When having trouble reproducing an issue, or testing a patch, start clean

I put this list together of things to try when one person in an issue is reporting results, but someone else is getting different results.

• git stash
• git checkout 8.x
• sudo rm -r sites
• git checkout sites
• git pull --rebase

The rm of sites, removes configuration files that might be left over from a previous install.

If things are really strange:

• sudo rm -r drupal
• git clone --recursive --branch 8.x http://git.drupal.org/project/drupal.git

Which is copy and pasted from http://drupal.org/project/drupal/git-instructions)

If I'm lucky and these work, then something like:

• drush am 432962

to get the most recent patch on an issue, checkout a new branch, and apply the patch.

(re) Installing

If I'm not testing an install screen, I use drush to install for me:

• drush -y si --account-pass=admin --db-url="mysql://root:root@localhost/drupal" --site-name="disable checker 432962"

If testing install, or just want to install by hand this is helpful to drop the tables before doing the install:

• drush -y sql-drop --db-url="mysql://root:root@localhost/drupal"

Browser cache

Then, if things are still strange, I clear my browser cache (or do a shift refresh/reload).
