test_description='Test submodule--helper is-active
This test verifies that `git submodue--helper is-active` correctly identifies
submodules which are "active" and interesting to the user.

submodule: decouple url and submodule interest Currently the submodule.<name>.url config option is used to determine if a given submodule is of interest to the user. This ends up being cumbersome in a world where we want to have different submodules checked out in different worktrees or a more generalized mechanism to select which submodules are of interest. In a future with worktree support for submodules, there will be multiple working trees, each of which may only need a subset of the submodules checked out. The URL (which is where the submodule repository can be obtained) should not differ between different working trees. It may also be convenient for users to more easily specify groups of submodules they are interested in as opposed to running "git submodule init <path>" on each submodule they want checked out in their working tree. To this end two config options are introduced, submodule.active and submodule.<name>.active. The submodule.active config holds a pathspec that specifies which submodules should exist in the working tree. The submodule.<name>.active config is a boolean flag used to indicate if that particular submodule should exist in the working tree. Its important to note that submodule.active functions differently than the other configuration options since it takes a pathspec. This allows users to adopt at least two new workflows: 1. Submodules can be grouped with a leading directory, such that a pathspec e.g. 'lib/' would cover all library-ish modules to allow those who are interested in library-ish modules to set "submodule.active = lib/" just once to say any and all modules in 'lib/' are interesting. 2. Once the pathspec-attribute feature is invented, users can label submodules with attributes to group them, so that a broad pathspec with attribute requirements, e.g. ':(attr:lib)', can be used to say any and all modules with the 'lib' attribute are interesting. Since the .gitattributes file, just like the .gitmodules file, is tracked by the superproject, when a submodule moves in the superproject tree, the project can adjust which path gets the attribute in .gitattributes, just like it can adjust which path has the submodule in .gitmodules. Neither of these two additional configuration options solve the problem of wanting different submodules checked out in different worktrees because multiple worktrees share .git/config. Only once per-worktree configurations become a reality can this be solved, but this is a necessary preparatory step for that future. Given these multiple ways to check if a submodule is of interest, the more fine-grained submodule.<name>.active option has the highest order of precedence followed by the pathspec check against submodule.active. To ensure backwards compatibility, if neither of these options are set, git falls back to checking the submodule.<name>.url option to determine if a submodule is interesting.
