For those using git with WebKit and have cloned the git repository git://git.webkit.org/WebKit.git, I think it would be useful to add a .gitignore file. I've attached an example file that could be used for this. My example has Mac-related ignores, so you might want to make some additions for other platforms.
Created attachment 30425 [details] Example .gitignore file
Since we use SVN as our version control system I don't think it's a great idea to clutter up the tree with dot files related to a different system. To avoid this problem yourself you can put entries in $GIT_DIR/info/exclude, which functions as an ignore file for your own repository.
I just discovered that this was implemented in <http://trac.webkit.org/changeset/50325> for https://bugs.webkit.org/show_bug.cgi?id=30951 I should note that nobody notified me of this. Also, the WebKit team should review its policy of closing bugs as WONTFIX. If you close a bug as WONTFIX and then actually fix the bug several months later without even reopening the original bug, something is wrong with the procedure. *** This bug has been marked as a duplicate of bug 30951 ***
