[cfe-dev] How to update from svn?

[David Blaikie via cfe-dev]

I think everyone has their own little scripts for this - I have one for
git-svn that goes a little something like this (though it freaks out if
there's an untracked directory - like a newly created but not yet git add'd
one).

We should possibly get one such script checked into the repo as an
authoritative tool:

#!/bin/sh

if ! git remote -v 2> /dev/null | grep "http://llvm.org/git" > /dev/null; then
  echo "Not an llvm git repo"
  exit 1
fi

while ! git remote -v 2> /dev/null | grep
"http://llvm.org/git/llvm.git" > /dev/null; do
  if ! git remote -v 2> /dev/null > /dev/null; then
    echo "Could not find the root of the llvm git repository"
    exit 1
  fi
  cd `git rev-parse --show-toplevel`/../
done

cd `git rev-parse --show-toplevel` > /dev/null

function fetchAndRebase {
  if [ -d $1 ]; then
    pushd $1 > /dev/null
    if git status > /dev/null; then
      (git stash | grep "No local changes to save" > /dev/null
      STASHED=$?
      git fetch > /dev/null
      git svn rebase -l
      if [ $STASHED -ne 0 ]; then git stash pop > /dev/null; fi) &
      for dir in `git status --ignored | grep /$ | sed -e "s/^#//"`; do
        fetchAndRebase $dir
      done
    fi
    popd > /dev/null
  fi
}

fetchAndRebase `git rev-parse --show-toplevel`
wait
