     120== Speedup Git on Windows ==

     122Git tends to be rather slow for repositories with a huge amount of files on Windows.
     123One way to deal with that is to use a sparse-checkout, to "ignore" certain files.
     124The ''LayoutTests'' directory is certainly a good candidate, if you currently do not need these files.
     125A sparse-checkout uses a config file (''.git/info/sparse-checkout'') to determine if a file should be checked out or not.
     126Files mentioned in the config file will be part of the checkout.
     127Files not mentioned in the config file will be ignored.
     128There is also a syntax to invert this logic, but it is currently not working well with directories.
     129
     130  1. Create a ''sparse-checkout'' file with all the files/directories that you need. You can use the following command in git-bash to create such a file that will ignore the ''LayoutTests'' directory.
     131{{{
     132 cd WebKit
     133 ls -a | grep ".[a-zA-Z]" | grep -Ev "^.git|LayoutTests$" > .git/info/sparse-checkout
     134}}}
     135  2. Update the git tree cache
     136{{{
     137 git read-tree -m -u HEAD
     138}}}
     139
     140  2. Check which files have been excluded
     141{{{
     142 git ls-files -v | grep ^S
     143}}}
