    runtime: access modules via a slice · 54ec7b07
    David Crawshaw authored
    The introduction of -buildmode=plugin means modules can be added to a
    Go program while it is running. This means there exists some time
    while the program is running with the module is on the moduledata
    linked list, but it has not been initialized to the satisfaction of
    other parts of the runtime. Notably, the GC.
    
    This CL adds a new way of access modules, an activeModules function.
    It returns a slice of modules that is built in the background and
    atomically swapped in. The parts of the runtime that need to wait on
    module initialization can use this slice instead of the linked list.
    
    Fixes #17455
