upgrade: implement partial upgrade for upgrading persistent-nodemap Upgrading repositories to use persistent nodemap should be fast and easy as it requires only two things: 1) Updating the requirements 2) Writing a persistent-nodemap on disk For both of the steps above, we don't need to edit existing revlogs. This patch makes upgrade only do the above mentioned two steps if we are only upgarding to use persistent-nodemap feature. Since `nodemap.persist_nodemap()` assumes that there exists a nodemap file for the given revlog if we are trying to call it, this patch adds `force` argument to create a file if does not exist which is true in our upgrade case. The test changes demonstrate that we no longer write nodemap files for manifest after upgrade which I think is desirable. Differential Revision: https://phab.mercurial-scm.org/D9936

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.

diff: add experimental support for "merge diffs" The way this works is it re-runs the merge and "stores" conflicts, and then diffs against the conflicted result. In a normal merge, you should only see diffs against conflicted regions or in cases where there was a semantic conflict but not a textual one. This makes it easier to detect "evil merges" that contain substantial new work embedded in the merge commit. Differential Revision: https://phab.mercurial-scm.org/D8504
