#13959 closed enhancement (fixed)

improve modules to not automatically augment the dojo module value

Reported by: Rawld Gill Owned by: Rawld Gill
Priority: low Milestone: 1.11
Component: Core Version: 1.7.0b1

As of 1.7, many modules attempt to return a module value but also modify dojo. In some cases this may be the intended semantics, but in many cases it is neither necessary nor desirable. For example, the dojo array functions (forEach, index, etc.) should be returned by the module that defines them (dojo/_base/array), but there is no need to automatically and unconditionally push them into the dojo object also.

Since much of the 1.x code and 1.x-dependent code in the wild depends on dojo being populated as such, it is impossible to make this change unconditionally in the 1.x line. The has feature flag "extend-dojo" (defaults to truthy), has been added which instructs modules to push their values into the dojo object. For example, the last few lines of dojo/_base/array look like this:

	array = {
		every:       everyOrSome(false),
		clearCache:  clearCache

	has("extend-dojo") && lang.mixin(dojo, array);

	/*===== return dojo.array; =====*/
	return array;

By setting extend-dojo to falsy, it is possible to load/use any module that leverages the feature without polluting the dojo object.

Note: this feature was originally named dojo-1x-base. It was renamed because the issue does not apply to base alone.

This is a meta ticket to track enhancing modules to conditionally use this pattern.

Meta ticket seems to not be actively used any more. Closing as fixed (at least as much as it's going to be for 1.x).
