[bazel] Sketching out HelloWorld sk_app using GL bazel run //example:hello_world --config=clang causes a window to open and draws a circle and a square. Text to follow in a future CL. To make this work, I had to get rid of musl and use glibc. All the shared libraries (.so files) that were pre-built and available for download (e.g. from https://packages.debian.org/bullseye/amd64/libgl1/download) were compiled against glibc. When I tried to run a program statically linked with musl and dynamically linked against things using glibc, I got a segmentation fault on things like calloc(). Initial attempts to use glibc had failed because it was thought that the libc.so.6 file could only be referred to by absolute path (and thus Bazel would not be happy about it). As it turns out, that was simply a misconfiguration of the builtin_sysroot parameter to cc_common.create_cc_toolchain_config_info (see //toolchain/clang_toolchain_config.bzl). By setting that to `external/clang_linux_amd64` and not `external/clang_linux_amd64/usr`, the libc binary which had been extracted to `external/clang_linux_amd64/lib/x86_64-linux-gnu` was perfectly reachable from `external/clang_linux_amd64/usr/usr/lib/x86_64-linux-gnu/libc.so` To bring in the shared libraries to link against (e.g. X11, GL) I made build_toolchain.bzl easier to modify in that we simply need to add a debian download url and sha256 hash to a list (rather than having to plumb this through via arguments). Recommended Review Order: - example/BUILD.bazel (not sure if we always want to set bare link arguments like that or if we want to use "features" to pass those along to the toolchain). - tools/sk_app/BUILD.bazel to see initial cc_library for wrapping sk_app code. - toolchain/build_toolchain.bzl to see removal of musl and new list of debs. - toolchain/clang_toolchain_config.bzl (where use of the no-canonical-prefixes was key to compilation success). Notice also that we statically linked libc++ (I did not have any shared libraries for it locally, so I guessed a typical developer might not either). - Rest of toolchain/ for trivial renames. - bazel/Makefile to see extra docs on those targets and a new target that compiles all the exes so far for a quick way to test the build. - third_party/BUILD.bazel and src/gpu/BUILD.bazel which have non-generated changes.

[bazel] Compile gms for wasm and WebGL PS 1 is re-generating existing BUILD.bazel files PS 2 is generating BUILD.bazel files for tests/gms PS 3+ makes modifications to build all of the gms and tests. It is recommended to view this CL with just a diff between PS 2 and the end, due to the large amount of generated changes in PS 1 and 2. We make a filegroup for the gms and tests because they need to be compiled as one large blob in order for the registries to work. Maybe in the future we will break these up, but at least for WASM/JS, the overhead of starting a browser for each new test would likely grind things to a halt, so we just group them all together for now. It's also the most similar to what we currently do. In gm/BUILD.bazel and tests/BUILD.bazel, we add a cc_library that encapsulates all of the deps of the tests, so we can easily include that the build. These were discovered via trial and error, not anything automatic or systematic. The is_skia_dev_build config_setting is very similar to the GN equivalent from which it was based. The list of gms and tests to skip (e.g. which are incompatible with WASM) was determined by building the wasm bundle: modules/canvaskit$ make bazel_gms_release tools/run-wasm-gm-tests$ make run_local_debug # Don't forget to click the button on the screen after the # browser loads This way of invoking the tests will be replace soon with `bazel test <something>`. As such, I didn't bother fully documenting the current way. Suggested review order: - modules/canvaskit/BUILD.bazel taking note that we always use profiling-funcs to make the stacktraces human readable. - gm/BUILD.bazel and tests/BUILD.bazel to see the lists of gms/tests. Notice the tests are roughly partitioned because we don't support things like vulkan/PDF in the wasm build and we will want a way to not build certain tests for certain configurations - tools/* noting some of the cc_libraries added to make dependencies easier to add when needed. - All other files.

