2021-04-01Reorganize soong_build/main.go .Lukacs T. Berki
This makes it more easy to see what's happening under which modes. Modes are: - Regular builds - Mixed mode builds - bp2build - soong_docs Test: Presubmit + bootstrap_test.sh Change-Id: I06e3fcb84986b919be1cd9eb456531259ede1183
2021-03-24Merge "bp2build: add allowlist for package-level conversions."Jingwen Chen
2021-03-24Make null builds always be null builds.Lukacs T. Berki
Previously, soong.environment.used was written after build.ninja and if the amount of time that passed between the two was long enough, Ninja would decide that build.ninja is older than soong.environment.used and rebuild it. Test: test_null_build in bootstrap_test.sh in a loop. Change-Id: I5467da487e8e8f2646644b8a7fb9549b9ff18276
2021-03-24bp2build: add allowlist for package-level conversions.Jingwen Chen
This CL adds the support for specifying lists of directories in build/soong/android/bazel.go, which are then written into out/soong/bp2build/MANIFEST. Using this configuration, modules/directories can either default to bp2build_available: true or false, while still retaining the ability to opt-in or out at the module level. It also ensures that ConvertWithBp2Build returns true iff the module type has a registered bp2build converter. Test: go tests Test: demo.sh full Test: TreeHugger presubmits for bp2build and mixed builds. Change-Id: I0e0f6f4b1b2ec045f2f1c338f7084defc5d23a55
2021-03-23Make GENERATE_BAZEL_FILES=true correct.Lukacs T. Berki
This is achieved by writing soong.environment.used in Main() instead of as a side effect of a singleton. This makes a difference because build actions are not generated when GENERATE_BAZEL_FILES=true is set, therefore the side effect did not happen. Arguably, Main() is made worse by this change, but I don't want to tackle the problem of readably determining which mode soong_build is running in in this change. Test: Presubmits + the additional test. Change-Id: I66af2429aedf008762173eaaa55b828b4cf4328b

2021-03-17Embed minibp into soong_ui.Lukacs T. Berki
This requires linking Blueprint into soong_ui. It lets us avoid the complicated dance of Ninja files and shell scripts: now the information as to how soong_build is built is passed directly to Blueprint using a struct that contains all the information the command line arguments used to contain. The ability to run Blueprint from the command line is kept (for now). Some variables in bootstrap/command.go needed public accessor functions because soong_build reads them. This will be disentangled by moving the flag parsing to soong_build. The presence of the flag definitions in Blueprint means that soong_ui now also accepts them. This is not a problem in practice because they are ignored and because soong_ui itself is hidden behind a few layers of shell scripts. Test: Presubmits + the new bootstrap_test.sh .

2021-03-08Make it possible to debug soong_ui.Lukacs T. Berki
This works by setting the SOONG_UI_DELVE= environment variable to the port on which soong_ui should accept a Delve connection on. This is achieved by reusing the Delve execution logic between soong_ui and soong_build. Test: Manual. Change-Id: Id2c1d4b6faac1a4a3918c91030ce2239f7daf54f

This CL adds an additional CodegenMetrics return value to GenerateBazelTargets calls, which are called from bp2build, queryview, and their tests. For this UI, we only want to use it for bp2build, and not queryview or tests, since it's not useful for the former, and can pollute the CLI for the latter.

2021-02-05bp2build: fix BUILD file generation incrementality bug.Jingwen Chen
Before this change, changes to any Android.bp file would not trigger a re-run of bp2build/Soong, since the depfile for Soong's main output, the build.ninja file, didn't contain the list of Android.bp files. bp2build only reran when Soong itself changed, which happens regularly while developing bp2build, but not at all while modifying Android.bp files. This change correctly dumps the list of all Android.bp files in the tree to the depfile for out/soong/build.ninja, therefore correctly triggering a re-run of bp2build when any Android.bp file changes. Test: GENERATE_BAZEL_FILES=true m nothing; edit an Android.bp file; GENERATE_BAZEL_FILES=true m nothing -> successfully re-runs and regenerates out/soong/bp2build. Test: inspect out/soong/build.ninja.d manually Fixes: 179452534 Change-Id: Iad80c381b3afa38a4d4fafca035e46aa2a1f206a

