Switching untracked files in Git with branches

Terrible.

#!/bin/sh

Setup

Pull out the variables we care about.

previous=$1 new=$2 branch=$3

For debugging purposes, we write out a file to the temp location.

date > $TEMP/install-branch-local-config.txt echo “previous $previous” >> $TEMP/install-branch-local-config.txt echo “new $new” >> $TEMP/install-branch-local-config.txt echo “branch $branch” >> $TEMP/install-branch-local-config.txt

Branch Naming

Figure out which branch we're going to be changing to. This is somewhat of an

inelegant method that just cycles through the heads (which contains a hash)

and figures out which branch head (based on the name). If there are multiple

heads for that commit, it will pick a random one. Likewise, if a specific

revision is checked out, this will assume “none”.

new_branch_name=“none”

for i in .git/refs/heads/* do hash=$(cat $i)

if [ "z$hash" = "z$new" ]
then
    new_branch_name=$(basename "$i")
    echo "trying new $i" >> $TEMP/install-branch-local-config.txt
fi

done

Figure out which branch we were on

old_branch_name=“none”

for i in .git/refs/heads/* do hash=$(cat $i)

if [ "z$hash" = "z$previous" ]
then
    old_branch_name=$(basename "$i")
    echo "trying previous $i" >> $TEMP/install-branch-local-config.txt
fi

done

Perform the manipulation

Figure out which files you want to swap around. We are using Local.config while

storing the old versions in Local-branchName.config. As we switch branches, we

move the files around.

In addition, Local-*.config is added to .git/info/exclude as a local change.

web_folder=“Website” local_config="$web_folder/Local-$new_branch_name.config" old_local_config="$web_folder/Local-$old_branch_name.config"

Report the files we're dealing with.

echo >> $TEMP/install-branch-local-config.txt echo “branch name $new_branch_name” >> $TEMP/install-branch-local-config.txt echo “web folder $web_folder” >> $TEMP/install-branch-local-config.txt echo “local config $local_config” >> $TEMP/install-branch-local-config.txt

Save off the old local config. We make sure we have a valid branch

then move Local.config into Local-branchName.config.

if [ “z$old_branch_name” != “znone” ] then if [ -f $web_folder/Local.config ] then cp $web_folder/Local.config $old_local_config fi fi

See if we have a new local config based on the branch, then move

it into the local config.

if [ -f $local_config ] then echo “found a file $local_config” >> $TEMP/install-branch-local-config.txt cp $local_config $web_folder/Local.config else echo “using standard config” >> $TEMP/install-branch-local-config.txt rm -f $web_folder/Local.config fi

Always touch Web.config to force IIS to restart

touch $web_folder/Web.config
