diff: move b85diff to mdiff module
b85diff generates a binary diff, so we move this code to mdiff module
along with unidiff for text diffs. All diffing mechanisms will be in the
same place.
In an upcoming patch we will remove the responsibility to print the
index header from b85diff and move it back to patch, since it's
a patch metadata header, not part of the diff generation.
Test changesets filtering during exchanges (some tests are still in
test-obsolete.t)
$ cat > obs.py << EOF
> import mercurial.obsolete
> mercurial.obsolete._enabled = True
> EOF
$ echo '[extensions]' >> $HGRCPATH
$ echo "obs=${TESTTMP}/obs.py" >> $HGRCPATH
Push does not corrupt remote
----------------------------
Create a DAG where a changeset reuses a revision from a file first used in an
extinct changeset.
$ hg init local
$ cd local
$ echo 'base' > base
$ hg commit -Am base
adding base
$ echo 'A' > A
$ hg commit -Am A
adding A
$ hg up 0
0 files updated, 0 files merged, 1 files removed, 0 files unresolved
$ hg revert -ar 1
adding A
$ hg commit -Am "A'"
created new head
$ hg log -G --template='{desc} {node}'
