Re: Hook to check for a presence of file before committing

Now let's say the development further goes on and now it is time to commit second time. At this time our hook script again will check for the presence of project.xml file and will also check if the project.xml got changed or not. If it got changed that means the developer did produce a new version of this file and we accept the commit. If the version of the file did not change then we reject it.

Here's a pre-commit hook script that requires that project.xml be in every commit. As we've discussed, I don't think this is what you really want, but it's what you say you want, so here it is and you can try it out and see what happens. I realize you are running Subversion on a Windows server, and this script is designed for UNIX or Mac OS X, but I am not a Windows programmer so I cannot write you a batch script. But perhaps seeing this script will give you ideas for how to write a batch script that does the same thing.

#!/bin/sh

# Parameters the Subversion server passes to this script.
REPOS="$1"
TXN="$2"

# Binaries we use.
AWK="/usr/bin/awk"
SVNLOOK="/usr/bin/svnlook"

# Abort if this file is not Added or Updated by this commit.
REQUIRED_FILE="project.xml"

MATCHED=$($SVNLOOK changed -t "$TXN" "$REPOS" \
    | $AWK '/^[AU_][U ] (.*\/)?'$REQUIRED_FILE'$/ { print }')

if [ -z "$MATCHED" ]; then
    echo "$REQUIRED_FILE was not part of the commit." 1>&2
    exit 1
fi

# All checks passed, so allow the commit.
exit 0
