feat(core): update schematic to migrate to explicit query timing #28983

devversion · 2019-02-26T17:54:26Z

Introduces an update schematic for the @angular/core package that
automatically migrates pre-V8 ViewChild and ContentChild queries to
the new explicit timing syntax. This is not required yet, but with Ivy, queries
will be "dynamic" by default. Therefore specifying an explicit query timing
ensures that developers can smoothly migrate to Ivy (once it's the default).

Read more about the explicit timing API here: #28810

Thanks so much for doing this! A few thoughts below.

LGTM for behavior. @alexeagle should probably look at bazel sections.

Note: Looks like linter is upset

alexeagle

no issues from Bazel

caretaker: I was able to get this green in g3 by

fixing the type-check error mentioned in a comment here
adding a new file third_party/javascript/angular2/rc/packages/core/schematics/BUILD containing

load("//javascript/typescript:build_defs.bzl", "ts_library")

licenses(["notice"])  # MIT License

ts_library(
    name = "schematics",
    srcs = glob(["migrations/**/*.ts"], exclude = [
        "migrations/static-queries/*.ts",
        "**/*_spec.ts",
    ]),
    deps = [
         "//third_party/javascript/node_modules/typescript:es2015.core",
         "//third_party/javascript/node_modules/typescript:typings",
    ]
)

note that this also has to be treated specially in copybara since this file would be g3-only.

The fundamental problem is that we don't share the BUILD files between github and g3. Would be an interesting project.

Fix no implicit returns G3 error. Move specs into packages/core/schematis/test/* folder

Mailed cl/236891637 to @AndrewKushnir so that the new schematics/ directory here won't be compiled in g3 yet

AndrewKushnir · 2019-03-05T20:11:01Z

Presubmit #2

AndrewKushnir · 2019-03-05T20:21:08Z

@alexeagle it looks like Presubmit and Guitar tests are still failing. Could you please help look into this?

AndrewKushnir · 2019-03-05T21:38:06Z

Presubmit #3 (after additional changes in g3)

AndrewKushnir · 2019-03-05T22:22:19Z

Presubmit was successful, I've merged this PR. Thanks everyone for the help!
