revlog: refactor logic to compute nodemap file in separate function I will like to use it one more place. Differential Revision: https://phab.mercurial-scm.org/D9933

nodemap: make `_persist_nodemap` a public function I will like to have a utility function using which we can directly write out nodemap for a repository without going through the recloning process. This function seems like the one containing important pieces for that. Let's make it public. Differential Revision: https://phab.mercurial-scm.org/D9932

engine: 'if not, else' -> 'if, else' I personally feel that ``` if x: pass else: pass ``` is easier to read and edit than ``` if not x: pass else: pass ``` Next patches will add one more if-else clause. Differential Revision: https://phab.mercurial-scm.org/D9931

largefiles: properly pass kwargs into url.open The url.open function has acquired a lot of kwargs over the years. When running `hg import http://example.com/hg/diff/1`, since at least a708e1e4d7a8 in March, 2018, the calling sites for url.open try to pass a `sendaccept` parameter that largefiles' override doesn't accept. Currently that stack traces something like this: Traceback (most recent call last): File "/tmp/hgtests.sv744r5t/install/bin/hg", line 59, in <module> dispatch.run() File "/tmp/hgtests.sv744r5t/install/lib/python/mercurial/dispatch.py", line 143, in run status = dispatch(req) File "/tmp/hgtests.sv744r5t/install/lib/python/mercurial/dispatch.py", line 245, in dispatch status = _rundispatch(req) File "/tmp/hgtests.sv744r5t/install/lib/python/mercurial/dispatch.py", line 289, in _rundispatch ret = _runcatch(req) or 0 File "/tmp/hgtests.sv744r5t/install/lib/python/mercurial/dispatch.py", line 465, in _runcatch return _callcatch(ui, _runcatchfunc) File "/tmp/hgtests.sv744r5t/install/lib/python/mercurial/dispatch.py", line 475, in _callcatch return scmutil.callcatch(ui, func) File "/tmp/hgtests.sv744r5t/install/lib/python/mercurial/scmutil.py", line 155, in callcatch return func() File "/tmp/hgtests.sv744r5t/install/lib/python/mercurial/dispatch.py", line 455, in _runcatchfunc return _dispatch(req) File "/tmp/hgtests.sv744r5t/install/lib/python/mercurial/dispatch.py", line 1259, in _dispatch lui, repo, cmd, fullargs, ui, options, d, cmdpats, cmdoptions File "/tmp/hgtests.sv744r5t/install/lib/python/mercurial/dispatch.py", line 913, in runcommand ret = _runcommand(ui, options, cmd, d) File "/tmp/hgtests.sv744r5t/install/lib/python/mercurial/dispatch.py", line 1270, in _runcommand return cmdfunc() File "/tmp/hgtests.sv744r5t/install/lib/python/mercurial/dispatch.py", line 1256, in <lambda> d = lambda: util.checksignature(func)(ui, *args, **strcmdopt) File "/tmp/hgtests.sv744r5t/install/lib/python/mercurial/util.py", line 1867, in check return func(*args, **kwargs) File "/tmp/hgtests.sv744r5t/install/lib/python/mercurial/commands.py", line 4184, in import_ patchfile = hg.openpath(ui, patchurl, sendaccept=False) File "/tmp/hgtests.sv744r5t/install/lib/python/mercurial/hg.py", line 181, in openpath return url.open(ui, path, sendaccept=sendaccept) TypeError: openlargefile() got an unexpected keyword argument 'sendaccept' So, just accept and pass along any kwargs of the overridden function.
