For our (AuScope/CSIRO) svn repos, we have an svn pre-commit script that
uses svnlook to require a log message and to prevent commits to tags.
Commits to tags are usually unintended and always ill-advised.
Would the GT-dev community like to adopt a must-have-logs and
no-commits-to-tags policy and enforce it using this script?
hooks/pre-commit:
#!/bin/sh
# [1] REPOS-PATH (the path to this repository)
# [2] TXN-NAME (the name of the txn about to be committed)
#
REPOS="$1"
TXN="$2"
noLogMessage() {
echo "Please provide a log message" >&2
exit 1
}
# Make sure that the log message contains some text.
SVNLOOK=/usr/bin/svnlook
$SVNLOOK log -t "$TXN" "$REPOS" | \
grep "[a-zA-Z0-9]" >/dev/null || noLogMessage
TAGS_REGEX='tags/[^/]\+'
# Get list of transactions in the 'tag' directory
TAGS_CHANGES=`"$SVNLOOK" changed -t "$TXN" "$REPOS" 2>/dev/null | \
awk '{ print $2; }' 2>/dev/null | \
grep ^tags/ 2>/dev/null | \
sed -e "s!^\($TAGS_REGEX\).*!\1!" | \
sort | \
uniq`
# Get head revision number
YOUNGEST=`svnlook youngest "$REPOS" 2>/dev/null`
# For every line in transaction,
# check to see if directory in tags exists
for CHANGE in $TAGS_CHANGES; do
# If directory in tags exists, deny transaction
if svnlook proplist -r $YOUNGEST "$REPOS" "$CHANGE" >/dev/null 2>&1 ;
then
echo "Cannot modify existing tag: ${tag}" >&2
exit 1
fi
done
# All checks passed, so allow the commit.
exit 0
