Probably would have been better as 0.9.1 then, since we're still <1.0.


the bounds of dev-foo are dev-foo and dev-foo I guess, much like an `=1.0.0` constraint. It's not a range, so fairly easy to handle. But not sure how it goes with version_compare though, maybe need to convert them all to 9999999-dev like we do for dev-master. In any case unlikely to happen for the php version check use case..


Man, there is no need, because there is the [cakephp3 branch](https://github.com/mirko-pagliai/cakephp-assets/tree/cakephp3).

If something doesn't work, you can open an issue, or feel free to participate in the existing repository! :-)


[Régis Hanol posted](https://review.discourse.org/t/feature-add-hidden-setting-to-disable-configuration-of-inventory-bucket/8280/2):

There should be a test for that ;)


Gah... my bad. Fixed in https://github.com/craftcms/cms/commit/71fd49de4c3e838a51d793ea2699deff9ef0c9ae


All the above looks a lot better I gotta say :)

Nit: JS will allocate this object on every call. You could put it at the top level and as three constants (`const NONE = 0` etc.), but this is clear enough that you can just use numbers directly.

WARNING: [UnusedNamespace] Unused namespace declaration xmlns:android; already declared on the root element
 Unused namespace declarations take up space and require processing that is not necessary


WARNING: [Autofill] Missing `autofillHints` attribute
 Specify an `autofillHints` attribute when targeting SDK version 26 or higher or explicitly specify that the view is not important for autofill. Your app can help an autofill service classify the data correctly by providing the meaning of each view that could be autofillable, such as views representing usernames, passwords, credit card fields, email addresses, etc.

The hints can have any value, but it is recommended to use predefined values like 'username' for a username or 'creditCardNumber' for a credit card number. For a list of all predefined autofill hint constants, see the `AUTOFILL_HINT_` constants in the `View` reference at https://developer.android.com/reference/android/view/View.html.

You can mark a view unimportant for autofill by specifying an `importantForAutofill` attribute on that view or a parent view. See https://developer.android.com/reference/android/view/View.html#setImportantForAutofill(int).


WARNING: [LabelFor] Missing accessibility label: provide either a view with an `android:labelFor` that references this view or provide an `android:hint`
 Editable text fields should provide an `android:hint` or, provided your `minSdkVersion` is at least 17, they may be referenced by a view with a `android:labelFor` attribute.

When using `android:labelFor`, be sure to provide an `android:text` or an `android:contentDescription`.

If your view is labeled but by a label in a different layout which includes this one, just suppress this warning from lint.


You need to fix all your test scripts to pass -no_init to openroad so it
doesn't read .openroad
before it runs the test.

It worked after I commented out everything in my .openroad.

You seem to be right. `D_PostEvent()` stores an array of `event_t` and not of pointers to `event_t`.


Call it `Strung` :trollface:


`attempts`


are these already set to 64 ?

@SergeiMikhailovskii catching exception when you could check the array length ahead is not very good practice. I would recommend you to verify if `address` array is empty return `null` and show the toast. Otherwise parse `address[0]` into `LatLng` object


@JuliaRegistrator register()


it uses file descriptor IN as opposed to Console In. And for some other reason. I suggested we send a PR for documentation purpose.


numElements 应该写成 num_elements 或 elements_number

Ik zal ff checken wat jij hebt aangepast.
