largefiles: for update -C, only update largefiles when necessary...
largefiles: for update -C, only update largefiles when necessary Before, a --clean update with largefiles would use the "optimization" that it didn't read hashes from standin files before and after the update. Instead of trusting the content of the standin files, it would rehash all the actual largefiles that lfdirstate reported clean and update the standins that didn't have the expected content. It could thus in some "impossible" situations automatically recover from some "largefile got out sync with its standin" issues (even there apparently still were weird corner cases where it could fail). This extra checking is similar to what core --clean intentionally do not do, and it made update --clean unbearable slow. Usually in core Mercurial, --clean will rely on the dirstate to find the files it should update. (It is thus intentionally possible (when trying to trick the system or if there should be bugs) to end up in situations where --clean not will restore the working directory content correctly.) Checking every file when we "know" it is ok is however not an option - that would be too slow. Instead, trust the content of the standin files. Use the same logic for --clean as for linear updates and trust the dirstate and that our "logic" will keep them in sync. It is much cheaper to just rehash the largefiles reported dirty by a status walk and read all standins than to hash largefiles. Most of the changes are just a change of indentation now when the different kinds of updates no longer are handled that differently. Standins for added files are however only written when doing a normal update, while deleted and removed files only will be updated for --clean updates.

Create test repository:
$ hg init repo
$ cd repo
$ echo x1 > x.txt
$ hg init foo
$ cd foo
$ echo y1 > y.txt
$ hg init bar
$ cd bar
$ echo z1 > z.txt
$ cd ..
$ echo 'bar = bar' > .hgsub
$ cd ..
$ echo 'foo = foo' > .hgsub
Add files --- .hgsub files must go first to trigger subrepos:
$ hg add -S .hgsub
$ hg add -S foo/.hgsub
$ hg add -S foo/bar
adding foo/bar/z.txt (glob)
