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.

Set up a base, local, and remote changeset, as well as the working copy state. Files names are of the form base_remote_local_working-copy. For example, content1_content2_content1_content2-untracked represents a file that was modified in the remote changeset, left untouched in the local changeset, and then modified in the working copy to match the remote content, then finally forgotten. $ hg init Create base changeset $ python $TESTDIR/generate-working-copy-states.py state 3 1 $ hg addremove -q --similarity 0 $ hg commit -qm 'base' Create remote changeset $ python $TESTDIR/generate-working-copy-states.py state 3 2 $ hg addremove -q --similarity 0 $ hg commit -qm 'remote' Create local changeset $ hg update -q 0 $ python $TESTDIR/generate-working-copy-states.py state 3 3 $ hg addremove -q --similarity 0 $ hg commit -qm 'local' Set up working directory $ python $TESTDIR/generate-working-copy-states.py state 3 wc $ hg addremove -q --similarity 0 $ hg forget *_*_*_*-untracked $ rm *_*_*_missing-* $ hg status -A M content1_content1_content1_content4-tracked M content1_content1_content3_content1-tracked M content1_content1_content3_content4-tracked M content1_content2_content1_content2-tracked M content1_content2_content1_content4-tracked M content1_content2_content2_content1-tracked M content1_content2_content2_content4-tracked M content1_content2_content3_content1-tracked M content1_content2_content3_content2-tracked M content1_content2_content3_content4-tracked M content1_missing_content1_content4-tracked M content1_missing_content3_content1-tracked M content1_missing_content3_content4-tracked M missing_content2_content2_content4-tracked M missing_content2_content3_content2-tracked M missing_content2_content3_content4-tracked M missing_missing_content3_content4-tracked A content1_content1_missing_content1-tracked A content1_content1_missing_content4-tracked A content1_content2_missing_content1-tracked A content1_content2_missing_content2-tracked A content1_content2_missing_content4-tracked A content1_missing_missing_content1-tracked A content1_missing_missing_content4-tracked A missing_content2_missing_content2-tracked A missing_content2_missing_content4-tracked A missing_missing_missing_content4-tracked R content1_content1_content1_content1-untracked R content1_content1_content1_content4-untracked R content1_content1_content1_missing-untracked R content1_content1_content3_content1-untracked R content1_content1_content3_content3-untracked R content1_content1_content3_content4-untracked R content1_content1_content3_missing-untracked R content1_content2_content1_content1-untracked R content1_content2_content1_content2-untracked R content1_content2_content1_content4-untracked R content1_content2_content1_missing-untracked R content1_content2_content2_content1-untracked R content1_content2_content2_content2-untracked R content1_content2_content2_content4-untracked R content1_content2_content2_missing-untracked R content1_content2_content3_content1-untracked R content1_content2_content3_content2-untracked R content1_content2_content3_content3-untracked R content1_content2_content3_content4-untracked R content1_content2_content3_missing-untracked R content1_missing_content1_content1-untracked R content1_missing_content1_content4-untracked R content1_missing_content1_missing-untracked R content1_missing_content3_content1-untracked R content1_missing_content3_content3-untracked R content1_missing_content3_content4-untracked R content1_missing_content3_missing-untracked R missing_content2_content2_content2-untracked R missing_content2_content2_content4-untracked R missing_content2_content2_missing-untracked R missing_content2_content3_content2-untracked R missing_content2_content3_content3-untracked R missing_content2_content3_content4-untracked R missing_content2_content3_missing-untracked R missing_missing_content3_content3-untracked R missing_missing_content3_content4-untracked R missing_missing_content3_missing-untracked ! content1_content1_content1_missing-tracked ! content1_content1_content3_missing-tracked ! content1_content1_missing_missing-tracked ! content1_content2_content1_missing-tracked ! content1_content2_content2_missing-tracked ! content1_content2_content3_missing-tracked ! content1_content2_missing_missing-tracked ! content1_missing_content1_missing-tracked ! content1_missing_content3_missing-tracked ! content1_missing_missing_missing-tracked ! missing_content2_content2_missing-tracked ! missing_content2_content3_missing-tracked ! missing_content2_missing_missing-tracked ! missing_missing_content3_missing-tracked ! missing_missing_missing_missing-tracked ?

This should be the files for which the base (1st filename segment), the remote (2nd segment) and the working copy (4th segment) are all different. Interestingly, one untracked file got merged and added, which corresponds to the odd 'if force and branchmerge and different' case in manifestmerge(). $ hg resolve -l U content1_content2_content1_content4-tracked R content1_content2_content2_content1-tracked U content1_content2_content2_content4-tracked R content1_content2_content3_content1-tracked U content1_content2_content3_content3-tracked U content1_content2_content3_content4-tracked R content1_content2_missing_content1-tracked U content1_content2_missing_content4-tracked U missing_content2_content2_content4-tracked U missing_content2_content3_content3-tracked U missing_content2_content3_content4-tracked U missing_content2_missing_content4-tracked U missing_content2_missing_content4-untracked Check status and file content Some files get added (e.g. content1_content2_content1_content1-untracked) It is not intuitive that content1_content2_content1_content4-tracked gets merged while content1_content2_content1_content4-untracked gets overwritten. Any *_content2_*-untracked triggers the modified/deleted prompt and then gets overwritten. A lot of untracked files become tracked, for example content1_content2_content2_content2-untracked. *_missing_missing_missing-tracked is reported as removed ('R'), which doesn't make sense since the file did not exist in the parent, but on the other hand, merged-in additions are reported as modifications, which is almost as strange. missing_missing_content3_missing-tracked becomes removed ('R'), even though the remote side did not touch the file $ for f in `python $TESTDIR/generate-working-copy-states.py filelist 3` > do > echo > hg status -A $f > if test -f $f > then > cat $f > else > echo '<missing>' > fi > if test -f ${f}.orig > then > echo ${f}.orig: > cat ${f}.orig > fi > done C content1_content1_content1_content1-tracked content1 R content1_content1_content1_content1-untracked content1 M content1_content1_content1_content4-tracked content4 R content1_content1_content1_content4-untracked content4 ! content1_content1_content1_missing-tracked <missing> R content1_content1_content1_missing-untracked <missing> M content1_content1_content3_content1-tracked content1 R content1_content1_content3_content1-untracked content1 C content1_content1_content3_content3-tracked content3 R content1_content1_content3_content3-untracked content3 M content1_content1_content3_content4-tracked content4 R content1_content1_content3_content4-untracked content4 ! content1_content1_content3_missing-tracked <missing> R content1_content1_content3_missing-untracked <missing> A content1_content1_missing_content1-tracked content1 ?
