feat(ivy): support generation of flags for directive injection by mhevery · Pull Request #23345 · angular/angular

mhevery · 2018-04-12T19:30:53Z

This change changes:

compiler uses directiveInject instead of inject for Directives
unifies the flags in di as well as render3
changes the signature of directiveInject to match inject In prep for inject and directiveInject need bridging when used with Component.provides #23330
compiler now generates flags for injection.

Compiler portion of #23342
Prep for #23330

feat(ivy): support injection even if no injector present

Remove default injection value from inject / directiveInject since
it is not possible to set using annotations.
Module Injector is stored on LView instead of LInjector data
structure because it can change only at LView level. (More efficient)
Add ngInjectableDef to IterableDiffers so that existing tests can
pass as well as enable IterableDiffers to be injectable without
Injector

Looks good to me, except for the fdescribe

kara · 2018-04-12T19:34:34Z

Remove fdescribe?

kara · 2018-04-12T19:38:27Z

Did you mean to remove this? Looks like it's still used in this file.

Working on two things in one PR, reverted

LGTM

const flags = moveThatLogicFurtherDown(dependency); ?

vicb · 2018-04-12T20:07:58Z

rename template to factory or injectxxxyyy ? (comment, var name and expect)
(I'm also ok with removing this comment)
Use $r3$ instead of IDENT for consistency with other tests ?

do we want to be able to provide undefined by using a special value (ie {}) instead ?

I was thinking about it, and decided that it is not worth the complexity. We can always added later.

vicb · 2018-04-13T02:15:47Z

useful comment ?

updated comment.

trotyl · 2018-04-13T03:35:56Z

Why would compilation result lives in source code? Shouldn't it using @Injectable() decorator?

Few reasons:
1.) we currently don't compile core with ivy so the decorator does not get lowered.
2.) There is a circular dependency between the compiler and core which makes it hard for the compiler to compile tho core. Rather than solving that, we have opted for hand coding it.

This comment should probably be in the source code

IgorMinar · 2018-04-13T07:29:00Z

this PR changes the API surface. @mhevery let's discuss tomorrow before merging this.

mhevery · 2018-04-13T19:52:30Z

Discussed with @IgorMinar and we agreed to merge.

IgorMinar · 2018-04-13T20:19:48Z

we agreed because the api is wrong and needs to be corrected before the release.

Why change the order? It's a bitmask anyway o:
