SVN pre-commit hook

Stop

How to avoid system files in your repository

Today Operating systems are often creating system files to accelerate directory operations:

MacOSX: ‘.DS_Store’
Windows: ‘Thumbs.db’
KDE: ‘.directory’
….

To avoid that these files mess up your repository, create inside the 'hook' directory a file named: 'pre-commit' (beside a the example file ‘pre-commit.tmpl’).
It is very important to make sure that the script has execution rights ( chmod a+x pre-commit )

#!/bin/bash
 
REPOS="$1"
TXN="$2"
 
SVNLOOK=/usr/bin/svnlook
 
# Make sure that the log message contains some text.
$SVNLOOK log -t "$TXN" "$REPOS" | grep "[a-zA-Z0-9]" > /dev/null
if [ $? -ne 0 ]; then
        echo "Log message not specified!" 1>&2
        exit 1
fi
 
# Do not commit crap like ...
CRAP_FILES=( '.DS_Store' 'Thumbs.db' '.directory' )
for FILE in $($SVNLOOK changed -t "$TXN" "$REPOS" | cut -b 5- | xargs basename); do
        for CRAP in "${CRAP_FILES[@]}"; do
                if [ "$FILE" = "$CRAP" ]; then
                        echo "Temporary files cannot be commited (ex: '.DS_Store', 'Thumbs.db')!" 1>&2
                        exit 1
                fi
        done
done
 
# All test passed
exit 0

Enjoy!