[infra] Add SkParagraph (harfbuzz, ICU) to Canvaskit Bazel build. As a follow-up to https://skia-review.googlesource.com/c/skia/+/476219, this sketches out how we can maybe use cc_library for the things in //modules to make sure something in //src doesn't depend on anything in //modules, for example. The following succeeds: bazel build //modules/skparagraph:skparagraph --config=clang \ --shaper_backend=harfbuzz_shaper --with_icu As does `make bazel_canvaskit_debug` in //modules/canvaskit Suggested Review Order: - third_party/BUILD.bazel for ICU and harfbuzz rules. Pay special attention to the genrules used to call the python script for turning the icu .dat file into .S or .cpp. - bazelrc and bazel/ for new flags and defines that control use of ICU and harfbuzz. Unlike GN, with the public_defines that get added in automatically if icu or harfbuzz is depended upon, we need to set the defines at the top level. This necessity might go away if we change the atoms to depend on //modules/skshaper, which could define that flag. - Top level BUILD.bazel files in //modules/skparagraph, //modules/skshaper, //modules/skunicode, //modules/canvaskit - All other .bazel file changes are automatic.

[canvaskit] Add skottie to Bazel build PS 1 regenerates existing Bazel files PS 2 adds generated Bazel files to skottie and its dependencies, as well as incorporating it into CanvasKit. This changes the version of Bazel we use to 5.0.0 (recently released).We had been using a pre-release of 6.0 because we wanted the new features in one of the 5.0 release candidates, but not the regression that was there (and reverted before the full 5.0 release). I'd like to stick to the latest stable Bazel release where possible. Suggested Review Order: - //modules/skottie/BUILD.bazel (this was hand written to encapsulate the skottie library). The files in the deps are based on skottie.gni. - //modules/skresources/BUILD.bazel and //modules/sksg/BUILD.bazel which expose all sources - //third_party/file_map_for_bazel.json which ignores the ffmpeg libraries (we won't actually build the SkVideoDecoder stuff because HAVE_VIDEO_DECODER is not set). - //modules/canvaskit/BUILD.bazel which makes use of the skottie library and includes the interface skottie.js file. - .bazelversion which changes the Bazel version used (e.g. by Bazelisk). - All other changes should be auto-generated or related to deleted files.

[bazel] Make use of test_on_env to spin up server for gms In order to extract the PNG files produced by our CanvasKit gms, we need our JS tests to POST them to a server which can write to disk. The easiest way to do this is to use the test_on_env rule defined in the Skia Infra repo for exactly this purpose. This required https://skia-review.googlesource.com/c/buildbot/+/510717 to be able to configure the binary correctly and https://skia-review.googlesource.com/c/buildbot/+/511862, for nicer debugging so the skia-infra dep was updated via the following commands: $ go get go.skia.org/infra@d8a552a29e02e0b3b6db191919c8b96ed5ebd192 $ go mod download $ make -C infra/bots train $ make -C bazel gazelle_update_repo This caused many automated changes to infra/bots/tasks.json The flow is: 1. User types bazelisk test :hello_world_test_with_env 2. The test_on_env rule starts gold_test_env and waits for the file defined in $ENV_READY_FILE to be created. 3. gold_test_env starts a web server on a random port. It writes this port number to $ENV_DIR/port. Then, it creates $ENV_READY_FILE to signal ready. 4. test_on_env sees the ready file and then starts the karma_test rule. (Reminder: this is a bash script which starts karma using the Bazel-bundled chromium). 5. The karma_test rule runs the karma.bazel.js file (which has been injected with some JS code to fill in Bazel paths and settings) using Bazel-bundled node. This reads in the port file and sets up a Karma proxy to redirect /gold_rpc/report to http://localhost:PORT/report 6. The JS tests run via Karma (and do assertions via Jasmine). Some tests, the gms, make POST requests to the proxy. 7. gold_test_env gets these POST requests writes the images to a special Bazel folder on disk as defined by $TEST_UNDECLARED_OUTPUTS_DIR. 8. test_on_env identifies that the tests finish (because the karma_test script returns 0). It sends SIGINT to gold_test_env. 9. gold_test_env stops the webserver. The special Bazel folder will zip up anything inside it and make it available for future rules (e.g. a rule that will upload to Gold via goldctl). Suggested Review Order: - bazel/karma_test.bzl to see the test_on_env rule bundled into the karma_test macro. I chose to put it there because it might be confusing to have to define both a karma_test and test_on_env rule in the same package but not be able to call one because it will fail to talk to the server. - gold_test_env.go to see how the appropriate files are written to signal the environment is ready and the handlers are set up. - karma.bazel.js to see how we make our own proxy given the port from the env binary. The fact that we could not create our own proxy with the existing karma_test rule was why the chain ending in https://skia-review.googlesource.com/c/skia/+/508797 had to be abandoned. - tests/*.js to see how the environment is probed via /healthz and then used to make POST requests with data. - Everything else.
