#require pytype py3 slow $ cd $RUNTESTDIR/.. Many of the individual files that are excluded here confuse pytype because they do a mix of Python 2 and Python 3 things conditionally. There's no good way to help it out with that as far as I can tell, so let's just hide those files from it for now. We should endeavor to empty this list out over time, as some of these are probably hiding real problems. mercurial/bundlerepo.py # no vfs and ui attrs on bundlerepo mercurial/context.py # many [attribute-error] mercurial/crecord.py # tons of [attribute-error], [module-attr] mercurial/debugcommands.py # [wrong-arg-types] mercurial/dispatch.py # initstdio: No attribute ... on TextIO [attribute-error] mercurial/exchange.py # [attribute-error] mercurial/hgweb/hgweb_mod.py # [attribute-error], [name-error], [wrong-arg-types] mercurial/hgweb/server.py # [attribute-error], [name-error], [module-attr] mercurial/hgweb/wsgicgi.py # confused values in os.environ mercurial/httppeer.py # [attribute-error], [wrong-arg-types] mercurial/interfaces # No attribute 'capabilities' on peer [attribute-error] mercurial/keepalive.py # [attribute-error] mercurial/localrepo.py # [attribute-error] mercurial/manifest.py # [unsupported-operands], [wrong-arg-types] mercurial/minirst.py # [unsupported-operands], [attribute-error] mercurial/pure/osutil.py # [invalid-typevar], [not-callable] mercurial/pure/parsers.py # [attribute-error] mercurial/pycompat.py # bytes vs str issues mercurial/repoview.py # [attribute-error] mercurial/sslutil.py # [attribute-error] mercurial/testing/storage.py # tons of [attribute-error] mercurial/ui.py # [attribute-error], [wrong-arg-types] mercurial/unionrepo.py # ui, svfs, unfiltered [attribute-error] mercurial/utils/memorytop.py # not 3.6 compatible mercurial/win32.py # [not-callable] mercurial/wireprotoframing.py # [unsupported-operands], [attribute-error], [import-error] mercurial/wireprotoserver.py # line 253, in _availableapis: No attribute '__iter__' on Callable[[Any, Any], Any] [attribute-error] mercurial/wireprotov1peer.py # [attribute-error] mercurial/wireprotov1server.py # BUG?: BundleValueError handler accesses subclass's attrs TODO: use --no-cache on test server?
