hg: avoid auto sharing when the clone destination is remote Before this patch, when auto sharing is enabled, 'hg.clone()' tries to create local clone regardless of locality of the clone destination on the host, and causes failure. To avoid auto sharing when the clone destination is remote, this patch adds examination of 'islocal(dest)' before auto sharing in 'hg.clone()'. 'islocal(dest)' is examined after 'sharepool', because: - the former is more expensive than the latter - without enabling share extension, the later is always negative

largefiles: ensure lfutil.getstandinmatcher() only matches standins Previously, simply having the largefiles extension loaded without any largefiles added would crash when amending with -I. The problem was with no files in the matcher, the pattern list of files joined with 'standindir' was empty, and scmutil.match() would match everything. In lfutil.composestandinmatcher(), the match function is used to test if the file is a standin, and after getting a false positive, proceeds to call lfutil.splitstandin(). This returns None because it isn't a standin, which blows up when passed to rmatcher.matchfn(). Manually overriding _always in getstandinmatcher() probably isn't necessary anymore, but we leave well enough alone on stable. This regressed in ab618e52788a.

dirstate: add --minimal flag to debugrebuilddirstate On repositories with hundreds of thousands of files, hg debugrebuilddirstate causes every dirstate entry to be marked lookup, and the next hg status can take many minutes. This adds a --minimal flag that allows us to only rebuild the parts of the dirstate that are inconsistent. This follows two rules: 1) If a file is in the dirstate but not in the parent manifest, and it is not marked 'add', it is busted and we should drop it. 2) If a file is not in the dirstate at all, but it is in the parent manifest, it should be added to the dirstate and we need to mark it as lookup. This allows us to fix repositories where the dirstate doesn't match the manifest much more quickly. Tested by artificially adding bad dirstate entries (via code) for both cases above.
