SVN pre-commit hook to ensure that all files referenced in .csproj are versioned?

Question

Sometimes we transfer a C # project file to SVN, which refers to files that we forgot to add to SVN. Are there any commit authentication scripts that process the .csproj file and reject the commit if it refers to unversioned files?

Answer 1

#!/usr/bin/perl
# Checks for source files which have been added to a csproj in a commit
# but haven't themselves been committed.
use Modern::Perl;
use warnings FATAL => 'syntax';
use File::Basename qw(basename);
use XML::Simple;

die "usage: $0 repo transaction\n" if @ARGV != 2;
my $opt = "-t"; # -r for testing
my ($repos, $txn) = @ARGV;

# If you really, really want to add a file to the proj and
# not commit it, start your commit message with a !
my @info = `svnlook info $opt $txn "$repos"`;
exit 0 if ($info[3] =~ /\A!/);

my @lines = `svnlook changed $opt $txn "$repos"`;

my @projects = grep { /\AU/ }
               grep { /[.]csproj\z/ }
               map { chomp; $_ } @lines;

my @filelist = `svnlook tree $opt $txn "$repos" --full-paths`;
my %present;

foreach (@filelist) {
    chomp;
    $present{$_} = 1;
}

foreach (@projects) {
    m"\AU.\s\s([\w/.]+/)([\w]+\.csproj)\z" or die "bad line $_";
    my ($path, $proj) = ($1, $2);

    my $projfile = `svnlook cat $opt $txn "$repos" $path/$proj`;
    my $xml = XMLin($projfile);

    # Tested with VS 2012 project files
    my @includes = @{$xml->{ItemGroup}->[1]->{Compile}};
    # All the source files in the csproj
    my @filenames = map {$_->{Include}} @includes;

    foreach (@filenames) {
        # ignore "../etc", not below the project file in the tree
        next if /\A[.][.]/;
        # if you have files that are in the proj but shouldn't be committed
        # eg some generated files, add checks for them here
        # next if /MyGeneratedFile.cs\z/;

        my $file = $path . $_;
        # The csproj file speaks windows paths, but svn will output unix ones
        $file =~ tr|\\|/|;

        if (!defined $present{$file}) {
            die "The file $file is included in the project $path\\$proj, but is not present in the tree, did you forget to commit it?";
        }
    }
}

If you use a Windows server, you can look at Subversion Notify for Windows - http://sourceforge.net/projects/svn-notify/
