sorry, I red just the last post.
__gshared has no influence on this.
Indeed, it was just what the OP suspected as the culprit.
auto cmds = CONFIG.commands;
cmds["list"] = new Command(...);
cmds is a thread local variable referencing the shared AA. But
if you add new elements to cmds, cmd will be reallocated and
the shared AA will remain unchanged. Though, updated values of
existing keys will be visible in the original, because no
relocation takes place.
This describes the semantics of regular arrays. Are you sure it
also applies to AAs? I thought they will keep referring to the
same data once they are initialized. But I might be mistaken...
If you want to change the original you need a pointer or a
reference (for a setter function).
auto cmds = &CONFIG.commands;
(*cmds)["list"] = new Command(...);
