How to use git with an svn repo

Do you have a subversion repo? Think you're stuck with outdated subversion workflows? Not anymore! Use the fabulous git to work with your subversion hosted code:

git svn clone https://example.com/path/to/trunk -T trunk -b branches -t tags

(may take a long time with large repos, e.g. several days)

Now you can rebase your code! You can do all your work with git - easily branch, stash, rebase, blame, etc. - and when you're done, push back to subversion.

(source)

See subversion branches:
git branch -r

Update the git repo (may take several hours for large repos - you don't need to run this more than once):
git svn fetch --fetch-all

Update the current branch (run this on trunk/master instead of "fetch" above):
git svn rebase

Temporarily skip a test until a specific date

The job of a test suite is to alert the developers of a potential problem. Once that's happened, the only value in continuing to fail is to nag and remind them to make a change. In real life sometimes fixing issues takes a long time. If they're already tracking changes in a ticketing system, or actively working on a fix, the failure becomes noise, and can hide other unexpected failures. There should be no such thing as an "okay failure" which can be ignored - you need to stop it failing if the fix is already planned. But you don't want to risk forgetting about it. So you can disable it for a short time, to allow the developer to fix the underlying issue. In the future, perhaps CI frameworks might feature a Nagios-style "acknowledge" function.

This is one solution for now:

use Test::More;
use DateTime;

my $expected_to_fail = (
    ($test_data = 'foo')
    &&
    ! deadline_has_passed( DateTime->new( year => 2014, month => 11, day => 23 ) # the future
) ? 1 : 0;

SKIP: {
    skip "while we do something (ticket ID)", 1 if $expected_to_fail;
    ok( "some test" );
}

sub deadline_has_passed {
    my ($deadline) = @_;
    my $today = DateTime->now; #->add( days => 30 );
    my $deadline_has_passed = (DateTime->compare( $today, $deadline ) < 1) ? 0 : 1;

    # debug
    #note("today    = ".$today->ymd);
    #note("deadline = ".$deadline->ymd);
    #note("compare today,deadline => ". DateTime->compare( $today, $deadline ));
    #note("has deadline passed? $deadline_has_passed");

    return $deadline_has_passed;
}
