Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
copies-rust: extract the processing of a ChangedFiles in its own function This is a reasonably independent piece of code that we can extract in its own function. This extraction will be very useful for the next changeset, where we will change the iteration order (but still do the same kind of processing).

Start with a simple repository with a single commit

  $ hg init repo
  $ cd repo
  $ cat > .hg/hgrc << EOF
  > [extensions]
  > bundle2=$TESTTMP/bundle2.py
  > EOF

  $ echo A > A
  $ hg commit -A -m A -q
  $ cd ..

Clone

  $ hg clone -q repo clone

Add two linear commits

  $ cd repo
  $ echo B > B
  $ hg commit -A -m B -q
  $ echo C > C
  $ hg commit -A -m C -q

  $ cd ../clone
  $ cat >> .hg/hgrc <<EOF
  > [hooks]
  > pretxnchangegroup = sh -c "printenv.py --line pretxnchangegroup"
  > changegroup = sh -c "printenv.py --line changegroup"
  > incoming = sh -c "printenv.py --line incoming"
  > EOF
