deprecate is not available from @ember/debug pre 4.0.0
#441

In trying to fix this, I wound up at: ember-cli/ember-rfc176-data#431 |
|
So, starting analysis over, as changes to ember-rfc176-data did not fix my issue. The output of ;define("my-app-test-deprecate/app", ["exports", "ember-resolver", "ember-load-initializers", "my-app-test-deprecate/config/environment"], function (_exports, _emberResolver, _emberLoadInitializers, _environment) {
"use strict";
Object.defineProperty(_exports, "__esModule", {
value: true
});
_exports.default = void 0;
function _defineProperty(obj, key, value) { if (key in obj) { Object.defineProperty(obj, key, { value: value, enumerable: true, configurable: true, writable: true }); } else { obj[key] = value; } return obj; }
console.log(deprecate);
class App extends Ember.Application {
constructor() {
super(...arguments);
_defineProperty(this, "modulePrefix", _environment.default.modulePrefix);
_defineProperty(this, "podModulePrefix", _environment.default.podModulePrefix);
_defineProperty(this, "Resolver", _emberResolver.default);
}
}
_exports.default = App;
(0, _emberLoadInitializers.default)(App, _environment.default.modulePrefix);
});which aligns with the current error I'm getting in the stand-alone app / reproduction: reproduction: https://github.com/NullVoxPopuli/repo-repro-ember-cli-babel-441 |

Changing the "reproduction code" to: import { assert, deprecate } from '@ember/debug';
console.log(deprecate, assert);gives this output: ;define("my-app-test-deprecate/app", ["exports", "ember-resolver", "ember-load-initializers", "my-app-test-deprecate/config/environment"], function (_exports, _emberResolver, _emberLoadInitializers, _environment) {
"use strict";
Object.defineProperty(_exports, "__esModule", {
value: true
});
_exports.default = void 0;
function _defineProperty(obj, key, value) { if (key in obj) { Object.defineProperty(obj, key, { value: value, enumerable: true, configurable: true, writable: true }); } else { obj[key] = value; } return obj; }
console.log(deprecate, assert);
class App extends Ember.Application {
constructor() {
super(...arguments);
_defineProperty(this, "modulePrefix", _environment.default.modulePrefix);
_defineProperty(this, "podModulePrefix", _environment.default.podModulePrefix);
_defineProperty(this, "Resolver", _emberResolver.default);
}
}
_exports.default = App;
(0, _emberLoadInitializers.default)(App, _environment.default.modulePrefix);
});which is weird, cause now assert isn't defined either.... So it seems everything from |

I put some breakpoints into ember-cli-babel and see this in the config sent to babel:
So next step is to see what these plugins are doing |
|
As an aside, having these "watches" in ember-cli-babel's index.js is super helpful: I can skip the things that are being compiled that aren't my app (or whatever other code I'm trying to look at being compiled) |
|
ah-ha! There is no externalized helpers config! Let's see if adding that fixes the issue |
|
oh but wait! It's supposed to be added here: |
|
hmm |
|
So, this leads me to believe that ember-cli-babel is setting things up correctly, and we need to go deeper. next up: babel plugins! |
|
goofy thing (maybe correct thing?) with debugging this is that all the dependencies of my linked ember-cli-babel package are relative to that linked package. so I made the mistake of putting breakpoints in my app's babel plugins, but those babel plugins are not in use! |
|
looks like babel-plugin-debug-macros's goal is to remove imports. 🤔 so the |
|
ah-ha! the modules polyfill is ignoring assert, deprecate, warn, etc! booo!
|
|
this could make sense, if the debug-macros plugin was handling the |
|
Confirm! if I comment out lines 219, 220, and 221, then Progress! |
|
but this code was added in 2020.... why am I running in to this now? I need to investigate how |
|
ah, back in ember-cli-babel: // we have to use the global form when not compiling modules, because it is often used
// in the context of an `app.import` where there is no wrapped in an AMD module
if (!useModulesVersion) {
const ignore = _getEmberModulesAPIIgnore(parent, project);
return [
[require.resolve("babel-plugin-ember-modules-api-polyfill"), { ignore }],
];
}but this was also added in 2020 |
|
This is the PR that introduced these changes (or changed them): #371 |
|
but, why am I running in to this now? |
|
removing still points at babel-plugin-ember-modules-api-polyfill 🤔 |
|
bah, I need a break from this 😅 babel stuff is dizzying |

For whomever finds this useful thread, this has been fixed in this dependency: https://github.com/ember-cli/ember-rfc176-data/blob/master/CHANGELOG.md#bug-bug-fix Dependencies that depend on |
I was originally going to report this on the embroider repo, as I had thought it was a v2-addon issue.
But it is not!
reproduction is super easy:
Repro repo: https://github.com/NullVoxPopuli/repo-repro-ember-cli-babel-441
just run
ember testThis was discovered while trying to add
deprecateusage to a v2-addonover in this PR
In the scenarios test suite, it seems that any interaction from a v2
addon with deprecate from
@ember/debugcauses the test suite to hang.In a real app / addon ( < ember-source @ v4), a different behavior occurs (and what I was
trying to re-create in this change):
According to the docs for
@ember/debug,deprecateexists, so the above code should work (I don't yet know why -- first step is a failingtest reproduction, but ran in to the test suite hanging issue.)
For [email protected]+, the above issue is not present -- and judging by
how (I happen to know that) pre 3.27, all ember apis were on the
Emberglobal and that embroider has no compat-adapter for
@ember/debug,my hunch is that this is actually ember-cli-bable related -- but I
wanted to open a test here, since embroider has a much better
"e2e"-style test suite than ember-cli-babel does.
Also, the stack trace shows
babel-plugin-ember-modules-api-polyfill,which is managed by ember-cli-babel.
however in writing this commit message / PR description_, I've found
that this behavior exists on a vanilla 3.25 app (new as of now).
So since the reproduction is not at all embroider or v2 addon related,
I'm going to post on ember-cli-babel