2021-01-29bp2build: fix running from clean checkout.Jingwen Chen
bp2build is a Soong mode that returns as soon as the BUILD files are generated. This causes it not generate the build.ninja file, which the Ninja process executing soong_build itself expects to produce as an output. If there isn't an existing build.ninja file generated from a previous build, GENERATE_BAZEL_FILES=true m nothing will fail. This CL generates the expected files as a workaround, and also makes GENERATE_BAZEL_FILES=true skip the Kati/Ninja steps in soong_ui since they aren't needed. Test: rm -rf out/ && GENERATE_BAZEL_FILES=true m nothing && m libc Fixes: 178683777 Change-Id: I2515ef7961682d2be5f096ed24831cc185165a67
2021-01-26bp2build: introduce CodegenMode.Jingwen Chen
The CodegenMode enum helps to differentiate between bp2build and queryview modes of generating BUILD files from the Soong module graph. bp2build is used for generating BUILD files from an unconfigured Soong module graph for Soong->Bazel conversion, whereas QueryView is a front-end for querying the existing Soong configured module graph with Bazel query.

2021-01-21bp2build: framework for generating BazelTargetModules.Jingwen Chen
This CL creates the framework necessary for generating BazelTargetModules from regular Soong Android modules. BazelTargetModules are code-generated into Bazel targets in BUILD files. See the follow-up CL for examples of creating filegroup/genrule BazelTargetModules. Test: GENERATE_BAZEL_FILES=true m nothing # creates out/soong/bp2build with no BUILD files, because there are no BazelTargetModules in the module graph.

2021-01-19Implement code-generation step for bp2build.Jingwen Chen
Implement bp2build codegen as a discrete step that runs after an alternatively registered pipeline of mutators, instead of a presingleton. bp2build codegen requires a Context that supports VisitAllModules and PathContext, so this CL also makes a BpToBuildWrapperContext that conforms to PathContext by adding two method implementations.

2021-01-07Refactor queryview.Liz Kammer
Splits queryview into queryview and bp2build. The latter runs as a presingleton (could be converted to a singleton). This prevents needing to run soong_ui a subsequent time to build the query. Queryview remains as a separate step to prevent increasing runtime due to this generation every time Soong runs. Currently this is running as a presingleton as this gives a translation of Android.bp files after only LoadHooks have run, no mutators.

This CL adds a new CONVERT_TO_BAZEL env var, and a bp2build goal. It reuses the queryview architecture, but registers no mutators before converting to BUILD files. This gives us a blank slate of the module graph to work with, and create a shadow/alternate pipeline of mutators to converge the Bazel BUILD graph to be semantically equivalent with the Android.bp graph (after apply its current set of mutators). The command to do so is: $ CONVERT_TO_BAZEL=true m bp2build To not clobber with queryview, the generated files are in out/soong/bp2build.

2020-12-03Merge "Remove soong.config, FileConfigurableOptions, MegaDevice config."Jingwen Chen
2020-11-27Generalize the handling of dist tagsPaul Duffin
Previously in order to make use of dist entries with tag properties it was necessary for each module type to be modified to store the results of GenerateTaggedDistFiles(module) in the AndroidMkEntry.DistFiles property. This change generalizes that mechanism to work across all module types. This change does improve the behavior of a couple of tests where previously a dist with tag property was ignored because tagged dist files were not available now it is used correctly. Some module types do not implement OutputFileProducer interface and so they cannot handle dist with tag properties. This change makes it an error to attempt to do that. That necessitated adding OutputFiles(tag) method to customModule in queryview_test.go as some of the tests in that file used dist entries with tag properties. Follow up changes will remove the code that was made redundant by this. Test: m nothing m dist sdk - before and after this change, compare result to make sure that there are no significant differences. Bug: 174226317 Change-Id: Ifc54d67db10ce0d0fe8179c05b97a2be2113be4e

2020-08-21Surface module properties as Bazel BUILD target attributes in the Bazel overlayJingwen Chen
This patchset changes bazel_overlay to generate soong_module as a macro, instead of a rule, and generate module properties in the BUILD files as kwargs to the soong_module macro. Here's a sample of the new BUILD files with module properties: bionic/libdl/BUILD.bazel: https://paste.googleplex.com/6484466996346880?raw art/build/apex/BUILD.bazel: https://paste.googleplex.com/5461276001042432?raw bionic/apex/BUILD.bazel: https://paste.googleplex.com/4932795173437440?raw soong_module is now a macro that conditionally expands to underlying soong_<module type> rules with statically defined attributes. In this CL, we are starting with a hardcoded filegroup rule definition to demonstrate the conditional rule loading within the soong_module macro. If the module_type matches an existing Bazel rule, soong_module forwards the entire **kwargs into the rule, which Bazel typechecks. Non-filegroup module types will be expanded into generic_soong_module, but with the kwargs dropped. This approach allows us to: 1) Programmtically generate soong_<module type> rules for all module types available in Soong, together with the statically defined attribute types in `attrs`. 2) Incrementally migrate and test individual module types from generic_soong_module to their module rule shims. 3) Swap out the module rule shims to the actual Bazel rules (e.g cc_library, java_library) and perform attribute manipulation in Starlark itself.

2020-08-06Create a AOSP Bazel overlay workspace with SoongJingwen Chen
The Bazel overlay is a directory at out/soong/bazel_overlay that replicates the layout of the AOSP Soong module tree, but as a Bazel workspace. Each Soong module variant is represented as a BUILD target created with the `soong_module` rule. To create this overlay, run `m bazel_overlay`. A `soong_module` target can depend on other `soong_module` targets. These dependencies replicate each module's `directDeps` in the Blueprint graph, just before `PrepareBuildActions`. This enables users to use bazel query as a way to introspect the Soong module graph. For example, - Direct reverse dependencies of //bionic/libc:generated_android_ids in //bionic/libc/...: $ bazel query 'rdeps(//bionic/libc/..., //bionic/libc:generated_android_ids, 1)' //bionic/libc:libc_bionic_ndk--android_recovery_arm_armv7-a-neon_static //bionic/libc:libc_bionic_ndk--android_ramdisk_arm_armv7-a-neon_static //bionic/libc:libc_bionic_ndk--android_arm_armv7-a-neon_static_com.android.runtime //bionic/libc:libc_bionic_ndk--android_arm_armv7-a-neon_static //bionic/libc:generated_android_ids - Why does com.android.runtime depend on lzma? $ bazel query 'somepath(//bionic/apex:com.android.runtime--android_common_com.android.runtime_image, //external/lzma/...)' //bionic/apex:com.android.runtime--android_common_com.android.runtime_image //bionic/libc/malloc_debug:libc_malloc_debug--android_arm_armv7-a-neon_shared_com.android.runtime //system/core/libunwindstack:libunwindstack--android_arm_armv7-a-neon_shared_com.android.runtime //external/lzma/C:liblzma--android_arm_armv7-a-neon_shared_com.android.runtime - What does the dep graph of //bionic/libc:crtbegin_so look like? $ bazel query 'deps(//bionic/libc:crtbegin_so--android_arm_armv7-a-neon)' --output=graph > graph.in && dot -Tpng < graph.in > graph.png https://photos.app.goo.gl/DfsdoFRNsRjGwTmy8 Test: croot && m bazel_overlay && cd out/soong/bazel_overlay && bazel query //... && bazel query 'rdeps(//bionic/libc/..., //bionic/libc:generated_android_ids, 1)' Signed-off-by: Jingwen Chen <jingwen@google.com> Change-Id: I3bf40309bfb2d963bb8a688706385a57ee304c37#
