exthelper: support the option argument when registering a command Largefiles uses this 5th argument with push and pull, so this will be tested in the next commit. I assume the reason for unrolling and reforming the tuple in each finalxxxsetup() is to validate that something proper was passed in when registering. But it's better to explode when decorating than during the delayed actual registration.

largefiles: port configitems to exthelper It looks like dynamicdefault was referenced in a non-standard way.

remotefilelog: use repo.local() instead of isinstance()

exthelper: add a cautionary note about adding attributes to containers

exthelper: drop a compatibility shim with '^command' syntax This syntax was dropped in fa88170c10bb.

wireproto: in batch queries, support queries with immediate responses listkeys and pushkey return without querying the remote when the remote doesn't support such queries. Before this change, the batching code didn't handle this convention, resulting in this kind of error: $ hg pull ssh://user@dummy/repo1 -r tip -B a pulling from ssh://user@dummy/repo1 remote: ** Unknown exception encountered with possibly-broken third-party extension disable-lookup remote: ** which supports versions unknown of Mercurial. remote: ** Please disable disable-lookup and try your action again. remote: ** If that fixes the bug please report it to the extension author. remote: ** Python 2.7.15+ (default, Oct 2 2018, 22:12:08) [GCC 8.2.0] remote: ** Mercurial Distributed SCM (version 4.8.1+586-ef54bd33b476+20181224) remote: ** Extensions loaded: disable-lookup remote: Traceback (most recent call last): remote: File "/tmp/hgtests.i66Npc/install/bin/hg", line 43, in <module> remote: dispatch.run() remote: File "/tmp/hgtests.i66Npc/install/lib/python/mercurial/dispatch.py", line 99, in run remote: status = dispatch(req) remote: File "/tmp/hgtests.i66Npc/install/lib/python/mercurial/dispatch.py", line 225, in dispatch remote: ret = _runcatch(req) or 0 remote: File "/tmp/hgtests.i66Npc/install/lib/python/mercurial/dispatch.py", line 376, in _runcatch remote: return _callcatch(ui, _runcatchfunc) remote: File "/tmp/hgtests.i66Npc/install/lib/python/mercurial/dispatch.py", line 384, in _callcatch remote: return scmutil.callcatch(ui, func) remote: File "/tmp/hgtests.i66Npc/install/lib/python/mercurial/scmutil.py", line 166, in callcatch remote: return func() remote: File "/tmp/hgtests.i66Npc/install/lib/python/mercurial/dispatch.py", line 367, in _runcatchfunc remote: return _dispatch(req) remote: File "/tmp/hgtests.i66Npc/install/lib/python/mercurial/dispatch.py", line 1021, in _dispatch remote: cmdpats, cmdoptions) remote: File "/tmp/hgtests.i66Npc/install/lib/python/mercurial/dispatch.py", line 756, in runcommand remote: ret = _runcommand(ui, options, cmd, d) remote: File "/tmp/hgtests.i66Npc/install/lib/python/mercurial/dispatch.py", line 1030, in _runcommand remote: return cmdfunc() remote: File "/tmp/hgtests.i66Npc/install/lib/python/mercurial/dispatch.py", line 1018, in <lambda> remote: d = lambda: util.checksignature(func)(ui, *args, **strcmdopt) remote: File "/tmp/hgtests.i66Npc/install/lib/python/mercurial/util.py", line 1670, in check remote: return func(*args, **kwargs) remote: File "/tmp/hgtests.i66Npc/install/lib/python/mercurial/commands.py", line 5257, in serve remote: s.serve_forever() remote: File "/tmp/hgtests.i66Npc/install/lib/python/mercurial/wireprotoserver.py", line 797, in serve_forever remote: self.serveuntil(threading.Event()) remote: File "/tmp/hgtests.i66Npc/install/lib/python/mercurial/wireprotoserver.py", line 804, in serveuntil remote: _runsshserver(self._ui, self._repo, self._fin, self._fout, ev) remote: File "/tmp/hgtests.i66Npc/install/lib/python/mercurial/wireprotoserver.py", line 656, in _runsshserver remote: rsp = wireprotov1server.dispatch(repo, proto, request) remote: File "/tmp/hgtests.i66Npc/install/lib/python/mercurial/wireprotov1server.py", line 74, in dispatch remote: return func(repo, proto, *args) remote: File "/tmp/hgtests.i66Npc/install/lib/python/mercurial/wireprotov1server.py", line 195, in batch remote: data[k] = vals[k] remote: KeyError: 'namespace' abort: unexpected response: empty string [255] Differential Revision: https://phab.mercurial-scm.org/D5482
