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 repo $ cd repo 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_content1-untracked U content1_content2_content1_content2-untracked U content1_content2_content1_content4-tracked U content1_content2_content1_content4-untracked U content1_content2_content1_missing-tracked U content1_content2_content1_missing-untracked R content1_content2_content2_content1-tracked U content1_content2_content2_content1-untracked U content1_content2_content2_content2-untracked U content1_content2_content2_content4-tracked U content1_content2_content2_content4-untracked U content1_content2_content2_missing-tracked U content1_content2_content2_missing-untracked R content1_content2_content3_content1-tracked U content1_content2_content3_content1-untracked U content1_content2_content3_content2-untracked U content1_content2_content3_content3-tracked U content1_content2_content3_content3-untracked U content1_content2_content3_content4-tracked U content1_content2_content3_content4-untracked U content1_content2_content3_missing-tracked U content1_content2_content3_missing-untracked R content1_content2_missing_content1-tracked U content1_content2_missing_content1-untracked U content1_content2_missing_content2-untracked U content1_content2_missing_content4-tracked U content1_content2_missing_content4-untracked U content1_content2_missing_missing-tracked U content1_content2_missing_missing-untracked U content1_missing_content1_content4-tracked U content1_missing_content3_content3-tracked U content1_missing_content3_content4-tracked U content1_missing_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 $ checkstatus() { > 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 '' > fi > done > } $ checkstatus 2>&1 | tee $TESTTMP/status1 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 R content1_content1_content1_missing-untracked 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 R content1_content1_content3_missing-untracked A content1_content1_missing_content1-tracked content1 ?
