native repo rules now have a Starlark counterpart that can be used in both WORKSPACE and Bzlmod; see #​22080 for more details. (#​22203)
• The format for MODULE.bazel.lock is now less likely to result in merge conflicts and is updated incrementally, with only new files downloaded from registries and existing ones taken from the repository cache (if configured). (#​22351)
• Added a new include() directive to MODULE.bazel files, which allows the root module file to be divided into multiple segments. (#​22204)
• Fixed certain deadlocks in repo fetching with worker threads (--experimental_worker_for_repo_fetching=auto). (#​22261, #​22573)
• bzlmod git_override now accepts the strip_prefix arg and passes it to the underlying git_repository call. (#​22137)
• The source.json file in registries now supports the overlay attribute in addition to patches. http_archive now has two more attributes, remote_file_urls and remote_file_integrity, to support this use case. (#​22325, #​22525)
• print statements in module files are now only executed for the root module and modules subject to non-registry overrides (e.g. local_path_override). (#​22263)
• The new refresh value for --lockfile_mode behaves like the update mode, but additionally forces a refresh of mutable registry content (yanked versions and missing module versions) when switched to or from time to time while enabled. (#​22371)
• bazel fetch now more reliably fetches repos required for a build by triggering the analysis phase. (#​21841)
• Label instances passed to print or fail as positional arguments are now formatted with apparent repository names (optimized for human readability). (#​22460)
• Changes to environment variables read via mctx.getenv now correctly invalidate module extensions. (#​22541)
• Git merge conflicts in MODULE.bazel.lock files can be resolved automatically. See https://bazel.build/external/lockfile#automatic-resolution for the required setup. (#​22650)

Local Execution

• Paths in the Linux sandbox are now again identical to those outside the sandbox, even with --incompatible_sandbox_hermetic_tmp. (#​22407)

Remote Execution

• The combined coverage report produced via --combined_report=lcov is now announced on the BES via the new CoverageReport event. (#​22327)
• The compact and full execution logs now contain start times for spawns (if available). (#​22341)
• Added a new flag --incompatible_modify_execution_info_additive, which causes the --modify_execution_info flag to become additive when specified multiple times. (#​22316)
• Added new flags --experimental_remote_output_service and --experimental_remote_output_service_output_path_prefix for remote output service

Starlark / Build Language

• Starlark min and max buitins now allow a key callback, similarly to sorted. (#​21960)
• native.package_relative_label can now be used in rule initializers.

Release 7.1.0 (2024-03-11)

Baseline: 8f4b115

Bazel 7.1.0 is a minor LTS release. It is fully backward compatible with Bazel 7.0 and contains selected changes by the Bazel community and Google engineers.

Configurability

• genrule now supports setting stamp = -1 to request conditional stamping (based on the value of the build's --stamp flag). (#​21512)

External Deps

• Added a flag --enable_workspace (defaults to True) that allows the user to completely disable WORKSPACE logic when turned off. We plan to change the default to False with Bazel 8. (#​20365)
• Added new repo rule and module extension APIs to watch arbitrary files or directory trees: (#​21435)
  • New methods repository_ctx.watch() and module_ctx.watch() allow changes to a path to trigger a refetch/re-evaluation of the repo/extension.
  • Several methods such as repository_ctx.read() and repository_ctx.template() gain a new watch parameter to allow them to watch for changes to the path in question.
  • path.readdir() now watches for changes under the directory by default.
  • New method repository_ctx.watch_tree() allows changes to anything transitively under a directory tree to trigger a repo refetch.
• Added path.is_dir to detect whether a path points to a directory.
• Added a new method repository_ctx.getenv, which allows Starlark repository rules to declare environment variable dependencies during the fetch, instead of upfront using repository_rule.environ. (#​20944)
• The flag --experimental_worker_for_repo_fetching now defaults to auto, which uses virtual threads from JDK 21 if it's available. This eliminates restarts during repo fetching. (#​21082)
• The new bazel mod tidy subcommand automatically updates use_repo calls in the MODULE.bazel file for extensions that use module_ctx.extension_metadata. (#​21265)
• bazel mod dump_repo_mapping <canonical repo name>... returns the repository mappings of the given repositories in NDJSON. This information can be used by IDEs and Starlark language servers to resolve labels with --enable_bzlmod. (#​21023)
• Added init_submodules attribute to git_override. Registries now support the git_repository type in source.json. (#​21036)
• Bazel's Bash completion can now complete external repository labels when using --enable_bzlmod. (#​21149)
• Fixed bazel fetch by replacing query with cquery as underlying implementation (#​21567, #​13847).
• The scheme for generating canonical repository names has changed to improve cacheability of actions across dependency version updates. Note that canonical names are not considered to be public API and can change at any time. See https://bazel.build/external/module#repository_names_and_strict_deps for advice on how to avoid hardcoding canonical repository names. (#​21316)
• Various methods and fields related to labels and repos are deprecated in favor of new options with clearer naming and intent. The deprecated APIs can be disabled by setting --noincompatible_enable_deprecated_label_apis. (#​20977)
  • native.repository_name() is deprecated in favor of the new native.repo_name().
  • Label.workspace_name is deprecated in favor of the new Label.repo_name.
  • Label.relative() is deprecated in favor of the new Label.same_package_label() alongside the existing native.package_relative_label() and Label().

