extensions: register functions always at loading extension (issue5601)...
extensions: register functions always at loading extension (issue5601) Before this patch, functions defined in extensions are registered via extra loaders only in _dispatch(). Therefore, loading extensions in other code paths like below omits registration of functions. - WSGI service - operation across repositories (e.g. subrepo) - test-duplicateoptions.py, using extensions.loadall() directly To register functions always at loading new extension, this patch moves implementation for extra loading from dispatch._dispatch() to extensions.loadall(). AFAIK, only commands module causes cyclic dependency between extensions module, but this patch imports all related modules just before extra loading in loadall(), in order to centralize them. This patch makes extensions.py depend on many other modules, even though extensions.py itself doesn't. It should be avoided if possible, but I don't have any better idea. Some other places like below aren't reasonable for extra loading, IMHO. - specific function in newly added module: existing callers of extensions.loadall() should invoke it, too - hg.repository() or so: no-repo commands aren't covered by this. BTW, this patch removes _loaded.add(name) on relocation, because dispatch._loaded is used only for extraloaders (for similar reason, "exts" variable is removed, too).
