[BUGFIX beta] Deprecate importing htmlSafe and isHTMLSafe from @ember/string #19339

jamescdavis · 2021-01-17T19:43:31Z

As per RFC #236, this deprecates importing htmlSafe and isHTMLSafe from @ember/string.

The tracking issue for RFC #236 says that these will be deprecated via linting, but the linked issue is only a docs change that doesn't make it clear that importing from @ember/string is deprecated. There has been much confusion around whether this is actually deprecated (especially with regard to the @ember/string type definitions).

I'm hoping this can be backported to 3.24 since the the string prototype extensions were deprecated in that version.

We typically don't backport deprecations into release 🤔

packages/ember/index.js

+Ember.String.htmlSafe = deprecateImportFromString('htmlSafe', htmlSafe);
+Ember.String.isHTMLSafe = deprecateImportFromString('isHTMLSafe', isHTMLSafe);


Instead of returning a function that does the deprecation, can you make these a getter that issues the deprecation upon access (those getters would then return the original values)? There are other examples like that in this file.

That would look something like:

Object.defineProperty(Ember.String, 'htmlSafe', { enumerable: true, configurable: true, get() { // do the deprecation // then return the normal value } });

Should htmlSafe and isHTMLSafe get separate deprecation ids? I just made up ember-string.htmlsafe-ishtmlsafe. Is there a pattern I should be following here?

I also just invented the URL https://deprecations.emberjs.com/v3.x/#toc_ember-string-htmlsafe-ishtmlsafe
I'm not sure if there's a pattern I should follow there as well (I was looking at #19234).

Dealers choice (I think either is fine)😊

We usually figure out the urls by making the PR and grabbing them from the running app. Once the deprecation guide PR is merged, we can ensure that the URL is correct, then we can land this.

3.24 is also an LTS candidate, if that impacts any decision.

jamescdavis · 2021-01-18T17:31:12Z

@rwjblue I had based this on the approach used in #19234, but I like the getter approach better. Will update.

As far as backporting to 3.24, my thinking is this usage has already been deprecated for some time (as of the docs change) there was just no deprecation warning ever added or mention of it on http://deprecations.emberjs.com (which has caused confusion, to the point where someone has even removed the usage from the type defs). It's only come to a head recently because of ember-data's new dependency on the @ember/string package and its types overriding DT's, thus causing this usage to no longer typecheck (which I've fixed) making people believe the usage was removed. As @locks mentioned, being an LTS candidate, IMHO we should get a definitive answer as to the state of this usage in that release.

jamescdavis · 2021-01-18T17:39:04Z

As an another example of the confusion, here's a discussion from over a year ago: DefinitelyTyped/DefinitelyTyped#38571 (comment)

rwjblue · 2021-01-18T18:38:03Z

I'm all for providing a definitive answer, ensuring the docs have been updated and the deprecation guide has landed does that sufficiently.

Introducing deprecations in a patch release is just very bad form. For example, a decent number of apps and addon use "throw on deprecation" and releasing a new deprecation warning will start failing their CI. We have a train model for a reason, landing this now and pulling it into the current beta channel should be perfectly fine (especially RE: sending a clear signal).

jamescdavis · 2021-01-18T19:05:01Z

@rwjblue that makes perfect sense! Salsify is one of those apps! 😉
I'll update it to be since 3.25.

packages/ember/tests/reexports_test.js

+          'Ember.String.htmlSafe is exported correctly'
+        );
+      }, /Importing htmlSafe from '@ember\/string' is deprecated/);
+      assert.notEqual(glimmer.htmlSafe, undefined, 'Ember.String.htmlSafe is not `undefined`');


These asserts are based on

ember.js/packages/internal-test-helpers/lib/confirm-export.js

Lines 17 to 44 in 26f4aff

export default function confirmExport(Ember, assert, path, moduleId, exportName) {

try {

let desc = getDescriptor(Ember, path);

assert.ok(desc, `the ${path} property exists on the Ember global`);

if (typeof exportName === 'string') {

let mod = require(moduleId);

assert.equal(desc.value, mod[exportName], `Ember.${path} is exported correctly`);

assert.notEqual(mod[exportName], undefined, `Ember.${path} is not \`undefined\``);

} else if ('value' in desc) {

assert.equal(desc.value, exportName.value, `Ember.${path} is exported correctly`);

} else {

let mod = require(moduleId);

assert.equal(desc.get, mod[exportName.get], `Ember.${path} getter is exported correctly`);

assert.notEqual(desc.get, undefined, `Ember.${path} getter is not undefined`);

if (exportName.set) {

assert.equal(desc.set, mod[exportName.set], `Ember.${path} setter is exported correctly`);

assert.notEqual(desc.set, undefined, `Ember.${path} setter is not undefined`);

}

}

} catch (error) {

assert.pushResult({

result: false,

message: `An error occurred while testing ${path} is exported from ${moduleId}.`,

source: error,

});

}

but had to be a little different because it's now a getter in the "reexport" (not strictly a reexport now, I guess) and a value in the original mod.

Can you set enabled instead of available?

Suggested change

since: {

available: '3.25',

},

since: {

enabled: '3.25',

},

Until the deprecation stages RFC is fully rolled out, we are just using enabled for deprecations (it means that folks get the deprecation right away and don't have to opt in).

+      available: '3.25',
+    },
+    until: '4.0.0',
+    url: 'https://deprecations.emberjs.com/v3.x/#toc_ember-string-htmlsafe-ishtmlsafe',


Now that ember-learn/deprecation-app#758 is merged, can you double check the deployed URL to make sure this is right?

Looks good! Things seem to jump around after page load so you don't end up exactly in the right spot, but the anchor but the link does match what's in the TOC. This jumping issue seems to affect all the anchors.

I think the jumping around is the code blocks rendering. I'll make an issue!