Performance

• Make Bazel's RAM estimate container aware (#​20644)
  • On Linux, Bazel's RAM estimate for the host machine is now aware of container resource limits.
  • On macOS, Bazel no longer consistently overestimates the total RAM by ~5% (1024^2/1000^2).
  • On Windows, Bazel's RAM estimate is now generally more accurate as it is no longer influenced by JVM heuristics.
• Added a new --experimental_execution_log_compact_file flag to produce an execution log in a leaner format and with less runtime overhead. The //src/tools/execlog:converter tool may be used to convert it into one of the preexisting --execution_log_{json,binary}_file formats.
• Reduced the execution phase overhead for actions that create tree artifacts with a very large number of files (tens or hundreds of thousands).
• Made sandboxing and sandboxed workers faster. This is achieved by deleting files asynchronously, reusing runfiles, reducing copying and not stashing unnecessary tmp directories.

Python

• Fixed --incompatible_python_disallow_native_rules to work with targets at the top level (e.g. "//:foo") (#​17773)
• rules_python version increased from 0.4.0 to 0.22.1 in bazel_tools builtin module.

Remote Execution

• Bazel now respects expires from Credential Helpers. (#​21429)

Baseline:  d60ce2c7c86393638c77698c00c2168a7a936a53

Release Notes:

+ **[Incompatible]** This has the side effect of changing the message on unsuccessful builds from ``` FAILED: Build did NOT complete successfully (0 packages loaded) ``` to ``` ERROR: Build did NOT complete successfully ```
+ The new path variable `$(rlocationpath ...)` and its plural form `$(rlocationpaths ...)` can be used to expand labels to the paths accepted by the `Rlocation` function of runfiles libraries. This is the preferred way to access data dependencies at runtime and works on all platforms, even when runfiles are not enabled (e.g., on Windows by default).
+ The `aquery` and `cquery` commands now respect the `--query_file` flag just like the `query` command.
+ **[Incompatible]** the --experimental_async_execution flag is now a no-op.
+ **[Incompatible]** --experimental_replay_action_out_err is not a no-op.
+ **[Incompatible]** `cquery --output=files` also outputs source files.
+ removed outdated ctx.host_fragments
+ **[Incompatible]** When multiple --deleted_packages options are passed on the command line, they will be concatenated instead of the latest one taking effect.
+ removed outdated ctx.host_configuration
+ **[Incompatible]** JSON profile: Use doubles instead of strings for counter series.
+ Now that the host configuration is finished, `genrule` should prefer the use of `tools` and stop using `exec_tools`.
+ **[Incompatible]** --experimental_build_transitive_python_runfiles is flipped to false. See #​16303 for details
+ **[Incompatible]** --incompatible_python_disable_py2 is flipped to true. See #​17293 for details.
+ Update Android manifest merger to v30.1.3, and also drop support for legacy (pre-D8) desugaring.
+ Correctly encode double value positive infinity as "inf" instead of "+inf" for textprotos.
+ **[Incompatible]** When remote cache evicts blobs, Bazel will exit with code 39.
+ Add --use_target_platform_for_tests which uses the target platform for executing tests instead of the execution platform.
+ **[Incompatible]** `--features` only applies to targets built in the target configuration, and `--host_features` is used for the host / exec configuration (gated behind `--incompatible_use_host_features`)
+ Custom C++ rules on Windows calling cc_common.create_linking_context_from_compilation_outputs should review whether each target of the rule type should produce a dynamic library since a condition which blocked their creation has been moved to the rules from behind the API.
+ Add flag `--experimental_remote_cache_ttl` and set the default value to 3 hours.
+ making --incompatible_use_platforms_repo_for_constraints do nothing. Using constraints from @​bazel_tools//platforms with or without the flag will throw error with message "Constraints from @​bazel_tools//platforms have been removed. Please use constraints from @​platforms repository embedded in Bazel, or preferably declare dependency on https://github.com/bazelbuild/platforms"
+ **[Incompatible]** Bazel's local CPU resource on Linux is now container aware. Use `--local_cpu_resources`, `--loading_phase_threads` or `--jobs` to override.
+ Subsequent settings of --extra_execution_platforms now override previous settings, instead of adding them to a list. If you currently set --extra_execution_plat
